d9c5af06	2011-08-12T00:33:43	base64: Reference latest RFC. * lib/base64.c: Fix comment to reference RFC 4648. Suggested by Bruno Haible <bruno@clisp.org> and Gijs van Tulder <gvtulder@gmail.com>.
08c11765	2011-08-10T12:36:13	base64: fix off-by-one buffer size bug Problem and (trivial) fix reported by Gijs van Tulder in <http://lists.gnu.org/archive/html/bug-gnulib/2011-08/msg00083.html>. * lib/base64.c (base64_decode_alloc_ctx): Allocate one more byte. * tests/test-base64.c (main): Catch the bug.
5b9e0c3c	2011-08-10T05:28:29	closein: correct comments * lib/closein.c (close_stdin): Improve comments. Signed-off-by: Eric Blake <eblake@redhat.com>
7d7ec765	2011-08-09T15:50:12	fseeko: remove unneeded hack Now that the fixed fseeko doesn't fail, we can remove the hack that was previously making the testsuite pass. * tests/test-fflush2.c (main): Don't special-case SEEK_END. Signed-off-by: Eric Blake <eblake@redhat.com>
a769adbf	2011-08-09T15:18:31	fseeko: fix bug on glibc Commit 1074f45959f had a bug on glibc that caused the unit test to fail, but instead of figuring why the failure was happening, we instead added a partial hack to avoid the problem in the scenario covered by the testsuite. https://lists.gnu.org/archive/html/bug-gnulib/2009-01/msg00171.html But that hack doesn't cover all scenarios, and papers over the real issue: if you fopen()/ftell()/fseek(,0,SEEK_END)/ftell(), then the stream should be positioned at the same place as the underlying fd, even though no I/O occurred, and without requiring an fflush() in the middle. * lib/fseeko.c (fseeko): Set stream offset to match fd offset. Reported by John W. Eaton. Signed-off-by: Eric Blake <eblake@redhat.com>

da4d6974	2011-07-07T11:37:37	fts: introduce FTS_NOATIME This gives clients the option to try a non-invasive traversal, where merely visiting a directory does not update its timestamp, where such is supported by the kernel. Note that this is best-effort. FTS_NOATIME is silently ignored on systems that lack O_NOATIME support - it is up to the caller to decide whether to issue an error when the gnulib replacement <fcntl.h> defined O_NOATIME to 0, and/or detect older Linux kernels where O_NOATIME is defined to non-zero but has no effect. Note that whiteout support and O_NOATIME support are currently orthogonal: there is no way to get O_NOATIME behavior when using __opendir2 to visit whiteouts on BSD systems. So far, I don't know of any system with both __opendir2 and O_NOATIME; if such a system exists, then fts_build() needs a tweak (then again, such a system would probably add DTF_NOATIME for __opendir2). * lib/fts_.h (FTS_NOATIME): New bit flag. (FTS_OPTIONMASK): Adjust. * lib/fts.c (diropen, fts_open, fts_build): Honor it. (fd_ring_check): Debug code unconditionally uses O_NOATIME.

3dbe75e4	2011-06-29T15:46:50	pipe, pipe2: don't corrupt fd on error I noticed a potential subtle double-close bug in libvirt. There, a common idiom is to initialize an int fd[2]={-1,-1}, then have multiple error paths goto common cleanup code. In the cleanup code, the fds are closed if they are not already -1; this works if the error label is reached before the pipe call, or after pipe succeeds, but if it was the pipe call itself that jumped to the error label, then it is relying on failed pipe() not altering the values already in fd array prior to the failure. Our pipe2 replacement violated this assumption, and could leave a non-negative value in the array, which in turn would let libvirt close an already-closed fd, possibly nuking an unrelated fd opened by another thread that happened to get the same value. As a result, I raised a POSIX issue regarding the behavior of pipe on failure: http://austingroupbugs.net/view.php?id=467 Using that test program, I learned that most systems leave fd unchanged on error, but that mingw always assigns -1 into the array. This fixes the mingw pipe() replacement, as well as the gnulib pipe2() replacement. I don't know of any race-free way to work around a cygwin crash: http://cygwin.com/ml/cygwin/2011-06/msg00328.html - we could always open() and then close() two fds to guess whether two spare fd still remain before calling pipe(), but that is racy. * lib/pipe.c (pipe): Leave fd unchanged on error. * lib/pipe2.c (pipe2): Likewise. * doc/posix-functions/pipe.texi (pipe): Document cygwin issue. * doc/glibc-functions/pipe2.texi (pipe2): Likewise.

