Description
Bi-Weekly "Loyal" DIRAC developers meeting.
And, following, the LHCbDIRAC developers meeting.
Bi-weekly DIRAC Development meeting -- 10/10/2019
At CERN: Federico, Zoltan, Christophe, Alexandre, Andre', Christopher, Vladimir
On Vidyo: Andrei, Igor, Daniela, Simon, Janusz, Hideki, Ueda
Apologies: Marko, Sasha, Xiaomei,
Follow-up from previous meeting
- vyPR presentation:
- the general feeling is that it's not something useful as of now
- main concerns are:
- lack of python3 support
- general support
- ROI unclear
- we might have a look at it again in the future, once we've migrated to tornado for our services
DIRAC communities roundtable
- CLIC:
- NTR, still on v6r21
- LHCb:
- NTR
- GridPP:
- Testing v7r0
- issues in separating the DIRAC environment from that of the users' applications
- originated 1 PR that want to split the environment
- issues in separating the DIRAC environment from that of the users' applications
- Using VMDIRAC for running on Openstack clouds, and SingularityCE
- Testing v7r0
- Belle2:
- issues reported on SiteDirector #4262 an #4263 fixed
- still on v6r21, but started moving to v622
- started looking into logs aggregation
- FranceGrilles:
- Moved to v7r0, but still sending Pilot2
- Rather smooth, the only thing found out is that RESTDIRAC is broken now (tornado version differ)
- EGI
- v6r22 used for most of the services
- once PRs for v7r1 will be merged, EGI services will start moving to it
Current situation
DIRAC
- v6r22:
- only minor bug fixes
- v7r0:
- a tag for v7r0p2 created.
- LHCb did a short hackathon with a release on top of DIRAC v7r0. Quite smooth.
- v7r1:
- second hackathon last week
- rather smooth
- second hackathon last week
VM:
- Should use Pilot3 instead of Pilot2, and use a new version together with DIRAC v7r0
WebApp:
- CERN IT notified us of possible XSS injections in the WebApp
- a fix has been created https://github.com/DIRACGrid/WebAppDIRAC/pull/354/files but subject to discussions
- Once approved, it should be backported to previous version
Pilot3:
- always creating a local pilot.cfg file for pilot configuration options
DIRACOS:
- v1r4 created and used in DIRAC v7r0 releases
Documentation
- NTR
OAuth2:
- NTR
tornado and other externals
- PR #4261 has been rebased on v7r1 and it's almost ready for merge (needs some more test)
Release planning, tests and certification
Release planning:
- v6r22 series
- NTR
- v7r0 series
- NTR
- v7r1 series
- Hackathon done last week. Maybe another one next week (than there won't be any during CHEP period)
- Integration (and v7r2)
- NTR
Certification process:
- NTR
Weekly development(s) focus
- Information system: BDII, GoCDB, CRIC...?
- VOs have the BDII2CSAgent installed and find it a necessary tool
- BDII is reported as dying
- LHCb is the only LHC VO that still use it
- CRIC advertised as its replacement, but seems to be for LHC VOs only
- CRIC2CSAgent might be added, but we better first check if there's the need of it
- Vladimir will check what's the source of info of CRIC
- If the source is GOCDB itself then we might do the work in DIRAC by simply extending GOCDB2CSAgent
- SystemLogging:
- VOs don't seem particularly interested in keeping it, as the ELK stack does more and better than that.
- Federico will circulate info on how to stop it, and create a PR to integration branch to remove it.
DIRAC: current PRs and tasks being worked on, or topics from Google forum
- https://github.com/DIRACGrid/DIRAC/pull/4286 is for running integration tests in CI
- can be merged!

Next BiLD in 2 weeks from now

LHCb
- https://docs.google.com/document/d/1U4DR-n7Omv4oKOmUaqvXkCTazsgGJG1ybfZYmat8Z9Y/edit?ts=5d8241f4
- document with a collection of operations, mostly for DB
- MySQL:
- several things to do (see doc), the first can be using the strict mode everywhere, also on MySQL 5.6
- The migration to 5.7 will need a downtime, to be planned
- Chris will talk with Ignacio to better define the plan
- Oracle will also need to be updated, maybe a downtime is needed
- Zoltan to verify and add it to the doc
- In the meantime: migrate slowly all our voboxes to CentOS7, with v6r22+DIRACOS
- Chris: started re-shuffling the puppet templates
- LHCbDIRAC v10r0:
- no news and no need for hackathon, but we'll need a release soon in LHCb-Certification setup for running MP jobs at CINECA HPC
