142
143 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
144 for sizes. Check for string overflow more accurately.
145 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.

154
155 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
156
157 * lread.c: Integer overflow fixes.
158 (read_integer): Radix is now EMACS_INT, not int,
159 to improve quality of diagnostics for out-of-range radices.
160 Calculate buffer size correctly for out-of-range radices.
161 (read1): Check for integer overflow in radices, and in
162 read-circle numbers.
163 (read_escape): Avoid int overflow.
164 (Fload, openp, read_buffer_size, read1)
165 (substitute_object_recurse, read_vector, read_list, map_obarray):

180
181 2011-06-22 Leo Liu <sdl.web@gmail.com>
182

184 Move to minibuffer.el.
185
186 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
187
188 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
189 The following patches are for when GLYPH_DEBUG && !XASSERT.
190 * dispextern.h (trace_redisplay_p, dump_glyph_string):
191 * dispnew.c (flush_stdout):
192 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
193 Mark as externally visible.
194 * dispnew.c (check_window_matrix_pointers): Now static.
195 * dispnew.c (window_to_frame_vpos):
196 * xfns.c (unwind_create_frame):
197 * xterm.c (x_check_font): Remove unused local.
198 * scroll.c (CHECK_BOUNDS):
199 * xfaces.c (cache_fache): Rename local to avoid shadowing.
200 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
201 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
202 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
203 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
204 Now static.
205 (debug_method_add): Use va_list and vsprintf rather than relying
206 on undefined behavior with wrong number of arguments.
207 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
208 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
209 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
210 since we're not interested in debugging glyphs with old libraries.
211 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
212 GCC 4.6.0's static checking.
213
214 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
215

228 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
229 (.bitmaps_last):
230 * xfaces.c (load_pixmap):
231 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
232 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
233 (.bitmaps_last, struct x_output.icon_bitmap):
234 Use ptrdiff_t, not int, for bitmap indexes.
235 (x_allocate_bitmap_record): Check for size overflow.
236 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
237
238 Use ptrdiff_t, not int, for overlay counts.

242 * xdisp.c (next_overlay_change, note_mouse_highlight):
243 * xfaces.c (face_at_buffer_position):
244 * buffer.c (OVERLAY_COUNT_MAX): New macro.

246 (Fnext_overlay_change, Fprevious_overlay_change)
247 (mouse_face_overlay_overlaps, Foverlays_in):
248 Use ptrdiff_t, not int, for sizes.
249 (overlays_at, overlays_in): Check for size-calculation overflow.
250
251 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
252
253 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
254 (x_session_initialize): Do not assume string length fits in int.
255
256 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
257 This is unlikely, but can occur if DPI is outlandish.
258
259 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
260 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

271
272 * xdisp.c (message_log_check_duplicate): Return intmax_t,
273 not unsigned long, as we prefer signed integers. All callers changed.
274 Detect integer overflow in repeat count.
275 (message_dolog): Don't assume print length fits in 39 bytes.
276 (display_mode_element): Don't assume strlen fits in int.
277
278 * termcap.c: Don't assume sizes fit in int and never overflow.
279 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
280 (gobble_line): Check for size-calculation overflow.
281
282 * minibuf.c (Fread_buffer):
283 * lread.c (intern, intern_c_string):
284 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

296
297 * filelock.c: Fix some buffer overrun and integer overflow issues.
298 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
299 Reformulate so as not to need the command string.
300 Invoke gzip -cd rather than gunzip, as it's more portable.
301 (lock_info_type, lock_file_1, lock_file):
302 Don't assume pid_t and time_t fit in unsigned long.
303 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
304 (current_lock_owner): Prefer signed type for sizes.
305 Use memcpy, not strncpy, where memcpy is what is really wanted.
306 Don't assume (via atoi) that time_t and pid_t fit in int.
307 Check for time_t and/or pid_t out of range, e.g., via a network share.
308 Don't alloca where an auto var works fine.
309
310 * fileio.c: Fix some integer overflow issues.
311 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
312 Don't assume string length fits in int.
313 (directory_file_name): Don't assume string length fits in long.

315 length is less than 20.
316
317 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
318
319 * coding.c (make_subsidiaries): Don't assume string length fits in int.
320
321 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
322

334 (Fgetenv_internal):
335 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
336
337 * lread.c (invalid_syntax): Omit length argument.
338 All uses changed. This doesn't fix a bug, but it simplifies the
339 code away from its former Hollerith-constant appearance, and it's
340 one less 'int' to worry about when looking at integer-overflow issues.
341 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
342
343 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
344 This didn't break anything, but it didn't help either.
345 It's confusing to put a bogus integer in a place where the actual
346 value does not matter.
347 (LIST_END_P): Remove unused macro and its bogus comment.
348 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
349
350 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
351 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
352 implementation.
353 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
354 We prefer signed types, and the value cannot exceed the EMACS_INT
355 range anyway (because otherwise the length would not be representable).
356 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
357 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
358 This avoids a GCC warning when WIDE_EMACS_INT.
359
360 * indent.c (sane_tab_width): New function.
361 (current_column, scan_for_column, Findent_to, position_indentation)
362 (compute_motion): Use it. This is just for clarity.
363 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
364
365 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
366
367 * lisp.h (lint_assume): New macro.
368 * composite.c (composition_gstring_put_cache):
369 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
370
371 * editfns.c, insdel.c:
372 Omit unnecessary forward decls, to simplify future changes.
373
374 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
375
376 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
377
378 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
379 Use much-faster test for byte-length change.
380 Don't assume string byte-length fits in 'int'.
381 Check that character arg fits in 'int'.
382 (mapcar1): Declare byte as byte, for clarity.
383
384 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
385
386 * fns.c (concat): Catch string overflow earlier.
387 Do not rely on integer wraparound.
388
389 * dispextern.h (struct it.overlay_strings_charpos)
390 (struct it.selective): Now EMACS_INT, not int.
391 * xdisp.c (forward_to_next_line_start)
392 (back_to_previous_visible_line_start)
393 (reseat_at_next_visible_line_start, next_element_from_buffer):
394 Don't arbitrarily truncate the value of 'selective' to int.
395
396 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
397
398 * composite.c: Don't truncate sizes to 'int'.
399 (composition_gstring_p, composition_reseat_it)
400 (composition_adjust_point): Use EMACS_INT, not int.
401 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
402 not EMACS_UINT, for indexes.
403
404 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
405
406 * buffer.c: Include <verify.h>.
407 (struct sortvec.priority, struct sortstr.priority):
408 Now EMACS_INT, not int.
409 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
410 (struct sortstr.size, record_overlay_string)
411 (struct sortstrlist.size, struct sortlist.used):
412 Don't truncate size to int.
413 (record_overlay_string): Check for size-calculation overflow.
414 (init_buffer_once): Check at compile-time, not run-time.
415
416 2011-06-22 Jim Meyering <meyering@redhat.com>
417
418 Don't leak an XBM-image-sized buffer
419 * image.c (xbm_load): Free the image buffer after using it.
420
421 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
422
423 Port to Sun C.
424 * composite.c (find_automatic_composition): Omit needless 'return 0;'
425 that Sun C diagnosed.
426 * fns.c (secure_hash): Fix pointer signedness issue.
427 * intervals.c (static_offset_intervals): New function.
428 (offset_intervals): Use it.
429
430 2011-06-21 Leo Liu <sdl.web@gmail.com>
431
432 * deps.mk (fns.o):
433 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
434 sha512.h.
435
436 * fns.c (secure_hash): Rename from crypto_hash_function and change
437 the first arg to accept symbols.
438 (Fsecure_hash): New primitive.
439 (syms_of_fns): New symbols.
440
441 2011-06-20 Deniz Dogan <deniz@dogan.se>

