[bpt/emacs.git] / src / ChangeLog
1 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
2
3 Fix export of symbols to GDB (Bug#12036).
4 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
6 emacs.c, as this is a more-suitable home. Had this been done earlier
7 the fix for 12036 would have avoided some of the problems noted in
8 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9 would have been more obvious.
10 * emacs.c: Do not include <verify.h>; no longer needed.
11 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
12 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
13 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
14 Remove; now done in lisp.h.
15 * lisp.h (PUBLISH_TO_GDB): New macro.
16 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
17 (DATA_SEG_BITS): Use it.
18 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
19 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
20 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
21 not be usable in #if. This simplifies things.
22
23 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
24
25 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
26
27 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
28
29 Simplify export of symbols to GDB (Bug#12036).
30 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
31 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
32 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
33 Adjust to changes in lisp.h and emacs.c, by using
34 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
35 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
36 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
37 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
38 instead of gdb_valbits.
39 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
40 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
41 instead of gdb_array_mark_flag.
42 (xboolvector): Get size from $->size, not $->header.size.
43 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
44 (xreload, hook-run, hookpost-run): Remove.
45 * emacs.c: Include <verify.h>.
46 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
47 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
48 Remove.
49 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
50 (gdb_USE_LSB_TAG): New enum constants.
51 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
52 Also define these as enum constants, so they're visible to GDB.
53 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
54 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
55 as constants, so they're visible to GDB.
56 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
57 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
58 Now enum constants, not macros, so they're visible to GDB.
59 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
60 more convenient now. All uses changed.
61 (VALMASK) [USE_LSB_TAG]: Also define in this case.
62 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
63
64 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
65
66 Explicitly free restriction data that are not needed anymore.
67 * editfns.c (save_restriction_restore): Free restriction data.
68
69 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
70
71 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
72 add argument, tune behavior, and adjust all callers.
73
74 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
75
76 Use typedef for EMACS_INT, EMACS_UINT.
77 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
78 than macros. This simplifies debugging in the usual case, since
79 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
80 and it allows expressions involving EMACS_INT casts.
81 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
82
83 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
84
85 * nsterm.m (ns_read_socket): Return early if there is a modal
86 window (Bug#12043).
87
88 2012-07-25 Martin Rudalics <rudalics@gmx.at>
89
90 * frame.c (Fredirect_frame_focus): In doc-string don't mention
91 that FOCUS-FRAME can be omitted.
92
93 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
94
95 Adjust buffer text indirection counters at the end of Fkill_buffer.
96 * buffer.c (Fkill_buffer): Adjust indirection counters when the
97 buffer is definitely dead. This should really fix an issue reported
98 by Christoph Scholtes again. (Bug#12007).
99 (init_buffer_once): Initialize indirection counters of
100 buffer_defaults and buffer_local_symbols (for sanity and safety).
101
102 2012-07-24 Eli Zaretskii <eliz@gnu.org>
103
104 * xdisp.c (init_iterator): Don't compute dimensions of truncation
105 and continuation glyphs on tooltip frames, leave them at zero.
106 Avoids continued lines in tooltips. (Bug#11832)
107
108 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
109
110 Simplify copy_overlay.
111 * buffer.c (copy_overlay): Simplify. Use build_marker.
112 * lisp.h (struct Lisp_Overlay): Restore comment with minor tweaks.
113
114 2012-07-23 Eli Zaretskii <eliz@gnu.org>
115
116 * print.c (print_object): Don't crash when a frame's name is nil
117 or invalid. (Bug#12025)
118
119 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
120 it signals an error when a tooltip frame is being created.
121
122 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
123
124 Cleanup miscellaneous objects allocation and initialization.

128 * buffer.c (copy_overlays, Fmake_overlay): Use it.
129 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
130 (allocate_misc): Remove prototype.
131 (build_overlay): Add prototype.
132
133 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
134
135 Swap buffer text indirection counters in Fbuffer_swap_text.
136 * buffer.c (Fbuffer_swap_text): Swap indirections too.
137 This avoids crash reported by Christoph Scholtes at
138 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
139
140 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>

171
172 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

175 for the reasons.
176
177 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

306 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
307
308 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
309
310 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug

313
314 Remove some struct layout assumptions in bool vectors.
315 * alloc.c (bool_header_size): New constant.
316 (header_size, word_size): Move earlier, as they're now used earlier.
317 Use 'word_size' in a few more places, where it's appropriate.
318 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
319 padding before the data member of a bool vector.
320 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather

322
323 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
324
325 * eval.c (Fdefvar): Don't check constants since we only set the var if

864 * s/hpux10-20.h (HAVE_PERROR): Remove.
865 * sysdep.c (perror) [HPUX && !HAVE_PERROR]:
866 Remove dummy definition, as this problem was obsolete long ago.
867

893 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
894
895 Remove "#define unix" that is no longer needed (Bug#11905).
896 * s/aix4-2.h (unix): Remove; no longer needed.
897
898 EMACS_TIME simplification (Bug#11875).
899 This replaces macros (which typically do not work in GDB)
900 with functions, typedefs and enums, making the code easier to debug.
901 The functional style also makes code easier to read and maintain.
902 * systime.h: Include <sys/time.h> on all hosts, not just if
903 WINDOWSNT, since 'struct timeval' is needed in general.
904 (EMACS_TIME): Now a typedef, not a macro.
905 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
906 not macros.
907 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
908 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
909 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
910 (EMACS_TIME_LE): Now functions, not macros.
911 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
912 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
913 which are not functions. All uses rewritten to use:
914 (make_emacs_time): New function.
915 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
916 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
917 not functions. All uses rewritten to use the following, respectively:
918 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
919 (add_emacs_time, sub_emacs_time): New functions.
920 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
921 * fileio.c (Fcopy_file):
922 * xterm.c (XTflash): Get the current time closer to when it's used.
923 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

930 * frame.c (Fmake_terminal_frame):
931 * gtkutil.c (get_utf8_string):
932 * lread.c (openp):
933 * nsmenu.m (ns_update_menubar):
934 * regex.c (regerror):
935 Prefer memcpy to strncpy and strncat when either will do.
936 * fileio.c (Fsubstitute_in_file_name):
937 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
938 (menu_separator_name_p):
939 * nsmenu.m (ns_update_menubar):
940 Prefer memcmp to strncmp when either will do.
941 * nsterm.m: Include <ftoastr.h>.
942 (ns_get_color):
943 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
944 Prefer snprintf to strncpy.
945 * nsterm.m (ns_term_init):
946 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
947 * nsterm.m (ns_term_init):
948 Avoid the need for strncpy, by using build_string or
949 make_unibyte_string directly. Use dtoastr, not snprintf.
950 * process.c (Fmake_network_process): Diagnose service names that
951 are too long, rather than silently truncating them or creating
952 non-null-terminated names.
953 (Fnetwork_interface_info): Likewise, for interface names.
954 * sysdep.c (system_process_attributes) [GNU_LINUX]:
955 Prefer sprintf to strncat.
956 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
957 Prefer vsnprintf to vsprintf + strncpy.
958
959 2012-07-10 Glenn Morris <rgm@gnu.org>
960
961 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
962 Clarify fallback case.
963
964 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
965

967 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
968 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
969 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
970 where argument type is known to be a Lisp_Cons.
971
972 2012-07-10 Tom Tromey <tromey@redhat.com>
973
974 * bytecode.c (BYTE_CODE_THREADED): New macro.
975 (BYTE_CODES): New macro. Replaces all old byte-code defines.
976 (enum byte_code_op): New type.
977 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
978 (exec_byte_code): Use them. Use token threading when applicable.
979
980 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
981
982 Optimize pure C strings initialization.
983 * lisp.h (make_pure_string): Fix prototype.
984 (build_pure_c_string): New function, defined as static inline. This
985 provides a better opportunity to optimize away calls to strlen when
986 the function is called with compile-time constant argument.
987 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
988 argument, adjust users accordingly. Use build_pure_c_string where
989 appropriate.
990 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
991 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
992 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
993
994 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
995
996 Avoid calls to strlen in miscellaneous functions.
997 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
998 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
999 * lread.c (openp): Likewise.
1000
1001 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1002
1003 Avoid calls to strlen in path processing functions.
1004 * fileio.c (file_name_as_directory): Add comment. Change to add
1005 srclen argument and return the length of result. Adjust users
1006 accordingly.
1007 (directory_file_name): Fix comment. Change to add srclen argument,
1008 swap 1st and 2nd arguments to obey the common convention. Adjust
1009 users accordingly.
1010 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1011
1012 2012-07-10 Glenn Morris <rgm@gnu.org>
1013
1014 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1015 Move PENDING_OUTPUT_COUNT definition to configure.
1016
1017 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1018 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1019 * s/gnu.h (DATA_START): Move definitions to configure.
1020
1021 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1022 We include usg5-4-common.h, which defines them both.
1023
1024 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1025 O_RDONLY already includes it).
1026
1027 Stop ns builds setting the EMACSLOADPATH environment variable.
1028 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1029 Now it does not set EMACSLOADPATH, just returns the load-path string.
1030 * nsterm.h: Update accordingly.
1031 * lread.c [HAVE_NS]: Include nsterm.h.
1032 (init_lread) [HAVE_NS]: Use ns_load_path.
1033 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1034
1035 2012-07-09 Glenn Morris <rgm@gnu.org>
1036
1037 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1038 since the included bsd-common.h does so.
1039
1040 Stop ns builds setting the EMACSPATH environment variable.
1041 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1042 (ns_init_paths): Do not set EMACSPATH.
1043 * nsterm.h (ns_exec_path): Add it.
1044 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:

1046
1047 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1048
1049 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1050
1051 * process.c (wait_reading_process_output): 'waitchannels' was unset
1052 when read_kbd || !NILP (wait_for_cell); fix this.
1053
1054 Add GCC-style 'const' attribute to functions that can use it.
1055 * character.h (char_resolve_modifier_mask):
1056 * keyboard.h (make_ctrl_char):
1057 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1058 (init_character_once, next_almost_prime, init_fns, init_image)
1059 (flush_pending_output, init_sound):
1060 * mem-limits.h (start_of_data):
1061 * menu.h (finish_menu_items):
1062 Add ATTRIBUTE_CONST.
1063 * emacs.c (DEFINE_DUMMY_FUNCTION):
1064 Declare the dummy function with ATTRIBUTE_CONST.
1065 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1066 Add decls with ATTRIBUTE_CONST.
1067
1068 Minor improvements to make_formatted_string.
1069 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1070 where int is good enough, as vsprintf returns an int.
1071 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1072
1073 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1074
1075 Use make_formatted_string to avoid double length calculation.

1096 * nsterm.h (ns_etc_directory): Add it.
1097 * callproc.c [HAVE_NS]: Include nsterm.h.
1098 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1099
1100 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1101
1102 Move marker debugging code under MARKER_DEBUG.
1103 * marker.c (MARKER_DEBUG): Move marker debugging code under
1104 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1105 for bootstrap with --enable-checking (~3x slowdown reported
1106 by Juanma Barranquero <lekktu@gmail.com>).
1107 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1108
1109 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1110
1111 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1112 See <http://bugs.gnu.org/11825#29>.
1113
1114 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1115
1116 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1117 has no font, use the frame's font. (Bug#11813)
1118 (display_line): Add commentary about displaying truncation glyphs
1119 on GUI frames.
1120 (produce_special_glyphs): Move here from term.c.
1121
1122 * term.c (produce_special_glyphs): Move to xdisp.c.
1123
1124 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1125 section.
1126
1127 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1128
1129 * xdisp.c (display_line): Avoid warning about implicit declaration
1130 of FRAME_FONT.
1131
1132 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1133
1134 * lisp.h: Remove empty conditional.
1135
1136 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1137
1138 * lread.c (load_path_check): Now static.
1139
1140 Fix some minor --with-ns problems found by static checking.
1141 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1142 (x_set_font) [!HAVE_X_WINDOWS]:
1143 * image.c (xpm_load_image) [HAVE_NS]:
1144 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1145 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1146 Remove unused local.
1147 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1148 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1149 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1150 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1151 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1152 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1153 Fix pointer signedness problem.
1154 * xfaces.c (FRAME_X_FONT_TABLE):
1155 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1156
1157 2012-07-07 Glenn Morris <rgm@gnu.org>
1158
1159 * lread.c (load_path_check): New function, split from init_lread.
1160 (init_lread): Reorganize. Motivation:
1161 If EMACSLOADPATH is set, check/warn about that rather than the
1162 defaults, which we are not going to use. Hence we can remove
1163 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1164 Don't warn if site-lisp directories are missing.
1165 If not installed, start from a blank load-path, since
1166 PATH_LOADSEARCH refers to the eventual installation directories.
1167
1168 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1169
1170 Support truncation and continuation glyphs on GUI frames, when
1171 fringes are disabled. (Bug#11832)
1172 * xdisp.c (init_iterator): Get dimensions of truncation and
1173 continuation glyphs even if on GUI frames. Adjust
1174 it->last_visible_x on GUI frames when the left or right fringes,
1175 or both, are absent.
1176 (start_display, move_it_in_display_line_to): Handle the case of a
1177 GUI frame without a fringe to display continuation or truncation
1178 glyphs.
1179 (insert_left_trunc_glyphs): Support GUI frames: make sure
1180 truncation glyphs overwrite enough glyphs from the current line to
1181 have sufficient space in pixels.
1182 (display_line): Support truncation and continuation glyphs on GUI
1183 frames. If some spare pixels are left on the line after inserting
1184 the truncation glyphs, fill that space with a stretch glyph of a
1185 suitably computed width.
1186
1187 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1188 produce_glyphs, to support GUI sessions.
1189
1190 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1191
1192 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1193
1194 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1195
1196 Do not require float-time's arg to fit in time_t (Bug#11825).
1197 This works better on hosts where time_t is unsigned, and where
1198 float-time is applied to the (negative) difference between two times.
1199 * editfns.c (decode_time_components): Last arg is now double *,
1200 not int *, and means to store all the result as a double, without
1201 worrying about whether the seconds part fits in time_t.
1202 All callers changed.
1203 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1204 All callers changed.
1205 (Ffloat_time): Do not fail merely because the specified time falls
1206 outside of time_t range.
1207
1208 2012-07-07 Glenn Morris <rgm@gnu.org>
1209
1210 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1213
1214 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1215
1216 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1217 Update dependencies.
1218
1219 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1220
1221 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1222
1223 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1224 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1225 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1226 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1227 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1228 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1229
1230 * xfont.c (compare_font_names): Redo to omit the need for casts.
1231
1232 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1233
1234 * xfns.c (Fx_change_window_property): Doc fix.
1235 * w32fns.c (Fx_change_window_property): Doc fix.
1236
1237 * w32fns.c (Fx_window_property): Accept the same arguments as the
1238 X Windows version. Doc fix.
1239 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1240
1241 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1242 Eli Zaretskii <eliz@gnu.org>
1243
1244 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1245 Windows-specific code from nt/config.nt moved here.
1246 Obsolete settings removed.
1247
1248 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1249
1250 * process.c: Avoid unnecessary calls to gettime.
1251 (wait_reading_process_output): Don't get the time of day
1252 when gobbling data immediately and not waiting, as there's no need
1253 for it in that case. This removes a FIXME.
1254
1255 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1256
1257 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1258 is defined (Bug#11768).
1259
1260 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1261
1262 Fix marker debugging code.
1263 * marker.c (byte_char_debug_check): Do not perform the check
1264 if buffer is not multibyte.
1265 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1266 Call byte_char_debug_check with correct arguments.

1268 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1269
1270 Compile marker debugging code only if ENABLE_CHECKING is defined.
1271 * marker.c (byte_char_debug_check, count_markers):
1272 Use only if ENABLE_CHECKING is defined.
1273 (byte_debug_flag): Remove.
1274 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1275 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1276
1277 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1278
1279 Avoid code repetition in marker-related functions.
1280 * marker.c (attach_marker): New function.
1281 (Fset_marker, set_marker_restricted, set_marker_both)
1282 (set_marker_restricted_both): Use it.
1283 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1284 Consistently rename charno to charpos.
1285 (marker_position): Add eassert.
1286 (marker_byte_position): Convert to eassert.
1287
1288 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1289
1290 Simplify list operations in unchain_overlay and unchain_marker.

1310 to avoid redundant calls to unchain_overlay.
1311 * buffer.c (drop_overlay): New function.
1312 (delete_all_overlays, Fdelete_overlay): Use it.
1313 * minibuf.c (get_minibuffer): Fix comment.
1314
1315 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1316
1317 Port to OpenBSD 5.1 amd64.
1318 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1319 This is needed for OpenBSD, and should be harmless on all BSD systems.
1320 Also, include <sys/sysctl.h>, as it should be available on all
1321 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1322 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1323 use p_pid member, not kp_proc.pid.
1324
1325 2012-07-06 Glenn Morris <rgm@gnu.org>
1326
1327 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1328
1329 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1330
1331 More xmalloc and related cleanup.
1332 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

1340 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1341 * xterm.c:
1342 Omit needless casts involving void * pointers and allocation.
1343 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1344 as the former is more robust if P's type is changed.
1345 Prefer xzalloc to xmalloc + memset 0.
1346 Simplify malloc-or-realloc to realloc.
1347 Don't worry about xmalloc returning a null pointer.

1355
1356 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1357 hscroll is larger than the line width. Fixes long and futile
1358 looping inside extend_face_to_end_of_line (on a TTY) producing
1359 glyphs that are not needed and thrown away.
1360
1361 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1362
1363 * marker.c (set_marker_restricted_both): Simplify by using
1364 clip_to_bounds.
1365
1366 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1367
1368 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1369
1370 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
1371
1372 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
1373 not defined (Bug#11768).
1374 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1375 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1376 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1377 followed by gtk_box_set_homogeneous (Bug#11768).
1378 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1379 (update_theme_scrollbar_width, xg_create_scroll_bar):
1380 Use gtk_scrollbar_new (Bug#11768).
1381 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1382 (is_box_type): New function (Bug#11768).
1383 (xg_tool_item_stale_p): Call is_box_type.
1384 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1385 with default display (Bug#11768).

1389 * xdisp.c (window_hscroll_limited): New function.
1390 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1391 coordinates when window's hscroll is set to insanely large
1392 values. (Bug#11857)
1393
1394 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

1458 Problem reported by Troels Nielsen in
1459 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1460
1461 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1462
1463 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1464 This should be fixed in a better way; see Eli Zaretskii in
1465 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1466 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1467
1468 * fileio.c (time_error_value): Rename from special_mtime.
1469 The old name's problems were noted by Eli Zaretskii in
1470 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1471
1472 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1473 This variable's comment says Emacs needs at least one GDB-visible
1474 symbol of type enum pvec_type, to work around GDB problems.
1475 The symbol's value doesn't matter.
1476
1477 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1478 that causes compilation to fail on pre-C99 compilers.
1479
1480 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

1495 (PSEUDOVECTOR_SIZE_BITS): New constant.
1496 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.

1505 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1506 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1507 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1508 abusing vector->header.next.nbytes.
1509 (live_vector_p): Use PVEC_TYPE.
1510 (mark_object): Adapt code to extract pvectype. Use switch.
1511
1512 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1513
1514 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1515 Tighten new eassert a bit.
1516
1517 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1518
1519 Fix compilation with --enable-gcc-warnings and -O1
1520 optimization level.
1521 * doprnt.c (doprnt): Change type of tem to int, initialize
1522 to avoid compiler warning. Add eassert.
1523 * search.c (simple_search): Initialize match_byte to avoid
1524 compiler warning. Add eassert.
1525
1526 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1527
1528 Avoid weird behavior with large horizontal scrolls.
1529 Without this change, for example, large hscroll values would
1530 mess up Emacs's display on Fedora 15 x86, presumably due to
1531 overflows in int calculations in the display code.
1532 Also, if buffers had long lines, Emacs would freeze.
1533 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1534 (set_window_hscroll): New function, containing the old guts of
1535 Fset_window_hscroll. Return the clipped value.
1536 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1537 This avoids the need to check against PTRDIFF_MAX.
1538
1539 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1540
1541 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

1544
1545 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1546
1547 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1548 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1549 since GCC 4.4.6 issues a bogus warning for them.
1550
1551 Fix bugs in file timestamp newness comparisons.
1552 * fileio.c (Ffile_newer_than_file_p):
1553 * lread.c (Fload): Use full timestamp resolution of files,
1554 not just the 1-second resolution, so that files that are only
1555 slightly newer still count as newer.
1556 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1557 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1558
1559 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1560
1561 * fileio.c: Improve handling of file time marker. (Bug#11852)

1567
1568 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1569 marker for non-existing file. (Bug#11852)
1570
1571 2012-07-03 Glenn Morris <rgm@gnu.org>
1572
1573 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1574 and did not make it into globals.h).
1575
1576 2012-07-03 Tom Tromey <tromey@redhat.com>
1577

1621
1622 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1623 values which aren't power of 2.
1624 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1625 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1626 accordingly.
1627
1628 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1629
1630 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

1635
1636 * alloc.c (allocate_vector_block): Remove redundant
1637 calls to mallopt if DOUG_LEA_MALLOC is defined.

1640
1641 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1642
1643 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES

1648
1649 Cleanup basic buffer management.
1650 * buffer.h (struct buffer): Change layout to use generic vector

1659 * alloc.c (allocate_buffer): Adjust to match new layout of
1660 struct buffer. Fix comment.

1663 Lisp area of struct buffer.
1664 (mark_object): Use it. Adjust marking of misc objects
1665 and related comments.
1666
1667 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1668
1669 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1670 wrapper that is not needed because the wrapped code is a no-op (zero
1671 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1672 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1673
1674 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1675
1676 * alloc.c (mark_buffer): Simplify. Remove prototype.
1677 (mark_object): Add comment. Reorganize marking of vector-like
1678 objects. Use CHECK_LIVE for all vector-like objects except buffers
1679 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1680 redundant calls to mark_vectorlike for bool vectors.
1681
1682 2012-06-30 Glenn Morris <rgm@gnu.org>
1683
1684 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1685
1686 * epaths.in (PATH_SITELOADSEARCH): New.
1687 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1688 This is rather than relying on --enable-locallisppath elements
1689 having "site-lisp" in their names. (Bug#10208#25, 11658)

1694
1695 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1696
1697 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1698 (pselect) [!MS_DOS]: Redirect to sys_select.
1699
1700 * sysdep.c: Don't include dos.h and dosfns.h.
1701
1702 * process.c (sys_select):
1703 * msdos.c (sys_select): Accept one more argument and ignore it.
1704
1705 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1706 adapt data types and code to that.
1707
1708 * dosfns.c:
1709 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1710 which clashes with the gnulib function of the same name.
1711
1712 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1713

1726
1727 * w32.c (getwd): Adjust commentary about startup_dir.
1728 (init_environment): Always call sys_access, even in non-MSVC
1729 builds. Don't chdir to the directory of the Emacs executable.
1730 This undoes code from 1997 which was justified by the need to
1731 "avoid conflicts when removing and renaming directories". But its
1732 downside was that every relative file name was being interpreted
1733 relative to the directory of the Emacs executable, which can never
1734 be TRT. In particular, it broke sys_access when called with
1735 relative file names.
1736 (sys_access): Map GetLastError to errno.

1930 Use sprintf return value instead of invoking strlen on result.
1931 In the old days this wasn't portable, since some sprintf
1932 implementations returned char *. But they died out years ago and
1933 Emacs already assumes sprintf returns int.
1934 Similarly for float_to_string.
1935 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

1943 Use sprintf or float_to_string result to avoid need to call strlen.
1944 * data.c (Fnumber_to_string):

1946 * lisp.h, print.c (float_to_string): Now returns int length.
1947 * term.c (produce_glyphless_glyph):
1948 Use sprintf result rather than recomputing it.

2121 Support higher-resolution time stamps (Bug#9000).
2122 The time stamps are only nanosecond-resolution at the C level,
2123 since that's the best that any real-world system supports now.
2124 But they are picosecond-resolution at the Lisp level, as that's
2125 easy, and leaves room for future OS improvements.
2126

2134 now provides it if it's absent.
2135 (start_atimer): Port to higher-res time stamps.
2136 Check for time stamp overflow. Don't get current time more
2137 often than is needed.
2138
2139 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2140 Include systime.h, not time.h.

2164 do that.
2165
2166 * fileio.c: Include <stat-time.h>
2167 (Fcopy_file): Copy higher-resolution time stamps.
2168 Prefer to set the time stamp via a file descriptor if that works.

2185 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2186 Port to higher-resolution time stamps. Do not assume time_t is signed.

2189 (timer_check_2): Use it.
2190
2191 * nsterm.m (select_timeout, timeval_subtract): Remove.
2192 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,

2195 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2196 * nsterm.h (ns_select): Adjust prototype.

2219
2220 * sysdep.c: Include utimens.h. Don't include utime.h
2221 or worry about struct utimbuf; gnulib does that for us now.
2222 (gettimeofday): Remove; gnulib provides a substitute.
2223 (make_timeval): New function.
2224 (set_file_times): Now sets ns-resolution time stamps.
2225 New arg FD; all uses changed.
2226 (time_from_jiffies, ltime_from_jiffies, get_up_time)

2228 Now returns ns-resolution time stamp. All uses changed.
2229 Check for time stamp overflow.
2230

2232 provides a substitute now.
2233
2234 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2235 since it guarantees struct timespec.
2236 (EMACS_TIME): Now struct timespec, so that we can support
2237 ns-resolution time stamps.
2238 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2239 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2240 (EMACS_USECS): Remove.
2241 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2242 so multiply the arg by 1000 before storing it.
2243 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2244 New macros.

2252 (make_timeval, make_lisp_time, decode_time_components): New decls.
2253 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2254 that it mishandled time_t overflow. You can't compare by subtracting!
2255 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2256 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

2267 (w32_get_internal_run_time):
2268 Port to higher-resolution Emacs time stamps.
2269 (ltime): Now accepts single 64-bit integer, as that's more convenient
2270 for callers.
2271
2272 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2273
2274 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2275 for compatibility with pselect. Support ns-resolution time stamps.
2276

2278
2279 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2280 Check for time stamp overflow, and support ns-resolution time stamps.
2281
2282 * xterm.c: Don't include sys/time.h; gnulib does that for us now.

2284 (timeval_subtract): Remove; no longer needed.
2285 (XTflash, XTring_bell, x_wait_for_event):
2286 Port to ns-resolution time stamps. Don't assume time_t is signed.

2295 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2296 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2297 staticidx goes up to 1597 out of 1600 = 0x640.)
2298
2299 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2300
2301 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

2311 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
2312 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2313 access to `contents' member of Lisp_Vector objects with AREF and ASET
2314 where appropriate.

