1 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3 * lisp.h (functionp): New function (extracted from Ffunctionp).
5 * eval.c (Ffunctionp): Use it.
7 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
9 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
10 as that's faster and simpler than static storage. Don't bother
11 with the g_main_context_query overhead if g_main_context_pending
12 says no events are pending.
13 (gfds, gfds_size): Remove these static vars.
14 (xgselect_initialize): Remove; no longer needed.
15 All uses and decls removed.
17 * emacs.c (fatal_error_signal_hook): Remove.
18 All uses removed. This leftover from old code was always 0.
20 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
21 * casefiddle.c (casify_object, casify_region):
22 * casetab.c (set_case_table):
23 * category.c, category.h (word_boundary_p):
24 * category.h (CHAR_HAS_CATEGORY):
25 Use bool for booleans, instead of int.
27 2012-08-25 Eli Zaretskii <eliz@gnu.org>
29 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
31 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
33 On assertion failure, print backtrace if available.
34 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
35 (die) [ENABLE_CHECKING]: Print a backtrace if available.
36 * Makefile.in (LIB_EXECINFO): New macro.
39 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
40 * bytecode.c (exec_byte_code):
41 * callint.c (check_mark, Fcall_interactively):
42 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
43 (getenv_internal, sync_process_alive, call_process_exited):
44 * lisp.h (USE_SAFE_ALLOCA):
45 Use bool for booleans, instead of int.
46 * lisp.h, process.h: Adjust prototypes to match above changes.
47 * callint.c (Fcall_interactively): Don't assume the mark's
50 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
52 * buffer.c, buffer.h: Use bool for boolean.
53 * buffer.c (reset_buffer_local_variables)
54 (buffer_lisp_local_variables, Fset_buffer_modified_p)
55 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
56 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
57 (overlay_touches_p, overlay_strings, Foverlay_put)
58 (report_overlay_modification, call_overlay_mod_hooks):
59 (mmap_enlarge, mmap_set_vars):
60 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
61 Use bool for booleans, instead of int.
62 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
63 since the 1-or-0 return value is always ignored anyway.
65 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
66 * buffer.h, lisp.h: Adjust prototypes to match above changes.
68 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
70 * bidi.c: Use bool for boolean.
71 This is a bit more readable, and makes the text segment of bidi.o
72 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
73 Presumably it's faster too.
74 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
76 (bidi_cache_find_level_change, bidi_cache_iterator_state)
77 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
78 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
79 (bidi_explicit_dir_char, bidi_level_of_next_char)
80 (bidi_find_other_level_edge, bidi_move_to_visually_next):
81 Use bool for booleans, instead of int.
82 * dispextern.h (bidi_init_it, bidi_paragraph_init)
83 (bidi_unshelve_cache): Adjust decls to match code.
85 2012-08-23 Martin Rudalics <rudalics@gmx.at>
87 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
90 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
92 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
93 * atimer.h: Include <stdbool.h>.
95 2012-08-22 Dan Nicolaescu <dann@gnu.org>
97 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
98 compile time tests instead of run time tests on systems that do
100 (FRAME_MAC_P): Remove leftover from deleted code.
101 * frame.c (syms_of_frame): Remove leftover from deleted code.
103 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
105 * nsterm.m (insertText:): Don't clear modifiers if code is space.
107 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
109 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
110 Otherwise, the compiler complains about (A?B:C) where B is void
111 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
112 (fontset_add): Return void, for FONTSET_ADD.
114 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
116 * alloc.c: Use bool for booleans.
117 (gc_in_progress, abort_on_gc)
118 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
119 (dont_register_blocks) [GC_MALLOC_CHECK]:
120 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
121 (check_string_bytes, make_specified_string, memory_full)
122 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
123 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
124 (mark_stack, valid_pointer_p, make_pure_string)
125 (Fgarbage_collect, survives_gc_p, gc_sweep):
126 Use bool for booleans, instead of int.
127 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
129 * alloc.c (PURE_POINTER_P):
130 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
131 * editfns.c (Fformat):
132 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
134 * fns.c (sweep_weak_table):
135 * lisp.h (suppress_checking, push_message, survives_gc_p)
136 (make_pure_string, gc_in_progress, abort_on_gc):
137 * lread.c (readchar, read1):
138 * print.c (Fprin1_to_string):
139 * xdisp.c (push_message):
140 Use bool for booleans affected directly or indirectly by
143 Make recently-introduced setters macros.
144 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
145 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
146 (set_fontset_default, set_fontset_fallback): Rename from their
147 upper-case counterparts, and make them functions rather than macros.
148 This is more consistent with the other recently-introduced setters.
149 These don't need to be inline, since they're local.
151 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
153 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
154 the loop (Bug#12247).
156 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
158 * lisp.h (vcopy): Use memcpy rather than our own loop.
159 This fixes a performance regression introduced by the recent
160 addition of vcopy. This means 'vcopy' will need to be modified
161 for a copying collector, but that's OK. Also, tighten the
162 checking in the assertion.
164 2012-08-21 Eli Zaretskii <eliz@gnu.org>
166 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
167 components for RTL text (Bug#11860). Adjust X-OFFSET of each
168 non-base glyph for the width of the base character, according to
169 what x_draw_composite_glyph_string_foreground expects.
170 Generate WADJUST value according to composition_gstring_width's
171 expectations, to produce correct width of the composed character.
172 Reverse the sign of the DU offset produced by ScriptPlace.
174 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
176 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
178 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
180 Avoid direct writes to contents member of struct Lisp_Vector.
181 * lisp.h (vcopy): New function to copy data into vector.
182 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
183 * fns.c (Ffillarray): Use ASET.
184 * keyboard.c (timer_check_2): Use AREF and ASET.
185 (append_tool_bar_item, Frecent_keys): Use vcopy.
186 * lread.c (read_vector): Use ASET.
187 * msdos.c (Frecent_doskeys): Use vcopy.
188 * xface.c (Finternal_copy_lisp_face): Use vcopy.
189 (Finternal_merge_in_global_face): Use ASET and vcopy.
190 * xfont.c (xfont_list_pattern): Likewise.
192 2012-08-21 Martin Rudalics <rudalics@gmx.at>

195 the position of its buffer's point.
196 (Fset_window_point): For the selected window always go in its
197 buffer to the specified position.
199 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
201 Setter macros for fontsets.
202 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
203 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
204 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
207 2012-08-20 Glenn Morris <rgm@gnu.org>
209 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
210 Don't assume that `ln -f' works.
212 2012-08-20 Eli Zaretskii <eliz@gnu.org>
214 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
215 and later about non-assignments with no effect. See discussion at
216 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
219 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
221 Inline setter functions for Lisp_Objects slots of struct specbinding.
222 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
225 2012-08-20 Martin Rudalics <rudalics@gmx.at>
227 * window.c (select_window): Always make selected window's buffer
230 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
232 Use AREF and ASET for docstrings of category tables.
233 * category.h (CATEGORY_DOCSTRING): Use AREF.
234 (SET_CATEGORY_DOCSTRING): Use ASET.
235 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
237 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
239 Inline setter functions for hash table members.
240 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
241 (set_hash_hash, set_hash_index): Rename with _slot suffix.
242 (set_hash_key_and_value, set_hash_index, set_hash_next)
243 (set_hash_hash): New functions.
244 * charset.c, fns.c: Adjust users.
246 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
248 Inline getter and setter functions for per-buffer values.
249 * buffer.h (per_buffer_default, set_per_buffer_default)
250 (per_buffer_value, set_per_buffer_value): New functions.
251 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
252 * buffer.c, data.c: Adjust users.
254 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
256 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
258 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
260 Rely on <config.h> + <unistd.h> to declare 'environ',
261 as gnulib does this if the system doesn't.
262 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
263 Remove declaration. MS-Windows declares it on stdlib.h which is
264 included by conf_post.h.
265 * emacs.c (environ) [DOUG_LEA_MALLOC]:
266 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
267 * vm-limit.c: Include <unistd.h>, for 'environ'.
269 * unexaix.c, unexcoff.c: Include "mem-limits.h".
270 (start_of_data): Remove decl; mem-limits.h provides it.
272 * xdisp.c (handle_invisible_prop): Make it a bit faster
273 and avoid a gcc -Wmaybe-uninitialized diagnostic.
275 2012-08-19 Chong Yidong <cyd@gnu.org>
277 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
280 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
282 * .gdbinit: Use call instead of set when calling a function in the
285 * data.c (set_internal): Don't use set_blv_found.
286 (Fkill_local_variable): Likewise.
288 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
290 * nsfont.m (ns_ascii_average_width): Ensure the string
291 ascii_printable is initialized with a null-terminated character
292 array. Otherwise, it can contain undesired extra characters.
294 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
296 port new setting code to Sun C 5.8 2005/10/13
297 * chartab.c, lisp.h (char_table_set, char_table_set_range):
298 Return void, not Lisp_Object. Otherwise, the compiler
299 complains about (A?B:C) where B is void and C is Lisp_Object
300 when compiling CHAR_TABLE_SET, due to the recent change to
301 the API of sub_char_table_set_contents.
303 2012-08-18 Chong Yidong <cyd@gnu.org>
305 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

400 (kset_prefix_arg, kset_system_key_alist, kset_window_system):
401 New setter functions.

1133 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
1134 * w32.c (init_environment): Change the default values of many
1135 environment variables in dflt_envvars[] to NULL, to avoid pushing
1136 them into environment when they were not already defined.
1137 Remove the code that deletes site-lisp subdirectories from the default
1138 value of EMACSLOADPATH, as it is no longer needed.
1139 (check_windows_init_file): Now external, not static.
1140 Use Vload_path as is, without adding anything, as this function is now
1141 called when Vload_path is already set up.
1143 * w32.h (check_windows_init_file): Add prototype.
1145 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

1152 installation tree, as appropriate.
1154 * callproc.c (init_callproc_1): Call decode_env_path instead of
1155 doing its equivalent by hand.

1173 Remove unnecessary casts involving pointers.
1174 These casts are no longer needed now that we assume C89 or later,

1189 Remove unnecessary pointer casts.
1190 * alloc.c (record_xmalloc): New function.
1191 * lisp.h (record_xmalloc): New decl.
1192 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
1193 more like a function. This is because the pointer cast is not
1194 needed. All uses changed.
1195 * print.c (print_string, print_error_message): Avoid length recalc.
1197 Improve fix for macroexp crash with debugging (Bug#12118).
1198 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
1199 ARRAY_MARK_FLAG when checking subscripts, because ASET is
1200 not supposed to be invoked from the garbage collector.

1202 (gc_aset): New function, which is like ASET but can be
1203 used in the garbage collector.

1232 with addition of handling of symlinks and support for 'lstat'.
1233 If possible, get file's attributes and security information by
1234 handle, not by name. Produce S_IFLNK bit for symlinks, when
1235 called from 'lstat'.
1236 (stat, lstat): New functions, call 'stat_worker'.
1237 (symlink, readlink, careadlinkat): Rewritten to create and resolve
1238 symlinks when the underlying filesystem supports them.
1240 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
1242 Fix macroexp crash on Windows with debugging (Bug#12118).
1243 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
1244 checking subscripts; problem introduced with the recent
1245 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
1246 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
1247 since it's used in non-static inline functions now.
1249 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
1250 Don't assume buffer size fits in 'int'. Remove unused local.

1270 * composite.c (COMPOSITE_INLINE):
1271 * dispnew.c (DISPEXTERN_INLINE):
1272 * sysdep.c (SYSTIME_INLINE):
1273 Define to EXTERN_INLINE, so that the corresponding functions
1274 are compiled into code.
1275 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
1276 (INLINE_HEADER_END): New macros.
1277 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

1297 hard-coding the path separator.
1299 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
1301 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
1302 This how ASET and AREF are supposed to work, and makes
1303 it easier to think about future improvements. See
1304 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
1305 * charset.h (set_charset_attr): New function.

1820 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1821 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1822 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1823 Adjust to changes in lisp.h and emacs.c, by using
1824 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1825 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1826 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1827 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1828 instead of gdb_valbits.
1829 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use

1831 instead of gdb_array_mark_flag.
1832 (xboolvector): Get size from $->size, not $->header.size.
1833 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1834 (xreload, hook-run, hookpost-run): Remove.
1835 * emacs.c: Include <verify.h>.
1836 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)

1843 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
1844 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
1845 as constants, so they're visible to GDB.

1847 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
1848 Now enum constants, not macros, so they're visible to GDB.
1849 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1850 more convenient now. All uses changed.
1851 (VALMASK) [USE_LSB_TAG]: Also define in this case.

1867 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1868 than macros. This simplifies debugging in the usual case, since
1869 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1870 and it allows expressions involving EMACS_INT casts.
1871 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1873 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

1925 Swap buffer text indirection counters in Fbuffer_swap_text.
1926 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1927 This avoids crash reported by Christoph Scholtes at
1928 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1930 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1932 * nsmenu.m (Popdown_data): New struct.

1955 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
1957 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
1958 as it's limited by the amount of memory, not by INT_MAX.
1960 2012-07-21 Eli Zaretskii <eliz@gnu.org>
1962 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

2708 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
2709 (add_emacs_time, sub_emacs_time): New functions.
2710 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

2736 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2737 * nsterm.m (ns_term_init):
2738 Avoid the need for strncpy, by using build_string or
2739 make_unibyte_string directly. Use dtoastr, not snprintf.
2740 * process.c (Fmake_network_process): Diagnose service names that
2741 are too long, rather than silently truncating them or creating
2742 non-null-terminated names.
2743 (Fnetwork_interface_info): Likewise, for interface names.
2744 * sysdep.c (system_process_attributes) [GNU_LINUX]:
2745 Prefer sprintf to strncat.
2746 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

2752 Clarify fallback case.
2754 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

2757 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
2758 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
2759 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

2772 Optimize pure C strings initialization.
2773 * lisp.h (make_pure_string): Fix prototype.
2774 (build_pure_c_string): New function, defined as static inline. This
2775 provides a better opportunity to optimize away calls to strlen when
2776 the function is called with compile-time constant argument.
2777 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2778 argument, adjust users accordingly. Use build_pure_c_string where
2780 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
2781 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
2782 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
2784 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
2786 Avoid calls to strlen in miscellaneous functions.
2787 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
2788 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
2789 * lread.c (openp): Likewise.

2793 Avoid calls to strlen in path processing functions.
2794 * fileio.c (file_name_as_directory): Add comment. Change to add
2795 srclen argument and return the length of result. Adjust users

2799 Adjust users accordingly.
2800 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
2802 2012-07-10 Glenn Morris <rgm@gnu.org>
2804 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

2809 * s/gnu.h (DATA_START): Move definitions to configure.
2811 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
2812 We include usg5-4-common.h, which defines them both.
2814 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2815 O_RDONLY already includes it).
2817 Stop ns builds setting the EMACSLOADPATH environment variable.
2818 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2819 Now it does not set EMACSLOADPATH, just returns the load-path string.
2820 * nsterm.h: Update accordingly.
2821 * lread.c [HAVE_NS]: Include nsterm.h.
2822 (init_lread) [HAVE_NS]: Use ns_load_path.

2825 2012-07-09 Glenn Morris <rgm@gnu.org>
2827 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2828 since the included bsd-common.h does so.
2830 Stop ns builds setting the EMACSPATH environment variable.
2831 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2832 (ns_init_paths): Do not set EMACSPATH.
2833 * nsterm.h (ns_exec_path): Add it.
2834 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2837 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2839 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2841 * process.c (wait_reading_process_output): 'waitchannels' was unset
2842 when read_kbd || !NILP (wait_for_cell); fix this.
2844 Add GCC-style 'const' attribute to functions that can use it.
2845 * character.h (char_resolve_modifier_mask):
2846 * keyboard.h (make_ctrl_char):
2847 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

2854 Declare the dummy function with ATTRIBUTE_CONST.
2855 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2856 Add decls with ATTRIBUTE_CONST.
2858 Minor improvements to make_formatted_string.
2859 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2860 where int is good enough, as vsprintf returns an int.
2861 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2863 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2865 Use make_formatted_string to avoid double length calculation.
2866 * lisp.h (make_formatted_string): New prototype.
2867 * alloc.c (make_formatted_string): New function.
2868 * buffer.c (Fgenerate_new_buffer_name): Use it.

2890 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2892 Move marker debugging code under MARKER_DEBUG.
2893 * marker.c (MARKER_DEBUG): Move marker debugging code under
2894 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2895 for bootstrap with --enable-checking (~3x slowdown reported
2896 by Juanma Barranquero <lekktu@gmail.com>).
2897 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2899 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2901 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2902 See <http://bugs.gnu.org/11825#29>.
2904 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2906 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2907 has no font, use the frame's font. (Bug#11813)
2908 (display_line): Add commentary about displaying truncation glyphs
2910 (produce_special_glyphs): Move here from term.c.
2912 * term.c (produce_special_glyphs): Move to xdisp.c.
2914 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2917 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2919 * xdisp.c (display_line): Avoid warning about implicit declaration
2922 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2924 * lisp.h: Remove empty conditional.
2926 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2928 * lread.c (load_path_check): Now static.
2930 Fix some minor --with-ns problems found by static checking.
2931 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2932 (x_set_font) [!HAVE_X_WINDOWS]:
2933 * image.c (xpm_load_image) [HAVE_NS]:
2934 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2935 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2936 Remove unused local.
2937 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2938 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2939 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2940 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2941 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2942 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2943 Fix pointer signedness problem.
2944 * xfaces.c (FRAME_X_FONT_TABLE):
2945 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2947 2012-07-07 Glenn Morris <rgm@gnu.org>
2949 * lread.c (load_path_check): New function, split from init_lread.
2950 (init_lread): Reorganize. Motivation:
2951 If EMACSLOADPATH is set, check/warn about that rather than the
2952 defaults, which we are not going to use. Hence we can remove
2953 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2954 Don't warn if site-lisp directories are missing.
2955 If not installed, start from a blank load-path, since
2956 PATH_LOADSEARCH refers to the eventual installation directories.
2958 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2960 Support truncation and continuation glyphs on GUI frames, when
2961 fringes are disabled. (Bug#11832)
2962 * xdisp.c (init_iterator): Get dimensions of truncation and
2963 continuation glyphs even if on GUI frames.
2964 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2965 or both, are absent.
2966 (start_display, move_it_in_display_line_to): Handle the case of a
2967 GUI frame without a fringe to display continuation or truncation
2969 (insert_left_trunc_glyphs): Support GUI frames: make sure
2970 truncation glyphs overwrite enough glyphs from the current line to
2971 have sufficient space in pixels.
2972 (display_line): Support truncation and continuation glyphs on GUI
2973 frames. If some spare pixels are left on the line after inserting
2974 the truncation glyphs, fill that space with a stretch glyph of a
2975 suitably computed width.
2977 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2978 produce_glyphs, to support GUI sessions.
2980 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2982 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2984 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2986 Do not require float-time's arg to fit in time_t (Bug#11825).
2987 This works better on hosts where time_t is unsigned, and where
2988 float-time is applied to the (negative) difference between two times.
2989 * editfns.c (decode_time_components): Last arg is now double *,
2990 not int *, and means to store all the result as a double, without
2991 worrying about whether the seconds part fits in time_t.
2992 All callers changed.
2993 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2994 All callers changed.
2995 (Ffloat_time): Do not fail merely because the specified time falls
2996 outside of time_t range.
2998 2012-07-07 Glenn Morris <rgm@gnu.org>
3000 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
3001 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

3015 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
3016 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
3017 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
3018 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
3020 * xfont.c (compare_font_names): Redo to omit the need for casts.
3022 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
3024 * xfns.c (Fx_change_window_property): Doc fix.
3025 * w32fns.c (Fx_change_window_property): Doc fix.
3027 * w32fns.c (Fx_window_property): Accept the same arguments as the
3028 X Windows version. Doc fix.
3029 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
3031 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
3032 Eli Zaretskii <eliz@gnu.org>
3034 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
3035 Windows-specific code from nt/config.nt moved here.
3036 Obsolete settings removed.
3038 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3040 * process.c: Avoid unnecessary calls to gettime.
3041 (wait_reading_process_output): Don't get the time of day
3042 when gobbling data immediately and not waiting, as there's no need
3043 for it in that case. This removes a FIXME.
3045 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
3047 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
3048 is defined (Bug#11768).
3050 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3052 Fix marker debugging code.
3053 * marker.c (byte_char_debug_check): Do not perform the check
3054 if buffer is not multibyte.
3055 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3056 Call byte_char_debug_check with correct arguments.
3058 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3060 Compile marker debugging code only if ENABLE_CHECKING is defined.
3061 * marker.c (byte_char_debug_check, count_markers):
3062 Use only if ENABLE_CHECKING is defined.
3063 (byte_debug_flag): Remove.
3064 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
3065 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
3067 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3069 Avoid code repetition in marker-related functions.
3070 * marker.c (attach_marker): New function.
3071 (Fset_marker, set_marker_restricted, set_marker_both)
3072 (set_marker_restricted_both): Use it.
3073 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
3074 Consistently rename charno to charpos.
3075 (marker_position): Add eassert.
3076 (marker_byte_position): Convert to eassert.

3095 * window.c (save_window_save): Likewise.
3097 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
3099 Do not use Fdelete_overlay in delete_all_overlays
3100 to avoid redundant calls to unchain_overlay.
3101 * buffer.c (drop_overlay): New function.
3102 (delete_all_overlays, Fdelete_overlay): Use it.
3103 * minibuf.c (get_minibuffer): Fix comment.
3105 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
3107 Port to OpenBSD 5.1 amd64.
3108 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
3109 This is needed for OpenBSD, and should be harmless on all BSD systems.
3110 Also, include <sys/sysctl.h>, as it should be available on all
3111 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
3112 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
3113 use p_pid member, not kp_proc.pid.
3115 2012-07-06 Glenn Morris <rgm@gnu.org>
3117 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
3119 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
3121 More xmalloc and related cleanup.
3122 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
3123 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
3124 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
3125 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
3126 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
3127 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
3128 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
3129 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
3130 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
3132 Omit needless casts involving void * pointers and allocation.
3133 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
3134 as the former is more robust if P's type is changed.
3135 Prefer xzalloc to xmalloc + memset 0.
3136 Simplify malloc-or-realloc to realloc.
3137 Don't worry about xmalloc returning a null pointer.
3138 Prefer xstrdup to xmalloc + strcpy.
3139 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
3141 * keyboard.c (apply_modifiers_uncached): Prefer local array to
3142 alloca of a constant.
3144 2012-07-05 Eli Zaretskii <eliz@gnu.org>
3146 * xdisp.c (display_line): Fix horizontal pixel coordinates when
3147 hscroll is larger than the line width. Fixes long and futile
3148 looping inside extend_face_to_end_of_line (on a TTY) producing
3149 glyphs that are not needed and thrown away.
3151 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
3153 * marker.c (set_marker_restricted_both): Simplify by using

3158 * editfns.c (region_limit): Simplify by using clip_to_bounds.
3160 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
3162 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
3163 not defined (Bug#11768).
3164 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
3165 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
3166 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
3167 followed by gtk_box_set_homogeneous (Bug#11768).
3168 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
3169 (update_theme_scrollbar_width, xg_create_scroll_bar):
3170 Use gtk_scrollbar_new (Bug#11768).
3171 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
3172 (is_box_type): New function (Bug#11768).
3173 (xg_tool_item_stale_p): Call is_box_type.
3174 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
3175 with default display (Bug#11768).

3179 * xdisp.c (window_hscroll_limited): New function.
3180 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
3181 coordinates when window's hscroll is set to insanely large
3184 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
3186 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
3187 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
3189 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
3192 * lisp.h (xzalloc): New prototype. Omit needless casts.
3193 * alloc.c (xzalloc): New function. Omit needless casts.

3247 * fileio.c (time_error_value): Check the right error number.
3248 Problem reported by Troels Nielsen in
3249 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
3251 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3253 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
3254 This should be fixed in a better way; see Eli Zaretskii in
3255 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
3256 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
3258 * fileio.c (time_error_value): Rename from special_mtime.
3259 The old name's problems were noted by Eli Zaretskii in
3260 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
3262 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
3263 This variable's comment says Emacs needs at least one GDB-visible
3264 symbol of type enum pvec_type, to work around GDB problems.
3265 The symbol's value doesn't matter.
3267 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
3268 that causes compilation to fail on pre-C99 compilers.
3270 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
3272 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
3273 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
3275 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3277 * buffer.c (init_buffer_once): Fix initialization of
3278 headers for buffer_defaults and buffer_local_symbols.
3279 Reported by Juanma Barranquero <lekktu@gmail.com>.
3281 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
3283 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
3284 * lisp.h (enum pvec_type): Use fewer bits.
3285 (PSEUDOVECTOR_SIZE_BITS): New constant.
3286 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
3287 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
3288 change in pvec_type.
3289 (PSEUDOVECTOR_TYPEP): New macro.
3290 (TYPED_PSEUDOVECTORP): Use it.
3291 * fns.c (internal_equal): Adapt code to extract pvectype.
3292 * emacs.c (gdb_pvec_type): Update type.
3293 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
3294 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
3295 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
3296 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
3297 (sweep_vectors): Use it. Use local var `total_bytes' instead of
3298 abusing vector->header.next.nbytes.
3299 (live_vector_p): Use PVEC_TYPE.
3300 (mark_object): Adapt code to extract pvectype. Use switch.
3302 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3304 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
3305 Tighten new eassert a bit.
3307 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3309 Fix compilation with --enable-gcc-warnings and -O1
3311 * doprnt.c (doprnt): Change type of tem to int, initialize
3312 to avoid compiler warning. Add eassert.
3313 * search.c (simple_search): Initialize match_byte to avoid
3314 compiler warning. Add eassert.
3316 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3318 Avoid weird behavior with large horizontal scrolls.
3319 Without this change, for example, large hscroll values would
3320 mess up Emacs's display on Fedora 15 x86, presumably due to
3321 overflows in int calculations in the display code.
3322 Also, if buffers had long lines, Emacs would freeze.
3323 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
3324 (set_window_hscroll): New function, containing the old guts of
3325 Fset_window_hscroll. Return the clipped value.
3326 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
3327 This avoids the need to check against PTRDIFF_MAX.
3329 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
3331 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
3333 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
3335 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
3337 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
3338 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
3339 since GCC 4.4.6 issues a bogus warning for them.
3341 Fix bugs in file timestamp newness comparisons.
3342 * fileio.c (Ffile_newer_than_file_p):
3343 * lread.c (Fload): Use full timestamp resolution of files,
3344 not just the 1-second resolution, so that files that are only
3345 slightly newer still count as newer.
3346 * fileio.c (Ffile_newer_than_file_p): Don't assume file
3347 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
3349 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
3351 * fileio.c: Improve handling of file time marker. (Bug#11852)
3352 (special_mtime): New function.
3353 (Finsert_file_contents, Fverify_visited_file_modtime):
3354 Use it to set special mtime values consistently.
3356 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
3358 * fileio.c (Finsert_file_contents): Properly handle st_mtime
3359 marker for non-existing file. (Bug#11852)
3361 2012-07-03 Glenn Morris <rgm@gnu.org>
3363 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
3364 and did not make it into globals.h).
3366 2012-07-03 Tom Tromey <tromey@redhat.com>
3368 * window.c (Fset_window_margins, Fset_window_fringes)
3369 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
3370 * textprop.c (Fprevious_property_change): No longer static.
3371 * syntax.c (Fsyntax_table_p): No longer static.

