Follow-up from previous meeting

• DUW 2 weeks ago
  • for next time:
    • we may even account for more discussion
    • we may possibly schedule beforehand some "private" discussion
    • and maybe do a first day with ONLY introductions
  • the introductory part was good for the tutorial
  • we should send a mail or survey asking for feedback [Federico]
• Simon and Chris worked on a PR (#3713) for fixing the infamous "invalid action proposal" by speeding up the handshake and not looking up the user/group in the baseStub
• does the OSCompatibility section in CS need to be kept up-to-date? Not sure, to be checked.

Current situation

DIRAC

• v6r20 out
  • also v6r20p1
  • used in test from CLIC and GridPP

WebApp:

• one PR to be merged
• v4r0 looks "ready", won't depend from any specific DIRAC release
  • compiled ExtJS6 can be distributed without licensing issues
  • possibility to distribute ExtJS6 (compiled) to cvmfs? e.g. in dirac EGI  
  • anyone that has an extension need anyway to recompile, and so needs to have an account on Sencha

Pilot:

• Pilot3: PR adding stomp and rest and localFile message logger accepted in devel branch.
  • Wijtech added a small PR that changes imports of stomp and requests to the class scope of Message Senders.
  • The Jenkins test for local sender is ready and active.
  • The next step will be to setup the ActiveMQ test on jenkins combined with corrections in DIRAC MQ components. After that, the REST rewriting and setup of "final" tests.

Externals:

• NTR

DIRACOS:

• pushed to https://github.com/DIRACGrid/DIRACOS the first version
• ready to be used, maybe already for v6r21

LCG bundles:

• v14r1 is right now the "official" bundle for DIRAC v6r20
  • May need an update soon, possible bug discovered
  • new versions of fts3, gfal2, xrootd should be included
  • CC7 version does not include M2Crypto [to be fixed still]

REST:

• NTR  

BOINC:

• NTR, docs still need to be completed

PyGSI:

• NTR

Documentation

• Several documentations updated
  • Zoltan wants to further add to the accounting documentation
• At the DUW we agreed on putting more technical info in the docstrings of the DIRAC components
  • Andrei will submit a PR to "set the tone (the format)" on how to write this technical documentation. The SiteDirector and the Matcher will be used as example.

DB12:

• NTR

Release planning, tests and certification

Release planning:

• v6r19 series
  • NTR (just a patch coming)
• v6r20 series
  • v6r20p2 will be created today
• v6r21 series
  • we can start v6r21-pre1. The list of PRs that can go in:
    • #3702 : removed unused/outdated stuff from Distribution module
    • #3701 : Grouping loaders (should be advertised in the wiki in order to avoid surprises in the extensions)
    •  

Certification process: 

• v6r21 certification: 
  • will be started next week or the week after

Weekly development(s) focus

• dirac-install ++
  • see attached presentation
  • based on task #3517
  • ongoing PR: #3678
  • the only thing we agreed on was to write down the specific use case we have in the task above
  • the only possible conclusion we have from today's discussion is that we want to installed software, released or not released, in a "composite" way. The source should be... whatever (git repo, local, remote, zip,...).

DIRAC: current PRs and tasks being worked on, or topics from Google forum

• PRs:
  • #3703 on new production system: several comments, not for today (Luisa not present). Won't be merged, for now
  • #3708 on using the ES for JobParameters
    • have to be careful not to intersect with JobAttributes, which should not go ES
    • at some point we will need to look into doing performance testing
    • this PR can MAYBE be merged already
• Forum:
  • North African Grid group wants to use DIRAC for *everything*

• Louis work is ongoing, a prototype will be at some point ready, it could possibly go as a DIRAC extension