2325 Callers changed.
2326 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2327 since tty frames can be explicitly named.
2328 (prepare_menu_bars): Likewise.
2329
2330 * term.c (Ftty_top_frame): New function.
2331
2332 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

2334 Port byte-code-meter to modern targets.
2335 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2336 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2337 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2338 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2339 (METER_1, METER_2): Simplify.
2340

2350 (Vkill_buffer_query_functions): In doc-string say that functions
2351 run by this hook should not change the current buffer.
2352
2353 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2354
2355 Fix recently-introduced process.c problems found by static checking.

2374
2375 * lisp.h (eassert): Assume C89 or later.
2376 This removes the need for CHECK.
2377 (CHECK): Remove. Its comments about always evaluating its
2378 argument were confusing, as 'eassert' typically does not evaluate
2379 its argument.
2380
2381 * coding.c (produce_chars): Use ptrdiff_t, not int.
2382
2383 * xterm.c (x_draw_underwave): Check for integer overflow.

2476
2477 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.

2554
2555 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
2556
2557 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2558 * alloc.c (make_number) [!defined make_number]:
2559 Remove, as lisp.h always defines this now.
2560 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
2561 (roundup_size): Verify that it is a power of 2.
2562 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
2563 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
2564 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
2565 -DUSE_LSB_TAG=0, to override the automatically-selected default.
2566 USE_LSB_TAG now is always defined to be either 0 or 1.
2567 All uses changed.
2568 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2569 code works fine either way, and efficiency is not a concern here,
2570 as the union type is for debugging, not for production.
2571 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2572 Use an inline function on all platforms when using the union type,
2573 since this is simpler and 'static inline' can be used portably
2574 within Emacs now.
2575 (LISP_INITIALLY_ZERO): New macro.
2576 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
2577 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

2614 2012-06-11 Chong Yidong <cyd@gnu.org>
2615
2616 * image.c (imagemagick_load_image): Implement transparency.

2638
2639 * dispextern.h: Replace unused TTY_CAP_BLINK with TTY_CAP_ITALIC.
2640 (struct face): Remove unused fields tty_dim_p, tty_blinking_p, and
2641 tty_alt_charset_p. Add tty_italic_p.
2642
2643 2012-06-09 Michael Albinus <michael.albinus@gmx.de>

2657 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
2658
2659 * xdisp.c (vmessage): Treat frame message as multibyte.
2660 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2661 would generate the diagnostic "Making \302\247 buffer-local while
2662 let-bound!".
2663
2664 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2665
2666 * dispnew.c (showing_window_margins_p): Undo last change, which
2667 was done due to an inadvertent commit.
2668 (adjust_frame_glyphs_for_frame_redisplay): Do call
2669 showing_window_margins_p.

2680 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2681
2682 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2683
2684 * alloc.c (allocate_vectorlike): Fix last change.

2687
2688 Block-based vector allocation of small vectors.
2689 * lisp.h (struct vectorlike_header): New field `nbytes',
2690 adjust comment accordingly.

2692 to denote vector blocks. Adjust users (live_vector_p,
2693 mark_maybe_pointer, valid_lisp_object_p) accordingly.
2694 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
2695 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

2708 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
2709 (init_alloc_once): Add call to init_vectors.
2710
2711 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>

2714
2715 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2716
2717 * doprnt.c (doprnt): Truncate multibyte char correctly.
2718 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2719 would mishandle a string argument "Xc" if X was a multibyte
2720 character of length 2: it would truncate after X's first byte
2721 rather than including all of X.
2722
2723 2012-06-06 Chong Yidong <cyd@gnu.org>
2724
2725 * buffer.c (word_wrap): Doc fix.

2748 2012-06-03 Chong Yidong <cyd@gnu.org>
2749
2750 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
2751 (note_mode_line_or_margin_highlight): If there is no help echo,
2752 use mode-line-default-help-echo. Handle the case where the mouse
2753 position is past the end of the mode line string.
2754
2755 * buffer.c (buffer_local_value_1): New function, split from
2756 Fbuffer_local_value; can return Qunbound.

2771
2772 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2773
2774 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2775 Convert pctcpu and pctmem to Lisp float properly.
2776 Let the compiler fold better, as 100.0/0x8000 is exact.
2777
2778 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2779
2780 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

2786
2787 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2788
2789 For a 'struct window', replace some Lisp_Object fields to
2790 bitfields where appropriate, remove unused fields.
2791 * window.h (struct window): Remove unused 'last_mark_x' and
2792 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2793 change it's type from Lisp_Object to bitfield.
2794 Change type of 'force_start', 'optional_new_start',
2795 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2796 fields from Lisp_Object to bitfield. Adjust users accordingly.
2797
2798 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2799
2800 Pacify gcc -Wdouble-precision when using Xaw.

2802 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2803 Use 'float' consistently, rather than 'float' in most places
2804 and 'double' in a couple of places.
2805
2806 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2807
2808 * xdisp.c (handle_stop): Detect whether we have overlay strings
2809 loaded by testing it->current.overlay_string_index to be
2810 non-negative, instead of checking whether n_overlay_strings is
2811 positive. (Bug#11587)
2812
2813 2012-05-31 Chong Yidong <cyd@gnu.org>
2814
2815 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

2818
2819 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2820
2821 * search.c (search_buffer): Remove calls to
2822 r_alloc_inhibit_buffer_relocation, as it is now called by
2823 maybe_unify_char, which was the cause of relocation of buffer text
2824 in bug#11519.
2825
2826 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2827
2828 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2829 for the duration of call to load_charset, to avoid problems with
2830 callers of maybe_unify_char that access buffer text through C
2831 pointers.
2832
2833 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2834 decrement the inhibition flag, instead of just setting or
2835 resetting it.

2838
2839 Remove obsolete '#define static' cruft.
2840 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2841 This #undef was "temporary" in 2000; it is no longer needed

2844 (gray_bitmap_bits): Remove; no longer needed.
2845 All uses replaced with definiens.

2850 Clean up __executable_start, monstartup when --enable-profiling.
2851 The following changes affect the code only when profiling.
2852 * dispnew.c (__executable_start): Rename from safe_bcopy.
2853 Define only on platforms that need it.
2854 * emacs.c: Include <sys/gmon.h> when profiling.
2855 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2856 (__executable_start): Remove decl, since lisp.h does it now.
2857 (safe_bcopy): Remove decl; no longer has that name.
2858 (main): Coalesce #if into single bit of code, for simplicity.
2859 Cast pointers to uintptr_t, since standard libraries want integers
2860 and not pointers.
2861 * lisp.h (__executable_start): New decl.
2862
2863 2012-05-31 Glenn Morris <rgm@gnu.org>

2889 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2890 Bug#9642, but explicitly check that the buffer the overlay would
2891 be moved to is live and rearrange lines to make sure that errors
2892 will not put the overlay in an inconsistent state.
2893 (Fdelete_overlay): Cosmetics.
2894
2895 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2896
2897 * w32term.c (my_bring_window_to_top): New function.
2898 (x_raise_frame): Use handle returned by DeferWindowPos, which

2900 Call my_bring_window_to_top instead of my_set_foreground_window.
2901 (Bug#11513)
2902
2903 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP

2910
2911 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2912 This avoids undefined behavior that might cause the eassert
2913 to not catch an out-of-range value.
2914
2915 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2916

2930
2931 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2932 Only r_alloc_inhibit_buffer_relocation needed to be added;
2933 the others were already declared.
2934
2935 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2936 before checking whether it's out of range. Put the check inside
2937 eassert. See
2938 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2939

2949
2950 * buffer.c [REL_ALLOC]: Remove prototypes of

2952 they are now on lisp.h.
2953
2954 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2955
2956 * search.c (search_buffer): Use it to inhibit relocation of buffer
2957 text while re_search_2 is doing its job, because re_search_2 is
2958 passed C pointers to buffer text. (Bug#11519)
2959
2960 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2961 Update value to 24.
2962
2963 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2964 state after an additional call to move_it_in_display_line_to, keep
2965 the values of it->max_ascent and it->max_descent found for the

2972
2973 Fix coding-related core dumps with gcc -ftrapv.
2974 The code was computing A - B, where A and B are pointers, and B is
2975 random garbage. This can lead to core dumps on platforms that
2976 have special pointer registers, and it also leads to core dumps on
2977 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2978 A - B only when B is initialized properly.
2979 * coding.c (coding_set_source, coding_set_destination): Return void.
2980 (coding_change_source, coding_change_destinations): New functions,
2981 with the old behaviors of coding_set_source and coding_set_destination.

2998
2999 * w32inevt.c: Include termchar.h and window.h.
3000 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3001 moves, call note_mouse_highlight. If help_echo changed, call
3002 gen_help_event to produce help-echo message in the echo area.
3003 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3004 highlight info.
3005
3006 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>

3029 (allocate_pseudovector):
3030 Use int, not EMACS_INT, where int is wide enough.
3031 (inhibit_garbage_collection, Fgarbage_collect):
3032 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3050 (Foverlay_recenter, last_overlay_modification_hooks_used)
3051 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3052 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3053 (validate_region): Omit unnecessary test for b <= e,
3054 since that's guaranteed by the previous test.
3055 (adjust_overlays_for_delete): Avoid pos + length overflow.
3056 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3057 (report_overlay_modification):
3058 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3059 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3060 Omit pointer cast, which isn't needed anyway, and doesn't work
3061 after the EMACS_INT -> ptrdiff_t change.
3062 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3063 * buffer.h: Adjust decls to match defn changes elsewhere.

3068 not int, to avoid needless 32-bit limit on 64-bit hosts.
3069 (exec_byte_code): Use tighter memory-full test, one that checks
3070 for alloca overflow. Don't compute the address of the object just
3071 before an array, as that's not portable. Use EMACS_INT, not
3072 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3073 * callint.c (Fcall_interactively):
3074 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3075 * callproc.c (call_process_kill, Fcall_process):

3086 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3087 (casify_object): Avoid integer overflow when overallocating buffer.
3088 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3089 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

3091 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3092 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3093 integers are now checked earlier. All uses replaced with XINT.
3094 (ccl_driver):
3095 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3096 For CCL_MapSingle, check that content and value are in int range.

3098 Check that Vcode_version_map_vector is a vector.
3099 (resolve_symbol_ccl_program): Check that vector header is in range.
3100 Always copy the vector, so that we can check its contents reliably
3101 now rather than having to recheck each instruction as it's being
3102 executed. Check that vector words fit in 'int'.
3103 (ccl_get_compiled_code, Fregister_ccl_program)
3104 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3105 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3106 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3107 contents are in range.
3108 (Fccl_execute_on_string): Check that status is in range.
3109 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3110 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3111 Accept and return EMACS_INT, not int, because callers can pass values
3112 out of 'int' range.

3118 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3119 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3120 avoid mishandling large integers.

3127 Don't assume fixnum fits in int.
3128 (load_charset_map_from_vector, Fmap_charset_chars):

3130 (Fdefine_charset_internal): Check ranges here, more carefully.
3131 Don't rely on undefined behavior with signed left shift overflow.
3132 Don't assume unsigned int fits into fixnum, or that fixnum fits
3133 into unsigned int. Don't require max_code to be a valid fixnum;
3134 that's not true for gb10830 4-byte on a 32-bit host. Allow
3135 invalid_code to be a cons, for the same reason. Require code_offset
3136 to be a character. Avoid int overflow if max_char is close
3137 to INT_MAX.
3138 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3139 this is intended anyway and avoids some undefined behavior.
3140 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3141 INDEX_TO_CODE_POINT, as that's what it expects.
3142 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3143 * charset.h (DECODE_CHAR): Return int, not unsigned;
3144 this is what was intended anyway, and it avoids undefined behavior.
3145 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3146 integer-overflow issues.
3147 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3148 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3149 where the argument is EMACS_INT, and this behavior is not intended.
3150 * chartab.c (Fmake_char_table, Fset_char_table_range)
3151 (uniprop_get_decoder, uniprop_get_encoder):
3152 Don't assume fixnum fits in int.
3153 * cmds.c (move_point): New function, that does the gist of
3154 Fforward_char and Fbackward_char, but does so while checking
3155 for integer overflow more accurately.
3156 (Fforward_char, Fbackward_char): Use it.
3157 (Fforward_line, Fend_of_line, internal_self_insert)
3158 (internal_self_insert):
3159 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3160 Fix a FIXME, by checking for integer overflow when calculating
3161 target_clm and actual_clm.

3196 Don't access memory outside of the args array.
3197 (Fdefine_coding_system_internal): Check for charset-id overflow.

3845 This directory predates autoconf and is no longer needed nowadays.
3846 Move its few remaining bits of functionality to where they're needed.
3847 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

3857 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3858 (BITS_PER_EMACS_INT): New constants, replacing
3859 what used to be in config.h, but not useful in #if.
3860 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3861 define them any more.

3870 Move here from removed file m/intel386.h.

3873
3874 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>

3930 (bug#10145, bug#11381).
3931
3932 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3933
3934 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3935

3937
3938 * lread.c (init_obarray): Declare Qt and Qnil as special.
3939

3943 Put "libexec" before "bin", for the sake of init_callproc_1.
3944
3945 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3946
3947 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3948
3949 * unexaix.c: Port to more-recent AIX compilers.
3950 (report_error, report_error_1, make_hdr, copy_sym)
3951 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3952 Make arguments const char *, not char *, to avoid violations of C
3953 standard and to fix some AIX warnings reported by Gilles Pion.
3954
3955 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3956
3957 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3958 already have overlays loaded.
3959 (handle_single_display_spec): Before returning without displaying
3960 fringe bitmap, synchronize the bidi iterator with the main display
3961 iterator, by calling iterate_out_of_display_property.
3962 (iterate_out_of_display_property): Detect buffer iteration by
3963 testing that it->string is a Lisp string.
3964 (get_next_display_element): When the current object is exhausted,
3965 and there's something on it->stack, call set_iterator_to_next to
3966 proceed with what's on the stack, instead of returning zero.
3967 (set_iterator_to_next): If called at the end of a Lisp string,
3968 proceed to consider_string_end without incrementing string
3969 position. Don't increment display vector index past the end of
3970 the display vector. (Bug#11417)
3971 (pos_visible_p): Don't report a position visible when move_it_to
3972 stopped at the last line of window, which happens to be scanned
3973 backwards by the bidi iteration. (Bug#11464)
3974
3975 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3976
3977 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3978 and right-margin display specs even if the spec is invalid or we
3979 are on a TTY, and thus unable to display on the fringes.
3980 That's because the text with the property will not be displayed anyway,
3981 so we need to signal to the caller that this is a "replacing"
3982 display spec. This fixes display when the spec is invalid or we
3983 are on a TTY.
3984
3985 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3986
3987 * unexaix.c (make_hdr): Fix typo in prototype.

4026
4027 2012-05-10 Dave Abrahams <dave@boostpro.com>
4028
4029 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4030 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)

4032 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4033
4034 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4035 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.

4039 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4040
4041 Untag more efficiently if USE_LSB_TAG.
4042 This is based on a proposal by YAMAMOTO Mitsuharu in
4043 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4044 For an admittedly artificial (nth 8000 longlist) benchmark on
4045 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4046 Emacs's overall text size by 1%.
4047 * lisp.h (XUNTAG): New macro.
4048 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4049 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4050 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4051 * eval.c (Fautoload):
4052 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4053 * frame.h (XFRAME): Use XUNTAG.
4054
4055 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4056 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4057 Remove unportable assumptions about print widths of types like
4058 dbus_uint32_t.
4059 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4060 intptr_t when converting between pointer and integer, to avoid GCC
4061 warnings about wrong width.
4062
4063 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4064
4065 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4066 stack for each reader_thread, instead of defaulting to 8MB
4067 determined by the linker. This avoids failures in creating
4068 subprocesses on Windows 7, see the discussion in this thread:
4069 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4070
4071 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4072
4073 Fix up display of the *Minibuf-0* buffer in the mini window.
4074 * keyboard.c (read_char): Don't clear the echo area if there's no
4075 message to clear.
4076 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4077 contents of *Minibuf-0*) if there's no message displayed in its stead.
4078
4079 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4080
4081 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4082 batch mode.
4083
4084 2012-05-06 Chong Yidong <cyd@gnu.org>
4085
4086 * lisp.mk (lisp): Update.
4087
4088 2012-05-05 Jim Meyering <meyering@redhat.com>
4089
4090 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4091
4092 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4093
4094 * data.c (PUT_ERROR): New macro.
4095 (syms_of_data): Use it. Add new error type `user-error'.
4096 * undo.c (user_error): New function.
4097 (Fprimitive_undo): Use it.
4098 * print.c (print_error_message): Adjust print style for `user-error'.
4099 * keyboard.c (user_error): New function.
4100 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4101
4102 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4103
4104 Do not limit current-time-string to years 1000..9999.
4105 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4106 (Fcurrent_time_string): Support any year that is supported by the
4107 underlying localtime representation. Don't use asctime, as it
4108 has undefined behavior for years outside the range -999..9999.
4109
4110 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4111
4112 Fix race conditions involving setenv, gmtime, localtime, asctime.
4113 Without this fix, interrupts could mess up code that uses these
4114 nonreentrant functions, since setting TZ invalidates existing
4115 tm_zone or tzname values, and since most of these functions return
4116 pointers to static storage.
4117 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4118 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4119 Grow the critical sections to include not just invoking
4120 localtime/gmtime, but also accessing these functions' results
4121 including their tm_zone values if any, and any related TZ setting.
4122 (format_time_string): Last arg is now struct tm *, not struct tm **,
4123 so that the struct tm is saved in the critical section.
4124 All callers changed. Simplify allocation of initial buffer, partly
4125 motivated by the fact that memory allocation needs to be outside
4126 the critical section.
4127
4128 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4129
4130 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4131 with RESET_INTERVAL.
4132
4133 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4134 Remove duplicated buffer name initialization.
4135
4136 2012-05-02 Jim Meyering <jim@meyering.net>
4137
4138 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4139
4140 * xfns.c (x_window): Use xstrdup (Bug#11375).
4141
4142 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4143
4144 * xdisp.c (pos_visible_p): If already at a newline from the
4145 display string before the 'while' loop, don't walk back the glyphs
4146 from it3.glyph_row. Solves assertion violation when the display
4147 string begins with a newline (egg.el). (Bug#11367)
4148
4149 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4150
4151 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4152 Move to simple.el.
4153
4154 2012-05-01 Glenn Morris <rgm@gnu.org>
4155
4156 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4157 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4158 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4159 All were removed before 23.1.
4160
4161 * dispnew.c: Remove HAVE_LIBNCURSES test;
4162 it is always true on relevant platforms.
4163
4164 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4165 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4166
4167 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4168
4169 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4170
4171 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4172 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4173 Remove.
4174
4175 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4176
4177 Do not avoid creating empty evaporating overlays (Bug#9642).
4178 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4179 That is, do not delete an evaporating overlay if it becomes
4180 empty after its bounds are adjusted to fit within its buffer.
4181 This fix caused other problems, and I'm reverting it until we get
4182 to the bottom of them.
4183
4184 2012-04-27 Chong Yidong <cyd@gnu.org>
4185
4186 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4187
4188 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4189
4190 * xdisp.c (pos_visible_p): If the window start position is beyond
4191 ZV, start the display from buffer beginning. Prevents assertion
4192 violation in init_iterator when the minibuffer window is scrolled
4193 via the scroll bar.
4194
4195 * window.c (window_scroll_pixel_based): Likewise.
4196
4197 2012-04-27 Chong Yidong <cyd@gnu.org>
4198
4199 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4200
4201 2012-04-27 Glenn Morris <rgm@gnu.org>
4202
4203 * fileio.c (Fcopy_file, Fset_file_selinux_context):

4205
4206 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4207
4208 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4209 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4210
4211 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4212
4213 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4214 display element, check also the underlying string or buffer
4215 character. (Bug#11341)
4216
4217 * w32menu.c: Include w32heap.h.
4218 (add_menu_item): If the call to AppendMenuW (via
4219 unicode_append_menu) fails, disable Unicode menus only if we are
4220 running on Windows 9X/Me.
4221
4222 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4223
4224 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4225 (xgetint): Add missing shift for LSB tags.
4226
4227 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4228
4229 * keyboard.c (read_char): Don't wipe echo area for select window
4230 events: These might get delayed via `mouse-autoselect-window'
4231 (Bug#11304).
4232
4233 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4234
4235 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4236 manipulation of :loaded-from data.
4237
4238 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

4240 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4241 now a cons (bug#11311).
4242
4243 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4244
4245 Do not create empty overlays with the evaporate property (Bug#9642).
4246 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4247 if it becomes empty after its bounds are adjusted to fit within
4248 its buffer. Without this fix, in a nonempty buffer (let ((o
4249 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4250 yields an empty overlay that has the evaporate property, which is
4251 not supposed to happen.
4252
4253 Fix minor GTK3 problems found by static checking.
4254 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4255 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4256 (struct _EmacsFixedClass, emacs_fixed_get_type):

4259 (emacs_fixed_class_init): Omit unused local.
4260 (emacs_fixed_child_type): Remove; unused.

4270
4271 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4272
4273 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4274 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4275 (__malloc_size_t, __malloc_ptrdiff_t):
4276 Remove. All uses removed, replaced by the definiens if needed,
4277 since we can assume C89 or better now.
4278 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4279 (protect_malloc_state, align, get_contiguous_space)
4280 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

4286 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
4287 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
4288 Define using prototypes, not old style.
4289 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
4290 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
4291 (align): Don't assume that signed integer overflow wraps around.
4292 Omit unused local var.
4293 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

4352
4353 * alloc.c: Handle unusual debugging option combinations.
4354 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4355 since the two debugging options are incompatible.
4356 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4357 is defined.
4358 (mem_init, mem_insert, mem_insert_fixup):
4359 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

4389 * print.c (print_preprocess): Only check print_depth if print-circle
4390 is nil.

4430 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
4431 -Wunused-result, -Wunused-variable. This should go away once
4432 the Emacs and Gnulib regex code is merged.

4454 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4455 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4456 (NEED_MEM_INSERT): New macro.
4457 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4458 Remove one incorrect comment and fix another.

4461 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
4462 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
4463 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
4464 (r_alloc_sbrk): Now static.
4465
4466 Improve ralloc.c interface checking.
4467 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
4468 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
4469 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
4470 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
4471 [REL_ALLOC]: ... to here, to check interface.
4472 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4473 Remove decls. This fixes an "It stinks!".

4486 (MARKER_BLOCK_SIZE, struct marker_block): Use union
4487 aligned_Lisp_Misc instead of union Lisp_Misc.
4488 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
4489
4490 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
4491
4492 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4493 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4494 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4495 * s/netbsd.h, s/sol2-6.h:
4496 Remove definition of GC_MARK_STACK, since the default now works.
4497 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4498 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4499 no longer the default.
4500 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4501
4502 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
4503
4504 * lread.c (lisp_file_lexically_bound_p):

4508
4509 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

4524
4525 2012-04-11 Daniel Colascione <dancol@dancol.org>
4526
4527 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4528 against is gone. It's better to use vfork now so that when Cygwin
4529 gains a new, working vfork, we use it automatically (bug#10398).
4530
4531 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4532

4552 being loaded (bug#10424).
4553
4554 2012-04-09 Glenn Morris <rgm@gnu.org>
4555
4556 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4557 not just in the obarray, before snarfing them. (Bug#11036)
4558
4559 * Makefile.in ($(leimdir)/leim-list.el):
4560 Pass EMACS rather than BUILT_EMACS.
4561
4562 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
4563
4564 * process.c (make_process):
4565 * process.h: Add integer `gnutls_handshakes_tried' member to
4566 process struct.
4567
4568 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
4569 Add convenience `GNUTLS_LOG2i' macro.
4570
4571 * gnutls.c (gnutls_log_function2i): Convenience log function.
4572 (emacs_gnutls_read): Use new log functions,
4573 `gnutls_handshakes_tried' process member, and
4574 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4575 attempts per process (connection).
4576
4577 2012-04-09 Chong Yidong <cyd@gnu.org>
4578
4579 * eval.c (Fuser_variable_p, user_variable_p_eh)
4580 (lisp_indirect_variable): Functions deleted.
4581 (Fdefvar): Caller changed.
4582
4583 * callint.c (Finteractive, Fcall_interactively):
4584 * minibuf.c (Fread_variable): Callers changed.
4585
4586 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4587
4588 * xdisp.c (set_cursor_from_row): If the display string appears in
4589 the buffer at position that is closer to point than the position
4590 after the display string, display the cursor on the first glyph of
4591 the display string. Fixes cursor display when a 'display' text
4592 property immediately follows invisible text. (Bug#11094)
4593
4594 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4595
4596 composite.c: use 'double' consistently
4597 * composite.c (get_composition_id): Use 'double' consistently
4598 instead of converting 'float' to 'double' and vice versa; this is
4599 easier to understand and avoids a GCC warning.
4600
4601 2012-04-09 Glenn Morris <rgm@gnu.org>
4602
4603 * Makefile.in: Generate leim-list with bootstrap-emacs, in

4623 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4624
4625 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
4626 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4627 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4628 objects, as mark_maybe_pointer will catch them otherwise.
4629 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4630 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
4631
4632 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4633
4634 Fix typo that broke non-Windows builds.
4635 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

4637 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4638
4639 Support building on MS-Windows with libxml2.
4640

4647 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
4648 [!WINDOWSNT]: New macros.
4649 (init_libxml2_functions, libxml2_loaded_p): New functions.
4650 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4651 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4652 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4653 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4654 linked in).
4655 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4656 Call init_libxml2_functions before calling libxml2 functions.
4657 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4658
4659 * emacs.c: Don't include libxml/parser.h.
4660 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4661 xmlCleanupParser directly.
4662
4663 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4664
4665 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4666
4667 * indent.c (Fvertical_motion): If there is a display string at
4668 point, use it.vpos to compute how many lines to backtrack after
4669 move_it_to point. (Bug#11133)
4670
4671 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4672
4673 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4674 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4675 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4676 macros related to unification of CJK characters. For the details,
4677 see the discussion following the message here:
4678 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4679
4680 2012-04-04 Chong Yidong <cyd@gnu.org>
4681
4682 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4683
4684 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4685
4686 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

4690
4691 * w32menu.c (is_simple_dialog): Properly check lisp types.
4692 (Bug#11141)
4693
4694 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4695
4696 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4697 position we get to after a call to move_it_to fails the
4698 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4699 only if we wind up in a string from display property. (Bug#11063)
4700
4701 * window.c (Fdelete_other_windows_internal): Invalidate the row
4702 and column information about mouse highlight, so that redisplay
4703 restores it after reallocating the glyph matrices. (Bug#7464)
4704
4705 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4706 string comes from a `display' text property, use the buffer
4707 position of that property as if we actually saw that position in
4708 the row's glyphs.
4709 (move_it_by_lines): Remove the assertion that
4710 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4711 violated when there's a before-string at the beginning of a line.
4712 (Bug#11063)
4713
4714 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4715
4716 * xdisp.c (append_space_for_newline): If the default face was
4717 remapped, use the remapped face for the appended newline.
4718 (extend_face_to_end_of_line): Use the remapped default face for
4719 extending the face to the end of the line.
4720 (display_line): Call extend_face_to_end_of_line when the default
4721 face was remapped. (Bug#11068)
4722
4723 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4724
4725 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4726
4727 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4728

4736 2012-03-26 Kenichi Handa <handa@m17n.org>
4737
4738 * dispextern.h (struct glyph): Fix previous change. Change the
4739 bit length of glyphless.ch to 25 (Bug#11082).
4740
4741 2012-03-26 Chong Yidong <cyd@gnu.org>
4742
4743 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4744 (command_loop_1): Use it; inhibit selection update for
4745 handle-select-window too (Bug#8996).
4746
4747 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4748
4749 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4750
4751 2012-03-25 Kenichi Handa <handa@m17n.org>
4752
4753 * dispextern.h (struct glyph): Change the bit length of
4754 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4755
4756 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4757
4758 * s/ms-w32.h (tzname): Include time.h before redirecting to
4759 _tzname. Fixes the MSVC build. (Bug#9960)
4760
4761 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4762
4763 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4764 characters.

