* maint: fix operator precedence in mbrtowc testDaiki Ueno2015-12-282-2/+2
| | | | | | | | | | | This is a fix for test breakage introduced by commit 45228d96; the equality expression must be parenthesized when negated with '!', otherwise we always get: test-mbrtowc.c:49: assertion 'ret == (size_t)(-2)' failed * m4/mbrtowc.m4 (gl_MBRTOWC_EMPTY_INPUT): Negate the entire expression. * m4/mbrlen.m4 (gl_MBRLEN_EMPTY_INPUT): Likewise.

* gnulib-common.m4: fix gl_PROG_AR_RANLIB/AM_PROG_AR clashPavel Raiskup2015-09-251-15/+28
| | | | | | | | | | | | | | | | | | | | | | | | The gl_PROG_AR_RANLIB (it is always called by gl_EARLY) sets AR and ARFLAGS variables. Doing this unconditionally could break later Automake's AM_PROG_AR invocation (at least it's AC_CHECK_TOOLS call to detect correct 'ar' binary). Original purpose of the gl_PROG_AR_RANLIB was only to handle the Amsterdam Compiler Kit, so make the previous code to have effects only on ACK, and rather automatically call the Automake's AM_PROG_AR as soon as possible to decide other cases. References: http://lists.gnu.org/archive/html/bug-gnulib/2015-07/msg00001.html * m4/gnulib-common.m4 (gl_PROG_AR_RANLIB): AC_BEFORE AM_PROG_AR. Set the AR/ARFLAGS to ACK defaults OR call AM_PROG_AR. If neither is possible, keep setting AR/ARFLAGS to reasonable defaults. * gnulib-tool (func_import): Put the gl_USE_SYSTEM_EXTENSIONS right before gl_PROG_AR_RANLIB into gnulib-comp.m4 (if the 'extensions' module is used. * modules/extensions (configure.ac-early): Remove as this snippet is added to gnulib-comp.m4 earlier anyway.
* gc: fix detection of installed libgcrypt versionMats Erik Andersson2015-09-251-10/+12
| | | | | | * m4/gc.m4: Use AM_PATH_LIBCRYPT to test for libcrypt versions at least as recent as 1.4.4. The previously used macro is not available now, since modules were removed in version 1.6.0.

* maint: add coding cookies to non-ASCII sourcesPaul Eggert2015-09-243-3/+3
| | | | | | | | | | | | Otherwise, Emacs might do the wrong thing if run in an he_IL.ISO-8859-8 locale, which an Emacs developer does on occasion. Problem reported by Eli Zaretskii in: http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00966.html Don't bother with test files, as they aren't copied to the Emacs source directory. If this problem affects test files in some other GNU project, we can add coding cookies to the non-ASCII test files later.

* localename: fix link error on IllumosDaiki Ueno2015-07-071-0/+5
| | | | | | | | | Illumos defines __sun, but does not have getlocalename_l nor the equivalent. This partially reverts commit 387c214. * m4/localename.m4 (gl_LOCALENAME): Check if getlocalename_l is available, as well as uselocale. * lib/localename.c [HAVE_USELOCALE && __sun]: Don't fallback to use getlocalename_l if it is not available.
* gnulib-common.m4: change the ARFLAGS default to 'cr'Pavel Raiskup2015-07-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | In some GNU/Linux distributions people started to compile 'ar' binary with --enable-deterministic-archives (binutils project). That, however, in combination with previous autotools long time working default AR{_,}FLAGS=cru causes warnings on such installations: ar: `u' modifier ignored since `D' is the default (see `U') The 'u' option (at least with GNU binutils) did small optimization during repeated builds because it instructed 'ar' to not open/close unchanged *.o files and to rather read their contents from old archive file. However, its removal should not cause a big performance hit for usual workflows. Distributions started using --enable-deterministic-archives knowing that it will disable the 'u', with the benefit of having rather a bit more deterministic builds. Also, to justify this change a bit more, keeping 'u' in ARFLAGS could only result in many per-project changes to override Automake's ARFLAGS default, just to silent such warnings. * m4/gnulib-common.m4 (gl_PROG_AR_RANLIB): Set ARFLAGS='cr' if not set already.
* mgetgroups: port to strict OS XPaul Eggert2015-06-301-34/+1
| | | | | | | The previous fix wasn't working, so use a bigger hammer (Bug#20923). * lib/mgetgroups.c: Ignore -Wpointer-sign diagnostics. (getgrouplist_gids) [HAVE_GETGROUPLIST]: Remove. All uses removed. * m4/mgetgroups.m4 (gl_MGETGROUPS): Revert recent changes.

