Agenda

Tinderbox tests

• Status for tinderbox tests.
• kernel, gdi, and user handles leaks bug 397854

QA testing debug builds

• Status?

Status on found leak bugs

• Peter's cycle collection changes bug 379718
• RDF bug 383939
• plugin GetURL/PostURL leak bug 273025
• java leak bug 324796
• DNS shutdown leak bug 102229
• Get bugs filed on bad LeakingPages leaks.
• Other bad leaks?

Fixed bugs

• 10 leaks resolved since last week [1]
• Waiting approval for timer fix bug 330128, should take care of all(?) timer leaks.

To Do

• Get leak monitoring as an extension so that QA can test for leaks during litmus.
  • bug 394466 should fix OS leaks on linux.
  • AI:cbarrett Look into OS leaks on mac.
• Improve tinderbox tests.
  • Need to measure leaked GDI/user/kernel handles on windows (bug 397854). Possibly show on tinderbox.
  • bug 374822 Need a windows tinderbox with leak numbers since OS leaks are lower there.
  • AI:sicking Do leak monitoring while running tinderbox tests.
    • We do want to run trace-refcnt, trace-malloc on reftest/mochitest. (bug 397724)
    • Ideally we'd shut down between each testcase to identify where leaks happen. Mostly useful until we reach 0, but would help with regressions too.
  • Want a separate test suite that tests for assertions, crashes, leaks. (bug 397725)
• Important leak bugs:
  • bug 396368 Live connect leak the biggest one still not fixed.
  • bug 398292 tracks bugs that make it difficult to find other leaks through fuzzing.
  • bug 394052 Seems to be the only remaining window/document/docshell leak in Mochitests on at least some platforms, possibly all of them.
• Finding leaks in extensions
  • Need to solve license issue
• CoScripter Leak regression suite

Action Items

• AI:sicking Look into enabling trace-refcount, without the tracing part in nightlies.
• AI:cbarrett Look into OS leaks on Mac.

Meeting notes

• Tinderbox status
  • Window leak box up. Leaks 8 bytes refcnt leaks. 12.4k trace-malloc leaks.
  • No assertions, david to turn on fatal assertions.
  • Hopefully have unit-tests up next week. Will run on separate box.
• QA running leak tests for litmus
  • Problems running debug builds on non-dev machines.
    • Mac might be build config issue
    • Windows missing development dlls. Recommending installing msvc on test machines.
    • Something failing on linux.
  • Builds around 1.5Gb unpacked. 200-something megs packed.
    • This contains a whole /dist directory. Should be able to trim that down later once we have things working if we feel it's important.
• Fixed bugs
  • Sayrer has gone through a few old bugs and marked a few WFM.
• Leaking handles on windows
  • No testing done yet. Purify reports such leaks so we can use that for now.
