* configure.ac (HAVE_TIMERFD): Define only if TFD_CLOEXEC works,
since the code leaked file descriptors to children when !TFD_CLOEXEC.
(HAVE_TIMERFD_CLOEXEC): Remove; no longer used.
* m4/clock_time.m4 (gl_CLOCK_TIME): Don't check for clock_getres.
This reverts the previous change to this file, so it matches
gnulib again.
* src/atimer.c (TIMERFD_CREATE_FLAGS): Remove; we now assume TFD_CLOEXEC.
(alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
Fall back on timer_create if timerfd_create fails at runtime.
(resolution) [HAVE_CLOCK_GETRES]: Remove; we now rely on the
kernel primitives to do resolution. All uses removed.
(timerfd) [!HAVE_TIMERFD]: Define to be -1, for convenience.
(turn_on_atimers): Clear timer_create-based timers too,
for consistency.
* configure.ac (toplevel): Check whether GNU/Linux-specific
timerfd functions and macros are available.
* m4/clock_time.m4 (gl_CLOCK_TIME): Check for clock_getres as well.
* src/atimer.c (toplevel) [HAVE_TIMERFD]: Include sys/timerfd.h.
(toplevel): Rename alarm_timer_ok to special_timer_available.
[HAVE_TIMERFD]: Declare timerfd.
[HAVE_CLOCK_GETRES]: Declare resolution.
(start_atimer) [HAVE_CLOCK_GETRES]: Round up timestamp to
system timer resolution.
(set_alarm) [HAVE_TIMERFD]: Use timerfd_settime.
(timerfd_callback) [HAVE_TIMERFD]: New function.
(atimer_result, debug_timer_callback, Fdebug_timer_check)
[ENABLE_CHECKING]: New function for the sake of automated tests.
(init_atimer) [HAVE_TIMERFD]: Setup timerfd.
[HAVE_CLOCK_GETRES]: Likewise for system timer resolution.
[ENABLE_CHECKING]: Defsubr test function.
* src/atimer.h (timerfd_callback) [HAVE_TIMERFD]: Add prototype.
* src/lisp.h (add_timer_wait_descriptor) [HAVE_TIMERFD]: Likewise.
* src/process.c (add_timer_wait_descriptor) [HAVE_TIMERFD]: New function.
* test/automated/timer-tests.el (timer-tests-debug-timer-check): New test.
Linux 'sysinfo' function and 'struct sysinfo' type.
* src/alloc.c (Fmemory_info): New function.
* lisp/files.el (warn-maybe-out-of-memory): New function.
(find-file-noselect): Use it.
* Makefile.in (epaths-force): Don't allow ':' in directories whose
names go into a colon-separated path.
* configure.ac: Fail if submake fails.
Fixes: debbugs:17278
* configure.ac (CFLAGS): With link time optimization,
use -ffat-lto-objects if supported; otherwise Emacs won't
build with GCC 4.9.0.
Fixes: debbugs:17806
* configure.ac (_REENTRANT): Define on Solaris if HAVE_PTHREAD.
This ports part of the recent AIX fix to Solaris. It is needed
for the same reason that _THREAD_SAFE is needed on AIX, e.g., to
make sure that each thread has its own 'errno'.
Fixes: debbugs:17598
* configure.ac (emacs_check_gnu_make): New shell function.
Use it to avoid duplication when checking for GNU Make.
It's OK for 'configure' to use shell functions these days,
as long as we follow the advice in the 'Shell Functions'
section of the Autoconf manual.
It's never been anything more than pointless complexity
* configure.ac (INFO_EXT, INFO_OPTS): Remove output variables.
* Makefile.in (INFO_EXT): Remove and replace by ".info" throughout.
* doc/emacs/Makefile.in (INFO_EXT): Remove and replace by ".info" throughout.
(INFO_OPTS): Set directly rather than with configure.
* doc/lispintro/Makefile.in (INFO_EXT): Remove and replace by ".info" throughout.
(INFO_OPTS): Set directly rather than with configure.
* doc/lispref/Makefile.in (INFO_EXT): Remove and replace by ".info" throughout.
(INFO_OPTS): Set directly rather than with configure.