444 docstring.
445
446 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
447
448 * dispnew.c (add_window_display_history): Use BVAR.
449
450 * xdisp.c (debug_method_add): Use BVAR.
451 (check_window_end, dump_glyph_matrix, dump_glyph)
452 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
453
454 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
455 Likewise.
456
457 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
458 check till after the cache is created in init_frame_faces.
459
460 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
461
462 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
463
464 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
465
466 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
467 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
468 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
469
470 Improve buffer-overflow checking (Bug#8873).
471 * fileio.c (Finsert_file_contents):
472 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
473 Remove the old (too-loose) buffer overflow checks.
474 They weren't needed, since make_gap checks for buffer overflow.
475 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
476 The old code merely checked for Emacs fixnum overflow, and relied
477 on undefined (wraparound) behavior. The new code avoids undefined
478 behavior, and also checks for ptrdiff_t and/or size_t overflow.
479
480 * editfns.c (Finsert_char): Don't dump core with very negative counts.
481 Tune. Don't use wider integers than needed. Don't use alloca.
482 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
483
484 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
485
486 * insdel.c, lisp.h (buffer_overflow): New function.
487 (insert_from_buffer_1, replace_range, replace_range_2):
488 * insdel.c (make_gap_larger):
489 * editfns.c (Finsert_char):
490 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
491
492 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
493
494 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
495
496 Integer overflow and signedness fixes (Bug#8873).
497
498 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
499 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
500
501 * fileio.c: Don't assume EMACS_INT fits in off_t.
502 (emacs_lseek): New static function.
503 (Finsert_file_contents, Fwrite_region): Use it.
504 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
505
506 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
507
508 * fns.c: Don't overflow int when computing a list length.
509 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
510 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
511 truncation on 64-bit hosts. Check for QUIT every
512 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
513 faster and is responsive enough.
514 (Flength): Report an error instead of overflowing an integer.
515 (Fsafe_length): Return a float if the value is not representable
516 as a fixnum. This shouldn't happen except in contrived situations.
517 (Fnthcdr, Fsort): Don't assume list length fits in int.
518 (Fcopy_sequence): Don't assume vector length fits in int.
519
520 * alloc.c: Check that resized vectors' lengths fit in fixnums.
521 (header_size, word_size): New constants.
522 (allocate_vectorlike): Don't check size overflow here.
523 (allocate_vector): Check it here instead, since this is the only
524 caller of allocate_vectorlike that could cause overflow.
525 Check that the new vector's length is representable as a fixnum.
526
527 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
528 The previous code was bogus. For example, next_almost_prime (32)
529 returned 39, which is undesirable as it is a multiple of 3; and
530 next_almost_prime (24) returned 25, which is a multiple of 5 so
531 why was the code bothering to check for multiples of 7?
532
533 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
534
535 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
536
537 Variadic C functions now count arguments with ptrdiff_t.
538 This partly undoes my 2011-03-30 change, which replaced int with size_t.
539 Back then I didn't know that the Emacs coding style prefers signed int.
540 Also, in the meantime I found a few more instances where arguments
541 were being counted with int, which may truncate counts on 64-bit
542 machines, or EMACS_INT, which may be unnecessarily wide.
543 * lisp.h (struct Lisp_Subr.function.aMANY)
544 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
545 Arg counts are now ptrdiff_t, not size_t.
546 All variadic functions and their callers changed accordingly.
547 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
548 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
549 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
550 * callint.c (Fcall_interactively): Check arg count for overflow,
551 to avoid potential buffer overrun. Use signed char, not 'int',
552 for 'varies' array, so that we needn't bother to check its size
553 calculation for overflow.
554 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
555 * eval.c (apply_lambda):
556 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
557 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
558 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
559
560 * callint.c (Fcall_interactively): Don't use index var as event count.
561
562 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
563 * mem-limits.h (SIZE): Remove; no longer used.
564
565 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
566
567 Remove unnecessary casts.
568 * xterm.c (x_term_init):
569 * xfns.c (x_set_border_pixel):
570 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
571 These aren't needed now that we assume ANSI C.
572
573 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
574 It's more likely to cause problems (due to unsigned overflow)
575 than to cure them.
576
577 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
578
579 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
580
581 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
582
583 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
584
585 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
586
587 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
588
589 GLYPH_CODE_FACE returns EMACS_INT, not int.
590 * dispextern.h (merge_faces):
591 * xfaces.c (merge_faces):
592 * xdisp.c (get_next_display_element, next_element_from_display_vector):
593 Don't assume EMACS_INT fits in int.
594
595 * character.h (CHAR_VALID_P): Remove unused parameter.
596 * fontset.c, lisp.h, xdisp.c: All uses changed.
597
598 * editfns.c (Ftranslate_region_internal): Omit redundant test.
599
600 * fns.c (concat): Minor tuning based on overflow analysis.
601 This doesn't fix any bugs. Use int to hold character, instead
602 of constantly refetching from Emacs object. Use XFASTINT, not
603 XINT, for value known to be a character. Don't bother comparing
604 a single byte to 0400, as it's always less.
605
606 * floatfns.c (Fexpt):
607 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
608
609 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
610 for characters.
611
612 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
613
614 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
615 Without this fix, on a 64-bit host (aset S 0 4294967386) would
616 incorrectly succeed when S was a string, because 4294967386 was
617 truncated before it was used.
618
619 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
620 Otherwise, an out-of-range integer could cause undefined behavior
621 on a 64-bit host.
622
623 * composite.c: Use int, not EMACS_INT, for characters.
624 (fill_gstring_body, composition_compute_stop_pos): Use int, not
625 EMACS_INT, for values that are known to be in character range.
626 This doesn't fix any bugs but is the usual style inside Emacs and
627 may generate better code on 32-bit machines.
628
629 Make sure a 64-bit char is never passed to ENCODE_CHAR.
630 This is for reasons similar to the recent CHAR_STRING fix.
631 * charset.c (Fencode_char): Check that character arg is actually
632 a character. Pass an int to ENCODE_CHAR.
633 * charset.h (ENCODE_CHAR): Verify that the character argument is no
634 wider than 'int', as a compile-time check to prevent future regressions
635 in this area.
636
637 * character.c (char_string): Remove unnecessary casts.
638
639 Make sure a 64-bit char is never passed to CHAR_STRING.
640 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
641 by silently ignoring the top 32 bits, allowing some values
642 that were far too large to be valid characters.
643 * character.h: Include <verify.h>.
644 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
645 arguments are no wider than unsigned, as a compile-time check
646 to prevent future regressions in this area.
647 * data.c (Faset):
648 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
649 (Fsubst_char_in_region):
650 * fns.c (concat):
651 * xdisp.c (decode_mode_spec_coding):
652 Adjust to CHAR_STRING's new requirement.
653 * editfns.c (Finsert_char, Fsubst_char_in_region):
654 * fns.c (concat): Check that character args are actually
655 characters. Without this test, these functions did the wrong
656 thing with wildly out-of-range values on 64-bit hosts.
657
658 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
659 These casts should not be needed on 32-bit hosts, either.
660 * keyboard.c (read_char):
661 * lread.c (Fload): Remove casts to unsigned.
662
663 * lisp.h (UNSIGNED_CMP): New macro.
664 This fixes comparison bugs on 64-bit hosts.
665 (ASCII_CHAR_P): Use it.
666 * casefiddle.c (casify_object):
667 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
668 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
669 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
670 * dispextern.h (FACE_FROM_ID):
671 * keyboard.c (read_char): Use UNSIGNED_CMP.
672
673 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
674 not to EMACS_INT, to avoid GCC warning.
675
676 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
677
678 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
679 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
680 isn't needed on 32-bit machines.
681
682 * buffer.c (Fgenerate_new_buffer_name):
683 Use EMACS_INT for count, not int.
684 (advance_to_char_boundary): Return EMACS_INT, not int.
685
686 * data.c (Qcompiled_function): Now static.
687
688 * window.c (window_body_lines): Now static.
689
690 * image.c (gif_load): Rename local to avoid shadowing.
691
692 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
693 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
694 * alloc.c (make_save_value): Integer argument is now of type
695 ptrdiff_t, not int.
696 (mark_object): Use ptrdiff_t, not int.
697 * lisp.h (pD): New macro.
698 * print.c (print_object): Use it.
699
700 * alloc.c: Use EMACS_INT, not int, to count objects.
701 (total_conses, total_markers, total_symbols, total_vector_size)
702 (total_free_conses, total_free_markers, total_free_symbols)
703 (total_free_floats, total_floats, total_free_intervals)
704 (total_intervals, total_strings, total_free_strings):
705 Now EMACS_INT, not int. All uses changed.
706 (Fgarbage_collect): Compute overall total using a double, so that
707 integer overflow is less likely to be a problem. Check for overflow
708 when converting back to an integer.
709 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
710 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
711 These were 'int' variables that could overflow on 64-bit hosts;
712 they were never used, so remove them instead of repairing them.
713 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
714 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
715 Previously, this ceilinged at INT_MAX, but that doesn't work on
716 64-bit machines.
717 (allocate_pseudovector): Don't use EMACS_INT when int would do.
718
719 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
720 (allocate_vectorlike): Check for ptrdiff_t overflow.
721 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
722 when a (possibly-narrower) signed value would do just as well.
723 We prefer using signed arithmetic, to avoid comparison confusion.
724
725 * alloc.c: Catch some string size overflows that we were missing.
726 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
727 for convenience in STRING_BYTES_MAX.
728 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
729 The definition here is exact; the one in lisp.h was approximate.
730 (allocate_string_data): Check for string overflow. This catches
731 some instances we weren't catching before. Also, it catches
732 size_t overflow on (unusual) hosts where SIZE_MAX <= min
733 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
734 and ptrdiff_t and EMACS_INT are both 64 bits.
735
736 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
737 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
738 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
739
740 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
741
742 * alloc.c (Fmake_string): Check for out-of-range init.
743
744 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
745
746 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
747
748 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
749
750 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
751 xg_get_default_scrollbar_width.
752
753 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
754 (int_gtk_range_get_value): Move to the scroll bar part of the file.
755 (style_changed_cb): Call update_theme_scrollbar_width and call
756 x_set_scroll_bar_default_width and xg_frame_set_char_size for
757 all frames (Bug#8505).
758 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
759 Call gtk_window_set_resizable if HAVE_GTK3.
760 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
761 and height if HAVE_GTK3 (Bug#8505).
762 (scroll_bar_width_for_theme): New variable.
763 (update_theme_scrollbar_width): New function.
764 (xg_get_default_scrollbar_width): Move code to
765 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
766 (xg_initialize): Call update_theme_scrollbar_width.
767
768 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
769
770 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
771
772 2011-06-12 Martin Rudalics <rudalics@gmx.at>
773
774 * frame.c (make_frame): Call other_buffer_safely instead of
775 other_buffer.
776
777 * window.c (temp_output_buffer_show): Call display_buffer with
778 second argument Vtemp_buffer_show_specifiers and reset latter
779 immediately after the call.
780 (Vtemp_buffer_show_specifiers): New variable.
781 (auto_window_vscroll_p, next_screen_context_lines)
782 (Vscroll_preserve_screen_position): Remove leading asterisks from
783 doc-strings.
784
785 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
786
787 Fix minor problems found by GCC 4.6.0 static checking.
788 * buffer.c (Qclone_number): Remove for now, as it's unused.
789 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
790 (record_buffer): Remove unused local.
791 * frame.c (other_visible_frames, frame_buffer_list): Now static.
792 (set_frame_buffer_list): Remove; unused.
793 * frame.h (other_visible_frames): Remove decl.
794 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
795 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
796 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
797 if HAVE_GPM.
798 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
799 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
800 Define only if HAVE_GPM.
801 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
802 (update_hints_inhibit): Remove; never set. All uses removed.
803 * widgetprv.h (emacsFrameClassRec): Remove decl.
804 * window.c (delete_deletable_window): Now returns void, since it
805 wasn't returning anything.
806 (compare_window_configurations): Remove unused locals.
807 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
808 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
809 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
810 the same widths as pointers. This follows up on the 2011-05-06 patch.
811 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
812 * xterm.h: Likewise.
813 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
814
815 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
816
817 * makefile.w32-in: Update dependencies.
818 (LISP_H): Add lib/intprops.h.
819
820 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
821
822 * image.c (gif_load): Add animation frame delay to the metadata.
823 (syms_of_image): Use DEFSYM. New symbol `delay'.
824
825 2011-06-11 Martin Rudalics <rudalics@gmx.at>
826
827 * window.c (delete_deletable_window): Re-add.
828 (Fset_window_configuration): Rewrite to handle dead buffers and
829 consequently deletable windows.
830 (window_tree, Fwindow_tree): Remove. Supply functionality in
831 window.el.
832 (compare_window_configurations): Simplify code.
833
834 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
835
836 * image.c (imagemagick_load_image): Fix type mismatch.
837 (Fimagemagick_types): Likewise.
838
839 * window.h (replace_buffer_in_windows): Declare.
840
841 2011-06-11 Martin Rudalics <rudalics@gmx.at>
842
843 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
844 Qclone_number. Remove external declaration of Qdelete_window.
845 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
846 code.
847 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer): Run
848 Qbuffer_list_update_hook if allowed.
849 (Fother_buffer): Rewrite doc-string. Major rewrite for new
850 buffer list implementation.
851 (other_buffer_safely): New function.
852 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
853 calls to replace_buffer_in_windows and
854 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
855 if allowed.
856 (record_buffer): Inhibit quitting and rewrite using quittable
857 functions. Run Qbuffer_list_update_hook if allowed.
858 (Frecord_buffer, Funrecord_buffer): New functions.
859 (switch_to_buffer_1, Fswitch_to_buffer): Remove. Move
860 switch-to-buffer to window.el.
861 (bury-buffer): Move to window.el.
862 (Vbuffer_list_update_hook): New variable.
863
864 * lisp.h (other_buffer_safely): Add prototype in buffer.c
865 section.
866
867 * window.h (resize_frame_windows): Move up in code.
868 (Fwindow_frame): Remove EXFUN.
869 (replace_buffer_in_all_windows): Remove prototype.
870 (replace_buffer_in_windows_safely): Add prototype.
871
872 * window.c: Declare Qdelete_window static again. Move down
873 declaration of select_count.
874 (Fnext_window, Fprevious_window): Rewrite doc-strings.
875 (Fother_window): Move to window.el.

