3 On assertion failure, print backtrace if available.
4 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6 * Makefile.in (LIB_EXECINFO): New macro.
9 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
10 * bytecode.c (exec_byte_code):
11 * callint.c (check_mark, Fcall_interactively):
12 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
13 (getenv_internal, sync_process_alive, call_process_exited):
14 * lisp.h (USE_SAFE_ALLOCA):
15 Use bool for booleans, instead of int.
16 * lisp.h, process.h: Adjust prototypes to match above changes.
17 * callint.c (Fcall_interactively): Don't assume the mark's
20 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
22 * buffer.c, buffer.h: Use bool for boolean.
23 * buffer.c (reset_buffer_local_variables)
24 (buffer_lisp_local_variables, Fset_buffer_modified_p)
25 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
26 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
27 (overlay_touches_p, overlay_strings, Foverlay_put)
28 (report_overlay_modification, call_overlay_mod_hooks):
29 (mmap_enlarge, mmap_set_vars):
30 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
31 Use bool for booleans, instead of int.
32 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
33 since the 1-or-0 return value is always ignored anyway.
35 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
36 * buffer.h, lisp.h: Adjust prototypes to match above changes.
38 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
40 * bidi.c: Use bool for boolean.
41 This is a bit more readable, and makes the text segment of bidi.o
42 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
43 Presumably it's faster too.
44 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
46 (bidi_cache_find_level_change, bidi_cache_iterator_state)
47 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
48 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
49 (bidi_explicit_dir_char, bidi_level_of_next_char)
50 (bidi_find_other_level_edge, bidi_move_to_visually_next):
51 Use bool for booleans, instead of int.
52 * dispextern.h (bidi_init_it, bidi_paragraph_init)
53 (bidi_unshelve_cache): Adjust decls to match code.
55 2012-08-23 Martin Rudalics <rudalics@gmx.at>
57 * keyboard.c (Fposn_at_x_y): Do not allow internal window as

62 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
63 * atimer.h: Include <stdbool.h>.
65 2012-08-22 Dan Nicolaescu <dann@gnu.org>
67 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
68 compile time tests instead of run time tests on systems that do
70 (FRAME_MAC_P): Remove leftover from deleted code.
71 * frame.c (syms_of_frame): Remove leftover from deleted code.
73 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
75 * nsterm.m (insertText:): Don't clear modifiers if code is space.
77 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
79 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
80 Otherwise, the compiler complains about (A?B:C) where B is void
81 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
82 (fontset_add): Return void, for FONTSET_ADD.
84 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
86 * alloc.c: Use bool for booleans.
87 (gc_in_progress, abort_on_gc)
88 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
89 (dont_register_blocks) [GC_MALLOC_CHECK]:
90 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

92 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
93 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
94 (mark_stack, valid_pointer_p, make_pure_string)
95 (Fgarbage_collect, survives_gc_p, gc_sweep):
96 Use bool for booleans, instead of int.
97 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
99 * alloc.c (PURE_POINTER_P):
100 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
101 * editfns.c (Fformat):
102 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
104 * fns.c (sweep_weak_table):

106 (make_pure_string, gc_in_progress, abort_on_gc):
107 * lread.c (readchar, read1):
108 * print.c (Fprin1_to_string):
109 * xdisp.c (push_message):
110 Use bool for booleans affected directly or indirectly by
113 Make recently-introduced setters macros.
114 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
115 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
116 (set_fontset_default, set_fontset_fallback): Rename from their
117 upper-case counterparts, and make them functions rather than macros.
118 This is more consistent with the other recently-introduced setters.
119 These don't need to be inline, since they're local.
121 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
123 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
124 the loop (Bug#12247).
126 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
128 * lisp.h (vcopy): Use memcpy rather than our own loop.
129 This fixes a performance regression introduced by the recent
130 addition of vcopy. This means 'vcopy' will need to be modified
131 for a copying collector, but that's OK. Also, tighten the
132 checking in the assertion.
134 2012-08-21 Eli Zaretskii <eliz@gnu.org>
136 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
137 components for RTL text (Bug#11860). Adjust X-OFFSET of each
138 non-base glyph for the width of the base character, according to
139 what x_draw_composite_glyph_string_foreground expects. Generate
140 WADJUST value according to composition_gstring_width's
141 expectations, to produce correct width of the composed character.
142 Reverse the sign of the DU offset produced by ScriptPlace.
144 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
146 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
148 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
150 Avoid direct writes to contents member of struct Lisp_Vector.
151 * lisp.h (vcopy): New function to copy data into vector.
152 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
153 * fns.c (Ffillarray): Use ASET.
154 * keyboard.c (timer_check_2): Use AREF and ASET.
155 (append_tool_bar_item, Frecent_keys): Use vcopy.
156 * lread.c (read_vector): Use ASET.
157 * msdos.c (Frecent_doskeys): Use vcopy.
158 * xface.c (Finternal_copy_lisp_face): Use vcopy.

162 2012-08-21 Martin Rudalics <rudalics@gmx.at>
164 * window.c (Fwindow_point): For the selected window always return
165 the position of its buffer's point.
166 (Fset_window_point): For the selected window always go in its
167 buffer to the specified position.
169 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
171 Setter macros for fontsets.
172 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
173 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
174 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
177 2012-08-20 Glenn Morris <rgm@gnu.org>
179 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
180 Don't assume that `ln -f' works.
182 2012-08-20 Eli Zaretskii <eliz@gnu.org>
184 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
185 and later about non-assignments with no effect. See discussion at
186 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
189 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
191 Inline setter functions for Lisp_Objects slots of struct specbinding.
192 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
195 2012-08-20 Martin Rudalics <rudalics@gmx.at>
197 * window.c (select_window): Always make selected window's buffer
200 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
202 Use AREF and ASET for docstrings of category tables.
203 * category.h (CATEGORY_DOCSTRING): Use AREF.
204 (SET_CATEGORY_DOCSTRING): Use ASET.
205 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
207 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
209 Inline setter functions for hash table members.
210 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
211 (set_hash_hash, set_hash_index): Rename with _slot suffix.
212 (set_hash_key_and_value, set_hash_index, set_hash_next)
213 (set_hash_hash): New functions.
214 * charset.c, fns.c: Adjust users.
216 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
218 Inline getter and setter functions for per-buffer values.
219 * buffer.h (per_buffer_default, set_per_buffer_default)
220 (per_buffer_value, set_per_buffer_value): New functions.
221 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
222 * buffer.c, data.c: Adjust users.
224 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
226 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
228 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
230 Rely on <config.h> + <unistd.h> to declare 'environ',
231 as gnulib does this if the system doesn't.
232 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
233 Remove declaration. MS-Windows declares it on stdlib.h which is
234 included by conf_post.h.
235 * emacs.c (environ) [DOUG_LEA_MALLOC]:
236 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
237 * vm-limit.c: Include <unistd.h>, for 'environ'.
239 * unexaix.c, unexcoff.c: Include "mem-limits.h".
240 (start_of_data): Remove decl; mem-limits.h provides it.
242 * xdisp.c (handle_invisible_prop): Make it a bit faster
243 and avoid a gcc -Wmaybe-uninitialized diagnostic.
245 2012-08-19 Chong Yidong <cyd@gnu.org>
247 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
250 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
252 * .gdbinit: Use call instead of set when calling a function in the
255 * data.c (set_internal): Don't use set_blv_found.
256 (Fkill_local_variable): Likewise.
258 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
260 * nsfont.m (ns_ascii_average_width): Ensure the string
261 ascii_printable is initialized with a null-terminated character
262 array. Otherwise, it can contain undesired extra characters.
264 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
266 port new setting code to Sun C 5.8 2005/10/13
267 * chartab.c, lisp.h (char_table_set, char_table_set_range):
268 Return void, not Lisp_Object. Otherwise, the compiler
269 complains about (A?B:C) where B is void and C is Lisp_Object
270 when compiling CHAR_TABLE_SET, due to the recent change to
271 the API of sub_char_table_set_contents.
273 2012-08-18 Chong Yidong <cyd@gnu.org>
275 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
276 for the string case (Bug#3874).

370 (kset_prefix_arg, kset_system_key_alist, kset_window_system):
371 New setter functions.

405 * intervals.c (set_interval_object): Move here from intervals.h,
406 and rename from interval_set_object.
407 (set_interval_left): Move here from intervals.h, and rename from
409 (set_interval_right): Move here from intervals.h, and rename from

446 directly-specified attributes.
447 (merge_face_ref): Recognize :font.

1104 * w32.c (init_environment): Change the default values of many
1105 environment variables in dflt_envvars[] to NULL, to avoid pushing
1106 them into environment when they were not already defined.
1107 Remove the code that deletes site-lisp subdirectories from the default
1108 value of EMACSLOADPATH, as it is no longer needed.
1109 (check_windows_init_file): Now external, not static.
1110 Use Vload_path as is, without adding anything, as this function is now
1111 called when Vload_path is already set up.
1113 * w32.h (check_windows_init_file): Add prototype.
1115 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

1147 (make_pure_float, make_pure_vector):
1148 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

1158 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
1159 Remove unnecessary pointer casts.
1160 * alloc.c (record_xmalloc): New function.
1161 * lisp.h (record_xmalloc): New decl.
1162 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
1163 more like a function. This is because the pointer cast is not
1164 needed. All uses changed.
1165 * print.c (print_string, print_error_message): Avoid length recalc.
1167 Improve fix for macroexp crash with debugging (Bug#12118).
1168 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
1169 ARRAY_MARK_FLAG when checking subscripts, because ASET is
1170 not supposed to be invoked from the garbage collector.
1171 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
1172 (gc_aset): New function, which is like ASET but can be
1173 used in the garbage collector.

1198 have the required privileges.
1199 (get_file_security_desc_by_name): Rename from
1200 get_file_security_desc.

1202 with addition of handling of symlinks and support for 'lstat'.
1203 If possible, get file's attributes and security information by
1204 handle, not by name. Produce S_IFLNK bit for symlinks, when
1205 called from 'lstat'.
1206 (stat, lstat): New functions, call 'stat_worker'.
1207 (symlink, readlink, careadlinkat): Rewritten to create and resolve
1208 symlinks when the underlying filesystem supports them.
1210 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
1212 Fix macroexp crash on Windows with debugging (Bug#12118).
1213 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
1214 checking subscripts; problem introduced with the recent
1215 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
1216 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
1217 since it's used in non-static inline functions now.
1219 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
1220 Don't assume buffer size fits in 'int'. Remove unused local.

1240 * composite.c (COMPOSITE_INLINE):
1241 * dispnew.c (DISPEXTERN_INLINE):
1242 * sysdep.c (SYSTIME_INLINE):
1243 Define to EXTERN_INLINE, so that the corresponding functions
1244 are compiled into code.

1246 (INLINE_HEADER_END): New macros.
1247 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

1267 hard-coding the path separator.
1269 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
1271 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
1272 This how ASET and AREF are supposed to work, and makes
1273 it easier to think about future improvements. See
1274 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
1275 * charset.h (set_charset_attr): New function.

1656 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
1657 (w32_kbd_patch_key, key_event): Use the codepage returned by
1658 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

1716 * alloc.c (gdb_make_enums_visible): New constant. This ports to

1765 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
1766 emacs.c, as this is a more-suitable home. Had this been done earlier
1767 the fix for 12036 would have avoided some of the problems noted in
1768 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
1769 would have been more obvious.
1770 * emacs.c: Do not include <verify.h>; no longer needed.

1779 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1780 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1781 not be usable in #if. This simplifies things.
1783 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1785 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

1790 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1791 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1792 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1793 Adjust to changes in lisp.h and emacs.c, by using
1794 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead

1796 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1797 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1798 instead of gdb_valbits.
1799 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1800 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG

2706 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2707 * nsterm.m (ns_term_init):
2708 Avoid the need for strncpy, by using build_string or
2709 make_unibyte_string directly. Use dtoastr, not snprintf.
2710 * process.c (Fmake_network_process): Diagnose service names that
2711 are too long, rather than silently truncating them or creating
2712 non-null-terminated names.
2713 (Fnetwork_interface_info): Likewise, for interface names.
2714 * sysdep.c (system_process_attributes) [GNU_LINUX]:
2715 Prefer sprintf to strncat.
2716 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

2742 Optimize pure C strings initialization.
2743 * lisp.h (make_pure_string): Fix prototype.
2744 (build_pure_c_string): New function, defined as static inline. This
2745 provides a better opportunity to optimize away calls to strlen when
2746 the function is called with compile-time constant argument.
2747 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2748 argument, adjust users accordingly. Use build_pure_c_string where
2750 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2751 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2752 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2754 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2756 Avoid calls to strlen in miscellaneous functions.
2757 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2758 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
2759 * lread.c (openp): Likewise.
2761 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2763 Avoid calls to strlen in path processing functions.
2764 * fileio.c (file_name_as_directory): Add comment. Change to add
2765 srclen argument and return the length of result. Adjust users
2767 (directory_file_name): Fix comment. Change to add srclen argument,

2769 Adjust users accordingly.
2770 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2772 2012-07-10 Glenn Morris <rgm@gnu.org>
2774 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

2779 * s/gnu.h (DATA_START): Move definitions to configure.
2781 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2782 We include usg5-4-common.h, which defines them both.
2784 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2785 O_RDONLY already includes it).
2787 Stop ns builds setting the EMACSLOADPATH environment variable.
2788 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2789 Now it does not set EMACSLOADPATH, just returns the load-path string.
2790 * nsterm.h: Update accordingly.
2791 * lread.c [HAVE_NS]: Include nsterm.h.
2792 (init_lread) [HAVE_NS]: Use ns_load_path.

2795 2012-07-09 Glenn Morris <rgm@gnu.org>
2797 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2798 since the included bsd-common.h does so.
2800 Stop ns builds setting the EMACSPATH environment variable.
2801 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2802 (ns_init_paths): Do not set EMACSPATH.
2803 * nsterm.h (ns_exec_path): Add it.
2804 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2807 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2809 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2811 * process.c (wait_reading_process_output): 'waitchannels' was unset
2812 when read_kbd || !NILP (wait_for_cell); fix this.
2814 Add GCC-style 'const' attribute to functions that can use it.
2815 * character.h (char_resolve_modifier_mask):
2816 * keyboard.h (make_ctrl_char):
2817 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

2824 Declare the dummy function with ATTRIBUTE_CONST.
2825 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2826 Add decls with ATTRIBUTE_CONST.
2828 Minor improvements to make_formatted_string.
2829 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2830 where int is good enough, as vsprintf returns an int.
2831 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2833 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2835 Use make_formatted_string to avoid double length calculation.
2836 * lisp.h (make_formatted_string): New prototype.
2837 * alloc.c (make_formatted_string): New function.
2838 * buffer.c (Fgenerate_new_buffer_name): Use it.

2842 * frame.c (make_terminal_frame, set_term_frame_name)
2843 (x_report_frame_params): Likewise.
2844 * image.c (gs_load): Likewise.
2845 * minibuf.c (get_minibuffer): Likewise.

2860 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2862 Move marker debugging code under MARKER_DEBUG.
2863 * marker.c (MARKER_DEBUG): Move marker debugging code under
2864 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2865 for bootstrap with --enable-checking (~3x slowdown reported
2866 by Juanma Barranquero <lekktu@gmail.com>).
2867 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2869 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2871 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2872 See <http://bugs.gnu.org/11825#29>.
2874 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2876 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2877 has no font, use the frame's font. (Bug#11813)
2878 (display_line): Add commentary about displaying truncation glyphs
2880 (produce_special_glyphs): Move here from term.c.
2882 * term.c (produce_special_glyphs): Move to xdisp.c.
2884 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2887 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2889 * xdisp.c (display_line): Avoid warning about implicit declaration
2892 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2894 * lisp.h: Remove empty conditional.
2896 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2898 * lread.c (load_path_check): Now static.
2900 Fix some minor --with-ns problems found by static checking.
2901 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2902 (x_set_font) [!HAVE_X_WINDOWS]:
2903 * image.c (xpm_load_image) [HAVE_NS]:
2904 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2905 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2906 Remove unused local.
2907 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2908 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2909 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2910 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2911 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2912 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2913 Fix pointer signedness problem.
2914 * xfaces.c (FRAME_X_FONT_TABLE):
2915 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2917 2012-07-07 Glenn Morris <rgm@gnu.org>
2919 * lread.c (load_path_check): New function, split from init_lread.
2920 (init_lread): Reorganize. Motivation:
2921 If EMACSLOADPATH is set, check/warn about that rather than the
2922 defaults, which we are not going to use. Hence we can remove
2923 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2924 Don't warn if site-lisp directories are missing.
2925 If not installed, start from a blank load-path, since
2926 PATH_LOADSEARCH refers to the eventual installation directories.
2928 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2930 Support truncation and continuation glyphs on GUI frames, when
2931 fringes are disabled. (Bug#11832)
2932 * xdisp.c (init_iterator): Get dimensions of truncation and
2933 continuation glyphs even if on GUI frames.
2934 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2935 or both, are absent.
2936 (start_display, move_it_in_display_line_to): Handle the case of a
2937 GUI frame without a fringe to display continuation or truncation
2939 (insert_left_trunc_glyphs): Support GUI frames: make sure
2940 truncation glyphs overwrite enough glyphs from the current line to
2941 have sufficient space in pixels.
2942 (display_line): Support truncation and continuation glyphs on GUI
2943 frames. If some spare pixels are left on the line after inserting
2944 the truncation glyphs, fill that space with a stretch glyph of a
2945 suitably computed width.
2947 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2948 produce_glyphs, to support GUI sessions.
2950 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2952 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2954 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2956 Do not require float-time's arg to fit in time_t (Bug#11825).
2957 This works better on hosts where time_t is unsigned, and where
2958 float-time is applied to the (negative) difference between two times.
2959 * editfns.c (decode_time_components): Last arg is now double *,
2960 not int *, and means to store all the result as a double, without
2961 worrying about whether the seconds part fits in time_t.
2962 All callers changed.
2963 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2964 All callers changed.
2965 (Ffloat_time): Do not fail merely because the specified time falls
2966 outside of time_t range.
2968 2012-07-07 Glenn Morris <rgm@gnu.org>
2970 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2976 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2977 Update dependencies.
2979 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2981 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2983 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

2985 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2986 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2987 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

2990 * xfont.c (compare_font_names): Redo to omit the need for casts.
2992 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2994 * xfns.c (Fx_change_window_property): Doc fix.
2995 * w32fns.c (Fx_change_window_property): Doc fix.
2997 * w32fns.c (Fx_window_property): Accept the same arguments as the
2998 X Windows version. Doc fix.
2999 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
3001 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
3002 Eli Zaretskii <eliz@gnu.org>
3004 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
3005 Windows-specific code from nt/config.nt moved here.
3006 Obsolete settings removed.
3008 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3010 * process.c: Avoid unnecessary calls to gettime.
3011 (wait_reading_process_output): Don't get the time of day
3012 when gobbling data immediately and not waiting, as there's no need
3013 for it in that case. This removes a FIXME.
3015 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
3017 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
3018 is defined (Bug#11768).
3020 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3022 Fix marker debugging code.
3023 * marker.c (byte_char_debug_check): Do not perform the check
3024 if buffer is not multibyte.
3025 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3026 Call byte_char_debug_check with correct arguments.
3028 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3030 Compile marker debugging code only if ENABLE_CHECKING is defined.
3031 * marker.c (byte_char_debug_check, count_markers):
3032 Use only if ENABLE_CHECKING is defined.
3033 (byte_debug_flag): Remove.
3034 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3035 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
3037 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3039 Avoid code repetition in marker-related functions.
3040 * marker.c (attach_marker): New function.
3041 (Fset_marker, set_marker_restricted, set_marker_both)
3042 (set_marker_restricted_both): Use it.
3043 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
3044 Consistently rename charno to charpos.
3045 (marker_position): Add eassert.
3046 (marker_byte_position): Convert to eassert.

3065 * window.c (save_window_save): Likewise.
3067 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3069 Do not use Fdelete_overlay in delete_all_overlays
3070 to avoid redundant calls to unchain_overlay.
3071 * buffer.c (drop_overlay): New function.
3072 (delete_all_overlays, Fdelete_overlay): Use it.
3073 * minibuf.c (get_minibuffer): Fix comment.
3075 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3077 Port to OpenBSD 5.1 amd64.
3078 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
3079 This is needed for OpenBSD, and should be harmless on all BSD systems.
3080 Also, include <sys/sysctl.h>, as it should be available on all
3081 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
3082 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
3083 use p_pid member, not kp_proc.pid.
3085 2012-07-06 Glenn Morris <rgm@gnu.org>
3087 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
3089 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
3091 More xmalloc and related cleanup.
3092 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
3093 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

3100 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
3102 Omit needless casts involving void * pointers and allocation.
3103 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
3104 as the former is more robust if P's type is changed.
3105 Prefer xzalloc to xmalloc + memset 0.
3106 Simplify malloc-or-realloc to realloc.
3107 Don't worry about xmalloc returning a null pointer.
3108 Prefer xstrdup to xmalloc + strcpy.
3109 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
3111 * keyboard.c (apply_modifiers_uncached): Prefer local array to
3112 alloca of a constant.
3114 2012-07-05 Eli Zaretskii <eliz@gnu.org>
3116 * xdisp.c (display_line): Fix horizontal pixel coordinates when
3117 hscroll is larger than the line width. Fixes long and futile
3118 looping inside extend_face_to_end_of_line (on a TTY) producing
3119 glyphs that are not needed and thrown away.
3121 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
3123 * marker.c (set_marker_restricted_both): Simplify by using
3126 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

3149 * xdisp.c (window_hscroll_limited): New function.
3150 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
3151 coordinates when window's hscroll is set to insanely large
3154 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
3156 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
3157 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
3159 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
3162 * lisp.h (xzalloc): New prototype. Omit needless casts.
3163 * alloc.c (xzalloc): New function. Omit needless casts.

3165 xmalloc with following memset to xzalloc.

3217 * fileio.c (time_error_value): Check the right error number.
3218 Problem reported by Troels Nielsen in
3219 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
3221 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3223 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
3224 This should be fixed in a better way; see Eli Zaretskii in
3225 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
3226 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
3228 * fileio.c (time_error_value): Rename from special_mtime.
3229 The old name's problems were noted by Eli Zaretskii in
3230 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
3232 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
3233 This variable's comment says Emacs needs at least one GDB-visible
3234 symbol of type enum pvec_type, to work around GDB problems.
3235 The symbol's value doesn't matter.
3237 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
3238 that causes compilation to fail on pre-C99 compilers.
3240 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
3242 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
3243 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
3245 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3247 * buffer.c (init_buffer_once): Fix initialization of
3248 headers for buffer_defaults and buffer_local_symbols.
3249 Reported by Juanma Barranquero <lekktu@gmail.com>.
3251 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
3253 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
3254 * lisp.h (enum pvec_type): Use fewer bits.
3255 (PSEUDOVECTOR_SIZE_BITS): New constant.
3256 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
3257 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
3258 change in pvec_type.
3259 (PSEUDOVECTOR_TYPEP): New macro.
3260 (TYPED_PSEUDOVECTORP): Use it.
3261 * fns.c (internal_equal): Adapt code to extract pvectype.

3263 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
3264 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
3265 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
3266 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
3267 (sweep_vectors): Use it. Use local var `total_bytes' instead of
3268 abusing vector->header.next.nbytes.
3269 (live_vector_p): Use PVEC_TYPE.
3270 (mark_object): Adapt code to extract pvectype. Use switch.
3272 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3274 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
3275 Tighten new eassert a bit.
3277 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3279 Fix compilation with --enable-gcc-warnings and -O1
3281 * doprnt.c (doprnt): Change type of tem to int, initialize
3282 to avoid compiler warning. Add eassert.
3283 * search.c (simple_search): Initialize match_byte to avoid
3284 compiler warning. Add eassert.
3286 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3288 Avoid weird behavior with large horizontal scrolls.
3289 Without this change, for example, large hscroll values would
3290 mess up Emacs's display on Fedora 15 x86, presumably due to
3291 overflows in int calculations in the display code.
3292 Also, if buffers had long lines, Emacs would freeze.
3293 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
3294 (set_window_hscroll): New function, containing the old guts of
3295 Fset_window_hscroll. Return the clipped value.
3296 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
3297 This avoids the need to check against PTRDIFF_MAX.
3299 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
3301 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3303 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
3305 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3307 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
3308 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
3309 since GCC 4.4.6 issues a bogus warning for them.
3311 Fix bugs in file timestamp newness comparisons.
3312 * fileio.c (Ffile_newer_than_file_p):
3313 * lread.c (Fload): Use full timestamp resolution of files,
3314 not just the 1-second resolution, so that files that are only
3315 slightly newer still count as newer.
3316 * fileio.c (Ffile_newer_than_file_p): Don't assume file
3317 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
3319 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
3321 * fileio.c: Improve handling of file time marker. (Bug#11852)
3322 (special_mtime): New function.
3323 (Finsert_file_contents, Fverify_visited_file_modtime):
3324 Use it to set special mtime values consistently.
3326 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
3328 * fileio.c (Finsert_file_contents): Properly handle st_mtime
3329 marker for non-existing file. (Bug#11852)
3331 2012-07-03 Glenn Morris <rgm@gnu.org>
3333 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
3334 and did not make it into globals.h).
3336 2012-07-03 Tom Tromey <tromey@redhat.com>
3338 * window.c (Fset_window_margins, Fset_window_fringes)
3339 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
3340 * textprop.c (Fprevious_property_change): No longer static.
3341 * syntax.c (Fsyntax_table_p): No longer static.
3342 * process.c (Fget_process, Fprocess_datagram_address): No longer

3363 * intervals.h: Remove EXFUNs.
3364 * fontset.h: Remove EXFUN.

3369 * w32term.h: Remove EXFUNs.
3370 * window.h: Remove EXFUNs.

3372 * xterm.h: Remove EXFUN.
3374 2012-07-03 Glenn Morris <rgm@gnu.org>
3376 * lisp.h (Frandom): Make it visible to C.
3377 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
3378 buffer for invisible buffers. (Bug#1229)
3380 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3382 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
3383 values which aren't power of 2.
3384 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
3385 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
3388 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
3390 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
3392 * alloc.c (mark_object): Revert part of last patch to use `switch'.
3394 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3396 * alloc.c (allocate_vector_block): Remove redundant
3397 calls to mallopt if DOUG_LEA_MALLOC is defined.
3398 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
3399 avoid calls to mallopt if zero_vector is returned.
3401 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3403 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
3404 is enabled, avoid dereferencing NULL current_sblock if
3407 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3409 Cleanup basic buffer management.
3410 * buffer.h (struct buffer): Change layout to use generic vector
3411 marking code. Fix some comments. Change type of 'clip_changed'
3412 to bitfield. Remove unused #ifndef old.
3413 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
3414 (GET_OVERLAYS_AT): Fix indentation.
3415 (for_each_per_buffer_object_at): New macro.

