1 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>
4 * sysdep.c (rename) [!HAVE_RENAME]: Remove.
7 * s/hpux10-20.h (HAVE_PERROR): Remove.
8 * sysdep.c (perror) [HPUX && !HAVE_PERROR]:
9 Remove dummy definition, as this problem was obsolete long ago.
12 * sysdep.c (strerror) [!HAVE_STRERROR && !WINDOWSNT]: Remove.
14 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
16 Avoid calls to strlen in font processing functions.
17 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)

34 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
36 Remove "#define unix" that is no longer needed (Bug#11905).
37 * s/aix4-2.h (unix): Remove; no longer needed.
39 EMACS_TIME simplification (Bug#11875).
40 This replaces macros (which typically do not work in GDB)
41 with functions, typedefs and enums, making the code easier to debug.
42 The functional style also makes code easier to read and maintain.
43 * systime.h: Include <sys/time.h> on all hosts, not just if
44 WINDOWSNT, since 'struct timeval' is needed in general.
45 (EMACS_TIME): Now a typedef, not a macro.
46 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
48 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
49 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
50 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
51 (EMACS_TIME_LE): Now functions, not macros.
52 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
53 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
54 which are not functions. All uses rewritten to use:
55 (make_emacs_time): New function.
56 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
57 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
58 not functions. All uses rewritten to use the following, respectively:
59 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
60 (add_emacs_time, sub_emacs_time): New functions.
61 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
62 * fileio.c (Fcopy_file):
63 * xterm.c (XTflash): Get the current time closer to when it's used.
64 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
66 * bytecode.c (targets): Suppress -Woverride-init warnings.
68 Simplify by avoiding confusing use of strncpy etc.
69 * doc.c (Fsnarf_documentation):
70 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
71 * frame.c (Fmake_terminal_frame):
72 * gtkutil.c (get_utf8_string):
74 * nsmenu.m (ns_update_menubar):
76 Prefer memcpy to strncpy and strncat when either will do.
77 * fileio.c (Fsubstitute_in_file_name):
78 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
79 (menu_separator_name_p):
80 * nsmenu.m (ns_update_menubar):
81 Prefer memcmp to strncmp when either will do.
82 * nsterm.m: Include <ftoastr.h>.
84 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
85 Prefer snprintf to strncpy.
86 * nsterm.m (ns_term_init):
87 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
88 * nsterm.m (ns_term_init):
89 Avoid the need for strncpy, by using build_string or
90 make_unibyte_string directly. Use dtoastr, not snprintf.
91 * process.c (Fmake_network_process): Diagnose service names that
92 are too long, rather than silently truncating them or creating
93 non-null-terminated names.
94 (Fnetwork_interface_info): Likewise, for interface names.
95 * sysdep.c (system_process_attributes) [GNU_LINUX]:
96 Prefer sprintf to strncat.
97 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
98 Prefer vsnprintf to vsprintf + strncpy.
100 2012-07-10 Glenn Morris <rgm@gnu.org>
102 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
103 Clarify fallback case.
105 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
107 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
108 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
109 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
110 * w32menu.c, window.c, xmenu.c: Changed to use XCAR and XCDR
111 where argument type is known to be a Lisp_Cons.
113 2012-07-10 Tom Tromey <tromey@redhat.com>
115 * bytecode.c (BYTE_CODE_THREADED): New macro.
116 (BYTE_CODES): New macro. Replaces all old byte-code defines.
117 (enum byte_code_op): New type.
118 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
119 (exec_byte_code): Use them. Use token threading when applicable.
121 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
123 Optimize pure C strings initialization.
124 * lisp.h (make_pure_string): Fix prototype.
125 (build_pure_c_string): New function, defined as static inline. This
126 provides a better opportunity to optimize away calls to strlen when
127 the function is called with compile-time constant argument.
128 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
129 argument, adjust users accordingly. Use build_pure_c_string where
131 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
132 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
133 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
135 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
137 Avoid calls to strlen in miscellaneous functions.
138 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
139 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
140 * lread.c (openp): Likewise.
142 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
144 Avoid calls to strlen in path processing functions.
145 * fileio.c (file_name_as_directory): Add comment. Change to add
146 srclen argument and return the length of result. Adjust users
148 (directory_file_name): Fix comment. Change to add srclen argument,
149 swap 1st and 2nd arguments to obey the common convention. Adjust
151 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
153 2012-07-10 Glenn Morris <rgm@gnu.org>
155 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
156 Move PENDING_OUTPUT_COUNT definition to configure.
158 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
159 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
160 * s/gnu.h (DATA_START): Move definitions to configure.
162 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
163 We include usg5-4-common.h, which defines them both.
165 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
166 O_RDONLY already includes it).
168 Stop ns builds setting the EMACSLOADPATH environment variable.
169 * nsterm.m (ns_load_path): Rename from ns_init_paths.
170 Now it does not set EMACSLOADPATH, just returns the load-path string.
171 * nsterm.h: Update accordingly.
172 * lread.c [HAVE_NS]: Include nsterm.h.
173 (init_lread) [HAVE_NS]: Use ns_load_path.
174 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
176 2012-07-09 Glenn Morris <rgm@gnu.org>
178 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
179 since the included bsd-common.h does so.
181 Stop ns builds setting the EMACSPATH environment variable.
182 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
183 (ns_init_paths): Do not set EMACSPATH.
184 * nsterm.h (ns_exec_path): Add it.
185 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
188 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
190 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
192 * process.c (wait_reading_process_output): 'waitchannels' was unset
193 when read_kbd || !NILP (wait_for_cell); fix this.
195 Add GCC-style 'const' attribute to functions that can use it.
196 * character.h (char_resolve_modifier_mask):
197 * keyboard.h (make_ctrl_char):
198 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
199 (init_character_once, next_almost_prime, init_fns, init_image)
200 (flush_pending_output, init_sound):
201 * mem-limits.h (start_of_data):
202 * menu.h (finish_menu_items):
204 * emacs.c (DEFINE_DUMMY_FUNCTION):
205 Declare the dummy function with ATTRIBUTE_CONST.
206 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
207 Add decls with ATTRIBUTE_CONST.
209 Minor improvements to make_formatted_string.
210 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
211 where int is good enough, as vsprintf returns an int.
212 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
214 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
216 Use make_formatted_string to avoid double length calculation.
217 * lisp.h (make_formatted_string): New prototype.
218 * alloc.c (make_formatted_string): New function.
219 * buffer.c (Fgenerate_new_buffer_name): Use it.
220 * dbus.c (syms_of_dbusbind): Likewise.
221 * editfns.c (Fcurrent_time_zone): Likewise.
222 * filelock.c (get_boot_time): Likewise.

241 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
243 Move marker debugging code under MARKER_DEBUG.
244 * marker.c (MARKER_DEBUG): Move marker debugging code under
245 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
246 for bootstrap with --enable-checking (~3x slowdown reported
247 by Juanma Barranquero <lekktu@gmail.com>).
248 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
250 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
252 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
253 See <http://bugs.gnu.org/11825#29>.
255 2012-07-08 Eli Zaretskii <eliz@gnu.org>
257 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
258 has no font, use the frame's font. (Bug#11813)
259 (display_line): Add commentary about displaying truncation glyphs
261 (produce_special_glyphs): Move here from term.c.
263 * term.c (produce_special_glyphs): Move to xdisp.c.
265 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
268 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
270 * xdisp.c (display_line): Avoid warning about implicit declaration
273 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
275 * lisp.h: Remove empty conditional.
277 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
279 * lread.c (load_path_check): Now static.
281 Fix some minor --with-ns problems found by static checking.
282 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
283 (x_set_font) [!HAVE_X_WINDOWS]:
284 * image.c (xpm_load_image) [HAVE_NS]:
285 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
286 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
288 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
289 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
290 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
291 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
292 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
293 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
294 Fix pointer signedness problem.
295 * xfaces.c (FRAME_X_FONT_TABLE):
296 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
298 2012-07-07 Glenn Morris <rgm@gnu.org>
300 * lread.c (load_path_check): New function, split from init_lread.
301 (init_lread): Reorganize. Motivation:
302 If EMACSLOADPATH is set, check/warn about that rather than the
303 defaults, which we are not going to use. Hence we can remove
304 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
305 Don't warn if site-lisp directories are missing.
306 If not installed, start from a blank load-path, since
307 PATH_LOADSEARCH refers to the eventual installation directories.
309 2012-07-07 Eli Zaretskii <eliz@gnu.org>
311 Support truncation and continuation glyphs on GUI frames, when
312 fringes are disabled. (Bug#11832)
313 * xdisp.c (init_iterator): Get dimensions of truncation and
314 continuation glyphs even if on GUI frames. Adjust
315 it->last_visible_x on GUI frames when the left or right fringes,
317 (start_display, move_it_in_display_line_to): Handle the case of a
318 GUI frame without a fringe to display continuation or truncation
320 (insert_left_trunc_glyphs): Support GUI frames: make sure
321 truncation glyphs overwrite enough glyphs from the current line to
322 have sufficient space in pixels.
323 (display_line): Support truncation and continuation glyphs on GUI
324 frames. If some spare pixels are left on the line after inserting
325 the truncation glyphs, fill that space with a stretch glyph of a
326 suitably computed width.
328 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
329 produce_glyphs, to support GUI sessions.
331 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
333 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
335 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
337 Do not require float-time's arg to fit in time_t (Bug#11825).
338 This works better on hosts where time_t is unsigned, and where
339 float-time is applied to the (negative) difference between two times.
340 * editfns.c (decode_time_components): Last arg is now double *,
341 not int *, and means to store all the result as a double, without
342 worrying about whether the seconds part fits in time_t.
344 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
346 (Ffloat_time): Do not fail merely because the specified time falls
347 outside of time_t range.
349 2012-07-07 Glenn Morris <rgm@gnu.org>
351 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

355 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
357 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
360 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
362 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
364 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
365 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
366 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
367 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
368 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
369 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
371 * xfont.c (compare_font_names): Redo to omit the need for casts.
373 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
375 * xfns.c (Fx_change_window_property): Doc fix.
376 * w32fns.c (Fx_change_window_property): Doc fix.
378 * w32fns.c (Fx_window_property): Accept the same arguments as the
379 X Windows version. Doc fix.
380 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
382 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
383 Eli Zaretskii <eliz@gnu.org>
385 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
386 Windows-specific code from nt/config.nt moved here.
387 Obsolete settings removed.
389 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
391 * process.c: Avoid unnecessary calls to gettime.
392 (wait_reading_process_output): Don't get the time of day
393 when gobbling data immediately and not waiting, as there's no need
394 for it in that case. This removes a FIXME.
396 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
398 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
399 is defined (Bug#11768).
401 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
403 Fix marker debugging code.
404 * marker.c (byte_char_debug_check): Do not perform the check
405 if buffer is not multibyte.
406 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
407 Call byte_char_debug_check with correct arguments.
409 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
411 Compile marker debugging code only if ENABLE_CHECKING is defined.
412 * marker.c (byte_char_debug_check, count_markers):
413 Use only if ENABLE_CHECKING is defined.
414 (byte_debug_flag): Remove.
415 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
416 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
418 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
420 Avoid code repetition in marker-related functions.
421 * marker.c (attach_marker): New function.
422 (Fset_marker, set_marker_restricted, set_marker_both)
423 (set_marker_restricted_both): Use it.
424 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
425 Consistently rename charno to charpos.
426 (marker_position): Add eassert.
427 (marker_byte_position): Convert to eassert.
429 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
431 Simplify list operations in unchain_overlay and unchain_marker.
432 * buffer.c (unchain_overlay): Simplify. Add comment.
433 * marker.c (unchain_marker): Simplify. Fix comments.
435 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

446 * window.c (save_window_save): Likewise.
448 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
450 Do not use Fdelete_overlay in delete_all_overlays
451 to avoid redundant calls to unchain_overlay.
452 * buffer.c (drop_overlay): New function.
453 (delete_all_overlays, Fdelete_overlay): Use it.
454 * minibuf.c (get_minibuffer): Fix comment.
456 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
458 Port to OpenBSD 5.1 amd64.
459 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
460 This is needed for OpenBSD, and should be harmless on all BSD systems.
461 Also, include <sys/sysctl.h>, as it should be available on all
462 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
463 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
464 use p_pid member, not kp_proc.pid.
466 2012-07-06 Glenn Morris <rgm@gnu.org>
468 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
470 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
472 More xmalloc and related cleanup.
473 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

481 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
483 Omit needless casts involving void * pointers and allocation.
484 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
485 as the former is more robust if P's type is changed.
486 Prefer xzalloc to xmalloc + memset 0.
487 Simplify malloc-or-realloc to realloc.
488 Don't worry about xmalloc returning a null pointer.

490 * editfns.c (Fmessage_box): Grow message_text by at least 80 when

493 alloca of a constant.
495 2012-07-05 Eli Zaretskii <eliz@gnu.org>
497 * xdisp.c (display_line): Fix horizontal pixel coordinates when
498 hscroll is larger than the line width. Fixes long and futile
499 looping inside extend_face_to_end_of_line (on a TTY) producing
500 glyphs that are not needed and thrown away.

519 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
520 (update_theme_scrollbar_width, xg_create_scroll_bar):
521 Use gtk_scrollbar_new (Bug#11768).
522 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
523 (is_box_type): New function (Bug#11768).
524 (xg_tool_item_stale_p): Call is_box_type.
525 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
526 with default display (Bug#11768).

535 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
537 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

602 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
604 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
605 This should be fixed in a better way; see Eli Zaretskii in
606 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
607 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
609 * fileio.c (time_error_value): Rename from special_mtime.
610 The old name's problems were noted by Eli Zaretskii in
611 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
613 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
614 This variable's comment says Emacs needs at least one GDB-visible
615 symbol of type enum pvec_type, to work around GDB problems.
616 The symbol's value doesn't matter.
618 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
619 that causes compilation to fail on pre-C99 compilers.
621 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
623 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

629 headers for buffer_defaults and buffer_local_symbols.
630 Reported by Juanma Barranquero <lekktu@gmail.com>.
632 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
634 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
635 * lisp.h (enum pvec_type): Use fewer bits.

646 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
647 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
648 (sweep_vectors): Use it. Use local var `total_bytes' instead of
649 abusing vector->header.next.nbytes.
650 (live_vector_p): Use PVEC_TYPE.
651 (mark_object): Adapt code to extract pvectype. Use switch.
653 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>

663 to avoid compiler warning. Add eassert.
664 * search.c (simple_search): Initialize match_byte to avoid
665 compiler warning. Add eassert.
667 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
669 Avoid weird behavior with large horizontal scrolls.
670 Without this change, for example, large hscroll values would
671 mess up Emacs's display on Fedora 15 x86, presumably due to
672 overflows in int calculations in the display code.
673 Also, if buffers had long lines, Emacs would freeze.
674 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
675 (set_window_hscroll): New function, containing the old guts of
676 Fset_window_hscroll. Return the clipped value.
677 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
678 This avoids the need to check against PTRDIFF_MAX.
680 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
682 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
684 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
686 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
688 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
689 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
690 since GCC 4.4.6 issues a bogus warning for them.
692 Fix bugs in file timestamp newness comparisons.
693 * fileio.c (Ffile_newer_than_file_p):
694 * lread.c (Fload): Use full timestamp resolution of files,
695 not just the 1-second resolution, so that files that are only
696 slightly newer still count as newer.
697 * fileio.c (Ffile_newer_than_file_p): Don't assume file
698 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
700 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
702 * fileio.c: Improve handling of file time marker. (Bug#11852)
703 (special_mtime): New function.
704 (Finsert_file_contents, Fverify_visited_file_modtime):
705 Use it to set special mtime values consistently.
707 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
709 * fileio.c (Finsert_file_contents): Properly handle st_mtime
710 marker for non-existing file. (Bug#11852)
712 2012-07-03 Glenn Morris <rgm@gnu.org>
714 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
715 and did not make it into globals.h).

759 buffer for invisible buffers. (Bug#1229)
761 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
763 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
764 values which aren't power of 2.
765 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
766 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
769 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
771 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
773 * alloc.c (mark_object): Revert part of last patch to use `switch'.
775 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
777 * alloc.c (allocate_vector_block): Remove redundant
778 calls to mallopt if DOUG_LEA_MALLOC is defined.
779 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
780 avoid calls to mallopt if zero_vector is returned.
782 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
784 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
785 is enabled, avoid dereferencing NULL current_sblock if
788 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
790 Cleanup basic buffer management.
791 * buffer.h (struct buffer): Change layout to use generic vector
792 marking code. Fix some comments. Change type of 'clip_changed'
793 to bitfield. Remove unused #ifndef old.
794 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
795 (GET_OVERLAYS_AT): Fix indentation.
796 (for_each_per_buffer_object_at): New macro.

800 * alloc.c (allocate_buffer): Adjust to match new layout of
801 struct buffer. Fix comment.

804 Lisp area of struct buffer.
805 (mark_object): Use it. Adjust marking of misc objects
806 and related comments.
808 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
810 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
811 wrapper that is not needed because the wrapped code is a no-op (zero
812 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
813 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
815 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
817 * alloc.c (mark_buffer): Simplify. Remove prototype.
818 (mark_object): Add comment. Reorganize marking of vector-like
819 objects. Use CHECK_LIVE for all vector-like objects except buffers
820 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
821 redundant calls to mark_vectorlike for bool vectors.
823 2012-06-30 Glenn Morris <rgm@gnu.org>
825 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
827 * epaths.in (PATH_SITELOADSEARCH): New.
828 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
829 This is rather than relying on --enable-locallisppath elements
830 having "site-lisp" in their names. (Bug#10208#25, 11658)
832 2012-06-30 Eli Zaretskii <eliz@gnu.org>
834 * w32proc.c (sys_select): Accept and ignore one more argument.
836 * w32.c (emacs_gnutls_pull): Call select with one more argument.
838 * sysselect.h [DOS_NT]: Don't include sys/select.h.
839 (pselect) [!MS_DOS]: Redirect to sys_select.
841 * sysdep.c: Don't include dos.h and dosfns.h.
843 * process.c (sys_select):
844 * msdos.c (sys_select): Accept one more argument and ignore it.
846 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
847 adapt data types and code to that.
850 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
851 which clashes with the gnulib function of the same name.
853 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
855 * font.c (font_style_to_value, font_style_symbolic)

864 2012-06-29 Eli Zaretskii <eliz@gnu.org>
866 * xdisp.c (try_window_id): Undo last change.
868 * w32.c (getwd): Adjust commentary about startup_dir.
869 (init_environment): Always call sys_access, even in non-MSVC
870 builds. Don't chdir to the directory of the Emacs executable.
871 This undoes code from 1997 which was justified by the need to
872 "avoid conflicts when removing and renaming directories". But its
873 downside was that every relative file name was being interpreted
874 relative to the directory of the Emacs executable, which can never
875 be TRT. In particular, it broke sys_access when called with
877 (sys_access): Map GetLastError to errno.
879 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
881 * window.h (struct window): Change type of 'fringes_outside_margins'
882 to bitfield. Fix comment. Adjust users accordingly.
883 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
885 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
888 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

891 Add QUIT to make the loop interruptible.
893 2012-06-29 Glenn Morris <rgm@gnu.org>
895 * charset.c (init_charset): Make lack of etc/charsets fatal.
897 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
899 * editfns.c (region_limit): Fix type mismatch.
901 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
903 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
904 undefined. Convert from xassert to eassert.
905 * nsmenu.m: Convert from xassert to eassert.
906 * nsterm.m: Likewise.
908 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

914 Avoid integer overflow on scroll-left and scroll-right.
915 * window.c (HSCROLL_MAX): New macro.
916 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
917 overflow when requested scroll falls outside ptrdiff_t range.
919 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
921 * window.h (struct window): Change type of 'hscroll',
922 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
923 'last_modified' and 'last_overlay_modified' to EMACS_INT.
924 Adjust users accordingly.
925 * xdisp.c (try_cursor_movement): Replace type check with eassert.
926 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
927 from EMACS_INT to ptrdiff_t.
928 (make_window): Omit redundant initialization.
930 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
932 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
934 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
936 * window.h (struct window): Change type of 'use_time' and
937 'sequence_number' from Lisp_Object to int.
938 * frame.c (make_frame): Adjust users accordingly.
939 * print.c (print_object): Likewise.
940 * window.c (select_window, Fwindow_use_time, make_parent_window)
941 (make_window): Likewise.
943 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
945 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
946 enabled with --enable-checking=[all,glyphs] configure option.
947 Fix GLYPH_DEBUG usage assuming that it may be undefined,
948 adjust comments accordingly.

1069 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1071 Use sprintf return value instead of invoking strlen on result.
1072 In the old days this wasn't portable, since some sprintf
1073 implementations returned char *. But they died out years ago and
1074 Emacs already assumes sprintf returns int.
1075 Similarly for float_to_string.
1076 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
1077 * ccl.c (ccl_driver):
1078 * character.c (string_escape_byte8):

1081 * print.c (print_object):
1082 * xdisp.c (message_dolog):
1083 * xfns.c (syms_of_xfns):
1084 Use sprintf or float_to_string result to avoid need to call strlen.
1085 * data.c (Fnumber_to_string):
1086 Use make_unibyte_string, since the string must be ASCII.
1087 * lisp.h, print.c (float_to_string): Now returns int length.
1088 * term.c (produce_glyphless_glyph):
1089 Use sprintf result rather than recomputing it.
1091 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1092 * Makefile.in (ALL_CFLAGS):
1093 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
1094 * gmalloc.c, regex.c: Include <config.h> unconditionally.

1098 * dispextern.h (xstrcasecmp): Define to library function
1099 strcasecmp if available.
1100 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
1102 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

1115 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
1117 * gtkutil.c (get_utf8_string): Remove redundant assignment.
1118 sprintf already null-terminates its output.
1120 * xfns.c (x_window): Remove redundant cast.
1122 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1124 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
1125 `const char *' to `char *' to avoid compiler warning.
1127 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1129 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1130 instead of truncating it to 63 (admittedly a generous limit).
1132 * process.c: Fix spelling and caps in comments.
1134 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
1136 * emacs.c (setpgrp): Remove definition, unused.

1183 Remove unnecessary forward decls.
1185 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1187 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
1188 * lisp.h (WAIT_READING_MAX): New macro.
1189 * dispnew.c (Fsleep_for, sit_for):
1190 * keyboard.c (kbd_buffer_get_event):
1191 * process.c (Faccept_process_output):
1192 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1193 This improves on the previous patch, which introduced a bug
1194 when time_t is unsigned and as wide as intmax_t.
1195 See <http://bugs.gnu.org/9000#51>.
1197 2012-06-23 Eli Zaretskii <eliz@gnu.org>

1213 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
1214 Privately reported by Herbert J. Skuhra.
1215 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
1217 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
1218 not make_lisp_timeval, when the argument is of type EMACS_TIME.
1220 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1222 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
1223 last argument of make_unibyte_string.
1225 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
1226 language ID in the event parameters.
1228 * w32term.c (w32_read_socket): Put the new keyboard codepage into
1229 event.code, not the obscure "character set ID".
1231 2012-06-23 Chong Yidong <cyd@gnu.org>
1233 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
1235 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1237 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

1252 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
1253 Privately reported by Herbert J. Skuhra.

1258 Don't assume EMACS_TIME and struct timeval are the same type.
1260 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1262 Support higher-resolution time stamps (Bug#9000).
1263 The time stamps are only nanosecond-resolution at the C level,
1264 since that's the best that any real-world system supports now.
1265 But they are picosecond-resolution at the Lisp level, as that's
1266 easy, and leaves room for future OS improvements.
1268 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1271 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1272 Don't get current time unless it's needed.
1274 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1275 now provides it if it's absent.
1276 (start_atimer): Port to higher-res time stamps.
1277 Check for time stamp overflow. Don't get current time more
1278 often than is needed.
1280 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1281 Include systime.h, not time.h.
1282 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1284 * dired.c: Include stat-time.h.
1285 (Ffile-attributes): File times now have higher resolution.

