* hash, mgetgroups: drop xalloc dependencyEric Blake2011-04-281-0/+3
| | | | | | | | | | | | | | | | | | | | | Rely on the new xalloc-oversized module to avoid requiring xalloc-die for functions documented as returning NULL on potential allocation overflow. * lib/hash.c (includes): Adjust includes. * lib/mgetgroups.c (includes): Likewise. (xgetgroups): Move... * lib/xgetgroups.c: ...to new file. * modules/xgetgroups: New file, split from... * modules/mgetgroups: ...here.

* save-cwd: reduce default dependencyEric Blake2011-04-271-0/+5
| | | | | | | | | | | | | | | | | | | | | save-cwd generally needs only a working fchdir or a working getcwd(NULL,0). If you are not worried about directories whose absolute name is longer than PATH_MAX, then reducing the default dependencies reduces the bulk for this module. However, there are cases where neither function works on Linux (an unreadable but searchable directory can be opened by O_SEARCH, except that Linux doesn't implement that yet; and Linux getcwd() has issues with long absolute names which glibc does not work around but which the full-blown getcwd module does). So someone desiring a truly robust solution needs to import the 'getcwd' module at the same time as 'save-cwd'. * modules/save-cwd (Depends-on): Use getcwd-lgpl. * lib/save-cwd.c: Update comments. * NEWS: Document the semantic change.

* dirname: move m4/dos.m4 functionality into lib/dosname.hPaul Eggert2011-02-251-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | m4/dos.m4 needs to go. It laboriously invokes the C compiler, and extracts symbols from it, puts them into config.h; but it's much easier to use the symbols directly. filename.h already does this, but it disagrees with dos.m4 in some respects. This patch introduces a different include file dosname.h that packages up dos.m4, and then later we can work on merging filename.h and dosname.h. Applications that need only the easy-to-configure symbols should consider including dosname.h rather than dirname.h. * NEWS: Mention incompatible changes. * m4/dos.m4: Remove. * lib/dosname.h, modules/dosname: New files. * lib/dirname.h (ISSLASH, FILE_SYSTEM_PREFIX_LEN): (FILE_SYSTEM_DRIVE_PREFIX_CAN_BE_RELATIVE): (IS_ABSOLUTE_FILE_NAME, IS_RELATIVE_FILE_NAME): Move to lib/dosname.h. * lib/at-func.c, lib/at-func2.c, lib/openat.c, lib/savewd.c: Include dosname.h, not dirname.h. * lib/rmdir.c, lib/stat.c, lib/unlink.c, lib/unlinkat.c: Include dosname.h, for definitions of symbols like ISSLASH that used to be in config.h. * m4/dirname.m4 (gl_DIRNAME_LGPL): Do not require gl_AC_DOS. * m4/rmdir.m4 (gl_FUNC_RMDIR): Likewise. * m4/stat.m4 (gl_FUNC_STAT): Likewise. * m4/unlink.m4 (gl_FUNC_UNLINK): Likewise. * modules/dirname-lgpl (Files): Omit m4/dos.m4. * modules/rmdir (Files): Likewise. * modules/stat (Files): Likewise. * modules/unlink (Files): Likewise. * modules/dirname-lgpl (Depends-on): Add dosname. * modules/lstat (Depends-on): Likewise. * modules/openat (Depends-on): Likewise. * modules/rmdir (Depends-on): Likewise. * modules/savewd (Depends-on): Likewise. * modules/stat (Depends-on): Likewise. * modules/unlink (Depends-on): Likewise. * modules/openat (Depends-on): Remove dirname-lgpl. * modules/savewd (Depends-on): Likewise. * tests/test-dirname.c: Do not use removed symbols like FILE_SYSTEM_BACKSLASH_IS_FILE_NAME_SEPARATOR.

Do tests in the same order as they're needed for getloadavg.c. Omit setgid-related tests that generate symbols KMEM_GROUP, NEET_SETGID, GETLOADAVG_PRIVILEGED; nobody seems to use those any more. Do only the tests that are needed to see whether the system has getloadavg, moving the other tests into ... (gl_PREREQ_GETLOADAVG): ... here. Do not define obsolete symbol NLIST_NAME_UNION; nobody should be using it. Do not define symbols C_GETLOADAVG and HAVE_GETLOADAVG; they're no longer relevant, as the user of this module shouldn't care how getloadavg is implemented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These days, most systems already declare getgroups with gid_t*. 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.

* same-inode: make SAME_INODE tri-state, to port to mingwEric Blake2009-09-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mingw has the annoying habit (already documented in doc/posix-functions/*stat) that st_ino is always 0. This means that naive uses of SAME_INODE(a,b) would succeed, even on distinct files. Here's an analysis of all gnulib modules that used the macro before this commit: chdir-safer is safe - SAME_INODE protected by HAVE_READLINK cycle-check - mingw has no dir hard links and no symlinks, so no directory cycles can occur, and we should ignore -1 fts - SAME_INODE protected by FTS_DEBUG hash-triple - using -1 gives more hash collisions, but the results are still correct openat-proc - SAME_INODE protected by stat("/proc/self") same - no dir cycles, so files are only same with identical name link-follow.m4 - configure test already correct on mingw test-canonicalize* - test already passes on mingw test-[l]stat - test already passes on mingw * NEWS: Mention this change. * lib/same-inode.h (same-inode.h): Recognize mingw limitation of st_ino always being 0. * lib/cycle-check.h (CYCLE_CHECK_REFLECT_CHDIR_UP): Update caller. * lib/cycle-check.c (cycle_check): Likewise. * lib/same.c (same_name): Likewise.

* canonicalize, canonicalize-lgpl: use <stdlib.h>Eric Blake2009-09-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
