+
+ Remove iotty test
+ The auxiliary utility ttyemu proved to be unreliable.
+ Given existing
+ differences between pty implementations and termios ioctls
+ on various
+ platforms, writing it in a portable way requires effort
+ disproportional
+ to its actual purpose.
+ * configure.ac: Remove check for grantpt
+ * gnulib.modules: Remove posix_openpt, ptsname, and unlockpt
+ * tests/Makefile.am (TESTSUITE_AT): Remove iotty.at

+
+ xattrs: fix build on Darwin
+ Be careful to define HAVE_XATTRS when not all needed xattr-related
+ functions are properly defined either in libc or libattr.
+ Reported independently by Denis Excoffier and Dominyk Tille.
+ * acinclude.m4 (TAR_HEADERS_ATTR_XATTR_H): Check for each xattr
+ function separately. Don't AC_CHECK_LIB (LIBS is filled by
+ AC_SEARCH_LIBS when necessary).
+ * src/Makefile.am: The LDADD -lattr was redundant.

+
+ New option --clamp-mtime
+ The new `--clamp-mtime` option will change the behavior of
+ `--mtime` to only
+ use the time specified if the file mtime is newer than the
+ given time.
+ The `--clamp-mtime` option can only be used together with
+ `--mtime`.
+ Typical use case is to make builds reproducible: to loose less
+ information, it's better to keep the original date of an archive,
+ except for
+ files modified during the build process. In that case, using
+ a reference
+ (and thus reproducible) timestamps for the latter is good
+ enough. See
+ <https://wiki.debian.org/ReproducibleBuilds> for more information.
+ Patch submitted by Jeremy Bobbio and
+ Daniel Kahn Gillmor <dkg@fifthhorseman.net>

+
+ Minor fix
+
+ Fix handling of filename-selection options.
+ Filename-selection options are --wildcards, --recursive, etc. (see
+ names.c for a complete list). These options are
+ position-sensitive,
+ i.e. each such option affects all filenames and filename-selection
+ options that appear after it until eventually cancelled by a
+ corresponding counterpart option.
+ These options can appear in "file-from" file lists, which
+ means that
+ they cannot be handled right away, but instead should be put on
+ the "name_elt" list and processed sequentionally, as file name
+ arguments
+ are.
+ * src/common.h (warn_regex_usage): Remove.
+ (name_add_name): Change signature.
+ (name_add_dir, name_add_file): Remove prototypes.

+ tar: fix symlink race and symlink transform bug
+ Problem reported by Tobias Stoeckmann in:

+ * gnulib.modules: Add areadlinkat-with-size.
+ * src/create.c: Include areadlink.h.
+ (dump_file0): Use areadlinkat_with_size, rather than trying to do

+ link name, not the original link name, when deciding whether the
+ name is long enough to require writing a long link.

+ tar: port -d to longer symlinks
+ * src/compare.c (diff_symlink):

+ Prefer memcmp to strncmp where either will do.
+

+ * gnulib.modules: Remove 'acl' and add 'file-has-acl'.
+
+ tar: pacify GCC 5.1 -Wformat-signedness
+ * lib/wordsplit.c (struct wordsplit_node.flags):

+
+ Reduce memory consumption when handling the -T option.
+ The commit cdb27293 made the -T option more flexible, but
+ incurred a very considerable memory overhead by storing
+ all file names in the argument array. In case of very
+ big file lists this caused tar to run out of memory. This
+ was reported by Christian Wetzel <wetzel@phoenix-pacs.de>
+ on March 14, 2013
+ (http://lists.gnu.org/archive/html/bug-tar/2013-03/msg00018.html).
+ On the other hand, Michal Žeidl discovered that tar malfunctioned
+ when given empty file lists or lists with the trailing newline
+ missing in the last entry. This was reported by Pavel Raiskup
+ on July 23
+ (http://lists.gnu.org/archive/html/bug-tar/2013-07/msg00009.html

+ and the uid/gid could in theory be out of range. Leave major and

+ (xheader_read): Last arg is off_t, not size_t.
+ Caller should diagnose negative arg, as needed.
+ Check that it's in range.

