Meeting 2019-09-19

Round table:

• have an IPC "pipe" with an integrated flow control to reuse?
  • currently used between HttpChannelParent/Child
  • probably used for new actors on the socket process
  • TCPSocket (used to be dom exposed, now it's used by webrtc as the main tool for connection establishment when proxying - in progress)
• DevTools request: bug 1556451 (http-on-cancel-request)
• Bug 1581599 - Some HTTP/2 responses are incorrectly marked as weakly framed
• multiple network change events on Windows, none on Linux
• Intern document & hackerrank questions

Intern document & hackerrank questions

mayhemer

• secure proxy phase 2 updates

done:

• secure proxy crashes: only the one known in 69(.0.0), 47 crashes since FPN release = <<10 a day
• most crash bugs I'm assigned to
  • using a build with forced non-t-s refcnt checking for daily browsing: no crashes in 4 days :(
  • (in progress) 1582228 - Detect evil concurrent access on RefPtr, nsCOMPtr et al objects draft of a runtime checker for concurrent re-assignment of ref/com/smartptrs; not that easy to do, lot of assumptions about RefPtr being like a "raw ptr", but with some more work added into this I can see some possible way of doing it, see the bug
  • 1546191 - Crash in [@ nsCORSListenerProxy::OnStopRequest] duplicate of 1529911, uplifted to esr68 to fix fennec
  • 1536772 - Intermittent netwerk/test/crashtests/785753-1.html | application crashed [...] gave up on this, no longer able to repro :( rate is small
  • 1580921 - Improve thread-safety checks on mozilla::WeakPtr no crashes found...
  • 1580182 - Allow mozilla::SupportsWeakPtr be on base classes as well. landed, not used
• figure possible throttling via Windows Filtering Platform (successor of LSP)
  • there is a way but we won't use it, want own non-root solution
  • we have a plan for throttling

in progress:

• BT -> OKR
• Necko classes and properties · mayhemer/logan Wiki incrementally documenting the properties you can filter and search by in logan

next:

• open alt data input stream async
• appcache sanitization for thumbnail container (mt io)
• 1523367 - Support equivalent of Chromium's --host-resolver-rules in Necko
• 4 or 5 P1 DoH bugs
