* maint: update all copyright year number rangesEric Blake2013-01-011-1/+1
| | | | | | Run "make update-copyright". Compare to commit 1602f0a from last year. Signed-off-by: Eric Blake <eblake@redhat.com>
* maint: update all copyright year number rangesJim Meyering2012-01-011-1/+1
| | | | Run "make update-copyright".
* openat: Increase OPENAT_BUFFER_SIZE from 512 to at least 1024Paul Eggert2011-01-111-1/+21
| | | | | | | | | | This avoids heap allocation for file names whose lengths are in the range 512..1023, with the upper bound increasing to at most 4031 depending on the platform's PATH_MAX. (We do not want pathmax.h here as it might supply a non-constant PATH_MAX.) * lib/openat-priv.h (SAFER_ALLOCA_MAX, SAFER_ALLOCA): New macros. Perhaps they should be moved to malloca.h? (OPENAT_BUFFER_SIZE): Use them.
* maint: update almost all copyright ranges to include 2011Jim Meyering2011-01-011-1/+1
| | | | Run the new "make update-copyright" rule.
* update nearly all FSF copyright year lists to include 2010Jim Meyering2010-01-011-1/+1
| | | | | Use the same procedure as for 2009, outlined in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/20081
* update nearly all FSF copyright year lists to include 2009Jim Meyering2009-12-291-1/+1
| | | | | | | | | | | | | | | | | | The files named by the following are exempted: grep -v '^#' config/srclist.txt|grep -v '^$' \ | while read src dst; do test -f "$dst" && { echo "$dst"; continue; } test -d "$dst" || continue echo "$dst"/$(basename "$src") done > exempt git ls-files tests/unictype >> exempt In the remaining files, convert to all-interval notation if - there is already at least one year interval like 2000-2003 - the file is maintained by me - the file is in lib/uni*/, where that style already prevails Otherwise, use update-copyright's default.

| | | | Needed for mingw.
* [lib/ChangeLog]Paul Eggert2006-09-301-25/+7
| | | | | | | | | | | | | | | | | | | | | | Work around bug in Solaris 10 /proc file system: /proc/self/fd/NNN/.. isn't the parent directory of the directory whose file descriptor is NNN. This needs to be worked around at run time, not compile time, since a program might be built on Solaris 8, where things work, and run on Solaris 10. * openat-priv.h (BUILD_PROC_NAME): Remove. All callers changed to use the following interface instead: (OPENAT_BUFFER_SIZE): New macro. (openat_proc_name): New function. * at-func.c (AT_FUNC_NAME): Adjust to above changes. * openat.c (openat_permissive, openat_needs_fchdir, fdopendir): Likewise. * openat-proc.c: New file. [ChangeLog] * modules/openat (Files): Add lib/openat-proc.c. (Depends-on): Add same-inode, stdbool. [m4/ChangeLog] * openat.m4 (gl_FUNC_OPENAT): Add AC_LIBOBJ(openat-proc).

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.
* Sync from coreutils.Paul Eggert2006-01-091-0/+52
* 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.
