3 * process.c (wait_reading_process_output): 'waitchannels' was unset
4 when read_kbd || !NILP (wait_for_cell); fix this.
6 Add GCC-style 'const' attribute to functions that can use it.
7 * character.h (char_resolve_modifier_mask):
8 * keyboard.h (make_ctrl_char):
9 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10 (init_character_once, next_almost_prime, init_fns, init_image)
11 (flush_pending_output, init_sound):
12 * mem-limits.h (start_of_data):
13 * menu.h (finish_menu_items):
14 Add ATTRIBUTE_CONST.
15 * emacs.c (DEFINE_DUMMY_FUNCTION):
16 Declare the dummy function with ATTRIBUTE_CONST.

18 Add decls with ATTRIBUTE_CONST.
20 Minor improvements to make_formatted_string.
21 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
22 where int is good enough, as vsprintf returns an int.
23 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
25 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
27 Use make_formatted_string to avoid double length calculation.

52 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
54 Move marker debugging code under MARKER_DEBUG.
55 * marker.c (MARKER_DEBUG): Move marker debugging code under
56 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
57 for bootstrap with --enable-checking (~3x slowdown reported
58 by Juanma Barranquero <lekktu@gmail.com>).
59 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
61 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
63 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
64 See <http://bugs.gnu.org/11825#29>.
66 2012-07-08 Eli Zaretskii <eliz@gnu.org>
68 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
69 has no font, use the frame's font. (Bug#11813)

71 on GUI frames.
72 (produce_special_glyphs): Move here from term.c.
74 * term.c (produce_special_glyphs): Move to xdisp.c.
76 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
77 section.
79 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>

82 of FRAME_FONT.
84 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
86 * lisp.h: Remove empty conditional.
88 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
90 * lread.c (load_path_check): Now static.
92 Fix some minor --with-ns problems found by static checking.
93 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
94 (x_set_font) [!HAVE_X_WINDOWS]:
95 * image.c (xpm_load_image) [HAVE_NS]:
96 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
97 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
98 Remove unused local.
99 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
100 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.

109 2012-07-07 Glenn Morris <rgm@gnu.org>
111 * lread.c (load_path_check): New function, split from init_lread.
112 (init_lread): Reorganize. Motivation:
113 If EMACSLOADPATH is set, check/warn about that rather than the
114 defaults, which we are not going to use. Hence we can remove
115 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
116 Don't warn if site-lisp directories are missing.
117 If not installed, start from a blank load-path, since
118 PATH_LOADSEARCH refers to the eventual installation directories.
120 2012-07-07 Eli Zaretskii <eliz@gnu.org>
122 Support truncation and continuation glyphs on GUI frames, when
123 fringes are disabled. (Bug#11832)
124 * xdisp.c (init_iterator): Get dimensions of truncation and
125 continuation glyphs even if on GUI frames. Adjust
126 it->last_visible_x on GUI frames when the left or right fringes,
127 or both, are absent.
128 (start_display, move_it_in_display_line_to): Handle the case of a
129 GUI frame without a fringe to display continuation or truncation
130 glyphs.
131 (insert_left_trunc_glyphs): Support GUI frames: make sure
132 truncation glyphs overwrite enough glyphs from the current line to
133 have sufficient space in pixels.
134 (display_line): Support truncation and continuation glyphs on GUI
135 frames. If some spare pixels are left on the line after inserting
136 the truncation glyphs, fill that space with a stretch glyph of a
137 suitably computed width.
139 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
140 produce_glyphs, to support GUI sessions.
142 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
144 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
146 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
148 Do not require float-time's arg to fit in time_t (Bug#11825).
149 This works better on hosts where time_t is unsigned, and where
150 float-time is applied to the (negative) difference between two times.
151 * editfns.c (decode_time_components): Last arg is now double *,
152 not int *, and means to store all the result as a double, without
153 worrying about whether the seconds part fits in time_t.
154 All callers changed.
155 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
156 All callers changed.
157 (Ffloat_time): Do not fail merely because the specified time falls
158 outside of time_t range.
160 2012-07-07 Glenn Morris <rgm@gnu.org>

169 Update dependencies.
171 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
173 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
175 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
176 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
177 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
178 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
179 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
180 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
182 * xfont.c (compare_font_names): Redo to omit the need for casts.
184 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
186 * xfns.c (Fx_change_window_property): Doc fix.
187 * w32fns.c (Fx_change_window_property): Doc fix.
189 * w32fns.c (Fx_window_property): Accept the same arguments as the
190 X Windows version. Doc fix.
191 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
193 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
194 Eli Zaretskii <eliz@gnu.org>
196 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
197 Windows-specific code from nt/config.nt moved here.
198 Obsolete settings removed.
200 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
202 * process.c: Avoid unnecessary calls to gettime.
203 (wait_reading_process_output): Don't get the time of day
204 when gobbling data immediately and not waiting, as there's no need
205 for it in that case. This removes a FIXME.
207 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
209 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
210 is defined (Bug#11768).
212 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
214 Fix marker debugging code.
215 * marker.c (byte_char_debug_check): Do not perform the check
216 if buffer is not multibyte.
217 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
218 Call byte_char_debug_check with correct arguments.
220 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
222 Compile marker debugging code only if ENABLE_CHECKING is defined.
223 * marker.c (byte_char_debug_check, count_markers):
224 Use only if ENABLE_CHECKING is defined.
225 (byte_debug_flag): Remove.
226 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
227 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
229 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
231 Avoid code repetition in marker-related functions.
232 * marker.c (attach_marker): New function.
233 (Fset_marker, set_marker_restricted, set_marker_both)
234 (set_marker_restricted_both): Use it.
235 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
236 Consistently rename charno to charpos.
237 (marker_position): Add eassert.
238 (marker_byte_position): Convert to eassert.

257 * window.c (save_window_save): Likewise.
259 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
261 Do not use Fdelete_overlay in delete_all_overlays
262 to avoid redundant calls to unchain_overlay.
263 * buffer.c (drop_overlay): New function.
264 (delete_all_overlays, Fdelete_overlay): Use it.
265 * minibuf.c (get_minibuffer): Fix comment.
267 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
269 Port to OpenBSD 5.1 amd64.
270 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
271 This is needed for OpenBSD, and should be harmless on all BSD systems.
272 Also, include <sys/sysctl.h>, as it should be available on all
273 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
274 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
275 use p_pid member, not kp_proc.pid.
277 2012-07-06 Glenn Morris <rgm@gnu.org>
279 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
281 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
283 More xmalloc and related cleanup.
284 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
285 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
286 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
287 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
288 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
289 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:

292 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
293 * xterm.c:
294 Omit needless casts involving void * pointers and allocation.
295 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
296 as the former is more robust if P's type is changed.
297 Prefer xzalloc to xmalloc + memset 0.
298 Simplify malloc-or-realloc to realloc.
299 Don't worry about xmalloc returning a null pointer.
300 Prefer xstrdup to xmalloc + strcpy.
301 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
302 growing it.
303 * keyboard.c (apply_modifiers_uncached): Prefer local array to
304 alloca of a constant.
306 2012-07-05 Eli Zaretskii <eliz@gnu.org>
308 * xdisp.c (display_line): Fix horizontal pixel coordinates when
309 hscroll is larger than the line width. Fixes long and futile
310 looping inside extend_face_to_end_of_line (on a TTY) producing
311 glyphs that are not needed and thrown away.
313 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
315 * marker.c (set_marker_restricted_both): Simplify by using
316 clip_to_bounds.
318 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
320 * editfns.c (region_limit): Simplify by using clip_to_bounds.
322 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
324 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is

334 (is_box_type): New function (Bug#11768).
335 (xg_tool_item_stale_p): Call is_box_type.
336 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
337 with default display (Bug#11768).
339 2012-07-05 Eli Zaretskii <eliz@gnu.org>
341 * xdisp.c (window_hscroll_limited): New function.
342 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
343 coordinates when window's hscroll is set to insanely large
344 values. (Bug#11857)
346 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
348 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

410 Problem reported by Troels Nielsen in
411 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
413 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
415 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
416 This should be fixed in a better way; see Eli Zaretskii in
417 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
418 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
420 * fileio.c (time_error_value): Rename from special_mtime.
421 The old name's problems were noted by Eli Zaretskii in
422 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
424 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
425 This variable's comment says Emacs needs at least one GDB-visible
426 symbol of type enum pvec_type, to work around GDB problems.
427 The symbol's value doesn't matter.
429 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
430 that causes compilation to fail on pre-C99 compilers.
432 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

457 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
458 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
459 (sweep_vectors): Use it. Use local var `total_bytes' instead of
460 abusing vector->header.next.nbytes.
461 (live_vector_p): Use PVEC_TYPE.
462 (mark_object): Adapt code to extract pvectype. Use switch.
464 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
466 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
467 Tighten new eassert a bit.
469 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
471 Fix compilation with --enable-gcc-warnings and -O1
472 optimization level.
473 * doprnt.c (doprnt): Change type of tem to int, initialize
474 to avoid compiler warning. Add eassert.
475 * search.c (simple_search): Initialize match_byte to avoid
476 compiler warning. Add eassert.
478 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
480 Avoid weird behavior with large horizontal scrolls.
481 Without this change, for example, large hscroll values would
482 mess up Emacs's display on Fedora 15 x86, presumably due to
483 overflows in int calculations in the display code.
484 Also, if buffers had long lines, Emacs would freeze.
485 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
486 (set_window_hscroll): New function, containing the old guts of
487 Fset_window_hscroll. Return the clipped value.
488 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
489 This avoids the need to check against PTRDIFF_MAX.
491 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
493 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
495 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
497 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
499 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
500 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
501 since GCC 4.4.6 issues a bogus warning for them.
503 Fix bugs in file timestamp newness comparisons.
504 * fileio.c (Ffile_newer_than_file_p):
505 * lread.c (Fload): Use full timestamp resolution of files,
506 not just the 1-second resolution, so that files that are only
507 slightly newer still count as newer.
508 * fileio.c (Ffile_newer_than_file_p): Don't assume file
509 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
511 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
513 * fileio.c: Improve handling of file time marker. (Bug#11852)
514 (special_mtime): New function.
515 (Finsert_file_contents, Fverify_visited_file_modtime):
516 Use it to set special mtime values consistently.
518 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
520 * fileio.c (Finsert_file_contents): Properly handle st_mtime
521 marker for non-existing file. (Bug#11852)
523 2012-07-03 Glenn Morris <rgm@gnu.org>
525 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
526 and did not make it into globals.h).
528 2012-07-03 Tom Tromey <tromey@redhat.com>
530 * window.c (Fset_window_margins, Fset_window_fringes)

547 static.
548 * dired.c (Ffile_attributes): No longer static.
549 * composite.c (Fcomposition_get_gstring): No longer static.
550 * callproc.c (Fgetenv_internal): No longer static.
552 * ccl.h: Remove EXFUNs.
553 * buffer.h: Remove EXFUNs.
554 * dispextern.h: Remove EXFUNs.
555 * intervals.h: Remove EXFUNs.
556 * fontset.h: Remove EXFUN.
557 * font.h: Remove EXFUNs.
558 * dosfns.c (system_process_attributes): Remove EXFUN.

560 * lisp.h: Remove EXFUNs.
561 * w32term.h: Remove EXFUNs.
562 * window.h: Remove EXFUNs.
563 * xsettings.h: Remove EXFUN.
564 * xterm.h: Remove EXFUN.
566 2012-07-03 Glenn Morris <rgm@gnu.org>
568 * lisp.h (Frandom): Make it visible to C.
569 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
570 buffer for invisible buffers. (Bug#1229)
572 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
574 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
575 values which aren't power of 2.
576 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
577 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
578 accordingly.
580 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
582 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
584 * alloc.c (mark_object): Revert part of last patch to use `switch'.
586 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
588 * alloc.c (allocate_vector_block): Remove redundant
589 calls to mallopt if DOUG_LEA_MALLOC is defined.
590 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
591 avoid calls to mallopt if zero_vector is returned.
593 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
595 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
596 is enabled, avoid dereferencing NULL current_sblock if
597 running undumped.
599 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
601 Cleanup basic buffer management.
602 * buffer.h (struct buffer): Change layout to use generic vector
603 marking code. Fix some comments. Change type of 'clip_changed'
604 to bitfield. Remove unused #ifndef old.
605 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
606 (GET_OVERLAYS_AT): Fix indentation.
607 (for_each_per_buffer_object_at): New macro.
608 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
609 (Fbuffer_local_variables): Use it.
610 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
611 * alloc.c (allocate_buffer): Adjust to match new layout of
612 struct buffer. Fix comment.
613 (mark_overlay): New function.
614 (mark_buffer): Use it. Use mark_vectorlike to mark normal
615 Lisp area of struct buffer.
616 (mark_object): Use it. Adjust marking of misc objects
617 and related comments.
619 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
621 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
622 wrapper that is not needed because the wrapped code is a no-op (zero
623 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
624 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
626 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
628 * alloc.c (mark_buffer): Simplify. Remove prototype.
629 (mark_object): Add comment. Reorganize marking of vector-like
630 objects. Use CHECK_LIVE for all vector-like objects except buffers
631 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
632 redundant calls to mark_vectorlike for bool vectors.
634 2012-06-30 Glenn Morris <rgm@gnu.org>
636 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
638 * epaths.in (PATH_SITELOADSEARCH): New.
639 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
640 This is rather than relying on --enable-locallisppath elements
641 having "site-lisp" in their names. (Bug#10208#25, 11658)
643 2012-06-30 Eli Zaretskii <eliz@gnu.org>
645 * w32proc.c (sys_select): Accept and ignore one more argument.
647 * w32.c (emacs_gnutls_pull): Call select with one more argument.
649 * sysselect.h [DOS_NT]: Don't include sys/select.h.
650 (pselect) [!MS_DOS]: Redirect to sys_select.
652 * sysdep.c: Don't include dos.h and dosfns.h.
654 * process.c (sys_select):
655 * msdos.c (sys_select): Accept one more argument and ignore it.
657 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
658 adapt data types and code to that.
660 * dosfns.c:
661 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
662 which clashes with the gnulib function of the same name.
664 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
666 * font.c (font_style_to_value, font_style_symbolic)
667 (font_prop_validate_style): Add type checks for values in
668 font_style_table.
670 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
671 argument.
672 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
673 uses.
675 2012-06-29 Eli Zaretskii <eliz@gnu.org>
677 * xdisp.c (try_window_id): Undo last change.
679 * w32.c (getwd): Adjust commentary about startup_dir.
680 (init_environment): Always call sys_access, even in non-MSVC
681 builds. Don't chdir to the directory of the Emacs executable.
682 This undoes code from 1997 which was justified by the need to
683 "avoid conflicts when removing and renaming directories". But its
684 downside was that every relative file name was being interpreted
685 relative to the directory of the Emacs executable, which can never
686 be TRT. In particular, it broke sys_access when called with
687 relative file names.
688 (sys_access): Map GetLastError to errno.
690 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
692 * window.h (struct window): Change type of 'fringes_outside_margins'
693 to bitfield. Fix comment. Adjust users accordingly.

695 Adjust comment.
696 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
697 to ptrdiff_t.
699 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

702 Add QUIT to make the loop interruptible.
704 2012-06-29 Glenn Morris <rgm@gnu.org>
706 * charset.c (init_charset): Make lack of etc/charsets fatal.
708 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
710 * editfns.c (region_limit): Fix type mismatch.
712 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
714 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
715 undefined. Convert from xassert to eassert.
716 * nsmenu.m: Convert from xassert to eassert.
717 * nsterm.m: Likewise.
719 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

723 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
725 Avoid integer overflow on scroll-left and scroll-right.
726 * window.c (HSCROLL_MAX): New macro.
727 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
728 overflow when requested scroll falls outside ptrdiff_t range.
730 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
732 * window.h (struct window): Change type of 'hscroll',
733 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
734 'last_modified' and 'last_overlay_modified' to EMACS_INT.
735 Adjust users accordingly.
736 * xdisp.c (try_cursor_movement): Replace type check with eassert.
737 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
738 from EMACS_INT to ptrdiff_t.
739 (make_window): Omit redundant initialization.
741 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
743 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
745 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
747 * window.h (struct window): Change type of 'use_time' and
748 'sequence_number' from Lisp_Object to int.

809 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
810 avoid GCC warning about unused macro.
812 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
814 * alloc.c (allocate_string): Omit intervals initialization.
815 * alloc.c (make_uninit_multibyte_string): Initialize intervals
816 as in make_pure_string and make_pure_c_string.
818 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
820 * alloc.c (allocate_string): Fix last change.

855 * alloc.c (allocate_window): Zero out non-Lisp part of newly
856 allocated window.

874 a better opportunity to optimize away calls to strlen when the
875 function is called with compile-time constant argument.
876 * image.c (imagemagick_error): Convert to build_string.
877 * w32proc.c (sys_spawnve): Likewise.
878 * xterm.c (x_term_init): Likewise.
880 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
882 Use sprintf return value instead of invoking strlen on result.
883 In the old days this wasn't portable, since some sprintf
884 implementations returned char *. But they died out years ago and
885 Emacs already assumes sprintf returns int.
886 Similarly for float_to_string.
887 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
888 * ccl.c (ccl_driver):
889 * character.c (string_escape_byte8):

892 * print.c (print_object):
893 * xdisp.c (message_dolog):
894 * xfns.c (syms_of_xfns):
895 Use sprintf or float_to_string result to avoid need to call strlen.
896 * data.c (Fnumber_to_string):
897 Use make_unibyte_string, since the string must be ASCII.
898 * lisp.h, print.c (float_to_string): Now returns int length.
899 * term.c (produce_glyphless_glyph):
900 Use sprintf result rather than recomputing it.
902 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
903 * Makefile.in (ALL_CFLAGS):

910 strcasecmp if available.

928 * gtkutil.c (get_utf8_string): Remove redundant assignment.
929 sprintf already null-terminates its output.

933 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
935 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

938 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
940 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
941 instead of truncating it to 63 (admittedly a generous limit).
943 * process.c: Fix spelling and caps in comments.
945 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
947 * emacs.c (setpgrp): Remove definition, unused.

1037 language ID in the event parameters.
1039 * w32term.c (w32_read_socket): Put the new keyboard codepage into

1071 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1073 Support higher-resolution time stamps (Bug#9000).
1074 The time stamps are only nanosecond-resolution at the C level,
1075 since that's the best that any real-world system supports now.
1076 But they are picosecond-resolution at the Lisp level, as that's
1077 easy, and leaves room for future OS improvements.
1079 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1080 (LIBES): Use it.
1082 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1083 Don't get current time unless it's needed.
1085 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1086 now provides it if it's absent.
1087 (start_atimer): Port to higher-res time stamps.
1088 Check for time stamp overflow. Don't get current time more
1089 often than is needed.
1091 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1092 Include systime.h, not time.h.
1093 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1095 * dired.c: Include stat-time.h.
1096 (Ffile-attributes): File times now have higher resolution.
1098 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
1099 (struct image): Timestamp now has higher resolution.
1101 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1102 has at least microseconds now. All uses removed.
1103 (update_frame, update_single_window, update_window, update_frame_1)
1104 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1106 * editfns.c (time_overflow): Now extern.
1107 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1108 (float-time, Fformat_time_string, Fcurrent_time_string)
1109 (Fcurrent_time_zone): Accept and generate higher-resolution
1110 time stamps.
1111 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
1112 (decode_time_components, lisp_seconds_argument): New functions.
1113 (make_time): Now static.
1114 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1115 Report an error if the time is invalid, rather than having the caller
1116 do that.
1118 * fileio.c: Include <stat-time.h>
1119 (Fcopy_file): Copy higher-resolution time stamps.
1120 Prefer to set the time stamp via a file descriptor if that works.
1121 (Fset_file_times, Finsert_file_contents, Fwrite_region)
1122 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1123 (Fvisited_file_modtime, Fset_visited_file_modtime):
1124 Support higher-resolution time stamps.
1126 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1128 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1130 * image.c (prepare_image_for_display, clear_image_cache)
1131 (lookup_image): Port to higer-resolution time stamps.
1133 * keyboard.c (start_polling, bind_polling_period):
1134 Check for time stamp overflow.
1135 (read_char, kbd_buffer_get_event, timer_start_idle)
1136 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1137 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1138 Port to higher-resolution time stamps. Do not assume time_t is signed.
1139 (decode_timer): New function. Timers are now vectors of length 9,
1140 not 8, to accommodate the picosecond component.
1141 (timer_check_2): Use it.
1143 * nsterm.m (select_timeout, timeval_subtract): Remove.
1144 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1145 as they're a bit more accurate and handle overflow better.
1146 (ns_select): Change prototype to be compatible with pselect.
1147 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1148 * nsterm.h (ns_select): Adjust prototype.
1150 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1151 us-resolution time stamps.
1152 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1154 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1156 * lisp.h (time_overflow): New decl.
1157 (wait_reading_process_output): First arg is now intmax_t, not int,
1158 to accommodate larger waits.
1160 * process.h (struct Lisp_Process.read_output_delay):
1161 Now counts nanoseconds, not microseconds.
1162 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1163 EMACS_HAS_USECS.
1164 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1165 (wait_reading_process_output):
1166 Port to ns-resolution time stamps.
1167 (Faccept_process_output, wait_reading_process_output):
1168 Check for time stamp overflow. Do not assume time_t is signed.
1169 (select_wrapper): Remove; we now use pselect.
1170 (Fprocess_attributes): Now generates ns-resolution time stamps.
1172 * sysdep.c: Include utimens.h. Don't include utime.h
1173 or worry about struct utimbuf; gnulib does that for us now.
1174 (gettimeofday): Remove; gnulib provides a substitute.
1175 (make_timeval): New function.
1176 (set_file_times): Now sets ns-resolution time stamps.
1177 New arg FD; all uses changed.
1178 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1179 (system_process_attributes):
1180 Now returns ns-resolution time stamp. All uses changed.
1181 Check for time stamp overflow.
1183 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1184 provides a substitute now.
1186 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1187 since it guarantees struct timespec.
1188 (EMACS_TIME): Now struct timespec, so that we can support
1189 ns-resolution time stamps.
1190 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1191 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1192 (EMACS_USECS): Remove.
1193 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1194 so multiply the arg by 1000 before storing it.
1195 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1196 New macros.
1197 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
1198 Port to ns-resolution time stamps.
1199 (EMACS_TIME_NEG_P): Remove; replaced by....
1200 (EMACS_TIME_SIGN): New macro.

1202 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
1203 (set_file_times, make_time, lisp_time_argument): Adjust signature.
1204 (make_timeval, make_lisp_time, decode_time_components): New decls.
1205 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1206 that it mishandled time_t overflow. You can't compare by subtracting!
1207 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1208 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1210 * term.c: Include <sys/time.h>.
1211 (timeval_to_Time): New function, for proper overflow wraparound.
1212 (term_mouse_position, term_mouse_click): Use it.
1214 * undo.c (record_first_change): Support higher-resolution time stamps
1215 in the undo buffer.
1216 (Fprimitive_undo): Use them when restoring time stamps.
1218 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1219 (w32_get_internal_run_time):
1220 Port to higher-resolution Emacs time stamps.
1221 (ltime): Now accepts single 64-bit integer, as that's more convenient
1222 for callers.
1224 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1226 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1227 for compatibility with pselect. Support ns-resolution time stamps.
1229 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1231 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1232 Check for time stamp overflow, and support ns-resolution time stamps.
1234 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1235 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1236 (timeval_subtract): Remove; no longer needed.
1237 (XTflash, XTring_bell, x_wait_for_event):
1238 Port to ns-resolution time stamps. Don't assume time_t is signed.
1240 2012-06-22 Chong Yidong <cyd@gnu.org>
1242 * xdisp.c (x_consider_frame_title): Revert last change.
1244 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1246 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1247 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1248 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1249 staticidx goes up to 1597 out of 1600 = 0x640.)
1251 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1253 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1254 Otherwise, the umask might be mistakenly 0 while handling input signals.
1256 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
1258 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

1264 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
1265 access to `contents' member of Lisp_Vector objects with AREF and ASET
1266 where appropriate.
1268 2012-06-19 Chong Yidong <cyd@gnu.org>
1270 * frame.c (delete_frame): When selecting a frame on a different
1271 text terminal, do not alter the terminal's top-frame.
1273 * xdisp.c (format_mode_line_unwind_data): Record the target
1274 frame's selected window and its terminal's top-frame.
1275 (unwind_format_mode_line): Restore them.
1276 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
1277 Callers changed.
1278 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1279 since tty frames can be explicitly named.
1280 (prepare_menu_bars): Likewise.
1282 * term.c (Ftty_top_frame): New function.
1284 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1286 Port byte-code-meter to modern targets.
1287 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
1288 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
1289 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
1290 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
1291 (METER_1, METER_2): Simplify.
1293 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
1295 * data.c (Fdefalias): Return `symbol' (bug#11686).
1297 2012-06-18 Martin Rudalics <rudalics@gmx.at>
1299 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
1300 gets killed during executing of this function (Bug#11665).
1301 Try to always return Qt when the buffer has been actually killed.
1302 (Vkill_buffer_query_functions): In doc-string say that functions
1303 run by this hook should not change the current buffer.
1305 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1307 Fix recently-introduced process.c problems found by static checking.
1308 * process.c (write_queue_push, write_queue_pop, send_process):

1311 (send_process): Remove unused local.
1313 2012-06-17 Chong Yidong <cyd@gnu.org>
1315 * xdisp.c (redisplay_internal): No need to redisplay terminal
1316 frames that are not on top.

1325 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
1327 * lisp.h (eassert): Assume C89 or later.
1328 This removes the need for CHECK.
1329 (CHECK): Remove. Its comments about always evaluating its
1330 argument were confusing, as 'eassert' typically does not evaluate
1331 its argument.
1333 * coding.c (produce_chars): Use ptrdiff_t, not int.
1335 * xterm.c (x_draw_underwave): Check for integer overflow.
1336 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

1430 If all the glyphs of the glyph row came from strings, and we have no
1431 cursor positioning clues, put the cursor on the first glyph of the
1432 row.

1453 Assume USE_2_TAGS_FOR_INTS.
1454 (xreload): Adjust $tagmask width to match recent lisp.h change.
1456 Simplify lisp.h in minor ways that should not affect code.
1457 * lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
1458 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)

1460 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
1461 (INTTYPEBITS): New macro, for clarity.
1462 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
1463 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):
1464 Simplify now that USE_LSB_TAG is always defined.

1477 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
1479 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
1480 instead of union.
1481 (XLI, XIL): Define.
1482 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
1483 Use them.
1484 * emacs.c (gdb_use_struct): Rename from gdb_use_union.
1485 * .gdbinit: Check gdb_use_struct instead of gdb_use_union.

1488 * frame.c (delete_frame): Remove outdated comment.
1489 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
1490 USE_LISP_UNION_TYPE.
1491 (Fw32_unregister_hot_key): Likewise.
1492 (Fw32_toggle_lock_key): Likewise.
1493 * w32menu.c (add_menu_item): Likewise.

1505 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
1507 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
1509 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
1510 * alloc.c (make_number) [!defined make_number]:
1511 Remove, as lisp.h always defines this now.

1514 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
1515 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
1516 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
1517 -DUSE_LSB_TAG=0, to override the automatically-selected default.
1518 USE_LSB_TAG now is always defined to be either 0 or 1.
1519 All uses changed.
1520 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
1521 code works fine either way, and efficiency is not a concern here,
1522 as the union type is for debugging, not for production.
1523 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
1524 Use an inline function on all platforms when using the union type,
1525 since this is simpler and 'static inline' can be used portably
1526 within Emacs now.
1527 (LISP_INITIALLY_ZERO): New macro.
1528 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
1529 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

1597 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
1598 dbus_type_is_basic if available.
1599 (xd_extract_signed, xd_extract_unsigned): Rename from
1600 extract_signed and extract_unsigned, respectively. Adapt callers.
1602 2012-06-09 Chong Yidong <cyd@gnu.org>

1609 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
1611 * xdisp.c (vmessage): Treat frame message as multibyte.
1612 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
1613 would generate the diagnostic "Making \302\247 buffer-local while
1614 let-bound!".
1616 2012-06-08 Eli Zaretskii <eliz@gnu.org>
1618 * dispnew.c (showing_window_margins_p): Undo last change, which
1619 was done due to an inadvertent commit.

