Bruno Haible 674d5d1d 2009-12-23T03:41:34 wchar: Diagnose broken combination of glibc and gcc versions and flags.
Eric Blake 4e86671a 2009-12-21T11:14:18 getsubopt: work around cygwin bug On cygwin, compiling with -DGNULIB_POSIXCHECK failed because the getsubopt link warning definition interfered with the inclusion of the system header. The fix, as always in these types of problems, is to ensure that system headers are completely included before doing any overrides. * lib/stdlib.in.h (includes): Move unistd inclusion sooner, to avoid conflicting with system getsubopt. * doc/posix-functions/getsubopt.texi (getsubopt): Document the bug.

Eric Blake 3c8bb39b 2009-12-02T15:48:08 test-getopt: test stderr behavior Portions of this commit are commented out because they tickle glibc bugs. For a real-life example of the bug: $ env -ua -: env: invalid option -- : Try `env --help' for more information. $ env -: env: invalid option -- : Try `env --help' for more information. $ env -+ env: invalid option -- + Try `env --help' for more information. $ env -ua -+ Try `env --help' for more information. Notice that when -+ is not given as the first argument, the error message is mistakenly suppressed. * modules/getopt-posix-tests (Depends-on): Add dup2. * tests/test-getopt.c (ASSERT): Avoid stderr. (main): Move stderr to a temporary file. * tests/test-getopt.h (getopt_loop): No longer manipulate opterr. Instead, add parameter to inform caller if output occurred.

Eric Blake a8ec28b6 2009-12-01T17:21:34 test-getopt: enhance test Add coverage of optind==0 for getopt_long, since coreutils depends on it.

Eric Blake c0c5acfb 2009-11-27T17:47:21 getopt-gnu: flush out another BSD bug POSIX requires 'echo foo > bar; m4 -Dfoo=1 bar -Dfoo=2 bar' to output '1' then '2'. To achieve this, m4 relies on the GNU getopt{,_long} extension of a leading '-'. However, BSD getopt fails to honor this extension when POSIXLY_CORRECT. Also, BSD getopt fails to reparse POSIXLY_CORRECT from the environment even when a reset is requested (whether by optreset=1 or by optind=0). * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Test for the bug. * tests/test-getopt.c (main): Check POSIXLY_CORRECT first, to flush out BSD bug. * tests/test-getopt.h (test_getopt): End lists with NULL. * tests/test-getopt_long.h (test_getopt_long): Likewise.

Work around it by using chmod, which does not have this bug. Unfortunately, lchown has the same bug, but OpenBSD 4.0 lacks lchmod and lutimes, so there is no way to affect ctime without unlinking and recreating the symlink, which is too dangerous. * lib/chown.c (rpl_chown): Work around the bug. * lib/lchown.c (rpl_lchown): Attempt to do likewise. * m4/chown.m4 (gl_FUNC_CHOWN): Test for ctime bug. * m4/lchown.m4 (gl_FUNC_LCHOWN): Check for lchmod. * modules/chown (Depends-on): Add stdbool. * modules/lchown (Depends-on): Likewise. * doc/posix-functions/chown.texi (chown): Document the bug. * doc/posix-functions/lchown.texi (lchown): Likewise. * tests/test-lchown.h (test_chown): Relax test.

The gnulib replacement for void unsetenv did not do validation, and the replacement for setenv was out of sync with glibc. Also, some BSD implementations of setenv("a","==",1) eat the leading '='.

But in the rare case that GETGROUPS_T is still int but gid_t is short, the user should not have to uglify their code; let the replacement hide all the magic. Tested by configuring with ac_cv_type_getgroups=uint64_t on a platform with 32-bit gid_t, and ignoring compiler warnings.

Eric Blake 8c871c07 2009-10-20T16:47:36 utimensat: work around Solaris 9 bug utimes("file/",times) mistakenly succeeds. This commit doesn't fix utimes, but does make utimensat be careful before calling utimes. The test is now enhanced to test trailing slashes and directories. Meanwhile, cygwin 1.5 stat() on a directory changes atime (it does a readdir under the hood to populate st_nlink), so only mtime of a directory is reliable enough for testing.

Eric Blake 99ad8ac7 2009-09-11T12:18:10 canonicalize, canonicalize-lgpl: use <stdlib.h> Match current gnulib conventions of glibc functions being declared in the same header as glibc. This makes it easier to replace broken canonicalize_file_name. canonicalize still requires "canonicalize.h" because canonicalize_filename_mode is not in glibc. With this patch, canonicalize-lgpl always provides realpath and canonicalize_file_name, while canonicalize can provide canonicalize_file_name but not realpath; if both modules are in use, canonicalize_file_name comes from the LGPLv2+ sources, but the testing comes from canonicalize. * modules/canonicalize-lgpl (Files): Drop canonicalize.h.
