41 2012-07-11 Glenn Morris <rgm@gnu.org>
43 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
44 since nothing has defined it on these platforms.

58 2012-07-11 John Wiegley <johnw@newartisans.com>
60 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
61 function attribute, so we only use it if it exists in the
62 compiler.
64 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
66 Avoid call to strlen in fast_c_string_match_ignore_case.

113 * s/aix4-2.h (unix): Remove; no longer needed.
115 EMACS_TIME simplification (Bug#11875).
116 This replaces macros (which typically do not work in GDB)
117 with functions, typedefs and enums, making the code easier to debug.
118 The functional style also makes code easier to read and maintain.
119 * systime.h: Include <sys/time.h> on all hosts, not just if
120 WINDOWSNT, since 'struct timeval' is needed in general.
121 (EMACS_TIME): Now a typedef, not a macro.
122 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
123 not macros.

128 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
129 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
130 which are not functions. All uses rewritten to use:
131 (make_emacs_time): New function.
132 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
133 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
134 not functions. All uses rewritten to use the following, respectively:
135 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
136 (add_emacs_time, sub_emacs_time): New functions.
137 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
138 * fileio.c (Fcopy_file):
139 * xterm.c (XTflash): Get the current time closer to when it's used.
140 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

149 * lread.c (openp):
150 * nsmenu.m (ns_update_menubar):
151 * regex.c (regerror):
152 Prefer memcpy to strncpy and strncat when either will do.

154 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
155 (menu_separator_name_p):
156 * nsmenu.m (ns_update_menubar):
157 Prefer memcmp to strncmp when either will do.
158 * nsterm.m: Include <ftoastr.h>.
159 (ns_get_color):
160 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
161 Prefer snprintf to strncpy.
162 * nsterm.m (ns_term_init):
163 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
164 * nsterm.m (ns_term_init):
165 Avoid the need for strncpy, by using build_string or
166 make_unibyte_string directly. Use dtoastr, not snprintf.
167 * process.c (Fmake_network_process): Diagnose service names that
168 are too long, rather than silently truncating them or creating
169 non-null-terminated names.
170 (Fnetwork_interface_info): Likewise, for interface names.
171 * sysdep.c (system_process_attributes) [GNU_LINUX]:
172 Prefer sprintf to strncat.

178 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
179 Clarify fallback case.
181 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

185 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
186 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
187 where argument type is known to be a Lisp_Cons.
189 2012-07-10 Tom Tromey <tromey@redhat.com>
191 * bytecode.c (BYTE_CODE_THREADED): New macro.
192 (BYTE_CODES): New macro. Replaces all old byte-code defines.

199 Optimize pure C strings initialization.
200 * lisp.h (make_pure_string): Fix prototype.
201 (build_pure_c_string): New function, defined as static inline. This
202 provides a better opportunity to optimize away calls to strlen when
203 the function is called with compile-time constant argument.
204 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
205 argument, adjust users accordingly. Use build_pure_c_string where
206 appropriate.
207 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
208 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
209 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
211 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
213 Avoid calls to strlen in miscellaneous functions.
214 * buffer.c (init_buffer): Use precalculated len, adjust if needed.

220 Avoid calls to strlen in path processing functions.
221 * fileio.c (file_name_as_directory): Add comment. Change to add
222 srclen argument and return the length of result. Adjust users
223 accordingly.
224 (directory_file_name): Fix comment. Change to add srclen argument,
225 swap 1st and 2nd arguments to obey the common convention. Adjust
226 users accordingly.
227 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
229 2012-07-10 Glenn Morris <rgm@gnu.org>

235 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
236 * s/gnu.h (DATA_START): Move definitions to configure.
238 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
239 We include usg5-4-common.h, which defines them both.
241 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
242 O_RDONLY already includes it).
244 Stop ns builds setting the EMACSLOADPATH environment variable.
245 * nsterm.m (ns_load_path): Rename from ns_init_paths.
246 Now it does not set EMACSLOADPATH, just returns the load-path string.
247 * nsterm.h: Update accordingly.
248 * lread.c [HAVE_NS]: Include nsterm.h.
249 (init_lread) [HAVE_NS]: Use ns_load_path.
250 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
252 2012-07-09 Glenn Morris <rgm@gnu.org>
254 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
255 since the included bsd-common.h does so.
257 Stop ns builds setting the EMACSPATH environment variable.
258 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
259 (ns_init_paths): Do not set EMACSPATH.
260 * nsterm.h (ns_exec_path): Add it.
261 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
262 Use ns_exec_path.
264 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
266 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
268 * process.c (wait_reading_process_output): 'waitchannels' was unset
269 when read_kbd || !NILP (wait_for_cell); fix this.
271 Add GCC-style 'const' attribute to functions that can use it.
272 * character.h (char_resolve_modifier_mask):
273 * keyboard.h (make_ctrl_char):
274 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
275 (init_character_once, next_almost_prime, init_fns, init_image)
276 (flush_pending_output, init_sound):

283 Add decls with ATTRIBUTE_CONST.
285 Minor improvements to make_formatted_string.
286 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
287 where int is good enough, as vsprintf returns an int.
288 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
290 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
292 Use make_formatted_string to avoid double length calculation.
293 * lisp.h (make_formatted_string): New prototype.
294 * alloc.c (make_formatted_string): New function.
295 * buffer.c (Fgenerate_new_buffer_name): Use it.
296 * dbus.c (syms_of_dbusbind): Likewise.
297 * editfns.c (Fcurrent_time_zone): Likewise.
298 * filelock.c (get_boot_time): Likewise.
299 * frame.c (make_terminal_frame, set_term_frame_name)

319 Move marker debugging code under MARKER_DEBUG.
320 * marker.c (MARKER_DEBUG): Move marker debugging code under
321 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
322 for bootstrap with --enable-checking (~3x slowdown reported
323 by Juanma Barranquero <lekktu@gmail.com>).
324 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
326 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
328 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
329 See <http://bugs.gnu.org/11825#29>.
331 2012-07-08 Eli Zaretskii <eliz@gnu.org>
333 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
334 has no font, use the frame's font. (Bug#11813)
335 (display_line): Add commentary about displaying truncation glyphs
336 on GUI frames.
337 (produce_special_glyphs): Move here from term.c.
339 * term.c (produce_special_glyphs): Move to xdisp.c.
341 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
342 section.
344 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
346 * xdisp.c (display_line): Avoid warning about implicit declaration
347 of FRAME_FONT.
349 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
351 * lisp.h: Remove empty conditional.
353 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
355 * lread.c (load_path_check): Now static.
357 Fix some minor --with-ns problems found by static checking.
358 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
359 (x_set_font) [!HAVE_X_WINDOWS]:
360 * image.c (xpm_load_image) [HAVE_NS]:
361 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
362 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
363 Remove unused local.
364 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
365 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
366 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
367 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
368 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
369 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
370 Fix pointer signedness problem.
371 * xfaces.c (FRAME_X_FONT_TABLE):
372 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
374 2012-07-07 Glenn Morris <rgm@gnu.org>
376 * lread.c (load_path_check): New function, split from init_lread.
377 (init_lread): Reorganize. Motivation:
378 If EMACSLOADPATH is set, check/warn about that rather than the
379 defaults, which we are not going to use. Hence we can remove
380 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
381 Don't warn if site-lisp directories are missing.
382 If not installed, start from a blank load-path, since
383 PATH_LOADSEARCH refers to the eventual installation directories.
385 2012-07-07 Eli Zaretskii <eliz@gnu.org>
387 Support truncation and continuation glyphs on GUI frames, when
388 fringes are disabled. (Bug#11832)
389 * xdisp.c (init_iterator): Get dimensions of truncation and
390 continuation glyphs even if on GUI frames. Adjust
391 it->last_visible_x on GUI frames when the left or right fringes,
392 or both, are absent.
393 (start_display, move_it_in_display_line_to): Handle the case of a
394 GUI frame without a fringe to display continuation or truncation
395 glyphs.
396 (insert_left_trunc_glyphs): Support GUI frames: make sure
397 truncation glyphs overwrite enough glyphs from the current line to
398 have sufficient space in pixels.
399 (display_line): Support truncation and continuation glyphs on GUI
400 frames. If some spare pixels are left on the line after inserting
401 the truncation glyphs, fill that space with a stretch glyph of a
402 suitably computed width.
404 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
405 produce_glyphs, to support GUI sessions.
407 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
409 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
411 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
413 Do not require float-time's arg to fit in time_t (Bug#11825).
414 This works better on hosts where time_t is unsigned, and where
415 float-time is applied to the (negative) difference between two times.
416 * editfns.c (decode_time_components): Last arg is now double *,
417 not int *, and means to store all the result as a double, without
418 worrying about whether the seconds part fits in time_t.
419 All callers changed.
420 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
421 All callers changed.
422 (Ffloat_time): Do not fail merely because the specified time falls
423 outside of time_t range.
425 2012-07-07 Glenn Morris <rgm@gnu.org>
427 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

429 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
431 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
433 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
434 Update dependencies.
436 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
438 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
440 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
441 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
442 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
443 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
444 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
445 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
447 * xfont.c (compare_font_names): Redo to omit the need for casts.
449 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
451 * xfns.c (Fx_change_window_property): Doc fix.
452 * w32fns.c (Fx_change_window_property): Doc fix.
454 * w32fns.c (Fx_window_property): Accept the same arguments as the
455 X Windows version. Doc fix.
456 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
458 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
459 Eli Zaretskii <eliz@gnu.org>
461 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
462 Windows-specific code from nt/config.nt moved here.
463 Obsolete settings removed.
465 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
467 * process.c: Avoid unnecessary calls to gettime.
468 (wait_reading_process_output): Don't get the time of day
469 when gobbling data immediately and not waiting, as there's no need
470 for it in that case. This removes a FIXME.
472 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
474 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
475 is defined (Bug#11768).
477 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
479 Fix marker debugging code.
480 * marker.c (byte_char_debug_check): Do not perform the check
481 if buffer is not multibyte.
482 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
483 Call byte_char_debug_check with correct arguments.
485 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
487 Compile marker debugging code only if ENABLE_CHECKING is defined.
488 * marker.c (byte_char_debug_check, count_markers):
489 Use only if ENABLE_CHECKING is defined.
490 (byte_debug_flag): Remove.
491 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
492 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
494 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
496 Avoid code repetition in marker-related functions.
497 * marker.c (attach_marker): New function.
498 (Fset_marker, set_marker_restricted, set_marker_both)
499 (set_marker_restricted_both): Use it.
500 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
501 Consistently rename charno to charpos.
502 (marker_position): Add eassert.
503 (marker_byte_position): Convert to eassert.

516 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
517 * composite.c (autocmp_chars): Likewise.
518 * editfns.c (buildmark): Remove.
519 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
520 (save_restriction_save): Use build_marker.
521 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
522 * window.c (save_window_save): Likewise.
524 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
526 Do not use Fdelete_overlay in delete_all_overlays
527 to avoid redundant calls to unchain_overlay.
528 * buffer.c (drop_overlay): New function.
529 (delete_all_overlays, Fdelete_overlay): Use it.
530 * minibuf.c (get_minibuffer): Fix comment.
532 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
534 Port to OpenBSD 5.1 amd64.
535 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
536 This is needed for OpenBSD, and should be harmless on all BSD systems.
537 Also, include <sys/sysctl.h>, as it should be available on all
538 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
539 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
540 use p_pid member, not kp_proc.pid.
542 2012-07-06 Glenn Morris <rgm@gnu.org>
544 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
546 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
548 More xmalloc and related cleanup.

558 * xterm.c:
559 Omit needless casts involving void * pointers and allocation.
560 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
561 as the former is more robust if P's type is changed.
562 Prefer xzalloc to xmalloc + memset 0.
563 Simplify malloc-or-realloc to realloc.
564 Don't worry about xmalloc returning a null pointer.
565 Prefer xstrdup to xmalloc + strcpy.
566 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
567 growing it.
568 * keyboard.c (apply_modifiers_uncached): Prefer local array to
569 alloca of a constant.
571 2012-07-05 Eli Zaretskii <eliz@gnu.org>
573 * xdisp.c (display_line): Fix horizontal pixel coordinates when
574 hscroll is larger than the line width. Fixes long and futile
575 looping inside extend_face_to_end_of_line (on a TTY) producing
576 glyphs that are not needed and thrown away.
578 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
580 * marker.c (set_marker_restricted_both): Simplify by using
581 clip_to_bounds.

594 followed by gtk_box_set_homogeneous (Bug#11768).
595 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
596 (update_theme_scrollbar_width, xg_create_scroll_bar):
597 Use gtk_scrollbar_new (Bug#11768).
598 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
599 (is_box_type): New function (Bug#11768).
600 (xg_tool_item_stale_p): Call is_box_type.
601 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
602 with default display (Bug#11768).
604 2012-07-05 Eli Zaretskii <eliz@gnu.org>
606 * xdisp.c (window_hscroll_limited): New function.
607 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
608 coordinates when window's hscroll is set to insanely large
609 values. (Bug#11857)
611 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
613 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

675 Problem reported by Troels Nielsen in
676 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
678 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
680 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
681 This should be fixed in a better way; see Eli Zaretskii in
682 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
683 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
685 * fileio.c (time_error_value): Rename from special_mtime.
686 The old name's problems were noted by Eli Zaretskii in
687 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
689 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
690 This variable's comment says Emacs needs at least one GDB-visible
691 symbol of type enum pvec_type, to work around GDB problems.
692 The symbol's value doesn't matter.
694 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
695 that causes compilation to fail on pre-C99 compilers.
697 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
699 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

702 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
704 * buffer.c (init_buffer_once): Fix initialization of
705 headers for buffer_defaults and buffer_local_symbols.
706 Reported by Juanma Barranquero <lekktu@gmail.com>.
708 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
710 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
711 * lisp.h (enum pvec_type): Use fewer bits.
712 (PSEUDOVECTOR_SIZE_BITS): New constant.
713 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
714 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
715 change in pvec_type.

722 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
723 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
724 (sweep_vectors): Use it. Use local var `total_bytes' instead of
725 abusing vector->header.next.nbytes.
726 (live_vector_p): Use PVEC_TYPE.
727 (mark_object): Adapt code to extract pvectype. Use switch.
729 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
731 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
732 Tighten new eassert a bit.
734 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
736 Fix compilation with --enable-gcc-warnings and -O1
737 optimization level.
738 * doprnt.c (doprnt): Change type of tem to int, initialize
739 to avoid compiler warning. Add eassert.
740 * search.c (simple_search): Initialize match_byte to avoid
741 compiler warning. Add eassert.
743 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
745 Avoid weird behavior with large horizontal scrolls.
746 Without this change, for example, large hscroll values would
747 mess up Emacs's display on Fedora 15 x86, presumably due to
748 overflows in int calculations in the display code.
749 Also, if buffers had long lines, Emacs would freeze.
750 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
751 (set_window_hscroll): New function, containing the old guts of
752 Fset_window_hscroll. Return the clipped value.
753 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
754 This avoids the need to check against PTRDIFF_MAX.
756 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
758 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
760 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
762 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
764 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
765 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
766 since GCC 4.4.6 issues a bogus warning for them.
768 Fix bugs in file timestamp newness comparisons.
769 * fileio.c (Ffile_newer_than_file_p):
770 * lread.c (Fload): Use full timestamp resolution of files,
771 not just the 1-second resolution, so that files that are only
772 slightly newer still count as newer.
773 * fileio.c (Ffile_newer_than_file_p): Don't assume file
774 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
776 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
778 * fileio.c: Improve handling of file time marker. (Bug#11852)
779 (special_mtime): New function.
780 (Finsert_file_contents, Fverify_visited_file_modtime):
781 Use it to set special mtime values consistently.
783 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
785 * fileio.c (Finsert_file_contents): Properly handle st_mtime
786 marker for non-existing file. (Bug#11852)
788 2012-07-03 Glenn Morris <rgm@gnu.org>
790 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
791 and did not make it into globals.h).
793 2012-07-03 Tom Tromey <tromey@redhat.com>

831 2012-07-03 Glenn Morris <rgm@gnu.org>
833 * lisp.h (Frandom): Make it visible to C.
834 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
835 buffer for invisible buffers. (Bug#1229)
837 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
839 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
840 values which aren't power of 2.
841 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
842 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
843 accordingly.
845 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
847 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
849 * alloc.c (mark_object): Revert part of last patch to use `switch'.
851 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
853 * alloc.c (allocate_vector_block): Remove redundant
854 calls to mallopt if DOUG_LEA_MALLOC is defined.
855 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
856 avoid calls to mallopt if zero_vector is returned.
858 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
860 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
861 is enabled, avoid dereferencing NULL current_sblock if
862 running undumped.
864 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
866 Cleanup basic buffer management.
867 * buffer.h (struct buffer): Change layout to use generic vector
868 marking code. Fix some comments. Change type of 'clip_changed'
869 to bitfield. Remove unused #ifndef old.
870 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
871 (GET_OVERLAYS_AT): Fix indentation.
872 (for_each_per_buffer_object_at): New macro.

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

880 Lisp area of struct buffer.
881 (mark_object): Use it. Adjust marking of misc objects
882 and related comments.
884 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
886 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
887 wrapper that is not needed because the wrapped code is a no-op (zero
888 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
889 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
891 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
893 * alloc.c (mark_buffer): Simplify. Remove prototype.
894 (mark_object): Add comment. Reorganize marking of vector-like
895 objects. Use CHECK_LIVE for all vector-like objects except buffers
896 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
897 redundant calls to mark_vectorlike for bool vectors.
899 2012-06-30 Glenn Morris <rgm@gnu.org>
901 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
903 * epaths.in (PATH_SITELOADSEARCH): New.
904 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
905 This is rather than relying on --enable-locallisppath elements
906 having "site-lisp" in their names. (Bug#10208#25, 11658)
908 2012-06-30 Eli Zaretskii <eliz@gnu.org>
910 * w32proc.c (sys_select): Accept and ignore one more argument.
912 * w32.c (emacs_gnutls_pull): Call select with one more argument.

920 * msdos.c (sys_select): Accept one more argument and ignore it.
922 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
923 adapt data types and code to that.
925 * dosfns.c:
926 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
927 which clashes with the gnulib function of the same name.
929 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
931 * font.c (font_style_to_value, font_style_symbolic)

942 * xdisp.c (try_window_id): Undo last change.
944 * w32.c (getwd): Adjust commentary about startup_dir.
945 (init_environment): Always call sys_access, even in non-MSVC
946 builds. Don't chdir to the directory of the Emacs executable.
947 This undoes code from 1997 which was justified by the need to
948 "avoid conflicts when removing and renaming directories". But its
949 downside was that every relative file name was being interpreted
950 relative to the directory of the Emacs executable, which can never
951 be TRT. In particular, it broke sys_access when called with
952 relative file names.
953 (sys_access): Map GetLastError to errno.
955 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
957 * window.h (struct window): Change type of 'fringes_outside_margins'
958 to bitfield. Fix comment. Adjust users accordingly.

1137 * alloc.c: Remove build_string.
1138 * lisp.h: Define build_string as static inline. This provides

1145 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1147 Use sprintf return value instead of invoking strlen on result.
1148 In the old days this wasn't portable, since some sprintf
1149 implementations returned char *. But they died out years ago and
1150 Emacs already assumes sprintf returns int.
1151 Similarly for float_to_string.
1152 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

1159 * xfns.c (syms_of_xfns):
1160 Use sprintf or float_to_string result to avoid need to call strlen.
1161 * data.c (Fnumber_to_string):
1162 Use make_unibyte_string, since the string must be ASCII.
1163 * lisp.h, print.c (float_to_string): Now returns int length.
1164 * term.c (produce_glyphless_glyph):
1165 Use sprintf result rather than recomputing it.
1167 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1168 * Makefile.in (ALL_CFLAGS):
1169 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

1175 strcasecmp if available.

1196 * xfns.c (x_window): Remove redundant cast.
1198 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1200 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
1201 `const char *' to `char *' to avoid compiler warning.
1203 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1205 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1206 instead of truncating it to 63 (admittedly a generous limit).
1208 * process.c: Fix spelling and caps in comments.

1261 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1263 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

1265 * dispnew.c (Fsleep_for, sit_for):
1266 * keyboard.c (kbd_buffer_get_event):
1267 * process.c (Faccept_process_output):
1268 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1269 This improves on the previous patch, which introduced a bug
1270 when time_t is unsigned and as wide as intmax_t.
1271 See <http://bugs.gnu.org/9000#51>.
1273 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1275 * dispnew.c (sit_for, Fsleep_for):
1276 * keyboard.c (kbd_buffer_get_event):

1302 language ID in the event parameters.
1304 * w32term.c (w32_read_socket): Put the new keyboard codepage into
1305 event.code, not the obscure "character set ID".

1328 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
1329 Privately reported by Herbert J. Skuhra.

1336 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1338 Support higher-resolution time stamps (Bug#9000).
1339 The time stamps are only nanosecond-resolution at the C level,
1340 since that's the best that any real-world system supports now.
1341 But they are picosecond-resolution at the Lisp level, as that's
1342 easy, and leaves room for future OS improvements.
1344 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1345 (LIBES): Use it.
1347 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1348 Don't get current time unless it's needed.
1350 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1351 now provides it if it's absent.
1352 (start_atimer): Port to higher-res time stamps.
1353 Check for time stamp overflow. Don't get current time more
1354 often than is needed.
1356 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1357 Include systime.h, not time.h.
1358 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1360 * dired.c: Include stat-time.h.
1361 (Ffile-attributes): File times now have higher resolution.
1363 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
1364 (struct image): Timestamp now has higher resolution.
1366 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1367 has at least microseconds now. All uses removed.
1368 (update_frame, update_single_window, update_window, update_frame_1)
1369 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1371 * editfns.c (time_overflow): Now extern.
1372 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1373 (float-time, Fformat_time_string, Fcurrent_time_string)
1374 (Fcurrent_time_zone): Accept and generate higher-resolution
1375 time stamps.
1376 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
1377 (decode_time_components, lisp_seconds_argument): New functions.
1378 (make_time): Now static.
1379 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1380 Report an error if the time is invalid, rather than having the caller
1381 do that.
1383 * fileio.c: Include <stat-time.h>
1384 (Fcopy_file): Copy higher-resolution time stamps.
1385 Prefer to set the time stamp via a file descriptor if that works.
1386 (Fset_file_times, Finsert_file_contents, Fwrite_region)
1387 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1388 (Fvisited_file_modtime, Fset_visited_file_modtime):
1389 Support higher-resolution time stamps.
1391 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1393 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1395 * image.c (prepare_image_for_display, clear_image_cache)
1396 (lookup_image): Port to higer-resolution time stamps.
1398 * keyboard.c (start_polling, bind_polling_period):
1399 Check for time stamp overflow.
1400 (read_char, kbd_buffer_get_event, timer_start_idle)
1401 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1402 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1403 Port to higher-resolution time stamps. Do not assume time_t is signed.
1404 (decode_timer): New function. Timers are now vectors of length 9,
1405 not 8, to accommodate the picosecond component.
1406 (timer_check_2): Use it.
1408 * nsterm.m (select_timeout, timeval_subtract): Remove.
1409 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1410 as they're a bit more accurate and handle overflow better.
1411 (ns_select): Change prototype to be compatible with pselect.
1412 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1413 * nsterm.h (ns_select): Adjust prototype.
1415 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1416 us-resolution time stamps.
1417 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1419 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1421 * lisp.h (time_overflow): New decl.
1422 (wait_reading_process_output): First arg is now intmax_t, not int,
1423 to accommodate larger waits.
1425 * process.h (struct Lisp_Process.read_output_delay):
1426 Now counts nanoseconds, not microseconds.
1427 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1428 EMACS_HAS_USECS.
1429 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1430 (wait_reading_process_output):
1431 Port to ns-resolution time stamps.
1432 (Faccept_process_output, wait_reading_process_output):
1433 Check for time stamp overflow. Do not assume time_t is signed.
1434 (select_wrapper): Remove; we now use pselect.
1435 (Fprocess_attributes): Now generates ns-resolution time stamps.
1437 * sysdep.c: Include utimens.h. Don't include utime.h
1438 or worry about struct utimbuf; gnulib does that for us now.
1439 (gettimeofday): Remove; gnulib provides a substitute.
1440 (make_timeval): New function.
1441 (set_file_times): Now sets ns-resolution time stamps.
1442 New arg FD; all uses changed.
1443 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1444 (system_process_attributes):
1445 Now returns ns-resolution time stamp. All uses changed.
1446 Check for time stamp overflow.
1448 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1449 provides a substitute now.
1451 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1452 since it guarantees struct timespec.
1453 (EMACS_TIME): Now struct timespec, so that we can support
1454 ns-resolution time stamps.
1455 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1456 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1457 (EMACS_USECS): Remove.
1458 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1459 so multiply the arg by 1000 before storing it.
1460 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1461 New macros.

1469 (make_timeval, make_lisp_time, decode_time_components): New decls.
1470 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1471 that it mishandled time_t overflow. You can't compare by subtracting!
1472 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1473 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1475 * term.c: Include <sys/time.h>.
1476 (timeval_to_Time): New function, for proper overflow wraparound.
1477 (term_mouse_position, term_mouse_click): Use it.
1479 * undo.c (record_first_change): Support higher-resolution time stamps
1480 in the undo buffer.
1481 (Fprimitive_undo): Use them when restoring time stamps.
1483 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1484 (w32_get_internal_run_time):
1485 Port to higher-resolution Emacs time stamps.
1486 (ltime): Now accepts single 64-bit integer, as that's more convenient
1487 for callers.
1489 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1491 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1492 for compatibility with pselect. Support ns-resolution time stamps.
1494 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1496 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1497 Check for time stamp overflow, and support ns-resolution time stamps.
1499 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1500 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1501 (timeval_subtract): Remove; no longer needed.
1502 (XTflash, XTring_bell, x_wait_for_event):
1503 Port to ns-resolution time stamps. Don't assume time_t is signed.

1509 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1511 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1512 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1513 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1514 staticidx goes up to 1597 out of 1600 = 0x640.)
1516 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1518 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1519 Otherwise, the umask might be mistakenly 0 while handling input signals.
1521 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
1523 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

1528 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
1529 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
1530 access to `contents' member of Lisp_Vector objects with AREF and ASET
1531 where appropriate.
1533 2012-06-19 Chong Yidong <cyd@gnu.org>
1535 * frame.c (delete_frame): When selecting a frame on a different
1536 text terminal, do not alter the terminal's top-frame.
1538 * xdisp.c (format_mode_line_unwind_data): Record the target
1539 frame's selected window and its terminal's top-frame.
1540 (unwind_format_mode_line): Restore them.
1541 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
1542 Callers changed.
1543 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1544 since tty frames can be explicitly named.
1545 (prepare_menu_bars): Likewise.
1547 * term.c (Ftty_top_frame): New function.
1549 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1551 Port byte-code-meter to modern targets.
1552 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
1553 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
1554 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
1555 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
1556 (METER_1, METER_2): Simplify.
1558 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
1560 * data.c (Fdefalias): Return `symbol' (bug#11686).
1562 2012-06-18 Martin Rudalics <rudalics@gmx.at>
1564 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
1565 gets killed during executing of this function (Bug#11665).
1566 Try to always return Qt when the buffer has been actually killed.
1567 (Vkill_buffer_query_functions): In doc-string say that functions
1568 run by this hook should not change the current buffer.
1570 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1572 Fix recently-introduced process.c problems found by static checking.
1573 * process.c (write_queue_push, write_queue_pop, send_process):

1576 (send_process): Remove unused local.
1578 2012-06-17 Chong Yidong <cyd@gnu.org>

1588 writes (Bug#10815).
1590 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
1592 * lisp.h (eassert): Assume C89 or later.
1593 This removes the need for CHECK.
1594 (CHECK): Remove. Its comments about always evaluating its
1595 argument were confusing, as 'eassert' typically does not evaluate
1596 its argument.
1598 * coding.c (produce_chars): Use ptrdiff_t, not int.
1600 * xterm.c (x_draw_underwave): Check for integer overflow.
1601 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

1694 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
1695 If all the glyphs of the glyph row came from strings, and we have no
1696 cursor positioning clues, put the cursor on the first glyph of the
1697 row.
1698 (handle_face_prop): Use chunk-relative overlay string index when
1699 indexing into it->string_overlays array. (Bug#11653)

1721 Simplify lisp.h in minor ways that should not affect code.
1722 * lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
1723 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
1724 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

1787 as the union type is for debugging, not for production.
1788 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
1789 Use an inline function on all platforms when using the union type,
1790 since this is simpler and 'static inline' can be used portably

1874 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
1876 * xdisp.c (vmessage): Treat frame message as multibyte.
1877 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
1878 would generate the diagnostic "Making \302\247 buffer-local while
1879 let-bound!".
1881 2012-06-08 Eli Zaretskii <eliz@gnu.org>
1883 * dispnew.c (showing_window_margins_p): Undo last change, which
1884 was done due to an inadvertent commit.
1885 (adjust_frame_glyphs_for_frame_redisplay): Do call
1886 showing_window_margins_p.
1888 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>

1896 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
1897 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
1899 2012-06-08 Eli Zaretskii <eliz@gnu.org>
1901 * alloc.c (allocate_vectorlike): Fix last change.
1903 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
1905 Block-based vector allocation of small vectors.
1906 * lisp.h (struct vectorlike_header): New field `nbytes',
1907 adjust comment accordingly.
1908 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
1909 to denote vector blocks. Adjust users (live_vector_p,
1910 mark_maybe_pointer, valid_lisp_object_p) accordingly.
1911 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
1912 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
1913 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
1914 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
1915 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

1921 (sweep_vectors): New functions.
1922 (allocate_vectorlike): Return `zero_vector' as the only vector of
1923 0 items. Allocate new vector from block if vector size is less than
1924 or equal to VBLOCK_BYTES_MAX.
1925 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
1926 (init_alloc_once): Add call to init_vectors.
1928 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
1930 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
1932 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
1934 * doprnt.c (doprnt): Truncate multibyte char correctly.
1935 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
1936 would mishandle a string argument "Xc" if X was a multibyte
1937 character of length 2: it would truncate after X's first byte
1938 rather than including all of X.
1940 2012-06-06 Chong Yidong <cyd@gnu.org>
1942 * buffer.c (word_wrap): Doc fix.

