Just FYI (http://people.freebsd.org/~kientzle/libarchive/) :

"Nov 9, 2008: libarchive 2.6 should be ready for release in a couple
of weeks. It includes the usual bevy of bug fixes and a couple of new
features: a new mtree writer, new lzma decompression support, and long
option support on all platforms for both bsdtar and bsdcpio. 2.5.900
and later are pre-release test versions; please try them out and let
me know about any issues you find. "

lzma decompression support looks cool, I wonder how it was
implemented, since I heard before that lzma-utils could not be used
because of its GPL licence. And if it's an implementation from
scratch, I wonder how well it works (and how fast).
I also wonder if the zip support has improved. There were some
problems with some zip archives, I will have to try that again.

LZMA is now LGPL, so linking against it is OK wrt libarchive's BSD
license. So it isn't implemented at all in libarchive, only linked to
and treated just like gzip and bz2 currently are.

It would definitely be interested to do a "version 2.0" of the archive
tests like I did before with bzip2 and gzip.

I hope it has improved as well, although the number of problematic
files has been very small which is nice.

If you compile a package of this prerelease, I would be happy to try
it out on my system.

Exactly.

One thing you should note is that the lzma format created by tar -c
--lzma -f is different from what tar -cf && lzma creates. (Yet another
GNU "feature", heh.)

During development I tested the later format, and the original patch
refused to work with the previous one, but Tim may have changed it since
then.

zip support has improved!
For example the problematic zip archives mentioned in that bug report
are now extracted properly :
http://bugs.archlinux.org/task/10941

Otherwise, pacman still seems to work fine without any rebuild.
