3 * lread.c (load_path_check): New function, split from init_lread.
4 (init_lread): Reorganize. Motivation:
5 If EMACSLOADPATH is set, check/warn about that rather than the
6 defaults, which we are not going to use. Hence we can remove
7 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8 Don't warn if site-lisp directories are missing.
9 If not installed, start from a blank load-path, since
10 PATH_LOADSEARCH refers to the eventual installation directories.

14 Support truncation and continuation glyphs on GUI frames, when
15 fringes are disabled. (Bug#11832)
16 * xdisp.c (init_iterator): Get dimensions of truncation and
17 continuation glyphs even if on GUI frames. Adjust
18 it->last_visible_x on GUI frames when the left or right fringes,
20 (start_display, move_it_in_display_line_to): Handle the case of a
21 GUI frame without a fringe to display continuation or truncation
23 (insert_left_trunc_glyphs): Support GUI frames: make sure
24 truncation glyphs overwrite enough glyphs from the current line to
25 have sufficient space in pixels.
26 (display_line): Support truncation and continuation glyphs on GUI
27 frames. If some spare pixels are left on the line after inserting
28 the truncation glyphs, fill that space with a stretch glyph of a
29 suitably computed width.
31 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
32 produce_glyphs, to support GUI sessions.
34 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
36 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
38 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
40 Do not require float-time's arg to fit in time_t (Bug#11825).
41 This works better on hosts where time_t is unsigned, and where
42 float-time is applied to the (negative) difference between two times.
43 * editfns.c (decode_time_components): Last arg is now double *,
44 not int *, and means to store all the result as a double, without
45 worrying about whether the seconds part fits in time_t.
47 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
49 (Ffloat_time): Do not fail merely because the specified time falls
50 outside of time_t range.
52 2012-07-07 Glenn Morris <rgm@gnu.org>
54 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

71 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
72 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
74 * xfont.c (compare_font_names): Redo to omit the need for casts.

82 X Windows version. Doc fix.
83 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
85 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
86 Eli Zaretskii <eliz@gnu.org>
88 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
89 Windows-specific code from nt/config.nt moved here.
90 Obsolete settings removed.
92 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
94 * process.c: Avoid unnecessary calls to gettime.
95 (wait_reading_process_output): Don't get the time of day
96 when gobbling data immediately and not waiting, as there's no need
97 for it in that case. This removes a FIXME.
99 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
101 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
102 is defined (Bug#11768).
104 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

110 byte_char_debug_check with correct arguments.
112 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

115 * marker.c (byte_char_debug_check, count_markers): Use
116 only if ENABLE_CHECKING is defined.
117 (byte_debug_flag): Remove.
118 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
119 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
121 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
123 Avoid code repetition in marker-related functions.
124 * marker.c (attach_marker): New function.
125 (Fset_marker, set_marker_restricted, set_marker_both)
126 (set_marker_restricted_both): Use it.
127 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
128 Consistently rename charno to charpos.
129 (marker_position): Add eassert.
130 (marker_byte_position): Convert to eassert.
132 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
134 Simplify list operations in unchain_overlay and unchain_marker.

149 * window.c (save_window_save): Likewise.
151 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
153 Do not use Fdelete_overlay in delete_all_overlays
154 to avoid redundant calls to unchain_overlay.
155 * buffer.c (drop_overlay): New function.
156 (delete_all_overlays, Fdelete_overlay): Use it.
157 * minibuf.c (get_minibuffer): Fix comment.
159 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
161 Port to OpenBSD 5.1 amd64.
162 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
163 This is needed for OpenBSD, and should be harmless on all BSD systems.
164 Also, include <sys/sysctl.h>, as it should be available on all
165 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
166 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
167 use p_pid member, not kp_proc.pid.
169 2012-07-06 Glenn Morris <rgm@gnu.org>
171 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
173 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
175 More xmalloc and related cleanup.
176 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

180 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
181 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
182 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
183 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
184 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
186 Omit needless casts involving void * pointers and allocation.
187 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
188 as the former is more robust if P's type is changed.
189 Prefer xzalloc to xmalloc + memset 0.
190 Simplify malloc-or-realloc to realloc.
191 Don't worry about xmalloc returning a null pointer.
192 Prefer xstrdup to xmalloc + strcpy.
193 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
195 * keyboard.c (apply_modifiers_uncached): Prefer local array to
196 alloca of a constant.
198 2012-07-05 Eli Zaretskii <eliz@gnu.org>
200 * xdisp.c (display_line): Fix horizontal pixel coordinates when
201 hscroll is larger than the line width. Fixes long and futile
202 looping inside extend_face_to_end_of_line (on a TTY) producing
203 glyphs that are not needed and thrown away.
205 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
207 * marker.c (set_marker_restricted_both): Simplify by using
210 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
212 * editfns.c (region_limit): Simplify by using clip_to_bounds.
214 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

234 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
235 coordinates when window's hscroll is set to insanely large
238 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
240 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

307 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
308 This should be fixed in a better way; see Eli Zaretskii in
309 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
310 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
312 * fileio.c (time_error_value): Rename from special_mtime.
313 The old name's problems were noted by Eli Zaretskii in
314 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
316 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
317 This variable's comment says Emacs needs at least one GDB-visible
318 symbol of type enum pvec_type, to work around GDB problems.
319 The symbol's value doesn't matter.
321 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
322 that causes compilation to fail on pre-C99 compilers.
324 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
326 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

332 headers for buffer_defaults and buffer_local_symbols.
333 Reported by Juanma Barranquero <lekktu@gmail.com>.
335 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
337 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
338 * lisp.h (enum pvec_type): Use fewer bits.
339 (PSEUDOVECTOR_SIZE_BITS): New constant.
340 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
341 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
343 (PSEUDOVECTOR_TYPEP): New macro.
344 (TYPED_PSEUDOVECTORP): Use it.

349 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
350 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
351 (sweep_vectors): Use it. Use local var `total_bytes' instead of
352 abusing vector->header.next.nbytes.
353 (live_vector_p): Use PVEC_TYPE.
354 (mark_object): Adapt code to extract pvectype. Use switch.
356 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>

366 to avoid compiler warning. Add eassert.
367 * search.c (simple_search): Initialize match_byte to avoid
368 compiler warning. Add eassert.
370 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
372 Avoid weird behavior with large horizontal scrolls.
373 Without this change, for example, large hscroll values would
374 mess up Emacs's display on Fedora 15 x86, presumably due to
375 overflows in int calculations in the display code.
376 Also, if buffers had long lines, Emacs would freeze.
377 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
378 (set_window_hscroll): New function, containing the old guts of
379 Fset_window_hscroll. Return the clipped value.
380 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
381 This avoids the need to check against PTRDIFF_MAX.
383 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
385 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

391 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
392 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
393 since GCC 4.4.6 issues a bogus warning for them.
395 Fix bugs in file timestamp newness comparisons.
396 * fileio.c (Ffile_newer_than_file_p):
397 * lread.c (Fload): Use full timestamp resolution of files,
398 not just the 1-second resolution, so that files that are only
399 slightly newer still count as newer.
400 * fileio.c (Ffile_newer_than_file_p): Don't assume file
401 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
403 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
405 * fileio.c: Improve handling of file time marker. (Bug#11852)
406 (special_mtime): New function.
407 (Finsert_file_contents, Fverify_visited_file_modtime):

413 marker for non-existing file. (Bug#11852)
415 2012-07-03 Glenn Morris <rgm@gnu.org>
417 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
418 and did not make it into globals.h).
420 2012-07-03 Tom Tromey <tromey@redhat.com>

462 buffer for invisible buffers. (Bug#1229)
464 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
466 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
467 values which aren't power of 2.
468 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
469 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users

480 * alloc.c (allocate_vector_block): Remove redundant
481 calls to mallopt if DOUG_LEA_MALLOC is defined.
482 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
483 avoid calls to mallopt if zero_vector is returned.
485 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
487 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
488 is enabled, avoid dereferencing NULL current_sblock if
491 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
493 Cleanup basic buffer management.
494 * buffer.h (struct buffer): Change layout to use generic vector
495 marking code. Fix some comments. Change type of 'clip_changed'
496 to bitfield. Remove unused #ifndef old.
497 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
498 (GET_OVERLAYS_AT): Fix indentation.
499 (for_each_per_buffer_object_at): New macro.

503 * alloc.c (allocate_buffer): Adjust to match new layout of
504 struct buffer. Fix comment.
505 (mark_overlay): New function.
506 (mark_buffer): Use it. Use mark_vectorlike to mark normal
507 Lisp area of struct buffer.
508 (mark_object): Use it. Adjust marking of misc objects
509 and related comments.
511 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
513 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
514 wrapper that is not needed because the wrapped code is a no-op (zero
515 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
516 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
518 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
520 * alloc.c (mark_buffer): Simplify. Remove prototype.
521 (mark_object): Add comment. Reorganize marking of vector-like
522 objects. Use CHECK_LIVE for all vector-like objects except buffers
523 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
524 redundant calls to mark_vectorlike for bool vectors.
526 2012-06-30 Glenn Morris <rgm@gnu.org>
528 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
530 * epaths.in (PATH_SITELOADSEARCH): New.
531 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
532 This is rather than relying on --enable-locallisppath elements
533 having "site-lisp" in their names. (Bug#10208#25, 11658)
535 2012-06-30 Eli Zaretskii <eliz@gnu.org>
537 * w32proc.c (sys_select): Accept and ignore one more argument.
539 * w32.c (emacs_gnutls_pull): Call select with one more argument.
541 * sysselect.h [DOS_NT]: Don't include sys/select.h.
542 (pselect) [!MS_DOS]: Redirect to sys_select.
544 * sysdep.c: Don't include dos.h and dosfns.h.
546 * process.c (sys_select):
547 * msdos.c (sys_select): Accept one more argument and ignore it.
549 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
550 adapt data types and code to that.
553 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
554 which clashes with the gnulib function of the same name.
556 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
558 * font.c (font_style_to_value, font_style_symbolic)
559 (font_prop_validate_style): Add type checks for values in
562 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
564 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
567 2012-06-29 Eli Zaretskii <eliz@gnu.org>
569 * xdisp.c (try_window_id): Undo last change.
571 * w32.c (getwd): Adjust commentary about startup_dir.
572 (init_environment): Always call sys_access, even in non-MSVC
573 builds. Don't chdir to the directory of the Emacs executable.
574 This undoes code from 1997 which was justified by the need to
575 "avoid conflicts when removing and renaming directories". But its
576 downside was that every relative file name was being interpreted
577 relative to the directory of the Emacs executable, which can never
578 be TRT. In particular, it broke sys_access when called with
580 (sys_access): Map GetLastError to errno.
582 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
584 * window.h (struct window): Change type of 'fringes_outside_margins'
585 to bitfield. Fix comment. Adjust users accordingly.
586 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
588 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
591 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
593 * gnutls.c (emacs_gnutls_handshake):
594 Add QUIT to make the loop interruptible.
596 2012-06-29 Glenn Morris <rgm@gnu.org>
598 * charset.c (init_charset): Make lack of etc/charsets fatal.
600 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
602 * editfns.c (region_limit): Fix type mismatch.
604 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

607 undefined. Convert from xassert to eassert.
608 * nsmenu.m: Convert from xassert to eassert.
609 * nsterm.m: Likewise.
611 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
613 * editfns.c (region_limit): Clip to narrowing (bug#11770).
615 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
617 Avoid integer overflow on scroll-left and scroll-right.
618 * window.c (HSCROLL_MAX): New macro.
619 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
620 overflow when requested scroll falls outside ptrdiff_t range.
622 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
624 * window.h (struct window): Change type of 'hscroll',
625 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
626 'last_modified' and 'last_overlay_modified' to EMACS_INT.
627 Adjust users accordingly.
628 * xdisp.c (try_cursor_movement): Replace type check with eassert.
629 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
630 from EMACS_INT to ptrdiff_t.
631 (make_window): Omit redundant initialization.
633 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
635 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
637 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
639 * window.h (struct window): Change type of 'use_time' and
640 'sequence_number' from Lisp_Object to int.
641 * frame.c (make_frame): Adjust users accordingly.
642 * print.c (print_object): Likewise.
643 * window.c (select_window, Fwindow_use_time, make_parent_window)

668 Convert from xassert to eassert.
669 * alloc.c: Convert from xassert to eassert.
671 * dispnew.c: Likewise.
673 * fringe.c: Likewise.
674 * ftfont.c: Likewise.

707 * alloc.c (make_uninit_multibyte_string): Initialize intervals
708 as in make_pure_string and make_pure_c_string.

712 * alloc.c (allocate_string): Fix last change.
714 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
716 * alloc.c (allocate_string): Remove two redundant calls
717 to memset, add explicit initialization where appropriate.
719 2012-06-27 Glenn Morris <rgm@gnu.org>
721 * lisp.mk (lisp): Remove paths.elc.
723 2012-06-27 Chong Yidong <cyd@gnu.org>
725 * doc.c (Fsubstitute_command_keys): Fix punctuation.
727 2012-06-26 John Wiegley <johnw@newartisans.com>
729 * unexmacosx.c (copy_data_segment): Add two section names used
730 on Mac OS X Lion: __mod_init_func and __mod_term_func.
732 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
733 when building with Clang.
735 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>
737 * eval.c (Fapply): Allow calling it with a single argument.

762 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
764 * alloc.c: Remove build_string.
765 * lisp.h: Define build_string as static inline. This provides
766 a better opportunity to optimize away calls to strlen when the
767 function is called with compile-time constant argument.
768 * image.c (imagemagick_error): Convert to build_string.
769 * w32proc.c (sys_spawnve): Likewise.
770 * xterm.c (x_term_init): Likewise.
772 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
774 Use sprintf return value instead of invoking strlen on result.
775 In the old days this wasn't portable, since some sprintf
776 implementations returned char *. But they died out years ago and
777 Emacs already assumes sprintf returns int.
778 Similarly for float_to_string.
779 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
780 * ccl.c (ccl_driver):
781 * character.c (string_escape_byte8):

784 * print.c (print_object):
785 * xdisp.c (message_dolog):
786 * xfns.c (syms_of_xfns):
787 Use sprintf or float_to_string result to avoid need to call strlen.
788 * data.c (Fnumber_to_string):
789 Use make_unibyte_string, since the string must be ASCII.
790 * lisp.h, print.c (float_to_string): Now returns int length.
791 * term.c (produce_glyphless_glyph):
792 Use sprintf result rather than recomputing it.
794 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
795 * Makefile.in (ALL_CFLAGS):
796 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
797 * gmalloc.c, regex.c: Include <config.h> unconditionally.

818 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
820 * gtkutil.c (get_utf8_string): Remove redundant assignment.
821 sprintf already null-terminates its output.
823 * xfns.c (x_window): Remove redundant cast.
825 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
827 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
828 `const char *' to `char *' to avoid compiler warning.
830 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
832 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
833 instead of truncating it to 63 (admittedly a generous limit).
835 * process.c: Fix spelling and caps in comments.
837 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
839 * emacs.c (setpgrp): Remove definition, unused.

888 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
890 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
891 * lisp.h (WAIT_READING_MAX): New macro.
892 * dispnew.c (Fsleep_for, sit_for):
893 * keyboard.c (kbd_buffer_get_event):
894 * process.c (Faccept_process_output):
895 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
896 This improves on the previous patch, which introduced a bug
897 when time_t is unsigned and as wide as intmax_t.
898 See <http://bugs.gnu.org/9000#51>.
900 2012-06-23 Eli Zaretskii <eliz@gnu.org>
902 * dispnew.c (sit_for, Fsleep_for):
903 * keyboard.c (kbd_buffer_get_event):

916 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
917 Privately reported by Herbert J. Skuhra.
918 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
920 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
921 not make_lisp_timeval, when the argument is of type EMACS_TIME.
923 2012-06-23 Eli Zaretskii <eliz@gnu.org>
925 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
926 last argument of make_unibyte_string.
928 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
929 language ID in the event parameters.
931 * w32term.c (w32_read_socket): Put the new keyboard codepage into
932 event.code, not the obscure "character set ID".
934 2012-06-23 Chong Yidong <cyd@gnu.org>
936 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
938 2012-06-23 Eli Zaretskii <eliz@gnu.org>
940 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

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

963 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
965 Support higher-resolution time stamps (Bug#9000).
966 The time stamps are only nanosecond-resolution at the C level,
967 since that's the best that any real-world system supports now.
968 But they are picosecond-resolution at the Lisp level, as that's
969 easy, and leaves room for future OS improvements.
971 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
974 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
975 Don't get current time unless it's needed.
977 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
978 now provides it if it's absent.
979 (start_atimer): Port to higher-res time stamps.
980 Check for time stamp overflow. Don't get current time more
981 often than is needed.
983 * buffer.h (struct buffer): Buffer modtime now has high resolution.
984 Include systime.h, not time.h.
985 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

988 (Ffile-attributes): File times now have higher resolution.
990 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
991 (struct image): Timestamp now has higher resolution.
993 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
994 has at least microseconds now. All uses removed.
995 (update_frame, update_single_window, update_window, update_frame_1)
996 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
998 * editfns.c (time_overflow): Now extern.
999 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
1000 (float-time, Fformat_time_string, Fcurrent_time_string)
1001 (Fcurrent_time_zone): Accept and generate higher-resolution
1003 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
1004 (decode_time_components, lisp_seconds_argument): New functions.
1005 (make_time): Now static.
1006 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1007 Report an error if the time is invalid, rather than having the caller
1010 * fileio.c: Include <stat-time.h>
1011 (Fcopy_file): Copy higher-resolution time stamps.
1012 Prefer to set the time stamp via a file descriptor if that works.
1013 (Fset_file_times, Finsert_file_contents, Fwrite_region)
1014 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
1015 (Fvisited_file_modtime, Fset_visited_file_modtime):
1016 Support higher-resolution time stamps.
1018 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
1020 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
1022 * image.c (prepare_image_for_display, clear_image_cache)
1023 (lookup_image): Port to higer-resolution time stamps.
1025 * keyboard.c (start_polling, bind_polling_period):
1026 Check for time stamp overflow.
1027 (read_char, kbd_buffer_get_event, timer_start_idle)
1028 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
1029 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1030 Port to higher-resolution time stamps. Do not assume time_t is signed.
1031 (decode_timer): New function. Timers are now vectors of length 9,
1032 not 8, to accommodate the picosecond component.
1033 (timer_check_2): Use it.
1035 * nsterm.m (select_timeout, timeval_subtract): Remove.
1036 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1037 as they're a bit more accurate and handle overflow better.
1038 (ns_select): Change prototype to be compatible with pselect.
1039 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1040 * nsterm.h (ns_select): Adjust prototype.
1042 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
1043 us-resolution time stamps.
1044 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1046 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1048 * lisp.h (time_overflow): New decl.
1049 (wait_reading_process_output): First arg is now intmax_t, not int,
1050 to accommodate larger waits.
1052 * process.h (struct Lisp_Process.read_output_delay):
1053 Now counts nanoseconds, not microseconds.
1054 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
1056 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
1057 (wait_reading_process_output):
1058 Port to ns-resolution time stamps.
1059 (Faccept_process_output, wait_reading_process_output):
1060 Check for time stamp overflow. Do not assume time_t is signed.
1061 (select_wrapper): Remove; we now use pselect.
1062 (Fprocess_attributes): Now generates ns-resolution time stamps.
1064 * sysdep.c: Include utimens.h. Don't include utime.h
1065 or worry about struct utimbuf; gnulib does that for us now.
1066 (gettimeofday): Remove; gnulib provides a substitute.
1067 (make_timeval): New function.
1068 (set_file_times): Now sets ns-resolution time stamps.
1069 New arg FD; all uses changed.
1070 (time_from_jiffies, ltime_from_jiffies, get_up_time)
1071 (system_process_attributes):
1072 Now returns ns-resolution time stamp. All uses changed.
1073 Check for time stamp overflow.
1075 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1076 provides a substitute now.
1078 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1079 since it guarantees struct timespec.
1080 (EMACS_TIME): Now struct timespec, so that we can support
1081 ns-resolution time stamps.
1082 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
1083 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
1084 (EMACS_USECS): Remove.
1085 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
1086 so multiply the arg by 1000 before storing it.
1087 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
1089 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

1094 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
1095 (set_file_times, make_time, lisp_time_argument): Adjust signature.
1096 (make_timeval, make_lisp_time, decode_time_components): New decls.
1097 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
1098 that it mishandled time_t overflow. You can't compare by subtracting!
1099 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
1100 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
1102 * term.c: Include <sys/time.h>.
1103 (timeval_to_Time): New function, for proper overflow wraparound.
1104 (term_mouse_position, term_mouse_click): Use it.
1106 * undo.c (record_first_change): Support higher-resolution time stamps
1108 (Fprimitive_undo): Use them when restoring time stamps.
1110 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
1111 (w32_get_internal_run_time):
1112 Port to higher-resolution Emacs time stamps.
1113 (ltime): Now accepts single 64-bit integer, as that's more convenient
1116 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
1118 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
1119 for compatibility with pselect. Support ns-resolution time stamps.
1121 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
1123 * xselect.c (wait_for_property_change, x_get_foreign_selection):
1124 Check for time stamp overflow, and support ns-resolution time stamps.
1126 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
1127 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
1128 (timeval_subtract): Remove; no longer needed.
1129 (XTflash, XTring_bell, x_wait_for_event):
1130 Port to ns-resolution time stamps. Don't assume time_t is signed.

1136 2012-06-22 Eli Zaretskii <eliz@gnu.org>
1138 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
1139 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
1140 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
1141 staticidx goes up to 1597 out of 1600 = 0x640.)
1143 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
1145 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
1146 Otherwise, the umask might be mistakenly 0 while handling input signals.
1148 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
1150 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

1156 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
1157 access to `contents' member of Lisp_Vector objects with AREF and ASET
1160 2012-06-19 Chong Yidong <cyd@gnu.org>
1162 * frame.c (delete_frame): When selecting a frame on a different
1163 text terminal, do not alter the terminal's top-frame.

1167 (unwind_format_mode_line): Restore them.
1168 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
1170 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
1171 since tty frames can be explicitly named.
1172 (prepare_menu_bars): Likewise.
1174 * term.c (Ftty_top_frame): New function.
1176 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1178 Port byte-code-meter to modern targets.
1179 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
1180 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
1181 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
1182 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
1183 (METER_1, METER_2): Simplify.
1185 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

1189 2012-06-18 Martin Rudalics <rudalics@gmx.at>
1191 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
1192 gets killed during executing of this function (Bug#11665).
1193 Try to always return Qt when the buffer has been actually killed.
1194 (Vkill_buffer_query_functions): In doc-string say that functions
1195 run by this hook should not change the current buffer.
1197 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
1199 Fix recently-introduced process.c problems found by static checking.
1200 * process.c (write_queue_push, write_queue_pop, send_process):

1219 * lisp.h (eassert): Assume C89 or later.
1220 This removes the need for CHECK.
1221 (CHECK): Remove. Its comments about always evaluating its
1222 argument were confusing, as 'eassert' typically does not evaluate
1225 * coding.c (produce_chars): Use ptrdiff_t, not int.
1227 * xterm.c (x_draw_underwave): Check for integer overflow.
1228 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

1503 * xdisp.c (vmessage): Treat frame message as multibyte.
1504 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
1505 would generate the diagnostic "Making \302\247 buffer-local while

1523 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
1524 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
1526 2012-06-08 Eli Zaretskii <eliz@gnu.org>
1528 * alloc.c (allocate_vectorlike): Fix last change.
1530 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
1532 Block-based vector allocation of small vectors.
1533 * lisp.h (struct vectorlike_header): New field `nbytes',
1534 adjust comment accordingly.
1535 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
1536 to denote vector blocks. Adjust users (live_vector_p,
1537 mark_maybe_pointer, valid_lisp_object_p) accordingly.
1538 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
1539 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
1540 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
1541 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
1542 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

1557 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
1559 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
1561 * doprnt.c (doprnt): Truncate multibyte char correctly.
1562 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
1563 would mishandle a string argument "Xc" if X was a multibyte
1564 character of length 2: it would truncate after X's first byte
1565 rather than including all of X.
1567 2012-06-06 Chong Yidong <cyd@gnu.org>
1569 * buffer.c (word_wrap): Doc fix.
1571 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

1597 position is past the end of the mode line string.
1599 * buffer.c (buffer_local_value_1): New function, split from
1600 Fbuffer_local_value; can return Qunbound.

1618 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
1619 Convert pctcpu and pctmem to Lisp float properly.
1620 Let the compiler fold better, as 100.0/0x8000 is exact.
1622 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
1624 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
1627 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
1629 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
1631 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
1633 For a 'struct window', replace some Lisp_Object fields to
1634 bitfields where appropriate, remove unused fields.
1635 * window.h (struct window): Remove unused 'last_mark_x' and
1636 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
1637 change it's type from Lisp_Object to bitfield.
1638 Change type of 'force_start', 'optional_new_start',
1639 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
1640 fields from Lisp_Object to bitfield. Adjust users accordingly.
1642 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
1644 Pacify gcc -Wdouble-precision when using Xaw.
1645 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
1646 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
1647 Use 'float' consistently, rather than 'float' in most places
1648 and 'double' in a couple of places.
1650 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1652 * xdisp.c (handle_stop): Detect whether we have overlay strings
1653 loaded by testing it->current.overlay_string_index to be
1654 non-negative, instead of checking whether n_overlay_strings is
1655 positive. (Bug#11587)
1657 2012-05-31 Chong Yidong <cyd@gnu.org>
1659 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
1661 * doc.c (Fsubstitute_command_keys): Doc fix.
1663 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1665 * search.c (search_buffer): Remove calls to
1666 r_alloc_inhibit_buffer_relocation, as it is now called by
1667 maybe_unify_char, which was the cause of relocation of buffer text
1670 2012-05-31 Eli Zaretskii <eliz@gnu.org>
1672 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
1673 for the duration of call to load_charset, to avoid problems with
1674 callers of maybe_unify_char that access buffer text through C
1677 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
1678 decrement the inhibition flag, instead of just setting or
1681 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
1683 Remove obsolete '#define static' cruft.
1684 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
1685 This #undef was "temporary" in 2000; it is no longer needed
1686 now that '#define static' has gone away.
1687 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
1688 (gray_bitmap_bits): Remove; no longer needed.
1689 All uses replaced with definiens.
1690 * xterm.c: Include "bitmaps/gray.xbm".
1692 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
1694 Clean up __executable_start, monstartup when --enable-profiling.
1695 The following changes affect the code only when profiling.
1696 * dispnew.c (__executable_start): Rename from safe_bcopy.
1697 Define only on platforms that need it.
1698 * emacs.c: Include <sys/gmon.h> when profiling.
1699 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
1700 (__executable_start): Remove decl, since lisp.h does it now.
1701 (safe_bcopy): Remove decl; no longer has that name.
1702 (main): Coalesce #if into single bit of code, for simplicity.
1703 Cast pointers to uintptr_t, since standard libraries want integers

1728 * lread.c (read1): Tiny simplification.
1730 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
1732 Do not create empty overlays with the evaporate property (Bug#9642).
1733 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
1734 Bug#9642, but explicitly check that the buffer the overlay would
1735 be moved to is live and rearrange lines to make sure that errors
1736 will not put the overlay in an inconsistent state.
1737 (Fdelete_overlay): Cosmetics.
1739 2012-05-28 Eli Zaretskii <eliz@gnu.org>
1741 * w32term.c (my_bring_window_to_top): New function.
1742 (x_raise_frame): Use handle returned by DeferWindowPos, which
1743 could be different from the original one.

