Description
Bi-Weekly "Loyal" DIRAC developers meeting.
And, following, the LHCbDIRAC developers meeting.
At CERN: Federico, Andre', Marko, Marcelo, Alexandre, Chris
On Vidyo: Andrei, Xiaomei, Ueda, Milosz
Apologies:
Follow-up from previous meeting
- LCGBundle 2017-05-23 is used in production in LHCb but still not properly announced on the DIRAC wiki
- v6r18 is a dead branch: releases removed
- gitHub project management: all issues that are not in DIRACGrid/DIRAC and WebAppDIRAC have been closed (and no possibility to open new ones)
Current situation
DIRAC:
- v6r17p24 is the last production version
- Only a minor fix
- v6r18 wiki and release notes will be merged in v6r19
- v6r19-pre2 is out
- Backward compatibility of RSS looks like fixed
- Using externals v6r6
- New gLogger -> logging code tested via hotfix in certification setup
- No problems up to now
- Included also change for allowing special payload error code to be interpreted by the jobWrapper(Template)
- e.g. for job rescheduling
- FTSFile: DB tables lengths extended (maybe to a not-so-smart value)
WebApp:
- NTR
Pilot:
- NTR
Externals:
- v6r6p2 compiled for both SLC6 and CC7
- openssl 1.0.2l as main feature
- not all versions of every package could go in (e.g. freetype) but managed to bump the versions of all the packages
- The post-installation script can be revised to absorb python-only extensions [Andrei]
- This may be a change in next major version of the externals
LCG bundles:
- New Versions v11r14 and v12r4 are in testing
- We discourage their use for now
- Next production version in late or after summer
PyGSI:
- Repository has been moved in the DIRACGrid/ organization on github
- New version 0.6.5 compiled and included in Externals v6r6 series
- Not yet put on PyPi
- Discussed possibility to link github repo to pypi
- Andrei advised to be careful because it's mostly C and not python
Release planning, tests and certification
Release planning:
- v6r17 series
- #3390 should be expanded including comments in #3388 (Ueda). Further discussed, agreement reached.
- #3402, #3404 can be included
- v6r19 series
- v6r19-pre will be created to include:
- #3405, #3407, #3408 can be included
- Too early to include MultiProcessor support
- [Externals v6r6p3]
- Should include also PR #31
- both SLC6 and CC7
- [WebAppDIRAC v2r2p4]
- Reminder: the full support of CC7 for DIRAC v6r19 can't be assured (issues are mostly external to DIRAC but nothing we can do)
- v6r19-pre will be created to include:
Certification process:
- NTR
CI tests:
- NTR, waiting for new pre-release
Weekly development(s) focus
- Nothing else to report (planning for release)
DIRAC: current PRs and tasks being worked on
- Nothing else to report (all PRs discusses)
AOB
- Suggested to add fts from alternative pypi repository [Federico]
- Suggested to check length of LFN fields in DBs [Chris]
LHCbDIRAC
- Next LHCbDIRAC version will be called v9r0
- First will be done based on v6r19-pre3
- Client release of LHCbDIRAC
- Asked about stopping deployment to AFS from v9r0
- Ben will discuss it at the Core SW: no answer yet?
- Deployment in dev area of CVMFS for pre-releases: decided to NOT pursue it
- Asked about stopping deployment to AFS from v9r0
- LHCbGrid:
- Mess, and more mess. Right now, the only working version is gcc49. Decided not to touch further for now.
