Current situation
DIRAC
- made v6r20p26 with the few bug fixes PRs that we have right now
- maybe the last patch of v6r20 release series
- moved more problematic PRs to new release v6r21 that includes:
- PR for FTS #3922 (requires DB changes and running a script)
- PR for modifying the PYTHONPATH of pilots #3923
- backport of dirac-install from integration branch, with a couple more fixes that will come
- this will give us possibility to install optionally DIRACOS
- 3 pre-releases up to now
- plan to release very soon
WebApp:
- Just one PR to be included in the next production release (being it v6r20p27 or v6r21)
Pilot3:
- Federico added mostly tests, and portings
- Wojciech and Danyil have a minimal working prototype for the rest https tornado-based interface for pilot logging
- can interface to MQ
- for the moment kept in a separated repository
- consumers in DIRAC (MySQL DB ready) or maybe using ES
DIRACOS:
- Fixing the upload of tarballs to EOS
- Using http://diracos.web.cern.ch/diracos/
- maybe one day will converge to using the same URL of DIRAC tarballs
- gitlab-CI used -- in repo soon
- Release creation being fully automated with it
- Using http://diracos.web.cern.ch/diracos/
- DIRACOS v1r0 should be ready, tag soon (now for real)
Documentation
- new script (v7r0) for creating the documentation of the "dirac-*" commands, using the "--help" switch is in integration branch now
- We can put more docs in the docstrings, like done for dirac-install
- new howto section in PR (Chris)
- No updates to website
BOINC:
- NTR
DB12:
- NTR
tornado and other externals
- Chris tried M2Crypto from Simon, looks all good and promising
Release planning, tests and certification
Release planning:
- v6r20 series
- v6r20p26 probably the last patch of v6r20
- v6r21 series
- -pre3 ready
- v7r0 series
- Should install on DIRAC certification with:
- DIRAC v7r0-preX
- DIRACOS v1r0
- WebApp 4.0
- releases.cfg should be modified accordingly [done?]
- bashrc will need to be re-done, so a fresh installation is needed
- Instructions should go to https://github.com/DIRACGrid/DIRAC/wiki/DIRAC-v7r0
- All Jenkins tests should be updated
- Should install on DIRAC certification with:
Certification process:
- The DIRAC certification machine should be re-done from scratch, including the DB and all
- use CentOS7
- Started looking into Jenkins pipelines, looks good and powerful but not easy
