Things will change after we land bug 1231208, so let's disable this until then.

Jens, could you redirect this to someone who can take a look at it?

I believe comment 13 may have been in error due to confusion during a bulk triage session.

The check in question appears to be validating step 19.2.2.1 of https://fetch.spec.whatwg.org/#http-network-or-cache-fetch: "If storedResponse’s header list contains ETag, then append If-None-Match with its value to httpRequest’s header list."

Our logic to set this appears to live at https://searchfox.org/mozilla-central/rev/ebe492edacc75bb122a2b380e4cafcca3470864c/netwerk/protocol/http/nsHttpChannel.cpp#4515

Our current meta settings for the test at https://searchfox.org/mozilla-central/source/testing/web-platform/meta/service-workers/service-worker/update-no-cache-request-headers.https.html.ini make a number of failures okay, but it does seem like there is fundamentally an underlying intermittent-ness in the test.

The most likely problem is that the necko HTTP layer is returning a cached response when it should not. One notable thing is that the script file at https://searchfox.org/mozilla-central/source/testing/web-platform/tests/service-workers/service-worker/resources/test-request-headers-worker.py always returns a header of the form "ETag: etag". The semantics of "If-None-Match" are on the server to validate the Etag and return a 200 if it's changed. In this case, the server always returns the same ETag, but will also return a 200 because the server is a simple python script that doesn't validate the ETag at all. But it seems conceivable our network layer might have some optimization that assumes the server would obey the etag semantics. Alternately, there might be some edge case where the original request is still sufficiently alive from necko's perspective that we de-duplicate to the already-returned channel. Or alternately some kind of wasteful update() suppression is in effect. This definitely would benefit from an rr/pernosco trace.

Clearing Perry needinfo since Jan triaged appropriately and this is slightly lower than the set of SW e10s regressions that just happened. I'll quickly see if I can convince pernosco to generate a trace though.

Jens,
There have been 26 failures in the last 7 days on all platforms, could you please take a look?

Perry, please check if "Clearing Perry needinfo since Jan triaged appropriately and this is slightly lower than the set of SW e10s regressions that just happened." still applies or if you can move over to this soon.

Flags: needinfo?(jstutte) → needinfo?(perry)

I tried to figure out what could be wrong without being able to reproduce the failure and agree with Andrew's comment 35. In particular, it seems that all the setting of HTTP headers and consulting the cache is delegated to the networking layer, which is what the test is mostly concerned about. This is still a bug but I think it may make sense to change this to P3 because it doesn't appear to be a very breaking issue and is difficult to get more details on without a recording of a failure. So I'd say that "this is slightly lower than the set of SW e10s regressions" still applies.