+
+ tar: use birthtime rather than ctime when checking identity
+ Without this fix, tar would sometimes mishandle the extraction of

+
+ Run alternative decompression programs if the principal one is
+ not available.
+ Some compression programs are able to handle various compression
+ formats
+ (e.g. `gzip' can decompress files created by `compress', `xz'
+ is able
+ to handle lzma, etc.) Tar tries to use such programs for
+ decompression
+ if the principal decompressor cannot be started.
+ * src/buffer.c (compress_type): Swap ct_none and ct_tar.

+ (WARN_DECOMPRESS_PROGRAM): New flag.
+ (WARN_VERBOSE_WARNINGS): Include WARN_DECOMPRESS_PROGRAM.
+ * src/warning.c (warning_args): Add "decompress-program".
+ (warning_types): Add WARN_DECOMPRESS_PROGRAM.
+ * src/system.c (run_decompress_program): New function.
+ (sys_child_open_for_uncompress): Use run_decompress_program
+ instead of calling execlp directly.
+
+2010-11-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ tests: fix some issues with signals, timestamps, "test" typo
+ * tests/extrac17.at: Add --warning=no-timestamp, to avoid

+ * tests/remfiles01.at: Discard diagnostics that some shells
+ generate about broken pipes.
+ * tests/sigpipe.at: Likewise.
+ * tests/remfiles01.at: Fix typo: "test $EC" was written where
+ "test $EC -ne 0" was intended.
+
+2010-11-01 Sergey Poznyakoff <gray@gnu.org.ua>
+
+ Fix extraction of device nodes.
+ * src/extract.c (extract_node): Do not mask out node type.
+ The bug was introduced in commit ea964cce.
+
+2010-10-28 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: don't cross struct member boundaries with OLDGNU_MAGIC
+ * src/create.c (write_gnu_long_link, start_header): Access
+ header->buffer + offsetof (struct posix_header, magic), instead of
+ header->header.magic, when reading or writing the OLDGNU_MAGIC
+ pattern. The code violates the C standard without this change,
+ and GCC warns about this if fortify checking is enabled. It's not
+ a bug on traditional (i.e., non-debugging) platforms, but it does
+ violate the C standard so it should be fixed. Problem originally
+ reported by John Emil Karlson in
+ <http://lists.gnu.org/archive/html/bug-tar/2010-04/msg00023.html>.
+ * src/list.c (decode_header): Likewise.
+
+ tests: port to sh variants that squirrel away file descriptors
+ OpenBSD /bin/sh, and some other sh variants, squirrel away file
+ descriptors before closing them. For example, for "cat 3<&-" they
+ first dup file descriptor 3 to a fd that is 10 or greater, then
+ close 3 (because if "cat" had been a builtin command like ":" then
+ they would have wanted to avoid the fork and restore the fd after
+ ":" finished); and they treat ordinary (forking) commands the same
+ as builtin commands. This approach fails after "ulimit -n 10".
+ Work around this deficiency by closing the file descriptors before
+ invoking ulimit. Problem reported by Christian Weisgerber in
+ <http://lists.gnu.org/archive/html/bug-tar/2010-10/msg00041.html>;
+ solution suggested by Jilles Tjoelker in
+ <http://article.gmane.org/gmane.comp.shells.dash/415>.
+ * tests/extrac11.at (scarce file descriptors): Close file
+ descriptors before invoking ulimit -n.
+
+2010-10-27 Sergey Poznyakoff <gray@gnu.org.ua>
+
+ Transform file names when updating and appending to archives.

+
+2010-10-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ tests: port to Solaris diff
+ * tests/extrac13.at: Don't assume that "diff -c" outputs nothing
+ when there are no differences. This is not true on Solaris,
+ where it outputs "No differences encountered".
+
+ tar: fix -x --overwrite bug (no --dereference, ! O_NOFOLLOW)
+ This bug was discovered on Solaris 8. On older hosts lacking
+ O_NOFOLLOW, tar -x --overwrite (without --dereference) follows
+ symbolic links, causing the "extract over symlinks" test to fail.
+ * src/extract.c (open_output_file): If O_NOFOLLOW is needed but
+ does not work, check for a symlink separately.
+
+ tar: don't use "((" in shell scripts
+ * tests/extrac11.at: Replace "((" with "( (" in shell scripts, as
+ "((" is not portable to the Korn shell, and POSIX 1003.1-2008 says
+ that "((" is not portable.
+
+2010-10-26 Sergey Poznyakoff <gray@gnu.org.ua>
+
+ Make sure name matching occurs before name transformation.
+ The commit 9c194c99 altered that order.
+ * src/list.c (transform_stat_info): New function. Split off from
+ decode_header.
+ (read_and): Call transform_stat_info right before do_something,
+ and after deciding if we should proceed with this member name,
+ so that name matching occurs before name transformation.
+ * tests/extrac17.at: New file.
+ * tests/Makefile.am (TESTSUITE_AT): Add extrac17.at
+ * tests/testsuite.at: Include extrac17.at.
+

