* getcwd: don't fail in a deep directory on a system without openatJim Meyering2011-09-191-0/+3
| | | | | | | | | | | | Before this change, getcwd would fail when called from a directory of depth PATH_MAX / 3 or greater. That was due to the fact that the non-openat implementation used "..", "../..", "../../..", etc. to access ancestor directories. With too many, that string would be longer than PATH_MAX. * lib/getcwd.c (HAVE_OPENAT_SUPPORT): Define also when we are using gnulib's openat replacement. * m4/openat.m4: Set GNULIB_OPENAT, so getcwd.c knows when we're using the replacement function.
* openat: test for fstatat (..., 0) bugPaul Eggert2011-09-031-11/+10
| | | | | | | | | | | | | | | | | | | Further testing with tar suggests that fstatat (..., 0) does not work in general, on AIX 7.1; see <http://lists.gnu.org/archive/html/bug-tar/2011-09/msg00023.html>. So, give up entirely on AIX 7.1's fstatat, and fall back on our replacement fstatat (which is what older AIX releases were using anyway). * lib/fstatat.c (fstatat) [HAVE_FSTATAT]: Do not undef. The only use is now changed to orig_fstatat. This was probably the right thing to do anyway. (FSTATAT_AT_FDCWD_0_BROKEN): Remove; no longer used. (rpl_fstatat) [FSTATAT_ZERO_FLAG_BROKEN]: Remove. (rpl_fstatat): Simplify, assuming !FSTATAT_ZERO_FLAG_BROKEN. (AT_FUNC_NAME) [FSTATAT_ZERO_FLAG_BROKEN]: Now rpl_fstatat. * m4/openat.m4 (gl_FUNC_FSTATAT): Test for the more-general bug and define FSTATAT_ZERO_FLAG_BROKEN, not FSTATAT_AT_FDCWD_0_BROKEN, if the bug is found.
* openat: test for fstatat (AT_FDCWD, ..., 0) bugPaul Eggert2011-09-031-3/+32
| | | | | | | | | | | This tests for another fstatat bug on AIX 7.1: fstatat (AT_FDCWD, ..., 0) does not work. See <http://lists.gnu.org/archive/html/bug-tar/2011-09/msg00015.html>. * lib/fstatat.c (FSTATAT_AT_FDCWD_0_BROKEN) (LSTAT_FOLLOWS_SLASHED_SYMLINK): Default to 0. (rpl_fstatat): Adjust so that it works around either (or both) bugs if present. * m4/openat.m4 (gl_FUNC_FSTATAT): Test for this fstatat bug.
* openat: work around AIX 7.1 fstatat issuePaul Eggert2011-09-011-47/+4
| | | | | | | | | | | | This should fix the problem that was not properly fixed in the previous change, dated 2011-08-30. * lib/fstatat.c: Include <sys/stat.h> twice, the first with __need_system_stat_h defined. (orig_fstatat) [HAVE_FSTATAT]: New function. (rpl_fstatat): Go back to the old way of doing things, except call orig_fstatat instead of fstatat. * m4/openat.m4 (gl_FUNC_FSTATAT): Remove unnecessary check for openat. Remove unnecessary check whether fstatat fills in st_size etc.
* openat: work around AIX 7.1 fstatat bugPaul Eggert2011-08-301-5/+62
| | | | | | | | | | | | | | Problem reported by Kevin Brott for GNU tar, in the thread containing <http://lists.gnu.org/archive/html/bug-tar/2011-08/msg00015.html>. * lib/fstatat.c (rpl_fstatat): Do not invoke underlying fstatat if FSTATAT_ST_SIZE_ETC_BROKEN. (fstatat) [FSTATAT_ST_SIZE_ETC_BROKEN && HAVE_FSTATAT]: #define to rpl_fstatat. * m4/openat.m4 (gl_FUNC_FSTATAT): New macro, with the fstatat-relevant part of gl_FUNC_OPENAT. Also, check for the AIX 7.1 bug, and use AC_CHECK_FUNCS_ONCE for fstatat. (gl_FUNC_OPENAT): Use it. Use AC_CHECK_FUNCS_ONCE for fchmodat, mkdirat, openat and unlinkat.
* openat: Respect rules for use of AC_LIBOBJ.Bruno Haible2011-06-161-10/+2
| | | | | | * m4/openat.m4 (gl_FUNC_OPENAT): Call AC_CHECK_FUNCS instead of AC_REPLACE_FUNCS. Move AC_LIBOBJ invocations from here... * modules/openat (configure.ac): ... to here.
* lstat, openat: Respect rules for use of AC_LIBOBJ.Bruno Haible2011-06-161-3/+3
| | | | | | | | | | | * m4/lstat.m4 (gl_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Renamed from AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK. Set variable gl_cv_func_lstat_dereferences_slashed_symlink. Don't invoke AC_LIBOBJ. (gl_PREREQ_LSTAT): New macro, extracted from gl_FUNC_LSTAT. (gl_FUNC_LSTAT): Update. Remove gl_PREREQ_LSTAT code. * modules/lstat (configure.ac): Invoke AC_LIBOBJ and gl_PREREQ_LSTAT here. * m4/openat.m4 (gl_FUNC_OPENAT): Update.

* many *.m4 files: improve m4 quotingJim Meyering2009-01-141-4/+4
| | | | | | | | | | | | | | | | 99% of this change was performed by running the following commands: git ls-files | grep '\.m4$' | xargs perl -pi \ -e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \ -e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \ -e 's/(AC_\w+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g;' \ -e 's/(AC_\w+\((?:\[[^,]+?\], ){3})([^,[()]+?)([,)])/$1\[$2]$3/g' perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4 The remainder were to add Copyright dates, increment serial numbers, undo some changes in comments, exclude m4/intl.m4, and add quotes around the "1" in ",1" where the unusual spacing prohibited the above regexps from doing the job.

| | | | | | | | | * m4/openat.m4 (gl_FUNC_FCHOWNAT_DEREF_BUG): Create the dangling symlink required for the run-test. Without it, this test would always declare that fchownat doesn't work, and client code would unnecessarily use the replacement function with fixed libc. (gl_FUNC_FCHOWNAT): Eliminate a variable that wasn't initialized. Reported by Greg Schafer.
