Follow-up from previous meeting
- GS DOCS: google evaluating students. We got a few applications
DIRAC communities roundtable
- CLIC:
- moved to v6r21
- LHCb:
- Will use SIngularity containers from next LHCbDIRAC release for application only (for software preservation purposes)
- this has nothing to do with payload isolation, and it's not done via DIRAC tools
- Will use SIngularity containers from next LHCbDIRAC release for application only (for software preservation purposes)
- GridPP:
- Moved to Centos7 servers. Created and using new lcgBundle for glite software, only for Centos7: re-packaged by just adding a few packages.
- Belle2:
- Preparing to move to v6r21 next week
- Juno:
- deploying production system (TS)
Current situation
DIRAC
- v6r21:
- v6r21p10 is the last patch release
- Minor fixes only
- v6r21p10 is the last patch release
- v6r22:
- Will be created today
VM:
- NTR.
WebApp:
- Web 4.0: several fixes done, a few more issues open
- suggestion to close those issues that have already been tested
- JSLint can be added for Travis tests [Zoltan]
Pilot3:
- One PR from Andrew for using MultiLauchAgent
- will probably not accepting it
- asked to move to use instead the PoolCE
DIRACOS:
- v1r2 created
- ldap and ARC looks like fixed
- changed the baseline from SLC6 to CentoOS6 (because IT broke some dependencies)
Documentation
- NTR
OAuth2:
- Can be moved to integration branch, as not fully ready
DB12:
- NTR
tornado and other externals
- New release of M2Crypto containing a fix that we need.
- Chris will test it
Release planning, tests and certification
Release planning:
- v6r21 series
- NTR
- v6r22 series
- will create today
- v7r0 series
- a rel-v7r0 branch can be created as soon as v6r22 is out, starting what is now in
- what won't be there will go integration (v7r1?)
- will start certifying it already next week
- a rel-v7r0 branch can be created as soon as v6r22 is out, starting what is now in
Certification process:
- dteam VO used for DIRAC certification setup
- access to certification server box (lbcertifdirac7) granted to who requested it
- going apparently quite fast
- added a few sites for testing HTCondor, ARC, CREAM CEs, and mcore queue
- Next week we can start v7r0-preX certification
Weekly development(s) focus
- Created a PR for testing python 3
- discovered that we are pretty far, and that certainly it won't be possible to move to python 3 before moving out of DEncode (unicode will be killing us)
DIRAC: current PRs and tasks being worked on, or topics from Google forum
- Almost all PRs discussed and reviewed
- codecov a bit annoying. Bring patch down to 1% target, or even 0 [Andre']
AOB
NTR
Next BiLD in 2 weeks from now.