1288 (struct image): Timestamp now has higher resolution.
1290 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1291 has at least microseconds now. All uses removed.
1292 (update_frame, update_single_window, update_window, update_frame_1)
1293 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1295 * editfns.c (time_overflow): Now extern.
1296 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1297 (float-time, Fformat_time_string, Fcurrent_time_string)
1298 (Fcurrent_time_zone): Accept and generate higher-resolution
1300 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
1301 (decode_time_components, lisp_seconds_argument): New functions.
1302 (make_time): Now static.
1303 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1304 Report an error if the time is invalid, rather than having the caller
1307 * fileio.c: Include <stat-time.h>
1308 (Fcopy_file): Copy higher-resolution time stamps.
1309 Prefer to set the time stamp via a file descriptor if that works.
1310 (Fset_file_times, Finsert_file_contents, Fwrite_region)
1311 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1312 (Fvisited_file_modtime, Fset_visited_file_modtime):
1313 Support higher-resolution time stamps.
1315 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1317 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1319 * image.c (prepare_image_for_display, clear_image_cache)
1320 (lookup_image): Port to higer-resolution time stamps.
1322 * keyboard.c (start_polling, bind_polling_period):
1323 Check for time stamp overflow.
1324 (read_char, kbd_buffer_get_event, timer_start_idle)
1325 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1326 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1327 Port to higher-resolution time stamps. Do not assume time_t is signed.
1328 (decode_timer): New function. Timers are now vectors of length 9,
1329 not 8, to accommodate the picosecond component.
1330 (timer_check_2): Use it.
1332 * nsterm.m (select_timeout, timeval_subtract): Remove.
1333 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1334 as they're a bit more accurate and handle overflow better.
1335 (ns_select): Change prototype to be compatible with pselect.
1336 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1337 * nsterm.h (ns_select): Adjust prototype.
1339 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1340 us-resolution time stamps.
1341 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1343 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1345 * lisp.h (time_overflow): New decl.
1346 (wait_reading_process_output): First arg is now intmax_t, not int,
1347 to accommodate larger waits.
1349 * process.h (struct Lisp_Process.read_output_delay):
1350 Now counts nanoseconds, not microseconds.
1351 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1353 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1354 (wait_reading_process_output):
1355 Port to ns-resolution time stamps.
1356 (Faccept_process_output, wait_reading_process_output):
1357 Check for time stamp overflow. Do not assume time_t is signed.
1358 (select_wrapper): Remove; we now use pselect.
1359 (Fprocess_attributes): Now generates ns-resolution time stamps.
1361 * sysdep.c: Include utimens.h. Don't include utime.h
1362 or worry about struct utimbuf; gnulib does that for us now.
1363 (gettimeofday): Remove; gnulib provides a substitute.
1364 (make_timeval): New function.
1365 (set_file_times): Now sets ns-resolution time stamps.
1366 New arg FD; all uses changed.
1367 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1368 (system_process_attributes):
1369 Now returns ns-resolution time stamp. All uses changed.
1370 Check for time stamp overflow.
1372 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1373 provides a substitute now.
1375 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1376 since it guarantees struct timespec.
1377 (EMACS_TIME): Now struct timespec, so that we can support
1378 ns-resolution time stamps.
1379 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1380 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1381 (EMACS_USECS): Remove.
1382 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1383 so multiply the arg by 1000 before storing it.
1384 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1386 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
1387 Port to ns-resolution time stamps.
1388 (EMACS_TIME_NEG_P): Remove; replaced by....
1389 (EMACS_TIME_SIGN): New macro.
1390 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
1391 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
1392 (set_file_times, make_time, lisp_time_argument): Adjust signature.
1393 (make_timeval, make_lisp_time, decode_time_components): New decls.
1394 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1395 that it mishandled time_t overflow. You can't compare by subtracting!
1396 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1397 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1399 * term.c: Include <sys/time.h>.
1400 (timeval_to_Time): New function, for proper overflow wraparound.
1401 (term_mouse_position, term_mouse_click): Use it.

1405 (Fprimitive_undo): Use them when restoring time stamps.
1407 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1408 (w32_get_internal_run_time):
1409 Port to higher-resolution Emacs time stamps.
1410 (ltime): Now accepts single 64-bit integer, as that's more convenient
1413 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1415 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1416 for compatibility with pselect. Support ns-resolution time stamps.
1418 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1420 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1421 Check for time stamp overflow, and support ns-resolution time stamps.
1423 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1424 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1425 (timeval_subtract): Remove; no longer needed.
1426 (XTflash, XTring_bell, x_wait_for_event):
1427 Port to ns-resolution time stamps. Don't assume time_t is signed.
1429 2012-06-22 Chong Yidong <cyd@gnu.org>
1431 * xdisp.c (x_consider_frame_title): Revert last change.
1433 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1435 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1436 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1437 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1438 staticidx goes up to 1597 out of 1600 = 0x640.)
1440 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1442 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1443 Otherwise, the umask might be mistakenly 0 while handling input signals.
1445 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
1447 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
1449 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
1451 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
1452 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
1453 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
1454 access to `contents' member of Lisp_Vector objects with AREF and ASET
1457 2012-06-19 Chong Yidong <cyd@gnu.org>
1459 * frame.c (delete_frame): When selecting a frame on a different
1460 text terminal, do not alter the terminal's top-frame.

1463 frame's selected window and its terminal's top-frame.
1464 (unwind_format_mode_line): Restore them.
1465 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
1467 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1468 since tty frames can be explicitly named.

1710 code works fine either way, and efficiency is not a concern here,
1711 as the union type is for debugging, not for production.
1712 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
1713 Use an inline function on all platforms when using the union type,
1714 since this is simpler and 'static inline' can be used portably

1858 * doprnt.c (doprnt): Truncate multibyte char correctly.
1859 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
1860 would mishandle a string argument "Xc" if X was a multibyte

1936 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
1937 fields from Lisp_Object to bitfield. Adjust users accordingly.

1949 * xdisp.c (handle_stop): Detect whether we have overlay strings
1950 loaded by testing it->current.overlay_string_index to be
1951 non-negative, instead of checking whether n_overlay_strings is
1952 positive. (Bug#11587)
1954 2012-05-31 Chong Yidong <cyd@gnu.org>
1956 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
1958 * doc.c (Fsubstitute_command_keys): Doc fix.
1960 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1962 * search.c (search_buffer): Remove calls to
1963 r_alloc_inhibit_buffer_relocation, as it is now called by
1964 maybe_unify_char, which was the cause of relocation of buffer text
1967 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1969 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
1970 for the duration of call to load_charset, to avoid problems with
1971 callers of maybe_unify_char that access buffer text through C
1974 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
1975 decrement the inhibition flag, instead of just setting or
1978 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
1980 Remove obsolete '#define static' cruft.
1981 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
1982 This #undef was "temporary" in 2000; it is no longer needed
1983 now that '#define static' has gone away.
1984 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
1985 (gray_bitmap_bits): Remove; no longer needed.
1986 All uses replaced with definiens.
1987 * xterm.c: Include "bitmaps/gray.xbm".
1989 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
1991 Clean up __executable_start, monstartup when --enable-profiling.
1992 The following changes affect the code only when profiling.
1993 * dispnew.c (__executable_start): Rename from safe_bcopy.
1994 Define only on platforms that need it.
1995 * emacs.c: Include <sys/gmon.h> when profiling.
1996 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
1997 (__executable_start): Remove decl, since lisp.h does it now.
1998 (safe_bcopy): Remove decl; no longer has that name.
1999 (main): Coalesce #if into single bit of code, for simplicity.
2000 Cast pointers to uintptr_t, since standard libraries want integers
2002 * lisp.h (__executable_start): New decl.
2004 2012-05-31 Glenn Morris <rgm@gnu.org>
2006 * image.c (Fimagemagick_types): Doc fix.
2008 2012-05-30 Jim Meyering <meyering@redhat.com>
2010 * callproc.c (Fcall_process_region): Include directory component

2024 * lisp.h (Qdefun): Remove.
2025 * lread.c (read1): Tiny simplification.
2027 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2029 Do not create empty overlays with the evaporate property (Bug#9642).
2030 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2031 Bug#9642, but explicitly check that the buffer the overlay would
2032 be moved to is live and rearrange lines to make sure that errors
2033 will not put the overlay in an inconsistent state.
2034 (Fdelete_overlay): Cosmetics.
2036 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2038 * w32term.c (my_bring_window_to_top): New function.
2039 (x_raise_frame): Use handle returned by DeferWindowPos, which
2040 could be different from the original one.

2044 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2045 by calling BringWindowToTop.
2047 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
2048 (WM_EMACS_END): Increase by one.
2050 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2052 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2053 This avoids undefined behavior that might cause the eassert
2054 to not catch an out-of-range value.
2056 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2058 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
2059 Update dependencies.
2061 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2063 * bidi.c (bidi_mirror_char): Fix last change.
2065 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
2067 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
2068 when referring to sectname field in printf format.
2070 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2072 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2073 Only r_alloc_inhibit_buffer_relocation needed to be added;
2074 the others were already declared.
2076 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2077 before checking whether it's out of range. Put the check inside
2079 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2081 2012-05-27 Ken Brown <kbrown@cornell.edu>
2083 * callproc.c (Fcall_process): Restore a line that was accidentally
2084 commented out in the 2011-02-13 change (bug#11547).
2086 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2088 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2089 defined on ralloc.c.
2091 * buffer.c [REL_ALLOC]: Remove prototypes of
2092 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2093 they are now on lisp.h.
2095 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2097 * search.c (search_buffer): Use it to inhibit relocation of buffer
2098 text while re_search_2 is doing its job, because re_search_2 is
2099 passed C pointers to buffer text. (Bug#11519)
2101 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2104 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2105 state after an additional call to move_it_in_display_line_to, keep
2106 the values of it->max_ascent and it->max_descent found for the
2108 (pos_visible_p): Revert the comparison against bottom_y to what it
2109 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2112 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2114 Fix coding-related core dumps with gcc -ftrapv.
2115 The code was computing A - B, where A and B are pointers, and B is
2116 random garbage. This can lead to core dumps on platforms that
2117 have special pointer registers, and it also leads to core dumps on
2118 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2119 A - B only when B is initialized properly.
2120 * coding.c (coding_set_source, coding_set_destination): Return void.
2121 (coding_change_source, coding_change_destinations): New functions,
2122 with the old behaviors of coding_set_source and coding_set_destination.
2123 All callers that need an offset changed to use these new functions.
2125 2012-05-26 Glenn Morris <rgm@gnu.org>
2127 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2129 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2131 Extend mouse support on W32 text-mode console.
2132 * xdisp.c (draw_row_with_mouse_face):
2133 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2135 * w32console.c: Include window.h.
2136 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2138 (initialize_w32_display): Initialize mouse-highlight data.
2140 * w32inevt.c: Include termchar.h and window.h.
2141 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2142 moves, call note_mouse_highlight. If help_echo changed, call
2143 gen_help_event to produce help-echo message in the echo area.
2144 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2147 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2149 * lread.c (read1): Simplify slightly to avoid an overflow warning
2150 with GCC 4.7.0 on x86-64.
2152 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2154 * bidi.c (bidi_mirror_char): Revert last change: an int is
2155 definitely wide enough here.
2157 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2159 Fix integer width and related bugs (Bug#9874).
2160 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
2161 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)

2166 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
2167 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2169 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2170 (allocate_pseudovector):
2171 Use int, not EMACS_INT, where int is wide enough.
2172 (inhibit_garbage_collection, Fgarbage_collect):
2173 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2174 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2175 int might not be wide enough.
2176 (bidi_cache_search, bidi_cache_find, bidi_init_it)
2177 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2178 (bidi_at_paragraph_end, bidi_find_paragraph_start)
2179 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2180 (bidi_level_of_next_char, bidi_move_to_visually_next):
2181 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2182 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
2183 (Fkill_buffer, Fset_buffer_major_mode)

2187 (overlay_strings, recenter_overlay_lists)
2188 (adjust_overlays_for_insert, adjust_overlays_for_delete)
2189 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
2190 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
2191 (Foverlay_recenter, last_overlay_modification_hooks_used)
2192 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2193 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2194 (validate_region): Omit unnecessary test for b <= e,
2195 since that's guaranteed by the previous test.
2196 (adjust_overlays_for_delete): Avoid pos + length overflow.
2197 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2198 (report_overlay_modification):
2199 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2200 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2201 Omit pointer cast, which isn't needed anyway, and doesn't work
2202 after the EMACS_INT -> ptrdiff_t change.
2203 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2204 * buffer.h: Adjust decls to match defn changes elsewhere.
2205 (struct buffer_text, struct buffer):

2207 Use EMACS_INT, not int, where int might not be wide enough.
2208 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
2209 not int, to avoid needless 32-bit limit on 64-bit hosts.
2210 (exec_byte_code): Use tighter memory-full test, one that checks
2211 for alloca overflow. Don't compute the address of the object just
2212 before an array, as that's not portable. Use EMACS_INT, not
2213 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2214 * callint.c (Fcall_interactively):
2215 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2216 * callproc.c (call_process_kill, Fcall_process):
2217 Don't assume pid_t fits into an Emacs fixnum.

2220 (call_process_cleanup, Fcall_process, delete_temp_file)
2221 (Fcall_process_region):
2222 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2223 (Fcall_process): Simplify handling of volatile integers.

2225 * casefiddle.c (casify_object, casify_region, operate_on_word)
2226 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2227 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2228 (casify_object): Avoid integer overflow when overallocating buffer.
2229 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2230 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
2231 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
2232 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2233 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2234 integers are now checked earlier. All uses replaced with XINT.
2236 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2237 For CCL_MapSingle, check that content and value are in int range.
2238 (ccl_driver, Fregister_code_conversion_map):
2239 Check that Vcode_version_map_vector is a vector.
2240 (resolve_symbol_ccl_program): Check that vector header is in range.
2241 Always copy the vector, so that we can check its contents reliably
2242 now rather than having to recheck each instruction as it's being
2243 executed. Check that vector words fit in 'int'.
2244 (ccl_get_compiled_code, Fregister_ccl_program)
2245 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2246 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
2247 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
2248 contents are in range.
2249 (Fccl_execute_on_string): Check that status is in range.
2250 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2251 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2252 Accept and return EMACS_INT, not int, because callers can pass values
2254 (c_string_width, strwidth, lisp_string_width, chars_in_text)

2256 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
2257 (str_as_unibyte, str_to_unibyte, string_count_byte8)
2258 (string_escape_byte8, Fget_byte):
2259 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2260 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2261 avoid mishandling large integers.
2262 * character.h: Adjust decls to match defn changes elsewhere.
2263 * charset.c (load_charset_map_from_file, find_charsets_in_text)

2271 (Fdefine_charset_internal): Check ranges here, more carefully.
2272 Don't rely on undefined behavior with signed left shift overflow.
2273 Don't assume unsigned int fits into fixnum, or that fixnum fits
2274 into unsigned int. Don't require max_code to be a valid fixnum;
2275 that's not true for gb10830 4-byte on a 32-bit host. Allow
2276 invalid_code to be a cons, for the same reason. Require code_offset
2277 to be a character. Avoid int overflow if max_char is close
2279 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2280 this is intended anyway and avoids some undefined behavior.
2281 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2282 INDEX_TO_CODE_POINT, as that's what it expects.
2283 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2284 * charset.h (DECODE_CHAR): Return int, not unsigned;
2285 this is what was intended anyway, and it avoids undefined behavior.
2286 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2287 integer-overflow issues.
2288 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2289 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2290 where the argument is EMACS_INT, and this behavior is not intended.
2291 * chartab.c (Fmake_char_table, Fset_char_table_range)
2292 (uniprop_get_decoder, uniprop_get_encoder):
2293 Don't assume fixnum fits in int.
2294 * cmds.c (move_point): New function, that does the gist of
2295 Fforward_char and Fbackward_char, but does so while checking
2296 for integer overflow more accurately.
2297 (Fforward_char, Fbackward_char): Use it.
2298 (Fforward_line, Fend_of_line, internal_self_insert)
2299 (internal_self_insert):
2300 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2301 Fix a FIXME, by checking for integer overflow when calculating
2302 target_clm and actual_clm.

2332 (Funencodable_char_position, Fcheck_coding_systems_region)
2333 (get_translation, handle_composition_annotation, consume_chars):
2334 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2335 (consume_chars): Rewrite to not calculate an address outside buffer.
2336 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
2337 Don't access memory outside of the args array.
2338 (Fdefine_coding_system_internal): Check for charset-id overflow.
2339 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
2340 result of ENCODE_CHAR.
2341 * coding.h: Adjust decls to match defn changes elsewhere.
2342 (struct coding_system):
2343 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3086 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3088 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3090 * unexaix.c: Port to more-recent AIX compilers.
3091 (report_error, report_error_1, make_hdr, copy_sym)
3092 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3093 Make arguments const char *, not char *, to avoid violations of C
3094 standard and to fix some AIX warnings reported by Gilles Pion.
3096 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3098 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3099 already have overlays loaded.
3100 (handle_single_display_spec): Before returning without displaying
3101 fringe bitmap, synchronize the bidi iterator with the main display
3102 iterator, by calling iterate_out_of_display_property.
3103 (iterate_out_of_display_property): Detect buffer iteration by
3104 testing that it->string is a Lisp string.
3105 (get_next_display_element): When the current object is exhausted,
3106 and there's something on it->stack, call set_iterator_to_next to
3107 proceed with what's on the stack, instead of returning zero.
3108 (set_iterator_to_next): If called at the end of a Lisp string,
3109 proceed to consider_string_end without incrementing string
3110 position. Don't increment display vector index past the end of
3111 the display vector. (Bug#11417)
3112 (pos_visible_p): Don't report a position visible when move_it_to
3113 stopped at the last line of window, which happens to be scanned
3114 backwards by the bidi iteration. (Bug#11464)
3116 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3118 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3119 and right-margin display specs even if the spec is invalid or we
3120 are on a TTY, and thus unable to display on the fringes.
3121 That's because the text with the property will not be displayed anyway,
3122 so we need to signal to the caller that this is a "replacing"
3123 display spec. This fixes display when the spec is invalid or we
3126 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3128 * unexaix.c (make_hdr): Fix typo in prototype.
3129 This bug broke the build on AIX. Problem reported by Gilles Pion.
3131 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3133 * keyboard.c (kbd_buffer_get_event): Read special events also in
3134 batch mode. (Bug#11415)
3136 2012-05-12 Glenn Morris <rgm@gnu.org>
3138 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3140 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3142 * lisp.mk (lisp): Add newcomment.elc.
3144 2012-05-12 Glenn Morris <rgm@gnu.org>
3146 * Makefile.in (MKDIR_P): New, set by configure.
3147 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3149 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3151 Remove unused function hourglass_started.
3152 * dispextern.h (hourglass_started):
3153 * w32fns.c (hourglass_started):
3154 * xdisp.c (hourglass_started): Remove.
3156 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3158 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3159 Update dependencies.
3161 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3163 * xgselect.c (xg_select): Put maxfds+1 into a var.
3164 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3166 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3168 2012-05-10 Dave Abrahams <dave@boostpro.com>
3170 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3171 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3173 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3175 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3176 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3177 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3178 Initialize xd_registered_buses.
3180 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3182 Untag more efficiently if USE_LSB_TAG.
3183 This is based on a proposal by YAMAMOTO Mitsuharu in
3184 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3185 For an admittedly artificial (nth 8000 longlist) benchmark on
3186 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3187 Emacs's overall text size by 1%.
3188 * lisp.h (XUNTAG): New macro.
3189 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3190 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3191 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3192 * eval.c (Fautoload):
3193 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3194 * frame.h (XFRAME): Use XUNTAG.
3196 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3197 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3198 Remove unportable assumptions about print widths of types like
3200 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3201 intptr_t when converting between pointer and integer, to avoid GCC
3202 warnings about wrong width.
3204 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3206 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3207 stack for each reader_thread, instead of defaulting to 8MB
3208 determined by the linker. This avoids failures in creating
3209 subprocesses on Windows 7, see the discussion in this thread:
3210 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3212 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3214 Fix up display of the *Minibuf-0* buffer in the mini window.
3215 * keyboard.c (read_char): Don't clear the echo area if there's no
3217 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3218 contents of *Minibuf-0*) if there's no message displayed in its stead.
3220 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3222 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3225 2012-05-06 Chong Yidong <cyd@gnu.org>
3227 * lisp.mk (lisp): Update.
3229 2012-05-05 Jim Meyering <meyering@redhat.com>
3231 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3233 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3235 * data.c (PUT_ERROR): New macro.
3236 (syms_of_data): Use it. Add new error type `user-error'.
3237 * undo.c (user_error): New function.
3238 (Fprimitive_undo): Use it.
3239 * print.c (print_error_message): Adjust print style for `user-error'.
3240 * keyboard.c (user_error): New function.
3241 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3243 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3245 Do not limit current-time-string to years 1000..9999.
3246 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3247 (Fcurrent_time_string): Support any year that is supported by the
3248 underlying localtime representation. Don't use asctime, as it
3249 has undefined behavior for years outside the range -999..9999.
3251 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3253 Fix race conditions involving setenv, gmtime, localtime, asctime.
3254 Without this fix, interrupts could mess up code that uses these
3255 nonreentrant functions, since setting TZ invalidates existing
3256 tm_zone or tzname values, and since most of these functions return
3257 pointers to static storage.
3258 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3259 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3260 Grow the critical sections to include not just invoking
3261 localtime/gmtime, but also accessing these functions' results
3262 including their tm_zone values if any, and any related TZ setting.
3263 (format_time_string): Last arg is now struct tm *, not struct tm **,
3264 so that the struct tm is saved in the critical section.
3265 All callers changed. Simplify allocation of initial buffer, partly
3266 motivated by the fact that memory allocation needs to be outside
3267 the critical section.
3269 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3271 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3272 with RESET_INTERVAL.
3274 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3275 Remove duplicated buffer name initialization.
3277 2012-05-02 Jim Meyering <jim@meyering.net>
3279 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3281 * xfns.c (x_window): Use xstrdup (Bug#11375).
3283 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3285 * xdisp.c (pos_visible_p): If already at a newline from the
3286 display string before the 'while' loop, don't walk back the glyphs
3287 from it3.glyph_row. Solves assertion violation when the display
3288 string begins with a newline (egg.el). (Bug#11367)
3290 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3292 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3295 2012-05-01 Glenn Morris <rgm@gnu.org>
3297 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3298 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3299 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3300 All were removed before 23.1.
3302 * dispnew.c: Remove HAVE_LIBNCURSES test;
3303 it is always true on relevant platforms.
3305 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3306 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3308 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3310 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3312 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3313 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3316 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3318 Do not avoid creating empty evaporating overlays (Bug#9642).
3319 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3320 That is, do not delete an evaporating overlay if it becomes
3321 empty after its bounds are adjusted to fit within its buffer.
3322 This fix caused other problems, and I'm reverting it until we get
3323 to the bottom of them.
3325 2012-04-27 Chong Yidong <cyd@gnu.org>
3327 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3329 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3331 * xdisp.c (pos_visible_p): If the window start position is beyond
3332 ZV, start the display from buffer beginning. Prevents assertion
3333 violation in init_iterator when the minibuffer window is scrolled
3336 * window.c (window_scroll_pixel_based): Likewise.
3338 2012-04-27 Chong Yidong <cyd@gnu.org>
3340 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3342 2012-04-27 Glenn Morris <rgm@gnu.org>
3344 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3345 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3347 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3349 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3350 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3352 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3354 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3355 display element, check also the underlying string or buffer
3356 character. (Bug#11341)
3358 * w32menu.c: Include w32heap.h.
3359 (add_menu_item): If the call to AppendMenuW (via
3360 unicode_append_menu) fails, disable Unicode menus only if we are
3361 running on Windows 9X/Me.
3363 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3365 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3366 (xgetint): Add missing shift for LSB tags.
3368 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3370 * keyboard.c (read_char): Don't wipe echo area for select window
3371 events: These might get delayed via `mouse-autoselect-window'
3374 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3376 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3377 manipulation of :loaded-from data.
3379 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3381 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3382 now a cons (bug#11311).
3384 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3386 Do not create empty overlays with the evaporate property (Bug#9642).
3387 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3388 if it becomes empty after its bounds are adjusted to fit within
3389 its buffer. Without this fix, in a nonempty buffer (let ((o
3390 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3391 yields an empty overlay that has the evaporate property, which is
3392 not supposed to happen.
3394 Fix minor GTK3 problems found by static checking.
3395 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3396 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3397 (struct _EmacsFixedClass, emacs_fixed_get_type):
3398 Move decls here from emacsgtkfixed.h, since they needn't be public.

3400 (emacs_fixed_class_init): Omit unused local.
3401 (emacs_fixed_child_type): Remove; unused.

3404 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
3405 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
3406 (EMACS_FIXED_GET_CLASS): Remove; unused.
3407 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
3409 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
3410 Problem reported by Juanma Barranquero for Windows -Wunused-function.
3412 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3414 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
3415 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
3416 (__malloc_size_t, __malloc_ptrdiff_t):
3417 Remove. All uses removed, replaced by the definiens if needed,
3418 since we can assume C89 or better now.
3419 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
3420 (protect_malloc_state, align, get_contiguous_space)
3421 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

3427 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
3428 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
3429 Define using prototypes, not old style.
3430 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
3431 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
3432 (align): Don't assume that signed integer overflow wraps around.
3433 Omit unused local var.
3434 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
3435 (_free_internal_nolock, memalign, mallochook, reallochook):
3436 Omit no-longer-needed casts.
3437 (valloc): Use getpagesize, not __getpagesize.
3438 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
3439 (struct hdr): The 'magic' member is now size_t, not unsigned long.
3441 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
3443 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
3445 Move functions from C to Lisp. Make non-blocking method calls
3446 the default. Implement further D-Bus standard interfaces.

