- New gLogger -> logging code can be included as long as it will not break anything
- old code will still be used for v6r18
- [v6r19] List of topics to include discussed today
- Pilots logging (see below) should be the main point
- Optional:
- A partial replacement of pyGSI with M2Crypto
- FTS3 (promised to be "non intrusive")
Certification process:

Weekly development(s) focus
pilots logging
Clarified that pilot logging is NOT pilot log, which is a different topic. The pilots log centralization is not discussed in depth here, even though some of the tools developed for pilots logging can be re-used, specifically the MQ machinery.
2 parts:
- Pilot. Work done in pilot 3 repo since long.
- need to fix JSON file from where to get bootstrap info like host, port, queue names
- generate allCAs.pem file and put in CVMFS for stomp SSL connection
- deploy instructions should be added.
- Server. PR #3360. Installed in DIRAC certification machine just for testing, working OK. Noticed that the consumers were missing, developed lately. Minor fixes needed.
A full integration test has been done using the DIRAC certification machine and a RabbitMQ server deployed on lbvobox50.cernc.ch. The test can be considered successful.

LHCbDIRAC
- LHCbGrid:
- 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
- LHCbDIRAC v8r8 is in production
- LHCbDIRAC v8r9 preparation
- only adopting DIRAC v6r18 and LHCbGrid v12r0: https://gitlab.cern.ch/lhcb-dirac/LHCbDIRAC/wikis/home
- Need to re-do Stavors MR
- only adopting DIRAC v6r18 and LHCbGrid v12r0: https://gitlab.cern.ch/lhcb-dirac/LHCbDIRAC/wikis/home