3393 * intervals.h: Remove EXFUNs.
3394 * fontset.h: Remove EXFUN.

3400 * window.h: Remove EXFUNs.

3402 * xterm.h: Remove EXFUN.
3404 2012-07-03 Glenn Morris <rgm@gnu.org>
3406 * lisp.h (Frandom): Make it visible to C.
3407 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
3408 buffer for invisible buffers. (Bug#1229)
3410 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3412 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
3413 values which aren't power of 2.
3414 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
3415 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
3418 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
3420 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
3422 * alloc.c (mark_object): Revert part of last patch to use `switch'.
3424 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3426 * alloc.c (allocate_vector_block): Remove redundant
3427 calls to mallopt if DOUG_LEA_MALLOC is defined.
3428 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
3429 avoid calls to mallopt if zero_vector is returned.
3431 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3433 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
3434 is enabled, avoid dereferencing NULL current_sblock if
3437 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
3439 Cleanup basic buffer management.
3440 * buffer.h (struct buffer): Change layout to use generic vector
3441 marking code. Fix some comments. Change type of 'clip_changed'
3442 to bitfield. Remove unused #ifndef old.
3443 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
3444 (GET_OVERLAYS_AT): Fix indentation.
3445 (for_each_per_buffer_object_at): New macro.
3446 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

3448 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
3449 * alloc.c (allocate_buffer): Adjust to match new layout of
3450 struct buffer. Fix comment.
3451 (mark_overlay): New function.
3452 (mark_buffer): Use it. Use mark_vectorlike to mark normal
3453 Lisp area of struct buffer.
3454 (mark_object): Use it. Adjust marking of misc objects
3455 and related comments.
3457 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
3459 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
3460 wrapper that is not needed because the wrapped code is a no-op (zero
3461 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
3462 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
3464 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
3466 * alloc.c (mark_buffer): Simplify. Remove prototype.
3467 (mark_object): Add comment. Reorganize marking of vector-like
3468 objects. Use CHECK_LIVE for all vector-like objects except buffers
3469 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
3470 Avoid redundant calls to mark_vectorlike for bool vectors.
3472 2012-06-30 Glenn Morris <rgm@gnu.org>
3474 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
3476 * epaths.in (PATH_SITELOADSEARCH): New.
3477 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
3478 This is rather than relying on --enable-locallisppath elements
3479 having "site-lisp" in their names. (Bug#10208#25, 11658)
3481 2012-06-30 Eli Zaretskii <eliz@gnu.org>
3483 * w32proc.c (sys_select): Accept and ignore one more argument.
3485 * w32.c (emacs_gnutls_pull): Call select with one more argument.
3487 * sysselect.h [DOS_NT]: Don't include sys/select.h.
3488 (pselect) [!MS_DOS]: Redirect to sys_select.
3490 * sysdep.c: Don't include dos.h and dosfns.h.
3492 * process.c (sys_select):
3493 * msdos.c (sys_select): Accept one more argument and ignore it.
3495 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
3496 adapt data types and code to that.
3499 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
3500 which clashes with the gnulib function of the same name.
3502 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
3504 * font.c (font_style_to_value, font_style_symbolic)
3505 (font_prop_validate_style): Add type checks for values in
3508 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
3510 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
3513 2012-06-29 Eli Zaretskii <eliz@gnu.org>
3515 * xdisp.c (try_window_id): Undo last change.
3517 * w32.c (getwd): Adjust commentary about startup_dir.
3518 (init_environment): Always call sys_access, even in non-MSVC
3519 builds. Don't chdir to the directory of the Emacs executable.
3520 This undoes code from 1997 which was justified by the need to
3521 "avoid conflicts when removing and renaming directories". But its
3522 downside was that every relative file name was being interpreted
3523 relative to the directory of the Emacs executable, which can never
3524 be TRT. In particular, it broke sys_access when called with
3525 relative file names.
3526 (sys_access): Map GetLastError to errno.
3528 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3530 * window.h (struct window): Change type of 'fringes_outside_margins'

3534 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
3537 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
3539 * gnutls.c (emacs_gnutls_handshake):
3540 Add QUIT to make the loop interruptible.
3542 2012-06-29 Glenn Morris <rgm@gnu.org>
3544 * charset.c (init_charset): Make lack of etc/charsets fatal.
3546 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3548 * editfns.c (region_limit): Fix type mismatch.
3550 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
3552 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
3553 undefined. Convert from xassert to eassert.
3554 * nsmenu.m: Convert from xassert to eassert.
3555 * nsterm.m: Likewise.
3557 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
3559 * editfns.c (region_limit): Clip to narrowing (bug#11770).
3561 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
3563 Avoid integer overflow on scroll-left and scroll-right.
3564 * window.c (HSCROLL_MAX): New macro.
3565 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
3566 overflow when requested scroll falls outside ptrdiff_t range.
3568 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3570 * window.h (struct window): Change type of 'hscroll',
3571 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
3572 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3573 Adjust users accordingly.
3574 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3575 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3576 from EMACS_INT to ptrdiff_t.
3577 (make_window): Omit redundant initialization.
3579 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

3583 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3585 * window.h (struct window): Change type of 'use_time' and
3586 'sequence_number' from Lisp_Object to int.

3595 enabled with --enable-checking=[all,glyphs] configure option.
3596 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3597 adjust comments accordingly.

3718 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3720 Use sprintf return value instead of invoking strlen on result.
3721 In the old days this wasn't portable, since some sprintf
3722 implementations returned char *. But they died out years ago and
3723 Emacs already assumes sprintf returns int.
3724 Similarly for float_to_string.
3725 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
3726 * ccl.c (ccl_driver):
3727 * character.c (string_escape_byte8):

3732 * xfns.c (syms_of_xfns):
3733 Use sprintf or float_to_string result to avoid need to call strlen.
3734 * data.c (Fnumber_to_string):
3735 Use make_unibyte_string, since the string must be ASCII.
3736 * lisp.h, print.c (float_to_string): Now returns int length.
3737 * term.c (produce_glyphless_glyph):
3738 Use sprintf result rather than recomputing it.
3740 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3741 * Makefile.in (ALL_CFLAGS):
3742 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
3743 * gmalloc.c, regex.c: Include <config.h> unconditionally.

3767 sprintf already null-terminates its output.
3769 * xfns.c (x_window): Remove redundant cast.
3771 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
3773 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
3774 `const char *' to `char *' to avoid compiler warning.
3776 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3778 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
3779 instead of truncating it to 63 (admittedly a generous limit).
3781 * process.c: Fix spelling and caps in comments.
3783 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
3785 * emacs.c (setpgrp): Remove definition, unused.

3832 Remove unnecessary forward decls.
3834 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3836 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

3838 * dispnew.c (Fsleep_for, sit_for):
3839 * keyboard.c (kbd_buffer_get_event):
3840 * process.c (Faccept_process_output):
3841 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3842 This improves on the previous patch, which introduced a bug
3843 when time_t is unsigned and as wide as intmax_t.
3844 See <http://bugs.gnu.org/9000#51>.
3846 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3848 * dispnew.c (sit_for, Fsleep_for):
3849 * keyboard.c (kbd_buffer_get_event):

3862 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
3863 Privately reported by Herbert J. Skuhra.
3864 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
3866 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
3867 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3869 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3871 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
3872 last argument of make_unibyte_string.
3874 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
3875 language ID in the event parameters.
3877 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3878 event.code, not the obscure "character set ID".

3901 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
3902 Privately reported by Herbert J. Skuhra.

3909 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3911 Support higher-resolution time stamps (Bug#9000).
3912 The time stamps are only nanosecond-resolution at the C level,
3913 since that's the best that any real-world system supports now.
3914 But they are picosecond-resolution at the Lisp level, as that's
3915 easy, and leaves room for future OS improvements.
3917 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3920 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3921 Don't get current time unless it's needed.
3923 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3924 now provides it if it's absent.
3925 (start_atimer): Port to higher-res time stamps.
3926 Check for time stamp overflow. Don't get current time more
3927 often than is needed.
3929 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3930 Include systime.h, not time.h.
3931 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3933 * dired.c: Include stat-time.h.
3934 (Ffile-attributes): File times now have higher resolution.

3937 (struct image): Timestamp now has higher resolution.
3939 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3940 has at least microseconds now. All uses removed.
3941 (update_frame, update_single_window, update_window, update_frame_1)
3942 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3943 (duration_to_sec_usec): Remove; no longer needed.
3945 * editfns.c (time_overflow): Now extern.
3946 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3947 (float-time, Fformat_time_string, Fcurrent_time_string)
3948 (Fcurrent_time_zone): Accept and generate higher-resolution
3950 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3951 (decode_time_components, lisp_seconds_argument): New functions.
3952 (make_time): Now static.
3953 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3954 Report an error if the time is invalid, rather than having the caller
3957 * fileio.c: Include <stat-time.h>
3958 (Fcopy_file): Copy higher-resolution time stamps.
3959 Prefer to set the time stamp via a file descriptor if that works.

3961 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3962 (Fvisited_file_modtime, Fset_visited_file_modtime):
3963 Support higher-resolution time stamps.
3965 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3967 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3969 * image.c (prepare_image_for_display, clear_image_cache)
3970 (lookup_image): Port to higer-resolution time stamps.
3972 * keyboard.c (start_polling, bind_polling_period):
3973 Check for time stamp overflow.
3974 (read_char, kbd_buffer_get_event, timer_start_idle)
3975 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3976 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3977 Port to higher-resolution time stamps. Do not assume time_t is signed.
3978 (decode_timer): New function. Timers are now vectors of length 9,
3979 not 8, to accommodate the picosecond component.
3980 (timer_check_2): Use it.
3982 * nsterm.m (select_timeout, timeval_subtract): Remove.
3983 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3984 as they're a bit more accurate and handle overflow better.
3985 (ns_select): Change prototype to be compatible with pselect.
3986 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3987 * nsterm.h (ns_select): Adjust prototype.
3989 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3990 us-resolution time stamps.
3991 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3993 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3995 * lisp.h (time_overflow): New decl.
3996 (wait_reading_process_output): First arg is now intmax_t, not int,
3997 to accommodate larger waits.
3999 * process.h (struct Lisp_Process.read_output_delay):
4000 Now counts nanoseconds, not microseconds.
4001 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
4003 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
4004 (wait_reading_process_output):
4005 Port to ns-resolution time stamps.
4006 (Faccept_process_output, wait_reading_process_output):
4007 Check for time stamp overflow. Do not assume time_t is signed.
4008 (select_wrapper): Remove; we now use pselect.
4009 (Fprocess_attributes): Now generates ns-resolution time stamps.
4011 * sysdep.c: Include utimens.h. Don't include utime.h
4012 or worry about struct utimbuf; gnulib does that for us now.
4013 (gettimeofday): Remove; gnulib provides a substitute.
4014 (make_timeval): New function.
4015 (set_file_times): Now sets ns-resolution time stamps.
4016 New arg FD; all uses changed.
4017 (time_from_jiffies, ltime_from_jiffies, get_up_time)
4018 (system_process_attributes):
4019 Now returns ns-resolution time stamp. All uses changed.
4020 Check for time stamp overflow.
4022 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
4023 provides a substitute now.
4025 * systime.h: Include timespec.h rather than sys/time.h and time.h,
4026 since it guarantees struct timespec.
4027 (EMACS_TIME): Now struct timespec, so that we can support
4028 ns-resolution time stamps.
4029 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
4030 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
4031 (EMACS_USECS): Remove.
4032 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
4033 so multiply the arg by 1000 before storing it.
4034 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
4036 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
4037 Port to ns-resolution time stamps.
4038 (EMACS_TIME_NEG_P): Remove; replaced by....
4039 (EMACS_TIME_SIGN): New macro.
4040 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
4041 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

4043 (make_timeval, make_lisp_time, decode_time_components): New decls.
4044 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
4045 that it mishandled time_t overflow. You can't compare by subtracting!
4046 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
4047 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
4049 * term.c: Include <sys/time.h>.
4050 (timeval_to_Time): New function, for proper overflow wraparound.

4053 * undo.c (record_first_change): Support higher-resolution time stamps
4055 (Fprimitive_undo): Use them when restoring time stamps.
4057 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
4058 (w32_get_internal_run_time):
4059 Port to higher-resolution Emacs time stamps.
4060 (ltime): Now accepts single 64-bit integer, as that's more convenient
4063 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
4065 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
4066 for compatibility with pselect. Support ns-resolution time stamps.
4068 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
4070 * xselect.c (wait_for_property_change, x_get_foreign_selection):
4071 Check for time stamp overflow, and support ns-resolution time stamps.
4073 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
4074 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
4075 (timeval_subtract): Remove; no longer needed.
4076 (XTflash, XTring_bell, x_wait_for_event):
4077 Port to ns-resolution time stamps. Don't assume time_t is signed.
4079 2012-06-22 Chong Yidong <cyd@gnu.org>
4081 * xdisp.c (x_consider_frame_title): Revert last change.
4083 2012-06-22 Eli Zaretskii <eliz@gnu.org>
4085 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
4086 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
4087 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
4088 staticidx goes up to 1597 out of 1600 = 0x640.)
4090 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
4092 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
4093 Otherwise, the umask might be mistakenly 0 while handling input signals.
4095 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
4097 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

4103 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
4104 access to `contents' member of Lisp_Vector objects with AREF and ASET

4360 code works fine either way, and efficiency is not a concern here,
4361 as the union type is for debugging, not for production.
4362 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
4363 Use an inline function on all platforms when using the union type,
4364 since this is simpler and 'static inline' can be used portably

4509 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
4510 would mishandle a string argument "Xc" if X was a multibyte

4593 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
4594 Use 'float' consistently, rather than 'float' in most places
4595 and 'double' in a couple of places.
4597 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4599 * xdisp.c (handle_stop): Detect whether we have overlay strings
4600 loaded by testing it->current.overlay_string_index to be
4601 non-negative, instead of checking whether n_overlay_strings is
4602 positive. (Bug#11587)
4604 2012-05-31 Chong Yidong <cyd@gnu.org>
4606 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
4608 * doc.c (Fsubstitute_command_keys): Doc fix.
4610 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4612 * search.c (search_buffer): Remove calls to
4613 r_alloc_inhibit_buffer_relocation, as it is now called by
4614 maybe_unify_char, which was the cause of relocation of buffer text
4617 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4619 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4620 for the duration of call to load_charset, to avoid problems with
4621 callers of maybe_unify_char that access buffer text through C
4624 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4625 decrement the inhibition flag, instead of just setting or
4628 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4630 Remove obsolete '#define static' cruft.
4631 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
4632 This #undef was "temporary" in 2000; it is no longer needed
4633 now that '#define static' has gone away.
4634 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4635 (gray_bitmap_bits): Remove; no longer needed.
4636 All uses replaced with definiens.
4637 * xterm.c: Include "bitmaps/gray.xbm".
4639 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4641 Clean up __executable_start, monstartup when --enable-profiling.
4642 The following changes affect the code only when profiling.
4643 * dispnew.c (__executable_start): Rename from safe_bcopy.
4644 Define only on platforms that need it.
4645 * emacs.c: Include <sys/gmon.h> when profiling.
4646 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
4647 (__executable_start): Remove decl, since lisp.h does it now.
4648 (safe_bcopy): Remove decl; no longer has that name.
4649 (main): Coalesce #if into single bit of code, for simplicity.
4650 Cast pointers to uintptr_t, since standard libraries want integers
4652 * lisp.h (__executable_start): New decl.
4654 2012-05-31 Glenn Morris <rgm@gnu.org>
4656 * image.c (Fimagemagick_types): Doc fix.
4658 2012-05-30 Jim Meyering <meyering@redhat.com>
4660 * callproc.c (Fcall_process_region): Include directory component
4661 in mkstemp error message (Bug#11586).
4663 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
4665 * alloc.c, lisp.h (make_pure_vector): Now static.
4667 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

4672 * data.c (Fdefalias): Purify definition, except for keymaps.
4673 (Qdefun): Move from eval.c.
4674 * lisp.h (Qdefun): Remove.
4675 * lread.c (read1): Tiny simplification.
4677 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4679 Do not create empty overlays with the evaporate property (Bug#9642).
4680 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4681 Bug#9642, but explicitly check that the buffer the overlay would
4682 be moved to is live and rearrange lines to make sure that errors
4683 will not put the overlay in an inconsistent state.
4684 (Fdelete_overlay): Cosmetics.
4686 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4688 * w32term.c (my_bring_window_to_top): New function.
4689 (x_raise_frame): Use handle returned by DeferWindowPos, which
4690 could be different from the original one.
4691 Call my_bring_window_to_top instead of my_set_foreground_window.
4694 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4695 by calling BringWindowToTop.
4697 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
4698 (WM_EMACS_END): Increase by one.
4700 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4702 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4703 This avoids undefined behavior that might cause the eassert
4704 to not catch an out-of-range value.
4706 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4708 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4709 Update dependencies.
4711 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4713 * bidi.c (bidi_mirror_char): Fix last change.
4715 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
4717 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
4718 when referring to sectname field in printf format.
4720 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4722 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4723 Only r_alloc_inhibit_buffer_relocation needed to be added;
4724 the others were already declared.
4726 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4727 before checking whether it's out of range. Put the check inside
4729 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4731 2012-05-27 Ken Brown <kbrown@cornell.edu>
4733 * callproc.c (Fcall_process): Restore a line that was accidentally
4734 commented out in the 2011-02-13 change (bug#11547).
4736 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4738 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4739 defined on ralloc.c.
4741 * buffer.c [REL_ALLOC]: Remove prototypes of
4742 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4743 they are now on lisp.h.
4745 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4747 * search.c (search_buffer): Use it to inhibit relocation of buffer
4748 text while re_search_2 is doing its job, because re_search_2 is
4749 passed C pointers to buffer text. (Bug#11519)
4751 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4754 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4755 state after an additional call to move_it_in_display_line_to, keep
4756 the values of it->max_ascent and it->max_descent found for the
4758 (pos_visible_p): Revert the comparison against bottom_y to what it
4759 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4762 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4764 Fix coding-related core dumps with gcc -ftrapv.
4765 The code was computing A - B, where A and B are pointers, and B is
4766 random garbage. This can lead to core dumps on platforms that
4767 have special pointer registers, and it also leads to core dumps on
4768 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4769 A - B only when B is initialized properly.
4770 * coding.c (coding_set_source, coding_set_destination): Return void.
4771 (coding_change_source, coding_change_destinations): New functions,
4772 with the old behaviors of coding_set_source and coding_set_destination.
4773 All callers that need an offset changed to use these new functions.
4775 2012-05-26 Glenn Morris <rgm@gnu.org>
4777 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4779 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4781 Extend mouse support on W32 text-mode console.
4782 * xdisp.c (draw_row_with_mouse_face):
4783 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4785 * w32console.c: Include window.h.
4786 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4788 (initialize_w32_display): Initialize mouse-highlight data.
4790 * w32inevt.c: Include termchar.h and window.h.
4791 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4792 moves, call note_mouse_highlight. If help_echo changed, call
4793 gen_help_event to produce help-echo message in the echo area.
4794 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4797 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4799 * lread.c (read1): Simplify slightly to avoid an overflow warning
4800 with GCC 4.7.0 on x86-64.
4802 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4804 * bidi.c (bidi_mirror_char): Revert last change: an int is
4805 definitely wide enough here.
4807 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4809 Fix integer width and related bugs (Bug#9874).
4810 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
4811 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
4812 (string_bytes, check_sblock, allocate_string_data):
4813 (compact_small_strings, Fmake_bool_vector, make_string)

4815 (make_string_from_bytes, make_specified_string)
4816 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
4817 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4819 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4820 (allocate_pseudovector):
4821 Use int, not EMACS_INT, where int is wide enough.
4822 (inhibit_garbage_collection, Fgarbage_collect):
4823 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4824 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4825 int might not be wide enough.
4826 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4827 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
4828 (bidi_at_paragraph_end, bidi_find_paragraph_start)
4829 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4830 (bidi_level_of_next_char, bidi_move_to_visually_next):
4831 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4832 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4833 (Fkill_buffer, Fset_buffer_major_mode)
4834 (advance_to_char_boundary, Fbuffer_swap_text)
4835 (Fset_buffer_multibyte, overlays_at, overlays_in)
4836 (overlay_touches_p, struct sortvec, record_overlay_string)
4837 (overlay_strings, recenter_overlay_lists)
4838 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4839 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4840 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4841 (Foverlay_recenter, last_overlay_modification_hooks_used)
4842 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4843 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4844 (validate_region): Omit unnecessary test for b <= e,
4845 since that's guaranteed by the previous test.
4846 (adjust_overlays_for_delete): Avoid pos + length overflow.
4847 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4848 (report_overlay_modification):
4849 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4850 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4851 Omit pointer cast, which isn't needed anyway, and doesn't work
4852 after the EMACS_INT -> ptrdiff_t change.
4853 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4854 * buffer.h: Adjust decls to match defn changes elsewhere.
4855 (struct buffer_text, struct buffer):

4857 Use EMACS_INT, not int, where int might not be wide enough.
4858 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
4859 not int, to avoid needless 32-bit limit on 64-bit hosts.
4860 (exec_byte_code): Use tighter memory-full test, one that checks
4861 for alloca overflow. Don't compute the address of the object just
4862 before an array, as that's not portable. Use EMACS_INT, not
4863 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4864 * callint.c (Fcall_interactively):
4865 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4866 * callproc.c (call_process_kill, Fcall_process):
4867 Don't assume pid_t fits into an Emacs fixnum.

4870 (call_process_cleanup, Fcall_process, delete_temp_file)
4871 (Fcall_process_region):
4872 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4873 (Fcall_process): Simplify handling of volatile integers.
4874 Use int, not EMACS_INT, where int will do.
4875 * casefiddle.c (casify_object, casify_region, operate_on_word)
4876 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4877 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4878 (casify_object): Avoid integer overflow when overallocating buffer.
4879 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4880 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4881 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4882 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4883 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4884 integers are now checked earlier. All uses replaced with XINT.
4886 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4887 For CCL_MapSingle, check that content and value are in int range.
4888 (ccl_driver, Fregister_code_conversion_map):
4889 Check that Vcode_version_map_vector is a vector.
4890 (resolve_symbol_ccl_program): Check that vector header is in range.
4891 Always copy the vector, so that we can check its contents reliably
4892 now rather than having to recheck each instruction as it's being
4893 executed. Check that vector words fit in 'int'.
4894 (ccl_get_compiled_code, Fregister_ccl_program)
4895 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4896 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4897 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4898 contents are in range.
4899 (Fccl_execute_on_string): Check that status is in range.
4900 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4901 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4902 Accept and return EMACS_INT, not int, because callers can pass values
4904 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4905 (multibyte_chars_in_text, parse_str_as_multibyte)
4906 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
4907 (str_as_unibyte, str_to_unibyte, string_count_byte8)
4908 (string_escape_byte8, Fget_byte):
4909 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4910 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4911 avoid mishandling large integers.
4912 * character.h: Adjust decls to match defn changes elsewhere.
4913 * charset.c (load_charset_map_from_file, find_charsets_in_text)

4915 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4916 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
4917 (load_charset_map_from_vector, Fdefine_charset_internal):
4918 Don't assume fixnum fits in int.
4919 (load_charset_map_from_vector, Fmap_charset_chars):
4920 Remove now-unnecessary CHECK_NATNUMs.
4921 (Fdefine_charset_internal): Check ranges here, more carefully.
4922 Don't rely on undefined behavior with signed left shift overflow.
4923 Don't assume unsigned int fits into fixnum, or that fixnum fits
4924 into unsigned int. Don't require max_code to be a valid fixnum;
4925 that's not true for gb10830 4-byte on a 32-bit host. Allow
4926 invalid_code to be a cons, for the same reason. Require code_offset
4927 to be a character. Avoid int overflow if max_char is close
4929 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4930 this is intended anyway and avoids some undefined behavior.
4931 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4932 INDEX_TO_CODE_POINT, as that's what it expects.
4933 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4934 * charset.h (DECODE_CHAR): Return int, not unsigned;
4935 this is what was intended anyway, and it avoids undefined behavior.
4936 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4937 integer-overflow issues.
4938 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4939 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4940 where the argument is EMACS_INT, and this behavior is not intended.
4941 * chartab.c (Fmake_char_table, Fset_char_table_range)
4942 (uniprop_get_decoder, uniprop_get_encoder):
4943 Don't assume fixnum fits in int.
4944 * cmds.c (move_point): New function, that does the gist of
4945 Fforward_char and Fbackward_char, but does so while checking
4946 for integer overflow more accurately.
4947 (Fforward_char, Fbackward_char): Use it.
4948 (Fforward_line, Fend_of_line, internal_self_insert)
4949 (internal_self_insert):
4950 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4951 Fix a FIXME, by checking for integer overflow when calculating
4952 target_clm and actual_clm.

