* MODULES.html.sh (Support for systems lacking POSIX:2001): New
module sys_time.
* lib/gethrxtime.c: Include <sys/time.h>, since we can no longer
assume timespec.h defines struct timeval.
* lib/settime.c: Likewise.
* lib/utimens.c: Likewise.
* lib/gettime.c (gettime): Remove test against HAVE_GETTIMEOFDAY,
since we now assume the gettimeofday module.
* lib/tempname.c (__gen_tempname): Likewise.
* lib/gettimeofday.h: Remove.
* lib/gettimeofday.c: Include <sys/time.h> instead of "gettimeofday.h".
Don't include <sys/types.h> and <stdlib.h>; shouldn't be needed.
Include <time.h>, for 'time()'.
(localtime_buffer_addr): Also use this workaround if
TZSET_CLOBBERS_LOCALTIME. Set to a dummy static variable by default,
to simplify the uses. All uses changed.
(localtime, gmtime, tzset, gettimeofday): Reformat slightly so
that #undef is inside {}, and 'const' follows type name consistently.
(tzset): Define replacement only if TZSET_CLOBBERS_LOCALTIME.
(gettimeofday): Do not use the maximum possible value for
tv->tv_usec, since that might break usages other than ls.c.
Instead, we'll leave ls.c alone. This undoes today's patch
by Bruno. Add a compile-time warning for 1s-clock resolution;
we've never observed the problem but might as well keep the
canary.
* lib/nanosleep.c: Include timespec.h first, for interface check.
* lib/nanosleep.c: Include <sys/time.h> unconditionally, since we
now assume the sys_time module.
* lib/tempname.c: Likewise.
* lib/timespec.h: Likewise.
* lib/nanosleep.c: Don't worry about TIME_WITH_SYS_TIME; no longer
needed.
* lib/strftime.c: Likewise.
* lib/timespec.h: Likewise.
* lib/posixtm.c: Include posixtm.h first, for interface check.
Don't worry about TM_IN_SYS_TIME; that's wayyy obsolete.
* lib/posixtm.h: Include stdbool.h and time.h, for proper interface.
* lib/strftime.c: Don't include <sys/types.h>; shouldn't be needed.
* lib/sys_time_.h: New file.
* lib/timespec.h (struct timespec): Use long int, not long.
* m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY):
(gl_FUNC_GETTIMEOFDAY_CLOBBER, gl_PREREQ_GETTIMEOFDAY):
Remove obsolescent call to AC_HEADER_TIME.
* m4/mktime.m4 (AC_FUNC_MKTIME): Likewise.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise.
* m4/strftime.m4 (gl_FUNC_STRFTIME): Likewise.
* m4/timespec.m4 (gl_TIMESPEC, gl_CHECK_TYPE_STRUCT_TIMESPEC):
Likewise.
* m4/tzset.m4 (gl_FUNC_TZSET_CLOBBER): Likewise.
* m4/utimbuf.m4 (gl_CHECK_TYPE_STRUCT_UTIMBUF): Likewise.
* m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY): Move sys/time.h tests
into the sys_time module. Check for gettimeofday just once.
Prefix our variables with gl_, not with ac_ or jm_. Tighten test
for gettimeofday signature to just check the signature. Merely
compile it, since linking doesn't test signature. Improve test for
whether gettimeofday.o is actually needed.
(gl_FUNC_GETTIMEOFDAY_CLOBBER): Renamed from
AC_FUNC_GETTIMEOFDAY_CLOBBER. All uses changed. Use
AC_RUN_IFELSE rather than AC_TRY_RUN. If clobbering, set
and define GETTIMEOFDAY_CLOBBERS_LOCALTIME.
(gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Don't define
GETTIMEOFDAY_CLOBBERS_LOCALTIME; that's gl_FUNC_GETTIMEOFDAY_CLOBBER's
job. Don't define tzset; that's gl_FUNC_TZSET_CLOBBER's job.
* m4/mktime.m4 (AC_FUNC_MKTIME): Just include <time.h> rather
than worrying about sys/time.h.
* m4/nanosleep.m4 (gl_FUNC_NANOSLEEP):
Don't bother worrying about TIME_WITH_SYS_TIME.
* m4/stat-time.m4 (gl_STAT_TIME): Likewise.
* m4/posixtm.m4 (gl_POSIXTM): Remove obsolescent call to AC_STRUCT_TM.
* m4/sys_time_h.m4: New file.
