* m4/getloadavg.m4 (gl_FUNC_GETDELIM): Set HAVE_GETLOADAVG. Move
AC_LIBOBJ and gl_PREREQ_GETLOADAVG invocations from here...
* modules/getloadavg (configure.ac): ... to here.
* m4/getloadavg.m4 (gl_GETLOADAVG): Drop argument. Remove test whether
getloadavg.c is in place.
* modules/getloadavg (configure.ac): Drop argument of gl_GETLOADAVG.
Reported by Sam Steingold <sds@gnu.org>.
* modules/getloadavg (Link): New section.
* modules/getloadavg-tests (Makefile.am): Use GETLOADAVG_LIBS for
linking test-getloadavg.
* doc/glibc-functions/getloadavg.texi: Mention that Solaris 2.6 lacks
getloadavg.
See the thread rooted at
<http://lists.gnu.org/archive/html/bug-gnulib/2011-02/msg00090.html>.
* lib/getloadavg.c: Do not include c-strtod.h, cloexec.h, or fcntl--.h.
Include <fcntl.h> only if (defined __linux__ || defined __CYGWIN__
|| defined SUNOS_5 || (defined LOAD_AVE_TYPE && ! defined
__VMS)); previously it was always included (via fcntl--.h).
(getloadavg): Do not use c_strtod. Instead, approximate it by
hand; this is good enough for load averages. Also, do not use
set_cloexec_flag; instead, use the O_CLOEXEC and F_DUPFD_CLOEXEC
flags directly if available and don't bother otherwise. (Packages
that need the extra reliability should use the modules that define
these flags on older platforms that lack them.)
* modules/getloadavg (Depends-on): Remove c-strtod, cloexec,
fcntl-safer.
(configure.ac): AC_FUNC_GETLOADAVG -> gl_GETLOADAVG, as
the former is now obsolescent.
* lib/getloadavg.c [defined gl_GETLOADAVG]: Don't include config.h
or stdbool.h, because they might not exist while configuring.
* m4/fnmatch.m4: Add comment that Autoconf AC_FUNC_FNMATCH is
obsolescent, and programs should use gnulib instead.
* m4/getloadavg.m4: New file, with contents taken from Autoconf
but with prefixes changed.
* .cppi-disable: Add regcomp.c, regex_internal.c, regex_internal.h,
stat-time.h.
* argmatch.h: Include verify.h
(ARGMATCH_VERIFY): Use verify rather than rolling our own.
(ARGMATCH_ASSERT): Remove; unused.
* canonicalize.c: Assume STDC_HEADERS.
* exclude.c: Include "strcase.h".
* regex_internal.h [!defined _LIBC]: Likewise.
* getusershell.c: Include stdio--.h rather than stdio.h
and stdio-safer.h.
(getusershell): Call fopen, not fopen_safer.
* save-cwd.c: Include fcntl--.h rather than fcntl.h.
Do not include unistd-safer.h.
(save_cwd): Don't call fd_safer; no longer needed
now that we include fcntl--.h.
* modules/argmatch (Depends-on): Add verify.
* modules/getloadavg (Depends-on): Depend on fcntl-safer, not
unistd-safer.
* modules/save-cwd (Depends-on): Likewise.
* backupfile.m4, calloc.m4, chown.m4, cloexec.m4, dup2.m4:
* fileblocks.m4, free.m4, ftruncate.m4, getcwd.m4, getpagesize.m4:
* getugroups.m4, group-member.m4, idcache.m4, link-follow.m4:
* mkstemp.m4, mktime.m4, mountlist.m4, nanosleep.m4, pathmax.m4:
* physmem.m4, posixver.m4, putenv.m4, safe-read.m4, same.m4:
* save-cwd.m4, stdio-safer.m4, unistd-safer.m4, unlinkdir.m4:
* userspec.m4, xgetcwd.m4, xreadlink.m4:
Don't bother checking for string.h, stdlib.h, unistd.h.
* fts.m4 (gl_FUNC_FTS_CORE): Don't require
AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK; that's now the lstat
module's job.
* jm-macros.m4 (gl_MACROS): Likewise.
* prereq.m4 (gl_PREREQ): Add gl_FUNC_LSTAT.
* backupfile.c: Use ARGMATCH_VERIFY, just in case.
* posixtm.c (posixtime) [lint]: Initialize *all* of tm0, not just
the .tm_year member, since otherwise gcc-4.0 would now warn about
tm_zone, tm_gmtoff, tm_isdst, tm_yday, tm_wday.
* quotearg.c (quotearg_n_options): Change code to be suboptimal, in
order to avoid an unsuppressible warning from gcc on 64-bit systems.
* lstat.m4 (gl_FUNC_LSTAT):
Use AC_LIBSOURCES to require lstat.c and lstat.h.
Remove obsolete comment.
* xreadlink.m4: Use AC_LIBSOURCES and AC_LIBOBJ.
* xstrtod.m4: Likewise.
glibc-related files.
* lib/intprops.h: New file.
* lib/getloadavg.c: Include it instead of limits.h.
(INT_STRLEN_BOUND): Remove.
* lib/human.c: Include intprops.h.
(group_number): Use INT_STRLEN_BOUND instead of rolling it ourself.
* lib/human.h (LONGEST_HUMAN_READABLE): Use 146/485 rather than 302/1000.
* lib/inttostr.h: Include intprops.h instead of limits.h.
(INT_STRLEN_BOUND, INT_BUFSIZE_BOUND): Remove.
* lib/mktime.c (TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT): New macros,
for consistency with intprops.h.
(time_t_is_integer, twos_complement_arithmetic): Use them.
* lib/sig2str.h: Include <signal.h>, intprops.h.
(INT_STRLEN_BOUND): Remove.
* lib/strftime.c (TYPE_SIGNED): Remove.
(INT_STRLEN_BOUND): Switch to same implementation as intprops.h.
* lib/strtol.c: Adjust comments to match intprops.h.
* lib/userspec.c: Include intprops.h.
(TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Remove.
* lib/utimecmp.c, lib/xnanosleep.c, lib/xstrtol.c: Likewise.
* lib/utimecmp.c (utimecmp): Use TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT
instead of rolling our own expressions.
* lib/xstrtol.c: Include xstrtol.h first, to test interface.
* modules/getloadavg (Files): Add lib/intprops.h.
* modules/human (Files): Likewise.
* modules/inttostr (Files): Likewise.
* modules/sig2str (Files): Likewise.
