- * coding.c (coding_alloc_by_realloc):
- * doprnt.c (doprnt):
- * editfns.c (Fformat):
- * eval.c (verror):
- Use STRING_BYTES_MAX, not MOST_POSITIVE_FIXNUM,
- since they may not be the same number.
- * editfns.c (Finsert_char):
- * fileio.c (Finsert_file_contents):
- Likewise for BUF_BYTES_MAX.
-
- Use ptrdiff_t, not int, for sizes.
- * image.c (slurp_file): Switch from int to ptrdiff_t.
- All uses changed.
- (slurp_file): Check that file size fits in both size_t (for

+2011-06-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * lread.c (Fload): Don't compare a possibly-garbage time_t value.
+
+ GLYPH_CODE_FACE returns EMACS_INT, not int.
+ * dispextern.h (merge_faces):
+ * xfaces.c (merge_faces):
+ * xdisp.c (get_next_display_element):
+ (next_element_from_display_vector): Don't assume EMACS_INT fits in int.
+
+ * character.h (CHAR_VALID_P): Remove unused parameter.
+ * fontset.c, lisp.h, xdisp.c: All uses changed.
+
+ * editfns.c (Ftranslate_region_internal): Omit redundant test.
+
+ * fns.c (concat): Minor tuning based on overflow analysis.
+ This doesn't fix any bugs. Use int to hold character, instead
+ of constantly refetching from Emacs object. Use XFASTINT, not
+ XINT, for value known to be a character. Don't bother comparing
+ a single byte to 0400, as it's always less.
+
+ * floatfns.c (Fexpt):
+ * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
+
+ * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
+ for characters.
+
+ * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
+
+ * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
+ Without this fix, on a 64-bit host (aset S 0 4294967386) would
+ incorrectly succeed when S was a string, because 4294967386 was
+ truncated before it was used.
+
+ * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
+ Otherwise, an out-of-range integer could cause undefined behavior
+ on a 64-bit host.
+
+ * composite.c: Use int, not EMACS_INT, for characters.
+ (fill_gstring_body, composition_compute_stop_pos): Use int, not
+ EMACS_INT, for values that are known to be in character range.
+ This doesn't fix any bugs but is the usual style inside Emacs and
+ may generate better code on 32-bit machines.
+
+ Make sure a 64-bit char is never passed to ENCODE_CHAR.
+ This is for reasons similar to the recent CHAR_STRING fix.
+ * charset.c (Fencode_char): Check that character arg is actually
+ a character. Pass an int to ENCODE_CHAR.
+ * charset.h (ENCODE_CHAR): Verify that the character argument is no
+ wider than 'int', as a compile-time check to prevent future regressions
+ in this area.
+
+ * character.c (char_string): Remove unnecessary casts.
+
+ Make sure a 64-bit char is never passed to CHAR_STRING.
+ Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
+ by silently ignoring the top 32 bits, allowing some values
+ that were far too large to be valid characters.
+ * character.h: Include <verify.h>.
+ (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
+ arguments are no wider than unsigned, as a compile-time check
+ to prevent future regressions in this area.
+ * data.c (Faset):
+ * editfns.c (Fchar_to_string, general_insert_function, Finsert_char):
+ (Fsubst_char_in_region):
+ * fns.c (concat):
+ * xdisp.c (decode_mode_spec_coding):
+ Adjust to CHAR_STRING's new requirement.
+ * editfns.c (Finsert_char, Fsubst_char_in_region):
+ * fns.c (concat): Check that character args are actually
+ characters. Without this test, these functions did the wrong
+ thing with wildly out-of-range values on 64-bit hosts.
+
+2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
+ These casts should not be needed on 32-bit hosts, either.
+ * keyboard.c (read_char):
+ * lread.c (Fload): Remove casts to unsigned.
+
+ * lisp.h (UNSIGNED_CMP): New macro.
+ This fixes comparison bugs on 64-bit hosts.

+2011-06-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
+ not to EMACS_INT, to avoid GCC warning.
+
+ * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
+
+ * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
+ The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
+ isn't needed on 32-bit machines.
+
+ * buffer.c (Fgenerate_new_buffer_name): Use EMACS_INT for count, not int.
+ (advance_to_char_boundary): Return EMACS_INT, not int.

+ ptrdiff_t, not int.
+ (mark_object): Use ptrdiff_t, not int.
+ * lisp.h (pD): New macro.
+ * print.c (print_object): Use it.

