* 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.
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.

* 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.

(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.

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.
Make sure the files are deleted only if they were succesfully stored
to the archive.
* src/exit.c: New file.
* src/unlink.c: New file.

(fatal_exit_hook): New extern.
* src/create.c (create_archive): Call finish_deferred_unlinks.

common.h.
