1 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
4 Also, don't assume VALBITS / RAND_BITS is less than 5,
5 and don't rely on undefined behavior when shifting a 1 left into
7 * lisp.h (get_random): Change signature to match.
9 * lread.c (hash_string): Use size_t, not int, for hash computation.
10 Normally we prefer signed values; but hashing is special, because
11 it's better to use unsigned division on hash table sizes so that
12 the remainder is nonnegative. Also, size_t is the natural width
13 for hashing into memory. The previous code used 'int', which doesn't
14 retain enough info to hash well into very large tables.
15 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
17 * dbusbind.c: Don't possibly lose pointer info when converting.
18 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19 Use XPNTR rather than XHASH, so that the high-order bits of
20 the pointer aren't lost when converting through void *.
22 * eval.c (Fautoload): Don't double-shift a pointer.
24 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
26 2011-04-28 Eli Zaretskii <eliz@gnu.org>
28 * doprnt.c (doprnt): Don't return value smaller than the buffer
29 size if the message was truncated. (Bug#8545).
31 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
33 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
34 (Fx_window_property): #if-0 the whole functions, not just the bodies.
36 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
38 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
40 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
42 * makefile.w32-in: Update dependencies.
44 2011-04-27 Eli Zaretskii <eliz@gnu.org>
46 Improve `doprnt' and its usage. (Bug#8545)
47 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
48 `format_end'. Remove support for %l as a conversion specifier.
49 Don't use xrealloc. Improve diagnostics when the %l size modifier
50 is used. Update the commentary.
52 * eval.c (verror): Simplify calculation of size_t.
54 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
57 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
59 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
62 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
64 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
65 This makes this file independent of the recent pseudovector change.
67 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
69 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
71 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
72 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
74 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
76 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
77 GCC 4.6.0 optimizes based on type-based alias analysis. For
78 example, if b is of type struct buffer * and v of type struct
79 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
80 != &v->size, and therefore "v->size = 1; b->size = 2; return
81 v->size;" must therefore return 1. This assumption is incorrect
82 for Emacs, since it type-puns struct Lisp_Vector * with many other
83 types. To fix this problem, this patch adds a new type struct
84 vectorlike_header that documents the constraints on layout of vectors
85 and pseudovectors, and helps optimizing compilers not get fooled
86 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
87 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
88 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
90 (XSETPVECTYPE): Rewrite in terms of new macro.
91 (XSETPVECTYPESIZE): New macro, specifying both type and size.
92 This is a bit clearer, and further avoids the possibility of
94 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
95 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
96 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
97 since Lisp_Subr is a special case (no "next" field).
98 (ASIZE): Now uses header.size rather than size. All
99 previous uses of XVECTOR (foo)->size replaced to use this macro,
100 to avoid the hassle of writing XVECTOR (foo)->header.size.
101 (struct vectorlike_header): New type.
102 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
103 object, to help avoid aliasing.
104 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
105 (SUBRP): Likewise, since Lisp_Subr is a special case.
106 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
107 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
108 (struct Lisp_Hash_Table): Combine first two members into a single
109 struct vectorlike_header member. All uses of "size" and "next" members
110 changed to be "header.size" and "header.next".
111 * buffer.h (struct buffer): Likewise.
112 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
113 * frame.h (struct frame): Likewise.
114 * process.h (struct Lisp_Process): Likewise.
115 * termhooks.h (struct terminal): Likewise.
116 * window.c (struct save_window_data, struct saved_window): Likewise.
117 * window.h (struct window): Likewise.
118 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
119 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
120 * buffer.c (init_buffer_once): Likewise.
121 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
123 * process.c (Fformat_network_address): Use local var for size,
126 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
128 Make the Lisp reader and string-to-float more consistent (Bug#8525)
129 * data.c (atof): Remove decl; no longer used or needed.
130 (digit_to_number): Move to lread.c.
131 (Fstring_to_number): Use new string_to_number function, to be
132 consistent with how the Lisp reader treats infinities and NaNs.
133 Do not assume that floating-point numbers represent EMACS_INT
134 without losing information; this is not true on most 64-bit hosts.
135 Avoid double-rounding errors, by insisting on integers when
136 parsing non-base-10 numbers, as the documentation specifies.
137 * lisp.h (string_to_number): New decl, replacing ...
138 (isfloat_string): Remove.
139 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
140 (read1): Do not accept +. and -. as integers; this
141 appears to have been a coding error. Similarly, do not accept
142 strings like +-1e0 as floating point numbers. Do not report
143 overflow for integer overflows unless the base is not 10 which
144 means we have no simple and reliable way to continue.
145 Break out the floating-point parsing into a new
146 function string_to_number, so that Fstring_to_number parses
147 floating point numbers consistently with the Lisp reader.
148 (digit_to_number): Moved here from data.c. Make it static inline.
149 (E_CHAR, EXP_INT): Remove, replacing with ...
150 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
151 (string_to_number): New function, replacing isfloat_string.
152 This function checks for valid syntax and produces the resulting
153 Lisp float number too. Rework it so that string-to-number
154 no longer mishandles examples like "1.0e+". Use strtoumax,
155 so that overflow for non-base-10 numbers is reported only when
156 there's no portable and simple way to convert to floating point.
158 * textprop.c (set_text_properties_1): Rewrite for clarity,
159 and to avoid GCC warning about integer overflow.
161 * intervals.h (struct interval): Use EMACS_INT for members
162 where EMACS_UINT might cause problems. See
163 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
164 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
165 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
167 (offset_intervals): Tell GCC not to worry about length overflow
168 when negating a negative length.
170 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
171 (overrun_check_free): Likewise.
173 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
174 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
177 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
178 (gnutls_make_error): Rename local to avoid shadowing.
179 (gnutls_emacs_global_deinit): ifdef out; not used.
180 (Fgnutls_boot): Use const for pointer to readonly storage.
181 Comment out unused local. Fix pointer signedness problems.
183 * lread.c (openp): Don't stuff size_t into an 'int'.
184 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
185 about possible signed overflow.
187 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
188 (GDK_KEY_g): Don't define if already defined.
189 (xg_prepare_tooltip): Avoid pointer signedness problem.
190 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
192 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
193 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
195 * xfns.c (Fx_window_property): Simplify a bit,
196 to make a bit faster and to avoid GCC 4.6.0 warning.
197 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
199 * fns.c (internal_equal): Don't assume size_t fits in int.
201 * alloc.c (compact_small_strings): Tighten assertion a little.
203 Replace pEd with more-general pI, and fix some printf arg casts.
204 * lisp.h (pI): New macro, generalizing old pEd macro to other
205 conversion specifiers. For example, use "...%"pI"d..." rather
207 (pEd): Remove. All uses replaced with similar uses of pI.
208 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
209 * alloc.c (check_pure_size): Don't overflow by converting size to int.
210 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
211 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
212 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
213 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
214 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
216 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
217 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
218 * print.c (safe_debug_print, print_object): Likewise.
219 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
221 Use pI instead of if-then-else-abort. Use %p to avoid casts,
222 avoiding the 0 flag, which is not portable.
223 * process.c (Fmake_network_process): Use pI to avoid cast.
224 * region-cache.c (pp_cache): Likewise.
225 * xdisp.c (decode_mode_spec): Likewise.
226 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
227 behavior on 64-bit hosts with printf arg.
228 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
229 (x_stop_queuing_selection_requests): Likewise.
230 (x_get_window_property): Don't truncate byte count to an 'int'
233 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
234 here, since it parses constructs like leading '-' and spaces,
235 which are not wanted; and it overflows with large numbers.
236 Instead, simply match F[0-9]+, which is what is wanted anyway.
238 * alloc.c: Remove unportable assumptions about struct layout.
239 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
240 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
241 (allocate_vectorlike, make_pure_vector): Use the new macros,
242 plus offsetof, to remove unportable assumptions about struct layout.
243 These assumptions hold on all porting targets that I know of, but
244 they are not guaranteed, they're easy to remove, and removing them
245 makes further changes easier.
247 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
248 This doesn't fix a bug but makes the code clearer.
249 (string_overrun_cookie): Now const. Use initializers that
250 don't formally overflow signed char, to avoid warnings.
251 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
252 can cause Emacs to crash when string overrun checking is enabled.
253 (allocate_buffer): Don't assume sizeof (struct buffer) is a
254 multiple of sizeof (EMACS_INT); it need not be, if
255 alignof(EMACS_INT) < sizeof (EMACS_INT).
256 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
258 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
260 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
262 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
264 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
265 supposed to be handshaking. (Bug#8556)