1306 display string.
1307 (bidi_paragraph_init, bidi_resolve_explicit_1)
1308 (bidi_level_of_next_char): Call bidi_fetch_char and
1309 bidi_fetch_char_advance instead of FETCH_CHAR and
1310 FETCH_CHAR_ADVANCE.
1311 (bidi_init_it): Initialize new members.
1312 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
1313 definitions.
1314 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
1315 instead of using explicit *_CHAR codes.
1316 (bidi_resolve_explicit, bidi_resolve_weak):
1317 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
1318 bidirectional text is supported only in multibyte buffers.
1319 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
1320 it to initialize the frame_window_p member of struct bidi_it.
1321 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
1322 (bidi_resolve_explicit, bidi_resolve_weak)
1323 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
1324 bidi_it->nchars is non-positive.
1325 (bidi_level_of_next_char): Don't try to lookup the cache for the
1326 next/previous character if nothing is cached there yet, or if we
1327 were just reseat()'ed to a new position.
1328
1329 * xdisp.c (set_cursor_from_row): Set start and stop points
1330 according to the row's direction when priming the loop that looks
1331 for the glyph on which to display cursor.
1332 (single_display_spec_intangible_p): Function deleted.
1333 (display_prop_intangible_p): Reimplement to call
1334 handle_display_spec instead of single_display_spec_intangible_p.
1335 Accept 3 additional arguments needed by handle_display_spec.
1336 This fixes incorrect cursor motion across display property with complex
1337 values: lists, `(when COND...)' forms, etc.
1338 (single_display_spec_string_p): Support property values that are
1339 lists with the argument STRING its top-level element.
1340 (display_prop_string_p): Fix the condition for processing a
1341 property that is a list to be consistent with handle_display_spec.
1342 (handle_display_spec): New function, refactored from the
1343 last portion of handle_display_prop.
1344 (compute_display_string_pos): Accept additional argument
1345 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
1346 value of a `display' property is a "replacing spec".
1347 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
1348 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
1349 the display property, but just return a value indicating whether
1350 the display property will replace the characters it covers.
1351 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
1352 frame_window_p members of struct bidi_it.
1353 (compute_display_string_pos, compute_display_string_end):
1354 New functions.
1355 (push_it): Accept second argument POSITION, where pop_it should
1356 jump to continue iteration.
1357 (reseat_1): Initialize bidi_it.disp_pos.
1358
1359 * keyboard.c (adjust_point_for_property): Adjust the call to
1360 display_prop_intangible_p to its new signature.
1361
1362 * dispextern.h (struct bidi_it): New member frame_window_p.
1363 (bidi_init_it): Update prototypes.
1364 (display_prop_intangible_p): Update prototype.
1365 (compute_display_string_pos, compute_display_string_end):
1366 Declare prototypes.
1367 (struct bidi_it): New members nchars and disp_pos. ch_len is now
1368 EMACS_INT.
1369
1370 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
1371
1372 Malloc failure behavior now depends on size of allocation.

1374 * lisp.h: Change signatures accordingly.
1375 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
1376 All callers changed. (Bug#8762)
1377
1378 * gnutls.c: Use Emacs's memory allocators.
1379 Without this change, the gnutls library would invoke malloc etc.
1380 directly, which causes problems on non-SYNC_INPUT hosts, and which
1381 runs afoul of improving memory_full behavior. (Bug#8761)
1382 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
1383 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
1384 xfree instead of the default malloc, realloc, free.
1385 (Fgnutls_boot): No need to check for memory allocation failure,
1386 since xmalloc does that for us.
1387
1388 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
1389 * category.c (hash_get_category_set):
1390 * ccl.c (ccl_driver):
1391 * charset.c (Fdefine_charset_internal):
1392 * charset.h (struct charset.hash_index):
1393 * composite.c (get_composition_id, gstring_lookup_cache)
1394 (composition_gstring_put_cache):
1395 * composite.h (struct composition.hash_index):
1396 * dispextern.h (struct image.hash):
1397 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
1398 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
1399 (hashfn_equal, hashfn_user_defined, make_hash_table)
1400 (maybe_resize_hash_table, hash_lookup, hash_put)
1401 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
1402 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
1403 (Fsxhash, Fgethash, Fputhash, Fmaphash):
1404 * image.c (make_image, search_image_cache, lookup_image)
1405 (xpm_put_color_table_h):
1406 * lisp.h (struct Lisp_Hash_Table):
1407 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
1408 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
1409 for hashes and hash indexes, instead of 'unsigned' and 'int'.
1410 * alloc.c (allocate_vectorlike):
1411 Check for overflow in vector size calculations.
1412 * ccl.c (ccl_driver):
1413 Check for overflow when converting EMACS_INT to int.
1414 * fns.c, image.c: Remove unnecessary static decls that would otherwise
1415 need to be updated by these changes.
1416 * fns.c (make_hash_table, maybe_resize_hash_table):
1417 Check for integer overflow with large hash tables.
1418 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
1419 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1420 (SXHASH_REDUCE): New macro.
1421 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1422 Use it instead of discarding useful hash info with large hash values.
1423 (sxhash_float): New function.
1424 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1425 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1426 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1427 Rewrite to use FIXNUM_BITS, as this simplifies things.
1428 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1429 Adjust signatures to match updated version of code.
1430 (consing_since_gc): Now EMACS_INT, since a single hash table can
1431 use more than INT_MAX bytes.
1432
1433 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1434
1435 Make it possible to build with GCC-4.6+ -O2 -flto.
1436
1437 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
1438
1439 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1440
1441 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1442 Call minibuffer-inactive-mode.
1443
1444 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1445
1446 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1447 Update dependencies.
1448
1449 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1450
1451 * data.c (init_data): Remove code for UTS, this system is not
1452 supported anymore.
1453
1454 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1455
1456 Don't force ./temacs to start in terminal mode.
1457
1458 * frame.c (make_initial_frame): Initialize faces in all cases, not
1459 only when CANNOT_DUMP is defined.
1460 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1461
1462 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1463
1464 * dispnew.c (add_window_display_history): Use const for the string
1465 pointer. Remove declaration, not needed.
1466
1467 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1468
1469 Use 'inline', not 'INLINE'.
1470 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1471 * alloc.c, fontset.c (INLINE): Remove.
1472 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1473 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1474 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1475 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1476 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1477
1478 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1479
1480 Make it possible to run ./temacs.
1481
1482 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1483 syms_of_callproc does the same thing. Remove test for
1484 "initialized", do it in the caller.
1485 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1486
1487 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1488
1489 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1490 (read_minibuf): Use get_minibuffer.
1491 (syms_of_minibuf): Use DEFSYM.
1492 (Qmetadata): New var.
1493 * data.c (Qbuffer): Don't make it static.
1494 (syms_of_data): Use DEFSYM.
1495
1496 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1497
1498 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1499 (CCL_CODE_MIN): New macro.
1500
1501 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1502
1503 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1504
1505 * eval.c (Qdebug): Now static.
1506 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1507 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1508 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1509
1510 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1511
1512 * image.c: Various fixes to ImageMagick code comments.
1513 (Fimagemagick_types): Doc fix.
1514
1515 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1516
1517 Minor fixes prompted by GCC 4.6.0 warnings.
1518
1519 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1520
1521 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1522 (x_clipboard_manager_save_all): Move extern decl to ...
1523 * xterm.h: ... here, so that it can be checked for consistency.
1524
1525 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1526
1527 * xselect.c (x_clipboard_manager_save_frame)
1528 (x_clipboard_manager_save_all): New functions.
1529 (Fx_clipboard_manager_save): Lisp function deleted.
1530
1531 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1532 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1533
1534 * xterm.h: Update prototype.
1535
1536 2011-05-28 William Xu <william.xwl@gmail.com>
1537
1538 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1539 exiting (Bug#8239).
1540
1541 2011-05-28 Jim Meyering <meyering@redhat.com>
1542
1543 Avoid a sign-extension bug in crypto_hash_function.
1544 * fns.c (to_uchar): Define.
1545 (crypto_hash_function): Use it to convert some newly-signed
1546 variables to unsigned, to avoid sign-extension bugs. For example,
1547 without this change, (md5 "truc") would evaluate to
1548 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1549 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1550 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1551
1552 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1553
1554 Integer overflow fixes.
1555
1556 * dbusbind.c: Serial number integer overflow fixes.
1557 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1558 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1559 to hold a serial number that is too large for a fixnum.
1560 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1561 Check for serial numbers out of range. Decode any serial number
1562 that was so large that it became a float. (Bug#8722)
1563
1564 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1565 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1566 Use XFASTINT rather than XUINT when numbers are nonnegative.
1567 (xd_append_arg, Fdbus_method_return_internal):
1568 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1569 arguments, check that Lisp number is nonnegative, rather than
1570 silently wrapping negative numbers around. (Bug#8722)
1571 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1572 (Bug#8722)
1573
1574 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1575
1576 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1577
1578 ccl: add integer overflow checks
1579 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1580 (IN_INT_RANGE): New macros.
1581 (ccl_driver): Use them to check for integer overflow when
1582 decoding a CCL program. Many of the new checks are whether XINT (x)
1583 fits in int; it doesn't always, on 64-bit hosts. The new version
1584 doesn't catch all possible integer overflows, but it's an
1585 improvement. (Bug#8719)
1586
1587 * alloc.c (make_event_array): Use XINT, not XUINT.
1588 There's no need for unsigned here.
1589
1590 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1591 This follows up to the 2011-05-06 change that substituted uintptr_t
1592 for EMACS_INT. This case wasn't caught back then.
1593
1594 Rework Fformat to avoid integer overflow issues.
1595 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1596 now (part of C89). Include <verify.h>.
1597 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1598 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1599 (Fformat): Avoid the prepass trying to compute sizes; it was only
1600 approximate and thus did not catch overflow reliably. Instead, walk
1601 through the format just once, formatting and computing sizes as we go,
1602 checking for integer overflow at every step, and allocating a larger
1603 buffer as needed. Keep track separately whether the format is
1604 multibyte. Keep only the most-recently calculated precision, rather
1605 than them all. Record whether each argument has been converted to
1606 string. Use EMACS_INT, not int, for byte and char and arg counts.
1607 Support field widths and precisions larger than INT_MAX. Avoid
1608 sprintf's undefined behavior with conversion specifications such as %#d
1609 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1610 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1611 formatting out-of-range floating point numbers with int
1612 formats. (Bug#8668)
1613
1614 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1615
1616 * data.c: Avoid integer truncation in expressions involving floats.
1617 * data.c: Include <intprops.h>.
1618 (arith_driver): When there's an integer overflow in an expression
1619 involving floating point, convert the integers to floating point
1620 so that the resulting value does not suffer from catastrophic
1621 integer truncation. For example, on a 64-bit host (* 4
1622 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1623 Do not rely on undefined behavior after integer overflow.
1624
1625 merge count_size_as_multibyte, parse_str_to_multibyte
1626 * character.c, character.h (count_size_as_multibyte):
1627 Rename from parse_str_to_multibyte; all uses changed.
1628 Check for integer overflow.
1629 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1630 since it's now a duplicate of the other. This is more of
1631 a character than a buffer op, so better that it's in character.c.
1632 * fns.c, print.c: Adjust to above changes.
1633
1634 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1635
1636 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1637
1638 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1639
1640 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1641 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1642 (x_clipboard_manager_save): Now static.
1643 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1644
1645 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1646 (crypto_hash_function): Now static.
1647 Fix pointer signedness problems. Avoid unnecessary initializations.
1648
1649 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1650
1651 * termhooks.h (Vselection_alist): Make it terminal-local.
1652
1653 * terminal.c (create_terminal): Initialize it.
1654
1655 * xselect.c: Support for clipboard managers.
1656 (Vselection_alist): Move to termhooks.h as terminal-local var.
1657 (LOCAL_SELECTION): New macro.
1658 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1659 (symbol_to_x_atom): Remove gratuitous arg.
1660 (x_handle_selection_request, lisp_data_to_selection_data)
1661 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1662 (x_own_selection, x_get_local_selection, x_convert_selection):
1663 New arg, specifying work frame. Use terminal-local Vselection_alist.
1664 (some_frame_on_display): Delete unused function.
1665 (Fx_own_selection_internal, Fx_get_selection_internal)
1666 (Fx_disown_selection_internal, Fx_selection_owner_p)
1667 (Fx_selection_exists_p): New optional frame arg.
1668 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1669 (x_handle_selection_clear): Don't treat other terminals with the
1670 same keyboard specially. Use the terminal-local Vselection_alist.
1671 (x_clear_frame_selections): Use Frun_hook_with_args.
1672
1673 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1674
1675 * xterm.h: Add support for those atoms.
1676
1677 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1678
1679 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1680 (converted_selections, conversion_fail_tag): New global variables.
1681 (x_selection_request_lisp_error): Free the above.
1682 (x_get_local_selection): Remove unnecessary code.
1683 (x_reply_selection_request): Args changed; handle arbitrary array
1684 of converted selections stored in converted_selections.
1685 Separate the XChangeProperty and SelectionNotify steps.
1686 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1687 (x_convert_selection): New function.
1688 (x_handle_selection_event): Simplify.
1689 (x_get_foreign_selection): Don't ignore incoming requests while
1690 waiting for an answer; this will fail when we implement
1691 SAVE_TARGETS, and seems unnecessary anyway.
1692 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1693 (Vx_sent_selection_functions): Doc fix.
1694
1695 2011-05-26 Leo Liu <sdl.web@gmail.com>
1696
1697 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)

