3 Assume perror.
4 * s/hpux10-20.h (HAVE_PERROR): Remove.
5 * sysdep.c (perror) [HPUX && !HAVE_PERROR]:
6 Remove dummy definition, as this problem was obsolete long ago.
8 Assume strerror.
9 * sysdep.c (strerror) [!HAVE_STRERROR && !WINDOWSNT]: Remove.
11 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
13 Avoid calls to strlen in font processing functions.
14 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
15 (font_open_by_name): Changed to use length argument. Adjust
16 users accordingly.
17 * font.h (font_open_by_name, font_parse_xlfd): Adjust prototypes.
18 * xfont.c (xfont_decode_coding_xlfd): Changed to return ptrdiff_t.

31 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
33 Remove "#define unix" that is no longer needed (Bug#11905).
34 * s/aix4-2.h (unix): Remove; no longer needed.
36 EMACS_TIME simplification (Bug#11875).
37 This replaces macros (which typically do not work in GDB)
38 with functions, typedefs and enums, making the code easier to debug.
39 The functional style also makes code easier to read and maintain.
40 * systime.h: Include <sys/time.h> on all hosts, not just if
41 WINDOWSNT, since 'struct timeval' is needed in general.
42 (EMACS_TIME): Now a typedef, not a macro.
43 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
44 not macros.
45 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
46 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
47 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
48 (EMACS_TIME_LE): Now functions, not macros.
49 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
50 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
51 which are not functions. All uses rewritten to use:
52 (make_emacs_time): New function.
53 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
54 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
55 not functions. All uses rewritten to use the following, respectively:
56 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
57 (add_emacs_time, sub_emacs_time): New functions.
58 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
59 * fileio.c (Fcopy_file):
60 * xterm.c (XTflash): Get the current time closer to when it's used.
61 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

65 Simplify by avoiding confusing use of strncpy etc.
66 * doc.c (Fsnarf_documentation):
67 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
68 * frame.c (Fmake_terminal_frame):
69 * gtkutil.c (get_utf8_string):
70 * lread.c (openp):
71 * nsmenu.m (ns_update_menubar):
72 * regex.c (regerror):
73 Prefer memcpy to strncpy and strncat when either will do.
74 * fileio.c (Fsubstitute_in_file_name):
75 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
76 (menu_separator_name_p):
77 * nsmenu.m (ns_update_menubar):
78 Prefer memcmp to strncmp when either will do.
79 * nsterm.m: Include <ftoastr.h>.
80 (ns_get_color):
81 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
82 Prefer snprintf to strncpy.
83 * nsterm.m (ns_term_init):
84 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
85 * nsterm.m (ns_term_init):
86 Avoid the need for strncpy, by using build_string or
87 make_unibyte_string directly. Use dtoastr, not snprintf.
88 * process.c (Fmake_network_process): Diagnose service names that
89 are too long, rather than silently truncating them or creating
90 non-null-terminated names.
91 (Fnetwork_interface_info): Likewise, for interface names.
92 * sysdep.c (system_process_attributes) [GNU_LINUX]:
93 Prefer sprintf to strncat.
94 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
95 Prefer vsnprintf to vsprintf + strncpy.
97 2012-07-10 Glenn Morris <rgm@gnu.org>
99 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
100 Clarify fallback case.
102 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
104 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
105 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
106 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
107 * w32menu.c, window.c, xmenu.c: Changed to use XCAR and XCDR
108 where argument type is known to be a Lisp_Cons.
110 2012-07-10 Tom Tromey <tromey@redhat.com>
112 * bytecode.c (BYTE_CODE_THREADED): New macro.
113 (BYTE_CODES): New macro. Replaces all old byte-code defines.
114 (enum byte_code_op): New type.
115 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
116 (exec_byte_code): Use them. Use token threading when applicable.
118 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
120 Optimize pure C strings initialization.
121 * lisp.h (make_pure_string): Fix prototype.
122 (build_pure_c_string): New function, defined as static inline. This
123 provides a better opportunity to optimize away calls to strlen when
124 the function is called with compile-time constant argument.
125 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
126 argument, adjust users accordingly. Use build_pure_c_string where
127 appropriate.
128 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
129 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
130 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
132 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
134 Avoid calls to strlen in miscellaneous functions.
135 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
136 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
137 * lread.c (openp): Likewise.

143 srclen argument and return the length of result. Adjust users
144 accordingly.
145 (directory_file_name): Fix comment. Change to add srclen argument,
146 swap 1st and 2nd arguments to obey the common convention. Adjust
147 users accordingly.
148 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
150 2012-07-10 Glenn Morris <rgm@gnu.org>
152 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
153 Move PENDING_OUTPUT_COUNT definition to configure.
155 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
156 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
157 * s/gnu.h (DATA_START): Move definitions to configure.
159 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
160 We include usg5-4-common.h, which defines them both.
162 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
163 O_RDONLY already includes it).
165 Stop ns builds setting the EMACSLOADPATH environment variable.
166 * nsterm.m (ns_load_path): Rename from ns_init_paths.
167 Now it does not set EMACSLOADPATH, just returns the load-path string.
168 * nsterm.h: Update accordingly.
169 * lread.c [HAVE_NS]: Include nsterm.h.
170 (init_lread) [HAVE_NS]: Use ns_load_path.
171 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
173 2012-07-09 Glenn Morris <rgm@gnu.org>
175 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
176 since the included bsd-common.h does so.
178 Stop ns builds setting the EMACSPATH environment variable.
179 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
180 (ns_init_paths): Do not set EMACSPATH.
181 * nsterm.h (ns_exec_path): Add it.
182 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
183 Use ns_exec_path.
185 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
187 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
189 * process.c (wait_reading_process_output): 'waitchannels' was unset
190 when read_kbd || !NILP (wait_for_cell); fix this.
192 Add GCC-style 'const' attribute to functions that can use it.
193 * character.h (char_resolve_modifier_mask):
194 * keyboard.h (make_ctrl_char):
195 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
196 (init_character_once, next_almost_prime, init_fns, init_image)
197 (flush_pending_output, init_sound):
198 * mem-limits.h (start_of_data):

203 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
204 Add decls with ATTRIBUTE_CONST.
206 Minor improvements to make_formatted_string.
207 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
208 where int is good enough, as vsprintf returns an int.
209 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
211 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
213 Use make_formatted_string to avoid double length calculation.
214 * lisp.h (make_formatted_string): New prototype.
215 * alloc.c (make_formatted_string): New function.
216 * buffer.c (Fgenerate_new_buffer_name): Use it.

238 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
240 Move marker debugging code under MARKER_DEBUG.
241 * marker.c (MARKER_DEBUG): Move marker debugging code under
242 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
243 for bootstrap with --enable-checking (~3x slowdown reported
244 by Juanma Barranquero <lekktu@gmail.com>).
245 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
247 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
249 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
250 See <http://bugs.gnu.org/11825#29>.
252 2012-07-08 Eli Zaretskii <eliz@gnu.org>
254 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
255 has no font, use the frame's font. (Bug#11813)
256 (display_line): Add commentary about displaying truncation glyphs
257 on GUI frames.
258 (produce_special_glyphs): Move here from term.c.
260 * term.c (produce_special_glyphs): Move to xdisp.c.
262 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
263 section.
265 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
267 * xdisp.c (display_line): Avoid warning about implicit declaration
268 of FRAME_FONT.
270 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
272 * lisp.h: Remove empty conditional.
274 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
276 * lread.c (load_path_check): Now static.
278 Fix some minor --with-ns problems found by static checking.
279 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
280 (x_set_font) [!HAVE_X_WINDOWS]:
281 * image.c (xpm_load_image) [HAVE_NS]:
282 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
283 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
284 Remove unused local.
285 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
286 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
287 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
288 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
289 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
290 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
291 Fix pointer signedness problem.
292 * xfaces.c (FRAME_X_FONT_TABLE):
293 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
295 2012-07-07 Glenn Morris <rgm@gnu.org>
297 * lread.c (load_path_check): New function, split from init_lread.
298 (init_lread): Reorganize. Motivation:
299 If EMACSLOADPATH is set, check/warn about that rather than the
300 defaults, which we are not going to use. Hence we can remove
301 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
302 Don't warn if site-lisp directories are missing.
303 If not installed, start from a blank load-path, since
304 PATH_LOADSEARCH refers to the eventual installation directories.
306 2012-07-07 Eli Zaretskii <eliz@gnu.org>
308 Support truncation and continuation glyphs on GUI frames, when
309 fringes are disabled. (Bug#11832)
310 * xdisp.c (init_iterator): Get dimensions of truncation and
311 continuation glyphs even if on GUI frames. Adjust
312 it->last_visible_x on GUI frames when the left or right fringes,
313 or both, are absent.
314 (start_display, move_it_in_display_line_to): Handle the case of a
315 GUI frame without a fringe to display continuation or truncation
316 glyphs.
317 (insert_left_trunc_glyphs): Support GUI frames: make sure
318 truncation glyphs overwrite enough glyphs from the current line to
319 have sufficient space in pixels.
320 (display_line): Support truncation and continuation glyphs on GUI
321 frames. If some spare pixels are left on the line after inserting
322 the truncation glyphs, fill that space with a stretch glyph of a
323 suitably computed width.
325 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
326 produce_glyphs, to support GUI sessions.
328 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
330 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
332 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
334 Do not require float-time's arg to fit in time_t (Bug#11825).
335 This works better on hosts where time_t is unsigned, and where
336 float-time is applied to the (negative) difference between two times.
337 * editfns.c (decode_time_components): Last arg is now double *,
338 not int *, and means to store all the result as a double, without
339 worrying about whether the seconds part fits in time_t.
340 All callers changed.
341 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
342 All callers changed.
343 (Ffloat_time): Do not fail merely because the specified time falls
344 outside of time_t range.
346 2012-07-07 Glenn Morris <rgm@gnu.org>
348 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

350 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
352 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
354 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
355 Update dependencies.
357 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
359 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
361 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
362 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
363 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
364 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
365 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
366 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
368 * xfont.c (compare_font_names): Redo to omit the need for casts.
370 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
372 * xfns.c (Fx_change_window_property): Doc fix.
373 * w32fns.c (Fx_change_window_property): Doc fix.
375 * w32fns.c (Fx_window_property): Accept the same arguments as the
376 X Windows version. Doc fix.
377 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
379 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
380 Eli Zaretskii <eliz@gnu.org>
382 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
383 Windows-specific code from nt/config.nt moved here.
384 Obsolete settings removed.
386 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
388 * process.c: Avoid unnecessary calls to gettime.
389 (wait_reading_process_output): Don't get the time of day
390 when gobbling data immediately and not waiting, as there's no need
391 for it in that case. This removes a FIXME.
393 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
395 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
396 is defined (Bug#11768).
398 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
400 Fix marker debugging code.
401 * marker.c (byte_char_debug_check): Do not perform the check
402 if buffer is not multibyte.
403 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
404 Call byte_char_debug_check with correct arguments.
406 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
408 Compile marker debugging code only if ENABLE_CHECKING is defined.
409 * marker.c (byte_char_debug_check, count_markers):
410 Use only if ENABLE_CHECKING is defined.
411 (byte_debug_flag): Remove.
412 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
413 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
415 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
417 Avoid code repetition in marker-related functions.
418 * marker.c (attach_marker): New function.
419 (Fset_marker, set_marker_restricted, set_marker_both)
420 (set_marker_restricted_both): Use it.
421 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
422 Consistently rename charno to charpos.
423 (marker_position): Add eassert.
424 (marker_byte_position): Convert to eassert.
426 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
428 Simplify list operations in unchain_overlay and unchain_marker.
429 * buffer.c (unchain_overlay): Simplify. Add comment.
430 * marker.c (unchain_marker): Simplify. Fix comments.
432 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

443 * window.c (save_window_save): Likewise.
445 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
447 Do not use Fdelete_overlay in delete_all_overlays
448 to avoid redundant calls to unchain_overlay.
449 * buffer.c (drop_overlay): New function.
450 (delete_all_overlays, Fdelete_overlay): Use it.
451 * minibuf.c (get_minibuffer): Fix comment.
453 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
455 Port to OpenBSD 5.1 amd64.
456 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
457 This is needed for OpenBSD, and should be harmless on all BSD systems.
458 Also, include <sys/sysctl.h>, as it should be available on all
459 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
460 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
461 use p_pid member, not kp_proc.pid.
463 2012-07-06 Glenn Morris <rgm@gnu.org>
465 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
467 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
469 More xmalloc and related cleanup.

479 * xterm.c:
480 Omit needless casts involving void * pointers and allocation.
481 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
482 as the former is more robust if P's type is changed.
483 Prefer xzalloc to xmalloc + memset 0.
484 Simplify malloc-or-realloc to realloc.
485 Don't worry about xmalloc returning a null pointer.
486 Prefer xstrdup to xmalloc + strcpy.
487 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
488 growing it.
489 * keyboard.c (apply_modifiers_uncached): Prefer local array to
490 alloca of a constant.
492 2012-07-05 Eli Zaretskii <eliz@gnu.org>
494 * xdisp.c (display_line): Fix horizontal pixel coordinates when
495 hscroll is larger than the line width. Fixes long and futile
496 looping inside extend_face_to_end_of_line (on a TTY) producing
497 glyphs that are not needed and thrown away.
499 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
501 * marker.c (set_marker_restricted_both): Simplify by using
502 clip_to_bounds.
504 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
506 * editfns.c (region_limit): Simplify by using clip_to_bounds.
508 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
510 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
511 not defined (Bug#11768).

513 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
514 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
515 followed by gtk_box_set_homogeneous (Bug#11768).
516 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
517 (update_theme_scrollbar_width, xg_create_scroll_bar):
518 Use gtk_scrollbar_new (Bug#11768).
519 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
520 (is_box_type): New function (Bug#11768).

527 * xdisp.c (window_hscroll_limited): New function.
528 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
529 coordinates when window's hscroll is set to insanely large
530 values. (Bug#11857)
532 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
534 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

596 Problem reported by Troels Nielsen in
597 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
599 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
601 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
602 This should be fixed in a better way; see Eli Zaretskii in
603 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
604 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
606 * fileio.c (time_error_value): Rename from special_mtime.
607 The old name's problems were noted by Eli Zaretskii in
608 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
610 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
611 This variable's comment says Emacs needs at least one GDB-visible
612 symbol of type enum pvec_type, to work around GDB problems.
613 The symbol's value doesn't matter.
615 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
616 that causes compilation to fail on pre-C99 compilers.
618 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
620 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

623 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
625 * buffer.c (init_buffer_once): Fix initialization of
626 headers for buffer_defaults and buffer_local_symbols.
627 Reported by Juanma Barranquero <lekktu@gmail.com>.
629 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
631 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
632 * lisp.h (enum pvec_type): Use fewer bits.
633 (PSEUDOVECTOR_SIZE_BITS): New constant.
634 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
635 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
636 change in pvec_type.
637 (PSEUDOVECTOR_TYPEP): New macro.

640 * emacs.c (gdb_pvec_type): Update type.
641 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.

643 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
644 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
645 (sweep_vectors): Use it. Use local var `total_bytes' instead of
646 abusing vector->header.next.nbytes.
647 (live_vector_p): Use PVEC_TYPE.
648 (mark_object): Adapt code to extract pvectype. Use switch.
650 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
652 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
653 Tighten new eassert a bit.
655 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
657 Fix compilation with --enable-gcc-warnings and -O1
658 optimization level.
659 * doprnt.c (doprnt): Change type of tem to int, initialize
660 to avoid compiler warning. Add eassert.
661 * search.c (simple_search): Initialize match_byte to avoid
662 compiler warning. Add eassert.
664 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
666 Avoid weird behavior with large horizontal scrolls.
667 Without this change, for example, large hscroll values would
668 mess up Emacs's display on Fedora 15 x86, presumably due to
669 overflows in int calculations in the display code.
670 Also, if buffers had long lines, Emacs would freeze.
671 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
672 (set_window_hscroll): New function, containing the old guts of
673 Fset_window_hscroll. Return the clipped value.
674 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
675 This avoids the need to check against PTRDIFF_MAX.
677 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
679 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
681 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
683 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
685 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
686 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
687 since GCC 4.4.6 issues a bogus warning for them.
689 Fix bugs in file timestamp newness comparisons.
690 * fileio.c (Ffile_newer_than_file_p):
691 * lread.c (Fload): Use full timestamp resolution of files,
692 not just the 1-second resolution, so that files that are only
693 slightly newer still count as newer.
694 * fileio.c (Ffile_newer_than_file_p): Don't assume file
695 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
697 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
699 * fileio.c: Improve handling of file time marker. (Bug#11852)
700 (special_mtime): New function.
701 (Finsert_file_contents, Fverify_visited_file_modtime):
702 Use it to set special mtime values consistently.
704 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
706 * fileio.c (Finsert_file_contents): Properly handle st_mtime
707 marker for non-existing file. (Bug#11852)
709 2012-07-03 Glenn Morris <rgm@gnu.org>
711 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
712 and did not make it into globals.h).
714 2012-07-03 Tom Tromey <tromey@redhat.com>
716 * window.c (Fset_window_margins, Fset_window_fringes)
717 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
718 * textprop.c (Fprevious_property_change): No longer static.

721 static.

739 * buffer.h: Remove EXFUNs.
740 * dispextern.h: Remove EXFUNs.
741 * intervals.h: Remove EXFUNs.
742 * fontset.h: Remove EXFUN.
743 * font.h: Remove EXFUNs.
744 * dosfns.c (system_process_attributes): Remove EXFUN.

746 * lisp.h: Remove EXFUNs.
747 * w32term.h: Remove EXFUNs.
748 * window.h: Remove EXFUNs.
749 * xsettings.h: Remove EXFUN.
750 * xterm.h: Remove EXFUN.
752 2012-07-03 Glenn Morris <rgm@gnu.org>
754 * lisp.h (Frandom): Make it visible to C.
755 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
756 buffer for invisible buffers. (Bug#1229)
758 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
760 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
761 values which aren't power of 2.
762 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
763 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
764 accordingly.
766 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
768 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
770 * alloc.c (mark_object): Revert part of last patch to use `switch'.
772 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
774 * alloc.c (allocate_vector_block): Remove redundant
775 calls to mallopt if DOUG_LEA_MALLOC is defined.
776 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
777 avoid calls to mallopt if zero_vector is returned.
779 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
781 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
782 is enabled, avoid dereferencing NULL current_sblock if
783 running undumped.
785 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
787 Cleanup basic buffer management.
788 * buffer.h (struct buffer): Change layout to use generic vector
789 marking code. Fix some comments. Change type of 'clip_changed'
790 to bitfield. Remove unused #ifndef old.
791 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
792 (GET_OVERLAYS_AT): Fix indentation.
793 (for_each_per_buffer_object_at): New macro.

796 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
797 * alloc.c (allocate_buffer): Adjust to match new layout of
798 struct buffer. Fix comment.
799 (mark_overlay): New function.

801 Lisp area of struct buffer.
802 (mark_object): Use it. Adjust marking of misc objects
803 and related comments.
805 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
807 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
808 wrapper that is not needed because the wrapped code is a no-op (zero
809 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
810 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
812 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
814 * alloc.c (mark_buffer): Simplify. Remove prototype.
815 (mark_object): Add comment. Reorganize marking of vector-like
816 objects. Use CHECK_LIVE for all vector-like objects except buffers
817 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
818 redundant calls to mark_vectorlike for bool vectors.
820 2012-06-30 Glenn Morris <rgm@gnu.org>
822 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
824 * epaths.in (PATH_SITELOADSEARCH): New.
825 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
826 This is rather than relying on --enable-locallisppath elements
827 having "site-lisp" in their names. (Bug#10208#25, 11658)
829 2012-06-30 Eli Zaretskii <eliz@gnu.org>
831 * w32proc.c (sys_select): Accept and ignore one more argument.
833 * w32.c (emacs_gnutls_pull): Call select with one more argument.
835 * sysselect.h [DOS_NT]: Don't include sys/select.h.
836 (pselect) [!MS_DOS]: Redirect to sys_select.
838 * sysdep.c: Don't include dos.h and dosfns.h.
840 * process.c (sys_select):
841 * msdos.c (sys_select): Accept one more argument and ignore it.
843 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
844 adapt data types and code to that.
846 * dosfns.c:
847 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
848 which clashes with the gnulib function of the same name.
850 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
852 * font.c (font_style_to_value, font_style_symbolic)
853 (font_prop_validate_style): Add type checks for values in
854 font_style_table.
856 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
857 argument.
858 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
859 uses.
861 2012-06-29 Eli Zaretskii <eliz@gnu.org>
863 * xdisp.c (try_window_id): Undo last change.
865 * w32.c (getwd): Adjust commentary about startup_dir.
866 (init_environment): Always call sys_access, even in non-MSVC
867 builds. Don't chdir to the directory of the Emacs executable.
868 This undoes code from 1997 which was justified by the need to
869 "avoid conflicts when removing and renaming directories". But its
870 downside was that every relative file name was being interpreted
871 relative to the directory of the Emacs executable, which can never
872 be TRT. In particular, it broke sys_access when called with
873 relative file names.
874 (sys_access): Map GetLastError to errno.
876 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
878 * window.h (struct window): Change type of 'fringes_outside_margins'
879 to bitfield. Fix comment. Adjust users accordingly.

881 Adjust comment.
882 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
883 to ptrdiff_t.
885 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
887 * gnutls.c (emacs_gnutls_handshake):
888 Add QUIT to make the loop interruptible.
890 2012-06-29 Glenn Morris <rgm@gnu.org>
892 * charset.c (init_charset): Make lack of etc/charsets fatal.
894 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
896 * editfns.c (region_limit): Fix type mismatch.
898 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
900 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
901 undefined. Convert from xassert to eassert.
902 * nsmenu.m: Convert from xassert to eassert.
903 * nsterm.m: Likewise.
905 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
907 * editfns.c (region_limit): Clip to narrowing (bug#11770).
909 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
911 Avoid integer overflow on scroll-left and scroll-right.
912 * window.c (HSCROLL_MAX): New macro.
913 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
914 overflow when requested scroll falls outside ptrdiff_t range.
916 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
918 * window.h (struct window): Change type of 'hscroll',
919 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
920 'last_modified' and 'last_overlay_modified' to EMACS_INT.
921 Adjust users accordingly.
922 * xdisp.c (try_cursor_movement): Replace type check with eassert.
923 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
924 from EMACS_INT to ptrdiff_t.
925 (make_window): Omit redundant initialization.
927 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
929 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
931 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
933 * window.h (struct window): Change type of 'use_time' and
934 'sequence_number' from Lisp_Object to int.
935 * frame.c (make_frame): Adjust users accordingly.
936 * print.c (print_object): Likewise.
937 * window.c (select_window, Fwindow_use_time, make_parent_window)
938 (make_window): Likewise.

1066 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1068 Use sprintf return value instead of invoking strlen on result.
1069 In the old days this wasn't portable, since some sprintf
1070 implementations returned char *. But they died out years ago and
1071 Emacs already assumes sprintf returns int.
1072 Similarly for float_to_string.
1073 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
1074 * ccl.c (ccl_driver):

1080 * xfns.c (syms_of_xfns):
1081 Use sprintf or float_to_string result to avoid need to call strlen.
1082 * data.c (Fnumber_to_string):
1083 Use make_unibyte_string, since the string must be ASCII.
1084 * lisp.h, print.c (float_to_string): Now returns int length.
1085 * term.c (produce_glyphless_glyph):
1086 Use sprintf result rather than recomputing it.
1088 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1089 * Makefile.in (ALL_CFLAGS):
1090 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

1115 sprintf already null-terminates its output.
1117 * xfns.c (x_window): Remove redundant cast.
1119 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1121 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
1122 `const char *' to `char *' to avoid compiler warning.
1124 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1126 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1127 instead of truncating it to 63 (admittedly a generous limit).
1129 * process.c: Fix spelling and caps in comments.

1182 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1184 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
1185 * lisp.h (WAIT_READING_MAX): New macro.
1186 * dispnew.c (Fsleep_for, sit_for):
1187 * keyboard.c (kbd_buffer_get_event):
1188 * process.c (Faccept_process_output):
1189 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1190 This improves on the previous patch, which introduced a bug
1191 when time_t is unsigned and as wide as intmax_t.
1192 See <http://bugs.gnu.org/9000#51>.
1194 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1196 * dispnew.c (sit_for, Fsleep_for):
1197 * keyboard.c (kbd_buffer_get_event):

1212 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
1213 All uses changed.
1214 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
1215 not make_lisp_timeval, when the argument is of type EMACS_TIME.
1217 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1219 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
1220 last argument of make_unibyte_string.
1222 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
1223 language ID in the event parameters.
1225 * w32term.c (w32_read_socket): Put the new keyboard codepage into
1226 event.code, not the obscure "character set ID".
1228 2012-06-23 Chong Yidong <cyd@gnu.org>
1230 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
1232 2012-06-23 Eli Zaretskii <eliz@gnu.org>

1249 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
1250 Privately reported by Herbert J. Skuhra.
1251 [__FreeBSD__]: Remove "*/" typo after "#include".

1253 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
1254 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
1255 Don't assume EMACS_TIME and struct timeval are the same type.
1257 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1259 Support higher-resolution time stamps (Bug#9000).
1260 The time stamps are only nanosecond-resolution at the C level,
1261 since that's the best that any real-world system supports now.
1262 But they are picosecond-resolution at the Lisp level, as that's
1263 easy, and leaves room for future OS improvements.
1265 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1266 (LIBES): Use it.
1268 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1269 Don't get current time unless it's needed.
1271 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1272 now provides it if it's absent.
1273 (start_atimer): Port to higher-res time stamps.
1274 Check for time stamp overflow. Don't get current time more
1275 often than is needed.
1277 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1278 Include systime.h, not time.h.
1279 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1281 * dired.c: Include stat-time.h.
1282 (Ffile-attributes): File times now have higher resolution.
1284 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
1285 (struct image): Timestamp now has higher resolution.
1287 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1288 has at least microseconds now. All uses removed.
1289 (update_frame, update_single_window, update_window, update_frame_1)
1290 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1292 * editfns.c (time_overflow): Now extern.
1293 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1294 (float-time, Fformat_time_string, Fcurrent_time_string)
1295 (Fcurrent_time_zone): Accept and generate higher-resolution
1296 time stamps.
1297 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
1298 (decode_time_components, lisp_seconds_argument): New functions.
1299 (make_time): Now static.
1300 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1301 Report an error if the time is invalid, rather than having the caller
1302 do that.
1304 * fileio.c: Include <stat-time.h>
1305 (Fcopy_file): Copy higher-resolution time stamps.
1306 Prefer to set the time stamp via a file descriptor if that works.
1307 (Fset_file_times, Finsert_file_contents, Fwrite_region)
1308 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1309 (Fvisited_file_modtime, Fset_visited_file_modtime):
1310 Support higher-resolution time stamps.
1312 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1314 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1316 * image.c (prepare_image_for_display, clear_image_cache)
1317 (lookup_image): Port to higer-resolution time stamps.
1319 * keyboard.c (start_polling, bind_polling_period):
1320 Check for time stamp overflow.
1321 (read_char, kbd_buffer_get_event, timer_start_idle)
1322 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1323 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1324 Port to higher-resolution time stamps. Do not assume time_t is signed.
1325 (decode_timer): New function. Timers are now vectors of length 9,
1326 not 8, to accommodate the picosecond component.
1327 (timer_check_2): Use it.
1329 * nsterm.m (select_timeout, timeval_subtract): Remove.
1330 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1331 as they're a bit more accurate and handle overflow better.
1332 (ns_select): Change prototype to be compatible with pselect.
1333 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1334 * nsterm.h (ns_select): Adjust prototype.
1336 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1337 us-resolution time stamps.
1338 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1340 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1342 * lisp.h (time_overflow): New decl.
1343 (wait_reading_process_output): First arg is now intmax_t, not int,
1344 to accommodate larger waits.
1346 * process.h (struct Lisp_Process.read_output_delay):
1347 Now counts nanoseconds, not microseconds.
1348 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1349 EMACS_HAS_USECS.
1350 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1351 (wait_reading_process_output):
1352 Port to ns-resolution time stamps.
1353 (Faccept_process_output, wait_reading_process_output):
1354 Check for time stamp overflow. Do not assume time_t is signed.
1355 (select_wrapper): Remove; we now use pselect.
1356 (Fprocess_attributes): Now generates ns-resolution time stamps.
1358 * sysdep.c: Include utimens.h. Don't include utime.h
1359 or worry about struct utimbuf; gnulib does that for us now.
1360 (gettimeofday): Remove; gnulib provides a substitute.
1361 (make_timeval): New function.
1362 (set_file_times): Now sets ns-resolution time stamps.
1363 New arg FD; all uses changed.
1364 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1365 (system_process_attributes):
1366 Now returns ns-resolution time stamp. All uses changed.
1367 Check for time stamp overflow.
1369 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1370 provides a substitute now.
1372 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1373 since it guarantees struct timespec.
1374 (EMACS_TIME): Now struct timespec, so that we can support
1375 ns-resolution time stamps.
1376 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1377 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1378 (EMACS_USECS): Remove.
1379 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1380 so multiply the arg by 1000 before storing it.
1381 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1382 New macros.
1383 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
1384 Port to ns-resolution time stamps.
1385 (EMACS_TIME_NEG_P): Remove; replaced by....
1386 (EMACS_TIME_SIGN): New macro.
1387 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
1388 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
1389 (set_file_times, make_time, lisp_time_argument): Adjust signature.
1390 (make_timeval, make_lisp_time, decode_time_components): New decls.
1391 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1392 that it mishandled time_t overflow. You can't compare by subtracting!
1393 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1394 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1396 * term.c: Include <sys/time.h>.
1397 (timeval_to_Time): New function, for proper overflow wraparound.
1398 (term_mouse_position, term_mouse_click): Use it.
1400 * undo.c (record_first_change): Support higher-resolution time stamps
1401 in the undo buffer.
1402 (Fprimitive_undo): Use them when restoring time stamps.
1404 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1405 (w32_get_internal_run_time):
1406 Port to higher-resolution Emacs time stamps.
1407 (ltime): Now accepts single 64-bit integer, as that's more convenient
1408 for callers.
1410 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1412 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1413 for compatibility with pselect. Support ns-resolution time stamps.
1415 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1417 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1418 Check for time stamp overflow, and support ns-resolution time stamps.

