1 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
4 as that's faster and simpler than static storage. Don't bother
5 with the g_main_context_query overhead if g_main_context_pending
6 says no events are pending.
7 (gfds, gfds_size): Remove these static vars.
8 (xgselect_initialize): Remove; no longer needed.
9 All uses and decls removed.
11 * emacs.c (fatal_error_signal_hook): Remove.
12 All uses removed. This leftover from old code was always 0.
14 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
15 * casefiddle.c (casify_object, casify_region):
16 * casetab.c (set_case_table):
17 * category.c, category.h (word_boundary_p):
18 * category.h (CHAR_HAS_CATEGORY):
19 Use bool for booleans, instead of int.
21 2012-08-25 Eli Zaretskii <eliz@gnu.org>
23 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
25 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
27 On assertion failure, print backtrace if available.
28 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
29 (die) [ENABLE_CHECKING]: Print a backtrace if available.
30 * Makefile.in (LIB_EXECINFO): New macro.
33 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
34 * bytecode.c (exec_byte_code):
35 * callint.c (check_mark, Fcall_interactively):
36 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
37 (getenv_internal, sync_process_alive, call_process_exited):
38 * lisp.h (USE_SAFE_ALLOCA):
39 Use bool for booleans, instead of int.
40 * lisp.h, process.h: Adjust prototypes to match above changes.
41 * callint.c (Fcall_interactively): Don't assume the mark's
44 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
46 * buffer.c, buffer.h: Use bool for boolean.
47 * buffer.c (reset_buffer_local_variables)
48 (buffer_lisp_local_variables, Fset_buffer_modified_p)
49 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
50 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
51 (overlay_touches_p, overlay_strings, Foverlay_put)
52 (report_overlay_modification, call_overlay_mod_hooks):
53 (mmap_enlarge, mmap_set_vars):
54 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
55 Use bool for booleans, instead of int.
56 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
57 since the 1-or-0 return value is always ignored anyway.
59 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
60 * buffer.h, lisp.h: Adjust prototypes to match above changes.
62 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
64 * bidi.c: Use bool for boolean.
65 This is a bit more readable, and makes the text segment of bidi.o
66 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
67 Presumably it's faster too.
68 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
70 (bidi_cache_find_level_change, bidi_cache_iterator_state)
71 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
72 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
73 (bidi_explicit_dir_char, bidi_level_of_next_char)
74 (bidi_find_other_level_edge, bidi_move_to_visually_next):
75 Use bool for booleans, instead of int.
76 * dispextern.h (bidi_init_it, bidi_paragraph_init)
77 (bidi_unshelve_cache): Adjust decls to match code.
79 2012-08-23 Martin Rudalics <rudalics@gmx.at>
81 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
84 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
86 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
87 * atimer.h: Include <stdbool.h>.
89 2012-08-22 Dan Nicolaescu <dann@gnu.org>
91 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
92 compile time tests instead of run time tests on systems that do
94 (FRAME_MAC_P): Remove leftover from deleted code.
95 * frame.c (syms_of_frame): Remove leftover from deleted code.
97 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
99 * nsterm.m (insertText:): Don't clear modifiers if code is space.
101 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
103 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
104 Otherwise, the compiler complains about (A?B:C) where B is void
105 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
106 (fontset_add): Return void, for FONTSET_ADD.
108 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
110 * alloc.c: Use bool for booleans.
111 (gc_in_progress, abort_on_gc)
112 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
113 (dont_register_blocks) [GC_MALLOC_CHECK]:
114 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
115 (check_string_bytes, make_specified_string, memory_full)
116 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
117 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
118 (mark_stack, valid_pointer_p, make_pure_string)
119 (Fgarbage_collect, survives_gc_p, gc_sweep):
120 Use bool for booleans, instead of int.
121 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
123 * alloc.c (PURE_POINTER_P):
124 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
125 * editfns.c (Fformat):
126 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
128 * fns.c (sweep_weak_table):
129 * lisp.h (suppress_checking, push_message, survives_gc_p)
130 (make_pure_string, gc_in_progress, abort_on_gc):
131 * lread.c (readchar, read1):
132 * print.c (Fprin1_to_string):
133 * xdisp.c (push_message):
134 Use bool for booleans affected directly or indirectly by
137 Make recently-introduced setters macros.
138 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
139 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
140 (set_fontset_default, set_fontset_fallback): Rename from their
141 upper-case counterparts, and make them functions rather than macros.
142 This is more consistent with the other recently-introduced setters.
143 These don't need to be inline, since they're local.
145 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
147 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
148 the loop (Bug#12247).
150 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
152 * lisp.h (vcopy): Use memcpy rather than our own loop.
153 This fixes a performance regression introduced by the recent
154 addition of vcopy. This means 'vcopy' will need to be modified
155 for a copying collector, but that's OK. Also, tighten the
156 checking in the assertion.
158 2012-08-21 Eli Zaretskii <eliz@gnu.org>
160 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
161 components for RTL text (Bug#11860). Adjust X-OFFSET of each
162 non-base glyph for the width of the base character, according to
163 what x_draw_composite_glyph_string_foreground expects. Generate
164 WADJUST value according to composition_gstring_width's
165 expectations, to produce correct width of the composed character.
166 Reverse the sign of the DU offset produced by ScriptPlace.
168 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
170 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
172 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
174 Avoid direct writes to contents member of struct Lisp_Vector.
175 * lisp.h (vcopy): New function to copy data into vector.
176 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
177 * fns.c (Ffillarray): Use ASET.
178 * keyboard.c (timer_check_2): Use AREF and ASET.
179 (append_tool_bar_item, Frecent_keys): Use vcopy.
180 * lread.c (read_vector): Use ASET.
181 * msdos.c (Frecent_doskeys): Use vcopy.
182 * xface.c (Finternal_copy_lisp_face): Use vcopy.
183 (Finternal_merge_in_global_face): Use ASET and vcopy.
184 * xfont.c (xfont_list_pattern): Likewise.
186 2012-08-21 Martin Rudalics <rudalics@gmx.at>
188 * window.c (Fwindow_point): For the selected window always return
189 the position of its buffer's point.
190 (Fset_window_point): For the selected window always go in its
191 buffer to the specified position.
193 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
195 Setter macros for fontsets.
196 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
197 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
198 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
201 2012-08-20 Glenn Morris <rgm@gnu.org>
203 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
204 Don't assume that `ln -f' works.
206 2012-08-20 Eli Zaretskii <eliz@gnu.org>
208 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
209 and later about non-assignments with no effect. See discussion at
210 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
213 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
215 Inline setter functions for Lisp_Objects slots of struct specbinding.
216 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
219 2012-08-20 Martin Rudalics <rudalics@gmx.at>
221 * window.c (select_window): Always make selected window's buffer
224 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
226 Use AREF and ASET for docstrings of category tables.
227 * category.h (CATEGORY_DOCSTRING): Use AREF.
228 (SET_CATEGORY_DOCSTRING): Use ASET.
229 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
231 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
233 Inline setter functions for hash table members.
234 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
235 (set_hash_hash, set_hash_index): Rename with _slot suffix.
236 (set_hash_key_and_value, set_hash_index, set_hash_next)
237 (set_hash_hash): New functions.
238 * charset.c, fns.c: Adjust users.
240 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
242 Inline getter and setter functions for per-buffer values.
243 * buffer.h (per_buffer_default, set_per_buffer_default)
244 (per_buffer_value, set_per_buffer_value): New functions.
245 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
246 * buffer.c, data.c: Adjust users.
248 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
250 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
252 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
254 Rely on <config.h> + <unistd.h> to declare 'environ',
255 as gnulib does this if the system doesn't.
256 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
257 Remove declaration. MS-Windows declares it on stdlib.h which is
258 included by conf_post.h.
259 * emacs.c (environ) [DOUG_LEA_MALLOC]:
260 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
261 * vm-limit.c: Include <unistd.h>, for 'environ'.
263 * unexaix.c, unexcoff.c: Include "mem-limits.h".
264 (start_of_data): Remove decl; mem-limits.h provides it.
266 * xdisp.c (handle_invisible_prop): Make it a bit faster
267 and avoid a gcc -Wmaybe-uninitialized diagnostic.
269 2012-08-19 Chong Yidong <cyd@gnu.org>
271 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
274 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
276 * .gdbinit: Use call instead of set when calling a function in the
279 * data.c (set_internal): Don't use set_blv_found.
280 (Fkill_local_variable): Likewise.
282 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
284 * nsfont.m (ns_ascii_average_width): Ensure the string
285 ascii_printable is initialized with a null-terminated character
286 array. Otherwise, it can contain undesired extra characters.
288 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
290 port new setting code to Sun C 5.8 2005/10/13
291 * chartab.c, lisp.h (char_table_set, char_table_set_range):
292 Return void, not Lisp_Object. Otherwise, the compiler
293 complains about (A?B:C) where B is void and C is Lisp_Object
294 when compiling CHAR_TABLE_SET, due to the recent change to
295 the API of sub_char_table_set_contents.
297 2012-08-18 Chong Yidong <cyd@gnu.org>
299 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

1127 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
1128 * w32.c (init_environment): Change the default values of many
1129 environment variables in dflt_envvars[] to NULL, to avoid pushing
1130 them into environment when they were not already defined.
1131 Remove the code that deletes site-lisp subdirectories from the default
1132 value of EMACSLOADPATH, as it is no longer needed.
1133 (check_windows_init_file): Now external, not static.
1134 Use Vload_path as is, without adding anything, as this function is now
1135 called when Vload_path is already set up.
1137 * w32.h (check_windows_init_file): Add prototype.
1139 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

1145 any, in the DEFALT argument into the root of the Emacs build or
1146 installation tree, as appropriate.
1148 * callproc.c (init_callproc_1): Call decode_env_path instead of
1149 doing its equivalent by hand.

1167 Remove unnecessary casts involving pointers.
1168 These casts are no longer needed now that we assume C89 or later,

1182 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
1183 Remove unnecessary pointer casts.
1184 * alloc.c (record_xmalloc): New function.
1185 * lisp.h (record_xmalloc): New decl.
1186 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
1187 more like a function. This is because the pointer cast is not
1188 needed. All uses changed.
1189 * print.c (print_string, print_error_message): Avoid length recalc.
1191 Improve fix for macroexp crash with debugging (Bug#12118).
1192 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
1193 ARRAY_MARK_FLAG when checking subscripts, because ASET is
1194 not supposed to be invoked from the garbage collector.
1195 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
1196 (gc_aset): New function, which is like ASET but can be
1197 used in the garbage collector.

1213 headers (most versions of MinGW w32api don't).
1214 (get_security_info, create_symbolic_link)
1215 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

1222 have the required privileges.
1223 (get_file_security_desc_by_name): Rename from
1224 get_file_security_desc.

1226 with addition of handling of symlinks and support for 'lstat'.
1227 If possible, get file's attributes and security information by
1228 handle, not by name. Produce S_IFLNK bit for symlinks, when
1229 called from 'lstat'.
1230 (stat, lstat): New functions, call 'stat_worker'.
1231 (symlink, readlink, careadlinkat): Rewritten to create and resolve
1232 symlinks when the underlying filesystem supports them.
1234 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
1236 Fix macroexp crash on Windows with debugging (Bug#12118).
1237 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
1238 checking subscripts; problem introduced with the recent
1239 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
1240 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
1241 since it's used in non-static inline functions now.
1243 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
1244 Don't assume buffer size fits in 'int'. Remove unused local.

1262 * character.c (CHARACTER_INLINE):
1263 * charset.c (CHARSET_INLINE):
1264 * composite.c (COMPOSITE_INLINE):
1265 * dispnew.c (DISPEXTERN_INLINE):
1266 * sysdep.c (SYSTIME_INLINE):
1267 Define to EXTERN_INLINE, so that the corresponding functions
1268 are compiled into code.
1269 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
1270 (INLINE_HEADER_END): New macros.
1271 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

1291 hard-coding the path separator.
1293 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
1295 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
1296 This how ASET and AREF are supposed to work, and makes
1297 it easier to think about future improvements. See
1298 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
1299 * charset.h (set_charset_attr): New function.

1791 the fix for 12036 would have avoided some of the problems noted in

1814 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1815 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1816 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1817 Adjust to changes in lisp.h and emacs.c, by using
1818 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1819 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1820 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1821 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1822 instead of gdb_valbits.
1823 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use

1827 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1828 (xreload, hook-run, hookpost-run): Remove.
1829 * emacs.c: Include <verify.h>.
1830 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

1843 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1844 more convenient now. All uses changed.
1845 (VALMASK) [USE_LSB_TAG]: Also define in this case.

1861 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1862 than macros. This simplifies debugging in the usual case, since
1863 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1864 and it allows expressions involving EMACS_INT casts.
1865 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1867 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

1884 buffer_defaults and buffer_local_symbols (for sanity and safety).
1886 2012-07-24 Eli Zaretskii <eliz@gnu.org>

1919 Swap buffer text indirection counters in Fbuffer_swap_text.
1920 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1921 This avoids crash reported by Christoph Scholtes at
1922 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1924 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1926 * nsmenu.m (Popdown_data): New struct.

1951 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
1952 as it's limited by the amount of memory, not by INT_MAX.

2730 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2731 * nsterm.m (ns_term_init):
2732 Avoid the need for strncpy, by using build_string or
2733 make_unibyte_string directly. Use dtoastr, not snprintf.
2734 * process.c (Fmake_network_process): Diagnose service names that
2735 are too long, rather than silently truncating them or creating
2736 non-null-terminated names.
2737 (Fnetwork_interface_info): Likewise, for interface names.
2738 * sysdep.c (system_process_attributes) [GNU_LINUX]:
2739 Prefer sprintf to strncat.
2740 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

2746 Clarify fallback case.
2748 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

2752 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
2753 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

2766 Optimize pure C strings initialization.
2767 * lisp.h (make_pure_string): Fix prototype.
2768 (build_pure_c_string): New function, defined as static inline. This
2769 provides a better opportunity to optimize away calls to strlen when
2770 the function is called with compile-time constant argument.
2771 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2772 argument, adjust users accordingly. Use build_pure_c_string where
2774 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2775 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2776 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2778 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2780 Avoid calls to strlen in miscellaneous functions.
2781 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2782 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
2783 * lread.c (openp): Likewise.

2787 Avoid calls to strlen in path processing functions.
2788 * fileio.c (file_name_as_directory): Add comment. Change to add
2789 srclen argument and return the length of result. Adjust users

2793 Adjust users accordingly.
2794 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2796 2012-07-10 Glenn Morris <rgm@gnu.org>
2798 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

2803 * s/gnu.h (DATA_START): Move definitions to configure.
2805 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2806 We include usg5-4-common.h, which defines them both.
2808 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2809 O_RDONLY already includes it).
2811 Stop ns builds setting the EMACSLOADPATH environment variable.
2812 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2813 Now it does not set EMACSLOADPATH, just returns the load-path string.
2814 * nsterm.h: Update accordingly.
2815 * lread.c [HAVE_NS]: Include nsterm.h.
2816 (init_lread) [HAVE_NS]: Use ns_load_path.

2819 2012-07-09 Glenn Morris <rgm@gnu.org>
2821 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2822 since the included bsd-common.h does so.
2824 Stop ns builds setting the EMACSPATH environment variable.
2825 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2826 (ns_init_paths): Do not set EMACSPATH.
2827 * nsterm.h (ns_exec_path): Add it.
2828 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2831 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2833 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2835 * process.c (wait_reading_process_output): 'waitchannels' was unset
2836 when read_kbd || !NILP (wait_for_cell); fix this.
2838 Add GCC-style 'const' attribute to functions that can use it.
2839 * character.h (char_resolve_modifier_mask):
2840 * keyboard.h (make_ctrl_char):
2841 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

2850 Add decls with ATTRIBUTE_CONST.
2852 Minor improvements to make_formatted_string.
2853 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2854 where int is good enough, as vsprintf returns an int.
2855 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2857 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2859 Use make_formatted_string to avoid double length calculation.
2860 * lisp.h (make_formatted_string): New prototype.

2884 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2886 Move marker debugging code under MARKER_DEBUG.
2887 * marker.c (MARKER_DEBUG): Move marker debugging code under
2888 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2889 for bootstrap with --enable-checking (~3x slowdown reported
2890 by Juanma Barranquero <lekktu@gmail.com>).
2891 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2893 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2895 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2896 See <http://bugs.gnu.org/11825#29>.
2898 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2900 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2901 has no font, use the frame's font. (Bug#11813)
2902 (display_line): Add commentary about displaying truncation glyphs
2904 (produce_special_glyphs): Move here from term.c.
2906 * term.c (produce_special_glyphs): Move to xdisp.c.
2908 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2911 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2913 * xdisp.c (display_line): Avoid warning about implicit declaration
2916 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2918 * lisp.h: Remove empty conditional.
2920 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2922 * lread.c (load_path_check): Now static.
2924 Fix some minor --with-ns problems found by static checking.
2925 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2926 (x_set_font) [!HAVE_X_WINDOWS]:
2927 * image.c (xpm_load_image) [HAVE_NS]:
2928 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2929 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2930 Remove unused local.
2931 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2932 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2933 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2934 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2935 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2936 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2937 Fix pointer signedness problem.
2938 * xfaces.c (FRAME_X_FONT_TABLE):
2939 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2941 2012-07-07 Glenn Morris <rgm@gnu.org>
2943 * lread.c (load_path_check): New function, split from init_lread.
2944 (init_lread): Reorganize. Motivation:
2945 If EMACSLOADPATH is set, check/warn about that rather than the
2946 defaults, which we are not going to use. Hence we can remove
2947 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2948 Don't warn if site-lisp directories are missing.
2949 If not installed, start from a blank load-path, since
2950 PATH_LOADSEARCH refers to the eventual installation directories.
2952 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2954 Support truncation and continuation glyphs on GUI frames, when
2955 fringes are disabled. (Bug#11832)
2956 * xdisp.c (init_iterator): Get dimensions of truncation and
2957 continuation glyphs even if on GUI frames.
2958 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2959 or both, are absent.
2960 (start_display, move_it_in_display_line_to): Handle the case of a
2961 GUI frame without a fringe to display continuation or truncation
2963 (insert_left_trunc_glyphs): Support GUI frames: make sure
2964 truncation glyphs overwrite enough glyphs from the current line to
2965 have sufficient space in pixels.
2966 (display_line): Support truncation and continuation glyphs on GUI
2967 frames. If some spare pixels are left on the line after inserting
2968 the truncation glyphs, fill that space with a stretch glyph of a
2969 suitably computed width.
2971 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2972 produce_glyphs, to support GUI sessions.
2974 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2976 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2978 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2980 Do not require float-time's arg to fit in time_t (Bug#11825).
2981 This works better on hosts where time_t is unsigned, and where
2982 float-time is applied to the (negative) difference between two times.
2983 * editfns.c (decode_time_components): Last arg is now double *,
2984 not int *, and means to store all the result as a double, without
2985 worrying about whether the seconds part fits in time_t.
2986 All callers changed.
2987 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2988 All callers changed.
2989 (Ffloat_time): Do not fail merely because the specified time falls
2990 outside of time_t range.
2992 2012-07-07 Glenn Morris <rgm@gnu.org>
2994 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
2995 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
2996 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
2998 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
3000 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
3001 Update dependencies.
3003 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
3005 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3007 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

3009 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
3010 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
3011 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
3012 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
3014 * xfont.c (compare_font_names): Redo to omit the need for casts.
3016 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
3018 * xfns.c (Fx_change_window_property): Doc fix.
3019 * w32fns.c (Fx_change_window_property): Doc fix.
3021 * w32fns.c (Fx_window_property): Accept the same arguments as the
3022 X Windows version. Doc fix.
3023 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
3025 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
3026 Eli Zaretskii <eliz@gnu.org>
3028 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
3029 Windows-specific code from nt/config.nt moved here.
3030 Obsolete settings removed.
3032 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3034 * process.c: Avoid unnecessary calls to gettime.
3035 (wait_reading_process_output): Don't get the time of day
3036 when gobbling data immediately and not waiting, as there's no need
3037 for it in that case. This removes a FIXME.
3039 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
3041 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
3042 is defined (Bug#11768).
3044 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3046 Fix marker debugging code.
3047 * marker.c (byte_char_debug_check): Do not perform the check
3048 if buffer is not multibyte.
3049 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3050 Call byte_char_debug_check with correct arguments.
3052 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3054 Compile marker debugging code only if ENABLE_CHECKING is defined.
3055 * marker.c (byte_char_debug_check, count_markers):
3056 Use only if ENABLE_CHECKING is defined.
3057 (byte_debug_flag): Remove.
3058 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3059 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
3061 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3063 Avoid code repetition in marker-related functions.
3064 * marker.c (attach_marker): New function.
3065 (Fset_marker, set_marker_restricted, set_marker_both)
3066 (set_marker_restricted_both): Use it.
3067 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
3068 Consistently rename charno to charpos.
3069 (marker_position): Add eassert.
3070 (marker_byte_position): Convert to eassert.

3088 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
3089 * window.c (save_window_save): Likewise.
3091 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3093 Do not use Fdelete_overlay in delete_all_overlays
3094 to avoid redundant calls to unchain_overlay.
3095 * buffer.c (drop_overlay): New function.
3096 (delete_all_overlays, Fdelete_overlay): Use it.
3097 * minibuf.c (get_minibuffer): Fix comment.
3099 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3101 Port to OpenBSD 5.1 amd64.
3102 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
3103 This is needed for OpenBSD, and should be harmless on all BSD systems.
3104 Also, include <sys/sysctl.h>, as it should be available on all
3105 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
3106 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
3107 use p_pid member, not kp_proc.pid.
3109 2012-07-06 Glenn Morris <rgm@gnu.org>
3111 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
3113 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
3115 More xmalloc and related cleanup.
3116 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
3117 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
3118 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
3119 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
3120 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
3121 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
3122 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
3123 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
3124 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
3126 Omit needless casts involving void * pointers and allocation.
3127 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
3128 as the former is more robust if P's type is changed.
3129 Prefer xzalloc to xmalloc + memset 0.
3130 Simplify malloc-or-realloc to realloc.
3131 Don't worry about xmalloc returning a null pointer.
3132 Prefer xstrdup to xmalloc + strcpy.
3133 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
3135 * keyboard.c (apply_modifiers_uncached): Prefer local array to
3136 alloca of a constant.
3138 2012-07-05 Eli Zaretskii <eliz@gnu.org>
3140 * xdisp.c (display_line): Fix horizontal pixel coordinates when
3141 hscroll is larger than the line width. Fixes long and futile
3142 looping inside extend_face_to_end_of_line (on a TTY) producing
3143 glyphs that are not needed and thrown away.

3157 not defined (Bug#11768).
3158 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
3159 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
3160 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
3161 followed by gtk_box_set_homogeneous (Bug#11768).
3162 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
3163 (update_theme_scrollbar_width, xg_create_scroll_bar):
3164 Use gtk_scrollbar_new (Bug#11768).
3165 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

3173 * xdisp.c (window_hscroll_limited): New function.
3174 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
3175 coordinates when window's hscroll is set to insanely large
3178 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
3180 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
3181 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
3183 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
3186 * lisp.h (xzalloc): New prototype. Omit needless casts.
3187 * alloc.c (xzalloc): New function. Omit needless casts.

3189 xmalloc with following memset to xzalloc.

3241 * fileio.c (time_error_value): Check the right error number.
3242 Problem reported by Troels Nielsen in
3243 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
3245 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3247 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
3248 This should be fixed in a better way; see Eli Zaretskii in
3249 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
3250 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
3252 * fileio.c (time_error_value): Rename from special_mtime.
3253 The old name's problems were noted by Eli Zaretskii in
3254 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
3256 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
3257 This variable's comment says Emacs needs at least one GDB-visible
3258 symbol of type enum pvec_type, to work around GDB problems.
3259 The symbol's value doesn't matter.
3261 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
3262 that causes compilation to fail on pre-C99 compilers.
3264 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
3266 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
3267 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
3269 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3271 * buffer.c (init_buffer_once): Fix initialization of
3272 headers for buffer_defaults and buffer_local_symbols.
3273 Reported by Juanma Barranquero <lekktu@gmail.com>.
3275 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
3277 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
3278 * lisp.h (enum pvec_type): Use fewer bits.
3279 (PSEUDOVECTOR_SIZE_BITS): New constant.
3280 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
3281 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
3282 change in pvec_type.
3283 (PSEUDOVECTOR_TYPEP): New macro.
3284 (TYPED_PSEUDOVECTORP): Use it.
3285 * fns.c (internal_equal): Adapt code to extract pvectype.
3286 * emacs.c (gdb_pvec_type): Update type.
3287 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
3288 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
3289 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
3290 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
3291 (sweep_vectors): Use it. Use local var `total_bytes' instead of
3292 abusing vector->header.next.nbytes.
3293 (live_vector_p): Use PVEC_TYPE.
3294 (mark_object): Adapt code to extract pvectype. Use switch.
3296 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3298 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
3299 Tighten new eassert a bit.
3301 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3303 Fix compilation with --enable-gcc-warnings and -O1
3305 * doprnt.c (doprnt): Change type of tem to int, initialize
3306 to avoid compiler warning. Add eassert.
3307 * search.c (simple_search): Initialize match_byte to avoid
3308 compiler warning. Add eassert.
3310 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3312 Avoid weird behavior with large horizontal scrolls.
3313 Without this change, for example, large hscroll values would
3314 mess up Emacs's display on Fedora 15 x86, presumably due to
3315 overflows in int calculations in the display code.
3316 Also, if buffers had long lines, Emacs would freeze.
3317 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
3318 (set_window_hscroll): New function, containing the old guts of
3319 Fset_window_hscroll. Return the clipped value.
3320 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
3321 This avoids the need to check against PTRDIFF_MAX.
3323 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
3325 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3327 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
3329 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3331 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
3332 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
3333 since GCC 4.4.6 issues a bogus warning for them.
3335 Fix bugs in file timestamp newness comparisons.
3336 * fileio.c (Ffile_newer_than_file_p):
3337 * lread.c (Fload): Use full timestamp resolution of files,
3338 not just the 1-second resolution, so that files that are only
3339 slightly newer still count as newer.
3340 * fileio.c (Ffile_newer_than_file_p): Don't assume file
3341 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
3343 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
3345 * fileio.c: Improve handling of file time marker. (Bug#11852)
3346 (special_mtime): New function.
3347 (Finsert_file_contents, Fverify_visited_file_modtime):
3348 Use it to set special mtime values consistently.
3350 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
3352 * fileio.c (Finsert_file_contents): Properly handle st_mtime
3353 marker for non-existing file. (Bug#11852)
3355 2012-07-03 Glenn Morris <rgm@gnu.org>
3357 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
3358 and did not make it into globals.h).
3360 2012-07-03 Tom Tromey <tromey@redhat.com>
3362 * window.c (Fset_window_margins, Fset_window_fringes)
3363 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
3364 * textprop.c (Fprevious_property_change): No longer static.
3365 * syntax.c (Fsyntax_table_p): No longer static.