1700
1701 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1702
1703 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1704 for fringe update if it has periodic bitmap.
1705 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1706 and fringe_bitmap_periodic_p.
1707
1708 * fringe.c (get_fringe_bitmap_data): New function.
1709 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1710 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1711 row. Mark glyph row for fringe update if periodicity changed.
1712
1713 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1714 for fringe update unless it has periodic bitmap.
1715
1716 2011-05-25 Kenichi Handa <handa@m17n.org>
1717
1718 * xdisp.c (get_next_display_element): Set correct it->face_id for
1719 a static composition.
1720
1721 2011-05-24 Leo Liu <sdl.web@gmail.com>
1722
1723 * deps.mk (fns.o):
1724 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
1725
1726 * fns.c (crypto_hash_function, Fsha1): New function.
1727 (Fmd5): Use crypto_hash_function.
1728 (syms_of_fns): Add Ssha1.
1729
1730 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1731
1732 * gnutls.c: Remove unused macros.
1733 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
1734 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1735 Remove macros that are defined and never used.
1736 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1737
1738 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1739
1740 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1741 (Fx_get_selection_internal): Minor cleanup.
1742 (Fx_own_selection_internal): Rename arguments for consistency with
1743 select.el.
1744
1745 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1746
1747 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
1748
1749 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1750
1751 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
1752
1753 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1754
1755 * dispnew.c (scrolling_window): Don't exclude the case that the
1756 last enabled row in the desired matrix touches the bottom boundary.
1757
1758 2011-05-21 Glenn Morris <rgm@gnu.org>
1759
1760 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1761 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1762 and add some more files.
1763
1764 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1765
1766 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1767 report_file_error introduced by the change from 2011-05-07.
1768
1769 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1770
1771 * systime.h (Time): Define only if emacs is defined.
1772 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1773 where the include path doesn't have X11/X.h by default. See
1774 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1775
1776 2011-05-20 Kenichi Handa <handa@m17n.org>
1777
1778 * composite.c (find_automatic_composition): Fix previous change.
1779
1780 2011-05-20 Glenn Morris <rgm@gnu.org>
1781
1782 * lisp.mk: New file, split from Makefile.in.
1783 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1784 (shortlisp): Remove.
1785 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1786
1787 2011-05-19 Glenn Morris <rgm@gnu.org>
1788
1789 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1790 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1791 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1792 (lisp): Set the order to that of loadup.el.
1793 (shortlisp): Make it a copy of $lisp.
1794 (SOME_MACHINE_LISP): Remove.
1795 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1796 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1797
1798 2011-05-18 Kenichi Handa <handa@m17n.org>
1799
1800 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1801 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1802 (find_automatic_composition): Mostly rewrite for efficiency.
1803
1804 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1805
1806 * makefile.w32-in: Update dependencies.
1807
1808 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1809
1810 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1811 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1812
1813 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1814
1815 Fix some integer overflow issues, such as string length overflow.
1816
1817 * insdel.c (count_size_as_multibyte): Check for string overflow.
1818
1819 * character.c (lisp_string_width): Check for string overflow.
1820 Use EMACS_INT, not int, for string indexes and lengths; in
1821 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1822 the resulting string length overflows an EMACS_INT; instead,
1823 report a string overflow if no precision given. When checking for
1824 precision exhaustion, use a check that cannot possibly have
1825 integer overflow. (Bug#8675)
1826 * character.h (lisp_string_width): Adjust to new signature.
1827
1828 * alloc.c (string_overflow): New function.
1829 (Fmake_string): Use it. This doesn't change behavior, but saves
1830 a few bytes and will simplify future changes.
1831 * character.c (string_escape_byte8): Likewise.
1832 * lisp.h (string_overflow): New decl.
1833
1834 Fixups, following up to the user-interface timestamp change.
1835 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1836 for UI timestamps, instead of unsigned long.
1837 * msdos.c (mouse_get_pos): Likewise.
1838 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1839 * w32gui.h (Time): Define by including "systime.h" rather than by
1840 declaring it ourselves. (Bug#8664)
1841
1842 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1843 * image.c (clear_image_cache): Likewise.
1844
1845 * term.c (term_mouse_position): Don't assume time_t wraparound.
1846
1847 Be more systematic about user-interface timestamps.
1848 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1849 and sometimes 'EMACS_UINT', to represent these timestamps.
1850 This change causes it to use 'Time' uniformly, as that's what X uses.
1851 This makes the code easier to follow, and makes it easier to catch
1852 integer overflow bugs such as Bug#8664.
1853 * frame.c (Fmouse_position, Fmouse_pixel_position):
1854 Use Time, not unsigned long, for user-interface timestamps.
1855 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1856 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1857 * keyboard.h (last_event_timestamp): Likewise.
1858 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1859 * menu.h (xmenu_show): Likewise.
1860 * term.c (term_mouse_position): Likewise.
1861 * termhooks.h (struct input_event.timestamp): Likewise.
1862 (struct terminal.mouse_position_hook): Likewise.
1863 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1864 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1865 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1866 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1867 what it was before.
1868 * menu.h, termhooks.h: Include "systime.h", for Time.
1869
1870 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1871 Don't assume that the difference between two unsigned long values
1872 can fit into an integer. At this point, we know button_down_time
1873 <= event->timestamp, so the difference must be nonnegative, so
1874 there's no need to cast the result if double-click-time is
1875 nonnegative, as it should be; check that it's nonnegative, just in
1876 case. This bug is triggered when events are more than 2**31 ms
1877 apart (about 25 days). (Bug#8664)
1878
1879 * xselect.c (last_event_timestamp): Remove duplicate decl.
1880 (x_own_selection): Remove needless cast to unsigned long.
1881
1882 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1883 that always fit in int. Use a sentinel instead of a counter, to
1884 avoid a temp and to allay GCC's concerns about possible int overflow.
1885 * frame.h (struct frame): Use int for menu_bar_items_used
1886 instead of EMACS_INT, since it always fits in int.
1887
1888 * menu.c (grow_menu_items): Check for int overflow.
1889
1890 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1891
1892 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1893 Before, the code was not consistent. These values cannot exceed
1894 2**31 - 1 so there's no need to make them unsigned.
1895 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1896 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1897 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1898 as modifiers.
1899 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1900
1901 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1902 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1903 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1904 presumably because the widths might not match.
1905
1906 * window.c (size_window): Avoid needless test at loop start.
1907
1908 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1909
1910 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1911
1912 2011-05-12 Drew Adams <drew.adams@oracle.com>
1913
1914 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1915
1916 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1917
1918 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1919 `width' to `bar_area_x' and `bar_area_width', respectively.
1920 (x_scroll_run): Take account of fringe background extension.
1921
1922 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1923 Rename local vars `left' and `width' to `bar_area_x' and
1924 `bar_area_width', respectively.
1925 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1926 background extension.
1927
1928 2011-05-10 Jim Meyering <meyering@redhat.com>
1929
1930 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1931
1932 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1933
1934 * image.c (Finit_image_library): Return t for built-in image types,
1935 like pbm and xbm. (Bug#8640)
1936
1937 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1938
1939 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1940
1941 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1942
1943 * w32console.c (Fset_screen_color): Doc fix.
1944 (Fget_screen_color): New function.
1945 (syms_of_ntterm): Defsubr it.
1946
1947 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1948 unlink the temporary file if Fcall_process didn't create it in the
1949 first place.
1950 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1951 child process will be redirected to a file specified with `:file'.
1952 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1953 cue to call_process_cleanup not to close that handle.
1954
1955 2011-05-07 Ben Key <bkey76@gmail.com>
1956
1957 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1958 one of two shell specific rules, either bootstrap-temacs-CMD or
1959 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1960 to the previous implementation of the bootstrap-temacs rule.
1961 The bootstrap-temacs-CMD rule is similar to the previous
1962 implementation of the bootstrap-temacs rule except that it
1963 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1964 variable.
1965
1966 These changes, along with some changes to nt/configure.bat,
1967 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1968 earlier fix to add support for --cflags and --ldflags options
1969 that include quotes so that it works whether make uses cmd or
1970 sh as the shell.
1971
1972 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1973
1974 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1975 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1976 is a constant.
1977 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1978 a string. Handle both cases.
1979 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1980 (Fdbus_register_method): Use Qinvalid_function.
1981
1982 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1983
1984 * makefile.w32-in: Update dependencies.
1985 (LISP_H): Add inttypes.h and stdin.h.
1986 (PROCESS_H): Add unistd.h.
1987
1988 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1989
1990 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1991 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1992
1993 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1994
1995 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1996
1997 * term.c (vfatal): Remove stray call to va_end.
1998 It's not needed and the C Standard doesn't allow it here anyway.
1999
2000 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
2001 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
2002
2003 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
2004 bytes.
2005
2006 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
2007
2008 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2009
2010 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
2011
2012 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
2013
2014 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
2015
2016 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
2017 * charset.c (Fdefine_charset_internal): Don't initialize
2018 charset.code_space[15]. The value was garbage, on hosts with
2019 32-bit int (Bug#8600).
2020
2021 * lread.c (read_integer): Be more consistent with string-to-number.
2022 Use string_to_number to do the actual conversion; this avoids
2023 rounding errors and fixes some other screwups. Without this fix,
2024 for example, #x1fffffffffffffff was misread as -2305843009213693952.
2025 (digit_to_number): Move earlier, for benefit of read_integer.
2026 Return -1 if the digit is out of range for the base, -2 if it is
2027 not a digit in any supported base. (Bug#8602)
2028
2029 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
2030
2031 * dispnew.c (scrolling_window): Return 1 if we scrolled,
2032 to match comment at start of function. This also removes a
2033 GCC warning about overflow in a 32+64-bit port.
2034
2035 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
2036
2037 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
2038 Reported by Stefan Monnier in
2039 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
2040 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2041 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
2042
2043 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
2044 (EMACS_UINTPTR): Likewise, with uintptr_t.
2045
2046 * lisp.h: Prefer 64-bit EMACS_INT if available.
2047 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
2048 on 32-bit hosts that have 64-bit int, so that they can access
2049 large files.
2050 However, temporarily disable this change unless the temporary
2051 symbol WIDE_EMACS_INT is defined.
2052
2053 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
2054
2055 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
2056 This removes an assumption that EMACS_INT and long are the same
2057 width as pointers. The assumption is true for Emacs porting targets
2058 now, but we want to make other targets possible.
2059 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
2060 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
2061 In the rest of the code, change types of integers that hold casted
2062 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
2063 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
2064 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
2065 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
2066 No need to cast type when ORing.
2067 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
2068 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
2069 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
2070 assume EMACS_INT is the same width as char *.
2071 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
2072 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
2073 Remove no-longer-needed casts.
2074 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
2075 (xg_tool_bar_help_callback, xg_make_tool_item):
2076 Use EMACS_INTPTR to hold an integer
2077 that will be cast to void *; this can avoid a GCC warning
2078 if EMACS_INT is not the same width as void *.
2079 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
2080 * xdisp.c (display_echo_area_1, resize_mini_window_1):
2081 (current_message_1, set_message_1):
2082 Use a local to convert to proper width without a cast.
2083 * xmenu.c (dialog_selection_callback): Likewise.
2084
2085 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
2086 Also, don't assume VALBITS / RAND_BITS is less than 5,
2087 and don't rely on undefined behavior when shifting a 1 left into
2088 the sign bit.
2089 * lisp.h (get_random): Change signature to match.
2090
2091 * lread.c (hash_string): Use size_t, not int, for hash computation.
2092 Normally we prefer signed values; but hashing is special, because
2093 it's better to use unsigned division on hash table sizes so that
2094 the remainder is nonnegative. Also, size_t is the natural width
2095 for hashing into memory. The previous code used 'int', which doesn't
2096 retain enough info to hash well into very large tables.
2097 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
2098
2099 * dbusbind.c: Don't possibly lose pointer info when converting.
2100 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2101 Use XPNTR rather than XHASH, so that the high-order bits of
2102 the pointer aren't lost when converting through void *.
2103
2104 * eval.c (Fautoload): Don't double-shift a pointer.
2105
2106 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
2107
2108 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2109
2110 * gnutls.c (DEF_GNUTLS_FN):