285 2011-04-25 Eli Zaretskii <eliz@gnu.org>
287 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
288 "cast to pointer from integer of different size".
290 Improve doprnt and its use in verror. (Bug#8545)
291 * doprnt.c (doprnt): Document the set of format control sequences
292 supported by the function. Use SAFE_ALLOCA instead of always
295 * eval.c (verror): Don't limit the buffer size at size_max-1, that
296 is one byte too soon. Don't use xrealloc; instead xfree and
299 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
301 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
304 * gnutls.c: Renamed global_initialized to
305 gnutls_global_initialized. Added internals for the
306 :verify-hostname-error, :verify-error, and :verify-flags
307 parameters of `gnutls-boot' and documented those parameters in the
308 docstring. Start callback support.
309 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
310 unless a fatal error occured. Call gnutls_alert_send_appropriate
311 on error. Return error code.
312 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
313 (emacs_gnutls_read): Likewise.
314 (Fgnutls_boot): Return handshake error code.
315 (emacs_gnutls_handle_error): New function.
316 (wsaerror_to_errno): Likewise.
318 * w32.h (emacs_gnutls_pull): Add prototype.
319 (emacs_gnutls_push): Likewise.
321 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
322 (emacs_gnutls_push): Likewise.
324 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
326 * process.c (wait_reading_process_output): Check if GnuTLS
327 buffered some data internally if no FDs are set for TLS
330 * makefile.w32-in (OBJ2): Add gnutls.$(O).
331 (LIBS): Link to USER_LIBS.

383 * doprnt.c: Include limits.h.
384 (SIZE_MAX): New macro.

387 Improve overflow protection. Support `l' modifier for integer
388 conversions. Support %l conversion. Don't assume an EMACS_INT
389 argument for integer conversions and for %c.
391 * lisp.h (doprnt): Restore prototype.
393 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

398 * deps.mk (doprnt.o): Add back prerequisites.
399 (callint.o): Depend on character.h.
401 * eval.c (internal_lisp_condition_case): Include the handler
402 representation in the error message.
403 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
404 when breaking from the loop.
406 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
408 * callint.c (Fcall_interactively): When displaying error message
409 about invalid control letter, pass the character's codepoint, not
410 a pointer to its multibyte form. Improve display of the character
411 in octal and display also its hex code.
413 * character.c (char_string): Use %x to display the (unsigned)
414 codepoint of an invalid character, to avoid displaying a bogus
417 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
418 `error', not SYMBOL_NAME itself.
420 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
421 character arguments to `error'.
423 * charset.c (check_iso_charset_parameter): Fix incorrect argument
424 to `error' in error message about FINAL_CHAR argument. Make sure
425 FINAL_CHAR is a character, and use %c when it is passed as
428 2011-04-23 Eli Zaretskii <eliz@gnu.org>

490 Define only if needed.
492 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
493 by pacifying GCC about it. Maybe it's time to retire it?

