2011-03-12 Sergey Poznyakoff Version 1.26 * NEWS, configure.ac: Update. * po/POTFILES.in: Remove paxexit.c (see bb971a1e). 2011-03-08 Paul Eggert --atime-preserve=replace: fix correctness and performance bugs reported by Eric Blake in . * src/compare.c (diff_file): Do not restore atime of size-zero files. * src/create.c (dump_file0): Likewise. Also, do not restore atime when fd is zero, because that indicates a file we haven't opened. 2011-02-23 Paul Eggert * doc/tar.texi: Adjust example commands and output for accuracy. The original problem was reported by Michael Witten in . 2011-02-16 Paul Eggert tar: if (p) free (p); -> free (p); There is no longer (since SunOS 4) any need to guard against free (NULL), so replace each "if (p) free (p);" with "free (p);". From Jim Meyering in . * src/incremen.c (scan_directory, read_directory_file): As above. (try_purge_directory): Likewise. * src/list.c (read_header): Likewise. * src/misc.c (assign_string): Likewise. 2010-12-14 Sergey Poznyakoff Correctly store long sparse file names in PAX archives. * src/sparse.c (pax_dump_header_1): Make sure the created header name is shorter than NAME_FIELD_SIZE bytes. * tests/sparse04.at: New testcase. * tests/Makefile.am (TESTSUITE_AT): Add sparse04.at. * tests/testsuite.at: Include sparse04.at. * NEWS: Update. 2010-12-07 Paul Eggert tests: make the truncate test smaller and less buggy (tiny change) Reported by Solar Designer in . * tests/truncate.at: Use a smaller test case, and make its race condition less likely. 2010-11-27 Paul Eggert tests: skip SIGPIPE-dependent tests in environments ignoring SIGPIPE Problem reported by Sven Joachim in . * tests/remfiles01.at: Use AT_SIGPIPE_PREREQ. * tests/sigpipe.at: Likewise. * tests/testsuite.at (AT_SIGPIPE_PREREQ): New macro. 2010-11-25 Paul Eggert tar: work around NetBSD and Tru64 symlink incompatibility with POSIX Problem reported by Bruno Haible in . * src/extract.c (maybe_recoverable): Also treat EFTYPE (if defined) and ENOTSUP like ELOOP. 2010-11-24 Paul Eggert tar: adjust to paxutils change: paxexit.c -> paxexit-status.c * lib/Makefile.am (libtar_a_SOURCES): paxexit.c renamed to paxexit-status.c. tar: remove unused function dir_removed_diag * src/common.h (dir_removed_diag): Remove unused decl. * src/misc.c (dir_removed_diag): Remove unused function. 2010-11-23 Paul Eggert tar: work around FreeBSD symlink incompatibility with POSIX * src/extract.c (maybe_recoverable): Treat EMLINK like ELOOP, for FreeBSD. Problem reported by Christian Weisgerber in . * src/names.c: tar: fix bug with --one-file-system --listed-incremental Problem (and idea for fix) reported by Martin Weigel . * src/common.h (is_individual_file): Remove decl. * src/create.c (dump_file0): Replace "is_individual_file (p)" with "top_level". * src/incremen.c (procdir): Replace "!is_individual_file (name_buffer)" with "st->parent". Fix bug with --one-file-system and --listed-incremental. * src/names.c (individual_file_table, register_individual_file): (is_individual_file): Remove. All uses removed. tests: new test listed04 for --one-file-system --listed-incremental * tests/Makefile.am (TESTSUITE_AT): Add listed04.at. * tests/listed04.at: New file. * tests/testsuite.at: Include it. scripts: fix option parsing Problem reported by Dennis Wydra in . * scripts/backup.in: Accept "-l LEVEL". Be more systematic about backslashes inside ``; it shouldn't matter for modern shells but it might matter for older ones. * scripts/restore.in: Likewise. * scripts/backup.in: Adjust implementation of -t/--time to match the new implementation of -l/--level. 2010-11-15 Sergey Poznyakoff Issue a warning if the archive being compared contais transformed file names. * src/common.h (transform_program_p): New proto. * src/transform.c (transform_program_p): New function. * src/compare.c (verify_volume): Warn if the archive contains transformed file names. Minor change. * doc/tar.texi: Reword the description of decompress-program. 2010-11-15 Paul Eggert tar: fix --verify option, which broke in 1.24 * NEWS: Document this. * src/compare.c (verify_volume): Decode the header before invoking diff_archive, as diff_archive no longer does this as of the 2010-06-28 commit. Also, don't try to invoke diff_archive on a zero block. * tests/Makefile.am (TESTSUITE_AT): Add verify.at. * tests/testsuite.at: Include verify.at. * tests/verify.at: New file. 2010-11-08 Paul Eggert Merge branch 'master' of ssh://git.sv.gnu.org/srv/git/tar 2010-11-08 Jim Meyering tests: avoid spurious failure when VERSION_CONTROL envvar is set * tests/backup01.at: Unset VERSION_CONTROL. Otherwise, when set to e.g., 'always', it would cause this test to fail. 2010-11-07 Sergey Poznyakoff Version 1.25 * configure.ac: Version 1.25 * NEWS: Describe the changes. 2010-11-05 Sergey Poznyakoff 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. (archive_compression_type): New static variable. (zip_magic): Remove program and option fields. (zip_program): New structure and static. (compress_program): Remove macro. (find_zip_program): New static function. (first_decompress_program,next_decompress_program): New functions. (open_compressed_archive): Set archive_compression_type instead of use_compress_program_option. * src/common.h (first_decompress_program) (next_decompress_program): New functions. (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 tests: fix some issues with signals, timestamps, "test" typo * tests/extrac17.at: Add --warning=no-timestamp, to avoid bogus warning due to NFS clock skew. * 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 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 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 . * 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 ; solution suggested by Jilles Tjoelker in . * tests/extrac11.at (scarce file descriptors): Close file descriptors before invoking ulimit -n. 2010-10-27 Sergey Poznyakoff Transform file names when updating and appendig to archives. This complements 28e91b48. * src/common.h (transform_stat_info): New prototype. * src/list.c (transform_stat_info): Remove static qualifier. * src/update.c (update_archive): Call transform_stat_info. * tests/Makefile.am (TESTSUITE_AT): Add append03.at * tests/testsuite.at: Include append03.at 2010-10-27 Paul Eggert 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 encounted". 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 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. 2010-10-26 Paul Eggert tar: don't assume stdin is open when testing fd limits * tests/extrac11.at: Redirect stdin from /dev/null, in case the parent 'make' is running with stdin closed. 2010-10-26 Sergey Poznyakoff Further fixes in bootstrap. * bootstrap: Restore the default for gnulib_path (symlink_to_dir): Re-apply 67cad07. 