1968 (note_mode_line_or_margin_highlight): If there is no help echo,
1969 use mode-line-default-help-echo. Handle the case where the mouse
1970 position is past the end of the mode line string.
1972 * buffer.c (buffer_local_value_1): New function, split from
1973 Fbuffer_local_value; can return Qunbound.
1974 (Fbuffer_local_value): Use it.
1975 (Vmode_line_format): Docstring tweaks.
1977 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

1989 * minibuf.c (Fassoc_string): Remove duplicate declaration.
1991 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
1992 Convert pctcpu and pctmem to Lisp float properly.
1993 Let the compiler fold better, as 100.0/0x8000 is exact.
1995 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
1997 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
1998 cons_block.
2000 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2002 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2004 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2006 For a 'struct window', replace some Lisp_Object fields to
2007 bitfields where appropriate, remove unused fields.
2008 * window.h (struct window): Remove unused 'last_mark_x' and
2009 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2010 change it's type from Lisp_Object to bitfield.
2011 Change type of 'force_start', 'optional_new_start',
2012 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2013 fields from Lisp_Object to bitfield. Adjust users accordingly.
2015 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2017 Pacify gcc -Wdouble-precision when using Xaw.
2018 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2019 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2020 Use 'float' consistently, rather than 'float' in most places
2021 and 'double' in a couple of places.
2023 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2025 * xdisp.c (handle_stop): Detect whether we have overlay strings
2026 loaded by testing it->current.overlay_string_index to be
2027 non-negative, instead of checking whether n_overlay_strings is
2028 positive. (Bug#11587)
2030 2012-05-31 Chong Yidong <cyd@gnu.org>
2032 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2034 * doc.c (Fsubstitute_command_keys): Doc fix.
2036 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2038 * search.c (search_buffer): Remove calls to
2039 r_alloc_inhibit_buffer_relocation, as it is now called by
2040 maybe_unify_char, which was the cause of relocation of buffer text
2041 in bug#11519.
2043 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2045 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2046 for the duration of call to load_charset, to avoid problems with
2047 callers of maybe_unify_char that access buffer text through C
2048 pointers.
2050 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2051 decrement the inhibition flag, instead of just setting or
2052 resetting it.
2054 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2056 Remove obsolete '#define static' cruft.
2057 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2058 This #undef was "temporary" in 2000; it is no longer needed
2059 now that '#define static' has gone away.
2060 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2061 (gray_bitmap_bits): Remove; no longer needed.
2062 All uses replaced with definiens.
2063 * xterm.c: Include "bitmaps/gray.xbm".
2065 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2067 Clean up __executable_start, monstartup when --enable-profiling.
2068 The following changes affect the code only when profiling.
2069 * dispnew.c (__executable_start): Rename from safe_bcopy.
2070 Define only on platforms that need it.
2071 * emacs.c: Include <sys/gmon.h> when profiling.
2072 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2073 (__executable_start): Remove decl, since lisp.h does it now.
2074 (safe_bcopy): Remove decl; no longer has that name.
2075 (main): Coalesce #if into single bit of code, for simplicity.
2076 Cast pointers to uintptr_t, since standard libraries want integers
2077 and not pointers.
2078 * lisp.h (__executable_start): New decl.
2080 2012-05-31 Glenn Morris <rgm@gnu.org>
2082 * image.c (Fimagemagick_types): Doc fix.

2103 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2105 Do not create empty overlays with the evaporate property (Bug#9642).
2106 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2107 Bug#9642, but explicitly check that the buffer the overlay would
2108 be moved to is live and rearrange lines to make sure that errors
2109 will not put the overlay in an inconsistent state.
2110 (Fdelete_overlay): Cosmetics.
2112 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2114 * w32term.c (my_bring_window_to_top): New function.
2115 (x_raise_frame): Use handle returned by DeferWindowPos, which
2116 could be different from the original one.

2126 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2128 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2129 This avoids undefined behavior that might cause the eassert
2130 to not catch an out-of-range value.
2132 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2134 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

2146 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2148 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2149 Only r_alloc_inhibit_buffer_relocation needed to be added;
2150 the others were already declared.
2152 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2153 before checking whether it's out of range. Put the check inside
2154 eassert. See
2155 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2157 2012-05-27 Ken Brown <kbrown@cornell.edu>
2159 * callproc.c (Fcall_process): Restore a line that was accidentally
2160 commented out in the 2011-02-13 change (bug#11547).
2162 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2164 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2165 defined on ralloc.c.
2167 * buffer.c [REL_ALLOC]: Remove prototypes of
2168 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2169 they are now on lisp.h.
2171 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2173 * search.c (search_buffer): Use it to inhibit relocation of buffer
2174 text while re_search_2 is doing its job, because re_search_2 is
2175 passed C pointers to buffer text. (Bug#11519)
2177 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2178 Update value to 24.
2180 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2181 state after an additional call to move_it_in_display_line_to, keep
2182 the values of it->max_ascent and it->max_descent found for the
2183 entire line.
2184 (pos_visible_p): Revert the comparison against bottom_y to what it
2185 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2186 (Bug#11464)
2188 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2190 Fix coding-related core dumps with gcc -ftrapv.
2191 The code was computing A - B, where A and B are pointers, and B is
2192 random garbage. This can lead to core dumps on platforms that
2193 have special pointer registers, and it also leads to core dumps on
2194 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2195 A - B only when B is initialized properly.
2196 * coding.c (coding_set_source, coding_set_destination): Return void.
2197 (coding_change_source, coding_change_destinations): New functions,
2198 with the old behaviors of coding_set_source and coding_set_destination.
2199 All callers that need an offset changed to use these new functions.
2201 2012-05-26 Glenn Morris <rgm@gnu.org>
2203 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

2211 * w32console.c: Include window.h.
2212 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2213 New functions.
2214 (initialize_w32_display): Initialize mouse-highlight data.
2216 * w32inevt.c: Include termchar.h and window.h.
2217 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2218 moves, call note_mouse_highlight. If help_echo changed, call
2219 gen_help_event to produce help-echo message in the echo area.
2220 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2221 highlight info.
2223 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2225 * lread.c (read1): Simplify slightly to avoid an overflow warning
2226 with GCC 4.7.0 on x86-64.
2228 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2230 * bidi.c (bidi_mirror_char): Revert last change: an int is
2231 definitely wide enough here.
2233 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2235 Fix integer width and related bugs (Bug#9874).

2243 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2244 (mark_vectorlike):
2245 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2246 (allocate_pseudovector):
2247 Use int, not EMACS_INT, where int is wide enough.
2248 (inhibit_garbage_collection, Fgarbage_collect):
2249 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2250 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2251 int might not be wide enough.
2252 (bidi_cache_search, bidi_cache_find, bidi_init_it)

2254 (bidi_at_paragraph_end, bidi_find_paragraph_start)
2255 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2256 (bidi_level_of_next_char, bidi_move_to_visually_next):
2257 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2258 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
2259 (Fkill_buffer, Fset_buffer_major_mode)
2260 (advance_to_char_boundary, Fbuffer_swap_text)

2262 (overlay_touches_p, struct sortvec, record_overlay_string)
2263 (overlay_strings, recenter_overlay_lists)
2264 (adjust_overlays_for_insert, adjust_overlays_for_delete)
2265 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

2267 (Foverlay_recenter, last_overlay_modification_hooks_used)
2268 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2270 (validate_region): Omit unnecessary test for b <= e,
2271 since that's guaranteed by the previous test.
2272 (adjust_overlays_for_delete): Avoid pos + length overflow.
2273 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2274 (report_overlay_modification):
2275 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2276 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2277 Omit pointer cast, which isn't needed anyway, and doesn't work
2278 after the EMACS_INT -> ptrdiff_t change.
2279 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2280 * buffer.h: Adjust decls to match defn changes elsewhere.
2281 (struct buffer_text, struct buffer):
2282 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2283 Use EMACS_INT, not int, where int might not be wide enough.
2284 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
2285 not int, to avoid needless 32-bit limit on 64-bit hosts.
2286 (exec_byte_code): Use tighter memory-full test, one that checks
2287 for alloca overflow. Don't compute the address of the object just
2288 before an array, as that's not portable. Use EMACS_INT, not
2289 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2290 * callint.c (Fcall_interactively):
2291 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2292 * callproc.c (call_process_kill, Fcall_process):
2293 Don't assume pid_t fits into an Emacs fixnum.
2294 (call_process_cleanup, Fcall_process, child_setup):

2302 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2303 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2304 (casify_object): Avoid integer overflow when overallocating buffer.
2305 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
2306 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
2307 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
2308 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2309 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2310 integers are now checked earlier. All uses replaced with XINT.

2313 For CCL_MapSingle, check that content and value are in int range.

2315 Check that Vcode_version_map_vector is a vector.
2316 (resolve_symbol_ccl_program): Check that vector header is in range.
2317 Always copy the vector, so that we can check its contents reliably
2318 now rather than having to recheck each instruction as it's being
2319 executed. Check that vector words fit in 'int'.
2320 (ccl_get_compiled_code, Fregister_ccl_program)
2321 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2322 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

2324 contents are in range.
2325 (Fccl_execute_on_string): Check that status is in range.

2335 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2336 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
2337 avoid mishandling large integers.

2351 that's not true for gb10830 4-byte on a 32-bit host. Allow
2352 invalid_code to be a cons, for the same reason. Require code_offset
2353 to be a character. Avoid int overflow if max_char is close
2354 to INT_MAX.
2355 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2356 this is intended anyway and avoids some undefined behavior.
2357 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2358 INDEX_TO_CODE_POINT, as that's what it expects.
2359 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.

2363 integer-overflow issues.

2365 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2366 where the argument is EMACS_INT, and this behavior is not intended.
2367 * chartab.c (Fmake_char_table, Fset_char_table_range)
2368 (uniprop_get_decoder, uniprop_get_encoder):
2369 Don't assume fixnum fits in int.
2370 * cmds.c (move_point): New function, that does the gist of

2372 for integer overflow more accurately.

2374 (Fforward_line, Fend_of_line, internal_self_insert)
2375 (internal_self_insert):

3001 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
3002 (Fx_show_tip):
3003 Check that fixnums are in proper range for system types.
3004 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
3005 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):
3006 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3007 (Fx_change_window_property): Don't assume fixnums fit in int.
3008 * xfont.c (xfont_chars_supported):
3009 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3010 * xmenu.c (Fx_popup_dialog, set_frame_menubar)
3011 (create_and_show_popup_menu, create_and_show_dialog, xmenu_show):
3012 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3013 * xml.c (parse_region):
3014 * xrdb.c (magic_file_p):
3015 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3016 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
3017 (x_get_local_selection, x_reply_selection_request)
3018 (x_handle_selection_request, wait_for_property_change):
3019 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3020 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
3021 short is wide enough.
3022 (x_send_client_event): Don't assume fixnum fits in int.
3023 * xterm.c (x_x_to_emacs_modifiers):
3024 Don't assume EMACS_INT overflows nicely into int.
3025 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
3026 may come from Lisp.
3027 (handle_one_xevent): NATNUMP can eval its arg twice.
3028 (x_connection_closed):
3029 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3030 * xterm.h: Adjust decls to match defn changes elsewhere.
3031 (struct scroll_bar): Use struct vectorlike_header
3032 rather than rolling our own approximation.
3033 (SCROLL_BAR_VEC_SIZE): Remove; not used.
3035 2012-05-25 Glenn Morris <rgm@gnu.org>
3037 * lisp.mk (lisp): Update for more files being compiled now.
3039 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
3041 * lread.c: Remove `read_pure' which makes no difference.
3042 (read_pure): Remove var.
3043 (unreadpure): Remove function.
3044 (readevalloop): Don't call read_list with -1 flag.
3045 (read1, read_vector): Don't test read_pure any more.
3046 (read_list): Simplify.
3048 * fileio.c, character.h: Minor style tweaks.
3050 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
3052 * window.h (clip_changed): Remove useless declaration.
3054 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
3056 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
3057 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
3059 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
3061 Remove src/m/*.
3062 This directory predates autoconf and is no longer needed nowadays.
3063 Move its few remaining bits of functionality to where they're needed.
3064 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
3065 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
3066 * m/template.h: Remove.
3067 * Makefile.in (M_FILE): Remove. All uses removed.
3068 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
3069 * lisp.h (USE_LSB_TAG):
3070 * mem-limits.h (EXCEEDS_LISP_PTR):
3071 Use VAL_MAX, not VALBITS, in #if.
3072 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
3073 (EMACS_UINT): Define unconditionally now.
3074 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3075 (BITS_PER_EMACS_INT): New constants, replacing
3076 what used to be in config.h, but not useful in #if.
3077 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3078 define them any more.
3079 (VAL_MAX): New macro.
3080 (VALMASK): Use it.
3081 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3082 BITS_PER_EMACS_INT, in #if.
3083 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3084 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3085 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3086 * s/ms-w32.h (DATA_START):
3087 Move here from removed file m/intel386.h.
3088 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3089 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3091 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
3093 Assume C89 or later.
3094 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
3095 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
3096 (xrealloc):
3097 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

3099 * textprop.c, tparam.c (NULL): Remove.
3100 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
3101 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
3102 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
3103 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3104 * xterm.c (input_signal_count): Assume volatile works.
3106 2012-05-21 Ken Brown <kbrown@cornell.edu>
3108 * xgselect.c (xg_select): Fix first argument in call to 'select'
3109 (bug#11508).
3111 2012-05-20 Ken Brown <kbrown@cornell.edu>
3113 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3114 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3116 2012-05-19 Ken Brown <kbrown@cornell.edu>
3118 * xfns.c (x_in_use): Remove `static' qualifier.
3119 * xterm.h (x_in_use): Declare.
3120 * xgselect.c: Include xterm.h.
3121 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3122 and `display_arg' (bug#9754).
3124 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3126 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3128 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3129 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3131 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3133 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3135 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3136 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3138 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3139 reference to image_cache->refcount.
3140 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3142 2012-05-17 Juri Linkov <juri@jurta.org>
3144 * search.c (Fword_search_regexp, Fword_search_backward)
3145 (Fword_search_forward, Fword_search_backward_lax)
3146 (Fword_search_forward_lax): Move functions to isearch.el
3147 (bug#10145, bug#11381).
3149 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3151 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3153 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3155 * lread.c (init_obarray): Declare Qt and Qnil as special.
3157 2012-05-14 Glenn Morris <rgm@gnu.org>
3159 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3160 Put "libexec" before "bin", for the sake of init_callproc_1.
3162 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3164 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3166 * unexaix.c: Port to more-recent AIX compilers.
3167 (report_error, report_error_1, make_hdr, copy_sym)
3168 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3169 Make arguments const char *, not char *, to avoid violations of C
3170 standard and to fix some AIX warnings reported by Gilles Pion.
3172 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3174 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3175 already have overlays loaded.
3176 (handle_single_display_spec): Before returning without displaying
3177 fringe bitmap, synchronize the bidi iterator with the main display
3178 iterator, by calling iterate_out_of_display_property.
3179 (iterate_out_of_display_property): Detect buffer iteration by
3180 testing that it->string is a Lisp string.
3181 (get_next_display_element): When the current object is exhausted,
3182 and there's something on it->stack, call set_iterator_to_next to
3183 proceed with what's on the stack, instead of returning zero.
3184 (set_iterator_to_next): If called at the end of a Lisp string,
3185 proceed to consider_string_end without incrementing string
3186 position. Don't increment display vector index past the end of
3187 the display vector. (Bug#11417)
3188 (pos_visible_p): Don't report a position visible when move_it_to
3189 stopped at the last line of window, which happens to be scanned
3190 backwards by the bidi iteration. (Bug#11464)
3192 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3194 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3195 and right-margin display specs even if the spec is invalid or we
3196 are on a TTY, and thus unable to display on the fringes.
3197 That's because the text with the property will not be displayed anyway,
3198 so we need to signal to the caller that this is a "replacing"
3199 display spec. This fixes display when the spec is invalid or we
3200 are on a TTY.
3202 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3204 * unexaix.c (make_hdr): Fix typo in prototype.
3205 This bug broke the build on AIX. Problem reported by Gilles Pion.
3207 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3209 * keyboard.c (kbd_buffer_get_event): Read special events also in
3210 batch mode. (Bug#11415)
3212 2012-05-12 Glenn Morris <rgm@gnu.org>
3214 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3216 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3218 * lisp.mk (lisp): Add newcomment.elc.
3220 2012-05-12 Glenn Morris <rgm@gnu.org>
3222 * Makefile.in (MKDIR_P): New, set by configure.
3223 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3225 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3227 Remove unused function hourglass_started.
3228 * dispextern.h (hourglass_started):
3229 * w32fns.c (hourglass_started):
3230 * xdisp.c (hourglass_started): Remove.
3232 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3234 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3235 Update dependencies.
3237 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3239 * xgselect.c (xg_select): Put maxfds+1 into a var.
3240 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3242 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3244 2012-05-10 Dave Abrahams <dave@boostpro.com>
3246 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3247 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3249 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3251 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3252 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3253 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3254 Initialize xd_registered_buses.
3256 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3258 Untag more efficiently if USE_LSB_TAG.
3259 This is based on a proposal by YAMAMOTO Mitsuharu in
3260 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3261 For an admittedly artificial (nth 8000 longlist) benchmark on
3262 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3263 Emacs's overall text size by 1%.
3264 * lisp.h (XUNTAG): New macro.
3265 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3266 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3267 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3268 * eval.c (Fautoload):
3269 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3270 * frame.h (XFRAME): Use XUNTAG.
3272 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3273 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3274 Remove unportable assumptions about print widths of types like
3275 dbus_uint32_t.
3276 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3277 intptr_t when converting between pointer and integer, to avoid GCC
3278 warnings about wrong width.
3280 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3282 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3283 stack for each reader_thread, instead of defaulting to 8MB
3284 determined by the linker. This avoids failures in creating
3285 subprocesses on Windows 7, see the discussion in this thread:
3286 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3288 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3290 Fix up display of the *Minibuf-0* buffer in the mini window.
3291 * keyboard.c (read_char): Don't clear the echo area if there's no
3292 message to clear.
3293 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3294 contents of *Minibuf-0*) if there's no message displayed in its stead.
3296 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3298 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3299 batch mode.
3301 2012-05-06 Chong Yidong <cyd@gnu.org>
3303 * lisp.mk (lisp): Update.
3305 2012-05-05 Jim Meyering <meyering@redhat.com>
3307 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3309 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3311 * data.c (PUT_ERROR): New macro.
3312 (syms_of_data): Use it. Add new error type `user-error'.
3313 * undo.c (user_error): New function.
3314 (Fprimitive_undo): Use it.
3315 * print.c (print_error_message): Adjust print style for `user-error'.
3316 * keyboard.c (user_error): New function.
3317 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3319 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3321 Do not limit current-time-string to years 1000..9999.
3322 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3323 (Fcurrent_time_string): Support any year that is supported by the
3324 underlying localtime representation. Don't use asctime, as it
3325 has undefined behavior for years outside the range -999..9999.
3327 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3329 Fix race conditions involving setenv, gmtime, localtime, asctime.
3330 Without this fix, interrupts could mess up code that uses these
3331 nonreentrant functions, since setting TZ invalidates existing
3332 tm_zone or tzname values, and since most of these functions return
3333 pointers to static storage.
3334 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3335 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3336 Grow the critical sections to include not just invoking
3337 localtime/gmtime, but also accessing these functions' results
3338 including their tm_zone values if any, and any related TZ setting.
3339 (format_time_string): Last arg is now struct tm *, not struct tm **,
3340 so that the struct tm is saved in the critical section.
3341 All callers changed. Simplify allocation of initial buffer, partly
3342 motivated by the fact that memory allocation needs to be outside
3343 the critical section.
3345 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3347 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3348 with RESET_INTERVAL.
3350 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3351 Remove duplicated buffer name initialization.
3353 2012-05-02 Jim Meyering <jim@meyering.net>
3355 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3357 * xfns.c (x_window): Use xstrdup (Bug#11375).
3359 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3361 * xdisp.c (pos_visible_p): If already at a newline from the
3362 display string before the 'while' loop, don't walk back the glyphs
3363 from it3.glyph_row. Solves assertion violation when the display
3364 string begins with a newline (egg.el). (Bug#11367)
3366 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3368 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3369 Move to simple.el.
3371 2012-05-01 Glenn Morris <rgm@gnu.org>
3373 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3374 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3375 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3376 All were removed before 23.1.
3378 * dispnew.c: Remove HAVE_LIBNCURSES test;
3379 it is always true on relevant platforms.
3381 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3382 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3384 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3386 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3388 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3389 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3390 Remove.
3392 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3394 Do not avoid creating empty evaporating overlays (Bug#9642).
3395 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3396 That is, do not delete an evaporating overlay if it becomes
3397 empty after its bounds are adjusted to fit within its buffer.
3398 This fix caused other problems, and I'm reverting it until we get
3399 to the bottom of them.
3401 2012-04-27 Chong Yidong <cyd@gnu.org>
3403 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3405 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3407 * xdisp.c (pos_visible_p): If the window start position is beyond
3408 ZV, start the display from buffer beginning. Prevents assertion
3409 violation in init_iterator when the minibuffer window is scrolled
3410 via the scroll bar.
3412 * window.c (window_scroll_pixel_based): Likewise.
3414 2012-04-27 Chong Yidong <cyd@gnu.org>
3416 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3418 2012-04-27 Glenn Morris <rgm@gnu.org>
3420 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3421 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3423 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3425 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3426 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3428 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3430 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3431 display element, check also the underlying string or buffer
3432 character. (Bug#11341)
3434 * w32menu.c: Include w32heap.h.
3435 (add_menu_item): If the call to AppendMenuW (via
3436 unicode_append_menu) fails, disable Unicode menus only if we are
3437 running on Windows 9X/Me.
3439 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3441 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3442 (xgetint): Add missing shift for LSB tags.
3444 2012-04-24 Martin Rudalics <rudalics@gmx.at>

3452 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3453 manipulation of :loaded-from data.
3455 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

3462 Do not create empty overlays with the evaporate property (Bug#9642).
3463 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3464 if it becomes empty after its bounds are adjusted to fit within
3465 its buffer. Without this fix, in a nonempty buffer (let ((o
3466 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3467 yields an empty overlay that has the evaporate property, which is
3468 not supposed to happen.

3575 (mem_init, mem_insert, mem_insert_fixup):
3576 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
3577 (NEED_MEM_INSERT): Remove; no longer needed.
3579 2012-04-22 Leo Liu <sdl.web@gmail.com>

3583 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
3585 * sysdep.c [__FreeBSD__]: Minor cleanups.
3586 (list_system_processes, system_process_attributes) [__FreeBSD__]:
3587 Use Emacs indenting style more consistently. Avoid some casts.

3607 is nil.
3608 (print_object): Check for cycles even when print-circle is nil and
3609 print-gensym is t, but only check print_depth if print-circle is nil.
3611 2012-04-20 Chong Yidong <cyd@gnu.org>
3613 * process.c (wait_reading_process_output): If EIO occurs on a pty,
3614 set the status to "failed" and ensure that sentinel is run.
3616 2012-04-20 Glenn Morris <rgm@gnu.org>

3629 farther than the first row after the header line, if any.
3630 Don't consider the header-line row as "partially visible", even if
3631 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
3633 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

3668 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
3669 New extern decls, to avoid calling undeclared functions.
3670 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
3671 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3672 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
3673 (NEED_MEM_INSERT): New macro.
3674 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
3675 Remove one incorrect comment and fix another.

3688 [REL_ALLOC]: ... to here, to check interface.
3689 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
3690 Remove decls. This fixes an "It stinks!".
3692 * alloc.c (which_symbols): Fix alignment issue / type clash.
3694 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
3696 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

3707 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
3709 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
3710 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
3711 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
3712 * s/netbsd.h, s/sol2-6.h:
3713 Remove definition of GC_MARK_STACK, since the default now works.
3714 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
3715 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
3716 no longer the default.
3717 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
3719 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
3721 * lread.c (lisp_file_lexically_bound_p):

3742 2012-04-11 Daniel Colascione <dancol@dancol.org>
3744 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3745 against is gone. It's better to use vfork now so that when Cygwin
3746 gains a new, working vfork, we use it automatically (bug#10398).
3748 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
3750 * window.c (save_window_save): Obey window-point-insertion-type.

3769 being loaded (bug#10424).
3771 2012-04-09 Glenn Morris <rgm@gnu.org>
3773 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
3774 not just in the obarray, before snarfing them. (Bug#11036)

3789 (emacs_gnutls_read): Use new log functions,
3790 `gnutls_handshakes_tried' process member, and

3792 attempts per process (connection).
3794 2012-04-09 Chong Yidong <cyd@gnu.org>

3801 * minibuf.c (Fread_variable): Callers changed.
3803 2012-04-09 Eli Zaretskii <eliz@gnu.org>
3805 * xdisp.c (set_cursor_from_row): If the display string appears in
3806 the buffer at position that is closer to point than the position
3807 after the display string, display the cursor on the first glyph of
3808 the display string. Fixes cursor display when a 'display' text
3809 property immediately follows invisible text. (Bug#11094)
3811 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
3813 composite.c: use 'double' consistently
3814 * composite.c (get_composition_id): Use 'double' consistently
3815 instead of converting 'float' to 'double' and vice versa; this is
3816 easier to understand and avoids a GCC warning.
3818 2012-04-09 Glenn Morris <rgm@gnu.org>
3820 * Makefile.in: Generate leim-list with bootstrap-emacs, in
3821 preparation for dumping it with emacs. (Bug#4789)

3865 [!WINDOWSNT]: New macros.
3866 (init_libxml2_functions, libxml2_loaded_p): New functions.
3867 (parse_region): Call fn_xmlCheckVersion instead of using the macro
3868 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
3869 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
3870 Calls xmlCleanupParser only if libxml2 was loaded (or statically
3871 linked in).
3872 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
3873 Call init_libxml2_functions before calling libxml2 functions.
3874 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
3876 * emacs.c: Don't include libxml/parser.h.
3877 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
3878 xmlCleanupParser directly.