1631 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
1632 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
1634 2012-06-08 Eli Zaretskii <eliz@gnu.org>
1636 * alloc.c (allocate_vectorlike): Fix last change.
1638 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
1640 Block-based vector allocation of small vectors.
1641 * lisp.h (struct vectorlike_header): New field `nbytes',
1642 adjust comment accordingly.
1643 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
1644 to denote vector blocks. Adjust users (live_vector_p,
1645 mark_maybe_pointer, valid_lisp_object_p) accordingly.

1658 0 items. Allocate new vector from block if vector size is less than
1659 or equal to VBLOCK_BYTES_MAX.
1660 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
1661 (init_alloc_once): Add call to init_vectors.
1663 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
1665 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
1667 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
1669 * doprnt.c (doprnt): Truncate multibyte char correctly.
1670 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
1671 would mishandle a string argument "Xc" if X was a multibyte
1672 character of length 2: it would truncate after X's first byte
1673 rather than including all of X.
1675 2012-06-06 Chong Yidong <cyd@gnu.org>
1677 * buffer.c (word_wrap): Doc fix.
1679 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

1705 position is past the end of the mode line string.
1707 * buffer.c (buffer_local_value_1): New function, split from
1708 Fbuffer_local_value; can return Qunbound.
1709 (Fbuffer_local_value): Use it.

1724 * minibuf.c (Fassoc_string): Remove duplicate declaration.
1726 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
1727 Convert pctcpu and pctmem to Lisp float properly.
1728 Let the compiler fold better, as 100.0/0x8000 is exact.
1730 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
1732 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
1733 cons_block.
1735 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
1737 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
1739 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
1741 For a 'struct window', replace some Lisp_Object fields to
1742 bitfields where appropriate, remove unused fields.
1743 * window.h (struct window): Remove unused 'last_mark_x' and
1744 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
1745 change it's type from Lisp_Object to bitfield.
1746 Change type of 'force_start', 'optional_new_start',
1747 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
1748 fields from Lisp_Object to bitfield. Adjust users accordingly.
1750 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
1752 Pacify gcc -Wdouble-precision when using Xaw.
1753 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
1754 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
1755 Use 'float' consistently, rather than 'float' in most places
1756 and 'double' in a couple of places.
1758 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1760 * xdisp.c (handle_stop): Detect whether we have overlay strings
1761 loaded by testing it->current.overlay_string_index to be
1762 non-negative, instead of checking whether n_overlay_strings is
1763 positive. (Bug#11587)
1765 2012-05-31 Chong Yidong <cyd@gnu.org>
1767 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
1769 * doc.c (Fsubstitute_command_keys): Doc fix.
1771 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1773 * search.c (search_buffer): Remove calls to
1774 r_alloc_inhibit_buffer_relocation, as it is now called by
1775 maybe_unify_char, which was the cause of relocation of buffer text
1776 in bug#11519.
1778 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1780 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
1781 for the duration of call to load_charset, to avoid problems with
1782 callers of maybe_unify_char that access buffer text through C
1783 pointers.
1785 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
1786 decrement the inhibition flag, instead of just setting or
1787 resetting it.
1789 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
1791 Remove obsolete '#define static' cruft.
1792 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
1793 This #undef was "temporary" in 2000; it is no longer needed
1794 now that '#define static' has gone away.
1795 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
1796 (gray_bitmap_bits): Remove; no longer needed.
1797 All uses replaced with definiens.

1805 Define only on platforms that need it.
1806 * emacs.c: Include <sys/gmon.h> when profiling.
1807 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

1809 (safe_bcopy): Remove decl; no longer has that name.
1810 (main): Coalesce #if into single bit of code, for simplicity.
1811 Cast pointers to uintptr_t, since standard libraries want integers
1812 and not pointers.
1813 * lisp.h (__executable_start): New decl.
1815 2012-05-31 Glenn Morris <rgm@gnu.org>
1817 * image.c (Fimagemagick_types): Doc fix.

1836 * lread.c (read1): Tiny simplification.
1838 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
1840 Do not create empty overlays with the evaporate property (Bug#9642).
1841 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
1842 Bug#9642, but explicitly check that the buffer the overlay would
1843 be moved to is live and rearrange lines to make sure that errors
1844 will not put the overlay in an inconsistent state.
1845 (Fdelete_overlay): Cosmetics.
1847 2012-05-28 Eli Zaretskii <eliz@gnu.org>
1849 * w32term.c (my_bring_window_to_top): New function.
1850 (x_raise_frame): Use handle returned by DeferWindowPos, which
1851 could be different from the original one.
1852 Call my_bring_window_to_top instead of my_set_foreground_window.
1853 (Bug#11513)
1855 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
1856 by calling BringWindowToTop.

1861 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
1863 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
1864 This avoids undefined behavior that might cause the eassert
1865 to not catch an out-of-range value.
1867 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
1869 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

1884 Only r_alloc_inhibit_buffer_relocation needed to be added;
1885 the others were already declared.
1887 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
1888 before checking whether it's out of range. Put the check inside
1889 eassert. See
1890 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
1892 2012-05-27 Ken Brown <kbrown@cornell.edu>

1899 * lisp.h [REL_ALLOC]: Add prototypes for external functions
1900 defined on ralloc.c.
1902 * buffer.c [REL_ALLOC]: Remove prototypes of
1903 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
1904 they are now on lisp.h.
1906 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
1908 * search.c (search_buffer): Use it to inhibit relocation of buffer
1909 text while re_search_2 is doing its job, because re_search_2 is
1910 passed C pointers to buffer text. (Bug#11519)
1912 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
1913 Update value to 24.
1915 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
1916 state after an additional call to move_it_in_display_line_to, keep
1917 the values of it->max_ascent and it->max_descent found for the
1918 entire line.
1919 (pos_visible_p): Revert the comparison against bottom_y to what it
1920 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.

1923 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
1925 Fix coding-related core dumps with gcc -ftrapv.
1926 The code was computing A - B, where A and B are pointers, and B is
1927 random garbage. This can lead to core dumps on platforms that
1928 have special pointer registers, and it also leads to core dumps on
1929 x86-64 when compiled with gcc -ftrapv. The fix is to compute
1930 A - B only when B is initialized properly.
1931 * coding.c (coding_set_source, coding_set_destination): Return void.
1932 (coding_change_source, coding_change_destinations): New functions,
1933 with the old behaviors of coding_set_source and coding_set_destination.

1948 New functions.
1949 (initialize_w32_display): Initialize mouse-highlight data.
1951 * w32inevt.c: Include termchar.h and window.h.
1952 (do_mouse_event): Support mouse-autoselect-window. When the mouse
1953 moves, call note_mouse_highlight. If help_echo changed, call
1954 gen_help_event to produce help-echo message in the echo area.
1955 Call clear_mouse_face if mouse_face_hidden is set in the mouse
1956 highlight info.
1958 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
1960 * lread.c (read1): Simplify slightly to avoid an overflow warning
1961 with GCC 4.7.0 on x86-64.
1963 2012-05-26 Eli Zaretskii <eliz@gnu.org>
1965 * bidi.c (bidi_mirror_char): Revert last change: an int is
1966 definitely wide enough here.
1968 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
1970 Fix integer width and related bugs (Bug#9874).

1981 (allocate_pseudovector):
1982 Use int, not EMACS_INT, where int is wide enough.
1983 (inhibit_garbage_collection, Fgarbage_collect):
1984 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

2002 (Foverlay_recenter, last_overlay_modification_hooks_used)
2003 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2004 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2005 (validate_region): Omit unnecessary test for b <= e,
2006 since that's guaranteed by the previous test.
2007 (adjust_overlays_for_delete): Avoid pos + length overflow.
2008 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2009 (report_overlay_modification):
2010 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2011 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2012 Omit pointer cast, which isn't needed anyway, and doesn't work
2013 after the EMACS_INT -> ptrdiff_t change.
2014 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2015 * buffer.h: Adjust decls to match defn changes elsewhere.

2020 not int, to avoid needless 32-bit limit on 64-bit hosts.
2021 (exec_byte_code): Use tighter memory-full test, one that checks
2022 for alloca overflow. Don't compute the address of the object just
2023 before an array, as that's not portable. Use EMACS_INT, not
2024 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2025 * callint.c (Fcall_interactively):
2026 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2027 * callproc.c (call_process_kill, Fcall_process):

2038 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2039 (casify_object): Avoid integer overflow when overallocating buffer.
2040 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2041 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

2043 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2044 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2045 integers are now checked earlier. All uses replaced with XINT.
2046 (ccl_driver):
2047 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2048 For CCL_MapSingle, check that content and value are in int range.

2050 Check that Vcode_version_map_vector is a vector.
2051 (resolve_symbol_ccl_program): Check that vector header is in range.
2052 Always copy the vector, so that we can check its contents reliably
2053 now rather than having to recheck each instruction as it's being
2054 executed. Check that vector words fit in 'int'.
2055 (ccl_get_compiled_code, Fregister_ccl_program)
2056 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2057 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
2058 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
2059 contents are in range.
2060 (Fccl_execute_on_string): Check that status is in range.
2061 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2062 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2063 Accept and return EMACS_INT, not int, because callers can pass values
2064 out of 'int' range.

2070 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2071 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2072 avoid mishandling large integers.

2079 Don't assume fixnum fits in int.
2080 (load_charset_map_from_vector, Fmap_charset_chars):

2082 (Fdefine_charset_internal): Check ranges here, more carefully.
2083 Don't rely on undefined behavior with signed left shift overflow.
2084 Don't assume unsigned int fits into fixnum, or that fixnum fits
2085 into unsigned int. Don't require max_code to be a valid fixnum;
2086 that's not true for gb10830 4-byte on a 32-bit host. Allow
2087 invalid_code to be a cons, for the same reason. Require code_offset
2088 to be a character. Avoid int overflow if max_char is close
2089 to INT_MAX.
2090 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2091 this is intended anyway and avoids some undefined behavior.
2092 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2093 INDEX_TO_CODE_POINT, as that's what it expects.
2094 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2095 * charset.h (DECODE_CHAR): Return int, not unsigned;
2096 this is what was intended anyway, and it avoids undefined behavior.
2097 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2098 integer-overflow issues.
2099 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2100 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2101 where the argument is EMACS_INT, and this behavior is not intended.
2102 * chartab.c (Fmake_char_table, Fset_char_table_range)
2103 (uniprop_get_decoder, uniprop_get_encoder):
2104 Don't assume fixnum fits in int.
2105 * cmds.c (move_point): New function, that does the gist of
2106 Fforward_char and Fbackward_char, but does so while checking
2107 for integer overflow more accurately.
2108 (Fforward_char, Fbackward_char): Use it.
2109 (Fforward_line, Fend_of_line, internal_self_insert)
2110 (internal_self_insert):
2111 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2112 Fix a FIXME, by checking for integer overflow when calculating
2113 target_clm and actual_clm.

2148 Don't access memory outside of the args array.
2149 (Fdefine_coding_system_internal): Check for charset-id overflow.

2759 Don't assume EMACS_INT overflows nicely into int.
2760 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
2761 may come from Lisp.

2772 * lisp.mk (lisp): Update for more files being compiled now.
2774 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

2794 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
2796 Remove src/m/*.
2797 This directory predates autoconf and is no longer needed nowadays.
2798 Move its few remaining bits of functionality to where they're needed.
2799 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
2800 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
2801 * m/template.h: Remove.
2802 * Makefile.in (M_FILE): Remove. All uses removed.
2803 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):

2811 what used to be in config.h, but not useful in #if.
2812 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
2813 define them any more.
2814 (VAL_MAX): New macro.
2815 (VALMASK): Use it.
2816 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
2817 BITS_PER_EMACS_INT, in #if.
2818 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
2819 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
2820 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
2821 * s/ms-w32.h (DATA_START):
2822 Move here from removed file m/intel386.h.
2823 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
2824 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
2826 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
2828 Assume C89 or later.
2829 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

2880 (Fword_search_forward, Fword_search_backward_lax)
2881 (Fword_search_forward_lax): Move functions to isearch.el
2882 (bug#10145, bug#11381).
2884 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
2886 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).

2890 * lread.c (init_obarray): Declare Qt and Qnil as special.
2892 2012-05-14 Glenn Morris <rgm@gnu.org>
2894 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
2895 Put "libexec" before "bin", for the sake of init_callproc_1.
2897 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
2899 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
2901 * unexaix.c: Port to more-recent AIX compilers.
2902 (report_error, report_error_1, make_hdr, copy_sym)
2903 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
2904 Make arguments const char *, not char *, to avoid violations of C
2905 standard and to fix some AIX warnings reported by Gilles Pion.
2907 2012-05-14 Eli Zaretskii <eliz@gnu.org>
2909 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
2910 already have overlays loaded.
2911 (handle_single_display_spec): Before returning without displaying
2912 fringe bitmap, synchronize the bidi iterator with the main display
2913 iterator, by calling iterate_out_of_display_property.
2914 (iterate_out_of_display_property): Detect buffer iteration by
2915 testing that it->string is a Lisp string.
2916 (get_next_display_element): When the current object is exhausted,
2917 and there's something on it->stack, call set_iterator_to_next to
2918 proceed with what's on the stack, instead of returning zero.
2919 (set_iterator_to_next): If called at the end of a Lisp string,
2920 proceed to consider_string_end without incrementing string
2921 position. Don't increment display vector index past the end of
2922 the display vector. (Bug#11417)
2923 (pos_visible_p): Don't report a position visible when move_it_to
2924 stopped at the last line of window, which happens to be scanned
2925 backwards by the bidi iteration. (Bug#11464)
2927 2012-05-14 Eli Zaretskii <eliz@gnu.org>
2929 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
2930 and right-margin display specs even if the spec is invalid or we
2931 are on a TTY, and thus unable to display on the fringes.
2932 That's because the text with the property will not be displayed anyway,
2933 so we need to signal to the caller that this is a "replacing"
2934 display spec. This fixes display when the spec is invalid or we
2935 are on a TTY.
2937 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
2939 * unexaix.c (make_hdr): Fix typo in prototype.
2940 This bug broke the build on AIX. Problem reported by Gilles Pion.
2942 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
2944 * keyboard.c (kbd_buffer_get_event): Read special events also in

2951 2012-05-12 Eli Zaretskii <eliz@gnu.org>
2953 * lisp.mk (lisp): Add newcomment.elc.
2955 2012-05-12 Glenn Morris <rgm@gnu.org>
2957 * Makefile.in (MKDIR_P): New, set by configure.
2958 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
2960 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
2962 Remove unused function hourglass_started.
2963 * dispextern.h (hourglass_started):

2965 * xdisp.c (hourglass_started): Remove.
2967 2012-05-10 Juanma Barranquero <lekktu@gmail.com>

2970 Update dependencies.
2972 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
2974 * xgselect.c (xg_select): Put maxfds+1 into a var.
2975 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
2977 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
2979 2012-05-10 Dave Abrahams <dave@boostpro.com>
2981 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
2982 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
2984 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
2986 * dbusbind.c (xd_registered_buses): New internal Lisp object.
2987 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
2988 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
2989 Initialize xd_registered_buses.
2991 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
2993 Untag more efficiently if USE_LSB_TAG.
2994 This is based on a proposal by YAMAMOTO Mitsuharu in
2995 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
2996 For an admittedly artificial (nth 8000 longlist) benchmark on
2997 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
2998 Emacs's overall text size by 1%.
2999 * lisp.h (XUNTAG): New macro.
3000 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3001 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3002 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3003 * eval.c (Fautoload):
3004 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3005 * frame.h (XFRAME): Use XUNTAG.
3007 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3008 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3009 Remove unportable assumptions about print widths of types like
3010 dbus_uint32_t.
3011 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3012 intptr_t when converting between pointer and integer, to avoid GCC
3013 warnings about wrong width.
3015 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3017 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3018 stack for each reader_thread, instead of defaulting to 8MB
3019 determined by the linker. This avoids failures in creating
3020 subprocesses on Windows 7, see the discussion in this thread:
3021 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3023 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3025 Fix up display of the *Minibuf-0* buffer in the mini window.
3026 * keyboard.c (read_char): Don't clear the echo area if there's no
3027 message to clear.
3028 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3029 contents of *Minibuf-0*) if there's no message displayed in its stead.
3031 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3033 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3034 batch mode.
3036 2012-05-06 Chong Yidong <cyd@gnu.org>
3038 * lisp.mk (lisp): Update.
3040 2012-05-05 Jim Meyering <meyering@redhat.com>
3042 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3044 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3046 * data.c (PUT_ERROR): New macro.
3047 (syms_of_data): Use it. Add new error type `user-error'.
3048 * undo.c (user_error): New function.
3049 (Fprimitive_undo): Use it.
3050 * print.c (print_error_message): Adjust print style for `user-error'.
3051 * keyboard.c (user_error): New function.
3052 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3054 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3056 Do not limit current-time-string to years 1000..9999.
3057 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3058 (Fcurrent_time_string): Support any year that is supported by the
3059 underlying localtime representation. Don't use asctime, as it
3060 has undefined behavior for years outside the range -999..9999.
3062 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3064 Fix race conditions involving setenv, gmtime, localtime, asctime.
3065 Without this fix, interrupts could mess up code that uses these
3066 nonreentrant functions, since setting TZ invalidates existing
3067 tm_zone or tzname values, and since most of these functions return
3068 pointers to static storage.
3069 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3070 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3071 Grow the critical sections to include not just invoking
3072 localtime/gmtime, but also accessing these functions' results
3073 including their tm_zone values if any, and any related TZ setting.
3074 (format_time_string): Last arg is now struct tm *, not struct tm **,
3075 so that the struct tm is saved in the critical section.
3076 All callers changed. Simplify allocation of initial buffer, partly
3077 motivated by the fact that memory allocation needs to be outside
3078 the critical section.
3080 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3082 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3083 with RESET_INTERVAL.
3085 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3086 Remove duplicated buffer name initialization.
3088 2012-05-02 Jim Meyering <jim@meyering.net>
3090 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3092 * xfns.c (x_window): Use xstrdup (Bug#11375).
3094 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3096 * xdisp.c (pos_visible_p): If already at a newline from the
3097 display string before the 'while' loop, don't walk back the glyphs
3098 from it3.glyph_row. Solves assertion violation when the display
3099 string begins with a newline (egg.el). (Bug#11367)
3101 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3103 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3104 Move to simple.el.
3106 2012-05-01 Glenn Morris <rgm@gnu.org>
3108 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3109 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3110 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3111 All were removed before 23.1.
3113 * dispnew.c: Remove HAVE_LIBNCURSES test;
3114 it is always true on relevant platforms.
3116 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3117 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3119 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3121 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3123 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3124 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3125 Remove.
3127 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3129 Do not avoid creating empty evaporating overlays (Bug#9642).
3130 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3131 That is, do not delete an evaporating overlay if it becomes
3132 empty after its bounds are adjusted to fit within its buffer.
3133 This fix caused other problems, and I'm reverting it until we get
3134 to the bottom of them.
3136 2012-04-27 Chong Yidong <cyd@gnu.org>
3138 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3140 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3142 * xdisp.c (pos_visible_p): If the window start position is beyond
3143 ZV, start the display from buffer beginning. Prevents assertion
3144 violation in init_iterator when the minibuffer window is scrolled
3145 via the scroll bar.
3147 * window.c (window_scroll_pixel_based): Likewise.
3149 2012-04-27 Chong Yidong <cyd@gnu.org>
3151 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3153 2012-04-27 Glenn Morris <rgm@gnu.org>
3155 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3156 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3158 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3160 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3161 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3163 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3165 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3166 display element, check also the underlying string or buffer
3167 character. (Bug#11341)
3169 * w32menu.c: Include w32heap.h.
3170 (add_menu_item): If the call to AppendMenuW (via
3171 unicode_append_menu) fails, disable Unicode menus only if we are
3172 running on Windows 9X/Me.
3174 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3176 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3177 (xgetint): Add missing shift for LSB tags.
3179 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3181 * keyboard.c (read_char): Don't wipe echo area for select window
3182 events: These might get delayed via `mouse-autoselect-window'
3183 (Bug#11304).
3185 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3187 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3188 manipulation of :loaded-from data.
3190 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3192 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3193 now a cons (bug#11311).
3195 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3197 Do not create empty overlays with the evaporate property (Bug#9642).
3198 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3199 if it becomes empty after its bounds are adjusted to fit within
3200 its buffer. Without this fix, in a nonempty buffer (let ((o
3201 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3202 yields an empty overlay that has the evaporate property, which is
3203 not supposed to happen.
3205 Fix minor GTK3 problems found by static checking.
3206 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3207 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3208 (struct _EmacsFixedClass, emacs_fixed_get_type):

3215 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
3216 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
3217 (EMACS_FIXED_GET_CLASS): Remove; unused.
3218 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
3220 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
3221 Problem reported by Juanma Barranquero for Windows -Wunused-function.
3223 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3225 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
3226 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
3227 (__malloc_size_t, __malloc_ptrdiff_t):
3228 Remove. All uses removed, replaced by the definiens if needed,
3229 since we can assume C89 or better now.
3230 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
3231 (protect_malloc_state, align, get_contiguous_space)
3232 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

3238 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
3239 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
3240 Define using prototypes, not old style.
3241 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
3242 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
3243 (align): Don't assume that signed integer overflow wraps around.
3244 Omit unused local var.
3245 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
3246 (_free_internal_nolock, memalign, mallochook, reallochook):

3252 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
3254 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

3368 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3370 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

3418 Improve ralloc.c interface checking.
3419 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
3420 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
3421 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
3422 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
3423 [REL_ALLOC]: ... to here, to check interface.
3424 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:

