Paul Eggert
e752e0b0a2 Use faccessat, not access, when checking file permissions.

* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* admin/merge-gnulib (GNULIB_MODULES): Add faccessat.
(GNULIB_TOOL_FLAGS): Avoid at-internal, fchdir, malloc-posix,
openat-die, openat-h, save-cwd.  Do not avoid fcntl-h.
Omit gnulib's m4/fcntl-o.m4.

* src/fileio.c (Ffile_readable_p):
Use faccessat, not stat + open + close.

* src/xrdb.c (file_p): Use file_directory_p.
* src/lisp.h (file_directory_p): New decl.

stat, as that avoids a permissions race.  When not opening a file,
use file_directory_p rather than stat.
* src/process.c, src/sysdep.c, src/term.c: All uses of '#ifdef O_NONBLOCK'
changed to '#if O_NONBLOCK', to accommodate gnulib O_* tyle.
* src/w32.c (sys_faccessat): Rename from sys_access and switch to
faccessat's API.  All uses changed.

c622b48f78 Improve sys_siglist detection.
* configure.ac (sys_siglist): Look for its decl in <signal.h>.
Otherwise, it's not found in either Fedora 17 or Solaris 11.
* src/sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
defined as a macro, as is done in Solaris.
(sys_siglist_entries): New macro.
(save_strsignal): Use it.
* src/syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.

2b794d6940 Port timers to OpenBSD, plus check for timer failures.
OpenBSD problem reported by Han Boetes.
* profiler.c (setup_cpu_timer): Check for failure of timer_settime
and/or setitimer.
(Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
* syssignal.h (HAVE_ITIMERSPEC): New macro.  This is for platforms
like OpenBSD, which has timer_settime but does not declare it.
OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
whether to use itimerspec-related primitives.  All uses of
HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.

This should fix an OS X build problem reported by Ivan Andrus in
<http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00671.html>.
* admin/merge-gnulib (GNULIB_MODULES): Add timer-time.
* configure.ac (gl_THREADLIB): Define to empty, since Emacs
does threads its own way.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* m4/timer_time.m4: New file, from gnulib.
* src/atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
call timer_settime.

to create 'configure'; problem reported by Andreas Schwab in

* autogen.sh: Exit with status 1 when failing due to missing tools,
reverting the 2012-09-10 change to this file.
* autogen/copy_autogen: Fail if one of the subsidiary actions fail.
Use 'cp -f' for the build-aux files, since the destinations are
typically read-only.

Suggested by Wolfgang Jenker in
<http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00430.html>.
(MAKE_CONFIG_STATUS): Remove.  Remaining use expanded.
This undoes part of the 2012-09-10 patch.
(bootstrap): Run ./configure, rather than trying to run config.status
if it exists.  That builds src/epaths.h more reliably.

eeceac9312 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
The workaround was for improving performance on Solaris 2.4, but
is getting in the way now.  Emacs will still work if someone is
still running Solaris 2.4 in a museum somewhere; Sun dropped
support for Solaris 2.4 in 2003.
* configure.ac (ac_cv_func_vfork_works): Default to 'no' on
Solaris 2.4, so that AC_FUNC_VFORK doesn't think vfork works.
* src/callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
* src/process.c (create_process) [HAVE_WORKING_VFORK]:
Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
since Emacs no longer uses vfork on that platform.

0caaedb1c3 Remove configure's --without-sync-input option.
When auditing signal-handling in preparation for cleaning it up,
I found that SYNC_INPUT has race conditions and would be a real
pain to fix.  Since it's an undocumented and deprecated
configure-time option, now seems like a good time to remove it.
Also see <http://bugs.gnu.org/11080#16>.
* configure.ac (SYNC_INPUT, BROKEN_SA_RESTART): Remove.
* admin/CPP-DEFINES (BROKEN_SA_RESTART, SA_RESTART): Remove.
* etc/TODO (Make SYNC_INPUT the default): Remove, as the code now
behaves as if SYNC_INPUT is always true.
* src/alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
(_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
(alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:

(emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
[!SYSTEM_MALLOC && !SYNC_INPUT]:
Remove. All uses removed.
(MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
implementation, one that depends on whether the new macro
XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
is defined.
* src/atimer.c (run_timers, handle_alarm_signal):
* src/keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
(handle_async_input, process_pending_signals)

* src/eval.c (handling_signal): Remove.  All uses removed.
* src/lisp.h (ELSE_PENDING_SIGNALS): Remove.
All uses replaced with the SYNC_INPUT version.
(reset_malloc_hooks, uninterrupt_malloc, handling_signal):
Remove decls.
* src/sysdep.c, src/syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
Now static.

