only un-answered topics with discussion updates:
DIRAC releases
DIRAC projects
DIRAC:
- “RFC” for how/what to use/put in CVMFS
Issues by milestone:
- v8.0:
- 10+ open issues, not much movements
- v9.0:
- 20 open issues, as usual some movements
Other issues:
PRs discussed:
DiracX:
- New DiracX version 0.0.1a14, mostly for fixing DIRAC CI
- Several large-ish PRs to be evaluated
- Web: https://github.com/DIRACGrid/diracx-web/pull/131 (already merged)
- dashboard with draggable applications and groups
- applications and their states are saved directly in the URL: can easily share a whole set of application through a simple link (might hit some URL length limitations at some point but it works well for what we have now).