4768
4769 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4770
4771 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4772 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4773 when fetching a multibyte character consumes more bytes than
4774 CHAR_BYTES returns, due to unification of CJK characters in
4775 string_char. (Bug#11073)
4776
4777 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4778
4779 * process.c (wait_reading_process_output): Handle pty disconnect
4780 by refraining from sending oneself a SIGCHLD (bug#10933).

4790
4791 2012-03-21 Chong Yidong <cyd@gnu.org>
4792

4804 to reflect default non-nil value of redisplay-dont-pause.
4805
4806 2012-03-19 Kenichi Handa <handa@m17n.org>
4807
4808 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4809 it fit in a valid range (Bug#11003).
4810
4811 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4812
4813 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4814 that is not from display property, accept the row as a "cursor
4815 row" if one of the string's character has a non-nil `cursor'
4816 property. Fixes cursor positioning when there are newlines in
4817 overlay strings, e.g. in icomplete.el. (Bug#11035)
4818
4819 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4820
4821 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4822
4823 2012-03-12 Chong Yidong <cyd@gnu.org>
4824
4825 * eval.c (inhibit_lisp_code): Rename from
4826 inhibit_window_configuration_change_hook; move from window.c.
4827
4828 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4829 * window.c (run_window_configuration_change_hook)
4830 (syms_of_window): Callers changed.
4831
4832 2012-03-11 Chong Yidong <cyd@gnu.org>
4833
4834 * keymap.c (Fkey_description): Doc fix (Bug#9700).
4835
4836 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
4837
4838 2012-03-10 Chong Yidong <cyd@gnu.org>
4839
4840 * frame.c (other_visible_frames): Don't assume the selected frame
4841 is visible (Bug#10955).

4846
4847 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4848
4849 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4850 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4851 zero (Bug#10954).
4852
4853 2012-03-03 Glenn Morris <rgm@gnu.org>
4854
4855 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
4856

4862 comments.
4863 (redisplay_window): Pass to move_it_vertically the margin in
4864 pixels, not in screen lines.
4865
4866 2012-03-02 Glenn Morris <rgm@gnu.org>
4867

4879
4880 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4881 Suggested by Stefan Monnier in
4882 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4883 * alloc.c (widen_to_Lisp_Object): New static function.
4884 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4885 and widening them to Lisp_Objects. This would work even if
4886 USE_LSB_TAG is defined and wide integers are used, which might
4887 happen in a future version of Emacs.
4888
4889 2012-02-25 Chong Yidong <cyd@gnu.org>
4890
4891 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4892 Doc fix.
4893
4894 * xselect.c (Fx_selection_exists_p): Doc fix.
4895 (x_clipboard_manager_save_all): Print an informative message
4896 before saving to clipboard manager.
4897
4898 2012-02-24 Chong Yidong <cyd@gnu.org>
4899
4900 * keyboard.c (process_special_events): Handle all X selection
4901 requests in kbd_buffer, not just the next one (Bug#8869).
4902
4903 2012-02-23 Chong Yidong <cyd@gnu.org>
4904
4905 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4906 call when setting menu-bar-lines and tool-bar-lines parameters.
4907 (unwind_create_frame_1): New helper function.
4908
4909 * window.c (inhibit_window_configuration_change_hook): New var.
4910 (run_window_configuration_change_hook): Obey it.
4911 (syms_of_window): Initialize it.
4912
4913 2012-02-22 Chong Yidong <cyd@gnu.org>
4914
4915 * xterm.c (x_draw_image_relief): Add missing type check for

4928 when computing $valmask.
4929
4930 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4931 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4932 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4933 It's useless in that case, and it can cause problems on hosts
4934 that allocate halves of EMACS_INT values separately.
4935 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4936 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4937 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4938 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4939 it avoids undefined behavior on hosts where shifting right by more
4940 than the word width has undefined behavior.
4941
4942 2012-02-19 Chong Yidong <cyd@gnu.org>
4943

4964 2012-02-15 Chong Yidong <cyd@gnu.org>
4965

4985 as that creates a dangerous corner case.
4986
4987 * window.c (Fdelete_window_internal): Invalidate the mouse
4988 highlight (Bug#9904).
4989
4990 2012-02-12 Glenn Morris <rgm@gnu.org>

5064
5065 Handle overflow when computing char display width (Bug#9496).
5066 * character.c (char_width): Return EMACS_INT, not int.
5067 (char_width, c_string_width): Check for overflow when
5068 computing the width; this is possible now that individual
5069 characters can have unbounded width. Problem introduced
5070 by merge from Emacs 23 on 2012-01-19.
5071
5072 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

5093
5094 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

5212 (Fmake_directory_internal): Use it.

5719 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
5720 Otherwise, valgrind does not work on some platforms.
5721 Problem reported by Andreas Schwab in
5722 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
5723 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5724 is set, removing the need for VIRT_ADDRESS_VARIES.
5725 (PURE_P): Use a more-efficient implementation that needs just one
5726 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5727 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5728 to 4 (xorl, subq, cmpq, setbe).
5729 * alloc.c (pure): Always extern now, since that's the
5730 VIRT_ADDR_VARIES behavior.
5731 (PURE_POINTER_P): Use a single comparison, not two, for
5732 consistency with the new puresize.h.
5733 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5734 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
5735 Remove VIRT_ADDR_VARIES no longer needed.

5739 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
5740 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5741 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5742 behave as if the cursor position were at the window margin.
5743
5744 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5745 and the cursor position is out of bounds, behave as if the cursor
5746 position were at the window margin. (Bug#10075)
5747
5748 2011-11-18 Chong Yidong <cyd@gnu.org>
5749
5750 * window.c (Fwindow_combination_limit): Make first argument

5768 hash values of the two rows. (Bug#10035)
5769 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
5770
5771 * xdisp.c (row_hash): New function, body extracted from
5772 compute_line_metrics.

5774 hash code inline.
5775
5776 * dispnew.c (verify_row_hash): Call row_hash for computing the

5816
5817 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5818
5819 * xdisp.c (display_line): Move the call to
5820 highlight_trailing_whitespace before the call to
5821 compute_line_metrics, since the latter needs to see the final
5822 faces of all the glyphs to compute ROW's hash value.
5823 Fixes assertion violations in row_equal_p. (Bug#10035)
5824
5825 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
5826
5827 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
5828 just return (bug#10044).
5829
5830 2011-11-12 Eli Zaretskii <eliz@gnu.org>
5831
5832 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5833 with user-defined heap size. Bump the default size of the temacs
5834 heap to 27MB, to avoid memory warning when running temacs.
5835 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
5836
5837 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
5838 current_matrix and desired_matrix. (Bug#9990)
5839 (verify_row_hash) [XASSERTS]: New function.

5886 Avoid some portability problems by eschewing 'extern inline' functions.
5887 The trivial performance wins aren't worth the portability hassles; see
5888 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
5889 et seq.
5890 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

5918
5919 * w32.c (check_windows_init_file): Don't look for term/w32-win.el
5920 if Vpurify_flag is non-nil. Fixes a crash when running w32 build
5921 of temacs in GUI mode.
5922
5923 2011-11-07 Martin Rudalics <rudalics@gmx.at>
5924

5937
5938 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
5939 This is also needed for porting to any host where GC_MARK_STACK is
5940 not GC_MAKE_GCPROS_NOOPS.
5941 (which_symbols): Use it.
5942
5943 2011-11-07 Kenichi Handa <handa@m17n.org>
5944
5945 * coding.c (coding_set_destination): Check coding->src_pos only

5955
5956 * xmenu.c (cleanup_widget_value_tree): New function.
5957 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

5964 (window_box_width, window_box_left, window_box_left_offset)
5965 (window_box_right, window_box_right_offset): Declare extern.
5966 Otherwise, these inline functions do not conform to C99 and
5967 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5968 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5969 * intervals.c (adjust_intervals_for_insertion)
5970 (adjust_intervals_for_deletion): Now extern, because otherwise the

5972 (static_offset_intervals): Remove.
5973 (offset_intervals): Rewrite using the old contents of
5974 static_offset_intervals. The old version didn't conform to C99
5975 because an extern inline function contained a reference to an
5976 identifier with static linkage.

5998 (Fwindow_vscroll): Doc fix.
5999 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6000 argument, since it makes no sense to pass a live window and for
6001 consistency with window-child.

6033 Move terminal->reference_count++ just before making the frame official
6034 (Bug#9943).

6128 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6129 HAVE_GTK3 (Bug#9869).
6130
6131 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6132 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6133
6134 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6135
6136 * xterm.c: Declare x_handle_net_wm_state to return int.
6137 (handle_one_xevent): Check if we are iconified but don't have
6138 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
6139 (get_current_wm_state): Return non-zero if not hidden,
6140 check for _NET_WM_STATE_HIDDEN (Bug#9893).
6141 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
6142 (x_handle_net_wm_state): Return what get_current_wm_state returns.
6143 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
6144
6145 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6146
6147 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6148 so that this new function doesn't get optimized away by a
6149 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6150
6151 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6152
6153 * frame.h (MOUSE_HL_INFO): Remove excess parens.

6158 * .gdbinit (xprintbytestr): New command.
6159 (xwhichsymbols): Rename from `which'; all callers changed.
6160 (xbytecode): Print the byte-code string as well.
6161
6162 2011-10-29 Kim Storm <storm@cua.dk>
6163
6164 * alloc.c (which_symbols): New function.
6165
6166 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6167
6168 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6169 line. (Bug#9903)
6170
6171 2011-10-29 Glenn Morris <rgm@gnu.org>
6172
6173 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6174 Not clear what it was for, and it causes various bugs. (Bug#9839)
6175
6176 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6177
6178 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6179 possible random value that matches one of those tested as
6180 condition to clear the mouse face.
6181
6182 2011-10-28 Chong Yidong <cyd@gnu.org>
6183
6184 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6185
6186 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6187
6188 * window.c (make_window): Initialize phys_cursor_on_p.
6189
6190 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6191
6192 * lisp.h (struct Lisp_Symbol): Update comments.
6193
6194 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6195
6196 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6197
6198 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6199
6200 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6201 <oslsachem@gmail.com> for helping to debug this.
6202
6203 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6204 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6205 (g_b_init_get_glyph_outline_w): New static variables.
6206 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6207 (GetGlyphOutlineW_Proc): New typedefs.
6208 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6209 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6210 New functions.
6211 (w32font_open_internal, compute_metrics):
6212 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6213 instead of calling the "wide" APIs directly.
6214
6215 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6216
6217 * w32.h (syms_of_w32font): Add prototype.
6218
6219 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6220

6222 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6223 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6224 (Fmove_to_window_line): Doc fix.
6225
6226 2011-10-27 Chong Yidong <cyd@gnu.org>
6227
6228 * process.c (make_process): Set gnutls_state to NULL.
6229
6230 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6231 non-NULL, regardless of GNUTLS_INITSTAGE.
6232 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6233 an error. Set process slots as soon as we allocate them.
6234
6235 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6236
6237 2011-10-27 Chong Yidong <cyd@gnu.org>
6238
6239 * gnutls.c (emacs_gnutls_deinit): New function.
6240 Deallocate credentials structures as well as calling gnutls_deinit.
6241 (Fgnutls_deinit, Fgnutls_boot): Use it.
6242
6243 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6244 (deactivate_process): Call emacs_gnutls_deinit.
6245
6246 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6247
6248 * image.c (x_create_x_image_and_pixmap):
6249 * w32.c (sys_rename, w32_delayed_load):
6250 * w32font.c (fill_in_logfont):
6251 * w32reg.c (x_get_string_resource): Silence compiler warnings.

6256 extracted from Fw32_default_color_map.
6257 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6258
6259 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6260
6261 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6262
6263 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6264
6265 * keyboard.c (test_undefined): New function (bug#9751).

6267
6268 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6269
6270 * sysdep.c (init_sys_modes): Fix the check for the controlling
6271 terminal (Bug#6649).
6272
6273 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6274
6275 * dispextern.h (struct bidi_it): New member next_en_type.
6276
6277 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6278 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6279 current character, check also for next_en_type being WEAK_EN.
6280 (bidi_resolve_weak): Don't enter the expensive loop if the current
6281 position is before next_en_pos. Record the bidi type of the first
6282 non-ET, non-BN character we find, in addition to its position.
6283 (bidi_level_of_next_char): Invalidate next_en_type when
6284 next_en_pos is over-stepped.
6285
6286 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6287
6288 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6289 * editfns.c: Rewrite current-time-zone so that it invokes
6290 the equivalent of (format-time-string "%Z") to get the time zone name.
6291 This fixes a bug when the time zone name contains characters that
6292 need converting from the system time locale to Emacs internal format.
6293 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6294 that patch fixed format-time-string to do the conversion, but
6295 I forgot to fix current-time-zone.
6296 (format_time_string): New function, containing most of
6297 what Fformat_time_string used to contain.
6298 (Fformat_time_string): Rewrite in terms of format_time_string.
6299 This doesn't change this function's behavior.
6300 (current-time-zone): Rewrite to use format_time_string.
6301 This fixes the bug reported by Michael Schierl in
6302 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6303 Jason Rumney's 2007-06-07 change worked around this bug, but
6304 didn't fix it.
6305 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6306
6307 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6308
6309 * xdisp.c (start_display): If the character at POS is displayed
6310 via a display vector, reset IT->current.dpvec_index to zero.
6311 (try_window_reusing_current_matrix): If a line ends in a display
6312 vector or the next line starts in a display vector, continue
6313 redrawing the window even though the character position of
6314 start_row was reached.
6315 (Bug#9771, part 2)
6316
6317 2011-10-18 Chong Yidong <cyd@gnu.org>
6318
6319 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6320 with nobreak-char-display too.
6321
6322 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6323
6324 Fix part 3 of bug#9771.
6325 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6326 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6327 non-neutral characters if the current character is a paragraph
6328 separator (a.k.a. Newline). This avoids running the same
6329 expensive loop twice, once when we consume the preceding newline
6330 and the other time when the line actually needs to be displayed.
6331 Avoid the loop when we see neutrals on the base embedding level
6332 following a character whose directionality is the same as the
6333 paragraph's. This avoids running the expensive loop when a line
6334 ends in a long sequence of neutrals, like control characters.
6335 Add assertion against STRONG_AL type. Slightly rearrange code
6336 that determines the type of a neutral given the first non-neutral
6337 that follows it.
6338 (bidi_level_of_next_char): Set next_en_pos to zero when
6339 invalidating its info.
6340
6341 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6342
6343 * xdisp.c (push_display_prop): Determine whether to record string
6344 or buffer position by IT->string, not by IT->method. Allow
6345 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6346 (move_it_vertically_backward): Don't look for character position
6347 immediately after the newline when in a continuation line.
6348 (Bug#9771, part 1)
6349
6350 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6351
6352 * window.c (coordinates_in_window): Rewrite and delabelize
6353 vertical border check. (Bug#5357) (Bug#9618)
6354
6355 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6356
6357 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6358 errors in XSetWindowBorder (bug#9310).
6359
6360 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6361
6362 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6363 avoid crash when xmalloc overrun checking is enabled.
6364
6365 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6366
6367 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6368 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6369 cursor motion with <left> and <right> arrow keys.
6370
6371 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6372 some callers set that themselves.
6373
6374 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6375
6376 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6377 display string and the previous row comes from the same string and
6378 is empty. (Bug#9739) (Bug#9738)
6379
6380 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6381
6382 * doc.c (get_doc_string): Encode file name (bug#9735).
6383
6384 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6385
6386 * bidi.c (bidi_level_of_next_char):
6387 * xdisp.c (get_visually_first_element): Remove old incorrect
6388 comments regarding the Unicode Line Separator character.
6389
6390 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6391
6392 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6393
6394 * alloc.c (Fgc_status): Do not access beyond zombies array
6395 boundary if nzombies > MAX_ZOMBIES.
6396 * alloc.c (dump_zombies): Add missing format specifier.
6397
6398 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6399
6400 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6401 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6402
6403 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6404 Some packages use them to denote characters with modifiers.
6405
6406 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6407
6408 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6409 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6410 matching a pp-number. Rename parameter var to var1.
6411
6412 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6413
6414 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6415
6416 2011-10-08 Glenn Morris <rgm@gnu.org>
6417
6418 * callint.c (Fcall_interactively): Give a more explicit error for the
6419 'c' case with a non-character input. (Bug#8479)
6420
6421 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6422
6423 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6424 lines.
6425 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6426 lines that are hscrolled on the left.
6427
6428 * dispnew.c (buffer_posn_from_coords): Account for a possible
6429 presence of header-line. (Bug#4426)
6430
6431 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6432
6433 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6434 Don't advertise functionality which we discourage or doesn't work.
6435
6436 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6437
6438 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6439 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6440 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6441 this makes Emacs dump core during garbage collection on rare
6442 occasions. sizeof is obviously inferior to offsetof here, so
6443 stick with offsetof.
6444 (GC_POINTER_ALIGNMENT): New macro.
6445 (mark_memory): Omit 3rd (offset) arg; caller changed.
6446 Don't assume EMACS_INT alignment is the same as pointer alignment.
6447
6448 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6449
6450 * keyboard.c (read_key_sequence_remapped): New var.
6451 (read_key_sequence): Compute remapping in the right buffer.
6452 (command_loop_1): Use read_key_sequence's remapping directly.
6453
6454 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6455
6456 * dired.c (file_name_completion): Don't expand file name.
6457 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6458 before checking file name handler.
6459
6460 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6461 they've been requested explicitly (bug#9591).
6462
6463 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6464
6465 * keymap.c (Fsingle_key_description): Use make_specified_string
6466 instead of build_string to build string from push_key_description.
6467 (Bug#5193)
6468
6469 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6470
6471 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6472 This fixes a Y2038 bug on 64-bit hosts.
6473 * buffer.c (reset_buffer):
6474 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6475 (Fclear_buffer_auto_save_failure):
6476 Use 0, not -1, to represent an unset failure time, since time_t
6477 might not be signed.
6478
6479 Remove dependency on glibc malloc internals.
6480 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6481 Move back here from lisp.h, but with their new implementations.
6482 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6483 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6484 * charset.c (charset_table_init): New static var.
6485 (syms_of_charset): Use it instead of xmalloc. This removes a
6486 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6487 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6488 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6489 Move back to alloc.c.
6490 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6491 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6492
6493 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6494
6495 * nsterm.m (windowDidResize): Call x_set_window_size only when
6496 ns_in_resize is true. Otherwise set pixelwidth/height and
6497 call change_frame_size (Bug#9628).
6498
6499 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6500
6501 Port --enable-checking=all to Fedora 14 x86-64.
6502 * charset.c (syms_of_charset): Also account for glibc malloc's
6503 internal overhead when calculating the initial malloc maximum.
6504
6505 Port --enable-checking=all to Fedora 14 x86.
6506 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6507 Move to lisp.h.
6508 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6509 (overrun_check_realloc, overrun_check_free):
6510 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6511 That way, xmalloc returns a properly-aligned pointer even if
6512 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6513 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6514 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6515 into account when calculating the initial malloc maximum.
6516 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6517 Move here from alloc.c, so that charset.c can use it too.
6518 Properly align; the old code wasn't right for common 32-bit hosts
6519 when configured with --enable-checking=all.
6520 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6521 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6522
6523 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6524
6525 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6526 use EDOM.
6527
6528 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6529
6530 * xdisp.c (compute_display_string_end): If there's no display
6531 string at CHARPOS, return -1.
6532
6533 * bidi.c (bidi_fetch_char): When compute_display_string_end
6534 returns a negative value, treat the character as a normal
6535 character not covered by a display string. (Bug#9624)
6536
6537 2011-09-28 Juanma Barranquero <lekktu@gmail.com>

6541 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6542
6543 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6544 newline, reseat the iterator instead of bidi-iterating there one
6545 character at a time. (Bug#9610)
6546 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6547 TO_CHARPOS if the bidi iterator is at base embedding level.
6548
6549 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>

6581 Default value is now t. Doc fix.
6582
6583 * indent.c (Fvertical_motion): Compute and apply the overshoot
6584 logic when moving up, not only when moving down. Fix the
6585 confusing name and values of the it_overshoot_expected variable;
6586 logic changes accordingly. (Bug#9254) (Bug#9549)
6587
6588 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6589 CHARPOS is covered by a display string which includes newlines.
6590 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS

6600 2011-09-24 Jim Meyering <meyering@redhat.com>
6601
6602 do not ignore write error for any output size
6603 The previous change was incomplete.
6604 While it makes emacs --batch detect the vast majority of stdout
6605 write failures, errors were still ignored whenever the output size is
6606 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6607 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6608 && echo FAIL: ignored write error
6609 FAIL: ignored write error
6610 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6611 && echo FAIL: ignored write error
6612 FAIL: ignored write error
6613 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6614
6615 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6616
6617 * emacs.c (Fkill_emacs): In noninteractive mode exit
6618 non-successfully if a write error occurred on stdout. (Bug#9574)
6619
6620 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6621
6622 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6623 the xassert test.
6624
6625 * dispextern.h (struct it): Update the comment documenting what
6626 can it->OBJECT be.
6627
6628 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6629
6630 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6631 a display string, extend search for cursor position to end of row.
6632 (find_row_edges): If the row ends in a newline from a display
6633 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6634 Handle the case of a display string with multiple newlines.
6635 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6636 non-empty line. Fixes confusing cursor motion with arrow keys at
6637 the beginning of a line that starts with whitespace.
6638

6650
6651 * xdisp.c (display_line): Record maximum and minimum buffer
6652 positions even if no glyphs were produced (e.g., by a zero-width
6653 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6654 buffer positions that will be removed from the glyph row because
6655 they don't fit.
6656 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6657 column is beyond frame width: don't subtract 1 "pixel" when
6658 computing width of the stretch.
6659 (reseat_at_next_visible_line_start): Undo the change made on
6660 2011-09-17 that saved paragraph information and restored it after
6661 the call to `reseat'. (Bug#9545)
6662
6663 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

6669
6670 * search.c (boyer_moore): Take unibyte characters from pattern

6678
6679 Fix minor problem found by static checking.
6680 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6681 initialized, to pacify gcc -Wuninitialized.
6682
6683 * fileio.c: Report proper errno when syscall falls.
6684 (Finsert_file_contents): Save and restore errno,
6685 so that report_file_error outputs the correct diagnostic.
6686 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6687
6688 2011-09-18 Eli Zaretskii <eliz@gnu.org>

6702 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6703 (bidi_find_paragraph_start): Search back for paragraph beginning
6704 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6705 (bidi_move_to_visually_next): Only trigger paragraph-related
6706 computations when the last character is a newline or at EOB, not
6707 just any NEUTRAL_B. (Bug#9470)
6708
6709 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6710 truncated lines if point is covered by a display string. (Bug#9524)
6711
6712 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6713
6714 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6715 (cons_to_x_long): New function.
6716 (lisp_data_to_selection_data): Use it. Correct the test for
6717 short-versus-long data; it was negated. Break out of vector
6718 loop, for efficiency, when a long datum is discovered.
6719
6720 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6721
6722 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6723
6724 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6725
6726 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6727 GCC PR/17406) by declaring this function with external scope.
6728
6729 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6730
6731 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

6733
6734 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6735

6769 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6770
6771 * xselect.c: Use signed conversions more consistently (Bug#9498).
6772 (selection_data_to_lisp_data): Assume incoming selection data are
6773 signed integers, not unsigned. This is to be consistent with
6774 outgoing selection data, which was modified to use signed integers
6775 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6776 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6777 expects long, not unsigned long.

6800 * minibuf.c (Fread_from_minibuffer): Doc fix.
6801
6802 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6803
6804 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6805 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6806
6807 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6808
6809 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6810 value for non-existent files.
6811
6812 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6813
6814 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6815 set its "size" to -1. This will set the modtime_size field of
6816 the corresponding buffer to -1, which is what
6817 verify-visited-file-modtime expects for files that do not exist.
6818 (Bug#9139)
6819
6820 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6821
6822 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6823 here ...
6824 * lisp.h: ... from here. push_key_description is no longer
6825 defined in keyboard.c, so its declaration should not be in
6826 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6827 logically belongs with push_key_description.
6828
6829 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6830
6831 * buffer.h: Include <sys/types.h> instead of <time.h>.

