Apologies:
Follow-up from previous meeting
MQ: ActiveMQ support could not verified (lacking proxy certificates support), so in current configuration only RabbitMQ passed fully an integration/system test. ActiveMQ could still be used with username/password and with standard certificates. To be discussed further later.
Current situation
DIRAC:
- v6r17p23 is the last production version
- Only a minor fix
- v6r18-pre14 is out
- Decided to go back to pre-releases, as it was discovered that RSS (main feature of v6r18) interfaces were not backward compatible.
- v6r18-pre14 looks like fixing this incompatibility
- New gLogger -> new logging code has been included
- Only used after hotfix
- Not
- Decided to go back to pre-releases, as it was discovered that RSS (main feature of v6r18) interfaces were not backward compatible.
WebApp:
- NTR
Pilot:

Externals:
- NTR
LCG bundles:
- Version 2017-05-23 is used in production in LHCb
- not announced properly, but it was agreed that it can be done, as this should be considered the recommended version as of now
- use version of xrootd 4.3.0 (relevant)
- A new bundle 2017-07-XX is in preparation, not successful up to now
- Aiming anyway at SLC6 + CC7 (complete)
- Updated FTS3 version
- Updated GFAL2 version
- Tried to bump xrootd version to 4.5.0 and 4.6.0
- 4.6.0 buggy - waiting for 4.6.1 which is not yet available
- Looks like libstd++ now needs to be distributed too (it was not the case)
- Compiled versions look to be different than before, mess is not yet sorted out
Release planning, tests and certification
Release planning:
- v6r17 series
- #3390 should be expanded including comments in #3388 (Ueda)
- v6r18 series
- Decided to declare v6r18 branch a dead branch (see problems above)
- This should be properly announced to the forum.
- v6r19 series
- All PRs now targeting v6r18 will be re-routed to v6r19, which become the new development version
- PRs for v6r18 of today's will become part of first tag v6r19-pre1
- PRs originally for v6r19 will become for v6r20 (or v7r0)
- [Externals v6r6]
- Compiled v6r6 version
- general bump of versions
- still problems with openssl (latest version could not compile, so used 1.0.2l)
- first tests on CC7 not successful
- pyGSI unable to create proxy
- SLC6 tests to be done
- Compiled v6r6 version
- [WebAppDIRAC v2r2p4]
- PR for it ready to be merged
- The full support of CC7 for DIRAC v6r19 can't be assured (issues are mostly external to DIRAC but nothing we can do)
Certification process:
- NTR
CI tests:
- NTR
Weekly development(s) focus
- Nothing else to report (planning for release)
DIRAC: current PRs and tasks being worked on
- Nothing else to report (all PRs discusses)
AOB
- gitHub project management: all issues that are not in DIRACGrid/DIRAC will be closed, and all future issues can go there
- obsolete projects will be closed
LHCbDIRAC
- Next LHCbDIRAC version will be called v9r0
- Client release of LHCbDIRAC (Invited Ben)
- Asked about stopping deployment to AFS from v9r0
- Ben will discuss it at the Core SW next week
- Deployment in dev area of CVMFS for pre-releases
- may not be available to all sites for grid use (Ben will check)
- We'll sit all together next week to do a clean one and document it.
- Asked about stopping deployment to AFS from v9r0
- LHCbGrid (kept from previous meeting, not discussed here as lack of time):
- gcc62 (and centOS) version are not fully working as of now as QT5 is still missing and QT4
- work done from IFT not complete
- This is still the only one thing missing
- so no BKK GUI
- This is still what is keeping us from modifying the default CMTConfig on lxplus6, which right now is fixed at gcc49
- gcc62 (and centOS) version are not fully working as of now as QT5 is still missing and QT4