3387 * intervals.h: Remove EXFUNs.
3388 * fontset.h: Remove EXFUN.

3393 * w32term.h: Remove EXFUNs.
3394 * window.h: Remove EXFUNs.

3396 * xterm.h: Remove EXFUN.
3398 2012-07-03 Glenn Morris <rgm@gnu.org>
3400 * lisp.h (Frandom): Make it visible to C.
3401 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
3402 buffer for invisible buffers. (Bug#1229)
3404 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3406 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
3407 values which aren't power of 2.
3408 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
3409 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
3412 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
3414 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
3416 * alloc.c (mark_object): Revert part of last patch to use `switch'.
3418 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3420 * alloc.c (allocate_vector_block): Remove redundant
3421 calls to mallopt if DOUG_LEA_MALLOC is defined.
3422 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
3423 avoid calls to mallopt if zero_vector is returned.
3425 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3427 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
3428 is enabled, avoid dereferencing NULL current_sblock if
3431 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3433 Cleanup basic buffer management.
3434 * buffer.h (struct buffer): Change layout to use generic vector
3435 marking code. Fix some comments. Change type of 'clip_changed'
3436 to bitfield. Remove unused #ifndef old.
3437 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
3438 (GET_OVERLAYS_AT): Fix indentation.
3439 (for_each_per_buffer_object_at): New macro.

3443 * alloc.c (allocate_buffer): Adjust to match new layout of
3444 struct buffer. Fix comment.
3445 (mark_overlay): New function.

3447 Lisp area of struct buffer.
3448 (mark_object): Use it. Adjust marking of misc objects
3449 and related comments.
3451 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
3453 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
3454 wrapper that is not needed because the wrapped code is a no-op (zero
3455 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
3456 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
3458 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
3460 * alloc.c (mark_buffer): Simplify. Remove prototype.
3461 (mark_object): Add comment. Reorganize marking of vector-like
3462 objects. Use CHECK_LIVE for all vector-like objects except buffers
3463 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
3464 Avoid redundant calls to mark_vectorlike for bool vectors.
3466 2012-06-30 Glenn Morris <rgm@gnu.org>
3468 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3470 * epaths.in (PATH_SITELOADSEARCH): New.
3471 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3472 This is rather than relying on --enable-locallisppath elements
3473 having "site-lisp" in their names. (Bug#10208#25, 11658)
3475 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3477 * w32proc.c (sys_select): Accept and ignore one more argument.
3479 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3481 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3482 (pselect) [!MS_DOS]: Redirect to sys_select.
3484 * sysdep.c: Don't include dos.h and dosfns.h.
3486 * process.c (sys_select):
3487 * msdos.c (sys_select): Accept one more argument and ignore it.
3489 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3490 adapt data types and code to that.
3493 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3494 which clashes with the gnulib function of the same name.
3496 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3498 * font.c (font_style_to_value, font_style_symbolic)
3499 (font_prop_validate_style): Add type checks for values in
3502 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3504 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3507 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3509 * xdisp.c (try_window_id): Undo last change.
3511 * w32.c (getwd): Adjust commentary about startup_dir.
3512 (init_environment): Always call sys_access, even in non-MSVC
3513 builds. Don't chdir to the directory of the Emacs executable.
3514 This undoes code from 1997 which was justified by the need to
3515 "avoid conflicts when removing and renaming directories". But its
3516 downside was that every relative file name was being interpreted
3517 relative to the directory of the Emacs executable, which can never
3518 be TRT. In particular, it broke sys_access when called with
3519 relative file names.
3520 (sys_access): Map GetLastError to errno.
3522 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3524 * window.h (struct window): Change type of 'fringes_outside_margins'

3528 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3531 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3533 * gnutls.c (emacs_gnutls_handshake):
3534 Add QUIT to make the loop interruptible.
3536 2012-06-29 Glenn Morris <rgm@gnu.org>
3538 * charset.c (init_charset): Make lack of etc/charsets fatal.
3540 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3542 * editfns.c (region_limit): Fix type mismatch.
3544 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3546 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3547 undefined. Convert from xassert to eassert.
3548 * nsmenu.m: Convert from xassert to eassert.
3549 * nsterm.m: Likewise.
3551 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3553 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3555 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3557 Avoid integer overflow on scroll-left and scroll-right.
3558 * window.c (HSCROLL_MAX): New macro.
3559 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3560 overflow when requested scroll falls outside ptrdiff_t range.
3562 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3564 * window.h (struct window): Change type of 'hscroll',
3565 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3566 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3567 Adjust users accordingly.
3568 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3569 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3570 from EMACS_INT to ptrdiff_t.
3571 (make_window): Omit redundant initialization.
3573 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

3577 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3579 * window.h (struct window): Change type of 'use_time' and
3580 'sequence_number' from Lisp_Object to int.

3589 enabled with --enable-checking=[all,glyphs] configure option.
3590 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3591 adjust comments accordingly.

3709 * w32proc.c (sys_spawnve): Likewise.
3710 * xterm.c (x_term_init): Likewise.
3712 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3714 Use sprintf return value instead of invoking strlen on result.
3715 In the old days this wasn't portable, since some sprintf
3716 implementations returned char *. But they died out years ago and
3717 Emacs already assumes sprintf returns int.
3718 Similarly for float_to_string.
3719 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
3720 * ccl.c (ccl_driver):
3721 * character.c (string_escape_byte8):

3724 * print.c (print_object):
3725 * xdisp.c (message_dolog):
3726 * xfns.c (syms_of_xfns):
3727 Use sprintf or float_to_string result to avoid need to call strlen.
3728 * data.c (Fnumber_to_string):
3729 Use make_unibyte_string, since the string must be ASCII.
3730 * lisp.h, print.c (float_to_string): Now returns int length.
3731 * term.c (produce_glyphless_glyph):
3732 Use sprintf result rather than recomputing it.
3734 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3735 * Makefile.in (ALL_CFLAGS):
3736 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
3737 * gmalloc.c, regex.c: Include <config.h> unconditionally.

3741 * dispextern.h (xstrcasecmp): Define to library function
3742 strcasecmp if available.
3743 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

3758 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
3760 * gtkutil.c (get_utf8_string): Remove redundant assignment.
3761 sprintf already null-terminates its output.
3763 * xfns.c (x_window): Remove redundant cast.
3765 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3767 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
3768 `const char *' to `char *' to avoid compiler warning.
3770 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3772 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
3773 instead of truncating it to 63 (admittedly a generous limit).
3775 * process.c: Fix spelling and caps in comments.
3777 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
3779 * emacs.c (setpgrp): Remove definition, unused.

3826 Remove unnecessary forward decls.
3828 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3830 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
3831 * lisp.h (WAIT_READING_MAX): New macro.
3832 * dispnew.c (Fsleep_for, sit_for):
3833 * keyboard.c (kbd_buffer_get_event):
3834 * process.c (Faccept_process_output):
3835 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3836 This improves on the previous patch, which introduced a bug
3837 when time_t is unsigned and as wide as intmax_t.
3838 See <http://bugs.gnu.org/9000#51>.
3840 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3842 * dispnew.c (sit_for, Fsleep_for):
3843 * keyboard.c (kbd_buffer_get_event):

3856 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
3857 Privately reported by Herbert J. Skuhra.
3858 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
3860 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
3861 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3863 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3865 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
3866 last argument of make_unibyte_string.
3868 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
3869 language ID in the event parameters.
3871 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3872 event.code, not the obscure "character set ID".
3874 2012-06-23 Chong Yidong <cyd@gnu.org>
3876 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
3878 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3880 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

3895 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
3896 Privately reported by Herbert J. Skuhra.
3897 [__FreeBSD__]: Remove "*/" typo after "#include".

3901 Don't assume EMACS_TIME and struct timeval are the same type.
3903 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3905 Support higher-resolution time stamps (Bug#9000).
3906 The time stamps are only nanosecond-resolution at the C level,
3907 since that's the best that any real-world system supports now.
3908 But they are picosecond-resolution at the Lisp level, as that's
3909 easy, and leaves room for future OS improvements.
3911 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3914 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3915 Don't get current time unless it's needed.
3917 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3918 now provides it if it's absent.
3919 (start_atimer): Port to higher-res time stamps.
3920 Check for time stamp overflow. Don't get current time more
3921 often than is needed.
3923 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3924 Include systime.h, not time.h.
3925 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3927 * dired.c: Include stat-time.h.
3928 (Ffile-attributes): File times now have higher resolution.
3930 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3931 (struct image): Timestamp now has higher resolution.
3933 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3934 has at least microseconds now. All uses removed.
3935 (update_frame, update_single_window, update_window, update_frame_1)
3936 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3937 (duration_to_sec_usec): Remove; no longer needed.
3939 * editfns.c (time_overflow): Now extern.
3940 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3941 (float-time, Fformat_time_string, Fcurrent_time_string)
3942 (Fcurrent_time_zone): Accept and generate higher-resolution
3944 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3945 (decode_time_components, lisp_seconds_argument): New functions.
3946 (make_time): Now static.
3947 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3948 Report an error if the time is invalid, rather than having the caller
3951 * fileio.c: Include <stat-time.h>
3952 (Fcopy_file): Copy higher-resolution time stamps.
3953 Prefer to set the time stamp via a file descriptor if that works.
3954 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3955 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3956 (Fvisited_file_modtime, Fset_visited_file_modtime):
3957 Support higher-resolution time stamps.
3959 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3961 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3963 * image.c (prepare_image_for_display, clear_image_cache)
3964 (lookup_image): Port to higer-resolution time stamps.
3966 * keyboard.c (start_polling, bind_polling_period):
3967 Check for time stamp overflow.
3968 (read_char, kbd_buffer_get_event, timer_start_idle)
3969 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3970 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3971 Port to higher-resolution time stamps. Do not assume time_t is signed.
3972 (decode_timer): New function. Timers are now vectors of length 9,
3973 not 8, to accommodate the picosecond component.
3974 (timer_check_2): Use it.
3976 * nsterm.m (select_timeout, timeval_subtract): Remove.
3977 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3978 as they're a bit more accurate and handle overflow better.
3979 (ns_select): Change prototype to be compatible with pselect.
3980 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3981 * nsterm.h (ns_select): Adjust prototype.
3983 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3984 us-resolution time stamps.
3985 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3987 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3989 * lisp.h (time_overflow): New decl.
3990 (wait_reading_process_output): First arg is now intmax_t, not int,
3991 to accommodate larger waits.
3993 * process.h (struct Lisp_Process.read_output_delay):
3994 Now counts nanoseconds, not microseconds.
3995 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3997 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3998 (wait_reading_process_output):
3999 Port to ns-resolution time stamps.
4000 (Faccept_process_output, wait_reading_process_output):
4001 Check for time stamp overflow. Do not assume time_t is signed.
4002 (select_wrapper): Remove; we now use pselect.
4003 (Fprocess_attributes): Now generates ns-resolution time stamps.
4005 * sysdep.c: Include utimens.h. Don't include utime.h
4006 or worry about struct utimbuf; gnulib does that for us now.
4007 (gettimeofday): Remove; gnulib provides a substitute.
4008 (make_timeval): New function.
4009 (set_file_times): Now sets ns-resolution time stamps.
4010 New arg FD; all uses changed.
4011 (time_from_jiffies, ltime_from_jiffies, get_up_time)
4012 (system_process_attributes):
4013 Now returns ns-resolution time stamp. All uses changed.
4014 Check for time stamp overflow.
4016 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
4017 provides a substitute now.
4019 * systime.h: Include timespec.h rather than sys/time.h and time.h,
4020 since it guarantees struct timespec.
4021 (EMACS_TIME): Now struct timespec, so that we can support
4022 ns-resolution time stamps.
4023 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
4024 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
4025 (EMACS_USECS): Remove.
4026 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
4027 so multiply the arg by 1000 before storing it.
4028 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
4030 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
4031 Port to ns-resolution time stamps.
4032 (EMACS_TIME_NEG_P): Remove; replaced by....
4033 (EMACS_TIME_SIGN): New macro.
4034 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
4035 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
4036 (set_file_times, make_time, lisp_time_argument): Adjust signature.
4037 (make_timeval, make_lisp_time, decode_time_components): New decls.
4038 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
4039 that it mishandled time_t overflow. You can't compare by subtracting!
4040 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
4041 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
4043 * term.c: Include <sys/time.h>.
4044 (timeval_to_Time): New function, for proper overflow wraparound.
4045 (term_mouse_position, term_mouse_click): Use it.
4047 * undo.c (record_first_change): Support higher-resolution time stamps
4049 (Fprimitive_undo): Use them when restoring time stamps.
4051 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
4052 (w32_get_internal_run_time):
4053 Port to higher-resolution Emacs time stamps.
4054 (ltime): Now accepts single 64-bit integer, as that's more convenient
4057 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
4059 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
4060 for compatibility with pselect. Support ns-resolution time stamps.
4062 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
4064 * xselect.c (wait_for_property_change, x_get_foreign_selection):
4065 Check for time stamp overflow, and support ns-resolution time stamps.
4067 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
4068 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
4069 (timeval_subtract): Remove; no longer needed.
4070 (XTflash, XTring_bell, x_wait_for_event):
4071 Port to ns-resolution time stamps. Don't assume time_t is signed.
4073 2012-06-22 Chong Yidong <cyd@gnu.org>
4075 * xdisp.c (x_consider_frame_title): Revert last change.
4077 2012-06-22 Eli Zaretskii <eliz@gnu.org>
4079 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
4080 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
4081 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
4082 staticidx goes up to 1597 out of 1600 = 0x640.)
4084 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
4086 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
4087 Otherwise, the umask might be mistakenly 0 while handling input signals.
4089 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
4091 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
4093 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>

4096 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
4097 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
4098 access to `contents' member of Lisp_Vector objects with AREF and ASET
4101 2012-06-19 Chong Yidong <cyd@gnu.org>
4103 * frame.c (delete_frame): When selecting a frame on a different
4104 text terminal, do not alter the terminal's top-frame.

4107 frame's selected window and its terminal's top-frame.
4108 (unwind_format_mode_line): Restore them.
4109 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
4111 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
4112 since tty frames can be explicitly named.

4354 code works fine either way, and efficiency is not a concern here,
4355 as the union type is for debugging, not for production.
4356 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
4357 Use an inline function on all platforms when using the union type,
4358 since this is simpler and 'static inline' can be used portably

4502 * doprnt.c (doprnt): Truncate multibyte char correctly.
4503 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4504 would mishandle a string argument "Xc" if X was a multibyte
4505 character of length 2: it would truncate after X's first byte
4506 rather than including all of X.

4593 * xdisp.c (handle_stop): Detect whether we have overlay strings
4594 loaded by testing it->current.overlay_string_index to be
4595 non-negative, instead of checking whether n_overlay_strings is
4596 positive. (Bug#11587)
4598 2012-05-31 Chong Yidong <cyd@gnu.org>
4600 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
4602 * doc.c (Fsubstitute_command_keys): Doc fix.
4604 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4606 * search.c (search_buffer): Remove calls to
4607 r_alloc_inhibit_buffer_relocation, as it is now called by
4608 maybe_unify_char, which was the cause of relocation of buffer text
4611 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4613 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4614 for the duration of call to load_charset, to avoid problems with
4615 callers of maybe_unify_char that access buffer text through C
4618 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4619 decrement the inhibition flag, instead of just setting or
4622 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4624 Remove obsolete '#define static' cruft.
4625 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
4626 This #undef was "temporary" in 2000; it is no longer needed
4627 now that '#define static' has gone away.
4628 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4629 (gray_bitmap_bits): Remove; no longer needed.
4630 All uses replaced with definiens.
4631 * xterm.c: Include "bitmaps/gray.xbm".
4633 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4635 Clean up __executable_start, monstartup when --enable-profiling.
4636 The following changes affect the code only when profiling.
4637 * dispnew.c (__executable_start): Rename from safe_bcopy.
4638 Define only on platforms that need it.
4639 * emacs.c: Include <sys/gmon.h> when profiling.
4640 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
4641 (__executable_start): Remove decl, since lisp.h does it now.
4642 (safe_bcopy): Remove decl; no longer has that name.
4643 (main): Coalesce #if into single bit of code, for simplicity.
4644 Cast pointers to uintptr_t, since standard libraries want integers
4646 * lisp.h (__executable_start): New decl.
4648 2012-05-31 Glenn Morris <rgm@gnu.org>
4650 * image.c (Fimagemagick_types): Doc fix.
4652 2012-05-30 Jim Meyering <meyering@redhat.com>
4654 * callproc.c (Fcall_process_region): Include directory component

4667 (Qdefun): Move from eval.c.
4668 * lisp.h (Qdefun): Remove.
4669 * lread.c (read1): Tiny simplification.
4671 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4673 Do not create empty overlays with the evaporate property (Bug#9642).
4674 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4675 Bug#9642, but explicitly check that the buffer the overlay would
4676 be moved to is live and rearrange lines to make sure that errors
4677 will not put the overlay in an inconsistent state.
4678 (Fdelete_overlay): Cosmetics.
4680 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4682 * w32term.c (my_bring_window_to_top): New function.
4683 (x_raise_frame): Use handle returned by DeferWindowPos, which
4684 could be different from the original one.
4685 Call my_bring_window_to_top instead of my_set_foreground_window.
4688 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4689 by calling BringWindowToTop.
4691 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4692 (WM_EMACS_END): Increase by one.
4694 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4696 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4697 This avoids undefined behavior that might cause the eassert
4698 to not catch an out-of-range value.
4700 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4702 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4703 Update dependencies.
4705 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4707 * bidi.c (bidi_mirror_char): Fix last change.
4709 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
4711 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
4712 when referring to sectname field in printf format.
4714 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4716 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4717 Only r_alloc_inhibit_buffer_relocation needed to be added;
4718 the others were already declared.
4720 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4721 before checking whether it's out of range. Put the check inside
4723 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4725 2012-05-27 Ken Brown <kbrown@cornell.edu>
4727 * callproc.c (Fcall_process): Restore a line that was accidentally
4728 commented out in the 2011-02-13 change (bug#11547).
4730 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4732 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4733 defined on ralloc.c.
4735 * buffer.c [REL_ALLOC]: Remove prototypes of
4736 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4737 they are now on lisp.h.
4739 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4741 * search.c (search_buffer): Use it to inhibit relocation of buffer
4742 text while re_search_2 is doing its job, because re_search_2 is
4743 passed C pointers to buffer text. (Bug#11519)
4745 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4748 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4749 state after an additional call to move_it_in_display_line_to, keep
4750 the values of it->max_ascent and it->max_descent found for the
4752 (pos_visible_p): Revert the comparison against bottom_y to what it
4753 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4756 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4758 Fix coding-related core dumps with gcc -ftrapv.
4759 The code was computing A - B, where A and B are pointers, and B is
4760 random garbage. This can lead to core dumps on platforms that
4761 have special pointer registers, and it also leads to core dumps on
4762 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4763 A - B only when B is initialized properly.
4764 * coding.c (coding_set_source, coding_set_destination): Return void.
4765 (coding_change_source, coding_change_destinations): New functions,
4766 with the old behaviors of coding_set_source and coding_set_destination.
4767 All callers that need an offset changed to use these new functions.
4769 2012-05-26 Glenn Morris <rgm@gnu.org>
4771 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4773 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4775 Extend mouse support on W32 text-mode console.
4776 * xdisp.c (draw_row_with_mouse_face):
4777 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4779 * w32console.c: Include window.h.
4780 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4782 (initialize_w32_display): Initialize mouse-highlight data.
4784 * w32inevt.c: Include termchar.h and window.h.
4785 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4786 moves, call note_mouse_highlight. If help_echo changed, call
4787 gen_help_event to produce help-echo message in the echo area.
4788 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4791 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4793 * lread.c (read1): Simplify slightly to avoid an overflow warning
4794 with GCC 4.7.0 on x86-64.
4796 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4798 * bidi.c (bidi_mirror_char): Revert last change: an int is
4799 definitely wide enough here.
4801 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4803 Fix integer width and related bugs (Bug#9874).
4804 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
4805 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
4806 (string_bytes, check_sblock, allocate_string_data):

4810 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
4811 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4813 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4814 (allocate_pseudovector):
4815 Use int, not EMACS_INT, where int is wide enough.
4816 (inhibit_garbage_collection, Fgarbage_collect):
4817 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4818 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4819 int might not be wide enough.
4820 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4821 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4822 (bidi_at_paragraph_end, bidi_find_paragraph_start)
4823 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4824 (bidi_level_of_next_char, bidi_move_to_visually_next):
4825 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4826 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4827 (Fkill_buffer, Fset_buffer_major_mode)
4828 (advance_to_char_boundary, Fbuffer_swap_text)
4829 (Fset_buffer_multibyte, overlays_at, overlays_in)
4830 (overlay_touches_p, struct sortvec, record_overlay_string)
4831 (overlay_strings, recenter_overlay_lists)
4832 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4833 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4834 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4835 (Foverlay_recenter, last_overlay_modification_hooks_used)
4836 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4837 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4838 (validate_region): Omit unnecessary test for b <= e,
4839 since that's guaranteed by the previous test.
4840 (adjust_overlays_for_delete): Avoid pos + length overflow.
4841 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4842 (report_overlay_modification):
4843 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4844 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4845 Omit pointer cast, which isn't needed anyway, and doesn't work
4846 after the EMACS_INT -> ptrdiff_t change.
4847 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4848 * buffer.h: Adjust decls to match defn changes elsewhere.
4849 (struct buffer_text, struct buffer):

4851 Use EMACS_INT, not int, where int might not be wide enough.
4852 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4853 not int, to avoid needless 32-bit limit on 64-bit hosts.
4854 (exec_byte_code): Use tighter memory-full test, one that checks
4855 for alloca overflow. Don't compute the address of the object just
4856 before an array, as that's not portable. Use EMACS_INT, not
4857 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4858 * callint.c (Fcall_interactively):
4859 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4860 * callproc.c (call_process_kill, Fcall_process):
4861 Don't assume pid_t fits into an Emacs fixnum.

4864 (call_process_cleanup, Fcall_process, delete_temp_file)
4865 (Fcall_process_region):
4866 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4867 (Fcall_process): Simplify handling of volatile integers.

4869 * casefiddle.c (casify_object, casify_region, operate_on_word)
4870 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4871 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4872 (casify_object): Avoid integer overflow when overallocating buffer.
4873 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4874 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4875 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4876 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4877 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4878 integers are now checked earlier. All uses replaced with XINT.
4880 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4881 For CCL_MapSingle, check that content and value are in int range.
4882 (ccl_driver, Fregister_code_conversion_map):
4883 Check that Vcode_version_map_vector is a vector.
4884 (resolve_symbol_ccl_program): Check that vector header is in range.
4885 Always copy the vector, so that we can check its contents reliably
4886 now rather than having to recheck each instruction as it's being
4887 executed. Check that vector words fit in 'int'.
4888 (ccl_get_compiled_code, Fregister_ccl_program)
4889 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4890 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4891 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4892 contents are in range.
4893 (Fccl_execute_on_string): Check that status is in range.
4894 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4895 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4896 Accept and return EMACS_INT, not int, because callers can pass values
4898 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4899 (multibyte_chars_in_text, parse_str_as_multibyte)
4900 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
4901 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4902 (string_escape_byte8, Fget_byte):
4903 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4904 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4905 avoid mishandling large integers.
4906 * character.h: Adjust decls to match defn changes elsewhere.
4907 * charset.c (load_charset_map_from_file, find_charsets_in_text)

4911 (load_charset_map_from_vector, Fdefine_charset_internal):
4912 Don't assume fixnum fits in int.
4913 (load_charset_map_from_vector, Fmap_charset_chars):
4914 Remove now-unnecessary CHECK_NATNUMs.
4915 (Fdefine_charset_internal): Check ranges here, more carefully.
4916 Don't rely on undefined behavior with signed left shift overflow.
4917 Don't assume unsigned int fits into fixnum, or that fixnum fits
4918 into unsigned int. Don't require max_code to be a valid fixnum;
4919 that's not true for gb10830 4-byte on a 32-bit host. Allow
4920 invalid_code to be a cons, for the same reason. Require code_offset
4921 to be a character. Avoid int overflow if max_char is close
4923 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4924 this is intended anyway and avoids some undefined behavior.
4925 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4926 INDEX_TO_CODE_POINT, as that's what it expects.
4927 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4928 * charset.h (DECODE_CHAR): Return int, not unsigned;
4929 this is what was intended anyway, and it avoids undefined behavior.
4930 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4931 integer-overflow issues.
4932 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4933 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4934 where the argument is EMACS_INT, and this behavior is not intended.
4935 * chartab.c (Fmake_char_table, Fset_char_table_range)
4936 (uniprop_get_decoder, uniprop_get_encoder):
4937 Don't assume fixnum fits in int.
4938 * cmds.c (move_point): New function, that does the gist of
4939 Fforward_char and Fbackward_char, but does so while checking
4940 for integer overflow more accurately.
4941 (Fforward_char, Fbackward_char): Use it.
4942 (Fforward_line, Fend_of_line, internal_self_insert)
4943 (internal_self_insert):
4944 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4945 Fix a FIXME, by checking for integer overflow when calculating
4946 target_clm and actual_clm.

