+
+ * insdel.c, lisp.h (buffer_overflow): New function.
+ (insert_from_buffer_1, replace_range, replace_range_2):
+ * insdel.c (make_gap_larger):
+ * editfns.c (Finsert_char):
+ * fileio.c (Finsert_file_contents): Use it, to normalize wording.
+
+ * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
+
+2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ Integer overflow and signedness fixes (Bug#8873).
+
+ * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
+ (GET_CCL_RANGE, IN_INT_RANGE): Use it.
+
+ * fileio.c: Don't assume EMACS_INT fits in off_t.
+ (emacs_lseek): New static function.
+ (Finsert_file_contents, Fwrite_region): Use it.
+ Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
+
+ * fns.c (Fload_average): Don't assume 100 * load average fits in int.
+
+ * fns.c: Don't overflow int when computing a list length.
+ * fns.c (QUIT_COUNT_HEURISTIC): New constant.
+ (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
+ truncation on 64-bit hosts. Check for QUIT every
+ QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
+ faster and is responsive enough.
+ (Flength): Report an error instead of overflowing an integer.
+ (Fsafe_length): Return a float if the value is not representable
+ as a fixnum. This shouldn't happen except in contrived situations.
+ (Fnthcdr, Fsort): Don't assume list length fits in int.
+ (Fcopy_sequence): Don't assume vector length fits in int.
+
+ * alloc.c: Check that resized vectors' lengths fit in fixnums.
+ (header_size, word_size): New constants.
+ (allocate_vectorlike): Don't check size overflow here.
+ (allocate_vector): Check it here instead, since this is the only
+ caller of allocate_vectorlike that could cause overflow.
+ Check that the new vector's length is representable as a fixnum.
+
+ * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
+ The previous code was bogus. For example, next_almost_prime (32)
+ returned 39, which is undesirable as it is a multiple of 3; and
+ next_almost_prime (24) returned 25, which is a multiple of 5 so
+ why was the code bothering to check for multiples of 7?
+
+ * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
+
+ * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
+
+ Variadic C functions now count arguments with ptrdiff_t.
+ This partly undoes my 2011-03-30 change, which replaced int with size_t.
+ Back then I didn't know that the Emacs coding style prefers signed int.
+ Also, in the meantime I found a few more instances where arguments
+ were being counted with int, which may truncate counts on 64-bit
+ machines, or EMACS_INT, which may be unnecessarily wide.
+ * lisp.h (struct Lisp_Subr.function.aMANY)
+ (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
+ Arg counts are now ptrdiff_t, not size_t.
+ All variadic functions and their callers changed accordingly.
+ (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
+ * bytecode.c (exec_byte_code): Check maxdepth for overflow,
+ to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
+ * callint.c (Fcall_interactively): Check arg count for overflow,
+ to avoid potential buffer overrun. Use signed char, not 'int',
+ for 'varies' array, so that we needn't bother to check its size
+ calculation for overflow.
+ * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
+ * eval.c (apply_lambda):
+ * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
+ (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
+ (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
* callint.c (Fcall_interactively): Don't use index var as event count.
* vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
* mem-limits.h (SIZE): Remove; no longer used.

-
* xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
Remove unnecessary casts.
* alloc.c (Fmake_string): Check for out-of-range init.
+2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
+
+ * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
+
+2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
+
+ * xfns.c (x_set_scroll_bar_default_width): Remove argument to
+ xg_get_default_scrollbar_width.
+
+ * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
+ (int_gtk_range_get_value): Move to the scroll bar part of the file.
+ (style_changed_cb): Call update_theme_scrollbar_width and call
+ x_set_scroll_bar_default_width and xg_frame_set_char_size for
+ all frames (Bug#8505).
+ (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
+ Call gtk_window_set_resizable if HAVE_GTK3.
+ (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
+ and height if HAVE_GTK3 (Bug#8505).
+ (scroll_bar_width_for_theme): New variable.
+ (update_theme_scrollbar_width): New function.
+ (xg_get_default_scrollbar_width): Move code to
+ update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
+ (xg_initialize): Call update_theme_scrollbar_width.
+
+ * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
+
+ * emacsgtkfixed.c, emacsgtkfixed.h: New files.
