on iso9660 images were returned. While I'm poking around, update
some comments around this area to try to clarify what's going on and
what still remains to be improved.
read_support_format_raw() allows people to exploit libarchive's
automatic decompression support by simply stubbing out the
archive format handler.
The raw handler is not enabled by support_format_all(), of course.
It bids 1 on any non-empty input and always returns a single
entry named "data" with no properties set.
Fix reading big-endian binary cpio archives, and add a test.
While I'm here, add a note about Solaris ACL extension for cpio,
which should be relatively straightforward to support.
Thanks to: Edward Napierala, who sent me a big-endian cpio archive
from a Solaris system he's been playing with.
Pointy hat: me
Make test_fuzz a bit more sensitive by actually reading the body
of each entry instead of skipping it.
While I'm here, move the "UnsupportedCompress" macro into the
only file that still uses it.
* Fix parsing of POSIX.1e ACLs from Solaris tar archives
* Test the above
* Preserve the order of POSIX.1e ACL entries
* Update tests whose results depended on the order of ACL entries
* Identify NFSv4 ACLs in Solaris tar archives and warn that
they're not yet supported. (In particular, don't try to parse
them as POSIX.1e ACLs.)
Thanks to: Edward Napierala sent me some Solaris 10 tar archives to test
access to the file data (if the file exists on
disk). This was broken for the first regular
file; fix it and add a test so it won't break again.
In particular, this fixes the following idiom for creating
a tar archive in which every file is owned by root:
tar cf - --format=mtree . \
| sed -e 's/uname=[a-z]*/uname=root/' -e 's/uid=[0-9]*/uid=0/' \
| tar cf - @-
fixes to read_support_compression_program. In particular, failure of
the external program is detected a lot earlier, which gives much more
reasonable error handling.
corrections to the Windows support to reconcile differences
between Visual Studio and Cygwin. Includes parts of
revisions 757, 774, 787, 815, 817, 819, 820, 844, and 886.
Of particular note, r886 overhauled the UTF-8/Unicode conversions to
work correctly regardless of whether the local system uses 16-bit
or 32-bit wchar_t. (I assume that systems with 16-bit wchar_t
use UTF-16 and those with 32-bit wchar_t use UCS-4.) This revision
also added a preference for wcrtomb() (which is thread-safe) on
platforms that support it.
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'
Thanks to: Andreas Henriksson
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.

MFC after: 30 days
* 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
