Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
This incorporates:
2017-08-15 renameat: ensure declaration in <stdio.h> on NetBSD
2017-08-15 extensions: enable NetBSD specific extensions
2017-08-14 open: support O_CLOEXEC

For the motivation behind this patch, please see Bug#28023 and:
http://emacshorrors.com/posts/make-temp-name.html
Although, given the recent changes to Tramp, the related security
problem in make-temp-file is already fixed, make-temp-file still has
several unnecessary system calls. In the typical case on GNU/Linux,
this patch replaces 8 syscalls (symlink, open, close, readlinkat, uname,
getpid, unlink, umask) by 2 (open, close).

* m4/utimes.m4: Copy from gnulib.
The NetBSD library supports localtime_rz directly, and without
this change 'configure' omitted the flexmember test that is marked
as conditional on localtime_rz. Emacs now needs to use
flexmember.m4 even when localtime_rz works.
Problem reported by Thomas Klausner.
* admin/merge-gnulib (GNULIB_MODULES): Add flexmember.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
This removes a workaround where Emacs did not use flexible
array members when compiled with IBM XL C. Instead, avoid
the problem by making the aliasing issues more obvious to
this compiler.
* admin/merge-gnulib: Don’t remove m4/flexmember.m4.
* m4/flexmember.m4: Copy from gnulib.
* configure.ac (AC_C_FLEXIBLE_ARRAY_MEMBER): Remove workaround.
* src/alloc.c (allocate_string_data): Rephrase to avoid aliasing
problem that would otherwise mess up code generated for flexible
array members by IBM XL C for AIX, V12.1.
* src/conf_post.h (FLEXIBLE_ARRAY_MEMBER): Remove; now done
by gnulib code.
This incorporates:

* admin/merge-gnulib (GNULIB_TOOL_FLAGS): Don’t avoid flexmember,
since time_rz now uses part of it. Instead, remove m4/flexmember.m4.
* configure.ac (AC_C_FLEXIBLE_ARRAY_MEMBER): Define away,
since Emacs assumes C99 and therefore removes m4/flexmember.m4.

The OpenBSD C compiler issues false alarms about strcpy, strcat, and
sprintf, and this messes up 'configure' when it tests for the cleanup
attribute. Work around the problem by using __has_attribute directly.
Problem reported by Joakim Jalap (Bug#22385).

* m4/ax_gcc_var_attribute.m4: Remove.
* src/conf_post.h (__has_attribute): Provide a substitute, for
non-GCC or older GCC compilers. All uses changed to assume
the substitute. Check for the cleanup attribute.
* src/emacs-module.c (module_has_cleanup): Just use __has_attribute.
* admin/merge-gnulib (GNULIB_MODULES): Add ignore-value.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/ignore-value.h: New file, from gnulib.

and avoid fflush when handling signals.
* configure.ac: Add '--with-modules' option. Conditionally add
dynlib.o and module.o to the list of objects. Add any system
specific flags to the linker flags to support dynamic libraries.
* m4/ax_gcc_var_attribute.m4: Add autoconf extension to test gcc
attributes.

This attempts to repair problems introduced by the bad merge
5491fd1098. The easiest way for me

It's not safe to call qsort or qsort_r, since they have undefined
behavior if the user-specified predicate is not a total order.
Also, watch out for garbage-collection while sorting vectors.

since the code leaked file descriptors to children when !TFD_CLOEXEC.
(HAVE_TIMERFD_CLOEXEC): Remove; no longer used.

This reverts the previous change to this file, so it matches

(alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
Fall back on timer_create if timerfd_create fails at runtime.

2013-10-18 extern-inline: make safe for -Wundef usage
2013-09-30 fpending: use pure+const function attrs
* lib/fpending.h, m4/acl.m4, m4/extern-inline.m4: Update from gnulib.
This incorporates:
2013-10-10 strtoumax: port to Solaris 8
2013-10-09 strtoimax, strtoumax: port to HP-UX 11.11
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/inttypes.in.h, lib/strtoimax.c, m4/inttypes.m4, m4/strtoimax.m4:
* m4/strtoumax.m4:
Update from gnulib.
Do this by using the Gnulib modules for this.
This should generate faster code on non-GCC, non-MSC platforms,
and make the code a bit more portable, at least in theory.
* admin/merge-gnulib (GNULIB_MODULES): Add count-one-bits
and count-trailing-zeros.
* lib/count-one-bits.c, lib/count-one-bits.h:

