and includes support for Leopard, Solaris 10-update 4, and new Linux
- Bug fixes proposed for 1.4.6
include verifying viced-accurately-track-file-callbacks-20071112 fixes
the bug seen with CBFree/FEFree corruption, viced-missing-lock-20071109,

- Pending work includes module
unload cleanup, afs_HashOutDCache panic, and an Rx error.
- Longer term, there is work
planned to stabilize 1.5 so that we are able to put out 1.6 series releases.
There has also been discussion with the HEPiX community regarding a
timeout issue which limits AFS throughput. Derrick is working
with Rainer Toebbicke regarding his Rx test tool to resolve this matter.
He is also working with Hartmut Reuter to integrate his AFS+Object Storage
code. However, the timing of this work depends on the availability
Jeffrey Altman (Windows Development)
There have been three OpenAFS for Windows
releases since the last Elders meeting: OpenAFS 1.5.25 (9/20/07),
1.5.26 (10/23/07), and 1.5.27 (11/7/07). Details of these releases
can be found at openafs.org.
The following changes have been made post
- Optimization of the performance
of the Windows cache manager.
- A new option which permits
.readonly callbacks to be automatically renewed prior to expiration.
This option can reduce load on .readonly volumes over long periods of
time. However, it is an optional feature since it will result in a single
FetchStatus request being sent per .readonly volume whether or not the
client is actively using that volume.
Future work plans for OpenAFS Windows
- OpenAFS Redirector work (in
- OpenAFS File System Filter
Driver that will permit \\AFS to be used without requiring the presence
of the Microsoft Loopback Adapter.
- Implementation of Extended
Attributes by storing data in the Apple Double Files as described in
Russ Allbery (Debian & Documentation)
- 1.4.5 packages have been uploaded
- The 1.4 backport of the Kerberos
multiple-realm patch will be pulled into the Debian packages so that
it can be more broadly tested.
- There will be additional work
to improve Documentation, including Russ committing pending contributions
from Jason Edgecombe.
- Stanford and Sine Nomine are
pursuing a file server problem that's causing periodic segfaults due
to an apparent free list corruption. Once this bug is identified
and fixed, it should be included in a 1.4.6 release.
- Russ is going to try to get
some resources at Stanford to start testing the demand-attach fileserver.
Council of Elders - Member Resignation
Warren Yenson has resigned from the OpenAFS
Council of Elders since he is no longer actively involved in OpenAFS
development or with OpenAFS customers. Warren had been closely
involved with OpenAFS in his position at Morgan Stanley, but he has
not been involved with AFS in his position at Google. However,
Warren has kindly offered to talk with the Google Android team members
about possible opportunities with OpenAFS. The Council of
Elders would like to thank Warren for his contributions to OpenAFS and
wish him well in the future.
