2021-02-13 Sergey Poznyakoff <gray@gnu.org> Version 1.34 2021-02-08 Pavel Raiskup <praiskup@redhat.com> xattrs: fix capabilities root test Related discussion in the Fedora pull-request: https://src.fedoraproject.org/rpms/tar/pull-request/8 * tests/capabs_raw01.at: Newer systems (currently e.g. Fedora 34) print getcap output in format CAP=VAL, not CAP+VAL. 2021-02-08 Sergey Poznyakoff <gray@gnu.org> Gracefully handle duplicate symlinks when extracting If the archive being extracted contains multiple copies of the same symlink, extract only the first of them and skip the rest. The use case is described in https://lists.gnu.org/archive/html/bug-tar/2021-01/msg00026.html The bug was introduced by 2d3396c3ea. * src/extract.c (create_placeholder_file): If placeholder already exists and is registered in the delayed_link list, return immediately. 2021-02-04 Sergey Poznyakoff <gray@gnu.org> Fix savannah bug #60002 Bug was introduced by commit 34d15af1. * src/extract.c (prepare_to_extract): When extracting over pipe, process only regular files. * tests/extrac24.at: New test case. * tests/Makefile.am: Add new test case. * tests/testsuite.at: Likewise. 2021-01-17 Sergey Poznyakoff <gray@gnu.org> Fix memory leak in read_header Bug reported in https://savannah.gnu.org/bugs/?59897 * src/list.c (read_header): Don't return directly from the loop. Instead set the status and break. Return the status. Free next_long_name and next_long_link before returning. 2021-01-17 Sergey Poznyakoff <gray@gnu.org> Fix improper argument reference. (bug introduced by 1ff0b63f) * src/tar.c (parse_default_options): Pass args as is to the argp_parse. 2021-01-16 Sergey Poznyakoff <gray@gnu.org> Fix regression itroduced by 66162927. * src/misc.c (chdir_arg): Initialize the abspath field to NULL. (tar_getcdpath): Actually initialize the abspath field here. 2021-01-14 Sergey Poznyakoff <gray@gnu.org> Fixes in the delete_archive_members function * src/delete.c (delete_archive_members): Clean-up the code. Avoid entering the loop from the middle. Free the memory allocated for current_stat_info. 2021-01-08 Sergey Poznyakoff <gray@gnu.org> Use stdopen from gnulib * gnulib.modules: Request stdopen * lib/Makefile.am: Remove stdopen.c and stdopen.h * lib/stdopen.c: Remove. * lib/stdopen.h: Remove. * src/tar.c: stdopen returns 0 on success. 2021-01-08 Sergey Poznyakoff <gray@gnu.org> Actually prefer /dev/full over /dev/null as a replacement for stdin * lib/stdopen.c (stdopen): Fix improper condition. Avoid leaking extra file descriptor. * src/tar.c (main): Set name of the stdout for diagnostics. Bail out if stdopen fails. 2021-01-07 Sergey Poznyakoff <gray@gnu.org> Version 1.33 * NEWS: Update. * configure.ac: Raise version number. Require automake 1.15 and autoconf 2.64. * gnulib: pull v0.1-4333-g30820c2 * src/names.c: Use hash_remove instead of the deprecated hash_delete. 2021-01-06 Sergey Poznyakoff <gray@gnu.org> Update copyright years 2020-07-13 Sergey Poznyakoff <gray@gnu.org> Fix typo in the manpage * doc/tar.1: Fix description of the --newer option 2020-07-10 Pavel Raiskup <praiskup@redhat.com> Bugfix --sparse --diff mode Originally reported in: https://bugzilla.redhat.com/show_bug.cgi?id=1853469 * src/sparse.c (check_data_region): Only compare the part of buffer really fed by safe_read(), not whole rdsize. 2020-06-24 Sergey Poznyakoff <gray@gnu.org> Accept only position-sensitive (file-selection) options in file list files. Using such options as -f, -z, etc. is senseless in the file list file and bypasses the option consistency checks in decode_options. Therefore, only options related to file selection (a.k.a position-sensitive options) are allowed in files. * doc/tar.texi: Document changes. * src/common.h (tar_args): Move from tar.c (TAR_ARGS_INITIALIZER): New macro. * src/names.c: Declare option group identifiers as an enum.

