CASA 4.2.1 Patch Plan

Status

RJS 5/12/14:

• CASA 4.2.1 released publicly on OSX and RHEL.

RJS 4/30/14:

• OSX
  • Viewer debugging and testing in developer environments has concluded. Currently testing a pre-release package on 10.7 and 10.8.
  • Five outstanding regression test failures to diagnose and resolve. See CAS-6357.

RJS 4/11/14:

• RHEL:
  • RHEL release of CASA 4.2.1 is ready for use and is in the process of being made available on the NRAO network.
• OSX:
  • Library linking issues reported on 3/31/14 have been resolved.
  • User testing of the package has revealed instabilities in the viewer. Further development effort will be required to debug.
  • Another round of pre-release testing will be required after the viewer development work. This has been reflected on the schedule below.

RJS 3/31/14:

• Work is in progress to release both RHEL and OSX CASA 4.2.1 packages. Work that has been completed or started is reflected in the Gantt chart under the '% Complete" column.
  • The fixes from the 4.2.0 branch as well as the fix for CAS-6037 have been merged into this branch.
  • Work is currently focused on the iterative build and package acceptance test cycle for both RHEL and OSX.
  • OSX debugging is blocked by a library linking issue between CASA, CUPS and another 3rd party library. This is currently causing CASA to crash on OSX 10.7.
• A "Risk" column has been added to the Gantt chart to provide an indication of the schedule risk associated with each task.
  • It is especially hard to quantify the effort/time required for OSX debugging ('Iterative Building & Package Acceptance Test Cycle for OSX"). If this iterative cycle can be completed by 4/11/14, the package should be available for users at the Imaging Synthesis Workshop. Should this work extend beyond 4/11/14, providing this package in time is increasingly difficult due to the limited contingency time available in the 4.2.1 OSX release schedule.

Goal

To support the Synthesis Imaging Workshop on 13-20 May, 2014.

Requested Patch Features

Based on input from Steve Myers, Crystal Brogan and Adam Leroy:

• High-priority bug fix to the Viewer
  • CAS-6037: Cursors dock widget remains blank when an image is opened in one particular way.

Other Requirements

• Timing:
  • Be available for the Synthesis Imaging Workshop on 13-20 May, 2014.
    • It is a goal to have the package released on RHEL and OSX 1 month before workshop for installation lead-time and other preparatory tasks.
• Testing
  • Typical package acceptance testing for a CASA deliverable.
  • User testing for OSX Package.

Implementation Plan

• Abandon releasing 4.2.0 on OSX.
• Setup branch and merge fix for CAS-6037.
• Building, testing, debugging and packaging to release 4.2.1 on OSX
• Building, testing, debugging and packaging to release 4.2.1 on RHEL
• Typical package acceptance for both RHEL and OSX.
• User acceptance testing for OSX only (RHEL 4.2.0 user testing is sufficient).

Schedule