* src/data.c: Include <count-one-bits.h>, <count-trailing-zeros.h>.
(USE_MSC_POPCOUNT, POPCOUNT_STATIC_INLINE)
(NEED_GENERIC_POPCOUNT, popcount_size_t_generic)
(popcount_size_t_msc, popcount_size_t_gcc):
Remove; now done by Gnulib.
(popcount_size_t): Now a macro that defers to Gnulib.
(count_trailing_zero_bits): Return int, for consistency with
Gnulib and because Emacs prefers signed to unsigned int.
Don't assume that size_t is either unsigned int or unsigned long
or unsigned long long.
(size_t_to_host_endian): Do not assume that size_t is either
exactly 32 or exactly 64 bits wide.
* src/lisp.h (BITS_PER_SIZE_T): Define consistently with BITS_PER_LONG
etc., so that it's now an enum constant, not a macro.
No need to assume that it's either 32 or 64.
Fixes: debbugs:15550
* src/conf_post.h (__has_builtin, assume): Remove; gnulib now does these.
* src/lisp.h: Include <verify.h>, for 'assume'.
This also incorpoprates:
2013-10-02 verify: new macro 'assume'
2013-09-26 dup2, dup3: work around another cygwin crasher
2013-09-26 getdtablesize: work around cygwin issue
This incorporates:
2013-09-24 manywarnings: enable nicer gcc warning messages
2013-09-23 warnings: port --enable-gcc-warnings to Solaris Studio 12.3
2013-09-21 timespec: use the new TIMESPEC_RESOLUTION elsewhere
* configure.ac (WERROR_CFLAGS): Omit -fdiagnostics-show-option
and -funit-at-a-time, since manywarnings does that for us now.
This incorporates the following changes:
2013-09-19 stdio: OS X port of putc_unlocked + extern inline
2013-09-19 signal: OS X port of sigaddset etc. + extern inline
2013-09-19 extern-inline: do not always suppress extern inline on OS X
2013-09-17 getgroups: statement without effect
2013-08-28 headers: check that _GL_INLINE_HEADER_BEGIN is defined
Gnulib's emulation of mkostemp doesn't have races that Emacs's does.
* configure.ac (mkostemp): Remove check for this function;
gnulib does the check now.
(mkstemp): Remove check for this no-longer-used function.
* lib/mkostemp.c, lib/secure_getenv.c, lib/tempname.c, lib/tempname.h:
* m4/mkostemp.m4, m4/secure_getenv.m4, m4/tempname.m4:
New files, copied from Gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* admin/merge-gnulib (GNULIB_MODULES): Add mkostemp.
* lib-src/movemail.c (main):
* lib-src/update-game-score.c (write_scores):
Use mkostemp (which now works on all platforms, due to changes
in the portability layer) rather than mktemp (which has a race)
or mkstemp (which we no longer bother with).
* src/callproc.c (create_temp_file):
* src/filelock.c (create_lock_file):
Assume mkostemp, since it's now provided by Gnulib.
Fixes: debbugs:15015
* lib/binary-io.c, lib/binary-io.h: New files.
Merge from gnulib, incorporating:
2013-07-09 accept4, dup3, pipe2: port to Cygwin
* lib/pipe2.c: Update from gnulib, as part of this merge.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
Fixes: debbugs:14821

* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* admin/merge-gnulib (GNULIB_MODULES): Remove ignore-value.
* src/callproc.c (child_setup) [!DOS_NT]: Don't try to stuff an error
number into an exit status. Instead, use EXIT_CANCELED.
(child_setup) [!MSDOS]: Avoid possible deadlock with vfork.
* src/callproc.c (relocate_fd):
* src/emacs.c (close_output_streams, main):
* src/process.c (create_process):
* src/sysdep.c (sys_subshell) [!DOS_NT || !WINDOWSNT]:
Use emacs_perror for simplicity.
* src/callproc.c (relocate_fd, main):
* src/sysdep.c (sys_subshell):
Exit with EXIT_CANCELED etc., not 1, when exec setup fails.
(shut_down_emacs): Use emacs_write, not write.
* src/emacs.c, src/sysdep.c: Don't include <ignore-value.h>.
* src/fileio.c (Fcopy_file, e_write):
* src/nsterm.m (ns_select):
* src/process.c (send_process):
* src/sound.c (vox_write):
Use emacs_write_sig, not emacs_write.

* src/process.h (EXIT_CANCELED), EXIT_CANNOT_INVOKE, EXIT_ENOENT):
New constants.
* src/sysdep.c (emacs_backtrace): Use emacs_write, not ignore_value
of write.
(emacs_full_write): New function.
(emacs_write): Rewrite to use it.
(emacswrite_sig, emacs_perror): New functions.
* src/xrdb.c (fatal): Don't invoke perror, since errno might be garbage.
This simplifies Emacs a bit, since it no longer needs to worry
about closing file descriptors by hand in some cases.
It also fixes some unlikely races. Not all such races, as
libraries often open files internally without setting
close-on-exec, but it's an improvement.
* admin/merge-gnulib (GNULIB_MODULES): Add fcntl, pipe2.
(GNULIB_TOOL_FLAGS): Avoid binary-io, close. Do not avoid fcntl.
* configure.ac (mkostemp): New function to check for.

* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* nt/gnulib.mk: Remove empty gl_GNULIB_ENABLED_verify section;
otherwise, gnulib-tool complains given close-on-exec changes.
* nt/inc/ms-w32.h (pipe): Remove.
* nt/mingw-cfg.site (ac_cv_func_fcntl, gl_cv_func_fcntl_f_dupfd_cloexec)

Use 'pipe2' with O_CLOEXEC instead of 'pipe'.
* src/emacs.c (Fcall_process_region) [HAVE_MKOSTEMP]:
* src/filelock.c (create_lock_file) [HAVE_MKOSTEMP]:
Prefer mkostemp with O_CLOEXEC to mkstemp.
* src/callproc.c (relocate_fd) [!WINDOWSNT]:
* src/emacs.c (main): Use F_DUPFD_CLOEXEC, not plain F_DUPFD.
No need to use fcntl (..., F_SETFD, FD_CLOEXEC), since we're
now using pipe2.
* src/filelock.c (create_lock_file) [! HAVE_MKOSTEMP]:
Make the resulting file descriptor close-on-exec.
* src/lisp.h, src/lread.c, src/process.c (close_load_descs, close_process_descs):
* src/lread.c (load_descriptor_list, load_descriptor_unwind):
Remove; no longer needed. All uses removed.
* src/process.c (SOCK_CLOEXEC): Define to 0 if not supplied by system.
(close_on_exec, accept4, process_socket) [!SOCK_CLOEXEC]:
New functions.
(socket) [!SOCK_CLOEXEC]: Supply a substitute.
(Fmake_network_process, Fnetwork_interface_list):
(Fnetwork_interface_info, server_accept_connection):
Make newly-created socket close-on-exec.
* src/sysdep.c (emacs_open, emacs_fopen):
Make new-created descriptor close-on-exec.
* src/w32.c (fcntl): Support F_DUPFD_CLOEXEC well enough for Emacs.
* src/w32.c, src/w32.h (pipe2): Rename from 'pipe', with new flags arg.

2013-05-15 stdio: use __REDIRECT for fwrite, fwrite_unlocked
2013-05-15 sig2str, stdio, warnings: port to clang
* configure.ac: Remove -with-acl option, since Gnulib does that for
us now.
(LIBACL_LIBS): Remove; no longer needed.

for the benefit of the new ACL implementation.
* lib/makefile.w32-in (GNULIBOBJS): Add $(BLD)/acl-errno-valid.$(O).
($(BLD)/acl-errno-valid.$(O)): New rule.

* admin/merge-gnulib (GNULIB_MODULES): Add qacl.
(GNULIB_TOOL_FLAGS): Do not avoid errno.
* etc/NEWS: Emacs is no longer limited to POSIX ACLs. --disable-acl,
not --without-acl, since we're now using Gnulib's implementation.
* nt/config.nt (HAVE_ACL_SET_FILE): Rename from HAVE_POSIX_ACL.
* nt/inc/ms-w32.h (EOPNOTSUPP): New macro.
* src/Makefile.in (LIB_ACL): New macro.
(LIBACL_LIBS): Remove.
(LIBES): Use LIB_ACL, not LIBACL_LIBS.
* src/fileio.c: Include <acl.h>.
Use HAVE_ACL_SET_FILE rather than HAVE_POSIX_ACL.
(ACL_NOT_WELL_SUPPORTED): Remove. All uses replaced by
!acl_errno_valid.
(Fcopy_file) [!WINDOWSNT]: Use qcopy_acl instead of rolling
it ourselves.

* lib-src/Makefile.in (LIB_FDATASYNC): New macro.
(emacsclient${EXEEXT}): Use it.
* lib-src/emacsclient.c (main): Use fdatasync, not fsync, since we don't
care about metadata. Keep trying if interrupted.
* lib-src/movemail.c (main, popmail): Don't worry about BSD_SYSTEM, since
fsync is available everywhere (or there is a substitute). Don't
report an error if fsync returns EINVAL.

Don't worry about HAVE_FSYNC, since a substitute fsync is
available if the system lacks one.
(Fwrite_regin): Retry fsync if interrupted.

This incorporates:
2013-03-12 mktime: fix configure typo
2013-03-11 regex: port to mingw's recent addition of undeclared alarm
2013-03-11 putenv: avoid compilation warning on mingw
2013-03-11 unistd: don't prevent Tru64 Unix from using gnulib strtod.
2013-02-21 putenv: port better to native Windows
2013-02-18 extern-inline: avoid compilation error with HP-UX cc
2013-02-14 putenv: fix heap corruption with mixed putenv/_putenv
On my host, this speeds up directory-files-and-attributes by a
factor of 3, when applied to Emacs's src directory.
These functions are standardized by POSIX and are common these
days; fall back on a (slower) gnulib implementation if the host
is too old to supply them.
* .bzrignore: Add lib/dirent.h.
* lib/Makefile.am (libgnu_a_SOURCES): Add openat-die.c, save-cwd.c.
* lib/careadlinkat.c, lib/careadlinkat.h: Merge from gnulib,
incorporating: 2013-01-29 careadlinkat: do not provide careadlinkatcwd.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.