4983 (get_translation, handle_composition_annotation, consume_chars):
4984 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4985 (consume_chars): Rewrite to not calculate an address outside buffer.
4986 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
4987 Don't access memory outside of the args array.
4988 (Fdefine_coding_system_internal): Check for charset-id overflow.
4989 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4990 result of ENCODE_CHAR.
4991 * coding.h: Adjust decls to match defn changes elsewhere.
4992 (struct coding_system):
4993 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

5729 * lread.c (init_obarray): Declare Qt and Qnil as special.
5731 2012-05-14 Glenn Morris <rgm@gnu.org>
5733 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
5734 Put "libexec" before "bin", for the sake of init_callproc_1.
5736 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5738 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
5740 * unexaix.c: Port to more-recent AIX compilers.
5741 (report_error, report_error_1, make_hdr, copy_sym)
5742 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
5743 Make arguments const char *, not char *, to avoid violations of C
5744 standard and to fix some AIX warnings reported by Gilles Pion.
5746 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5748 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
5749 already have overlays loaded.
5750 (handle_single_display_spec): Before returning without displaying
5751 fringe bitmap, synchronize the bidi iterator with the main display
5752 iterator, by calling iterate_out_of_display_property.
5753 (iterate_out_of_display_property): Detect buffer iteration by
5754 testing that it->string is a Lisp string.
5755 (get_next_display_element): When the current object is exhausted,
5756 and there's something on it->stack, call set_iterator_to_next to
5757 proceed with what's on the stack, instead of returning zero.
5758 (set_iterator_to_next): If called at the end of a Lisp string,
5759 proceed to consider_string_end without incrementing string
5760 position. Don't increment display vector index past the end of
5761 the display vector. (Bug#11417)
5762 (pos_visible_p): Don't report a position visible when move_it_to
5763 stopped at the last line of window, which happens to be scanned
5764 backwards by the bidi iteration. (Bug#11464)
5766 2012-05-14 Eli Zaretskii <eliz@gnu.org>
5768 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5769 and right-margin display specs even if the spec is invalid or we
5770 are on a TTY, and thus unable to display on the fringes.
5771 That's because the text with the property will not be displayed anyway,
5772 so we need to signal to the caller that this is a "replacing"
5773 display spec. This fixes display when the spec is invalid or we
5776 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5778 * unexaix.c (make_hdr): Fix typo in prototype.
5779 This bug broke the build on AIX. Problem reported by Gilles Pion.
5781 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5783 * keyboard.c (kbd_buffer_get_event): Read special events also in
5784 batch mode. (Bug#11415)
5786 2012-05-12 Glenn Morris <rgm@gnu.org>
5788 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5790 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5792 * lisp.mk (lisp): Add newcomment.elc.
5794 2012-05-12 Glenn Morris <rgm@gnu.org>
5796 * Makefile.in (MKDIR_P): New, set by configure.
5797 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5799 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5801 Remove unused function hourglass_started.
5802 * dispextern.h (hourglass_started):
5803 * w32fns.c (hourglass_started):
5804 * xdisp.c (hourglass_started): Remove.
5806 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5808 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5809 Update dependencies.
5811 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5813 * xgselect.c (xg_select): Put maxfds+1 into a var.
5814 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5816 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5818 2012-05-10 Dave Abrahams <dave@boostpro.com>
5820 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5821 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5823 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5825 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5826 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5827 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5828 Initialize xd_registered_buses.
5830 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5832 Untag more efficiently if USE_LSB_TAG.
5833 This is based on a proposal by YAMAMOTO Mitsuharu in
5834 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5835 For an admittedly artificial (nth 8000 longlist) benchmark on
5836 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5837 Emacs's overall text size by 1%.
5838 * lisp.h (XUNTAG): New macro.
5839 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5840 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5841 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5842 * eval.c (Fautoload):
5843 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5844 * frame.h (XFRAME): Use XUNTAG.
5846 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5847 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5848 Remove unportable assumptions about print widths of types like
5850 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5851 intptr_t when converting between pointer and integer, to avoid GCC
5852 warnings about wrong width.
5854 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5856 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5857 stack for each reader_thread, instead of defaulting to 8MB
5858 determined by the linker. This avoids failures in creating
5859 subprocesses on Windows 7, see the discussion in this thread:
5860 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5862 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5864 Fix up display of the *Minibuf-0* buffer in the mini window.
5865 * keyboard.c (read_char): Don't clear the echo area if there's no
5867 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5868 contents of *Minibuf-0*) if there's no message displayed in its stead.
5870 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5872 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5875 2012-05-06 Chong Yidong <cyd@gnu.org>
5877 * lisp.mk (lisp): Update.
5879 2012-05-05 Jim Meyering <meyering@redhat.com>
5881 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5883 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5885 * data.c (PUT_ERROR): New macro.
5886 (syms_of_data): Use it. Add new error type `user-error'.
5887 * undo.c (user_error): New function.
5888 (Fprimitive_undo): Use it.
5889 * print.c (print_error_message): Adjust print style for `user-error'.
5890 * keyboard.c (user_error): New function.
5891 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5893 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5895 Do not limit current-time-string to years 1000..9999.
5896 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5897 (Fcurrent_time_string): Support any year that is supported by the
5898 underlying localtime representation. Don't use asctime, as it
5899 has undefined behavior for years outside the range -999..9999.
5901 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5903 Fix race conditions involving setenv, gmtime, localtime, asctime.
5904 Without this fix, interrupts could mess up code that uses these
5905 nonreentrant functions, since setting TZ invalidates existing
5906 tm_zone or tzname values, and since most of these functions return
5907 pointers to static storage.
5908 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5909 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5910 Grow the critical sections to include not just invoking
5911 localtime/gmtime, but also accessing these functions' results
5912 including their tm_zone values if any, and any related TZ setting.
5913 (format_time_string): Last arg is now struct tm *, not struct tm **,
5914 so that the struct tm is saved in the critical section.
5915 All callers changed. Simplify allocation of initial buffer, partly
5916 motivated by the fact that memory allocation needs to be outside
5917 the critical section.
5919 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5921 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5922 with RESET_INTERVAL.
5924 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5925 Remove duplicated buffer name initialization.
5927 2012-05-02 Jim Meyering <jim@meyering.net>
5929 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5931 * xfns.c (x_window): Use xstrdup (Bug#11375).
5933 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5935 * xdisp.c (pos_visible_p): If already at a newline from the
5936 display string before the 'while' loop, don't walk back the glyphs
5937 from it3.glyph_row. Solves assertion violation when the display
5938 string begins with a newline (egg.el). (Bug#11367)
5940 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5942 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5945 2012-05-01 Glenn Morris <rgm@gnu.org>
5947 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5948 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5949 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5950 All were removed before 23.1.
5952 * dispnew.c: Remove HAVE_LIBNCURSES test;
5953 it is always true on relevant platforms.
5955 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5956 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5958 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5960 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5962 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5963 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5966 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5968 Do not avoid creating empty evaporating overlays (Bug#9642).
5969 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5970 That is, do not delete an evaporating overlay if it becomes
5971 empty after its bounds are adjusted to fit within its buffer.
5972 This fix caused other problems, and I'm reverting it until we get
5973 to the bottom of them.
5975 2012-04-27 Chong Yidong <cyd@gnu.org>
5977 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5979 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5981 * xdisp.c (pos_visible_p): If the window start position is beyond
5982 ZV, start the display from buffer beginning. Prevents assertion
5983 violation in init_iterator when the minibuffer window is scrolled
5986 * window.c (window_scroll_pixel_based): Likewise.
5988 2012-04-27 Chong Yidong <cyd@gnu.org>
5990 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5992 2012-04-27 Glenn Morris <rgm@gnu.org>
5994 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5995 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5997 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5999 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
6000 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
6002 2012-04-26 Eli Zaretskii <eliz@gnu.org>
6004 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
6005 display element, check also the underlying string or buffer
6006 character. (Bug#11341)
6008 * w32menu.c: Include w32heap.h.
6009 (add_menu_item): If the call to AppendMenuW (via
6010 unicode_append_menu) fails, disable Unicode menus only if we are
6011 running on Windows 9X/Me.
6013 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
6015 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
6016 (xgetint): Add missing shift for LSB tags.
6018 2012-04-24 Martin Rudalics <rudalics@gmx.at>
6020 * keyboard.c (read_char): Don't wipe echo area for select window
6021 events: These might get delayed via `mouse-autoselect-window'
6024 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
6026 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
6027 manipulation of :loaded-from data.
6029 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
6031 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
6032 now a cons (bug#11311).
6034 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
6036 Do not create empty overlays with the evaporate property (Bug#9642).
6037 * buffer.c (Fmove_overlay): Delete an evaporating overlay
6038 if it becomes empty after its bounds are adjusted to fit within
6039 its buffer. Without this fix, in a nonempty buffer (let ((o
6040 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
6041 yields an empty overlay that has the evaporate property, which is
6042 not supposed to happen.
6044 Fix minor GTK3 problems found by static checking.
6045 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
6046 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
6047 (struct _EmacsFixedClass, emacs_fixed_get_type):
6048 Move decls here from emacsgtkfixed.h, since they needn't be public.

6050 (emacs_fixed_class_init): Omit unused local.
6051 (emacs_fixed_child_type): Remove; unused.

6054 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
6055 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
6056 (EMACS_FIXED_GET_CLASS): Remove; unused.
6057 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
6059 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
6060 Problem reported by Juanma Barranquero for Windows -Wunused-function.
6062 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6064 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
6065 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
6066 (__malloc_size_t, __malloc_ptrdiff_t):
6067 Remove. All uses removed, replaced by the definiens if needed,
6068 since we can assume C89 or better now.
6069 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
6070 (protect_malloc_state, align, get_contiguous_space)
6071 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

6077 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
6078 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
6079 Define using prototypes, not old style.
6080 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
6081 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
6082 (align): Don't assume that signed integer overflow wraps around.
6083 Omit unused local var.
6084 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
6085 (_free_internal_nolock, memalign, mallochook, reallochook):
6086 Omit no-longer-needed casts.
6087 (valloc): Use getpagesize, not __getpagesize.
6088 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
6089 (struct hdr): The 'magic' member is now size_t, not unsigned long.
6091 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
6093 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
6095 Move functions from C to Lisp. Make non-blocking method calls
6096 the default. Implement further D-Bus standard interfaces.

6138 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6140 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
6141 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
6142 Do not assume ptrdiff_t is the same width as 'int'.
6144 * alloc.c: Handle unusual debugging option combinations.
6145 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
6146 since the two debugging options are incompatible.
6147 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
6149 (mem_init, mem_insert, mem_insert_fixup):
6150 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
6151 (NEED_MEM_INSERT): Remove; no longer needed.
6153 2012-04-22 Leo Liu <sdl.web@gmail.com>
6155 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
6157 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
6159 * sysdep.c [__FreeBSD__]: Minor cleanups.
6160 (list_system_processes, system_process_attributes) [__FreeBSD__]:
6161 Use Emacs indenting style more consistently. Avoid some casts.
6162 Use 'double' consistently rather than mixing 'float' and 'double'.
6164 2012-04-21 Eduard Wiebe <usenet@pusto.de>
6166 * sysdep.c (list_system_processes, system_process_attributes):
6167 Add implementation for FreeBSD (Bug#5243).
6169 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>
6171 * lisp.mk (lisp): Update.
6173 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
6175 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
6176 It is never used otherwise.
6178 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
6180 * print.c (print_preprocess): Only check print_depth if print-circle
6182 (print_object): Check for cycles even when print-circle is nil and
6183 print-gensym is t, but only check print_depth if print-circle is nil.
6185 2012-04-20 Chong Yidong <cyd@gnu.org>
6187 * process.c (wait_reading_process_output): If EIO occurs on a pty,

6201 row, return zero immediately.
6202 (try_cursor_movement): If inside continuation line, don't back up
6203 farther than the first row after the header line, if any.
6204 Don't consider the header-line row as "partially visible", even if
6205 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
6207 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

6242 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
6243 New extern decls, to avoid calling undeclared functions.
6244 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
6245 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
6246 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
6247 (NEED_MEM_INSERT): New macro.
6248 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
6249 Remove one incorrect comment and fix another.

6263 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
6264 Remove decls. This fixes an "It stinks!".
6266 * alloc.c (which_symbols): Fix alignment issue / type clash.
6268 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
6270 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

6283 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
6284 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
6285 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
6286 * s/netbsd.h, s/sol2-6.h:
6287 Remove definition of GC_MARK_STACK, since the default now works.
6288 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
6289 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
6290 no longer the default.
6291 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
6293 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
6295 * lread.c (lisp_file_lexically_bound_p):

6316 2012-04-11 Daniel Colascione <dancol@dancol.org>
6318 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
6319 against is gone. It's better to use vfork now so that when Cygwin
6320 gains a new, working vfork, we use it automatically (bug#10398).
6322 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

6338 (handle_interrupt): Use it.
6340 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
6342 * w32.c (w32_delayed_load): Record the full path of the library
6343 being loaded (bug#10424).
6345 2012-04-09 Glenn Morris <rgm@gnu.org>
6347 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
6348 not just in the obarray, before snarfing them. (Bug#11036)
6350 * Makefile.in ($(leimdir)/leim-list.el):
6351 Pass EMACS rather than BUILT_EMACS.

6360 Add convenience `GNUTLS_LOG2i' macro.
6362 * gnutls.c (gnutls_log_function2i): Convenience log function.
6363 (emacs_gnutls_read): Use new log functions,
6364 `gnutls_handshakes_tried' process member, and

6366 attempts per process (connection).
6368 2012-04-09 Chong Yidong <cyd@gnu.org>

6375 * minibuf.c (Fread_variable): Callers changed.
6377 2012-04-09 Eli Zaretskii <eliz@gnu.org>
6379 * xdisp.c (set_cursor_from_row): If the display string appears in
6380 the buffer at position that is closer to point than the position
6381 after the display string, display the cursor on the first glyph of
6382 the display string. Fixes cursor display when a 'display' text
6383 property immediately follows invisible text. (Bug#11094)
6385 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
6387 composite.c: use 'double' consistently
6388 * composite.c (get_composition_id): Use 'double' consistently
6389 instead of converting 'float' to 'double' and vice versa; this is
6390 easier to understand and avoids a GCC warning.
6392 2012-04-09 Glenn Morris <rgm@gnu.org>
6394 * Makefile.in: Generate leim-list with bootstrap-emacs, in
6395 preparation for dumping it with emacs. (Bug#4789)

6417 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
6418 (mark_memory): Mark Lisp_Objects only if pointers might hide in
6419 objects, as mark_maybe_pointer will catch them otherwise.
6420 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
6421 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
6423 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
6425 Fix typo that broke non-Windows builds.
6426 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
6428 2012-04-07 Eli Zaretskii <eliz@gnu.org>
6430 Support building on MS-Windows with libxml2.
6432 * makefile.w32-in (OBJ2): Add xml.$(O).

6436 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
6437 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
6438 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
6439 [!WINDOWSNT]: New macros.
6440 (init_libxml2_functions, libxml2_loaded_p): New functions.
6441 (parse_region): Call fn_xmlCheckVersion instead of using the macro
6442 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
6443 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
6444 Calls xmlCleanupParser only if libxml2 was loaded (or statically
6446 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
6447 Call init_libxml2_functions before calling libxml2 functions.
6448 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
6450 * emacs.c: Don't include libxml/parser.h.
6451 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
6452 xmlCleanupParser directly.
6454 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
6456 2012-04-07 Eli Zaretskii <eliz@gnu.org>

6464 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
6465 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
6466 about subtle differences between FETCH_CHAR* and STRING_CHAR*
6467 macros related to unification of CJK characters. For the details,
6468 see the discussion following the message here:
6469 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
6471 2012-04-04 Chong Yidong <cyd@gnu.org>
6473 * keyboard.c (Vdelayed_warnings_list): Doc fix.
6475 2012-04-01 Eli Zaretskii <eliz@gnu.org>
6477 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

6485 2012-03-31 Eli Zaretskii <eliz@gnu.org>
6487 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
6488 position we get to after a call to move_it_to fails the
6489 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
6490 only if we wind up in a string from display property. (Bug#11063)
6492 * window.c (Fdelete_other_windows_internal): Invalidate the row
6493 and column information about mouse highlight, so that redisplay
6494 restores it after reallocating the glyph matrices. (Bug#7464)
6496 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
6497 string comes from a `display' text property, use the buffer
6498 position of that property as if we actually saw that position in
6500 (move_it_by_lines): Remove the assertion that
6501 "it->current_x == 0 && it->hpos == 0" which can be legitimately
6502 violated when there's a before-string at the beginning of a line.
6505 2012-03-30 Eli Zaretskii <eliz@gnu.org>
6507 * xdisp.c (append_space_for_newline): If the default face was
6508 remapped, use the remapped face for the appended newline.
6509 (extend_face_to_end_of_line): Use the remapped default face for
6510 extending the face to the end of the line.
6511 (display_line): Call extend_face_to_end_of_line when the default
6512 face was remapped. (Bug#11068)
6514 2012-03-29 Eli Zaretskii <eliz@gnu.org>

6536 handle-select-window too (Bug#8996).
6538 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
6540 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
6542 2012-03-25 Kenichi Handa <handa@m17n.org>
6544 * dispextern.h (struct glyph): Change the bit length of
6545 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
6547 2012-03-24 Eli Zaretskii <eliz@gnu.org>
6549 * s/ms-w32.h (tzname): Include time.h before redirecting to
6550 _tzname. Fixes the MSVC build. (Bug#9960)

6554 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
6557 * xterm.c (XTread_socket): Only modify handling_signal if
6558 !SYNC_INPUT. (Bug#11080)
6560 2012-03-23 Eli Zaretskii <eliz@gnu.org>
6562 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
6563 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
6564 when fetching a multibyte character consumes more bytes than
6565 CHAR_BYTES returns, due to unification of CJK characters in
6566 string_char. (Bug#11073)
6568 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
6570 * process.c (wait_reading_process_output): Handle pty disconnect
6571 by refraining from sending oneself a SIGCHLD (bug#10933).

6582 2012-03-21 Chong Yidong <cyd@gnu.org>
6584 * xfaces.c (Vface_remapping_alist): Doc fix.
6586 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6588 * w32proc.c (Fw32_set_console_codepage)
6589 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

6600 it fit in a valid range (Bug#11003).
6602 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6604 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6605 that is not from display property, accept the row as a "cursor
6606 row" if one of the string's character has a non-nil `cursor'
6607 property. Fixes cursor positioning when there are newlines in
6608 overlay strings, e.g. in icomplete.el. (Bug#11035)
6610 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6612 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

6616 * eval.c (inhibit_lisp_code): Rename from
6617 inhibit_window_configuration_change_hook; move from window.c.
6619 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6620 * window.c (run_window_configuration_change_hook)
6621 (syms_of_window): Callers changed.
6623 2012-03-11 Chong Yidong <cyd@gnu.org>
6625 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6627 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).

6636 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6638 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6640 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6641 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6644 2012-03-03 Glenn Morris <rgm@gnu.org>
6646 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6648 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6650 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6651 position past the first glyph_row that ends at ZV. (Bug#10902)
6652 (redisplay_window, next_element_from_string): Fix typos in
6654 (redisplay_window): Pass to move_it_vertically the margin in
6655 pixels, not in screen lines.
6657 2012-03-02 Glenn Morris <rgm@gnu.org>
6659 * buffer.c (buffer-list-update-hook): Doc fix.
6661 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6663 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6664 push_it before setting up the iterator for the first overlay
6665 string, even if we have an empty string loaded.
6666 (next_overlay_string): If there's an empty string on the iterator
6667 stack, pop the stack. (Bug#10903)
6669 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6671 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6672 Suggested by Stefan Monnier in
6673 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6674 * alloc.c (widen_to_Lisp_Object): New static function.
6675 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6676 and widening them to Lisp_Objects. This would work even if
6677 USE_LSB_TAG is defined and wide integers are used, which might
6678 happen in a future version of Emacs.
6680 2012-02-25 Chong Yidong <cyd@gnu.org>
6682 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6685 * xselect.c (Fx_selection_exists_p): Doc fix.
6686 (x_clipboard_manager_save_all): Print an informative message
6687 before saving to clipboard manager.
6689 2012-02-24 Chong Yidong <cyd@gnu.org>
6691 * keyboard.c (process_special_events): Handle all X selection
6692 requests in kbd_buffer, not just the next one (Bug#8869).
6694 2012-02-23 Chong Yidong <cyd@gnu.org>
6696 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
6697 call when setting menu-bar-lines and tool-bar-lines parameters.
6698 (unwind_create_frame_1): New helper function.
6700 * window.c (inhibit_window_configuration_change_hook): New var.
6701 (run_window_configuration_change_hook): Obey it.
6702 (syms_of_window): Initialize it.
6704 2012-02-22 Chong Yidong <cyd@gnu.org>
6706 * xterm.c (x_draw_image_relief): Add missing type check for

6718 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
6719 when computing $valmask.
6721 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6722 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6723 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6724 It's useless in that case, and it can cause problems on hosts
6725 that allocate halves of EMACS_INT values separately.
6726 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6727 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6728 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6729 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6730 it avoids undefined behavior on hosts where shifting right by more
6731 than the word width has undefined behavior.
6733 2012-02-19 Chong Yidong <cyd@gnu.org>
6735 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
6736 (Funhandled_file_name_directory, Ffile_name_as_directory)

6755 2012-02-15 Chong Yidong <cyd@gnu.org>
6757 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

6776 as that creates a dangerous corner case.
6778 * window.c (Fdelete_window_internal): Invalidate the mouse
6779 highlight (Bug#9904).
6781 2012-02-12 Glenn Morris <rgm@gnu.org>

6811 2012-02-07 Chong Yidong <cyd@gnu.org>
6813 * buffer.c (Fbuffer_local_variables)
6814 (buffer_lisp_local_variables): Handle unbound vars correctly;
6815 don't let Qunbound leak into Lisp.
6817 2012-02-07 Glenn Morris <rgm@gnu.org>
6819 * image.c (Fimagemagick_types): Doc fix.
6821 * image.c (imagemagick-render-type): Change it from a lisp object

6854 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
6856 Handle overflow when computing char display width (Bug#9496).
6857 * character.c (char_width): Return EMACS_INT, not int.
6858 (char_width, c_string_width): Check for overflow when
6859 computing the width; this is possible now that individual
6860 characters can have unbounded width. Problem introduced
6861 by merge from Emacs 23 on 2012-01-19.
6863 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

7533 behave as if the cursor position were at the window margin.
7535 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
7536 and the cursor position is out of bounds, behave as if the cursor

7567 * dispnew.c (verify_row_hash): Call row_hash for computing the
7568 hash code of a row, instead of duplicating code from xdisp.c.
7570 * dispextern.h (row_hash): Add prototype.
7572 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

7677 Avoid some portability problems by eschewing 'extern inline' functions.
7678 The trivial performance wins aren't worth the portability hassles; see
7679 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
7681 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

7714 2011-11-07 Martin Rudalics <rudalics@gmx.at>
7716 * window.h: Declare delete_all_child_windows instead of

7729 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
7730 This is also needed for porting to any host where GC_MARK_STACK is
7731 not GC_MAKE_GCPROS_NOOPS.
7732 (which_symbols): Use it.
7734 2011-11-07 Kenichi Handa <handa@m17n.org>

7755 (window_box_width, window_box_left, window_box_left_offset)
7756 (window_box_right, window_box_right_offset): Declare extern.
7757 Otherwise, these inline functions do not conform to C99 and
7758 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7759 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7760 * intervals.c (adjust_intervals_for_insertion)
7761 (adjust_intervals_for_deletion): Now extern, because otherwise the
7762 extern inline functions 'offset_intervals' couldn't refer to it.
7763 (static_offset_intervals): Remove.
7764 (offset_intervals): Rewrite using the old contents of
7765 static_offset_intervals. The old version didn't conform to C99
7766 because an extern inline function contained a reference to an
7767 identifier with static linkage.

7789 (Fwindow_vscroll): Doc fix.
7790 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
7791 argument, since it makes no sense to pass a live window and for
7792 consistency with window-child.

7822 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
7823 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
7824 Move terminal->reference_count++ just before making the frame official

8079 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
8080 * editfns.c: Rewrite current-time-zone so that it invokes
8081 the equivalent of (format-time-string "%Z") to get the time zone name.
8082 This fixes a bug when the time zone name contains characters that
8083 need converting from the system time locale to Emacs internal format.
8084 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
8085 that patch fixed format-time-string to do the conversion, but
8086 I forgot to fix current-time-zone.
8087 (format_time_string): New function, containing most of
8088 what Fformat_time_string used to contain.

8096 * systime.h (tzname, timezone): Remove no-longer-used declarations.
8098 2011-10-19 Eli Zaretskii <eliz@gnu.org>
8100 * xdisp.c (start_display): If the character at POS is displayed
8101 via a display vector, reset IT->current.dpvec_index to zero.
8102 (try_window_reusing_current_matrix): If a line ends in a display
8103 vector or the next line starts in a display vector, continue
8104 redrawing the window even though the character position of
8105 start_row was reached.
8108 2011-10-18 Chong Yidong <cyd@gnu.org>
8110 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
8111 with nobreak-char-display too.