1747 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
1748 by calling BringWindowToTop.
1750 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
1751 (WM_EMACS_END): Increase by one.
1753 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
1755 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
1756 This avoids undefined behavior that might cause the eassert
1757 to not catch an out-of-range value.
1759 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
1761 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

1771 when referring to sectname field in printf format.
1773 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
1775 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
1776 Only r_alloc_inhibit_buffer_relocation needed to be added;
1777 the others were already declared.
1779 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
1780 before checking whether it's out of range. Put the check inside
1782 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
1784 2012-05-27 Ken Brown <kbrown@cornell.edu>
1786 * callproc.c (Fcall_process): Restore a line that was accidentally
1787 commented out in the 2011-02-13 change (bug#11547).

1791 * lisp.h [REL_ALLOC]: Add prototypes for external functions
1792 defined on ralloc.c.
1794 * buffer.c [REL_ALLOC]: Remove prototypes of
1795 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
1796 they are now on lisp.h.
1798 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
1800 * search.c (search_buffer): Use it to inhibit relocation of buffer
1801 text while re_search_2 is doing its job, because re_search_2 is
1802 passed C pointers to buffer text. (Bug#11519)
1804 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
1807 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
1808 state after an additional call to move_it_in_display_line_to, keep
1809 the values of it->max_ascent and it->max_descent found for the
1811 (pos_visible_p): Revert the comparison against bottom_y to what it
1812 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
1815 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
1817 Fix coding-related core dumps with gcc -ftrapv.
1818 The code was computing A - B, where A and B are pointers, and B is
1819 random garbage. This can lead to core dumps on platforms that
1820 have special pointer registers, and it also leads to core dumps on
1821 x86-64 when compiled with gcc -ftrapv. The fix is to compute
1822 A - B only when B is initialized properly.
1823 * coding.c (coding_set_source, coding_set_destination): Return void.
1824 (coding_change_source, coding_change_destinations): New functions,
1825 with the old behaviors of coding_set_source and coding_set_destination.
1826 All callers that need an offset changed to use these new functions.
1828 2012-05-26 Glenn Morris <rgm@gnu.org>
1830 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
1832 2012-05-26 Eli Zaretskii <eliz@gnu.org>

1835 * xdisp.c (draw_row_with_mouse_face):
1836 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
1838 * w32console.c: Include window.h.
1839 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
1841 (initialize_w32_display): Initialize mouse-highlight data.
1843 * w32inevt.c: Include termchar.h and window.h.
1844 (do_mouse_event): Support mouse-autoselect-window. When the mouse
1845 moves, call note_mouse_highlight. If help_echo changed, call
1846 gen_help_event to produce help-echo message in the echo area.
1847 Call clear_mouse_face if mouse_face_hidden is set in the mouse
1850 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
1852 * lread.c (read1): Simplify slightly to avoid an overflow warning
1853 with GCC 4.7.0 on x86-64.
1855 2012-05-26 Eli Zaretskii <eliz@gnu.org>
1857 * bidi.c (bidi_mirror_char): Revert last change: an int is
1858 definitely wide enough here.
1860 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
1862 Fix integer width and related bugs (Bug#9874).

1872 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
1873 (allocate_pseudovector):
1874 Use int, not EMACS_INT, where int is wide enough.
1875 (inhibit_garbage_collection, Fgarbage_collect):
1876 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
1877 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
1878 int might not be wide enough.
1879 (bidi_cache_search, bidi_cache_find, bidi_init_it)

1882 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
1883 (bidi_level_of_next_char, bidi_move_to_visually_next):
1884 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
1885 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)

1887 (advance_to_char_boundary, Fbuffer_swap_text)
1888 (Fset_buffer_multibyte, overlays_at, overlays_in)
1889 (overlay_touches_p, struct sortvec, record_overlay_string)
1890 (overlay_strings, recenter_overlay_lists)
1891 (adjust_overlays_for_insert, adjust_overlays_for_delete)
1892 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
1893 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
1894 (Foverlay_recenter, last_overlay_modification_hooks_used)
1895 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
1896 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
1897 (validate_region): Omit unnecessary test for b <= e,
1898 since that's guaranteed by the previous test.
1899 (adjust_overlays_for_delete): Avoid pos + length overflow.
1900 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
1901 (report_overlay_modification):

1903 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
1904 Omit pointer cast, which isn't needed anyway, and doesn't work
1905 after the EMACS_INT -> ptrdiff_t change.
1906 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
1907 * buffer.h: Adjust decls to match defn changes elsewhere.
1908 (struct buffer_text, struct buffer):
1909 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
1910 Use EMACS_INT, not int, where int might not be wide enough.
1911 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
1912 not int, to avoid needless 32-bit limit on 64-bit hosts.
1913 (exec_byte_code): Use tighter memory-full test, one that checks
1914 for alloca overflow. Don't compute the address of the object just
1915 before an array, as that's not portable. Use EMACS_INT, not
1916 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
1917 * callint.c (Fcall_interactively):
1918 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
1919 * callproc.c (call_process_kill, Fcall_process):
1920 Don't assume pid_t fits into an Emacs fixnum.
1921 (call_process_cleanup, Fcall_process, child_setup):

1928 * casefiddle.c (casify_object, casify_region, operate_on_word)
1929 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
1930 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
1931 (casify_object): Avoid integer overflow when overallocating buffer.
1932 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
1933 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
1934 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
1935 * category.h (CATEGORYP): Don't assume arg is nonnegative.
1936 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
1937 integers are now checked earlier. All uses replaced with XINT.
1939 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
1940 For CCL_MapSingle, check that content and value are in int range.

1942 Check that Vcode_version_map_vector is a vector.
1943 (resolve_symbol_ccl_program): Check that vector header is in range.
1944 Always copy the vector, so that we can check its contents reliably
1945 now rather than having to recheck each instruction as it's being
1946 executed. Check that vector words fit in 'int'.
1947 (ccl_get_compiled_code, Fregister_ccl_program)
1948 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
1949 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

1951 contents are in range.
1952 (Fccl_execute_on_string): Check that status is in range.
1953 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
1954 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
1955 Accept and return EMACS_INT, not int, because callers can pass values

1962 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

1964 avoid mishandling large integers.

1996 Don't assume fixnum fits in int.

2647 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
2648 short is wide enough.
2649 (x_send_client_event): Don't assume fixnum fits in int.
2650 * xterm.c (x_x_to_emacs_modifiers):
2651 Don't assume EMACS_INT overflows nicely into int.
2652 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
2654 (handle_one_xevent): NATNUMP can eval its arg twice.
2655 (x_connection_closed):
2656 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2657 * xterm.h: Adjust decls to match defn changes elsewhere.
2658 (struct scroll_bar): Use struct vectorlike_header
2659 rather than rolling our own approximation.
2660 (SCROLL_BAR_VEC_SIZE): Remove; not used.
2662 2012-05-25 Glenn Morris <rgm@gnu.org>
2664 * lisp.mk (lisp): Update for more files being compiled now.
2666 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
2668 * lread.c: Remove `read_pure' which makes no difference.
2669 (read_pure): Remove var.
2670 (unreadpure): Remove function.
2671 (readevalloop): Don't call read_list with -1 flag.
2672 (read1, read_vector): Don't test read_pure any more.
2673 (read_list): Simplify.
2675 * fileio.c, character.h: Minor style tweaks.
2677 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
2679 * window.h (clip_changed): Remove useless declaration.
2681 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
2683 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
2684 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
2686 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
2689 This directory predates autoconf and is no longer needed nowadays.
2690 Move its few remaining bits of functionality to where they're needed.
2691 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
2692 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
2693 * m/template.h: Remove.
2694 * Makefile.in (M_FILE): Remove. All uses removed.
2695 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
2696 * lisp.h (USE_LSB_TAG):
2697 * mem-limits.h (EXCEEDS_LISP_PTR):
2698 Use VAL_MAX, not VALBITS, in #if.
2699 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
2700 (EMACS_UINT): Define unconditionally now.
2701 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
2702 (BITS_PER_EMACS_INT): New constants, replacing
2703 what used to be in config.h, but not useful in #if.
2704 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
2705 define them any more.
2706 (VAL_MAX): New macro.
2708 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
2709 BITS_PER_EMACS_INT, in #if.
2710 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
2711 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
2712 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
2713 * s/ms-w32.h (DATA_START):
2714 Move here from removed file m/intel386.h.
2715 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
2716 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
2718 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
2720 Assume C89 or later.
2721 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
2722 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
2724 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
2725 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
2726 * textprop.c, tparam.c (NULL): Remove.
2727 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
2728 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
2729 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
2730 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
2731 * xterm.c (input_signal_count): Assume volatile works.
2733 2012-05-21 Ken Brown <kbrown@cornell.edu>
2735 * xgselect.c (xg_select): Fix first argument in call to 'select'
2738 2012-05-20 Ken Brown <kbrown@cornell.edu>
2740 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
2741 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
2743 2012-05-19 Ken Brown <kbrown@cornell.edu>
2745 * xfns.c (x_in_use): Remove `static' qualifier.
2746 * xterm.h (x_in_use): Declare.
2747 * xgselect.c: Include xterm.h.
2748 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
2749 and `display_arg' (bug#9754).
2751 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
2753 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
2755 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
2756 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
2758 2012-05-18 Eli Zaretskii <eliz@gnu.org>
2760 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
2762 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
2763 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c
2765 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
2766 reference to image_cache->refcount.
2767 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
2769 2012-05-17 Juri Linkov <juri@jurta.org>
2771 * search.c (Fword_search_regexp, Fword_search_backward)
2772 (Fword_search_forward, Fword_search_backward_lax)
2773 (Fword_search_forward_lax): Move functions to isearch.el
2774 (bug#10145, bug#11381).
2776 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
2778 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
2780 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
2782 * lread.c (init_obarray): Declare Qt and Qnil as special.
2784 2012-05-14 Glenn Morris <rgm@gnu.org>
2786 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
2787 Put "libexec" before "bin", for the sake of init_callproc_1.
2789 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
2791 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
2793 * unexaix.c: Port to more-recent AIX compilers.
2794 (report_error, report_error_1, make_hdr, copy_sym)
2795 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
2796 Make arguments const char *, not char *, to avoid violations of C
2797 standard and to fix some AIX warnings reported by Gilles Pion.
2799 2012-05-14 Eli Zaretskii <eliz@gnu.org>
2801 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
2802 already have overlays loaded.
2803 (handle_single_display_spec): Before returning without displaying
2804 fringe bitmap, synchronize the bidi iterator with the main display
2805 iterator, by calling iterate_out_of_display_property.
2806 (iterate_out_of_display_property): Detect buffer iteration by
2807 testing that it->string is a Lisp string.
2808 (get_next_display_element): When the current object is exhausted,
2809 and there's something on it->stack, call set_iterator_to_next to
2810 proceed with what's on the stack, instead of returning zero.
2811 (set_iterator_to_next): If called at the end of a Lisp string,
2812 proceed to consider_string_end without incrementing string
2813 position. Don't increment display vector index past the end of
2814 the display vector. (Bug#11417)
2815 (pos_visible_p): Don't report a position visible when move_it_to
2816 stopped at the last line of window, which happens to be scanned
2817 backwards by the bidi iteration. (Bug#11464)
2819 2012-05-14 Eli Zaretskii <eliz@gnu.org>
2821 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
2822 and right-margin display specs even if the spec is invalid or we
2823 are on a TTY, and thus unable to display on the fringes.
2824 That's because the text with the property will not be displayed anyway,
2825 so we need to signal to the caller that this is a "replacing"
2826 display spec. This fixes display when the spec is invalid or we
2829 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
2831 * unexaix.c (make_hdr): Fix typo in prototype.
2832 This bug broke the build on AIX. Problem reported by Gilles Pion.
2834 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
2836 * keyboard.c (kbd_buffer_get_event): Read special events also in
2837 batch mode. (Bug#11415)
2839 2012-05-12 Glenn Morris <rgm@gnu.org>
2841 * ns.mk: Update for ns_appbindir no longer having trailing "/".
2843 2012-05-12 Eli Zaretskii <eliz@gnu.org>
2845 * lisp.mk (lisp): Add newcomment.elc.
2847 2012-05-12 Glenn Morris <rgm@gnu.org>
2849 * Makefile.in (MKDIR_P): New, set by configure.
2850 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
2852 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
2854 Remove unused function hourglass_started.
2855 * dispextern.h (hourglass_started):
2856 * w32fns.c (hourglass_started):
2857 * xdisp.c (hourglass_started): Remove.
2859 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
2861 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
2862 Update dependencies.
2864 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
2866 * xgselect.c (xg_select): Put maxfds+1 into a var.
2867 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
2869 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
2871 2012-05-10 Dave Abrahams <dave@boostpro.com>
2873 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
2874 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
2876 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
2878 * dbusbind.c (xd_registered_buses): New internal Lisp object.
2879 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
2880 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
2881 Initialize xd_registered_buses.
2883 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
2885 Untag more efficiently if USE_LSB_TAG.
2886 This is based on a proposal by YAMAMOTO Mitsuharu in
2887 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
2888 For an admittedly artificial (nth 8000 longlist) benchmark on
2889 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
2890 Emacs's overall text size by 1%.
2891 * lisp.h (XUNTAG): New macro.
2892 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
2893 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
2894 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
2895 * eval.c (Fautoload):
2896 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
2897 * frame.h (XFRAME): Use XUNTAG.
2899 Port recent dbusbind.c changes to 32-bit --with-wide-int.
2900 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
2901 Remove unportable assumptions about print widths of types like
2903 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
2904 intptr_t when converting between pointer and integer, to avoid GCC
2905 warnings about wrong width.
2907 2012-05-09 Eli Zaretskii <eliz@gnu.org>
2909 * w32proc.c (new_child): Force Windows to reserve only 64KB of
2910 stack for each reader_thread, instead of defaulting to 8MB
2911 determined by the linker. This avoids failures in creating
2912 subprocesses on Windows 7, see the discussion in this thread:
2913 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
2915 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
2917 Fix up display of the *Minibuf-0* buffer in the mini window.
2918 * keyboard.c (read_char): Don't clear the echo area if there's no
2920 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
2921 contents of *Minibuf-0*) if there's no message displayed in its stead.
2923 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
2925 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
2928 2012-05-06 Chong Yidong <cyd@gnu.org>
2930 * lisp.mk (lisp): Update.
2932 2012-05-05 Jim Meyering <meyering@redhat.com>
2934 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
2936 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
2938 * data.c (PUT_ERROR): New macro.
2939 (syms_of_data): Use it. Add new error type `user-error'.
2940 * undo.c (user_error): New function.
2941 (Fprimitive_undo): Use it.
2942 * print.c (print_error_message): Adjust print style for `user-error'.
2943 * keyboard.c (user_error): New function.
2944 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
2946 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
2948 Do not limit current-time-string to years 1000..9999.
2949 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
2950 (Fcurrent_time_string): Support any year that is supported by the
2951 underlying localtime representation. Don't use asctime, as it
2952 has undefined behavior for years outside the range -999..9999.
2954 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
2956 Fix race conditions involving setenv, gmtime, localtime, asctime.
2957 Without this fix, interrupts could mess up code that uses these
2958 nonreentrant functions, since setting TZ invalidates existing
2959 tm_zone or tzname values, and since most of these functions return
2960 pointers to static storage.
2961 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
2962 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
2963 Grow the critical sections to include not just invoking
2964 localtime/gmtime, but also accessing these functions' results
2965 including their tm_zone values if any, and any related TZ setting.
2966 (format_time_string): Last arg is now struct tm *, not struct tm **,
2967 so that the struct tm is saved in the critical section.
2968 All callers changed. Simplify allocation of initial buffer, partly
2969 motivated by the fact that memory allocation needs to be outside
2970 the critical section.
2972 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
2974 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
2975 with RESET_INTERVAL.
2977 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
2978 Remove duplicated buffer name initialization.
2980 2012-05-02 Jim Meyering <jim@meyering.net>
2982 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
2984 * xfns.c (x_window): Use xstrdup (Bug#11375).
2986 2012-05-02 Eli Zaretskii <eliz@gnu.org>
2988 * xdisp.c (pos_visible_p): If already at a newline from the
2989 display string before the 'while' loop, don't walk back the glyphs
2990 from it3.glyph_row. Solves assertion violation when the display
2991 string begins with a newline (egg.el). (Bug#11367)
2993 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
2995 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
2998 2012-05-01 Glenn Morris <rgm@gnu.org>
3000 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3001 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3002 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3003 All were removed before 23.1.
3005 * dispnew.c: Remove HAVE_LIBNCURSES test;
3006 it is always true on relevant platforms.
3008 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3009 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3011 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3013 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3015 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3016 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3019 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3021 Do not avoid creating empty evaporating overlays (Bug#9642).
3022 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3023 That is, do not delete an evaporating overlay if it becomes
3024 empty after its bounds are adjusted to fit within its buffer.
3025 This fix caused other problems, and I'm reverting it until we get
3026 to the bottom of them.
3028 2012-04-27 Chong Yidong <cyd@gnu.org>
3030 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3032 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3034 * xdisp.c (pos_visible_p): If the window start position is beyond
3035 ZV, start the display from buffer beginning. Prevents assertion
3036 violation in init_iterator when the minibuffer window is scrolled
3039 * window.c (window_scroll_pixel_based): Likewise.
3041 2012-04-27 Chong Yidong <cyd@gnu.org>
3043 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3045 2012-04-27 Glenn Morris <rgm@gnu.org>
3047 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3048 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3050 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3052 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3053 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3055 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3057 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3058 display element, check also the underlying string or buffer
3059 character. (Bug#11341)
3061 * w32menu.c: Include w32heap.h.
3062 (add_menu_item): If the call to AppendMenuW (via
3063 unicode_append_menu) fails, disable Unicode menus only if we are
3064 running on Windows 9X/Me.
3066 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3068 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3069 (xgetint): Add missing shift for LSB tags.
3071 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3073 * keyboard.c (read_char): Don't wipe echo area for select window
3074 events: These might get delayed via `mouse-autoselect-window'
3077 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
3079 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
3080 manipulation of :loaded-from data.
3082 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
3084 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
3085 now a cons (bug#11311).
3087 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
3089 Do not create empty overlays with the evaporate property (Bug#9642).
3090 * buffer.c (Fmove_overlay): Delete an evaporating overlay
3091 if it becomes empty after its bounds are adjusted to fit within
3092 its buffer. Without this fix, in a nonempty buffer (let ((o
3093 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
3094 yields an empty overlay that has the evaporate property, which is
3095 not supposed to happen.
3097 Fix minor GTK3 problems found by static checking.
3098 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
3099 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
3100 (struct _EmacsFixedClass, emacs_fixed_get_type):
3101 Move decls here from emacsgtkfixed.h, since they needn't be public.
3102 (emacs_fixed_get_type): Now static.
3103 (emacs_fixed_class_init): Omit unused local.
3104 (emacs_fixed_child_type): Remove; unused.

3199 since the two debugging options are incompatible.
3200 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
3202 (mem_init, mem_insert, mem_insert_fixup):
3203 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

3296 New extern decls, to avoid calling undeclared functions.
3297 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
3298 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
3299 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

3369 2012-04-11 Daniel Colascione <dancol@dancol.org>
3371 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
3372 against is gone. It's better to use vfork now so that when Cygwin
3373 gains a new, working vfork, we use it automatically (bug#10398).
3375 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

3430 2012-04-09 Eli Zaretskii <eliz@gnu.org>
3432 * xdisp.c (set_cursor_from_row): If the display string appears in
3433 the buffer at position that is closer to point than the position
3434 after the display string, display the cursor on the first glyph of
3435 the display string. Fixes cursor display when a 'display' text
3436 property immediately follows invisible text. (Bug#11094)
3438 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
3440 composite.c: use 'double' consistently
3441 * composite.c (get_composition_id): Use 'double' consistently
3442 instead of converting 'float' to 'double' and vice versa; this is
3443 easier to understand and avoids a GCC warning.
3445 2012-04-09 Glenn Morris <rgm@gnu.org>
3447 * Makefile.in: Generate leim-list with bootstrap-emacs, in

3492 [!WINDOWSNT]: New macros.
3493 (init_libxml2_functions, libxml2_loaded_p): New functions.
3494 (parse_region): Call fn_xmlCheckVersion instead of using the macro
3495 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
3496 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.

3517 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
3518 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
3519 about subtle differences between FETCH_CHAR* and STRING_CHAR*
3520 macros related to unification of CJK characters. For the details,
3521 see the discussion following the message here:
3522 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
3524 2012-04-04 Chong Yidong <cyd@gnu.org>

3540 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
3541 position we get to after a call to move_it_to fails the
3542 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
3543 only if we wind up in a string from display property. (Bug#11063)
3545 * window.c (Fdelete_other_windows_internal): Invalidate the row
3546 and column information about mouse highlight, so that redisplay
3547 restores it after reallocating the glyph matrices. (Bug#7464)
3549 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
3550 string comes from a `display' text property, use the buffer
3551 position of that property as if we actually saw that position in
3553 (move_it_by_lines): Remove the assertion that
3554 "it->current_x == 0 && it->hpos == 0" which can be legitimately
3555 violated when there's a before-string at the beginning of a line.
3558 2012-03-30 Eli Zaretskii <eliz@gnu.org>
3560 * xdisp.c (append_space_for_newline): If the default face was
3561 remapped, use the remapped face for the appended newline.
3562 (extend_face_to_end_of_line): Use the remapped default face for
3563 extending the face to the end of the line.
3564 (display_line): Call extend_face_to_end_of_line when the default
3565 face was remapped. (Bug#11068)
3567 2012-03-29 Eli Zaretskii <eliz@gnu.org>
3569 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
3571 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
3573 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
3575 2012-03-27 Glenn Morris <rgm@gnu.org>
3577 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
3580 2012-03-26 Kenichi Handa <handa@m17n.org>
3582 * dispextern.h (struct glyph): Fix previous change. Change the
3583 bit length of glyphless.ch to 25 (Bug#11082).
3585 2012-03-26 Chong Yidong <cyd@gnu.org>
3587 * keyboard.c (Vselection_inhibit_update_commands): New variable.
3588 (command_loop_1): Use it; inhibit selection update for
3589 handle-select-window too (Bug#8996).
3591 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
3593 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
3595 2012-03-25 Kenichi Handa <handa@m17n.org>
3597 * dispextern.h (struct glyph): Change the bit length of
3598 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
3600 2012-03-24 Eli Zaretskii <eliz@gnu.org>
3602 * s/ms-w32.h (tzname): Include time.h before redirecting to
3603 _tzname. Fixes the MSVC build. (Bug#9960)
3605 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
3607 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
3610 * xterm.c (XTread_socket): Only modify handling_signal if
3611 !SYNC_INPUT. (Bug#11080)
3613 2012-03-23 Eli Zaretskii <eliz@gnu.org>
3615 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
3616 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
3617 when fetching a multibyte character consumes more bytes than
3618 CHAR_BYTES returns, due to unification of CJK characters in
3619 string_char. (Bug#11073)
3621 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
3623 * process.c (wait_reading_process_output): Handle pty disconnect
3624 by refraining from sending oneself a SIGCHLD (bug#10933).
3626 2012-03-22 Chong Yidong <cyd@gnu.org>
3628 * dispextern.h (struct it): New member string_from_prefix_prop_p.
3630 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
3631 Mark string as coming from a prefix property.
3632 (handle_face_prop): Use default face for prefix strings (Bug#4281).
3633 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
3635 2012-03-21 Chong Yidong <cyd@gnu.org>
3637 * xfaces.c (Vface_remapping_alist): Doc fix.
3639 2012-03-20 Eli Zaretskii <eliz@gnu.org>
3641 * w32proc.c (Fw32_set_console_codepage)
3642 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
3645 2012-03-20 Chong Yidong <cyd@gnu.org>
3647 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
3648 to reflect default non-nil value of redisplay-dont-pause.
3650 2012-03-19 Kenichi Handa <handa@m17n.org>
3652 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
3653 it fit in a valid range (Bug#11003).
3655 2012-03-18 Eli Zaretskii <eliz@gnu.org>
3657 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
3658 that is not from display property, accept the row as a "cursor
3659 row" if one of the string's character has a non-nil `cursor'
3660 property. Fixes cursor positioning when there are newlines in
3661 overlay strings, e.g. in icomplete.el. (Bug#11035)
3663 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
3665 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
3667 2012-03-12 Chong Yidong <cyd@gnu.org>
3669 * eval.c (inhibit_lisp_code): Rename from
3670 inhibit_window_configuration_change_hook; move from window.c.
3672 * xfns.c (unwind_create_frame_1, Fx_create_frame):
3673 * window.c (run_window_configuration_change_hook)
3674 (syms_of_window): Callers changed.
3676 2012-03-11 Chong Yidong <cyd@gnu.org>

3685 is visible (Bug#10955).
3687 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
3689 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
3691 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
3693 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
3694 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
3697 2012-03-03 Glenn Morris <rgm@gnu.org>
3699 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
3701 2012-03-02 Eli Zaretskii <eliz@gnu.org>
3703 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
3704 position past the first glyph_row that ends at ZV. (Bug#10902)
3705 (redisplay_window, next_element_from_string): Fix typos in
3707 (redisplay_window): Pass to move_it_vertically the margin in
3708 pixels, not in screen lines.
3710 2012-03-02 Glenn Morris <rgm@gnu.org>
3712 * buffer.c (buffer-list-update-hook): Doc fix.
3714 2012-02-29 Eli Zaretskii <eliz@gnu.org>
3716 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
3717 push_it before setting up the iterator for the first overlay
3718 string, even if we have an empty string loaded.
3719 (next_overlay_string): If there's an empty string on the iterator
3720 stack, pop the stack. (Bug#10903)
3722 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
3724 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
3725 Suggested by Stefan Monnier in
3726 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
3727 * alloc.c (widen_to_Lisp_Object): New static function.
3728 (mark_memory): Also mark Lisp_Objects by fetching pointer words
3729 and widening them to Lisp_Objects. This would work even if
3730 USE_LSB_TAG is defined and wide integers are used, which might
3731 happen in a future version of Emacs.
3733 2012-02-25 Chong Yidong <cyd@gnu.org>
3735 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
3738 * xselect.c (Fx_selection_exists_p): Doc fix.
3739 (x_clipboard_manager_save_all): Print an informative message
3740 before saving to clipboard manager.
3742 2012-02-24 Chong Yidong <cyd@gnu.org>
3744 * keyboard.c (process_special_events): Handle all X selection
3745 requests in kbd_buffer, not just the next one (Bug#8869).
3747 2012-02-23 Chong Yidong <cyd@gnu.org>
3749 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
3750 call when setting menu-bar-lines and tool-bar-lines parameters.
3751 (unwind_create_frame_1): New helper function.
3753 * window.c (inhibit_window_configuration_change_hook): New var.
3754 (run_window_configuration_change_hook): Obey it.
3755 (syms_of_window): Initialize it.
3757 2012-02-22 Chong Yidong <cyd@gnu.org>
3759 * xterm.c (x_draw_image_relief): Add missing type check for
3760 Vtool_bar_button_margin (Bug#10743).