6848 redisplay in small windows.
6849
6850 2011-09-09 Eli Zaretskii <eliz@gnu.org>

6857 Operate on live windows only.
6858
6859 2011-09-08 Juanma Barranquero <lekktu@gmail.com>

6872 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6873
6874 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6875 Without this fix, the command to link temacs failed due to an
6876 undefined symbol __builtin_isnan. This is because
6877 /usr/include/iso/math_c99.h #defines isnan(x) to
6878 __builtin_isnan(x), but the bundled gcc, which identifies itself
6879 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6880 a __builtin_isnan.
6881 * floatfns.c (isnan): #undef, and then #define to a clone of
6882 what's in data.c.
6883 (Fisnan): Always define, since it's always available now.
6884 (syms_of_floatfns): Always define isnan at the Lisp level.
6885
6886 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6887
6888 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6889
6890 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6891
6892 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6893 The previous code assumed that file offsets (off_t values) fit in
6894 EMACS_INT variables, which is not true on typical 32-bit hosts.
6895 The code messed up by falsely reporting buffer overflow in cases
6896 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6897 when "big" contains more than 2**29 bytes, even though this
6898 inserts just one byte and does not overflow the buffer.
6899 (Finsert_file_contents): Store file offsets as off_t
6900 values, not as EMACS_INT values. Check for overflow when
6901 converting between EMACS_INT and off_t. When checking for
6902 buffer overflow or for overlap, take the offsets into account.
6903 Don't use EMACS_INT for small values where int suffices.
6904 When checking for overlap, fix a typo: ZV was used where
6905 ZV_BYTE was intended.
6906 (Fwrite_region): Don't assume off_t fits into 'long'.
6907 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6908
6909 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6910
6911 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6912
6913 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6914
6915 sprintf-related integer and memory overflow issues (Bug#9412).
6916
6917 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6918 (esprintf, exprintf, evxprintf): New functions.
6919 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6920 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6921 (modify_event_symbol): Do not assume that the length of
6922 name_alist_or_stem is safe to alloca and fits in int.
6923 (Fexecute_extended_command): Likewise for function name and binding.
6924 (Frecursion_depth): Wrap around reliably on integer overflow.
6925 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6926 since some callers pass EMACS_INT values.
6927 (Fsingle_key_description): Don't crash if symbol name contains more
6928 than MAX_ALLOCA bytes.
6929 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6930 (get_minibuffer): Arg is now EMACS_INT, not int.
6931 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6932 (esprintf, exprintf, evxprintf): New decls.
6933 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6934
6935 * dbusbind.c (signature_cat): New function.
6936 (xd_signature, Fdbus_register_signal):
6937 Do not overrun buffer; instead, report string overflow.
6938
6939 * dispnew.c (add_window_display_history): Don't overrun buffer.
6940 Truncate instead; this is OK since it's just a log.
6941
6942 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6943 even if the time zone offset is outlandishly large.
6944 Don't mishandle offset == INT_MIN.
6945
6946 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6947 when creating daemon; the previous buffer-overflow check was incorrect.
6948
6949 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6950 which has the guts of the old verror function.
6951
6952 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6953 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6954
6955 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6956 (font_unparse_xlfd): Don't blindly alloca long strings.
6957 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6958 fits in int, when using sprintf. Use single snprintf to count
6959 length of string rather than counting it via multiple sprintfs;
6960 that's simpler and more reliable.
6961 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6962 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6963 sprintf, in case result does not fit in int.
6964
6965 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6966 (fontset_from_font): Print it.
6967
6968 * frame.c (tty_frame_count): Now printmax_t, not int.
6969 (make_terminal_frame, set_term_frame_name): Print it.
6970 (x_report_frame_params): In X, window IDs are unsigned long,
6971 not signed long, so print them as unsigned.
6972 (validate_x_resource_name): Check for implausibly long names,
6973 and don't assume name length fits in 'int'.
6974 (x_get_resource_string): Don't blindly alloca invocation name;
6975 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6976 not fit in int.
6977
6978 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6979 (xg_check_special_colors, xg_set_geometry):
6980 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6981
6982 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6983 Use esprintf, not sprintf, in case result does not fit in int.
6984
6985 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6986 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6987 it as a large positive number.
6988 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6989 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6990
6991 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6992 in case result does not fit in int.
6993
6994 * print.c (float_to_string): Detect width overflow more reliably.
6995 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6996 buffer overrun. Don't assume list length fits in 'int'. Treat
6997 print length of 0 as 0, not as infinity; to be consistent with other
6998 uses of print length in this function. Don't overflow print length
6999 index. Don't assume hash table size fits in 'long', or that
7000 vectorlike size fits in 'unsigned long'.
7001
7002 * process.c (make_process): Use printmax_t, not int, to format
7003 process-name gensyms.
7004
7005 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7006
7007 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7008 to avoid potential buffer overrun.
7009
7010 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7011 if X resource line is longer than 512 bytes.
7012
7013 * xfns.c (x_window): Make sprintf buffer a bit bigger
7014 to avoid potential buffer overrun.
7015
7016 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.

7021
7022 Integer overflow fixes for scrolling, etc.
7023 Without these, Emacs silently mishandles large integers sometimes.
7024 For example, "C-u 4294967297 M-x recenter" was treated as if
7025 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7026
7027 * xdisp.c (try_window_id): Check Emacs fixnum range before
7028 converting to 'int'.
7029
7030 * window.c (window_scroll_line_based, Frecenter):
7031 Check that an Emacs fixnum is in range before assigning it to 'int'.
7032 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7033 values converted from Emacs fixnums.
7034 (Frecenter): Don't wrap around a line count if it is out of 'int'
7035 range; instead, treat it as an extreme value.
7036 (Fset_window_configuration, compare_window_configurations):
7037 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7038
7039 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7040 that can exceed INT_MAX. Check that EMACS_INT value is in range
7041 before assigning it to the (possibly-narrower) index.
7042 (match_limit): Don't assume that a fixnum can fit in 'int'.
7043
7044 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7045 exceed INT_MAX.
7046
7047 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7048 (Fvertical_motion): Don't wrap around LINES values that don't fit
7049 in 'int'. Instead, treat them as extreme values. This is good
7050 enough for windows, which can't have more than INT_MAX lines anyway.
7051
7052 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7053
7054 * Require libxml/parser.h to avoid compilation warning.
7055
7056 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7057
7058 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7059 since this reportedly can destroy thread storage.
7060
7061 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7062
7063 * syntax.c (find_defun_start): Update all cache variables if
7064 exiting early (Bug#9401).
7065
7066 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7067
7068 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7069
7070 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7071 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7072 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7073
7074 * term.c (tty_append_glyph): New function.
7075 (produce_stretch_glyph): Static function and its prototype deleted.
7076
7077 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7078 Add prototypes.
7079
7080 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7081
7082 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7083 when checking :margin (Bug#9390).
7084 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7085 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7086 so that the name doesn't mislead. All uses changed.
7087
7088 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7089
7090 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7091 set_tty_hooks.
7092
7093 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7094
7095 * xdisp.c (move_it_to): Don't bail out early when reaching
7096 position beyond to_charpos, if we are scanning backwards.
7097 (move_it_vertically_backward): When DY == 0, make sure we get to
7098 the first character in the line after the newline.
7099
7100 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7101
7102 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7103 (ccl_driver): Do not generate an out-of-range pointer.
7104 (Fccl_execute_on_string): Remove unnecessary check for
7105 integer overflow, noted by Stefan Monnier in
7106 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7107 Remove a FIXME that didn't need fixing.
7108 Simplify the newly-introduced buffer reallocation code.
7109
7110 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7111
7112 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7113
7114 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7115
7116 Integer and memory overflow issues (Bug#9196).
7117
7118 * doc.c (get_doc_string): Rework so that
7119 get_doc_string_buffer_size is the actual buffer size, rather than
7120 being 1 less than the actual buffer size; this makes xpalloc more
7121 convenient.
7122
7123 * image.c (x_allocate_bitmap_record, cache_image):
7124 * xselect.c (Fx_register_dnd_atom):
7125 Simplify previous changes by using xpalloc.
7126
7127 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7128 since either will do and ptrdiff_t is convenient with xpalloc.
7129
7130 * charset.c (charset_table_size)
7131 (struct charset_sort_data.priority): Now ptrdiff_t.
7132 (charset_compare): Don't overflow if priorities differ greatly.
7133 (Fsort_charsets): Don't assume list length fits in int.
7134 Check for size-calculation overflow when allocating sort data.
7135 (syms_of_charset): Allocate an initial charset table that is
7136 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7137
7138 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7139
7140 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7141 The actual value is always <= INT_MAX, and leaving it unsigned made
7142 overflow checking harder.
7143
7144 * dispextern.h (struct glyph_matrix.rows_allocated)
7145 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7146 with xpalloc. The values are still always <= INT_MAX.
7147
7148 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7149
7150 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7151 (SAFE_NALLOCA): New macro.
7152
7153 * region-cache.c (struct boundary.pos, find_cache_boundary)
7154 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7155 (set_cache_region, invalidate_region_cache)
7156 (revalidate_region_cache, know_region_cache, region_cache_forward)
7157 (region_cache_backward, pp_cache):
7158 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7159 so that ptrdiff_t * can be passed to xpalloc.
7160 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7161 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7162 (pp_cache): Don't assume cache_len fits in int.
7163 * region-cache.h: Adjust extern decls to match.
7164
7165 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7166 EMACS_INT, since either will do, for xpalloc.
7167
7168 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7169 (xnmalloc, xnrealloc, xpalloc): New functions.
7170
7171 * bidi.c (bidi_shelve_header_size): New constant.
7172 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7173 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7174
7175 * bidi.c (bidi_cache_shrink):
7176 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7177 (overlay_strings):
7178 Don't update size of array until after memory allocation succeeds,
7179 because xmalloc/xrealloc may not return.
7180 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7181 now that we have proper integer overflow checking.
7182 (record_overlay_string, overlay_strings): Catch overflows when
7183 calculating size of overlay_str_buf.
7184
7185 * callproc.c (Fcall_process): Check for size overflow when
7186 calculating size of args2.
7187 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7188 Normally we prefer signed values, but sticking with ptrdiff_t would
7189 require adding more-complicated checks.
7190
7191 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7192 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7193 Redo buffer-overflow calculations to avoid integer overflow.
7194 Add a FIXME comment where memory seems to be over-allocated.
7195
7196 * character.c (Fstring): Check for size-calculation overflow.
7197
7198 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7199 unnecessary integer overflow. Check for size overflow.
7200 (encode_coding_object): Don't update size until xmalloc succeeds.
7201
7202 * composite.c (get_composition_id): Check for overflow in glyph
7203 length calculations.
7204
7205 Integer and memory overflow fixes for display code.

7207 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7208 (scrolling_window): Check for overflow in size calculations.
7209 (line_draw_cost, realloc_glyph_pool, add_row_entry):
7210 Don't assume glyph table len fits in int.

7219
7220 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7221 (get_doc_string): Check for size calculation overflow.
7222 Don't update size until allocation succeeds.
7223 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7224 EMACS_INT, where ptrdiff_t will do.
7225 (Fsubstitute_command_keys): Check for string overflow.
7226
7227 * editfns.c (set_time_zone_rule): Don't assume environment length
7228 fits in int.
7229 (message_length): Now ptrdiff_t, not int.
7230 (Fmessage_box): Don't update size until allocation succeeds.
7231 Don't assume message length fits in int.
7232 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7233
7234 * emacs.c (main): Do not reallocate argv, since there is a null at
7235 the end that can be overwritten, and this way there's no need to
7236 worry about size-calculation overflow.
7237 (sort_args): Check for size-calculation overflow.
7238
7239 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7240 alloc succeeds.
7241 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7242
7243 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7244 (x_set_scroll_bar_width, x_figure_window_size):
7245 Check for integer overflow.
7246 (x_set_alpha): Do not assume XINT fits in int.
7247
7248 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7249 This is for the members text_lines, text_cols, total_lines, total_cols,
7250 where the system imposes an 'int' limit.
7251
7252 * fringe.c (Fdefine_fringe_bitmap):
7253 Don't update size until alloc works.
7254
7255 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7256 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7257
7258 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7259 Check for size-calculation overflow.
7260 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7261 do, as we prefer signed integers.
7262 (id_to_widget.max_size, id_to_widget.used)
7263 (xg_store_widget_in_map, xg_remove_widget_from_map)
7264 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7265 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7266 Use and return ptrdiff_t, not int.
7267 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7268 * gtkutil.h: Change prototypes to match the above.
7269
7270 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7271 are duplicate now that they've been promoted to lisp.h.
7272 (x_allocate_bitmap_record, x_alloc_image_color)
7273 (make_image_cache, cache_image, xpm_load):
7274 Don't update size until alloc is done.
7275 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
7276 (x_detect_edges):
7277 Check for size calculation overflow.
7278 (ct_colors_allocated_max): New constant.
7279 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
7280 overflow.

7282 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
7283 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
7284 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7285 Use ptrdiff_t, not int, to count maps.
7286 (read_char_minibuf_menu_prompt): Check for overflow in size
7287 calculations. Don't update size until allocation succeeds.
7288 Redo calculations to avoid overflow.
7289 * keyboard.h: Change prototypes to match the above.

7316
7317 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7318 for command line length. Do not attempt to address one before the
7319 beginning of an array, as that's not portable.
7320
7321 * term.c (max_frame_lines): Remove; unused.
7322 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7323 not int.

7330
7331 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

7334 until alloc done.
7335
7336 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
7337 Don't update size until alloc done.
7338 Redo size calculations to avoid overflow.
7339 Check for size calculation overflow.
7340 (main) [DEBUG]: Fix typo in invoking tparam1.
7341

7348 (Finternal_make_lisp_face, cache_face):
7349 Check for size calculation overflow.
7350 (cache_face): Treat size calculation overflows as if they were
7351 memory exhaustion (the usual treatment), rather than aborting.
7352
7353 * xfns.c (x_encode_text, x_set_name_internal)
7354 (Fx_change_window_property): Use ptrdiff_t, not int, to count

7359 (xg_select): Check for size calculation overflow.
7360 Don't update size until alloc done.
7361
7362 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7363 as sprintf is limited to int lengths.
7364
7365 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7366 (X_LONG_MIN): New macros.
7367 Use them to make the following changes clearer.
7368 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7369 This change doesn't affect the value now, but it may help remind
7370 future maintainers not to raise the value too much later.
7371 (SELECTION_QUANTUM): Remove, replacing with ...
7372 (selection_quantum): ... new function, which avoids overflow.
7373 All uses changed.
7374 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7375 assumption that selection length fits in 'int'.

7378 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7379 (lisp_data_to_selection_data, clean_local_selection_data):
7380 Use ptrdiff_t, not int, to record length of selection.
7381 (x_reply_selection_request, x_get_window_property)
7382 (receive_incremental_selection, x_property_data_to_lisp):
7383 Redo calculations to avoid overflow.
7384 (x_reply_selection_request): When sending hint, ceiling it at
7385 X_LONG_MAX rather than relying on wraparound overflow to send
7386 something.
7387 (x_get_window_property, receive_incremental_selection)
7388 (lisp_data_to_selection_data, x_property_data_to_lisp):
7389 Check for size-calculation overflow.
7390 (x_get_window_property, receive_incremental_selection)
7391 (lisp_data_to_selection_data, Fx_register_dnd_atom):
7392 Don't store size until memory allocation succeeds.
7393 (x_get_window_property): Plug memory leak on memory exhaustion.
7394 Don't double-block input; malloc is safe here. Don't assume 2**34
7395 - 4 fits in unsigned long. Add an xassert to check
7396 XGetWindowProperty overflow. Be more careful about overflow
7397 calculations, and distinguish size from memory overflow better.
7398 (receive_incremental_selection): When tracing, don't assume
7399 unsigned int is less than INT_MAX.
7400 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7401 harmful) conversions of unsigned short to int.
7402 (lisp_data_to_selection_data): Don't assume that integers
7403 in the range -65535 through -1 fit in an X unsigned short.
7404 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7405 result parameters unless successful. Rely on cons_to_unsigned
7406 to report problems with elements; the old code wasn't right anyway.
7407 (x_check_property_data): Check for int overflow; we cannot use
7408 a wider type due to X limits.
7409 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
7410
7411 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
7412
7413 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
7414 (x_term_init): Check for size calculation overflow.
7415 (x_color_cells): Don't store size until memory allocation succeeds.
7416 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
7417 Don't assume alloca size is less than MAX_ALLOCA.
7418 (x_term_init): Don't assume length fits in int (sprintf is limited
7419 to int size).
7420
7421 Use ptrdiff_t for composition IDs.
7422 * character.c (lisp_string_width):
7423 * composite.c (composition_table_size, n_compositions)
7424 (get_composition_id, composition_gstring_from_id):

7441 * lisp.h (hash_lookup, hash_put):
7442 * minibuf.c (Ftest_completion):
7443 Use ptrdiff_t for hash table indexes, not int (which is too
7444 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7445 32-bit --with-wide-int hosts).
7446
7447 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7448 Add a FIXME comment about memory leaks.
7449 (syms_of_charset): Don't assume xmalloc returns.
7450
7451 Don't assume that stated character widths fit in int.
7452 * character.c (Fchar_width, c_string_width, lisp_string_width):
7453 * character.h (CHAR_WIDTH):
7454 * indent.c (MULTIBYTE_BYTES_WIDTH):
7455 Use sanitize_char_width to avoid undefined and/or bad behavior
7456 with outlandish widths.
7457 * character.h (sanitize_tab_width): Rename from sanitize_width,
7458 now that we have two such functions. All uses changed.
7459 (sanitize_char_width): New inline function.
7460
7461 Don't assume that tab-width fits in int.
7462 * character.h (sanitize_width): New inline function.
7463 (SANE_TAB_WIDTH): New macro.

7468
7469 * fileio.c: Integer overflow issues with file modes.
7470 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
7471
7472 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
7473 Remove unreachable code.
7474 (read_hex, load_charset_map_from_file): Check for integer overflow.
7475
7476 * xterm.c: Don't go over XClientMessageEvent limit.
7477 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7478 (x_send_scroll_bar_event): Likewise. Check that the size does not
7479 exceed limits imposed by XClientMessageEvent, as well as the usual
7480 ptrdiff_t and size_t limits.
7481
7482 * keyboard.c: Overflow, signedness and related fixes.
7483 (make_lispy_movement): Use same integer type in forward decl
7484 that is used in the definition.
7485 (read_key_sequence, keyremap_step):
7486 Change bufsize argument back to int, undoing my 2011-03-30 change.
7487 We prefer signed types, and int is wide enough here.
7488 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7489 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7490 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7491 length, not size_t. Use ptrdiff_t for index, not int.
7492 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7493 possibility of integer overflow.
7494
7495 Overflow, signedness and related fixes for images.

7504 * nsmenu.m (update_frame_tool_bar):
7505 * xdisp.c (calc_pixel_width_or_height):
7506 * xfns.c (image_cache_refcount):
7507 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
7508 on typical 64-bit hosts.
7509
7510 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7511 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

7514 when the callers expect that.
7515 (image_ascent): Redo ascent calculation to avoid int overflow.
7516 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7517 (lookup_image): Remove unnecessary tests.
7518 (xbm_image_p): Locals are now of int, not EMACS_INT,
7519 since parse_image_check makes sure they fit into int.
7520 (png_load, gif_load, svg_load_image):
7521 Prefer int to unsigned where either will do.
7522 (tiff_handler): New function, combining the cores of the
7523 old tiff_error_handler and tiff_warning_handler.
7524 This function is rewritten to use vsnprintf and thereby avoid
7525 stack buffer overflows. It uses only the features of vsnprintf
7526 that are common to both POSIX and native Microsoft.
7527 (tiff_error_handler, tiff_warning_handler): Use it.
7528 (tiff_load, gif_load, imagemagick_load_image):
7529 Don't assume :index value fits in 'int'.
7530 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7531 (imagemagick_load_image): Check that crop parameters fit into
7532 the integer types that MagickCropImage accepts. Don't assume
7533 Vimagemagick_render_type has a nonnegative value. Don't assume
7534 size_t fits in 'long'.
7535 (gs_load): Use printmax_t to print the widest integers possible.
7536 Check for integer overflow when computing image height and width.

7539
7540 * xdisp.c (redisplay_window): Don't force window start if point
7541 will be invisible in the resulting window. (Bug#9324)
7542
7543 2011-08-25 Eli Zaretskii <eliz@gnu.org>
7544
7545 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7546 the display spec is of the form `(space ...)'.
7547 (handle_display_spec): Return the value returned by
7548 handle_single_display_spec, not just 1 or zero.
7549 (handle_single_display_spec): If the display spec is of the form
7550 `(space ...)', and specifies display in the text area, return 2
7551 rather than 1.
7552 (try_cursor_movement): Check for the need to scroll more
7553 accurately, and prefer exact match for point under bidi.
7554 Don't advance `row' beyond the last row of the window.
7555
7556 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7557 into disp_prop; all users changed.
7558
7559 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7560 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character

7572 buffers, return left-to-right.
7573 (set_cursor_from_row): Consider candidate row a win if its glyph
7574 represents a newline and point is on that newline. Fixes cursor
7575 positioning on the newline at EOL of R2L text within L2R
7576 paragraph, and vice versa.
7577 (try_cursor_movement): Check continued rows, in addition to
7578 continuation rows. Fixes unwarranted scroll when point enters a
7579 continued line of R2L text within an L2R paragraph, or vice versa.
7580 (cursor_row_p): Consider the case of point being equal to
7581 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7582 from the end of a short line to the beginning of a continued line
7583 of R2L text within L2R paragraph.
7584 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7585 composed characters.
7586

7588 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
7589 members.

7606
7607 * xdisp.c (redisplay_window): When computing centering_position,
7608 account for the height of the header line. (Bug#8874)
7609
7610 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7611 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7612 candidate is selected by the mouse, and that candidate has a
7613 composed character under the mouse.
7614
7615 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7616 coordinates reported by pos-visible-in-window-p for a composed
7617 character in column zero.
7618
7619 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

7624
7625 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7626 consider it a hit if to_charpos is anywhere in the range of the
7627 composed buffer positions.
7628
7629 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7630
7631 * image.c (gif_load): Don't assume that each subimage has the same
7632 dimensions as the base image. Handle disposal method that is
7633 "undefined" by the gif spec (Bug#9335).
7634
7635 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

7643 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7644 from an Org mode buffer to a Speedbar frame.
7645
7646 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7647 a composition, take its buffer position from IT->cmp_it.charpos.
7648 Fixes cursor positioning at the beginning of a line that begins
7649 with a composed character.
7650
7651 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7652
7653 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7654 character bidirectional type, use STRONG_L instead. Fixes crashes
7655 in a buffer produced by `describe-categories'.
7656
7657 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7658 members before the level stack, so they would be saved and
7659 restored when copying iterator state. Fixes incorrect reordering
7660 around TABs covered by display properties.
7661
7662 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7663

7747 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7748 the event loop. Get status from as_status (Bug#7276).
7749
7750 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7751 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7752 the event loop (Bug#7276).

7791 when IT->position is set up wrongly due to some bug.
7792 Set IT->current to match the bidi iterator unconditionally.
7793 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7794 entry. Force push_it to save on the stack the current
7795 buffer/string position, to be restored by pop_it. Fix flags in
7796 the iterator structure wrt the object coming from a display
7797 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7798 properties. (Bug#9284)
7799
7800 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7801
7802 * fontset.c (fontset_get_font_group): Add proper type checks.

7807 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
7808 and LC_VERSION_MIN_MACOSX.
7809 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.

7811
7812 2011-08-08 Eli Zaretskii <eliz@gnu.org>
7813
7814 * xdisp.c (forward_to_next_line_start): Allow to use the
7815 no-display-properties-and-no-overlays under bidi display.
7816 Set disp_pos in the bidi iterator to avoid searches for display
7817 properties and overlays.
7818
7819 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7820
7821 * editfns.c (Fset_time_zone_rule): Document relationship with the

7825 the font entity extracted from the cache (Bug#8109).
7826
7827 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7828
7829 * composite.c (autocmp_chars): Don't reset point. That is done by
7830 restore_point_unwind (Bug#5984).
7831
7832 2011-08-07 Juri Linkov <juri@jurta.org>
7833
7834 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