2010-10-26 Paul Eggert tar: fix bug with -C and extracting directories Problem reported by Denis Excoffier in . * src/extract.c (extract_dir): Use mkdirat, not mkdir. * tests/extrac16.at: New file, to test for this bug. * tests/Makefile.am (TESTSUITE_AT): Add it. * tests/testsuite.at: Include it. This file is a placeholder. It will be replaced with the actual ChangeLog by make dist. Run make ChangeLog if you wish to create it earlier. 2010-10-25 Sergey Poznyakoff Version 1.24 * configure.ac, NEWS: Version 1.24 * bootstrap: Restore tar-specific code lost during last sync from gnulib (241b72ffad). * src/misc.c (chdir_do): Remove unused automatic variable. 2010-10-16 Paul Eggert 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 . * 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. * tests/chtype.at, tests/comprec.at, tests/exclude06.at: * tests/extrac01.at, tests/extrac03.at, tests/extrac05.at: * tests/extrac06.at, tests/extrac08.at, tests/extrac13.at: * tests/extrac14.at, tests/incr01.at, tests/incr03.at, tests/link01.at: * tests/multiv01.at, tests/multiv02.at, tests/multiv03.at: * tests/pipe.at, tests/rename02.at, tests/rename03.at: * tests/rename05.at, tests/same-order01.at, tests/same-order02.at: * tests/sparse01.at: Likewise. 2010-10-12 Paul Eggert gnulib: sync from latest gnulib, notably bootstrap and parse-datetime * bootstrap: Sync from gnulib. * doc/.gitignore: Rename getdate.texi to parse-datetime.texi. * doc/Makefile.am (tar_TEXINFOS): Likewise. * doc/tar.texi (Top): Adjust to renaming of getdate to parse-datetime. * gnulib.modules: Likewise. Also, remove ftruncate (now obsolete). And add inttostr (we missed this dependency). * src/tar.c: Include parse-datetime.h, not getdate.h. All calls to get_date replaced with parse_datetime. 2010-09-24 Paul Eggert tar: -x -C symlink fix * src/misc.c (chdir_do): Don't use O_NOFOLLOW when opening the argument to -C. This is for consistency with "tar -c -C FOO", and 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. 2010-09-20 Paul Eggert tar: do not crash with --listed-incremental Problem reported by Frantisek Hanzlik in via Kamil Dudka in . 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 the time. * src/incremen.c (append_incremental_renames): Don't actually append anything to DIR if DIR is null. 2010-09-19 Paul Eggert 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/update.c (append_file): Likewise. * src/compare.c (diff_symlink): Use readlinkat instead of readlink. * 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 ; 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 ChangeLog by make dist. Run make ChangeLog if you wish to create it earlier. 2010-09-18 Paul Eggert tar: add utimens.h includes * src/extract.c: Include , 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 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 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 inadvertantly. * 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 * 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 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 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. 2010-09-08 Paul Eggert tar: improve documentation of reliability and security issues * doc/tar.texi (Reliability and security, Reliability): (Permissions problems, Data corruption and repair, Race conditions): (Security, Privacy, Integrity, Live untrusted data): (Security rules of thumb): New nodes. 2010-09-06 Paul Eggert 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 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 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 tar: remove unused macros * src/create.c (UINTMAX_TO_CHARS): Remove; no longer used. * src/tar.c (LOW_DENSITY_NUM, MID_DENSITY_NUM, HIGH_DENSITY_NUM): Likewise. * src/incremen.c (DIR_IS_NEW): Comment out; not used. Mark this with a FIXME, since it looks like it should be used. 2010-08-27 Sergey Poznyakoff Fix --remove-files in update/append mode. * src/update.c (update_archive): Call finish_deferred_unlinks when done. 2010-08-26 Paul Eggert 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/testsuite.at: Include it. 2010-08-25 Sergey Poznyakoff Don't apply file transformations to volume names. * src/list.c (decode_header): Don't apply file transformations to volume names. * tests/xform01.at: New testcase. * tests/xform-h.at (xform): Rename macro to xformtest. Use pushdef/popdef. * tests/Makefile.am, tests/testsuite.at: Add xform01.at 2010-08-25 Paul Eggert tar: optimize -c --sparse when file is entirely sparse * src/sparse.c (sparse_scan_file): If the file is entirely sparse, that is, if ST_NBLOCKS is zero, don't bother scanning for nonzero blocks. Idea by Kit Westneat, communicated by Bernd Schubert in . 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 , for SIZE_MAX. (expand_sparse): Don't try to allocate a buffer bigger than SIZE_MAX bytes. * src/common.h (SIZE_TO_CHARS, size_to_chars, SIZE_FROM_HEADER): (size_from_header): Remove decls. * src/create.c (size_to_chars): Remove. * src/list.c (size_from_header): Remove. * src/sparse.c (sparse_extract_region, check_data_region): (oldgnu_add_sparse, oldgnu_store_sparse_info, pax_decode_header): Don't assume chunk sizes fit in size_t. (oldgnu_add_sparse): Check for off_t overflow. * src/xheader.c (sparse_numbytes_decoder, sparse_map_decoder): Likewise. tar: use ctime, not mtime, when checking placeholders * src/extract.c (struct delayed_link): Rename member mtime to ctime. All uses changed to use ctime rather than mtime. 2010-08-24 Paul Eggert tar: add comment to link04.at test * tests/link04.at: Add explanatory comment at head. tar: fix 1.23 Solaris regression related to PRIV_SYS_LINKDIR 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 failed, for the benefit of chmod_error_details. Do not bother retrying chmod unless the mode suggests setuid is the issue. (extract_archive): Remove redundant call to priv_set_remove_linkdir. * src/system.c: Include priv-set.h. (sys_spawn_shell, sys_child_open_for_compress): (sys_child_open_for_uncompress, sys_exec_command): (sys_exec_info_script, sys_exec_checkpoint_script): Invoke priv_set_restore_linkdir before execv or execlp, so that the subprocess has the same privileges that tar originally did. tar: handle files that occur multiple times but have link count 1 This patch was inspired by the following patch that addressed a similar problem in GNU coreutils du: http://git.savannah.gnu.org/gitweb/?p=coreutils.git;h=efe53cc72b599979ea292754ecfe8abf7c839d22 * 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. (name_add_name): Increment it. * tests/link04.at: New file. * tests/testsuite.at: Add it. * tests/Makefile.am (TESTSUITE_AT): Likewise. 