* window.el (display-buffer-in-previous-window): New buffer
display action function.
* emacs-lisp/debug.el (debugger-bury-or-kill): New option.
(debugger-previous-window): New variable.
(debug): Rewrite using display-buffer-in-previous-window,
quit-restore-window and debugger-bury-or-kill. (Bug#8789)
* nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
in the internal border.
(x_set_window_size): Remove static variables and their usage.
(ns_redraw_scroll_bars): Fix NSTRACE arg.
(ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
fringe/internal border adjustment.
(ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
(ns_draw_window_cursor): Remove fringe/internal border adjustment.
(ns_fix_rect_ibw): Remove.
(ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
(ns_dumpglyphs_box_or_relief): Ditto.
(ns_maybe_dumpglyphs_background): Remove fringe/internal border
adjustment.
(ns_dumpglyphs_image): Ditto.
(ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
border adjustment.
(ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
their usage. Add fringe_extended_p and its use as in other terms.
(ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
scroll bar was removed.
(updateFrameSize): New function.
(windowDidResize): Move code to updateFrameSize and call it.

default-directory is remote, create temp file on remote
filesystem.
(python-shell-send-file): When file is remote, pass local view of
file paths to remote Python interpreter. (Bug#12340)
* lisp/subr.el (buffer-narrowed-p): New function.
* lisp/ses.el (ses-widen):
* lisp/simple.el (count-words--buffer-message):
* lisp/net/browse-url.el (browse-url-of-buffer): Use it
* lisp/simple.el (count-words-region): Don't signal an error if there
is a non-nil prefix arg and the mark is not set.
* doc/lispref/positions.texi (Narrowing): Document buffer-narrowed-p.
* configure.ac (FLOAT_CHECK_DOMAIN): Comment fix (Bug#12327).
* src/floatfns.c: Comment fix.
* src/lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
and anyway the declaration is harmless even if SIGDANGER is not defined.
* src/syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
defined BROKEN_FIONREAD). systty.h formerly did this, but other
source files not surprisingly expected syssignal.h to define, or
not define, SIGIO, and it's cleaner to do it that way, for consistency.
Include <sys/ioctl.h>, for FIONREAD.
* src/systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
This eliminates a problem whereby other files mysteriously had
to include "syssignal.h" before including "systty.h" if they
wanted to use "#ifdef SIGIO".
ruby-beginning-of-indent, simplify, allow all keywords to have
indentation before them.
(ruby-beginning-of-indent): Adjust for above. Search until the
found point is not inside a string or comment.
(ruby-font-lock-keywords): Allow symbols to start with "@"
character, give them higher priority than variables.
(ruby-syntax-propertize-function)
(ruby-font-lock-syntactic-keywords): Remove the "not comments"
matchers. Expression expansions are not comments when inside a
string, and there comment syntax status is irrelevant.
(ruby-match-expression-expansion): New function. Check that
expression expansion is inside a string, and it's not escaped.
(ruby-font-lock-keywords): Use it.
* test/automated/ruby-mode-tests.el: New tests (Bug#11613).
The add-face function has been added gnus-compat.el, but is not in
Emacs; this leaves Gnus in an unusable state.
* lisp/gnus/gnus-salt.el (gnus-tree-highlight-node):
* lisp/gnus/gnus-sum.el (gnus-summary-highlight-line):
* lisp/gnus/gnus-group.el (gnus-group-highlight-line): Revert use of add-face.
* lisp/gnus/gnus-util.el (gnus-put-text-property-excluding-characters-with-faces): Restore.
Emacs's signal handlers were written in the old 4.2BSD style with
sigblock and sigmask and so forth, and this led to some
inefficiencies and confusion. Rewrite these to use
pthread_sigmask etc. without copying signal sets around. Also,
get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
'signal', and instead use functions that do not attempt to take
over the system name space. This patch causes Emacs's text
segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
* configure.ac (PTY_OPEN, PTY_TTY_NAME_SPRINTF):
Adjust to syssignal.h changes.
(SIGNAL_H_AB): Remove; no longer needed.