7838
7839 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7840 display property strides EOL and includes a newline, as in
7841 longlines-mode. (Bug#9254)
7842 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7843 word-wrap under bidirectional display. (Bug#9224)
7844
7845 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7846 is non-zero, even if the data buffer is NULL. Fixes a crash in
7847 vertical-motion with longlines-mode. (Bug#9254)
7848
7849 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7850
7851 * bidi.c <bidi_cache_total_alloc>: Now static.
7852 (bidi_initialize): Initialize bidi_cache_total_alloc.
7853
7854 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7855 cache. (Bug#9221)
7856
7857 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7858 amount allocated this far in `bidi_cache_total_alloc'.
7859 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7860 non-zero, only free the data buffer without restoring the cache
7861 contents. All callers changed.
7862
7863 * dispextern.h (bidi_unshelve_cache): Update prototype.
7864
7865 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7866 (move_it_in_display_line, move_it_to)
7867 (move_it_vertically_backward, move_it_by_lines): Replace the call
7868 to xfree to an equivalent call to bidi_unshelve_cache.
7869 (move_it_in_display_line_to): Fix logic of returning
7870 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7871
7872 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7873
7874 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7875 came from a string character with a `cursor' property. (Bug#9229)
7876
7877 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7878
7879 * Makefile.in (LIB_PTHREAD): New variable.
7880 (LIBES): Add LIB_PTHREAD (Bug#9216).
7881
7882 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
7883 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
7884
7885 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
7886
7887 * regex.c (re_iswctype): Remove some redundant boolean conversions.
7888
7889 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7890
7891 * xterm.c (x_find_topmost_parent): New function.
7892 (x_set_frame_alpha): Find topmost parent window with
7893 x_find_topmost_parent and set the property there also (bug#9181).
7894 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
7895
7896 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
7897
7898 * callproc.c (Fcall_process): Avoid vfork clobbering
7899 the local vars buffer, coding_systems, current_dir.
7900
7901 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
7902
7903 * keymap.c (Fmake_composed_keymap): Move to subr.el.
7904
7905 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
7906
7907 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
7908 so that it is not optimized away.
7909
7910 * xdisp.c (compute_display_string_pos): Remove unused local.
7911
7912 2011-08-02 Eli Zaretskii <eliz@gnu.org>
7913
7914 Fix slow cursor motion and scrolling in large buffers with
7915 selective display, like Org Mode buffers. (Bug#9218)
7916
7917 * dispextern.h (struct bidi_it): New member disp_prop_p.
7918
7919 * xdisp.c: Remove one-slot cache of display string positions.
7920 (compute_display_string_pos): Accept an additional argument
7921 DISP_PROP_P; callers changed. Scan at most 5K characters forward
7922 for a display string or property. If found, set DISP_PROP_P
7923 non-zero.
7924
7925 * bidi.c (bidi_fetch_char): Accept an additional argument
7926 DISP_PROP_P, and pass it to compute_display_string_pos.
7927 Only handle text covered by a display string if DISP_PROP_P is returned
7928 non-zero. All callers of bidi_fetch_char changed.
7929
7930 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
7931
7932 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
7933
7934 2010-12-03 Don March <don@ohspite.net>
7935
7936 * keymap.c (Fdefine_key): Fix non-prefix key error message when
7937 last character M-[char] is translated to ESC [char] (bug#7541).
7938
7939 2011-08-02 Kenichi Handa <handa@m17n.org>
7940
7941 * lisp.h (uniprop_table): Extern it.
7942
7943 * chartab.c (uniprop_table): Make it non-static.
7944
7945 2011-08-01 Eli Zaretskii <eliz@gnu.org>
7946
7947 * xdisp.c (forward_to_next_line_start): Accept additional argument
7948 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7949 on the newline.
7950 (reseat_at_next_visible_line_start): Use the bidi iterator state
7951 returned by forward_to_next_line_start to restore the state of
7952 it->bidi_it after backing up to previous newline. (Bug#9212)
7953
7954 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
7955
7956 * regex.c (re_comp): Protoize.
7957 (re_exec): Fix return type.
7958 (regexec): Fix type of `ret'. (Bug#9203)
7959
7960 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7961
7962 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7963 This is needed if max-image-size is a floating-point number.
7964
7965 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7966
7967 * print.c (print_object): Print empty symbol as ##.
7968
7969 * lread.c (read1): Read ## as empty symbol.
7970
7971 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7972
7973 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7974 setting frame foreground color (Bug#9175).
7975 (x_set_background_color): Likewise.
7976
7977 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7978 contents (Bug#9176).
7979 (EmacsTooltip -init): Remove bezels and add shadows to
7980 tooltip windows.
7981
7982 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7983 or scroll bar (Bug#8470).
7984
7985 * nsfont.m (nsfont_open): Remove assignment to voffset and
7986 unnecessary vars hshink, expand, hd, full_height, min_height.
7987 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7988
7989 * nsterm.h (nsfont_info): Remove voffset field.
7990
7991 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7992
7993 Implement strike-through and overline on NextStep (Bug#8863).
7994
7995 * nsfont.m (nsfont_open): Use underline position provided by font,
7996 instead of hard-coded value of 2.
7997 (nsfont_draw): Call ns_draw_text_decoration instead.
7998
7999 * nsterm.h: Add declaration for ns_draw_text_decoration.
8000
8001 * nsterm.m (ns_draw_text_decoration): New function for drawing
8002 underline, overline, and strike-through.
8003 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8004 ns_draw_text_decoration. Change treatment of cursor drawing to
8005 accommodate underlining, etc.
8006
8007 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8008
8009 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8010 default.
8011
8012 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8013
8014 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8015 Without this fix, if a signal arrives just after memory fills up,
8016 'malloc' might be invoked reentrantly.
8017
8018 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8019 In other words, assume that every image size is allowed, on non-X
8020 hosts. This assumption is probably wrong, but it lets Emacs compile.
8021
8022 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8023
8024 * regex.c (re_iswctype): Convert return values to boolean.
8025
8026 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8027
8028 * xdisp.c (compute_display_string_pos): Don't use cached display
8029 string position if the buffer had its restriction changed.
8030 (Bug#9184)
8031
8032 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8033
8034 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8035
8036 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8037
8038 Integer signedness and overflow and related fixes. (Bug#9079)
8039
8040 * bidi.c: Integer size and overflow fixes.
8041 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8042 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8043 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8044 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8045 (bidi_find_other_level_edge):
8046 Use ptrdiff_t instead of EMACS_INT where either will do.
8047 This works better on 32-bit hosts configured --with-wide-int.
8048 (bidi_cache_ensure_space): Check for size-calculation overflow.
8049 Use % rather than repeated addition, for better worst-case speed.
8050 Don't set bidi_cache_size until after xrealloc returns, because it
8051 might not return.
8052 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8053 (bidi_cache_ensure_space): Also check that the bidi cache size
8054 does not exceed that of the largest Lisp string or buffer. See Eli
8055 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8056
8057 * alloc.c (__malloc_size_t): Remove.
8058 All uses replaced by size_t. See Andreas Schwab's note
8059 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8060
8061 * image.c: Improve checking for integer overflow.
8062 (check_image_size): Assume that f is nonnull, since
8063 it is always nonnull in practice. This is one less thing to
8064 worry about when checking for integer overflow later.
8065 (x_check_image_size): New function, which checks for integer
8066 overflow issues inside X.
8067 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8068 This removes the need for a memory_full check.
8069 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8070 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8071 (xbm_read_bitmap_data): Change locals back to 'int', since
8072 their values must fit in 'int'.
8073 (xpm_load_image, png_load, tiff_load):
8074 Invoke x_create_x_image_and_pixmap earlier,
8075 to avoid much needless work if the image is too large.
8076 (tiff_load): Treat overly large images as if
8077 x_create_x_image_and_pixmap failed, not as malloc failures.
8078 (gs_load): Use x_check_image_size.
8079
8080 * gtkutil.c: Omit integer casts.
8081 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8082 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8083
8084 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8085
8086 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8087 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8088 would wrongly return t on a 64-bit host.
8089
8090 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8091 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8092 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8093 and therefore cause GCC to emit a bogus diagnostic in some cases.
8094
8095 * image.c: Integer signedness and overflow and related fixes.
8096 This is not an exhaustive set of fixes, but it's time to
8097 record what I've got.
8098 (lookup_pixel_color, check_image_size): Remove redundant decls.
8099 (check_image_size): Don't assume that arbitrary EMACS_INT values
8100 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8101 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8102 (tiff_load, imagemagick_load_image):
8103 Check for overflow in size calculations.
8104 (x_create_x_image_and_pixmap): Remove unnecessary test for
8105 xmalloc returning NULL; that can't happen.
8106 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8107 (xpm_color_bucket): Use better integer hashing function.
8108 (xpm_cache_color): Don't possibly over-allocate memory.
8109 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8110 (gif_memory_source):
8111 Use ptrdiff_t, not int or size_t, to record sizes.
8112 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8113 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8114 either works, as we prefer signed integers.
8115 (tiff_read_from_memory, tiff_write_from_memory):
8116 Return tsize_t, not size_t, since that's what the TIFF API wants.
8117 (tiff_read_from_memory): Don't fail simply because the read would
8118 go past EOF; instead, return a short read.
8119 (tiff_load): Omit no-longer-needed casts.
8120 (Fimagemagick_types): Don't assume size fits into 'int'.
8121
8122 Improve hashing quality when configured --with-wide-int.
8123 * fns.c (hash_string): New function, taken from sxhash_string.
8124 Do not discard information about ASCII character case; this
8125 discarding is no longer needed.
8126 (sxhash-string): Use it. Change sig to match it. Caller changed.
8127 * lisp.h: Declare it.
8128 * lread.c (hash_string): Remove, since we now use fns.c's version.
8129 The fns.c version returns a wider integer if --with-wide-int is
8130 specified, so this should help the quality of the hashing a bit.
8131
8132 * emacs.c: Integer overflow minor fix.
8133 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8134 Define only if GNU_LINUX.
8135 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8136
8137 * dispnew.c: Integer signedness and overflow fixes.
8138 Remove unnecessary forward decls, that were a maintenance hassle.
8139 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8140 All uses changed.
8141 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8142 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8143 (prepare_desired_row, line_draw_cost):
8144 Use int, not unsigned, where either works.
8145 (save_current_matrix, restore_current_matrix):
8146 Use ptrdiff_t, not size_t, where either works.
8147 (init_display): Check for overflow more accurately, and without
8148 relying on undefined behavior.
8149
8150 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8151 Remove, replacing with the new symbols in lisp.h. All uses changed.
8152 * fileio.c (make_temp_name):
8153 * filelock.c (lock_file_1, lock_file):
8154 * xdisp.c (message_dolog):
8155 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8156 Use pMd etc. instead.
8157 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8158 replacing the pWIDE etc. symbols removed from editfns.c.
8159
8160 * keyboard.h (num_input_events): Now uintmax_t.
8161 This is (very slightly) less likely to mess up due to wraparound.
8162 All uses changed.
8163
8164 * buffer.c: Integer signedness fixes.
8165 (alloc_buffer_text, enlarge_buffer_text):
8166 Use ptrdiff_t rather than size_t when either will do, as we prefer
8167 signed integers.
8168
8169 * alloc.c: Integer signedness and overflow fixes.
8170 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8171 (__malloc_size_t): Default to size_t, not to int.
8172 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8173 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8174 Prefer ptrdiff_t to size_t when either would do, as we prefer
8175 signed integers.
8176 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8177 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8178 Now const. Initialize with values that are in range even if char
8179 is signed.
8180 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8181 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8182 These functions do the right thing with sizes > 2**32.
8183 (check_depth): Now ptrdiff_t, not int.
8184 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8185 Adjust to new way of storing sizes. Check for size overflow bugs
8186 in rest of code.
8187 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8188 slightly wrong anyway, as it missed one instance of
8189 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8190 (refill_memory_reserve): Omit needless cast to size_t.
8191 (mark_object_loop_halt): Mark as externally visible.
8192
8193 * xselect.c: Integer signedness and overflow fixes.
8194 (Fx_register_dnd_atom, x_handle_dnd_message):
8195 Use ptrdiff_t, not size_t, since we prefer signed.
8196 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8197 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8198 x_dnd_atoms_size and x_dnd_atoms_length.
8199
8200 * doprnt.c: Prefer signed to unsigned when either works.
8201 * eval.c (verror):
8202 * doprnt.c (doprnt):
8203 * lisp.h (doprnt):
8204 * xdisp.c (vmessage):
8205 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8206 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8207 prefer signed arithmetic to avoid comparison confusion.
8208 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8209 but is a bit tricky.
8210
8211 Assume freestanding C89 headers, string.h, stdlib.h.
8212 * data.c, doprnt.c, floatfns.c, print.c:
8213 Include float.h unconditionally.
8214 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8215 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8216 * regex.c: Likewise for stddef.h, string.h.
8217 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8218 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8219 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8220 (STDC_HEADERS): Remove obsolete defines.
8221 * sysdep.c: Include limits.h unconditionally.
8222
8223 Assume support for memcmp, memcpy, memmove, memset.
8224 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8225 * regex.c (memcmp, memcpy):
8226 Remove; we assume C89 now.
8227
8228 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8229 (__malloc_safe_bcopy): Remove; no longer needed.
8230
8231 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8232 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8233 well either way, and we prefer signed to unsigned.
8234
8235 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8236
8237 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8238 closes the connection while we're reading (bug#9182).
8239
8240 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8241
8242 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8243 are specified (Bug#9168).
8244
8245 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8246
8247 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8248 Found by GCC static checking and --with-wide-int on a 32-bit host.
8249
8250 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8251
8252 * xdisp.c (compute_display_string_pos): Fix logic of caching
8253 previous display string position. Initialize cached_prev_pos to
8254 -1. Fixes slow-down at the beginning of a buffer.
8255
8256 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8257
8258 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8259 for attrs[LFACE_FONTSET_INDEX].
8260
8261 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8262
8263 * xml.c (parse_region): Remove unused local
8264 that was recently introduced.
8265
8266 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8267
8268 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8269 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8270
8271 * xdisp.c (move_it_in_display_line_to): Record the best matching
8272 position for TO_CHARPOS while scanning the line, and restore it on
8273 exit if none of the characters scanned was an exact match.
8274 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8275 when exact match is impossible due to invisible text, and the
8276 lines are truncated.
8277
8278 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8279
8280 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8281 for OSX >= 10.7.
8282
8283 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8284
8285 Fix a significant slow-down of cursor motion with C-n, C-p,
8286 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8287 auto-repeat under bidi redisplay in fontified buffers.
8288 * xdisp.c (compute_stop_pos_backwards): New function.
8289 (next_element_from_buffer): Call compute_stop_pos_backwards to
8290 find a suitable prev_stop when we find ourselves before
8291 base_level_stop.
8292 (reseat): Don't look for prev_stop, as that could mean a very long
8293 run.
8294 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8295 <cached_disp_overlay_modiff>: Cache for last found display string
8296 position.
8297 (compute_display_string_pos): Return the cached position if asked
8298 about the same buffer in the same area of character positions, and
8299 the buffer wasn't changed since the time the display string
8300 position was cached.
8301
8302 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8303
8304 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8305 is an integer, which is important for empty lines. (Bug#9149)
8306
8307 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8308
8309 * frame.c (Fmodify_frame_parameters): In tty case, update the
8310 default face if necessary (Bug#4238).
8311
8312 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8313
8314 * editfns.c (Fstring_to_char): No need to explain what a character
8315 is in the docstring (Bug#6576).
8316
8317 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8318
8319 * xml.c (parse_region): Make sure we always return a tree.
8320
8321 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8322
8323 * xml.c (parse_region): If a document contains only comments,
8324 return that, too.
8325
8326 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8327
8328 * xml.c (make_dom): Return comments, too.
8329
8330 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8331
8332 Port to OpenBSD.
8333 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8334 and the surrounding thread.
8335 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8336 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8337 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8338 timer goes off.
8339 * s/openbsd.h (BROKEN_SIGIO): Define.
8340 * unexelf.c (unexec) [__OpenBSD__]:
8341 Don't update the .mdebug section of the Alpha COFF symbol table.
8342
8343 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8344
8345 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8346 (bug#8460).
8347
8348 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8349
8350 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8351 This fixes some race conditions on the permissions of any newly
8352 created file.
8353
8354 * alloc.c (valid_pointer_p): Use pipe, not open.
8355 This fixes some permissions issues when debugging.
8356
8357 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8358 If fchown fails to set both uid and gid, try to set just gid,
8359 as that is sometimes allowed. Adjust the file's mode to eliminate
8360 setuid or setgid bits that are inappropriate if fchown fails.
8361
8362 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8363
8364 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8365 to compare Lisp_Objects.
8366 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8367 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8368 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8369
8370 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8371
8372 * lread.c (read_integer): Unread even EOF character.
8373 (read1): Likewise. Properly record start position of symbol.
8374
8375 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8376 symbol character follows.
8377
8378 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8379
8380 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8381 This works around a problem with the previous change to Fcopy_file.
8382 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8383 and without this change, GCC might complain about discarding
8384 fchown's return value.
8385
8386 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8387
8388 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8389
8390 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8391
8392 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8393
8394 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8395
8396 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8397 it's used from the C level.
8398
8399 * process.c: Use the same condition for POLL_FOR_INPUT in both
8400 keyboard.c and process.c (bug#1858).
8401
8402 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8403
8404 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8405 (Fgnutls_boot): Use it.
8406
8407 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8408
8409 * doc.c (Fsubstitute_command_keys): Revert last change.
8410
8411 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8412
8413 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8414 quotes the next character, and doesn't affect other longer
8415 sequences (bug#8935).
8416
8417 * lread.c (syms_of_lread): Clarify that is isn't only
8418 `eval-buffer' and `eval-defun' that's affected by
8419 `lexical-binding' (bug#8460).
8420
8421 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8422
8423 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8424 bidi redisplay when a line includes both an image and is truncated.
8425
8426 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8427
8428 Fix minor problems found by static checking.
8429 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8430 (elsz): Now a signed constant, not a size_t var. We prefer signed
8431 types to unsigned, to avoid integer comparison confusion. Without
8432 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8433 "cannot optimize loop, the loop counter may overflow", a symptom
8434 of the confusion.
8435 * indent.c (Fvertical_motion): Mark locals as initialized.
8436 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8437
8438 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8439
8440 * search.c (Fre_search_backward): Mention `case-fold-search' in
8441 all the re_search_* functions (bug#8138).
8442
8443 * keyboard.c (Fopen_dribble_file): Document when the file is
8444 closed (bug#8056).
8445
8446 2011-07-14 Eli Zaretskii <eliz@gnu.org>
8447
8448 * bidi.c (bidi_dump_cached_states): Fix format of displaying
8449 bidi_cache_idx.
8450
8451 Support bidi reordering of display and overlay strings.
8452 * xdisp.c (compute_display_string_pos)
8453 (compute_display_string_end): Accept additional argument STRING.
8454 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8455 (reseat_to_string): Initialize bidi_it->string.s and
8456 bidi_it->string.schars.
8457 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8458 NULL (avoids a crash in bidi_paragraph_init).
8459 Initialize itb.string.lstring.
8460 (init_iterator): Call bidi_init_it only of a valid
8461 buffer position was specified. Initialize paragraph_embedding to
8462 L2R.
8463 (reseat_to_string): Initialize the bidi iterator.
8464 (display_string): If we need to ignore text properties of
8465 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8466 original value of -1 will not work with bidi.)
8467 (compute_display_string_pos): First arg is now struct
8468 `text_pos *'; all callers changed. Support display properties on
8469 Lisp strings.
8470 (compute_display_string_end): Support display properties on Lisp
8471 strings.
8472 (init_iterator, reseat_1, reseat_to_string): Initialize the
8473 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8474 when iterating on a string not from display properties).
8475 (compute_display_string_pos, compute_display_string_end):
8476 Fix calculation of the object to scan. Fixes an error when using
8477 arrow keys.
8478 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8479 base_level_stop; instead, set base_level_stop to BEGV.
8480 Fixes crashes in vertical-motion.
8481 (next_element_from_buffer): Improve commentary for when
8482 the iterator is before prev_stop.
8483 (init_iterator): Initialize bidi_p from the default value of
8484 bidi-display-reordering, not from buffer-local value. Use the
8485 buffer-local value only if initializing for buffer iteration.
8486 (handle_invisible_prop): Support invisible properties on strings
8487 that are being bidi-reordered.
8488 (set_iterator_to_next): Support bidi reordering of C strings and
8489 Lisp strings.
8490 (next_element_from_string): Support bidi reordering of Lisp
8491 strings.
8492 (handle_stop_backwards): Support Lisp strings as well.
8493 (display_string): Support display of R2L glyph rows.
8494 Use IT_STRING_CHARPOS when displaying from a Lisp string.
8495 (init_iterator): Don't initialize it->bidi_p for strings
8496 here.
8497 (reseat_to_string): Initialize it->bidi_p for strings here.
8498 (next_element_from_string, next_element_from_c_string)
8499 (next_element_from_buffer): Add xassert's for correspondence
8500 between IT's object being iterated and it->bidi_it.string
8501 structure.
8502 (face_before_or_after_it_pos): Support bidi iteration.
8503 (next_element_from_c_string): Handle the case of the first string
8504 character that is not the first one in the visual order.
8505 (get_visually_first_element): New function, refactored from common
8506 parts of next_element_from_buffer, next_element_from_string, and
8507 next_element_from_c_string.
8508 (tool_bar_lines_needed, redisplay_tool_bar)
8509 (display_menu_bar): Force left-to-right direction. Add a FIXME
8510 comment for making that be controlled by a user option.
8511 (push_it, pop_it): Save and restore the state of the
8512 bidi iterator. Save and restore the bidi_p flag.
8513 (pop_it): Iterate out of display property for string iteration as
8514 well.
8515 (iterate_out_of_display_property): Support iteration over strings.
8516 (handle_single_display_spec): Set up it->bidi_it for iteration
8517 over a display string, and call bidi_init_it.
8518 (handle_single_display_spec, next_overlay_string)
8519 (get_overlay_strings_1, push_display_prop): Set up the bidi
8520 iterator for displaying display or overlay strings.
8521 (forward_to_next_line_start): Don't use the shortcut if
8522 bidi-iterating.
8523 (back_to_previous_visible_line_start): If handle_display_prop
8524 pushed the iterator stack, restore the internal state of the bidi
8525 iterator by calling bidi_pop_it same number of times.
8526 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
8527 and we are bidi-iterating, don't decrement the iterator position;
8528 instead, set the first_elt flag in the bidi iterator, to produce
8529 the same effect.
8530 (reseat_1): Remove redundant setting of string_from_display_prop_p.
8531 (push_display_prop): xassert that we are iterating a buffer.
8532 (push_it, pop_it): Save and restore paragraph_embedding member.
8533 (handle_single_display_spec, next_overlay_string)
8534 (get_overlay_strings_1, reseat_1, reseat_to_string)
8535 (push_display_prop): Set up the `unibyte' member of bidi_it.string
8536 correctly. Don't assume unibyte strings are not bidi-reordered.
8537 (compute_display_string_pos)
8538 (compute_display_string_end): Fix handling the case of C string.
8539 (push_it, pop_it): Save and restore from_disp_prop_p.

8542 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
8543 (pop_it): Call iterate_out_of_display_property only if we are
8544 popping after iteration over a string that came from a display
8545 property. Fix a typo in popping stretch info. Add an assertion
8546 for verifying that the iterator position is in sync with the bidi
8547 iterator.
8548 (handle_single_display_spec, get_overlay_strings_1)
8549 (push_display_prop): Fix initialization of paragraph direction for
8550 string when that of the parent object is not yet determined.
8551 (reseat_1): Call bidi_init_it to resync the bidi
8552 iterator with IT's position. (Bug#7616)
8553 (find_row_edges): If ROW->start.pos gives position
8554 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
8555 (handle_stop, back_to_previous_visible_line_start, reseat_1):
8556 Reset the from_disp_prop_p flag.
8557 (SAVE_IT, RESTORE_IT): New macros.
8558 (pos_visible_p, face_before_or_after_it_pos)
8559 (back_to_previous_visible_line_start)
8560 (move_it_in_display_line_to, move_it_in_display_line)
8561 (move_it_to, move_it_vertically_backward, move_it_by_lines)
8562 (try_scrolling, redisplay_window, display_line): Use them when
8563 saving a temporary copy of the iterator and restoring it back.
8564 (back_to_previous_visible_line_start, reseat_1)
8565 (init_iterator): Empty the bidi cache "stack".
8566 (move_it_in_display_line_to): If iterator ended up at
8567 EOL, but we never saw any buffer positions smaller than
8568 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
8569 motion in bidi-reordered lines.
8570 (move_it_in_display_line_to): Record prev_method and prev_pos
8571 immediately before the call to set_iterator_to_next. Fixes cursor
8572 motion in bidi-reordered lines with stretch glyphs and strings
8573 displayed in margins. (Bug#8133) (Bug#8867)
8574 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
8575 TO_CHARPOS.
8576 (pos_visible_p): Support positions in bidi-reordered lines.
8577 Save and restore bidi cache.
8578
8579 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
8580 (bidi_paragraph_info): Delete unused struct.
8581 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
8582 (bidi_cache_start): New variable.
8583 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
8584 to zero.
8585 (bidi_cache_fetch_state, bidi_cache_search)
8586 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8587 (bidi_cache_find, bidi_peek_at_next_level)
8588 (bidi_level_of_next_char, bidi_find_other_level_edge)
8589 (bidi_move_to_visually_next): Compare cache index with
8590 bidi_cache_start rather than with zero.
8591 (bidi_fetch_char): Accept new argument STRING; all callers
8592 changed. Support iteration over a string. Support strings with
8593 display properties. Support unibyte strings. Fix the type of
8594 `len' according to what STRING_CHAR_AND_LENGTH expects.
8595 (bidi_paragraph_init, bidi_resolve_explicit_1)
8596 (bidi_resolve_explicit, bidi_resolve_weak)
8597 (bidi_level_of_next_char, bidi_move_to_visually_next):
8598 Support iteration over a string.
8599 (bidi_set_sor_type, bidi_resolve_explicit_1)
8600 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
8601 can now be zero (for strings); special values 0 and -1 were
8602 changed to -1 and -2, respectively.
8603 (bidi_char_at_pos): New function.
8604 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
8605 Call it instead of FETCH_MULTIBYTE_CHAR.
8606 (bidi_move_to_visually_next): Abort if charpos or bytepos were not
8607 initialized to valid values.
8608 (bidi_init_it): Don't initialize charpos and bytepos with invalid
8609 values.
8610 (bidi_level_of_next_char): Allow the sentinel "position" to pass

8691
8692 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
8693 The old code sometimes used this field without initializing it.
8694
8695 * alloc.c (gc_sweep): Don't read past end of array.
8696 In theory, the old code could also have corrupted Emacs internals,
8697 though it'd be very unlikely.
8698
8699 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
8700

8798 2011-07-08 Paul Eggert <eggert@cs.ucla.edu>
8799
8800 Use pthread_sigmask, not sigprocmask (Bug#9010).
8801 sigprocmask is portable only for single-threaded applications, and
8802 Emacs can be multi-threaded when it uses GTK.

9000
9001 Random fixes. E.g., (random) never returned negative values.
9002 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9003 subseconds part to the entropy, as that's a bit more random.
9004 Prefer signed to unsigned, since the signedness doesn't matter and
9005 in general we prefer signed. When given a limit, use a
9006 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9007 latter isn't right if USE_2_TAGS_FOR_INTS.
9008 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9009 not 0..VALMASK. Don't discard "excess" bits that random () returns.

9020
9021 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9022 This is more efficient than Ffile_directory_p and avoids a minor race.

9154 * eval.c (struct backtrace): Simplify and port the data structure.
9155 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9156 signed bit field, as this assumption is not portable and it makes

9158 "char debug_on_exit : 1" as this is not portable either; instead,
9159 use the portable "unsigned int debug_on_exit : 1". Remove unused
9160 member evalargs. Remove obsolete comments about cc bombing out.

9243
9244 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling

9347 (read_integer): Radix is now EMACS_INT, not int,
9348 to improve quality of diagnostics for out-of-range radices.
9349 Calculate buffer size correctly for out-of-range radices.
9350 (read1): Check for integer overflow in radices, and in
9351 read-circle numbers.
9352 (read_escape): Avoid int overflow.
9353 (Fload, openp, read_buffer_size, read1)
9354 (substitute_object_recurse, read_vector, read_list, map_obarray):
9355 Use ptrdiff_t, not int, for sizes.

9376
9377 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9378 The following patches are for when GLYPH_DEBUG && !XASSERT.
9379 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9380 * dispnew.c (flush_stdout):
9381 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9382 Mark as externally visible.
9383 * dispnew.c (check_window_matrix_pointers): Now static.
9384 * dispnew.c (window_to_frame_vpos):
9385 * xfns.c (unwind_create_frame):

9387 * scroll.c (CHECK_BOUNDS):
9388 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9389 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9390 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9391 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9392 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9393 Now static.
9394 (debug_method_add): Use va_list and vsprintf rather than relying
9395 on undefined behavior with wrong number of arguments.
9396 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9397 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9398 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9399 since we're not interested in debugging glyphs with old libraries.
9400 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9401 GCC 4.6.0's static checking.
9402
9403 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9404

9423 Use ptrdiff_t, not int, for bitmap indexes.
9424 (x_allocate_bitmap_record): Check for size overflow.
9425 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9426
9427 Use ptrdiff_t, not int, for overlay counts.

