* Fix 'array subscript is above array bounds' warning in res_send.cSiddhesh Poyarekar2014-12-162-1/+6
| | | | | | | | | | I see this warning in my build on F21 x86_64, which seems to be due to a weak check for array bounds. Fixed by making the bounds check stronger. This is not an actual bug since nscount is never set to anything greater than MAXNS. The compiler however does not know this, so we need the stronger bounds check to quieten the compiler.
* Modify libio/tst-fopenloc.c to use test-skeleton.cArjun Shankar2014-12-162-2/+7
| | | | | | This test would earlier fail when run under test-skeleton.c due to bug #17522 in 'fputws'. That bug is now fixed and so this test may be modified.
* Modify stdlib/tst-bsearch.c to use test-skeleton.cArjun Shankar2014-12-162-12/+19
| | | | | | This test used to define a 'struct entry' that conflicts with the definition in search.h included in test-skeleton. The struct is now renamed 'item'.
* Modify stdio-common/tst-fseek.c to use test-skeleton.cArjun Shankar2014-12-162-2/+10
| | | | | This test needs a TIMEOUT longer than the default 2 seconds since it sleeps twice for a second each.

* Move semaphore.h to sysdeps/pthread/.Joseph Myers2014-12-113-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Carlos reported failures in conform/ tests in environments where the compiler used could only find headers in glibc's source and build trees, not any previously installed headers <https://sourceware.org/ml/libc-alpha/2014-09/msg00040.html>. This patch moves nptl/semaphore.h to sysdeps/pthread/semaphore.h so that it can be found by builds from all glibc subdirectories; it's not in any way NPTL-specific. (I left the Makefile setting to install this header in nptl/, but maybe it should move as well - it's just not clear to me what ifeq ($(subdir),...) conditional should be used to select the directory to associate the header with for installation purposes. The path in the toplevel Makefile used for begin-end-check also remains hardcoded; it's a known todo issue to rework that test to run in each subdirectory checking the headers installed from that subdirectory, rather than a separate hardcoded list.) Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). I did *not* test a configuration such as that in which Carlos saw failure. * nptl/semaphore.h: Move to ... * sysdeps/pthread/semaphore.h: ... here. * Makefile (installed-headers): Change nptl/semaphore.h to sysdeps/pthread/semaphore.h.

* Add more headers to include/ for conform tests.Joseph Myers2014-12-113-0/+5
| | | | | | | | | | | | | | | | | | | | | | | Carlos reported failures in conform/ tests in environments where the compiler used could only find headers in glibc's source and build trees, not any previously installed headers <https://sourceware.org/ml/libc-alpha/2014-09/msg00040.html>. This patch adds wrappers for two of the affected headers to include/, which is the normal way to make headers visible when building or testing in directories other than the one containing the header (I suppose these headers weren't needed in any such directories except conform/, or other build or test failures would have resulted). I believe the same issue applies at least to regexp.h and re_comp.h - we don't currently have conform/ expectations for those, but when such expectations are added we'll also need to add header wrappers. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). I did *not* test a configuration such as that in which Carlos saw failure. * include/cpio.h: New file. * include/fmtmsg.h: Likewise.

* intl: Merge with gettext version 0.19.3Will Newton2014-12-1126-1129/+1442
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch merges the latest release of gettext into the intl subdirectory. The initial motivation was to include the plural.y changes which enable building with bison 3.0, but the majority of the other changes are merely cosmetic so it seemed like merging the whole directory was simpler than trying to take it piecemeal. The merge was done by copying across the latext gettext code and adding in a few small glibc changes that have been added over the years that seemed beneficial, as well as a couple of small build fixes that should be merged back to gettext. I also reverted the gettext commit: commit 279b57fc367251666f00e8e2b599b83703451afb Author: Bruno Haible <bruno@clisp.org> Date: Fri Jun 14 12:03:49 2002 +0000 Make absolute pathnames inside $LANGUAGE work. As it caused localedata/tst-setlocale3 to fail and it wasn't clear that glibc wanted that behaviour. The merge has dropped many uses of __glibc_likely/unlikely. This is intentional given that it eases merging. It seems to me that the cost of continually rewriting these lines when merging and the risk of adding bugs when doing so outweighs the benefits of using these macros when code is shared with another project. Tested with make check on x86_64. ChangeLog: 2014-12-11 Will Newton <will.newton@linaro.org> Merge gettext 0.19.3 into intl/.

* Fix MIPS waitid build.Joseph Myers2014-12-102-0/+9
| | | | | | | | | | | | | | | As previously discussed in <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, MIPS (o32) waitid has build warnings (now errors) because a function is declared inline but functions with five-argument syscalls cannot be inlined for MIPS o32. This patch disables the -Winline warnings for waitid.c using a MIPS-specific wrapper file. As it's whole-file disabling, there's no point in using push and pop, so just DIAG_IGNORE_NEEDS_COMMENT is used. * sysdeps/unix/sysv/linux/mips/mips32/waitid.c: New file.
* Fix MIPS sigaction build.Joseph Myers2014-12-102-0/+18
| | | | | | | | | | | | Building MIPS sigaction (for ABIs other than o32) fails because of "'restore_rt' used but never defined", arising from static functions being defined in asms and referred to from C code. There is no corresponding -W option for that warning, so this patch uses -Wno-error for building sigaction.c. * sysdeps/unix/sysv/linux/mips/mips64/Makefile [$(subdir) == signal] (CFLAGS-sigaction.c): New variable. [$(subdir) == nptl] (CFLAGS-sigaction.c): Likewise.

* Fix strftime wcschr namespace (bug 17634).Joseph Myers2014-12-1014-23/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of strftime, a C90 function, ends up bringing in wcschr, which is not a C90 function. Although not a conformance bug (C90 reserves wcs*), this is still contrary to glibc practice of avoiding relying on those reservations; this patch arranges for the internal uses to use __wcschr instead, with wcschr being a weak alias. This is more complicated than some such patches because of the various IFUNC definitions of wcschr (which include code redefining libc_hidden_def in a way that involves creating __GI_wcschr manually and so also needs to create __GI___wcschr after the change of internal uses to use __wcschr). Tested for x86_64 and 32-bit x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). 2014-12-10 Joseph Myers <joseph@codesourcery.com> Adhemerval Zanella <azanella@linux.vnet.ibm.com> [BZ #17634] * wcsmbs/wcschr.c [!WCSCHR] (wcschr): Define as __wcschr.

* Fix tst-ftell-active-handler.c warning.Joseph Myers2014-12-102-1/+6
| | | | | | | | | | | | A recent change to libio/tst-ftell-active-handler.c (postdating my last check for warnings on x86) introduced a format warning from a long int variable used with a %zu format. This patch fixes it by using %ld for the format to match the variable. Tested for x86. * libio/tst-ftell-active-handler.c (do_ftruncate_test): Use %ld format for long int variable.
* manual: Remove incorrect claim that qsort() can be stabilizedAnders Kaseorg2014-12-103-11/+16
| | | | | | | | | | | | Under certain conditions on the size of the array and its items, qsort() may fall back to an in-place quicksort if it cannot allocate memory for a temporary array with malloc(). This algorithm is not a stable sort even if the comparison function is written in the described manner. Fixes #10672. Signed-off-by: Anders Kaseorg <andersk@mit.edu>
