3 * fns.c (Fdelq, Fdelete): Doc fix.
5 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
8 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
10 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
12 * lisp.h (make_lisp_ptr): New macro to replace XSET.
13 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
16 2012-09-09 Eli Zaretskii <eliz@gnu.org>
18 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
19 left fringe if the window has a left margin. This avoids leaving
20 traces of the cursor because its leftmost pixel is not drawn over.
22 * dispnew.c (update_window_line): When the left margin area of a
23 screen line is updated, set the redraw_fringe_bitmaps_p flag of
24 that screen line. (Bug#12277)
26 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
28 Assume C89 or later for math functions (Bug#12381).
29 This simplifies the code, and makes it a bit smaller and faster,
30 and (most important) makes it easier to clean up signal handling
31 since we can stop worring about floating-point exceptions in
32 library code. That was a problem before C89, but the problem
33 went away many years ago on all practical Emacs targets.
34 * data.c, image.c, lread.c, print.c:
35 Don't include <math.h>; no longer needed.
36 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
37 might be autoconfigured, as that never happens.
39 * doprnt.c (DBL_MAX_10_EXP):
41 Remove. C89 or later always defines these.
42 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
43 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
44 (arith_error, domain_error, domain_error2):
45 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
46 no longer needed -- we simply return what C returns. All uses removed.
47 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
49 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
50 Remove. All uses expanded, as these macros are no longer used
51 more than once and are now more trouble than they're worth.
52 (Ftan): Use tan, not sin / cos.
53 (Flogb): Assume C89 frexp.
54 (fmod_float): Assume C89 fmod.
55 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
56 (init_floatfns): Remove. All uses removed.
58 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
60 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
61 compositeToPoint for OSX < 10.6 (Bug#12390).
63 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
65 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
66 This produces more-accurate results.
68 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
70 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
73 2012-09-08 Chong Yidong <cyd@gnu.org>
75 * syntax.c (Fstring_to_syntax): Doc fix.
77 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
79 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
80 in the internal border.
81 (x_set_window_size): Remove static variables and their usage.
82 (ns_redraw_scroll_bars): Fix NSTRACE arg.
83 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
84 fringe/internal border adjustment (Bug#11052).
85 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
86 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
87 (ns_fix_rect_ibw): Remove.
88 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
89 (ns_dumpglyphs_box_or_relief): Ditto.
90 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
92 (ns_dumpglyphs_image): Ditto.
93 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
95 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
96 their usage. Add fringe_extended_p and its use as in other terms.
97 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
98 scroll bar was removed.
99 (updateFrameSize): New function.
100 (windowDidResize): Move code to updateFrameSize and call it.
102 * nsterm.h (EmacsView): Add updateFrameSize.
104 2012-09-07 Chong Yidong <cyd@gnu.org>
106 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
108 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
110 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
112 More signal-handler cleanup (Bug#12327).
113 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
114 Problem introduced when merging patches. Noted by Eli Zaretskii in
115 <http://bugs.gnu.org/12327#67>.
116 * floatfns.c: Comment fix.
117 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
118 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
119 and anyway the declaration is harmless even if SIGDANGER is not defined.
120 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
121 defined BROKEN_FIONREAD). systty.h formerly did this, but other
122 source files not surprisingly expected syssignal.h to define, or
123 not define, SIGIO, and it's cleaner to do it that way, for consistency.
124 Include <sys/ioctl.h>, for FIONREAD.
125 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
126 This eliminates a problem whereby other files mysteriously had
127 to include "syssignal.h" before including "systty.h" if they
128 wanted to use "#ifdef SIGIO".
130 2012-09-07 Eli Zaretskii <eliz@gnu.org>
132 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
134 * w32.c (sigemptyset): Empty the set.
135 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
137 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
139 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
141 * alloc.c (mark_buffer): Revert unsafe marking optimization.
142 (mark_object): Likewise for frame objects.
144 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
146 * syssignal.h (handle_on_main_thread): Always declare,
147 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
148 This ports to platforms without HAVE_PTHREAD.
150 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
152 Signal-handler cleanup (Bug#12327).
153 Emacs's signal handlers were written in the old 4.2BSD style with
154 sigblock and sigmask and so forth, and this led to some
155 inefficiencies and confusion. Rewrite these to use
156 pthread_sigmask etc. without copying signal sets around. Also,
157 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
158 'signal', and instead use functions that do not attempt to take
159 over the system name space. This patch causes Emacs's text
160 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
161 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
162 Do not include <signal.h> or "syssignal.h", as these
163 modules do not use signals.
164 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
165 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
166 Do not include <signal.h>, as "syssignal.h" does that for us now.
167 * atimer.c (sigmask_atimers): New function.
168 (block_atimers, unblock_atimers): New functions,
169 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
171 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
172 no longer needed here.
173 * emacs.c (main): Inspect existing signal handler with sigaction,
174 so that there's no need to block and unblock SIGHUP.
175 * sysdep.c (struct save_signal): New member 'action', replacing
176 old member 'handler'.
177 (save_signal_handlers, restore_signal_handlers):
178 Use sigaction instead of 'signal' to save and restore.
179 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
180 New function. All users of 'signal' modified to use set_sighandler
181 if they're writeonly, and to use sys_signal if they're read+write.
182 (emacs_sigaction_init, forwarded_signal): New functions.
183 (sys_signal): Remove. All uses replaced by calls to sigaction
184 and emacs_sigaction_init, or by direct calls to 'signal'.
185 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
186 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
187 all uses replaced by pthread_sigmask etc. calls.
188 * syssignal.h: Include <signal.h>.
189 (emacs_sigaction_init, forwarded_signal): New decls.
190 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
191 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
192 (sigmask, sys_sigmask): Remove; no longer needed.
193 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
194 (sigblock, sigunblock, sigfree):
195 (sigsetmask) [!defined sigsetmask]:
196 Remove. All uses replaced by pthread_sigmask.
197 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
198 no longer need to be replaced, and its typical old uses
199 are now done via emacs_sigaction_init and sigaction.
200 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
201 (sys_sigdel): Remove; unused.
202 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
204 2012-09-06 Eli Zaretskii <eliz@gnu.org>
206 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
207 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
209 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
211 Explicitly mark buffer_defaults and buffer_local_symbols.
212 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
213 mark_local_symbols here.
214 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
215 since special buffers aren't marked here any more.
216 (allocate_buffer): Chain new buffer with all_buffers here...
217 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
219 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
220 (syms_of_buffer): Remove staticpro of the above.
221 (init_buffer_once): Set names for buffer_defaults and
222 buffer_local_symbols.
224 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
226 Use bool for booleans in font-related modules.
227 * font.c (font_intern_prop, font_style_to_value)
228 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
229 (generate_otf_features, font_check_otf_features, font_check_otf)
230 (font_match_p, font_list_entities, font_at):
231 * fontset.c (fontset_id_valid_p, reorder_font_vector
232 (fontset_find_font, Fset_fontset_font)
233 (face_suitable_for_char_p) [0]:
234 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
235 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
236 (m17n_flt_initialized, ftfont_shape_by_flt):
237 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
238 * nsfont.m (nsfont_draw):
239 * w32font.c (w32font_draw):
240 * w32term.c (x_draw_glyphless_glyph_string_foreground):
241 Use bool for booleans.
242 * font.h: Adjust to above API changes.
243 (struct font, struct font_driver, struct font_driver_list):
244 Use bool for booleans.
245 (struct font): Remove useless member encoding_type.
247 * fontset.c, xftfont.c: Omit unnecessary static decls.
249 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
251 * alloc.c (mark_object): Revert window marking code
252 since it's unsafe for the Fset_window_configuration.
254 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
256 Fix race conditions with signal handlers and errno (Bug#12327).
257 Be more systematic about preserving errno whenever a signal
258 handler returns, even if it's not in the main thread. Do this by
259 renaming signal handlers to distinguish between signal delivery
260 and signal handling. All uses changed.
261 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
262 * data.c (deliver_arith_signal): Rename from arith_error.
263 * dispnew.c (deliver_window_change_signal): Rename from
264 window_change_signal.
265 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
266 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
267 * keyboard.c (deliver_input_available_signal): Rename from
268 input_available_signal.
269 (deliver_user_signal): Rename from handle_user_signal.
270 (deliver_interrupt_signal): Rename from interrupt_signal.
271 * process.c (deliver_pipe_signal): Rename from send_process_trap.
272 (deliver_child_signal): Rename from sigchld_handler.
273 * atimer.c (handle_alarm_signal):
274 * data.c (handle_arith_signal):
275 * dispnew.c (handle_window_change_signal):
276 * emacs.c (handle_fatal_signal, handle_danger_signal):
277 * keyboard.c (handle_input_available_signal):
278 * keyboard.c (handle_user_signal, handle_interrupt_signal):
279 * process.c (handle_pipe_signal, handle_child_signal):
280 New functions, with the actual signal-handling code taken from the
281 original respective signal handlers, sans the sporadic attempts to
282 preserve errno, since that's now done by handle_on_main_thread.
283 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
284 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
285 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
287 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
288 Move initialization of main_thread to sysdep.c's init_signals.
289 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
290 our usage, and simplifies the mainline code.
291 (record_child_status_change): New static function, as a helper
292 for handle_child_signal, and with most of the old child handler's
294 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
295 (handle_child_signal): Use the above.
296 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
297 Moved here from emacs.c.
298 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
299 code moved here from emacs.c's main function.
300 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
301 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
302 lets callers save and restore errno properly.
304 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
306 Remove redundant or unused things here and there.
307 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
308 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
309 * editfns.c (Fcompare_buffer_substrings): Likewise.
310 * frame.h (struct terminal, struct font_driver_list):
311 Remove redundant declarations.
312 * window.h (Qleft, Qright): Likewise.
314 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
316 Do not mark objects from deleted buffers, windows and frames.
317 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
318 (mark_object): Likewise for windows and frames.
320 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
322 * alloc.c (valid_lisp_object_p): Treat killed buffers,
323 buffer_defaults and buffer_local_symbols as valid objects.
324 Return special value to denote them.
326 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
328 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
329 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
330 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
331 (file_name_absolute_p, Fsubstitute_in_file_name):
332 (check_executable, check_writable, Ffile_accessible_directory_p)
333 (Fset_file_selinux_context, Fdefault_file_modes)
334 (Finsert_file_contents, choose_write_coding_system)
335 (Fwrite_region, build_annotations, a_write, e_write)
337 * filelock.c (boot_time_initialized, get_boot_time)
338 (get_boot_time_1, lock_file_1, within_one_second):
339 * floatfns.c (in_float):
340 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
341 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
342 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
343 * lisp.h (struct Lisp_Hash_Table.cmpfn):
344 * window.c (compare_window_configurations):
345 Use bool for booleans.
346 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
347 (Fdefault_file_modes): Now mode_t, not int, for modes.
348 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
349 (internal_delete_file): Now returns void, not a (boolean) int,
350 since nobody was looking at the return value.
351 * lisp.h, window.h: Adjust to above API changes.
353 * xdisp.c (set_message): Simplify and reindent last change.
355 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
357 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
359 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
361 * eval.c (call_debugger): Make the function non-static so that we
362 can call it from set_message.
364 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
365 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
367 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
369 Give more-useful info on a fatal error (Bug#12328).
370 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
371 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
372 of doing the work ourselves.
373 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
375 (fatal_error_backtrace): New function, taken from the guts
376 of the old fatal_error_signal, but with a new option to output
378 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
379 info about the signal than just its number.
380 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
381 * sysdep.c: Include <execinfo.h>
382 (emacs_backtrace): New function, taken partly from the previous
383 code of the 'die' function.
384 (emacs_abort): Call fatal_error_backtrace rather than abort.
386 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
388 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
389 eager (load-time) macro-expansion.
390 * lisp.mk (lisp): Add macroexp.
392 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
394 Simplify redefinition of 'abort' (Bug#12316).
395 Do not try to redefine the 'abort' function. Instead, redo
396 the code so that it calls 'emacs_abort' rather than 'abort'.
397 This removes the need for the NO_ABORT configure-time macro
398 and makes it easier to change the abort code to do a backtrace.
399 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
400 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
401 Remove; sysdep.c's emacs_abort now takes its place.
402 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
403 'abort' changed to use 'emacs_abort'.
404 * msdos.c (dos_abort) [defined abort]: Remove; not used.
405 (abort) [!defined abort]: Rename to ...
406 (emacs_abort): ... new name.
407 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
408 the place of the old 'abort' in emacs.c.
409 * w32.c, w32fns.c (abort): Do not #undef.
410 * w32.c (emacs_abort): Rename from w32_abort.
412 2012-09-04 Eli Zaretskii <eliz@gnu.org>
414 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
415 offsets[j].dv, since the y axis of the screen coordinates points
416 down, while the y axis of the font definition coordinates points
417 up. This fixes display of Arabic diacritics such as KASRA and
418 KASRATAN. (Bug#11860)
420 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
422 Be more systematic about _setjmp vs setjmp.
423 * alloc.c (test_setjmp, mark_stack):
424 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
425 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
426 (png_load, my_error_exit, jpeg_load):
427 * process.c (send_process_trap, send_process):
428 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
429 The underscored versions are up to 30x faster on some hosts.
430 Formerly, the code used setjmp+longjmp sometimes and
431 _setjmp+_longjmp at other times, with no particular reason to
432 prefer setjmp+longjmp.
434 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
436 Fix minor problem found by static checking.
437 * buffer.c (Fdelete_all_overlays): Return nil.
439 2012-09-03 Martin Rudalics <rudalics@gmx.at>
441 * buffer.c (Fdelete_all_overlays): New function.
443 2012-09-03 Chong Yidong <cyd@gnu.org>
445 * gtkutil.c: Add extern decl for Qxft.
447 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
449 * emacs.c, eval.c: Use bool for boolean.
450 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
451 (malloc_using_checking) [DOUG_LEA_MALLOC]:
452 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

564 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
565 more than one grapheme cluster passed to the shaper: compute the

568 * image.c: Restore mistakenly removed inclusion of w32.h. Without
569 it, GCC doesn't see prototypes of w32_delayed_load, and complains

720 Add window_closed and button_values. Add void as return value for
721 add(Button|String|Split). addButton takes int instead of Lisp_Object.

920 (char_table_set_range, optimize_sub_char_table)
921 (map_sub_char_table):
922 Use bool for boolean.
923 * character.c (str_to_unibyte): Omit last boolean argument; it was
924 always 0. All callers changed.
925 * character.h, charset.h: Adjust to match previous changes.
926 * character.h (char_printable_p): Remove decl of nonexistent function.
927 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
928 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
929 are all boolean, so make them single-bit bitfields.
931 * lisp.h (ASET): Remove attempt to detect side effects.
932 It was meant to be temporary and it often doesn't work,
933 because when IDX has side effects the behavior of IDX==IDX
934 is undefined. See Stefan Monnier in
935 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
937 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
939 * lisp.h (functionp): New function (extracted from Ffunctionp).
941 * eval.c (Ffunctionp): Use it.
943 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
945 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
946 as that's faster and simpler than static storage. Don't bother
947 with the g_main_context_query overhead if g_main_context_pending
948 says no events are pending.
949 (gfds, gfds_size): Remove these static vars.
950 (xgselect_initialize): Remove; no longer needed.
951 All uses and decls removed.
953 * emacs.c (fatal_error_signal_hook): Remove.
954 All uses removed. This leftover from old code was always 0.
956 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
957 * casefiddle.c (casify_object, casify_region):
958 * casetab.c (set_case_table):
959 * category.c, category.h (word_boundary_p):
960 * category.h (CHAR_HAS_CATEGORY):
961 Use bool for booleans, instead of int.
963 2012-08-25 Eli Zaretskii <eliz@gnu.org>
965 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
967 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
969 On assertion failure, print backtrace if available.
970 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
971 (die) [ENABLE_CHECKING]: Print a backtrace if available.
972 * Makefile.in (LIB_EXECINFO): New macro.
975 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
976 * bytecode.c (exec_byte_code):
977 * callint.c (check_mark, Fcall_interactively):
978 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
979 (getenv_internal, sync_process_alive, call_process_exited):
980 * lisp.h (USE_SAFE_ALLOCA):
981 Use bool for booleans, instead of int.
982 * lisp.h, process.h: Adjust prototypes to match above changes.
983 * callint.c (Fcall_interactively): Don't assume the mark's
984 offset fits in 'int'.
986 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
988 * buffer.c, buffer.h: Use bool for boolean.
989 * buffer.c (reset_buffer_local_variables)
990 (buffer_lisp_local_variables, Fset_buffer_modified_p)
991 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
992 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
993 (overlay_touches_p, overlay_strings, Foverlay_put)
994 (report_overlay_modification, call_overlay_mod_hooks):
995 (mmap_enlarge, mmap_set_vars):
996 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
997 Use bool for booleans, instead of int.
998 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
999 since the 1-or-0 return value is always ignored anyway.
1000 (mmap_initialized_p):
1001 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1002 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1004 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1006 * bidi.c: Use bool for boolean.
1007 This is a bit more readable, and makes the text segment of bidi.o
1008 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1009 Presumably it's faster too.
1010 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1012 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1013 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1014 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1015 (bidi_explicit_dir_char, bidi_level_of_next_char)
1016 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1017 Use bool for booleans, instead of int.
1018 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1019 (bidi_unshelve_cache): Adjust decls to match code.
1021 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1023 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1026 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1028 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1029 * atimer.h: Include <stdbool.h>.
1031 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1033 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1034 compile time tests instead of run time tests on systems that do
1036 (FRAME_MAC_P): Remove leftover from deleted code.
1037 * frame.c (syms_of_frame): Remove leftover from deleted code.
1039 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1041 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1043 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1045 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1046 Otherwise, the compiler complains about (A?B:C) where B is void
1047 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1048 (fontset_add): Return void, for FONTSET_ADD.
1050 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1052 * alloc.c: Use bool for booleans.
1053 (gc_in_progress, abort_on_gc)
1054 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1055 (dont_register_blocks) [GC_MALLOC_CHECK]:
1056 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1057 (check_string_bytes, make_specified_string, memory_full)
1058 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1059 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1060 (mark_stack, valid_pointer_p, make_pure_string)
1061 (Fgarbage_collect, survives_gc_p, gc_sweep):
1062 Use bool for booleans, instead of int.
1063 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1064 Remove unused local.
1065 * alloc.c (PURE_POINTER_P):
1066 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1067 * editfns.c (Fformat):
1068 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1070 * fns.c (sweep_weak_table):
1071 * lisp.h (suppress_checking, push_message, survives_gc_p)
1072 (make_pure_string, gc_in_progress, abort_on_gc):
1073 * lread.c (readchar, read1):
1074 * print.c (Fprin1_to_string):
1075 * xdisp.c (push_message):
1076 Use bool for booleans affected directly or indirectly by
1079 Make recently-introduced setters macros.
1080 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1081 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1082 (set_fontset_default, set_fontset_fallback): Rename from their
1083 upper-case counterparts, and make them functions rather than macros.
1084 This is more consistent with the other recently-introduced setters.
1085 These don't need to be inline, since they're local.
1087 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1089 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1090 the loop (Bug#12247).
1092 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1094 * lisp.h (vcopy): Use memcpy rather than our own loop.
1095 This fixes a performance regression introduced by the recent
1096 addition of vcopy. This means 'vcopy' will need to be modified
1097 for a copying collector, but that's OK. Also, tighten the
1098 checking in the assertion.
1100 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1102 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1103 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1104 non-base glyph for the width of the base character, according to
1105 what x_draw_composite_glyph_string_foreground expects.
1106 Generate WADJUST value according to composition_gstring_width's
1107 expectations, to produce correct width of the composed character.
1108 Reverse the sign of the DU offset produced by ScriptPlace.
1110 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1112 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1114 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1116 Avoid direct writes to contents member of struct Lisp_Vector.
1117 * lisp.h (vcopy): New function to copy data into vector.
1118 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
1119 * fns.c (Ffillarray): Use ASET.
1120 * keyboard.c (timer_check_2): Use AREF and ASET.
1121 (append_tool_bar_item, Frecent_keys): Use vcopy.
1122 * lread.c (read_vector): Use ASET.
1123 * msdos.c (Frecent_doskeys): Use vcopy.
1124 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1125 (Finternal_merge_in_global_face): Use ASET and vcopy.
1126 * xfont.c (xfont_list_pattern): Likewise.
1128 2012-08-21 Martin Rudalics <rudalics@gmx.at>

1131 the position of its buffer's point.
1132 (Fset_window_point): For the selected window always go in its
1133 buffer to the specified position.
1135 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1137 Setter macros for fontsets.
1138 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1139 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1140 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1143 2012-08-20 Glenn Morris <rgm@gnu.org>
1145 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1146 Don't assume that `ln -f' works.
1148 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1150 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1151 and later about non-assignments with no effect. See discussion at
1152 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1155 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1157 Inline setter functions for Lisp_Objects slots of struct specbinding.
1158 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1161 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1163 * window.c (select_window): Always make selected window's buffer
1166 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1168 Use AREF and ASET for docstrings of category tables.
1169 * category.h (CATEGORY_DOCSTRING): Use AREF.
1170 (SET_CATEGORY_DOCSTRING): Use ASET.
1171 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1173 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1175 Inline setter functions for hash table members.
1176 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
1177 (set_hash_hash, set_hash_index): Rename with _slot suffix.
1178 (set_hash_key_and_value, set_hash_index, set_hash_next)
1179 (set_hash_hash): New functions.
1180 * charset.c, fns.c: Adjust users.
1182 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1184 Inline getter and setter functions for per-buffer values.
1185 * buffer.h (per_buffer_default, set_per_buffer_default)
1186 (per_buffer_value, set_per_buffer_value): New functions.
1187 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
1188 * buffer.c, data.c: Adjust users.
1190 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
1192 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
1194 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1196 Rely on <config.h> + <unistd.h> to declare 'environ',
1197 as gnulib does this if the system doesn't.
1198 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1199 Remove declaration. MS-Windows declares it on stdlib.h which is
1200 included by conf_post.h.
1201 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1202 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
1203 * vm-limit.c: Include <unistd.h>, for 'environ'.
1205 * unexaix.c, unexcoff.c: Include "mem-limits.h".
1206 (start_of_data): Remove decl; mem-limits.h provides it.
1208 * xdisp.c (handle_invisible_prop): Make it a bit faster
1209 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1211 2012-08-19 Chong Yidong <cyd@gnu.org>
1213 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
1216 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
1218 * .gdbinit: Use call instead of set when calling a function in the
1221 * data.c (set_internal): Don't use set_blv_found.
1222 (Fkill_local_variable): Likewise.
1224 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
1226 * nsfont.m (ns_ascii_average_width): Ensure the string
1227 ascii_printable is initialized with a null-terminated character
1228 array. Otherwise, it can contain undesired extra characters.
1230 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1232 port new setting code to Sun C 5.8 2005/10/13
1233 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1234 Return void, not Lisp_Object. Otherwise, the compiler
1235 complains about (A?B:C) where B is void and C is Lisp_Object
1236 when compiling CHAR_TABLE_SET, due to the recent change to
1237 the API of sub_char_table_set_contents.
1239 2012-08-18 Chong Yidong <cyd@gnu.org>
1241 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
1242 for the string case (Bug#3874).
1244 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
1246 * buffer.h (BSET): Remove (Bug#12215).

1316 New setter functions.
1318 * termhooks.h (TSET): Remove (Bug#12215).
1319 Replace all uses with calls to new setter functions.
1320 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
1321 (TERMHOOKS_INLINE): New macro.
1322 (tset_charset_list, tset_selection_alist): New setter functions.
1323 * terminal.c (TERMHOOKS_INLINE):
1324 Define to EXTERN_INLINE, so that the corresponding functions
1325 are compiled into code.
1326 (tset_param_alist): New setter function.
1328 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
1330 * keyboard.h (KSET): Remove (Bug#12215).

2074 value of EMACSLOADPATH, as it is no longer needed.
2075 (check_windows_init_file): Now external, not static.

2126 * alloc.c (record_xmalloc): New function.
2127 * lisp.h (record_xmalloc): New decl.
2128 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts

2130 needed. All uses changed.
2131 * print.c (print_string, print_error_message): Avoid length recalc.
2133 Improve fix for macroexp crash with debugging (Bug#12118).

2171 called from 'lstat'.
2172 (stat, lstat): New functions, call 'stat_worker'.
2173 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2174 symlinks when the underlying filesystem supports them.

2179 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2180 checking subscripts; problem introduced with the recent
2181 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2182 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2183 since it's used in non-static inline functions now.
2185 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

2687 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
2688 (enum enum_USE_LSB_TAG):
2689 New enum types, packaging up enums that need to be exported to GDB.

2710 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
2712 Fast save_excursion_save and save_excursion_restore.
2713 * lisp.h (struct Lisp_Excursion): New data type.
2714 (PVEC_EXCURSION): New pseudovector type.
2715 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
2716 to deal with it. Adjust comments.

2731 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
2732 emacs.c, as this is a more-suitable home. Had this been done earlier
2733 the fix for 12036 would have avoided some of the problems noted in
2734 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
2735 would have been more obvious.
2736 * emacs.c: Do not include <verify.h>; no longer needed.
2737 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
2738 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
2739 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2740 Remove; now done in lisp.h.
2741 * lisp.h (PUBLISH_TO_GDB): New macro.

2745 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
2746 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
2747 not be usable in #if. This simplifies things.
2749 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
2751 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
2753 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

2756 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
2757 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
2758 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
2759 Adjust to changes in lisp.h and emacs.c, by using
2760 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
2761 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
2762 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
2763 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
2764 instead of gdb_valbits.
2765 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
2766 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
2767 instead of gdb_array_mark_flag.
2768 (xboolvector): Get size from $->size, not $->header.size.
2769 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
2770 (xreload, hook-run, hookpost-run): Remove.
2771 * emacs.c: Include <verify.h>.
2772 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
2773 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
2775 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
2776 (gdb_USE_LSB_TAG): New enum constants.
2777 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
2778 Also define these as enum constants, so they're visible to GDB.
2779 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
2780 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
2781 as constants, so they're visible to GDB.
2782 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
2783 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
2784 Now enum constants, not macros, so they're visible to GDB.
2785 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
2786 more convenient now. All uses changed.
2787 (VALMASK) [USE_LSB_TAG]: Also define in this case.
2788 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
2790 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

2797 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
2798 add argument, tune behavior, and adjust all callers.
2800 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
2802 Use typedef for EMACS_INT, EMACS_UINT.
2803 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
2804 than macros. This simplifies debugging in the usual case, since
2805 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
2806 and it allows expressions involving EMACS_INT casts.
2807 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
2809 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

2819 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
2821 Adjust buffer text indirection counters at the end of Fkill_buffer.
2822 * buffer.c (Fkill_buffer): Adjust indirection counters when the
2823 buffer is definitely dead. This should really fix an issue reported
2824 by Christoph Scholtes again. (Bug#12007).
2825 (init_buffer_once): Initialize indirection counters of
2826 buffer_defaults and buffer_local_symbols (for sanity and safety).
2828 2012-07-24 Eli Zaretskii <eliz@gnu.org>
2830 * xdisp.c (init_iterator): Don't compute dimensions of truncation
2831 and continuation glyphs on tooltip frames, leave them at zero.
2832 Avoids continued lines in tooltips. (Bug#11832)
2834 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

2859 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
2861 Swap buffer text indirection counters in Fbuffer_swap_text.
2862 * buffer.c (Fbuffer_swap_text): Swap indirections too.
2863 This avoids crash reported by Christoph Scholtes at
2864 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
2866 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
2868 * nsmenu.m (Popdown_data): New struct.

2873 and autorelease them. Also autorelease img and matrix (Bug#12005).
2874 (dealloc): Remove (Bug#12005).