3764 * fileio.c (Vfile_name_handler_alist): Doc fix.
3766 * buffer.c (Fget_file_buffer): Protect against invalid file
3767 handler return value.
3769 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
3771 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
3772 when computing $valmask.
3774 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
3775 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
3776 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
3777 It's useless in that case, and it can cause problems on hosts
3778 that allocate halves of EMACS_INT values separately.
3779 Reported by Dan Horák. Diagnosed by Andreas Schwab in
3780 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
3781 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
3782 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
3783 it avoids undefined behavior on hosts where shifting right by more
3784 than the word width has undefined behavior.
3786 2012-02-19 Chong Yidong <cyd@gnu.org>
3788 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
3789 (Funhandled_file_name_directory, Ffile_name_as_directory)
3790 (Fdirectory_file_name, Fexpand_file_name)
3791 (Fsubstitute_in_file_name): Protect against invalid file handler
3792 return values (Bug#10845).
3794 2012-02-18 Eli Zaretskii <eliz@gnu.org>
3796 * .gdbinit (pitx): Fix incorrect references to fields of the
3799 2012-02-17 Chong Yidong <cyd@gnu.org>

3803 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
3805 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
3806 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
3808 2012-02-15 Chong Yidong <cyd@gnu.org>
3810 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
3811 marked as special. Also, starting docstrings with * is obsolete.
3813 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
3815 * gnutls.c (emacs_gnutls_write): Fix last change.
3817 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

3826 2012-02-12 Chong Yidong <cyd@gnu.org>
3828 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
3829 as that creates a dangerous corner case.
3831 * window.c (Fdelete_window_internal): Invalidate the mouse
3832 highlight (Bug#9904).
3834 2012-02-12 Glenn Morris <rgm@gnu.org>
3836 * xselect.c (Fx_own_selection_internal)
3837 (Fx_get_selection_internal, Fx_disown_selection_internal)
3838 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
3839 * nsselect.m (Fx_own_selection_internal)
3840 (Fx_disown_selection_internal, Fx_selection_exists_p)
3841 (Fx_selection_owner_p, Fx_get_selection_internal):
3842 Sync docs and argument specs with the xselect.c versions.
3844 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
3846 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
3848 2012-02-11 Eli Zaretskii <eliz@gnu.org>

3860 2012-02-09 Kenichi Handa <handa@m17n.org>
3862 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
3864 2012-02-07 Chong Yidong <cyd@gnu.org>
3866 * buffer.c (Fbuffer_local_variables)
3867 (buffer_lisp_local_variables): Handle unbound vars correctly;
3868 don't let Qunbound leak into Lisp.
3870 2012-02-07 Glenn Morris <rgm@gnu.org>
3872 * image.c (Fimagemagick_types): Doc fix.
3874 * image.c (imagemagick-render-type): Change it from a lisp object
3875 to an integer. Move the doc here from the lisp manual.
3876 Treat all values not equal to 0 the same.
3878 2012-02-06 Chong Yidong <cyd@gnu.org>
3880 * doc.c (store_function_docstring): Avoid applying docstring of
3881 alias to base function (Bug#2603).
3883 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
3885 * .gdbinit (pp1, pv1): Remove redundant defines.
3888 2012-02-04 Chong Yidong <cyd@gnu.org>
3890 * nsterm.m: Declare a global (Bug#10694).
3892 2012-02-04 Eli Zaretskii <eliz@gnu.org>
3894 * w32.c (get_emacs_configuration_options):
3895 Include --enable-checking, if specified, in the return value.
3897 2012-02-04 Martin Rudalics <rudalics@gmx.at>
3899 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
3900 after rounding frame sizes. (Bug#9723)
3902 2012-02-04 Eli Zaretskii <eliz@gnu.org>
3904 * keyboard.c (adjust_point_for_property): Don't position point
3905 before BEGV. (Bug#10696)
3907 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
3909 Handle overflow when computing char display width (Bug#9496).
3910 * character.c (char_width): Return EMACS_INT, not int.
3911 (char_width, c_string_width): Check for overflow when
3912 computing the width; this is possible now that individual
3913 characters can have unbounded width. Problem introduced
3914 by merge from Emacs 23 on 2012-01-19.
3916 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
3918 * dbusbind.c (Fdbus_register_method): Mention the return value
3919 :ignore in the docstring.
3921 2012-02-02 Glenn Morris <rgm@gnu.org>
3923 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

3931 2012-02-02 Kenichi Handa <handa@m17n.org>
3933 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
3934 0, do not call append_composite_glyph.
3936 2012-02-02 Kenichi Handa <handa@m17n.org>
3938 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
3940 (x_produce_glyphs): If the component of a composition is a null
3941 string, set it->pixel_width to 1 to avoid zero-width glyph.
3943 2012-02-01 Eli Zaretskii <eliz@gnu.org>
3945 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
3946 first 2 arguments are identical. This makes inserting large
3947 output from a subprocess an order of magnitude faster on
3948 MS-Windows, where all sbrk'ed memory is always contiguous.
3950 2012-01-31 Glenn Morris <rgm@gnu.org>
3952 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

3960 2012-01-28 Samuel Thibault <sthibault@debian.org> (tiny change)
3962 * s/gnu.h: Define POSIX_SIGNALS (Bug#10552).
3964 2012-01-28 Chong Yidong <cyd@gnu.org>
3966 * minibuf.c (syms_of_minibuf): Doc fix (Bug#10550).
3968 2012-01-26 Chong Yidong <cyd@gnu.org>

3988 2012-01-21 Chong Yidong <cyd@gnu.org>
3990 * floatfns.c (Fcopysign): Make the second argument non-optional,
3991 since nil is not allowed anyway.
3993 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
3995 * process.c (read_process_output): Use p instead of XPROCESS (proc).
3996 (send_process): Likewise.

4002 Rewrite doc-strings.
4004 2012-01-19 Kenichi Handa <handa@m17n.org>
4006 * character.c (char_width): New function.
4007 (Fchar_width, c_string_width, lisp_string_width):
4008 Use char_width (Bug#9496).
4010 2012-01-16 Martin Rudalics <rudalics@gmx.at>
4012 * window.c (Vwindow_persistent_parameters): New variable.
4013 (Fset_window_configuration, save_window_save): Handle persistent
4016 2012-01-14 Eli Zaretskii <eliz@gnu.org>
4018 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
4019 thrashing the stack of the thread. (Bug#9087)
4021 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
4023 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.

4027 * xdisp.c (rows_from_pos_range): Handle the case where the
4028 highlight ends on a newline. (Bug#10464)
4029 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
4030 he end column for display of highlight that ends on a newline
4033 2012-01-11 Glenn Morris <rgm@gnu.org>
4035 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
4036 from load-path also when installation-directory is nil. (Bug#10208)
4038 2012-01-10 Glenn Morris <rgm@gnu.org>
4040 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
4042 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
4043 Update template values to be closer to their typical values these days.
4045 2012-01-09 Eli Zaretskii <eliz@gnu.org>
4047 * xdisp.c (rows_from_pos_range): Accept additional argument
4048 DISP_STRING, and accept any glyph in a row whose object is that
4049 string as eligible for mouse highlight. Fixes mouse highlight of
4050 display strings from overlays. (Bug#10464)
4052 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
4054 emacs: fix an auto-save permissions race condition (Bug#10400)
4055 * fileio.c (auto_saving_dir_umask): New static var.
4056 (Fmake_directory_internal): Use it.
4057 (do_auto_save_make_dir): Set it, instead of invoking chmod after
4058 creating the directory. The old code temporarily assigns
4059 too-generous permissions to the directory.
4060 (do_auto_save_eh): Clear it.

4563 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
4564 Otherwise, valgrind does not work on some platforms.
4565 Problem reported by Andreas Schwab in
4566 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
4567 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
4568 is set, removing the need for VIRT_ADDRESS_VARIES.
4569 (PURE_P): Use a more-efficient implementation that needs just one
4570 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
4571 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
4572 to 4 (xorl, subq, cmpq, setbe).
4573 * alloc.c (pure): Always extern now, since that's the
4574 VIRT_ADDR_VARIES behavior.
4575 (PURE_POINTER_P): Use a single comparison, not two, for
4576 consistency with the new puresize.h.
4577 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
4578 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
4579 Remove VIRT_ADDR_VARIES no longer needed.

4584 (erase_phys_cursor, update_window_cursor, show_mouse_face)
4585 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
4586 behave as if the cursor position were at the window margin.
4588 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
4589 and the cursor position is out of bounds, behave as if the cursor
4590 position were at the window margin. (Bug#10075)
4592 2011-11-18 Chong Yidong <cyd@gnu.org>
4594 * window.c (Fwindow_combination_limit): Make first argument

4617 (compute_line_metrics): Call row_hash, instead of computing the
4620 * dispnew.c (verify_row_hash): Call row_hash for computing the
4621 hash code of a row, instead of duplicating code from xdisp.c.

4659 * image.c (imagemagick_load_image): Fix typo.
4661 2011-11-14 Eli Zaretskii <eliz@gnu.org>
4663 * xdisp.c (display_line): Move the call to
4664 highlight_trailing_whitespace before the call to
4665 compute_line_metrics, since the latter needs to see the final
4666 faces of all the glyphs to compute ROW's hash value.
4667 Fixes assertion violations in row_equal_p. (Bug#10035)
4669 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

4677 with user-defined heap size. Bump the default size of the temacs
4678 heap to 27MB, to avoid memory warning when running temacs.
4679 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
4681 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

4730 Avoid some portability problems by eschewing 'extern inline' functions.
4731 The trivial performance wins aren't worth the portability hassles; see
4732 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
4734 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

4736 (window_box_right, window_box_right_offset): Undo previous change,
4737 by removing the "extern"s.
4738 * intervals.c (adjust_intervals_for_insertion)
4739 (adjust_intervals_for_deletion): Undo previous change,
4740 making these static again.
4741 (offset_intervals, temp_set_point_both, temp_set_point)
4742 (copy_intervals_to_string): No longer inline.

4811 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
4812 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
4813 * intervals.c (adjust_intervals_for_insertion)
4814 (adjust_intervals_for_deletion): Now extern, because otherwise the
4815 extern inline functions 'offset_intervals' couldn't refer to it.
4816 (static_offset_intervals): Remove.
4817 (offset_intervals): Rewrite using the old contents of
4818 static_offset_intervals. The old version didn't conform to C99
4819 because an extern inline function contained a reference to an
4820 identifier with static linkage.

4842 (Fwindow_vscroll): Doc fix.
4843 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
4844 argument, since it makes no sense to pass a live window and for
4845 consistency with window-child.

4873 (unwind_create_frame): New function (Bug#9943).
4874 (Fx_create_frame): Restructure code to be more similar to the one in
4875 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
4876 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
4877 Move terminal->reference_count++ just before making the frame official