8115 Fix part 3 of bug#9771.
8116 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
8117 (bidi_resolve_neutral): Don't enter the expensive loop looking for
8118 non-neutral characters if the current character is a paragraph
8119 separator (a.k.a. Newline). This avoids running the same
8120 expensive loop twice, once when we consume the preceding newline
8121 and the other time when the line actually needs to be displayed.
8122 Avoid the loop when we see neutrals on the base embedding level
8123 following a character whose directionality is the same as the
8124 paragraph's. This avoids running the expensive loop when a line
8125 ends in a long sequence of neutrals, like control characters.
8126 Add assertion against STRONG_AL type. Slightly rearrange code
8127 that determines the type of a neutral given the first non-neutral
8129 (bidi_level_of_next_char): Set next_en_pos to zero when
8130 invalidating its info.
8132 2011-10-17 Eli Zaretskii <eliz@gnu.org>
8134 * xdisp.c (push_display_prop): Determine whether to record string
8135 or buffer position by IT->string, not by IT->method. Allow
8136 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
8137 (move_it_vertically_backward): Don't look for character position
8138 immediately after the newline when in a continuation line.
8141 2011-10-15 Martin Rudalics <rudalics@gmx.at>
8143 * window.c (coordinates_in_window): Rewrite and delabelize
8144 vertical border check. (Bug#5357) (Bug#9618)
8146 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
8148 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
8149 errors in XSetWindowBorder (bug#9310).
8151 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
8153 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
8154 avoid crash when xmalloc overrun checking is enabled.
8156 2011-10-13 Eli Zaretskii <eliz@gnu.org>
8158 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
8159 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
8160 cursor motion with <left> and <right> arrow keys.
8162 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
8163 some callers set that themselves.
8165 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8167 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
8168 display string and the previous row comes from the same string and
8169 is empty. (Bug#9739) (Bug#9738)
8171 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
8173 * doc.c (get_doc_string): Encode file name (bug#9735).
8175 2011-10-12 Eli Zaretskii <eliz@gnu.org>
8177 * bidi.c (bidi_level_of_next_char):
8178 * xdisp.c (get_visually_first_element): Remove old incorrect
8179 comments regarding the Unicode Line Separator character.
8181 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
8183 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
8185 * alloc.c (Fgc_status): Do not access beyond zombies array
8186 boundary if nzombies > MAX_ZOMBIES.
8187 * alloc.c (dump_zombies): Add missing format specifier.
8189 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
8191 * xdisp.c (set_cursor_from_row): Simplify conditionals,
8192 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
8194 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
8195 Some packages use them to denote characters with modifiers.
8197 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
8199 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
8200 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
8201 matching a pp-number. Rename parameter var to var1.
8203 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
8205 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
8207 2011-10-08 Glenn Morris <rgm@gnu.org>
8209 * callint.c (Fcall_interactively): Give a more explicit error for the
8210 'c' case with a non-character input. (Bug#8479)
8212 2011-10-08 Eli Zaretskii <eliz@gnu.org>
8214 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
8216 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
8217 lines that are hscrolled on the left.
8219 * dispnew.c (buffer_posn_from_coords): Account for a possible
8220 presence of header-line. (Bug#4426)
8222 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
8224 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
8225 Don't advertise functionality which we discourage or doesn't work.
8227 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
8229 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
8230 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
8231 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
8232 this makes Emacs dump core during garbage collection on rare
8233 occasions. sizeof is obviously inferior to offsetof here, so
8234 stick with offsetof.
8235 (GC_POINTER_ALIGNMENT): New macro.
8236 (mark_memory): Omit 3rd (offset) arg; caller changed.
8237 Don't assume EMACS_INT alignment is the same as pointer alignment.
8239 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
8241 * keyboard.c (read_key_sequence_remapped): New var.
8242 (read_key_sequence): Compute remapping in the right buffer.
8243 (command_loop_1): Use read_key_sequence's remapping directly.
8245 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
8247 * dired.c (file_name_completion): Don't expand file name.
8248 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
8249 before checking file name handler.
8251 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
8252 they've been requested explicitly (bug#9591).
8254 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
8256 * keymap.c (Fsingle_key_description): Use make_specified_string
8257 instead of build_string to build string from push_key_description.
8260 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8262 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
8263 This fixes a Y2038 bug on 64-bit hosts.
8264 * buffer.c (reset_buffer):
8265 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
8266 (Fclear_buffer_auto_save_failure):
8267 Use 0, not -1, to represent an unset failure time, since time_t
8268 might not be signed.
8270 Remove dependency on glibc malloc internals.
8271 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8272 Move back here from lisp.h, but with their new implementations.
8273 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8274 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
8275 * charset.c (charset_table_init): New static var.
8276 (syms_of_charset): Use it instead of xmalloc. This removes a
8277 dependency on glibc malloc internals. See Eli Zaretskii's comment in
8278 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
8279 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8280 Move back to alloc.c.
8281 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8282 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
8284 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
8286 * nsterm.m (windowDidResize): Call x_set_window_size only when
8287 ns_in_resize is true. Otherwise set pixelwidth/height and
8288 call change_frame_size (Bug#9628).
8290 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
8292 Port --enable-checking=all to Fedora 14 x86-64.
8293 * charset.c (syms_of_charset): Also account for glibc malloc's
8294 internal overhead when calculating the initial malloc maximum.
8296 Port --enable-checking=all to Fedora 14 x86.
8297 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8299 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
8300 (overrun_check_realloc, overrun_check_free):
8301 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
8302 That way, xmalloc returns a properly-aligned pointer even if
8303 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
8304 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
8305 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
8306 into account when calculating the initial malloc maximum.
8307 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
8308 Move here from alloc.c, so that charset.c can use it too.
8309 Properly align; the old code wasn't right for common 32-bit hosts
8310 when configured with --enable-checking=all.
8311 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
8312 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
8314 2011-09-29 Eli Zaretskii <eliz@gnu.org>
8316 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
8319 2011-09-28 Eli Zaretskii <eliz@gnu.org>
8321 * xdisp.c (compute_display_string_end): If there's no display
8322 string at CHARPOS, return -1.
8324 * bidi.c (bidi_fetch_char): When compute_display_string_end
8325 returns a negative value, treat the character as a normal
8326 character not covered by a display string. (Bug#9624)
8328 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
8330 * lread.c (Fread_from_string): Fix typo in docstring.
8332 2011-09-27 Eli Zaretskii <eliz@gnu.org>
8334 * xdisp.c (handle_invisible_prop): If invisible text ends on a
8335 newline, reseat the iterator instead of bidi-iterating there one
8336 character at a time. (Bug#9610)
8337 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
8338 TO_CHARPOS if the bidi iterator is at base embedding level.
8340 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
8342 * lread.c (readevalloop): Use correct code for NBSP.
8343 (read1): Likewise. (Bug#9608)
8345 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
8347 * dbusbind.c (Fdbus_register_signal): When service is not
8348 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
8350 2011-09-25 Glenn Morris <rgm@gnu.org>
8352 * buffer.c (truncate-lines): Doc fix.
8354 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
8356 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
8357 (Fset_window_next_buffers): Doc fix.
8359 2011-09-24 Glenn Morris <rgm@gnu.org>
8361 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
8363 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
8365 Fix minor problems found by static checking.
8366 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
8367 * indent.c (Fvertical_motion): Fix == vs = typo.
8369 2011-09-24 Eli Zaretskii <eliz@gnu.org>
8371 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
8372 Default value is now t. Doc fix.
8374 * indent.c (Fvertical_motion): Compute and apply the overshoot
8375 logic when moving up, not only when moving down. Fix the
8376 confusing name and values of the it_overshoot_expected variable;
8377 logic changes accordingly. (Bug#9254) (Bug#9549)
8379 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
8380 CHARPOS is covered by a display string which includes newlines.
8381 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
8382 is covered by a display string with embedded newlines.
8384 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
8386 * dbusbind.c (Fdbus_register_signal): Add match rule to
8387 Vdbus_registered_objects_table. (Bug#9581)
8388 (Fdbus_register_method, Vdbus_registered_objects_table):
8391 2011-09-24 Jim Meyering <meyering@redhat.com>
8393 do not ignore write error for any output size
8394 The previous change was incomplete.
8395 While it makes emacs --batch detect the vast majority of stdout
8396 write failures, errors were still ignored whenever the output size is
8397 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
8398 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
8399 && echo FAIL: ignored write error
8400 FAIL: ignored write error
8401 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
8402 && echo FAIL: ignored write error
8403 FAIL: ignored write error
8404 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
8406 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
8408 * emacs.c (Fkill_emacs): In noninteractive mode exit
8409 non-successfully if a write error occurred on stdout. (Bug#9574)
8411 2011-09-21 Eli Zaretskii <eliz@gnu.org>
8413 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
8416 * dispextern.h (struct it): Update the comment documenting what
8419 2011-09-20 Eli Zaretskii <eliz@gnu.org>
8421 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
8422 a display string, extend search for cursor position to end of row.
8423 (find_row_edges): If the row ends in a newline from a display
8424 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
8425 Handle the case of a display string with multiple newlines.
8426 (Fcurrent_bidi_paragraph_direction): Fix search for previous
8427 non-empty line. Fixes confusing cursor motion with arrow keys at
8428 the beginning of a line that starts with whitespace.

8437 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
8440 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8442 * xdisp.c (display_line): Record maximum and minimum buffer
8443 positions even if no glyphs were produced (e.g., by a zero-width
8444 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
8445 buffer positions that will be removed from the glyph row because
8447 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
8448 column is beyond frame width: don't subtract 1 "pixel" when
8449 computing width of the stretch.
8450 (reseat_at_next_visible_line_start): Undo the change made on
8451 2011-09-17 that saved paragraph information and restored it after
8452 the call to `reseat'. (Bug#9545)
8454 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8456 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
8457 and turn window cursor on if cleared (Bug#9415).

8470 Fix minor problem found by static checking.
8471 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
8472 initialized, to pacify gcc -Wuninitialized.
8474 * fileio.c: Report proper errno when syscall falls.
8475 (Finsert_file_contents): Save and restore errno,
8476 so that report_file_error outputs the correct diagnostic.
8477 (Fwrite_region) [CLASH_DETECTION]: Likewise.
8479 2011-09-18 Eli Zaretskii <eliz@gnu.org>
8481 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
8483 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8485 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
8486 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
8488 2011-09-17 Eli Zaretskii <eliz@gnu.org>
8490 * xdisp.c (reseat_at_next_visible_line_start): Keep information
8491 about the current paragraph and restore it after the call to reseat.
8493 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
8494 (bidi_find_paragraph_start): Search back for paragraph beginning
8495 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
8496 (bidi_move_to_visually_next): Only trigger paragraph-related
8497 computations when the last character is a newline or at EOB, not
8498 just any NEUTRAL_B. (Bug#9470)
8500 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
8501 truncated lines if point is covered by a display string. (Bug#9524)
8503 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
8505 * xselect.c: Relax test for outgoing X longs (Bug#9498).
8506 (cons_to_x_long): New function.
8507 (lisp_data_to_selection_data): Use it. Correct the test for
8508 short-versus-long data; it was negated. Break out of vector
8509 loop, for efficiency, when a long datum is discovered.
8511 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
8513 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
8515 2011-09-16 Eli Zaretskii <eliz@gnu.org>
8517 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
8518 GCC PR/17406) by declaring this function with external scope.
8520 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

8541 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
8542 This occurs when processing a multibyte format.
8543 Problem reported by Wolfgang Jenker.
8545 2011-09-15 Johan Bockgård <bojohan@gnu.org>
8547 * xdisp.c (try_cursor_movement): Only check for exact match if
8548 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
8550 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8552 Remove unused external symbols.
8553 * dispextern.h (calc_pixel_width_or_height): Remove decl.
8554 * xdisp.c (calc_pixel_width_or_height): Now static.
8555 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
8556 * indent.c (check_display_width):
8557 * w32term.c: Fix comment to match code.
8558 * xterm.c, xterm.h (x_catching_errors): Remove.
8560 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
8562 * xselect.c: Use signed conversions more consistently (Bug#9498).
8563 (selection_data_to_lisp_data): Assume incoming selection data are
8564 signed integers, not unsigned. This is to be consistent with
8565 outgoing selection data, which was modified to use signed integers
8566 in as part of the fix to Bug#9196 in response to Jan D.'s comment
8567 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
8568 expects long, not unsigned long.

8572 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
8573 computation of loop end. Reported by Johan Bockgård

8585 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8587 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
8589 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8591 * minibuf.c (Fread_from_minibuffer): Doc fix.
8593 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8595 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8596 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8598 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8600 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8601 value for non-existent files.
8603 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8605 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8606 set its "size" to -1. This will set the modtime_size field of
8607 the corresponding buffer to -1, which is what
8608 verify-visited-file-modtime expects for files that do not exist.
8611 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8613 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8615 * lisp.h: ... from here. push_key_description is no longer
8616 defined in keyboard.c, so its declaration should not be in
8617 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8618 logically belongs with push_key_description.
8620 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8622 * buffer.h: Include <sys/types.h> instead of <time.h>.
8623 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8624 Problem reported by Herbert J. Skuhra.
8626 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8628 * xml.c (parse_region): Make the parsing work for
8629 non-comment-starting XML files again (bug#9144).
8631 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8633 * image.c (gif_load): Fix calculation of bottom and right corner.
8636 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8638 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8639 redisplay in small windows.
8641 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8643 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8645 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8647 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8648 Operate on live windows only.
8650 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8652 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8654 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8656 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8657 only under bidi iteration.
8659 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8661 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8663 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8665 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8666 Without this fix, the command to link temacs failed due to an
8667 undefined symbol __builtin_isnan. This is because
8668 /usr/include/iso/math_c99.h #defines isnan(x) to
8669 __builtin_isnan(x), but the bundled gcc, which identifies itself
8670 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8672 * floatfns.c (isnan): #undef, and then #define to a clone of
8674 (Fisnan): Always define, since it's always available now.
8675 (syms_of_floatfns): Always define isnan at the Lisp level.
8677 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8679 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8681 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8683 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8684 The previous code assumed that file offsets (off_t values) fit in
8685 EMACS_INT variables, which is not true on typical 32-bit hosts.
8686 The code messed up by falsely reporting buffer overflow in cases
8687 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8688 when "big" contains more than 2**29 bytes, even though this
8689 inserts just one byte and does not overflow the buffer.
8690 (Finsert_file_contents): Store file offsets as off_t
8691 values, not as EMACS_INT values. Check for overflow when
8692 converting between EMACS_INT and off_t. When checking for
8693 buffer overflow or for overlap, take the offsets into account.
8694 Don't use EMACS_INT for small values where int suffices.
8695 When checking for overlap, fix a typo: ZV was used where
8696 ZV_BYTE was intended.
8697 (Fwrite_region): Don't assume off_t fits into 'long'.
8698 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8700 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8702 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8704 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8706 sprintf-related integer and memory overflow issues (Bug#9412).
8708 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8709 (esprintf, exprintf, evxprintf): New functions.
8710 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8711 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8712 (modify_event_symbol): Do not assume that the length of
8713 name_alist_or_stem is safe to alloca and fits in int.
8714 (Fexecute_extended_command): Likewise for function name and binding.
8715 (Frecursion_depth): Wrap around reliably on integer overflow.
8716 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8717 since some callers pass EMACS_INT values.
8718 (Fsingle_key_description): Don't crash if symbol name contains more
8719 than MAX_ALLOCA bytes.
8720 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8721 (get_minibuffer): Arg is now EMACS_INT, not int.
8722 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8723 (esprintf, exprintf, evxprintf): New decls.
8724 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8726 * dbusbind.c (signature_cat): New function.
8727 (xd_signature, Fdbus_register_signal):
8728 Do not overrun buffer; instead, report string overflow.
8730 * dispnew.c (add_window_display_history): Don't overrun buffer.
8731 Truncate instead; this is OK since it's just a log.
8733 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8734 even if the time zone offset is outlandishly large.
8735 Don't mishandle offset == INT_MIN.
8737 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8738 when creating daemon; the previous buffer-overflow check was incorrect.
8740 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8741 which has the guts of the old verror function.
8743 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8744 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8746 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8747 (font_unparse_xlfd): Don't blindly alloca long strings.
8748 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8749 fits in int, when using sprintf. Use single snprintf to count
8750 length of string rather than counting it via multiple sprintfs;
8751 that's simpler and more reliable.
8752 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8753 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8754 sprintf, in case result does not fit in int.
8756 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8757 (fontset_from_font): Print it.
8759 * frame.c (tty_frame_count): Now printmax_t, not int.
8760 (make_terminal_frame, set_term_frame_name): Print it.
8761 (x_report_frame_params): In X, window IDs are unsigned long,
8762 not signed long, so print them as unsigned.
8763 (validate_x_resource_name): Check for implausibly long names,
8764 and don't assume name length fits in 'int'.
8765 (x_get_resource_string): Don't blindly alloca invocation name;
8766 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8769 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8770 (xg_check_special_colors, xg_set_geometry):
8771 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8773 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8774 Use esprintf, not sprintf, in case result does not fit in int.
8776 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8777 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8778 it as a large positive number.
8779 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8780 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8782 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8783 in case result does not fit in int.
8785 * print.c (float_to_string): Detect width overflow more reliably.
8786 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8787 buffer overrun. Don't assume list length fits in 'int'. Treat
8788 print length of 0 as 0, not as infinity; to be consistent with other
8789 uses of print length in this function. Don't overflow print length
8790 index. Don't assume hash table size fits in 'long', or that
8791 vectorlike size fits in 'unsigned long'.
8793 * process.c (make_process): Use printmax_t, not int, to format
8794 process-name gensyms.
8796 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8798 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8799 to avoid potential buffer overrun.
8801 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8802 if X resource line is longer than 512 bytes.
8804 * xfns.c (x_window): Make sprintf buffer a bit bigger
8805 to avoid potential buffer overrun.
8807 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8809 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8811 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8813 Integer overflow fixes for scrolling, etc.
8814 Without these, Emacs silently mishandles large integers sometimes.
8815 For example, "C-u 4294967297 M-x recenter" was treated as if
8816 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8818 * xdisp.c (try_window_id): Check Emacs fixnum range before
8819 converting to 'int'.
8821 * window.c (window_scroll_line_based, Frecenter):
8822 Check that an Emacs fixnum is in range before assigning it to 'int'.
8823 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8824 values converted from Emacs fixnums.
8825 (Frecenter): Don't wrap around a line count if it is out of 'int'
8826 range; instead, treat it as an extreme value.
8827 (Fset_window_configuration, compare_window_configurations):
8828 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8830 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8831 that can exceed INT_MAX. Check that EMACS_INT value is in range
8832 before assigning it to the (possibly-narrower) index.
8833 (match_limit): Don't assume that a fixnum can fit in 'int'.
8835 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8838 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8839 (Fvertical_motion): Don't wrap around LINES values that don't fit
8840 in 'int'. Instead, treat them as extreme values. This is good
8841 enough for windows, which can't have more than INT_MAX lines anyway.
8843 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8845 * Require libxml/parser.h to avoid compilation warning.
8847 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8849 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8850 since this reportedly can destroy thread storage.
8852 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8854 * syntax.c (find_defun_start): Update all cache variables if
8855 exiting early (Bug#9401).
8857 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8859 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8861 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8862 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8863 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8865 * term.c (tty_append_glyph): New function.
8866 (produce_stretch_glyph): Static function and its prototype deleted.
8868 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8871 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8873 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8874 when checking :margin (Bug#9390).
8875 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8876 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8877 so that the name doesn't mislead. All uses changed.
8879 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8881 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8884 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8886 * xdisp.c (move_it_to): Don't bail out early when reaching
8887 position beyond to_charpos, if we are scanning backwards.
8888 (move_it_vertically_backward): When DY == 0, make sure we get to
8889 the first character in the line after the newline.
8891 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8893 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8894 (ccl_driver): Do not generate an out-of-range pointer.
8895 (Fccl_execute_on_string): Remove unnecessary check for
8896 integer overflow, noted by Stefan Monnier in
8897 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8898 Remove a FIXME that didn't need fixing.
8899 Simplify the newly-introduced buffer reallocation code.
8901 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8903 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8905 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8907 Integer and memory overflow issues (Bug#9196).
8909 * doc.c (get_doc_string): Rework so that
8910 get_doc_string_buffer_size is the actual buffer size, rather than
8911 being 1 less than the actual buffer size; this makes xpalloc more
8914 * image.c (x_allocate_bitmap_record, cache_image):
8915 * xselect.c (Fx_register_dnd_atom):
8916 Simplify previous changes by using xpalloc.
8918 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8919 since either will do and ptrdiff_t is convenient with xpalloc.
8921 * charset.c (charset_table_size)
8922 (struct charset_sort_data.priority): Now ptrdiff_t.
8923 (charset_compare): Don't overflow if priorities differ greatly.
8924 (Fsort_charsets): Don't assume list length fits in int.
8925 Check for size-calculation overflow when allocating sort data.
8926 (syms_of_charset): Allocate an initial charset table that is
8927 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8929 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8931 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8932 The actual value is always <= INT_MAX, and leaving it unsigned made
8933 overflow checking harder.
8935 * dispextern.h (struct glyph_matrix.rows_allocated)
8936 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8937 with xpalloc. The values are still always <= INT_MAX.
8939 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8941 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8942 (SAFE_NALLOCA): New macro.
8944 * region-cache.c (struct boundary.pos, find_cache_boundary)
8945 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8946 (set_cache_region, invalidate_region_cache)
8947 (revalidate_region_cache, know_region_cache, region_cache_forward)
8948 (region_cache_backward, pp_cache):
8949 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8950 so that ptrdiff_t * can be passed to xpalloc.
8951 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8952 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8953 (pp_cache): Don't assume cache_len fits in int.
8954 * region-cache.h: Adjust extern decls to match.
8956 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8957 EMACS_INT, since either will do, for xpalloc.
8959 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8960 (xnmalloc, xnrealloc, xpalloc): New functions.
8962 * bidi.c (bidi_shelve_header_size): New constant.
8963 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8964 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8966 * bidi.c (bidi_cache_shrink):
8967 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8969 Don't update size of array until after memory allocation succeeds,
8970 because xmalloc/xrealloc may not return.
8971 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8972 now that we have proper integer overflow checking.
8973 (record_overlay_string, overlay_strings): Catch overflows when
8974 calculating size of overlay_str_buf.
8976 * callproc.c (Fcall_process): Check for size overflow when
8977 calculating size of args2.
8978 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8979 Normally we prefer signed values, but sticking with ptrdiff_t would
8980 require adding more-complicated checks.
8982 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8983 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8984 Redo buffer-overflow calculations to avoid integer overflow.
8985 Add a FIXME comment where memory seems to be over-allocated.
8987 * character.c (Fstring): Check for size-calculation overflow.
8989 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8990 unnecessary integer overflow. Check for size overflow.
8991 (encode_coding_object): Don't update size until xmalloc succeeds.
8993 * composite.c (get_composition_id): Check for overflow in glyph
8994 length calculations.
8996 Integer and memory overflow fixes for display code.
8997 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8998 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8999 (scrolling_window): Check for overflow in size calculations.
9000 (line_draw_cost, realloc_glyph_pool, add_row_entry):
9001 Don't assume glyph table len fits in int.
9002 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
9003 (row_table_size): Now ptrdiff_t, not int.
9004 (scrolling_window): Avoid overflow in size calculations.
9005 Don't update size until allocation succeeds.
9006 * fns.c (concat): Check for overflow in size calculations.
9007 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
9008 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
9009 (NEXT_ALMOST_PRIME_LIMIT): New constant.
9011 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
9012 (get_doc_string): Check for size calculation overflow.
9013 Don't update size until allocation succeeds.
9014 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
9015 EMACS_INT, where ptrdiff_t will do.
9016 (Fsubstitute_command_keys): Check for string overflow.
9018 * editfns.c (set_time_zone_rule): Don't assume environment length
9020 (message_length): Now ptrdiff_t, not int.
9021 (Fmessage_box): Don't update size until allocation succeeds.
9022 Don't assume message length fits in int.
9023 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
9025 * emacs.c (main): Do not reallocate argv, since there is a null at
9026 the end that can be overwritten, and this way there's no need to
9027 worry about size-calculation overflow.
9028 (sort_args): Check for size-calculation overflow.
9030 * eval.c (init_eval_once, grow_specpdl): Don't update size until
9032 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
9034 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
9035 (x_set_scroll_bar_width, x_figure_window_size):
9036 Check for integer overflow.
9037 (x_set_alpha): Do not assume XINT fits in int.
9039 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
9040 This is for the members text_lines, text_cols, total_lines, total_cols,
9041 where the system imposes an 'int' limit.
9043 * fringe.c (Fdefine_fringe_bitmap):
9044 Don't update size until alloc works.
9046 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
9047 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
9049 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
9050 Check for size-calculation overflow.
9051 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
9052 do, as we prefer signed integers.
9053 (id_to_widget.max_size, id_to_widget.used)
9054 (xg_store_widget_in_map, xg_remove_widget_from_map)
9055 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
9056 (xg_remove_scroll_bar, xg_update_scrollbar_pos):

9106 (Fset_match_data): Don't assume list lengths fit in 'int'.
9108 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,

9156 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
9157 (X_LONG_MIN): New macros.
9158 Use them to make the following changes clearer.
9159 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
9160 This change doesn't affect the value now, but it may help remind
9161 future maintainers not to raise the value too much later.
9162 (SELECTION_QUANTUM): Remove, replacing with ...
9163 (selection_quantum): ... new function, which avoids overflow.
9165 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
9166 assumption that selection length fits in 'int'.

9183 Don't store size until memory allocation succeeds.
9184 (x_get_window_property): Plug memory leak on memory exhaustion.
9185 Don't double-block input; malloc is safe here. Don't assume 2**34
9186 - 4 fits in unsigned long. Add an xassert to check
9187 XGetWindowProperty overflow. Be more careful about overflow
9188 calculations, and distinguish size from memory overflow better.

9194 in the range -65535 through -1 fit in an X unsigned short.
9195 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
9196 result parameters unless successful. Rely on cons_to_unsigned
9197 to report problems with elements; the old code wasn't right anyway.
9198 (x_check_property_data): Check for int overflow; we cannot use
9199 a wider type due to X limits.
9200 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

9232 * lisp.h (hash_lookup, hash_put):
9233 * minibuf.c (Ftest_completion):
9234 Use ptrdiff_t for hash table indexes, not int (which is too
9235 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
9236 32-bit --with-wide-int hosts).

9269 (x_send_scroll_bar_event): Likewise. Check that the size does not
9270 exceed limits imposed by XClientMessageEvent, as well as the usual
9271 ptrdiff_t and size_t limits.
9273 * keyboard.c: Overflow, signedness and related fixes.
9274 (make_lispy_movement): Use same integer type in forward decl
9275 that is used in the definition.
9276 (read_key_sequence, keyremap_step):
9277 Change bufsize argument back to int, undoing my 2011-03-30 change.
9278 We prefer signed types, and int is wide enough here.
9279 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
9280 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
9281 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
9282 length, not size_t. Use ptrdiff_t for index, not int.
9283 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
9284 possibility of integer overflow.

9312 Prefer int to unsigned where either will do.
9313 (tiff_handler): New function, combining the cores of the
9314 old tiff_error_handler and tiff_warning_handler.
9315 This function is rewritten to use vsnprintf and thereby avoid
9316 stack buffer overflows. It uses only the features of vsnprintf
9317 that are common to both POSIX and native Microsoft.
9318 (tiff_error_handler, tiff_warning_handler): Use it.
9319 (tiff_load, gif_load, imagemagick_load_image):
9320 Don't assume :index value fits in 'int'.
9321 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

9323 the integer types that MagickCropImage accepts. Don't assume
9324 Vimagemagick_render_type has a nonnegative value. Don't assume
9325 size_t fits in 'long'.
9326 (gs_load): Use printmax_t to print the widest integers possible.