0328b6de4a Port better to POSIX hosts lacking _setjmp.
* configure.ac (HAVE__SETJMP, HAVE_SIGSETJMP): New symbols.
(_setjmp, _longjmp): Remove.
* src/lisp.h: Include <setjmp.h> here, since we use its symbols here.
All instances of '#include <setjmp.h>' removed, if the
only reason for the instance was because "lisp.h" was included.
(sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
and _longjmp with the new symbols.  Emacs already uses _setjmp if
available, so this change affects only POSIXish hosts that have
sigsetjmp but not _setjmp, such as some versions of Solaris and
Unixware.  (Also, POSIX-2008 marks _setjmp as obsolescent.)
* src/image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
(png_load_body) [HAVE_PNG]:
(PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
(PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
since PNG requires jmp_buf.  This is the only exception to the
general rule that we now use sys_setjmp and sys_longjmp.
This exception is OK since this code does not change the signal
mask or longjmp out of a signal handler.

(PKG_CHECK_MODULES): Capture pkg-config diagnostics

4a4bbad214 Simplify SIGIO usage.
The code that dealt with SIGIO was crufty and confusing, e.g., it
played tricks like "#undef SIGIO" but these tricks were not used
consistently.  Simplify mostly by not #undeffing standard symbols,
e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
or not as we please) rather than "defined SIGIO" (standard symbol
that we probably shouldn't #undef).
* configure.ac (NO_TERMIO, BROKEN_FIONREAD, BROKEN_SIGAIO)
(BROKEN_SIGPOLL, BROKEN_SIGPTY): Remove.
(USABLE_FIONREAD, USABLE_SIGIO): New symbols.  All uses of
'defined SIGIO' replaced with 'defined USABLE_SIGIO', with no need
to #undef SIGIO now (which was error-prone).  Likewise, all uses
of 'defined FIONREAD' replaced with 'defined USABLE_FIONREAD'.
* src/admin/CPP_DEFINES (BROKEN_SIGAIO, BROKEN_SIGIO, BROKEN_SIGPOLL)
(BROKEN_SIGPTY, NO_TERMIO): Remove.
* src/conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
Modules that need it can include it.
[USG5_4 && emacs]: Likewise, do not include the streams stuff here.
* src/dispextern.h (ignore_sigio): New decl.
* src/emacs.c (shut_down_emacs): Invoke unrequest_sigio
unconditionally, since it's now a no-op if !USABLE_SIGIO.
* src/emacs.c (shut_down_emacs):
* src/keyboard.c (kbd_buffer_store_event_hold):
Use ignore_sigio rather than invoking 'signal' directly.
* src/keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
for FIONREAD.
(FIONREAD, SIGIO): Do not #undef.
(tty_read_avail_input): Use #error rather than a syntax error.
* src/process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
for I_PIPE, used by SETUP_SLAVE_PTY.
(DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
* src/sysdep.c (croak): Remove; no longer needed.  This bit of
temporary code, with Fred N. Fish's comment that it's temporary,
has been in Emacs since at least 1992!
(init_sigio, reset_sigio, request_sigio, unrequest_sigio):
Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
* src/syssignal.h (croak): Remove decl.
(SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
* src/systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
now that we're termios-only.
(FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
* src/term.c (dissociate_if_controlling_tty): Use #error rather than
a run-time error.

d673aedc2f * configure.ac: No --with-x-toolkit given: Try gtk3 toolkit first
and then gtk2 if not found.
--with-x-toolkit=gtk|yes: As above, but fail if gtk2 or gt3 not found.
--with-x-toolkit=gtk2: Only try gtk2, fail if not found.
--with-x-toolkit=gtk3: Only try gtk3, fail if not found.

9d9edd4bae 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.

c990426a98 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.