| | | | | * m4/mgetgroups.m4 (gl_MGETGROUPS): Use more-sensitive -Werror setting if available.
* linkat: fix invalid definition of LINKAT_SYMLINK_NOTSUP on OS XJim Meyering2015-06-291-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It started like this when building coreutils' latest on OS X, invoking ./configure with a nonempty --cache=.cache: lib/linkat.c:46:42: error: operator '||' has no right operand lib/linkat.c: In function 'rpl_linkat': lib/linkat.c:330:27: error: #if with no expression Here's linkat.c's line 46: #if !HAVE_LINKAT || LINKAT_SYMLINK_NOTSUP Here's some context: $ grep linkat_nofoll .cache gl_cv_func_linkat_nofollow=${gl_cv_func_linkat_nofollow=no} $ grep LINKAT_SYM lib/config.h #define LINKAT_SYMLINK_NOTSUP The problem is that m4/linkat.m4's gl_FUNC_LINKAT uses AC_CACHE_CHECK to set LINKAT_SYMLINK_NOTSUP, but that violates a tenet of AC_CACHE_CHECK: it must have no side effect other than setting its cache variable. What happens is that when the cache is set, we'd skip the code in that AC_CACHE_CHECK call, and leave LINKAT_SYMLINK_NOTSUP defined to whatever value it happened to have in configure's environment. In my case, it was not defined, so this later code: AC_DEFINE_UNQUOTED([LINKAT_SYMLINK_NOTSUP], [$LINKAT_SYMLINK_NOTSUP], [Define to 1 if linkat can create hardlinks to symlinks]) would emit code with an empty RHS. * m4/linkat.m4 (gl_FUNC_LINKAT): Move the setting of $LINKAT_SYMLINK_NOTSUP out of the AC_CACHE_CHECK code block.
* mgetgroups: port to strict OS XPaul Eggert2015-06-291-1/+37
| | | | | | | | | | * doc/glibc-functions/getgrouplist.texi (getgrouplist): Document the getgrouplist problem. * lib/mgetgroups.c (getgrouplist_gids) [HAVE_GETGROUPLIST]: New macro. (mgetgroups): Use it. * m4/mgetgroups.m4 (gl_MGETGROUPS): Check for OS X signature for getgrouplist.
* file-has-acl: fix build on Mac OS X 10Pádraig Brady2015-06-021-5/+19
| | | | | | | | | | | | This reverts commit f1b37e3a which doesn't work on Mac OS X >= 10.4 which has an incompatible 6 parameter getxattr() call. * doc/glibc-functions/getxattr.texi: Mention the divergent getxattr() call on Mac OS X >= 10.4. * doc/glibc-functions/fgetxattr.texi: Likewise. * lib/file-has-acl.c: Revert to more complete combined check. * m4/acl.m4 (gl_FILE_HAS_ACL): Likewise. Reported by Jack Howarth.