* m4/fstatat.m4: New files, from gnulib.
* lib/openat-die.c, lib/save-cwd.c, lib/save-cwd.h: New files.
These last three are specific to Emacs and are not copied from gnulib.
They are simpler than the gnulib versions and are tuned for Emacs.
* admin/merge-gnulib (GNULIB_MODULES): Add fdopendir, fstatat, readlinkat.
(GNULIB_TOOL_FLAGS): Do not avoid at-internal, openat-h.
Avoid dup, open, opendir.

* src/conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
* src/dired.c: Include <fcntl.h>.
(open_directory): New function, which uses open and fdopendir
rather than opendir. DOS_NT platforms still use opendir, though.
(directory_files_internal, file_name_completion): Use it.
(file_attributes): New function, with most of the old Ffile_attributes.
(directory_files_internal, Ffile_attributes): Use it.
(file_attributes, file_name_completion_stat): First arg is now fd,
not dir name. All uses changed. Use fstatat rather than lstat +
stat.
(file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
* src/fileio.c: Include <allocator.h>, <careadlinkat.h>.
(emacs_readlinkat): New function, with much of the old
Ffile_symlink_p, but with an fd argument for speed.
It uses readlinkat rather than careadlinkatcwd, so that it
need not assume the working directory.
(Ffile_symlink_p): Use it.
* src/filelock.c (current_lock_owner): Use emacs_readlinkat
rather than emacs_readlink.
* src/lisp.h (emacs_readlinkat): New decl.
(READLINK_BUFSIZE, emacs_readlink): Remove.
* src/sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
(emacs_norealloc_allocator, emacs_readlink): Remove.
This stuff is moved to fileio.c.
* src/w32.c (fstatat, readlinkat): New functions.
(careadlinkat): Don't check that fd == AT_FDCWD.
(careadlinkatcwd): Remove; no longer needed.
Fixes: debbugs:13539
* admin/merge-gnulib (GNULIB_MODULES): Add putenv, unsetenv.

(tzvalbuf_in_environ): New static var.
(init_editfns): Initialize these two static vars.
(Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
Save old TZ value on stack, if it's small.
(Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
instead, use xputenv+unsetenv to set and restore TZ.
(environbuf): Remove static var. All uses removed.
(Fset_time_zone_rule): Do not save TZ and environ;
no longer needed here.
(set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
Move to inside set_time_zone_rule; they don't need file scope any more.
(set_time_zone_rule): Maintain the TZ=value string separately.
(syms_of_editfns): Don't initialize initial_tz;
init_editfns now does it.
* src/emacs.c (dump_tz) [HAVE_TZSET]: Now const.
* src/lisp.h (xputenv): New decl.

(init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.

All uses replaced by 'kill' with a negative pid.
(SIGCHLD): Remove definition, as we now assume SIGCHLD.
* src/w32proc.c (sys_kill): Support negative pids compatibly with POSIX.

This fixes a bug that has been present in Emacs since its creation.
It was reported by Chris Torek in 1983 even before GNU Emacs existed,
which must set some sort of record. (Torek's bug report was against
a predecessor of GNU Emacs, but GNU Emacs happened to have the
same common flaw.) See Torek's Usenet posting
"setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858

* src/fileio.c (check_existing, check_executable, check_writable)
(Ffile_readable_p):
Use symbolic names instead of integers for the flags, as they're
portable now.
(check_writable): New arg AMODE. All uses changed.
Set errno on failure.
(Ffile_readable_p): Use faccessat, not stat + open + close.
(Ffile_writable_p): No need to call check_existing + check_writable.
Just call check_writable and then look at errno. This saves a syscall.
dir should never be nil; replace an unnecessary runtime check
with an eassert. When checking the parent directory of a nonexistent
file, check that the directory is searchable as well as writable, as
we can't create files in unsearchable directories.
(file_directory_p): New function, which uses 'stat' on most platforms
but faccessat with D_OK (for efficiency) if WINDOWSNT.
(Ffile_directory_p, Fset_file_times): Use it.
(file_accessible_directory_p): New function, which uses a single
syscall for efficiency.
(Ffile_accessible_directory_p): Use it.