9436 (mouse_face_overlay_overlaps, Foverlays_in):
9437 Use ptrdiff_t, not int, for sizes.
9438 (overlays_at, overlays_in): Check for size-calculation overflow.
9439
9440 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9441
9442 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9443 (x_session_initialize): Do not assume string length fits in int.
9444
9445 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9446 This is unlikely, but can occur if DPI is outlandish.
9447
9448 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9449 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9450
9451 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9452 * xrdb.c (magic_file_p, search_magic_path):
9453 Omit last arg SUFFIX; it was always 0. All callers changed.
9454 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9455
9456 * xfont.c (xfont_match): Avoid need for strlen.
9457
9458 * xfns.c: Don't assume strlen fits in int.
9459 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9460
9461 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9462 not unsigned long, as we prefer signed integers. All callers changed.
9463 Detect integer overflow in repeat count.
9464 (message_dolog): Don't assume print length fits in 39 bytes.
9465 (display_mode_element): Don't assume strlen fits in int.
9466
9467 * termcap.c: Don't assume sizes fit in int and never overflow.
9468 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9469 (gobble_line): Check for size-calculation overflow.
9470
9471 * minibuf.c (Fread_buffer):
9472 * lread.c (intern, intern_c_string):
9473 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9474 Don't assume string length fits in int.
9475
9476 * keyboard.c (parse_tool_bar_item):
9477 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9478
9479 * font.c: Don't assume string length fits in int.
9480 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9481 Use ptrdiff_t, not int.
9482 (font_intern_prop): Don't assume string length fits in int.
9483 Don't assume integer property fits in fixnum.
9484 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9485
9486 * filelock.c: Fix some buffer overrun and integer overflow issues.
9487 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9488 Reformulate so as not to need the command string.
9489 Invoke gzip -cd rather than gunzip, as it's more portable.
9490 (lock_info_type, lock_file_1, lock_file):
9491 Don't assume pid_t and time_t fit in unsigned long.
9492 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9493 (current_lock_owner): Prefer signed type for sizes.
9494 Use memcpy, not strncpy, where memcpy is what is really wanted.
9495 Don't assume (via atoi) that time_t and pid_t fit in int.
9496 Check for time_t and/or pid_t out of range, e.g., via a network share.
9497 Don't alloca where an auto var works fine.
9498
9499 * fileio.c: Fix some integer overflow issues.
9500 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9501 Don't assume string length fits in int.
9502 (directory_file_name): Don't assume string length fits in long.
9503 (make_temp_name): Don't assume pid fits in int, or that its print
9504 length is less than 20.
9505
9506 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9507
9508 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9509
9510 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9511
9512 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9513 We prefer signed integers, even for size calculations.
9514
9515 * emacs.c: Don't assume string length fits in 'int'.
9516 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9517 (main): Don't invoke strlen when not needed.
9518
9519 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9520 (XD_DEBUG_MESSAGE): Don't waste a byte.
9521
9522 * callproc.c (getenv_internal_1, getenv_internal)
9523 (Fgetenv_internal):
9524 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9525
9526 * lread.c (invalid_syntax): Omit length argument.
9527 All uses changed. This doesn't fix a bug, but it simplifies the
9528 code away from its former Hollerith-constant appearance, and it's
9529 one less 'int' to worry about when looking at integer-overflow issues.
9530 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9531
9532 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9533 This didn't break anything, but it didn't help either.
9534 It's confusing to put a bogus integer in a place where the actual
9535 value does not matter.
9536 (LIST_END_P): Remove unused macro and its bogus comment.
9537 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9538
9539 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9540 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9541 implementation.
9542 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9543 We prefer signed types, and the value cannot exceed the EMACS_INT
9544 range anyway (because otherwise the length would not be representable).
9545 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9546 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9547 This avoids a GCC warning when WIDE_EMACS_INT.
9548
9549 * indent.c (sane_tab_width): New function.
9550 (current_column, scan_for_column, Findent_to, position_indentation)
9551 (compute_motion): Use it. This is just for clarity.
9552 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9553
9554 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9555
9556 * lisp.h (lint_assume): New macro.
9557 * composite.c (composition_gstring_put_cache):
9558 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9559
9560 * editfns.c, insdel.c:
9561 Omit unnecessary forward decls, to simplify future changes.
9562
9563 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9564
9565 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9566
9567 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9568 Use much-faster test for byte-length change.
9569 Don't assume string byte-length fits in 'int'.
9570 Check that character arg fits in 'int'.
9571 (mapcar1): Declare byte as byte, for clarity.
9572
9573 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9574
9575 * fns.c (concat): Catch string overflow earlier.
9576 Do not rely on integer wraparound.
9577
9578 * dispextern.h (struct it.overlay_strings_charpos)
9579 (struct it.selective): Now EMACS_INT, not int.
9580 * xdisp.c (forward_to_next_line_start)
9581 (back_to_previous_visible_line_start)
9582 (reseat_at_next_visible_line_start, next_element_from_buffer):
9583 Don't arbitrarily truncate the value of 'selective' to int.
9584
9585 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9586
9587 * composite.c: Don't truncate sizes to 'int'.
9588 (composition_gstring_p, composition_reseat_it)
9589 (composition_adjust_point): Use EMACS_INT, not int.
9590 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9591 not EMACS_UINT, for indexes.
9592
9593 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9594
9595 * buffer.c: Include <verify.h>.
9596 (struct sortvec.priority, struct sortstr.priority):
9597 Now EMACS_INT, not int.
9598 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9599 (struct sortstr.size, record_overlay_string)
9600 (struct sortstrlist.size, struct sortlist.used):
9601 Don't truncate size to int.
9602 (record_overlay_string): Check for size-calculation overflow.
9603 (init_buffer_once): Check at compile-time, not run-time.
9604
9605 2011-06-22 Jim Meyering <meyering@redhat.com>
9606
9607 Don't leak an XBM-image-sized buffer
9608 * image.c (xbm_load): Free the image buffer after using it.
9609
9610 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9611
9612 Port to Sun C.
9613 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9614 that Sun C diagnosed.
9615 * fns.c (secure_hash): Fix pointer signedness issue.
9616 * intervals.c (static_offset_intervals): New function.
9617 (offset_intervals): Use it.
9618
9619 2011-06-21 Leo Liu <sdl.web@gmail.com>
9620
9621 * deps.mk (fns.o):
9622 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9623 sha512.h.
9624
9625 * fns.c (secure_hash): Rename from crypto_hash_function and change
9626 the first arg to accept symbols.
9627 (Fsecure_hash): New primitive.
9628 (syms_of_fns): New symbols.
9629
9630 2011-06-20 Deniz Dogan <deniz@dogan.se>
9631
9632 * process.c (Fset_process_buffer): Clarify return value in
9633 docstring.
9634
9635 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9636
9637 * dispnew.c (add_window_display_history): Use BVAR.
9638
9639 * xdisp.c (debug_method_add): Use BVAR.
9640 (check_window_end, dump_glyph_matrix, dump_glyph)
9641 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9642
9643 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9644 Likewise.
9645
9646 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9647 check till after the cache is created in init_frame_faces.
9648
9649 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9650
9651 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9652
9653 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9654
9655 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9656 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9657 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9658
9659 Improve buffer-overflow checking (Bug#8873).
9660 * fileio.c (Finsert_file_contents):
9661 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9662 Remove the old (too-loose) buffer overflow checks.
9663 They weren't needed, since make_gap checks for buffer overflow.
9664 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9665 The old code merely checked for Emacs fixnum overflow, and relied
9666 on undefined (wraparound) behavior. The new code avoids undefined
9667 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9668
9669 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9670 Tune. Don't use wider integers than needed. Don't use alloca.
9671 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9672
9673 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9674
9675 * insdel.c, lisp.h (buffer_overflow): New function.
9676 (insert_from_buffer_1, replace_range, replace_range_2):
9677 * insdel.c (make_gap_larger):
9678 * editfns.c (Finsert_char):
9679 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9680
9681 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9682
9683 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9684
9685 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9686
9687 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9688 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9689
9690 * fileio.c: Don't assume EMACS_INT fits in off_t.
9691 (emacs_lseek): New static function.
9692 (Finsert_file_contents, Fwrite_region): Use it.
9693 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9694
9695 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9696
9697 * fns.c: Don't overflow int when computing a list length.
9698 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9699 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9700 truncation on 64-bit hosts. Check for QUIT every
9701 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9702 faster and is responsive enough.
9703 (Flength): Report an error instead of overflowing an integer.
9704 (Fsafe_length): Return a float if the value is not representable
9705 as a fixnum. This shouldn't happen except in contrived situations.
9706 (Fnthcdr, Fsort): Don't assume list length fits in int.
9707 (Fcopy_sequence): Don't assume vector length fits in int.
9708
9709 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9710 (header_size, word_size): New constants.
9711 (allocate_vectorlike): Don't check size overflow here.
9712 (allocate_vector): Check it here instead, since this is the only
9713 caller of allocate_vectorlike that could cause overflow.
9714 Check that the new vector's length is representable as a fixnum.
9715
9716 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9717 The previous code was bogus. For example, next_almost_prime (32)
9718 returned 39, which is undesirable as it is a multiple of 3; and
9719 next_almost_prime (24) returned 25, which is a multiple of 5 so
9720 why was the code bothering to check for multiples of 7?
9721
9722 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9723
9724 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9725
9726 Variadic C functions now count arguments with ptrdiff_t.
9727 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9728 Back then I didn't know that the Emacs coding style prefers signed int.
9729 Also, in the meantime I found a few more instances where arguments
9730 were being counted with int, which may truncate counts on 64-bit
9731 machines, or EMACS_INT, which may be unnecessarily wide.
9732 * lisp.h (struct Lisp_Subr.function.aMANY)
9733 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9734 Arg counts are now ptrdiff_t, not size_t.
9735 All variadic functions and their callers changed accordingly.
9736 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9737 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9738 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9739 * callint.c (Fcall_interactively): Check arg count for overflow,
9740 to avoid potential buffer overrun. Use signed char, not 'int',
9741 for 'varies' array, so that we needn't bother to check its size
9742 calculation for overflow.
9743 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9744 * eval.c (apply_lambda):
9745 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9746 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9747 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9748
9749 * callint.c (Fcall_interactively): Don't use index var as event count.
9750
9751 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9752 * mem-limits.h (SIZE): Remove; no longer used.
9753
9754 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9755
9756 Remove unnecessary casts.
9757 * xterm.c (x_term_init):
9758 * xfns.c (x_set_border_pixel):
9759 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9760 These aren't needed now that we assume ANSI C.
9761
9762 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9763 It's more likely to cause problems (due to unsigned overflow)
9764 than to cure them.
9765
9766 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9767
9768 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9769
9770 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9771
9772 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9773
9774 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9775
9776 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9777
9778 GLYPH_CODE_FACE returns EMACS_INT, not int.
9779 * dispextern.h (merge_faces):
9780 * xfaces.c (merge_faces):
9781 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9782 Don't assume EMACS_INT fits in int.
9783
9784 * character.h (CHAR_VALID_P): Remove unused parameter.
9785 * fontset.c, lisp.h, xdisp.c: All uses changed.
9786
9787 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9788
9789 * fns.c (concat): Minor tuning based on overflow analysis.
9790 This doesn't fix any bugs. Use int to hold character, instead
9791 of constantly refetching from Emacs object. Use XFASTINT, not
9792 XINT, for value known to be a character. Don't bother comparing
9793 a single byte to 0400, as it's always less.
9794
9795 * floatfns.c (Fexpt):
9796 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9797
9798 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9799 for characters.
9800
9801 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9802
9803 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9804 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9805 incorrectly succeed when S was a string, because 4294967386 was
9806 truncated before it was used.
9807
9808 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9809 Otherwise, an out-of-range integer could cause undefined behavior
9810 on a 64-bit host.
9811
9812 * composite.c: Use int, not EMACS_INT, for characters.
9813 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9814 EMACS_INT, for values that are known to be in character range.
9815 This doesn't fix any bugs but is the usual style inside Emacs and
9816 may generate better code on 32-bit machines.
9817
9818 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9819 This is for reasons similar to the recent CHAR_STRING fix.
9820 * charset.c (Fencode_char): Check that character arg is actually
9821 a character. Pass an int to ENCODE_CHAR.
9822 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9823 wider than 'int', as a compile-time check to prevent future regressions
9824 in this area.
9825
9826 * character.c (char_string): Remove unnecessary casts.
9827
9828 Make sure a 64-bit char is never passed to CHAR_STRING.
9829 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9830 by silently ignoring the top 32 bits, allowing some values
9831 that were far too large to be valid characters.
9832 * character.h: Include <verify.h>.
9833 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9834 arguments are no wider than unsigned, as a compile-time check
9835 to prevent future regressions in this area.
9836 * data.c (Faset):
9837 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9838 (Fsubst_char_in_region):
9839 * fns.c (concat):
9840 * xdisp.c (decode_mode_spec_coding):
9841 Adjust to CHAR_STRING's new requirement.
9842 * editfns.c (Finsert_char, Fsubst_char_in_region):
9843 * fns.c (concat): Check that character args are actually
9844 characters. Without this test, these functions did the wrong
9845 thing with wildly out-of-range values on 64-bit hosts.
9846
9847 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9848 These casts should not be needed on 32-bit hosts, either.
9849 * keyboard.c (read_char):
9850 * lread.c (Fload): Remove casts to unsigned.
9851
9852 * lisp.h (UNSIGNED_CMP): New macro.
9853 This fixes comparison bugs on 64-bit hosts.
9854 (ASCII_CHAR_P): Use it.
9855 * casefiddle.c (casify_object):
9856 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9857 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9858 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9859 * dispextern.h (FACE_FROM_ID):
9860 * keyboard.c (read_char): Use UNSIGNED_CMP.
9861
9862 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9863 not to EMACS_INT, to avoid GCC warning.
9864
9865 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9866
9867 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9868 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9869 isn't needed on 32-bit machines.
9870
9871 * buffer.c (Fgenerate_new_buffer_name):
9872 Use EMACS_INT for count, not int.

9899 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9900 These were 'int' variables that could overflow on 64-bit hosts;
9901 they were never used, so remove them instead of repairing them.

9907
9908 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.

9910 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9911 when a (possibly-narrower) signed value would do just as well.
9912 We prefer using signed arithmetic, to avoid comparison confusion.
9913
9914 * alloc.c: Catch some string size overflows that we were missing.
9915 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9916 for convenience in STRING_BYTES_MAX.
9917 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9918 The definition here is exact; the one in lisp.h was approximate.
9919 (allocate_string_data): Check for string overflow. This catches
9920 some instances we weren't catching before. Also, it catches
9921 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9922 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9923 and ptrdiff_t and EMACS_INT are both 64 bits.
9924
9925 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9926 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9927 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9928
9929 * character.c (string_escape_byte8): Fix nbytes/nchars typo.

10428
10429 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
10430
10431 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
10432 Do not assume that spare memory exists; that assumption is valid
10433 only if SYSTEM_MALLOC.
10434 (LARGE_REQUEST): New macro, so that the issue of large requests
10435 is separated from the issue of spare memory.
10436

10495 display string.
10496 (bidi_paragraph_init, bidi_resolve_explicit_1)
10497 (bidi_level_of_next_char): Call bidi_fetch_char and
10498 bidi_fetch_char_advance instead of FETCH_CHAR and
10499 FETCH_CHAR_ADVANCE.
10500 (bidi_init_it): Initialize new members.
10501 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
10502 definitions.
10503 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
10504 instead of using explicit *_CHAR codes.
10505 (bidi_resolve_explicit, bidi_resolve_weak):
10506 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
10507 bidirectional text is supported only in multibyte buffers.
10508 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
10509 it to initialize the frame_window_p member of struct bidi_it.

10516 were just reseat()'ed to a new position.
10517
10518 * xdisp.c (set_cursor_from_row): Set start and stop points
10519 according to the row's direction when priming the loop that looks
10520 for the glyph on which to display cursor.
10521 (single_display_spec_intangible_p): Function deleted.
10522 (display_prop_intangible_p): Reimplement to call
10523 handle_display_spec instead of single_display_spec_intangible_p.
10524 Accept 3 additional arguments needed by handle_display_spec.
10525 This fixes incorrect cursor motion across display property with complex
10526 values: lists, `(when COND...)' forms, etc.
10527 (single_display_spec_string_p): Support property values that are
10528 lists with the argument STRING its top-level element.
10529 (display_prop_string_p): Fix the condition for processing a
10530 property that is a list to be consistent with handle_display_spec.
10531 (handle_display_spec): New function, refactored from the
10532 last portion of handle_display_prop.
10533 (compute_display_string_pos): Accept additional argument

10535 value of a `display' property is a "replacing spec".
10536 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10537 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
10538 the display property, but just return a value indicating whether

10540 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10541 frame_window_p members of struct bidi_it.
10542 (compute_display_string_pos, compute_display_string_end):

10547
10548 * keyboard.c (adjust_point_for_property): Adjust the call to
10549 display_prop_intangible_p to its new signature.
10550
10551 * dispextern.h (struct bidi_it): New member frame_window_p.
10552 (bidi_init_it): Update prototypes.

10565 All callers changed. (Bug#8762)
10566
10567 * gnutls.c: Use Emacs's memory allocators.
10568 Without this change, the gnutls library would invoke malloc etc.
10569 directly, which causes problems on non-SYNC_INPUT hosts, and which
10570 runs afoul of improving memory_full behavior. (Bug#8761)
10571 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10572 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10573 xfree instead of the default malloc, realloc, free.
10574 (Fgnutls_boot): No need to check for memory allocation failure,
10575 since xmalloc does that for us.
10576

10590 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
10591 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)

10593 * image.c (make_image, search_image_cache, lookup_image)
10594 (xpm_put_color_table_h):
10595 * lisp.h (struct Lisp_Hash_Table):
10596 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
10597 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
10598 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10599 * alloc.c (allocate_vectorlike):
10600 Check for overflow in vector size calculations.
10601 * ccl.c (ccl_driver):
10602 Check for overflow when converting EMACS_INT to int.
10603 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10604 need to be updated by these changes.
10605 * fns.c (make_hash_table, maybe_resize_hash_table):
10606 Check for integer overflow with large hash tables.
10607 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10608 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10609 (SXHASH_REDUCE): New macro.
10610 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10611 Use it instead of discarding useful hash info with large hash values.
10612 (sxhash_float): New function.
10613 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10614 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10615 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10616 Rewrite to use FIXNUM_BITS, as this simplifies things.
10617 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10618 Adjust signatures to match updated version of code.
10619 (consing_since_gc): Now EMACS_INT, since a single hash table can
10620 use more than INT_MAX bytes.