(parse_opt): Special handling for ARGP_KEY_INIT. (argp_children): New static variable. (args): Remove static variable. (more_options): Allow only options from names_argp. (parse_default_options): Take a pointer to struct tar_args as argument. Replace the loc member during the call to argp_parse and restore it afterwards. (decode_options): Use automatic variable for args. 2020-06-22 Sergey Poznyakoff <gray@gnu.org> Fix the logic of prepare_to_extract. * src/extract.c (prepare_to_extract): Return true to proceed with the extraction, and false to skip the current member. If extracting over a pipe, skip unlinking logic. (extract_archive): Update accordingly. 2020-06-15 Sergey Poznyakoff <gray@gnu.org> Make sure link counting works for file names supplied with -T * src/common.h (name_count): Remove extern. (files_count): New enum. (filename_args): New extern. * src/names.c (name_count): Remove. (files_count): New variable. (name_add_name,name_add_file): Update filename_args. * src/create.c (create_archive): Set trivial_link_count depending on the filename_args. 2020-06-10 Alfred M. Szmidt <ams@gnu.org> Remove freemanuals.texi * doc/Makefile.am (tar_TEXINFOS): Remove freemanuals.texi. * doc/freemanuals.texi: Delete file. * doc/tar.texi (Free Software Needs Free Documentation): Remove appendix. 2020-06-03 Sergey Poznyakoff <gray@gnu.org> Fix typo in docs 2020-06-03 Sergey Poznyakoff <gray@gnu.org> Bugfix * src/sparse.c (sparse_diff_file): Fix return value. 2020-05-19 Paul Eggert <eggert@cs.ucla.edu> tar: avoid read overrun Problem reported by Timotej Kapus in: https://lists.gnu.org/r/bug-tar/2020-05/msg00001.html * src/transform.c (parse_transform_expr): Diagnose ‘--transform='s'’ instead of continuing past '\0'. 2020-02-15 Sergey Poznyakoff <gray@gnu.org> Fix handling of linked rename chains in incremental backups * src/incremen.c: Change the meaning of the DIRF_RENAMED flag. Now it marks a directory which is the last one in a chain of renames. Regular renamed directories are recognized by their orig member being non-NULL. Directories marked with DIRF_RENAMED start encoding of renames. (procdir): Clear DIRF_RENAMED flag on directories which are origins for renames. (makedumpdir): Use the orig member to check if the directory is a result of a rename. (store_rename): Move the check for DIR_IS_RENAMED to the caller. Don't clear the DIRF_RENAMED, it is not needed any more. * tests/rename06.at: New test. * tests/Makefile.am: Add rename06.at * tests/testsuite.at: Likewise. 2020-02-08 Sergey Poznyakoff <gray@gnu.org> Update copyright years 2020-02-08 Sergey Poznyakoff <gray@gnu.org> Fix the --no-overwrite-dir option Given this option, tar failed to preserve permissions of empty directories and to create files under directories owned by the current user that did not have the S_IWUSR bit set. * src/extract.c (fd_chmod): Rename to fd_i_chmod. (fd_chmod): New function. (safe_dir_mode): New function. (extract_dir): Special handling for existing directories in --no-overwrite-dir mode. * tests/extrac23.at: New file. * tests/Makefile.am: Add new test case. * tests/testsuite.at: Likewise. 2019-12-03 Sergey Poznyakoff <gray@gnu.org> Wildcards in exclude-vcs-ignore mode should not match slash * src/exclist.c (info_attach_exclist): Use the FNM_FILE_NAME flag. 2019-11-27 Sergey Poznyakoff <gray@gnu.org> Version 1.32.90 2019-11-25 Sergey Poznyakoff <gray@gnu.org> Testsuite fixes * tests/sparse06.at: Skip the test if genfile is unable to create sparse files. * tests/sptrcreat.at: Likewise. * tests/sptrdiff00.at: Likewise. * tests/sptrdiff01.at: Likewise. 2019-11-14 Sergey Poznyakoff <gray@gnu.org> Another testsuite fix. * tests/extrac11.at: Skip test if ulimit fails. 