3439 aligned_Lisp_Misc instead of union Lisp_Misc.
3440 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
3442 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
3444 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
3445 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
3446 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
3447 * s/netbsd.h, s/sol2-6.h:
3448 Remove definition of GC_MARK_STACK, since the default now works.
3449 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
3450 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
3451 no longer the default.
3452 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
3454 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3456 * lread.c (lisp_file_lexically_bound_p):
3457 Fix hang at ";-*-\n" (bug#11238).
3459 2012-04-14 Eli Zaretskii <eliz@gnu.org>
3461 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
3462 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
3464 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
3466 * nsterm.m (constrainFrameRect): Always constrain when there is only
3467 one screen (Bug#10962).
3469 2012-04-13 Ken Brown <kbrown@cornell.edu>
3471 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
3473 2012-04-13 Reuben Thomas <rrt@sc3d.org>
3475 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
3477 2012-04-11 Daniel Colascione <dancol@dancol.org>
3479 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3480 against is gone. It's better to use vfork now so that when Cygwin
3481 gains a new, working vfork, we use it automatically (bug#10398).
3483 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
3485 * window.c (save_window_save): Obey window-point-insertion-type.
3487 2012-04-11 Glenn Morris <rgm@gnu.org>
3489 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.
3491 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
3493 * alloc.c (lisp_align_malloc): Remove unneeded prototype.
3495 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
3497 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
3498 (force_quit_count): New var.
3499 (handle_interrupt): Use it.
3501 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
3503 * w32.c (w32_delayed_load): Record the full path of the library
3504 being loaded (bug#10424).
3506 2012-04-09 Glenn Morris <rgm@gnu.org>
3508 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
3509 not just in the obarray, before snarfing them. (Bug#11036)
3511 * Makefile.in ($(leimdir)/leim-list.el):
3512 Pass EMACS rather than BUILT_EMACS.
3514 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
3516 * process.c (make_process):
3517 * process.h: Add integer `gnutls_handshakes_tried' member to
3518 process struct.
3520 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
3521 Add convenience `GNUTLS_LOG2i' macro.
3523 * gnutls.c (gnutls_log_function2i): Convenience log function.
3524 (emacs_gnutls_read): Use new log functions,
3525 `gnutls_handshakes_tried' process member, and
3526 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
3527 attempts per process (connection).
3529 2012-04-09 Chong Yidong <cyd@gnu.org>
3531 * eval.c (Fuser_variable_p, user_variable_p_eh)
3532 (lisp_indirect_variable): Functions deleted.
3533 (Fdefvar): Caller changed.
3535 * callint.c (Finteractive, Fcall_interactively):
3536 * minibuf.c (Fread_variable): Callers changed.
3538 2012-04-09 Eli Zaretskii <eliz@gnu.org>
3540 * xdisp.c (set_cursor_from_row): If the display string appears in
3541 the buffer at position that is closer to point than the position
3542 after the display string, display the cursor on the first glyph of
3543 the display string. Fixes cursor display when a 'display' text
3544 property immediately follows invisible text. (Bug#11094)
3546 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
3548 composite.c: use 'double' consistently
3549 * composite.c (get_composition_id): Use 'double' consistently
3550 instead of converting 'float' to 'double' and vice versa; this is
3551 easier to understand and avoids a GCC warning.
3553 2012-04-09 Glenn Morris <rgm@gnu.org>
3555 * Makefile.in: Generate leim-list with bootstrap-emacs, in
3556 preparation for dumping it with emacs. (Bug#4789)
3557 (leimdir): New variable.
3558 ($(leimdir)/leim-list.el): New rule.
3559 (emacs$(EXEEXT)): Depend on leim-list.el.
3561 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
3562 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
3563 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
3565 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
3567 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
3568 proper alignment.
3570 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
3572 * xml.c (init_libxml2_functions) [WINDOWSNT]:
3573 Remove unused local variable.
3575 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
3577 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
3578 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
3579 (mark_memory): Mark Lisp_Objects only if pointers might hide in
3580 objects, as mark_maybe_pointer will catch them otherwise.
3581 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
3582 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
3584 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
3586 Fix typo that broke non-Windows builds.
3587 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
3589 2012-04-07 Eli Zaretskii <eliz@gnu.org>
3591 Support building on MS-Windows with libxml2.
3593 * makefile.w32-in (OBJ2): Add xml.$(O).
3594 (GLOBAL_SOURCES): Add xml.c.
3595 ($(BLD)/xml.$(O)): New dependency list.
3597 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
3598 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
3599 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
3600 [!WINDOWSNT]: New macros.
3601 (init_libxml2_functions, libxml2_loaded_p): New functions.
3602 (parse_region): Call fn_xmlCheckVersion instead of using the macro
3603 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
3604 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
3605 Calls xmlCleanupParser only if libxml2 was loaded (or statically
3606 linked in).
3607 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
3608 Call init_libxml2_functions before calling libxml2 functions.
3609 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
3611 * emacs.c: Don't include libxml/parser.h.
3612 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
3613 xmlCleanupParser directly.
3615 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
3617 2012-04-07 Eli Zaretskii <eliz@gnu.org>
3619 * indent.c (Fvertical_motion): If there is a display string at
3620 point, use it.vpos to compute how many lines to backtrack after
3621 move_it_to point. (Bug#11133)
3623 2012-04-06 Eli Zaretskii <eliz@gnu.org>
3625 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
3626 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
3627 about subtle differences between FETCH_CHAR* and STRING_CHAR*
3628 macros related to unification of CJK characters. For the details,
3629 see the discussion following the message here:
3630 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
3632 2012-04-04 Chong Yidong <cyd@gnu.org>
3634 * keyboard.c (Vdelayed_warnings_list): Doc fix.
3636 2012-04-01 Eli Zaretskii <eliz@gnu.org>
3638 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
3639 instead of alloca. (Bug#11138)
3641 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
3643 * w32menu.c (is_simple_dialog): Properly check lisp types.
3644 (Bug#11141)
3646 2012-03-31 Eli Zaretskii <eliz@gnu.org>
3648 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
3649 position we get to after a call to move_it_to fails the
3650 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
3651 only if we wind up in a string from display property. (Bug#11063)
3653 * window.c (Fdelete_other_windows_internal): Invalidate the row
3654 and column information about mouse highlight, so that redisplay
3655 restores it after reallocating the glyph matrices. (Bug#7464)
3657 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
3658 string comes from a `display' text property, use the buffer
3659 position of that property as if we actually saw that position in
3660 the row's glyphs.
3661 (move_it_by_lines): Remove the assertion that
3662 "it->current_x == 0 && it->hpos == 0" which can be legitimately
3663 violated when there's a before-string at the beginning of a line.
3664 (Bug#11063)
3666 2012-03-30 Eli Zaretskii <eliz@gnu.org>
3668 * xdisp.c (append_space_for_newline): If the default face was
3669 remapped, use the remapped face for the appended newline.
3670 (extend_face_to_end_of_line): Use the remapped default face for
3671 extending the face to the end of the line.
3672 (display_line): Call extend_face_to_end_of_line when the default
3673 face was remapped. (Bug#11068)
3675 2012-03-29 Eli Zaretskii <eliz@gnu.org>
3677 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
3679 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
3681 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
3683 2012-03-27 Glenn Morris <rgm@gnu.org>
3685 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
3686 Doc fixes.
3688 2012-03-26 Kenichi Handa <handa@m17n.org>
3690 * dispextern.h (struct glyph): Fix previous change. Change the
3691 bit length of glyphless.ch to 25 (Bug#11082).
3693 2012-03-26 Chong Yidong <cyd@gnu.org>
3695 * keyboard.c (Vselection_inhibit_update_commands): New variable.
3696 (command_loop_1): Use it; inhibit selection update for
3697 handle-select-window too (Bug#8996).
3699 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
3701 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
3703 2012-03-25 Kenichi Handa <handa@m17n.org>
3705 * dispextern.h (struct glyph): Change the bit length of
3706 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
3708 2012-03-24 Eli Zaretskii <eliz@gnu.org>
3710 * s/ms-w32.h (tzname): Include time.h before redirecting to
3711 _tzname. Fixes the MSVC build. (Bug#9960)
3713 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
3715 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
3716 characters.
3718 * xterm.c (XTread_socket): Only modify handling_signal if
3719 !SYNC_INPUT. (Bug#11080)
3721 2012-03-23 Eli Zaretskii <eliz@gnu.org>
3723 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
3724 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
3725 when fetching a multibyte character consumes more bytes than
3726 CHAR_BYTES returns, due to unification of CJK characters in
3727 string_char. (Bug#11073)
3729 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
3731 * process.c (wait_reading_process_output): Handle pty disconnect
3732 by refraining from sending oneself a SIGCHLD (bug#10933).
3734 2012-03-22 Chong Yidong <cyd@gnu.org>
3736 * dispextern.h (struct it): New member string_from_prefix_prop_p.
3738 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
3739 Mark string as coming from a prefix property.
3740 (handle_face_prop): Use default face for prefix strings (Bug#4281).
3741 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
3743 2012-03-21 Chong Yidong <cyd@gnu.org>
3745 * xfaces.c (Vface_remapping_alist): Doc fix.
3747 2012-03-20 Eli Zaretskii <eliz@gnu.org>
3749 * w32proc.c (Fw32_set_console_codepage)
3750 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
3751 Doc fixes.
3753 2012-03-20 Chong Yidong <cyd@gnu.org>
3755 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
3756 to reflect default non-nil value of redisplay-dont-pause.
3758 2012-03-19 Kenichi Handa <handa@m17n.org>
3760 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
3761 it fit in a valid range (Bug#11003).
3763 2012-03-18 Eli Zaretskii <eliz@gnu.org>
3765 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
3766 that is not from display property, accept the row as a "cursor
3767 row" if one of the string's character has a non-nil `cursor'
3768 property. Fixes cursor positioning when there are newlines in
3769 overlay strings, e.g. in icomplete.el. (Bug#11035)
3771 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
3773 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
3775 2012-03-12 Chong Yidong <cyd@gnu.org>
3777 * eval.c (inhibit_lisp_code): Rename from
3778 inhibit_window_configuration_change_hook; move from window.c.
3780 * xfns.c (unwind_create_frame_1, Fx_create_frame):
3781 * window.c (run_window_configuration_change_hook)
3782 (syms_of_window): Callers changed.
3784 2012-03-11 Chong Yidong <cyd@gnu.org>
3786 * keymap.c (Fkey_description): Doc fix (Bug#9700).
3788 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
3790 2012-03-10 Chong Yidong <cyd@gnu.org>
3792 * frame.c (other_visible_frames): Don't assume the selected frame
3793 is visible (Bug#10955).
3795 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
3797 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
3799 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
3801 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
3802 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
3803 zero (Bug#10954).
3805 2012-03-03 Glenn Morris <rgm@gnu.org>
3807 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
3809 2012-03-02 Eli Zaretskii <eliz@gnu.org>
3811 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
3812 position past the first glyph_row that ends at ZV. (Bug#10902)
3813 (redisplay_window, next_element_from_string): Fix typos in
3814 comments.
3815 (redisplay_window): Pass to move_it_vertically the margin in
3816 pixels, not in screen lines.
3818 2012-03-02 Glenn Morris <rgm@gnu.org>
3820 * buffer.c (buffer-list-update-hook): Doc fix.
3822 2012-02-29 Eli Zaretskii <eliz@gnu.org>
3824 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
3825 push_it before setting up the iterator for the first overlay
3826 string, even if we have an empty string loaded.
3827 (next_overlay_string): If there's an empty string on the iterator
3828 stack, pop the stack. (Bug#10903)
3830 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
3832 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
3833 Suggested by Stefan Monnier in
3834 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
3835 * alloc.c (widen_to_Lisp_Object): New static function.
3836 (mark_memory): Also mark Lisp_Objects by fetching pointer words
3837 and widening them to Lisp_Objects. This would work even if
3838 USE_LSB_TAG is defined and wide integers are used, which might
3839 happen in a future version of Emacs.
3841 2012-02-25 Chong Yidong <cyd@gnu.org>
3843 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
3844 Doc fix.
3846 * xselect.c (Fx_selection_exists_p): Doc fix.
3847 (x_clipboard_manager_save_all): Print an informative message
3848 before saving to clipboard manager.
3850 2012-02-24 Chong Yidong <cyd@gnu.org>
3852 * keyboard.c (process_special_events): Handle all X selection
3853 requests in kbd_buffer, not just the next one (Bug#8869).
3855 2012-02-23 Chong Yidong <cyd@gnu.org>
3857 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
3858 call when setting menu-bar-lines and tool-bar-lines parameters.
3859 (unwind_create_frame_1): New helper function.
3861 * window.c (inhibit_window_configuration_change_hook): New var.
3862 (run_window_configuration_change_hook): Obey it.
3863 (syms_of_window): Initialize it.
3865 2012-02-22 Chong Yidong <cyd@gnu.org>
3867 * xterm.c (x_draw_image_relief): Add missing type check for
3868 Vtool_bar_button_margin (Bug#10743).
3870 2012-02-21 Chong Yidong <cyd@gnu.org>
3872 * fileio.c (Vfile_name_handler_alist): Doc fix.
3874 * buffer.c (Fget_file_buffer): Protect against invalid file
3875 handler return value.
3877 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
3879 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
3880 when computing $valmask.
3882 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
3883 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
3884 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
3885 It's useless in that case, and it can cause problems on hosts
3886 that allocate halves of EMACS_INT values separately.
3887 Reported by Dan Horák. Diagnosed by Andreas Schwab in
3888 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
3889 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
3890 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
3891 it avoids undefined behavior on hosts where shifting right by more
3892 than the word width has undefined behavior.
3894 2012-02-19 Chong Yidong <cyd@gnu.org>
3896 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
3897 (Funhandled_file_name_directory, Ffile_name_as_directory)
3898 (Fdirectory_file_name, Fexpand_file_name)
3899 (Fsubstitute_in_file_name): Protect against invalid file handler
3900 return values (Bug#10845).
3902 2012-02-18 Eli Zaretskii <eliz@gnu.org>
3904 * .gdbinit (pitx): Fix incorrect references to fields of the
3905 iterator stack.
3907 2012-02-17 Chong Yidong <cyd@gnu.org>
3909 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
3911 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
3913 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
3914 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.

4557 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
4558 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

4675 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
4676 is set, removing the need for VIRT_ADDRESS_VARIES.
4677 (PURE_P): Use a more-efficient implementation that needs just one

4684 consistency with the new puresize.h.
4685 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

4693 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
4694 behave as if the cursor position were at the window margin.
4696 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
4697 and the cursor position is out of bounds, behave as if the cursor
4698 position were at the window margin. (Bug#10075)
4700 2011-11-18 Chong Yidong <cyd@gnu.org>
4702 * window.c (Fwindow_combination_limit): Make first argument

4721 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
4723 * xdisp.c (row_hash): New function, body extracted from
4724 compute_line_metrics.
4725 (compute_line_metrics): Call row_hash, instead of computing the
4726 hash code inline.
4728 * dispnew.c (verify_row_hash): Call row_hash for computing the
4729 hash code of a row, instead of duplicating code from xdisp.c.
4731 * dispextern.h (row_hash): Add prototype.
4733 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
4735 * frame.c (delete_frame): Don't delete the terminal when the last

4784 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
4785 with user-defined heap size. Bump the default size of the temacs
4786 heap to 27MB, to avoid memory warning when running temacs.
4787 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
4789 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

4836 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
4838 Avoid some portability problems by eschewing 'extern inline' functions.
4839 The trivial performance wins aren't worth the portability hassles; see
4840 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
4841 et seq.

4890 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
4891 This is also needed for porting to any host where GC_MARK_STACK is
4892 not GC_MAKE_GCPROS_NOOPS.
4893 (which_symbols): Use it.
4895 2011-11-07 Kenichi Handa <handa@m17n.org>

4908 * xmenu.c (cleanup_widget_value_tree): New function.
4909 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

4916 (window_box_width, window_box_left, window_box_left_offset)
4917 (window_box_right, window_box_right_offset): Declare extern.
4918 Otherwise, these inline functions do not conform to C99 and
4919 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
4920 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
4921 * intervals.c (adjust_intervals_for_insertion)
4922 (adjust_intervals_for_deletion): Now extern, because otherwise the
4923 extern inline functions 'offset_intervals' couldn't refer to it.
4924 (static_offset_intervals): Remove.
4925 (offset_intervals): Rewrite using the old contents of
4926 static_offset_intervals. The old version didn't conform to C99
4927 because an extern inline function contained a reference to an
4928 identifier with static linkage.
4930 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
4932 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

4948 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
4949 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
4950 (Fwindow_vscroll): Doc fix.
4951 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
4952 argument, since it makes no sense to pass a live window and for
4953 consistency with window-child.

4980 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
4981 (unwind_create_frame): New function (Bug#9943).
4982 (Fx_create_frame): Restructure code to be more similar to the one in
4983 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
4984 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
4985 Move terminal->reference_count++ just before making the frame official
4986 (Bug#9943).
4988 * nsterm.m (x_free_frame_resources): New function.
4989 (x_destroy_window): Move code to x_free_frame_resources.
4991 * xfns.c (unwind_create_frame): Fix comment.
4992 (Fx_create_frame, x_create_tip_frame):
4993 Move terminal->reference_count++ just before making the frame
4994 official. Move initialization of image_cache_refcount and
4995 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

4999 Support MSVC build with newer versions of Visual Studio.
5000 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

5034 * xdisp.c (note_mouse_highlight): If either of
5035 previous/next-single-property-change returns nil, treat that as
5036 the beginning or the end of the buffer. (Bug#9955)
5038 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>

5061 Don't stop backward scan on the continuation glyph, even though
5062 its CHARPOS is positive.
5063 (mouse_face_from_buffer_pos, note_mouse_highlight):
5064 Rename cover_string to disp_string.
5066 2011-11-01 Martin Rudalics <rudalics@gmx.at>
5068 * window.c (temp_output_buffer_show): Don't use
5069 Vtemp_buffer_show_specifiers.
5070 (Vtemp_buffer_show_specifiers): Remove unused variable.
5072 2011-10-30 Eli Zaretskii <eliz@gnu.org>
5074 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
5075 past the beginning of the current glyph matrix.

5103 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
5105 * frame.h (MOUSE_HL_INFO): Remove excess parens.
5107 2011-10-29 Eli Zaretskii <eliz@gnu.org>

5123 2011-10-29 Glenn Morris <rgm@gnu.org>
5125 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
5126 Not clear what it was for, and it causes various bugs. (Bug#9839)
5128 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5130 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
5131 possible random value that matches one of those tested as
5132 condition to clear the mouse face.
5134 2011-10-28 Chong Yidong <cyd@gnu.org>
5136 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

5150 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5152 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem

5161 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
5162 New functions.
5163 (w32font_open_internal, compute_metrics):
5164 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
5165 instead of calling the "wide" APIs directly.
5167 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
5169 * w32.h (syms_of_w32font): Add prototype.
5171 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5173 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
5174 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
5175 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
5176 (Fmove_to_window_line): Doc fix.
5178 2011-10-27 Chong Yidong <cyd@gnu.org>
5180 * process.c (make_process): Set gnutls_state to NULL.
5182 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
5183 non-NULL, regardless of GNUTLS_INITSTAGE.

5209 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
5211 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
5213 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).

5231 current character, check also for next_en_type being WEAK_EN.
5232 (bidi_resolve_weak): Don't enter the expensive loop if the current
5233 position is before next_en_pos. Record the bidi type of the first
5234 non-ET, non-BN character we find, in addition to its position.
5235 (bidi_level_of_next_char): Invalidate next_en_type when
5236 next_en_pos is over-stepped.
5238 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
5240 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5241 * editfns.c: Rewrite current-time-zone so that it invokes
5242 the equivalent of (format-time-string "%Z") to get the time zone name.
5243 This fixes a bug when the time zone name contains characters that
5244 need converting from the system time locale to Emacs internal format.
5245 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5246 that patch fixed format-time-string to do the conversion, but
5247 I forgot to fix current-time-zone.
5248 (format_time_string): New function, containing most of
5249 what Fformat_time_string used to contain.
5250 (Fformat_time_string): Rewrite in terms of format_time_string.
5251 This doesn't change this function's behavior.
5252 (current-time-zone): Rewrite to use format_time_string.
5253 This fixes the bug reported by Michael Schierl in
5254 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5255 Jason Rumney's 2007-06-07 change worked around this bug, but
5256 didn't fix it.
5257 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5259 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5261 * xdisp.c (start_display): If the character at POS is displayed
5262 via a display vector, reset IT->current.dpvec_index to zero.
5263 (try_window_reusing_current_matrix): If a line ends in a display
5264 vector or the next line starts in a display vector, continue
5265 redrawing the window even though the character position of
5266 start_row was reached.
5267 (Bug#9771, part 2)
5269 2011-10-18 Chong Yidong <cyd@gnu.org>
5271 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5272 with nobreak-char-display too.
5274 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5276 Fix part 3 of bug#9771.
5277 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5278 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5279 non-neutral characters if the current character is a paragraph
5280 separator (a.k.a. Newline). This avoids running the same
5281 expensive loop twice, once when we consume the preceding newline
5282 and the other time when the line actually needs to be displayed.
5283 Avoid the loop when we see neutrals on the base embedding level
5284 following a character whose directionality is the same as the
5285 paragraph's. This avoids running the expensive loop when a line
5286 ends in a long sequence of neutrals, like control characters.
5287 Add assertion against STRONG_AL type. Slightly rearrange code
5288 that determines the type of a neutral given the first non-neutral
5289 that follows it.
5290 (bidi_level_of_next_char): Set next_en_pos to zero when
5291 invalidating its info.
5293 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5295 * xdisp.c (push_display_prop): Determine whether to record string
5296 or buffer position by IT->string, not by IT->method. Allow
5297 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5298 (move_it_vertically_backward): Don't look for character position
5299 immediately after the newline when in a continuation line.
5300 (Bug#9771, part 1)
5302 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5304 * window.c (coordinates_in_window): Rewrite and delabelize
5305 vertical border check. (Bug#5357) (Bug#9618)
5307 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5309 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5310 errors in XSetWindowBorder (bug#9310).
5312 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5314 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5315 avoid crash when xmalloc overrun checking is enabled.
5317 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5319 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5320 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5321 cursor motion with <left> and <right> arrow keys.
5323 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5324 some callers set that themselves.
5326 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5328 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5329 display string and the previous row comes from the same string and
5330 is empty. (Bug#9739) (Bug#9738)
5332 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5334 * doc.c (get_doc_string): Encode file name (bug#9735).
5336 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5338 * bidi.c (bidi_level_of_next_char):
5339 * xdisp.c (get_visually_first_element): Remove old incorrect
5340 comments regarding the Unicode Line Separator character.
5342 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5344 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5346 * alloc.c (Fgc_status): Do not access beyond zombies array
5347 boundary if nzombies > MAX_ZOMBIES.
5348 * alloc.c (dump_zombies): Add missing format specifier.
5350 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5352 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5353 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5355 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5356 Some packages use them to denote characters with modifiers.
5358 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5360 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5361 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5362 matching a pp-number. Rename parameter var to var1.
5364 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5366 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5368 2011-10-08 Glenn Morris <rgm@gnu.org>
5370 * callint.c (Fcall_interactively): Give a more explicit error for the
5371 'c' case with a non-character input. (Bug#8479)
5373 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5375 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5376 lines.
5377 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5378 lines that are hscrolled on the left.
5380 * dispnew.c (buffer_posn_from_coords): Account for a possible
5381 presence of header-line. (Bug#4426)
5383 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5385 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5386 Don't advertise functionality which we discourage or doesn't work.
5388 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5390 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5391 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5392 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5393 this makes Emacs dump core during garbage collection on rare
5394 occasions. sizeof is obviously inferior to offsetof here, so
5395 stick with offsetof.
5396 (GC_POINTER_ALIGNMENT): New macro.
5397 (mark_memory): Omit 3rd (offset) arg; caller changed.
5398 Don't assume EMACS_INT alignment is the same as pointer alignment.
5400 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5402 * keyboard.c (read_key_sequence_remapped): New var.
5403 (read_key_sequence): Compute remapping in the right buffer.
5404 (command_loop_1): Use read_key_sequence's remapping directly.
5406 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5408 * dired.c (file_name_completion): Don't expand file name.
5409 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5410 before checking file name handler.
5412 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5413 they've been requested explicitly (bug#9591).
5415 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5417 * keymap.c (Fsingle_key_description): Use make_specified_string
5418 instead of build_string to build string from push_key_description.
5419 (Bug#5193)
5421 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5423 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5424 This fixes a Y2038 bug on 64-bit hosts.
5425 * buffer.c (reset_buffer):
5426 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5427 (Fclear_buffer_auto_save_failure):
5428 Use 0, not -1, to represent an unset failure time, since time_t
5429 might not be signed.
5431 Remove dependency on glibc malloc internals.
5432 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5433 Move back here from lisp.h, but with their new implementations.
5434 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5435 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5436 * charset.c (charset_table_init): New static var.
5437 (syms_of_charset): Use it instead of xmalloc. This removes a
5438 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5439 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
5440 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5441 Move back to alloc.c.
5442 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5443 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
5445 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
5447 * nsterm.m (windowDidResize): Call x_set_window_size only when
5448 ns_in_resize is true. Otherwise set pixelwidth/height and
5449 call change_frame_size (Bug#9628).
5451 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5453 Port --enable-checking=all to Fedora 14 x86-64.
5454 * charset.c (syms_of_charset): Also account for glibc malloc's
5455 internal overhead when calculating the initial malloc maximum.
5457 Port --enable-checking=all to Fedora 14 x86.
5458 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5459 Move to lisp.h.
5460 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5461 (overrun_check_realloc, overrun_check_free):
5462 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5463 That way, xmalloc returns a properly-aligned pointer even if
5464 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
5465 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5466 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5467 into account when calculating the initial malloc maximum.
5468 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5469 Move here from alloc.c, so that charset.c can use it too.
5470 Properly align; the old code wasn't right for common 32-bit hosts
5471 when configured with --enable-checking=all.
5472 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5473 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
5475 2011-09-29 Eli Zaretskii <eliz@gnu.org>
5477 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
5478 use EDOM.
5480 2011-09-28 Eli Zaretskii <eliz@gnu.org>
5482 * xdisp.c (compute_display_string_end): If there's no display
5483 string at CHARPOS, return -1.
5485 * bidi.c (bidi_fetch_char): When compute_display_string_end
5486 returns a negative value, treat the character as a normal
5487 character not covered by a display string. (Bug#9624)
5489 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
5491 * lread.c (Fread_from_string): Fix typo in docstring.
5493 2011-09-27 Eli Zaretskii <eliz@gnu.org>
5495 * xdisp.c (handle_invisible_prop): If invisible text ends on a
5496 newline, reseat the iterator instead of bidi-iterating there one
5497 character at a time. (Bug#9610)
5498 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
5499 TO_CHARPOS if the bidi iterator is at base embedding level.
5501 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
5503 * lread.c (readevalloop): Use correct code for NBSP.
5504 (read1): Likewise. (Bug#9608)
5506 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
5508 * dbusbind.c (Fdbus_register_signal): When service is not
5509 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
5511 2011-09-25 Glenn Morris <rgm@gnu.org>
5513 * buffer.c (truncate-lines): Doc fix.
5515 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
5517 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
5518 (Fset_window_next_buffers): Doc fix.
5520 2011-09-24 Glenn Morris <rgm@gnu.org>
5522 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
5524 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
5526 Fix minor problems found by static checking.
5527 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
5528 * indent.c (Fvertical_motion): Fix == vs = typo.
5530 2011-09-24 Eli Zaretskii <eliz@gnu.org>
5532 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
5533 Default value is now t. Doc fix.
5535 * indent.c (Fvertical_motion): Compute and apply the overshoot
5536 logic when moving up, not only when moving down. Fix the
5537 confusing name and values of the it_overshoot_expected variable;
5538 logic changes accordingly. (Bug#9254) (Bug#9549)
5540 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
5541 CHARPOS is covered by a display string which includes newlines.
5542 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
5543 is covered by a display string with embedded newlines.
5545 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
5547 * dbusbind.c (Fdbus_register_signal): Add match rule to
5548 Vdbus_registered_objects_table. (Bug#9581)
5549 (Fdbus_register_method, Vdbus_registered_objects_table):
5550 Fix docstring.
5552 2011-09-24 Jim Meyering <meyering@redhat.com>
5554 do not ignore write error for any output size
5555 The previous change was incomplete.
5556 While it makes emacs --batch detect the vast majority of stdout
5557 write failures, errors were still ignored whenever the output size is
5558 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
5559 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
5560 && echo FAIL: ignored write error
5561 FAIL: ignored write error
5562 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
5563 && echo FAIL: ignored write error
5564 FAIL: ignored write error
5565 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
5567 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
5569 * emacs.c (Fkill_emacs): In noninteractive mode exit
5570 non-successfully if a write error occurred on stdout. (Bug#9574)
5572 2011-09-21 Eli Zaretskii <eliz@gnu.org>
5574 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
5575 the xassert test.
5577 * dispextern.h (struct it): Update the comment documenting what
5578 can it->OBJECT be.
5580 2011-09-20 Eli Zaretskii <eliz@gnu.org>
5582 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
5583 a display string, extend search for cursor position to end of row.
5584 (find_row_edges): If the row ends in a newline from a display
5585 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
5586 Handle the case of a display string with multiple newlines.
5587 (Fcurrent_bidi_paragraph_direction): Fix search for previous
5588 non-empty line. Fixes confusing cursor motion with arrow keys at
5589 the beginning of a line that starts with whitespace.
5591 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
5593 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
5594 (bug#9493).
5596 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
5598 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
5599 boolean (Bug#9154).
5601 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5603 * xdisp.c (display_line): Record maximum and minimum buffer
5604 positions even if no glyphs were produced (e.g., by a zero-width
5605 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
5606 buffer positions that will be removed from the glyph row because
5607 they don't fit.
5608 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
5609 column is beyond frame width: don't subtract 1 "pixel" when
5610 computing width of the stretch.
5611 (reseat_at_next_visible_line_start): Undo the change made on
5612 2011-09-17 that saved paragraph information and restored it after
5613 the call to `reseat'. (Bug#9545)
5615 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5617 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
5618 and turn window cursor on if cleared (Bug#9415).
5620 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
5622 * search.c (boyer_moore): Take unibyte characters from pattern
5623 literally. (Bug#9458)
5625 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5627 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
5629 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
5631 Fix minor problem found by static checking.
5632 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
5633 initialized, to pacify gcc -Wuninitialized.
5635 * fileio.c: Report proper errno when syscall falls.
5636 (Finsert_file_contents): Save and restore errno,
5637 so that report_file_error outputs the correct diagnostic.
5638 (Fwrite_region) [CLASH_DETECTION]: Likewise.
5640 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5642 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
5644 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5646 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
5647 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
5649 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5651 * xdisp.c (reseat_at_next_visible_line_start): Keep information
5652 about the current paragraph and restore it after the call to reseat.
5654 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
5655 (bidi_find_paragraph_start): Search back for paragraph beginning
5656 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
5657 (bidi_move_to_visually_next): Only trigger paragraph-related
5658 computations when the last character is a newline or at EOB, not
5659 just any NEUTRAL_B. (Bug#9470)
5661 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
5662 truncated lines if point is covered by a display string. (Bug#9524)
5664 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
5666 * xselect.c: Relax test for outgoing X longs (Bug#9498).
5667 (cons_to_x_long): New function.
5668 (lisp_data_to_selection_data): Use it. Correct the test for
5669 short-versus-long data; it was negated. Break out of vector
5670 loop, for efficiency, when a long datum is discovered.
5672 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
5674 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
5676 2011-09-16 Eli Zaretskii <eliz@gnu.org>
5678 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
5679 GCC PR/17406) by declaring this function with external scope.
5681 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5683 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
5684 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
5686 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
5688 * editfns.c (Fformat): Correctly handle text properties on "%%".
5690 2011-09-15 Eli Zaretskii <eliz@gnu.org>
5692 * xterm.c (x_draw_composite_glyph_string_foreground):
5693 * w32term.c (x_draw_composite_glyph_string_foreground):
5694 * term.c (encode_terminal_code):
5695 * composite.c (composition_update_it, get_composition_id):
5696 * xdisp.c (get_next_display_element)
5697 (fill_composite_glyph_string): Add comments about special meaning
5698 of TAB characters in a composition.
5700 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5702 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
5703 This occurs when processing a multibyte format.
5704 Problem reported by Wolfgang Jenker.
5706 2011-09-15 Johan Bockgård <bojohan@gnu.org>
5708 * xdisp.c (try_cursor_movement): Only check for exact match if
5709 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
5711 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5713 Remove unused external symbols.
5714 * dispextern.h (calc_pixel_width_or_height): Remove decl.
5715 * xdisp.c (calc_pixel_width_or_height): Now static.
5716 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
5717 * indent.c (check_display_width):
5718 * w32term.c: Fix comment to match code.
5719 * xterm.c, xterm.h (x_catching_errors): Remove.
5721 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5723 * xselect.c: Use signed conversions more consistently (Bug#9498).
5724 (selection_data_to_lisp_data): Assume incoming selection data are
5725 signed integers, not unsigned. This is to be consistent with
5726 outgoing selection data, which was modified to use signed integers
5727 in as part of the fix to Bug#9196 in response to Jan D.'s comment
5728 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
5729 expects long, not unsigned long.
5731 2011-09-14 Eli Zaretskii <eliz@gnu.org>
5733 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
5734 computation of loop end. Reported by Johan Bockgård
5735 <bojohan@gnu.org>.
5737 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
5739 * frame.c (Fother_visible_frames_p): Function deleted.
5741 2011-09-12 Eli Zaretskii <eliz@gnu.org>
5743 * indent.c (compute_motion): Process display vector front to back
5744 rather than the other way around. (Bug#2496)
5746 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5748 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
5750 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
5752 * minibuf.c (Fread_from_minibuffer): Doc fix.
5754 2011-09-11 Eli Zaretskii <eliz@gnu.org>
5756 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
5757 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
5759 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
5761 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
5762 value for non-existent files.
5764 2011-09-11 Eli Zaretskii <eliz@gnu.org>
5766 * fileio.c (Finsert_file_contents): If the file cannot be opened,
5767 set its "size" to -1. This will set the modtime_size field of
5768 the corresponding buffer to -1, which is what
5769 verify-visited-file-modtime expects for files that do not exist.
5770 (Bug#9139)
5772 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
5774 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
5775 here ...
5776 * lisp.h: ... from here. push_key_description is no longer
5777 defined in keyboard.c, so its declaration should not be in
5778 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
5779 logically belongs with push_key_description.
5781 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
5783 * buffer.h: Include <sys/types.h> instead of <time.h>.
5784 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
5785 Problem reported by Herbert J. Skuhra.
5787 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
5789 * xml.c (parse_region): Make the parsing work for
5790 non-comment-starting XML files again (bug#9144).
5792 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
5794 * image.c (gif_load): Fix calculation of bottom and right corner.
5795 (Bug#9468)
5797 2011-09-10 Eli Zaretskii <eliz@gnu.org>
5799 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
5800 redisplay in small windows.
5802 2011-09-09 Eli Zaretskii <eliz@gnu.org>
5804 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
5806 2011-09-08 Martin Rudalics <rudalics@gmx.at>
5808 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
5809 Operate on live windows only.
5811 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
5813 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
5815 2011-09-07 Eli Zaretskii <eliz@gnu.org>
5817 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
5818 only under bidi iteration.
5820 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
5822 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
5824 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
5826 isnan: Fix porting problem to Solaris 10 with bundled gcc.
5827 Without this fix, the command to link temacs failed due to an
5828 undefined symbol __builtin_isnan. This is because
5829 /usr/include/iso/math_c99.h #defines isnan(x) to
5830 __builtin_isnan(x), but the bundled gcc, which identifies itself
5831 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
5832 a __builtin_isnan.
5833 * floatfns.c (isnan): #undef, and then #define to a clone of
5834 what's in data.c.
5835 (Fisnan): Always define, since it's always available now.
5836 (syms_of_floatfns): Always define isnan at the Lisp level.
5838 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
5840 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
5842 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
5844 * fileio.c: Fix bugs with large file offsets (Bug#9428).
5845 The previous code assumed that file offsets (off_t values) fit in
5846 EMACS_INT variables, which is not true on typical 32-bit hosts.
5847 The code messed up by falsely reporting buffer overflow in cases
5848 such as (insert-file-contents "big" nil 1 2) into an empty buffer
5849 when "big" contains more than 2**29 bytes, even though this
5850 inserts just one byte and does not overflow the buffer.
5851 (Finsert_file_contents): Store file offsets as off_t
5852 values, not as EMACS_INT values. Check for overflow when
5853 converting between EMACS_INT and off_t. When checking for
5854 buffer overflow or for overlap, take the offsets into account.
5855 Don't use EMACS_INT for small values where int suffices.
5856 When checking for overlap, fix a typo: ZV was used where
5857 ZV_BYTE was intended.
5858 (Fwrite_region): Don't assume off_t fits into 'long'.
5859 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
5861 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
5863 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
5865 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
5867 sprintf-related integer and memory overflow issues (Bug#9412).
5869 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
5870 (esprintf, exprintf, evxprintf): New functions.
5871 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
5872 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
5873 (modify_event_symbol): Do not assume that the length of
5874 name_alist_or_stem is safe to alloca and fits in int.
5875 (Fexecute_extended_command): Likewise for function name and binding.
5876 (Frecursion_depth): Wrap around reliably on integer overflow.
5877 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
5878 since some callers pass EMACS_INT values.
5879 (Fsingle_key_description): Don't crash if symbol name contains more
5880 than MAX_ALLOCA bytes.
5881 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
5882 (get_minibuffer): Arg is now EMACS_INT, not int.
5883 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
5884 (esprintf, exprintf, evxprintf): New decls.
5885 * window.h (command_loop_level, minibuf_level): Reflect API changes.
5887 * dbusbind.c (signature_cat): New function.
5888 (xd_signature, Fdbus_register_signal):
5889 Do not overrun buffer; instead, report string overflow.
5891 * dispnew.c (add_window_display_history): Don't overrun buffer.
5892 Truncate instead; this is OK since it's just a log.
5894 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
5895 even if the time zone offset is outlandishly large.
5896 Don't mishandle offset == INT_MIN.
5898 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
5899 when creating daemon; the previous buffer-overflow check was incorrect.
5901 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
5902 which has the guts of the old verror function.
5904 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
5905 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
5907 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
5908 (font_unparse_xlfd): Don't blindly alloca long strings.
5909 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
5910 fits in int, when using sprintf. Use single snprintf to count
5911 length of string rather than counting it via multiple sprintfs;
5912 that's simpler and more reliable.
5913 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
5914 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
5915 sprintf, in case result does not fit in int.
5917 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
5918 (fontset_from_font): Print it.
5920 * frame.c (tty_frame_count): Now printmax_t, not int.
5921 (make_terminal_frame, set_term_frame_name): Print it.
5922 (x_report_frame_params): In X, window IDs are unsigned long,
5923 not signed long, so print them as unsigned.
5924 (validate_x_resource_name): Check for implausibly long names,
5925 and don't assume name length fits in 'int'.
5926 (x_get_resource_string): Don't blindly alloca invocation name;
5927 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
5928 not fit in int.
5930 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
5931 (xg_check_special_colors, xg_set_geometry):
5932 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
5934 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
5935 Use esprintf, not sprintf, in case result does not fit in int.
5937 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
5938 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
5939 it as a large positive number.
5940 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
5941 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
5943 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
5944 in case result does not fit in int.
5946 * print.c (float_to_string): Detect width overflow more reliably.
5947 (print_object): Make sprintf buffer a bit bigger, to avoid potential
5948 buffer overrun. Don't assume list length fits in 'int'. Treat
5949 print length of 0 as 0, not as infinity; to be consistent with other
5950 uses of print length in this function. Don't overflow print length
5951 index. Don't assume hash table size fits in 'long', or that
5952 vectorlike size fits in 'unsigned long'.
5954 * process.c (make_process): Use printmax_t, not int, to format
5955 process-name gensyms.
5957 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
5959 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
5960 to avoid potential buffer overrun.
5962 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
5963 if X resource line is longer than 512 bytes.
5965 * xfns.c (x_window): Make sprintf buffer a bit bigger
5966 to avoid potential buffer overrun.
5968 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
5970 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
5972 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
5974 Integer overflow fixes for scrolling, etc.
5975 Without these, Emacs silently mishandles large integers sometimes.
5976 For example, "C-u 4294967297 M-x recenter" was treated as if
5977 it were "C-u 1 M-x recenter" on a typical 64-bit host.
5979 * xdisp.c (try_window_id): Check Emacs fixnum range before
5980 converting to 'int'.
5982 * window.c (window_scroll_line_based, Frecenter):
5983 Check that an Emacs fixnum is in range before assigning it to 'int'.
5984 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
5985 values converted from Emacs fixnums.
5986 (Frecenter): Don't wrap around a line count if it is out of 'int'
5987 range; instead, treat it as an extreme value.
5988 (Fset_window_configuration, compare_window_configurations):
5989 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
5991 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
5992 that can exceed INT_MAX. Check that EMACS_INT value is in range
5993 before assigning it to the (possibly-narrower) index.
5994 (match_limit): Don't assume that a fixnum can fit in 'int'.
5996 * print.c (print_object): Use ptrdiff_t, not int, for index that can
5997 exceed INT_MAX.
5999 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6000 (Fvertical_motion): Don't wrap around LINES values that don't fit
6001 in 'int'. Instead, treat them as extreme values. This is good
6002 enough for windows, which can't have more than INT_MAX lines anyway.
6004 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6006 * Require libxml/parser.h to avoid compilation warning.
6008 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6010 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6011 since this reportedly can destroy thread storage.
6013 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6015 * syntax.c (find_defun_start): Update all cache variables if
6016 exiting early (Bug#9401).
6018 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6020 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6022 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6023 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6024 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6026 * term.c (tty_append_glyph): New function.
6027 (produce_stretch_glyph): Static function and its prototype deleted.
6029 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6030 Add prototypes.
6032 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6034 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6035 when checking :margin (Bug#9390).
6036 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6037 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6038 so that the name doesn't mislead. All uses changed.
6040 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6042 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6043 set_tty_hooks.
6045 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6047 * xdisp.c (move_it_to): Don't bail out early when reaching
6048 position beyond to_charpos, if we are scanning backwards.
6049 (move_it_vertically_backward): When DY == 0, make sure we get to
6050 the first character in the line after the newline.
6052 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6054 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6055 (ccl_driver): Do not generate an out-of-range pointer.
6056 (Fccl_execute_on_string): Remove unnecessary check for
6057 integer overflow, noted by Stefan Monnier in
6058 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6059 Remove a FIXME that didn't need fixing.
6060 Simplify the newly-introduced buffer reallocation code.
6062 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6064 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6066 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6068 Integer and memory overflow issues (Bug#9196).
6070 * doc.c (get_doc_string): Rework so that
6071 get_doc_string_buffer_size is the actual buffer size, rather than
6072 being 1 less than the actual buffer size; this makes xpalloc more
6073 convenient.
6075 * image.c (x_allocate_bitmap_record, cache_image):
6076 * xselect.c (Fx_register_dnd_atom):
6077 Simplify previous changes by using xpalloc.
6079 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6080 since either will do and ptrdiff_t is convenient with xpalloc.
6082 * charset.c (charset_table_size)
6083 (struct charset_sort_data.priority): Now ptrdiff_t.
6084 (charset_compare): Don't overflow if priorities differ greatly.
6085 (Fsort_charsets): Don't assume list length fits in int.
6086 Check for size-calculation overflow when allocating sort data.
6087 (syms_of_charset): Allocate an initial charset table that is
6088 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6090 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6092 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6093 The actual value is always <= INT_MAX, and leaving it unsigned made
6094 overflow checking harder.
6096 * dispextern.h (struct glyph_matrix.rows_allocated)
6097 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6098 with xpalloc. The values are still always <= INT_MAX.
6100 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6102 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6103 (SAFE_NALLOCA): New macro.
6105 * region-cache.c (struct boundary.pos, find_cache_boundary)
6106 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6107 (set_cache_region, invalidate_region_cache)
6108 (revalidate_region_cache, know_region_cache, region_cache_forward)
6109 (region_cache_backward, pp_cache):
6110 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6111 so that ptrdiff_t * can be passed to xpalloc.
6112 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6113 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6114 (pp_cache): Don't assume cache_len fits in int.
6115 * region-cache.h: Adjust extern decls to match.
6117 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6118 EMACS_INT, since either will do, for xpalloc.
6120 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6121 (xnmalloc, xnrealloc, xpalloc): New functions.
6123 * bidi.c (bidi_shelve_header_size): New constant.
6124 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6125 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6127 * bidi.c (bidi_cache_shrink):
6128 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6129 (overlay_strings):
6130 Don't update size of array until after memory allocation succeeds,
6131 because xmalloc/xrealloc may not return.
6132 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6133 now that we have proper integer overflow checking.
6134 (record_overlay_string, overlay_strings): Catch overflows when
6135 calculating size of overlay_str_buf.
6137 * callproc.c (Fcall_process): Check for size overflow when
6138 calculating size of args2.
6139 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6140 Normally we prefer signed values, but sticking with ptrdiff_t would
6141 require adding more-complicated checks.
6143 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6144 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6145 Redo buffer-overflow calculations to avoid integer overflow.
6146 Add a FIXME comment where memory seems to be over-allocated.
6148 * character.c (Fstring): Check for size-calculation overflow.
6150 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6151 unnecessary integer overflow. Check for size overflow.
6152 (encode_coding_object): Don't update size until xmalloc succeeds.
6154 * composite.c (get_composition_id): Check for overflow in glyph
6155 length calculations.
6157 Integer and memory overflow fixes for display code.
6158 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
6159 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6160 (scrolling_window): Check for overflow in size calculations.
6161 (line_draw_cost, realloc_glyph_pool, add_row_entry):
6162 Don't assume glyph table len fits in int.
6163 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
6164 (row_table_size): Now ptrdiff_t, not int.
6165 (scrolling_window): Avoid overflow in size calculations.
6166 Don't update size until allocation succeeds.
6167 * fns.c (concat): Check for overflow in size calculations.
6168 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
6169 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6170 (NEXT_ALMOST_PRIME_LIMIT): New constant.
6172 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
6173 (get_doc_string): Check for size calculation overflow.
6174 Don't update size until allocation succeeds.
6175 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
6176 EMACS_INT, where ptrdiff_t will do.
6177 (Fsubstitute_command_keys): Check for string overflow.
6179 * editfns.c (set_time_zone_rule): Don't assume environment length
6180 fits in int.
6181 (message_length): Now ptrdiff_t, not int.
6182 (Fmessage_box): Don't update size until allocation succeeds.
6183 Don't assume message length fits in int.
6184 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6186 * emacs.c (main): Do not reallocate argv, since there is a null at
6187 the end that can be overwritten, and this way there's no need to
6188 worry about size-calculation overflow.
6189 (sort_args): Check for size-calculation overflow.
6191 * eval.c (init_eval_once, grow_specpdl): Don't update size until
6192 alloc succeeds.
6193 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
6195 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
6196 (x_set_scroll_bar_width, x_figure_window_size):
6197 Check for integer overflow.
6198 (x_set_alpha): Do not assume XINT fits in int.
6200 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6201 This is for the members text_lines, text_cols, total_lines, total_cols,
6202 where the system imposes an 'int' limit.
6204 * fringe.c (Fdefine_fringe_bitmap):
6205 Don't update size until alloc works.
6207 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
6208 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
6210 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
6211 Check for size-calculation overflow.
6212 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6213 do, as we prefer signed integers.
6214 (id_to_widget.max_size, id_to_widget.used)
6215 (xg_store_widget_in_map, xg_remove_widget_from_map)
6216 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
6217 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
6218 Use and return ptrdiff_t, not int.
6219 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
6220 * gtkutil.h: Change prototypes to match the above.
6222 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
6223 are duplicate now that they've been promoted to lisp.h.
6224 (x_allocate_bitmap_record, x_alloc_image_color)
6225 (make_image_cache, cache_image, xpm_load):
6226 Don't update size until alloc is done.
6227 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
6228 (x_detect_edges):
6229 Check for size calculation overflow.
6230 (ct_colors_allocated_max): New constant.
6231 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
6232 overflow.
6234 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
6235 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
6236 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
6237 Use ptrdiff_t, not int, to count maps.
6238 (read_char_minibuf_menu_prompt): Check for overflow in size
6239 calculations. Don't update size until allocation succeeds.
6240 Redo calculations to avoid overflow.
6241 * keyboard.h: Change prototypes to match the above.
6243 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
6244 to count maps.
6245 (current_minor_maps): Check for size calculation overflow.
6246 * keymap.h: Change prototypes to match the above.
6248 * lread.c (read1, init_obarray): Don't update size until alloc done.
6250 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
6251 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
6253 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):

