Multicore Debug Workgroup Minutes of Meetings

July 8th, 2014

Attendees

  1. Marc Dumais (Ericsson)
  2. Xavier Raynaud (Kalray)
  3. Mikhail Khodjaiants (Mentor)
  4. Jeff Johnston (RedHat)
  5. William Riley (Renesas)
  6. Marc Khouzam (Ericsson)

Minutes

  • Luna release
    • Coordinated testing was valuable and helped find bugs that would have gone unnoticed
    • Coordinated testing only required 1 to 2 hours of the involved people. Good return on investment
  • Launch bar
    • No update
  • Debug tests on Hudson
    • Debug tests with latest GDB run as part of CDT's master nightly build and part of every Gerrit review build
    • Nighlty jobs added to run tests with GDB version 6.6 to latest. Not all tests pass yet and should be eventually cleaned up or some disabled to get a green light
    • Nightly job to run tests using GDB built from its own master branch and another for GDB's maintenance branch. This allows us to notify the GDB community of regressions that affect CDT before the GDB is released.
  • New UI
    • No update
  • Multi-terminate/disconnect
    • Elegant solution posted and reviewed
    • JUnit tests are harder to write because we have to somehow check that we disconnected or terminated processes
    • Manual tests could be added instead in the test document
  • Pin & Clone for Visualizer
    • Patch available to add a clone button to visualizer. Waiting for review.
    • Will allow to have multiple visualizer views which work with different filters
    • Pin will be worked on to provide even better value for multiple visualizer views
  • Stand-alone
    • -help now supported
    • params after executable are no longer swallowed by eclipse
    • vmargs now supported
    • better path support for binary including support for PATH variable
    • man page to be available
    • handling installations that use dropins, don't mix RPM install with p2 install