4978 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4979 (consume_chars): Rewrite to not calculate an address outside buffer.
4980 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
4981 Don't access memory outside of the args array.
4982 (Fdefine_coding_system_internal): Check for charset-id overflow.
4983 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4984 result of ENCODE_CHAR.
4985 * coding.h: Adjust decls to match defn changes elsewhere.
4986 (struct coding_system):
4987 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

5730 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5732 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
5734 * unexaix.c: Port to more-recent AIX compilers.
5735 (report_error, report_error_1, make_hdr, copy_sym)
5736 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
5737 Make arguments const char *, not char *, to avoid violations of C
5738 standard and to fix some AIX warnings reported by Gilles Pion.
5740 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5742 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
5743 already have overlays loaded.
5744 (handle_single_display_spec): Before returning without displaying
5745 fringe bitmap, synchronize the bidi iterator with the main display
5746 iterator, by calling iterate_out_of_display_property.
5747 (iterate_out_of_display_property): Detect buffer iteration by
5748 testing that it->string is a Lisp string.
5749 (get_next_display_element): When the current object is exhausted,
5750 and there's something on it->stack, call set_iterator_to_next to
5751 proceed with what's on the stack, instead of returning zero.
5752 (set_iterator_to_next): If called at the end of a Lisp string,
5753 proceed to consider_string_end without incrementing string
5754 position. Don't increment display vector index past the end of
5755 the display vector. (Bug#11417)
5756 (pos_visible_p): Don't report a position visible when move_it_to
5757 stopped at the last line of window, which happens to be scanned
5758 backwards by the bidi iteration. (Bug#11464)
5760 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5762 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5763 and right-margin display specs even if the spec is invalid or we
5764 are on a TTY, and thus unable to display on the fringes.
5765 That's because the text with the property will not be displayed anyway,
5766 so we need to signal to the caller that this is a "replacing"
5767 display spec. This fixes display when the spec is invalid or we
5770 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5772 * unexaix.c (make_hdr): Fix typo in prototype.
5773 This bug broke the build on AIX. Problem reported by Gilles Pion.
5775 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5777 * keyboard.c (kbd_buffer_get_event): Read special events also in
5778 batch mode. (Bug#11415)
5780 2012-05-12 Glenn Morris <rgm@gnu.org>
5782 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5784 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5786 * lisp.mk (lisp): Add newcomment.elc.
5788 2012-05-12 Glenn Morris <rgm@gnu.org>
5790 * Makefile.in (MKDIR_P): New, set by configure.
5791 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5793 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5795 Remove unused function hourglass_started.
5796 * dispextern.h (hourglass_started):
5797 * w32fns.c (hourglass_started):
5798 * xdisp.c (hourglass_started): Remove.
5800 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5802 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5803 Update dependencies.
5805 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5807 * xgselect.c (xg_select): Put maxfds+1 into a var.
5808 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5810 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5812 2012-05-10 Dave Abrahams <dave@boostpro.com>
5814 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5815 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5817 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5819 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5820 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5821 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5822 Initialize xd_registered_buses.
5824 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5826 Untag more efficiently if USE_LSB_TAG.
5827 This is based on a proposal by YAMAMOTO Mitsuharu in
5828 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5829 For an admittedly artificial (nth 8000 longlist) benchmark on
5830 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5831 Emacs's overall text size by 1%.
5832 * lisp.h (XUNTAG): New macro.
5833 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5834 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5835 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5836 * eval.c (Fautoload):
5837 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5838 * frame.h (XFRAME): Use XUNTAG.
5840 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5841 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5842 Remove unportable assumptions about print widths of types like
5844 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5845 intptr_t when converting between pointer and integer, to avoid GCC
5846 warnings about wrong width.
5848 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5850 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5851 stack for each reader_thread, instead of defaulting to 8MB
5852 determined by the linker. This avoids failures in creating
5853 subprocesses on Windows 7, see the discussion in this thread:
5854 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5856 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5858 Fix up display of the *Minibuf-0* buffer in the mini window.
5859 * keyboard.c (read_char): Don't clear the echo area if there's no
5861 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5862 contents of *Minibuf-0*) if there's no message displayed in its stead.
5864 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5866 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5869 2012-05-06 Chong Yidong <cyd@gnu.org>
5871 * lisp.mk (lisp): Update.
5873 2012-05-05 Jim Meyering <meyering@redhat.com>
5875 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5877 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5879 * data.c (PUT_ERROR): New macro.
5880 (syms_of_data): Use it. Add new error type `user-error'.
5881 * undo.c (user_error): New function.
5882 (Fprimitive_undo): Use it.
5883 * print.c (print_error_message): Adjust print style for `user-error'.
5884 * keyboard.c (user_error): New function.
5885 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5887 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5889 Do not limit current-time-string to years 1000..9999.
5890 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5891 (Fcurrent_time_string): Support any year that is supported by the
5892 underlying localtime representation. Don't use asctime, as it
5893 has undefined behavior for years outside the range -999..9999.
5895 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5897 Fix race conditions involving setenv, gmtime, localtime, asctime.
5898 Without this fix, interrupts could mess up code that uses these
5899 nonreentrant functions, since setting TZ invalidates existing
5900 tm_zone or tzname values, and since most of these functions return
5901 pointers to static storage.
5902 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5903 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5904 Grow the critical sections to include not just invoking
5905 localtime/gmtime, but also accessing these functions' results
5906 including their tm_zone values if any, and any related TZ setting.
5907 (format_time_string): Last arg is now struct tm *, not struct tm **,
5908 so that the struct tm is saved in the critical section.
5909 All callers changed. Simplify allocation of initial buffer, partly
5910 motivated by the fact that memory allocation needs to be outside
5911 the critical section.
5913 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5915 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5916 with RESET_INTERVAL.
5918 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5919 Remove duplicated buffer name initialization.
5921 2012-05-02 Jim Meyering <jim@meyering.net>
5923 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5925 * xfns.c (x_window): Use xstrdup (Bug#11375).
5927 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5929 * xdisp.c (pos_visible_p): If already at a newline from the
5930 display string before the 'while' loop, don't walk back the glyphs
5931 from it3.glyph_row. Solves assertion violation when the display
5932 string begins with a newline (egg.el). (Bug#11367)
5934 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5936 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5939 2012-05-01 Glenn Morris <rgm@gnu.org>
5941 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5942 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5943 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5944 All were removed before 23.1.
5946 * dispnew.c: Remove HAVE_LIBNCURSES test;
5947 it is always true on relevant platforms.
5949 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5950 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5952 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5954 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5956 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5957 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5960 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5962 Do not avoid creating empty evaporating overlays (Bug#9642).
5963 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5964 That is, do not delete an evaporating overlay if it becomes
5965 empty after its bounds are adjusted to fit within its buffer.
5966 This fix caused other problems, and I'm reverting it until we get
5967 to the bottom of them.
5969 2012-04-27 Chong Yidong <cyd@gnu.org>
5971 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5973 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5975 * xdisp.c (pos_visible_p): If the window start position is beyond
5976 ZV, start the display from buffer beginning. Prevents assertion
5977 violation in init_iterator when the minibuffer window is scrolled
5980 * window.c (window_scroll_pixel_based): Likewise.
5982 2012-04-27 Chong Yidong <cyd@gnu.org>
5984 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5986 2012-04-27 Glenn Morris <rgm@gnu.org>
5988 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5989 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5991 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5993 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5994 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5996 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5998 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5999 display element, check also the underlying string or buffer
6000 character. (Bug#11341)
6002 * w32menu.c: Include w32heap.h.
6003 (add_menu_item): If the call to AppendMenuW (via
6004 unicode_append_menu) fails, disable Unicode menus only if we are
6005 running on Windows 9X/Me.
6007 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
6009 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
6010 (xgetint): Add missing shift for LSB tags.
6012 2012-04-24 Martin Rudalics <rudalics@gmx.at>
6014 * keyboard.c (read_char): Don't wipe echo area for select window
6015 events: These might get delayed via `mouse-autoselect-window'
6018 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
6020 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
6021 manipulation of :loaded-from data.
6023 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
6025 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
6026 now a cons (bug#11311).
6028 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
6030 Do not create empty overlays with the evaporate property (Bug#9642).
6031 * buffer.c (Fmove_overlay): Delete an evaporating overlay
6032 if it becomes empty after its bounds are adjusted to fit within
6033 its buffer. Without this fix, in a nonempty buffer (let ((o
6034 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
6035 yields an empty overlay that has the evaporate property, which is
6036 not supposed to happen.
6038 Fix minor GTK3 problems found by static checking.
6039 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
6040 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6041 (struct _EmacsFixedClass, emacs_fixed_get_type):

6044 (emacs_fixed_class_init): Omit unused local.
6045 (emacs_fixed_child_type): Remove; unused.

6048 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
6049 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
6050 (EMACS_FIXED_GET_CLASS): Remove; unused.
6051 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
6053 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
6054 Problem reported by Juanma Barranquero for Windows -Wunused-function.
6056 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6058 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
6059 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
6060 (__malloc_size_t, __malloc_ptrdiff_t):
6061 Remove. All uses removed, replaced by the definiens if needed,
6062 since we can assume C89 or better now.
6063 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
6064 (protect_malloc_state, align, get_contiguous_space)
6065 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
6066 (malloc_atfork_handler_child, malloc_enable_thread)

6071 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
6072 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
6073 Define using prototypes, not old style.
6074 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
6075 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
6076 (align): Don't assume that signed integer overflow wraps around.
6077 Omit unused local var.
6078 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
6079 (_free_internal_nolock, memalign, mallochook, reallochook):
6080 Omit no-longer-needed casts.
6081 (valloc): Use getpagesize, not __getpagesize.
6082 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
6083 (struct hdr): The 'magic' member is now size_t, not unsigned long.
6085 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
6087 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
6089 Move functions from C to Lisp. Make non-blocking method calls
6090 the default. Implement further D-Bus standard interfaces.

6129 (Vdbus_registered_buses, Vdbus_registered_objects_table):
6132 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6134 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
6135 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
6136 Do not assume ptrdiff_t is the same width as 'int'.
6138 * alloc.c: Handle unusual debugging option combinations.
6139 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
6140 since the two debugging options are incompatible.
6141 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
6143 (mem_init, mem_insert, mem_insert_fixup):
6144 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
6145 (NEED_MEM_INSERT): Remove; no longer needed.
6147 2012-04-22 Leo Liu <sdl.web@gmail.com>
6149 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
6151 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6153 * sysdep.c [__FreeBSD__]: Minor cleanups.
6154 (list_system_processes, system_process_attributes) [__FreeBSD__]:
6155 Use Emacs indenting style more consistently. Avoid some casts.
6156 Use 'double' consistently rather than mixing 'float' and 'double'.
6158 2012-04-21 Eduard Wiebe <usenet@pusto.de>
6160 * sysdep.c (list_system_processes, system_process_attributes):
6161 Add implementation for FreeBSD (Bug#5243).
6163 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>
6165 * lisp.mk (lisp): Update.
6167 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
6169 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
6170 It is never used otherwise.

6174 * print.c (print_preprocess): Only check print_depth if print-circle
6176 (print_object): Check for cycles even when print-circle is nil and

6179 2012-04-20 Chong Yidong <cyd@gnu.org>
6181 * process.c (wait_reading_process_output): If EIO occurs on a pty,

6195 row, return zero immediately.
6196 (try_cursor_movement): If inside continuation line, don't back up
6197 farther than the first row after the header line, if any.
6198 Don't consider the header-line row as "partially visible", even if
6199 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
6201 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

6215 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
6216 -Wunused-result, -Wunused-variable. This should go away once
6217 the Emacs and Gnulib regex code is merged.

6236 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
6237 New extern decls, to avoid calling undeclared functions.
6238 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
6239 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
6240 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
6241 (NEED_MEM_INSERT): New macro.
6242 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
6243 Remove one incorrect comment and fix another.

6249 (r_alloc_sbrk): Now static.
6251 Improve ralloc.c interface checking.
6252 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

6257 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
6258 Remove decls. This fixes an "It stinks!".
6260 * alloc.c (which_symbols): Fix alignment issue / type clash.
6262 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
6264 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

6277 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
6278 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
6279 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
6280 * s/netbsd.h, s/sol2-6.h:
6281 Remove definition of GC_MARK_STACK, since the default now works.
6282 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
6283 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
6284 no longer the default.
6285 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
6287 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
6289 * lread.c (lisp_file_lexically_bound_p):

6299 * nsterm.m (constrainFrameRect): Always constrain when there is only
6300 one screen (Bug#10962).

6310 2012-04-11 Daniel Colascione <dancol@dancol.org>
6312 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
6313 against is gone. It's better to use vfork now so that when Cygwin
6314 gains a new, working vfork, we use it automatically (bug#10398).
6316 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

6332 (handle_interrupt): Use it.
6334 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
6336 * w32.c (w32_delayed_load): Record the full path of the library
6337 being loaded (bug#10424).
6339 2012-04-09 Glenn Morris <rgm@gnu.org>
6341 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
6342 not just in the obarray, before snarfing them. (Bug#11036)
6344 * Makefile.in ($(leimdir)/leim-list.el):
6345 Pass EMACS rather than BUILT_EMACS.

6354 Add convenience `GNUTLS_LOG2i' macro.
6356 * gnutls.c (gnutls_log_function2i): Convenience log function.
6357 (emacs_gnutls_read): Use new log functions,
6358 `gnutls_handshakes_tried' process member, and

6369 * minibuf.c (Fread_variable): Callers changed.
6371 2012-04-09 Eli Zaretskii <eliz@gnu.org>
6373 * xdisp.c (set_cursor_from_row): If the display string appears in
6374 the buffer at position that is closer to point than the position
6375 after the display string, display the cursor on the first glyph of
6376 the display string. Fixes cursor display when a 'display' text
6377 property immediately follows invisible text. (Bug#11094)
6379 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
6381 composite.c: use 'double' consistently
6382 * composite.c (get_composition_id): Use 'double' consistently
6383 instead of converting 'float' to 'double' and vice versa; this is
6384 easier to understand and avoids a GCC warning.
6386 2012-04-09 Glenn Morris <rgm@gnu.org>
6388 * Makefile.in: Generate leim-list with bootstrap-emacs, in
6389 preparation for dumping it with emacs. (Bug#4789)

6411 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
6412 (mark_memory): Mark Lisp_Objects only if pointers might hide in
6413 objects, as mark_maybe_pointer will catch them otherwise.
6414 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
6415 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
6417 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
6419 Fix typo that broke non-Windows builds.
6420 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
6422 2012-04-07 Eli Zaretskii <eliz@gnu.org>
6424 Support building on MS-Windows with libxml2.
6426 * makefile.w32-in (OBJ2): Add xml.$(O).

6430 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
6431 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
6432 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
6433 [!WINDOWSNT]: New macros.
6434 (init_libxml2_functions, libxml2_loaded_p): New functions.
6435 (parse_region): Call fn_xmlCheckVersion instead of using the macro
6436 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
6437 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
6438 Calls xmlCleanupParser only if libxml2 was loaded (or statically
6440 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
6441 Call init_libxml2_functions before calling libxml2 functions.
6442 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
6444 * emacs.c: Don't include libxml/parser.h.
6445 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
6446 xmlCleanupParser directly.
6448 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
6450 2012-04-07 Eli Zaretskii <eliz@gnu.org>
6452 * indent.c (Fvertical_motion): If there is a display string at
6453 point, use it.vpos to compute how many lines to backtrack after

6458 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
6459 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
6460 about subtle differences between FETCH_CHAR* and STRING_CHAR*
6461 macros related to unification of CJK characters. For the details,
6462 see the discussion following the message here:
6463 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6465 2012-04-04 Chong Yidong <cyd@gnu.org>
6467 * keyboard.c (Vdelayed_warnings_list): Doc fix.
6469 2012-04-01 Eli Zaretskii <eliz@gnu.org>
6471 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

6479 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6481 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6482 position we get to after a call to move_it_to fails the
6483 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6484 only if we wind up in a string from display property. (Bug#11063)
6486 * window.c (Fdelete_other_windows_internal): Invalidate the row
6487 and column information about mouse highlight, so that redisplay
6488 restores it after reallocating the glyph matrices. (Bug#7464)
6490 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6491 string comes from a `display' text property, use the buffer
6492 position of that property as if we actually saw that position in
6494 (move_it_by_lines): Remove the assertion that
6495 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6496 violated when there's a before-string at the beginning of a line.
6499 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6501 * xdisp.c (append_space_for_newline): If the default face was
6502 remapped, use the remapped face for the appended newline.
6503 (extend_face_to_end_of_line): Use the remapped default face for
6504 extending the face to the end of the line.
6505 (display_line): Call extend_face_to_end_of_line when the default
6506 face was remapped. (Bug#11068)
6508 2012-03-29 Eli Zaretskii <eliz@gnu.org>

6530 handle-select-window too (Bug#8996).
6532 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
6534 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
6536 2012-03-25 Kenichi Handa <handa@m17n.org>
6538 * dispextern.h (struct glyph): Change the bit length of
6539 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6541 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6543 * s/ms-w32.h (tzname): Include time.h before redirecting to
6544 _tzname. Fixes the MSVC build. (Bug#9960)

6548 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6551 * xterm.c (XTread_socket): Only modify handling_signal if
6552 !SYNC_INPUT. (Bug#11080)
6554 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6556 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6557 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6558 when fetching a multibyte character consumes more bytes than
6559 CHAR_BYTES returns, due to unification of CJK characters in
6560 string_char. (Bug#11073)
6562 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6564 * process.c (wait_reading_process_output): Handle pty disconnect
6565 by refraining from sending oneself a SIGCHLD (bug#10933).

6576 2012-03-21 Chong Yidong <cyd@gnu.org>
6578 * xfaces.c (Vface_remapping_alist): Doc fix.
6580 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6582 * w32proc.c (Fw32_set_console_codepage)
6583 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

6594 it fit in a valid range (Bug#11003).
6596 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6598 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6599 that is not from display property, accept the row as a "cursor
6600 row" if one of the string's character has a non-nil `cursor'
6601 property. Fixes cursor positioning when there are newlines in
6602 overlay strings, e.g. in icomplete.el. (Bug#11035)
6604 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6606 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

6610 * eval.c (inhibit_lisp_code): Rename from
6611 inhibit_window_configuration_change_hook; move from window.c.
6613 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6614 * window.c (run_window_configuration_change_hook)
6615 (syms_of_window): Callers changed.
6617 2012-03-11 Chong Yidong <cyd@gnu.org>
6619 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6621 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
6623 2012-03-10 Chong Yidong <cyd@gnu.org>

6626 is visible (Bug#10955).
6628 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
6630 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6632 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6634 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6635 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6638 2012-03-03 Glenn Morris <rgm@gnu.org>
6640 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6642 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6644 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6645 position past the first glyph_row that ends at ZV. (Bug#10902)
6646 (redisplay_window, next_element_from_string): Fix typos in
6648 (redisplay_window): Pass to move_it_vertically the margin in
6649 pixels, not in screen lines.
6651 2012-03-02 Glenn Morris <rgm@gnu.org>
6653 * buffer.c (buffer-list-update-hook): Doc fix.
6655 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6657 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6658 push_it before setting up the iterator for the first overlay
6659 string, even if we have an empty string loaded.
6660 (next_overlay_string): If there's an empty string on the iterator
6661 stack, pop the stack. (Bug#10903)
6663 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6665 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6666 Suggested by Stefan Monnier in
6667 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6668 * alloc.c (widen_to_Lisp_Object): New static function.
6669 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6670 and widening them to Lisp_Objects. This would work even if
6671 USE_LSB_TAG is defined and wide integers are used, which might
6672 happen in a future version of Emacs.
6674 2012-02-25 Chong Yidong <cyd@gnu.org>
6676 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6679 * xselect.c (Fx_selection_exists_p): Doc fix.
6680 (x_clipboard_manager_save_all): Print an informative message
6681 before saving to clipboard manager.
6683 2012-02-24 Chong Yidong <cyd@gnu.org>
6685 * keyboard.c (process_special_events): Handle all X selection
6686 requests in kbd_buffer, not just the next one (Bug#8869).
6688 2012-02-23 Chong Yidong <cyd@gnu.org>
6690 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
6691 call when setting menu-bar-lines and tool-bar-lines parameters.
6692 (unwind_create_frame_1): New helper function.
6694 * window.c (inhibit_window_configuration_change_hook): New var.
6695 (run_window_configuration_change_hook): Obey it.
6696 (syms_of_window): Initialize it.
6698 2012-02-22 Chong Yidong <cyd@gnu.org>
6700 * xterm.c (x_draw_image_relief): Add missing type check for

6712 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
6713 when computing $valmask.
6715 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6716 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6717 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6718 It's useless in that case, and it can cause problems on hosts
6719 that allocate halves of EMACS_INT values separately.
6720 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6721 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6722 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6723 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6724 it avoids undefined behavior on hosts where shifting right by more
6725 than the word width has undefined behavior.
6727 2012-02-19 Chong Yidong <cyd@gnu.org>
6729 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

6772 * window.c (Fdelete_window_internal): Invalidate the mouse
6773 highlight (Bug#9904).
6775 2012-02-12 Glenn Morris <rgm@gnu.org>

6805 2012-02-07 Chong Yidong <cyd@gnu.org>
6807 * buffer.c (Fbuffer_local_variables)
6808 (buffer_lisp_local_variables): Handle unbound vars correctly;
6809 don't let Qunbound leak into Lisp.
6811 2012-02-07 Glenn Morris <rgm@gnu.org>
6813 * image.c (Fimagemagick_types): Doc fix.
6815 * image.c (imagemagick-render-type): Change it from a lisp object

6851 * character.c (char_width): Return EMACS_INT, not int.
6852 (char_width, c_string_width): Check for overflow when
6853 computing the width; this is possible now that individual
6854 characters can have unbounded width. Problem introduced
6855 by merge from Emacs 23 on 2012-01-19.
6857 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

7527 behave as if the cursor position were at the window margin.
7529 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7530 and the cursor position is out of bounds, behave as if the cursor

7561 * dispnew.c (verify_row_hash): Call row_hash for computing the
7562 hash code of a row, instead of duplicating code from xdisp.c.
7564 * dispextern.h (row_hash): Add prototype.
7566 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

7671 Avoid some portability problems by eschewing 'extern inline' functions.
7672 The trivial performance wins aren't worth the portability hassles; see
7673 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
7675 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

7677 (window_box_right, window_box_right_offset): Undo previous change,
7678 by removing the "extern"s.
7679 * intervals.c (adjust_intervals_for_insertion)
7680 (adjust_intervals_for_deletion): Undo previous change,
7681 making these static again.
7682 (offset_intervals, temp_set_point_both, temp_set_point)
7683 (copy_intervals_to_string): No longer inline.

7702 2011-11-07 Eli Zaretskii <eliz@gnu.org>
7704 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
7705 if Vpurify_flag is non-nil. Fixes a crash when running w32 build
7706 of temacs in GUI mode.
7708 2011-11-07 Martin Rudalics <rudalics@gmx.at>
7710 * window.h: Declare delete_all_child_windows instead of

7723 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7724 This is also needed for porting to any host where GC_MARK_STACK is
7725 not GC_MAKE_GCPROS_NOOPS.
7726 (which_symbols): Use it.
7728 2011-11-07 Kenichi Handa <handa@m17n.org>

7741 * xmenu.c (cleanup_widget_value_tree): New function.
7742 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

7747 Fix some portability problems with 'inline'.
7748 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
7749 (window_box_width, window_box_left, window_box_left_offset)
7750 (window_box_right, window_box_right_offset): Declare extern.
7751 Otherwise, these inline functions do not conform to C99 and
7752 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7753 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7754 * intervals.c (adjust_intervals_for_insertion)
7755 (adjust_intervals_for_deletion): Now extern, because otherwise the
7756 extern inline functions 'offset_intervals' couldn't refer to it.
7757 (static_offset_intervals): Remove.
7758 (offset_intervals): Rewrite using the old contents of
7759 static_offset_intervals. The old version didn't conform to C99
7760 because an extern inline function contained a reference to an
7761 identifier with static linkage.
7763 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
7765 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

7783 (Fwindow_vscroll): Doc fix.
7784 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
7785 argument, since it makes no sense to pass a live window and for
7786 consistency with window-child.

7814 (unwind_create_frame): New function (Bug#9943).
7815 (Fx_create_frame): Restructure code to be more similar to the one in
7816 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
7817 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
7818 Move terminal->reference_count++ just before making the frame official

7932 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
7933 so that this new function doesn't get optimized away by a
7934 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
7936 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>

7961 2011-10-28 Eli Zaretskii <eliz@gnu.org>
7963 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

8073 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
8074 * editfns.c: Rewrite current-time-zone so that it invokes
8075 the equivalent of (format-time-string "%Z") to get the time zone name.
8076 This fixes a bug when the time zone name contains characters that
8077 need converting from the system time locale to Emacs internal format.
8078 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
8079 that patch fixed format-time-string to do the conversion, but
8080 I forgot to fix current-time-zone.
8081 (format_time_string): New function, containing most of
8082 what Fformat_time_string used to contain.
8083 (Fformat_time_string): Rewrite in terms of format_time_string.