* src/lisp.h (file_directory_p, file_accessible_directory_p): New decls.

stat, as that avoids a permissions race. When not opening a file,
use file_directory_p rather than stat.
(dir_warning): First arg is now a usage string, not a format.
Use errno. All uses changed.
* src/nsterm.m (ns_term_init): Remove unnecessary call to file-readable
that merely introduced a race.
* src/process.c, src/sysdep.c, src/term.c: All uses of '#ifdef O_NONBLOCK'
changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
and similarly for the other O_* flags.
* src/w32.c (sys_faccessat): Rename from sys_access and switch to
faccessat's API. All uses changed.
* src/xrdb.c: Do not include <sys/stat.h>; no longer needed.
(magic_db): Rename from magic_file_p.
(magic_db, search_magic_path): Return an XrmDatabase rather than a
char *, so that we don't have to test for file existence
separately from opening the file for reading. This removes a race
fixes a permission-checking problem, and simplifies the code.
All uses changed.
(file_p): Remove; no longer needed.

* 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.
Merge from gnulib, incorporating:
2012-08-24 execinfo: port to FreeBSD
2012-08-22 execinfo: new module
* admin/merge-gnulib (GNULIB_MODULES): Add execinfo.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/execinfo.c, lib/execinfo.in.h, m4/execinfo.m4: New files.

(die) [ENABLE_CHECKING]: Print a backtrace if available.
* src/Makefile.in (LIB_EXECINFO): New macro.
(LIBES): Use it.
2012-08-01 extern-inline: new module
2012-08-01 stat-time, timespec, u64, utimens: use extern-inline
* lib/stat-time.c, lib/utimespec.c, lib/u64.c, m4/extern-inline.m4:
New files. The new .c files are for instantiating extern inline
functions.
Fixes: debbugs:12116
* .bzrignore: Add lib/stdalign.h.
* config.bat: Do not set NO_DECL_ALIGN; no longer needed.
Copy lib/stdalign.in.h to lib/stdalign.in-h as needed.
* configure.ac (HAVE_ATTRIBUTE_ALIGNED): Remove the code that
fiddles with this, as gnulib now does this for us.
* admin/merge-gnulib: Add environ, stdalign.
* m4/environ.m4: New file, from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.