5028 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
5030 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
5032 * window.c (make_window): Initialize phys_cursor_on_p.
5034 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5036 * lisp.h (struct Lisp_Symbol): Update comments.
5038 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
5040 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
5042 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5044 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
5045 <oslsachem@gmail.com> for helping to debug this.
5047 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
5048 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
5049 (g_b_init_get_glyph_outline_w): New static variables.
5050 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
5051 (GetGlyphOutlineW_Proc): New typedefs.
5052 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
5053 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
5055 (w32font_open_internal, compute_metrics):
5056 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
5057 instead of calling the "wide" APIs directly.
5059 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
5061 * w32.h (syms_of_w32font): Add prototype.
5063 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5065 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
5066 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
5067 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
5068 (Fmove_to_window_line): Doc fix.
5070 2011-10-27 Chong Yidong <cyd@gnu.org>
5072 * process.c (make_process): Set gnutls_state to NULL.
5074 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
5075 non-NULL, regardless of GNUTLS_INITSTAGE.
5076 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
5077 an error. Set process slots as soon as we allocate them.
5079 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
5081 2011-10-27 Chong Yidong <cyd@gnu.org>
5083 * gnutls.c (emacs_gnutls_deinit): New function.
5084 Deallocate credentials structures as well as calling gnutls_deinit.
5085 (Fgnutls_deinit, Fgnutls_boot): Use it.
5087 * process.c (make_process): Initialize GnuTLS credentials to NULL.
5088 (deactivate_process): Call emacs_gnutls_deinit.
5090 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5092 * image.c (x_create_x_image_and_pixmap):
5093 * w32.c (sys_rename, w32_delayed_load):
5094 * w32font.c (fill_in_logfont):
5095 * w32reg.c (x_get_string_resource): Silence compiler warnings.
5097 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
5099 * w32fns.c (w32_default_color_map): New function,
5100 extracted from Fw32_default_color_map.
5101 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
5103 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
5105 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
5107 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
5109 * keyboard.c (test_undefined): New function (bug#9751).
5110 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
5112 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
5114 * sysdep.c (init_sys_modes): Fix the check for the controlling
5115 terminal (Bug#6649).
5117 2011-10-20 Eli Zaretskii <eliz@gnu.org>
5119 * dispextern.h (struct bidi_it): New member next_en_type.
5121 * bidi.c (bidi_line_init): Initialize the next_en_type member.
5122 (bidi_resolve_explicit_1): When next_en_pos is valid for the
5123 current character, check also for next_en_type being WEAK_EN.
5124 (bidi_resolve_weak): Don't enter the expensive loop if the current
5125 position is before next_en_pos. Record the bidi type of the first
5126 non-ET, non-BN character we find, in addition to its position.
5127 (bidi_level_of_next_char): Invalidate next_en_type when
5128 next_en_pos is over-stepped.
5130 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
5132 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
5133 * editfns.c: Rewrite current-time-zone so that it invokes
5134 the equivalent of (format-time-string "%Z") to get the time zone name.
5135 This fixes a bug when the time zone name contains characters that
5136 need converting from the system time locale to Emacs internal format.
5137 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
5138 that patch fixed format-time-string to do the conversion, but
5139 I forgot to fix current-time-zone.
5140 (format_time_string): New function, containing most of
5141 what Fformat_time_string used to contain.
5142 (Fformat_time_string): Rewrite in terms of format_time_string.
5143 This doesn't change this function's behavior.
5144 (current-time-zone): Rewrite to use format_time_string.
5145 This fixes the bug reported by Michael Schierl in
5146 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
5147 Jason Rumney's 2007-06-07 change worked around this bug, but
5149 * systime.h (tzname, timezone): Remove no-longer-used declarations.
5151 2011-10-19 Eli Zaretskii <eliz@gnu.org>
5153 * xdisp.c (start_display): If the character at POS is displayed
5154 via a display vector, reset IT->current.dpvec_index to zero.
5155 (try_window_reusing_current_matrix): If a line ends in a display
5156 vector or the next line starts in a display vector, continue
5157 redrawing the window even though the character position of
5158 start_row was reached.
5161 2011-10-18 Chong Yidong <cyd@gnu.org>
5163 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
5164 with nobreak-char-display too.
5166 2011-10-18 Eli Zaretskii <eliz@gnu.org>
5168 Fix part 3 of bug#9771.
5169 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
5170 (bidi_resolve_neutral): Don't enter the expensive loop looking for
5171 non-neutral characters if the current character is a paragraph
5172 separator (a.k.a. Newline). This avoids running the same
5173 expensive loop twice, once when we consume the preceding newline
5174 and the other time when the line actually needs to be displayed.
5175 Avoid the loop when we see neutrals on the base embedding level
5176 following a character whose directionality is the same as the
5177 paragraph's. This avoids running the expensive loop when a line
5178 ends in a long sequence of neutrals, like control characters.
5179 Add assertion against STRONG_AL type. Slightly rearrange code
5180 that determines the type of a neutral given the first non-neutral
5182 (bidi_level_of_next_char): Set next_en_pos to zero when
5183 invalidating its info.
5185 2011-10-17 Eli Zaretskii <eliz@gnu.org>
5187 * xdisp.c (push_display_prop): Determine whether to record string
5188 or buffer position by IT->string, not by IT->method. Allow
5189 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
5190 (move_it_vertically_backward): Don't look for character position
5191 immediately after the newline when in a continuation line.
5194 2011-10-15 Martin Rudalics <rudalics@gmx.at>
5196 * window.c (coordinates_in_window): Rewrite and delabelize
5197 vertical border check. (Bug#5357) (Bug#9618)
5199 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
5201 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
5202 errors in XSetWindowBorder (bug#9310).
5204 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
5206 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
5207 avoid crash when xmalloc overrun checking is enabled.
5209 2011-10-13 Eli Zaretskii <eliz@gnu.org>
5211 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
5212 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
5213 cursor motion with <left> and <right> arrow keys.
5215 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
5216 some callers set that themselves.
5218 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5220 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
5221 display string and the previous row comes from the same string and
5222 is empty. (Bug#9739) (Bug#9738)
5224 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
5226 * doc.c (get_doc_string): Encode file name (bug#9735).
5228 2011-10-12 Eli Zaretskii <eliz@gnu.org>
5230 * bidi.c (bidi_level_of_next_char):
5231 * xdisp.c (get_visually_first_element): Remove old incorrect
5232 comments regarding the Unicode Line Separator character.
5234 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
5236 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
5238 * alloc.c (Fgc_status): Do not access beyond zombies array
5239 boundary if nzombies > MAX_ZOMBIES.
5240 * alloc.c (dump_zombies): Add missing format specifier.
5242 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
5244 * xdisp.c (set_cursor_from_row): Simplify conditionals,
5245 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
5247 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
5248 Some packages use them to denote characters with modifiers.
5250 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
5252 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
5253 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
5254 matching a pp-number. Rename parameter var to var1.
5256 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
5258 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
5260 2011-10-08 Glenn Morris <rgm@gnu.org>
5262 * callint.c (Fcall_interactively): Give a more explicit error for the
5263 'c' case with a non-character input. (Bug#8479)
5265 2011-10-08 Eli Zaretskii <eliz@gnu.org>
5267 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
5269 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
5270 lines that are hscrolled on the left.
5272 * dispnew.c (buffer_posn_from_coords): Account for a possible
5273 presence of header-line. (Bug#4426)
5275 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
5277 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
5278 Don't advertise functionality which we discourage or doesn't work.
5280 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
5282 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
5283 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
5284 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
5285 this makes Emacs dump core during garbage collection on rare
5286 occasions. sizeof is obviously inferior to offsetof here, so
5287 stick with offsetof.
5288 (GC_POINTER_ALIGNMENT): New macro.
5289 (mark_memory): Omit 3rd (offset) arg; caller changed.
5290 Don't assume EMACS_INT alignment is the same as pointer alignment.
5292 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
5294 * keyboard.c (read_key_sequence_remapped): New var.
5295 (read_key_sequence): Compute remapping in the right buffer.
5296 (command_loop_1): Use read_key_sequence's remapping directly.
5298 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5300 * dired.c (file_name_completion): Don't expand file name.
5301 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
5302 before checking file name handler.
5304 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
5305 they've been requested explicitly (bug#9591).
5307 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
5309 * keymap.c (Fsingle_key_description): Use make_specified_string
5310 instead of build_string to build string from push_key_description.
5313 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5315 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
5316 This fixes a Y2038 bug on 64-bit hosts.
5317 * buffer.c (reset_buffer):
5318 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
5319 (Fclear_buffer_auto_save_failure):
5320 Use 0, not -1, to represent an unset failure time, since time_t
5321 might not be signed.
5323 Remove dependency on glibc malloc internals.
5324 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5325 Move back here from lisp.h, but with their new implementations.
5326 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5327 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
5328 * charset.c (charset_table_init): New static var.
5329 (syms_of_charset): Use it instead of xmalloc. This removes a
5330 dependency on glibc malloc internals. See Eli Zaretskii's comment in
5331 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
5332 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5333 Move back to alloc.c.
5334 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5335 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
5337 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
5339 * nsterm.m (windowDidResize): Call x_set_window_size only when
5340 ns_in_resize is true. Otherwise set pixelwidth/height and
5341 call change_frame_size (Bug#9628).
5343 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
5345 Port --enable-checking=all to Fedora 14 x86-64.
5346 * charset.c (syms_of_charset): Also account for glibc malloc's
5347 internal overhead when calculating the initial malloc maximum.
5349 Port --enable-checking=all to Fedora 14 x86.
5350 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5352 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
5353 (overrun_check_realloc, overrun_check_free):
5354 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
5355 That way, xmalloc returns a properly-aligned pointer even if
5356 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
5357 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
5358 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
5359 into account when calculating the initial malloc maximum.
5360 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
5361 Move here from alloc.c, so that charset.c can use it too.
5362 Properly align; the old code wasn't right for common 32-bit hosts
5363 when configured with --enable-checking=all.
5364 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
5365 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
5367 2011-09-29 Eli Zaretskii <eliz@gnu.org>
5369 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
5372 2011-09-28 Eli Zaretskii <eliz@gnu.org>
5374 * xdisp.c (compute_display_string_end): If there's no display
5375 string at CHARPOS, return -1.
5377 * bidi.c (bidi_fetch_char): When compute_display_string_end
5378 returns a negative value, treat the character as a normal
5379 character not covered by a display string. (Bug#9624)
5381 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
5383 * lread.c (Fread_from_string): Fix typo in docstring.
5385 2011-09-27 Eli Zaretskii <eliz@gnu.org>
5387 * xdisp.c (handle_invisible_prop): If invisible text ends on a
5388 newline, reseat the iterator instead of bidi-iterating there one
5389 character at a time. (Bug#9610)
5390 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
5391 TO_CHARPOS if the bidi iterator is at base embedding level.
5393 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
5395 * lread.c (readevalloop): Use correct code for NBSP.
5396 (read1): Likewise. (Bug#9608)
5398 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
5400 * dbusbind.c (Fdbus_register_signal): When service is not
5401 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
5403 2011-09-25 Glenn Morris <rgm@gnu.org>
5405 * buffer.c (truncate-lines): Doc fix.
5407 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
5409 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
5410 (Fset_window_next_buffers): Doc fix.
5412 2011-09-24 Glenn Morris <rgm@gnu.org>
5414 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
5416 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
5418 Fix minor problems found by static checking.
5419 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
5420 * indent.c (Fvertical_motion): Fix == vs = typo.
5422 2011-09-24 Eli Zaretskii <eliz@gnu.org>
5424 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
5425 Default value is now t. Doc fix.
5427 * indent.c (Fvertical_motion): Compute and apply the overshoot
5428 logic when moving up, not only when moving down. Fix the
5429 confusing name and values of the it_overshoot_expected variable;
5430 logic changes accordingly. (Bug#9254) (Bug#9549)
5432 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
5433 CHARPOS is covered by a display string which includes newlines.
5434 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
5435 is covered by a display string with embedded newlines.
5437 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
5439 * dbusbind.c (Fdbus_register_signal): Add match rule to
5440 Vdbus_registered_objects_table. (Bug#9581)
5441 (Fdbus_register_method, Vdbus_registered_objects_table):
5444 2011-09-24 Jim Meyering <meyering@redhat.com>
5446 do not ignore write error for any output size
5447 The previous change was incomplete.
5448 While it makes emacs --batch detect the vast majority of stdout
5449 write failures, errors were still ignored whenever the output size is
5450 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
5451 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
5452 && echo FAIL: ignored write error
5453 FAIL: ignored write error
5454 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
5455 && echo FAIL: ignored write error
5456 FAIL: ignored write error
5457 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
5459 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
5461 * emacs.c (Fkill_emacs): In noninteractive mode exit
5462 non-successfully if a write error occurred on stdout. (Bug#9574)
5464 2011-09-21 Eli Zaretskii <eliz@gnu.org>
5466 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
5469 * dispextern.h (struct it): Update the comment documenting what
5472 2011-09-20 Eli Zaretskii <eliz@gnu.org>
5474 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
5475 a display string, extend search for cursor position to end of row.
5476 (find_row_edges): If the row ends in a newline from a display
5477 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
5478 Handle the case of a display string with multiple newlines.
5479 (Fcurrent_bidi_paragraph_direction): Fix search for previous
5480 non-empty line. Fixes confusing cursor motion with arrow keys at
5481 the beginning of a line that starts with whitespace.
5483 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
5485 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
5488 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
5490 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
5493 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5495 * xdisp.c (display_line): Record maximum and minimum buffer
5496 positions even if no glyphs were produced (e.g., by a zero-width
5497 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
5498 buffer positions that will be removed from the glyph row because
5500 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
5501 column is beyond frame width: don't subtract 1 "pixel" when
5502 computing width of the stretch.
5503 (reseat_at_next_visible_line_start): Undo the change made on
5504 2011-09-17 that saved paragraph information and restored it after
5505 the call to `reseat'. (Bug#9545)
5507 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5509 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
5510 and turn window cursor on if cleared (Bug#9415).
5512 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
5514 * search.c (boyer_moore): Take unibyte characters from pattern
5515 literally. (Bug#9458)
5517 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5519 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
5521 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
5523 Fix minor problem found by static checking.
5524 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
5525 initialized, to pacify gcc -Wuninitialized.
5527 * fileio.c: Report proper errno when syscall falls.
5528 (Finsert_file_contents): Save and restore errno,
5529 so that report_file_error outputs the correct diagnostic.
5530 (Fwrite_region) [CLASH_DETECTION]: Likewise.
5532 2011-09-18 Eli Zaretskii <eliz@gnu.org>
5534 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
5536 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5538 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
5539 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
5541 2011-09-17 Eli Zaretskii <eliz@gnu.org>
5543 * xdisp.c (reseat_at_next_visible_line_start): Keep information
5544 about the current paragraph and restore it after the call to reseat.
5546 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
5547 (bidi_find_paragraph_start): Search back for paragraph beginning
5548 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
5549 (bidi_move_to_visually_next): Only trigger paragraph-related
5550 computations when the last character is a newline or at EOB, not
5551 just any NEUTRAL_B. (Bug#9470)
5553 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
5554 truncated lines if point is covered by a display string. (Bug#9524)
5556 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
5558 * xselect.c: Relax test for outgoing X longs (Bug#9498).
5559 (cons_to_x_long): New function.
5560 (lisp_data_to_selection_data): Use it. Correct the test for
5561 short-versus-long data; it was negated. Break out of vector
5562 loop, for efficiency, when a long datum is discovered.
5564 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
5566 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
5568 2011-09-16 Eli Zaretskii <eliz@gnu.org>
5570 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
5571 GCC PR/17406) by declaring this function with external scope.
5573 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5575 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
5576 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
5578 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
5580 * editfns.c (Fformat): Correctly handle text properties on "%%".
5582 2011-09-15 Eli Zaretskii <eliz@gnu.org>
5584 * xterm.c (x_draw_composite_glyph_string_foreground):
5585 * w32term.c (x_draw_composite_glyph_string_foreground):
5586 * term.c (encode_terminal_code):
5587 * composite.c (composition_update_it, get_composition_id):
5588 * xdisp.c (get_next_display_element)
5589 (fill_composite_glyph_string): Add comments about special meaning
5590 of TAB characters in a composition.
5592 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
5594 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
5595 This occurs when processing a multibyte format.
5596 Problem reported by Wolfgang Jenker.
5598 2011-09-15 Johan Bockgård <bojohan@gnu.org>
5600 * xdisp.c (try_cursor_movement): Only check for exact match if
5601 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
5603 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5605 Remove unused external symbols.
5606 * dispextern.h (calc_pixel_width_or_height): Remove decl.
5607 * xdisp.c (calc_pixel_width_or_height): Now static.
5608 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
5609 * indent.c (check_display_width):
5610 * w32term.c: Fix comment to match code.
5611 * xterm.c, xterm.h (x_catching_errors): Remove.
5613 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
5615 * xselect.c: Use signed conversions more consistently (Bug#9498).
5616 (selection_data_to_lisp_data): Assume incoming selection data are
5617 signed integers, not unsigned. This is to be consistent with
5618 outgoing selection data, which was modified to use signed integers
5619 in as part of the fix to Bug#9196 in response to Jan D.'s comment
5620 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
5621 expects long, not unsigned long.
5623 2011-09-14 Eli Zaretskii <eliz@gnu.org>
5625 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
5626 computation of loop end. Reported by Johan Bockgård
5629 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
5631 * frame.c (Fother_visible_frames_p): Function deleted.
5633 2011-09-12 Eli Zaretskii <eliz@gnu.org>
5635 * indent.c (compute_motion): Process display vector front to back
5636 rather than the other way around. (Bug#2496)
5638 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5640 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
5642 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
5644 * minibuf.c (Fread_from_minibuffer): Doc fix.
5646 2011-09-11 Eli Zaretskii <eliz@gnu.org>
5648 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
5649 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
5651 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
5653 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
5654 value for non-existent files.
5656 2011-09-11 Eli Zaretskii <eliz@gnu.org>
5658 * fileio.c (Finsert_file_contents): If the file cannot be opened,
5659 set its "size" to -1. This will set the modtime_size field of
5660 the corresponding buffer to -1, which is what
5661 verify-visited-file-modtime expects for files that do not exist.
5664 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
5666 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
5668 * lisp.h: ... from here. push_key_description is no longer
5669 defined in keyboard.c, so its declaration should not be in
5670 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
5671 logically belongs with push_key_description.
5673 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
5675 * buffer.h: Include <sys/types.h> instead of <time.h>.
5676 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
5677 Problem reported by Herbert J. Skuhra.
5679 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
5681 * xml.c (parse_region): Make the parsing work for
5682 non-comment-starting XML files again (bug#9144).
5684 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
5686 * image.c (gif_load): Fix calculation of bottom and right corner.
5689 2011-09-10 Eli Zaretskii <eliz@gnu.org>
5691 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
5692 redisplay in small windows.
5694 2011-09-09 Eli Zaretskii <eliz@gnu.org>
5696 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
5698 2011-09-08 Martin Rudalics <rudalics@gmx.at>
5700 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
5701 Operate on live windows only.
5703 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
5705 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
5707 2011-09-07 Eli Zaretskii <eliz@gnu.org>
5709 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
5710 only under bidi iteration.
5712 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
5714 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
5716 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
5718 isnan: Fix porting problem to Solaris 10 with bundled gcc.
5719 Without this fix, the command to link temacs failed due to an
5720 undefined symbol __builtin_isnan. This is because
5721 /usr/include/iso/math_c99.h #defines isnan(x) to
5722 __builtin_isnan(x), but the bundled gcc, which identifies itself
5723 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
5725 * floatfns.c (isnan): #undef, and then #define to a clone of
5727 (Fisnan): Always define, since it's always available now.
5728 (syms_of_floatfns): Always define isnan at the Lisp level.
5730 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
5732 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
5734 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
5736 * fileio.c: Fix bugs with large file offsets (Bug#9428).
5737 The previous code assumed that file offsets (off_t values) fit in
5738 EMACS_INT variables, which is not true on typical 32-bit hosts.
5739 The code messed up by falsely reporting buffer overflow in cases
5740 such as (insert-file-contents "big" nil 1 2) into an empty buffer
5741 when "big" contains more than 2**29 bytes, even though this
5742 inserts just one byte and does not overflow the buffer.
5743 (Finsert_file_contents): Store file offsets as off_t
5744 values, not as EMACS_INT values. Check for overflow when
5745 converting between EMACS_INT and off_t. When checking for
5746 buffer overflow or for overlap, take the offsets into account.
5747 Don't use EMACS_INT for small values where int suffices.
5748 When checking for overlap, fix a typo: ZV was used where
5749 ZV_BYTE was intended.
5750 (Fwrite_region): Don't assume off_t fits into 'long'.
5751 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
5753 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
5755 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
5757 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
5759 sprintf-related integer and memory overflow issues (Bug#9412).
5761 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
5762 (esprintf, exprintf, evxprintf): New functions.
5763 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
5764 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
5765 (modify_event_symbol): Do not assume that the length of
5766 name_alist_or_stem is safe to alloca and fits in int.
5767 (Fexecute_extended_command): Likewise for function name and binding.
5768 (Frecursion_depth): Wrap around reliably on integer overflow.
5769 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
5770 since some callers pass EMACS_INT values.
5771 (Fsingle_key_description): Don't crash if symbol name contains more
5772 than MAX_ALLOCA bytes.
5773 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
5774 (get_minibuffer): Arg is now EMACS_INT, not int.
5775 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
5776 (esprintf, exprintf, evxprintf): New decls.
5777 * window.h (command_loop_level, minibuf_level): Reflect API changes.
5779 * dbusbind.c (signature_cat): New function.
5780 (xd_signature, Fdbus_register_signal):
5781 Do not overrun buffer; instead, report string overflow.
5783 * dispnew.c (add_window_display_history): Don't overrun buffer.
5784 Truncate instead; this is OK since it's just a log.
5786 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
5787 even if the time zone offset is outlandishly large.
5788 Don't mishandle offset == INT_MIN.
5790 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
5791 when creating daemon; the previous buffer-overflow check was incorrect.
5793 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
5794 which has the guts of the old verror function.
5796 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
5797 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
5799 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
5800 (font_unparse_xlfd): Don't blindly alloca long strings.
5801 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
5802 fits in int, when using sprintf. Use single snprintf to count
5803 length of string rather than counting it via multiple sprintfs;
5804 that's simpler and more reliable.
5805 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
5806 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
5807 sprintf, in case result does not fit in int.
5809 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
5810 (fontset_from_font): Print it.
5812 * frame.c (tty_frame_count): Now printmax_t, not int.
5813 (make_terminal_frame, set_term_frame_name): Print it.
5814 (x_report_frame_params): In X, window IDs are unsigned long,
5815 not signed long, so print them as unsigned.
5816 (validate_x_resource_name): Check for implausibly long names,
5817 and don't assume name length fits in 'int'.
5818 (x_get_resource_string): Don't blindly alloca invocation name;
5819 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
5822 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
5823 (xg_check_special_colors, xg_set_geometry):
5824 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
5826 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
5827 Use esprintf, not sprintf, in case result does not fit in int.
5829 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
5830 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
5831 it as a large positive number.
5832 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
5833 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
5835 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
5836 in case result does not fit in int.
5838 * print.c (float_to_string): Detect width overflow more reliably.
5839 (print_object): Make sprintf buffer a bit bigger, to avoid potential
5840 buffer overrun. Don't assume list length fits in 'int'. Treat
5841 print length of 0 as 0, not as infinity; to be consistent with other
5842 uses of print length in this function. Don't overflow print length
5843 index. Don't assume hash table size fits in 'long', or that
5844 vectorlike size fits in 'unsigned long'.
5846 * process.c (make_process): Use printmax_t, not int, to format
5847 process-name gensyms.
5849 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
5851 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
5852 to avoid potential buffer overrun.
5854 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
5855 if X resource line is longer than 512 bytes.
5857 * xfns.c (x_window): Make sprintf buffer a bit bigger
5858 to avoid potential buffer overrun.
5860 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
5862 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
5864 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
5866 Integer overflow fixes for scrolling, etc.
5867 Without these, Emacs silently mishandles large integers sometimes.
5868 For example, "C-u 4294967297 M-x recenter" was treated as if
5869 it were "C-u 1 M-x recenter" on a typical 64-bit host.
5871 * xdisp.c (try_window_id): Check Emacs fixnum range before
5872 converting to 'int'.
5874 * window.c (window_scroll_line_based, Frecenter):
5875 Check that an Emacs fixnum is in range before assigning it to 'int'.
5876 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
5877 values converted from Emacs fixnums.
5878 (Frecenter): Don't wrap around a line count if it is out of 'int'
5879 range; instead, treat it as an extreme value.
5880 (Fset_window_configuration, compare_window_configurations):
5881 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
5883 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
5884 that can exceed INT_MAX. Check that EMACS_INT value is in range
5885 before assigning it to the (possibly-narrower) index.
5886 (match_limit): Don't assume that a fixnum can fit in 'int'.
5888 * print.c (print_object): Use ptrdiff_t, not int, for index that can
5891 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
5892 (Fvertical_motion): Don't wrap around LINES values that don't fit
5893 in 'int'. Instead, treat them as extreme values. This is good
5894 enough for windows, which can't have more than INT_MAX lines anyway.
5896 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
5898 * Require libxml/parser.h to avoid compilation warning.
5900 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
5902 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
5903 since this reportedly can destroy thread storage.
5905 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
5907 * syntax.c (find_defun_start): Update all cache variables if
5908 exiting early (Bug#9401).
5910 2011-08-30 Eli Zaretskii <eliz@gnu.org>
5912 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
5914 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
5915 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
5916 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
5918 * term.c (tty_append_glyph): New function.
5919 (produce_stretch_glyph): Static function and its prototype deleted.
5921 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
5924 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
5926 * image.c (parse_image_spec): Check for nonnegative, not for positive,
5927 when checking :margin (Bug#9390).
5928 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
5929 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
5930 so that the name doesn't mislead. All uses changed.
5932 2011-08-28 Johan Bockgård <bojohan@gnu.org>
5934 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
5937 2011-08-27 Eli Zaretskii <eliz@gnu.org>
5939 * xdisp.c (move_it_to): Don't bail out early when reaching
5940 position beyond to_charpos, if we are scanning backwards.
5941 (move_it_vertically_backward): When DY == 0, make sure we get to
5942 the first character in the line after the newline.
5944 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
5946 * ccl.c: Improve and simplify overflow checking (Bug#9196).
5947 (ccl_driver): Do not generate an out-of-range pointer.
5948 (Fccl_execute_on_string): Remove unnecessary check for
5949 integer overflow, noted by Stefan Monnier in
5950 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
5951 Remove a FIXME that didn't need fixing.
5952 Simplify the newly-introduced buffer reallocation code.
5954 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
5956 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
5958 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
5960 Integer and memory overflow issues (Bug#9196).
5962 * doc.c (get_doc_string): Rework so that
5963 get_doc_string_buffer_size is the actual buffer size, rather than
5964 being 1 less than the actual buffer size; this makes xpalloc more
5967 * image.c (x_allocate_bitmap_record, cache_image):
5968 * xselect.c (Fx_register_dnd_atom):
5969 Simplify previous changes by using xpalloc.
5971 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,

5975 (struct charset_sort_data.priority): Now ptrdiff_t.
5976 (charset_compare): Don't overflow if priorities differ greatly.
5977 (Fsort_charsets): Don't assume list length fits in int.
5978 Check for size-calculation overflow when allocating sort data.

5980 just under 64 KiB, to avoid problems with glibc malloc and mmap.
5982 * cmds.c (internal_self_insert): Check for size-calculation overflow.
5984 * composite.h (struct composition.glyph_len): Now int, not unsigned.
5985 The actual value is always <= INT_MAX, and leaving it unsigned made
5986 overflow checking harder.
5988 * dispextern.h (struct glyph_matrix.rows_allocated)
5989 (struct face_cache.size): Now ptrdiff_t, for convenience in use
5990 with xpalloc. The values are still always <= INT_MAX.

6000 (revalidate_region_cache, know_region_cache, region_cache_forward)
6001 (region_cache_backward, pp_cache):
6002 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6003 so that ptrdiff_t * can be passed to xpalloc.
6004 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6005 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

6020 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6022 Don't update size of array until after memory allocation succeeds,
6023 because xmalloc/xrealloc may not return.
6024 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6025 now that we have proper integer overflow checking.
6026 (record_overlay_string, overlay_strings): Catch overflows when
6027 calculating size of overlay_str_buf.
6029 * callproc.c (Fcall_process): Check for size overflow when
6030 calculating size of args2.

6032 Normally we prefer signed values, but sticking with ptrdiff_t would
6033 require adding more-complicated checks.
6035 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6036 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6037 Redo buffer-overflow calculations to avoid integer overflow.
6038 Add a FIXME comment where memory seems to be over-allocated.
6040 * character.c (Fstring): Check for size-calculation overflow.
6042 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6043 unnecessary integer overflow. Check for size overflow.

6075 Don't assume message length fits in int.
6076 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6078 * emacs.c (main): Do not reallocate argv, since there is a null at
6079 the end that can be overwritten, and this way there's no need to
6080 worry about size-calculation overflow.
6081 (sort_args): Check for size-calculation overflow.
6083 * eval.c (init_eval_once, grow_specpdl): Don't update size until
6085 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.

6088 (x_set_scroll_bar_width, x_figure_window_size):
6089 Check for integer overflow.
6090 (x_set_alpha): Do not assume XINT fits in int.
6092 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
6093 This is for the members text_lines, text_cols, total_lines, total_cols,
6094 where the system imposes an 'int' limit.
6096 * fringe.c (Fdefine_fringe_bitmap):
6097 Don't update size until alloc works.
6099 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
6100 (ftfont_shape_by_flt): Check for integer overflow in size calculations.

6103 Check for size-calculation overflow.
6104 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
6105 do, as we prefer signed integers.

6108 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
6109 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
6110 Use and return ptrdiff_t, not int.
6111 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
6112 * gtkutil.h: Change prototypes to match the above.
6114 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
6115 are duplicate now that they've been promoted to lisp.h.

6198 (Fx_change_window_property): Use ptrdiff_t, not int, to count
6199 sizes, since they can exceed INT_MAX in size. Check for size

6210 (X_LONG_MIN): New macros.
6211 Use them to make the following changes clearer.
6212 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
6213 This change doesn't affect the value now, but it may help remind
6214 future maintainers not to raise the value too much later.
6215 (SELECTION_QUANTUM): Remove, replacing with ...
6216 (selection_quantum): ... new function, which avoids overflow.
6218 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

6236 Don't store size until memory allocation succeeds.
6237 (x_get_window_property): Plug memory leak on memory exhaustion.
6238 Don't double-block input; malloc is safe here. Don't assume 2**34
6239 - 4 fits in unsigned long. Add an xassert to check
6240 XGetWindowProperty overflow. Be more careful about overflow
6241 calculations, and distinguish size from memory overflow better.
6242 (receive_incremental_selection): When tracing, don't assume
6243 unsigned int is less than INT_MAX.
6244 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

6247 in the range -65535 through -1 fit in an X unsigned short.
6248 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into

6250 to report problems with elements; the old code wasn't right anyway.
6251 (x_check_property_data): Check for int overflow; we cannot use
6252 a wider type due to X limits.

6285 * lisp.h (hash_lookup, hash_put):
6286 * minibuf.c (Ftest_completion):
6287 Use ptrdiff_t for hash table indexes, not int (which is too
6288 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

6327 (make_lispy_movement): Use same integer type in forward decl
6328 that is used in the definition.
6329 (read_key_sequence, keyremap_step):
6330 Change bufsize argument back to int, undoing my 2011-03-30 change.
6331 We prefer signed types, and int is wide enough here.
6332 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
6333 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
6334 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
6335 length, not size_t. Use ptrdiff_t for index, not int.
6336 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
6337 possibility of integer overflow.

6365 Prefer int to unsigned where either will do.
6366 (tiff_handler): New function, combining the cores of the
6367 old tiff_error_handler and tiff_warning_handler.

6370 that are common to both POSIX and native Microsoft.
6371 (tiff_error_handler, tiff_warning_handler): Use it.
6372 (tiff_load, gif_load, imagemagick_load_image):

6376 the integer types that MagickCropImage accepts. Don't assume
6377 Vimagemagick_render_type has a nonnegative value. Don't assume
6378 size_t fits in 'long'.
6379 (gs_load): Use printmax_t to print the widest integers possible.

6387 2011-08-25 Eli Zaretskii <eliz@gnu.org>
6389 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when

6393 (handle_single_display_spec): If the display spec is of the form
6394 `(space ...)', and specifies display in the text area, return 2

6415 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
6416 buffers, return left-to-right.
6417 (set_cursor_from_row): Consider candidate row a win if its glyph
6418 represents a newline and point is on that newline. Fixes cursor
6419 positioning on the newline at EOL of R2L text within L2R
6420 paragraph, and vice versa.
6421 (try_cursor_movement): Check continued rows, in addition to
6422 continuation rows. Fixes unwarranted scroll when point enters a
6423 continued line of R2L text within an L2R paragraph, or vice versa.
6424 (cursor_row_p): Consider the case of point being equal to
6425 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
6426 from the end of a short line to the beginning of a continued line
6427 of R2L text within L2R paragraph.
6428 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
6429 composed characters.
6431 * bidi.c (bidi_check_type): Use xassert.
6432 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
6435 2011-08-23 Eli Zaretskii <eliz@gnu.org>
6437 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of

6442 * nsfont.m (ns_otf_to_script): Fix typo.
6444 2011-08-22 Kenichi Handa <handa@m17n.org>
6446 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
6447 extra slot even if the purpose is char-code-property-table.
6449 2011-08-23 Eli Zaretskii <eliz@gnu.org>
6451 * xdisp.c (redisplay_window): When computing centering_position,
6452 account for the height of the header line. (Bug#8874)
6454 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
6455 instead of CHAR_TO_BYTE. Fixes a crash when a completion
6456 candidate is selected by the mouse, and that candidate has a
6457 composed character under the mouse.
6459 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
6460 coordinates reported by pos-visible-in-window-p for a composed
6461 character in column zero.
6463 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
6465 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
6467 2011-08-22 Eli Zaretskii <eliz@gnu.org>
6469 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
6470 consider it a hit if to_charpos is anywhere in the range of the
6471 composed buffer positions.
6473 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
6475 * image.c (gif_load): Don't assume that each subimage has the same
6476 dimensions as the base image. Handle disposal method that is
6477 "undefined" by the gif spec (Bug#9335).
6479 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
6481 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
6482 (Fcondition_case): Document `debug' symbol in error handler.
6484 2011-08-19 Eli Zaretskii <eliz@gnu.org>
6486 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
6487 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
6488 from an Org mode buffer to a Speedbar frame.
6490 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
6491 a composition, take its buffer position from IT->cmp_it.charpos.
6492 Fixes cursor positioning at the beginning of a line that begins
6493 with a composed character.
6495 2011-08-18 Eli Zaretskii <eliz@gnu.org>
6497 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
6498 character bidirectional type, use STRONG_L instead. Fixes crashes
6499 in a buffer produced by `describe-categories'.
6501 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
6502 members before the level stack, so they would be saved and
6503 restored when copying iterator state. Fixes incorrect reordering
6504 around TABs covered by display properties.
6506 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
6508 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
6510 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
6512 * eval.c (internal_condition_case, internal_condition_case_1)
6513 (internal_condition_case_2, internal_condition_case_n):
6514 Remove unnecessary aborts (Bug#9081).
6516 2011-08-17 Eli Zaretskii <eliz@gnu.org>
6518 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
6519 has no `load' handler, try opening the file locally. (Bug#9311)
6521 2011-08-16 Ken Brown <kbrown@cornell.edu>
6523 * gmalloc.c: Expand comment.
6525 2011-08-16 Eli Zaretskii <eliz@gnu.org>
6527 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
6528 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
6530 2011-08-16 Ken Brown <kbrown@cornell.edu>
6532 Fix memory allocation problems in Cygwin build (Bug#9273).
6534 * unexcw.c ( __malloc_initialized): Declare external variable.
6535 (fixup_executable): Force the dumped emacs to reinitialize malloc.
6537 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
6539 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
6541 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
6543 [CYGWIN] (special_realloc): New function.
6544 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
6545 requests to realloc storage in the static heap.

6549 * bidi.c (bidi_initialize): Remove unused local.
6551 2011-08-15 Eli Zaretskii <eliz@gnu.org>
6554 * biditype.h: Remove file.
6555 * makefile.w32-in ($(BLD)/bidi.$(O)):

6560 * chartab.c: Improve commentary for the uniprop_table API.
6562 * bidi.c (bidi_paragraph_init): Support zero value of
6563 bidi_ignore_explicit_marks_for_paragraph_level.
6564 (bidi_initialize): Use uniprop_table instead of including
6565 biditype.h and bidimirror.h.
6567 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
6568 coordinates of the iterator when restoring from ppos_it.
6571 2011-08-14 Kenichi Handa <handa@m17n.org>
6573 * process.c (create_process): Call setup_process_coding_systems
6574 after the pid of the process is set to -1 (Bug#8162).
6576 2011-08-14 Eli Zaretskii <eliz@gnu.org>
6578 * xdisp.c (move_it_in_display_line_to): Don't invoke
6579 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
6580 ppos_it. Fixes vertical cursor motion when line beginning is
6581 covered by an image. (Bug#9296)
6583 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
6585 * nsterm.h (ns_run_ascript): Declare.
6586 (NSAPP_DATA2_RUNASSCRIPT): Define.
6588 * nsfns.m (as_script, as_result, as_status): New static variables.
6589 (ns_run_ascript): New function.
6590 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
6591 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
6592 the event loop. Get status from as_status (Bug#7276).
6594 * nsterm.m (sendEvent): If event is NSApplicationDefined and
6595 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
6596 the event loop (Bug#7276).
6598 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
6600 * gnutls.c (QCgnutls_bootprop_priority)
6601 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
6602 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
6603 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
6604 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
6605 (QCgnutls_bootprop_verify_hostname_error)
6606 (QCgnutls_bootprop_callbacks_verify): Rename from
6607 Qgnutls_bootprop_..., all uses changed.