3882 2012-04-07 Eli Zaretskii <eliz@gnu.org>
3884 * indent.c (Fvertical_motion): If there is a display string at
3885 point, use it.vpos to compute how many lines to backtrack after
3886 move_it_to point. (Bug#11133)
3888 2012-04-06 Eli Zaretskii <eliz@gnu.org>
3890 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
3891 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
3892 about subtle differences between FETCH_CHAR* and STRING_CHAR*
3893 macros related to unification of CJK characters. For the details,
3894 see the discussion following the message here:
3895 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
3897 2012-04-04 Chong Yidong <cyd@gnu.org>
3899 * keyboard.c (Vdelayed_warnings_list): Doc fix.
3901 2012-04-01 Eli Zaretskii <eliz@gnu.org>
3903 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
3904 instead of alloca. (Bug#11138)
3906 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
3908 * w32menu.c (is_simple_dialog): Properly check lisp types.
3909 (Bug#11141)
3911 2012-03-31 Eli Zaretskii <eliz@gnu.org>
3913 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
3914 position we get to after a call to move_it_to fails the
3915 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
3916 only if we wind up in a string from display property. (Bug#11063)
3918 * window.c (Fdelete_other_windows_internal): Invalidate the row
3919 and column information about mouse highlight, so that redisplay
3920 restores it after reallocating the glyph matrices. (Bug#7464)
3922 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
3923 string comes from a `display' text property, use the buffer
3924 position of that property as if we actually saw that position in
3925 the row's glyphs.
3926 (move_it_by_lines): Remove the assertion that
3927 "it->current_x == 0 && it->hpos == 0" which can be legitimately
3928 violated when there's a before-string at the beginning of a line.
3929 (Bug#11063)
3931 2012-03-30 Eli Zaretskii <eliz@gnu.org>
3933 * xdisp.c (append_space_for_newline): If the default face was
3934 remapped, use the remapped face for the appended newline.
3935 (extend_face_to_end_of_line): Use the remapped default face for
3936 extending the face to the end of the line.
3937 (display_line): Call extend_face_to_end_of_line when the default
3938 face was remapped. (Bug#11068)
3940 2012-03-29 Eli Zaretskii <eliz@gnu.org>
3942 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
3944 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
3946 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
3948 2012-03-27 Glenn Morris <rgm@gnu.org>
3950 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
3951 Doc fixes.
3953 2012-03-26 Kenichi Handa <handa@m17n.org>
3955 * dispextern.h (struct glyph): Fix previous change. Change the
3956 bit length of glyphless.ch to 25 (Bug#11082).
3958 2012-03-26 Chong Yidong <cyd@gnu.org>
3960 * keyboard.c (Vselection_inhibit_update_commands): New variable.
3961 (command_loop_1): Use it; inhibit selection update for
3962 handle-select-window too (Bug#8996).
3964 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
3966 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
3968 2012-03-25 Kenichi Handa <handa@m17n.org>
3970 * dispextern.h (struct glyph): Change the bit length of
3971 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
3973 2012-03-24 Eli Zaretskii <eliz@gnu.org>
3975 * s/ms-w32.h (tzname): Include time.h before redirecting to
3976 _tzname. Fixes the MSVC build. (Bug#9960)
3978 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
3980 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
3981 characters.
3983 * xterm.c (XTread_socket): Only modify handling_signal if
3984 !SYNC_INPUT. (Bug#11080)
3986 2012-03-23 Eli Zaretskii <eliz@gnu.org>
3988 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
3989 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
3990 when fetching a multibyte character consumes more bytes than
3991 CHAR_BYTES returns, due to unification of CJK characters in
3992 string_char. (Bug#11073)
3994 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
3996 * process.c (wait_reading_process_output): Handle pty disconnect
3997 by refraining from sending oneself a SIGCHLD (bug#10933).
3999 2012-03-22 Chong Yidong <cyd@gnu.org>
4001 * dispextern.h (struct it): New member string_from_prefix_prop_p.
4003 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4004 Mark string as coming from a prefix property.
4005 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4006 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4008 2012-03-21 Chong Yidong <cyd@gnu.org>
4010 * xfaces.c (Vface_remapping_alist): Doc fix.
4012 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4014 * w32proc.c (Fw32_set_console_codepage)
4015 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4016 Doc fixes.
4018 2012-03-20 Chong Yidong <cyd@gnu.org>
4020 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4021 to reflect default non-nil value of redisplay-dont-pause.
4023 2012-03-19 Kenichi Handa <handa@m17n.org>
4025 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4026 it fit in a valid range (Bug#11003).
4028 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4030 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4031 that is not from display property, accept the row as a "cursor
4032 row" if one of the string's character has a non-nil `cursor'
4033 property. Fixes cursor positioning when there are newlines in
4034 overlay strings, e.g. in icomplete.el. (Bug#11035)
4036 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4038 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4040 2012-03-12 Chong Yidong <cyd@gnu.org>
4042 * eval.c (inhibit_lisp_code): Rename from
4043 inhibit_window_configuration_change_hook; move from window.c.
4045 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4046 * window.c (run_window_configuration_change_hook)
4047 (syms_of_window): Callers changed.
4049 2012-03-11 Chong Yidong <cyd@gnu.org>
4051 * keymap.c (Fkey_description): Doc fix (Bug#9700).
4053 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
4055 2012-03-10 Chong Yidong <cyd@gnu.org>
4057 * frame.c (other_visible_frames): Don't assume the selected frame
4058 is visible (Bug#10955).
4060 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
4062 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4064 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4066 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4067 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4068 zero (Bug#10954).
4070 2012-03-03 Glenn Morris <rgm@gnu.org>
4072 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
4074 2012-03-02 Eli Zaretskii <eliz@gnu.org>
4076 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4077 position past the first glyph_row that ends at ZV. (Bug#10902)
4078 (redisplay_window, next_element_from_string): Fix typos in
4079 comments.
4080 (redisplay_window): Pass to move_it_vertically the margin in
4081 pixels, not in screen lines.
4083 2012-03-02 Glenn Morris <rgm@gnu.org>
4085 * buffer.c (buffer-list-update-hook): Doc fix.
4087 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4089 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4090 push_it before setting up the iterator for the first overlay
4091 string, even if we have an empty string loaded.
4092 (next_overlay_string): If there's an empty string on the iterator
4093 stack, pop the stack. (Bug#10903)
4095 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4097 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4098 Suggested by Stefan Monnier in
4099 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4100 * alloc.c (widen_to_Lisp_Object): New static function.
4101 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4102 and widening them to Lisp_Objects. This would work even if
4103 USE_LSB_TAG is defined and wide integers are used, which might
4104 happen in a future version of Emacs.
4106 2012-02-25 Chong Yidong <cyd@gnu.org>
4108 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4109 Doc fix.
4111 * xselect.c (Fx_selection_exists_p): Doc fix.
4112 (x_clipboard_manager_save_all): Print an informative message
4113 before saving to clipboard manager.
4115 2012-02-24 Chong Yidong <cyd@gnu.org>
4117 * keyboard.c (process_special_events): Handle all X selection
4118 requests in kbd_buffer, not just the next one (Bug#8869).
4120 2012-02-23 Chong Yidong <cyd@gnu.org>
4122 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4123 call when setting menu-bar-lines and tool-bar-lines parameters.
4124 (unwind_create_frame_1): New helper function.
4126 * window.c (inhibit_window_configuration_change_hook): New var.
4127 (run_window_configuration_change_hook): Obey it.
4128 (syms_of_window): Initialize it.
4130 2012-02-22 Chong Yidong <cyd@gnu.org>
4132 * xterm.c (x_draw_image_relief): Add missing type check for
4133 Vtool_bar_button_margin (Bug#10743).
4135 2012-02-21 Chong Yidong <cyd@gnu.org>
4137 * fileio.c (Vfile_name_handler_alist): Doc fix.
4139 * buffer.c (Fget_file_buffer): Protect against invalid file
4140 handler return value.
4142 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
4144 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4145 when computing $valmask.
4147 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4148 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4149 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4150 It's useless in that case, and it can cause problems on hosts
4151 that allocate halves of EMACS_INT values separately.
4152 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4153 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4154 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4155 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4156 it avoids undefined behavior on hosts where shifting right by more
4157 than the word width has undefined behavior.
4159 2012-02-19 Chong Yidong <cyd@gnu.org>
4161 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4162 (Funhandled_file_name_directory, Ffile_name_as_directory)
4163 (Fdirectory_file_name, Fexpand_file_name)
4164 (Fsubstitute_in_file_name): Protect against invalid file handler
4165 return values (Bug#10845).
4167 2012-02-18 Eli Zaretskii <eliz@gnu.org>
4169 * .gdbinit (pitx): Fix incorrect references to fields of the
4170 iterator stack.
4172 2012-02-17 Chong Yidong <cyd@gnu.org>
4174 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
4176 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
4178 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
4179 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
4181 2012-02-15 Chong Yidong <cyd@gnu.org>
4183 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4184 marked as special. Also, starting docstrings with * is obsolete.
4186 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
4188 * gnutls.c (emacs_gnutls_write): Fix last change.
4190 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
4192 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
4193 send_process.
4195 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
4197 * keymap.c (Fsingle_key_description): Handle char ranges.
4199 2012-02-12 Chong Yidong <cyd@gnu.org>
4201 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
4202 as that creates a dangerous corner case.
4204 * window.c (Fdelete_window_internal): Invalidate the mouse
4205 highlight (Bug#9904).
4207 2012-02-12 Glenn Morris <rgm@gnu.org>
4209 * xselect.c (Fx_own_selection_internal)
4210 (Fx_get_selection_internal, Fx_disown_selection_internal)
4211 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
4212 * nsselect.m (Fx_own_selection_internal)
4213 (Fx_disown_selection_internal, Fx_selection_exists_p)
4214 (Fx_selection_owner_p, Fx_get_selection_internal):
4215 Sync docs and argument specs with the xselect.c versions.
4217 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
4219 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
4221 2012-02-11 Eli Zaretskii <eliz@gnu.org>
4223 * w32select.c (Fx_selection_exists_p): Sync doc string and
4224 argument list with xselect.c. (Bug#10783)
4226 * w16select.c (Fx_selection_exists_p): Sync doc string and
4227 argument list with xselect.c. (Bug#10783)
4229 2012-02-10 Glenn Morris <rgm@gnu.org>
4231 * fns.c (Fsecure_hash): Doc fix.
4233 2012-02-09 Kenichi Handa <handa@m17n.org>
4235 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
4237 2012-02-07 Chong Yidong <cyd@gnu.org>
4239 * buffer.c (Fbuffer_local_variables)
4240 (buffer_lisp_local_variables): Handle unbound vars correctly;
4241 don't let Qunbound leak into Lisp.
4243 2012-02-07 Glenn Morris <rgm@gnu.org>
4245 * image.c (Fimagemagick_types): Doc fix.
4247 * image.c (imagemagick-render-type): Change it from a lisp object
4248 to an integer. Move the doc here from the lisp manual.
4249 Treat all values not equal to 0 the same.
4251 2012-02-06 Chong Yidong <cyd@gnu.org>
4253 * doc.c (store_function_docstring): Avoid applying docstring of
4254 alias to base function (Bug#2603).
4256 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
4258 * .gdbinit (pp1, pv1): Remove redundant defines.
4259 (pr): Use pp.
4261 2012-02-04 Chong Yidong <cyd@gnu.org>
4263 * nsterm.m: Declare a global (Bug#10694).
4265 2012-02-04 Eli Zaretskii <eliz@gnu.org>
4267 * w32.c (get_emacs_configuration_options):
4268 Include --enable-checking, if specified, in the return value.
4270 2012-02-04 Martin Rudalics <rudalics@gmx.at>
4272 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
4273 after rounding frame sizes. (Bug#9723)
4275 2012-02-04 Eli Zaretskii <eliz@gnu.org>
4277 * keyboard.c (adjust_point_for_property): Don't position point
4278 before BEGV. (Bug#10696)
4280 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
4282 Handle overflow when computing char display width (Bug#9496).
4283 * character.c (char_width): Return EMACS_INT, not int.
4284 (char_width, c_string_width): Check for overflow when
4285 computing the width; this is possible now that individual
4286 characters can have unbounded width. Problem introduced
4287 by merge from Emacs 23 on 2012-01-19.
4289 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
4291 * dbusbind.c (Fdbus_register_method): Mention the return value
4292 :ignore in the docstring.
4294 2012-02-02 Glenn Morris <rgm@gnu.org>
4296 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.
4298 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
4299 Unconditionally set to t. (Bug#10673)

4304 2012-02-02 Kenichi Handa <handa@m17n.org>
4306 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
4307 0, do not call append_composite_glyph.
4309 2012-02-02 Kenichi Handa <handa@m17n.org>
4311 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
4312 NULL (Bug#6988).
4313 (x_produce_glyphs): If the component of a composition is a null
4314 string, set it->pixel_width to 1 to avoid zero-width glyph.
4316 2012-02-01 Eli Zaretskii <eliz@gnu.org>
4318 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
4319 first 2 arguments are identical. This makes inserting large
4320 output from a subprocess an order of magnitude faster on
4321 MS-Windows, where all sbrk'ed memory is always contiguous.
4323 2012-01-31 Glenn Morris <rgm@gnu.org>
4325 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
4326 * w32term.c (syms_of_w32term) <x-toolkit-scroll-bars>:

4333 2012-01-28 Samuel Thibault <sthibault@debian.org> (tiny change)
4335 * s/gnu.h: Define POSIX_SIGNALS (Bug#10552).
4337 2012-01-28 Chong Yidong <cyd@gnu.org>
4339 * minibuf.c (syms_of_minibuf): Doc fix (Bug#10550).
4341 2012-01-26 Chong Yidong <cyd@gnu.org>

4361 2012-01-21 Chong Yidong <cyd@gnu.org>
4363 * floatfns.c (Fcopysign): Make the second argument non-optional,
4364 since nil is not allowed anyway.
4366 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
4368 * process.c (read_process_output): Use p instead of XPROCESS (proc).
4369 (send_process): Likewise.
4371 2012-01-19 Martin Rudalics <rudalics@gmx.at>
4373 * window.c (save_window_save, Fcurrent_window_configuration)
4374 (Vwindow_persistent_parameters): Do not use Qstate.
4375 Rewrite doc-strings.

4940 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
4941 is set, removing the need for VIRT_ADDRESS_VARIES.
4942 (PURE_P): Use a more-efficient implementation that needs just one
4943 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

4945 to 4 (xorl, subq, cmpq, setbe).
4946 * alloc.c (pure): Always extern now, since that's the
4947 VIRT_ADDR_VARIES behavior.
4948 (PURE_POINTER_P): Use a single comparison, not two, for
4949 consistency with the new puresize.h.
4950 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

4958 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
4959 behave as if the cursor position were at the window margin.
4961 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
4962 and the cursor position is out of bounds, behave as if the cursor
4963 position were at the window margin. (Bug#10075)
4965 2011-11-18 Chong Yidong <cyd@gnu.org>
4967 * window.c (Fwindow_combination_limit): Make first argument

4988 * xdisp.c (row_hash): New function, body extracted from
4989 compute_line_metrics.
4990 (compute_line_metrics): Call row_hash, instead of computing the
4991 hash code inline.
4993 * dispnew.c (verify_row_hash): Call row_hash for computing the
4994 hash code of a row, instead of duplicating code from xdisp.c.
4996 * dispextern.h (row_hash): Add prototype.
4998 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

5034 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5036 * xdisp.c (display_line): Move the call to
5037 highlight_trailing_whitespace before the call to
5038 compute_line_metrics, since the latter needs to see the final
5039 faces of all the glyphs to compute ROW's hash value.
5040 Fixes assertion violations in row_equal_p. (Bug#10035)
5042 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
5044 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

5049 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5050 with user-defined heap size. Bump the default size of the temacs
5051 heap to 27MB, to avoid memory warning when running temacs.
5052 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
5054 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

5101 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
5103 Avoid some portability problems by eschewing 'extern inline' functions.
5104 The trivial performance wins aren't worth the portability hassles; see

5110 by removing the "extern"s.
5111 * intervals.c (adjust_intervals_for_insertion)
5112 (adjust_intervals_for_deletion): Undo previous change,
5113 making these static again.
5114 (offset_intervals, temp_set_point_both, temp_set_point)
5115 (copy_intervals_to_string): No longer inline.
5116 * xdisp.c (window_text_bottom_y, window_box_width)

5181 (window_box_width, window_box_left, window_box_left_offset)
5182 (window_box_right, window_box_right_offset): Declare extern.
5183 Otherwise, these inline functions do not conform to C99 and
5184 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5185 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5186 * intervals.c (adjust_intervals_for_insertion)
5187 (adjust_intervals_for_deletion): Now extern, because otherwise the

5189 (static_offset_intervals): Remove.
5190 (offset_intervals): Rewrite using the old contents of
5191 static_offset_intervals. The old version didn't conform to C99

5264 Support MSVC build with newer versions of Visual Studio.
5265 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

5299 * xdisp.c (note_mouse_highlight): If either of
5300 previous/next-single-property-change returns nil, treat that as
5301 the beginning or the end of the buffer. (Bug#9955)