984 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
985 was inaccessible from Lisp.
986 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
987 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
989 alloc.c: Import and export fewer symbols, and remove unused items.
990 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
992 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
993 it's not optimized away by whole-program optimization.
994 (message_enable_multibyte, free_misc): Remove.
995 (catchlist, handlerlist, mark_backtrace):
996 Declare only if BYTE_MARK_STACK.
997 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
998 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
999 (message_enable_multibyte): Remove decl.
1000 (free_misc, interval_free_list, float_block, float_block_index):
1001 (n_float_blocks, float_free_list, cons_block, cons_block_index):
1002 (cons_free_list, last_marked_index):
1004 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
1005 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
1006 (mark_backtrace): Define only if BYTE_MARK_STACK.
1007 * xdisp.c (message_enable_multibyte): Now static.
1009 Declare Lisp_Object Q* variables to be 'static' if not exported.
1010 This makes it easier for human readers (and static analyzers)
1011 to see whether these variables are used from other modules.
1012 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
1013 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
1014 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
1015 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

1017 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
1018 * xmenu.c, xselect.c:
1019 Declare Q* vars static if they are not used in other modules.
1020 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
1021 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
1022 Remove decls of unexported vars.
1023 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
1025 * lisp.h (DEFINE_FUNC): Make sname 'static'.
1027 Make Emacs functions such as Fatom 'static' by default.
1028 This makes it easier for human readers (and static analyzers)
1029 to see whether these functions can be called from other modules.
1030 DEFUN now defines a static function. To make the function external
1031 so that it can be used in other C modules, use the new macro DEFUE.
1032 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
1033 (Finit_image_library):
1034 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
1035 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
1036 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
1037 Remove decls, since these functions are now static.
1038 (Funintern, Fget_internal_run_time): New decls, since these functions
1039 were already external.
1041 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
1042 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
1043 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
1044 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
1045 * keyboard.c, keymap.c, lread.c:
1046 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
1047 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
1048 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
1049 Mark functions with DEFUE instead of DEFUN,
1050 if they are used in other modules.
1051 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
1052 decls for now-static functions.
1053 * buffer.h (Fdelete_overlay): Remove decl.
1054 * callproc.c (Fgetenv_internal): Mark as internal.
1055 * composite.c (Fremove_list_of_text_properties): Remove decl.

1059 * doc.c (Fdocumntation_property): New forward static decl.
1060 * eval.c (Ffetch_bytecode): New forward static decl.
1061 (Funintern): Remove extern decl; now in .h file where it belongs.
1062 * fileio.c (Fmake_symbolic_link): New forward static decl.
1063 * image.c (Finit_image_library): New forward static decl.
1064 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
1065 * intervals.h (Fprevious_property_change):
1066 (Fremove_list_of_text_properties): Remove decls.
1067 * keyboard.c (Fthis_command_keys): Remove decl.
1068 (Fcommand_execute): New forward static decl.
1069 * keymap.c (Flookup_key): New forward static decl.
1070 (Fcopy_keymap): Now static.
1071 * keymap.h (Flookup_key): Remove decl.
1072 * process.c (Fget_process): New forward static decl.
1073 (Fprocess_datagram_address): Mark as internal.
1074 * syntax.c (Fsyntax_table_p): New forward static decl.
1075 (skip_chars): Remove duplicate decl.