6615 * dispextern.h (Qframe_set_background_mode): Remove decl.
6617 * process.c (Fnetwork_interface_info): Declare local only if needed.
6619 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
6621 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
6622 (Fnetwork_interface_list): Allocate in increments of bytes instead
6623 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
6624 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
6626 (struct ifflag_def): notrailers is smart on OSX.
6627 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
6628 Get hardware address with getifaddrs if available.
6630 2011-08-12 Eli Zaretskii <eliz@gnu.org>
6632 * xdisp.c (iterate_out_of_display_property): xassert that
6633 IT->position is set to within IT->object's boundaries. Break from
6634 the loop as soon as EOB is reached; avoids infloops in redisplay
6635 when IT->position is set up wrongly due to some bug.
6636 Set IT->current to match the bidi iterator unconditionally.
6637 (push_display_prop): Allow GET_FROM_STRING as IT->method on
6638 entry. Force push_it to save on the stack the current
6639 buffer/string position, to be restored by pop_it. Fix flags in
6640 the iterator structure wrt the object coming from a display
6641 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
6642 properties. (Bug#9284)
6644 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
6646 * fontset.c (fontset_get_font_group): Add proper type checks.

6654 (dump_it) [LC_FUNCTION_STARTS]: Use it.
6656 2011-08-08 Eli Zaretskii <eliz@gnu.org>
6658 * xdisp.c (forward_to_next_line_start): Allow to use the
6659 no-display-properties-and-no-overlays under bidi display.
6660 Set disp_pos in the bidi iterator to avoid searches for display
6661 properties and overlays.
6663 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
6665 * editfns.c (Fset_time_zone_rule): Document relationship with the
6668 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
6669 the font entity extracted from the cache (Bug#8109).
6671 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
6673 * composite.c (autocmp_chars): Don't reset point. That is done by
6674 restore_point_unwind (Bug#5984).
6676 2011-08-07 Juri Linkov <juri@jurta.org>
6678 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
6679 to show the arg `TIME' instead of `TIMEVAL'.
6681 2011-08-06 Eli Zaretskii <eliz@gnu.org>
6683 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
6684 display property strides EOL and includes a newline, as in
6685 longlines-mode. (Bug#9254)
6686 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
6687 word-wrap under bidirectional display. (Bug#9224)
6689 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
6690 is non-zero, even if the data buffer is NULL. Fixes a crash in
6691 vertical-motion with longlines-mode. (Bug#9254)
6693 2011-08-05 Eli Zaretskii <eliz@gnu.org>
6695 * bidi.c <bidi_cache_total_alloc>: Now static.
6696 (bidi_initialize): Initialize bidi_cache_total_alloc.
6698 * xdisp.c (display_line): Release buffer allocated for shelved bidi
6701 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
6702 amount allocated this far in `bidi_cache_total_alloc'.
6703 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
6704 non-zero, only free the data buffer without restoring the cache
6705 contents. All callers changed.
6707 * dispextern.h (bidi_unshelve_cache): Update prototype.
6709 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
6710 (move_it_in_display_line, move_it_to)
6711 (move_it_vertically_backward, move_it_by_lines): Replace the call
6712 to xfree to an equivalent call to bidi_unshelve_cache.
6713 (move_it_in_display_line_to): Fix logic of returning
6714 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
6716 2011-08-05 Eli Zaretskii <eliz@gnu.org>
6718 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
6719 came from a string character with a `cursor' property. (Bug#9229)
6721 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
6723 * Makefile.in (LIB_PTHREAD): New variable.

6763 * xdisp.c: Remove one-slot cache of display string positions.
6764 (compute_display_string_pos): Accept an additional argument
6765 DISP_PROP_P; callers changed. Scan at most 5K characters forward
6766 for a display string or property. If found, set DISP_PROP_P
6769 * bidi.c (bidi_fetch_char): Accept an additional argument
6770 DISP_PROP_P, and pass it to compute_display_string_pos.
6771 Only handle text covered by a display string if DISP_PROP_P is returned
6772 non-zero. All callers of bidi_fetch_char changed.
6774 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

6792 BIDI_IT_PREV, and store into it the state of the bidi iterator had
6794 (reseat_at_next_visible_line_start): Use the bidi iterator state
6795 returned by forward_to_next_line_start to restore the state of
6796 it->bidi_it after backing up to previous newline. (Bug#9212)
6798 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
6800 * regex.c (re_comp): Protoize.
6801 (re_exec): Fix return type.

6806 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
6807 This is needed if max-image-size is a floating-point number.
6809 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
6811 * print.c (print_object): Print empty symbol as ##.
6813 * lread.c (read1): Read ## as empty symbol.

6822 contents (Bug#9176).
6823 (EmacsTooltip -init): Remove bezels and add shadows to

6856 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
6858 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
6859 Without this fix, if a signal arrives just after memory fills up,
6860 'malloc' might be invoked reentrantly.
6862 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
6863 In other words, assume that every image size is allowed, on non-X
6864 hosts. This assumption is probably wrong, but it lets Emacs compile.
6866 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
6868 * regex.c (re_iswctype): Convert return values to boolean.
6870 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>

6887 (bidi_cache_find_level_change, bidi_cache_ensure_space)
6888 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
6889 (bidi_find_other_level_edge):
6890 Use ptrdiff_t instead of EMACS_INT where either will do.
6891 This works better on 32-bit hosts configured --with-wide-int.
6892 (bidi_cache_ensure_space): Check for size-calculation overflow.
6893 Use % rather than repeated addition, for better worst-case speed.
6894 Don't set bidi_cache_size until after xrealloc returns, because it
6896 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
6897 (bidi_cache_ensure_space): Also check that the bidi cache size
6898 does not exceed that of the largest Lisp string or buffer. See Eli
6899 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
6901 * alloc.c (__malloc_size_t): Remove.
6902 All uses replaced by size_t. See Andreas Schwab's note
6903 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
6905 * image.c: Improve checking for integer overflow.
6906 (check_image_size): Assume that f is nonnull, since
6907 it is always nonnull in practice. This is one less thing to
6908 worry about when checking for integer overflow later.
6909 (x_check_image_size): New function, which checks for integer
6910 overflow issues inside X.
6911 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
6912 This removes the need for a memory_full check.
6913 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
6914 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
6915 (xbm_read_bitmap_data): Change locals back to 'int', since
6916 their values must fit in 'int'.
6917 (xpm_load_image, png_load, tiff_load):
6918 Invoke x_create_x_image_and_pixmap earlier,
6919 to avoid much needless work if the image is too large.
6920 (tiff_load): Treat overly large images as if
6921 x_create_x_image_and_pixmap failed, not as malloc failures.
6922 (gs_load): Use x_check_image_size.
6924 * gtkutil.c: Omit integer casts.
6925 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
6926 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
6928 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
6930 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
6931 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
6932 would wrongly return t on a 64-bit host.
6934 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
6935 The plain *_OVERFLOW macros run afoul of GCC bug 49705
6936 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
6937 and therefore cause GCC to emit a bogus diagnostic in some cases.
6939 * image.c: Integer signedness and overflow and related fixes.
6940 This is not an exhaustive set of fixes, but it's time to
6941 record what I've got.
6942 (lookup_pixel_color, check_image_size): Remove redundant decls.
6943 (check_image_size): Don't assume that arbitrary EMACS_INT values
6944 fit in 'int', or that arbitrary 'double' values fit in 'int'.
6945 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
6946 (tiff_load, imagemagick_load_image):
6947 Check for overflow in size calculations.
6948 (x_create_x_image_and_pixmap): Remove unnecessary test for
6949 xmalloc returning NULL; that can't happen.
6950 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
6951 (xpm_color_bucket): Use better integer hashing function.
6952 (xpm_cache_color): Don't possibly over-allocate memory.
6953 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
6954 (gif_memory_source):
6955 Use ptrdiff_t, not int or size_t, to record sizes.
6956 (png_load): Don't assume values greater than 2**31 fit in 'int'.
6957 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
6958 either works, as we prefer signed integers.
6959 (tiff_read_from_memory, tiff_write_from_memory):
6960 Return tsize_t, not size_t, since that's what the TIFF API wants.
6961 (tiff_read_from_memory): Don't fail simply because the read would
6962 go past EOF; instead, return a short read.
6963 (tiff_load): Omit no-longer-needed casts.
6964 (Fimagemagick_types): Don't assume size fits into 'int'.
6966 Improve hashing quality when configured --with-wide-int.
6967 * fns.c (hash_string): New function, taken from sxhash_string.
6968 Do not discard information about ASCII character case; this
6969 discarding is no longer needed.
6970 (sxhash-string): Use it. Change sig to match it. Caller changed.
6971 * lisp.h: Declare it.
6972 * lread.c (hash_string): Remove, since we now use fns.c's version.
6973 The fns.c version returns a wider integer if --with-wide-int is
6974 specified, so this should help the quality of the hashing a bit.
6976 * emacs.c: Integer overflow minor fix.
6977 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
6978 Define only if GNU_LINUX.
6979 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
6981 * dispnew.c: Integer signedness and overflow fixes.
6982 Remove unnecessary forward decls, that were a maintenance hassle.
6983 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
6985 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
6986 (scrolling_window): Use ptrdiff_t, not int, for byte count.
6987 (prepare_desired_row, line_draw_cost):
6988 Use int, not unsigned, where either works.
6989 (save_current_matrix, restore_current_matrix):
6990 Use ptrdiff_t, not size_t, where either works.
6991 (init_display): Check for overflow more accurately, and without
6992 relying on undefined behavior.
6994 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
6995 Remove, replacing with the new symbols in lisp.h. All uses changed.
6996 * fileio.c (make_temp_name):
6997 * filelock.c (lock_file_1, lock_file):
6998 * xdisp.c (message_dolog):
6999 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7000 Use pMd etc. instead.
7001 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7002 replacing the pWIDE etc. symbols removed from editfns.c.
7004 * keyboard.h (num_input_events): Now uintmax_t.
7005 This is (very slightly) less likely to mess up due to wraparound.
7008 * buffer.c: Integer signedness fixes.
7009 (alloc_buffer_text, enlarge_buffer_text):
7010 Use ptrdiff_t rather than size_t when either will do, as we prefer
7013 * alloc.c: Integer signedness and overflow fixes.
7014 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7015 (__malloc_size_t): Default to size_t, not to int.
7016 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7017 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7018 Prefer ptrdiff_t to size_t when either would do, as we prefer
7020 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7021 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7022 Now const. Initialize with values that are in range even if char
7024 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7025 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7026 These functions do the right thing with sizes > 2**32.
7027 (check_depth): Now ptrdiff_t, not int.
7028 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7029 Adjust to new way of storing sizes. Check for size overflow bugs
7031 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7032 slightly wrong anyway, as it missed one instance of
7033 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7034 (refill_memory_reserve): Omit needless cast to size_t.
7035 (mark_object_loop_halt): Mark as externally visible.
7037 * xselect.c: Integer signedness and overflow fixes.
7038 (Fx_register_dnd_atom, x_handle_dnd_message):
7039 Use ptrdiff_t, not size_t, since we prefer signed.
7040 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7041 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7042 x_dnd_atoms_size and x_dnd_atoms_length.
7044 * doprnt.c: Prefer signed to unsigned when either works.
7046 * doprnt.c (doprnt):
7048 * xdisp.c (vmessage):
7049 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7050 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7051 prefer signed arithmetic to avoid comparison confusion.
7052 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7053 but is a bit tricky.
7055 Assume freestanding C89 headers, string.h, stdlib.h.
7056 * data.c, doprnt.c, floatfns.c, print.c:
7057 Include float.h unconditionally.
7058 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7059 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7060 * regex.c: Likewise for stddef.h, string.h.
7061 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7062 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7063 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7064 (STDC_HEADERS): Remove obsolete defines.
7065 * sysdep.c: Include limits.h unconditionally.
7067 Assume support for memcmp, memcpy, memmove, memset.
7068 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7069 * regex.c (memcmp, memcpy):
7070 Remove; we assume C89 now.
7072 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7073 (__malloc_safe_bcopy): Remove; no longer needed.
7075 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7076 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7077 well either way, and we prefer signed to unsigned.
7079 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
7081 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
7082 closes the connection while we're reading (bug#9182).
7084 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
7086 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
7087 are specified (Bug#9168).
7089 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
7091 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
7092 Found by GCC static checking and --with-wide-int on a 32-bit host.
7094 2011-07-25 Eli Zaretskii <eliz@gnu.org>
7096 * xdisp.c (compute_display_string_pos): Fix logic of caching
7097 previous display string position. Initialize cached_prev_pos to
7098 -1. Fixes slow-down at the beginning of a buffer.
7100 2011-07-24 Eli Zaretskii <eliz@gnu.org>
7102 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
7103 for attrs[LFACE_FONTSET_INDEX].
7105 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
7107 * xml.c (parse_region): Remove unused local
7108 that was recently introduced.
7110 2011-07-23 Eli Zaretskii <eliz@gnu.org>
7112 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
7113 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
7115 * xdisp.c (move_it_in_display_line_to): Record the best matching
7116 position for TO_CHARPOS while scanning the line, and restore it on
7117 exit if none of the characters scanned was an exact match.
7118 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
7119 when exact match is impossible due to invisible text, and the
7120 lines are truncated.
7122 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
7124 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
7127 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7129 Fix a significant slow-down of cursor motion with C-n, C-p,
7130 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
7131 auto-repeat under bidi redisplay in fontified buffers.
7132 * xdisp.c (compute_stop_pos_backwards): New function.
7133 (next_element_from_buffer): Call compute_stop_pos_backwards to
7134 find a suitable prev_stop when we find ourselves before
7136 (reseat): Don't look for prev_stop, as that could mean a very long
7138 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
7139 <cached_disp_overlay_modiff>: Cache for last found display string
7141 (compute_display_string_pos): Return the cached position if asked
7142 about the same buffer in the same area of character positions, and
7143 the buffer wasn't changed since the time the display string
7144 position was cached.
7146 2011-07-22 Eli Zaretskii <eliz@gnu.org>
7148 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
7149 is an integer, which is important for empty lines. (Bug#9149)
7151 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
7153 * frame.c (Fmodify_frame_parameters): In tty case, update the
7154 default face if necessary (Bug#4238).
7156 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
7158 * editfns.c (Fstring_to_char): No need to explain what a character
7159 is in the docstring (Bug#6576).
7161 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7163 * xml.c (parse_region): Make sure we always return a tree.
7165 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
7167 * xml.c (parse_region): If a document contains only comments,
7170 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
7172 * xml.c (make_dom): Return comments, too.
7174 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
7177 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
7178 and the surrounding thread.
7179 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
7180 rather than fgets, and retry after EINTR. Otherwise, 'emacs
7181 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
7183 * s/openbsd.h (BROKEN_SIGIO): Define.
7184 * unexelf.c (unexec) [__OpenBSD__]:
7185 Don't update the .mdebug section of the Alpha COFF symbol table.
7187 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7189 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
7192 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
7194 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
7195 This fixes some race conditions on the permissions of any newly
7198 * alloc.c (valid_pointer_p): Use pipe, not open.
7199 This fixes some permissions issues when debugging.
7201 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
7202 If fchown fails to set both uid and gid, try to set just gid,
7203 as that is sometimes allowed. Adjust the file's mode to eliminate
7204 setuid or setgid bits that are inappropriate if fchown fails.
7206 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
7208 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
7209 to compare Lisp_Objects.
7210 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
7211 global_gnutls_log_level, don't mistake it for a Lisp_Object.
7212 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
7214 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
7216 * lread.c (read_integer): Unread even EOF character.
7217 (read1): Likewise. Properly record start position of symbol.
7219 * lread.c (read1): Read `#:' as empty uninterned symbol if no
7220 symbol character follows.
7222 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
7224 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
7225 This works around a problem with the previous change to Fcopy_file.
7226 Recent glibc declares fchown with __attribute__((warn_unused_result)),
7227 and without this change, GCC might complain about discarding
7228 fchown's return value.
7230 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
7232 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
7234 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
7236 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
7238 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
7240 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
7241 it's used from the C level.
7243 * process.c: Use the same condition for POLL_FOR_INPUT in both
7244 keyboard.c and process.c (bug#1858).
7246 2011-07-09 Lawrence Mitchell <wence@gmx.li>
7248 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
7249 (Fgnutls_boot): Use it.
7251 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
7253 * doc.c (Fsubstitute_command_keys): Revert last change.
7255 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
7257 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
7258 quotes the next character, and doesn't affect other longer
7259 sequences (bug#8935).
7261 * lread.c (syms_of_lread): Clarify that is isn't only
7262 `eval-buffer' and `eval-defun' that's affected by
7263 `lexical-binding' (bug#8460).
7265 2011-07-15 Eli Zaretskii <eliz@gnu.org>
7267 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
7268 bidi redisplay when a line includes both an image and is truncated.
7270 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
7272 Fix minor problems found by static checking.
7273 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
7274 (elsz): Now a signed constant, not a size_t var. We prefer signed
7275 types to unsigned, to avoid integer comparison confusion. Without
7276 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
7277 "cannot optimize loop, the loop counter may overflow", a symptom
7279 * indent.c (Fvertical_motion): Mark locals as initialized.
7280 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
7282 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
7284 * search.c (Fre_search_backward): Mention `case-fold-search' in
7285 all the re_search_* functions (bug#8138).
7287 * keyboard.c (Fopen_dribble_file): Document when the file is
7290 2011-07-14 Eli Zaretskii <eliz@gnu.org>
7292 * bidi.c (bidi_dump_cached_states): Fix format of displaying
7295 Support bidi reordering of display and overlay strings.
7296 * xdisp.c (compute_display_string_pos)
7297 (compute_display_string_end): Accept additional argument STRING.
7298 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
7299 (reseat_to_string): Initialize bidi_it->string.s and
7300 bidi_it->string.schars.
7301 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
7302 NULL (avoids a crash in bidi_paragraph_init).
7303 Initialize itb.string.lstring.
7304 (init_iterator): Call bidi_init_it only of a valid
7305 buffer position was specified. Initialize paragraph_embedding to
7307 (reseat_to_string): Initialize the bidi iterator.
7308 (display_string): If we need to ignore text properties of
7309 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
7310 original value of -1 will not work with bidi.)
7311 (compute_display_string_pos): First arg is now struct
7312 `text_pos *'; all callers changed. Support display properties on
7314 (compute_display_string_end): Support display properties on Lisp
7316 (init_iterator, reseat_1, reseat_to_string): Initialize the
7317 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
7318 when iterating on a string not from display properties).
7319 (compute_display_string_pos, compute_display_string_end):
7320 Fix calculation of the object to scan. Fixes an error when using
7322 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
7323 base_level_stop; instead, set base_level_stop to BEGV.
7324 Fixes crashes in vertical-motion.
7325 (next_element_from_buffer): Improve commentary for when
7326 the iterator is before prev_stop.
7327 (init_iterator): Initialize bidi_p from the default value of
7328 bidi-display-reordering, not from buffer-local value. Use the
7329 buffer-local value only if initializing for buffer iteration.
7330 (handle_invisible_prop): Support invisible properties on strings
7331 that are being bidi-reordered.
7332 (set_iterator_to_next): Support bidi reordering of C strings and
7334 (next_element_from_string): Support bidi reordering of Lisp
7336 (handle_stop_backwards): Support Lisp strings as well.
7337 (display_string): Support display of R2L glyph rows.
7338 Use IT_STRING_CHARPOS when displaying from a Lisp string.
7339 (init_iterator): Don't initialize it->bidi_p for strings
7341 (reseat_to_string): Initialize it->bidi_p for strings here.
7342 (next_element_from_string, next_element_from_c_string)
7343 (next_element_from_buffer): Add xassert's for correspondence
7344 between IT's object being iterated and it->bidi_it.string
7346 (face_before_or_after_it_pos): Support bidi iteration.
7347 (next_element_from_c_string): Handle the case of the first string
7348 character that is not the first one in the visual order.
7349 (get_visually_first_element): New function, refactored from common
7350 parts of next_element_from_buffer, next_element_from_string, and
7351 next_element_from_c_string.
7352 (tool_bar_lines_needed, redisplay_tool_bar)
7353 (display_menu_bar): Force left-to-right direction. Add a FIXME
7354 comment for making that be controlled by a user option.
7355 (push_it, pop_it): Save and restore the state of the
7356 bidi iterator. Save and restore the bidi_p flag.
7357 (pop_it): Iterate out of display property for string iteration as
7359 (iterate_out_of_display_property): Support iteration over strings.
7360 (handle_single_display_spec): Set up it->bidi_it for iteration
7361 over a display string, and call bidi_init_it.
7362 (handle_single_display_spec, next_overlay_string)
7363 (get_overlay_strings_1, push_display_prop): Set up the bidi

7845 Random fixes. E.g., (random) never returned negative values.
7846 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
7847 subseconds part to the entropy, as that's a bit more random.
7848 Prefer signed to unsigned, since the signedness doesn't matter and
7849 in general we prefer signed. When given a limit, use a
7850 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
7851 latter isn't right if USE_2_TAGS_FOR_INTS.
7852 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
7853 not 0..VALMASK. Don't discard "excess" bits that random () returns.
7855 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
7857 * textprop.c (text_property_stickiness):

7863 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
7865 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
7866 This is more efficient than Ffile_directory_p and avoids a minor race.
7868 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
7870 * buffer.c (Foverlay_put): Say what the return value is
7873 * fileio.c (barf_or_query_if_file_exists): Check first if the file
7874 is a directory before asking whether to use the file name
7876 (barf_or_query_if_file_exists): Make the "File is a directory"
7877 error be more correct.
7879 * fns.c (Frequire): Remove the mention of the .gz files, since
7880 that's installation-specific, but keep the mention of
7881 `get-load-suffixes'.
7883 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
7885 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

7896 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
7897 Also (re)move comments that are misplaced or no longer relevant.
7899 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>

7993 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
7996 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
7998 * eval.c (struct backtrace): Simplify and port the data structure.
7999 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8000 signed bit field, as this assumption is not portable and it makes
8001 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8002 "char debug_on_exit : 1" as this is not portable either; instead,
8003 use the portable "unsigned int debug_on_exit : 1". Remove unused
8004 member evalargs. Remove obsolete comments about cc bombing out.
8006 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

8168 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
8170 Integer and buffer overflow fixes (Bug#8873).
8172 * print.c (printchar, strout): Check for string overflow.
8173 (PRINTPREPARE, printchar, strout):
8174 Don't set size unless allocation succeeds.
8176 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,

8194 (read1): Check for integer overflow in radices, and in
8195 read-circle numbers.
8196 (read_escape): Avoid int overflow.
8197 (Fload, openp, read_buffer_size, read1)
8198 (substitute_object_recurse, read_vector, read_list, map_obarray):

8219 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8221 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
8222 The following patches are for when GLYPH_DEBUG && !XASSERT.
8223 * dispextern.h (trace_redisplay_p, dump_glyph_string):
8224 * dispnew.c (flush_stdout):
8225 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
8226 Mark as externally visible.
8227 * dispnew.c (check_window_matrix_pointers): Now static.
8228 * dispnew.c (window_to_frame_vpos):
8229 * xfns.c (unwind_create_frame):
8230 * xterm.c (x_check_font): Remove unused local.
8231 * scroll.c (CHECK_BOUNDS):
8232 * xfaces.c (cache_fache): Rename local to avoid shadowing.
8233 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
8234 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
8235 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
8236 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
8238 (debug_method_add): Use va_list and vsprintf rather than relying
8239 on undefined behavior with wrong number of arguments.
8240 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
8241 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
8242 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
8243 since we're not interested in debugging glyphs with old libraries.
8244 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
8245 GCC 4.6.0's static checking.
8247 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
8249 Integer overflow and signedness fixes (Bug#8873).