2891 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
2893 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
2894 as it's limited by the amount of memory, not by INT_MAX.
2896 2012-07-21 Eli Zaretskii <eliz@gnu.org>
2898 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
2899 in special-event-map. See the discussion at

2980 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
2981 'for_each_per_buffer_object_at'.
2982 All uses changed. It's better to use upper-case for macros that

3045 padding before the data member of a bool vector.
3046 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
3047 than doing the check by hand with an abort ().
3049 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3051 * eval.c (Fdefvar): Don't check constants since we only set the var if
3052 it's not yet defined anyway (bug#11904).
3054 * lisp.h (last_undo_boundary): Declare new var.
3055 * keyboard.c (command_loop_1): Set it.
3056 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
3057 were auto-added by the command loop (bug#11774).
3059 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>

3621 Remove "#define unix" that is no longer needed (Bug#11905).
3622 * s/aix4-2.h (unix): Remove; no longer needed.
3624 EMACS_TIME simplification (Bug#11875).
3625 This replaces macros (which typically do not work in GDB)
3626 with functions, typedefs and enums, making the code easier to debug.
3627 The functional style also makes code easier to read and maintain.
3628 * systime.h: Include <sys/time.h> on all hosts, not just if
3629 WINDOWSNT, since 'struct timeval' is needed in general.
3630 (EMACS_TIME): Now a typedef, not a macro.
3631 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
3633 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
3634 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

3636 (EMACS_TIME_LE): Now functions, not macros.
3637 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
3638 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
3639 which are not functions. All uses rewritten to use:
3640 (make_emacs_time): New function.
3641 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
3642 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
3643 not functions. All uses rewritten to use the following, respectively:
3644 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
3645 (add_emacs_time, sub_emacs_time): New functions.
3646 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
3647 * fileio.c (Fcopy_file):
3648 * xterm.c (XTflash): Get the current time closer to when it's used.
3649 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

3656 * frame.c (Fmake_terminal_frame):
3657 * gtkutil.c (get_utf8_string):
3659 * nsmenu.m (ns_update_menubar):
3660 * regex.c (regerror):
3661 Prefer memcpy to strncpy and strncat when either will do.
3662 * fileio.c (Fsubstitute_in_file_name):
3663 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
3664 (menu_separator_name_p):
3665 * nsmenu.m (ns_update_menubar):
3666 Prefer memcmp to strncmp when either will do.
3667 * nsterm.m: Include <ftoastr.h>.
3669 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
3670 Prefer snprintf to strncpy.
3671 * nsterm.m (ns_term_init):
3672 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
3673 * nsterm.m (ns_term_init):
3674 Avoid the need for strncpy, by using build_string or
3675 make_unibyte_string directly. Use dtoastr, not snprintf.
3676 * process.c (Fmake_network_process): Diagnose service names that
3677 are too long, rather than silently truncating them or creating
3678 non-null-terminated names.
3679 (Fnetwork_interface_info): Likewise, for interface names.
3680 * sysdep.c (system_process_attributes) [GNU_LINUX]:
3681 Prefer sprintf to strncat.
3682 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
3683 Prefer vsnprintf to vsprintf + strncpy.
3685 2012-07-10 Glenn Morris <rgm@gnu.org>
3687 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
3688 Clarify fallback case.
3690 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3692 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
3693 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
3694 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
3695 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
3696 where argument type is known to be a Lisp_Cons.
3698 2012-07-10 Tom Tromey <tromey@redhat.com>
3700 * bytecode.c (BYTE_CODE_THREADED): New macro.
3701 (BYTE_CODES): New macro. Replaces all old byte-code defines.

3708 Optimize pure C strings initialization.
3709 * lisp.h (make_pure_string): Fix prototype.
3710 (build_pure_c_string): New function, defined as static inline. This
3711 provides a better opportunity to optimize away calls to strlen when
3712 the function is called with compile-time constant argument.
3713 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
3714 argument, adjust users accordingly. Use build_pure_c_string where
3716 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
3717 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
3718 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
3720 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3722 Avoid calls to strlen in miscellaneous functions.
3723 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
3724 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
3725 * lread.c (openp): Likewise.
3727 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
3729 Avoid calls to strlen in path processing functions.
3730 * fileio.c (file_name_as_directory): Add comment. Change to add
3731 srclen argument and return the length of result. Adjust users
3733 (directory_file_name): Fix comment. Change to add srclen argument,
3734 swap 1st and 2nd arguments to obey the common convention.
3735 Adjust users accordingly.
3736 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
3738 2012-07-10 Glenn Morris <rgm@gnu.org>
3740 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
3741 Move PENDING_OUTPUT_COUNT definition to configure.
3743 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
3744 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
3745 * s/gnu.h (DATA_START): Move definitions to configure.
3747 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
3748 We include usg5-4-common.h, which defines them both.
3750 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
3751 O_RDONLY already includes it).
3753 Stop ns builds setting the EMACSLOADPATH environment variable.
3754 * nsterm.m (ns_load_path): Rename from ns_init_paths.
3755 Now it does not set EMACSLOADPATH, just returns the load-path string.
3756 * nsterm.h: Update accordingly.
3757 * lread.c [HAVE_NS]: Include nsterm.h.
3758 (init_lread) [HAVE_NS]: Use ns_load_path.
3759 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
3761 2012-07-09 Glenn Morris <rgm@gnu.org>
3763 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
3764 since the included bsd-common.h does so.
3766 Stop ns builds setting the EMACSPATH environment variable.
3767 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
3768 (ns_init_paths): Do not set EMACSPATH.
3769 * nsterm.h (ns_exec_path): Add it.
3770 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
3773 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
3775 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
3777 * process.c (wait_reading_process_output): 'waitchannels' was unset
3778 when read_kbd || !NILP (wait_for_cell); fix this.
3780 Add GCC-style 'const' attribute to functions that can use it.
3781 * character.h (char_resolve_modifier_mask):
3782 * keyboard.h (make_ctrl_char):
3783 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
3784 (init_character_once, next_almost_prime, init_fns, init_image)
3785 (flush_pending_output, init_sound):
3786 * mem-limits.h (start_of_data):

3790 Declare the dummy function with ATTRIBUTE_CONST.
3791 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
3792 Add decls with ATTRIBUTE_CONST.
3794 Minor improvements to make_formatted_string.
3795 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
3796 where int is good enough, as vsprintf returns an int.
3797 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
3799 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3801 Use make_formatted_string to avoid double length calculation.
3802 * lisp.h (make_formatted_string): New prototype.
3803 * alloc.c (make_formatted_string): New function.
3804 * buffer.c (Fgenerate_new_buffer_name): Use it.
3805 * dbus.c (syms_of_dbusbind): Likewise.

3808 * frame.c (make_terminal_frame, set_term_frame_name)
3809 (x_report_frame_params): Likewise.
3810 * image.c (gs_load): Likewise.
3811 * minibuf.c (get_minibuffer): Likewise.

3826 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
3828 Move marker debugging code under MARKER_DEBUG.
3829 * marker.c (MARKER_DEBUG): Move marker debugging code under
3830 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
3831 for bootstrap with --enable-checking (~3x slowdown reported
3832 by Juanma Barranquero <lekktu@gmail.com>).
3833 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
3835 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
3837 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
3838 See <http://bugs.gnu.org/11825#29>.
3840 2012-07-08 Eli Zaretskii <eliz@gnu.org>
3842 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
3843 has no font, use the frame's font. (Bug#11813)
3844 (display_line): Add commentary about displaying truncation glyphs
3846 (produce_special_glyphs): Move here from term.c.
3848 * term.c (produce_special_glyphs): Move to xdisp.c.
3850 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
3853 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
3855 * xdisp.c (display_line): Avoid warning about implicit declaration
3858 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
3860 * lisp.h: Remove empty conditional.
3862 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3864 * lread.c (load_path_check): Now static.
3866 Fix some minor --with-ns problems found by static checking.
3867 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
3868 (x_set_font) [!HAVE_X_WINDOWS]:
3869 * image.c (xpm_load_image) [HAVE_NS]:
3870 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
3871 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
3872 Remove unused local.
3873 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
3874 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
3875 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
3876 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
3877 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
3878 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
3879 Fix pointer signedness problem.
3880 * xfaces.c (FRAME_X_FONT_TABLE):
3881 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
3883 2012-07-07 Glenn Morris <rgm@gnu.org>
3885 * lread.c (load_path_check): New function, split from init_lread.
3886 (init_lread): Reorganize. Motivation:
3887 If EMACSLOADPATH is set, check/warn about that rather than the
3888 defaults, which we are not going to use. Hence we can remove
3889 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
3890 Don't warn if site-lisp directories are missing.
3891 If not installed, start from a blank load-path, since
3892 PATH_LOADSEARCH refers to the eventual installation directories.
3894 2012-07-07 Eli Zaretskii <eliz@gnu.org>
3896 Support truncation and continuation glyphs on GUI frames, when
3897 fringes are disabled. (Bug#11832)
3898 * xdisp.c (init_iterator): Get dimensions of truncation and
3899 continuation glyphs even if on GUI frames.
3900 Adjust it->last_visible_x on GUI frames when the left or right fringes,
3901 or both, are absent.
3902 (start_display, move_it_in_display_line_to): Handle the case of a
3903 GUI frame without a fringe to display continuation or truncation
3905 (insert_left_trunc_glyphs): Support GUI frames: make sure
3906 truncation glyphs overwrite enough glyphs from the current line to
3907 have sufficient space in pixels.
3908 (display_line): Support truncation and continuation glyphs on GUI
3909 frames. If some spare pixels are left on the line after inserting
3910 the truncation glyphs, fill that space with a stretch glyph of a
3911 suitably computed width.
3913 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
3914 produce_glyphs, to support GUI sessions.
3916 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
3918 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
3920 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
3922 Do not require float-time's arg to fit in time_t (Bug#11825).
3923 This works better on hosts where time_t is unsigned, and where
3924 float-time is applied to the (negative) difference between two times.
3925 * editfns.c (decode_time_components): Last arg is now double *,
3926 not int *, and means to store all the result as a double, without
3927 worrying about whether the seconds part fits in time_t.
3928 All callers changed.
3929 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
3930 All callers changed.
3931 (Ffloat_time): Do not fail merely because the specified time falls
3932 outside of time_t range.
3934 2012-07-07 Glenn Morris <rgm@gnu.org>
3936 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

3940 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
3942 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
3943 Update dependencies.
3945 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
3947 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3949 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
3950 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
3951 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
3952 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
3953 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
3954 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
3956 * xfont.c (compare_font_names): Redo to omit the need for casts.
3958 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
3960 * xfns.c (Fx_change_window_property): Doc fix.
3961 * w32fns.c (Fx_change_window_property): Doc fix.
3963 * w32fns.c (Fx_window_property): Accept the same arguments as the
3964 X Windows version. Doc fix.
3965 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
3967 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
3968 Eli Zaretskii <eliz@gnu.org>
3970 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
3971 Windows-specific code from nt/config.nt moved here.
3972 Obsolete settings removed.
3974 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3976 * process.c: Avoid unnecessary calls to gettime.
3977 (wait_reading_process_output): Don't get the time of day
3978 when gobbling data immediately and not waiting, as there's no need
3979 for it in that case. This removes a FIXME.
3981 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
3983 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
3984 is defined (Bug#11768).
3986 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3988 Fix marker debugging code.

3990 if buffer is not multibyte.
3991 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3992 Call byte_char_debug_check with correct arguments.
3994 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3996 Compile marker debugging code only if ENABLE_CHECKING is defined.
3997 * marker.c (byte_char_debug_check, count_markers):
3998 Use only if ENABLE_CHECKING is defined.
3999 (byte_debug_flag): Remove.
4000 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4001 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4003 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4005 Avoid code repetition in marker-related functions.
4006 * marker.c (attach_marker): New function.
4007 (Fset_marker, set_marker_restricted, set_marker_both)
4008 (set_marker_restricted_both): Use it.

4027 * editfns.c (buildmark): Remove.
4028 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
4029 (save_restriction_save): Use build_marker.
4030 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
4031 * window.c (save_window_save): Likewise.
4033 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4035 Do not use Fdelete_overlay in delete_all_overlays
4036 to avoid redundant calls to unchain_overlay.
4037 * buffer.c (drop_overlay): New function.
4038 (delete_all_overlays, Fdelete_overlay): Use it.
4039 * minibuf.c (get_minibuffer): Fix comment.
4041 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4043 Port to OpenBSD 5.1 amd64.
4044 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4045 This is needed for OpenBSD, and should be harmless on all BSD systems.
4046 Also, include <sys/sysctl.h>, as it should be available on all
4047 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4048 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4049 use p_pid member, not kp_proc.pid.
4051 2012-07-06 Glenn Morris <rgm@gnu.org>
4053 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4055 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4057 More xmalloc and related cleanup.
4058 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

4065 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
4066 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4068 Omit needless casts involving void * pointers and allocation.
4069 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4070 as the former is more robust if P's type is changed.
4071 Prefer xzalloc to xmalloc + memset 0.
4072 Simplify malloc-or-realloc to realloc.
4073 Don't worry about xmalloc returning a null pointer.
4074 Prefer xstrdup to xmalloc + strcpy.
4075 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
4077 * keyboard.c (apply_modifiers_uncached): Prefer local array to
4078 alloca of a constant.
4080 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4082 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4083 hscroll is larger than the line width. Fixes long and futile
4084 looping inside extend_face_to_end_of_line (on a TTY) producing
4085 glyphs that are not needed and thrown away.
4087 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4089 * marker.c (set_marker_restricted_both): Simplify by using
4092 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4094 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4096 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4098 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4099 not defined (Bug#11768).
4100 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4101 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4102 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4103 followed by gtk_box_set_homogeneous (Bug#11768).
4104 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4105 (update_theme_scrollbar_width, xg_create_scroll_bar):
4106 Use gtk_scrollbar_new (Bug#11768).
4107 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4108 (is_box_type): New function (Bug#11768).
4109 (xg_tool_item_stale_p): Call is_box_type.
4110 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4111 with default display (Bug#11768).

4115 * xdisp.c (window_hscroll_limited): New function.
4116 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4117 coordinates when window's hscroll is set to insanely large
4120 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
4122 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
4123 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
4125 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4128 * lisp.h (xzalloc): New prototype. Omit needless casts.
4129 * alloc.c (xzalloc): New function. Omit needless casts.

4181 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4183 * fileio.c (time_error_value): Check the right error number.
4184 Problem reported by Troels Nielsen in
4185 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4187 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4189 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4190 This should be fixed in a better way; see Eli Zaretskii in
4191 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4192 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4194 * fileio.c (time_error_value): Rename from special_mtime.
4195 The old name's problems were noted by Eli Zaretskii in
4196 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4198 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4199 This variable's comment says Emacs needs at least one GDB-visible
4200 symbol of type enum pvec_type, to work around GDB problems.
4201 The symbol's value doesn't matter.
4203 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4204 that causes compilation to fail on pre-C99 compilers.
4206 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
4208 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
4209 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
4211 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4213 * buffer.c (init_buffer_once): Fix initialization of
4214 headers for buffer_defaults and buffer_local_symbols.
4215 Reported by Juanma Barranquero <lekktu@gmail.com>.
4217 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
4219 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
4220 * lisp.h (enum pvec_type): Use fewer bits.
4221 (PSEUDOVECTOR_SIZE_BITS): New constant.
4222 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4223 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4224 change in pvec_type.
4225 (PSEUDOVECTOR_TYPEP): New macro.
4226 (TYPED_PSEUDOVECTORP): Use it.
4227 * fns.c (internal_equal): Adapt code to extract pvectype.

4231 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4232 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4233 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4234 abusing vector->header.next.nbytes.
4235 (live_vector_p): Use PVEC_TYPE.
4236 (mark_object): Adapt code to extract pvectype. Use switch.
4238 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4240 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4241 Tighten new eassert a bit.
4243 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4245 Fix compilation with --enable-gcc-warnings and -O1
4247 * doprnt.c (doprnt): Change type of tem to int, initialize
4248 to avoid compiler warning. Add eassert.
4249 * search.c (simple_search): Initialize match_byte to avoid
4250 compiler warning. Add eassert.
4252 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4254 Avoid weird behavior with large horizontal scrolls.
4255 Without this change, for example, large hscroll values would
4256 mess up Emacs's display on Fedora 15 x86, presumably due to
4257 overflows in int calculations in the display code.
4258 Also, if buffers had long lines, Emacs would freeze.
4259 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4260 (set_window_hscroll): New function, containing the old guts of
4261 Fset_window_hscroll. Return the clipped value.
4262 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4263 This avoids the need to check against PTRDIFF_MAX.
4265 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4267 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4269 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
4271 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4273 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4274 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4275 since GCC 4.4.6 issues a bogus warning for them.
4277 Fix bugs in file timestamp newness comparisons.
4278 * fileio.c (Ffile_newer_than_file_p):
4279 * lread.c (Fload): Use full timestamp resolution of files,
4280 not just the 1-second resolution, so that files that are only
4281 slightly newer still count as newer.
4282 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4283 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4285 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4287 * fileio.c: Improve handling of file time marker. (Bug#11852)
4288 (special_mtime): New function.
4289 (Finsert_file_contents, Fverify_visited_file_modtime):
4290 Use it to set special mtime values consistently.
4292 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
4294 * fileio.c (Finsert_file_contents): Properly handle st_mtime
4295 marker for non-existing file. (Bug#11852)
4297 2012-07-03 Glenn Morris <rgm@gnu.org>
4299 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4300 and did not make it into globals.h).
4302 2012-07-03 Tom Tromey <tromey@redhat.com>
4304 * window.c (Fset_window_margins, Fset_window_fringes)
4305 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
4306 * textprop.c (Fprevious_property_change): No longer static.
4307 * syntax.c (Fsyntax_table_p): No longer static.

4329 * intervals.h: Remove EXFUNs.
4330 * fontset.h: Remove EXFUN.

4335 * w32term.h: Remove EXFUNs.
4336 * window.h: Remove EXFUNs.
4337 * xsettings.h: Remove EXFUN.
4338 * xterm.h: Remove EXFUN.
4340 2012-07-03 Glenn Morris <rgm@gnu.org>
4342 * lisp.h (Frandom): Make it visible to C.
4343 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
4344 buffer for invisible buffers. (Bug#1229)
4346 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4348 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4349 values which aren't power of 2.
4350 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4351 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4354 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
4356 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
4358 * alloc.c (mark_object): Revert part of last patch to use `switch'.
4360 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4362 * alloc.c (allocate_vector_block): Remove redundant
4363 calls to mallopt if DOUG_LEA_MALLOC is defined.
4364 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
4365 avoid calls to mallopt if zero_vector is returned.
4367 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4369 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
4370 is enabled, avoid dereferencing NULL current_sblock if
4373 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
4375 Cleanup basic buffer management.
4376 * buffer.h (struct buffer): Change layout to use generic vector
4377 marking code. Fix some comments. Change type of 'clip_changed'
4378 to bitfield. Remove unused #ifndef old.
4379 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
4380 (GET_OVERLAYS_AT): Fix indentation.
4381 (for_each_per_buffer_object_at): New macro.
4382 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
4383 (Fbuffer_local_variables): Use it.
4384 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
4385 * alloc.c (allocate_buffer): Adjust to match new layout of
4386 struct buffer. Fix comment.
4387 (mark_overlay): New function.
4388 (mark_buffer): Use it. Use mark_vectorlike to mark normal
4389 Lisp area of struct buffer.
4390 (mark_object): Use it. Adjust marking of misc objects
4391 and related comments.
4393 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4395 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4396 wrapper that is not needed because the wrapped code is a no-op (zero
4397 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4398 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4400 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4402 * alloc.c (mark_buffer): Simplify. Remove prototype.
4403 (mark_object): Add comment. Reorganize marking of vector-like
4404 objects. Use CHECK_LIVE for all vector-like objects except buffers
4405 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4406 Avoid redundant calls to mark_vectorlike for bool vectors.
4408 2012-06-30 Glenn Morris <rgm@gnu.org>
4410 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
4412 * epaths.in (PATH_SITELOADSEARCH): New.
4413 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
4414 This is rather than relying on --enable-locallisppath elements
4415 having "site-lisp" in their names. (Bug#10208#25, 11658)
4417 2012-06-30 Eli Zaretskii <eliz@gnu.org>
4419 * w32proc.c (sys_select): Accept and ignore one more argument.
4421 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4423 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4424 (pselect) [!MS_DOS]: Redirect to sys_select.
4426 * sysdep.c: Don't include dos.h and dosfns.h.
4428 * process.c (sys_select):
4429 * msdos.c (sys_select): Accept one more argument and ignore it.
4431 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4432 adapt data types and code to that.
4435 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4436 which clashes with the gnulib function of the same name.
4438 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4440 * font.c (font_style_to_value, font_style_symbolic)
4441 (font_prop_validate_style): Add type checks for values in
4444 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
4446 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
4449 2012-06-29 Eli Zaretskii <eliz@gnu.org>
4451 * xdisp.c (try_window_id): Undo last change.
4453 * w32.c (getwd): Adjust commentary about startup_dir.
4454 (init_environment): Always call sys_access, even in non-MSVC
4455 builds. Don't chdir to the directory of the Emacs executable.
4456 This undoes code from 1997 which was justified by the need to
4457 "avoid conflicts when removing and renaming directories". But its
4458 downside was that every relative file name was being interpreted
4459 relative to the directory of the Emacs executable, which can never
4460 be TRT. In particular, it broke sys_access when called with
4461 relative file names.
4462 (sys_access): Map GetLastError to errno.
4464 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4466 * window.h (struct window): Change type of 'fringes_outside_margins'
4467 to bitfield. Fix comment. Adjust users accordingly.
4468 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
4470 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
4473 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
4475 * gnutls.c (emacs_gnutls_handshake):
4476 Add QUIT to make the loop interruptible.
4478 2012-06-29 Glenn Morris <rgm@gnu.org>
4480 * charset.c (init_charset): Make lack of etc/charsets fatal.
4482 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4484 * editfns.c (region_limit): Fix type mismatch.
4486 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
4488 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
4489 undefined. Convert from xassert to eassert.
4490 * nsmenu.m: Convert from xassert to eassert.
4491 * nsterm.m: Likewise.
4493 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
4495 * editfns.c (region_limit): Clip to narrowing (bug#11770).
4497 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
4499 Avoid integer overflow on scroll-left and scroll-right.

4656 Use sprintf return value instead of invoking strlen on result.
4657 In the old days this wasn't portable, since some sprintf
4658 implementations returned char *. But they died out years ago and
4659 Emacs already assumes sprintf returns int.
4660 Similarly for float_to_string.
4661 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

4669 Use sprintf or float_to_string result to avoid need to call strlen.
4670 * data.c (Fnumber_to_string):
4671 Use make_unibyte_string, since the string must be ASCII.
4672 * lisp.h, print.c (float_to_string): Now returns int length.
4673 * term.c (produce_glyphless_glyph):
4674 Use sprintf result rather than recomputing it.
4676 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
4677 * Makefile.in (ALL_CFLAGS):
4678 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

4707 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
4709 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
4710 `const char *' to `char *' to avoid compiler warning.
4712 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
4714 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
4715 instead of truncating it to 63 (admittedly a generous limit).

4774 * dispnew.c (Fsleep_for, sit_for):
4775 * keyboard.c (kbd_buffer_get_event):
4776 * process.c (Faccept_process_output):
4777 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
4778 This improves on the previous patch, which introduced a bug
4779 when time_t is unsigned and as wide as intmax_t.
4780 See <http://bugs.gnu.org/9000#51>.
4782 2012-06-23 Eli Zaretskii <eliz@gnu.org>
4784 * dispnew.c (sit_for, Fsleep_for):
4785 * keyboard.c (kbd_buffer_get_event):

4799 Privately reported by Herbert J. Skuhra.
4800 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

4803 not make_lisp_timeval, when the argument is of type EMACS_TIME.
4805 2012-06-23 Eli Zaretskii <eliz@gnu.org>
4807 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
4808 last argument of make_unibyte_string.

4811 language ID in the event parameters.
4813 * w32term.c (w32_read_socket): Put the new keyboard codepage into
4814 event.code, not the obscure "character set ID".

4837 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
4838 Privately reported by Herbert J. Skuhra.

4845 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
4847 Support higher-resolution time stamps (Bug#9000).
4848 The time stamps are only nanosecond-resolution at the C level,
4849 since that's the best that any real-world system supports now.
4850 But they are picosecond-resolution at the Lisp level, as that's
4851 easy, and leaves room for future OS improvements.
4853 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
4856 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
4857 Don't get current time unless it's needed.
4859 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
4860 now provides it if it's absent.
4861 (start_atimer): Port to higher-res time stamps.
4862 Check for time stamp overflow. Don't get current time more
4863 often than is needed.
4865 * buffer.h (struct buffer): Buffer modtime now has high resolution.
4866 Include systime.h, not time.h.
4867 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
4869 * dired.c: Include stat-time.h.
4870 (Ffile-attributes): File times now have higher resolution.

4873 (struct image): Timestamp now has higher resolution.
4875 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
4876 has at least microseconds now. All uses removed.
4877 (update_frame, update_single_window, update_window, update_frame_1)
4878 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
4879 (duration_to_sec_usec): Remove; no longer needed.
4881 * editfns.c (time_overflow): Now extern.
4882 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
4883 (float-time, Fformat_time_string, Fcurrent_time_string)

4887 (decode_time_components, lisp_seconds_argument): New functions.
4888 (make_time): Now static.
4889 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
4890 Report an error if the time is invalid, rather than having the caller
4893 * fileio.c: Include <stat-time.h>
4894 (Fcopy_file): Copy higher-resolution time stamps.
4895 Prefer to set the time stamp via a file descriptor if that works.
4896 (Fset_file_times, Finsert_file_contents, Fwrite_region)
4897 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
4898 (Fvisited_file_modtime, Fset_visited_file_modtime):
4899 Support higher-resolution time stamps.
4901 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
4903 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
4905 * image.c (prepare_image_for_display, clear_image_cache)
4906 (lookup_image): Port to higer-resolution time stamps.
4908 * keyboard.c (start_polling, bind_polling_period):
4909 Check for time stamp overflow.
4910 (read_char, kbd_buffer_get_event, timer_start_idle)
4911 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
4912 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
4913 Port to higher-resolution time stamps. Do not assume time_t is signed.
4914 (decode_timer): New function. Timers are now vectors of length 9,
4915 not 8, to accommodate the picosecond component.
4916 (timer_check_2): Use it.
4918 * nsterm.m (select_timeout, timeval_subtract): Remove.
4919 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
4920 as they're a bit more accurate and handle overflow better.
4921 (ns_select): Change prototype to be compatible with pselect.
4922 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
4923 * nsterm.h (ns_select): Adjust prototype.
4925 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
4926 us-resolution time stamps.
4927 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
4929 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
4931 * lisp.h (time_overflow): New decl.
4932 (wait_reading_process_output): First arg is now intmax_t, not int,
4933 to accommodate larger waits.
4935 * process.h (struct Lisp_Process.read_output_delay):
4936 Now counts nanoseconds, not microseconds.
4937 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
4939 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
4940 (wait_reading_process_output):
4941 Port to ns-resolution time stamps.
4942 (Faccept_process_output, wait_reading_process_output):
4943 Check for time stamp overflow. Do not assume time_t is signed.
4944 (select_wrapper): Remove; we now use pselect.
4945 (Fprocess_attributes): Now generates ns-resolution time stamps.
4947 * sysdep.c: Include utimens.h. Don't include utime.h
4948 or worry about struct utimbuf; gnulib does that for us now.
4949 (gettimeofday): Remove; gnulib provides a substitute.
4950 (make_timeval): New function.
4951 (set_file_times): Now sets ns-resolution time stamps.
4952 New arg FD; all uses changed.
4953 (time_from_jiffies, ltime_from_jiffies, get_up_time)
4954 (system_process_attributes):
4955 Now returns ns-resolution time stamp. All uses changed.
4956 Check for time stamp overflow.
4958 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
4959 provides a substitute now.
4961 * systime.h: Include timespec.h rather than sys/time.h and time.h,
4962 since it guarantees struct timespec.
4963 (EMACS_TIME): Now struct timespec, so that we can support
4964 ns-resolution time stamps.
4965 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
4966 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
4967 (EMACS_USECS): Remove.
4968 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
4969 so multiply the arg by 1000 before storing it.
4970 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
4972 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
4973 Port to ns-resolution time stamps.
4974 (EMACS_TIME_NEG_P): Remove; replaced by....
4975 (EMACS_TIME_SIGN): New macro.
4976 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
4977 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
4978 (set_file_times, make_time, lisp_time_argument): Adjust signature.
4979 (make_timeval, make_lisp_time, decode_time_components): New decls.
4980 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
4981 that it mishandled time_t overflow. You can't compare by subtracting!
4982 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
4983 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
4985 * term.c: Include <sys/time.h>.

5022 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5023 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

5074 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
5075 gets killed during executing of this function (Bug#11665).
5076 Try to always return Qt when the buffer has been actually killed.
5077 (Vkill_buffer_query_functions): In doc-string say that functions
5078 run by this hook should not change the current buffer.
5080 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
5082 Fix recently-introduced process.c problems found by static checking.

5103 This removes the need for CHECK.
5104 (CHECK): Remove. Its comments about always evaluating its
5105 argument were confusing, as 'eassert' typically does not evaluate
5108 * coding.c (produce_chars): Use ptrdiff_t, not int.
5110 * xterm.c (x_draw_underwave): Check for integer overflow.
5111 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

5298 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
5299 Use an inline function on all platforms when using the union type,
5300 since this is simpler and 'static inline' can be used portably

5411 * alloc.c (allocate_vectorlike): Fix last change.

5417 adjust comment accordingly.
5418 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

5444 * doprnt.c (doprnt): Truncate multibyte char correctly.
5445 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5446 would mishandle a string argument "Xc" if X was a multibyte
5447 character of length 2: it would truncate after X's first byte
5448 rather than including all of X.
5450 2012-06-06 Chong Yidong <cyd@gnu.org>

5477 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5478 (note_mode_line_or_margin_highlight): If there is no help echo,
5479 use mode-line-default-help-echo. Handle the case where the mouse
5480 position is past the end of the mode line string.
5482 * buffer.c (buffer_local_value_1): New function, split from
5483 Fbuffer_local_value; can return Qunbound.

