Discussion Topics
Releases
The 3.3.1 release was two months late, so we should rethink the release schedule. Every six months would seem to be more realistic.
- The 3.3.2 bug fix release expected 1st week of April
- The 3.3.3 release, no earlier than June unless we find serious problems
- The 4.0.0 release expected mid-July.
We generally support only the current minor release. We generally support the last minor release for one year after we produce a major release.
Next major release
The following items are planned for the 4.0.0 major release:
- IPV6
- Protocol bridge interface
- Readv passthrough (Brian Bockelman).
- I/O throttling plug-in (if we get it from Brian Bockelman)
- The new client interface will become stable if ready
- XrdPosix using the new client
- TXNetFile using the new client
- xrdcopy will be renamed to xrdcp and the current xrdcp replaces xrdcpold.
- Perhaps a wrapper or command line option for xrdcp to get previous version.
EPEL conformance
EPEL has created the RPMs for 3.3.1 and they are in the EPEL testing repository for EPEL5, EPEL6 and recent Fedora. They should be available in the EPEL stable repos soon.
The git repository
We are migrating to GitHub for source in the next few days and bug tracking before CERN moves to Jira.
VOMS plug-in
The updated VOMS RPM should be available by March 23rd. It is going to be separately released because it depends on the external VOMS library. It should go to OSG for US and EPEL for EU. We should touch bases with David Smith. This RPM will only available for 3.3.x.
Other items
- Python bindings will be ready for 3.3.2. They work with Python 2.4 and up and be distributed as a separate package. We plan to withdraw the Perl bindings.
- C++11 will be enabled when gcc 4.7 packages become available until then we will up the warning level and include server and client compilations to catch and fix problems.
- Exploring client-side plug-in to enable novel data access mechanisms.
