+ Use ptrdiff_t for composition IDs.
+ * character.c (lisp_string_width):
+ * composite.c (composition_table_size, n_compositions)
+ (get_composition_id, composition_gstring_from_id):
+ * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):
+ * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING):
+ * window.c (Frecenter):
+ Use ptrdiff_t, not int, for composition IDs.
+ * composite.c (get_composition_id): Check for integer overflow.
+ * composite.h: Adjust prototypes to match the above changes.
+
+ Use ptrdiff_t for hash table indexes.
+ * category.c (hash_get_category_set):
+ * ccl.c (ccl_driver):
+ * charset.h (struct charset.hash_index, CHECK_CHARSET_GET_ID):
+ * coding.c (coding_system_charset_list, detect_coding_system):
+ * coding.h (struct coding_system.id):
+ * composite.c (get_composition_id, gstring_lookup_cache):
+ * fns.c (hash_lookup, hash_put, Fgethash, Fputhash):
+ * image.c (xpm_get_color_table_h):
+ * lisp.h (hash_lookup, hash_put):
+ * minibuf.c (Ftest_completion):
+ Use ptrdiff_t for hash table indexes, not int (which is too
+ narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
+ 32-bit --with-wide-int hosts).
+
+ * charset.c (Fdefine_charset_internal): Check for integer overflow.
+ Add a FIXME comment about memory leaks.
+ (syms_of_charset): Don't assume xmalloc returns.
+
+ Don't assume that stated character widths fit in int.
+ * character.c (Fchar_width, c_string_width, lisp_string_width):
+ * character.h (CHAR_WIDTH):
+ * indent.c (MULTIBYTE_BYTES_WIDTH):
+ Use sanitize_char_width to avoid undefined and/or bad behavior
+ with outlandish widths.
+ * character.h (sanitize_tab_width): Renamed from sanitize_width,
+ now that we have two such functions. All uses changed.
+ (sanitize_char_width): New inline function.
+
+ Don't assume that tab-width fits in int.
+ * character.h (sanitize_width): New inline function.
+ (SANE_TAB_WIDTH): New macro.
+ (ASCII_CHAR_WIDTH): Use it.
+ * indent.c (sane_tab_width): Remove. All uses replaced by
+ SANE_TAB_WIDTH (current_buffer).
+ * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
+
+ * fileio.c: Integer overflow issues with file modes.
+ (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
+
+ * charset.c (read_hex): New arg OVERFLOW. All uses changed.
+ Remove unreachable code.
+ (read_hex, load_charset_map_from_file): Check for integer overflow.
+
+ * xterm.c: don't go over XClientMessageEvent limit
+ (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
+ (x_send_scroll_bar_event): Likewise. Check that the size does not
+ exceed limits imposed by XClientMessageEvent, as well as the usual
+ ptrdiff_t and size_t limits.
+
+ * keyboard.c: Overflow, signedness and related fixes.
+ (make_lispy_movement): Use same integer type in forward decl
+ that is used in the definition.
+ (read_key_sequence, keyremap_step):
+ Change bufsize argument back to int, undoing my 2011-03-30 change.
+ We prefer signed types, and int is wide enough here.
+ (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
+ than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
+ larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
+ length, not size_t. Use ptrdiff_t for index, not int.
+ (keyremap_step, read_key_sequence): Redo bufsize check to avoid
+ possibility of integer overflow.
Overflow, signedness and related fixes for images.
(gs_load): Use printmax_t to print the widest integers possible.
Check for integer overflow when computing image height and width.

Integer signedness and overflow and related fixes. (Bug#9079)
Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
well either way, and we prefer signed to unsigned.

+
+ Port to OpenBSD.
+ See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
+ and the surrounding thread.
+ * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
+ rather than fgets, and retry after EINTR. Otherwise, 'emacs
+ --batch -f byte-compile-file' fails on OpenBSD if an inactivity
+ timer goes off.
+ * s/openbsd.h (BROKEN_SIGIO): Define.
+ * unexelf.c (unexec) [__OpenBSD__]:
+ Don't update the .mdebug section of the Alpha COFF symbol table.
+
+2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
+
+ * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
+ (bug#8460).
+
+2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
+ This fixes some race conditions on the permissions of any newly
+ created file.
+
+ * alloc.c (valid_pointer_p): Use pipe, not open.
+ This fixes some permissions issues when debugging.
+
+ * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
+ If fchown fails to set both uid and gid, try to set just gid,
+ as that is sometimes allowed. Adjust the file's mode to eliminate
+ setuid or setgid bits that are inappropriate if fchown fails.
+
+2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
+
+ * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
+ to compare Lisp_Objects.
+ * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
+ global_gnutls_log_level, don't mistake it for a Lisp_Object.
+ (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
+
+2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
+
+ * lread.c (read_integer): Unread even EOF character.
+ (read1): Likewise. Properly record start position of symbol.
+
+ * lread.c (read1): Read `#:' as empty uninterned symbol if no
+ symbol character follows.
+
2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
* fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