5497 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
5499 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5501 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5502 Convert pctcpu and pctmem to Lisp float properly.
5503 Let the compiler fold better, as 100.0/0x8000 is exact.
5505 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5507 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
5510 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
5512 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
5514 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
5516 For a 'struct window', replace some Lisp_Object fields to
5517 bitfields where appropriate, remove unused fields.
5518 * window.h (struct window): Remove unused 'last_mark_x' and
5519 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
5520 change it's type from Lisp_Object to bitfield.
5521 Change type of 'force_start', 'optional_new_start',
5522 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
5523 fields from Lisp_Object to bitfield. Adjust users accordingly.
5525 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5527 Pacify gcc -Wdouble-precision when using Xaw.
5528 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
5529 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
5530 Use 'float' consistently, rather than 'float' in most places
5531 and 'double' in a couple of places.
5533 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5535 * xdisp.c (handle_stop): Detect whether we have overlay strings
5536 loaded by testing it->current.overlay_string_index to be
5537 non-negative, instead of checking whether n_overlay_strings is
5538 positive. (Bug#11587)
5540 2012-05-31 Chong Yidong <cyd@gnu.org>
5542 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
5544 * doc.c (Fsubstitute_command_keys): Doc fix.
5546 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5548 * search.c (search_buffer): Remove calls to
5549 r_alloc_inhibit_buffer_relocation, as it is now called by
5550 maybe_unify_char, which was the cause of relocation of buffer text
5553 2012-05-31 Eli Zaretskii <eliz@gnu.org>
5555 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
5556 for the duration of call to load_charset, to avoid problems with
5557 callers of maybe_unify_char that access buffer text through C
5560 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
5561 decrement the inhibition flag, instead of just setting or
5564 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
5566 Remove obsolete '#define static' cruft.
5567 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
5568 This #undef was "temporary" in 2000; it is no longer needed
5569 now that '#define static' has gone away.
5570 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
5571 (gray_bitmap_bits): Remove; no longer needed.
5572 All uses replaced with definiens.
5573 * xterm.c: Include "bitmaps/gray.xbm".
5575 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
5577 Clean up __executable_start, monstartup when --enable-profiling.
5578 The following changes affect the code only when profiling.
5579 * dispnew.c (__executable_start): Rename from safe_bcopy.
5580 Define only on platforms that need it.
5581 * emacs.c: Include <sys/gmon.h> when profiling.
5582 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
5583 (__executable_start): Remove decl, since lisp.h does it now.
5584 (safe_bcopy): Remove decl; no longer has that name.
5585 (main): Coalesce #if into single bit of code, for simplicity.
5586 Cast pointers to uintptr_t, since standard libraries want integers
5588 * lisp.h (__executable_start): New decl.
5590 2012-05-31 Glenn Morris <rgm@gnu.org>
5592 * image.c (Fimagemagick_types): Doc fix.

5611 * lread.c (read1): Tiny simplification.
5613 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
5615 Do not create empty overlays with the evaporate property (Bug#9642).
5616 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
5617 Bug#9642, but explicitly check that the buffer the overlay would
5618 be moved to is live and rearrange lines to make sure that errors
5619 will not put the overlay in an inconsistent state.
5620 (Fdelete_overlay): Cosmetics.
5622 2012-05-28 Eli Zaretskii <eliz@gnu.org>
5624 * w32term.c (my_bring_window_to_top): New function.
5625 (x_raise_frame): Use handle returned by DeferWindowPos, which
5626 could be different from the original one.
5627 Call my_bring_window_to_top instead of my_set_foreground_window.
5630 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
5631 by calling BringWindowToTop.
5633 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
5634 (WM_EMACS_END): Increase by one.
5636 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
5638 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
5639 This avoids undefined behavior that might cause the eassert
5640 to not catch an out-of-range value.
5642 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
5644 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
5645 Update dependencies.
5647 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5649 * bidi.c (bidi_mirror_char): Fix last change.
5651 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
5653 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
5654 when referring to sectname field in printf format.
5656 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
5658 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
5659 Only r_alloc_inhibit_buffer_relocation needed to be added;
5660 the others were already declared.
5662 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
5663 before checking whether it's out of range. Put the check inside
5665 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
5667 2012-05-27 Ken Brown <kbrown@cornell.edu>
5669 * callproc.c (Fcall_process): Restore a line that was accidentally
5670 commented out in the 2011-02-13 change (bug#11547).
5672 2012-05-27 Eli Zaretskii <eliz@gnu.org>
5674 * lisp.h [REL_ALLOC]: Add prototypes for external functions
5675 defined on ralloc.c.
5677 * buffer.c [REL_ALLOC]: Remove prototypes of
5678 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
5679 they are now on lisp.h.
5681 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
5683 * search.c (search_buffer): Use it to inhibit relocation of buffer
5684 text while re_search_2 is doing its job, because re_search_2 is
5685 passed C pointers to buffer text. (Bug#11519)
5687 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
5690 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
5691 state after an additional call to move_it_in_display_line_to, keep
5692 the values of it->max_ascent and it->max_descent found for the
5694 (pos_visible_p): Revert the comparison against bottom_y to what it
5695 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
5698 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5700 Fix coding-related core dumps with gcc -ftrapv.
5701 The code was computing A - B, where A and B are pointers, and B is
5702 random garbage. This can lead to core dumps on platforms that
5703 have special pointer registers, and it also leads to core dumps on
5704 x86-64 when compiled with gcc -ftrapv. The fix is to compute
5705 A - B only when B is initialized properly.
5706 * coding.c (coding_set_source, coding_set_destination): Return void.
5707 (coding_change_source, coding_change_destinations): New functions,
5708 with the old behaviors of coding_set_source and coding_set_destination.
5709 All callers that need an offset changed to use these new functions.
5711 2012-05-26 Glenn Morris <rgm@gnu.org>
5713 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
5715 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5717 Extend mouse support on W32 text-mode console.
5718 * xdisp.c (draw_row_with_mouse_face):
5719 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
5721 * w32console.c: Include window.h.
5722 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
5724 (initialize_w32_display): Initialize mouse-highlight data.
5726 * w32inevt.c: Include termchar.h and window.h.
5727 (do_mouse_event): Support mouse-autoselect-window. When the mouse
5728 moves, call note_mouse_highlight. If help_echo changed, call
5729 gen_help_event to produce help-echo message in the echo area.
5730 Call clear_mouse_face if mouse_face_hidden is set in the mouse
5733 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
5735 * lread.c (read1): Simplify slightly to avoid an overflow warning
5736 with GCC 4.7.0 on x86-64.
5738 2012-05-26 Eli Zaretskii <eliz@gnu.org>
5740 * bidi.c (bidi_mirror_char): Revert last change: an int is
5741 definitely wide enough here.
5743 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
5745 Fix integer width and related bugs (Bug#9874).
5746 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
5747 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
5748 (string_bytes, check_sblock, allocate_string_data):
5749 (compact_small_strings, Fmake_bool_vector, make_string)
5750 (make_unibyte_string, make_multibyte_string)
5751 (make_string_from_bytes, make_specified_string)
5752 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
5753 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
5755 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5756 (allocate_pseudovector):
5757 Use int, not EMACS_INT, where int is wide enough.
5758 (inhibit_garbage_collection, Fgarbage_collect):
5759 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5760 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
5761 int might not be wide enough.
5762 (bidi_cache_search, bidi_cache_find, bidi_init_it)
5763 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5764 (bidi_at_paragraph_end, bidi_find_paragraph_start)
5765 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
5766 (bidi_level_of_next_char, bidi_move_to_visually_next):
5767 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5768 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
5769 (Fkill_buffer, Fset_buffer_major_mode)
5770 (advance_to_char_boundary, Fbuffer_swap_text)
5771 (Fset_buffer_multibyte, overlays_at, overlays_in)
5772 (overlay_touches_p, struct sortvec, record_overlay_string)
5773 (overlay_strings, recenter_overlay_lists)
5774 (adjust_overlays_for_insert, adjust_overlays_for_delete)
5775 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
5776 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
5777 (Foverlay_recenter, last_overlay_modification_hooks_used)
5778 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
5779 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5780 (validate_region): Omit unnecessary test for b <= e,
5781 since that's guaranteed by the previous test.
5782 (adjust_overlays_for_delete): Avoid pos + length overflow.
5783 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
5784 (report_overlay_modification):
5785 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5786 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
5787 Omit pointer cast, which isn't needed anyway, and doesn't work
5788 after the EMACS_INT -> ptrdiff_t change.
5789 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
5790 * buffer.h: Adjust decls to match defn changes elsewhere.
5791 (struct buffer_text, struct buffer):
5792 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5793 Use EMACS_INT, not int, where int might not be wide enough.
5794 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
5795 not int, to avoid needless 32-bit limit on 64-bit hosts.
5796 (exec_byte_code): Use tighter memory-full test, one that checks
5797 for alloca overflow. Don't compute the address of the object just
5798 before an array, as that's not portable. Use EMACS_INT, not
5799 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
5800 * callint.c (Fcall_interactively):
5801 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5802 * callproc.c (call_process_kill, Fcall_process):
5803 Don't assume pid_t fits into an Emacs fixnum.
5804 (call_process_cleanup, Fcall_process, child_setup):
5805 Don't assume pid_t fits into int.
5806 (call_process_cleanup, Fcall_process, delete_temp_file)
5807 (Fcall_process_region):
5808 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5809 (Fcall_process): Simplify handling of volatile integers.
5810 Use int, not EMACS_INT, where int will do.
5811 * casefiddle.c (casify_object, casify_region, operate_on_word)
5812 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
5813 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5814 (casify_object): Avoid integer overflow when overallocating buffer.
5815 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
5816 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
5817 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
5818 * category.h (CATEGORYP): Don't assume arg is nonnegative.
5819 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
5820 integers are now checked earlier. All uses replaced with XINT.
5822 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5823 For CCL_MapSingle, check that content and value are in int range.
5824 (ccl_driver, Fregister_code_conversion_map):
5825 Check that Vcode_version_map_vector is a vector.
5826 (resolve_symbol_ccl_program): Check that vector header is in range.
5827 Always copy the vector, so that we can check its contents reliably
5828 now rather than having to recheck each instruction as it's being
5829 executed. Check that vector words fit in 'int'.
5830 (ccl_get_compiled_code, Fregister_ccl_program)
5831 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
5832 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
5833 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
5834 contents are in range.
5835 (Fccl_execute_on_string): Check that status is in range.
5836 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
5837 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
5838 Accept and return EMACS_INT, not int, because callers can pass values
5840 (c_string_width, strwidth, lisp_string_width, chars_in_text)
5841 (multibyte_chars_in_text, parse_str_as_multibyte)
5842 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
5843 (str_as_unibyte, str_to_unibyte, string_count_byte8)
5844 (string_escape_byte8, Fget_byte):
5845 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5846 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
5847 avoid mishandling large integers.
5848 * character.h: Adjust decls to match defn changes elsewhere.
5849 * charset.c (load_charset_map_from_file, find_charsets_in_text)
5850 (Ffind_charset_region):
5851 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
5852 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
5853 (load_charset_map_from_vector, Fdefine_charset_internal):
5854 Don't assume fixnum fits in int.
5855 (load_charset_map_from_vector, Fmap_charset_chars):
5856 Remove now-unnecessary CHECK_NATNUMs.
5857 (Fdefine_charset_internal): Check ranges here, more carefully.
5858 Don't rely on undefined behavior with signed left shift overflow.
5859 Don't assume unsigned int fits into fixnum, or that fixnum fits
5860 into unsigned int. Don't require max_code to be a valid fixnum;
5861 that's not true for gb10830 4-byte on a 32-bit host. Allow
5862 invalid_code to be a cons, for the same reason. Require code_offset
5863 to be a character. Avoid int overflow if max_char is close
5865 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
5866 this is intended anyway and avoids some undefined behavior.
5867 (load_charset_map): Pass unsigned, not int, as 2nd arg of
5868 INDEX_TO_CODE_POINT, as that's what it expects.
5869 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
5870 * charset.h (DECODE_CHAR): Return int, not unsigned;
5871 this is what was intended anyway, and it avoids undefined behavior.
5872 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
5873 integer-overflow issues.
5874 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
5875 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
5876 where the argument is EMACS_INT, and this behavior is not intended.
5877 * chartab.c (Fmake_char_table, Fset_char_table_range)
5878 (uniprop_get_decoder, uniprop_get_encoder):
5879 Don't assume fixnum fits in int.
5880 * cmds.c (move_point): New function, that does the gist of
5881 Fforward_char and Fbackward_char, but does so while checking
5882 for integer overflow more accurately.
5883 (Fforward_char, Fbackward_char): Use it.
5884 (Fforward_line, Fend_of_line, internal_self_insert)
5885 (internal_self_insert):
5886 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
5887 Fix a FIXME, by checking for integer overflow when calculating
5888 target_clm and actual_clm.

6598 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
6599 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
6601 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
6603 Assume C89 or later.
6604 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
6605 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
6607 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
6608 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
6609 * textprop.c, tparam.c (NULL): Remove.
6610 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
6611 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
6612 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
6613 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
6614 * xterm.c (input_signal_count): Assume volatile works.
6616 2012-05-21 Ken Brown <kbrown@cornell.edu>
6618 * xgselect.c (xg_select): Fix first argument in call to 'select'
6621 2012-05-20 Ken Brown <kbrown@cornell.edu>
6623 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
6624 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
6626 2012-05-19 Ken Brown <kbrown@cornell.edu>
6628 * xfns.c (x_in_use): Remove `static' qualifier.
6629 * xterm.h (x_in_use): Declare.
6630 * xgselect.c: Include xterm.h.
6631 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
6632 and `display_arg' (bug#9754).
6634 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
6636 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
6638 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
6639 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
6641 2012-05-18 Eli Zaretskii <eliz@gnu.org>
6643 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
6645 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
6646 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
6648 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
6649 reference to image_cache->refcount.
6650 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
6652 2012-05-17 Juri Linkov <juri@jurta.org>
6654 * search.c (Fword_search_regexp, Fword_search_backward)
6655 (Fword_search_forward, Fword_search_backward_lax)
6656 (Fword_search_forward_lax): Move functions to isearch.el
6657 (bug#10145, bug#11381).
6659 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
6661 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
6663 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
6665 * lread.c (init_obarray): Declare Qt and Qnil as special.
6667 2012-05-14 Glenn Morris <rgm@gnu.org>
6669 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
6670 Put "libexec" before "bin", for the sake of init_callproc_1.
6672 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6674 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
6676 * unexaix.c: Port to more-recent AIX compilers.
6677 (report_error, report_error_1, make_hdr, copy_sym)
6678 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
6679 Make arguments const char *, not char *, to avoid violations of C
6680 standard and to fix some AIX warnings reported by Gilles Pion.
6682 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6684 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
6685 already have overlays loaded.
6686 (handle_single_display_spec): Before returning without displaying
6687 fringe bitmap, synchronize the bidi iterator with the main display
6688 iterator, by calling iterate_out_of_display_property.
6689 (iterate_out_of_display_property): Detect buffer iteration by
6690 testing that it->string is a Lisp string.
6691 (get_next_display_element): When the current object is exhausted,
6692 and there's something on it->stack, call set_iterator_to_next to
6693 proceed with what's on the stack, instead of returning zero.
6694 (set_iterator_to_next): If called at the end of a Lisp string,
6695 proceed to consider_string_end without incrementing string
6696 position. Don't increment display vector index past the end of
6697 the display vector. (Bug#11417)
6698 (pos_visible_p): Don't report a position visible when move_it_to
6699 stopped at the last line of window, which happens to be scanned
6700 backwards by the bidi iteration. (Bug#11464)
6702 2012-05-14 Eli Zaretskii <eliz@gnu.org>
6704 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
6705 and right-margin display specs even if the spec is invalid or we
6706 are on a TTY, and thus unable to display on the fringes.
6707 That's because the text with the property will not be displayed anyway,
6708 so we need to signal to the caller that this is a "replacing"
6709 display spec. This fixes display when the spec is invalid or we
6712 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
6714 * unexaix.c (make_hdr): Fix typo in prototype.
6715 This bug broke the build on AIX. Problem reported by Gilles Pion.
6717 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
6719 * keyboard.c (kbd_buffer_get_event): Read special events also in
6720 batch mode. (Bug#11415)
6722 2012-05-12 Glenn Morris <rgm@gnu.org>
6724 * ns.mk: Update for ns_appbindir no longer having trailing "/".
6726 2012-05-12 Eli Zaretskii <eliz@gnu.org>
6728 * lisp.mk (lisp): Add newcomment.elc.
6730 2012-05-12 Glenn Morris <rgm@gnu.org>
6732 * Makefile.in (MKDIR_P): New, set by configure.
6733 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
6735 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
6737 Remove unused function hourglass_started.
6738 * dispextern.h (hourglass_started):
6739 * w32fns.c (hourglass_started):
6740 * xdisp.c (hourglass_started): Remove.
6742 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
6744 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
6745 Update dependencies.
6747 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
6749 * xgselect.c (xg_select): Put maxfds+1 into a var.
6750 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
6752 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
6754 2012-05-10 Dave Abrahams <dave@boostpro.com>
6756 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
6757 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
6759 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
6761 * dbusbind.c (xd_registered_buses): New internal Lisp object.
6762 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
6763 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
6764 Initialize xd_registered_buses.
6766 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
6768 Untag more efficiently if USE_LSB_TAG.
6769 This is based on a proposal by YAMAMOTO Mitsuharu in
6770 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
6771 For an admittedly artificial (nth 8000 longlist) benchmark on
6772 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
6773 Emacs's overall text size by 1%.
6774 * lisp.h (XUNTAG): New macro.
6775 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
6776 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
6777 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
6778 * eval.c (Fautoload):
6779 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
6780 * frame.h (XFRAME): Use XUNTAG.
6782 Port recent dbusbind.c changes to 32-bit --with-wide-int.
6783 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
6784 Remove unportable assumptions about print widths of types like
6786 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
6787 intptr_t when converting between pointer and integer, to avoid GCC
6788 warnings about wrong width.
6790 2012-05-09 Eli Zaretskii <eliz@gnu.org>
6792 * w32proc.c (new_child): Force Windows to reserve only 64KB of
6793 stack for each reader_thread, instead of defaulting to 8MB
6794 determined by the linker. This avoids failures in creating
6795 subprocesses on Windows 7, see the discussion in this thread:
6796 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
6798 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
6800 Fix up display of the *Minibuf-0* buffer in the mini window.
6801 * keyboard.c (read_char): Don't clear the echo area if there's no
6803 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
6804 contents of *Minibuf-0*) if there's no message displayed in its stead.
6806 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
6808 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
6811 2012-05-06 Chong Yidong <cyd@gnu.org>
6813 * lisp.mk (lisp): Update.
6815 2012-05-05 Jim Meyering <meyering@redhat.com>
6817 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
6819 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
6821 * data.c (PUT_ERROR): New macro.
6822 (syms_of_data): Use it. Add new error type `user-error'.
6823 * undo.c (user_error): New function.
6824 (Fprimitive_undo): Use it.
6825 * print.c (print_error_message): Adjust print style for `user-error'.
6826 * keyboard.c (user_error): New function.
6827 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
6829 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
6831 Do not limit current-time-string to years 1000..9999.
6832 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
6833 (Fcurrent_time_string): Support any year that is supported by the
6834 underlying localtime representation. Don't use asctime, as it
6835 has undefined behavior for years outside the range -999..9999.
6837 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
6839 Fix race conditions involving setenv, gmtime, localtime, asctime.
6840 Without this fix, interrupts could mess up code that uses these
6841 nonreentrant functions, since setting TZ invalidates existing
6842 tm_zone or tzname values, and since most of these functions return
6843 pointers to static storage.
6844 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
6845 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
6846 Grow the critical sections to include not just invoking
6847 localtime/gmtime, but also accessing these functions' results
6848 including their tm_zone values if any, and any related TZ setting.
6849 (format_time_string): Last arg is now struct tm *, not struct tm **,
6850 so that the struct tm is saved in the critical section.
6851 All callers changed. Simplify allocation of initial buffer, partly
6852 motivated by the fact that memory allocation needs to be outside
6853 the critical section.
6855 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
6857 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
6858 with RESET_INTERVAL.
6860 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
6861 Remove duplicated buffer name initialization.
6863 2012-05-02 Jim Meyering <jim@meyering.net>
6865 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
6867 * xfns.c (x_window): Use xstrdup (Bug#11375).
6869 2012-05-02 Eli Zaretskii <eliz@gnu.org>
6871 * xdisp.c (pos_visible_p): If already at a newline from the
6872 display string before the 'while' loop, don't walk back the glyphs
6873 from it3.glyph_row. Solves assertion violation when the display
6874 string begins with a newline (egg.el). (Bug#11367)
6876 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
6878 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
6881 2012-05-01 Glenn Morris <rgm@gnu.org>
6883 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
6884 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
6885 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
6886 All were removed before 23.1.
6888 * dispnew.c: Remove HAVE_LIBNCURSES test;
6889 it is always true on relevant platforms.
6891 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
6892 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
6894 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
6896 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
6898 * .gdbinit (xpr): Remove checks for no longer existing misc types.
6899 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
6902 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
6904 Do not avoid creating empty evaporating overlays (Bug#9642).
6905 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
6906 That is, do not delete an evaporating overlay if it becomes
6907 empty after its bounds are adjusted to fit within its buffer.
6908 This fix caused other problems, and I'm reverting it until we get
6909 to the bottom of them.
6911 2012-04-27 Chong Yidong <cyd@gnu.org>
6913 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
6915 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6917 * xdisp.c (pos_visible_p): If the window start position is beyond
6918 ZV, start the display from buffer beginning. Prevents assertion
6919 violation in init_iterator when the minibuffer window is scrolled
6922 * window.c (window_scroll_pixel_based): Likewise.
6924 2012-04-27 Chong Yidong <cyd@gnu.org>
6926 * keymap.c (where_is_internal): Doc fix (Bug#10872).
6928 2012-04-27 Glenn Morris <rgm@gnu.org>
6930 * fileio.c (Fcopy_file, Fset_file_selinux_context):
6931 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
6933 2012-04-27 Eli Zaretskii <eliz@gnu.org>
6935 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
6936 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
6938 2012-04-26 Eli Zaretskii <eliz@gnu.org>
6940 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
6941 display element, check also the underlying string or buffer
6942 character. (Bug#11341)
6944 * w32menu.c: Include w32heap.h.
6945 (add_menu_item): If the call to AppendMenuW (via
6946 unicode_append_menu) fails, disable Unicode menus only if we are
6947 running on Windows 9X/Me.
6949 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
6951 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
6952 (xgetint): Add missing shift for LSB tags.
6954 2012-04-24 Martin Rudalics <rudalics@gmx.at>
6956 * keyboard.c (read_char): Don't wipe echo area for select window
6957 events: These might get delayed via `mouse-autoselect-window'
6960 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
6962 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
6963 manipulation of :loaded-from data.
6965 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
6967 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
6968 now a cons (bug#11311).
6970 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
6972 Do not create empty overlays with the evaporate property (Bug#9642).
6973 * buffer.c (Fmove_overlay): Delete an evaporating overlay
6974 if it becomes empty after its bounds are adjusted to fit within
6975 its buffer. Without this fix, in a nonempty buffer (let ((o
6976 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
6977 yields an empty overlay that has the evaporate property, which is
6978 not supposed to happen.
6980 Fix minor GTK3 problems found by static checking.
6981 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
6982 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6983 (struct _EmacsFixedClass, emacs_fixed_get_type):
6984 Move decls here from emacsgtkfixed.h, since they needn't be public.
6985 (emacs_fixed_get_type): Now static.
6986 (emacs_fixed_class_init): Omit unused local.
6987 (emacs_fixed_child_type): Remove; unused.

6989 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6990 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
6991 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
6992 (EMACS_FIXED_GET_CLASS): Remove; unused.
6993 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
6995 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
6996 Problem reported by Juanma Barranquero for Windows -Wunused-function.
6998 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7000 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7001 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7002 (__malloc_size_t, __malloc_ptrdiff_t):
7003 Remove. All uses removed, replaced by the definiens if needed,
7004 since we can assume C89 or better now.
7005 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7006 (protect_malloc_state, align, get_contiguous_space)
7007 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
7008 (malloc_atfork_handler_child, malloc_enable_thread)

7013 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7014 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7015 Define using prototypes, not old style.
7016 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7017 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
7018 (align): Don't assume that signed integer overflow wraps around.
7019 Omit unused local var.
7020 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
7021 (_free_internal_nolock, memalign, mallochook, reallochook):
7022 Omit no-longer-needed casts.
7023 (valloc): Use getpagesize, not __getpagesize.
7024 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
7025 (struct hdr): The 'magic' member is now size_t, not unsigned long.
7027 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
7029 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
7031 Move functions from C to Lisp. Make non-blocking method calls
7032 the default. Implement further D-Bus standard interfaces.
7034 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
7035 (QCdbus_request_name_allow_replacement)
7036 (QCdbus_request_name_replace_existing)
7037 (QCdbus_request_name_do_not_queue)

7041 (QCdbus_request_name_reply_already_owner): Move to dbus.el.
7042 (QCdbus_registered_serial, QCdbus_registered_method)
7043 (QCdbus_registered_signal): New Lisp objects.
7044 (XD_DEBUG_MESSAGE): Use sizeof.

7046 (XD_DBUS_VALIDATE_BUS_ADDRESS, XD_DBUS_VALIDATE_OBJECT)
7047 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)

7078 Do not assume ptrdiff_t is the same width as 'int'.
7080 * alloc.c: Handle unusual debugging option combinations.
7081 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7082 since the two debugging options are incompatible.
7083 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7085 (mem_init, mem_insert, mem_insert_fixup):
7086 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7116 * print.c (print_preprocess): Only check print_depth if print-circle
7118 (print_object): Check for cycles even when print-circle is nil and
7119 print-gensym is t, but only check print_depth if print-circle is nil.
7121 2012-04-20 Chong Yidong <cyd@gnu.org>
7123 * process.c (wait_reading_process_output): If EIO occurs on a pty,

7179 New extern decls, to avoid calling undeclared functions.
7180 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7181 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7182 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

7204 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
7206 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

7223 Remove definition of GC_MARK_STACK, since the default now works.
7224 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7225 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
7226 no longer the default.
7227 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7229 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
7231 * lread.c (lisp_file_lexically_bound_p):

7252 2012-04-11 Daniel Colascione <dancol@dancol.org>
7254 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7255 against is gone. It's better to use vfork now so that when Cygwin
7256 gains a new, working vfork, we use it automatically (bug#10398).
7258 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

7279 being loaded (bug#10424).
7281 2012-04-09 Glenn Morris <rgm@gnu.org>
7283 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7284 not just in the obarray, before snarfing them. (Bug#11036)
7286 * Makefile.in ($(leimdir)/leim-list.el):

7311 * minibuf.c (Fread_variable): Callers changed.
7313 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7315 * xdisp.c (set_cursor_from_row): If the display string appears in
7316 the buffer at position that is closer to point than the position
7317 after the display string, display the cursor on the first glyph of
7318 the display string. Fixes cursor display when a 'display' text
7319 property immediately follows invisible text. (Bug#11094)
7321 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7323 composite.c: use 'double' consistently
7324 * composite.c (get_composition_id): Use 'double' consistently
7325 instead of converting 'float' to 'double' and vice versa; this is
7326 easier to understand and avoids a GCC warning.
7328 2012-04-09 Glenn Morris <rgm@gnu.org>
7330 * Makefile.in: Generate leim-list with bootstrap-emacs, in
7331 preparation for dumping it with emacs. (Bug#4789)

7353 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7354 (mark_memory): Mark Lisp_Objects only if pointers might hide in

7373 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
7374 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7375 [!WINDOWSNT]: New macros.
7376 (init_libxml2_functions, libxml2_loaded_p): New functions.
7377 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7378 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7379 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7380 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7382 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7383 Call init_libxml2_functions before calling libxml2 functions.
7384 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7386 * emacs.c: Don't include libxml/parser.h.

7388 xmlCleanupParser directly.
7390 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7392 2012-04-07 Eli Zaretskii <eliz@gnu.org>

7400 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7401 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7402 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7403 macros related to unification of CJK characters. For the details,
7404 see the discussion following the message here:
7405 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7407 2012-04-04 Chong Yidong <cyd@gnu.org>
7409 * keyboard.c (Vdelayed_warnings_list): Doc fix.

7421 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7423 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7424 position we get to after a call to move_it_to fails the
7425 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7426 only if we wind up in a string from display property. (Bug#11063)
7428 * window.c (Fdelete_other_windows_internal): Invalidate the row
7429 and column information about mouse highlight, so that redisplay
7430 restores it after reallocating the glyph matrices. (Bug#7464)
7432 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7433 string comes from a `display' text property, use the buffer
7434 position of that property as if we actually saw that position in
7436 (move_it_by_lines): Remove the assertion that
7437 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7438 violated when there's a before-string at the beginning of a line.
7441 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7443 * xdisp.c (append_space_for_newline): If the default face was
7444 remapped, use the remapped face for the appended newline.
7445 (extend_face_to_end_of_line): Use the remapped default face for
7446 extending the face to the end of the line.
7447 (display_line): Call extend_face_to_end_of_line when the default
7448 face was remapped. (Bug#11068)
7450 2012-03-29 Eli Zaretskii <eliz@gnu.org>

7472 handle-select-window too (Bug#8996).
7474 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7476 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

7481 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7483 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7485 * s/ms-w32.h (tzname): Include time.h before redirecting to

7496 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7498 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7499 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7500 when fetching a multibyte character consumes more bytes than
7501 CHAR_BYTES returns, due to unification of CJK characters in
7502 string_char. (Bug#11073)
7504 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7506 * process.c (wait_reading_process_output): Handle pty disconnect
7507 by refraining from sending oneself a SIGCHLD (bug#10933).