3485 (Vdbus_registered_buses, Vdbus_registered_objects_table):
3488 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3490 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
3491 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
3492 Do not assume ptrdiff_t is the same width as 'int'.
3494 * alloc.c: Handle unusual debugging option combinations.
3495 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
3496 since the two debugging options are incompatible.
3497 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
3499 (mem_init, mem_insert, mem_insert_fixup):
3500 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
3501 (NEED_MEM_INSERT): Remove; no longer needed.
3503 2012-04-22 Leo Liu <sdl.web@gmail.com>
3505 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
3507 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3509 * sysdep.c [__FreeBSD__]: Minor cleanups.
3510 (list_system_processes, system_process_attributes) [__FreeBSD__]:
3511 Use Emacs indenting style more consistently. Avoid some casts.
3512 Use 'double' consistently rather than mixing 'float' and 'double'.
3514 2012-04-21 Eduard Wiebe <usenet@pusto.de>
3516 * sysdep.c (list_system_processes, system_process_attributes):
3517 Add implementation for FreeBSD (Bug#5243).
3519 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>
3521 * lisp.mk (lisp): Update.
3523 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
3525 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
3526 It is never used otherwise.

3530 * print.c (print_preprocess): Only check print_depth if print-circle
3532 (print_object): Check for cycles even when print-circle is nil and
3533 print-gensym is t, but only check print_depth if print-circle is nil.
3535 2012-04-20 Chong Yidong <cyd@gnu.org>
3537 * process.c (wait_reading_process_output): If EIO occurs on a pty,

3551 row, return zero immediately.
3552 (try_cursor_movement): If inside continuation line, don't back up
3553 farther than the first row after the header line, if any.
3554 Don't consider the header-line row as "partially visible", even if
3555 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
3557 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

3571 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
3572 -Wunused-result, -Wunused-variable. This should go away once
3573 the Emacs and Gnulib regex code is merged.

3592 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
3593 New extern decls, to avoid calling undeclared functions.
3594 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
3595 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3596 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
3597 (NEED_MEM_INSERT): New macro.
3598 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
3599 Remove one incorrect comment and fix another.

3613 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
3614 Remove decls. This fixes an "It stinks!".

3618 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
3620 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

3633 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
3634 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
3635 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
3636 * s/netbsd.h, s/sol2-6.h:
3637 Remove definition of GC_MARK_STACK, since the default now works.
3638 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
3639 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
3640 no longer the default.
3641 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
3643 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3645 * lread.c (lisp_file_lexically_bound_p):

3666 2012-04-11 Daniel Colascione <dancol@dancol.org>
3668 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3669 against is gone. It's better to use vfork now so that when Cygwin
3670 gains a new, working vfork, we use it automatically (bug#10398).
3672 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

3690 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
3692 * w32.c (w32_delayed_load): Record the full path of the library
3693 being loaded (bug#10424).
3695 2012-04-09 Glenn Morris <rgm@gnu.org>
3697 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
3698 not just in the obarray, before snarfing them. (Bug#11036)
3700 * Makefile.in ($(leimdir)/leim-list.el):
3701 Pass EMACS rather than BUILT_EMACS.

3710 Add convenience `GNUTLS_LOG2i' macro.
3712 * gnutls.c (gnutls_log_function2i): Convenience log function.
3713 (emacs_gnutls_read): Use new log functions,
3714 `gnutls_handshakes_tried' process member, and

3725 * minibuf.c (Fread_variable): Callers changed.
3727 2012-04-09 Eli Zaretskii <eliz@gnu.org>
3729 * xdisp.c (set_cursor_from_row): If the display string appears in
3730 the buffer at position that is closer to point than the position
3731 after the display string, display the cursor on the first glyph of
3732 the display string. Fixes cursor display when a 'display' text
3733 property immediately follows invisible text. (Bug#11094)
3735 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
3737 composite.c: use 'double' consistently
3738 * composite.c (get_composition_id): Use 'double' consistently
3739 instead of converting 'float' to 'double' and vice versa; this is
3740 easier to understand and avoids a GCC warning.
3742 2012-04-09 Glenn Morris <rgm@gnu.org>
3744 * Makefile.in: Generate leim-list with bootstrap-emacs, in
3745 preparation for dumping it with emacs. (Bug#4789)

3767 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
3768 (mark_memory): Mark Lisp_Objects only if pointers might hide in
3769 objects, as mark_maybe_pointer will catch them otherwise.
3770 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
3771 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
3773 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
3775 Fix typo that broke non-Windows builds.
3776 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

3786 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
3787 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
3788 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
3789 [!WINDOWSNT]: New macros.
3790 (init_libxml2_functions, libxml2_loaded_p): New functions.
3791 (parse_region): Call fn_xmlCheckVersion instead of using the macro
3792 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
3793 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
3794 Calls xmlCleanupParser only if libxml2 was loaded (or statically
3796 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
3797 Call init_libxml2_functions before calling libxml2 functions.
3798 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
3800 * emacs.c: Don't include libxml/parser.h.
3801 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
3802 xmlCleanupParser directly.
3804 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
3806 2012-04-07 Eli Zaretskii <eliz@gnu.org>

3814 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
3815 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
3816 about subtle differences between FETCH_CHAR* and STRING_CHAR*
3817 macros related to unification of CJK characters. For the details,
3818 see the discussion following the message here:
3819 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
3821 2012-04-04 Chong Yidong <cyd@gnu.org>
3823 * keyboard.c (Vdelayed_warnings_list): Doc fix.
3825 2012-04-01 Eli Zaretskii <eliz@gnu.org>
3827 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

3835 2012-03-31 Eli Zaretskii <eliz@gnu.org>
3837 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
3838 position we get to after a call to move_it_to fails the
3839 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
3840 only if we wind up in a string from display property. (Bug#11063)
3842 * window.c (Fdelete_other_windows_internal): Invalidate the row
3843 and column information about mouse highlight, so that redisplay
3844 restores it after reallocating the glyph matrices. (Bug#7464)
3846 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
3847 string comes from a `display' text property, use the buffer
3848 position of that property as if we actually saw that position in
3850 (move_it_by_lines): Remove the assertion that
3851 "it->current_x == 0 && it->hpos == 0" which can be legitimately
3852 violated when there's a before-string at the beginning of a line.
3855 2012-03-30 Eli Zaretskii <eliz@gnu.org>
3857 * xdisp.c (append_space_for_newline): If the default face was
3858 remapped, use the remapped face for the appended newline.
3859 (extend_face_to_end_of_line): Use the remapped default face for
3860 extending the face to the end of the line.
3861 (display_line): Call extend_face_to_end_of_line when the default
3862 face was remapped. (Bug#11068)

3890 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
3892 2012-03-25 Kenichi Handa <handa@m17n.org>
3894 * dispextern.h (struct glyph): Change the bit length of
3895 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
3897 2012-03-24 Eli Zaretskii <eliz@gnu.org>
3899 * s/ms-w32.h (tzname): Include time.h before redirecting to
3900 _tzname. Fixes the MSVC build. (Bug#9960)

3904 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
3907 * xterm.c (XTread_socket): Only modify handling_signal if
3908 !SYNC_INPUT. (Bug#11080)
3910 2012-03-23 Eli Zaretskii <eliz@gnu.org>
3912 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
3913 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
3914 when fetching a multibyte character consumes more bytes than
3915 CHAR_BYTES returns, due to unification of CJK characters in
3916 string_char. (Bug#11073)
3918 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
3920 * process.c (wait_reading_process_output): Handle pty disconnect

3932 2012-03-21 Chong Yidong <cyd@gnu.org>
3934 * xfaces.c (Vface_remapping_alist): Doc fix.
3936 2012-03-20 Eli Zaretskii <eliz@gnu.org>
3938 * w32proc.c (Fw32_set_console_codepage)
3939 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

3952 2012-03-18 Eli Zaretskii <eliz@gnu.org>
3954 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
3955 that is not from display property, accept the row as a "cursor
3956 row" if one of the string's character has a non-nil `cursor'
3957 property. Fixes cursor positioning when there are newlines in
3958 overlay strings, e.g. in icomplete.el. (Bug#11035)
3960 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

3966 * eval.c (inhibit_lisp_code): Rename from
3967 inhibit_window_configuration_change_hook; move from window.c.
3969 * xfns.c (unwind_create_frame_1, Fx_create_frame):
3970 * window.c (run_window_configuration_change_hook)
3971 (syms_of_window): Callers changed.
3973 2012-03-11 Chong Yidong <cyd@gnu.org>
3975 * keymap.c (Fkey_description): Doc fix (Bug#9700).

3982 is visible (Bug#10955).
3984 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
3986 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
3988 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
3990 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
3991 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
3994 2012-03-03 Glenn Morris <rgm@gnu.org>
3996 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
3998 2012-03-02 Eli Zaretskii <eliz@gnu.org>
4000 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4001 position past the first glyph_row that ends at ZV. (Bug#10902)
4002 (redisplay_window, next_element_from_string): Fix typos in
4004 (redisplay_window): Pass to move_it_vertically the margin in
4005 pixels, not in screen lines.
4007 2012-03-02 Glenn Morris <rgm@gnu.org>
4009 * buffer.c (buffer-list-update-hook): Doc fix.
4011 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4013 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4014 push_it before setting up the iterator for the first overlay
4015 string, even if we have an empty string loaded.

4017 stack, pop the stack. (Bug#10903)
4019 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4021 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4022 Suggested by Stefan Monnier in
4023 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4024 * alloc.c (widen_to_Lisp_Object): New static function.
4025 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4026 and widening them to Lisp_Objects. This would work even if
4027 USE_LSB_TAG is defined and wide integers are used, which might
4028 happen in a future version of Emacs.
4030 2012-02-25 Chong Yidong <cyd@gnu.org>
4032 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4035 * xselect.c (Fx_selection_exists_p): Doc fix.
4036 (x_clipboard_manager_save_all): Print an informative message
4037 before saving to clipboard manager.
4039 2012-02-24 Chong Yidong <cyd@gnu.org>
4041 * keyboard.c (process_special_events): Handle all X selection
4042 requests in kbd_buffer, not just the next one (Bug#8869).
4044 2012-02-23 Chong Yidong <cyd@gnu.org>
4046 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4047 call when setting menu-bar-lines and tool-bar-lines parameters.
4048 (unwind_create_frame_1): New helper function.
4050 * window.c (inhibit_window_configuration_change_hook): New var.
4051 (run_window_configuration_change_hook): Obey it.
4052 (syms_of_window): Initialize it.
4054 2012-02-22 Chong Yidong <cyd@gnu.org>
4056 * xterm.c (x_draw_image_relief): Add missing type check for

4068 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4069 when computing $valmask.
4071 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4072 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4073 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4074 It's useless in that case, and it can cause problems on hosts
4075 that allocate halves of EMACS_INT values separately.
4076 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4077 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4078 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4079 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4080 it avoids undefined behavior on hosts where shifting right by more
4081 than the word width has undefined behavior.
4083 2012-02-19 Chong Yidong <cyd@gnu.org>
4085 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

4128 * window.c (Fdelete_window_internal): Invalidate the mouse
4129 highlight (Bug#9904).
4131 2012-02-12 Glenn Morris <rgm@gnu.org>

4161 2012-02-07 Chong Yidong <cyd@gnu.org>
4163 * buffer.c (Fbuffer_local_variables)
4164 (buffer_lisp_local_variables): Handle unbound vars correctly;
4165 don't let Qunbound leak into Lisp.
4167 2012-02-07 Glenn Morris <rgm@gnu.org>
4169 * image.c (Fimagemagick_types): Doc fix.
4171 * image.c (imagemagick-render-type): Change it from a lisp object

4207 * character.c (char_width): Return EMACS_INT, not int.
4208 (char_width, c_string_width): Check for overflow when
4209 computing the width; this is possible now that individual
4210 characters can have unbounded width. Problem introduced
4211 by merge from Emacs 23 on 2012-01-19.

4883 behave as if the cursor position were at the window margin.
4885 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
4886 and the cursor position is out of bounds, behave as if the cursor

4917 * dispnew.c (verify_row_hash): Call row_hash for computing the
4918 hash code of a row, instead of duplicating code from xdisp.c.
4920 * dispextern.h (row_hash): Add prototype.
4922 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

5027 Avoid some portability problems by eschewing 'extern inline' functions.
5028 The trivial performance wins aren't worth the portability hassles; see
5029 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
5031 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

5079 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
5080 This is also needed for porting to any host where GC_MARK_STACK is
5081 not GC_MAKE_GCPROS_NOOPS.
5082 (which_symbols): Use it.
5084 2011-11-07 Kenichi Handa <handa@m17n.org>

5097 * xmenu.c (cleanup_widget_value_tree): New function.
5098 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

5105 (window_box_width, window_box_left, window_box_left_offset)
5106 (window_box_right, window_box_right_offset): Declare extern.
5107 Otherwise, these inline functions do not conform to C99 and
5108 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5109 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5110 * intervals.c (adjust_intervals_for_insertion)
5111 (adjust_intervals_for_deletion): Now extern, because otherwise the
5112 extern inline functions 'offset_intervals' couldn't refer to it.
5113 (static_offset_intervals): Remove.
5114 (offset_intervals): Rewrite using the old contents of
5115 static_offset_intervals. The old version didn't conform to C99
5116 because an extern inline function contained a reference to an
5117 identifier with static linkage.
5119 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
5121 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

5139 (Fwindow_vscroll): Doc fix.
5140 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
5141 argument, since it makes no sense to pass a live window and for
5142 consistency with window-child.

5172 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
5173 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
5174 Move terminal->reference_count++ just before making the frame official

5288 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
5289 so that this new function doesn't get optimized away by a
5290 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
5292 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>

5317 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5319 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

5429 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5430 * editfns.c: Rewrite current-time-zone so that it invokes
5431 the equivalent of (format-time-string "%Z") to get the time zone name.
5432 This fixes a bug when the time zone name contains characters that
5433 need converting from the system time locale to Emacs internal format.
5434 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5435 that patch fixed format-time-string to do the conversion, but
5436 I forgot to fix current-time-zone.
5437 (format_time_string): New function, containing most of
5438 what Fformat_time_string used to contain.
5439 (Fformat_time_string): Rewrite in terms of format_time_string.

5443 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5444 Jason Rumney's 2007-06-07 change worked around this bug, but
5446 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5448 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5450 * xdisp.c (start_display): If the character at POS is displayed
5451 via a display vector, reset IT->current.dpvec_index to zero.
5452 (try_window_reusing_current_matrix): If a line ends in a display
5453 vector or the next line starts in a display vector, continue
5454 redrawing the window even though the character position of
5455 start_row was reached.
5458 2011-10-18 Chong Yidong <cyd@gnu.org>
5460 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5461 with nobreak-char-display too.
5463 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5465 Fix part 3 of bug#9771.
5466 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5467 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5468 non-neutral characters if the current character is a paragraph
5469 separator (a.k.a. Newline). This avoids running the same
5470 expensive loop twice, once when we consume the preceding newline
5471 and the other time when the line actually needs to be displayed.
5472 Avoid the loop when we see neutrals on the base embedding level
5473 following a character whose directionality is the same as the
5474 paragraph's. This avoids running the expensive loop when a line
5475 ends in a long sequence of neutrals, like control characters.
5476 Add assertion against STRONG_AL type. Slightly rearrange code
5477 that determines the type of a neutral given the first non-neutral
5479 (bidi_level_of_next_char): Set next_en_pos to zero when
5480 invalidating its info.
5482 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5484 * xdisp.c (push_display_prop): Determine whether to record string
5485 or buffer position by IT->string, not by IT->method. Allow
5486 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5487 (move_it_vertically_backward): Don't look for character position
5488 immediately after the newline when in a continuation line.
5491 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5493 * window.c (coordinates_in_window): Rewrite and delabelize
5494 vertical border check. (Bug#5357) (Bug#9618)
5496 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5498 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5499 errors in XSetWindowBorder (bug#9310).
5501 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5503 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5504 avoid crash when xmalloc overrun checking is enabled.
5506 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5508 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5509 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5510 cursor motion with <left> and <right> arrow keys.
5512 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5513 some callers set that themselves.
5515 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5517 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5518 display string and the previous row comes from the same string and
5519 is empty. (Bug#9739) (Bug#9738)
5521 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5523 * doc.c (get_doc_string): Encode file name (bug#9735).
5525 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5527 * bidi.c (bidi_level_of_next_char):
5528 * xdisp.c (get_visually_first_element): Remove old incorrect
5529 comments regarding the Unicode Line Separator character.
5531 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5533 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5535 * alloc.c (Fgc_status): Do not access beyond zombies array
5536 boundary if nzombies > MAX_ZOMBIES.
5537 * alloc.c (dump_zombies): Add missing format specifier.
5539 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5541 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5542 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5544 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5545 Some packages use them to denote characters with modifiers.
5547 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5549 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5550 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5551 matching a pp-number. Rename parameter var to var1.
5553 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5555 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5557 2011-10-08 Glenn Morris <rgm@gnu.org>
5559 * callint.c (Fcall_interactively): Give a more explicit error for the
5560 'c' case with a non-character input. (Bug#8479)
5562 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5564 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5566 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5567 lines that are hscrolled on the left.
5569 * dispnew.c (buffer_posn_from_coords): Account for a possible
5570 presence of header-line. (Bug#4426)
5572 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5574 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5575 Don't advertise functionality which we discourage or doesn't work.
5577 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5579 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5580 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5581 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5582 this makes Emacs dump core during garbage collection on rare
5583 occasions. sizeof is obviously inferior to offsetof here, so
5584 stick with offsetof.
5585 (GC_POINTER_ALIGNMENT): New macro.
5586 (mark_memory): Omit 3rd (offset) arg; caller changed.
5587 Don't assume EMACS_INT alignment is the same as pointer alignment.
5589 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5591 * keyboard.c (read_key_sequence_remapped): New var.
5592 (read_key_sequence): Compute remapping in the right buffer.
5593 (command_loop_1): Use read_key_sequence's remapping directly.
5595 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5597 * dired.c (file_name_completion): Don't expand file name.
5598 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5599 before checking file name handler.
5601 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5602 they've been requested explicitly (bug#9591).
5604 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5606 * keymap.c (Fsingle_key_description): Use make_specified_string
5607 instead of build_string to build string from push_key_description.
5610 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5612 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5613 This fixes a Y2038 bug on 64-bit hosts.
5614 * buffer.c (reset_buffer):
5615 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5616 (Fclear_buffer_auto_save_failure):
5617 Use 0, not -1, to represent an unset failure time, since time_t
5618 might not be signed.
5620 Remove dependency on glibc malloc internals.
5621 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5622 Move back here from lisp.h, but with their new implementations.
5623 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5624 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5625 * charset.c (charset_table_init): New static var.
5626 (syms_of_charset): Use it instead of xmalloc. This removes a
5627 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5628 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
5629 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5630 Move back to alloc.c.
5631 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5632 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
5634 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
5636 * nsterm.m (windowDidResize): Call x_set_window_size only when
5637 ns_in_resize is true. Otherwise set pixelwidth/height and
5638 call change_frame_size (Bug#9628).
5640 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5642 Port --enable-checking=all to Fedora 14 x86-64.
5643 * charset.c (syms_of_charset): Also account for glibc malloc's
5644 internal overhead when calculating the initial malloc maximum.
5646 Port --enable-checking=all to Fedora 14 x86.
5647 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5649 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5650 (overrun_check_realloc, overrun_check_free):
5651 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5652 That way, xmalloc returns a properly-aligned pointer even if
5653 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
5654 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5655 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5656 into account when calculating the initial malloc maximum.
5657 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5658 Move here from alloc.c, so that charset.c can use it too.
5659 Properly align; the old code wasn't right for common 32-bit hosts
5660 when configured with --enable-checking=all.
5661 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5662 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
5664 2011-09-29 Eli Zaretskii <eliz@gnu.org>
5666 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
5669 2011-09-28 Eli Zaretskii <eliz@gnu.org>
5671 * xdisp.c (compute_display_string_end): If there's no display
5672 string at CHARPOS, return -1.
5674 * bidi.c (bidi_fetch_char): When compute_display_string_end
5675 returns a negative value, treat the character as a normal
5676 character not covered by a display string. (Bug#9624)
5678 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
5680 * lread.c (Fread_from_string): Fix typo in docstring.
5682 2011-09-27 Eli Zaretskii <eliz@gnu.org>
5684 * xdisp.c (handle_invisible_prop): If invisible text ends on a
5685 newline, reseat the iterator instead of bidi-iterating there one
5686 character at a time. (Bug#9610)
5687 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
5688 TO_CHARPOS if the bidi iterator is at base embedding level.
5690 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
5692 * lread.c (readevalloop): Use correct code for NBSP.
5693 (read1): Likewise. (Bug#9608)
5695 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
5697 * dbusbind.c (Fdbus_register_signal): When service is not
5698 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
5700 2011-09-25 Glenn Morris <rgm@gnu.org>
5702 * buffer.c (truncate-lines): Doc fix.
5704 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
5706 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
5707 (Fset_window_next_buffers): Doc fix.
5709 2011-09-24 Glenn Morris <rgm@gnu.org>
5711 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
5713 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
5715 Fix minor problems found by static checking.
5716 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
5717 * indent.c (Fvertical_motion): Fix == vs = typo.
5719 2011-09-24 Eli Zaretskii <eliz@gnu.org>
5721 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
5722 Default value is now t. Doc fix.
5724 * indent.c (Fvertical_motion): Compute and apply the overshoot
5725 logic when moving up, not only when moving down. Fix the
5726 confusing name and values of the it_overshoot_expected variable;
5727 logic changes accordingly. (Bug#9254) (Bug#9549)
5729 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
5730 CHARPOS is covered by a display string which includes newlines.
5731 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
5732 is covered by a display string with embedded newlines.
5734 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
5736 * dbusbind.c (Fdbus_register_signal): Add match rule to
5737 Vdbus_registered_objects_table. (Bug#9581)
5738 (Fdbus_register_method, Vdbus_registered_objects_table):
5741 2011-09-24 Jim Meyering <meyering@redhat.com>
5743 do not ignore write error for any output size
5744 The previous change was incomplete.
5745 While it makes emacs --batch detect the vast majority of stdout
5746 write failures, errors were still ignored whenever the output size is
5747 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
5748 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
5749 && echo FAIL: ignored write error
5750 FAIL: ignored write error
5751 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
5752 && echo FAIL: ignored write error
5753 FAIL: ignored write error
5754 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
5756 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

5759 non-successfully if a write error occurred on stdout. (Bug#9574)
5761 2011-09-21 Eli Zaretskii <eliz@gnu.org>
5763 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
5766 * dispextern.h (struct it): Update the comment documenting what
5769 2011-09-20 Eli Zaretskii <eliz@gnu.org>
5771 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
5772 a display string, extend search for cursor position to end of row.
5773 (find_row_edges): If the row ends in a newline from a display
5774 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
5775 Handle the case of a display string with multiple newlines.
5776 (Fcurrent_bidi_paragraph_direction): Fix search for previous
5777 non-empty line. Fixes confusing cursor motion with arrow keys at
5778 the beginning of a line that starts with whitespace.

5790 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5792 * xdisp.c (display_line): Record maximum and minimum buffer
5793 positions even if no glyphs were produced (e.g., by a zero-width
5794 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
5795 buffer positions that will be removed from the glyph row because
5797 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
5798 column is beyond frame width: don't subtract 1 "pixel" when
5799 computing width of the stretch.
5800 (reseat_at_next_visible_line_start): Undo the change made on
5801 2011-09-17 that saved paragraph information and restored it after
5802 the call to `reseat'. (Bug#9545)
5804 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5806 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
5807 and turn window cursor on if cleared (Bug#9415).

