* getcwd: support coreutils betterPaul Eggert2013-02-201-1/+1
| | | | | | | | | | | | | | Like strtod, getcwd incorrectly referred to HAVE_RAW_DECL_GETCWD, but this might not be correct in coreutils, which disables the raw decl checks. Problem reported by Nagendra in <http://bugs.gnu.org/10305#192>. * lib/getcwd.c (__getcwd): Do not depend on HAVE_RAW_DECL_GETCWD. * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Test the getcwd function, not any macro, since getcwd.c wants the function. * m4/getcwd.m4 (gl_FUNC_GETCWD): Don't define HAVE_MINIMALLY_WORKING_GETCWD if the code doesn't compile, as might happen if there's a macro but no function.
* getcwd: break fdopendir + save_cwd recursive loop (Bug#13516)Paul Eggert2013-02-031-3/+3
| | | | | | | | | | | | | | | Reported for OS X 10.8.2 by Assaf Gordon in <http://bugs.gnu.org/13516>. * lib/getcwd.c (HAVE_OPENAT_SUPPORT): Do not define if !HAVE_OPENAT && !HAVE_FDOPENDIR. * m4/getcwd-abort-bug.m4: Reformat to match test-getcwd.c so that they can be kept in sync more easily. Avoid PATH_MAX test on the Hurd. Sync from test-getcwd.c for errno tests after mkdir or chdir failure. * tests/test-getcwd.c (HAVE_OPENAT_SUPPORT): New macro, from lib/getcwd.c.

| | | | | | | | | | | | | | | | | * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Require AC_CANONICAL_HOST. Assign exit code 31 to the bug seen on AIX 5.1..7.1. Use a different value for gl_cv_func_getcwd_path_max. Move the definition of HAVE_PARTLY_WORKING_GETCWD from here... * m4/getcwd.m4 (gl_FUNC_GETCWD): ... to here. Invoke gl_FUNC_GETCWD_PATH_MAX also when $gl_cv_func_getcwd_null is 'no'. Define HAVE_MINIMALLY_WORKING_GETCWD. * lib/getcwd.c (__getcwd): Don't use the system's getcwd on platforms where it is not even minimally working, that is, on AIX. * tests/test-getcwd.c (test_long_name): Distinguish the same cases as m4/getcwd-path-max.m4. (main): Update exit code computation. * doc/posix-functions/getcwd.texi: Mention list of platforms where getcwd does not handle long file names.
* getcwd: don't fail in a deep directory on a system without openatJim Meyering2011-09-191-3/+4
| | | | | | | | | | | | Before this change, getcwd would fail when called from a directory of depth PATH_MAX / 3 or greater. That was due to the fact that the non-openat implementation used "..", "../..", "../../..", etc. to access ancestor directories. With too many, that string would be longer than PATH_MAX. * lib/getcwd.c (HAVE_OPENAT_SUPPORT): Define also when we are using gnulib's openat replacement. * m4/openat.m4: Set GNULIB_OPENAT, so getcwd.c knows when we're using the replacement function.
* getcwd: fix test failures on mingwEric Blake2011-08-171-1/+1
| | | | | | | | | | | | | | | | | The GPL getcwd replacement now kicks in for mingw thanks to the signature check, but does not have to do anything. However, because the code was not taking an early exit for ERANGE when a buffer size was given, it instead tried to second-guess mingw's cwd algorithm, which doesn't work. After fixing that, the tests still failed, even though mingw getcwd doesn't have any problems with long paths (since they can't be created in the first place). * lib/getcwd.c (__getcwd): Early exit for ERANGE. * tests/test-getcwd.c (test_abort_bug, test_long_name): Don't fail test if long directory cannot be created, and allow mingw errno.

| | | | | | | | | | | | | | | | | * lib/pathmax.h (PATH_MAX): Leave it undefined on GNU/Hurd. * lib/chdir-long.h: Include pathmax.h. * lib/clean-temp.c (PATH_MAX): Remove code that is done by pathmax.h. * lib/getcwd.c: Include pathmax.h instead of <limits.h>. (PATH_MAX): Remove code that is done by pathmax.h. * lib/canonicalize.c (PATH_MAX): Provide a fallback value. * lib/tmpfile.c: Add a comment. * m4/pathmax.m4 (gl_PATHMAX): Don't test for pathconf. * modules/chdir-long (Depends-on): Add pathmax. * modules/getcwd (Depends-on): Add pathmax. * tests/test-getcwd.c (test_abort_bug): Avoid syntax error when PATH_MAX is not defined. * doc/posix-headers/limits.texi: Mention the pathmax module. * NEWS: Mention the change.
* maint: update almost all copyright ranges to include 2011Jim Meyering2011-01-011-1/+1