1080 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
1082 * editfns.c (Fformat): Remove unreachable code.
1084 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
1086 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
1089 2011-04-13 Eli Zaretskii <eliz@gnu.org>
1091 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
1092 when at ZV. (Bug#8487)
1094 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
1096 * charset.c (Fclear_charset_maps): Use xfree instead of free.
1098 * keyboard.c (parse_tool_bar_item): Likewise.
1099 * sound.c (sound_cleanup, alsa_close): Likewise.
1100 * termcap.c (tgetent): Likewise.
1101 * xfns.c (x_default_font_parameter): Likewise.
1102 * xsettings.c (read_and_apply_settings): Likewise.
1104 * alloc.c (overrun_check_malloc, overrun_check_realloc)
1105 (overrun_check_free): Protoize.
1107 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
1109 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
1110 since callers should never pass a negative size.
1111 Change the signature to match that of plain 'read' and 'write'; see
1112 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
1113 * lisp.h: Update prototypes of emacs_write and emacs_read.
1115 2011-04-11 Eli Zaretskii <eliz@gnu.org>
1117 * xdisp.c (redisplay_window): Don't try to determine the character
1118 position of the scroll margin if the window start point w->startp
1119 is outside the buffer's accessible region. (Bug#8468)
1121 2011-04-10 Eli Zaretskii <eliz@gnu.org>
1123 Fix write-region and its subroutines for buffers > 2GB.
1124 * fileio.c (a_write, e_write): Modify declaration of arguments and
1125 local variables to support buffers larger than 2GB.
1126 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
1128 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
1129 argument, local variables, and return value.
1131 * lisp.h: Update prototypes of emacs_write and emacs_read.
1133 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
1135 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
1137 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
1139 Fix more problems found by GCC 4.6.0's static checks.
1141 * xdisp.c (vmessage): Use a better test for character truncation.
1143 * charset.c (load_charset_map): <, not <=, for optimization,
1144 and to avoid potential problems with integer overflow.
1145 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
1146 * casetab.c (set_identity, shuffle): Likewise.
1147 * editfns.c (Fformat): Likewise.
1148 * syntax.c (skip_chars): Likewise.
1150 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
1151 This also lets GCC 4.6.0 generate slightly better loop code.
1153 * callint.c (Fcall_interactively): <, not <=, for optimization.
1154 (Fcall_interactively): Count the number of arguments produced,
1155 not the number of arguments given. This is simpler and lets GCC
1156 4.6.0 generate slightly better code.
1158 * ftfont.c: Distingish more carefully between FcChar8 and char.
1159 The previous code passed unsigned char * to a functions like
1160 strlen and xstrcasecmp that expect char *, which does not
1161 conform to the C standard.
1162 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
1163 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
1164 char * when the C standard requires it.
1166 * keyboard.c (read_char): Remove unused var.
1168 * eval.c: Port to Windows vsnprintf (Bug#8435).
1170 (SIZE_MAX): Define if the headers do not.
1171 (verror): Do not give up if vsnprintf returns a negative count.
1172 Instead, grow the buffer. This ports to Windows vsnprintf, which
1173 does not conform to C99. Problem reported by Eli Zaretskii.
1174 Also, simplify the allocation scheme, by avoiding the need for
1175 calling realloc, and removing the ALLOCATED variable.
1177 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
1179 Remove invocations of doprnt, as Emacs now uses vsnprintf.
1180 But keep the doprint source code for now, as we might revamp it
1181 and use it again (Bug#8435).
1182 * lisp.h (doprnt): Remove.
1183 * Makefile.in (base_obj): Remove doprnt.o.
1184 * deps.mk (doprnt.o): Remove.
1186 error: Print 32- and 64-bit integers portably (Bug#8435).
1187 Without this change, on typical 64-bit hosts error ("...%d...", N)
1188 was used to print both 32- and 64-bit integers N, which relied on
1190 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
1192 * lisp.h (error, verror): Mark as printf-like functions.
1193 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
1194 Report overflow in size calculations when allocating printf buffer.
1195 Do not truncate output string at its first null byte.
1196 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
1197 Truncate the output at a character boundary, since vsnprintf does not
1199 * charset.c (check_iso_charset_parameter): Convert internal
1200 character to string before calling 'error', since %c now has the
1202 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
1203 overflow when computing char to be passed to 'error'. Do not
1204 pass Lisp_Object to 'error'; pass the integer instead.
1205 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
1206 formatted with plain %d.
1208 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
1210 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
1212 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
1214 * xterm.c (x_catch_errors): Remove duplicate declaration.
1216 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
1218 * xdisp.c, lisp.h (message_nolog): Remove; unused.
1220 2011-04-10 Jim Meyering <meyering@redhat.com>
1222 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
1223 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
1224 return ssize_t not "int", and use size_t as the buffer length.
1225 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
1226 * gnutls.h: Update declarations.
1227 * process.c (read_process_output): Use ssize_t, to match.
1228 (send_process): Likewise.
1230 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
1232 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
1234 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
1236 * ftfont.c (get_adstyle_property, ftfont_pattern_entity): Use
1237 unsigned char, to match FcChar8 type definition.
1239 * xterm.c (handle_one_xevent):
1240 * xmenu.c (create_and_show_popup_menu):
1241 * xselect.c (x_decline_selection_request)
1242 (x_reply_selection_request): Avoid type-punned deref of X events.
1244 2011-04-09 Eli Zaretskii <eliz@gnu.org>
1246 Fix some uses of `int' instead of EMACS_INT.
1247 * search.c (string_match_1, fast_string_match)
1248 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
1249 (scan_buffer, find_next_newline_no_quit)
1250 (find_before_next_newline, search_command, Freplace_match)
1251 (Fmatch_data): Make some `int' variables be EMACS_INT.
1253 * xdisp.c (display_count_lines): 3rd argument and return value now
1254 EMACS_INT. All callers changed.
1255 (pint2hrstr): Last argument is now EMACS_INT.
1257 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
1258 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
1259 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
1260 (decode_coding_utf_16, decode_coding_emacs_mule)
1261 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
1262 (decode_coding_ccl, decode_coding_charset)
1263 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
1264 (decode_coding_iso_2022, decode_coding_emacs_mule)
1265 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
1266 <char_offset, last_offset>: Declare EMACS_INT.
1267 (encode_coding_utf_8, encode_coding_utf_16)
1268 (encode_coding_emacs_mule, encode_invocation_designation)
1269 (encode_designation_at_bol, encode_coding_iso_2022)
1270 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
1271 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
1273 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
1274 (encode_invocation_designation): Last argument P_NCHARS is now
1276 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
1277 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
1279 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
1282 * ccl.c (Fccl_execute_on_string): Declare some variables
1285 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