3419 * alloc.c (allocate_buffer): Adjust to match new layout of
3420 struct buffer. Fix comment.
3421 (mark_overlay): New function.

3424 (mark_object): Use it. Adjust marking of misc objects
3425 and related comments.
3427 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
3429 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
3430 wrapper that is not needed because the wrapped code is a no-op (zero
3431 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
3432 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
3434 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
3436 * alloc.c (mark_buffer): Simplify. Remove prototype.
3437 (mark_object): Add comment. Reorganize marking of vector-like
3438 objects. Use CHECK_LIVE for all vector-like objects except buffers
3439 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
3440 Avoid redundant calls to mark_vectorlike for bool vectors.
3442 2012-06-30 Glenn Morris <rgm@gnu.org>
3444 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3446 * epaths.in (PATH_SITELOADSEARCH): New.
3447 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3448 This is rather than relying on --enable-locallisppath elements
3449 having "site-lisp" in their names. (Bug#10208#25, 11658)
3451 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3453 * w32proc.c (sys_select): Accept and ignore one more argument.
3455 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3457 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3458 (pselect) [!MS_DOS]: Redirect to sys_select.
3460 * sysdep.c: Don't include dos.h and dosfns.h.
3462 * process.c (sys_select):
3463 * msdos.c (sys_select): Accept one more argument and ignore it.
3465 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3466 adapt data types and code to that.
3469 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3470 which clashes with the gnulib function of the same name.
3472 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3474 * font.c (font_style_to_value, font_style_symbolic)
3475 (font_prop_validate_style): Add type checks for values in
3478 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3480 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3483 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3485 * xdisp.c (try_window_id): Undo last change.
3487 * w32.c (getwd): Adjust commentary about startup_dir.
3488 (init_environment): Always call sys_access, even in non-MSVC
3489 builds. Don't chdir to the directory of the Emacs executable.
3490 This undoes code from 1997 which was justified by the need to
3491 "avoid conflicts when removing and renaming directories". But its
3492 downside was that every relative file name was being interpreted
3493 relative to the directory of the Emacs executable, which can never
3494 be TRT. In particular, it broke sys_access when called with
3495 relative file names.
3496 (sys_access): Map GetLastError to errno.
3498 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3500 * window.h (struct window): Change type of 'fringes_outside_margins'

3504 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3507 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3509 * gnutls.c (emacs_gnutls_handshake):
3510 Add QUIT to make the loop interruptible.
3512 2012-06-29 Glenn Morris <rgm@gnu.org>
3514 * charset.c (init_charset): Make lack of etc/charsets fatal.
3516 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3518 * editfns.c (region_limit): Fix type mismatch.
3520 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3522 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3523 undefined. Convert from xassert to eassert.
3524 * nsmenu.m: Convert from xassert to eassert.
3525 * nsterm.m: Likewise.
3527 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3529 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3531 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3533 Avoid integer overflow on scroll-left and scroll-right.
3534 * window.c (HSCROLL_MAX): New macro.
3535 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3536 overflow when requested scroll falls outside ptrdiff_t range.
3538 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3540 * window.h (struct window): Change type of 'hscroll',
3541 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3542 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3543 Adjust users accordingly.
3544 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3545 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3546 from EMACS_INT to ptrdiff_t.
3547 (make_window): Omit redundant initialization.
3549 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3551 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
3553 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3555 * window.h (struct window): Change type of 'use_time' and
3556 'sequence_number' from Lisp_Object to int.

3565 enabled with --enable-checking=[all,glyphs] configure option.
3566 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3567 adjust comments accordingly.

3618 avoid GCC warning about unused macro.
3620 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3622 * alloc.c (allocate_string): Omit intervals initialization.
3623 * alloc.c (make_uninit_multibyte_string): Initialize intervals
3624 as in make_pure_string and make_pure_c_string.
3626 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3628 * alloc.c (allocate_string): Fix last change.
3630 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

3680 * alloc.c: Remove build_string.
3681 * lisp.h: Define build_string as static inline. This provides
3682 a better opportunity to optimize away calls to strlen when the
3683 function is called with compile-time constant argument.
3684 * image.c (imagemagick_error): Convert to build_string.
3685 * w32proc.c (sys_spawnve): Likewise.
3686 * xterm.c (x_term_init): Likewise.
3688 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3690 Use sprintf return value instead of invoking strlen on result.
3691 In the old days this wasn't portable, since some sprintf
3692 implementations returned char *. But they died out years ago and
3693 Emacs already assumes sprintf returns int.
3694 Similarly for float_to_string.
3695 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
3696 * ccl.c (ccl_driver):
3697 * character.c (string_escape_byte8):

3700 * print.c (print_object):
3701 * xdisp.c (message_dolog):
3702 * xfns.c (syms_of_xfns):
3703 Use sprintf or float_to_string result to avoid need to call strlen.
3704 * data.c (Fnumber_to_string):
3705 Use make_unibyte_string, since the string must be ASCII.
3706 * lisp.h, print.c (float_to_string): Now returns int length.
3707 * term.c (produce_glyphless_glyph):
3708 Use sprintf result rather than recomputing it.
3710 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3711 * Makefile.in (ALL_CFLAGS):
3712 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
3713 * gmalloc.c, regex.c: Include <config.h> unconditionally.
3715 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3717 * dispextern.h (xstrcasecmp): Define to library function
3718 strcasecmp if available.
3719 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
3721 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

3734 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
3736 * gtkutil.c (get_utf8_string): Remove redundant assignment.
3737 sprintf already null-terminates its output.
3739 * xfns.c (x_window): Remove redundant cast.
3741 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3743 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
3744 `const char *' to `char *' to avoid compiler warning.
3746 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3748 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
3749 instead of truncating it to 63 (admittedly a generous limit).
3751 * process.c: Fix spelling and caps in comments.
3753 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
3755 * emacs.c (setpgrp): Remove definition, unused.

3800 No need for separate decl merely because of _Noreturn.
3801 * sound.c (sound_warning, parse_sound):
3802 Remove unnecessary forward decls.
3804 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3806 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
3807 * lisp.h (WAIT_READING_MAX): New macro.
3808 * dispnew.c (Fsleep_for, sit_for):
3809 * keyboard.c (kbd_buffer_get_event):
3810 * process.c (Faccept_process_output):
3811 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3812 This improves on the previous patch, which introduced a bug
3813 when time_t is unsigned and as wide as intmax_t.
3814 See <http://bugs.gnu.org/9000#51>.
3816 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3818 * dispnew.c (sit_for, Fsleep_for):
3819 * keyboard.c (kbd_buffer_get_event):

3832 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
3833 Privately reported by Herbert J. Skuhra.
3834 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
3836 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
3837 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3839 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3841 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
3842 last argument of make_unibyte_string.
3844 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
3845 language ID in the event parameters.
3847 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3848 event.code, not the obscure "character set ID".
3850 2012-06-23 Chong Yidong <cyd@gnu.org>
3852 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
3854 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3856 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

3871 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
3872 Privately reported by Herbert J. Skuhra.
3873 [__FreeBSD__]: Remove "*/" typo after "#include".

3879 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3881 Support higher-resolution time stamps (Bug#9000).
3882 The time stamps are only nanosecond-resolution at the C level,
3883 since that's the best that any real-world system supports now.
3884 But they are picosecond-resolution at the Lisp level, as that's
3885 easy, and leaves room for future OS improvements.
3887 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3890 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3891 Don't get current time unless it's needed.
3893 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3894 now provides it if it's absent.
3895 (start_atimer): Port to higher-res time stamps.
3896 Check for time stamp overflow. Don't get current time more
3897 often than is needed.
3899 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3900 Include systime.h, not time.h.
3901 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3903 * dired.c: Include stat-time.h.
3904 (Ffile-attributes): File times now have higher resolution.
3906 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3907 (struct image): Timestamp now has higher resolution.
3909 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3910 has at least microseconds now. All uses removed.
3911 (update_frame, update_single_window, update_window, update_frame_1)
3912 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3913 (duration_to_sec_usec): Remove; no longer needed.
3915 * editfns.c (time_overflow): Now extern.
3916 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3917 (float-time, Fformat_time_string, Fcurrent_time_string)
3918 (Fcurrent_time_zone): Accept and generate higher-resolution
3920 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3921 (decode_time_components, lisp_seconds_argument): New functions.
3922 (make_time): Now static.
3923 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3924 Report an error if the time is invalid, rather than having the caller
3927 * fileio.c: Include <stat-time.h>
3928 (Fcopy_file): Copy higher-resolution time stamps.
3929 Prefer to set the time stamp via a file descriptor if that works.
3930 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3931 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3932 (Fvisited_file_modtime, Fset_visited_file_modtime):
3933 Support higher-resolution time stamps.
3935 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3937 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3939 * image.c (prepare_image_for_display, clear_image_cache)
3940 (lookup_image): Port to higer-resolution time stamps.
3942 * keyboard.c (start_polling, bind_polling_period):
3943 Check for time stamp overflow.
3944 (read_char, kbd_buffer_get_event, timer_start_idle)
3945 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3946 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3947 Port to higher-resolution time stamps. Do not assume time_t is signed.
3948 (decode_timer): New function. Timers are now vectors of length 9,
3949 not 8, to accommodate the picosecond component.
3950 (timer_check_2): Use it.
3952 * nsterm.m (select_timeout, timeval_subtract): Remove.
3953 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3954 as they're a bit more accurate and handle overflow better.
3955 (ns_select): Change prototype to be compatible with pselect.
3956 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3957 * nsterm.h (ns_select): Adjust prototype.
3959 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3960 us-resolution time stamps.
3961 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3963 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3965 * lisp.h (time_overflow): New decl.
3966 (wait_reading_process_output): First arg is now intmax_t, not int,
3967 to accommodate larger waits.
3969 * process.h (struct Lisp_Process.read_output_delay):
3970 Now counts nanoseconds, not microseconds.
3971 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3973 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3974 (wait_reading_process_output):
3975 Port to ns-resolution time stamps.
3976 (Faccept_process_output, wait_reading_process_output):
3977 Check for time stamp overflow. Do not assume time_t is signed.
3978 (select_wrapper): Remove; we now use pselect.
3979 (Fprocess_attributes): Now generates ns-resolution time stamps.
3981 * sysdep.c: Include utimens.h. Don't include utime.h
3982 or worry about struct utimbuf; gnulib does that for us now.
3983 (gettimeofday): Remove; gnulib provides a substitute.
3984 (make_timeval): New function.
3985 (set_file_times): Now sets ns-resolution time stamps.
3986 New arg FD; all uses changed.
3987 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3988 (system_process_attributes):
3989 Now returns ns-resolution time stamp. All uses changed.
3990 Check for time stamp overflow.
3992 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3993 provides a substitute now.
3995 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3996 since it guarantees struct timespec.
3997 (EMACS_TIME): Now struct timespec, so that we can support
3998 ns-resolution time stamps.
3999 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
4000 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
4001 (EMACS_USECS): Remove.
4002 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
4003 so multiply the arg by 1000 before storing it.
4004 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
4006 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
4007 Port to ns-resolution time stamps.
4008 (EMACS_TIME_NEG_P): Remove; replaced by....
4009 (EMACS_TIME_SIGN): New macro.
4010 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
4011 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
4012 (set_file_times, make_time, lisp_time_argument): Adjust signature.
4013 (make_timeval, make_lisp_time, decode_time_components): New decls.
4014 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
4015 that it mishandled time_t overflow. You can't compare by subtracting!
4016 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
4017 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
4019 * term.c: Include <sys/time.h>.
4020 (timeval_to_Time): New function, for proper overflow wraparound.

4023 * undo.c (record_first_change): Support higher-resolution time stamps
4025 (Fprimitive_undo): Use them when restoring time stamps.
4027 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
4028 (w32_get_internal_run_time):
4029 Port to higher-resolution Emacs time stamps.
4030 (ltime): Now accepts single 64-bit integer, as that's more convenient
4033 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
4035 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
4036 for compatibility with pselect. Support ns-resolution time stamps.
4038 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
4040 * xselect.c (wait_for_property_change, x_get_foreign_selection):
4041 Check for time stamp overflow, and support ns-resolution time stamps.
4043 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
4044 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
4045 (timeval_subtract): Remove; no longer needed.
4046 (XTflash, XTring_bell, x_wait_for_event):
4047 Port to ns-resolution time stamps. Don't assume time_t is signed.
4049 2012-06-22 Chong Yidong <cyd@gnu.org>
4051 * xdisp.c (x_consider_frame_title): Revert last change.
4053 2012-06-22 Eli Zaretskii <eliz@gnu.org>
4055 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
4056 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
4057 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
4058 staticidx goes up to 1597 out of 1600 = 0x640.)
4060 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
4062 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
4063 Otherwise, the umask might be mistakenly 0 while handling input signals.
4065 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
4067 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

4073 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
4074 access to `contents' member of Lisp_Vector objects with AREF and ASET
4077 2012-06-19 Chong Yidong <cyd@gnu.org>
4079 * frame.c (delete_frame): When selecting a frame on a different
4080 text terminal, do not alter the terminal's top-frame.

4083 frame's selected window and its terminal's top-frame.
4084 (unwind_format_mode_line): Restore them.
4085 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
4087 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
4088 since tty frames can be explicitly named.
4089 (prepare_menu_bars): Likewise.
4091 * term.c (Ftty_top_frame): New function.
4093 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
4095 Port byte-code-meter to modern targets.
4096 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
4097 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
4098 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
4099 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
4100 (METER_1, METER_2): Simplify.
4102 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
4104 * data.c (Fdefalias): Return `symbol' (bug#11686).
4106 2012-06-18 Martin Rudalics <rudalics@gmx.at>
4108 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
4109 gets killed during executing of this function (Bug#11665).
4110 Try to always return Qt when the buffer has been actually killed.
4111 (Vkill_buffer_query_functions): In doc-string say that functions
4112 run by this hook should not change the current buffer.

4330 code works fine either way, and efficiency is not a concern here,
4331 as the union type is for debugging, not for production.
4332 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
4333 Use an inline function on all platforms when using the union type,
4334 since this is simpler and 'static inline' can be used portably
4336 (LISP_INITIALLY_ZERO): New macro.
4337 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

4478 * doprnt.c (doprnt): Truncate multibyte char correctly.
4479 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4480 would mishandle a string argument "Xc" if X was a multibyte
4481 character of length 2: it would truncate after X's first byte
4482 rather than including all of X.

4565 and 'double' in a couple of places.
4567 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4569 * xdisp.c (handle_stop): Detect whether we have overlay strings
4570 loaded by testing it->current.overlay_string_index to be
4571 non-negative, instead of checking whether n_overlay_strings is
4572 positive. (Bug#11587)

4584 maybe_unify_char, which was the cause of relocation of buffer text
4587 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4589 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4590 for the duration of call to load_charset, to avoid problems with
4591 callers of maybe_unify_char that access buffer text through C
4594 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4595 decrement the inhibition flag, instead of just setting or
4598 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4600 Remove obsolete '#define static' cruft.
4601 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
4602 This #undef was "temporary" in 2000; it is no longer needed
4603 now that '#define static' has gone away.
4604 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4605 (gray_bitmap_bits): Remove; no longer needed.
4606 All uses replaced with definiens.
4607 * xterm.c: Include "bitmaps/gray.xbm".
4609 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4611 Clean up __executable_start, monstartup when --enable-profiling.
4612 The following changes affect the code only when profiling.
4613 * dispnew.c (__executable_start): Rename from safe_bcopy.
4614 Define only on platforms that need it.
4615 * emacs.c: Include <sys/gmon.h> when profiling.
4616 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
4617 (__executable_start): Remove decl, since lisp.h does it now.
4618 (safe_bcopy): Remove decl; no longer has that name.
4619 (main): Coalesce #if into single bit of code, for simplicity.
4620 Cast pointers to uintptr_t, since standard libraries want integers
4622 * lisp.h (__executable_start): New decl.
4624 2012-05-31 Glenn Morris <rgm@gnu.org>
4626 * image.c (Fimagemagick_types): Doc fix.
4628 2012-05-30 Jim Meyering <meyering@redhat.com>
4630 * callproc.c (Fcall_process_region): Include directory component

4645 * lread.c (read1): Tiny simplification.
4647 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4649 Do not create empty overlays with the evaporate property (Bug#9642).
4650 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4651 Bug#9642, but explicitly check that the buffer the overlay would
4652 be moved to is live and rearrange lines to make sure that errors
4653 will not put the overlay in an inconsistent state.
4654 (Fdelete_overlay): Cosmetics.
4656 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4658 * w32term.c (my_bring_window_to_top): New function.
4659 (x_raise_frame): Use handle returned by DeferWindowPos, which
4660 could be different from the original one.

4664 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4665 by calling BringWindowToTop.
4667 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4668 (WM_EMACS_END): Increase by one.
4670 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4672 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4673 This avoids undefined behavior that might cause the eassert
4674 to not catch an out-of-range value.
4676 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4678 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4679 Update dependencies.
4681 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4683 * bidi.c (bidi_mirror_char): Fix last change.
4685 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
4687 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
4688 when referring to sectname field in printf format.
4690 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4692 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4693 Only r_alloc_inhibit_buffer_relocation needed to be added;
4694 the others were already declared.
4696 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4697 before checking whether it's out of range. Put the check inside
4699 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4701 2012-05-27 Ken Brown <kbrown@cornell.edu>
4703 * callproc.c (Fcall_process): Restore a line that was accidentally
4704 commented out in the 2011-02-13 change (bug#11547).
4706 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4708 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4709 defined on ralloc.c.
4711 * buffer.c [REL_ALLOC]: Remove prototypes of
4712 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4713 they are now on lisp.h.
4715 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4717 * search.c (search_buffer): Use it to inhibit relocation of buffer
4718 text while re_search_2 is doing its job, because re_search_2 is
4719 passed C pointers to buffer text. (Bug#11519)
4721 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4724 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4725 state after an additional call to move_it_in_display_line_to, keep
4726 the values of it->max_ascent and it->max_descent found for the
4728 (pos_visible_p): Revert the comparison against bottom_y to what it
4729 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4732 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4734 Fix coding-related core dumps with gcc -ftrapv.
4735 The code was computing A - B, where A and B are pointers, and B is
4736 random garbage. This can lead to core dumps on platforms that
4737 have special pointer registers, and it also leads to core dumps on
4738 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4739 A - B only when B is initialized properly.
4740 * coding.c (coding_set_source, coding_set_destination): Return void.
4741 (coding_change_source, coding_change_destinations): New functions,
4742 with the old behaviors of coding_set_source and coding_set_destination.
4743 All callers that need an offset changed to use these new functions.
4745 2012-05-26 Glenn Morris <rgm@gnu.org>
4747 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4749 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4751 Extend mouse support on W32 text-mode console.
4752 * xdisp.c (draw_row_with_mouse_face):
4753 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4755 * w32console.c: Include window.h.
4756 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4758 (initialize_w32_display): Initialize mouse-highlight data.
4760 * w32inevt.c: Include termchar.h and window.h.
4761 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4762 moves, call note_mouse_highlight. If help_echo changed, call
4763 gen_help_event to produce help-echo message in the echo area.
4764 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4767 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4769 * lread.c (read1): Simplify slightly to avoid an overflow warning
4770 with GCC 4.7.0 on x86-64.
4772 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4774 * bidi.c (bidi_mirror_char): Revert last change: an int is
4775 definitely wide enough here.
4777 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4779 Fix integer width and related bugs (Bug#9874).
4780 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):

4787 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4789 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4790 (allocate_pseudovector):
4791 Use int, not EMACS_INT, where int is wide enough.
4792 (inhibit_garbage_collection, Fgarbage_collect):
4793 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4794 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4795 int might not be wide enough.
4796 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4797 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

4799 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4800 (bidi_level_of_next_char, bidi_move_to_visually_next):
4801 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4802 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4803 (Fkill_buffer, Fset_buffer_major_mode)

4807 (overlay_strings, recenter_overlay_lists)
4808 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4809 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4810 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4811 (Foverlay_recenter, last_overlay_modification_hooks_used)
4812 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4813 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4814 (validate_region): Omit unnecessary test for b <= e,
4815 since that's guaranteed by the previous test.
4816 (adjust_overlays_for_delete): Avoid pos + length overflow.
4817 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4818 (report_overlay_modification):
4819 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4820 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4821 Omit pointer cast, which isn't needed anyway, and doesn't work
4822 after the EMACS_INT -> ptrdiff_t change.
4823 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4824 * buffer.h: Adjust decls to match defn changes elsewhere.

4828 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4829 not int, to avoid needless 32-bit limit on 64-bit hosts.
4830 (exec_byte_code): Use tighter memory-full test, one that checks
4831 for alloca overflow. Don't compute the address of the object just
4832 before an array, as that's not portable. Use EMACS_INT, not
4833 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4834 * callint.c (Fcall_interactively):
4835 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4836 * callproc.c (call_process_kill, Fcall_process):
4837 Don't assume pid_t fits into an Emacs fixnum.

4840 (call_process_cleanup, Fcall_process, delete_temp_file)
4841 (Fcall_process_region):
4842 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4843 (Fcall_process): Simplify handling of volatile integers.

4846 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4847 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4848 (casify_object): Avoid integer overflow when overallocating buffer.
4849 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4850 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4851 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4852 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4853 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4854 integers are now checked earlier. All uses replaced with XINT.
4856 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4857 For CCL_MapSingle, check that content and value are in int range.
4858 (ccl_driver, Fregister_code_conversion_map):
4859 Check that Vcode_version_map_vector is a vector.
4860 (resolve_symbol_ccl_program): Check that vector header is in range.
4861 Always copy the vector, so that we can check its contents reliably
4862 now rather than having to recheck each instruction as it's being
4863 executed. Check that vector words fit in 'int'.
4864 (ccl_get_compiled_code, Fregister_ccl_program)
4865 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4866 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4867 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4868 contents are in range.
4869 (Fccl_execute_on_string): Check that status is in range.
4870 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4871 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4872 Accept and return EMACS_INT, not int, because callers can pass values
4874 (c_string_width, strwidth, lisp_string_width, chars_in_text)

4877 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4878 (string_escape_byte8, Fget_byte):
4879 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4880 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4881 avoid mishandling large integers.
4882 * character.h: Adjust decls to match defn changes elsewhere.

4891 (Fdefine_charset_internal): Check ranges here, more carefully.
4892 Don't rely on undefined behavior with signed left shift overflow.
4893 Don't assume unsigned int fits into fixnum, or that fixnum fits
4894 into unsigned int. Don't require max_code to be a valid fixnum;
4895 that's not true for gb10830 4-byte on a 32-bit host. Allow
4896 invalid_code to be a cons, for the same reason. Require code_offset
4897 to be a character. Avoid int overflow if max_char is close
4899 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4900 this is intended anyway and avoids some undefined behavior.
4901 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4902 INDEX_TO_CODE_POINT, as that's what it expects.
4903 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4904 * charset.h (DECODE_CHAR): Return int, not unsigned;
4905 this is what was intended anyway, and it avoids undefined behavior.
4906 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4907 integer-overflow issues.
4908 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4909 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4910 where the argument is EMACS_INT, and this behavior is not intended.
4911 * chartab.c (Fmake_char_table, Fset_char_table_range)
4912 (uniprop_get_decoder, uniprop_get_encoder):
4913 Don't assume fixnum fits in int.
4914 * cmds.c (move_point): New function, that does the gist of
4915 Fforward_char and Fbackward_char, but does so while checking
4916 for integer overflow more accurately.
4917 (Fforward_char, Fbackward_char): Use it.
4918 (Fforward_line, Fend_of_line, internal_self_insert)
4919 (internal_self_insert):
4920 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4921 Fix a FIXME, by checking for integer overflow when calculating
4922 target_clm and actual_clm.

4954 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4955 (consume_chars): Rewrite to not calculate an address outside buffer.
4956 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
4957 Don't access memory outside of the args array.
4958 (Fdefine_coding_system_internal): Check for charset-id overflow.
4959 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4960 result of ENCODE_CHAR.

4978 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4979 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
4980 Do not attempt to compute the address of the object just before a
4981 buffer; this is not portable.
4983 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4984 (Faset): Use int, not EMACS_INT, where int is wide enough.
4985 (Fstring_to_number): Don't assume fixnums fit in int.