9344 accurately, and prefer exact match for point under bidi.
9345 Don't advance `row' beyond the last row of the window.
9347 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
9348 into disp_prop; all users changed.
9350 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

9366 positioning on the newline at EOL of R2L text within L2R
9367 paragraph, and vice versa.
9368 (try_cursor_movement): Check continued rows, in addition to
9369 continuation rows. Fixes unwarranted scroll when point enters a
9370 continued line of R2L text within an L2R paragraph, or vice versa.
9371 (cursor_row_p): Consider the case of point being equal to
9372 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
9373 from the end of a short line to the beginning of a continued line

9401 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
9402 instead of CHAR_TO_BYTE. Fixes a crash when a completion
9403 candidate is selected by the mouse, and that candidate has a
9404 composed character under the mouse.
9406 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
9407 coordinates reported by pos-visible-in-window-p for a composed

9422 * image.c (gif_load): Don't assume that each subimage has the same
9423 dimensions as the base image. Handle disposal method that is
9424 "undefined" by the gif spec (Bug#9335).
9426 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
9428 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

9433 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
9434 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
9435 from an Org mode buffer to a Speedbar frame.
9437 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
9438 a composition, take its buffer position from IT->cmp_it.charpos.
9439 Fixes cursor positioning at the beginning of a line that begins
9440 with a composed character.
9442 2011-08-18 Eli Zaretskii <eliz@gnu.org>
9444 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
9445 character bidirectional type, use STRONG_L instead. Fixes crashes
9446 in a buffer produced by `describe-categories'.
9448 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
9449 members before the level stack, so they would be saved and
9450 restored when copying iterator state. Fixes incorrect reordering
9451 around TABs covered by display properties.
9453 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

9523 2011-08-14 Eli Zaretskii <eliz@gnu.org>
9525 * xdisp.c (move_it_in_display_line_to): Don't invoke
9526 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
9527 ppos_it. Fixes vertical cursor motion when line beginning is
9528 covered by an image. (Bug#9296)
9530 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
9532 * nsterm.h (ns_run_ascript): Declare.
9533 (NSAPP_DATA2_RUNASSCRIPT): Define.
9535 * nsfns.m (as_script, as_result, as_status): New static variables.
9536 (ns_run_ascript): New function.
9537 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
9538 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
9539 the event loop. Get status from as_status (Bug#7276).
9541 * nsterm.m (sendEvent): If event is NSApplicationDefined and
9542 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
9543 the event loop (Bug#7276).
9545 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
9547 * gnutls.c (QCgnutls_bootprop_priority)
9548 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
9549 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
9550 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
9551 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
9552 (QCgnutls_bootprop_verify_hostname_error)
9553 (QCgnutls_bootprop_callbacks_verify): Rename from
9554 Qgnutls_bootprop_..., all uses changed.
9556 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
9559 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
9561 * xfaces.c (Qframe_set_background_mode): Now static.
9562 * dispextern.h (Qframe_set_background_mode): Remove decl.
9564 * process.c (Fnetwork_interface_info): Declare local only if needed.
9566 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
9568 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
9569 (Fnetwork_interface_list): Allocate in increments of bytes instead
9570 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
9571 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
9573 (struct ifflag_def): notrailers is smart on OSX.
9574 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9575 Get hardware address with getifaddrs if available.
9577 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9579 * xdisp.c (iterate_out_of_display_property): xassert that
9580 IT->position is set to within IT->object's boundaries. Break from
9581 the loop as soon as EOB is reached; avoids infloops in redisplay
9582 when IT->position is set up wrongly due to some bug.
9583 Set IT->current to match the bidi iterator unconditionally.
9584 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9585 entry. Force push_it to save on the stack the current
9586 buffer/string position, to be restored by pop_it. Fix flags in
9587 the iterator structure wrt the object coming from a display
9588 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9589 properties. (Bug#9284)
9591 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9593 * fontset.c (fontset_get_font_group): Add proper type checks.
9596 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9598 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
9599 and LC_VERSION_MIN_MACOSX.
9600 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9601 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9603 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9605 * xdisp.c (forward_to_next_line_start): Allow to use the
9606 no-display-properties-and-no-overlays under bidi display.
9607 Set disp_pos in the bidi iterator to avoid searches for display
9608 properties and overlays.
9610 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9612 * editfns.c (Fset_time_zone_rule): Document relationship with the
9615 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9616 the font entity extracted from the cache (Bug#8109).
9618 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9620 * composite.c (autocmp_chars): Don't reset point. That is done by
9621 restore_point_unwind (Bug#5984).
9623 2011-08-07 Juri Linkov <juri@jurta.org>
9625 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9626 to show the arg `TIME' instead of `TIMEVAL'.
9628 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9630 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9631 display property strides EOL and includes a newline, as in
9632 longlines-mode. (Bug#9254)
9633 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9634 word-wrap under bidirectional display. (Bug#9224)
9636 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9637 is non-zero, even if the data buffer is NULL. Fixes a crash in
9638 vertical-motion with longlines-mode. (Bug#9254)
9640 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9642 * bidi.c <bidi_cache_total_alloc>: Now static.
9643 (bidi_initialize): Initialize bidi_cache_total_alloc.
9645 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9648 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9649 amount allocated this far in `bidi_cache_total_alloc'.
9650 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9651 non-zero, only free the data buffer without restoring the cache
9652 contents. All callers changed.
9654 * dispextern.h (bidi_unshelve_cache): Update prototype.
9656 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9657 (move_it_in_display_line, move_it_to)
9658 (move_it_vertically_backward, move_it_by_lines): Replace the call
9659 to xfree to an equivalent call to bidi_unshelve_cache.
9660 (move_it_in_display_line_to): Fix logic of returning
9661 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9663 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9665 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9666 came from a string character with a `cursor' property. (Bug#9229)
9668 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9670 * Makefile.in (LIB_PTHREAD): New variable.
9671 (LIBES): Add LIB_PTHREAD (Bug#9216).
9673 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9674 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9676 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9678 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9680 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9682 * xterm.c (x_find_topmost_parent): New function.
9683 (x_set_frame_alpha): Find topmost parent window with
9684 x_find_topmost_parent and set the property there also (bug#9181).
9685 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9687 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9689 * callproc.c (Fcall_process): Avoid vfork clobbering
9690 the local vars buffer, coding_systems, current_dir.
9692 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9694 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9696 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9698 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9699 so that it is not optimized away.
9701 * xdisp.c (compute_display_string_pos): Remove unused local.
9703 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9705 Fix slow cursor motion and scrolling in large buffers with
9706 selective display, like Org Mode buffers. (Bug#9218)
9708 * dispextern.h (struct bidi_it): New member disp_prop_p.
9710 * xdisp.c: Remove one-slot cache of display string positions.
9711 (compute_display_string_pos): Accept an additional argument
9712 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9713 for a display string or property. If found, set DISP_PROP_P
9716 * bidi.c (bidi_fetch_char): Accept an additional argument
9717 DISP_PROP_P, and pass it to compute_display_string_pos.
9718 Only handle text covered by a display string if DISP_PROP_P is returned
9719 non-zero. All callers of bidi_fetch_char changed.
9721 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9723 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9725 2010-12-03 Don March <don@ohspite.net>
9727 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9728 last character M-[char] is translated to ESC [char] (bug#7541).
9730 2011-08-02 Kenichi Handa <handa@m17n.org>
9732 * lisp.h (uniprop_table): Extern it.
9734 * chartab.c (uniprop_table): Make it non-static.
9736 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9738 * xdisp.c (forward_to_next_line_start): Accept additional argument
9739 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9741 (reseat_at_next_visible_line_start): Use the bidi iterator state
9742 returned by forward_to_next_line_start to restore the state of
9743 it->bidi_it after backing up to previous newline. (Bug#9212)
9745 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9747 * regex.c (re_comp): Protoize.
9748 (re_exec): Fix return type.
9749 (regexec): Fix type of `ret'. (Bug#9203)
9751 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9753 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9754 This is needed if max-image-size is a floating-point number.
9756 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9758 * print.c (print_object): Print empty symbol as ##.
9760 * lread.c (read1): Read ## as empty symbol.
9762 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9764 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9765 setting frame foreground color (Bug#9175).
9766 (x_set_background_color): Likewise.
9768 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9769 contents (Bug#9176).
9770 (EmacsTooltip -init): Remove bezels and add shadows to
9773 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9774 or scroll bar (Bug#8470).
9776 * nsfont.m (nsfont_open): Remove assignment to voffset and
9777 unnecessary vars hshink, expand, hd, full_height, min_height.
9778 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9780 * nsterm.h (nsfont_info): Remove voffset field.
9782 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9784 Implement strike-through and overline on NextStep (Bug#8863).
9786 * nsfont.m (nsfont_open): Use underline position provided by font,
9787 instead of hard-coded value of 2.
9788 (nsfont_draw): Call ns_draw_text_decoration instead.
9790 * nsterm.h: Add declaration for ns_draw_text_decoration.
9792 * nsterm.m (ns_draw_text_decoration): New function for drawing
9793 underline, overline, and strike-through.
9794 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9795 ns_draw_text_decoration. Change treatment of cursor drawing to
9796 accommodate underlining, etc.
9798 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9800 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9803 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9805 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9806 Without this fix, if a signal arrives just after memory fills up,
9807 'malloc' might be invoked reentrantly.
9809 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9810 In other words, assume that every image size is allowed, on non-X
9811 hosts. This assumption is probably wrong, but it lets Emacs compile.
9813 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9815 * regex.c (re_iswctype): Convert return values to boolean.
9817 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9819 * xdisp.c (compute_display_string_pos): Don't use cached display
9820 string position if the buffer had its restriction changed.
9823 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9825 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9827 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9829 Integer signedness and overflow and related fixes. (Bug#9079)
9831 * bidi.c: Integer size and overflow fixes.
9832 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9833 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9834 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9835 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9836 (bidi_find_other_level_edge):
9837 Use ptrdiff_t instead of EMACS_INT where either will do.
9838 This works better on 32-bit hosts configured --with-wide-int.
9839 (bidi_cache_ensure_space): Check for size-calculation overflow.
9840 Use % rather than repeated addition, for better worst-case speed.
9841 Don't set bidi_cache_size until after xrealloc returns, because it
9843 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9844 (bidi_cache_ensure_space): Also check that the bidi cache size
9845 does not exceed that of the largest Lisp string or buffer. See Eli
9846 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9848 * alloc.c (__malloc_size_t): Remove.
9849 All uses replaced by size_t. See Andreas Schwab's note
9850 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9852 * image.c: Improve checking for integer overflow.
9853 (check_image_size): Assume that f is nonnull, since
9854 it is always nonnull in practice. This is one less thing to
9855 worry about when checking for integer overflow later.
9856 (x_check_image_size): New function, which checks for integer
9857 overflow issues inside X.
9858 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9859 This removes the need for a memory_full check.
9860 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9861 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9862 (xbm_read_bitmap_data): Change locals back to 'int', since
9863 their values must fit in 'int'.
9864 (xpm_load_image, png_load, tiff_load):
9865 Invoke x_create_x_image_and_pixmap earlier,
9866 to avoid much needless work if the image is too large.
9867 (tiff_load): Treat overly large images as if
9868 x_create_x_image_and_pixmap failed, not as malloc failures.
9869 (gs_load): Use x_check_image_size.
9871 * gtkutil.c: Omit integer casts.
9872 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9873 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9875 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9877 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9878 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9879 would wrongly return t on a 64-bit host.
9881 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9882 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9883 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9884 and therefore cause GCC to emit a bogus diagnostic in some cases.
9886 * image.c: Integer signedness and overflow and related fixes.
9887 This is not an exhaustive set of fixes, but it's time to
9888 record what I've got.
9889 (lookup_pixel_color, check_image_size): Remove redundant decls.
9890 (check_image_size): Don't assume that arbitrary EMACS_INT values
9891 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9892 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9893 (tiff_load, imagemagick_load_image):
9894 Check for overflow in size calculations.
9895 (x_create_x_image_and_pixmap): Remove unnecessary test for
9896 xmalloc returning NULL; that can't happen.
9897 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9898 (xpm_color_bucket): Use better integer hashing function.
9899 (xpm_cache_color): Don't possibly over-allocate memory.
9900 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9901 (gif_memory_source):
9902 Use ptrdiff_t, not int or size_t, to record sizes.
9903 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9904 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9905 either works, as we prefer signed integers.
9906 (tiff_read_from_memory, tiff_write_from_memory):
9907 Return tsize_t, not size_t, since that's what the TIFF API wants.
9908 (tiff_read_from_memory): Don't fail simply because the read would
9909 go past EOF; instead, return a short read.
9910 (tiff_load): Omit no-longer-needed casts.
9911 (Fimagemagick_types): Don't assume size fits into 'int'.
9913 Improve hashing quality when configured --with-wide-int.
9914 * fns.c (hash_string): New function, taken from sxhash_string.
9915 Do not discard information about ASCII character case; this
9916 discarding is no longer needed.
9917 (sxhash-string): Use it. Change sig to match it. Caller changed.
9918 * lisp.h: Declare it.
9919 * lread.c (hash_string): Remove, since we now use fns.c's version.
9920 The fns.c version returns a wider integer if --with-wide-int is
9921 specified, so this should help the quality of the hashing a bit.
9923 * emacs.c: Integer overflow minor fix.
9924 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9925 Define only if GNU_LINUX.
9926 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9928 * dispnew.c: Integer signedness and overflow fixes.
9929 Remove unnecessary forward decls, that were a maintenance hassle.
9930 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9932 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9933 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9934 (prepare_desired_row, line_draw_cost):
9935 Use int, not unsigned, where either works.
9936 (save_current_matrix, restore_current_matrix):
9937 Use ptrdiff_t, not size_t, where either works.
9938 (init_display): Check for overflow more accurately, and without
9939 relying on undefined behavior.
9941 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9942 Remove, replacing with the new symbols in lisp.h. All uses changed.
9943 * fileio.c (make_temp_name):
9944 * filelock.c (lock_file_1, lock_file):
9945 * xdisp.c (message_dolog):
9946 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9947 Use pMd etc. instead.
9948 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9949 replacing the pWIDE etc. symbols removed from editfns.c.
9951 * keyboard.h (num_input_events): Now uintmax_t.
9952 This is (very slightly) less likely to mess up due to wraparound.
9955 * buffer.c: Integer signedness fixes.
9956 (alloc_buffer_text, enlarge_buffer_text):
9957 Use ptrdiff_t rather than size_t when either will do, as we prefer
9960 * alloc.c: Integer signedness and overflow fixes.
9961 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9962 (__malloc_size_t): Default to size_t, not to int.
9963 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9964 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9965 Prefer ptrdiff_t to size_t when either would do, as we prefer
9967 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9968 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9969 Now const. Initialize with values that are in range even if char
9971 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9972 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9973 These functions do the right thing with sizes > 2**32.
9974 (check_depth): Now ptrdiff_t, not int.
9975 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9976 Adjust to new way of storing sizes. Check for size overflow bugs
9978 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9979 slightly wrong anyway, as it missed one instance of
9980 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9981 (refill_memory_reserve): Omit needless cast to size_t.
9982 (mark_object_loop_halt): Mark as externally visible.
9984 * xselect.c: Integer signedness and overflow fixes.
9985 (Fx_register_dnd_atom, x_handle_dnd_message):
9986 Use ptrdiff_t, not size_t, since we prefer signed.
9987 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9988 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9989 x_dnd_atoms_size and x_dnd_atoms_length.
9991 * doprnt.c: Prefer signed to unsigned when either works.
9993 * doprnt.c (doprnt):
9995 * xdisp.c (vmessage):
9996 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9997 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9998 prefer signed arithmetic to avoid comparison confusion.
9999 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
10000 but is a bit tricky.
10002 Assume freestanding C89 headers, string.h, stdlib.h.
10003 * data.c, doprnt.c, floatfns.c, print.c:
10004 Include float.h unconditionally.
10005 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
10006 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
10007 * regex.c: Likewise for stddef.h, string.h.
10008 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
10009 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
10010 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
10011 (STDC_HEADERS): Remove obsolete defines.
10012 * sysdep.c: Include limits.h unconditionally.
10014 Assume support for memcmp, memcpy, memmove, memset.
10015 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
10016 * regex.c (memcmp, memcpy):
10017 Remove; we assume C89 now.
10019 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
10020 (__malloc_safe_bcopy): Remove; no longer needed.
10022 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
10023 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
10024 well either way, and we prefer signed to unsigned.
10026 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
10028 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
10029 closes the connection while we're reading (bug#9182).
10031 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
10033 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
10034 are specified (Bug#9168).
10036 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
10038 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
10039 Found by GCC static checking and --with-wide-int on a 32-bit host.
10041 2011-07-25 Eli Zaretskii <eliz@gnu.org>
10043 * xdisp.c (compute_display_string_pos): Fix logic of caching
10044 previous display string position. Initialize cached_prev_pos to
10045 -1. Fixes slow-down at the beginning of a buffer.
10047 2011-07-24 Eli Zaretskii <eliz@gnu.org>
10049 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
10050 for attrs[LFACE_FONTSET_INDEX].
10052 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
10054 * xml.c (parse_region): Remove unused local
10055 that was recently introduced.
10057 2011-07-23 Eli Zaretskii <eliz@gnu.org>
10059 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
10060 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
10062 * xdisp.c (move_it_in_display_line_to): Record the best matching
10063 position for TO_CHARPOS while scanning the line, and restore it on
10064 exit if none of the characters scanned was an exact match.
10065 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
10066 when exact match is impossible due to invisible text, and the
10067 lines are truncated.
10069 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
10071 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
10074 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10076 Fix a significant slow-down of cursor motion with C-n, C-p,
10077 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
10078 auto-repeat under bidi redisplay in fontified buffers.
10079 * xdisp.c (compute_stop_pos_backwards): New function.
10080 (next_element_from_buffer): Call compute_stop_pos_backwards to
10081 find a suitable prev_stop when we find ourselves before
10083 (reseat): Don't look for prev_stop, as that could mean a very long
10085 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
10086 <cached_disp_overlay_modiff>: Cache for last found display string
10088 (compute_display_string_pos): Return the cached position if asked
10089 about the same buffer in the same area of character positions, and
10090 the buffer wasn't changed since the time the display string
10091 position was cached.
10093 2011-07-22 Eli Zaretskii <eliz@gnu.org>
10095 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
10096 is an integer, which is important for empty lines. (Bug#9149)
10098 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
10100 * frame.c (Fmodify_frame_parameters): In tty case, update the
10101 default face if necessary (Bug#4238).
10103 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
10105 * editfns.c (Fstring_to_char): No need to explain what a character
10106 is in the docstring (Bug#6576).
10108 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10110 * xml.c (parse_region): Make sure we always return a tree.
10112 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
10114 * xml.c (parse_region): If a document contains only comments,
10117 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
10119 * xml.c (make_dom): Return comments, too.
10121 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
10124 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
10125 and the surrounding thread.
10126 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
10127 rather than fgets, and retry after EINTR. Otherwise, 'emacs
10128 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
10130 * s/openbsd.h (BROKEN_SIGIO): Define.
10131 * unexelf.c (unexec) [__OpenBSD__]:
10132 Don't update the .mdebug section of the Alpha COFF symbol table.
10134 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
10136 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
10139 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
10141 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
10142 This fixes some race conditions on the permissions of any newly
10145 * alloc.c (valid_pointer_p): Use pipe, not open.
10146 This fixes some permissions issues when debugging.
10148 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
10149 If fchown fails to set both uid and gid, try to set just gid,
10150 as that is sometimes allowed. Adjust the file's mode to eliminate
10151 setuid or setgid bits that are inappropriate if fchown fails.
10153 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
10155 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
10156 to compare Lisp_Objects.
10157 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
10158 global_gnutls_log_level, don't mistake it for a Lisp_Object.
10159 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
10161 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
10163 * lread.c (read_integer): Unread even EOF character.
10164 (read1): Likewise. Properly record start position of symbol.
10166 * lread.c (read1): Read `#:' as empty uninterned symbol if no
10167 symbol character follows.
10169 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
10171 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
10172 This works around a problem with the previous change to Fcopy_file.
10173 Recent glibc declares fchown with __attribute__((warn_unused_result)),
10174 and without this change, GCC might complain about discarding
10175 fchown's return value.
10177 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
10179 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
10181 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
10183 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
10185 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
10187 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
10188 it's used from the C level.
10190 * process.c: Use the same condition for POLL_FOR_INPUT in both
10191 keyboard.c and process.c (bug#1858).
10193 2011-07-09 Lawrence Mitchell <wence@gmx.li>
10195 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
10196 (Fgnutls_boot): Use it.
10198 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
10200 * doc.c (Fsubstitute_command_keys): Revert last change.
10202 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
10204 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
10205 quotes the next character, and doesn't affect other longer
10206 sequences (bug#8935).
10208 * lread.c (syms_of_lread): Clarify that is isn't only
10209 `eval-buffer' and `eval-defun' that's affected by
10210 `lexical-binding' (bug#8460).
10212 2011-07-15 Eli Zaretskii <eliz@gnu.org>
10214 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
10215 bidi redisplay when a line includes both an image and is truncated.
10217 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
10219 Fix minor problems found by static checking.
10220 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
10221 (elsz): Now a signed constant, not a size_t var. We prefer signed
10222 types to unsigned, to avoid integer comparison confusion. Without
10223 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
10224 "cannot optimize loop, the loop counter may overflow", a symptom
10226 * indent.c (Fvertical_motion): Mark locals as initialized.
10227 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
10229 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
10231 * search.c (Fre_search_backward): Mention `case-fold-search' in
10232 all the re_search_* functions (bug#8138).
10234 * keyboard.c (Fopen_dribble_file): Document when the file is

10247 bidi_it->string.schars.
10248 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
10249 NULL (avoids a crash in bidi_paragraph_init).
10250 Initialize itb.string.lstring.
10251 (init_iterator): Call bidi_init_it only of a valid
10252 buffer position was specified. Initialize paragraph_embedding to
10254 (reseat_to_string): Initialize the bidi iterator.
10255 (display_string): If we need to ignore text properties of
10256 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
10257 original value of -1 will not work with bidi.)
10258 (compute_display_string_pos): First arg is now struct
10259 `text_pos *'; all callers changed. Support display properties on
10261 (compute_display_string_end): Support display properties on Lisp
10263 (init_iterator, reseat_1, reseat_to_string): Initialize the
10264 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
10265 when iterating on a string not from display properties).
10266 (compute_display_string_pos, compute_display_string_end):
10267 Fix calculation of the object to scan. Fixes an error when using
10269 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
10270 base_level_stop; instead, set base_level_stop to BEGV.
10271 Fixes crashes in vertical-motion.
10272 (next_element_from_buffer): Improve commentary for when
10273 the iterator is before prev_stop.
10274 (init_iterator): Initialize bidi_p from the default value of
10275 bidi-display-reordering, not from buffer-local value. Use the
10276 buffer-local value only if initializing for buffer iteration.
10277 (handle_invisible_prop): Support invisible properties on strings
10278 that are being bidi-reordered.
10279 (set_iterator_to_next): Support bidi reordering of C strings and
10281 (next_element_from_string): Support bidi reordering of Lisp
10283 (handle_stop_backwards): Support Lisp strings as well.
10284 (display_string): Support display of R2L glyph rows.
10285 Use IT_STRING_CHARPOS when displaying from a Lisp string.
10286 (init_iterator): Don't initialize it->bidi_p for strings
10288 (reseat_to_string): Initialize it->bidi_p for strings here.
10289 (next_element_from_string, next_element_from_c_string)
10290 (next_element_from_buffer): Add xassert's for correspondence
10291 between IT's object being iterated and it->bidi_it.string

10295 character that is not the first one in the visual order.
10296 (get_visually_first_element): New function, refactored from common
10297 parts of next_element_from_buffer, next_element_from_string, and
10298 next_element_from_c_string.
10299 (tool_bar_lines_needed, redisplay_tool_bar)
10300 (display_menu_bar): Force left-to-right direction. Add a FIXME
10301 comment for making that be controlled by a user option.
10302 (push_it, pop_it): Save and restore the state of the
10303 bidi iterator. Save and restore the bidi_p flag.
10304 (pop_it): Iterate out of display property for string iteration as
10306 (iterate_out_of_display_property): Support iteration over strings.
10307 (handle_single_display_spec): Set up it->bidi_it for iteration
10308 over a display string, and call bidi_init_it.
10309 (handle_single_display_spec, next_overlay_string)
10310 (get_overlay_strings_1, push_display_prop): Set up the bidi
10311 iterator for displaying display or overlay strings.
10312 (forward_to_next_line_start): Don't use the shortcut if
10314 (back_to_previous_visible_line_start): If handle_display_prop
10315 pushed the iterator stack, restore the internal state of the bidi
10316 iterator by calling bidi_pop_it same number of times.
10317 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
10318 and we are bidi-iterating, don't decrement the iterator position;
10319 instead, set the first_elt flag in the bidi iterator, to produce
10321 (reseat_1): Remove redundant setting of string_from_display_prop_p.
10322 (push_display_prop): xassert that we are iterating a buffer.
10323 (push_it, pop_it): Save and restore paragraph_embedding member.
10324 (handle_single_display_spec, next_overlay_string)
10325 (get_overlay_strings_1, reseat_1, reseat_to_string)
10326 (push_display_prop): Set up the `unibyte' member of bidi_it.string
10327 correctly. Don't assume unibyte strings are not bidi-reordered.
10328 (compute_display_string_pos)
10329 (compute_display_string_end): Fix handling the case of C string.
10330 (push_it, pop_it): Save and restore from_disp_prop_p.

10335 popping after iteration over a string that came from a display
10336 property. Fix a typo in popping stretch info. Add an assertion
10337 for verifying that the iterator position is in sync with the bidi
10339 (handle_single_display_spec, get_overlay_strings_1)
10340 (push_display_prop): Fix initialization of paragraph direction for
10341 string when that of the parent object is not yet determined.
10342 (reseat_1): Call bidi_init_it to resync the bidi
10343 iterator with IT's position. (Bug#7616)
10344 (find_row_edges): If ROW->start.pos gives position
10345 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
10346 (handle_stop, back_to_previous_visible_line_start, reseat_1):
10347 Reset the from_disp_prop_p flag.
10348 (SAVE_IT, RESTORE_IT): New macros.

