Paul Eggert 0632e115 2006-09-13T22:38:14 * _fpending.c: Include <config.h> unconditionally, since we no longer worry about uses that don't define HAVE_CONFIG_H. * acl.c, alloca.c, argmatch.c, atexit.c, backupfile.c: * basename.c, c-stack.c, c-strtod.c, calloc.c, canon-host.c: * canonicalize.c, chdir-long.c, chdir-safer.c, chown.c: * cloexec.c, close-stream.c, closeout.c, creat-safer.c: * cycle-check.c, diacrit.c, dirchownmod.c, dirfd.c, dirname.c: * dup-safer.c, dup2.c, error.c, euidaccess.c, exclude.c: * exitfail.c, fchmodat.c, fchown-stub.c, fd-safer.c: * file-type.c, fileblocks.c, filemode.c, filenamecat.c: * fnmatch.c, fopen-safer.c, fprintftime.c, free.c, fsusage.c: * ftruncate.c, fts-cycle.c, fts.c, full-write.c, gai_strerror.c: * getcwd.c, getdate.y, getdomainname.c, getgroups.c: * gethostname.c, gethrxtime.c, getloadavg.c, getlogin_r.c: * getndelim2.c, getnline.c, getopt.c, getopt1.c, getpass.c: * gettime.c, gettimeofday.c, getugroups.c, getusershell.c: * glob.c, group-member.c, hard-locale.c, hash-pjw.c, hash.c: * human.c, idcache.c, inet_ntop.c, inet_pton.c, inttostr.c: * isdir.c, lchown.c, linebuffer.c, long-options.c, lstat.c: * malloc.c, md5.c, memcasecmp.c, memchr.c, memcmp.c, memcoll.c: * memcpy.c, memmove.c, memrchr.c, mkancesdirs.c, mkdir-p.c: * mkdir.c, mkdirat.c, mkstemp-safer.c, mkstemp.c, modechange.c: * mountlist.c, nanosleep.c, obstack.c, open-safer.c: * openat-die.c, openat.c, pagealign_alloc.c, physmem.c: * pipe-safer.c, posixtm.c, posixver.c, putenv.c, quote.c: * quotearg.c, raise.c, readtokens.c, readtokens0.c, readutmp.c: * realloc.c, regex.c, rename.c, rmdir.c, rpmatch.c, safe-read.c: * same.c, save-cwd.c, savedir.c, setenv.c, settime.c, sha1.c: * sig2str.c, snprintf.c, strdup.c, strerror.c, strftime.c: * stripslash.c, strndup.c, strnlen.c, strpbrk.c, strtod.c: * strtoimax.c, strtol.c, strverscmp.c, tempname.c, time_r.c: * timegm.c, tmpfile-safer.c, unlinkdir.c, userspec.c, utime.c: * utimecmp.c, utimens.c, version-etc-fsf.c, version-etc.c: * xalloc-die.c, xgetcwd.c, xgethostname.c, xmalloc.c: * xmemcoll.c, xnanosleep.c, xreadlink.c, xstrtod.c: * xstrtoimax.c, xstrtol.c, xstrtoumax.c, yesno.c: Likewise.
Paul Eggert efc96869 2006-08-31T21:54:54 * lib/chdir-long.c: Include <fcntl.h>, for O_DIRECTORY. Don't include unistd.h or limits.h; not needed, since chdir-long.h does that for us. (O_DIRECTORY): Remove. * modules/chdir-long (Depends-on): Add fcntl.