5315 2011-11-03 Eli Zaretskii <eliz@gnu.org>
5317 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
5319 * w32fns.c (unwind_create_frame): If needed, free the glyph
5320 matrices of the partially constructed frame. (Bug#9943)
5321 * xfns.c (unwind_create_frame): Likewise.
5323 2011-11-01 Eli Zaretskii <eliz@gnu.org>
5325 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
5326 Don't stop backward scan on the continuation glyph, even though
5327 its CHARPOS is positive.
5328 (mouse_face_from_buffer_pos, note_mouse_highlight):
5329 Rename cover_string to disp_string.
5331 2011-11-01 Martin Rudalics <rudalics@gmx.at>
5333 * window.c (temp_output_buffer_show): Don't use
5334 Vtemp_buffer_show_specifiers.
5335 (Vtemp_buffer_show_specifiers): Remove unused variable.
5337 2011-10-30 Eli Zaretskii <eliz@gnu.org>
5339 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
5340 past the beginning of the current glyph matrix.
5342 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
5344 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
5345 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
5346 HAVE_GTK3 (Bug#9869).
5348 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
5349 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
5351 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
5353 * xterm.c: Declare x_handle_net_wm_state to return int.
5354 (handle_one_xevent): Check if we are iconified but don't have
5355 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
5356 (get_current_wm_state): Return non-zero if not hidden,
5357 check for _NET_WM_STATE_HIDDEN (Bug#9893).
5358 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
5359 (x_handle_net_wm_state): Return what get_current_wm_state returns.
5360 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
5362 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
5364 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
5365 so that this new function doesn't get optimized away by a
5366 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
5368 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
5370 * frame.h (MOUSE_HL_INFO): Remove excess parens.
5372 2011-10-29 Eli Zaretskii <eliz@gnu.org>
5374 Fix the `xbytecode' command.
5375 * .gdbinit (xprintbytestr): New command.
5376 (xwhichsymbols): Rename from `which'; all callers changed.
5377 (xbytecode): Print the byte-code string as well.
5379 2011-10-29 Kim Storm <storm@cua.dk>
5381 * alloc.c (which_symbols): New function.
5383 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
5385 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
5386 line. (Bug#9903)
5388 2011-10-29 Glenn Morris <rgm@gnu.org>
5390 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
5391 Not clear what it was for, and it causes various bugs. (Bug#9839)
5393 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5395 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
5396 possible random value that matches one of those tested as
5397 condition to clear the mouse face.
5399 2011-10-28 Chong Yidong <cyd@gnu.org>
5401 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
5403 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
5405 * window.c (make_window): Initialize phys_cursor_on_p.
5407 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5409 * lisp.h (struct Lisp_Symbol): Update comments.
5411 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
5413 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
5415 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5417 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
5418 <oslsachem@gmail.com> for helping to debug this.
5420 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
5421 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
5422 (g_b_init_get_glyph_outline_w): New static variables.
5423 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
5424 (GetGlyphOutlineW_Proc): New typedefs.
5425 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
5426 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
5427 New functions.
5428 (w32font_open_internal, compute_metrics):
5429 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
5430 instead of calling the "wide" APIs directly.
5432 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
5434 * w32.h (syms_of_w32font): Add prototype.
5436 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5438 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
5439 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
5440 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
5441 (Fmove_to_window_line): Doc fix.
5443 2011-10-27 Chong Yidong <cyd@gnu.org>
5445 * process.c (make_process): Set gnutls_state to NULL.
5447 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
5448 non-NULL, regardless of GNUTLS_INITSTAGE.
5449 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
5450 an error. Set process slots as soon as we allocate them.
5452 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
5454 2011-10-27 Chong Yidong <cyd@gnu.org>
5456 * gnutls.c (emacs_gnutls_deinit): New function.
5457 Deallocate credentials structures as well as calling gnutls_deinit.
5458 (Fgnutls_deinit, Fgnutls_boot): Use it.
5460 * process.c (make_process): Initialize GnuTLS credentials to NULL.
5461 (deactivate_process): Call emacs_gnutls_deinit.
5463 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5465 * image.c (x_create_x_image_and_pixmap):
5466 * w32.c (sys_rename, w32_delayed_load):
5467 * w32font.c (fill_in_logfont):
5468 * w32reg.c (x_get_string_resource): Silence compiler warnings.
5470 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
5472 * w32fns.c (w32_default_color_map): New function,
5473 extracted from Fw32_default_color_map.
5474 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
5476 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
5478 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
5480 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
5482 * keyboard.c (test_undefined): New function (bug#9751).
5483 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
5485 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
5487 * sysdep.c (init_sys_modes): Fix the check for the controlling
5488 terminal (Bug#6649).
5490 2011-10-20 Eli Zaretskii <eliz@gnu.org>
5492 * dispextern.h (struct bidi_it): New member next_en_type.
5494 * bidi.c (bidi_line_init): Initialize the next_en_type member.
5495 (bidi_resolve_explicit_1): When next_en_pos is valid for the
5496 current character, check also for next_en_type being WEAK_EN.
5497 (bidi_resolve_weak): Don't enter the expensive loop if the current
5498 position is before next_en_pos. Record the bidi type of the first
5499 non-ET, non-BN character we find, in addition to its position.
5500 (bidi_level_of_next_char): Invalidate next_en_type when
5501 next_en_pos is over-stepped.
5503 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
5505 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5506 * editfns.c: Rewrite current-time-zone so that it invokes
5507 the equivalent of (format-time-string "%Z") to get the time zone name.
5508 This fixes a bug when the time zone name contains characters that
5509 need converting from the system time locale to Emacs internal format.
5510 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5511 that patch fixed format-time-string to do the conversion, but
5512 I forgot to fix current-time-zone.
5513 (format_time_string): New function, containing most of
5514 what Fformat_time_string used to contain.
5515 (Fformat_time_string): Rewrite in terms of format_time_string.
5516 This doesn't change this function's behavior.
5517 (current-time-zone): Rewrite to use format_time_string.
5518 This fixes the bug reported by Michael Schierl in
5519 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5520 Jason Rumney's 2007-06-07 change worked around this bug, but
5521 didn't fix it.
5522 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5524 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5526 * xdisp.c (start_display): If the character at POS is displayed
5527 via a display vector, reset IT->current.dpvec_index to zero.
5528 (try_window_reusing_current_matrix): If a line ends in a display
5529 vector or the next line starts in a display vector, continue
5530 redrawing the window even though the character position of
5531 start_row was reached.
5532 (Bug#9771, part 2)
5534 2011-10-18 Chong Yidong <cyd@gnu.org>
5536 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5537 with nobreak-char-display too.
5539 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5541 Fix part 3 of bug#9771.
5542 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5543 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5544 non-neutral characters if the current character is a paragraph
5545 separator (a.k.a. Newline). This avoids running the same
5546 expensive loop twice, once when we consume the preceding newline
5547 and the other time when the line actually needs to be displayed.
5548 Avoid the loop when we see neutrals on the base embedding level
5549 following a character whose directionality is the same as the
5550 paragraph's. This avoids running the expensive loop when a line
5551 ends in a long sequence of neutrals, like control characters.
5552 Add assertion against STRONG_AL type. Slightly rearrange code
5553 that determines the type of a neutral given the first non-neutral
5554 that follows it.
5555 (bidi_level_of_next_char): Set next_en_pos to zero when
5556 invalidating its info.
5558 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5560 * xdisp.c (push_display_prop): Determine whether to record string
5561 or buffer position by IT->string, not by IT->method. Allow
5562 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5563 (move_it_vertically_backward): Don't look for character position
5564 immediately after the newline when in a continuation line.
5565 (Bug#9771, part 1)
5567 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5569 * window.c (coordinates_in_window): Rewrite and delabelize
5570 vertical border check. (Bug#5357) (Bug#9618)
5572 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5574 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5575 errors in XSetWindowBorder (bug#9310).
5577 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5579 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5580 avoid crash when xmalloc overrun checking is enabled.
5582 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5584 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5585 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5586 cursor motion with <left> and <right> arrow keys.
5588 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5589 some callers set that themselves.
5591 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5593 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5594 display string and the previous row comes from the same string and
5595 is empty. (Bug#9739) (Bug#9738)
5597 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5599 * doc.c (get_doc_string): Encode file name (bug#9735).
5601 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5603 * bidi.c (bidi_level_of_next_char):
5604 * xdisp.c (get_visually_first_element): Remove old incorrect
5605 comments regarding the Unicode Line Separator character.
5607 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5609 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5611 * alloc.c (Fgc_status): Do not access beyond zombies array
5612 boundary if nzombies > MAX_ZOMBIES.
5613 * alloc.c (dump_zombies): Add missing format specifier.
5615 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5617 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5618 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5620 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5621 Some packages use them to denote characters with modifiers.
5623 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5625 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5626 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5627 matching a pp-number. Rename parameter var to var1.
5629 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5631 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5633 2011-10-08 Glenn Morris <rgm@gnu.org>
5635 * callint.c (Fcall_interactively): Give a more explicit error for the
5636 'c' case with a non-character input. (Bug#8479)
5638 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5640 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5641 lines.
5642 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5643 lines that are hscrolled on the left.
5645 * dispnew.c (buffer_posn_from_coords): Account for a possible
5646 presence of header-line. (Bug#4426)
5648 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5650 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5651 Don't advertise functionality which we discourage or doesn't work.
5653 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5655 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5656 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5657 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5658 this makes Emacs dump core during garbage collection on rare
5659 occasions. sizeof is obviously inferior to offsetof here, so
5660 stick with offsetof.
5661 (GC_POINTER_ALIGNMENT): New macro.
5662 (mark_memory): Omit 3rd (offset) arg; caller changed.
5663 Don't assume EMACS_INT alignment is the same as pointer alignment.
5665 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5667 * keyboard.c (read_key_sequence_remapped): New var.
5668 (read_key_sequence): Compute remapping in the right buffer.
5669 (command_loop_1): Use read_key_sequence's remapping directly.
5671 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5673 * dired.c (file_name_completion): Don't expand file name.
5674 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5675 before checking file name handler.
5677 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5678 they've been requested explicitly (bug#9591).
5680 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5682 * keymap.c (Fsingle_key_description): Use make_specified_string
5683 instead of build_string to build string from push_key_description.
5684 (Bug#5193)
5686 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5688 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5689 This fixes a Y2038 bug on 64-bit hosts.
5690 * buffer.c (reset_buffer):
5691 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5692 (Fclear_buffer_auto_save_failure):
5693 Use 0, not -1, to represent an unset failure time, since time_t
5694 might not be signed.
5696 Remove dependency on glibc malloc internals.
5697 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5698 Move back here from lisp.h, but with their new implementations.
5699 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5700 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5701 * charset.c (charset_table_init): New static var.
5702 (syms_of_charset): Use it instead of xmalloc. This removes a
5703 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5704 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
5705 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5706 Move back to alloc.c.
5707 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5708 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
5710 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
5712 * nsterm.m (windowDidResize): Call x_set_window_size only when
5713 ns_in_resize is true. Otherwise set pixelwidth/height and
5714 call change_frame_size (Bug#9628).
5716 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5718 Port --enable-checking=all to Fedora 14 x86-64.
5719 * charset.c (syms_of_charset): Also account for glibc malloc's
5720 internal overhead when calculating the initial malloc maximum.
5722 Port --enable-checking=all to Fedora 14 x86.
5723 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5724 Move to lisp.h.
5725 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5726 (overrun_check_realloc, overrun_check_free):
5727 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5728 That way, xmalloc returns a properly-aligned pointer even if
5729 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
5730 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5731 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5732 into account when calculating the initial malloc maximum.
5733 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5734 Move here from alloc.c, so that charset.c can use it too.
5735 Properly align; the old code wasn't right for common 32-bit hosts
5736 when configured with --enable-checking=all.
5737 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5738 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
5740 2011-09-29 Eli Zaretskii <eliz@gnu.org>
5742 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
5743 use EDOM.
5745 2011-09-28 Eli Zaretskii <eliz@gnu.org>
5747 * xdisp.c (compute_display_string_end): If there's no display
5748 string at CHARPOS, return -1.
5750 * bidi.c (bidi_fetch_char): When compute_display_string_end
5751 returns a negative value, treat the character as a normal
5752 character not covered by a display string. (Bug#9624)
5754 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
5756 * lread.c (Fread_from_string): Fix typo in docstring.
5758 2011-09-27 Eli Zaretskii <eliz@gnu.org>
5760 * xdisp.c (handle_invisible_prop): If invisible text ends on a
5761 newline, reseat the iterator instead of bidi-iterating there one
5762 character at a time. (Bug#9610)
5763 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
5764 TO_CHARPOS if the bidi iterator is at base embedding level.
5766 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
5768 * lread.c (readevalloop): Use correct code for NBSP.
5769 (read1): Likewise. (Bug#9608)
5771 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
5773 * dbusbind.c (Fdbus_register_signal): When service is not
5774 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
5776 2011-09-25 Glenn Morris <rgm@gnu.org>
5778 * buffer.c (truncate-lines): Doc fix.
5780 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
5782 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
5783 (Fset_window_next_buffers): Doc fix.
5785 2011-09-24 Glenn Morris <rgm@gnu.org>
5787 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
5789 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
5791 Fix minor problems found by static checking.
5792 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
5793 * indent.c (Fvertical_motion): Fix == vs = typo.
5795 2011-09-24 Eli Zaretskii <eliz@gnu.org>
5797 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
5798 Default value is now t. Doc fix.
5800 * indent.c (Fvertical_motion): Compute and apply the overshoot
5801 logic when moving up, not only when moving down. Fix the
5802 confusing name and values of the it_overshoot_expected variable;
5803 logic changes accordingly. (Bug#9254) (Bug#9549)
5805 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
5806 CHARPOS is covered by a display string which includes newlines.
5807 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
5808 is covered by a display string with embedded newlines.
5810 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
5812 * dbusbind.c (Fdbus_register_signal): Add match rule to
5813 Vdbus_registered_objects_table. (Bug#9581)
5814 (Fdbus_register_method, Vdbus_registered_objects_table):
5815 Fix docstring.
5817 2011-09-24 Jim Meyering <meyering@redhat.com>
5819 do not ignore write error for any output size
5820 The previous change was incomplete.
5821 While it makes emacs --batch detect the vast majority of stdout
5822 write failures, errors were still ignored whenever the output size is
5823 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
5824 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
5825 && echo FAIL: ignored write error
5826 FAIL: ignored write error
5827 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
5828 && echo FAIL: ignored write error
5829 FAIL: ignored write error
5830 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
5832 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
5834 * emacs.c (Fkill_emacs): In noninteractive mode exit
5835 non-successfully if a write error occurred on stdout. (Bug#9574)
5837 2011-09-21 Eli Zaretskii <eliz@gnu.org>
5839 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
5840 the xassert test.
5842 * dispextern.h (struct it): Update the comment documenting what
5843 can it->OBJECT be.
5845 2011-09-20 Eli Zaretskii <eliz@gnu.org>
5847 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
5848 a display string, extend search for cursor position to end of row.
5849 (find_row_edges): If the row ends in a newline from a display
5850 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
5851 Handle the case of a display string with multiple newlines.
5852 (Fcurrent_bidi_paragraph_direction): Fix search for previous
5853 non-empty line. Fixes confusing cursor motion with arrow keys at
5854 the beginning of a line that starts with whitespace.
5856 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
5858 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
5859 (bug#9493).
5861 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
5863 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
5864 boolean (Bug#9154).
5866 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5868 * xdisp.c (display_line): Record maximum and minimum buffer
5869 positions even if no glyphs were produced (e.g., by a zero-width
5870 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
5871 buffer positions that will be removed from the glyph row because
5872 they don't fit.
5873 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
5874 column is beyond frame width: don't subtract 1 "pixel" when
5875 computing width of the stretch.
5876 (reseat_at_next_visible_line_start): Undo the change made on
5877 2011-09-17 that saved paragraph information and restored it after
5878 the call to `reseat'. (Bug#9545)
5880 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5882 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
5883 and turn window cursor on if cleared (Bug#9415).
5885 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
5887 * search.c (boyer_moore): Take unibyte characters from pattern
5888 literally. (Bug#9458)
5890 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5892 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
5894 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
5896 Fix minor problem found by static checking.
5897 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
5898 initialized, to pacify gcc -Wuninitialized.
5900 * fileio.c: Report proper errno when syscall falls.
5901 (Finsert_file_contents): Save and restore errno,
5902 so that report_file_error outputs the correct diagnostic.
5903 (Fwrite_region) [CLASH_DETECTION]: Likewise.
5905 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5907 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
5909 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5911 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
5912 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
5914 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5916 * xdisp.c (reseat_at_next_visible_line_start): Keep information
5917 about the current paragraph and restore it after the call to reseat.
5919 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
5920 (bidi_find_paragraph_start): Search back for paragraph beginning
5921 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
5922 (bidi_move_to_visually_next): Only trigger paragraph-related
5923 computations when the last character is a newline or at EOB, not
5924 just any NEUTRAL_B. (Bug#9470)
5926 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
5927 truncated lines if point is covered by a display string. (Bug#9524)
5929 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
5931 * xselect.c: Relax test for outgoing X longs (Bug#9498).
5932 (cons_to_x_long): New function.
5933 (lisp_data_to_selection_data): Use it. Correct the test for
5934 short-versus-long data; it was negated. Break out of vector
5935 loop, for efficiency, when a long datum is discovered.
5937 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
5939 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
5941 2011-09-16 Eli Zaretskii <eliz@gnu.org>
5943 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
5944 GCC PR/17406) by declaring this function with external scope.
5946 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5948 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
5949 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
5951 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
5953 * editfns.c (Fformat): Correctly handle text properties on "%%".
5955 2011-09-15 Eli Zaretskii <eliz@gnu.org>
5957 * xterm.c (x_draw_composite_glyph_string_foreground):
5958 * w32term.c (x_draw_composite_glyph_string_foreground):
5959 * term.c (encode_terminal_code):
5960 * composite.c (composition_update_it, get_composition_id):
5961 * xdisp.c (get_next_display_element)
5962 (fill_composite_glyph_string): Add comments about special meaning
5963 of TAB characters in a composition.
5965 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5967 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
5968 This occurs when processing a multibyte format.
5969 Problem reported by Wolfgang Jenker.
5971 2011-09-15 Johan Bockgård <bojohan@gnu.org>
5973 * xdisp.c (try_cursor_movement): Only check for exact match if
5974 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
5976 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5978 Remove unused external symbols.
5979 * dispextern.h (calc_pixel_width_or_height): Remove decl.
5980 * xdisp.c (calc_pixel_width_or_height): Now static.
5981 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
5982 * indent.c (check_display_width):
5983 * w32term.c: Fix comment to match code.
5984 * xterm.c, xterm.h (x_catching_errors): Remove.
5986 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5988 * xselect.c: Use signed conversions more consistently (Bug#9498).
5989 (selection_data_to_lisp_data): Assume incoming selection data are
5990 signed integers, not unsigned. This is to be consistent with
5991 outgoing selection data, which was modified to use signed integers
5992 in as part of the fix to Bug#9196 in response to Jan D.'s comment
5993 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
5994 expects long, not unsigned long.
5996 2011-09-14 Eli Zaretskii <eliz@gnu.org>
5998 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
5999 computation of loop end. Reported by Johan Bockgård
6000 <bojohan@gnu.org>.
6002 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6004 * frame.c (Fother_visible_frames_p): Function deleted.
6006 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6008 * indent.c (compute_motion): Process display vector front to back
6009 rather than the other way around. (Bug#2496)
6011 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6013 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6015 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6017 * minibuf.c (Fread_from_minibuffer): Doc fix.
6019 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6021 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6022 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6024 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6026 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6027 value for non-existent files.
6029 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6031 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6032 set its "size" to -1. This will set the modtime_size field of
6033 the corresponding buffer to -1, which is what
6034 verify-visited-file-modtime expects for files that do not exist.
6035 (Bug#9139)
6037 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6039 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6040 here ...
6041 * lisp.h: ... from here. push_key_description is no longer
6042 defined in keyboard.c, so its declaration should not be in
6043 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6044 logically belongs with push_key_description.
6046 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6048 * buffer.h: Include <sys/types.h> instead of <time.h>.
6049 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6050 Problem reported by Herbert J. Skuhra.
6052 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6054 * xml.c (parse_region): Make the parsing work for
6055 non-comment-starting XML files again (bug#9144).
6057 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6059 * image.c (gif_load): Fix calculation of bottom and right corner.
6060 (Bug#9468)
6062 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6064 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6065 redisplay in small windows.
6067 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6069 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6071 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6073 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6074 Operate on live windows only.
6076 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6078 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6080 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6082 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6083 only under bidi iteration.
6085 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6087 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6089 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6091 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6092 Without this fix, the command to link temacs failed due to an
6093 undefined symbol __builtin_isnan. This is because
6094 /usr/include/iso/math_c99.h #defines isnan(x) to
6095 __builtin_isnan(x), but the bundled gcc, which identifies itself
6096 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6097 a __builtin_isnan.
6098 * floatfns.c (isnan): #undef, and then #define to a clone of
6099 what's in data.c.
6100 (Fisnan): Always define, since it's always available now.
6101 (syms_of_floatfns): Always define isnan at the Lisp level.
6103 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6105 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6107 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6109 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6110 The previous code assumed that file offsets (off_t values) fit in
6111 EMACS_INT variables, which is not true on typical 32-bit hosts.
6112 The code messed up by falsely reporting buffer overflow in cases
6113 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6114 when "big" contains more than 2**29 bytes, even though this
6115 inserts just one byte and does not overflow the buffer.
6116 (Finsert_file_contents): Store file offsets as off_t
6117 values, not as EMACS_INT values. Check for overflow when
6118 converting between EMACS_INT and off_t. When checking for
6119 buffer overflow or for overlap, take the offsets into account.
6120 Don't use EMACS_INT for small values where int suffices.
6121 When checking for overlap, fix a typo: ZV was used where
6122 ZV_BYTE was intended.
6123 (Fwrite_region): Don't assume off_t fits into 'long'.
6124 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6126 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6128 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6130 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6132 sprintf-related integer and memory overflow issues (Bug#9412).
6134 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6135 (esprintf, exprintf, evxprintf): New functions.
6136 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6137 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6138 (modify_event_symbol): Do not assume that the length of
6139 name_alist_or_stem is safe to alloca and fits in int.
6140 (Fexecute_extended_command): Likewise for function name and binding.
6141 (Frecursion_depth): Wrap around reliably on integer overflow.
6142 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6143 since some callers pass EMACS_INT values.
6144 (Fsingle_key_description): Don't crash if symbol name contains more
6145 than MAX_ALLOCA bytes.
6146 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6147 (get_minibuffer): Arg is now EMACS_INT, not int.
6148 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6149 (esprintf, exprintf, evxprintf): New decls.
6150 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6152 * dbusbind.c (signature_cat): New function.
6153 (xd_signature, Fdbus_register_signal):
6154 Do not overrun buffer; instead, report string overflow.
6156 * dispnew.c (add_window_display_history): Don't overrun buffer.
6157 Truncate instead; this is OK since it's just a log.
6159 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6160 even if the time zone offset is outlandishly large.
6161 Don't mishandle offset == INT_MIN.
6163 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6164 when creating daemon; the previous buffer-overflow check was incorrect.
6166 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6167 which has the guts of the old verror function.
6169 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6170 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6172 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6173 (font_unparse_xlfd): Don't blindly alloca long strings.
6174 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6175 fits in int, when using sprintf. Use single snprintf to count
6176 length of string rather than counting it via multiple sprintfs;
6177 that's simpler and more reliable.
6178 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6179 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6180 sprintf, in case result does not fit in int.
6182 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6183 (fontset_from_font): Print it.
6185 * frame.c (tty_frame_count): Now printmax_t, not int.
6186 (make_terminal_frame, set_term_frame_name): Print it.
6187 (x_report_frame_params): In X, window IDs are unsigned long,
6188 not signed long, so print them as unsigned.
6189 (validate_x_resource_name): Check for implausibly long names,
6190 and don't assume name length fits in 'int'.
6191 (x_get_resource_string): Don't blindly alloca invocation name;
6192 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6193 not fit in int.
6195 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6196 (xg_check_special_colors, xg_set_geometry):
6197 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6199 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6200 Use esprintf, not sprintf, in case result does not fit in int.
6202 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6203 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6204 it as a large positive number.
6205 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6206 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6208 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6209 in case result does not fit in int.
6211 * print.c (float_to_string): Detect width overflow more reliably.
6212 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6213 buffer overrun. Don't assume list length fits in 'int'. Treat
6214 print length of 0 as 0, not as infinity; to be consistent with other
6215 uses of print length in this function. Don't overflow print length
6216 index. Don't assume hash table size fits in 'long', or that
6217 vectorlike size fits in 'unsigned long'.
6219 * process.c (make_process): Use printmax_t, not int, to format
6220 process-name gensyms.
6222 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6224 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6225 to avoid potential buffer overrun.
6227 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6228 if X resource line is longer than 512 bytes.
6230 * xfns.c (x_window): Make sprintf buffer a bit bigger
6231 to avoid potential buffer overrun.
6233 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6235 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6237 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6239 Integer overflow fixes for scrolling, etc.
6240 Without these, Emacs silently mishandles large integers sometimes.
6241 For example, "C-u 4294967297 M-x recenter" was treated as if
6242 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6244 * xdisp.c (try_window_id): Check Emacs fixnum range before
6245 converting to 'int'.
6247 * window.c (window_scroll_line_based, Frecenter):
6248 Check that an Emacs fixnum is in range before assigning it to 'int'.
6249 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6250 values converted from Emacs fixnums.
6251 (Frecenter): Don't wrap around a line count if it is out of 'int'
6252 range; instead, treat it as an extreme value.
6253 (Fset_window_configuration, compare_window_configurations):
6254 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6256 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6257 that can exceed INT_MAX. Check that EMACS_INT value is in range
6258 before assigning it to the (possibly-narrower) index.
6259 (match_limit): Don't assume that a fixnum can fit in 'int'.
6261 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6262 exceed INT_MAX.
6264 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6265 (Fvertical_motion): Don't wrap around LINES values that don't fit
6266 in 'int'. Instead, treat them as extreme values. This is good
6267 enough for windows, which can't have more than INT_MAX lines anyway.
6269 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6271 * Require libxml/parser.h to avoid compilation warning.
6273 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6275 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6276 since this reportedly can destroy thread storage.
6278 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6280 * syntax.c (find_defun_start): Update all cache variables if
6281 exiting early (Bug#9401).
6283 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6285 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6287 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6288 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6289 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6291 * term.c (tty_append_glyph): New function.
6292 (produce_stretch_glyph): Static function and its prototype deleted.
6294 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6295 Add prototypes.
6297 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6299 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6300 when checking :margin (Bug#9390).
6301 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6302 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6303 so that the name doesn't mislead. All uses changed.
6305 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6307 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6308 set_tty_hooks.
6310 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6312 * xdisp.c (move_it_to): Don't bail out early when reaching
6313 position beyond to_charpos, if we are scanning backwards.
6314 (move_it_vertically_backward): When DY == 0, make sure we get to
6315 the first character in the line after the newline.
6317 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6319 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6320 (ccl_driver): Do not generate an out-of-range pointer.
6321 (Fccl_execute_on_string): Remove unnecessary check for
6322 integer overflow, noted by Stefan Monnier in
6323 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6324 Remove a FIXME that didn't need fixing.
6325 Simplify the newly-introduced buffer reallocation code.
6327 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6329 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6331 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6333 Integer and memory overflow issues (Bug#9196).
6335 * doc.c (get_doc_string): Rework so that
6336 get_doc_string_buffer_size is the actual buffer size, rather than
6337 being 1 less than the actual buffer size; this makes xpalloc more
6338 convenient.
6340 * image.c (x_allocate_bitmap_record, cache_image):
6341 * xselect.c (Fx_register_dnd_atom):
6342 Simplify previous changes by using xpalloc.
6344 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6345 since either will do and ptrdiff_t is convenient with xpalloc.
6347 * charset.c (charset_table_size)
6348 (struct charset_sort_data.priority): Now ptrdiff_t.
6349 (charset_compare): Don't overflow if priorities differ greatly.
6350 (Fsort_charsets): Don't assume list length fits in int.
6351 Check for size-calculation overflow when allocating sort data.
6352 (syms_of_charset): Allocate an initial charset table that is
6353 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6355 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6357 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6358 The actual value is always <= INT_MAX, and leaving it unsigned made
6359 overflow checking harder.
6361 * dispextern.h (struct glyph_matrix.rows_allocated)
6362 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6363 with xpalloc. The values are still always <= INT_MAX.
6365 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6367 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6368 (SAFE_NALLOCA): New macro.
6370 * region-cache.c (struct boundary.pos, find_cache_boundary)
6371 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6372 (set_cache_region, invalidate_region_cache)
6373 (revalidate_region_cache, know_region_cache, region_cache_forward)
6374 (region_cache_backward, pp_cache):
6375 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6376 so that ptrdiff_t * can be passed to xpalloc.
6377 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6378 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6379 (pp_cache): Don't assume cache_len fits in int.
6380 * region-cache.h: Adjust extern decls to match.
6382 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6383 EMACS_INT, since either will do, for xpalloc.
6385 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6386 (xnmalloc, xnrealloc, xpalloc): New functions.
6388 * bidi.c (bidi_shelve_header_size): New constant.
6389 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6390 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6392 * bidi.c (bidi_cache_shrink):
6393 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6394 (overlay_strings):
6395 Don't update size of array until after memory allocation succeeds,
6396 because xmalloc/xrealloc may not return.
6397 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6398 now that we have proper integer overflow checking.
6399 (record_overlay_string, overlay_strings): Catch overflows when
6400 calculating size of overlay_str_buf.
6402 * callproc.c (Fcall_process): Check for size overflow when
6403 calculating size of args2.
6404 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6405 Normally we prefer signed values, but sticking with ptrdiff_t would
6406 require adding more-complicated checks.
6408 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6409 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6410 Redo buffer-overflow calculations to avoid integer overflow.
6411 Add a FIXME comment where memory seems to be over-allocated.
6413 * character.c (Fstring): Check for size-calculation overflow.
6415 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6416 unnecessary integer overflow. Check for size overflow.
6417 (encode_coding_object): Don't update size until xmalloc succeeds.
6419 * composite.c (get_composition_id): Check for overflow in glyph
6420 length calculations.
6422 Integer and memory overflow fixes for display code.
6423 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
6424 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6425 (scrolling_window): Check for overflow in size calculations.
6426 (line_draw_cost, realloc_glyph_pool, add_row_entry):

6429 (row_table_size): Now ptrdiff_t, not int.
6430 (scrolling_window): Avoid overflow in size calculations.

6438 (get_doc_string): Check for size calculation overflow.
6439 Don't update size until allocation succeeds.
6440 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
6441 EMACS_INT, where ptrdiff_t will do.
6442 (Fsubstitute_command_keys): Check for string overflow.
6444 * editfns.c (set_time_zone_rule): Don't assume environment length
6445 fits in int.
6446 (message_length): Now ptrdiff_t, not int.
6447 (Fmessage_box): Don't update size until allocation succeeds.
6448 Don't assume message length fits in int.
6449 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6451 * emacs.c (main): Do not reallocate argv, since there is a null at
6452 the end that can be overwritten, and this way there's no need to
6453 worry about size-calculation overflow.
6454 (sort_args): Check for size-calculation overflow.
6456 * eval.c (init_eval_once, grow_specpdl): Don't update size until
6457 alloc succeeds.
6458 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
6460 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
6461 (x_set_scroll_bar_width, x_figure_window_size):
6462 Check for integer overflow.
6463 (x_set_alpha): Do not assume XINT fits in int.
6465 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6466 This is for the members text_lines, text_cols, total_lines, total_cols,
6467 where the system imposes an 'int' limit.
6469 * fringe.c (Fdefine_fringe_bitmap):
6470 Don't update size until alloc works.
6472 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
6473 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
6475 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
6476 Check for size-calculation overflow.
6477 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6478 do, as we prefer signed integers.
6479 (id_to_widget.max_size, id_to_widget.used)
6480 (xg_store_widget_in_map, xg_remove_widget_from_map)
6481 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
6482 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
6483 Use and return ptrdiff_t, not int.
6484 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
6485 * gtkutil.h: Change prototypes to match the above.
6487 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
6488 are duplicate now that they've been promoted to lisp.h.
6489 (x_allocate_bitmap_record, x_alloc_image_color)
6490 (make_image_cache, cache_image, xpm_load):
6491 Don't update size until alloc is done.
6492 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
6493 (x_detect_edges):
6494 Check for size calculation overflow.
6495 (ct_colors_allocated_max): New constant.

6500 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
6501 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
6502 Use ptrdiff_t, not int, to count maps.
6503 (read_char_minibuf_menu_prompt): Check for overflow in size
6504 calculations. Don't update size until allocation succeeds.
6505 Redo calculations to avoid overflow.
6506 * keyboard.h: Change prototypes to match the above.

6513 * lread.c (read1, init_obarray): Don't update size until alloc done.
6515 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
6516 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.

6531 * search.c (Freplace_match): Check for size calculation overflow.
6532 (Fset_match_data): Don't assume list lengths fit in 'int'.
6534 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
6535 for command line length. Do not attempt to address one before the
6536 beginning of an array, as that's not portable.
6538 * term.c (max_frame_lines): Remove; unused.
6539 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
6540 not int.

6542 calculation overflow.
6543 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
6544 table lengths and related sizes. Don't update size until alloc
6545 done. Redo calculations to avoid overflow.
6546 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
6548 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
6549 subtracting pointers.

6564 Use ptrdiff_t, not int, for sizes.
6565 (Finternal_make_lisp_face, cache_face):
6566 Check for size calculation overflow.
6567 (cache_face): Treat size calculation overflows as if they were
6568 memory exhaustion (the usual treatment), rather than aborting.
6570 * xfns.c (x_encode_text, x_set_name_internal)
6571 (Fx_change_window_property): Use ptrdiff_t, not int, to count
6572 sizes, since they can exceed INT_MAX in size. Check for size

6576 (xg_select): Check for size calculation overflow.
6577 Don't update size until alloc done.
6579 * xrdb.c (get_environ_db): Don't assume path length fits in int,
6580 as sprintf is limited to int lengths.
6582 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
6583 (X_LONG_MIN): New macros.
6584 Use them to make the following changes clearer.
6585 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6586 This change doesn't affect the value now, but it may help remind
6587 future maintainers not to raise the value too much later.
6588 (SELECTION_QUANTUM): Remove, replacing with ...
6589 (selection_quantum): ... new function, which avoids overflow.
6590 All uses changed.
6591 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
6592 assumption that selection length fits in 'int'.
6593 (x_reply_selection_request, x_handle_selection_request)
6594 (x_get_window_property, receive_incremental_selection)
6595 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
6596 (lisp_data_to_selection_data, clean_local_selection_data):
6597 Use ptrdiff_t, not int, to record length of selection.
6598 (x_reply_selection_request, x_get_window_property)

6600 Redo calculations to avoid overflow.
6601 (x_reply_selection_request): When sending hint, ceiling it at
6602 X_LONG_MAX rather than relying on wraparound overflow to send
6603 something.
6604 (x_get_window_property, receive_incremental_selection)
6605 (lisp_data_to_selection_data, x_property_data_to_lisp):
6606 Check for size-calculation overflow.
6607 (x_get_window_property, receive_incremental_selection)
6608 (lisp_data_to_selection_data, Fx_register_dnd_atom):
6609 Don't store size until memory allocation succeeds.
6610 (x_get_window_property): Plug memory leak on memory exhaustion.
6611 Don't double-block input; malloc is safe here. Don't assume 2**34
6612 - 4 fits in unsigned long. Add an xassert to check
6613 XGetWindowProperty overflow. Be more careful about overflow
6614 calculations, and distinguish size from memory overflow better.
6615 (receive_incremental_selection): When tracing, don't assume
6616 unsigned int is less than INT_MAX.
6617 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
6618 harmful) conversions of unsigned short to int.
6619 (lisp_data_to_selection_data): Don't assume that integers
6620 in the range -65535 through -1 fit in an X unsigned short.
6621 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
6622 result parameters unless successful. Rely on cons_to_unsigned
6623 to report problems with elements; the old code wasn't right anyway.
6624 (x_check_property_data): Check for int overflow; we cannot use
6625 a wider type due to X limits.
6626 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
6628 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

6634 Don't assume alloca size is less than MAX_ALLOCA.
6635 (x_term_init): Don't assume length fits in int (sprintf is limited
6636 to int size).
6638 Use ptrdiff_t for composition IDs.
6639 * character.c (lisp_string_width):
6640 * composite.c (composition_table_size, n_compositions)

6657 * image.c (xpm_get_color_table_h):
6658 * lisp.h (hash_lookup, hash_put):
6659 * minibuf.c (Ftest_completion):
6660 Use ptrdiff_t for hash table indexes, not int (which is too
6661 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
6662 32-bit --with-wide-int hosts).
6664 * charset.c (Fdefine_charset_internal): Check for integer overflow.
6665 Add a FIXME comment about memory leaks.
6666 (syms_of_charset): Don't assume xmalloc returns.
6668 Don't assume that stated character widths fit in int.
6669 * character.c (Fchar_width, c_string_width, lisp_string_width):
6670 * character.h (CHAR_WIDTH):
6671 * indent.c (MULTIBYTE_BYTES_WIDTH):
6672 Use sanitize_char_width to avoid undefined and/or bad behavior
6673 with outlandish widths.
6674 * character.h (sanitize_tab_width): Rename from sanitize_width,
6675 now that we have two such functions. All uses changed.
6676 (sanitize_char_width): New inline function.
6678 Don't assume that tab-width fits in int.
6679 * character.h (sanitize_width): New inline function.
6680 (SANE_TAB_WIDTH): New macro.

6683 SANE_TAB_WIDTH (current_buffer).
6684 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
6686 * fileio.c: Integer overflow issues with file modes.
6687 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
6689 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
6690 Remove unreachable code.
6691 (read_hex, load_charset_map_from_file): Check for integer overflow.
6693 * xterm.c: Don't go over XClientMessageEvent limit.
6694 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
6695 (x_send_scroll_bar_event): Likewise. Check that the size does not
6696 exceed limits imposed by XClientMessageEvent, as well as the usual
6697 ptrdiff_t and size_t limits.
6699 * keyboard.c: Overflow, signedness and related fixes.
6700 (make_lispy_movement): Use same integer type in forward decl
6701 that is used in the definition.
6702 (read_key_sequence, keyremap_step):
6703 Change bufsize argument back to int, undoing my 2011-03-30 change.
6704 We prefer signed types, and int is wide enough here.
6705 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6706 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
6707 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
6708 length, not size_t. Use ptrdiff_t for index, not int.
6709 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
6710 possibility of integer overflow.
6712 Overflow, signedness and related fixes for images.
6714 * dispextern.h (struct it.stack[0].u.image.image_id)
6715 (struct_it.image_id, struct image.id, struct image_cache.size)
6716 (struct image_cache.used, struct image_cache.ref_count):

6721 * nsmenu.m (update_frame_tool_bar):
6722 * xdisp.c (calc_pixel_width_or_height):
6723 * xfns.c (image_cache_refcount):
6724 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
6725 on typical 64-bit hosts.
6727 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
6728 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

6731 when the callers expect that.
6732 (image_ascent): Redo ascent calculation to avoid int overflow.
6733 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
6734 (lookup_image): Remove unnecessary tests.
6735 (xbm_image_p): Locals are now of int, not EMACS_INT,
6736 since parse_image_check makes sure they fit into int.
6737 (png_load, gif_load, svg_load_image):
6738 Prefer int to unsigned where either will do.
6739 (tiff_handler): New function, combining the cores of the
6740 old tiff_error_handler and tiff_warning_handler.
6741 This function is rewritten to use vsnprintf and thereby avoid
6742 stack buffer overflows. It uses only the features of vsnprintf
6743 that are common to both POSIX and native Microsoft.
6744 (tiff_error_handler, tiff_warning_handler): Use it.
6745 (tiff_load, gif_load, imagemagick_load_image):
6746 Don't assume :index value fits in 'int'.
6747 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
6748 (imagemagick_load_image): Check that crop parameters fit into
6749 the integer types that MagickCropImage accepts. Don't assume
6750 Vimagemagick_render_type has a nonnegative value. Don't assume
6751 size_t fits in 'long'.
6752 (gs_load): Use printmax_t to print the widest integers possible.
6753 Check for integer overflow when computing image height and width.
6755 2011-08-26 Eli Zaretskii <eliz@gnu.org>

6762 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
6763 the display spec is of the form `(space ...)'.
6764 (handle_display_spec): Return the value returned by
6765 handle_single_display_spec, not just 1 or zero.
6766 (handle_single_display_spec): If the display spec is of the form
6767 `(space ...)', and specifies display in the text area, return 2
6768 rather than 1.
6769 (try_cursor_movement): Check for the need to scroll more
6770 accurately, and prefer exact match for point under bidi.
6771 Don't advance `row' beyond the last row of the window.
6773 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
6774 into disp_prop; all users changed.
6776 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
6777 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
6778 for the text covered by the display property.
6780 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
6782 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

6788 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
6789 buffers, return left-to-right.
6790 (set_cursor_from_row): Consider candidate row a win if its glyph
6791 represents a newline and point is on that newline. Fixes cursor
6792 positioning on the newline at EOL of R2L text within L2R
6793 paragraph, and vice versa.
6794 (try_cursor_movement): Check continued rows, in addition to
6795 continuation rows. Fixes unwarranted scroll when point enters a
6796 continued line of R2L text within an L2R paragraph, or vice versa.
6797 (cursor_row_p): Consider the case of point being equal to
6798 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
6799 from the end of a short line to the beginning of a continued line
6800 of R2L text within L2R paragraph.
6801 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
6802 composed characters.