+
+ tar: use more-accurate diagnostic when intermediate mkdir fails
+ Without this change, if tar tried to extract a file A/B/C, noticed
+ that A/B didn't exist, attempted to mkdir A/B, and the mkdir
+ failed, it did not diagnose the mkdir failure, but simply reported
+ the failure to open A/B/C. This sometimes led to confusion
+ because it wasn't clear what tar was trying to do, in particular
+ that tar tried to mkdir A/B. With this patch, tar issues two
+ diagnostics in this case: one for A/B and the other for A/B/C.
+ Problem reported by Hauke Laging in
+ <http://lists.gnu.org/archive/html/bug-tar/2010-10/msg00020.html>.
+ * gnulib.modules: Remove faccessat.
+ * src/extract.c (make_directories): New arg INTERDIR_MADE.
+ Diagnose mkdir failure. Return 0 on success, nonzero on failure,
+ as opposed to nonzero iff some directory was created. All callers
+ changed. Simplify the code when mkdir fails, by checking whether
+ the desired file exists unless errno==EEXIST: this is more robust.
+ * tests/extrac15.at: New test, to check this.
+ * tests/Makefile.am (TESTSUITE_AT): Add it.
+ * tests/testsuite.at: Include it.
+
+ tests: port to NFS file servers with clock skew
+ Several of the tests assumed that a newly created file cannot
+ have a time stamp dated in the future. This assumption is not
+ true when files are served by a remote host whose clock is
+ slightly in advance of ours. Fix the problems that I observed
+ when running "make check" a couple of times on such a server.
+ * tests/backup01.at: Use --warning=no-timestamp to suppress
+ clock-skew warnings.

+
+2010-09-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: -x -C symlink fix
+ * src/misc.c (chdir_do): Don't use O_NOFOLLOW when opening the

+ matches the new documentation.
+ * tests/extrac14.at: New file.
+ * tests/Makefile.am (TESTSUITE_AT): Add it.
+ * tests/testsuite.at: Include it.
+
+ tar: --dereference consistency
+ This closes another race condition, that occurs when overwriting a
+ symlink with a regular file.
+ * NEWS (--dereference consistency): New section.
+ * doc/tar.texi (Option Summary): Describe new --deference
+ behavior.
+ (dereference): Likewise. Remove discussion that I didn't follow,
+ even before --dereference was changed.
+ * src/common.h (deref_stat, set_file_atime): Adjust signatures.
+ * src/compare.c (diff_file, diff_multivol): Respect
+ open_read_flags
+ instead of rolling our own flags. This implements the new
+ behavior
+ for --dereference.
+ (diff_file, diff_dumpdir): Likewise, for fstatat_flags.
+ * src/create.c: Adjust to set_file_atime signature change.
+ * src/extract.c (mark_after_links, file_newer_p, extract_dir):
+ Likewise.
+ * src/incremen.c (try_purge_directory): Likewise.
+ * src/misc.c (maybe_backup_file): Likewise.
+ * src/extract.c (file_newer_p): New arg STP. All callers changed.
+ (maybe_recoverable): New arg REGULAR. All callers changed.
+ Handle the case of overwriting a symlink with a regular file,
+ when --overwrite is specified but --dereference is not.
+ (open_output_file): Add O_CLOEXEC, O_NOCTTY, O_NONBLOCK for
+ consistency with file creation. Add O_NOFOLLOW if
+ overwriting_old_files && ! dereference_option.
+ * src/incremen.c (update_parent_directory): Use fstat, not
+ fstatat;
+ there's less to go wrong.
+ * src/misc.c (deref_stat): Remove DEREF arg. All callers changed.
+ Instead, use fstatat_flags.
+ (set_file_atime): Remove ATFLAG arg. All callers changed.
+ Instead, use fstatat_flags.
+ * src/names.c, src/update.c: Adjust to deref_stat signature
+ change.
+ * src/tar.c (get_date_or_file): Use stat, not deref_stat, as this
+ is not a file to be archived.
+ * tests/Makefile.am (TESTSUITE_AT): Add extrac13.at.
+ * tests/extrac13.at: New file.
+ * tests/testsuite.at: Include it.

