[oi-dev] ntfs-3g and fuse

[ken mays]

Hi Jean-Pierre,

The original sources are still here:
http://hub.opensolaris.org/bin/download/Project+fuse/files/fusefs-20100615.tgz
http://hub.opensolaris.org/bin/download/Project+fuse/files/libfuse-20100615.tgz

SFE patches (fuse*):
http://hg.openindiana.org/upstream/spec-files-extra/file/383896da4129/patches
I reviewed the fuse source up to fuse 2.7.6. Maybe someone can fork something from the fuse 2.8.7 branch.

I think I have now finished the first level debugging of
the fuse kernel module....

With the fixes, ntfs-3g passes the Posix file system test
http://www.tuxera.com/community/posix-test-suite/
except for a single test :

Failed Test                               Stat Wstat Total Fail  List of 
Failed
-------------------------------------------------------------------------------
/home/linux/fstest/pjd-fstest/tests/open/                3    1  2
Failed 1/191 test scripts. 1/1964 subtests failed.
Files=191, Tests=1964, 351 wallclock secs (19.50 cusr + 99.55 csys = 
119.05 CPU)
Failed 1/191 test programs. 1/1964 subtests failed.

The test which fails is the test for opening a fifo
named by ntfs-3g. Obviously this opening should be
bounced elsewhere, but I have no idea where....

There are a few other obscure things, which I cannot
clarify without the help of a Solaris VFS expert.
Reviewing of the code by a Solaris developer would
also be useful : there were a lot of memory leaks,
missing lockings, and forgotten unlockings. There
were obvious deficiencies in the quality management
of the initial version.

In the meantime, I consider the result as a release
candidate.

Please see http://b.andre.pagesperso-orange.fr/openindiana-ntfs-3g.html

By the way, where is the official OpenIndiana source
repository for this ? I saw Milan posting the patches,
but is not clear to me against what the patches were.
I can provide a list of patches per fix for a source
repository management.

Regards

Jean-Pierre