6267 (Fset_match_data): Don't assume list lengths fit in 'int'.
6269 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
6270 for command line length. Do not attempt to address one before the
6271 beginning of an array, as that's not portable.

6277 calculation overflow.
6278 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
6279 table lengths and related sizes. Don't update size until alloc
6280 done. Redo calculations to avoid overflow.
6281 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
6283 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
6284 subtracting pointers.

6299 Use ptrdiff_t, not int, for sizes.
6300 (Finternal_make_lisp_face, cache_face):
6301 Check for size calculation overflow.
6302 (cache_face): Treat size calculation overflows as if they were
6303 memory exhaustion (the usual treatment), rather than aborting.
6305 * xfns.c (x_encode_text, x_set_name_internal)
6306 (Fx_change_window_property): Use ptrdiff_t, not int, to count
6307 sizes, since they can exceed INT_MAX in size. Check for size
6308 calculation overflow.
6310 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
6311 (xg_select): Check for size calculation overflow.
6312 Don't update size until alloc done.
6314 * xrdb.c (get_environ_db): Don't assume path length fits in int,
6315 as sprintf is limited to int lengths.
6317 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
6318 (X_LONG_MIN): New macros.
6319 Use them to make the following changes clearer.
6320 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6321 This change doesn't affect the value now, but it may help remind
6322 future maintainers not to raise the value too much later.
6323 (SELECTION_QUANTUM): Remove, replacing with ...
6324 (selection_quantum): ... new function, which avoids overflow.
6325 All uses changed.
6326 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
6327 assumption that selection length fits in 'int'.
6328 (x_reply_selection_request, x_handle_selection_request)
6329 (x_get_window_property, receive_incremental_selection)
6330 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)

6335 Redo calculations to avoid overflow.
6336 (x_reply_selection_request): When sending hint, ceiling it at
6337 X_LONG_MAX rather than relying on wraparound overflow to send
6338 something.
6339 (x_get_window_property, receive_incremental_selection)
6340 (lisp_data_to_selection_data, x_property_data_to_lisp):
6341 Check for size-calculation overflow.

6344 Don't store size until memory allocation succeeds.
6345 (x_get_window_property): Plug memory leak on memory exhaustion.
6346 Don't double-block input; malloc is safe here. Don't assume 2**34
6347 - 4 fits in unsigned long. Add an xassert to check
6348 XGetWindowProperty overflow. Be more careful about overflow
6349 calculations, and distinguish size from memory overflow better.
6350 (receive_incremental_selection): When tracing, don't assume
6351 unsigned int is less than INT_MAX.
6352 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
6353 harmful) conversions of unsigned short to int.
6354 (lisp_data_to_selection_data): Don't assume that integers
6355 in the range -65535 through -1 fit in an X unsigned short.
6356 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
6357 result parameters unless successful. Rely on cons_to_unsigned
6358 to report problems with elements; the old code wasn't right anyway.
6359 (x_check_property_data): Check for int overflow; we cannot use
6360 a wider type due to X limits.
6361 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
6363 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
6365 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
6366 (x_term_init): Check for size calculation overflow.
6367 (x_color_cells): Don't store size until memory allocation succeeds.
6368 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
6369 Don't assume alloca size is less than MAX_ALLOCA.

6371 to int size).
6373 Use ptrdiff_t for composition IDs.
6374 * character.c (lisp_string_width):
6375 * composite.c (composition_table_size, n_compositions)

6392 * image.c (xpm_get_color_table_h):
6393 * lisp.h (hash_lookup, hash_put):
6394 * minibuf.c (Ftest_completion):
6395 Use ptrdiff_t for hash table indexes, not int (which is too
6396 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
6397 32-bit --with-wide-int hosts).
6399 * charset.c (Fdefine_charset_internal): Check for integer overflow.
6400 Add a FIXME comment about memory leaks.
6401 (syms_of_charset): Don't assume xmalloc returns.
6403 Don't assume that stated character widths fit in int.
6404 * character.c (Fchar_width, c_string_width, lisp_string_width):
6405 * character.h (CHAR_WIDTH):
6406 * indent.c (MULTIBYTE_BYTES_WIDTH):
6407 Use sanitize_char_width to avoid undefined and/or bad behavior
6408 with outlandish widths.
6409 * character.h (sanitize_tab_width): Rename from sanitize_width,
6410 now that we have two such functions. All uses changed.
6411 (sanitize_char_width): New inline function.
6413 Don't assume that tab-width fits in int.
6414 * character.h (sanitize_width): New inline function.
6415 (SANE_TAB_WIDTH): New macro.

6419 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
6421 * fileio.c: Integer overflow issues with file modes.
6422 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
6424 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

6429 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
6430 (x_send_scroll_bar_event): Likewise. Check that the size does not
6431 exceed limits imposed by XClientMessageEvent, as well as the usual
6432 ptrdiff_t and size_t limits.
6434 * keyboard.c: Overflow, signedness and related fixes.
6435 (make_lispy_movement): Use same integer type in forward decl
6436 that is used in the definition.
6437 (read_key_sequence, keyremap_step):
6438 Change bufsize argument back to int, undoing my 2011-03-30 change.
6439 We prefer signed types, and int is wide enough here.
6440 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6441 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
6442 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
6443 length, not size_t. Use ptrdiff_t for index, not int.
6444 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
6445 possibility of integer overflow.
6447 Overflow, signedness and related fixes for images.
6449 * dispextern.h (struct it.stack[0].u.image.image_id)
6450 (struct_it.image_id, struct image.id, struct image_cache.size)

6456 * nsmenu.m (update_frame_tool_bar):
6457 * xdisp.c (calc_pixel_width_or_height):
6458 * xfns.c (image_cache_refcount):
6459 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
6460 on typical 64-bit hosts.
6462 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6463 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

6468 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
6469 (lookup_image): Remove unnecessary tests.
6470 (xbm_image_p): Locals are now of int, not EMACS_INT,
6471 since parse_image_check makes sure they fit into int.
6472 (png_load, gif_load, svg_load_image):
6473 Prefer int to unsigned where either will do.
6474 (tiff_handler): New function, combining the cores of the
6475 old tiff_error_handler and tiff_warning_handler.
6476 This function is rewritten to use vsnprintf and thereby avoid
6477 stack buffer overflows. It uses only the features of vsnprintf
6478 that are common to both POSIX and native Microsoft.
6479 (tiff_error_handler, tiff_warning_handler): Use it.
6480 (tiff_load, gif_load, imagemagick_load_image):
6481 Don't assume :index value fits in 'int'.
6482 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
6483 (imagemagick_load_image): Check that crop parameters fit into
6484 the integer types that MagickCropImage accepts. Don't assume
6485 Vimagemagick_render_type has a nonnegative value. Don't assume
6486 size_t fits in 'long'.
6487 (gs_load): Use printmax_t to print the widest integers possible.
6488 Check for integer overflow when computing image height and width.
6490 2011-08-26 Eli Zaretskii <eliz@gnu.org>

6497 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
6498 the display spec is of the form `(space ...)'.
6499 (handle_display_spec): Return the value returned by
6500 handle_single_display_spec, not just 1 or zero.
6501 (handle_single_display_spec): If the display spec is of the form
6502 `(space ...)', and specifies display in the text area, return 2
6503 rather than 1.
6504 (try_cursor_movement): Check for the need to scroll more
6505 accurately, and prefer exact match for point under bidi.
6506 Don't advance `row' beyond the last row of the window.
6508 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
6509 into disp_prop; all users changed.
6511 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

6524 buffers, return left-to-right.
6525 (set_cursor_from_row): Consider candidate row a win if its glyph
6526 represents a newline and point is on that newline. Fixes cursor
6527 positioning on the newline at EOL of R2L text within L2R
6528 paragraph, and vice versa.
6529 (try_cursor_movement): Check continued rows, in addition to
6530 continuation rows. Fixes unwarranted scroll when point enters a
6531 continued line of R2L text within an L2R paragraph, or vice versa.
6532 (cursor_row_p): Consider the case of point being equal to
6533 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
6534 from the end of a short line to the beginning of a continued line
6535 of R2L text within L2R paragraph.
6536 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

6559 * xdisp.c (redisplay_window): When computing centering_position,
6560 account for the height of the header line. (Bug#8874)
6562 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
6563 instead of CHAR_TO_BYTE. Fixes a crash when a completion
6564 candidate is selected by the mouse, and that candidate has a
6565 composed character under the mouse.
6567 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
6568 coordinates reported by pos-visible-in-window-p for a composed

6578 consider it a hit if to_charpos is anywhere in the range of the
6579 composed buffer positions.
6581 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
6583 * image.c (gif_load): Don't assume that each subimage has the same
6584 dimensions as the base image. Handle disposal method that is
6585 "undefined" by the gif spec (Bug#9335).
6587 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
6589 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

6592 2011-08-19 Eli Zaretskii <eliz@gnu.org>
6594 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
6595 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
6596 from an Org mode buffer to a Speedbar frame.
6598 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
6599 a composition, take its buffer position from IT->cmp_it.charpos.
6600 Fixes cursor positioning at the beginning of a line that begins
6601 with a composed character.
6603 2011-08-18 Eli Zaretskii <eliz@gnu.org>
6605 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
6606 character bidirectional type, use STRONG_L instead. Fixes crashes
6607 in a buffer produced by `describe-categories'.
6609 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
6610 members before the level stack, so they would be saved and
6611 restored when copying iterator state. Fixes incorrect reordering
6612 around TABs covered by display properties.
6614 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
6616 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

6686 * xdisp.c (move_it_in_display_line_to): Don't invoke
6687 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
6688 ppos_it. Fixes vertical cursor motion when line beginning is
6689 covered by an image. (Bug#9296)
6691 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
6693 * nsterm.h (ns_run_ascript): Declare.

6696 * nsfns.m (as_script, as_result, as_status): New static variables.
6697 (ns_run_ascript): New function.
6698 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
6699 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
6700 the event loop. Get status from as_status (Bug#7276).
6702 * nsterm.m (sendEvent): If event is NSApplicationDefined and
6703 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
6704 the event loop (Bug#7276).
6706 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