2243 rather than `XVECTOR (FOO)->size'.
2244
2245 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
2246 inttypes.h, as a gnulib replacement is used if it not available in

2271 simple variables to record original value of point. (Bug#7952)
2272
2273 * doprnt.c (doprnt): Fix the case where a multibyte sequence
2274 produced by %s or %c overflows available buffer space. (Bug#8545)
2275
2276 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
2277
2278 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

2284
2285 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2286

2288 (command_loop_1): Run `delayed-warnings-hook'
2289 if Vdelayed_warnings_list is non-nil.
2290 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
2291 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
2292
2293 2011-04-28 Eli Zaretskii <eliz@gnu.org>
2294
2295 * doprnt.c (doprnt): Don't return value smaller than the buffer
2296 size if the message was truncated. (Bug#8545).
2297
2298 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2299

2311 2011-04-27 Eli Zaretskii <eliz@gnu.org>
2312
2313 Improve `doprnt' and its usage. (Bug#8545)
2314 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
2315 `format_end'. Remove support for %l as a conversion specifier.
2316 Don't use xrealloc. Improve diagnostics when the %l size modifier
2317 is used. Update the commentary.
2318
2319 * eval.c (verror): Simplify calculation of size_t.
2320
2321 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
2322 messages.
2323
2324 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
2325
2326 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
2327 change.
2328
2329 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2330
2331 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
2332 This makes this file independent of the recent pseudovector change.
2333
2334 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
2335
2336 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
2337
2338 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
2339 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
2340 Remove unused local.
2341 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
2342
2343 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
2344 GCC 4.6.0 optimizes based on type-based alias analysis.
2345 For example, if b is of type struct buffer * and v of type struct
2346 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
2347 != &v->size, and therefore "v->size = 1; b->size = 2; return
2348 v->size;" must therefore return 1. This assumption is incorrect
2349 for Emacs, since it type-puns struct Lisp_Vector * with many other
2350 types. To fix this problem, this patch adds a new type struct
2351 vectorlike_header that documents the constraints on layout of vectors
2352 and pseudovectors, and helps optimizing compilers not get fooled
2353 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
2354 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
2355 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
2356 the size member.
2357 (XSETPVECTYPE): Rewrite in terms of new macro.
2358 (XSETPVECTYPESIZE): New macro, specifying both type and size.
2359 This is a bit clearer, and further avoids the possibility of
2360 undesirable aliasing.
2361 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
2362 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
2363 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
2364 since Lisp_Subr is a special case (no "next" field).
2365 (ASIZE): Now uses header.size rather than size.
2366 All previous uses of XVECTOR (foo)->size replaced to use this macro,
2367 to avoid the hassle of writing XVECTOR (foo)->header.size.
2368 (struct vectorlike_header): New type.
2369 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
2370 object, to help avoid aliasing.
2371 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
2372 (SUBRP): Likewise, since Lisp_Subr is a special case.
2373 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
2374 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
2375 (struct Lisp_Hash_Table): Combine first two members into a single
2376 struct vectorlike_header member. All uses of "size" and "next" members
2377 changed to be "header.size" and "header.next".
2378 * buffer.h (struct buffer): Likewise.
2379 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
2380 * frame.h (struct frame): Likewise.
2381 * process.h (struct Lisp_Process): Likewise.
2382 * termhooks.h (struct terminal): Likewise.
2383 * window.c (struct save_window_data, struct saved_window): Likewise.
2384 * window.h (struct window): Likewise.
2385 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2386 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2387 * buffer.c (init_buffer_once): Likewise.
2388 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2389 special case.
2390 * process.c (Fformat_network_address): Use local var for size,
2391 for brevity.
2392
2393 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2394
2395 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2396 * data.c (atof): Remove decl; no longer used or needed.
2397 (digit_to_number): Move to lread.c.
2398 (Fstring_to_number): Use new string_to_number function, to be
2399 consistent with how the Lisp reader treats infinities and NaNs.
2400 Do not assume that floating-point numbers represent EMACS_INT
2401 without losing information; this is not true on most 64-bit hosts.
2402 Avoid double-rounding errors, by insisting on integers when
2403 parsing non-base-10 numbers, as the documentation specifies.
2404 * lisp.h (string_to_number): New decl, replacing ...
2405 (isfloat_string): Remove.
2406 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2407 (read1): Do not accept +. and -. as integers; this
2408 appears to have been a coding error. Similarly, do not accept
2409 strings like +-1e0 as floating point numbers. Do not report
2410 overflow for integer overflows unless the base is not 10 which
2411 means we have no simple and reliable way to continue.
2412 Break out the floating-point parsing into a new
2413 function string_to_number, so that Fstring_to_number parses
2414 floating point numbers consistently with the Lisp reader.
2415 (digit_to_number): Move here from data.c. Make it static inline.
2416 (E_CHAR, EXP_INT): Remove, replacing with ...
2417 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2418 (string_to_number): New function, replacing isfloat_string.
2419 This function checks for valid syntax and produces the resulting
2420 Lisp float number too. Rework it so that string-to-number
2421 no longer mishandles examples like "1.0e+". Use strtoumax,
2422 so that overflow for non-base-10 numbers is reported only when
2423 there's no portable and simple way to convert to floating point.
2424
2425 * textprop.c (set_text_properties_1): Rewrite for clarity,
2426 and to avoid GCC warning about integer overflow.
2427
2428 * intervals.h (struct interval): Use EMACS_INT for members
2429 where EMACS_UINT might cause problems. See
2430 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2431 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2432 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2433 All uses changed.
2434 (offset_intervals): Tell GCC not to worry about length overflow
2435 when negating a negative length.
2436
2437 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2438 (overrun_check_free): Likewise.
2439
2440 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2441 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2442 word size.
2443
2444 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2445 (gnutls_make_error): Rename local to avoid shadowing.
2446 (gnutls_emacs_global_deinit): ifdef out; not used.
2447 (Fgnutls_boot): Use const for pointer to readonly storage.
2448 Comment out unused local. Fix pointer signedness problems.
2449
2450 * lread.c (openp): Don't stuff size_t into an 'int'.
2451 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2452 about possible signed overflow.
2453
2454 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2455 (GDK_KEY_g): Don't define if already defined.
2456 (xg_prepare_tooltip): Avoid pointer signedness problem.
2457 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2458
2459 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2460 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2461
2462 * xfns.c (Fx_window_property): Simplify a bit,
2463 to make a bit faster and to avoid GCC 4.6.0 warning.
2464 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2465
2466 * fns.c (internal_equal): Don't assume size_t fits in int.
2467
2468 * alloc.c (compact_small_strings): Tighten assertion a little.
2469
2470 Replace pEd with more-general pI, and fix some printf arg casts.
2471 * lisp.h (pI): New macro, generalizing old pEd macro to other
2472 conversion specifiers. For example, use "...%"pI"d..." rather
2473 than "...%"pEd"...".
2474 (pEd): Remove. All uses replaced with similar uses of pI.
2475 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2476 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2477 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2478 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2479 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2480 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2481 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2482 64-bit hosts.
2483 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2484 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2485 * print.c (safe_debug_print, print_object): Likewise.
2486 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2487 to int.
2488 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2489 avoiding the 0 flag, which is not portable.
2490 * process.c (Fmake_network_process): Use pI to avoid cast.
2491 * region-cache.c (pp_cache): Likewise.
2492 * xdisp.c (decode_mode_spec): Likewise.
2493 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2494 behavior on 64-bit hosts with printf arg.
2495 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2496 (x_stop_queuing_selection_requests): Likewise.
2497 (x_get_window_property): Don't truncate byte count to an 'int'
2498 when tracing.
2499
2500 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2501 here, since it parses constructs like leading '-' and spaces,
2502 which are not wanted; and it overflows with large numbers.
2503 Instead, simply match F[0-9]+, which is what is wanted anyway.
2504
2505 * alloc.c: Remove unportable assumptions about struct layout.
2506 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2507 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2508 (allocate_vectorlike, make_pure_vector): Use the new macros,
2509 plus offsetof, to remove unportable assumptions about struct layout.
2510 These assumptions hold on all porting targets that I know of, but
2511 they are not guaranteed, they're easy to remove, and removing them
2512 makes further changes easier.
2513
2514 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2515 This doesn't fix a bug but makes the code clearer.
2516 (string_overrun_cookie): Now const. Use initializers that
2517 don't formally overflow signed char, to avoid warnings.
2518 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2519 can cause Emacs to crash when string overrun checking is enabled.
2520 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2521 multiple of sizeof (EMACS_INT); it need not be, if
2522 alignof(EMACS_INT) < sizeof (EMACS_INT).
2523 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2524

2557 Improve doprnt and its use in verror. (Bug#8545)
2558 * doprnt.c (doprnt): Document the set of format control sequences
2559 supported by the function. Use SAFE_ALLOCA instead of always
2560 using `alloca'.
2561
2562 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2563 is one byte too soon. Don't use xrealloc; instead xfree and
2564 xmalloc anew.
2565
2566 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2567
2568 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
2569 callbacks stage.

2638 changes in globals.h immediately force recompilation.
2639 (TAGS): Depend on $(CURDIR)/m/intel386.h and
2640 $(CURDIR)/s/ms-w32.h.
2641 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

2650 * doprnt.c: Include limits.h.
2651 (SIZE_MAX): New macro.
2652 (doprnt): Return a size_t value. 2nd arg is now size_t.
2653 Many local variables are now size_t instead of int or unsigned.
2654 Improve overflow protection. Support `l' modifier for integer
2655 conversions. Support %l conversion. Don't assume an EMACS_INT
2656 argument for integer conversions and for %c.
2657
2658 * lisp.h (doprnt): Restore prototype.
2659
2660 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

2667
2668 * eval.c (internal_lisp_condition_case): Include the handler
2669 representation in the error message.
2670 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
2671 when breaking from the loop.
2672
2673 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
2674
2675 * callint.c (Fcall_interactively): When displaying error message
2676 about invalid control letter, pass the character's codepoint, not
2677 a pointer to its multibyte form. Improve display of the character
2678 in octal and display also its hex code.
2679
2680 * character.c (char_string): Use %x to display the (unsigned)
2681 codepoint of an invalid character, to avoid displaying a bogus
2682 negative value.