1293 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
1295 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
1297 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
1299 * keyboard.c (read_char): Call Lisp function help-form-show,
1300 instead of using internal_with_output_to_temp_buffer.
1301 (Qhelp_form_show): New var.
1302 (syms_of_keyboard): Use DEFSYM macro.
1304 * print.c (internal_with_output_to_temp_buffer): Function deleted.
1306 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
1308 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
1310 * process.c (Flist_processes): Removed to Lisp.
1311 (list_processes_1): Deleted.
1313 2011-04-06 Eli Zaretskii <eliz@gnu.org>
1315 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
1317 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
1319 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
1321 Fix more problems found by GCC 4.6.0's static checks.
1323 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
1325 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
1327 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
1329 * xdisp.c (vmessage): Mark as a printf-like function.
1331 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
1333 * sound.c (sound_warning): Don't crash if arg contains a printf format.
1335 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
1336 printf-like functions.
1337 (tiff_load): Add casts to remove these marks before passing them
1338 to system-supplied API.
1340 * eval.c (Fsignal): Remove excess argument to 'fatal'.
1342 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
1343 This avoids several warnings with gcc -Wstrict-overflow.
1344 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
1345 directly, rather than having caller test rule sign. This avoids
1346 some unnecessary tests.
1347 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
1348 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
1349 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
1351 * xfont.c (xfont_text_extents): Remove var that was set but not used.
1352 (xfont_open): Avoid unnecessary tests.
1354 * composite.c (composition_gstring_put_cache): Use unsigned integer.
1356 * composite.h, composite.c (composition_gstring_put_cache):
1357 Use EMACS_INT, not int, for length.
1359 * composite.h (COMPOSITION_DECODE_REFS): New macro,
1360 breaking out part of COMPOSITION_DECODE_RULE.
1361 (COMPOSITION_DECODE_RULE): Use it.
1362 * composite.c (get_composition_id): Remove unused local vars,
1363 by using the new macro.
1365 * textprop.c (set_text_properties_1): Change while to do-while,
1366 since the condition is always true at first.
1368 * intervals.c (graft_intervals_into_buffer): Mark var as used.
1369 (interval_deletion_adjustment): Return unsigned value.
1372 * process.c (list_processes_1, create_pty, read_process_output):
1373 (exec_sentinel): Remove vars that were set but not used.
1374 (create_pty): Remove unnecessary "volatile"s.
1375 (Fnetwork_interface_info): Avoid possibility of int overflow.

1381 * syntax.c (scan_words): Remove var that was set but not used.
1382 (update_syntax_table): Use unsigned instead of int.
1384 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
1385 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
1386 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
1388 * print.c (print_error_message): Avoid int overflow.
1390 * font.c (font_list_entities): Redo for clarity,
1391 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
1393 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
1394 (font_score): Avoid potential overflow in diff calculation.
1396 * fns.c (substring_both): Remove var that is set but not used.
1397 (sxhash): Redo loop for clarity and to avoid wraparound warning.
1399 * eval.c (funcall_lambda): Rename local to avoid shadowing.
1401 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
1402 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
1403 can always succeed if overflow has undefined behavior.
1405 * search.c (boyer_moore, wordify): Remove vars set but not used.
1406 (wordify): Omit three unnecessary tests.
1408 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
1409 All callers changed. This avoids the need for an unused var.
1411 * casefiddle.c (casify_region): Remove var that is set but not used.
1413 * dired.c (file_name_completion): Remove var that is set but not used.
1415 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
1417 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
1418 (Finsert_file_contents): Remove unnecessary code checking fd.
1420 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
1421 Check for integer overflow on size calculations.
1423 * buffer.c (Fprevious_overlay_change): Remove var that is set
1426 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
1427 Remove vars that are set but not used.
1428 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
1429 (timer_check_2): Mark vars as initialized.
1431 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
1433 * image.c (lookup_image): Remove var that is set but not used.
1434 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
1436 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
1437 that are set but not used.
1439 * xfns.c (make_invisible_cursor): Don't return garbage
1440 if XCreateBitmapFromData fails (Bug#8410).

1443 Remove vars that are set but not used.
1445 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
1446 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
1448 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
1449 Remove var that is set but not used.

1460 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
1461 All callers changed.
1462 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

1464 (decode_coding_charset): Remove vars that are set but not used.
1466 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
1467 that is set but not used.
1469 * print.c (print_object): Remove var that is set but not used.
1471 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
1472 The gnulib version avoids calling malloc in the usual case,
1473 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
1474 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
1475 * filelock.c (current_lock_owner): Likewise.
1476 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
1477 * sysdep.c: Include allocator.h, careadlinkat.h.

1500 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
1501 and thereabouts. All callers changed.
1502 (get_per_char_metric): Remove parameter `f', unused since
1503 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

1515 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
1517 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
1520 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
1522 Add lexical binding.
1524 * window.c (Ftemp_output_buffer_show): New fun.
1525 (Fsave_window_excursion):

1528 * lread.c (lisp_file_lexically_bound_p): New function.
1529 (Fload): Bind Qlexical_binding.
1530 (readevalloop): Remove `evalfun' arg.
1531 Bind Qinternal_interpreter_environment.
1532 (Feval_buffer): Bind Qlexical_binding.
1533 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
1535 (syms_of_lread): Declare `lexical-binding'.
1537 * lisp.h (struct Lisp_Symbol): New field `declared_special'.

1540 (menu_item_eval_property): Use it.
1542 * image.c (parse_image_spec): Use Ffunctionp.
1544 * fns.c (concat, mapcar1): Accept byte-code-functions.
1546 * eval.c (Fsetq): Handle lexical vars.
1547 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
1548 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
1549 (FletX, Flet): Obey lexical binding.
1550 (Fcommandp): Handle closures.
1551 (Feval): New `lexical' arg.
1552 (eval_sub): New function extracted from Feval. Use it almost
1553 everywhere where Feval was used. Look up vars in lexical env.
1555 (Ffunctionp): Move from subr.el.
1556 (Ffuncall): Handle closures.
1557 (apply_lambda): Remove `eval_flags'.
1558 (funcall_lambda): Handle closures and new byte-code-functions.
1559 (Fspecial_variable_p): New function.
1560 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
1561 but without exporting it to Lisp.
1563 * doc.c (Fdocumentation, store_function_docstring):
1564 * data.c (Finteractive_form): Handle closures.
1566 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
1569 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN): New
1571 (exec_byte_code): New function extracted from Fbyte_code to handle new
1572 calling convention for byte-code-functions. Add new byte-codes.