5726 and there's something on it->stack, call set_iterator_to_next to
5727 proceed with what's on the stack, instead of returning zero.
5728 (set_iterator_to_next): If called at the end of a Lisp string,
5729 proceed to consider_string_end without incrementing string
5730 position. Don't increment display vector index past the end of
5731 the display vector. (Bug#11417)
5732 (pos_visible_p): Don't report a position visible when move_it_to
5733 stopped at the last line of window, which happens to be scanned
5734 backwards by the bidi iteration. (Bug#11464)
5736 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5738 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5739 and right-margin display specs even if the spec is invalid or we
5740 are on a TTY, and thus unable to display on the fringes.
5741 That's because the text with the property will not be displayed anyway,
5742 so we need to signal to the caller that this is a "replacing"
5743 display spec. This fixes display when the spec is invalid or we
5746 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5748 * unexaix.c (make_hdr): Fix typo in prototype.
5749 This bug broke the build on AIX. Problem reported by Gilles Pion.
5751 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5753 * keyboard.c (kbd_buffer_get_event): Read special events also in
5754 batch mode. (Bug#11415)
5756 2012-05-12 Glenn Morris <rgm@gnu.org>
5758 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5760 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5762 * lisp.mk (lisp): Add newcomment.elc.
5764 2012-05-12 Glenn Morris <rgm@gnu.org>
5766 * Makefile.in (MKDIR_P): New, set by configure.
5767 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5769 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5771 Remove unused function hourglass_started.
5772 * dispextern.h (hourglass_started):
5773 * w32fns.c (hourglass_started):
5774 * xdisp.c (hourglass_started): Remove.
5776 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5778 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5779 Update dependencies.
5781 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5783 * xgselect.c (xg_select): Put maxfds+1 into a var.
5784 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5786 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5788 2012-05-10 Dave Abrahams <dave@boostpro.com>
5790 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5791 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5793 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5795 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5796 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5797 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5798 Initialize xd_registered_buses.
5800 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5802 Untag more efficiently if USE_LSB_TAG.
5803 This is based on a proposal by YAMAMOTO Mitsuharu in
5804 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5805 For an admittedly artificial (nth 8000 longlist) benchmark on
5806 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5807 Emacs's overall text size by 1%.
5808 * lisp.h (XUNTAG): New macro.
5809 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5810 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5811 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5812 * eval.c (Fautoload):
5813 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5814 * frame.h (XFRAME): Use XUNTAG.
5816 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5817 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5818 Remove unportable assumptions about print widths of types like
5820 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5821 intptr_t when converting between pointer and integer, to avoid GCC
5822 warnings about wrong width.
5824 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5826 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5827 stack for each reader_thread, instead of defaulting to 8MB
5828 determined by the linker. This avoids failures in creating
5829 subprocesses on Windows 7, see the discussion in this thread:
5830 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5832 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5834 Fix up display of the *Minibuf-0* buffer in the mini window.
5835 * keyboard.c (read_char): Don't clear the echo area if there's no
5837 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5838 contents of *Minibuf-0*) if there's no message displayed in its stead.
5840 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5842 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5845 2012-05-06 Chong Yidong <cyd@gnu.org>
5847 * lisp.mk (lisp): Update.
5849 2012-05-05 Jim Meyering <meyering@redhat.com>
5851 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5853 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5855 * data.c (PUT_ERROR): New macro.
5856 (syms_of_data): Use it. Add new error type `user-error'.
5857 * undo.c (user_error): New function.
5858 (Fprimitive_undo): Use it.
5859 * print.c (print_error_message): Adjust print style for `user-error'.
5860 * keyboard.c (user_error): New function.
5861 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5863 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5865 Do not limit current-time-string to years 1000..9999.
5866 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5867 (Fcurrent_time_string): Support any year that is supported by the
5868 underlying localtime representation. Don't use asctime, as it
5869 has undefined behavior for years outside the range -999..9999.
5871 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5873 Fix race conditions involving setenv, gmtime, localtime, asctime.
5874 Without this fix, interrupts could mess up code that uses these
5875 nonreentrant functions, since setting TZ invalidates existing
5876 tm_zone or tzname values, and since most of these functions return
5877 pointers to static storage.
5878 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5879 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5880 Grow the critical sections to include not just invoking
5881 localtime/gmtime, but also accessing these functions' results
5882 including their tm_zone values if any, and any related TZ setting.
5883 (format_time_string): Last arg is now struct tm *, not struct tm **,
5884 so that the struct tm is saved in the critical section.
5885 All callers changed. Simplify allocation of initial buffer, partly
5886 motivated by the fact that memory allocation needs to be outside
5887 the critical section.
5889 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5891 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5892 with RESET_INTERVAL.
5894 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5895 Remove duplicated buffer name initialization.
5897 2012-05-02 Jim Meyering <jim@meyering.net>
5899 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5901 * xfns.c (x_window): Use xstrdup (Bug#11375).
5903 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5905 * xdisp.c (pos_visible_p): If already at a newline from the
5906 display string before the 'while' loop, don't walk back the glyphs
5907 from it3.glyph_row. Solves assertion violation when the display
5908 string begins with a newline (egg.el). (Bug#11367)
5910 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5912 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5915 2012-05-01 Glenn Morris <rgm@gnu.org>
5917 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5918 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5919 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5920 All were removed before 23.1.
5922 * dispnew.c: Remove HAVE_LIBNCURSES test;
5923 it is always true on relevant platforms.
5925 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5926 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5928 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5930 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5932 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5933 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5936 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5938 Do not avoid creating empty evaporating overlays (Bug#9642).
5939 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5940 That is, do not delete an evaporating overlay if it becomes
5941 empty after its bounds are adjusted to fit within its buffer.
5942 This fix caused other problems, and I'm reverting it until we get
5943 to the bottom of them.
5945 2012-04-27 Chong Yidong <cyd@gnu.org>
5947 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5949 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5951 * xdisp.c (pos_visible_p): If the window start position is beyond
5952 ZV, start the display from buffer beginning. Prevents assertion
5953 violation in init_iterator when the minibuffer window is scrolled
5956 * window.c (window_scroll_pixel_based): Likewise.
5958 2012-04-27 Chong Yidong <cyd@gnu.org>
5960 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5962 2012-04-27 Glenn Morris <rgm@gnu.org>
5964 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5965 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5967 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5969 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5970 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5972 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5974 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5975 display element, check also the underlying string or buffer
5976 character. (Bug#11341)
5978 * w32menu.c: Include w32heap.h.
5979 (add_menu_item): If the call to AppendMenuW (via
5980 unicode_append_menu) fails, disable Unicode menus only if we are
5981 running on Windows 9X/Me.
5983 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5985 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5986 (xgetint): Add missing shift for LSB tags.
5988 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5990 * keyboard.c (read_char): Don't wipe echo area for select window
5991 events: These might get delayed via `mouse-autoselect-window'
5994 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5996 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5997 manipulation of :loaded-from data.
5999 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
6001 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
6002 now a cons (bug#11311).
6004 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
6006 Do not create empty overlays with the evaporate property (Bug#9642).
6007 * buffer.c (Fmove_overlay): Delete an evaporating overlay
6008 if it becomes empty after its bounds are adjusted to fit within
6009 its buffer. Without this fix, in a nonempty buffer (let ((o
6010 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
6011 yields an empty overlay that has the evaporate property, which is
6012 not supposed to happen.
6014 Fix minor GTK3 problems found by static checking.
6015 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
6016 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6017 (struct _EmacsFixedClass, emacs_fixed_get_type):

6025 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
6026 (EMACS_FIXED_GET_CLASS): Remove; unused.
6027 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
6029 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
6030 Problem reported by Juanma Barranquero for Windows -Wunused-function.
6032 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6034 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
6035 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
6036 (__malloc_size_t, __malloc_ptrdiff_t):
6037 Remove. All uses removed, replaced by the definiens if needed,
6038 since we can assume C89 or better now.
6039 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
6040 (protect_malloc_state, align, get_contiguous_space)
6041 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

6047 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
6048 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
6049 Define using prototypes, not old style.
6050 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
6051 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
6052 (align): Don't assume that signed integer overflow wraps around.
6053 Omit unused local var.
6054 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
6055 (_free_internal_nolock, memalign, mallochook, reallochook):
6056 Omit no-longer-needed casts.
6057 (valloc): Use getpagesize, not __getpagesize.

6059 (struct hdr): The 'magic' member is now size_t, not unsigned long.
6061 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
6063 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

6108 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6110 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
6111 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
6112 Do not assume ptrdiff_t is the same width as 'int'.
6114 * alloc.c: Handle unusual debugging option combinations.
6115 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
6116 since the two debugging options are incompatible.
6117 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
6119 (mem_init, mem_insert, mem_insert_fixup):
6120 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

6127 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6129 * sysdep.c [__FreeBSD__]: Minor cleanups.
6130 (list_system_processes, system_process_attributes) [__FreeBSD__]:
6131 Use Emacs indenting style more consistently. Avoid some casts.
6132 Use 'double' consistently rather than mixing 'float' and 'double'.
6134 2012-04-21 Eduard Wiebe <usenet@pusto.de>
6136 * sysdep.c (list_system_processes, system_process_attributes):
6137 Add implementation for FreeBSD (Bug#5243).

6150 * print.c (print_preprocess): Only check print_depth if print-circle
6152 (print_object): Check for cycles even when print-circle is nil and

6170 (set_cursor_from_row): If called for a mode-line or header-line
6171 row, return zero immediately.
6172 (try_cursor_movement): If inside continuation line, don't back up
6173 farther than the first row after the header line, if any.
6174 Don't consider the header-line row as "partially visible", even if
6175 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

6191 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
6192 -Wunused-result, -Wunused-variable. This should go away once
6193 the Emacs and Gnulib regex code is merged.

6212 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
6213 New extern decls, to avoid calling undeclared functions.
6214 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
6215 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
6216 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
6217 (NEED_MEM_INSERT): New macro.
6218 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
6219 Remove one incorrect comment and fix another.

6225 (r_alloc_sbrk): Now static.
6227 Improve ralloc.c interface checking.
6228 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

6232 [REL_ALLOC]: ... to here, to check interface.
6233 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
6234 Remove decls. This fixes an "It stinks!".
6236 * alloc.c (which_symbols): Fix alignment issue / type clash.
6238 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
6240 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
6241 (struct Lisp_Misc_Any): Likewise.

6253 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
6254 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
6255 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
6256 * s/netbsd.h, s/sol2-6.h:
6257 Remove definition of GC_MARK_STACK, since the default now works.
6258 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
6259 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
6260 no longer the default.
6261 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
6263 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
6265 * lread.c (lisp_file_lexically_bound_p):

6273 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
6275 * nsterm.m (constrainFrameRect): Always constrain when there is only
6276 one screen (Bug#10962).
6278 2012-04-13 Ken Brown <kbrown@cornell.edu>
6280 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.

6286 2012-04-11 Daniel Colascione <dancol@dancol.org>
6288 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
6289 against is gone. It's better to use vfork now so that when Cygwin
6290 gains a new, working vfork, we use it automatically (bug#10398).
6292 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
6294 * window.c (save_window_save): Obey window-point-insertion-type.

6310 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
6312 * w32.c (w32_delayed_load): Record the full path of the library
6313 being loaded (bug#10424).
6315 2012-04-09 Glenn Morris <rgm@gnu.org>
6317 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
6318 not just in the obarray, before snarfing them. (Bug#11036)
6320 * Makefile.in ($(leimdir)/leim-list.el):
6321 Pass EMACS rather than BUILT_EMACS.

6330 Add convenience `GNUTLS_LOG2i' macro.
6332 * gnutls.c (gnutls_log_function2i): Convenience log function.
6333 (emacs_gnutls_read): Use new log functions,
6334 `gnutls_handshakes_tried' process member, and

6345 * minibuf.c (Fread_variable): Callers changed.
6347 2012-04-09 Eli Zaretskii <eliz@gnu.org>
6349 * xdisp.c (set_cursor_from_row): If the display string appears in
6350 the buffer at position that is closer to point than the position
6351 after the display string, display the cursor on the first glyph of
6352 the display string. Fixes cursor display when a 'display' text
6353 property immediately follows invisible text. (Bug#11094)
6355 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
6357 composite.c: use 'double' consistently
6358 * composite.c (get_composition_id): Use 'double' consistently
6359 instead of converting 'float' to 'double' and vice versa; this is
6360 easier to understand and avoids a GCC warning.
6362 2012-04-09 Glenn Morris <rgm@gnu.org>
6364 * Makefile.in: Generate leim-list with bootstrap-emacs, in
6365 preparation for dumping it with emacs. (Bug#4789)

6387 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
6388 (mark_memory): Mark Lisp_Objects only if pointers might hide in
6389 objects, as mark_maybe_pointer will catch them otherwise.
6390 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
6391 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
6393 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
6395 Fix typo that broke non-Windows builds.
6396 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

6400 Support building on MS-Windows with libxml2.
6402 * makefile.w32-in (OBJ2): Add xml.$(O).

6406 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
6407 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
6408 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
6409 [!WINDOWSNT]: New macros.
6410 (init_libxml2_functions, libxml2_loaded_p): New functions.
6411 (parse_region): Call fn_xmlCheckVersion instead of using the macro
6412 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
6413 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
6414 Calls xmlCleanupParser only if libxml2 was loaded (or statically
6416 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
6417 Call init_libxml2_functions before calling libxml2 functions.
6418 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
6420 * emacs.c: Don't include libxml/parser.h.
6421 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
6422 xmlCleanupParser directly.
6424 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
6426 2012-04-07 Eli Zaretskii <eliz@gnu.org>
6428 * indent.c (Fvertical_motion): If there is a display string at
6429 point, use it.vpos to compute how many lines to backtrack after
6430 move_it_to point. (Bug#11133)

6434 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
6435 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
6436 about subtle differences between FETCH_CHAR* and STRING_CHAR*
6437 macros related to unification of CJK characters. For the details,
6438 see the discussion following the message here:
6439 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6441 2012-04-04 Chong Yidong <cyd@gnu.org>
6443 * keyboard.c (Vdelayed_warnings_list): Doc fix.
6445 2012-04-01 Eli Zaretskii <eliz@gnu.org>
6447 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

6455 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6457 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6458 position we get to after a call to move_it_to fails the
6459 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6460 only if we wind up in a string from display property. (Bug#11063)
6462 * window.c (Fdelete_other_windows_internal): Invalidate the row
6463 and column information about mouse highlight, so that redisplay
6464 restores it after reallocating the glyph matrices. (Bug#7464)
6466 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6467 string comes from a `display' text property, use the buffer
6468 position of that property as if we actually saw that position in
6470 (move_it_by_lines): Remove the assertion that
6471 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6472 violated when there's a before-string at the beginning of a line.
6475 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6477 * xdisp.c (append_space_for_newline): If the default face was
6478 remapped, use the remapped face for the appended newline.
6479 (extend_face_to_end_of_line): Use the remapped default face for
6480 extending the face to the end of the line.
6481 (display_line): Call extend_face_to_end_of_line when the default
6482 face was remapped. (Bug#11068)
6484 2012-03-29 Eli Zaretskii <eliz@gnu.org>
6486 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

6510 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
6512 2012-03-25 Kenichi Handa <handa@m17n.org>
6514 * dispextern.h (struct glyph): Change the bit length of
6515 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6517 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6519 * s/ms-w32.h (tzname): Include time.h before redirecting to
6520 _tzname. Fixes the MSVC build. (Bug#9960)
6522 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
6524 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6527 * xterm.c (XTread_socket): Only modify handling_signal if
6528 !SYNC_INPUT. (Bug#11080)
6530 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6532 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6533 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6534 when fetching a multibyte character consumes more bytes than
6535 CHAR_BYTES returns, due to unification of CJK characters in
6536 string_char. (Bug#11073)
6538 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6540 * process.c (wait_reading_process_output): Handle pty disconnect

6552 2012-03-21 Chong Yidong <cyd@gnu.org>
6554 * xfaces.c (Vface_remapping_alist): Doc fix.
6556 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6558 * w32proc.c (Fw32_set_console_codepage)
6559 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

6570 it fit in a valid range (Bug#11003).
6572 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6574 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6575 that is not from display property, accept the row as a "cursor
6576 row" if one of the string's character has a non-nil `cursor'
6577 property. Fixes cursor positioning when there are newlines in
6578 overlay strings, e.g. in icomplete.el. (Bug#11035)
6580 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6582 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

6586 * eval.c (inhibit_lisp_code): Rename from
6587 inhibit_window_configuration_change_hook; move from window.c.
6589 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6590 * window.c (run_window_configuration_change_hook)
6591 (syms_of_window): Callers changed.
6593 2012-03-11 Chong Yidong <cyd@gnu.org>
6595 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6597 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
6599 2012-03-10 Chong Yidong <cyd@gnu.org>

6602 is visible (Bug#10955).
6604 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
6606 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6608 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6610 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6611 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6614 2012-03-03 Glenn Morris <rgm@gnu.org>
6616 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6618 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6620 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6621 position past the first glyph_row that ends at ZV. (Bug#10902)
6622 (redisplay_window, next_element_from_string): Fix typos in
6624 (redisplay_window): Pass to move_it_vertically the margin in
6625 pixels, not in screen lines.
6627 2012-03-02 Glenn Morris <rgm@gnu.org>
6629 * buffer.c (buffer-list-update-hook): Doc fix.
6631 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6633 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6634 push_it before setting up the iterator for the first overlay
6635 string, even if we have an empty string loaded.
6636 (next_overlay_string): If there's an empty string on the iterator
6637 stack, pop the stack. (Bug#10903)
6639 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6641 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6642 Suggested by Stefan Monnier in
6643 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6644 * alloc.c (widen_to_Lisp_Object): New static function.
6645 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6646 and widening them to Lisp_Objects. This would work even if
6647 USE_LSB_TAG is defined and wide integers are used, which might
6648 happen in a future version of Emacs.
6650 2012-02-25 Chong Yidong <cyd@gnu.org>
6652 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6655 * xselect.c (Fx_selection_exists_p): Doc fix.
6656 (x_clipboard_manager_save_all): Print an informative message
6657 before saving to clipboard manager.
6659 2012-02-24 Chong Yidong <cyd@gnu.org>

6689 when computing $valmask.
6691 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6692 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6693 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6694 It's useless in that case, and it can cause problems on hosts
6695 that allocate halves of EMACS_INT values separately.
6696 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6697 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6698 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6699 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6700 it avoids undefined behavior on hosts where shifting right by more
6701 than the word width has undefined behavior.

6749 highlight (Bug#9904).
6751 2012-02-12 Glenn Morris <rgm@gnu.org>

6783 * buffer.c (Fbuffer_local_variables)
6784 (buffer_lisp_local_variables): Handle unbound vars correctly;

6787 2012-02-07 Glenn Morris <rgm@gnu.org>
6789 * image.c (Fimagemagick_types): Doc fix.

6827 * character.c (char_width): Return EMACS_INT, not int.
6828 (char_width, c_string_width): Check for overflow when
6829 computing the width; this is possible now that individual
6830 characters can have unbounded width. Problem introduced

7489 to 4 (xorl, subq, cmpq, setbe).
7490 * alloc.c (pure): Always extern now, since that's the

7503 behave as if the cursor position were at the window margin.
7505 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7506 and the cursor position is out of bounds, behave as if the cursor

7537 * dispnew.c (verify_row_hash): Call row_hash for computing the
7538 hash code of a row, instead of duplicating code from xdisp.c.
7540 * dispextern.h (row_hash): Add prototype.
7542 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
7544 * frame.c (delete_frame): Don't delete the terminal when the last

7576 * image.c (imagemagick_load_image): Fix typo.
7578 2011-11-14 Eli Zaretskii <eliz@gnu.org>
7580 * xdisp.c (display_line): Move the call to

7654 by removing the "extern"s.
7655 * intervals.c (adjust_intervals_for_insertion)
7656 (adjust_intervals_for_deletion): Undo previous change,
7657 making these static again.

7684 2011-11-07 Martin Rudalics <rudalics@gmx.at>
7686 * window.h: Declare delete_all_child_windows instead of

7699 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7700 This is also needed for porting to any host where GC_MARK_STACK is
7701 not GC_MAKE_GCPROS_NOOPS.
7702 (which_symbols): Use it.
7704 2011-11-07 Kenichi Handa <handa@m17n.org>

7717 * xmenu.c (cleanup_widget_value_tree): New function.
7718 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

7723 Fix some portability problems with 'inline'.
7724 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
7725 (window_box_width, window_box_left, window_box_left_offset)
7726 (window_box_right, window_box_right_offset): Declare extern.
7727 Otherwise, these inline functions do not conform to C99 and
7728 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7729 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7730 * intervals.c (adjust_intervals_for_insertion)
7731 (adjust_intervals_for_deletion): Now extern, because otherwise the
7732 extern inline functions 'offset_intervals' couldn't refer to it.
7733 (static_offset_intervals): Remove.
7734 (offset_intervals): Rewrite using the old contents of
7735 static_offset_intervals. The old version didn't conform to C99
7736 because an extern inline function contained a reference to an
7737 identifier with static linkage.
7739 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>

7759 (Fwindow_vscroll): Doc fix.
7760 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
7761 argument, since it makes no sense to pass a live window and for

7792 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
7793 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
7794 Move terminal->reference_count++ just before making the frame official

7908 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7909 so that this new function doesn't get optimized away by a
7910 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
7912 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
7914 * frame.h (MOUSE_HL_INFO): Remove excess parens.

7935 Not clear what it was for, and it causes various bugs. (Bug#9839)
7937 2011-10-28 Eli Zaretskii <eliz@gnu.org>
7939 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
7940 possible random value that matches one of those tested as
7941 condition to clear the mouse face.
7943 2011-10-28 Chong Yidong <cyd@gnu.org>

7970 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
7972 (w32font_open_internal, compute_metrics):
7973 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
7974 instead of calling the "wide" APIs directly.
7976 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
7978 * w32.h (syms_of_w32font): Add prototype.

7989 * process.c (make_process): Set gnutls_state to NULL.
7991 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
7992 non-NULL, regardless of GNUTLS_INITSTAGE.
7993 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
7994 an error. Set process slots as soon as we allocate them.

8040 current character, check also for next_en_type being WEAK_EN.
8041 (bidi_resolve_weak): Don't enter the expensive loop if the current
8042 position is before next_en_pos. Record the bidi type of the first
8043 non-ET, non-BN character we find, in addition to its position.
8044 (bidi_level_of_next_char): Invalidate next_en_type when
8045 next_en_pos is over-stepped.
8047 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
8049 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
8050 * editfns.c: Rewrite current-time-zone so that it invokes
8051 the equivalent of (format-time-string "%Z") to get the time zone name.
8052 This fixes a bug when the time zone name contains characters that
8053 need converting from the system time locale to Emacs internal format.
8054 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
8055 that patch fixed format-time-string to do the conversion, but
8056 I forgot to fix current-time-zone.
8057 (format_time_string): New function, containing most of
8058 what Fformat_time_string used to contain.
8059 (Fformat_time_string): Rewrite in terms of format_time_string.
8060 This doesn't change this function's behavior.
8061 (current-time-zone): Rewrite to use format_time_string.
8062 This fixes the bug reported by Michael Schierl in
8063 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
8064 Jason Rumney's 2007-06-07 change worked around this bug, but
8066 * systime.h (tzname, timezone): Remove no-longer-used declarations.
8068 2011-10-19 Eli Zaretskii <eliz@gnu.org>
8070 * xdisp.c (start_display): If the character at POS is displayed
8071 via a display vector, reset IT->current.dpvec_index to zero.
8072 (try_window_reusing_current_matrix): If a line ends in a display
8073 vector or the next line starts in a display vector, continue
8074 redrawing the window even though the character position of
8075 start_row was reached.
8078 2011-10-18 Chong Yidong <cyd@gnu.org>
8080 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
8081 with nobreak-char-display too.
8083 2011-10-18 Eli Zaretskii <eliz@gnu.org>
8085 Fix part 3 of bug#9771.
8086 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
8087 (bidi_resolve_neutral): Don't enter the expensive loop looking for
8088 non-neutral characters if the current character is a paragraph
8089 separator (a.k.a. Newline). This avoids running the same
8090 expensive loop twice, once when we consume the preceding newline
8091 and the other time when the line actually needs to be displayed.
8092 Avoid the loop when we see neutrals on the base embedding level
8093 following a character whose directionality is the same as the
8094 paragraph's. This avoids running the expensive loop when a line
8095 ends in a long sequence of neutrals, like control characters.
8096 Add assertion against STRONG_AL type. Slightly rearrange code
8097 that determines the type of a neutral given the first non-neutral
8099 (bidi_level_of_next_char): Set next_en_pos to zero when
8100 invalidating its info.
8102 2011-10-17 Eli Zaretskii <eliz@gnu.org>
8104 * xdisp.c (push_display_prop): Determine whether to record string
8105 or buffer position by IT->string, not by IT->method. Allow
8106 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
8107 (move_it_vertically_backward): Don't look for character position
8108 immediately after the newline when in a continuation line.
8111 2011-10-15 Martin Rudalics <rudalics@gmx.at>
8113 * window.c (coordinates_in_window): Rewrite and delabelize
8114 vertical border check. (Bug#5357) (Bug#9618)
8116 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
8118 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
8119 errors in XSetWindowBorder (bug#9310).
8121 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
8123 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
8124 avoid crash when xmalloc overrun checking is enabled.
8126 2011-10-13 Eli Zaretskii <eliz@gnu.org>
8128 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
8129 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
8130 cursor motion with <left> and <right> arrow keys.
8132 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
8133 some callers set that themselves.
8135 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8137 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
8138 display string and the previous row comes from the same string and
8139 is empty. (Bug#9739) (Bug#9738)
8141 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
8143 * doc.c (get_doc_string): Encode file name (bug#9735).
8145 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8147 * bidi.c (bidi_level_of_next_char):
8148 * xdisp.c (get_visually_first_element): Remove old incorrect
8149 comments regarding the Unicode Line Separator character.
8151 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
8153 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
8155 * alloc.c (Fgc_status): Do not access beyond zombies array
8156 boundary if nzombies > MAX_ZOMBIES.
8157 * alloc.c (dump_zombies): Add missing format specifier.
8159 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
8161 * xdisp.c (set_cursor_from_row): Simplify conditionals,
8162 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
8164 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
8165 Some packages use them to denote characters with modifiers.
8167 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
8169 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
8170 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
8171 matching a pp-number. Rename parameter var to var1.
8173 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
8175 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
8177 2011-10-08 Glenn Morris <rgm@gnu.org>
8179 * callint.c (Fcall_interactively): Give a more explicit error for the
8180 'c' case with a non-character input. (Bug#8479)
8182 2011-10-08 Eli Zaretskii <eliz@gnu.org>
8184 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
8186 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
8187 lines that are hscrolled on the left.
8189 * dispnew.c (buffer_posn_from_coords): Account for a possible
8190 presence of header-line. (Bug#4426)
8192 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
8194 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
8195 Don't advertise functionality which we discourage or doesn't work.
8197 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
8199 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
8200 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
8201 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
8202 this makes Emacs dump core during garbage collection on rare
8203 occasions. sizeof is obviously inferior to offsetof here, so
8204 stick with offsetof.
8205 (GC_POINTER_ALIGNMENT): New macro.
8206 (mark_memory): Omit 3rd (offset) arg; caller changed.
8207 Don't assume EMACS_INT alignment is the same as pointer alignment.
8209 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
8211 * keyboard.c (read_key_sequence_remapped): New var.
8212 (read_key_sequence): Compute remapping in the right buffer.
8213 (command_loop_1): Use read_key_sequence's remapping directly.
8215 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
8217 * dired.c (file_name_completion): Don't expand file name.
8218 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
8219 before checking file name handler.
8221 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
8222 they've been requested explicitly (bug#9591).
8224 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
8226 * keymap.c (Fsingle_key_description): Use make_specified_string
8227 instead of build_string to build string from push_key_description.
8230 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8232 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
8233 This fixes a Y2038 bug on 64-bit hosts.
8234 * buffer.c (reset_buffer):
8235 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
8236 (Fclear_buffer_auto_save_failure):
8237 Use 0, not -1, to represent an unset failure time, since time_t
8238 might not be signed.
8240 Remove dependency on glibc malloc internals.
8241 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8242 Move back here from lisp.h, but with their new implementations.
8243 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8244 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
8245 * charset.c (charset_table_init): New static var.
8246 (syms_of_charset): Use it instead of xmalloc. This removes a
8247 dependency on glibc malloc internals. See Eli Zaretskii's comment in
8248 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
8249 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8250 Move back to alloc.c.
8251 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8252 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
8254 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
8256 * nsterm.m (windowDidResize): Call x_set_window_size only when
8257 ns_in_resize is true. Otherwise set pixelwidth/height and
8258 call change_frame_size (Bug#9628).
8260 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8262 Port --enable-checking=all to Fedora 14 x86-64.
8263 * charset.c (syms_of_charset): Also account for glibc malloc's
8264 internal overhead when calculating the initial malloc maximum.
8266 Port --enable-checking=all to Fedora 14 x86.
8267 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8269 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
8270 (overrun_check_realloc, overrun_check_free):
8271 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
8272 That way, xmalloc returns a properly-aligned pointer even if
8273 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
8274 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
8275 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
8276 into account when calculating the initial malloc maximum.
8277 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8278 Move here from alloc.c, so that charset.c can use it too.
8279 Properly align; the old code wasn't right for common 32-bit hosts
8280 when configured with --enable-checking=all.
8281 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8282 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
8284 2011-09-29 Eli Zaretskii <eliz@gnu.org>
8286 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
8289 2011-09-28 Eli Zaretskii <eliz@gnu.org>
8291 * xdisp.c (compute_display_string_end): If there's no display
8292 string at CHARPOS, return -1.
8294 * bidi.c (bidi_fetch_char): When compute_display_string_end
8295 returns a negative value, treat the character as a normal
8296 character not covered by a display string. (Bug#9624)
8298 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
8300 * lread.c (Fread_from_string): Fix typo in docstring.
8302 2011-09-27 Eli Zaretskii <eliz@gnu.org>
8304 * xdisp.c (handle_invisible_prop): If invisible text ends on a
8305 newline, reseat the iterator instead of bidi-iterating there one
8306 character at a time. (Bug#9610)
8307 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
8308 TO_CHARPOS if the bidi iterator is at base embedding level.
8310 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
8312 * lread.c (readevalloop): Use correct code for NBSP.
8313 (read1): Likewise. (Bug#9608)
8315 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
8317 * dbusbind.c (Fdbus_register_signal): When service is not
8318 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
8320 2011-09-25 Glenn Morris <rgm@gnu.org>
8322 * buffer.c (truncate-lines): Doc fix.
8324 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
8326 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
8327 (Fset_window_next_buffers): Doc fix.
8329 2011-09-24 Glenn Morris <rgm@gnu.org>
8331 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
8333 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
8335 Fix minor problems found by static checking.
8336 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
8337 * indent.c (Fvertical_motion): Fix == vs = typo.
8339 2011-09-24 Eli Zaretskii <eliz@gnu.org>
8341 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
8342 Default value is now t. Doc fix.
8344 * indent.c (Fvertical_motion): Compute and apply the overshoot
8345 logic when moving up, not only when moving down. Fix the
8346 confusing name and values of the it_overshoot_expected variable;
8347 logic changes accordingly. (Bug#9254) (Bug#9549)
8349 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
8350 CHARPOS is covered by a display string which includes newlines.
8351 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
8352 is covered by a display string with embedded newlines.
8354 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
8356 * dbusbind.c (Fdbus_register_signal): Add match rule to
8357 Vdbus_registered_objects_table. (Bug#9581)
8358 (Fdbus_register_method, Vdbus_registered_objects_table):
8361 2011-09-24 Jim Meyering <meyering@redhat.com>
8363 do not ignore write error for any output size
8364 The previous change was incomplete.
8365 While it makes emacs --batch detect the vast majority of stdout
8366 write failures, errors were still ignored whenever the output size is
8367 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
8368 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
8369 && echo FAIL: ignored write error
8370 FAIL: ignored write error
8371 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
8372 && echo FAIL: ignored write error
8373 FAIL: ignored write error
8374 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
8376 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
8378 * emacs.c (Fkill_emacs): In noninteractive mode exit
8379 non-successfully if a write error occurred on stdout. (Bug#9574)
8381 2011-09-21 Eli Zaretskii <eliz@gnu.org>
8383 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
8386 * dispextern.h (struct it): Update the comment documenting what
8389 2011-09-20 Eli Zaretskii <eliz@gnu.org>
8391 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
8392 a display string, extend search for cursor position to end of row.
8393 (find_row_edges): If the row ends in a newline from a display
8394 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
8395 Handle the case of a display string with multiple newlines.
8396 (Fcurrent_bidi_paragraph_direction): Fix search for previous
8397 non-empty line. Fixes confusing cursor motion with arrow keys at
8398 the beginning of a line that starts with whitespace.
8400 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8402 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
8405 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
8407 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
8410 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8412 * xdisp.c (display_line): Record maximum and minimum buffer
8413 positions even if no glyphs were produced (e.g., by a zero-width
8414 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
8415 buffer positions that will be removed from the glyph row because
8417 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
8418 column is beyond frame width: don't subtract 1 "pixel" when
8419 computing width of the stretch.
8420 (reseat_at_next_visible_line_start): Undo the change made on
8421 2011-09-17 that saved paragraph information and restored it after
8422 the call to `reseat'. (Bug#9545)
8424 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8426 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
8427 and turn window cursor on if cleared (Bug#9415).
8429 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
8431 * search.c (boyer_moore): Take unibyte characters from pattern
8432 literally. (Bug#9458)

