Follow-up from previous meeting
- DUW 4 weeks ago
- feedbacks in https://docs.google.com/forms/d/1C67pOX0UwulLsh-LZeDFq4IaJlmcCmRlTSqtYmTSdeM/
- PR (#3713) for fixing the infamous "invalid action proposal" by speeding up the handshake and not looking up the user/group in the baseStub: backported to v6r19, working as expected. In production for many now.
- does the OSCompatibility section in CS need to be kept up-to-date? Not sure, to be checked.
Current situation
DIRAC
- v6r20p3 out
- used in test from CLIC and GridPP and LHCb
- v6r21-pre1 out
- in DIRAC certification
WebApp:
- v4r0 looks "ready", won't depend from any specific DIRAC release
- ready to be merged and to be part of DIRAC v6r21
Pilot3:
- Wijtech working on tests in Jenkins
Externals:
- NTR
DIRACOS:
- pushed to https://github.com/DIRACGrid/DIRACOS the first version
- checked by Marcelo
- some documentation unclear/missing
- once done a new tested (proposed Marko) will try it one more time
- ready to be used already for v6r21
- needs some changes in dirac-install script
LCG bundles:

BOINC:

Documentation
- At the DUW we agreed on putting more technical info in the docstrings of the DIRAC components
- Andre' has added in PR #3723 the technical documentation to start/administer two TS agents.
- Anyway we agreed to not use the tabular format, but rather to add some snippets of the CS
- This PR will "set the tone (the format)" on how to write this technical documentation.
DB12:
- NTR
Release planning, tests and certification
Release planning:
- v6r19 series
- NTR (just a patch coming)
- v6r20 series
- v6r20p3 created today, ready for v6r20p4
- #3726, #3725, #3722
- v6r20p3 created today, ready for v6r20p4
- v6r21 series
- v6r21-pre1 is out
- for this series, we agreed that DIRACOS will be used
- also WebApp 4.0 can be used
- this takes us to name this release v7r0
- the list of feature request is already getting closed
Certification process:
- v6r21 certification:
- v6r21-pre1 installed already in DIRAC certification setup
- https://jenkins-dirac.web.cern.ch/ is open to registrations for who needs it or wants it
Weekly development(s) focus
- dirac-install ++ follow-up
- based on task #3517
- ongoing PR: #3678
- we need to be careful to keep the backward compatibility, as many instructions point to use the version found in integration branch.
DIRAC: current PRs and tasks being worked on, or topics from Google forum
- PRs:
- #3703 on new production system: several comments, not for today (Luisa not present). Won't be merged, for now
- #3724: can be merged anyway, the actual deployment should anyway be done by hand (DB operation)
- #3723: Multi-VO transformation system. Not much code, actually. No need for changes at the DB level
- Forum:
- GridPP installing the transformation system. Quite some work to actually fix the CS correctly. Interested in #3273.

- BES:
- Moving to v6r20 next week
