* subr.el (set-temporary-overlay-map): Add a docstring.  (bug#12346)

Bug #12346 is not closed as this commit does not document
`set-temporary-overlay-map' in the manual.

Discard killed buffers from deleted window and frame objects.

* alloc.c (discard_killed_buffers): New function.
(mark_object): Use it for deleted windows and frames.

gnus-notifications.el: add nil checks

Be more explicit about some Makefile dependencies

* Makefile.in (install-arch-dep, install-arch-indep, install-doc):
Be more explicit about dependencies, for parallel `make install'.

It is not so unreasonable to run `make -j# install' from a clean state
for a self-contained NS build, where the "installation" happens within
the build tree.

Convenient macro to check whether the buffer is live.
* buffer.h (BUFFER_LIVE_P): New macro.
* alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
* minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.

Fix wrong overhang display for gstring compositions (Bug#12364).

overhang of succeeding glyphs overlapping box cursor.

* w32term.c (x_draw_glyph_string): Likewise.

Simplify, document, and port floating-point.

The porting part of this patch fixes bugs on non-IEEE platforms
with frexp, ldexp, logb.
* admin/CPP-DEFINES (HAVE_CBRT, HAVE_LOGB, logb): Remove.
* configure.ac (logb, cbrt): Do not check for these functions,
as they are not being used.
* doc/lispref/numbers.texi (Float Basics, Arithmetic Operations, Math Functions):
Document that / and mod (with floating point arguments), along
with asin, acos, log, log10, expt and sqrt, return special values
instead of signaling exceptions.
(Float Basics): Document that logb operates on the absolute value
of its argument.
(Math Functions): Document that (log ARG BASE) also returns NaN if
BASE is negative.  Document that (expt X Y) returns NaN if X is a
finite negative number and Y a finite non-integer.
* etc/NEWS: Document NaNs versus signaling-error change.
* src/data.c, src/lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
Now static.
* src/floatfns.c: Simplify discussion of functions that Emacs doesn't
support, by removing commented-out code and briefly listing the
C89 functions excluded.  The commented-out stuff was confusing
maintenance, e.g., we thought we needed cbrt but it was commented out.
(logb): Remove decl; no longer needed.
(isfinite): New macro, if not already supplied.
(isnan): Don't replace any existing macro.
(Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
are present on all C89 platforms.
(Ffrexp): Do not special-case zero, as frexp does the right thing
for that case.
(Flogb): Do not use logb, as it doesn't have the desired meaning
on hosts that use non-base-2 floating point.  Instead, stick with
frexp, which is C89 anyway.  Do not pass an infinity or a NaN to
frexp, to avoid getting an unspecified result.

* xdisp.c (Qinhibit_debug_on_message): Now static.

* nsterm.m (ns_update_begin): Set clip path to whole view by using
NSBezierPath.

* lisp/emacs-lisp/benchmark.el (benchmark-run, benchmark-run-compiled):
Use `declare'.
* lisp/gnus/qp.el (quoted-printable-decode-region):

* Makefile.in (Makefile): Mark it as precious, since it's updated
atomically.
(MAKE_CONFIG_STATUS): New macro.
(config.status, bootstrap): Use it.  This causes 'make bootstrap'
to run config.status with the --recheck option, which is more
appropriate for a bootstrap.
(bootstrap): Run autogen.sh right after cleaning.  Don't worry
about failures due to missing tools.
* autogen.sh: Exit with status 101 when failing due to missing tools.

* lisp/eshell/em-unix.el (eshell/sudo): Explicitly drop return value.

Avoid leaving traces of cursor when entering linum-mode.

 src/fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
 left fringe if the window has a left margin.  This avoids leaving
 traces of the cursor because its leftmost pixel is not drawn over.

Fix bug #12277 with incomplete redisplay of the vertical border between windows.

 src/dispnew.c (update_window_line): When the left margin area of a
 screen line is updated, set the redraw_fringe_bitmaps_p flag of
 that screen line.

Assume C89 or later for math functions.

This simplifies the code, and makes it a bit smaller and faster,
and (most important) makes it easier to clean up signal handling
since we can stop worring about floating-point exceptions in
library code.  That was a problem before C89, but the problem
went away many years ago on all practical Emacs targets.
* configure.ac (frexp, fmod): Remove checks for these functions,
as we now assume them.
(FLOAT_CHECK_DOMAIN, HAVE_INVERSE_HYPERBOLIC, NO_MATHERR)

Remove; no longer needed.
* admin/CPP-DEFINES (HAVE_FMOD, HAVE_FREXP, FLOAT_CHECK_DOMAIN)
(HAVE_INVERSE_HYPERBOLIC, NO_MATHERR): Remove.
* src/data.c, src/image.c, src/lread.c, src/print.c:
Don't include <math.h>; no longer needed.
* src/data.c, src/floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
might be autoconfigured, as that never happens.
* src/data.c (fmod):
* src/doprnt.c (DBL_MAX_10_EXP):
* src/print.c (DBL_DIG):
Remove.  C89 or later always defines these.
* src/floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
(in_float, float_error_arg, float_error_arg2, float_error_fn_name)
(arith_error, domain_error, domain_error2):
Remove all this pre-C89 cruft.  Do not include <errno.h> as that's
no longer needed -- we simply return what C returns.  All uses removed.
(IN_FLOAT, IN_FLOAT2): Remove.  All uses replaced with
the wrapped code.
(FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
Remove.  All uses expanded, as these macros are no longer used
more than once and are now more trouble than they're worth.
(Ftan): Use tan, not sin / cos.
(Flogb): Assume C89 frexp.
(fmod_float): Assume C89 fmod.
(matherr) [HAVE_MATHERR]: Remove; no longer needed.

Problem introduced when merging patches.  Noted by Eli Zaretskii in
<http://bugs.gnu.org/12327#67>.

More signal-handler cleanup.

* 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".

* lisp/simple.el (count-words--buffer-message): Fix narrowing check.

MS-Windows followup for 2012-09-07T01:27:44Z!eggert@cs.ucla.edu, signal-handler cleanup.

 src/w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
 src/w32.c (sigemptyset): Empty the set.
 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.

 nt/inc/ms-w32.h (struct sigaction): Declare sa_handler __cdecl.

Fixes: debbugs:12327

Fix compilation failure under ENABLE_CHECKING.

 src/alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.

Fixes: debbugs:12327

* alloc.c (mark_buffer): Revert unsafe marking optimization.
(mark_object): Likewise for frame objects.

* syssignal.h (handle_on_main_thread): Always declare,

even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
This ports to platforms without HAVE_PTHREAD.

* lisp/progmodes/ruby-mode.el
(ruby-beginning-of-defun): Only consider 3 keywords defun beginners.
(ruby-end-of-defun): Expect that the point is at the beginning of
the defun.

Fix for invoking C-h c from the minibuffer.

* help.el (describe-key-briefly): Allow the message to be seen
when invoked from the minibuffer.

Fixes: debbugs:7014

Add a couple of xrefs to the Lisp manual.

* markers.texi (Moving Markers): Add xref to Point.

* syntax.texi (Low-Level Parsing): Add xref to Parser State.

Fixes: debbugs:12269

* lisp/progmodes/ruby-mode.el (ruby-end-of-defun)
(ruby-beginning-of-defun): Simplify, allow indentation before
block beginning and end keywords.  Also, fix accidental change in the former.

* lisp/progmodes/ruby-mode.el (ruby-indent-beg-re): Add pieces from
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).

Partially revert last Gnus merge.

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.

Signal-handler cleanup.

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.
