1 2011-05-11 Paul Eggert <eggert@cs.ucla.edu>
2
3 * window.c (size_window): Avoid needless test at loop start.
4
5 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
6
7 * image.c (Finit_image_library): Return t for built-in image types,
8 like pbm and xbm. (Bug#8640)
9
10 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11
12 * w32menu.c (set_frame_menubar): Fix submenu allocation.
13
14 2011-05-07 Eli Zaretskii <eliz@gnu.org>
15
16 * w32console.c (Fset_screen_color): Doc fix.
17 (Fget_screen_color): New function.
18 (syms_of_ntterm): Defsubr it.
19
20 * callproc.c (call_process_cleanup): Don't close and unlink the
21 temporary file if Fcall_process didn't create it in the first
22 place.
23 (Fcall_process): Don't create tempfile if stdout of the child
24 process will be redirected to a file specified with `:file'.
25 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
26 cue to call_process_cleanup not to close that handle.
27
28 2011-05-07 Ben Key <bkey76@gmail.com>
29
30 * makefile.w32-in: The bootstrap-temacs rule now makes use of
31 one of two shell specific rules, either bootstrap-temacs-CMD or
32 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
33 to the previous implementation of the bootstrap-temacs rule.
34 The bootstrap-temacs-CMD rule is similar to the previous
35 implementation of the bootstrap-temacs rule except that it
36 makes use of the ESC_CFLAGS variable instead of the CFLAGS
37 variable.
38
39 These changes, along with some changes to nt/configure.bat,
40 nt/gmake.defs, and nt/nmake.defs, are required to extend my
41 earlier fix to add support for --cflags and --ldflags options
42 that include quotes so that it works whether make uses cmd or
43 sh as the shell.
44
45 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
46
47 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
48 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
49 is a constant.
50 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
51 a string. Handle both cases.
52 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
53 (Fdbus_register_method): Use Qinvalid_function.
54
55 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
56
57 * makefile.w32-in: Update dependencies.
58 (LISP_H): Add inttypes.h and stdin.h.
59 (PROCESS_H): Add unistd.h.
60
61 2011-05-06 Eli Zaretskii <eliz@gnu.org>
62
63 * lread.c: Include limits.h (fixes the MS-Windows build broken by
64 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
65
66 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
67
68 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
69
70 * term.c (vfatal): Remove stray call to va_end.
71 It's not needed and the C Standard doesn't allow it here anyway.
72
73 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
74 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
75
76 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
77 bytes.
78
79 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
80
81 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
82
83 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
84
85 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
86
87 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
88
89 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
90 * charset.c (Fdefine_charset_internal): Don't initialize
91 charset.code_space[15]. The value was garbage, on hosts with
92 32-bit int (Bug#8600).
93
94 * lread.c (read_integer): Be more consistent with string-to-number.
95 Use string_to_number to do the actual conversion; this avoids
96 rounding errors and fixes some other screwups. Without this fix,
97 for example, #x1fffffffffffffff was misread as -2305843009213693952.
98 (digit_to_number): Move earlier, for benefit of read_integer.
99 Return -1 if the digit is out of range for the base, -2 if it is
100 not a digit in any supported base. (Bug#8602)
101
102 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
103
104 * dispnew.c (scrolling_window): Return 1 if we scrolled,
105 to match comment at start of function. This also removes a
106 GCC warning about overflow in a 32+64-bit port.
107
108 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
109
110 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
111 Reported by Stefan Monnier in
112 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
113 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages): Use
114 SYMBOLP-guarded XSYMBOL, not XPNTR.
115
116 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
117 (EMACS_UINTPTR): Likewise, with uintptr_t.
118
119 * lisp.h: Prefer 64-bit EMACS_INT if available.
120 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
121 on 32-bit hosts that have 64-bit int, so that they can access
122 large files.
123 However, temporarily disable this change unless the temporary
124 symbol WIDE_EMACS_INT is defined.
125
126 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
127
128 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
129 This removes an assumption that EMACS_INT and long are the same
130 width as pointers. The assumption is true for Emacs porting targets
131 now, but we want to make other targets possible.
132 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
133 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
134 In the rest of the code, change types of integers that hold casted
135 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
136 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
137 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
138 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
139 No need to cast type when ORing.
140 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
141 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
142 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
143 assume EMACS_INT is the same width as char *.
144 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
145 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
146 Remove no-longer-needed casts.
147 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
148 (xg_tool_bar_help_callback, xg_make_tool_item):
149 Use EMACS_INTPTR to hold an integer
150 that will be cast to void *; this can avoid a GCC warning
151 if EMACS_INT is not the same width as void *.
152 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
153 * xdisp.c (display_echo_area_1, resize_mini_window_1):
154 (current_message_1, set_message_1):
155 Use a local to convert to proper width without a cast.
156 * xmenu.c (dialog_selection_callback): Likewise.
157
158 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
159 Also, don't assume VALBITS / RAND_BITS is less than 5,
160 and don't rely on undefined behavior when shifting a 1 left into
161 the sign bit.
162 * lisp.h (get_random): Change signature to match.
163
164 * lread.c (hash_string): Use size_t, not int, for hash computation.
165 Normally we prefer signed values; but hashing is special, because
166 it's better to use unsigned division on hash table sizes so that
167 the remainder is nonnegative. Also, size_t is the natural width
168 for hashing into memory. The previous code used 'int', which doesn't
169 retain enough info to hash well into very large tables.
170 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
171
172 * dbusbind.c: Don't possibly lose pointer info when converting.
173 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
174 Use XPNTR rather than XHASH, so that the high-order bits of
175 the pointer aren't lost when converting through void *.
176
177 * eval.c (Fautoload): Don't double-shift a pointer.
178
179 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
180
181 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
182
183 * gnutls.c (DEF_GNUTLS_FN):
184 * image.c (DEF_IMGLIB_FN): Make function pointers static.
185
186 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
187
188 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
189 marker. (Bug#8610)
190
191 2011-05-05 Eli Zaretskii <eliz@gnu.org>
192
193 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
194 New version that can reserve upto 2GB of heap space.
195
196 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
197
198 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
199
200 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
201
202 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
203 `gnutls_certificate_set_x509_key_file'.
204
205 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

213 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
214 Remove unused parameter `fildes'.
215 * process.c (read_process_output, send_process): Don't pass it.
216
217 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
218
219 Fix previous change: the library cache is defined in w32.c.
220 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
221 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

268 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
269
270 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