8087 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
8088 Jason Rumney's 2007-06-07 change worked around this bug, but
8090 * systime.h (tzname, timezone): Remove no-longer-used declarations.
8092 2011-10-19 Eli Zaretskii <eliz@gnu.org>
8094 * xdisp.c (start_display): If the character at POS is displayed
8095 via a display vector, reset IT->current.dpvec_index to zero.
8096 (try_window_reusing_current_matrix): If a line ends in a display
8097 vector or the next line starts in a display vector, continue
8098 redrawing the window even though the character position of
8099 start_row was reached.
8102 2011-10-18 Chong Yidong <cyd@gnu.org>
8104 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
8105 with nobreak-char-display too.
8107 2011-10-18 Eli Zaretskii <eliz@gnu.org>
8109 Fix part 3 of bug#9771.
8110 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
8111 (bidi_resolve_neutral): Don't enter the expensive loop looking for
8112 non-neutral characters if the current character is a paragraph
8113 separator (a.k.a. Newline). This avoids running the same
8114 expensive loop twice, once when we consume the preceding newline
8115 and the other time when the line actually needs to be displayed.
8116 Avoid the loop when we see neutrals on the base embedding level
8117 following a character whose directionality is the same as the
8118 paragraph's. This avoids running the expensive loop when a line
8119 ends in a long sequence of neutrals, like control characters.
8120 Add assertion against STRONG_AL type. Slightly rearrange code
8121 that determines the type of a neutral given the first non-neutral
8123 (bidi_level_of_next_char): Set next_en_pos to zero when
8124 invalidating its info.
8126 2011-10-17 Eli Zaretskii <eliz@gnu.org>
8128 * xdisp.c (push_display_prop): Determine whether to record string
8129 or buffer position by IT->string, not by IT->method. Allow
8130 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
8131 (move_it_vertically_backward): Don't look for character position
8132 immediately after the newline when in a continuation line.
8135 2011-10-15 Martin Rudalics <rudalics@gmx.at>
8137 * window.c (coordinates_in_window): Rewrite and delabelize
8138 vertical border check. (Bug#5357) (Bug#9618)
8140 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
8142 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
8143 errors in XSetWindowBorder (bug#9310).
8145 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
8147 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
8148 avoid crash when xmalloc overrun checking is enabled.
8150 2011-10-13 Eli Zaretskii <eliz@gnu.org>
8152 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
8153 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
8154 cursor motion with <left> and <right> arrow keys.
8156 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
8157 some callers set that themselves.
8159 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8161 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
8162 display string and the previous row comes from the same string and
8163 is empty. (Bug#9739) (Bug#9738)
8165 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
8167 * doc.c (get_doc_string): Encode file name (bug#9735).
8169 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8171 * bidi.c (bidi_level_of_next_char):
8172 * xdisp.c (get_visually_first_element): Remove old incorrect
8173 comments regarding the Unicode Line Separator character.
8175 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
8177 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
8179 * alloc.c (Fgc_status): Do not access beyond zombies array
8180 boundary if nzombies > MAX_ZOMBIES.
8181 * alloc.c (dump_zombies): Add missing format specifier.
8183 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
8185 * xdisp.c (set_cursor_from_row): Simplify conditionals,
8186 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
8188 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
8189 Some packages use them to denote characters with modifiers.
8191 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
8193 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
8194 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
8195 matching a pp-number. Rename parameter var to var1.
8197 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
8199 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
8201 2011-10-08 Glenn Morris <rgm@gnu.org>
8203 * callint.c (Fcall_interactively): Give a more explicit error for the
8204 'c' case with a non-character input. (Bug#8479)
8206 2011-10-08 Eli Zaretskii <eliz@gnu.org>
8208 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
8210 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
8211 lines that are hscrolled on the left.
8213 * dispnew.c (buffer_posn_from_coords): Account for a possible
8214 presence of header-line. (Bug#4426)
8216 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
8218 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
8219 Don't advertise functionality which we discourage or doesn't work.
8221 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
8223 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
8224 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
8225 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
8226 this makes Emacs dump core during garbage collection on rare
8227 occasions. sizeof is obviously inferior to offsetof here, so
8228 stick with offsetof.
8229 (GC_POINTER_ALIGNMENT): New macro.
8230 (mark_memory): Omit 3rd (offset) arg; caller changed.
8231 Don't assume EMACS_INT alignment is the same as pointer alignment.
8233 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
8235 * keyboard.c (read_key_sequence_remapped): New var.
8236 (read_key_sequence): Compute remapping in the right buffer.
8237 (command_loop_1): Use read_key_sequence's remapping directly.
8239 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
8241 * dired.c (file_name_completion): Don't expand file name.
8242 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
8243 before checking file name handler.
8245 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
8246 they've been requested explicitly (bug#9591).
8248 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
8250 * keymap.c (Fsingle_key_description): Use make_specified_string
8251 instead of build_string to build string from push_key_description.
8254 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8256 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
8257 This fixes a Y2038 bug on 64-bit hosts.
8258 * buffer.c (reset_buffer):
8259 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
8260 (Fclear_buffer_auto_save_failure):
8261 Use 0, not -1, to represent an unset failure time, since time_t
8262 might not be signed.
8264 Remove dependency on glibc malloc internals.
8265 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8266 Move back here from lisp.h, but with their new implementations.
8267 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8268 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
8269 * charset.c (charset_table_init): New static var.
8270 (syms_of_charset): Use it instead of xmalloc. This removes a
8271 dependency on glibc malloc internals. See Eli Zaretskii's comment in
8272 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
8273 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8274 Move back to alloc.c.
8275 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8276 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
8278 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
8280 * nsterm.m (windowDidResize): Call x_set_window_size only when
8281 ns_in_resize is true. Otherwise set pixelwidth/height and
8282 call change_frame_size (Bug#9628).
8284 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8286 Port --enable-checking=all to Fedora 14 x86-64.
8287 * charset.c (syms_of_charset): Also account for glibc malloc's
8288 internal overhead when calculating the initial malloc maximum.
8290 Port --enable-checking=all to Fedora 14 x86.
8291 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8293 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
8294 (overrun_check_realloc, overrun_check_free):
8295 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
8296 That way, xmalloc returns a properly-aligned pointer even if
8297 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
8298 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
8299 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
8300 into account when calculating the initial malloc maximum.
8301 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8302 Move here from alloc.c, so that charset.c can use it too.
8303 Properly align; the old code wasn't right for common 32-bit hosts
8304 when configured with --enable-checking=all.
8305 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8306 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
8308 2011-09-29 Eli Zaretskii <eliz@gnu.org>
8310 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
8313 2011-09-28 Eli Zaretskii <eliz@gnu.org>
8315 * xdisp.c (compute_display_string_end): If there's no display
8316 string at CHARPOS, return -1.
8318 * bidi.c (bidi_fetch_char): When compute_display_string_end
8319 returns a negative value, treat the character as a normal
8320 character not covered by a display string. (Bug#9624)
8322 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
8324 * lread.c (Fread_from_string): Fix typo in docstring.
8326 2011-09-27 Eli Zaretskii <eliz@gnu.org>
8328 * xdisp.c (handle_invisible_prop): If invisible text ends on a
8329 newline, reseat the iterator instead of bidi-iterating there one
8330 character at a time. (Bug#9610)
8331 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
8332 TO_CHARPOS if the bidi iterator is at base embedding level.
8334 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
8336 * lread.c (readevalloop): Use correct code for NBSP.
8337 (read1): Likewise. (Bug#9608)
8339 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
8341 * dbusbind.c (Fdbus_register_signal): When service is not
8342 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
8344 2011-09-25 Glenn Morris <rgm@gnu.org>
8346 * buffer.c (truncate-lines): Doc fix.
8348 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
8350 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
8351 (Fset_window_next_buffers): Doc fix.
8353 2011-09-24 Glenn Morris <rgm@gnu.org>
8355 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
8357 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
8359 Fix minor problems found by static checking.
8360 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
8361 * indent.c (Fvertical_motion): Fix == vs = typo.
8363 2011-09-24 Eli Zaretskii <eliz@gnu.org>
8365 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
8366 Default value is now t. Doc fix.
8368 * indent.c (Fvertical_motion): Compute and apply the overshoot
8369 logic when moving up, not only when moving down. Fix the
8370 confusing name and values of the it_overshoot_expected variable;
8371 logic changes accordingly. (Bug#9254) (Bug#9549)
8373 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
8374 CHARPOS is covered by a display string which includes newlines.
8375 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
8376 is covered by a display string with embedded newlines.
8378 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
8380 * dbusbind.c (Fdbus_register_signal): Add match rule to
8381 Vdbus_registered_objects_table. (Bug#9581)
8382 (Fdbus_register_method, Vdbus_registered_objects_table):
8385 2011-09-24 Jim Meyering <meyering@redhat.com>
8387 do not ignore write error for any output size
8388 The previous change was incomplete.
8389 While it makes emacs --batch detect the vast majority of stdout
8390 write failures, errors were still ignored whenever the output size is
8391 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
8392 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
8393 && echo FAIL: ignored write error
8394 FAIL: ignored write error
8395 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
8396 && echo FAIL: ignored write error
8397 FAIL: ignored write error
8398 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
8400 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

8403 non-successfully if a write error occurred on stdout. (Bug#9574)
8405 2011-09-21 Eli Zaretskii <eliz@gnu.org>
8407 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
8410 * dispextern.h (struct it): Update the comment documenting what
8413 2011-09-20 Eli Zaretskii <eliz@gnu.org>
8415 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
8416 a display string, extend search for cursor position to end of row.
8417 (find_row_edges): If the row ends in a newline from a display
8418 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
8419 Handle the case of a display string with multiple newlines.
8420 (Fcurrent_bidi_paragraph_direction): Fix search for previous
8421 non-empty line. Fixes confusing cursor motion with arrow keys at
8422 the beginning of a line that starts with whitespace.

8434 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8436 * xdisp.c (display_line): Record maximum and minimum buffer
8437 positions even if no glyphs were produced (e.g., by a zero-width
8438 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
8439 buffer positions that will be removed from the glyph row because
8441 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
8442 column is beyond frame width: don't subtract 1 "pixel" when
8443 computing width of the stretch.
8444 (reseat_at_next_visible_line_start): Undo the change made on
8445 2011-09-17 that saved paragraph information and restored it after
8446 the call to `reseat'. (Bug#9545)
8448 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8450 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
8451 and turn window cursor on if cleared (Bug#9415).

8464 Fix minor problem found by static checking.
8465 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8466 initialized, to pacify gcc -Wuninitialized.
8468 * fileio.c: Report proper errno when syscall falls.
8469 (Finsert_file_contents): Save and restore errno,
8470 so that report_file_error outputs the correct diagnostic.
8471 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8473 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8475 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
8477 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8479 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
8480 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
8482 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8484 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8485 about the current paragraph and restore it after the call to reseat.
8487 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
8488 (bidi_find_paragraph_start): Search back for paragraph beginning
8489 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
8490 (bidi_move_to_visually_next): Only trigger paragraph-related
8491 computations when the last character is a newline or at EOB, not
8492 just any NEUTRAL_B. (Bug#9470)
8494 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
8495 truncated lines if point is covered by a display string. (Bug#9524)
8497 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8499 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8500 (cons_to_x_long): New function.
8501 (lisp_data_to_selection_data): Use it. Correct the test for
8502 short-versus-long data; it was negated. Break out of vector
8503 loop, for efficiency, when a long datum is discovered.
8505 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8507 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8509 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8511 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

8535 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8536 This occurs when processing a multibyte format.
8537 Problem reported by Wolfgang Jenker.
8539 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8541 * xdisp.c (try_cursor_movement): Only check for exact match if
8542 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8544 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8546 Remove unused external symbols.

8554 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8556 * xselect.c: Use signed conversions more consistently (Bug#9498).
8557 (selection_data_to_lisp_data): Assume incoming selection data are
8558 signed integers, not unsigned. This is to be consistent with
8559 outgoing selection data, which was modified to use signed integers
8560 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8561 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8562 expects long, not unsigned long.

8590 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8592 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8594 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8595 value for non-existent files.
8597 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8599 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8600 set its "size" to -1. This will set the modtime_size field of
8601 the corresponding buffer to -1, which is what
8602 verify-visited-file-modtime expects for files that do not exist.
8605 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8607 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8609 * lisp.h: ... from here. push_key_description is no longer
8610 defined in keyboard.c, so its declaration should not be in
8611 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8612 logically belongs with push_key_description.
8614 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8616 * buffer.h: Include <sys/types.h> instead of <time.h>.
8617 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8618 Problem reported by Herbert J. Skuhra.
8620 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8622 * xml.c (parse_region): Make the parsing work for
8623 non-comment-starting XML files again (bug#9144).
8625 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8627 * image.c (gif_load): Fix calculation of bottom and right corner.
8630 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8632 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8633 redisplay in small windows.
8635 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8637 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8639 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8641 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8642 Operate on live windows only.
8644 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8646 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8648 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8650 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8651 only under bidi iteration.
8653 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8655 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8657 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8659 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8660 Without this fix, the command to link temacs failed due to an
8661 undefined symbol __builtin_isnan. This is because
8662 /usr/include/iso/math_c99.h #defines isnan(x) to
8663 __builtin_isnan(x), but the bundled gcc, which identifies itself
8664 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8666 * floatfns.c (isnan): #undef, and then #define to a clone of
8668 (Fisnan): Always define, since it's always available now.
8669 (syms_of_floatfns): Always define isnan at the Lisp level.
8671 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8673 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8675 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8677 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8678 The previous code assumed that file offsets (off_t values) fit in
8679 EMACS_INT variables, which is not true on typical 32-bit hosts.
8680 The code messed up by falsely reporting buffer overflow in cases
8681 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8682 when "big" contains more than 2**29 bytes, even though this
8683 inserts just one byte and does not overflow the buffer.
8684 (Finsert_file_contents): Store file offsets as off_t
8685 values, not as EMACS_INT values. Check for overflow when
8686 converting between EMACS_INT and off_t. When checking for
8687 buffer overflow or for overlap, take the offsets into account.
8688 Don't use EMACS_INT for small values where int suffices.
8689 When checking for overlap, fix a typo: ZV was used where
8690 ZV_BYTE was intended.
8691 (Fwrite_region): Don't assume off_t fits into 'long'.
8692 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8694 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8696 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8698 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8700 sprintf-related integer and memory overflow issues (Bug#9412).
8702 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8703 (esprintf, exprintf, evxprintf): New functions.
8704 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8705 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8706 (modify_event_symbol): Do not assume that the length of
8707 name_alist_or_stem is safe to alloca and fits in int.
8708 (Fexecute_extended_command): Likewise for function name and binding.
8709 (Frecursion_depth): Wrap around reliably on integer overflow.
8710 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8711 since some callers pass EMACS_INT values.
8712 (Fsingle_key_description): Don't crash if symbol name contains more
8713 than MAX_ALLOCA bytes.
8714 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8715 (get_minibuffer): Arg is now EMACS_INT, not int.
8716 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8717 (esprintf, exprintf, evxprintf): New decls.
8718 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8720 * dbusbind.c (signature_cat): New function.
8721 (xd_signature, Fdbus_register_signal):
8722 Do not overrun buffer; instead, report string overflow.
8724 * dispnew.c (add_window_display_history): Don't overrun buffer.
8725 Truncate instead; this is OK since it's just a log.
8727 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8728 even if the time zone offset is outlandishly large.
8729 Don't mishandle offset == INT_MIN.
8731 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8732 when creating daemon; the previous buffer-overflow check was incorrect.
8734 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8735 which has the guts of the old verror function.
8737 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8738 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8740 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8741 (font_unparse_xlfd): Don't blindly alloca long strings.
8742 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8743 fits in int, when using sprintf. Use single snprintf to count
8744 length of string rather than counting it via multiple sprintfs;
8745 that's simpler and more reliable.
8746 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8747 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8748 sprintf, in case result does not fit in int.
8750 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8751 (fontset_from_font): Print it.
8753 * frame.c (tty_frame_count): Now printmax_t, not int.
8754 (make_terminal_frame, set_term_frame_name): Print it.
8755 (x_report_frame_params): In X, window IDs are unsigned long,
8756 not signed long, so print them as unsigned.
8757 (validate_x_resource_name): Check for implausibly long names,
8758 and don't assume name length fits in 'int'.
8759 (x_get_resource_string): Don't blindly alloca invocation name;
8760 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8763 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8764 (xg_check_special_colors, xg_set_geometry):
8765 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8767 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8768 Use esprintf, not sprintf, in case result does not fit in int.
8770 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8771 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8772 it as a large positive number.
8773 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8774 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8776 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8777 in case result does not fit in int.
8779 * print.c (float_to_string): Detect width overflow more reliably.
8780 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8781 buffer overrun. Don't assume list length fits in 'int'. Treat
8782 print length of 0 as 0, not as infinity; to be consistent with other
8783 uses of print length in this function. Don't overflow print length
8784 index. Don't assume hash table size fits in 'long', or that
8785 vectorlike size fits in 'unsigned long'.
8787 * process.c (make_process): Use printmax_t, not int, to format
8788 process-name gensyms.
8790 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8792 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8793 to avoid potential buffer overrun.
8795 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8796 if X resource line is longer than 512 bytes.
8798 * xfns.c (x_window): Make sprintf buffer a bit bigger
8799 to avoid potential buffer overrun.
8801 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8803 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8805 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8807 Integer overflow fixes for scrolling, etc.
8808 Without these, Emacs silently mishandles large integers sometimes.
8809 For example, "C-u 4294967297 M-x recenter" was treated as if
8810 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8812 * xdisp.c (try_window_id): Check Emacs fixnum range before
8813 converting to 'int'.
8815 * window.c (window_scroll_line_based, Frecenter):
8816 Check that an Emacs fixnum is in range before assigning it to 'int'.
8817 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8818 values converted from Emacs fixnums.
8819 (Frecenter): Don't wrap around a line count if it is out of 'int'
8820 range; instead, treat it as an extreme value.
8821 (Fset_window_configuration, compare_window_configurations):
8822 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8824 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8825 that can exceed INT_MAX. Check that EMACS_INT value is in range
8826 before assigning it to the (possibly-narrower) index.
8827 (match_limit): Don't assume that a fixnum can fit in 'int'.
8829 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8832 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8833 (Fvertical_motion): Don't wrap around LINES values that don't fit
8834 in 'int'. Instead, treat them as extreme values. This is good
8835 enough for windows, which can't have more than INT_MAX lines anyway.
8837 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8839 * Require libxml/parser.h to avoid compilation warning.
8841 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8843 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8844 since this reportedly can destroy thread storage.
8846 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8848 * syntax.c (find_defun_start): Update all cache variables if
8849 exiting early (Bug#9401).
8851 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8853 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8855 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8856 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8857 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8859 * term.c (tty_append_glyph): New function.
8860 (produce_stretch_glyph): Static function and its prototype deleted.
8862 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8865 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8867 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8868 when checking :margin (Bug#9390).
8869 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8870 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8871 so that the name doesn't mislead. All uses changed.
8873 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8875 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8878 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8880 * xdisp.c (move_it_to): Don't bail out early when reaching
8881 position beyond to_charpos, if we are scanning backwards.
8882 (move_it_vertically_backward): When DY == 0, make sure we get to
8883 the first character in the line after the newline.
8885 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8887 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8888 (ccl_driver): Do not generate an out-of-range pointer.
8889 (Fccl_execute_on_string): Remove unnecessary check for
8890 integer overflow, noted by Stefan Monnier in
8891 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8892 Remove a FIXME that didn't need fixing.
8893 Simplify the newly-introduced buffer reallocation code.
8895 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8897 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8899 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8901 Integer and memory overflow issues (Bug#9196).
8903 * doc.c (get_doc_string): Rework so that
8904 get_doc_string_buffer_size is the actual buffer size, rather than
8905 being 1 less than the actual buffer size; this makes xpalloc more
8908 * image.c (x_allocate_bitmap_record, cache_image):
8909 * xselect.c (Fx_register_dnd_atom):
8910 Simplify previous changes by using xpalloc.
8912 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8913 since either will do and ptrdiff_t is convenient with xpalloc.
8915 * charset.c (charset_table_size)
8916 (struct charset_sort_data.priority): Now ptrdiff_t.
8917 (charset_compare): Don't overflow if priorities differ greatly.
8918 (Fsort_charsets): Don't assume list length fits in int.
8919 Check for size-calculation overflow when allocating sort data.
8920 (syms_of_charset): Allocate an initial charset table that is
8921 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8923 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8925 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8926 The actual value is always <= INT_MAX, and leaving it unsigned made
8927 overflow checking harder.
8929 * dispextern.h (struct glyph_matrix.rows_allocated)
8930 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8931 with xpalloc. The values are still always <= INT_MAX.
8933 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8935 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8936 (SAFE_NALLOCA): New macro.
8938 * region-cache.c (struct boundary.pos, find_cache_boundary)
8939 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8940 (set_cache_region, invalidate_region_cache)
8941 (revalidate_region_cache, know_region_cache, region_cache_forward)
8942 (region_cache_backward, pp_cache):
8943 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8944 so that ptrdiff_t * can be passed to xpalloc.
8945 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8946 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8947 (pp_cache): Don't assume cache_len fits in int.
8948 * region-cache.h: Adjust extern decls to match.
8950 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8951 EMACS_INT, since either will do, for xpalloc.
8953 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8954 (xnmalloc, xnrealloc, xpalloc): New functions.
8956 * bidi.c (bidi_shelve_header_size): New constant.
8957 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8958 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8960 * bidi.c (bidi_cache_shrink):
8961 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8963 Don't update size of array until after memory allocation succeeds,
8964 because xmalloc/xrealloc may not return.
8965 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8966 now that we have proper integer overflow checking.
8967 (record_overlay_string, overlay_strings): Catch overflows when
8968 calculating size of overlay_str_buf.
8970 * callproc.c (Fcall_process): Check for size overflow when
8971 calculating size of args2.
8972 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8973 Normally we prefer signed values, but sticking with ptrdiff_t would
8974 require adding more-complicated checks.
8976 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8977 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8978 Redo buffer-overflow calculations to avoid integer overflow.
8979 Add a FIXME comment where memory seems to be over-allocated.
8981 * character.c (Fstring): Check for size-calculation overflow.
8983 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8984 unnecessary integer overflow. Check for size overflow.
8985 (encode_coding_object): Don't update size until xmalloc succeeds.
8987 * composite.c (get_composition_id): Check for overflow in glyph
8988 length calculations.
8990 Integer and memory overflow fixes for display code.
8991 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8992 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8993 (scrolling_window): Check for overflow in size calculations.
8994 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8995 Don't assume glyph table len fits in int.
8996 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8997 (row_table_size): Now ptrdiff_t, not int.
8998 (scrolling_window): Avoid overflow in size calculations.
8999 Don't update size until allocation succeeds.
9000 * fns.c (concat): Check for overflow in size calculations.
9001 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
9002 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
9003 (NEXT_ALMOST_PRIME_LIMIT): New constant.
9005 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
9006 (get_doc_string): Check for size calculation overflow.
9007 Don't update size until allocation succeeds.
9008 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
9009 EMACS_INT, where ptrdiff_t will do.
9010 (Fsubstitute_command_keys): Check for string overflow.
9012 * editfns.c (set_time_zone_rule): Don't assume environment length
9014 (message_length): Now ptrdiff_t, not int.
9015 (Fmessage_box): Don't update size until allocation succeeds.
9016 Don't assume message length fits in int.
9017 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
9019 * emacs.c (main): Do not reallocate argv, since there is a null at
9020 the end that can be overwritten, and this way there's no need to
9021 worry about size-calculation overflow.
9022 (sort_args): Check for size-calculation overflow.
9024 * eval.c (init_eval_once, grow_specpdl): Don't update size until
9026 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
9028 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
9029 (x_set_scroll_bar_width, x_figure_window_size):
9030 Check for integer overflow.
9031 (x_set_alpha): Do not assume XINT fits in int.
9033 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
9034 This is for the members text_lines, text_cols, total_lines, total_cols,
9035 where the system imposes an 'int' limit.
9037 * fringe.c (Fdefine_fringe_bitmap):
9038 Don't update size until alloc works.
9040 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
9041 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
9043 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
9044 Check for size-calculation overflow.
9045 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
9046 do, as we prefer signed integers.
9047 (id_to_widget.max_size, id_to_widget.used)
9048 (xg_store_widget_in_map, xg_remove_widget_from_map)
9049 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
9050 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
9051 Use and return ptrdiff_t, not int.
9052 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
9053 * gtkutil.h: Change prototypes to match the above.
9055 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
9056 are duplicate now that they've been promoted to lisp.h.

9100 (Fset_match_data): Don't assume list lengths fit in 'int'.
9102 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
9103 for command line length. Do not attempt to address one before the

9139 (Fx_change_window_property): Use ptrdiff_t, not int, to count
9140 sizes, since they can exceed INT_MAX in size. Check for size

9144 (xg_select): Check for size calculation overflow.
9145 Don't update size until alloc done.
9147 * xrdb.c (get_environ_db): Don't assume path length fits in int,

9150 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
9151 (X_LONG_MIN): New macros.
9152 Use them to make the following changes clearer.
9153 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
9154 This change doesn't affect the value now, but it may help remind
9155 future maintainers not to raise the value too much later.
9156 (SELECTION_QUANTUM): Remove, replacing with ...
9157 (selection_quantum): ... new function, which avoids overflow.
9159 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

9177 Don't store size until memory allocation succeeds.
9178 (x_get_window_property): Plug memory leak on memory exhaustion.
9179 Don't double-block input; malloc is safe here. Don't assume 2**34
9180 - 4 fits in unsigned long. Add an xassert to check
9181 XGetWindowProperty overflow. Be more careful about overflow
9182 calculations, and distinguish size from memory overflow better.

9188 in the range -65535 through -1 fit in an X unsigned short.
9189 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
9190 result parameters unless successful. Rely on cons_to_unsigned
9191 to report problems with elements; the old code wasn't right anyway.

9226 * lisp.h (hash_lookup, hash_put):
9227 * minibuf.c (Ftest_completion):
9228 Use ptrdiff_t for hash table indexes, not int (which is too
9229 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

9263 (x_send_scroll_bar_event): Likewise. Check that the size does not
9264 exceed limits imposed by XClientMessageEvent, as well as the usual
9265 ptrdiff_t and size_t limits.
9267 * keyboard.c: Overflow, signedness and related fixes.
9268 (make_lispy_movement): Use same integer type in forward decl
9269 that is used in the definition.
9270 (read_key_sequence, keyremap_step):
9271 Change bufsize argument back to int, undoing my 2011-03-30 change.
9272 We prefer signed types, and int is wide enough here.
9273 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
9274 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
9275 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
9276 length, not size_t. Use ptrdiff_t for index, not int.

9306 Prefer int to unsigned where either will do.
9307 (tiff_handler): New function, combining the cores of the
9308 old tiff_error_handler and tiff_warning_handler.
9309 This function is rewritten to use vsnprintf and thereby avoid
9310 stack buffer overflows. It uses only the features of vsnprintf
9311 that are common to both POSIX and native Microsoft.
9312 (tiff_error_handler, tiff_warning_handler): Use it.
9313 (tiff_load, gif_load, imagemagick_load_image):

9317 the integer types that MagickCropImage accepts. Don't assume
9318 Vimagemagick_render_type has a nonnegative value. Don't assume
9319 size_t fits in 'long'.
9320 (gs_load): Use printmax_t to print the widest integers possible.

9338 accurately, and prefer exact match for point under bidi.
9339 Don't advance `row' beyond the last row of the window.
9341 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
9342 into disp_prop; all users changed.
9344 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

9360 positioning on the newline at EOL of R2L text within L2R
9361 paragraph, and vice versa.
9362 (try_cursor_movement): Check continued rows, in addition to
9363 continuation rows. Fixes unwarranted scroll when point enters a
9364 continued line of R2L text within an L2R paragraph, or vice versa.
9365 (cursor_row_p): Consider the case of point being equal to
9366 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
9367 from the end of a short line to the beginning of a continued line
9368 of R2L text within L2R paragraph.