6811 a character.
6813 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
6815 * nsfont.m (ns_otf_to_script): Fix typo.
6817 2011-08-22 Kenichi Handa <handa@m17n.org>
6819 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
6820 extra slot even if the purpose is char-code-property-table.
6822 2011-08-23 Eli Zaretskii <eliz@gnu.org>
6824 * xdisp.c (redisplay_window): When computing centering_position,
6825 account for the height of the header line. (Bug#8874)
6827 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
6828 instead of CHAR_TO_BYTE. Fixes a crash when a completion
6829 candidate is selected by the mouse, and that candidate has a
6830 composed character under the mouse.
6832 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
6833 coordinates reported by pos-visible-in-window-p for a composed
6834 character in column zero.
6836 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
6838 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
6840 2011-08-22 Eli Zaretskii <eliz@gnu.org>
6842 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
6843 consider it a hit if to_charpos is anywhere in the range of the
6844 composed buffer positions.
6846 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
6848 * image.c (gif_load): Don't assume that each subimage has the same
6849 dimensions as the base image. Handle disposal method that is
6850 "undefined" by the gif spec (Bug#9335).
6852 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
6854 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
6855 (Fcondition_case): Document `debug' symbol in error handler.
6857 2011-08-19 Eli Zaretskii <eliz@gnu.org>
6859 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
6860 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
6861 from an Org mode buffer to a Speedbar frame.
6863 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
6864 a composition, take its buffer position from IT->cmp_it.charpos.
6865 Fixes cursor positioning at the beginning of a line that begins
6866 with a composed character.
6868 2011-08-18 Eli Zaretskii <eliz@gnu.org>
6870 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
6871 character bidirectional type, use STRONG_L instead. Fixes crashes
6872 in a buffer produced by `describe-categories'.
6874 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
6875 members before the level stack, so they would be saved and
6876 restored when copying iterator state. Fixes incorrect reordering
6877 around TABs covered by display properties.
6879 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
6881 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

6889 2011-08-17 Eli Zaretskii <eliz@gnu.org>
6891 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
6892 has no `load' handler, try opening the file locally. (Bug#9311)
6894 2011-08-16 Ken Brown <kbrown@cornell.edu>
6896 * gmalloc.c: Expand comment.
6898 2011-08-16 Eli Zaretskii <eliz@gnu.org>

6951 * xdisp.c (move_it_in_display_line_to): Don't invoke
6952 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
6953 ppos_it. Fixes vertical cursor motion when line beginning is
6954 covered by an image. (Bug#9296)
6956 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
6958 * nsterm.h (ns_run_ascript): Declare.

6962 (ns_run_ascript): New function.
6963 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
6964 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
6965 the event loop. Get status from as_status (Bug#7276).
6967 * nsterm.m (sendEvent): If event is NSApplicationDefined and
6968 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
6969 the event loop (Bug#7276).
6971 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

6995 (Fnetwork_interface_list): Allocate in increments of bytes instead
6996 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
6997 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
6998 sockaddr.
6999 (struct ifflag_def): notrailers is smart on OSX.
7000 (Fnetwork_interface_info): Handle case when ifr_flags is negative.

7005 * xdisp.c (iterate_out_of_display_property): xassert that
7006 IT->position is set to within IT->object's boundaries. Break from
7007 the loop as soon as EOB is reached; avoids infloops in redisplay
7008 when IT->position is set up wrongly due to some bug.
7009 Set IT->current to match the bidi iterator unconditionally.
7010 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7011 entry. Force push_it to save on the stack the current
7012 buffer/string position, to be restored by pop_it. Fix flags in
7013 the iterator structure wrt the object coming from a display
7014 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7015 properties. (Bug#9284)
7017 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7019 * fontset.c (fontset_get_font_group): Add proper type checks.

7057 display property strides EOL and includes a newline, as in
7058 longlines-mode. (Bug#9254)
7059 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7060 word-wrap under bidirectional display. (Bug#9224)
7062 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7063 is non-zero, even if the data buffer is NULL. Fixes a crash in
7064 vertical-motion with longlines-mode. (Bug#9254)
7066 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7068 * bidi.c <bidi_cache_total_alloc>: Now static.
7069 (bidi_initialize): Initialize bidi_cache_total_alloc.
7071 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7072 cache. (Bug#9221)
7074 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7075 amount allocated this far in `bidi_cache_total_alloc'.
7076 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7077 non-zero, only free the data buffer without restoring the cache
7078 contents. All callers changed.
7080 * dispextern.h (bidi_unshelve_cache): Update prototype.
7082 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7083 (move_it_in_display_line, move_it_to)
7084 (move_it_vertically_backward, move_it_by_lines): Replace the call
7085 to xfree to an equivalent call to bidi_unshelve_cache.
7086 (move_it_in_display_line_to): Fix logic of returning
7087 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7089 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7091 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7092 came from a string character with a `cursor' property. (Bug#9229)

7154 last character M-[char] is translated to ESC [char] (bug#7541).
7156 2011-08-02 Kenichi Handa <handa@m17n.org>
7158 * lisp.h (uniprop_table): Extern it.
7160 * chartab.c (uniprop_table): Make it non-static.
7162 2011-08-01 Eli Zaretskii <eliz@gnu.org>
7164 * xdisp.c (forward_to_next_line_start): Accept additional argument
7165 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7166 on the newline.
7167 (reseat_at_next_visible_line_start): Use the bidi iterator state
7168 returned by forward_to_next_line_start to restore the state of
7169 it->bidi_it after backing up to previous newline. (Bug#9212)
7171 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
7173 * regex.c (re_comp): Protoize.
7174 (re_exec): Fix return type.
7175 (regexec): Fix type of `ret'. (Bug#9203)
7177 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7179 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7180 This is needed if max-image-size is a floating-point number.
7182 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7184 * print.c (print_object): Print empty symbol as ##.
7186 * lread.c (read1): Read ## as empty symbol.
7188 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7190 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7191 setting frame foreground color (Bug#9175).
7192 (x_set_background_color): Likewise.
7194 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7195 contents (Bug#9176).
7196 (EmacsTooltip -init): Remove bezels and add shadows to
7197 tooltip windows.
7199 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7200 or scroll bar (Bug#8470).
7202 * nsfont.m (nsfont_open): Remove assignment to voffset and
7203 unnecessary vars hshink, expand, hd, full_height, min_height.
7204 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7206 * nsterm.h (nsfont_info): Remove voffset field.
7208 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7210 Implement strike-through and overline on NextStep (Bug#8863).
7212 * nsfont.m (nsfont_open): Use underline position provided by font,
7213 instead of hard-coded value of 2.
7214 (nsfont_draw): Call ns_draw_text_decoration instead.
7216 * nsterm.h: Add declaration for ns_draw_text_decoration.
7218 * nsterm.m (ns_draw_text_decoration): New function for drawing
7219 underline, overline, and strike-through.
7220 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
7221 ns_draw_text_decoration. Change treatment of cursor drawing to
7222 accommodate underlining, etc.
7224 2011-07-28 Eli Zaretskii <eliz@gnu.org>
7226 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
7227 default.
7229 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7231 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7232 Without this fix, if a signal arrives just after memory fills up,
7233 'malloc' might be invoked reentrantly.
7235 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7236 In other words, assume that every image size is allowed, on non-X
7237 hosts. This assumption is probably wrong, but it lets Emacs compile.
7239 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7241 * regex.c (re_iswctype): Convert return values to boolean.
7243 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7245 * xdisp.c (compute_display_string_pos): Don't use cached display
7246 string position if the buffer had its restriction changed.
7247 (Bug#9184)
7249 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7251 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7253 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7255 Integer signedness and overflow and related fixes. (Bug#9079)
7257 * bidi.c: Integer size and overflow fixes.
7258 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7259 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7260 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7261 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7262 (bidi_find_other_level_edge):
7263 Use ptrdiff_t instead of EMACS_INT where either will do.
7264 This works better on 32-bit hosts configured --with-wide-int.
7265 (bidi_cache_ensure_space): Check for size-calculation overflow.
7266 Use % rather than repeated addition, for better worst-case speed.
7267 Don't set bidi_cache_size until after xrealloc returns, because it
7268 might not return.
7269 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7270 (bidi_cache_ensure_space): Also check that the bidi cache size
7271 does not exceed that of the largest Lisp string or buffer. See Eli
7272 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7274 * alloc.c (__malloc_size_t): Remove.
7275 All uses replaced by size_t. See Andreas Schwab's note
7276 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7278 * image.c: Improve checking for integer overflow.
7279 (check_image_size): Assume that f is nonnull, since
7280 it is always nonnull in practice. This is one less thing to
7281 worry about when checking for integer overflow later.
7282 (x_check_image_size): New function, which checks for integer
7283 overflow issues inside X.
7284 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7285 This removes the need for a memory_full check.
7286 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7287 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7288 (xbm_read_bitmap_data): Change locals back to 'int', since
7289 their values must fit in 'int'.
7290 (xpm_load_image, png_load, tiff_load):
7291 Invoke x_create_x_image_and_pixmap earlier,
7292 to avoid much needless work if the image is too large.
7293 (tiff_load): Treat overly large images as if
7294 x_create_x_image_and_pixmap failed, not as malloc failures.
7295 (gs_load): Use x_check_image_size.
7297 * gtkutil.c: Omit integer casts.
7298 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7299 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7301 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7303 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7304 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7305 would wrongly return t on a 64-bit host.
7307 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7308 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7309 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7310 and therefore cause GCC to emit a bogus diagnostic in some cases.
7312 * image.c: Integer signedness and overflow and related fixes.
7313 This is not an exhaustive set of fixes, but it's time to
7314 record what I've got.
7315 (lookup_pixel_color, check_image_size): Remove redundant decls.
7316 (check_image_size): Don't assume that arbitrary EMACS_INT values
7317 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7318 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7319 (tiff_load, imagemagick_load_image):
7320 Check for overflow in size calculations.
7321 (x_create_x_image_and_pixmap): Remove unnecessary test for
7322 xmalloc returning NULL; that can't happen.
7323 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7324 (xpm_color_bucket): Use better integer hashing function.
7325 (xpm_cache_color): Don't possibly over-allocate memory.
7326 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7327 (gif_memory_source):
7328 Use ptrdiff_t, not int or size_t, to record sizes.
7329 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7330 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7331 either works, as we prefer signed integers.
7332 (tiff_read_from_memory, tiff_write_from_memory):
7333 Return tsize_t, not size_t, since that's what the TIFF API wants.
7334 (tiff_read_from_memory): Don't fail simply because the read would
7335 go past EOF; instead, return a short read.
7336 (tiff_load): Omit no-longer-needed casts.
7337 (Fimagemagick_types): Don't assume size fits into 'int'.
7339 Improve hashing quality when configured --with-wide-int.
7340 * fns.c (hash_string): New function, taken from sxhash_string.
7341 Do not discard information about ASCII character case; this
7342 discarding is no longer needed.
7343 (sxhash-string): Use it. Change sig to match it. Caller changed.
7344 * lisp.h: Declare it.
7345 * lread.c (hash_string): Remove, since we now use fns.c's version.
7346 The fns.c version returns a wider integer if --with-wide-int is
7347 specified, so this should help the quality of the hashing a bit.
7349 * emacs.c: Integer overflow minor fix.
7350 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7351 Define only if GNU_LINUX.
7352 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7354 * dispnew.c: Integer signedness and overflow fixes.
7355 Remove unnecessary forward decls, that were a maintenance hassle.
7356 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7357 All uses changed.
7358 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7359 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7360 (prepare_desired_row, line_draw_cost):
7361 Use int, not unsigned, where either works.
7362 (save_current_matrix, restore_current_matrix):
7363 Use ptrdiff_t, not size_t, where either works.
7364 (init_display): Check for overflow more accurately, and without
7365 relying on undefined behavior.
7367 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7368 Remove, replacing with the new symbols in lisp.h. All uses changed.
7369 * fileio.c (make_temp_name):
7370 * filelock.c (lock_file_1, lock_file):
7371 * xdisp.c (message_dolog):
7372 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7373 Use pMd etc. instead.
7374 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7375 replacing the pWIDE etc. symbols removed from editfns.c.
7377 * keyboard.h (num_input_events): Now uintmax_t.
7378 This is (very slightly) less likely to mess up due to wraparound.
7379 All uses changed.
7381 * buffer.c: Integer signedness fixes.
7382 (alloc_buffer_text, enlarge_buffer_text):
7383 Use ptrdiff_t rather than size_t when either will do, as we prefer
7384 signed integers.
7386 * alloc.c: Integer signedness and overflow fixes.
7387 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7388 (__malloc_size_t): Default to size_t, not to int.
7389 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7390 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7391 Prefer ptrdiff_t to size_t when either would do, as we prefer
7392 signed integers.
7393 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7394 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7395 Now const. Initialize with values that are in range even if char
7396 is signed.
7397 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7398 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7399 These functions do the right thing with sizes > 2**32.
7400 (check_depth): Now ptrdiff_t, not int.
7401 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7402 Adjust to new way of storing sizes. Check for size overflow bugs
7403 in rest of code.
7404 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7405 slightly wrong anyway, as it missed one instance of
7406 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7407 (refill_memory_reserve): Omit needless cast to size_t.
7408 (mark_object_loop_halt): Mark as externally visible.
7410 * xselect.c: Integer signedness and overflow fixes.
7411 (Fx_register_dnd_atom, x_handle_dnd_message):
7412 Use ptrdiff_t, not size_t, since we prefer signed.
7413 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7414 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7415 x_dnd_atoms_size and x_dnd_atoms_length.
7417 * doprnt.c: Prefer signed to unsigned when either works.
7418 * eval.c (verror):
7419 * doprnt.c (doprnt):
7420 * lisp.h (doprnt):
7421 * xdisp.c (vmessage):
7422 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7423 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7424 prefer signed arithmetic to avoid comparison confusion.
7425 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7426 but is a bit tricky.
7428 Assume freestanding C89 headers, string.h, stdlib.h.
7429 * data.c, doprnt.c, floatfns.c, print.c:
7430 Include float.h unconditionally.
7431 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7432 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7433 * regex.c: Likewise for stddef.h, string.h.
7434 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7435 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7436 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7437 (STDC_HEADERS): Remove obsolete defines.
7438 * sysdep.c: Include limits.h unconditionally.
7440 Assume support for memcmp, memcpy, memmove, memset.
7441 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7442 * regex.c (memcmp, memcpy):
7443 Remove; we assume C89 now.
7445 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7446 (__malloc_safe_bcopy): Remove; no longer needed.
7448 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7449 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7450 well either way, and we prefer signed to unsigned.
7452 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7454 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7455 closes the connection while we're reading (bug#9182).
7457 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7459 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7460 are specified (Bug#9168).
7462 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7464 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7465 Found by GCC static checking and --with-wide-int on a 32-bit host.
7467 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7469 * xdisp.c (compute_display_string_pos): Fix logic of caching
7470 previous display string position. Initialize cached_prev_pos to
7471 -1. Fixes slow-down at the beginning of a buffer.
7473 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7475 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7476 for attrs[LFACE_FONTSET_INDEX].
7478 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7480 * xml.c (parse_region): Remove unused local
7481 that was recently introduced.
7483 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7485 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7486 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7488 * xdisp.c (move_it_in_display_line_to): Record the best matching
7489 position for TO_CHARPOS while scanning the line, and restore it on
7490 exit if none of the characters scanned was an exact match.
7491 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7492 when exact match is impossible due to invisible text, and the
7493 lines are truncated.
7495 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7497 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7498 for OSX >= 10.7.
7500 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7502 Fix a significant slow-down of cursor motion with C-n, C-p,
7503 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7504 auto-repeat under bidi redisplay in fontified buffers.
7505 * xdisp.c (compute_stop_pos_backwards): New function.
7506 (next_element_from_buffer): Call compute_stop_pos_backwards to
7507 find a suitable prev_stop when we find ourselves before
7508 base_level_stop.
7509 (reseat): Don't look for prev_stop, as that could mean a very long
7510 run.
7511 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7512 <cached_disp_overlay_modiff>: Cache for last found display string
7513 position.
7514 (compute_display_string_pos): Return the cached position if asked
7515 about the same buffer in the same area of character positions, and
7516 the buffer wasn't changed since the time the display string
7517 position was cached.
7519 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7521 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7522 is an integer, which is important for empty lines. (Bug#9149)
7524 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7526 * frame.c (Fmodify_frame_parameters): In tty case, update the
7527 default face if necessary (Bug#4238).
7529 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7531 * editfns.c (Fstring_to_char): No need to explain what a character
7532 is in the docstring (Bug#6576).
7534 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7536 * xml.c (parse_region): Make sure we always return a tree.
7538 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7540 * xml.c (parse_region): If a document contains only comments,
7541 return that, too.
7543 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7545 * xml.c (make_dom): Return comments, too.
7547 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7549 Port to OpenBSD.
7550 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7551 and the surrounding thread.
7552 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7553 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7554 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7555 timer goes off.
7556 * s/openbsd.h (BROKEN_SIGIO): Define.
7557 * unexelf.c (unexec) [__OpenBSD__]:
7558 Don't update the .mdebug section of the Alpha COFF symbol table.
7560 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7562 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7563 (bug#8460).
7565 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7567 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7568 This fixes some race conditions on the permissions of any newly
7569 created file.
7571 * alloc.c (valid_pointer_p): Use pipe, not open.
7572 This fixes some permissions issues when debugging.
7574 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7575 If fchown fails to set both uid and gid, try to set just gid,
7576 as that is sometimes allowed. Adjust the file's mode to eliminate
7577 setuid or setgid bits that are inappropriate if fchown fails.
7579 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7581 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7582 to compare Lisp_Objects.
7583 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7584 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7585 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7587 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7589 * lread.c (read_integer): Unread even EOF character.
7590 (read1): Likewise. Properly record start position of symbol.
7592 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7593 symbol character follows.
7595 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7597 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7598 This works around a problem with the previous change to Fcopy_file.
7599 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7600 and without this change, GCC might complain about discarding
7601 fchown's return value.
7603 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7605 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7607 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7609 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7611 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7613 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7614 it's used from the C level.
7616 * process.c: Use the same condition for POLL_FOR_INPUT in both
7617 keyboard.c and process.c (bug#1858).
7619 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7621 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7622 (Fgnutls_boot): Use it.
7624 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7626 * doc.c (Fsubstitute_command_keys): Revert last change.
7628 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7630 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7631 quotes the next character, and doesn't affect other longer
7632 sequences (bug#8935).
7634 * lread.c (syms_of_lread): Clarify that is isn't only
7635 `eval-buffer' and `eval-defun' that's affected by

7646 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7647 (elsz): Now a signed constant, not a size_t var. We prefer signed
7648 types to unsigned, to avoid integer comparison confusion. Without
7649 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7650 "cannot optimize loop, the loop counter may overflow", a symptom
7651 of the confusion.

7681 (display_string): If we need to ignore text properties of
7682 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7683 original value of -1 will not work with bidi.)
7684 (compute_display_string_pos): First arg is now struct
7685 `text_pos *'; all callers changed. Support display properties on
7686 Lisp strings.

7688 strings.
7689 (init_iterator, reseat_1, reseat_to_string): Initialize the

7693 Fix calculation of the object to scan. Fixes an error when using
7694 arrow keys.
7695 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7696 base_level_stop; instead, set base_level_stop to BEGV.
7697 Fixes crashes in vertical-motion.
7698 (next_element_from_buffer): Improve commentary for when
7699 the iterator is before prev_stop.
7700 (init_iterator): Initialize bidi_p from the default value of

7721 character that is not the first one in the visual order.
7722 (get_visually_first_element): New function, refactored from common
7723 parts of next_element_from_buffer, next_element_from_string, and
7724 next_element_from_c_string.
7725 (tool_bar_lines_needed, redisplay_tool_bar)
7726 (display_menu_bar): Force left-to-right direction. Add a FIXME
7727 comment for making that be controlled by a user option.

7741 pushed the iterator stack, restore the internal state of the bidi
7742 iterator by calling bidi_pop_it same number of times.
7743 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
7744 and we are bidi-iterating, don't decrement the iterator position;
7745 instead, set the first_elt flag in the bidi iterator, to produce
7746 the same effect.
7747 (reseat_1): Remove redundant setting of string_from_display_prop_p.
7748 (push_display_prop): xassert that we are iterating a buffer.
7749 (push_it, pop_it): Save and restore paragraph_embedding member.
7750 (handle_single_display_spec, next_overlay_string)
7751 (get_overlay_strings_1, reseat_1, reseat_to_string)

7761 popping after iteration over a string that came from a display
7762 property. Fix a typo in popping stretch info. Add an assertion
7763 for verifying that the iterator position is in sync with the bidi
7764 iterator.

7766 (push_display_prop): Fix initialization of paragraph direction for
7767 string when that of the parent object is not yet determined.

7769 iterator with IT's position. (Bug#7616)
7770 (find_row_edges): If ROW->start.pos gives position
7771 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

7773 Reset the from_disp_prop_p flag.
7774 (SAVE_IT, RESTORE_IT): New macros.

7783 (move_it_in_display_line_to): If iterator ended up at
7784 EOL, but we never saw any buffer positions smaller than
7785 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
7786 motion in bidi-reordered lines.
7787 (move_it_in_display_line_to): Record prev_method and prev_pos
7788 immediately before the call to set_iterator_to_next. Fixes cursor
7789 motion in bidi-reordered lines with stretch glyphs and strings
7790 displayed in margins. (Bug#8133) (Bug#8867)
7791 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
7792 TO_CHARPOS.
7793 (pos_visible_p): Support positions in bidi-reordered lines.
7794 Save and restore bidi cache.
7796 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

8218 Random fixes. E.g., (random) never returned negative values.
8219 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8220 subseconds part to the entropy, as that's a bit more random.
8221 Prefer signed to unsigned, since the signedness doesn't matter and
8222 in general we prefer signed. When given a limit, use a
8223 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8224 latter isn't right if USE_2_TAGS_FOR_INTS.
8225 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8226 not 0..VALMASK. Don't discard "excess" bits that random () returns.
8228 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8230 * textprop.c (text_property_stickiness):

8239 This is more efficient than Ffile_directory_p and avoids a minor race.
8241 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8243 * buffer.c (Foverlay_put): Say what the return value is
8244 (bug#7835).

8247 is a directory before asking whether to use the file name
8248 (bug#7564).
8249 (barf_or_query_if_file_exists): Make the "File is a directory"
8250 error be more correct.
8252 * fns.c (Frequire): Remove the mention of the .gz files, since
8253 that's installation-specific, but keep the mention of
8254 `get-load-suffixes'.
8256 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8258 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

8269 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
8270 Also (re)move comments that are misplaced or no longer relevant.
8272 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8274 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

8333 (syms_of_keymap): Defsubr make-composed-keymap.
8334 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

8369 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
8371 * eval.c (struct backtrace): Simplify and port the data structure.
8372 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8373 signed bit field, as this assumption is not portable and it makes
8374 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8375 "char debug_on_exit : 1" as this is not portable either; instead,
8376 use the portable "unsigned int debug_on_exit : 1". Remove unused
8377 member evalargs. Remove obsolete comments about cc bombing out.
8379 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

8541 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
8543 Integer and buffer overflow fixes (Bug#8873).
8545 * print.c (printchar, strout): Check for string overflow.
8546 (PRINTPREPARE, printchar, strout):
8547 Don't set size unless allocation succeeds.
8549 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
8550 for sizes. Check for string overflow more accurately.
8551 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
8553 * macros.c: Integer and buffer overflow fixes.
8554 * keyboard.h (struct keyboard.kbd_macro_bufsize):
8555 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
8556 Use ptrdiff_t, not int, for sizes.
8557 Don't increment bufsize until after realloc succeeds.
8558 Check for size-calculation overflow.
8559 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
8561 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
8563 * lread.c: Integer overflow fixes.
8564 (read_integer): Radix is now EMACS_INT, not int,
8565 to improve quality of diagnostics for out-of-range radices.
8566 Calculate buffer size correctly for out-of-range radices.
8567 (read1): Check for integer overflow in radices, and in
8568 read-circle numbers.
8569 (read_escape): Avoid int overflow.
8570 (Fload, openp, read_buffer_size, read1)
8571 (substitute_object_recurse, read_vector, read_list, map_obarray):
8572 Use ptrdiff_t, not int, for sizes.
8573 (read1): Use EMACS_INT, not int, for sizes.
8574 Check for size overflow.
8576 * image.c (cache_image): Check for size arithmetic overflow.
8578 * lread.c: Integer overflow issues.
8579 (saved_doc_string_size, saved_doc_string_length)
8580 (prev_saved_doc_string_size, prev_saved_doc_string_length):
8581 Now ptrdiff_t, not int.
8582 (read1): Don't assume doc string length fits in int. Check for
8583 out-of-range doc string lengths.
8584 (read_list): Don't assume file position fits in int.
8585 (read_escape): Check for hex character overflow.
8587 2011-06-22 Leo Liu <sdl.web@gmail.com>
8589 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
8590 Move to minibuffer.el.
8592 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8594 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
8595 The following patches are for when GLYPH_DEBUG && !XASSERT.
8596 * dispextern.h (trace_redisplay_p, dump_glyph_string):
8597 * dispnew.c (flush_stdout):
8598 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
8599 Mark as externally visible.
8600 * dispnew.c (check_window_matrix_pointers): Now static.
8601 * dispnew.c (window_to_frame_vpos):
8602 * xfns.c (unwind_create_frame):
8603 * xterm.c (x_check_font): Remove unused local.
8604 * scroll.c (CHECK_BOUNDS):
8605 * xfaces.c (cache_fache): Rename local to avoid shadowing.
8606 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8607 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8608 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8609 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8610 Now static.
8611 (debug_method_add): Use va_list and vsprintf rather than relying
8612 on undefined behavior with wrong number of arguments.
8613 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8614 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8615 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8616 since we're not interested in debugging glyphs with old libraries.
8617 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8618 GCC 4.6.0's static checking.
8620 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8622 Integer overflow and signedness fixes (Bug#8873).
8623 A few related buffer overrun fixes, too.