1584 * xdisp.c (SCROLL_LIMIT): New macro.
1585 (try_scrolling): Use it when setting scroll_limit. Limit
1586 scrolling to 100 screen lines.
1587 (redisplay_window): Even when falling back on "recentering",
1588 position point in the window according to scroll-conservatively,
1589 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
1591 (try_scrolling): When point is above the window, allow searching
1592 as far as scroll_max, or one screenful, to compute vertical
1593 distance from PT to the scroll margin position. This prevents
1594 try_scrolling from unnecessarily failing when
1595 scroll-conservatively is set to a value slightly larger than the
1596 window height. Clean up the case of PT below the margin at bottom
1597 of window: scroll_max can no longer be INT_MAX. When aggressive
1598 scrolling is in use, don't let point enter the opposite scroll
1599 margin as result of the scroll.
1600 (syms_of_xdisp) <scroll-conservatively>: Document the
1601 threshold of 100 lines for never-recentering scrolling.

1608 (message_log_check_duplicate): Remove parameters `prev_bol' and
1609 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
1610 (redisplay_internal): Remove parameter `preserve_echo_area',
1611 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
1613 * indent.c (Fvertical_motion):
1614 * window.c (window_scroll_pixel_based, Frecenter):
1615 Don't pass `need_y_p' to `move_it_by_lines'.
1617 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
1619 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
1620 steal a few bits to be more compact.
1621 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
1622 Remove unneeded casts.
1624 * bytecode.c (Fbyte_code): CAR and CDR can GC.
1626 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
1628 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
1629 binding" message (bug#7967).
1631 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
1633 Fix more problems found by GCC 4.6.0's static checks.
1635 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
1636 Remove unused local var.
1638 * editfns.c (Fmessage_box): Remove unused local var.
1640 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
1641 (note_mode_line_or_margin_highlight, note_mouse_highlight):
1642 Omit unused local vars.
1643 * window.c (shrink_windows): Omit unused local var.
1644 * menu.c (digest_single_submenu): Omit unused local var.
1645 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
1646 Omit unused local var.
1648 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
1649 Don't assume string length fits in int.

1651 (read_key_sequence): Don't check last_real_key_start redundantly.
1653 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
1654 instead of alloca (Bug#8344).
1656 * eval.c (Fbacktrace): Don't assume nargs fits in int.

1666 * cm.c (calccost): Turn while-do into do-while, for clarity.
1668 * keyboard.c (syms_of_keyboard): Use the same style as later
1669 in this function when indexing through an array. This also
1670 works around GCC bug 48267.
1672 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
1674 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
1676 * chartab.c (sub_char_table_ref_and_range): Redo for slight
1677 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
1679 * keyboard.c, keyboard.h (num_input_events): Now size_t.
1680 This avoids undefined behavior on integer overflow, and is a bit
1681 more convenient anyway since it is compared to a size_t variable.
1683 Variadic C functions now count arguments with size_t, not int.
1684 This avoids an unnecessary limitation on 64-bit machines, which
1685 caused (substring ...) to crash on large vectors (Bug#8344).
1686 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

1696 * frame.c (x_set_frame_parameters): Likewise.
1697 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
1698 0 if not found, not -1. All callers changed.
1700 * alloc.c (garbage_collect): Don't assume stack size fits in int.
1701 (stack_copy_size): Now size_t, not int.
1702 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
1704 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
1706 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
1707 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
1708 All callers changed.

1723 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
1724 don't set the hook to nil, but remove the offending function instead.
1725 (Qcommand_hook_internal): Remove, unused.
1726 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
1727 Vcommand_hook_internal.

1730 (funcall_nil, funcall_not): New functions.
1731 (run_hook_with_args): Call each function through a `funcall' argument.

1750 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
1751 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

1821 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
1822 (gap_left, gap_right): Don't call it.
1824 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
1826 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
1827 incurred during fontification.

1892 (uniscribe_check_otf): Remove unused variable `table'.
1893 (uniscribe_font_driver): Add missing initializers.
1895 2011-03-23 Julien Danjou <julien@danjou.info>
1897 * term.c (Fsuspend_tty, Fresume_tty):
1898 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
1899 * window.c (temp_output_buffer_show):
1900 * insdel.c (signal_before_change):
1901 * frame.c (Fhandle_switch_frame):
1902 * fileio.c (Fdo_auto_save):
1903 * emacs.c (Fkill_emacs):
1904 * editfns.c (save_excursion_restore):
1905 * cmds.c (internal_self_insert):
1906 * callint.c (Fcall_interactively):
1907 * buffer.c (Fkill_all_local_variables):
1908 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
1910 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
1911 unconditionnaly since it does the check itself.
1913 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
1915 Fix more problems found by GCC 4.5.2's static checks.
1917 * coding.c (encode_coding_raw_text): Avoid unnecessary test
1918 the first time through the loop, since we know p0 < p1 then.
1919 This also avoids a gcc -Wstrict-overflow warning.
1921 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
1922 leading to a memory leak, possible in functions like
1923 load_charset_map_from_file that can allocate an unbounded number
1924 of objects (Bug#8318).
1926 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
1927 that could (at least in theory) be that large.
1929 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
1930 This is less likely to overflow, and avoids undefined behavior if
1931 overflow does occur. All callers changed. Use strtoul to scan
1932 for the unsigned long integer.
1933 (pint2hrstr): Simplify and tune code slightly.
1934 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
1936 * scroll.c (do_scrolling): Work around GCC bug 48228.
1937 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

