Not an issue for FreeBSD, since the base system has the necessary libraries.
Since all decompressors are always available now, we can unconditionally
enable them in archive_read_support_compression_all().
Since FreeBSD doesn't have liblzma in the base system, the
read side will always fall back to the unxz/unlzma commands for now.
(Which will in turn fail if those commands are not currently
installed.) The write side does not yet have a fallback, so
that will just fail.
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.
r751: Change __archive_strncat() to use a void * source, which reduces
the amount of casting needed to use this with "char", "signed char"
and "unsigned char".
r752: Use additions instead of multiplications when growing buffer;
faster and less chance of overflow.
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.
Refactor the read_compression_program to add two new abilities:
* Public API: You can now include a signature string when you
register a program; the program will run only on input that
matches the signature string.
* Internal API: You can use the init() function to instantiate
an external program as part of a filter pipeline. This
can be used for graceful fallback (if zlib is unavailable, use
external gzip instead) and to use external programs with
bidders that are more sophisticated than a static signature check.
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.