Paul Eggert 14bf04a5 2006-01-09T23:13:56 Sync from coreutils. * doc/getdate.texi (General date syntax): Invalid dates are rejected. (Time of day items): Mention the possibility of leap seconds. Problem reported by Dr. David Alan Gilbert. * lib/chdir-long.c (cdb_free): Don't bother trying to open directory for write access: POSIX says that must fail. * lib/fts.c (diropen): Likewise. * lib/save-cwd.c (save_cwd): Likewise. * lib/chdir-long.c (cdb_free): Open with O_NOCTTY | O_NONBLOCK as well, for minor improvements on hosts that lack O_DIRECTORY. * lib/gettime.c (gettime) [!defined OK_TO_USE_1S_CLOCK]: Report an error at compile-time if only a 1-second nominal clock resolution is found. * lib/lchmod.h: New file. * lib/mkdir-p.c: Include lchmod.h, lchown.h. (make_dir_parents): Use lchown rather than chown, and lchmod rather than chmod. * lib/mountlist.c (ME_DUMMY): "none" and "proc" file systems are dummies too. Problem with "none" reported by Bob Proulx. Problem with "proc" reported by n0dalus. * lib/mountlist.c: Include <limits.h>. (dev_from_mount_options) [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: New function. It no longer assumes "dev=" has the System V meaning on Linux (since it doesn't). It also parses "dev=" more carefully. (read_file_system_list) [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: Use it. MOUNTED_GETMNTENT2 is new here; the code didn't used to look for dev= in that case. * lib/posixtm.h (PDS_PRE_2000): New macro. * lib/posixtm.c (year): Arg is now syntax_bits rather than allow_century. All usages changed. Reject dates outside the range 1969-1999 if PDS_PRE_2000 is used. * modules/mkdir-p (Files): Add chdir-safer.c, chdir-safer.h, lchmod.h, chdir-safer.m4, lchmod.m4. * modules/openat: Add mkdirat.c, openat-priv.h. * modules/lib-ignore: New file. * lib/version-etc.c (COPYRIGHT_YEAR): Update to 2006. Rewrite fts.c not to change the current working directory, by using openat, fstatat, fdopendir, etc.. * lib/fts.c [! _LIBC]: Include "openat.h", "unistd--.h", and "fcntl--.h". [_LIBC] (fchdir): Don't undef or define; no longer used. (FCHDIR): Define in terms of cwd_advance_fd rather than fchdir. Now, this `function' always succeeds, and consumes its file descriptor parameter -- so callers must not close such FDs. Update callers. (diropen_fd, opendirat, cwd_advance_fd): New functions. (diropen): Add parameter, SP. Adjust all callers. Implement using diropen_fd, rather than open. (fts_open): Initialize new member, fts_cwd_fd. Remove fts_rft-setting code. (fts_close): Close fts_cwd_fd, if necessary. (__opendir2): Define in terms of opendir or opendirat, depending on whether the FST_NOCHDIR flag is set. (fts_build): Since fts_safe_changedir consumes its FD, and since this code must do `closedir(dirp)', dup the dirfd(dirp) argument, and close the dup'd file descriptor upon failure. (fts_stat): Use fstatat(...AT_SYMLINK_NOFOLLOW) in place of lstat. (fts_safe_changedir): Tweak semantics to reflect that this function now calls cwd_advance_fd and hence consumes its FD argument. * lib/fts_.h [struct FTS] (fts_cwd_fd): New member. (fts_rft): Remove now-unused member. * lib/openat.c (fchownat): New function. * lib/openat.h (fchmodat, fchownat): Declare. (chmodat, lchmodat): Define convenience functions. (chownat, lchownat): Likewise. * lib/chdir-safer.h, chdir-safer.c: New files. * lib/modechange.c (mode_compile): Reject an invalid mode string that starts with an octal digit. From Andreas Gruenbacher. * lib/openat.c: Include "fcntl--.h" and "unistd--.h", to map open and dup to open_safer and dup_safer, respectively. (openat_permissive): Fix typo in comment. * lib/openat.c: Don't include <stdlib.h>, <unistd.h>, <fcntl.h>, "gettext.h"; either no longer needed or are guaranteed by openat.h. (_): Remove; no longer needed. (openat): Renamed from rpl_openat; no need for rpl_openat since openat.h renames openat for us. Replace most of the body with a call to openat_permissive, to avoid duplicate code. Port to (probably hypothetical) environments were mode_t is wider than int. (openat_permissive): Require mode arg, so that we can check types better. Put it just after flags. Change cwd failure indicator from pointer-to-bool to pointer-to-errno-value. All callers changed. Invoke openat_save_fail and/or openat_restore_fail if cwd_errno is null, so that openat can call us. (openat_permissive, fdopendir, fstatat, unlinkat): Simplify errno handling to avoid some duplicate code, as it's OK to set errno on success. * lib/openat.h: Revamp code so that function macros depend on __OPENAT_PREFIX