* src/lisp.h: Include <stdalign.h>.
(GCALIGNMENT): New macro and constant.
(DECL_ALIGN): Remove. All uses replaced by alignas (GCALIGNMENT).
(USE_LSB_TAG): ifdef on alignas, not on DECL_ALIGN.
(stdalign): New macro, if not already defined.
Merge from gnulib to make "#define unix" unnecessary, incorporating:
2012-07-10 getloadavg: clean out old Emacs and Autoconf cruft
2012-07-09 getopt: Simplify after Emacs changed.
* src/s/aix4-2.h (unix): Remove; no longer needed.
* configure.in (INSTALL_INFO): Set it with one call to
AC_PATH_PROG, not three.
(PKG_CONFIG): Hoist this out of PKG_CHECK_MODULES, since it's
so likely that it'll be needed.
(AC_CHECK_HEADERS_ONCE): Prefer to AC_CHECK_HEADERS where either works.
(AC_PROG_MAKE_SET): Remove; Automake does this.
(sysinfo): Do not check for this function, as it's never used.
(tzset): Check for this function just once.
* admin/CPP-DEFINES: Remove HAVE_SYSINFO.
* m4/manywarnings.m4: Sync from gnulib, incorporating the following:
2012-05-27 manywarnings: remove duplicate -Wmultichar entry
Previously the file was named m4/gl-comp.m4 due to DOS 8+3 restrictions,
even though the file's name in gnulib is m4/gnulib-comp.m4.
This had a problem when merging from gnulib, as the code temporarily
renamed it to the full name, causing problems when interrupted.
Now the file has its full name, with the idea that we will find
a solution for MS-DOS that does not affect the rest of Emacs.
* m4/gnulib-comp.m4: Rename from m4/gl-comp.m4.
* admin/merge-gnulib: Leave m4/gnulib-comp.m4's name alone.
dated 2011-10-07. Regenerating from current gnulib would be a
pervasive change, and currently the trunk isn't open to such changes.
* configure.in (WARN_CFLAGS): Remove; no longer needed now
that gnulib does it.
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
I have been using this change for many months in my private copy
of Emacs, and have used it to find several bugs. It's mature
enough to publish now.
* Makefile.in (GNULIB_MODULES): Add warnings, manywarnings.
* configure.in: Support --enable-gcc-warnings, in the style of
other GNU packages such as coreutils.
(C_WARNINGS_SWITCH): Remove, replacing with...
(WARN_CFLAGS, GNULIB_WARN_CFLAGS): New variable.
(PKG_CHECK_MODULES, C_SWITCH_X_SITE): Use -isystem rather than -I,
when including system files with GCC.
* etc/NEWS: Mention --enable-gcc-warnings.
* lib/Makefile.am (AM_CFLAGS): New macro.
* m4/manywarnings.m4, m4/warnings.m4: New files, from gnulib.
* lib-src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(BASE_CFLAGS): Use new macros rather than old.
* lwlib/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* oldXMenu/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
* src/regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
-Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
-Wunused-result, -Wunused-variable. This should go away once
the Emacs and Gnulib regex code is merged.
(xmalloc, xrealloc): Now static.
Bug reported by Chong Yidong for SunOS 5.10 Generic_127111-11 sparc.
I cannot reproduce it on SunOS 5.10 Generic_141444-09 sparc but
possibly this is because Sun fixed the 'stat' bug in my version.
* Makefile.in (GNULIB_TOOL_FLAGS): Do not avoid the pathmax module.
* lib/pathmax.h, m4/pathmax.m4: New files, from gnulib.
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
These changes are based on gnulib version
4f11d6bebc3098c64ffde27079ab0d0cecfd0cdc dated 2011-10-07 20:59:10,
because Emacs is in feature freeze and we do not want to merge any
more-recent changes from gnulib.
* lib/signal.in.h, lib/sigprocmask.c, m4/gl-comp.m4:
* m4/gnulib-common.m4: Merge from gnulib.
Without this, 'configure' would say "func_gl_gnulib_m4code_pathmax:
command not found" on powerpc-apple-darwin9.8.0.
This clarifies and fixes some licensing issues raised by Glenn Morris
<http://lists.gnu.org/archive/html/bug-gnulib/2011-09/msg00397.html>.
It also merges the latest version of texinfo.tex and has some
MSVC-related changes that don't affect Emacs.
* Makefile.in (GNULIB_TOOL_FLAGS): Avoid msvc-inval, msvc-nothrow,
pathmax, and raise, since these are needed only to address
MSVC-related issues that Emacs doesn't have.
* doc/misc/texinfo.tex, lib/dup2.c, lib/gnulib.mk, lib/signal.in.h:
* lib/sigprocmask.c, lib/stat.c, lib/stdio.in.h, lib/sys_stat.in.h:
* lib/unistd.in.h, m4/dup2.m4, m4/getloadavg.m4, m4/gl-comp.m4:
* m4/include_next.m4, m4/signal_h.m4, m4/signalblocking.m4:
* m4/stdint.m4, m4/stdio_h.m4, m4/sys_stat_h.m4, m4/time_h.m4:
* m4/unistd_h.m4: Merge from gnulib.
* lib/lstat.c, lib/stat.c, m4/include_next.m4, m4/nocrash.m4:
* m4/signal_h.m4, m4/time_h.m4, m4/unistd_h.m4:
Merge from gnulib. This fixes a compilation error on Tru64 UNIX
aka OSF/1 5.1 DTK cc. There is also some mingw stuff here that
doesn't affect Emacs.
* m4/largefile.m4: New file, so that Emacs does not mess up when
accessing files with large inode numbers in MacOS X 10.5 and later.
* m4/nocrash.m4: New file, to avoid triggering background debugger
and/or create core dumps during 'configure'.
* build-aux/move-if-change: Renamed from move-if-change.
* build-aux/snippet/arg-nonnull.h: Renamed from arg-nonnull.h.
* build-aux/snippet/c++defs.h: Renamed from c++defs.h.
