Yes, I'm realistic about it - it is "horribly beta" :) Two reasons: one: I couldn't amass enough interested parties to help test it (and possibly work on it), and second: while it's a nice problem to tackle, I don't [yet] need it that badly to start working on it outside of free time). In any case, TDFS doesn't have locking because FUSE doesn't have it (or didn't when I started doing it), so it stays single-writer-multiple-readers until that changes. I'm thinking of re-creating it in kernel mode (and in this form it could also have locking) but not any time soon. Maybe during the summer (SoC? probably.). --------------enig34D9E7B78EA9224567D4C440 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFF0f7ildnAQVacBcgRAgLmAKDLJ6+65xAyR1C8Drue2g5nZFH6rwCgmG9l BguPYBTfFQr59E1yYbiaGtY= =Pb5x -----END PGP SIGNATURE----- --------------enig34D9E7B78EA9224567D4C440--