* m4/tzset.m4 (gl_FUNC_TZSET_CLOBBER): Require gl_HEADER_SYS_TIME_H.
Don't include sys/time.h. Return from main rather than exiting.
Define TZSET_CLOBBERS_LOCALTIME, for consistency with other names;
all uses changed.
* modules/gethrxtime (Depends-on): Add sys_time.
* modules/gettime (Depends-on): Likewise.
* modules/gettimeofday (Depends-on): Likewise.
* modules/nanosleep (Depends-on): Likewise.
* modules/settime (Depends-on): Likewise.
* modules/tempname (Depends-on): Likewise.
* modules/utimens (Depends-on): Likewise.
* modules/gettimeofday (Files): Remove lib/gettimeofday.h.
(Include:) Change back to <sys/time.h>.
(Maintainer:) Add self.
* modules/sys_time: New file.
* modules/tempname (Depends-on): Add gettimeofday.
* tests/test-gettimeofday.c: Include <sys/time.h>
rather than gettimeofday.h.

Sync from coreutils.
* doc/getdate.texi (General date syntax): Invalid dates are rejected.
(Time of day items): Mention the possibility of leap seconds.
Problem reported by Dr. David Alan Gilbert.
* lib/chdir-long.c (cdb_free): Don't bother trying to open directory
for write access: POSIX says that must fail.
* lib/fts.c (diropen): Likewise.
* lib/save-cwd.c (save_cwd): Likewise.
* lib/chdir-long.c (cdb_free): Open with O_NOCTTY | O_NONBLOCK as
well, for minor improvements on hosts that lack O_DIRECTORY.
* lib/gettime.c (gettime) [!defined OK_TO_USE_1S_CLOCK]:
Report an error at compile-time if only a 1-second nominal clock
resolution is found.
* lib/lchmod.h: New file.
* lib/mkdir-p.c: Include lchmod.h, lchown.h.
(make_dir_parents): Use lchown rather than chown, and
lchmod rather than chmod.
* lib/mountlist.c (ME_DUMMY): "none" and "proc" file systems are dummies
too. Problem with "none" reported by Bob Proulx. Problem with
"proc" reported by n0dalus.
* lib/mountlist.c: Include <limits.h>.
(dev_from_mount_options)
[defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]:
New function. It no longer assumes "dev=" has the System V meaning
on Linux (since it doesn't). It also parses "dev=" more carefully.
(read_file_system_list)
[defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: Use it.
MOUNTED_GETMNTENT2 is new here; the code didn't used to look for
dev= in that case.
* lib/posixtm.h (PDS_PRE_2000): New macro.
* lib/posixtm.c (year): Arg is now syntax_bits rather than allow_century.
All usages changed. Reject dates outside the range 1969-1999 if
PDS_PRE_2000 is used.
* modules/mkdir-p (Files): Add chdir-safer.c, chdir-safer.h, lchmod.h,
chdir-safer.m4, lchmod.m4.
* modules/openat: Add mkdirat.c, openat-priv.h.
* modules/lib-ignore: New file.
* lib/version-etc.c (COPYRIGHT_YEAR): Update to 2006.
Rewrite fts.c not to change the current working directory,
by using openat, fstatat, fdopendir, etc..
* lib/fts.c [! _LIBC]: Include "openat.h", "unistd--.h", and "fcntl--.h".
[_LIBC] (fchdir): Don't undef or define; no longer used.
(FCHDIR): Define in terms of cwd_advance_fd rather than fchdir.
Now, this `function' always succeeds, and consumes its file descriptor
parameter -- so callers must not close such FDs. Update callers.
(diropen_fd, opendirat, cwd_advance_fd): New functions.
(diropen): Add parameter, SP. Adjust all callers.
Implement using diropen_fd, rather than open.
(fts_open): Initialize new member, fts_cwd_fd.
Remove fts_rft-setting code.
(fts_close): Close fts_cwd_fd, if necessary.
(__opendir2): Define in terms of opendir or opendirat,
depending on whether the FST_NOCHDIR flag is set.
(fts_build): Since fts_safe_changedir consumes its FD, and since
this code must do `closedir(dirp)', dup the dirfd(dirp) argument,
and close the dup'd file descriptor upon failure.
(fts_stat): Use fstatat(...AT_SYMLINK_NOFOLLOW) in place of lstat.
(fts_safe_changedir): Tweak semantics to reflect that this function
now calls cwd_advance_fd and hence consumes its FD argument.
* lib/fts_.h [struct FTS] (fts_cwd_fd): New member.