* build-aux/snippet/warn-on-use.h: Renamed from warn-on-use.h.
* build-aux/snippet/_Noreturn.h: New file, for draft C1X _Noreturn.
* .bzrignore: The autogenerated files compile, config.guess,
config.sub, depcomp, install-sh, and missing are now in build-aux.
* Makefile.in (epaths-force, sync-from-gnulib):
move-if-change is now in build-aux.
(GNULIB_TOOL_FLAGS): Avoid threadlib; this is now a prerequisite
of gnulib's pthread_sigmask module, but Emacs doesn't need it.
(mkdir): install-sh is now in build-aux.
* config.bat: c++defs.h is now in build-aux/snippets.
* configure.in: Specify AC_CONFIG_AUX_DIR with build-aux (the
usual parameter).
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
* lib/makefile.w32-in (ARG_NONNULL_H): arg-nonnull.h moved
to build-aux/snippet.
* lib/pthread_sigmask.c, lib/stdlib.in.h, m4/extensions.m4:
* m4/getopt.m4, m4/gnulib-common.m4, m4/pthread_sigmask.m4:
Merge from gnuilib. This fixes porting bugs on Cygwin, Irix, and
Solaris, enables MacOS extensions, and enables nocrash during
'configure'.
* make-dist: Adjust to new build-aux and build-aux/snippit dirs.
* admin/notes/copyright: The files compile, config.guess, config.sub,
depcomp, install-sh, missing, and move-if-change are now in the
new build-aux subdirectory. The files arg-nonnull.h, c++defs.h,
and warn-on-use.h are now in build-aux/snippets. New file
build-aux/snippets/_Noreturn.h.
* leim/Makefile.in (install): install-sh is now in build-aux.
* lib-src/Makefile.in ($(DESTDIR)${archlibdir}): install-sh moved
to build-aux.
* msdos/sedlibmk.inp (CONFIG_CLEAN_VPATH_FILES): Adjust to snippet moves
from top level to build-aux/snippet.
* src/Makefile.in (gl-stamp): move-if-change is now in build-aux.
test, which runs afoul of Automake installations where, for example,
/usr/share/aclocal contains a copy of gl_THREADLIB.
Problem reported by Sven Joachim in
<http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00529.html>.
This is just a quick temporary fix, specific to Emacs; I'll work
with the other gnulib maintainers to get a more-permanent fix.
* Makefile.in (GNULIB_TOOL_FLAGS): Do not avoid sigprocmask.
* configure.in (AC_TYPE_UID_T): New dummy macro.
Configure gnulib after adjusting LIBS,
so that gnulib can assume the libraries in LIBS.
* lib/pthread_sigmask.c, lib/sigprocmask.c, m4/signalblocking.m4:
New files, automatically imported from gnulib.
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
* src/Makefile.in (LIB_PTHREAD_SIGMASK): New macro.
(LIBES): Use it.
* Makefile.in (GNULIB_MODULES): Add pthread_sigmask.
(GNULIB_TOOL_FLAGS): Avoid sigprocmask. Emacs does its own
implementation of 'sigprocmask' on Windows, and it assumes
'sigprocmask' on non-Windows hosts, so it doesn't need the
sigprocmask module.
* lib/signal.in.h, m4/pthread_sigmask.m4, m4/signal_h.m4:
New files, automatically imported from gnulib.
* lib/gnulib.mk, m4/gl-comp.m4: Automatically-imported update
due to the above changes.
* .bzrignore: Add lib/signal.h.
* Makefile.in (GNULIB_MODULES): Add dup2.
* configure.in: Do not check for dup2; gnulib does that now.
* lib/dup2.c, m4/dup2.m4: New files, from gnulib.
* src/sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
* .bzrignore: Add lib/alloca.h.
* Makefile.in (GNULIB_MODULES): Add alloca-opt.
* configure.in (AC_FUNC_ALLOCA): Remove almost all the alloca stuff,
as gnulib now does that for us. Put alloca check after gl_INIT.
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
* lib/alloca.in.h, m4/alloca.m4: New files, from gnulib.
fakemail: Remove dependency on ignore-value.
* Makefile.in (GNULIB_MODULES): Add stdio.
* lib/stdio.in.h, m4/stdio_h.m4: New files, automatically
imported from gnulib.
[lib-src/ChangeLog]
fakemail: Remove dependency on ignore-value.
This undoes some of the recent fakemail-related changes.
It is made possible due to recent changes to gnulib's stdio module.
* Makefile.in (fakemail${EXEEXT}): Do not depend on ignore-value.h.
* fakemail.c: Do not include ignore-value.h.
(put_line): Do not use ignore_value.
Work around some portability problems with symlinks.
* Makefile.in (GNULIB_MODULES): Add lstat, readlink, symlink.
* configure.in (lstat, HAVE_LSTAT): Remove special hack.
* lib/lstat.c, lib/readlink.c, lib/stat.c, lib/symlink.c:
* m4/dos.m4, m4/lstat.m4, m4/readlink.m4, m4/stat.m4, m4/symlink.m4:
New files, automatically generated from gnulib.
* aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk:
* lib/stdlib.in.h, m4/gl-comp.m4, m4/stdlib_h.m4: Regenerate.
2011-02-22 Paul Eggert <eggert@cs.ucla.edu>
[src/ChangeLog]
Work around some portability problems with symlinks.
* fileio.c (Frename_file, Fmake_symbolic_link, Ffile_symlink_p):
Simplify the code by assuming that the readlink and symlink calls
exist, even if they always fail on this host.
(Ffile_readable_p): Likewise, for fifos.
* config.in: Regenerate.
* aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk, m4/gl-comp.m4:
* src/config.in: Regenerate.
* lib/md5.c, lib/md5.h: Regenerate with simpler version, which
assumes C99-style <stdint.h>, supplied by the stdint module.
* lib/stdint.in.h, m4/longlong.m4, m4/stdint.m4: New files,
generated from gnulib.
* src/deps.mk (fns.o): Do not depend on md5.h, fixing a typo in