9395 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
9396 instead of CHAR_TO_BYTE. Fixes a crash when a completion
9397 candidate is selected by the mouse, and that candidate has a
9398 composed character under the mouse.
9400 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
9401 coordinates reported by pos-visible-in-window-p for a composed

9416 * image.c (gif_load): Don't assume that each subimage has the same
9417 dimensions as the base image. Handle disposal method that is
9418 "undefined" by the gif spec (Bug#9335).
9420 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
9422 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

9427 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
9428 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
9429 from an Org mode buffer to a Speedbar frame.
9431 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
9432 a composition, take its buffer position from IT->cmp_it.charpos.
9433 Fixes cursor positioning at the beginning of a line that begins
9434 with a composed character.
9436 2011-08-18 Eli Zaretskii <eliz@gnu.org>
9438 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
9439 character bidirectional type, use STRONG_L instead. Fixes crashes
9440 in a buffer produced by `describe-categories'.
9442 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
9443 members before the level stack, so they would be saved and
9444 restored when copying iterator state. Fixes incorrect reordering
9445 around TABs covered by display properties.
9447 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

9522 covered by an image. (Bug#9296)
9524 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
9526 * nsterm.h (ns_run_ascript): Declare.
9527 (NSAPP_DATA2_RUNASSCRIPT): Define.
9529 * nsfns.m (as_script, as_result, as_status): New static variables.
9530 (ns_run_ascript): New function.
9531 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
9532 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
9533 the event loop. Get status from as_status (Bug#7276).
9535 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9536 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9537 the event loop (Bug#7276).
9539 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
9541 * gnutls.c (QCgnutls_bootprop_priority)
9542 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
9543 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
9544 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
9545 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
9546 (QCgnutls_bootprop_verify_hostname_error)
9547 (QCgnutls_bootprop_callbacks_verify): Rename from
9548 Qgnutls_bootprop_..., all uses changed.
9550 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
9553 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
9555 * xfaces.c (Qframe_set_background_mode): Now static.
9556 * dispextern.h (Qframe_set_background_mode): Remove decl.
9558 * process.c (Fnetwork_interface_info): Declare local only if needed.
9560 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
9562 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9563 (Fnetwork_interface_list): Allocate in increments of bytes instead
9564 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9565 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9567 (struct ifflag_def): notrailers is smart on OSX.
9568 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9569 Get hardware address with getifaddrs if available.
9571 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9573 * xdisp.c (iterate_out_of_display_property): xassert that
9574 IT->position is set to within IT->object's boundaries. Break from
9575 the loop as soon as EOB is reached; avoids infloops in redisplay
9576 when IT->position is set up wrongly due to some bug.
9577 Set IT->current to match the bidi iterator unconditionally.
9578 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9579 entry. Force push_it to save on the stack the current
9580 buffer/string position, to be restored by pop_it. Fix flags in
9581 the iterator structure wrt the object coming from a display
9582 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9583 properties. (Bug#9284)
9585 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9587 * fontset.c (fontset_get_font_group): Add proper type checks.
9590 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

9593 and LC_VERSION_MIN_MACOSX.
9594 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9595 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9597 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9599 * xdisp.c (forward_to_next_line_start): Allow to use the
9600 no-display-properties-and-no-overlays under bidi display.
9601 Set disp_pos in the bidi iterator to avoid searches for display
9602 properties and overlays.
9604 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9606 * editfns.c (Fset_time_zone_rule): Document relationship with the
9609 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9610 the font entity extracted from the cache (Bug#8109).
9612 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9614 * composite.c (autocmp_chars): Don't reset point. That is done by
9615 restore_point_unwind (Bug#5984).
9617 2011-08-07 Juri Linkov <juri@jurta.org>
9619 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9620 to show the arg `TIME' instead of `TIMEVAL'.
9622 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9624 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9625 display property strides EOL and includes a newline, as in
9626 longlines-mode. (Bug#9254)
9627 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9628 word-wrap under bidirectional display. (Bug#9224)
9630 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9631 is non-zero, even if the data buffer is NULL. Fixes a crash in
9632 vertical-motion with longlines-mode. (Bug#9254)
9634 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9636 * bidi.c <bidi_cache_total_alloc>: Now static.
9637 (bidi_initialize): Initialize bidi_cache_total_alloc.
9639 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9642 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9643 amount allocated this far in `bidi_cache_total_alloc'.
9644 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9645 non-zero, only free the data buffer without restoring the cache
9646 contents. All callers changed.
9648 * dispextern.h (bidi_unshelve_cache): Update prototype.
9650 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9651 (move_it_in_display_line, move_it_to)
9652 (move_it_vertically_backward, move_it_by_lines): Replace the call
9653 to xfree to an equivalent call to bidi_unshelve_cache.
9654 (move_it_in_display_line_to): Fix logic of returning
9655 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9657 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9659 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9660 came from a string character with a `cursor' property. (Bug#9229)
9662 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9664 * Makefile.in (LIB_PTHREAD): New variable.
9665 (LIBES): Add LIB_PTHREAD (Bug#9216).
9667 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9668 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9670 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9672 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9674 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9676 * xterm.c (x_find_topmost_parent): New function.
9677 (x_set_frame_alpha): Find topmost parent window with
9678 x_find_topmost_parent and set the property there also (bug#9181).
9679 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9681 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9683 * callproc.c (Fcall_process): Avoid vfork clobbering
9684 the local vars buffer, coding_systems, current_dir.
9686 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9688 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9690 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9692 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9693 so that it is not optimized away.
9695 * xdisp.c (compute_display_string_pos): Remove unused local.
9697 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9699 Fix slow cursor motion and scrolling in large buffers with
9700 selective display, like Org Mode buffers. (Bug#9218)
9702 * dispextern.h (struct bidi_it): New member disp_prop_p.
9704 * xdisp.c: Remove one-slot cache of display string positions.
9705 (compute_display_string_pos): Accept an additional argument
9706 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9707 for a display string or property. If found, set DISP_PROP_P
9710 * bidi.c (bidi_fetch_char): Accept an additional argument
9711 DISP_PROP_P, and pass it to compute_display_string_pos.
9712 Only handle text covered by a display string if DISP_PROP_P is returned
9713 non-zero. All callers of bidi_fetch_char changed.
9715 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9717 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9719 2010-12-03 Don March <don@ohspite.net>
9721 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9722 last character M-[char] is translated to ESC [char] (bug#7541).
9724 2011-08-02 Kenichi Handa <handa@m17n.org>
9726 * lisp.h (uniprop_table): Extern it.
9728 * chartab.c (uniprop_table): Make it non-static.
9730 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9732 * xdisp.c (forward_to_next_line_start): Accept additional argument
9733 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9735 (reseat_at_next_visible_line_start): Use the bidi iterator state
9736 returned by forward_to_next_line_start to restore the state of
9737 it->bidi_it after backing up to previous newline. (Bug#9212)
9739 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9741 * regex.c (re_comp): Protoize.
9742 (re_exec): Fix return type.
9743 (regexec): Fix type of `ret'. (Bug#9203)
9745 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9747 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9748 This is needed if max-image-size is a floating-point number.
9750 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9752 * print.c (print_object): Print empty symbol as ##.
9754 * lread.c (read1): Read ## as empty symbol.
9756 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9758 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9759 setting frame foreground color (Bug#9175).
9760 (x_set_background_color): Likewise.
9762 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9763 contents (Bug#9176).
9764 (EmacsTooltip -init): Remove bezels and add shadows to
9767 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9768 or scroll bar (Bug#8470).
9770 * nsfont.m (nsfont_open): Remove assignment to voffset and
9771 unnecessary vars hshink, expand, hd, full_height, min_height.
9772 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9774 * nsterm.h (nsfont_info): Remove voffset field.
9776 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9778 Implement strike-through and overline on NextStep (Bug#8863).
9780 * nsfont.m (nsfont_open): Use underline position provided by font,
9781 instead of hard-coded value of 2.
9782 (nsfont_draw): Call ns_draw_text_decoration instead.
9784 * nsterm.h: Add declaration for ns_draw_text_decoration.
9786 * nsterm.m (ns_draw_text_decoration): New function for drawing
9787 underline, overline, and strike-through.
9788 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9789 ns_draw_text_decoration. Change treatment of cursor drawing to
9790 accommodate underlining, etc.
9792 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9794 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9797 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9799 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9800 Without this fix, if a signal arrives just after memory fills up,
9801 'malloc' might be invoked reentrantly.
9803 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9804 In other words, assume that every image size is allowed, on non-X
9805 hosts. This assumption is probably wrong, but it lets Emacs compile.
9807 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9809 * regex.c (re_iswctype): Convert return values to boolean.
9811 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9813 * xdisp.c (compute_display_string_pos): Don't use cached display
9814 string position if the buffer had its restriction changed.
9817 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9819 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9821 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9823 Integer signedness and overflow and related fixes. (Bug#9079)
9825 * bidi.c: Integer size and overflow fixes.
9826 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9827 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9828 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9829 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9830 (bidi_find_other_level_edge):
9831 Use ptrdiff_t instead of EMACS_INT where either will do.
9832 This works better on 32-bit hosts configured --with-wide-int.
9833 (bidi_cache_ensure_space): Check for size-calculation overflow.
9834 Use % rather than repeated addition, for better worst-case speed.
9835 Don't set bidi_cache_size until after xrealloc returns, because it
9837 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9838 (bidi_cache_ensure_space): Also check that the bidi cache size
9839 does not exceed that of the largest Lisp string or buffer. See Eli
9840 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9842 * alloc.c (__malloc_size_t): Remove.
9843 All uses replaced by size_t. See Andreas Schwab's note
9844 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9846 * image.c: Improve checking for integer overflow.
9847 (check_image_size): Assume that f is nonnull, since
9848 it is always nonnull in practice. This is one less thing to
9849 worry about when checking for integer overflow later.
9850 (x_check_image_size): New function, which checks for integer
9851 overflow issues inside X.
9852 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9853 This removes the need for a memory_full check.
9854 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9855 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9856 (xbm_read_bitmap_data): Change locals back to 'int', since
9857 their values must fit in 'int'.
9858 (xpm_load_image, png_load, tiff_load):
9859 Invoke x_create_x_image_and_pixmap earlier,
9860 to avoid much needless work if the image is too large.
9861 (tiff_load): Treat overly large images as if
9862 x_create_x_image_and_pixmap failed, not as malloc failures.
9863 (gs_load): Use x_check_image_size.
9865 * gtkutil.c: Omit integer casts.
9866 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9867 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9869 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9871 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9872 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9873 would wrongly return t on a 64-bit host.
9875 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9876 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9877 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9878 and therefore cause GCC to emit a bogus diagnostic in some cases.
9880 * image.c: Integer signedness and overflow and related fixes.
9881 This is not an exhaustive set of fixes, but it's time to
9882 record what I've got.
9883 (lookup_pixel_color, check_image_size): Remove redundant decls.
9884 (check_image_size): Don't assume that arbitrary EMACS_INT values
9885 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9886 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9887 (tiff_load, imagemagick_load_image):
9888 Check for overflow in size calculations.
9889 (x_create_x_image_and_pixmap): Remove unnecessary test for
9890 xmalloc returning NULL; that can't happen.
9891 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9892 (xpm_color_bucket): Use better integer hashing function.
9893 (xpm_cache_color): Don't possibly over-allocate memory.
9894 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9895 (gif_memory_source):
9896 Use ptrdiff_t, not int or size_t, to record sizes.
9897 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9898 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9899 either works, as we prefer signed integers.
9900 (tiff_read_from_memory, tiff_write_from_memory):
9901 Return tsize_t, not size_t, since that's what the TIFF API wants.
9902 (tiff_read_from_memory): Don't fail simply because the read would
9903 go past EOF; instead, return a short read.
9904 (tiff_load): Omit no-longer-needed casts.
9905 (Fimagemagick_types): Don't assume size fits into 'int'.
9907 Improve hashing quality when configured --with-wide-int.
9908 * fns.c (hash_string): New function, taken from sxhash_string.
9909 Do not discard information about ASCII character case; this
9910 discarding is no longer needed.
9911 (sxhash-string): Use it. Change sig to match it. Caller changed.
9912 * lisp.h: Declare it.
9913 * lread.c (hash_string): Remove, since we now use fns.c's version.
9914 The fns.c version returns a wider integer if --with-wide-int is
9915 specified, so this should help the quality of the hashing a bit.
9917 * emacs.c: Integer overflow minor fix.
9918 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9919 Define only if GNU_LINUX.
9920 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9922 * dispnew.c: Integer signedness and overflow fixes.
9923 Remove unnecessary forward decls, that were a maintenance hassle.
9924 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9926 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9927 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9928 (prepare_desired_row, line_draw_cost):
9929 Use int, not unsigned, where either works.
9930 (save_current_matrix, restore_current_matrix):
9931 Use ptrdiff_t, not size_t, where either works.
9932 (init_display): Check for overflow more accurately, and without
9933 relying on undefined behavior.
9935 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9936 Remove, replacing with the new symbols in lisp.h. All uses changed.
9937 * fileio.c (make_temp_name):
9938 * filelock.c (lock_file_1, lock_file):
9939 * xdisp.c (message_dolog):
9940 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9941 Use pMd etc. instead.
9942 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9943 replacing the pWIDE etc. symbols removed from editfns.c.
9945 * keyboard.h (num_input_events): Now uintmax_t.
9946 This is (very slightly) less likely to mess up due to wraparound.
9949 * buffer.c: Integer signedness fixes.
9950 (alloc_buffer_text, enlarge_buffer_text):
9951 Use ptrdiff_t rather than size_t when either will do, as we prefer
9954 * alloc.c: Integer signedness and overflow fixes.
9955 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9956 (__malloc_size_t): Default to size_t, not to int.
9957 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9958 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9959 Prefer ptrdiff_t to size_t when either would do, as we prefer
9961 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9962 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9963 Now const. Initialize with values that are in range even if char
9965 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9966 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9967 These functions do the right thing with sizes > 2**32.
9968 (check_depth): Now ptrdiff_t, not int.
9969 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9970 Adjust to new way of storing sizes. Check for size overflow bugs
9972 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9973 slightly wrong anyway, as it missed one instance of
9974 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9975 (refill_memory_reserve): Omit needless cast to size_t.
9976 (mark_object_loop_halt): Mark as externally visible.
9978 * xselect.c: Integer signedness and overflow fixes.
9979 (Fx_register_dnd_atom, x_handle_dnd_message):
9980 Use ptrdiff_t, not size_t, since we prefer signed.
9981 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9982 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9983 x_dnd_atoms_size and x_dnd_atoms_length.
9985 * doprnt.c: Prefer signed to unsigned when either works.
9987 * doprnt.c (doprnt):
9989 * xdisp.c (vmessage):
9990 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9991 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9992 prefer signed arithmetic to avoid comparison confusion.
9993 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9994 but is a bit tricky.
9996 Assume freestanding C89 headers, string.h, stdlib.h.
9997 * data.c, doprnt.c, floatfns.c, print.c:
9998 Include float.h unconditionally.
9999 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
10000 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
10001 * regex.c: Likewise for stddef.h, string.h.
10002 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
10003 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
10004 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
10005 (STDC_HEADERS): Remove obsolete defines.
10006 * sysdep.c: Include limits.h unconditionally.
10008 Assume support for memcmp, memcpy, memmove, memset.
10009 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
10010 * regex.c (memcmp, memcpy):
10011 Remove; we assume C89 now.
10013 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
10014 (__malloc_safe_bcopy): Remove; no longer needed.
10016 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
10017 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
10018 well either way, and we prefer signed to unsigned.
10020 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
10022 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
10023 closes the connection while we're reading (bug#9182).
10025 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
10027 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
10028 are specified (Bug#9168).
10030 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
10032 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
10033 Found by GCC static checking and --with-wide-int on a 32-bit host.
10035 2011-07-25 Eli Zaretskii <eliz@gnu.org>
10037 * xdisp.c (compute_display_string_pos): Fix logic of caching
10038 previous display string position. Initialize cached_prev_pos to
10039 -1. Fixes slow-down at the beginning of a buffer.
10041 2011-07-24 Eli Zaretskii <eliz@gnu.org>
10043 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
10044 for attrs[LFACE_FONTSET_INDEX].
10046 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
10048 * xml.c (parse_region): Remove unused local
10049 that was recently introduced.
10051 2011-07-23 Eli Zaretskii <eliz@gnu.org>
10053 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
10054 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
10056 * xdisp.c (move_it_in_display_line_to): Record the best matching
10057 position for TO_CHARPOS while scanning the line, and restore it on
10058 exit if none of the characters scanned was an exact match.
10059 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
10060 when exact match is impossible due to invisible text, and the
10061 lines are truncated.
10063 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
10065 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
10068 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10070 Fix a significant slow-down of cursor motion with C-n, C-p,
10071 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
10072 auto-repeat under bidi redisplay in fontified buffers.
10073 * xdisp.c (compute_stop_pos_backwards): New function.
10074 (next_element_from_buffer): Call compute_stop_pos_backwards to
10075 find a suitable prev_stop when we find ourselves before
10077 (reseat): Don't look for prev_stop, as that could mean a very long
10079 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
10080 <cached_disp_overlay_modiff>: Cache for last found display string
10082 (compute_display_string_pos): Return the cached position if asked
10083 about the same buffer in the same area of character positions, and
10084 the buffer wasn't changed since the time the display string
10085 position was cached.
10087 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10089 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
10090 is an integer, which is important for empty lines. (Bug#9149)
10092 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
10094 * frame.c (Fmodify_frame_parameters): In tty case, update the
10095 default face if necessary (Bug#4238).
10097 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
10099 * editfns.c (Fstring_to_char): No need to explain what a character
10100 is in the docstring (Bug#6576).
10102 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10104 * xml.c (parse_region): Make sure we always return a tree.
10106 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
10108 * xml.c (parse_region): If a document contains only comments,
10111 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10113 * xml.c (make_dom): Return comments, too.
10115 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
10118 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
10119 and the surrounding thread.
10120 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
10121 rather than fgets, and retry after EINTR. Otherwise, 'emacs
10122 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
10124 * s/openbsd.h (BROKEN_SIGIO): Define.
10125 * unexelf.c (unexec) [__OpenBSD__]:
10126 Don't update the .mdebug section of the Alpha COFF symbol table.
10128 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10130 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
10133 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
10135 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
10136 This fixes some race conditions on the permissions of any newly
10139 * alloc.c (valid_pointer_p): Use pipe, not open.
10140 This fixes some permissions issues when debugging.
10142 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
10143 If fchown fails to set both uid and gid, try to set just gid,
10144 as that is sometimes allowed. Adjust the file's mode to eliminate
10145 setuid or setgid bits that are inappropriate if fchown fails.
10147 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
10149 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
10150 to compare Lisp_Objects.
10151 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
10152 global_gnutls_log_level, don't mistake it for a Lisp_Object.
10153 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
10155 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
10157 * lread.c (read_integer): Unread even EOF character.
10158 (read1): Likewise. Properly record start position of symbol.
10160 * lread.c (read1): Read `#:' as empty uninterned symbol if no
10161 symbol character follows.
10163 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
10165 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
10166 This works around a problem with the previous change to Fcopy_file.
10167 Recent glibc declares fchown with __attribute__((warn_unused_result)),
10168 and without this change, GCC might complain about discarding
10169 fchown's return value.
10171 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
10173 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
10175 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
10177 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
10179 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
10181 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
10182 it's used from the C level.
10184 * process.c: Use the same condition for POLL_FOR_INPUT in both
10185 keyboard.c and process.c (bug#1858).
10187 2011-07-09 Lawrence Mitchell <wence@gmx.li>
10189 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
10190 (Fgnutls_boot): Use it.
10192 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
10194 * doc.c (Fsubstitute_command_keys): Revert last change.
10196 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
10198 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
10199 quotes the next character, and doesn't affect other longer
10200 sequences (bug#8935).
10202 * lread.c (syms_of_lread): Clarify that is isn't only
10203 `eval-buffer' and `eval-defun' that's affected by
10204 `lexical-binding' (bug#8460).
10206 2011-07-15 Eli Zaretskii <eliz@gnu.org>
10208 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
10209 bidi redisplay when a line includes both an image and is truncated.
10211 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
10213 Fix minor problems found by static checking.
10214 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
10215 (elsz): Now a signed constant, not a size_t var. We prefer signed
10216 types to unsigned, to avoid integer comparison confusion. Without
10217 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
10218 "cannot optimize loop, the loop counter may overflow", a symptom
10220 * indent.c (Fvertical_motion): Mark locals as initialized.
10221 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
10223 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
10225 * search.c (Fre_search_backward): Mention `case-fold-search' in
10226 all the re_search_* functions (bug#8138).
10228 * keyboard.c (Fopen_dribble_file): Document when the file is

10239 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
10240 (reseat_to_string): Initialize bidi_it->string.s and
10241 bidi_it->string.schars.
10242 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
10243 NULL (avoids a crash in bidi_paragraph_init).
10244 Initialize itb.string.lstring.
10245 (init_iterator): Call bidi_init_it only of a valid
10246 buffer position was specified. Initialize paragraph_embedding to
10248 (reseat_to_string): Initialize the bidi iterator.
10249 (display_string): If we need to ignore text properties of
10250 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
10251 original value of -1 will not work with bidi.)
10252 (compute_display_string_pos): First arg is now struct
10253 `text_pos *'; all callers changed. Support display properties on
10255 (compute_display_string_end): Support display properties on Lisp
10257 (init_iterator, reseat_1, reseat_to_string): Initialize the
10258 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
10259 when iterating on a string not from display properties).
10260 (compute_display_string_pos, compute_display_string_end):
10261 Fix calculation of the object to scan. Fixes an error when using
10263 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
10264 base_level_stop; instead, set base_level_stop to BEGV.
10265 Fixes crashes in vertical-motion.
10266 (next_element_from_buffer): Improve commentary for when
10267 the iterator is before prev_stop.
10268 (init_iterator): Initialize bidi_p from the default value of
10269 bidi-display-reordering, not from buffer-local value. Use the
10270 buffer-local value only if initializing for buffer iteration.
10271 (handle_invisible_prop): Support invisible properties on strings
10272 that are being bidi-reordered.
10273 (set_iterator_to_next): Support bidi reordering of C strings and
10275 (next_element_from_string): Support bidi reordering of Lisp
10277 (handle_stop_backwards): Support Lisp strings as well.
10278 (display_string): Support display of R2L glyph rows.
10279 Use IT_STRING_CHARPOS when displaying from a Lisp string.
10280 (init_iterator): Don't initialize it->bidi_p for strings
10282 (reseat_to_string): Initialize it->bidi_p for strings here.
10283 (next_element_from_string, next_element_from_c_string)
10284 (next_element_from_buffer): Add xassert's for correspondence
10285 between IT's object being iterated and it->bidi_it.string

10288 (next_element_from_c_string): Handle the case of the first string
10289 character that is not the first one in the visual order.
10290 (get_visually_first_element): New function, refactored from common
10291 parts of next_element_from_buffer, next_element_from_string, and
10292 next_element_from_c_string.
10293 (tool_bar_lines_needed, redisplay_tool_bar)
10294 (display_menu_bar): Force left-to-right direction. Add a FIXME
10295 comment for making that be controlled by a user option.
10296 (push_it, pop_it): Save and restore the state of the
10297 bidi iterator. Save and restore the bidi_p flag.
10298 (pop_it): Iterate out of display property for string iteration as
10300 (iterate_out_of_display_property): Support iteration over strings.
10301 (handle_single_display_spec): Set up it->bidi_it for iteration
10302 over a display string, and call bidi_init_it.
10303 (handle_single_display_spec, next_overlay_string)
10304 (get_overlay_strings_1, push_display_prop): Set up the bidi
10305 iterator for displaying display or overlay strings.
10306 (forward_to_next_line_start): Don't use the shortcut if
10308 (back_to_previous_visible_line_start): If handle_display_prop
10309 pushed the iterator stack, restore the internal state of the bidi
10310 iterator by calling bidi_pop_it same number of times.
10311 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
10312 and we are bidi-iterating, don't decrement the iterator position;
10313 instead, set the first_elt flag in the bidi iterator, to produce
10315 (reseat_1): Remove redundant setting of string_from_display_prop_p.
10316 (push_display_prop): xassert that we are iterating a buffer.
10317 (push_it, pop_it): Save and restore paragraph_embedding member.
10318 (handle_single_display_spec, next_overlay_string)
10319 (get_overlay_strings_1, reseat_1, reseat_to_string)
10320 (push_display_prop): Set up the `unibyte' member of bidi_it.string
10321 correctly. Don't assume unibyte strings are not bidi-reordered.
10322 (compute_display_string_pos)
10323 (compute_display_string_end): Fix handling the case of C string.
10324 (push_it, pop_it): Save and restore from_disp_prop_p.

10329 popping after iteration over a string that came from a display
10330 property. Fix a typo in popping stretch info. Add an assertion
10331 for verifying that the iterator position is in sync with the bidi
10333 (handle_single_display_spec, get_overlay_strings_1)
10334 (push_display_prop): Fix initialization of paragraph direction for
10335 string when that of the parent object is not yet determined.

10337 iterator with IT's position. (Bug#7616)
10338 (find_row_edges): If ROW->start.pos gives position
10339 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
10340 (handle_stop, back_to_previous_visible_line_start, reseat_1):
10341 Reset the from_disp_prop_p flag.
10342 (SAVE_IT, RESTORE_IT): New macros.

10346 (move_it_to, move_it_vertically_backward, move_it_by_lines)
10347 (try_scrolling, redisplay_window, display_line): Use them when
10348 saving a temporary copy of the iterator and restoring it back.
10349 (back_to_previous_visible_line_start, reseat_1)
10350 (init_iterator): Empty the bidi cache "stack".
10351 (move_it_in_display_line_to): If iterator ended up at
10352 EOL, but we never saw any buffer positions smaller than
10353 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
10354 motion in bidi-reordered lines.
10355 (move_it_in_display_line_to): Record prev_method and prev_pos
10356 immediately before the call to set_iterator_to_next. Fixes cursor
10357 motion in bidi-reordered lines with stretch glyphs and strings
10358 displayed in margins. (Bug#8133) (Bug#8867)
10359 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
10361 (pos_visible_p): Support positions in bidi-reordered lines.
10362 Save and restore bidi cache.
10364 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
10365 (bidi_paragraph_info): Delete unused struct.
10366 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
10367 (bidi_cache_start): New variable.
10368 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

10376 (bidi_fetch_char): Accept new argument STRING; all callers
10377 changed. Support iteration over a string. Support strings with
10378 display properties. Support unibyte strings. Fix the type of
10379 `len' according to what STRING_CHAR_AND_LENGTH expects.