5820 Fix minor problem found by static checking.
5821 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
5822 initialized, to pacify gcc -Wuninitialized.
5824 * fileio.c: Report proper errno when syscall falls.
5825 (Finsert_file_contents): Save and restore errno,
5826 so that report_file_error outputs the correct diagnostic.
5827 (Fwrite_region) [CLASH_DETECTION]: Likewise.
5829 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5831 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
5833 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5835 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
5836 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
5838 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5840 * xdisp.c (reseat_at_next_visible_line_start): Keep information
5841 about the current paragraph and restore it after the call to reseat.
5843 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
5844 (bidi_find_paragraph_start): Search back for paragraph beginning
5845 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
5846 (bidi_move_to_visually_next): Only trigger paragraph-related
5847 computations when the last character is a newline or at EOB, not
5848 just any NEUTRAL_B. (Bug#9470)
5850 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
5851 truncated lines if point is covered by a display string. (Bug#9524)

5855 * xselect.c: Relax test for outgoing X longs (Bug#9498).
5856 (cons_to_x_long): New function.
5857 (lisp_data_to_selection_data): Use it. Correct the test for
5858 short-versus-long data; it was negated. Break out of vector
5859 loop, for efficiency, when a long datum is discovered.
5861 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
5863 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
5865 2011-09-16 Eli Zaretskii <eliz@gnu.org>
5867 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

5891 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
5892 This occurs when processing a multibyte format.
5893 Problem reported by Wolfgang Jenker.
5895 2011-09-15 Johan Bockgård <bojohan@gnu.org>
5897 * xdisp.c (try_cursor_movement): Only check for exact match if
5898 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
5900 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>

5910 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5912 * xselect.c: Use signed conversions more consistently (Bug#9498).
5913 (selection_data_to_lisp_data): Assume incoming selection data are
5914 signed integers, not unsigned. This is to be consistent with
5915 outgoing selection data, which was modified to use signed integers
5916 in as part of the fix to Bug#9196 in response to Jan D.'s comment
5917 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11

5946 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
5948 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
5950 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
5951 value for non-existent files.
5953 2011-09-11 Eli Zaretskii <eliz@gnu.org>
5955 * fileio.c (Finsert_file_contents): If the file cannot be opened,
5956 set its "size" to -1. This will set the modtime_size field of
5957 the corresponding buffer to -1, which is what
5958 verify-visited-file-modtime expects for files that do not exist.
5961 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
5963 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
5965 * lisp.h: ... from here. push_key_description is no longer
5966 defined in keyboard.c, so its declaration should not be in
5967 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
5968 logically belongs with push_key_description.
5970 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
5972 * buffer.h: Include <sys/types.h> instead of <time.h>.
5973 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
5974 Problem reported by Herbert J. Skuhra.
5976 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
5978 * xml.c (parse_region): Make the parsing work for
5979 non-comment-starting XML files again (bug#9144).
5981 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
5983 * image.c (gif_load): Fix calculation of bottom and right corner.
5986 2011-09-10 Eli Zaretskii <eliz@gnu.org>
5988 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
5989 redisplay in small windows.
5991 2011-09-09 Eli Zaretskii <eliz@gnu.org>
5993 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
5995 2011-09-08 Martin Rudalics <rudalics@gmx.at>
5997 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
5998 Operate on live windows only.
6000 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6002 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6004 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6006 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6007 only under bidi iteration.
6009 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6011 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6013 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6015 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6016 Without this fix, the command to link temacs failed due to an
6017 undefined symbol __builtin_isnan. This is because
6018 /usr/include/iso/math_c99.h #defines isnan(x) to
6019 __builtin_isnan(x), but the bundled gcc, which identifies itself
6020 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6022 * floatfns.c (isnan): #undef, and then #define to a clone of
6024 (Fisnan): Always define, since it's always available now.
6025 (syms_of_floatfns): Always define isnan at the Lisp level.
6027 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6029 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6031 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6033 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6034 The previous code assumed that file offsets (off_t values) fit in
6035 EMACS_INT variables, which is not true on typical 32-bit hosts.
6036 The code messed up by falsely reporting buffer overflow in cases
6037 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6038 when "big" contains more than 2**29 bytes, even though this
6039 inserts just one byte and does not overflow the buffer.
6040 (Finsert_file_contents): Store file offsets as off_t
6041 values, not as EMACS_INT values. Check for overflow when
6042 converting between EMACS_INT and off_t. When checking for
6043 buffer overflow or for overlap, take the offsets into account.
6044 Don't use EMACS_INT for small values where int suffices.
6045 When checking for overlap, fix a typo: ZV was used where
6046 ZV_BYTE was intended.
6047 (Fwrite_region): Don't assume off_t fits into 'long'.
6048 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6050 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6052 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6054 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6056 sprintf-related integer and memory overflow issues (Bug#9412).
6058 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6059 (esprintf, exprintf, evxprintf): New functions.
6060 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6061 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6062 (modify_event_symbol): Do not assume that the length of
6063 name_alist_or_stem is safe to alloca and fits in int.
6064 (Fexecute_extended_command): Likewise for function name and binding.
6065 (Frecursion_depth): Wrap around reliably on integer overflow.
6066 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6067 since some callers pass EMACS_INT values.
6068 (Fsingle_key_description): Don't crash if symbol name contains more
6069 than MAX_ALLOCA bytes.
6070 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6071 (get_minibuffer): Arg is now EMACS_INT, not int.
6072 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6073 (esprintf, exprintf, evxprintf): New decls.
6074 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6076 * dbusbind.c (signature_cat): New function.
6077 (xd_signature, Fdbus_register_signal):
6078 Do not overrun buffer; instead, report string overflow.
6080 * dispnew.c (add_window_display_history): Don't overrun buffer.
6081 Truncate instead; this is OK since it's just a log.
6083 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6084 even if the time zone offset is outlandishly large.
6085 Don't mishandle offset == INT_MIN.
6087 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6088 when creating daemon; the previous buffer-overflow check was incorrect.
6090 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6091 which has the guts of the old verror function.
6093 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6094 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6096 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6097 (font_unparse_xlfd): Don't blindly alloca long strings.
6098 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6099 fits in int, when using sprintf. Use single snprintf to count
6100 length of string rather than counting it via multiple sprintfs;
6101 that's simpler and more reliable.
6102 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6103 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6104 sprintf, in case result does not fit in int.
6106 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6107 (fontset_from_font): Print it.
6109 * frame.c (tty_frame_count): Now printmax_t, not int.
6110 (make_terminal_frame, set_term_frame_name): Print it.
6111 (x_report_frame_params): In X, window IDs are unsigned long,
6112 not signed long, so print them as unsigned.
6113 (validate_x_resource_name): Check for implausibly long names,
6114 and don't assume name length fits in 'int'.
6115 (x_get_resource_string): Don't blindly alloca invocation name;
6116 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6119 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6120 (xg_check_special_colors, xg_set_geometry):
6121 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6123 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6124 Use esprintf, not sprintf, in case result does not fit in int.
6126 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6127 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6128 it as a large positive number.
6129 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6130 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6132 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6133 in case result does not fit in int.
6135 * print.c (float_to_string): Detect width overflow more reliably.
6136 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6137 buffer overrun. Don't assume list length fits in 'int'. Treat
6138 print length of 0 as 0, not as infinity; to be consistent with other
6139 uses of print length in this function. Don't overflow print length
6140 index. Don't assume hash table size fits in 'long', or that
6141 vectorlike size fits in 'unsigned long'.
6143 * process.c (make_process): Use printmax_t, not int, to format
6144 process-name gensyms.
6146 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6148 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6149 to avoid potential buffer overrun.
6151 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6152 if X resource line is longer than 512 bytes.
6154 * xfns.c (x_window): Make sprintf buffer a bit bigger
6155 to avoid potential buffer overrun.
6157 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6159 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6161 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6163 Integer overflow fixes for scrolling, etc.
6164 Without these, Emacs silently mishandles large integers sometimes.
6165 For example, "C-u 4294967297 M-x recenter" was treated as if
6166 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6168 * xdisp.c (try_window_id): Check Emacs fixnum range before
6169 converting to 'int'.
6171 * window.c (window_scroll_line_based, Frecenter):
6172 Check that an Emacs fixnum is in range before assigning it to 'int'.
6173 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6174 values converted from Emacs fixnums.
6175 (Frecenter): Don't wrap around a line count if it is out of 'int'
6176 range; instead, treat it as an extreme value.
6177 (Fset_window_configuration, compare_window_configurations):
6178 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6180 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6181 that can exceed INT_MAX. Check that EMACS_INT value is in range
6182 before assigning it to the (possibly-narrower) index.
6183 (match_limit): Don't assume that a fixnum can fit in 'int'.
6185 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6188 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6189 (Fvertical_motion): Don't wrap around LINES values that don't fit
6190 in 'int'. Instead, treat them as extreme values. This is good
6191 enough for windows, which can't have more than INT_MAX lines anyway.
6193 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6195 * Require libxml/parser.h to avoid compilation warning.
6197 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6199 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6200 since this reportedly can destroy thread storage.
6202 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6204 * syntax.c (find_defun_start): Update all cache variables if
6205 exiting early (Bug#9401).
6207 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6209 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6211 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6212 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6213 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6215 * term.c (tty_append_glyph): New function.
6216 (produce_stretch_glyph): Static function and its prototype deleted.
6218 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6221 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6223 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6224 when checking :margin (Bug#9390).
6225 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6226 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6227 so that the name doesn't mislead. All uses changed.
6229 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6231 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6234 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6236 * xdisp.c (move_it_to): Don't bail out early when reaching
6237 position beyond to_charpos, if we are scanning backwards.
6238 (move_it_vertically_backward): When DY == 0, make sure we get to
6239 the first character in the line after the newline.
6241 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6243 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6244 (ccl_driver): Do not generate an out-of-range pointer.
6245 (Fccl_execute_on_string): Remove unnecessary check for
6246 integer overflow, noted by Stefan Monnier in
6247 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6248 Remove a FIXME that didn't need fixing.
6249 Simplify the newly-introduced buffer reallocation code.
6251 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6253 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6255 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6257 Integer and memory overflow issues (Bug#9196).
6259 * doc.c (get_doc_string): Rework so that
6260 get_doc_string_buffer_size is the actual buffer size, rather than
6261 being 1 less than the actual buffer size; this makes xpalloc more
6264 * image.c (x_allocate_bitmap_record, cache_image):
6265 * xselect.c (Fx_register_dnd_atom):
6266 Simplify previous changes by using xpalloc.
6268 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6269 since either will do and ptrdiff_t is convenient with xpalloc.
6271 * charset.c (charset_table_size)
6272 (struct charset_sort_data.priority): Now ptrdiff_t.
6273 (charset_compare): Don't overflow if priorities differ greatly.
6274 (Fsort_charsets): Don't assume list length fits in int.
6275 Check for size-calculation overflow when allocating sort data.
6276 (syms_of_charset): Allocate an initial charset table that is
6277 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6279 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6281 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6282 The actual value is always <= INT_MAX, and leaving it unsigned made
6283 overflow checking harder.
6285 * dispextern.h (struct glyph_matrix.rows_allocated)
6286 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6287 with xpalloc. The values are still always <= INT_MAX.
6289 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6291 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6292 (SAFE_NALLOCA): New macro.
6294 * region-cache.c (struct boundary.pos, find_cache_boundary)
6295 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6296 (set_cache_region, invalidate_region_cache)
6297 (revalidate_region_cache, know_region_cache, region_cache_forward)
6298 (region_cache_backward, pp_cache):
6299 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6300 so that ptrdiff_t * can be passed to xpalloc.
6301 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6302 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6303 (pp_cache): Don't assume cache_len fits in int.
6304 * region-cache.h: Adjust extern decls to match.
6306 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6307 EMACS_INT, since either will do, for xpalloc.
6309 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6310 (xnmalloc, xnrealloc, xpalloc): New functions.
6312 * bidi.c (bidi_shelve_header_size): New constant.
6313 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6314 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6316 * bidi.c (bidi_cache_shrink):
6317 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6319 Don't update size of array until after memory allocation succeeds,
6320 because xmalloc/xrealloc may not return.
6321 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6322 now that we have proper integer overflow checking.
6323 (record_overlay_string, overlay_strings): Catch overflows when
6324 calculating size of overlay_str_buf.
6326 * callproc.c (Fcall_process): Check for size overflow when
6327 calculating size of args2.
6328 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6329 Normally we prefer signed values, but sticking with ptrdiff_t would
6330 require adding more-complicated checks.
6332 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6333 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6334 Redo buffer-overflow calculations to avoid integer overflow.
6335 Add a FIXME comment where memory seems to be over-allocated.
6337 * character.c (Fstring): Check for size-calculation overflow.
6339 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6340 unnecessary integer overflow. Check for size overflow.
6341 (encode_coding_object): Don't update size until xmalloc succeeds.
6343 * composite.c (get_composition_id): Check for overflow in glyph
6344 length calculations.
6346 Integer and memory overflow fixes for display code.
6347 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
6348 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6349 (scrolling_window): Check for overflow in size calculations.
6350 (line_draw_cost, realloc_glyph_pool, add_row_entry):
6351 Don't assume glyph table len fits in int.
6352 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
6353 (row_table_size): Now ptrdiff_t, not int.
6354 (scrolling_window): Avoid overflow in size calculations.
6355 Don't update size until allocation succeeds.
6356 * fns.c (concat): Check for overflow in size calculations.
6357 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
6358 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6359 (NEXT_ALMOST_PRIME_LIMIT): New constant.
6361 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
6362 (get_doc_string): Check for size calculation overflow.
6363 Don't update size until allocation succeeds.
6364 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
6365 EMACS_INT, where ptrdiff_t will do.
6366 (Fsubstitute_command_keys): Check for string overflow.
6368 * editfns.c (set_time_zone_rule): Don't assume environment length
6370 (message_length): Now ptrdiff_t, not int.
6371 (Fmessage_box): Don't update size until allocation succeeds.
6372 Don't assume message length fits in int.
6373 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6375 * emacs.c (main): Do not reallocate argv, since there is a null at
6376 the end that can be overwritten, and this way there's no need to
6377 worry about size-calculation overflow.
6378 (sort_args): Check for size-calculation overflow.
6380 * eval.c (init_eval_once, grow_specpdl): Don't update size until
6382 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
6384 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
6385 (x_set_scroll_bar_width, x_figure_window_size):
6386 Check for integer overflow.
6387 (x_set_alpha): Do not assume XINT fits in int.
6389 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6390 This is for the members text_lines, text_cols, total_lines, total_cols,
6391 where the system imposes an 'int' limit.
6393 * fringe.c (Fdefine_fringe_bitmap):
6394 Don't update size until alloc works.
6396 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
6397 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
6399 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
6400 Check for size-calculation overflow.
6401 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6402 do, as we prefer signed integers.
6403 (id_to_widget.max_size, id_to_widget.used)
6404 (xg_store_widget_in_map, xg_remove_widget_from_map)
6405 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
6406 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
6407 Use and return ptrdiff_t, not int.
6408 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
6409 * gtkutil.h: Change prototypes to match the above.
6411 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
6412 are duplicate now that they've been promoted to lisp.h.

6456 (Fset_match_data): Don't assume list lengths fit in 'int'.
6458 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
6459 for command line length. Do not attempt to address one before the

6500 (xg_select): Check for size calculation overflow.
6501 Don't update size until alloc done.
6503 * xrdb.c (get_environ_db): Don't assume path length fits in int,

6506 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
6507 (X_LONG_MIN): New macros.
6508 Use them to make the following changes clearer.
6509 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6510 This change doesn't affect the value now, but it may help remind
6511 future maintainers not to raise the value too much later.
6512 (SELECTION_QUANTUM): Remove, replacing with ...
6513 (selection_quantum): ... new function, which avoids overflow.
6515 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

6533 Don't store size until memory allocation succeeds.
6534 (x_get_window_property): Plug memory leak on memory exhaustion.
6535 Don't double-block input; malloc is safe here. Don't assume 2**34
6536 - 4 fits in unsigned long. Add an xassert to check
6537 XGetWindowProperty overflow. Be more careful about overflow
6538 calculations, and distinguish size from memory overflow better.

6544 in the range -65535 through -1 fit in an X unsigned short.
6545 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
6546 result parameters unless successful. Rely on cons_to_unsigned
6547 to report problems with elements; the old code wasn't right anyway.

6582 * lisp.h (hash_lookup, hash_put):
6583 * minibuf.c (Ftest_completion):
6584 Use ptrdiff_t for hash table indexes, not int (which is too
6585 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

6620 exceed limits imposed by XClientMessageEvent, as well as the usual
6621 ptrdiff_t and size_t limits.
6623 * keyboard.c: Overflow, signedness and related fixes.
6624 (make_lispy_movement): Use same integer type in forward decl
6625 that is used in the definition.
6626 (read_key_sequence, keyremap_step):
6627 Change bufsize argument back to int, undoing my 2011-03-30 change.
6628 We prefer signed types, and int is wide enough here.
6629 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6630 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
6631 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
6632 length, not size_t. Use ptrdiff_t for index, not int.

6662 Prefer int to unsigned where either will do.
6663 (tiff_handler): New function, combining the cores of the
6664 old tiff_error_handler and tiff_warning_handler.
6665 This function is rewritten to use vsnprintf and thereby avoid
6666 stack buffer overflows. It uses only the features of vsnprintf
6667 that are common to both POSIX and native Microsoft.
6668 (tiff_error_handler, tiff_warning_handler): Use it.
6669 (tiff_load, gif_load, imagemagick_load_image):

6673 the integer types that MagickCropImage accepts. Don't assume
6674 Vimagemagick_render_type has a nonnegative value. Don't assume
6675 size_t fits in 'long'.
6676 (gs_load): Use printmax_t to print the widest integers possible.

6694 accurately, and prefer exact match for point under bidi.
6695 Don't advance `row' beyond the last row of the window.
6697 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
6698 into disp_prop; all users changed.
6700 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

6716 positioning on the newline at EOL of R2L text within L2R
6717 paragraph, and vice versa.
6718 (try_cursor_movement): Check continued rows, in addition to
6719 continuation rows. Fixes unwarranted scroll when point enters a
6720 continued line of R2L text within an L2R paragraph, or vice versa.
6721 (cursor_row_p): Consider the case of point being equal to
6722 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
6723 from the end of a short line to the beginning of a continued line

6751 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
6752 instead of CHAR_TO_BYTE. Fixes a crash when a completion
6753 candidate is selected by the mouse, and that candidate has a
6754 composed character under the mouse.
6756 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
6757 coordinates reported by pos-visible-in-window-p for a composed

6772 * image.c (gif_load): Don't assume that each subimage has the same
6773 dimensions as the base image. Handle disposal method that is
6774 "undefined" by the gif spec (Bug#9335).
6776 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
6778 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

6783 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
6784 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
6785 from an Org mode buffer to a Speedbar frame.
6787 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
6788 a composition, take its buffer position from IT->cmp_it.charpos.
6789 Fixes cursor positioning at the beginning of a line that begins
6790 with a composed character.
6792 2011-08-18 Eli Zaretskii <eliz@gnu.org>
6794 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
6795 character bidirectional type, use STRONG_L instead. Fixes crashes
6796 in a buffer produced by `describe-categories'.
6798 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
6799 members before the level stack, so they would be saved and
6800 restored when copying iterator state. Fixes incorrect reordering
6801 around TABs covered by display properties.
6803 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