1421 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1422 (timeval_subtract): Remove; no longer needed.
1423 (XTflash, XTring_bell, x_wait_for_event):

1430 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1432 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1433 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1434 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1435 staticidx goes up to 1597 out of 1600 = 0x640.)
1437 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1439 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1440 Otherwise, the umask might be mistakenly 0 while handling input signals.

1450 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
1451 access to `contents' member of Lisp_Vector objects with AREF and ASET
1452 where appropriate.
1454 2012-06-19 Chong Yidong <cyd@gnu.org>
1456 * frame.c (delete_frame): When selecting a frame on a different
1457 text terminal, do not alter the terminal's top-frame.
1459 * xdisp.c (format_mode_line_unwind_data): Record the target
1460 frame's selected window and its terminal's top-frame.
1461 (unwind_format_mode_line): Restore them.
1462 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
1463 Callers changed.
1464 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1465 since tty frames can be explicitly named.
1466 (prepare_menu_bars): Likewise.
1468 * term.c (Ftty_top_frame): New function.
1470 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1472 Port byte-code-meter to modern targets.
1473 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
1474 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
1475 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
1476 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
1477 (METER_1, METER_2): Simplify.
1479 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
1481 * data.c (Fdefalias): Return `symbol' (bug#11686).
1483 2012-06-18 Martin Rudalics <rudalics@gmx.at>
1485 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
1486 gets killed during executing of this function (Bug#11665).
1487 Try to always return Qt when the buffer has been actually killed.
1488 (Vkill_buffer_query_functions): In doc-string say that functions
1489 run by this hook should not change the current buffer.
1491 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1493 Fix recently-introduced process.c problems found by static checking.

1511 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
1513 * lisp.h (eassert): Assume C89 or later.
1514 This removes the need for CHECK.
1515 (CHECK): Remove. Its comments about always evaluating its
1516 argument were confusing, as 'eassert' typically does not evaluate
1517 its argument.
1519 * coding.c (produce_chars): Use ptrdiff_t, not int.
1521 * xterm.c (x_draw_underwave): Check for integer overflow.
1522 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
1524 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
1526 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

1544 (x_draw_glyph_string): Use it.
1546 2012-06-16 Juanma Barranquero <lekktu@gmail.com>
1548 * makefile.w32-in ($(BLD)/emacs.$(O), $(BLD)/fringe.$(O))

1613 2012-06-16 Eli Zaretskii <eliz@gnu.org>
1615 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
1616 If all the glyphs of the glyph row came from strings, and we have no
1617 cursor positioning clues, put the cursor on the first glyph of the
1618 row.
1619 (handle_face_prop): Use chunk-relative overlay string index when
1620 indexing into it->string_overlays array. (Bug#11653)
1621 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

1633 (Fdelete_window_internal): Don't access frame's mouse highlight
1634 info of the initial frame. (Bug#11677)
1636 2012-06-14 Paul Eggert <eggert@cs.ucla.edu>
1638 * .gdbinit (xgetint): Fix recently-introduced paren typo.
1639 Assume USE_2_TAGS_FOR_INTS.
1640 (xreload): Adjust $tagmask width to match recent lisp.h change.
1642 Simplify lisp.h in minor ways that should not affect code.
1643 * lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
1644 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
1645 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
1646 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
1647 (INTTYPEBITS): New macro, for clarity.
1648 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
1649 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

1663 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
1665 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
1666 instead of union.
1667 (XLI, XIL): Define.
1668 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
1669 Use them.
1670 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

1695 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
1696 * alloc.c (make_number) [!defined make_number]:

1704 USE_LSB_TAG now is always defined to be either 0 or 1.
1705 All uses changed.
1706 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
1707 code works fine either way, and efficiency is not a concern here,
1708 as the union type is for debugging, not for production.
1709 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
1710 Use an inline function on all platforms when using the union type,
1711 since this is simpler and 'static inline' can be used portably
1712 within Emacs now.
1713 (LISP_INITIALLY_ZERO): New macro.
1714 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

1743 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
1744 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
1746 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
1748 * alloc.c (make_byte_code): New function.
1749 (Fmake_byte_code): Use it. Don't purify here.

1752 2012-06-11 Chong Yidong <cyd@gnu.org>
1754 * image.c (imagemagick_load_image): Implement transparency.
1756 2012-06-10 Andreas Schwab <schwab@linux-m68k.org>

1784 dbus_type_is_basic if available.
1785 (xd_extract_signed, xd_extract_unsigned): Rename from
1786 extract_signed and extract_unsigned, respectively. Adapt callers.
1788 2012-06-09 Chong Yidong <cyd@gnu.org>

1793 case (Bug#9752).
1795 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
1797 * xdisp.c (vmessage): Treat frame message as multibyte.
1798 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
1799 would generate the diagnostic "Making \302\247 buffer-local while
1800 let-bound!".
1802 2012-06-08 Eli Zaretskii <eliz@gnu.org>
1804 * dispnew.c (showing_window_margins_p): Undo last change, which
1805 was done due to an inadvertent commit.
1806 (adjust_frame_glyphs_for_frame_redisplay): Do call
1807 showing_window_margins_p.
1809 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>

1818 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
1820 2012-06-08 Eli Zaretskii <eliz@gnu.org>
1822 * alloc.c (allocate_vectorlike): Fix last change.
1824 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
1826 Block-based vector allocation of small vectors.
1827 * lisp.h (struct vectorlike_header): New field `nbytes',
1828 adjust comment accordingly.
1829 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

1844 0 items. Allocate new vector from block if vector size is less than
1845 or equal to VBLOCK_BYTES_MAX.
1846 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
1847 (init_alloc_once): Add call to init_vectors.
1849 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
1851 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
1853 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
1855 * doprnt.c (doprnt): Truncate multibyte char correctly.
1856 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
1857 would mishandle a string argument "Xc" if X was a multibyte
1858 character of length 2: it would truncate after X's first byte
1859 rather than including all of X.
1861 2012-06-06 Chong Yidong <cyd@gnu.org>
1863 * buffer.c (word_wrap): Doc fix.
1865 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

1871 * xdisp.c (tool-bar-style): Doc fix.
1873 2012-06-03 Ulrich Müller <ulm@gentoo.org>
1875 * Makefile.in (PAXCTL): Define.
1876 (temacs$(EXEEXT)): Disable memory randomization for the temacs
1877 binary via PaX flags if the paxctl utility is available.
1878 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1879 Restore PaX flags to their default. (Bug#11398)

1888 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
1889 (note_mode_line_or_margin_highlight): If there is no help echo,
1890 use mode-line-default-help-echo. Handle the case where the mouse
1891 position is past the end of the mode line string.
1893 * buffer.c (buffer_local_value_1): New function, split from
1894 Fbuffer_local_value; can return Qunbound.
1895 (Fbuffer_local_value): Use it.
1896 (Vmode_line_format): Docstring tweaks.
1898 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

1908 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
1910 * minibuf.c (Fassoc_string): Remove duplicate declaration.
1912 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
1913 Convert pctcpu and pctmem to Lisp float properly.
1914 Let the compiler fold better, as 100.0/0x8000 is exact.
1916 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
1918 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
1919 cons_block.

1925 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
1927 For a 'struct window', replace some Lisp_Object fields to
1928 bitfields where appropriate, remove unused fields.
1929 * window.h (struct window): Remove unused 'last_mark_x' and
1930 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
1931 change it's type from Lisp_Object to bitfield.
1932 Change type of 'force_start', 'optional_new_start',
1933 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
1934 fields from Lisp_Object to bitfield. Adjust users accordingly.
1936 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
1938 Pacify gcc -Wdouble-precision when using Xaw.
1939 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
1940 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
1941 Use 'float' consistently, rather than 'float' in most places
1942 and 'double' in a couple of places.
1944 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1946 * xdisp.c (handle_stop): Detect whether we have overlay strings
1947 loaded by testing it->current.overlay_string_index to be
1948 non-negative, instead of checking whether n_overlay_strings is
1949 positive. (Bug#11587)
1951 2012-05-31 Chong Yidong <cyd@gnu.org>
1953 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
1955 * doc.c (Fsubstitute_command_keys): Doc fix.
1957 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1959 * search.c (search_buffer): Remove calls to
1960 r_alloc_inhibit_buffer_relocation, as it is now called by
1961 maybe_unify_char, which was the cause of relocation of buffer text
1962 in bug#11519.
1964 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1966 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
1967 for the duration of call to load_charset, to avoid problems with
1968 callers of maybe_unify_char that access buffer text through C
1969 pointers.
1971 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
1972 decrement the inhibition flag, instead of just setting or
1973 resetting it.
1975 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
1977 Remove obsolete '#define static' cruft.
1978 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
1979 This #undef was "temporary" in 2000; it is no longer needed
1980 now that '#define static' has gone away.
1981 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
1982 (gray_bitmap_bits): Remove; no longer needed.
1983 All uses replaced with definiens.
1984 * xterm.c: Include "bitmaps/gray.xbm".
1986 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
1988 Clean up __executable_start, monstartup when --enable-profiling.
1989 The following changes affect the code only when profiling.
1990 * dispnew.c (__executable_start): Rename from safe_bcopy.
1991 Define only on platforms that need it.
1992 * emacs.c: Include <sys/gmon.h> when profiling.
1993 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
1994 (__executable_start): Remove decl, since lisp.h does it now.
1995 (safe_bcopy): Remove decl; no longer has that name.
1996 (main): Coalesce #if into single bit of code, for simplicity.
1997 Cast pointers to uintptr_t, since standard libraries want integers
1998 and not pointers.
1999 * lisp.h (__executable_start): New decl.
2001 2012-05-31 Glenn Morris <rgm@gnu.org>
2003 * image.c (Fimagemagick_types): Doc fix.
2005 2012-05-30 Jim Meyering <meyering@redhat.com>
2007 * callproc.c (Fcall_process_region): Include directory component
2008 in mkstemp error message (Bug#11586).
2010 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

2020 (Qdefun): Move from eval.c.
2021 * lisp.h (Qdefun): Remove.
2022 * lread.c (read1): Tiny simplification.
2024 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2026 Do not create empty overlays with the evaporate property (Bug#9642).
2027 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2028 Bug#9642, but explicitly check that the buffer the overlay would
2029 be moved to is live and rearrange lines to make sure that errors
2030 will not put the overlay in an inconsistent state.
2031 (Fdelete_overlay): Cosmetics.
2033 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2035 * w32term.c (my_bring_window_to_top): New function.
2036 (x_raise_frame): Use handle returned by DeferWindowPos, which
2037 could be different from the original one.
2038 Call my_bring_window_to_top instead of my_set_foreground_window.
2039 (Bug#11513)
2041 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2042 by calling BringWindowToTop.
2044 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
2045 (WM_EMACS_END): Increase by one.
2047 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2049 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2050 This avoids undefined behavior that might cause the eassert
2051 to not catch an out-of-range value.
2053 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2055 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
2056 Update dependencies.
2058 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2060 * bidi.c (bidi_mirror_char): Fix last change.
2062 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
2064 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
2065 when referring to sectname field in printf format.
2067 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2069 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2070 Only r_alloc_inhibit_buffer_relocation needed to be added;
2071 the others were already declared.
2073 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2074 before checking whether it's out of range. Put the check inside
2075 eassert. See
2076 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2078 2012-05-27 Ken Brown <kbrown@cornell.edu>
2080 * callproc.c (Fcall_process): Restore a line that was accidentally
2081 commented out in the 2011-02-13 change (bug#11547).
2083 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2085 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2086 defined on ralloc.c.
2088 * buffer.c [REL_ALLOC]: Remove prototypes of
2089 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2090 they are now on lisp.h.
2092 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2094 * search.c (search_buffer): Use it to inhibit relocation of buffer
2095 text while re_search_2 is doing its job, because re_search_2 is
2096 passed C pointers to buffer text. (Bug#11519)
2098 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2099 Update value to 24.
2101 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2102 state after an additional call to move_it_in_display_line_to, keep
2103 the values of it->max_ascent and it->max_descent found for the
2104 entire line.
2105 (pos_visible_p): Revert the comparison against bottom_y to what it
2106 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2107 (Bug#11464)
2109 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2111 Fix coding-related core dumps with gcc -ftrapv.
2112 The code was computing A - B, where A and B are pointers, and B is
2113 random garbage. This can lead to core dumps on platforms that
2114 have special pointer registers, and it also leads to core dumps on
2115 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2116 A - B only when B is initialized properly.
2117 * coding.c (coding_set_source, coding_set_destination): Return void.
2118 (coding_change_source, coding_change_destinations): New functions,
2119 with the old behaviors of coding_set_source and coding_set_destination.
2120 All callers that need an offset changed to use these new functions.
2122 2012-05-26 Glenn Morris <rgm@gnu.org>
2124 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2126 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2128 Extend mouse support on W32 text-mode console.
2129 * xdisp.c (draw_row_with_mouse_face):
2130 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2132 * w32console.c: Include window.h.
2133 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2134 New functions.
2135 (initialize_w32_display): Initialize mouse-highlight data.
2137 * w32inevt.c: Include termchar.h and window.h.
2138 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2139 moves, call note_mouse_highlight. If help_echo changed, call
2140 gen_help_event to produce help-echo message in the echo area.
2141 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2142 highlight info.
2144 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2146 * lread.c (read1): Simplify slightly to avoid an overflow warning
2147 with GCC 4.7.0 on x86-64.
2149 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2151 * bidi.c (bidi_mirror_char): Revert last change: an int is
2152 definitely wide enough here.
2154 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2156 Fix integer width and related bugs (Bug#9874).
2157 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
2158 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
2159 (string_bytes, check_sblock, allocate_string_data):
2160 (compact_small_strings, Fmake_bool_vector, make_string)
2161 (make_unibyte_string, make_multibyte_string)
2162 (make_string_from_bytes, make_specified_string)
2163 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
2164 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2165 (mark_vectorlike):
2166 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2167 (allocate_pseudovector):
2168 Use int, not EMACS_INT, where int is wide enough.
2169 (inhibit_garbage_collection, Fgarbage_collect):
2170 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2171 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2172 int might not be wide enough.
2173 (bidi_cache_search, bidi_cache_find, bidi_init_it)
2174 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2175 (bidi_at_paragraph_end, bidi_find_paragraph_start)
2176 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2177 (bidi_level_of_next_char, bidi_move_to_visually_next):
2178 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2179 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
2180 (Fkill_buffer, Fset_buffer_major_mode)
2181 (advance_to_char_boundary, Fbuffer_swap_text)
2182 (Fset_buffer_multibyte, overlays_at, overlays_in)
2183 (overlay_touches_p, struct sortvec, record_overlay_string)
2184 (overlay_strings, recenter_overlay_lists)
2185 (adjust_overlays_for_insert, adjust_overlays_for_delete)
2186 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
2187 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
2188 (Foverlay_recenter, last_overlay_modification_hooks_used)
2189 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2190 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2191 (validate_region): Omit unnecessary test for b <= e,
2192 since that's guaranteed by the previous test.
2193 (adjust_overlays_for_delete): Avoid pos + length overflow.
2194 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2195 (report_overlay_modification):
2196 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2197 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2198 Omit pointer cast, which isn't needed anyway, and doesn't work
2199 after the EMACS_INT -> ptrdiff_t change.
2200 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2201 * buffer.h: Adjust decls to match defn changes elsewhere.
2202 (struct buffer_text, struct buffer):
2203 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2204 Use EMACS_INT, not int, where int might not be wide enough.
2205 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
2206 not int, to avoid needless 32-bit limit on 64-bit hosts.
2207 (exec_byte_code): Use tighter memory-full test, one that checks
2208 for alloca overflow. Don't compute the address of the object just
2209 before an array, as that's not portable. Use EMACS_INT, not
2210 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2211 * callint.c (Fcall_interactively):
2212 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2213 * callproc.c (call_process_kill, Fcall_process):
2214 Don't assume pid_t fits into an Emacs fixnum.
2215 (call_process_cleanup, Fcall_process, child_setup):
2216 Don't assume pid_t fits into int.
2217 (call_process_cleanup, Fcall_process, delete_temp_file)
2218 (Fcall_process_region):
2219 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2220 (Fcall_process): Simplify handling of volatile integers.
2221 Use int, not EMACS_INT, where int will do.
2222 * casefiddle.c (casify_object, casify_region, operate_on_word)
2223 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2224 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2225 (casify_object): Avoid integer overflow when overallocating buffer.
2226 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2227 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
2228 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
2229 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2230 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2231 integers are now checked earlier. All uses replaced with XINT.
2232 (ccl_driver):
2233 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2234 For CCL_MapSingle, check that content and value are in int range.
2235 (ccl_driver, Fregister_code_conversion_map):
2236 Check that Vcode_version_map_vector is a vector.
2237 (resolve_symbol_ccl_program): Check that vector header is in range.
2238 Always copy the vector, so that we can check its contents reliably
2239 now rather than having to recheck each instruction as it's being
2240 executed. Check that vector words fit in 'int'.
2241 (ccl_get_compiled_code, Fregister_ccl_program)
2242 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2243 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
2244 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
2245 contents are in range.
2246 (Fccl_execute_on_string): Check that status is in range.
2247 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2248 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2249 Accept and return EMACS_INT, not int, because callers can pass values
2250 out of 'int' range.
2251 (c_string_width, strwidth, lisp_string_width, chars_in_text)
2252 (multibyte_chars_in_text, parse_str_as_multibyte)
2253 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
2254 (str_as_unibyte, str_to_unibyte, string_count_byte8)
2255 (string_escape_byte8, Fget_byte):
2256 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2257 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2258 avoid mishandling large integers.
2259 * character.h: Adjust decls to match defn changes elsewhere.
2260 * charset.c (load_charset_map_from_file, find_charsets_in_text)
2261 (Ffind_charset_region):
2262 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2263 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
2264 (load_charset_map_from_vector, Fdefine_charset_internal):
2265 Don't assume fixnum fits in int.
2266 (load_charset_map_from_vector, Fmap_charset_chars):
2267 Remove now-unnecessary CHECK_NATNUMs.
2268 (Fdefine_charset_internal): Check ranges here, more carefully.
2269 Don't rely on undefined behavior with signed left shift overflow.
2270 Don't assume unsigned int fits into fixnum, or that fixnum fits
2271 into unsigned int. Don't require max_code to be a valid fixnum;
2272 that's not true for gb10830 4-byte on a 32-bit host. Allow
2273 invalid_code to be a cons, for the same reason. Require code_offset
2274 to be a character. Avoid int overflow if max_char is close
2275 to INT_MAX.
2276 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2277 this is intended anyway and avoids some undefined behavior.
2278 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2279 INDEX_TO_CODE_POINT, as that's what it expects.
2280 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2281 * charset.h (DECODE_CHAR): Return int, not unsigned;
2282 this is what was intended anyway, and it avoids undefined behavior.
2283 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2284 integer-overflow issues.
2285 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2286 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2287 where the argument is EMACS_INT, and this behavior is not intended.
2288 * chartab.c (Fmake_char_table, Fset_char_table_range)
2289 (uniprop_get_decoder, uniprop_get_encoder):
2290 Don't assume fixnum fits in int.
2291 * cmds.c (move_point): New function, that does the gist of
2292 Fforward_char and Fbackward_char, but does so while checking

2989 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
2990 * lisp.h (USE_LSB_TAG):
2991 * mem-limits.h (EXCEEDS_LISP_PTR):
2992 Use VAL_MAX, not VALBITS, in #if.
2993 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
2994 (EMACS_UINT): Define unconditionally now.
2995 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
2996 (BITS_PER_EMACS_INT): New constants, replacing
2997 what used to be in config.h, but not useful in #if.
2998 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
2999 define them any more.
3000 (VAL_MAX): New macro.
3001 (VALMASK): Use it.
3002 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3003 BITS_PER_EMACS_INT, in #if.
3004 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3005 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3006 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3007 * s/ms-w32.h (DATA_START):
3008 Move here from removed file m/intel386.h.
3009 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3010 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3012 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
3014 Assume C89 or later.
3015 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
3016 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
3017 (xrealloc):
3018 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
3019 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
3020 * textprop.c, tparam.c (NULL): Remove.
3021 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
3022 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
3023 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
3024 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3025 * xterm.c (input_signal_count): Assume volatile works.
3027 2012-05-21 Ken Brown <kbrown@cornell.edu>
3029 * xgselect.c (xg_select): Fix first argument in call to 'select'
3030 (bug#11508).
3032 2012-05-20 Ken Brown <kbrown@cornell.edu>
3034 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3035 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3037 2012-05-19 Ken Brown <kbrown@cornell.edu>
3039 * xfns.c (x_in_use): Remove `static' qualifier.
3040 * xterm.h (x_in_use): Declare.
3041 * xgselect.c: Include xterm.h.
3042 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3043 and `display_arg' (bug#9754).
3045 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3047 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3049 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3050 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3052 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3054 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3056 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3057 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3059 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3060 reference to image_cache->refcount.
3061 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3063 2012-05-17 Juri Linkov <juri@jurta.org>
3065 * search.c (Fword_search_regexp, Fword_search_backward)
3066 (Fword_search_forward, Fword_search_backward_lax)
3067 (Fword_search_forward_lax): Move functions to isearch.el
3068 (bug#10145, bug#11381).
3070 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3072 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3074 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3076 * lread.c (init_obarray): Declare Qt and Qnil as special.
3078 2012-05-14 Glenn Morris <rgm@gnu.org>
3080 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3081 Put "libexec" before "bin", for the sake of init_callproc_1.
3083 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3085 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3087 * unexaix.c: Port to more-recent AIX compilers.
3088 (report_error, report_error_1, make_hdr, copy_sym)
3089 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3090 Make arguments const char *, not char *, to avoid violations of C
3091 standard and to fix some AIX warnings reported by Gilles Pion.
3093 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3095 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3096 already have overlays loaded.
3097 (handle_single_display_spec): Before returning without displaying
3098 fringe bitmap, synchronize the bidi iterator with the main display
3099 iterator, by calling iterate_out_of_display_property.
3100 (iterate_out_of_display_property): Detect buffer iteration by
3101 testing that it->string is a Lisp string.
3102 (get_next_display_element): When the current object is exhausted,
3103 and there's something on it->stack, call set_iterator_to_next to
3104 proceed with what's on the stack, instead of returning zero.
3105 (set_iterator_to_next): If called at the end of a Lisp string,
3106 proceed to consider_string_end without incrementing string
3107 position. Don't increment display vector index past the end of
3108 the display vector. (Bug#11417)
3109 (pos_visible_p): Don't report a position visible when move_it_to
3110 stopped at the last line of window, which happens to be scanned
3111 backwards by the bidi iteration. (Bug#11464)
3113 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3115 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3116 and right-margin display specs even if the spec is invalid or we
3117 are on a TTY, and thus unable to display on the fringes.
3118 That's because the text with the property will not be displayed anyway,
3119 so we need to signal to the caller that this is a "replacing"
3120 display spec. This fixes display when the spec is invalid or we
3121 are on a TTY.
3123 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3125 * unexaix.c (make_hdr): Fix typo in prototype.
3126 This bug broke the build on AIX. Problem reported by Gilles Pion.
3128 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3130 * keyboard.c (kbd_buffer_get_event): Read special events also in
3131 batch mode. (Bug#11415)
3133 2012-05-12 Glenn Morris <rgm@gnu.org>
3135 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3137 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3139 * lisp.mk (lisp): Add newcomment.elc.
3141 2012-05-12 Glenn Morris <rgm@gnu.org>
3143 * Makefile.in (MKDIR_P): New, set by configure.
3144 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3146 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3148 Remove unused function hourglass_started.
3149 * dispextern.h (hourglass_started):
3150 * w32fns.c (hourglass_started):
3151 * xdisp.c (hourglass_started): Remove.
3153 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3155 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3156 Update dependencies.
3158 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3160 * xgselect.c (xg_select): Put maxfds+1 into a var.
3161 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3163 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3165 2012-05-10 Dave Abrahams <dave@boostpro.com>
3167 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3168 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3170 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3172 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3173 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3174 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3175 Initialize xd_registered_buses.
3177 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3179 Untag more efficiently if USE_LSB_TAG.
3180 This is based on a proposal by YAMAMOTO Mitsuharu in
3181 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3182 For an admittedly artificial (nth 8000 longlist) benchmark on
3183 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3184 Emacs's overall text size by 1%.
3185 * lisp.h (XUNTAG): New macro.
3186 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3187 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3188 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3189 * eval.c (Fautoload):
3190 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3191 * frame.h (XFRAME): Use XUNTAG.
3193 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3194 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3195 Remove unportable assumptions about print widths of types like
3196 dbus_uint32_t.
3197 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3198 intptr_t when converting between pointer and integer, to avoid GCC
3199 warnings about wrong width.
3201 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3203 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3204 stack for each reader_thread, instead of defaulting to 8MB
3205 determined by the linker. This avoids failures in creating
3206 subprocesses on Windows 7, see the discussion in this thread:
3207 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3209 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3211 Fix up display of the *Minibuf-0* buffer in the mini window.
3212 * keyboard.c (read_char): Don't clear the echo area if there's no
3213 message to clear.
3214 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3215 contents of *Minibuf-0*) if there's no message displayed in its stead.
3217 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3219 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3220 batch mode.
3222 2012-05-06 Chong Yidong <cyd@gnu.org>
3224 * lisp.mk (lisp): Update.
3226 2012-05-05 Jim Meyering <meyering@redhat.com>
3228 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3230 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3232 * data.c (PUT_ERROR): New macro.
3233 (syms_of_data): Use it. Add new error type `user-error'.
3234 * undo.c (user_error): New function.
3235 (Fprimitive_undo): Use it.
3236 * print.c (print_error_message): Adjust print style for `user-error'.
3237 * keyboard.c (user_error): New function.
3238 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3240 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3242 Do not limit current-time-string to years 1000..9999.
3243 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3244 (Fcurrent_time_string): Support any year that is supported by the
3245 underlying localtime representation. Don't use asctime, as it
3246 has undefined behavior for years outside the range -999..9999.
3248 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3250 Fix race conditions involving setenv, gmtime, localtime, asctime.
3251 Without this fix, interrupts could mess up code that uses these
3252 nonreentrant functions, since setting TZ invalidates existing
3253 tm_zone or tzname values, and since most of these functions return
3254 pointers to static storage.
3255 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3256 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3257 Grow the critical sections to include not just invoking
3258 localtime/gmtime, but also accessing these functions' results
3259 including their tm_zone values if any, and any related TZ setting.
3260 (format_time_string): Last arg is now struct tm *, not struct tm **,
3261 so that the struct tm is saved in the critical section.
3262 All callers changed. Simplify allocation of initial buffer, partly
3263 motivated by the fact that memory allocation needs to be outside
3264 the critical section.
3266 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3268 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3269 with RESET_INTERVAL.
3271 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3272 Remove duplicated buffer name initialization.
3274 2012-05-02 Jim Meyering <jim@meyering.net>
3276 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3278 * xfns.c (x_window): Use xstrdup (Bug#11375).
3280 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3282 * xdisp.c (pos_visible_p): If already at a newline from the
3283 display string before the 'while' loop, don't walk back the glyphs
3284 from it3.glyph_row. Solves assertion violation when the display
3285 string begins with a newline (egg.el). (Bug#11367)
3287 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3289 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3290 Move to simple.el.
3292 2012-05-01 Glenn Morris <rgm@gnu.org>
3294 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3295 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3296 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3297 All were removed before 23.1.
3299 * dispnew.c: Remove HAVE_LIBNCURSES test;
3300 it is always true on relevant platforms.
3302 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3303 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3305 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3307 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3309 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3310 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3311 Remove.
3313 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3315 Do not avoid creating empty evaporating overlays (Bug#9642).
3316 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3317 That is, do not delete an evaporating overlay if it becomes
3318 empty after its bounds are adjusted to fit within its buffer.
3319 This fix caused other problems, and I'm reverting it until we get
3320 to the bottom of them.
3322 2012-04-27 Chong Yidong <cyd@gnu.org>
3324 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3326 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3328 * xdisp.c (pos_visible_p): If the window start position is beyond
3329 ZV, start the display from buffer beginning. Prevents assertion
3330 violation in init_iterator when the minibuffer window is scrolled
3331 via the scroll bar.
3333 * window.c (window_scroll_pixel_based): Likewise.
3335 2012-04-27 Chong Yidong <cyd@gnu.org>
3337 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3339 2012-04-27 Glenn Morris <rgm@gnu.org>
3341 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3342 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3344 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3346 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3347 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3349 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3351 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3352 display element, check also the underlying string or buffer
3353 character. (Bug#11341)
3355 * w32menu.c: Include w32heap.h.
3356 (add_menu_item): If the call to AppendMenuW (via
3357 unicode_append_menu) fails, disable Unicode menus only if we are
3358 running on Windows 9X/Me.
3360 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3362 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3363 (xgetint): Add missing shift for LSB tags.
3365 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3367 * keyboard.c (read_char): Don't wipe echo area for select window
3368 events: These might get delayed via `mouse-autoselect-window'
3369 (Bug#11304).
3371 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3373 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3374 manipulation of :loaded-from data.
3376 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3378 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3379 now a cons (bug#11311).
3381 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3383 Do not create empty overlays with the evaporate property (Bug#9642).
3384 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3385 if it becomes empty after its bounds are adjusted to fit within
3386 its buffer. Without this fix, in a nonempty buffer (let ((o
3387 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3388 yields an empty overlay that has the evaporate property, which is
3389 not supposed to happen.
3391 Fix minor GTK3 problems found by static checking.
3392 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3393 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3394 (struct _EmacsFixedClass, emacs_fixed_get_type):
3395 Move decls here from emacsgtkfixed.h, since they needn't be public.
3396 (emacs_fixed_get_type): Now static.
3397 (emacs_fixed_class_init): Omit unused local.
3398 (emacs_fixed_child_type): Remove; unused.
3399 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3400 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3401 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
3402 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
3403 (EMACS_FIXED_GET_CLASS): Remove; unused.
3404 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
3406 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
3407 Problem reported by Juanma Barranquero for Windows -Wunused-function.
3409 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3411 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
3412 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
3413 (__malloc_size_t, __malloc_ptrdiff_t):
3414 Remove. All uses removed, replaced by the definiens if needed,
3415 since we can assume C89 or better now.
3416 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
3417 (protect_malloc_state, align, get_contiguous_space)
3418 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
3419 (malloc_atfork_handler_child, malloc_enable_thread)
3420 (malloc_initialize_1, __malloc_initialize, morecore_nolock)
3421 (_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
3422 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
3423 (special_realloc, _realloc_internal_nolock, _realloc_internal)
3424 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
3425 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
3426 Define using prototypes, not old style.
3427 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
3428 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
3429 (align): Don't assume that signed integer overflow wraps around.
3430 Omit unused local var.
3431 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
3432 (_free_internal_nolock, memalign, mallochook, reallochook):