8438 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
8440 Fix minor problem found by static checking.
8441 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8442 initialized, to pacify gcc -Wuninitialized.
8444 * fileio.c: Report proper errno when syscall falls.
8445 (Finsert_file_contents): Save and restore errno,
8446 so that report_file_error outputs the correct diagnostic.
8447 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8449 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8451 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
8453 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8455 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
8456 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
8458 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8460 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8461 about the current paragraph and restore it after the call to reseat.
8463 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
8464 (bidi_find_paragraph_start): Search back for paragraph beginning
8465 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
8466 (bidi_move_to_visually_next): Only trigger paragraph-related
8467 computations when the last character is a newline or at EOB, not
8468 just any NEUTRAL_B. (Bug#9470)
8470 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
8471 truncated lines if point is covered by a display string. (Bug#9524)
8473 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8475 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8476 (cons_to_x_long): New function.
8477 (lisp_data_to_selection_data): Use it. Correct the test for
8478 short-versus-long data; it was negated. Break out of vector
8479 loop, for efficiency, when a long datum is discovered.
8481 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8483 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8485 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8487 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
8488 GCC PR/17406) by declaring this function with external scope.
8490 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8492 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

8495 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
8497 * editfns.c (Fformat): Correctly handle text properties on "%%".

8507 of TAB characters in a composition.
8509 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
8511 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8512 This occurs when processing a multibyte format.
8513 Problem reported by Wolfgang Jenker.
8515 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8517 * xdisp.c (try_cursor_movement): Only check for exact match if
8518 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8520 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8522 Remove unused external symbols.
8523 * dispextern.h (calc_pixel_width_or_height): Remove decl.
8524 * xdisp.c (calc_pixel_width_or_height): Now static.
8525 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
8526 * indent.c (check_display_width):
8527 * w32term.c: Fix comment to match code.
8528 * xterm.c, xterm.h (x_catching_errors): Remove.
8530 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8532 * xselect.c: Use signed conversions more consistently (Bug#9498).
8533 (selection_data_to_lisp_data): Assume incoming selection data are
8534 signed integers, not unsigned. This is to be consistent with
8535 outgoing selection data, which was modified to use signed integers
8536 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8537 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8538 expects long, not unsigned long.
8540 2011-09-14 Eli Zaretskii <eliz@gnu.org>
8542 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
8543 computation of loop end. Reported by Johan Bockgård
8546 2011-09-13 Chong Yidong <cyd@stupidchicken.com>

8550 2011-09-12 Eli Zaretskii <eliz@gnu.org>
8552 * indent.c (compute_motion): Process display vector front to back
8553 rather than the other way around. (Bug#2496)
8555 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8557 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.

8561 * minibuf.c (Fread_from_minibuffer): Doc fix.
8563 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8565 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8566 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8568 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8570 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8571 value for non-existent files.
8573 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8575 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8576 set its "size" to -1. This will set the modtime_size field of
8577 the corresponding buffer to -1, which is what
8578 verify-visited-file-modtime expects for files that do not exist.
8581 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8583 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8585 * lisp.h: ... from here. push_key_description is no longer
8586 defined in keyboard.c, so its declaration should not be in
8587 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8588 logically belongs with push_key_description.
8590 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8592 * buffer.h: Include <sys/types.h> instead of <time.h>.
8593 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8594 Problem reported by Herbert J. Skuhra.
8596 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8598 * xml.c (parse_region): Make the parsing work for
8599 non-comment-starting XML files again (bug#9144).
8601 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8603 * image.c (gif_load): Fix calculation of bottom and right corner.
8606 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8608 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8609 redisplay in small windows.
8611 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8613 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8615 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8617 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8618 Operate on live windows only.
8620 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8622 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8624 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8626 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8627 only under bidi iteration.
8629 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8631 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8633 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8635 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8636 Without this fix, the command to link temacs failed due to an
8637 undefined symbol __builtin_isnan. This is because
8638 /usr/include/iso/math_c99.h #defines isnan(x) to
8639 __builtin_isnan(x), but the bundled gcc, which identifies itself
8640 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8642 * floatfns.c (isnan): #undef, and then #define to a clone of
8644 (Fisnan): Always define, since it's always available now.
8645 (syms_of_floatfns): Always define isnan at the Lisp level.
8647 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8649 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8651 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8653 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8654 The previous code assumed that file offsets (off_t values) fit in
8655 EMACS_INT variables, which is not true on typical 32-bit hosts.
8656 The code messed up by falsely reporting buffer overflow in cases
8657 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8658 when "big" contains more than 2**29 bytes, even though this
8659 inserts just one byte and does not overflow the buffer.
8660 (Finsert_file_contents): Store file offsets as off_t
8661 values, not as EMACS_INT values. Check for overflow when
8662 converting between EMACS_INT and off_t. When checking for
8663 buffer overflow or for overlap, take the offsets into account.
8664 Don't use EMACS_INT for small values where int suffices.
8665 When checking for overlap, fix a typo: ZV was used where
8666 ZV_BYTE was intended.
8667 (Fwrite_region): Don't assume off_t fits into 'long'.
8668 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8670 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8672 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8674 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8676 sprintf-related integer and memory overflow issues (Bug#9412).
8678 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8679 (esprintf, exprintf, evxprintf): New functions.
8680 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8681 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8682 (modify_event_symbol): Do not assume that the length of
8683 name_alist_or_stem is safe to alloca and fits in int.
8684 (Fexecute_extended_command): Likewise for function name and binding.
8685 (Frecursion_depth): Wrap around reliably on integer overflow.
8686 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8687 since some callers pass EMACS_INT values.
8688 (Fsingle_key_description): Don't crash if symbol name contains more
8689 than MAX_ALLOCA bytes.
8690 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8691 (get_minibuffer): Arg is now EMACS_INT, not int.
8692 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8693 (esprintf, exprintf, evxprintf): New decls.
8694 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8696 * dbusbind.c (signature_cat): New function.
8697 (xd_signature, Fdbus_register_signal):
8698 Do not overrun buffer; instead, report string overflow.
8700 * dispnew.c (add_window_display_history): Don't overrun buffer.
8701 Truncate instead; this is OK since it's just a log.
8703 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8704 even if the time zone offset is outlandishly large.
8705 Don't mishandle offset == INT_MIN.
8707 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8708 when creating daemon; the previous buffer-overflow check was incorrect.
8710 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8711 which has the guts of the old verror function.
8713 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8714 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8716 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8717 (font_unparse_xlfd): Don't blindly alloca long strings.
8718 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8719 fits in int, when using sprintf. Use single snprintf to count
8720 length of string rather than counting it via multiple sprintfs;
8721 that's simpler and more reliable.
8722 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8723 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8724 sprintf, in case result does not fit in int.
8726 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8727 (fontset_from_font): Print it.
8729 * frame.c (tty_frame_count): Now printmax_t, not int.
8730 (make_terminal_frame, set_term_frame_name): Print it.
8731 (x_report_frame_params): In X, window IDs are unsigned long,
8732 not signed long, so print them as unsigned.
8733 (validate_x_resource_name): Check for implausibly long names,
8734 and don't assume name length fits in 'int'.
8735 (x_get_resource_string): Don't blindly alloca invocation name;
8736 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8739 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8740 (xg_check_special_colors, xg_set_geometry):
8741 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8743 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8744 Use esprintf, not sprintf, in case result does not fit in int.
8746 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8747 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8748 it as a large positive number.
8749 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8750 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8752 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8753 in case result does not fit in int.
8755 * print.c (float_to_string): Detect width overflow more reliably.
8756 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8757 buffer overrun. Don't assume list length fits in 'int'. Treat
8758 print length of 0 as 0, not as infinity; to be consistent with other
8759 uses of print length in this function. Don't overflow print length
8760 index. Don't assume hash table size fits in 'long', or that
8761 vectorlike size fits in 'unsigned long'.
8763 * process.c (make_process): Use printmax_t, not int, to format
8764 process-name gensyms.
8766 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8768 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8769 to avoid potential buffer overrun.
8771 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8772 if X resource line is longer than 512 bytes.
8774 * xfns.c (x_window): Make sprintf buffer a bit bigger
8775 to avoid potential buffer overrun.
8777 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8779 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8781 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8783 Integer overflow fixes for scrolling, etc.
8784 Without these, Emacs silently mishandles large integers sometimes.
8785 For example, "C-u 4294967297 M-x recenter" was treated as if
8786 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8788 * xdisp.c (try_window_id): Check Emacs fixnum range before
8789 converting to 'int'.
8791 * window.c (window_scroll_line_based, Frecenter):
8792 Check that an Emacs fixnum is in range before assigning it to 'int'.
8793 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8794 values converted from Emacs fixnums.
8795 (Frecenter): Don't wrap around a line count if it is out of 'int'
8796 range; instead, treat it as an extreme value.
8797 (Fset_window_configuration, compare_window_configurations):
8798 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8800 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8801 that can exceed INT_MAX. Check that EMACS_INT value is in range
8802 before assigning it to the (possibly-narrower) index.
8803 (match_limit): Don't assume that a fixnum can fit in 'int'.
8805 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8808 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8809 (Fvertical_motion): Don't wrap around LINES values that don't fit
8810 in 'int'. Instead, treat them as extreme values. This is good
8811 enough for windows, which can't have more than INT_MAX lines anyway.
8813 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8815 * Require libxml/parser.h to avoid compilation warning.
8817 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8819 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8820 since this reportedly can destroy thread storage.
8822 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8824 * syntax.c (find_defun_start): Update all cache variables if
8825 exiting early (Bug#9401).
8827 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8829 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8831 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8832 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8833 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8835 * term.c (tty_append_glyph): New function.
8836 (produce_stretch_glyph): Static function and its prototype deleted.
8838 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8841 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8843 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8844 when checking :margin (Bug#9390).
8845 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8846 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8847 so that the name doesn't mislead. All uses changed.
8849 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8851 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8854 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8856 * xdisp.c (move_it_to): Don't bail out early when reaching
8857 position beyond to_charpos, if we are scanning backwards.
8858 (move_it_vertically_backward): When DY == 0, make sure we get to
8859 the first character in the line after the newline.
8861 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8863 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8864 (ccl_driver): Do not generate an out-of-range pointer.
8865 (Fccl_execute_on_string): Remove unnecessary check for
8866 integer overflow, noted by Stefan Monnier in
8867 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8868 Remove a FIXME that didn't need fixing.
8869 Simplify the newly-introduced buffer reallocation code.
8871 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8873 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8875 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8877 Integer and memory overflow issues (Bug#9196).
8879 * doc.c (get_doc_string): Rework so that
8880 get_doc_string_buffer_size is the actual buffer size, rather than
8881 being 1 less than the actual buffer size; this makes xpalloc more
8884 * image.c (x_allocate_bitmap_record, cache_image):
8885 * xselect.c (Fx_register_dnd_atom):
8886 Simplify previous changes by using xpalloc.
8888 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8889 since either will do and ptrdiff_t is convenient with xpalloc.
8891 * charset.c (charset_table_size)
8892 (struct charset_sort_data.priority): Now ptrdiff_t.
8893 (charset_compare): Don't overflow if priorities differ greatly.
8894 (Fsort_charsets): Don't assume list length fits in int.
8895 Check for size-calculation overflow when allocating sort data.
8896 (syms_of_charset): Allocate an initial charset table that is
8897 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8899 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8901 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8902 The actual value is always <= INT_MAX, and leaving it unsigned made
8903 overflow checking harder.
8905 * dispextern.h (struct glyph_matrix.rows_allocated)
8906 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8907 with xpalloc. The values are still always <= INT_MAX.
8909 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8911 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8912 (SAFE_NALLOCA): New macro.
8914 * region-cache.c (struct boundary.pos, find_cache_boundary)
8915 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8916 (set_cache_region, invalidate_region_cache)
8917 (revalidate_region_cache, know_region_cache, region_cache_forward)
8918 (region_cache_backward, pp_cache):
8919 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8920 so that ptrdiff_t * can be passed to xpalloc.
8921 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8922 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8923 (pp_cache): Don't assume cache_len fits in int.
8924 * region-cache.h: Adjust extern decls to match.
8926 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8927 EMACS_INT, since either will do, for xpalloc.
8929 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8930 (xnmalloc, xnrealloc, xpalloc): New functions.
8932 * bidi.c (bidi_shelve_header_size): New constant.
8933 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8934 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8936 * bidi.c (bidi_cache_shrink):
8937 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8939 Don't update size of array until after memory allocation succeeds,
8940 because xmalloc/xrealloc may not return.
8941 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8942 now that we have proper integer overflow checking.
8943 (record_overlay_string, overlay_strings): Catch overflows when
8944 calculating size of overlay_str_buf.
8946 * callproc.c (Fcall_process): Check for size overflow when
8947 calculating size of args2.
8948 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8949 Normally we prefer signed values, but sticking with ptrdiff_t would
8950 require adding more-complicated checks.
8952 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8953 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8954 Redo buffer-overflow calculations to avoid integer overflow.
8955 Add a FIXME comment where memory seems to be over-allocated.
8957 * character.c (Fstring): Check for size-calculation overflow.
8959 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8960 unnecessary integer overflow. Check for size overflow.
8961 (encode_coding_object): Don't update size until xmalloc succeeds.
8963 * composite.c (get_composition_id): Check for overflow in glyph
8964 length calculations.
8966 Integer and memory overflow fixes for display code.
8967 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8968 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8969 (scrolling_window): Check for overflow in size calculations.
8970 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8971 Don't assume glyph table len fits in int.
8972 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8973 (row_table_size): Now ptrdiff_t, not int.
8974 (scrolling_window): Avoid overflow in size calculations.
8975 Don't update size until allocation succeeds.
8976 * fns.c (concat): Check for overflow in size calculations.
8977 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8978 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8979 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8981 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8982 (get_doc_string): Check for size calculation overflow.
8983 Don't update size until allocation succeeds.
8984 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8985 EMACS_INT, where ptrdiff_t will do.
8986 (Fsubstitute_command_keys): Check for string overflow.
8988 * editfns.c (set_time_zone_rule): Don't assume environment length
8990 (message_length): Now ptrdiff_t, not int.
8991 (Fmessage_box): Don't update size until allocation succeeds.
8992 Don't assume message length fits in int.
8993 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8995 * emacs.c (main): Do not reallocate argv, since there is a null at
8996 the end that can be overwritten, and this way there's no need to
8997 worry about size-calculation overflow.
8998 (sort_args): Check for size-calculation overflow.
9000 * eval.c (init_eval_once, grow_specpdl): Don't update size until
9002 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
9004 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
9005 (x_set_scroll_bar_width, x_figure_window_size):
9006 Check for integer overflow.
9007 (x_set_alpha): Do not assume XINT fits in int.
9009 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
9010 This is for the members text_lines, text_cols, total_lines, total_cols,
9011 where the system imposes an 'int' limit.
9013 * fringe.c (Fdefine_fringe_bitmap):
9014 Don't update size until alloc works.
9016 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
9017 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
9019 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
9020 Check for size-calculation overflow.
9021 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
9022 do, as we prefer signed integers.
9023 (id_to_widget.max_size, id_to_widget.used)
9024 (xg_store_widget_in_map, xg_remove_widget_from_map)
9025 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
9026 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
9027 Use and return ptrdiff_t, not int.
9028 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
9029 * gtkutil.h: Change prototypes to match the above.
9031 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
9032 are duplicate now that they've been promoted to lisp.h.
9033 (x_allocate_bitmap_record, x_alloc_image_color)
9034 (make_image_cache, cache_image, xpm_load):
9035 Don't update size until alloc is done.
9036 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
9038 Check for size calculation overflow.
9039 (ct_colors_allocated_max): New constant.
9040 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
9043 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
9044 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
9045 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
9046 Use ptrdiff_t, not int, to count maps.
9047 (read_char_minibuf_menu_prompt): Check for overflow in size
9048 calculations. Don't update size until allocation succeeds.
9049 Redo calculations to avoid overflow.
9050 * keyboard.h: Change prototypes to match the above.
9052 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
9054 (current_minor_maps): Check for size calculation overflow.

9076 (Fset_match_data): Don't assume list lengths fit in 'int'.
9078 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
9079 for command line length. Do not attempt to address one before the
9080 beginning of an array, as that's not portable.

9083 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
9085 (encode_terminal_code, calculate_costs): Check for size
9086 calculation overflow.
9087 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
9088 table lengths and related sizes. Don't update size until alloc
9089 done. Redo calculations to avoid overflow.

9108 Use ptrdiff_t, not int, for sizes.
9109 (Finternal_make_lisp_face, cache_face):
9110 Check for size calculation overflow.
9111 (cache_face): Treat size calculation overflows as if they were
9112 memory exhaustion (the usual treatment), rather than aborting.
9114 * xfns.c (x_encode_text, x_set_name_internal)
9115 (Fx_change_window_property): Use ptrdiff_t, not int, to count
9116 sizes, since they can exceed INT_MAX in size. Check for size
9117 calculation overflow.
9119 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
9120 (xg_select): Check for size calculation overflow.
9121 Don't update size until alloc done.
9123 * xrdb.c (get_environ_db): Don't assume path length fits in int,
9124 as sprintf is limited to int lengths.
9126 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
9127 (X_LONG_MIN): New macros.
9128 Use them to make the following changes clearer.
9129 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
9130 This change doesn't affect the value now, but it may help remind
9131 future maintainers not to raise the value too much later.
9132 (SELECTION_QUANTUM): Remove, replacing with ...
9133 (selection_quantum): ... new function, which avoids overflow.
9135 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
9136 assumption that selection length fits in 'int'.
9137 (x_reply_selection_request, x_handle_selection_request)
9138 (x_get_window_property, receive_incremental_selection)

9144 Redo calculations to avoid overflow.
9145 (x_reply_selection_request): When sending hint, ceiling it at
9146 X_LONG_MAX rather than relying on wraparound overflow to send

9149 (lisp_data_to_selection_data, x_property_data_to_lisp):
9150 Check for size-calculation overflow.

9153 Don't store size until memory allocation succeeds.
9154 (x_get_window_property): Plug memory leak on memory exhaustion.
9155 Don't double-block input; malloc is safe here. Don't assume 2**34
9156 - 4 fits in unsigned long. Add an xassert to check
9157 XGetWindowProperty overflow. Be more careful about overflow
9158 calculations, and distinguish size from memory overflow better.
9159 (receive_incremental_selection): When tracing, don't assume
9160 unsigned int is less than INT_MAX.
9161 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
9162 harmful) conversions of unsigned short to int.
9163 (lisp_data_to_selection_data): Don't assume that integers
9164 in the range -65535 through -1 fit in an X unsigned short.
9165 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
9166 result parameters unless successful. Rely on cons_to_unsigned
9167 to report problems with elements; the old code wasn't right anyway.
9168 (x_check_property_data): Check for int overflow; we cannot use
9169 a wider type due to X limits.
9170 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
9172 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

9202 * lisp.h (hash_lookup, hash_put):
9203 * minibuf.c (Ftest_completion):
9204 Use ptrdiff_t for hash table indexes, not int (which is too
9205 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
9206 32-bit --with-wide-int hosts).
9208 * charset.c (Fdefine_charset_internal): Check for integer overflow.
9209 Add a FIXME comment about memory leaks.

9238 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
9239 (x_send_scroll_bar_event): Likewise. Check that the size does not
9240 exceed limits imposed by XClientMessageEvent, as well as the usual
9241 ptrdiff_t and size_t limits.
9243 * keyboard.c: Overflow, signedness and related fixes.
9244 (make_lispy_movement): Use same integer type in forward decl
9245 that is used in the definition.
9246 (read_key_sequence, keyremap_step):
9247 Change bufsize argument back to int, undoing my 2011-03-30 change.
9248 We prefer signed types, and int is wide enough here.
9249 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
9250 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
9251 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
9252 length, not size_t. Use ptrdiff_t for index, not int.
9253 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
9254 possibility of integer overflow.

9277 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
9278 (lookup_image): Remove unnecessary tests.

9280 since parse_image_check makes sure they fit into int.
9281 (png_load, gif_load, svg_load_image):
9282 Prefer int to unsigned where either will do.
9283 (tiff_handler): New function, combining the cores of the
9284 old tiff_error_handler and tiff_warning_handler.
9285 This function is rewritten to use vsnprintf and thereby avoid
9286 stack buffer overflows. It uses only the features of vsnprintf
9287 that are common to both POSIX and native Microsoft.
9288 (tiff_error_handler, tiff_warning_handler): Use it.
9289 (tiff_load, gif_load, imagemagick_load_image):
9290 Don't assume :index value fits in 'int'.
9291 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
9292 (imagemagick_load_image): Check that crop parameters fit into
9293 the integer types that MagickCropImage accepts. Don't assume
9294 Vimagemagick_render_type has a nonnegative value. Don't assume
9295 size_t fits in 'long'.
9296 (gs_load): Use printmax_t to print the widest integers possible.

9309 handle_single_display_spec, not just 1 or zero.
9310 (handle_single_display_spec): If the display spec is of the form
9311 `(space ...)', and specifies display in the text area, return 2
9313 (try_cursor_movement): Check for the need to scroll more
9314 accurately, and prefer exact match for point under bidi.
9315 Don't advance `row' beyond the last row of the window.
9317 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
9318 into disp_prop; all users changed.
9320 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

9336 positioning on the newline at EOL of R2L text within L2R
9337 paragraph, and vice versa.
9338 (try_cursor_movement): Check continued rows, in addition to
9339 continuation rows. Fixes unwarranted scroll when point enters a
9340 continued line of R2L text within an L2R paragraph, or vice versa.
9341 (cursor_row_p): Consider the case of point being equal to
9342 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
9343 from the end of a short line to the beginning of a continued line
9344 of R2L text within L2R paragraph.