+ I don't understand this code either, but Sergey can take a look at
+ this patch, and perhaps install a better one, when he has

+ * src/incremen.c (append_incremental_renames): Don't actually
+ append
+ anything to DIR if DIR is null.
+
+2010-09-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: prefer openat-style functions
+ This change replaces traditional functions like 'open' with the
+ POSIX.1-2008 functions like 'openat'. Mostly this is an internal
+ refactoring change, in preparation for further changes to close
+ some races.
+ * gnulib.modules: Add faccessat, linkat, mkfifoat, renameat,
+ symlinkat.
+ Remove save-cwd.
+ * src/Makefile.am (tar_LDADD): Add $(LIB_EACCESS).
+ * tests/Makefile.am (LDADD): Likewise.
+ * src/common.h (chdir_fd): New extern var.
+ * src/compare.c (diff_file, diff_multivol): Use openat instead
+ of open.
+ * src/create.c (create_archive, restore_parent_fd): Likewise.
+ * src/extract.c (create_placeholder_file): Likewise.
+ * src/names.c (collect_and_sort_names): Likewise.

+ * src/compare.c (diff_file): Use chdir_fd instead of AT_FDCWD.
+ * src/create.c (subfile_open, dump_file0): Likewise.
+ * src/extract.c (fd_chmod, fd_chown, fd_stat, set_stat):
+ (repair_delayed_set_stat, apply_nonancestor_delayed_set_stat):
+ Likewise.
+ * src/extract.c (mark_after_links, file_newer_p, extract_dir):
+ (extract_link, apply_delayed_links):
+ Use fstatat rather than stat or lstat.
+ * src/misc.c (maybe_backup_file, deref_stat): Likewise.
+ * src/extract.c (make_directories): Use mkdirat rather than mkdir.
+ Use faccessat rather than access. This fixes a minor permissions
+ bug when tar is running setuid (who would want to do that?!).
+ (open_output_file): Use openat rather than open.
+ In the process, this removes support for Masscomp's O_CTG files,
+ which aren't compatible with openat's signature. Masscomp! Wow!
+ That's a blast from the past. As far as I know, that operating
+ system hasn't been supported for more than 20 years.
+ (extract_link, apply_delayed_links):
+ Use linkat rather than link.
+ (extract_symlink, apply_delayed_links):
+ Use symlinkat rather than symlink.
+ (extract_node): Use mknodat rather than mknod.
+ (extract_fifo): Use mkfifoat rather than mkfifo.
+ (apply_delayed_links): Use unlinkat rather than unlink or rmdir.
+ * src/misc.c (safer_rmdir, remove_any_file): Likewise.
+ * src/unlink.c (flush_deferred_unlinks): Likewise.
+ * src/extract.c (rename_directory): Use renameat rather than
+ rename.
+ * src/misc.c (maybe_backup_file, undo_last_backup): Likewise.
+ * src/misc.c: Don't include <save-cwd.h>; no longer needed now
+ that we're using openat etc.
+ (struct wd): Add member fd. Remove members err and fd. All uses
+ changed.
+ (CHDIR_CACHE_SIZE): New constant.
+ (wdcache, wdcache_count, chdir_fd): New vars.
+ (chdir_do): Use openat rather than save_cwd. Keep the cache up
+ to date. This code won't scale well, but is good enough for now.
+ * src/update.c (update_archive): Use openat + fdopendir +
+ streamsavedir rather than savedir.
+ This file is a placeholder. It will be replaced with the actual