3493 since the two debugging options are incompatible.
3494 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
3495 is defined.
3496 (mem_init, mem_insert, mem_insert_fixup):
3497 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
3498 (NEED_MEM_INSERT): Remove; no longer needed.
3500 2012-04-22 Leo Liu <sdl.web@gmail.com>

3532 2012-04-20 Chong Yidong <cyd@gnu.org>
3534 * process.c (wait_reading_process_output): If EIO occurs on a pty,
3535 set the status to "failed" and ensure that sentinel is run.

3590 New extern decls, to avoid calling undeclared functions.
3591 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
3592 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3593 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
3594 (NEED_MEM_INSERT): New macro.
3595 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

3610 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
3611 Remove decls. This fixes an "It stinks!".

3615 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
3617 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

3628 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
3630 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
3631 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
3632 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
3633 * s/netbsd.h, s/sol2-6.h:
3634 Remove definition of GC_MARK_STACK, since the default now works.
3635 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
3636 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
3637 no longer the default.
3638 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
3640 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

3663 2012-04-11 Daniel Colascione <dancol@dancol.org>
3665 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3666 against is gone. It's better to use vfork now so that when Cygwin
3667 gains a new, working vfork, we use it automatically (bug#10398).
3669 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
3671 * window.c (save_window_save): Obey window-point-insertion-type.

3690 being loaded (bug#10424).
3692 2012-04-09 Glenn Morris <rgm@gnu.org>
3694 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
3695 not just in the obarray, before snarfing them. (Bug#11036)

3713 attempts per process (connection).
3715 2012-04-09 Chong Yidong <cyd@gnu.org>
3717 * eval.c (Fuser_variable_p, user_variable_p_eh)

3722 * minibuf.c (Fread_variable): Callers changed.
3724 2012-04-09 Eli Zaretskii <eliz@gnu.org>
3726 * xdisp.c (set_cursor_from_row): If the display string appears in
3727 the buffer at position that is closer to point than the position
3728 after the display string, display the cursor on the first glyph of
3729 the display string. Fixes cursor display when a 'display' text
3730 property immediately follows invisible text. (Bug#11094)
3732 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
3734 composite.c: use 'double' consistently
3735 * composite.c (get_composition_id): Use 'double' consistently
3736 instead of converting 'float' to 'double' and vice versa; this is
3737 easier to understand and avoids a GCC warning.
3739 2012-04-09 Glenn Morris <rgm@gnu.org>
3741 * Makefile.in: Generate leim-list with bootstrap-emacs, in

3784 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
3785 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
3786 [!WINDOWSNT]: New macros.
3787 (init_libxml2_functions, libxml2_loaded_p): New functions.
3788 (parse_region): Call fn_xmlCheckVersion instead of using the macro
3789 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
3790 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
3791 Calls xmlCleanupParser only if libxml2 was loaded (or statically
3792 linked in).
3793 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
3794 Call init_libxml2_functions before calling libxml2 functions.
3795 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
3797 * emacs.c: Don't include libxml/parser.h.
3798 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
3799 xmlCleanupParser directly.
3801 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
3803 2012-04-07 Eli Zaretskii <eliz@gnu.org>
3805 * indent.c (Fvertical_motion): If there is a display string at
3806 point, use it.vpos to compute how many lines to backtrack after
3807 move_it_to point. (Bug#11133)
3809 2012-04-06 Eli Zaretskii <eliz@gnu.org>
3811 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
3812 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
3813 about subtle differences between FETCH_CHAR* and STRING_CHAR*
3814 macros related to unification of CJK characters. For the details,
3815 see the discussion following the message here:
3816 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
3818 2012-04-04 Chong Yidong <cyd@gnu.org>

3832 2012-03-31 Eli Zaretskii <eliz@gnu.org>
3834 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
3835 position we get to after a call to move_it_to fails the
3836 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
3837 only if we wind up in a string from display property. (Bug#11063)
3839 * window.c (Fdelete_other_windows_internal): Invalidate the row
3840 and column information about mouse highlight, so that redisplay
3841 restores it after reallocating the glyph matrices. (Bug#7464)
3843 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
3844 string comes from a `display' text property, use the buffer
3845 position of that property as if we actually saw that position in
3846 the row's glyphs.
3847 (move_it_by_lines): Remove the assertion that
3848 "it->current_x == 0 && it->hpos == 0" which can be legitimately
3849 violated when there's a before-string at the beginning of a line.
3850 (Bug#11063)
3852 2012-03-30 Eli Zaretskii <eliz@gnu.org>
3854 * xdisp.c (append_space_for_newline): If the default face was
3855 remapped, use the remapped face for the appended newline.
3856 (extend_face_to_end_of_line): Use the remapped default face for
3857 extending the face to the end of the line.
3858 (display_line): Call extend_face_to_end_of_line when the default
3859 face was remapped. (Bug#11068)
3861 2012-03-29 Eli Zaretskii <eliz@gnu.org>

3881 * keyboard.c (Vselection_inhibit_update_commands): New variable.
3882 (command_loop_1): Use it; inhibit selection update for

3889 2012-03-25 Kenichi Handa <handa@m17n.org>
3891 * dispextern.h (struct glyph): Change the bit length of
3892 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
3894 2012-03-24 Eli Zaretskii <eliz@gnu.org>
3896 * s/ms-w32.h (tzname): Include time.h before redirecting to
3897 _tzname. Fixes the MSVC build. (Bug#9960)
3899 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
3901 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
3902 characters.
3904 * xterm.c (XTread_socket): Only modify handling_signal if
3905 !SYNC_INPUT. (Bug#11080)
3907 2012-03-23 Eli Zaretskii <eliz@gnu.org>
3909 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
3910 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
3911 when fetching a multibyte character consumes more bytes than
3912 CHAR_BYTES returns, due to unification of CJK characters in
3913 string_char. (Bug#11073)
3915 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
3917 * process.c (wait_reading_process_output): Handle pty disconnect
3918 by refraining from sending oneself a SIGCHLD (bug#10933).

3924 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
3925 Mark string as coming from a prefix property.
3926 (handle_face_prop): Use default face for prefix strings (Bug#4281).

3929 2012-03-21 Chong Yidong <cyd@gnu.org>
3931 * xfaces.c (Vface_remapping_alist): Doc fix.
3933 2012-03-20 Eli Zaretskii <eliz@gnu.org>
3935 * w32proc.c (Fw32_set_console_codepage)
3936 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
3937 Doc fixes.
3939 2012-03-20 Chong Yidong <cyd@gnu.org>
3941 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
3942 to reflect default non-nil value of redisplay-dont-pause.
3944 2012-03-19 Kenichi Handa <handa@m17n.org>
3946 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
3947 it fit in a valid range (Bug#11003).
3949 2012-03-18 Eli Zaretskii <eliz@gnu.org>
3951 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
3952 that is not from display property, accept the row as a "cursor
3953 row" if one of the string's character has a non-nil `cursor'
3954 property. Fixes cursor positioning when there are newlines in
3955 overlay strings, e.g. in icomplete.el. (Bug#11035)
3957 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
3959 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
3961 2012-03-12 Chong Yidong <cyd@gnu.org>
3963 * eval.c (inhibit_lisp_code): Rename from
3964 inhibit_window_configuration_change_hook; move from window.c.
3966 * xfns.c (unwind_create_frame_1, Fx_create_frame):
3967 * window.c (run_window_configuration_change_hook)
3968 (syms_of_window): Callers changed.
3970 2012-03-11 Chong Yidong <cyd@gnu.org>
3972 * keymap.c (Fkey_description): Doc fix (Bug#9700).

3979 is visible (Bug#10955).
3981 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
3983 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
3985 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
3987 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
3988 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
3989 zero (Bug#10954).
3991 2012-03-03 Glenn Morris <rgm@gnu.org>
3993 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
3995 2012-03-02 Eli Zaretskii <eliz@gnu.org>
3997 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
3998 position past the first glyph_row that ends at ZV. (Bug#10902)
3999 (redisplay_window, next_element_from_string): Fix typos in
4000 comments.
4001 (redisplay_window): Pass to move_it_vertically the margin in
4002 pixels, not in screen lines.
4004 2012-03-02 Glenn Morris <rgm@gnu.org>
4006 * buffer.c (buffer-list-update-hook): Doc fix.
4008 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4010 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4011 push_it before setting up the iterator for the first overlay
4012 string, even if we have an empty string loaded.
4013 (next_overlay_string): If there's an empty string on the iterator
4014 stack, pop the stack. (Bug#10903)
4016 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4018 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4019 Suggested by Stefan Monnier in
4020 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4021 * alloc.c (widen_to_Lisp_Object): New static function.
4022 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4023 and widening them to Lisp_Objects. This would work even if
4024 USE_LSB_TAG is defined and wide integers are used, which might
4025 happen in a future version of Emacs.
4027 2012-02-25 Chong Yidong <cyd@gnu.org>
4029 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4030 Doc fix.
4032 * xselect.c (Fx_selection_exists_p): Doc fix.
4033 (x_clipboard_manager_save_all): Print an informative message
4034 before saving to clipboard manager.
4036 2012-02-24 Chong Yidong <cyd@gnu.org>
4038 * keyboard.c (process_special_events): Handle all X selection
4039 requests in kbd_buffer, not just the next one (Bug#8869).
4041 2012-02-23 Chong Yidong <cyd@gnu.org>
4043 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4044 call when setting menu-bar-lines and tool-bar-lines parameters.
4045 (unwind_create_frame_1): New helper function.
4047 * window.c (inhibit_window_configuration_change_hook): New var.
4048 (run_window_configuration_change_hook): Obey it.
4049 (syms_of_window): Initialize it.
4051 2012-02-22 Chong Yidong <cyd@gnu.org>
4053 * xterm.c (x_draw_image_relief): Add missing type check for
4054 Vtool_bar_button_margin (Bug#10743).
4056 2012-02-21 Chong Yidong <cyd@gnu.org>
4058 * fileio.c (Vfile_name_handler_alist): Doc fix.
4060 * buffer.c (Fget_file_buffer): Protect against invalid file
4061 handler return value.
4063 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
4065 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4066 when computing $valmask.
4068 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4069 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4070 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4071 It's useless in that case, and it can cause problems on hosts
4072 that allocate halves of EMACS_INT values separately.
4073 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4074 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4075 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4076 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4077 it avoids undefined behavior on hosts where shifting right by more
4078 than the word width has undefined behavior.
4080 2012-02-19 Chong Yidong <cyd@gnu.org>
4082 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4083 (Funhandled_file_name_directory, Ffile_name_as_directory)
4084 (Fdirectory_file_name, Fexpand_file_name)
4085 (Fsubstitute_in_file_name): Protect against invalid file handler
4086 return values (Bug#10845).
4088 2012-02-18 Eli Zaretskii <eliz@gnu.org>

4100 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
4102 2012-02-15 Chong Yidong <cyd@gnu.org>
4104 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4105 marked as special. Also, starting docstrings with * is obsolete.

4109 * gnutls.c (emacs_gnutls_write): Fix last change.
4111 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

4116 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
4118 * keymap.c (Fsingle_key_description): Handle char ranges.
4120 2012-02-12 Chong Yidong <cyd@gnu.org>
4122 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
4123 as that creates a dangerous corner case.
4125 * window.c (Fdelete_window_internal): Invalidate the mouse
4126 highlight (Bug#9904).
4128 2012-02-12 Glenn Morris <rgm@gnu.org>
4130 * xselect.c (Fx_own_selection_internal)
4131 (Fx_get_selection_internal, Fx_disown_selection_internal)
4132 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
4133 * nsselect.m (Fx_own_selection_internal)
4134 (Fx_disown_selection_internal, Fx_selection_exists_p)
4135 (Fx_selection_owner_p, Fx_get_selection_internal):
4136 Sync docs and argument specs with the xselect.c versions.
4138 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
4140 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

4158 2012-02-07 Chong Yidong <cyd@gnu.org>
4160 * buffer.c (Fbuffer_local_variables)
4161 (buffer_lisp_local_variables): Handle unbound vars correctly;
4162 don't let Qunbound leak into Lisp.
4164 2012-02-07 Glenn Morris <rgm@gnu.org>
4166 * image.c (Fimagemagick_types): Doc fix.
4168 * image.c (imagemagick-render-type): Change it from a lisp object
4169 to an integer. Move the doc here from the lisp manual.

4177 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
4179 * .gdbinit (pp1, pv1): Remove redundant defines.
4180 (pr): Use pp.
4182 2012-02-04 Chong Yidong <cyd@gnu.org>
4184 * nsterm.m: Declare a global (Bug#10694).
4186 2012-02-04 Eli Zaretskii <eliz@gnu.org>
4188 * w32.c (get_emacs_configuration_options):
4189 Include --enable-checking, if specified, in the return value.

4193 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
4194 after rounding frame sizes. (Bug#9723)
4196 2012-02-04 Eli Zaretskii <eliz@gnu.org>

4199 before BEGV. (Bug#10696)
4201 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
4203 Handle overflow when computing char display width (Bug#9496).
4204 * character.c (char_width): Return EMACS_INT, not int.
4205 (char_width, c_string_width): Check for overflow when
4206 computing the width; this is possible now that individual
4207 characters can have unbounded width. Problem introduced
4208 by merge from Emacs 23 on 2012-01-19.
4210 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
4212 * dbusbind.c (Fdbus_register_method): Mention the return value

4225 2012-02-02 Kenichi Handa <handa@m17n.org>
4227 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
4228 0, do not call append_composite_glyph.

4232 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
4233 NULL (Bug#6988).

4239 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
4240 first 2 arguments are identical. This makes inserting large
4241 output from a subprocess an order of magnitude faster on
4242 MS-Windows, where all sbrk'ed memory is always contiguous.
4244 2012-01-31 Glenn Morris <rgm@gnu.org>
4246 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

4282 2012-01-21 Chong Yidong <cyd@gnu.org>
4284 * floatfns.c (Fcopysign): Make the second argument non-optional,
4285 since nil is not allowed anyway.
4287 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>

4300 * character.c (char_width): New function.
4301 (Fchar_width, c_string_width, lisp_string_width):
4302 Use char_width (Bug#9496).
4304 2012-01-16 Martin Rudalics <rudalics@gmx.at>
4306 * window.c (Vwindow_persistent_parameters): New variable.
4307 (Fset_window_configuration, save_window_save): Handle persistent
4308 window parameters.
4310 2012-01-14 Eli Zaretskii <eliz@gnu.org>
4312 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid

4325 before a R2L line.
4327 2012-01-11 Glenn Morris <rgm@gnu.org>
4329 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
4330 from load-path also when installation-directory is nil. (Bug#10208)
4332 2012-01-10 Glenn Morris <rgm@gnu.org>
4334 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
4336 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
4337 Update template values to be closer to their typical values these days.
4339 2012-01-09 Eli Zaretskii <eliz@gnu.org>
4341 * xdisp.c (rows_from_pos_range): Accept additional argument
4342 DISP_STRING, and accept any glyph in a row whose object is that
4343 string as eligible for mouse highlight. Fixes mouse highlight of
4344 display strings from overlays. (Bug#10464)
4346 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
4348 emacs: fix an auto-save permissions race condition (Bug#10400)
4349 * fileio.c (auto_saving_dir_umask): New static var.
4350 (Fmake_directory_internal): Use it.
4351 (do_auto_save_make_dir): Set it, instead of invoking chmod after
4352 creating the directory. The old code temporarily assigns
4353 too-generous permissions to the directory.
4354 (do_auto_save_eh): Clear it.
4355 (Fdo_auto_save): Catch all errors, not just file errors, so
4356 that the var is always cleared.
4358 2012-01-07 Eli Zaretskii <eliz@gnu.org>
4360 * search.c (scan_buffer): Pass character positions to
4361 know_region_cache, not byte positions. (Bug#6540)
4363 2012-01-07 LynX <_LynX@bk.ru> (tiny change)
4365 * w32.c (sys_rename): Report EXDEV when rename of a directory

4864 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
4865 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
4866 to 4 (xorl, subq, cmpq, setbe).
4867 * alloc.c (pure): Always extern now, since that's the
4868 VIRT_ADDR_VARIES behavior.
4869 (PURE_POINTER_P): Use a single comparison, not two, for
4870 consistency with the new puresize.h.
4871 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
4872 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

4880 behave as if the cursor position were at the window margin.
4882 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
4883 and the cursor position is out of bounds, behave as if the cursor
4884 position were at the window margin. (Bug#10075)
4886 2011-11-18 Chong Yidong <cyd@gnu.org>
4888 * window.c (Fwindow_combination_limit): Make first argument

4912 hash code inline.
4914 * dispnew.c (verify_row_hash): Call row_hash for computing the
4915 hash code of a row, instead of duplicating code from xdisp.c.

4955 2011-11-14 Eli Zaretskii <eliz@gnu.org>
4957 * xdisp.c (display_line): Move the call to
4958 highlight_trailing_whitespace before the call to
4959 compute_line_metrics, since the latter needs to see the final
4960 faces of all the glyphs to compute ROW's hash value.
4961 Fixes assertion violations in row_equal_p. (Bug#10035)
4963 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
4965 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

4970 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
4971 with user-defined heap size. Bump the default size of the temacs
4972 heap to 27MB, to avoid memory warning when running temacs.
4973 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
4975 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

5022 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
5024 Avoid some portability problems by eschewing 'extern inline' functions.
5025 The trivial performance wins aren't worth the portability hassles; see

5031 by removing the "extern"s.
5032 * intervals.c (adjust_intervals_for_insertion)
5033 (adjust_intervals_for_deletion): Undo previous change,
5034 making these static again.
5035 (offset_intervals, temp_set_point_both, temp_set_point)
5036 (copy_intervals_to_string): No longer inline.

5103 (window_box_right, window_box_right_offset): Declare extern.
5104 Otherwise, these inline functions do not conform to C99 and
5105 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5106 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5107 * intervals.c (adjust_intervals_for_insertion)

5110 (static_offset_intervals): Remove.
5111 (offset_intervals): Rewrite using the old contents of
5112 static_offset_intervals. The old version didn't conform to C99
5113 because an extern inline function contained a reference to an
5114 identifier with static linkage.