8634 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
8635 (.bitmaps_last):
8636 * xfaces.c (load_pixmap):
8637 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
8638 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
8639 (.bitmaps_last, struct x_output.icon_bitmap):
8640 Use ptrdiff_t, not int, for bitmap indexes.
8641 (x_allocate_bitmap_record): Check for size overflow.
8642 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
8644 Use ptrdiff_t, not int, for overlay counts.
8645 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
8646 * editfns.c (overlays_around, get_pos_property):
8647 * textprop.c (get_char_property_and_overlay):
8648 * xdisp.c (next_overlay_change, note_mouse_highlight):
8649 * xfaces.c (face_at_buffer_position):
8650 * buffer.c (OVERLAY_COUNT_MAX): New macro.
8651 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
8652 (Fnext_overlay_change, Fprevious_overlay_change)
8653 (mouse_face_overlay_overlaps, Foverlays_in):
8654 Use ptrdiff_t, not int, for sizes.
8655 (overlays_at, overlays_in): Check for size-calculation overflow.
8657 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8659 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8660 (x_session_initialize): Do not assume string length fits in int.
8662 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8663 This is unlikely, but can occur if DPI is outlandish.
8665 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8666 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8668 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
8669 * xrdb.c (magic_file_p, search_magic_path):
8670 Omit last arg SUFFIX; it was always 0. All callers changed.
8671 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
8673 * xfont.c (xfont_match): Avoid need for strlen.
8675 * xfns.c: Don't assume strlen fits in int.
8676 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
8678 * xdisp.c (message_log_check_duplicate): Return intmax_t,
8679 not unsigned long, as we prefer signed integers. All callers changed.
8680 Detect integer overflow in repeat count.
8681 (message_dolog): Don't assume print length fits in 39 bytes.
8682 (display_mode_element): Don't assume strlen fits in int.
8684 * termcap.c: Don't assume sizes fit in int and never overflow.
8685 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
8686 (gobble_line): Check for size-calculation overflow.
8688 * minibuf.c (Fread_buffer):
8689 * lread.c (intern, intern_c_string):
8690 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
8691 Don't assume string length fits in int.
8693 * keyboard.c (parse_tool_bar_item):
8694 * gtkutil.c (style_changed_cb): Avoid need for strlen.
8696 * font.c: Don't assume string length fits in int.
8697 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
8698 Use ptrdiff_t, not int.
8699 (font_intern_prop): Don't assume string length fits in int.
8700 Don't assume integer property fits in fixnum.
8701 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
8703 * filelock.c: Fix some buffer overrun and integer overflow issues.
8704 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
8705 Reformulate so as not to need the command string.
8706 Invoke gzip -cd rather than gunzip, as it's more portable.
8707 (lock_info_type, lock_file_1, lock_file):
8708 Don't assume pid_t and time_t fit in unsigned long.
8709 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8710 (current_lock_owner): Prefer signed type for sizes.
8711 Use memcpy, not strncpy, where memcpy is what is really wanted.
8712 Don't assume (via atoi) that time_t and pid_t fit in int.
8713 Check for time_t and/or pid_t out of range, e.g., via a network share.
8714 Don't alloca where an auto var works fine.
8716 * fileio.c: Fix some integer overflow issues.
8717 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8718 Don't assume string length fits in int.
8719 (directory_file_name): Don't assume string length fits in long.
8720 (make_temp_name): Don't assume pid fits in int, or that its print
8721 length is less than 20.
8723 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8725 * coding.c (make_subsidiaries): Don't assume string length fits in int.
8727 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
8729 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
8730 We prefer signed integers, even for size calculations.
8732 * emacs.c: Don't assume string length fits in 'int'.
8733 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
8734 (main): Don't invoke strlen when not needed.
8736 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
8737 (XD_DEBUG_MESSAGE): Don't waste a byte.
8739 * callproc.c (getenv_internal_1, getenv_internal)
8740 (Fgetenv_internal):
8741 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8743 * lread.c (invalid_syntax): Omit length argument.
8744 All uses changed. This doesn't fix a bug, but it simplifies the
8745 code away from its former Hollerith-constant appearance, and it's
8746 one less 'int' to worry about when looking at integer-overflow issues.
8747 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8749 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8750 This didn't break anything, but it didn't help either.
8751 It's confusing to put a bogus integer in a place where the actual
8752 value does not matter.
8753 (LIST_END_P): Remove unused macro and its bogus comment.
8754 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8756 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8757 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8758 implementation.
8759 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8760 We prefer signed types, and the value cannot exceed the EMACS_INT
8761 range anyway (because otherwise the length would not be representable).
8762 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8763 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8764 This avoids a GCC warning when WIDE_EMACS_INT.
8766 * indent.c (sane_tab_width): New function.
8767 (current_column, scan_for_column, Findent_to, position_indentation)
8768 (compute_motion): Use it. This is just for clarity.
8769 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8771 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8773 * lisp.h (lint_assume): New macro.
8774 * composite.c (composition_gstring_put_cache):
8775 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8777 * editfns.c, insdel.c:
8778 Omit unnecessary forward decls, to simplify future changes.
8780 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8782 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8784 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8785 Use much-faster test for byte-length change.
8786 Don't assume string byte-length fits in 'int'.
8787 Check that character arg fits in 'int'.
8788 (mapcar1): Declare byte as byte, for clarity.
8790 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
8792 * fns.c (concat): Catch string overflow earlier.
8793 Do not rely on integer wraparound.
8795 * dispextern.h (struct it.overlay_strings_charpos)
8796 (struct it.selective): Now EMACS_INT, not int.
8797 * xdisp.c (forward_to_next_line_start)
8798 (back_to_previous_visible_line_start)
8799 (reseat_at_next_visible_line_start, next_element_from_buffer):
8800 Don't arbitrarily truncate the value of 'selective' to int.
8802 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
8804 * composite.c: Don't truncate sizes to 'int'.
8805 (composition_gstring_p, composition_reseat_it)
8806 (composition_adjust_point): Use EMACS_INT, not int.
8807 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
8808 not EMACS_UINT, for indexes.
8810 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
8812 * buffer.c: Include <verify.h>.
8813 (struct sortvec.priority, struct sortstr.priority):
8814 Now EMACS_INT, not int.
8815 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
8816 (struct sortstr.size, record_overlay_string)
8817 (struct sortstrlist.size, struct sortlist.used):
8818 Don't truncate size to int.
8819 (record_overlay_string): Check for size-calculation overflow.
8820 (init_buffer_once): Check at compile-time, not run-time.
8822 2011-06-22 Jim Meyering <meyering@redhat.com>
8824 Don't leak an XBM-image-sized buffer
8825 * image.c (xbm_load): Free the image buffer after using it.
8827 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
8829 Port to Sun C.
8830 * composite.c (find_automatic_composition): Omit needless 'return 0;'
8831 that Sun C diagnosed.
8832 * fns.c (secure_hash): Fix pointer signedness issue.
8833 * intervals.c (static_offset_intervals): New function.
8834 (offset_intervals): Use it.
8836 2011-06-21 Leo Liu <sdl.web@gmail.com>
8838 * deps.mk (fns.o):
8839 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
8840 sha512.h.
8842 * fns.c (secure_hash): Rename from crypto_hash_function and change
8843 the first arg to accept symbols.
8844 (Fsecure_hash): New primitive.
8845 (syms_of_fns): New symbols.
8847 2011-06-20 Deniz Dogan <deniz@dogan.se>
8849 * process.c (Fset_process_buffer): Clarify return value in
8850 docstring.
8852 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
8854 * dispnew.c (add_window_display_history): Use BVAR.
8856 * xdisp.c (debug_method_add): Use BVAR.
8857 (check_window_end, dump_glyph_matrix, dump_glyph)
8858 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
8860 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
8861 Likewise.
8863 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
8864 check till after the cache is created in init_frame_faces.
8866 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
8868 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
8870 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
8872 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
8873 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
8874 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
8876 Improve buffer-overflow checking (Bug#8873).
8877 * fileio.c (Finsert_file_contents):
8878 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
8879 Remove the old (too-loose) buffer overflow checks.
8880 They weren't needed, since make_gap checks for buffer overflow.
8881 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
8882 The old code merely checked for Emacs fixnum overflow, and relied
8883 on undefined (wraparound) behavior. The new code avoids undefined
8884 behavior, and also checks for ptrdiff_t and/or size_t overflow.
8886 * editfns.c (Finsert_char): Don't dump core with very negative counts.
8887 Tune. Don't use wider integers than needed. Don't use alloca.
8888 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
8890 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
8892 * insdel.c, lisp.h (buffer_overflow): New function.
8893 (insert_from_buffer_1, replace_range, replace_range_2):
8894 * insdel.c (make_gap_larger):
8895 * editfns.c (Finsert_char):
8896 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
8898 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
8900 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
8902 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
8904 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
8905 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
8907 * fileio.c: Don't assume EMACS_INT fits in off_t.
8908 (emacs_lseek): New static function.
8909 (Finsert_file_contents, Fwrite_region): Use it.
8910 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
8912 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
8914 * fns.c: Don't overflow int when computing a list length.
8915 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
8916 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
8917 truncation on 64-bit hosts. Check for QUIT every
8918 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
8919 faster and is responsive enough.
8920 (Flength): Report an error instead of overflowing an integer.
8921 (Fsafe_length): Return a float if the value is not representable
8922 as a fixnum. This shouldn't happen except in contrived situations.
8923 (Fnthcdr, Fsort): Don't assume list length fits in int.
8924 (Fcopy_sequence): Don't assume vector length fits in int.
8926 * alloc.c: Check that resized vectors' lengths fit in fixnums.
8927 (header_size, word_size): New constants.
8928 (allocate_vectorlike): Don't check size overflow here.
8929 (allocate_vector): Check it here instead, since this is the only
8930 caller of allocate_vectorlike that could cause overflow.
8931 Check that the new vector's length is representable as a fixnum.
8933 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
8934 The previous code was bogus. For example, next_almost_prime (32)
8935 returned 39, which is undesirable as it is a multiple of 3; and
8936 next_almost_prime (24) returned 25, which is a multiple of 5 so
8937 why was the code bothering to check for multiples of 7?
8939 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
8941 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
8943 Variadic C functions now count arguments with ptrdiff_t.
8944 This partly undoes my 2011-03-30 change, which replaced int with size_t.
8945 Back then I didn't know that the Emacs coding style prefers signed int.
8946 Also, in the meantime I found a few more instances where arguments
8947 were being counted with int, which may truncate counts on 64-bit
8948 machines, or EMACS_INT, which may be unnecessarily wide.
8949 * lisp.h (struct Lisp_Subr.function.aMANY)
8950 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
8951 Arg counts are now ptrdiff_t, not size_t.
8952 All variadic functions and their callers changed accordingly.
8953 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
8954 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
8955 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
8956 * callint.c (Fcall_interactively): Check arg count for overflow,
8957 to avoid potential buffer overrun. Use signed char, not 'int',
8958 for 'varies' array, so that we needn't bother to check its size
8959 calculation for overflow.
8960 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
8961 * eval.c (apply_lambda):
8962 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
8963 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
8964 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
8966 * callint.c (Fcall_interactively): Don't use index var as event count.
8968 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
8969 * mem-limits.h (SIZE): Remove; no longer used.
8971 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
8973 Remove unnecessary casts.
8974 * xterm.c (x_term_init):
8975 * xfns.c (x_set_border_pixel):
8976 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
8977 These aren't needed now that we assume ANSI C.
8979 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
8980 It's more likely to cause problems (due to unsigned overflow)
8981 than to cure them.
8983 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
8985 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
8987 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
8989 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
8991 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
8993 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
8995 GLYPH_CODE_FACE returns EMACS_INT, not int.
8996 * dispextern.h (merge_faces):
8997 * xfaces.c (merge_faces):
8998 * xdisp.c (get_next_display_element, next_element_from_display_vector):
8999 Don't assume EMACS_INT fits in int.
9001 * character.h (CHAR_VALID_P): Remove unused parameter.
9002 * fontset.c, lisp.h, xdisp.c: All uses changed.
9004 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9006 * fns.c (concat): Minor tuning based on overflow analysis.
9007 This doesn't fix any bugs. Use int to hold character, instead
9008 of constantly refetching from Emacs object. Use XFASTINT, not
9009 XINT, for value known to be a character. Don't bother comparing
9010 a single byte to 0400, as it's always less.
9012 * floatfns.c (Fexpt):
9013 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9015 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9016 for characters.
9018 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9020 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9021 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9022 incorrectly succeed when S was a string, because 4294967386 was
9023 truncated before it was used.
9025 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9026 Otherwise, an out-of-range integer could cause undefined behavior
9027 on a 64-bit host.
9029 * composite.c: Use int, not EMACS_INT, for characters.
9030 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9031 EMACS_INT, for values that are known to be in character range.
9032 This doesn't fix any bugs but is the usual style inside Emacs and
9033 may generate better code on 32-bit machines.
9035 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9036 This is for reasons similar to the recent CHAR_STRING fix.
9037 * charset.c (Fencode_char): Check that character arg is actually
9038 a character. Pass an int to ENCODE_CHAR.
9039 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9040 wider than 'int', as a compile-time check to prevent future regressions
9041 in this area.
9043 * character.c (char_string): Remove unnecessary casts.
9045 Make sure a 64-bit char is never passed to CHAR_STRING.
9046 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9047 by silently ignoring the top 32 bits, allowing some values
9048 that were far too large to be valid characters.
9049 * character.h: Include <verify.h>.
9050 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9051 arguments are no wider than unsigned, as a compile-time check
9052 to prevent future regressions in this area.
9053 * data.c (Faset):
9054 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9055 (Fsubst_char_in_region):
9056 * fns.c (concat):
9057 * xdisp.c (decode_mode_spec_coding):
9058 Adjust to CHAR_STRING's new requirement.
9059 * editfns.c (Finsert_char, Fsubst_char_in_region):
9060 * fns.c (concat): Check that character args are actually
9061 characters. Without this test, these functions did the wrong
9062 thing with wildly out-of-range values on 64-bit hosts.
9064 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9065 These casts should not be needed on 32-bit hosts, either.
9066 * keyboard.c (read_char):
9067 * lread.c (Fload): Remove casts to unsigned.
9069 * lisp.h (UNSIGNED_CMP): New macro.
9070 This fixes comparison bugs on 64-bit hosts.
9071 (ASCII_CHAR_P): Use it.
9072 * casefiddle.c (casify_object):
9073 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9074 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9075 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9076 * dispextern.h (FACE_FROM_ID):
9077 * keyboard.c (read_char): Use UNSIGNED_CMP.
9079 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9080 not to EMACS_INT, to avoid GCC warning.
9082 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9084 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9085 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9086 isn't needed on 32-bit machines.
9088 * buffer.c (Fgenerate_new_buffer_name):
9089 Use EMACS_INT for count, not int.
9090 (advance_to_char_boundary): Return EMACS_INT, not int.
9092 * data.c (Qcompiled_function): Now static.
9094 * window.c (window_body_lines): Now static.
9096 * image.c (gif_load): Rename local to avoid shadowing.
9098 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9099 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9100 * alloc.c (make_save_value): Integer argument is now of type
9101 ptrdiff_t, not int.
9102 (mark_object): Use ptrdiff_t, not int.
9103 * lisp.h (pD): New macro.
9104 * print.c (print_object): Use it.
9106 * alloc.c: Use EMACS_INT, not int, to count objects.
9107 (total_conses, total_markers, total_symbols, total_vector_size)
9108 (total_free_conses, total_free_markers, total_free_symbols)
9109 (total_free_floats, total_floats, total_free_intervals)
9110 (total_intervals, total_strings, total_free_strings):
9111 Now EMACS_INT, not int. All uses changed.
9112 (Fgarbage_collect): Compute overall total using a double, so that
9113 integer overflow is less likely to be a problem. Check for overflow
9114 when converting back to an integer.
9115 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9116 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9117 These were 'int' variables that could overflow on 64-bit hosts;
9118 they were never used, so remove them instead of repairing them.
9119 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9120 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9121 Previously, this ceilinged at INT_MAX, but that doesn't work on
9122 64-bit machines.
9123 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9125 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9126 (allocate_vectorlike): Check for ptrdiff_t overflow.
9127 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9128 when a (possibly-narrower) signed value would do just as well.
9129 We prefer using signed arithmetic, to avoid comparison confusion.
9131 * alloc.c: Catch some string size overflows that we were missing.
9132 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9133 for convenience in STRING_BYTES_MAX.
9134 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9135 The definition here is exact; the one in lisp.h was approximate.
9136 (allocate_string_data): Check for string overflow. This catches
9137 some instances we weren't catching before. Also, it catches
9138 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9139 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9140 and ptrdiff_t and EMACS_INT are both 64 bits.
9142 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9143 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9144 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9146 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9148 * alloc.c (Fmake_string): Check for out-of-range init.
9150 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9152 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9154 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
9156 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
9157 xg_get_default_scrollbar_width.
9159 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
9160 (int_gtk_range_get_value): Move to the scroll bar part of the file.
9161 (style_changed_cb): Call update_theme_scrollbar_width and call
9162 x_set_scroll_bar_default_width and xg_frame_set_char_size for
9163 all frames (Bug#8505).
9164 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
9165 Call gtk_window_set_resizable if HAVE_GTK3.
9166 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9167 and height if HAVE_GTK3 (Bug#8505).
9168 (scroll_bar_width_for_theme): New variable.
9169 (update_theme_scrollbar_width): New function.
9170 (xg_get_default_scrollbar_width): Move code to
9171 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
9172 (xg_initialize): Call update_theme_scrollbar_width.
9174 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
9176 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
9178 2011-06-12 Martin Rudalics <rudalics@gmx.at>
9180 * frame.c (make_frame): Call other_buffer_safely instead of
9181 other_buffer.
9183 * window.c (temp_output_buffer_show): Call display_buffer with
9184 second argument Vtemp_buffer_show_specifiers and reset latter
9185 immediately after the call.
9186 (Vtemp_buffer_show_specifiers): New variable.
9187 (auto_window_vscroll_p, next_screen_context_lines)
9188 (Vscroll_preserve_screen_position): Remove leading asterisks from
9189 doc-strings.
9191 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
9193 Fix minor problems found by GCC 4.6.0 static checking.
9194 * buffer.c (Qclone_number): Remove for now, as it's unused.
9195 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
9196 (record_buffer): Remove unused local.
9197 * frame.c (other_visible_frames, frame_buffer_list): Now static.
9198 (set_frame_buffer_list): Remove; unused.

9209 * widgetprv.h (emacsFrameClassRec): Remove decl.
9210 * window.c (delete_deletable_window): Now returns void, since it
9211 wasn't returning anything.
9212 (compare_window_configurations): Remove unused locals.
9213 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
9214 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
9215 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
9216 the same widths as pointers. This follows up on the 2011-05-06 patch.
9217 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
9218 * xterm.h: Likewise.

9231 2011-06-11 Martin Rudalics <rudalics@gmx.at>
9233 * window.c (delete_deletable_window): Re-add.
9234 (Fset_window_configuration): Rewrite to handle dead buffers and
9235 consequently deletable windows.
9236 (window_tree, Fwindow_tree): Remove. Supply functionality in
9237 window.el.
9238 (compare_window_configurations): Simplify code.
9240 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
9242 * image.c (imagemagick_load_image): Fix type mismatch.
9243 (Fimagemagick_types): Likewise.

9256 buffer list implementation.
9257 (other_buffer_safely): New function.
9258 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by

9261 if allowed.
9262 (record_buffer): Inhibit quitting and rewrite using quittable
9263 functions. Run Qbuffer_list_update_hook if allowed.
9264 (Frecord_buffer, Funrecord_buffer): New functions.

9266 Move switch-to-buffer to window.el.
9267 (bury-buffer): Move to window.el.
9268 (Vbuffer_list_update_hook): New variable.
9270 * lisp.h (other_buffer_safely): Add prototype in buffer.c
9271 section.

9274 (Fwindow_frame): Remove EXFUN.
9275 (replace_buffer_in_all_windows): Remove prototype.

9279 declaration of select_count.
9280 (Fnext_window, Fprevious_window): Rewrite doc-strings.

9292 of run_window_configuration_change_hook. Remove now obsolete
9293 declarations.
9294 (Fset_window_buffer): Rewrite doc-string.
9295 Call Qrecord_window_buffer.
9296 (keys_of_window): Move binding for other-window to window.el.
9298 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
9300 * dispextern.h (struct image): Replace data member, whose int_val
9301 and ptr_val fields were not used by anything, with a single
9302 lisp_val object.

9370 size_window, window_fixed_size_p, enlarge_window, delete_window.
9371 Remove static from declaration of Qdelete_window, it's
9372 temporarily needed by Fbury_buffer.
9373 (replace_window): Don't assign orig_top_line and
9374 orig_total_lines.
9375 (Fdelete_window, delete_window): Remove. Window deletion is
9376 handled by window.el.
9377 (window_loop): Remove DELETE_OTHER_WINDOWS case.
9378 Replace Fdelete_window calls with calls to Qdelete_window.
9379 (Fdelete_other_windows): Remove. Deleting other windows is
9380 handled by window.el.

9784 * gnutls.c: Use Emacs's memory allocators.
9785 Without this change, the gnutls library would invoke malloc etc.
9786 directly, which causes problems on non-SYNC_INPUT hosts, and which
9787 runs afoul of improving memory_full behavior. (Bug#8761)
9788 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
9789 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
9790 xfree instead of the default malloc, realloc, free.
9791 (Fgnutls_boot): No need to check for memory allocation failure,
9792 since xmalloc does that for us.