+
+ tar: add utimens.h includes
+ * src/extract.c: Include <utimens.h>, needed for fdutimens
+ prototype.
+ * src/misc.c: Likewise.
+
+ tar: switch to gnulib fdutimensat module
+ * gnulib.modules: Add fdutimensat.
+ * src/common.h (fd_utimensat): Remove decl.
+ * src/extract.c (set_stat): Call fdutimensat, not fd_utimensat.
+ * src/misc.c (set_file_atime): Likewise.
+ (fd_utimensat): Remove.
+
+2010-09-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: extract permissions for . last
+ * src/common.h (must_be_dot_or_slash): New decl.
+ * src/extract.c (mark_after_links): New function, taking code
+ that used to be in create_placeholder_file.
+ (create_placeholder_file): Use it.
+ (delay_set_stat): Always delay setting status for . and /.
+ * src/misc.c (must_be_dot_or_slash): Now extern.
+ * tests/extrac12.at: New file.
+ * tests/Makefile.am (TESTSUITE_AT): Add it.
+ * tests/testsuite.at: Likewise.
+
+ tar: don't check for getdtablesize; use AC_CHECK_FUNCS_ONCE
+ * configure.ac: Don't check for getdtablesize; no longer needed.
+ Use AC_CHECK_FUNCS_ONCE rather than AC_CHECK_FUNCS, for
+ efficiency.
+
+ tar: extract symlink attributes, close some symlink-related races
+ * NEWS: Describe symlink-extraction improvements.
+ * src/extract.c (enum permstatus): Remove.
+ (fchmod, fchown): Define dummy replacement macros if the system
+ does not supply them.
+ (implemented): New function.
+ (struct delayed_set_stat): Remove members invert_permissions,
+ permstatus. They were too confusing, and tried to do too much
+ in too-little space. Instead, add members current_mode,
+ current_mode_mask, interdir, atflag. All users changed.
+ (struct delayed_link): Add members mode, atime, mtime, to support
+ platforms such as BSD where symlinks have these attributes.
+ All users changed.
+ (fd_chmod): Renamed from fdchmod. New argument atflag. Check for
+ operation not supported at run-time, not at configure-time. Put
+ fd argument first. All callers changed.
+ (fd_chown): Likewise, renaming from fdchown.
+ (fd_stat): Likewise, renaming from fdstat.
+ (set_mode): Remove args stat_info, cur_info, invert_permissions,
+ permstatus. Add args mode, mode_mask, current_mode,
+ current_mode_mask,
+ atflag. All callers changed. Close some races. Use an easier-to
+ understand method for computing permissions. Work around POSIX
+ incompatibility in Linux fchmodat. Support extraction of symlink
+ modes, if the OS allows it.
+ (set_stat): Remove args cur_info, invert_permissions, permstatus.
+ Add args current_mode, current_mode_mask, interdir, atflag.
+ All callers changed. Close some races. Support extraction of
+ attributes on symlinks, if the OS allows it.
+ (delay_set_stat): Remove args invert_permissions, permstatus.
+ Add args current_mode, current_mode_mask, mode, atflag.
+ The ST arg can be null now, indicating that it's an intermediate
+ directory. All callers changed.
+ (repair_delayed_set_stat, apply_nonancestor_delayed_set_stat):
+ Close some races.
+ (extract_dir): Also be paranoid if only --same-permissions, due
+ to semantics of setgid and setuid directories on some hosts.
+ This closes a race on those hosts. Simplify calculation of
+ delay_set_stat arguments; the old code was truly strange and
+ probably wrong in some border cases.
+ (extract_dir, extract_file, extract_node, extract_fifo): Don't
+ rely on
+ unspecified behavior in mode arg of open, mknod, etc. Instead,
+ mask out those bits when creating the file, and add them later via
+ fchmod or chmodat.
+ (open_output_file): file_name is now const. Add arg current_mode,
+ current_mode_mask. All callers changed. When overwriting
+ old files,
+ refuse to overwrite something that is not a regular file, since
+ we're extracting a regular file.
+ (extract_file): Remove the FIXME comment. Whatever the protection
+ issues were, they should be fixed now. As a result of all
+ the other
+ API changes, we now use fchmod etc. rather than chmod etc.,
+ closing
+ some races.
+ (create_placeholder_file, apply_delayed_links): Record desired
+ mode and times for symlinks, for OSes that support that.
+
+2010-09-16 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: tar -x without --incremental no longer sets atime again
+ * src/extract.c (set_stat): Use UTIME_OMIT rather than UTIME_NOW.
+ The UTIME_NOW was there only to emulate the previous behavior of
+ using the current time, and the previous behavior was there only
+ because before we started assuming POSIX.1-2008 there was no
+ portable way to get the effect of UTIME_NOW.
+
+ tar: another --atime-preserve race fix
+ * src/common.h (set_file_atime): Add parentfd arg.
+ * src/compare.c (diff_file): Use it.
+ * src/create.c (dump_file0): Likewise. This closes yet another