302
303 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
304
305 * sysdep.c (interruptible_wait_for_termination): New function
306 which is like wait_for_termination, but allows keyboard
307 interruptions.
308
309 * callproc.c (Fcall_process): Add (:file "file") as an option for
310 the STDOUT buffer.
311 (Fcall_process_region): Ditto.
312
313 2011-04-30 Eli Zaretskii <eliz@gnu.org>
314
315 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
316 rather than `XVECTOR (FOO)->size'.
317
318 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
319 inttypes.h, as a gnulib replacement is used if it not available in
320 system headers.
321
322 2011-04-21 Eli Zaretskii <eliz@gnu.org>
323
324 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

344 simple variables to record original value of point. (Bug#7952)
345
346 * doprnt.c (doprnt): Fix the case where a multibyte sequence
347 produced by %s or %c overflows available buffer space. (Bug#8545)
348
349 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
350
351 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

367
368 * doprnt.c (doprnt): Don't return value smaller than the buffer
369 size if the message was truncated. (Bug#8545).
370
371 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
372
373 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

383
384 2011-04-27 Eli Zaretskii <eliz@gnu.org>
385
386 Improve `doprnt' and its usage. (Bug#8545)
387 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
388 `format_end'. Remove support for %l as a conversion specifier.
389 Don't use xrealloc. Improve diagnostics when the %l size modifier
390 is used. Update the commentary.
391
392 * eval.c (verror): Simplify calculation of size_t.
393
394 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
395 messages.
396
397 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
398
399 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
400 change.
401
402 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
403
404 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
405 This makes this file independent of the recent pseudovector change.
406
407 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
408
409 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
410
411 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
412 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
413 Remove unused local.
414 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
415
416 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
417 GCC 4.6.0 optimizes based on type-based alias analysis. For
418 example, if b is of type struct buffer * and v of type struct
419 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
420 != &v->size, and therefore "v->size = 1; b->size = 2; return
421 v->size;" must therefore return 1. This assumption is incorrect
422 for Emacs, since it type-puns struct Lisp_Vector * with many other
423 types. To fix this problem, this patch adds a new type struct
424 vectorlike_header that documents the constraints on layout of vectors
425 and pseudovectors, and helps optimizing compilers not get fooled
426 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
427 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
428 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
429 the size member.
430 (XSETPVECTYPE): Rewrite in terms of new macro.
431 (XSETPVECTYPESIZE): New macro, specifying both type and size.
432 This is a bit clearer, and further avoids the possibility of
433 undesirable aliasing.
434 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
435 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
436 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
437 since Lisp_Subr is a special case (no "next" field).
438 (ASIZE): Now uses header.size rather than size. All
439 previous uses of XVECTOR (foo)->size replaced to use this macro,
440 to avoid the hassle of writing XVECTOR (foo)->header.size.
441 (struct vectorlike_header): New type.
442 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
443 object, to help avoid aliasing.
444 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
445 (SUBRP): Likewise, since Lisp_Subr is a special case.
446 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
447 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
448 (struct Lisp_Hash_Table): Combine first two members into a single
449 struct vectorlike_header member. All uses of "size" and "next" members
450 changed to be "header.size" and "header.next".
451 * buffer.h (struct buffer): Likewise.
452 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
453 * frame.h (struct frame): Likewise.
454 * process.h (struct Lisp_Process): Likewise.
455 * termhooks.h (struct terminal): Likewise.
456 * window.c (struct save_window_data, struct saved_window): Likewise.
457 * window.h (struct window): Likewise.
458 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
459 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
460 * buffer.c (init_buffer_once): Likewise.
461 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
462 special case.
463 * process.c (Fformat_network_address): Use local var for size,
464 for brevity.
465
466 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
467
468 Make the Lisp reader and string-to-float more consistent (Bug#8525)
469 * data.c (atof): Remove decl; no longer used or needed.
470 (digit_to_number): Move to lread.c.
471 (Fstring_to_number): Use new string_to_number function, to be
472 consistent with how the Lisp reader treats infinities and NaNs.
473 Do not assume that floating-point numbers represent EMACS_INT
474 without losing information; this is not true on most 64-bit hosts.
475 Avoid double-rounding errors, by insisting on integers when
476 parsing non-base-10 numbers, as the documentation specifies.
477 * lisp.h (string_to_number): New decl, replacing ...
478 (isfloat_string): Remove.
479 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
480 (read1): Do not accept +. and -. as integers; this
481 appears to have been a coding error. Similarly, do not accept
482 strings like +-1e0 as floating point numbers. Do not report
483 overflow for integer overflows unless the base is not 10 which
484 means we have no simple and reliable way to continue.
485 Break out the floating-point parsing into a new
486 function string_to_number, so that Fstring_to_number parses
487 floating point numbers consistently with the Lisp reader.
488 (digit_to_number): Moved here from data.c. Make it static inline.
489 (E_CHAR, EXP_INT): Remove, replacing with ...
490 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
491 (string_to_number): New function, replacing isfloat_string.
492 This function checks for valid syntax and produces the resulting
493 Lisp float number too. Rework it so that string-to-number
494 no longer mishandles examples like "1.0e+". Use strtoumax,
495 so that overflow for non-base-10 numbers is reported only when
496 there's no portable and simple way to convert to floating point.
497
498 * textprop.c (set_text_properties_1): Rewrite for clarity,
499 and to avoid GCC warning about integer overflow.
500
501 * intervals.h (struct interval): Use EMACS_INT for members
502 where EMACS_UINT might cause problems. See
503 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
504 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
505 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
506 All uses changed.
507 (offset_intervals): Tell GCC not to worry about length overflow
508 when negating a negative length.
509
510 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
511 (overrun_check_free): Likewise.
512
513 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
514 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
515 word size.
516
517 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
518 (gnutls_make_error): Rename local to avoid shadowing.
519 (gnutls_emacs_global_deinit): ifdef out; not used.
520 (Fgnutls_boot): Use const for pointer to readonly storage.
521 Comment out unused local. Fix pointer signedness problems.
522
523 * lread.c (openp): Don't stuff size_t into an 'int'.
524 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
525 about possible signed overflow.
526
527 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
528 (GDK_KEY_g): Don't define if already defined.
529 (xg_prepare_tooltip): Avoid pointer signedness problem.
530 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
531
532 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
533 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
534
535 * xfns.c (Fx_window_property): Simplify a bit,
536 to make a bit faster and to avoid GCC 4.6.0 warning.
537 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
538
539 * fns.c (internal_equal): Don't assume size_t fits in int.
540
541 * alloc.c (compact_small_strings): Tighten assertion a little.
542
543 Replace pEd with more-general pI, and fix some printf arg casts.
544 * lisp.h (pI): New macro, generalizing old pEd macro to other
545 conversion specifiers. For example, use "...%"pI"d..." rather
546 than "...%"pEd"...".
547 (pEd): Remove. All uses replaced with similar uses of pI.
548 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
549 * alloc.c (check_pure_size): Don't overflow by converting size to int.
550 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
551 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
552 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
553 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
554 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
555 64-bit hosts.
556 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
557 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
558 * print.c (safe_debug_print, print_object): Likewise.
559 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
560 to int.
561 Use pI instead of if-then-else-abort. Use %p to avoid casts,
562 avoiding the 0 flag, which is not portable.
563 * process.c (Fmake_network_process): Use pI to avoid cast.
564 * region-cache.c (pp_cache): Likewise.
565 * xdisp.c (decode_mode_spec): Likewise.
566 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
567 behavior on 64-bit hosts with printf arg.
568 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
569 (x_stop_queuing_selection_requests): Likewise.
570 (x_get_window_property): Don't truncate byte count to an 'int'
571 when tracing.
572
573 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
574 here, since it parses constructs like leading '-' and spaces,
575 which are not wanted; and it overflows with large numbers.
576 Instead, simply match F[0-9]+, which is what is wanted anyway.
577
578 * alloc.c: Remove unportable assumptions about struct layout.
579 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
580 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
581 (allocate_vectorlike, make_pure_vector): Use the new macros,
582 plus offsetof, to remove unportable assumptions about struct layout.
583 These assumptions hold on all porting targets that I know of, but
584 they are not guaranteed, they're easy to remove, and removing them
585 makes further changes easier.
586
587 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
588 This doesn't fix a bug but makes the code clearer.
589 (string_overrun_cookie): Now const. Use initializers that
590 don't formally overflow signed char, to avoid warnings.
591 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
592 can cause Emacs to crash when string overrun checking is enabled.
593 (allocate_buffer): Don't assume sizeof (struct buffer) is a
594 multiple of sizeof (EMACS_INT); it need not be, if
595 alignof(EMACS_INT) < sizeof (EMACS_INT).
596 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
597
598 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

