Paul Eggert b7bc3c1a 2016-04-09T01:28:36 mbrtowc: work around glibc bug#19932 Fix mbrtowc so that it never returns -1 in the C locale, as this conflicts with a future version of POSIX http://austingroupbugs.net/view.php?id=663#c2738 and causes problems with GNU grep: http://bugs.gnu.org/23234 See glibc bug 19932: https://sourceware.org/bugzilla/show_bug.cgi?id=19932 * doc/posix-functions/mbrlen.texi (mbrlen): * doc/posix-functions/mbrtowc.texi (mbrtowc): Document the glibc bug. * lib/mbrtowc.c [C_LOCALE_MAYBE_EILSEQ]: Include hard-locale.h, locale.h.

Bruno Haible 485f1270 2016-01-21T11:32:20 wcwidth: Replace also on OpenBSD 5.8 * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Check the value of wcwidth(0xFF1A). * doc/posix-functions/wcwidth.texi: Update.
KO Myung-Hun 8968c785 2014-11-28T16:43:14 utimes: detect utimes() correctly on OS/2 kLIBC utimes() of OS/2 kLIBC has some limitations. 1. OS/2 itself supports a file date since 1980 year in local time. 2. OS/2 itself supports only even seconds for a file time. 3. utimes() of OS/2 kLIBC does not work on an opened file. * m4/utimes.m4: Detect utimes() correctly on OS/2 kLIBC. * doc/posix-functions/utimes.texi: Document the above limitations of utimes() on OS/2 kLIBC.
Pádraig Brady 95c48427 2016-01-15T16:12:03 doc: mention unfixed issues with unsupported localtime() values Note perl has configure time checks in place to avoid this. * doc/posix-functions/localtime.texi: Mention that FreeBSD 10 returns nonsense for localtime(2^56). * doc/posix-functions/localtime_r.texi: Likewise.
Pádraig Brady 5ac0e2ba 2016-01-14T10:04:58 doc: mention setlocale() issues on OpenBSD * doc/posix-functions/setlocale.texi: Mention setlocale(LC_ALL,"") never fails, and the need to check categories individually.
Paul Eggert 848a19c7 2015-06-06T00:56:01 fsync: document AIX misbehavior * doc/posix-functions/fsync.texi (fsync): Document failure on AIX with read-only file descriptor.
Pádraig Brady 8c9cfa07 2015-05-31T03:08:52 readlinkat: avoid OS X 10.10 trailing slash bug * doc/posix-functions/readlink.texi: Mention that OS X 10.10 has this bug. * doc/posix-functions/readlinkat.texi: Likewise. Also mention that OS X 10.10 has this function. * lib/readlinkat.c (rpl_readlinkat): Handle the trailing slash bug, as done for readlink(). * m4/readlinkat.m4 (gl_FUNC_READLINKAT): Check for the readlink() trailing slash bug, and assume readlinkat() has the same issue. Also fix a typo where $gl_cv_decl_readlink_works was tested, rather than the correct $gl_cv_decl_readlinkat_works.
Pádraig Brady c79f3527 2015-05-29T03:11:59 linkat: avoid OS X 10.10 trailing slash with symlink bug On Darwin 14.3.0 linkat(,"path1",,"dangling_symlink/",) causes the symlink to be dereferenced, and if it points to a non existent file, that file will be created as a hard link to "path1". This fixes a test failure in test-linkat.c. * m4/linkat.m4 (gl_FUNC_LINKAT): Augment the test with this case. The existing workaround in linkat.c for trailing slash issues, suffices for this case. * doc/posix-functions/linkat.texi: Add OS X 10.10 to the list of platforms with trailing slash issues.
Pádraig Brady e176ee0b 2015-05-28T14:15:08 unlinkat: handle ignoring of ".." on Darwin 14 * lib/unlinkat.c: unlinkat() has the same bug as unlink() on Mac OS X 10.10, where it ignores paths with a trailing "..", so handle in the same manner. * m4/unlinkat.m4: Comment on this Darwin issue. * doc/posix-functions/unlink.texi: Update the latest version where the issue was seen. * doc/posix-functions/unlinkat.texi: Mention this issue. Fixes a test failure in test-unlinkat.c.

In some cases this means a larger output buffer is needed.
Pádraig Brady 8b62c05c 2014-11-28T10:57:31 doc: mention that _BSD_SOURCE is deprecated for _DEFAULT_SOURCE * doc/posix-functions/setjmp.texi: Defining _BSD_SOURCE will induce warnings unless _DEFAULT_SOURCE is also defined.
Pádraig Brady c8e57ce5 2014-10-31T18:12:15 linkat: wrap to handle symlinks on OS X 10.10 * m4/linkat.m4 (gl_FUNC_LINKAT): linkat() is available on Yosemite but not usable because it doesn't support creating hardlinks to symlinks. Therefore add a generic test for this capability and fallback to our emulation if linkat() fails with ENOTSUP.

Paul Eggert 93ce02b4 2014-05-31T14:07:57 dup2, fcntl, fcntl-h: port to AIX 7.1 This fixes some porting problems discovered when testing the latest grep snapshot on AIX 7.1. I don't think if fixes any bugs in grep but it could be important for other applications. * doc/posix-functions/dup2.texi: * doc/posix-functions/fcntl.texi: * doc/posix-headers/fcntl.texi: Document AIX bugs. * lib/fcntl.in.h (O_CLOEXEC, O_NOFOLLOW, O_TTY_INIT) [_AIX]: Define to 0 if outside 'int' range. * m4/dup2.m4 (gl_FUNC_DUP2): * m4/fcntl.m4 (gl_FUNC_FCNTL): Check for getdtablesize. If it's available, test a value just outside its range instead of testing 1000000. When cross-compiling, guess that AIX will fail this improved test.

Detect this and use gnulib's expl() in that case. Discussed here: http://marc.info/?t=139159081700002&r=1&w=2 (Message from David Coppa on 2014-02-05 to openbsd-tech mailing list).

Eric Blake fdd1b511 2013-09-26T07:07:07 dup2, dup3: work around another cygwin crasher Cygwin 1.7.25 can crash due to an off-by-one bug on an attempt to duplicate a file into the current RLIMIT_NOFILE soft limit, when that limit is smaller than the hard limit. The intent in the cygwin code was to allow the dup and auto-increase the soft limit, which is itself questionable (and which we work around in the gnulib getdtablesize module); but avoiding the crash is worth doing even if the soft limit semantics are wrong. http://cygwin.com/ml/cygwin/2013-09/msg00397.html http://cygwin.com/ml/cygwin-developers/2013-q3/msg00010.html * m4/dup2.m4 (gl_FUNC_DUP2): Expose the bug. * m4/dup3.m4 (gl_FUNC_DUP3): Likewise. * tests/test-dup2.c (main): Likewise. * lib/dup2.c (rpl_dup2): Use setdtablesize to avoid it. * lib/dup3.c (dup3): Likewise. * doc/posix-functions/dup2.texi (dup2): Document it. * doc/glibc-functions/dup3.texi (dup3): Likewise.