1940 This also avoids a warning with gcc -Wstrict-overflow.
1941 (validate_x_resource_name): Simplify count usage.
1942 This also avoids a warning with gcc -Wstrict-overflow.
1944 * fileio.c (Fcopy_file): Report error if fchown or fchmod
1947 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
1949 * process.c (Fmake_network_process): Use socklen_t, not int,
1950 where POSIX says socklen_t is required in portable programs.
1951 This fixes a porting bug on hosts like 64-bit HP-UX, where
1952 socklen_t is wider than int (Bug#8277).
1953 (Fmake_network_process, server_accept_connection):
1954 (wait_reading_process_output, read_process_output):

1964 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
1965 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
1967 Make tparam.h and terminfo.c consistent.
1968 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
1969 Include tparam.h instead, since it declares them.
1970 * cm.h (PC): Remove extern decl; tparam.h now does this.
1971 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
1972 * terminfo.c: Include tparam.h, to check interfaces.
1973 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
1974 (tparam): Adjust signature to match interface in tparam.h;
1975 this removes some undefined behavior. Check that outstring and len
1976 are zero, which they always are with Emacs.
1977 * tparam.h (PC, BC, UP): New extern decls.
1979 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
1980 (xftfont_open): Rename locals to avoid shadowing.
1982 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

1998 (composition_update_it): Mark var as initialized.
1999 (find_automatic_composition): Mark vars as initialized,
2000 with a FIXME (Bug#8290).
2002 character.h: Rename locals to avoid shadowing.
2003 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
2004 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
2005 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
2006 (BUF_DEC_POS): Be more systematic about renaming local temporaries
2009 * textprop.c (property_change_between_p): Remove; unused.
2011 * intervals.c (interval_start_pos): Now static.
2013 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
2015 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
2016 Rename locals to avoid shadowing.
2018 * sound.c (wav_play, au_play, Fplay_sound_internal):
2019 Fix pointer signedness.
2020 (alsa_choose_format): Remove unused local var.
2021 (wav_play): Initialize a variable to 0, to prevent undefined
2022 behavior (Bug#8278).
2024 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
2026 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
2028 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
2029 clobbering (Bug#8298).
2030 * sysdep.c (sys_subshell): Likewise.
2031 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
2033 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
2034 This should get cleaned up, so that child_setup has the
2035 same signature on all platforms.
2037 * callproc.c (call_process_cleanup): Now static.
2038 (relocate_fd): Rename locals to avoid shadowing.
2040 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
2042 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
2043 not to be necessary, and produces flickering.
2045 2011-03-20 Glenn Morris <rgm@gnu.org>
2047 * config.in: Remove file.
2049 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
2051 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
2052 are now in src/globals.h.
2053 (syms_of_minibuf): Remove spurious & from previous change.
2055 2011-03-20 Leo <sdl.web@gmail.com>
2057 * minibuf.c (completing-read-function): New variable.
2058 (completing-read-default): Rename from completing-read.
2059 (completing-read): Call completing-read-function.
2061 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
2063 * xfaces.c (Fx_load_color_file):
2064 Read color file from absolute filename (bug#8250).
2066 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
2068 * makefile.w32-in: Update dependencies.
2070 2011-03-17 Eli Zaretskii <eliz@gnu.org>
2072 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

2079 (sigchld_handler): Now static.
2081 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
2082 That way, the code declares only the vars that it needs.
2083 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
2084 * s/cygwin.h (PTY_ITERATION): Likewise.
2085 * s/darwin.h (PTY_ITERATION): Likewise.

2088 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
2089 * process.c (allocate_pty): Don't declare stb unless it's needed.
2091 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
2092 (CONSTANTLIM): Remove; unused.
2093 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
2094 Define only if needed.
2096 * unexelf.c (unexec): Name an expression,
2097 to avoid gcc -Wbad-function-cast warning.
2098 Use a different way to cause a compilation error if anyone uses
2099 n rather than nn, a way that does not involve shadowing.
2100 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
2102 * deps.mk (unexalpha.o): Remove; unused.
2104 New file unexec.h, the (simple) interface for unexec (Bug#8267).
2105 * unexec.h: New file.
2106 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
2107 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
2109 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
2110 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
2111 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

2121 * lread.c (read1): Rewrite so as not to use empty "else".
2122 (Fload, readevalloop, read1): Rename locals to avoid shadowing.
2124 * print.c (Fredirect_debugging_output): Fix pointer signedess.
2126 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
2127 warning when compiling print.c.
2129 * font.c (font_unparse_fcname): Abort in an "impossible" situation
2130 instead of using an uninitialized var.
2131 (font_sort_entities): Mark var as initialized.
2133 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
2135 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

2167 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
2168 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
2169 some of which prompt warnings from gcc -Wbad-function-cast.
2170 (Fformat_time_string, Fencode_time, Finsert_char):
2171 (Ftranslate_region_internal, Fformat):
2172 Rename or remove local vars to avoid shadowing.