(fts_rft): Remove now-unused member.
* lib/openat.c (fchownat): New function.
* lib/openat.h (fchmodat, fchownat): Declare.
(chmodat, lchmodat): Define convenience functions.
(chownat, lchownat): Likewise.
* lib/chdir-safer.h, chdir-safer.c: New files.
* lib/modechange.c (mode_compile): Reject an invalid mode string
that starts with an octal digit. From Andreas Gruenbacher.
* lib/openat.c: Include "fcntl--.h" and "unistd--.h", to map open
and dup to open_safer and dup_safer, respectively.
(openat_permissive): Fix typo in comment.
* lib/openat.c: Don't include <stdlib.h>, <unistd.h>, <fcntl.h>,
"gettext.h"; either no longer needed or are guaranteed by openat.h.
(_): Remove; no longer needed.
(openat): Renamed from rpl_openat; no need for rpl_openat
since openat.h renames openat for us.
Replace most of the body with a call to openat_permissive,
to avoid duplicate code.
Port to (probably hypothetical) environments were mode_t is
wider than int.
(openat_permissive): Require mode arg, so that we can check
types better. Put it just after flags. Change cwd failure
indicator from pointer-to-bool to pointer-to-errno-value.
All callers changed.
Invoke openat_save_fail and/or openat_restore_fail if
cwd_errno is null, so that openat can call us.
(openat_permissive, fdopendir, fstatat, unlinkat):
Simplify errno handling to avoid some duplicate code,
as it's OK to set errno on success.
* lib/openat.h: Revamp code so that function macros depend on
__OPENAT_PREFIX only, not also on AT_FDCWD.
(openat_ro): Remove. Caller changed to use openat_permissive.
(openat_permissive): Now a macro, if not a function.
(openat_restore_fail, openat_save_fail): Now always functions,
since mkdirat needs them even if __OPENAT_PREFIX is defined.
* lib/openat-priv.h: New file, defining macros used by mkdirat.c
and openat.c.
* lib/mkdirat.c: Include openat-priv.h.
Remove definitions of macros defined therein.
* lib/openat.c: Likewise.
* lib/mkdirat.c (mkdirat): New file and function.
* lib/openat.h (mkdirat): Declare.
* lib/openat.c (fdopendir): Don't change errno when returning non-NULL.
* lib/openat.h (openat_permissive): Declare.
(openat_ro): Define.
* lib/openat.c (EXPECTED_ERRNO): New macro.
(openat_permissive): New function -- used in remove.c rewrite.
(all functions): Set errno just before returning, only if there
was an actual failure.
Use EXPECTED_ERRNO rather than comparing against only ENOTDIR.
Emulate openat-family functions using Linux's procfs, if possible.
Idea and some code based on Ulrich Drepper's glibc changes.
* lib/openat.c: (BUILD_PROC_NAME): New macro.
Include <stdio.h>, <string.h>, "alloca.h" and "intprops.h".
(rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s,
before falling back on save_cwd and restore_cwd.
(fdopendir, fstatat, unlinkat): Likewise.
* lib/openat.c (fstatat, unlinkat): Perform the syscall directly,
skipping the save_cwd...restore_cwd overhead, if FILE is absolute.
* lib/openat.c (rpl_openat): Use the promoted type (int), not mode_t,
as second argument to va_arg. Otherwise, some versions of gcc
warn that `if this code is reached, the program will abort'.
Add POSIX ACL support
* lib/acl.h (copy_acl, set_acl): Add declarations.
* lib/acl.c (acl_entries): Add fallback implementation for POSIX ACL
systems other than Linux.
(chmod_or_fchmod): New function: use fchmod when possible,
and chmod otherwise.
(file_has_acl): Add a POSIX ACL implementation, with a
Linux-specific subcase.
(copy_acl): Add: copy an acl and S_ISUID, S_ISGID, and
S_ISVTX from one file to another. Fall back to fchmod/chmod when
acls are unsupported.
(set_acl): Add: set a file's acl and S_ISUID, S_ISGID, and
S_ISVTX to a defined value. Fall back to fchmod/chmod when acls
are unsupported.
* m4/lib-ignore.m4: New file.
* m4/lchmod.m4: New file.
* m4/chdir-safer.m4: New file.
* m4/openat.m4 (gl_FUNC_OPENAT): Require and compile mkdirat.c.
Require openat-priv.h.
* m4/acl.m4 (AC_FUNC_ACL): Add POSIX ACL and Linux-specific acl tests.