7524 * w32proc.c (Fw32_set_console_codepage)
7525 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
7528 2012-03-20 Chong Yidong <cyd@gnu.org>
7530 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
7531 to reflect default non-nil value of redisplay-dont-pause.
7533 2012-03-19 Kenichi Handa <handa@m17n.org>
7535 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
7536 it fit in a valid range (Bug#11003).
7538 2012-03-18 Eli Zaretskii <eliz@gnu.org>
7540 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
7541 that is not from display property, accept the row as a "cursor
7542 row" if one of the string's character has a non-nil `cursor'
7543 property. Fixes cursor positioning when there are newlines in
7544 overlay strings, e.g. in icomplete.el. (Bug#11035)
7546 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

7577 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
7580 2012-03-03 Glenn Morris <rgm@gnu.org>
7582 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

7590 (redisplay_window): Pass to move_it_vertically the margin in
7591 pixels, not in screen lines.
7593 2012-03-02 Glenn Morris <rgm@gnu.org>
7595 * buffer.c (buffer-list-update-hook): Doc fix.
7597 2012-02-29 Eli Zaretskii <eliz@gnu.org>

7600 push_it before setting up the iterator for the first overlay
7601 string, even if we have an empty string loaded.
7602 (next_overlay_string): If there's an empty string on the iterator
7603 stack, pop the stack. (Bug#10903)
7605 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
7607 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
7608 Suggested by Stefan Monnier in
7609 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
7610 * alloc.c (widen_to_Lisp_Object): New static function.
7611 (mark_memory): Also mark Lisp_Objects by fetching pointer words
7612 and widening them to Lisp_Objects. This would work even if
7613 USE_LSB_TAG is defined and wide integers are used, which might
7614 happen in a future version of Emacs.
7616 2012-02-25 Chong Yidong <cyd@gnu.org>
7618 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

7623 before saving to clipboard manager.
7625 2012-02-24 Chong Yidong <cyd@gnu.org>
7627 * keyboard.c (process_special_events): Handle all X selection
7628 requests in kbd_buffer, not just the next one (Bug#8869).
7630 2012-02-23 Chong Yidong <cyd@gnu.org>
7632 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
7633 call when setting menu-bar-lines and tool-bar-lines parameters.
7634 (unwind_create_frame_1): New helper function.
7636 * window.c (inhibit_window_configuration_change_hook): New var.
7637 (run_window_configuration_change_hook): Obey it.
7638 (syms_of_window): Initialize it.
7640 2012-02-22 Chong Yidong <cyd@gnu.org>
7642 * xterm.c (x_draw_image_relief): Add missing type check for

7654 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
7655 when computing $valmask.
7657 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
7658 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
7659 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
7660 It's useless in that case, and it can cause problems on hosts
7661 that allocate halves of EMACS_INT values separately.
7662 Reported by Dan Horák. Diagnosed by Andreas Schwab in
7663 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
7664 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
7665 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
7666 it avoids undefined behavior on hosts where shifting right by more
7667 than the word width has undefined behavior.
7669 2012-02-19 Chong Yidong <cyd@gnu.org>
7671 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
7672 (Funhandled_file_name_directory, Ffile_name_as_directory)
7673 (Fdirectory_file_name, Fexpand_file_name)

7691 2012-02-15 Chong Yidong <cyd@gnu.org>
7693 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
7694 marked as special. Also, starting docstrings with * is obsolete.
7696 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>

7709 2012-02-12 Chong Yidong <cyd@gnu.org>
7711 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
7712 as that creates a dangerous corner case.
7714 * window.c (Fdelete_window_internal): Invalidate the mouse
7715 highlight (Bug#9904).
7717 2012-02-12 Glenn Morris <rgm@gnu.org>

7722 * nsselect.m (Fx_own_selection_internal)
7723 (Fx_disown_selection_internal, Fx_selection_exists_p)
7724 (Fx_selection_owner_p, Fx_get_selection_internal):
7725 Sync docs and argument specs with the xselect.c versions.

7747 2012-02-07 Chong Yidong <cyd@gnu.org>
7749 * buffer.c (Fbuffer_local_variables)
7750 (buffer_lisp_local_variables): Handle unbound vars correctly;
7751 don't let Qunbound leak into Lisp.
7753 2012-02-07 Glenn Morris <rgm@gnu.org>
7755 * image.c (Fimagemagick_types): Doc fix.
7757 * image.c (imagemagick-render-type): Change it from a lisp object
7758 to an integer. Move the doc here from the lisp manual.

7763 * doc.c (store_function_docstring): Avoid applying docstring of
7764 alias to base function (Bug#2603).

7788 before BEGV. (Bug#10696)
7790 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
7792 Handle overflow when computing char display width (Bug#9496).
7793 * character.c (char_width): Return EMACS_INT, not int.
7794 (char_width, c_string_width): Check for overflow when
7795 computing the width; this is possible now that individual
7796 characters can have unbounded width. Problem introduced
7797 by merge from Emacs 23 on 2012-01-19.
7799 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

7828 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
7829 first 2 arguments are identical. This makes inserting large
7830 output from a subprocess an order of magnitude faster on
7831 MS-Windows, where all sbrk'ed memory is always contiguous.

7935 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
7937 emacs: fix an auto-save permissions race condition (Bug#10400)
7938 * fileio.c (auto_saving_dir_umask): New static var.
7939 (Fmake_directory_internal): Use it.
7940 (do_auto_save_make_dir): Set it, instead of invoking chmod after
7941 creating the directory. The old code temporarily assigns
7942 too-generous permissions to the directory.
7943 (do_auto_save_eh): Clear it.
7944 (Fdo_auto_save): Catch all errors, not just file errors, so
7945 that the var is always cleared.

8002 * xdisp.c (handle_invisible_prop): Handle correctly an invisible
8003 property that ends at ZV, so that the bidi iteration could be

8451 is set, removing the need for VIRT_ADDRESS_VARIES.
8452 (PURE_P): Use a more-efficient implementation that needs just one

8469 behave as if the cursor position were at the window margin.
8471 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8472 and the cursor position is out of bounds, behave as if the cursor
8473 position were at the window margin. (Bug#10075)

8503 * dispnew.c (verify_row_hash): Call row_hash for computing the
8504 hash code of a row, instead of duplicating code from xdisp.c.
8506 * dispextern.h (row_hash): Add prototype.
8508 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
8510 * frame.c (delete_frame): Don't delete the terminal when the last

8725 (Fwindow_vscroll): Doc fix.

8990 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
8992 * keyboard.c (test_undefined): New function (bug#9751).
8993 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
8995 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
8997 * sysdep.c (init_sys_modes): Fix the check for the controlling
8998 terminal (Bug#6649).
9000 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9002 * dispextern.h (struct bidi_it): New member next_en_type.
9004 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9005 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9006 current character, check also for next_en_type being WEAK_EN.
9007 (bidi_resolve_weak): Don't enter the expensive loop if the current
9008 position is before next_en_pos. Record the bidi type of the first
9009 non-ET, non-BN character we find, in addition to its position.
9010 (bidi_level_of_next_char): Invalidate next_en_type when
9011 next_en_pos is over-stepped.
9013 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9015 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9016 * editfns.c: Rewrite current-time-zone so that it invokes
9017 the equivalent of (format-time-string "%Z") to get the time zone name.
9018 This fixes a bug when the time zone name contains characters that
9019 need converting from the system time locale to Emacs internal format.
9020 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9021 that patch fixed format-time-string to do the conversion, but
9022 I forgot to fix current-time-zone.
9023 (format_time_string): New function, containing most of
9024 what Fformat_time_string used to contain.
9025 (Fformat_time_string): Rewrite in terms of format_time_string.
9026 This doesn't change this function's behavior.
9027 (current-time-zone): Rewrite to use format_time_string.
9028 This fixes the bug reported by Michael Schierl in
9029 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9030 Jason Rumney's 2007-06-07 change worked around this bug, but
9032 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9034 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9036 * xdisp.c (start_display): If the character at POS is displayed
9037 via a display vector, reset IT->current.dpvec_index to zero.
9038 (try_window_reusing_current_matrix): If a line ends in a display
9039 vector or the next line starts in a display vector, continue
9040 redrawing the window even though the character position of
9041 start_row was reached.
9044 2011-10-18 Chong Yidong <cyd@gnu.org>
9046 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9047 with nobreak-char-display too.
9049 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9051 Fix part 3 of bug#9771.
9052 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9053 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9054 non-neutral characters if the current character is a paragraph
9055 separator (a.k.a. Newline). This avoids running the same
9056 expensive loop twice, once when we consume the preceding newline
9057 and the other time when the line actually needs to be displayed.
9058 Avoid the loop when we see neutrals on the base embedding level
9059 following a character whose directionality is the same as the
9060 paragraph's. This avoids running the expensive loop when a line
9061 ends in a long sequence of neutrals, like control characters.
9062 Add assertion against STRONG_AL type. Slightly rearrange code
9063 that determines the type of a neutral given the first non-neutral
9065 (bidi_level_of_next_char): Set next_en_pos to zero when
9066 invalidating its info.
9068 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9070 * xdisp.c (push_display_prop): Determine whether to record string
9071 or buffer position by IT->string, not by IT->method. Allow
9072 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9073 (move_it_vertically_backward): Don't look for character position
9074 immediately after the newline when in a continuation line.
9077 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9079 * window.c (coordinates_in_window): Rewrite and delabelize
9080 vertical border check. (Bug#5357) (Bug#9618)
9082 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9084 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9085 errors in XSetWindowBorder (bug#9310).
9087 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9089 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9090 avoid crash when xmalloc overrun checking is enabled.
9092 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9094 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9095 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9096 cursor motion with <left> and <right> arrow keys.
9098 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9099 some callers set that themselves.
9101 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9103 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9104 display string and the previous row comes from the same string and
9105 is empty. (Bug#9739) (Bug#9738)
9107 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9109 * doc.c (get_doc_string): Encode file name (bug#9735).
9111 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9113 * bidi.c (bidi_level_of_next_char):
9114 * xdisp.c (get_visually_first_element): Remove old incorrect
9115 comments regarding the Unicode Line Separator character.
9117 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9119 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9121 * alloc.c (Fgc_status): Do not access beyond zombies array
9122 boundary if nzombies > MAX_ZOMBIES.
9123 * alloc.c (dump_zombies): Add missing format specifier.
9125 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9127 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9128 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9130 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9131 Some packages use them to denote characters with modifiers.
9133 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9135 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9136 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9137 matching a pp-number. Rename parameter var to var1.
9139 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9141 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9143 2011-10-08 Glenn Morris <rgm@gnu.org>
9145 * callint.c (Fcall_interactively): Give a more explicit error for the
9146 'c' case with a non-character input. (Bug#8479)
9148 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9150 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9152 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9153 lines that are hscrolled on the left.
9155 * dispnew.c (buffer_posn_from_coords): Account for a possible
9156 presence of header-line. (Bug#4426)
9158 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9160 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9161 Don't advertise functionality which we discourage or doesn't work.
9163 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9165 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9166 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9167 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9168 this makes Emacs dump core during garbage collection on rare
9169 occasions. sizeof is obviously inferior to offsetof here, so
9170 stick with offsetof.
9171 (GC_POINTER_ALIGNMENT): New macro.
9172 (mark_memory): Omit 3rd (offset) arg; caller changed.
9173 Don't assume EMACS_INT alignment is the same as pointer alignment.
9175 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9177 * keyboard.c (read_key_sequence_remapped): New var.
9178 (read_key_sequence): Compute remapping in the right buffer.
9179 (command_loop_1): Use read_key_sequence's remapping directly.
9181 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9183 * dired.c (file_name_completion): Don't expand file name.
9184 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9185 before checking file name handler.
9187 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9188 they've been requested explicitly (bug#9591).
9190 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9192 * keymap.c (Fsingle_key_description): Use make_specified_string
9193 instead of build_string to build string from push_key_description.
9196 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9198 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9199 This fixes a Y2038 bug on 64-bit hosts.
9200 * buffer.c (reset_buffer):
9201 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9202 (Fclear_buffer_auto_save_failure):
9203 Use 0, not -1, to represent an unset failure time, since time_t
9204 might not be signed.
9206 Remove dependency on glibc malloc internals.
9207 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9208 Move back here from lisp.h, but with their new implementations.
9209 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9210 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9211 * charset.c (charset_table_init): New static var.
9212 (syms_of_charset): Use it instead of xmalloc. This removes a
9213 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9214 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9215 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9216 Move back to alloc.c.
9217 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9218 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9220 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9222 * nsterm.m (windowDidResize): Call x_set_window_size only when
9223 ns_in_resize is true. Otherwise set pixelwidth/height and
9224 call change_frame_size (Bug#9628).
9226 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9228 Port --enable-checking=all to Fedora 14 x86-64.
9229 * charset.c (syms_of_charset): Also account for glibc malloc's
9230 internal overhead when calculating the initial malloc maximum.
9232 Port --enable-checking=all to Fedora 14 x86.
9233 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9235 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9236 (overrun_check_realloc, overrun_check_free):
9237 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9238 That way, xmalloc returns a properly-aligned pointer even if
9239 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9240 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9241 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9242 into account when calculating the initial malloc maximum.
9243 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9244 Move here from alloc.c, so that charset.c can use it too.
9245 Properly align; the old code wasn't right for common 32-bit hosts
9246 when configured with --enable-checking=all.
9247 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9248 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9250 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9252 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
9255 2011-09-28 Eli Zaretskii <eliz@gnu.org>
9257 * xdisp.c (compute_display_string_end): If there's no display
9258 string at CHARPOS, return -1.
9260 * bidi.c (bidi_fetch_char): When compute_display_string_end
9261 returns a negative value, treat the character as a normal
9262 character not covered by a display string. (Bug#9624)
9264 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
9266 * lread.c (Fread_from_string): Fix typo in docstring.
9268 2011-09-27 Eli Zaretskii <eliz@gnu.org>
9270 * xdisp.c (handle_invisible_prop): If invisible text ends on a
9271 newline, reseat the iterator instead of bidi-iterating there one
9272 character at a time. (Bug#9610)
9273 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9274 TO_CHARPOS if the bidi iterator is at base embedding level.
9276 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
9278 * lread.c (readevalloop): Use correct code for NBSP.
9279 (read1): Likewise. (Bug#9608)
9281 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
9283 * dbusbind.c (Fdbus_register_signal): When service is not
9284 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
9286 2011-09-25 Glenn Morris <rgm@gnu.org>
9288 * buffer.c (truncate-lines): Doc fix.
9290 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
9292 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
9293 (Fset_window_next_buffers): Doc fix.
9295 2011-09-24 Glenn Morris <rgm@gnu.org>
9297 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
9299 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
9301 Fix minor problems found by static checking.
9302 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
9303 * indent.c (Fvertical_motion): Fix == vs = typo.
9305 2011-09-24 Eli Zaretskii <eliz@gnu.org>
9307 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
9308 Default value is now t. Doc fix.
9310 * indent.c (Fvertical_motion): Compute and apply the overshoot
9311 logic when moving up, not only when moving down. Fix the
9312 confusing name and values of the it_overshoot_expected variable;
9313 logic changes accordingly. (Bug#9254) (Bug#9549)
9315 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
9316 CHARPOS is covered by a display string which includes newlines.
9317 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
9318 is covered by a display string with embedded newlines.
9320 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
9322 * dbusbind.c (Fdbus_register_signal): Add match rule to
9323 Vdbus_registered_objects_table. (Bug#9581)
9324 (Fdbus_register_method, Vdbus_registered_objects_table):
9327 2011-09-24 Jim Meyering <meyering@redhat.com>
9329 do not ignore write error for any output size
9330 The previous change was incomplete.
9331 While it makes emacs --batch detect the vast majority of stdout
9332 write failures, errors were still ignored whenever the output size is
9333 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9334 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9335 && echo FAIL: ignored write error
9336 FAIL: ignored write error
9337 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9338 && echo FAIL: ignored write error
9339 FAIL: ignored write error
9340 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9342 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
9344 * emacs.c (Fkill_emacs): In noninteractive mode exit
9345 non-successfully if a write error occurred on stdout. (Bug#9574)
9347 2011-09-21 Eli Zaretskii <eliz@gnu.org>
9349 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
9352 * dispextern.h (struct it): Update the comment documenting what
9355 2011-09-20 Eli Zaretskii <eliz@gnu.org>
9357 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9358 a display string, extend search for cursor position to end of row.
9359 (find_row_edges): If the row ends in a newline from a display
9360 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9361 Handle the case of a display string with multiple newlines.
9362 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9363 non-empty line. Fixes confusing cursor motion with arrow keys at
9364 the beginning of a line that starts with whitespace.
9366 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9368 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
9371 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
9373 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
9376 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9378 * xdisp.c (display_line): Record maximum and minimum buffer
9379 positions even if no glyphs were produced (e.g., by a zero-width
9380 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9381 buffer positions that will be removed from the glyph row because
9383 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9384 column is beyond frame width: don't subtract 1 "pixel" when
9385 computing width of the stretch.
9386 (reseat_at_next_visible_line_start): Undo the change made on
9387 2011-09-17 that saved paragraph information and restored it after
9388 the call to `reseat'. (Bug#9545)
9390 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9392 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
9393 and turn window cursor on if cleared (Bug#9415).
9395 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
9397 * search.c (boyer_moore): Take unibyte characters from pattern
9398 literally. (Bug#9458)
9400 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9402 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
9404 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
9406 Fix minor problem found by static checking.
9407 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
9408 initialized, to pacify gcc -Wuninitialized.
9410 * fileio.c: Report proper errno when syscall falls.
9411 (Finsert_file_contents): Save and restore errno,
9412 so that report_file_error outputs the correct diagnostic.
9413 (Fwrite_region) [CLASH_DETECTION]: Likewise.
9415 2011-09-18 Eli Zaretskii <eliz@gnu.org>
9417 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
9419 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9421 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
9422 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
9424 2011-09-17 Eli Zaretskii <eliz@gnu.org>
9426 * xdisp.c (reseat_at_next_visible_line_start): Keep information
9427 about the current paragraph and restore it after the call to reseat.
9429 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9430 (bidi_find_paragraph_start): Search back for paragraph beginning
9431 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9432 (bidi_move_to_visually_next): Only trigger paragraph-related
9433 computations when the last character is a newline or at EOB, not
9434 just any NEUTRAL_B. (Bug#9470)
9436 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9437 truncated lines if point is covered by a display string. (Bug#9524)
9439 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
9441 * xselect.c: Relax test for outgoing X longs (Bug#9498).
9442 (cons_to_x_long): New function.
9443 (lisp_data_to_selection_data): Use it. Correct the test for
9444 short-versus-long data; it was negated. Break out of vector
9445 loop, for efficiency, when a long datum is discovered.
9447 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
9449 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
9451 2011-09-16 Eli Zaretskii <eliz@gnu.org>
9453 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

9458 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
9459 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
9461 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
9463 * editfns.c (Fformat): Correctly handle text properties on "%%".

9470 * composite.c (composition_update_it, get_composition_id):
9471 * xdisp.c (get_next_display_element)
9472 (fill_composite_glyph_string): Add comments about special meaning
9473 of TAB characters in a composition.
9475 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
9477 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
9478 This occurs when processing a multibyte format.
9479 Problem reported by Wolfgang Jenker.
9481 2011-09-15 Johan Bockgård <bojohan@gnu.org>
9483 * xdisp.c (try_cursor_movement): Only check for exact match if
9484 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
9486 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9488 Remove unused external symbols.
9489 * dispextern.h (calc_pixel_width_or_height): Remove decl.
9490 * xdisp.c (calc_pixel_width_or_height): Now static.
9491 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
9492 * indent.c (check_display_width):
9493 * w32term.c: Fix comment to match code.
9494 * xterm.c, xterm.h (x_catching_errors): Remove.
9496 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
9498 * xselect.c: Use signed conversions more consistently (Bug#9498).
9499 (selection_data_to_lisp_data): Assume incoming selection data are
9500 signed integers, not unsigned. This is to be consistent with
9501 outgoing selection data, which was modified to use signed integers
9502 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9503 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9504 expects long, not unsigned long.
9506 2011-09-14 Eli Zaretskii <eliz@gnu.org>
9508 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
9509 computation of loop end. Reported by Johan Bockgård
9512 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
9514 * frame.c (Fother_visible_frames_p): Function deleted.
9516 2011-09-12 Eli Zaretskii <eliz@gnu.org>
9518 * indent.c (compute_motion): Process display vector front to back
9519 rather than the other way around. (Bug#2496)
9521 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
9523 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
9525 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
9527 * minibuf.c (Fread_from_minibuffer): Doc fix.
9529 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9531 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
9532 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
9534 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
9536 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
9537 value for non-existent files.
9539 2011-09-11 Eli Zaretskii <eliz@gnu.org>
9541 * fileio.c (Finsert_file_contents): If the file cannot be opened,
9542 set its "size" to -1. This will set the modtime_size field of
9543 the corresponding buffer to -1, which is what
9544 verify-visited-file-modtime expects for files that do not exist.
9547 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
9549 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
9551 * lisp.h: ... from here. push_key_description is no longer
9552 defined in keyboard.c, so its declaration should not be in
9553 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
9554 logically belongs with push_key_description.
9556 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
9558 * buffer.h: Include <sys/types.h> instead of <time.h>.
9559 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
9560 Problem reported by Herbert J. Skuhra.
9562 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
9564 * xml.c (parse_region): Make the parsing work for
9565 non-comment-starting XML files again (bug#9144).
9567 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
9569 * image.c (gif_load): Fix calculation of bottom and right corner.
9572 2011-09-10 Eli Zaretskii <eliz@gnu.org>
9574 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
9575 redisplay in small windows.
9577 2011-09-09 Eli Zaretskii <eliz@gnu.org>
9579 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
9581 2011-09-08 Martin Rudalics <rudalics@gmx.at>
9583 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):

9593 only under bidi iteration.
9595 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
9597 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
9599 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9601 isnan: Fix porting problem to Solaris 10 with bundled gcc.
9602 Without this fix, the command to link temacs failed due to an
9603 undefined symbol __builtin_isnan. This is because
9604 /usr/include/iso/math_c99.h #defines isnan(x) to
9605 __builtin_isnan(x), but the bundled gcc, which identifies itself
9606 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
9608 * floatfns.c (isnan): #undef, and then #define to a clone of
9610 (Fisnan): Always define, since it's always available now.
9611 (syms_of_floatfns): Always define isnan at the Lisp level.
9613 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9615 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
9617 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
9619 * fileio.c: Fix bugs with large file offsets (Bug#9428).
9620 The previous code assumed that file offsets (off_t values) fit in
9621 EMACS_INT variables, which is not true on typical 32-bit hosts.
9622 The code messed up by falsely reporting buffer overflow in cases
9623 such as (insert-file-contents "big" nil 1 2) into an empty buffer
9624 when "big" contains more than 2**29 bytes, even though this
9625 inserts just one byte and does not overflow the buffer.
9626 (Finsert_file_contents): Store file offsets as off_t
9627 values, not as EMACS_INT values. Check for overflow when
9628 converting between EMACS_INT and off_t. When checking for
9629 buffer overflow or for overlap, take the offsets into account.
9630 Don't use EMACS_INT for small values where int suffices.
9631 When checking for overlap, fix a typo: ZV was used where
9632 ZV_BYTE was intended.
9633 (Fwrite_region): Don't assume off_t fits into 'long'.
9634 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
9636 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
9638 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
9640 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9642 sprintf-related integer and memory overflow issues (Bug#9412).
9644 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
9645 (esprintf, exprintf, evxprintf): New functions.
9646 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
9647 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
9648 (modify_event_symbol): Do not assume that the length of
9649 name_alist_or_stem is safe to alloca and fits in int.
9650 (Fexecute_extended_command): Likewise for function name and binding.
9651 (Frecursion_depth): Wrap around reliably on integer overflow.
9652 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
9653 since some callers pass EMACS_INT values.
9654 (Fsingle_key_description): Don't crash if symbol name contains more
9655 than MAX_ALLOCA bytes.
9656 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
9657 (get_minibuffer): Arg is now EMACS_INT, not int.
9658 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
9659 (esprintf, exprintf, evxprintf): New decls.
9660 * window.h (command_loop_level, minibuf_level): Reflect API changes.
9662 * dbusbind.c (signature_cat): New function.
9663 (xd_signature, Fdbus_register_signal):
9664 Do not overrun buffer; instead, report string overflow.
9666 * dispnew.c (add_window_display_history): Don't overrun buffer.
9667 Truncate instead; this is OK since it's just a log.
9669 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
9670 even if the time zone offset is outlandishly large.
9671 Don't mishandle offset == INT_MIN.
9673 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
9674 when creating daemon; the previous buffer-overflow check was incorrect.
9676 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
9677 which has the guts of the old verror function.
9679 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
9680 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
9682 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
9683 (font_unparse_xlfd): Don't blindly alloca long strings.
9684 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
9685 fits in int, when using sprintf. Use single snprintf to count
9686 length of string rather than counting it via multiple sprintfs;
9687 that's simpler and more reliable.
9688 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
9689 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
9690 sprintf, in case result does not fit in int.
9692 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
9693 (fontset_from_font): Print it.
9695 * frame.c (tty_frame_count): Now printmax_t, not int.
9696 (make_terminal_frame, set_term_frame_name): Print it.
9697 (x_report_frame_params): In X, window IDs are unsigned long,
9698 not signed long, so print them as unsigned.
9699 (validate_x_resource_name): Check for implausibly long names,
9700 and don't assume name length fits in 'int'.
9701 (x_get_resource_string): Don't blindly alloca invocation name;
9702 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
9705 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
9706 (xg_check_special_colors, xg_set_geometry):
9707 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
9709 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
9710 Use esprintf, not sprintf, in case result does not fit in int.
9712 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9713 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
9714 it as a large positive number.
9715 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
9716 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
9718 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
9719 in case result does not fit in int.
9721 * print.c (float_to_string): Detect width overflow more reliably.
9722 (print_object): Make sprintf buffer a bit bigger, to avoid potential
9723 buffer overrun. Don't assume list length fits in 'int'. Treat
9724 print length of 0 as 0, not as infinity; to be consistent with other
9725 uses of print length in this function. Don't overflow print length
9726 index. Don't assume hash table size fits in 'long', or that
9727 vectorlike size fits in 'unsigned long'.
9729 * process.c (make_process): Use printmax_t, not int, to format
9730 process-name gensyms.
9732 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
9734 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
9735 to avoid potential buffer overrun.
9737 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
9738 if X resource line is longer than 512 bytes.
9740 * xfns.c (x_window): Make sprintf buffer a bit bigger
9741 to avoid potential buffer overrun.
9743 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
9745 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
9747 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
9749 Integer overflow fixes for scrolling, etc.
9750 Without these, Emacs silently mishandles large integers sometimes.
9751 For example, "C-u 4294967297 M-x recenter" was treated as if
9752 it were "C-u 1 M-x recenter" on a typical 64-bit host.
9754 * xdisp.c (try_window_id): Check Emacs fixnum range before
9755 converting to 'int'.
9757 * window.c (window_scroll_line_based, Frecenter):
9758 Check that an Emacs fixnum is in range before assigning it to 'int'.
9759 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
9760 values converted from Emacs fixnums.
9761 (Frecenter): Don't wrap around a line count if it is out of 'int'
9762 range; instead, treat it as an extreme value.
9763 (Fset_window_configuration, compare_window_configurations):
9764 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
9766 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
9767 that can exceed INT_MAX. Check that EMACS_INT value is in range
9768 before assigning it to the (possibly-narrower) index.
9769 (match_limit): Don't assume that a fixnum can fit in 'int'.
9771 * print.c (print_object): Use ptrdiff_t, not int, for index that can
9774 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
9775 (Fvertical_motion): Don't wrap around LINES values that don't fit
9776 in 'int'. Instead, treat them as extreme values. This is good
9777 enough for windows, which can't have more than INT_MAX lines anyway.
9779 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9781 * Require libxml/parser.h to avoid compilation warning.
9783 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
9785 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
9786 since this reportedly can destroy thread storage.
9788 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
9790 * syntax.c (find_defun_start): Update all cache variables if
9791 exiting early (Bug#9401).
9793 2011-08-30 Eli Zaretskii <eliz@gnu.org>
9795 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
9797 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
9798 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
9799 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
9801 * term.c (tty_append_glyph): New function.
9802 (produce_stretch_glyph): Static function and its prototype deleted.
9804 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
9807 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
9809 * image.c (parse_image_spec): Check for nonnegative, not for positive,
9810 when checking :margin (Bug#9390).
9811 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
9812 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
9813 so that the name doesn't mislead. All uses changed.
9815 2011-08-28 Johan Bockgård <bojohan@gnu.org>
9817 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
9820 2011-08-27 Eli Zaretskii <eliz@gnu.org>
9822 * xdisp.c (move_it_to): Don't bail out early when reaching
9823 position beyond to_charpos, if we are scanning backwards.
9824 (move_it_vertically_backward): When DY == 0, make sure we get to
9825 the first character in the line after the newline.
9827 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
9829 * ccl.c: Improve and simplify overflow checking (Bug#9196).
9830 (ccl_driver): Do not generate an out-of-range pointer.
9831 (Fccl_execute_on_string): Remove unnecessary check for
9832 integer overflow, noted by Stefan Monnier in
9833 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
9834 Remove a FIXME that didn't need fixing.
9835 Simplify the newly-introduced buffer reallocation code.
9837 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
9839 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
9841 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
9843 Integer and memory overflow issues (Bug#9196).
9845 * doc.c (get_doc_string): Rework so that
9846 get_doc_string_buffer_size is the actual buffer size, rather than
9847 being 1 less than the actual buffer size; this makes xpalloc more
9850 * image.c (x_allocate_bitmap_record, cache_image):
9851 * xselect.c (Fx_register_dnd_atom):
9852 Simplify previous changes by using xpalloc.
9854 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
9855 since either will do and ptrdiff_t is convenient with xpalloc.
9857 * charset.c (charset_table_size)
9858 (struct charset_sort_data.priority): Now ptrdiff_t.
9859 (charset_compare): Don't overflow if priorities differ greatly.
9860 (Fsort_charsets): Don't assume list length fits in int.
9861 Check for size-calculation overflow when allocating sort data.
9862 (syms_of_charset): Allocate an initial charset table that is
9863 just under 64 KiB, to avoid problems with glibc malloc and mmap.
9865 * cmds.c (internal_self_insert): Check for size-calculation overflow.
9867 * composite.h (struct composition.glyph_len): Now int, not unsigned.
9868 The actual value is always <= INT_MAX, and leaving it unsigned made
9869 overflow checking harder.
9871 * dispextern.h (struct glyph_matrix.rows_allocated)
9872 (struct face_cache.size): Now ptrdiff_t, for convenience in use
9873 with xpalloc. The values are still always <= INT_MAX.
9875 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
9877 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
9878 (SAFE_NALLOCA): New macro.
9880 * region-cache.c (struct boundary.pos, find_cache_boundary)
9881 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
9882 (set_cache_region, invalidate_region_cache)
9883 (revalidate_region_cache, know_region_cache, region_cache_forward)
9884 (region_cache_backward, pp_cache):
9885 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
9886 so that ptrdiff_t * can be passed to xpalloc.
9887 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
9888 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
9889 (pp_cache): Don't assume cache_len fits in int.
9890 * region-cache.h: Adjust extern decls to match.
9892 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
9893 EMACS_INT, since either will do, for xpalloc.
9895 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
9896 (xnmalloc, xnrealloc, xpalloc): New functions.
9898 * bidi.c (bidi_shelve_header_size): New constant.
9899 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
9900 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
9902 * bidi.c (bidi_cache_shrink):
9903 * buffer.c (overlays_at, overlays_in, record_overlay_string)
9905 Don't update size of array until after memory allocation succeeds,
9906 because xmalloc/xrealloc may not return.
9907 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
9908 now that we have proper integer overflow checking.
9909 (record_overlay_string, overlay_strings): Catch overflows when
9910 calculating size of overlay_str_buf.
9912 * callproc.c (Fcall_process): Check for size overflow when
9913 calculating size of args2.
9914 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
9915 Normally we prefer signed values, but sticking with ptrdiff_t would
9916 require adding more-complicated checks.
9918 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
9919 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
9920 Redo buffer-overflow calculations to avoid integer overflow.
9921 Add a FIXME comment where memory seems to be over-allocated.
9923 * character.c (Fstring): Check for size-calculation overflow.
9925 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
9926 unnecessary integer overflow. Check for size overflow.
9927 (encode_coding_object): Don't update size until xmalloc succeeds.
9929 * composite.c (get_composition_id): Check for overflow in glyph
9930 length calculations.
9932 Integer and memory overflow fixes for display code.

