* futimens, utimensat: work around ntfs-3g bugEric Blake2009-12-302-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | With ntfs-3g, use of a single UTIME_OMIT failed to make any change to the remaining two timestamps. Furthermore, the previous fix for ctime happens to be specific to xfs, rather than global to the kernel. Therefore, to be valid, a cache would have to be per-device, which gets too expensive, especially considering that the cost of a preparatory stat pulls the file into kernel cache to speed up the resulting utimensat. So, blindly massage UTIME_OMIT on Linux, even on working filesystems like ext4. The bugs in xfs and ntfs-3g were reported to the kernel folks, and fixes written, but it will be several years before gnulib can assume that file systems in use have picked up the fixes. * lib/utimensat.c (rpl_utimensat): Drop attempts to cache whether a ctime bug is present, and expand workaround to cover ntfs-3g. * lib/utimens.c (fdutimens, lutimens): Likewise.

* getopt-gnu: flush out another BSD bugEric Blake2009-11-271-17/+43
| | | | | | | | | | | | | | | | | | | | | | | | | POSIX requires 'echo foo > bar; m4 -Dfoo=1 bar -Dfoo=2 bar' to output '1' then '2'. To achieve this, m4 relies on the GNU getopt{,_long} extension of a leading '-'. However, BSD getopt fails to honor this extension when POSIXLY_CORRECT. Also, BSD getopt fails to reparse POSIXLY_CORRECT from the environment even when a reset is requested (whether by optreset=1 or by optind=0). * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Test for the bug. * tests/test-getopt.c (main): Check POSIXLY_CORRECT first, to flush out BSD bug. * tests/test-getopt.h (test_getopt): End lists with NULL. * tests/test-getopt_long.h (test_getopt_long): Likewise.
