Action Items from previous meeting:
- Share with ACE/TAO the bugfix for CORBA false timeouts: https://github.com/DOCGroup/ACE_TAO/issues/1053
- Share TAT parsing utility/scripts
- ACS/LGPL/acsBUILD/src/tat_parser.py
- Parse the test.log file generated from the 'make test' directive:
- Follow up ACS Website tasks
Updates since last Meeting:
- Port ACS to Java 11
- ACS and the ALMA SW has been successfully ported to Java 11
- Acceptance of ALMA SW using Java 11 is already undergoing
- Port ACS to Python 3
- ACS was partially ported to Python 3 with 2019OCT release
- Provides both Python 2 and 3 interpreters using 'pyenv'
- Versions 2.7.16 and 3.6.9 are currently provided by ACS
- Several bug-fixes in 2019DEC and 2020FEB
- Initial tests show that it only works for clients
- More bug-fixes and port of containers done in 2020APR
- ~2% difference in tests results between Python 2 and 3
- Mostly, the difference is in the output due to the interpreter version,
- We do not discard some small pending compatibility changes
- Mostly, changing between Python 2 and 3 means only to execute 'pyenv':
- 'pyenv 2.7.16'
- 'pyenv 3.6.9'
- Only exception is acstime, which needs to be recompiled due to swig code being compiled and linked against only one Python header/library file
- ACS Changes
- Enabled ACE/TAO iterators for CORBA types
- ACS Container Daemon capability to create stacktraces and/or heap/core dumps
- Works for Python, Java and C++
- PyXB Upgrade to 1.2.6 (Latest)
- Affects code generated using pyxbgen (XSDBIND Makefile declarations)
- Mostly the code is compatible:
- XSD sequence was changed from list ([...]) to an interable (_PluralBinding class)
- In most cases they're compatible, but under some specific usage it may not
- Stabilization of TAT module tests
- There were around 40% of the tests failing. This has been lowered to around 5%, but we want to aim to at least around 1-3%
- Refactor of ACS Makefile
- The refactor of ACS Makefile is currently stalled in favor of the Python 3 porting and tests stabilization
- RedHat 8 / CentOS 8
- Start investigation about ACS/Common and RH/CentOS 8 compatibility
- Bug-fixing
- Fix memory leak in Components Smart Ptr class
- enumpropROImpl and enumpropRWImpl are initializing the BACI property with an uninitialized default value
- Overriding the value of in env. defined CPU in the acs makefile
- Behavior of retrieving non-existent loggers in Java, C++ and Python is different
- archive_delta and archive_delta_percent don't work if pollingInterval=0
- ACS 2020APR was finished today and internal pre-release published
- Will reach the community in around 2 months
2020 Planning:
- ACS website: Still not published. Low priority
- Port ACS to Python 3
- 2020AUG is expected to be a Python 3 only version of ACS, but it may still be compatible with Python 2 for a couple of releases afterwards
- This only means that no further efforts would be made to make it compatible with Python 2
- ACS Tests stabilization (Probably by finished with 2020JUN release)
- Python 3 bug-fixing
- Refactor ACS Makefile
- Core of the work is already done
- Need to re-schedule the pending tasks
- Re-design the notification service
- This is a tentative work to provide an alternative for the current notification service
- We're in the planning phase of this project
Other institutions plans and proposed topics
Any other business?
- Confluence
- This is the official content collaboration tool now used at ALMA.
- ACS space is open to public, but editing is limited to registered users.
- People interested in editing should let us know by e-mail either to acs-discuss or directly to Tomas Staig.
- ACS Community Bitbucket server has been separated from the ALMA Bitbucket server