9371 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
9372 instead of CHAR_TO_BYTE. Fixes a crash when a completion
9373 candidate is selected by the mouse, and that candidate has a
9374 composed character under the mouse.
9376 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
9377 coordinates reported by pos-visible-in-window-p for a composed

9392 * image.c (gif_load): Don't assume that each subimage has the same
9393 dimensions as the base image. Handle disposal method that is
9394 "undefined" by the gif spec (Bug#9335).
9396 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
9398 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

9403 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
9404 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
9405 from an Org mode buffer to a Speedbar frame.
9407 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
9408 a composition, take its buffer position from IT->cmp_it.charpos.
9409 Fixes cursor positioning at the beginning of a line that begins
9410 with a composed character.
9412 2011-08-18 Eli Zaretskii <eliz@gnu.org>
9414 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
9415 character bidirectional type, use STRONG_L instead. Fixes crashes
9416 in a buffer produced by `describe-categories'.
9418 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
9419 members before the level stack, so they would be saved and
9420 restored when copying iterator state. Fixes incorrect reordering
9421 around TABs covered by display properties.
9423 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

9509 the event loop. Get status from as_status (Bug#7276).
9511 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9512 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit

9519 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
9520 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
9521 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
9522 (QCgnutls_bootprop_verify_hostname_error)
9523 (QCgnutls_bootprop_callbacks_verify): Rename from
9524 Qgnutls_bootprop_..., all uses changed.
9526 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
9529 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
9531 * xfaces.c (Qframe_set_background_mode): Now static.
9532 * dispextern.h (Qframe_set_background_mode): Remove decl.
9534 * process.c (Fnetwork_interface_info): Declare local only if needed.
9536 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
9538 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9539 (Fnetwork_interface_list): Allocate in increments of bytes instead
9540 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9541 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9543 (struct ifflag_def): notrailers is smart on OSX.
9544 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9545 Get hardware address with getifaddrs if available.
9547 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9549 * xdisp.c (iterate_out_of_display_property): xassert that
9550 IT->position is set to within IT->object's boundaries. Break from
9551 the loop as soon as EOB is reached; avoids infloops in redisplay
9552 when IT->position is set up wrongly due to some bug.
9553 Set IT->current to match the bidi iterator unconditionally.
9554 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9555 entry. Force push_it to save on the stack the current
9556 buffer/string position, to be restored by pop_it. Fix flags in
9557 the iterator structure wrt the object coming from a display
9558 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9559 properties. (Bug#9284)
9561 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9563 * fontset.c (fontset_get_font_group): Add proper type checks.
9566 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9568 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
9569 and LC_VERSION_MIN_MACOSX.
9570 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9571 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9573 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9575 * xdisp.c (forward_to_next_line_start): Allow to use the
9576 no-display-properties-and-no-overlays under bidi display.
9577 Set disp_pos in the bidi iterator to avoid searches for display
9578 properties and overlays.
9580 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9582 * editfns.c (Fset_time_zone_rule): Document relationship with the
9585 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9586 the font entity extracted from the cache (Bug#8109).
9588 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9590 * composite.c (autocmp_chars): Don't reset point. That is done by
9591 restore_point_unwind (Bug#5984).
9593 2011-08-07 Juri Linkov <juri@jurta.org>
9595 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9596 to show the arg `TIME' instead of `TIMEVAL'.
9598 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9600 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9601 display property strides EOL and includes a newline, as in
9602 longlines-mode. (Bug#9254)
9603 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9604 word-wrap under bidirectional display. (Bug#9224)
9606 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9607 is non-zero, even if the data buffer is NULL. Fixes a crash in
9608 vertical-motion with longlines-mode. (Bug#9254)
9610 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9612 * bidi.c <bidi_cache_total_alloc>: Now static.
9613 (bidi_initialize): Initialize bidi_cache_total_alloc.
9615 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9618 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9619 amount allocated this far in `bidi_cache_total_alloc'.
9620 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9621 non-zero, only free the data buffer without restoring the cache
9622 contents. All callers changed.
9624 * dispextern.h (bidi_unshelve_cache): Update prototype.
9626 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9627 (move_it_in_display_line, move_it_to)
9628 (move_it_vertically_backward, move_it_by_lines): Replace the call
9629 to xfree to an equivalent call to bidi_unshelve_cache.
9630 (move_it_in_display_line_to): Fix logic of returning
9631 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9633 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9635 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9636 came from a string character with a `cursor' property. (Bug#9229)
9638 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9640 * Makefile.in (LIB_PTHREAD): New variable.
9641 (LIBES): Add LIB_PTHREAD (Bug#9216).
9643 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9644 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9646 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9648 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9650 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9652 * xterm.c (x_find_topmost_parent): New function.
9653 (x_set_frame_alpha): Find topmost parent window with
9654 x_find_topmost_parent and set the property there also (bug#9181).
9655 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9657 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9659 * callproc.c (Fcall_process): Avoid vfork clobbering
9660 the local vars buffer, coding_systems, current_dir.
9662 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9664 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9666 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9668 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9669 so that it is not optimized away.
9671 * xdisp.c (compute_display_string_pos): Remove unused local.
9673 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9675 Fix slow cursor motion and scrolling in large buffers with
9676 selective display, like Org Mode buffers. (Bug#9218)
9678 * dispextern.h (struct bidi_it): New member disp_prop_p.
9680 * xdisp.c: Remove one-slot cache of display string positions.
9681 (compute_display_string_pos): Accept an additional argument
9682 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9683 for a display string or property. If found, set DISP_PROP_P
9686 * bidi.c (bidi_fetch_char): Accept an additional argument
9687 DISP_PROP_P, and pass it to compute_display_string_pos.
9688 Only handle text covered by a display string if DISP_PROP_P is returned
9689 non-zero. All callers of bidi_fetch_char changed.
9691 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9693 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9695 2010-12-03 Don March <don@ohspite.net>
9697 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9698 last character M-[char] is translated to ESC [char] (bug#7541).
9700 2011-08-02 Kenichi Handa <handa@m17n.org>
9702 * lisp.h (uniprop_table): Extern it.
9704 * chartab.c (uniprop_table): Make it non-static.
9706 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9708 * xdisp.c (forward_to_next_line_start): Accept additional argument
9709 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9711 (reseat_at_next_visible_line_start): Use the bidi iterator state
9712 returned by forward_to_next_line_start to restore the state of
9713 it->bidi_it after backing up to previous newline. (Bug#9212)
9715 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9717 * regex.c (re_comp): Protoize.
9718 (re_exec): Fix return type.
9719 (regexec): Fix type of `ret'. (Bug#9203)
9721 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9723 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9724 This is needed if max-image-size is a floating-point number.
9726 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9728 * print.c (print_object): Print empty symbol as ##.
9730 * lread.c (read1): Read ## as empty symbol.
9732 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9734 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9735 setting frame foreground color (Bug#9175).
9736 (x_set_background_color): Likewise.
9738 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9739 contents (Bug#9176).
9740 (EmacsTooltip -init): Remove bezels and add shadows to
9743 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9744 or scroll bar (Bug#8470).
9746 * nsfont.m (nsfont_open): Remove assignment to voffset and
9747 unnecessary vars hshink, expand, hd, full_height, min_height.
9748 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9750 * nsterm.h (nsfont_info): Remove voffset field.
9752 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9754 Implement strike-through and overline on NextStep (Bug#8863).
9756 * nsfont.m (nsfont_open): Use underline position provided by font,
9757 instead of hard-coded value of 2.
9758 (nsfont_draw): Call ns_draw_text_decoration instead.
9760 * nsterm.h: Add declaration for ns_draw_text_decoration.
9762 * nsterm.m (ns_draw_text_decoration): New function for drawing
9763 underline, overline, and strike-through.
9764 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9765 ns_draw_text_decoration. Change treatment of cursor drawing to
9766 accommodate underlining, etc.
9768 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9770 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9773 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9775 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9776 Without this fix, if a signal arrives just after memory fills up,
9777 'malloc' might be invoked reentrantly.
9779 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9780 In other words, assume that every image size is allowed, on non-X
9781 hosts. This assumption is probably wrong, but it lets Emacs compile.
9783 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9785 * regex.c (re_iswctype): Convert return values to boolean.
9787 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9789 * xdisp.c (compute_display_string_pos): Don't use cached display
9790 string position if the buffer had its restriction changed.
9793 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9795 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9797 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9799 Integer signedness and overflow and related fixes. (Bug#9079)
9801 * bidi.c: Integer size and overflow fixes.
9802 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9803 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9804 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9805 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9806 (bidi_find_other_level_edge):
9807 Use ptrdiff_t instead of EMACS_INT where either will do.
9808 This works better on 32-bit hosts configured --with-wide-int.
9809 (bidi_cache_ensure_space): Check for size-calculation overflow.
9810 Use % rather than repeated addition, for better worst-case speed.
9811 Don't set bidi_cache_size until after xrealloc returns, because it
9813 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9814 (bidi_cache_ensure_space): Also check that the bidi cache size
9815 does not exceed that of the largest Lisp string or buffer. See Eli
9816 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9818 * alloc.c (__malloc_size_t): Remove.
9819 All uses replaced by size_t. See Andreas Schwab's note
9820 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9822 * image.c: Improve checking for integer overflow.
9823 (check_image_size): Assume that f is nonnull, since
9824 it is always nonnull in practice. This is one less thing to
9825 worry about when checking for integer overflow later.
9826 (x_check_image_size): New function, which checks for integer
9827 overflow issues inside X.
9828 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9829 This removes the need for a memory_full check.
9830 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9831 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9832 (xbm_read_bitmap_data): Change locals back to 'int', since
9833 their values must fit in 'int'.
9834 (xpm_load_image, png_load, tiff_load):
9835 Invoke x_create_x_image_and_pixmap earlier,
9836 to avoid much needless work if the image is too large.
9837 (tiff_load): Treat overly large images as if
9838 x_create_x_image_and_pixmap failed, not as malloc failures.
9839 (gs_load): Use x_check_image_size.
9841 * gtkutil.c: Omit integer casts.
9842 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9843 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9845 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9847 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9848 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9849 would wrongly return t on a 64-bit host.
9851 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9852 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9853 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9854 and therefore cause GCC to emit a bogus diagnostic in some cases.
9856 * image.c: Integer signedness and overflow and related fixes.
9857 This is not an exhaustive set of fixes, but it's time to
9858 record what I've got.
9859 (lookup_pixel_color, check_image_size): Remove redundant decls.
9860 (check_image_size): Don't assume that arbitrary EMACS_INT values
9861 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9862 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9863 (tiff_load, imagemagick_load_image):
9864 Check for overflow in size calculations.
9865 (x_create_x_image_and_pixmap): Remove unnecessary test for
9866 xmalloc returning NULL; that can't happen.
9867 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9868 (xpm_color_bucket): Use better integer hashing function.
9869 (xpm_cache_color): Don't possibly over-allocate memory.
9870 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9871 (gif_memory_source):
9872 Use ptrdiff_t, not int or size_t, to record sizes.
9873 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9874 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9875 either works, as we prefer signed integers.
9876 (tiff_read_from_memory, tiff_write_from_memory):
9877 Return tsize_t, not size_t, since that's what the TIFF API wants.
9878 (tiff_read_from_memory): Don't fail simply because the read would
9879 go past EOF; instead, return a short read.
9880 (tiff_load): Omit no-longer-needed casts.
9881 (Fimagemagick_types): Don't assume size fits into 'int'.
9883 Improve hashing quality when configured --with-wide-int.
9884 * fns.c (hash_string): New function, taken from sxhash_string.
9885 Do not discard information about ASCII character case; this
9886 discarding is no longer needed.
9887 (sxhash-string): Use it. Change sig to match it. Caller changed.
9888 * lisp.h: Declare it.
9889 * lread.c (hash_string): Remove, since we now use fns.c's version.
9890 The fns.c version returns a wider integer if --with-wide-int is
9891 specified, so this should help the quality of the hashing a bit.
9893 * emacs.c: Integer overflow minor fix.
9894 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9895 Define only if GNU_LINUX.
9896 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9898 * dispnew.c: Integer signedness and overflow fixes.
9899 Remove unnecessary forward decls, that were a maintenance hassle.
9900 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9902 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9903 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9904 (prepare_desired_row, line_draw_cost):
9905 Use int, not unsigned, where either works.
9906 (save_current_matrix, restore_current_matrix):
9907 Use ptrdiff_t, not size_t, where either works.
9908 (init_display): Check for overflow more accurately, and without
9909 relying on undefined behavior.
9911 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9912 Remove, replacing with the new symbols in lisp.h. All uses changed.
9913 * fileio.c (make_temp_name):
9914 * filelock.c (lock_file_1, lock_file):
9915 * xdisp.c (message_dolog):
9916 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9917 Use pMd etc. instead.
9918 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9919 replacing the pWIDE etc. symbols removed from editfns.c.
9921 * keyboard.h (num_input_events): Now uintmax_t.
9922 This is (very slightly) less likely to mess up due to wraparound.
9925 * buffer.c: Integer signedness fixes.
9926 (alloc_buffer_text, enlarge_buffer_text):
9927 Use ptrdiff_t rather than size_t when either will do, as we prefer
9930 * alloc.c: Integer signedness and overflow fixes.
9931 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9932 (__malloc_size_t): Default to size_t, not to int.
9933 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9934 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9935 Prefer ptrdiff_t to size_t when either would do, as we prefer
9937 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9938 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9939 Now const. Initialize with values that are in range even if char
9941 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9942 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9943 These functions do the right thing with sizes > 2**32.
9944 (check_depth): Now ptrdiff_t, not int.
9945 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9946 Adjust to new way of storing sizes. Check for size overflow bugs
9948 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9949 slightly wrong anyway, as it missed one instance of
9950 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9951 (refill_memory_reserve): Omit needless cast to size_t.
9952 (mark_object_loop_halt): Mark as externally visible.
9954 * xselect.c: Integer signedness and overflow fixes.
9955 (Fx_register_dnd_atom, x_handle_dnd_message):
9956 Use ptrdiff_t, not size_t, since we prefer signed.
9957 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9958 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9959 x_dnd_atoms_size and x_dnd_atoms_length.
9961 * doprnt.c: Prefer signed to unsigned when either works.
9963 * doprnt.c (doprnt):
9965 * xdisp.c (vmessage):
9966 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9967 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9968 prefer signed arithmetic to avoid comparison confusion.
9969 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9970 but is a bit tricky.
9972 Assume freestanding C89 headers, string.h, stdlib.h.
9973 * data.c, doprnt.c, floatfns.c, print.c:
9974 Include float.h unconditionally.
9975 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9976 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9977 * regex.c: Likewise for stddef.h, string.h.
9978 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9979 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9980 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9981 (STDC_HEADERS): Remove obsolete defines.
9982 * sysdep.c: Include limits.h unconditionally.
9984 Assume support for memcmp, memcpy, memmove, memset.
9985 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9986 * regex.c (memcmp, memcpy):
9987 Remove; we assume C89 now.
9989 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9990 (__malloc_safe_bcopy): Remove; no longer needed.
9992 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9993 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9994 well either way, and we prefer signed to unsigned.
9996 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9998 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9999 closes the connection while we're reading (bug#9182).
10001 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
10003 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
10004 are specified (Bug#9168).
10006 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
10008 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
10009 Found by GCC static checking and --with-wide-int on a 32-bit host.
10011 2011-07-25 Eli Zaretskii <eliz@gnu.org>
10013 * xdisp.c (compute_display_string_pos): Fix logic of caching
10014 previous display string position. Initialize cached_prev_pos to
10015 -1. Fixes slow-down at the beginning of a buffer.
10017 2011-07-24 Eli Zaretskii <eliz@gnu.org>
10019 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
10020 for attrs[LFACE_FONTSET_INDEX].
10022 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
10024 * xml.c (parse_region): Remove unused local
10025 that was recently introduced.
10027 2011-07-23 Eli Zaretskii <eliz@gnu.org>
10029 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
10030 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
10032 * xdisp.c (move_it_in_display_line_to): Record the best matching
10033 position for TO_CHARPOS while scanning the line, and restore it on
10034 exit if none of the characters scanned was an exact match.
10035 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
10036 when exact match is impossible due to invisible text, and the
10037 lines are truncated.
10039 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
10041 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
10044 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10046 Fix a significant slow-down of cursor motion with C-n, C-p,
10047 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
10048 auto-repeat under bidi redisplay in fontified buffers.
10049 * xdisp.c (compute_stop_pos_backwards): New function.
10050 (next_element_from_buffer): Call compute_stop_pos_backwards to
10051 find a suitable prev_stop when we find ourselves before
10053 (reseat): Don't look for prev_stop, as that could mean a very long
10055 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
10056 <cached_disp_overlay_modiff>: Cache for last found display string
10058 (compute_display_string_pos): Return the cached position if asked
10059 about the same buffer in the same area of character positions, and
10060 the buffer wasn't changed since the time the display string
10061 position was cached.
10063 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10065 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
10066 is an integer, which is important for empty lines. (Bug#9149)
10068 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
10070 * frame.c (Fmodify_frame_parameters): In tty case, update the
10071 default face if necessary (Bug#4238).
10073 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
10075 * editfns.c (Fstring_to_char): No need to explain what a character
10076 is in the docstring (Bug#6576).
10078 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10080 * xml.c (parse_region): Make sure we always return a tree.
10082 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
10084 * xml.c (parse_region): If a document contains only comments,
10087 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10089 * xml.c (make_dom): Return comments, too.
10091 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
10094 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
10095 and the surrounding thread.
10096 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
10097 rather than fgets, and retry after EINTR. Otherwise, 'emacs
10098 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
10100 * s/openbsd.h (BROKEN_SIGIO): Define.
10101 * unexelf.c (unexec) [__OpenBSD__]:
10102 Don't update the .mdebug section of the Alpha COFF symbol table.
10104 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10106 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
10109 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
10111 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
10112 This fixes some race conditions on the permissions of any newly
10115 * alloc.c (valid_pointer_p): Use pipe, not open.
10116 This fixes some permissions issues when debugging.
10118 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
10119 If fchown fails to set both uid and gid, try to set just gid,
10120 as that is sometimes allowed. Adjust the file's mode to eliminate
10121 setuid or setgid bits that are inappropriate if fchown fails.
10123 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
10125 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
10126 to compare Lisp_Objects.

10131 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
10133 * lread.c (read_integer): Unread even EOF character.
10134 (read1): Likewise. Properly record start position of symbol.
10136 * lread.c (read1): Read `#:' as empty uninterned symbol if no
10137 symbol character follows.
10139 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
10141 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
10142 This works around a problem with the previous change to Fcopy_file.
10143 Recent glibc declares fchown with __attribute__((warn_unused_result)),
10144 and without this change, GCC might complain about discarding
10145 fchown's return value.
10147 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
10149 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
10151 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
10153 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
10155 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
10157 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
10158 it's used from the C level.
10160 * process.c: Use the same condition for POLL_FOR_INPUT in both
10161 keyboard.c and process.c (bug#1858).
10163 2011-07-09 Lawrence Mitchell <wence@gmx.li>
10165 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
10166 (Fgnutls_boot): Use it.
10168 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
10170 * doc.c (Fsubstitute_command_keys): Revert last change.
10172 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
10174 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
10175 quotes the next character, and doesn't affect other longer
10176 sequences (bug#8935).
10178 * lread.c (syms_of_lread): Clarify that is isn't only
10179 `eval-buffer' and `eval-defun' that's affected by
10180 `lexical-binding' (bug#8460).
10182 2011-07-15 Eli Zaretskii <eliz@gnu.org>
10184 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
10185 bidi redisplay when a line includes both an image and is truncated.
10187 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
10189 Fix minor problems found by static checking.
10190 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
10191 (elsz): Now a signed constant, not a size_t var. We prefer signed
10192 types to unsigned, to avoid integer comparison confusion. Without
10193 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
10194 "cannot optimize loop, the loop counter may overflow", a symptom
10196 * indent.c (Fvertical_motion): Mark locals as initialized.
10197 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
10199 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
10201 * search.c (Fre_search_backward): Mention `case-fold-search' in
10202 all the re_search_* functions (bug#8138).

10222 buffer position was specified. Initialize paragraph_embedding to
10224 (reseat_to_string): Initialize the bidi iterator.
10225 (display_string): If we need to ignore text properties of
10226 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
10227 original value of -1 will not work with bidi.)
10228 (compute_display_string_pos): First arg is now struct
10229 `text_pos *'; all callers changed. Support display properties on
10231 (compute_display_string_end): Support display properties on Lisp
10233 (init_iterator, reseat_1, reseat_to_string): Initialize the
10234 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
10235 when iterating on a string not from display properties).
10236 (compute_display_string_pos, compute_display_string_end):
10237 Fix calculation of the object to scan. Fixes an error when using
10239 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
10240 base_level_stop; instead, set base_level_stop to BEGV.
10241 Fixes crashes in vertical-motion.
10242 (next_element_from_buffer): Improve commentary for when
10243 the iterator is before prev_stop.
10244 (init_iterator): Initialize bidi_p from the default value of
10245 bidi-display-reordering, not from buffer-local value. Use the
10246 buffer-local value only if initializing for buffer iteration.
10247 (handle_invisible_prop): Support invisible properties on strings
10248 that are being bidi-reordered.
10249 (set_iterator_to_next): Support bidi reordering of C strings and
10251 (next_element_from_string): Support bidi reordering of Lisp

10255 Use IT_STRING_CHARPOS when displaying from a Lisp string.
10256 (init_iterator): Don't initialize it->bidi_p for strings
10258 (reseat_to_string): Initialize it->bidi_p for strings here.

10265 character that is not the first one in the visual order.
10266 (get_visually_first_element): New function, refactored from common
10267 parts of next_element_from_buffer, next_element_from_string, and
10268 next_element_from_c_string.
10269 (tool_bar_lines_needed, redisplay_tool_bar)
10270 (display_menu_bar): Force left-to-right direction. Add a FIXME
10271 comment for making that be controlled by a user option.
10272 (push_it, pop_it): Save and restore the state of the
10273 bidi iterator. Save and restore the bidi_p flag.
10274 (pop_it): Iterate out of display property for string iteration as

10277 (handle_single_display_spec): Set up it->bidi_it for iteration
10278 over a display string, and call bidi_init_it.

10280 (get_overlay_strings_1, push_display_prop): Set up the bidi
10281 iterator for displaying display or overlay strings.
10282 (forward_to_next_line_start): Don't use the shortcut if
10284 (back_to_previous_visible_line_start): If handle_display_prop
10285 pushed the iterator stack, restore the internal state of the bidi
10286 iterator by calling bidi_pop_it same number of times.
10287 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
10288 and we are bidi-iterating, don't decrement the iterator position;
10289 instead, set the first_elt flag in the bidi iterator, to produce
10291 (reseat_1): Remove redundant setting of string_from_display_prop_p.
10292 (push_display_prop): xassert that we are iterating a buffer.
10293 (push_it, pop_it): Save and restore paragraph_embedding member.
10294 (handle_single_display_spec, next_overlay_string)
10295 (get_overlay_strings_1, reseat_1, reseat_to_string)
10296 (push_display_prop): Set up the `unibyte' member of bidi_it.string
10297 correctly. Don't assume unibyte strings are not bidi-reordered.
10298 (compute_display_string_pos)
10299 (compute_display_string_end): Fix handling the case of C string.
10300 (push_it, pop_it): Save and restore from_disp_prop_p.

10306 property. Fix a typo in popping stretch info. Add an assertion
10307 for verifying that the iterator position is in sync with the bidi
10309 (handle_single_display_spec, get_overlay_strings_1)

10327 (move_it_in_display_line_to): If iterator ended up at
10328 EOL, but we never saw any buffer positions smaller than
10329 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
10330 motion in bidi-reordered lines.

10332 immediately before the call to set_iterator_to_next. Fixes cursor
10333 motion in bidi-reordered lines with stretch glyphs and strings
10334 displayed in margins. (Bug#8133) (Bug#8867)
10335 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
10337 (pos_visible_p): Support positions in bidi-reordered lines.
10338 Save and restore bidi cache.
10340 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
10341 (bidi_paragraph_info): Delete unused struct.

10359 Support iteration over a string.
10360 (bidi_set_sor_type, bidi_resolve_explicit_1)
10361 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
10362 can now be zero (for strings); special values 0 and -1 were
10363 changed to -1 and -2, respectively.
10364 (bidi_char_at_pos): New function.
10365 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

10451 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
10453 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
10454 The old code sometimes used this field without initializing it.
10456 * alloc.c (gc_sweep): Don't read past end of array.
10457 In theory, the old code could also have corrupted Emacs internals,
10458 though it'd be very unlikely.

10723 This isn't true in general, and it's particularly not true
10724 if Emacs is configured with --with-wide-int.
10725 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

10762 Random fixes. E.g., (random) never returned negative values.
10763 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10764 subseconds part to the entropy, as that's a bit more random.
10765 Prefer signed to unsigned, since the signedness doesn't matter and
10766 in general we prefer signed. When given a limit, use a
10767 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10768 latter isn't right if USE_2_TAGS_FOR_INTS.
10769 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10770 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10782 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
10783 This is more efficient than Ffile_directory_p and avoids a minor race.
10785 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
10787 * buffer.c (Foverlay_put): Say what the return value is
10790 * fileio.c (barf_or_query_if_file_exists): Check first if the file
10791 is a directory before asking whether to use the file name

10794 error be more correct.
10796 * fns.c (Frequire): Remove the mention of the .gz files, since
10797 that's installation-specific, but keep the mention of

10810 Qgnutls_bootprop_verify_error (which is no longer used).
10812 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
10813 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10814 Also (re)move comments that are misplaced or no longer relevant.

10843 * lread.c (syms_of_lread): Mention single symbols defined by
10844 `defvar' or `defconst' (bug#7154).
10846 * fns.c (Frequire): Mention .el.gz files (bug#7314).
10847 (Frequire): Mention get-load-suffixes.