6711 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
6712 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
6713 (QCgnutls_bootprop_verify_hostname_error)
6714 (QCgnutls_bootprop_callbacks_verify): Rename from
6715 Qgnutls_bootprop_..., all uses changed.
6717 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
6718 uses changed.
6720 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
6722 * xfaces.c (Qframe_set_background_mode): Now static.
6723 * dispextern.h (Qframe_set_background_mode): Remove decl.
6725 * process.c (Fnetwork_interface_info): Declare local only if needed.
6727 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
6729 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
6730 (Fnetwork_interface_list): Allocate in increments of bytes instead
6731 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
6732 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
6733 sockaddr.
6734 (struct ifflag_def): notrailers is smart on OSX.
6735 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
6736 Get hardware address with getifaddrs if available.
6738 2011-08-12 Eli Zaretskii <eliz@gnu.org>
6740 * xdisp.c (iterate_out_of_display_property): xassert that
6741 IT->position is set to within IT->object's boundaries. Break from
6742 the loop as soon as EOB is reached; avoids infloops in redisplay
6743 when IT->position is set up wrongly due to some bug.
6744 Set IT->current to match the bidi iterator unconditionally.
6745 (push_display_prop): Allow GET_FROM_STRING as IT->method on
6746 entry. Force push_it to save on the stack the current
6747 buffer/string position, to be restored by pop_it. Fix flags in
6748 the iterator structure wrt the object coming from a display
6749 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
6750 properties. (Bug#9284)
6752 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
6754 * fontset.c (fontset_get_font_group): Add proper type checks.
6755 (Bug#9172)
6757 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6759 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
6760 and LC_VERSION_MIN_MACOSX.
6761 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
6762 (dump_it) [LC_FUNCTION_STARTS]: Use it.
6764 2011-08-08 Eli Zaretskii <eliz@gnu.org>
6766 * xdisp.c (forward_to_next_line_start): Allow to use the
6767 no-display-properties-and-no-overlays under bidi display.
6768 Set disp_pos in the bidi iterator to avoid searches for display
6769 properties and overlays.
6771 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
6773 * editfns.c (Fset_time_zone_rule): Document relationship with the
6774 setenv function.
6776 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
6777 the font entity extracted from the cache (Bug#8109).
6779 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
6781 * composite.c (autocmp_chars): Don't reset point. That is done by
6782 restore_point_unwind (Bug#5984).
6784 2011-08-07 Juri Linkov <juri@jurta.org>
6786 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
6787 to show the arg `TIME' instead of `TIMEVAL'.
6789 2011-08-06 Eli Zaretskii <eliz@gnu.org>
6791 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
6792 display property strides EOL and includes a newline, as in
6793 longlines-mode. (Bug#9254)
6794 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
6795 word-wrap under bidirectional display. (Bug#9224)
6797 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
6798 is non-zero, even if the data buffer is NULL. Fixes a crash in
6799 vertical-motion with longlines-mode. (Bug#9254)
6801 2011-08-05 Eli Zaretskii <eliz@gnu.org>
6803 * bidi.c <bidi_cache_total_alloc>: Now static.
6804 (bidi_initialize): Initialize bidi_cache_total_alloc.
6806 * xdisp.c (display_line): Release buffer allocated for shelved bidi
6807 cache. (Bug#9221)
6809 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
6810 amount allocated this far in `bidi_cache_total_alloc'.
6811 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
6812 non-zero, only free the data buffer without restoring the cache
6813 contents. All callers changed.
6815 * dispextern.h (bidi_unshelve_cache): Update prototype.
6817 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
6818 (move_it_in_display_line, move_it_to)
6819 (move_it_vertically_backward, move_it_by_lines): Replace the call
6820 to xfree to an equivalent call to bidi_unshelve_cache.
6821 (move_it_in_display_line_to): Fix logic of returning
6822 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
6824 2011-08-05 Eli Zaretskii <eliz@gnu.org>
6826 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
6827 came from a string character with a `cursor' property. (Bug#9229)
6829 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
6831 * Makefile.in (LIB_PTHREAD): New variable.
6832 (LIBES): Add LIB_PTHREAD (Bug#9216).
6834 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
6835 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
6837 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
6839 * regex.c (re_iswctype): Remove some redundant boolean conversions.
6841 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
6843 * xterm.c (x_find_topmost_parent): New function.
6844 (x_set_frame_alpha): Find topmost parent window with
6845 x_find_topmost_parent and set the property there also (bug#9181).
6846 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
6848 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
6850 * callproc.c (Fcall_process): Avoid vfork clobbering
6851 the local vars buffer, coding_systems, current_dir.
6853 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
6855 * keymap.c (Fmake_composed_keymap): Move to subr.el.
6857 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
6859 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
6860 so that it is not optimized away.
6862 * xdisp.c (compute_display_string_pos): Remove unused local.
6864 2011-08-02 Eli Zaretskii <eliz@gnu.org>
6866 Fix slow cursor motion and scrolling in large buffers with
6867 selective display, like Org Mode buffers. (Bug#9218)
6869 * dispextern.h (struct bidi_it): New member disp_prop_p.
6871 * xdisp.c: Remove one-slot cache of display string positions.
6872 (compute_display_string_pos): Accept an additional argument
6873 DISP_PROP_P; callers changed. Scan at most 5K characters forward
6874 for a display string or property. If found, set DISP_PROP_P
6875 non-zero.
6877 * bidi.c (bidi_fetch_char): Accept an additional argument
6878 DISP_PROP_P, and pass it to compute_display_string_pos.
6879 Only handle text covered by a display string if DISP_PROP_P is returned
6880 non-zero. All callers of bidi_fetch_char changed.
6882 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
6884 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
6886 2010-12-03 Don March <don@ohspite.net>
6888 * keymap.c (Fdefine_key): Fix non-prefix key error message when
6889 last character M-[char] is translated to ESC [char] (bug#7541).
6891 2011-08-02 Kenichi Handa <handa@m17n.org>
6893 * lisp.h (uniprop_table): Extern it.
6895 * chartab.c (uniprop_table): Make it non-static.
6897 2011-08-01 Eli Zaretskii <eliz@gnu.org>
6899 * xdisp.c (forward_to_next_line_start): Accept additional argument
6900 BIDI_IT_PREV, and store into it the state of the bidi iterator had
6901 on the newline.
6902 (reseat_at_next_visible_line_start): Use the bidi iterator state
6903 returned by forward_to_next_line_start to restore the state of
6904 it->bidi_it after backing up to previous newline. (Bug#9212)
6906 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
6908 * regex.c (re_comp): Protoize.
6909 (re_exec): Fix return type.
6910 (regexec): Fix type of `ret'. (Bug#9203)
6912 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
6914 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
6915 This is needed if max-image-size is a floating-point number.
6917 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
6919 * print.c (print_object): Print empty symbol as ##.
6921 * lread.c (read1): Read ## as empty symbol.
6923 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
6925 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
6926 setting frame foreground color (Bug#9175).
6927 (x_set_background_color): Likewise.
6929 * nsmenu.m (-setText): Size tooltip dimensions precisely to
6930 contents (Bug#9176).
6931 (EmacsTooltip -init): Remove bezels and add shadows to
6932 tooltip windows.
6934 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
6935 or scroll bar (Bug#8470).
6937 * nsfont.m (nsfont_open): Remove assignment to voffset and
6938 unnecessary vars hshink, expand, hd, full_height, min_height.
6939 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
6941 * nsterm.h (nsfont_info): Remove voffset field.
6943 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
6945 Implement strike-through and overline on NextStep (Bug#8863).
6947 * nsfont.m (nsfont_open): Use underline position provided by font,
6948 instead of hard-coded value of 2.
6949 (nsfont_draw): Call ns_draw_text_decoration instead.
6951 * nsterm.h: Add declaration for ns_draw_text_decoration.
6953 * nsterm.m (ns_draw_text_decoration): New function for drawing
6954 underline, overline, and strike-through.
6955 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
6956 ns_draw_text_decoration. Change treatment of cursor drawing to
6957 accommodate underlining, etc.
6959 2011-07-28 Eli Zaretskii <eliz@gnu.org>
6961 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
6962 default.
6964 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
6966 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
6967 Without this fix, if a signal arrives just after memory fills up,
6968 'malloc' might be invoked reentrantly.
6970 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
6971 In other words, assume that every image size is allowed, on non-X
6972 hosts. This assumption is probably wrong, but it lets Emacs compile.
6974 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
6976 * regex.c (re_iswctype): Convert return values to boolean.
6978 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
6980 * xdisp.c (compute_display_string_pos): Don't use cached display
6981 string position if the buffer had its restriction changed.
6982 (Bug#9184)
6984 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
6986 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
6988 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
6990 Integer signedness and overflow and related fixes. (Bug#9079)
6992 * bidi.c: Integer size and overflow fixes.
6993 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
6994 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
6995 (bidi_cache_find_level_change, bidi_cache_ensure_space)
6996 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
6997 (bidi_find_other_level_edge):
6998 Use ptrdiff_t instead of EMACS_INT where either will do.
6999 This works better on 32-bit hosts configured --with-wide-int.
7000 (bidi_cache_ensure_space): Check for size-calculation overflow.
7001 Use % rather than repeated addition, for better worst-case speed.
7002 Don't set bidi_cache_size until after xrealloc returns, because it
7003 might not return.
7004 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7005 (bidi_cache_ensure_space): Also check that the bidi cache size
7006 does not exceed that of the largest Lisp string or buffer. See Eli
7007 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7009 * alloc.c (__malloc_size_t): Remove.
7010 All uses replaced by size_t. See Andreas Schwab's note
7011 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7013 * image.c: Improve checking for integer overflow.
7014 (check_image_size): Assume that f is nonnull, since
7015 it is always nonnull in practice. This is one less thing to
7016 worry about when checking for integer overflow later.
7017 (x_check_image_size): New function, which checks for integer
7018 overflow issues inside X.
7019 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7020 This removes the need for a memory_full check.
7021 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7022 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7023 (xbm_read_bitmap_data): Change locals back to 'int', since
7024 their values must fit in 'int'.
7025 (xpm_load_image, png_load, tiff_load):
7026 Invoke x_create_x_image_and_pixmap earlier,
7027 to avoid much needless work if the image is too large.
7028 (tiff_load): Treat overly large images as if
7029 x_create_x_image_and_pixmap failed, not as malloc failures.
7030 (gs_load): Use x_check_image_size.
7032 * gtkutil.c: Omit integer casts.
7033 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7034 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7036 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7038 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7039 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7040 would wrongly return t on a 64-bit host.
7042 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7043 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7044 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7045 and therefore cause GCC to emit a bogus diagnostic in some cases.
7047 * image.c: Integer signedness and overflow and related fixes.
7048 This is not an exhaustive set of fixes, but it's time to
7049 record what I've got.
7050 (lookup_pixel_color, check_image_size): Remove redundant decls.
7051 (check_image_size): Don't assume that arbitrary EMACS_INT values
7052 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7053 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7054 (tiff_load, imagemagick_load_image):
7055 Check for overflow in size calculations.
7056 (x_create_x_image_and_pixmap): Remove unnecessary test for
7057 xmalloc returning NULL; that can't happen.
7058 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7059 (xpm_color_bucket): Use better integer hashing function.
7060 (xpm_cache_color): Don't possibly over-allocate memory.
7061 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7062 (gif_memory_source):
7063 Use ptrdiff_t, not int or size_t, to record sizes.
7064 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7065 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7066 either works, as we prefer signed integers.
7067 (tiff_read_from_memory, tiff_write_from_memory):
7068 Return tsize_t, not size_t, since that's what the TIFF API wants.
7069 (tiff_read_from_memory): Don't fail simply because the read would
7070 go past EOF; instead, return a short read.
7071 (tiff_load): Omit no-longer-needed casts.
7072 (Fimagemagick_types): Don't assume size fits into 'int'.
7074 Improve hashing quality when configured --with-wide-int.
7075 * fns.c (hash_string): New function, taken from sxhash_string.
7076 Do not discard information about ASCII character case; this
7077 discarding is no longer needed.
7078 (sxhash-string): Use it. Change sig to match it. Caller changed.
7079 * lisp.h: Declare it.
7080 * lread.c (hash_string): Remove, since we now use fns.c's version.
7081 The fns.c version returns a wider integer if --with-wide-int is
7082 specified, so this should help the quality of the hashing a bit.
7084 * emacs.c: Integer overflow minor fix.
7085 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7086 Define only if GNU_LINUX.
7087 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7089 * dispnew.c: Integer signedness and overflow fixes.
7090 Remove unnecessary forward decls, that were a maintenance hassle.
7091 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7092 All uses changed.
7093 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7094 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7095 (prepare_desired_row, line_draw_cost):
7096 Use int, not unsigned, where either works.
7097 (save_current_matrix, restore_current_matrix):
7098 Use ptrdiff_t, not size_t, where either works.
7099 (init_display): Check for overflow more accurately, and without
7100 relying on undefined behavior.
7102 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7103 Remove, replacing with the new symbols in lisp.h. All uses changed.
7104 * fileio.c (make_temp_name):
7105 * filelock.c (lock_file_1, lock_file):
7106 * xdisp.c (message_dolog):
7107 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7108 Use pMd etc. instead.
7109 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7110 replacing the pWIDE etc. symbols removed from editfns.c.
7112 * keyboard.h (num_input_events): Now uintmax_t.
7113 This is (very slightly) less likely to mess up due to wraparound.
7114 All uses changed.
7116 * buffer.c: Integer signedness fixes.
7117 (alloc_buffer_text, enlarge_buffer_text):
7118 Use ptrdiff_t rather than size_t when either will do, as we prefer
7119 signed integers.
7121 * alloc.c: Integer signedness and overflow fixes.
7122 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7123 (__malloc_size_t): Default to size_t, not to int.
7124 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7125 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7126 Prefer ptrdiff_t to size_t when either would do, as we prefer
7127 signed integers.
7128 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7129 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7130 Now const. Initialize with values that are in range even if char
7131 is signed.
7132 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7133 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7134 These functions do the right thing with sizes > 2**32.
7135 (check_depth): Now ptrdiff_t, not int.
7136 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7137 Adjust to new way of storing sizes. Check for size overflow bugs
7138 in rest of code.
7139 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7140 slightly wrong anyway, as it missed one instance of
7141 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7142 (refill_memory_reserve): Omit needless cast to size_t.
7143 (mark_object_loop_halt): Mark as externally visible.
7145 * xselect.c: Integer signedness and overflow fixes.
7146 (Fx_register_dnd_atom, x_handle_dnd_message):
7147 Use ptrdiff_t, not size_t, since we prefer signed.
7148 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7149 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7150 x_dnd_atoms_size and x_dnd_atoms_length.
7152 * doprnt.c: Prefer signed to unsigned when either works.
7153 * eval.c (verror):
7154 * doprnt.c (doprnt):
7155 * lisp.h (doprnt):
7156 * xdisp.c (vmessage):
7157 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7158 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7159 prefer signed arithmetic to avoid comparison confusion.
7160 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7161 but is a bit tricky.
7163 Assume freestanding C89 headers, string.h, stdlib.h.
7164 * data.c, doprnt.c, floatfns.c, print.c:
7165 Include float.h unconditionally.
7166 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7167 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7168 * regex.c: Likewise for stddef.h, string.h.
7169 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7170 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7171 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7172 (STDC_HEADERS): Remove obsolete defines.
7173 * sysdep.c: Include limits.h unconditionally.
7175 Assume support for memcmp, memcpy, memmove, memset.
7176 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7177 * regex.c (memcmp, memcpy):
7178 Remove; we assume C89 now.
7180 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7181 (__malloc_safe_bcopy): Remove; no longer needed.
7183 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7184 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7185 well either way, and we prefer signed to unsigned.
7187 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7189 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7190 closes the connection while we're reading (bug#9182).
7192 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7194 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7195 are specified (Bug#9168).
7197 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7199 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7200 Found by GCC static checking and --with-wide-int on a 32-bit host.
7202 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7204 * xdisp.c (compute_display_string_pos): Fix logic of caching
7205 previous display string position. Initialize cached_prev_pos to
7206 -1. Fixes slow-down at the beginning of a buffer.
7208 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7210 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7211 for attrs[LFACE_FONTSET_INDEX].
7213 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7215 * xml.c (parse_region): Remove unused local
7216 that was recently introduced.
7218 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7220 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7221 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7223 * xdisp.c (move_it_in_display_line_to): Record the best matching
7224 position for TO_CHARPOS while scanning the line, and restore it on
7225 exit if none of the characters scanned was an exact match.
7226 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7227 when exact match is impossible due to invisible text, and the
7228 lines are truncated.
7230 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7232 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7233 for OSX >= 10.7.
7235 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7237 Fix a significant slow-down of cursor motion with C-n, C-p,
7238 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7239 auto-repeat under bidi redisplay in fontified buffers.
7240 * xdisp.c (compute_stop_pos_backwards): New function.
7241 (next_element_from_buffer): Call compute_stop_pos_backwards to
7242 find a suitable prev_stop when we find ourselves before
7243 base_level_stop.
7244 (reseat): Don't look for prev_stop, as that could mean a very long
7245 run.
7246 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7247 <cached_disp_overlay_modiff>: Cache for last found display string
7248 position.
7249 (compute_display_string_pos): Return the cached position if asked
7250 about the same buffer in the same area of character positions, and
7251 the buffer wasn't changed since the time the display string
7252 position was cached.
7254 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7256 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7257 is an integer, which is important for empty lines. (Bug#9149)
7259 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7261 * frame.c (Fmodify_frame_parameters): In tty case, update the
7262 default face if necessary (Bug#4238).
7264 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7266 * editfns.c (Fstring_to_char): No need to explain what a character
7267 is in the docstring (Bug#6576).
7269 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7271 * xml.c (parse_region): Make sure we always return a tree.
7273 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7275 * xml.c (parse_region): If a document contains only comments,
7276 return that, too.
7278 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7280 * xml.c (make_dom): Return comments, too.
7282 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7284 Port to OpenBSD.
7285 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7286 and the surrounding thread.
7287 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7288 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7289 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7290 timer goes off.
7291 * s/openbsd.h (BROKEN_SIGIO): Define.
7292 * unexelf.c (unexec) [__OpenBSD__]:
7293 Don't update the .mdebug section of the Alpha COFF symbol table.
7295 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7297 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7298 (bug#8460).
7300 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7302 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7303 This fixes some race conditions on the permissions of any newly
7304 created file.
7306 * alloc.c (valid_pointer_p): Use pipe, not open.
7307 This fixes some permissions issues when debugging.
7309 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7310 If fchown fails to set both uid and gid, try to set just gid,
7311 as that is sometimes allowed. Adjust the file's mode to eliminate
7312 setuid or setgid bits that are inappropriate if fchown fails.
7314 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7316 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7317 to compare Lisp_Objects.
7318 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7319 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7320 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7322 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7324 * lread.c (read_integer): Unread even EOF character.
7325 (read1): Likewise. Properly record start position of symbol.
7327 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7328 symbol character follows.
7330 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7332 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7333 This works around a problem with the previous change to Fcopy_file.
7334 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7335 and without this change, GCC might complain about discarding
7336 fchown's return value.
7338 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7340 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7342 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7344 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7346 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7348 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7349 it's used from the C level.
7351 * process.c: Use the same condition for POLL_FOR_INPUT in both
7352 keyboard.c and process.c (bug#1858).
7354 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7356 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7357 (Fgnutls_boot): Use it.
7359 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7361 * doc.c (Fsubstitute_command_keys): Revert last change.
7363 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7365 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7366 quotes the next character, and doesn't affect other longer
7367 sequences (bug#8935).
7369 * lread.c (syms_of_lread): Clarify that is isn't only
7370 `eval-buffer' and `eval-defun' that's affected by
7371 `lexical-binding' (bug#8460).
7373 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7375 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7376 bidi redisplay when a line includes both an image and is truncated.
7378 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7380 Fix minor problems found by static checking.
7381 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7382 (elsz): Now a signed constant, not a size_t var. We prefer signed
7383 types to unsigned, to avoid integer comparison confusion. Without
7384 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7385 "cannot optimize loop, the loop counter may overflow", a symptom
7386 of the confusion.
7387 * indent.c (Fvertical_motion): Mark locals as initialized.
7388 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7390 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7392 * search.c (Fre_search_backward): Mention `case-fold-search' in
7393 all the re_search_* functions (bug#8138).
7395 * keyboard.c (Fopen_dribble_file): Document when the file is
7396 closed (bug#8056).
7398 2011-07-14 Eli Zaretskii <eliz@gnu.org>
7400 * bidi.c (bidi_dump_cached_states): Fix format of displaying
7401 bidi_cache_idx.
7403 Support bidi reordering of display and overlay strings.
7404 * xdisp.c (compute_display_string_pos)
7405 (compute_display_string_end): Accept additional argument STRING.
7406 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
7407 (reseat_to_string): Initialize bidi_it->string.s and
7408 bidi_it->string.schars.
7409 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
7410 NULL (avoids a crash in bidi_paragraph_init).
7411 Initialize itb.string.lstring.
7412 (init_iterator): Call bidi_init_it only of a valid
7413 buffer position was specified. Initialize paragraph_embedding to
7414 L2R.
7415 (reseat_to_string): Initialize the bidi iterator.
7416 (display_string): If we need to ignore text properties of
7417 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7418 original value of -1 will not work with bidi.)
7419 (compute_display_string_pos): First arg is now struct
7420 `text_pos *'; all callers changed. Support display properties on
7421 Lisp strings.
7422 (compute_display_string_end): Support display properties on Lisp
7423 strings.
7424 (init_iterator, reseat_1, reseat_to_string): Initialize the
7425 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
7426 when iterating on a string not from display properties).
7427 (compute_display_string_pos, compute_display_string_end):
7428 Fix calculation of the object to scan. Fixes an error when using
7429 arrow keys.
7430 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7431 base_level_stop; instead, set base_level_stop to BEGV.
7432 Fixes crashes in vertical-motion.
7433 (next_element_from_buffer): Improve commentary for when
7434 the iterator is before prev_stop.
7435 (init_iterator): Initialize bidi_p from the default value of
7436 bidi-display-reordering, not from buffer-local value. Use the
7437 buffer-local value only if initializing for buffer iteration.
7438 (handle_invisible_prop): Support invisible properties on strings
7439 that are being bidi-reordered.
7440 (set_iterator_to_next): Support bidi reordering of C strings and
7441 Lisp strings.
7442 (next_element_from_string): Support bidi reordering of Lisp
7443 strings.
7444 (handle_stop_backwards): Support Lisp strings as well.
7445 (display_string): Support display of R2L glyph rows.
7446 Use IT_STRING_CHARPOS when displaying from a Lisp string.
7447 (init_iterator): Don't initialize it->bidi_p for strings
7448 here.
7449 (reseat_to_string): Initialize it->bidi_p for strings here.
7450 (next_element_from_string, next_element_from_c_string)
7451 (next_element_from_buffer): Add xassert's for correspondence
7452 between IT's object being iterated and it->bidi_it.string
7453 structure.
7454 (face_before_or_after_it_pos): Support bidi iteration.
7455 (next_element_from_c_string): Handle the case of the first string
7456 character that is not the first one in the visual order.
7457 (get_visually_first_element): New function, refactored from common
7458 parts of next_element_from_buffer, next_element_from_string, and
7459 next_element_from_c_string.
7460 (tool_bar_lines_needed, redisplay_tool_bar)
7461 (display_menu_bar): Force left-to-right direction. Add a FIXME
7462 comment for making that be controlled by a user option.
7463 (push_it, pop_it): Save and restore the state of the
7464 bidi iterator. Save and restore the bidi_p flag.
7465 (pop_it): Iterate out of display property for string iteration as
7466 well.
7467 (iterate_out_of_display_property): Support iteration over strings.
7468 (handle_single_display_spec): Set up it->bidi_it for iteration
7469 over a display string, and call bidi_init_it.
7470 (handle_single_display_spec, next_overlay_string)
7471 (get_overlay_strings_1, push_display_prop): Set up the bidi
7472 iterator for displaying display or overlay strings.
7473 (forward_to_next_line_start): Don't use the shortcut if
7474 bidi-iterating.
7475 (back_to_previous_visible_line_start): If handle_display_prop
7476 pushed the iterator stack, restore the internal state of the bidi
7477 iterator by calling bidi_pop_it same number of times.
7478 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
7479 and we are bidi-iterating, don't decrement the iterator position;
7480 instead, set the first_elt flag in the bidi iterator, to produce
7481 the same effect.
7482 (reseat_1): Remove redundant setting of string_from_display_prop_p.
7483 (push_display_prop): xassert that we are iterating a buffer.
7484 (push_it, pop_it): Save and restore paragraph_embedding member.
7485 (handle_single_display_spec, next_overlay_string)
7486 (get_overlay_strings_1, reseat_1, reseat_to_string)
7487 (push_display_prop): Set up the `unibyte' member of bidi_it.string
7488 correctly. Don't assume unibyte strings are not bidi-reordered.
7489 (compute_display_string_pos)
7490 (compute_display_string_end): Fix handling the case of C string.
7491 (push_it, pop_it): Save and restore from_disp_prop_p.

7494 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
7495 (pop_it): Call iterate_out_of_display_property only if we are
7496 popping after iteration over a string that came from a display
7497 property. Fix a typo in popping stretch info. Add an assertion
7498 for verifying that the iterator position is in sync with the bidi
7499 iterator.
7500 (handle_single_display_spec, get_overlay_strings_1)
7501 (push_display_prop): Fix initialization of paragraph direction for
7502 string when that of the parent object is not yet determined.
7503 (reseat_1): Call bidi_init_it to resync the bidi
7504 iterator with IT's position. (Bug#7616)
7505 (find_row_edges): If ROW->start.pos gives position
7506 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
7507 (handle_stop, back_to_previous_visible_line_start, reseat_1):
7508 Reset the from_disp_prop_p flag.
7509 (SAVE_IT, RESTORE_IT): New macros.
7510 (pos_visible_p, face_before_or_after_it_pos)
7511 (back_to_previous_visible_line_start)
7512 (move_it_in_display_line_to, move_it_in_display_line)
7513 (move_it_to, move_it_vertically_backward, move_it_by_lines)
7514 (try_scrolling, redisplay_window, display_line): Use them when
7515 saving a temporary copy of the iterator and restoring it back.
7516 (back_to_previous_visible_line_start, reseat_1)
7517 (init_iterator): Empty the bidi cache "stack".
7518 (move_it_in_display_line_to): If iterator ended up at
7519 EOL, but we never saw any buffer positions smaller than
7520 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
7521 motion in bidi-reordered lines.
7522 (move_it_in_display_line_to): Record prev_method and prev_pos
7523 immediately before the call to set_iterator_to_next. Fixes cursor
7524 motion in bidi-reordered lines with stretch glyphs and strings
7525 displayed in margins. (Bug#8133) (Bug#8867)
7526 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
7527 TO_CHARPOS.
7528 (pos_visible_p): Support positions in bidi-reordered lines.
7529 Save and restore bidi cache.
7531 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
7532 (bidi_paragraph_info): Delete unused struct.
7533 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
7534 (bidi_cache_start): New variable.
7535 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
7536 to zero.
7537 (bidi_cache_fetch_state, bidi_cache_search)
7538 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7539 (bidi_cache_find, bidi_peek_at_next_level)
7540 (bidi_level_of_next_char, bidi_find_other_level_edge)
7541 (bidi_move_to_visually_next): Compare cache index with
7542 bidi_cache_start rather than with zero.
7543 (bidi_fetch_char): Accept new argument STRING; all callers
7544 changed. Support iteration over a string. Support strings with
7545 display properties. Support unibyte strings. Fix the type of
7546 `len' according to what STRING_CHAR_AND_LENGTH expects.
7547 (bidi_paragraph_init, bidi_resolve_explicit_1)
7548 (bidi_resolve_explicit, bidi_resolve_weak)
7549 (bidi_level_of_next_char, bidi_move_to_visually_next):
7550 Support iteration over a string.
7551 (bidi_set_sor_type, bidi_resolve_explicit_1)
7552 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
7553 can now be zero (for strings); special values 0 and -1 were
7554 changed to -1 and -2, respectively.
7555 (bidi_char_at_pos): New function.
7556 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
7557 Call it instead of FETCH_MULTIBYTE_CHAR.

7559 initialized to valid values.
7560 (bidi_init_it): Don't initialize charpos and bytepos with invalid
7561 values.
7562 (bidi_level_of_next_char): Allow the sentinel "position" to pass
7563 the test for valid cached positions. Fix the logic for looking up
7564 the sentinel state in the cache. GCPRO the Lisp string we are
7565 iterating.
7566 (bidi_push_it, bidi_pop_it): New functions.
7567 (bidi_initialize): Initialize the bidi cache start stack pointer.
7568 (bidi_cache_ensure_space): New function, refactored from part of
7569 bidi_cache_iterator_state. Don't assume the required size is just
7570 one BIDI_CACHE_CHUNK away.

7581 (bidi_find_other_level_edge, bidi_cache_start_stack):
7582 All variables related to cache indices are now EMACS_INT.
7584 * dispextern.h (struct bidi_string_data): New structure.
7585 (struct bidi_it): New member `string'. Make flag members be 1-bit
7586 fields, and put them last in the struct.
7587 (compute_display_string_pos, compute_display_string_end):
7588 Update prototypes.

7640 Vx_lost_selection_functions to Frun_hook_with_args.
7642 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>

7645 The old code sometimes used this field without initializing it.
7647 * alloc.c (gc_sweep): Don't read past end of array.

7912 (clone_per_buffer_values): Don't assume that

7953 Random fixes. E.g., (random) never returned negative values.
7954 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
7955 subseconds part to the entropy, as that's a bit more random.
7956 Prefer signed to unsigned, since the signedness doesn't matter and
7957 in general we prefer signed. When given a limit, use a
7958 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
7959 latter isn't right if USE_2_TAGS_FOR_INTS.
7960 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
7961 not 0..VALMASK. Don't discard "excess" bits that random () returns.

7974 This is more efficient than Ffile_directory_p and avoids a minor race.
7976 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
7978 * buffer.c (Foverlay_put): Say what the return value is
7979 (bug#7835).

7982 is a directory before asking whether to use the file name
7983 (bug#7564).
7984 (barf_or_query_if_file_exists): Make the "File is a directory"
7985 error be more correct.
7987 * fns.c (Frequire): Remove the mention of the .gz files, since
7988 that's installation-specific, but keep the mention of

8004 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
8005 Also (re)move comments that are misplaced or no longer relevant.
8007 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>

8106 * eval.c (struct backtrace): Simplify and port the data structure.
8107 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8108 signed bit field, as this assumption is not portable and it makes
8109 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8110 "char debug_on_exit : 1" as this is not portable either; instead,
8111 use the portable "unsigned int debug_on_exit : 1". Remove unused
8112 member evalargs. Remove obsolete comments about cc bombing out.
8114 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

8149 clearly which files are directly included by each source file,
8150 and not through other includes.
8152 2011-06-27 Martin Rudalics <rudalics@gmx.at>
8154 * buffer.c (Qclone_number): Declare static and DEFSYM it.
8155 (sort_overlays, overlay_strings): When an overlay's clone number

8160 (Fwindow_hchild): Rename to Fwindow_left_child.
8161 (Fwindow_next): Rename to Fwindow_next_sibling.
8162 (Fwindow_prev): Rename to Fwindow_prev_sibling.
8163 (resize_window_check): Rename to window_resize_check.