2809 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
2810
2811 * bitmaps: Change bitmaps from unsigned char back to the X11
2812 compatible char. Avoid the old compiler warnings about

2866 (bcmp_translate, regcomp, regexec, print_double_string)
2867 (group_in_compile_stack, re_search, re_search_2, regex_compile)
2868 (re_compile_pattern, re_exec): Declare arguments and local

2881
2882 * nsfont.m: Fixed bugs in ns_get_family and
2883 ns_descriptor_to_entity that were caused by using free to
2884 deallocate memory blocks that were allocated by xmalloc (via
2885 xstrdup). This caused Emacs to crash when compiled with
2886 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
2887 --enable-checking=xmallocoverrun). xfree is now used to
2888 deallocate these memory blocks.

2903 Emacs source code has been audited now.
2904 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
2905 (emacs_read, emacs_write): Use it.
2906 * process.c (send_process): Adjust to the new signatures of
2907 emacs_write and emacs_gnutls_write. Do not attempt to store

2932
2933 * font.c (Qopentype): Don't make static (used from w32uniscribe.c).

3332 * intervals.h (Fprevious_property_change):
3333 (Fremove_list_of_text_properties): Remove decls.
3334 * keyboard.c (Fthis_command_keys): Remove decl.
3335 (Fcommand_execute): New forward static decl.
3336 * keymap.c (Flookup_key): New forward static decl.
3337 (Fcopy_keymap): Now static.
3338 * keymap.h (Flookup_key): Remove decl.
3339 * process.c (Fget_process): New forward static decl.
3340 (Fprocess_datagram_address): Mark as internal.
3341 * syntax.c (Fsyntax_table_p): New forward static decl.
3342 (skip_chars): Remove duplicate decl.
3343 * textprop.c (Fprevious_property_change): New forward static decl.
3344 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
3345 Now internal.
3346 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
3347 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
3348
3349 * editfns.c (Fformat): Remove unreachable code.
3350
3351 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
3352
3353 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
3354 change. (Bug#8496)
3355
3356 2011-04-13 Eli Zaretskii <eliz@gnu.org>
3357
3358 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
3359 when at ZV. (Bug#8487)
3360
3361 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
3362
3363 * charset.c (Fclear_charset_maps): Use xfree instead of free.
3364 (Bug#8437)
3365 * keyboard.c (parse_tool_bar_item): Likewise.
3366 * sound.c (sound_cleanup, alsa_close): Likewise.
3367 * termcap.c (tgetent): Likewise.
3368 * xfns.c (x_default_font_parameter): Likewise.
3369 * xsettings.c (read_and_apply_settings): Likewise.
3370
3371 * alloc.c (overrun_check_malloc, overrun_check_realloc)
3372 (overrun_check_free): Protoize.
3373
3374 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
3375
3376 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
3377 since callers should never pass a negative size.
3378 Change the signature to match that of plain 'read' and 'write'; see
3379 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
3380 * lisp.h: Update prototypes of emacs_write and emacs_read.
3381
3382 2011-04-11 Eli Zaretskii <eliz@gnu.org>
3383
3384 * xdisp.c (redisplay_window): Don't try to determine the character
3385 position of the scroll margin if the window start point w->startp
3386 is outside the buffer's accessible region. (Bug#8468)
3387
3388 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3389
3390 Fix write-region and its subroutines for buffers > 2GB.
3391 * fileio.c (a_write, e_write): Modify declaration of arguments and
3392 local variables to support buffers larger than 2GB.
3393 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3394
3395 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3396 argument, local variables, and return value.
3397
3398 * lisp.h: Update prototypes of emacs_write and emacs_read.
3399
3400 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3401
3402 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3403
3404 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3405
3406 Fix more problems found by GCC 4.6.0's static checks.
3407
3408 * xdisp.c (vmessage): Use a better test for character truncation.
3409
3410 * charset.c (load_charset_map): <, not <=, for optimization,
3411 and to avoid potential problems with integer overflow.
3412 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3413 * casetab.c (set_identity, shuffle): Likewise.
3414 * editfns.c (Fformat): Likewise.
3415 * syntax.c (skip_chars): Likewise.
3416
3417 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3418 This also lets GCC 4.6.0 generate slightly better loop code.
3419
3420 * callint.c (Fcall_interactively): <, not <=, for optimization.
3421 (Fcall_interactively): Count the number of arguments produced,
3422 not the number of arguments given. This is simpler and lets GCC
3423 4.6.0 generate slightly better code.
3424
3425 * ftfont.c: Distingish more carefully between FcChar8 and char.
3426 The previous code passed unsigned char * to a functions like
3427 strlen and xstrcasecmp that expect char *, which does not
3428 conform to the C standard.
3429 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3430 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3431 char * when the C standard requires it.
3432
3433 * keyboard.c (read_char): Remove unused var.
3434
3435 * eval.c: Port to Windows vsnprintf (Bug#8435).
3436 Include <limits.h>.
3437 (SIZE_MAX): Define if the headers do not.
3438 (verror): Do not give up if vsnprintf returns a negative count.
3439 Instead, grow the buffer. This ports to Windows vsnprintf, which
3440 does not conform to C99. Problem reported by Eli Zaretskii.
3441 Also, simplify the allocation scheme, by avoiding the need for
3442 calling realloc, and removing the ALLOCATED variable.
3443
3444 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3445
3446 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3447 But keep the doprint source code for now, as we might revamp it
3448 and use it again (Bug#8435).
3449 * lisp.h (doprnt): Remove.
3450 * Makefile.in (base_obj): Remove doprnt.o.
3451 * deps.mk (doprnt.o): Remove.
3452
3453 error: Print 32- and 64-bit integers portably (Bug#8435).
3454 Without this change, on typical 64-bit hosts error ("...%d...", N)
3455 was used to print both 32- and 64-bit integers N, which relied on
3456 undefined behavior.
3457 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3458 New macro.
3459 * lisp.h (error, verror): Mark as printf-like functions.
3460 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3461 Report overflow in size calculations when allocating printf buffer.
3462 Do not truncate output string at its first null byte.
3463 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3464 Truncate the output at a character boundary, since vsnprintf does not
3465 do that.
3466 * charset.c (check_iso_charset_parameter): Convert internal
3467 character to string before calling 'error', since %c now has the
3468 printf meaning.
3469 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3470 overflow when computing char to be passed to 'error'. Do not
3471 pass Lisp_Object to 'error'; pass the integer instead.
3472 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3473 formatted with plain %d.
3474
3475 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3476
3477 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3478
3479 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3480
3481 * xterm.c (x_catch_errors): Remove duplicate declaration.
3482
3483 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3484
3485 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3486
3487 2011-04-10 Jim Meyering <meyering@redhat.com>
3488
3489 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3490 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3491 return ssize_t not "int", and use size_t as the buffer length.
3492 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3493 * gnutls.h: Update declarations.
3494 * process.c (read_process_output): Use ssize_t, to match.
3495 (send_process): Likewise.
3496
3497 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3498
3499 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3500
3501 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3502
3503 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3504 Use unsigned char, to match FcChar8 type definition.
3505
3506 * xterm.c (handle_one_xevent):
3507 * xmenu.c (create_and_show_popup_menu):
3508 * xselect.c (x_decline_selection_request)
3509 (x_reply_selection_request): Avoid type-punned deref of X events.
3510
3511 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3512
3513 Fix some uses of `int' instead of EMACS_INT.
3514 * search.c (string_match_1, fast_string_match)
3515 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
3516 (scan_buffer, find_next_newline_no_quit)
3517 (find_before_next_newline, search_command, Freplace_match)
3518 (Fmatch_data): Make some `int' variables be EMACS_INT.
3519
3520 * xdisp.c (display_count_lines): 3rd argument and return value now
3521 EMACS_INT. All callers changed.
3522 (pint2hrstr): Last argument is now EMACS_INT.
3523
3524 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
3525 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
3526 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
3527 (decode_coding_utf_16, decode_coding_emacs_mule)
3528 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
3529 (decode_coding_ccl, decode_coding_charset)
3530 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
3531 (decode_coding_iso_2022, decode_coding_emacs_mule)
3532 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
3533 <char_offset, last_offset>: Declare EMACS_INT.
3534 (encode_coding_utf_8, encode_coding_utf_16)
3535 (encode_coding_emacs_mule, encode_invocation_designation)
3536 (encode_designation_at_bol, encode_coding_iso_2022)
3537 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
3538 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
3539 Declare EMACS_INT.
3540 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
3541 (encode_invocation_designation): Last argument P_NCHARS is now
3542 EMACS_INT.
3543 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
3544 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
3545
3546 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
3547 All users changed.
3548
3549 * ccl.c (Fccl_execute_on_string): Declare some variables
3550 EMACS_INT.
3551
3552 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
3553
3554 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
3555
3556 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
3557
3558 * process.c (Fformat_network_address): Doc fix.
3559
3560 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
3561
3562 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
3563
3564 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
3565
3566 * keyboard.c (read_char): Call Lisp function help-form-show,
3567 instead of using internal_with_output_to_temp_buffer.
3568 (Qhelp_form_show): New var.
3569 (syms_of_keyboard): Use DEFSYM macro.
3570
3571 * print.c (internal_with_output_to_temp_buffer): Function deleted.
3572
3573 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
3574
3575 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
3576
3577 * process.c (Flist_processes): Remove to Lisp.
3578 (list_processes_1): Delete.
3579
3580 2011-04-06 Eli Zaretskii <eliz@gnu.org>
3581
3582 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
3583
3584 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
3585
3586 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3587
3588 Fix more problems found by GCC 4.6.0's static checks.
3589
3590 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3591
3592 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3593
3594 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
3595
3596 * xdisp.c (vmessage): Mark as a printf-like function.
3597
3598 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
3599
3600 * sound.c (sound_warning): Don't crash if arg contains a printf format.
3601
3602 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
3603 printf-like functions.
3604 (tiff_load): Add casts to remove these marks before passing them
3605 to system-supplied API.
3606
3607 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3608
3609 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3610 This avoids several warnings with gcc -Wstrict-overflow.
3611 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3612 directly, rather than having caller test rule sign. This avoids
3613 some unnecessary tests.
3614 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3615 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3616 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
3617
3618 * xfont.c (xfont_text_extents): Remove var that was set but not used.
3619 (xfont_open): Avoid unnecessary tests.
3620
3621 * composite.c (composition_gstring_put_cache): Use unsigned integer.