2010-08-23 Paul Eggert tar: use nlink_t for link counts * src/create.c (struct link): nlink is now of type nlink_t, not size_t. tar: don't export names that aren't used elsewhere * src/common.h (file_dumpable_p, gid_to_chars, major_to_chars): (minor_to_chars, mode_to_chars, uid_to_chars, uintmax_to_chars): (string_to_chars, dumpdir_creat0, dumpdir_create, dumpdir_free): (dumpdir_locate, dumpdir_next, dumpdir_first, gid_from_header): (major_from_header, minor_from_header, mode_from_header): (time_from_header, uid_from_header, quote_copy_string, request_stdin): (xheader_init, transform_header_name): Remove declarations; these are no longer exported from their modules. (GID_TO_CHARS, MAJOR_TO_CHARS, MINOR_TO_CHARS, MODE_TO_CHARS): (UID_TO_CHARS, UINTMAX_TO_CHARS, UNAME_TO_CHARS, GNAME_TO_CHARS): Move to src/create.c, since no other module uses these. (GID_FROM_HEADER, MAJOR_FROM_HEADER, MINOR_FROM_HEADER): (MODE_FROM_HEADER, TIME_FROM_HEADER, UID_FROM_HEADER): Move to src/extract.c, since no other module uses these. (dumpdir_t, dumpdir_iter_t): Remove; no longer used. * src/create.c (gid_to_chars, major_to_chars, minor_to_chars): (mode_to_chars, uid_to_chars, uintmax_to_chars, string_to_chars): (file_dumpable_p): Now static. * src/incremen.c (dumpdir_create0, dumpdir_create, dumpdir_free): (dumpdir_locate, dumpdir_next, dumpdir_first): Now static. (scan_directory, write_directory_file_entry): Use struct dumpdir_iter * rather than dumpdir_iter_t. * src/list.c (gid_from_header, major_from_header, minor_from_header): (mode_from_header, time_from_header, uid_from_header): (transform_member_name): Now static. * src/misc.c (quote_copy_string): #if 0 out, as it's not used anywhere. * src/system.c (wait_for_grandchild): Now static. * src/tar.c (request_stdin): Now static. * src/xheader.c (xheader_init): Now static. tar: fix misspelled identifier "set_comression_program_by_suffix" * src/suffix.c (set_compression_program_by_suffix): Renamed from set_comression_program_by_suffix. * src/buffer.c, src/common.h, src/tar.c: All uses changed. 2010-08-20 Paul Eggert tar: change interdir_made from int to bool * src/extract.c (maybe_recoverable, create_placeholder_file): Change interdir_made from int * to bool *, since the flag has just two values 0 and 1. All uses changed. This does not affect tar's behavior. tar: remove trailing white space from source files * ChangeLog.1, ChangeLog.CVS, Makefile.am, NEWS, README: * README-hacking, directory, doc/Makefile.am, doc/dumpdir.texi: * doc/gendocs_template, doc/intern.texi, doc/mastermenu.el: * doc/snapshot.texi, doc/sparse.texi, doc/tar-snapshot-edit.texi: * doc/value.texi, lib/Makefile.am, scripts/backup-specs: * scripts/dump-remind.in, scripts/tar-snapshot-edit, scripts/tarcat: * scripts/xsparse.c, src/arith.h, src/buffer.c, src/compare.c: * src/create.c, src/delete.c, src/exit.c, src/suffix.c, src/tar.c: * src/tar.h, src/update.c, src/warning.c, src/xheader.c: * tests/append01.at, tests/append02.at, tests/atlocal.in: * tests/delete03.at, tests/exclude.at, tests/exclude06.at: * tests/extrac04.at, tests/extrac05.at, tests/extrac06.at: * tests/extrac07.at, tests/filerem01.at, tests/filerem02.at: * tests/incr01.at, tests/incr02.at, tests/incr03.at, tests/incr06.at: * tests/label02.at, tests/label03.at, tests/label04.at: * tests/label05.at, tests/link02.at, tests/link03.at: * tests/listed01.at, tests/listed02.at, tests/long01.at: * tests/longv7.at, tests/multiv01.at, tests/multiv02.at: * tests/multiv03.at, tests/multiv05.at, tests/multiv06.at: * tests/multiv07.at, tests/multiv08.at, tests/options.at: * tests/options02.at, tests/remfiles03.at, tests/rename01.at: * tests/rename02.at, tests/rename03.at, tests/rename04.at: * tests/rename05.at, tests/same-order01.at, tests/same-order02.at: * tests/shortfile.at, tests/shortupd.at, tests/sparse01.at: * tests/sparse02.at, tests/sparsemv.at, tests/sparsemvp.at: * tests/star/README, tests/star/gtarfail2.at: * tests/star/multi-fail.at: * tests/star/pax-big-10g.at, tests/star/quicktest.sh: * tests/star/ustar-big-2g.at, tests/star/ustar-big-8g.at: * tests/update01.at, tests/update02.at, tests/volsize.at: * tests/volume.at: Remove trailing spaces and tabs from lines, and remove trailing empty lines from files. This makes it a bit easier to share code among coreutils and other projects that do this. 2010-08-19 Paul Eggert tar: update licenses to latest versions from www.gnu.org * COPYING: Update to latest version; this is just minor formatting. * doc/fdl.texi: Update from GFDL 1.2 to 1.3. * doc/tar.texi: Adjust to new format of fdl.texi. Omit trailing white space. 2010-07-18 Paul Eggert * src/misc.c (struct wd): Fix comment to match code. 2010-07-18 Paul R. Eggert tar: no need to report getcwd error if never using the result * src/misc.c (struct wd): Rename 'saved' to 'err', with new semantics. (chdir_arg, chdir_do): Adjust to new semantics. Do not report an error merely because save_cwd fails; report an error only if save_cwd's result is needed later. * tests/extrac09.at: New file, to test for bug that was fixed. * tests/testsuite.at: Include it. * tests/Makefile.am (TESTSUITE_AT): Add it. tar: go back to absolutifying filenames in normalize_filename for now * src/misc.c (normalize_filename): For now, go back to making filenames absolute, even though this causes 'tar' to fail when getcwd fails. However, do not attempt to resolve ".." as this does not work with symlinks. Also, do the right thing with leading file system prefixes and on hosts where // != /. 2010-07-17 Sergey Poznyakoff Allow for size suffixes in -L and --record-size options. * src/tar.c (TAR_SIZE_SUFFIXES): New define. (parse_opt): Allow for size suffixes in arguments to -L and --record-size options. * NEWS, doc/tar.texi: Update. 2010-07-15 Paul R. Eggert tar: don't crash if getcwd fails * src/extract.c: Don't include xgetcwd.h. (extract_dir): stat "." rather than statting getcwd's output. * src/misc.c (normalize_filename_x): Rewrite so as not to resolve /../, which can't be done reliably in the presence of symlinks. Don't reject valid names such as ".". (normalize_filename): Don't make it absolute; that way, we don't have to invoke xgetcwd which might fail. Don't bother to realloc at the end, since that uses time and now saves little space. (chdir_do): Don't crash if xgetcwd fails. * tests/Makefile.am (TESTSUITE_AT): Add listed03.at. * tests/listed03.at: New file. * tests/testsuite.at: Include listed03.at. 2010-07-11 Sergey Poznyakoff Keep a detailed map of archive members stored in the record buffer. A separate map (bufmap) provides information for creating multi-volume continuation headers. * src/buffer.c (bufmap): New struct. (bufmap_head, bufmap_tail, inhibit_map): New variables. (mv_begin_write): New function. (mv_begin): Rename to mv_begin_read. Rewrite using mv_begin_write. All callers changed. (mv_total_size): Remove.