2019-11-13 Sergey Poznyakoff <gray@gnu.org> Testsuite fix. * tests/remfiles10.at: Don't expect EINVAL when trying to remove CWD. 2019-08-25 Sergey Poznyakoff <gray@gnu.org> Consistently use x2realloc for buffer reallocation * src/create.c (create_archive): Use x2realloc * src/names.c (copy_name) (add_hierarchy_to_namelist): Use x2realloc 2019-08-18 Sergey Poznyakoff <gray@gnu.org> Fix extraction of symbolic links hardlinked to another symbolic links * src/extract.c (create_placeholder_file): Take additional argument: the delayed_link entry after which to the newly created one. (extract_link): Create a placeholder file if the target link name exists in the delayed_link list. 2019-04-11 Sergey Poznyakoff <gray@gnu.org> Fix --delay-directory-restore on archives with reversed member ordering. * src/extract.c (find_direct_ancestor): Remove useless test. (delay_set_stat): If the file name being added is already in the list, update stored data instead of creating a new entry. This works for archives with reversed order of members. * tests/extrac22.at: New testcase. * tests/Makefile.am: Add new testcase. * tests/testsuite.at: Include new testcase. 2019-03-28 Sergey Poznyakoff <gray@gnu.org> Minor change * scripts/backup.in: Fix typo Typesetting fixes in the manpage 2019-03-28 Zachary Vance <za3k@za3k.com> POSIX extended format headers do not include PID by default The intent is to make binary-equivalent PAX archives easy to create. If POSIXLY_CORRECT is set, the POSIX standard default is used, which embeds the pid. * src/common.h (posixly_correct): New global. * src/tar.c (decode_options): Detect the POSIXLY_CORRECT environment variable. * src/buffer.c (add_chunk_header): Change filenames of multipart files to omit the pid. * src/xheader.c (HEADER_TEMPLATE): New macro. (xheader_xhdr_name, xheader_ghdr_name): Use HEADER_TEMPLATE to select the template for the POSIX extended header name. * doc/tar.texi: Document the change. 2019-03-03 Sergey Poznyakoff <gray@gnu.org> Check return value from xgetcwd * src/misc.c (chdir_arg,tar_getcdpath): Check for non-NULL return from xgetcwd. The function returns NULL for any error originating from getcwd. 2019-02-23 Sergey Poznyakoff <gray@gnu.org> Version 1.32 2019-02-04 Sergey Poznyakoff <gray@gnu.org> Minor fixes in docs. * doc/tar.1: Remove description of the --preserve option Document verbosity levels. * doc/tar.texi: Fix description of the -o option. 2019-01-15 Daniel Le <greenrecyclebin@gmail.com> Fix typos in the documentation Short option "t" was mistranslated to "--test" instead of "--list" in commit 67cad0792b4e6cf22c6cb1b167b149cd176d49f9. 2019-01-15 Sergey Poznyakoff <gray@gnu.org> Fix build on AIX * src/unlink.c (flush_deferred_unlinks): Avoid possible duplicate case (if ENOTEMPTY==EEXIST) 2019-01-15 Sergey Poznyakoff <gray@gnu.org> Version 1.31.90 2019-01-14 Sergey Poznyakoff <gray@gnu.org> Ensure gnu format when running checkpoint tests 2019-01-14 Sergey Poznyakoff <gray@gnu.org> Fix compression tests Existing compression tests used tar with compiled-in defaults. However, some of the defaults are sure to create archives that are not byte-to-byte reproducible (e.g. DEFAULT_ARCHIVE_FORMAT=POSIX, because the name field in posix extended headers uses PID of the creating process by default). Moreover, some compressors (e.g. gzip) store current timestamp in the file header when compressing from stdin, so that using cmp on the two created archives as the tests did is error-prone. Another problem is that the tests implicitly assumed that tar uses archive suffix to recognize its format when extracting, which isn't the case. Finally, there's hardly any reason in using sed to create m4 sources, when everything can be achieved by m4 itself. * tests/Makefile.am: Remove generation of compress-*.at files. * tests/compress.at.in: Remove. * tests/compress.m4: New file. * tests/testsuite.at: Include compress.m4, use TAR_CHECK_COMPRESS to check compression options. 