10353 (try_scrolling, redisplay_window, display_line): Use them when
10354 saving a temporary copy of the iterator and restoring it back.
10355 (back_to_previous_visible_line_start, reseat_1)
10356 (init_iterator): Empty the bidi cache "stack".
10357 (move_it_in_display_line_to): If iterator ended up at
10358 EOL, but we never saw any buffer positions smaller than
10359 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
10360 motion in bidi-reordered lines.
10361 (move_it_in_display_line_to): Record prev_method and prev_pos
10362 immediately before the call to set_iterator_to_next. Fixes cursor
10363 motion in bidi-reordered lines with stretch glyphs and strings
10364 displayed in margins. (Bug#8133) (Bug#8867)
10365 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
10367 (pos_visible_p): Support positions in bidi-reordered lines.
10368 Save and restore bidi cache.
10370 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
10371 (bidi_paragraph_info): Delete unused struct.
10372 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
10373 (bidi_cache_start): New variable.
10374 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
10376 (bidi_cache_fetch_state, bidi_cache_search)
10377 (bidi_cache_find_level_change, bidi_cache_iterator_state)

10382 (bidi_fetch_char): Accept new argument STRING; all callers
10383 changed. Support iteration over a string. Support strings with
10384 display properties. Support unibyte strings. Fix the type of
10385 `len' according to what STRING_CHAR_AND_LENGTH expects.
10386 (bidi_paragraph_init, bidi_resolve_explicit_1)
10387 (bidi_resolve_explicit, bidi_resolve_weak)
10388 (bidi_level_of_next_char, bidi_move_to_visually_next):
10389 Support iteration over a string.
10390 (bidi_set_sor_type, bidi_resolve_explicit_1)
10391 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
10392 can now be zero (for strings); special values 0 and -1 were
10393 changed to -1 and -2, respectively.
10394 (bidi_char_at_pos): New function.
10395 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
10396 Call it instead of FETCH_MULTIBYTE_CHAR.

10406 (bidi_initialize): Initialize the bidi cache start stack pointer.
10407 (bidi_cache_ensure_space): New function, refactored from part of

10411 (bidi_count_bytes, bidi_char_at_pos): New functions.
10412 (bidi_cache_search): Don't assume bidi_cache_last_idx is

10481 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
10483 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
10484 The old code sometimes used this field without initializing it.
10486 * alloc.c (gc_sweep): Don't read past end of array.
10487 In theory, the old code could also have corrupted Emacs internals,
10488 though it'd be very unlikely.

10492 * character.c (Fcharacterp): Don't advertise optional ignored

10592 sigprocmask is portable only for single-threaded applications, and
10593 Emacs can be multi-threaded when it uses GTK.

10751 (clone_per_buffer_values): Don't assume that
10752 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
10753 This isn't true in general, and it's particularly not true
10754 if Emacs is configured with --with-wide-int.
10755 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
10756 New macros, used in the buffer.c change.

10792 Random fixes. E.g., (random) never returned negative values.
10793 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10794 subseconds part to the entropy, as that's a bit more random.
10795 Prefer signed to unsigned, since the signedness doesn't matter and
10796 in general we prefer signed. When given a limit, use a
10797 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10798 latter isn't right if USE_2_TAGS_FOR_INTS.
10799 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10800 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10810 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
10812 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
10813 This is more efficient than Ffile_directory_p and avoids a minor race.
10815 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
10817 * buffer.c (Foverlay_put): Say what the return value is
10820 * fileio.c (barf_or_query_if_file_exists): Check first if the file
10821 is a directory before asking whether to use the file name
10823 (barf_or_query_if_file_exists): Make the "File is a directory"
10824 error be more correct.
10826 * fns.c (Frequire): Remove the mention of the .gz files, since
10827 that's installation-specific, but keep the mention of
10828 `get-load-suffixes'.

10832 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

10840 Qgnutls_bootprop_verify_error (which is no longer used).
10842 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
10843 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
10844 Also (re)move comments that are misplaced or no longer relevant.
10846 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10848 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
10850 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
10852 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
10853 and background color parameters if they have been changed.

10945 * eval.c (struct backtrace): Simplify and port the data structure.
10946 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10947 signed bit field, as this assumption is not portable and it makes
10948 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10949 "char debug_on_exit : 1" as this is not portable either; instead,
10950 use the portable "unsigned int debug_on_exit : 1". Remove unused
10951 member evalargs. Remove obsolete comments about cc bombing out.

11141 (read1): Check for integer overflow in radices, and in
11142 read-circle numbers.

11186 on undefined behavior with wrong number of arguments.
11187 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
11188 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
11189 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
11190 since we're not interested in debugging glyphs with old libraries.
11191 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
11192 GCC 4.6.0's static checking.

11234 (x_session_initialize): Do not assume string length fits in int.
11236 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

11282 Don't assume pid_t and time_t fit in unsigned long.
11283 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
11284 (current_lock_owner): Prefer signed type for sizes.
11285 Use memcpy, not strncpy, where memcpy is what is really wanted.
11286 Don't assume (via atoi) that time_t and pid_t fit in int.
11287 Check for time_t and/or pid_t out of range, e.g., via a network share.
11288 Don't alloca where an auto var works fine.

11299 * coding.c (make_subsidiaries): Don't assume string length fits in int.
11301 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
11303 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
11304 We prefer signed integers, even for size calculations.
11306 * emacs.c: Don't assume string length fits in 'int'.
11307 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
11308 (main): Don't invoke strlen when not needed.
11310 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
11311 (XD_DEBUG_MESSAGE): Don't waste a byte.
11313 * callproc.c (getenv_internal_1, getenv_internal)
11314 (Fgetenv_internal):
11315 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
11317 * lread.c (invalid_syntax): Omit length argument.
11318 All uses changed. This doesn't fix a bug, but it simplifies the
11319 code away from its former Hollerith-constant appearance, and it's
11320 one less 'int' to worry about when looking at integer-overflow issues.
11321 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
11323 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
11324 This didn't break anything, but it didn't help either.
11325 It's confusing to put a bogus integer in a place where the actual
11326 value does not matter.
11327 (LIST_END_P): Remove unused macro and its bogus comment.
11328 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
11330 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
11331 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
11333 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
11334 We prefer signed types, and the value cannot exceed the EMACS_INT
11335 range anyway (because otherwise the length would not be representable).
11336 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
11337 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
11338 This avoids a GCC warning when WIDE_EMACS_INT.
11340 * indent.c (sane_tab_width): New function.
11341 (current_column, scan_for_column, Findent_to, position_indentation)
11342 (compute_motion): Use it. This is just for clarity.
11343 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
11345 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
11347 * lisp.h (lint_assume): New macro.
11348 * composite.c (composition_gstring_put_cache):
11349 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
11351 * editfns.c, insdel.c:
11352 Omit unnecessary forward decls, to simplify future changes.
11354 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
11356 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
11358 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
11359 Use much-faster test for byte-length change.
11360 Don't assume string byte-length fits in 'int'.
11361 Check that character arg fits in 'int'.
11362 (mapcar1): Declare byte as byte, for clarity.
11364 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
11366 * fns.c (concat): Catch string overflow earlier.
11367 Do not rely on integer wraparound.
11369 * dispextern.h (struct it.overlay_strings_charpos)
11370 (struct it.selective): Now EMACS_INT, not int.
11371 * xdisp.c (forward_to_next_line_start)
11372 (back_to_previous_visible_line_start)
11373 (reseat_at_next_visible_line_start, next_element_from_buffer):
11374 Don't arbitrarily truncate the value of 'selective' to int.
11376 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
11378 * composite.c: Don't truncate sizes to 'int'.
11379 (composition_gstring_p, composition_reseat_it)
11380 (composition_adjust_point): Use EMACS_INT, not int.
11381 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
11382 not EMACS_UINT, for indexes.
11384 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
11386 * buffer.c: Include <verify.h>.
11387 (struct sortvec.priority, struct sortstr.priority):
11388 Now EMACS_INT, not int.
11389 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
11390 (struct sortstr.size, record_overlay_string)
11391 (struct sortstrlist.size, struct sortlist.used):
11392 Don't truncate size to int.
11393 (record_overlay_string): Check for size-calculation overflow.
11394 (init_buffer_once): Check at compile-time, not run-time.
11396 2011-06-22 Jim Meyering <meyering@redhat.com>
11398 Don't leak an XBM-image-sized buffer
11399 * image.c (xbm_load): Free the image buffer after using it.
11401 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
11404 * composite.c (find_automatic_composition): Omit needless 'return 0;'
11405 that Sun C diagnosed.
11406 * fns.c (secure_hash): Fix pointer signedness issue.
11407 * intervals.c (static_offset_intervals): New function.
11408 (offset_intervals): Use it.
11410 2011-06-21 Leo Liu <sdl.web@gmail.com>
11413 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
11416 * fns.c (secure_hash): Rename from crypto_hash_function and change
11417 the first arg to accept symbols.
11418 (Fsecure_hash): New primitive.
11419 (syms_of_fns): New symbols.
11421 2011-06-20 Deniz Dogan <deniz@dogan.se>
11423 * process.c (Fset_process_buffer): Clarify return value in
11426 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
11428 * dispnew.c (add_window_display_history): Use BVAR.
11430 * xdisp.c (debug_method_add): Use BVAR.
11431 (check_window_end, dump_glyph_matrix, dump_glyph)
11432 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
11434 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
11437 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
11438 check till after the cache is created in init_frame_faces.
11440 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
11442 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
11444 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
11446 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
11447 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
11448 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
11450 Improve buffer-overflow checking (Bug#8873).
11451 * fileio.c (Finsert_file_contents):
11452 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
11453 Remove the old (too-loose) buffer overflow checks.
11454 They weren't needed, since make_gap checks for buffer overflow.
11455 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
11456 The old code merely checked for Emacs fixnum overflow, and relied
11457 on undefined (wraparound) behavior. The new code avoids undefined
11458 behavior, and also checks for ptrdiff_t and/or size_t overflow.
11460 * editfns.c (Finsert_char): Don't dump core with very negative counts.
11461 Tune. Don't use wider integers than needed. Don't use alloca.
11462 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
11464 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
11466 * insdel.c, lisp.h (buffer_overflow): New function.
11467 (insert_from_buffer_1, replace_range, replace_range_2):
11468 * insdel.c (make_gap_larger):
11469 * editfns.c (Finsert_char):
11470 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
11472 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
11474 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
11476 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
11478 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
11479 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
11481 * fileio.c: Don't assume EMACS_INT fits in off_t.
11482 (emacs_lseek): New static function.
11483 (Finsert_file_contents, Fwrite_region): Use it.
11484 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
11486 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
11488 * fns.c: Don't overflow int when computing a list length.
11489 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
11490 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
11491 truncation on 64-bit hosts. Check for QUIT every
11492 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
11493 faster and is responsive enough.
11494 (Flength): Report an error instead of overflowing an integer.
11495 (Fsafe_length): Return a float if the value is not representable
11496 as a fixnum. This shouldn't happen except in contrived situations.
11497 (Fnthcdr, Fsort): Don't assume list length fits in int.
11498 (Fcopy_sequence): Don't assume vector length fits in int.
11500 * alloc.c: Check that resized vectors' lengths fit in fixnums.
11501 (header_size, word_size): New constants.
11502 (allocate_vectorlike): Don't check size overflow here.
11503 (allocate_vector): Check it here instead, since this is the only
11504 caller of allocate_vectorlike that could cause overflow.
11505 Check that the new vector's length is representable as a fixnum.
11507 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
11508 The previous code was bogus. For example, next_almost_prime (32)
11509 returned 39, which is undesirable as it is a multiple of 3; and
11510 next_almost_prime (24) returned 25, which is a multiple of 5 so
11511 why was the code bothering to check for multiples of 7?
11513 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
11515 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
11517 Variadic C functions now count arguments with ptrdiff_t.
11518 This partly undoes my 2011-03-30 change, which replaced int with size_t.
11519 Back then I didn't know that the Emacs coding style prefers signed int.
11520 Also, in the meantime I found a few more instances where arguments
11521 were being counted with int, which may truncate counts on 64-bit
11522 machines, or EMACS_INT, which may be unnecessarily wide.
11523 * lisp.h (struct Lisp_Subr.function.aMANY)
11524 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
11525 Arg counts are now ptrdiff_t, not size_t.
11526 All variadic functions and their callers changed accordingly.
11527 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
11528 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
11529 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
11530 * callint.c (Fcall_interactively): Check arg count for overflow,
11531 to avoid potential buffer overrun. Use signed char, not 'int',
11532 for 'varies' array, so that we needn't bother to check its size
11533 calculation for overflow.
11534 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
11535 * eval.c (apply_lambda):
11536 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
11537 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
11538 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
11540 * callint.c (Fcall_interactively): Don't use index var as event count.
11542 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
11543 * mem-limits.h (SIZE): Remove; no longer used.
11545 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
11547 Remove unnecessary casts.
11548 * xterm.c (x_term_init):
11549 * xfns.c (x_set_border_pixel):
11550 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
11551 These aren't needed now that we assume ANSI C.
11553 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
11554 It's more likely to cause problems (due to unsigned overflow)
11557 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
11559 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
11561 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
11563 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
11565 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
11567 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
11569 GLYPH_CODE_FACE returns EMACS_INT, not int.
11570 * dispextern.h (merge_faces):
11571 * xfaces.c (merge_faces):
11572 * xdisp.c (get_next_display_element, next_element_from_display_vector):
11573 Don't assume EMACS_INT fits in int.
11575 * character.h (CHAR_VALID_P): Remove unused parameter.
11576 * fontset.c, lisp.h, xdisp.c: All uses changed.
11578 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11580 * fns.c (concat): Minor tuning based on overflow analysis.
11581 This doesn't fix any bugs. Use int to hold character, instead
11582 of constantly refetching from Emacs object. Use XFASTINT, not
11583 XINT, for value known to be a character. Don't bother comparing
11584 a single byte to 0400, as it's always less.
11586 * floatfns.c (Fexpt):
11587 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11589 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11592 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11594 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11595 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11596 incorrectly succeed when S was a string, because 4294967386 was
11597 truncated before it was used.
11599 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11600 Otherwise, an out-of-range integer could cause undefined behavior
11603 * composite.c: Use int, not EMACS_INT, for characters.
11604 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11605 EMACS_INT, for values that are known to be in character range.
11606 This doesn't fix any bugs but is the usual style inside Emacs and
11607 may generate better code on 32-bit machines.
11609 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11610 This is for reasons similar to the recent CHAR_STRING fix.
11611 * charset.c (Fencode_char): Check that character arg is actually
11612 a character. Pass an int to ENCODE_CHAR.
11613 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11614 wider than 'int', as a compile-time check to prevent future regressions
11617 * character.c (char_string): Remove unnecessary casts.
11619 Make sure a 64-bit char is never passed to CHAR_STRING.
11620 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11621 by silently ignoring the top 32 bits, allowing some values
11622 that were far too large to be valid characters.
11623 * character.h: Include <verify.h>.
11624 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11625 arguments are no wider than unsigned, as a compile-time check
11626 to prevent future regressions in this area.
11628 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11629 (Fsubst_char_in_region):
11631 * xdisp.c (decode_mode_spec_coding):
11632 Adjust to CHAR_STRING's new requirement.
11633 * editfns.c (Finsert_char, Fsubst_char_in_region):
11634 * fns.c (concat): Check that character args are actually
11635 characters. Without this test, these functions did the wrong
11636 thing with wildly out-of-range values on 64-bit hosts.
11638 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11639 These casts should not be needed on 32-bit hosts, either.
11640 * keyboard.c (read_char):
11641 * lread.c (Fload): Remove casts to unsigned.
11643 * lisp.h (UNSIGNED_CMP): New macro.
11644 This fixes comparison bugs on 64-bit hosts.
11645 (ASCII_CHAR_P): Use it.
11646 * casefiddle.c (casify_object):
11647 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11648 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11649 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11650 * dispextern.h (FACE_FROM_ID):
11651 * keyboard.c (read_char): Use UNSIGNED_CMP.
11653 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11654 not to EMACS_INT, to avoid GCC warning.
11656 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11658 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11659 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11660 isn't needed on 32-bit machines.
11662 * buffer.c (Fgenerate_new_buffer_name):
11663 Use EMACS_INT for count, not int.
11664 (advance_to_char_boundary): Return EMACS_INT, not int.
11666 * data.c (Qcompiled_function): Now static.
11668 * window.c (window_body_lines): Now static.
11670 * image.c (gif_load): Rename local to avoid shadowing.
11672 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11673 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11674 * alloc.c (make_save_value): Integer argument is now of type
11675 ptrdiff_t, not int.
11676 (mark_object): Use ptrdiff_t, not int.
11677 * lisp.h (pD): New macro.
11678 * print.c (print_object): Use it.
11680 * alloc.c: Use EMACS_INT, not int, to count objects.
11681 (total_conses, total_markers, total_symbols, total_vector_size)
11682 (total_free_conses, total_free_markers, total_free_symbols)
11683 (total_free_floats, total_floats, total_free_intervals)
11684 (total_intervals, total_strings, total_free_strings):
11685 Now EMACS_INT, not int. All uses changed.
11686 (Fgarbage_collect): Compute overall total using a double, so that
11687 integer overflow is less likely to be a problem. Check for overflow
11688 when converting back to an integer.
11689 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
11690 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
11691 These were 'int' variables that could overflow on 64-bit hosts;
11692 they were never used, so remove them instead of repairing them.
11693 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
11694 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
11695 Previously, this ceilinged at INT_MAX, but that doesn't work on
11697 (allocate_pseudovector): Don't use EMACS_INT when int would do.
11699 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
11700 (allocate_vectorlike): Check for ptrdiff_t overflow.
11701 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
11702 when a (possibly-narrower) signed value would do just as well.
11703 We prefer using signed arithmetic, to avoid comparison confusion.
11705 * alloc.c: Catch some string size overflows that we were missing.
11706 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
11707 for convenience in STRING_BYTES_MAX.
11708 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11709 The definition here is exact; the one in lisp.h was approximate.
11710 (allocate_string_data): Check for string overflow. This catches
11711 some instances we weren't catching before. Also, it catches
11712 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11713 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11714 and ptrdiff_t and EMACS_INT are both 64 bits.
11716 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11717 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
11718 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
11720 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
11722 * alloc.c (Fmake_string): Check for out-of-range init.
11724 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
11726 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
11728 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
11730 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
11731 xg_get_default_scrollbar_width.
11733 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
11734 (int_gtk_range_get_value): Move to the scroll bar part of the file.
11735 (style_changed_cb): Call update_theme_scrollbar_width and call
11736 x_set_scroll_bar_default_width and xg_frame_set_char_size for
11737 all frames (Bug#8505).
11738 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).

12188 Fframe_first_window and Fset_frame_selected_window to window.h.
12190 * window.h: Move EXFUNS for Fframe_root_window,
12191 Fframe_first_window and Fset_frame_selected_window here from

12218 code. Minor doc-string fixes.
12220 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
12222 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
12223 Do not assume that spare memory exists; that assumption is valid
12224 only if SYSTEM_MALLOC.
12225 (LARGE_REQUEST): New macro, so that the issue of large requests
12226 is separated from the issue of spare memory.
12228 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
12230 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

12256 New error handlers.
12257 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
12258 Obey Vx_select_enable_clipboard_manager. Catch errors in
12259 x_clipboard_manager_save (Bug#8779).
12260 (Vx_select_enable_clipboard_manager): New variable.
12261 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
12263 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
12265 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
12267 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12269 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
12270 in the current matrix if keep_current_p is non-zero.

12274 * bidi.c (bidi_level_of_next_char): Fix last change.
12276 2011-06-03 Eli Zaretskii <eliz@gnu.org>
12278 Support bidi reordering of text covered by display properties.
12280 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
12281 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
12282 (bidi_cache_search, bidi_cache_iterator_state)
12283 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12284 (bidi_level_of_next_char, bidi_move_to_visually_next):
12285 Support character positions inside a run of characters covered by a
12287 (bidi_paragraph_init, bidi_resolve_explicit_1)
12288 (bidi_level_of_next_char): Call bidi_fetch_char and
12289 bidi_fetch_char_advance instead of FETCH_CHAR and
12290 FETCH_CHAR_ADVANCE.

12292 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
12294 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
12295 instead of using explicit *_CHAR codes.
12296 (bidi_resolve_explicit, bidi_resolve_weak):
12297 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
12298 bidirectional text is supported only in multibyte buffers.
12299 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
12300 it to initialize the frame_window_p member of struct bidi_it.
12301 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
12302 (bidi_resolve_explicit, bidi_resolve_weak)

12304 bidi_it->nchars is non-positive.
12305 (bidi_level_of_next_char): Don't try to lookup the cache for the
12306 next/previous character if nothing is cached there yet, or if we
12307 were just reseat()'ed to a new position.
12309 * xdisp.c (set_cursor_from_row): Set start and stop points
12310 according to the row's direction when priming the loop that looks
12311 for the glyph on which to display cursor.
12312 (single_display_spec_intangible_p): Function deleted.
12313 (display_prop_intangible_p): Reimplement to call
12314 handle_display_spec instead of single_display_spec_intangible_p.
12315 Accept 3 additional arguments needed by handle_display_spec.
12316 This fixes incorrect cursor motion across display property with complex
12317 values: lists, `(when COND...)' forms, etc.
12318 (single_display_spec_string_p): Support property values that are
12319 lists with the argument STRING its top-level element.
12320 (display_prop_string_p): Fix the condition for processing a
12321 property that is a list to be consistent with handle_display_spec.
12322 (handle_display_spec): New function, refactored from the
12323 last portion of handle_display_prop.
12324 (compute_display_string_pos): Accept additional argument
12325 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
12326 value of a `display' property is a "replacing spec".
12327 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
12328 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
12329 the display property, but just return a value indicating whether
12330 the display property will replace the characters it covers.
12331 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
12332 frame_window_p members of struct bidi_it.
12333 (compute_display_string_pos, compute_display_string_end):
12335 (push_it): Accept second argument POSITION, where pop_it should
12336 jump to continue iteration.
12337 (reseat_1): Initialize bidi_it.disp_pos.
12339 * keyboard.c (adjust_point_for_property): Adjust the call to
12340 display_prop_intangible_p to its new signature.
12342 * dispextern.h (struct bidi_it): New member frame_window_p.
12343 (bidi_init_it): Update prototypes.
12344 (display_prop_intangible_p): Update prototype.
12345 (compute_display_string_pos, compute_display_string_end):
12346 Declare prototypes.
12347 (struct bidi_it): New members nchars and disp_pos. ch_len is now
12350 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
12352 Malloc failure behavior now depends on size of allocation.
12353 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
12354 * lisp.h: Change signatures accordingly.
12355 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
12356 All callers changed. (Bug#8762)
12358 * gnutls.c: Use Emacs's memory allocators.
12359 Without this change, the gnutls library would invoke malloc etc.
12360 directly, which causes problems on non-SYNC_INPUT hosts, and which
12361 runs afoul of improving memory_full behavior. (Bug#8761)
12362 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
12363 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
12364 xfree instead of the default malloc, realloc, free.
12365 (Fgnutls_boot): No need to check for memory allocation failure,
12366 since xmalloc does that for us.
12368 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
12369 * category.c (hash_get_category_set):
12370 * ccl.c (ccl_driver):
12371 * charset.c (Fdefine_charset_internal):