613 (handle_user_signal): Break into debugger when debug-on-event
614 matches the current signal symbol.
615
616 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
617
618 * alloc.c (check_sblock, check_string_bytes)
619 (check_string_free_list): Convert to standard C.
620
621 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>

624
625 2011-04-25 Eli Zaretskii <eliz@gnu.org>
626
627 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
628 "cast to pointer from integer of different size".
629
630 Improve doprnt and its use in verror. (Bug#8545)
631 * doprnt.c (doprnt): Document the set of format control sequences
632 supported by the function. Use SAFE_ALLOCA instead of always
633 using `alloca'.
634
635 * eval.c (verror): Don't limit the buffer size at size_max-1, that
636 is one byte too soon. Don't use xrealloc; instead xfree and
637 xmalloc anew.
638
639 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
640
641 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
642 callbacks stage.
643
644 * gnutls.c: Renamed global_initialized to
645 gnutls_global_initialized. Added internals for the
646 :verify-hostname-error, :verify-error, and :verify-flags
647 parameters of `gnutls-boot' and documented those parameters in the
648 docstring. Start callback support.
649 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
650 unless a fatal error occured. Call gnutls_alert_send_appropriate
651 on error. Return error code.
652 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
653 (emacs_gnutls_read): Likewise.
654 (Fgnutls_boot): Return handshake error code.

711 changes in globals.h immediately force recompilation.
712 (TAGS): Depend on $(CURDIR)/m/intel386.h and
713 $(CURDIR)/s/ms-w32.h.
714 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
715
716 * character.c (Fchar_direction): Function deleted.
717 (syms_of_character): Don't defsubr it.
718 <char-direction-table>: Deleted.
719
720 2011-04-23 Eli Zaretskii <eliz@gnu.org>
721
722 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
723 * doprnt.c: Include limits.h.
724 (SIZE_MAX): New macro.
725 (doprnt): Return a size_t value. 2nd arg is now size_t. Many
726 local variables are now size_t instead of int or unsigned.
727 Improve overflow protection. Support `l' modifier for integer
728 conversions. Support %l conversion. Don't assume an EMACS_INT
729 argument for integer conversions and for %c.
730
731 * lisp.h (doprnt): Restore prototype.
732
733 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

742 representation in the error message.
743 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
744 when breaking from the loop.
745
746 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
747
748 * callint.c (Fcall_interactively): When displaying error message
749 about invalid control letter, pass the character's codepoint, not
750 a pointer to its multibyte form. Improve display of the character
751 in octal and display also its hex code.
752
753 * character.c (char_string): Use %x to display the (unsigned)
754 codepoint of an invalid character, to avoid displaying a bogus
755 negative value.
756
757 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
758 `error', not SYMBOL_NAME itself.
759
760 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
761 character arguments to `error'.
762
763 * charset.c (check_iso_charset_parameter): Fix incorrect argument
764 to `error' in error message about FINAL_CHAR argument. Make sure
765 FINAL_CHAR is a character, and use %c when it is passed as
766 argument to `error'.

830 Define only if needed.
831
832 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
833 by pacifying GCC about it. Maybe it's time to retire it?
834 * xfaces.c (USG, __TIMEVAL__): Likewise.
835
836 * dispextern.h (struct redisplay_interface): Rename param
837 to avoid shadowing.
838 * termhooks.h (struct terminal): Likewise.
839 * xterm.c (xembed_send_message): Likewise.

842 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
843
844 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
845 it.
846
847 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
848 so that we aren't warned about unused symbols.
849
850 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
851
852 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

866
867 * xmenu.c (menu_help_callback): Pointer type fixes.
868 Use const pointers when pointing at readonly data. Avoid pointer
869 signedness clashes.

918

954
955 * nsfont.m: Fixed bugs in ns_get_family and
956 ns_descriptor_to_entity that were caused by using free to
957 deallocate memory blocks that were allocated by xmalloc (via
958 xstrdup). This caused Emacs to crash when compiled with
959 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
960 --enable-checking=xmallocoverrun). xfree is now used to
961 deallocate these memory blocks.