* fts, getcwd, glob: audit for dirfd returning -1Paul Eggert2010-09-141-2/+0
| | | | | | | | | | | | | | * lib/fts.c (opendir): Remove #define; no longer used. (opendirat): New arg PDIR_FD. All callers changed. (fts_build, _opendir2): Use new opendirat to avoid the need for dirfd, or for checking whether dirfd returns a negative value. Don't use opendir; always use openat followed by fdopendir. * lib/getcwd.c (__getcwd): Don't reset fd; fdopendir no longer clobbers it. * lib/glob.c (link_exists_p): Add comment explaining why dirfd never returns -1 here. * modules/fts (Depends-on): Remove dirfd. * modules/getcwd (Depends-on): Likewise.
* getcwd: on Solaris, work better if ancestors are inaccessiblePaul R. Eggert2010-07-141-8/+25
| | | | | | | | | | | | | | | | * lib/getcwd.c (__getcwd): If getcwd returns EINVAL for zero buffer and size, try again with a large buffer. This works better on Solaris, since its getcwd succeeds even if the path to the root is inaccessible, and this is helpful in common cases such as .zfs hidden directories. Problem reported by J Chapman Flack in http://lists.gnu.org/archive/html/bug-tar/2010-06/msg00000.html Use system getcwd if it's declared, not merely if it's partly working; use the partly-working test only to avoid needless effort if the system getcwd fails. * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Omit comment that was already obsolete and is now even more obsolete. * modules/getcwd (Depends-on): Depend on strdup, since __getcwd now might call strdup.
* update nearly all FSF copyright year lists to include 2010Jim Meyering2010-01-011-1/+1
| | | | | Use the same procedure as for 2009, outlined in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/20081

* getcwd: minor cleanupsEric Blake2009-09-071-15/+1
| | | | | | | * lib/getcwd.c (AT_FDCWD): Delete; rely on <fcntl.h> instead. (is_ENAMETOOLONG): Delete; ENAMETOOLONG is portable. Signed-off-by: Eric Blake <ebb9@byu.net>
* backupfile, chdir-long, fts, savedir: make saferEric Blake2009-09-021-2/+6
| | | | | | | | | | | | | | | | | | | * lib/backupfile.c (includes): Use "dirent--.h", since numbered_backup can write to stderr during readdir. * lib/savedir.c (includes): Likewise. * lib/chdir-long.c (includes): Use "fcntl--.h", since openat emulation can write to stderr on failure. * lib/fts.c (includes) [!_LIBC]: Likewise for opendir and openat. * lib/getcwd.c: Document why opendir_safer is unused. * lib/glob.c: Likewise. * lib/scandir.c: Likewise. * lib/openat-proc.c: Likewise, for open_safer. * modules/backupfile (Depends-on): Add dirent-safer. * modules/savedir (Depends-on): Likewise. * modules/fts (Depends-on): Add dirent-safer and openat-safer. * modules/chdir-long (Depends-on): Add openat-safer.

* getcwd.c: Use a more readable witness: HAVE_OPENAT_SUPPORTPetr Salinger2007-12-171-9/+12
| | | | * lib/getcwd.c: Define and use HAVE_OPENAT_SUPPORT, in place of AT_FDCWD.
* Port to GNU/kFreeBSD - FreeBSD kernel + GNU libc,Jim Meyering2007-12-171-0/+5
| | | | | | | which has no openat syscall, yet <fcntl.h> does define AT_FDCWD. * lib/getcwd.c: Undef AT_FDCWD if there is no openat function. * modules/getcwd (Depends-on): Add openat. Reported by Petr Salinger.
* Use rpl_ prefix for functions, so as to avoid endless recursions in weird cases.Bruno Haible2007-10-171-1/+1

* * lib/getcwd.c (__getcwd): Remove redundant comparison of buf to NULL.Paul Eggert2007-03-191-1/+1
| | | | If size is zero here, buf must be zero.
* * lib/getcwd.c (__getcwd): Undo previous change; it mishandledPaul Eggert2007-02-211-24/+18
| | | | | | | long unreadable paths in GNU/Linux. Problem reported by Andreas Schwab in <http://lists.gnu.org/archive/html/bug-gnulib/2007-02/msg00261.html>. I'll try to think of a better way to fix the Solaris problem.
* * lib/getcwd.c (__getcwd): Don't assume getcwd (NULL, 0) worksPaul Eggert2007-02-211-18/+24
| | | | | | like glibc; on Solaris 10, it fails with errno == EINVAL. POSIX says the behavior is unspecified if the first argument is NULL, so play it safe and never pass NULL to the system getcwd.
* Minor fixups to port to Solaris 10 with Sun C 5.8.Paul Eggert2007-02-211-0/+1
| | | | | | | | * lib/getcwd.c [!_LIBC]: Include dirfd.h, since we use dirfd. * modules/getcwd (Depends-on): Add dirfd. * lib/putenv.c (putenv): #undef it. (rpl_putenv): New decl. (malloc, free): Include <stdlib.h> rather than prototyping separately.
* Don't use FD after a successful "fdopendir (fd)".Jim Meyering2007-02-191-0/+2
| | | | | * lib/getcwd.c (__getcwd) [AT_FDCWD]: fdopendir (fd) usually closes fd. Reset it by calling dirfd on the just-obtained DIR*.