6878 covered by an image. (Bug#9296)
6880 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
6882 * nsterm.h (ns_run_ascript): Declare.
6883 (NSAPP_DATA2_RUNASSCRIPT): Define.
6885 * nsfns.m (as_script, as_result, as_status): New static variables.
6886 (ns_run_ascript): New function.
6887 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
6888 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
6889 the event loop. Get status from as_status (Bug#7276).
6891 * nsterm.m (sendEvent): If event is NSApplicationDefined and
6892 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
6893 the event loop (Bug#7276).
6895 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
6897 * gnutls.c (QCgnutls_bootprop_priority)
6898 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
6899 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
6900 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
6901 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
6902 (QCgnutls_bootprop_verify_hostname_error)
6903 (QCgnutls_bootprop_callbacks_verify): Rename from
6904 Qgnutls_bootprop_..., all uses changed.
6906 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
6909 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
6911 * xfaces.c (Qframe_set_background_mode): Now static.
6912 * dispextern.h (Qframe_set_background_mode): Remove decl.
6914 * process.c (Fnetwork_interface_info): Declare local only if needed.
6916 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
6918 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
6919 (Fnetwork_interface_list): Allocate in increments of bytes instead
6920 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
6921 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
6923 (struct ifflag_def): notrailers is smart on OSX.
6924 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
6925 Get hardware address with getifaddrs if available.
6927 2011-08-12 Eli Zaretskii <eliz@gnu.org>
6929 * xdisp.c (iterate_out_of_display_property): xassert that
6930 IT->position is set to within IT->object's boundaries. Break from
6931 the loop as soon as EOB is reached; avoids infloops in redisplay
6932 when IT->position is set up wrongly due to some bug.
6933 Set IT->current to match the bidi iterator unconditionally.
6934 (push_display_prop): Allow GET_FROM_STRING as IT->method on
6935 entry. Force push_it to save on the stack the current
6936 buffer/string position, to be restored by pop_it. Fix flags in
6937 the iterator structure wrt the object coming from a display
6938 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
6939 properties. (Bug#9284)
6941 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
6943 * fontset.c (fontset_get_font_group): Add proper type checks.
6946 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6948 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
6949 and LC_VERSION_MIN_MACOSX.
6950 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
6951 (dump_it) [LC_FUNCTION_STARTS]: Use it.
6953 2011-08-08 Eli Zaretskii <eliz@gnu.org>
6955 * xdisp.c (forward_to_next_line_start): Allow to use the
6956 no-display-properties-and-no-overlays under bidi display.
6957 Set disp_pos in the bidi iterator to avoid searches for display
6958 properties and overlays.
6960 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
6962 * editfns.c (Fset_time_zone_rule): Document relationship with the
6965 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
6966 the font entity extracted from the cache (Bug#8109).
6968 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
6970 * composite.c (autocmp_chars): Don't reset point. That is done by
6971 restore_point_unwind (Bug#5984).
6973 2011-08-07 Juri Linkov <juri@jurta.org>
6975 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
6976 to show the arg `TIME' instead of `TIMEVAL'.
6978 2011-08-06 Eli Zaretskii <eliz@gnu.org>
6980 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
6981 display property strides EOL and includes a newline, as in
6982 longlines-mode. (Bug#9254)
6983 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
6984 word-wrap under bidirectional display. (Bug#9224)
6986 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
6987 is non-zero, even if the data buffer is NULL. Fixes a crash in
6988 vertical-motion with longlines-mode. (Bug#9254)
6990 2011-08-05 Eli Zaretskii <eliz@gnu.org>
6992 * bidi.c <bidi_cache_total_alloc>: Now static.
6993 (bidi_initialize): Initialize bidi_cache_total_alloc.
6995 * xdisp.c (display_line): Release buffer allocated for shelved bidi
6998 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
6999 amount allocated this far in `bidi_cache_total_alloc'.
7000 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7001 non-zero, only free the data buffer without restoring the cache
7002 contents. All callers changed.
7004 * dispextern.h (bidi_unshelve_cache): Update prototype.
7006 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7007 (move_it_in_display_line, move_it_to)
7008 (move_it_vertically_backward, move_it_by_lines): Replace the call
7009 to xfree to an equivalent call to bidi_unshelve_cache.
7010 (move_it_in_display_line_to): Fix logic of returning
7011 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7013 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7015 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7016 came from a string character with a `cursor' property. (Bug#9229)
7018 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7020 * Makefile.in (LIB_PTHREAD): New variable.
7021 (LIBES): Add LIB_PTHREAD (Bug#9216).
7023 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
7024 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
7026 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
7028 * regex.c (re_iswctype): Remove some redundant boolean conversions.
7030 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7032 * xterm.c (x_find_topmost_parent): New function.
7033 (x_set_frame_alpha): Find topmost parent window with
7034 x_find_topmost_parent and set the property there also (bug#9181).
7035 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
7037 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
7039 * callproc.c (Fcall_process): Avoid vfork clobbering
7040 the local vars buffer, coding_systems, current_dir.
7042 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
7044 * keymap.c (Fmake_composed_keymap): Move to subr.el.
7046 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
7048 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
7049 so that it is not optimized away.
7051 * xdisp.c (compute_display_string_pos): Remove unused local.
7053 2011-08-02 Eli Zaretskii <eliz@gnu.org>
7055 Fix slow cursor motion and scrolling in large buffers with
7056 selective display, like Org Mode buffers. (Bug#9218)
7058 * dispextern.h (struct bidi_it): New member disp_prop_p.
7060 * xdisp.c: Remove one-slot cache of display string positions.
7061 (compute_display_string_pos): Accept an additional argument
7062 DISP_PROP_P; callers changed. Scan at most 5K characters forward
7063 for a display string or property. If found, set DISP_PROP_P
7066 * bidi.c (bidi_fetch_char): Accept an additional argument
7067 DISP_PROP_P, and pass it to compute_display_string_pos.
7068 Only handle text covered by a display string if DISP_PROP_P is returned
7069 non-zero. All callers of bidi_fetch_char changed.
7071 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
7073 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
7075 2010-12-03 Don March <don@ohspite.net>
7077 * keymap.c (Fdefine_key): Fix non-prefix key error message when
7078 last character M-[char] is translated to ESC [char] (bug#7541).
7080 2011-08-02 Kenichi Handa <handa@m17n.org>
7082 * lisp.h (uniprop_table): Extern it.
7084 * chartab.c (uniprop_table): Make it non-static.
7086 2011-08-01 Eli Zaretskii <eliz@gnu.org>
7088 * xdisp.c (forward_to_next_line_start): Accept additional argument
7089 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7091 (reseat_at_next_visible_line_start): Use the bidi iterator state
7092 returned by forward_to_next_line_start to restore the state of
7093 it->bidi_it after backing up to previous newline. (Bug#9212)
7095 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
7097 * regex.c (re_comp): Protoize.
7098 (re_exec): Fix return type.
7099 (regexec): Fix type of `ret'. (Bug#9203)
7101 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7103 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7104 This is needed if max-image-size is a floating-point number.
7106 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7108 * print.c (print_object): Print empty symbol as ##.
7110 * lread.c (read1): Read ## as empty symbol.
7112 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7114 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7115 setting frame foreground color (Bug#9175).
7116 (x_set_background_color): Likewise.
7118 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7119 contents (Bug#9176).
7120 (EmacsTooltip -init): Remove bezels and add shadows to
7123 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7124 or scroll bar (Bug#8470).
7126 * nsfont.m (nsfont_open): Remove assignment to voffset and
7127 unnecessary vars hshink, expand, hd, full_height, min_height.
7128 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7130 * nsterm.h (nsfont_info): Remove voffset field.
7132 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7134 Implement strike-through and overline on NextStep (Bug#8863).
7136 * nsfont.m (nsfont_open): Use underline position provided by font,
7137 instead of hard-coded value of 2.
7138 (nsfont_draw): Call ns_draw_text_decoration instead.
7140 * nsterm.h: Add declaration for ns_draw_text_decoration.
7142 * nsterm.m (ns_draw_text_decoration): New function for drawing
7143 underline, overline, and strike-through.
7144 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
7145 ns_draw_text_decoration. Change treatment of cursor drawing to
7146 accommodate underlining, etc.
7148 2011-07-28 Eli Zaretskii <eliz@gnu.org>
7150 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
7153 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7155 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7156 Without this fix, if a signal arrives just after memory fills up,
7157 'malloc' might be invoked reentrantly.
7159 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7160 In other words, assume that every image size is allowed, on non-X
7161 hosts. This assumption is probably wrong, but it lets Emacs compile.
7163 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7165 * regex.c (re_iswctype): Convert return values to boolean.
7167 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7169 * xdisp.c (compute_display_string_pos): Don't use cached display
7170 string position if the buffer had its restriction changed.
7173 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7175 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7177 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7179 Integer signedness and overflow and related fixes. (Bug#9079)
7181 * bidi.c: Integer size and overflow fixes.
7182 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7183 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7184 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7185 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7186 (bidi_find_other_level_edge):
7187 Use ptrdiff_t instead of EMACS_INT where either will do.
7188 This works better on 32-bit hosts configured --with-wide-int.
7189 (bidi_cache_ensure_space): Check for size-calculation overflow.
7190 Use % rather than repeated addition, for better worst-case speed.
7191 Don't set bidi_cache_size until after xrealloc returns, because it
7193 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7194 (bidi_cache_ensure_space): Also check that the bidi cache size
7195 does not exceed that of the largest Lisp string or buffer. See Eli
7196 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7198 * alloc.c (__malloc_size_t): Remove.
7199 All uses replaced by size_t. See Andreas Schwab's note
7200 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7202 * image.c: Improve checking for integer overflow.
7203 (check_image_size): Assume that f is nonnull, since
7204 it is always nonnull in practice. This is one less thing to
7205 worry about when checking for integer overflow later.
7206 (x_check_image_size): New function, which checks for integer
7207 overflow issues inside X.
7208 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7209 This removes the need for a memory_full check.
7210 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7211 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7212 (xbm_read_bitmap_data): Change locals back to 'int', since
7213 their values must fit in 'int'.
7214 (xpm_load_image, png_load, tiff_load):
7215 Invoke x_create_x_image_and_pixmap earlier,
7216 to avoid much needless work if the image is too large.
7217 (tiff_load): Treat overly large images as if
7218 x_create_x_image_and_pixmap failed, not as malloc failures.
7219 (gs_load): Use x_check_image_size.
7221 * gtkutil.c: Omit integer casts.
7222 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7223 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7225 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7227 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7228 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7229 would wrongly return t on a 64-bit host.
7231 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7232 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7233 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7234 and therefore cause GCC to emit a bogus diagnostic in some cases.
7236 * image.c: Integer signedness and overflow and related fixes.
7237 This is not an exhaustive set of fixes, but it's time to
7238 record what I've got.
7239 (lookup_pixel_color, check_image_size): Remove redundant decls.
7240 (check_image_size): Don't assume that arbitrary EMACS_INT values
7241 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7242 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7243 (tiff_load, imagemagick_load_image):
7244 Check for overflow in size calculations.
7245 (x_create_x_image_and_pixmap): Remove unnecessary test for
7246 xmalloc returning NULL; that can't happen.
7247 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7248 (xpm_color_bucket): Use better integer hashing function.
7249 (xpm_cache_color): Don't possibly over-allocate memory.
7250 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7251 (gif_memory_source):
7252 Use ptrdiff_t, not int or size_t, to record sizes.
7253 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7254 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7255 either works, as we prefer signed integers.
7256 (tiff_read_from_memory, tiff_write_from_memory):
7257 Return tsize_t, not size_t, since that's what the TIFF API wants.
7258 (tiff_read_from_memory): Don't fail simply because the read would
7259 go past EOF; instead, return a short read.
7260 (tiff_load): Omit no-longer-needed casts.
7261 (Fimagemagick_types): Don't assume size fits into 'int'.
7263 Improve hashing quality when configured --with-wide-int.
7264 * fns.c (hash_string): New function, taken from sxhash_string.
7265 Do not discard information about ASCII character case; this
7266 discarding is no longer needed.
7267 (sxhash-string): Use it. Change sig to match it. Caller changed.
7268 * lisp.h: Declare it.
7269 * lread.c (hash_string): Remove, since we now use fns.c's version.
7270 The fns.c version returns a wider integer if --with-wide-int is
7271 specified, so this should help the quality of the hashing a bit.
7273 * emacs.c: Integer overflow minor fix.
7274 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7275 Define only if GNU_LINUX.
7276 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7278 * dispnew.c: Integer signedness and overflow fixes.
7279 Remove unnecessary forward decls, that were a maintenance hassle.
7280 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7282 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7283 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7284 (prepare_desired_row, line_draw_cost):
7285 Use int, not unsigned, where either works.
7286 (save_current_matrix, restore_current_matrix):
7287 Use ptrdiff_t, not size_t, where either works.
7288 (init_display): Check for overflow more accurately, and without
7289 relying on undefined behavior.
7291 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7292 Remove, replacing with the new symbols in lisp.h. All uses changed.
7293 * fileio.c (make_temp_name):
7294 * filelock.c (lock_file_1, lock_file):
7295 * xdisp.c (message_dolog):
7296 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7297 Use pMd etc. instead.
7298 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7299 replacing the pWIDE etc. symbols removed from editfns.c.
7301 * keyboard.h (num_input_events): Now uintmax_t.
7302 This is (very slightly) less likely to mess up due to wraparound.
7305 * buffer.c: Integer signedness fixes.
7306 (alloc_buffer_text, enlarge_buffer_text):
7307 Use ptrdiff_t rather than size_t when either will do, as we prefer
7310 * alloc.c: Integer signedness and overflow fixes.
7311 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7312 (__malloc_size_t): Default to size_t, not to int.
7313 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7314 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7315 Prefer ptrdiff_t to size_t when either would do, as we prefer
7317 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7318 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7319 Now const. Initialize with values that are in range even if char
7321 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7322 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7323 These functions do the right thing with sizes > 2**32.
7324 (check_depth): Now ptrdiff_t, not int.
7325 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7326 Adjust to new way of storing sizes. Check for size overflow bugs
7328 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7329 slightly wrong anyway, as it missed one instance of
7330 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7331 (refill_memory_reserve): Omit needless cast to size_t.
7332 (mark_object_loop_halt): Mark as externally visible.
7334 * xselect.c: Integer signedness and overflow fixes.
7335 (Fx_register_dnd_atom, x_handle_dnd_message):
7336 Use ptrdiff_t, not size_t, since we prefer signed.
7337 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7338 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7339 x_dnd_atoms_size and x_dnd_atoms_length.
7341 * doprnt.c: Prefer signed to unsigned when either works.
7343 * doprnt.c (doprnt):
7345 * xdisp.c (vmessage):
7346 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7347 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7348 prefer signed arithmetic to avoid comparison confusion.
7349 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7350 but is a bit tricky.
7352 Assume freestanding C89 headers, string.h, stdlib.h.
7353 * data.c, doprnt.c, floatfns.c, print.c:
7354 Include float.h unconditionally.
7355 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7356 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7357 * regex.c: Likewise for stddef.h, string.h.
7358 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7359 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7360 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7361 (STDC_HEADERS): Remove obsolete defines.
7362 * sysdep.c: Include limits.h unconditionally.
7364 Assume support for memcmp, memcpy, memmove, memset.
7365 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7366 * regex.c (memcmp, memcpy):
7367 Remove; we assume C89 now.
7369 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7370 (__malloc_safe_bcopy): Remove; no longer needed.
7372 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7373 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7374 well either way, and we prefer signed to unsigned.
7376 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7378 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7379 closes the connection while we're reading (bug#9182).
7381 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7383 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7384 are specified (Bug#9168).
7386 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7388 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7389 Found by GCC static checking and --with-wide-int on a 32-bit host.
7391 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7393 * xdisp.c (compute_display_string_pos): Fix logic of caching
7394 previous display string position. Initialize cached_prev_pos to
7395 -1. Fixes slow-down at the beginning of a buffer.
7397 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7399 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7400 for attrs[LFACE_FONTSET_INDEX].
7402 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7404 * xml.c (parse_region): Remove unused local
7405 that was recently introduced.
7407 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7409 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7410 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7412 * xdisp.c (move_it_in_display_line_to): Record the best matching
7413 position for TO_CHARPOS while scanning the line, and restore it on
7414 exit if none of the characters scanned was an exact match.
7415 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7416 when exact match is impossible due to invisible text, and the
7417 lines are truncated.
7419 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7421 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7424 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7426 Fix a significant slow-down of cursor motion with C-n, C-p,
7427 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7428 auto-repeat under bidi redisplay in fontified buffers.
7429 * xdisp.c (compute_stop_pos_backwards): New function.
7430 (next_element_from_buffer): Call compute_stop_pos_backwards to
7431 find a suitable prev_stop when we find ourselves before
7433 (reseat): Don't look for prev_stop, as that could mean a very long
7435 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7436 <cached_disp_overlay_modiff>: Cache for last found display string
7438 (compute_display_string_pos): Return the cached position if asked
7439 about the same buffer in the same area of character positions, and
7440 the buffer wasn't changed since the time the display string
7441 position was cached.
7443 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7445 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7446 is an integer, which is important for empty lines. (Bug#9149)
7448 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7450 * frame.c (Fmodify_frame_parameters): In tty case, update the
7451 default face if necessary (Bug#4238).
7453 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7455 * editfns.c (Fstring_to_char): No need to explain what a character
7456 is in the docstring (Bug#6576).
7458 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7460 * xml.c (parse_region): Make sure we always return a tree.
7462 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7464 * xml.c (parse_region): If a document contains only comments,
7467 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7469 * xml.c (make_dom): Return comments, too.
7471 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7474 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7475 and the surrounding thread.
7476 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7477 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7478 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7480 * s/openbsd.h (BROKEN_SIGIO): Define.
7481 * unexelf.c (unexec) [__OpenBSD__]:
7482 Don't update the .mdebug section of the Alpha COFF symbol table.
7484 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7486 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7489 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7491 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7492 This fixes some race conditions on the permissions of any newly
7495 * alloc.c (valid_pointer_p): Use pipe, not open.
7496 This fixes some permissions issues when debugging.
7498 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7499 If fchown fails to set both uid and gid, try to set just gid,
7500 as that is sometimes allowed. Adjust the file's mode to eliminate
7501 setuid or setgid bits that are inappropriate if fchown fails.
7503 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7505 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7506 to compare Lisp_Objects.
7507 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7508 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7509 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7511 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7513 * lread.c (read_integer): Unread even EOF character.
7514 (read1): Likewise. Properly record start position of symbol.
7516 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7517 symbol character follows.
7519 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7521 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7522 This works around a problem with the previous change to Fcopy_file.
7523 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7524 and without this change, GCC might complain about discarding
7525 fchown's return value.
7527 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7529 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7531 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7533 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7535 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7537 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7538 it's used from the C level.
7540 * process.c: Use the same condition for POLL_FOR_INPUT in both
7541 keyboard.c and process.c (bug#1858).
7543 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7545 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7546 (Fgnutls_boot): Use it.
7548 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7550 * doc.c (Fsubstitute_command_keys): Revert last change.
7552 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7554 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7555 quotes the next character, and doesn't affect other longer
7556 sequences (bug#8935).
7558 * lread.c (syms_of_lread): Clarify that is isn't only
7559 `eval-buffer' and `eval-defun' that's affected by
7560 `lexical-binding' (bug#8460).
7562 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7564 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7565 bidi redisplay when a line includes both an image and is truncated.
7567 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7569 Fix minor problems found by static checking.
7570 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7571 (elsz): Now a signed constant, not a size_t var. We prefer signed
7572 types to unsigned, to avoid integer comparison confusion. Without
7573 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7574 "cannot optimize loop, the loop counter may overflow", a symptom
7576 * indent.c (Fvertical_motion): Mark locals as initialized.
7577 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7579 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7581 * search.c (Fre_search_backward): Mention `case-fold-search' in
7582 all the re_search_* functions (bug#8138).
7584 * keyboard.c (Fopen_dribble_file): Document when the file is

7595 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
7596 (reseat_to_string): Initialize bidi_it->string.s and
7597 bidi_it->string.schars.
7598 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
7599 NULL (avoids a crash in bidi_paragraph_init).
7600 Initialize itb.string.lstring.
7601 (init_iterator): Call bidi_init_it only of a valid
7602 buffer position was specified. Initialize paragraph_embedding to
7604 (reseat_to_string): Initialize the bidi iterator.
7605 (display_string): If we need to ignore text properties of
7606 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7607 original value of -1 will not work with bidi.)
7608 (compute_display_string_pos): First arg is now struct
7609 `text_pos *'; all callers changed. Support display properties on
7611 (compute_display_string_end): Support display properties on Lisp
7613 (init_iterator, reseat_1, reseat_to_string): Initialize the
7614 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
7615 when iterating on a string not from display properties).
7616 (compute_display_string_pos, compute_display_string_end):
7617 Fix calculation of the object to scan. Fixes an error when using
7619 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7620 base_level_stop; instead, set base_level_stop to BEGV.
7621 Fixes crashes in vertical-motion.
7622 (next_element_from_buffer): Improve commentary for when
7623 the iterator is before prev_stop.
7624 (init_iterator): Initialize bidi_p from the default value of
7625 bidi-display-reordering, not from buffer-local value. Use the
7626 buffer-local value only if initializing for buffer iteration.
7627 (handle_invisible_prop): Support invisible properties on strings
7628 that are being bidi-reordered.
7629 (set_iterator_to_next): Support bidi reordering of C strings and
7631 (next_element_from_string): Support bidi reordering of Lisp
7633 (handle_stop_backwards): Support Lisp strings as well.
7634 (display_string): Support display of R2L glyph rows.
7635 Use IT_STRING_CHARPOS when displaying from a Lisp string.
7636 (init_iterator): Don't initialize it->bidi_p for strings
7638 (reseat_to_string): Initialize it->bidi_p for strings here.
7639 (next_element_from_string, next_element_from_c_string)
7640 (next_element_from_buffer): Add xassert's for correspondence
7641 between IT's object being iterated and it->bidi_it.string
7643 (face_before_or_after_it_pos): Support bidi iteration.

7645 character that is not the first one in the visual order.
7646 (get_visually_first_element): New function, refactored from common
7647 parts of next_element_from_buffer, next_element_from_string, and
7648 next_element_from_c_string.
7649 (tool_bar_lines_needed, redisplay_tool_bar)
7650 (display_menu_bar): Force left-to-right direction. Add a FIXME
7651 comment for making that be controlled by a user option.

7653 bidi iterator. Save and restore the bidi_p flag.
7654 (pop_it): Iterate out of display property for string iteration as
7656 (iterate_out_of_display_property): Support iteration over strings.
7657 (handle_single_display_spec): Set up it->bidi_it for iteration
7658 over a display string, and call bidi_init_it.

7661 iterator for displaying display or overlay strings.
7662 (forward_to_next_line_start): Don't use the shortcut if
7664 (back_to_previous_visible_line_start): If handle_display_prop
7665 pushed the iterator stack, restore the internal state of the bidi
7666 iterator by calling bidi_pop_it same number of times.
7667 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
7668 and we are bidi-iterating, don't decrement the iterator position;
7669 instead, set the first_elt flag in the bidi iterator, to produce
7671 (reseat_1): Remove redundant setting of string_from_display_prop_p.
7672 (push_display_prop): xassert that we are iterating a buffer.
7673 (push_it, pop_it): Save and restore paragraph_embedding member.
7674 (handle_single_display_spec, next_overlay_string)

7676 (push_display_prop): Set up the `unibyte' member of bidi_it.string
7677 correctly. Don't assume unibyte strings are not bidi-reordered.
7678 (compute_display_string_pos)
7679 (compute_display_string_end): Fix handling the case of C string.
7680 (push_it, pop_it): Save and restore from_disp_prop_p.
7681 (handle_single_display_spec, push_display_prop): Set the
7682 from_disp_prop_p flag.
7683 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

7685 popping after iteration over a string that came from a display
7686 property. Fix a typo in popping stretch info. Add an assertion
7687 for verifying that the iterator position is in sync with the bidi
7689 (handle_single_display_spec, get_overlay_strings_1)
7690 (push_display_prop): Fix initialization of paragraph direction for
7691 string when that of the parent object is not yet determined.

7693 iterator with IT's position. (Bug#7616)
7694 (find_row_edges): If ROW->start.pos gives position
7695 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

7704 saving a temporary copy of the iterator and restoring it back.
7705 (back_to_previous_visible_line_start, reseat_1)
7706 (init_iterator): Empty the bidi cache "stack".
7707 (move_it_in_display_line_to): If iterator ended up at
7708 EOL, but we never saw any buffer positions smaller than
7709 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
7710 motion in bidi-reordered lines.
7711 (move_it_in_display_line_to): Record prev_method and prev_pos
7712 immediately before the call to set_iterator_to_next. Fixes cursor

7718 Save and restore bidi cache.
7720 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

7729 (bidi_level_of_next_char, bidi_find_other_level_edge)
7730 (bidi_move_to_visually_next): Compare cache index with
7731 bidi_cache_start rather than with zero.
7732 (bidi_fetch_char): Accept new argument STRING; all callers
7733 changed. Support iteration over a string. Support strings with
7734 display properties. Support unibyte strings. Fix the type of
7735 `len' according to what STRING_CHAR_AND_LENGTH expects.
7736 (bidi_paragraph_init, bidi_resolve_explicit_1)
7737 (bidi_resolve_explicit, bidi_resolve_weak)

7748 initialized to valid values.
7749 (bidi_init_it): Don't initialize charpos and bytepos with invalid
7751 (bidi_level_of_next_char): Allow the sentinel "position" to pass
7752 the test for valid cached positions. Fix the logic for looking up
7753 the sentinel state in the cache. GCPRO the Lisp string we are
7755 (bidi_push_it, bidi_pop_it): New functions.
7756 (bidi_initialize): Initialize the bidi cache start stack pointer.
7757 (bidi_cache_ensure_space): New function, refactored from part of

8101 (clone_per_buffer_values): Don't assume that

8143 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8144 subseconds part to the entropy, as that's a bit more random.
8145 Prefer signed to unsigned, since the signedness doesn't matter and
8146 in general we prefer signed. When given a limit, use a
8147 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8148 latter isn't right if USE_2_TAGS_FOR_INTS.

8176 * fns.c (Frequire): Remove the mention of the .gz files, since

8193 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

8290 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
8293 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
8295 * eval.c (struct backtrace): Simplify and port the data structure.
8296 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8297 signed bit field, as this assumption is not portable and it makes
8298 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8299 "char debug_on_exit : 1" as this is not portable either; instead,
8300 use the portable "unsigned int debug_on_exit : 1". Remove unused
8301 member evalargs. Remove obsolete comments about cc bombing out.
8303 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

8338 clearly which files are directly included by each source file,
8339 and not through other includes.
8341 2011-06-27 Martin Rudalics <rudalics@gmx.at>
8343 * buffer.c (Qclone_number): Declare static and DEFSYM it.
8344 (sort_overlays, overlay_strings): When an overlay's clone number

8373 (emacs_fixed_get_preferred_height): Use min_width/height from
8374 frames size_hint to set minimum and natural (Bug#8919).
8375 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
8376 and use min_width/height from frames size_hint to set
8377 min_width/height (Bug#8919).
8379 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
8380 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

8391 * process.c (wait_reading_process_output): Bypass select if
8392 waiting for a cell while ignoring keyboard input, and input is
8393 pending. Suggested by Jan Djärv (Bug#8869).

8465 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
8467 Integer and buffer overflow fixes (Bug#8873).
8469 * print.c (printchar, strout): Check for string overflow.
8470 (PRINTPREPARE, printchar, strout):
8471 Don't set size unless allocation succeeds.
8473 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
8474 for sizes. Check for string overflow more accurately.
8475 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
8477 * macros.c: Integer and buffer overflow fixes.
8478 * keyboard.h (struct keyboard.kbd_macro_bufsize):
8479 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

8485 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
8487 * lread.c: Integer overflow fixes.
8488 (read_integer): Radix is now EMACS_INT, not int,
8489 to improve quality of diagnostics for out-of-range radices.
8490 Calculate buffer size correctly for out-of-range radices.
8491 (read1): Check for integer overflow in radices, and in
8492 read-circle numbers.
8493 (read_escape): Avoid int overflow.
8494 (Fload, openp, read_buffer_size, read1)
8495 (substitute_object_recurse, read_vector, read_list, map_obarray):

8505 Now ptrdiff_t, not int.
8506 (read1): Don't assume doc string length fits in int. Check for
8507 out-of-range doc string lengths.
8508 (read_list): Don't assume file position fits in int.
8509 (read_escape): Check for hex character overflow.
8511 2011-06-22 Leo Liu <sdl.web@gmail.com>
8513 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
8514 Move to minibuffer.el.
8516 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8518 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
8519 The following patches are for when GLYPH_DEBUG && !XASSERT.
8520 * dispextern.h (trace_redisplay_p, dump_glyph_string):
8521 * dispnew.c (flush_stdout):
8522 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
8523 Mark as externally visible.
8524 * dispnew.c (check_window_matrix_pointers): Now static.
8525 * dispnew.c (window_to_frame_vpos):
8526 * xfns.c (unwind_create_frame):
8527 * xterm.c (x_check_font): Remove unused local.
8528 * scroll.c (CHECK_BOUNDS):
8529 * xfaces.c (cache_fache): Rename local to avoid shadowing.
8530 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8531 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8532 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8533 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8535 (debug_method_add): Use va_list and vsprintf rather than relying
8536 on undefined behavior with wrong number of arguments.
8537 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8538 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8539 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8540 since we're not interested in debugging glyphs with old libraries.
8541 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8542 GCC 4.6.0's static checking.
8544 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8546 Integer overflow and signedness fixes (Bug#8873).
8547 A few related buffer overrun fixes, too.

8555 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
8556 (x_create_bitmap_from_xpm_data):
8557 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
8558 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
8560 * xfaces.c (load_pixmap):
8561 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
8562 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
8563 (.bitmaps_last, struct x_output.icon_bitmap):
8564 Use ptrdiff_t, not int, for bitmap indexes.
8565 (x_allocate_bitmap_record): Check for size overflow.
8566 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
8568 Use ptrdiff_t, not int, for overlay counts.
8569 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
8570 * editfns.c (overlays_around, get_pos_property):
8571 * textprop.c (get_char_property_and_overlay):
8572 * xdisp.c (next_overlay_change, note_mouse_highlight):
8573 * xfaces.c (face_at_buffer_position):
8574 * buffer.c (OVERLAY_COUNT_MAX): New macro.
8575 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
8576 (Fnext_overlay_change, Fprevious_overlay_change)
8577 (mouse_face_overlay_overlaps, Foverlays_in):
8578 Use ptrdiff_t, not int, for sizes.
8579 (overlays_at, overlays_in): Check for size-calculation overflow.
8581 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8583 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8584 (x_session_initialize): Do not assume string length fits in int.
8586 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8587 This is unlikely, but can occur if DPI is outlandish.
8589 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8590 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8592 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
8593 * xrdb.c (magic_file_p, search_magic_path):
8594 Omit last arg SUFFIX; it was always 0. All callers changed.
8595 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
8597 * xfont.c (xfont_match): Avoid need for strlen.
8599 * xfns.c: Don't assume strlen fits in int.
8600 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
8602 * xdisp.c (message_log_check_duplicate): Return intmax_t,
8603 not unsigned long, as we prefer signed integers. All callers changed.
8604 Detect integer overflow in repeat count.
8605 (message_dolog): Don't assume print length fits in 39 bytes.
8606 (display_mode_element): Don't assume strlen fits in int.
8608 * termcap.c: Don't assume sizes fit in int and never overflow.
8609 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
8610 (gobble_line): Check for size-calculation overflow.
8612 * minibuf.c (Fread_buffer):
8613 * lread.c (intern, intern_c_string):
8614 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
8615 Don't assume string length fits in int.
8617 * keyboard.c (parse_tool_bar_item):
8618 * gtkutil.c (style_changed_cb): Avoid need for strlen.