8273 * editfns.c (overlays_around, get_pos_property):
8274 * textprop.c (get_char_property_and_overlay):
8275 * xdisp.c (next_overlay_change, note_mouse_highlight):
8276 * xfaces.c (face_at_buffer_position):
8277 * buffer.c (OVERLAY_COUNT_MAX): New macro.
8278 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
8279 (Fnext_overlay_change, Fprevious_overlay_change)
8280 (mouse_face_overlay_overlaps, Foverlays_in):
8281 Use ptrdiff_t, not int, for sizes.
8282 (overlays_at, overlays_in): Check for size-calculation overflow.
8284 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
8286 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
8287 (x_session_initialize): Do not assume string length fits in int.
8289 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
8290 This is unlikely, but can occur if DPI is outlandish.
8292 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
8293 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8295 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
8296 * xrdb.c (magic_file_p, search_magic_path):
8297 Omit last arg SUFFIX; it was always 0. All callers changed.
8298 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
8300 * xfont.c (xfont_match): Avoid need for strlen.
8302 * xfns.c: Don't assume strlen fits in int.
8303 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
8305 * xdisp.c (message_log_check_duplicate): Return intmax_t,
8306 not unsigned long, as we prefer signed integers. All callers changed.
8307 Detect integer overflow in repeat count.
8308 (message_dolog): Don't assume print length fits in 39 bytes.
8309 (display_mode_element): Don't assume strlen fits in int.
8311 * termcap.c: Don't assume sizes fit in int and never overflow.
8312 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
8313 (gobble_line): Check for size-calculation overflow.
8315 * minibuf.c (Fread_buffer):
8316 * lread.c (intern, intern_c_string):
8317 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
8318 Don't assume string length fits in int.
8320 * keyboard.c (parse_tool_bar_item):
8321 * gtkutil.c (style_changed_cb): Avoid need for strlen.
8323 * font.c: Don't assume string length fits in int.
8324 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
8325 Use ptrdiff_t, not int.
8326 (font_intern_prop): Don't assume string length fits in int.
8327 Don't assume integer property fits in fixnum.
8328 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
8330 * filelock.c: Fix some buffer overrun and integer overflow issues.
8331 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
8332 Reformulate so as not to need the command string.
8333 Invoke gzip -cd rather than gunzip, as it's more portable.
8334 (lock_info_type, lock_file_1, lock_file):
8335 Don't assume pid_t and time_t fit in unsigned long.
8336 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
8337 (current_lock_owner): Prefer signed type for sizes.
8338 Use memcpy, not strncpy, where memcpy is what is really wanted.
8339 Don't assume (via atoi) that time_t and pid_t fit in int.
8340 Check for time_t and/or pid_t out of range, e.g., via a network share.
8341 Don't alloca where an auto var works fine.
8343 * fileio.c: Fix some integer overflow issues.
8344 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
8345 Don't assume string length fits in int.
8346 (directory_file_name): Don't assume string length fits in long.
8347 (make_temp_name): Don't assume pid fits in int, or that its print
8348 length is less than 20.
8350 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
8352 * coding.c (make_subsidiaries): Don't assume string length fits in int.
8354 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
8356 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
8357 We prefer signed integers, even for size calculations.
8359 * emacs.c: Don't assume string length fits in 'int'.
8360 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
8361 (main): Don't invoke strlen when not needed.
8363 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
8364 (XD_DEBUG_MESSAGE): Don't waste a byte.
8366 * callproc.c (getenv_internal_1, getenv_internal)
8368 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
8370 * lread.c (invalid_syntax): Omit length argument.
8371 All uses changed. This doesn't fix a bug, but it simplifies the
8372 code away from its former Hollerith-constant appearance, and it's
8373 one less 'int' to worry about when looking at integer-overflow issues.
8374 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
8376 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
8377 This didn't break anything, but it didn't help either.
8378 It's confusing to put a bogus integer in a place where the actual
8379 value does not matter.
8380 (LIST_END_P): Remove unused macro and its bogus comment.
8381 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
8383 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
8384 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
8386 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
8387 We prefer signed types, and the value cannot exceed the EMACS_INT
8388 range anyway (because otherwise the length would not be representable).
8389 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
8390 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
8391 This avoids a GCC warning when WIDE_EMACS_INT.
8393 * indent.c (sane_tab_width): New function.
8394 (current_column, scan_for_column, Findent_to, position_indentation)
8395 (compute_motion): Use it. This is just for clarity.
8396 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
8398 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
8400 * lisp.h (lint_assume): New macro.
8401 * composite.c (composition_gstring_put_cache):
8402 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
8404 * editfns.c, insdel.c:
8405 Omit unnecessary forward decls, to simplify future changes.
8407 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
8409 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
8411 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
8412 Use much-faster test for byte-length change.
8413 Don't assume string byte-length fits in 'int'.
8414 Check that character arg fits in 'int'.
8415 (mapcar1): Declare byte as byte, for clarity.
8417 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
8419 * fns.c (concat): Catch string overflow earlier.
8420 Do not rely on integer wraparound.
8422 * dispextern.h (struct it.overlay_strings_charpos)
8423 (struct it.selective): Now EMACS_INT, not int.
8424 * xdisp.c (forward_to_next_line_start)
8425 (back_to_previous_visible_line_start)
8426 (reseat_at_next_visible_line_start, next_element_from_buffer):
8427 Don't arbitrarily truncate the value of 'selective' to int.
8429 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
8431 * composite.c: Don't truncate sizes to 'int'.
8432 (composition_gstring_p, composition_reseat_it)
8433 (composition_adjust_point): Use EMACS_INT, not int.
8434 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
8435 not EMACS_UINT, for indexes.
8437 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
8439 * buffer.c: Include <verify.h>.
8440 (struct sortvec.priority, struct sortstr.priority):
8441 Now EMACS_INT, not int.
8442 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
8443 (struct sortstr.size, record_overlay_string)
8444 (struct sortstrlist.size, struct sortlist.used):
8445 Don't truncate size to int.
8446 (record_overlay_string): Check for size-calculation overflow.
8447 (init_buffer_once): Check at compile-time, not run-time.
8449 2011-06-22 Jim Meyering <meyering@redhat.com>
8451 Don't leak an XBM-image-sized buffer
8452 * image.c (xbm_load): Free the image buffer after using it.
8454 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
8457 * composite.c (find_automatic_composition): Omit needless 'return 0;'
8458 that Sun C diagnosed.
8459 * fns.c (secure_hash): Fix pointer signedness issue.
8460 * intervals.c (static_offset_intervals): New function.
8461 (offset_intervals): Use it.
8463 2011-06-21 Leo Liu <sdl.web@gmail.com>
8466 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
8469 * fns.c (secure_hash): Rename from crypto_hash_function and change
8470 the first arg to accept symbols.
8471 (Fsecure_hash): New primitive.
8472 (syms_of_fns): New symbols.
8474 2011-06-20 Deniz Dogan <deniz@dogan.se>
8476 * process.c (Fset_process_buffer): Clarify return value in
8479 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
8481 * dispnew.c (add_window_display_history): Use BVAR.
8483 * xdisp.c (debug_method_add): Use BVAR.
8484 (check_window_end, dump_glyph_matrix, dump_glyph)
8485 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
8487 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
8490 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
8491 check till after the cache is created in init_frame_faces.
8493 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
8495 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
8497 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
8499 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
8500 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
8501 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
8503 Improve buffer-overflow checking (Bug#8873).
8504 * fileio.c (Finsert_file_contents):
8505 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
8506 Remove the old (too-loose) buffer overflow checks.
8507 They weren't needed, since make_gap checks for buffer overflow.
8508 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
8509 The old code merely checked for Emacs fixnum overflow, and relied
8510 on undefined (wraparound) behavior. The new code avoids undefined
8511 behavior, and also checks for ptrdiff_t and/or size_t overflow.
8513 * editfns.c (Finsert_char): Don't dump core with very negative counts.
8514 Tune. Don't use wider integers than needed. Don't use alloca.
8515 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
8517 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
8519 * insdel.c, lisp.h (buffer_overflow): New function.
8520 (insert_from_buffer_1, replace_range, replace_range_2):
8521 * insdel.c (make_gap_larger):
8522 * editfns.c (Finsert_char):
8523 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
8525 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
8527 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
8529 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
8531 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
8532 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
8534 * fileio.c: Don't assume EMACS_INT fits in off_t.
8535 (emacs_lseek): New static function.
8536 (Finsert_file_contents, Fwrite_region): Use it.
8537 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
8539 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
8541 * fns.c: Don't overflow int when computing a list length.
8542 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
8543 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
8544 truncation on 64-bit hosts. Check for QUIT every
8545 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
8546 faster and is responsive enough.
8547 (Flength): Report an error instead of overflowing an integer.
8548 (Fsafe_length): Return a float if the value is not representable
8549 as a fixnum. This shouldn't happen except in contrived situations.
8550 (Fnthcdr, Fsort): Don't assume list length fits in int.
8551 (Fcopy_sequence): Don't assume vector length fits in int.
8553 * alloc.c: Check that resized vectors' lengths fit in fixnums.
8554 (header_size, word_size): New constants.
8555 (allocate_vectorlike): Don't check size overflow here.
8556 (allocate_vector): Check it here instead, since this is the only
8557 caller of allocate_vectorlike that could cause overflow.
8558 Check that the new vector's length is representable as a fixnum.
8560 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
8561 The previous code was bogus. For example, next_almost_prime (32)
8562 returned 39, which is undesirable as it is a multiple of 3; and
8563 next_almost_prime (24) returned 25, which is a multiple of 5 so
8564 why was the code bothering to check for multiples of 7?
8566 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
8568 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
8570 Variadic C functions now count arguments with ptrdiff_t.
8571 This partly undoes my 2011-03-30 change, which replaced int with size_t.
8572 Back then I didn't know that the Emacs coding style prefers signed int.
8573 Also, in the meantime I found a few more instances where arguments
8574 were being counted with int, which may truncate counts on 64-bit
8575 machines, or EMACS_INT, which may be unnecessarily wide.
8576 * lisp.h (struct Lisp_Subr.function.aMANY)
8577 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
8578 Arg counts are now ptrdiff_t, not size_t.
8579 All variadic functions and their callers changed accordingly.
8580 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
8581 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
8582 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
8583 * callint.c (Fcall_interactively): Check arg count for overflow,
8584 to avoid potential buffer overrun. Use signed char, not 'int',
8585 for 'varies' array, so that we needn't bother to check its size
8586 calculation for overflow.
8587 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
8588 * eval.c (apply_lambda):
8589 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
8590 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
8591 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
8593 * callint.c (Fcall_interactively): Don't use index var as event count.
8595 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
8596 * mem-limits.h (SIZE): Remove; no longer used.
8598 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
8600 Remove unnecessary casts.
8601 * xterm.c (x_term_init):
8602 * xfns.c (x_set_border_pixel):
8603 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
8604 These aren't needed now that we assume ANSI C.
8606 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
8607 It's more likely to cause problems (due to unsigned overflow)
8610 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
8612 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
8614 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
8616 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
8618 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
8620 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
8622 GLYPH_CODE_FACE returns EMACS_INT, not int.
8623 * dispextern.h (merge_faces):
8624 * xfaces.c (merge_faces):
8625 * xdisp.c (get_next_display_element, next_element_from_display_vector):
8626 Don't assume EMACS_INT fits in int.
8628 * character.h (CHAR_VALID_P): Remove unused parameter.
8629 * fontset.c, lisp.h, xdisp.c: All uses changed.
8631 * editfns.c (Ftranslate_region_internal): Omit redundant test.
8633 * fns.c (concat): Minor tuning based on overflow analysis.
8634 This doesn't fix any bugs. Use int to hold character, instead
8635 of constantly refetching from Emacs object. Use XFASTINT, not
8636 XINT, for value known to be a character. Don't bother comparing
8637 a single byte to 0400, as it's always less.
8639 * floatfns.c (Fexpt):
8640 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
8642 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
8645 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
8647 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
8648 Without this fix, on a 64-bit host (aset S 0 4294967386) would
8649 incorrectly succeed when S was a string, because 4294967386 was
8650 truncated before it was used.
8652 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
8653 Otherwise, an out-of-range integer could cause undefined behavior
8656 * composite.c: Use int, not EMACS_INT, for characters.
8657 (fill_gstring_body, composition_compute_stop_pos): Use int, not
8658 EMACS_INT, for values that are known to be in character range.
8659 This doesn't fix any bugs but is the usual style inside Emacs and
8660 may generate better code on 32-bit machines.
8662 Make sure a 64-bit char is never passed to ENCODE_CHAR.
8663 This is for reasons similar to the recent CHAR_STRING fix.
8664 * charset.c (Fencode_char): Check that character arg is actually
8665 a character. Pass an int to ENCODE_CHAR.
8666 * charset.h (ENCODE_CHAR): Verify that the character argument is no
8667 wider than 'int', as a compile-time check to prevent future regressions
8670 * character.c (char_string): Remove unnecessary casts.
8672 Make sure a 64-bit char is never passed to CHAR_STRING.
8673 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
8674 by silently ignoring the top 32 bits, allowing some values
8675 that were far too large to be valid characters.
8676 * character.h: Include <verify.h>.
8677 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
8678 arguments are no wider than unsigned, as a compile-time check
8679 to prevent future regressions in this area.
8681 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
8682 (Fsubst_char_in_region):
8684 * xdisp.c (decode_mode_spec_coding):
8685 Adjust to CHAR_STRING's new requirement.
8686 * editfns.c (Finsert_char, Fsubst_char_in_region):
8687 * fns.c (concat): Check that character args are actually
8688 characters. Without this test, these functions did the wrong
8689 thing with wildly out-of-range values on 64-bit hosts.
8691 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
8692 These casts should not be needed on 32-bit hosts, either.
8693 * keyboard.c (read_char):
8694 * lread.c (Fload): Remove casts to unsigned.
8696 * lisp.h (UNSIGNED_CMP): New macro.
8697 This fixes comparison bugs on 64-bit hosts.
8698 (ASCII_CHAR_P): Use it.
8699 * casefiddle.c (casify_object):
8700 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
8701 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
8702 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
8703 * dispextern.h (FACE_FROM_ID):
8704 * keyboard.c (read_char): Use UNSIGNED_CMP.
8706 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
8707 not to EMACS_INT, to avoid GCC warning.
8709 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
8711 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
8712 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
8713 isn't needed on 32-bit machines.
8715 * buffer.c (Fgenerate_new_buffer_name):
8716 Use EMACS_INT for count, not int.
8717 (advance_to_char_boundary): Return EMACS_INT, not int.
8719 * data.c (Qcompiled_function): Now static.
8721 * window.c (window_body_lines): Now static.
8723 * image.c (gif_load): Rename local to avoid shadowing.
8725 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
8726 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
8727 * alloc.c (make_save_value): Integer argument is now of type
8729 (mark_object): Use ptrdiff_t, not int.
8730 * lisp.h (pD): New macro.
8731 * print.c (print_object): Use it.
8733 * alloc.c: Use EMACS_INT, not int, to count objects.
8734 (total_conses, total_markers, total_symbols, total_vector_size)
8735 (total_free_conses, total_free_markers, total_free_symbols)

8763 (allocate_string_data): Check for string overflow. This catches
8764 some instances we weren't catching before. Also, it catches
8765 size_t overflow on (unusual) hosts where SIZE_MAX <= min
8766 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
8767 and ptrdiff_t and EMACS_INT are both 64 bits.

9191 Use STRING_BYTES_MAX, not MOST_POSITIVE_FIXNUM,
9192 since they may not be the same number.
9193 * editfns.c (Finsert_char):
9194 * fileio.c (Finsert_file_contents):
9195 Likewise for BUF_BYTES_MAX.
9197 * image.c: Use ptrdiff_t, not int, for sizes.
9198 (slurp_file): Switch from int to ptrdiff_t.
9200 (slurp_file): Check that file size fits in both size_t (for
9201 malloc) and ptrdiff_t (for sanity and safety).
9203 * fileio.c (Fverify_visited_file_modtime): Avoid time overflow
9204 if b->modtime has its maximal value.
9206 * dired.c (Ffile_attributes): Don't assume EMACS_INT has >32 bits.
9208 Don't assume time_t can fit into int.

9215 * charset.c (maybe_unify_char):
9216 * keyboard.c (read_char, reorder_modifiers):
9217 XINT -> XFASTINT, since the integer must be nonnegative.
9218 * ftfont.c (ftfont_spec_pattern):
9219 * keymap.c (access_keymap, silly_event_symbol_error):
9220 XUINT -> XFASTINT, since the integer must be nonnegative.
9221 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
9222 since it makes no difference and we prefer signed.
9223 * keyboard.c (record_char): Use XUINT when all the neighbors do.
9224 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

9235 (LARGE_REQUEST): Remove.
9236 (memory_full): Use SPARE_MEMORY rather than LARGE_REQUEST.
9238 2011-06-06 Martin Rudalics <rudalics@gmx.at>
9240 * lisp.h: Move EXFUNS for Fframe_root_window,
9241 Fframe_first_window and Fset_frame_selected_window to window.h.
9243 * window.h: Move EXFUNS for Fframe_root_window,
9244 Fframe_first_window and Fset_frame_selected_window here from

9265 or arbitrary window as argument. Update doc-strings.
9266 (Fminibuffer_window): Move up in code.
9267 (Fwindow_minibuffer_p): Move up in code and simplify.
9268 (Fset_frame_selected_window): Move here from frame.c.

9273 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
9275 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
9276 Do not assume that spare memory exists; that assumption is valid
9277 only if SYSTEM_MALLOC.
9278 (LARGE_REQUEST): New macro, so that the issue of large requests
9279 is separated from the issue of spare memory.
9281 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
9283 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

9302 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
9304 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

9316 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
9318 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
9320 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9322 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
9323 in the current matrix if keep_current_p is non-zero.

9327 * bidi.c (bidi_level_of_next_char): Fix last change.
9329 2011-06-03 Eli Zaretskii <eliz@gnu.org>
9331 Support bidi reordering of text covered by display properties.
9333 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
9334 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
9335 (bidi_cache_search, bidi_cache_iterator_state)
9336 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
9337 (bidi_level_of_next_char, bidi_move_to_visually_next):
9338 Support character positions inside a run of characters covered by a
9340 (bidi_paragraph_init, bidi_resolve_explicit_1)
9341 (bidi_level_of_next_char): Call bidi_fetch_char and
9342 bidi_fetch_char_advance instead of FETCH_CHAR and
9344 (bidi_init_it): Initialize new members.
9345 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
9347 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
9348 instead of using explicit *_CHAR codes.
9349 (bidi_resolve_explicit, bidi_resolve_weak):
9350 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
9351 bidirectional text is supported only in multibyte buffers.
9352 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
9353 it to initialize the frame_window_p member of struct bidi_it.
9354 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
9355 (bidi_resolve_explicit, bidi_resolve_weak)
9356 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
9357 bidi_it->nchars is non-positive.
9358 (bidi_level_of_next_char): Don't try to lookup the cache for the
9359 next/previous character if nothing is cached there yet, or if we
9360 were just reseat()'ed to a new position.
9362 * xdisp.c (set_cursor_from_row): Set start and stop points
9363 according to the row's direction when priming the loop that looks
9364 for the glyph on which to display cursor.
9365 (single_display_spec_intangible_p): Function deleted.
9366 (display_prop_intangible_p): Reimplement to call
9367 handle_display_spec instead of single_display_spec_intangible_p.
9368 Accept 3 additional arguments needed by handle_display_spec.
9369 This fixes incorrect cursor motion across display property with complex
9370 values: lists, `(when COND...)' forms, etc.
9371 (single_display_spec_string_p): Support property values that are
9372 lists with the argument STRING its top-level element.
9373 (display_prop_string_p): Fix the condition for processing a
9374 property that is a list to be consistent with handle_display_spec.
9375 (handle_display_spec): New function, refactored from the
9376 last portion of handle_display_prop.
9377 (compute_display_string_pos): Accept additional argument
9378 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
9379 value of a `display' property is a "replacing spec".
9380 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
9381 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
9382 the display property, but just return a value indicating whether
9383 the display property will replace the characters it covers.
9384 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
9385 frame_window_p members of struct bidi_it.
9386 (compute_display_string_pos, compute_display_string_end):
9388 (push_it): Accept second argument POSITION, where pop_it should
9389 jump to continue iteration.
9390 (reseat_1): Initialize bidi_it.disp_pos.
9392 * keyboard.c (adjust_point_for_property): Adjust the call to
9393 display_prop_intangible_p to its new signature.
9395 * dispextern.h (struct bidi_it): New member frame_window_p.
9396 (bidi_init_it): Update prototypes.
9397 (display_prop_intangible_p): Update prototype.
9398 (compute_display_string_pos, compute_display_string_end):
9400 (struct bidi_it): New members nchars and disp_pos. ch_len is now
9403 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
9405 Malloc failure behavior now depends on size of allocation.
9406 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
9407 * lisp.h: Change signatures accordingly.
9408 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
9409 All callers changed. (Bug#8762)
9411 * gnutls.c: Use Emacs's memory allocators.
9412 Without this change, the gnutls library would invoke malloc etc.
9413 directly, which causes problems on non-SYNC_INPUT hosts, and which
9414 runs afoul of improving memory_full behavior. (Bug#8761)
9415 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
9416 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
9417 xfree instead of the default malloc, realloc, free.
9418 (Fgnutls_boot): No need to check for memory allocation failure,
9419 since xmalloc does that for us.
9421 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
9422 * category.c (hash_get_category_set):
9423 * ccl.c (ccl_driver):
9424 * charset.c (Fdefine_charset_internal):

