so the real question here is why can't we find the push cache on e10s for this test case? (which is why we reset the push).. Nick I think you recently worked on another bug that manifested like that..

Also, uncompressanddiscard() called from recvpushpromise() needs to learn that its from a push so it can set the "isPush" bool to the decoder correctly - which would prevent us from throwing this error even if we are refusing the push stream for some reason.

Attached patch patchSplinter Review
Pat - thanks for doing the heavy lifting for me to figure out the fix for the big problem (site never loads). This patch takes care of that. Let's leave this bug for that problem, and I'll clone this to a second bug to investigate the push cache not found issue - that issue isn't a show-stopper, just sub-optimal.

This appears to affect both e10s and non-e10s enabled browsers, so we should probably at least think about uplifting further than 45.

Approval Request Comment
[Feature/regressing bug #]: Bug 1136727
[User impact if declined]: Some sites (at least may not load
[Describe test coverage new/current, TreeHerder]: on m-c
[Risks and why]: Low risk - this was an oversight in the original patch, and just (appropriately) disables certain validation paths for headers received in h2 pushes that are being thrown away.
[String/UUID change made/needed]: none

Jonathan, could you please verify this issue is fixed as expected on a latest Nightly build? Thanks!

Uplifting to Aurora45. It's unclear how many sites are affected, and given that this has been around since 42, I am leaning towards rejecting this for Beta44. On win8 44.0b6, I tried STR and was able to load

Tracking since this was a regression, though it's already fixed.