8624 Don't assume integer property fits in fixnum.
8625 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
8627 * filelock.c: Fix some buffer overrun and integer overflow issues.
8628 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
8629 Reformulate so as not to need the command string.
8630 Invoke gzip -cd rather than gunzip, as it's more portable.
8631 (lock_info_type, lock_file_1, lock_file):
8632 Don't assume pid_t and time_t fit in unsigned long.
8633 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8634 (current_lock_owner): Prefer signed type for sizes.
8635 Use memcpy, not strncpy, where memcpy is what is really wanted.
8636 Don't assume (via atoi) that time_t and pid_t fit in int.
8637 Check for time_t and/or pid_t out of range, e.g., via a network share.
8638 Don't alloca where an auto var works fine.
8640 * fileio.c: Fix some integer overflow issues.
8641 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8642 Don't assume string length fits in int.
8643 (directory_file_name): Don't assume string length fits in long.
8644 (make_temp_name): Don't assume pid fits in int, or that its print
8645 length is less than 20.
8647 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8649 * coding.c (make_subsidiaries): Don't assume string length fits in int.
8651 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
8653 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
8654 We prefer signed integers, even for size calculations.
8656 * emacs.c: Don't assume string length fits in 'int'.
8657 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
8658 (main): Don't invoke strlen when not needed.
8660 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

8663 * callproc.c (getenv_internal_1, getenv_internal)
8665 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8667 * lread.c (invalid_syntax): Omit length argument.
8668 All uses changed. This doesn't fix a bug, but it simplifies the
8669 code away from its former Hollerith-constant appearance, and it's
8670 one less 'int' to worry about when looking at integer-overflow issues.
8671 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8673 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8674 This didn't break anything, but it didn't help either.
8675 It's confusing to put a bogus integer in a place where the actual
8676 value does not matter.
8677 (LIST_END_P): Remove unused macro and its bogus comment.
8678 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8680 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8681 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8683 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8684 We prefer signed types, and the value cannot exceed the EMACS_INT
8685 range anyway (because otherwise the length would not be representable).
8686 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8687 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8688 This avoids a GCC warning when WIDE_EMACS_INT.
8690 * indent.c (sane_tab_width): New function.
8691 (current_column, scan_for_column, Findent_to, position_indentation)
8692 (compute_motion): Use it. This is just for clarity.
8693 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8695 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8697 * lisp.h (lint_assume): New macro.
8698 * composite.c (composition_gstring_put_cache):
8699 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8701 * editfns.c, insdel.c:
8702 Omit unnecessary forward decls, to simplify future changes.
8704 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8706 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8708 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8709 Use much-faster test for byte-length change.
8710 Don't assume string byte-length fits in 'int'.
8711 Check that character arg fits in 'int'.
8712 (mapcar1): Declare byte as byte, for clarity.
8714 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
8716 * fns.c (concat): Catch string overflow earlier.
8717 Do not rely on integer wraparound.
8719 * dispextern.h (struct it.overlay_strings_charpos)
8720 (struct it.selective): Now EMACS_INT, not int.
8721 * xdisp.c (forward_to_next_line_start)
8722 (back_to_previous_visible_line_start)
8723 (reseat_at_next_visible_line_start, next_element_from_buffer):
8724 Don't arbitrarily truncate the value of 'selective' to int.
8726 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
8728 * composite.c: Don't truncate sizes to 'int'.
8729 (composition_gstring_p, composition_reseat_it)
8730 (composition_adjust_point): Use EMACS_INT, not int.
8731 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
8732 not EMACS_UINT, for indexes.
8734 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
8736 * buffer.c: Include <verify.h>.
8737 (struct sortvec.priority, struct sortstr.priority):
8738 Now EMACS_INT, not int.
8739 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
8740 (struct sortstr.size, record_overlay_string)
8741 (struct sortstrlist.size, struct sortlist.used):
8742 Don't truncate size to int.
8743 (record_overlay_string): Check for size-calculation overflow.
8744 (init_buffer_once): Check at compile-time, not run-time.
8746 2011-06-22 Jim Meyering <meyering@redhat.com>
8748 Don't leak an XBM-image-sized buffer
8749 * image.c (xbm_load): Free the image buffer after using it.
8751 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
8754 * composite.c (find_automatic_composition): Omit needless 'return 0;'
8755 that Sun C diagnosed.
8756 * fns.c (secure_hash): Fix pointer signedness issue.
8757 * intervals.c (static_offset_intervals): New function.
8758 (offset_intervals): Use it.
8760 2011-06-21 Leo Liu <sdl.web@gmail.com>
8763 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
8766 * fns.c (secure_hash): Rename from crypto_hash_function and change
8767 the first arg to accept symbols.
8768 (Fsecure_hash): New primitive.
8769 (syms_of_fns): New symbols.
8771 2011-06-20 Deniz Dogan <deniz@dogan.se>
8773 * process.c (Fset_process_buffer): Clarify return value in
8776 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
8778 * dispnew.c (add_window_display_history): Use BVAR.
8780 * xdisp.c (debug_method_add): Use BVAR.
8781 (check_window_end, dump_glyph_matrix, dump_glyph)
8782 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
8784 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
8787 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
8788 check till after the cache is created in init_frame_faces.
8790 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
8792 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
8794 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
8796 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
8797 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
8798 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
8800 Improve buffer-overflow checking (Bug#8873).
8801 * fileio.c (Finsert_file_contents):
8802 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
8803 Remove the old (too-loose) buffer overflow checks.
8804 They weren't needed, since make_gap checks for buffer overflow.
8805 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
8806 The old code merely checked for Emacs fixnum overflow, and relied
8807 on undefined (wraparound) behavior. The new code avoids undefined
8808 behavior, and also checks for ptrdiff_t and/or size_t overflow.
8810 * editfns.c (Finsert_char): Don't dump core with very negative counts.
8811 Tune. Don't use wider integers than needed. Don't use alloca.
8812 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
8814 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
8816 * insdel.c, lisp.h (buffer_overflow): New function.
8817 (insert_from_buffer_1, replace_range, replace_range_2):
8818 * insdel.c (make_gap_larger):
8819 * editfns.c (Finsert_char):
8820 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
8822 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
8824 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
8826 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
8828 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
8829 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
8831 * fileio.c: Don't assume EMACS_INT fits in off_t.
8832 (emacs_lseek): New static function.
8833 (Finsert_file_contents, Fwrite_region): Use it.
8834 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
8836 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
8838 * fns.c: Don't overflow int when computing a list length.
8839 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
8840 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
8841 truncation on 64-bit hosts. Check for QUIT every
8842 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
8843 faster and is responsive enough.
8844 (Flength): Report an error instead of overflowing an integer.
8845 (Fsafe_length): Return a float if the value is not representable
8846 as a fixnum. This shouldn't happen except in contrived situations.
8847 (Fnthcdr, Fsort): Don't assume list length fits in int.
8848 (Fcopy_sequence): Don't assume vector length fits in int.
8850 * alloc.c: Check that resized vectors' lengths fit in fixnums.
8851 (header_size, word_size): New constants.
8852 (allocate_vectorlike): Don't check size overflow here.
8853 (allocate_vector): Check it here instead, since this is the only
8854 caller of allocate_vectorlike that could cause overflow.
8855 Check that the new vector's length is representable as a fixnum.
8857 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
8858 The previous code was bogus. For example, next_almost_prime (32)
8859 returned 39, which is undesirable as it is a multiple of 3; and
8860 next_almost_prime (24) returned 25, which is a multiple of 5 so
8861 why was the code bothering to check for multiples of 7?
8863 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
8865 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
8867 Variadic C functions now count arguments with ptrdiff_t.
8868 This partly undoes my 2011-03-30 change, which replaced int with size_t.
8869 Back then I didn't know that the Emacs coding style prefers signed int.
8870 Also, in the meantime I found a few more instances where arguments
8871 were being counted with int, which may truncate counts on 64-bit
8872 machines, or EMACS_INT, which may be unnecessarily wide.
8873 * lisp.h (struct Lisp_Subr.function.aMANY)
8874 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
8875 Arg counts are now ptrdiff_t, not size_t.
8876 All variadic functions and their callers changed accordingly.
8877 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
8878 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
8879 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
8880 * callint.c (Fcall_interactively): Check arg count for overflow,
8881 to avoid potential buffer overrun. Use signed char, not 'int',
8882 for 'varies' array, so that we needn't bother to check its size
8883 calculation for overflow.
8884 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
8885 * eval.c (apply_lambda):
8886 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
8887 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
8888 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
8890 * callint.c (Fcall_interactively): Don't use index var as event count.
8892 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
8893 * mem-limits.h (SIZE): Remove; no longer used.
8895 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
8897 Remove unnecessary casts.
8898 * xterm.c (x_term_init):
8899 * xfns.c (x_set_border_pixel):
8900 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
8901 These aren't needed now that we assume ANSI C.
8903 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
8904 It's more likely to cause problems (due to unsigned overflow)
8907 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
8909 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
8911 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
8913 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
8915 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
8917 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
8919 GLYPH_CODE_FACE returns EMACS_INT, not int.
8920 * dispextern.h (merge_faces):
8921 * xfaces.c (merge_faces):
8922 * xdisp.c (get_next_display_element, next_element_from_display_vector):
8923 Don't assume EMACS_INT fits in int.
8925 * character.h (CHAR_VALID_P): Remove unused parameter.
8926 * fontset.c, lisp.h, xdisp.c: All uses changed.
8928 * editfns.c (Ftranslate_region_internal): Omit redundant test.
8930 * fns.c (concat): Minor tuning based on overflow analysis.
8931 This doesn't fix any bugs. Use int to hold character, instead
8932 of constantly refetching from Emacs object. Use XFASTINT, not
8933 XINT, for value known to be a character. Don't bother comparing
8934 a single byte to 0400, as it's always less.
8936 * floatfns.c (Fexpt):
8937 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
8939 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
8942 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
8944 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
8945 Without this fix, on a 64-bit host (aset S 0 4294967386) would
8946 incorrectly succeed when S was a string, because 4294967386 was
8947 truncated before it was used.
8949 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
8950 Otherwise, an out-of-range integer could cause undefined behavior
8953 * composite.c: Use int, not EMACS_INT, for characters.
8954 (fill_gstring_body, composition_compute_stop_pos): Use int, not
8955 EMACS_INT, for values that are known to be in character range.
8956 This doesn't fix any bugs but is the usual style inside Emacs and
8957 may generate better code on 32-bit machines.
8959 Make sure a 64-bit char is never passed to ENCODE_CHAR.
8960 This is for reasons similar to the recent CHAR_STRING fix.
8961 * charset.c (Fencode_char): Check that character arg is actually
8962 a character. Pass an int to ENCODE_CHAR.
8963 * charset.h (ENCODE_CHAR): Verify that the character argument is no
8964 wider than 'int', as a compile-time check to prevent future regressions
8967 * character.c (char_string): Remove unnecessary casts.
8969 Make sure a 64-bit char is never passed to CHAR_STRING.
8970 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
8971 by silently ignoring the top 32 bits, allowing some values
8972 that were far too large to be valid characters.
8973 * character.h: Include <verify.h>.
8974 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
8975 arguments are no wider than unsigned, as a compile-time check
8976 to prevent future regressions in this area.
8978 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
8979 (Fsubst_char_in_region):
8981 * xdisp.c (decode_mode_spec_coding):
8982 Adjust to CHAR_STRING's new requirement.
8983 * editfns.c (Finsert_char, Fsubst_char_in_region):
8984 * fns.c (concat): Check that character args are actually
8985 characters. Without this test, these functions did the wrong
8986 thing with wildly out-of-range values on 64-bit hosts.
8988 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
8989 These casts should not be needed on 32-bit hosts, either.
8990 * keyboard.c (read_char):
8991 * lread.c (Fload): Remove casts to unsigned.
8993 * lisp.h (UNSIGNED_CMP): New macro.
8994 This fixes comparison bugs on 64-bit hosts.
8995 (ASCII_CHAR_P): Use it.
8996 * casefiddle.c (casify_object):
8997 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
8998 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
8999 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9000 * dispextern.h (FACE_FROM_ID):
9001 * keyboard.c (read_char): Use UNSIGNED_CMP.
9003 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9004 not to EMACS_INT, to avoid GCC warning.
9006 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9008 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9009 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9010 isn't needed on 32-bit machines.
9012 * buffer.c (Fgenerate_new_buffer_name):
9013 Use EMACS_INT for count, not int.
9014 (advance_to_char_boundary): Return EMACS_INT, not int.
9016 * data.c (Qcompiled_function): Now static.
9018 * window.c (window_body_lines): Now static.
9020 * image.c (gif_load): Rename local to avoid shadowing.
9022 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9023 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9024 * alloc.c (make_save_value): Integer argument is now of type
9026 (mark_object): Use ptrdiff_t, not int.
9027 * lisp.h (pD): New macro.
9028 * print.c (print_object): Use it.
9030 * alloc.c: Use EMACS_INT, not int, to count objects.
9031 (total_conses, total_markers, total_symbols, total_vector_size)
9032 (total_free_conses, total_free_markers, total_free_symbols)
9033 (total_free_floats, total_floats, total_free_intervals)
9034 (total_intervals, total_strings, total_free_strings):
9035 Now EMACS_INT, not int. All uses changed.
9036 (Fgarbage_collect): Compute overall total using a double, so that
9037 integer overflow is less likely to be a problem. Check for overflow
9038 when converting back to an integer.
9039 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9040 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9041 These were 'int' variables that could overflow on 64-bit hosts;
9042 they were never used, so remove them instead of repairing them.
9043 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9044 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9045 Previously, this ceilinged at INT_MAX, but that doesn't work on
9047 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9049 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9050 (allocate_vectorlike): Check for ptrdiff_t overflow.
9051 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9052 when a (possibly-narrower) signed value would do just as well.
9053 We prefer using signed arithmetic, to avoid comparison confusion.
9055 * alloc.c: Catch some string size overflows that we were missing.
9056 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9057 for convenience in STRING_BYTES_MAX.
9058 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9059 The definition here is exact; the one in lisp.h was approximate.
9060 (allocate_string_data): Check for string overflow. This catches
9061 some instances we weren't catching before. Also, it catches
9062 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9063 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9064 and ptrdiff_t and EMACS_INT are both 64 bits.
9066 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9067 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9068 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9070 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9072 * alloc.c (Fmake_string): Check for out-of-range init.
9074 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9076 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9078 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
9080 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
9081 xg_get_default_scrollbar_width.
9083 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
9084 (int_gtk_range_get_value): Move to the scroll bar part of the file.
9085 (style_changed_cb): Call update_theme_scrollbar_width and call
9086 x_set_scroll_bar_default_width and xg_frame_set_char_size for
9087 all frames (Bug#8505).
9088 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
9089 Call gtk_window_set_resizable if HAVE_GTK3.
9090 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9091 and height if HAVE_GTK3 (Bug#8505).
9092 (scroll_bar_width_for_theme): New variable.
9093 (update_theme_scrollbar_width): New function.
9094 (xg_get_default_scrollbar_width): Move code to
9095 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
9096 (xg_initialize): Call update_theme_scrollbar_width.
9098 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
9100 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
9102 2011-06-12 Martin Rudalics <rudalics@gmx.at>
9104 * frame.c (make_frame): Call other_buffer_safely instead of
9107 * window.c (temp_output_buffer_show): Call display_buffer with
9108 second argument Vtemp_buffer_show_specifiers and reset latter
9109 immediately after the call.
9110 (Vtemp_buffer_show_specifiers): New variable.
9111 (auto_window_vscroll_p, next_screen_context_lines)
9112 (Vscroll_preserve_screen_position): Remove leading asterisks from
9115 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
9117 Fix minor problems found by GCC 4.6.0 static checking.
9118 * buffer.c (Qclone_number): Remove for now, as it's unused.
9119 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
9120 (record_buffer): Remove unused local.
9121 * frame.c (other_visible_frames, frame_buffer_list): Now static.
9122 (set_frame_buffer_list): Remove; unused.
9123 * frame.h (other_visible_frames): Remove decl.
9124 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
9125 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
9126 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
9128 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
9129 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
9130 Define only if HAVE_GPM.
9131 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
9132 (update_hints_inhibit): Remove; never set. All uses removed.
9133 * widgetprv.h (emacsFrameClassRec): Remove decl.
9134 * window.c (delete_deletable_window): Now returns void, since it
9135 wasn't returning anything.
9136 (compare_window_configurations): Remove unused locals.
9137 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
9138 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
9139 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
9140 the same widths as pointers. This follows up on the 2011-05-06 patch.
9141 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
9142 * xterm.h: Likewise.
9143 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
9145 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
9147 * makefile.w32-in: Update dependencies.
9148 (LISP_H): Add lib/intprops.h.
9150 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
9152 * image.c (gif_load): Add animation frame delay to the metadata.
9153 (syms_of_image): Use DEFSYM. New symbol `delay'.
9155 2011-06-11 Martin Rudalics <rudalics@gmx.at>
9157 * window.c (delete_deletable_window): Re-add.
9158 (Fset_window_configuration): Rewrite to handle dead buffers and
9159 consequently deletable windows.
9160 (window_tree, Fwindow_tree): Remove. Supply functionality in
9162 (compare_window_configurations): Simplify code.
9164 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
9166 * image.c (imagemagick_load_image): Fix type mismatch.
9167 (Fimagemagick_types): Likewise.
9169 * window.h (replace_buffer_in_windows): Declare.
9171 2011-06-11 Martin Rudalics <rudalics@gmx.at>

9647 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
9648 bidirectional text is supported only in multibyte buffers.
9649 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
9650 it to initialize the frame_window_p member of struct bidi_it.
9651 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
9652 (bidi_resolve_explicit, bidi_resolve_weak)
9653 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
9654 bidi_it->nchars is non-positive.
9655 (bidi_level_of_next_char): Don't try to lookup the cache for the
9656 next/previous character if nothing is cached there yet, or if we
9657 were just reseat()'ed to a new position.
9659 * xdisp.c (set_cursor_from_row): Set start and stop points
9660 according to the row's direction when priming the loop that looks
9661 for the glyph on which to display cursor.
9662 (single_display_spec_intangible_p): Function deleted.
9663 (display_prop_intangible_p): Reimplement to call
9664 handle_display_spec instead of single_display_spec_intangible_p.
9665 Accept 3 additional arguments needed by handle_display_spec.
9666 This fixes incorrect cursor motion across display property with complex
9667 values: lists, `(when COND...)' forms, etc.
9668 (single_display_spec_string_p): Support property values that are
9669 lists with the argument STRING its top-level element.
9670 (display_prop_string_p): Fix the condition for processing a
9671 property that is a list to be consistent with handle_display_spec.
9672 (handle_display_spec): New function, refactored from the
9673 last portion of handle_display_prop.
9674 (compute_display_string_pos): Accept additional argument
9675 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
9676 value of a `display' property is a "replacing spec".
9677 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
9678 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
9679 the display property, but just return a value indicating whether
9680 the display property will replace the characters it covers.
9681 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
9682 frame_window_p members of struct bidi_it.
9683 (compute_display_string_pos, compute_display_string_end):
9685 (push_it): Accept second argument POSITION, where pop_it should
9686 jump to continue iteration.
9687 (reseat_1): Initialize bidi_it.disp_pos.
9689 * keyboard.c (adjust_point_for_property): Adjust the call to
9690 display_prop_intangible_p to its new signature.
9692 * dispextern.h (struct bidi_it): New member frame_window_p.
9693 (bidi_init_it): Update prototypes.
9694 (display_prop_intangible_p): Update prototype.
9695 (compute_display_string_pos, compute_display_string_end):
9697 (struct bidi_it): New members nchars and disp_pos. ch_len is now
9700 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
9702 Malloc failure behavior now depends on size of allocation.
9703 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
9704 * lisp.h: Change signatures accordingly.
9705 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
9706 All callers changed. (Bug#8762)
9708 * gnutls.c: Use Emacs's memory allocators.
9709 Without this change, the gnutls library would invoke malloc etc.
9710 directly, which causes problems on non-SYNC_INPUT hosts, and which
9711 runs afoul of improving memory_full behavior. (Bug#8761)
9712 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
9713 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
9714 xfree instead of the default malloc, realloc, free.
9715 (Fgnutls_boot): No need to check for memory allocation failure,
9716 since xmalloc does that for us.
9718 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
9719 * category.c (hash_get_category_set):
9720 * ccl.c (ccl_driver):
9721 * charset.c (Fdefine_charset_internal):

9732 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
9733 (Fsxhash, Fgethash, Fputhash, Fmaphash):
9734 * image.c (make_image, search_image_cache, lookup_image)
9735 (xpm_put_color_table_h):
9736 * lisp.h (struct Lisp_Hash_Table):
9737 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
9738 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
9739 for hashes and hash indexes, instead of 'unsigned' and 'int'.
9740 * alloc.c (allocate_vectorlike):
9741 Check for overflow in vector size calculations.
9742 * ccl.c (ccl_driver):
9743 Check for overflow when converting EMACS_INT to int.
9744 * fns.c, image.c: Remove unnecessary static decls that would otherwise
9745 need to be updated by these changes.
9746 * fns.c (make_hash_table, maybe_resize_hash_table):
9747 Check for integer overflow with large hash tables.
9748 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
9749 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
9750 (SXHASH_REDUCE): New macro.
9751 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
9752 Use it instead of discarding useful hash info with large hash values.
9753 (sxhash_float): New function.
9754 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
9755 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
9756 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
9757 Rewrite to use FIXNUM_BITS, as this simplifies things.
9758 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
9759 Adjust signatures to match updated version of code.
9760 (consing_since_gc): Now EMACS_INT, since a single hash table can
9761 use more than INT_MAX bytes.
9763 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
9765 Make it possible to build with GCC-4.6+ -O2 -flto.
9767 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
9769 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
9771 * minibuf.c (get_minibuffer, read_minibuf_unwind):
9772 Call minibuffer-inactive-mode.
9774 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
9776 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
9777 Update dependencies.
9779 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9781 * data.c (init_data): Remove code for UTS, this system is not
9784 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9786 Don't force ./temacs to start in terminal mode.
9788 * frame.c (make_initial_frame): Initialize faces in all cases, not
9789 only when CANNOT_DUMP is defined.
9790 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
9792 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9794 * dispnew.c (add_window_display_history): Use const for the string
9795 pointer. Remove declaration, not needed.
9797 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9799 Use 'inline', not 'INLINE'.
9800 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
9801 * alloc.c, fontset.c (INLINE): Remove.
9802 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
9803 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
9804 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
9805 * gmalloc.c (register_heapinfo): Use inline unconditionally.
9806 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
9808 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9810 Make it possible to run ./temacs.
9812 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
9813 syms_of_callproc does the same thing. Remove test for
9814 "initialized", do it in the caller.
9815 * emacs.c (main): Avoid calling set_initial_environment when dumping.
9817 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
9819 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
9820 (read_minibuf): Use get_minibuffer.
9821 (syms_of_minibuf): Use DEFSYM.
9822 (Qmetadata): New var.
9823 * data.c (Qbuffer): Don't make it static.
9824 (syms_of_data): Use DEFSYM.
9826 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9828 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
9829 (CCL_CODE_MIN): New macro.
9831 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
9833 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
9835 * eval.c (Qdebug): Now static.
9836 * lisp.h (Qdebug): Remove decl. This reverts a part of the
9837 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
9838 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
9840 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9842 * image.c: Various fixes to ImageMagick code comments.
9843 (Fimagemagick_types): Doc fix.
9845 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
9847 Minor fixes prompted by GCC 4.6.0 warnings.
9849 * xselect.c (converted_selections, conversion_fail_tag): Now static.
9851 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
9852 (x_clipboard_manager_save_all): Move extern decl to ...
9853 * xterm.h: ... here, so that it can be checked for consistency.
9855 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9857 * xselect.c (x_clipboard_manager_save_frame)
9858 (x_clipboard_manager_save_all): New functions.
9859 (Fx_clipboard_manager_save): Lisp function deleted.
9861 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
9862 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
9864 * xterm.h: Update prototype.
9866 2011-05-28 William Xu <william.xwl@gmail.com>
9868 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
9871 2011-05-28 Jim Meyering <meyering@redhat.com>
9873 Avoid a sign-extension bug in crypto_hash_function.
9874 * fns.c (to_uchar): Define.
9875 (crypto_hash_function): Use it to convert some newly-signed
9876 variables to unsigned, to avoid sign-extension bugs. For example,
9877 without this change, (md5 "truc") would evaluate to
9878 45723a2aff78ff4fff7fff1114760e62 rather than the expected
9879 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
9880 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
9882 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9884 Integer overflow fixes.
9886 * dbusbind.c: Serial number integer overflow fixes.
9887 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
9888 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
9889 to hold a serial number that is too large for a fixnum.
9890 (Fdbus_method_return_internal, Fdbus_method_error_internal):
9891 Check for serial numbers out of range. Decode any serial number
9892 that was so large that it became a float. (Bug#8722)
9894 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
9895 (Fdbus_call_method, Fdbus_call_method_asynchronously):
9896 Use XFASTINT rather than XUINT when numbers are nonnegative.
9897 (xd_append_arg, Fdbus_method_return_internal):
9898 (Fdbus_method_error_internal): Likewise. Also, for unsigned
9899 arguments, check that Lisp number is nonnegative, rather than
9900 silently wrapping negative numbers around. (Bug#8722)
9901 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
9904 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
9906 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
9908 ccl: Add integer overflow checks.
9909 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
9910 (IN_INT_RANGE): New macros.
9911 (ccl_driver): Use them to check for integer overflow when
9912 decoding a CCL program. Many of the new checks are whether XINT (x)
9913 fits in int; it doesn't always, on 64-bit hosts. The new version
9914 doesn't catch all possible integer overflows, but it's an
9915 improvement. (Bug#8719)
9917 * alloc.c (make_event_array): Use XINT, not XUINT.
9918 There's no need for unsigned here.
9920 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
9921 This follows up to the 2011-05-06 change that substituted uintptr_t
9922 for EMACS_INT. This case wasn't caught back then.
9924 Rework Fformat to avoid integer overflow issues.
9925 * editfns.c: Include <float.h> unconditionally, as it's everywhere
9926 now (part of C89). Include <verify.h>.
9927 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
9928 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
9929 (Fformat): Avoid the prepass trying to compute sizes; it was only
9930 approximate and thus did not catch overflow reliably. Instead, walk
9931 through the format just once, formatting and computing sizes as we go,
9932 checking for integer overflow at every step, and allocating a larger
9933 buffer as needed. Keep track separately whether the format is
9934 multibyte. Keep only the most-recently calculated precision, rather
9935 than them all. Record whether each argument has been converted to
9936 string. Use EMACS_INT, not int, for byte and char and arg counts.
9937 Support field widths and precisions larger than INT_MAX. Avoid
9938 sprintf's undefined behavior with conversion specifications such as %#d
9939 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
9940 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
9941 formatting out-of-range floating point numbers with int
9944 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
9946 * data.c: Avoid integer truncation in expressions involving floats.
9947 * data.c: Include <intprops.h>.
9948 (arith_driver): When there's an integer overflow in an expression
9949 involving floating point, convert the integers to floating point
9950 so that the resulting value does not suffer from catastrophic
9951 integer truncation. For example, on a 64-bit host (* 4
9952 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
9953 Do not rely on undefined behavior after integer overflow.
9955 merge count_size_as_multibyte, parse_str_to_multibyte
9956 * character.c, character.h (count_size_as_multibyte):
9957 Rename from parse_str_to_multibyte; all uses changed.
9958 Check for integer overflow.
9959 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
9960 since it's now a duplicate of the other. This is more of
9961 a character than a buffer op, so better that it's in character.c.
9962 * fns.c, print.c: Adjust to above changes.
9964 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
9966 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
9968 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9970 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9971 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
9972 (x_clipboard_manager_save): Now static.
9973 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
9975 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9976 (crypto_hash_function): Now static.
9977 Fix pointer signedness problems. Avoid unnecessary initializations.
9979 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
9981 * termhooks.h (Vselection_alist): Make it terminal-local.
9983 * terminal.c (create_terminal): Initialize it.
9985 * xselect.c: Support for clipboard managers.
9986 (Vselection_alist): Move to termhooks.h as terminal-local var.