5322 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
5324 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
5326 * window.c (make_window): Initialize phys_cursor_on_p.
5328 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5330 * lisp.h (struct Lisp_Symbol): Update comments.
5332 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
5334 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
5336 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5338 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
5339 <oslsachem@gmail.com> for helping to debug this.
5341 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
5342 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
5343 (g_b_init_get_glyph_outline_w): New static variables.
5344 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
5345 (GetGlyphOutlineW_Proc): New typedefs.
5346 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
5347 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
5348 New functions.
5349 (w32font_open_internal, compute_metrics):
5350 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
5351 instead of calling the "wide" APIs directly.
5353 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
5355 * w32.h (syms_of_w32font): Add prototype.
5357 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5359 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
5360 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
5361 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
5362 (Fmove_to_window_line): Doc fix.
5364 2011-10-27 Chong Yidong <cyd@gnu.org>
5366 * process.c (make_process): Set gnutls_state to NULL.
5368 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
5369 non-NULL, regardless of GNUTLS_INITSTAGE.
5370 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
5371 an error. Set process slots as soon as we allocate them.
5373 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
5375 2011-10-27 Chong Yidong <cyd@gnu.org>
5377 * gnutls.c (emacs_gnutls_deinit): New function.
5378 Deallocate credentials structures as well as calling gnutls_deinit.
5379 (Fgnutls_deinit, Fgnutls_boot): Use it.
5381 * process.c (make_process): Initialize GnuTLS credentials to NULL.
5382 (deactivate_process): Call emacs_gnutls_deinit.
5384 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5386 * image.c (x_create_x_image_and_pixmap):
5387 * w32.c (sys_rename, w32_delayed_load):
5388 * w32font.c (fill_in_logfont):
5389 * w32reg.c (x_get_string_resource): Silence compiler warnings.
5391 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
5393 * w32fns.c (w32_default_color_map): New function,
5394 extracted from Fw32_default_color_map.
5395 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
5397 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
5399 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
5401 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
5403 * keyboard.c (test_undefined): New function (bug#9751).
5404 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
5406 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
5408 * sysdep.c (init_sys_modes): Fix the check for the controlling
5409 terminal (Bug#6649).
5411 2011-10-20 Eli Zaretskii <eliz@gnu.org>
5413 * dispextern.h (struct bidi_it): New member next_en_type.
5415 * bidi.c (bidi_line_init): Initialize the next_en_type member.
5416 (bidi_resolve_explicit_1): When next_en_pos is valid for the
5417 current character, check also for next_en_type being WEAK_EN.
5418 (bidi_resolve_weak): Don't enter the expensive loop if the current
5419 position is before next_en_pos. Record the bidi type of the first
5420 non-ET, non-BN character we find, in addition to its position.
5421 (bidi_level_of_next_char): Invalidate next_en_type when
5422 next_en_pos is over-stepped.
5424 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
5426 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5427 * editfns.c: Rewrite current-time-zone so that it invokes
5428 the equivalent of (format-time-string "%Z") to get the time zone name.
5429 This fixes a bug when the time zone name contains characters that
5430 need converting from the system time locale to Emacs internal format.
5431 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5432 that patch fixed format-time-string to do the conversion, but
5433 I forgot to fix current-time-zone.
5434 (format_time_string): New function, containing most of
5435 what Fformat_time_string used to contain.
5436 (Fformat_time_string): Rewrite in terms of format_time_string.
5437 This doesn't change this function's behavior.
5438 (current-time-zone): Rewrite to use format_time_string.
5439 This fixes the bug reported by Michael Schierl in
5440 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5441 Jason Rumney's 2007-06-07 change worked around this bug, but
5442 didn't fix it.
5443 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5445 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5447 * xdisp.c (start_display): If the character at POS is displayed
5448 via a display vector, reset IT->current.dpvec_index to zero.
5449 (try_window_reusing_current_matrix): If a line ends in a display
5450 vector or the next line starts in a display vector, continue
5451 redrawing the window even though the character position of
5452 start_row was reached.
5453 (Bug#9771, part 2)
5455 2011-10-18 Chong Yidong <cyd@gnu.org>
5457 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5458 with nobreak-char-display too.
5460 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5462 Fix part 3 of bug#9771.
5463 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5464 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5465 non-neutral characters if the current character is a paragraph
5466 separator (a.k.a. Newline). This avoids running the same
5467 expensive loop twice, once when we consume the preceding newline
5468 and the other time when the line actually needs to be displayed.
5469 Avoid the loop when we see neutrals on the base embedding level
5470 following a character whose directionality is the same as the
5471 paragraph's. This avoids running the expensive loop when a line
5472 ends in a long sequence of neutrals, like control characters.
5473 Add assertion against STRONG_AL type. Slightly rearrange code
5474 that determines the type of a neutral given the first non-neutral
5475 that follows it.
5476 (bidi_level_of_next_char): Set next_en_pos to zero when
5477 invalidating its info.
5479 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5481 * xdisp.c (push_display_prop): Determine whether to record string
5482 or buffer position by IT->string, not by IT->method. Allow
5483 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5484 (move_it_vertically_backward): Don't look for character position
5485 immediately after the newline when in a continuation line.
5486 (Bug#9771, part 1)
5488 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5490 * window.c (coordinates_in_window): Rewrite and delabelize
5491 vertical border check. (Bug#5357) (Bug#9618)
5493 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5495 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5496 errors in XSetWindowBorder (bug#9310).
5498 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5500 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5501 avoid crash when xmalloc overrun checking is enabled.
5503 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5505 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5506 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5507 cursor motion with <left> and <right> arrow keys.
5509 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5510 some callers set that themselves.
5512 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5514 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5515 display string and the previous row comes from the same string and
5516 is empty. (Bug#9739) (Bug#9738)
5518 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5520 * doc.c (get_doc_string): Encode file name (bug#9735).
5522 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5524 * bidi.c (bidi_level_of_next_char):
5525 * xdisp.c (get_visually_first_element): Remove old incorrect
5526 comments regarding the Unicode Line Separator character.
5528 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5530 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5532 * alloc.c (Fgc_status): Do not access beyond zombies array
5533 boundary if nzombies > MAX_ZOMBIES.
5534 * alloc.c (dump_zombies): Add missing format specifier.
5536 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5538 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5539 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5541 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5542 Some packages use them to denote characters with modifiers.
5544 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5546 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5547 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5548 matching a pp-number. Rename parameter var to var1.
5550 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5552 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5554 2011-10-08 Glenn Morris <rgm@gnu.org>
5556 * callint.c (Fcall_interactively): Give a more explicit error for the
5557 'c' case with a non-character input. (Bug#8479)
5559 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5561 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5562 lines.
5563 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5564 lines that are hscrolled on the left.
5566 * dispnew.c (buffer_posn_from_coords): Account for a possible
5567 presence of header-line. (Bug#4426)
5569 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5571 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5572 Don't advertise functionality which we discourage or doesn't work.
5574 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5576 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5577 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5578 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5579 this makes Emacs dump core during garbage collection on rare
5580 occasions. sizeof is obviously inferior to offsetof here, so
5581 stick with offsetof.
5582 (GC_POINTER_ALIGNMENT): New macro.
5583 (mark_memory): Omit 3rd (offset) arg; caller changed.
5584 Don't assume EMACS_INT alignment is the same as pointer alignment.
5586 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5588 * keyboard.c (read_key_sequence_remapped): New var.
5589 (read_key_sequence): Compute remapping in the right buffer.
5590 (command_loop_1): Use read_key_sequence's remapping directly.
5592 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5594 * dired.c (file_name_completion): Don't expand file name.
5595 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5596 before checking file name handler.
5598 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5599 they've been requested explicitly (bug#9591).
5601 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5603 * keymap.c (Fsingle_key_description): Use make_specified_string
5604 instead of build_string to build string from push_key_description.
5605 (Bug#5193)
5607 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5609 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5610 This fixes a Y2038 bug on 64-bit hosts.
5611 * buffer.c (reset_buffer):
5612 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5613 (Fclear_buffer_auto_save_failure):
5614 Use 0, not -1, to represent an unset failure time, since time_t
5615 might not be signed.
5617 Remove dependency on glibc malloc internals.
5618 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5619 Move back here from lisp.h, but with their new implementations.
5620 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5621 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5622 * charset.c (charset_table_init): New static var.
5623 (syms_of_charset): Use it instead of xmalloc. This removes a
5624 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5625 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
5626 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5627 Move back to alloc.c.
5628 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5629 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
5631 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
5633 * nsterm.m (windowDidResize): Call x_set_window_size only when
5634 ns_in_resize is true. Otherwise set pixelwidth/height and
5635 call change_frame_size (Bug#9628).
5637 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5639 Port --enable-checking=all to Fedora 14 x86-64.
5640 * charset.c (syms_of_charset): Also account for glibc malloc's
5641 internal overhead when calculating the initial malloc maximum.
5643 Port --enable-checking=all to Fedora 14 x86.
5644 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5645 Move to lisp.h.
5646 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5647 (overrun_check_realloc, overrun_check_free):
5648 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5649 That way, xmalloc returns a properly-aligned pointer even if
5650 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
5651 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5652 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5653 into account when calculating the initial malloc maximum.
5654 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5655 Move here from alloc.c, so that charset.c can use it too.
5656 Properly align; the old code wasn't right for common 32-bit hosts
5657 when configured with --enable-checking=all.
5658 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5659 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
5661 2011-09-29 Eli Zaretskii <eliz@gnu.org>
5663 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
5664 use EDOM.
5666 2011-09-28 Eli Zaretskii <eliz@gnu.org>
5668 * xdisp.c (compute_display_string_end): If there's no display
5669 string at CHARPOS, return -1.
5671 * bidi.c (bidi_fetch_char): When compute_display_string_end
5672 returns a negative value, treat the character as a normal
5673 character not covered by a display string. (Bug#9624)
5675 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
5677 * lread.c (Fread_from_string): Fix typo in docstring.
5679 2011-09-27 Eli Zaretskii <eliz@gnu.org>
5681 * xdisp.c (handle_invisible_prop): If invisible text ends on a
5682 newline, reseat the iterator instead of bidi-iterating there one
5683 character at a time. (Bug#9610)
5684 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
5685 TO_CHARPOS if the bidi iterator is at base embedding level.
5687 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
5689 * lread.c (readevalloop): Use correct code for NBSP.
5690 (read1): Likewise. (Bug#9608)
5692 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
5694 * dbusbind.c (Fdbus_register_signal): When service is not
5695 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
5697 2011-09-25 Glenn Morris <rgm@gnu.org>
5699 * buffer.c (truncate-lines): Doc fix.
5701 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
5703 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
5704 (Fset_window_next_buffers): Doc fix.
5706 2011-09-24 Glenn Morris <rgm@gnu.org>
5708 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
5710 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
5712 Fix minor problems found by static checking.
5713 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
5714 * indent.c (Fvertical_motion): Fix == vs = typo.
5716 2011-09-24 Eli Zaretskii <eliz@gnu.org>
5718 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
5719 Default value is now t. Doc fix.
5721 * indent.c (Fvertical_motion): Compute and apply the overshoot
5722 logic when moving up, not only when moving down. Fix the
5723 confusing name and values of the it_overshoot_expected variable;
5724 logic changes accordingly. (Bug#9254) (Bug#9549)
5726 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
5727 CHARPOS is covered by a display string which includes newlines.
5728 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
5729 is covered by a display string with embedded newlines.
5731 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
5733 * dbusbind.c (Fdbus_register_signal): Add match rule to
5734 Vdbus_registered_objects_table. (Bug#9581)
5735 (Fdbus_register_method, Vdbus_registered_objects_table):
5736 Fix docstring.
5738 2011-09-24 Jim Meyering <meyering@redhat.com>
5740 do not ignore write error for any output size
5741 The previous change was incomplete.
5742 While it makes emacs --batch detect the vast majority of stdout
5743 write failures, errors were still ignored whenever the output size is
5744 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
5745 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
5746 && echo FAIL: ignored write error
5747 FAIL: ignored write error
5748 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
5749 && echo FAIL: ignored write error
5750 FAIL: ignored write error
5751 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
5753 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
5755 * emacs.c (Fkill_emacs): In noninteractive mode exit
5756 non-successfully if a write error occurred on stdout. (Bug#9574)
5758 2011-09-21 Eli Zaretskii <eliz@gnu.org>
5760 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
5761 the xassert test.
5763 * dispextern.h (struct it): Update the comment documenting what
5764 can it->OBJECT be.
5766 2011-09-20 Eli Zaretskii <eliz@gnu.org>
5768 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
5769 a display string, extend search for cursor position to end of row.
5770 (find_row_edges): If the row ends in a newline from a display
5771 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
5772 Handle the case of a display string with multiple newlines.
5773 (Fcurrent_bidi_paragraph_direction): Fix search for previous
5774 non-empty line. Fixes confusing cursor motion with arrow keys at
5775 the beginning of a line that starts with whitespace.
5777 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
5779 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
5780 (bug#9493).
5782 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
5784 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
5785 boolean (Bug#9154).
5787 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5789 * xdisp.c (display_line): Record maximum and minimum buffer
5790 positions even if no glyphs were produced (e.g., by a zero-width
5791 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
5792 buffer positions that will be removed from the glyph row because
5793 they don't fit.
5794 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
5795 column is beyond frame width: don't subtract 1 "pixel" when
5796 computing width of the stretch.
5797 (reseat_at_next_visible_line_start): Undo the change made on
5798 2011-09-17 that saved paragraph information and restored it after
5799 the call to `reseat'. (Bug#9545)
5801 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5803 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
5804 and turn window cursor on if cleared (Bug#9415).
5806 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
5808 * search.c (boyer_moore): Take unibyte characters from pattern
5809 literally. (Bug#9458)
5811 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5813 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
5815 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
5817 Fix minor problem found by static checking.
5818 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
5819 initialized, to pacify gcc -Wuninitialized.
5821 * fileio.c: Report proper errno when syscall falls.
5822 (Finsert_file_contents): Save and restore errno,
5823 so that report_file_error outputs the correct diagnostic.
5824 (Fwrite_region) [CLASH_DETECTION]: Likewise.
5826 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5828 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
5830 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5832 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
5833 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
5835 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5837 * xdisp.c (reseat_at_next_visible_line_start): Keep information
5838 about the current paragraph and restore it after the call to reseat.
5840 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
5841 (bidi_find_paragraph_start): Search back for paragraph beginning
5842 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
5843 (bidi_move_to_visually_next): Only trigger paragraph-related
5844 computations when the last character is a newline or at EOB, not
5845 just any NEUTRAL_B. (Bug#9470)
5847 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
5848 truncated lines if point is covered by a display string. (Bug#9524)
5850 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
5852 * xselect.c: Relax test for outgoing X longs (Bug#9498).
5853 (cons_to_x_long): New function.
5854 (lisp_data_to_selection_data): Use it. Correct the test for
5855 short-versus-long data; it was negated. Break out of vector
5856 loop, for efficiency, when a long datum is discovered.
5858 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
5860 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
5862 2011-09-16 Eli Zaretskii <eliz@gnu.org>
5864 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
5865 GCC PR/17406) by declaring this function with external scope.
5867 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5869 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
5870 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
5872 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
5874 * editfns.c (Fformat): Correctly handle text properties on "%%".
5876 2011-09-15 Eli Zaretskii <eliz@gnu.org>
5878 * xterm.c (x_draw_composite_glyph_string_foreground):
5879 * w32term.c (x_draw_composite_glyph_string_foreground):
5880 * term.c (encode_terminal_code):
5881 * composite.c (composition_update_it, get_composition_id):
5882 * xdisp.c (get_next_display_element)
5883 (fill_composite_glyph_string): Add comments about special meaning
5884 of TAB characters in a composition.
5886 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5888 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
5889 This occurs when processing a multibyte format.
5890 Problem reported by Wolfgang Jenker.
5892 2011-09-15 Johan Bockgård <bojohan@gnu.org>
5894 * xdisp.c (try_cursor_movement): Only check for exact match if
5895 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
5897 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5899 Remove unused external symbols.
5900 * dispextern.h (calc_pixel_width_or_height): Remove decl.
5901 * xdisp.c (calc_pixel_width_or_height): Now static.
5902 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
5903 * indent.c (check_display_width):
5904 * w32term.c: Fix comment to match code.
5905 * xterm.c, xterm.h (x_catching_errors): Remove.
5907 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5909 * xselect.c: Use signed conversions more consistently (Bug#9498).
5910 (selection_data_to_lisp_data): Assume incoming selection data are
5911 signed integers, not unsigned. This is to be consistent with
5912 outgoing selection data, which was modified to use signed integers
5913 in as part of the fix to Bug#9196 in response to Jan D.'s comment
5914 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
5915 expects long, not unsigned long.
5917 2011-09-14 Eli Zaretskii <eliz@gnu.org>
5919 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
5920 computation of loop end. Reported by Johan Bockgård
5921 <bojohan@gnu.org>.
5923 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
5925 * frame.c (Fother_visible_frames_p): Function deleted.
5927 2011-09-12 Eli Zaretskii <eliz@gnu.org>
5929 * indent.c (compute_motion): Process display vector front to back
5930 rather than the other way around. (Bug#2496)
5932 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5934 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
5936 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
5938 * minibuf.c (Fread_from_minibuffer): Doc fix.
5940 2011-09-11 Eli Zaretskii <eliz@gnu.org>
5942 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
5943 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
5945 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
5947 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
5948 value for non-existent files.
5950 2011-09-11 Eli Zaretskii <eliz@gnu.org>
5952 * fileio.c (Finsert_file_contents): If the file cannot be opened,
5953 set its "size" to -1. This will set the modtime_size field of
5954 the corresponding buffer to -1, which is what
5955 verify-visited-file-modtime expects for files that do not exist.
5956 (Bug#9139)
5958 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
5960 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
5961 here ...
5962 * lisp.h: ... from here. push_key_description is no longer
5963 defined in keyboard.c, so its declaration should not be in
5964 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
5965 logically belongs with push_key_description.
5967 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
5969 * buffer.h: Include <sys/types.h> instead of <time.h>.
5970 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
5971 Problem reported by Herbert J. Skuhra.
5973 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
5975 * xml.c (parse_region): Make the parsing work for
5976 non-comment-starting XML files again (bug#9144).
5978 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
5980 * image.c (gif_load): Fix calculation of bottom and right corner.
5981 (Bug#9468)
5983 2011-09-10 Eli Zaretskii <eliz@gnu.org>
5985 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
5986 redisplay in small windows.
5988 2011-09-09 Eli Zaretskii <eliz@gnu.org>
5990 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
5992 2011-09-08 Martin Rudalics <rudalics@gmx.at>
5994 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
5995 Operate on live windows only.
5997 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
5999 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6001 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6003 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6004 only under bidi iteration.
6006 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6008 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6010 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6012 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6013 Without this fix, the command to link temacs failed due to an
6014 undefined symbol __builtin_isnan. This is because
6015 /usr/include/iso/math_c99.h #defines isnan(x) to
6016 __builtin_isnan(x), but the bundled gcc, which identifies itself
6017 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6018 a __builtin_isnan.
6019 * floatfns.c (isnan): #undef, and then #define to a clone of
6020 what's in data.c.
6021 (Fisnan): Always define, since it's always available now.
6022 (syms_of_floatfns): Always define isnan at the Lisp level.
6024 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6026 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6028 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6030 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6031 The previous code assumed that file offsets (off_t values) fit in
6032 EMACS_INT variables, which is not true on typical 32-bit hosts.
6033 The code messed up by falsely reporting buffer overflow in cases
6034 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6035 when "big" contains more than 2**29 bytes, even though this
6036 inserts just one byte and does not overflow the buffer.
6037 (Finsert_file_contents): Store file offsets as off_t
6038 values, not as EMACS_INT values. Check for overflow when
6039 converting between EMACS_INT and off_t. When checking for
6040 buffer overflow or for overlap, take the offsets into account.
6041 Don't use EMACS_INT for small values where int suffices.
6042 When checking for overlap, fix a typo: ZV was used where
6043 ZV_BYTE was intended.
6044 (Fwrite_region): Don't assume off_t fits into 'long'.
6045 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6047 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6049 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6051 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6053 sprintf-related integer and memory overflow issues (Bug#9412).
6055 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6056 (esprintf, exprintf, evxprintf): New functions.
6057 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6058 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6059 (modify_event_symbol): Do not assume that the length of
6060 name_alist_or_stem is safe to alloca and fits in int.
6061 (Fexecute_extended_command): Likewise for function name and binding.
6062 (Frecursion_depth): Wrap around reliably on integer overflow.
6063 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6064 since some callers pass EMACS_INT values.
6065 (Fsingle_key_description): Don't crash if symbol name contains more
6066 than MAX_ALLOCA bytes.
6067 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6068 (get_minibuffer): Arg is now EMACS_INT, not int.
6069 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6070 (esprintf, exprintf, evxprintf): New decls.
6071 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6073 * dbusbind.c (signature_cat): New function.
6074 (xd_signature, Fdbus_register_signal):
6075 Do not overrun buffer; instead, report string overflow.
6077 * dispnew.c (add_window_display_history): Don't overrun buffer.
6078 Truncate instead; this is OK since it's just a log.
6080 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6081 even if the time zone offset is outlandishly large.
6082 Don't mishandle offset == INT_MIN.
6084 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6085 when creating daemon; the previous buffer-overflow check was incorrect.
6087 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6088 which has the guts of the old verror function.
6090 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6091 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6093 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6094 (font_unparse_xlfd): Don't blindly alloca long strings.
6095 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6096 fits in int, when using sprintf. Use single snprintf to count
6097 length of string rather than counting it via multiple sprintfs;
6098 that's simpler and more reliable.
6099 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6100 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6101 sprintf, in case result does not fit in int.
6103 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6104 (fontset_from_font): Print it.
6106 * frame.c (tty_frame_count): Now printmax_t, not int.
6107 (make_terminal_frame, set_term_frame_name): Print it.
6108 (x_report_frame_params): In X, window IDs are unsigned long,
6109 not signed long, so print them as unsigned.
6110 (validate_x_resource_name): Check for implausibly long names,
6111 and don't assume name length fits in 'int'.
6112 (x_get_resource_string): Don't blindly alloca invocation name;
6113 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6114 not fit in int.
6116 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6117 (xg_check_special_colors, xg_set_geometry):
6118 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6120 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6121 Use esprintf, not sprintf, in case result does not fit in int.
6123 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6124 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6125 it as a large positive number.
6126 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6127 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6129 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6130 in case result does not fit in int.
6132 * print.c (float_to_string): Detect width overflow more reliably.
6133 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6134 buffer overrun. Don't assume list length fits in 'int'. Treat
6135 print length of 0 as 0, not as infinity; to be consistent with other
6136 uses of print length in this function. Don't overflow print length
6137 index. Don't assume hash table size fits in 'long', or that
6138 vectorlike size fits in 'unsigned long'.
6140 * process.c (make_process): Use printmax_t, not int, to format
6141 process-name gensyms.
6143 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6145 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6146 to avoid potential buffer overrun.
6148 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6149 if X resource line is longer than 512 bytes.
6151 * xfns.c (x_window): Make sprintf buffer a bit bigger
6152 to avoid potential buffer overrun.
6154 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6156 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6158 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6160 Integer overflow fixes for scrolling, etc.
6161 Without these, Emacs silently mishandles large integers sometimes.
6162 For example, "C-u 4294967297 M-x recenter" was treated as if
6163 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6165 * xdisp.c (try_window_id): Check Emacs fixnum range before
6166 converting to 'int'.
6168 * window.c (window_scroll_line_based, Frecenter):
6169 Check that an Emacs fixnum is in range before assigning it to 'int'.
6170 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6171 values converted from Emacs fixnums.
6172 (Frecenter): Don't wrap around a line count if it is out of 'int'
6173 range; instead, treat it as an extreme value.
6174 (Fset_window_configuration, compare_window_configurations):
6175 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6177 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6178 that can exceed INT_MAX. Check that EMACS_INT value is in range
6179 before assigning it to the (possibly-narrower) index.
6180 (match_limit): Don't assume that a fixnum can fit in 'int'.
6182 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6183 exceed INT_MAX.
6185 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6186 (Fvertical_motion): Don't wrap around LINES values that don't fit
6187 in 'int'. Instead, treat them as extreme values. This is good
6188 enough for windows, which can't have more than INT_MAX lines anyway.
6190 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6192 * Require libxml/parser.h to avoid compilation warning.
6194 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6196 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6197 since this reportedly can destroy thread storage.
6199 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6201 * syntax.c (find_defun_start): Update all cache variables if
6202 exiting early (Bug#9401).
6204 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6206 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6208 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6209 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6210 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6212 * term.c (tty_append_glyph): New function.
6213 (produce_stretch_glyph): Static function and its prototype deleted.
6215 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6216 Add prototypes.
6218 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6220 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6221 when checking :margin (Bug#9390).
6222 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6223 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6224 so that the name doesn't mislead. All uses changed.
6226 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6228 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6229 set_tty_hooks.
6231 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6233 * xdisp.c (move_it_to): Don't bail out early when reaching
6234 position beyond to_charpos, if we are scanning backwards.
6235 (move_it_vertically_backward): When DY == 0, make sure we get to
6236 the first character in the line after the newline.
6238 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6240 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6241 (ccl_driver): Do not generate an out-of-range pointer.
6242 (Fccl_execute_on_string): Remove unnecessary check for
6243 integer overflow, noted by Stefan Monnier in
6244 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6245 Remove a FIXME that didn't need fixing.
6246 Simplify the newly-introduced buffer reallocation code.
6248 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6250 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6252 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6254 Integer and memory overflow issues (Bug#9196).
6256 * doc.c (get_doc_string): Rework so that
6257 get_doc_string_buffer_size is the actual buffer size, rather than
6258 being 1 less than the actual buffer size; this makes xpalloc more
6259 convenient.
6261 * image.c (x_allocate_bitmap_record, cache_image):
6262 * xselect.c (Fx_register_dnd_atom):
6263 Simplify previous changes by using xpalloc.
6265 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6266 since either will do and ptrdiff_t is convenient with xpalloc.
6268 * charset.c (charset_table_size)
6269 (struct charset_sort_data.priority): Now ptrdiff_t.
6270 (charset_compare): Don't overflow if priorities differ greatly.
6271 (Fsort_charsets): Don't assume list length fits in int.
6272 Check for size-calculation overflow when allocating sort data.
6273 (syms_of_charset): Allocate an initial charset table that is
6274 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6276 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6278 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6279 The actual value is always <= INT_MAX, and leaving it unsigned made
6280 overflow checking harder.
6282 * dispextern.h (struct glyph_matrix.rows_allocated)
6283 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6284 with xpalloc. The values are still always <= INT_MAX.
6286 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6288 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6289 (SAFE_NALLOCA): New macro.
6291 * region-cache.c (struct boundary.pos, find_cache_boundary)
6292 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6293 (set_cache_region, invalidate_region_cache)
6294 (revalidate_region_cache, know_region_cache, region_cache_forward)
6295 (region_cache_backward, pp_cache):
6296 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6297 so that ptrdiff_t * can be passed to xpalloc.
6298 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6299 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6300 (pp_cache): Don't assume cache_len fits in int.
6301 * region-cache.h: Adjust extern decls to match.
6303 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6304 EMACS_INT, since either will do, for xpalloc.
6306 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6307 (xnmalloc, xnrealloc, xpalloc): New functions.
6309 * bidi.c (bidi_shelve_header_size): New constant.
6310 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6311 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6313 * bidi.c (bidi_cache_shrink):
6314 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6315 (overlay_strings):
6316 Don't update size of array until after memory allocation succeeds,
6317 because xmalloc/xrealloc may not return.
6318 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6319 now that we have proper integer overflow checking.
6320 (record_overlay_string, overlay_strings): Catch overflows when
6321 calculating size of overlay_str_buf.
6323 * callproc.c (Fcall_process): Check for size overflow when
6324 calculating size of args2.
6325 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6326 Normally we prefer signed values, but sticking with ptrdiff_t would
6327 require adding more-complicated checks.
6329 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6330 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6331 Redo buffer-overflow calculations to avoid integer overflow.
6332 Add a FIXME comment where memory seems to be over-allocated.
6334 * character.c (Fstring): Check for size-calculation overflow.
6336 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6337 unnecessary integer overflow. Check for size overflow.
6338 (encode_coding_object): Don't update size until xmalloc succeeds.
6340 * composite.c (get_composition_id): Check for overflow in glyph
6341 length calculations.
6343 Integer and memory overflow fixes for display code.
6344 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
6345 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6346 (scrolling_window): Check for overflow in size calculations.
6347 (line_draw_cost, realloc_glyph_pool, add_row_entry):

6359 (get_doc_string): Check for size calculation overflow.
6360 Don't update size until allocation succeeds.
6361 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
6362 EMACS_INT, where ptrdiff_t will do.
6363 (Fsubstitute_command_keys): Check for string overflow.
6365 * editfns.c (set_time_zone_rule): Don't assume environment length
6366 fits in int.
6367 (message_length): Now ptrdiff_t, not int.
6368 (Fmessage_box): Don't update size until allocation succeeds.
6369 Don't assume message length fits in int.
6370 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6372 * emacs.c (main): Do not reallocate argv, since there is a null at
6373 the end that can be overwritten, and this way there's no need to
6374 worry about size-calculation overflow.
6375 (sort_args): Check for size-calculation overflow.
6377 * eval.c (init_eval_once, grow_specpdl): Don't update size until
6378 alloc succeeds.
6379 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
6381 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
6382 (x_set_scroll_bar_width, x_figure_window_size):
6383 Check for integer overflow.
6384 (x_set_alpha): Do not assume XINT fits in int.
6386 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6387 This is for the members text_lines, text_cols, total_lines, total_cols,
6388 where the system imposes an 'int' limit.
6390 * fringe.c (Fdefine_fringe_bitmap):
6391 Don't update size until alloc works.
6393 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
6394 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
6396 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
6397 Check for size-calculation overflow.
6398 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6399 do, as we prefer signed integers.
6400 (id_to_widget.max_size, id_to_widget.used)
6401 (xg_store_widget_in_map, xg_remove_widget_from_map)
6402 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
6403 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
6404 Use and return ptrdiff_t, not int.
6405 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
6406 * gtkutil.h: Change prototypes to match the above.
6408 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
6409 are duplicate now that they've been promoted to lisp.h.
6410 (x_allocate_bitmap_record, x_alloc_image_color)
6411 (make_image_cache, cache_image, xpm_load):
6412 Don't update size until alloc is done.

6422 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
6423 Use ptrdiff_t, not int, to count maps.
6424 (read_char_minibuf_menu_prompt): Check for overflow in size
6425 calculations. Don't update size until allocation succeeds.
6426 Redo calculations to avoid overflow.
6427 * keyboard.h: Change prototypes to match the above.

6434 * lread.c (read1, init_obarray): Don't update size until alloc done.
6436 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
6437 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.

6453 (Fset_match_data): Don't assume list lengths fit in 'int'.
6455 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
6456 for command line length. Do not attempt to address one before the
6457 beginning of an array, as that's not portable.
6459 * term.c (max_frame_lines): Remove; unused.
6460 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
6461 not int.

6463 calculation overflow.
6464 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
6465 table lengths and related sizes. Don't update size until alloc
6466 done. Redo calculations to avoid overflow.
6467 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
6469 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
6470 subtracting pointers.

6472 until alloc done.
6474 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

6485 Use ptrdiff_t, not int, for sizes.
6486 (Finternal_make_lisp_face, cache_face):
6487 Check for size calculation overflow.
6488 (cache_face): Treat size calculation overflows as if they were
6489 memory exhaustion (the usual treatment), rather than aborting.
6491 * xfns.c (x_encode_text, x_set_name_internal)
6492 (Fx_change_window_property): Use ptrdiff_t, not int, to count
6493 sizes, since they can exceed INT_MAX in size. Check for size

6497 (xg_select): Check for size calculation overflow.
6498 Don't update size until alloc done.
6500 * xrdb.c (get_environ_db): Don't assume path length fits in int,
6501 as sprintf is limited to int lengths.
6503 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
6504 (X_LONG_MIN): New macros.
6505 Use them to make the following changes clearer.
6506 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6507 This change doesn't affect the value now, but it may help remind
6508 future maintainers not to raise the value too much later.
6509 (SELECTION_QUANTUM): Remove, replacing with ...
6510 (selection_quantum): ... new function, which avoids overflow.
6511 All uses changed.
6512 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
6513 assumption that selection length fits in 'int'.
6514 (x_reply_selection_request, x_handle_selection_request)
6515 (x_get_window_property, receive_incremental_selection)
6516 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
6517 (lisp_data_to_selection_data, clean_local_selection_data):
6518 Use ptrdiff_t, not int, to record length of selection.
6519 (x_reply_selection_request, x_get_window_property)

6521 Redo calculations to avoid overflow.
6522 (x_reply_selection_request): When sending hint, ceiling it at
6523 X_LONG_MAX rather than relying on wraparound overflow to send
6524 something.
6525 (x_get_window_property, receive_incremental_selection)
6526 (lisp_data_to_selection_data, x_property_data_to_lisp):
6527 Check for size-calculation overflow.
6528 (x_get_window_property, receive_incremental_selection)
6529 (lisp_data_to_selection_data, Fx_register_dnd_atom):
6530 Don't store size until memory allocation succeeds.
6531 (x_get_window_property): Plug memory leak on memory exhaustion.
6532 Don't double-block input; malloc is safe here. Don't assume 2**34
6533 - 4 fits in unsigned long. Add an xassert to check
6534 XGetWindowProperty overflow. Be more careful about overflow
6535 calculations, and distinguish size from memory overflow better.
6536 (receive_incremental_selection): When tracing, don't assume
6537 unsigned int is less than INT_MAX.
6538 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
6539 harmful) conversions of unsigned short to int.
6540 (lisp_data_to_selection_data): Don't assume that integers
6541 in the range -65535 through -1 fit in an X unsigned short.
6542 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
6543 result parameters unless successful. Rely on cons_to_unsigned
6544 to report problems with elements; the old code wasn't right anyway.
6545 (x_check_property_data): Check for int overflow; we cannot use
6546 a wider type due to X limits.
6547 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
6549 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

6552 (x_term_init): Check for size calculation overflow.
6553 (x_color_cells): Don't store size until memory allocation succeeds.