Admittedly, this behavior is nice, since a truncated integer is misleading, but all other platforms use maximal strings on ERANGE and we are already replacing strerror_r for other reasons, so it is easier to work around this behavior than to adjust the testsuite (how do you quickly decide if the only reason that the ERANGE string was shorter than maximal was because the implementation avoided truncating an integer?). This patch intentionally avoids dragging in the strnlen module. * lib/strerror_r.c (strerror_r): Always use maximal string. * doc/posix-functions/strerror_r.texi (strerror_r): Document it.

Meanwhile, if buf is short enough for ERANGE, then we can't use strstr to look for "Unknown" or "Undefined" in the resulting message, like we had been doing for strerror().

fts: introduce FTS_NOATIME This gives clients the option to try a non-invasive traversal, where merely visiting a directory does not update its timestamp, where such is supported by the kernel. Note that this is best-effort. FTS_NOATIME is silently ignored on systems that lack O_NOATIME support - it is up to the caller to decide whether to issue an error when the gnulib replacement <fcntl.h> defined O_NOATIME to 0, and/or detect older Linux kernels where O_NOATIME is defined to non-zero but has no effect. Note that whiteout support and O_NOATIME support are currently orthogonal: there is no way to get O_NOATIME behavior when using __opendir2 to visit whiteouts on BSD systems. So far, I don't know of any system with both __opendir2 and O_NOATIME; if such a system exists, then fts_build() needs a tweak (then again, such a system would probably add DTF_NOATIME for __opendir2). * lib/fts_.h (FTS_NOATIME): New bit flag.

pipe, pipe2: don't corrupt fd on error I noticed a potential subtle double-close bug in libvirt. There, a common idiom is to initialize an int fd[2]={-1,-1}, then have multiple error paths goto common cleanup code. In the cleanup code, the fds are closed if they are not already -1; this works if the error label is reached before the pipe call, or after pipe succeeds, but if it was the pipe call itself that jumped to the error label, then it is relying on failed pipe() not altering the values already in fd array prior to the failure. Our pipe2 replacement violated this assumption, and could leave a non-negative value in the array, which in turn would let libvirt close an already-closed fd, possibly nuking an unrelated fd opened by another thread that happened to get the same value. As a result, I raised a POSIX issue regarding the behavior of pipe on failure: http://austingroupbugs.net/view.php?id=467 Using that test program, I learned that most systems leave fd unchanged on error, but that mingw always assigns -1 into the array. This fixes the mingw pipe() replacement, as well as the gnulib pipe2() replacement. I don't know of any race-free way to work around a cygwin crash: http://cygwin.com/ml/cygwin/2011-06/msg00328.html - we could always open() and then close() two fds to guess whether two spare fd still remain before calling pipe(), but that is racy. * lib/pipe.c (pipe): Leave fd unchanged on error. * lib/pipe2.c (pipe2): Likewise. * doc/posix-functions/pipe.texi (pipe): Document cygwin issue. * doc/glibc-functions/pipe2.texi (pipe2): Likewise.

strerror_r: fix OpenBSD behavior on out-of-range On OpenBSD, strerror_r(1000,buf,19) gives "Unknown error: " rather than "Unknown error: 100" while failing with ERANGE. Admittedly, this behavior is nice, since a truncated integer is misleading, but all other platforms use maximal strings on ERANGE and we are already replacing strerror_r for other reasons, so it is easier to work around this behavior than to adjust the testsuite (how do you quickly decide if the only reason that the ERANGE string was shorter than maximal was because the implementation avoided truncating an integer?).

strerror_r: fix OpenBSD behavior on 0 OpenBSD treats strerror_r(0,,) as a success, but with a message "Undefined error: 0"; while this is distinct from strerror_r(-1,,) returning "Unknown error: -1", it does not imply success. Meanwhile, if buf is short enough for ERANGE, then we can't use strstr to look for "Unknown" or "Undefined" in the resulting message, like we had been doing for strerror().

alloca: port to compilers that can optimize like GCC 4.6.0 * lib/alloca.c (find_stack_direction): New signature, taken from Autoconf git. This works with GCC 4.6.0. This code should never be used with GCC 4.6.0 itself, as GCC has alloca, but it might be used with other compilers that optimize as well as GCC 4.6.0 does. (alloca): Adjust to new signature. * m4/alloca.m4 (__AC_LIBOBJ_ALLOCA) [Autoconf version < 2.69]: New macro, which patches Autoconf in a similar way.

c-stack: stop worrying about stack direction * lib/c-stack.c (find_stack_direction): Remove. (segv_handler): Don't worry about stack direction growth, as it's too much of a pain to configure this correctly, given how compilers are optimizing-away our stack-growth detection code. Instead, assume that any access to just before or just after the stack is OK. * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC): Don't require AC_FUNC_ALLOCA; no longer needed.