the earlier patch.
* Makefile.in (MAKEFILE_MODULES): Add crypto/md5.
* admin/notes/copyright: Remove src/md5.c and src/md5.h as
special cases.
* src/Makefile.in (base_obj): Remove md5.o, since this file
is in lib now.
* src/deps.mk (md5.o): Remove.
* aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk, m4/gl-comp.m4:
Regenerate.
* lib/md5.c: Regenerate. This renames the file from src/md5.c,
and adds some porting improvements from gnulib.
* lib/md5.h: Regenerate, likwise; rename from src/md5.h.
* m4/md5.m4: New file, from gnulib.
2011-02-18 Paul Eggert <eggert@cs.ucla.edu>
* configure: Regenerate from the following.
2011-01-30 Paul Eggert <eggert@cs.ucla.edu>
mktime: clarify long_int width checking
* lib/mktime.c (long_int_is_wide_enough): Move this assertion to
the top level, to make it clearer that the assumption about
long_int width is being checked. See
<http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00554.html>.
2011-01-29 Paul Eggert <eggert@cs.ucla.edu>
TYPE_MAXIMUM: avoid theoretically undefined behavior
* lib/intprops.h (TYPE_MINIMUM, TYPE_MAXIMUM): Do not shift a
negative number, which the C Standard says has undefined behavior.
In practice this is not a problem, but might as well do it by the book.
Reported by Rich Felker and Eric Blake; see
<http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00493.html>.
* m4/mktime.m4 (AC_FUNC_MKTIME): Likewise.
* lib/mktime.c (TYPE_MAXIMUM): Redo slightly to match the others.
mktime: #undef mktime before #defining it
* lib/mktime.c (mktime) [DEBUG]: #undef mktime before #defining it.
mktime: systematically normalize tm_isdst comparisons
* lib/mktime.c (isdst_differ): New function.
(__mktime_internal): Use it systematically for all isdst comparisons.
This completes the fix for libc BZ #6723, and removes the need for
normalizing tm_isdst. See
<http://sourceware.org/bugzilla/show_bug.cgi?id=6723>
(not_equal_tm) [DEBUG]: Use isdst_differ here, too.
mktime: fix some integer overflow issues and sidestep the rest
This was prompted by a bug report by Benjamin Lindner for MinGW
<http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00472.html>.
His bug is due to signed integer overflow (0 - INT_MIN), and I
I scanned through mktime.c looking for other integer overflow
problems, fixing all the bugs I found.
Although the C Standard says the resulting code is still not safe
in the presence of integer overflow, in practice it should be good
enough for all real-world two's-complement implementations, except
for debugging environments that deliberately trap on integer
overflow (e.g., gcc -ftrapv).
* lib/mktime.c (WRAPV): New macro.
(SHR): Also check that long_int and time_t shift right in the
usual way, before using the fast-but-unportable method.
(TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove, no longer
used. The code already assumed two's complement, so there's
no need to test for alternatives. All uses removed.
(TYPE_MAXIMUM): Don't rely here on overflow behavior not defined by
the C standard. Problem reported by Rich Felker in
<http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00488.html>.
(twos_complement_arithmetic): Also check long_int and time_t.
(time_t_avg, time_t_add_ok, time_t_int_add_ok): New functions.
(guess_time_tm, ranged_convert, __mktime_internal): Use them.
(__mktime_internal): Avoid integer overflow with unary subtraction
in two instances where -1 - X is an adequate replacement for -X,
since the calculations are approximate.
2011-01-29 Eric Blake <eblake@redhat.com>
mktime: avoid infinite loop
* m4/mktime.m4 (AC_FUNC_MKTIME): Avoid overflow on possibly-signed
type; behavior is still undefined but portable to all known targets.
Reported by Rich Felker.
2011-01-28 Paul Eggert <eggert@cs.ucla.edu>
mktime: avoid problems on NetBSD 5 / i386
* lib/mktime.c (long_int): New type. This works around a problem
on NetBSD 5 / i386, where 'long int' and 'int' are both 32 bits
but time_t is 64 bits, and where I expect the existing code is
wrong in some cases.
(leapyear, ydhms_diff, guess_time_tm, __mktime_internal): Use it.
(ydhms_diff): Bring back the compile-time check for wide-enough
year and yday.
mktime: fix misspelling in comment
* lib/mktime.c (__mktime_internal): Fix misspelling in comment.
This merges all recent glibc changes of importance.
2011-01-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
move-if-change: cope with concurrent mv of identical file.
* move-if-change (CMPPROG): Accept environment
variable as an override for `cmp'.
(usage): Document CMPPROG.
Adjust comparison to drop stdout. Cope with failure of mv if
the target file exists and is identical to the source, for
parallel builds.
Report from H.J. Lu against binutils in PR binutils/12283.
* configure.in: Invoke the new gnulib macro gl_ASSERT_NO_GNULIB_TESTS.
This makes src/config.in a bit smaller, by removing identifiers
like GNULIB_TEST_MKTIME that Emacs does not need.
* m4/getopt.m4, m4/gnulib-common.m4, m4/include_next.m4:
* m4/multiarch.m4, m4/stddef_h.m4, m4/time_h.m4, m4/unistd_h.m4:
Sync from gnulib. This removes a few more unnecessary symbols from
src/config.in, such as AA_APPLE_UNIVERSAL_BUILD and HAVE_STDDEF_H.
* configure, src/config.in: Regenerate.