2190 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
2191 Rename locals to avoid shadowing.
2192 (mark_stack): Move local variables into the #ifdef region where
2194 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
2195 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
2197 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
2198 (GC_STRING_CHARS): Remove; not used.
2199 (Fmemory_limit): Cast sbrk's returned value to char *.
2201 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
2202 avoids undefined behavior in theory.
2204 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
2206 Use functions, not macros, for up- and down-casing (Bug#8254).
2207 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
2208 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
2209 to use the following functions instead of these macros.
2210 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
2211 EMACS_INT, since callers assume the returned value fits in int.
2212 (upcase1): Likewise, for UPCASE_TABLE.
2213 (uppercasep, lowercasep, upcase): New static inline functions.
2214 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

2220 (regex_compile, re_search_2, re_match_2_internal):
2221 Remove unused local vars.
2222 (FREE_VAR): Rewrite so as not to use empty "else",
2223 which gcc can warn about.
2224 (regex_compile, re_match_2_internal): Mark locals as initialized.
2225 (RETALLOC_IF): Define only if needed.
2226 (WORDCHAR_P): Likewise. This one is never needed, but is used
2227 only in a comment talking about a compiler bug, so put inside
2228 the #if 0 of that comment.
2229 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
2230 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
2233 * search.c (boyer_moore): Rename locals to avoid shadowing.
2234 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
2235 (PREV_CHAR_BOUNDARY): Likewise.
2237 * search.c (simple_search): Remove unused var.
2239 * dired.c (compile_pattern): Move decl from here ...

2245 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
2247 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):

2252 (casify_region): Mark local as initialized.
2254 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
2256 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
2257 New macros, so that the caller can use some names other than
2258 gcpro1, gcpro2, etc.
2259 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
2261 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
2262 argument, for consistency with GCPRO2_VAR, etc: it is now the
2263 prefix of the variable, not the variable itself. All uses
2265 * dired.c (directory_files_internal, file_name_completion):
2266 Rename locals to avoid shadowing.
2268 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
2269 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
2270 dired.c's scmp function, had undefined behavior.
2271 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
2272 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
2273 * buffer.h: ... to here, because these macros use current_buffer,
2274 and the new implementation with inline functions needs to have
2275 current_buffer in scope now, rather than later when the macros
2277 (downcase, upcase1): New static inline functions.
2278 (DOWNCASE, UPCASE1): Reimplement using these functions.
2279 This avoids undefined behavior in expressions like
2280 DOWNCASE (x) == DOWNCASE (y), which previously suffered
2281 from race conditions in accessing the global variables
2282 case_temp1 and case_temp2.
2283 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
2284 * lisp.h (case_temp1, case_temp2): Remove their decls.
2285 * character.h (ASCII_CHAR_P): Move from here ...
2286 * lisp.h: ... to here, so that the inline functions mentioned
2289 * dired.c (directory_files_internal_unwind): Now static.
2291 * fileio.c (file_name_as_directory, directory_file_name):
2292 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
2294 (file_name_as_directory): Use const pointers when appropriate.
2295 (Fexpand_file_name): Likewise. In particular, newdir might
2296 point at constant storage, so make it a const pointer.
2297 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
2298 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
2300 (Fset_file_times, Finsert_file_contents, auto_save_error):
2301 Rename locals to avoid shadowing.
2303 * minibuf.c (choose_minibuf_frame_1): Now static.
2304 (Ftry_completion, Fall_completions): Rename or remove locals
2307 * marker.c (bytepos_to_charpos): Remove; unused.
2309 * lisp.h (verify_bytepos, count_markers): New decls,
2310 so that gcc does not warn that these functions aren't declared.
2312 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
2313 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
2314 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
2315 (copy_text): Remove unused local var.
2317 * filelock.c (within_one_second): Now static.
2318 (lock_file_1): Rename local to avoid shadowing.
2320 * buffer.c (fix_overlays_before): Mark locals as initialized.
2321 (fix_start_end_in_overlays): Likewise. This function should be
2322 simplified by using pointers-to-pointers, but that's a different
2324 (switch_to_buffer_1): Now static.
2325 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
2326 (report_overlay_modification): Rename locals to avoid shadowing.
2328 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
2329 Fix pointer signedness issue.
2330 (sys_subshell): Mark local as volatile if checking for lint,
2331 to suppress a gcc -Wclobbered warning that does not seem to be right.
2332 (MAXPATHLEN): Define only if needed.
2334 * process.c (serial_open, serial_configure): Move decls from here ...
2335 * systty.h: ... to here, so that they can be checked.
2337 * fns.c (get_random, seed_random): Move extern decls from here ...
2338 * lisp.h: ... to here, so that they can be checked.
2340 * sysdep.c (reset_io): Now static.
2341 (wait_for_termination_signal): Remove; unused.
2343 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
2344 (copy_keymap_item, append_key, push_text_char_description):
2346 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
2347 (DENSE_TABLE_SIZE): Remove; unused.
2348 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
2349 (describe_map_tree):
2350 Rename locals to avoid shadowing.
2352 * keyboard.c: Declare functions static if they are not used elsewhere.
2353 (echo_char, echo_dash, cmd_error, top_level_2):
2354 (poll_for_input, handle_async_input): Now static.
2355 (read_char, kbd_buffer_get_event, make_lispy_position):
2356 (make_lispy_event, make_lispy_movement, apply_modifiers):
2357 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
2358 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
2359 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
2360 (read_key_sequence, read_char): Mark locals as initialized.
2361 (Fexit_recursive_edit, Fabort_recursive_edit): Mark with NO_RETURN.
