2014-12-11Move semaphore.h to sysdeps/pthread/.Joseph Myers3-1/+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.

2014-12-11Add more headers to include/ for conform tests.Joseph Myers3-0/+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.

2014-12-11intl: Merge with gettext version 0.19.3Will Newton26-1129/+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/.

2014-12-10Fix MIPS waitid build.Joseph Myers2-0/+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.
2014-12-10Fix MIPS sigaction build.Joseph Myers2-0/+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.

2014-12-10Fix strftime wcschr namespace (bug 17634).Joseph Myers14-23/+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.

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.

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>

2014-12-10Use -Werror by default, add --disable-werror.Joseph Myers9-14/+79
As discussed starting at <https://sourceware.org/ml/libc-alpha/2014-11/msg00323.html>, this patch makes the glibc build use -Werror by default to avoid accidentally adding new warnings to the build. The configure option --disable-werror can be used to disable this. -Wno-error=undef is temporarily used because the build isn't clean regarding -Wundef warnings. The idea is that once the remaining -Wundef warnings have been cleaned up (in at least one configuration), -Wno-error=undef will be removed. I get a clean build and test on x86_64 (GCC 4.9 branch) with this patch. The expectation is that this may well break the build for some other configurations, and people seeing such breakage should make appropriate fixes to fix or suppress the warnings for their configurations. In some cases that may involve using pragmas as the right fix (I think that will be right for the -Wno-inline issue for MIPS I referred to in <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, for example), in some cases -Wno-error in sysdeps makefiles (__restore_rt in MIPS sigaction, for example), in some cases substantive fixes for the warnings. Note that if, with a view to listing all the warnings then fixing them all, you just look for "warning:" in output from building and testing with --disable-werror, you'll see lots of warnings from the linker about functions such as tmpnam. Those warnings can be ignored - only compiler warnings are relevant to -Werror, not linker warnings. * configure.ac (--disable-werror): New configure option. (enable_werror): New AC_SUBST. * configure: Regenerated. * config.make.in (enable-werror): New variable. * Makeconfig [$(enable-werror) = yes] (+gccwarn): Add -Werror -Wno-error=undef. (+gccwarn-c): Do not use -Werror=implicit-function-declaration. * manual/install.texi (Configuring and compiling): Document --disable-werror. * INSTALL: Regenerated. * debug/Makefile (CFLAGS-tst-chk1.c): Add -Wno-error.

2014-12-10Disable -Wdeprecated-declarations for register_printf_function calls in ↵Joseph Myers2-0/+11
tst-printfsz.c. This patch uses diagnostic control pragmas to disable warnings in stdio-common/tst-printfsz.c for use of the deprecated register_printf_function. Because this test is testing printf_size and printf_size_info, and the latter has the interface expected for register_printf_function instead of the newer register_printf_specifier, it seems correct for this test to use the deprecated interface (wrapping printf_size_info in some way to use register_printf_specifier would seem an excessive change to what's tested). Tested for x86_64. * stdio-common/tst-printfsz.c: Include <libc-internal.h>. (main): Disable -Wdeprecated-declarations around calls to register_printf_function.
2014-12-10Disable -Wdiv-by-zero for some tests in stdio-common/tst-unlockedio.c.Joseph Myers2-0/+17
This patch uses diagnostic control pragmas to disable some division-by-zero warnings in stdio-common/tst-unlockedio.c. This is another test where disabling warnings using diagnostic pragmas seems appropriate (the warnings are not wildly inappropriate for what the test deliberately does; the deliberate use of unusual arguments to the macros being tested means that changing the arguments in a way that avoids the warning would also unduly perturb what is being tested). Tested for x86_64. * stdio-common/tst-unlockedio.c: Include <libc-internal.h>. (do_test): Disable -Wdiv-by-zero around some calls to fwrite_unlocked and fread_unlocked.
2014-12-10Add macros for diagnostic control, use for scanf %a tests.Joseph Myers4-0/+73
In <https://sourceware.org/ml/libc-alpha/2014-11/msg00326.html>, Roland requested internal macros for use of "#pragma GCC diagnostic". This patch adds such macros and uses them to disable -Wformat warnings for some code testing GNU scanf %as where GCC expects C99 scanf %a (several other stdio tests currently use -Wno-format to disable warnings). Limitations in GCC's diagnostic pragmas require separate macros before and after the code generating the warnings, rather than a single macro taking that code as an argument. The macros are named DIAG_*_NEEDS_COMMENT to emphasise to reviewers the need for a comment accompanying any use of them (such comments may however just appear once for several uses of the macros for the same issue in the same file). I put a GCC version in the arguments to DIAG_IGNORE_NEEDS_COMMENT, as that seems something useful to grep for when obsoleting support for an old GCC version and needing to decide if warning-disabling code is still relevant. These macros should be usable for replacing existing -Wno-* use in makefiles (as also suggested by Roland), though I have no plans to work on that (only on use of the macros in cases where warnings are currently present that need disabling to use -Werror). Tested for x86_64. * include/libc-internal.h (DIAG_PUSH_NEEDS_COMMENT): New macro. (DIAG_POP_NEEDS_COMMENT): Likewise. (_DIAG_STR1): Likewise. (_DIAG_STR): Likewise. (DIAG_IGNORE_NEEDS_COMMENT): Likewise. * stdio-common/bug21.c: Include <libc-internal.h>. (do_test): Disable -Wformat around call to sscanf. * stdio-common/scanf14.c: Include <libc-internal.h>.