1302 * ccl.c (Vccl_program_table): Now static.
1303 (check_ccl_update): Remove; unused.
1304
1305 * category.c (SET_CATEGORY_SET, set_category_set): Move here.

1311
1312 * buffer.c (buffer_count): Remove unused var.
1313
1314 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
1315 so that it's not optimized away.
1316 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
1317 * dispextern.h (bidi_dump_cached_states): Remove, since it's
1318 exported only to the debugger.
1319
1320 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
1321 * atimer.h (run_all_atimers): Removed; not exported.
1322
1323 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
1324 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
1325 was inaccessible from Lisp.
1326 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
1327 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
1328
1329 alloc.c: Import and export fewer symbols, and remove unused items.
1330 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
1331 is defined.
1332 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
1333 it's not optimized away by whole-program optimization.
1334 (message_enable_multibyte, free_misc): Remove.
1335 (catchlist, handlerlist, mark_backtrace):
1336 Declare only if BYTE_MARK_STACK.

1338 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
1339 (message_enable_multibyte): Remove decl.
1340 (free_misc, interval_free_list, float_block, float_block_index):
1341 (n_float_blocks, float_free_list, cons_block, cons_block_index):
1342 (cons_free_list, last_marked_index):
1343 Now static.
1344 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
1345 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
1346 (mark_backtrace): Define only if BYTE_MARK_STACK.
1347 * xdisp.c (message_enable_multibyte): Now static.
1348
1349 Declare Lisp_Object Q* variables to be 'static' if not exported.
1350 This makes it easier for human readers (and static analyzers)
1351 to see whether these variables are used from other modules.
1352 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
1353 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
1354 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

1361 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
1362 Remove decls of unexported vars.
1363 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
1364
1365 * lisp.h (DEFINE_FUNC): Make sname 'static'.
1366
1367 Make Emacs functions such as Fatom 'static' by default.
1368 This makes it easier for human readers (and static analyzers)
1369 to see whether these functions can be called from other modules.
1370 DEFUN now defines a static function. To make the function external
1371 so that it can be used in other C modules, use the new macro DEFUE.
1372 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
1373 (Finit_image_library):
1374 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
1375 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
1376 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
1377 Remove decls, since these functions are now static.
1378 (Funintern, Fget_internal_run_time): New decls, since these functions
1379 were already external.
1380
1381 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
1382 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

1387 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
1388 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
1389 Mark functions with DEFUE instead of DEFUN,
1390 if they are used in other modules.
1391 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
1392 decls for now-static functions.
1393 * buffer.h (Fdelete_overlay): Remove decl.
1394 * callproc.c (Fgetenv_internal): Mark as internal.
1395 * composite.c (Fremove_list_of_text_properties): Remove decl.
1396 (Fcomposition_get_gstring): New forward static decl.

1406 (Fremove_list_of_text_properties): Remove decls.
1407 * keyboard.c (Fthis_command_keys): Remove decl.
1408 (Fcommand_execute): New forward static decl.
1409 * keymap.c (Flookup_key): New forward static decl.
1410 (Fcopy_keymap): Now static.
1411 * keymap.h (Flookup_key): Remove decl.
1412 * process.c (Fget_process): New forward static decl.
1413 (Fprocess_datagram_address): Mark as internal.

