Minutes

Gutenberg test running against Firefox

• Alex is finally able to run the first Gutenberg test up to completion!
  • Had to reverse engineer the precise order of CDP events, which has proven challenging
  • ato thinks it makes sense to focus on ensuring it is cross-browser compatible, otherwise end users will find it hard to relate CDP events to web platform primitives and there will be a difference in behaviour between Chrome and Firefox
  • Alxo also submitted patches for:
    • Implement Page.frameNavigated (bug 1543095)
    • Implement Runtime.executionContextCreated and Runtime.executionContextDestroyed (bug 1543098)
      • A followup, though not mandatory for WordPress is also to fire Runtime.executionContextDestroyed when the tab closes (bug 1547198)
  • Other CDP methods to follow up on:
    • Implement Runtime.evaluate and Runtime.callFunctionOn (bug 1543099)
    • Implement Page.reload (bug 1544445)
• More memory leaks reported for browser-chrome tests
  • We disabled browser_cdp.js last week because it was perma-failing the leakcheck, and we thought the memory leak was limied to this one test
  • Over the weekend more intermittent leaks cropped up in other tests:
    • bug 1547303
    • bug 1546850
  • We will proceed with disabling the browser-chrome tests on debug builds
  • We suspect there’s a memory leak related to nsIServerSocket, but it’s not a priority to fix it right now
  • Memory leaks obviously also affect optimised builds, but since we’re not doing refcounting we don’t notice