9959 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
9961 * emacs.c (main): Do not reallocate argv, since there is a null at
9962 the end that can be overwritten, and this way there's no need to
9963 worry about size-calculation overflow.

10093 (X_LONG_MIN): New macros.
10094 Use them to make the following changes clearer.
10095 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

10098 (SELECTION_QUANTUM): Remove, replacing with ...
10099 (selection_quantum): ... new function, which avoids overflow.
10101 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10102 assumption that selection length fits in 'int'.

10119 Don't store size until memory allocation succeeds.
10120 (x_get_window_property): Plug memory leak on memory exhaustion.
10121 Don't double-block input; malloc is safe here. Don't assume 2**34
10122 - 4 fits in unsigned long. Add an xassert to check
10123 XGetWindowProperty overflow. Be more careful about overflow
10124 calculations, and distinguish size from memory overflow better.
10125 (receive_incremental_selection): When tracing, don't assume
10126 unsigned int is less than INT_MAX.
10127 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

10131 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10132 result parameters unless successful. Rely on cons_to_unsigned
10133 to report problems with elements; the old code wasn't right anyway.
10134 (x_check_property_data): Check for int overflow; we cannot use
10135 a wider type due to X limits.

10168 * lisp.h (hash_lookup, hash_put):
10169 * minibuf.c (Ftest_completion):
10170 Use ptrdiff_t for hash table indexes, not int (which is too
10171 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

10204 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10205 (x_send_scroll_bar_event): Likewise. Check that the size does not
10206 exceed limits imposed by XClientMessageEvent, as well as the usual
10207 ptrdiff_t and size_t limits.
10209 * keyboard.c: Overflow, signedness and related fixes.
10210 (make_lispy_movement): Use same integer type in forward decl
10211 that is used in the definition.

10213 Change bufsize argument back to int, undoing my 2011-03-30 change.
10214 We prefer signed types, and int is wide enough here.
10215 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10216 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10217 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10218 length, not size_t. Use ptrdiff_t for index, not int.
10219 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10220 possibility of integer overflow.

10248 Prefer int to unsigned where either will do.
10249 (tiff_handler): New function, combining the cores of the
10250 old tiff_error_handler and tiff_warning_handler.

10252 stack buffer overflows. It uses only the features of vsnprintf
10253 that are common to both POSIX and native Microsoft.
10254 (tiff_error_handler, tiff_warning_handler): Use it.
10255 (tiff_load, gif_load, imagemagick_load_image):
10256 Don't assume :index value fits in 'int'.

10259 the integer types that MagickCropImage accepts. Don't assume
10260 Vimagemagick_render_type has a nonnegative value. Don't assume

10276 (handle_single_display_spec): If the display spec is of the form
10277 `(space ...)', and specifies display in the text area, return 2
10279 (try_cursor_movement): Check for the need to scroll more
10280 accurately, and prefer exact match for point under bidi.
10281 Don't advance `row' beyond the last row of the window.

10302 positioning on the newline at EOL of R2L text within L2R
10303 paragraph, and vice versa.
10304 (try_cursor_movement): Check continued rows, in addition to
10305 continuation rows. Fixes unwarranted scroll when point enters a
10306 continued line of R2L text within an L2R paragraph, or vice versa.
10307 (cursor_row_p): Consider the case of point being equal to
10308 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10309 from the end of a short line to the beginning of a continued line
10310 of R2L text within L2R paragraph.

10337 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10338 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10339 candidate is selected by the mouse, and that candidate has a
10340 composed character under the mouse.
10342 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10343 coordinates reported by pos-visible-in-window-p for a composed

10353 consider it a hit if to_charpos is anywhere in the range of the
10354 composed buffer positions.
10356 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10358 * image.c (gif_load): Don't assume that each subimage has the same
10359 dimensions as the base image. Handle disposal method that is
10360 "undefined" by the gif spec (Bug#9335).

10367 2011-08-19 Eli Zaretskii <eliz@gnu.org>
10369 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
10370 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10371 from an Org mode buffer to a Speedbar frame.
10373 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10374 a composition, take its buffer position from IT->cmp_it.charpos.
10375 Fixes cursor positioning at the beginning of a line that begins
10376 with a composed character.
10378 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10380 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10381 character bidirectional type, use STRONG_L instead. Fixes crashes
10382 in a buffer produced by `describe-categories'.
10384 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10385 members before the level stack, so they would be saved and
10386 restored when copying iterator state. Fixes incorrect reordering
10387 around TABs covered by display properties.
10389 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10391 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

10396 (internal_condition_case_2, internal_condition_case_n):
10397 Remove unnecessary aborts (Bug#9081).
10399 2011-08-17 Eli Zaretskii <eliz@gnu.org>
10401 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
10402 has no `load' handler, try opening the file locally. (Bug#9311)
10404 2011-08-16 Ken Brown <kbrown@cornell.edu>
10406 * gmalloc.c: Expand comment.
10408 2011-08-16 Eli Zaretskii <eliz@gnu.org>

10424 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
10425 in the static heap.
10426 [CYGWIN] (special_realloc): New function.
10427 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

10443 * chartab.c: Improve commentary for the uniprop_table API.
10445 * bidi.c (bidi_paragraph_init): Support zero value of
10446 bidi_ignore_explicit_marks_for_paragraph_level.
10447 (bidi_initialize): Use uniprop_table instead of including
10448 biditype.h and bidimirror.h.
10450 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
10451 coordinates of the iterator when restoring from ppos_it.
10454 2011-08-14 Kenichi Handa <handa@m17n.org>

10461 * xdisp.c (move_it_in_display_line_to): Don't invoke
10462 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
10463 ppos_it. Fixes vertical cursor motion when line beginning is
10464 covered by an image. (Bug#9296)
10466 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
10468 * nsterm.h (ns_run_ascript): Declare.
10469 (NSAPP_DATA2_RUNASSCRIPT): Define.
10471 * nsfns.m (as_script, as_result, as_status): New static variables.
10472 (ns_run_ascript): New function.
10473 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10474 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10475 the event loop. Get status from as_status (Bug#7276).
10477 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10478 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10479 the event loop (Bug#7276).
10481 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10483 * gnutls.c (QCgnutls_bootprop_priority)
10484 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
10485 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10486 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10487 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10488 (QCgnutls_bootprop_verify_hostname_error)
10489 (QCgnutls_bootprop_callbacks_verify): Rename from
10490 Qgnutls_bootprop_..., all uses changed.

10504 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10505 (Fnetwork_interface_list): Allocate in increments of bytes instead
10506 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10507 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10509 (struct ifflag_def): notrailers is smart on OSX.
10510 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10511 Get hardware address with getifaddrs if available.
10513 2011-08-12 Eli Zaretskii <eliz@gnu.org>
10515 * xdisp.c (iterate_out_of_display_property): xassert that
10516 IT->position is set to within IT->object's boundaries. Break from
10517 the loop as soon as EOB is reached; avoids infloops in redisplay
10518 when IT->position is set up wrongly due to some bug.
10519 Set IT->current to match the bidi iterator unconditionally.
10520 (push_display_prop): Allow GET_FROM_STRING as IT->method on
10521 entry. Force push_it to save on the stack the current
10522 buffer/string position, to be restored by pop_it. Fix flags in
10523 the iterator structure wrt the object coming from a display
10524 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
10525 properties. (Bug#9284)
10527 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
10529 * fontset.c (fontset_get_font_group): Add proper type checks.
10532 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

10542 no-display-properties-and-no-overlays under bidi display.
10543 Set disp_pos in the bidi iterator to avoid searches for display
10544 properties and overlays.
10546 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
10548 * editfns.c (Fset_time_zone_rule): Document relationship with the

10552 the font entity extracted from the cache (Bug#8109).
10554 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
10556 * composite.c (autocmp_chars): Don't reset point. That is done by
10557 restore_point_unwind (Bug#5984).
10559 2011-08-07 Juri Linkov <juri@jurta.org>
10561 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
10562 to show the arg `TIME' instead of `TIMEVAL'.
10564 2011-08-06 Eli Zaretskii <eliz@gnu.org>
10566 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
10567 display property strides EOL and includes a newline, as in
10568 longlines-mode. (Bug#9254)
10569 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
10570 word-wrap under bidirectional display. (Bug#9224)
10572 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
10573 is non-zero, even if the data buffer is NULL. Fixes a crash in
10574 vertical-motion with longlines-mode. (Bug#9254)
10576 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10578 * bidi.c <bidi_cache_total_alloc>: Now static.
10579 (bidi_initialize): Initialize bidi_cache_total_alloc.
10581 * xdisp.c (display_line): Release buffer allocated for shelved bidi
10584 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
10585 amount allocated this far in `bidi_cache_total_alloc'.
10586 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
10587 non-zero, only free the data buffer without restoring the cache
10588 contents. All callers changed.
10590 * dispextern.h (bidi_unshelve_cache): Update prototype.
10592 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
10593 (move_it_in_display_line, move_it_to)
10594 (move_it_vertically_backward, move_it_by_lines): Replace the call
10595 to xfree to an equivalent call to bidi_unshelve_cache.
10596 (move_it_in_display_line_to): Fix logic of returning
10597 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
10599 2011-08-05 Eli Zaretskii <eliz@gnu.org>
10601 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
10602 came from a string character with a `cursor' property. (Bug#9229)
10604 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10606 * Makefile.in (LIB_PTHREAD): New variable.
10607 (LIBES): Add LIB_PTHREAD (Bug#9216).
10609 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
10610 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
10612 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
10614 * regex.c (re_iswctype): Remove some redundant boolean conversions.
10616 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
10618 * xterm.c (x_find_topmost_parent): New function.
10619 (x_set_frame_alpha): Find topmost parent window with
10620 x_find_topmost_parent and set the property there also (bug#9181).
10621 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
10623 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
10625 * callproc.c (Fcall_process): Avoid vfork clobbering
10626 the local vars buffer, coding_systems, current_dir.
10628 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>

10632 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
10634 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
10635 so that it is not optimized away.
10637 * xdisp.c (compute_display_string_pos): Remove unused local.
10639 2011-08-02 Eli Zaretskii <eliz@gnu.org>
10641 Fix slow cursor motion and scrolling in large buffers with
10642 selective display, like Org Mode buffers. (Bug#9218)
10644 * dispextern.h (struct bidi_it): New member disp_prop_p.
10646 * xdisp.c: Remove one-slot cache of display string positions.
10647 (compute_display_string_pos): Accept an additional argument
10648 DISP_PROP_P; callers changed. Scan at most 5K characters forward
10649 for a display string or property. If found, set DISP_PROP_P
10652 * bidi.c (bidi_fetch_char): Accept an additional argument
10653 DISP_PROP_P, and pass it to compute_display_string_pos.
10654 Only handle text covered by a display string if DISP_PROP_P is returned
10655 non-zero. All callers of bidi_fetch_char changed.
10657 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
10659 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
10661 2010-12-03 Don March <don@ohspite.net>
10663 * keymap.c (Fdefine_key): Fix non-prefix key error message when
10664 last character M-[char] is translated to ESC [char] (bug#7541).
10666 2011-08-02 Kenichi Handa <handa@m17n.org>
10668 * lisp.h (uniprop_table): Extern it.
10670 * chartab.c (uniprop_table): Make it non-static.
10672 2011-08-01 Eli Zaretskii <eliz@gnu.org>
10674 * xdisp.c (forward_to_next_line_start): Accept additional argument
10675 BIDI_IT_PREV, and store into it the state of the bidi iterator had
10677 (reseat_at_next_visible_line_start): Use the bidi iterator state
10678 returned by forward_to_next_line_start to restore the state of
10679 it->bidi_it after backing up to previous newline. (Bug#9212)
10681 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
10683 * regex.c (re_comp): Protoize.
10684 (re_exec): Fix return type.
10685 (regexec): Fix type of `ret'. (Bug#9203)
10687 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10689 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
10690 This is needed if max-image-size is a floating-point number.
10692 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10694 * print.c (print_object): Print empty symbol as ##.
10696 * lread.c (read1): Read ## as empty symbol.
10698 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10700 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
10701 setting frame foreground color (Bug#9175).
10702 (x_set_background_color): Likewise.
10704 * nsmenu.m (-setText): Size tooltip dimensions precisely to
10705 contents (Bug#9176).
10706 (EmacsTooltip -init): Remove bezels and add shadows to
10709 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
10710 or scroll bar (Bug#8470).
10712 * nsfont.m (nsfont_open): Remove assignment to voffset and
10713 unnecessary vars hshink, expand, hd, full_height, min_height.
10714 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
10716 * nsterm.h (nsfont_info): Remove voffset field.
10718 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
10720 Implement strike-through and overline on NextStep (Bug#8863).
10722 * nsfont.m (nsfont_open): Use underline position provided by font,
10723 instead of hard-coded value of 2.
10724 (nsfont_draw): Call ns_draw_text_decoration instead.
10726 * nsterm.h: Add declaration for ns_draw_text_decoration.
10728 * nsterm.m (ns_draw_text_decoration): New function for drawing
10729 underline, overline, and strike-through.

10731 ns_draw_text_decoration. Change treatment of cursor drawing to
10732 accommodate underlining, etc.
10734 2011-07-28 Eli Zaretskii <eliz@gnu.org>
10736 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
10739 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10741 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
10742 Without this fix, if a signal arrives just after memory fills up,
10743 'malloc' might be invoked reentrantly.
10745 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
10746 In other words, assume that every image size is allowed, on non-X
10747 hosts. This assumption is probably wrong, but it lets Emacs compile.
10749 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
10751 * regex.c (re_iswctype): Convert return values to boolean.
10753 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
10755 * xdisp.c (compute_display_string_pos): Don't use cached display
10756 string position if the buffer had its restriction changed.
10759 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10761 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10763 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
10765 Integer signedness and overflow and related fixes. (Bug#9079)
10767 * bidi.c: Integer size and overflow fixes.
10768 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
10769 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
10770 (bidi_cache_find_level_change, bidi_cache_ensure_space)
10771 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
10772 (bidi_find_other_level_edge):
10773 Use ptrdiff_t instead of EMACS_INT where either will do.
10774 This works better on 32-bit hosts configured --with-wide-int.
10775 (bidi_cache_ensure_space): Check for size-calculation overflow.
10776 Use % rather than repeated addition, for better worst-case speed.
10777 Don't set bidi_cache_size until after xrealloc returns, because it
10779 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
10780 (bidi_cache_ensure_space): Also check that the bidi cache size
10781 does not exceed that of the largest Lisp string or buffer. See Eli
10782 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
10784 * alloc.c (__malloc_size_t): Remove.
10785 All uses replaced by size_t. See Andreas Schwab's note
10786 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
10788 * image.c: Improve checking for integer overflow.
10789 (check_image_size): Assume that f is nonnull, since
10790 it is always nonnull in practice. This is one less thing to
10791 worry about when checking for integer overflow later.
10792 (x_check_image_size): New function, which checks for integer
10793 overflow issues inside X.
10794 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
10795 This removes the need for a memory_full check.
10796 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
10797 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
10798 (xbm_read_bitmap_data): Change locals back to 'int', since
10799 their values must fit in 'int'.
10800 (xpm_load_image, png_load, tiff_load):
10801 Invoke x_create_x_image_and_pixmap earlier,
10802 to avoid much needless work if the image is too large.
10803 (tiff_load): Treat overly large images as if
10804 x_create_x_image_and_pixmap failed, not as malloc failures.
10805 (gs_load): Use x_check_image_size.
10807 * gtkutil.c: Omit integer casts.
10808 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
10809 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
10811 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
10813 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
10814 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
10815 would wrongly return t on a 64-bit host.
10817 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
10818 The plain *_OVERFLOW macros run afoul of GCC bug 49705
10819 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
10820 and therefore cause GCC to emit a bogus diagnostic in some cases.
10822 * image.c: Integer signedness and overflow and related fixes.
10823 This is not an exhaustive set of fixes, but it's time to
10824 record what I've got.
10825 (lookup_pixel_color, check_image_size): Remove redundant decls.
10826 (check_image_size): Don't assume that arbitrary EMACS_INT values
10827 fit in 'int', or that arbitrary 'double' values fit in 'int'.
10828 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
10829 (tiff_load, imagemagick_load_image):
10830 Check for overflow in size calculations.
10831 (x_create_x_image_and_pixmap): Remove unnecessary test for
10832 xmalloc returning NULL; that can't happen.
10833 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
10834 (xpm_color_bucket): Use better integer hashing function.
10835 (xpm_cache_color): Don't possibly over-allocate memory.
10836 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
10837 (gif_memory_source):
10838 Use ptrdiff_t, not int or size_t, to record sizes.
10839 (png_load): Don't assume values greater than 2**31 fit in 'int'.
10840 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
10841 either works, as we prefer signed integers.
10842 (tiff_read_from_memory, tiff_write_from_memory):
10843 Return tsize_t, not size_t, since that's what the TIFF API wants.
10844 (tiff_read_from_memory): Don't fail simply because the read would
10845 go past EOF; instead, return a short read.
10846 (tiff_load): Omit no-longer-needed casts.
10847 (Fimagemagick_types): Don't assume size fits into 'int'.
10849 Improve hashing quality when configured --with-wide-int.
10850 * fns.c (hash_string): New function, taken from sxhash_string.
10851 Do not discard information about ASCII character case; this
10852 discarding is no longer needed.
10853 (sxhash-string): Use it. Change sig to match it. Caller changed.
10854 * lisp.h: Declare it.
10855 * lread.c (hash_string): Remove, since we now use fns.c's version.
10856 The fns.c version returns a wider integer if --with-wide-int is
10857 specified, so this should help the quality of the hashing a bit.
10859 * emacs.c: Integer overflow minor fix.
10860 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
10861 Define only if GNU_LINUX.
10862 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
10864 * dispnew.c: Integer signedness and overflow fixes.
10865 Remove unnecessary forward decls, that were a maintenance hassle.
10866 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
10868 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
10869 (scrolling_window): Use ptrdiff_t, not int, for byte count.
10870 (prepare_desired_row, line_draw_cost):
10871 Use int, not unsigned, where either works.
10872 (save_current_matrix, restore_current_matrix):
10873 Use ptrdiff_t, not size_t, where either works.
10874 (init_display): Check for overflow more accurately, and without
10875 relying on undefined behavior.
10877 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
10878 Remove, replacing with the new symbols in lisp.h. All uses changed.
10879 * fileio.c (make_temp_name):
10880 * filelock.c (lock_file_1, lock_file):
10881 * xdisp.c (message_dolog):
10882 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
10883 Use pMd etc. instead.
10884 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
10885 replacing the pWIDE etc. symbols removed from editfns.c.
10887 * keyboard.h (num_input_events): Now uintmax_t.
10888 This is (very slightly) less likely to mess up due to wraparound.
10891 * buffer.c: Integer signedness fixes.
10892 (alloc_buffer_text, enlarge_buffer_text):
10893 Use ptrdiff_t rather than size_t when either will do, as we prefer
10896 * alloc.c: Integer signedness and overflow fixes.
10897 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
10898 (__malloc_size_t): Default to size_t, not to int.
10899 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
10900 (Fgarbage_collect, mark_object_loop_halt, mark_object):
10901 Prefer ptrdiff_t to size_t when either would do, as we prefer
10903 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
10904 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
10905 Now const. Initialize with values that are in range even if char
10907 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
10908 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
10909 These functions do the right thing with sizes > 2**32.
10910 (check_depth): Now ptrdiff_t, not int.
10911 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
10912 Adjust to new way of storing sizes. Check for size overflow bugs
10914 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
10915 slightly wrong anyway, as it missed one instance of
10916 XMALLOC_OVERRUN_CHECK_OVERHEAD.
10917 (refill_memory_reserve): Omit needless cast to size_t.
10918 (mark_object_loop_halt): Mark as externally visible.
10920 * xselect.c: Integer signedness and overflow fixes.
10921 (Fx_register_dnd_atom, x_handle_dnd_message):
10922 Use ptrdiff_t, not size_t, since we prefer signed.
10923 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
10924 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
10925 x_dnd_atoms_size and x_dnd_atoms_length.
10927 * doprnt.c: Prefer signed to unsigned when either works.
10929 * doprnt.c (doprnt):
10931 * xdisp.c (vmessage):
10932 Use ptrdiff_t, not size_t, when using or implementing doprnt,
10933 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
10934 prefer signed arithmetic to avoid comparison confusion.
10935 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
10936 but is a bit tricky.
10938 Assume freestanding C89 headers, string.h, stdlib.h.
10939 * data.c, doprnt.c, floatfns.c, print.c:
10940 Include float.h unconditionally.
10941 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
10942 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
10943 * regex.c: Likewise for stddef.h, string.h.
10944 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
10945 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
10946 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
10947 (STDC_HEADERS): Remove obsolete defines.
10948 * sysdep.c: Include limits.h unconditionally.
10950 Assume support for memcmp, memcpy, memmove, memset.
10951 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
10952 * regex.c (memcmp, memcpy):
10953 Remove; we assume C89 now.
10955 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
10956 (__malloc_safe_bcopy): Remove; no longer needed.
10958 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
10959 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
10960 well either way, and we prefer signed to unsigned.
10962 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
10964 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
10965 closes the connection while we're reading (bug#9182).
10967 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
10969 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
10970 are specified (Bug#9168).
10972 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
10974 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
10975 Found by GCC static checking and --with-wide-int on a 32-bit host.
10977 2011-07-25 Eli Zaretskii <eliz@gnu.org>
10979 * xdisp.c (compute_display_string_pos): Fix logic of caching
10980 previous display string position. Initialize cached_prev_pos to
10981 -1. Fixes slow-down at the beginning of a buffer.
10983 2011-07-24 Eli Zaretskii <eliz@gnu.org>
10985 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
10986 for attrs[LFACE_FONTSET_INDEX].
10988 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
10990 * xml.c (parse_region): Remove unused local
10991 that was recently introduced.
10993 2011-07-23 Eli Zaretskii <eliz@gnu.org>
10995 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
10996 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
10998 * xdisp.c (move_it_in_display_line_to): Record the best matching
10999 position for TO_CHARPOS while scanning the line, and restore it on
11000 exit if none of the characters scanned was an exact match.
11001 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11002 when exact match is impossible due to invisible text, and the
11003 lines are truncated.
11005 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11007 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11010 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11012 Fix a significant slow-down of cursor motion with C-n, C-p,
11013 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11014 auto-repeat under bidi redisplay in fontified buffers.
11015 * xdisp.c (compute_stop_pos_backwards): New function.
11016 (next_element_from_buffer): Call compute_stop_pos_backwards to
11017 find a suitable prev_stop when we find ourselves before
11019 (reseat): Don't look for prev_stop, as that could mean a very long
11021 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11022 <cached_disp_overlay_modiff>: Cache for last found display string
11024 (compute_display_string_pos): Return the cached position if asked
11025 about the same buffer in the same area of character positions, and
11026 the buffer wasn't changed since the time the display string
11027 position was cached.
11029 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11031 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11032 is an integer, which is important for empty lines. (Bug#9149)
11034 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11036 * frame.c (Fmodify_frame_parameters): In tty case, update the
11037 default face if necessary (Bug#4238).
11039 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11041 * editfns.c (Fstring_to_char): No need to explain what a character
11042 is in the docstring (Bug#6576).
11044 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11046 * xml.c (parse_region): Make sure we always return a tree.
11048 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11050 * xml.c (parse_region): If a document contains only comments,
11053 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11055 * xml.c (make_dom): Return comments, too.
11057 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11060 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11061 and the surrounding thread.
11062 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11063 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11064 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11066 * s/openbsd.h (BROKEN_SIGIO): Define.
11067 * unexelf.c (unexec) [__OpenBSD__]:
11068 Don't update the .mdebug section of the Alpha COFF symbol table.
11070 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11072 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11075 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11077 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11078 This fixes some race conditions on the permissions of any newly
11081 * alloc.c (valid_pointer_p): Use pipe, not open.
11082 This fixes some permissions issues when debugging.
11084 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11085 If fchown fails to set both uid and gid, try to set just gid,
11086 as that is sometimes allowed. Adjust the file's mode to eliminate
11087 setuid or setgid bits that are inappropriate if fchown fails.
11089 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11091 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11092 to compare Lisp_Objects.
11093 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11094 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11095 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11097 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11099 * lread.c (read_integer): Unread even EOF character.
11100 (read1): Likewise. Properly record start position of symbol.
11102 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11103 symbol character follows.
11105 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11107 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11108 This works around a problem with the previous change to Fcopy_file.
11109 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11110 and without this change, GCC might complain about discarding
11111 fchown's return value.
11113 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11115 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11117 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11119 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11121 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11123 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11124 it's used from the C level.
11126 * process.c: Use the same condition for POLL_FOR_INPUT in both
11127 keyboard.c and process.c (bug#1858).
11129 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11131 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11132 (Fgnutls_boot): Use it.
11134 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11136 * doc.c (Fsubstitute_command_keys): Revert last change.
11138 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11140 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11141 quotes the next character, and doesn't affect other longer
11142 sequences (bug#8935).
11144 * lread.c (syms_of_lread): Clarify that is isn't only
11145 `eval-buffer' and `eval-defun' that's affected by
11146 `lexical-binding' (bug#8460).
11148 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11150 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11151 bidi redisplay when a line includes both an image and is truncated.
11153 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11155 Fix minor problems found by static checking.
11156 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11157 (elsz): Now a signed constant, not a size_t var. We prefer signed
11158 types to unsigned, to avoid integer comparison confusion. Without
11159 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11160 "cannot optimize loop, the loop counter may overflow", a symptom
11162 * indent.c (Fvertical_motion): Mark locals as initialized.
11163 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11165 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11167 * search.c (Fre_search_backward): Mention `case-fold-search' in
11168 all the re_search_* functions (bug#8138).
11170 * keyboard.c (Fopen_dribble_file): Document when the file is
11173 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11175 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11178 Support bidi reordering of display and overlay strings.