6555 Don't assume alloca size is less than MAX_ALLOCA.
6556 (x_term_init): Don't assume length fits in int (sprintf is limited
6557 to int size).
6559 Use ptrdiff_t for composition IDs.
6560 * character.c (lisp_string_width):
6561 * composite.c (composition_table_size, n_compositions)

6578 * image.c (xpm_get_color_table_h):
6579 * lisp.h (hash_lookup, hash_put):
6580 * minibuf.c (Ftest_completion):
6581 Use ptrdiff_t for hash table indexes, not int (which is too
6582 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
6583 32-bit --with-wide-int hosts).
6585 * charset.c (Fdefine_charset_internal): Check for integer overflow.
6586 Add a FIXME comment about memory leaks.
6587 (syms_of_charset): Don't assume xmalloc returns.
6589 Don't assume that stated character widths fit in int.
6590 * character.c (Fchar_width, c_string_width, lisp_string_width):
6591 * character.h (CHAR_WIDTH):
6592 * indent.c (MULTIBYTE_BYTES_WIDTH):
6593 Use sanitize_char_width to avoid undefined and/or bad behavior
6594 with outlandish widths.
6595 * character.h (sanitize_tab_width): Rename from sanitize_width,
6596 now that we have two such functions. All uses changed.
6597 (sanitize_char_width): New inline function.
6599 Don't assume that tab-width fits in int.
6600 * character.h (sanitize_width): New inline function.
6601 (SANE_TAB_WIDTH): New macro.

6603 * indent.c (sane_tab_width): Remove. All uses replaced by
6604 SANE_TAB_WIDTH (current_buffer).
6605 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
6607 * fileio.c: Integer overflow issues with file modes.
6608 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
6610 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

6614 * xterm.c: Don't go over XClientMessageEvent limit.
6615 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
6616 (x_send_scroll_bar_event): Likewise. Check that the size does not
6617 exceed limits imposed by XClientMessageEvent, as well as the usual
6618 ptrdiff_t and size_t limits.
6620 * keyboard.c: Overflow, signedness and related fixes.
6621 (make_lispy_movement): Use same integer type in forward decl
6622 that is used in the definition.
6623 (read_key_sequence, keyremap_step):
6624 Change bufsize argument back to int, undoing my 2011-03-30 change.
6625 We prefer signed types, and int is wide enough here.
6626 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6627 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
6628 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
6629 length, not size_t. Use ptrdiff_t for index, not int.
6630 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
6631 possibility of integer overflow.
6633 Overflow, signedness and related fixes for images.
6635 * dispextern.h (struct it.stack[0].u.image.image_id)

6641 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
6642 * nsmenu.m (update_frame_tool_bar):
6643 * xdisp.c (calc_pixel_width_or_height):
6644 * xfns.c (image_cache_refcount):
6645 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
6646 on typical 64-bit hosts.
6648 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6649 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

6654 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
6655 (lookup_image): Remove unnecessary tests.
6656 (xbm_image_p): Locals are now of int, not EMACS_INT,
6657 since parse_image_check makes sure they fit into int.
6658 (png_load, gif_load, svg_load_image):
6659 Prefer int to unsigned where either will do.
6660 (tiff_handler): New function, combining the cores of the
6661 old tiff_error_handler and tiff_warning_handler.
6662 This function is rewritten to use vsnprintf and thereby avoid
6663 stack buffer overflows. It uses only the features of vsnprintf
6664 that are common to both POSIX and native Microsoft.
6665 (tiff_error_handler, tiff_warning_handler): Use it.
6666 (tiff_load, gif_load, imagemagick_load_image):
6667 Don't assume :index value fits in 'int'.
6668 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
6669 (imagemagick_load_image): Check that crop parameters fit into
6670 the integer types that MagickCropImage accepts. Don't assume
6671 Vimagemagick_render_type has a nonnegative value. Don't assume
6672 size_t fits in 'long'.
6673 (gs_load): Use printmax_t to print the widest integers possible.
6674 Check for integer overflow when computing image height and width.
6676 2011-08-26 Eli Zaretskii <eliz@gnu.org>
6678 * xdisp.c (redisplay_window): Don't force window start if point
6679 will be invisible in the resulting window. (Bug#9324)
6681 2011-08-25 Eli Zaretskii <eliz@gnu.org>
6683 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
6684 the display spec is of the form `(space ...)'.
6685 (handle_display_spec): Return the value returned by
6686 handle_single_display_spec, not just 1 or zero.
6687 (handle_single_display_spec): If the display spec is of the form
6688 `(space ...)', and specifies display in the text area, return 2
6689 rather than 1.
6690 (try_cursor_movement): Check for the need to scroll more
6691 accurately, and prefer exact match for point under bidi.
6692 Don't advance `row' beyond the last row of the window.
6694 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
6695 into disp_prop; all users changed.
6697 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
6698 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
6699 for the text covered by the display property.

6709 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
6710 buffers, return left-to-right.
6711 (set_cursor_from_row): Consider candidate row a win if its glyph
6712 represents a newline and point is on that newline. Fixes cursor
6713 positioning on the newline at EOL of R2L text within L2R
6714 paragraph, and vice versa.
6715 (try_cursor_movement): Check continued rows, in addition to
6716 continuation rows. Fixes unwarranted scroll when point enters a
6717 continued line of R2L text within an L2R paragraph, or vice versa.
6718 (cursor_row_p): Consider the case of point being equal to
6719 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
6720 from the end of a short line to the beginning of a continued line
6721 of R2L text within L2R paragraph.
6722 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

6741 extra slot even if the purpose is char-code-property-table.
6743 2011-08-23 Eli Zaretskii <eliz@gnu.org>
6745 * xdisp.c (redisplay_window): When computing centering_position,
6746 account for the height of the header line. (Bug#8874)
6748 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
6749 instead of CHAR_TO_BYTE. Fixes a crash when a completion
6750 candidate is selected by the mouse, and that candidate has a
6751 composed character under the mouse.
6753 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
6754 coordinates reported by pos-visible-in-window-p for a composed
6755 character in column zero.
6757 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

6761 2011-08-22 Eli Zaretskii <eliz@gnu.org>
6763 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
6764 consider it a hit if to_charpos is anywhere in the range of the
6765 composed buffer positions.
6767 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
6769 * image.c (gif_load): Don't assume that each subimage has the same
6770 dimensions as the base image. Handle disposal method that is
6771 "undefined" by the gif spec (Bug#9335).
6773 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
6775 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
6776 (Fcondition_case): Document `debug' symbol in error handler.
6778 2011-08-19 Eli Zaretskii <eliz@gnu.org>
6780 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
6781 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
6782 from an Org mode buffer to a Speedbar frame.
6784 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
6785 a composition, take its buffer position from IT->cmp_it.charpos.
6786 Fixes cursor positioning at the beginning of a line that begins
6787 with a composed character.
6789 2011-08-18 Eli Zaretskii <eliz@gnu.org>
6791 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
6792 character bidirectional type, use STRONG_L instead. Fixes crashes
6793 in a buffer produced by `describe-categories'.
6795 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
6796 members before the level stack, so they would be saved and
6797 restored when copying iterator state. Fixes incorrect reordering
6798 around TABs covered by display properties.
6800 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
6802 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

6807 (internal_condition_case_2, internal_condition_case_n):
6808 Remove unnecessary aborts (Bug#9081).
6810 2011-08-17 Eli Zaretskii <eliz@gnu.org>
6812 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
6813 has no `load' handler, try opening the file locally. (Bug#9311)
6815 2011-08-16 Ken Brown <kbrown@cornell.edu>
6817 * gmalloc.c: Expand comment.
6819 2011-08-16 Eli Zaretskii <eliz@gnu.org>
6821 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
6822 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

6872 * xdisp.c (move_it_in_display_line_to): Don't invoke
6873 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
6874 ppos_it. Fixes vertical cursor motion when line beginning is
6875 covered by an image. (Bug#9296)
6877 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
6879 * nsterm.h (ns_run_ascript): Declare.

6886 the event loop. Get status from as_status (Bug#7276).
6888 * nsterm.m (sendEvent): If event is NSApplicationDefined and
6889 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
6890 the event loop (Bug#7276).
6892 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
6894 * gnutls.c (QCgnutls_bootprop_priority)

6916 (Fnetwork_interface_list): Allocate in increments of bytes instead
6917 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting

6922 Get hardware address with getifaddrs if available.
6924 2011-08-12 Eli Zaretskii <eliz@gnu.org>
6926 * xdisp.c (iterate_out_of_display_property): xassert that
6927 IT->position is set to within IT->object's boundaries. Break from
6928 the loop as soon as EOB is reached; avoids infloops in redisplay
6929 when IT->position is set up wrongly due to some bug.
6930 Set IT->current to match the bidi iterator unconditionally.
6931 (push_display_prop): Allow GET_FROM_STRING as IT->method on
6932 entry. Force push_it to save on the stack the current
6933 buffer/string position, to be restored by pop_it. Fix flags in
6934 the iterator structure wrt the object coming from a display
6935 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
6936 properties. (Bug#9284)
6938 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
6940 * fontset.c (fontset_get_font_group): Add proper type checks.

6955 properties and overlays.
6957 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
6959 * editfns.c (Fset_time_zone_rule): Document relationship with the

6968 restore_point_unwind (Bug#5984).
6970 2011-08-07 Juri Linkov <juri@jurta.org>
6972 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
6973 to show the arg `TIME' instead of `TIMEVAL'.
6975 2011-08-06 Eli Zaretskii <eliz@gnu.org>
6977 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
6978 display property strides EOL and includes a newline, as in
6979 longlines-mode. (Bug#9254)
6980 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
6981 word-wrap under bidirectional display. (Bug#9224)
6983 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
6984 is non-zero, even if the data buffer is NULL. Fixes a crash in
6985 vertical-motion with longlines-mode. (Bug#9254)
6987 2011-08-05 Eli Zaretskii <eliz@gnu.org>
6989 * bidi.c <bidi_cache_total_alloc>: Now static.
6990 (bidi_initialize): Initialize bidi_cache_total_alloc.
6992 * xdisp.c (display_line): Release buffer allocated for shelved bidi
6993 cache. (Bug#9221)
6995 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
6996 amount allocated this far in `bidi_cache_total_alloc'.
6997 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
6998 non-zero, only free the data buffer without restoring the cache
6999 contents. All callers changed.
7001 * dispextern.h (bidi_unshelve_cache): Update prototype.
7003 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7004 (move_it_in_display_line, move_it_to)
7005 (move_it_vertically_backward, move_it_by_lines): Replace the call
7006 to xfree to an equivalent call to bidi_unshelve_cache.
7007 (move_it_in_display_line_to): Fix logic of returning
7008 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7010 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7012 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7013 came from a string character with a `cursor' property. (Bug#9229)

7061 non-zero.
7063 * bidi.c (bidi_fetch_char): Accept an additional argument
7064 DISP_PROP_P, and pass it to compute_display_string_pos.
7065 Only handle text covered by a display string if DISP_PROP_P is returned
7066 non-zero. All callers of bidi_fetch_char changed.

7153 Without this fix, if a signal arrives just after memory fills up,
7154 'malloc' might be invoked reentrantly.
7156 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7157 In other words, assume that every image size is allowed, on non-X
7158 hosts. This assumption is probably wrong, but it lets Emacs compile.
7160 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7162 * regex.c (re_iswctype): Convert return values to boolean.
7164 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7166 * xdisp.c (compute_display_string_pos): Don't use cached display
7167 string position if the buffer had its restriction changed.
7168 (Bug#9184)
7170 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7172 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7174 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7176 Integer signedness and overflow and related fixes. (Bug#9079)
7178 * bidi.c: Integer size and overflow fixes.
7179 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7180 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7181 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7182 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7183 (bidi_find_other_level_edge):
7184 Use ptrdiff_t instead of EMACS_INT where either will do.
7185 This works better on 32-bit hosts configured --with-wide-int.
7186 (bidi_cache_ensure_space): Check for size-calculation overflow.
7187 Use % rather than repeated addition, for better worst-case speed.
7188 Don't set bidi_cache_size until after xrealloc returns, because it
7189 might not return.
7190 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7191 (bidi_cache_ensure_space): Also check that the bidi cache size
7192 does not exceed that of the largest Lisp string or buffer. See Eli
7193 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7195 * alloc.c (__malloc_size_t): Remove.
7196 All uses replaced by size_t. See Andreas Schwab's note
7197 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7199 * image.c: Improve checking for integer overflow.
7200 (check_image_size): Assume that f is nonnull, since
7201 it is always nonnull in practice. This is one less thing to
7202 worry about when checking for integer overflow later.
7203 (x_check_image_size): New function, which checks for integer
7204 overflow issues inside X.
7205 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7206 This removes the need for a memory_full check.
7207 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7208 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7209 (xbm_read_bitmap_data): Change locals back to 'int', since
7210 their values must fit in 'int'.
7211 (xpm_load_image, png_load, tiff_load):
7212 Invoke x_create_x_image_and_pixmap earlier,
7213 to avoid much needless work if the image is too large.
7214 (tiff_load): Treat overly large images as if
7215 x_create_x_image_and_pixmap failed, not as malloc failures.
7216 (gs_load): Use x_check_image_size.
7218 * gtkutil.c: Omit integer casts.
7219 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7220 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7222 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7224 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7225 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7226 would wrongly return t on a 64-bit host.
7228 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7229 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7230 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7231 and therefore cause GCC to emit a bogus diagnostic in some cases.
7233 * image.c: Integer signedness and overflow and related fixes.
7234 This is not an exhaustive set of fixes, but it's time to
7235 record what I've got.
7236 (lookup_pixel_color, check_image_size): Remove redundant decls.
7237 (check_image_size): Don't assume that arbitrary EMACS_INT values
7238 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7239 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7240 (tiff_load, imagemagick_load_image):
7241 Check for overflow in size calculations.
7242 (x_create_x_image_and_pixmap): Remove unnecessary test for
7243 xmalloc returning NULL; that can't happen.
7244 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7245 (xpm_color_bucket): Use better integer hashing function.
7246 (xpm_cache_color): Don't possibly over-allocate memory.
7247 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7248 (gif_memory_source):
7249 Use ptrdiff_t, not int or size_t, to record sizes.
7250 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7251 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7252 either works, as we prefer signed integers.
7253 (tiff_read_from_memory, tiff_write_from_memory):
7254 Return tsize_t, not size_t, since that's what the TIFF API wants.
7255 (tiff_read_from_memory): Don't fail simply because the read would
7256 go past EOF; instead, return a short read.
7257 (tiff_load): Omit no-longer-needed casts.
7258 (Fimagemagick_types): Don't assume size fits into 'int'.
7260 Improve hashing quality when configured --with-wide-int.
7261 * fns.c (hash_string): New function, taken from sxhash_string.
7262 Do not discard information about ASCII character case; this
7263 discarding is no longer needed.
7264 (sxhash-string): Use it. Change sig to match it. Caller changed.
7265 * lisp.h: Declare it.
7266 * lread.c (hash_string): Remove, since we now use fns.c's version.
7267 The fns.c version returns a wider integer if --with-wide-int is
7268 specified, so this should help the quality of the hashing a bit.
7270 * emacs.c: Integer overflow minor fix.
7271 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7272 Define only if GNU_LINUX.
7273 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7275 * dispnew.c: Integer signedness and overflow fixes.
7276 Remove unnecessary forward decls, that were a maintenance hassle.
7277 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7278 All uses changed.
7279 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7280 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7281 (prepare_desired_row, line_draw_cost):
7282 Use int, not unsigned, where either works.
7283 (save_current_matrix, restore_current_matrix):
7284 Use ptrdiff_t, not size_t, where either works.
7285 (init_display): Check for overflow more accurately, and without
7286 relying on undefined behavior.
7288 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7289 Remove, replacing with the new symbols in lisp.h. All uses changed.
7290 * fileio.c (make_temp_name):
7291 * filelock.c (lock_file_1, lock_file):
7292 * xdisp.c (message_dolog):
7293 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7294 Use pMd etc. instead.
7295 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7296 replacing the pWIDE etc. symbols removed from editfns.c.
7298 * keyboard.h (num_input_events): Now uintmax_t.
7299 This is (very slightly) less likely to mess up due to wraparound.
7300 All uses changed.
7302 * buffer.c: Integer signedness fixes.
7303 (alloc_buffer_text, enlarge_buffer_text):
7304 Use ptrdiff_t rather than size_t when either will do, as we prefer
7305 signed integers.
7307 * alloc.c: Integer signedness and overflow fixes.
7308 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7309 (__malloc_size_t): Default to size_t, not to int.
7310 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7311 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7312 Prefer ptrdiff_t to size_t when either would do, as we prefer
7313 signed integers.
7314 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7315 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7316 Now const. Initialize with values that are in range even if char
7317 is signed.
7318 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7319 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7320 These functions do the right thing with sizes > 2**32.
7321 (check_depth): Now ptrdiff_t, not int.
7322 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7323 Adjust to new way of storing sizes. Check for size overflow bugs
7324 in rest of code.
7325 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7326 slightly wrong anyway, as it missed one instance of
7327 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7328 (refill_memory_reserve): Omit needless cast to size_t.
7329 (mark_object_loop_halt): Mark as externally visible.
7331 * xselect.c: Integer signedness and overflow fixes.
7332 (Fx_register_dnd_atom, x_handle_dnd_message):
7333 Use ptrdiff_t, not size_t, since we prefer signed.
7334 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7335 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7336 x_dnd_atoms_size and x_dnd_atoms_length.
7338 * doprnt.c: Prefer signed to unsigned when either works.
7339 * eval.c (verror):
7340 * doprnt.c (doprnt):
7341 * lisp.h (doprnt):
7342 * xdisp.c (vmessage):
7343 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7344 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7345 prefer signed arithmetic to avoid comparison confusion.
7346 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7347 but is a bit tricky.
7349 Assume freestanding C89 headers, string.h, stdlib.h.
7350 * data.c, doprnt.c, floatfns.c, print.c:
7351 Include float.h unconditionally.
7352 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7353 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7354 * regex.c: Likewise for stddef.h, string.h.
7355 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7356 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7357 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7358 (STDC_HEADERS): Remove obsolete defines.
7359 * sysdep.c: Include limits.h unconditionally.
7361 Assume support for memcmp, memcpy, memmove, memset.
7362 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7363 * regex.c (memcmp, memcpy):
7364 Remove; we assume C89 now.
7366 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7367 (__malloc_safe_bcopy): Remove; no longer needed.
7369 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7370 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7371 well either way, and we prefer signed to unsigned.
7373 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7375 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7376 closes the connection while we're reading (bug#9182).
7378 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7380 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7381 are specified (Bug#9168).
7383 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7385 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7386 Found by GCC static checking and --with-wide-int on a 32-bit host.
7388 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7390 * xdisp.c (compute_display_string_pos): Fix logic of caching
7391 previous display string position. Initialize cached_prev_pos to
7392 -1. Fixes slow-down at the beginning of a buffer.
7394 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7396 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7397 for attrs[LFACE_FONTSET_INDEX].
7399 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7401 * xml.c (parse_region): Remove unused local
7402 that was recently introduced.
7404 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7406 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7407 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7409 * xdisp.c (move_it_in_display_line_to): Record the best matching
7410 position for TO_CHARPOS while scanning the line, and restore it on
7411 exit if none of the characters scanned was an exact match.
7412 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7413 when exact match is impossible due to invisible text, and the
7414 lines are truncated.
7416 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7418 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7419 for OSX >= 10.7.
7421 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7423 Fix a significant slow-down of cursor motion with C-n, C-p,
7424 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7425 auto-repeat under bidi redisplay in fontified buffers.
7426 * xdisp.c (compute_stop_pos_backwards): New function.
7427 (next_element_from_buffer): Call compute_stop_pos_backwards to
7428 find a suitable prev_stop when we find ourselves before
7429 base_level_stop.
7430 (reseat): Don't look for prev_stop, as that could mean a very long
7431 run.
7432 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7433 <cached_disp_overlay_modiff>: Cache for last found display string
7434 position.
7435 (compute_display_string_pos): Return the cached position if asked
7436 about the same buffer in the same area of character positions, and
7437 the buffer wasn't changed since the time the display string
7438 position was cached.
7440 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7442 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7443 is an integer, which is important for empty lines. (Bug#9149)
7445 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7447 * frame.c (Fmodify_frame_parameters): In tty case, update the
7448 default face if necessary (Bug#4238).
7450 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7452 * editfns.c (Fstring_to_char): No need to explain what a character
7453 is in the docstring (Bug#6576).
7455 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7457 * xml.c (parse_region): Make sure we always return a tree.
7459 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7461 * xml.c (parse_region): If a document contains only comments,
7462 return that, too.
7464 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7466 * xml.c (make_dom): Return comments, too.
7468 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7470 Port to OpenBSD.
7471 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7472 and the surrounding thread.
7473 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7474 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7475 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7476 timer goes off.
7477 * s/openbsd.h (BROKEN_SIGIO): Define.
7478 * unexelf.c (unexec) [__OpenBSD__]:
7479 Don't update the .mdebug section of the Alpha COFF symbol table.
7481 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7483 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7484 (bug#8460).
7486 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7488 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7489 This fixes some race conditions on the permissions of any newly
7490 created file.
7492 * alloc.c (valid_pointer_p): Use pipe, not open.
7493 This fixes some permissions issues when debugging.
7495 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7496 If fchown fails to set both uid and gid, try to set just gid,
7497 as that is sometimes allowed. Adjust the file's mode to eliminate
7498 setuid or setgid bits that are inappropriate if fchown fails.
7500 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7502 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7503 to compare Lisp_Objects.
7504 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7505 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7506 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7508 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7510 * lread.c (read_integer): Unread even EOF character.
7511 (read1): Likewise. Properly record start position of symbol.
7513 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7514 symbol character follows.
7516 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7518 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7519 This works around a problem with the previous change to Fcopy_file.
7520 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7521 and without this change, GCC might complain about discarding
7522 fchown's return value.
7524 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7526 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7528 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7530 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7532 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7534 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7535 it's used from the C level.
7537 * process.c: Use the same condition for POLL_FOR_INPUT in both
7538 keyboard.c and process.c (bug#1858).
7540 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7542 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7543 (Fgnutls_boot): Use it.
7545 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7547 * doc.c (Fsubstitute_command_keys): Revert last change.
7549 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7551 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7552 quotes the next character, and doesn't affect other longer
7553 sequences (bug#8935).
7555 * lread.c (syms_of_lread): Clarify that is isn't only
7556 `eval-buffer' and `eval-defun' that's affected by
7557 `lexical-binding' (bug#8460).
7559 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7561 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7562 bidi redisplay when a line includes both an image and is truncated.
7564 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7566 Fix minor problems found by static checking.
7567 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7568 (elsz): Now a signed constant, not a size_t var. We prefer signed
7569 types to unsigned, to avoid integer comparison confusion. Without
7570 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7571 "cannot optimize loop, the loop counter may overflow", a symptom
7572 of the confusion.
7573 * indent.c (Fvertical_motion): Mark locals as initialized.
7574 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7576 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7578 * search.c (Fre_search_backward): Mention `case-fold-search' in
7579 all the re_search_* functions (bug#8138).
7581 * keyboard.c (Fopen_dribble_file): Document when the file is
7582 closed (bug#8056).
7584 2011-07-14 Eli Zaretskii <eliz@gnu.org>
7586 * bidi.c (bidi_dump_cached_states): Fix format of displaying
7587 bidi_cache_idx.
7589 Support bidi reordering of display and overlay strings.
7590 * xdisp.c (compute_display_string_pos)
7591 (compute_display_string_end): Accept additional argument STRING.
7592 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
7593 (reseat_to_string): Initialize bidi_it->string.s and
7594 bidi_it->string.schars.
7595 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
7596 NULL (avoids a crash in bidi_paragraph_init).
7597 Initialize itb.string.lstring.
7598 (init_iterator): Call bidi_init_it only of a valid
7599 buffer position was specified. Initialize paragraph_embedding to
7600 L2R.
7601 (reseat_to_string): Initialize the bidi iterator.
7602 (display_string): If we need to ignore text properties of
7603 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7604 original value of -1 will not work with bidi.)
7605 (compute_display_string_pos): First arg is now struct
7606 `text_pos *'; all callers changed. Support display properties on

8098 (clone_per_buffer_values): Don't assume that

8100 This isn't true in general, and it's particularly not true
8101 if Emacs is configured with --with-wide-int.
8102 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

8137 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
8139 Random fixes. E.g., (random) never returned negative values.
8140 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8141 subseconds part to the entropy, as that's a bit more random.
8142 Prefer signed to unsigned, since the signedness doesn't matter and
8143 in general we prefer signed. When given a limit, use a
8144 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8145 latter isn't right if USE_2_TAGS_FOR_INTS.
8146 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8147 not 0..VALMASK. Don't discard "excess" bits that random () returns.
8149 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8151 * textprop.c (text_property_stickiness):

8160 This is more efficient than Ffile_directory_p and avoids a minor race.
8162 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8164 * buffer.c (Foverlay_put): Say what the return value is
8165 (bug#7835).
8167 * fileio.c (barf_or_query_if_file_exists): Check first if the file
8168 is a directory before asking whether to use the file name
8169 (bug#7564).
8170 (barf_or_query_if_file_exists): Make the "File is a directory"
8171 error be more correct.
8173 * fns.c (Frequire): Remove the mention of the .gz files, since
8174 that's installation-specific, but keep the mention of
8175 `get-load-suffixes'.
8177 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8179 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

8187 Qgnutls_bootprop_verify_error (which is no longer used).
8189 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
8190 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
8191 Also (re)move comments that are misplaced or no longer relevant.
8193 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8195 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

8254 (syms_of_keymap): Defsubr make-composed-keymap.
8255 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

8290 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
8292 * eval.c (struct backtrace): Simplify and port the data structure.
8293 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8294 signed bit field, as this assumption is not portable and it makes
8295 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8296 "char debug_on_exit : 1" as this is not portable either; instead,
8297 use the portable "unsigned int debug_on_exit : 1". Remove unused
8298 member evalargs. Remove obsolete comments about cc bombing out.
8300 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

8492 (substitute_object_recurse, read_vector, read_list, map_obarray):
8493 Use ptrdiff_t, not int, for sizes.
8494 (read1): Use EMACS_INT, not int, for sizes.
8495 Check for size overflow.
8497 * image.c (cache_image): Check for size arithmetic overflow.
8499 * lread.c: Integer overflow issues.
8500 (saved_doc_string_size, saved_doc_string_length)
8501 (prev_saved_doc_string_size, prev_saved_doc_string_length):
8502 Now ptrdiff_t, not int.
8503 (read1): Don't assume doc string length fits in int. Check for
8504 out-of-range doc string lengths.
8505 (read_list): Don't assume file position fits in int.
8506 (read_escape): Check for hex character overflow.
8508 2011-06-22 Leo Liu <sdl.web@gmail.com>
8510 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
8511 Move to minibuffer.el.
8513 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8515 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
8516 The following patches are for when GLYPH_DEBUG && !XASSERT.
8517 * dispextern.h (trace_redisplay_p, dump_glyph_string):
8518 * dispnew.c (flush_stdout):
8519 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
8520 Mark as externally visible.
8521 * dispnew.c (check_window_matrix_pointers): Now static.
8522 * dispnew.c (window_to_frame_vpos):
8523 * xfns.c (unwind_create_frame):
8524 * xterm.c (x_check_font): Remove unused local.
8525 * scroll.c (CHECK_BOUNDS):
8526 * xfaces.c (cache_fache): Rename local to avoid shadowing.
8527 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8528 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8529 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8530 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8531 Now static.
8532 (debug_method_add): Use va_list and vsprintf rather than relying
8533 on undefined behavior with wrong number of arguments.
8534 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8535 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8536 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8537 since we're not interested in debugging glyphs with old libraries.
8538 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8539 GCC 4.6.0's static checking.
8541 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8543 Integer overflow and signedness fixes (Bug#8873).