2014-12-06Fix pthreads getrlimit, gettimeofday namespace (bug 17682).Joseph Myers12-9/+34
Some pthreads functions use getrlimit and gettimeofday, but these functions are XSI, not base POSIX; this is a namespace issue for dynamic linking as well as static linking. This patch makes them use __getrlimit and __gettimeofday instead - the former needed to be newly exported from libc.so at GLIBC_PRIVATE (and so now needs libc_hidden_proto / libc_hidden_def), the latter was already exported. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17682] * resource/Versions (libc): Add __getrlimit at GLIBC_PRIVATE. * resource/getrlimit.c (__getrlimit): Use libc_hidden_def. * sysdeps/mach/hurd/getrlimit.c (__getrlimit): Likewise. * include/sys/resource.h (__getrlimit): Use libc_hidden_proto. * nptl/nptl-init.c (__pthread_initialize_minimal_internal): Use __getrlimit instead of getrlimit. * nptl/pthread_cond_timedwait.c (__pthread_cond_timedwait): Use __gettimeofday instead of gettimeofday. * nptl/pthread_rwlock_timedrdlock.c (pthread_rwlock_timedrdlock): Likewise. * nptl/pthread_rwlock_timedwrlock.c (pthread_rwlock_timedwrlock): Likewise. * sysdeps/pthread/aio_misc.c (handle_fildes_io): Likewise. * conform/Makefile (test-xfail-POSIX2008/aio.h/linknamespace): Remove variable.

The subsequent fgetws will then try to write at most 'data_len' wchar_t in a buffer with just data_len 'char'. This patch fixes it by allocating the tmpbuf using 'wchar_t' * data_len bytes.

2014-12-04Fix linknamespace h_errno handling.Joseph Myers3-5/+12
Some linknamespace tests were failing because of references to h_errno. References to this symbol should be allowed for XPG4, UNIX98 and XOPEN2K; this patch adds it to the list of allowed data symbols for those standards. (h_errno was removed in the 2008 edition of POSIX, so POSIX2008 and XOPEN2K8 references to it are genuine bugs; fortunately it's not a public data symbol - __h_errno_location is public, TLS h_errno is GLIBC_PRIVATE - so the symbol can simply be renamed to __h_errno to fix those bugs without the ABI complications normally associated with namespace issues for data symbols.) Tested for x86_64. * conform/list-header-symbols.pl (%extra_syms): Add h_errno for XPG4, UNIX98 and XOPEN2K. * conform/Makefile (test-xfail-XOPEN2K/grp.h/linknamespace): Remove variable.

