Comment 5

[Timothy Nikkel (:tnikkel)]

Things learned from these new failures:
failures are all on linux64-qr
failures are all in mochitest-fis-e10s

There seems to be two failure modes: one in mochitest-fis-e10s-1, one in mochitest-fis-e10s-13.

The mochitest-fis-e10s-1 failure is usually (always?) in docshell/test/mochitest/test_triggeringprincipal_location_seturi.html
This failure usually (always?) hits this warning

https://searchfox.org/mozilla-central/rev/6866d3a650c826f1cabd123663e84b95ee743701/docshell/base/nsDocShell.cpp#12240

and then this warning

https://searchfox.org/mozilla-central/rev/6866d3a650c826f1cabd123663e84b95ee743701/layout/base/nsDocumentViewer.cpp#2496

So this seems like the frame tree is in an unexpected state.

The mochitest-fis-e10s-13 failure is usually (always?) in js/xpconnect/tests/mochitest/test_bug802557.html
Neither of the above warnings are printed in the log ever. So this seems like it could be a different failure mode.

So this seems like the frame tree is in an unexpected state.

Those warnings trigger in the passing case too. But still likely a clue. Perhaps we change frame types without an invalidation and that causes it?

Comment 15

[Timothy Nikkel (:tnikkel)]

All the failures this year have been right after loading layout/reftests/bugs/474472-1.html.

Comment 16

[Timothy Nikkel (:tnikkel)]

This started showing up again as bug 1579621 (in opt builds, so we don't hit the assert in the bug title). It showed up in parser/htmlparser/tests/crashtests/515533-1.html and layout/reftests/bugs/474472-1.html on one of my try pushes. I created 100 different copies of those tests and ran it on try, reproduces almost every time. And even more so it reproduces on my local linux box.

parser/htmlparser/tests/crashtests/515533-1.html is pretty simple, it contains an iframe to a local file (so it's a same process iframe). The document in the iframe has an inline script that does

window.location.replace("data:text/plain,");

since crashtests have the pref browser.tabs.remote.dataUriInDefaultWebProcess set (to get more testing of fission) this makes the iframe now in a different process from it's parent.

When the bug happens we create the retained nsDisplaySubDocument before the process change, the document inside the iframe has a presshell, and importantly, it does not yet have a root frame. The remoteness change happens on the iframe, ResetFrameLoader is called on the subdocument frame to remove the old frame loader. So now the subdocument frame can't find a presshell (either via views or the frameloader).

The reason the iframe not having a root frame when the nsDisplaySubDocument is created is important because if we had a root frame then the root frame would be the mFrame of the nsDisplaySubDocument and when the root frame got destroyed for the remoteness change that make sure that the nsDisplaySubDocument cannot be re-used. The nsSubDocumentFrame sticks around though, so the nsDisplaySubDocument doesn't think anything changed.

Attachment: Bug 1582653. Need to clear any associated display items of a nsSubDocumentFrame when the frame loader changes. r?mattwoodrow

parser/htmlparser/tests/crashtests/515533-1.html most cleanly creates this crash if you repeat it many times.

It contains an iframe to a local file (so it's a same process iframe). The document in the iframe has an inline script that does

window.location.replace("data:text/plain,");

since crashtests have the pref browser.tabs.remote.dataUriInDefaultWebProcess set (to get more testing of fission) this makes the iframe now in a different process from it's parent.

When the bug happens we create the retained nsDisplaySubDocument before the process change, the document inside the iframe has a presshell, and importantly, it does not yet have a root frame. Then the remoteness change happens on the iframe, ResetFrameLoader is called on the nsSubDocumentFrame to remove the old frame loader. So now the nsSubDocumentFrame can't find a presshell (either via views or the frameloader).

The reason that the document in the iframe not having a root frame when the nsDisplaySubDocument is created is important is because if we had a root frame then the root frame would be the mFrame of the nsDisplaySubDocument and when the root frame got destroyed for the remoteness change that frame destruction would make sure that the nsDisplaySubDocument cannot be re-used.