8551 (x_create_bitmap_from_data, x_create_bitmap_from_file)
8552 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
8553 (x_create_bitmap_from_xpm_data):
8554 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
8555 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
8556 (.bitmaps_last):
8557 * xfaces.c (load_pixmap):
8558 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
8559 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
8560 (.bitmaps_last, struct x_output.icon_bitmap):
8561 Use ptrdiff_t, not int, for bitmap indexes.
8562 (x_allocate_bitmap_record): Check for size overflow.
8563 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
8565 Use ptrdiff_t, not int, for overlay counts.
8566 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
8567 * editfns.c (overlays_around, get_pos_property):
8568 * textprop.c (get_char_property_and_overlay):
8569 * xdisp.c (next_overlay_change, note_mouse_highlight):
8570 * xfaces.c (face_at_buffer_position):
8571 * buffer.c (OVERLAY_COUNT_MAX): New macro.
8572 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
8573 (Fnext_overlay_change, Fprevious_overlay_change)
8574 (mouse_face_overlay_overlaps, Foverlays_in):
8575 Use ptrdiff_t, not int, for sizes.
8576 (overlays_at, overlays_in): Check for size-calculation overflow.
8578 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8580 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8581 (x_session_initialize): Do not assume string length fits in int.
8583 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8584 This is unlikely, but can occur if DPI is outlandish.
8586 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8587 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8589 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
8590 * xrdb.c (magic_file_p, search_magic_path):
8591 Omit last arg SUFFIX; it was always 0. All callers changed.
8592 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
8594 * xfont.c (xfont_match): Avoid need for strlen.
8596 * xfns.c: Don't assume strlen fits in int.
8597 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
8599 * xdisp.c (message_log_check_duplicate): Return intmax_t,
8600 not unsigned long, as we prefer signed integers. All callers changed.
8601 Detect integer overflow in repeat count.
8602 (message_dolog): Don't assume print length fits in 39 bytes.
8603 (display_mode_element): Don't assume strlen fits in int.
8605 * termcap.c: Don't assume sizes fit in int and never overflow.
8606 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
8607 (gobble_line): Check for size-calculation overflow.
8609 * minibuf.c (Fread_buffer):
8610 * lread.c (intern, intern_c_string):
8611 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
8612 Don't assume string length fits in int.
8614 * keyboard.c (parse_tool_bar_item):
8615 * gtkutil.c (style_changed_cb): Avoid need for strlen.
8617 * font.c: Don't assume string length fits in int.
8618 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
8619 Use ptrdiff_t, not int.
8620 (font_intern_prop): Don't assume string length fits in int.
8621 Don't assume integer property fits in fixnum.
8622 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
8624 * filelock.c: Fix some buffer overrun and integer overflow issues.
8625 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
8626 Reformulate so as not to need the command string.
8627 Invoke gzip -cd rather than gunzip, as it's more portable.
8628 (lock_info_type, lock_file_1, lock_file):
8629 Don't assume pid_t and time_t fit in unsigned long.
8630 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8631 (current_lock_owner): Prefer signed type for sizes.
8632 Use memcpy, not strncpy, where memcpy is what is really wanted.
8633 Don't assume (via atoi) that time_t and pid_t fit in int.
8634 Check for time_t and/or pid_t out of range, e.g., via a network share.
8635 Don't alloca where an auto var works fine.
8637 * fileio.c: Fix some integer overflow issues.
8638 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8639 Don't assume string length fits in int.
8640 (directory_file_name): Don't assume string length fits in long.
8641 (make_temp_name): Don't assume pid fits in int, or that its print
8642 length is less than 20.
8644 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8646 * coding.c (make_subsidiaries): Don't assume string length fits in int.
8648 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
8650 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
8651 We prefer signed integers, even for size calculations.
8653 * emacs.c: Don't assume string length fits in 'int'.
8654 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
8655 (main): Don't invoke strlen when not needed.
8657 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
8658 (XD_DEBUG_MESSAGE): Don't waste a byte.
8660 * callproc.c (getenv_internal_1, getenv_internal)
8661 (Fgetenv_internal):
8662 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8664 * lread.c (invalid_syntax): Omit length argument.
8665 All uses changed. This doesn't fix a bug, but it simplifies the
8666 code away from its former Hollerith-constant appearance, and it's
8667 one less 'int' to worry about when looking at integer-overflow issues.
8668 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8670 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8671 This didn't break anything, but it didn't help either.
8672 It's confusing to put a bogus integer in a place where the actual
8673 value does not matter.
8674 (LIST_END_P): Remove unused macro and its bogus comment.
8675 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8677 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8678 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8679 implementation.
8680 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8681 We prefer signed types, and the value cannot exceed the EMACS_INT
8682 range anyway (because otherwise the length would not be representable).
8683 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8684 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8685 This avoids a GCC warning when WIDE_EMACS_INT.
8687 * indent.c (sane_tab_width): New function.
8688 (current_column, scan_for_column, Findent_to, position_indentation)
8689 (compute_motion): Use it. This is just for clarity.
8690 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8692 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8694 * lisp.h (lint_assume): New macro.
8695 * composite.c (composition_gstring_put_cache):
8696 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8698 * editfns.c, insdel.c:
8699 Omit unnecessary forward decls, to simplify future changes.
8701 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8703 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8705 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8706 Use much-faster test for byte-length change.
8707 Don't assume string byte-length fits in 'int'.
8708 Check that character arg fits in 'int'.
8709 (mapcar1): Declare byte as byte, for clarity.
8711 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
8713 * fns.c (concat): Catch string overflow earlier.
8714 Do not rely on integer wraparound.
8716 * dispextern.h (struct it.overlay_strings_charpos)
8717 (struct it.selective): Now EMACS_INT, not int.
8718 * xdisp.c (forward_to_next_line_start)
8719 (back_to_previous_visible_line_start)
8720 (reseat_at_next_visible_line_start, next_element_from_buffer):
8721 Don't arbitrarily truncate the value of 'selective' to int.
8723 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
8725 * composite.c: Don't truncate sizes to 'int'.
8726 (composition_gstring_p, composition_reseat_it)
8727 (composition_adjust_point): Use EMACS_INT, not int.
8728 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
8729 not EMACS_UINT, for indexes.
8731 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
8733 * buffer.c: Include <verify.h>.
8734 (struct sortvec.priority, struct sortstr.priority):
8735 Now EMACS_INT, not int.
8736 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
8737 (struct sortstr.size, record_overlay_string)
8738 (struct sortstrlist.size, struct sortlist.used):
8739 Don't truncate size to int.
8740 (record_overlay_string): Check for size-calculation overflow.
8741 (init_buffer_once): Check at compile-time, not run-time.
8743 2011-06-22 Jim Meyering <meyering@redhat.com>
8745 Don't leak an XBM-image-sized buffer
8746 * image.c (xbm_load): Free the image buffer after using it.
8748 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
8750 Port to Sun C.
8751 * composite.c (find_automatic_composition): Omit needless 'return 0;'
8752 that Sun C diagnosed.
8753 * fns.c (secure_hash): Fix pointer signedness issue.
8754 * intervals.c (static_offset_intervals): New function.
8755 (offset_intervals): Use it.
8757 2011-06-21 Leo Liu <sdl.web@gmail.com>
8759 * deps.mk (fns.o):
8760 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
8761 sha512.h.
8763 * fns.c (secure_hash): Rename from crypto_hash_function and change
8764 the first arg to accept symbols.
8765 (Fsecure_hash): New primitive.
8766 (syms_of_fns): New symbols.
8768 2011-06-20 Deniz Dogan <deniz@dogan.se>
8770 * process.c (Fset_process_buffer): Clarify return value in
8771 docstring.
8773 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
8775 * dispnew.c (add_window_display_history): Use BVAR.
8777 * xdisp.c (debug_method_add): Use BVAR.
8778 (check_window_end, dump_glyph_matrix, dump_glyph)
8779 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
8781 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
8782 Likewise.
8784 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
8785 check till after the cache is created in init_frame_faces.
8787 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
8789 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
8791 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
8793 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
8794 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
8795 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
8797 Improve buffer-overflow checking (Bug#8873).
8798 * fileio.c (Finsert_file_contents):
8799 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
8800 Remove the old (too-loose) buffer overflow checks.
8801 They weren't needed, since make_gap checks for buffer overflow.
8802 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
8803 The old code merely checked for Emacs fixnum overflow, and relied
8804 on undefined (wraparound) behavior. The new code avoids undefined
8805 behavior, and also checks for ptrdiff_t and/or size_t overflow.
8807 * editfns.c (Finsert_char): Don't dump core with very negative counts.
8808 Tune. Don't use wider integers than needed. Don't use alloca.
8809 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
8811 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
8813 * insdel.c, lisp.h (buffer_overflow): New function.
8814 (insert_from_buffer_1, replace_range, replace_range_2):
8815 * insdel.c (make_gap_larger):
8816 * editfns.c (Finsert_char):
8817 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
8819 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
8821 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
8823 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
8825 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
8826 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
8828 * fileio.c: Don't assume EMACS_INT fits in off_t.
8829 (emacs_lseek): New static function.
8830 (Finsert_file_contents, Fwrite_region): Use it.
8831 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
8833 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
8835 * fns.c: Don't overflow int when computing a list length.
8836 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
8837 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
8838 truncation on 64-bit hosts. Check for QUIT every
8839 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
8840 faster and is responsive enough.
8841 (Flength): Report an error instead of overflowing an integer.
8842 (Fsafe_length): Return a float if the value is not representable
8843 as a fixnum. This shouldn't happen except in contrived situations.
8844 (Fnthcdr, Fsort): Don't assume list length fits in int.
8845 (Fcopy_sequence): Don't assume vector length fits in int.
8847 * alloc.c: Check that resized vectors' lengths fit in fixnums.
8848 (header_size, word_size): New constants.
8849 (allocate_vectorlike): Don't check size overflow here.
8850 (allocate_vector): Check it here instead, since this is the only
8851 caller of allocate_vectorlike that could cause overflow.
8852 Check that the new vector's length is representable as a fixnum.
8854 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
8855 The previous code was bogus. For example, next_almost_prime (32)
8856 returned 39, which is undesirable as it is a multiple of 3; and
8857 next_almost_prime (24) returned 25, which is a multiple of 5 so
8858 why was the code bothering to check for multiples of 7?
8860 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
8862 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
8864 Variadic C functions now count arguments with ptrdiff_t.
8865 This partly undoes my 2011-03-30 change, which replaced int with size_t.
8866 Back then I didn't know that the Emacs coding style prefers signed int.
8867 Also, in the meantime I found a few more instances where arguments
8868 were being counted with int, which may truncate counts on 64-bit
8869 machines, or EMACS_INT, which may be unnecessarily wide.
8870 * lisp.h (struct Lisp_Subr.function.aMANY)
8871 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
8872 Arg counts are now ptrdiff_t, not size_t.
8873 All variadic functions and their callers changed accordingly.
8874 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
8875 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
8876 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
8877 * callint.c (Fcall_interactively): Check arg count for overflow,
8878 to avoid potential buffer overrun. Use signed char, not 'int',
8879 for 'varies' array, so that we needn't bother to check its size
8880 calculation for overflow.
8881 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
8882 * eval.c (apply_lambda):
8883 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
8884 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
8885 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
8887 * callint.c (Fcall_interactively): Don't use index var as event count.
8889 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
8890 * mem-limits.h (SIZE): Remove; no longer used.
8892 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
8894 Remove unnecessary casts.
8895 * xterm.c (x_term_init):
8896 * xfns.c (x_set_border_pixel):
8897 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
8898 These aren't needed now that we assume ANSI C.
8900 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
8901 It's more likely to cause problems (due to unsigned overflow)
8902 than to cure them.
8904 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
8906 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
8908 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
8910 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
8912 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
8914 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
8916 GLYPH_CODE_FACE returns EMACS_INT, not int.
8917 * dispextern.h (merge_faces):
8918 * xfaces.c (merge_faces):
8919 * xdisp.c (get_next_display_element, next_element_from_display_vector):
8920 Don't assume EMACS_INT fits in int.
8922 * character.h (CHAR_VALID_P): Remove unused parameter.
8923 * fontset.c, lisp.h, xdisp.c: All uses changed.
8925 * editfns.c (Ftranslate_region_internal): Omit redundant test.
8927 * fns.c (concat): Minor tuning based on overflow analysis.
8928 This doesn't fix any bugs. Use int to hold character, instead
8929 of constantly refetching from Emacs object. Use XFASTINT, not
8930 XINT, for value known to be a character. Don't bother comparing
8931 a single byte to 0400, as it's always less.
8933 * floatfns.c (Fexpt):
8934 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
8936 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
8937 for characters.
8939 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
8941 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
8942 Without this fix, on a 64-bit host (aset S 0 4294967386) would
8943 incorrectly succeed when S was a string, because 4294967386 was
8944 truncated before it was used.
8946 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
8947 Otherwise, an out-of-range integer could cause undefined behavior
8948 on a 64-bit host.
8950 * composite.c: Use int, not EMACS_INT, for characters.
8951 (fill_gstring_body, composition_compute_stop_pos): Use int, not
8952 EMACS_INT, for values that are known to be in character range.
8953 This doesn't fix any bugs but is the usual style inside Emacs and
8954 may generate better code on 32-bit machines.
8956 Make sure a 64-bit char is never passed to ENCODE_CHAR.
8957 This is for reasons similar to the recent CHAR_STRING fix.
8958 * charset.c (Fencode_char): Check that character arg is actually
8959 a character. Pass an int to ENCODE_CHAR.
8960 * charset.h (ENCODE_CHAR): Verify that the character argument is no
8961 wider than 'int', as a compile-time check to prevent future regressions
8962 in this area.
8964 * character.c (char_string): Remove unnecessary casts.
8966 Make sure a 64-bit char is never passed to CHAR_STRING.
8967 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
8968 by silently ignoring the top 32 bits, allowing some values
8969 that were far too large to be valid characters.
8970 * character.h: Include <verify.h>.
8971 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
8972 arguments are no wider than unsigned, as a compile-time check
8973 to prevent future regressions in this area.
8974 * data.c (Faset):
8975 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
8976 (Fsubst_char_in_region):
8977 * fns.c (concat):
8978 * xdisp.c (decode_mode_spec_coding):
8979 Adjust to CHAR_STRING's new requirement.
8980 * editfns.c (Finsert_char, Fsubst_char_in_region):
8981 * fns.c (concat): Check that character args are actually
8982 characters. Without this test, these functions did the wrong
8983 thing with wildly out-of-range values on 64-bit hosts.
8985 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
8986 These casts should not be needed on 32-bit hosts, either.
8987 * keyboard.c (read_char):
8988 * lread.c (Fload): Remove casts to unsigned.
8990 * lisp.h (UNSIGNED_CMP): New macro.
8991 This fixes comparison bugs on 64-bit hosts.
8992 (ASCII_CHAR_P): Use it.
8993 * casefiddle.c (casify_object):
8994 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
8995 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
8996 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
8997 * dispextern.h (FACE_FROM_ID):
8998 * keyboard.c (read_char): Use UNSIGNED_CMP.
9000 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9001 not to EMACS_INT, to avoid GCC warning.
9003 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9005 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9006 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9007 isn't needed on 32-bit machines.
9009 * buffer.c (Fgenerate_new_buffer_name):
9010 Use EMACS_INT for count, not int.
9011 (advance_to_char_boundary): Return EMACS_INT, not int.
9013 * data.c (Qcompiled_function): Now static.
9015 * window.c (window_body_lines): Now static.
9017 * image.c (gif_load): Rename local to avoid shadowing.
9019 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9020 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9021 * alloc.c (make_save_value): Integer argument is now of type
9022 ptrdiff_t, not int.
9023 (mark_object): Use ptrdiff_t, not int.
9024 * lisp.h (pD): New macro.
9025 * print.c (print_object): Use it.
9027 * alloc.c: Use EMACS_INT, not int, to count objects.
9028 (total_conses, total_markers, total_symbols, total_vector_size)
9029 (total_free_conses, total_free_markers, total_free_symbols)
9030 (total_free_floats, total_floats, total_free_intervals)
9031 (total_intervals, total_strings, total_free_strings):
9032 Now EMACS_INT, not int. All uses changed.
9033 (Fgarbage_collect): Compute overall total using a double, so that
9034 integer overflow is less likely to be a problem. Check for overflow
9035 when converting back to an integer.
9036 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9037 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9038 These were 'int' variables that could overflow on 64-bit hosts;
9039 they were never used, so remove them instead of repairing them.
9040 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9041 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9042 Previously, this ceilinged at INT_MAX, but that doesn't work on
9043 64-bit machines.
9044 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9046 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9047 (allocate_vectorlike): Check for ptrdiff_t overflow.
9048 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9049 when a (possibly-narrower) signed value would do just as well.
9050 We prefer using signed arithmetic, to avoid comparison confusion.
9052 * alloc.c: Catch some string size overflows that we were missing.
9053 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9054 for convenience in STRING_BYTES_MAX.
9055 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9056 The definition here is exact; the one in lisp.h was approximate.
9057 (allocate_string_data): Check for string overflow. This catches
9058 some instances we weren't catching before. Also, it catches
9059 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9060 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9061 and ptrdiff_t and EMACS_INT are both 64 bits.
9063 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9064 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9065 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9067 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9069 * alloc.c (Fmake_string): Check for out-of-range init.
9071 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9073 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9075 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
9077 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

9086 Call gtk_window_set_resizable if HAVE_GTK3.
9087 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9088 and height if HAVE_GTK3 (Bug#8505).
9089 (scroll_bar_width_for_theme): New variable.
9090 (update_theme_scrollbar_width): New function.
9091 (xg_get_default_scrollbar_width): Move code to
9092 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

9095 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
9097 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

9102 other_buffer.
9104 * window.c (temp_output_buffer_show): Call display_buffer with
9105 second argument Vtemp_buffer_show_specifiers and reset latter
9106 immediately after the call.
9107 (Vtemp_buffer_show_specifiers): New variable.
9108 (auto_window_vscroll_p, next_screen_context_lines)
9109 (Vscroll_preserve_screen_position): Remove leading asterisks from
9110 doc-strings.

9652 (bidi_level_of_next_char): Don't try to lookup the cache for the
9653 next/previous character if nothing is cached there yet, or if we
9654 were just reseat()'ed to a new position.

9705 * gnutls.c: Use Emacs's memory allocators.
9706 Without this change, the gnutls library would invoke malloc etc.
9707 directly, which causes problems on non-SYNC_INPUT hosts, and which
9708 runs afoul of improving memory_full behavior. (Bug#8761)
9709 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
9710 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
9711 xfree instead of the default malloc, realloc, free.
9712 (Fgnutls_boot): No need to check for memory allocation failure,
9713 since xmalloc does that for us.

9744 Check for integer overflow with large hash tables.
9745 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
9746 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
9747 (SXHASH_REDUCE): New macro.
9748 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
9749 Use it instead of discarding useful hash info with large hash values.
9750 (sxhash_float): New function.
9751 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
9752 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
9753 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
9754 Rewrite to use FIXNUM_BITS, as this simplifies things.
9755 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
9756 Adjust signatures to match updated version of code.
9757 (consing_since_gc): Now EMACS_INT, since a single hash table can

9807 Make it possible to run ./temacs.
9809 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
9810 syms_of_callproc does the same thing. Remove test for
9811 "initialized", do it in the caller.