9818 * ccl.c (ccl_driver):
9819 Check for overflow when converting EMACS_INT to int.
9820 * fns.c, image.c: Remove unnecessary static decls that would otherwise
9821 need to be updated by these changes.
9822 * fns.c (make_hash_table, maybe_resize_hash_table):
9823 Check for integer overflow with large hash tables.
9824 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
9825 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
9826 (SXHASH_REDUCE): New macro.
9827 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
9828 Use it instead of discarding useful hash info with large hash values.
9829 (sxhash_float): New function.
9830 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
9831 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
9832 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
9833 Rewrite to use FIXNUM_BITS, as this simplifies things.
9834 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
9835 Adjust signatures to match updated version of code.
9836 (consing_since_gc): Now EMACS_INT, since a single hash table can
9837 use more than INT_MAX bytes.
9839 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
9841 Make it possible to build with GCC-4.6+ -O2 -flto.
9843 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
9845 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
9847 * minibuf.c (get_minibuffer, read_minibuf_unwind):
9848 Call minibuffer-inactive-mode.
9850 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
9852 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
9853 Update dependencies.
9855 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9857 * data.c (init_data): Remove code for UTS, this system is not
9858 supported anymore.
9860 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9862 Don't force ./temacs to start in terminal mode.
9864 * frame.c (make_initial_frame): Initialize faces in all cases, not
9865 only when CANNOT_DUMP is defined.
9866 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
9868 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9870 * dispnew.c (add_window_display_history): Use const for the string
9871 pointer. Remove declaration, not needed.
9873 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9875 Use 'inline', not 'INLINE'.
9876 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
9877 * alloc.c, fontset.c (INLINE): Remove.
9878 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
9879 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
9880 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
9881 * gmalloc.c (register_heapinfo): Use inline unconditionally.
9882 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
9884 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9886 Make it possible to run ./temacs.
9888 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
9889 syms_of_callproc does the same thing. Remove test for
9890 "initialized", do it in the caller.
9891 * emacs.c (main): Avoid calling set_initial_environment when dumping.
9893 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
9895 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
9896 (read_minibuf): Use get_minibuffer.
9897 (syms_of_minibuf): Use DEFSYM.
9898 (Qmetadata): New var.
9899 * data.c (Qbuffer): Don't make it static.
9900 (syms_of_data): Use DEFSYM.
9902 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9904 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
9905 (CCL_CODE_MIN): New macro.
9907 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
9909 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
9911 * eval.c (Qdebug): Now static.
9912 * lisp.h (Qdebug): Remove decl. This reverts a part of the
9913 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
9914 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
9916 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9918 * image.c: Various fixes to ImageMagick code comments.
9919 (Fimagemagick_types): Doc fix.
9921 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
9923 Minor fixes prompted by GCC 4.6.0 warnings.
9925 * xselect.c (converted_selections, conversion_fail_tag): Now static.
9927 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
9928 (x_clipboard_manager_save_all): Move extern decl to ...
9929 * xterm.h: ... here, so that it can be checked for consistency.
9931 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9933 * xselect.c (x_clipboard_manager_save_frame)
9934 (x_clipboard_manager_save_all): New functions.
9935 (Fx_clipboard_manager_save): Lisp function deleted.
9937 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
9938 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
9940 * xterm.h: Update prototype.
9942 2011-05-28 William Xu <william.xwl@gmail.com>
9944 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
9945 exiting (Bug#8239).
9947 2011-05-28 Jim Meyering <meyering@redhat.com>
9949 Avoid a sign-extension bug in crypto_hash_function.
9950 * fns.c (to_uchar): Define.
9951 (crypto_hash_function): Use it to convert some newly-signed
9952 variables to unsigned, to avoid sign-extension bugs. For example,
9953 without this change, (md5 "truc") would evaluate to
9954 45723a2aff78ff4fff7fff1114760e62 rather than the expected
9955 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
9956 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
9958 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9960 Integer overflow fixes.
9962 * dbusbind.c: Serial number integer overflow fixes.
9963 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
9964 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
9965 to hold a serial number that is too large for a fixnum.
9966 (Fdbus_method_return_internal, Fdbus_method_error_internal):
9967 Check for serial numbers out of range. Decode any serial number
9968 that was so large that it became a float. (Bug#8722)
9970 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
9971 (Fdbus_call_method, Fdbus_call_method_asynchronously):
9972 Use XFASTINT rather than XUINT when numbers are nonnegative.
9973 (xd_append_arg, Fdbus_method_return_internal):
9974 (Fdbus_method_error_internal): Likewise. Also, for unsigned
9975 arguments, check that Lisp number is nonnegative, rather than
9976 silently wrapping negative numbers around. (Bug#8722)
9977 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
9978 (Bug#8722)
9980 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
9982 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
9984 ccl: Add integer overflow checks.
9985 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
9986 (IN_INT_RANGE): New macros.
9987 (ccl_driver): Use them to check for integer overflow when
9988 decoding a CCL program. Many of the new checks are whether XINT (x)
9989 fits in int; it doesn't always, on 64-bit hosts. The new version
9990 doesn't catch all possible integer overflows, but it's an
9991 improvement. (Bug#8719)
9993 * alloc.c (make_event_array): Use XINT, not XUINT.
9994 There's no need for unsigned here.
9996 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
9997 This follows up to the 2011-05-06 change that substituted uintptr_t
9998 for EMACS_INT. This case wasn't caught back then.
10000 Rework Fformat to avoid integer overflow issues.
10001 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10002 now (part of C89). Include <verify.h>.
10003 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10004 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10005 (Fformat): Avoid the prepass trying to compute sizes; it was only
10006 approximate and thus did not catch overflow reliably. Instead, walk
10007 through the format just once, formatting and computing sizes as we go,
10008 checking for integer overflow at every step, and allocating a larger
10009 buffer as needed. Keep track separately whether the format is
10010 multibyte. Keep only the most-recently calculated precision, rather
10011 than them all. Record whether each argument has been converted to
10012 string. Use EMACS_INT, not int, for byte and char and arg counts.
10013 Support field widths and precisions larger than INT_MAX. Avoid
10014 sprintf's undefined behavior with conversion specifications such as %#d
10015 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10016 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10017 formatting out-of-range floating point numbers with int
10018 formats. (Bug#8668)
10020 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10022 * data.c: Avoid integer truncation in expressions involving floats.
10023 * data.c: Include <intprops.h>.
10024 (arith_driver): When there's an integer overflow in an expression
10025 involving floating point, convert the integers to floating point
10026 so that the resulting value does not suffer from catastrophic
10027 integer truncation. For example, on a 64-bit host (* 4
10028 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10029 Do not rely on undefined behavior after integer overflow.
10031 merge count_size_as_multibyte, parse_str_to_multibyte
10032 * character.c, character.h (count_size_as_multibyte):
10033 Rename from parse_str_to_multibyte; all uses changed.
10034 Check for integer overflow.
10035 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10036 since it's now a duplicate of the other. This is more of
10037 a character than a buffer op, so better that it's in character.c.
10038 * fns.c, print.c: Adjust to above changes.
10040 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10042 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10044 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10046 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10047 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10048 (x_clipboard_manager_save): Now static.
10049 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10051 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10052 (crypto_hash_function): Now static.
10053 Fix pointer signedness problems. Avoid unnecessary initializations.
10055 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10057 * termhooks.h (Vselection_alist): Make it terminal-local.
10059 * terminal.c (create_terminal): Initialize it.
10061 * xselect.c: Support for clipboard managers.
10062 (Vselection_alist): Move to termhooks.h as terminal-local var.
10063 (LOCAL_SELECTION): New macro.
10064 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10065 (symbol_to_x_atom): Remove gratuitous arg.
10066 (x_handle_selection_request, lisp_data_to_selection_data)
10067 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10068 (x_own_selection, x_get_local_selection, x_convert_selection):
10069 New arg, specifying work frame. Use terminal-local Vselection_alist.
10070 (some_frame_on_display): Delete unused function.
10071 (Fx_own_selection_internal, Fx_get_selection_internal)
10072 (Fx_disown_selection_internal, Fx_selection_owner_p)
10073 (Fx_selection_exists_p): New optional frame arg.
10074 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10075 (x_handle_selection_clear): Don't treat other terminals with the
10076 same keyboard specially. Use the terminal-local Vselection_alist.
10077 (x_clear_frame_selections): Use Frun_hook_with_args.
10079 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10081 * xterm.h: Add support for those atoms.
10083 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10085 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10086 (converted_selections, conversion_fail_tag): New global variables.
10087 (x_selection_request_lisp_error): Free the above.
10088 (x_get_local_selection): Remove unnecessary code.
10089 (x_reply_selection_request): Args changed; handle arbitrary array
10090 of converted selections stored in converted_selections.
10091 Separate the XChangeProperty and SelectionNotify steps.
10092 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10093 (x_convert_selection): New function.
10094 (x_handle_selection_event): Simplify.
10095 (x_get_foreign_selection): Don't ignore incoming requests while
10096 waiting for an answer; this will fail when we implement
10097 SAVE_TARGETS, and seems unnecessary anyway.
10098 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10099 (Vx_sent_selection_functions): Doc fix.
10101 2011-05-26 Leo Liu <sdl.web@gmail.com>
10103 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10105 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10107 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10109 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10110 for fringe update if it has periodic bitmap.
10111 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10112 and fringe_bitmap_periodic_p.
10114 * fringe.c (get_fringe_bitmap_data): New function.
10115 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10116 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10117 row. Mark glyph row for fringe update if periodicity changed.
10119 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10120 for fringe update unless it has periodic bitmap.
10122 2011-05-25 Kenichi Handa <handa@m17n.org>
10124 * xdisp.c (get_next_display_element): Set correct it->face_id for
10125 a static composition.
10127 2011-05-24 Leo Liu <sdl.web@gmail.com>
10129 * deps.mk (fns.o):
10130 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10132 * fns.c (crypto_hash_function, Fsha1): New function.
10133 (Fmd5): Use crypto_hash_function.
10134 (syms_of_fns): Add Ssha1.
10136 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10138 * gnutls.c: Remove unused macros.
10139 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10140 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10141 Remove macros that are defined and never used.
10142 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10144 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10146 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10147 (Fx_get_selection_internal): Minor cleanup.
10148 (Fx_own_selection_internal): Rename arguments for consistency with
10149 select.el.
10151 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10153 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10155 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10157 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10159 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10161 * dispnew.c (scrolling_window): Don't exclude the case that the
10162 last enabled row in the desired matrix touches the bottom boundary.
10164 2011-05-21 Glenn Morris <rgm@gnu.org>
10166 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10167 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10168 and add some more files.
10170 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10172 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10173 report_file_error introduced by the change from 2011-05-07.
10175 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10177 * systime.h (Time): Define only if emacs is defined.
10178 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10179 where the include path doesn't have X11/X.h by default. See
10180 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10182 2011-05-20 Kenichi Handa <handa@m17n.org>
10184 * composite.c (find_automatic_composition): Fix previous change.
10186 2011-05-20 Glenn Morris <rgm@gnu.org>
10188 * lisp.mk: New file, split from Makefile.in.
10189 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10190 (shortlisp): Remove.
10191 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10193 2011-05-19 Glenn Morris <rgm@gnu.org>
10195 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10196 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10197 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10198 (lisp): Set the order to that of loadup.el.
10199 (shortlisp): Make it a copy of $lisp.
10200 (SOME_MACHINE_LISP): Remove.
10201 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10202 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10204 2011-05-18 Kenichi Handa <handa@m17n.org>
10206 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10207 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10208 (find_automatic_composition): Mostly rewrite for efficiency.
10210 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10212 * makefile.w32-in: Update dependencies.
10214 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10216 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10217 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10219 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10221 Fix some integer overflow issues, such as string length overflow.
10223 * insdel.c (count_size_as_multibyte): Check for string overflow.
10225 * character.c (lisp_string_width): Check for string overflow.
10226 Use EMACS_INT, not int, for string indexes and lengths; in
10227 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10228 the resulting string length overflows an EMACS_INT; instead,
10229 report a string overflow if no precision given. When checking for
10230 precision exhaustion, use a check that cannot possibly have
10231 integer overflow. (Bug#8675)
10232 * character.h (lisp_string_width): Adjust to new signature.
10234 * alloc.c (string_overflow): New function.
10235 (Fmake_string): Use it. This doesn't change behavior, but saves
10236 a few bytes and will simplify future changes.
10237 * character.c (string_escape_byte8): Likewise.
10238 * lisp.h (string_overflow): New decl.
10240 Fixups, following up to the user-interface timestamp change.
10241 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10242 for UI timestamps, instead of unsigned long.
10243 * msdos.c (mouse_get_pos): Likewise.
10244 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10245 * w32gui.h (Time): Define by including "systime.h" rather than by
10246 declaring it ourselves. (Bug#8664)
10248 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10249 * image.c (clear_image_cache): Likewise.
10251 * term.c (term_mouse_position): Don't assume time_t wraparound.
10253 Be more systematic about user-interface timestamps.
10254 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10255 and sometimes 'EMACS_UINT', to represent these timestamps.
10256 This change causes it to use 'Time' uniformly, as that's what X uses.
10257 This makes the code easier to follow, and makes it easier to catch
10258 integer overflow bugs such as Bug#8664.
10259 * frame.c (Fmouse_position, Fmouse_pixel_position):
10260 Use Time, not unsigned long, for user-interface timestamps.
10261 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10262 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10263 * keyboard.h (last_event_timestamp): Likewise.
10264 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10265 * menu.h (xmenu_show): Likewise.
10266 * term.c (term_mouse_position): Likewise.
10267 * termhooks.h (struct input_event.timestamp): Likewise.
10268 (struct terminal.mouse_position_hook): Likewise.
10269 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10270 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10271 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10272 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10273 what it was before.
10274 * menu.h, termhooks.h: Include "systime.h", for Time.
10276 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10277 Don't assume that the difference between two unsigned long values
10278 can fit into an integer. At this point, we know button_down_time
10279 <= event->timestamp, so the difference must be nonnegative, so
10280 there's no need to cast the result if double-click-time is
10281 nonnegative, as it should be; check that it's nonnegative, just in
10282 case. This bug is triggered when events are more than 2**31 ms
10283 apart (about 25 days). (Bug#8664)
10285 * xselect.c (last_event_timestamp): Remove duplicate decl.
10286 (x_own_selection): Remove needless cast to unsigned long.
10288 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10289 that always fit in int. Use a sentinel instead of a counter, to
10290 avoid a temp and to allay GCC's concerns about possible int overflow.
10291 * frame.h (struct frame): Use int for menu_bar_items_used
10292 instead of EMACS_INT, since it always fits in int.
10294 * menu.c (grow_menu_items): Check for int overflow.
10296 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10298 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10299 Before, the code was not consistent. These values cannot exceed
10300 2**31 - 1 so there's no need to make them unsigned.
10301 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10302 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10303 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10304 as modifiers.
10305 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10307 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10308 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10309 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10310 presumably because the widths might not match.
10312 * window.c (size_window): Avoid needless test at loop start.
10314 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10316 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10318 2011-05-12 Drew Adams <drew.adams@oracle.com>
10320 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10322 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10324 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10325 `width' to `bar_area_x' and `bar_area_width', respectively.
10326 (x_scroll_run): Take account of fringe background extension.
10328 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10329 Rename local vars `left' and `width' to `bar_area_x' and
10330 `bar_area_width', respectively.
10331 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10332 background extension.
10334 2011-05-10 Jim Meyering <meyering@redhat.com>
10336 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10338 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10340 * image.c (Finit_image_library): Return t for built-in image types,
10341 like pbm and xbm. (Bug#8640)
10343 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10345 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10347 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10349 * w32console.c (Fset_screen_color): Doc fix.
10350 (Fget_screen_color): New function.
10351 (syms_of_ntterm): Defsubr it.
10353 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10354 unlink the temporary file if Fcall_process didn't create it in the
10355 first place.
10356 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10357 child process will be redirected to a file specified with `:file'.
10358 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10359 cue to call_process_cleanup not to close that handle.
10361 2011-05-07 Ben Key <bkey76@gmail.com>
10363 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10364 one of two shell specific rules, either bootstrap-temacs-CMD or
10365 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10366 to the previous implementation of the bootstrap-temacs rule.
10367 The bootstrap-temacs-CMD rule is similar to the previous
10368 implementation of the bootstrap-temacs rule except that it
10369 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10370 variable.
10372 These changes, along with some changes to nt/configure.bat,
10373 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10374 earlier fix to add support for --cflags and --ldflags options
10375 that include quotes so that it works whether make uses cmd or
10376 sh as the shell.
10378 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10380 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10381 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10382 is a constant.
10383 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10384 a string. Handle both cases.
10385 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10386 (Fdbus_register_method): Use Qinvalid_function.
10388 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10390 * makefile.w32-in: Update dependencies.
10391 (LISP_H): Add inttypes.h and stdin.h.
10392 (PROCESS_H): Add unistd.h.
10394 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10396 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10397 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10399 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10401 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10403 * term.c (vfatal): Remove stray call to va_end.
10404 It's not needed and the C Standard doesn't allow it here anyway.
10406 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10407 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10409 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10410 bytes.
10412 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10414 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10416 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10418 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10420 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10422 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10423 * charset.c (Fdefine_charset_internal): Don't initialize
10424 charset.code_space[15]. The value was garbage, on hosts with
10425 32-bit int (Bug#8600).
10427 * lread.c (read_integer): Be more consistent with string-to-number.
10428 Use string_to_number to do the actual conversion; this avoids
10429 rounding errors and fixes some other screwups. Without this fix,
10430 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10431 (digit_to_number): Move earlier, for benefit of read_integer.
10432 Return -1 if the digit is out of range for the base, -2 if it is
10433 not a digit in any supported base. (Bug#8602)
10435 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10437 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10438 to match comment at start of function. This also removes a
10439 GCC warning about overflow in a 32+64-bit port.
10441 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10443 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10444 Reported by Stefan Monnier in
10445 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10446 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10447 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10449 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10450 (EMACS_UINTPTR): Likewise, with uintptr_t.
10452 * lisp.h: Prefer 64-bit EMACS_INT if available.
10453 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10454 on 32-bit hosts that have 64-bit int, so that they can access
10455 large files.
10456 However, temporarily disable this change unless the temporary
10457 symbol WIDE_EMACS_INT is defined.
10459 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10461 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10462 This removes an assumption that EMACS_INT and long are the same
10463 width as pointers. The assumption is true for Emacs porting targets
10464 now, but we want to make other targets possible.
10465 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10466 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10467 In the rest of the code, change types of integers that hold casted
10468 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10469 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10470 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10471 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10472 No need to cast type when ORing.
10473 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10474 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10475 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10476 assume EMACS_INT is the same width as char *.
10477 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10478 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10479 Remove no-longer-needed casts.
10480 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10481 (xg_tool_bar_help_callback, xg_make_tool_item):
10482 Use EMACS_INTPTR to hold an integer
10483 that will be cast to void *; this can avoid a GCC warning
10484 if EMACS_INT is not the same width as void *.
10485 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10486 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10487 (current_message_1, set_message_1):
10488 Use a local to convert to proper width without a cast.
10489 * xmenu.c (dialog_selection_callback): Likewise.
10491 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10492 Also, don't assume VALBITS / RAND_BITS is less than 5,
10493 and don't rely on undefined behavior when shifting a 1 left into
10494 the sign bit.
10495 * lisp.h (get_random): Change signature to match.
10497 * lread.c (hash_string): Use size_t, not int, for hash computation.
10498 Normally we prefer signed values; but hashing is special, because
10499 it's better to use unsigned division on hash table sizes so that
10500 the remainder is nonnegative. Also, size_t is the natural width
10501 for hashing into memory. The previous code used 'int', which doesn't
10502 retain enough info to hash well into very large tables.
10503 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10505 * dbusbind.c: Don't possibly lose pointer info when converting.
10506 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10507 Use XPNTR rather than XHASH, so that the high-order bits of
10508 the pointer aren't lost when converting through void *.
10510 * eval.c (Fautoload): Don't double-shift a pointer.
10512 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
10514 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10516 * gnutls.c (DEF_GNUTLS_FN):
10517 * image.c (DEF_IMGLIB_FN): Make function pointers static.
10519 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
10521 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
10522 marker. (Bug#8610)
10524 2011-05-05 Eli Zaretskii <eliz@gnu.org>
10526 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
10527 New version that can reserve upto 2GB of heap space.
10529 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
10531 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
10533 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
10535 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
10536 `gnutls_certificate_set_x509_key_file'.
10538 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
10540 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
10541 Update dependencies.
10543 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10545 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
10546 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
10547 Remove unused parameter `fildes'.
10548 * process.c (read_process_output, send_process): Don't pass it.
10550 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10552 Fix previous change: the library cache is defined in w32.c.
10553 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
10554 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
10556 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10558 Implement dynamic loading of GnuTLS on Windows.
10560 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
10561 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
10562 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10563 Declare.
10565 * gnutls.c (Qgnutls_dll): Define.
10566 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
10567 (gnutls_*): Declare function pointers.
10568 (init_gnutls_functions): New function to initialize function pointers.
10569 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
10570 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
10571 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
10572 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
10573 (emacs_gnutls_write, emacs_gnutls_read)
10574 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
10575 (Fgnutls_available_p): New function.
10576 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
10577 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
10578 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
10580 * image.c: Include w32.h.
10581 (Vimage_type_cache): Delete.
10582 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
10583 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
10584 (w32_delayed_load): Move to w32.c.
10586 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
10588 * w32.c (QCloaded_from, Vlibrary_cache): Define.
10589 (w32_delayed_load): Move from image.c. When loading a library, record
10590 its filename in the :loaded-from property of the library id.
10591 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
10592 Initialize and staticpro them.
10593 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
10595 * process.c: Include lisp.h before w32.h, not after.
10596 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10597 instead of gnutls_record_check_pending.
10599 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10601 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10603 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
10604 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
10605 as passed in.
10607 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
10609 * xterm.c (x_set_frame_alpha): Do not set property on anything
10610 else than FRAME_X_OUTER_WINDOW (Bug#8608).
10612 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10614 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
10616 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
10618 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
10619 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
10620 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

10623 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
10624 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
10625 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
10626 (Qgnutls_bootprop_callbacks_verify): Make static.
10628 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
10630 * callproc.c: Indentation fixup.
10632 * sysdep.c (wait_for_termination_1): Make static.
10633 (wait_for_termination, interruptible_wait_for_termination):
10634 Move after wait_for_termination_1.
10636 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
10638 * sysdep.c (interruptible_wait_for_termination): New function
10639 which is like wait_for_termination, but allows keyboard
10640 interruptions.
10642 * callproc.c (Fcall_process): Add (:file "file") as an option for
10643 the STDOUT buffer.
10644 (Fcall_process_region): Ditto.
10646 2011-04-30 Eli Zaretskii <eliz@gnu.org>
10648 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
10649 rather than `XVECTOR (FOO)->size'.
10651 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10652 inttypes.h, as a gnulib replacement is used if it not available in
10653 system headers.
10655 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10657 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
10658 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
10659 of MOST_POSITIVE_FIXNUM. (Bug#8528)
10661 * coding.c (coding_alloc_by_realloc): Error out if destination
10662 will grow beyond MOST_POSITIVE_FIXNUM.
10663 (decode_coding_emacs_mule): Abort if there isn't enough place in
10664 charbuf for the composition carryover bytes. Reserve an extra
10665 space for up to 2 characters produced in a loop.
10666 (decode_coding_iso_2022): Abort if there isn't enough place in
10667 charbuf for the composition carryover bytes.
10669 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10671 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
10672 aborting when %lld or %lll format is passed.
10673 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
10674 %llo or %llx format is passed. (Bug#8545)
10676 * window.c (window_scroll_line_based): Use a marker instead of
10677 simple variables to record original value of point. (Bug#7952)
10679 * doprnt.c (doprnt): Fix the case where a multibyte sequence
10680 produced by %s or %c overflows available buffer space. (Bug#8545)
10682 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10684 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
10685 (SIZE_MAX): Move defn after all includes, as they might #define it.
10687 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10689 * w32.c (init_environment): Warn about defaulting HOME to C:\.
10691 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10693 * keyboard.c (Qdelayed_warnings_hook): Define.
10694 (command_loop_1): Run `delayed-warnings-hook'
10695 if Vdelayed_warnings_list is non-nil.
10696 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
10697 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
10699 2011-04-28 Eli Zaretskii <eliz@gnu.org>
10701 * doprnt.c (doprnt): Don't return value smaller than the buffer
10702 size if the message was truncated. (Bug#8545).
10704 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10706 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
10707 (Fx_window_property): #if-0 the whole functions, not just the bodies.
10709 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10711 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
10713 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
10715 * makefile.w32-in: Update dependencies.
10717 2011-04-27 Eli Zaretskii <eliz@gnu.org>
10719 Improve `doprnt' and its usage. (Bug#8545)
10720 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
10721 `format_end'. Remove support for %l as a conversion specifier.
10722 Don't use xrealloc. Improve diagnostics when the %l size modifier
10723 is used. Update the commentary.
10725 * eval.c (verror): Simplify calculation of size_t.
10727 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
10728 messages.
10730 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
10732 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10733 change.
10735 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10737 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10738 This makes this file independent of the recent pseudovector change.
10740 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
10742 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10744 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10745 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10746 Remove unused local.
10747 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10749 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
10750 GCC 4.6.0 optimizes based on type-based alias analysis.
10751 For example, if b is of type struct buffer * and v of type struct
10752 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10753 != &v->size, and therefore "v->size = 1; b->size = 2; return
10754 v->size;" must therefore return 1. This assumption is incorrect
10755 for Emacs, since it type-puns struct Lisp_Vector * with many other
10756 types. To fix this problem, this patch adds a new type struct
10757 vectorlike_header that documents the constraints on layout of vectors
10758 and pseudovectors, and helps optimizing compilers not get fooled
10759 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
10760 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10761 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10762 the size member.
10763 (XSETPVECTYPE): Rewrite in terms of new macro.
10764 (XSETPVECTYPESIZE): New macro, specifying both type and size.
10765 This is a bit clearer, and further avoids the possibility of
10766 undesirable aliasing.
10767 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10768 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10769 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10770 since Lisp_Subr is a special case (no "next" field).
10771 (ASIZE): Now uses header.size rather than size.
10772 All previous uses of XVECTOR (foo)->size replaced to use this macro,
10773 to avoid the hassle of writing XVECTOR (foo)->header.size.
10774 (struct vectorlike_header): New type.
10775 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10776 object, to help avoid aliasing.
10777 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10778 (SUBRP): Likewise, since Lisp_Subr is a special case.
10779 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10780 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10781 (struct Lisp_Hash_Table): Combine first two members into a single
10782 struct vectorlike_header member. All uses of "size" and "next" members
10783 changed to be "header.size" and "header.next".
10784 * buffer.h (struct buffer): Likewise.
10785 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
10786 * frame.h (struct frame): Likewise.
10787 * process.h (struct Lisp_Process): Likewise.
10788 * termhooks.h (struct terminal): Likewise.
10789 * window.c (struct save_window_data, struct saved_window): Likewise.
10790 * window.h (struct window): Likewise.
10791 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
10792 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
10793 * buffer.c (init_buffer_once): Likewise.
10794 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
10795 special case.
10796 * process.c (Fformat_network_address): Use local var for size,
10797 for brevity.
10799 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
10801 Make the Lisp reader and string-to-float more consistent (Bug#8525)
10802 * data.c (atof): Remove decl; no longer used or needed.
10803 (digit_to_number): Move to lread.c.
10804 (Fstring_to_number): Use new string_to_number function, to be
10805 consistent with how the Lisp reader treats infinities and NaNs.
10806 Do not assume that floating-point numbers represent EMACS_INT
10807 without losing information; this is not true on most 64-bit hosts.
10808 Avoid double-rounding errors, by insisting on integers when
10809 parsing non-base-10 numbers, as the documentation specifies.
10810 * lisp.h (string_to_number): New decl, replacing ...
10811 (isfloat_string): Remove.
10812 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
10813 (read1): Do not accept +. and -. as integers; this
10814 appears to have been a coding error. Similarly, do not accept
10815 strings like +-1e0 as floating point numbers. Do not report
10816 overflow for integer overflows unless the base is not 10 which
10817 means we have no simple and reliable way to continue.
10818 Break out the floating-point parsing into a new
10819 function string_to_number, so that Fstring_to_number parses
10820 floating point numbers consistently with the Lisp reader.
10821 (digit_to_number): Move here from data.c. Make it static inline.
10822 (E_CHAR, EXP_INT): Remove, replacing with ...
10823 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
10824 (string_to_number): New function, replacing isfloat_string.
10825 This function checks for valid syntax and produces the resulting
10826 Lisp float number too. Rework it so that string-to-number
10827 no longer mishandles examples like "1.0e+". Use strtoumax,
10828 so that overflow for non-base-10 numbers is reported only when
10829 there's no portable and simple way to convert to floating point.
10831 * textprop.c (set_text_properties_1): Rewrite for clarity,
10832 and to avoid GCC warning about integer overflow.
10834 * intervals.h (struct interval): Use EMACS_INT for members
10835 where EMACS_UINT might cause problems. See
10836 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
10837 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
10838 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
10839 All uses changed.
10840 (offset_intervals): Tell GCC not to worry about length overflow
10841 when negating a negative length.
10843 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
10844 (overrun_check_free): Likewise.
10846 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
10847 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
10848 word size.
10850 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10851 (gnutls_make_error): Rename local to avoid shadowing.
10852 (gnutls_emacs_global_deinit): ifdef out; not used.
10853 (Fgnutls_boot): Use const for pointer to readonly storage.
10854 Comment out unused local. Fix pointer signedness problems.
10856 * lread.c (openp): Don't stuff size_t into an 'int'.
10857 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
10858 about possible signed overflow.
10860 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10861 (GDK_KEY_g): Don't define if already defined.
10862 (xg_prepare_tooltip): Avoid pointer signedness problem.
10863 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
10865 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
10866 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
10868 * xfns.c (Fx_window_property): Simplify a bit,
10869 to make a bit faster and to avoid GCC 4.6.0 warning.
10870 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
10872 * fns.c (internal_equal): Don't assume size_t fits in int.
10874 * alloc.c (compact_small_strings): Tighten assertion a little.
10876 Replace pEd with more-general pI, and fix some printf arg casts.
10877 * lisp.h (pI): New macro, generalizing old pEd macro to other
10878 conversion specifiers. For example, use "...%"pI"d..." rather
10879 than "...%"pEd"...".
10880 (pEd): Remove. All uses replaced with similar uses of pI.
10881 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
10882 * alloc.c (check_pure_size): Don't overflow by converting size to int.
10883 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
10884 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
10885 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
10886 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
10887 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
10888 64-bit hosts.
10889 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
10890 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
10891 * print.c (safe_debug_print, print_object): Likewise.
10892 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
10893 to int.
10894 Use pI instead of if-then-else-abort. Use %p to avoid casts,
10895 avoiding the 0 flag, which is not portable.
10896 * process.c (Fmake_network_process): Use pI to avoid cast.
10897 * region-cache.c (pp_cache): Likewise.
10898 * xdisp.c (decode_mode_spec): Likewise.
10899 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
10900 behavior on 64-bit hosts with printf arg.
10901 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
10902 (x_stop_queuing_selection_requests): Likewise.
10903 (x_get_window_property): Don't truncate byte count to an 'int'
10904 when tracing.
10906 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
10907 here, since it parses constructs like leading '-' and spaces,
10908 which are not wanted; and it overflows with large numbers.
10909 Instead, simply match F[0-9]+, which is what is wanted anyway.
10911 * alloc.c: Remove unportable assumptions about struct layout.
10912 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
10913 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
10914 (allocate_vectorlike, make_pure_vector): Use the new macros,
10915 plus offsetof, to remove unportable assumptions about struct layout.
10916 These assumptions hold on all porting targets that I know of, but
10917 they are not guaranteed, they're easy to remove, and removing them
10918 makes further changes easier.
10920 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
10921 This doesn't fix a bug but makes the code clearer.
10922 (string_overrun_cookie): Now const. Use initializers that
10923 don't formally overflow signed char, to avoid warnings.
10924 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
10925 can cause Emacs to crash when string overrun checking is enabled.
10926 (allocate_buffer): Don't assume sizeof (struct buffer) is a
10927 multiple of sizeof (EMACS_INT); it need not be, if
10928 alignof(EMACS_INT) < sizeof (EMACS_INT).
10929 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
10931 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
10933 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
10935 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
10937 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
10938 supposed to be handshaking. (Bug#8556)
10939 Reported by Paul Eggert <eggert@cs.ucla.edu>.
10941 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
10943 * lisp.h (Qdebug): List symbol.
10944 * eval.c (Qdebug): Restore global linkage.
10945 * keyboard.c (debug-on-event): New variable.
10946 (handle_user_signal): Break into debugger when debug-on-event
10947 matches the current signal symbol.
10949 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
10951 * alloc.c (check_sblock, check_string_bytes)
10952 (check_string_free_list): Convert to standard C.
10954 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
10956 * w32.c (emacs_gnutls_push): Fix typo.
10958 2011-04-25 Eli Zaretskii <eliz@gnu.org>
10960 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
10961 "cast to pointer from integer of different size".
10963 Improve doprnt and its use in verror. (Bug#8545)
10964 * doprnt.c (doprnt): Document the set of format control sequences
10965 supported by the function. Use SAFE_ALLOCA instead of always
10966 using `alloca'.
10968 * eval.c (verror): Don't limit the buffer size at size_max-1, that
10969 is one byte too soon. Don't use xrealloc; instead xfree and
10970 xmalloc anew.
10972 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
10974 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
10975 callbacks stage.
10977 * gnutls.c: Renamed global_initialized to
10978 gnutls_global_initialized. Added internals for the
10979 :verify-hostname-error, :verify-error, and :verify-flags
10980 parameters of `gnutls-boot' and documented those parameters in the
10981 docstring. Start callback support.
10982 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
10983 unless a fatal error occurred. Call gnutls_alert_send_appropriate
10984 on error. Return error code.
10985 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
10986 (emacs_gnutls_read): Likewise.
10987 (Fgnutls_boot): Return handshake error code.
10988 (emacs_gnutls_handle_error): New function.
10989 (wsaerror_to_errno): Likewise.

10992 (emacs_gnutls_push): Likewise.
10994 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
10995 (emacs_gnutls_push): Likewise.
10997 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
10999 * process.c (wait_reading_process_output): Check if GnuTLS
11000 buffered some data internally if no FDs are set for TLS
11001 connections.

11010 display_replaced_before_p argument into display_replaced_p, to
11011 make it consistent with the commentary. Fix typos in the
11012 commentary.
11014 * textprop.c (syms_of_textprop): Remove dead code.
11015 (copy_text_properties): Delete obsolete commentary about an
11016 interface that was deleted long ago. Fix typos in the description
11017 of arguments.

11020 to changes in oldXMenu/XMenu.h from 2011-04-16.
11021 <menu_help_message, prev_menu_help_message>: Constify.
11022 (IT_menu_make_room): menu->help_text is now `const char **';
11023 adjust.
11025 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
11026 to changes in oldXMenu/XMenu.h from 2011-04-16.
11027 (struct XMenu): Declare `help_text' `const char **'.
11029 * xfaces.c <Qunspecified>: Make extern again.
11031 * syntax.c: Include sys/types.h before including regex.h, as
11032 required by POSIX.
11034 * doc.c (get_doc_string): Improve the format passed to `error'.
11036 * doprnt.c (doprnt): Improve commentary.
11038 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
11040 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
11041 them with etags.
11043 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
11044 changes in globals.h immediately force recompilation.
11045 (TAGS): Depend on $(CURDIR)/m/intel386.h and
11046 $(CURDIR)/s/ms-w32.h.
11047 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
11049 * character.c (Fchar_direction): Function deleted.
11050 (syms_of_character): Don't defsubr it.
11051 <char-direction-table>: Deleted.
11053 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11055 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
11056 * doprnt.c: Include limits.h.
11057 (SIZE_MAX): New macro.
11058 (doprnt): Return a size_t value. 2nd arg is now size_t.
11059 Many local variables are now size_t instead of int or unsigned.
11060 Improve overflow protection. Support `l' modifier for integer
11061 conversions. Support %l conversion. Don't assume an EMACS_INT
11062 argument for integer conversions and for %c.
11064 * lisp.h (doprnt): Restore prototype.
11066 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
11067 $(SRC)/character.h.
11069 * Makefile.in (base_obj): Add back doprnt.o.
11071 * deps.mk (doprnt.o): Add back prerequisites.
11072 (callint.o): Depend on character.h.
11074 * eval.c (internal_lisp_condition_case): Include the handler
11075 representation in the error message.
11076 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
11077 when breaking from the loop.
11079 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
11081 * callint.c (Fcall_interactively): When displaying error message
11082 about invalid control letter, pass the character's codepoint, not
11083 a pointer to its multibyte form. Improve display of the character
11084 in octal and display also its hex code.
11086 * character.c (char_string): Use %x to display the (unsigned)
11087 codepoint of an invalid character, to avoid displaying a bogus
11088 negative value.
11090 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11091 `error', not SYMBOL_NAME itself.
11093 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
11094 character arguments to `error'.
11096 * charset.c (check_iso_charset_parameter): Fix incorrect argument
11097 to `error' in error message about FINAL_CHAR argument. Make sure
11098 FINAL_CHAR is a character, and use %c when it is passed as
11099 argument to `error'.
11101 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11103 * s/ms-w32.h (localtime): Redirect to sys_localtime.