11180 (compute_display_string_end): Accept additional argument STRING.
11181 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11182 (reseat_to_string): Initialize bidi_it->string.s and
11183 bidi_it->string.schars.
11184 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11185 NULL (avoids a crash in bidi_paragraph_init).
11186 Initialize itb.string.lstring.
11187 (init_iterator): Call bidi_init_it only of a valid
11188 buffer position was specified. Initialize paragraph_embedding to
11190 (reseat_to_string): Initialize the bidi iterator.
11191 (display_string): If we need to ignore text properties of
11192 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11193 original value of -1 will not work with bidi.)
11194 (compute_display_string_pos): First arg is now struct
11195 `text_pos *'; all callers changed. Support display properties on
11197 (compute_display_string_end): Support display properties on Lisp
11199 (init_iterator, reseat_1, reseat_to_string): Initialize the
11200 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11201 when iterating on a string not from display properties).
11202 (compute_display_string_pos, compute_display_string_end):
11203 Fix calculation of the object to scan. Fixes an error when using
11205 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11206 base_level_stop; instead, set base_level_stop to BEGV.
11207 Fixes crashes in vertical-motion.
11208 (next_element_from_buffer): Improve commentary for when
11209 the iterator is before prev_stop.
11210 (init_iterator): Initialize bidi_p from the default value of
11211 bidi-display-reordering, not from buffer-local value. Use the
11212 buffer-local value only if initializing for buffer iteration.
11213 (handle_invisible_prop): Support invisible properties on strings
11214 that are being bidi-reordered.
11215 (set_iterator_to_next): Support bidi reordering of C strings and
11217 (next_element_from_string): Support bidi reordering of Lisp
11219 (handle_stop_backwards): Support Lisp strings as well.
11220 (display_string): Support display of R2L glyph rows.
11221 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11222 (init_iterator): Don't initialize it->bidi_p for strings
11224 (reseat_to_string): Initialize it->bidi_p for strings here.
11225 (next_element_from_string, next_element_from_c_string)
11226 (next_element_from_buffer): Add xassert's for correspondence
11227 between IT's object being iterated and it->bidi_it.string
11229 (face_before_or_after_it_pos): Support bidi iteration.
11230 (next_element_from_c_string): Handle the case of the first string
11231 character that is not the first one in the visual order.
11232 (get_visually_first_element): New function, refactored from common
11233 parts of next_element_from_buffer, next_element_from_string, and
11234 next_element_from_c_string.
11235 (tool_bar_lines_needed, redisplay_tool_bar)
11236 (display_menu_bar): Force left-to-right direction. Add a FIXME
11237 comment for making that be controlled by a user option.
11238 (push_it, pop_it): Save and restore the state of the
11239 bidi iterator. Save and restore the bidi_p flag.
11240 (pop_it): Iterate out of display property for string iteration as
11242 (iterate_out_of_display_property): Support iteration over strings.
11243 (handle_single_display_spec): Set up it->bidi_it for iteration
11244 over a display string, and call bidi_init_it.
11245 (handle_single_display_spec, next_overlay_string)
11246 (get_overlay_strings_1, push_display_prop): Set up the bidi
11247 iterator for displaying display or overlay strings.
11248 (forward_to_next_line_start): Don't use the shortcut if
11250 (back_to_previous_visible_line_start): If handle_display_prop
11251 pushed the iterator stack, restore the internal state of the bidi
11252 iterator by calling bidi_pop_it same number of times.
11253 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
11254 and we are bidi-iterating, don't decrement the iterator position;
11255 instead, set the first_elt flag in the bidi iterator, to produce
11257 (reseat_1): Remove redundant setting of string_from_display_prop_p.
11258 (push_display_prop): xassert that we are iterating a buffer.
11259 (push_it, pop_it): Save and restore paragraph_embedding member.
11260 (handle_single_display_spec, next_overlay_string)
11261 (get_overlay_strings_1, reseat_1, reseat_to_string)
11262 (push_display_prop): Set up the `unibyte' member of bidi_it.string
11263 correctly. Don't assume unibyte strings are not bidi-reordered.
11264 (compute_display_string_pos)
11265 (compute_display_string_end): Fix handling the case of C string.

11726 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
11728 Random fixes. E.g., (random) never returned negative values.
11729 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
11730 subseconds part to the entropy, as that's a bit more random.
11731 Prefer signed to unsigned, since the signedness doesn't matter and
11732 in general we prefer signed. When given a limit, use a
11733 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
11734 latter isn't right if USE_2_TAGS_FOR_INTS.
11735 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
11736 not 0..VALMASK. Don't discard "excess" bits that random () returns.
11738 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11740 * textprop.c (text_property_stickiness):
11741 Obey Vtext_property_default_nonsticky.

11748 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
11749 This is more efficient than Ffile_directory_p and avoids a minor race.
11751 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
11753 * buffer.c (Foverlay_put): Say what the return value is
11756 * fileio.c (barf_or_query_if_file_exists): Check first if the file
11757 is a directory before asking whether to use the file name
11759 (barf_or_query_if_file_exists): Make the "File is a directory"
11760 error be more correct.
11762 * fns.c (Frequire): Remove the mention of the .gz files, since
11763 that's installation-specific, but keep the mention of
11764 `get-load-suffixes'.
11766 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
11768 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

11773 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
11774 (syms_of_gnutls): Remove duplicate DEFSYM for

11776 Qgnutls_bootprop_verify_error (which is no longer used).
11778 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
11779 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
11780 Also (re)move comments that are misplaced or no longer relevant.
11782 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
11784 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

11812 * fns.c (Frequire): Mention .el.gz files (bug#7314).
11813 (Frequire): Mention get-load-suffixes.
11815 2011-07-02 Martin Rudalics <rudalics@gmx.at>

11843 (syms_of_keymap): Defsubr make-composed-keymap.
11844 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

11881 * eval.c (struct backtrace): Simplify and port the data structure.
11882 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
11883 signed bit field, as this assumption is not portable and it makes
11884 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
11885 "char debug_on_exit : 1" as this is not portable either; instead,
11886 use the portable "unsigned int debug_on_exit : 1". Remove unused
11887 member evalargs. Remove obsolete comments about cc bombing out.
11889 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
11891 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

11957 (emacs_fixed_new): Set priv->f to argument.
11958 (emacs_fixed_get_preferred_width)
11959 (emacs_fixed_get_preferred_height): Use min_width/height from
11960 frames size_hint to set minimum and natural (Bug#8919).
11961 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
11962 and use min_width/height from frames size_hint to set
11963 min_width/height (Bug#8919).

12055 * print.c (printchar, strout): Check for string overflow.
12056 (PRINTPREPARE, printchar, strout):
12057 Don't set size unless allocation succeeds.
12059 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12060 for sizes. Check for string overflow more accurately.

12064 * keyboard.h (struct keyboard.kbd_macro_bufsize):
12065 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

12074 (read_integer): Radix is now EMACS_INT, not int,
12075 to improve quality of diagnostics for out-of-range radices.
12076 Calculate buffer size correctly for out-of-range radices.
12077 (read1): Check for integer overflow in radices, and in
12078 read-circle numbers.
12079 (read_escape): Avoid int overflow.
12080 (Fload, openp, read_buffer_size, read1)
12081 (substitute_object_recurse, read_vector, read_list, map_obarray):
12082 Use ptrdiff_t, not int, for sizes.

12102 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12104 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12105 The following patches are for when GLYPH_DEBUG && !XASSERT.
12106 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12107 * dispnew.c (flush_stdout):
12108 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12109 Mark as externally visible.
12110 * dispnew.c (check_window_matrix_pointers): Now static.
12111 * dispnew.c (window_to_frame_vpos):
12112 * xfns.c (unwind_create_frame):
12113 * xterm.c (x_check_font): Remove unused local.
12114 * scroll.c (CHECK_BOUNDS):
12115 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12116 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
12117 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
12118 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
12119 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12121 (debug_method_add): Use va_list and vsprintf rather than relying
12122 on undefined behavior with wrong number of arguments.
12123 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12124 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12125 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12126 since we're not interested in debugging glyphs with old libraries.
12127 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12128 GCC 4.6.0's static checking.
12130 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12132 Integer overflow and signedness fixes (Bug#8873).

12148 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12149 (.bitmaps_last, struct x_output.icon_bitmap):
12150 Use ptrdiff_t, not int, for bitmap indexes.
12151 (x_allocate_bitmap_record): Check for size overflow.
12152 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12154 Use ptrdiff_t, not int, for overlay counts.

12162 (Fnext_overlay_change, Fprevious_overlay_change)
12163 (mouse_face_overlay_overlaps, Foverlays_in):
12164 Use ptrdiff_t, not int, for sizes.
12165 (overlays_at, overlays_in): Check for size-calculation overflow.
12167 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12169 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12170 (x_session_initialize): Do not assume string length fits in int.
12172 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12173 This is unlikely, but can occur if DPI is outlandish.
12175 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12176 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12178 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12179 * xrdb.c (magic_file_p, search_magic_path):
12180 Omit last arg SUFFIX; it was always 0. All callers changed.
12181 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12183 * xfont.c (xfont_match): Avoid need for strlen.
12185 * xfns.c: Don't assume strlen fits in int.
12186 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12188 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12189 not unsigned long, as we prefer signed integers. All callers changed.
12190 Detect integer overflow in repeat count.
12191 (message_dolog): Don't assume print length fits in 39 bytes.
12192 (display_mode_element): Don't assume strlen fits in int.
12194 * termcap.c: Don't assume sizes fit in int and never overflow.
12195 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12196 (gobble_line): Check for size-calculation overflow.
12198 * minibuf.c (Fread_buffer):
12199 * lread.c (intern, intern_c_string):

12203 * keyboard.c (parse_tool_bar_item):
12204 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12206 * font.c: Don't assume string length fits in int.
12207 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
12208 Use ptrdiff_t, not int.
12209 (font_intern_prop): Don't assume string length fits in int.
12210 Don't assume integer property fits in fixnum.
12211 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12213 * filelock.c: Fix some buffer overrun and integer overflow issues.
12214 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12215 Reformulate so as not to need the command string.
12216 Invoke gzip -cd rather than gunzip, as it's more portable.
12217 (lock_info_type, lock_file_1, lock_file):
12218 Don't assume pid_t and time_t fit in unsigned long.
12219 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12220 (current_lock_owner): Prefer signed type for sizes.
12221 Use memcpy, not strncpy, where memcpy is what is really wanted.
12222 Don't assume (via atoi) that time_t and pid_t fit in int.
12223 Check for time_t and/or pid_t out of range, e.g., via a network share.
12224 Don't alloca where an auto var works fine.
12226 * fileio.c: Fix some integer overflow issues.
12227 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12228 Don't assume string length fits in int.
12229 (directory_file_name): Don't assume string length fits in long.
12230 (make_temp_name): Don't assume pid fits in int, or that its print
12231 length is less than 20.
12233 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12235 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12237 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12239 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12240 We prefer signed integers, even for size calculations.
12242 * emacs.c: Don't assume string length fits in 'int'.
12243 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12244 (main): Don't invoke strlen when not needed.
12246 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12247 (XD_DEBUG_MESSAGE): Don't waste a byte.
12249 * callproc.c (getenv_internal_1, getenv_internal)
12250 (Fgetenv_internal):
12251 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12253 * lread.c (invalid_syntax): Omit length argument.
12254 All uses changed. This doesn't fix a bug, but it simplifies the
12255 code away from its former Hollerith-constant appearance, and it's
12256 one less 'int' to worry about when looking at integer-overflow issues.
12257 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12259 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12260 This didn't break anything, but it didn't help either.
12261 It's confusing to put a bogus integer in a place where the actual
12262 value does not matter.
12263 (LIST_END_P): Remove unused macro and its bogus comment.
12264 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12266 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12267 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12269 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12270 We prefer signed types, and the value cannot exceed the EMACS_INT
12271 range anyway (because otherwise the length would not be representable).
12272 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12273 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12274 This avoids a GCC warning when WIDE_EMACS_INT.
12276 * indent.c (sane_tab_width): New function.
12277 (current_column, scan_for_column, Findent_to, position_indentation)
12278 (compute_motion): Use it. This is just for clarity.
12279 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12281 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12283 * lisp.h (lint_assume): New macro.
12284 * composite.c (composition_gstring_put_cache):
12285 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12287 * editfns.c, insdel.c:
12288 Omit unnecessary forward decls, to simplify future changes.
12290 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12292 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12294 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12295 Use much-faster test for byte-length change.
12296 Don't assume string byte-length fits in 'int'.
12297 Check that character arg fits in 'int'.
12298 (mapcar1): Declare byte as byte, for clarity.
12300 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12302 * fns.c (concat): Catch string overflow earlier.
12303 Do not rely on integer wraparound.
12305 * dispextern.h (struct it.overlay_strings_charpos)
12306 (struct it.selective): Now EMACS_INT, not int.
12307 * xdisp.c (forward_to_next_line_start)
12308 (back_to_previous_visible_line_start)
12309 (reseat_at_next_visible_line_start, next_element_from_buffer):
12310 Don't arbitrarily truncate the value of 'selective' to int.
12312 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12314 * composite.c: Don't truncate sizes to 'int'.
12315 (composition_gstring_p, composition_reseat_it)
12316 (composition_adjust_point): Use EMACS_INT, not int.
12317 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12318 not EMACS_UINT, for indexes.
12320 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12322 * buffer.c: Include <verify.h>.
12323 (struct sortvec.priority, struct sortstr.priority):
12324 Now EMACS_INT, not int.
12325 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12326 (struct sortstr.size, record_overlay_string)
12327 (struct sortstrlist.size, struct sortlist.used):
12328 Don't truncate size to int.
12329 (record_overlay_string): Check for size-calculation overflow.
12330 (init_buffer_once): Check at compile-time, not run-time.
12332 2011-06-22 Jim Meyering <meyering@redhat.com>
12334 Don't leak an XBM-image-sized buffer
12335 * image.c (xbm_load): Free the image buffer after using it.
12337 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12340 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12341 that Sun C diagnosed.
12342 * fns.c (secure_hash): Fix pointer signedness issue.
12343 * intervals.c (static_offset_intervals): New function.
12344 (offset_intervals): Use it.
12346 2011-06-21 Leo Liu <sdl.web@gmail.com>
12349 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12352 * fns.c (secure_hash): Rename from crypto_hash_function and change
12353 the first arg to accept symbols.
12354 (Fsecure_hash): New primitive.
12355 (syms_of_fns): New symbols.
12357 2011-06-20 Deniz Dogan <deniz@dogan.se>
12359 * process.c (Fset_process_buffer): Clarify return value in
12362 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12364 * dispnew.c (add_window_display_history): Use BVAR.
12366 * xdisp.c (debug_method_add): Use BVAR.
12367 (check_window_end, dump_glyph_matrix, dump_glyph)
12368 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12370 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12373 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12374 check till after the cache is created in init_frame_faces.
12376 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12378 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12380 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12382 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12383 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12384 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12386 Improve buffer-overflow checking (Bug#8873).
12387 * fileio.c (Finsert_file_contents):
12388 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12389 Remove the old (too-loose) buffer overflow checks.
12390 They weren't needed, since make_gap checks for buffer overflow.
12391 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12392 The old code merely checked for Emacs fixnum overflow, and relied
12393 on undefined (wraparound) behavior. The new code avoids undefined
12394 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12396 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12397 Tune. Don't use wider integers than needed. Don't use alloca.
12398 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12400 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12402 * insdel.c, lisp.h (buffer_overflow): New function.
12403 (insert_from_buffer_1, replace_range, replace_range_2):
12404 * insdel.c (make_gap_larger):
12405 * editfns.c (Finsert_char):
12406 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12408 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12410 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12412 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12414 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12415 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12417 * fileio.c: Don't assume EMACS_INT fits in off_t.
12418 (emacs_lseek): New static function.
12419 (Finsert_file_contents, Fwrite_region): Use it.
12420 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12422 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12424 * fns.c: Don't overflow int when computing a list length.
12425 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12426 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12427 truncation on 64-bit hosts. Check for QUIT every
12428 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12429 faster and is responsive enough.
12430 (Flength): Report an error instead of overflowing an integer.
12431 (Fsafe_length): Return a float if the value is not representable
12432 as a fixnum. This shouldn't happen except in contrived situations.
12433 (Fnthcdr, Fsort): Don't assume list length fits in int.
12434 (Fcopy_sequence): Don't assume vector length fits in int.
12436 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12437 (header_size, word_size): New constants.
12438 (allocate_vectorlike): Don't check size overflow here.
12439 (allocate_vector): Check it here instead, since this is the only
12440 caller of allocate_vectorlike that could cause overflow.
12441 Check that the new vector's length is representable as a fixnum.
12443 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12444 The previous code was bogus. For example, next_almost_prime (32)
12445 returned 39, which is undesirable as it is a multiple of 3; and
12446 next_almost_prime (24) returned 25, which is a multiple of 5 so
12447 why was the code bothering to check for multiples of 7?
12449 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12451 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12453 Variadic C functions now count arguments with ptrdiff_t.
12454 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12455 Back then I didn't know that the Emacs coding style prefers signed int.
12456 Also, in the meantime I found a few more instances where arguments
12457 were being counted with int, which may truncate counts on 64-bit
12458 machines, or EMACS_INT, which may be unnecessarily wide.
12459 * lisp.h (struct Lisp_Subr.function.aMANY)
12460 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12461 Arg counts are now ptrdiff_t, not size_t.
12462 All variadic functions and their callers changed accordingly.
12463 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12464 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12465 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12466 * callint.c (Fcall_interactively): Check arg count for overflow,
12467 to avoid potential buffer overrun. Use signed char, not 'int',
12468 for 'varies' array, so that we needn't bother to check its size
12469 calculation for overflow.
12470 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12471 * eval.c (apply_lambda):
12472 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12473 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12474 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12476 * callint.c (Fcall_interactively): Don't use index var as event count.
12478 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12479 * mem-limits.h (SIZE): Remove; no longer used.
12481 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12483 Remove unnecessary casts.
12484 * xterm.c (x_term_init):
12485 * xfns.c (x_set_border_pixel):
12486 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12487 These aren't needed now that we assume ANSI C.
12489 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12490 It's more likely to cause problems (due to unsigned overflow)
12493 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12495 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12497 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12499 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12501 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12503 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12505 GLYPH_CODE_FACE returns EMACS_INT, not int.
12506 * dispextern.h (merge_faces):
12507 * xfaces.c (merge_faces):
12508 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12509 Don't assume EMACS_INT fits in int.
12511 * character.h (CHAR_VALID_P): Remove unused parameter.
12512 * fontset.c, lisp.h, xdisp.c: All uses changed.
12514 * editfns.c (Ftranslate_region_internal): Omit redundant test.
12516 * fns.c (concat): Minor tuning based on overflow analysis.
12517 This doesn't fix any bugs. Use int to hold character, instead
12518 of constantly refetching from Emacs object. Use XFASTINT, not
12519 XINT, for value known to be a character. Don't bother comparing
12520 a single byte to 0400, as it's always less.
12522 * floatfns.c (Fexpt):
12523 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
12525 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
12528 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
12530 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
12531 Without this fix, on a 64-bit host (aset S 0 4294967386) would
12532 incorrectly succeed when S was a string, because 4294967386 was
12533 truncated before it was used.
12535 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
12536 Otherwise, an out-of-range integer could cause undefined behavior
12539 * composite.c: Use int, not EMACS_INT, for characters.
12540 (fill_gstring_body, composition_compute_stop_pos): Use int, not
12541 EMACS_INT, for values that are known to be in character range.
12542 This doesn't fix any bugs but is the usual style inside Emacs and
12543 may generate better code on 32-bit machines.
12545 Make sure a 64-bit char is never passed to ENCODE_CHAR.
12546 This is for reasons similar to the recent CHAR_STRING fix.
12547 * charset.c (Fencode_char): Check that character arg is actually
12548 a character. Pass an int to ENCODE_CHAR.
12549 * charset.h (ENCODE_CHAR): Verify that the character argument is no
12550 wider than 'int', as a compile-time check to prevent future regressions
12553 * character.c (char_string): Remove unnecessary casts.
12555 Make sure a 64-bit char is never passed to CHAR_STRING.
12556 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
12557 by silently ignoring the top 32 bits, allowing some values
12558 that were far too large to be valid characters.
12559 * character.h: Include <verify.h>.
12560 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
12561 arguments are no wider than unsigned, as a compile-time check
12562 to prevent future regressions in this area.
12564 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
12565 (Fsubst_char_in_region):
12567 * xdisp.c (decode_mode_spec_coding):
12568 Adjust to CHAR_STRING's new requirement.
12569 * editfns.c (Finsert_char, Fsubst_char_in_region):
12570 * fns.c (concat): Check that character args are actually
12571 characters. Without this test, these functions did the wrong
12572 thing with wildly out-of-range values on 64-bit hosts.
12574 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
12575 These casts should not be needed on 32-bit hosts, either.
12576 * keyboard.c (read_char):
12577 * lread.c (Fload): Remove casts to unsigned.
12579 * lisp.h (UNSIGNED_CMP): New macro.
12580 This fixes comparison bugs on 64-bit hosts.
12581 (ASCII_CHAR_P): Use it.
12582 * casefiddle.c (casify_object):
12583 * character.h (ASCII_BYTE_P, CHAR_VALID_P)

12637 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
12638 when a (possibly-narrower) signed value would do just as well.
12639 We prefer using signed arithmetic, to avoid comparison confusion.
12641 * alloc.c: Catch some string size overflows that we were missing.
12642 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
12643 for convenience in STRING_BYTES_MAX.
12644 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
12645 The definition here is exact; the one in lisp.h was approximate.
12646 (allocate_string_data): Check for string overflow. This catches
12647 some instances we weren't catching before. Also, it catches
12648 size_t overflow on (unusual) hosts where SIZE_MAX <= min
12649 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
12650 and ptrdiff_t and EMACS_INT are both 64 bits.
12652 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
12653 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

13231 instead of using explicit *_CHAR codes.
13232 (bidi_resolve_explicit, bidi_resolve_weak):

13242 next/previous character if nothing is cached there yet, or if we
13243 were just reseat()'ed to a new position.
13245 * xdisp.c (set_cursor_from_row): Set start and stop points
13246 according to the row's direction when priming the loop that looks
13247 for the glyph on which to display cursor.

13249 (display_prop_intangible_p): Reimplement to call
13250 handle_display_spec instead of single_display_spec_intangible_p.
13251 Accept 3 additional arguments needed by handle_display_spec.

13261 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13262 value of a `display' property is a "replacing spec".
13263 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13264 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13265 the display property, but just return a value indicating whether
13266 the display property will replace the characters it covers.
13267 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13268 frame_window_p members of struct bidi_it.

13294 * gnutls.c: Use Emacs's memory allocators.
13295 Without this change, the gnutls library would invoke malloc etc.
13296 directly, which causes problems on non-SYNC_INPUT hosts, and which
13297 runs afoul of improving memory_full behavior. (Bug#8761)
13298 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13299 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13300 xfree instead of the default malloc, realloc, free.
13301 (Fgnutls_boot): No need to check for memory allocation failure,
13302 since xmalloc does that for us.

13325 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13326 * alloc.c (allocate_vectorlike):
13327 Check for overflow in vector size calculations.
13328 * ccl.c (ccl_driver):
13329 Check for overflow when converting EMACS_INT to int.

13331 need to be updated by these changes.
13332 * fns.c (make_hash_table, maybe_resize_hash_table):
13333 Check for integer overflow with large hash tables.
13334 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13335 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13336 (SXHASH_REDUCE): New macro.
13337 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13338 Use it instead of discarding useful hash info with large hash values.
13339 (sxhash_float): New function.
13340 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13341 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13342 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13343 Rewrite to use FIXNUM_BITS, as this simplifies things.
13344 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13345 Adjust signatures to match updated version of code.
13346 (consing_since_gc): Now EMACS_INT, since a single hash table can
13347 use more than INT_MAX bytes.

