  • ACS website: Still not published. Low priority
  • 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
    • 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

      • 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.