2019-01-14 Sergey Poznyakoff <gray@gnu.org> Fix possible NULL dereference (savannah bug #55369) * src/sparse.c (pax_decode_header): Check return from find_next_block. 2019-01-14 Sergey Poznyakoff <gray@gnu.org> Fix compilation without iconv. 2019-01-14 Sergey Poznyakoff <gray@gnu.org> Fix iconv usage. Patch by Christian Weisgerber. * src/utf8.c (utf8_convert): non-zero return from iconv means failure. 2019-01-14 Pavel Raiskup <praiskup@redhat.com> tests: fix numeric.at for BSD While creating file, BSD kernels inherit the group ownership from parent directory. http://lists.gnu.org/archive/html/bug-tar/2016-06/msg00000.html * tests/numeric.at: Attempt to 'chown' the newly created directory to proper group (at least on affected machines that command is expected to succeed). 2019-01-14 Sergey Poznyakoff <gray@gnu.org> Fix typo in manpage. 2019-01-14 Sergey Poznyakoff <gray@gnu.org> Fix expected output in dirrem tests. In both tests, the "file changed as we read it" warning might be produced for dir/sub, depending on the ctime resolution and timing. The problem was fixed by 64b43fdf70d82c39eb2ca900cd4f8e49, but regressed after e7cd377f7801d42aa8e07addff93d2150666c237, which removed 1 second delays between each pair of checkpoints. Since the presense or absense of this warning is irrelevant for the test, it is now suppressed. * tests/dirrem01.at: Suppress the file-changed warning. * tests/dirrem02.at: Likewise. 2019-01-12 Sergey Poznyakoff <gray@gnu.org.ua> Fix the use of --checkpoint without explicit --checkpoint-action * src/checkpoint.c (checkpoint_finish_compile): Set default action, if necessary. * tests/checkpoint/defaults.at: New testcase. * tests/checkpoint/dot-compat.at: New testcase. * tests/checkpoint/dot-int.at: New testcase. * tests/checkpoint/dot.at: New testcase. * tests/checkpoint/interval.at: New testcase. * tests/Makefile.am: Add new testcases. * tests/testsuite.at Include new testcases. 2019-01-10 Sergey Poznyakoff <gray@gnu.org.ua> Remove erroneous abort() call The call was introduced by commit ccef8581. It caused tar to abort on perfectly normal operations, like untarring archives containing ./ with the -U option, See http://lists.gnu.org/archive/html/bug-tar/2019-01/msg00019.html for details. * src/extract.c (maybe_recoverable): Remove misplaced call to abort(). 2019-01-02 Sergey Poznyakoff <gray@gnu.org> Version 1.31 2018-12-28 Sergey Poznyakoff <gray@gnu.org> Fix the difflink test Hardlinking a symlink produces hardlink on BSD and symlink on GNU/Linux. Avoid the ambiguity. * tests/difflink.at: Create hard link from a regular file. 2018-12-28 Sergey Poznyakoff <gray@gnu.org> Work over a bug in gnulib error() The error() function from glibc correctly prefixes each message it prints with program_name as set by set_program_name. However, its replacement from gnulib, which is linked in on systems where this function is not available, prints the name returned by getprogname() instead. Due to this messages output by tar subprocess (which sets its program name to 'tar (child)') become indiscernible from those printed by the main process. In particular, this breaks the remfiles01.at and remfiles02.at test cases. * configure.ac: Define ENABLE_ERROR_PRINT_PROGNAME if using gnulib error(). * src/tar.c [ENABLE_ERROR_PRINT_PROGNAME] (tar_print_progname): New function. (main) [ENABLE_ERROR_PRINT_PROGNAME]: Set error_print_progname. 2018-12-28 Sergey Poznyakoff <gray@gnu.org> Implement the "wait" checkpoint action. This action instructs tar to pause until given signal is delivered. The newer genfile tool uses this action for communication between genfile and tar in exec mode. This eliminates race conitions and speeds up the tests based on exec mode. * doc/tar.texi: Document changes. * paxutils: Upgrade. * src/checkpoint.c: Implement the wait action. * src/common.h (decode_signal): New proto. * src/tar.c (decode_signal): New function. (set_stat_signal): Rewrite. * tests/dirrem01.at: Adjust genfile and tar command line arguments to use the new feature. * tests/dirrem02.at: Likewise. * tests/filerem01.at: Likewise. * tests/filerem02.at: Likewise. * tests/grow.at: Likewise. * tests/sptrcreat.at: Likewise. * tests/sptrdiff00.at: Likewise. * tests/sptrdiff01.at: Likewise. * tests/truncate.at: Likewise. 