+ (total_free_conses, total_free_markers, total_free_symbols)
+ (total_free_floats, total_floats, total_free_intervals, total_intervals)
+ (total_strings, total_free_strings):
+ Now EMACS_INT, not int. All uses changed.
+ (Fgarbage_collect): Compute overall total using a double, so that
+ integer overflow is less likely to be a problem. Check for overflow
+ when converting back to an integer.
+ (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
+ (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
+ These were 'int' variables that could overflow on 64-bit hosts;
+ they were never used, so remove them instead of repairing them.
+ (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
+ (inhibit_garbage_collection): Set gc_cons_threshold to max value.
+ Previously, this ceilinged at INT_MAX, but that doesn't work on
+ 64-bit machines.
+ (allocate_pseudovector): Don't use EMACS_INT when int would do.
+
+ * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
+ (allocate_vectorlike): Check for ptrdiff_t overflow.
+ (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
+ when a (possibly-narrower) signed value would do just as well.
+ We prefer using signed arithmetic, to avoid comparison confusion.
+
+ * alloc.c: Catch some string size overflows that we were missing.
+ (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
+ for convenience in STRING_BYTES_MAX.
+ (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
+ The definition here is exact; the one in lisp.h was approximate.
+ (allocate_string_data): Check for string overflow. This catches
+ some instances we weren't catching before. Also, it catches
+ size_t overflow on (unusual) hosts where SIZE_MAX <= min
+ (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
+ and ptrdiff_t and EMACS_INT are both 64 bits.
+
+ * character.c, coding.c, doprnt.c, editfns.c, eval.c:
+ All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
+ * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
+
+ * character.c (string_escape_byte8): Fix nbytes/nchars typo.
+
+ * alloc.c (Fmake_string): Check for out-of-range init.

+ * bidi.c (bidi_level_of_next_char): Fix last change.
+
+2011-06-03 Eli Zaretskii <eliz@gnu.org>
+
+ Support bidi reordering of text covered by display properties.
+
+ * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
+ (bidi_fetch_char, bidi_fetch_char_advance): New functions.
+ (bidi_cache_search, bidi_cache_iterator_state)
+ (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
+ (bidi_level_of_next_char, bidi_move_to_visually_next):
+ Support character positions inside a run of characters covered by a
+ display string.
+ (bidi_paragraph_init, bidi_resolve_explicit_1)
+ (bidi_level_of_next_char): Call bidi_fetch_char and
+ bidi_fetch_char_advance instead of FETCH_CHAR and
+ FETCH_CHAR_ADVANCE.
+ (bidi_init_it): Initialize new members.
+ (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
+ definitions.
+ (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
+ instead of using explicit *_CHAR codes.
+ (bidi_resolve_explicit, bidi_resolve_weak):
+ Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
+ bidirectional text is supported only in multibyte buffers.
+ (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
+ it to initialize the frame_window_p member of struct bidi_it.
+ (bidi_cache_iterator_state, bidi_resolve_explicit_1)
+ (bidi_resolve_explicit, bidi_resolve_weak)
+ (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
+ bidi_it->nchars is non-positive.
+ (bidi_level_of_next_char): Don't try to lookup the cache for the
+ next/previous character if nothing is cached there yet, or if we
+ were just reseat()'ed to a new position.
+
+ * xdisp.c (set_cursor_from_row): Set start and stop points
+ according to the row's direction when priming the loop that looks
+ for the glyph on which to display cursor.

+ (display_prop_intangible_p): Reimplement to call
+ handle_display_spec instead of single_display_spec_intangible_p.
+ Accept 3 additional arguments needed by handle_display_spec.
+ This fixes incorrect cursor motion across display property with complex
+ values: lists, `(when COND...)' forms, etc.
+ (single_display_spec_string_p): Support property values that are
+ lists with the argument STRING its top-level element.
+ (display_prop_string_p): Fix the condition for processing a
+ property that is a list to be consistent with handle_display_spec.
+ (handle_display_spec): New function, refactored from the
+ last portion of handle_display_prop.
+ (compute_display_string_pos): Accept additional argument
+ FRAME_WINDOW_P. Call handle_display_spec to determine whether the
+ value of a `display' property is a "replacing spec".
+ (handle_single_display_spec): Accept 2 additional arguments BUFPOS
+ and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
+ the display property, but just return a value indicating whether
+ the display property will replace the characters it covers.
+ (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
+ frame_window_p members of struct bidi_it.
+ (compute_display_string_pos, compute_display_string_end):

+ jump to continue iteration.
+ (reseat_1): Initialize bidi_it.disp_pos.
+