13396 Make it possible to run ./temacs.
13398 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,

13457 2011-05-28 Jim Meyering <meyering@redhat.com>
13459 Avoid a sign-extension bug in crypto_hash_function.
13460 * fns.c (to_uchar): Define.
13461 (crypto_hash_function): Use it to convert some newly-signed
13462 variables to unsigned, to avoid sign-extension bugs. For example,
13463 without this change, (md5 "truc") would evaluate to
13464 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13465 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13466 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13468 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13470 Integer overflow fixes.
13472 * dbusbind.c: Serial number integer overflow fixes.
13473 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13474 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13475 to hold a serial number that is too large for a fixnum.
13476 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13477 Check for serial numbers out of range. Decode any serial number
13478 that was so large that it became a float. (Bug#8722)
13480 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13481 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13482 Use XFASTINT rather than XUINT when numbers are nonnegative.
13483 (xd_append_arg, Fdbus_method_return_internal):
13484 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13485 arguments, check that Lisp number is nonnegative, rather than
13486 silently wrapping negative numbers around. (Bug#8722)
13487 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13490 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13492 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13494 ccl: Add integer overflow checks.
13495 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13496 (IN_INT_RANGE): New macros.
13497 (ccl_driver): Use them to check for integer overflow when
13498 decoding a CCL program. Many of the new checks are whether XINT (x)
13499 fits in int; it doesn't always, on 64-bit hosts. The new version
13500 doesn't catch all possible integer overflows, but it's an
13501 improvement. (Bug#8719)
13503 * alloc.c (make_event_array): Use XINT, not XUINT.
13504 There's no need for unsigned here.
13506 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13507 This follows up to the 2011-05-06 change that substituted uintptr_t
13508 for EMACS_INT. This case wasn't caught back then.
13510 Rework Fformat to avoid integer overflow issues.
13511 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13512 now (part of C89). Include <verify.h>.
13513 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
13514 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
13515 (Fformat): Avoid the prepass trying to compute sizes; it was only
13516 approximate and thus did not catch overflow reliably. Instead, walk
13517 through the format just once, formatting and computing sizes as we go,
13518 checking for integer overflow at every step, and allocating a larger
13519 buffer as needed. Keep track separately whether the format is
13520 multibyte. Keep only the most-recently calculated precision, rather
13521 than them all. Record whether each argument has been converted to
13522 string. Use EMACS_INT, not int, for byte and char and arg counts.
13523 Support field widths and precisions larger than INT_MAX. Avoid
13524 sprintf's undefined behavior with conversion specifications such as %#d
13525 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
13526 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
13527 formatting out-of-range floating point numbers with int
13528 formats. (Bug#8668)
13530 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
13532 * data.c: Avoid integer truncation in expressions involving floats.
13533 * data.c: Include <intprops.h>.
13534 (arith_driver): When there's an integer overflow in an expression
13535 involving floating point, convert the integers to floating point
13536 so that the resulting value does not suffer from catastrophic
13537 integer truncation. For example, on a 64-bit host (* 4
13538 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
13539 Do not rely on undefined behavior after integer overflow.
13541 merge count_size_as_multibyte, parse_str_to_multibyte
13542 * character.c, character.h (count_size_as_multibyte):
13543 Rename from parse_str_to_multibyte; all uses changed.
13544 Check for integer overflow.
13545 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
13546 since it's now a duplicate of the other. This is more of
13547 a character than a buffer op, so better that it's in character.c.
13548 * fns.c, print.c: Adjust to above changes.
13550 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
13552 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
13554 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13556 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13557 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
13558 (x_clipboard_manager_save): Now static.
13559 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
13561 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
13562 (crypto_hash_function): Now static.
13563 Fix pointer signedness problems. Avoid unnecessary initializations.
13565 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
13567 * termhooks.h (Vselection_alist): Make it terminal-local.
13569 * terminal.c (create_terminal): Initialize it.
13571 * xselect.c: Support for clipboard managers.
13572 (Vselection_alist): Move to termhooks.h as terminal-local var.
13573 (LOCAL_SELECTION): New macro.
13574 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
13575 (symbol_to_x_atom): Remove gratuitous arg.
13576 (x_handle_selection_request, lisp_data_to_selection_data)
13577 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
13578 (x_own_selection, x_get_local_selection, x_convert_selection):
13579 New arg, specifying work frame. Use terminal-local Vselection_alist.
13580 (some_frame_on_display): Delete unused function.
13581 (Fx_own_selection_internal, Fx_get_selection_internal)
13582 (Fx_disown_selection_internal, Fx_selection_owner_p)
13583 (Fx_selection_exists_p): New optional frame arg.
13584 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
13585 (x_handle_selection_clear): Don't treat other terminals with the
13586 same keyboard specially. Use the terminal-local Vselection_alist.
13587 (x_clear_frame_selections): Use Frun_hook_with_args.
13589 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
13591 * xterm.h: Add support for those atoms.
13593 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
13595 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
13596 (converted_selections, conversion_fail_tag): New global variables.
13597 (x_selection_request_lisp_error): Free the above.
13598 (x_get_local_selection): Remove unnecessary code.
13599 (x_reply_selection_request): Args changed; handle arbitrary array
13600 of converted selections stored in converted_selections.
13601 Separate the XChangeProperty and SelectionNotify steps.
13602 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
13603 (x_convert_selection): New function.
13604 (x_handle_selection_event): Simplify.
13605 (x_get_foreign_selection): Don't ignore incoming requests while
13606 waiting for an answer; this will fail when we implement
13607 SAVE_TARGETS, and seems unnecessary anyway.
13608 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
13609 (Vx_sent_selection_functions): Doc fix.
13611 2011-05-26 Leo Liu <sdl.web@gmail.com>
13613 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
13615 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13617 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
13619 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
13620 for fringe update if it has periodic bitmap.
13621 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
13622 and fringe_bitmap_periodic_p.
13624 * fringe.c (get_fringe_bitmap_data): New function.
13625 (draw_fringe_bitmap_1, update_window_fringes): Use it.
13626 (update_window_fringes): Record periodicity of fringe bitmap in glyph
13627 row. Mark glyph row for fringe update if periodicity changed.
13629 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
13630 for fringe update unless it has periodic bitmap.
13632 2011-05-25 Kenichi Handa <handa@m17n.org>
13634 * xdisp.c (get_next_display_element): Set correct it->face_id for
13635 a static composition.
13637 2011-05-24 Leo Liu <sdl.web@gmail.com>
13640 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
13642 * fns.c (crypto_hash_function, Fsha1): New function.
13643 (Fmd5): Use crypto_hash_function.
13644 (syms_of_fns): Add Ssha1.
13646 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13648 * gnutls.c: Remove unused macros.
13649 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
13650 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
13651 Remove macros that are defined and never used.
13652 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
13654 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13656 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
13657 (Fx_get_selection_internal): Minor cleanup.
13658 (Fx_own_selection_internal): Rename arguments for consistency with
13661 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
13663 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
13665 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
13667 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
13669 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13671 * dispnew.c (scrolling_window): Don't exclude the case that the
13672 last enabled row in the desired matrix touches the bottom boundary.
13674 2011-05-21 Glenn Morris <rgm@gnu.org>
13676 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
13677 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
13678 and add some more files.
13680 2011-05-20 Eli Zaretskii <eliz@gnu.org>
13682 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
13683 report_file_error introduced by the change from 2011-05-07.
13685 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
13687 * systime.h (Time): Define only if emacs is defined.
13688 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
13689 where the include path doesn't have X11/X.h by default. See
13690 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
13692 2011-05-20 Kenichi Handa <handa@m17n.org>
13694 * composite.c (find_automatic_composition): Fix previous change.
13696 2011-05-20 Glenn Morris <rgm@gnu.org>
13698 * lisp.mk: New file, split from Makefile.in.
13699 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
13700 (shortlisp): Remove.
13701 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
13703 2011-05-19 Glenn Morris <rgm@gnu.org>
13705 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
13706 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
13707 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
13708 (lisp): Set the order to that of loadup.el.
13709 (shortlisp): Make it a copy of $lisp.
13710 (SOME_MACHINE_LISP): Remove.
13711 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
13712 Use just $shortlisp, not $SOME_MACHINE_LISP too.
13714 2011-05-18 Kenichi Handa <handa@m17n.org>
13716 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
13717 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
13718 (find_automatic_composition): Mostly rewrite for efficiency.
13720 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
13722 * makefile.w32-in: Update dependencies.
13724 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
13726 * menu.c: Include limits.h (fixes the MS-Windows build broken by
13727 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
13729 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
13731 Fix some integer overflow issues, such as string length overflow.
13733 * insdel.c (count_size_as_multibyte): Check for string overflow.
13735 * character.c (lisp_string_width): Check for string overflow.
13736 Use EMACS_INT, not int, for string indexes and lengths; in
13737 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
13738 the resulting string length overflows an EMACS_INT; instead,
13739 report a string overflow if no precision given. When checking for
13740 precision exhaustion, use a check that cannot possibly have
13741 integer overflow. (Bug#8675)
13742 * character.h (lisp_string_width): Adjust to new signature.
13744 * alloc.c (string_overflow): New function.
13745 (Fmake_string): Use it. This doesn't change behavior, but saves
13746 a few bytes and will simplify future changes.
13747 * character.c (string_escape_byte8): Likewise.
13748 * lisp.h (string_overflow): New decl.
13750 Fixups, following up to the user-interface timestamp change.
13751 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
13752 for UI timestamps, instead of unsigned long.
13753 * msdos.c (mouse_get_pos): Likewise.
13754 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
13755 * w32gui.h (Time): Define by including "systime.h" rather than by
13756 declaring it ourselves. (Bug#8664)
13758 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
13759 * image.c (clear_image_cache): Likewise.
13761 * term.c (term_mouse_position): Don't assume time_t wraparound.
13763 Be more systematic about user-interface timestamps.
13764 Before, the code sometimes used 'Time', sometimes 'unsigned long',
13765 and sometimes 'EMACS_UINT', to represent these timestamps.
13766 This change causes it to use 'Time' uniformly, as that's what X uses.
13767 This makes the code easier to follow, and makes it easier to catch
13768 integer overflow bugs such as Bug#8664.
13769 * frame.c (Fmouse_position, Fmouse_pixel_position):
13770 Use Time, not unsigned long, for user-interface timestamps.
13771 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
13772 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
13773 * keyboard.h (last_event_timestamp): Likewise.
13774 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
13775 * menu.h (xmenu_show): Likewise.
13776 * term.c (term_mouse_position): Likewise.
13777 * termhooks.h (struct input_event.timestamp): Likewise.
13778 (struct terminal.mouse_position_hook): Likewise.
13779 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
13780 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
13781 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
13782 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
13783 what it was before.
13784 * menu.h, termhooks.h: Include "systime.h", for Time.
13786 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
13787 Don't assume that the difference between two unsigned long values
13788 can fit into an integer. At this point, we know button_down_time
13789 <= event->timestamp, so the difference must be nonnegative, so
13790 there's no need to cast the result if double-click-time is
13791 nonnegative, as it should be; check that it's nonnegative, just in
13792 case. This bug is triggered when events are more than 2**31 ms
13793 apart (about 25 days). (Bug#8664)
13795 * xselect.c (last_event_timestamp): Remove duplicate decl.
13796 (x_own_selection): Remove needless cast to unsigned long.
13798 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
13799 that always fit in int. Use a sentinel instead of a counter, to
13800 avoid a temp and to allay GCC's concerns about possible int overflow.
13801 * frame.h (struct frame): Use int for menu_bar_items_used
13802 instead of EMACS_INT, since it always fits in int.
13804 * menu.c (grow_menu_items): Check for int overflow.
13806 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
13808 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
13809 Before, the code was not consistent. These values cannot exceed
13810 2**31 - 1 so there's no need to make them unsigned.
13811 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
13812 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
13813 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
13815 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
13817 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
13818 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
13819 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
13820 presumably because the widths might not match.
13822 * window.c (size_window): Avoid needless test at loop start.
13824 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
13826 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
13828 2011-05-12 Drew Adams <drew.adams@oracle.com>
13830 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
13832 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13834 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
13835 `width' to `bar_area_x' and `bar_area_width', respectively.
13836 (x_scroll_run): Take account of fringe background extension.
13838 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
13839 Rename local vars `left' and `width' to `bar_area_x' and
13840 `bar_area_width', respectively.
13841 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
13842 background extension.
13844 2011-05-10 Jim Meyering <meyering@redhat.com>
13846 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
13848 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
13850 * image.c (Finit_image_library): Return t for built-in image types,
13851 like pbm and xbm. (Bug#8640)
13853 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
13855 * w32menu.c (set_frame_menubar): Fix submenu allocation.
13857 2011-05-07 Eli Zaretskii <eliz@gnu.org>
13859 * w32console.c (Fset_screen_color): Doc fix.
13860 (Fget_screen_color): New function.
13861 (syms_of_ntterm): Defsubr it.
13863 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
13864 unlink the temporary file if Fcall_process didn't create it in the
13866 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
13867 child process will be redirected to a file specified with `:file'.
13868 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
13869 cue to call_process_cleanup not to close that handle.
13871 2011-05-07 Ben Key <bkey76@gmail.com>
13873 * makefile.w32-in: The bootstrap-temacs rule now makes use of
13874 one of two shell specific rules, either bootstrap-temacs-CMD or
13875 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
13876 to the previous implementation of the bootstrap-temacs rule.
13877 The bootstrap-temacs-CMD rule is similar to the previous
13878 implementation of the bootstrap-temacs rule except that it
13879 makes use of the ESC_CFLAGS variable instead of the CFLAGS
13882 These changes, along with some changes to nt/configure.bat,
13883 nt/gmake.defs, and nt/nmake.defs, are required to extend my
13884 earlier fix to add support for --cflags and --ldflags options
13885 that include quotes so that it works whether make uses cmd or
13888 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
13890 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
13891 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
13893 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
13894 a string. Handle both cases.
13895 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
13896 (Fdbus_register_method): Use Qinvalid_function.
13898 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
13900 * makefile.w32-in: Update dependencies.
13901 (LISP_H): Add inttypes.h and stdin.h.
13902 (PROCESS_H): Add unistd.h.
13904 2011-05-06 Eli Zaretskii <eliz@gnu.org>
13906 * lread.c: Include limits.h (fixes the MS-Windows build broken by
13907 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
13909 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
13911 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
13913 * term.c (vfatal): Remove stray call to va_end.
13914 It's not needed and the C Standard doesn't allow it here anyway.
13916 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
13917 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
13919 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
13922 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
13924 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13926 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
13928 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
13930 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
13932 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
13933 * charset.c (Fdefine_charset_internal): Don't initialize
13934 charset.code_space[15]. The value was garbage, on hosts with
13935 32-bit int (Bug#8600).
13937 * lread.c (read_integer): Be more consistent with string-to-number.
13938 Use string_to_number to do the actual conversion; this avoids
13939 rounding errors and fixes some other screwups. Without this fix,
13940 for example, #x1fffffffffffffff was misread as -2305843009213693952.
13941 (digit_to_number): Move earlier, for benefit of read_integer.
13942 Return -1 if the digit is out of range for the base, -2 if it is
13943 not a digit in any supported base. (Bug#8602)
13945 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
13947 * dispnew.c (scrolling_window): Return 1 if we scrolled,
13948 to match comment at start of function. This also removes a
13949 GCC warning about overflow in a 32+64-bit port.
13951 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
13953 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
13954 Reported by Stefan Monnier in
13955 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
13956 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13957 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
13959 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
13960 (EMACS_UINTPTR): Likewise, with uintptr_t.
13962 * lisp.h: Prefer 64-bit EMACS_INT if available.
13963 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
13964 on 32-bit hosts that have 64-bit int, so that they can access
13966 However, temporarily disable this change unless the temporary
13967 symbol WIDE_EMACS_INT is defined.
13969 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
13971 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
13972 This removes an assumption that EMACS_INT and long are the same
13973 width as pointers. The assumption is true for Emacs porting targets
13974 now, but we want to make other targets possible.
13975 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
13976 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
13977 In the rest of the code, change types of integers that hold casted
13978 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
13979 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
13980 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
13981 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
13982 No need to cast type when ORing.
13983 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
13984 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
13985 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
13986 assume EMACS_INT is the same width as char *.
13987 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
13988 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
13989 Remove no-longer-needed casts.
13990 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
13991 (xg_tool_bar_help_callback, xg_make_tool_item):
13992 Use EMACS_INTPTR to hold an integer
13993 that will be cast to void *; this can avoid a GCC warning
13994 if EMACS_INT is not the same width as void *.
13995 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
13996 * xdisp.c (display_echo_area_1, resize_mini_window_1):
13997 (current_message_1, set_message_1):
13998 Use a local to convert to proper width without a cast.
13999 * xmenu.c (dialog_selection_callback): Likewise.
14001 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14002 Also, don't assume VALBITS / RAND_BITS is less than 5,
14003 and don't rely on undefined behavior when shifting a 1 left into
14005 * lisp.h (get_random): Change signature to match.
14007 * lread.c (hash_string): Use size_t, not int, for hash computation.
14008 Normally we prefer signed values; but hashing is special, because
14009 it's better to use unsigned division on hash table sizes so that
14010 the remainder is nonnegative. Also, size_t is the natural width
14011 for hashing into memory. The previous code used 'int', which doesn't
14012 retain enough info to hash well into very large tables.
14013 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14015 * dbusbind.c: Don't possibly lose pointer info when converting.
14016 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14017 Use XPNTR rather than XHASH, so that the high-order bits of
14018 the pointer aren't lost when converting through void *.
14020 * eval.c (Fautoload): Don't double-shift a pointer.
14022 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14024 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14026 * gnutls.c (DEF_GNUTLS_FN):
14027 * image.c (DEF_IMGLIB_FN): Make function pointers static.
14029 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
14031 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
14034 2011-05-05 Eli Zaretskii <eliz@gnu.org>
14036 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
14037 New version that can reserve upto 2GB of heap space.
14039 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
14041 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
14043 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
14045 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
14046 `gnutls_certificate_set_x509_key_file'.
14048 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
14050 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
14051 Update dependencies.
14053 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14055 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
14056 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14057 Remove unused parameter `fildes'.
14058 * process.c (read_process_output, send_process): Don't pass it.
14060 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14062 Fix previous change: the library cache is defined in w32.c.
14063 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
14064 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
14066 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
14068 Implement dynamic loading of GnuTLS on Windows.
14070 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
14071 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
14072 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14075 * gnutls.c (Qgnutls_dll): Define.
14076 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
14077 (gnutls_*): Declare function pointers.
14078 (init_gnutls_functions): New function to initialize function pointers.

14081 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
14082 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
14083 (emacs_gnutls_write, emacs_gnutls_read)
14084 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
14085 (Fgnutls_available_p): New function.
14086 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

14098 * w32.c (QCloaded_from, Vlibrary_cache): Define.
14099 (w32_delayed_load): Move from image.c. When loading a library, record
14100 its filename in the :loaded-from property of the library id.
14101 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
14102 Initialize and staticpro them.
14103 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
14105 * process.c: Include lisp.h before w32.h, not after.
14106 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
14107 instead of gnutls_record_check_pending.
14109 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
14111 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
14113 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
14114 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
14117 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
14119 * xterm.c (x_set_frame_alpha): Do not set property on anything
14120 else than FRAME_X_OUTER_WINDOW (Bug#8608).
14122 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14124 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
14126 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
14128 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

14142 * sysdep.c (wait_for_termination_1): Make static.
14143 (wait_for_termination, interruptible_wait_for_termination):
14144 Move after wait_for_termination_1.
14146 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
14148 * sysdep.c (interruptible_wait_for_termination): New function
14149 which is like wait_for_termination, but allows keyboard
14152 * callproc.c (Fcall_process): Add (:file "file") as an option for
14154 (Fcall_process_region): Ditto.
14156 2011-04-30 Eli Zaretskii <eliz@gnu.org>
14158 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
14159 rather than `XVECTOR (FOO)->size'.
14161 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
14162 inttypes.h, as a gnulib replacement is used if it not available in
14165 2011-04-21 Eli Zaretskii <eliz@gnu.org>
14167 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
14168 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
14169 of MOST_POSITIVE_FIXNUM. (Bug#8528)
14171 * coding.c (coding_alloc_by_realloc): Error out if destination
14172 will grow beyond MOST_POSITIVE_FIXNUM.
14173 (decode_coding_emacs_mule): Abort if there isn't enough place in
14174 charbuf for the composition carryover bytes. Reserve an extra
14175 space for up to 2 characters produced in a loop.
14176 (decode_coding_iso_2022): Abort if there isn't enough place in

14184 %llo or %llx format is passed. (Bug#8545)
14186 * window.c (window_scroll_line_based): Use a marker instead of
14187 simple variables to record original value of point. (Bug#7952)
14189 * doprnt.c (doprnt): Fix the case where a multibyte sequence
14190 produced by %s or %c overflows available buffer space. (Bug#8545)
14192 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>

14227 2011-04-27 Eli Zaretskii <eliz@gnu.org>
14229 Improve `doprnt' and its usage. (Bug#8545)
14230 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14231 `format_end'. Remove support for %l as a conversion specifier.
14232 Don't use xrealloc. Improve diagnostics when the %l size modifier
14233 is used. Update the commentary.
14235 * eval.c (verror): Simplify calculation of size_t.
14237 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14240 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14242 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14245 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14247 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14248 This makes this file independent of the recent pseudovector change.
14250 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14252 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14254 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14255 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14256 Remove unused local.
14257 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14259 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14260 GCC 4.6.0 optimizes based on type-based alias analysis.
14261 For example, if b is of type struct buffer * and v of type struct
14262 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14263 != &v->size, and therefore "v->size = 1; b->size = 2; return
14264 v->size;" must therefore return 1. This assumption is incorrect
14265 for Emacs, since it type-puns struct Lisp_Vector * with many other
14266 types. To fix this problem, this patch adds a new type struct
14267 vectorlike_header that documents the constraints on layout of vectors
14268 and pseudovectors, and helps optimizing compilers not get fooled
14269 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14270 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14271 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14273 (XSETPVECTYPE): Rewrite in terms of new macro.
14274 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14275 This is a bit clearer, and further avoids the possibility of
14276 undesirable aliasing.
14277 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14278 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14279 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14280 since Lisp_Subr is a special case (no "next" field).
14281 (ASIZE): Now uses header.size rather than size.
14282 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14283 to avoid the hassle of writing XVECTOR (foo)->header.size.
14284 (struct vectorlike_header): New type.
14285 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14286 object, to help avoid aliasing.
14287 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14288 (SUBRP): Likewise, since Lisp_Subr is a special case.
14289 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14290 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14291 (struct Lisp_Hash_Table): Combine first two members into a single
14292 struct vectorlike_header member. All uses of "size" and "next" members
14293 changed to be "header.size" and "header.next".
14294 * buffer.h (struct buffer): Likewise.
14295 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14296 * frame.h (struct frame): Likewise.
14297 * process.h (struct Lisp_Process): Likewise.
14298 * termhooks.h (struct terminal): Likewise.
14299 * window.c (struct save_window_data, struct saved_window): Likewise.
14300 * window.h (struct window): Likewise.
14301 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14302 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14303 * buffer.c (init_buffer_once): Likewise.
14304 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14306 * process.c (Fformat_network_address): Use local var for size,
14309 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14311 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14312 * data.c (atof): Remove decl; no longer used or needed.
14313 (digit_to_number): Move to lread.c.
14314 (Fstring_to_number): Use new string_to_number function, to be
14315 consistent with how the Lisp reader treats infinities and NaNs.
14316 Do not assume that floating-point numbers represent EMACS_INT
14317 without losing information; this is not true on most 64-bit hosts.
14318 Avoid double-rounding errors, by insisting on integers when
14319 parsing non-base-10 numbers, as the documentation specifies.
14320 * lisp.h (string_to_number): New decl, replacing ...
14321 (isfloat_string): Remove.
14322 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14323 (read1): Do not accept +. and -. as integers; this
14324 appears to have been a coding error. Similarly, do not accept
14325 strings like +-1e0 as floating point numbers. Do not report
14326 overflow for integer overflows unless the base is not 10 which
14327 means we have no simple and reliable way to continue.
14328 Break out the floating-point parsing into a new
14329 function string_to_number, so that Fstring_to_number parses
14330 floating point numbers consistently with the Lisp reader.
14331 (digit_to_number): Move here from data.c. Make it static inline.
14332 (E_CHAR, EXP_INT): Remove, replacing with ...
14333 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14334 (string_to_number): New function, replacing isfloat_string.
14335 This function checks for valid syntax and produces the resulting
14336 Lisp float number too. Rework it so that string-to-number
14337 no longer mishandles examples like "1.0e+". Use strtoumax,
14338 so that overflow for non-base-10 numbers is reported only when
14339 there's no portable and simple way to convert to floating point.
14341 * textprop.c (set_text_properties_1): Rewrite for clarity,
14342 and to avoid GCC warning about integer overflow.
14344 * intervals.h (struct interval): Use EMACS_INT for members
14345 where EMACS_UINT might cause problems. See
14346 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14347 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14348 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14350 (offset_intervals): Tell GCC not to worry about length overflow
14351 when negating a negative length.
14353 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14354 (overrun_check_free): Likewise.
14356 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14357 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14360 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14361 (gnutls_make_error): Rename local to avoid shadowing.
14362 (gnutls_emacs_global_deinit): ifdef out; not used.
14363 (Fgnutls_boot): Use const for pointer to readonly storage.
14364 Comment out unused local. Fix pointer signedness problems.
14366 * lread.c (openp): Don't stuff size_t into an 'int'.
14367 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14368 about possible signed overflow.
14370 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14371 (GDK_KEY_g): Don't define if already defined.
14372 (xg_prepare_tooltip): Avoid pointer signedness problem.
14373 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14375 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14376 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14378 * xfns.c (Fx_window_property): Simplify a bit,
14379 to make a bit faster and to avoid GCC 4.6.0 warning.
14380 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14382 * fns.c (internal_equal): Don't assume size_t fits in int.
14384 * alloc.c (compact_small_strings): Tighten assertion a little.
14386 Replace pEd with more-general pI, and fix some printf arg casts.
14387 * lisp.h (pI): New macro, generalizing old pEd macro to other
14388 conversion specifiers. For example, use "...%"pI"d..." rather
14389 than "...%"pEd"...".
14390 (pEd): Remove. All uses replaced with similar uses of pI.
14391 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14392 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14393 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14394 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14395 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14396 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
14397 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
14399 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14400 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14401 * print.c (safe_debug_print, print_object): Likewise.
14402 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14404 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14405 avoiding the 0 flag, which is not portable.
14406 * process.c (Fmake_network_process): Use pI to avoid cast.
14407 * region-cache.c (pp_cache): Likewise.
14408 * xdisp.c (decode_mode_spec): Likewise.
14409 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14410 behavior on 64-bit hosts with printf arg.
14411 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
14412 (x_stop_queuing_selection_requests): Likewise.
14413 (x_get_window_property): Don't truncate byte count to an 'int'
14416 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14417 here, since it parses constructs like leading '-' and spaces,
14418 which are not wanted; and it overflows with large numbers.
14419 Instead, simply match F[0-9]+, which is what is wanted anyway.
14421 * alloc.c: Remove unportable assumptions about struct layout.
14422 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14423 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14424 (allocate_vectorlike, make_pure_vector): Use the new macros,
14425 plus offsetof, to remove unportable assumptions about struct layout.
14426 These assumptions hold on all porting targets that I know of, but
14427 they are not guaranteed, they're easy to remove, and removing them
14428 makes further changes easier.
14430 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14431 This doesn't fix a bug but makes the code clearer.
14432 (string_overrun_cookie): Now const. Use initializers that
14433 don't formally overflow signed char, to avoid warnings.
14434 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14435 can cause Emacs to crash when string overrun checking is enabled.
14436 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14437 multiple of sizeof (EMACS_INT); it need not be, if
14438 alignof(EMACS_INT) < sizeof (EMACS_INT).
14439 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14441 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

14448 supposed to be handshaking. (Bug#8556)
14449 Reported by Paul Eggert <eggert@cs.ucla.edu>.
14451 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
14453 * lisp.h (Qdebug): List symbol.
14454 * eval.c (Qdebug): Restore global linkage.

14462 (check_string_free_list): Convert to standard C.
14464 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
14466 * w32.c (emacs_gnutls_push): Fix typo.
14468 2011-04-25 Eli Zaretskii <eliz@gnu.org>
14470 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14471 "cast to pointer from integer of different size".
14473 Improve doprnt and its use in verror. (Bug#8545)
14474 * doprnt.c (doprnt): Document the set of format control sequences
14475 supported by the function. Use SAFE_ALLOCA instead of always
14478 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14479 is one byte too soon. Don't use xrealloc; instead xfree and
14482 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14484 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
14487 * gnutls.c: Renamed global_initialized to
14488 gnutls_global_initialized. Added internals for the
14489 :verify-hostname-error, :verify-error, and :verify-flags
14490 parameters of `gnutls-boot' and documented those parameters in the
14491 docstring. Start callback support.
14492 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14493 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14494 on error. Return error code.

14566 * doprnt.c: Include limits.h.
14567 (SIZE_MAX): New macro.
14568 (doprnt): Return a size_t value. 2nd arg is now size_t.
14569 Many local variables are now size_t instead of int or unsigned.
14570 Improve overflow protection. Support `l' modifier for integer
14571 conversions. Support %l conversion. Don't assume an EMACS_INT
14572 argument for integer conversions and for %c.
14574 * lisp.h (doprnt): Restore prototype.
14576 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
14577 $(SRC)/character.h.
14579 * Makefile.in (base_obj): Add back doprnt.o.
14581 * deps.mk (doprnt.o): Add back prerequisites.
14582 (callint.o): Depend on character.h.
14584 * eval.c (internal_lisp_condition_case): Include the handler
14585 representation in the error message.

14591 * callint.c (Fcall_interactively): When displaying error message
14592 about invalid control letter, pass the character's codepoint, not
14593 a pointer to its multibyte form. Improve display of the character
14594 in octal and display also its hex code.
14596 * character.c (char_string): Use %x to display the (unsigned)
14597 codepoint of an invalid character, to avoid displaying a bogus
14600 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
14601 `error', not SYMBOL_NAME itself.
14603 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
14604 character arguments to `error'.
14606 * charset.c (check_iso_charset_parameter): Fix incorrect argument
14607 to `error' in error message about FINAL_CHAR argument. Make sure
14608 FINAL_CHAR is a character, and use %c when it is passed as

14675 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
14676 by pacifying GCC about it. Maybe it's time to retire it?
14677 * xfaces.c (USG, __TIMEVAL__): Likewise.
14679 * dispextern.h (struct redisplay_interface): Rename param
14680 to avoid shadowing.
14681 * termhooks.h (struct terminal): Likewise.
14682 * xterm.c (xembed_send_message): Likewise.
14684 * insdel.c (make_gap_smaller): Define only if
14685 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
14687 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
14690 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
14691 so that we aren't warned about unused symbols.
14693 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
14695 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

14704 define if USE_GTK || USE_X_TOOLKIT.
14705 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
14706 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

14708 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
14710 * xmenu.c (menu_help_callback): Pointer type fixes.

14728 compatible char. Avoid the old compiler warnings about
14729 out-of-range initializers by using, for example, '\xab' rather
14732 * xgselect.c (xgselect_initialize): Check vs interface
14733 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

14798 * nsfont.m: Fixed bugs in ns_get_family and
14799 ns_descriptor_to_entity that were caused by using free to
14800 deallocate memory blocks that were allocated by xmalloc (via
14801 xstrdup). This caused Emacs to crash when compiled with
14802 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
14803 --enable-checking=xmallocoverrun). xfree is now used to
14804 deallocate these memory blocks.

15200 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
15201 * xmenu.c, xselect.c:
15202 Declare Q* vars static if they are not used in other modules.
15203 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
15204 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15205 Remove decls of unexported vars.
15206 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15208 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15210 Make Emacs functions such as Fatom 'static' by default.
15211 This makes it easier for human readers (and static analyzers)
15212 to see whether these functions can be called from other modules.
15213 DEFUN now defines a static function. To make the function external
15214 so that it can be used in other C modules, use the new macro DEFUE.
15215 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15216 (Finit_image_library):
15217 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15218 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15219 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15220 Remove decls, since these functions are now static.
15221 (Funintern, Fget_internal_run_time): New decls, since these functions
15222 were already external.
15224 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15225 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

15231 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15232 Mark functions with DEFUE instead of DEFUN,
15233 if they are used in other modules.
15234 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15235 decls for now-static functions.
15236 * buffer.h (Fdelete_overlay): Remove decl.
15237 * callproc.c (Fgetenv_internal): Mark as internal.
15238 * composite.c (Fremove_list_of_text_properties): Remove decl.

15242 * doc.c (Fdocumntation_property): New forward static decl.
15243 * eval.c (Ffetch_bytecode): New forward static decl.
15244 (Funintern): Remove extern decl; now in .h file where it belongs.
15245 * fileio.c (Fmake_symbolic_link): New forward static decl.
15246 * image.c (Finit_image_library): New forward static decl.
15247 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15248 * intervals.h (Fprevious_property_change):
15249 (Fremove_list_of_text_properties): Remove decls.
15250 * keyboard.c (Fthis_command_keys): Remove decl.
15251 (Fcommand_execute): New forward static decl.
15252 * keymap.c (Flookup_key): New forward static decl.
15253 (Fcopy_keymap): Now static.
15254 * keymap.h (Flookup_key): Remove decl.
15255 * process.c (Fget_process): New forward static decl.
15256 (Fprocess_datagram_address): Mark as internal.