3627 breaking out part of COMPOSITION_DECODE_RULE.
3628 (COMPOSITION_DECODE_RULE): Use it.
3629 * composite.c (get_composition_id): Remove unused local vars,
3630 by using the new macro.
3631
3632 * textprop.c (set_text_properties_1): Change while to do-while,
3633 since the condition is always true at first.
3634
3635 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3636 (interval_deletion_adjustment): Return unsigned value.
3637 All uses changed.
3638
3639 * process.c (list_processes_1, create_pty, read_process_output):
3640 (exec_sentinel): Remove vars that were set but not used.
3641 (create_pty): Remove unnecessary "volatile"s.
3642 (Fnetwork_interface_info): Avoid possibility of int overflow.
3643 (read_process_output): Do adaptive read buffering even if carryover.
3644 (read_process_output): Simplify nbytes computation if buffered.
3645
3646 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
3647
3648 * syntax.c (scan_words): Remove var that was set but not used.
3649 (update_syntax_table): Use unsigned instead of int.
3650
3651 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
3652 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
3653 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
3654
3655 * print.c (print_error_message): Avoid int overflow.
3656
3657 * font.c (font_list_entities): Redo for clarity,
3658 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
3659
3660 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3661 (font_score): Avoid potential overflow in diff calculation.
3662
3663 * fns.c (substring_both): Remove var that is set but not used.
3664 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3665
3666 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3667
3668 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3669 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3670 can always succeed if overflow has undefined behavior.
3671
3672 * search.c (boyer_moore, wordify): Remove vars set but not used.
3673 (wordify): Omit three unnecessary tests.
3674
3675 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3676 All callers changed. This avoids the need for an unused var.
3677
3678 * casefiddle.c (casify_region): Remove var that is set but not used.
3679
3680 * dired.c (file_name_completion): Remove var that is set but not used.
3681
3682 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3683
3684 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3685 (Finsert_file_contents): Remove unnecessary code checking fd.
3686
3687 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3688 Check for integer overflow on size calculations.
3689
3690 * buffer.c (Fprevious_overlay_change): Remove var that is set
3691 but not used.
3692
3693 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3694 Remove vars that are set but not used.
3695 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3696 (timer_check_2): Mark vars as initialized.
3697
3698 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3699
3700 * image.c (lookup_image): Remove var that is set but not used.
3701 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3702
3703 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3704 that are set but not used.
3705
3706 * xfns.c (make_invisible_cursor): Don't return garbage
3707 if XCreateBitmapFromData fails (Bug#8410).
3708
3709 * xselect.c (x_get_local_selection, x_handle_property_notify):
3710 Remove vars that are set but not used.
3711
3712 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

3714
3715 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
3716 Remove var that is set but not used.
3717 (scroll_bar_windows_size): Now size_t, not int.
3718 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
3719 Check for overflow.
3720
3721 * xfaces.c (realize_named_face): Remove vars that are set but not used.
3722 (map_tty_color) [!defined MSDOS]: Likewise.
3723
3724 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
3725
3726 * coding.c: Remove vars that are set but not used.
3727 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3728 All callers changed.
3729 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3730 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3731 (decode_coding_charset): Remove vars that are set but not used.
3732
3733 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3734 that is set but not used.
3735
3736 * print.c (print_object): Remove var that is set but not used.
3737
3738 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3739 The gnulib version avoids calling malloc in the usual case,
3740 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3741 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3742 * filelock.c (current_lock_owner): Likewise.
3743 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3744 * sysdep.c: Include allocator.h, careadlinkat.h.
3745 (emacs_no_realloc_allocator): New static constant.
3746 (emacs_readlink): New function.
3747 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
3748 ../lib/careadlinkat.h.
3749
3750 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
3751
3752 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

3755 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
3756
3757 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
3758 if not defined (Bug#8403).
3759

3761
3762 * xdisp.c (display_count_lines): Remove parameter `start',

3788

3790
3791 * window.c (Ftemp_output_buffer_show): New fun.
3792 (Fsave_window_excursion):

3794
3795 * lread.c (lisp_file_lexically_bound_p): New function.
3796 (Fload): Bind Qlexical_binding.
3797 (readevalloop): Remove `evalfun' arg.
3798 Bind Qinternal_interpreter_environment.
3799 (Feval_buffer): Bind Qlexical_binding.
3800 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3801 Mark as dynamic.
3802 (syms_of_lread): Declare `lexical-binding'.
3803
3804 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
3805
3806 * keyboard.c (eval_dyn): New fun.
3807 (menu_item_eval_property): Use it.
3808
3809 * image.c (parse_image_spec): Use Ffunctionp.
3810
3811 * fns.c (concat, mapcar1): Accept byte-code-functions.
3812
3813 * eval.c (Fsetq): Handle lexical vars.
3814 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3815 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3816 (FletX, Flet): Obey lexical binding.
3817 (Fcommandp): Handle closures.
3818 (Feval): New `lexical' arg.
3819 (eval_sub): New function extracted from Feval. Use it almost
3820 everywhere where Feval was used. Look up vars in lexical env.
3821 Handle closures.
3822 (Ffunctionp): Move from subr.el.
3823 (Ffuncall): Handle closures.
3824 (apply_lambda): Remove `eval_flags'.
3825 (funcall_lambda): Handle closures and new byte-code-functions.
3826 (Fspecial_variable_p): New function.
3827 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3828 but without exporting it to Lisp.
3829

3832
3833 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3834 interactive spec.
3835
3836 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3837 New byte-codes.
3838 (exec_byte_code): New function extracted from Fbyte_code to handle new
3839 calling convention for byte-code-functions. Add new byte-codes.
3840
3841 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3842
3843 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3844
3845 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3846
3847 * xdisp.c (redisplay_internal): Fix prototype.
3848
3849 2011-03-31 Eli Zaretskii <eliz@gnu.org>
3850
3851 * xdisp.c (SCROLL_LIMIT): New macro.
3852 (try_scrolling): Use it when setting scroll_limit.
3853 Limit scrolling to 100 screen lines.
3854 (redisplay_window): Even when falling back on "recentering",
3855 position point in the window according to scroll-conservatively,
3856 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3857
3858 (try_scrolling): When point is above the window, allow searching
3859 as far as scroll_max, or one screenful, to compute vertical
3860 distance from PT to the scroll margin position. This prevents
3861 try_scrolling from unnecessarily failing when
3862 scroll-conservatively is set to a value slightly larger than the
3863 window height. Clean up the case of PT below the margin at bottom
3864 of window: scroll_max can no longer be INT_MAX. When aggressive
3865 scrolling is in use, don't let point enter the opposite scroll
3866 margin as result of the scroll.
3867 (syms_of_xdisp) <scroll-conservatively>: Document the
3868 threshold of 100 lines for never-recentering scrolling.

3876 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3877 (redisplay_internal): Remove parameter `preserve_echo_area',
3878 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3879
3880 * indent.c (Fvertical_motion):
3881 * window.c (window_scroll_pixel_based, Frecenter):
3882 Don't pass `need_y_p' to `move_it_by_lines'.
3883
3884 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3885
3886 * eval.c (struct backtrace): Don't cheat with negative numbers, but do

3890

3896 binding" message (bug#7967).
3897
3898 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3899
3900 Fix more problems found by GCC 4.6.0's static checks.
3901
3902 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3903 Remove unused local var.
3904
3905 * editfns.c (Fmessage_box): Remove unused local var.
3906
3907 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3908 (note_mode_line_or_margin_highlight, note_mouse_highlight):
3909 Omit unused local vars.
3910 * window.c (shrink_windows): Omit unused local var.
3911 * menu.c (digest_single_submenu): Omit unused local var.
3912 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
3913 Omit unused local var.
3914
3915 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
3916 Don't assume string length fits in int.
3917 (keyremap_step, read_key_sequence): Use size_t for sizes.
3918 (read_key_sequence): Don't check last_real_key_start redundantly.
3919
3920 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3921 instead of alloca (Bug#8344).
3922
3923 * eval.c (Fbacktrace): Don't assume nargs fits in int.
3924 (Fbacktrace_frame): Don't assume nframes fits in int.
3925
3926 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
3927
3928 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
3929 concerns.
3930
3931 * term.c (produce_glyphless_glyph): Remove unnecessary test.
3932
3933 * cm.c (calccost): Turn while-do into do-while, for clarity.
3934
3935 * keyboard.c (syms_of_keyboard): Use the same style as later
3936 in this function when indexing through an array. This also
3937 works around GCC bug 48267.
3938
3939 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3940

3944 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3945
3946 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3947 This avoids undefined behavior on integer overflow, and is a bit
3948 more convenient anyway since it is compared to a size_t variable.
3949
3950 Variadic C functions now count arguments with size_t, not int.
3951 This avoids an unnecessary limitation on 64-bit machines, which
3952 caused (substring ...) to crash on large vectors (Bug#8344).

3961 (funcall_lambda, mark_backtrace): Likewise.
3962 * fns.c (concat): Likewise.
3963 * frame.c (x_set_frame_parameters): Likewise.
3964 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3965 0 if not found, not -1. All callers changed.
3966
3967 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3968 (stack_copy_size): Now size_t, not int.
3969 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

3994 Vcommand_hook_internal.
3995

4163
4164 * term.c (Fsuspend_tty, Fresume_tty):
4165 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
4166 * window.c (temp_output_buffer_show):
4167 * insdel.c (signal_before_change):
4168 * frame.c (Fhandle_switch_frame):
4169 * fileio.c (Fdo_auto_save):
4170 * emacs.c (Fkill_emacs):
4171 * editfns.c (save_excursion_restore):
4172 * cmds.c (internal_self_insert):
4173 * callint.c (Fcall_interactively):
4174 * buffer.c (Fkill_all_local_variables):
4175 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
4176 Use Frun_hooks.
4177 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
4178 unconditionnaly since it does the check itself.
4179
4180 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
4181
4182 Fix more problems found by GCC 4.5.2's static checks.
4183
4184 * coding.c (encode_coding_raw_text): Avoid unnecessary test
4185 the first time through the loop, since we know p0 < p1 then.
4186 This also avoids a gcc -Wstrict-overflow warning.
4187
4188 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
4189 leading to a memory leak, possible in functions like
4190 load_charset_map_from_file that can allocate an unbounded number
4191 of objects (Bug#8318).
4192
4193 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
4194 that could (at least in theory) be that large.
4195
4196 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
4197 This is less likely to overflow, and avoids undefined behavior if
4198 overflow does occur. All callers changed. Use strtoul to scan
4199 for the unsigned long integer.
4200 (pint2hrstr): Simplify and tune code slightly.
4201 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
4202
4203 * scroll.c (do_scrolling): Work around GCC bug 48228.
4204 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
4205
4206 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
4207 This also avoids a warning with gcc -Wstrict-overflow.
4208 (validate_x_resource_name): Simplify count usage.
4209 This also avoids a warning with gcc -Wstrict-overflow.
4210
4211 * fileio.c (Fcopy_file): Report error if fchown or fchmod
4212 fail (Bug#8306).
4213
4214 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
4215
4216 * process.c (Fmake_network_process): Use socklen_t, not int,
4217 where POSIX says socklen_t is required in portable programs.
4218 This fixes a porting bug on hosts like 64-bit HP-UX, where
4219 socklen_t is wider than int (Bug#8277).
4220 (Fmake_network_process, server_accept_connection):
4221 (wait_reading_process_output, read_process_output):
4222 Likewise.
4223
4224 * process.c: Rename or move locals to avoid shadowing.
4225 (list_processes_1, Fmake_network_process):
4226 (read_process_output_error_handler, exec_sentinel_error_handler):
4227 Rename or move locals.
4228 (Fmake_network_process): Define label "retry_connect" only if needed.
4229 (Fnetwork_interface_info): Fix pointer signedness.
4230 (process_send_signal): Add cast to avoid pointer signedness problem.
4231 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
4232 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
4233
4234 Make tparam.h and terminfo.c consistent.
4235 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
4236 Include tparam.h instead, since it declares them.
4237 * cm.h (PC): Remove extern decl; tparam.h now does this.
4238 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
4239 * terminfo.c: Include tparam.h, to check interfaces.
4240 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
4241 (tparam): Adjust signature to match interface in tparam.h;
4242 this removes some undefined behavior. Check that outstring and len
4243 are zero, which they always are with Emacs.
4244 * tparam.h (PC, BC, UP): New extern decls.
4245
4246 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
4247 (xftfont_open): Rename locals to avoid shadowing.
4248
4249 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
4250 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
4251 (OTF_TAG_SYM): Omit macro if not needed.
4252 (ftfont_list): Remove unused local.

