* assure: new modulePaul Eggert2014-12-201-3/+3
| | | | | | | | | | | | | | | This works better than 'assert' when compiling with -DNDEBUG, as it avoids some compiler diagnostics in that case. Reported by Norihiro Tanaka in: http://lists.gnu.org/archive/html/bug-gnulib/2014-12/msg00215.html * MODULES.html.sh (func_all_modules): Add 'assure'. * lib/assure.h, modules/assure: New files. * lib/chdir-long.c, lib/cycle-check.c, lib/fchdir.c, lib/fts.c: * lib/poll.c, lib/savewd.c, lib/utimens.c, lib/xstrtol.c: Prefer 'assure' to 'assert'. * modules/chdir-long, modules/cycle-check, modules/fchdir: * modules/poll, modules/savewd, modules/utimens, modules/xstrtol: Depend on 'assure'.

* fchdir: avoid extra chdir and fix testEric Blake2011-04-271-35/+19
| | | | | | | | | | | | | | | | | | On Linux, with a forced ac_cv_func_fchdir=no, the test failed because dup2 was not replaced, all because the shell variable ac_cv_func_dup2 had not been set yet. Meanwhile, computing the canonical pathname of a directory on mingw was rather expensive -- multiple chdir()! -- but nothing cared whether the name was canonical, just that it was absolute. * modules/fchdir (Depends-on): Add dosname, filenamecat-lgpl, getcwd-lgpl. * lib/fchdir.c (get_name): Any absolute name will do; it does not have to be canonical. * m4/dup2.m4 (gl_REPLACE_DUP2): Ensure dup2 is replaced.

* fcntl: use to simplify other modulesEric Blake2009-12-161-4/+1
| | | | | | | | | | | | | | | | | | | | | 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.

* fchdir: avoid memory leak on re-registration.Eric Blake2009-12-081-3/+6
| | | | | | | | | 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>
* fchdir: fix logic bugsEric Blake2009-12-081-4/+3
| | | | | | | | | | | | | 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.

* fchdir: avoid infinite recursion in mingwEric Blake2009-10-141-0/+1
| | | | | | | | | 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>

* rename, fchdir: don't ignore chdir failureEric Blake2009-10-021-1/+2
| | | | | | | | | | | | | | | | | 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>
* fchdir: another mingw fixEric Blake2009-09-231-1/+41
| | | | | | | | | | | | | | | | 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>
