* 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.
* 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.
* 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 // != /.
* 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.
* 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.
* 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.
* src/extract.c (create_placeholder_file)
(extract_link, extract_symlink)
(extract_node, extract_fifo): Handle all possible
return values from maybe_recoverable. This complements
8f390db92f. Reported by Ico Doornekamp <bug-tar@zevv.nl>.
* NEWS: Update.
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 <akozlov@nada.kth.se>, 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.

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.
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. Use byte offset instead.
(dump_file0): Close fd before returning without
dumping the directory.
* src/buffer.c (seek_archive): Rewrite size computation
to prevent it from reaching negative values. Based on
report by Denis Excoffier <Denis.Excoffier@free.fr>.
* src/system.c (stat_to_env): Pass information about the current
volume in variables TAR_ARCHIVE, TAR_VOLUME, TAR_BLOCKING_FACTOR,
TAR_FORMAT.

* NEWS: Likewise.
* configure.ac: Version number 1.22.91.
* src/common.h (read_header_mode): New enum.
(read_header): Change type of the 3rd argument.
* src/list.c (read_header): Change type of the 3rd argument.
All callers updated.
* src/buffer.c (try_new_volume): Allow for volumes split at the
extended/ustar header boundary. This is against POSIX specs, but
we must be able to read such archives anyway.
* tests/multiv07.at: New test case.
* tests/Makefile.am: Add multiv07.at
* tests/testsuite.at: Likewise.
* src/compare.c: Update calls to read_header.

(VOLUME_TEXT, VOLUME_TEXT_LEN): New macros
(drop_volume_label_suffix): New function.
(check_label_pattern): Use drop_volume_label_suffix.

(test_label_option): Remove.
(drop_volume_label_suffix): New proto.
(test_archive_label): New proto.
* src/names.c (all_names_found): Remove test for test_label_option.
* src/tar.c (subcommand_string): Handle TEST_LABEL_SUBCOMMAND.
(set_subcommand_option): Improve diagnostics.
(parse_opt): Set subcommand if --test-label is given.
(main): Handle TEST_LABEL_SUBCOMMAND.
* src/buffer.c (match_volume_label): Call set_volume_label.
(check_label_pattern): Get label string
as argument.
(match_volume_label): Handle volume labels stored in
global PAX headers.
* src/common.c (print_header,read_header): Change signature.
(read_header_primitive): Remove prototype.
* src/list.c (recent_global_header): New static.
(list_archive): Always print volume labels.
(read_header_primitive): Remove.
(read_header): Change the signature (all callers updated)
Save the recent global header.
(volume_label_printed): New static.
(simple_print_header): New function (ex-print_header).
(print_header): Change the signature (all callers updated).
For POSIX formats, print first volume header (if set).
* src/xheader.c (xheader_write_global): Write the data
accumulated in xhdr->stk even if keyword_global_override_list
is empty.
(xheader_read): On unexpected EOF, report error instead of
coredumping.
(XHDR_PROTECTED, XHDR_GLOBAL): New defines.
(struct xhdr_tab): Remove `protected' with `flags'. All uses updated.
(decg): If XHDR_GLOBAL bit is set, call the keyword's decode
method instead of adding it to `kwl'.
* src/compare.c: Update calls to read_header.
* src/create.c: Likewise.
* src/delete.c: Likewise.
* src/update.c: Likewise.
* src/extract.c: Likewise.
(extract_volhdr): Do not print "Reading <label>" statement, because
it is inconsistent: it is not printed if the volume begins with a
member continued from the previous volume.
* tests/label01.at: New testcase.
* tests/label02.at: New testcase.
* tests/Makefile.am, tests/testsuite.at: Add new testcases.
* src/common.h (namebuf_t): New typedef.
(namebuf_create, namebuf_free)
(namebuf_name): New prototypes.
(remname): New prototype.
* src/misc.c (struct namebuf): New structure.
(namebuf_create, namebuf_free)
(namebuf_name): New functions.

checks. This is taken care of in update_archive.
* src/incremen.c (scan_directory): Use namebuf
to produce full file names.

indirection. All uses updated.
(avoided_name_table, add_avoided_name)
(is_avoided_name): Remove.
* src/update.c (update_archive): Change algorithm.
Instead of adding unmodified files to the avoided_name
table, create namelist so that it contains only
modified files.
* tests/Makefile.am: Add update01.at, update02.at
* tests/testsuite.at: Likewise.
* tests/update.at (AT_KEYWORDS): Add update00.