+ race condition with symbolic links.
+ * src/misc.c (set_file_atime): Add parentfd arg.
+
+ tar: --atime-preserve fixes for races etc.
+ This patch fixes a race condition in the --atime-preserve=replace
+ option, which might cause tar to improperly follow a symbolic
+ link.
+ It also drops the use of the _FIOSATIME ioctl of Solaris 2.x
+ and later, which loses resolution on time stamps. Modern Solaris
+ systems support full-resolution time stamps in the kernel, and
+ it's not worth the hassle of testing this call, useful only in
+ no-longer-supported Solaris variants.
+ Also, it undoes a change I recently introduced to the --compare
+ option, which caused it to not follow symbolic links unless the
+ --dereference option was also used. Quite possibly this change is
+ a good idea, but the old behavior was documented and the change
+ should not have been installed casually.
+ * configure.ac: Don't check for stropts.h and sys/filio.h.
+ * gnulib.modules: Add futimens, utimensat. Remove futimens.
+ * src/common.h (fd_utimensat): New decl.
+ * src/compare.c (diff_file, diff_multivol):
+ Don't use open_read_flags: those are for --create only.
+ * src/create.c (dump_file0): Adjust to set_file_atime changes.
+ Pass fstatat_flags to set_file_atime, so that symbolic links are
+ not followed inadvertently.
+ * src/extract.c: Don't include utimens.h.
+ (set_stat): Use fd_utimensat ant UTIME_NOW rather than fdutimens.
+ * src/misc.c: Don't include utimens.h, stropts.h, sys/filio.h.
+ (fd_utimensat): New function.
+ (set_file_atime): Use it. New arg atflag, controlling symlink
+ handling. All callers changed.
+
+2010-09-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac: tar: close some race conditions when extracting
+ * configure.ac: Check for fchmod and fchown. Don't check
+ for utimes.
+ * src/extract.c (fdchmod, fdchown, fdstat): New functions.
+ (set_mode, set_stat): New arg FD. All callers changed.
+ This avoids some race conditions between closing a regular file
+ and setting its metadata, and it's a bit faster.
+
+2010-09-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: don't worry about fdopendir closing its argument
+ * NEWS: Don't mention dirfd; no longer needed.
+ * gnulib.modules: Remove dirfd.
+ * src/create.c (get_directory_entries): Remove the code dealing
+ with dirfd failures, as the new fdopendir replacement doesn't
+ close its argument so we don't need to call dirfd. See
+ <http://lists.gnu.org/archive/html/bug-gnulib/2010-09/msg00208.html>
+ and gnulib commit 970c9038e4cca46e1b037ae0a6d574dfae6a7327.
+
+ * NEWS: Fix wording typo in previous change.
+ Reported by Jim Meyering.
+
+ tar: live within system-supplied limits on file descriptors
+ * NEWS: Note the change. Mention dirfd and fdopendir.
+ * gnulib.modules: Add dirfd and fdopendir. The code was already
+ using fdopendir; dirfd is a new need.
+ * src/common.h (open_searchdir_flags, get_directory_entries):
+ (subfile_open, restore_parent_fd, tar_stat_close): New decls.
+ (check_exclusion_tags): Adjust signature to match code change.
+ * src/create.c (IMPOSTOR_ERRNO): New constant.
+ (check_exclusion_tags): First arg is now a struct tar_stat_info
+ const *, not an fd. All callers changed.
+ (dump_regular_file, dump_file0): A zero fd represents an unused
+ slot, so play it safe if the fd member is zero here. A negative
+ fd represents the negation of an errno value, so play it safe and
+ do not assign -1 to fd merely because an open fails.
+ (open_failure_recover, get_directory_entries, restore_parent_fd):
+ (subfile_open): New functions. These help to recover from file
+ descriptor exhaustion.
+ (dump_dir, dump_file0): Use them.
+ (dump_file0): Use tar_stat_close instead of rolling our own close.
+ * src/incremen.c (scan_directory): Use get_directory_entries,
+ subfile_open, etc., to recover from file descriptor exhaustion.
+ * src/names.c (add_hierarchy_to_namelist): Likewise.
+ (collect_and_sort_names): A negative fd represents the negation
+ of an errno value, so play it safe and do not assign -1 to fd.
+ * src/tar.c (decode_options): Set open_searchdir_flags.
+ Add O_CLOEXEC to all the open flags.
+ (tar_stat_close): New function, which knows how to deal with
+ new convention for directory streams and file descriptors.
+ Diagnose 'close' failures.
+ (tar_stat_destroy): Use it.
+ * src/tar.h (struct tar_stat_info): New member dirstream.
+ fd now has the negative of an errno value, not merely -1, if
+ the file could not be opened, so that failures to reopen
+ directories
+ are better-diagnosed later.
+ * tests/Makefile.am (TESTSUITE_AT): Add extrac11.at.
+ * tests/testsuite.at: Likewise.
+ * tests/extrac11.at: New file.
+