1421

1423
1424 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
1425
1426 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
1427 change. (Bug#8496)
1428
1429 2011-04-13 Eli Zaretskii <eliz@gnu.org>
1430
1431 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
1432 when at ZV. (Bug#8487)
1433
1434 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
1435
1436 * charset.c (Fclear_charset_maps): Use xfree instead of free.
1437 (Bug#8437)
1438 * keyboard.c (parse_tool_bar_item): Likewise.
1439 * sound.c (sound_cleanup, alsa_close): Likewise.
1440 * termcap.c (tgetent): Likewise.
1441 * xfns.c (x_default_font_parameter): Likewise.
1442 * xsettings.c (read_and_apply_settings): Likewise.
1443
1444 * alloc.c (overrun_check_malloc, overrun_check_realloc)
1445 (overrun_check_free): Protoize.
1446
1447 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
1448
1449 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
1450 since callers should never pass a negative size.
1451 Change the signature to match that of plain 'read' and 'write'; see
1452 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
1453 * lisp.h: Update prototypes of emacs_write and emacs_read.
1454
1455 2011-04-11 Eli Zaretskii <eliz@gnu.org>
1456
1457 * xdisp.c (redisplay_window): Don't try to determine the character
1458 position of the scroll margin if the window start point w->startp
1459 is outside the buffer's accessible region. (Bug#8468)
1460
1461 2011-04-10 Eli Zaretskii <eliz@gnu.org>
1462
1463 Fix write-region and its subroutines for buffers > 2GB.
1464 * fileio.c (a_write, e_write): Modify declaration of arguments and
1465 local variables to support buffers larger than 2GB.
1466 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
1467
1468 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
1469 argument, local variables, and return value.
1470
1471 * lisp.h: Update prototypes of emacs_write and emacs_read.
1472
1473 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
1474
1475 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
1476
1477 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
1478
1479 Fix more problems found by GCC 4.6.0's static checks.
1480
1481 * xdisp.c (vmessage): Use a better test for character truncation.
1482
1483 * charset.c (load_charset_map): <, not <=, for optimization,
1484 and to avoid potential problems with integer overflow.
1485 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
1486 * casetab.c (set_identity, shuffle): Likewise.
1487 * editfns.c (Fformat): Likewise.
1488 * syntax.c (skip_chars): Likewise.
1489
1490 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
1491 This also lets GCC 4.6.0 generate slightly better loop code.
1492
1493 * callint.c (Fcall_interactively): <, not <=, for optimization.
1494 (Fcall_interactively): Count the number of arguments produced,
1495 not the number of arguments given. This is simpler and lets GCC
1496 4.6.0 generate slightly better code.
1497
1498 * ftfont.c: Distingish more carefully between FcChar8 and char.
1499 The previous code passed unsigned char * to a functions like
1500 strlen and xstrcasecmp that expect char *, which does not
1501 conform to the C standard.
1502 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
1503 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
1504 char * when the C standard requires it.
1505
1506 * keyboard.c (read_char): Remove unused var.
1507
1508 * eval.c: Port to Windows vsnprintf (Bug#8435).
1509 Include <limits.h>.
1510 (SIZE_MAX): Define if the headers do not.
1511 (verror): Do not give up if vsnprintf returns a negative count.
1512 Instead, grow the buffer. This ports to Windows vsnprintf, which
1513 does not conform to C99. Problem reported by Eli Zaretskii.
1514 Also, simplify the allocation scheme, by avoiding the need for
1515 calling realloc, and removing the ALLOCATED variable.
1516
1517 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
1518
1519 Remove invocations of doprnt, as Emacs now uses vsnprintf.
1520 But keep the doprint source code for now, as we might revamp it
1521 and use it again (Bug#8435).
1522 * lisp.h (doprnt): Remove.
1523 * Makefile.in (base_obj): Remove doprnt.o.
1524 * deps.mk (doprnt.o): Remove.
1525
1526 error: Print 32- and 64-bit integers portably (Bug#8435).
1527 Without this change, on typical 64-bit hosts error ("...%d...", N)
1528 was used to print both 32- and 64-bit integers N, which relied on
1529 undefined behavior.
1530 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
1531 New macro.
1532 * lisp.h (error, verror): Mark as printf-like functions.
1533 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
1534 Report overflow in size calculations when allocating printf buffer.
1535 Do not truncate output string at its first null byte.
1536 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
1537 Truncate the output at a character boundary, since vsnprintf does not
1538 do that.
1539 * charset.c (check_iso_charset_parameter): Convert internal
1540 character to string before calling 'error', since %c now has the
1541 printf meaning.
1542 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
1543 overflow when computing char to be passed to 'error'. Do not
1544 pass Lisp_Object to 'error'; pass the integer instead.
1545 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
1546 formatted with plain %d.
1547
1548 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
1549
1550 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
1551
1552 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
1553
1554 * xterm.c (x_catch_errors): Remove duplicate declaration.
1555
1556 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
1557
1558 * xdisp.c, lisp.h (message_nolog): Remove; unused.
1559
1560 2011-04-10 Jim Meyering <meyering@redhat.com>
1561
1562 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
1563 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
1564 return ssize_t not "int", and use size_t as the buffer length.
1565 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
1566 * gnutls.h: Update declarations.
1567 * process.c (read_process_output): Use ssize_t, to match.
1568 (send_process): Likewise.
1569
1570 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
1571
1572 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
1573
1574 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
1575
1576 * ftfont.c (get_adstyle_property, ftfont_pattern_entity): Use
1577 unsigned char, to match FcChar8 type definition.
1578
1579 * xterm.c (handle_one_xevent):
1580 * xmenu.c (create_and_show_popup_menu):
1581 * xselect.c (x_decline_selection_request)
1582 (x_reply_selection_request): Avoid type-punned deref of X events.
1583
1584 2011-04-09 Eli Zaretskii <eliz@gnu.org>
1585
1586 Fix some uses of `int' instead of EMACS_INT.
1587 * search.c (string_match_1, fast_string_match)
1588 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
1589 (scan_buffer, find_next_newline_no_quit)
1590 (find_before_next_newline, search_command, Freplace_match)
1591 (Fmatch_data): Make some `int' variables be EMACS_INT.
1592
1593 * xdisp.c (display_count_lines): 3rd argument and return value now
1594 EMACS_INT. All callers changed.
1595 (pint2hrstr): Last argument is now EMACS_INT.
1596
1597 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
1598 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
1599 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
1600 (decode_coding_utf_16, decode_coding_emacs_mule)
1601 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
1602 (decode_coding_ccl, decode_coding_charset)

1604 (decode_coding_iso_2022, decode_coding_emacs_mule)
1605 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
1606 <char_offset, last_offset>: Declare EMACS_INT.
1607 (encode_coding_utf_8, encode_coding_utf_16)
1608 (encode_coding_emacs_mule, encode_invocation_designation)
1609 (encode_designation_at_bol, encode_coding_iso_2022)
1610 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
1611 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
1612 Declare EMACS_INT.
1613 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
1614 (encode_invocation_designation): Last argument P_NCHARS is now
1615 EMACS_INT.
1616 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
1617 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
1618
1619 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
1620 All users changed.
1621
1622 * ccl.c (Fccl_execute_on_string): Declare some variables
1623 EMACS_INT.
1624
1625 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

1632
1633 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
1634
1635 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
1636
1637 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
1638
1639 * keyboard.c (read_char): Call Lisp function help-form-show,
1640 instead of using internal_with_output_to_temp_buffer.
1641 (Qhelp_form_show): New var.
1642 (syms_of_keyboard): Use DEFSYM macro.
1643
1644 * print.c (internal_with_output_to_temp_buffer): Function deleted.
1645
1646 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
1647
1648 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
1649
1650 * process.c (Flist_processes): Removed to Lisp.
1651 (list_processes_1): Deleted.
1652
1653 2011-04-06 Eli Zaretskii <eliz@gnu.org>
1654
1655 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
1656
1657 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
1658
1659 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
1660
1661 Fix more problems found by GCC 4.6.0's static checks.
1662
1663 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
1664
1665 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
1666
1667 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
1668
1669 * xdisp.c (vmessage): Mark as a printf-like function.
1670
1671 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
1672
1673 * sound.c (sound_warning): Don't crash if arg contains a printf format.
1674
1675 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
1676 printf-like functions.
1677 (tiff_load): Add casts to remove these marks before passing them
1678 to system-supplied API.
1679
1680 * eval.c (Fsignal): Remove excess argument to 'fatal'.
1681
1682 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
1683 This avoids several warnings with gcc -Wstrict-overflow.
1684 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
1685 directly, rather than having caller test rule sign. This avoids
1686 some unnecessary tests.
1687 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
1688 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
1689 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
1690
1691 * xfont.c (xfont_text_extents): Remove var that was set but not used.
1692 (xfont_open): Avoid unnecessary tests.
1693
1694 * composite.c (composition_gstring_put_cache): Use unsigned integer.

1700 breaking out part of COMPOSITION_DECODE_RULE.
1701 (COMPOSITION_DECODE_RULE): Use it.
1702 * composite.c (get_composition_id): Remove unused local vars,
1703 by using the new macro.
1704
1705 * textprop.c (set_text_properties_1): Change while to do-while,
1706 since the condition is always true at first.
1707
1708 * intervals.c (graft_intervals_into_buffer): Mark var as used.
1709 (interval_deletion_adjustment): Return unsigned value.
1710 All uses changed.
1711
1712 * process.c (list_processes_1, create_pty, read_process_output):
1713 (exec_sentinel): Remove vars that were set but not used.
1714 (create_pty): Remove unnecessary "volatile"s.
1715 (Fnetwork_interface_info): Avoid possibility of int overflow.