* readlinkat: avoid OS X 10.10 trailing slash bugPádraig Brady2015-05-311-4/+14
| | | | | | | | | | | | | * 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.
* linkat: avoid OS X 10.10 trailing slash with symlink bugPádraig Brady2015-05-291-2/+12
| | | | | | | | | | | | | | 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.
* unlinkat: handle ignoring of ".." on Darwin 14Pádraig Brady2015-05-281-0/+1
| | | | | | | | | | | * 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.
* file-has-acl: Split feature tests again (Bug#20667)Andreas Gruenbacher2015-05-271-19/+5
| | | | | | | | * lib/file-has-acl.c: Instead of testing for XATTR_NAME_POSIX_ACL_ACCESS and XATTR_NAME_POSIX_ACL_DEFAULT, define them when needed. * m4/acl.m4 (gl_FILE_HAS_ACL): With that, Paul's GETXATTR_WITH_POSIX_ACLS change shouldn't be needed anymore.
* stdio: limit __gnu_printf__ witness to gcc 4.4+Eric Blake2015-05-261-2/+3
| | | | | | | | | | | | If we start adding more places that need to conditionally label functions with __gnu_printf__, it will be nicer if the logic for determining that gcc even supports that attribute is done once up front rather than in each caller. * lib/error.h (_GL_ATTRIBUTE_SPEC_PRINTF): Move gcc version probe... * m4/stdio_h.m4 (gl_STDIO_H): ...here. Signed-off-by: Eric Blake <eblake@redhat.com>
* stdio: fix probe on mingw under gcc 5.1Eric Blake2015-05-261-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | Per https://gcc.gnu.org/gcc-5/porting_to.html, gcc 5.1 intentionally changed the preprocessor to emit multiple lines, rather than one line, when expanding text that includes literal markers combined with a macro expansion obtained from a header. This in turn breaks the probe for whether mingw headers support GNU-style "lld" for PRIdMAX, as the probe text was no longer on one line. This patch changes from grepping preprocessor output (with its indeterminate layout due to differences in preprocessors) to instead using a compile-time check of the length of the macro expansion. It feels a bit gross, but the grossness is limited to mingw, which is the only platform where using __gnu_printf__ instead of __printf__ will make a difference. Based on a report by Suren Hajyan. * m4/stdio_h.m4 (gl_STDIO_H): Change to compile test, to work around new gcc preprocessor rules. Signed-off-by: Eric Blake <eblake@redhat.com>
* extern-inline: no need for workaround in GCC 5.1Paul Eggert2015-04-291-2/+3
| | | | | | | | * doc/extern-inline.texi (extern inline): * m4/extern-inline.m4 (gl_EXTERN_INLINE): GCC bugs 54113 and 63877 are fixed in GCC 5.1, so don't work around these bugs in GCC 5.1 and later. Maybe in a decade or two we can remove these workarounds.
* file-has-acl: port to CentOS 6Paul Eggert2015-04-261-5/+19
| | | | | | | | | | | | Problem reported by Tom G. Christensen in: http://lists.gnu.org/archive/html/bug-gnulib/2015-04/msg00074.html * lib/file-has-acl.c: Use GETXATTR_WITH_POSIX_ACLS instead of a combination of HAVE_SYS_XATTR_H, HAVE_LINUX_XATTR_H, and HAVE_GETXATTR. * m4/acl.m4 (gl_FILE_HAS_ACL): Test fot the entire combination of linux/xattr.h, sys/xattr.h, getxattr, XATTR_NAME_POSIX_ACL_ACCESS, and XATTR_NAME_POSIX_ACL_DEFAULT, since that's what what file-has-acl.c actually needs.
* file-has-acl: new module, split from aclPaul Eggert2015-04-241-25/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | And add a new module file-has-acl-tests to match. I ran into a problem with the recent changes to the acl module, as they introduced a typo 'test use_xattrs = 0' into 'configure'. When using the fixed version with Emacs, I discovered that file-has-acl wasn't separated out well enough for Emacs (e.g., it had multiple libraries, but needed only one), so I fixed that too. * NEWS: Document this incompatible change. * modules/file-has-acl, modules/file-has-acl-tests: New files. * m4/acl.m4 (gl_FUNC_ACL_ARG): New macro, split from gl_FUNC_ACL. Initialize gl_need_lib_has_acl. (gl_FUNC_ACL): Require it. Simplify use of 'test'. Set LIB_HAS_ACL if gl_need_lib_has_acl. Move the file-has-acl.c-relevant stuff to ... (gl_FILE_HAS_ACL): ... this new macro. Rewrite to fix 'test use_xattrs = 0' typo, and omit some needless work. Set gl_need_lib_has_acl=1 if we'll need LIB_HAS_ACL to be set when gl_FUNC_ACL is called. * modules/acl (Files, lib_SOURCES): Remove lib/file-has-acl.c. (Link): Remove $(LIB_HAS_ACL). * modules/acl-tests (Files, Depends-on, configure.ac, TESTS) (check_PROGRAMS): Move stuff relevant to file-has-acl to modules/file-has-acl-tests. (test_file_has_acl_LDADD): Move to modules/file-has-acl-tests.
* manywarnings: add GCC 5.1 warningsPaul Eggert2015-04-241-3/+20
| | | | | | | | | | | | | | | | | * build-aux/gcc-warning.spec: Add -Wabi=, -Warray-bounds, -Warray-bounds=, -Wc++14-compat, -Wc90-c99-compat, -Wc99-c11-compat, -Wshadow-ivar, -Wsized-deallocation, -Wsuggest-override, -Wuse-without-only. Change -Wnormalized=... operands to match 5.1. * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add -Wbool-compare, -Wchkp, -Wdesignated-init, -Wdiscarded-array-qualifiers, -Wdiscarded-qualifiers, -Wformat-signedness, -Wincompatible-pointer-types, -Wint-conversion, -Wlogical-not-parentheses, -Wmemset-transposed-args, -Wodr, -Wshift-count-negative, -Wshift-count-overflow, -Wsizeof-array-argument, -Wsuggest-final-methods, -Wsuggest-final-types, -Wswitch-bool. Remove -Warray-bounds, and add -Warray-bounds=2 as a special case.
* lstat: fix cross-compilation 'ln -s' problemPaul Eggert2015-04-211-25/+23
| | | | | | | | * m4/lstat.m4 (gl_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Have the test program call 'symlink' rather than a separate script run 'ln -s'; this is more likely to work in cross-compilation environments. Reported by Pavel Fedin in: http://lists.gnu.org/archive/html/bug-gnulib/2015-04/msg00060.html
* acl: On Linux, check for acls without libaclAndreas Gruenbacher2015-04-151-0/+17
| | | | | | | | | | | | | On Linux, use the getxattr syscall instead of the acl_extended_file libacl library function to check for the presence of acls, avoiding a library dependency. * lib/file-has-acl.c: Include xattr headers if we have them. (file_has_acl): On Linux, use getxattr(). * m4/acl.m4 (gl_FUNC_ACL): Define LIB_HAS_ACL as the libraries to link with for file_has_acl(). Check for xattr headers and getxattr(). * modules/acl: Add a dep on the stdbool module which was already needed. Add the new reduced dependency LIB_HAS_ACL reference.

