OpenAFS Newsletter, Issue 3, July 2009

Welcome to the third issue of the OpenAFS newsletter. The newsletter summarizes what is happening in the OpenAFS community. The main thing to report in this issue is the conversion of CVS to git. Git is now ready for use in development. I suspect that many people were very busy or on vacation this month, because many of the subprojects did not reply to requests for project updates.

As always, volunteers, patches, bug reports, or any other type of help is greatly appreciated.

Feedback on this newsletter is welcome. The goal is to summarize the various development efforts and news of OpenAFS for the community. Please let Jason Edgecombe <jason@rampaginggeek.com> know what you would like to see out of this newsletter.

The current and past issues of this newsletter are available at http://www.openafs.org/newsletter/

General OpenAFS Progress

Many thanks go to Simon Wilkinson for finishing the conversion from CVS to git and setting up gerrit. Gerrit has only been up for a week and there are already over 100 patches that have been merged!

1.4.11 has been released, and it includes major bugfixes for Linux clients and fileservers. Some minor bugs were fixed on other platforms. The release notes are available at http://www.openafs.org/frameset/dl/openafs/1.4.11/RELNOTES-1.4.11

Events

AFS Hackathon

The School of Informatics at the University of Edinburgh will be hosting an AFS Hackathon 22-24 September (immediately before the European AFS Conference). All OpenAFS developers are welcome to attend - please see the email to openafs-announce for details, and RSVP to sxw@inf.ed.ac.uk

Annual Best Practices Workshop

Plans are already underway for the seventh Workshop, to be held May 24-28, 2010, at the University of Illinois at Urbana-Champaign. We hope to see you there.

Projects

Security Releases

Security Officer:

No security issues since 1.4.9, 1.4.10, and 1.5.59 were released in April 2009.

Git

Project Contact:

During the week of 6th July, we completed our transition to the git version control system. Git, and gerrit (our code review tool) are now ready for use! See http://www.dementia.org/twiki/bin/view/AFSLore/GitDevelopers for more details.

Pthreaded Ubik

Project Contact:

The pthreaded ubik's initial code delivery to provide for use of POSIX threads instead of LWPs was made in April 2008. After some production usage, some problems were found in initialization (on certain platforms) and lack of locking, leading to data corruption in some cases for the vlserver. As part of the analysis of these problems, some differences were identified between the private version of OpenAFS being used and the version in OpenAFS HEAD, several other longstanding issues with vos, vlclient, and the vlserver were identified, and some patches have been submitted:

Current work involves cleaning up and testing a patch to fix improper handling of multi-homed IP addresses in the VLDB. The patches to fix the logging are undergoing further testing and analysis (both code review and automated testing with Helgrind), and we hope to have those submitted soon as well.

Rx OSD integration & Raw Vicep Access in Clients

Project Contacts:

The RxOSD-integration is now documented at http://pfanne.rzg.mpg.de/trac/openAFS-OSD. This website offers technical documentation as well as links to prebuilt rpm- packages for some distributions (CentOS,Fedora, Mandriva, RHEL, openSUSE, and SLES). Anyone willing to contribute is cordially intvited to drop a line to the maintainers. Patches are currently being prepared and targeted at the 1.4.x stable branch, they are published on https://dvinfo.ifh.de/AfsOsd/Patches. Patches for 1.5.x are coming up.

Google Summer of Code 2009

OpenAFS received four slots for the 2009 Google Summer of Code.

Go to http://socghop.appspot.com/org/home/google/gsoc2009/openafs for more information about the GSoC projects.

Three of the projects are still active. Unfortunately, one student had to back out.

The following projects did not give a status update:

OpenAFS Management Console on Windows

Student Developer: Brant Gurganus <brant@gurganus.name>

Mentor: Jeffrey Altman <jaltman@secure-endpoints.com>

Self-intro: https://lists.openafs.org/pipermail/openafs-devel/2009-April/016591.html

The Google Summer of Code program is at its half way point. With that, the management console has a complete user interface as well as deployment packages. Project downloads and source will be available at http://code.google.com/p/openafsclientmmc

Projects with no progress or no update

Resolved Tickets

Since Gerrit is now the preferred method of accepting patches instead of RT, it's likely that fewer RT tickets will be filed.