10915 * eval.c (struct backtrace): Simplify and port the data structure.
10916 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10917 signed bit field, as this assumption is not portable and it makes
10918 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10919 "char debug_on_exit : 1" as this is not portable either; instead,
10920 use the portable "unsigned int debug_on_exit : 1". Remove unused
10921 member evalargs. Remove obsolete comments about cc bombing out.
10923 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

10993 (emacs_fixed_get_preferred_height): Use min_width/height from
10994 frames size_hint to set minimum and natural (Bug#8919).
10995 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10996 and use min_width/height from frames size_hint to set
10997 min_width/height (Bug#8919).

11089 * print.c (printchar, strout): Check for string overflow.
11090 (PRINTPREPARE, printchar, strout):
11091 Don't set size unless allocation succeeds.
11093 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
11094 for sizes. Check for string overflow more accurately.

11098 * keyboard.h (struct keyboard.kbd_macro_bufsize):
11099 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

11105 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
11107 * lread.c: Integer overflow fixes.
11108 (read_integer): Radix is now EMACS_INT, not int,
11109 to improve quality of diagnostics for out-of-range radices.
11110 Calculate buffer size correctly for out-of-range radices.
11111 (read1): Check for integer overflow in radices, and in
11112 read-circle numbers.
11113 (read_escape): Avoid int overflow.
11114 (Fload, openp, read_buffer_size, read1)
11115 (substitute_object_recurse, read_vector, read_list, map_obarray):
11116 Use ptrdiff_t, not int, for sizes.

11131 2011-06-22 Leo Liu <sdl.web@gmail.com>
11133 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
11134 Move to minibuffer.el.
11136 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
11138 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
11139 The following patches are for when GLYPH_DEBUG && !XASSERT.
11140 * dispextern.h (trace_redisplay_p, dump_glyph_string):
11141 * dispnew.c (flush_stdout):
11142 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
11143 Mark as externally visible.
11144 * dispnew.c (check_window_matrix_pointers): Now static.
11145 * dispnew.c (window_to_frame_vpos):
11146 * xfns.c (unwind_create_frame):

11153 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
11155 (debug_method_add): Use va_list and vsprintf rather than relying
11156 on undefined behavior with wrong number of arguments.
11157 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
11158 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
11159 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
11160 since we're not interested in debugging glyphs with old libraries.
11161 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
11162 GCC 4.6.0's static checking.
11164 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
11166 Integer overflow and signedness fixes (Bug#8873).

11178 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
11180 * xfaces.c (load_pixmap):
11181 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
11182 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
11183 (.bitmaps_last, struct x_output.icon_bitmap):
11184 Use ptrdiff_t, not int, for bitmap indexes.
11185 (x_allocate_bitmap_record): Check for size overflow.
11186 * dispextern.h, lisp.h: Adjust to API changes elsewhere.

11198 Use ptrdiff_t, not int, for sizes.
11199 (overlays_at, overlays_in): Check for size-calculation overflow.
11201 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
11203 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
11204 (x_session_initialize): Do not assume string length fits in int.
11206 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
11207 This is unlikely, but can occur if DPI is outlandish.
11209 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
11210 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
11212 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
11213 * xrdb.c (magic_file_p, search_magic_path):
11214 Omit last arg SUFFIX; it was always 0. All callers changed.
11215 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
11217 * xfont.c (xfont_match): Avoid need for strlen.
11219 * xfns.c: Don't assume strlen fits in int.

11222 * xdisp.c (message_log_check_duplicate): Return intmax_t,
11223 not unsigned long, as we prefer signed integers. All callers changed.
11224 Detect integer overflow in repeat count.
11225 (message_dolog): Don't assume print length fits in 39 bytes.
11226 (display_mode_element): Don't assume strlen fits in int.
11228 * termcap.c: Don't assume sizes fit in int and never overflow.
11229 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.

11232 * minibuf.c (Fread_buffer):
11233 * lread.c (intern, intern_c_string):
11234 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

11247 * filelock.c: Fix some buffer overrun and integer overflow issues.
11248 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
11249 Reformulate so as not to need the command string.
11250 Invoke gzip -cd rather than gunzip, as it's more portable.
11251 (lock_info_type, lock_file_1, lock_file):
11252 Don't assume pid_t and time_t fit in unsigned long.
11253 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
11254 (current_lock_owner): Prefer signed type for sizes.
11255 Use memcpy, not strncpy, where memcpy is what is really wanted.
11256 Don't assume (via atoi) that time_t and pid_t fit in int.
11257 Check for time_t and/or pid_t out of range, e.g., via a network share.
11258 Don't alloca where an auto var works fine.
11260 * fileio.c: Fix some integer overflow issues.
11261 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
11262 Don't assume string length fits in int.
11263 (directory_file_name): Don't assume string length fits in long.
11264 (make_temp_name): Don't assume pid fits in int, or that its print
11265 length is less than 20.

11284 (Fgetenv_internal):
11285 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
11287 * lread.c (invalid_syntax): Omit length argument.
11288 All uses changed. This doesn't fix a bug, but it simplifies the
11289 code away from its former Hollerith-constant appearance, and it's
11290 one less 'int' to worry about when looking at integer-overflow issues.
11291 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
11293 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
11294 This didn't break anything, but it didn't help either.
11295 It's confusing to put a bogus integer in a place where the actual
11296 value does not matter.
11297 (LIST_END_P): Remove unused macro and its bogus comment.
11298 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
11300 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
11301 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
11303 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
11304 We prefer signed types, and the value cannot exceed the EMACS_INT
11305 range anyway (because otherwise the length would not be representable).
11306 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
11307 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
11308 This avoids a GCC warning when WIDE_EMACS_INT.
11310 * indent.c (sane_tab_width): New function.
11311 (current_column, scan_for_column, Findent_to, position_indentation)
11312 (compute_motion): Use it. This is just for clarity.
11313 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
11315 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
11317 * lisp.h (lint_assume): New macro.
11318 * composite.c (composition_gstring_put_cache):
11319 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
11321 * editfns.c, insdel.c:
11322 Omit unnecessary forward decls, to simplify future changes.
11324 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
11326 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
11328 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
11329 Use much-faster test for byte-length change.
11330 Don't assume string byte-length fits in 'int'.
11331 Check that character arg fits in 'int'.
11332 (mapcar1): Declare byte as byte, for clarity.
11334 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
11336 * fns.c (concat): Catch string overflow earlier.
11337 Do not rely on integer wraparound.
11339 * dispextern.h (struct it.overlay_strings_charpos)
11340 (struct it.selective): Now EMACS_INT, not int.
11341 * xdisp.c (forward_to_next_line_start)
11342 (back_to_previous_visible_line_start)
11343 (reseat_at_next_visible_line_start, next_element_from_buffer):
11344 Don't arbitrarily truncate the value of 'selective' to int.
11346 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
11348 * composite.c: Don't truncate sizes to 'int'.
11349 (composition_gstring_p, composition_reseat_it)
11350 (composition_adjust_point): Use EMACS_INT, not int.
11351 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
11352 not EMACS_UINT, for indexes.
11354 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
11356 * buffer.c: Include <verify.h>.
11357 (struct sortvec.priority, struct sortstr.priority):
11358 Now EMACS_INT, not int.
11359 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
11360 (struct sortstr.size, record_overlay_string)
11361 (struct sortstrlist.size, struct sortlist.used):
11362 Don't truncate size to int.
11363 (record_overlay_string): Check for size-calculation overflow.
11364 (init_buffer_once): Check at compile-time, not run-time.
11366 2011-06-22 Jim Meyering <meyering@redhat.com>
11368 Don't leak an XBM-image-sized buffer
11369 * image.c (xbm_load): Free the image buffer after using it.
11371 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
11374 * composite.c (find_automatic_composition): Omit needless 'return 0;'
11375 that Sun C diagnosed.
11376 * fns.c (secure_hash): Fix pointer signedness issue.
11377 * intervals.c (static_offset_intervals): New function.
11378 (offset_intervals): Use it.
11380 2011-06-21 Leo Liu <sdl.web@gmail.com>
11383 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
11386 * fns.c (secure_hash): Rename from crypto_hash_function and change
11387 the first arg to accept symbols.
11388 (Fsecure_hash): New primitive.
11389 (syms_of_fns): New symbols.
11391 2011-06-20 Deniz Dogan <deniz@dogan.se>
11393 * process.c (Fset_process_buffer): Clarify return value in
11396 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
11398 * dispnew.c (add_window_display_history): Use BVAR.
11400 * xdisp.c (debug_method_add): Use BVAR.
11401 (check_window_end, dump_glyph_matrix, dump_glyph)
11402 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
11404 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
11407 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
11408 check till after the cache is created in init_frame_faces.
11410 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
11412 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
11414 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
11416 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
11417 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
11418 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
11420 Improve buffer-overflow checking (Bug#8873).
11421 * fileio.c (Finsert_file_contents):
11422 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
11423 Remove the old (too-loose) buffer overflow checks.
11424 They weren't needed, since make_gap checks for buffer overflow.
11425 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
11426 The old code merely checked for Emacs fixnum overflow, and relied
11427 on undefined (wraparound) behavior. The new code avoids undefined
11428 behavior, and also checks for ptrdiff_t and/or size_t overflow.
11430 * editfns.c (Finsert_char): Don't dump core with very negative counts.
11431 Tune. Don't use wider integers than needed. Don't use alloca.
11432 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
11434 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
11436 * insdel.c, lisp.h (buffer_overflow): New function.
11437 (insert_from_buffer_1, replace_range, replace_range_2):
11438 * insdel.c (make_gap_larger):
11439 * editfns.c (Finsert_char):
11440 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11442 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11444 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11446 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11448 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11449 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11451 * fileio.c: Don't assume EMACS_INT fits in off_t.
11452 (emacs_lseek): New static function.
11453 (Finsert_file_contents, Fwrite_region): Use it.
11454 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11456 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11458 * fns.c: Don't overflow int when computing a list length.
11459 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11460 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11461 truncation on 64-bit hosts. Check for QUIT every
11462 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
11463 faster and is responsive enough.
11464 (Flength): Report an error instead of overflowing an integer.
11465 (Fsafe_length): Return a float if the value is not representable
11466 as a fixnum. This shouldn't happen except in contrived situations.
11467 (Fnthcdr, Fsort): Don't assume list length fits in int.
11468 (Fcopy_sequence): Don't assume vector length fits in int.
11470 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11471 (header_size, word_size): New constants.
11472 (allocate_vectorlike): Don't check size overflow here.
11473 (allocate_vector): Check it here instead, since this is the only
11474 caller of allocate_vectorlike that could cause overflow.
11475 Check that the new vector's length is representable as a fixnum.
11477 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11478 The previous code was bogus. For example, next_almost_prime (32)
11479 returned 39, which is undesirable as it is a multiple of 3; and
11480 next_almost_prime (24) returned 25, which is a multiple of 5 so
11481 why was the code bothering to check for multiples of 7?
11483 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11485 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11487 Variadic C functions now count arguments with ptrdiff_t.
11488 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11489 Back then I didn't know that the Emacs coding style prefers signed int.
11490 Also, in the meantime I found a few more instances where arguments
11491 were being counted with int, which may truncate counts on 64-bit
11492 machines, or EMACS_INT, which may be unnecessarily wide.
11493 * lisp.h (struct Lisp_Subr.function.aMANY)
11494 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11495 Arg counts are now ptrdiff_t, not size_t.
11496 All variadic functions and their callers changed accordingly.
11497 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11498 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11499 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11500 * callint.c (Fcall_interactively): Check arg count for overflow,
11501 to avoid potential buffer overrun. Use signed char, not 'int',
11502 for 'varies' array, so that we needn't bother to check its size
11503 calculation for overflow.
11504 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11505 * eval.c (apply_lambda):
11506 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11507 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11508 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11510 * callint.c (Fcall_interactively): Don't use index var as event count.
11512 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11513 * mem-limits.h (SIZE): Remove; no longer used.
11515 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11517 Remove unnecessary casts.
11518 * xterm.c (x_term_init):
11519 * xfns.c (x_set_border_pixel):
11520 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11521 These aren't needed now that we assume ANSI C.
11523 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11524 It's more likely to cause problems (due to unsigned overflow)
11527 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11529 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11531 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11533 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11535 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11537 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11539 GLYPH_CODE_FACE returns EMACS_INT, not int.
11540 * dispextern.h (merge_faces):
11541 * xfaces.c (merge_faces):
11542 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11543 Don't assume EMACS_INT fits in int.
11545 * character.h (CHAR_VALID_P): Remove unused parameter.
11546 * fontset.c, lisp.h, xdisp.c: All uses changed.
11548 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11550 * fns.c (concat): Minor tuning based on overflow analysis.
11551 This doesn't fix any bugs. Use int to hold character, instead
11552 of constantly refetching from Emacs object. Use XFASTINT, not
11553 XINT, for value known to be a character. Don't bother comparing
11554 a single byte to 0400, as it's always less.
11556 * floatfns.c (Fexpt):
11557 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11559 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11562 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11564 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11565 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11566 incorrectly succeed when S was a string, because 4294967386 was
11567 truncated before it was used.
11569 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11570 Otherwise, an out-of-range integer could cause undefined behavior
11573 * composite.c: Use int, not EMACS_INT, for characters.
11574 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11575 EMACS_INT, for values that are known to be in character range.
11576 This doesn't fix any bugs but is the usual style inside Emacs and
11577 may generate better code on 32-bit machines.
11579 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11580 This is for reasons similar to the recent CHAR_STRING fix.
11581 * charset.c (Fencode_char): Check that character arg is actually
11582 a character. Pass an int to ENCODE_CHAR.
11583 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11584 wider than 'int', as a compile-time check to prevent future regressions
11587 * character.c (char_string): Remove unnecessary casts.
11589 Make sure a 64-bit char is never passed to CHAR_STRING.
11590 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11591 by silently ignoring the top 32 bits, allowing some values
11592 that were far too large to be valid characters.
11593 * character.h: Include <verify.h>.
11594 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11595 arguments are no wider than unsigned, as a compile-time check
11596 to prevent future regressions in this area.
11598 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11599 (Fsubst_char_in_region):
11601 * xdisp.c (decode_mode_spec_coding):
11602 Adjust to CHAR_STRING's new requirement.
11603 * editfns.c (Finsert_char, Fsubst_char_in_region):
11604 * fns.c (concat): Check that character args are actually
11605 characters. Without this test, these functions did the wrong
11606 thing with wildly out-of-range values on 64-bit hosts.
11608 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11609 These casts should not be needed on 32-bit hosts, either.
11610 * keyboard.c (read_char):
11611 * lread.c (Fload): Remove casts to unsigned.
11613 * lisp.h (UNSIGNED_CMP): New macro.
11614 This fixes comparison bugs on 64-bit hosts.
11615 (ASCII_CHAR_P): Use it.
11616 * casefiddle.c (casify_object):
11617 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11618 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11619 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11620 * dispextern.h (FACE_FROM_ID):
11621 * keyboard.c (read_char): Use UNSIGNED_CMP.
11623 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11624 not to EMACS_INT, to avoid GCC warning.
11626 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11628 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11629 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11630 isn't needed on 32-bit machines.
11632 * buffer.c (Fgenerate_new_buffer_name):
11633 Use EMACS_INT for count, not int.
11634 (advance_to_char_boundary): Return EMACS_INT, not int.
11636 * data.c (Qcompiled_function): Now static.
11638 * window.c (window_body_lines): Now static.
11640 * image.c (gif_load): Rename local to avoid shadowing.
11642 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11643 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11644 * alloc.c (make_save_value): Integer argument is now of type
11645 ptrdiff_t, not int.
11646 (mark_object): Use ptrdiff_t, not int.
11647 * lisp.h (pD): New macro.
11648 * print.c (print_object): Use it.
11650 * alloc.c: Use EMACS_INT, not int, to count objects.
11651 (total_conses, total_markers, total_symbols, total_vector_size)
11652 (total_free_conses, total_free_markers, total_free_symbols)
11653 (total_free_floats, total_floats, total_free_intervals)
11654 (total_intervals, total_strings, total_free_strings):
11655 Now EMACS_INT, not int. All uses changed.
11656 (Fgarbage_collect): Compute overall total using a double, so that
11657 integer overflow is less likely to be a problem. Check for overflow
11658 when converting back to an integer.
11659 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11660 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11661 These were 'int' variables that could overflow on 64-bit hosts;
11662 they were never used, so remove them instead of repairing them.
11663 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11664 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11665 Previously, this ceilinged at INT_MAX, but that doesn't work on
11667 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11669 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11670 (allocate_vectorlike): Check for ptrdiff_t overflow.
11671 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11672 when a (possibly-narrower) signed value would do just as well.
11673 We prefer using signed arithmetic, to avoid comparison confusion.
11675 * alloc.c: Catch some string size overflows that we were missing.
11676 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11677 for convenience in STRING_BYTES_MAX.
11678 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11679 The definition here is exact; the one in lisp.h was approximate.
11680 (allocate_string_data): Check for string overflow. This catches
11681 some instances we weren't catching before. Also, it catches
11682 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11683 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11684 and ptrdiff_t and EMACS_INT are both 64 bits.
11686 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11687 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
11688 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
11690 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
11692 * alloc.c (Fmake_string): Check for out-of-range init.
11694 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
11696 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
11698 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
11700 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
11701 xg_get_default_scrollbar_width.
11703 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
11704 (int_gtk_range_get_value): Move to the scroll bar part of the file.
11705 (style_changed_cb): Call update_theme_scrollbar_width and call
11706 x_set_scroll_bar_default_width and xg_frame_set_char_size for
11707 all frames (Bug#8505).
11708 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
11709 Call gtk_window_set_resizable if HAVE_GTK3.
11710 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
11711 and height if HAVE_GTK3 (Bug#8505).
11712 (scroll_bar_width_for_theme): New variable.
11713 (update_theme_scrollbar_width): New function.
11714 (xg_get_default_scrollbar_width): Move code to
11715 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
11716 (xg_initialize): Call update_theme_scrollbar_width.
11718 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
11720 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
11722 2011-06-12 Martin Rudalics <rudalics@gmx.at>
11724 * frame.c (make_frame): Call other_buffer_safely instead of
11727 * window.c (temp_output_buffer_show): Call display_buffer with
11728 second argument Vtemp_buffer_show_specifiers and reset latter
11729 immediately after the call.
11730 (Vtemp_buffer_show_specifiers): New variable.
11731 (auto_window_vscroll_p, next_screen_context_lines)
11732 (Vscroll_preserve_screen_position): Remove leading asterisks from
11735 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
11737 Fix minor problems found by GCC 4.6.0 static checking.
11738 * buffer.c (Qclone_number): Remove for now, as it's unused.
11739 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.

12183 (Fminibuffer_window): Move up in code.
12184 (Fwindow_minibuffer_p): Move up in code and simplify.
12185 (Fset_frame_selected_window): Move here from frame.c.
12187 (Fselected_window, select_window, Fselect_window): Move up in
12188 code. Minor doc-string fixes.
12190 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
12192 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
12193 Do not assume that spare memory exists; that assumption is valid
12194 only if SYSTEM_MALLOC.
12195 (LARGE_REQUEST): New macro, so that the issue of large requests
12196 is separated from the issue of spare memory.
12198 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
12200 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

12215 min width by calling x_set_scroll_bar_default_width (Bug#8505).
12217 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
12219 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
12221 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

12224 (x_clipboard_manager_save): Add return value.
12225 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
12226 New error handlers.
12227 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
12228 Obey Vx_select_enable_clipboard_manager. Catch errors in
12229 x_clipboard_manager_save (Bug#8779).
12230 (Vx_select_enable_clipboard_manager): New variable.
12231 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
12233 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
12235 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
12237 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12239 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
12240 in the current matrix if keep_current_p is non-zero.

12244 * bidi.c (bidi_level_of_next_char): Fix last change.
12246 2011-06-03 Eli Zaretskii <eliz@gnu.org>
12248 Support bidi reordering of text covered by display properties.
12250 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
12251 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
12252 (bidi_cache_search, bidi_cache_iterator_state)
12253 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12254 (bidi_level_of_next_char, bidi_move_to_visually_next):
12255 Support character positions inside a run of characters covered by a
12257 (bidi_paragraph_init, bidi_resolve_explicit_1)
12258 (bidi_level_of_next_char): Call bidi_fetch_char and
12259 bidi_fetch_char_advance instead of FETCH_CHAR and
12260 FETCH_CHAR_ADVANCE.
12261 (bidi_init_it): Initialize new members.
12262 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
12264 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
12265 instead of using explicit *_CHAR codes.
12266 (bidi_resolve_explicit, bidi_resolve_weak):
12267 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
12268 bidirectional text is supported only in multibyte buffers.
12269 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
12270 it to initialize the frame_window_p member of struct bidi_it.
12271 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
12272 (bidi_resolve_explicit, bidi_resolve_weak)

