Build, Release, Testing

  • CASA 4.2.1 Release on OSX
    • Pre-release testing results by Juergen.
    • Plotms and other applications seems to work well, but viewer is somewhat unstable.
    • Punch list of automated tests to be resolved. Scott identifying which tests can be run headless. Will ask for assistance from team once they are identified.
    • Darrell & Susan on Viewer. OSX 10.7 machine to be given to Susan for direct debugging.
    • Darrell & Susan would like to merge the trunk fixes to the branch. Some crashes and issues may already be addressed in the trunk. Some new issues identified may also be cross-platform.
      • Will need to merge trunk changes from trunk to both 4.2.1 and 4.2.2.
      • Given codebase change, OSX 4.2.1 should likely have a additional decimal to differentiate from the RHEL 4.2.1 release.
    • Additional testing by Juergen (Dev. environment & 10.8) to focus debugging effort.
    • CASA 4.2.1. Plan
  • CASA 4.2.1 Release on EL
    • Released internally end of last week. Will be available for the summer school.
  • CASA 4.2.2
    • On hold in preference on 4.2.1 and 4.3 test package. (1 week delay)
  • CASA 4.3 Test Packages
    • Test package this week.

Architecture

    • April 17th - Lindsey - Pipelines
  • Modern compiler and C++ 11
  • Environmental variables.
  • CASA Document Repository.

Development

  • 4.2.2
  • 4.3
    • Schedule
      • Trying to rationalize the releases to match ALMA October cycles and EVLA reconfigurations.
  • Weekly staff reports - (halt practice?)
  • "asynch=T"
    • Jeff interested in identifying objections to removing this feature.
    • Susan does use it in plotms.
    • No objections from pipeline or users who have been consulted.
    • Conclusion: Remove it. Implement the change for 4.3 or later (no sooner). Shinosuke to evaluate the plan for removing it.