* doc/misc/Makefile.in (INFO_EXT): Remove and replace by ".info" throughout.
(INFO_OPTS): Set directly rather than with configure.
* configure.ac (with_xpm_set): New shell var.
(_THREAD_SAFE): Define on AIX if HAVE_PTHREAD.
(with_xpm): Default to 'no' on AIX.
(LIBXPM): Append -lXpm if -lXaw is also used, as the latter
requires the former on AIX.
Fixes: debbugs:17598
* configure.ac (AC_PROG_MAKE_SET): Define a dummy.
(MAKE): Set it to GNU Make, if one can be found.
Search PATH for 'make', 'gmake', 'gnumake'.
This works better on platforms like AIX, where GNU Make
might be in /opt/freeware/bin/make, and reside
behind /usr/bin/make in the PATH.
* nt/inc/ms-w32.h (POLL_FOR_INPUT): Likewise.
* src/keyboard.c, src/process.c: Do not define POLL_FOR_INPUT here
because it will be defined in generated config.h if needed.
configure.ac (C_HEAP_SWITCH): Remove.
src/w32heap.c (DUMPED_HEAP_SIZE): Move from w32heap.h. Don't use
HEAPSIZE; instead, define separate values for the 32- and 64-bit
builds.
src/Makefile.in (C_HEAP_SWITCH): Remove.
(ALL_CFLAGS): Don't use $(C_HEAP_SWITCH).
This doesn't fix Bug#17598, but it does fix a regression since Emacs
built with xlc until recently, and perhaps it'll help us fix Bug#17598.
* configure.ac (GC_SETJMP_WORKS): Define for AIX, too.
Merge from gnulib, incorporating:
2014-05-30 ftoastr: work around compiler bug in IBM xlc 12.1
* lib/ftoastr.c: Update from gnulib.
* src/alloc.c (gdb_make_enums_visible): Remove FLOAT_TO_STRING_BUFSIZE.
* src/conf_post.h (FLEXIBLE_ARRAY_MEMBER) [__IBMC__]: Don't define to empty.
* src/lisp.h (FLOAT_TO_STRING_BUFSIZE): Make it a macro, instead of an enum,
to work around a compiler bug in IBM xlc 12.1.
sigprocmask isn't portable in a multithreaded process.
* configure.ac (gl_THREADLIB): Remove dummy.
Merge from gnulib, incorporating:
2014-05-28 pthread_sigmask, timer-time: use gl_THREADLIB only if needed
* m4/pthread_sigmask.m4, m4/timer_time.m4: Update from gnulib.
* src/Makefile.in (LIB_PTHREAD_SIGMASK): Remove; all uses removed.
Fixes: debbugs:17561
src/Makefile.in (C_HEAP_SWITCH): Get the predefined heap size from
configure.
(ADDSECTION, MINGW_TEMACS_POST_LINK): Remove, no longer used.
src/lisp.h (NONPOINTER_BITS): Modify the condition to define to zero
for MinGW, since it no longer uses gmalloc.
src/buffer.c: Do not define mmap allocations functions for Windows.
Remove mmap_find which is unused. Remove mmap_set_vars which does
nothing useful.
[WINDOWSNT]: Include w32heap.h.
(init_buffer): Always allocate new memory for buffers.
src/emacs.c: Remove mmap_set_vars calls.
src/image.c (free_image): Undef free for Windows because it is
redirected to our private version.
src/unexw32.c (COPY_PROC_CHUNK): Use %p format for 64bits
compatibility.
(copy_executable_and_dump_data): Remove dumping the heap section.
(unexec): Restore using_dynamic_heap after dumping.
src/w32heap.c (dumped_data_commit, malloc_after_dump)
(malloc_before_dump, realloc_after_dump, realloc_before_dump)
(free_after_dump, free_before_dump, mmap_alloc, mmap_realloc)
(mmap_free): New functions.
src/w32heap.h: Declare dumped_data and mmap_* function prototypes.
nt/inc/ms-w32.h: Switch to the system heap allocation scheme
instead of GNU malloc and ralloc.
nt/inc/sys/mman.h: New file.
nt/INSTALL: Update for the new build requirements.
etc/NEWS: Mention build changes on MS-Windows.
configure.ac (C_HEAP_SWITCH) define for different values of
dumped heap size depending on 32/64bits arch on Windows.