12274 bidi_it->nchars is non-positive.
12275 (bidi_level_of_next_char): Don't try to lookup the cache for the
12276 next/previous character if nothing is cached there yet, or if we
12277 were just reseat()'ed to a new position.
12279 * xdisp.c (set_cursor_from_row): Set start and stop points
12280 according to the row's direction when priming the loop that looks
12281 for the glyph on which to display cursor.
12282 (single_display_spec_intangible_p): Function deleted.
12283 (display_prop_intangible_p): Reimplement to call
12284 handle_display_spec instead of single_display_spec_intangible_p.
12285 Accept 3 additional arguments needed by handle_display_spec.
12286 This fixes incorrect cursor motion across display property with complex
12287 values: lists, `(when COND...)' forms, etc.
12288 (single_display_spec_string_p): Support property values that are
12289 lists with the argument STRING its top-level element.
12290 (display_prop_string_p): Fix the condition for processing a
12291 property that is a list to be consistent with handle_display_spec.
12292 (handle_display_spec): New function, refactored from the
12293 last portion of handle_display_prop.
12294 (compute_display_string_pos): Accept additional argument
12295 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
12296 value of a `display' property is a "replacing spec".
12297 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
12298 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
12299 the display property, but just return a value indicating whether
12300 the display property will replace the characters it covers.
12301 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
12302 frame_window_p members of struct bidi_it.
12303 (compute_display_string_pos, compute_display_string_end):
12305 (push_it): Accept second argument POSITION, where pop_it should
12306 jump to continue iteration.
12307 (reseat_1): Initialize bidi_it.disp_pos.
12309 * keyboard.c (adjust_point_for_property): Adjust the call to
12310 display_prop_intangible_p to its new signature.
12312 * dispextern.h (struct bidi_it): New member frame_window_p.
12313 (bidi_init_it): Update prototypes.
12314 (display_prop_intangible_p): Update prototype.
12315 (compute_display_string_pos, compute_display_string_end):
12316 Declare prototypes.
12317 (struct bidi_it): New members nchars and disp_pos. ch_len is now
12320 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
12322 Malloc failure behavior now depends on size of allocation.
12323 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
12324 * lisp.h: Change signatures accordingly.
12325 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
12326 All callers changed. (Bug#8762)
12328 * gnutls.c: Use Emacs's memory allocators.
12329 Without this change, the gnutls library would invoke malloc etc.
12330 directly, which causes problems on non-SYNC_INPUT hosts, and which
12331 runs afoul of improving memory_full behavior. (Bug#8761)
12332 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
12333 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
12334 xfree instead of the default malloc, realloc, free.
12335 (Fgnutls_boot): No need to check for memory allocation failure,
12336 since xmalloc does that for us.
12338 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
12339 * category.c (hash_get_category_set):
12340 * ccl.c (ccl_driver):
12341 * charset.c (Fdefine_charset_internal):
12342 * charset.h (struct charset.hash_index):
12343 * composite.c (get_composition_id, gstring_lookup_cache)
12344 (composition_gstring_put_cache):
12345 * composite.h (struct composition.hash_index):
12346 * dispextern.h (struct image.hash):
12347 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
12348 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
12349 (hashfn_equal, hashfn_user_defined, make_hash_table)
12350 (maybe_resize_hash_table, hash_lookup, hash_put)
12351 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
12352 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
12353 (Fsxhash, Fgethash, Fputhash, Fmaphash):
12354 * image.c (make_image, search_image_cache, lookup_image)
12355 (xpm_put_color_table_h):
12356 * lisp.h (struct Lisp_Hash_Table):
12357 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
12358 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
12359 for hashes and hash indexes, instead of 'unsigned' and 'int'.
12360 * alloc.c (allocate_vectorlike):
12361 Check for overflow in vector size calculations.
12362 * ccl.c (ccl_driver):
12363 Check for overflow when converting EMACS_INT to int.
12364 * fns.c, image.c: Remove unnecessary static decls that would otherwise
12365 need to be updated by these changes.
12366 * fns.c (make_hash_table, maybe_resize_hash_table):
12367 Check for integer overflow with large hash tables.
12368 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
12369 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
12370 (SXHASH_REDUCE): New macro.
12371 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
12372 Use it instead of discarding useful hash info with large hash values.
12373 (sxhash_float): New function.
12374 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
12375 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
12376 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
12377 Rewrite to use FIXNUM_BITS, as this simplifies things.
12378 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
12379 Adjust signatures to match updated version of code.
12380 (consing_since_gc): Now EMACS_INT, since a single hash table can
12381 use more than INT_MAX bytes.
12383 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
12385 Make it possible to build with GCC-4.6+ -O2 -flto.
12387 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
12389 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
12391 * minibuf.c (get_minibuffer, read_minibuf_unwind):
12392 Call minibuffer-inactive-mode.
12394 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
12396 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
12397 Update dependencies.
12399 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12401 * data.c (init_data): Remove code for UTS, this system is not
12404 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12406 Don't force ./temacs to start in terminal mode.
12408 * frame.c (make_initial_frame): Initialize faces in all cases, not
12409 only when CANNOT_DUMP is defined.
12410 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
12412 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12414 * dispnew.c (add_window_display_history): Use const for the string
12415 pointer. Remove declaration, not needed.
12417 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12419 Use 'inline', not 'INLINE'.
12420 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
12421 * alloc.c, fontset.c (INLINE): Remove.
12422 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
12423 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
12424 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
12425 * gmalloc.c (register_heapinfo): Use inline unconditionally.
12426 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
12428 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12430 Make it possible to run ./temacs.
12432 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
12433 syms_of_callproc does the same thing. Remove test for
12434 "initialized", do it in the caller.
12435 * emacs.c (main): Avoid calling set_initial_environment when dumping.
12437 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
12439 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
12440 (read_minibuf): Use get_minibuffer.
12441 (syms_of_minibuf): Use DEFSYM.
12442 (Qmetadata): New var.
12443 * data.c (Qbuffer): Don't make it static.
12444 (syms_of_data): Use DEFSYM.
12446 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12448 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
12449 (CCL_CODE_MIN): New macro.
12451 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
12453 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
12455 * eval.c (Qdebug): Now static.
12456 * lisp.h (Qdebug): Remove decl. This reverts a part of the
12457 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
12458 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
12460 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12462 * image.c: Various fixes to ImageMagick code comments.
12463 (Fimagemagick_types): Doc fix.
12465 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12467 Minor fixes prompted by GCC 4.6.0 warnings.
12469 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12471 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12472 (x_clipboard_manager_save_all): Move extern decl to ...
12473 * xterm.h: ... here, so that it can be checked for consistency.
12475 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12477 * xselect.c (x_clipboard_manager_save_frame)
12478 (x_clipboard_manager_save_all): New functions.
12479 (Fx_clipboard_manager_save): Lisp function deleted.
12481 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12482 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12484 * xterm.h: Update prototype.
12486 2011-05-28 William Xu <william.xwl@gmail.com>
12488 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12489 exiting (Bug#8239).
12491 2011-05-28 Jim Meyering <meyering@redhat.com>
12493 Avoid a sign-extension bug in crypto_hash_function.
12494 * fns.c (to_uchar): Define.
12495 (crypto_hash_function): Use it to convert some newly-signed
12496 variables to unsigned, to avoid sign-extension bugs. For example,
12497 without this change, (md5 "truc") would evaluate to
12498 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12499 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12500 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12502 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12504 Integer overflow fixes.
12506 * dbusbind.c: Serial number integer overflow fixes.
12507 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12508 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12509 to hold a serial number that is too large for a fixnum.
12510 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12511 Check for serial numbers out of range. Decode any serial number
12512 that was so large that it became a float. (Bug#8722)
12514 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12515 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12516 Use XFASTINT rather than XUINT when numbers are nonnegative.
12517 (xd_append_arg, Fdbus_method_return_internal):
12518 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12519 arguments, check that Lisp number is nonnegative, rather than
12520 silently wrapping negative numbers around. (Bug#8722)
12521 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12524 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12526 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12528 ccl: Add integer overflow checks.
12529 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12530 (IN_INT_RANGE): New macros.
12531 (ccl_driver): Use them to check for integer overflow when
12532 decoding a CCL program. Many of the new checks are whether XINT (x)
12533 fits in int; it doesn't always, on 64-bit hosts. The new version
12534 doesn't catch all possible integer overflows, but it's an
12535 improvement. (Bug#8719)
12537 * alloc.c (make_event_array): Use XINT, not XUINT.
12538 There's no need for unsigned here.
12540 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12541 This follows up to the 2011-05-06 change that substituted uintptr_t
12542 for EMACS_INT. This case wasn't caught back then.
12544 Rework Fformat to avoid integer overflow issues.
12545 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12546 now (part of C89). Include <verify.h>.
12547 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12548 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12549 (Fformat): Avoid the prepass trying to compute sizes; it was only
12550 approximate and thus did not catch overflow reliably. Instead, walk
12551 through the format just once, formatting and computing sizes as we go,
12552 checking for integer overflow at every step, and allocating a larger
12553 buffer as needed. Keep track separately whether the format is
12554 multibyte. Keep only the most-recently calculated precision, rather
12555 than them all. Record whether each argument has been converted to
12556 string. Use EMACS_INT, not int, for byte and char and arg counts.
12557 Support field widths and precisions larger than INT_MAX. Avoid
12558 sprintf's undefined behavior with conversion specifications such as %#d
12559 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12560 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12561 formatting out-of-range floating point numbers with int
12562 formats. (Bug#8668)
12564 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12566 * data.c: Avoid integer truncation in expressions involving floats.
12567 * data.c: Include <intprops.h>.
12568 (arith_driver): When there's an integer overflow in an expression
12569 involving floating point, convert the integers to floating point
12570 so that the resulting value does not suffer from catastrophic
12571 integer truncation. For example, on a 64-bit host (* 4
12572 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12573 Do not rely on undefined behavior after integer overflow.
12575 merge count_size_as_multibyte, parse_str_to_multibyte
12576 * character.c, character.h (count_size_as_multibyte):
12577 Rename from parse_str_to_multibyte; all uses changed.
12578 Check for integer overflow.
12579 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12580 since it's now a duplicate of the other. This is more of
12581 a character than a buffer op, so better that it's in character.c.
12582 * fns.c, print.c: Adjust to above changes.
12584 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12586 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12588 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12590 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12591 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12592 (x_clipboard_manager_save): Now static.
12593 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12595 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12596 (crypto_hash_function): Now static.
12597 Fix pointer signedness problems. Avoid unnecessary initializations.
12599 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12601 * termhooks.h (Vselection_alist): Make it terminal-local.
12603 * terminal.c (create_terminal): Initialize it.
12605 * xselect.c: Support for clipboard managers.
12606 (Vselection_alist): Move to termhooks.h as terminal-local var.
12607 (LOCAL_SELECTION): New macro.
12608 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12609 (symbol_to_x_atom): Remove gratuitous arg.
12610 (x_handle_selection_request, lisp_data_to_selection_data)
12611 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12612 (x_own_selection, x_get_local_selection, x_convert_selection):
12613 New arg, specifying work frame. Use terminal-local Vselection_alist.
12614 (some_frame_on_display): Delete unused function.
12615 (Fx_own_selection_internal, Fx_get_selection_internal)
12616 (Fx_disown_selection_internal, Fx_selection_owner_p)
12617 (Fx_selection_exists_p): New optional frame arg.
12618 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12619 (x_handle_selection_clear): Don't treat other terminals with the
12620 same keyboard specially. Use the terminal-local Vselection_alist.
12621 (x_clear_frame_selections): Use Frun_hook_with_args.
12623 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12625 * xterm.h: Add support for those atoms.
12627 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12629 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12630 (converted_selections, conversion_fail_tag): New global variables.
12631 (x_selection_request_lisp_error): Free the above.
12632 (x_get_local_selection): Remove unnecessary code.
12633 (x_reply_selection_request): Args changed; handle arbitrary array
12634 of converted selections stored in converted_selections.
12635 Separate the XChangeProperty and SelectionNotify steps.
12636 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12637 (x_convert_selection): New function.
12638 (x_handle_selection_event): Simplify.
12639 (x_get_foreign_selection): Don't ignore incoming requests while
12640 waiting for an answer; this will fail when we implement
12641 SAVE_TARGETS, and seems unnecessary anyway.
12642 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12643 (Vx_sent_selection_functions): Doc fix.
12645 2011-05-26 Leo Liu <sdl.web@gmail.com>
12647 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12649 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12651 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12653 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12654 for fringe update if it has periodic bitmap.
12655 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12656 and fringe_bitmap_periodic_p.
12658 * fringe.c (get_fringe_bitmap_data): New function.
12659 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12660 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12661 row. Mark glyph row for fringe update if periodicity changed.
12663 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12664 for fringe update unless it has periodic bitmap.
12666 2011-05-25 Kenichi Handa <handa@m17n.org>
12668 * xdisp.c (get_next_display_element): Set correct it->face_id for
12669 a static composition.
12671 2011-05-24 Leo Liu <sdl.web@gmail.com>
12674 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12676 * fns.c (crypto_hash_function, Fsha1): New function.
12677 (Fmd5): Use crypto_hash_function.
12678 (syms_of_fns): Add Ssha1.
12680 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12682 * gnutls.c: Remove unused macros.
12683 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12684 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12685 Remove macros that are defined and never used.
12686 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12688 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12690 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12691 (Fx_get_selection_internal): Minor cleanup.
12692 (Fx_own_selection_internal): Rename arguments for consistency with
12695 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12697 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12699 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12701 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12703 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12705 * dispnew.c (scrolling_window): Don't exclude the case that the
12706 last enabled row in the desired matrix touches the bottom boundary.
12708 2011-05-21 Glenn Morris <rgm@gnu.org>
12710 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12711 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12712 and add some more files.
12714 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12716 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12717 report_file_error introduced by the change from 2011-05-07.
12719 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12721 * systime.h (Time): Define only if emacs is defined.
12722 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12723 where the include path doesn't have X11/X.h by default. See
12724 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12726 2011-05-20 Kenichi Handa <handa@m17n.org>
12728 * composite.c (find_automatic_composition): Fix previous change.
12730 2011-05-20 Glenn Morris <rgm@gnu.org>
12732 * lisp.mk: New file, split from Makefile.in.
12733 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12734 (shortlisp): Remove.
12735 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12737 2011-05-19 Glenn Morris <rgm@gnu.org>
12739 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12740 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12741 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12742 (lisp): Set the order to that of loadup.el.
12743 (shortlisp): Make it a copy of $lisp.
12744 (SOME_MACHINE_LISP): Remove.
12745 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12746 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12748 2011-05-18 Kenichi Handa <handa@m17n.org>
12750 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12751 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12752 (find_automatic_composition): Mostly rewrite for efficiency.
12754 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12756 * makefile.w32-in: Update dependencies.
12758 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12760 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12761 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12763 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12765 Fix some integer overflow issues, such as string length overflow.
12767 * insdel.c (count_size_as_multibyte): Check for string overflow.
12769 * character.c (lisp_string_width): Check for string overflow.
12770 Use EMACS_INT, not int, for string indexes and lengths; in
12771 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12772 the resulting string length overflows an EMACS_INT; instead,
12773 report a string overflow if no precision given. When checking for
12774 precision exhaustion, use a check that cannot possibly have
12775 integer overflow. (Bug#8675)
12776 * character.h (lisp_string_width): Adjust to new signature.
12778 * alloc.c (string_overflow): New function.
12779 (Fmake_string): Use it. This doesn't change behavior, but saves
12780 a few bytes and will simplify future changes.
12781 * character.c (string_escape_byte8): Likewise.
12782 * lisp.h (string_overflow): New decl.
12784 Fixups, following up to the user-interface timestamp change.
12785 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12786 for UI timestamps, instead of unsigned long.
12787 * msdos.c (mouse_get_pos): Likewise.
12788 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12789 * w32gui.h (Time): Define by including "systime.h" rather than by
12790 declaring it ourselves. (Bug#8664)
12792 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12793 * image.c (clear_image_cache): Likewise.
12795 * term.c (term_mouse_position): Don't assume time_t wraparound.
12797 Be more systematic about user-interface timestamps.
12798 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12799 and sometimes 'EMACS_UINT', to represent these timestamps.
12800 This change causes it to use 'Time' uniformly, as that's what X uses.
12801 This makes the code easier to follow, and makes it easier to catch
12802 integer overflow bugs such as Bug#8664.
12803 * frame.c (Fmouse_position, Fmouse_pixel_position):
12804 Use Time, not unsigned long, for user-interface timestamps.
12805 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12806 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12807 * keyboard.h (last_event_timestamp): Likewise.
12808 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12809 * menu.h (xmenu_show): Likewise.
12810 * term.c (term_mouse_position): Likewise.
12811 * termhooks.h (struct input_event.timestamp): Likewise.
12812 (struct terminal.mouse_position_hook): Likewise.
12813 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12814 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12815 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12816 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12817 what it was before.
12818 * menu.h, termhooks.h: Include "systime.h", for Time.
12820 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12821 Don't assume that the difference between two unsigned long values
12822 can fit into an integer. At this point, we know button_down_time
12823 <= event->timestamp, so the difference must be nonnegative, so
12824 there's no need to cast the result if double-click-time is
12825 nonnegative, as it should be; check that it's nonnegative, just in
12826 case. This bug is triggered when events are more than 2**31 ms
12827 apart (about 25 days). (Bug#8664)
12829 * xselect.c (last_event_timestamp): Remove duplicate decl.
12830 (x_own_selection): Remove needless cast to unsigned long.
12832 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12833 that always fit in int. Use a sentinel instead of a counter, to
12834 avoid a temp and to allay GCC's concerns about possible int overflow.
12835 * frame.h (struct frame): Use int for menu_bar_items_used
12836 instead of EMACS_INT, since it always fits in int.
12838 * menu.c (grow_menu_items): Check for int overflow.
12840 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12842 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12843 Before, the code was not consistent. These values cannot exceed
12844 2**31 - 1 so there's no need to make them unsigned.
12845 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12846 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12847 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12849 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12851 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12852 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12853 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12854 presumably because the widths might not match.
12856 * window.c (size_window): Avoid needless test at loop start.
12858 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12860 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12862 2011-05-12 Drew Adams <drew.adams@oracle.com>
12864 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12866 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12868 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12869 `width' to `bar_area_x' and `bar_area_width', respectively.
12870 (x_scroll_run): Take account of fringe background extension.
12872 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12873 Rename local vars `left' and `width' to `bar_area_x' and
12874 `bar_area_width', respectively.
12875 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12876 background extension.
12878 2011-05-10 Jim Meyering <meyering@redhat.com>
12880 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12882 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12884 * image.c (Finit_image_library): Return t for built-in image types,
12885 like pbm and xbm. (Bug#8640)
12887 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12889 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12891 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12893 * w32console.c (Fset_screen_color): Doc fix.
12894 (Fget_screen_color): New function.
12895 (syms_of_ntterm): Defsubr it.
12897 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12898 unlink the temporary file if Fcall_process didn't create it in the
12900 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12901 child process will be redirected to a file specified with `:file'.
12902 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12903 cue to call_process_cleanup not to close that handle.
12905 2011-05-07 Ben Key <bkey76@gmail.com>
12907 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12908 one of two shell specific rules, either bootstrap-temacs-CMD or
12909 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12910 to the previous implementation of the bootstrap-temacs rule.
12911 The bootstrap-temacs-CMD rule is similar to the previous
12912 implementation of the bootstrap-temacs rule except that it
12913 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12916 These changes, along with some changes to nt/configure.bat,
12917 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12918 earlier fix to add support for --cflags and --ldflags options
12919 that include quotes so that it works whether make uses cmd or
12922 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12924 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12925 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12927 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12928 a string. Handle both cases.
12929 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12930 (Fdbus_register_method): Use Qinvalid_function.
12932 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12934 * makefile.w32-in: Update dependencies.
12935 (LISP_H): Add inttypes.h and stdin.h.
12936 (PROCESS_H): Add unistd.h.
12938 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12940 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12941 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12943 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12945 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12947 * term.c (vfatal): Remove stray call to va_end.
12948 It's not needed and the C Standard doesn't allow it here anyway.
12950 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12951 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12953 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12956 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12958 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12960 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12962 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12964 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12966 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12967 * charset.c (Fdefine_charset_internal): Don't initialize
12968 charset.code_space[15]. The value was garbage, on hosts with
12969 32-bit int (Bug#8600).
12971 * lread.c (read_integer): Be more consistent with string-to-number.
12972 Use string_to_number to do the actual conversion; this avoids
12973 rounding errors and fixes some other screwups. Without this fix,
12974 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12975 (digit_to_number): Move earlier, for benefit of read_integer.
12976 Return -1 if the digit is out of range for the base, -2 if it is
12977 not a digit in any supported base. (Bug#8602)
12979 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12981 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12982 to match comment at start of function. This also removes a
12983 GCC warning about overflow in a 32+64-bit port.
12985 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12987 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12988 Reported by Stefan Monnier in
12989 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12990 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12991 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12993 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12994 (EMACS_UINTPTR): Likewise, with uintptr_t.
12996 * lisp.h: Prefer 64-bit EMACS_INT if available.
12997 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12998 on 32-bit hosts that have 64-bit int, so that they can access
13000 However, temporarily disable this change unless the temporary
13001 symbol WIDE_EMACS_INT is defined.
13003 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
13005 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
13006 This removes an assumption that EMACS_INT and long are the same
13007 width as pointers. The assumption is true for Emacs porting targets
13008 now, but we want to make other targets possible.
13009 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
13010 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
13011 In the rest of the code, change types of integers that hold casted
13012 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
13013 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
13014 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
13015 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
13016 No need to cast type when ORing.
13017 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
13018 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
13019 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
13020 assume EMACS_INT is the same width as char *.
13021 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
13022 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
13023 Remove no-longer-needed casts.
13024 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
13025 (xg_tool_bar_help_callback, xg_make_tool_item):
13026 Use EMACS_INTPTR to hold an integer
13027 that will be cast to void *; this can avoid a GCC warning
13028 if EMACS_INT is not the same width as void *.
13029 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
13030 * xdisp.c (display_echo_area_1, resize_mini_window_1):
13031 (current_message_1, set_message_1):
13032 Use a local to convert to proper width without a cast.
13033 * xmenu.c (dialog_selection_callback): Likewise.
13035 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
13036 Also, don't assume VALBITS / RAND_BITS is less than 5,
13037 and don't rely on undefined behavior when shifting a 1 left into
13039 * lisp.h (get_random): Change signature to match.
13041 * lread.c (hash_string): Use size_t, not int, for hash computation.
13042 Normally we prefer signed values; but hashing is special, because
13043 it's better to use unsigned division on hash table sizes so that
13044 the remainder is nonnegative. Also, size_t is the natural width
13045 for hashing into memory. The previous code used 'int', which doesn't
13046 retain enough info to hash well into very large tables.
13047 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
13049 * dbusbind.c: Don't possibly lose pointer info when converting.
13050 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13051 Use XPNTR rather than XHASH, so that the high-order bits of
13052 the pointer aren't lost when converting through void *.
13054 * eval.c (Fautoload): Don't double-shift a pointer.
13056 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

13065 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
13068 2011-05-05 Eli Zaretskii <eliz@gnu.org>
13070 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:

13090 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
13091 Remove unused parameter `fildes'.
13092 * process.c (read_process_output, send_process): Don't pass it.
13094 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
13096 Fix previous change: the library cache is defined in w32.c.
13097 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
13098 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

13132 * w32.c (QCloaded_from, Vlibrary_cache): Define.
13133 (w32_delayed_load): Move from image.c. When loading a library, record
13134 its filename in the :loaded-from property of the library id.
13135 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
13136 Initialize and staticpro them.
13137 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
13139 * process.c: Include lisp.h before w32.h, not after.
13140 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
13141 instead of gnutls_record_check_pending.
13143 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
13145 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
13147 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
13148 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
13151 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
13153 * xterm.c (x_set_frame_alpha): Do not set property on anything
13154 else than FRAME_X_OUTER_WINDOW (Bug#8608).
13156 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
13158 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
13160 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
13162 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

13188 (Fcall_process_region): Ditto.
13190 2011-04-30 Eli Zaretskii <eliz@gnu.org>
13192 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
13193 rather than `XVECTOR (FOO)->size'.
13195 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
13196 inttypes.h, as a gnulib replacement is used if it not available in
13199 2011-04-21 Eli Zaretskii <eliz@gnu.org>
13201 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
13202 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
13203 of MOST_POSITIVE_FIXNUM. (Bug#8528)
13205 * coding.c (coding_alloc_by_realloc): Error out if destination
13206 will grow beyond MOST_POSITIVE_FIXNUM.
13207 (decode_coding_emacs_mule): Abort if there isn't enough place in
13208 charbuf for the composition carryover bytes. Reserve an extra
13209 space for up to 2 characters produced in a loop.

13211 charbuf for the composition carryover bytes.
13213 2011-04-21 Eli Zaretskii <eliz@gnu.org>
13215 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
13216 aborting when %lld or %lll format is passed.

13218 %llo or %llx format is passed. (Bug#8545)
13220 * window.c (window_scroll_line_based): Use a marker instead of
13221 simple variables to record original value of point. (Bug#7952)
13223 * doprnt.c (doprnt): Fix the case where a multibyte sequence
13224 produced by %s or %c overflows available buffer space. (Bug#8545)
13226 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
13228 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

13231 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

13238 (command_loop_1): Run `delayed-warnings-hook'
13239 if Vdelayed_warnings_list is non-nil.
13240 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
13241 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.

13245 * doprnt.c (doprnt): Don't return value smaller than the buffer
13246 size if the message was truncated. (Bug#8545).

13250 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

13261 2011-04-27 Eli Zaretskii <eliz@gnu.org>
13263 Improve `doprnt' and its usage. (Bug#8545)
13264 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
13265 `format_end'. Remove support for %l as a conversion specifier.
13266 Don't use xrealloc. Improve diagnostics when the %l size modifier
13267 is used. Update the commentary.
13269 * eval.c (verror): Simplify calculation of size_t.
13271 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
13274 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
13276 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
13279 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
13281 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
13282 This makes this file independent of the recent pseudovector change.
13284 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
13286 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
13288 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
13289 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
13290 Remove unused local.
13291 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
13293 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
13294 GCC 4.6.0 optimizes based on type-based alias analysis.
13295 For example, if b is of type struct buffer * and v of type struct
13296 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
13297 != &v->size, and therefore "v->size = 1; b->size = 2; return
13298 v->size;" must therefore return 1. This assumption is incorrect
13299 for Emacs, since it type-puns struct Lisp_Vector * with many other
13300 types. To fix this problem, this patch adds a new type struct
13301 vectorlike_header that documents the constraints on layout of vectors
13302 and pseudovectors, and helps optimizing compilers not get fooled
13303 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
13304 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
13305 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
13307 (XSETPVECTYPE): Rewrite in terms of new macro.
13308 (XSETPVECTYPESIZE): New macro, specifying both type and size.
13309 This is a bit clearer, and further avoids the possibility of
13310 undesirable aliasing.
13311 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
13312 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
13313 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
13314 since Lisp_Subr is a special case (no "next" field).
13315 (ASIZE): Now uses header.size rather than size.
13316 All previous uses of XVECTOR (foo)->size replaced to use this macro,
13317 to avoid the hassle of writing XVECTOR (foo)->header.size.
13318 (struct vectorlike_header): New type.
13319 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
13320 object, to help avoid aliasing.
13321 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
13322 (SUBRP): Likewise, since Lisp_Subr is a special case.
13323 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
13324 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
13325 (struct Lisp_Hash_Table): Combine first two members into a single
13326 struct vectorlike_header member. All uses of "size" and "next" members
13327 changed to be "header.size" and "header.next".
13328 * buffer.h (struct buffer): Likewise.
13329 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
13330 * frame.h (struct frame): Likewise.
13331 * process.h (struct Lisp_Process): Likewise.
13332 * termhooks.h (struct terminal): Likewise.
13333 * window.c (struct save_window_data, struct saved_window): Likewise.
13334 * window.h (struct window): Likewise.
13335 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
13336 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
13337 * buffer.c (init_buffer_once): Likewise.
13338 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
13340 * process.c (Fformat_network_address): Use local var for size,
13343 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
13345 Make the Lisp reader and string-to-float more consistent (Bug#8525)
13346 * data.c (atof): Remove decl; no longer used or needed.
13347 (digit_to_number): Move to lread.c.
13348 (Fstring_to_number): Use new string_to_number function, to be
13349 consistent with how the Lisp reader treats infinities and NaNs.
13350 Do not assume that floating-point numbers represent EMACS_INT
13351 without losing information; this is not true on most 64-bit hosts.
13352 Avoid double-rounding errors, by insisting on integers when
13353 parsing non-base-10 numbers, as the documentation specifies.
13354 * lisp.h (string_to_number): New decl, replacing ...
13355 (isfloat_string): Remove.
13356 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
13357 (read1): Do not accept +. and -. as integers; this
13358 appears to have been a coding error. Similarly, do not accept
13359 strings like +-1e0 as floating point numbers. Do not report
13360 overflow for integer overflows unless the base is not 10 which
13361 means we have no simple and reliable way to continue.
13362 Break out the floating-point parsing into a new
13363 function string_to_number, so that Fstring_to_number parses
13364 floating point numbers consistently with the Lisp reader.
13365 (digit_to_number): Move here from data.c. Make it static inline.
13366 (E_CHAR, EXP_INT): Remove, replacing with ...
13367 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
13368 (string_to_number): New function, replacing isfloat_string.
13369 This function checks for valid syntax and produces the resulting
13370 Lisp float number too. Rework it so that string-to-number
13371 no longer mishandles examples like "1.0e+". Use strtoumax,
13372 so that overflow for non-base-10 numbers is reported only when
13373 there's no portable and simple way to convert to floating point.
13375 * textprop.c (set_text_properties_1): Rewrite for clarity,
13376 and to avoid GCC warning about integer overflow.
13378 * intervals.h (struct interval): Use EMACS_INT for members
13379 where EMACS_UINT might cause problems. See
13380 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
13381 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
13382 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
13384 (offset_intervals): Tell GCC not to worry about length overflow
13385 when negating a negative length.
13387 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
13388 (overrun_check_free): Likewise.
13390 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
13391 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
13394 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13395 (gnutls_make_error): Rename local to avoid shadowing.
13396 (gnutls_emacs_global_deinit): ifdef out; not used.
13397 (Fgnutls_boot): Use const for pointer to readonly storage.
13398 Comment out unused local. Fix pointer signedness problems.
13400 * lread.c (openp): Don't stuff size_t into an 'int'.
13401 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
13402 about possible signed overflow.
13404 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13405 (GDK_KEY_g): Don't define if already defined.
13406 (xg_prepare_tooltip): Avoid pointer signedness problem.
13407 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
13409 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
13410 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
13412 * xfns.c (Fx_window_property): Simplify a bit,
13413 to make a bit faster and to avoid GCC 4.6.0 warning.
13414 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
13416 * fns.c (internal_equal): Don't assume size_t fits in int.
13418 * alloc.c (compact_small_strings): Tighten assertion a little.
13420 Replace pEd with more-general pI, and fix some printf arg casts.
13421 * lisp.h (pI): New macro, generalizing old pEd macro to other
13422 conversion specifiers. For example, use "...%"pI"d..." rather
13423 than "...%"pEd"...".
13424 (pEd): Remove. All uses replaced with similar uses of pI.
13425 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
13426 * alloc.c (check_pure_size): Don't overflow by converting size to int.
13427 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
13428 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
13429 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
13430 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
13431 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
13433 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
13434 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
13435 * print.c (safe_debug_print, print_object): Likewise.
13436 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
13438 Use pI instead of if-then-else-abort. Use %p to avoid casts,
13439 avoiding the 0 flag, which is not portable.
13440 * process.c (Fmake_network_process): Use pI to avoid cast.
13441 * region-cache.c (pp_cache): Likewise.
13442 * xdisp.c (decode_mode_spec): Likewise.
13443 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13444 behavior on 64-bit hosts with printf arg.
13445 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
13446 (x_stop_queuing_selection_requests): Likewise.
13447 (x_get_window_property): Don't truncate byte count to an 'int'
13450 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13451 here, since it parses constructs like leading '-' and spaces,
13452 which are not wanted; and it overflows with large numbers.
13453 Instead, simply match F[0-9]+, which is what is wanted anyway.
13455 * alloc.c: Remove unportable assumptions about struct layout.
13456 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13457 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13458 (allocate_vectorlike, make_pure_vector): Use the new macros,
13459 plus offsetof, to remove unportable assumptions about struct layout.
13460 These assumptions hold on all porting targets that I know of, but
13461 they are not guaranteed, they're easy to remove, and removing them
13462 makes further changes easier.
13464 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13465 This doesn't fix a bug but makes the code clearer.
13466 (string_overrun_cookie): Now const. Use initializers that
13467 don't formally overflow signed char, to avoid warnings.
13468 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
13469 can cause Emacs to crash when string overrun checking is enabled.
13470 (allocate_buffer): Don't assume sizeof (struct buffer) is a

13509 supported by the function. Use SAFE_ALLOCA instead of always
13512 * eval.c (verror): Don't limit the buffer size at size_max-1, that
13513 is one byte too soon. Don't use xrealloc; instead xfree and

13641 to `error' in error message about FINAL_CHAR argument. Make sure
13642 FINAL_CHAR is a character, and use %c when it is passed as
13643 argument to `error'.
13645 2011-04-23 Eli Zaretskii <eliz@gnu.org>
13647 * s/ms-w32.h (localtime): Redirect to sys_localtime.
13649 * w32.c: Include <time.h>.