+
+2010-09-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: more reliable directory traversal when creating archives
+ * NEWS: Document this.
+ * gnulib.modules: Add openat, readlinkat.
+ * src/common.h (open_read_flags, fstatat_flags): New global
+ variables.
+ (cachedir_file_p, dump_file, check_exclusion_tags,
+ scan_directory):
+ Adjust to new signatures, described below.
+ (name_fill_directory): Remove.
+ * src/compare.c (diff_file, diff_multivol): Use open_read_flags.
+ * src/create.c (struct exclusion_tag): Exclusion predicates
+ now take
+ a file descriptor, not a file name.
+ (add_exclusion_tag): Likewise. All uses changed.
+ (cachedir_file_p): Likewise.
+ (check_exclusion_tags): The directory is now a file descriptor,
+ not a file name. All uses changed. Use openat for better
+ traversal.
+ (file_dumpable_p): Arg is now a struct stat, not a struct
+ tar_stat_info. All uses changed. Check the arg's file types too.
+ (dump_dir0, dump_dir, dump_file0, dump_file): Omit top_level and
+ parent_device args, since st->parent tells us that now. All uses
+ changed.
+ (dump_dir): Likewise. Also, omit fd arg for similar reasons.
+ Apply fdsavedir to a dup of the file descriptor, since we need a
+ file descriptor for openat etc. as well, and fdsavedir (perhaps
+ unwisely) consumes its file descriptor when successful.
+ Do not consume st->fd when successful; this simplifies the caller.
+ (create_archive): Allocate a file descriptor when retraversing
+ a directory, during incremental dumps.
+ (dump_file0): Use fstatat, openat, and readlinkat for better
+ traversal.
+ When opening a file, use the result of fstat on the file
+ descriptor
+ rather than the fstatat on the directory entry, to avoid some race
+ conditions. No need to reopen the directory since we now
+ no longer
+ close it. Change "did we open the file?" test from 0 <= fd to
+ 0 < fd since fd == 0 now represents uninitialized.
+ (dump_file): Now accepts struct tar_stat_info describing parent,
+ not parent_device. Also, accept basename and fullname of entry.
+ All uses changed.
+ * src/incremen.c (update_parent_directory): Accept struct
+ tar_stat_info for parent, not name. All callers changed.
+ Use fstatat for safer directory traversal.
+ (procdir): Accept struct tar_stat_info, not struct stat and
+ dev_t, for info about directory. All callers changed.
+ (scan_directory): Accept struct tar_stat_info, not name,
+ device, and cmdline, for info about directory. All callers
+ changed. Do not consume the file descriptor, since caller
+ might need it. Use fstatat and openat for safer directory
+ traversal; also, use fstat after opening to double-check.
+ (name_fill_directory): Remove.
+ * src/names.c (add_hierarchy_to_namelist): Accept struct
+ tar_stat_info instead of device and cmdline. All callers changed.
+ When descending into a subdirectory, use openat and fstat for
+ safer directory traversal.
+ (collect_and_sort_names): Use open and fstat for safer directory
+ traversal. Set up struct tar_stat_info for callee's new API.
+ * src/tar.c (decode_options): Initialize open_read_flags
+ and fstatat_flags.
+ (tar_stat_destroy): Close st->fd if it is positive (not zero!).
+ * src/tar.h (struct tar_stat_info): New members parent, fd.
+ * src/update.c (update_archive): Adjust to dump_file's API change.
+ * tests/filerem02.at: Ignore stderr since its contents now depend
+ on the file system implementation.
+
+2010-09-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: remove lint discovered by Sun C compiler
+ * src/common.h (WARN_ALL): Don't mask with 0xffffffff; on a 32-bit
+ host, 0xffffffff is of type 'unsigned int', which makes WARN_ALL
+ an unsigned int value that is too large to fit into an int, and
+ the C standard says that this has undefined behavior. The mask is
+ not needed, so omit it.
+
+2010-09-04 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: restore macros that are used in some cases
+ * src/tar.c (LOW_DENSITY_NUM, MID_DENSITY_NUM, HIGH_DENSITY_NUM):
+ Restore these macros, undoing the previous change to this file.
+ The macros are used after all, in some cases. Sorry about that.
+
+2010-09-03 Paul Eggert <eggert@cs.ucla.edu>