(multi_volume_sync): Remove. * src/common.h (mv_begin_write): New prototype. (mv_begin): Rename to mv_begin_read. * src/create.c: Use mv_begin_write instead of mv_begin. Remove calls to mv_size_left and mv_end. * src/sparse.c: Likewise. * tests/multiv07.at: Close stdin. * tests/spmvp00.at: Update AT_KEYWORDS. * tests/spmvp10.at: Likewise. * tests/multiv08.at: New testcase. * tests/Makefile.am, tests/testsuite.at: Add multiv08.at. Version 1.23.90 * NEWS, configure.ac: Version 1.23.90 * doc/tar.texi: Document the use of lbzip2. 2010-06-28 Sergey Poznyakoff Fix exclusion of long file names when extracting from pax format archives. * src/list.c (read_and): Call decode_header before attempting name_match. (list_archive): Remove call to decode_header. * src/compare.c (diff_archive): Remove call to decode_header. * src/extract.c (extract_archive): Likewise. * test/exclude06.at: New test case. * tests/testsuite.at: Include exclude06.at. * tests/Makefile.am (TESTSUITE_AT): Add exclude06.at. Minor fix. * src/buffer.c (magic): Split the character constant to help cc recognize character boundaries (7 is a valid hex character). 2010-06-27 Sergey Poznyakoff Minor fix. * src/buffer.c (magic): Fix xz magic. 2010-06-16 Paul Eggert Remove some lint, found by gcc -W etc. * src/common.h (label_notfound): New decl. * src/buffer.c (set_volume_start_time, compress_type): (guess_seekable_archive, open_compressed_archive, init_buffer): (_flush_write, archive_is-dev, increase_volume_number): (change_tape_menu, try_new_volume, add_chunk_header): (multi_volume_sync): Declare as 'static' if it's not exported. Use function prototype (void) rather than old-style (). * src/checkpoint.c (expand_checkpoint_string): Likewise. * src/incremen.c (dirlist_replace_prefix, makedumpdir, read_incr_db_2): Likewise. * src/list.c (print_volume_label): Likewise. * src/misc.c (normalize_filename_x): Likewise. * src/names.c (make_name, free_name, check_name_alloc, name_next_elt): Likewise. * src/tar.c (tar_list_quoting_style, add_exclude_array): (set_stat_signal): Likewise. * src/transform.c (new_transform, _single_transform_name_to_obstack): (_transform_name_to_obstack): Likewise. * src/unlink.c (dunlink_alloc): Likewise. * src/buffer.c (struct zip_magic): Use const when appropriate. * src/incremen.c (obstack_code_rename, write_directory_file_entry): Likewise. * src/sparse.c (COPY_STRING): Likewise. * src/system.c (dec_to_env, time_to_env, oct_to_env, str_to_env): (chr_to_env): Likewise. * src/tar.c (tar_list_quoting_style, set_stat_signal): Likewise. * src/extract.c (extract_node): Don't return garbage. * src/names.c: Remove old-style declarations of getgrnam etc. All modern systems declare these, and it's not worth the hassle of ignoring the warnings on modern systems for old-style decls. 2010-05-17 Sergey Poznyakoff Bugfix. * src/incremen.c (make_directory): Retain the slash if it is the only character in a filename. 2010-04-02 Sergey Poznyakoff Recode NEWS back to UTF-8 2010-04-01 Sergey Poznyakoff Fix the gzip.at test case. * tests/gzip.at: Suppress gzip error output, as it can differ depending on its version etc. Bug reported by Ludovic Courtès. 2010-03-28 Sergey Poznyakoff New option --full-time. * src/common.h (full_time_option): New global. * src/tar.c (FULL_TIME_OPTION): New constant. (options): New option --full-time. (parse_opt): Handle the --full-time option. * src/list.c (simple_print_header): Pass full_time_option as the 2nd argument to tartime. * doc/tar.texi: Update. * NEWS: Update. 2010-03-27 Sergey Poznyakoff Minor fixes in the testsuite. * tests/extrac07.at: Fix a typo (invalid number of arguments before format list). * tests/link02.at: Use `ln' instead of `link'. * tests/link03.at: Likewise. Fix coredump. * src/names.c (collect_and_sort_names): Remove entry from the table before freeing it. Fix dead loop on extracting existing symlinks with the -k option. * src/extract.c (create_placeholder_file) (extract_link, extract_symlink) (extract_node, extract_fifo): Handle all possible return values from maybe_recoverable. This complements 8f390db92fc. Reported by Ico Doornekamp . * NEWS: Update. 2010-03-20 Sergey Poznyakoff Fix undesired error exit on receiving SIGPIPE. * src/tar.c: Do not ignore SIGPIPE. * tests/sigpipe.at: New testcase. * tests/Makefile.am, tests/testsuite.at: Add sigpipe.at * tests/remfiles01.at: Fix error code expectation. * NEWS: Update. 2010-03-17 Sergey Poznyakoff 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 was unable to remove a directory that contained any (Alexander Kozlov , 2010-03-15). * gnulib.modules: Remove canonicalize. * src/misc.c (normalize_filename): Rewrite from scratch. The function operates only on its input string, it makes no attempt to test components for existence or to resolve symbolic links. * tests/Makefile.am (TESTSUITE_AT): Add remfiles03.at. * tests/testsuite.at: Likewise. * tests/remfiles03.at: New test case. * NEWS: Update. 2010-03-12 Sergey Poznyakoff Bugfixes. * src/buffer.c (check_label_pattern): Initialize result. * tests/remfiles01.at: Skip if run with root privileges. 2010-03-11 Sergey Poznyakoff Fix `--test-label' and `--label -r' behavior. * doc/tar.texi (Including a Label in the Archive): Revise the section. * NEWS: Update * src/buffer.c (open_archive): Check volume label on ACCESS_UPDATE as well. * src/list.c (test_archive_label): Rewrite to match the documentation. * src/names.c (regex_usage_warning): Return int. (names_notfound): Rewrite the conditional. (label_notfound): New function. * tests/label03.at: New testcase. * tests/label04.at: New testcase. * tests/label05.at: New testcase. * tests/Makefile.am: Add new testcases. * tests/testsuite.at: Likewise. Doc fixes. * doc/tar.texi: Consistently use lowercase `see' within sentences. More fixes spotted by Denis Excoffier. * THANKS: Update. Shut up a gcc warning message. * src/tar.c (tar_help_filter): Use a separate const variable to hold returns from gettext. Reported by Peter Breitenlohner. Bugfix. * src/names.c (collect_and_sort_names): Initialize prev_name. Reported by Dmitry V. Levin. 2010-03-10 Sergey Poznyakoff Version 1.23 * configure.ac, NEWS: Update version number. Doc changes. * NEWS: Update. * THANKS: Update. * doc/snapshot.texi, doc/snapshot.texi, doc/sparse.texi, doc/tar-snapshot-edit.texi, doc/tar.texi: Spellchecked and proof-read. Thanks to Denis Excoffier. * gnulib.modules: Remove utime. 2010-03-08 Kamil Dudka Fix possible overflow in code_timespec (tiny change) * src/misc.c (code_timespec): ignore invalid values of ns 2010-03-08 Sergey Poznyakoff Minor fix in the testsuite. * tests/extrac05.at: Skip test if creating sparse file fails. Fix eventual memory override and fd exhaustion in create.c Both bugs reported by Kamil Dudka. * src/create.c (check_exclusion_tags): Do not keep pointer to a location within tagname: it may change after xrealloc.