9991 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
9992 (x_own_selection, x_get_local_selection, x_convert_selection):
9993 New arg, specifying work frame. Use terminal-local Vselection_alist.
9994 (some_frame_on_display): Delete unused function.
9995 (Fx_own_selection_internal, Fx_get_selection_internal)
9996 (Fx_disown_selection_internal, Fx_selection_owner_p)
9997 (Fx_selection_exists_p): New optional frame arg.
9998 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
9999 (x_handle_selection_clear): Don't treat other terminals with the
10000 same keyboard specially. Use the terminal-local Vselection_alist.
10001 (x_clear_frame_selections): Use Frun_hook_with_args.
10003 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10005 * xterm.h: Add support for those atoms.
10007 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10009 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10010 (converted_selections, conversion_fail_tag): New global variables.
10011 (x_selection_request_lisp_error): Free the above.
10012 (x_get_local_selection): Remove unnecessary code.
10013 (x_reply_selection_request): Args changed; handle arbitrary array
10014 of converted selections stored in converted_selections.
10015 Separate the XChangeProperty and SelectionNotify steps.
10016 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10017 (x_convert_selection): New function.
10018 (x_handle_selection_event): Simplify.
10019 (x_get_foreign_selection): Don't ignore incoming requests while
10020 waiting for an answer; this will fail when we implement
10021 SAVE_TARGETS, and seems unnecessary anyway.
10022 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10023 (Vx_sent_selection_functions): Doc fix.
10025 2011-05-26 Leo Liu <sdl.web@gmail.com>
10027 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10029 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10031 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10033 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10034 for fringe update if it has periodic bitmap.
10035 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10036 and fringe_bitmap_periodic_p.
10038 * fringe.c (get_fringe_bitmap_data): New function.
10039 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10040 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10041 row. Mark glyph row for fringe update if periodicity changed.
10043 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10044 for fringe update unless it has periodic bitmap.
10046 2011-05-25 Kenichi Handa <handa@m17n.org>
10048 * xdisp.c (get_next_display_element): Set correct it->face_id for

10064 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10065 Remove macros that are defined and never used.
10066 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10068 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10070 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10071 (Fx_get_selection_internal): Minor cleanup.
10072 (Fx_own_selection_internal): Rename arguments for consistency with
10075 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>

10092 and add some more files.
10094 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10096 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10097 report_file_error introduced by the change from 2011-05-07.
10099 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10101 * systime.h (Time): Define only if emacs is defined.
10102 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10103 where the include path doesn't have X11/X.h by default. See
10104 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10106 2011-05-20 Kenichi Handa <handa@m17n.org>
10108 * composite.c (find_automatic_composition): Fix previous change.
10110 2011-05-20 Glenn Morris <rgm@gnu.org>
10112 * lisp.mk: New file, split from Makefile.in.
10113 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10114 (shortlisp): Remove.
10115 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10117 2011-05-19 Glenn Morris <rgm@gnu.org>
10119 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10120 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10121 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10122 (lisp): Set the order to that of loadup.el.
10123 (shortlisp): Make it a copy of $lisp.
10124 (SOME_MACHINE_LISP): Remove.
10125 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10126 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10128 2011-05-18 Kenichi Handa <handa@m17n.org>
10130 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10131 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10132 (find_automatic_composition): Mostly rewrite for efficiency.
10134 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10136 * makefile.w32-in: Update dependencies.
10138 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10140 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10141 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10143 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10145 Fix some integer overflow issues, such as string length overflow.
10147 * insdel.c (count_size_as_multibyte): Check for string overflow.
10149 * character.c (lisp_string_width): Check for string overflow.
10150 Use EMACS_INT, not int, for string indexes and lengths; in
10151 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10152 the resulting string length overflows an EMACS_INT; instead,
10153 report a string overflow if no precision given. When checking for
10154 precision exhaustion, use a check that cannot possibly have
10155 integer overflow. (Bug#8675)
10156 * character.h (lisp_string_width): Adjust to new signature.
10158 * alloc.c (string_overflow): New function.
10159 (Fmake_string): Use it. This doesn't change behavior, but saves
10160 a few bytes and will simplify future changes.
10161 * character.c (string_escape_byte8): Likewise.
10162 * lisp.h (string_overflow): New decl.
10164 Fixups, following up to the user-interface timestamp change.
10165 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10166 for UI timestamps, instead of unsigned long.
10167 * msdos.c (mouse_get_pos): Likewise.
10168 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10169 * w32gui.h (Time): Define by including "systime.h" rather than by
10170 declaring it ourselves. (Bug#8664)
10172 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10173 * image.c (clear_image_cache): Likewise.
10175 * term.c (term_mouse_position): Don't assume time_t wraparound.
10177 Be more systematic about user-interface timestamps.
10178 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10179 and sometimes 'EMACS_UINT', to represent these timestamps.
10180 This change causes it to use 'Time' uniformly, as that's what X uses.
10181 This makes the code easier to follow, and makes it easier to catch
10182 integer overflow bugs such as Bug#8664.
10183 * frame.c (Fmouse_position, Fmouse_pixel_position):
10184 Use Time, not unsigned long, for user-interface timestamps.
10185 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10186 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10187 * keyboard.h (last_event_timestamp): Likewise.
10188 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10189 * menu.h (xmenu_show): Likewise.
10190 * term.c (term_mouse_position): Likewise.
10191 * termhooks.h (struct input_event.timestamp): Likewise.
10192 (struct terminal.mouse_position_hook): Likewise.
10193 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10194 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10195 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10196 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10197 what it was before.
10198 * menu.h, termhooks.h: Include "systime.h", for Time.
10200 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10201 Don't assume that the difference between two unsigned long values
10202 can fit into an integer. At this point, we know button_down_time
10203 <= event->timestamp, so the difference must be nonnegative, so
10204 there's no need to cast the result if double-click-time is
10205 nonnegative, as it should be; check that it's nonnegative, just in
10206 case. This bug is triggered when events are more than 2**31 ms
10207 apart (about 25 days). (Bug#8664)
10209 * xselect.c (last_event_timestamp): Remove duplicate decl.
10210 (x_own_selection): Remove needless cast to unsigned long.
10212 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10213 that always fit in int. Use a sentinel instead of a counter, to
10214 avoid a temp and to allay GCC's concerns about possible int overflow.
10215 * frame.h (struct frame): Use int for menu_bar_items_used
10216 instead of EMACS_INT, since it always fits in int.
10218 * menu.c (grow_menu_items): Check for int overflow.
10220 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10222 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10223 Before, the code was not consistent. These values cannot exceed
10224 2**31 - 1 so there's no need to make them unsigned.
10225 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10226 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10227 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10229 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10231 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10232 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10233 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10234 presumably because the widths might not match.
10236 * window.c (size_window): Avoid needless test at loop start.
10238 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10240 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10242 2011-05-12 Drew Adams <drew.adams@oracle.com>
10244 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10246 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10248 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10249 `width' to `bar_area_x' and `bar_area_width', respectively.
10250 (x_scroll_run): Take account of fringe background extension.
10252 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10253 Rename local vars `left' and `width' to `bar_area_x' and
10254 `bar_area_width', respectively.
10255 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10256 background extension.
10258 2011-05-10 Jim Meyering <meyering@redhat.com>
10260 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10262 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10264 * image.c (Finit_image_library): Return t for built-in image types,
10265 like pbm and xbm. (Bug#8640)
10267 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10269 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10271 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10273 * w32console.c (Fset_screen_color): Doc fix.
10274 (Fget_screen_color): New function.
10275 (syms_of_ntterm): Defsubr it.
10277 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10278 unlink the temporary file if Fcall_process didn't create it in the
10280 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10281 child process will be redirected to a file specified with `:file'.
10282 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10283 cue to call_process_cleanup not to close that handle.
10285 2011-05-07 Ben Key <bkey76@gmail.com>
10287 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10288 one of two shell specific rules, either bootstrap-temacs-CMD or
10289 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10290 to the previous implementation of the bootstrap-temacs rule.
10291 The bootstrap-temacs-CMD rule is similar to the previous
10292 implementation of the bootstrap-temacs rule except that it
10293 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10296 These changes, along with some changes to nt/configure.bat,
10297 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10298 earlier fix to add support for --cflags and --ldflags options
10299 that include quotes so that it works whether make uses cmd or
10302 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10304 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10305 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10307 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10308 a string. Handle both cases.
10309 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10310 (Fdbus_register_method): Use Qinvalid_function.
10312 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10314 * makefile.w32-in: Update dependencies.
10315 (LISP_H): Add inttypes.h and stdin.h.
10316 (PROCESS_H): Add unistd.h.
10318 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10320 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10321 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10323 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10325 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10327 * term.c (vfatal): Remove stray call to va_end.
10328 It's not needed and the C Standard doesn't allow it here anyway.
10330 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10331 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10333 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10336 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10338 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10340 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10342 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10344 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10346 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10347 * charset.c (Fdefine_charset_internal): Don't initialize
10348 charset.code_space[15]. The value was garbage, on hosts with
10349 32-bit int (Bug#8600).
10351 * lread.c (read_integer): Be more consistent with string-to-number.
10352 Use string_to_number to do the actual conversion; this avoids
10353 rounding errors and fixes some other screwups. Without this fix,
10354 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10355 (digit_to_number): Move earlier, for benefit of read_integer.
10356 Return -1 if the digit is out of range for the base, -2 if it is
10357 not a digit in any supported base. (Bug#8602)
10359 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10361 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10362 to match comment at start of function. This also removes a
10363 GCC warning about overflow in a 32+64-bit port.
10365 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10367 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10368 Reported by Stefan Monnier in
10369 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10370 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10371 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10373 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10374 (EMACS_UINTPTR): Likewise, with uintptr_t.
10376 * lisp.h: Prefer 64-bit EMACS_INT if available.
10377 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10378 on 32-bit hosts that have 64-bit int, so that they can access
10380 However, temporarily disable this change unless the temporary
10381 symbol WIDE_EMACS_INT is defined.
10383 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10385 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10386 This removes an assumption that EMACS_INT and long are the same
10387 width as pointers. The assumption is true for Emacs porting targets
10388 now, but we want to make other targets possible.
10389 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10390 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10391 In the rest of the code, change types of integers that hold casted
10392 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10393 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10394 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10395 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10396 No need to cast type when ORing.
10397 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10398 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10399 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10400 assume EMACS_INT is the same width as char *.
10401 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10402 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10403 Remove no-longer-needed casts.
10404 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10405 (xg_tool_bar_help_callback, xg_make_tool_item):
10406 Use EMACS_INTPTR to hold an integer
10407 that will be cast to void *; this can avoid a GCC warning
10408 if EMACS_INT is not the same width as void *.
10409 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10410 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10411 (current_message_1, set_message_1):
10412 Use a local to convert to proper width without a cast.
10413 * xmenu.c (dialog_selection_callback): Likewise.
10415 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10416 Also, don't assume VALBITS / RAND_BITS is less than 5,
10417 and don't rely on undefined behavior when shifting a 1 left into
10419 * lisp.h (get_random): Change signature to match.
10421 * lread.c (hash_string): Use size_t, not int, for hash computation.
10422 Normally we prefer signed values; but hashing is special, because
10423 it's better to use unsigned division on hash table sizes so that
10424 the remainder is nonnegative. Also, size_t is the natural width
10425 for hashing into memory. The previous code used 'int', which doesn't
10426 retain enough info to hash well into very large tables.
10427 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10429 * dbusbind.c: Don't possibly lose pointer info when converting.
10430 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10431 Use XPNTR rather than XHASH, so that the high-order bits of
10432 the pointer aren't lost when converting through void *.
10434 * eval.c (Fautoload): Don't double-shift a pointer.
10436 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10438 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10440 * gnutls.c (DEF_GNUTLS_FN):
10441 * image.c (DEF_IMGLIB_FN): Make function pointers static.
10443 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
10445 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
10448 2011-05-05 Eli Zaretskii <eliz@gnu.org>
10450 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
10451 New version that can reserve upto 2GB of heap space.
10453 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
10455 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
10457 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
10459 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
10460 `gnutls_certificate_set_x509_key_file'.
10462 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
10464 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
10465 Update dependencies.
10467 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10469 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
10470 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
10471 Remove unused parameter `fildes'.
10472 * process.c (read_process_output, send_process): Don't pass it.
10474 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10476 Fix previous change: the library cache is defined in w32.c.
10477 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
10478 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
10480 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10482 Implement dynamic loading of GnuTLS on Windows.
10484 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
10485 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
10486 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10489 * gnutls.c (Qgnutls_dll): Define.
10490 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
10491 (gnutls_*): Declare function pointers.
10492 (init_gnutls_functions): New function to initialize function pointers.
10493 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
10494 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
10495 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10496 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
10497 (emacs_gnutls_write, emacs_gnutls_read)
10498 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
10499 (Fgnutls_available_p): New function.
10500 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
10501 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
10502 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
10504 * image.c: Include w32.h.
10505 (Vimage_type_cache): Delete.
10506 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
10507 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
10508 (w32_delayed_load): Move to w32.c.
10510 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.

10519 * process.c: Include lisp.h before w32.h, not after.
10520 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10521 instead of gnutls_record_check_pending.

10573 rather than `XVECTOR (FOO)->size'.
10575 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10576 inttypes.h, as a gnulib replacement is used if it not available in

10591 charbuf for the composition carryover bytes.
10593 2011-04-21 Eli Zaretskii <eliz@gnu.org>

10598 %llo or %llx format is passed. (Bug#8545)
10600 * window.c (window_scroll_line_based): Use a marker instead of
10601 simple variables to record original value of point. (Bug#7952)
10603 * doprnt.c (doprnt): Fix the case where a multibyte sequence
10604 produced by %s or %c overflows available buffer space. (Bug#8545)
10606 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10608 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
10609 (SIZE_MAX): Move defn after all includes, as they might #define it.
10611 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10613 * w32.c (init_environment): Warn about defaulting HOME to C:\.
10615 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10617 * keyboard.c (Qdelayed_warnings_hook): Define.
10618 (command_loop_1): Run `delayed-warnings-hook'
10619 if Vdelayed_warnings_list is non-nil.
10620 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
10621 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
10623 2011-04-28 Eli Zaretskii <eliz@gnu.org>
10625 * doprnt.c (doprnt): Don't return value smaller than the buffer
10626 size if the message was truncated. (Bug#8545).
10628 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10630 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

10633 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10635 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
10637 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
10639 * makefile.w32-in: Update dependencies.
10641 2011-04-27 Eli Zaretskii <eliz@gnu.org>
10643 Improve `doprnt' and its usage. (Bug#8545)
10644 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
10645 `format_end'. Remove support for %l as a conversion specifier.
10646 Don't use xrealloc. Improve diagnostics when the %l size modifier
10647 is used. Update the commentary.
10649 * eval.c (verror): Simplify calculation of size_t.
10651 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
10654 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
10656 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10659 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10661 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10662 This makes this file independent of the recent pseudovector change.
10664 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
10666 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10668 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10669 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10670 Remove unused local.
10671 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10673 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
10674 GCC 4.6.0 optimizes based on type-based alias analysis.
10675 For example, if b is of type struct buffer * and v of type struct
10676 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10677 != &v->size, and therefore "v->size = 1; b->size = 2; return
10678 v->size;" must therefore return 1. This assumption is incorrect
10679 for Emacs, since it type-puns struct Lisp_Vector * with many other
10680 types. To fix this problem, this patch adds a new type struct
10681 vectorlike_header that documents the constraints on layout of vectors
10682 and pseudovectors, and helps optimizing compilers not get fooled
10683 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
10684 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10685 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10687 (XSETPVECTYPE): Rewrite in terms of new macro.
10688 (XSETPVECTYPESIZE): New macro, specifying both type and size.
10689 This is a bit clearer, and further avoids the possibility of
10690 undesirable aliasing.
10691 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10692 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10693 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10694 since Lisp_Subr is a special case (no "next" field).
10695 (ASIZE): Now uses header.size rather than size.
10696 All previous uses of XVECTOR (foo)->size replaced to use this macro,
10697 to avoid the hassle of writing XVECTOR (foo)->header.size.
10698 (struct vectorlike_header): New type.
10699 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10700 object, to help avoid aliasing.
10701 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10702 (SUBRP): Likewise, since Lisp_Subr is a special case.
10703 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10704 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10705 (struct Lisp_Hash_Table): Combine first two members into a single
10706 struct vectorlike_header member. All uses of "size" and "next" members
10707 changed to be "header.size" and "header.next".
10708 * buffer.h (struct buffer): Likewise.
10709 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
10710 * frame.h (struct frame): Likewise.
10711 * process.h (struct Lisp_Process): Likewise.
10712 * termhooks.h (struct terminal): Likewise.
10713 * window.c (struct save_window_data, struct saved_window): Likewise.
10714 * window.h (struct window): Likewise.
10715 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
10716 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
10717 * buffer.c (init_buffer_once): Likewise.
10718 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
10720 * process.c (Fformat_network_address): Use local var for size,
10723 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
10725 Make the Lisp reader and string-to-float more consistent (Bug#8525)
10726 * data.c (atof): Remove decl; no longer used or needed.
10727 (digit_to_number): Move to lread.c.
10728 (Fstring_to_number): Use new string_to_number function, to be
10729 consistent with how the Lisp reader treats infinities and NaNs.
10730 Do not assume that floating-point numbers represent EMACS_INT
10731 without losing information; this is not true on most 64-bit hosts.
10732 Avoid double-rounding errors, by insisting on integers when
10733 parsing non-base-10 numbers, as the documentation specifies.
10734 * lisp.h (string_to_number): New decl, replacing ...
10735 (isfloat_string): Remove.
10736 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
10737 (read1): Do not accept +. and -. as integers; this
10738 appears to have been a coding error. Similarly, do not accept
10739 strings like +-1e0 as floating point numbers. Do not report
10740 overflow for integer overflows unless the base is not 10 which
10741 means we have no simple and reliable way to continue.
10742 Break out the floating-point parsing into a new
10743 function string_to_number, so that Fstring_to_number parses
10744 floating point numbers consistently with the Lisp reader.
10745 (digit_to_number): Move here from data.c. Make it static inline.
10746 (E_CHAR, EXP_INT): Remove, replacing with ...
10747 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
10748 (string_to_number): New function, replacing isfloat_string.
10749 This function checks for valid syntax and produces the resulting
10750 Lisp float number too. Rework it so that string-to-number
10751 no longer mishandles examples like "1.0e+". Use strtoumax,
10752 so that overflow for non-base-10 numbers is reported only when
10753 there's no portable and simple way to convert to floating point.
10755 * textprop.c (set_text_properties_1): Rewrite for clarity,
10756 and to avoid GCC warning about integer overflow.
10758 * intervals.h (struct interval): Use EMACS_INT for members
10759 where EMACS_UINT might cause problems. See
10760 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
10761 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
10762 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
10764 (offset_intervals): Tell GCC not to worry about length overflow
10765 when negating a negative length.
10767 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
10768 (overrun_check_free): Likewise.
10770 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
10771 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
10774 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10775 (gnutls_make_error): Rename local to avoid shadowing.
10776 (gnutls_emacs_global_deinit): ifdef out; not used.
10777 (Fgnutls_boot): Use const for pointer to readonly storage.
10778 Comment out unused local. Fix pointer signedness problems.
10780 * lread.c (openp): Don't stuff size_t into an 'int'.
10781 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
10782 about possible signed overflow.
10784 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10785 (GDK_KEY_g): Don't define if already defined.
10786 (xg_prepare_tooltip): Avoid pointer signedness problem.
10787 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
10789 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
10790 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
10792 * xfns.c (Fx_window_property): Simplify a bit,
10793 to make a bit faster and to avoid GCC 4.6.0 warning.
10794 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
10796 * fns.c (internal_equal): Don't assume size_t fits in int.
10798 * alloc.c (compact_small_strings): Tighten assertion a little.
10800 Replace pEd with more-general pI, and fix some printf arg casts.
10801 * lisp.h (pI): New macro, generalizing old pEd macro to other
10802 conversion specifiers. For example, use "...%"pI"d..." rather
10803 than "...%"pEd"...".
10804 (pEd): Remove. All uses replaced with similar uses of pI.
10805 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
10806 * alloc.c (check_pure_size): Don't overflow by converting size to int.
10807 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
10808 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
10809 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
10810 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
10811 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
10813 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
10814 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
10815 * print.c (safe_debug_print, print_object): Likewise.
10816 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
10818 Use pI instead of if-then-else-abort. Use %p to avoid casts,
10819 avoiding the 0 flag, which is not portable.
10820 * process.c (Fmake_network_process): Use pI to avoid cast.
10821 * region-cache.c (pp_cache): Likewise.
10822 * xdisp.c (decode_mode_spec): Likewise.
10823 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
10824 behavior on 64-bit hosts with printf arg.
10825 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
10826 (x_stop_queuing_selection_requests): Likewise.
10827 (x_get_window_property): Don't truncate byte count to an 'int'
10830 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
10831 here, since it parses constructs like leading '-' and spaces,
10832 which are not wanted; and it overflows with large numbers.
10833 Instead, simply match F[0-9]+, which is what is wanted anyway.
10835 * alloc.c: Remove unportable assumptions about struct layout.
10836 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
10837 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
10838 (allocate_vectorlike, make_pure_vector): Use the new macros,
10839 plus offsetof, to remove unportable assumptions about struct layout.
10840 These assumptions hold on all porting targets that I know of, but
10841 they are not guaranteed, they're easy to remove, and removing them
10842 makes further changes easier.
10844 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
10845 This doesn't fix a bug but makes the code clearer.
10846 (string_overrun_cookie): Now const. Use initializers that
10847 don't formally overflow signed char, to avoid warnings.
10848 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
10849 can cause Emacs to crash when string overrun checking is enabled.
10850 (allocate_buffer): Don't assume sizeof (struct buffer) is a
10851 multiple of sizeof (EMACS_INT); it need not be, if
10852 alignof(EMACS_INT) < sizeof (EMACS_INT).
10853 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
10855 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

10870 (handle_user_signal): Break into debugger when debug-on-event
10871 matches the current signal symbol.
10873 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
10875 * alloc.c (check_sblock, check_string_bytes)
10876 (check_string_free_list): Convert to standard C.
10878 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
10880 * w32.c (emacs_gnutls_push): Fix typo.
10882 2011-04-25 Eli Zaretskii <eliz@gnu.org>
10884 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
10885 "cast to pointer from integer of different size".
10887 Improve doprnt and its use in verror. (Bug#8545)
10888 * doprnt.c (doprnt): Document the set of format control sequences
10889 supported by the function. Use SAFE_ALLOCA instead of always
10892 * eval.c (verror): Don't limit the buffer size at size_max-1, that
10893 is one byte too soon. Don't use xrealloc; instead xfree and
10896 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
10898 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
10901 * gnutls.c: Renamed global_initialized to
10902 gnutls_global_initialized. Added internals for the
10903 :verify-hostname-error, :verify-error, and :verify-flags
10904 parameters of `gnutls-boot' and documented those parameters in the
10905 docstring. Start callback support.
10906 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
10907 unless a fatal error occurred. Call gnutls_alert_send_appropriate
10908 on error. Return error code.
10909 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
10910 (emacs_gnutls_read): Likewise.
10911 (Fgnutls_boot): Return handshake error code.
10912 (emacs_gnutls_handle_error): New function.
10913 (wsaerror_to_errno): Likewise.