9435 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
9436 (Fsxhash, Fgethash, Fputhash, Fmaphash):
9437 * image.c (make_image, search_image_cache, lookup_image)
9438 (xpm_put_color_table_h):
9439 * lisp.h (struct Lisp_Hash_Table):
9440 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
9441 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
9442 for hashes and hash indexes, instead of 'unsigned' and 'int'.
9443 * alloc.c (allocate_vectorlike):
9444 Check for overflow in vector size calculations.
9445 * ccl.c (ccl_driver):
9446 Check for overflow when converting EMACS_INT to int.
9447 * fns.c, image.c: Remove unnecessary static decls that would otherwise
9448 need to be updated by these changes.
9449 * fns.c (make_hash_table, maybe_resize_hash_table):
9450 Check for integer overflow with large hash tables.
9451 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
9452 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
9453 (SXHASH_REDUCE): New macro.
9454 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
9455 Use it instead of discarding useful hash info with large hash values.
9456 (sxhash_float): New function.
9457 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
9458 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
9459 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
9460 Rewrite to use FIXNUM_BITS, as this simplifies things.
9461 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
9462 Adjust signatures to match updated version of code.
9463 (consing_since_gc): Now EMACS_INT, since a single hash table can
9464 use more than INT_MAX bytes.
9466 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
9468 Make it possible to build with GCC-4.6+ -O2 -flto.
9470 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
9472 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
9474 * minibuf.c (get_minibuffer, read_minibuf_unwind):
9475 Call minibuffer-inactive-mode.
9477 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
9479 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
9480 Update dependencies.
9482 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9484 * data.c (init_data): Remove code for UTS, this system is not
9487 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9489 Don't force ./temacs to start in terminal mode.
9491 * frame.c (make_initial_frame): Initialize faces in all cases, not
9492 only when CANNOT_DUMP is defined.
9493 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
9495 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9497 * dispnew.c (add_window_display_history): Use const for the string
9498 pointer. Remove declaration, not needed.
9500 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9502 Use 'inline', not 'INLINE'.
9503 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
9504 * alloc.c, fontset.c (INLINE): Remove.
9505 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
9506 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
9507 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
9508 * gmalloc.c (register_heapinfo): Use inline unconditionally.
9509 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
9511 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
9513 Make it possible to run ./temacs.
9515 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
9516 syms_of_callproc does the same thing. Remove test for
9517 "initialized", do it in the caller.
9518 * emacs.c (main): Avoid calling set_initial_environment when dumping.
9520 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
9522 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
9523 (read_minibuf): Use get_minibuffer.
9524 (syms_of_minibuf): Use DEFSYM.
9525 (Qmetadata): New var.
9526 * data.c (Qbuffer): Don't make it static.
9527 (syms_of_data): Use DEFSYM.
9529 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
9531 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
9532 (CCL_CODE_MIN): New macro.
9534 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
9536 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
9538 * eval.c (Qdebug): Now static.
9539 * lisp.h (Qdebug): Remove decl. This reverts a part of the
9540 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
9541 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
9543 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9545 * image.c: Various fixes to ImageMagick code comments.
9546 (Fimagemagick_types): Doc fix.
9548 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
9550 Minor fixes prompted by GCC 4.6.0 warnings.
9552 * xselect.c (converted_selections, conversion_fail_tag): Now static.
9554 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
9555 (x_clipboard_manager_save_all): Move extern decl to ...
9556 * xterm.h: ... here, so that it can be checked for consistency.
9558 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
9560 * xselect.c (x_clipboard_manager_save_frame)
9561 (x_clipboard_manager_save_all): New functions.
9562 (Fx_clipboard_manager_save): Lisp function deleted.
9564 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
9565 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
9567 * xterm.h: Update prototype.
9569 2011-05-28 William Xu <william.xwl@gmail.com>
9571 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
9574 2011-05-28 Jim Meyering <meyering@redhat.com>
9576 Avoid a sign-extension bug in crypto_hash_function.
9577 * fns.c (to_uchar): Define.
9578 (crypto_hash_function): Use it to convert some newly-signed
9579 variables to unsigned, to avoid sign-extension bugs. For example,
9580 without this change, (md5 "truc") would evaluate to
9581 45723a2aff78ff4fff7fff1114760e62 rather than the expected
9582 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
9583 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
9585 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9587 Integer overflow fixes.
9589 * dbusbind.c: Serial number integer overflow fixes.
9590 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
9591 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
9592 to hold a serial number that is too large for a fixnum.
9593 (Fdbus_method_return_internal, Fdbus_method_error_internal):
9594 Check for serial numbers out of range. Decode any serial number
9595 that was so large that it became a float. (Bug#8722)
9597 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
9598 (Fdbus_call_method, Fdbus_call_method_asynchronously):
9599 Use XFASTINT rather than XUINT when numbers are nonnegative.
9600 (xd_append_arg, Fdbus_method_return_internal):
9601 (Fdbus_method_error_internal): Likewise. Also, for unsigned
9602 arguments, check that Lisp number is nonnegative, rather than
9603 silently wrapping negative numbers around. (Bug#8722)
9604 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
9607 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
9609 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
9611 ccl: Add integer overflow checks.
9612 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
9613 (IN_INT_RANGE): New macros.
9614 (ccl_driver): Use them to check for integer overflow when
9615 decoding a CCL program. Many of the new checks are whether XINT (x)
9616 fits in int; it doesn't always, on 64-bit hosts. The new version
9617 doesn't catch all possible integer overflows, but it's an
9618 improvement. (Bug#8719)
9620 * alloc.c (make_event_array): Use XINT, not XUINT.
9621 There's no need for unsigned here.
9623 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
9624 This follows up to the 2011-05-06 change that substituted uintptr_t
9625 for EMACS_INT. This case wasn't caught back then.
9627 Rework Fformat to avoid integer overflow issues.
9628 * editfns.c: Include <float.h> unconditionally, as it's everywhere
9629 now (part of C89). Include <verify.h>.
9630 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
9631 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
9632 (Fformat): Avoid the prepass trying to compute sizes; it was only
9633 approximate and thus did not catch overflow reliably. Instead, walk
9634 through the format just once, formatting and computing sizes as we go,
9635 checking for integer overflow at every step, and allocating a larger
9636 buffer as needed. Keep track separately whether the format is
9637 multibyte. Keep only the most-recently calculated precision, rather
9638 than them all. Record whether each argument has been converted to
9639 string. Use EMACS_INT, not int, for byte and char and arg counts.
9640 Support field widths and precisions larger than INT_MAX. Avoid
9641 sprintf's undefined behavior with conversion specifications such as %#d
9642 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
9643 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
9644 formatting out-of-range floating point numbers with int
9647 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
9649 * data.c: Avoid integer truncation in expressions involving floats.
9650 * data.c: Include <intprops.h>.
9651 (arith_driver): When there's an integer overflow in an expression
9652 involving floating point, convert the integers to floating point
9653 so that the resulting value does not suffer from catastrophic
9654 integer truncation. For example, on a 64-bit host (* 4
9655 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
9656 Do not rely on undefined behavior after integer overflow.
9658 merge count_size_as_multibyte, parse_str_to_multibyte
9659 * character.c, character.h (count_size_as_multibyte):
9660 Rename from parse_str_to_multibyte; all uses changed.
9661 Check for integer overflow.
9662 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
9663 since it's now a duplicate of the other. This is more of
9664 a character than a buffer op, so better that it's in character.c.
9665 * fns.c, print.c: Adjust to above changes.
9667 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
9669 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
9671 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
9673 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9674 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
9675 (x_clipboard_manager_save): Now static.
9676 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
9678 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
9679 (crypto_hash_function): Now static.
9680 Fix pointer signedness problems. Avoid unnecessary initializations.
9682 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
9684 * termhooks.h (Vselection_alist): Make it terminal-local.
9686 * terminal.c (create_terminal): Initialize it.
9688 * xselect.c: Support for clipboard managers.
9689 (Vselection_alist): Move to termhooks.h as terminal-local var.
9690 (LOCAL_SELECTION): New macro.
9691 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
9692 (symbol_to_x_atom): Remove gratuitous arg.
9693 (x_handle_selection_request, lisp_data_to_selection_data)
9694 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
9695 (x_own_selection, x_get_local_selection, x_convert_selection):
9696 New arg, specifying work frame. Use terminal-local Vselection_alist.
9697 (some_frame_on_display): Delete unused function.
9698 (Fx_own_selection_internal, Fx_get_selection_internal)
9699 (Fx_disown_selection_internal, Fx_selection_owner_p)
9700 (Fx_selection_exists_p): New optional frame arg.
9701 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
9702 (x_handle_selection_clear): Don't treat other terminals with the
9703 same keyboard specially. Use the terminal-local Vselection_alist.
9704 (x_clear_frame_selections): Use Frun_hook_with_args.
9706 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
9708 * xterm.h: Add support for those atoms.
9710 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
9712 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
9713 (converted_selections, conversion_fail_tag): New global variables.
9714 (x_selection_request_lisp_error): Free the above.
9715 (x_get_local_selection): Remove unnecessary code.
9716 (x_reply_selection_request): Args changed; handle arbitrary array
9717 of converted selections stored in converted_selections.
9718 Separate the XChangeProperty and SelectionNotify steps.
9719 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
9720 (x_convert_selection): New function.
9721 (x_handle_selection_event): Simplify.
9722 (x_get_foreign_selection): Don't ignore incoming requests while
9723 waiting for an answer; this will fail when we implement
9724 SAVE_TARGETS, and seems unnecessary anyway.
9725 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
9726 (Vx_sent_selection_functions): Doc fix.
9728 2011-05-26 Leo Liu <sdl.web@gmail.com>
9730 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
9732 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9734 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
9736 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
9737 for fringe update if it has periodic bitmap.
9738 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
9739 and fringe_bitmap_periodic_p.
9741 * fringe.c (get_fringe_bitmap_data): New function.
9742 (draw_fringe_bitmap_1, update_window_fringes): Use it.
9743 (update_window_fringes): Record periodicity of fringe bitmap in glyph
9744 row. Mark glyph row for fringe update if periodicity changed.
9746 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
9747 for fringe update unless it has periodic bitmap.
9749 2011-05-25 Kenichi Handa <handa@m17n.org>
9751 * xdisp.c (get_next_display_element): Set correct it->face_id for
9752 a static composition.
9754 2011-05-24 Leo Liu <sdl.web@gmail.com>
9757 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
9759 * fns.c (crypto_hash_function, Fsha1): New function.
9760 (Fmd5): Use crypto_hash_function.
9761 (syms_of_fns): Add Ssha1.
9763 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
9765 * gnutls.c: Remove unused macros.
9766 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
9767 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
9768 Remove macros that are defined and never used.
9769 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
9771 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
9773 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
9774 (Fx_get_selection_internal): Minor cleanup.
9775 (Fx_own_selection_internal): Rename arguments for consistency with
9778 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
9780 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
9782 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
9784 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
9786 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9788 * dispnew.c (scrolling_window): Don't exclude the case that the
9789 last enabled row in the desired matrix touches the bottom boundary.
9791 2011-05-21 Glenn Morris <rgm@gnu.org>
9793 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
9794 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
9795 and add some more files.
9797 2011-05-20 Eli Zaretskii <eliz@gnu.org>
9799 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
9800 report_file_error introduced by the change from 2011-05-07.
9802 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
9804 * systime.h (Time): Define only if emacs is defined.
9805 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
9806 where the include path doesn't have X11/X.h by default. See
9807 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
9809 2011-05-20 Kenichi Handa <handa@m17n.org>
9811 * composite.c (find_automatic_composition): Fix previous change.
9813 2011-05-20 Glenn Morris <rgm@gnu.org>
9815 * lisp.mk: New file, split from Makefile.in.
9816 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
9817 (shortlisp): Remove.
9818 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
9820 2011-05-19 Glenn Morris <rgm@gnu.org>
9822 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
9823 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
9824 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
9825 (lisp): Set the order to that of loadup.el.
9826 (shortlisp): Make it a copy of $lisp.
9827 (SOME_MACHINE_LISP): Remove.
9828 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
9829 Use just $shortlisp, not $SOME_MACHINE_LISP too.
9831 2011-05-18 Kenichi Handa <handa@m17n.org>
9833 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
9834 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
9835 (find_automatic_composition): Mostly rewrite for efficiency.
9837 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
9839 * makefile.w32-in: Update dependencies.
9841 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
9843 * menu.c: Include limits.h (fixes the MS-Windows build broken by
9844 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
9846 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
9848 Fix some integer overflow issues, such as string length overflow.
9850 * insdel.c (count_size_as_multibyte): Check for string overflow.
9852 * character.c (lisp_string_width): Check for string overflow.
9853 Use EMACS_INT, not int, for string indexes and lengths; in
9854 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
9855 the resulting string length overflows an EMACS_INT; instead,
9856 report a string overflow if no precision given. When checking for
9857 precision exhaustion, use a check that cannot possibly have
9858 integer overflow. (Bug#8675)
9859 * character.h (lisp_string_width): Adjust to new signature.
9861 * alloc.c (string_overflow): New function.
9862 (Fmake_string): Use it. This doesn't change behavior, but saves
9863 a few bytes and will simplify future changes.
9864 * character.c (string_escape_byte8): Likewise.
9865 * lisp.h (string_overflow): New decl.
9867 Fixups, following up to the user-interface timestamp change.
9868 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
9869 for UI timestamps, instead of unsigned long.
9870 * msdos.c (mouse_get_pos): Likewise.
9871 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
9872 * w32gui.h (Time): Define by including "systime.h" rather than by
9873 declaring it ourselves. (Bug#8664)
9875 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
9876 * image.c (clear_image_cache): Likewise.
9878 * term.c (term_mouse_position): Don't assume time_t wraparound.
9880 Be more systematic about user-interface timestamps.
9881 Before, the code sometimes used 'Time', sometimes 'unsigned long',
9882 and sometimes 'EMACS_UINT', to represent these timestamps.
9883 This change causes it to use 'Time' uniformly, as that's what X uses.
9884 This makes the code easier to follow, and makes it easier to catch
9885 integer overflow bugs such as Bug#8664.
9886 * frame.c (Fmouse_position, Fmouse_pixel_position):
9887 Use Time, not unsigned long, for user-interface timestamps.
9888 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
9889 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
9890 * keyboard.h (last_event_timestamp): Likewise.
9891 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
9892 * menu.h (xmenu_show): Likewise.
9893 * term.c (term_mouse_position): Likewise.
9894 * termhooks.h (struct input_event.timestamp): Likewise.
9895 (struct terminal.mouse_position_hook): Likewise.
9896 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
9897 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
9898 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
9899 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
9901 * menu.h, termhooks.h: Include "systime.h", for Time.
9903 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
9904 Don't assume that the difference between two unsigned long values
9905 can fit into an integer. At this point, we know button_down_time
9906 <= event->timestamp, so the difference must be nonnegative, so
9907 there's no need to cast the result if double-click-time is
9908 nonnegative, as it should be; check that it's nonnegative, just in
9909 case. This bug is triggered when events are more than 2**31 ms
9910 apart (about 25 days). (Bug#8664)
9912 * xselect.c (last_event_timestamp): Remove duplicate decl.
9913 (x_own_selection): Remove needless cast to unsigned long.
9915 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
9916 that always fit in int. Use a sentinel instead of a counter, to
9917 avoid a temp and to allay GCC's concerns about possible int overflow.
9918 * frame.h (struct frame): Use int for menu_bar_items_used
9919 instead of EMACS_INT, since it always fits in int.
9921 * menu.c (grow_menu_items): Check for int overflow.
9923 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
9925 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
9926 Before, the code was not consistent. These values cannot exceed
9927 2**31 - 1 so there's no need to make them unsigned.
9928 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
9929 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
9930 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
9932 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
9934 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
9935 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
9936 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
9937 presumably because the widths might not match.
9939 * window.c (size_window): Avoid needless test at loop start.
9941 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
9943 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
9945 2011-05-12 Drew Adams <drew.adams@oracle.com>
9947 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
9949 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9951 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
9952 `width' to `bar_area_x' and `bar_area_width', respectively.
9953 (x_scroll_run): Take account of fringe background extension.
9955 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
9956 Rename local vars `left' and `width' to `bar_area_x' and
9957 `bar_area_width', respectively.
9958 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
9959 background extension.
9961 2011-05-10 Jim Meyering <meyering@redhat.com>
9963 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
9965 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
9967 * image.c (Finit_image_library): Return t for built-in image types,
9968 like pbm and xbm. (Bug#8640)
9970 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
9972 * w32menu.c (set_frame_menubar): Fix submenu allocation.
9974 2011-05-07 Eli Zaretskii <eliz@gnu.org>
9976 * w32console.c (Fset_screen_color): Doc fix.
9977 (Fget_screen_color): New function.
9978 (syms_of_ntterm): Defsubr it.
9980 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
9981 unlink the temporary file if Fcall_process didn't create it in the
9983 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
9984 child process will be redirected to a file specified with `:file'.
9985 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
9986 cue to call_process_cleanup not to close that handle.
9988 2011-05-07 Ben Key <bkey76@gmail.com>
9990 * makefile.w32-in: The bootstrap-temacs rule now makes use of
9991 one of two shell specific rules, either bootstrap-temacs-CMD or
9992 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
9993 to the previous implementation of the bootstrap-temacs rule.
9994 The bootstrap-temacs-CMD rule is similar to the previous
9995 implementation of the bootstrap-temacs rule except that it
9996 makes use of the ESC_CFLAGS variable instead of the CFLAGS
9999 These changes, along with some changes to nt/configure.bat,
10000 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10001 earlier fix to add support for --cflags and --ldflags options
10002 that include quotes so that it works whether make uses cmd or
10005 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10007 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10008 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10010 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10011 a string. Handle both cases.
10012 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10013 (Fdbus_register_method): Use Qinvalid_function.
10015 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10017 * makefile.w32-in: Update dependencies.
10018 (LISP_H): Add inttypes.h and stdin.h.
10019 (PROCESS_H): Add unistd.h.
10021 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10023 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10024 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10026 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10028 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10030 * term.c (vfatal): Remove stray call to va_end.
10031 It's not needed and the C Standard doesn't allow it here anyway.
10033 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10034 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10036 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10039 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10041 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10043 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10045 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10047 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10049 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10050 * charset.c (Fdefine_charset_internal): Don't initialize
10051 charset.code_space[15]. The value was garbage, on hosts with
10052 32-bit int (Bug#8600).
10054 * lread.c (read_integer): Be more consistent with string-to-number.
10055 Use string_to_number to do the actual conversion; this avoids
10056 rounding errors and fixes some other screwups. Without this fix,
10057 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10058 (digit_to_number): Move earlier, for benefit of read_integer.
10059 Return -1 if the digit is out of range for the base, -2 if it is
10060 not a digit in any supported base. (Bug#8602)
10062 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10064 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10065 to match comment at start of function. This also removes a
10066 GCC warning about overflow in a 32+64-bit port.
10068 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10070 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10071 Reported by Stefan Monnier in
10072 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10073 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10074 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10076 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10077 (EMACS_UINTPTR): Likewise, with uintptr_t.
10079 * lisp.h: Prefer 64-bit EMACS_INT if available.
10080 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
10081 on 32-bit hosts that have 64-bit int, so that they can access
10083 However, temporarily disable this change unless the temporary
10084 symbol WIDE_EMACS_INT is defined.
10086 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
10088 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
10089 This removes an assumption that EMACS_INT and long are the same
10090 width as pointers. The assumption is true for Emacs porting targets
10091 now, but we want to make other targets possible.
10092 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
10093 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
10094 In the rest of the code, change types of integers that hold casted
10095 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
10096 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
10097 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
10098 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
10099 No need to cast type when ORing.
10100 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
10101 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
10102 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
10103 assume EMACS_INT is the same width as char *.
10104 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
10105 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
10106 Remove no-longer-needed casts.
10107 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
10108 (xg_tool_bar_help_callback, xg_make_tool_item):
10109 Use EMACS_INTPTR to hold an integer
10110 that will be cast to void *; this can avoid a GCC warning
10111 if EMACS_INT is not the same width as void *.
10112 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
10113 * xdisp.c (display_echo_area_1, resize_mini_window_1):
10114 (current_message_1, set_message_1):
10115 Use a local to convert to proper width without a cast.
10116 * xmenu.c (dialog_selection_callback): Likewise.
10118 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
10119 Also, don't assume VALBITS / RAND_BITS is less than 5,
10120 and don't rely on undefined behavior when shifting a 1 left into
10122 * lisp.h (get_random): Change signature to match.
10124 * lread.c (hash_string): Use size_t, not int, for hash computation.
10125 Normally we prefer signed values; but hashing is special, because
10126 it's better to use unsigned division on hash table sizes so that
10127 the remainder is nonnegative. Also, size_t is the natural width
10128 for hashing into memory. The previous code used 'int', which doesn't
10129 retain enough info to hash well into very large tables.
10130 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
10132 * dbusbind.c: Don't possibly lose pointer info when converting.
10133 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10134 Use XPNTR rather than XHASH, so that the high-order bits of
10135 the pointer aren't lost when converting through void *.
10137 * eval.c (Fautoload): Don't double-shift a pointer.
10139 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

10173 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
10174 Remove unused parameter `fildes'.
10175 * process.c (read_process_output, send_process): Don't pass it.
10177 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
10179 Fix previous change: the library cache is defined in w32.c.
10180 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
10181 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

10222 * process.c: Include lisp.h before w32.h, not after.
10223 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
10224 instead of gnutls_record_check_pending.
10226 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
10228 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
10230 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
10231 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
10234 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
10236 * xterm.c (x_set_frame_alpha): Do not set property on anything

10271 (Fcall_process_region): Ditto.
10273 2011-04-30 Eli Zaretskii <eliz@gnu.org>
10275 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
10276 rather than `XVECTOR (FOO)->size'.
10278 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
10279 inttypes.h, as a gnulib replacement is used if it not available in
10282 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10284 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
10285 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
10286 of MOST_POSITIVE_FIXNUM. (Bug#8528)
10288 * coding.c (coding_alloc_by_realloc): Error out if destination
10289 will grow beyond MOST_POSITIVE_FIXNUM.
10290 (decode_coding_emacs_mule): Abort if there isn't enough place in
10291 charbuf for the composition carryover bytes. Reserve an extra
10292 space for up to 2 characters produced in a loop.

10294 charbuf for the composition carryover bytes.
10296 2011-04-21 Eli Zaretskii <eliz@gnu.org>
10298 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
10299 aborting when %lld or %lll format is passed.

10307 produced by %s or %c overflows available buffer space. (Bug#8545)
10309 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
10311 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

10328 * doprnt.c (doprnt): Don't return value smaller than the buffer
10329 size if the message was truncated. (Bug#8545).
10331 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
10333 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

10346 Improve `doprnt' and its usage. (Bug#8545)
10347 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
10348 `format_end'. Remove support for %l as a conversion specifier.
10349 Don't use xrealloc. Improve diagnostics when the %l size modifier
10350 is used. Update the commentary.
10352 * eval.c (verror): Simplify calculation of size_t.
10354 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
10357 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
10359 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
10362 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
10364 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
10365 This makes this file independent of the recent pseudovector change.
10367 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
10369 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
10371 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
10372 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
10373 Remove unused local.
10374 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
10376 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
10377 GCC 4.6.0 optimizes based on type-based alias analysis.
10378 For example, if b is of type struct buffer * and v of type struct
10379 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
10380 != &v->size, and therefore "v->size = 1; b->size = 2; return
10381 v->size;" must therefore return 1. This assumption is incorrect
10382 for Emacs, since it type-puns struct Lisp_Vector * with many other
10383 types. To fix this problem, this patch adds a new type struct
10384 vectorlike_header that documents the constraints on layout of vectors
10385 and pseudovectors, and helps optimizing compilers not get fooled
10386 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
10387 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
10388 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
10390 (XSETPVECTYPE): Rewrite in terms of new macro.
10391 (XSETPVECTYPESIZE): New macro, specifying both type and size.
10392 This is a bit clearer, and further avoids the possibility of
10393 undesirable aliasing.
10394 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
10395 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
10396 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
10397 since Lisp_Subr is a special case (no "next" field).
10398 (ASIZE): Now uses header.size rather than size.
10399 All previous uses of XVECTOR (foo)->size replaced to use this macro,
10400 to avoid the hassle of writing XVECTOR (foo)->header.size.
10401 (struct vectorlike_header): New type.
10402 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
10403 object, to help avoid aliasing.
10404 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
10405 (SUBRP): Likewise, since Lisp_Subr is a special case.
10406 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
10407 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
10408 (struct Lisp_Hash_Table): Combine first two members into a single
10409 struct vectorlike_header member. All uses of "size" and "next" members
10410 changed to be "header.size" and "header.next".
10411 * buffer.h (struct buffer): Likewise.
10412 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
10413 * frame.h (struct frame): Likewise.
10414 * process.h (struct Lisp_Process): Likewise.
10415 * termhooks.h (struct terminal): Likewise.
10416 * window.c (struct save_window_data, struct saved_window): Likewise.
10417 * window.h (struct window): Likewise.
10418 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
10419 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
10420 * buffer.c (init_buffer_once): Likewise.
10421 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
10423 * process.c (Fformat_network_address): Use local var for size,
10426 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
10428 Make the Lisp reader and string-to-float more consistent (Bug#8525)
10429 * data.c (atof): Remove decl; no longer used or needed.
10430 (digit_to_number): Move to lread.c.
10431 (Fstring_to_number): Use new string_to_number function, to be
10432 consistent with how the Lisp reader treats infinities and NaNs.
10433 Do not assume that floating-point numbers represent EMACS_INT
10434 without losing information; this is not true on most 64-bit hosts.
10435 Avoid double-rounding errors, by insisting on integers when
10436 parsing non-base-10 numbers, as the documentation specifies.
10437 * lisp.h (string_to_number): New decl, replacing ...
10438 (isfloat_string): Remove.
10439 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
10440 (read1): Do not accept +. and -. as integers; this
10441 appears to have been a coding error. Similarly, do not accept
10442 strings like +-1e0 as floating point numbers. Do not report
10443 overflow for integer overflows unless the base is not 10 which
10444 means we have no simple and reliable way to continue.
10445 Break out the floating-point parsing into a new
10446 function string_to_number, so that Fstring_to_number parses
10447 floating point numbers consistently with the Lisp reader.
10448 (digit_to_number): Move here from data.c. Make it static inline.
10449 (E_CHAR, EXP_INT): Remove, replacing with ...
10450 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
10451 (string_to_number): New function, replacing isfloat_string.
10452 This function checks for valid syntax and produces the resulting
10453 Lisp float number too. Rework it so that string-to-number
10454 no longer mishandles examples like "1.0e+". Use strtoumax,
10455 so that overflow for non-base-10 numbers is reported only when
10456 there's no portable and simple way to convert to floating point.
10458 * textprop.c (set_text_properties_1): Rewrite for clarity,
10459 and to avoid GCC warning about integer overflow.
10461 * intervals.h (struct interval): Use EMACS_INT for members
10462 where EMACS_UINT might cause problems. See
10463 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
10464 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
10465 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
10467 (offset_intervals): Tell GCC not to worry about length overflow
10468 when negating a negative length.
10470 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
10471 (overrun_check_free): Likewise.
10473 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
10474 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
10477 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10478 (gnutls_make_error): Rename local to avoid shadowing.
10479 (gnutls_emacs_global_deinit): ifdef out; not used.
10480 (Fgnutls_boot): Use const for pointer to readonly storage.
10481 Comment out unused local. Fix pointer signedness problems.
10483 * lread.c (openp): Don't stuff size_t into an 'int'.
10484 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
10485 about possible signed overflow.
10487 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
10488 (GDK_KEY_g): Don't define if already defined.
10489 (xg_prepare_tooltip): Avoid pointer signedness problem.
10490 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
10492 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
10493 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
10495 * xfns.c (Fx_window_property): Simplify a bit,
10496 to make a bit faster and to avoid GCC 4.6.0 warning.
10497 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
10499 * fns.c (internal_equal): Don't assume size_t fits in int.
10501 * alloc.c (compact_small_strings): Tighten assertion a little.
10503 Replace pEd with more-general pI, and fix some printf arg casts.
10504 * lisp.h (pI): New macro, generalizing old pEd macro to other
10505 conversion specifiers. For example, use "...%"pI"d..." rather
10506 than "...%"pEd"...".
10507 (pEd): Remove. All uses replaced with similar uses of pI.
10508 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
10509 * alloc.c (check_pure_size): Don't overflow by converting size to int.
10510 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
10511 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
10512 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
10513 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
10514 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
10516 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
10517 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
10518 * print.c (safe_debug_print, print_object): Likewise.
10519 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
10521 Use pI instead of if-then-else-abort. Use %p to avoid casts,
10522 avoiding the 0 flag, which is not portable.
10523 * process.c (Fmake_network_process): Use pI to avoid cast.
10524 * region-cache.c (pp_cache): Likewise.
10525 * xdisp.c (decode_mode_spec): Likewise.
10526 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined

10529 (x_stop_queuing_selection_requests): Likewise.
10530 (x_get_window_property): Don't truncate byte count to an 'int'
10533 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
10534 here, since it parses constructs like leading '-' and spaces,
10535 which are not wanted; and it overflows with large numbers.
10536 Instead, simply match F[0-9]+, which is what is wanted anyway.
10538 * alloc.c: Remove unportable assumptions about struct layout.
10539 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
10540 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
10541 (allocate_vectorlike, make_pure_vector): Use the new macros,
10542 plus offsetof, to remove unportable assumptions about struct layout.
10543 These assumptions hold on all porting targets that I know of, but
10544 they are not guaranteed, they're easy to remove, and removing them
10545 makes further changes easier.
10547 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
10548 This doesn't fix a bug but makes the code clearer.
10549 (string_overrun_cookie): Now const. Use initializers that
10550 don't formally overflow signed char, to avoid warnings.
10551 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
10552 can cause Emacs to crash when string overrun checking is enabled.
10553 (allocate_buffer): Don't assume sizeof (struct buffer) is a
10554 multiple of sizeof (EMACS_INT); it need not be, if
10555 alignof(EMACS_INT) < sizeof (EMACS_INT).
10556 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

10587 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
10588 "cast to pointer from integer of different size".
10590 Improve doprnt and its use in verror. (Bug#8545)
10591 * doprnt.c (doprnt): Document the set of format control sequences
10592 supported by the function. Use SAFE_ALLOCA instead of always
10595 * eval.c (verror): Don't limit the buffer size at size_max-1, that
10596 is one byte too soon. Don't use xrealloc; instead xfree and
10599 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>

10608 docstring. Start callback support.
10609 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake

10714 codepoint of an invalid character, to avoid displaying a bogus
10717 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
10718 `error', not SYMBOL_NAME itself.
10720 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

10723 * charset.c (check_iso_charset_parameter): Fix incorrect argument
10724 to `error' in error message about FINAL_CHAR argument. Make sure
10725 FINAL_CHAR is a character, and use %c when it is passed as
10726 argument to `error'.
10728 2011-04-23 Eli Zaretskii <eliz@gnu.org>
10730 * s/ms-w32.h (localtime): Redirect to sys_localtime.
10732 * w32.c: Include <time.h>.

10796 * dispextern.h (struct redisplay_interface): Rename param
10797 to avoid shadowing.
10798 * termhooks.h (struct terminal): Likewise.

10915 * nsfont.m: Fixed bugs in ns_get_family and
10916 ns_descriptor_to_entity that were caused by using free to
10917 deallocate memory blocks that were allocated by xmalloc (via
10918 xstrdup). This caused Emacs to crash when compiled with
10919 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
10920 --enable-checking=xmallocoverrun). xfree is now used to
10921 deallocate these memory blocks.

