* 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.
* Makefile.in (ACLOCAL_INPUTS): Add all m4/*.m4 files.
* src/Makefile.in (top_srcdir): New var.
(ntsource, lispsource, ALL_CFLAGS, gl-stamp, emacs.res):
Use '$(top_srcdir)' instead of '$(srcdir)/..';
its expansion is a bit shorter.
(../config.status): Actually build config.status instead of
just complaining.
(ACLOCAL_INPUTS, AUTOCONF_INPUTS):
New macros, copied and relocated from ../Makefile.in.
($(top_srcdir)/aclocal.m4, $(top_srcdir)/configure, config.in)
(../config.status, Makefile): New dependencies and rules,
copied with relocation from ../Makefile.in. This should be more
likely to rebuild the build machinery properly if you do a 'make'
in the src directory.
Linux 'sysinfo' function and 'struct sysinfo' type.
* src/alloc.c (Fmemory_info): New function.
* lisp/files.el (warn-maybe-out-of-memory): New function.
(find-file-noselect): Use it.
* Makefile.in (src): No more need to pass BOOTSTRAPEMACS.
* src/Makefile.in (.el.elc): Replace suffix rule with pattern rule.
(%.elc): New pattern rule, with order-only prerequisite.
($(lisp)): No more need to depend on BOOTSTRAPEMACS.
($(lispsource)/loaddefs.el): Use an order-only prerequisite
in place of BOOTSTRAPEMACS.
Fixes: debbugs:2151
* Makefile.in (epaths-force): Don't allow ':' in directories whose
names go into a colon-separated path.
* configure.ac: Fail if submake fails.
Fixes: debbugs:17278
* configure.ac (CFLAGS): With link time optimization,
use -ffat-lto-objects if supported; otherwise Emacs won't
build with GCC 4.9.0.
Fixes: debbugs:17806
* Makefile.in: Use `make -C' rather than `cd && make' throughout.
* lib-src/Makefile.in (../lib/libgnu.a): Use `make -C' rather than `cd && make'.
* lisp/Makefile.in (leim, semantic): Use `make -C' rather than `cd && make'.
* lwlib/Makefile.in ($(globals_h)): Use `make -C' rather than `cd && make'.
* src/Makefile.in: Use `make -C' rather than `cd && make' throughout.
* 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
This fixes a bug with the shell freezing. See:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=17598#185
Merge from gnulib, incorporating:
2014-05-31 dup2, fcntl, fcntl-h: port to AIX 7.1
* lib/fcntl.in.h, m4/dup2.m4, m4/fcntl.m4:
Update from gnulib.
* 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 incorporates:
2014-06-02 acl: apply pure attribute to two functions
2014-06-01 gnulib-common.m4: add _GL_UNUSED_LABEL
2014-05-31 dup2, fcntl, fcntl-h: port to AIX 7.1
2014-05-30 ftoastr: work around compiler bug in IBM xlc 12.1
* lib/acl-internal.h, lib/fcntl.in.h, lib/ftoastr.h:
* m4/dup2.m4, m4/fcntl.m4, m4/gnulib-common.m4:
Update from gnulib.
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.
* .bzrignore: Remove lib-src/ctags.c.
* lib-src/Makefile.in (etags_args): Remove, replacing with ...
(etags_cflags, etags_libs): New macros. All uses changed.
(ctags${EXEEXT}): Don't compile etags.c, as compiling etags.c in
parallel (once for ctags, once for etags) breaks parallel makes
with compilers that use the source file name to name temporaries,
such as Sun C 5.12. Instead, compile ctags.c.
* lib-src/ctags.c: New file.