10916 (emacs_gnutls_push): Likewise.
10918 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
10919 (emacs_gnutls_push): Likewise.
10921 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
10923 * process.c (wait_reading_process_output): Check if GnuTLS
10924 buffered some data internally if no FDs are set for TLS
10927 * makefile.w32-in (OBJ2): Add gnutls.$(O).
10928 (LIBS): Link to USER_LIBS.

10934 display_replaced_before_p argument into display_replaced_p, to
10935 make it consistent with the commentary. Fix typos in the
10938 * textprop.c (syms_of_textprop): Remove dead code.

11236 * process.c (send_process): Adjust to the new signatures of
11237 emacs_write and emacs_gnutls_write. Do not attempt to store

11430 * font.c (font_close_object): Now static.
11431 * font.h (font_close_object): Remove.
11432 * fontset.c (FONTSET_OBJLIST): Remove.
11433 (free_realized_fontset) #if-0 the body, which does nothing.
11434 (face_suitable_for_char_p): #if-0, as it's never called.
11435 * fontset.h (face_suitable_for_char_p): Remove decl.
11436 * xfaces.c (face_at_string_position):
11437 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
11438 since 0 is always ASCII.
11440 * fns.c (weak_hash_tables): Now static.
11442 * fileio.c: Make symbols static if they're not exported.

11461 * editfns.c, lisp.h (get_operating_system_release): Remove.
11462 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
11463 worth the hassle of breaking this out.
11465 * xterm.c: Make symbols static if they're not exported.
11466 (x_raise_frame, x_lower_frame, x_wm_set_window_state):
11467 (x_wm_set_icon_pixmap, x_initialize, XTread_socket_fake_io_error):

11569 * buffer.c (buffer_count): Remove unused var.

11578 * atimer.h (run_all_atimers): Remove; not exported.
11580 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
11581 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
11582 was inaccessible from Lisp.
11583 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
11584 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
11586 alloc.c: Import and export fewer symbols, and remove unused items.
11587 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
11589 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
11590 it's not optimized away by whole-program optimization.
11591 (message_enable_multibyte, free_misc): Remove.
11592 (catchlist, handlerlist, mark_backtrace):
11593 Declare only if BYTE_MARK_STACK.

11602 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
11603 (mark_backtrace): Define only if BYTE_MARK_STACK.
11604 * xdisp.c (message_enable_multibyte): Now static.
11606 Declare Lisp_Object Q* variables to be 'static' if not exported.
11607 This makes it easier for human readers (and static analyzers)
11608 to see whether these variables are used from other modules.
11609 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
11610 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

11619 Remove decls of unexported vars.
11620 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
11622 * lisp.h (DEFINE_FUNC): Make sname 'static'.
11624 Make Emacs functions such as Fatom 'static' by default.
11625 This makes it easier for human readers (and static analyzers)
11626 to see whether these functions can be called from other modules.
11627 DEFUN now defines a static function. To make the function external
11628 so that it can be used in other C modules, use the new macro DEFUE.
11629 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
11630 (Finit_image_library):
11631 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
11632 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
11633 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
11634 Remove decls, since these functions are now static.
11635 (Funintern, Fget_internal_run_time): New decls, since these functions
11636 were already external.
11638 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
11639 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

11645 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
11646 Mark functions with DEFUE instead of DEFUN,
11647 if they are used in other modules.
11648 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
11649 decls for now-static functions.
11650 * buffer.h (Fdelete_overlay): Remove decl.
11651 * callproc.c (Fgetenv_internal): Mark as internal.
11652 * composite.c (Fremove_list_of_text_properties): Remove decl.

11658 (Funintern): Remove extern decl; now in .h file where it belongs.
11659 * fileio.c (Fmake_symbolic_link): New forward static decl.
11660 * image.c (Finit_image_library): New forward static decl.
11661 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
11662 * intervals.h (Fprevious_property_change):
11663 (Fremove_list_of_text_properties): Remove decls.
11664 * keyboard.c (Fthis_command_keys): Remove decl.
11665 (Fcommand_execute): New forward static decl.

11668 * keymap.h (Flookup_key): Remove decl.
11669 * process.c (Fget_process): New forward static decl.
11670 (Fprocess_datagram_address): Mark as internal.

11681 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
11683 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
11686 2011-04-13 Eli Zaretskii <eliz@gnu.org>
11688 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
11689 when at ZV. (Bug#8487)
11691 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
11693 * charset.c (Fclear_charset_maps): Use xfree instead of free.
11695 * keyboard.c (parse_tool_bar_item): Likewise.
11696 * sound.c (sound_cleanup, alsa_close): Likewise.
11697 * termcap.c (tgetent): Likewise.
11698 * xfns.c (x_default_font_parameter): Likewise.
11699 * xsettings.c (read_and_apply_settings): Likewise.
11701 * alloc.c (overrun_check_malloc, overrun_check_realloc)
11702 (overrun_check_free): Protoize.
11704 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
11706 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
11707 since callers should never pass a negative size.
11708 Change the signature to match that of plain 'read' and 'write'; see
11709 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
11710 * lisp.h: Update prototypes of emacs_write and emacs_read.
11712 2011-04-11 Eli Zaretskii <eliz@gnu.org>
11714 * xdisp.c (redisplay_window): Don't try to determine the character
11715 position of the scroll margin if the window start point w->startp
11716 is outside the buffer's accessible region. (Bug#8468)
11718 2011-04-10 Eli Zaretskii <eliz@gnu.org>
11720 Fix write-region and its subroutines for buffers > 2GB.
11721 * fileio.c (a_write, e_write): Modify declaration of arguments and
11722 local variables to support buffers larger than 2GB.
11723 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
11725 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
11726 argument, local variables, and return value.
11728 * lisp.h: Update prototypes of emacs_write and emacs_read.
11730 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
11732 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
11734 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
11736 Fix more problems found by GCC 4.6.0's static checks.
11738 * xdisp.c (vmessage): Use a better test for character truncation.
11740 * charset.c (load_charset_map): <, not <=, for optimization,
11741 and to avoid potential problems with integer overflow.
11742 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
11743 * casetab.c (set_identity, shuffle): Likewise.
11744 * editfns.c (Fformat): Likewise.
11745 * syntax.c (skip_chars): Likewise.
11747 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
11748 This also lets GCC 4.6.0 generate slightly better loop code.
11750 * callint.c (Fcall_interactively): <, not <=, for optimization.
11751 (Fcall_interactively): Count the number of arguments produced,
11752 not the number of arguments given. This is simpler and lets GCC
11753 4.6.0 generate slightly better code.
11755 * ftfont.c: Distingish more carefully between FcChar8 and char.
11756 The previous code passed unsigned char * to a functions like
11757 strlen and xstrcasecmp that expect char *, which does not
11758 conform to the C standard.
11759 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
11760 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
11761 char * when the C standard requires it.
11763 * keyboard.c (read_char): Remove unused var.
11765 * eval.c: Port to Windows vsnprintf (Bug#8435).
11766 Include <limits.h>.
11767 (SIZE_MAX): Define if the headers do not.
11768 (verror): Do not give up if vsnprintf returns a negative count.
11769 Instead, grow the buffer. This ports to Windows vsnprintf, which
11770 does not conform to C99. Problem reported by Eli Zaretskii.
11771 Also, simplify the allocation scheme, by avoiding the need for
11772 calling realloc, and removing the ALLOCATED variable.
11774 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
11776 Remove invocations of doprnt, as Emacs now uses vsnprintf.
11777 But keep the doprint source code for now, as we might revamp it
11778 and use it again (Bug#8435).
11779 * lisp.h (doprnt): Remove.
11780 * Makefile.in (base_obj): Remove doprnt.o.
11781 * deps.mk (doprnt.o): Remove.
11783 error: Print 32- and 64-bit integers portably (Bug#8435).
11784 Without this change, on typical 64-bit hosts error ("...%d...", N)
11785 was used to print both 32- and 64-bit integers N, which relied on
11786 undefined behavior.
11787 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
11788 * lisp.h (error, verror): Mark as printf-like functions.
11789 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
11790 Report overflow in size calculations when allocating printf buffer.
11791 Do not truncate output string at its first null byte.
11792 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
11793 Truncate the output at a character boundary, since vsnprintf does not
11795 * charset.c (check_iso_charset_parameter): Convert internal
11796 character to string before calling 'error', since %c now has the
11798 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
11799 overflow when computing char to be passed to 'error'. Do not
11800 pass Lisp_Object to 'error'; pass the integer instead.
11801 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
11802 formatted with plain %d.
11804 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
11806 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
11808 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
11810 * xterm.c (x_catch_errors): Remove duplicate declaration.
11812 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
11814 * xdisp.c, lisp.h (message_nolog): Remove; unused.
11816 2011-04-10 Jim Meyering <meyering@redhat.com>
11818 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
11819 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
11820 return ssize_t not "int", and use size_t as the buffer length.
11821 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
11822 * gnutls.h: Update declarations.
11823 * process.c (read_process_output): Use ssize_t, to match.
11824 (send_process): Likewise.

11833 Use unsigned char, to match FcChar8 type definition.
11835 * xterm.c (handle_one_xevent):
11836 * xmenu.c (create_and_show_popup_menu):
11837 * xselect.c (x_decline_selection_request)
11838 (x_reply_selection_request): Avoid type-punned deref of X events.
11840 2011-04-09 Eli Zaretskii <eliz@gnu.org>
11842 Fix some uses of `int' instead of EMACS_INT.
11843 * search.c (string_match_1, fast_string_match)
11844 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
11845 (scan_buffer, find_next_newline_no_quit)
11846 (find_before_next_newline, search_command, Freplace_match)

11939 This avoids several warnings with gcc -Wstrict-overflow.
11940 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
11941 directly, rather than having caller test rule sign. This avoids
11942 some unnecessary tests.
11943 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
11944 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
11945 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
11947 * xfont.c (xfont_text_extents): Remove var that was set but not used.
11948 (xfont_open): Avoid unnecessary tests.
11950 * composite.c (composition_gstring_put_cache): Use unsigned integer.
11952 * composite.h, composite.c (composition_gstring_put_cache):
11953 Use EMACS_INT, not int, for length.
11955 * composite.h (COMPOSITION_DECODE_REFS): New macro,
11956 breaking out part of COMPOSITION_DECODE_RULE.
11957 (COMPOSITION_DECODE_RULE): Use it.
11958 * composite.c (get_composition_id): Remove unused local vars,
11959 by using the new macro.
11961 * textprop.c (set_text_properties_1): Change while to do-while,
11962 since the condition is always true at first.
11964 * intervals.c (graft_intervals_into_buffer): Mark var as used.
11965 (interval_deletion_adjustment): Return unsigned value.
11968 * process.c (list_processes_1, create_pty, read_process_output):

11984 * print.c (print_error_message): Avoid int overflow.
11986 * font.c (font_list_entities): Redo for clarity,
11987 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
11989 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
11990 (font_score): Avoid potential overflow in diff calculation.

11993 (sxhash): Redo loop for clarity and to avoid wraparound warning.
11995 * eval.c (funcall_lambda): Rename local to avoid shadowing.
11997 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
11998 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
11999 can always succeed if overflow has undefined behavior.
12001 * search.c (boyer_moore, wordify): Remove vars set but not used.
12002 (wordify): Omit three unnecessary tests.
12004 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

12013 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12014 (Finsert_file_contents): Remove unnecessary code checking fd.
12016 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12017 Check for integer overflow on size calculations.
12019 * buffer.c (Fprevious_overlay_change): Remove var that is set
12022 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12023 Remove vars that are set but not used.
12024 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12025 (timer_check_2): Mark vars as initialized.
12027 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12029 * image.c (lookup_image): Remove var that is set but not used.
12030 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12032 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12033 that are set but not used.
12035 * xfns.c (make_invisible_cursor): Don't return garbage
12036 if XCreateBitmapFromData fails (Bug#8410).
12038 * xselect.c (x_get_local_selection, x_handle_property_notify):
12039 Remove vars that are set but not used.
12041 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12042 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12044 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12045 Remove var that is set but not used.
12046 (scroll_bar_windows_size): Now size_t, not int.
12047 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12048 Check for overflow.
12050 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12051 (map_tty_color) [!defined MSDOS]: Likewise.
12053 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12055 * coding.c: Remove vars that are set but not used.
12056 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12057 All callers changed.
12058 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12059 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12060 (decode_coding_charset): Remove vars that are set but not used.
12062 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12063 that is set but not used.
12065 * print.c (print_object): Remove var that is set but not used.
12067 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12068 The gnulib version avoids calling malloc in the usual case,
12069 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12070 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12071 * filelock.c (current_lock_owner): Likewise.
12072 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12073 * sysdep.c: Include allocator.h, careadlinkat.h.
12074 (emacs_no_realloc_allocator): New static constant.
12075 (emacs_readlink): New function.
12076 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12077 ../lib/careadlinkat.h.
12079 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12081 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12082 first non-nil return value).

12086 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
12087 if not defined (Bug#8403).
12089 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12091 * xdisp.c (display_count_lines): Remove parameter `start',
12092 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12093 (get_char_face_and_encoding): Remove parameter `multibyte_p',
12094 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

12096 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
12097 and thereabouts. All callers changed.
12098 (get_per_char_metric): Remove parameter `f', unused since
12099 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12101 2011-04-02 Jim Meyering <meyering@redhat.com>
12103 do not dereference NULL upon failed strdup
12104 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12105 (ns_get_family): Likewise.
12107 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12109 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12111 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12113 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12116 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12118 Add lexical binding.
12120 * window.c (Ftemp_output_buffer_show): New fun.
12121 (Fsave_window_excursion):
12122 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
12124 * lread.c (lisp_file_lexically_bound_p): New function.
12125 (Fload): Bind Qlexical_binding.
12126 (readevalloop): Remove `evalfun' arg.
12127 Bind Qinternal_interpreter_environment.
12128 (Feval_buffer): Bind Qlexical_binding.
12129 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12131 (syms_of_lread): Declare `lexical-binding'.
12133 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12135 * keyboard.c (eval_dyn): New fun.
12136 (menu_item_eval_property): Use it.
12138 * image.c (parse_image_spec): Use Ffunctionp.
12140 * fns.c (concat, mapcar1): Accept byte-code-functions.
12142 * eval.c (Fsetq): Handle lexical vars.
12143 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12144 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12145 (FletX, Flet): Obey lexical binding.
12146 (Fcommandp): Handle closures.
12147 (Feval): New `lexical' arg.
12148 (eval_sub): New function extracted from Feval. Use it almost
12149 everywhere where Feval was used. Look up vars in lexical env.
12151 (Ffunctionp): Move from subr.el.
12152 (Ffuncall): Handle closures.
12153 (apply_lambda): Remove `eval_flags'.
12154 (funcall_lambda): Handle closures and new byte-code-functions.
12155 (Fspecial_variable_p): New function.
12156 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12157 but without exporting it to Lisp.
12159 * doc.c (Fdocumentation, store_function_docstring):
12160 * data.c (Finteractive_form): Handle closures.
12162 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12165 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12167 (exec_byte_code): New function extracted from Fbyte_code to handle new
12168 calling convention for byte-code-functions. Add new byte-codes.
12170 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
12172 * alloc.c (Fmake_symbol): Init new `declared_special' field.
12174 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12176 * xdisp.c (redisplay_internal): Fix prototype.
12178 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12180 * xdisp.c (SCROLL_LIMIT): New macro.
12181 (try_scrolling): Use it when setting scroll_limit.
12182 Limit scrolling to 100 screen lines.
12183 (redisplay_window): Even when falling back on "recentering",
12184 position point in the window according to scroll-conservatively,
12185 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12187 (try_scrolling): When point is above the window, allow searching
12188 as far as scroll_max, or one screenful, to compute vertical
12189 distance from PT to the scroll margin position. This prevents
12190 try_scrolling from unnecessarily failing when
12191 scroll-conservatively is set to a value slightly larger than the
12192 window height. Clean up the case of PT below the margin at bottom
12193 of window: scroll_max can no longer be INT_MAX. When aggressive
12194 scrolling is in use, don't let point enter the opposite scroll
12195 margin as result of the scroll.
12196 (syms_of_xdisp) <scroll-conservatively>: Document the
12197 threshold of 100 lines for never-recentering scrolling.
12199 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12201 * dispextern.h (move_it_by_lines):
12202 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
12203 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
12204 (message_log_check_duplicate): Remove parameters `prev_bol' and
12205 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12206 (redisplay_internal): Remove parameter `preserve_echo_area',
12207 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12209 * indent.c (Fvertical_motion):
12210 * window.c (window_scroll_pixel_based, Frecenter):
12211 Don't pass `need_y_p' to `move_it_by_lines'.
12213 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12215 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12216 steal a few bits to be more compact.
12217 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12218 Remove unneeded casts.
12220 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12222 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12224 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12225 binding" message (bug#7967).
12227 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12229 Fix more problems found by GCC 4.6.0's static checks.
12231 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12232 Remove unused local var.
12234 * editfns.c (Fmessage_box): Remove unused local var.
12236 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12237 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12238 Omit unused local vars.
12239 * window.c (shrink_windows): Omit unused local var.
12240 * menu.c (digest_single_submenu): Omit unused local var.
12241 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12242 Omit unused local var.
12244 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12245 Don't assume string length fits in int.
12246 (keyremap_step, read_key_sequence): Use size_t for sizes.
12247 (read_key_sequence): Don't check last_real_key_start redundantly.
12249 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
12250 instead of alloca (Bug#8344).
12252 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12253 (Fbacktrace_frame): Don't assume nframes fits in int.
12255 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
12257 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
12260 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12262 * cm.c (calccost): Turn while-do into do-while, for clarity.
12264 * keyboard.c (syms_of_keyboard): Use the same style as later
12265 in this function when indexing through an array. This also
12266 works around GCC bug 48267.
12268 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12270 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12272 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12273 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12275 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12276 This avoids undefined behavior on integer overflow, and is a bit
12277 more convenient anyway since it is compared to a size_t variable.
12279 Variadic C functions now count arguments with size_t, not int.
12280 This avoids an unnecessary limitation on 64-bit machines, which
12281 caused (substring ...) to crash on large vectors (Bug#8344).
12282 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
12283 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
12284 All variadic functions and their callers changed accordingly.

12504 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12506 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

12509 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12511 Fix more problems found by GCC 4.5.2's static checks.
12513 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12514 the first time through the loop, since we know p0 < p1 then.
12515 This also avoids a gcc -Wstrict-overflow warning.
12517 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12518 leading to a memory leak, possible in functions like
12519 load_charset_map_from_file that can allocate an unbounded number
12520 of objects (Bug#8318).
12522 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12523 that could (at least in theory) be that large.
12525 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12526 This is less likely to overflow, and avoids undefined behavior if
12527 overflow does occur. All callers changed. Use strtoul to scan

12545 * process.c (Fmake_network_process): Use socklen_t, not int,
12546 where POSIX says socklen_t is required in portable programs.
12547 This fixes a porting bug on hosts like 64-bit HP-UX, where
12548 socklen_t is wider than int (Bug#8277).
12549 (Fmake_network_process, server_accept_connection):
12550 (wait_reading_process_output, read_process_output):
12553 * process.c: Rename or move locals to avoid shadowing.

12565 Include tparam.h instead, since it declares them.
12566 * cm.h (PC): Remove extern decl; tparam.h now does this.
12567 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12568 * terminfo.c: Include tparam.h, to check interfaces.
12569 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12570 (tparam): Adjust signature to match interface in tparam.h;
12571 this removes some undefined behavior. Check that outstring and len
12572 are zero, which they always are with Emacs.
12573 * tparam.h (PC, BC, UP): New extern decls.
12575 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12576 (xftfont_open): Rename locals to avoid shadowing.

12594 (composition_update_it): Mark var as initialized.
12595 (find_automatic_composition): Mark vars as initialized,
12596 with a FIXME (Bug#8290).

12615 Fix pointer signedness.
12616 (alsa_choose_format): Remove unused local var.
12617 (wav_play): Initialize a variable to 0, to prevent undefined
12618 behavior (Bug#8278).
12620 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
12622 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
12624 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
12625 clobbering (Bug#8298).
12626 * sysdep.c (sys_subshell): Likewise.
12627 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12629 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
12630 This should get cleaned up, so that child_setup has the
12631 same signature on all platforms.
12633 * callproc.c (call_process_cleanup): Now static.
12634 (relocate_fd): Rename locals to avoid shadowing.
12636 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
12638 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
12639 not to be necessary, and produces flickering.
12641 2011-03-20 Glenn Morris <rgm@gnu.org>
12643 * config.in: Remove file.
12645 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

12690 Define only if needed.
12692 * unexelf.c (unexec): Name an expression,
12693 to avoid gcc -Wbad-function-cast warning.
12694 Use a different way to cause a compilation error if anyone uses
12695 n rather than nn, a way that does not involve shadowing.
12696 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
12698 * deps.mk (unexalpha.o): Remove; unused.

12763 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
12764 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
12765 some of which prompt warnings from gcc -Wbad-function-cast.
12766 (Fformat_time_string, Fencode_time, Finsert_char):

12795 (Fmemory_limit): Cast sbrk's returned value to char *.
12797 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

12803 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12804 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
12805 to use the following functions instead of these macros.
12806 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
12807 EMACS_INT, since callers assume the returned value fits in int.
12808 (upcase1): Likewise, for UPCASE_TABLE.
12809 (uppercasep, lowercasep, upcase): New static inline functions.
12810 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

12820 (regex_compile, re_match_2_internal): Mark locals as initialized.
12821 (RETALLOC_IF): Define only if needed.
12822 (WORDCHAR_P): Likewise. This one is never needed, but is used
12823 only in a comment talking about a compiler bug, so put inside
12824 the #if 0 of that comment.
12825 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
12826 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

12852 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
12853 New macros, so that the caller can use some names other than
12854 gcpro1, gcpro2, etc.
12855 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
12857 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
12858 argument, for consistency with GCPRO2_VAR, etc: it is now the
12859 prefix of the variable, not the variable itself. All uses
12861 * dired.c (directory_files_internal, file_name_completion):
12862 Rename locals to avoid shadowing.
12864 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
12865 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
12866 dired.c's scmp function, had undefined behavior.
12867 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12868 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
12869 * buffer.h: ... to here, because these macros use current_buffer,
12870 and the new implementation with inline functions needs to have
12871 current_buffer in scope now, rather than later when the macros
12873 (downcase, upcase1): New static inline functions.
12874 (DOWNCASE, UPCASE1): Reimplement using these functions.
12875 This avoids undefined behavior in expressions like
12876 DOWNCASE (x) == DOWNCASE (y), which previously suffered
12877 from race conditions in accessing the global variables
12878 case_temp1 and case_temp2.
12879 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
12880 * lisp.h (case_temp1, case_temp2): Remove their decls.
12881 * character.h (ASCII_CHAR_P): Move from here ...
12882 * lisp.h: ... to here, so that the inline functions mentioned
12883 above can use them.

12887 * fileio.c (file_name_as_directory, directory_file_name):

12890 (file_name_as_directory): Use const pointers when appropriate.
12891 (Fexpand_file_name): Likewise. In particular, newdir might
12892 point at constant storage, so make it a const pointer.

12894 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
12896 (Fset_file_times, Finsert_file_contents, auto_save_error):

12901 to avoid shadowing.
12903 * marker.c (bytepos_to_charpos): Remove; unused.
12905 * lisp.h (verify_bytepos, count_markers): New decls,
12906 so that gcc does not warn that these functions aren't declared.
12908 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
12909 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
12910 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
12911 (copy_text): Remove unused local var.

12916 * buffer.c (fix_overlays_before): Mark locals as initialized.
12917 (fix_start_end_in_overlays): Likewise. This function should be
12918 simplified by using pointers-to-pointers, but that's a different

12921 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
12922 (report_overlay_modification): Rename locals to avoid shadowing.

12927 to suppress a gcc -Wclobbered warning that does not seem to be right.
12928 (MAXPATHLEN): Define only if needed.
12930 * process.c (serial_open, serial_configure): Move decls from here ...
12931 * systty.h: ... to here, so that they can be checked.
12933 * fns.c (get_random, seed_random): Move extern decls from here ...
12934 * lisp.h: ... to here, so that they can be checked.
12936 * sysdep.c (reset_io): Now static.

13095 For example, without this patch (encode-time 0 0 0 1 1
13096 1152921504606846976) returns the obviously-bogus value (-948597
13097 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
13098 reports time overflow. See