Fix condition for selecting candidates for removal. * README-alpha: List texinfo among build prerequisites for the CVS version. * bootstrap (intl_files_to_remove): Do not remove m4/inttypes-h.m4 and m4/inttypes-pri.m4 2006-08-11 Paul Eggert * bootstrap: Set XGETTEXT_OPTIONS to flag our printf-format functions, so that translators are warned about strings that are formats but don't look like formats. This might help prevent core dumps. * configure.ac (AM_GNU_GETTEXT): Upgrade to need-formatstring-macros. Suggested by Eric Blake to avoid problems like . (AM_GNU_GETTEXT_VERSION): Upgrade from 0.12.1 to 0.15. The gettext manual says we should use the version number normally expected of maintainers, neither more nor less. * bootstrap (get_translations): Don't exclude ky.po; it is working again. 2006-08-09 Paul Eggert * bootstrap (get_translations): Don't exclude ja.po; it is working again.

(m4/geteext.m4): Patch to remove the need for intl/*. Use autopoint manually, then remove the intl files, then undo changes to gnulib files that autoreconf made, and then run aclocal/autoconf/autoheader/automake. This makes our bootstrap procedure closer to Bison's. (po/Makevars): Generate automatically. * configure.ac (AC_PREREQ): Update from 2.59 to 2.60. (gl_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Remove. * gnulib.modules: Add inttypes, stdint. * lib/.cvsignore: Add close-stream.c, close-stream.h, stdint.h, stdint_.h. * po/Makefile: Remove; now automatically generated. * src/incremen.c (read_incr_db_01): Check input strings more carefully.