2018-12-27 Sergey Poznyakoff <gray@gnu.org> Fix CVE-2018-20482 * NEWS: Update. * src/sparse.c (sparse_dump_region): Handle short read condition. (sparse_extract_region,check_data_region): Fix dumped_size calculation. Handle short read condition. (pax_decode_header): Fix dumped_size calculation. * tests/Makefile.am: Add new testcases. * tests/testsuite.at: Likewise. * tests/sptrcreat.at: New file. * tests/sptrdiff00.at: New file. * tests/sptrdiff01.at: New file. 2018-12-21 Sergey Poznyakoff <gray@gnu.org> Disallow modifications to the global pax extended header in update mode. Updating global headers in update mode is not possible, because: 1) If the original archive was not in PAX format, writing the global header would overwrite first member header (and eventually data blocks) in the archive. 2) Otherwise, using the --pax-option can make the updated header occupy more blocks than the original one, which would lead to the same effect as in 1. This also fixes http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00007.html * src/xheader.c (xheader_forbid_global): New function. * src/common.h (xheader_forbid_global): New prototype. * src/update.c (update_archive): Use xheader_forbid_global, instead of trying to write global extended header record. 2018-12-21 Sergey Poznyakoff <gray@gnu.org> Bugfix Bug reported in http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00014.html * src/names.c (collect_and_sort_names): Fix iteration over namelist. 2018-12-21 Sergey Poznyakoff <gray@gnu.org> Fix semantics of -K used together with explicit member names. This also fixes the bug reported in http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00012.html * src/common.h (starting_file_option): Describe the variable. * src/names.c (add_starting_file): New function. (name_match): Ignore everything before the member indicated by the --starting-file option * src/tar.c: Use add_starting_file to handle the -K option. 2018-12-21 Sergey Poznyakoff <gray@gnu.org> Fix error handling when reading incremental snapshots Bug reported in http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00008.html * incremen.c (read_incr_db_01): Don't try to continue after errors. 2018-12-21 Sergey Poznyakoff <gray@gnu.org> Reject pax options starting with equals sign Bug reported in http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00010.html * xheader.c (xheader_set_keyword_equal): Bail out if the keyword starts with = 2018-12-21 Sergey Poznyakoff <gray@gnu.org> Fix buffer overflow Bug reported in http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00011.html * src/xheader.c (xheader_format_name): fix length calculation 2018-12-21 Sergey Poznyakoff <gray@gnu.org> Fix improper memory access Bug reported in http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00009.html * src/transform.c (parse_transform_expr): Check if re is not empty before accessing its last byte. 2018-11-24 Sergey Poznyakoff <gray@gnu.org> Fix parsing of ACLs Text returned by acl_to_text can contain comments (introduced by #). Strip comments and horizontal tabs prior to storing ACLs in PAX headers. * src/xattrs.c (xattrs_acls_cleanup): New function. (xattrs__acls_get_a,xattrs__acls_get_d): Use xattrs_acls_cleanup. 2018-11-24 Sergey Poznyakoff <gray@gnu.org> Don't try to read past the end of header string fields * src/common.h (assign_string_n): New proto. (ASSIGN_STRING_N): New macro. * src/misc.c (assign_string_n): New function. * gnulib.modules: Add strnlen. * src/buffer.c: Use assign_string_n where appropriate. * src/list.c: Likewise. 