Paul Eggert 229b2a01 2006-11-20T22:01:30 * lib/openat.h (rpl_fstatat): New macro, if [HAVE_OPENAT && ! LSTAT_FOLLOWS_SLASHED_SYMLINK. (fstatat): Define to rpl_fstatat under the same conditions, unless COMPILING_FSTATAT. * m4/openat.m4 (gl_FUNC_OPENAT): Compile fstatat.c too, if fstatat seems to have the bug. * lib/fstatat.c: New file. * modules/openat (Files): Add it.
Paul Eggert 8b3f78cd 2006-08-17T20:34:21 Update from coreutils. * lib/__fpending.h: Add copyright notice. * lib/fprintftime.h: Likewise. * lib/savedir.c: Use (C) in copyright notice. * lib/savedir.h: Likewise. 2006-08-15 Jim Meyering <jim@meyering.net> * lib/at-func.c: New file, with the logic of all emulated at-functions. * lib/openat-priv.h: Include <errno.h> and define ENOSYS, in support of the EXPECTED_ERRNO macro. * lib/openat.c (fstatat, unlinkat, fchownat): Remove function definitions. Instead, define the appropriate symbols and include "at-func.c". * lib/mkdirat.c (mkdirat): Likewise. * lib/fchmodat.c (fchmodat): Likewise. (ENOSYS): Remove definition. * lib/openat.c: Don't include <errno.h>, now that "openat-priv.h" does it. Don't include "unistd--.h" -- it wasn't ever used. 2006-01-17 Jim Meyering <jim@meyering.net> Rewrite fts.c not to change the current working directory, by using openat, fstatat, fdopendir, etc.. * lib/fts.c [! _LIBC]: Include "openat.h" and "unistd--.h". (HAVE_OPENAT_SUPPORT): Define. [_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. [struct FTS] (fts_rft): Remove now-unused member. [struct FTS] (fts_cycle.state): Improve comment. * lib/openat.c (openat_needs_fchdir): New function. * lib/openat.h (openat_needs_fchdir): Declare it. 2006-08-15 Jim Meyering <jim@meyering.net> * m4/openat.m4 (gl_FUNC_OPENAT): Add at-func.c via AC_LIBSOURCES. 2006-01-17 Jim Meyering <jim@meyering.net> * m4/fts.m4 (gl_FUNC_FTS_CORE): Depend on gl_FUNC_OPENAT. 2006-01-11 Jim Meyering <jim@meyering.net> * m4/openat.m4 (gl_FUNC_OPENAT): Require and compile fchmodat.c. Check for the lchmod function.
Paul Eggert 7e69cc2d 2006-02-21T06:40:34 * getcwd.c (AT_FDCWD): Work around a bug in Solaris 9 and 10, where AT_FDCWD exceeds INT_MAX. * openat.h (AT_FDCWD): Likewise.
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.

(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 9db27e41 2005-10-02T22:38:45 Sync from coreutils. * lib/.cppi-disable: Add getaddrinfo.h, getdelim.h, getline.h, getpass.c mbchar.h, mbuiter.h, strcase.h, strnlen.h, strnlen1.h. * lib/.cvsignore: Add fts.h, search.h, t-fpending. * lib/settime.c (settime): Fix { typo in previous patch. Also, don't bother returning ENOSYS if settimeofday or stime fails; just let them return whatever errno they want to return. * lib/utimens.c: Include unistd.h, for dup2. (futimens): Fix typo: HAVE_FUTIMESAT was misspelled in an #if. (futimens) [! HAVE_FUTIMESAT]: If !file, set errno before returning -1. * lib/fts-cycle.c [HAVE_CONFIG_H]: Include <config.h>. * lib/openat-die.c: Use `#ifdef HAVE_CONFIG_H', not `#if HAVE_CONFIG_H'. * lib/openat.c (fdopendir): Do not define if HAVE_FDOPENDIR. Remove AT_FDCWD test. Do not consume the fd unless successful. * lib/openat.h (fdopendir): Do not define if HAVE_FDOPENDIR. * lib/settime.c (settime): Move the HAVE_STIME block `up' into an #elif block, so that we don't even try to compile it if settimeofday is available. This works around a compilation failure on OSF1 V5.1, due to stime requiring a `long int*' while tv_sec is `int'. * m4/openat.m4 (gl_FUNC_OPENAT): Check for fdopendir. * m4/ullong_max.m4 (gl_ULLONG_MAX): Simplify so that it merely defines ULONG_MAX_LT_ULLONG_MAX. Thomas M.Ott reports that ULLONG_MAX doesn't work with 2.7.2.1. * m4/utimes.m4 (gl_FUNC_UTIMES): Detect the version of utimes from glibc-2.2.5 that fails for read-only files. * m4/chdir-long.m4 (gl_FUNC_CHDIR_LONG): Compare $gl_have_path... against `yes', rather than just testing for nonempty.
Paul Eggert 357e1c26 2005-09-22T23:30:37 * modules/openat (Files): Add lib/openat-die.c. (Depends-on): Remove error, exitfail. Add dirname. * lib/openat.c (fdopendir): Be sure to close the supplied file descriptor before returning. This makes our replacement implementation a little closer to Solaris's, where fdopendir ties the file descriptor to the returned DIR* pointer. * lib/openat.c (unlinkat): New function. * lib/openat.h (unlinkat): Add prototype. * lib/openat-die.c (openat_save_fail): Rename from openat_save_die. (openat_restore_fail): Rename from openat_restore_die. * lib/openat.c, openat.h: Reflect s/_die/_fail/ renaming. Provide an alternative to exiting immediately upon save_cwd or restore_cwd failure. Now, an application can arrange e.g., to perform a longjump in that case. * lib/openat.c: Include dirname.h. Use IS_ABSOLUTE_FILE_NAME rather than testing for leading slash. (rpl_openat, fdopendir, fstatat): Call openat_save_die and openat_restore_die rather than calling error directly. Don't include "error.h" or "exitfail.h"; they're no longer needed. * lib/openat-die.c (openat_save_die, openat_restore_die): New file. * lib/openat.h (openat_save_die, openat_restore_die): Declare and define. * m4/openat.m4 (gl_FUNC_OPENAT): Add openat-die.c.
Jim Meyering d1eb42bd 2005-07-02T09:45:07 Assume HAVE_FCNTL_H (i.e., include <fcntl.h> unconditionally, and don't include <sys/file.h>).
Paul Eggert 359c0a71 2005-06-02T20:41:04 Sync from coreutils.

Paul Eggert 267a39ba 2005-05-14T06:03:57 *** empty log message ***
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. Add AC_LIBOBJ for save-cwd.