(read_timespec, write_directory_file_entry, write_directory_file): Handle negative time_t values correctly. We don't bother to do this with pre-2 formats, since presumably the time stamps were output incorrectly. * src/tar.c (doc): Don't use \v in an argument to gettext; gettext 0.15 rejects this. 2006-07-24 Sergey Poznyakoff * src/tar.c (decode_options): Do not require -L with -M -Hpax. It could be needed in future, but currently it is not. * src/create.c (to_chars_subst): Update comment regarding OLDGNU vs. GNU format differences. (mode_to_chars): Treat OLDGNU_FORMAT same as GNU_FORMAT. Fixes bug reported by TAMUKI Shoichi , which caused equivalent `tar cf ...' and `tar rf ...' commands to produce different archives. * tests/append02.at: New test case * tests/Makefile.am, tests/testsuite.at: Add append02.at 2006-07-20 Paul Eggert * bootstrap: Adjust to today's change to gnulib-tool by invoking it with --assume-autoconf='latest-stable'. 2006-07-16 Paul Eggert Adjust to recent gnulib changes. * lib/.cvsignore: Remove atexit.c, exit.c, getndelim2.c, getndelim2.h, pathmax.h, paxconvert.c, paxerror.h, xstrdup.c.

Check for stropts.h and sys/filio.h too, for _FIOSATIME. * doc/tar.texi: Change "modification time" to "data modification time", "change time" to "status change time", and "filesystem" to "file system", so that we use terminology consistent with POSIX. Use American spacing rather than French for sentence ends. "non-dependable" -> "undependable".

(diff_file): Use set_file_atime rather than utimens; avoid closing diff_handle until after this, so that we can set the file time stamp via the file descriptor rather than via its name. * src/create.c: Don't include utimens.h; no longer needed. (dump_regular_finish): Remove. All callers now do its work inline. (dump_dir): New arg FD. All callers changed. Use fdsavedir rather than savedir. (unknown_file_error): Arg is a const pointer now. (dump_file0): 2nd arg is a const pointer now. Treat directories more like files, with respect to --atime-preserve. For example, also warn if a directory changes while we are dumping it. Prefer file descriptors to file names when retrieving/setting file attributes; this saves path-resolution time and allows us to avoid changing mtime/ctime on Solaris when restoring atime as root. Use O_DIRECTORY when opening directories, to avoid some race conditions. Do not reset atime if mtime has changed. Report an error if we cannot reset atime. * lib/.cvsignore: Add malloc.h, regcomp.c, regex.c, regex.h, regex_internal.c, regex_internal.h, regexc.c; used by rpmatch. 2005-11-29 Ian Turner First cut at adding support for --atime-preserve=system. * doc/tar.texi (Option Summary): First cut at documenting it.

(xheader_write): Increase global_header_count here ... (xheader_write_global): ... instead of here * tests/testsuite.at (AT_TAR_CHECK): Define TEST_TAR_FORMAT * tests/multiv01.at: Update * tests/multiv02.at: Update * tests/multiv03.at: Update * tests/sparsemvp.at: Update * tests/star/multi-fail.at: Update * scripts/tarcat: Handle archives in pax format. Improve handling of traditional archives. * doc/tar.texi (Tarcat): New node 2005-11-10 Sergey Poznyakoff Fix splitting of sparse files between the volumes. * src/buffer.c (try_new_volume): Bugfix.

NOTICE, that some of the aspects (e.g. splitting the archive on the extended header boundary) are still not solved, others (splitting a sparse file between the volume) require additional testing. Wait for the next commit. (volume_label,continued_file_name,continued_file_size) (continued_file_offset): New globals. (save_name,save_totsize,save_sizeleft): Make static (mv_begin,mv_end,mv_total_size,mv_size_left): New functions (open_archive,flush_write,flush_read): Rewritten * src/common.h (save_name,save_sizeleft,save_totsize): Remove globals.

Problem reported by Eric Blake. 2005-09-16 Paul Eggert Don't filter time stamps through the resolution supported by struct stat; keep them to full nanosecond resolution. This affects behavior only on older hosts or file systems that have lower-resolution time stamps. * src/common.h (OLDER_STAT_TIME): Parenthesize arg. (OLDER_TAR_STAT_TIME): New macro. (code_timespec): New function. (BILLION, LOG10_BILLION, TIMESPEC_STRSIZE_BOUND): New constants. * src/compare.c (diff_file): Use full time stamp resolution. * src/create.c (start_header, dump_file0): Likewise. (start_header, dump_file0): Adjust to new structure layout. (dump_regular_finish): Simplify by using timespec_cmp. * src/extract.c (struct delayed_set_stat): Don't store stat info that we don't need, to save space. All uses changed. (struct delayed_set_stat, struct delayed_link, file_newer_p): (create_placeholder_file, extract_link, apply_delayed_links): Use full time stamp resolution. (check_time): Use code_timespec rather than rolling our own code. (set_stat, delay_set_stat): Arg now points to tar_stat_info to avoid losing time information. All callers changed. * src/list.c (read_and, decode_header, print_heaeder): Use full time stamp resolution. * src/misc.c (code_timespec): New function. * src/tar.h (struct tar_stat_info): Record atime, mtime, ctime separately, for benefit of hosts with lower resolution. * src/update.c (update_archive): Use full time stamp resolution. * src/xheader.c (code_time): Use new code_timespec function to simplify code. (atime_coder, atime_decoder, ctime_coder, ctime_decoder): (mtime_coder, mtime_decoder): Use full time stamp resolution. Report time stamps to full resolution in environment. Report memory allocation failures rather than ignoring them. * src/system.c (time_to_env): New function. (oct_to_env, str_to_env, chr_to_env): Report memory allocation failures. (stat_to_env): Report full resolution in time stamps. 2005-09-16 Paul Eggert Merge changes from gnulib for file system sub-second time stamps. * configure.ac: Remove checks for struct stat.st_spare1, struct stat.st_atim.tv_nsec, struct stat.st_atimespec.tv_nsec, struct stat.st_atimensec, as gnulib now does this for us. Similarly for LIB_CLOCK_GETTIME. * gnulib.modules: Add stat-time. * lib/.cvsignore: Add stat-time.h. * src/common.h: Include stat-time.h. (timespec_lt): Remove. All callers changed to use timespec_cmp. (get_stat_atime, get_stat_ctime, get_stat_mtime): (set_stat_atime, set_stat_ctime, set_stat_mtime): Remove; now defined by stat-time.h. 2005-09-14 Sergey Poznyakoff * src/incremen.c (list_dumpdir): New function. Used to dump contents of GNUTYPE_DUMPDIR blocks. * src/common.h (list_dumpdir): Likewise. * src/list.c (list_archive): Use list_dumpdir() to display GNUTYPE_DUMPDIR blocks. Do that only if two or more -v options are given. 2005-09-12 Paul Eggert * lib/.cvsignore: Adjust to current gnulib and modules used. Add getdelim.c, getdelim.h, mbchar.c, mbchar.h, mbuiter.h, memchr.c, pipe-safer.c, size_max.h, strdup.c, strdup.h, strnlen.h, strnlen1.c, strnlen1.h, unistd--.h. Remove getndelim2.c, getndelim2.h, pathmax.h, sysexits.h, xstrdup.c. Treat fishy-looking hard links like fishy-looking symlinks. * src/extract.c (struct delayed_set_stat): Rename after_symlinks member to after_links. All uses changed. (struct delayed_link): Renamed from struct delayed_symlink. All uses changed. New member is_symlink. (delayed_link_head): Renamed from delayed_symlink_head. All uses changed.