2018-11-12 Sergey Poznyakoff <gray@gnu.org> Fix verbose ACL listing * src/xattrs.c (acls_one_line): Advance pos. (xattrs_print): Insert a comma between ACL and default ACL if both are non-empty. 2018-10-29 Paul Eggert <eggert@cs.ucla.edu> tar: fix numbered backup bug * src/misc.c (maybe_backup_file): Pass chdir_fd, not AT_FDCWD, to find_backup_file_name. This fixes a bug whereby the wrong backup file name was chosen for numbered backups. 2018-10-29 Paul Eggert <eggert@cs.ucla.edu> * src/tar.c (expand_pax_option): Pacify recent GCC. 2018-10-29 Paul Eggert <eggert@cs.ucla.edu> build: update gnulib submodule to latest * src/misc.c (maybe_backup_file): Adjust to Gnulib change. 2018-08-02 Sergey Poznyakoff <gray@gnu.org> Minor fixes in wordsplit.c 2018-08-02 Paul Eggert <eggert@cs.ucla.edu> build: update gnulib submodule to latest 2018-07-31 Sergey Poznyakoff <gray@gnu.org> Silence gcc warnings in wordsplit 2018-07-31 Sergey Poznyakoff <gray@gnu.org> Fix double-free introduced by 577dc345 * src/utf8.c (utf8_convert): Don't store freed value in *output 2018-07-31 Pavel Raiskup <praiskup@redhat.com> Report race on systems without O_DIRECTORY * src/names.c (collect_and_sort_names): Report ENOTDIR after successful fstat() but !S_ISDIR. 2018-07-31 Pavel Raiskup <praiskup@redhat.com> Avoid some resource leaks * src/incremen.c (store_rename): Free temp_name, leaked before for each renamed directory with --listed-incremental. * src/transform.c (add_literal_segment): Tighten arguments by const. (parse_transform_expr): Free 'str', leaked storage for each --transform option before. * src/utf8.c (utf8_convert): Deallocate buffer for failed iconv() call so callers don't have to. 2018-07-31 Sergey Poznyakoff <gray@gnu.org> Sync wordsplit and paxutils with the most recent versions 2018-06-14 Paul Eggert <eggert@cs.ucla.edu> * doc/tar.1: Fix font typo noted by esr. 2018-05-16 Paul Eggert <eggert@cs.ucla.edu> * doc/tar.1: Don't refer to nonexistent tar(5). 2018-04-13 Jim Meyering <meyering@fb.com> --one-top-level: avoid a heap-buffer-overflow * NEWS: Mention this. * src/suffix.c (strip_compression_suffix): Fix string comparison guard.

But sometimes, the genfile was fast enough to win the race and unlinked the directory before the member was written into the archive (IOW, the order was 1-2-3-6-4-5). This led to the occasional warning 'tar: dir/sub: file changed as we read it'. Swap the order of 'sleep=1' and 'echo' actions so the genfile utility has (hopefully) enough time to do the unlink before writing the file into the archive (enforce 1-2-3-6-4-5 order). * tests/dirrem01.at: Swap 'sleep=1' and 'echo' actions. * tests/dirrem02.at: Likewise. 2018-03-13 Sergey Poznyakoff <gray@gnu.org> Fix typos in the docs 2018-03-13 Sergey Poznyakoff <gray@gnu.org.ua> Provide a way to skip tests that create very large files Define environment variable TARTEST_SKIP_LARGE_FILES=1 in order to skip tests that require lots of disk space. * tests/testsuite.at (AT_SKIP_LARGE_FILES): New macro. * tests/sparse03.at: Mark test with AT_SKIP_LARGE_FILES. * tests/sparse05.at: Likewise. * tests/star/pax-big-10g.at: Likewise. * tests/star/ustar-big-2g.at: Likewise. * tests/star/ustar-big-8g.at: Likewise. 2018-03-13 Sergey Poznyakoff <gray@gnu.org.ua> Testsuite bugfix * tests/difflink.at: Define order of files within tested archive. 2018-03-13 Sergey Poznyakoff <gray@gnu.org> testsuite: account for absolute file names starting with double slash * tests/incr08.at: Absolute file names can start with // * tests/xform03.at: Likewise. 2017-12-17 Sergey Poznyakoff <gray@gnu.org> Version 1.30 * configure.ac: Set version 1.30 * NEWS: Update. 2017-11-20 Paul Eggert <eggert@cs.ucla.edu> Fix "concatenating" typo.

