Description
Bi-Weekly "Loyal" DIRAC developers meeting.
And, following, the LHCbDIRAC developers meeting.
At CERN: Federico, Christophe, Zoltan, Philippe, Joel, Wojtek, Andre', Marko, Hamza, Xiaomei
On Vidyo: Marcelo, Raja, Milosz, Daniela, Simon
Apologies: Andrei
Follow-up from previous meeting
- FTS3 policy: fine
- autopep8: need to find the proper strategy
Current situation
DIRAC:
- v6r19p7 is the last production version
- v6r19p6 was buggy, and not properly announced/removed, apologies
WebApp:
- The new release procedure of WebApp has been merged, will be part of v6r20
Pilot:
- NTR
Externals:
- NTR
LCG bundles:
- v13r0 includes python packages like pyparsing and futures, which should be anyway in the externals. To verify
- still not moved its "development" to GitHub. This would also answer the recurrent question of the content of each release
REST:
- Wojtek will create PRs as soon as possible for:
- choosing among different authentication methods (OAuth and X509)
- adding the pilots logging interface
- The connection with CS-based authZ will be done later
- Tornado proposes some unit/integration tests which look easy to use, and that can be integrated in Travis or Jenkins. Maybe also for WebApp.
BOINC:
- NTR
PyGSI:
- NTR
Documentation
- Improved creation of scripts documenttion
DB12:
- NTR
Release planning, tests and certification
Release planning:
- v6r19 series
- v6r19p8 should be out today

- jenkins-dirac server is OK
Weekly development(s) focus
- RAL is moving from Castor to ECHO. No SRM.
- DIRAC is not fully ready yet. Mostly operational but with some developments to be done
DIRAC: current PRs and tasks being worked on
- #3554 (Transactional bulk jobs submission). Comment is that jobs that can't be submitted should not be considered as "Failed"
- pyGSI -> M2Crypto: maybe for v6r21
- Made several tests
- Removed the legacy proxies part
- Added a flag to use it or not, based on an environment variable
- sockets part being added
- dirac-wms vs dirac-admin scripts: time to change the names?
- Philippe will make a plan for changing names and positions altogether
DIRAC communities roundtable