15267 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15269 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15272 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15274 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15275 when at ZV. (Bug#8487)
15277 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15279 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15281 * keyboard.c (parse_tool_bar_item): Likewise.
15282 * sound.c (sound_cleanup, alsa_close): Likewise.
15283 * termcap.c (tgetent): Likewise.
15284 * xfns.c (x_default_font_parameter): Likewise.
15285 * xsettings.c (read_and_apply_settings): Likewise.
15287 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15288 (overrun_check_free): Protoize.
15290 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15292 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15293 since callers should never pass a negative size.
15294 Change the signature to match that of plain 'read' and 'write'; see
15295 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15296 * lisp.h: Update prototypes of emacs_write and emacs_read.
15298 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15300 * xdisp.c (redisplay_window): Don't try to determine the character
15301 position of the scroll margin if the window start point w->startp
15302 is outside the buffer's accessible region. (Bug#8468)
15304 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15306 Fix write-region and its subroutines for buffers > 2GB.
15307 * fileio.c (a_write, e_write): Modify declaration of arguments and
15308 local variables to support buffers larger than 2GB.
15309 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15311 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15312 argument, local variables, and return value.
15314 * lisp.h: Update prototypes of emacs_write and emacs_read.
15316 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15318 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15320 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15322 Fix more problems found by GCC 4.6.0's static checks.
15324 * xdisp.c (vmessage): Use a better test for character truncation.
15326 * charset.c (load_charset_map): <, not <=, for optimization,
15327 and to avoid potential problems with integer overflow.
15328 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15329 * casetab.c (set_identity, shuffle): Likewise.
15330 * editfns.c (Fformat): Likewise.
15331 * syntax.c (skip_chars): Likewise.
15333 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15334 This also lets GCC 4.6.0 generate slightly better loop code.
15336 * callint.c (Fcall_interactively): <, not <=, for optimization.
15337 (Fcall_interactively): Count the number of arguments produced,
15338 not the number of arguments given. This is simpler and lets GCC
15339 4.6.0 generate slightly better code.
15341 * ftfont.c: Distingish more carefully between FcChar8 and char.
15342 The previous code passed unsigned char * to a functions like
15343 strlen and xstrcasecmp that expect char *, which does not
15344 conform to the C standard.
15345 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15346 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15347 char * when the C standard requires it.
15349 * keyboard.c (read_char): Remove unused var.
15351 * eval.c: Port to Windows vsnprintf (Bug#8435).
15352 Include <limits.h>.
15353 (SIZE_MAX): Define if the headers do not.
15354 (verror): Do not give up if vsnprintf returns a negative count.
15355 Instead, grow the buffer. This ports to Windows vsnprintf, which
15356 does not conform to C99. Problem reported by Eli Zaretskii.
15357 Also, simplify the allocation scheme, by avoiding the need for
15358 calling realloc, and removing the ALLOCATED variable.
15360 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15362 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15363 But keep the doprint source code for now, as we might revamp it
15364 and use it again (Bug#8435).
15365 * lisp.h (doprnt): Remove.
15366 * Makefile.in (base_obj): Remove doprnt.o.
15367 * deps.mk (doprnt.o): Remove.
15369 error: Print 32- and 64-bit integers portably (Bug#8435).
15370 Without this change, on typical 64-bit hosts error ("...%d...", N)
15371 was used to print both 32- and 64-bit integers N, which relied on
15372 undefined behavior.
15373 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15374 * lisp.h (error, verror): Mark as printf-like functions.
15375 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15376 Report overflow in size calculations when allocating printf buffer.
15377 Do not truncate output string at its first null byte.
15378 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15379 Truncate the output at a character boundary, since vsnprintf does not
15381 * charset.c (check_iso_charset_parameter): Convert internal
15382 character to string before calling 'error', since %c now has the
15384 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15385 overflow when computing char to be passed to 'error'. Do not
15386 pass Lisp_Object to 'error'; pass the integer instead.
15387 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15388 formatted with plain %d.
15390 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15392 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15394 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15396 * xterm.c (x_catch_errors): Remove duplicate declaration.
15398 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15400 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15402 2011-04-10 Jim Meyering <meyering@redhat.com>
15404 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15405 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15406 return ssize_t not "int", and use size_t as the buffer length.
15407 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15408 * gnutls.h: Update declarations.
15409 * process.c (read_process_output): Use ssize_t, to match.
15410 (send_process): Likewise.
15412 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15414 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15416 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15418 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15419 Use unsigned char, to match FcChar8 type definition.
15421 * xterm.c (handle_one_xevent):
15422 * xmenu.c (create_and_show_popup_menu):
15423 * xselect.c (x_decline_selection_request)
15424 (x_reply_selection_request): Avoid type-punned deref of X events.
15426 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15428 Fix some uses of `int' instead of EMACS_INT.
15429 * search.c (string_match_1, fast_string_match)
15430 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15431 (scan_buffer, find_next_newline_no_quit)
15432 (find_before_next_newline, search_command, Freplace_match)
15433 (Fmatch_data): Make some `int' variables be EMACS_INT.
15435 * xdisp.c (display_count_lines): 3rd argument and return value now
15436 EMACS_INT. All callers changed.
15437 (pint2hrstr): Last argument is now EMACS_INT.
15439 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15440 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15441 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15442 (decode_coding_utf_16, decode_coding_emacs_mule)
15443 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15444 (decode_coding_ccl, decode_coding_charset)
15445 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15446 (decode_coding_iso_2022, decode_coding_emacs_mule)
15447 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15448 <char_offset, last_offset>: Declare EMACS_INT.

15450 (encode_coding_emacs_mule, encode_invocation_designation)
15451 (encode_designation_at_bol, encode_coding_iso_2022)
15452 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15453 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15455 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15456 (encode_invocation_designation): Last argument P_NCHARS is now
15458 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15459 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15461 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15464 * ccl.c (Fccl_execute_on_string): Declare some variables
15467 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15469 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15471 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15473 * process.c (Fformat_network_address): Doc fix.
15475 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15477 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15479 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15481 * keyboard.c (read_char): Call Lisp function help-form-show,
15482 instead of using internal_with_output_to_temp_buffer.
15483 (Qhelp_form_show): New var.
15484 (syms_of_keyboard): Use DEFSYM macro.
15486 * print.c (internal_with_output_to_temp_buffer): Function deleted.

15490 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15492 * process.c (Flist_processes): Remove to Lisp.
15493 (list_processes_1): Delete.
15495 2011-04-06 Eli Zaretskii <eliz@gnu.org>
15497 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15499 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15501 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15503 Fix more problems found by GCC 4.6.0's static checks.
15505 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15507 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15509 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15511 * xdisp.c (vmessage): Mark as a printf-like function.
15513 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15515 * sound.c (sound_warning): Don't crash if arg contains a printf format.

15520 to system-supplied API.
15522 * eval.c (Fsignal): Remove excess argument to 'fatal'.
15524 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
15525 This avoids several warnings with gcc -Wstrict-overflow.
15526 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
15527 directly, rather than having caller test rule sign. This avoids
15528 some unnecessary tests.
15529 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
15530 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
15531 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
15533 * xfont.c (xfont_text_extents): Remove var that was set but not used.
15534 (xfont_open): Avoid unnecessary tests.
15536 * composite.c (composition_gstring_put_cache): Use unsigned integer.

15545 by using the new macro.
15547 * textprop.c (set_text_properties_1): Change while to do-while,
15548 since the condition is always true at first.
15550 * intervals.c (graft_intervals_into_buffer): Mark var as used.
15551 (interval_deletion_adjustment): Return unsigned value.
15554 * process.c (list_processes_1, create_pty, read_process_output):

15564 (update_syntax_table): Use unsigned instead of int.
15566 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
15567 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
15568 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
15570 * print.c (print_error_message): Avoid int overflow.
15572 * font.c (font_list_entities): Redo for clarity,
15573 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
15575 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
15576 (font_score): Avoid potential overflow in diff calculation.
15578 * fns.c (substring_both): Remove var that is set but not used.
15579 (sxhash): Redo loop for clarity and to avoid wraparound warning.
15581 * eval.c (funcall_lambda): Rename local to avoid shadowing.
15583 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
15584 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
15585 can always succeed if overflow has undefined behavior.
15587 * search.c (boyer_moore, wordify): Remove vars set but not used.
15588 (wordify): Omit three unnecessary tests.
15590 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
15591 All callers changed. This avoids the need for an unused var.
15593 * casefiddle.c (casify_region): Remove var that is set but not used.
15595 * dired.c (file_name_completion): Remove var that is set but not used.

15599 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
15600 (Finsert_file_contents): Remove unnecessary code checking fd.
15602 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
15603 Check for integer overflow on size calculations.
15605 * buffer.c (Fprevious_overlay_change): Remove var that is set
15608 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
15609 Remove vars that are set but not used.
15610 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
15611 (timer_check_2): Mark vars as initialized.
15613 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
15615 * image.c (lookup_image): Remove var that is set but not used.
15616 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
15618 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
15619 that are set but not used.
15621 * xfns.c (make_invisible_cursor): Don't return garbage
15622 if XCreateBitmapFromData fails (Bug#8410).
15624 * xselect.c (x_get_local_selection, x_handle_property_notify):
15625 Remove vars that are set but not used.
15627 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
15628 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
15630 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
15631 Remove var that is set but not used.
15632 (scroll_bar_windows_size): Now size_t, not int.
15633 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
15634 Check for overflow.
15636 * xfaces.c (realize_named_face): Remove vars that are set but not used.
15637 (map_tty_color) [!defined MSDOS]: Likewise.
15639 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
15641 * coding.c: Remove vars that are set but not used.
15642 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

15649 that is set but not used.
15651 * print.c (print_object): Remove var that is set but not used.
15653 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
15654 The gnulib version avoids calling malloc in the usual case,
15655 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
15656 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
15657 * filelock.c (current_lock_owner): Likewise.
15658 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
15659 * sysdep.c: Include allocator.h, careadlinkat.h.
15660 (emacs_no_realloc_allocator): New static constant.
15661 (emacs_readlink): New function.
15662 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
15663 ../lib/careadlinkat.h.
15665 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
15667 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

15689 do not dereference NULL upon failed strdup
15690 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
15691 (ns_get_family): Likewise.
15693 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
15695 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
15697 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
15699 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
15702 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
15704 Add lexical binding.
15706 * window.c (Ftemp_output_buffer_show): New fun.
15707 (Fsave_window_excursion):

15715 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
15717 (syms_of_lread): Declare `lexical-binding'.
15719 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
15721 * keyboard.c (eval_dyn): New fun.
15722 (menu_item_eval_property): Use it.
15724 * image.c (parse_image_spec): Use Ffunctionp.
15726 * fns.c (concat, mapcar1): Accept byte-code-functions.
15728 * eval.c (Fsetq): Handle lexical vars.
15729 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
15730 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
15731 (FletX, Flet): Obey lexical binding.
15732 (Fcommandp): Handle closures.
15733 (Feval): New `lexical' arg.
15734 (eval_sub): New function extracted from Feval. Use it almost
15735 everywhere where Feval was used. Look up vars in lexical env.
15737 (Ffunctionp): Move from subr.el.
15738 (Ffuncall): Handle closures.
15739 (apply_lambda): Remove `eval_flags'.
15740 (funcall_lambda): Handle closures and new byte-code-functions.
15741 (Fspecial_variable_p): New function.
15742 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
15743 but without exporting it to Lisp.
15745 * doc.c (Fdocumentation, store_function_docstring):
15746 * data.c (Finteractive_form): Handle closures.
15748 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
15751 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
15753 (exec_byte_code): New function extracted from Fbyte_code to handle new
15754 calling convention for byte-code-functions. Add new byte-codes.
15756 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
15758 * alloc.c (Fmake_symbol): Init new `declared_special' field.
15760 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
15762 * xdisp.c (redisplay_internal): Fix prototype.
15764 2011-03-31 Eli Zaretskii <eliz@gnu.org>
15766 * xdisp.c (SCROLL_LIMIT): New macro.
15767 (try_scrolling): Use it when setting scroll_limit.
15768 Limit scrolling to 100 screen lines.
15769 (redisplay_window): Even when falling back on "recentering",
15770 position point in the window according to scroll-conservatively,
15771 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
15773 (try_scrolling): When point is above the window, allow searching
15774 as far as scroll_max, or one screenful, to compute vertical
15775 distance from PT to the scroll margin position. This prevents
15776 try_scrolling from unnecessarily failing when
15777 scroll-conservatively is set to a value slightly larger than the
15778 window height. Clean up the case of PT below the margin at bottom
15779 of window: scroll_max can no longer be INT_MAX. When aggressive
15780 scrolling is in use, don't let point enter the opposite scroll
15781 margin as result of the scroll.
15782 (syms_of_xdisp) <scroll-conservatively>: Document the
15783 threshold of 100 lines for never-recentering scrolling.

15790 (message_log_check_duplicate): Remove parameters `prev_bol' and
15791 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
15792 (redisplay_internal): Remove parameter `preserve_echo_area',
15793 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
15795 * indent.c (Fvertical_motion):
15796 * window.c (window_scroll_pixel_based, Frecenter):
15797 Don't pass `need_y_p' to `move_it_by_lines'.
15799 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
15801 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
15802 steal a few bits to be more compact.
15803 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
15804 Remove unneeded casts.
15806 * bytecode.c (Fbyte_code): CAR and CDR can GC.
15808 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
15810 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
15811 binding" message (bug#7967).
15813 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
15815 Fix more problems found by GCC 4.6.0's static checks.
15817 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
15818 Remove unused local var.
15820 * editfns.c (Fmessage_box): Remove unused local var.
15822 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
15823 (note_mode_line_or_margin_highlight, note_mouse_highlight):
15824 Omit unused local vars.
15825 * window.c (shrink_windows): Omit unused local var.
15826 * menu.c (digest_single_submenu): Omit unused local var.
15827 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
15828 Omit unused local var.
15830 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
15831 Don't assume string length fits in int.
15832 (keyremap_step, read_key_sequence): Use size_t for sizes.
15833 (read_key_sequence): Don't check last_real_key_start redundantly.
15835 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
15836 instead of alloca (Bug#8344).
15838 * eval.c (Fbacktrace): Don't assume nargs fits in int.
15839 (Fbacktrace_frame): Don't assume nframes fits in int.
15841 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

15848 * cm.c (calccost): Turn while-do into do-while, for clarity.
15850 * keyboard.c (syms_of_keyboard): Use the same style as later
15851 in this function when indexing through an array. This also
15852 works around GCC bug 48267.
15854 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
15856 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
15858 * chartab.c (sub_char_table_ref_and_range): Redo for slight
15859 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
15861 * keyboard.c, keyboard.h (num_input_events): Now size_t.
15862 This avoids undefined behavior on integer overflow, and is a bit
15863 more convenient anyway since it is compared to a size_t variable.
15865 Variadic C functions now count arguments with size_t, not int.
15866 This avoids an unnecessary limitation on 64-bit machines, which
15867 caused (substring ...) to crash on large vectors (Bug#8344).

15877 * fns.c (concat): Likewise.
15878 * frame.c (x_set_frame_parameters): Likewise.
15879 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
15880 0 if not found, not -1. All callers changed.
15882 * alloc.c (garbage_collect): Don't assume stack size fits in int.
15883 (stack_copy_size): Now size_t, not int.
15884 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
15886 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
15888 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
15889 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

15905 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
15906 don't set the hook to nil, but remove the offending function instead.
15907 (Qcommand_hook_internal): Remove, unused.
15908 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
15909 Vcommand_hook_internal.
15911 * eval.c (enum run_hooks_condition): Remove.
15912 (funcall_nil, funcall_not): New functions.
15913 (run_hook_with_args): Call each function through a `funcall' argument.

15927 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

16077 2011-03-23 Julien Danjou <julien@danjou.info>
16079 * term.c (Fsuspend_tty, Fresume_tty):
16080 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
16081 * window.c (temp_output_buffer_show):
16082 * insdel.c (signal_before_change):
16083 * frame.c (Fhandle_switch_frame):
16084 * fileio.c (Fdo_auto_save):
16085 * emacs.c (Fkill_emacs):
16086 * editfns.c (save_excursion_restore):
16087 * cmds.c (internal_self_insert):
16088 * callint.c (Fcall_interactively):
16089 * buffer.c (Fkill_all_local_variables):
16090 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
16092 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
16093 unconditionally since it does the check itself.
16095 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
16097 Fix more problems found by GCC 4.5.2's static checks.
16099 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16100 the first time through the loop, since we know p0 < p1 then.
16101 This also avoids a gcc -Wstrict-overflow warning.
16103 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16104 leading to a memory leak, possible in functions like
16105 load_charset_map_from_file that can allocate an unbounded number
16106 of objects (Bug#8318).
16108 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16109 that could (at least in theory) be that large.
16111 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16112 This is less likely to overflow, and avoids undefined behavior if
16113 overflow does occur. All callers changed. Use strtoul to scan
16114 for the unsigned long integer.
16115 (pint2hrstr): Simplify and tune code slightly.
16116 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16118 * scroll.c (do_scrolling): Work around GCC bug 48228.
16119 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
16121 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
16122 This also avoids a warning with gcc -Wstrict-overflow.
16123 (validate_x_resource_name): Simplify count usage.
16124 This also avoids a warning with gcc -Wstrict-overflow.
16126 * fileio.c (Fcopy_file): Report error if fchown or fchmod
16129 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16131 * process.c (Fmake_network_process): Use socklen_t, not int,
16132 where POSIX says socklen_t is required in portable programs.
16133 This fixes a porting bug on hosts like 64-bit HP-UX, where
16134 socklen_t is wider than int (Bug#8277).
16135 (Fmake_network_process, server_accept_connection):
16136 (wait_reading_process_output, read_process_output):
16139 * process.c: Rename or move locals to avoid shadowing.
16140 (list_processes_1, Fmake_network_process):
16141 (read_process_output_error_handler, exec_sentinel_error_handler):
16142 Rename or move locals.
16143 (Fmake_network_process): Define label "retry_connect" only if needed.
16144 (Fnetwork_interface_info): Fix pointer signedness.
16145 (process_send_signal): Add cast to avoid pointer signedness problem.
16146 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
16147 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
16149 Make tparam.h and terminfo.c consistent.
16150 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16151 Include tparam.h instead, since it declares them.
16152 * cm.h (PC): Remove extern decl; tparam.h now does this.
16153 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16154 * terminfo.c: Include tparam.h, to check interfaces.
16155 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16156 (tparam): Adjust signature to match interface in tparam.h;
16157 this removes some undefined behavior. Check that outstring and len
16158 are zero, which they always are with Emacs.
16159 * tparam.h (PC, BC, UP): New extern decls.
16161 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
16162 (xftfont_open): Rename locals to avoid shadowing.
16164 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
16165 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
16166 (OTF_TAG_SYM): Omit macro if not needed.
16167 (ftfont_list): Remove unused local.
16168 (get_adstyle_property, ftfont_pattern_entity):
16169 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
16170 Rename locals to avoid shadowing.
16172 * xfont.c (xfont_list_family): Mark var as initialized.
16174 * xml.c (make_dom): Now static.
16176 * composite.c (composition_compute_stop_pos): Rename local to
16178 (composition_reseat_it): Remove unused locals.
16179 (find_automatic_composition, composition_adjust_point): Likewise.
16180 (composition_update_it): Mark var as initialized.
16181 (find_automatic_composition): Mark vars as initialized,
16182 with a FIXME (Bug#8290).
16184 character.h: Rename locals to avoid shadowing.
16185 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
16186 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
16187 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16188 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16189 to avoid shadowing.
16191 * textprop.c (property_change_between_p): Remove; unused.
16193 * intervals.c (interval_start_pos): Now static.
16195 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
16197 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
16198 Rename locals to avoid shadowing.
16200 * sound.c (wav_play, au_play, Fplay_sound_internal):
16201 Fix pointer signedness.
16202 (alsa_choose_format): Remove unused local var.
16203 (wav_play): Initialize a variable to 0, to prevent undefined
16204 behavior (Bug#8278).
16206 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16208 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16210 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16211 clobbering (Bug#8298).
16212 * sysdep.c (sys_subshell): Likewise.
16213 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16215 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16216 This should get cleaned up, so that child_setup has the
16217 same signature on all platforms.
16219 * callproc.c (call_process_cleanup): Now static.
16220 (relocate_fd): Rename locals to avoid shadowing.
16222 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16224 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16225 not to be necessary, and produces flickering.
16227 2011-03-20 Glenn Morris <rgm@gnu.org>
16229 * config.in: Remove file.
16231 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
16233 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
16234 are now in src/globals.h.
16235 (syms_of_minibuf): Remove spurious & from previous change.
16237 2011-03-20 Leo Liu <sdl.web@gmail.com>
16239 * minibuf.c (completing-read-function): New variable.
16240 (completing-read-default): Rename from completing-read.
16241 (completing-read): Call completing-read-function.
16243 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16245 * xfaces.c (Fx_load_color_file):
16246 Read color file from absolute filename (bug#8250).
16248 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
16250 * makefile.w32-in: Update dependencies.
16252 2011-03-17 Eli Zaretskii <eliz@gnu.org>
16254 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
16256 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>
16258 Fix more problems found by GCC 4.5.2's static checks.
16260 * process.c (make_serial_process_unwind, send_process_trap):
16261 (sigchld_handler): Now static.
16263 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16264 That way, the code declares only the vars that it needs.
16265 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
16266 * s/cygwin.h (PTY_ITERATION): Likewise.
16267 * s/darwin.h (PTY_ITERATION): Likewise.

16270 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
16271 * process.c (allocate_pty): Don't declare stb unless it's needed.
16273 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
16274 (CONSTANTLIM): Remove; unused.
16275 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
16276 Define only if needed.
16278 * unexelf.c (unexec): Name an expression,
16279 to avoid gcc -Wbad-function-cast warning.
16280 Use a different way to cause a compilation error if anyone uses
16281 n rather than nn, a way that does not involve shadowing.
16282 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16284 * deps.mk (unexalpha.o): Remove; unused.
16286 New file unexec.h, the (simple) interface for unexec (Bug#8267).
16287 * unexec.h: New file.
16288 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
16289 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
16290 Depend on unexec.h.
16291 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
16292 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
16293 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
16294 Change as necessary to match prototype in unexec.h.
16296 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
16298 (back_comment, skip_chars): Mark vars as initialized.
16300 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

16306 * print.c (Fredirect_debugging_output): Fix pointer signedess.
16308 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
16309 warning when compiling print.c.

16312 instead of using an uninitialized var.
16313 (font_sort_entities): Mark var as initialized.
16315 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
16317 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

16329 * floatfns.c (domain_error2): Define only if needed.
16330 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
16332 * alloc.c (mark_backtrace): Move decl from here ...
16333 * lisp.h: ... to here, so that it can be checked.

16336 (Fdefvar): Rewrite so as not to use empty "else".
16337 (lisp_indirect_variable): Name an expression,
16338 to avoid gcc -Wbad-function-cast warning.

16341 * callint.c (quotify_arg, quotify_args): Now static.
16342 (Fcall_interactively): Rename locals to avoid shadowing.
16343 Use const pointer when appropriate.
16345 * lisp.h (get_system_name, get_operating_system_release):

16347 * process.c (get_operating_system_release): Move decl to lisp.h.
16348 * xrdb.c (get_system_name): Likewise.
16349 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16350 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16351 some of which prompt warnings from gcc -Wbad-function-cast.
16352 (Fformat_time_string, Fencode_time, Finsert_char):
16353 (Ftranslate_region_internal, Fformat):
16354 Rename or remove local vars to avoid shadowing.
16355 (Ftranslate_region_internal): Mark var as initialized.
16357 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16360 * lisp.h (eassert): Check that the argument compiles, even if
16361 ENABLE_CHECKING is not defined.
16363 * data.c (Findirect_variable): Name an expression, to avoid
16364 gcc -Wbad-function-cast warning.
16365 (default_value, arithcompare, arith_driver, arith_error): Now static.

16372 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
16373 Rename locals to avoid shadowing.
16374 (mark_stack): Move local variables into the #ifdef region where
16376 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16377 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16379 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16380 (GC_STRING_CHARS): Remove; not used.
16381 (Fmemory_limit): Cast sbrk's returned value to char *.
16383 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16384 avoids undefined behavior in theory.
16386 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16388 Use functions, not macros, for up- and down-casing (Bug#8254).
16389 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16390 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16391 to use the following functions instead of these macros.
16392 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16393 EMACS_INT, since callers assume the returned value fits in int.
16394 (upcase1): Likewise, for UPCASE_TABLE.
16395 (uppercasep, lowercasep, upcase): New static inline functions.
16396 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
16397 the race-condition problem in the old DOWNCASE.
16399 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
16400 Rename locals to avoid shadowing.
16401 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16402 (regex_compile, re_search_2, re_match_2_internal):
16403 Remove unused local vars.
16404 (FREE_VAR): Rewrite so as not to use empty "else",
16405 which gcc can warn about.
16406 (regex_compile, re_match_2_internal): Mark locals as initialized.
16407 (RETALLOC_IF): Define only if needed.
16408 (WORDCHAR_P): Likewise. This one is never needed, but is used
16409 only in a comment talking about a compiler bug, so put inside
16410 the #if 0 of that comment.
16411 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16412 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16415 * search.c (boyer_moore): Rename locals to avoid shadowing.
16416 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16417 (PREV_CHAR_BOUNDARY): Likewise.

16427 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16429 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16430 Rename locals to avoid shadowing.
16431 (Fvertical_motion): Mark locals as initialized.
16433 * casefiddle.c (casify_object, casify_region): Now static.
16434 (casify_region): Mark local as initialized.
16436 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16438 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16439 New macros, so that the caller can use some names other than
16440 gcpro1, gcpro2, etc.
16441 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16443 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16444 argument, for consistency with GCPRO2_VAR, etc: it is now the
16445 prefix of the variable, not the variable itself. All uses
16447 * dired.c (directory_files_internal, file_name_completion):
16448 Rename locals to avoid shadowing.
16450 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16451 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16452 dired.c's scmp function, had undefined behavior.
16453 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16454 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16455 * buffer.h: ... to here, because these macros use current_buffer,
16456 and the new implementation with inline functions needs to have
16457 current_buffer in scope now, rather than later when the macros
16459 (downcase, upcase1): New static inline functions.
16460 (DOWNCASE, UPCASE1): Reimplement using these functions.
16461 This avoids undefined behavior in expressions like
16462 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16463 from race conditions in accessing the global variables
16464 case_temp1 and case_temp2.
16465 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16466 * lisp.h (case_temp1, case_temp2): Remove their decls.
16467 * character.h (ASCII_CHAR_P): Move from here ...
16468 * lisp.h: ... to here, so that the inline functions mentioned
16469 above can use them.
16471 * dired.c (directory_files_internal_unwind): Now static.
16473 * fileio.c (file_name_as_directory, directory_file_name):
16474 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16476 (file_name_as_directory): Use const pointers when appropriate.
16477 (Fexpand_file_name): Likewise. In particular, newdir might
16478 point at constant storage, so make it a const pointer.
16479 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16480 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16482 (Fset_file_times, Finsert_file_contents, auto_save_error):
16483 Rename locals to avoid shadowing.
16485 * minibuf.c (choose_minibuf_frame_1): Now static.
16486 (Ftry_completion, Fall_completions): Rename or remove locals
16487 to avoid shadowing.
16489 * marker.c (bytepos_to_charpos): Remove; unused.
16491 * lisp.h (verify_bytepos, count_markers): New decls,
16492 so that gcc does not warn that these functions aren't declared.
16494 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16495 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16496 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16497 (copy_text): Remove unused local var.
16499 * filelock.c (within_one_second): Now static.
16500 (lock_file_1): Rename local to avoid shadowing.
16502 * buffer.c (fix_overlays_before): Mark locals as initialized.
16503 (fix_start_end_in_overlays): Likewise. This function should be
16504 simplified by using pointers-to-pointers, but that's a different
16506 (switch_to_buffer_1): Now static.
16507 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16508 (report_overlay_modification): Rename locals to avoid shadowing.
16510 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
16511 Fix pointer signedness issue.
16512 (sys_subshell): Mark local as volatile if checking for lint,
16513 to suppress a gcc -Wclobbered warning that does not seem to be right.
16514 (MAXPATHLEN): Define only if needed.
16516 * process.c (serial_open, serial_configure): Move decls from here ...
16517 * systty.h: ... to here, so that they can be checked.
16519 * fns.c (get_random, seed_random): Move extern decls from here ...
16520 * lisp.h: ... to here, so that they can be checked.
16522 * sysdep.c (reset_io): Now static.
16523 (wait_for_termination_signal): Remove; unused.
16525 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
16526 (copy_keymap_item, append_key, push_text_char_description):