9820 * data.c (Qbuffer): Don't make it static.
9821 (syms_of_data): Use DEFSYM.
9823 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9825 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
9826 (CCL_CODE_MIN): New macro.
9828 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
9830 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
9832 * eval.c (Qdebug): Now static.
9833 * lisp.h (Qdebug): Remove decl. This reverts a part of the
9834 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
9835 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
9837 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9839 * image.c: Various fixes to ImageMagick code comments.
9840 (Fimagemagick_types): Doc fix.
9842 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
9844 Minor fixes prompted by GCC 4.6.0 warnings.
9846 * xselect.c (converted_selections, conversion_fail_tag): Now static.
9848 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
9849 (x_clipboard_manager_save_all): Move extern decl to ...
9850 * xterm.h: ... here, so that it can be checked for consistency.
9852 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9854 * xselect.c (x_clipboard_manager_save_frame)
9855 (x_clipboard_manager_save_all): New functions.
9856 (Fx_clipboard_manager_save): Lisp function deleted.
9858 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
9859 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
9861 * xterm.h: Update prototype.
9863 2011-05-28 William Xu <william.xwl@gmail.com>
9865 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
9866 exiting (Bug#8239).
9868 2011-05-28 Jim Meyering <meyering@redhat.com>
9870 Avoid a sign-extension bug in crypto_hash_function.
9871 * fns.c (to_uchar): Define.
9872 (crypto_hash_function): Use it to convert some newly-signed
9873 variables to unsigned, to avoid sign-extension bugs. For example,
9874 without this change, (md5 "truc") would evaluate to
9875 45723a2aff78ff4fff7fff1114760e62 rather than the expected
9876 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
9877 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
9879 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9881 Integer overflow fixes.
9883 * dbusbind.c: Serial number integer overflow fixes.
9884 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
9885 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
9886 to hold a serial number that is too large for a fixnum.
9887 (Fdbus_method_return_internal, Fdbus_method_error_internal):
9888 Check for serial numbers out of range. Decode any serial number
9889 that was so large that it became a float. (Bug#8722)
9891 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
9892 (Fdbus_call_method, Fdbus_call_method_asynchronously):
9893 Use XFASTINT rather than XUINT when numbers are nonnegative.
9894 (xd_append_arg, Fdbus_method_return_internal):
9895 (Fdbus_method_error_internal): Likewise. Also, for unsigned
9896 arguments, check that Lisp number is nonnegative, rather than
9897 silently wrapping negative numbers around. (Bug#8722)
9898 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
9899 (Bug#8722)
9901 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
9903 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
9905 ccl: Add integer overflow checks.
9906 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
9907 (IN_INT_RANGE): New macros.
9908 (ccl_driver): Use them to check for integer overflow when
9909 decoding a CCL program. Many of the new checks are whether XINT (x)
9910 fits in int; it doesn't always, on 64-bit hosts. The new version
9911 doesn't catch all possible integer overflows, but it's an
9912 improvement. (Bug#8719)
9914 * alloc.c (make_event_array): Use XINT, not XUINT.
9915 There's no need for unsigned here.
9917 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
9918 This follows up to the 2011-05-06 change that substituted uintptr_t
9919 for EMACS_INT. This case wasn't caught back then.
9921 Rework Fformat to avoid integer overflow issues.
9922 * editfns.c: Include <float.h> unconditionally, as it's everywhere
9923 now (part of C89). Include <verify.h>.
9924 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
9925 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
9926 (Fformat): Avoid the prepass trying to compute sizes; it was only
9927 approximate and thus did not catch overflow reliably. Instead, walk
9928 through the format just once, formatting and computing sizes as we go,
9929 checking for integer overflow at every step, and allocating a larger
9930 buffer as needed. Keep track separately whether the format is
9931 multibyte. Keep only the most-recently calculated precision, rather
9932 than them all. Record whether each argument has been converted to
9933 string. Use EMACS_INT, not int, for byte and char and arg counts.
9934 Support field widths and precisions larger than INT_MAX. Avoid
9935 sprintf's undefined behavior with conversion specifications such as %#d
9936 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
9937 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
9938 formatting out-of-range floating point numbers with int
9939 formats. (Bug#8668)
9941 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
9943 * data.c: Avoid integer truncation in expressions involving floats.
9944 * data.c: Include <intprops.h>.
9945 (arith_driver): When there's an integer overflow in an expression
9946 involving floating point, convert the integers to floating point
9947 so that the resulting value does not suffer from catastrophic
9948 integer truncation. For example, on a 64-bit host (* 4
9949 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
9950 Do not rely on undefined behavior after integer overflow.
9952 merge count_size_as_multibyte, parse_str_to_multibyte
9953 * character.c, character.h (count_size_as_multibyte):
9954 Rename from parse_str_to_multibyte; all uses changed.
9955 Check for integer overflow.
9956 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
9957 since it's now a duplicate of the other. This is more of
9958 a character than a buffer op, so better that it's in character.c.
9959 * fns.c, print.c: Adjust to above changes.
9961 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
9963 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
9965 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9967 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9968 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
9969 (x_clipboard_manager_save): Now static.
9970 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
9972 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9973 (crypto_hash_function): Now static.
9974 Fix pointer signedness problems. Avoid unnecessary initializations.
9976 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
9978 * termhooks.h (Vselection_alist): Make it terminal-local.
9980 * terminal.c (create_terminal): Initialize it.
9982 * xselect.c: Support for clipboard managers.
9983 (Vselection_alist): Move to termhooks.h as terminal-local var.
9984 (LOCAL_SELECTION): New macro.
9985 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
9986 (symbol_to_x_atom): Remove gratuitous arg.
9987 (x_handle_selection_request, lisp_data_to_selection_data)
9988 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
9989 (x_own_selection, x_get_local_selection, x_convert_selection):
9990 New arg, specifying work frame. Use terminal-local Vselection_alist.
9991 (some_frame_on_display): Delete unused function.
9992 (Fx_own_selection_internal, Fx_get_selection_internal)
9993 (Fx_disown_selection_internal, Fx_selection_owner_p)
9994 (Fx_selection_exists_p): New optional frame arg.
9995 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
9996 (x_handle_selection_clear): Don't treat other terminals with the
9997 same keyboard specially. Use the terminal-local Vselection_alist.
9998 (x_clear_frame_selections): Use Frun_hook_with_args.
10000 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10002 * xterm.h: Add support for those atoms.
10004 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10006 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10007 (converted_selections, conversion_fail_tag): New global variables.
10008 (x_selection_request_lisp_error): Free the above.
10009 (x_get_local_selection): Remove unnecessary code.
10010 (x_reply_selection_request): Args changed; handle arbitrary array
10011 of converted selections stored in converted_selections.
10012 Separate the XChangeProperty and SelectionNotify steps.
10013 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10014 (x_convert_selection): New function.
10015 (x_handle_selection_event): Simplify.
10016 (x_get_foreign_selection): Don't ignore incoming requests while
10017 waiting for an answer; this will fail when we implement
10018 SAVE_TARGETS, and seems unnecessary anyway.
10019 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10020 (Vx_sent_selection_functions): Doc fix.
10022 2011-05-26 Leo Liu <sdl.web@gmail.com>
10024 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10026 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10028 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10030 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10031 for fringe update if it has periodic bitmap.
10032 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10033 and fringe_bitmap_periodic_p.
10035 * fringe.c (get_fringe_bitmap_data): New function.
10036 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10037 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10038 row. Mark glyph row for fringe update if periodicity changed.
10040 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10041 for fringe update unless it has periodic bitmap.
10043 2011-05-25 Kenichi Handa <handa@m17n.org>
10045 * xdisp.c (get_next_display_element): Set correct it->face_id for
10046 a static composition.
10048 2011-05-24 Leo Liu <sdl.web@gmail.com>
10050 * deps.mk (fns.o):
10051 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10053 * fns.c (crypto_hash_function, Fsha1): New function.
10054 (Fmd5): Use crypto_hash_function.
10055 (syms_of_fns): Add Ssha1.
10057 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10059 * gnutls.c: Remove unused macros.
10060 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10061 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10062 Remove macros that are defined and never used.
10063 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10065 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10067 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10068 (Fx_get_selection_internal): Minor cleanup.
10069 (Fx_own_selection_internal): Rename arguments for consistency with
10070 select.el.
10072 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10074 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10076 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10078 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10080 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10082 * dispnew.c (scrolling_window): Don't exclude the case that the
10083 last enabled row in the desired matrix touches the bottom boundary.
10085 2011-05-21 Glenn Morris <rgm@gnu.org>
10087 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10088 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10089 and add some more files.
10091 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10093 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10094 report_file_error introduced by the change from 2011-05-07.
10096 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10098 * systime.h (Time): Define only if emacs is defined.
10099 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10100 where the include path doesn't have X11/X.h by default. See
10101 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10103 2011-05-20 Kenichi Handa <handa@m17n.org>
10105 * composite.c (find_automatic_composition): Fix previous change.
10107 2011-05-20 Glenn Morris <rgm@gnu.org>
10109 * lisp.mk: New file, split from Makefile.in.
10110 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10111 (shortlisp): Remove.
10112 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10114 2011-05-19 Glenn Morris <rgm@gnu.org>
10116 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10117 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10118 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10119 (lisp): Set the order to that of loadup.el.
10120 (shortlisp): Make it a copy of $lisp.
10121 (SOME_MACHINE_LISP): Remove.
10122 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10123 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10125 2011-05-18 Kenichi Handa <handa@m17n.org>
10127 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10128 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10129 (find_automatic_composition): Mostly rewrite for efficiency.
10131 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10133 * makefile.w32-in: Update dependencies.
10135 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10137 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10138 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10140 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10142 Fix some integer overflow issues, such as string length overflow.
10144 * insdel.c (count_size_as_multibyte): Check for string overflow.
10146 * character.c (lisp_string_width): Check for string overflow.
10147 Use EMACS_INT, not int, for string indexes and lengths; in
10148 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10149 the resulting string length overflows an EMACS_INT; instead,
10150 report a string overflow if no precision given. When checking for
10151 precision exhaustion, use a check that cannot possibly have
10152 integer overflow. (Bug#8675)
10153 * character.h (lisp_string_width): Adjust to new signature.
10155 * alloc.c (string_overflow): New function.
10156 (Fmake_string): Use it. This doesn't change behavior, but saves
10157 a few bytes and will simplify future changes.
10158 * character.c (string_escape_byte8): Likewise.
10159 * lisp.h (string_overflow): New decl.
10161 Fixups, following up to the user-interface timestamp change.
10162 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10163 for UI timestamps, instead of unsigned long.
10164 * msdos.c (mouse_get_pos): Likewise.
10165 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10166 * w32gui.h (Time): Define by including "systime.h" rather than by
10167 declaring it ourselves. (Bug#8664)
10169 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10170 * image.c (clear_image_cache): Likewise.
10172 * term.c (term_mouse_position): Don't assume time_t wraparound.
10174 Be more systematic about user-interface timestamps.
10175 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10176 and sometimes 'EMACS_UINT', to represent these timestamps.
10177 This change causes it to use 'Time' uniformly, as that's what X uses.
10178 This makes the code easier to follow, and makes it easier to catch
10179 integer overflow bugs such as Bug#8664.
10180 * frame.c (Fmouse_position, Fmouse_pixel_position):
10181 Use Time, not unsigned long, for user-interface timestamps.
10182 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10183 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10184 * keyboard.h (last_event_timestamp): Likewise.
10185 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10186 * menu.h (xmenu_show): Likewise.
10187 * term.c (term_mouse_position): Likewise.
10188 * termhooks.h (struct input_event.timestamp): Likewise.
10189 (struct terminal.mouse_position_hook): Likewise.
10190 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10191 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10192 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10193 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10194 what it was before.
10195 * menu.h, termhooks.h: Include "systime.h", for Time.
10197 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10198 Don't assume that the difference between two unsigned long values
10199 can fit into an integer. At this point, we know button_down_time
10200 <= event->timestamp, so the difference must be nonnegative, so
10201 there's no need to cast the result if double-click-time is
10202 nonnegative, as it should be; check that it's nonnegative, just in
10203 case. This bug is triggered when events are more than 2**31 ms
10204 apart (about 25 days). (Bug#8664)
10206 * xselect.c (last_event_timestamp): Remove duplicate decl.
10207 (x_own_selection): Remove needless cast to unsigned long.
10209 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10210 that always fit in int. Use a sentinel instead of a counter, to
10211 avoid a temp and to allay GCC's concerns about possible int overflow.
10212 * frame.h (struct frame): Use int for menu_bar_items_used
10213 instead of EMACS_INT, since it always fits in int.
10215 * menu.c (grow_menu_items): Check for int overflow.
10217 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10219 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10220 Before, the code was not consistent. These values cannot exceed
10221 2**31 - 1 so there's no need to make them unsigned.
10222 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10223 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10224 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10225 as modifiers.
10226 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10228 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10229 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10230 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10231 presumably because the widths might not match.
10233 * window.c (size_window): Avoid needless test at loop start.
10235 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10237 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10239 2011-05-12 Drew Adams <drew.adams@oracle.com>
10241 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10243 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10245 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10246 `width' to `bar_area_x' and `bar_area_width', respectively.
10247 (x_scroll_run): Take account of fringe background extension.
10249 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10250 Rename local vars `left' and `width' to `bar_area_x' and
10251 `bar_area_width', respectively.
10252 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10253 background extension.
10255 2011-05-10 Jim Meyering <meyering@redhat.com>
10257 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10259 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10261 * image.c (Finit_image_library): Return t for built-in image types,
10262 like pbm and xbm. (Bug#8640)
10264 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10266 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10268 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10270 * w32console.c (Fset_screen_color): Doc fix.
10271 (Fget_screen_color): New function.
10272 (syms_of_ntterm): Defsubr it.
10274 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10275 unlink the temporary file if Fcall_process didn't create it in the
10276 first place.
10277 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10278 child process will be redirected to a file specified with `:file'.
10279 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10280 cue to call_process_cleanup not to close that handle.
10282 2011-05-07 Ben Key <bkey76@gmail.com>
10284 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10285 one of two shell specific rules, either bootstrap-temacs-CMD or
10286 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10287 to the previous implementation of the bootstrap-temacs rule.
10288 The bootstrap-temacs-CMD rule is similar to the previous
10289 implementation of the bootstrap-temacs rule except that it
10290 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10291 variable.
10293 These changes, along with some changes to nt/configure.bat,
10294 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10295 earlier fix to add support for --cflags and --ldflags options
10296 that include quotes so that it works whether make uses cmd or
10297 sh as the shell.
10299 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10301 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10302 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10303 is a constant.
10304 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10305 a string. Handle both cases.
10306 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10307 (Fdbus_register_method): Use Qinvalid_function.
10309 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10311 * makefile.w32-in: Update dependencies.
10312 (LISP_H): Add inttypes.h and stdin.h.
10313 (PROCESS_H): Add unistd.h.
10315 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10317 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10318 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10320 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10322 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10324 * term.c (vfatal): Remove stray call to va_end.
10325 It's not needed and the C Standard doesn't allow it here anyway.
10327 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10328 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10330 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10331 bytes.
10333 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10335 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10337 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10339 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10341 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10343 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10344 * charset.c (Fdefine_charset_internal): Don't initialize
10345 charset.code_space[15]. The value was garbage, on hosts with
10346 32-bit int (Bug#8600).
10348 * lread.c (read_integer): Be more consistent with string-to-number.
10349 Use string_to_number to do the actual conversion; this avoids
10350 rounding errors and fixes some other screwups. Without this fix,
10351 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10352 (digit_to_number): Move earlier, for benefit of read_integer.
10353 Return -1 if the digit is out of range for the base, -2 if it is
10354 not a digit in any supported base. (Bug#8602)
10356 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10358 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10359 to match comment at start of function. This also removes a
10360 GCC warning about overflow in a 32+64-bit port.
10362 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10364 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10365 Reported by Stefan Monnier in
10366 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10367 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10368 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10370 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10371 (EMACS_UINTPTR): Likewise, with uintptr_t.
10373 * lisp.h: Prefer 64-bit EMACS_INT if available.
10374 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10375 on 32-bit hosts that have 64-bit int, so that they can access
10376 large files.
10377 However, temporarily disable this change unless the temporary
10378 symbol WIDE_EMACS_INT is defined.
10380 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10382 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10383 This removes an assumption that EMACS_INT and long are the same
10384 width as pointers. The assumption is true for Emacs porting targets
10385 now, but we want to make other targets possible.
10386 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10387 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10388 In the rest of the code, change types of integers that hold casted
10389 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10390 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10391 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10392 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10393 No need to cast type when ORing.
10394 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10395 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10396 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10397 assume EMACS_INT is the same width as char *.
10398 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10399 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10400 Remove no-longer-needed casts.
10401 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10402 (xg_tool_bar_help_callback, xg_make_tool_item):
10403 Use EMACS_INTPTR to hold an integer
10404 that will be cast to void *; this can avoid a GCC warning
10405 if EMACS_INT is not the same width as void *.
10406 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10407 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10408 (current_message_1, set_message_1):
10409 Use a local to convert to proper width without a cast.
10410 * xmenu.c (dialog_selection_callback): Likewise.
10412 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10413 Also, don't assume VALBITS / RAND_BITS is less than 5,
10414 and don't rely on undefined behavior when shifting a 1 left into
10415 the sign bit.
10416 * lisp.h (get_random): Change signature to match.
10418 * lread.c (hash_string): Use size_t, not int, for hash computation.
10419 Normally we prefer signed values; but hashing is special, because
10420 it's better to use unsigned division on hash table sizes so that
10421 the remainder is nonnegative. Also, size_t is the natural width
10422 for hashing into memory. The previous code used 'int', which doesn't
10423 retain enough info to hash well into very large tables.
10424 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10426 * dbusbind.c: Don't possibly lose pointer info when converting.
10427 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10428 Use XPNTR rather than XHASH, so that the high-order bits of
10429 the pointer aren't lost when converting through void *.
10431 * eval.c (Fautoload): Don't double-shift a pointer.
10433 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10435 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10437 * gnutls.c (DEF_GNUTLS_FN):
10438 * image.c (DEF_IMGLIB_FN): Make function pointers static.
10440 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
10442 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
10443 marker. (Bug#8610)
10445 2011-05-05 Eli Zaretskii <eliz@gnu.org>
10447 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
10448 New version that can reserve upto 2GB of heap space.
10450 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
10452 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
10454 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
10456 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
10457 `gnutls_certificate_set_x509_key_file'.
10459 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
10461 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
10462 Update dependencies.
10464 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10466 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
10467 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
10468 Remove unused parameter `fildes'.
10469 * process.c (read_process_output, send_process): Don't pass it.
10471 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10473 Fix previous change: the library cache is defined in w32.c.
10474 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
10475 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
10477 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10479 Implement dynamic loading of GnuTLS on Windows.
10481 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
10482 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
10483 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10484 Declare.
10486 * gnutls.c (Qgnutls_dll): Define.
10487 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
10488 (gnutls_*): Declare function pointers.
10489 (init_gnutls_functions): New function to initialize function pointers.
10490 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
10491 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
10492 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10493 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
10494 (emacs_gnutls_write, emacs_gnutls_read)
10495 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
10496 (Fgnutls_available_p): New function.
10497 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
10498 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
10499 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
10501 * image.c: Include w32.h.
10502 (Vimage_type_cache): Delete.
10503 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
10504 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
10505 (w32_delayed_load): Move to w32.c.
10507 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
10509 * w32.c (QCloaded_from, Vlibrary_cache): Define.
10510 (w32_delayed_load): Move from image.c. When loading a library, record
10511 its filename in the :loaded-from property of the library id.
10512 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
10513 Initialize and staticpro them.
10514 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
10516 * process.c: Include lisp.h before w32.h, not after.
10517 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10518 instead of gnutls_record_check_pending.
10520 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10522 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10524 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
10525 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
10526 as passed in.
10528 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
10530 * xterm.c (x_set_frame_alpha): Do not set property on anything
10531 else than FRAME_X_OUTER_WINDOW (Bug#8608).
10533 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10535 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
10537 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10539 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
10540 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

10546 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
10547 (Qgnutls_bootprop_callbacks_verify): Make static.
10549 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
10551 * callproc.c: Indentation fixup.
10553 * sysdep.c (wait_for_termination_1): Make static.
10554 (wait_for_termination, interruptible_wait_for_termination):
10555 Move after wait_for_termination_1.
10557 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
10559 * sysdep.c (interruptible_wait_for_termination): New function
10560 which is like wait_for_termination, but allows keyboard
10561 interruptions.
10563 * callproc.c (Fcall_process): Add (:file "file") as an option for
10564 the STDOUT buffer.
10565 (Fcall_process_region): Ditto.
10567 2011-04-30 Eli Zaretskii <eliz@gnu.org>
10569 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
10570 rather than `XVECTOR (FOO)->size'.
10572 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10573 inttypes.h, as a gnulib replacement is used if it not available in
10574 system headers.
10576 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10578 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
10579 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
10580 of MOST_POSITIVE_FIXNUM. (Bug#8528)

10583 will grow beyond MOST_POSITIVE_FIXNUM.
10584 (decode_coding_emacs_mule): Abort if there isn't enough place in

10586 space for up to 2 characters produced in a loop.
10587 (decode_coding_iso_2022): Abort if there isn't enough place in
10588 charbuf for the composition carryover bytes.
10590 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10592 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
10593 aborting when %lld or %lll format is passed.
10594 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
10595 %llo or %llx format is passed. (Bug#8545)
10597 * window.c (window_scroll_line_based): Use a marker instead of
10598 simple variables to record original value of point. (Bug#7952)
10600 * doprnt.c (doprnt): Fix the case where a multibyte sequence
10601 produced by %s or %c overflows available buffer space. (Bug#8545)
10603 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10605 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
10606 (SIZE_MAX): Move defn after all includes, as they might #define it.
10608 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

10617 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
10618 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
10620 2011-04-28 Eli Zaretskii <eliz@gnu.org>
10622 * doprnt.c (doprnt): Don't return value smaller than the buffer
10623 size if the message was truncated. (Bug#8545).
10625 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10627 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
10628 (Fx_window_property): #if-0 the whole functions, not just the bodies.
10630 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10632 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
10634 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
10636 * makefile.w32-in: Update dependencies.
10638 2011-04-27 Eli Zaretskii <eliz@gnu.org>
10640 Improve `doprnt' and its usage. (Bug#8545)
10641 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
10642 `format_end'. Remove support for %l as a conversion specifier.
10643 Don't use xrealloc. Improve diagnostics when the %l size modifier
10644 is used. Update the commentary.
10646 * eval.c (verror): Simplify calculation of size_t.
10648 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
10649 messages.
10651 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
10653 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10654 change.
10656 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10658 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10659 This makes this file independent of the recent pseudovector change.
10661 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
10663 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10665 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10666 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10667 Remove unused local.
10668 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10670 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
10671 GCC 4.6.0 optimizes based on type-based alias analysis.
10672 For example, if b is of type struct buffer * and v of type struct
10673 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10674 != &v->size, and therefore "v->size = 1; b->size = 2; return
10675 v->size;" must therefore return 1. This assumption is incorrect
10676 for Emacs, since it type-puns struct Lisp_Vector * with many other
10677 types. To fix this problem, this patch adds a new type struct
10678 vectorlike_header that documents the constraints on layout of vectors
10679 and pseudovectors, and helps optimizing compilers not get fooled
10680 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
10681 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10682 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10683 the size member.
10684 (XSETPVECTYPE): Rewrite in terms of new macro.
10685 (XSETPVECTYPESIZE): New macro, specifying both type and size.
10686 This is a bit clearer, and further avoids the possibility of
10687 undesirable aliasing.
10688 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10689 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10690 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10691 since Lisp_Subr is a special case (no "next" field).
10692 (ASIZE): Now uses header.size rather than size.
10693 All previous uses of XVECTOR (foo)->size replaced to use this macro,
10694 to avoid the hassle of writing XVECTOR (foo)->header.size.
10695 (struct vectorlike_header): New type.
10696 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10697 object, to help avoid aliasing.
10698 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10699 (SUBRP): Likewise, since Lisp_Subr is a special case.
10700 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10701 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10702 (struct Lisp_Hash_Table): Combine first two members into a single
10703 struct vectorlike_header member. All uses of "size" and "next" members
10704 changed to be "header.size" and "header.next".
10705 * buffer.h (struct buffer): Likewise.
10706 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
10707 * frame.h (struct frame): Likewise.
10708 * process.h (struct Lisp_Process): Likewise.
10709 * termhooks.h (struct terminal): Likewise.
10710 * window.c (struct save_window_data, struct saved_window): Likewise.
10711 * window.h (struct window): Likewise.
10712 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
10713 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
10714 * buffer.c (init_buffer_once): Likewise.
10715 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
10716 special case.
10717 * process.c (Fformat_network_address): Use local var for size,
10718 for brevity.
10720 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
10722 Make the Lisp reader and string-to-float more consistent (Bug#8525)
10723 * data.c (atof): Remove decl; no longer used or needed.
10724 (digit_to_number): Move to lread.c.
10725 (Fstring_to_number): Use new string_to_number function, to be
10726 consistent with how the Lisp reader treats infinities and NaNs.
10727 Do not assume that floating-point numbers represent EMACS_INT
10728 without losing information; this is not true on most 64-bit hosts.
10729 Avoid double-rounding errors, by insisting on integers when
10730 parsing non-base-10 numbers, as the documentation specifies.
10731 * lisp.h (string_to_number): New decl, replacing ...
10732 (isfloat_string): Remove.
10733 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
10734 (read1): Do not accept +. and -. as integers; this
10735 appears to have been a coding error. Similarly, do not accept
10736 strings like +-1e0 as floating point numbers. Do not report
10737 overflow for integer overflows unless the base is not 10 which
10738 means we have no simple and reliable way to continue.
10739 Break out the floating-point parsing into a new
10740 function string_to_number, so that Fstring_to_number parses
10741 floating point numbers consistently with the Lisp reader.
10742 (digit_to_number): Move here from data.c. Make it static inline.
10743 (E_CHAR, EXP_INT): Remove, replacing with ...
10744 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
10745 (string_to_number): New function, replacing isfloat_string.
10746 This function checks for valid syntax and produces the resulting
10747 Lisp float number too. Rework it so that string-to-number
10748 no longer mishandles examples like "1.0e+". Use strtoumax,
10749 so that overflow for non-base-10 numbers is reported only when
10750 there's no portable and simple way to convert to floating point.
10752 * textprop.c (set_text_properties_1): Rewrite for clarity,
10753 and to avoid GCC warning about integer overflow.
10755 * intervals.h (struct interval): Use EMACS_INT for members
10756 where EMACS_UINT might cause problems. See
10757 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
10758 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
10759 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
10760 All uses changed.
10761 (offset_intervals): Tell GCC not to worry about length overflow
10762 when negating a negative length.
10764 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
10765 (overrun_check_free): Likewise.
10767 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
10768 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
10769 word size.
10771 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10772 (gnutls_make_error): Rename local to avoid shadowing.
10773 (gnutls_emacs_global_deinit): ifdef out; not used.
10774 (Fgnutls_boot): Use const for pointer to readonly storage.
10775 Comment out unused local. Fix pointer signedness problems.
10777 * lread.c (openp): Don't stuff size_t into an 'int'.
10778 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
10779 about possible signed overflow.
10781 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10782 (GDK_KEY_g): Don't define if already defined.
10783 (xg_prepare_tooltip): Avoid pointer signedness problem.
10784 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
10786 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
10787 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
10789 * xfns.c (Fx_window_property): Simplify a bit,
10790 to make a bit faster and to avoid GCC 4.6.0 warning.
10791 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
10793 * fns.c (internal_equal): Don't assume size_t fits in int.
10795 * alloc.c (compact_small_strings): Tighten assertion a little.
10797 Replace pEd with more-general pI, and fix some printf arg casts.
10798 * lisp.h (pI): New macro, generalizing old pEd macro to other
10799 conversion specifiers. For example, use "...%"pI"d..." rather
10800 than "...%"pEd"...".
10801 (pEd): Remove. All uses replaced with similar uses of pI.
10802 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
10803 * alloc.c (check_pure_size): Don't overflow by converting size to int.
10804 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
10805 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
10806 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
10807 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
10808 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
10809 64-bit hosts.
10810 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
10811 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
10812 * print.c (safe_debug_print, print_object): Likewise.
10813 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
10814 to int.
10815 Use pI instead of if-then-else-abort. Use %p to avoid casts,
10816 avoiding the 0 flag, which is not portable.
10817 * process.c (Fmake_network_process): Use pI to avoid cast.
10818 * region-cache.c (pp_cache): Likewise.
10819 * xdisp.c (decode_mode_spec): Likewise.
10820 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
10821 behavior on 64-bit hosts with printf arg.
10822 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
10823 (x_stop_queuing_selection_requests): Likewise.
10824 (x_get_window_property): Don't truncate byte count to an 'int'
10825 when tracing.
10827 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
10828 here, since it parses constructs like leading '-' and spaces,
10829 which are not wanted; and it overflows with large numbers.
10830 Instead, simply match F[0-9]+, which is what is wanted anyway.
10832 * alloc.c: Remove unportable assumptions about struct layout.
10833 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
10834 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
10835 (allocate_vectorlike, make_pure_vector): Use the new macros,
10836 plus offsetof, to remove unportable assumptions about struct layout.
10837 These assumptions hold on all porting targets that I know of, but
10838 they are not guaranteed, they're easy to remove, and removing them
10839 makes further changes easier.
10841 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
10842 This doesn't fix a bug but makes the code clearer.
10843 (string_overrun_cookie): Now const. Use initializers that
10844 don't formally overflow signed char, to avoid warnings.
10845 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
10846 can cause Emacs to crash when string overrun checking is enabled.
10847 (allocate_buffer): Don't assume sizeof (struct buffer) is a
10848 multiple of sizeof (EMACS_INT); it need not be, if
10849 alignof(EMACS_INT) < sizeof (EMACS_INT).
10850 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
10852 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
10854 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
10856 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
10858 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
10859 supposed to be handshaking. (Bug#8556)
10860 Reported by Paul Eggert <eggert@cs.ucla.edu>.
10862 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
10864 * lisp.h (Qdebug): List symbol.
10865 * eval.c (Qdebug): Restore global linkage.
10866 * keyboard.c (debug-on-event): New variable.
10867 (handle_user_signal): Break into debugger when debug-on-event
10868 matches the current signal symbol.
10870 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
10872 * alloc.c (check_sblock, check_string_bytes)
10873 (check_string_free_list): Convert to standard C.
10875 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
10877 * w32.c (emacs_gnutls_push): Fix typo.
10879 2011-04-25 Eli Zaretskii <eliz@gnu.org>
10881 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
10882 "cast to pointer from integer of different size".
10884 Improve doprnt and its use in verror. (Bug#8545)
10885 * doprnt.c (doprnt): Document the set of format control sequences
10886 supported by the function. Use SAFE_ALLOCA instead of always
10887 using `alloca'.
10889 * eval.c (verror): Don't limit the buffer size at size_max-1, that
10890 is one byte too soon. Don't use xrealloc; instead xfree and
10891 xmalloc anew.
10893 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
10895 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
10896 callbacks stage.
10898 * gnutls.c: Renamed global_initialized to
10899 gnutls_global_initialized. Added internals for the
10900 :verify-hostname-error, :verify-error, and :verify-flags
10901 parameters of `gnutls-boot' and documented those parameters in the
10902 docstring. Start callback support.
10903 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
10904 unless a fatal error occurred. Call gnutls_alert_send_appropriate
10905 on error. Return error code.
10906 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
10907 (emacs_gnutls_read): Likewise.
10908 (Fgnutls_boot): Return handshake error code.
10909 (emacs_gnutls_handle_error): New function.
10910 (wsaerror_to_errno): Likewise.

10913 (emacs_gnutls_push): Likewise.
10915 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
10916 (emacs_gnutls_push): Likewise.
10918 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
10920 * process.c (wait_reading_process_output): Check if GnuTLS
10921 buffered some data internally if no FDs are set for TLS
10922 connections.

10930 * xdisp.c (handle_single_display_spec): Rename the
10931 display_replaced_before_p argument into display_replaced_p, to
10932 make it consistent with the commentary. Fix typos in the
10933 commentary.
10935 * textprop.c (syms_of_textprop): Remove dead code.
10936 (copy_text_properties): Delete obsolete commentary about an
10937 interface that was deleted long ago. Fix typos in the description
10938 of arguments.

10941 to changes in oldXMenu/XMenu.h from 2011-04-16.
10942 <menu_help_message, prev_menu_help_message>: Constify.
10943 (IT_menu_make_room): menu->help_text is now `const char **';
10944 adjust.

10947 to changes in oldXMenu/XMenu.h from 2011-04-16.
10948 (struct XMenu): Declare `help_text' `const char **'.
10950 * xfaces.c <Qunspecified>: Make extern again.
10952 * syntax.c: Include sys/types.h before including regex.h, as
10953 required by POSIX.
10955 * doc.c (get_doc_string): Improve the format passed to `error'.
10957 * doprnt.c (doprnt): Improve commentary.
10959 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
10961 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
10962 them with etags.
10964 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
10965 changes in globals.h immediately force recompilation.
10966 (TAGS): Depend on $(CURDIR)/m/intel386.h and
10967 $(CURDIR)/s/ms-w32.h.
10968 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
10970 * character.c (Fchar_direction): Function deleted.
10971 (syms_of_character): Don't defsubr it.
10972 <char-direction-table>: Deleted.
10974 2011-04-23 Eli Zaretskii <eliz@gnu.org>
10976 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
10977 * doprnt.c: Include limits.h.
10978 (SIZE_MAX): New macro.
10979 (doprnt): Return a size_t value. 2nd arg is now size_t.
10980 Many local variables are now size_t instead of int or unsigned.
10981 Improve overflow protection. Support `l' modifier for integer
10982 conversions. Support %l conversion. Don't assume an EMACS_INT
10983 argument for integer conversions and for %c.
10985 * lisp.h (doprnt): Restore prototype.
10987 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
10988 $(SRC)/character.h.
10990 * Makefile.in (base_obj): Add back doprnt.o.
10992 * deps.mk (doprnt.o): Add back prerequisites.
10993 (callint.o): Depend on character.h.
10995 * eval.c (internal_lisp_condition_case): Include the handler
10996 representation in the error message.
10997 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
10998 when breaking from the loop.
11000 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
11002 * callint.c (Fcall_interactively): When displaying error message
11003 about invalid control letter, pass the character's codepoint, not
11004 a pointer to its multibyte form. Improve display of the character
11005 in octal and display also its hex code.
11007 * character.c (char_string): Use %x to display the (unsigned)
11008 codepoint of an invalid character, to avoid displaying a bogus
11009 negative value.
11011 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11012 `error', not SYMBOL_NAME itself.
11014 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
11015 character arguments to `error'.
11017 * charset.c (check_iso_charset_parameter): Fix incorrect argument
11018 to `error' in error message about FINAL_CHAR argument. Make sure
11019 FINAL_CHAR is a character, and use %c when it is passed as
11020 argument to `error'.
11022 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11024 * s/ms-w32.h (localtime): Redirect to sys_localtime.
11026 * w32.c: Include <time.h>.
11027 (sys_localtime): New function.
11029 2011-04-23 Chong Yidong <cyd@stupidchicken.com>

11035 2011-04-23 Samuel Thibault <sthibault@debian.org> (tiny change)
11037 * sysdep.c (wait_for_termination): On GNU Hurd, kill returns -1 on
11038 zombies (Bug#8467).
11040 2011-04-19 Eli Zaretskii <eliz@gnu.org>
11042 * syntax.h (SETUP_SYNTAX_TABLE_FOR_OBJECT): Fix setting of
11043 gl_state.e_property when gl_state.object is Qt.
11045 * insdel.c (make_gap_larger): Remove limitation of buffer size
11046 to <= INT_MAX.
11048 2011-04-18 Chong Yidong <cyd@stupidchicken.com>
11050 * xdisp.c (lookup_glyphless_char_display)

11065 definition for no-X builds.
11067 2011-04-16 Paul Eggert <eggert@cs.ucla.edu>
11069 Static checks with GCC 4.6.0 and non-default toolkits.
11071 * s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF): Protoize decl.
11073 * process.c (keyboard_bit_set): Define only if SIGIO.
11074 (send_process_trap): Mark it with NO_RETURN if it doesn't return.
11075 (send_process): Repair possible setjmp clobbering.
11077 * s/usg5-4-common.h (SETUP_SLAVE_PTY): Don't pass extra arg to 'fatal'.
11079 * eval.c: Include <stdio.h>, for vsnprintf on non-GNU/Linux hosts.
11081 * data.c (arith_error): Mark with NO_RETURN if it doesn't return.
11083 * alloc.c (bytes_used_when_full, SPARE_MEMORY, BYTES_USED):
11084 Define only if needed.
11086 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
11087 by pacifying GCC about it. Maybe it's time to retire it?
11088 * xfaces.c (USG, __TIMEVAL__): Likewise.
11090 * dispextern.h (struct redisplay_interface): Rename param
11091 to avoid shadowing.
11092 * termhooks.h (struct terminal): Likewise.
11093 * xterm.c (xembed_send_message): Likewise.
11095 * insdel.c (make_gap_smaller): Define only if
11096 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
11098 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
11099 it.
11101 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
11102 so that we aren't warned about unused symbols.
11104 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
11106 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
11108 * xfns.c (x_real_positions): Mark locals as initialized.
11110 * xmenu.c (xmenu_show): Don't use uninitialized vars.
11112 * xterm.c: Fix problems found by static analysis with other toolkits.
11113 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
11114 (x_dispatch_event): Declare static if USE_GTK, and
11115 define if USE_GTK || USE_X_TOOLKIT.
11116 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
11117 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.