Don't check for pthreads.h on MinGW32/64, it gets in the way.
Use mmap(2) for buffers and system malloc for MinGW32/64.
* configure.ac (opsys): On Power Architecture, treat release 7 of
AIX like releases 5 and 6.
* src/unexaix.c (copy_text_and_data): Don't add text_scnptr to ptr
twice. _text already includes this offset.
(unrelocate_symbols): Don't cast 64-bit integer to pointer.
Fixes: debbugs:17540
Also, remove update-game-scores's limits on game scores and
simplify its file-locking code.
* configure.ac (getdelim, getline): Remove.
* lib-src/update-game-score.c (struct score_entry): Unify the username and
data members to a single user_data member, since they don't need to be
changed independently and getdelim and getline aren't helpful.
Make the score member char *, not intmax_t, so that scores are not
limited to intmax_t. All uses changed.
(lose_syserr): A zero errno stands for invalid data in score file.
(normalize_integer): New function.
(main): Use it. Check for invalid scores. Omit redundant stat check.
(read_score): First arg is now a string, not a FILE *. All uses
changed. Do not use getdelim or getline; that's way simpler.
(read_scores): Read the whole file, and let read_score handle each
line.
(score_compare): Compare strings representing integers, not integers.
(write_scores) [DOS_NT]: Eliminate unnecessary chmod.
(lock_file): Simplify locking code, eliminating goto.
Check for unlink failure.
* configure.ac (HAVE_PNG): Port to platforms where libpng-config
succeeds but png.h is absent, by testing libpng-config's output
rather than trusting it. I ran into this problem when building
Emacs trunk on a Solaris 10 host.
* INSTALL: Prefer './configure FOO=BAR' to 'FOO=BAR ./configure'.
* INSTALL.REPO: pkg-config is no longer required to build from
the repository.
* autogen.sh: Don't check for pkg-config.
(progs): Remove pkg-config.
(pkg_config_min, AUTORECONF_ENV, env_space, ACLOCAL_PATH):
Remove. All uses removed.
* m4/pkg.m4: New file, built by admin/merge-pkg-config.
* configure.ac: Remove unnecessary m4_pattern_forbid of ^PKG_ and
an AC_ARG_VAR of PKG_CONFIG_PATH. pkg.m4 does that for us.
(EMACS_CHECK_MODULES): Remove workaround for old pkg-config bug,
as we use pkg.m4 from a newer pkg-config.
* admin/merge-pkg-config: New script.
* admin/notes/copyright: Update for m4/*.m4, in particular m4/pkg.m4.
* etc/NEWS: Prefer './configure FOO=BAR' to 'FOO=BAR ./configure'.
* etc/PROBLEMS (Build-time-problems): Remove pkg-config problem
that is no longer an issue.
* nt/INSTALL: Remove no-longer-needed notes about pkg-config.
* configure.ac (HAVE_XFIXES): Define if available.
(XFIXES_CFLAGS, XFIXES_LIBS): New AC_SUBSTs.
* src/Makefile.in (XFIXES_CFLAGS, XFIXES_LIBS): New var.
* src/xfns.c (x_set_mouse_color): Do not call make_invisible_cursor here.
(make_invisible_cursor): Move to...
* src/xterm.c (make_invisible_cursor): ...here.
(x_probe_xfixes_extension, xfixes_toggle_visible_pointer)
(x_toggle_visible_pointer, x_setup_pointer_blanking): New functions.
(x_term_init): Call to x_setup_pointer_blanking.
(XTtoggle_invisible_pointer): Use blanking specific to this display.
* src/xterm.h (struct x_display_info): New member toggle_visible_pointer.
* configure.ac (EMACS_CHECK_MODULES): Check for failed exit status
of pkg-config, on older pkg-config versions that don't do it
properly.
Fixes: debbugs:17438
Earlier versions are buggy, as pkg-config --libs can output
nothing, which causes xrandr link failures.
* configure.ac (PKG_PROG_PKG_CONFIG): Bump from 0.9.0 to 0.26.
Fixes: debbugs:17438