10381 (bidi_resolve_explicit, bidi_resolve_weak)
10382 (bidi_level_of_next_char, bidi_move_to_visually_next):
10383 Support iteration over a string.
10384 (bidi_set_sor_type, bidi_resolve_explicit_1)
10385 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
10386 can now be zero (for strings); special values 0 and -1 were
10387 changed to -1 and -2, respectively.
10388 (bidi_char_at_pos): New function.
10389 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
10390 Call it instead of FETCH_MULTIBYTE_CHAR.

10400 (bidi_initialize): Initialize the bidi cache start stack pointer.
10401 (bidi_cache_ensure_space): New function, refactored from part of

10405 (bidi_count_bytes, bidi_char_at_pos): New functions.
10406 (bidi_cache_search): Don't assume bidi_cache_last_idx is

10475 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
10477 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
10478 The old code sometimes used this field without initializing it.
10480 * alloc.c (gc_sweep): Don't read past end of array.
10481 In theory, the old code could also have corrupted Emacs internals,
10482 though it'd be very unlikely.

10486 * character.c (Fcharacterp): Don't advertise optional ignored

10586 sigprocmask is portable only for single-threaded applications, and
10587 Emacs can be multi-threaded when it uses GTK.

10745 (clone_per_buffer_values): Don't assume that

10747 This isn't true in general, and it's particularly not true
10748 if Emacs is configured with --with-wide-int.
10749 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

10786 Random fixes. E.g., (random) never returned negative values.
10787 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10788 subseconds part to the entropy, as that's a bit more random.
10789 Prefer signed to unsigned, since the signedness doesn't matter and
10790 in general we prefer signed. When given a limit, use a
10791 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10792 latter isn't right if USE_2_TAGS_FOR_INTS.
10793 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10794 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10804 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
10806 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
10807 This is more efficient than Ffile_directory_p and avoids a minor race.
10809 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
10811 * buffer.c (Foverlay_put): Say what the return value is
10814 * fileio.c (barf_or_query_if_file_exists): Check first if the file
10815 is a directory before asking whether to use the file name
10817 (barf_or_query_if_file_exists): Make the "File is a directory"
10818 error be more correct.
10820 * fns.c (Frequire): Remove the mention of the .gz files, since
10821 that's installation-specific, but keep the mention of
10822 `get-load-suffixes'.

10826 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

10834 Qgnutls_bootprop_verify_error (which is no longer used).
10836 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
10837 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10838 Also (re)move comments that are misplaced or no longer relevant.
10840 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10842 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

10856 No need to define when HAVE_GSETTINGS || !HAVE_XFT.
10858 * keymap.c (access_keymap_1): Now static.
10860 2011-07-02 Chong Yidong <cyd@stupidchicken.com>

10939 * eval.c (struct backtrace): Simplify and port the data structure.
10940 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10941 signed bit field, as this assumption is not portable and it makes
10942 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10943 "char debug_on_exit : 1" as this is not portable either; instead,
10944 use the portable "unsigned int debug_on_exit : 1". Remove unused
10945 member evalargs. Remove obsolete comments about cc bombing out.

11135 (read1): Check for integer overflow in radices, and in
11136 read-circle numbers.
11137 (read_escape): Avoid int overflow.
11138 (Fload, openp, read_buffer_size, read1)
11139 (substitute_object_recurse, read_vector, read_list, map_obarray):

11162 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
11163 The following patches are for when GLYPH_DEBUG && !XASSERT.

11180 on undefined behavior with wrong number of arguments.
11181 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
11182 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
11183 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
11184 since we're not interested in debugging glyphs with old libraries.
11185 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
11186 GCC 4.6.0's static checking.

11228 (x_session_initialize): Do not assume string length fits in int.
11230 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

11276 Don't assume pid_t and time_t fit in unsigned long.
11277 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
11278 (current_lock_owner): Prefer signed type for sizes.
11279 Use memcpy, not strncpy, where memcpy is what is really wanted.
11280 Don't assume (via atoi) that time_t and pid_t fit in int.
11281 Check for time_t and/or pid_t out of range, e.g., via a network share.
11282 Don't alloca where an auto var works fine.

11301 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
11302 (main): Don't invoke strlen when not needed.
11304 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
11305 (XD_DEBUG_MESSAGE): Don't waste a byte.
11307 * callproc.c (getenv_internal_1, getenv_internal)
11308 (Fgetenv_internal):
11309 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
11311 * lread.c (invalid_syntax): Omit length argument.
11312 All uses changed. This doesn't fix a bug, but it simplifies the
11313 code away from its former Hollerith-constant appearance, and it's
11314 one less 'int' to worry about when looking at integer-overflow issues.
11315 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
11317 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
11318 This didn't break anything, but it didn't help either.
11319 It's confusing to put a bogus integer in a place where the actual
11320 value does not matter.
11321 (LIST_END_P): Remove unused macro and its bogus comment.
11322 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
11324 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
11325 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
11327 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
11328 We prefer signed types, and the value cannot exceed the EMACS_INT
11329 range anyway (because otherwise the length would not be representable).
11330 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
11331 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
11332 This avoids a GCC warning when WIDE_EMACS_INT.
11334 * indent.c (sane_tab_width): New function.
11335 (current_column, scan_for_column, Findent_to, position_indentation)
11336 (compute_motion): Use it. This is just for clarity.
11337 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
11339 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
11341 * lisp.h (lint_assume): New macro.
11342 * composite.c (composition_gstring_put_cache):
11343 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
11345 * editfns.c, insdel.c:
11346 Omit unnecessary forward decls, to simplify future changes.
11348 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
11350 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
11352 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
11353 Use much-faster test for byte-length change.
11354 Don't assume string byte-length fits in 'int'.
11355 Check that character arg fits in 'int'.
11356 (mapcar1): Declare byte as byte, for clarity.
11358 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
11360 * fns.c (concat): Catch string overflow earlier.
11361 Do not rely on integer wraparound.
11363 * dispextern.h (struct it.overlay_strings_charpos)
11364 (struct it.selective): Now EMACS_INT, not int.
11365 * xdisp.c (forward_to_next_line_start)
11366 (back_to_previous_visible_line_start)
11367 (reseat_at_next_visible_line_start, next_element_from_buffer):
11368 Don't arbitrarily truncate the value of 'selective' to int.
11370 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
11372 * composite.c: Don't truncate sizes to 'int'.
11373 (composition_gstring_p, composition_reseat_it)
11374 (composition_adjust_point): Use EMACS_INT, not int.
11375 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
11376 not EMACS_UINT, for indexes.
11378 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
11380 * buffer.c: Include <verify.h>.
11381 (struct sortvec.priority, struct sortstr.priority):
11382 Now EMACS_INT, not int.
11383 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
11384 (struct sortstr.size, record_overlay_string)
11385 (struct sortstrlist.size, struct sortlist.used):
11386 Don't truncate size to int.
11387 (record_overlay_string): Check for size-calculation overflow.
11388 (init_buffer_once): Check at compile-time, not run-time.
11390 2011-06-22 Jim Meyering <meyering@redhat.com>
11392 Don't leak an XBM-image-sized buffer
11393 * image.c (xbm_load): Free the image buffer after using it.
11395 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
11398 * composite.c (find_automatic_composition): Omit needless 'return 0;'
11399 that Sun C diagnosed.
11400 * fns.c (secure_hash): Fix pointer signedness issue.
11401 * intervals.c (static_offset_intervals): New function.
11402 (offset_intervals): Use it.
11404 2011-06-21 Leo Liu <sdl.web@gmail.com>
11407 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
11410 * fns.c (secure_hash): Rename from crypto_hash_function and change
11411 the first arg to accept symbols.
11412 (Fsecure_hash): New primitive.
11413 (syms_of_fns): New symbols.
11415 2011-06-20 Deniz Dogan <deniz@dogan.se>
11417 * process.c (Fset_process_buffer): Clarify return value in
11420 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
11422 * dispnew.c (add_window_display_history): Use BVAR.
11424 * xdisp.c (debug_method_add): Use BVAR.
11425 (check_window_end, dump_glyph_matrix, dump_glyph)
11426 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
11428 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
11431 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
11432 check till after the cache is created in init_frame_faces.
11434 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
11436 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
11438 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
11440 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
11441 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
11442 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
11444 Improve buffer-overflow checking (Bug#8873).
11445 * fileio.c (Finsert_file_contents):
11446 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
11447 Remove the old (too-loose) buffer overflow checks.
11448 They weren't needed, since make_gap checks for buffer overflow.
11449 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
11450 The old code merely checked for Emacs fixnum overflow, and relied
11451 on undefined (wraparound) behavior. The new code avoids undefined
11452 behavior, and also checks for ptrdiff_t and/or size_t overflow.
11454 * editfns.c (Finsert_char): Don't dump core with very negative counts.
11455 Tune. Don't use wider integers than needed. Don't use alloca.
11456 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
11458 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
11460 * insdel.c, lisp.h (buffer_overflow): New function.
11461 (insert_from_buffer_1, replace_range, replace_range_2):
11462 * insdel.c (make_gap_larger):
11463 * editfns.c (Finsert_char):
11464 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11466 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11468 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11470 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11472 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11473 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11475 * fileio.c: Don't assume EMACS_INT fits in off_t.
11476 (emacs_lseek): New static function.
11477 (Finsert_file_contents, Fwrite_region): Use it.
11478 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11480 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11482 * fns.c: Don't overflow int when computing a list length.
11483 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11484 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11485 truncation on 64-bit hosts. Check for QUIT every
11486 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
11487 faster and is responsive enough.
11488 (Flength): Report an error instead of overflowing an integer.
11489 (Fsafe_length): Return a float if the value is not representable
11490 as a fixnum. This shouldn't happen except in contrived situations.
11491 (Fnthcdr, Fsort): Don't assume list length fits in int.
11492 (Fcopy_sequence): Don't assume vector length fits in int.
11494 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11495 (header_size, word_size): New constants.
11496 (allocate_vectorlike): Don't check size overflow here.
11497 (allocate_vector): Check it here instead, since this is the only
11498 caller of allocate_vectorlike that could cause overflow.
11499 Check that the new vector's length is representable as a fixnum.
11501 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11502 The previous code was bogus. For example, next_almost_prime (32)
11503 returned 39, which is undesirable as it is a multiple of 3; and
11504 next_almost_prime (24) returned 25, which is a multiple of 5 so
11505 why was the code bothering to check for multiples of 7?
11507 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11509 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11511 Variadic C functions now count arguments with ptrdiff_t.
11512 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11513 Back then I didn't know that the Emacs coding style prefers signed int.
11514 Also, in the meantime I found a few more instances where arguments
11515 were being counted with int, which may truncate counts on 64-bit
11516 machines, or EMACS_INT, which may be unnecessarily wide.
11517 * lisp.h (struct Lisp_Subr.function.aMANY)
11518 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11519 Arg counts are now ptrdiff_t, not size_t.
11520 All variadic functions and their callers changed accordingly.
11521 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11522 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11523 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11524 * callint.c (Fcall_interactively): Check arg count for overflow,
11525 to avoid potential buffer overrun. Use signed char, not 'int',
11526 for 'varies' array, so that we needn't bother to check its size
11527 calculation for overflow.
11528 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11529 * eval.c (apply_lambda):
11530 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11531 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11532 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11534 * callint.c (Fcall_interactively): Don't use index var as event count.
11536 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11537 * mem-limits.h (SIZE): Remove; no longer used.
11539 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11541 Remove unnecessary casts.
11542 * xterm.c (x_term_init):
11543 * xfns.c (x_set_border_pixel):
11544 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11545 These aren't needed now that we assume ANSI C.
11547 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11548 It's more likely to cause problems (due to unsigned overflow)
11551 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11553 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11555 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11557 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11559 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11561 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11563 GLYPH_CODE_FACE returns EMACS_INT, not int.
11564 * dispextern.h (merge_faces):
11565 * xfaces.c (merge_faces):
11566 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11567 Don't assume EMACS_INT fits in int.
11569 * character.h (CHAR_VALID_P): Remove unused parameter.
11570 * fontset.c, lisp.h, xdisp.c: All uses changed.
11572 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11574 * fns.c (concat): Minor tuning based on overflow analysis.
11575 This doesn't fix any bugs. Use int to hold character, instead
11576 of constantly refetching from Emacs object. Use XFASTINT, not
11577 XINT, for value known to be a character. Don't bother comparing
11578 a single byte to 0400, as it's always less.
11580 * floatfns.c (Fexpt):
11581 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11583 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11586 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11588 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11589 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11590 incorrectly succeed when S was a string, because 4294967386 was
11591 truncated before it was used.
11593 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11594 Otherwise, an out-of-range integer could cause undefined behavior
11597 * composite.c: Use int, not EMACS_INT, for characters.
11598 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11599 EMACS_INT, for values that are known to be in character range.
11600 This doesn't fix any bugs but is the usual style inside Emacs and
11601 may generate better code on 32-bit machines.
11603 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11604 This is for reasons similar to the recent CHAR_STRING fix.
11605 * charset.c (Fencode_char): Check that character arg is actually
11606 a character. Pass an int to ENCODE_CHAR.
11607 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11608 wider than 'int', as a compile-time check to prevent future regressions
11611 * character.c (char_string): Remove unnecessary casts.
11613 Make sure a 64-bit char is never passed to CHAR_STRING.
11614 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11615 by silently ignoring the top 32 bits, allowing some values
11616 that were far too large to be valid characters.
11617 * character.h: Include <verify.h>.
11618 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11619 arguments are no wider than unsigned, as a compile-time check
11620 to prevent future regressions in this area.
11622 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11623 (Fsubst_char_in_region):
11625 * xdisp.c (decode_mode_spec_coding):
11626 Adjust to CHAR_STRING's new requirement.
11627 * editfns.c (Finsert_char, Fsubst_char_in_region):
11628 * fns.c (concat): Check that character args are actually
11629 characters. Without this test, these functions did the wrong
11630 thing with wildly out-of-range values on 64-bit hosts.
11632 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11633 These casts should not be needed on 32-bit hosts, either.
11634 * keyboard.c (read_char):
11635 * lread.c (Fload): Remove casts to unsigned.
11637 * lisp.h (UNSIGNED_CMP): New macro.
11638 This fixes comparison bugs on 64-bit hosts.
11639 (ASCII_CHAR_P): Use it.
11640 * casefiddle.c (casify_object):
11641 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11642 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11643 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11644 * dispextern.h (FACE_FROM_ID):
11645 * keyboard.c (read_char): Use UNSIGNED_CMP.
11647 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11648 not to EMACS_INT, to avoid GCC warning.
11650 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11652 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11653 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11654 isn't needed on 32-bit machines.
11656 * buffer.c (Fgenerate_new_buffer_name):
11657 Use EMACS_INT for count, not int.
11658 (advance_to_char_boundary): Return EMACS_INT, not int.
11660 * data.c (Qcompiled_function): Now static.
11662 * window.c (window_body_lines): Now static.
11664 * image.c (gif_load): Rename local to avoid shadowing.
11666 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11667 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11668 * alloc.c (make_save_value): Integer argument is now of type
11669 ptrdiff_t, not int.
11670 (mark_object): Use ptrdiff_t, not int.
11671 * lisp.h (pD): New macro.
11672 * print.c (print_object): Use it.
11674 * alloc.c: Use EMACS_INT, not int, to count objects.
11675 (total_conses, total_markers, total_symbols, total_vector_size)
11676 (total_free_conses, total_free_markers, total_free_symbols)
11677 (total_free_floats, total_floats, total_free_intervals)
11678 (total_intervals, total_strings, total_free_strings):
11679 Now EMACS_INT, not int. All uses changed.
11680 (Fgarbage_collect): Compute overall total using a double, so that
11681 integer overflow is less likely to be a problem. Check for overflow
11682 when converting back to an integer.
11683 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11684 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11685 These were 'int' variables that could overflow on 64-bit hosts;
11686 they were never used, so remove them instead of repairing them.
11687 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11688 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11689 Previously, this ceilinged at INT_MAX, but that doesn't work on
11691 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11693 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11694 (allocate_vectorlike): Check for ptrdiff_t overflow.
11695 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11696 when a (possibly-narrower) signed value would do just as well.
11697 We prefer using signed arithmetic, to avoid comparison confusion.
11699 * alloc.c: Catch some string size overflows that we were missing.
11700 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11701 for convenience in STRING_BYTES_MAX.
11702 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11703 The definition here is exact; the one in lisp.h was approximate.
11704 (allocate_string_data): Check for string overflow. This catches
11705 some instances we weren't catching before. Also, it catches
11706 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11707 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11708 and ptrdiff_t and EMACS_INT are both 64 bits.
11710 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11711 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
11712 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
11714 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
11716 * alloc.c (Fmake_string): Check for out-of-range init.
11718 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
11720 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
11722 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
11724 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
11725 xg_get_default_scrollbar_width.
11727 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
11728 (int_gtk_range_get_value): Move to the scroll bar part of the file.
11729 (style_changed_cb): Call update_theme_scrollbar_width and call
11730 x_set_scroll_bar_default_width and xg_frame_set_char_size for
11731 all frames (Bug#8505).
11732 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
11733 Call gtk_window_set_resizable if HAVE_GTK3.
11734 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
11735 and height if HAVE_GTK3 (Bug#8505).
11736 (scroll_bar_width_for_theme): New variable.
11737 (update_theme_scrollbar_width): New function.
11738 (xg_get_default_scrollbar_width): Move code to

12189 (Fframe_root_window, Fframe_selected_window)
12190 (Fset_frame_selected_window): Move to window.c.

12208 (Fwindow_minibuffer_p): Move up in code and simplify.
12209 (Fset_frame_selected_window): Move here from frame.c.
12211 (Fselected_window, select_window, Fselect_window): Move up in
12212 code. Minor doc-string fixes.
12214 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
12216 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
12217 Do not assume that spare memory exists; that assumption is valid
12218 only if SYSTEM_MALLOC.
12219 (LARGE_REQUEST): New macro, so that the issue of large requests
12220 is separated from the issue of spare memory.
12222 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
12224 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

12250 New error handlers.
12251 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
12252 Obey Vx_select_enable_clipboard_manager. Catch errors in
12253 x_clipboard_manager_save (Bug#8779).
12254 (Vx_select_enable_clipboard_manager): New variable.
12255 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
12257 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
12259 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
12261 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12263 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap

12270 2011-06-03 Eli Zaretskii <eliz@gnu.org>
12272 Support bidi reordering of text covered by display properties.
12274 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
12275 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
12276 (bidi_cache_search, bidi_cache_iterator_state)
12277 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12278 (bidi_level_of_next_char, bidi_move_to_visually_next):
12279 Support character positions inside a run of characters covered by a
12281 (bidi_paragraph_init, bidi_resolve_explicit_1)
12282 (bidi_level_of_next_char): Call bidi_fetch_char and
12283 bidi_fetch_char_advance instead of FETCH_CHAR and
12284 FETCH_CHAR_ADVANCE.
12285 (bidi_init_it): Initialize new members.
12286 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
12288 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
12289 instead of using explicit *_CHAR codes.
12290 (bidi_resolve_explicit, bidi_resolve_weak):
12291 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
12292 bidirectional text is supported only in multibyte buffers.
12293 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
12294 it to initialize the frame_window_p member of struct bidi_it.
12295 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
12296 (bidi_resolve_explicit, bidi_resolve_weak)

12298 bidi_it->nchars is non-positive.
12299 (bidi_level_of_next_char): Don't try to lookup the cache for the
12300 next/previous character if nothing is cached there yet, or if we
12301 were just reseat()'ed to a new position.
12303 * xdisp.c (set_cursor_from_row): Set start and stop points
12304 according to the row's direction when priming the loop that looks
12305 for the glyph on which to display cursor.
12306 (single_display_spec_intangible_p): Function deleted.
12307 (display_prop_intangible_p): Reimplement to call
12308 handle_display_spec instead of single_display_spec_intangible_p.
12309 Accept 3 additional arguments needed by handle_display_spec.
12310 This fixes incorrect cursor motion across display property with complex
12311 values: lists, `(when COND...)' forms, etc.
12312 (single_display_spec_string_p): Support property values that are
12313 lists with the argument STRING its top-level element.
12314 (display_prop_string_p): Fix the condition for processing a
12315 property that is a list to be consistent with handle_display_spec.
12316 (handle_display_spec): New function, refactored from the
12317 last portion of handle_display_prop.
12318 (compute_display_string_pos): Accept additional argument
12319 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
12320 value of a `display' property is a "replacing spec".
12321 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
12322 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
12323 the display property, but just return a value indicating whether
12324 the display property will replace the characters it covers.
12325 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
12326 frame_window_p members of struct bidi_it.
12327 (compute_display_string_pos, compute_display_string_end):
12329 (push_it): Accept second argument POSITION, where pop_it should
12330 jump to continue iteration.
12331 (reseat_1): Initialize bidi_it.disp_pos.
12333 * keyboard.c (adjust_point_for_property): Adjust the call to
12334 display_prop_intangible_p to its new signature.
12336 * dispextern.h (struct bidi_it): New member frame_window_p.
12337 (bidi_init_it): Update prototypes.
12338 (display_prop_intangible_p): Update prototype.
12339 (compute_display_string_pos, compute_display_string_end):
12340 Declare prototypes.
12341 (struct bidi_it): New members nchars and disp_pos. ch_len is now
12344 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
12346 Malloc failure behavior now depends on size of allocation.
12347 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
12348 * lisp.h: Change signatures accordingly.
12349 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
12350 All callers changed. (Bug#8762)
12352 * gnutls.c: Use Emacs's memory allocators.
12353 Without this change, the gnutls library would invoke malloc etc.
12354 directly, which causes problems on non-SYNC_INPUT hosts, and which
12355 runs afoul of improving memory_full behavior. (Bug#8761)
12356 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
12357 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
12358 xfree instead of the default malloc, realloc, free.
12359 (Fgnutls_boot): No need to check for memory allocation failure,
12360 since xmalloc does that for us.
12362 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
12363 * category.c (hash_get_category_set):
12364 * ccl.c (ccl_driver):
12365 * charset.c (Fdefine_charset_internal):
12366 * charset.h (struct charset.hash_index):

12368 (composition_gstring_put_cache):
12369 * composite.h (struct composition.hash_index):
12370 * dispextern.h (struct image.hash):
12371 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
12372 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
12373 (hashfn_equal, hashfn_user_defined, make_hash_table)

12375 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
12376 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
12377 (Fsxhash, Fgethash, Fputhash, Fmaphash):
12378 * image.c (make_image, search_image_cache, lookup_image)
12379 (xpm_put_color_table_h):
12380 * lisp.h (struct Lisp_Hash_Table):
12381 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
12382 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
12383 for hashes and hash indexes, instead of 'unsigned' and 'int'.
12384 * alloc.c (allocate_vectorlike):
12385 Check for overflow in vector size calculations.
12386 * ccl.c (ccl_driver):
12387 Check for overflow when converting EMACS_INT to int.
12388 * fns.c, image.c: Remove unnecessary static decls that would otherwise
12389 need to be updated by these changes.
12390 * fns.c (make_hash_table, maybe_resize_hash_table):
12391 Check for integer overflow with large hash tables.
12392 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
12393 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
12394 (SXHASH_REDUCE): New macro.
12395 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
12396 Use it instead of discarding useful hash info with large hash values.
12397 (sxhash_float): New function.
12398 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
12399 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
12400 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
12401 Rewrite to use FIXNUM_BITS, as this simplifies things.
12402 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
12403 Adjust signatures to match updated version of code.
12404 (consing_since_gc): Now EMACS_INT, since a single hash table can
12405 use more than INT_MAX bytes.
12407 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
12409 Make it possible to build with GCC-4.6+ -O2 -flto.
12411 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
12413 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
12415 * minibuf.c (get_minibuffer, read_minibuf_unwind):
12416 Call minibuffer-inactive-mode.
12418 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
12420 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
12421 Update dependencies.
12423 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12425 * data.c (init_data): Remove code for UTS, this system is not
12428 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12430 Don't force ./temacs to start in terminal mode.
12432 * frame.c (make_initial_frame): Initialize faces in all cases, not
12433 only when CANNOT_DUMP is defined.
12434 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
12436 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12438 * dispnew.c (add_window_display_history): Use const for the string
12439 pointer. Remove declaration, not needed.
12441 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12443 Use 'inline', not 'INLINE'.
12444 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
12445 * alloc.c, fontset.c (INLINE): Remove.
12446 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
12447 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
12448 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
12449 * gmalloc.c (register_heapinfo): Use inline unconditionally.
12450 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
12452 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12454 Make it possible to run ./temacs.
12456 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
12457 syms_of_callproc does the same thing. Remove test for
12458 "initialized", do it in the caller.
12459 * emacs.c (main): Avoid calling set_initial_environment when dumping.
12461 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
12463 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
12464 (read_minibuf): Use get_minibuffer.
12465 (syms_of_minibuf): Use DEFSYM.
12466 (Qmetadata): New var.
12467 * data.c (Qbuffer): Don't make it static.
12468 (syms_of_data): Use DEFSYM.
12470 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12472 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
12473 (CCL_CODE_MIN): New macro.
12475 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
12477 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
12479 * eval.c (Qdebug): Now static.
12480 * lisp.h (Qdebug): Remove decl. This reverts a part of the
12481 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
12482 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
12484 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12486 * image.c: Various fixes to ImageMagick code comments.
12487 (Fimagemagick_types): Doc fix.
12489 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12491 Minor fixes prompted by GCC 4.6.0 warnings.
12493 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12495 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12496 (x_clipboard_manager_save_all): Move extern decl to ...
12497 * xterm.h: ... here, so that it can be checked for consistency.
12499 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12501 * xselect.c (x_clipboard_manager_save_frame)
12502 (x_clipboard_manager_save_all): New functions.
12503 (Fx_clipboard_manager_save): Lisp function deleted.
12505 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12506 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12508 * xterm.h: Update prototype.
12510 2011-05-28 William Xu <william.xwl@gmail.com>
12512 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12513 exiting (Bug#8239).
12515 2011-05-28 Jim Meyering <meyering@redhat.com>
12517 Avoid a sign-extension bug in crypto_hash_function.
12518 * fns.c (to_uchar): Define.
12519 (crypto_hash_function): Use it to convert some newly-signed
12520 variables to unsigned, to avoid sign-extension bugs. For example,
12521 without this change, (md5 "truc") would evaluate to
12522 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12523 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12524 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12526 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12528 Integer overflow fixes.
12530 * dbusbind.c: Serial number integer overflow fixes.
12531 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12532 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12533 to hold a serial number that is too large for a fixnum.
12534 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12535 Check for serial numbers out of range. Decode any serial number
12536 that was so large that it became a float. (Bug#8722)
12538 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12539 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12540 Use XFASTINT rather than XUINT when numbers are nonnegative.
12541 (xd_append_arg, Fdbus_method_return_internal):
12542 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12543 arguments, check that Lisp number is nonnegative, rather than
12544 silently wrapping negative numbers around. (Bug#8722)
12545 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12548 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12550 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12552 ccl: Add integer overflow checks.
12553 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12554 (IN_INT_RANGE): New macros.
12555 (ccl_driver): Use them to check for integer overflow when
12556 decoding a CCL program. Many of the new checks are whether XINT (x)
12557 fits in int; it doesn't always, on 64-bit hosts. The new version
12558 doesn't catch all possible integer overflows, but it's an
12559 improvement. (Bug#8719)
12561 * alloc.c (make_event_array): Use XINT, not XUINT.
12562 There's no need for unsigned here.
12564 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12565 This follows up to the 2011-05-06 change that substituted uintptr_t
12566 for EMACS_INT. This case wasn't caught back then.
12568 Rework Fformat to avoid integer overflow issues.
12569 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12570 now (part of C89). Include <verify.h>.
12571 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12572 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12573 (Fformat): Avoid the prepass trying to compute sizes; it was only
12574 approximate and thus did not catch overflow reliably. Instead, walk
12575 through the format just once, formatting and computing sizes as we go,
12576 checking for integer overflow at every step, and allocating a larger
12577 buffer as needed. Keep track separately whether the format is
12578 multibyte. Keep only the most-recently calculated precision, rather
12579 than them all. Record whether each argument has been converted to
12580 string. Use EMACS_INT, not int, for byte and char and arg counts.
12581 Support field widths and precisions larger than INT_MAX. Avoid
12582 sprintf's undefined behavior with conversion specifications such as %#d
12583 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12584 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12585 formatting out-of-range floating point numbers with int
12586 formats. (Bug#8668)
12588 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12590 * data.c: Avoid integer truncation in expressions involving floats.
12591 * data.c: Include <intprops.h>.
12592 (arith_driver): When there's an integer overflow in an expression
12593 involving floating point, convert the integers to floating point
12594 so that the resulting value does not suffer from catastrophic
12595 integer truncation. For example, on a 64-bit host (* 4
12596 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12597 Do not rely on undefined behavior after integer overflow.
12599 merge count_size_as_multibyte, parse_str_to_multibyte
12600 * character.c, character.h (count_size_as_multibyte):
12601 Rename from parse_str_to_multibyte; all uses changed.
12602 Check for integer overflow.
12603 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12604 since it's now a duplicate of the other. This is more of
12605 a character than a buffer op, so better that it's in character.c.
12606 * fns.c, print.c: Adjust to above changes.
12608 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12610 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.