When creating multivolume archives, the bufmap code in buffer.c implicitly assumed that the members are stored in the archive contiguously, ignoring the member (and eventual extended) headers between them. This worked until the member header happened to be at the very beginning of the volume, in which case its length was included in the calculation of the stored size and size left to store. Due to this, the GNUFileParts extended header contained invalid GNU.volume.offset value, and the resulting archive failed to extract properly. This patch also eliminates improper listing of file part headers as regular files, when creating multivolume posix archives with -v. * src/buffer.c (bufmap): New member nblocks. Counts number of blocks of file data written since reset. (bufmap_reset): Reset nblocks to 0. (_flush_write): Update nblocks.

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.

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.

Use SEEK_HOLE/SEEK_DATA feature of lseek on systems that support it. This can make archiving of sparse files much faster. Implement the --hole-detection option to allow users to select hole-detection method. * src/common.h (hole_detection_method): New enum. (hole_detection): New global. * src/sparse.c (sparse_scan_file_wholesparse): New function as a method for detecting sparse files without any data. (sparse_scan_file_raw): Rename from sparse_scan_file; with edits. (sparse_scan_file_seek): New function.

(flush_deferred_unlinks): Skip cwds and nonempty directories at the first pass. If force is requested, run a second pass removing them. (queue_deferred_unlink): Make sure current working directory entries are sorted in descending order by the value of dir_idx. This makes sure they will be removed in right order, which works around unlinkat bug on FreeBSD and GNU/Hurd. * tests/remfiles08b.at: Remove expected failure. * tests/remfiles09b.at: Likewise. 2015-11-10 Sergey Poznyakoff <gray@gnu.org> Fix coredump on FreeBSD when TAR_OPTIONS is set * src/tar.c (parse_default_options): Use program_name instead of program_invocation_short_name.

(dump_file0): Use areadlinkat_with_size, rather than trying to do it by hand, incorrectly. This also avoids assumption that the symlink contents fit on the stack. Also, use the transformed link name, not the original link name, when deciding whether the name is long enough to require writing a long link. 2015-07-13 Paul Eggert <eggert@cs.ucla.edu> tar: port -d to longer symlinks * src/compare.c (diff_symlink): Don't use alloca on symlink length; it might be too big for the stack. Don't assume that readlinkat's return value fits in 'int'. Prefer memcmp to strncmp where either will do. 2015-07-13 Paul Eggert <eggert@cs.ucla.edu> tar: port to recent gnulib * gnulib.modules: Remove 'acl' and add 'file-has-acl'. 2015-07-13 Paul Eggert <eggert@cs.ucla.edu> tar: pacify GCC 5.1 -Wformat-signedness * lib/wordsplit.c (struct wordsplit_node.flags): Now unsigned, so that 'printf ("%x", p->flags)' doesn't provoke GCC. * src/incremen.c (read_num, dumpdir_ok): Don't printf an int with %x or %o. 2015-04-16 Sergey Poznyakoff <gray@gnu.org.ua> Fix extraction from concatenated incremental archives. * src/common.h (remove_delayed_set_stat): New proto. * src/extract.c (free_delayed_set_stat) (remove_delayed_set_stat): New function.
