Weekly development(s) focus
Andrii Litovchenko presented the work being done for EGI for integration EGI check-in service and OAuth2. The work is very intereststing, and presents some challenges (see pres attached to the agenda).
The discussion focused on how to interact and integrate HTTPS services in DIRAC. The work presented uses the current webportal for creating a DIRAC OAuth2 service, and proposes to move the base code of WebAppDIRAC to DIRAC. This was felt partly in contrast with what was agreed long time ago and that was added as solution in https://github.com/DIRACGrid/DIRAC/pull/3815.
The agreed solution is:
- close #4055 (so, not adding WebApp files to DIRAC, just leave them there)
- create a new DIRAC extension (e.g. OAuth2DIRAC) where to put the content of #4037 (the new service)
- this extension would need WebAppDIRAC
- add this extension to v6r22
DIRAC: current PRs and tasks being worked on, or topics from Google forum
- NTR
AOB
- CHEP abstracts: going to submit one for DIRAC, generic
- DUW agenda ready
Next BiLD in 5 weeks from now.