11649 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.

11698 * lisp.h (DEFINE_FUNC): Make sname 'static'.
11700 Make Emacs functions such as Fatom 'static' by default.
11701 This makes it easier for human readers (and static analyzers)
11702 to see whether these functions can be called from other modules.
11703 DEFUN now defines a static function. To make the function external
11704 so that it can be used in other C modules, use the new macro DEFUE.

11722 Mark functions with DEFUE instead of DEFUN,

11724 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
11725 decls for now-static functions.

11760 change. (Bug#8496)
11762 2011-04-13 Eli Zaretskii <eliz@gnu.org>
11764 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
11765 when at ZV. (Bug#8487)
11767 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
11769 * charset.c (Fclear_charset_maps): Use xfree instead of free.
11770 (Bug#8437)

11777 * alloc.c (overrun_check_malloc, overrun_check_realloc)
11778 (overrun_check_free): Protoize.
11780 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
11782 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
11783 since callers should never pass a negative size.
11784 Change the signature to match that of plain 'read' and 'write'; see
11785 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
11786 * lisp.h: Update prototypes of emacs_write and emacs_read.
11788 2011-04-11 Eli Zaretskii <eliz@gnu.org>
11790 * xdisp.c (redisplay_window): Don't try to determine the character
11791 position of the scroll margin if the window start point w->startp
11792 is outside the buffer's accessible region. (Bug#8468)
11794 2011-04-10 Eli Zaretskii <eliz@gnu.org>
11796 Fix write-region and its subroutines for buffers > 2GB.
11797 * fileio.c (a_write, e_write): Modify declaration of arguments and
11798 local variables to support buffers larger than 2GB.
11799 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
11801 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
11802 argument, local variables, and return value.
11804 * lisp.h: Update prototypes of emacs_write and emacs_read.
11806 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
11808 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
11810 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
11812 Fix more problems found by GCC 4.6.0's static checks.
11814 * xdisp.c (vmessage): Use a better test for character truncation.
11816 * charset.c (load_charset_map): <, not <=, for optimization,
11817 and to avoid potential problems with integer overflow.
11818 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
11819 * casetab.c (set_identity, shuffle): Likewise.
11820 * editfns.c (Fformat): Likewise.
11821 * syntax.c (skip_chars): Likewise.
11823 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
11824 This also lets GCC 4.6.0 generate slightly better loop code.
11826 * callint.c (Fcall_interactively): <, not <=, for optimization.
11827 (Fcall_interactively): Count the number of arguments produced,
11828 not the number of arguments given. This is simpler and lets GCC
11829 4.6.0 generate slightly better code.
11831 * ftfont.c: Distingish more carefully between FcChar8 and char.
11832 The previous code passed unsigned char * to a functions like
11833 strlen and xstrcasecmp that expect char *, which does not
11834 conform to the C standard.
11835 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
11836 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
11837 char * when the C standard requires it.
11839 * keyboard.c (read_char): Remove unused var.
11841 * eval.c: Port to Windows vsnprintf (Bug#8435).
11842 Include <limits.h>.
11843 (SIZE_MAX): Define if the headers do not.
11844 (verror): Do not give up if vsnprintf returns a negative count.
11845 Instead, grow the buffer. This ports to Windows vsnprintf, which
11846 does not conform to C99. Problem reported by Eli Zaretskii.
11847 Also, simplify the allocation scheme, by avoiding the need for
11848 calling realloc, and removing the ALLOCATED variable.
11850 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
11852 Remove invocations of doprnt, as Emacs now uses vsnprintf.
11853 But keep the doprint source code for now, as we might revamp it
11854 and use it again (Bug#8435).
11855 * lisp.h (doprnt): Remove.
11856 * Makefile.in (base_obj): Remove doprnt.o.
11857 * deps.mk (doprnt.o): Remove.
11859 error: Print 32- and 64-bit integers portably (Bug#8435).
11860 Without this change, on typical 64-bit hosts error ("...%d...", N)
11861 was used to print both 32- and 64-bit integers N, which relied on
11862 undefined behavior.
11863 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
11864 * lisp.h (error, verror): Mark as printf-like functions.
11865 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
11866 Report overflow in size calculations when allocating printf buffer.
11867 Do not truncate output string at its first null byte.
11868 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
11869 Truncate the output at a character boundary, since vsnprintf does not
11870 do that.
11871 * charset.c (check_iso_charset_parameter): Convert internal
11872 character to string before calling 'error', since %c now has the
11873 printf meaning.
11874 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
11875 overflow when computing char to be passed to 'error'. Do not
11876 pass Lisp_Object to 'error'; pass the integer instead.
11877 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
11878 formatted with plain %d.
11880 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
11882 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
11884 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
11886 * xterm.c (x_catch_errors): Remove duplicate declaration.
11888 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
11890 * xdisp.c, lisp.h (message_nolog): Remove; unused.
11892 2011-04-10 Jim Meyering <meyering@redhat.com>
11894 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
11895 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
11896 return ssize_t not "int", and use size_t as the buffer length.
11897 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
11898 * gnutls.h: Update declarations.
11899 * process.c (read_process_output): Use ssize_t, to match.
11900 (send_process): Likewise.
11902 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11904 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
11906 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11908 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
11909 Use unsigned char, to match FcChar8 type definition.
11911 * xterm.c (handle_one_xevent):
11912 * xmenu.c (create_and_show_popup_menu):
11913 * xselect.c (x_decline_selection_request)
11914 (x_reply_selection_request): Avoid type-punned deref of X events.
11916 2011-04-09 Eli Zaretskii <eliz@gnu.org>
11918 Fix some uses of `int' instead of EMACS_INT.
11919 * search.c (string_match_1, fast_string_match)
11920 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
11921 (scan_buffer, find_next_newline_no_quit)
11922 (find_before_next_newline, search_command, Freplace_match)
11923 (Fmatch_data): Make some `int' variables be EMACS_INT.
11925 * xdisp.c (display_count_lines): 3rd argument and return value now
11926 EMACS_INT. All callers changed.
11927 (pint2hrstr): Last argument is now EMACS_INT.
11929 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
11930 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
11931 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

11934 (decode_coding_ccl, decode_coding_charset)
11935 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
11936 (decode_coding_iso_2022, decode_coding_emacs_mule)
11937 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
11938 <char_offset, last_offset>: Declare EMACS_INT.
11939 (encode_coding_utf_8, encode_coding_utf_16)
11940 (encode_coding_emacs_mule, encode_invocation_designation)
11941 (encode_designation_at_bol, encode_coding_iso_2022)
11942 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
11943 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
11944 Declare EMACS_INT.
11945 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
11946 (encode_invocation_designation): Last argument P_NCHARS is now
11947 EMACS_INT.
11948 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
11949 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
11951 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
11952 All users changed.
11954 * ccl.c (Fccl_execute_on_string): Declare some variables
11955 EMACS_INT.
11957 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

11965 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
11967 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
11969 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
11971 * keyboard.c (read_char): Call Lisp function help-form-show,
11972 instead of using internal_with_output_to_temp_buffer.
11973 (Qhelp_form_show): New var.
11974 (syms_of_keyboard): Use DEFSYM macro.
11976 * print.c (internal_with_output_to_temp_buffer): Function deleted.

11989 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
11991 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
11993 Fix more problems found by GCC 4.6.0's static checks.

11997 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
11999 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12001 * xdisp.c (vmessage): Mark as a printf-like function.
12003 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

12010 to system-supplied API.
12012 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12014 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12015 This avoids several warnings with gcc -Wstrict-overflow.
12016 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12017 directly, rather than having caller test rule sign. This avoids
12018 some unnecessary tests.
12019 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12020 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12021 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12023 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12024 (xfont_open): Avoid unnecessary tests.
12026 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12028 * composite.h, composite.c (composition_gstring_put_cache):
12029 Use EMACS_INT, not int, for length.
12031 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12032 breaking out part of COMPOSITION_DECODE_RULE.
12033 (COMPOSITION_DECODE_RULE): Use it.
12034 * composite.c (get_composition_id): Remove unused local vars,
12035 by using the new macro.
12037 * textprop.c (set_text_properties_1): Change while to do-while,
12038 since the condition is always true at first.
12040 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12041 (interval_deletion_adjustment): Return unsigned value.
12042 All uses changed.
12044 * process.c (list_processes_1, create_pty, read_process_output):
12045 (exec_sentinel): Remove vars that were set but not used.
12046 (create_pty): Remove unnecessary "volatile"s.
12047 (Fnetwork_interface_info): Avoid possibility of int overflow.
12048 (read_process_output): Do adaptive read buffering even if carryover.
12049 (read_process_output): Simplify nbytes computation if buffered.
12051 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
12053 * syntax.c (scan_words): Remove var that was set but not used.
12054 (update_syntax_table): Use unsigned instead of int.

12057 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12058 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12060 * print.c (print_error_message): Avoid int overflow.
12062 * font.c (font_list_entities): Redo for clarity,
12063 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12065 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12066 (font_score): Avoid potential overflow in diff calculation.
12068 * fns.c (substring_both): Remove var that is set but not used.
12069 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12071 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12073 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12074 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12075 can always succeed if overflow has undefined behavior.
12077 * search.c (boyer_moore, wordify): Remove vars set but not used.
12078 (wordify): Omit three unnecessary tests.
12080 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
12081 All callers changed. This avoids the need for an unused var.
12083 * casefiddle.c (casify_region): Remove var that is set but not used.
12085 * dired.c (file_name_completion): Remove var that is set but not used.

12089 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12090 (Finsert_file_contents): Remove unnecessary code checking fd.
12092 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12093 Check for integer overflow on size calculations.
12095 * buffer.c (Fprevious_overlay_change): Remove var that is set
12096 but not used.
12098 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12099 Remove vars that are set but not used.
12100 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12101 (timer_check_2): Mark vars as initialized.
12103 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12105 * image.c (lookup_image): Remove var that is set but not used.
12106 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12108 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12109 that are set but not used.
12111 * xfns.c (make_invisible_cursor): Don't return garbage
12112 if XCreateBitmapFromData fails (Bug#8410).
12114 * xselect.c (x_get_local_selection, x_handle_property_notify):
12115 Remove vars that are set but not used.
12117 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12118 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12120 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12121 Remove var that is set but not used.
12122 (scroll_bar_windows_size): Now size_t, not int.
12123 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12124 Check for overflow.
12126 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12127 (map_tty_color) [!defined MSDOS]: Likewise.
12129 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12131 * coding.c: Remove vars that are set but not used.
12132 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12133 All callers changed.
12134 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12135 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12136 (decode_coding_charset): Remove vars that are set but not used.
12138 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12139 that is set but not used.
12141 * print.c (print_object): Remove var that is set but not used.
12143 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12144 The gnulib version avoids calling malloc in the usual case,
12145 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12146 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12147 * filelock.c (current_lock_owner): Likewise.
12148 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12149 * sysdep.c: Include allocator.h, careadlinkat.h.
12150 (emacs_no_realloc_allocator): New static constant.
12151 (emacs_readlink): New function.
12152 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12153 ../lib/careadlinkat.h.
12155 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12157 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12158 first non-nil return value).
12160 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
12162 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
12163 if not defined (Bug#8403).
12165 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12167 * xdisp.c (display_count_lines): Remove parameter `start',

12169 (get_char_face_and_encoding): Remove parameter `multibyte_p',
12170 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12171 (fill_stretch_glyph_string): Remove parameters `row' and `area',
12172 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
12173 and thereabouts. All callers changed.
12174 (get_per_char_metric): Remove parameter `f', unused since
12175 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12177 2011-04-02 Jim Meyering <meyering@redhat.com>
12179 do not dereference NULL upon failed strdup
12180 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12181 (ns_get_family): Likewise.
12183 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12185 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12187 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12189 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12190 later (Bug#8403).
12192 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12194 Add lexical binding.
12196 * window.c (Ftemp_output_buffer_show): New fun.
12197 (Fsave_window_excursion):
12198 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
12200 * lread.c (lisp_file_lexically_bound_p): New function.
12201 (Fload): Bind Qlexical_binding.
12202 (readevalloop): Remove `evalfun' arg.
12203 Bind Qinternal_interpreter_environment.
12204 (Feval_buffer): Bind Qlexical_binding.
12205 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12206 Mark as dynamic.
12207 (syms_of_lread): Declare `lexical-binding'.
12209 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12211 * keyboard.c (eval_dyn): New fun.
12212 (menu_item_eval_property): Use it.
12214 * image.c (parse_image_spec): Use Ffunctionp.
12216 * fns.c (concat, mapcar1): Accept byte-code-functions.
12218 * eval.c (Fsetq): Handle lexical vars.
12219 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12220 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12221 (FletX, Flet): Obey lexical binding.
12222 (Fcommandp): Handle closures.
12223 (Feval): New `lexical' arg.
12224 (eval_sub): New function extracted from Feval. Use it almost
12225 everywhere where Feval was used. Look up vars in lexical env.
12226 Handle closures.
12227 (Ffunctionp): Move from subr.el.
12228 (Ffuncall): Handle closures.
12229 (apply_lambda): Remove `eval_flags'.
12230 (funcall_lambda): Handle closures and new byte-code-functions.
12231 (Fspecial_variable_p): New function.
12232 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12233 but without exporting it to Lisp.
12235 * doc.c (Fdocumentation, store_function_docstring):
12236 * data.c (Finteractive_form): Handle closures.
12238 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12239 interactive spec.
12241 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12242 New byte-codes.
12243 (exec_byte_code): New function extracted from Fbyte_code to handle new
12244 calling convention for byte-code-functions. Add new byte-codes.
12246 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
12248 * alloc.c (Fmake_symbol): Init new `declared_special' field.
12250 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12252 * xdisp.c (redisplay_internal): Fix prototype.
12254 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12256 * xdisp.c (SCROLL_LIMIT): New macro.
12257 (try_scrolling): Use it when setting scroll_limit.
12258 Limit scrolling to 100 screen lines.
12259 (redisplay_window): Even when falling back on "recentering",
12260 position point in the window according to scroll-conservatively,
12261 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12263 (try_scrolling): When point is above the window, allow searching
12264 as far as scroll_max, or one screenful, to compute vertical
12265 distance from PT to the scroll margin position. This prevents
12266 try_scrolling from unnecessarily failing when
12267 scroll-conservatively is set to a value slightly larger than the
12268 window height. Clean up the case of PT below the margin at bottom
12269 of window: scroll_max can no longer be INT_MAX. When aggressive
12270 scrolling is in use, don't let point enter the opposite scroll
12271 margin as result of the scroll.
12272 (syms_of_xdisp) <scroll-conservatively>: Document the
12273 threshold of 100 lines for never-recentering scrolling.
12275 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12277 * dispextern.h (move_it_by_lines):
12278 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
12279 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
12280 (message_log_check_duplicate): Remove parameters `prev_bol' and
12281 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12282 (redisplay_internal): Remove parameter `preserve_echo_area',
12283 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12285 * indent.c (Fvertical_motion):
12286 * window.c (window_scroll_pixel_based, Frecenter):
12287 Don't pass `need_y_p' to `move_it_by_lines'.
12289 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12291 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12292 steal a few bits to be more compact.
12293 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12294 Remove unneeded casts.
12296 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12298 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12300 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12301 binding" message (bug#7967).
12303 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12305 Fix more problems found by GCC 4.6.0's static checks.
12307 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12308 Remove unused local var.
12310 * editfns.c (Fmessage_box): Remove unused local var.
12312 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12313 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12314 Omit unused local vars.
12315 * window.c (shrink_windows): Omit unused local var.
12316 * menu.c (digest_single_submenu): Omit unused local var.
12317 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12318 Omit unused local var.
12320 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12321 Don't assume string length fits in int.
12322 (keyremap_step, read_key_sequence): Use size_t for sizes.
12323 (read_key_sequence): Don't check last_real_key_start redundantly.
12325 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
12326 instead of alloca (Bug#8344).
12328 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12329 (Fbacktrace_frame): Don't assume nframes fits in int.
12331 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
12333 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
12334 concerns.
12336 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12338 * cm.c (calccost): Turn while-do into do-while, for clarity.
12340 * keyboard.c (syms_of_keyboard): Use the same style as later
12341 in this function when indexing through an array. This also
12342 works around GCC bug 48267.
12344 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12346 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12348 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12349 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12351 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12352 This avoids undefined behavior on integer overflow, and is a bit
12353 more convenient anyway since it is compared to a size_t variable.
12355 Variadic C functions now count arguments with size_t, not int.
12356 This avoids an unnecessary limitation on 64-bit machines, which
12357 caused (substring ...) to crash on large vectors (Bug#8344).
12358 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
12359 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

12366 (funcall_lambda, mark_backtrace): Likewise.
12367 * fns.c (concat): Likewise.
12368 * frame.c (x_set_frame_parameters): Likewise.
12369 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12370 0 if not found, not -1. All callers changed.
12372 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12373 (stack_copy_size): Now size_t, not int.
12374 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12376 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12378 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
12379 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12380 All callers changed.
12382 * lisp.h (multibyte_char_to_unibyte):
12383 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
12384 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12385 * character.h (CHAR_TO_BYTE8):
12386 * cmds.c (internal_self_insert):
12387 * editfns.c (general_insert_function):
12388 * keymap.c (push_key_description):
12389 * search.c (Freplace_match):
12390 * xdisp.c (message_dolog, set_message_1): All callers changed.
12392 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12394 * keyboard.c (safe_run_hook_funcall): New function.
12395 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,

12581 Use Frun_hooks.
12582 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

12585 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12587 Fix more problems found by GCC 4.5.2's static checks.
12589 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12590 the first time through the loop, since we know p0 < p1 then.
12591 This also avoids a gcc -Wstrict-overflow warning.
12593 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12594 leading to a memory leak, possible in functions like
12595 load_charset_map_from_file that can allocate an unbounded number
12596 of objects (Bug#8318).
12598 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12599 that could (at least in theory) be that large.
12601 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12602 This is less likely to overflow, and avoids undefined behavior if
12603 overflow does occur. All callers changed. Use strtoul to scan
12604 for the unsigned long integer.
12605 (pint2hrstr): Simplify and tune code slightly.
12606 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

12621 * process.c (Fmake_network_process): Use socklen_t, not int,
12622 where POSIX says socklen_t is required in portable programs.
12623 This fixes a porting bug on hosts like 64-bit HP-UX, where
12624 socklen_t is wider than int (Bug#8277).
12625 (Fmake_network_process, server_accept_connection):
12626 (wait_reading_process_output, read_process_output):
12627 Likewise.

12639 Make tparam.h and terminfo.c consistent.
12640 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12641 Include tparam.h instead, since it declares them.
12642 * cm.h (PC): Remove extern decl; tparam.h now does this.
12643 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12644 * terminfo.c: Include tparam.h, to check interfaces.
12645 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12646 (tparam): Adjust signature to match interface in tparam.h;
12647 this removes some undefined behavior. Check that outstring and len
12648 are zero, which they always are with Emacs.
12649 * tparam.h (PC, BC, UP): New extern decls.
12651 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12652 (xftfont_open): Rename locals to avoid shadowing.

12669 (find_automatic_composition, composition_adjust_point): Likewise.
12670 (composition_update_it): Mark var as initialized.

12678 (BUF_DEC_POS): Be more systematic about renaming local temporaries
12679 to avoid shadowing.

12691 Fix pointer signedness.
12692 (alsa_choose_format): Remove unused local var.
12693 (wav_play): Initialize a variable to 0, to prevent undefined
12694 behavior (Bug#8278).
12696 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
12698 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
12700 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
12701 clobbering (Bug#8298).
12702 * sysdep.c (sys_subshell): Likewise.
12703 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12705 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
12706 This should get cleaned up, so that child_setup has the
12707 same signature on all platforms.
12709 * callproc.c (call_process_cleanup): Now static.
12710 (relocate_fd): Rename locals to avoid shadowing.
12712 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
12714 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
12715 not to be necessary, and produces flickering.
12717 2011-03-20 Glenn Morris <rgm@gnu.org>
12719 * config.in: Remove file.
12721 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

12766 Define only if needed.
12768 * unexelf.c (unexec): Name an expression,
12769 to avoid gcc -Wbad-function-cast warning.
12770 Use a different way to cause a compilation error if anyone uses
12771 n rather than nn, a way that does not involve shadowing.
12772 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
12774 * deps.mk (unexalpha.o): Remove; unused.

12842 (Fformat_time_string, Fencode_time, Finsert_char):
12843 (Ftranslate_region_internal, Fformat):
12844 Rename or remove local vars to avoid shadowing.
12845 (Ftranslate_region_internal): Mark var as initialized.
12847 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
12848 avoid shadowing.
12850 * lisp.h (eassert): Check that the argument compiles, even if
12851 ENABLE_CHECKING is not defined.
12853 * data.c (Findirect_variable): Name an expression, to avoid
12854 gcc -Wbad-function-cast warning.
12855 (default_value, arithcompare, arith_driver, arith_error): Now static.
12856 (store_symval_forwarding): Rename local to avoid shadowing.
12857 (Fmake_variable_buffer_local, Fmake_local_variable):
12858 Mark variables as initialized.
12859 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
12861 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
12862 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
12863 Rename locals to avoid shadowing.
12864 (mark_stack): Move local variables into the #ifdef region where
12865 they're used.
12866 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
12867 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
12868 needed otherwise.
12869 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
12870 (GC_STRING_CHARS): Remove; not used.
12871 (Fmemory_limit): Cast sbrk's returned value to char *.
12873 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
12874 avoids undefined behavior in theory.
12876 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
12878 Use functions, not macros, for up- and down-casing (Bug#8254).
12879 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12880 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
12881 to use the following functions instead of these macros.
12882 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
12883 EMACS_INT, since callers assume the returned value fits in int.
12884 (upcase1): Likewise, for UPCASE_TABLE.
12885 (uppercasep, lowercasep, upcase): New static inline functions.
12886 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
12887 the race-condition problem in the old DOWNCASE.
12889 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
12890 Rename locals to avoid shadowing.
12891 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
12892 (regex_compile, re_search_2, re_match_2_internal):
12893 Remove unused local vars.
12894 (FREE_VAR): Rewrite so as not to use empty "else",
12895 which gcc can warn about.
12896 (regex_compile, re_match_2_internal): Mark locals as initialized.
12897 (RETALLOC_IF): Define only if needed.
12898 (WORDCHAR_P): Likewise. This one is never needed, but is used
12899 only in a comment talking about a compiler bug, so put inside
12900 the #if 0 of that comment.
12901 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
12902 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
12903 Remove; unused.
12905 * search.c (boyer_moore): Rename locals to avoid shadowing.

12907 (PREV_CHAR_BOUNDARY): Likewise.
12909 * search.c (simple_search): Remove unused var.
12911 * dired.c (compile_pattern): Move decl from here ...
12912 * lisp.h: ... to here, so that it can be checked.
12913 (struct re_registers): New forward decl.
12915 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
12917 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
12918 All uses changed.
12919 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
12920 Rename locals to avoid shadowing.
12921 (Fvertical_motion): Mark locals as initialized.
12923 * casefiddle.c (casify_object, casify_region): Now static.
12924 (casify_region): Mark local as initialized.
12926 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
12928 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
12929 New macros, so that the caller can use some names other than
12930 gcpro1, gcpro2, etc.
12931 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
12932 of the new macros.
12933 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
12934 argument, for consistency with GCPRO2_VAR, etc: it is now the
12935 prefix of the variable, not the variable itself. All uses
12936 changed.
12937 * dired.c (directory_files_internal, file_name_completion):
12938 Rename locals to avoid shadowing.
12940 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
12941 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
12942 dired.c's scmp function, had undefined behavior.
12943 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12944 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
12945 * buffer.h: ... to here, because these macros use current_buffer,
12946 and the new implementation with inline functions needs to have
12947 current_buffer in scope now, rather than later when the macros
12948 are used.
12949 (downcase, upcase1): New static inline functions.
12950 (DOWNCASE, UPCASE1): Reimplement using these functions.
12951 This avoids undefined behavior in expressions like
12952 DOWNCASE (x) == DOWNCASE (y), which previously suffered
12953 from race conditions in accessing the global variables
12954 case_temp1 and case_temp2.
12955 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
12956 * lisp.h (case_temp1, case_temp2): Remove their decls.
12957 * character.h (ASCII_CHAR_P): Move from here ...
12958 * lisp.h: ... to here, so that the inline functions mentioned
12959 above can use them.
12961 * dired.c (directory_files_internal_unwind): Now static.
12963 * fileio.c (file_name_as_directory, directory_file_name):
12964 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
12965 Now static.
12966 (file_name_as_directory): Use const pointers when appropriate.
12967 (Fexpand_file_name): Likewise. In particular, newdir might
12968 point at constant storage, so make it a const pointer.
12969 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
12970 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
12971 signedness issues.
12972 (Fset_file_times, Finsert_file_contents, auto_save_error):
12973 Rename locals to avoid shadowing.
12975 * minibuf.c (choose_minibuf_frame_1): Now static.
12976 (Ftry_completion, Fall_completions): Rename or remove locals
12977 to avoid shadowing.
12979 * marker.c (bytepos_to_charpos): Remove; unused.
12981 * lisp.h (verify_bytepos, count_markers): New decls,
12982 so that gcc does not warn that these functions aren't declared.
12984 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
12985 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
12986 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
12987 (copy_text): Remove unused local var.
12989 * filelock.c (within_one_second): Now static.
12990 (lock_file_1): Rename local to avoid shadowing.
12992 * buffer.c (fix_overlays_before): Mark locals as initialized.
12993 (fix_start_end_in_overlays): Likewise. This function should be
12994 simplified by using pointers-to-pointers, but that's a different
12995 matter.
12996 (switch_to_buffer_1): Now static.
12997 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
12998 (report_overlay_modification): Rename locals to avoid shadowing.
13000 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13001 Fix pointer signedness issue.
13002 (sys_subshell): Mark local as volatile if checking for lint,
13003 to suppress a gcc -Wclobbered warning that does not seem to be right.
13004 (MAXPATHLEN): Define only if needed.
13006 * process.c (serial_open, serial_configure): Move decls from here ...
13007 * systty.h: ... to here, so that they can be checked.
13009 * fns.c (get_random, seed_random): Move extern decls from here ...
13010 * lisp.h: ... to here, so that they can be checked.
13012 * sysdep.c (reset_io): Now static.
13013 (wait_for_termination_signal): Remove; unused.
13015 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
13016 (copy_keymap_item, append_key, push_text_char_description):
13017 Now static.
13018 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13019 (DENSE_TABLE_SIZE): Remove; unused.
13020 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13021 (describe_map_tree):
13022 Rename locals to avoid shadowing.
13024 * keyboard.c: Declare functions static if they are not used elsewhere.
13025 (echo_char, echo_dash, cmd_error, top_level_2):
13026 (poll_for_input, handle_async_input): Now static.

13041 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
13042 (DEFINE_DUMMY_FUNCTION): New macro.
13043 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
13044 Use it.
13045 (main): Add casts to avoid warnings
13046 if GCC considers string literals to be constants.
13048 * lisp.h (fatal_error_signal): Add decl, since it's exported.

13051 (xd_signature, xd_append_arg, xd_initialize):
13052 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13053 (Fdbus_method_return_internal, Fdbus_method_error_internal):

13171 For example, without this patch (encode-time 0 0 0 1 1
13172 1152921504606846976) returns the obviously-bogus value (-948597
13173 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
