+2002-11-02 Stephen J. Turnbull <stephen@xemacs.org>
+
+ * XEmacs 21.4.10 "Military Intelligence" is released.
+
+2002-10-17 Raymond Toy <toy@rtp.ericsson.se>
+
+ * nas.c: Update for NAS 1.6 and later, from Jon Trulson. Was
+ using the NAS private array SoundFileInfo that no longer exists in
+ NAS 1.6 and later. Preserve backward compatibility with NAS 1.5a
+ and earlier. This is broken for some versions between 1.5a and
+ 1.5f.
+
+2002-10-10 Stephen J. Turnbull <stephen@xemacs.org>
+
+ * realpath.c (win32_readlink): Try to fix truename of wildcard bug.
+
+ * emacs.c (shut_down_emacs): Improve crash message.
+
+2002-10-09 Stephen J. Turnbull <stephen@xemacs.org>
+
+ * file-coding.c (determine_real_coding_system): Check for coding
+ cookie in first LINES_TO_CHECK lines (currently 2). Cater to
+ shebangs and Python PEP 263.
+
+2002-10-08 Andy Piper <andy@xemacs.org>
+
+ * glyphs-widget.c (layout_query_geometry): only resize dynamically
+ if static sizes haven't been set.
+
+2002-08-30 Mike Alexander <mta@arbortext.com>
+
+ * event-msw.c (winsock_closer): Use closesocket, not CloseHandle
+ to close a socket.
+
+2002-10-03 Stephen J. Turnbull <stephen@xemacs.org>
+
+ * callproc.c (child_setup): 21.4 doesn't have retry_close.
+
+2002-09-20 Mike Sperber <mike@xemacs.org>
+
+ (This partially gets back my patch from 2002-07-20 without the
+ bug.)
+ * callproc.c (child_setup): Remove Ben's comment noting confusion
+ over the file descriptors >= 3: close_process_descs() doesn't
+ close those. Fix fd range to go up to MAXDESC-1 instead of 64.
+ * process-unix.c (unix_create_process): Call
+ begin_dont_check_for_quit to inhibit unwanted interaction (and
+ thus breaking of X event synchronicity) in the child.
+
+2002-09-26 Golubev I. N. <gin@mo.msk.ru>
+
+ * frame-x.c (x_delete_frame): do not call XtDisplay on a destroyed
+ widget.
+
+2002-08-20 Ben Sigelman <bhsigelm@cs.brown.edu>
+
+ * event-Xt.c (drain_X_queue): loop over while(XEventsQueued())
+ instead of while(XtAppPending()&XtIMXEvent). Upon a gdm logout,
+ the xemacs process did not exit, but looped infinitely here. This
+ fixes that problem.
+
+2002-09-28 Stephen J. Turnbull <stephen@xemacs.org>
+
+ * font-lock.c (SYNTAX_START_STYLE, SYNTAX_END_STYLE): Quiet GCC.
+ (find_context): Improve comments.
+
+ * regex.c (re_compile_fastmap): Gratuitous #ifdef comment fixes.
+ (re_match_2): An XCHAR_TABLE operation was missing.
+
+ Many of the following changes were inspired by Andy Piper's (now
+ obsolete) patch to make syntax-table text property lookup optional.
+
+ [Documentation]
+
+ * syntax.h (top level): Document semantics of syntax flags.
+ * syntax.c (comstr_start, Fforward_comment): Improve comments.
+ * syntax.c, syntax.h (top level): Document syntax cache better in
+ comments.
+
+ [Instrument syntax caching (temporary change)]
+
+ * syntax.h (enum syntax_cache_statistics_functions, struct
+ syntax_cache_statistics, SCS_STATISTICS_SET_FUNCTION,
+ SYNTAX_CACHE_STATISTICS_COUNT_INIT): New types and macros.
+ * syntax.c (scan_words, Fforward_comment, scan_lists,
+ Fbackward_prefix_characters):
+ * font-lock.c (find_context):
+ Use them to instrument syntax caching.
+ * syntax.c (struct syntax_cache_statistics, scs_statistics,
+ syntax_cache_statistics_function_names): New type and variables.
+ * syntax.c (update_syntax_cache): Update and report statistics.
+
+ [Major syntax cache optimizations]
+
+ syntax.c (lookup_syntax_properties): Default off.
+
+ * syntax.h (UPDATE_SYNTAX_INTERNAL): New, implements UPDATE_SYNTAX*.
+ * syntax.c (update_syntax_cache):
+ Move init test from update_syntax_cache to UPDATE_SYNTAX_INTERNAL.
+
+ [Minor syntax cache optimizations and code clarifications]
+
+ * syntax.h (SYNTAX_COMMENT_BITS, SYNTAX_START_P, SYNTAX_END_P,
+ SYNTAX_STYLES_MATCH_START_P, SYNTAX_STYLES_MATCH_1CHAR_P,
+ SYNTAX_STYLES_MATCH_END_P, STYLE_FOUND_1CHAR_P, STYLE_FOUND_P,
+ SYNTAX_COMMENT_MASK_END, SYNTAX_COMMENT_MASK_START,
+ SYNTAX_COMMENT_1CHAR_MASK): Remove redundant argument `table'.
+ (Code clarification.)
+
+ * syntax.c (scan_words, find_end_of_comment, scan_sexps_forward,
+ scan_lists): Compute code from syncode, use Boolean macros instead
+ of redundant masking operations. (Code clarification; any decent
+ compiler can do this optimization.)
+
+ * syntax.c (scan_lists): Rearrange switches (case Sstring_fence)
+ for clarity.
+
+ * syntax.h, syntax.c (NEXT_SINGLE_PROPERTY_CHANGE,
+ PREVIOUS_SINGLE_PROPERTY_CHANGE, update_syntax_cache): Conditionally
+ use F*_single_property_change instead of F*_extent_change.
+ Currently F*_single_property_change is _much_ less efficient.
+
+ * dired.c (Fdirectory_files): Qt not valid in syntax_cache.object.
+ * syntax.h (SETUP_SYNTAX_CACHE_FOR_OBJECT): Initialize
+ syntax_cache.object properly, don't leave Qt or Qnil.
+ (SYNTAX_CACHE_BYTE_TO_CHAR): Use SETUP_SYNTAX_CACHE_FOR_OBJECT.
+ * syntax.c (update_syntax_cache): Use BUFFERP and STRINGP, not
+ tests for Qt or Qnil.
+
+2002-09-21 Stephen J. Turnbull <stephen@xemacs.org>

+
+ * search.c (clear_unused_search_regs): New static function.
+ (search_buffer):
+ (simple_search):

+ Use it. Fixes "stale match data" bug reported by Martin Stjernholm.
+ Minor clarifications in comments.
+
+ * regex.c (re_match_2_internal): Ensure no stale submatches.
+
+2002-09-09 Stephen J. Turnbull <stephen@xemacs.org>
+

+ pixel-based sizing. Does the right thing on character-oriented
+ displays.

+ used as a fallback for both horizontal and vertical justification.
+ (layout_query_geometry): use logical units to size appropriately.
+ (layout_layout): ditto.
+ (Fwidget_logical_to_character_width): new function. Allow users to
+ convert from logical units to characters so that frame sizes can
+ be set appropriately.