+ * src/incremen.c (DIR_IS_NEW): Comment out; not used.

+
+2010-08-27 Sergey Poznyakoff <gray@gnu.org.ua>

+
+ tar: avoid assumptions about root access and chmod -w in test
+ cases
+ * tests/extrac07.at, tests/extrac09.at, tests/listed03.at: Use
+ AT_UNPRIVILEGED_PREREQ, since this test requires non-root
+ privileges.
+ * tests/extrac07.at: Don't use "chmod -w", as POSIX says it's not
+ portable to start a chmod permissions-list with "-" as it may be
+ confused with an option. Use "chmod a-w" instead.
+
+ tar: fix bug with -C and delayed setting of metadata
+ * src/common.h (chdir_current): New decl.
+ * src/extract.c (struct delayed_set_stat, struct delayed_link):
+ New member change_dir.
+ (delay_set_stat, create_placeholder_file): Set it.
+ (apply_nonancestor_delayed_set_stat, apply_delayed_links): Use it.
+ (extract_link): Check that the links are all relative to the same
+ directory.
+ (extract_archive): Restore the current directory after
+ apply_nonancestor_delayed_set_stat has possibly changed it.
+ * src/misc.c (chdir_current): New external var; this used to
+ be the private static variable 'previous' inside chdir_dir.
+ All uses changed.
+ * tests/Makefile.am (TESTSUITE_AT): New test extrac10.at.
+ * tests/extrac10.at: New file.

+ * tests/Makefile.am, tests/testsuite.at: Add xform01.at
+
+2010-08-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ tar: optimize -c --sparse when file is entirely sparse
+ * src/sparse.c (sparse_scan_file): If the file is entirely sparse,

+ blocks. Idea by Kit Westneat, communicated by Bernd Schubert in
+ <http://lists.gnu.org/archive/html/bug-tar/2010-08/msg00038.html>.
+ Also, omit unnecessary lseek at start of file.
+
+ tar: don't assume size of a sparse file chunk fits in size_t
+ * src/tar.h (struct sp_array): Change numbytes from size_t
+ to off_t.
+ All uses changed.
+ * scripts/xsparse.c (struct sp_array): Likewise.
+ Include <stdint.h>, for SIZE_MAX.
+ (expand_sparse): Don't try to allocate a buffer bigger than

+ * src/xheader.c (sparse_numbytes_decoder, sparse_map_decoder):
+ Likewise.
+

+ * src/extract.c (struct delayed_link): Rename member mtime

+ The idea was suggested by Petr Sumbera in the thread starting
+ here:
+ http://lists.gnu.org/archive/html/bug-tar/2010-08/msg00000.html
+ * src/extract.c (set_mode): Save the errno of the chmod that

+ retrying chmod unless the mode suggests setuid is the issue.
+ (extract_archive): Remove redundant call to

+
+ tar: handle files that occur multiple times but have link count 1
+ This patch was inspired by the following patch that addressed a

+ * src/common.h (name_count): New decl.
+ * src/create.c (trivial_link_count): New static var.
+ (create_archive): Initialize it.
+ (dump_hard_link, file_count_links): Use it, so that files with
+ link count 1 are handled correctly when they are found multiple
+ times.
+ * src/names.c (allocated_entries): Renamed from allocated_names,
+ since the identifier's name was misleading. All uses changed.
+ (entries): Renamed from names. All uses changed.
+ (scanned): Renamed from name_index. All uses changed.
+ (name_count): New var.

+
+ Fix --remove-files.
+ Tar --remove-files relied on canonicalize_file_name,
+ which replaces symlinks in file name components with
+ the directories they point to. Due to this, tar
+ effectively ignored existence of symbolic links and

+ (Alexander Kozlov <akozlov@nada.kth.se>, 2010-03-15).
+ * gnulib.modules: Remove canonicalize.
+ * src/misc.c (normalize_filename): Rewrite
