Follow-up from previous meeting
- lcgBundle: nothing new for the moment, but we said we actually need a new version
- which should come max on Monday
- Release procedure for webApp updated
Current situation
DIRAC
- v6r19p16 is the last production version
- just fixes for the pilot, and matching on MP resources
- tested by GridPP, looks working OK for their need now
- just fixes for the pilot, and matching on MP resources
WebApp:
- The new release procedure of WebApp part of v6r20 is OK
- Test for moving WebApp to ExtJS6 ongoing, finished
- Will be for 4.0 version of WebAppDIRAC
- NOT for DIRAC v6r20, later
- Extensions would need to be adapted
Pilot:
- Wojtek created a PR for pilot logging
- still want to add more complete integration tests for both REST and MQ cases, to be used together RESTDirac and our MQ components, so keeping the [WIP] flag for this moment.
- Jenkins tests are now easier to use and can be used for testing the above
- Pilot3 will become optional for v6r20 SiteDirectors, using a flag [Federico]
- Currently Pilot3 files are uploaded to the web portal
- there is a security breach here that needs to be fixed. [Zoltan]
- Needs to update the documentation for that
- Currently Pilot3 files are uploaded to the web portal
Externals:
- v6r6p5 created. Used in v6r20, looks OK for now
- only for SLC6 for now, so that certification can keep going
- For current Externals, Federico created https://github.com/DIRACGrid/Externals/pull/37 which compile python with pip
- then old ez_setup and other deprecated stuff has been removed
- What Chris and Marko are doing for the lcgBundle can one day completely replace the Externals too
LCG bundles:
- current production version is v13r0, but 4 or 5 new versions of packages of the Grid middleware are available, so new version of the lcgBundle will come. Also needing new xroot and to re-include LFC support.
- This was not done but it's now high priority, and needs to come NOW
- Chris and Marko are look into re-compiling everything, starting from the source RPMs provided for RedHat 6. Then, for DIRAC to use it we need to change dirac-install to accept a new flag, e.g. DIRACOS flag that can be used for pointing to this new bundle[Zoltan to help]
- for the moment only creating one version (no client/server)
- need to use Jenkins or other CI system
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:

Documentation

Release planning, tests and certification
Release planning:
- v6r19 series
- make v6r19p17 before next week
- v6r20 series
- pre15 out
- contains all the new features, so now it's only about testing
- the flag for enabling bulk submission transaction can be removed [Federico]
- FTS -> FTS3: we should develop a script to move files from old to new system [Hamza with the help of Chris]
- we enabled shortly the flag that tells us what JSON can't parse, and got lots of errors
- we need a first visual evaluation and remove the obvious ones [Chris]
Certification process:
- v6r20 certification:
- Using trello and slack as usual
- Some updates as usual
- We need to (re)start all tests with the new lcgBundle
Weekly development(s) focus
- Glue2 support not in Bdii2CSAgent neither [Andre + Vladimir]
