conditioning tests on HAVE_ZLIB, etc, just ask libarchive for the
service and handle the failure coming back from libarchive. This
gives us better test coverage of common client usage where clients
simply try to use libarchive services and handle the errors coming
back instead of trying to second-guess which libarchive services are
compiled in.
Support Joliet extensions. This currently ignores Rockridge extensions
if both exist on the same disk unless the '!joliet' option is provided.
e.g.: tar -xvf example.iso --options '!joliet'

as the compression name when no other read filter bid. Add some
assertions to various tests to verify that read filters are properly
setting the textual name as well as the compression code.
Restoring POSIX.1e Extended Attributes on FreeBSD, part 1
This implements the basic ability to restore extended attributes
on FreeBSD, including a test suite.
from libarchive.googlecode.com: Add a new "archive_read_disk" API
that provides the important service of reading metadata from the
disk. In particular, this will make it possible to remove all
knowledge of extended attributes, ACLs, etc, from clients such
as bsdtar and bsdcpio.
Closely related, this API also provides pluggable uid->uname
and gid->gname lookup and caching services similar to
the uname->uid and gname->gid services provided by archive_write_disk.
Remember this is also required for correct ACL management.
Documentation is still pending...
into the debugger on test setup failures (otherwise, the console window
just goes away and you can't see what went wrong). On all platforms,
clean up a stray buffer before exiting.
This is the last phase of the "big decompression refactor" that
puts a lazy reblocking layer between each pair of read filters.
I've also changed the terminology for this area---the two kinds
of objects are now called "read filters" and "read filter bidders"---and
moved ownership of these objects to the archive_read core.
This greatly simplifies implementing new read filters, which
can now use peek/consume I/O semantics both for bidding (arbitrary
look-ahead!) and for reading streams (look-ahead simplifies handling
concatenated streams, for instance).
The first merge here is the overhaul proper; the remainder are small
fixes to correct errors in the initial implementation.
locale-based failures on systems where the "C" locale is so permissive
that it cannot possibly fail. In particular, this fixes a test
problem on Cygwin.
In archive_write_disk: If archive_write_header() fails to create
the file, that's a failure and should return ARCHIVE_FAILED.
Metadata restore failures still return ARCHIVE_WARN, because
that's non-critical. Fix test_write_disk_secure test to
verify the correct return code in one case; add test_write_disk_failures
to do another very simple test of restore failure.
This should fix cpio coredumping when it tries to restore to
a write-protected directory.

* support for bzip2 file with multiple concatenated bzip2 streams
* support for bzip2 file with junk after bzip2 stream
* support for gzip file with junk after gzip stream
* "fuzz" tester randomly modifies a bunch of input files in order to try
to crash libarchive (this found an amusing hang in the ISO9660 code
when trying to read images that advertised a zero blocksize).
This test is implemented, but commented out for now:
* support for gzip file with multiple concatenated gzip streams
If it's not a regular file, don't return any data, even if the size is unknown.
Update the Zip test with a hand-tweaked Zip archive that has a
directory (with length-at-end set), a regular file without
length-at-end set, and a regular file with length-at-end set and a bad
CRC. Update the test code to verify that the file size is unset
for the regular file with length-at-end.

logic here gets a little complex, but the net effect is that the
SECURE_SYMLINKS flag will prevent us from ever following a symlink.
Without it, we'll only follow symlinks to dirs. bsdtar specifies
SECURE_SYMLINKS by default, suppresses it for -P.
I've also beefed up the write_disk_secure test to verify this
behavior.

unspecified size are "unlimited" (required by Zip reader, which
sometimes does not know the uncompressed size of an entry until it
gets to the end). Also, hardlinks with unspecified (or zero) size do
not overwrite the data on disk nor do they set metadata. This is
compatible with GNU tar and NetBSD pax behavior.