10654 pointer. Remove declaration, not needed.
10655
10656 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10657
10658 Use 'inline', not 'INLINE'.
10659 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
10660 * alloc.c, fontset.c (INLINE): Remove.
10661 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10662 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10663 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10664 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10665 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10666
10667 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10668
10669 Make it possible to run ./temacs.
10670
10671 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10672 syms_of_callproc does the same thing. Remove test for
10673 "initialized", do it in the caller.
10674 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10675
10676 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10677
10678 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10679 (read_minibuf): Use get_minibuffer.
10680 (syms_of_minibuf): Use DEFSYM.
10681 (Qmetadata): New var.
10682 * data.c (Qbuffer): Don't make it static.
10683 (syms_of_data): Use DEFSYM.
10684
10685 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10686
10687 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10688 (CCL_CODE_MIN): New macro.
10689
10690 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10691
10692 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10693
10694 * eval.c (Qdebug): Now static.
10695 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10696 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10697 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10698
10699 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10700
10701 * image.c: Various fixes to ImageMagick code comments.
10702 (Fimagemagick_types): Doc fix.
10703
10704 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10705
10706 Minor fixes prompted by GCC 4.6.0 warnings.
10707
10708 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10709
10710 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10711 (x_clipboard_manager_save_all): Move extern decl to ...
10712 * xterm.h: ... here, so that it can be checked for consistency.
10713
10714 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10715
10716 * xselect.c (x_clipboard_manager_save_frame)
10717 (x_clipboard_manager_save_all): New functions.
10718 (Fx_clipboard_manager_save): Lisp function deleted.
10719
10720 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10721 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10722
10723 * xterm.h: Update prototype.
10724
10725 2011-05-28 William Xu <william.xwl@gmail.com>
10726
10727 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10728 exiting (Bug#8239).
10729
10730 2011-05-28 Jim Meyering <meyering@redhat.com>
10731
10732 Avoid a sign-extension bug in crypto_hash_function.
10733 * fns.c (to_uchar): Define.
10734 (crypto_hash_function): Use it to convert some newly-signed
10735 variables to unsigned, to avoid sign-extension bugs. For example,
10736 without this change, (md5 "truc") would evaluate to
10737 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10738 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10739 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10740
10741 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10742
10743 Integer overflow fixes.
10744
10745 * dbusbind.c: Serial number integer overflow fixes.
10746 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10747 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10748 to hold a serial number that is too large for a fixnum.
10749 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10750 Check for serial numbers out of range. Decode any serial number
10751 that was so large that it became a float. (Bug#8722)
10752
10753 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10754 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10755 Use XFASTINT rather than XUINT when numbers are nonnegative.
10756 (xd_append_arg, Fdbus_method_return_internal):
10757 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10758 arguments, check that Lisp number is nonnegative, rather than
10759 silently wrapping negative numbers around. (Bug#8722)
10760 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10761 (Bug#8722)
10762
10763 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10764
10765 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10766
10767 ccl: Add integer overflow checks.
10768 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10769 (IN_INT_RANGE): New macros.
10770 (ccl_driver): Use them to check for integer overflow when
10771 decoding a CCL program. Many of the new checks are whether XINT (x)
10772 fits in int; it doesn't always, on 64-bit hosts. The new version
10773 doesn't catch all possible integer overflows, but it's an
10774 improvement. (Bug#8719)
10775
10776 * alloc.c (make_event_array): Use XINT, not XUINT.
10777 There's no need for unsigned here.
10778
10779 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10780 This follows up to the 2011-05-06 change that substituted uintptr_t
10781 for EMACS_INT. This case wasn't caught back then.
10782
10783 Rework Fformat to avoid integer overflow issues.
10784 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10785 now (part of C89). Include <verify.h>.
10786 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10787 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10788 (Fformat): Avoid the prepass trying to compute sizes; it was only
10789 approximate and thus did not catch overflow reliably. Instead, walk
10790 through the format just once, formatting and computing sizes as we go,
10791 checking for integer overflow at every step, and allocating a larger
10792 buffer as needed. Keep track separately whether the format is
10793 multibyte. Keep only the most-recently calculated precision, rather
10794 than them all. Record whether each argument has been converted to
10795 string. Use EMACS_INT, not int, for byte and char and arg counts.
10796 Support field widths and precisions larger than INT_MAX. Avoid
10797 sprintf's undefined behavior with conversion specifications such as %#d
10798 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10799 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10800 formatting out-of-range floating point numbers with int
10801 formats. (Bug#8668)
10802
10803 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10804
10805 * data.c: Avoid integer truncation in expressions involving floats.
10806 * data.c: Include <intprops.h>.
10807 (arith_driver): When there's an integer overflow in an expression
10808 involving floating point, convert the integers to floating point
10809 so that the resulting value does not suffer from catastrophic
10810 integer truncation. For example, on a 64-bit host (* 4
10811 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10812 Do not rely on undefined behavior after integer overflow.
10813
10814 merge count_size_as_multibyte, parse_str_to_multibyte
10815 * character.c, character.h (count_size_as_multibyte):
10816 Rename from parse_str_to_multibyte; all uses changed.
10817 Check for integer overflow.
10818 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10819 since it's now a duplicate of the other. This is more of
10820 a character than a buffer op, so better that it's in character.c.
10821 * fns.c, print.c: Adjust to above changes.
10822
10823 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10824
10825 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10826
10827 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10828
10829 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10830 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10831 (x_clipboard_manager_save): Now static.
10832 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10833
10834 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10835 (crypto_hash_function): Now static.
10836 Fix pointer signedness problems. Avoid unnecessary initializations.
10837
10838 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10839
10840 * termhooks.h (Vselection_alist): Make it terminal-local.
10841
10842 * terminal.c (create_terminal): Initialize it.
10843
10844 * xselect.c: Support for clipboard managers.
10845 (Vselection_alist): Move to termhooks.h as terminal-local var.
10846 (LOCAL_SELECTION): New macro.
10847 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10848 (symbol_to_x_atom): Remove gratuitous arg.
10849 (x_handle_selection_request, lisp_data_to_selection_data)
10850 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10851 (x_own_selection, x_get_local_selection, x_convert_selection):
10852 New arg, specifying work frame. Use terminal-local Vselection_alist.
10853 (some_frame_on_display): Delete unused function.
10854 (Fx_own_selection_internal, Fx_get_selection_internal)
10855 (Fx_disown_selection_internal, Fx_selection_owner_p)
10856 (Fx_selection_exists_p): New optional frame arg.
10857 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10858 (x_handle_selection_clear): Don't treat other terminals with the
10859 same keyboard specially. Use the terminal-local Vselection_alist.
10860 (x_clear_frame_selections): Use Frun_hook_with_args.
10861
10862 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10863
10864 * xterm.h: Add support for those atoms.
10865
10866 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10867
10868 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10869 (converted_selections, conversion_fail_tag): New global variables.
10870 (x_selection_request_lisp_error): Free the above.
10871 (x_get_local_selection): Remove unnecessary code.
10872 (x_reply_selection_request): Args changed; handle arbitrary array
10873 of converted selections stored in converted_selections.
10874 Separate the XChangeProperty and SelectionNotify steps.
10875 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10876 (x_convert_selection): New function.
10877 (x_handle_selection_event): Simplify.
10878 (x_get_foreign_selection): Don't ignore incoming requests while
10879 waiting for an answer; this will fail when we implement
10880 SAVE_TARGETS, and seems unnecessary anyway.
10881 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10882 (Vx_sent_selection_functions): Doc fix.
10883
10884 2011-05-26 Leo Liu <sdl.web@gmail.com>
10885
10886 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10887
10888 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10889
10890 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10891
10892 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10893 for fringe update if it has periodic bitmap.
10894 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10895 and fringe_bitmap_periodic_p.
10896
10897 * fringe.c (get_fringe_bitmap_data): New function.
10898 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10899 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10900 row. Mark glyph row for fringe update if periodicity changed.
10901
10902 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10903 for fringe update unless it has periodic bitmap.
10904
10905 2011-05-25 Kenichi Handa <handa@m17n.org>
10906
10907 * xdisp.c (get_next_display_element): Set correct it->face_id for
10908 a static composition.
10909
10910 2011-05-24 Leo Liu <sdl.web@gmail.com>
10911
10912 * deps.mk (fns.o):
10913 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10914
10915 * fns.c (crypto_hash_function, Fsha1): New function.
10916 (Fmd5): Use crypto_hash_function.
10917 (syms_of_fns): Add Ssha1.
10918
10919 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10920
10921 * gnutls.c: Remove unused macros.
10922 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10923 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10924 Remove macros that are defined and never used.
10925 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10926
10927 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10928
10929 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10930 (Fx_get_selection_internal): Minor cleanup.
10931 (Fx_own_selection_internal): Rename arguments for consistency with
10932 select.el.
10933
10934 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10935
10936 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10937
10938 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10939
10940 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10941
10942 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10943
10944 * dispnew.c (scrolling_window): Don't exclude the case that the
10945 last enabled row in the desired matrix touches the bottom boundary.
10946
10947 2011-05-21 Glenn Morris <rgm@gnu.org>
10948
10949 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10950 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10951 and add some more files.
10952
10953 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10954
10955 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10956 report_file_error introduced by the change from 2011-05-07.
10957
10958 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10959
10960 * systime.h (Time): Define only if emacs is defined.
10961 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10962 where the include path doesn't have X11/X.h by default. See
10963 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10964
10965 2011-05-20 Kenichi Handa <handa@m17n.org>
10966
10967 * composite.c (find_automatic_composition): Fix previous change.
10968
10969 2011-05-20 Glenn Morris <rgm@gnu.org>
10970
10971 * lisp.mk: New file, split from Makefile.in.
10972 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10973 (shortlisp): Remove.
10974 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10975
10976 2011-05-19 Glenn Morris <rgm@gnu.org>
10977
10978 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10979 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10980 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10981 (lisp): Set the order to that of loadup.el.
10982 (shortlisp): Make it a copy of $lisp.
10983 (SOME_MACHINE_LISP): Remove.
10984 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10985 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10986
10987 2011-05-18 Kenichi Handa <handa@m17n.org>
10988
10989 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10990 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10991 (find_automatic_composition): Mostly rewrite for efficiency.
10992
10993 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10994
10995 * makefile.w32-in: Update dependencies.
10996
10997 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10998
10999 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11000 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11001
11002 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11003
11004 Fix some integer overflow issues, such as string length overflow.
11005
11006 * insdel.c (count_size_as_multibyte): Check for string overflow.
11007
11008 * character.c (lisp_string_width): Check for string overflow.
11009 Use EMACS_INT, not int, for string indexes and lengths; in
11010 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11011 the resulting string length overflows an EMACS_INT; instead,
11012 report a string overflow if no precision given. When checking for
11013 precision exhaustion, use a check that cannot possibly have
11014 integer overflow. (Bug#8675)
11015 * character.h (lisp_string_width): Adjust to new signature.
11016
11017 * alloc.c (string_overflow): New function.
11018 (Fmake_string): Use it. This doesn't change behavior, but saves
11019 a few bytes and will simplify future changes.
11020 * character.c (string_escape_byte8): Likewise.
11021 * lisp.h (string_overflow): New decl.
11022
11023 Fixups, following up to the user-interface timestamp change.
11024 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11025 for UI timestamps, instead of unsigned long.
11026 * msdos.c (mouse_get_pos): Likewise.
11027 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11028 * w32gui.h (Time): Define by including "systime.h" rather than by
11029 declaring it ourselves. (Bug#8664)
11030
11031 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11032 * image.c (clear_image_cache): Likewise.
11033
11034 * term.c (term_mouse_position): Don't assume time_t wraparound.
11035
11036 Be more systematic about user-interface timestamps.
11037 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11038 and sometimes 'EMACS_UINT', to represent these timestamps.
11039 This change causes it to use 'Time' uniformly, as that's what X uses.
11040 This makes the code easier to follow, and makes it easier to catch
11041 integer overflow bugs such as Bug#8664.
11042 * frame.c (Fmouse_position, Fmouse_pixel_position):
11043 Use Time, not unsigned long, for user-interface timestamps.
11044 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11045 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11046 * keyboard.h (last_event_timestamp): Likewise.
11047 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11048 * menu.h (xmenu_show): Likewise.
11049 * term.c (term_mouse_position): Likewise.
11050 * termhooks.h (struct input_event.timestamp): Likewise.
11051 (struct terminal.mouse_position_hook): Likewise.
11052 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11053 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11054 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11055 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11056 what it was before.
11057 * menu.h, termhooks.h: Include "systime.h", for Time.
11058
11059 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11060 Don't assume that the difference between two unsigned long values
11061 can fit into an integer. At this point, we know button_down_time
11062 <= event->timestamp, so the difference must be nonnegative, so
11063 there's no need to cast the result if double-click-time is
11064 nonnegative, as it should be; check that it's nonnegative, just in
11065 case. This bug is triggered when events are more than 2**31 ms
11066 apart (about 25 days). (Bug#8664)
11067
11068 * xselect.c (last_event_timestamp): Remove duplicate decl.
11069 (x_own_selection): Remove needless cast to unsigned long.
11070
11071 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11072 that always fit in int. Use a sentinel instead of a counter, to
11073 avoid a temp and to allay GCC's concerns about possible int overflow.
11074 * frame.h (struct frame): Use int for menu_bar_items_used
11075 instead of EMACS_INT, since it always fits in int.
11076
11077 * menu.c (grow_menu_items): Check for int overflow.
11078
11079 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11080
11081 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11082 Before, the code was not consistent. These values cannot exceed
11083 2**31 - 1 so there's no need to make them unsigned.
11084 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11085 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11086 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11087 as modifiers.
11088 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11089
11090 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11091 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11092 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11093 presumably because the widths might not match.
11094
11095 * window.c (size_window): Avoid needless test at loop start.
11096
11097 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11098
11099 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11100
11101 2011-05-12 Drew Adams <drew.adams@oracle.com>
11102
11103 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11104
11105 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11106
11107 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11108 `width' to `bar_area_x' and `bar_area_width', respectively.
11109 (x_scroll_run): Take account of fringe background extension.
11110
11111 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11112 Rename local vars `left' and `width' to `bar_area_x' and
11113 `bar_area_width', respectively.
11114 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11115 background extension.
11116
11117 2011-05-10 Jim Meyering <meyering@redhat.com>
11118
11119 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11120
11121 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11122
11123 * image.c (Finit_image_library): Return t for built-in image types,
11124 like pbm and xbm. (Bug#8640)
11125
11126 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11127
11128 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11129
11130 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11131
11132 * w32console.c (Fset_screen_color): Doc fix.
11133 (Fget_screen_color): New function.
11134 (syms_of_ntterm): Defsubr it.
11135
11136 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11137 unlink the temporary file if Fcall_process didn't create it in the
11138 first place.
11139 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11140 child process will be redirected to a file specified with `:file'.
11141 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11142 cue to call_process_cleanup not to close that handle.
11143
11144 2011-05-07 Ben Key <bkey76@gmail.com>
11145
11146 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11147 one of two shell specific rules, either bootstrap-temacs-CMD or
11148 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11149 to the previous implementation of the bootstrap-temacs rule.
11150 The bootstrap-temacs-CMD rule is similar to the previous
11151 implementation of the bootstrap-temacs rule except that it
11152 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11153 variable.
11154
11155 These changes, along with some changes to nt/configure.bat,
11156 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11157 earlier fix to add support for --cflags and --ldflags options
11158 that include quotes so that it works whether make uses cmd or
11159 sh as the shell.
11160
11161 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11162
11163 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11164 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11165 is a constant.
11166 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11167 a string. Handle both cases.
11168 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11169 (Fdbus_register_method): Use Qinvalid_function.
11170
11171 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11172
11173 * makefile.w32-in: Update dependencies.
11174 (LISP_H): Add inttypes.h and stdin.h.
11175 (PROCESS_H): Add unistd.h.
11176
11177 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11178
11179 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11180 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11181
11182 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11183
11184 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11185
11186 * term.c (vfatal): Remove stray call to va_end.
11187 It's not needed and the C Standard doesn't allow it here anyway.
11188
11189 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11190 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11191
11192 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11193 bytes.
11194
11195 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11196
11197 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11198
11199 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11200
11201 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11202
11203 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11204
11205 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11206 * charset.c (Fdefine_charset_internal): Don't initialize
11207 charset.code_space[15]. The value was garbage, on hosts with
11208 32-bit int (Bug#8600).
11209
11210 * lread.c (read_integer): Be more consistent with string-to-number.
11211 Use string_to_number to do the actual conversion; this avoids
11212 rounding errors and fixes some other screwups. Without this fix,
11213 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11214 (digit_to_number): Move earlier, for benefit of read_integer.
11215 Return -1 if the digit is out of range for the base, -2 if it is
11216 not a digit in any supported base. (Bug#8602)
11217
11218 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11219
11220 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11221 to match comment at start of function. This also removes a
11222 GCC warning about overflow in a 32+64-bit port.
11223
11224 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11225
11226 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11227 Reported by Stefan Monnier in
11228 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11229 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11230 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11231
11232 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11233 (EMACS_UINTPTR): Likewise, with uintptr_t.
11234
11235 * lisp.h: Prefer 64-bit EMACS_INT if available.
11236 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11237 on 32-bit hosts that have 64-bit int, so that they can access
11238 large files.
11239 However, temporarily disable this change unless the temporary
11240 symbol WIDE_EMACS_INT is defined.
11241
11242 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11243
11244 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11245 This removes an assumption that EMACS_INT and long are the same
11246 width as pointers. The assumption is true for Emacs porting targets
11247 now, but we want to make other targets possible.
11248 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11249 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11250 In the rest of the code, change types of integers that hold casted
11251 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11252 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11253 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11254 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11255 No need to cast type when ORing.
11256 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11257 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11258 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11259 assume EMACS_INT is the same width as char *.
11260 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11261 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11262 Remove no-longer-needed casts.
11263 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11264 (xg_tool_bar_help_callback, xg_make_tool_item):
11265 Use EMACS_INTPTR to hold an integer
11266 that will be cast to void *; this can avoid a GCC warning
11267 if EMACS_INT is not the same width as void *.
11268 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11269 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11270 (current_message_1, set_message_1):
11271 Use a local to convert to proper width without a cast.
11272 * xmenu.c (dialog_selection_callback): Likewise.
11273
11274 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11275 Also, don't assume VALBITS / RAND_BITS is less than 5,
11276 and don't rely on undefined behavior when shifting a 1 left into
11277 the sign bit.
11278 * lisp.h (get_random): Change signature to match.
11279
11280 * lread.c (hash_string): Use size_t, not int, for hash computation.
11281 Normally we prefer signed values; but hashing is special, because
11282 it's better to use unsigned division on hash table sizes so that
11283 the remainder is nonnegative. Also, size_t is the natural width
11284 for hashing into memory. The previous code used 'int', which doesn't
11285 retain enough info to hash well into very large tables.
11286 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11287
11288 * dbusbind.c: Don't possibly lose pointer info when converting.
11289 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11290 Use XPNTR rather than XHASH, so that the high-order bits of
11291 the pointer aren't lost when converting through void *.
11292
11293 * eval.c (Fautoload): Don't double-shift a pointer.
11294
11295 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11296
11297 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11298
11299 * gnutls.c (DEF_GNUTLS_FN):
11300 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11301
11302 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11303
11304 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11305 marker. (Bug#8610)
11306
11307 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11308
11309 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11310 New version that can reserve upto 2GB of heap space.
11311
11312 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11313
11314 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11315
11316 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11317
11318 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11319 `gnutls_certificate_set_x509_key_file'.
11320
11321 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11322
11323 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11324 Update dependencies.
11325
11326 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11327
11328 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11329 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11330 Remove unused parameter `fildes'.
11331 * process.c (read_process_output, send_process): Don't pass it.
11332
11333 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11334
11335 Fix previous change: the library cache is defined in w32.c.
11336 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11337 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11338
11339 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11340
11341 Implement dynamic loading of GnuTLS on Windows.
11342
11343 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11344 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11345 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11346 Declare.
11347
11348 * gnutls.c (Qgnutls_dll): Define.
11349 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11350 (gnutls_*): Declare function pointers.
11351 (init_gnutls_functions): New function to initialize function pointers.
11352 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11353 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11354 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11355 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11356 (emacs_gnutls_write, emacs_gnutls_read)
11357 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11358 (Fgnutls_available_p): New function.
11359 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11360 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11361 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11362
11363 * image.c: Include w32.h.
11364 (Vimage_type_cache): Delete.
11365 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11366 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11367 (w32_delayed_load): Move to w32.c.
11368
11369 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11370
11371 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11372 (w32_delayed_load): Move from image.c. When loading a library, record
11373 its filename in the :loaded-from property of the library id.
11374 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11375 Initialize and staticpro them.
11376 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11377
11378 * process.c: Include lisp.h before w32.h, not after.
11379 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11380 instead of gnutls_record_check_pending.
11381
11382 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11383
11384 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11385
11386 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11387 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11388 as passed in.
11389
11390 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11391
11392 * xterm.c (x_set_frame_alpha): Do not set property on anything
11393 else than FRAME_X_OUTER_WINDOW (Bug#8608).
11394
11395 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11396
11397 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11398
11399 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11400
11401 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
11402 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

11407 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
11408 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
11409 (Qgnutls_bootprop_callbacks_verify): Make static.
11410
11411 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11412
11413 * callproc.c: Indentation fixup.
11414
11415 * sysdep.c (wait_for_termination_1): Make static.
11416 (wait_for_termination, interruptible_wait_for_termination):
11417 Move after wait_for_termination_1.
11418
11419 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11420
11421 * sysdep.c (interruptible_wait_for_termination): New function
11422 which is like wait_for_termination, but allows keyboard
11423 interruptions.
11424
11425 * callproc.c (Fcall_process): Add (:file "file") as an option for
11426 the STDOUT buffer.
11427 (Fcall_process_region): Ditto.
11428
11429 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11430
11431 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11432 rather than `XVECTOR (FOO)->size'.
11433
11434 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11435 inttypes.h, as a gnulib replacement is used if it not available in
11436 system headers.
11437
11438 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11439
11440 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11441 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11442 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11443
11444 * coding.c (coding_alloc_by_realloc): Error out if destination
11445 will grow beyond MOST_POSITIVE_FIXNUM.
11446 (decode_coding_emacs_mule): Abort if there isn't enough place in
11447 charbuf for the composition carryover bytes. Reserve an extra
11448 space for up to 2 characters produced in a loop.
11449 (decode_coding_iso_2022): Abort if there isn't enough place in
11450 charbuf for the composition carryover bytes.
11451
11452 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11453
11454 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
11455 aborting when %lld or %lll format is passed.
11456 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11457 %llo or %llx format is passed. (Bug#8545)
11458
11459 * window.c (window_scroll_line_based): Use a marker instead of
11460 simple variables to record original value of point. (Bug#7952)
11461
11462 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11463 produced by %s or %c overflows available buffer space. (Bug#8545)
11464
11465 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11466
11467 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11468 (SIZE_MAX): Move defn after all includes, as they might #define it.
11469
11470 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11471
11472 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11473
11474 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11475
11476 * keyboard.c (Qdelayed_warnings_hook): Define.
11477 (command_loop_1): Run `delayed-warnings-hook'
11478 if Vdelayed_warnings_list is non-nil.
11479 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11480 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11481
11482 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11483
11484 * doprnt.c (doprnt): Don't return value smaller than the buffer
11485 size if the message was truncated. (Bug#8545).
11486
11487 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11488
11489 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11490 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11491
11492 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11493
11494 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11495
11496 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11497
11498 * makefile.w32-in: Update dependencies.
11499
11500 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11501
11502 Improve `doprnt' and its usage. (Bug#8545)
11503 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11504 `format_end'. Remove support for %l as a conversion specifier.
11505 Don't use xrealloc. Improve diagnostics when the %l size modifier
11506 is used. Update the commentary.
11507
11508 * eval.c (verror): Simplify calculation of size_t.
11509
11510 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11511 messages.
11512
11513 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11514
11515 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11516 change.
11517
11518 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11519
11520 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11521 This makes this file independent of the recent pseudovector change.
11522
11523 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11524
11525 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11526
11527 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11528 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11529 Remove unused local.
11530 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11531
11532 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11533 GCC 4.6.0 optimizes based on type-based alias analysis.
11534 For example, if b is of type struct buffer * and v of type struct
11535 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11536 != &v->size, and therefore "v->size = 1; b->size = 2; return
11537 v->size;" must therefore return 1. This assumption is incorrect
11538 for Emacs, since it type-puns struct Lisp_Vector * with many other
11539 types. To fix this problem, this patch adds a new type struct
11540 vectorlike_header that documents the constraints on layout of vectors
11541 and pseudovectors, and helps optimizing compilers not get fooled
11542 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11543 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11544 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11545 the size member.
11546 (XSETPVECTYPE): Rewrite in terms of new macro.
11547 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11548 This is a bit clearer, and further avoids the possibility of
11549 undesirable aliasing.
11550 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11551 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11552 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11553 since Lisp_Subr is a special case (no "next" field).
11554 (ASIZE): Now uses header.size rather than size.
11555 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11556 to avoid the hassle of writing XVECTOR (foo)->header.size.
11557 (struct vectorlike_header): New type.
11558 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11559 object, to help avoid aliasing.
11560 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11561 (SUBRP): Likewise, since Lisp_Subr is a special case.
11562 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11563 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11564 (struct Lisp_Hash_Table): Combine first two members into a single
11565 struct vectorlike_header member. All uses of "size" and "next" members
11566 changed to be "header.size" and "header.next".
11567 * buffer.h (struct buffer): Likewise.
11568 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11569 * frame.h (struct frame): Likewise.
11570 * process.h (struct Lisp_Process): Likewise.
11571 * termhooks.h (struct terminal): Likewise.
11572 * window.c (struct save_window_data, struct saved_window): Likewise.
11573 * window.h (struct window): Likewise.
11574 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11575 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11576 * buffer.c (init_buffer_once): Likewise.
11577 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11578 special case.
11579 * process.c (Fformat_network_address): Use local var for size,
11580 for brevity.
11581
11582 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11583
11584 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11585 * data.c (atof): Remove decl; no longer used or needed.
11586 (digit_to_number): Move to lread.c.
11587 (Fstring_to_number): Use new string_to_number function, to be
11588 consistent with how the Lisp reader treats infinities and NaNs.
11589 Do not assume that floating-point numbers represent EMACS_INT
11590 without losing information; this is not true on most 64-bit hosts.
11591 Avoid double-rounding errors, by insisting on integers when
11592 parsing non-base-10 numbers, as the documentation specifies.
11593 * lisp.h (string_to_number): New decl, replacing ...
11594 (isfloat_string): Remove.
11595 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11596 (read1): Do not accept +. and -. as integers; this
11597 appears to have been a coding error. Similarly, do not accept
11598 strings like +-1e0 as floating point numbers. Do not report
11599 overflow for integer overflows unless the base is not 10 which
11600 means we have no simple and reliable way to continue.
11601 Break out the floating-point parsing into a new
11602 function string_to_number, so that Fstring_to_number parses
11603 floating point numbers consistently with the Lisp reader.
11604 (digit_to_number): Move here from data.c. Make it static inline.
11605 (E_CHAR, EXP_INT): Remove, replacing with ...
11606 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11607 (string_to_number): New function, replacing isfloat_string.
11608 This function checks for valid syntax and produces the resulting
11609 Lisp float number too. Rework it so that string-to-number
11610 no longer mishandles examples like "1.0e+". Use strtoumax,
11611 so that overflow for non-base-10 numbers is reported only when
11612 there's no portable and simple way to convert to floating point.
11613
11614 * textprop.c (set_text_properties_1): Rewrite for clarity,
11615 and to avoid GCC warning about integer overflow.
11616
11617 * intervals.h (struct interval): Use EMACS_INT for members
11618 where EMACS_UINT might cause problems. See
11619 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11620 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11621 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11622 All uses changed.
11623 (offset_intervals): Tell GCC not to worry about length overflow
11624 when negating a negative length.
11625
11626 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11627 (overrun_check_free): Likewise.
11628
11629 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11630 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11631 word size.
11632
11633 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11634 (gnutls_make_error): Rename local to avoid shadowing.
11635 (gnutls_emacs_global_deinit): ifdef out; not used.
11636 (Fgnutls_boot): Use const for pointer to readonly storage.
11637 Comment out unused local. Fix pointer signedness problems.
11638
11639 * lread.c (openp): Don't stuff size_t into an 'int'.
11640 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11641 about possible signed overflow.
11642
11643 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11644 (GDK_KEY_g): Don't define if already defined.
11645 (xg_prepare_tooltip): Avoid pointer signedness problem.
11646 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11647
11648 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11649 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11650
11651 * xfns.c (Fx_window_property): Simplify a bit,
11652 to make a bit faster and to avoid GCC 4.6.0 warning.
11653 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11654
11655 * fns.c (internal_equal): Don't assume size_t fits in int.
11656
11657 * alloc.c (compact_small_strings): Tighten assertion a little.
11658
11659 Replace pEd with more-general pI, and fix some printf arg casts.
11660 * lisp.h (pI): New macro, generalizing old pEd macro to other
11661 conversion specifiers. For example, use "...%"pI"d..." rather
11662 than "...%"pEd"...".
11663 (pEd): Remove. All uses replaced with similar uses of pI.
11664 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11665 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11666 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11667 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11668 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11669 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11670 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11671 64-bit hosts.
11672 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11673 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11674 * print.c (safe_debug_print, print_object): Likewise.
11675 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11676 to int.
11677 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11678 avoiding the 0 flag, which is not portable.
11679 * process.c (Fmake_network_process): Use pI to avoid cast.
11680 * region-cache.c (pp_cache): Likewise.
11681 * xdisp.c (decode_mode_spec): Likewise.
11682 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11683 behavior on 64-bit hosts with printf arg.
11684 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11685 (x_stop_queuing_selection_requests): Likewise.
11686 (x_get_window_property): Don't truncate byte count to an 'int'
11687 when tracing.
11688
11689 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11690 here, since it parses constructs like leading '-' and spaces,
11691 which are not wanted; and it overflows with large numbers.
11692 Instead, simply match F[0-9]+, which is what is wanted anyway.
11693
11694 * alloc.c: Remove unportable assumptions about struct layout.
11695 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11696 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11697 (allocate_vectorlike, make_pure_vector): Use the new macros,
11698 plus offsetof, to remove unportable assumptions about struct layout.
11699 These assumptions hold on all porting targets that I know of, but
11700 they are not guaranteed, they're easy to remove, and removing them
11701 makes further changes easier.
11702
11703 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11704 This doesn't fix a bug but makes the code clearer.
11705 (string_overrun_cookie): Now const. Use initializers that
11706 don't formally overflow signed char, to avoid warnings.
11707 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11708 can cause Emacs to crash when string overrun checking is enabled.
11709 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11710 multiple of sizeof (EMACS_INT); it need not be, if
11711 alignof(EMACS_INT) < sizeof (EMACS_INT).
11712 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11713
11714 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
11715
11716 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
11717
11718 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
11719
11720 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
11721 supposed to be handshaking. (Bug#8556)
11722 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11723
11724 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
11725
11726 * lisp.h (Qdebug): List symbol.
11727 * eval.c (Qdebug): Restore global linkage.
11728 * keyboard.c (debug-on-event): New variable.
11729 (handle_user_signal): Break into debugger when debug-on-event
11730 matches the current signal symbol.
11731
11732 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
11733
11734 * alloc.c (check_sblock, check_string_bytes)
11735 (check_string_free_list): Convert to standard C.
11736
11737 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11738
11739 * w32.c (emacs_gnutls_push): Fix typo.
11740
11741 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11742
11743 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11744 "cast to pointer from integer of different size".
11745
11746 Improve doprnt and its use in verror. (Bug#8545)
11747 * doprnt.c (doprnt): Document the set of format control sequences
11748 supported by the function. Use SAFE_ALLOCA instead of always
11749 using `alloca'.
11750
11751 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11752 is one byte too soon. Don't use xrealloc; instead xfree and
11753 xmalloc anew.
11754
11755 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11756
11757 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11758 callbacks stage.
11759
11760 * gnutls.c: Renamed global_initialized to
11761 gnutls_global_initialized. Added internals for the
11762 :verify-hostname-error, :verify-error, and :verify-flags
11763 parameters of `gnutls-boot' and documented those parameters in the
11764 docstring. Start callback support.
11765 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11766 unless a fatal error occurred. Call gnutls_alert_send_appropriate
11767 on error. Return error code.
11768 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
11769 (emacs_gnutls_read): Likewise.
11770 (Fgnutls_boot): Return handshake error code.
11771 (emacs_gnutls_handle_error): New function.
11772 (wsaerror_to_errno): Likewise.
11773
11774 * w32.h (emacs_gnutls_pull): Add prototype.
11775 (emacs_gnutls_push): Likewise.
11776
11777 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
11778 (emacs_gnutls_push): Likewise.
11779
11780 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
11781
11782 * process.c (wait_reading_process_output): Check if GnuTLS
11783 buffered some data internally if no FDs are set for TLS
11784 connections.
11785
11786 * makefile.w32-in (OBJ2): Add gnutls.$(O).
11787 (LIBS): Link to USER_LIBS.
11788 ($(BLD)/gnutls.$(0)): New target.
11789
11790 2011-04-24 Eli Zaretskii <eliz@gnu.org>
11791
11792 * xdisp.c (handle_single_display_spec): Rename the
11793 display_replaced_before_p argument into display_replaced_p, to
11794 make it consistent with the commentary. Fix typos in the
11795 commentary.
11796
11797 * textprop.c (syms_of_textprop): Remove dead code.
11798 (copy_text_properties): Delete obsolete commentary about an
11799 interface that was deleted long ago. Fix typos in the description
11800 of arguments.
11801
11802 * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list

12072 ns_descriptor_to_entity that were caused by using free to

12075 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
12076 --enable-checking=xmallocoverrun). xfree is now used to
12077 deallocate these memory blocks.