8182 (emacs_fixed_new): Set priv->f to argument.
8183 (emacs_fixed_get_preferred_width)
8184 (emacs_fixed_get_preferred_height): Use min_width/height from
8185 frames size_hint to set minimum and natural (Bug#8919).
8186 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
8187 and use min_width/height from frames size_hint to set
8188 min_width/height (Bug#8919).
8190 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

8196 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
8197 bidi_at_paragraph_end, since fast_looking_at doesn't like to be

8206 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
8208 Use gnulib's dup2 module instead of rolling our own.
8209 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

8276 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
8278 Integer and buffer overflow fixes (Bug#8873).
8280 * print.c (printchar, strout): Check for string overflow.
8281 (PRINTPREPARE, printchar, strout):
8282 Don't set size unless allocation succeeds.
8284 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
8285 for sizes. Check for string overflow more accurately.
8286 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
8288 * macros.c: Integer and buffer overflow fixes.
8289 * keyboard.h (struct keyboard.kbd_macro_bufsize):
8290 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

8296 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
8298 * lread.c: Integer overflow fixes.
8299 (read_integer): Radix is now EMACS_INT, not int,
8300 to improve quality of diagnostics for out-of-range radices.
8301 Calculate buffer size correctly for out-of-range radices.
8302 (read1): Check for integer overflow in radices, and in
8303 read-circle numbers.
8304 (read_escape): Avoid int overflow.
8305 (Fload, openp, read_buffer_size, read1)
8306 (substitute_object_recurse, read_vector, read_list, map_obarray):

8318 out-of-range doc string lengths.
8319 (read_list): Don't assume file position fits in int.
8320 (read_escape): Check for hex character overflow.
8322 2011-06-22 Leo Liu <sdl.web@gmail.com>
8324 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
8325 Move to minibuffer.el.
8327 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8329 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
8330 The following patches are for when GLYPH_DEBUG && !XASSERT.
8331 * dispextern.h (trace_redisplay_p, dump_glyph_string):
8332 * dispnew.c (flush_stdout):
8333 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
8334 Mark as externally visible.
8335 * dispnew.c (check_window_matrix_pointers): Now static.
8336 * dispnew.c (window_to_frame_vpos):
8337 * xfns.c (unwind_create_frame):
8338 * xterm.c (x_check_font): Remove unused local.
8339 * scroll.c (CHECK_BOUNDS):
8340 * xfaces.c (cache_fache): Rename local to avoid shadowing.
8341 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8342 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8343 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8344 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8345 Now static.
8346 (debug_method_add): Use va_list and vsprintf rather than relying
8347 on undefined behavior with wrong number of arguments.
8348 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8349 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8350 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8351 since we're not interested in debugging glyphs with old libraries.
8352 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8353 GCC 4.6.0's static checking.
8355 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8357 Integer overflow and signedness fixes (Bug#8873).

8366 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
8367 (x_create_bitmap_from_xpm_data):
8368 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
8369 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
8370 (.bitmaps_last):
8371 * xfaces.c (load_pixmap):
8372 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
8373 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
8374 (.bitmaps_last, struct x_output.icon_bitmap):
8375 Use ptrdiff_t, not int, for bitmap indexes.
8376 (x_allocate_bitmap_record): Check for size overflow.

8389 Use ptrdiff_t, not int, for sizes.
8390 (overlays_at, overlays_in): Check for size-calculation overflow.
8392 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8394 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8395 (x_session_initialize): Do not assume string length fits in int.
8397 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8398 This is unlikely, but can occur if DPI is outlandish.
8400 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8401 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8403 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
8404 * xrdb.c (magic_file_p, search_magic_path):
8405 Omit last arg SUFFIX; it was always 0. All callers changed.
8406 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
8408 * xfont.c (xfont_match): Avoid need for strlen.
8410 * xfns.c: Don't assume strlen fits in int.

8413 * xdisp.c (message_log_check_duplicate): Return intmax_t,
8414 not unsigned long, as we prefer signed integers. All callers changed.
8415 Detect integer overflow in repeat count.
8416 (message_dolog): Don't assume print length fits in 39 bytes.
8417 (display_mode_element): Don't assume strlen fits in int.
8419 * termcap.c: Don't assume sizes fit in int and never overflow.
8420 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
8421 (gobble_line): Check for size-calculation overflow.
8423 * minibuf.c (Fread_buffer):
8424 * lread.c (intern, intern_c_string):
8425 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
8426 Don't assume string length fits in int.
8428 * keyboard.c (parse_tool_bar_item):

8435 Don't assume integer property fits in fixnum.
8436 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
8438 * filelock.c: Fix some buffer overrun and integer overflow issues.
8439 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
8440 Reformulate so as not to need the command string.
8441 Invoke gzip -cd rather than gunzip, as it's more portable.
8442 (lock_info_type, lock_file_1, lock_file):
8443 Don't assume pid_t and time_t fit in unsigned long.
8444 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8445 (current_lock_owner): Prefer signed type for sizes.
8446 Use memcpy, not strncpy, where memcpy is what is really wanted.
8447 Don't assume (via atoi) that time_t and pid_t fit in int.
8448 Check for time_t and/or pid_t out of range, e.g., via a network share.
8449 Don't alloca where an auto var works fine.
8451 * fileio.c: Fix some integer overflow issues.
8452 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8453 Don't assume string length fits in int.
8454 (directory_file_name): Don't assume string length fits in long.
8455 (make_temp_name): Don't assume pid fits in int, or that its print
8456 length is less than 20.
8458 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8460 * coding.c (make_subsidiaries): Don't assume string length fits in int.
8462 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

8476 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8478 * lread.c (invalid_syntax): Omit length argument.
8479 All uses changed. This doesn't fix a bug, but it simplifies the
8480 code away from its former Hollerith-constant appearance, and it's
8481 one less 'int' to worry about when looking at integer-overflow issues.
8482 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8484 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8485 This didn't break anything, but it didn't help either.
8486 It's confusing to put a bogus integer in a place where the actual
8487 value does not matter.
8488 (LIST_END_P): Remove unused macro and its bogus comment.
8489 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8491 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8492 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8493 implementation.
8494 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8495 We prefer signed types, and the value cannot exceed the EMACS_INT
8496 range anyway (because otherwise the length would not be representable).
8497 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8498 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8499 This avoids a GCC warning when WIDE_EMACS_INT.
8501 * indent.c (sane_tab_width): New function.
8502 (current_column, scan_for_column, Findent_to, position_indentation)
8503 (compute_motion): Use it. This is just for clarity.
8504 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8506 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8508 * lisp.h (lint_assume): New macro.
8509 * composite.c (composition_gstring_put_cache):
8510 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8512 * editfns.c, insdel.c:
8513 Omit unnecessary forward decls, to simplify future changes.
8515 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8517 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8519 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8520 Use much-faster test for byte-length change.
8521 Don't assume string byte-length fits in 'int'.
8522 Check that character arg fits in 'int'.
8523 (mapcar1): Declare byte as byte, for clarity.
8525 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
8527 * fns.c (concat): Catch string overflow earlier.
8528 Do not rely on integer wraparound.
8530 * dispextern.h (struct it.overlay_strings_charpos)
8531 (struct it.selective): Now EMACS_INT, not int.
8532 * xdisp.c (forward_to_next_line_start)
8533 (back_to_previous_visible_line_start)
8534 (reseat_at_next_visible_line_start, next_element_from_buffer):
8535 Don't arbitrarily truncate the value of 'selective' to int.
8537 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
8539 * composite.c: Don't truncate sizes to 'int'.
8540 (composition_gstring_p, composition_reseat_it)
8541 (composition_adjust_point): Use EMACS_INT, not int.
8542 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
8543 not EMACS_UINT, for indexes.
8545 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
8547 * buffer.c: Include <verify.h>.
8548 (struct sortvec.priority, struct sortstr.priority):
8549 Now EMACS_INT, not int.
8550 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
8551 (struct sortstr.size, record_overlay_string)
8552 (struct sortstrlist.size, struct sortlist.used):
8553 Don't truncate size to int.
8554 (record_overlay_string): Check for size-calculation overflow.
8555 (init_buffer_once): Check at compile-time, not run-time.
8557 2011-06-22 Jim Meyering <meyering@redhat.com>
8559 Don't leak an XBM-image-sized buffer
8560 * image.c (xbm_load): Free the image buffer after using it.
8562 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
8564 Port to Sun C.
8565 * composite.c (find_automatic_composition): Omit needless 'return 0;'
8566 that Sun C diagnosed.
8567 * fns.c (secure_hash): Fix pointer signedness issue.
8568 * intervals.c (static_offset_intervals): New function.
8569 (offset_intervals): Use it.
8571 2011-06-21 Leo Liu <sdl.web@gmail.com>
8573 * deps.mk (fns.o):
8574 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
8575 sha512.h.
8577 * fns.c (secure_hash): Rename from crypto_hash_function and change
8578 the first arg to accept symbols.
8579 (Fsecure_hash): New primitive.
8580 (syms_of_fns): New symbols.
8582 2011-06-20 Deniz Dogan <deniz@dogan.se>
8584 * process.c (Fset_process_buffer): Clarify return value in
8585 docstring.
8587 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
8589 * dispnew.c (add_window_display_history): Use BVAR.
8591 * xdisp.c (debug_method_add): Use BVAR.
8592 (check_window_end, dump_glyph_matrix, dump_glyph)
8593 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
8595 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
8596 Likewise.
8598 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
8599 check till after the cache is created in init_frame_faces.
8601 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
8603 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
8605 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
8607 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
8608 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
8609 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
8611 Improve buffer-overflow checking (Bug#8873).
8612 * fileio.c (Finsert_file_contents):
8613 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
8614 Remove the old (too-loose) buffer overflow checks.
8615 They weren't needed, since make_gap checks for buffer overflow.
8616 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
8617 The old code merely checked for Emacs fixnum overflow, and relied
8618 on undefined (wraparound) behavior. The new code avoids undefined
8619 behavior, and also checks for ptrdiff_t and/or size_t overflow.
8621 * editfns.c (Finsert_char): Don't dump core with very negative counts.
8622 Tune. Don't use wider integers than needed. Don't use alloca.
8623 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
8625 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
8627 * insdel.c, lisp.h (buffer_overflow): New function.
8628 (insert_from_buffer_1, replace_range, replace_range_2):
8629 * insdel.c (make_gap_larger):
8630 * editfns.c (Finsert_char):
8631 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
8633 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
8635 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
8637 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
8639 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
8640 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
8642 * fileio.c: Don't assume EMACS_INT fits in off_t.
8643 (emacs_lseek): New static function.
8644 (Finsert_file_contents, Fwrite_region): Use it.
8645 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
8647 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
8649 * fns.c: Don't overflow int when computing a list length.
8650 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
8651 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
8652 truncation on 64-bit hosts. Check for QUIT every
8653 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
8654 faster and is responsive enough.
8655 (Flength): Report an error instead of overflowing an integer.
8656 (Fsafe_length): Return a float if the value is not representable
8657 as a fixnum. This shouldn't happen except in contrived situations.
8658 (Fnthcdr, Fsort): Don't assume list length fits in int.
8659 (Fcopy_sequence): Don't assume vector length fits in int.
8661 * alloc.c: Check that resized vectors' lengths fit in fixnums.
8662 (header_size, word_size): New constants.
8663 (allocate_vectorlike): Don't check size overflow here.
8664 (allocate_vector): Check it here instead, since this is the only
8665 caller of allocate_vectorlike that could cause overflow.
8666 Check that the new vector's length is representable as a fixnum.
8668 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
8669 The previous code was bogus. For example, next_almost_prime (32)
8670 returned 39, which is undesirable as it is a multiple of 3; and
8671 next_almost_prime (24) returned 25, which is a multiple of 5 so
8672 why was the code bothering to check for multiples of 7?
8674 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
8676 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
8678 Variadic C functions now count arguments with ptrdiff_t.
8679 This partly undoes my 2011-03-30 change, which replaced int with size_t.
8680 Back then I didn't know that the Emacs coding style prefers signed int.
8681 Also, in the meantime I found a few more instances where arguments
8682 were being counted with int, which may truncate counts on 64-bit
8683 machines, or EMACS_INT, which may be unnecessarily wide.
8684 * lisp.h (struct Lisp_Subr.function.aMANY)
8685 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
8686 Arg counts are now ptrdiff_t, not size_t.
8687 All variadic functions and their callers changed accordingly.
8688 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
8689 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
8690 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
8691 * callint.c (Fcall_interactively): Check arg count for overflow,
8692 to avoid potential buffer overrun. Use signed char, not 'int',
8693 for 'varies' array, so that we needn't bother to check its size
8694 calculation for overflow.
8695 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
8696 * eval.c (apply_lambda):
8697 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
8698 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
8699 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
8701 * callint.c (Fcall_interactively): Don't use index var as event count.
8703 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
8704 * mem-limits.h (SIZE): Remove; no longer used.
8706 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
8708 Remove unnecessary casts.
8709 * xterm.c (x_term_init):
8710 * xfns.c (x_set_border_pixel):
8711 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
8712 These aren't needed now that we assume ANSI C.
8714 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
8715 It's more likely to cause problems (due to unsigned overflow)
8716 than to cure them.
8718 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
8720 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
8722 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
8724 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
8726 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
8728 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
8730 GLYPH_CODE_FACE returns EMACS_INT, not int.
8731 * dispextern.h (merge_faces):
8732 * xfaces.c (merge_faces):
8733 * xdisp.c (get_next_display_element, next_element_from_display_vector):
8734 Don't assume EMACS_INT fits in int.
8736 * character.h (CHAR_VALID_P): Remove unused parameter.
8737 * fontset.c, lisp.h, xdisp.c: All uses changed.
8739 * editfns.c (Ftranslate_region_internal): Omit redundant test.
8741 * fns.c (concat): Minor tuning based on overflow analysis.
8742 This doesn't fix any bugs. Use int to hold character, instead
8743 of constantly refetching from Emacs object. Use XFASTINT, not
8744 XINT, for value known to be a character. Don't bother comparing
8745 a single byte to 0400, as it's always less.
8747 * floatfns.c (Fexpt):
8748 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
8750 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
8751 for characters.
8753 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
8755 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
8756 Without this fix, on a 64-bit host (aset S 0 4294967386) would
8757 incorrectly succeed when S was a string, because 4294967386 was
8758 truncated before it was used.
8760 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
8761 Otherwise, an out-of-range integer could cause undefined behavior
8762 on a 64-bit host.
8764 * composite.c: Use int, not EMACS_INT, for characters.
8765 (fill_gstring_body, composition_compute_stop_pos): Use int, not
8766 EMACS_INT, for values that are known to be in character range.
8767 This doesn't fix any bugs but is the usual style inside Emacs and
8768 may generate better code on 32-bit machines.
8770 Make sure a 64-bit char is never passed to ENCODE_CHAR.
8771 This is for reasons similar to the recent CHAR_STRING fix.
8772 * charset.c (Fencode_char): Check that character arg is actually
8773 a character. Pass an int to ENCODE_CHAR.
8774 * charset.h (ENCODE_CHAR): Verify that the character argument is no
8775 wider than 'int', as a compile-time check to prevent future regressions
8776 in this area.
8778 * character.c (char_string): Remove unnecessary casts.
8780 Make sure a 64-bit char is never passed to CHAR_STRING.
8781 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
8782 by silently ignoring the top 32 bits, allowing some values
8783 that were far too large to be valid characters.
8784 * character.h: Include <verify.h>.
8785 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
8786 arguments are no wider than unsigned, as a compile-time check
8787 to prevent future regressions in this area.
8788 * data.c (Faset):
8789 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
8790 (Fsubst_char_in_region):
8791 * fns.c (concat):
8792 * xdisp.c (decode_mode_spec_coding):
8793 Adjust to CHAR_STRING's new requirement.
8794 * editfns.c (Finsert_char, Fsubst_char_in_region):
8795 * fns.c (concat): Check that character args are actually
8796 characters. Without this test, these functions did the wrong
8797 thing with wildly out-of-range values on 64-bit hosts.
8799 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
8800 These casts should not be needed on 32-bit hosts, either.
8801 * keyboard.c (read_char):
8802 * lread.c (Fload): Remove casts to unsigned.
8804 * lisp.h (UNSIGNED_CMP): New macro.
8805 This fixes comparison bugs on 64-bit hosts.
8806 (ASCII_CHAR_P): Use it.
8807 * casefiddle.c (casify_object):
8808 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
8809 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
8810 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
8811 * dispextern.h (FACE_FROM_ID):
8812 * keyboard.c (read_char): Use UNSIGNED_CMP.
8814 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
8815 not to EMACS_INT, to avoid GCC warning.
8817 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
8819 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
8820 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
8821 isn't needed on 32-bit machines.
8823 * buffer.c (Fgenerate_new_buffer_name):
8824 Use EMACS_INT for count, not int.
8825 (advance_to_char_boundary): Return EMACS_INT, not int.
8827 * data.c (Qcompiled_function): Now static.
8829 * window.c (window_body_lines): Now static.
8831 * image.c (gif_load): Rename local to avoid shadowing.
8833 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
8834 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
8835 * alloc.c (make_save_value): Integer argument is now of type
8836 ptrdiff_t, not int.
8837 (mark_object): Use ptrdiff_t, not int.
8838 * lisp.h (pD): New macro.
8839 * print.c (print_object): Use it.
8841 * alloc.c: Use EMACS_INT, not int, to count objects.
8842 (total_conses, total_markers, total_symbols, total_vector_size)
8843 (total_free_conses, total_free_markers, total_free_symbols)
8844 (total_free_floats, total_floats, total_free_intervals)
8845 (total_intervals, total_strings, total_free_strings):
8846 Now EMACS_INT, not int. All uses changed.
8847 (Fgarbage_collect): Compute overall total using a double, so that
8848 integer overflow is less likely to be a problem. Check for overflow
8849 when converting back to an integer.
8850 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
8851 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
8852 These were 'int' variables that could overflow on 64-bit hosts;
8853 they were never used, so remove them instead of repairing them.
8854 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
8855 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
8856 Previously, this ceilinged at INT_MAX, but that doesn't work on
8857 64-bit machines.
8858 (allocate_pseudovector): Don't use EMACS_INT when int would do.
8860 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
8861 (allocate_vectorlike): Check for ptrdiff_t overflow.
8862 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
8863 when a (possibly-narrower) signed value would do just as well.
8864 We prefer using signed arithmetic, to avoid comparison confusion.
8866 * alloc.c: Catch some string size overflows that we were missing.
8867 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
8868 for convenience in STRING_BYTES_MAX.
8869 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
8870 The definition here is exact; the one in lisp.h was approximate.
8871 (allocate_string_data): Check for string overflow. This catches
8872 some instances we weren't catching before. Also, it catches
8873 size_t overflow on (unusual) hosts where SIZE_MAX <= min
8874 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
8875 and ptrdiff_t and EMACS_INT are both 64 bits.
8877 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
8878 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
8879 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
8881 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
8883 * alloc.c (Fmake_string): Check for out-of-range init.
8885 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
8887 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
8889 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
8891 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
8892 xg_get_default_scrollbar_width.
8894 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
8895 (int_gtk_range_get_value): Move to the scroll bar part of the file.
8896 (style_changed_cb): Call update_theme_scrollbar_width and call
8897 x_set_scroll_bar_default_width and xg_frame_set_char_size for
8898 all frames (Bug#8505).
8899 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
8900 Call gtk_window_set_resizable if HAVE_GTK3.
8901 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
8902 and height if HAVE_GTK3 (Bug#8505).
8903 (scroll_bar_width_for_theme): New variable.
8904 (update_theme_scrollbar_width): New function.
8905 (xg_get_default_scrollbar_width): Move code to
8906 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
8907 (xg_initialize): Call update_theme_scrollbar_width.
8909 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
8911 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
8913 2011-06-12 Martin Rudalics <rudalics@gmx.at>
8915 * frame.c (make_frame): Call other_buffer_safely instead of
8916 other_buffer.
8918 * window.c (temp_output_buffer_show): Call display_buffer with
8919 second argument Vtemp_buffer_show_specifiers and reset latter
8920 immediately after the call.
8921 (Vtemp_buffer_show_specifiers): New variable.
8922 (auto_window_vscroll_p, next_screen_context_lines)
8923 (Vscroll_preserve_screen_position): Remove leading asterisks from
8924 doc-strings.
8926 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
8928 Fix minor problems found by GCC 4.6.0 static checking.
8929 * buffer.c (Qclone_number): Remove for now, as it's unused.
8930 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
8931 (record_buffer): Remove unused local.
8932 * frame.c (other_visible_frames, frame_buffer_list): Now static.
8933 (set_frame_buffer_list): Remove; unused.
8934 * frame.h (other_visible_frames): Remove decl.
8935 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
8936 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
8937 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
8938 if HAVE_GPM.
8939 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
8940 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):

9417 New error handlers.
9418 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
9419 Obey Vx_select_enable_clipboard_manager. Catch errors in
9420 x_clipboard_manager_save (Bug#8779).
9421 (Vx_select_enable_clipboard_manager): New variable.
9422 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
9424 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
9426 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
9428 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9430 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
9431 in the current matrix if keep_current_p is non-zero.
9433 2011-06-04 Eli Zaretskii <eliz@gnu.org>
9435 * bidi.c (bidi_level_of_next_char): Fix last change.

9442 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
9443 (bidi_cache_search, bidi_cache_iterator_state)
9444 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9445 (bidi_level_of_next_char, bidi_move_to_visually_next):
9446 Support character positions inside a run of characters covered by a
9447 display string.
9448 (bidi_paragraph_init, bidi_resolve_explicit_1)
9449 (bidi_level_of_next_char): Call bidi_fetch_char and
9450 bidi_fetch_char_advance instead of FETCH_CHAR and
9451 FETCH_CHAR_ADVANCE.
9452 (bidi_init_it): Initialize new members.
9453 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
9454 definitions.
9455 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
9456 instead of using explicit *_CHAR codes.
9457 (bidi_resolve_explicit, bidi_resolve_weak):
9458 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
9459 bidirectional text is supported only in multibyte buffers.
9460 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
9461 it to initialize the frame_window_p member of struct bidi_it.
9462 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
9463 (bidi_resolve_explicit, bidi_resolve_weak)
9464 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
9465 bidi_it->nchars is non-positive.
9466 (bidi_level_of_next_char): Don't try to lookup the cache for the
9467 next/previous character if nothing is cached there yet, or if we
9468 were just reseat()'ed to a new position.
9470 * xdisp.c (set_cursor_from_row): Set start and stop points
9471 according to the row's direction when priming the loop that looks
9472 for the glyph on which to display cursor.
9473 (single_display_spec_intangible_p): Function deleted.
9474 (display_prop_intangible_p): Reimplement to call
9475 handle_display_spec instead of single_display_spec_intangible_p.
9476 Accept 3 additional arguments needed by handle_display_spec.
9477 This fixes incorrect cursor motion across display property with complex
9478 values: lists, `(when COND...)' forms, etc.
9479 (single_display_spec_string_p): Support property values that are
9480 lists with the argument STRING its top-level element.
9481 (display_prop_string_p): Fix the condition for processing a
9482 property that is a list to be consistent with handle_display_spec.

9484 last portion of handle_display_prop.
9485 (compute_display_string_pos): Accept additional argument
9486 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
9487 value of a `display' property is a "replacing spec".
9488 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
9489 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
9490 the display property, but just return a value indicating whether
9491 the display property will replace the characters it covers.
9492 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
9493 frame_window_p members of struct bidi_it.
9494 (compute_display_string_pos, compute_display_string_end):
9495 New functions.
9496 (push_it): Accept second argument POSITION, where pop_it should
9497 jump to continue iteration.
9498 (reseat_1): Initialize bidi_it.disp_pos.

9501 display_prop_intangible_p to its new signature.
9503 * dispextern.h (struct bidi_it): New member frame_window_p.
9504 (bidi_init_it): Update prototypes.
9505 (display_prop_intangible_p): Update prototype.
9506 (compute_display_string_pos, compute_display_string_end):
9507 Declare prototypes.

9515 * lisp.h: Change signatures accordingly.
9516 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
9517 All callers changed. (Bug#8762)
9519 * gnutls.c: Use Emacs's memory allocators.
9520 Without this change, the gnutls library would invoke malloc etc.
9521 directly, which causes problems on non-SYNC_INPUT hosts, and which
9522 runs afoul of improving memory_full behavior. (Bug#8761)
9523 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
9524 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
9525 xfree instead of the default malloc, realloc, free.
9526 (Fgnutls_boot): No need to check for memory allocation failure,
9527 since xmalloc does that for us.
9529 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
9530 * category.c (hash_get_category_set):
9531 * ccl.c (ccl_driver):
9532 * charset.c (Fdefine_charset_internal):

9540 (hashfn_equal, hashfn_user_defined, make_hash_table)
9541 (maybe_resize_hash_table, hash_lookup, hash_put)
9542 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
9543 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
9544 (Fsxhash, Fgethash, Fputhash, Fmaphash):
9545 * image.c (make_image, search_image_cache, lookup_image)
9546 (xpm_put_color_table_h):
9547 * lisp.h (struct Lisp_Hash_Table):
9548 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
9549 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
9550 for hashes and hash indexes, instead of 'unsigned' and 'int'.
9551 * alloc.c (allocate_vectorlike):
9552 Check for overflow in vector size calculations.
9553 * ccl.c (ccl_driver):
9554 Check for overflow when converting EMACS_INT to int.
9555 * fns.c, image.c: Remove unnecessary static decls that would otherwise
9556 need to be updated by these changes.
9557 * fns.c (make_hash_table, maybe_resize_hash_table):
9558 Check for integer overflow with large hash tables.
9559 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
9560 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
9561 (SXHASH_REDUCE): New macro.
9562 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
9563 Use it instead of discarding useful hash info with large hash values.
9564 (sxhash_float): New function.
9565 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
9566 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
9567 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
9568 Rewrite to use FIXNUM_BITS, as this simplifies things.
9569 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
9570 Adjust signatures to match updated version of code.
9571 (consing_since_gc): Now EMACS_INT, since a single hash table can
9572 use more than INT_MAX bytes.
9574 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
9576 Make it possible to build with GCC-4.6+ -O2 -flto.
9578 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
9580 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
9582 * minibuf.c (get_minibuffer, read_minibuf_unwind):
9583 Call minibuffer-inactive-mode.
9585 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
9587 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
9588 Update dependencies.
9590 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9592 * data.c (init_data): Remove code for UTS, this system is not
9593 supported anymore.
9595 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9597 Don't force ./temacs to start in terminal mode.
9599 * frame.c (make_initial_frame): Initialize faces in all cases, not
9600 only when CANNOT_DUMP is defined.
9601 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
9603 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9605 * dispnew.c (add_window_display_history): Use const for the string
9606 pointer. Remove declaration, not needed.
9608 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9610 Use 'inline', not 'INLINE'.
9611 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
9612 * alloc.c, fontset.c (INLINE): Remove.
9613 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
9614 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
9615 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
9616 * gmalloc.c (register_heapinfo): Use inline unconditionally.
9617 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
9619 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9621 Make it possible to run ./temacs.
9623 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
9624 syms_of_callproc does the same thing. Remove test for
9625 "initialized", do it in the caller.
9626 * emacs.c (main): Avoid calling set_initial_environment when dumping.
9628 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
9630 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
9631 (read_minibuf): Use get_minibuffer.
9632 (syms_of_minibuf): Use DEFSYM.
9633 (Qmetadata): New var.
9634 * data.c (Qbuffer): Don't make it static.
9635 (syms_of_data): Use DEFSYM.
9637 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9639 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
9640 (CCL_CODE_MIN): New macro.
9642 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
9644 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
9646 * eval.c (Qdebug): Now static.
9647 * lisp.h (Qdebug): Remove decl. This reverts a part of the
9648 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
9649 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
9651 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9653 * image.c: Various fixes to ImageMagick code comments.
9654 (Fimagemagick_types): Doc fix.
9656 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
9658 Minor fixes prompted by GCC 4.6.0 warnings.
9660 * xselect.c (converted_selections, conversion_fail_tag): Now static.
9662 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
9663 (x_clipboard_manager_save_all): Move extern decl to ...
9664 * xterm.h: ... here, so that it can be checked for consistency.
9666 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9668 * xselect.c (x_clipboard_manager_save_frame)
9669 (x_clipboard_manager_save_all): New functions.
9670 (Fx_clipboard_manager_save): Lisp function deleted.
9672 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
9673 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
9675 * xterm.h: Update prototype.
9677 2011-05-28 William Xu <william.xwl@gmail.com>
9679 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
9680 exiting (Bug#8239).
9682 2011-05-28 Jim Meyering <meyering@redhat.com>
9684 Avoid a sign-extension bug in crypto_hash_function.
9685 * fns.c (to_uchar): Define.
9686 (crypto_hash_function): Use it to convert some newly-signed
9687 variables to unsigned, to avoid sign-extension bugs. For example,
9688 without this change, (md5 "truc") would evaluate to
9689 45723a2aff78ff4fff7fff1114760e62 rather than the expected
9690 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
9691 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
9693 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9695 Integer overflow fixes.
9697 * dbusbind.c: Serial number integer overflow fixes.
9698 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
9699 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
9700 to hold a serial number that is too large for a fixnum.
9701 (Fdbus_method_return_internal, Fdbus_method_error_internal):
9702 Check for serial numbers out of range. Decode any serial number
9703 that was so large that it became a float. (Bug#8722)
9705 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
9706 (Fdbus_call_method, Fdbus_call_method_asynchronously):
9707 Use XFASTINT rather than XUINT when numbers are nonnegative.
9708 (xd_append_arg, Fdbus_method_return_internal):
9709 (Fdbus_method_error_internal): Likewise. Also, for unsigned
9710 arguments, check that Lisp number is nonnegative, rather than
9711 silently wrapping negative numbers around. (Bug#8722)
9712 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
9713 (Bug#8722)
9715 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
9717 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
9719 ccl: Add integer overflow checks.
9720 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
9721 (IN_INT_RANGE): New macros.
9722 (ccl_driver): Use them to check for integer overflow when
9723 decoding a CCL program. Many of the new checks are whether XINT (x)
9724 fits in int; it doesn't always, on 64-bit hosts. The new version
9725 doesn't catch all possible integer overflows, but it's an
9726 improvement. (Bug#8719)
9728 * alloc.c (make_event_array): Use XINT, not XUINT.
9729 There's no need for unsigned here.
9731 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
9732 This follows up to the 2011-05-06 change that substituted uintptr_t
9733 for EMACS_INT. This case wasn't caught back then.
9735 Rework Fformat to avoid integer overflow issues.
9736 * editfns.c: Include <float.h> unconditionally, as it's everywhere
9737 now (part of C89). Include <verify.h>.
9738 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
9739 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
9740 (Fformat): Avoid the prepass trying to compute sizes; it was only
9741 approximate and thus did not catch overflow reliably. Instead, walk
9742 through the format just once, formatting and computing sizes as we go,
9743 checking for integer overflow at every step, and allocating a larger
9744 buffer as needed. Keep track separately whether the format is
9745 multibyte. Keep only the most-recently calculated precision, rather
9746 than them all. Record whether each argument has been converted to
9747 string. Use EMACS_INT, not int, for byte and char and arg counts.
9748 Support field widths and precisions larger than INT_MAX. Avoid
9749 sprintf's undefined behavior with conversion specifications such as %#d
9750 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
9751 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
9752 formatting out-of-range floating point numbers with int
9753 formats. (Bug#8668)
9755 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
9757 * data.c: Avoid integer truncation in expressions involving floats.
9758 * data.c: Include <intprops.h>.
9759 (arith_driver): When there's an integer overflow in an expression
9760 involving floating point, convert the integers to floating point
9761 so that the resulting value does not suffer from catastrophic
9762 integer truncation. For example, on a 64-bit host (* 4
9763 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
9764 Do not rely on undefined behavior after integer overflow.
9766 merge count_size_as_multibyte, parse_str_to_multibyte
9767 * character.c, character.h (count_size_as_multibyte):
9768 Rename from parse_str_to_multibyte; all uses changed.
9769 Check for integer overflow.
9770 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
9771 since it's now a duplicate of the other. This is more of
9772 a character than a buffer op, so better that it's in character.c.
9773 * fns.c, print.c: Adjust to above changes.
9775 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
9777 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
9779 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9781 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9782 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
9783 (x_clipboard_manager_save): Now static.
9784 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
9786 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9787 (crypto_hash_function): Now static.
9788 Fix pointer signedness problems. Avoid unnecessary initializations.
9790 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
9792 * termhooks.h (Vselection_alist): Make it terminal-local.
9794 * terminal.c (create_terminal): Initialize it.
9796 * xselect.c: Support for clipboard managers.
9797 (Vselection_alist): Move to termhooks.h as terminal-local var.
9798 (LOCAL_SELECTION): New macro.
9799 (x_atom_to_symbol): Handle x_display_info_for_display fail case.

