And, following, the LHCbDIRAC developers meeting.
At CERN: Federico, Christophe, Andre', Marko, Louis, Gergely, Zoltan
On Vidyo: Xiaomei, Daniela, Simon, Marcelo, Yash, Hideki, Ueda
Apologies:
Follow-up from previous meeting
- in 4 weeks we'll have one more BiLD on HTTPS and DIRAC
Current situation
DIRAC
- v6r19p24 out
- still the main production release for many
- just a fix for multiprocessor pilots
- v6r20p45out
- bug fixes
- multi-VO transformation system
- v6r21-pre1 out
- in DIRAC certification
- the next one will be called v7r0-pre1
WebApp:
- 2 PRs for v3r1 release ready -- will be introduced with v6r20
Pilot3:
- Andrei should include what's done for pilot2 with v6r19p24
Externals:
- NTR
DIRACOS:
- Marko: looks OK, just we depend on what redhat does
- Will be used for v7r0
- needs some changes in dirac-install script to allow extensions of it (ongoing)
- Using right now requirements.txt file taken from DIRAC repository
- needs to add a file with specific fixed versions in DIRACOS repo for everything pip-installable
LCG bundles:
- Chris found a bug in gfal2 (always there)
- reported, a fix will eventually come (not there yet)
- we are not sure we'll ever want to make more releases of lcgBundle anyway
REST:
- NTR
BOINC:
- NTR, docs still need to be completed
PyGSI:
- NTR
Documentation
- Some doc added for web, more should come
- in general, the web development should be made easier, using docker images
- Andrei still has to migrate the rest of the documentation for the agents inside the code
DB12:
- NTR
Release planning, tests and certification
Release planning:
- v6r19 series
- NTR (just a patch coming)
- v6r20 series
- Many PRs ready to be merged
- v7r0 series
- also many PRs to include
- the list of feature request is already closed
Certification process:
- v7r0 certification:
- to be started, but probably seriously only in few weeks
- https://jenkins-dirac.web.cern.ch/ is open to registrations for who needs it or wants it
- Federico showed a way how to use jenkins for testing ongoing developments
Weekly development(s) focus
- Python3:
- not yet the time for making real decisions, but awareness raised
- we should anyway start having code that is compatible python2 and python3
- tools are there, need to be explored
- Federico will invite an expert to present a possible way forward
- Should check:
- https://github.com/DIRACGrid/DIRAC/pull/3743
- here, only a subset of the modernize fixtures have been applied -- e.g. no use of six module
- https://github.com/DIRACGrid/DIRAC/issues/3696
- https://indico.cern.ch/event/694818/contributions/2985723/attachments/1680026/2702314/python-2-versus.pdf

- https://github.com/DIRACGrid/DIRAC/pull/3743
DIRAC: current PRs and tasks being worked on, or topics from Google forum
- Issue #3751: we agreed on keeping the directory operations only on the logical level
- some development need to be done before completely removing this option (see issue)
- Check #3710 if you want to clean the TransformationDB.DataFiles table
- Many PRs waiting for final review
DIRAC communities roundtable
- BES:
- NTR
- CLIC:
- Moved to v6r20 in production yesterday
- LHCb:
- NTR
- Belle2:
- NTR
AOB
- CHEP highlights:
- Use of HPC growing even more
- ATLAS converging on using Harvester
- a kind of "small installation" that acts as a local-to-a-HPC pilot factory
- we can probably do the same in DIRAC with what we have already, Federico thinks it's just how to configure it
- ATLAS converging on using Harvester
- no questions on DIRAC-Rucio interoperability!
- Use of HPC growing even more
- Next BiLD-Dev meeting will be held in 2 weeks (August 2)
LHCbDIRAC
- v9r2 certification
- CC7 client needs to be tested still
- LHCbGrid released, looks OK, but done in a patchy way
- so we better wait for at least Ben to be back before releasing
- release date (after consideration): July 30
- Zoltan won't be around, Chris and Federico will