11209 * nsfont.m: Fixed bugs in ns_get_family and
11210 ns_descriptor_to_entity that were caused by using free to
11211 deallocate memory blocks that were allocated by xmalloc (via
11212 xstrdup). This caused Emacs to crash when compiled with
11213 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
11214 --enable-checking=xmallocoverrun). xfree is now used to
11215 deallocate these memory blocks.

11553 Now static.
11555 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
11556 * ccl.c (Vccl_program_table): Now static.
11557 (check_ccl_update): Remove; unused.
11559 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
11560 * category.h: ... from here.
11561 * category.c (check_category_table, set_category_set): Now static.

11564 * lisp.h: Remove these decls.
11566 * buffer.c (buffer_count): Remove unused var.
11568 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
11569 so that it's not optimized away.
11570 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
11571 * dispextern.h (bidi_dump_cached_states): Remove, since it's
11572 exported only to the debugger.
11574 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
11575 * atimer.h (run_all_atimers): Remove; not exported.
11577 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
11578 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
11579 was inaccessible from Lisp.
11580 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
11581 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
11583 alloc.c: Import and export fewer symbols, and remove unused items.
11584 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
11585 is defined.
11586 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
11587 it's not optimized away by whole-program optimization.
11588 (message_enable_multibyte, free_misc): Remove.
11589 (catchlist, handlerlist, mark_backtrace):
11590 Declare only if BYTE_MARK_STACK.
11591 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
11592 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
11593 (message_enable_multibyte): Remove decl.
11594 (free_misc, interval_free_list, float_block, float_block_index):
11595 (n_float_blocks, float_free_list, cons_block, cons_block_index):
11596 (cons_free_list, last_marked_index):
11597 Now static.
11598 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
11599 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
11600 (mark_backtrace): Define only if BYTE_MARK_STACK.
11601 * xdisp.c (message_enable_multibyte): Now static.
11603 Declare Lisp_Object Q* variables to be 'static' if not exported.
11604 This makes it easier for human readers (and static analyzers)
11605 to see whether these variables are used from other modules.
11606 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
11607 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
11608 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
11609 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

11611 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
11612 * xmenu.c, xselect.c:
11613 Declare Q* vars static if they are not used in other modules.
11614 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
11615 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
11616 Remove decls of unexported vars.
11617 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
11619 * lisp.h (DEFINE_FUNC): Make sname 'static'.
11621 Make Emacs functions such as Fatom 'static' by default.
11622 This makes it easier for human readers (and static analyzers)
11623 to see whether these functions can be called from other modules.
11624 DEFUN now defines a static function. To make the function external
11625 so that it can be used in other C modules, use the new macro DEFUE.
11626 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
11627 (Finit_image_library):
11628 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
11629 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
11630 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
11631 Remove decls, since these functions are now static.
11632 (Funintern, Fget_internal_run_time): New decls, since these functions
11633 were already external.
11635 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
11636 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
11637 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

11641 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
11642 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
11643 Mark functions with DEFUE instead of DEFUN,
11644 if they are used in other modules.
11645 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
11646 decls for now-static functions.
11647 * buffer.h (Fdelete_overlay): Remove decl.
11648 * callproc.c (Fgetenv_internal): Mark as internal.
11649 * composite.c (Fremove_list_of_text_properties): Remove decl.

11653 * doc.c (Fdocumntation_property): New forward static decl.
11654 * eval.c (Ffetch_bytecode): New forward static decl.
11655 (Funintern): Remove extern decl; now in .h file where it belongs.
11656 * fileio.c (Fmake_symbolic_link): New forward static decl.
11657 * image.c (Finit_image_library): New forward static decl.
11658 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
11659 * intervals.h (Fprevious_property_change):
11660 (Fremove_list_of_text_properties): Remove decls.
11661 * keyboard.c (Fthis_command_keys): Remove decl.
11662 (Fcommand_execute): New forward static decl.
11663 * keymap.c (Flookup_key): New forward static decl.
11664 (Fcopy_keymap): Now static.
11665 * keymap.h (Flookup_key): Remove decl.
11666 * process.c (Fget_process): New forward static decl.
11667 (Fprocess_datagram_address): Mark as internal.

11670 * textprop.c (Fprevious_property_change): New forward static decl.
11671 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
11672 Now internal.
11673 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
11674 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
11676 * editfns.c (Fformat): Remove unreachable code.
11678 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
11680 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
11681 change. (Bug#8496)
11683 2011-04-13 Eli Zaretskii <eliz@gnu.org>
11685 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
11686 when at ZV. (Bug#8487)
11688 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
11690 * charset.c (Fclear_charset_maps): Use xfree instead of free.
11691 (Bug#8437)
11692 * keyboard.c (parse_tool_bar_item): Likewise.
11693 * sound.c (sound_cleanup, alsa_close): Likewise.
11694 * termcap.c (tgetent): Likewise.
11695 * xfns.c (x_default_font_parameter): Likewise.
11696 * xsettings.c (read_and_apply_settings): Likewise.
11698 * alloc.c (overrun_check_malloc, overrun_check_realloc)
11699 (overrun_check_free): Protoize.
11701 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
11703 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
11704 since callers should never pass a negative size.
11705 Change the signature to match that of plain 'read' and 'write'; see
11706 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
11707 * lisp.h: Update prototypes of emacs_write and emacs_read.
11709 2011-04-11 Eli Zaretskii <eliz@gnu.org>
11711 * xdisp.c (redisplay_window): Don't try to determine the character
11712 position of the scroll margin if the window start point w->startp
11713 is outside the buffer's accessible region. (Bug#8468)
11715 2011-04-10 Eli Zaretskii <eliz@gnu.org>
11717 Fix write-region and its subroutines for buffers > 2GB.
11718 * fileio.c (a_write, e_write): Modify declaration of arguments and
11719 local variables to support buffers larger than 2GB.
11720 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
11722 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
11723 argument, local variables, and return value.
11725 * lisp.h: Update prototypes of emacs_write and emacs_read.
11727 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
11729 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
11731 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
11733 Fix more problems found by GCC 4.6.0's static checks.
11735 * xdisp.c (vmessage): Use a better test for character truncation.
11737 * charset.c (load_charset_map): <, not <=, for optimization,
11738 and to avoid potential problems with integer overflow.
11739 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
11740 * casetab.c (set_identity, shuffle): Likewise.
11741 * editfns.c (Fformat): Likewise.
11742 * syntax.c (skip_chars): Likewise.
11744 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
11745 This also lets GCC 4.6.0 generate slightly better loop code.
11747 * callint.c (Fcall_interactively): <, not <=, for optimization.
11748 (Fcall_interactively): Count the number of arguments produced,
11749 not the number of arguments given. This is simpler and lets GCC
11750 4.6.0 generate slightly better code.
11752 * ftfont.c: Distingish more carefully between FcChar8 and char.
11753 The previous code passed unsigned char * to a functions like
11754 strlen and xstrcasecmp that expect char *, which does not
11755 conform to the C standard.
11756 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
11757 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
11758 char * when the C standard requires it.
11760 * keyboard.c (read_char): Remove unused var.
11762 * eval.c: Port to Windows vsnprintf (Bug#8435).
11763 Include <limits.h>.
11764 (SIZE_MAX): Define if the headers do not.
11765 (verror): Do not give up if vsnprintf returns a negative count.
11766 Instead, grow the buffer. This ports to Windows vsnprintf, which
11767 does not conform to C99. Problem reported by Eli Zaretskii.
11768 Also, simplify the allocation scheme, by avoiding the need for
11769 calling realloc, and removing the ALLOCATED variable.
11771 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
11773 Remove invocations of doprnt, as Emacs now uses vsnprintf.
11774 But keep the doprint source code for now, as we might revamp it
11775 and use it again (Bug#8435).
11776 * lisp.h (doprnt): Remove.
11777 * Makefile.in (base_obj): Remove doprnt.o.
11778 * deps.mk (doprnt.o): Remove.
11780 error: Print 32- and 64-bit integers portably (Bug#8435).
11781 Without this change, on typical 64-bit hosts error ("...%d...", N)
11782 was used to print both 32- and 64-bit integers N, which relied on
11783 undefined behavior.
11784 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
11785 * lisp.h (error, verror): Mark as printf-like functions.
11786 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
11787 Report overflow in size calculations when allocating printf buffer.
11788 Do not truncate output string at its first null byte.
11789 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
11790 Truncate the output at a character boundary, since vsnprintf does not
11791 do that.
11792 * charset.c (check_iso_charset_parameter): Convert internal
11793 character to string before calling 'error', since %c now has the
11794 printf meaning.
11795 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
11796 overflow when computing char to be passed to 'error'. Do not
11797 pass Lisp_Object to 'error'; pass the integer instead.
11798 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
11799 formatted with plain %d.
11801 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
11803 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
11805 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
11807 * xterm.c (x_catch_errors): Remove duplicate declaration.
11809 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
11811 * xdisp.c, lisp.h (message_nolog): Remove; unused.
11813 2011-04-10 Jim Meyering <meyering@redhat.com>
11815 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
11816 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
11817 return ssize_t not "int", and use size_t as the buffer length.
11818 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
11819 * gnutls.h: Update declarations.
11820 * process.c (read_process_output): Use ssize_t, to match.
11821 (send_process): Likewise.
11823 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11825 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
11827 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11829 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
11830 Use unsigned char, to match FcChar8 type definition.
11832 * xterm.c (handle_one_xevent):
11833 * xmenu.c (create_and_show_popup_menu):
11834 * xselect.c (x_decline_selection_request)
11835 (x_reply_selection_request): Avoid type-punned deref of X events.
11837 2011-04-09 Eli Zaretskii <eliz@gnu.org>
11839 Fix some uses of `int' instead of EMACS_INT.
11840 * search.c (string_match_1, fast_string_match)
11841 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
11842 (scan_buffer, find_next_newline_no_quit)
11843 (find_before_next_newline, search_command, Freplace_match)
11844 (Fmatch_data): Make some `int' variables be EMACS_INT.
11846 * xdisp.c (display_count_lines): 3rd argument and return value now
11847 EMACS_INT. All callers changed.
11848 (pint2hrstr): Last argument is now EMACS_INT.
11850 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
11851 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
11852 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
11853 (decode_coding_utf_16, decode_coding_emacs_mule)
11854 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
11855 (decode_coding_ccl, decode_coding_charset)
11856 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
11857 (decode_coding_iso_2022, decode_coding_emacs_mule)
11858 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
11859 <char_offset, last_offset>: Declare EMACS_INT.
11860 (encode_coding_utf_8, encode_coding_utf_16)
11861 (encode_coding_emacs_mule, encode_invocation_designation)
11862 (encode_designation_at_bol, encode_coding_iso_2022)
11863 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
11864 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
11865 Declare EMACS_INT.
11866 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
11867 (encode_invocation_designation): Last argument P_NCHARS is now
11868 EMACS_INT.
11869 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
11870 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
11872 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
11873 All users changed.
11875 * ccl.c (Fccl_execute_on_string): Declare some variables
11876 EMACS_INT.
11878 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
11880 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
11882 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
11884 * process.c (Fformat_network_address): Doc fix.
11886 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
11888 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
11890 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
11892 * keyboard.c (read_char): Call Lisp function help-form-show,
11893 instead of using internal_with_output_to_temp_buffer.
11894 (Qhelp_form_show): New var.
11895 (syms_of_keyboard): Use DEFSYM macro.
11897 * print.c (internal_with_output_to_temp_buffer): Function deleted.
11899 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
11901 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
11903 * process.c (Flist_processes): Remove to Lisp.
11904 (list_processes_1): Delete.
11906 2011-04-06 Eli Zaretskii <eliz@gnu.org>
11908 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
11910 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
11912 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
11914 Fix more problems found by GCC 4.6.0's static checks.
11916 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
11918 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
11920 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
11922 * xdisp.c (vmessage): Mark as a printf-like function.
11924 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
11926 * sound.c (sound_warning): Don't crash if arg contains a printf format.
11928 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
11929 printf-like functions.
11930 (tiff_load): Add casts to remove these marks before passing them
11931 to system-supplied API.
11933 * eval.c (Fsignal): Remove excess argument to 'fatal'.
11935 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
11936 This avoids several warnings with gcc -Wstrict-overflow.
11937 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
11938 directly, rather than having caller test rule sign. This avoids
11939 some unnecessary tests.
11940 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
11941 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
11942 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
11944 * xfont.c (xfont_text_extents): Remove var that was set but not used.
11945 (xfont_open): Avoid unnecessary tests.
11947 * composite.c (composition_gstring_put_cache): Use unsigned integer.

11954 (COMPOSITION_DECODE_RULE): Use it.
11955 * composite.c (get_composition_id): Remove unused local vars,
11956 by using the new macro.
11958 * textprop.c (set_text_properties_1): Change while to do-while,
11959 since the condition is always true at first.
11961 * intervals.c (graft_intervals_into_buffer): Mark var as used.
11962 (interval_deletion_adjustment): Return unsigned value.
11963 All uses changed.

11981 * print.c (print_error_message): Avoid int overflow.
11983 * font.c (font_list_entities): Redo for clarity,
11984 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

11999 (wordify): Omit three unnecessary tests.
12001 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

12008 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12010 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12011 (Finsert_file_contents): Remove unnecessary code checking fd.

12014 Check for integer overflow on size calculations.
12016 * buffer.c (Fprevious_overlay_change): Remove var that is set
12017 but not used.
12019 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12020 Remove vars that are set but not used.
12021 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12022 (timer_check_2): Mark vars as initialized.
12024 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12026 * image.c (lookup_image): Remove var that is set but not used.
12027 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12029 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12030 that are set but not used.
12032 * xfns.c (make_invisible_cursor): Don't return garbage
12033 if XCreateBitmapFromData fails (Bug#8410).
12035 * xselect.c (x_get_local_selection, x_handle_property_notify):
12036 Remove vars that are set but not used.
12038 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12039 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12041 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12042 Remove var that is set but not used.
12043 (scroll_bar_windows_size): Now size_t, not int.
12044 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12045 Check for overflow.
12047 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12048 (map_tty_color) [!defined MSDOS]: Likewise.
12050 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12052 * coding.c: Remove vars that are set but not used.
12053 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12054 All callers changed.
12055 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12056 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12057 (decode_coding_charset): Remove vars that are set but not used.
12059 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12060 that is set but not used.
12062 * print.c (print_object): Remove var that is set but not used.
12064 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12065 The gnulib version avoids calling malloc in the usual case,
12066 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12067 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12068 * filelock.c (current_lock_owner): Likewise.
12069 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12070 * sysdep.c: Include allocator.h, careadlinkat.h.
12071 (emacs_no_realloc_allocator): New static constant.
12072 (emacs_readlink): New function.
12073 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12074 ../lib/careadlinkat.h.
12076 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12078 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12079 first non-nil return value).
12081 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
12083 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6

12095 (get_per_char_metric): Remove parameter `f', unused since
12096 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

12101 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12102 (ns_get_family): Likewise.
12104 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12106 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12108 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12110 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12111 later (Bug#8403).
12113 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12115 Add lexical binding.
12117 * window.c (Ftemp_output_buffer_show): New fun.
12118 (Fsave_window_excursion):
12119 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
12121 * lread.c (lisp_file_lexically_bound_p): New function.
12122 (Fload): Bind Qlexical_binding.
12123 (readevalloop): Remove `evalfun' arg.
12124 Bind Qinternal_interpreter_environment.
12125 (Feval_buffer): Bind Qlexical_binding.
12126 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12127 Mark as dynamic.
12128 (syms_of_lread): Declare `lexical-binding'.
12130 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12132 * keyboard.c (eval_dyn): New fun.
12133 (menu_item_eval_property): Use it.
12135 * image.c (parse_image_spec): Use Ffunctionp.
12137 * fns.c (concat, mapcar1): Accept byte-code-functions.
12139 * eval.c (Fsetq): Handle lexical vars.
12140 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12141 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12142 (FletX, Flet): Obey lexical binding.
12143 (Fcommandp): Handle closures.
12144 (Feval): New `lexical' arg.
12145 (eval_sub): New function extracted from Feval. Use it almost
12146 everywhere where Feval was used. Look up vars in lexical env.
12147 Handle closures.
12148 (Ffunctionp): Move from subr.el.
12149 (Ffuncall): Handle closures.
12150 (apply_lambda): Remove `eval_flags'.
12151 (funcall_lambda): Handle closures and new byte-code-functions.
12152 (Fspecial_variable_p): New function.
12153 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12154 but without exporting it to Lisp.
12156 * doc.c (Fdocumentation, store_function_docstring):
12157 * data.c (Finteractive_form): Handle closures.
12159 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12160 interactive spec.
12162 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12163 New byte-codes.
12164 (exec_byte_code): New function extracted from Fbyte_code to handle new
12165 calling convention for byte-code-functions. Add new byte-codes.
12167 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
12169 * alloc.c (Fmake_symbol): Init new `declared_special' field.
12171 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12173 * xdisp.c (redisplay_internal): Fix prototype.
12175 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12177 * xdisp.c (SCROLL_LIMIT): New macro.
12178 (try_scrolling): Use it when setting scroll_limit.
12179 Limit scrolling to 100 screen lines.
12180 (redisplay_window): Even when falling back on "recentering",
12181 position point in the window according to scroll-conservatively,
12182 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12184 (try_scrolling): When point is above the window, allow searching
12185 as far as scroll_max, or one screenful, to compute vertical
12186 distance from PT to the scroll margin position. This prevents
12187 try_scrolling from unnecessarily failing when
12188 scroll-conservatively is set to a value slightly larger than the
12189 window height. Clean up the case of PT below the margin at bottom
12190 of window: scroll_max can no longer be INT_MAX. When aggressive
12191 scrolling is in use, don't let point enter the opposite scroll
12192 margin as result of the scroll.
12193 (syms_of_xdisp) <scroll-conservatively>: Document the
12194 threshold of 100 lines for never-recentering scrolling.
12196 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12198 * dispextern.h (move_it_by_lines):
12199 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
12200 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
12201 (message_log_check_duplicate): Remove parameters `prev_bol' and
12202 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12203 (redisplay_internal): Remove parameter `preserve_echo_area',
12204 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12206 * indent.c (Fvertical_motion):
12207 * window.c (window_scroll_pixel_based, Frecenter):
12208 Don't pass `need_y_p' to `move_it_by_lines'.
12210 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12212 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12213 steal a few bits to be more compact.

12215 Remove unneeded casts.
12217 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12219 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12221 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12222 binding" message (bug#7967).
12224 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12226 Fix more problems found by GCC 4.6.0's static checks.
12228 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12229 Remove unused local var.
12231 * editfns.c (Fmessage_box): Remove unused local var.
12233 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12234 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12235 Omit unused local vars.
12236 * window.c (shrink_windows): Omit unused local var.
12237 * menu.c (digest_single_submenu): Omit unused local var.
12238 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12239 Omit unused local var.
12241 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12242 Don't assume string length fits in int.
12243 (keyremap_step, read_key_sequence): Use size_t for sizes.

12247 instead of alloca (Bug#8344).
12249 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12250 (Fbacktrace_frame): Don't assume nframes fits in int.
12252 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
12254 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
12255 concerns.
12257 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12259 * cm.c (calccost): Turn while-do into do-while, for clarity.
12261 * keyboard.c (syms_of_keyboard): Use the same style as later
12262 in this function when indexing through an array. This also
12263 works around GCC bug 48267.
12265 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12267 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12269 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12270 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12272 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12273 This avoids undefined behavior on integer overflow, and is a bit
12274 more convenient anyway since it is compared to a size_t variable.
12276 Variadic C functions now count arguments with size_t, not int.
12277 This avoids an unnecessary limitation on 64-bit machines, which
12278 caused (substring ...) to crash on large vectors (Bug#8344).

12288 * fns.c (concat): Likewise.
12289 * frame.c (x_set_frame_parameters): Likewise.
12290 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12291 0 if not found, not -1. All callers changed.
12293 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12294 (stack_copy_size): Now size_t, not int.
12295 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12297 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12299 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
12300 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

12316 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12317 don't set the hook to nil, but remove the offending function instead.
12318 (Qcommand_hook_internal): Remove, unused.
12319 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12320 Vcommand_hook_internal.

12323 (funcall_nil, funcall_not): New functions.
12324 (run_hook_with_args): Call each function through a `funcall' argument.

12338 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
12339 All callers changed.
12341 * w32.c (_wsa_errlist): Use braces for struct initializers.
12343 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

12488 2011-03-23 Julien Danjou <julien@danjou.info>
12490 * term.c (Fsuspend_tty, Fresume_tty):
12491 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
12492 * window.c (temp_output_buffer_show):
12493 * insdel.c (signal_before_change):
12494 * frame.c (Fhandle_switch_frame):
12495 * fileio.c (Fdo_auto_save):

12500 * buffer.c (Fkill_all_local_variables):
12501 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12502 Use Frun_hooks.
12503 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
12504 unconditionally since it does the check itself.
12506 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12508 Fix more problems found by GCC 4.5.2's static checks.
12510 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12511 the first time through the loop, since we know p0 < p1 then.
12512 This also avoids a gcc -Wstrict-overflow warning.
12514 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12515 leading to a memory leak, possible in functions like
12516 load_charset_map_from_file that can allocate an unbounded number
12517 of objects (Bug#8318).
12519 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12520 that could (at least in theory) be that large.
12522 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12523 This is less likely to overflow, and avoids undefined behavior if
12524 overflow does occur. All callers changed. Use strtoul to scan
12525 for the unsigned long integer.
12526 (pint2hrstr): Simplify and tune code slightly.
12527 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

12540 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12542 * process.c (Fmake_network_process): Use socklen_t, not int,
12543 where POSIX says socklen_t is required in portable programs.
12544 This fixes a porting bug on hosts like 64-bit HP-UX, where
12545 socklen_t is wider than int (Bug#8277).
12546 (Fmake_network_process, server_accept_connection):
12547 (wait_reading_process_output, read_process_output):
12548 Likewise.

12560 Make tparam.h and terminfo.c consistent.
12561 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12562 Include tparam.h instead, since it declares them.
12563 * cm.h (PC): Remove extern decl; tparam.h now does this.
12564 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12565 * terminfo.c: Include tparam.h, to check interfaces.
12566 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12567 (tparam): Adjust signature to match interface in tparam.h;
12568 this removes some undefined behavior. Check that outstring and len
12569 are zero, which they always are with Emacs.
12570 * tparam.h (PC, BC, UP): New extern decls.
12572 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12573 (xftfont_open): Rename locals to avoid shadowing.

12587 * composite.c (composition_compute_stop_pos): Rename local to
12588 avoid shadowing.
12589 (composition_reseat_it): Remove unused locals.
12590 (find_automatic_composition, composition_adjust_point): Likewise.
12591 (composition_update_it): Mark var as initialized.

12599 (BUF_DEC_POS): Be more systematic about renaming local temporaries
12600 to avoid shadowing.

12612 Fix pointer signedness.
12613 (alsa_choose_format): Remove unused local var.
12614 (wav_play): Initialize a variable to 0, to prevent undefined
12615 behavior (Bug#8278).
12617 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
12619 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
12621 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
12622 clobbering (Bug#8298).
12623 * sysdep.c (sys_subshell): Likewise.
12624 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12626 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
12627 This should get cleaned up, so that child_setup has the
12628 same signature on all platforms.
12630 * callproc.c (call_process_cleanup): Now static.
12631 (relocate_fd): Rename locals to avoid shadowing.
12633 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
12635 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
12636 not to be necessary, and produces flickering.
12638 2011-03-20 Glenn Morris <rgm@gnu.org>
12640 * config.in: Remove file.
12642 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

12687 Define only if needed.
12689 * unexelf.c (unexec): Name an expression,
12690 to avoid gcc -Wbad-function-cast warning.
12691 Use a different way to cause a compilation error if anyone uses
12692 n rather than nn, a way that does not involve shadowing.
12693 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
12695 * deps.mk (unexalpha.o): Remove; unused.
12697 New file unexec.h, the (simple) interface for unexec (Bug#8267).

12786 they're used.
12787 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

12819 (WORDCHAR_P): Likewise. This one is never needed, but is used

12851 gcpro1, gcpro2, etc.
12852 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
12853 of the new macros.
12854 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
12855 argument, for consistency with GCPRO2_VAR, etc: it is now the
12856 prefix of the variable, not the variable itself. All uses
12857 changed.

12859 Rename locals to avoid shadowing.
12861 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
12862 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
12863 dired.c's scmp function, had undefined behavior.
12864 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12865 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
12866 * buffer.h: ... to here, because these macros use current_buffer,
12867 and the new implementation with inline functions needs to have
12868 current_buffer in scope now, rather than later when the macros
12869 are used.
12870 (downcase, upcase1): New static inline functions.
12871 (DOWNCASE, UPCASE1): Reimplement using these functions.
12872 This avoids undefined behavior in expressions like

12874 from race conditions in accessing the global variables
12875 case_temp1 and case_temp2.
12876 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
12877 * lisp.h (case_temp1, case_temp2): Remove their decls.

12886 Now static.
12887 (file_name_as_directory): Use const pointers when appropriate.
12888 (Fexpand_file_name): Likewise. In particular, newdir might
12889 point at constant storage, so make it a const pointer.

12891 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
12892 signedness issues.

12898 to avoid shadowing.
12900 * marker.c (bytepos_to_charpos): Remove; unused.
12902 * lisp.h (verify_bytepos, count_markers): New decls,
12903 so that gcc does not warn that these functions aren't declared.
12905 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
12906 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
12907 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
12908 (copy_text): Remove unused local var.

12911 (lock_file_1): Rename local to avoid shadowing.
12913 * buffer.c (fix_overlays_before): Mark locals as initialized.
12914 (fix_start_end_in_overlays): Likewise. This function should be
12915 simplified by using pointers-to-pointers, but that's a different
12916 matter.
12917 (switch_to_buffer_1): Now static.
12918 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
12919 (report_overlay_modification): Rename locals to avoid shadowing.

12922 Fix pointer signedness issue.
12923 (sys_subshell): Mark local as volatile if checking for lint,
12924 to suppress a gcc -Wclobbered warning that does not seem to be right.
12925 (MAXPATHLEN): Define only if needed.
12927 * process.c (serial_open, serial_configure): Move decls from here ...
12928 * systty.h: ... to here, so that they can be checked.
12930 * fns.c (get_random, seed_random): Move extern decls from here ...
12931 * lisp.h: ... to here, so that they can be checked.
12933 * sysdep.c (reset_io): Now static.
12934 (wait_for_termination_signal): Remove; unused.
12936 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
12937 (copy_keymap_item, append_key, push_text_char_description):
12938 Now static.
12939 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
12940 (DENSE_TABLE_SIZE): Remove; unused.
12941 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
12942 (describe_map_tree):
12943 Rename locals to avoid shadowing.
12945 * keyboard.c: Declare functions static if they are not used elsewhere.

12962 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
12963 (DEFINE_DUMMY_FUNCTION): New macro.
12964 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
12965 Use it.
12966 (main): Add casts to avoid warnings
12967 if GCC considers string literals to be constants.
12969 * lisp.h (fatal_error_signal): Add decl, since it's exported.
12971 * dbusbind.c: Pointer signedness fixes.
12972 (xd_signature, xd_append_arg, xd_initialize):
12973 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12974 (Fdbus_method_return_internal, Fdbus_method_error_internal):

13287 -Wuninitialized does not deduce are never used uninitialized.
13288 (detect_coding_iso_2022): Initialize a local variable that might
13289 be used uninitialized. Leave a FIXME because it's not clear that
13290 this initialization is needed. (Bug#8211)