12614 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12615 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12616 (x_clipboard_manager_save): Now static.
12617 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12619 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12620 (crypto_hash_function): Now static.
12621 Fix pointer signedness problems. Avoid unnecessary initializations.
12623 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12625 * termhooks.h (Vselection_alist): Make it terminal-local.
12627 * terminal.c (create_terminal): Initialize it.
12629 * xselect.c: Support for clipboard managers.
12630 (Vselection_alist): Move to termhooks.h as terminal-local var.
12631 (LOCAL_SELECTION): New macro.
12632 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12633 (symbol_to_x_atom): Remove gratuitous arg.
12634 (x_handle_selection_request, lisp_data_to_selection_data)
12635 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12636 (x_own_selection, x_get_local_selection, x_convert_selection):
12637 New arg, specifying work frame. Use terminal-local Vselection_alist.
12638 (some_frame_on_display): Delete unused function.
12639 (Fx_own_selection_internal, Fx_get_selection_internal)
12640 (Fx_disown_selection_internal, Fx_selection_owner_p)
12641 (Fx_selection_exists_p): New optional frame arg.
12642 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12643 (x_handle_selection_clear): Don't treat other terminals with the
12644 same keyboard specially. Use the terminal-local Vselection_alist.
12645 (x_clear_frame_selections): Use Frun_hook_with_args.
12647 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12649 * xterm.h: Add support for those atoms.
12651 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12653 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12654 (converted_selections, conversion_fail_tag): New global variables.
12655 (x_selection_request_lisp_error): Free the above.
12656 (x_get_local_selection): Remove unnecessary code.
12657 (x_reply_selection_request): Args changed; handle arbitrary array
12658 of converted selections stored in converted_selections.
12659 Separate the XChangeProperty and SelectionNotify steps.
12660 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12661 (x_convert_selection): New function.
12662 (x_handle_selection_event): Simplify.
12663 (x_get_foreign_selection): Don't ignore incoming requests while
12664 waiting for an answer; this will fail when we implement
12665 SAVE_TARGETS, and seems unnecessary anyway.
12666 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12667 (Vx_sent_selection_functions): Doc fix.
12669 2011-05-26 Leo Liu <sdl.web@gmail.com>
12671 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12673 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12675 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12677 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12678 for fringe update if it has periodic bitmap.
12679 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12680 and fringe_bitmap_periodic_p.
12682 * fringe.c (get_fringe_bitmap_data): New function.
12683 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12684 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12685 row. Mark glyph row for fringe update if periodicity changed.
12687 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12688 for fringe update unless it has periodic bitmap.
12690 2011-05-25 Kenichi Handa <handa@m17n.org>
12692 * xdisp.c (get_next_display_element): Set correct it->face_id for
12693 a static composition.
12695 2011-05-24 Leo Liu <sdl.web@gmail.com>
12698 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12700 * fns.c (crypto_hash_function, Fsha1): New function.
12701 (Fmd5): Use crypto_hash_function.
12702 (syms_of_fns): Add Ssha1.
12704 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12706 * gnutls.c: Remove unused macros.
12707 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12708 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12709 Remove macros that are defined and never used.
12710 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12712 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12714 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12715 (Fx_get_selection_internal): Minor cleanup.
12716 (Fx_own_selection_internal): Rename arguments for consistency with
12719 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12721 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12723 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12725 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12727 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12729 * dispnew.c (scrolling_window): Don't exclude the case that the
12730 last enabled row in the desired matrix touches the bottom boundary.
12732 2011-05-21 Glenn Morris <rgm@gnu.org>
12734 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12735 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12736 and add some more files.
12738 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12740 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12741 report_file_error introduced by the change from 2011-05-07.
12743 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12745 * systime.h (Time): Define only if emacs is defined.
12746 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12747 where the include path doesn't have X11/X.h by default. See
12748 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12750 2011-05-20 Kenichi Handa <handa@m17n.org>
12752 * composite.c (find_automatic_composition): Fix previous change.
12754 2011-05-20 Glenn Morris <rgm@gnu.org>
12756 * lisp.mk: New file, split from Makefile.in.
12757 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12758 (shortlisp): Remove.
12759 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12761 2011-05-19 Glenn Morris <rgm@gnu.org>
12763 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12764 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12765 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12766 (lisp): Set the order to that of loadup.el.
12767 (shortlisp): Make it a copy of $lisp.
12768 (SOME_MACHINE_LISP): Remove.
12769 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12770 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12772 2011-05-18 Kenichi Handa <handa@m17n.org>
12774 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12775 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12776 (find_automatic_composition): Mostly rewrite for efficiency.
12778 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12780 * makefile.w32-in: Update dependencies.
12782 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12784 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12785 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12787 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12789 Fix some integer overflow issues, such as string length overflow.
12791 * insdel.c (count_size_as_multibyte): Check for string overflow.
12793 * character.c (lisp_string_width): Check for string overflow.
12794 Use EMACS_INT, not int, for string indexes and lengths; in
12795 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12796 the resulting string length overflows an EMACS_INT; instead,
12797 report a string overflow if no precision given. When checking for
12798 precision exhaustion, use a check that cannot possibly have
12799 integer overflow. (Bug#8675)
12800 * character.h (lisp_string_width): Adjust to new signature.
12802 * alloc.c (string_overflow): New function.
12803 (Fmake_string): Use it. This doesn't change behavior, but saves
12804 a few bytes and will simplify future changes.
12805 * character.c (string_escape_byte8): Likewise.
12806 * lisp.h (string_overflow): New decl.
12808 Fixups, following up to the user-interface timestamp change.
12809 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12810 for UI timestamps, instead of unsigned long.
12811 * msdos.c (mouse_get_pos): Likewise.
12812 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12813 * w32gui.h (Time): Define by including "systime.h" rather than by
12814 declaring it ourselves. (Bug#8664)
12816 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12817 * image.c (clear_image_cache): Likewise.
12819 * term.c (term_mouse_position): Don't assume time_t wraparound.
12821 Be more systematic about user-interface timestamps.
12822 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12823 and sometimes 'EMACS_UINT', to represent these timestamps.
12824 This change causes it to use 'Time' uniformly, as that's what X uses.
12825 This makes the code easier to follow, and makes it easier to catch
12826 integer overflow bugs such as Bug#8664.
12827 * frame.c (Fmouse_position, Fmouse_pixel_position):
12828 Use Time, not unsigned long, for user-interface timestamps.
12829 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12830 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12831 * keyboard.h (last_event_timestamp): Likewise.
12832 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12833 * menu.h (xmenu_show): Likewise.
12834 * term.c (term_mouse_position): Likewise.
12835 * termhooks.h (struct input_event.timestamp): Likewise.
12836 (struct terminal.mouse_position_hook): Likewise.
12837 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12838 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12839 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12840 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12841 what it was before.
12842 * menu.h, termhooks.h: Include "systime.h", for Time.
12844 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12845 Don't assume that the difference between two unsigned long values
12846 can fit into an integer. At this point, we know button_down_time
12847 <= event->timestamp, so the difference must be nonnegative, so
12848 there's no need to cast the result if double-click-time is
12849 nonnegative, as it should be; check that it's nonnegative, just in
12850 case. This bug is triggered when events are more than 2**31 ms
12851 apart (about 25 days). (Bug#8664)
12853 * xselect.c (last_event_timestamp): Remove duplicate decl.
12854 (x_own_selection): Remove needless cast to unsigned long.
12856 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12857 that always fit in int. Use a sentinel instead of a counter, to
12858 avoid a temp and to allay GCC's concerns about possible int overflow.
12859 * frame.h (struct frame): Use int for menu_bar_items_used
12860 instead of EMACS_INT, since it always fits in int.
12862 * menu.c (grow_menu_items): Check for int overflow.
12864 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12866 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12867 Before, the code was not consistent. These values cannot exceed
12868 2**31 - 1 so there's no need to make them unsigned.
12869 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12870 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12871 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12873 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12875 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12876 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12877 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12878 presumably because the widths might not match.
12880 * window.c (size_window): Avoid needless test at loop start.
12882 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12884 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12886 2011-05-12 Drew Adams <drew.adams@oracle.com>
12888 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12890 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12892 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12893 `width' to `bar_area_x' and `bar_area_width', respectively.
12894 (x_scroll_run): Take account of fringe background extension.
12896 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12897 Rename local vars `left' and `width' to `bar_area_x' and
12898 `bar_area_width', respectively.
12899 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12900 background extension.
12902 2011-05-10 Jim Meyering <meyering@redhat.com>
12904 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12906 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12908 * image.c (Finit_image_library): Return t for built-in image types,
12909 like pbm and xbm. (Bug#8640)
12911 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12913 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12915 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12917 * w32console.c (Fset_screen_color): Doc fix.
12918 (Fget_screen_color): New function.
12919 (syms_of_ntterm): Defsubr it.
12921 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12922 unlink the temporary file if Fcall_process didn't create it in the
12924 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12925 child process will be redirected to a file specified with `:file'.
12926 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12927 cue to call_process_cleanup not to close that handle.
12929 2011-05-07 Ben Key <bkey76@gmail.com>
12931 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12932 one of two shell specific rules, either bootstrap-temacs-CMD or
12933 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12934 to the previous implementation of the bootstrap-temacs rule.
12935 The bootstrap-temacs-CMD rule is similar to the previous
12936 implementation of the bootstrap-temacs rule except that it
12937 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12940 These changes, along with some changes to nt/configure.bat,
12941 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12942 earlier fix to add support for --cflags and --ldflags options
12943 that include quotes so that it works whether make uses cmd or
12946 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12948 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12949 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12951 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12952 a string. Handle both cases.
12953 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12954 (Fdbus_register_method): Use Qinvalid_function.
12956 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12958 * makefile.w32-in: Update dependencies.
12959 (LISP_H): Add inttypes.h and stdin.h.
12960 (PROCESS_H): Add unistd.h.
12962 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12964 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12965 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12967 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12969 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12971 * term.c (vfatal): Remove stray call to va_end.
12972 It's not needed and the C Standard doesn't allow it here anyway.
12974 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12975 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12977 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12980 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12982 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12984 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12986 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12988 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12990 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12991 * charset.c (Fdefine_charset_internal): Don't initialize
12992 charset.code_space[15]. The value was garbage, on hosts with
12993 32-bit int (Bug#8600).
12995 * lread.c (read_integer): Be more consistent with string-to-number.
12996 Use string_to_number to do the actual conversion; this avoids
12997 rounding errors and fixes some other screwups. Without this fix,
12998 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12999 (digit_to_number): Move earlier, for benefit of read_integer.
13000 Return -1 if the digit is out of range for the base, -2 if it is
13001 not a digit in any supported base. (Bug#8602)
13003 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
13005 * dispnew.c (scrolling_window): Return 1 if we scrolled,
13006 to match comment at start of function. This also removes a
13007 GCC warning about overflow in a 32+64-bit port.
13009 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
13011 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
13012 Reported by Stefan Monnier in
13013 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
13014 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13015 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
13017 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
13018 (EMACS_UINTPTR): Likewise, with uintptr_t.
13020 * lisp.h: Prefer 64-bit EMACS_INT if available.
13021 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
13022 on 32-bit hosts that have 64-bit int, so that they can access
13024 However, temporarily disable this change unless the temporary
13025 symbol WIDE_EMACS_INT is defined.
13027 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
13029 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
13030 This removes an assumption that EMACS_INT and long are the same
13031 width as pointers. The assumption is true for Emacs porting targets
13032 now, but we want to make other targets possible.
13033 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
13034 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
13035 In the rest of the code, change types of integers that hold casted
13036 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
13037 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
13038 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
13039 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
13040 No need to cast type when ORing.
13041 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
13042 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
13043 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
13044 assume EMACS_INT is the same width as char *.
13045 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
13046 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
13047 Remove no-longer-needed casts.
13048 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
13049 (xg_tool_bar_help_callback, xg_make_tool_item):
13050 Use EMACS_INTPTR to hold an integer
13051 that will be cast to void *; this can avoid a GCC warning
13052 if EMACS_INT is not the same width as void *.
13053 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
13054 * xdisp.c (display_echo_area_1, resize_mini_window_1):
13055 (current_message_1, set_message_1):
13056 Use a local to convert to proper width without a cast.
13057 * xmenu.c (dialog_selection_callback): Likewise.
13059 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
13060 Also, don't assume VALBITS / RAND_BITS is less than 5,
13061 and don't rely on undefined behavior when shifting a 1 left into
13063 * lisp.h (get_random): Change signature to match.
13065 * lread.c (hash_string): Use size_t, not int, for hash computation.
13066 Normally we prefer signed values; but hashing is special, because
13067 it's better to use unsigned division on hash table sizes so that
13068 the remainder is nonnegative. Also, size_t is the natural width
13069 for hashing into memory. The previous code used 'int', which doesn't
13070 retain enough info to hash well into very large tables.
13071 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
13073 * dbusbind.c: Don't possibly lose pointer info when converting.
13074 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13075 Use XPNTR rather than XHASH, so that the high-order bits of
13076 the pointer aren't lost when converting through void *.
13078 * eval.c (Fautoload): Don't double-shift a pointer.
13080 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

13113 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
13114 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
13115 Remove unused parameter `fildes'.
13116 * process.c (read_process_output, send_process): Don't pass it.
13118 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
13120 Fix previous change: the library cache is defined in w32.c.
13121 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
13122 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

13164 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
13165 instead of gnutls_record_check_pending.
13167 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
13169 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
13171 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
13172 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists

13177 * xterm.c (x_set_frame_alpha): Do not set property on anything

13212 (Fcall_process_region): Ditto.
13214 2011-04-30 Eli Zaretskii <eliz@gnu.org>
13216 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
13217 rather than `XVECTOR (FOO)->size'.
13219 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
13220 inttypes.h, as a gnulib replacement is used if it not available in
13223 2011-04-21 Eli Zaretskii <eliz@gnu.org>
13225 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
13226 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
13227 of MOST_POSITIVE_FIXNUM. (Bug#8528)
13229 * coding.c (coding_alloc_by_realloc): Error out if destination
13230 will grow beyond MOST_POSITIVE_FIXNUM.
13231 (decode_coding_emacs_mule): Abort if there isn't enough place in
13232 charbuf for the composition carryover bytes. Reserve an extra

13287 Improve `doprnt' and its usage. (Bug#8545)
13288 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
13289 `format_end'. Remove support for %l as a conversion specifier.
13290 Don't use xrealloc. Improve diagnostics when the %l size modifier
13291 is used. Update the commentary.
13293 * eval.c (verror): Simplify calculation of size_t.
13295 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
13298 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
13300 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
13303 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
13305 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
13306 This makes this file independent of the recent pseudovector change.
13308 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
13310 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
13312 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
13313 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
13314 Remove unused local.
13315 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
13317 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
13318 GCC 4.6.0 optimizes based on type-based alias analysis.
13319 For example, if b is of type struct buffer * and v of type struct
13320 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
13321 != &v->size, and therefore "v->size = 1; b->size = 2; return
13322 v->size;" must therefore return 1. This assumption is incorrect
13323 for Emacs, since it type-puns struct Lisp_Vector * with many other
13324 types. To fix this problem, this patch adds a new type struct
13325 vectorlike_header that documents the constraints on layout of vectors
13326 and pseudovectors, and helps optimizing compilers not get fooled
13327 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
13328 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
13329 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
13331 (XSETPVECTYPE): Rewrite in terms of new macro.
13332 (XSETPVECTYPESIZE): New macro, specifying both type and size.
13333 This is a bit clearer, and further avoids the possibility of
13334 undesirable aliasing.
13335 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
13336 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
13337 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
13338 since Lisp_Subr is a special case (no "next" field).
13339 (ASIZE): Now uses header.size rather than size.
13340 All previous uses of XVECTOR (foo)->size replaced to use this macro,
13341 to avoid the hassle of writing XVECTOR (foo)->header.size.
13342 (struct vectorlike_header): New type.
13343 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
13344 object, to help avoid aliasing.
13345 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
13346 (SUBRP): Likewise, since Lisp_Subr is a special case.
13347 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
13348 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
13349 (struct Lisp_Hash_Table): Combine first two members into a single
13350 struct vectorlike_header member. All uses of "size" and "next" members
13351 changed to be "header.size" and "header.next".
13352 * buffer.h (struct buffer): Likewise.
13353 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
13354 * frame.h (struct frame): Likewise.
13355 * process.h (struct Lisp_Process): Likewise.
13356 * termhooks.h (struct terminal): Likewise.
13357 * window.c (struct save_window_data, struct saved_window): Likewise.
13358 * window.h (struct window): Likewise.
13359 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
13360 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
13361 * buffer.c (init_buffer_once): Likewise.
13362 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
13364 * process.c (Fformat_network_address): Use local var for size,
13367 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
13369 Make the Lisp reader and string-to-float more consistent (Bug#8525)
13370 * data.c (atof): Remove decl; no longer used or needed.
13371 (digit_to_number): Move to lread.c.
13372 (Fstring_to_number): Use new string_to_number function, to be
13373 consistent with how the Lisp reader treats infinities and NaNs.
13374 Do not assume that floating-point numbers represent EMACS_INT
13375 without losing information; this is not true on most 64-bit hosts.
13376 Avoid double-rounding errors, by insisting on integers when
13377 parsing non-base-10 numbers, as the documentation specifies.
13378 * lisp.h (string_to_number): New decl, replacing ...
13379 (isfloat_string): Remove.
13380 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
13381 (read1): Do not accept +. and -. as integers; this
13382 appears to have been a coding error. Similarly, do not accept
13383 strings like +-1e0 as floating point numbers. Do not report
13384 overflow for integer overflows unless the base is not 10 which
13385 means we have no simple and reliable way to continue.
13386 Break out the floating-point parsing into a new
13387 function string_to_number, so that Fstring_to_number parses
13388 floating point numbers consistently with the Lisp reader.
13389 (digit_to_number): Move here from data.c. Make it static inline.
13390 (E_CHAR, EXP_INT): Remove, replacing with ...
13391 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
13392 (string_to_number): New function, replacing isfloat_string.
13393 This function checks for valid syntax and produces the resulting
13394 Lisp float number too. Rework it so that string-to-number
13395 no longer mishandles examples like "1.0e+". Use strtoumax,
13396 so that overflow for non-base-10 numbers is reported only when
13397 there's no portable and simple way to convert to floating point.
13399 * textprop.c (set_text_properties_1): Rewrite for clarity,
13400 and to avoid GCC warning about integer overflow.
13402 * intervals.h (struct interval): Use EMACS_INT for members
13403 where EMACS_UINT might cause problems. See
13404 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
13405 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
13406 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
13408 (offset_intervals): Tell GCC not to worry about length overflow
13409 when negating a negative length.
13411 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
13412 (overrun_check_free): Likewise.
13414 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
13415 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
13418 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13419 (gnutls_make_error): Rename local to avoid shadowing.
13420 (gnutls_emacs_global_deinit): ifdef out; not used.
13421 (Fgnutls_boot): Use const for pointer to readonly storage.
13422 Comment out unused local. Fix pointer signedness problems.
13424 * lread.c (openp): Don't stuff size_t into an 'int'.
13425 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
13426 about possible signed overflow.
13428 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13429 (GDK_KEY_g): Don't define if already defined.
13430 (xg_prepare_tooltip): Avoid pointer signedness problem.
13431 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
13433 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
13434 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
13436 * xfns.c (Fx_window_property): Simplify a bit,
13437 to make a bit faster and to avoid GCC 4.6.0 warning.
13438 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
13440 * fns.c (internal_equal): Don't assume size_t fits in int.
13442 * alloc.c (compact_small_strings): Tighten assertion a little.
13444 Replace pEd with more-general pI, and fix some printf arg casts.
13445 * lisp.h (pI): New macro, generalizing old pEd macro to other
13446 conversion specifiers. For example, use "...%"pI"d..." rather
13447 than "...%"pEd"...".
13448 (pEd): Remove. All uses replaced with similar uses of pI.
13449 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
13450 * alloc.c (check_pure_size): Don't overflow by converting size to int.
13451 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
13452 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
13453 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
13454 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
13455 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
13457 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
13458 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
13459 * print.c (safe_debug_print, print_object): Likewise.
13460 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
13462 Use pI instead of if-then-else-abort. Use %p to avoid casts,
13463 avoiding the 0 flag, which is not portable.
13464 * process.c (Fmake_network_process): Use pI to avoid cast.
13465 * region-cache.c (pp_cache): Likewise.
13466 * xdisp.c (decode_mode_spec): Likewise.
13467 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13468 behavior on 64-bit hosts with printf arg.
13469 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
13470 (x_stop_queuing_selection_requests): Likewise.
13471 (x_get_window_property): Don't truncate byte count to an 'int'
13474 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13475 here, since it parses constructs like leading '-' and spaces,
13476 which are not wanted; and it overflows with large numbers.
13477 Instead, simply match F[0-9]+, which is what is wanted anyway.
13479 * alloc.c: Remove unportable assumptions about struct layout.
13480 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13481 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13482 (allocate_vectorlike, make_pure_vector): Use the new macros,
13483 plus offsetof, to remove unportable assumptions about struct layout.
13484 These assumptions hold on all porting targets that I know of, but
13485 they are not guaranteed, they're easy to remove, and removing them
13486 makes further changes easier.
13488 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13489 This doesn't fix a bug but makes the code clearer.
13490 (string_overrun_cookie): Now const. Use initializers that
13491 don't formally overflow signed char, to avoid warnings.
13492 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
13493 can cause Emacs to crash when string overrun checking is enabled.
13494 (allocate_buffer): Don't assume sizeof (struct buffer) is a
13495 multiple of sizeof (EMACS_INT); it need not be, if
13496 alignof(EMACS_INT) < sizeof (EMACS_INT).
13497 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

13506 supposed to be handshaking. (Bug#8556)
13507 Reported by Paul Eggert <eggert@cs.ucla.edu>.

13528 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
13529 "cast to pointer from integer of different size".
13531 Improve doprnt and its use in verror. (Bug#8545)
13532 * doprnt.c (doprnt): Document the set of format control sequences
13533 supported by the function. Use SAFE_ALLOCA instead of always
13536 * eval.c (verror): Don't limit the buffer size at size_max-1, that
13537 is one byte too soon. Don't use xrealloc; instead xfree and
13540 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
13542 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

13549 docstring. Start callback support.
13550 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
13551 unless a fatal error occurred. Call gnutls_alert_send_appropriate

13612 changes in globals.h immediately force recompilation.
13613 (TAGS): Depend on $(CURDIR)/m/intel386.h and
13614 $(CURDIR)/s/ms-w32.h.

13649 * callint.c (Fcall_interactively): When displaying error message
13650 about invalid control letter, pass the character's codepoint, not
13651 a pointer to its multibyte form. Improve display of the character
13652 in octal and display also its hex code.
13654 * character.c (char_string): Use %x to display the (unsigned)
13655 codepoint of an invalid character, to avoid displaying a bogus
13658 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
13659 `error', not SYMBOL_NAME itself.
13661 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
13662 character arguments to `error'.
13664 * charset.c (check_iso_charset_parameter): Fix incorrect argument
13665 to `error' in error message about FINAL_CHAR argument. Make sure
13666 FINAL_CHAR is a character, and use %c when it is passed as
13667 argument to `error'.
13669 2011-04-23 Eli Zaretskii <eliz@gnu.org>
13671 * s/ms-w32.h (localtime): Redirect to sys_localtime.
13673 * w32.c: Include <time.h>.