9801 (x_handle_selection_request, lisp_data_to_selection_data)
9802 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
9803 (x_own_selection, x_get_local_selection, x_convert_selection):
9804 New arg, specifying work frame. Use terminal-local Vselection_alist.
9805 (some_frame_on_display): Delete unused function.
9806 (Fx_own_selection_internal, Fx_get_selection_internal)
9807 (Fx_disown_selection_internal, Fx_selection_owner_p)
9808 (Fx_selection_exists_p): New optional frame arg.
9809 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
9810 (x_handle_selection_clear): Don't treat other terminals with the
9811 same keyboard specially. Use the terminal-local Vselection_alist.
9812 (x_clear_frame_selections): Use Frun_hook_with_args.
9814 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
9816 * xterm.h: Add support for those atoms.
9818 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
9820 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
9821 (converted_selections, conversion_fail_tag): New global variables.
9822 (x_selection_request_lisp_error): Free the above.
9823 (x_get_local_selection): Remove unnecessary code.
9824 (x_reply_selection_request): Args changed; handle arbitrary array
9825 of converted selections stored in converted_selections.
9826 Separate the XChangeProperty and SelectionNotify steps.
9827 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
9828 (x_convert_selection): New function.
9829 (x_handle_selection_event): Simplify.
9830 (x_get_foreign_selection): Don't ignore incoming requests while
9831 waiting for an answer; this will fail when we implement
9832 SAVE_TARGETS, and seems unnecessary anyway.
9833 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
9834 (Vx_sent_selection_functions): Doc fix.
9836 2011-05-26 Leo Liu <sdl.web@gmail.com>
9838 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
9840 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9842 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
9844 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
9845 for fringe update if it has periodic bitmap.
9846 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
9847 and fringe_bitmap_periodic_p.
9849 * fringe.c (get_fringe_bitmap_data): New function.
9850 (draw_fringe_bitmap_1, update_window_fringes): Use it.
9851 (update_window_fringes): Record periodicity of fringe bitmap in glyph
9852 row. Mark glyph row for fringe update if periodicity changed.
9854 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
9855 for fringe update unless it has periodic bitmap.
9857 2011-05-25 Kenichi Handa <handa@m17n.org>
9859 * xdisp.c (get_next_display_element): Set correct it->face_id for
9860 a static composition.
9862 2011-05-24 Leo Liu <sdl.web@gmail.com>
9864 * deps.mk (fns.o):
9865 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
9867 * fns.c (crypto_hash_function, Fsha1): New function.
9868 (Fmd5): Use crypto_hash_function.
9869 (syms_of_fns): Add Ssha1.
9871 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
9873 * gnutls.c: Remove unused macros.
9874 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
9875 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
9876 Remove macros that are defined and never used.
9877 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
9879 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
9881 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
9882 (Fx_get_selection_internal): Minor cleanup.
9883 (Fx_own_selection_internal): Rename arguments for consistency with
9884 select.el.
9886 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
9888 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
9890 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
9892 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
9894 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9896 * dispnew.c (scrolling_window): Don't exclude the case that the
9897 last enabled row in the desired matrix touches the bottom boundary.
9899 2011-05-21 Glenn Morris <rgm@gnu.org>
9901 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
9902 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
9903 and add some more files.
9905 2011-05-20 Eli Zaretskii <eliz@gnu.org>
9907 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
9908 report_file_error introduced by the change from 2011-05-07.
9910 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
9912 * systime.h (Time): Define only if emacs is defined.
9913 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
9914 where the include path doesn't have X11/X.h by default. See
9915 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
9917 2011-05-20 Kenichi Handa <handa@m17n.org>
9919 * composite.c (find_automatic_composition): Fix previous change.
9921 2011-05-20 Glenn Morris <rgm@gnu.org>
9923 * lisp.mk: New file, split from Makefile.in.
9924 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
9925 (shortlisp): Remove.
9926 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
9928 2011-05-19 Glenn Morris <rgm@gnu.org>
9930 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
9931 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
9932 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
9933 (lisp): Set the order to that of loadup.el.
9934 (shortlisp): Make it a copy of $lisp.
9935 (SOME_MACHINE_LISP): Remove.
9936 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
9937 Use just $shortlisp, not $SOME_MACHINE_LISP too.
9939 2011-05-18 Kenichi Handa <handa@m17n.org>
9941 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
9942 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
9943 (find_automatic_composition): Mostly rewrite for efficiency.
9945 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
9947 * makefile.w32-in: Update dependencies.
9949 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
9951 * menu.c: Include limits.h (fixes the MS-Windows build broken by
9952 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
9954 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
9956 Fix some integer overflow issues, such as string length overflow.
9958 * insdel.c (count_size_as_multibyte): Check for string overflow.
9960 * character.c (lisp_string_width): Check for string overflow.
9961 Use EMACS_INT, not int, for string indexes and lengths; in
9962 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
9963 the resulting string length overflows an EMACS_INT; instead,
9964 report a string overflow if no precision given. When checking for
9965 precision exhaustion, use a check that cannot possibly have
9966 integer overflow. (Bug#8675)
9967 * character.h (lisp_string_width): Adjust to new signature.
9969 * alloc.c (string_overflow): New function.
9970 (Fmake_string): Use it. This doesn't change behavior, but saves
9971 a few bytes and will simplify future changes.
9972 * character.c (string_escape_byte8): Likewise.
9973 * lisp.h (string_overflow): New decl.
9975 Fixups, following up to the user-interface timestamp change.
9976 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
9977 for UI timestamps, instead of unsigned long.
9978 * msdos.c (mouse_get_pos): Likewise.
9979 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
9980 * w32gui.h (Time): Define by including "systime.h" rather than by
9981 declaring it ourselves. (Bug#8664)
9983 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
9984 * image.c (clear_image_cache): Likewise.
9986 * term.c (term_mouse_position): Don't assume time_t wraparound.
9988 Be more systematic about user-interface timestamps.
9989 Before, the code sometimes used 'Time', sometimes 'unsigned long',
9990 and sometimes 'EMACS_UINT', to represent these timestamps.
9991 This change causes it to use 'Time' uniformly, as that's what X uses.
9992 This makes the code easier to follow, and makes it easier to catch
9993 integer overflow bugs such as Bug#8664.
9994 * frame.c (Fmouse_position, Fmouse_pixel_position):
9995 Use Time, not unsigned long, for user-interface timestamps.
9996 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
9997 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
9998 * keyboard.h (last_event_timestamp): Likewise.
9999 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10000 * menu.h (xmenu_show): Likewise.
10001 * term.c (term_mouse_position): Likewise.
10002 * termhooks.h (struct input_event.timestamp): Likewise.
10003 (struct terminal.mouse_position_hook): Likewise.
10004 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10005 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10006 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10007 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10008 what it was before.
10009 * menu.h, termhooks.h: Include "systime.h", for Time.
10011 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10012 Don't assume that the difference between two unsigned long values
10013 can fit into an integer. At this point, we know button_down_time
10014 <= event->timestamp, so the difference must be nonnegative, so
10015 there's no need to cast the result if double-click-time is
10016 nonnegative, as it should be; check that it's nonnegative, just in
10017 case. This bug is triggered when events are more than 2**31 ms
10018 apart (about 25 days). (Bug#8664)
10020 * xselect.c (last_event_timestamp): Remove duplicate decl.
10021 (x_own_selection): Remove needless cast to unsigned long.
10023 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10024 that always fit in int. Use a sentinel instead of a counter, to
10025 avoid a temp and to allay GCC's concerns about possible int overflow.
10026 * frame.h (struct frame): Use int for menu_bar_items_used
10027 instead of EMACS_INT, since it always fits in int.
10029 * menu.c (grow_menu_items): Check for int overflow.
10031 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10033 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10034 Before, the code was not consistent. These values cannot exceed
10035 2**31 - 1 so there's no need to make them unsigned.
10036 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10037 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10038 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10039 as modifiers.
10040 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10042 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10043 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10044 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10045 presumably because the widths might not match.
10047 * window.c (size_window): Avoid needless test at loop start.
10049 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10051 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10053 2011-05-12 Drew Adams <drew.adams@oracle.com>
10055 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10057 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10059 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10060 `width' to `bar_area_x' and `bar_area_width', respectively.
10061 (x_scroll_run): Take account of fringe background extension.
10063 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10064 Rename local vars `left' and `width' to `bar_area_x' and
10065 `bar_area_width', respectively.
10066 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10067 background extension.
10069 2011-05-10 Jim Meyering <meyering@redhat.com>
10071 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10073 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10075 * image.c (Finit_image_library): Return t for built-in image types,
10076 like pbm and xbm. (Bug#8640)
10078 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10080 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10082 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10084 * w32console.c (Fset_screen_color): Doc fix.
10085 (Fget_screen_color): New function.
10086 (syms_of_ntterm): Defsubr it.
10088 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10089 unlink the temporary file if Fcall_process didn't create it in the
10090 first place.
10091 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10092 child process will be redirected to a file specified with `:file'.
10093 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10094 cue to call_process_cleanup not to close that handle.
10096 2011-05-07 Ben Key <bkey76@gmail.com>
10098 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10099 one of two shell specific rules, either bootstrap-temacs-CMD or
10100 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10101 to the previous implementation of the bootstrap-temacs rule.
10102 The bootstrap-temacs-CMD rule is similar to the previous
10103 implementation of the bootstrap-temacs rule except that it
10104 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10105 variable.
10107 These changes, along with some changes to nt/configure.bat,
10108 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10109 earlier fix to add support for --cflags and --ldflags options
10110 that include quotes so that it works whether make uses cmd or
10111 sh as the shell.
10113 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10115 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10116 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10117 is a constant.
10118 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10119 a string. Handle both cases.
10120 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10121 (Fdbus_register_method): Use Qinvalid_function.
10123 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10125 * makefile.w32-in: Update dependencies.
10126 (LISP_H): Add inttypes.h and stdin.h.
10127 (PROCESS_H): Add unistd.h.
10129 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10131 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10132 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10134 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10136 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10138 * term.c (vfatal): Remove stray call to va_end.
10139 It's not needed and the C Standard doesn't allow it here anyway.
10141 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10142 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10144 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10145 bytes.
10147 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10149 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10151 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10153 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10155 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10157 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10158 * charset.c (Fdefine_charset_internal): Don't initialize
10159 charset.code_space[15]. The value was garbage, on hosts with
10160 32-bit int (Bug#8600).
10162 * lread.c (read_integer): Be more consistent with string-to-number.
10163 Use string_to_number to do the actual conversion; this avoids
10164 rounding errors and fixes some other screwups. Without this fix,
10165 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10166 (digit_to_number): Move earlier, for benefit of read_integer.
10167 Return -1 if the digit is out of range for the base, -2 if it is
10168 not a digit in any supported base. (Bug#8602)
10170 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10172 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10173 to match comment at start of function. This also removes a
10174 GCC warning about overflow in a 32+64-bit port.
10176 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10178 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10179 Reported by Stefan Monnier in
10180 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10181 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10182 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10184 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10185 (EMACS_UINTPTR): Likewise, with uintptr_t.
10187 * lisp.h: Prefer 64-bit EMACS_INT if available.
10188 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10189 on 32-bit hosts that have 64-bit int, so that they can access
10190 large files.
10191 However, temporarily disable this change unless the temporary
10192 symbol WIDE_EMACS_INT is defined.
10194 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10196 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10197 This removes an assumption that EMACS_INT and long are the same
10198 width as pointers. The assumption is true for Emacs porting targets
10199 now, but we want to make other targets possible.
10200 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10201 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10202 In the rest of the code, change types of integers that hold casted
10203 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10204 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10205 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10206 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10207 No need to cast type when ORing.
10208 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10209 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10210 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10211 assume EMACS_INT is the same width as char *.
10212 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10213 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10214 Remove no-longer-needed casts.
10215 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10216 (xg_tool_bar_help_callback, xg_make_tool_item):
10217 Use EMACS_INTPTR to hold an integer
10218 that will be cast to void *; this can avoid a GCC warning
10219 if EMACS_INT is not the same width as void *.
10220 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10221 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10222 (current_message_1, set_message_1):
10223 Use a local to convert to proper width without a cast.
10224 * xmenu.c (dialog_selection_callback): Likewise.
10226 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10227 Also, don't assume VALBITS / RAND_BITS is less than 5,
10228 and don't rely on undefined behavior when shifting a 1 left into
10229 the sign bit.
10230 * lisp.h (get_random): Change signature to match.
10232 * lread.c (hash_string): Use size_t, not int, for hash computation.
10233 Normally we prefer signed values; but hashing is special, because
10234 it's better to use unsigned division on hash table sizes so that
10235 the remainder is nonnegative. Also, size_t is the natural width
10236 for hashing into memory. The previous code used 'int', which doesn't
10237 retain enough info to hash well into very large tables.
10238 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10240 * dbusbind.c: Don't possibly lose pointer info when converting.
10241 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10242 Use XPNTR rather than XHASH, so that the high-order bits of
10243 the pointer aren't lost when converting through void *.
10245 * eval.c (Fautoload): Don't double-shift a pointer.
10247 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10249 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10251 * gnutls.c (DEF_GNUTLS_FN):
10252 * image.c (DEF_IMGLIB_FN): Make function pointers static.
10254 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
10256 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
10257 marker. (Bug#8610)
10259 2011-05-05 Eli Zaretskii <eliz@gnu.org>
10261 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:

10330 * process.c: Include lisp.h before w32.h, not after.
10331 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10332 instead of gnutls_record_check_pending.
10334 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10336 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10338 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
10339 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
10340 as passed in.
10342 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
10344 * xterm.c (x_set_frame_alpha): Do not set property on anything
10345 else than FRAME_X_OUTER_WINDOW (Bug#8608).
10347 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10349 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)

10383 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
10384 rather than `XVECTOR (FOO)->size'.
10386 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10387 inttypes.h, as a gnulib replacement is used if it not available in
10388 system headers.
10390 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10392 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
10393 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
10394 of MOST_POSITIVE_FIXNUM. (Bug#8528)
10396 * coding.c (coding_alloc_by_realloc): Error out if destination
10397 will grow beyond MOST_POSITIVE_FIXNUM.
10398 (decode_coding_emacs_mule): Abort if there isn't enough place in
10399 charbuf for the composition carryover bytes. Reserve an extra
10400 space for up to 2 characters produced in a loop.
10401 (decode_coding_iso_2022): Abort if there isn't enough place in
10402 charbuf for the composition carryover bytes.
10404 2011-04-21 Eli Zaretskii <eliz@gnu.org>

10407 aborting when %lld or %lll format is passed.
10408 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
10409 %llo or %llx format is passed. (Bug#8545)
10411 * window.c (window_scroll_line_based): Use a marker instead of
10412 simple variables to record original value of point. (Bug#7952)
10414 * doprnt.c (doprnt): Fix the case where a multibyte sequence
10415 produced by %s or %c overflows available buffer space. (Bug#8545)
10417 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10419 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
10420 (SIZE_MAX): Move defn after all includes, as they might #define it.
10422 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10424 * w32.c (init_environment): Warn about defaulting HOME to C:\.
10426 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10428 * keyboard.c (Qdelayed_warnings_hook): Define.
10429 (command_loop_1): Run `delayed-warnings-hook'
10430 if Vdelayed_warnings_list is non-nil.
10431 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
10432 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
10434 2011-04-28 Eli Zaretskii <eliz@gnu.org>
10436 * doprnt.c (doprnt): Don't return value smaller than the buffer
10437 size if the message was truncated. (Bug#8545).
10439 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10441 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
10442 (Fx_window_property): #if-0 the whole functions, not just the bodies.
10444 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10446 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
10448 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
10450 * makefile.w32-in: Update dependencies.
10452 2011-04-27 Eli Zaretskii <eliz@gnu.org>
10454 Improve `doprnt' and its usage. (Bug#8545)
10455 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
10456 `format_end'. Remove support for %l as a conversion specifier.
10457 Don't use xrealloc. Improve diagnostics when the %l size modifier
10458 is used. Update the commentary.
10460 * eval.c (verror): Simplify calculation of size_t.
10462 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
10463 messages.
10465 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
10467 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10468 change.
10470 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10472 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10473 This makes this file independent of the recent pseudovector change.
10475 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
10477 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10479 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10480 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10481 Remove unused local.
10482 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10484 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
10485 GCC 4.6.0 optimizes based on type-based alias analysis.
10486 For example, if b is of type struct buffer * and v of type struct
10487 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10488 != &v->size, and therefore "v->size = 1; b->size = 2; return
10489 v->size;" must therefore return 1. This assumption is incorrect
10490 for Emacs, since it type-puns struct Lisp_Vector * with many other
10491 types. To fix this problem, this patch adds a new type struct
10492 vectorlike_header that documents the constraints on layout of vectors
10493 and pseudovectors, and helps optimizing compilers not get fooled
10494 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
10495 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10496 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10497 the size member.
10498 (XSETPVECTYPE): Rewrite in terms of new macro.
10499 (XSETPVECTYPESIZE): New macro, specifying both type and size.
10500 This is a bit clearer, and further avoids the possibility of
10501 undesirable aliasing.
10502 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10503 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10504 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10505 since Lisp_Subr is a special case (no "next" field).
10506 (ASIZE): Now uses header.size rather than size.
10507 All previous uses of XVECTOR (foo)->size replaced to use this macro,
10508 to avoid the hassle of writing XVECTOR (foo)->header.size.
10509 (struct vectorlike_header): New type.
10510 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10511 object, to help avoid aliasing.
10512 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10513 (SUBRP): Likewise, since Lisp_Subr is a special case.
10514 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10515 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10516 (struct Lisp_Hash_Table): Combine first two members into a single
10517 struct vectorlike_header member. All uses of "size" and "next" members
10518 changed to be "header.size" and "header.next".
10519 * buffer.h (struct buffer): Likewise.
10520 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
10521 * frame.h (struct frame): Likewise.
10522 * process.h (struct Lisp_Process): Likewise.
10523 * termhooks.h (struct terminal): Likewise.
10524 * window.c (struct save_window_data, struct saved_window): Likewise.
10525 * window.h (struct window): Likewise.
10526 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
10527 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
10528 * buffer.c (init_buffer_once): Likewise.
10529 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
10530 special case.
10531 * process.c (Fformat_network_address): Use local var for size,
10532 for brevity.
10534 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
10536 Make the Lisp reader and string-to-float more consistent (Bug#8525)
10537 * data.c (atof): Remove decl; no longer used or needed.
10538 (digit_to_number): Move to lread.c.
10539 (Fstring_to_number): Use new string_to_number function, to be
10540 consistent with how the Lisp reader treats infinities and NaNs.
10541 Do not assume that floating-point numbers represent EMACS_INT
10542 without losing information; this is not true on most 64-bit hosts.
10543 Avoid double-rounding errors, by insisting on integers when
10544 parsing non-base-10 numbers, as the documentation specifies.
10545 * lisp.h (string_to_number): New decl, replacing ...
10546 (isfloat_string): Remove.
10547 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
10548 (read1): Do not accept +. and -. as integers; this
10549 appears to have been a coding error. Similarly, do not accept
10550 strings like +-1e0 as floating point numbers. Do not report
10551 overflow for integer overflows unless the base is not 10 which
10552 means we have no simple and reliable way to continue.
10553 Break out the floating-point parsing into a new
10554 function string_to_number, so that Fstring_to_number parses
10555 floating point numbers consistently with the Lisp reader.
10556 (digit_to_number): Move here from data.c. Make it static inline.
10557 (E_CHAR, EXP_INT): Remove, replacing with ...
10558 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
10559 (string_to_number): New function, replacing isfloat_string.
10560 This function checks for valid syntax and produces the resulting
10561 Lisp float number too. Rework it so that string-to-number
10562 no longer mishandles examples like "1.0e+". Use strtoumax,
10563 so that overflow for non-base-10 numbers is reported only when
10564 there's no portable and simple way to convert to floating point.
10566 * textprop.c (set_text_properties_1): Rewrite for clarity,
10567 and to avoid GCC warning about integer overflow.
10569 * intervals.h (struct interval): Use EMACS_INT for members
10570 where EMACS_UINT might cause problems. See
10571 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
10572 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
10573 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
10574 All uses changed.
10575 (offset_intervals): Tell GCC not to worry about length overflow
10576 when negating a negative length.
10578 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
10579 (overrun_check_free): Likewise.
10581 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
10582 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
10583 word size.
10585 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10586 (gnutls_make_error): Rename local to avoid shadowing.
10587 (gnutls_emacs_global_deinit): ifdef out; not used.
10588 (Fgnutls_boot): Use const for pointer to readonly storage.
10589 Comment out unused local. Fix pointer signedness problems.
10591 * lread.c (openp): Don't stuff size_t into an 'int'.
10592 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
10593 about possible signed overflow.
10595 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10596 (GDK_KEY_g): Don't define if already defined.
10597 (xg_prepare_tooltip): Avoid pointer signedness problem.
10598 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
10600 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
10601 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
10603 * xfns.c (Fx_window_property): Simplify a bit,
10604 to make a bit faster and to avoid GCC 4.6.0 warning.
10605 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
10607 * fns.c (internal_equal): Don't assume size_t fits in int.
10609 * alloc.c (compact_small_strings): Tighten assertion a little.
10611 Replace pEd with more-general pI, and fix some printf arg casts.
10612 * lisp.h (pI): New macro, generalizing old pEd macro to other
10613 conversion specifiers. For example, use "...%"pI"d..." rather
10614 than "...%"pEd"...".
10615 (pEd): Remove. All uses replaced with similar uses of pI.
10616 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
10617 * alloc.c (check_pure_size): Don't overflow by converting size to int.
10618 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
10619 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
10620 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
10621 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
10622 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
10623 64-bit hosts.
10624 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
10625 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
10626 * print.c (safe_debug_print, print_object): Likewise.
10627 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
10628 to int.
10629 Use pI instead of if-then-else-abort. Use %p to avoid casts,
10630 avoiding the 0 flag, which is not portable.
10631 * process.c (Fmake_network_process): Use pI to avoid cast.
10632 * region-cache.c (pp_cache): Likewise.
10633 * xdisp.c (decode_mode_spec): Likewise.
10634 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
10635 behavior on 64-bit hosts with printf arg.
10636 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
10637 (x_stop_queuing_selection_requests): Likewise.
10638 (x_get_window_property): Don't truncate byte count to an 'int'
10639 when tracing.
10641 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
10642 here, since it parses constructs like leading '-' and spaces,
10643 which are not wanted; and it overflows with large numbers.
10644 Instead, simply match F[0-9]+, which is what is wanted anyway.
10646 * alloc.c: Remove unportable assumptions about struct layout.
10647 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
10648 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
10649 (allocate_vectorlike, make_pure_vector): Use the new macros,
10650 plus offsetof, to remove unportable assumptions about struct layout.
10651 These assumptions hold on all porting targets that I know of, but
10652 they are not guaranteed, they're easy to remove, and removing them
10653 makes further changes easier.
10655 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
10656 This doesn't fix a bug but makes the code clearer.
10657 (string_overrun_cookie): Now const. Use initializers that
10658 don't formally overflow signed char, to avoid warnings.
10659 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
10660 can cause Emacs to crash when string overrun checking is enabled.
10661 (allocate_buffer): Don't assume sizeof (struct buffer) is a
10662 multiple of sizeof (EMACS_INT); it need not be, if
10663 alignof(EMACS_INT) < sizeof (EMACS_INT).
10664 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
10666 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

