b2e2010c 2010-01-01 10:31:12 update nearly all FSF copyright year lists to include 2010 Use the same procedure as for 2009, outlined in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/20081
e4ee1420 2009-12-16 10:07:13 fcntl: use to simplify other modules Let fcntl do the work, instead of copying code into other modules. * modules/cloexec (Depends-on): Add fcntl. * modules/fchdir (Depends-on): Likewise. * modules/fd-safer-flag (Depends-on): Likewise. * modules/unistd-safer (Depends-on): Likewise. * modules/dup3 (configure.ac): Set module indicator. * m4/fchdir.m4 (gl_FUNC_FCHDIR): Replace fcntl if fchdir is missing. * lib/fchdir.c (_gl_register_dup): Fix comment. * lib/cloexec.c (dup_cloexec): Simplify, by relying on fcntl. * lib/dup-safer.c (dup_safer): Likewise. * lib/dup-safer-flag.c (dup_safer_flag): Likewise. * lib/dup3.c (dup3): Likewise. * tests/test-fchdir.c (main): Enhance test. Fixes a dup_cloexec bug reported by Ondřej Vašík. Signed-off-by: Eric Blake <ebb9@byu.net>
a226e8ae 2009-12-09 12:11:36 fchdir: Optimize away rpl_fstat when possible.
e29e19dc 2009-12-09 11:49:30 fchdir: Update comment.
aeb9a8a8 2009-12-08 10:23:27 fchdir: avoid memory leak on re-registration. Some code paths (such as dup3) could overwrite one registered directory fd with another, and must not leak the old name. * lib/fchdir.c (ensure_dirs_slot): Avoid memory leak. Signed-off-by: Eric Blake <ebb9@byu.net>
2966d0d2 2009-12-08 06:13:05 fchdir: fix logic bugs Configuring with ac_cv_func_fchdir=no on a system that has fchdir and where open handles directories, just to test out the replacement capabilities, uncovered an m4 test bug and a link failure on rpl_fstat. * m4/fchdir.m4 (gl_FUNC_FCHDIR): Fix logic bug. * tests/test-fchdir.c (main): Enhance test. * lib/fchdir.c (rpl_fstat): Always provide if fchdir replacement is in use. Signed-off-by: Eric Blake <ebb9@byu.net>
1506e414 2009-10-13 09:25:30 fchdir: avoid infinite recursion in mingw rpl_fstat, needed only on mingw when using fchdir, should not call itself. * lib/fchdir.c (rpl_fstat): Call system fstat, rather than recursing. Signed-off-by: Eric Blake <ebb9@byu.net>
881b91b9 2009-10-02 22:32:45 fchdir: avoid compiler warning Using fchdir without canonicalize-lgpl gave a warning. * lib/fchdir.c (canonicalize_file_name) [!HAVE_CANONICALIZE_FILE_NAME]: Avoid compiler warning on mingw. Signed-off-by: Eric Blake <ebb9@byu.net>
a8cf3a87 2009-10-02 13:47:43 maint: cleanup whitespace in recent commits * lib/fchdir.c (get_name): Remove tabs. Reported by Jim Meyering. Signed-off-by: Eric Blake <ebb9@byu.net>
2763d20e 2009-10-02 12:05:02 rename, fchdir: don't ignore chdir failure Although we just checked that chdir(cwd) worked, there is a race where it could disappear while we are temporarily away. If that happens, forcefully give up rather than proceeding in the wrong directory. * lib/fchdir.c (get_name): Abort on unexpected chdir failure. * lib/rename.c (rpl_rename) [W32]: Likewise. (rpl_rename) [RENAME_DEST_EXISTS_BUG]: Avoid one case of losing an empty destination directory if source cannot be renamed, although there is still possibility for failure. * doc/posix-functions/rename.texi (rename): Document the race. Reported by Jim Meyering. Signed-off-by: Eric Blake <ebb9@byu.net>
657fb89d 2009-09-23 20:33:40 fchdir: another mingw fix canonicalize_file_name does not understand drive letters or backslash. The only reason openat required it was to make fchdir get the canonical name of a directory. But we can do the same trick with chdir and getcwd. With this fix, fchdir(open("..",O_RDONLY)) finally does the right thing on mingw. * modules/fchdir (Depends-on): Drop canonicalize-lgpl. * lib/fchdir.c (get_name): New helper method; skips canonicalize on mingw (where it has not yet been ported), and make it optional elsewhere. (_gl_register_fd): Use it. Signed-off-by: Eric Blake <ebb9@byu.net>
ed613b9e 2009-09-19 11:21:19 canonicalize-lgpl: adjust clients to use correct header * m4/canonicalize.m4 (gl_FUNC_CANONICALIZE_FILENAME_MODE) (gl_CANONICALIZE_LGPL): Use correct shell quoting. * modules/relocatable-prog-wrapper (Files): Drop canonicalize.h. * lib/fchdir.c (includes): Use <stdlib.h>, not "canonicalize.h". * lib/progreloc.c (includes): Likewise. Signed-off-by: Eric Blake <ebb9@byu.net>
eeb36a48 2009-09-01 10:05:44 fdopendir: optimize on mingw * lib/unistd.in.h (_gl_directory_name): New prototype. * lib/fchdir.c (_gl_directory_name): Implement it. (fchdir): Use it to simplify implementation. * lib/fdopendir.c (fdopendir) [REPLACE_FCHDIR]: Use metadata from fchdir, when available, to avoid calling [f]chdir(). Signed-off-by: Eric Blake <ebb9@byu.net>
4475e25b 2009-08-31 14:20:03 fchdir: simplify error handling, and support dup3 * modules/fchdir (Depends-on): Use strdup-posix, not strdup.

(_gl_register_dup): New function. (_gl_unregister_fd, rpl_opendir, rpl_dup): Update callers.

(rpl_dup2_fchdir): Delete prototype. * lib/open.c (open): Update caller. * lib/dup2.c (dup2): Track fchdir metadata. * lib/dup3.c (dup3): Likewise. * m4/dup2.m4 (gl_REPLACE_DUP2): New macro. * m4/fchdir.m4 (gl_FUNC_FCHDIR): Use it. Signed-off-by: Eric Blake <ebb9@byu.net>
0a9873c5 2009-09-01 10:06:44 fchdir: fix off-by-one bug in previous patch * lib/fchdir.c (rpl_fstat): Use correct bounds. (_gl_unregister_fd): Delete useless if. Signed-off-by: Eric Blake <ebb9@byu.net>
8fc864a0 2009-08-31 06:09:08 fchdir: port to mingw * m4/fchdir.m4 (gl_FUNC_FCHDIR): Check for mingw bug. * lib/open.c (open) [FCHDIR_REPLACEMENT]: If directories can't be opened, then use a substitute. * lib/sys_stat.in.h (fstat) [REPLACE_OPEN_DIRECTORY]: Declare replacement. * lib/fchdir.c (fstat) [REPLACE_OPEN_DIRECTORY]: Implement it. (_gl_register_fd): No need to check stat if open already filters all directories.
