Minutes (Main Points Only)


  • The July casapy-stable has been published: casapy-stable r25701. The August casapy-stable code commit deadline is imminent (Aug 15th).
  • Latest casapy-test published: casapy-test r25953 (published on Friday 9th).
    • Known Issue: If both rpms and a tar casapy-stable are installed on the same RHEL 5.x system, and their versions do not match, you will see the failure described in CAS-5445 when starting CASA from the tar. You will not see this issue when starting casa from the rpms.

Current Number of CASA Jira tickets with "Ready To Test" status (including EA, EU, JAO, Software-only tickets): 61.

PART 1: Items To Be Covered During The Meeting

Ready to Close Items

N.B. The following items will not be worked through one-by-one. Attendees should identify any items they wish to keep open during the meeting.

  • CAS-5375 (Aug): calmode='otf' or 'otfraster' have a bug in sdcal2. Minor SD bugfix item. Currently RTT.

A fix had been put in and tested by Steve. He has provided feedback. Ticket is currently Open, assigned to Jeff. Might already be testable/tested?
  • CAS-5084 (May): Testing multi-term support in pclean. Currently Open, recently reassigned to Kumar to address some reported issues. Lots of feedback supplied by Kristina and Claire.

Other Blockers

  • CAS-4946 Crash on Mac OS X when virtual model requested. BLOCKER. Recently re-checked by Nathan, and it now sounds as if this affects Mac OS X 10.6, but not 10.7 or 10.8.