12584 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12585 argument, local variables, and return value.
12586
12587 * lisp.h: Update prototypes of emacs_write and emacs_read.
12588
12589 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12590
12591 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12592
12593 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12594
12595 Fix more problems found by GCC 4.6.0's static checks.
12596
12597 * xdisp.c (vmessage): Use a better test for character truncation.
12598
12599 * charset.c (load_charset_map): <, not <=, for optimization,
12600 and to avoid potential problems with integer overflow.
12601 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12602 * casetab.c (set_identity, shuffle): Likewise.
12603 * editfns.c (Fformat): Likewise.
12604 * syntax.c (skip_chars): Likewise.
12605
12606 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12607 This also lets GCC 4.6.0 generate slightly better loop code.
12608
12609 * callint.c (Fcall_interactively): <, not <=, for optimization.
12610 (Fcall_interactively): Count the number of arguments produced,
12611 not the number of arguments given. This is simpler and lets GCC
12612 4.6.0 generate slightly better code.
12613
12614 * ftfont.c: Distingish more carefully between FcChar8 and char.
12615 The previous code passed unsigned char * to a functions like
12616 strlen and xstrcasecmp that expect char *, which does not
12617 conform to the C standard.
12618 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12619 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12620 char * when the C standard requires it.
12621
12622 * keyboard.c (read_char): Remove unused var.
12623
12624 * eval.c: Port to Windows vsnprintf (Bug#8435).
12625 Include <limits.h>.
12626 (SIZE_MAX): Define if the headers do not.
12627 (verror): Do not give up if vsnprintf returns a negative count.
12628 Instead, grow the buffer. This ports to Windows vsnprintf, which
12629 does not conform to C99. Problem reported by Eli Zaretskii.
12630 Also, simplify the allocation scheme, by avoiding the need for
12631 calling realloc, and removing the ALLOCATED variable.
12632
12633 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12634
12635 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12636 But keep the doprint source code for now, as we might revamp it
12637 and use it again (Bug#8435).
12638 * lisp.h (doprnt): Remove.
12639 * Makefile.in (base_obj): Remove doprnt.o.
12640 * deps.mk (doprnt.o): Remove.
12641
12642 error: Print 32- and 64-bit integers portably (Bug#8435).
12643 Without this change, on typical 64-bit hosts error ("...%d...", N)
12644 was used to print both 32- and 64-bit integers N, which relied on
12645 undefined behavior.
12646 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12647 * lisp.h (error, verror): Mark as printf-like functions.
12648 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12649 Report overflow in size calculations when allocating printf buffer.
12650 Do not truncate output string at its first null byte.
12651 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12652 Truncate the output at a character boundary, since vsnprintf does not
12653 do that.
12654 * charset.c (check_iso_charset_parameter): Convert internal
12655 character to string before calling 'error', since %c now has the
12656 printf meaning.
12657 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12658 overflow when computing char to be passed to 'error'. Do not
12659 pass Lisp_Object to 'error'; pass the integer instead.
12660 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12661 formatted with plain %d.
12662
12663 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12664
12665 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12666
12667 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12668
12669 * xterm.c (x_catch_errors): Remove duplicate declaration.
12670
12671 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12672
12673 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12674
12675 2011-04-10 Jim Meyering <meyering@redhat.com>
12676
12677 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12678 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12679 return ssize_t not "int", and use size_t as the buffer length.
12680 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12681 * gnutls.h: Update declarations.
12682 * process.c (read_process_output): Use ssize_t, to match.
12683 (send_process): Likewise.
12684
12685 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12686
12687 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12688
12689 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12690
12691 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12692 Use unsigned char, to match FcChar8 type definition.
12693
12694 * xterm.c (handle_one_xevent):
12695 * xmenu.c (create_and_show_popup_menu):
12696 * xselect.c (x_decline_selection_request)
12697 (x_reply_selection_request): Avoid type-punned deref of X events.
12698
12699 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12700
12701 Fix some uses of `int' instead of EMACS_INT.
12702 * search.c (string_match_1, fast_string_match)
12703 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12704 (scan_buffer, find_next_newline_no_quit)
12705 (find_before_next_newline, search_command, Freplace_match)
12706 (Fmatch_data): Make some `int' variables be EMACS_INT.
12707
12708 * xdisp.c (display_count_lines): 3rd argument and return value now
12709 EMACS_INT. All callers changed.
12710 (pint2hrstr): Last argument is now EMACS_INT.
12711
12712 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12713 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12714 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12715 (decode_coding_utf_16, decode_coding_emacs_mule)
12716 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
12717 (decode_coding_ccl, decode_coding_charset)
12718 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12719 (decode_coding_iso_2022, decode_coding_emacs_mule)
12720 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12721 <char_offset, last_offset>: Declare EMACS_INT.
12722 (encode_coding_utf_8, encode_coding_utf_16)
12723 (encode_coding_emacs_mule, encode_invocation_designation)
12724 (encode_designation_at_bol, encode_coding_iso_2022)
12725 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12726 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12727 Declare EMACS_INT.
12728 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12729 (encode_invocation_designation): Last argument P_NCHARS is now
12730 EMACS_INT.
12731 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12732 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12733
12734 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12735 All users changed.
12736
12737 * ccl.c (Fccl_execute_on_string): Declare some variables
12738 EMACS_INT.
12739
12740 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12741
12742 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12743
12744 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12745
12746 * process.c (Fformat_network_address): Doc fix.
12747
12748 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12749
12750 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12751
12752 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12753
12754 * keyboard.c (read_char): Call Lisp function help-form-show,
12755 instead of using internal_with_output_to_temp_buffer.
12756 (Qhelp_form_show): New var.
12757 (syms_of_keyboard): Use DEFSYM macro.
12758
12759 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12760
12761 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12762
12763 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
12764
12765 * process.c (Flist_processes): Remove to Lisp.
12766 (list_processes_1): Delete.
12767
12768 2011-04-06 Eli Zaretskii <eliz@gnu.org>
12769
12770 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
12771
12772 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12773
12774 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12775
12776 Fix more problems found by GCC 4.6.0's static checks.
12777
12778 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
12779
12780 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12781
12782 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12783
12784 * xdisp.c (vmessage): Mark as a printf-like function.
12785
12786 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
12787
12788 * sound.c (sound_warning): Don't crash if arg contains a printf format.
12789
12790 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
12791 printf-like functions.
12792 (tiff_load): Add casts to remove these marks before passing them
12793 to system-supplied API.
12794
12795 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12796
12797 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12798 This avoids several warnings with gcc -Wstrict-overflow.
12799 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12800 directly, rather than having caller test rule sign. This avoids
12801 some unnecessary tests.
12802 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12803 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12804 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12805
12806 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12807 (xfont_open): Avoid unnecessary tests.
12808
12809 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12810
12811 * composite.h, composite.c (composition_gstring_put_cache):
12812 Use EMACS_INT, not int, for length.
12813
12814 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12815 breaking out part of COMPOSITION_DECODE_RULE.
12816 (COMPOSITION_DECODE_RULE): Use it.
12817 * composite.c (get_composition_id): Remove unused local vars,
12818 by using the new macro.
12819
12820 * textprop.c (set_text_properties_1): Change while to do-while,
12821 since the condition is always true at first.
12822
12823 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12824 (interval_deletion_adjustment): Return unsigned value.
12825 All uses changed.
12826
12827 * process.c (list_processes_1, create_pty, read_process_output):
12828 (exec_sentinel): Remove vars that were set but not used.
12829 (create_pty): Remove unnecessary "volatile"s.
12830 (Fnetwork_interface_info): Avoid possibility of int overflow.
12831 (read_process_output): Do adaptive read buffering even if carryover.
12832 (read_process_output): Simplify nbytes computation if buffered.
12833
12834 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
12835
12836 * syntax.c (scan_words): Remove var that was set but not used.
12837 (update_syntax_table): Use unsigned instead of int.
12838
12839 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
12840 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12841 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12842
12843 * print.c (print_error_message): Avoid int overflow.
12844
12845 * font.c (font_list_entities): Redo for clarity,
12846 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12847
12848 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12849 (font_score): Avoid potential overflow in diff calculation.
12850
12851 * fns.c (substring_both): Remove var that is set but not used.
12852 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12853
12854 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12855
12856 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12857 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12858 can always succeed if overflow has undefined behavior.
12859
12860 * search.c (boyer_moore, wordify): Remove vars set but not used.
12861 (wordify): Omit three unnecessary tests.
12862
12863 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
12864 All callers changed. This avoids the need for an unused var.
12865
12866 * casefiddle.c (casify_region): Remove var that is set but not used.
12867
12868 * dired.c (file_name_completion): Remove var that is set but not used.
12869
12870 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12871
12872 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12873 (Finsert_file_contents): Remove unnecessary code checking fd.
12874
12875 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12876 Check for integer overflow on size calculations.
12877
12878 * buffer.c (Fprevious_overlay_change): Remove var that is set
12879 but not used.
12880
12881 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12882 Remove vars that are set but not used.

12884 (timer_check_2): Mark vars as initialized.
12885
12886 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12887
12888 * image.c (lookup_image): Remove var that is set but not used.
12889 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12890
12891 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12892 that are set but not used.
12893
12894 * xfns.c (make_invisible_cursor): Don't return garbage
12895 if XCreateBitmapFromData fails (Bug#8410).
12896
12897 * xselect.c (x_get_local_selection, x_handle_property_notify):
12898 Remove vars that are set but not used.
12899
12900 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12901 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12902
12903 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12904 Remove var that is set but not used.
12905 (scroll_bar_windows_size): Now size_t, not int.
12906 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12907 Check for overflow.
12908
12909 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12910 (map_tty_color) [!defined MSDOS]: Likewise.
12911
12912 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12913
12914 * coding.c: Remove vars that are set but not used.
12915 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12916 All callers changed.
12917 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12918 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):

12920
12921 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12922 that is set but not used.
12923
12924 * print.c (print_object): Remove var that is set but not used.
12925
12926 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12927 The gnulib version avoids calling malloc in the usual case,
12928 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12929 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12930 * filelock.c (current_lock_owner): Likewise.
12931 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12932 * sysdep.c: Include allocator.h, careadlinkat.h.
12933 (emacs_no_realloc_allocator): New static constant.

12939
12940 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12941 first non-nil return value).
12942
12943 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
12944
12945 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
12946 if not defined (Bug#8403).
12947
12948 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12949
12950 * xdisp.c (display_count_lines): Remove parameter `start',
12951 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

12953 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12954 (fill_stretch_glyph_string): Remove parameters `row' and `area',
12955 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
12956 and thereabouts. All callers changed.
12957 (get_per_char_metric): Remove parameter `f', unused since
12958 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12959
12960 2011-04-02 Jim Meyering <meyering@redhat.com>
12961
12962 do not dereference NULL upon failed strdup
12963 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12964 (ns_get_family): Likewise.
12965
12966 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12967
12968 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

12970 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12971
12972 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12973 later (Bug#8403).

12976
12977 Add lexical binding.
12978

12991
12992 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12993
12994 * keyboard.c (eval_dyn): New fun.
12995 (menu_item_eval_property): Use it.
12996
12997 * image.c (parse_image_spec): Use Ffunctionp.
12998
12999 * fns.c (concat, mapcar1): Accept byte-code-functions.
13000
13001 * eval.c (Fsetq): Handle lexical vars.
13002 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13003 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13004 (FletX, Flet): Obey lexical binding.
13005 (Fcommandp): Handle closures.
13006 (Feval): New `lexical' arg.
13007 (eval_sub): New function extracted from Feval. Use it almost
13008 everywhere where Feval was used. Look up vars in lexical env.
13009 Handle closures.
13010 (Ffunctionp): Move from subr.el.
13011 (Ffuncall): Handle closures.
13012 (apply_lambda): Remove `eval_flags'.
13013 (funcall_lambda): Handle closures and new byte-code-functions.
13014 (Fspecial_variable_p): New function.
13015 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13016 but without exporting it to Lisp.
13017
13018 * doc.c (Fdocumentation, store_function_docstring):
13019 * data.c (Finteractive_form): Handle closures.
13020
13021 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13022 interactive spec.
13023
13024 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13025 New byte-codes.
13026 (exec_byte_code): New function extracted from Fbyte_code to handle new
13027 calling convention for byte-code-functions. Add new byte-codes.
13028
13029 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13030
13031 * alloc.c (Fmake_symbol): Init new `declared_special' field.

13036
13037 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13038
13039 * xdisp.c (SCROLL_LIMIT): New macro.
13040 (try_scrolling): Use it when setting scroll_limit.
13041 Limit scrolling to 100 screen lines.
13042 (redisplay_window): Even when falling back on "recentering",
13043 position point in the window according to scroll-conservatively,
13044 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13045
13046 (try_scrolling): When point is above the window, allow searching
13047 as far as scroll_max, or one screenful, to compute vertical
13048 distance from PT to the scroll margin position. This prevents
13049 try_scrolling from unnecessarily failing when
13050 scroll-conservatively is set to a value slightly larger than the
13051 window height. Clean up the case of PT below the margin at bottom
13052 of window: scroll_max can no longer be INT_MAX. When aggressive
13053 scrolling is in use, don't let point enter the opposite scroll
13054 margin as result of the scroll.
13055 (syms_of_xdisp) <scroll-conservatively>: Document the
13056 threshold of 100 lines for never-recentering scrolling.

13064 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13065 (redisplay_internal): Remove parameter `preserve_echo_area',
13066 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13067
13068 * indent.c (Fvertical_motion):
13069 * window.c (window_scroll_pixel_based, Frecenter):
13070 Don't pass `need_y_p' to `move_it_by_lines'.
13071
13072 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13073
13074 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13075 steal a few bits to be more compact.
13076 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13077 Remove unneeded casts.
13078
13079 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13080
13081 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13082
13083 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13084 binding" message (bug#7967).
13085
13086 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13087
13088 Fix more problems found by GCC 4.6.0's static checks.
13089
13090 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13091 Remove unused local var.
13092
13093 * editfns.c (Fmessage_box): Remove unused local var.
13094
13095 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13096 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13097 Omit unused local vars.
13098 * window.c (shrink_windows): Omit unused local var.
13099 * menu.c (digest_single_submenu): Omit unused local var.
13100 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13101 Omit unused local var.
13102
13103 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13104 Don't assume string length fits in int.
13105 (keyremap_step, read_key_sequence): Use size_t for sizes.
13106 (read_key_sequence): Don't check last_real_key_start redundantly.
13107
13108 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13109 instead of alloca (Bug#8344).
13110
13111 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13112 (Fbacktrace_frame): Don't assume nframes fits in int.
13113
13114 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13115
13116 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13117 concerns.
13118
13119 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13120
13121 * cm.c (calccost): Turn while-do into do-while, for clarity.
13122
13123 * keyboard.c (syms_of_keyboard): Use the same style as later
13124 in this function when indexing through an array. This also
13125 works around GCC bug 48267.
13126
13127 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13128
13129 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

13132 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13133
13134 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13135 This avoids undefined behavior on integer overflow, and is a bit
13136 more convenient anyway since it is compared to a size_t variable.
13137
13138 Variadic C functions now count arguments with size_t, not int.
13139 This avoids an unnecessary limitation on 64-bit machines, which
13140 caused (substring ...) to crash on large vectors (Bug#8344).
13141 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13142 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13143 All variadic functions and their callers changed accordingly.

13149 (funcall_lambda, mark_backtrace): Likewise.
13150 * fns.c (concat): Likewise.
13151 * frame.c (x_set_frame_parameters): Likewise.
13152 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13153 0 if not found, not -1. All callers changed.
13154
13155 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13156 (stack_copy_size): Now size_t, not int.
13157 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

13166 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13167 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13173 * xdisp.c (message_dolog, set_message_1): All callers changed.
13174
13175 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13176
13177 * keyboard.c (safe_run_hook_funcall): New function.
13178 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,

13181 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13182 Vcommand_hook_internal.

13245
13246 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
13247 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
13248
13249 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
13250
13251 * w32.c (read_unc_volume): Use parameter `henum', instead of

13374 This also avoids a gcc -Wstrict-overflow warning.
13375
13376 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13377 leading to a memory leak, possible in functions like
13378 load_charset_map_from_file that can allocate an unbounded number
13379 of objects (Bug#8318).
13380
13381 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13382 that could (at least in theory) be that large.
13383
13384 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13385 This is less likely to overflow, and avoids undefined behavior if
13386 overflow does occur. All callers changed. Use strtoul to scan
13387 for the unsigned long integer.
13388 (pint2hrstr): Simplify and tune code slightly.
13389 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13390
13391 * scroll.c (do_scrolling): Work around GCC bug 48228.
13392 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
13393
13394 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
13395 This also avoids a warning with gcc -Wstrict-overflow.
13396 (validate_x_resource_name): Simplify count usage.
13397 This also avoids a warning with gcc -Wstrict-overflow.
13398
13399 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13400 fail (Bug#8306).
13401
13402 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13403
13404 * process.c (Fmake_network_process): Use socklen_t, not int,
13405 where POSIX says socklen_t is required in portable programs.
13406 This fixes a porting bug on hosts like 64-bit HP-UX, where
13407 socklen_t is wider than int (Bug#8277).
13408 (Fmake_network_process, server_accept_connection):
13409 (wait_reading_process_output, read_process_output):
13410 Likewise.
13411
13412 * process.c: Rename or move locals to avoid shadowing.
13413 (list_processes_1, Fmake_network_process):
13414 (read_process_output_error_handler, exec_sentinel_error_handler):
13415 Rename or move locals.
13416 (Fmake_network_process): Define label "retry_connect" only if needed.
13417 (Fnetwork_interface_info): Fix pointer signedness.
13418 (process_send_signal): Add cast to avoid pointer signedness problem.
13419 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13420 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13421
13422 Make tparam.h and terminfo.c consistent.
13423 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13424 Include tparam.h instead, since it declares them.
13425 * cm.h (PC): Remove extern decl; tparam.h now does this.
13426 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13427 * terminfo.c: Include tparam.h, to check interfaces.
13428 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13429 (tparam): Adjust signature to match interface in tparam.h;
13430 this removes some undefined behavior. Check that outstring and len
13431 are zero, which they always are with Emacs.
13432 * tparam.h (PC, BC, UP): New extern decls.
13433
13434 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13435 (xftfont_open): Rename locals to avoid shadowing.
13436
13437 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13438 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13439 (OTF_TAG_SYM): Omit macro if not needed.
13440 (ftfont_list): Remove unused local.

13442 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
13443 Rename locals to avoid shadowing.
13444
13445 * xfont.c (xfont_list_family): Mark var as initialized.
13446
13447 * xml.c (make_dom): Now static.
13448
13449 * composite.c (composition_compute_stop_pos): Rename local to
13450 avoid shadowing.
13451 (composition_reseat_it): Remove unused locals.
13452 (find_automatic_composition, composition_adjust_point): Likewise.
13453 (composition_update_it): Mark var as initialized.
13454 (find_automatic_composition): Mark vars as initialized,
13455 with a FIXME (Bug#8290).
13456
13457 character.h: Rename locals to avoid shadowing.
13458 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13459 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13460 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13461 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13462 to avoid shadowing.
13463
13464 * textprop.c (property_change_between_p): Remove; unused.
13465
13466 * intervals.c (interval_start_pos): Now static.
13467
13468 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
13469
13470 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
13471 Rename locals to avoid shadowing.
13472
13473 * sound.c (wav_play, au_play, Fplay_sound_internal):
13474 Fix pointer signedness.
13475 (alsa_choose_format): Remove unused local var.
13476 (wav_play): Initialize a variable to 0, to prevent undefined
13477 behavior (Bug#8278).
13478
13479 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13480
13481 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13482
13483 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13484 clobbering (Bug#8298).
13485 * sysdep.c (sys_subshell): Likewise.
13486 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13487
13488 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13489 This should get cleaned up, so that child_setup has the
13490 same signature on all platforms.
13491
13492 * callproc.c (call_process_cleanup): Now static.
13493 (relocate_fd): Rename locals to avoid shadowing.
13494
13495 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13496
13497 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13498 not to be necessary, and produces flickering.
13499
13500 2011-03-20 Glenn Morris <rgm@gnu.org>
13501
13502 * config.in: Remove file.
13503
13504 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13505
13506 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13507 are now in src/globals.h.
13508 (syms_of_minibuf): Remove spurious & from previous change.
13509
13510 2011-03-20 Leo Liu <sdl.web@gmail.com>
13511
13512 * minibuf.c (completing-read-function): New variable.
13513 (completing-read-default): Rename from completing-read.
13514 (completing-read): Call completing-read-function.
13515
13516 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13517
13518 * xfaces.c (Fx_load_color_file):
13519 Read color file from absolute filename (bug#8250).
13520
13521 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13522
13523 * makefile.w32-in: Update dependencies.
13524
13525 2011-03-17 Eli Zaretskii <eliz@gnu.org>
13526
13527 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
13528
13529 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>
13530
13531 Fix more problems found by GCC 4.5.2's static checks.
13532
13533 * process.c (make_serial_process_unwind, send_process_trap):
13534 (sigchld_handler): Now static.
13535
13536 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13537 That way, the code declares only the vars that it needs.
13538 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
13539 * s/cygwin.h (PTY_ITERATION): Likewise.
13540 * s/darwin.h (PTY_ITERATION): Likewise.
13541 * s/gnu-linux.h (PTY_ITERATION): Likewise.
13542
13543 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
13544 * process.c (allocate_pty): Don't declare stb unless it's needed.
13545
13546 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
13547 (CONSTANTLIM): Remove; unused.
13548 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):

13552 to avoid gcc -Wbad-function-cast warning.
13553 Use a different way to cause a compilation error if anyone uses
13554 n rather than nn, a way that does not involve shadowing.
13555 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13556
13557 * deps.mk (unexalpha.o): Remove; unused.
13558
13559 New file unexec.h, the (simple) interface for unexec (Bug#8267).

13562 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
13563 Depend on unexec.h.
13564 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
13565 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
13566 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
13567 Change as necessary to match prototype in unexec.h.
13568
13569 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
13570 shadowing.
13571 (back_comment, skip_chars): Mark vars as initialized.
13572
13573 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

13578
13579 * print.c (Fredirect_debugging_output): Fix pointer signedess.
13580
13581 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
13582 warning when compiling print.c.
13583
13584 * font.c (font_unparse_fcname): Abort in an "impossible" situation
13585 instead of using an uninitialized var.
13586 (font_sort_entities): Mark var as initialized.
13587
13588 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
13589
13590 * font.c (font_unparse_xlfd): Don't mix pointers to variables with
13591 pointers to constants.
13592 (font_parse_fcname): Remove unused vars.
13593 (font_delete_unmatched): Now static.
13594 (font_get_spec): Remove; unused.
13595 (font_style_to_value, font_prop_validate_style, font_unparse_fcname):
13596 (font_update_drivers, Ffont_get_glyphs, font_add_log):
13597 Rename or move locals to avoid shadowing.
13598
13599 * fns.c (require_nesting_list, require_unwind): Now static.
13600 (Ffillarray): Rename locals to avoid shadowing.
13601
13602 * floatfns.c (domain_error2): Define only if needed.
13603 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
13604
13605 * alloc.c (mark_backtrace): Move decl from here ...
13606 * lisp.h: ... to here, so that it can be checked.
13607
13608 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
13609 (Fdefvar): Rewrite so as not to use empty "else".
13610 (lisp_indirect_variable): Name an expression,
13611 to avoid gcc -Wbad-function-cast warning.
13612 (Fdefvar): Rename locals to avoid shadowing.
13613
13614 * callint.c (quotify_arg, quotify_args): Now static.
13615 (Fcall_interactively): Rename locals to avoid shadowing.
13616 Use const pointer when appropriate.
13617
13618 * lisp.h (get_system_name, get_operating_system_release):
13619 Move decls here, to check interfaces.
13620 * process.c (get_operating_system_release): Move decl to lisp.h.
13621 * xrdb.c (get_system_name): Likewise.
13622 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
13623 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
13624 some of which prompt warnings from gcc -Wbad-function-cast.
13625 (Fformat_time_string, Fencode_time, Finsert_char):
13626 (Ftranslate_region_internal, Fformat):
13627 Rename or remove local vars to avoid shadowing.
13628 (Ftranslate_region_internal): Mark var as initialized.
13629
13630 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13631 avoid shadowing.
13632
13633 * lisp.h (eassert): Check that the argument compiles, even if
13634 ENABLE_CHECKING is not defined.
13635
13636 * data.c (Findirect_variable): Name an expression, to avoid
13637 gcc -Wbad-function-cast warning.
13638 (default_value, arithcompare, arith_driver, arith_error): Now static.
13639 (store_symval_forwarding): Rename local to avoid shadowing.
13640 (Fmake_variable_buffer_local, Fmake_local_variable):
13641 Mark variables as initialized.
13642 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
13643
13644 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
13645 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
13646 Rename locals to avoid shadowing.
13647 (mark_stack): Move local variables into the #ifdef region where
13648 they're used.
13649 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
13650 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
13651 needed otherwise.
13652 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13653 (GC_STRING_CHARS): Remove; not used.
13654 (Fmemory_limit): Cast sbrk's returned value to char *.
13655
13656 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
13657 avoids undefined behavior in theory.
13658
13659 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
13660
13661 Use functions, not macros, for up- and down-casing (Bug#8254).
13662 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13663 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13664 to use the following functions instead of these macros.
13665 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13666 EMACS_INT, since callers assume the returned value fits in int.
13667 (upcase1): Likewise, for UPCASE_TABLE.
13668 (uppercasep, lowercasep, upcase): New static inline functions.
13669 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
13670 the race-condition problem in the old DOWNCASE.
13671
13672 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
13673 Rename locals to avoid shadowing.
13674 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
13675 (regex_compile, re_search_2, re_match_2_internal):
13676 Remove unused local vars.
13677 (FREE_VAR): Rewrite so as not to use empty "else",
13678 which gcc can warn about.
13679 (regex_compile, re_match_2_internal): Mark locals as initialized.
13680 (RETALLOC_IF): Define only if needed.
13681 (WORDCHAR_P): Likewise. This one is never needed, but is used
13682 only in a comment talking about a compiler bug, so put inside
13683 the #if 0 of that comment.
13684 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13685 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13686 Remove; unused.
13687
13688 * search.c (boyer_moore): Rename locals to avoid shadowing.
13689 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

13691
13692 * search.c (simple_search): Remove unused var.
13693
13694 * dired.c (compile_pattern): Move decl from here ...
13695 * lisp.h: ... to here, so that it can be checked.
13696 (struct re_registers): New forward decl.
13697
13698 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
13699
13700 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13701 All uses changed.
13702 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13703 Rename locals to avoid shadowing.
13704 (Fvertical_motion): Mark locals as initialized.
13705
13706 * casefiddle.c (casify_object, casify_region): Now static.
13707 (casify_region): Mark local as initialized.
13708
13709 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
13710
13711 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13712 New macros, so that the caller can use some names other than
13713 gcpro1, gcpro2, etc.
13714 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13715 of the new macros.
13716 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13717 argument, for consistency with GCPRO2_VAR, etc: it is now the
13718 prefix of the variable, not the variable itself. All uses
13719 changed.
13720 * dired.c (directory_files_internal, file_name_completion):
13721 Rename locals to avoid shadowing.
13722
13723 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13724 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13725 dired.c's scmp function, had undefined behavior.
13726 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13727 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13728 * buffer.h: ... to here, because these macros use current_buffer,
13729 and the new implementation with inline functions needs to have
13730 current_buffer in scope now, rather than later when the macros
13731 are used.
13732 (downcase, upcase1): New static inline functions.
13733 (DOWNCASE, UPCASE1): Reimplement using these functions.
13734 This avoids undefined behavior in expressions like
13735 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13736 from race conditions in accessing the global variables
13737 case_temp1 and case_temp2.
13738 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13739 * lisp.h (case_temp1, case_temp2): Remove their decls.
13740 * character.h (ASCII_CHAR_P): Move from here ...
13741 * lisp.h: ... to here, so that the inline functions mentioned
13742 above can use them.
13743
13744 * dired.c (directory_files_internal_unwind): Now static.
13745
13746 * fileio.c (file_name_as_directory, directory_file_name):
13747 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13748 Now static.
13749 (file_name_as_directory): Use const pointers when appropriate.
13750 (Fexpand_file_name): Likewise. In particular, newdir might
13751 point at constant storage, so make it a const pointer.
13752 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13753 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13754 signedness issues.
13755 (Fset_file_times, Finsert_file_contents, auto_save_error):
13756 Rename locals to avoid shadowing.
13757
13758 * minibuf.c (choose_minibuf_frame_1): Now static.
13759 (Ftry_completion, Fall_completions): Rename or remove locals
13760 to avoid shadowing.
13761
13762 * marker.c (bytepos_to_charpos): Remove; unused.
13763
13764 * lisp.h (verify_bytepos, count_markers): New decls,
13765 so that gcc does not warn that these functions aren't declared.
13766
13767 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13768 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13769 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13770 (copy_text): Remove unused local var.
13771
13772 * filelock.c (within_one_second): Now static.
13773 (lock_file_1): Rename local to avoid shadowing.
13774
13775 * buffer.c (fix_overlays_before): Mark locals as initialized.
13776 (fix_start_end_in_overlays): Likewise. This function should be
13777 simplified by using pointers-to-pointers, but that's a different