4254 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
4255 Rename locals to avoid shadowing.
4256
4257 * xfont.c (xfont_list_family): Mark var as initialized.
4258
4259 * xml.c (make_dom): Now static.
4260
4261 * composite.c (composition_compute_stop_pos): Rename local to
4262 avoid shadowing.
4263 (composition_reseat_it): Remove unused locals.
4264 (find_automatic_composition, composition_adjust_point): Likewise.
4265 (composition_update_it): Mark var as initialized.
4266 (find_automatic_composition): Mark vars as initialized,
4267 with a FIXME (Bug#8290).
4268
4269 character.h: Rename locals to avoid shadowing.
4270 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
4271 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
4272 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
4273 (BUF_DEC_POS): Be more systematic about renaming local temporaries
4274 to avoid shadowing.
4275
4276 * textprop.c (property_change_between_p): Remove; unused.
4277
4278 * intervals.c (interval_start_pos): Now static.
4279

4281
4282 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
4283 Rename locals to avoid shadowing.
4284
4285 * sound.c (wav_play, au_play, Fplay_sound_internal):
4286 Fix pointer signedness.
4287 (alsa_choose_format): Remove unused local var.
4288 (wav_play): Initialize a variable to 0, to prevent undefined
4289 behavior (Bug#8278).
4290
4291 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
4292
4293 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
4294
4295 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
4296 clobbering (Bug#8298).
4297 * sysdep.c (sys_subshell): Likewise.
4298 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
4299
4300 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
4301 This should get cleaned up, so that child_setup has the
4302 same signature on all platforms.
4303
4304 * callproc.c (call_process_cleanup): Now static.
4305 (relocate_fd): Rename locals to avoid shadowing.
4306
4307 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
4308
4309 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
4310 not to be necessary, and produces flickering.
4311
4312 2011-03-20 Glenn Morris <rgm@gnu.org>
4313
4314 * config.in: Remove file.
4315
4316 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
4317
4318 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
4319 are now in src/globals.h.
4320 (syms_of_minibuf): Remove spurious & from previous change.
4321
4322 2011-03-20 Leo <sdl.web@gmail.com>
4323
4324 * minibuf.c (completing-read-function): New variable.
4325 (completing-read-default): Rename from completing-read.
4326 (completing-read): Call completing-read-function.
4327
4328 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
4329
4330 * xfaces.c (Fx_load_color_file):
4331 Read color file from absolute filename (bug#8250).
4332
4333 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
4334
4335 * makefile.w32-in: Update dependencies.
4336
4337 2011-03-17 Eli Zaretskii <eliz@gnu.org>
4338
4339 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
4340
4341 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

4346 (sigchld_handler): Now static.
4347
4348 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
4349 That way, the code declares only the vars that it needs.
4350 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
4351 * s/cygwin.h (PTY_ITERATION): Likewise.
4352 * s/darwin.h (PTY_ITERATION): Likewise.
4353 * s/gnu-linux.h (PTY_ITERATION): Likewise.
4354
4355 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
4356 * process.c (allocate_pty): Don't declare stb unless it's needed.
4357
4358 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
4359 (CONSTANTLIM): Remove; unused.
4360 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
4361 Define only if needed.
4362
4363 * unexelf.c (unexec): Name an expression,
4364 to avoid gcc -Wbad-function-cast warning.
4365 Use a different way to cause a compilation error if anyone uses
4366 n rather than nn, a way that does not involve shadowing.
4367 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
4368
4369 * deps.mk (unexalpha.o): Remove; unused.
4370
4371 New file unexec.h, the (simple) interface for unexec (Bug#8267).
4372 * unexec.h: New file.
4373 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
4374 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
4375 Depend on unexec.h.
4376 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
4377 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
4378 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
4379 Change as necessary to match prototype in unexec.h.
4380
4381 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
4382 shadowing.
4383 (back_comment, skip_chars): Mark vars as initialized.
4384

4390
4391 * print.c (Fredirect_debugging_output): Fix pointer signedess.
4392
4393 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
4394 warning when compiling print.c.
4395
4396 * font.c (font_unparse_fcname): Abort in an "impossible" situation
4397 instead of using an uninitialized var.
4398 (font_sort_entities): Mark var as initialized.
4399
4400 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
4401
4402 * font.c (font_unparse_xlfd): Don't mix pointers to variables with
4403 pointers to constants.

4407 (font_style_to_value, font_prop_validate_style, font_unparse_fcname):
4408 (font_update_drivers, Ffont_get_glyphs, font_add_log):
4409 Rename or move locals to avoid shadowing.
4410
4411 * fns.c (require_nesting_list, require_unwind): Now static.
4412 (Ffillarray): Rename locals to avoid shadowing.
4413
4414 * floatfns.c (domain_error2): Define only if needed.
4415 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
4416
4417 * alloc.c (mark_backtrace): Move decl from here ...
4418 * lisp.h: ... to here, so that it can be checked.
4419
4420 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
4421 (Fdefvar): Rewrite so as not to use empty "else".
4422 (lisp_indirect_variable): Name an expression,
4423 to avoid gcc -Wbad-function-cast warning.
4424 (Fdefvar): Rename locals to avoid shadowing.
4425
4426 * callint.c (quotify_arg, quotify_args): Now static.
4427 (Fcall_interactively): Rename locals to avoid shadowing.
4428 Use const pointer when appropriate.
4429
4430 * lisp.h (get_system_name, get_operating_system_release):
4431 Move decls here, to check interfaces.
4432 * process.c (get_operating_system_release): Move decl to lisp.h.
4433 * xrdb.c (get_system_name): Likewise.
4434 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
4435 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
4436 some of which prompt warnings from gcc -Wbad-function-cast.
4437 (Fformat_time_string, Fencode_time, Finsert_char):
4438 (Ftranslate_region_internal, Fformat):
4439 Rename or remove local vars to avoid shadowing.
4440 (Ftranslate_region_internal): Mark var as initialized.
4441
4442 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
4443 avoid shadowing.
4444
4445 * lisp.h (eassert): Check that the argument compiles, even if
4446 ENABLE_CHECKING is not defined.
4447
4448 * data.c (Findirect_variable): Name an expression, to avoid
4449 gcc -Wbad-function-cast warning.
4450 (default_value, arithcompare, arith_driver, arith_error): Now static.
4451 (store_symval_forwarding): Rename local to avoid shadowing.
4452 (Fmake_variable_buffer_local, Fmake_local_variable):
4453 Mark variables as initialized.
4454 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
4455

4457 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
4458 Rename locals to avoid shadowing.
4459 (mark_stack): Move local variables into the #ifdef region where
4460 they're used.
4461 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
4462 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
4463 needed otherwise.
4464 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
4465 (GC_STRING_CHARS): Remove; not used.
4466 (Fmemory_limit): Cast sbrk's returned value to char *.
4467
4468 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
4469 avoids undefined behavior in theory.
4470
4471 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4472
4473 Use functions, not macros, for up- and down-casing (Bug#8254).
4474 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4475 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4476 to use the following functions instead of these macros.
4477 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4478 EMACS_INT, since callers assume the returned value fits in int.
4479 (upcase1): Likewise, for UPCASE_TABLE.
4480 (uppercasep, lowercasep, upcase): New static inline functions.
4481 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
4482 the race-condition problem in the old DOWNCASE.
4483
4484 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
4485 Rename locals to avoid shadowing.
4486 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
4487 (regex_compile, re_search_2, re_match_2_internal):
4488 Remove unused local vars.
4489 (FREE_VAR): Rewrite so as not to use empty "else",
4490 which gcc can warn about.
4491 (regex_compile, re_match_2_internal): Mark locals as initialized.
4492 (RETALLOC_IF): Define only if needed.
4493 (WORDCHAR_P): Likewise. This one is never needed, but is used
4494 only in a comment talking about a compiler bug, so put inside
4495 the #if 0 of that comment.
4496 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4497 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4498 Remove; unused.
4499
4500 * search.c (boyer_moore): Rename locals to avoid shadowing.
4501 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
4502 (PREV_CHAR_BOUNDARY): Likewise.
4503
4504 * search.c (simple_search): Remove unused var.
4505
4506 * dired.c (compile_pattern): Move decl from here ...
4507 * lisp.h: ... to here, so that it can be checked.
4508 (struct re_registers): New forward decl.
4509
4510 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
4511
4512 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
4513 All uses changed.
4514 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
4515 Rename locals to avoid shadowing.
4516 (Fvertical_motion): Mark locals as initialized.
4517
4518 * casefiddle.c (casify_object, casify_region): Now static.
4519 (casify_region): Mark local as initialized.
4520
4521 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
4522
4523 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4524 New macros, so that the caller can use some names other than
4525 gcpro1, gcpro2, etc.
4526 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
4527 of the new macros.
4528 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
4529 argument, for consistency with GCPRO2_VAR, etc: it is now the
4530 prefix of the variable, not the variable itself. All uses
4531 changed.
4532 * dired.c (directory_files_internal, file_name_completion):
4533 Rename locals to avoid shadowing.
4534
4535 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4536 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
4537 dired.c's scmp function, had undefined behavior.
4538 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4539 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4540 * buffer.h: ... to here, because these macros use current_buffer,
4541 and the new implementation with inline functions needs to have
4542 current_buffer in scope now, rather than later when the macros
4543 are used.
4544 (downcase, upcase1): New static inline functions.
4545 (DOWNCASE, UPCASE1): Reimplement using these functions.
4546 This avoids undefined behavior in expressions like
4547 DOWNCASE (x) == DOWNCASE (y), which previously suffered
4548 from race conditions in accessing the global variables
4549 case_temp1 and case_temp2.
4550 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
4551 * lisp.h (case_temp1, case_temp2): Remove their decls.
4552 * character.h (ASCII_CHAR_P): Move from here ...
4553 * lisp.h: ... to here, so that the inline functions mentioned
4554 above can use them.
4555
4556 * dired.c (directory_files_internal_unwind): Now static.
4557
4558 * fileio.c (file_name_as_directory, directory_file_name):
4559 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
4560 Now static.
4561 (file_name_as_directory): Use const pointers when appropriate.
4562 (Fexpand_file_name): Likewise. In particular, newdir might
4563 point at constant storage, so make it a const pointer.
4564 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
4565 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
4566 signedness issues.
4567 (Fset_file_times, Finsert_file_contents, auto_save_error):
4568 Rename locals to avoid shadowing.
4569
4570 * minibuf.c (choose_minibuf_frame_1): Now static.
4571 (Ftry_completion, Fall_completions): Rename or remove locals
4572 to avoid shadowing.
4573
4574 * marker.c (bytepos_to_charpos): Remove; unused.
4575
4576 * lisp.h (verify_bytepos, count_markers): New decls,
4577 so that gcc does not warn that these functions aren't declared.
4578
4579 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
4580 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
4581 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
4582 (copy_text): Remove unused local var.
4583
4584 * filelock.c (within_one_second): Now static.
4585 (lock_file_1): Rename local to avoid shadowing.
4586

4997 Move these decls to tparam.h, and make them agree with what
4998 is actually in tparam.c. The previous trick of using incompatible
4999 decls in different modules does not conform to the C standard.

5002 Use const pointers where appropriate.

5012
5013 * term.c (term_mouse_position): Rename local to avoid shadowing.
5014
5015 * alloc.c (mark_ttys): Move decl from here ...
5016 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