13733 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
13734 by pacifying GCC about it. Maybe it's time to retire it?
13735 * xfaces.c (USG, __TIMEVAL__): Likewise.
13737 * dispextern.h (struct redisplay_interface): Rename param
13738 to avoid shadowing.
13739 * termhooks.h (struct terminal): Likewise.

13856 * nsfont.m: Fixed bugs in ns_get_family and
13857 ns_descriptor_to_entity that were caused by using free to
13858 deallocate memory blocks that were allocated by xmalloc (via
13859 xstrdup). This caused Emacs to crash when compiled with
13860 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
13861 --enable-checking=xmallocoverrun). xfree is now used to
13862 deallocate these memory blocks.

13876 (emacs_read, emacs_write): Remove check for negative size, as the
13877 Emacs source code has been audited now.
13878 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
13879 (emacs_read, emacs_write): Use it.
13880 * process.c (send_process): Adjust to the new signatures of
13881 emacs_write and emacs_gnutls_write. Do not attempt to store
13882 a byte offset into an 'int'; it might overflow.
13883 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

14350 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
14351 since callers should never pass a negative size.
14352 Change the signature to match that of plain 'read' and 'write'; see
14353 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
14354 * lisp.h: Update prototypes of emacs_write and emacs_read.
14356 2011-04-11 Eli Zaretskii <eliz@gnu.org>
14358 * xdisp.c (redisplay_window): Don't try to determine the character
14359 position of the scroll margin if the window start point w->startp
14360 is outside the buffer's accessible region. (Bug#8468)
14362 2011-04-10 Eli Zaretskii <eliz@gnu.org>
14364 Fix write-region and its subroutines for buffers > 2GB.
14365 * fileio.c (a_write, e_write): Modify declaration of arguments and
14366 local variables to support buffers larger than 2GB.
14367 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
14369 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
14370 argument, local variables, and return value.
14372 * lisp.h: Update prototypes of emacs_write and emacs_read.
14374 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
14376 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
14378 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
14380 Fix more problems found by GCC 4.6.0's static checks.
14382 * xdisp.c (vmessage): Use a better test for character truncation.
14384 * charset.c (load_charset_map): <, not <=, for optimization,
14385 and to avoid potential problems with integer overflow.
14386 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
14387 * casetab.c (set_identity, shuffle): Likewise.
14388 * editfns.c (Fformat): Likewise.
14389 * syntax.c (skip_chars): Likewise.
14391 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
14392 This also lets GCC 4.6.0 generate slightly better loop code.
14394 * callint.c (Fcall_interactively): <, not <=, for optimization.
14395 (Fcall_interactively): Count the number of arguments produced,
14396 not the number of arguments given. This is simpler and lets GCC
14397 4.6.0 generate slightly better code.
14399 * ftfont.c: Distingish more carefully between FcChar8 and char.
14400 The previous code passed unsigned char * to a functions like
14401 strlen and xstrcasecmp that expect char *, which does not
14402 conform to the C standard.
14403 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
14404 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
14405 char * when the C standard requires it.
14407 * keyboard.c (read_char): Remove unused var.
14409 * eval.c: Port to Windows vsnprintf (Bug#8435).
14410 Include <limits.h>.
14411 (SIZE_MAX): Define if the headers do not.
14412 (verror): Do not give up if vsnprintf returns a negative count.
14413 Instead, grow the buffer. This ports to Windows vsnprintf, which
14414 does not conform to C99. Problem reported by Eli Zaretskii.
14415 Also, simplify the allocation scheme, by avoiding the need for
14416 calling realloc, and removing the ALLOCATED variable.
14418 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
14420 Remove invocations of doprnt, as Emacs now uses vsnprintf.
14421 But keep the doprint source code for now, as we might revamp it
14422 and use it again (Bug#8435).
14423 * lisp.h (doprnt): Remove.
14424 * Makefile.in (base_obj): Remove doprnt.o.
14425 * deps.mk (doprnt.o): Remove.
14427 error: Print 32- and 64-bit integers portably (Bug#8435).
14428 Without this change, on typical 64-bit hosts error ("...%d...", N)
14429 was used to print both 32- and 64-bit integers N, which relied on
14430 undefined behavior.
14431 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
14432 * lisp.h (error, verror): Mark as printf-like functions.
14433 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
14434 Report overflow in size calculations when allocating printf buffer.
14435 Do not truncate output string at its first null byte.
14436 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
14437 Truncate the output at a character boundary, since vsnprintf does not
14439 * charset.c (check_iso_charset_parameter): Convert internal
14440 character to string before calling 'error', since %c now has the
14442 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
14443 overflow when computing char to be passed to 'error'. Do not
14444 pass Lisp_Object to 'error'; pass the integer instead.
14445 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
14446 formatted with plain %d.
14448 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
14450 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
14452 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
14454 * xterm.c (x_catch_errors): Remove duplicate declaration.
14456 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
14458 * xdisp.c, lisp.h (message_nolog): Remove; unused.
14460 2011-04-10 Jim Meyering <meyering@redhat.com>
14462 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
14463 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
14464 return ssize_t not "int", and use size_t as the buffer length.
14465 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14466 * gnutls.h: Update declarations.
14467 * process.c (read_process_output): Use ssize_t, to match.
14468 (send_process): Likewise.
14470 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14472 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14474 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14476 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14477 Use unsigned char, to match FcChar8 type definition.
14479 * xterm.c (handle_one_xevent):
14480 * xmenu.c (create_and_show_popup_menu):
14481 * xselect.c (x_decline_selection_request)
14482 (x_reply_selection_request): Avoid type-punned deref of X events.
14484 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14486 Fix some uses of `int' instead of EMACS_INT.
14487 * search.c (string_match_1, fast_string_match)
14488 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
14489 (scan_buffer, find_next_newline_no_quit)
14490 (find_before_next_newline, search_command, Freplace_match)
14491 (Fmatch_data): Make some `int' variables be EMACS_INT.
14493 * xdisp.c (display_count_lines): 3rd argument and return value now
14494 EMACS_INT. All callers changed.
14495 (pint2hrstr): Last argument is now EMACS_INT.
14497 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
14498 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
14499 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
14500 (decode_coding_utf_16, decode_coding_emacs_mule)
14501 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
14502 (decode_coding_ccl, decode_coding_charset)
14503 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
14504 (decode_coding_iso_2022, decode_coding_emacs_mule)
14505 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
14506 <char_offset, last_offset>: Declare EMACS_INT.
14507 (encode_coding_utf_8, encode_coding_utf_16)
14508 (encode_coding_emacs_mule, encode_invocation_designation)
14509 (encode_designation_at_bol, encode_coding_iso_2022)
14510 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
14511 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
14513 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
14514 (encode_invocation_designation): Last argument P_NCHARS is now
14516 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
14517 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
14519 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
14522 * ccl.c (Fccl_execute_on_string): Declare some variables
14525 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
14527 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
14529 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
14531 * process.c (Fformat_network_address): Doc fix.
14533 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
14535 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
14537 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
14539 * keyboard.c (read_char): Call Lisp function help-form-show,
14540 instead of using internal_with_output_to_temp_buffer.
14541 (Qhelp_form_show): New var.
14542 (syms_of_keyboard): Use DEFSYM macro.
14544 * print.c (internal_with_output_to_temp_buffer): Function deleted.
14546 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
14548 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
14550 * process.c (Flist_processes): Remove to Lisp.
14551 (list_processes_1): Delete.
14553 2011-04-06 Eli Zaretskii <eliz@gnu.org>
14555 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
14557 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
14559 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
14561 Fix more problems found by GCC 4.6.0's static checks.
14563 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
14565 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
14567 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14569 * xdisp.c (vmessage): Mark as a printf-like function.
14571 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
14573 * sound.c (sound_warning): Don't crash if arg contains a printf format.
14575 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
14576 printf-like functions.
14577 (tiff_load): Add casts to remove these marks before passing them
14578 to system-supplied API.
14580 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14582 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14583 This avoids several warnings with gcc -Wstrict-overflow.
14584 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14585 directly, rather than having caller test rule sign. This avoids
14586 some unnecessary tests.
14587 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14588 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14589 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14591 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14592 (xfont_open): Avoid unnecessary tests.
14594 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14596 * composite.h, composite.c (composition_gstring_put_cache):
14597 Use EMACS_INT, not int, for length.
14599 * composite.h (COMPOSITION_DECODE_REFS): New macro,
14600 breaking out part of COMPOSITION_DECODE_RULE.
14601 (COMPOSITION_DECODE_RULE): Use it.
14602 * composite.c (get_composition_id): Remove unused local vars,
14603 by using the new macro.
14605 * textprop.c (set_text_properties_1): Change while to do-while,
14606 since the condition is always true at first.
14608 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14609 (interval_deletion_adjustment): Return unsigned value.
14612 * process.c (list_processes_1, create_pty, read_process_output):
14613 (exec_sentinel): Remove vars that were set but not used.
14614 (create_pty): Remove unnecessary "volatile"s.

14622 (update_syntax_table): Use unsigned instead of int.
14624 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14625 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14626 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14628 * print.c (print_error_message): Avoid int overflow.
14630 * font.c (font_list_entities): Redo for clarity,
14631 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14633 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14634 (font_score): Avoid potential overflow in diff calculation.
14636 * fns.c (substring_both): Remove var that is set but not used.
14637 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14639 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14641 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14642 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14643 can always succeed if overflow has undefined behavior.
14645 * search.c (boyer_moore, wordify): Remove vars set but not used.
14646 (wordify): Omit three unnecessary tests.
14648 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14649 All callers changed. This avoids the need for an unused var.
14651 * casefiddle.c (casify_region): Remove var that is set but not used.
14653 * dired.c (file_name_completion): Remove var that is set but not used.
14655 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14657 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14658 (Finsert_file_contents): Remove unnecessary code checking fd.
14660 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14661 Check for integer overflow on size calculations.
14663 * buffer.c (Fprevious_overlay_change): Remove var that is set
14666 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14667 Remove vars that are set but not used.
14668 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14669 (timer_check_2): Mark vars as initialized.
14671 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14673 * image.c (lookup_image): Remove var that is set but not used.
14674 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14676 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14677 that are set but not used.
14679 * xfns.c (make_invisible_cursor): Don't return garbage
14680 if XCreateBitmapFromData fails (Bug#8410).
14682 * xselect.c (x_get_local_selection, x_handle_property_notify):
14683 Remove vars that are set but not used.
14685 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

14695 (map_tty_color) [!defined MSDOS]: Likewise.
14697 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14699 * coding.c: Remove vars that are set but not used.
14700 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14701 All callers changed.
14702 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
14703 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
14704 (decode_coding_charset): Remove vars that are set but not used.
14706 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
14707 that is set but not used.
14709 * print.c (print_object): Remove var that is set but not used.
14711 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14712 The gnulib version avoids calling malloc in the usual case,
14713 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14714 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14715 * filelock.c (current_lock_owner): Likewise.
14716 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14717 * sysdep.c: Include allocator.h, careadlinkat.h.

14719 (emacs_readlink): New function.
14720 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14721 ../lib/careadlinkat.h.
14723 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14725 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14726 first non-nil return value).
14728 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
14730 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
14731 if not defined (Bug#8403).

14740 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
14741 and thereabouts. All callers changed.
14742 (get_per_char_metric): Remove parameter `f', unused since
14743 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

14747 do not dereference NULL upon failed strdup
14748 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14749 (ns_get_family): Likewise.
14751 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14753 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

14790 (Fcommandp): Handle closures.
14791 (Feval): New `lexical' arg.
14792 (eval_sub): New function extracted from Feval. Use it almost

14804 * data.c (Finteractive_form): Handle closures.
14806 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14809 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14811 (exec_byte_code): New function extracted from Fbyte_code to handle new
14812 calling convention for byte-code-functions. Add new byte-codes.
14814 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14816 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14818 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14820 * xdisp.c (redisplay_internal): Fix prototype.
14822 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14824 * xdisp.c (SCROLL_LIMIT): New macro.
14825 (try_scrolling): Use it when setting scroll_limit.
14826 Limit scrolling to 100 screen lines.
14827 (redisplay_window): Even when falling back on "recentering",
14828 position point in the window according to scroll-conservatively,
14829 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14831 (try_scrolling): When point is above the window, allow searching
14832 as far as scroll_max, or one screenful, to compute vertical
14833 distance from PT to the scroll margin position. This prevents
14834 try_scrolling from unnecessarily failing when
14835 scroll-conservatively is set to a value slightly larger than the
14836 window height. Clean up the case of PT below the margin at bottom
14837 of window: scroll_max can no longer be INT_MAX. When aggressive
14838 scrolling is in use, don't let point enter the opposite scroll
14839 margin as result of the scroll.
14840 (syms_of_xdisp) <scroll-conservatively>: Document the
14841 threshold of 100 lines for never-recentering scrolling.
14843 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14845 * dispextern.h (move_it_by_lines):
14846 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14847 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
14848 (message_log_check_duplicate): Remove parameters `prev_bol' and
14849 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14850 (redisplay_internal): Remove parameter `preserve_echo_area',
14851 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14853 * indent.c (Fvertical_motion):
14854 * window.c (window_scroll_pixel_based, Frecenter):
14855 Don't pass `need_y_p' to `move_it_by_lines'.
14857 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14859 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14860 steal a few bits to be more compact.
14861 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14862 Remove unneeded casts.
14864 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14866 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14868 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14869 binding" message (bug#7967).
14871 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14873 Fix more problems found by GCC 4.6.0's static checks.
14875 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14876 Remove unused local var.
14878 * editfns.c (Fmessage_box): Remove unused local var.
14880 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14881 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14882 Omit unused local vars.
14883 * window.c (shrink_windows): Omit unused local var.
14884 * menu.c (digest_single_submenu): Omit unused local var.
14885 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14886 Omit unused local var.
14888 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14889 Don't assume string length fits in int.
14890 (keyremap_step, read_key_sequence): Use size_t for sizes.
14891 (read_key_sequence): Don't check last_real_key_start redundantly.
14893 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14894 instead of alloca (Bug#8344).
14896 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14897 (Fbacktrace_frame): Don't assume nframes fits in int.
14899 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14901 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14904 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14906 * cm.c (calccost): Turn while-do into do-while, for clarity.
14908 * keyboard.c (syms_of_keyboard): Use the same style as later
14909 in this function when indexing through an array. This also
14910 works around GCC bug 48267.
14912 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14914 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14916 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14917 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14919 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14920 This avoids undefined behavior on integer overflow, and is a bit
14921 more convenient anyway since it is compared to a size_t variable.
14923 Variadic C functions now count arguments with size_t, not int.
14924 This avoids an unnecessary limitation on 64-bit machines, which
14925 caused (substring ...) to crash on large vectors (Bug#8344).
14926 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14927 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14928 All variadic functions and their callers changed accordingly.
14929 (struct gcpro.nvars): Now size_t, not int. All uses changed.
14930 * data.c (arith_driver, float_arith_driver): Likewise.
14931 * editfns.c (general_insert_function): Likewise.
14932 * eval.c (struct backtrace.nargs, interactive_p)
14933 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14934 (funcall_lambda, mark_backtrace): Likewise.
14935 * fns.c (concat): Likewise.
14936 * frame.c (x_set_frame_parameters): Likewise.
14937 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14938 0 if not found, not -1. All callers changed.
14940 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14941 (stack_copy_size): Now size_t, not int.
14942 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14944 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14946 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14947 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14948 All callers changed.
14950 * lisp.h (multibyte_char_to_unibyte):
14951 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14952 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14953 * character.h (CHAR_TO_BYTE8):
14954 * cmds.c (internal_self_insert):
14955 * editfns.c (general_insert_function):
14956 * keymap.c (push_key_description):
14957 * search.c (Freplace_match):
14958 * xdisp.c (message_dolog, set_message_1): All callers changed.
14960 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14962 * keyboard.c (safe_run_hook_funcall): New function.
14963 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14964 don't set the hook to nil, but remove the offending function instead.
14965 (Qcommand_hook_internal): Remove, unused.
14966 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14967 Vcommand_hook_internal.
14969 * eval.c (enum run_hooks_condition): Remove.
14970 (funcall_nil, funcall_not): New functions.
14971 (run_hook_with_args): Call each function through a `funcall' argument.
14972 Remove `cond' argument, now redundant.
14973 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14974 (Frun_hook_with_args_until_failure): Adjust accordingly.
14975 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14977 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14979 * dispextern.h (string_buffer_position): Remove declaration.
14981 * print.c (strout): Remove parameter `multibyte', unused since
14982 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14984 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14985 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14986 All callers changed.
14988 * w32.c (_wsa_errlist): Use braces for struct initializers.
14990 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14991 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14992 All callers changed.
14993 (string_buffer_position): Likewise. Also, make static (it's never
14994 used outside xdisp.c).
14995 (cursor_row_p): Remove parameter `w', unused since
14996 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

14998 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
14999 All callers changed.
15001 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
15003 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

15007 * nsterm.m (ns_menu_bar_is_hidden): New variable.
15008 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
15009 (ns_update_auto_hide_menu_bar): New functions.
15010 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
15011 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and

15014 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
15016 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
15018 * nsmenu.m (runDialogAt): Remove argument to timer_check.
15020 2011-03-27 Glenn Morris <rgm@gnu.org>
15022 * syssignal.h: Replace RETSIGTYPE with void.
15023 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
15024 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
15025 Replace SIGTYPE with void everywhere.
15026 * s/usg5-4-common.h (SIGTYPE): Remove definition.
15027 * s/template.h (SIGTYPE): Remove commented out definition.
15029 2011-03-26 Eli Zaretskii <eliz@gnu.org>
15031 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
15032 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
15034 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
15036 * w32.c (read_unc_volume): Use parameter `henum', instead of
15037 global variable `wget_enum_handle'.
15039 * keymap.c (describe_vector): Remove parameters `indices' and
15040 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

15043 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
15045 * keyboard.c (timer_check): Remove parameter `do_it_now',
15046 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
15047 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
15048 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
15050 * keyboard.c (read_char):
15051 * w32menu.c (w32_menu_display_help):
15052 * xmenu.c (show_help_event, menu_help_callback):
15053 Adjust calls to `show_help_echo'.
15055 * gtkutil.c (xg_maybe_add_timer):
15056 * keyboard.c (readable_events):
15057 * process.c (wait_reading_process_output):
15058 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
15060 * insdel.c (adjust_markers_gap_motion):
15061 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
15062 (gap_left, gap_right): Don't call it.
15064 2011-03-25 Chong Yidong <cyd@stupidchicken.com>

15108 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
15110 * w32term.c (x_set_glyph_string_clipping):
15111 Don't pass uninitialized region to CombineRgn.
15113 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
15115 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
15116 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
15117 (Fx_close_connection): Remove unused variable `i'.

15133 (uniscribe_font_driver): Add missing initializers.
15135 2011-03-23 Julien Danjou <julien@danjou.info>
15137 * term.c (Fsuspend_tty, Fresume_tty):
15138 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
15139 * window.c (temp_output_buffer_show):
15140 * insdel.c (signal_before_change):
15141 * frame.c (Fhandle_switch_frame):

15144 * editfns.c (save_excursion_restore):
15145 * cmds.c (internal_self_insert):
15146 * callint.c (Fcall_interactively):
15147 * buffer.c (Fkill_all_local_variables):
15148 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
15150 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
15151 unconditionally since it does the check itself.
15153 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
15155 Fix more problems found by GCC 4.5.2's static checks.
15157 * coding.c (encode_coding_raw_text): Avoid unnecessary test
15158 the first time through the loop, since we know p0 < p1 then.
15159 This also avoids a gcc -Wstrict-overflow warning.
15161 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
15162 leading to a memory leak, possible in functions like
15163 load_charset_map_from_file that can allocate an unbounded number
15164 of objects (Bug#8318).
15166 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
15167 that could (at least in theory) be that large.
15169 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
15170 This is less likely to overflow, and avoids undefined behavior if
15171 overflow does occur. All callers changed. Use strtoul to scan
15172 for the unsigned long integer.
15173 (pint2hrstr): Simplify and tune code slightly.
15174 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
15176 * scroll.c (do_scrolling): Work around GCC bug 48228.
15177 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
15179 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
15180 This also avoids a warning with gcc -Wstrict-overflow.
15181 (validate_x_resource_name): Simplify count usage.
15182 This also avoids a warning with gcc -Wstrict-overflow.
15184 * fileio.c (Fcopy_file): Report error if fchown or fchmod
15187 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
15189 * process.c (Fmake_network_process): Use socklen_t, not int,
15190 where POSIX says socklen_t is required in portable programs.
15191 This fixes a porting bug on hosts like 64-bit HP-UX, where
15192 socklen_t is wider than int (Bug#8277).
15193 (Fmake_network_process, server_accept_connection):
15194 (wait_reading_process_output, read_process_output):
15197 * process.c: Rename or move locals to avoid shadowing.
15198 (list_processes_1, Fmake_network_process):
15199 (read_process_output_error_handler, exec_sentinel_error_handler):
15200 Rename or move locals.
15201 (Fmake_network_process): Define label "retry_connect" only if needed.
15202 (Fnetwork_interface_info): Fix pointer signedness.
15203 (process_send_signal): Add cast to avoid pointer signedness problem.
15204 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
15205 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
15207 Make tparam.h and terminfo.c consistent.
15208 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
15209 Include tparam.h instead, since it declares them.
15210 * cm.h (PC): Remove extern decl; tparam.h now does this.
15211 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
15212 * terminfo.c: Include tparam.h, to check interfaces.
15213 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
15214 (tparam): Adjust signature to match interface in tparam.h;
15215 this removes some undefined behavior. Check that outstring and len
15216 are zero, which they always are with Emacs.
15217 * tparam.h (PC, BC, UP): New extern decls.
15219 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
15220 (xftfont_open): Rename locals to avoid shadowing.
15222 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
15223 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
15224 (OTF_TAG_SYM): Omit macro if not needed.
15225 (ftfont_list): Remove unused local.
15226 (get_adstyle_property, ftfont_pattern_entity):
15227 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
15228 Rename locals to avoid shadowing.
15230 * xfont.c (xfont_list_family): Mark var as initialized.
15232 * xml.c (make_dom): Now static.
15234 * composite.c (composition_compute_stop_pos): Rename local to
15236 (composition_reseat_it): Remove unused locals.
15237 (find_automatic_composition, composition_adjust_point): Likewise.

15271 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
15273 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
15274 This should get cleaned up, so that child_setup has the
15275 same signature on all platforms.
15277 * callproc.c (call_process_cleanup): Now static.
15278 (relocate_fd): Rename locals to avoid shadowing.
15280 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

15409 some of which prompt warnings from gcc -Wbad-function-cast.
15410 (Fformat_time_string, Fencode_time, Finsert_char):

15439 (Fmemory_limit): Cast sbrk's returned value to char *.
15441 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

15447 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15448 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
15449 to use the following functions instead of these macros.
15450 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
15451 EMACS_INT, since callers assume the returned value fits in int.
15452 (upcase1): Likewise, for UPCASE_TABLE.
15453 (uppercasep, lowercasep, upcase): New static inline functions.
15454 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

15464 (regex_compile, re_match_2_internal): Mark locals as initialized.
15465 (RETALLOC_IF): Define only if needed.
15466 (WORDCHAR_P): Likewise. This one is never needed, but is used
15467 only in a comment talking about a compiler bug, so put inside
15468 the #if 0 of that comment.
15469 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15470 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

15496 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
15497 New macros, so that the caller can use some names other than
15498 gcpro1, gcpro2, etc.
15499 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15501 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15502 argument, for consistency with GCPRO2_VAR, etc: it is now the
15503 prefix of the variable, not the variable itself. All uses
15505 * dired.c (directory_files_internal, file_name_completion):
15506 Rename locals to avoid shadowing.
15508 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15509 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15510 dired.c's scmp function, had undefined behavior.
15511 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15512 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15513 * buffer.h: ... to here, because these macros use current_buffer,
15514 and the new implementation with inline functions needs to have
15515 current_buffer in scope now, rather than later when the macros
15517 (downcase, upcase1): New static inline functions.
15518 (DOWNCASE, UPCASE1): Reimplement using these functions.
15519 This avoids undefined behavior in expressions like
15520 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15521 from race conditions in accessing the global variables
15522 case_temp1 and case_temp2.
15523 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15524 * lisp.h (case_temp1, case_temp2): Remove their decls.
15525 * character.h (ASCII_CHAR_P): Move from here ...
15526 * lisp.h: ... to here, so that the inline functions mentioned
15527 above can use them.
15529 * dired.c (directory_files_internal_unwind): Now static.
15531 * fileio.c (file_name_as_directory, directory_file_name):

15534 (file_name_as_directory): Use const pointers when appropriate.
15535 (Fexpand_file_name): Likewise. In particular, newdir might
15536 point at constant storage, so make it a const pointer.
15537 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
15538 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15540 (Fset_file_times, Finsert_file_contents, auto_save_error):

15545 to avoid shadowing.
15547 * marker.c (bytepos_to_charpos): Remove; unused.
15549 * lisp.h (verify_bytepos, count_markers): New decls,
15550 so that gcc does not warn that these functions aren't declared.
15552 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15553 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15554 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15555 (copy_text): Remove unused local var.
15557 * filelock.c (within_one_second): Now static.
15558 (lock_file_1): Rename local to avoid shadowing.
15560 * buffer.c (fix_overlays_before): Mark locals as initialized.
15561 (fix_start_end_in_overlays): Likewise. This function should be
15562 simplified by using pointers-to-pointers, but that's a different
15564 (switch_to_buffer_1): Now static.
15565 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15566 (report_overlay_modification): Rename locals to avoid shadowing.
15568 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
15569 Fix pointer signedness issue.
15570 (sys_subshell): Mark local as volatile if checking for lint,
15571 to suppress a gcc -Wclobbered warning that does not seem to be right.
15572 (MAXPATHLEN): Define only if needed.
15574 * process.c (serial_open, serial_configure): Move decls from here ...
15575 * systty.h: ... to here, so that they can be checked.
15577 * fns.c (get_random, seed_random): Move extern decls from here ...
15578 * lisp.h: ... to here, so that they can be checked.
15580 * sysdep.c (reset_io): Now static.
15581 (wait_for_termination_signal): Remove; unused.
15583 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

15586 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
15587 (DENSE_TABLE_SIZE): Remove; unused.
15588 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
15589 (describe_map_tree):
15590 Rename locals to avoid shadowing.
15592 * keyboard.c: Declare functions static if they are not used elsewhere.

15677 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
15678 These macros can no longer be used for assignment.