2014-12-04ftell: seek to end only when there are unflushed bytes (BZ #17647)Siddhesh Poyarekar5-10/+108
Currently we seek to end of file if there are unflushed writes or the stream is in write mode, to get the current offset for writing in append mode, which is the end of file. The latter case (i.e. stream is in write mode, but no unflushed writes) is unnecessary since it will only happen when the stream has just been flushed, in which case the recorded offset ought to be reliable. Removing that case lets ftell give the correct offset when it follows an ftruncate. The latter truncates the file, but does not change the file position, due to which it is permissible to call ftell without an intervening fseek call. Tested on x86_64 to verify that the added test case fails without the patch and succeeds with it, and that there are no additional regressions due to it. [BZ #17647] * libio/fileops.c (do_ftell): Seek only when there are unflushed writes. * libio/wfileops.c (do_ftell_wide): Likewise. * libio/tst-ftell-active-handler.c (do_ftruncate_test): New test case.

It seems two of the XFAILed linknamespace tests were completely fixed by some of my recent namespace fixes in combination (although not by any individual one of those fixes relative to the sources used for testing each patch, or that individual fix would also have removed the XFAIL in question).

2014-12-02Fix getifaddrs, freeifaddrs namespace (bug 17668).Joseph Myers6-16/+40
Various objects in glibc bring in ifaddrs.o (via references to __netlink_*) and thereby getifaddrs and freeifaddrs, which are not part of any standard supported by glibc. These should be weak aliases of __getifaddrs and __freeifaddrs; this patch makes them so. (The path by which these functions are brought in is Linux-specific, but it seems less confusing to make all versions of these functions weak aliases rather than only the Linux-specific versions that definitely need it.) Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by this patch). [BZ #17668] * inet/ifaddrs.c (getifaddrs): Rename to __getifaddrs and define as weak alias of __getifaddrs. Use libc_hidden_weak. (freeifaddrs): Rename to __freeifaddrs and define as weak alias of __freeifaddrs. Use libc_hidden_weak. * sysdeps/gnu/ifaddrs.c (getifaddrs): Rename to __getifaddrs and define as weak alias of __getifaddrs. Use libc_hidden_weak.

2014-12-02mips: Do not use jal to reach __libc_start_mainPetar Jovanovic3-3/+13
Since __libc_start_main may not be in the same 256MB-aligned region as the function __start, replace use of jal instruction with la/jalr. This fixes linker issue reported in: https://sourceware.org/bugzilla/show_bug.cgi?id=17601 [BZ #17601] * sysdeps/mips/start.S (__start): Use indirect jump to call __libc_start_main.
2014-12-02Fix warning in nptl/tst-stack4.c.Joseph Myers2-1/+3
This patch fixes a warning in a test that was added since my recent warning cleanup: tst-stack4.c: In function 'dso_process': tst-stack4.c:64:7: warning: format '%i' expects argument of type 'int', but argument 3 has type 'uintptr_t' [-Wformat=] The original variable has type int then is cast to uintptr_t, and from there to void *, to pass it to a thread, so reversing the process by casting to uintptr_t and then to int is natural; this patch does so. Tested for x86_64. * nptl/tst-stack4.c (dso_process): Use int not uintptr_t for t.
2014-12-02Fix -Waddress warnings in nptl/tst-mutex1.c.Joseph Myers4-2/+12
This patch fixes -Waddress warnings in nptl/tst-mutex1.c from comparing the address of an object with NULL (ATTR may either be NULL, or the address of an object when included from other tests, and the warning arises in the latter case). A macro ATTR_NULL is defined alongside ATTR and used for the tests. Tested for x86_64. * nptl/tst-mutex1.c: Include <stdbool.h>. [!ATTR] (ATTR_NULL): New macro. (do_test): Test !ATTR_NULL instead of ATTR != NULL. * nptl/tst-mutexpi1.c (ATTR_NULL): New macro. * nptl/tst-mutexpp1.c (ATTR_NULL): New macro.