Call sparse_select_optab(). All callers updated. (sparse_member_p, sparse_fixup_header): Use tar_sparse_init(). 2005-06-23 Sergey Poznyakoff * src/sparse.c (pax_sparse_member_p): Checking member size vs. file size is not reliable enough.

Fix bugs introduced yesterday: * src/sparse.c (tar_sparse_init): Initialize dimped_size to 0. (sparse_scan_file): Initialize archive_file_size to 0. The variable keeps size of the file *as stored in the archive*, not the size reported by stat. 2005-06-22 Paul Eggert A sweep of the sparse code prompted by a bug report by Jim Meyering. * src/sparse.c: Include . (struct tar_sparse_file): offset and dumped_size are off_t, not size_t. optab is now const *. (dump_zeros): Return bool success flag, not off_t. All callers changed. Use a constant-zero buffer rather than clearing a buffer each time. Don't mess up if write fails. (dump_zeros, check_sparse_region): Don't assume off_t is no wider than size_t. (tar_sparse_init): Don't bother clearing a field that is already clear. (zero_block_p): First arg is const *, not *. (clear_block, SPARSES_INIT_COUNT): Remove. (sparse_add_map): First arg is now struct start_stat_info *, not struct tar_sparse_file *. All callers changed. Use x2nrealloc to check for size_t overflow. (parse_scan_file): Cache commonly-used parts of file. Use an auto buffer, not a static one. Don't bother clearing the buffer; not needed. Don't bother clearing items that are already clear. (oldgnu_optab, star_optab, pax_optab): Now const. (sparse_dump_region): Don't bother clearing the buffer before reading into it; just clear the parts that aren't read into. (sparse_dump_file): Clear the whole local variable 'file'. (diff_buffer): Remove; now a local var. (check_sparse_region): Don't bother clearing buffer before reading into it. Don't assume off_t is promoted to long. (oldgnu_get_sparse_info, star_get_sparse_info): Use an auto status, not static. * src/tar.h (struct tar_stat_info): had_trailing_slash is now bool, not int. * src/xheader.c (sparse_offset_coder, sparse_numbytes_coder): Rewrite to avoid cast. (sparse_offset_decoder, sparse_numbytes_decoder): Diagnose excess entries rather than crashing. 2005-06-22 Jim Meyering * src/common.h (timespec_lt): Add a return type: bool. 2005-06-21 Paul Eggert Further improvements inspired by Jim Meyering's fixes. * NEWS: Better support for full-resolution time stamps.

Add lib/xalloc-die.c, lib/obstack.c. * src/buffer.c (set_start_time, compute_duration, start_time): Use gettime rather than rolling our own code. * src/common.h (OLDGNU_NAME_FIELD_SIZE, MAXOCTAL11, MAXOCTAL7): Remove. (newer_ctime_option): Remove. (timespec_lt): New function. (OLDER_STAT_TIME): Use it. (string_to_chars): First arg is char const *, not char *. (tartime): Time arg is now struct timespec. New bool arg. All callers changed. (code_ns_fraction): New decl. (sys_stat_nanoseconds): Remove decl. (get_stat_atime, get_stat_ctime, get_stat_mtime): New functions. (set_stat_atime, set_stat_ctime, set_stat_mtime): New functions. * src/compare.c: Include utimens.h rather than rolling our own. (diff_dir, diff_file, diff_link, diff_symlink, diff_special): Prototype. (diff_dumpdir, diff_multivol): Prototype. (diff_file): Support higher-resolution time stamps. * src/create.c: Include utimens.h rather than rolling our own. (MAX_OCTAL_VAL): New macro. (tar_copy_str, string_to_chars): Don't bother to zero-fill; the destination is already zeroed. (string_to_chars): First arg is char const *. (start_private_header): Use MINOR_TO_CHARS, not MAJOR_TO_CHARS, for minor device number. (write_header_name, dump_hard_link, dump_file0): Simplify test for old GNU format. (start_header): Put in placeholders for uid, etc., even when using extended headers, for benefit of older "tar" implementations. Don't assume uintmax_t is wider than 32 bits. Output extended header for mtime if needed. (dump_regular_finish, dump_file0): Support extended time stamp resolution. * src/extract.c: Include utimens.h rather than rolling our own. (check_time): Support extended time stamp resolution. * src/list.c: Include . (tartime): Use umaxtostr rather than stringify_uintmax_t_backwards. * src/xheader.c: Include . Do not include .