12382 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
12383 (Fsxhash, Fgethash, Fputhash, Fmaphash):
12384 * image.c (make_image, search_image_cache, lookup_image)
12385 (xpm_put_color_table_h):
12386 * lisp.h (struct Lisp_Hash_Table):
12387 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
12388 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
12389 for hashes and hash indexes, instead of 'unsigned' and 'int'.
12390 * alloc.c (allocate_vectorlike):
12391 Check for overflow in vector size calculations.
12392 * ccl.c (ccl_driver):
12393 Check for overflow when converting EMACS_INT to int.
12394 * fns.c, image.c: Remove unnecessary static decls that would otherwise
12395 need to be updated by these changes.
12396 * fns.c (make_hash_table, maybe_resize_hash_table):
12397 Check for integer overflow with large hash tables.
12398 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
12399 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
12400 (SXHASH_REDUCE): New macro.
12401 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
12402 Use it instead of discarding useful hash info with large hash values.
12403 (sxhash_float): New function.
12404 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
12405 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
12406 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
12407 Rewrite to use FIXNUM_BITS, as this simplifies things.
12408 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
12409 Adjust signatures to match updated version of code.
12410 (consing_since_gc): Now EMACS_INT, since a single hash table can
12411 use more than INT_MAX bytes.
12413 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
12415 Make it possible to build with GCC-4.6+ -O2 -flto.
12417 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
12419 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
12421 * minibuf.c (get_minibuffer, read_minibuf_unwind):
12422 Call minibuffer-inactive-mode.
12424 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
12426 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
12427 Update dependencies.
12429 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12431 * data.c (init_data): Remove code for UTS, this system is not
12434 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12436 Don't force ./temacs to start in terminal mode.
12438 * frame.c (make_initial_frame): Initialize faces in all cases, not
12439 only when CANNOT_DUMP is defined.
12440 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
12442 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12444 * dispnew.c (add_window_display_history): Use const for the string
12445 pointer. Remove declaration, not needed.
12447 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12449 Use 'inline', not 'INLINE'.
12450 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
12451 * alloc.c, fontset.c (INLINE): Remove.
12452 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
12453 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
12454 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
12455 * gmalloc.c (register_heapinfo): Use inline unconditionally.
12456 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
12458 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
12460 Make it possible to run ./temacs.
12462 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
12463 syms_of_callproc does the same thing. Remove test for
12464 "initialized", do it in the caller.
12465 * emacs.c (main): Avoid calling set_initial_environment when dumping.
12467 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
12469 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
12470 (read_minibuf): Use get_minibuffer.
12471 (syms_of_minibuf): Use DEFSYM.
12472 (Qmetadata): New var.
12473 * data.c (Qbuffer): Don't make it static.
12474 (syms_of_data): Use DEFSYM.
12476 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
12478 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
12479 (CCL_CODE_MIN): New macro.
12481 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
12483 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
12485 * eval.c (Qdebug): Now static.
12486 * lisp.h (Qdebug): Remove decl. This reverts a part of the
12487 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
12488 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
12490 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12492 * image.c: Various fixes to ImageMagick code comments.
12493 (Fimagemagick_types): Doc fix.
12495 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
12497 Minor fixes prompted by GCC 4.6.0 warnings.
12499 * xselect.c (converted_selections, conversion_fail_tag): Now static.
12501 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
12502 (x_clipboard_manager_save_all): Move extern decl to ...
12503 * xterm.h: ... here, so that it can be checked for consistency.
12505 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
12507 * xselect.c (x_clipboard_manager_save_frame)
12508 (x_clipboard_manager_save_all): New functions.
12509 (Fx_clipboard_manager_save): Lisp function deleted.
12511 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
12512 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
12514 * xterm.h: Update prototype.
12516 2011-05-28 William Xu <william.xwl@gmail.com>
12518 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
12519 exiting (Bug#8239).
12521 2011-05-28 Jim Meyering <meyering@redhat.com>
12523 Avoid a sign-extension bug in crypto_hash_function.
12524 * fns.c (to_uchar): Define.
12525 (crypto_hash_function): Use it to convert some newly-signed
12526 variables to unsigned, to avoid sign-extension bugs. For example,
12527 without this change, (md5 "truc") would evaluate to
12528 45723a2aff78ff4fff7fff1114760e62 rather than the expected
12529 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
12530 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
12532 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12534 Integer overflow fixes.
12536 * dbusbind.c: Serial number integer overflow fixes.
12537 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
12538 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
12539 to hold a serial number that is too large for a fixnum.
12540 (Fdbus_method_return_internal, Fdbus_method_error_internal):
12541 Check for serial numbers out of range. Decode any serial number
12542 that was so large that it became a float. (Bug#8722)
12544 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
12545 (Fdbus_call_method, Fdbus_call_method_asynchronously):
12546 Use XFASTINT rather than XUINT when numbers are nonnegative.
12547 (xd_append_arg, Fdbus_method_return_internal):
12548 (Fdbus_method_error_internal): Likewise. Also, for unsigned
12549 arguments, check that Lisp number is nonnegative, rather than
12550 silently wrapping negative numbers around. (Bug#8722)
12551 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
12554 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
12556 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
12558 ccl: Add integer overflow checks.
12559 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
12560 (IN_INT_RANGE): New macros.
12561 (ccl_driver): Use them to check for integer overflow when
12562 decoding a CCL program. Many of the new checks are whether XINT (x)
12563 fits in int; it doesn't always, on 64-bit hosts. The new version
12564 doesn't catch all possible integer overflows, but it's an
12565 improvement. (Bug#8719)
12567 * alloc.c (make_event_array): Use XINT, not XUINT.
12568 There's no need for unsigned here.
12570 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
12571 This follows up to the 2011-05-06 change that substituted uintptr_t
12572 for EMACS_INT. This case wasn't caught back then.
12574 Rework Fformat to avoid integer overflow issues.
12575 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12576 now (part of C89). Include <verify.h>.
12577 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12578 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12579 (Fformat): Avoid the prepass trying to compute sizes; it was only
12580 approximate and thus did not catch overflow reliably. Instead, walk
12581 through the format just once, formatting and computing sizes as we go,
12582 checking for integer overflow at every step, and allocating a larger
12583 buffer as needed. Keep track separately whether the format is
12584 multibyte. Keep only the most-recently calculated precision, rather
12585 than them all. Record whether each argument has been converted to
12586 string. Use EMACS_INT, not int, for byte and char and arg counts.
12587 Support field widths and precisions larger than INT_MAX. Avoid
12588 sprintf's undefined behavior with conversion specifications such as %#d
12589 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12590 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12591 formatting out-of-range floating point numbers with int
12592 formats. (Bug#8668)
12594 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12596 * data.c: Avoid integer truncation in expressions involving floats.
12597 * data.c: Include <intprops.h>.
12598 (arith_driver): When there's an integer overflow in an expression
12599 involving floating point, convert the integers to floating point
12600 so that the resulting value does not suffer from catastrophic
12601 integer truncation. For example, on a 64-bit host (* 4
12602 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12603 Do not rely on undefined behavior after integer overflow.
12605 merge count_size_as_multibyte, parse_str_to_multibyte
12606 * character.c, character.h (count_size_as_multibyte):
12607 Rename from parse_str_to_multibyte; all uses changed.
12608 Check for integer overflow.
12609 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12610 since it's now a duplicate of the other. This is more of
12611 a character than a buffer op, so better that it's in character.c.
12612 * fns.c, print.c: Adjust to above changes.
12614 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12616 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12618 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12620 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12621 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12622 (x_clipboard_manager_save): Now static.
12623 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12625 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12626 (crypto_hash_function): Now static.
12627 Fix pointer signedness problems. Avoid unnecessary initializations.
12629 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12631 * termhooks.h (Vselection_alist): Make it terminal-local.
12633 * terminal.c (create_terminal): Initialize it.
12635 * xselect.c: Support for clipboard managers.
12636 (Vselection_alist): Move to termhooks.h as terminal-local var.
12637 (LOCAL_SELECTION): New macro.
12638 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12639 (symbol_to_x_atom): Remove gratuitous arg.
12640 (x_handle_selection_request, lisp_data_to_selection_data)
12641 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12642 (x_own_selection, x_get_local_selection, x_convert_selection):
12643 New arg, specifying work frame. Use terminal-local Vselection_alist.
12644 (some_frame_on_display): Delete unused function.
12645 (Fx_own_selection_internal, Fx_get_selection_internal)
12646 (Fx_disown_selection_internal, Fx_selection_owner_p)
12647 (Fx_selection_exists_p): New optional frame arg.
12648 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12649 (x_handle_selection_clear): Don't treat other terminals with the
12650 same keyboard specially. Use the terminal-local Vselection_alist.
12651 (x_clear_frame_selections): Use Frun_hook_with_args.
12653 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12655 * xterm.h: Add support for those atoms.
12657 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12659 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12660 (converted_selections, conversion_fail_tag): New global variables.
12661 (x_selection_request_lisp_error): Free the above.
12662 (x_get_local_selection): Remove unnecessary code.
12663 (x_reply_selection_request): Args changed; handle arbitrary array
12664 of converted selections stored in converted_selections.
12665 Separate the XChangeProperty and SelectionNotify steps.
12666 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12667 (x_convert_selection): New function.
12668 (x_handle_selection_event): Simplify.
12669 (x_get_foreign_selection): Don't ignore incoming requests while
12670 waiting for an answer; this will fail when we implement
12671 SAVE_TARGETS, and seems unnecessary anyway.
12672 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12673 (Vx_sent_selection_functions): Doc fix.
12675 2011-05-26 Leo Liu <sdl.web@gmail.com>
12677 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12679 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12681 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12683 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12684 for fringe update if it has periodic bitmap.
12685 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12686 and fringe_bitmap_periodic_p.
12688 * fringe.c (get_fringe_bitmap_data): New function.
12689 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12690 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12691 row. Mark glyph row for fringe update if periodicity changed.
12693 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12694 for fringe update unless it has periodic bitmap.
12696 2011-05-25 Kenichi Handa <handa@m17n.org>
12698 * xdisp.c (get_next_display_element): Set correct it->face_id for
12699 a static composition.
12701 2011-05-24 Leo Liu <sdl.web@gmail.com>
12704 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12706 * fns.c (crypto_hash_function, Fsha1): New function.
12707 (Fmd5): Use crypto_hash_function.
12708 (syms_of_fns): Add Ssha1.
12710 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12712 * gnutls.c: Remove unused macros.
12713 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12714 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12715 Remove macros that are defined and never used.
12716 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12718 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12720 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12721 (Fx_get_selection_internal): Minor cleanup.
12722 (Fx_own_selection_internal): Rename arguments for consistency with
12725 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12727 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12729 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12731 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12733 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12735 * dispnew.c (scrolling_window): Don't exclude the case that the
12736 last enabled row in the desired matrix touches the bottom boundary.
12738 2011-05-21 Glenn Morris <rgm@gnu.org>
12740 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12741 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12742 and add some more files.
12744 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12746 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12747 report_file_error introduced by the change from 2011-05-07.
12749 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12751 * systime.h (Time): Define only if emacs is defined.
12752 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12753 where the include path doesn't have X11/X.h by default. See
12754 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12756 2011-05-20 Kenichi Handa <handa@m17n.org>
12758 * composite.c (find_automatic_composition): Fix previous change.
12760 2011-05-20 Glenn Morris <rgm@gnu.org>
12762 * lisp.mk: New file, split from Makefile.in.
12763 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12764 (shortlisp): Remove.
12765 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12767 2011-05-19 Glenn Morris <rgm@gnu.org>
12769 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12770 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12771 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12772 (lisp): Set the order to that of loadup.el.
12773 (shortlisp): Make it a copy of $lisp.
12774 (SOME_MACHINE_LISP): Remove.
12775 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12776 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12778 2011-05-18 Kenichi Handa <handa@m17n.org>
12780 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12781 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12782 (find_automatic_composition): Mostly rewrite for efficiency.
12784 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12786 * makefile.w32-in: Update dependencies.
12788 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12790 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12791 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12793 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12795 Fix some integer overflow issues, such as string length overflow.
12797 * insdel.c (count_size_as_multibyte): Check for string overflow.
12799 * character.c (lisp_string_width): Check for string overflow.
12800 Use EMACS_INT, not int, for string indexes and lengths; in
12801 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12802 the resulting string length overflows an EMACS_INT; instead,
12803 report a string overflow if no precision given. When checking for
12804 precision exhaustion, use a check that cannot possibly have
12805 integer overflow. (Bug#8675)
12806 * character.h (lisp_string_width): Adjust to new signature.
12808 * alloc.c (string_overflow): New function.
12809 (Fmake_string): Use it. This doesn't change behavior, but saves
12810 a few bytes and will simplify future changes.
12811 * character.c (string_escape_byte8): Likewise.
12812 * lisp.h (string_overflow): New decl.
12814 Fixups, following up to the user-interface timestamp change.
12815 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12816 for UI timestamps, instead of unsigned long.
12817 * msdos.c (mouse_get_pos): Likewise.
12818 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12819 * w32gui.h (Time): Define by including "systime.h" rather than by
12820 declaring it ourselves. (Bug#8664)
12822 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12823 * image.c (clear_image_cache): Likewise.
12825 * term.c (term_mouse_position): Don't assume time_t wraparound.
12827 Be more systematic about user-interface timestamps.
12828 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12829 and sometimes 'EMACS_UINT', to represent these timestamps.
12830 This change causes it to use 'Time' uniformly, as that's what X uses.
12831 This makes the code easier to follow, and makes it easier to catch
12832 integer overflow bugs such as Bug#8664.
12833 * frame.c (Fmouse_position, Fmouse_pixel_position):
12834 Use Time, not unsigned long, for user-interface timestamps.
12835 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12836 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12837 * keyboard.h (last_event_timestamp): Likewise.
12838 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12839 * menu.h (xmenu_show): Likewise.
12840 * term.c (term_mouse_position): Likewise.
12841 * termhooks.h (struct input_event.timestamp): Likewise.
12842 (struct terminal.mouse_position_hook): Likewise.
12843 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12844 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12845 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12846 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12847 what it was before.
12848 * menu.h, termhooks.h: Include "systime.h", for Time.
12850 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12851 Don't assume that the difference between two unsigned long values
12852 can fit into an integer. At this point, we know button_down_time
12853 <= event->timestamp, so the difference must be nonnegative, so
12854 there's no need to cast the result if double-click-time is
12855 nonnegative, as it should be; check that it's nonnegative, just in
12856 case. This bug is triggered when events are more than 2**31 ms
12857 apart (about 25 days). (Bug#8664)
12859 * xselect.c (last_event_timestamp): Remove duplicate decl.
12860 (x_own_selection): Remove needless cast to unsigned long.
12862 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12863 that always fit in int. Use a sentinel instead of a counter, to
12864 avoid a temp and to allay GCC's concerns about possible int overflow.
12865 * frame.h (struct frame): Use int for menu_bar_items_used
12866 instead of EMACS_INT, since it always fits in int.
12868 * menu.c (grow_menu_items): Check for int overflow.
12870 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12872 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12873 Before, the code was not consistent. These values cannot exceed
12874 2**31 - 1 so there's no need to make them unsigned.
12875 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12876 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12877 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12879 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12881 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12882 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12883 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12884 presumably because the widths might not match.
12886 * window.c (size_window): Avoid needless test at loop start.
12888 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12890 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12892 2011-05-12 Drew Adams <drew.adams@oracle.com>
12894 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12896 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12898 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12899 `width' to `bar_area_x' and `bar_area_width', respectively.
12900 (x_scroll_run): Take account of fringe background extension.
12902 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12903 Rename local vars `left' and `width' to `bar_area_x' and
12904 `bar_area_width', respectively.
12905 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12906 background extension.
12908 2011-05-10 Jim Meyering <meyering@redhat.com>
12910 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12912 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12914 * image.c (Finit_image_library): Return t for built-in image types,
12915 like pbm and xbm. (Bug#8640)
12917 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12919 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12921 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12923 * w32console.c (Fset_screen_color): Doc fix.
12924 (Fget_screen_color): New function.
12925 (syms_of_ntterm): Defsubr it.
12927 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12928 unlink the temporary file if Fcall_process didn't create it in the
12930 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12931 child process will be redirected to a file specified with `:file'.
12932 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12933 cue to call_process_cleanup not to close that handle.
12935 2011-05-07 Ben Key <bkey76@gmail.com>
12937 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12938 one of two shell specific rules, either bootstrap-temacs-CMD or
12939 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12940 to the previous implementation of the bootstrap-temacs rule.
12941 The bootstrap-temacs-CMD rule is similar to the previous
12942 implementation of the bootstrap-temacs rule except that it
12943 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12946 These changes, along with some changes to nt/configure.bat,
12947 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12948 earlier fix to add support for --cflags and --ldflags options
12949 that include quotes so that it works whether make uses cmd or
12952 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12954 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12955 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12957 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12958 a string. Handle both cases.
12959 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12960 (Fdbus_register_method): Use Qinvalid_function.
12962 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12964 * makefile.w32-in: Update dependencies.
12965 (LISP_H): Add inttypes.h and stdin.h.
12966 (PROCESS_H): Add unistd.h.
12968 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12970 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12971 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12973 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12975 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12977 * term.c (vfatal): Remove stray call to va_end.
12978 It's not needed and the C Standard doesn't allow it here anyway.
12980 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12981 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12983 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12986 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12988 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12990 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12992 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12994 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12996 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12997 * charset.c (Fdefine_charset_internal): Don't initialize
12998 charset.code_space[15]. The value was garbage, on hosts with
12999 32-bit int (Bug#8600).
13001 * lread.c (read_integer): Be more consistent with string-to-number.
13002 Use string_to_number to do the actual conversion; this avoids
13003 rounding errors and fixes some other screwups. Without this fix,
13004 for example, #x1fffffffffffffff was misread as -2305843009213693952.
13005 (digit_to_number): Move earlier, for benefit of read_integer.
13006 Return -1 if the digit is out of range for the base, -2 if it is
13007 not a digit in any supported base. (Bug#8602)
13009 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
13011 * dispnew.c (scrolling_window): Return 1 if we scrolled,
13012 to match comment at start of function. This also removes a
13013 GCC warning about overflow in a 32+64-bit port.
13015 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
13017 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
13018 Reported by Stefan Monnier in
13019 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
13020 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13021 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
13023 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
13024 (EMACS_UINTPTR): Likewise, with uintptr_t.
13026 * lisp.h: Prefer 64-bit EMACS_INT if available.
13027 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
13028 on 32-bit hosts that have 64-bit int, so that they can access
13030 However, temporarily disable this change unless the temporary
13031 symbol WIDE_EMACS_INT is defined.
13033 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
13035 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
13036 This removes an assumption that EMACS_INT and long are the same
13037 width as pointers. The assumption is true for Emacs porting targets
13038 now, but we want to make other targets possible.
13039 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
13040 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
13041 In the rest of the code, change types of integers that hold casted
13042 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
13043 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
13044 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
13045 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
13046 No need to cast type when ORing.
13047 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
13048 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
13049 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
13050 assume EMACS_INT is the same width as char *.
13051 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
13052 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
13053 Remove no-longer-needed casts.
13054 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
13055 (xg_tool_bar_help_callback, xg_make_tool_item):
13056 Use EMACS_INTPTR to hold an integer
13057 that will be cast to void *; this can avoid a GCC warning
13058 if EMACS_INT is not the same width as void *.
13059 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
13060 * xdisp.c (display_echo_area_1, resize_mini_window_1):
13061 (current_message_1, set_message_1):
13062 Use a local to convert to proper width without a cast.
13063 * xmenu.c (dialog_selection_callback): Likewise.
13065 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
13066 Also, don't assume VALBITS / RAND_BITS is less than 5,
13067 and don't rely on undefined behavior when shifting a 1 left into
13069 * lisp.h (get_random): Change signature to match.
13071 * lread.c (hash_string): Use size_t, not int, for hash computation.
13072 Normally we prefer signed values; but hashing is special, because
13073 it's better to use unsigned division on hash table sizes so that
13074 the remainder is nonnegative. Also, size_t is the natural width
13075 for hashing into memory. The previous code used 'int', which doesn't
13076 retain enough info to hash well into very large tables.
13077 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
13079 * dbusbind.c: Don't possibly lose pointer info when converting.
13080 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
13081 Use XPNTR rather than XHASH, so that the high-order bits of
13082 the pointer aren't lost when converting through void *.
13084 * eval.c (Fautoload): Don't double-shift a pointer.
13086 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

13120 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
13121 Remove unused parameter `fildes'.
13122 * process.c (read_process_output, send_process): Don't pass it.
13124 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
13126 Fix previous change: the library cache is defined in w32.c.
13127 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
13128 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

13170 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
13171 instead of gnutls_record_check_pending.
13173 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
13175 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
13177 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
13178 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
13181 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
13183 * xterm.c (x_set_frame_alpha): Do not set property on anything

13218 (Fcall_process_region): Ditto.
13220 2011-04-30 Eli Zaretskii <eliz@gnu.org>
13222 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
13223 rather than `XVECTOR (FOO)->size'.
13225 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
13226 inttypes.h, as a gnulib replacement is used if it not available in
13229 2011-04-21 Eli Zaretskii <eliz@gnu.org>
13231 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
13232 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
13233 of MOST_POSITIVE_FIXNUM. (Bug#8528)
13235 * coding.c (coding_alloc_by_realloc): Error out if destination
13236 will grow beyond MOST_POSITIVE_FIXNUM.
13237 (decode_coding_emacs_mule): Abort if there isn't enough place in
13238 charbuf for the composition carryover bytes. Reserve an extra
13239 space for up to 2 characters produced in a loop.

13293 Improve `doprnt' and its usage. (Bug#8545)
13294 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
13295 `format_end'. Remove support for %l as a conversion specifier.
13296 Don't use xrealloc. Improve diagnostics when the %l size modifier
13297 is used. Update the commentary.
13299 * eval.c (verror): Simplify calculation of size_t.
13301 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
13304 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
13306 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
13309 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
13311 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
13312 This makes this file independent of the recent pseudovector change.
13314 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
13316 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
13318 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
13319 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
13320 Remove unused local.
13321 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
13323 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
13324 GCC 4.6.0 optimizes based on type-based alias analysis.
13325 For example, if b is of type struct buffer * and v of type struct
13326 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
13327 != &v->size, and therefore "v->size = 1; b->size = 2; return
13328 v->size;" must therefore return 1. This assumption is incorrect
13329 for Emacs, since it type-puns struct Lisp_Vector * with many other
13330 types. To fix this problem, this patch adds a new type struct
13331 vectorlike_header that documents the constraints on layout of vectors
13332 and pseudovectors, and helps optimizing compilers not get fooled
13333 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
13334 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
13335 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
13337 (XSETPVECTYPE): Rewrite in terms of new macro.
13338 (XSETPVECTYPESIZE): New macro, specifying both type and size.
13339 This is a bit clearer, and further avoids the possibility of
13340 undesirable aliasing.
13341 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
13342 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
13343 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
13344 since Lisp_Subr is a special case (no "next" field).
13345 (ASIZE): Now uses header.size rather than size.
13346 All previous uses of XVECTOR (foo)->size replaced to use this macro,
13347 to avoid the hassle of writing XVECTOR (foo)->header.size.
13348 (struct vectorlike_header): New type.
13349 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
13350 object, to help avoid aliasing.
13351 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
13352 (SUBRP): Likewise, since Lisp_Subr is a special case.
13353 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
13354 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
13355 (struct Lisp_Hash_Table): Combine first two members into a single
13356 struct vectorlike_header member. All uses of "size" and "next" members
13357 changed to be "header.size" and "header.next".
13358 * buffer.h (struct buffer): Likewise.
13359 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
13360 * frame.h (struct frame): Likewise.
13361 * process.h (struct Lisp_Process): Likewise.
13362 * termhooks.h (struct terminal): Likewise.
13363 * window.c (struct save_window_data, struct saved_window): Likewise.
13364 * window.h (struct window): Likewise.
13365 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
13366 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
13367 * buffer.c (init_buffer_once): Likewise.
13368 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
13370 * process.c (Fformat_network_address): Use local var for size,
13373 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
13375 Make the Lisp reader and string-to-float more consistent (Bug#8525)
13376 * data.c (atof): Remove decl; no longer used or needed.
13377 (digit_to_number): Move to lread.c.
13378 (Fstring_to_number): Use new string_to_number function, to be
13379 consistent with how the Lisp reader treats infinities and NaNs.
13380 Do not assume that floating-point numbers represent EMACS_INT
13381 without losing information; this is not true on most 64-bit hosts.
13382 Avoid double-rounding errors, by insisting on integers when
13383 parsing non-base-10 numbers, as the documentation specifies.
13384 * lisp.h (string_to_number): New decl, replacing ...
13385 (isfloat_string): Remove.
13386 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
13387 (read1): Do not accept +. and -. as integers; this
13388 appears to have been a coding error. Similarly, do not accept
13389 strings like +-1e0 as floating point numbers. Do not report
13390 overflow for integer overflows unless the base is not 10 which
13391 means we have no simple and reliable way to continue.
13392 Break out the floating-point parsing into a new
13393 function string_to_number, so that Fstring_to_number parses
13394 floating point numbers consistently with the Lisp reader.
13395 (digit_to_number): Move here from data.c. Make it static inline.
13396 (E_CHAR, EXP_INT): Remove, replacing with ...
13397 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
13398 (string_to_number): New function, replacing isfloat_string.
13399 This function checks for valid syntax and produces the resulting
13400 Lisp float number too. Rework it so that string-to-number
13401 no longer mishandles examples like "1.0e+". Use strtoumax,
13402 so that overflow for non-base-10 numbers is reported only when
13403 there's no portable and simple way to convert to floating point.
13405 * textprop.c (set_text_properties_1): Rewrite for clarity,
13406 and to avoid GCC warning about integer overflow.
13408 * intervals.h (struct interval): Use EMACS_INT for members
13409 where EMACS_UINT might cause problems. See
13410 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
13411 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
13412 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
13414 (offset_intervals): Tell GCC not to worry about length overflow
13415 when negating a negative length.
13417 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
13418 (overrun_check_free): Likewise.
13420 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
13421 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
13424 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13425 (gnutls_make_error): Rename local to avoid shadowing.
13426 (gnutls_emacs_global_deinit): ifdef out; not used.
13427 (Fgnutls_boot): Use const for pointer to readonly storage.
13428 Comment out unused local. Fix pointer signedness problems.
13430 * lread.c (openp): Don't stuff size_t into an 'int'.
13431 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
13432 about possible signed overflow.
13434 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
13435 (GDK_KEY_g): Don't define if already defined.
13436 (xg_prepare_tooltip): Avoid pointer signedness problem.
13437 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
13439 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
13440 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
13442 * xfns.c (Fx_window_property): Simplify a bit,
13443 to make a bit faster and to avoid GCC 4.6.0 warning.
13444 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
13446 * fns.c (internal_equal): Don't assume size_t fits in int.
13448 * alloc.c (compact_small_strings): Tighten assertion a little.
13450 Replace pEd with more-general pI, and fix some printf arg casts.
13451 * lisp.h (pI): New macro, generalizing old pEd macro to other
13452 conversion specifiers. For example, use "...%"pI"d..." rather
13453 than "...%"pEd"...".
13454 (pEd): Remove. All uses replaced with similar uses of pI.
13455 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
13456 * alloc.c (check_pure_size): Don't overflow by converting size to int.
13457 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
13458 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
13459 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
13460 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
13461 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
13463 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
13464 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
13465 * print.c (safe_debug_print, print_object): Likewise.
13466 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
13468 Use pI instead of if-then-else-abort. Use %p to avoid casts,
13469 avoiding the 0 flag, which is not portable.
13470 * process.c (Fmake_network_process): Use pI to avoid cast.
13471 * region-cache.c (pp_cache): Likewise.
13472 * xdisp.c (decode_mode_spec): Likewise.
13473 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
13474 behavior on 64-bit hosts with printf arg.

13476 (x_stop_queuing_selection_requests): Likewise.
13477 (x_get_window_property): Don't truncate byte count to an 'int'
13480 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
13481 here, since it parses constructs like leading '-' and spaces,
13482 which are not wanted; and it overflows with large numbers.
13483 Instead, simply match F[0-9]+, which is what is wanted anyway.
13485 * alloc.c: Remove unportable assumptions about struct layout.
13486 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
13487 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
13488 (allocate_vectorlike, make_pure_vector): Use the new macros,
13489 plus offsetof, to remove unportable assumptions about struct layout.
13490 These assumptions hold on all porting targets that I know of, but
13491 they are not guaranteed, they're easy to remove, and removing them
13492 makes further changes easier.
13494 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
13495 This doesn't fix a bug but makes the code clearer.
13496 (string_overrun_cookie): Now const. Use initializers that
13497 don't formally overflow signed char, to avoid warnings.
13498 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
13499 can cause Emacs to crash when string overrun checking is enabled.
13500 (allocate_buffer): Don't assume sizeof (struct buffer) is a
13501 multiple of sizeof (EMACS_INT); it need not be, if
13502 alignof(EMACS_INT) < sizeof (EMACS_INT).
13503 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
13505 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

13532 2011-04-25 Eli Zaretskii <eliz@gnu.org>
13534 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
13535 "cast to pointer from integer of different size".
13537 Improve doprnt and its use in verror. (Bug#8545)
13538 * doprnt.c (doprnt): Document the set of format control sequences
13539 supported by the function. Use SAFE_ALLOCA instead of always
13542 * eval.c (verror): Don't limit the buffer size at size_max-1, that
13543 is one byte too soon. Don't use xrealloc; instead xfree and
13546 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
13548 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

13552 gnutls_global_initialized. Added internals for the
13553 :verify-hostname-error, :verify-error, and :verify-flags
13554 parameters of `gnutls-boot' and documented those parameters in the
13555 docstring. Start callback support.
13556 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
13557 unless a fatal error occurred. Call gnutls_alert_send_appropriate

13618 changes in globals.h immediately force recompilation.
13619 (TAGS): Depend on $(CURDIR)/m/intel386.h and
13620 $(CURDIR)/s/ms-w32.h.

13635 conversions. Support %l conversion. Don't assume an EMACS_INT
13636 argument for integer conversions and for %c.
13638 * lisp.h (doprnt): Restore prototype.
13640 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

13655 * callint.c (Fcall_interactively): When displaying error message
13656 about invalid control letter, pass the character's codepoint, not

13661 codepoint of an invalid character, to avoid displaying a bogus
13664 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
13665 `error', not SYMBOL_NAME itself.
13667 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
13668 character arguments to `error'.
13670 * charset.c (check_iso_charset_parameter): Fix incorrect argument
13671 to `error' in error message about FINAL_CHAR argument. Make sure
13672 FINAL_CHAR is a character, and use %c when it is passed as
13673 argument to `error'.
13675 2011-04-23 Eli Zaretskii <eliz@gnu.org>
13677 * s/ms-w32.h (localtime): Redirect to sys_localtime.
13679 * w32.c: Include <time.h>.