1723
1724 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
1725 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
1726 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
1727
1728 * print.c (print_error_message): Avoid int overflow.
1729
1730 * font.c (font_list_entities): Redo for clarity,
1731 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
1732
1733 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
1734 (font_score): Avoid potential overflow in diff calculation.
1735
1736 * fns.c (substring_both): Remove var that is set but not used.
1737 (sxhash): Redo loop for clarity and to avoid wraparound warning.
1738
1739 * eval.c (funcall_lambda): Rename local to avoid shadowing.
1740
1741 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
1742 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
1743 can always succeed if overflow has undefined behavior.
1744
1745 * search.c (boyer_moore, wordify): Remove vars set but not used.
1746 (wordify): Omit three unnecessary tests.
1747
1748 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

1774 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
1775
1776 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
1777 that are set but not used.
1778
1779 * xfns.c (make_invisible_cursor): Don't return garbage
1780 if XCreateBitmapFromData fails (Bug#8410).
1781
1782 * xselect.c (x_get_local_selection, x_handle_property_notify):
1783 Remove vars that are set but not used.
1784
1785 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
1786 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
1787
1788 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
1789 Remove var that is set but not used.
1790 (scroll_bar_windows_size): Now size_t, not int.
1791 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
1792 Check for overflow.
1793
1794 * xfaces.c (realize_named_face): Remove vars that are set but not used.
1795 (map_tty_color) [!defined MSDOS]: Likewise.
1796
1797 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
1798
1799 * coding.c: Remove vars that are set but not used.
1800 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
1801 All callers changed.
1802 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
1803 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
1804 (decode_coding_charset): Remove vars that are set but not used.
1805
1806 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
1807 that is set but not used.
1808
1809 * print.c (print_object): Remove var that is set but not used.
1810
1811 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
1812 The gnulib version avoids calling malloc in the usual case,
1813 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
1814 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
1815 * filelock.c (current_lock_owner): Likewise.
1816 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
1817 * sysdep.c: Include allocator.h, careadlinkat.h.
1818 (emacs_no_realloc_allocator): New static constant.
1819 (emacs_readlink): New function.
1820 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
1821 ../lib/careadlinkat.h.
1822
1823 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
1824
1825 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
1826 first non-nil return value).
1827
1828 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
1829
1830 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
1831 if not defined (Bug#8403).
1832
1833 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
1834
1835 * xdisp.c (display_count_lines): Remove parameter `start',
1836 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
1837 (get_char_face_and_encoding): Remove parameter `multibyte_p',
1838 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

1850
1851 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
1852
1853 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
1854
1855 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
1856
1857 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
1858 later (Bug#8403).
1859
1860 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
1861
1862 Add lexical binding.
1863
1864 * window.c (Ftemp_output_buffer_show): New fun.
1865 (Fsave_window_excursion):
1866 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
1867
1868 * lread.c (lisp_file_lexically_bound_p): New function.
1869 (Fload): Bind Qlexical_binding.
1870 (readevalloop): Remove `evalfun' arg.
1871 Bind Qinternal_interpreter_environment.
1872 (Feval_buffer): Bind Qlexical_binding.
1873 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
1874 Mark as dynamic.
1875 (syms_of_lread): Declare `lexical-binding'.
1876
1877 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
1878
1879 * keyboard.c (eval_dyn): New fun.
1880 (menu_item_eval_property): Use it.
1881
1882 * image.c (parse_image_spec): Use Ffunctionp.
1883
1884 * fns.c (concat, mapcar1): Accept byte-code-functions.
1885
1886 * eval.c (Fsetq): Handle lexical vars.
1887 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
1888 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
1889 (FletX, Flet): Obey lexical binding.
1890 (Fcommandp): Handle closures.
1891 (Feval): New `lexical' arg.
1892 (eval_sub): New function extracted from Feval. Use it almost
1893 everywhere where Feval was used. Look up vars in lexical env.
1894 Handle closures.
1895 (Ffunctionp): Move from subr.el.
1896 (Ffuncall): Handle closures.
1897 (apply_lambda): Remove `eval_flags'.
1898 (funcall_lambda): Handle closures and new byte-code-functions.
1899 (Fspecial_variable_p): New function.
1900 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
1901 but without exporting it to Lisp.
1902
1903 * doc.c (Fdocumentation, store_function_docstring):
1904 * data.c (Finteractive_form): Handle closures.
1905
1906 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
1907 interactive spec.
1908
1909 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN): New
1910 byte-codes.
1911 (exec_byte_code): New function extracted from Fbyte_code to handle new
1912 calling convention for byte-code-functions. Add new byte-codes.
1913
1914 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
1915
1916 * alloc.c (Fmake_symbol): Init new `declared_special' field.
1917
1918 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
1919
1920 * xdisp.c (redisplay_internal): Fix prototype.
1921
1922 2011-03-31 Eli Zaretskii <eliz@gnu.org>
1923
1924 * xdisp.c (SCROLL_LIMIT): New macro.
1925 (try_scrolling): Use it when setting scroll_limit. Limit
1926 scrolling to 100 screen lines.
1927 (redisplay_window): Even when falling back on "recentering",
1928 position point in the window according to scroll-conservatively,
1929 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
1930
1931 (try_scrolling): When point is above the window, allow searching
1932 as far as scroll_max, or one screenful, to compute vertical
1933 distance from PT to the scroll margin position. This prevents
1934 try_scrolling from unnecessarily failing when
1935 scroll-conservatively is set to a value slightly larger than the
1936 window height. Clean up the case of PT below the margin at bottom
1937 of window: scroll_max can no longer be INT_MAX. When aggressive
1938 scrolling is in use, don't let point enter the opposite scroll
1939 margin as result of the scroll.
1940 (syms_of_xdisp) <scroll-conservatively>: Document the
1941 threshold of 100 lines for never-recentering scrolling.
1942
1943 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
1944
1945 * dispextern.h (move_it_by_lines):
1946 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
1947 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
1948 (message_log_check_duplicate): Remove parameters `prev_bol' and
1949 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
1950 (redisplay_internal): Remove parameter `preserve_echo_area',
1951 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
1952
1953 * indent.c (Fvertical_motion):
1954 * window.c (window_scroll_pixel_based, Frecenter):
1955 Don't pass `need_y_p' to `move_it_by_lines'.
1956
1957 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
1958
1959 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
1960 steal a few bits to be more compact.
1961 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
1962 Remove unneeded casts.
1963
1964 * bytecode.c (Fbyte_code): CAR and CDR can GC.
1965
1966 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
1967
1968 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
1969 binding" message (bug#7967).
1970
1971 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
1972
1973 Fix more problems found by GCC 4.6.0's static checks.
1974
1975 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
1976 Remove unused local var.
1977
1978 * editfns.c (Fmessage_box): Remove unused local var.
1979
1980 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
1981 (note_mode_line_or_margin_highlight, note_mouse_highlight):
1982 Omit unused local vars.
1983 * window.c (shrink_windows): Omit unused local var.
1984 * menu.c (digest_single_submenu): Omit unused local var.
1985 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
1986 Omit unused local var.
1987
1988 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
1989 Don't assume string length fits in int.
1990 (keyremap_step, read_key_sequence): Use size_t for sizes.
1991 (read_key_sequence): Don't check last_real_key_start redundantly.
1992
1993 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
1994 instead of alloca (Bug#8344).

