Bug 1525640 - Pass TRR status from sockettransport to channel r=dragana

Bug 1525640 - Add nsIHttpChannelInternal.isResolvedByTRR r=dragana
(deleted), text/x-phabricator-request
Details

This would be useful when gathering telemetry/doing TRR experiments.
Right now we have nsIHttpChannelInternal.trr, but that only specifies if that channel is used to perform DoH requests.

Whiteboard: [necko-triaged] → [necko-triaged][trr]

We ended up finding this information another way, so closing.

Turns out this would still be useful, for bug 1542331 for example.

TODO: make sure it works in the child channel

TODO: make sure it works in the child channel

I manually checked that it works, but I still need to write a proper unit test for this.

I still find it very unlikely that this patch is causing the leaks.
I see the orange count in bug 1515057 is still quite high, even without the patch. But in any case I'll do some more testing on try. Maybe there is some subtle way this is breaking things.

Flags: needinfo?(valentin.gosu)

So, I figured I'd try this locally, using the instructions from bug 1515057 comment 44

I ran the test with my latest pull from m-c on linux and I was able to reproduce it immediately, without applying my patch.

Interestingly, if I run the wpt in headless mode, the leak doesn't happen.