13741 * xfaces.c (USG, __TIMEVAL__): Likewise.
13743 * dispextern.h (struct redisplay_interface): Rename param
13744 to avoid shadowing.
13745 * termhooks.h (struct terminal): Likewise.
13746 * xterm.c (xembed_send_message): Likewise.

13793 out-of-range initializers by using, for example, '\xab' rather
13796 * xgselect.c (xgselect_initialize): Check vs interface
13797 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

13862 * nsfont.m: Fixed bugs in ns_get_family and
13863 ns_descriptor_to_entity that were caused by using free to
13864 deallocate memory blocks that were allocated by xmalloc (via
13865 xstrdup). This caused Emacs to crash when compiled with
13866 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
13867 --enable-checking=xmallocoverrun). xfree is now used to
13868 deallocate these memory blocks.

13882 (emacs_read, emacs_write): Remove check for negative size, as the
13883 Emacs source code has been audited now.
13884 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
13885 (emacs_read, emacs_write): Use it.
13886 * process.c (send_process): Adjust to the new signatures of
13887 emacs_write and emacs_gnutls_write. Do not attempt to store
13888 a byte offset into an 'int'; it might overflow.

14349 * xsettings.c (read_and_apply_settings): Likewise.
14351 * alloc.c (overrun_check_malloc, overrun_check_realloc)
14352 (overrun_check_free): Protoize.
14354 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
14356 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
14357 since callers should never pass a negative size.
14358 Change the signature to match that of plain 'read' and 'write'; see
14359 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
14360 * lisp.h: Update prototypes of emacs_write and emacs_read.
14362 2011-04-11 Eli Zaretskii <eliz@gnu.org>
14364 * xdisp.c (redisplay_window): Don't try to determine the character
14365 position of the scroll margin if the window start point w->startp
14366 is outside the buffer's accessible region. (Bug#8468)
14368 2011-04-10 Eli Zaretskii <eliz@gnu.org>
14370 Fix write-region and its subroutines for buffers > 2GB.
14371 * fileio.c (a_write, e_write): Modify declaration of arguments and
14372 local variables to support buffers larger than 2GB.
14373 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
14375 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
14376 argument, local variables, and return value.
14378 * lisp.h: Update prototypes of emacs_write and emacs_read.
14380 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
14382 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
14384 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
14386 Fix more problems found by GCC 4.6.0's static checks.
14388 * xdisp.c (vmessage): Use a better test for character truncation.
14390 * charset.c (load_charset_map): <, not <=, for optimization,
14391 and to avoid potential problems with integer overflow.
14392 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
14393 * casetab.c (set_identity, shuffle): Likewise.
14394 * editfns.c (Fformat): Likewise.
14395 * syntax.c (skip_chars): Likewise.
14397 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
14398 This also lets GCC 4.6.0 generate slightly better loop code.
14400 * callint.c (Fcall_interactively): <, not <=, for optimization.
14401 (Fcall_interactively): Count the number of arguments produced,
14402 not the number of arguments given. This is simpler and lets GCC
14403 4.6.0 generate slightly better code.
14405 * ftfont.c: Distingish more carefully between FcChar8 and char.
14406 The previous code passed unsigned char * to a functions like
14407 strlen and xstrcasecmp that expect char *, which does not
14408 conform to the C standard.
14409 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
14410 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
14411 char * when the C standard requires it.
14413 * keyboard.c (read_char): Remove unused var.
14415 * eval.c: Port to Windows vsnprintf (Bug#8435).
14416 Include <limits.h>.
14417 (SIZE_MAX): Define if the headers do not.
14418 (verror): Do not give up if vsnprintf returns a negative count.
14419 Instead, grow the buffer. This ports to Windows vsnprintf, which
14420 does not conform to C99. Problem reported by Eli Zaretskii.
14421 Also, simplify the allocation scheme, by avoiding the need for
14422 calling realloc, and removing the ALLOCATED variable.
14424 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
14426 Remove invocations of doprnt, as Emacs now uses vsnprintf.
14427 But keep the doprint source code for now, as we might revamp it
14428 and use it again (Bug#8435).
14429 * lisp.h (doprnt): Remove.
14430 * Makefile.in (base_obj): Remove doprnt.o.
14431 * deps.mk (doprnt.o): Remove.
14433 error: Print 32- and 64-bit integers portably (Bug#8435).
14434 Without this change, on typical 64-bit hosts error ("...%d...", N)
14435 was used to print both 32- and 64-bit integers N, which relied on
14436 undefined behavior.
14437 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
14438 * lisp.h (error, verror): Mark as printf-like functions.
14439 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
14440 Report overflow in size calculations when allocating printf buffer.
14441 Do not truncate output string at its first null byte.
14442 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
14443 Truncate the output at a character boundary, since vsnprintf does not
14445 * charset.c (check_iso_charset_parameter): Convert internal
14446 character to string before calling 'error', since %c now has the
14448 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
14449 overflow when computing char to be passed to 'error'. Do not
14450 pass Lisp_Object to 'error'; pass the integer instead.
14451 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
14452 formatted with plain %d.
14454 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
14456 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
14458 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
14460 * xterm.c (x_catch_errors): Remove duplicate declaration.
14462 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
14464 * xdisp.c, lisp.h (message_nolog): Remove; unused.
14466 2011-04-10 Jim Meyering <meyering@redhat.com>
14468 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
14469 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
14470 return ssize_t not "int", and use size_t as the buffer length.
14471 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
14472 * gnutls.h: Update declarations.
14473 * process.c (read_process_output): Use ssize_t, to match.
14474 (send_process): Likewise.
14476 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14478 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
14480 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
14482 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
14483 Use unsigned char, to match FcChar8 type definition.
14485 * xterm.c (handle_one_xevent):
14486 * xmenu.c (create_and_show_popup_menu):
14487 * xselect.c (x_decline_selection_request)
14488 (x_reply_selection_request): Avoid type-punned deref of X events.
14490 2011-04-09 Eli Zaretskii <eliz@gnu.org>
14492 Fix some uses of `int' instead of EMACS_INT.
14493 * search.c (string_match_1, fast_string_match)
14494 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
14495 (scan_buffer, find_next_newline_no_quit)
14496 (find_before_next_newline, search_command, Freplace_match)
14497 (Fmatch_data): Make some `int' variables be EMACS_INT.
14499 * xdisp.c (display_count_lines): 3rd argument and return value now
14500 EMACS_INT. All callers changed.
14501 (pint2hrstr): Last argument is now EMACS_INT.
14503 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
14504 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
14505 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
14506 (decode_coding_utf_16, decode_coding_emacs_mule)
14507 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
14508 (decode_coding_ccl, decode_coding_charset)
14509 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
14510 (decode_coding_iso_2022, decode_coding_emacs_mule)
14511 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
14512 <char_offset, last_offset>: Declare EMACS_INT.
14513 (encode_coding_utf_8, encode_coding_utf_16)
14514 (encode_coding_emacs_mule, encode_invocation_designation)
14515 (encode_designation_at_bol, encode_coding_iso_2022)
14516 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
14517 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
14519 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
14520 (encode_invocation_designation): Last argument P_NCHARS is now
14522 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
14523 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
14525 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
14528 * ccl.c (Fccl_execute_on_string): Declare some variables
14531 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
14533 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
14535 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
14537 * process.c (Fformat_network_address): Doc fix.
14539 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
14541 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
14543 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
14545 * keyboard.c (read_char): Call Lisp function help-form-show,
14546 instead of using internal_with_output_to_temp_buffer.
14547 (Qhelp_form_show): New var.
14548 (syms_of_keyboard): Use DEFSYM macro.
14550 * print.c (internal_with_output_to_temp_buffer): Function deleted.
14552 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
14554 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
14556 * process.c (Flist_processes): Remove to Lisp.
14557 (list_processes_1): Delete.

14561 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
14563 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
14565 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
14567 Fix more problems found by GCC 4.6.0's static checks.
14569 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
14571 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
14573 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14575 * xdisp.c (vmessage): Mark as a printf-like function.
14577 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
14579 * sound.c (sound_warning): Don't crash if arg contains a printf format.
14581 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
14582 printf-like functions.
14583 (tiff_load): Add casts to remove these marks before passing them
14584 to system-supplied API.
14586 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14588 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14589 This avoids several warnings with gcc -Wstrict-overflow.
14590 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14591 directly, rather than having caller test rule sign. This avoids
14592 some unnecessary tests.
14593 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14594 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14595 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14597 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14598 (xfont_open): Avoid unnecessary tests.
14600 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14602 * composite.h, composite.c (composition_gstring_put_cache):
14603 Use EMACS_INT, not int, for length.

14609 by using the new macro.
14611 * textprop.c (set_text_properties_1): Change while to do-while,
14612 since the condition is always true at first.
14614 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14615 (interval_deletion_adjustment): Return unsigned value.
14618 * process.c (list_processes_1, create_pty, read_process_output):

14630 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14631 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14632 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14634 * print.c (print_error_message): Avoid int overflow.
14636 * font.c (font_list_entities): Redo for clarity,
14637 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14639 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14640 (font_score): Avoid potential overflow in diff calculation.
14642 * fns.c (substring_both): Remove var that is set but not used.
14643 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14645 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14647 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14648 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14649 can always succeed if overflow has undefined behavior.
14651 * search.c (boyer_moore, wordify): Remove vars set but not used.
14652 (wordify): Omit three unnecessary tests.
14654 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14655 All callers changed. This avoids the need for an unused var.
14657 * casefiddle.c (casify_region): Remove var that is set but not used.
14659 * dired.c (file_name_completion): Remove var that is set but not used.
14661 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14663 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14664 (Finsert_file_contents): Remove unnecessary code checking fd.
14666 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14667 Check for integer overflow on size calculations.
14669 * buffer.c (Fprevious_overlay_change): Remove var that is set
14672 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14673 Remove vars that are set but not used.
14674 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14675 (timer_check_2): Mark vars as initialized.
14677 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14679 * image.c (lookup_image): Remove var that is set but not used.
14680 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14682 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14683 that are set but not used.
14685 * xfns.c (make_invisible_cursor): Don't return garbage
14686 if XCreateBitmapFromData fails (Bug#8410).
14688 * xselect.c (x_get_local_selection, x_handle_property_notify):
14689 Remove vars that are set but not used.
14691 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

14701 (map_tty_color) [!defined MSDOS]: Likewise.
14703 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14705 * coding.c: Remove vars that are set but not used.
14706 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14707 All callers changed.
14708 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
14709 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
14710 (decode_coding_charset): Remove vars that are set but not used.
14712 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
14713 that is set but not used.
14715 * print.c (print_object): Remove var that is set but not used.
14717 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14718 The gnulib version avoids calling malloc in the usual case,
14719 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14720 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14721 * filelock.c (current_lock_owner): Likewise.
14722 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

14725 (emacs_readlink): New function.
14726 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14727 ../lib/careadlinkat.h.
14729 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14731 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14732 first non-nil return value).

14736 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
14737 if not defined (Bug#8403).

14746 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
14747 and thereabouts. All callers changed.
14748 (get_per_char_metric): Remove parameter `f', unused since
14749 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

14753 do not dereference NULL upon failed strdup
14754 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14755 (ns_get_family): Likewise.
14757 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

14797 (Feval): New `lexical' arg.
14798 (eval_sub): New function extracted from Feval. Use it almost

14806 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14807 but without exporting it to Lisp.
14809 * doc.c (Fdocumentation, store_function_docstring):
14810 * data.c (Finteractive_form): Handle closures.
14812 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14815 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14817 (exec_byte_code): New function extracted from Fbyte_code to handle new
14818 calling convention for byte-code-functions. Add new byte-codes.
14820 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14822 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14824 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14826 * xdisp.c (redisplay_internal): Fix prototype.
14828 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14830 * xdisp.c (SCROLL_LIMIT): New macro.
14831 (try_scrolling): Use it when setting scroll_limit.
14832 Limit scrolling to 100 screen lines.
14833 (redisplay_window): Even when falling back on "recentering",
14834 position point in the window according to scroll-conservatively,
14835 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14837 (try_scrolling): When point is above the window, allow searching
14838 as far as scroll_max, or one screenful, to compute vertical
14839 distance from PT to the scroll margin position. This prevents
14840 try_scrolling from unnecessarily failing when
14841 scroll-conservatively is set to a value slightly larger than the
14842 window height. Clean up the case of PT below the margin at bottom
14843 of window: scroll_max can no longer be INT_MAX. When aggressive
14844 scrolling is in use, don't let point enter the opposite scroll
14845 margin as result of the scroll.
14846 (syms_of_xdisp) <scroll-conservatively>: Document the
14847 threshold of 100 lines for never-recentering scrolling.
14849 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14851 * dispextern.h (move_it_by_lines):
14852 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
14853 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
14854 (message_log_check_duplicate): Remove parameters `prev_bol' and
14855 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14856 (redisplay_internal): Remove parameter `preserve_echo_area',
14857 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14859 * indent.c (Fvertical_motion):
14860 * window.c (window_scroll_pixel_based, Frecenter):
14861 Don't pass `need_y_p' to `move_it_by_lines'.
14863 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14865 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14866 steal a few bits to be more compact.
14867 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
14868 Remove unneeded casts.
14870 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14872 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14874 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14875 binding" message (bug#7967).
14877 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14879 Fix more problems found by GCC 4.6.0's static checks.
14881 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14882 Remove unused local var.
14884 * editfns.c (Fmessage_box): Remove unused local var.
14886 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14887 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14888 Omit unused local vars.
14889 * window.c (shrink_windows): Omit unused local var.
14890 * menu.c (digest_single_submenu): Omit unused local var.
14891 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14892 Omit unused local var.
14894 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14895 Don't assume string length fits in int.
14896 (keyremap_step, read_key_sequence): Use size_t for sizes.
14897 (read_key_sequence): Don't check last_real_key_start redundantly.
14899 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
14900 instead of alloca (Bug#8344).
14902 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14903 (Fbacktrace_frame): Don't assume nframes fits in int.
14905 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
14907 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
14910 * term.c (produce_glyphless_glyph): Remove unnecessary test.
14912 * cm.c (calccost): Turn while-do into do-while, for clarity.
14914 * keyboard.c (syms_of_keyboard): Use the same style as later
14915 in this function when indexing through an array. This also
14916 works around GCC bug 48267.
14918 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14920 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14922 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14923 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14925 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14926 This avoids undefined behavior on integer overflow, and is a bit
14927 more convenient anyway since it is compared to a size_t variable.
14929 Variadic C functions now count arguments with size_t, not int.
14930 This avoids an unnecessary limitation on 64-bit machines, which
14931 caused (substring ...) to crash on large vectors (Bug#8344).
14932 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
14933 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
14934 All variadic functions and their callers changed accordingly.
14935 (struct gcpro.nvars): Now size_t, not int. All uses changed.
14936 * data.c (arith_driver, float_arith_driver): Likewise.
14937 * editfns.c (general_insert_function): Likewise.
14938 * eval.c (struct backtrace.nargs, interactive_p)
14939 (internal_condition_case_n, run_hook_with_args, apply_lambda)
14940 (funcall_lambda, mark_backtrace): Likewise.
14941 * fns.c (concat): Likewise.
14942 * frame.c (x_set_frame_parameters): Likewise.
14943 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14944 0 if not found, not -1. All callers changed.
14946 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14947 (stack_copy_size): Now size_t, not int.
14948 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14950 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14952 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14953 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14954 All callers changed.
14956 * lisp.h (multibyte_char_to_unibyte):
14957 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
14958 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
14959 * character.h (CHAR_TO_BYTE8):
14960 * cmds.c (internal_self_insert):
14961 * editfns.c (general_insert_function):
14962 * keymap.c (push_key_description):
14963 * search.c (Freplace_match):
14964 * xdisp.c (message_dolog, set_message_1): All callers changed.
14966 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14968 * keyboard.c (safe_run_hook_funcall): New function.
14969 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14970 don't set the hook to nil, but remove the offending function instead.
14971 (Qcommand_hook_internal): Remove, unused.
14972 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14973 Vcommand_hook_internal.
14975 * eval.c (enum run_hooks_condition): Remove.
14976 (funcall_nil, funcall_not): New functions.
14977 (run_hook_with_args): Call each function through a `funcall' argument.
14978 Remove `cond' argument, now redundant.
14979 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
14980 (Frun_hook_with_args_until_failure): Adjust accordingly.
14981 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
14983 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14985 * dispextern.h (string_buffer_position): Remove declaration.
14987 * print.c (strout): Remove parameter `multibyte', unused since
14988 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
14990 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
14991 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
14992 All callers changed.
14994 * w32.c (_wsa_errlist): Use braces for struct initializers.
14996 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
14997 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
14998 All callers changed.
14999 (string_buffer_position): Likewise. Also, make static (it's never
15000 used outside xdisp.c).
15001 (cursor_row_p): Remove parameter `w', unused since
15002 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

15004 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
15005 All callers changed.
15007 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
15009 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
15011 2011-03-27 Anders Lindgren <andlind@gmail.com>
15013 * nsterm.m (ns_menu_bar_is_hidden): New variable.
15014 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
15015 (ns_update_auto_hide_menu_bar): New functions.
15016 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
15017 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and

15020 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
15022 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
15024 * nsmenu.m (runDialogAt): Remove argument to timer_check.
15026 2011-03-27 Glenn Morris <rgm@gnu.org>
15028 * syssignal.h: Replace RETSIGTYPE with void.
15029 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
15030 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
15031 Replace SIGTYPE with void everywhere.
15032 * s/usg5-4-common.h (SIGTYPE): Remove definition.
15033 * s/template.h (SIGTYPE): Remove commented out definition.
15035 2011-03-26 Eli Zaretskii <eliz@gnu.org>
15037 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
15038 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
15040 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
15042 * w32.c (read_unc_volume): Use parameter `henum', instead of
15043 global variable `wget_enum_handle'.
15045 * keymap.c (describe_vector): Remove parameters `indices' and
15046 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

15049 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
15051 * keyboard.c (timer_check): Remove parameter `do_it_now',
15052 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
15053 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
15054 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
15056 * keyboard.c (read_char):
15057 * w32menu.c (w32_menu_display_help):
15058 * xmenu.c (show_help_event, menu_help_callback):
15059 Adjust calls to `show_help_echo'.
15061 * gtkutil.c (xg_maybe_add_timer):
15062 * keyboard.c (readable_events):
15063 * process.c (wait_reading_process_output):
15064 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
15066 * insdel.c (adjust_markers_gap_motion):
15067 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
15068 (gap_left, gap_right): Don't call it.
15070 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
15072 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
15073 incurred during fontification.

15114 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
15116 * w32term.c (x_set_glyph_string_clipping):
15117 Don't pass uninitialized region to CombineRgn.
15119 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
15121 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
15122 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
15123 (Fx_close_connection): Remove unused variable `i'.
15125 * w32font.c (w32font_draw): Return number of glyphs.

15139 (uniscribe_font_driver): Add missing initializers.
15141 2011-03-23 Julien Danjou <julien@danjou.info>
15143 * term.c (Fsuspend_tty, Fresume_tty):
15144 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
15145 * window.c (temp_output_buffer_show):
15146 * insdel.c (signal_before_change):
15147 * frame.c (Fhandle_switch_frame):
15148 * fileio.c (Fdo_auto_save):
15149 * emacs.c (Fkill_emacs):
15150 * editfns.c (save_excursion_restore):
15151 * cmds.c (internal_self_insert):
15152 * callint.c (Fcall_interactively):
15153 * buffer.c (Fkill_all_local_variables):
15154 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
15156 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
15157 unconditionally since it does the check itself.
15159 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
15161 Fix more problems found by GCC 4.5.2's static checks.
15163 * coding.c (encode_coding_raw_text): Avoid unnecessary test
15164 the first time through the loop, since we know p0 < p1 then.
15165 This also avoids a gcc -Wstrict-overflow warning.
15167 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
15168 leading to a memory leak, possible in functions like
15169 load_charset_map_from_file that can allocate an unbounded number
15170 of objects (Bug#8318).
15172 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
15173 that could (at least in theory) be that large.
15175 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
15176 This is less likely to overflow, and avoids undefined behavior if
15177 overflow does occur. All callers changed. Use strtoul to scan
15178 for the unsigned long integer.
15179 (pint2hrstr): Simplify and tune code slightly.
15180 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
15182 * scroll.c (do_scrolling): Work around GCC bug 48228.
15183 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
15185 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
15186 This also avoids a warning with gcc -Wstrict-overflow.
15187 (validate_x_resource_name): Simplify count usage.
15188 This also avoids a warning with gcc -Wstrict-overflow.
15190 * fileio.c (Fcopy_file): Report error if fchown or fchmod
15193 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
15195 * process.c (Fmake_network_process): Use socklen_t, not int,
15196 where POSIX says socklen_t is required in portable programs.
15197 This fixes a porting bug on hosts like 64-bit HP-UX, where
15198 socklen_t is wider than int (Bug#8277).
15199 (Fmake_network_process, server_accept_connection):
15200 (wait_reading_process_output, read_process_output):
15203 * process.c: Rename or move locals to avoid shadowing.
15204 (list_processes_1, Fmake_network_process):
15205 (read_process_output_error_handler, exec_sentinel_error_handler):
15206 Rename or move locals.
15207 (Fmake_network_process): Define label "retry_connect" only if needed.
15208 (Fnetwork_interface_info): Fix pointer signedness.
15209 (process_send_signal): Add cast to avoid pointer signedness problem.
15210 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
15211 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
15213 Make tparam.h and terminfo.c consistent.
15214 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
15215 Include tparam.h instead, since it declares them.
15216 * cm.h (PC): Remove extern decl; tparam.h now does this.
15217 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
15218 * terminfo.c: Include tparam.h, to check interfaces.
15219 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
15220 (tparam): Adjust signature to match interface in tparam.h;
15221 this removes some undefined behavior. Check that outstring and len
15222 are zero, which they always are with Emacs.
15223 * tparam.h (PC, BC, UP): New extern decls.
15225 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
15226 (xftfont_open): Rename locals to avoid shadowing.
15228 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
15229 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
15230 (OTF_TAG_SYM): Omit macro if not needed.
15231 (ftfont_list): Remove unused local.
15232 (get_adstyle_property, ftfont_pattern_entity):
15233 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
15234 Rename locals to avoid shadowing.
15236 * xfont.c (xfont_list_family): Mark var as initialized.
15238 * xml.c (make_dom): Now static.

15277 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
15279 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
15280 This should get cleaned up, so that child_setup has the
15281 same signature on all platforms.
15283 * callproc.c (call_process_cleanup): Now static.
15284 (relocate_fd): Rename locals to avoid shadowing.
15286 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

15453 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15454 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
15455 to use the following functions instead of these macros.
15456 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
15457 EMACS_INT, since callers assume the returned value fits in int.
15458 (upcase1): Likewise, for UPCASE_TABLE.
15459 (uppercasep, lowercasep, upcase): New static inline functions.
15460 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

15470 (regex_compile, re_match_2_internal): Mark locals as initialized.
15471 (RETALLOC_IF): Define only if needed.
15472 (WORDCHAR_P): Likewise. This one is never needed, but is used
15473 only in a comment talking about a compiler bug, so put inside
15474 the #if 0 of that comment.
15475 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
15476 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

15503 New macros, so that the caller can use some names other than
15504 gcpro1, gcpro2, etc.
15505 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
15507 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
15508 argument, for consistency with GCPRO2_VAR, etc: it is now the
15509 prefix of the variable, not the variable itself. All uses
15511 * dired.c (directory_files_internal, file_name_completion):
15512 Rename locals to avoid shadowing.
15514 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
15515 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
15516 dired.c's scmp function, had undefined behavior.
15517 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
15518 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
15519 * buffer.h: ... to here, because these macros use current_buffer,
15520 and the new implementation with inline functions needs to have
15521 current_buffer in scope now, rather than later when the macros
15523 (downcase, upcase1): New static inline functions.
15524 (DOWNCASE, UPCASE1): Reimplement using these functions.
15525 This avoids undefined behavior in expressions like
15526 DOWNCASE (x) == DOWNCASE (y), which previously suffered
15527 from race conditions in accessing the global variables
15528 case_temp1 and case_temp2.
15529 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
15530 * lisp.h (case_temp1, case_temp2): Remove their decls.
15531 * character.h (ASCII_CHAR_P): Move from here ...
15532 * lisp.h: ... to here, so that the inline functions mentioned
15533 above can use them.
15535 * dired.c (directory_files_internal_unwind): Now static.
15537 * fileio.c (file_name_as_directory, directory_file_name):

15540 (file_name_as_directory): Use const pointers when appropriate.
15541 (Fexpand_file_name): Likewise. In particular, newdir might
15542 point at constant storage, so make it a const pointer.

15544 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
15546 (Fset_file_times, Finsert_file_contents, auto_save_error):

15551 to avoid shadowing.
15553 * marker.c (bytepos_to_charpos): Remove; unused.
15555 * lisp.h (verify_bytepos, count_markers): New decls,
15556 so that gcc does not warn that these functions aren't declared.
15558 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
15559 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
15560 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
15561 (copy_text): Remove unused local var.

15566 * buffer.c (fix_overlays_before): Mark locals as initialized.
15567 (fix_start_end_in_overlays): Likewise. This function should be
15568 simplified by using pointers-to-pointers, but that's a different
15570 (switch_to_buffer_1): Now static.
15571 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
15572 (report_overlay_modification): Rename locals to avoid shadowing.

15575 Fix pointer signedness issue.
15576 (sys_subshell): Mark local as volatile if checking for lint,
15577 to suppress a gcc -Wclobbered warning that does not seem to be right.
15578 (MAXPATHLEN): Define only if needed.
15580 * process.c (serial_open, serial_configure): Move decls from here ...
15581 * systty.h: ... to here, so that they can be checked.
15583 * fns.c (get_random, seed_random): Move extern decls from here ...
15584 * lisp.h: ... to here, so that they can be checked.
15586 * sysdep.c (reset_io): Now static.

15593 (DENSE_TABLE_SIZE): Remove; unused.
15594 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
15595 (describe_map_tree):
15596 Rename locals to avoid shadowing.
15598 * keyboard.c: Declare functions static if they are not used elsewhere.