* src/alloc.c, src/emacsgtkfixed.c, src/nsfns.m, src/widget.c, src/xmenu.c:
Do not include <signal.h> or "syssignal.h", as these
modules do not use signals.
* src/atimer.c, src/callproc.c, src/data.c, src/dispnew.c, src/emacs.c:
* src/floatfns.c, src/gtkutil.c, src/keyboard.c, src/process.c, src/sound.c:
* src/sysdep.c, src/term.c, src/xterm.c:
Do not include <signal.h>, as "syssignal.h" does that for us now.
* src/atimer.c (sigmask_atimers): New function.
(block_atimers, unblock_atimers): New functions,
replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
All uses replaced.
* src/conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
no longer needed here.
* src/emacs.c (main): Inspect existing signal handler with sigaction,
so that there's no need to block and unblock SIGHUP.
* src/sysdep.c (struct save_signal): New member 'action', replacing
old member 'handler'.
(save_signal_handlers, restore_signal_handlers):
Use sigaction instead of 'signal' to save and restore.
(get_set_sighandler, set_sighandler) [!WINDOWSNT]:
New function. All users of 'signal' modified to use set_sighandler
if they're writeonly, and to use sys_signal if they're read+write.
(emacs_sigaction_init, forwarded_signal): New functions.
(sys_signal): Remove. All uses replaced by calls to sigaction
and emacs_sigaction_init, or by direct calls to 'signal'.
(sys_sigmask) [!__GNUC__]: Remove; no longer needed.
(sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
all uses replaced by pthread_sigmask etc. calls.
* src/syssignal.h: Include <signal.h>.
(emacs_sigaction_init, forwarded_signal): New decls.
(SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
(SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
(sigmask, sys_sigmask): Remove; no longer needed.
(sigpause): Remove. All uses replaced by its definiens, sigsuspend.
(sigblock, sigunblock, sigfree):
(sigsetmask) [!defined sigsetmask]:
Remove. All uses replaced by pthread_sigmask.
(signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
no longer need to be replaced, and its typical old uses
are now done via emacs_sigaction_init and sigaction.
(sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
(sys_sigdel): Remove; unused.
(NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
Fixes: debbugs:12327
* progmodes/vhdl-mode.el (vhdl-speedbar-initialize): Don't use
obsolete alias speedbar-key-map.
(vhdl-doc-variable, vhdl-doc-mode): Use called-interactively-p.
(vhdl-index-menu-init): Don't use obsolete variable font-lock-maximum-size.
* alloc.c (Fgarbage_collect): Mark buffer_defaults and
mark_local_symbols here.
(mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
since special buffers aren't marked here any more.
(allocate_buffer): Chain new buffer with all_buffers here...
* buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
not here.
(Vbuffer_defaults, Vbuffer_local_symbols): Remove.
(syms_of_buffer): Remove staticpro of the above.
(init_buffer_once): Set names for buffer_defaults and
buffer_local_symbols.
(query-replace, query-replace-regexp, query-replace-regexp-eval)
(replace-string, replace-regexp): Mention it in docstrings.
(perform-replace, replace-highlight): Let-bind
isearch-lax-whitespace and isearch-regexp-lax-whitespace according
to the values of replace-lax-whitespace and regexp-flag.
Don't let-bind search-whitespace-regexp.
* lisp/isearch.el (isearch-query-replace): Let-bind
replace-lax-whitespace instead of let-binding
replace-search-function and replace-re-search-function.
(isearch-lazy-highlight-search): Let-bind isearch-lax-whitespace
and isearch-regexp-lax-whitespace to lazy-highlight variables.
(isearch-toggle-symbol): Set isearch-regexp to nil
in isearch-word mode (like in isearch-toggle-word).
Fixes: debbugs:10885
* lisp/replace.el (replace-search-function)
(replace-re-search-function): Set default values to nil.
(perform-replace): Let-bind isearch-related variables based on
replace-related values, call `isearch-search-fun' and let-bind
the result to `search-function'. Remove code that sets
`search-function' and `search-string' separately for
`delimited-flag'.