1997 (Fbacktrace_frame): Don't assume nframes fits in int.
1998
1999 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
2000
2001 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
2002 concerns.
2003
2004 * term.c (produce_glyphless_glyph): Remove unnecessary test.
2005

2007
2008 * keyboard.c (syms_of_keyboard): Use the same style as later
2009 in this function when indexing through an array. This also
2010 works around GCC bug 48267.
2011
2012 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
2013
2014 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
2015

2017 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
2018
2019 * keyboard.c, keyboard.h (num_input_events): Now size_t.
2020 This avoids undefined behavior on integer overflow, and is a bit
2021 more convenient anyway since it is compared to a size_t variable.
2022
2023 Variadic C functions now count arguments with size_t, not int.
2024 This avoids an unnecessary limitation on 64-bit machines, which
2025 caused (substring ...) to crash on large vectors (Bug#8344).
2026 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
2027 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

2033 (internal_condition_case_n, run_hook_with_args, apply_lambda)
2034 (funcall_lambda, mark_backtrace): Likewise.
2035 * fns.c (concat): Likewise.
2036 * frame.c (x_set_frame_parameters): Likewise.
2037 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
2038 0 if not found, not -1. All callers changed.
2039
2040 * alloc.c (garbage_collect): Don't assume stack size fits in int.
2041 (stack_copy_size): Now size_t, not int.
2042 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

2051 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
2052 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
2053 * character.h (CHAR_TO_BYTE8):
2054 * cmds.c (internal_self_insert):
2055 * editfns.c (general_insert_function):
2056 * keymap.c (push_key_description):
2057 * search.c (Freplace_match):
2058 * xdisp.c (message_dolog, set_message_1): All callers changed.
2059
2060 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
2061
2062 * keyboard.c (safe_run_hook_funcall): New function.
2063 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
2064 don't set the hook to nil, but remove the offending function instead.
2065 (Qcommand_hook_internal): Remove, unused.
2066 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
2067 Vcommand_hook_internal.
2068
2069 * eval.c (enum run_hooks_condition): Remove.
2070 (funcall_nil, funcall_not): New functions.
2071 (run_hook_with_args): Call each function through a `funcall' argument.
2072 Remove `cond' argument, now redundant.

2074 (Frun_hook_with_args_until_failure): Adjust accordingly.
2075 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

2080
2081 * print.c (strout): Remove parameter `multibyte', unused since
2082 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.

2085 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
2086 All callers changed.
2087
2088 * w32.c (_wsa_errlist): Use braces for struct initializers.
2089
2090 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

2254
2255 Fix more problems found by GCC 4.5.2's static checks.
2256
2257 * coding.c (encode_coding_raw_text): Avoid unnecessary test
2258 the first time through the loop, since we know p0 < p1 then.
2259 This also avoids a gcc -Wstrict-overflow warning.
2260
2261 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
2262 leading to a memory leak, possible in functions like

2265
2266 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
2267 that could (at least in theory) be that large.
2268
2269 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
2270 This is less likely to overflow, and avoids undefined behavior if
2271 overflow does occur. All callers changed. Use strtoul to scan
2272 for the unsigned long integer.

2288
2289 * process.c (Fmake_network_process): Use socklen_t, not int,
2290 where POSIX says socklen_t is required in portable programs.
2291 This fixes a porting bug on hosts like 64-bit HP-UX, where
2292 socklen_t is wider than int (Bug#8277).
2293 (Fmake_network_process, server_accept_connection):
2294 (wait_reading_process_output, read_process_output):

2306
2307 Make tparam.h and terminfo.c consistent.
2308 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
2309 Include tparam.h instead, since it declares them.
2310 * cm.h (PC): Remove extern decl; tparam.h now does this.
2311 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
2312 * terminfo.c: Include tparam.h, to check interfaces.
2313 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
2314 (tparam): Adjust signature to match interface in tparam.h;
2315 this removes some undefined behavior. Check that outstring and len
2316 are zero, which they always are with Emacs.
2317 * tparam.h (PC, BC, UP): New extern decls.
2318
2319 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

2345 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
2346 (BUF_DEC_POS): Be more systematic about renaming local temporaries
2347 to avoid shadowing.

2361 (wav_play): Initialize a variable to 0, to prevent undefined
2362 behavior (Bug#8278).
2363
2364 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
2365
2366 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
2367
2368 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
2369 clobbering (Bug#8298).
2370 * sysdep.c (sys_subshell): Likewise.
2371 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
2372
2373 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
2374 This should get cleaned up, so that child_setup has the
2375 same signature on all platforms.
2376
2377 * callproc.c (call_process_cleanup): Now static.
2378 (relocate_fd): Rename locals to avoid shadowing.

2380 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
2381
2382 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
2383 not to be necessary, and produces flickering.