* mountlist: remove dependency on libmountPádraig Brady2015-04-031-21/+2
| | | | | | | | | | | | * lib/mountlist.c (read_file_system_list): Parse /proc/self/mountinfo directly, rather than depending on libmount, which has many dependencies due to its dependence on libselinux, as detailed at: http://lists.gnu.org/archive/html/bug-gnulib/2015-01/msg00063.html Note we restrict this to __linux__ as that's probably where this interface will remain. If ever porting, it would be best to first pull the makedev() wrapper from coreutils to a gnulib module. Note also we don't add a getline dependency to the mountlist module, as all Linux versions are sufficient.

| | | | | | | | | | | | | | | | | Problem reported by Kevin Cernekee in: http://lists.gnu.org/archive/html/bug-gnulib/2015-02/msg00092.html * doc/glibc-functions/getdtablesize.texi (getdtablesize): Mention that getdtablesize doesn't work on Android. * lib/getdtablesize.c: Use getrlimit substitute only if getdtablesize is declared. This should suffice for Cygwin while not breaking Android. * m4/dup2.m4 (gl_FUNC_DUP2): * m4/fcntl.m4 (gl_FUNC_FCNTL): Prefer sysconf (_SC_OPEN_MAX) to getdtablesize, as the former is standardized but the latter is not, and sysconf works on Android. * m4/getdtablesize.m4 (gl_FUNC_GETDTABLESIZE): Also check that getdtablesize is declared. This removes the need for a special case for Android.
* net_if: Handle content-free <net/if.h> system headersKevin Cernekee2015-02-111-1/+2
| | | | | * m4/net_if_h.m4: Check to make sure <net/if.h> actually defines struct if_nameindex. If not, enable the replacement header.
* linkat_nofollow: Add fallback case for cross compilingKevin Cernekee2015-02-111-2/+16
| | | | * m4/linkat.m4: Guess no for Darwin, yes otherwise.
* getdtablesize: Fix Android buildKevin Cernekee2015-02-111-1/+3
| | | | | | | * m4/getdtablesize.m4: Add Android case to host OS check. Recent NDK versions have this symbol in the .so library (at least 32-bit platforms) but are missing the declaration in the header file, causing the m4 logic to guess incorrectly.
* Assume unbroken ungetc() on AndroidKevin Cernekee2015-02-111-2/+3
| | | | | | * m4/ungetc.m4: Add Android case to host OS check. The ungetc() test case passed when running on an Android host, and the code hasn't really changed since 2009.
