Follow-up from previous meeting

• JSON encoding: PRs #3585 and #3586 have been merged for v6r20
• FTS3: last PR merged in v6r20 pre version, looks OK right now
• Reminder to check the old sandboxes for deletion

Current situation

DIRAC

• v6r19p13 is the last production version
  • Mostly fixes
  • Now support for lastest version of ElasticSearch should be OK

WebApp:

• The new release procedure of WebApp has been merged, part of v6r20
  • Documentation needs to be updated
  • Test not fully done yet
• Test for moving WebApp to ExtJS6 ongoing, almost finished
  • Will be for 4.0 version of WebAppDIRAC
  • NOT for DIRAC v6r20, later
  • Extensions would need to be adapted
  • Branches like in DIRAC should be introduced also for WebAppDIRAC [Zoltan]

Pilot:

• Wojtek working on few PRs

Externals:

• v6r6p4 created. Used in v6r20
  • only for SLC6 for now, so that certification can keep going 
  • at the end it will be also for SL7
• For future: everything that can be installed with pip install should go in "post installation"
  • Andrei looking into it: https://github.com/DIRACGrid/DIRAC/issues/3444
  • have to figure out how to handle which python version to use
    • not exactly trivial
    • Joel to send a command to Andrei (used in LHCb vo-boxes)

LCG bundles:

• current production version is v13r0
• 4 or 5 new versions of packages of the Grid middleware are available, so new version of the lcgBundle will come
• need to update the wiki
• Daniela reported need to add in $PYTHONPATH the path for locally installed packages (see slide)
  • Doesn't look like it's something you want to do
  • Daniela will send to Joel the command that fails
• Daniela asked to re-include LFC support

REST:

• Wojtek will create PRs as soon as possible for:
  • choosing among different authentication methods (OAuth and X509)
  • adding the pilots logging interface
  • Delayed because of issues discovered in the DIRAC stomp interface
  • ...and because of code refurbishment
• 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, docs still need to be completed

PyGSI:

• NTR

Documentation

• NTR, just one user asking for better doc for lcgBundle (which we can't fully provide)

DB12:

• NTR

Release planning, tests and certification

Release planning:

• v6r19 series
  • NTR
• v6r20 series
  • pre12 out
  • only one PR with new features (for space occupancy) still need to be included

Certification process: 

• v6r20 certification: 
  • Using trello and slack as usual
  • Some progress lately
    • mostly done by Zoltan

Weekly development(s) focus

• Move to Web API [continuation from last week]
  • whatever is produced will need to be tested carefully, especially comparing it performances with DISET based implementation
  • Question about "restarting the single handlers"
  • Some things like multiprocessing and JSON are going already in DISET 
• ARC CEs
  • Daniela reported still issues and need for "patching" from ARC users
  • glue2 support still not there [Vladimir to look into it]
  • [Raja + Andrei + Daniela] to look in details

DIRAC: current PRs and tasks being worked on

• NTR

DIRAC communities roundtable

• GridPP:
  • Collecting new users, and losing 2 (US based moving to glideinWMS)
  • Tags and matching not perfect yet
  • Some operational and maybe scalability issues with MySQL and services
• CTA: working on next devs of TransformationSystem (kind of Production Management System)
  • Some French VOs (LHCC, CreativLab, BioMed) interested in using the TS for their production
  • Asking for dedicated tutorial at the DUW
• ILC: NTR
• LHCb: 
  • Trying to update the MySQL version to 5.7
    • performance issues, not yet fully sorted out
    • a post mortem will come at some point
• CNAF (Italian Grid DIRAC service): Virgo the main user-to-be
• DIRAC4EGI:
  • sorting out several things
    • including actual support
    • Andrei involved
  • several VOs interested

AOB

• Next BiLD-Dev meeting will be held in 2 weeks (February 22)

LHCbDIRAC

• We should right now concentrate on testing v6r20
  • And then we decide what to base v9r2 on
    • Philippe's PR may probably be included, maybe not alone
• 4 students this summer
  • for 3 of them their project include using ElasticSearch