2526 Mark variables as initialized.
2527 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
2528
2529 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
2530 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
2531 Rename locals to avoid shadowing.
2532 (mark_stack): Move local variables into the #ifdef region where
2533 they're used.
2534 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
2535 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
2536 needed otherwise.
2537 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
2538 (GC_STRING_CHARS): Remove; not used.
2539 (Fmemory_limit): Cast sbrk's returned value to char *.
2540
2541 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
2542 avoids undefined behavior in theory.
2543
2544 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
2545
2546 Use functions, not macros, for up- and down-casing (Bug#8254).
2547 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
2548 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
2549 to use the following functions instead of these macros.
2550 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
2551 EMACS_INT, since callers assume the returned value fits in int.
2552 (upcase1): Likewise, for UPCASE_TABLE.
2553 (uppercasep, lowercasep, upcase): New static inline functions.
2554 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
2555 the race-condition problem in the old DOWNCASE.
2556
2557 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
2558 Rename locals to avoid shadowing.
2559 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
2560 (regex_compile, re_search_2, re_match_2_internal):
2561 Remove unused local vars.
2562 (FREE_VAR): Rewrite so as not to use empty "else",
2563 which gcc can warn about.
2564 (regex_compile, re_match_2_internal): Mark locals as initialized.
2565 (RETALLOC_IF): Define only if needed.
2566 (WORDCHAR_P): Likewise. This one is never needed, but is used
2567 only in a comment talking about a compiler bug, so put inside
2568 the #if 0 of that comment.
2569 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
2570 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
2571 Remove; unused.
2572
2573 * search.c (boyer_moore): Rename locals to avoid shadowing.
2574 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
2575 (PREV_CHAR_BOUNDARY): Likewise.
2576
2577 * search.c (simple_search): Remove unused var.
2578
2579 * dired.c (compile_pattern): Move decl from here ...
2580 * lisp.h: ... to here, so that it can be checked.
2581 (struct re_registers): New forward decl.
2582
2583 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
2584
2585 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
2586 All uses changed.
2587 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
2588 Rename locals to avoid shadowing.
2589 (Fvertical_motion): Mark locals as initialized.
2590
2591 * casefiddle.c (casify_object, casify_region): Now static.
2592 (casify_region): Mark local as initialized.
2593
2594 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
2595
2596 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
2597 New macros, so that the caller can use some names other than
2598 gcpro1, gcpro2, etc.
2599 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
2600 of the new macros.
2601 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
2602 argument, for consistency with GCPRO2_VAR, etc: it is now the
2603 prefix of the variable, not the variable itself. All uses
2604 changed.
2605 * dired.c (directory_files_internal, file_name_completion):
2606 Rename locals to avoid shadowing.
2607
2608 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
2609 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
2610 dired.c's scmp function, had undefined behavior.
2611 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
2612 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
2613 * buffer.h: ... to here, because these macros use current_buffer,
2614 and the new implementation with inline functions needs to have
2615 current_buffer in scope now, rather than later when the macros
2616 are used.
2617 (downcase, upcase1): New static inline functions.
2618 (DOWNCASE, UPCASE1): Reimplement using these functions.
2619 This avoids undefined behavior in expressions like
2620 DOWNCASE (x) == DOWNCASE (y), which previously suffered
2621 from race conditions in accessing the global variables
2622 case_temp1 and case_temp2.
2623 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
2624 * lisp.h (case_temp1, case_temp2): Remove their decls.
2625 * character.h (ASCII_CHAR_P): Move from here ...
2626 * lisp.h: ... to here, so that the inline functions mentioned
2627 above can use them.
2628
2629 * dired.c (directory_files_internal_unwind): Now static.
2630
2631 * fileio.c (file_name_as_directory, directory_file_name):
2632 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
2633 Now static.
2634 (file_name_as_directory): Use const pointers when appropriate.
2635 (Fexpand_file_name): Likewise. In particular, newdir might
2636 point at constant storage, so make it a const pointer.
2637 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
2638 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
2639 signedness issues.
2640 (Fset_file_times, Finsert_file_contents, auto_save_error):
2641 Rename locals to avoid shadowing.
2642
2643 * minibuf.c (choose_minibuf_frame_1): Now static.
2644 (Ftry_completion, Fall_completions): Rename or remove locals
2645 to avoid shadowing.
2646
2647 * marker.c (bytepos_to_charpos): Remove; unused.
2648
2649 * lisp.h (verify_bytepos, count_markers): New decls,
2650 so that gcc does not warn that these functions aren't declared.
2651
2652 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
2653 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
2654 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
2655 (copy_text): Remove unused local var.
2656
2657 * filelock.c (within_one_second): Now static.
2658 (lock_file_1): Rename local to avoid shadowing.
2659
2660 * buffer.c (fix_overlays_before): Mark locals as initialized.
2661 (fix_start_end_in_overlays): Likewise. This function should be
2662 simplified by using pointers-to-pointers, but that's a different
2663 matter.
2664 (switch_to_buffer_1): Now static.
2665 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
2666 (report_overlay_modification): Rename locals to avoid shadowing.
2667
2668 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
2669 Fix pointer signedness issue.
2670 (sys_subshell): Mark local as volatile if checking for lint,
2671 to suppress a gcc -Wclobbered warning that does not seem to be right.
2672 (MAXPATHLEN): Define only if needed.
2673
2674 * process.c (serial_open, serial_configure): Move decls from here ...
2675 * systty.h: ... to here, so that they can be checked.
2676
2677 * fns.c (get_random, seed_random): Move extern decls from here ...
2678 * lisp.h: ... to here, so that they can be checked.
2679
2680 * sysdep.c (reset_io): Now static.
2681 (wait_for_termination_signal): Remove; unused.
2682
2683 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
2684 (copy_keymap_item, append_key, push_text_char_description):
2685 Now static.
2686 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
2687 (DENSE_TABLE_SIZE): Remove; unused.
2688 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
2689 (describe_map_tree):
2690 Rename locals to avoid shadowing.
2691
2692 * keyboard.c: Declare functions static if they are not used elsewhere.
2693 (echo_char, echo_dash, cmd_error, top_level_2):
2694 (poll_for_input, handle_async_input): Now static.
2695 (read_char, kbd_buffer_get_event, make_lispy_position):
2696 (make_lispy_event, make_lispy_movement, apply_modifiers):
2697 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

2706
2707 * lisp.h (force_auto_save_soon): New decl.
2708
2709 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
2710 (DEFINE_DUMMY_FUNCTION): New macro.
2711 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
2712 Use it.
2713 (main): Add casts to avoid warnings
2714 if GCC considers string literals to be constants.
2715
2716 * lisp.h (fatal_error_signal): Add decl, since it's exported.
2717
2718 * dbusbind.c: Pointer signedness fixes.
2719 (xd_signature, xd_append_arg, xd_initialize):
2720 (Fdbus_call_method, Fdbus_call_method_asynchronously):

2839 For example, without this patch (encode-time 0 0 0 1 1
2840 1152921504606846976) returns the obviously-bogus value (-948597
2841 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
2842 reports time overflow. See
