Action Items from previous meeting:

• Make Python 3 Migration page public: ACS Python 3 port

2019 Planning:

• ACS website: Still not published. Low priority
  • Joseph Schwarz has not been able to work on this yet.
• Upgrade JAR libraries to Java 11 compatible versions (Hibernate 5 is the main one)
  • Available since 2019FEB.
  • Applications using hibernate may require different levels of attention depending on what parts of the library they use.
• Port ACS to Java 11
  • Core of the porting started with 2019APR.
  • Upgrade of libraries found in run-time, compilation issues and other fixes/improvements for Java 11 done as part of 2019JUN.
  • Due to incompatibility between the changes and the Java 8 version, these modifications are not available on master branch. They will be merged after ALMA Go/NoGo decision on July 26th.
  • Merge to the master is expected somewhere between August and September, so it would not be available as part of 2019AUG, but 2019OCT if the Go/NoGo decission is positive.
  • If anyone is interested in this, we could provide a Java 11 compatible branch at some point after June 21st (This is when the verification of 2019JUN finishes).
• Port ACS to Python 3
  • Refactor acsMakefile
  • Bug-fixing
  • • We have a complicated schedule between the Java 11, new ACS Makefile and other key ALMA deliverable.
    • We're aiming to have this before 2019DEC.
      • We mentioned 2020JAN, but that is an ALMASW-only deliverable (ACS only make releases on even months).
  • Refactor ACS Makefile
    • First roll-out scheduled with 2019JUN.
    • It will handle dependencies calculation among modules.
    • Should improve performance on multi-cpu/core machines.
    • It will coexist with current Makefile for at least a year.
  • Bug-fixing
    • False ACE/TAO CORBA Timeouts

      • Jira
        server ICT columns key,summary,type,created,updated,due,assignee,reporter,priority,status,resolution serverId 451c03fa-a384-3e36-95b3-3ef4dae081ba key ICT-12886

      • Share bug-fix with TAO community or even create the pull-request (ACE+TAO github).
    • Notification Channel
      • Problems with Notification Channel/Service after it has been left up running for weeks.
      • Check if it might be related with problems seen at ALMA.
      • Check memory usage of the Notification Service process when the problem happens to see if this may be a slow consumer generating issues.

  Other institutions plans and proposed topics

  • Integrating TAT with Jenkins
    • Problems parsing the output from TAT tasks.
    • ALMA to provide the parsing script being used here.
      • It doesn't support multi-level analysis at this point for nested groups.

  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
    
    • It will be separated from the ALMA Bitbucket server due to licensing restrictions.
    • This would give more freedom to create users and other actions on the community server.
  • RedHat 8
    • ACS should be compatible with RH 8.x considering the efforts that have been made so far to work with newer OS and technologies.
      
    • This won't be tested until appropriate environments for testing are available. Either:
      • ALMA provides official RH 8.x support
      • CentOS 8.x docker images are available