only, not also on AT_FDCWD. (openat_ro): Remove. Caller changed to use openat_permissive. (openat_permissive): Now a macro, if not a function. (openat_restore_fail, openat_save_fail): Now always functions, since mkdirat needs them even if __OPENAT_PREFIX is defined. * lib/openat-priv.h: New file, defining macros used by mkdirat.c and openat.c. * lib/mkdirat.c: Include openat-priv.h. Remove definitions of macros defined therein. * lib/openat.c: Likewise. * lib/mkdirat.c (mkdirat): New file and function. * lib/openat.h (mkdirat): Declare. * lib/openat.c (fdopendir): Don't change errno when returning non-NULL. * lib/openat.h (openat_permissive): Declare. (openat_ro): Define. * lib/openat.c (EXPECTED_ERRNO): New macro. (openat_permissive): New function -- used in remove.c rewrite. (all functions): Set errno just before returning, only if there was an actual failure. Use EXPECTED_ERRNO rather than comparing against only ENOTDIR. Emulate openat-family functions using Linux's procfs, if possible. Idea and some code based on Ulrich Drepper's glibc changes. * lib/openat.c: (BUILD_PROC_NAME): New macro. Include <stdio.h>, <string.h>, "alloca.h" and "intprops.h". (rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s, before falling back on save_cwd and restore_cwd. (fdopendir, fstatat, unlinkat): Likewise. * lib/openat.c (fstatat, unlinkat): Perform the syscall directly, skipping the save_cwd...restore_cwd overhead, if FILE is absolute. * lib/openat.c (rpl_openat): Use the promoted type (int), not mode_t, as second argument to va_arg. Otherwise, some versions of gcc warn that `if this code is reached, the program will abort'. Add POSIX ACL support * lib/acl.h (copy_acl, set_acl): Add declarations. * lib/acl.c (acl_entries): Add fallback implementation for POSIX ACL systems other than Linux. (chmod_or_fchmod): New function: use fchmod when possible, and chmod otherwise. (file_has_acl): Add a POSIX ACL implementation, with a Linux-specific subcase. (copy_acl): Add: copy an acl and S_ISUID, S_ISGID, and S_ISVTX from one file to another. Fall back to fchmod/chmod when acls are unsupported. (set_acl): Add: set a file's acl and S_ISUID, S_ISGID, and S_ISVTX to a defined value. Fall back to fchmod/chmod when acls are unsupported. * m4/lib-ignore.m4: New file. * m4/lchmod.m4: New file. * m4/chdir-safer.m4: New file. * m4/openat.m4 (gl_FUNC_OPENAT): Require and compile mkdirat.c. Require openat-priv.h. * m4/acl.m4 (AC_FUNC_ACL): Add POSIX ACL and Linux-specific acl tests.

Paul Eggert 8b03458e 2005-05-02T07:00:50 Merge from coreutils.
Paul Eggert 01803982 2005-02-03T20:38:14 * modules/chdir-long (Depends-on): Add memrchr. * modules/memrchr (Files): Add lib/memrchr.h. (Include): "memrchr.h". * lib/memrchr.h: New file. * lib/chdir-long.c: Include it. * lib/memrchr.c [!defined _LIBC]: Include it rather than <string.h> Don't bother including stddef.h. * m4/memrchr.m4 (gl_FUNC_MEMRCHR): Add AC_LIBSOURCES, for memrchr.h.
Paul Eggert 6528cac5 2005-01-22T05:37:06 * modules/chdir-long (Depends-on): Remove mempcpy. * lib/openat.h (AT_SYMLINK_NOFOLLOW): Define to 4096, so it's the same value as for Solaris 9. * lib/chdir-long.c (chdir_long): Rewrite to remove limitation on component length. This included changing the parameter to be of type `char *' rather than `char const *'. * lib/chdir-long.h (chdir_long): Update prototype. * lib/openat.c (fdopendir, fstatat): New functions. * lib/openat.h: Include headers required for use of DIR and struct stat. [AT_SYMLINK_NOFOLLOW]: Define. (fdopendir, fstatat): Add prototypes.
Paul Eggert d9203c96 2005-01-18T21:58:11 * modules/chdir-long, modules/openat: New files. * modules/save-cwd (Depends-on): Depend on chdir-long. (Makefile.am): Remove lib_SOURCES; now handled by AC_LIBSOURCES. * lib/save-cwd.c: Include "save-cwd.h" before other include files. (O_DIRECTORY): Remove; not needed here, since "." must be a directory. All uses removed. (save_cwd): Use __sgi || __sun, not sun || __sun. __sun is universal on Suns, and we also need to test for IRIX. Revamp code to use 'if' rather than '#if'. Avoid unnecessary comparison of cwd->desc to 0. Change the name of the robust chdir function from chdir to chdir_long. * lib/save-cwd.c: Include chdir-long.h rather than chdir.h. (restore_cwd): Use chdir_long, not chdir. * lib/chdir-long.c: Renamed from chdir.c. * lib/chdir-long.h: Renamed from chdir.h. [!defined PATH_MAX]: Define chdir_long to chdir on systems like the Hurd. * m4/chdir-long.m4, openat.m4: New files. * m4/save-cwd.m4 (gl_SAVE_CWD): Add AC_LIBSOURCES for save-cwd.c, save-cwd.h.