11532 * fileio.c (a_write, e_write): Modify declaration of arguments and
11533 local variables to support buffers larger than 2GB.
11534 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
11536 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
11537 argument, local variables, and return value.
11539 * lisp.h: Update prototypes of emacs_write and emacs_read.
11541 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
11543 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
11545 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
11547 Fix more problems found by GCC 4.6.0's static checks.
11549 * xdisp.c (vmessage): Use a better test for character truncation.
11551 * charset.c (load_charset_map): <, not <=, for optimization,
11552 and to avoid potential problems with integer overflow.
11553 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
11554 * casetab.c (set_identity, shuffle): Likewise.
11555 * editfns.c (Fformat): Likewise.
11556 * syntax.c (skip_chars): Likewise.
11558 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
11559 This also lets GCC 4.6.0 generate slightly better loop code.
11561 * callint.c (Fcall_interactively): <, not <=, for optimization.
11562 (Fcall_interactively): Count the number of arguments produced,
11563 not the number of arguments given. This is simpler and lets GCC
11564 4.6.0 generate slightly better code.
11566 * ftfont.c: Distingish more carefully between FcChar8 and char.
11567 The previous code passed unsigned char * to a functions like
11568 strlen and xstrcasecmp that expect char *, which does not
11569 conform to the C standard.
11570 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
11571 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
11572 char * when the C standard requires it.
11574 * keyboard.c (read_char): Remove unused var.
11576 * eval.c: Port to Windows vsnprintf (Bug#8435).
11577 Include <limits.h>.
11578 (SIZE_MAX): Define if the headers do not.
11579 (verror): Do not give up if vsnprintf returns a negative count.
11580 Instead, grow the buffer. This ports to Windows vsnprintf, which
11581 does not conform to C99. Problem reported by Eli Zaretskii.
11582 Also, simplify the allocation scheme, by avoiding the need for
11583 calling realloc, and removing the ALLOCATED variable.
11585 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
11587 Remove invocations of doprnt, as Emacs now uses vsnprintf.
11588 But keep the doprint source code for now, as we might revamp it
11589 and use it again (Bug#8435).
11590 * lisp.h (doprnt): Remove.
11591 * Makefile.in (base_obj): Remove doprnt.o.
11592 * deps.mk (doprnt.o): Remove.
11594 error: Print 32- and 64-bit integers portably (Bug#8435).
11595 Without this change, on typical 64-bit hosts error ("...%d...", N)
11596 was used to print both 32- and 64-bit integers N, which relied on
11597 undefined behavior.
11598 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
11599 * lisp.h (error, verror): Mark as printf-like functions.
11600 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
11601 Report overflow in size calculations when allocating printf buffer.
11602 Do not truncate output string at its first null byte.
11603 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
11604 Truncate the output at a character boundary, since vsnprintf does not
11605 do that.
11606 * charset.c (check_iso_charset_parameter): Convert internal
11607 character to string before calling 'error', since %c now has the
11608 printf meaning.
11609 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
11610 overflow when computing char to be passed to 'error'. Do not
11611 pass Lisp_Object to 'error'; pass the integer instead.
11612 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
11613 formatted with plain %d.
11615 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
11617 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
11619 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
11621 * xterm.c (x_catch_errors): Remove duplicate declaration.
11623 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
11625 * xdisp.c, lisp.h (message_nolog): Remove; unused.
11627 2011-04-10 Jim Meyering <meyering@redhat.com>
11629 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
11630 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
11631 return ssize_t not "int", and use size_t as the buffer length.
11632 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
11633 * gnutls.h: Update declarations.
11634 * process.c (read_process_output): Use ssize_t, to match.
11635 (send_process): Likewise.
11637 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11639 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
11641 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11643 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
11644 Use unsigned char, to match FcChar8 type definition.
11646 * xterm.c (handle_one_xevent):
11647 * xmenu.c (create_and_show_popup_menu):
11648 * xselect.c (x_decline_selection_request)
11649 (x_reply_selection_request): Avoid type-punned deref of X events.
11651 2011-04-09 Eli Zaretskii <eliz@gnu.org>
11653 Fix some uses of `int' instead of EMACS_INT.
11654 * search.c (string_match_1, fast_string_match)
11655 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
11656 (scan_buffer, find_next_newline_no_quit)
11657 (find_before_next_newline, search_command, Freplace_match)
11658 (Fmatch_data): Make some `int' variables be EMACS_INT.
11660 * xdisp.c (display_count_lines): 3rd argument and return value now
11661 EMACS_INT. All callers changed.
11662 (pint2hrstr): Last argument is now EMACS_INT.
11664 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
11665 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
11666 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
11667 (decode_coding_utf_16, decode_coding_emacs_mule)
11668 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
11669 (decode_coding_ccl, decode_coding_charset)
11670 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
11671 (decode_coding_iso_2022, decode_coding_emacs_mule)
11672 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
11673 <char_offset, last_offset>: Declare EMACS_INT.
11674 (encode_coding_utf_8, encode_coding_utf_16)
11675 (encode_coding_emacs_mule, encode_invocation_designation)
11676 (encode_designation_at_bol, encode_coding_iso_2022)
11677 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
11678 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
11679 Declare EMACS_INT.
11680 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
11681 (encode_invocation_designation): Last argument P_NCHARS is now
11682 EMACS_INT.
11683 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
11684 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
11686 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
11687 All users changed.
11689 * ccl.c (Fccl_execute_on_string): Declare some variables
11690 EMACS_INT.
11692 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
11694 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
11696 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
11698 * process.c (Fformat_network_address): Doc fix.
11700 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
11702 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
11704 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
11706 * keyboard.c (read_char): Call Lisp function help-form-show,
11707 instead of using internal_with_output_to_temp_buffer.
11708 (Qhelp_form_show): New var.
11709 (syms_of_keyboard): Use DEFSYM macro.
11711 * print.c (internal_with_output_to_temp_buffer): Function deleted.
11713 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
11715 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
11717 * process.c (Flist_processes): Remove to Lisp.
11718 (list_processes_1): Delete.
11720 2011-04-06 Eli Zaretskii <eliz@gnu.org>
11722 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
11724 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
11726 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
11728 Fix more problems found by GCC 4.6.0's static checks.
11730 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
11732 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
11734 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
11736 * xdisp.c (vmessage): Mark as a printf-like function.
11738 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

11745 to system-supplied API.
11747 * eval.c (Fsignal): Remove excess argument to 'fatal'.
11749 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
11750 This avoids several warnings with gcc -Wstrict-overflow.
11751 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
11752 directly, rather than having caller test rule sign. This avoids
11753 some unnecessary tests.
11754 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
11755 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
11756 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
11758 * xfont.c (xfont_text_extents): Remove var that was set but not used.
11759 (xfont_open): Avoid unnecessary tests.
11761 * composite.c (composition_gstring_put_cache): Use unsigned integer.
11763 * composite.h, composite.c (composition_gstring_put_cache):
11764 Use EMACS_INT, not int, for length.
11766 * composite.h (COMPOSITION_DECODE_REFS): New macro,
11767 breaking out part of COMPOSITION_DECODE_RULE.
11768 (COMPOSITION_DECODE_RULE): Use it.
11769 * composite.c (get_composition_id): Remove unused local vars,
11770 by using the new macro.
11772 * textprop.c (set_text_properties_1): Change while to do-while,
11773 since the condition is always true at first.
11775 * intervals.c (graft_intervals_into_buffer): Mark var as used.
11776 (interval_deletion_adjustment): Return unsigned value.
11777 All uses changed.

11780 (exec_sentinel): Remove vars that were set but not used.
11781 (create_pty): Remove unnecessary "volatile"s.

11788 * syntax.c (scan_words): Remove var that was set but not used.
11789 (update_syntax_table): Use unsigned instead of int.
11791 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
11792 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
11793 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
11795 * print.c (print_error_message): Avoid int overflow.
11797 * font.c (font_list_entities): Redo for clarity,
11798 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
11800 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
11801 (font_score): Avoid potential overflow in diff calculation.
11803 * fns.c (substring_both): Remove var that is set but not used.
11804 (sxhash): Redo loop for clarity and to avoid wraparound warning.
11806 * eval.c (funcall_lambda): Rename local to avoid shadowing.
11808 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
11809 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
11810 can always succeed if overflow has undefined behavior.
11812 * search.c (boyer_moore, wordify): Remove vars set but not used.
11813 (wordify): Omit three unnecessary tests.
11815 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
11816 All callers changed. This avoids the need for an unused var.
11818 * casefiddle.c (casify_region): Remove var that is set but not used.
11820 * dired.c (file_name_completion): Remove var that is set but not used.
11822 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
11824 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
11825 (Finsert_file_contents): Remove unnecessary code checking fd.
11827 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
11828 Check for integer overflow on size calculations.
11830 * buffer.c (Fprevious_overlay_change): Remove var that is set
11831 but not used.
11833 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
11834 Remove vars that are set but not used.
11835 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
11836 (timer_check_2): Mark vars as initialized.
11838 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
11840 * image.c (lookup_image): Remove var that is set but not used.
11841 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
11843 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
11844 that are set but not used.
11846 * xfns.c (make_invisible_cursor): Don't return garbage
11847 if XCreateBitmapFromData fails (Bug#8410).
11849 * xselect.c (x_get_local_selection, x_handle_property_notify):
11850 Remove vars that are set but not used.
11852 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
11853 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
11855 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
11856 Remove var that is set but not used.
11857 (scroll_bar_windows_size): Now size_t, not int.
11858 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
11859 Check for overflow.
11861 * xfaces.c (realize_named_face): Remove vars that are set but not used.
11862 (map_tty_color) [!defined MSDOS]: Likewise.
11864 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
11866 * coding.c: Remove vars that are set but not used.
11867 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
11868 All callers changed.
11869 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
11870 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
11871 (decode_coding_charset): Remove vars that are set but not used.
11873 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
11874 that is set but not used.
11876 * print.c (print_object): Remove var that is set but not used.
11878 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
11879 The gnulib version avoids calling malloc in the usual case,
11880 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
11881 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
11882 * filelock.c (current_lock_owner): Likewise.
11883 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
11884 * sysdep.c: Include allocator.h, careadlinkat.h.

11890 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
11892 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
11893 first non-nil return value).

11907 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
11908 and thereabouts. All callers changed.
11909 (get_per_char_metric): Remove parameter `f', unused since
11910 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
11912 2011-04-02 Jim Meyering <meyering@redhat.com>
11914 do not dereference NULL upon failed strdup
11915 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.

11920 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
11922 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
11924 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
11925 later (Bug#8403).
11927 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>

11985 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
11987 * xdisp.c (redisplay_internal): Fix prototype.
11989 2011-03-31 Eli Zaretskii <eliz@gnu.org>
11991 * xdisp.c (SCROLL_LIMIT): New macro.
11992 (try_scrolling): Use it when setting scroll_limit.
11993 Limit scrolling to 100 screen lines.
11994 (redisplay_window): Even when falling back on "recentering",
11995 position point in the window according to scroll-conservatively,
11996 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
11998 (try_scrolling): When point is above the window, allow searching
11999 as far as scroll_max, or one screenful, to compute vertical
12000 distance from PT to the scroll margin position. This prevents
12001 try_scrolling from unnecessarily failing when
12002 scroll-conservatively is set to a value slightly larger than the
12003 window height. Clean up the case of PT below the margin at bottom
12004 of window: scroll_max can no longer be INT_MAX. When aggressive
12005 scrolling is in use, don't let point enter the opposite scroll
12006 margin as result of the scroll.
12007 (syms_of_xdisp) <scroll-conservatively>: Document the
12008 threshold of 100 lines for never-recentering scrolling.
12010 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12012 * dispextern.h (move_it_by_lines):
12013 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
12014 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
12015 (message_log_check_duplicate): Remove parameters `prev_bol' and
12016 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12017 (redisplay_internal): Remove parameter `preserve_echo_area',
12018 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12020 * indent.c (Fvertical_motion):
12021 * window.c (window_scroll_pixel_based, Frecenter):
12022 Don't pass `need_y_p' to `move_it_by_lines'.
12024 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12026 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12027 steal a few bits to be more compact.
12028 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12029 Remove unneeded casts.
12031 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12033 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12035 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12036 binding" message (bug#7967).
12038 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12040 Fix more problems found by GCC 4.6.0's static checks.
12042 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12043 Remove unused local var.
12045 * editfns.c (Fmessage_box): Remove unused local var.
12047 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12048 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12049 Omit unused local vars.
12050 * window.c (shrink_windows): Omit unused local var.
12051 * menu.c (digest_single_submenu): Omit unused local var.
12052 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12053 Omit unused local var.
12055 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12056 Don't assume string length fits in int.
12057 (keyremap_step, read_key_sequence): Use size_t for sizes.
12058 (read_key_sequence): Don't check last_real_key_start redundantly.
12060 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
12061 instead of alloca (Bug#8344).
12063 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12064 (Fbacktrace_frame): Don't assume nframes fits in int.
12066 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
12068 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
12069 concerns.
12071 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12073 * cm.c (calccost): Turn while-do into do-while, for clarity.
12075 * keyboard.c (syms_of_keyboard): Use the same style as later
12076 in this function when indexing through an array. This also
12077 works around GCC bug 48267.
12079 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12081 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12083 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12084 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12086 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12087 This avoids undefined behavior on integer overflow, and is a bit
12088 more convenient anyway since it is compared to a size_t variable.
12090 Variadic C functions now count arguments with size_t, not int.
12091 This avoids an unnecessary limitation on 64-bit machines, which
12092 caused (substring ...) to crash on large vectors (Bug#8344).
12093 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
12094 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

12098 * editfns.c (general_insert_function): Likewise.
12099 * eval.c (struct backtrace.nargs, interactive_p)
12100 (internal_condition_case_n, run_hook_with_args, apply_lambda)
12101 (funcall_lambda, mark_backtrace): Likewise.
12102 * fns.c (concat): Likewise.
12103 * frame.c (x_set_frame_parameters): Likewise.
12104 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12105 0 if not found, not -1. All callers changed.
12107 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12108 (stack_copy_size): Now size_t, not int.
12109 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12111 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12113 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
12114 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12115 All callers changed.
12117 * lisp.h (multibyte_char_to_unibyte):
12118 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
12119 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12120 * character.h (CHAR_TO_BYTE8):
12121 * cmds.c (internal_self_insert):
12122 * editfns.c (general_insert_function):
12123 * keymap.c (push_key_description):
12124 * search.c (Freplace_match):
12125 * xdisp.c (message_dolog, set_message_1): All callers changed.
12127 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12129 * keyboard.c (safe_run_hook_funcall): New function.
12130 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12131 don't set the hook to nil, but remove the offending function instead.
12132 (Qcommand_hook_internal): Remove, unused.
12133 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12134 Vcommand_hook_internal.
12136 * eval.c (enum run_hooks_condition): Remove.
12137 (funcall_nil, funcall_not): New functions.
12138 (run_hook_with_args): Call each function through a `funcall' argument.
12139 Remove `cond' argument, now redundant.
12140 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
12141 (Frun_hook_with_args_until_failure): Adjust accordingly.
12142 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
12144 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12146 * dispextern.h (string_buffer_position): Remove declaration.
12148 * print.c (strout): Remove parameter `multibyte', unused since
12149 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
12151 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
12152 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
12153 All callers changed.
12155 * w32.c (_wsa_errlist): Use braces for struct initializers.

12165 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
12166 All callers changed.
12168 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12170 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

12181 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
12183 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12185 * nsmenu.m (runDialogAt): Remove argument to timer_check.
12187 2011-03-27 Glenn Morris <rgm@gnu.org>
12189 * syssignal.h: Replace RETSIGTYPE with void.
12190 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
12191 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
12192 Replace SIGTYPE with void everywhere.
12193 * s/usg5-4-common.h (SIGTYPE): Remove definition.
12194 * s/template.h (SIGTYPE): Remove commented out definition.
12196 2011-03-26 Eli Zaretskii <eliz@gnu.org>
12198 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
12199 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
12201 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
12203 * w32.c (read_unc_volume): Use parameter `henum', instead of
12204 global variable `wget_enum_handle'.
12206 * keymap.c (describe_vector): Remove parameters `indices' and
12207 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

12213 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
12214 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
12215 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
12217 * keyboard.c (read_char):
12218 * w32menu.c (w32_menu_display_help):
12219 * xmenu.c (show_help_event, menu_help_callback):
12220 Adjust calls to `show_help_echo'.
12222 * gtkutil.c (xg_maybe_add_timer):
12223 * keyboard.c (readable_events):
12224 * process.c (wait_reading_process_output):
12225 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
12227 * insdel.c (adjust_markers_gap_motion):
12228 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
12229 (gap_left, gap_right): Don't call it.
12231 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

12302 2011-03-23 Julien Danjou <julien@danjou.info>
12304 * term.c (Fsuspend_tty, Fresume_tty):
12305 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
12306 * window.c (temp_output_buffer_show):
12307 * insdel.c (signal_before_change):
12308 * frame.c (Fhandle_switch_frame):
12309 * fileio.c (Fdo_auto_save):
12310 * emacs.c (Fkill_emacs):
12311 * editfns.c (save_excursion_restore):
12312 * cmds.c (internal_self_insert):
12313 * callint.c (Fcall_interactively):
12314 * buffer.c (Fkill_all_local_variables):
12315 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12316 Use Frun_hooks.
12317 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
12318 unconditionally since it does the check itself.
12320 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12322 Fix more problems found by GCC 4.5.2's static checks.
12324 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12325 the first time through the loop, since we know p0 < p1 then.
12326 This also avoids a gcc -Wstrict-overflow warning.
12328 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12329 leading to a memory leak, possible in functions like
12330 load_charset_map_from_file that can allocate an unbounded number
12331 of objects (Bug#8318).
12333 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12334 that could (at least in theory) be that large.
12336 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12337 This is less likely to overflow, and avoids undefined behavior if
12338 overflow does occur. All callers changed. Use strtoul to scan
12339 for the unsigned long integer.
12340 (pint2hrstr): Simplify and tune code slightly.
12341 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
12343 * scroll.c (do_scrolling): Work around GCC bug 48228.
12344 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
12346 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
12347 This also avoids a warning with gcc -Wstrict-overflow.
12348 (validate_x_resource_name): Simplify count usage.
12349 This also avoids a warning with gcc -Wstrict-overflow.
12351 * fileio.c (Fcopy_file): Report error if fchown or fchmod
12352 fail (Bug#8306).
12354 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12356 * process.c (Fmake_network_process): Use socklen_t, not int,
12357 where POSIX says socklen_t is required in portable programs.
12358 This fixes a porting bug on hosts like 64-bit HP-UX, where
12359 socklen_t is wider than int (Bug#8277).
12360 (Fmake_network_process, server_accept_connection):
12361 (wait_reading_process_output, read_process_output):
12362 Likewise.
12364 * process.c: Rename or move locals to avoid shadowing.
12365 (list_processes_1, Fmake_network_process):
12366 (read_process_output_error_handler, exec_sentinel_error_handler):
12367 Rename or move locals.
12368 (Fmake_network_process): Define label "retry_connect" only if needed.
12369 (Fnetwork_interface_info): Fix pointer signedness.
12370 (process_send_signal): Add cast to avoid pointer signedness problem.
12371 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
12372 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
12374 Make tparam.h and terminfo.c consistent.
12375 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12376 Include tparam.h instead, since it declares them.
12377 * cm.h (PC): Remove extern decl; tparam.h now does this.
12378 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12379 * terminfo.c: Include tparam.h, to check interfaces.
12380 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12381 (tparam): Adjust signature to match interface in tparam.h;
12382 this removes some undefined behavior. Check that outstring and len
12383 are zero, which they always are with Emacs.
12384 * tparam.h (PC, BC, UP): New extern decls.
12386 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12387 (xftfont_open): Rename locals to avoid shadowing.
12389 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
12390 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
12391 (OTF_TAG_SYM): Omit macro if not needed.
12392 (ftfont_list): Remove unused local.
12393 (get_adstyle_property, ftfont_pattern_entity):
12394 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
12395 Rename locals to avoid shadowing.
12397 * xfont.c (xfont_list_family): Mark var as initialized.
12399 * xml.c (make_dom): Now static.
12401 * composite.c (composition_compute_stop_pos): Rename local to
12402 avoid shadowing.
12403 (composition_reseat_it): Remove unused locals.
12404 (find_automatic_composition, composition_adjust_point): Likewise.
12405 (composition_update_it): Mark var as initialized.
12406 (find_automatic_composition): Mark vars as initialized,

12438 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12440 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
12441 This should get cleaned up, so that child_setup has the
12442 same signature on all platforms.
12444 * callproc.c (call_process_cleanup): Now static.
12445 (relocate_fd): Rename locals to avoid shadowing.
12447 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
12449 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
12450 not to be necessary, and produces flickering.

12456 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

12475 * makefile.w32-in: Update dependencies.
12477 2011-03-17 Eli Zaretskii <eliz@gnu.org>

12503 * unexelf.c (unexec): Name an expression,
12504 to avoid gcc -Wbad-function-cast warning.
12505 Use a different way to cause a compilation error if anyone uses
12506 n rather than nn, a way that does not involve shadowing.
12507 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
12509 * deps.mk (unexalpha.o): Remove; unused.
12511 New file unexec.h, the (simple) interface for unexec (Bug#8267).
12512 * unexec.h: New file.
12513 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
12514 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
12515 Depend on unexec.h.
12516 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
12517 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
12518 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

12570 * lisp.h (get_system_name, get_operating_system_release):
12571 Move decls here, to check interfaces.
12572 * process.c (get_operating_system_release): Move decl to lisp.h.
12573 * xrdb.c (get_system_name): Likewise.
12574 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
12575 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
12576 some of which prompt warnings from gcc -Wbad-function-cast.
12577 (Fformat_time_string, Fencode_time, Finsert_char):
12578 (Ftranslate_region_internal, Fformat):
12579 Rename or remove local vars to avoid shadowing.
12580 (Ftranslate_region_internal): Mark var as initialized.
12582 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
12583 avoid shadowing.
12585 * lisp.h (eassert): Check that the argument compiles, even if
12586 ENABLE_CHECKING is not defined.
12588 * data.c (Findirect_variable): Name an expression, to avoid
12589 gcc -Wbad-function-cast warning.

12600 they're used.
12601 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

12603 needed otherwise.
12604 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
12605 (GC_STRING_CHARS): Remove; not used.
12606 (Fmemory_limit): Cast sbrk's returned value to char *.
12608 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
12609 avoids undefined behavior in theory.
12611 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
12613 Use functions, not macros, for up- and down-casing (Bug#8254).
12614 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12615 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
12616 to use the following functions instead of these macros.
12617 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
12618 EMACS_INT, since callers assume the returned value fits in int.
12619 (upcase1): Likewise, for UPCASE_TABLE.
12620 (uppercasep, lowercasep, upcase): New static inline functions.
12621 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
12622 the race-condition problem in the old DOWNCASE.
12624 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

12627 (regex_compile, re_search_2, re_match_2_internal):
12628 Remove unused local vars.
12629 (FREE_VAR): Rewrite so as not to use empty "else",
12630 which gcc can warn about.
12631 (regex_compile, re_match_2_internal): Mark locals as initialized.
12632 (RETALLOC_IF): Define only if needed.
12633 (WORDCHAR_P): Likewise. This one is never needed, but is used
12634 only in a comment talking about a compiler bug, so put inside
12635 the #if 0 of that comment.
12636 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
12637 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
12638 Remove; unused.
12640 * search.c (boyer_moore): Rename locals to avoid shadowing.
12641 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
12642 (PREV_CHAR_BOUNDARY): Likewise.
12644 * search.c (simple_search): Remove unused var.
12646 * dired.c (compile_pattern): Move decl from here ...
12647 * lisp.h: ... to here, so that it can be checked.
12648 (struct re_registers): New forward decl.
12650 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
12652 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
12653 All uses changed.
12654 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
12655 Rename locals to avoid shadowing.
12656 (Fvertical_motion): Mark locals as initialized.
12658 * casefiddle.c (casify_object, casify_region): Now static.
12659 (casify_region): Mark local as initialized.
12661 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
12663 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
12664 New macros, so that the caller can use some names other than
12665 gcpro1, gcpro2, etc.
12666 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
12667 of the new macros.
12668 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
12669 argument, for consistency with GCPRO2_VAR, etc: it is now the
12670 prefix of the variable, not the variable itself. All uses
12671 changed.
12672 * dired.c (directory_files_internal, file_name_completion):
12673 Rename locals to avoid shadowing.
12675 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
12676 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
12677 dired.c's scmp function, had undefined behavior.
12678 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12679 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
12680 * buffer.h: ... to here, because these macros use current_buffer,
12681 and the new implementation with inline functions needs to have
12682 current_buffer in scope now, rather than later when the macros
12683 are used.
12684 (downcase, upcase1): New static inline functions.
12685 (DOWNCASE, UPCASE1): Reimplement using these functions.
12686 This avoids undefined behavior in expressions like
12687 DOWNCASE (x) == DOWNCASE (y), which previously suffered
12688 from race conditions in accessing the global variables
12689 case_temp1 and case_temp2.
12690 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
12691 * lisp.h (case_temp1, case_temp2): Remove their decls.
12692 * character.h (ASCII_CHAR_P): Move from here ...
12693 * lisp.h: ... to here, so that the inline functions mentioned
12694 above can use them.
12696 * dired.c (directory_files_internal_unwind): Now static.
12698 * fileio.c (file_name_as_directory, directory_file_name):
12699 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
12700 Now static.
12701 (file_name_as_directory): Use const pointers when appropriate.
12702 (Fexpand_file_name): Likewise. In particular, newdir might
12703 point at constant storage, so make it a const pointer.
12704 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
12705 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
12706 signedness issues.
12707 (Fset_file_times, Finsert_file_contents, auto_save_error):
12708 Rename locals to avoid shadowing.
12710 * minibuf.c (choose_minibuf_frame_1): Now static.
12711 (Ftry_completion, Fall_completions): Rename or remove locals
12712 to avoid shadowing.
12714 * marker.c (bytepos_to_charpos): Remove; unused.
12716 * lisp.h (verify_bytepos, count_markers): New decls,
12717 so that gcc does not warn that these functions aren't declared.
12719 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
12720 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
12721 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
12722 (copy_text): Remove unused local var.
12724 * filelock.c (within_one_second): Now static.
12725 (lock_file_1): Rename local to avoid shadowing.
12727 * buffer.c (fix_overlays_before): Mark locals as initialized.
12728 (fix_start_end_in_overlays): Likewise. This function should be
12729 simplified by using pointers-to-pointers, but that's a different
12730 matter.
12731 (switch_to_buffer_1): Now static.
12732 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
12733 (report_overlay_modification): Rename locals to avoid shadowing.
12735 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
12736 Fix pointer signedness issue.
12737 (sys_subshell): Mark local as volatile if checking for lint,
12738 to suppress a gcc -Wclobbered warning that does not seem to be right.
12739 (MAXPATHLEN): Define only if needed.
12741 * process.c (serial_open, serial_configure): Move decls from here ...
12742 * systty.h: ... to here, so that they can be checked.
12744 * fns.c (get_random, seed_random): Move extern decls from here ...
12745 * lisp.h: ... to here, so that they can be checked.
12747 * sysdep.c (reset_io): Now static.
12748 (wait_for_termination_signal): Remove; unused.
12750 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
12751 (copy_keymap_item, append_key, push_text_char_description):
12752 Now static.
12753 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
12754 (DENSE_TABLE_SIZE): Remove; unused.
12755 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
12756 (describe_map_tree):
12757 Rename locals to avoid shadowing.
12759 * keyboard.c: Declare functions static if they are not used elsewhere.
12760 (echo_char, echo_dash, cmd_error, top_level_2):
12761 (poll_for_input, handle_async_input): Now static.
12762 (read_char, kbd_buffer_get_event, make_lispy_position):
12763 (make_lispy_event, make_lispy_movement, apply_modifiers):
12764 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
12765 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
12766 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
12767 (read_key_sequence, read_char): Mark locals as initialized.

12772 * alloc.c (mark_kboards): ... from here.
12774 * lisp.h (force_auto_save_soon): New decl.
12776 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
12777 (DEFINE_DUMMY_FUNCTION): New macro.
12778 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
12779 Use it.
12780 (main): Add casts to avoid warnings
12781 if GCC considers string literals to be constants.
12783 * lisp.h (fatal_error_signal): Add decl, since it's exported.
12785 * dbusbind.c: Pointer signedness fixes.
12786 (xd_signature, xd_append_arg, xd_initialize):
12787 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12788 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12789 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
12790 (Fdbus_register_signal): Use SSDATA when the context wants char *.
12792 * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
12793 if GCC considers string literals to be constants.
12794 (Fdbus_register_service, Fdbus_register_method): Remove unused vars.

12826 (w32_system_caret_hwnd, w32_system_caret_height, w32_system_caret_x)
12827 (w32_system_caret_y, Qfile_name_history):
12828 * w32font.c (w32font_driver, QCantialias, QCotf, QClang):

12832 * w32proc.c (Qlocal, report_file_error):
12833 * w32term.c (Vwindow_system, updating_frame):
12834 * w32uniscribe.c (initialized, uniscribe_font_driver):
12835 Remove unneeded extern declarations.
12837 2011-03-14 Chong Yidong <cyd@stupidchicken.com>
12839 * buffer.c (Fmake_indirect_buffer): Fix incorrect assertions.
12841 2011-03-13 Chong Yidong <cyd@stupidchicken.com>

12844 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
12845 These macros can no longer be used for assignment.
