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.

* NEWS: Likewise.
* configure.ac: Version number 1.22.91.
* src/tar.c (struct textual_date): ts is a copy of the structure,
not a pointer to it. Date is a copy as well, hence the `const' is
taken away.
(get_date_or_file): Return 0/1 depending on success/failure.
Copy timestamp to the `ts' member. Store a copy of the string
in `date'.
(report_textual_dates): Report only if verbose_option is set,
but always free the list.
(expand_pax_option): New function.
(parse_opt): Preprocess the argument to xheader_set_option with
expand_pax_option.
(decode_options): Call report_textual_dates unconditionally.

(xheader_write): Override `t' argument if a corresponding
exthdr.mtime or globexthdr.mtime option is set.
* NEWS: Update
* doc/tar.texi: Document the changes.
* src/buffer.c (guess_seekable_archive): New function.
(_open_archive): Call guess_seekable_archive for archives
open for reading.
(new_volume): Likewise.
* src/common.h (seek_option): New global.
* src/tar.c (options): New option --no-seek.
(parse_opt): --seek and --no-seek set seek_option,
not seekable_archive.
(decode_options): Initialize seek_option to -1.
* NEWS: Update.
* doc/tar.texi: Update.
Changes to src/create.c and src/incremen.c are partially
based on patch from Alexander Peslyak <solar at openwall.com>.
The new testcases require paxutils commit f653a2b or later.

(file_removed_diag, dir_removed_diag): New prototypes.
(addname): New argument `cmdline'.
(name_from_list): Change return value.
* src/create.c (dump_dir0, dump_dir): top_level is bool.
(create_archive): Update calls to name_from_list.
Take advantage of the name->cmdline to set top_level argument
during incremental backups.
(dump_file0): top_level is bool.
Do not bail out if a no-top-level file disappears during incremental
backup, use file_removed_diag instead.
(dump_filed): top_level is bool.
* src/incremen.c (update_parent_directory): Silently ignore
ENOENT. It should have already been reported elsewhere.
(scan_directory): Use dir_removed_diag to report missing directories.

* NEWS: Update.
* doc/tar.texi: Minor fix.
* NEWS, THANKS: Update
* src/extract.c (extract_dir): reset status to 0 if the
directory already exists.
* src/misc.c (maybe_backup_file): Assign before_backup_name
and clear after_backup_name before checking if we really need
to backup the file.
* tests/backup01.at: New testcase.
* tests/extrac08.at: New testcase.
* tests/Makefile.am, tests/testsuite.at: Add extrac08.at and
backup01.at
* Makefile.am (INCLUDES): Add ../lib, for rmt-command.h
* src/buffer.c (short_read): Report the actual record size
only if the archive descriptor refers to a device.
* tests/pipe.at, tests/shortrec.at,
tests/sparsemvp.at: Reflect the above change.
* NEWS, configure.ac: Version 1.22.90
* src/buffer.c, src/suffix.c: Add support for xz compression.

transform_member_name. It is done in read_header.
* src/list.c (decode_xform): Reflect change in data type of 2nd
argument.

(decode_header): Transform file name and link target names.
* src/tar.c: Remove --transform-symlinks.
* src/transform.c (struct transform): New member `flags'.

set global flags using `flags=' syntax.
(_transform_name_to_obstack, transform_name_fp)
(transform_name): Take an additional argument, specifying scope
flags.
which was always false on a first record and thus disabled record
size autodetection. Thanks Ed Leaver for the patch.
(_gnu_flush_read): Handle blocking_factor == 1.
* tests/sparsemv.at: Reflect changes to buffer.c.
* tests/sparsemvp.at: Likewise.
* tests/volsize.at: Likewise.
* NEWS: Update.
* THANKS: Add Ed Leaver.
* src/create.c (dump_file0): Transform symlink targets only if
explicitly required. Thanks Cyril Strejc for reporting the
problem.

New short option -J (alias for --lzma).
* src/buffer.c (try_new_volume): Print more information with error
diagnostics.
(_gnu_flush_write): Improve error checking. Adjust
real_s_sizeleft before calling new_volume to avoid creating
malformed multivolume headers.
* tests/delete05.at, tests/gzip.at, tests/ignfail.at,
tests/longv7.at, tests/lustar01.at, tests/lustar02.at,
tests/shortfile.at: Update to match new diagnostic wording
(see 2008-05-06).
