Current situation
DIRAC
- Just patches for v6r19
WebApp:
- Security breach (unauthorized uploads from web portal) should fixed with version in certification
- need a certificate right now
Pilot:
- Wojtek PR for pilot logging: slowly progressing
- still want to add more complete integration tests for both REST and MQ cases, to be used together RESTDirac and our MQ components, so keeping the [WIP] flag for this moment.
- Pilot3 will become optional for v6r20 SiteDirectors, using a flag [Federico working on PR right now]
- Currently Pilot3 files are uploaded to the web portal
- Needs to update the documentation for that
- Currently Pilot3 files are uploaded to the web portal
Externals:
- v6r6p6 created. Used in v6r20, looks OK for now
- only for SLC6 for now, so that certification can keep going
- CentOS7 version is anyway needed
LCG bundles:
- v14r0 and v14r1 created. In testing right now (all looks OK)
- Mostly for xroot and gfal2 versions
- LFC support re-included
- No changes wrt v13r0 and the CentOS 7 support
- see wiki for more details
- current production version is still v13r0
- DIRACOS: created a first working version
- which can be installed using a flag in dirac-install.py script
- looks OK at first tests, but only for SLC6
- support for CC7 need some tweaks, investigated right now
- for the moment is LHCb-ish but can be easily adapted
- need to use Jenkins or other CI system
REST:
- NTR
BOINC:
- NTR, docs still need to be completed
PyGSI:
- NTR
Documentation
- Louis going through the Dev documentation
- some issues when using SLC6 (python 2.6 as default)
- also unclear how to handle the certificates
DB12:
- NTR
Release planning, tests and certification
Release planning:
- v6r19 series
- NTR
- v6r20 series
- preX out
- contains all the new features, so now it's only about testing
- the flag for enabling bulk submission transaction can be removed [Federico -> PR done]
- FTS -> FTS3: no way to move files, need draining
- we enabled shortly the flag that tells us what JSON can't parse, and got lots of errors
- need to see if really needed
Certification process:
- v6r20 certification:
- Using trello and slack as usual
- Some updates as usual
- We need to (re)start all tests with the new lcgBundle and External
Weekly development(s) focus
- Glue2 support not in Bdii2CSAgent neither [Andre + Vladimir]
- https://github.com/DIRACGrid/DIRAC/issues/3633
- HTCondorCEs at CERN now not advertised anymore in Glue1
- Andre looked into in and found out Glue2 is supported in a different way everywhere
- big confusion
- the suggestion is to look to make it work, for the moment, on our side, ONLY for HTCondor CEs at CERN
- https://github.com/DIRACGrid/DIRAC/issues/3633
- ARC CEs (no progress)
- still sites need to install patches for DIRAC to understand its content
- glue2 support still not there, not sure if with that it would work [Vladimir to look into it]
- [Raja + Andrei + Daniela] to look in details
DIRAC: current PRs and tasks being worked on, or topics from Google forum