(to_decimal): Remove; superseded by inttostr. All callers changed to use umaxtostr. (xheader_format_name): Don't assume pids and uintmax_t values fit in 63 bytes (!) when printed. (decode_record): Don't bother to check for ERANGE; an out of range value must be treater than len_max anyway. If the length is out of range, output it in the diagnostic. (format_uintmax): Remove; all callers changed to use umaxtostr. (xheader_print): Don't assume sizes can be printed in 99 bytes (!). (out_of_range_header): New function. (decode_time): Use it. (code_time): Accept struct timespec, not time_t and unsigned long. All callers changed. Size sbuf properly, and remove unnecessary check. Don't assume time stamps can fit in 199 bytes. Handle negative time stamps. Handle fractional time stamps more consistently. Don't output unnecessary trailing zeros. (decode_time): Yield struct timespec, not time_t and unsigned long. All callers changed. Handle negative time stamps. Truncate towards minus infinity consistently. Improve overflow checks, and output a better diagnostic on overflow. (code_num): Don't assume uintmax_t can be printed in 99 bytes (!). (decode_num): New function, for better diagnostics. (atime_coder, atime_decoder, gid_decoder, ctime_coder): (ctime_decoder, mtime_coder, mtime_decoder, size_decoder): (uid_decoder, sparse_size_decoder, sparse_numblocks_decoder): (sparse_offset_decoder, sparse_numbytes_decoder): Use decode_num, etc., instead of xstrtoumax, etc. 2005-06-21 Jim Meyering Carefully crafted invalid headers can cause buffer overrun. Invalid header fields go undiagnosed. Some valid time strings are ignored. * src/xheader.c (sparse_numblocks_decoder): Remove unchecked use of `calloc'. Use xcalloc instead. (decode_time, gid_decoder, size_decoder, uid_decoder): (sparse_size_decoder, sparse_offset_decoder, sparse_numblocks_decoder): Ensure that the result of calling xstrtoumax is no larger than the maximum value for the target type. Upon any failure, exit with a diagnostic. (sparse_numblocks_decoder): Avoid buffer overrun/heap corruption: use x2nrealloc, rather than `n *= 2' and xrealloc(p, n,.... (decode_time): Rewrite to accept time strings like 1119018481.000000000. Before, such strings were always ignored. 2005-06-13 Sergey Poznyakoff * src/create.c (dump_file0): Check for is_avoided_name() first. Fixes bug reported by Martin Lohmeier * tests/update.at: New file * tests/Makefile.am (TESTSUITE_AT): Add update.at * tests/testsuite.at: Likewise 2005-06-13 Sergey Poznyakoff * configure.ac (AC_STRUCT_ST_BLKSIZE) (AC_STRUCT_ST_BLOCKS): Removed. Handled by system.m4. 2005-06-02 Paul Eggert * src/names.c (excluded_name): excluded_filename -> excluded_file_name, because the name was changed in gnulib. 2005-05-30 Sergey Poznyakoff * src/tar.c (read_name_from_file,update_argv): Automatically detect nul-terminated list files. * NEWS: Updated 2005-05-27 Sergey Poznyakoff * scripts/backup.sh.in: Bugfixes. 2005-05-26 Sergey Poznyakoff * scripts/backup.in: Minor fixes * scripts/backup.sh.in (mt_begin,mt_rewind) (mt_offline,mt_status): Use $MT to invoke mt (init_common): Set --rsh-command option for mt if TAPE_FILE is a remote archive. * doc/tar.texi: Document new backup scripts behavior 2005-05-22 Sergey Poznyakoff * lib/.cvsignore: Updated * lib/Makefile.tmpl: Add new paxutils files * po/POTFILES.in: Likewise * src/buffer.c: Update invocations of safer_name_suffix() * src/create.c: Likewise * src/extract.c: Likewise * src/xheader.c: Likewise * src/common.h: Include paxlib.h instead of paxerror.h (safer_name_suffix,removed_prefixes_p): Removed.

Proposed by Benno Schulenberg. * src/extract.c: Likewise (extract_file): Assign orig_file_name to save_name uniformly over the program. This fixes matching directory names at the start of an archive volume. * src/buffer.c (flush_write): Warn when the name of the archive straddling volume boundary is longer than 100 characters. Earlier behavior was to issue a fatal error. (struct zip_magic): Reverted part of changes from 2005-04-04. They make the maintenance too costly. Removing `unsigned' qualifier from `magic' member should be enough. * src/compare.c (diff_init): Read directory file if in listed incremental. This prevents spurious 'Contents differ' diagnostics. (diff_archive): Minor fixes to text messages (diff_file,diff_dumpdir,diff_multivol): Assign orig_file_name to save_name uniformly over the program. This fixes matching directory names at the start of an archive volume. * src/create.c: Assign orig_file_name to save_name uniformly over the program.

Test splittind directory members between the archive volumes. * tests/Makefile.am: Add multiv04.at * tests/testsuite.at: Likewise. 2005-04-04 Paul Eggert * configure.ac (AC_CONFIG_AUX_DIR): Rename from config to build-aux, for reasons discussed in the thread beginning at . * .cvsignore: Remove config; add build-aux. * src/buffer.c (struct zip_magic): Use char arrays, not pointers. The unsigned char * pointer ran afoul of pedantic C compilers, and we didn't need pointers anyway. Put the size field before the data to avoid unnecessary padding. All uses changed. (magic) Make it const, since it doesn't change. All uses changed. 2005-04-02 Paul Eggert * src/xheader.c (decode_record): Don't dump core when given a corrupted extended header. Problem reported by Jim Meyering. Also, check for other ways that the header might be invalid, e.g., missing newline at end. Do not allow keys with nulls. Allow blanks before and after length, as POSIX requires. Do not allow leading "-" in length. Check for length overflow. (xheader_decode, xheader_decode_global): Let decode_record check for exhaustion of record. (xheader_read): Null-terminate the extended record; decode_record relies on this. 2005-03-21 Paul Eggert * bootstrap (TP_URL): Change from to to avoid some redirection glitches. Use "trap - 0" rather than "trap 0" to fix a POSIX-conformance bug. * doc/.cvsignore: Change "tar.info" to "tar.info*". Sort. * lib/.cvsignore: Add intprops.h (new gnulib file). 2005-03-04 Sergey Poznyakoff * src/list.c (print_header): Print UID/GID in case of empty user/group name. This could occur when dumping files belonging to non-existing users and when listing broken archives. Reported by Igor Lautar. * src/create.c: Correctly parse empty uname/gname * src/sparse.c (sparse_scan_file): Bugfix. offset had incorrect type. * scripts/backup.in: Use `head -n 1'. Provide missing argument to ${MT_STATUS}. Proposed by Jan Merka. * scripts/backup.sh.in: Likewise.

Fixed UTF. * src/list.c (read_header): Removed assignment to oldgnu_header.isextended. It was breaking append mode. * tests/append01.at: New test. * tests/Makefile.am: Added append01.at * tests/testsuite.at: Likewise 2005-02-06 Sergey Poznyakoff
