Release planning, tests and certification

Release planning:

  • v7r0 series
    • Last PRs in the pipeline (dirac-install++ and ProductionSystem) are all ready for merging
    • M2Crypto PR awaiting

Certification process

  • v7r0 certification:
    • certification instance updated by Zoltan, but web isn't working

Weekly development(s) focus

Directory operations on storage: there's an agreement that they should be declared as deprecated. All directory operations will be "virtual", on the DFC only. 

Some agents (e.g. ValidateOutputDataAgent) and ConsistencyInspector should be reviewed in this sense.