13713 * dispextern.h (struct redisplay_interface): Rename param
13714 to avoid shadowing.

13832 * nsfont.m: Fixed bugs in ns_get_family and
13833 ns_descriptor_to_entity that were caused by using free to
13834 deallocate memory blocks that were allocated by xmalloc (via
13835 xstrdup). This caused Emacs to crash when compiled with
13836 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
13837 --enable-checking=xmallocoverrun). xfree is now used to
13838 deallocate these memory blocks.

13855 (emacs_read, emacs_write): Use it.
13856 * process.c (send_process): Adjust to the new signatures of
13857 emacs_write and emacs_gnutls_write. Do not attempt to store

14350 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
14352 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
14354 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
14356 Fix more problems found by GCC 4.6.0's static checks.
14358 * xdisp.c (vmessage): Use a better test for character truncation.
14360 * charset.c (load_charset_map): <, not <=, for optimization,
14361 and to avoid potential problems with integer overflow.
14362 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
14363 * casetab.c (set_identity, shuffle): Likewise.
14364 * editfns.c (Fformat): Likewise.
14365 * syntax.c (skip_chars): Likewise.
14367 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
14368 This also lets GCC 4.6.0 generate slightly better loop code.
14370 * callint.c (Fcall_interactively): <, not <=, for optimization.
14371 (Fcall_interactively): Count the number of arguments produced,
14372 not the number of arguments given. This is simpler and lets GCC
14373 4.6.0 generate slightly better code.
14375 * ftfont.c: Distingish more carefully between FcChar8 and char.
14376 The previous code passed unsigned char * to a functions like
14377 strlen and xstrcasecmp that expect char *, which does not
14378 conform to the C standard.
14379 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
14380 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
14381 char * when the C standard requires it.
14383 * keyboard.c (read_char): Remove unused var.
14385 * eval.c: Port to Windows vsnprintf (Bug#8435).
14386 Include <limits.h>.
14387 (SIZE_MAX): Define if the headers do not.
14388 (verror): Do not give up if vsnprintf returns a negative count.
14389 Instead, grow the buffer. This ports to Windows vsnprintf, which
14390 does not conform to C99. Problem reported by Eli Zaretskii.
14391 Also, simplify the allocation scheme, by avoiding the need for
14392 calling realloc, and removing the ALLOCATED variable.
14394 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
14396 Remove invocations of doprnt, as Emacs now uses vsnprintf.
14397 But keep the doprint source code for now, as we might revamp it
14398 and use it again (Bug#8435).
14399 * lisp.h (doprnt): Remove.
14400 * Makefile.in (base_obj): Remove doprnt.o.
14401 * deps.mk (doprnt.o): Remove.
14403 error: Print 32- and 64-bit integers portably (Bug#8435).
14404 Without this change, on typical 64-bit hosts error ("...%d...", N)
14405 was used to print both 32- and 64-bit integers N, which relied on
14406 undefined behavior.
14407 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
14408 * lisp.h (error, verror): Mark as printf-like functions.
14409 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
14410 Report overflow in size calculations when allocating printf buffer.
14411 Do not truncate output string at its first null byte.
14412 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
14413 Truncate the output at a character boundary, since vsnprintf does not
14415 * charset.c (check_iso_charset_parameter): Convert internal
14416 character to string before calling 'error', since %c now has the
14418 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
14419 overflow when computing char to be passed to 'error'. Do not
14420 pass Lisp_Object to 'error'; pass the integer instead.
14421 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
14422 formatted with plain %d.
14424 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
14426 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
14428 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
14430 * xterm.c (x_catch_errors): Remove duplicate declaration.
14432 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
14434 * xdisp.c, lisp.h (message_nolog): Remove; unused.
14436 2011-04-10 Jim Meyering <meyering@redhat.com>
14438 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
14439 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
14440 return ssize_t not "int", and use size_t as the buffer length.
14441 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14442 * gnutls.h: Update declarations.
14443 * process.c (read_process_output): Use ssize_t, to match.
14444 (send_process): Likewise.
14446 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14448 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14450 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14452 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14453 Use unsigned char, to match FcChar8 type definition.
14455 * xterm.c (handle_one_xevent):
14456 * xmenu.c (create_and_show_popup_menu):
14457 * xselect.c (x_decline_selection_request)
14458 (x_reply_selection_request): Avoid type-punned deref of X events.
14460 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14462 Fix some uses of `int' instead of EMACS_INT.
14463 * search.c (string_match_1, fast_string_match)
14464 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
14465 (scan_buffer, find_next_newline_no_quit)
14466 (find_before_next_newline, search_command, Freplace_match)
14467 (Fmatch_data): Make some `int' variables be EMACS_INT.
14469 * xdisp.c (display_count_lines): 3rd argument and return value now
14470 EMACS_INT. All callers changed.
14471 (pint2hrstr): Last argument is now EMACS_INT.
14473 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
14474 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
14475 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
14476 (decode_coding_utf_16, decode_coding_emacs_mule)
14477 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
14478 (decode_coding_ccl, decode_coding_charset)
14479 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
14480 (decode_coding_iso_2022, decode_coding_emacs_mule)
14481 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
14482 <char_offset, last_offset>: Declare EMACS_INT.
14483 (encode_coding_utf_8, encode_coding_utf_16)
14484 (encode_coding_emacs_mule, encode_invocation_designation)
14485 (encode_designation_at_bol, encode_coding_iso_2022)
14486 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
14487 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
14489 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
14490 (encode_invocation_designation): Last argument P_NCHARS is now
14492 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
14493 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
14495 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
14498 * ccl.c (Fccl_execute_on_string): Declare some variables
14501 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
14503 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
14505 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
14507 * process.c (Fformat_network_address): Doc fix.
14509 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
14511 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
14513 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
14515 * keyboard.c (read_char): Call Lisp function help-form-show,
14516 instead of using internal_with_output_to_temp_buffer.
14517 (Qhelp_form_show): New var.
14518 (syms_of_keyboard): Use DEFSYM macro.
14520 * print.c (internal_with_output_to_temp_buffer): Function deleted.
14522 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
14524 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
14526 * process.c (Flist_processes): Remove to Lisp.
14527 (list_processes_1): Delete.
14529 2011-04-06 Eli Zaretskii <eliz@gnu.org>
14531 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
14533 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
14535 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
14537 Fix more problems found by GCC 4.6.0's static checks.
14539 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
14541 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
14543 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14545 * xdisp.c (vmessage): Mark as a printf-like function.
14547 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
14549 * sound.c (sound_warning): Don't crash if arg contains a printf format.
14551 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
14552 printf-like functions.
14553 (tiff_load): Add casts to remove these marks before passing them
14554 to system-supplied API.
14556 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14558 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14559 This avoids several warnings with gcc -Wstrict-overflow.
14560 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14561 directly, rather than having caller test rule sign. This avoids
14562 some unnecessary tests.
14563 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14564 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14565 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14567 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14568 (xfont_open): Avoid unnecessary tests.
14570 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14572 * composite.h, composite.c (composition_gstring_put_cache):
14573 Use EMACS_INT, not int, for length.
14575 * composite.h (COMPOSITION_DECODE_REFS): New macro,
14576 breaking out part of COMPOSITION_DECODE_RULE.
14577 (COMPOSITION_DECODE_RULE): Use it.
14578 * composite.c (get_composition_id): Remove unused local vars,
14579 by using the new macro.
14581 * textprop.c (set_text_properties_1): Change while to do-while,
14582 since the condition is always true at first.
14584 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14585 (interval_deletion_adjustment): Return unsigned value.
14588 * process.c (list_processes_1, create_pty, read_process_output):
14589 (exec_sentinel): Remove vars that were set but not used.
14590 (create_pty): Remove unnecessary "volatile"s.
14591 (Fnetwork_interface_info): Avoid possibility of int overflow.

14598 (update_syntax_table): Use unsigned instead of int.
14600 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14601 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14602 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14604 * print.c (print_error_message): Avoid int overflow.
14606 * font.c (font_list_entities): Redo for clarity,
14607 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14609 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14610 (font_score): Avoid potential overflow in diff calculation.
14612 * fns.c (substring_both): Remove var that is set but not used.
14613 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14615 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14617 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14618 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14619 can always succeed if overflow has undefined behavior.
14621 * search.c (boyer_moore, wordify): Remove vars set but not used.
14622 (wordify): Omit three unnecessary tests.
14624 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14625 All callers changed. This avoids the need for an unused var.
14627 * casefiddle.c (casify_region): Remove var that is set but not used.
14629 * dired.c (file_name_completion): Remove var that is set but not used.
14631 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14633 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14634 (Finsert_file_contents): Remove unnecessary code checking fd.
14636 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14637 Check for integer overflow on size calculations.
14639 * buffer.c (Fprevious_overlay_change): Remove var that is set
14642 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14643 Remove vars that are set but not used.
14644 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14645 (timer_check_2): Mark vars as initialized.
14647 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14649 * image.c (lookup_image): Remove var that is set but not used.
14650 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14652 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14653 that are set but not used.
14655 * xfns.c (make_invisible_cursor): Don't return garbage
14656 if XCreateBitmapFromData fails (Bug#8410).
14658 * xselect.c (x_get_local_selection, x_handle_property_notify):
14659 Remove vars that are set but not used.
14661 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
14662 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
14664 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
14665 Remove var that is set but not used.
14666 (scroll_bar_windows_size): Now size_t, not int.
14667 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
14668 Check for overflow.
14670 * xfaces.c (realize_named_face): Remove vars that are set but not used.
14671 (map_tty_color) [!defined MSDOS]: Likewise.
14673 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14675 * coding.c: Remove vars that are set but not used.
14676 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14677 All callers changed.
14678 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
14679 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
14680 (decode_coding_charset): Remove vars that are set but not used.
14682 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
14683 that is set but not used.
14685 * print.c (print_object): Remove var that is set but not used.
14687 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14688 The gnulib version avoids calling malloc in the usual case,
14689 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14690 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14691 * filelock.c (current_lock_owner): Likewise.
14692 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14693 * sysdep.c: Include allocator.h, careadlinkat.h.
14694 (emacs_no_realloc_allocator): New static constant.
14695 (emacs_readlink): New function.
14696 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14697 ../lib/careadlinkat.h.
14699 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14701 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14702 first non-nil return value).
14704 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
14706 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
14707 if not defined (Bug#8403).
14709 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14711 * xdisp.c (display_count_lines): Remove parameter `start',
14712 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

14714 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
14715 (fill_stretch_glyph_string): Remove parameters `row' and `area',
14716 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
14717 and thereabouts. All callers changed.
14718 (get_per_char_metric): Remove parameter `f', unused since
14719 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
14721 2011-04-02 Jim Meyering <meyering@redhat.com>
14723 do not dereference NULL upon failed strdup
14724 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14725 (ns_get_family): Likewise.
14727 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14729 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
14731 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
14733 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
14736 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
14738 Add lexical binding.
14740 * window.c (Ftemp_output_buffer_show): New fun.
14741 (Fsave_window_excursion):

14744 * lread.c (lisp_file_lexically_bound_p): New function.
14745 (Fload): Bind Qlexical_binding.
14746 (readevalloop): Remove `evalfun' arg.
14747 Bind Qinternal_interpreter_environment.

14749 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
14751 (syms_of_lread): Declare `lexical-binding'.
14753 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
14755 * keyboard.c (eval_dyn): New fun.
14756 (menu_item_eval_property): Use it.
14758 * image.c (parse_image_spec): Use Ffunctionp.
14760 * fns.c (concat, mapcar1): Accept byte-code-functions.
14762 * eval.c (Fsetq): Handle lexical vars.
14763 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
14764 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
14765 (FletX, Flet): Obey lexical binding.
14766 (Fcommandp): Handle closures.
14767 (Feval): New `lexical' arg.
14768 (eval_sub): New function extracted from Feval. Use it almost
14769 everywhere where Feval was used. Look up vars in lexical env.
14771 (Ffunctionp): Move from subr.el.
14772 (Ffuncall): Handle closures.
14773 (apply_lambda): Remove `eval_flags'.
14774 (funcall_lambda): Handle closures and new byte-code-functions.
14775 (Fspecial_variable_p): New function.
14776 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14777 but without exporting it to Lisp.
14779 * doc.c (Fdocumentation, store_function_docstring):
14780 * data.c (Finteractive_form): Handle closures.
14782 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14785 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14787 (exec_byte_code): New function extracted from Fbyte_code to handle new
14788 calling convention for byte-code-functions. Add new byte-codes.
14790 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14792 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14794 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14796 * xdisp.c (redisplay_internal): Fix prototype.
14798 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14800 * xdisp.c (SCROLL_LIMIT): New macro.
14801 (try_scrolling): Use it when setting scroll_limit.
14802 Limit scrolling to 100 screen lines.
14803 (redisplay_window): Even when falling back on "recentering",
14804 position point in the window according to scroll-conservatively,
14805 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14807 (try_scrolling): When point is above the window, allow searching
14808 as far as scroll_max, or one screenful, to compute vertical
14809 distance from PT to the scroll margin position. This prevents
14810 try_scrolling from unnecessarily failing when
14811 scroll-conservatively is set to a value slightly larger than the
14812 window height. Clean up the case of PT below the margin at bottom
14813 of window: scroll_max can no longer be INT_MAX. When aggressive
14814 scrolling is in use, don't let point enter the opposite scroll
14815 margin as result of the scroll.
14816 (syms_of_xdisp) <scroll-conservatively>: Document the
14817 threshold of 100 lines for never-recentering scrolling.
14819 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14821 * dispextern.h (move_it_by_lines):
14822 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14823 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
14824 (message_log_check_duplicate): Remove parameters `prev_bol' and
14825 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14826 (redisplay_internal): Remove parameter `preserve_echo_area',
14827 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14829 * indent.c (Fvertical_motion):
14830 * window.c (window_scroll_pixel_based, Frecenter):
14831 Don't pass `need_y_p' to `move_it_by_lines'.
14833 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14835 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14836 steal a few bits to be more compact.
14837 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14838 Remove unneeded casts.
14840 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14842 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14844 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14845 binding" message (bug#7967).
14847 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14849 Fix more problems found by GCC 4.6.0's static checks.
14851 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14852 Remove unused local var.
14854 * editfns.c (Fmessage_box): Remove unused local var.
14856 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14857 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14858 Omit unused local vars.
14859 * window.c (shrink_windows): Omit unused local var.
14860 * menu.c (digest_single_submenu): Omit unused local var.
14861 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14862 Omit unused local var.
14864 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14865 Don't assume string length fits in int.
14866 (keyremap_step, read_key_sequence): Use size_t for sizes.
14867 (read_key_sequence): Don't check last_real_key_start redundantly.
14869 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14870 instead of alloca (Bug#8344).
14872 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14873 (Fbacktrace_frame): Don't assume nframes fits in int.
14875 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14877 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14880 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14882 * cm.c (calccost): Turn while-do into do-while, for clarity.
14884 * keyboard.c (syms_of_keyboard): Use the same style as later
14885 in this function when indexing through an array. This also
14886 works around GCC bug 48267.
14888 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14890 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

14893 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14895 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14896 This avoids undefined behavior on integer overflow, and is a bit
14897 more convenient anyway since it is compared to a size_t variable.
14899 Variadic C functions now count arguments with size_t, not int.
14900 This avoids an unnecessary limitation on 64-bit machines, which
14901 caused (substring ...) to crash on large vectors (Bug#8344).
14902 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14903 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

14909 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14910 (funcall_lambda, mark_backtrace): Likewise.
14911 * fns.c (concat): Likewise.
14912 * frame.c (x_set_frame_parameters): Likewise.
14913 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14914 0 if not found, not -1. All callers changed.
14916 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14917 (stack_copy_size): Now size_t, not int.
14918 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14920 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14922 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14923 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

14926 * lisp.h (multibyte_char_to_unibyte):
14927 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14928 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14929 * character.h (CHAR_TO_BYTE8):
14930 * cmds.c (internal_self_insert):
14931 * editfns.c (general_insert_function):
14932 * keymap.c (push_key_description):
14933 * search.c (Freplace_match):
14934 * xdisp.c (message_dolog, set_message_1): All callers changed.
14936 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14938 * keyboard.c (safe_run_hook_funcall): New function.
14939 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14940 don't set the hook to nil, but remove the offending function instead.
14941 (Qcommand_hook_internal): Remove, unused.
14942 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14943 Vcommand_hook_internal.
14945 * eval.c (enum run_hooks_condition): Remove.
14946 (funcall_nil, funcall_not): New functions.
14947 (run_hook_with_args): Call each function through a `funcall' argument.
14948 Remove `cond' argument, now redundant.
14949 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14950 (Frun_hook_with_args_until_failure): Adjust accordingly.
14951 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14953 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14955 * dispextern.h (string_buffer_position): Remove declaration.
14957 * print.c (strout): Remove parameter `multibyte', unused since
14958 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14960 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14961 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14962 All callers changed.
14964 * w32.c (_wsa_errlist): Use braces for struct initializers.
14966 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14967 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14968 All callers changed.
14969 (string_buffer_position): Likewise. Also, make static (it's never
14970 used outside xdisp.c).

14974 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14975 All callers changed.
14977 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
14979 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

14990 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
14992 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

15008 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
15010 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
15012 * w32.c (read_unc_volume): Use parameter `henum', instead of
15013 global variable `wget_enum_handle'.
15015 * keymap.c (describe_vector): Remove parameters `indices' and
15016 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

15031 * gtkutil.c (xg_maybe_add_timer):
15032 * keyboard.c (readable_events):
15033 * process.c (wait_reading_process_output):
15034 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
15036 * insdel.c (adjust_markers_gap_motion):
15037 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

15111 2011-03-23 Julien Danjou <julien@danjou.info>
15113 * term.c (Fsuspend_tty, Fresume_tty):
15114 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
15115 * window.c (temp_output_buffer_show):

15121 * cmds.c (internal_self_insert):
15122 * callint.c (Fcall_interactively):
15123 * buffer.c (Fkill_all_local_variables):
15124 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
15126 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
15127 unconditionally since it does the check itself.
15129 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
15131 Fix more problems found by GCC 4.5.2's static checks.
15133 * coding.c (encode_coding_raw_text): Avoid unnecessary test
15134 the first time through the loop, since we know p0 < p1 then.
15135 This also avoids a gcc -Wstrict-overflow warning.
15137 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
15138 leading to a memory leak, possible in functions like
15139 load_charset_map_from_file that can allocate an unbounded number
15140 of objects (Bug#8318).
15142 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
15143 that could (at least in theory) be that large.
15145 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
15146 This is less likely to overflow, and avoids undefined behavior if
15147 overflow does occur. All callers changed. Use strtoul to scan
15148 for the unsigned long integer.
15149 (pint2hrstr): Simplify and tune code slightly.
15150 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

15165 * process.c (Fmake_network_process): Use socklen_t, not int,
15166 where POSIX says socklen_t is required in portable programs.
15167 This fixes a porting bug on hosts like 64-bit HP-UX, where
15168 socklen_t is wider than int (Bug#8277).
15169 (Fmake_network_process, server_accept_connection):
15170 (wait_reading_process_output, read_process_output):
15173 * process.c: Rename or move locals to avoid shadowing.

15180 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
15181 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
15183 Make tparam.h and terminfo.c consistent.
15184 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
15185 Include tparam.h instead, since it declares them.
15186 * cm.h (PC): Remove extern decl; tparam.h now does this.
15187 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
15188 * terminfo.c: Include tparam.h, to check interfaces.
15189 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
15190 (tparam): Adjust signature to match interface in tparam.h;
15191 this removes some undefined behavior. Check that outstring and len
15192 are zero, which they always are with Emacs.
15193 * tparam.h (PC, BC, UP): New extern decls.
15195 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
15196 (xftfont_open): Rename locals to avoid shadowing.
15198 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
15199 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
15200 (OTF_TAG_SYM): Omit macro if not needed.
15201 (ftfont_list): Remove unused local.
15202 (get_adstyle_property, ftfont_pattern_entity):
15203 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
15204 Rename locals to avoid shadowing.
15206 * xfont.c (xfont_list_family): Mark var as initialized.
15208 * xml.c (make_dom): Now static.
15210 * composite.c (composition_compute_stop_pos): Rename local to
15212 (composition_reseat_it): Remove unused locals.
15213 (find_automatic_composition, composition_adjust_point): Likewise.
15214 (composition_update_it): Mark var as initialized.
15215 (find_automatic_composition): Mark vars as initialized,
15216 with a FIXME (Bug#8290).
15218 character.h: Rename locals to avoid shadowing.
15219 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
15220 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
15221 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
15222 (BUF_DEC_POS): Be more systematic about renaming local temporaries
15223 to avoid shadowing.
15225 * textprop.c (property_change_between_p): Remove; unused.
15227 * intervals.c (interval_start_pos): Now static.
15229 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
15231 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
15232 Rename locals to avoid shadowing.
15234 * sound.c (wav_play, au_play, Fplay_sound_internal):
15235 Fix pointer signedness.
15236 (alsa_choose_format): Remove unused local var.
15237 (wav_play): Initialize a variable to 0, to prevent undefined
15238 behavior (Bug#8278).
15240 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
15242 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
15244 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
15245 clobbering (Bug#8298).

15247 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
15249 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
15250 This should get cleaned up, so that child_setup has the
15251 same signature on all platforms.
15253 * callproc.c (call_process_cleanup): Now static.
15254 (relocate_fd): Rename locals to avoid shadowing.
15256 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

15384 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
15385 some of which prompt warnings from gcc -Wbad-function-cast.
15386 (Fformat_time_string, Fencode_time, Finsert_char):

15415 (Fmemory_limit): Cast sbrk's returned value to char *.
15417 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

15420 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
15422 Use functions, not macros, for up- and down-casing (Bug#8254).
15423 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15424 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
15425 to use the following functions instead of these macros.
15426 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
15427 EMACS_INT, since callers assume the returned value fits in int.
15428 (upcase1): Likewise, for UPCASE_TABLE.
15429 (uppercasep, lowercasep, upcase): New static inline functions.
15430 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

15440 (regex_compile, re_match_2_internal): Mark locals as initialized.
15441 (RETALLOC_IF): Define only if needed.
15442 (WORDCHAR_P): Likewise. This one is never needed, but is used
15443 only in a comment talking about a compiler bug, so put inside
15444 the #if 0 of that comment.
15445 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15446 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

15472 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
15473 New macros, so that the caller can use some names other than
15474 gcpro1, gcpro2, etc.
15475 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15477 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15478 argument, for consistency with GCPRO2_VAR, etc: it is now the
15479 prefix of the variable, not the variable itself. All uses
15481 * dired.c (directory_files_internal, file_name_completion):
15482 Rename locals to avoid shadowing.
15484 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15485 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15486 dired.c's scmp function, had undefined behavior.
15487 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15488 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15489 * buffer.h: ... to here, because these macros use current_buffer,
15490 and the new implementation with inline functions needs to have
15491 current_buffer in scope now, rather than later when the macros
15493 (downcase, upcase1): New static inline functions.
15494 (DOWNCASE, UPCASE1): Reimplement using these functions.
15495 This avoids undefined behavior in expressions like
15496 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15497 from race conditions in accessing the global variables
15498 case_temp1 and case_temp2.
15499 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15500 * lisp.h (case_temp1, case_temp2): Remove their decls.
15501 * character.h (ASCII_CHAR_P): Move from here ...
15502 * lisp.h: ... to here, so that the inline functions mentioned
15503 above can use them.
15505 * dired.c (directory_files_internal_unwind): Now static.
15507 * fileio.c (file_name_as_directory, directory_file_name):

15510 (file_name_as_directory): Use const pointers when appropriate.
15511 (Fexpand_file_name): Likewise. In particular, newdir might
15512 point at constant storage, so make it a const pointer.
15513 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
15514 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15516 (Fset_file_times, Finsert_file_contents, auto_save_error):

15521 to avoid shadowing.
15523 * marker.c (bytepos_to_charpos): Remove; unused.
15525 * lisp.h (verify_bytepos, count_markers): New decls,
15526 so that gcc does not warn that these functions aren't declared.
15528 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15529 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15530 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15531 (copy_text): Remove unused local var.
15533 * filelock.c (within_one_second): Now static.
15534 (lock_file_1): Rename local to avoid shadowing.
15536 * buffer.c (fix_overlays_before): Mark locals as initialized.
15537 (fix_start_end_in_overlays): Likewise. This function should be
15538 simplified by using pointers-to-pointers, but that's a different
15540 (switch_to_buffer_1): Now static.
15541 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15542 (report_overlay_modification): Rename locals to avoid shadowing.
15544 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
15545 Fix pointer signedness issue.
15546 (sys_subshell): Mark local as volatile if checking for lint,
15547 to suppress a gcc -Wclobbered warning that does not seem to be right.
15548 (MAXPATHLEN): Define only if needed.
15550 * process.c (serial_open, serial_configure): Move decls from here ...
15551 * systty.h: ... to here, so that they can be checked.
15553 * fns.c (get_random, seed_random): Move extern decls from here ...
15554 * lisp.h: ... to here, so that they can be checked.
15556 * sysdep.c (reset_io): Now static.
15557 (wait_for_termination_signal): Remove; unused.
15559 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

15562 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
15563 (DENSE_TABLE_SIZE): Remove; unused.
15564 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
15565 (describe_map_tree):
15566 Rename locals to avoid shadowing.
15568 * keyboard.c: Declare functions static if they are not used elsewhere.