10935 (emacs_read, emacs_write): Remove check for negative size, as the
10936 Emacs source code has been audited now.
10937 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
10938 (emacs_read, emacs_write): Use it.
10939 * process.c (send_process): Adjust to the new signatures of
10940 emacs_write and emacs_gnutls_write. Do not attempt to store
10941 a byte offset into an 'int'; it might overflow.
10942 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

11394 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
11396 * charset.c (Fclear_charset_maps): Use xfree instead of free.
11398 * keyboard.c (parse_tool_bar_item): Likewise.
11399 * sound.c (sound_cleanup, alsa_close): Likewise.
11400 * termcap.c (tgetent): Likewise.
11401 * xfns.c (x_default_font_parameter): Likewise.
11402 * xsettings.c (read_and_apply_settings): Likewise.
11404 * alloc.c (overrun_check_malloc, overrun_check_realloc)
11405 (overrun_check_free): Protoize.
11407 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
11409 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
11410 since callers should never pass a negative size.
11411 Change the signature to match that of plain 'read' and 'write'; see
11412 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
11413 * lisp.h: Update prototypes of emacs_write and emacs_read.
11415 2011-04-11 Eli Zaretskii <eliz@gnu.org>
11417 * xdisp.c (redisplay_window): Don't try to determine the character
11418 position of the scroll margin if the window start point w->startp
11419 is outside the buffer's accessible region. (Bug#8468)
11421 2011-04-10 Eli Zaretskii <eliz@gnu.org>
11423 Fix write-region and its subroutines for buffers > 2GB.
11424 * fileio.c (a_write, e_write): Modify declaration of arguments and
11425 local variables to support buffers larger than 2GB.
11426 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
11428 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
11429 argument, local variables, and return value.
11431 * lisp.h: Update prototypes of emacs_write and emacs_read.
11433 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
11435 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
11437 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
11439 Fix more problems found by GCC 4.6.0's static checks.
11441 * xdisp.c (vmessage): Use a better test for character truncation.
11443 * charset.c (load_charset_map): <, not <=, for optimization,
11444 and to avoid potential problems with integer overflow.
11445 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
11446 * casetab.c (set_identity, shuffle): Likewise.
11447 * editfns.c (Fformat): Likewise.
11448 * syntax.c (skip_chars): Likewise.
11450 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
11451 This also lets GCC 4.6.0 generate slightly better loop code.
11453 * callint.c (Fcall_interactively): <, not <=, for optimization.
11454 (Fcall_interactively): Count the number of arguments produced,
11455 not the number of arguments given. This is simpler and lets GCC
11456 4.6.0 generate slightly better code.
11458 * ftfont.c: Distingish more carefully between FcChar8 and char.
11459 The previous code passed unsigned char * to a functions like
11460 strlen and xstrcasecmp that expect char *, which does not
11461 conform to the C standard.
11462 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
11463 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
11464 char * when the C standard requires it.
11466 * keyboard.c (read_char): Remove unused var.
11468 * eval.c: Port to Windows vsnprintf (Bug#8435).
11469 Include <limits.h>.
11470 (SIZE_MAX): Define if the headers do not.
11471 (verror): Do not give up if vsnprintf returns a negative count.
11472 Instead, grow the buffer. This ports to Windows vsnprintf, which
11473 does not conform to C99. Problem reported by Eli Zaretskii.
11474 Also, simplify the allocation scheme, by avoiding the need for
11475 calling realloc, and removing the ALLOCATED variable.
11477 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
11479 Remove invocations of doprnt, as Emacs now uses vsnprintf.
11480 But keep the doprint source code for now, as we might revamp it
11481 and use it again (Bug#8435).
11482 * lisp.h (doprnt): Remove.
11483 * Makefile.in (base_obj): Remove doprnt.o.
11484 * deps.mk (doprnt.o): Remove.
11486 error: Print 32- and 64-bit integers portably (Bug#8435).
11487 Without this change, on typical 64-bit hosts error ("...%d...", N)
11488 was used to print both 32- and 64-bit integers N, which relied on
11489 undefined behavior.
11490 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
11491 * lisp.h (error, verror): Mark as printf-like functions.
11492 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
11493 Report overflow in size calculations when allocating printf buffer.
11494 Do not truncate output string at its first null byte.
11495 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
11496 Truncate the output at a character boundary, since vsnprintf does not
11498 * charset.c (check_iso_charset_parameter): Convert internal
11499 character to string before calling 'error', since %c now has the
11501 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
11502 overflow when computing char to be passed to 'error'. Do not
11503 pass Lisp_Object to 'error'; pass the integer instead.
11504 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
11505 formatted with plain %d.
11507 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
11509 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
11511 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
11513 * xterm.c (x_catch_errors): Remove duplicate declaration.
11515 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
11517 * xdisp.c, lisp.h (message_nolog): Remove; unused.
11519 2011-04-10 Jim Meyering <meyering@redhat.com>
11521 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
11522 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
11523 return ssize_t not "int", and use size_t as the buffer length.
11524 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
11525 * gnutls.h: Update declarations.
11526 * process.c (read_process_output): Use ssize_t, to match.
11527 (send_process): Likewise.
11529 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11531 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
11533 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
11535 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
11536 Use unsigned char, to match FcChar8 type definition.
11538 * xterm.c (handle_one_xevent):
11539 * xmenu.c (create_and_show_popup_menu):
11540 * xselect.c (x_decline_selection_request)
11541 (x_reply_selection_request): Avoid type-punned deref of X events.
11543 2011-04-09 Eli Zaretskii <eliz@gnu.org>
11545 Fix some uses of `int' instead of EMACS_INT.
11546 * search.c (string_match_1, fast_string_match)
11547 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
11548 (scan_buffer, find_next_newline_no_quit)
11549 (find_before_next_newline, search_command, Freplace_match)
11550 (Fmatch_data): Make some `int' variables be EMACS_INT.
11552 * xdisp.c (display_count_lines): 3rd argument and return value now
11553 EMACS_INT. All callers changed.
11554 (pint2hrstr): Last argument is now EMACS_INT.
11556 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
11557 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
11558 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
11559 (decode_coding_utf_16, decode_coding_emacs_mule)

11561 (decode_coding_ccl, decode_coding_charset)
11562 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
11563 (decode_coding_iso_2022, decode_coding_emacs_mule)
11564 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
11565 <char_offset, last_offset>: Declare EMACS_INT.
11566 (encode_coding_utf_8, encode_coding_utf_16)
11567 (encode_coding_emacs_mule, encode_invocation_designation)
11568 (encode_designation_at_bol, encode_coding_iso_2022)
11569 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
11570 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
11572 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
11573 (encode_invocation_designation): Last argument P_NCHARS is now
11575 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
11576 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
11578 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
11581 * ccl.c (Fccl_execute_on_string): Declare some variables
11584 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
11586 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
11588 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
11590 * process.c (Fformat_network_address): Doc fix.
11592 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
11594 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
11596 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
11598 * keyboard.c (read_char): Call Lisp function help-form-show,
11599 instead of using internal_with_output_to_temp_buffer.
11600 (Qhelp_form_show): New var.
11601 (syms_of_keyboard): Use DEFSYM macro.
11603 * print.c (internal_with_output_to_temp_buffer): Function deleted.
11605 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
11607 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
11609 * process.c (Flist_processes): Remove to Lisp.
11610 (list_processes_1): Delete.

11614 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
11616 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
11618 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
11620 Fix more problems found by GCC 4.6.0's static checks.
11622 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
11624 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
11626 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
11628 * xdisp.c (vmessage): Mark as a printf-like function.
11630 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
11632 * sound.c (sound_warning): Don't crash if arg contains a printf format.
11634 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
11635 printf-like functions.
11636 (tiff_load): Add casts to remove these marks before passing them
11637 to system-supplied API.
11639 * eval.c (Fsignal): Remove excess argument to 'fatal'.
11641 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
11642 This avoids several warnings with gcc -Wstrict-overflow.
11643 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
11644 directly, rather than having caller test rule sign. This avoids
11645 some unnecessary tests.
11646 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
11647 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
11648 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
11650 * xfont.c (xfont_text_extents): Remove var that was set but not used.
11651 (xfont_open): Avoid unnecessary tests.
11653 * composite.c (composition_gstring_put_cache): Use unsigned integer.
11655 * composite.h, composite.c (composition_gstring_put_cache):
11656 Use EMACS_INT, not int, for length.

11659 breaking out part of COMPOSITION_DECODE_RULE.
11660 (COMPOSITION_DECODE_RULE): Use it.
11661 * composite.c (get_composition_id): Remove unused local vars,
11662 by using the new macro.
11664 * textprop.c (set_text_properties_1): Change while to do-while,
11665 since the condition is always true at first.
11667 * intervals.c (graft_intervals_into_buffer): Mark var as used.
11668 (interval_deletion_adjustment): Return unsigned value.
11671 * process.c (list_processes_1, create_pty, read_process_output):
11672 (exec_sentinel): Remove vars that were set but not used.
11673 (create_pty): Remove unnecessary "volatile"s.

11681 (update_syntax_table): Use unsigned instead of int.
11683 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
11684 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
11685 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
11687 * print.c (print_error_message): Avoid int overflow.
11689 * font.c (font_list_entities): Redo for clarity,
11690 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
11692 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
11693 (font_score): Avoid potential overflow in diff calculation.
11695 * fns.c (substring_both): Remove var that is set but not used.
11696 (sxhash): Redo loop for clarity and to avoid wraparound warning.
11698 * eval.c (funcall_lambda): Rename local to avoid shadowing.
11700 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
11701 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
11702 can always succeed if overflow has undefined behavior.
11704 * search.c (boyer_moore, wordify): Remove vars set but not used.
11705 (wordify): Omit three unnecessary tests.
11707 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
11708 All callers changed. This avoids the need for an unused var.
11710 * casefiddle.c (casify_region): Remove var that is set but not used.
11712 * dired.c (file_name_completion): Remove var that is set but not used.
11714 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
11716 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
11717 (Finsert_file_contents): Remove unnecessary code checking fd.
11719 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
11720 Check for integer overflow on size calculations.
11722 * buffer.c (Fprevious_overlay_change): Remove var that is set
11725 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
11726 Remove vars that are set but not used.
11727 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
11728 (timer_check_2): Mark vars as initialized.
11730 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
11732 * image.c (lookup_image): Remove var that is set but not used.
11733 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
11735 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
11736 that are set but not used.
11738 * xfns.c (make_invisible_cursor): Don't return garbage
11739 if XCreateBitmapFromData fails (Bug#8410).
11741 * xselect.c (x_get_local_selection, x_handle_property_notify):
11742 Remove vars that are set but not used.
11744 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

11754 (map_tty_color) [!defined MSDOS]: Likewise.
11756 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
11758 * coding.c: Remove vars that are set but not used.
11759 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
11760 All callers changed.
11761 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
11762 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
11763 (decode_coding_charset): Remove vars that are set but not used.
11765 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
11766 that is set but not used.
11768 * print.c (print_object): Remove var that is set but not used.
11770 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
11771 The gnulib version avoids calling malloc in the usual case,
11772 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
11773 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
11774 * filelock.c (current_lock_owner): Likewise.
11775 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
11776 * sysdep.c: Include allocator.h, careadlinkat.h.
11777 (emacs_no_realloc_allocator): New static constant.
11778 (emacs_readlink): New function.
11779 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
11780 ../lib/careadlinkat.h.
11782 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
11784 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
11785 first non-nil return value).
11787 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
11789 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
11790 if not defined (Bug#8403).

11794 * xdisp.c (display_count_lines): Remove parameter `start',
11795 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

11799 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
11800 and thereabouts. All callers changed.
11801 (get_per_char_metric): Remove parameter `f', unused since
11802 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

11806 do not dereference NULL upon failed strdup
11807 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
11808 (ns_get_family): Likewise.
11810 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
11812 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

11850 (Feval): New `lexical' arg.
11851 (eval_sub): New function extracted from Feval. Use it almost
11852 everywhere where Feval was used. Look up vars in lexical env.
11854 (Ffunctionp): Move from subr.el.
11855 (Ffuncall): Handle closures.
11856 (apply_lambda): Remove `eval_flags'.
11857 (funcall_lambda): Handle closures and new byte-code-functions.
11858 (Fspecial_variable_p): New function.
11859 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
11860 but without exporting it to Lisp.
11862 * doc.c (Fdocumentation, store_function_docstring):
11863 * data.c (Finteractive_form): Handle closures.
11865 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
11868 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
11870 (exec_byte_code): New function extracted from Fbyte_code to handle new
11871 calling convention for byte-code-functions. Add new byte-codes.
11873 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
11875 * alloc.c (Fmake_symbol): Init new `declared_special' field.
11877 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
11879 * xdisp.c (redisplay_internal): Fix prototype.
11881 2011-03-31 Eli Zaretskii <eliz@gnu.org>
11883 * xdisp.c (SCROLL_LIMIT): New macro.
11884 (try_scrolling): Use it when setting scroll_limit.
11885 Limit scrolling to 100 screen lines.
11886 (redisplay_window): Even when falling back on "recentering",
11887 position point in the window according to scroll-conservatively,
11888 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
11890 (try_scrolling): When point is above the window, allow searching
11891 as far as scroll_max, or one screenful, to compute vertical
11892 distance from PT to the scroll margin position. This prevents
11893 try_scrolling from unnecessarily failing when
11894 scroll-conservatively is set to a value slightly larger than the
11895 window height. Clean up the case of PT below the margin at bottom
11896 of window: scroll_max can no longer be INT_MAX. When aggressive
11897 scrolling is in use, don't let point enter the opposite scroll
11898 margin as result of the scroll.
11899 (syms_of_xdisp) <scroll-conservatively>: Document the
11900 threshold of 100 lines for never-recentering scrolling.
11902 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
11904 * dispextern.h (move_it_by_lines):
11905 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
11906 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
11907 (message_log_check_duplicate): Remove parameters `prev_bol' and
11908 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
11909 (redisplay_internal): Remove parameter `preserve_echo_area',
11910 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
11912 * indent.c (Fvertical_motion):
11913 * window.c (window_scroll_pixel_based, Frecenter):
11914 Don't pass `need_y_p' to `move_it_by_lines'.
11916 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
11918 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
11919 steal a few bits to be more compact.
11920 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
11921 Remove unneeded casts.
11923 * bytecode.c (Fbyte_code): CAR and CDR can GC.
11925 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
11927 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
11928 binding" message (bug#7967).
11930 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
11932 Fix more problems found by GCC 4.6.0's static checks.
11934 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
11935 Remove unused local var.
11937 * editfns.c (Fmessage_box): Remove unused local var.
11939 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
11940 (note_mode_line_or_margin_highlight, note_mouse_highlight):
11941 Omit unused local vars.
11942 * window.c (shrink_windows): Omit unused local var.
11943 * menu.c (digest_single_submenu): Omit unused local var.
11944 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
11945 Omit unused local var.
11947 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
11948 Don't assume string length fits in int.
11949 (keyremap_step, read_key_sequence): Use size_t for sizes.
11950 (read_key_sequence): Don't check last_real_key_start redundantly.
11952 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
11953 instead of alloca (Bug#8344).
11955 * eval.c (Fbacktrace): Don't assume nargs fits in int.
11956 (Fbacktrace_frame): Don't assume nframes fits in int.
11958 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
11960 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
11963 * term.c (produce_glyphless_glyph): Remove unnecessary test.
11965 * cm.c (calccost): Turn while-do into do-while, for clarity.
11967 * keyboard.c (syms_of_keyboard): Use the same style as later
11968 in this function when indexing through an array. This also
11969 works around GCC bug 48267.
11971 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
11973 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
11975 * chartab.c (sub_char_table_ref_and_range): Redo for slight
11976 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
11978 * keyboard.c, keyboard.h (num_input_events): Now size_t.
11979 This avoids undefined behavior on integer overflow, and is a bit
11980 more convenient anyway since it is compared to a size_t variable.
11982 Variadic C functions now count arguments with size_t, not int.
11983 This avoids an unnecessary limitation on 64-bit machines, which
11984 caused (substring ...) to crash on large vectors (Bug#8344).
11985 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
11986 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
11987 All variadic functions and their callers changed accordingly.
11988 (struct gcpro.nvars): Now size_t, not int. All uses changed.

11990 * editfns.c (general_insert_function): Likewise.
11991 * eval.c (struct backtrace.nargs, interactive_p)
11992 (internal_condition_case_n, run_hook_with_args, apply_lambda)
11993 (funcall_lambda, mark_backtrace): Likewise.
11994 * fns.c (concat): Likewise.
11995 * frame.c (x_set_frame_parameters): Likewise.
11996 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
11997 0 if not found, not -1. All callers changed.
11999 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12000 (stack_copy_size): Now size_t, not int.
12001 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12003 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12005 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
12006 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12007 All callers changed.
12009 * lisp.h (multibyte_char_to_unibyte):
12010 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
12011 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
12012 * character.h (CHAR_TO_BYTE8):
12013 * cmds.c (internal_self_insert):
12014 * editfns.c (general_insert_function):
12015 * keymap.c (push_key_description):
12016 * search.c (Freplace_match):
12017 * xdisp.c (message_dolog, set_message_1): All callers changed.
12019 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12021 * keyboard.c (safe_run_hook_funcall): New function.
12022 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12023 don't set the hook to nil, but remove the offending function instead.
12024 (Qcommand_hook_internal): Remove, unused.
12025 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12026 Vcommand_hook_internal.
12028 * eval.c (enum run_hooks_condition): Remove.
12029 (funcall_nil, funcall_not): New functions.
12030 (run_hook_with_args): Call each function through a `funcall' argument.
12031 Remove `cond' argument, now redundant.
12032 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
12033 (Frun_hook_with_args_until_failure): Adjust accordingly.
12034 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
12036 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12038 * dispextern.h (string_buffer_position): Remove declaration.
12040 * print.c (strout): Remove parameter `multibyte', unused since
12041 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
12043 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
12044 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
12045 All callers changed.
12047 * w32.c (_wsa_errlist): Use braces for struct initializers.
12049 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
12050 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
12051 All callers changed.
12052 (string_buffer_position): Likewise. Also, make static (it's never
12053 used outside xdisp.c).
12054 (cursor_row_p): Remove parameter `w', unused since
12055 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

12057 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
12058 All callers changed.
12060 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12062 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

12067 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
12068 (ns_update_auto_hide_menu_bar): New functions.
12069 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

12073 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
12075 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
12077 * nsmenu.m (runDialogAt): Remove argument to timer_check.
12079 2011-03-27 Glenn Morris <rgm@gnu.org>
12081 * syssignal.h: Replace RETSIGTYPE with void.
12082 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
12083 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
12084 Replace SIGTYPE with void everywhere.
12085 * s/usg5-4-common.h (SIGTYPE): Remove definition.
12086 * s/template.h (SIGTYPE): Remove commented out definition.
12088 2011-03-26 Eli Zaretskii <eliz@gnu.org>
12090 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
12091 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
12093 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
12095 * w32.c (read_unc_volume): Use parameter `henum', instead of
12096 global variable `wget_enum_handle'.
12098 * keymap.c (describe_vector): Remove parameters `indices' and
12099 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
12100 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
12102 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
12104 * keyboard.c (timer_check): Remove parameter `do_it_now',
12105 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
12106 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
12107 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
12109 * keyboard.c (read_char):
12110 * w32menu.c (w32_menu_display_help):
12111 * xmenu.c (show_help_event, menu_help_callback):
12112 Adjust calls to `show_help_echo'.
12114 * gtkutil.c (xg_maybe_add_timer):
12115 * keyboard.c (readable_events):
12116 * process.c (wait_reading_process_output):
12117 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
12119 * insdel.c (adjust_markers_gap_motion):
12120 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
12121 (gap_left, gap_right): Don't call it.
12123 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
12125 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
12126 incurred during fontification.

12167 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
12169 * w32term.c (x_set_glyph_string_clipping):
12170 Don't pass uninitialized region to CombineRgn.
12172 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
12174 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
12175 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
12176 (Fx_close_connection): Remove unused variable `i'.
12178 * w32font.c (w32font_draw): Return number of glyphs.
12179 (w32font_open_internal): Remove unused variable `i'.

12192 (uniscribe_font_driver): Add missing initializers.
12194 2011-03-23 Julien Danjou <julien@danjou.info>
12196 * term.c (Fsuspend_tty, Fresume_tty):
12197 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
12198 * window.c (temp_output_buffer_show):
12199 * insdel.c (signal_before_change):
12200 * frame.c (Fhandle_switch_frame):
12201 * fileio.c (Fdo_auto_save):
12202 * emacs.c (Fkill_emacs):
12203 * editfns.c (save_excursion_restore):
12204 * cmds.c (internal_self_insert):
12205 * callint.c (Fcall_interactively):
12206 * buffer.c (Fkill_all_local_variables):
12207 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
12209 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
12210 unconditionally since it does the check itself.
12212 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
12214 Fix more problems found by GCC 4.5.2's static checks.
12216 * coding.c (encode_coding_raw_text): Avoid unnecessary test
12217 the first time through the loop, since we know p0 < p1 then.
12218 This also avoids a gcc -Wstrict-overflow warning.
12220 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
12221 leading to a memory leak, possible in functions like
12222 load_charset_map_from_file that can allocate an unbounded number
12223 of objects (Bug#8318).
12225 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
12226 that could (at least in theory) be that large.
12228 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
12229 This is less likely to overflow, and avoids undefined behavior if
12230 overflow does occur. All callers changed. Use strtoul to scan
12231 for the unsigned long integer.
12232 (pint2hrstr): Simplify and tune code slightly.
12233 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
12235 * scroll.c (do_scrolling): Work around GCC bug 48228.
12236 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
12238 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
12239 This also avoids a warning with gcc -Wstrict-overflow.
12240 (validate_x_resource_name): Simplify count usage.
12241 This also avoids a warning with gcc -Wstrict-overflow.
12243 * fileio.c (Fcopy_file): Report error if fchown or fchmod
12246 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
12248 * process.c (Fmake_network_process): Use socklen_t, not int,
12249 where POSIX says socklen_t is required in portable programs.
12250 This fixes a porting bug on hosts like 64-bit HP-UX, where
12251 socklen_t is wider than int (Bug#8277).
12252 (Fmake_network_process, server_accept_connection):
12253 (wait_reading_process_output, read_process_output):
12256 * process.c: Rename or move locals to avoid shadowing.
12257 (list_processes_1, Fmake_network_process):
12258 (read_process_output_error_handler, exec_sentinel_error_handler):
12259 Rename or move locals.
12260 (Fmake_network_process): Define label "retry_connect" only if needed.
12261 (Fnetwork_interface_info): Fix pointer signedness.
12262 (process_send_signal): Add cast to avoid pointer signedness problem.
12263 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
12264 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
12266 Make tparam.h and terminfo.c consistent.
12267 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
12268 Include tparam.h instead, since it declares them.
12269 * cm.h (PC): Remove extern decl; tparam.h now does this.
12270 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
12271 * terminfo.c: Include tparam.h, to check interfaces.
12272 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
12273 (tparam): Adjust signature to match interface in tparam.h;
12274 this removes some undefined behavior. Check that outstring and len
12275 are zero, which they always are with Emacs.
12276 * tparam.h (PC, BC, UP): New extern decls.
12278 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
12279 (xftfont_open): Rename locals to avoid shadowing.
12281 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
12282 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

12330 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
12332 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
12333 This should get cleaned up, so that child_setup has the
12334 same signature on all platforms.
12336 * callproc.c (call_process_cleanup): Now static.
12337 (relocate_fd): Rename locals to avoid shadowing.
12339 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

12506 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12507 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
12508 to use the following functions instead of these macros.
12509 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
12510 EMACS_INT, since callers assume the returned value fits in int.
12511 (upcase1): Likewise, for UPCASE_TABLE.
12512 (uppercasep, lowercasep, upcase): New static inline functions.
12513 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

12523 (regex_compile, re_match_2_internal): Mark locals as initialized.
12524 (RETALLOC_IF): Define only if needed.
12525 (WORDCHAR_P): Likewise. This one is never needed, but is used
12526 only in a comment talking about a compiler bug, so put inside
12527 the #if 0 of that comment.
12528 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
12529 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

12556 New macros, so that the caller can use some names other than
12557 gcpro1, gcpro2, etc.
12558 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
12560 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
12561 argument, for consistency with GCPRO2_VAR, etc: it is now the
12562 prefix of the variable, not the variable itself. All uses
12564 * dired.c (directory_files_internal, file_name_completion):
12565 Rename locals to avoid shadowing.
12567 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
12568 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
12569 dired.c's scmp function, had undefined behavior.
12570 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
12571 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
12572 * buffer.h: ... to here, because these macros use current_buffer,
12573 and the new implementation with inline functions needs to have
12574 current_buffer in scope now, rather than later when the macros
12576 (downcase, upcase1): New static inline functions.
12577 (DOWNCASE, UPCASE1): Reimplement using these functions.
12578 This avoids undefined behavior in expressions like
12579 DOWNCASE (x) == DOWNCASE (y), which previously suffered
12580 from race conditions in accessing the global variables
12581 case_temp1 and case_temp2.
12582 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
12583 * lisp.h (case_temp1, case_temp2): Remove their decls.
12584 * character.h (ASCII_CHAR_P): Move from here ...
12585 * lisp.h: ... to here, so that the inline functions mentioned
12586 above can use them.
12588 * dired.c (directory_files_internal_unwind): Now static.
12590 * fileio.c (file_name_as_directory, directory_file_name):

12593 (file_name_as_directory): Use const pointers when appropriate.
12594 (Fexpand_file_name): Likewise. In particular, newdir might
12595 point at constant storage, so make it a const pointer.
12596 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
12597 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
12599 (Fset_file_times, Finsert_file_contents, auto_save_error):

12604 to avoid shadowing.
12606 * marker.c (bytepos_to_charpos): Remove; unused.
12608 * lisp.h (verify_bytepos, count_markers): New decls,
12609 so that gcc does not warn that these functions aren't declared.
12611 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
12612 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
12613 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
12614 (copy_text): Remove unused local var.
12616 * filelock.c (within_one_second): Now static.
12617 (lock_file_1): Rename local to avoid shadowing.
12619 * buffer.c (fix_overlays_before): Mark locals as initialized.
12620 (fix_start_end_in_overlays): Likewise. This function should be
12621 simplified by using pointers-to-pointers, but that's a different
12623 (switch_to_buffer_1): Now static.
12624 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
12625 (report_overlay_modification): Rename locals to avoid shadowing.

12628 Fix pointer signedness issue.
12629 (sys_subshell): Mark local as volatile if checking for lint,
12630 to suppress a gcc -Wclobbered warning that does not seem to be right.
12631 (MAXPATHLEN): Define only if needed.
12633 * process.c (serial_open, serial_configure): Move decls from here ...
12634 * systty.h: ... to here, so that they can be checked.
12636 * fns.c (get_random, seed_random): Move extern decls from here ...
12637 * lisp.h: ... to here, so that they can be checked.
12639 * sysdep.c (reset_io): Now static.
12640 (wait_for_termination_signal): Remove; unused.

12648 (describe_map_tree):
12649 Rename locals to avoid shadowing.
12651 * keyboard.c: Declare functions static if they are not used elsewhere.