(replace-highlight): Add new argument `delimited-flag' and
rename other arguments to the names used in `perform-replace'.
Let-bind `isearch-word' to the argument `delimited-flag'.
* gnus-score.el (gnus-score-decode-text-parts): Use #' for
mm-text-parts used in labels macro to make it work with XEmacs 21.5.
* gnus-util.el (gnus-string-prefix-p): New function, an alias to
string-prefix-p in Emacs >=23.2.
* nnmaildir.el (nnmaildir--ensure-suffix, nnmaildir--add-flag)
(nnmaildir--remove-flag, nnmaildir--scan): Use gnus-string-match-p
instead of string-match-p.
(nnmaildir--scan): Use gnus-string-prefix-p instead of string-prefix-p.

TIME is set.
2012-09-05 Juri Linkov <juri@jurta.org>
* gnus-group.el (gnus-read-ephemeral-bug-group): Allow opening more
than one group at a time (bug#11961).
2012-09-05 Julien Danjou <julien@danjou.info>
* gnus-srvr.el (gnus-server-open-server): Don't message on failure:
this hide the real reason with a message giving absolutely no hint.
2012-09-05 Lars Ingebrigtsen <larsi@gnus.org>
* gnus-group.el (gnus-group-mark-article-read): Propagate the read mark
to the backend (bug#11804).
* message.el (message-insert-newsgroups): Don't insert newsgroup
duplicates (bug#12275).
2012-09-05 John Wiegley <johnw@newartisans.com>
* gnus.el (gnus-expand-group-parameters): Allow regexp substitutions in
sieve rules.
2012-09-05 Jan Tatarik <jan.tatarik@gmail.com>
* gnus-score.el (gnus-score-decode-text-parts): Use #' for the local
function.
* gnus-logic.el (gnus-advanced-body): Allow scoring on decoded bodies.
* gnus-score.el (gnus-score-decode-text-parts): Ditto.
2012-09-05 Magnus Henoch <magnus.henoch@gmail.com>
* nnmaildir.el: Make nnmaildir understand and write maildir flags.
That is, rename files from "unique:2," to "unique:2,S" for "seen", etc.
This should make nnmaildir more usable with offlineimap.
Be more systematic about preserving errno whenever a signal
handler returns, even if it's not in the main thread. Do this by
renaming signal handlers to distinguish between signal delivery
and signal handling. All uses changed.
* atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
* data.c (deliver_arith_signal): Rename from arith_error.
* dispnew.c (deliver_window_change_signal): Rename from
window_change_signal.
* emacs.c (deliver_error_signal): Rename from fatal_error_signal.
(deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
* keyboard.c (deliver_input_available_signal): Rename from
input_available_signal.
(deliver_user_signal): Rename from handle_user_signal.
(deliver_interrupt_signal): Rename from interrupt_signal.
* process.c (deliver_pipe_signal): Rename from send_process_trap.
(deliver_child_signal): Rename from sigchld_handler.
* atimer.c (handle_alarm_signal):
* data.c (handle_arith_signal):
* dispnew.c (handle_window_change_signal):
* emacs.c (handle_fatal_signal, handle_danger_signal):
* keyboard.c (handle_input_available_signal):
* keyboard.c (handle_user_signal, handle_interrupt_signal):
* process.c (handle_pipe_signal, handle_child_signal):
New functions, with the actual signal-handling code taken from the
original respective signal handlers, sans the sporadic attempts to
preserve errno, since that's now done by handle_on_main_thread.
* atimer.c (alarm_signal_handler): Remove unnecessary decl.
* emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
* emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
Move to sysdep.c.
(main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
Move initialization of main_thread to sysdep.c's init_signals.
* process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
our usage, and simplifies the mainline code.
(record_child_status_change): New static function, as a helper
for handle_child_signal, and with most of the old child handler's
contents.
(CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
(handle_child_signal): Use the above.
* sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
Moved here from emacs.c.
(init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
code moved here from emacs.c's main function.
* sysdep.c, syssignal.h (handle_on_main_thread): New function,
replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
lets callers save and restore errno properly.
