[Dazuko-devel] DazukoFS 3.0.0-rc3 posted

[John Ogness]

Hi,

I have posted the next release candidate for DazukoFS 3.0.0. Normally
with release candidates, new features should not show up. However,
since 3.0.0 is introducing a completely new interface (and features),
I am allowing important features to creep in during release
candidates.

That being said, a new feature called "group tracking" has been
added. Applications can activate this for their group using the
DAZUKOFS_TRACK_GROUP flag:

dazukofs_open("mygroup", DAZUKOFS_TRACK_GROUP);

If this flag has been set for a group, the registered applications for
that group will be tracked by DazukoFS. As soon as the last file
descriptor to that group has been closed, DazukoFS will automatically
remove the group (i.e. dazukofs_close() before exit() becomes
optional). This is useful to prevent DazukoFS mounts from hanging if
registered applications crash (or are killed with SIGKILL). This is
quite an important new feature and one which is _not_ available in
Dazuko 2.x.

The "showfiles" example provided with the DazukoFS package uses this
flag.

This new version has been modified to support Linux 2.6.27. A patch is
provided in the package to allow the DazukoFS code to be patched to
work with Linux 2.6.26. I like the idea of using patches rather than
defines. We'll see how long I can keep that up.

I am absolutely thrilled with the performance and stability of
DazukoFS. I have written a simple WindowMaker applet based on DazukoFS
that shows the number of files being accessed on my system. I
typically access about 80,000 files a day.

I have had absolutely no problems. And I can start the "showfiles"
application at any time to additionally see what files are being
accessed. In my opinion DazukoFS is already superior to Dazuko in
every aspect (performance, security, stability, feature set).

I welcome anyone who can manage to get DazukoFS to hang or crash.
