The test was added here: https://hg.mozilla.org/mozilla-central/rev/90b53eda6606ea56e4db7538588420d1db8c3e0d
Christoph, wanna forward this to Benjamin (his account is disabled) to take a look and try to fix this on fission? Cause it's failing quite frequently: https://treeherder.mozilla.org/intermittent-failures.html#/bugdetails?startday=2019-09-07&endday=2019-09-14&tree=trunk&bug=1580643
Maybe the info here can be useful for him: https://wiki.mozilla.org/Project_Fission/Enabling_Tests_with_Fission

Pernosco link (with some points of interest in the notebook): https://pernos.co/debug/yojlep7WAe7seW_0sLU45A/index.html#f{m[Arqk,A4JE_,t[xg,CDQ_,f{e[Arqk,A4I6_,s{afyCPZxAA,bASE,oAsmjJw,uAr8LWA___

It looks like we're getting ChangeFrameRemoteness called on the child docshell, which tears it down and cancels the channel.

The channel in question here isn't that the one that initiated the process switch though, so when we receive DocumentChannelParent::RecvCancel, it's actually cancelling the load (of file_navigate_to.sjs for the current test).

I think we finish one subtest (based on the blocking events, or the load started event), and then we have a race between that subtest's process switch (for www.example.com), and the current subtests attempt to load file_navigate_to.sjs.

What should we do if we receive a request to tear down a docshell (because it's moved to another process), but by the time we get the message, we've already started loading a new document (and one that can be in-process)?

Nika, will any of your in-flight changes affect the ordering here?

Comment 12

[Matt Woodrow (:mattwoodrow)]

A possible plan here using DocumentChannel.

• Associate each DocumentChannelParent with the CanonicalBrowsingContext that it is loading for.
• If we get a new DocumentChannelParent for a CanonicalBrowsingContext, then cancel the load on the old one, and replace it.
• If we get a new DocumentChannelParent, and the CanonicalBrowsingContext is currently undergoing a process switch, or has done one (such that the PID for CBC doesn't match the OtherPid() of the DocumentChannelParent), then disconnect the associated DocumentChannelChild (set mDoingProcessSwitch, maybe SendCancelForProcessSwitch()).

That should let the new load from the docshell complete without being cancelled when the old docshell is torn down (since the new load is associated with the BrowsingContext which remains alive), and once we get OnStartRequest called for the new load, we'll go through the process switching logic to pick a destination process (which maybe be back to the old process).

This intermittent should have been resolved by bug 1586684, hence marking as a duplicate.
