Bug 78445 – Web Inspector: include failed and canceled in FrameResourceTree

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Timothy Hatcher]

The protocol should include some more info about resources in FrameResourceTree. Like failed, canceld, loading, resource size and request identifier.

At this moment, we only add methods to the protocol that are used by the front-end. This way we can guarantee it is useful and we can test it. Are you planning on using this data in the front-end or is there alternative front-end it is for? I am fine with changing the rules to the "we can expose functionality not used by the inspector front-end", but we need to make sure these methods are tested.

These are going to be wrong for the ports that have network stack responsible for encoding.

I am not sure how relevant this is given the asynchronous nature of the front-end - backend interaction. There is no guarantee that it is still "true" at the moment message is received.

Do we have other tests that just test the protocol and not the front-end?

I'm fine just having one property, "size",  and using encodedSize.

You would also observe the Network.loadingFailed and Network.loadingFinished events. You would have those events queued up to make it false.

I wonder if this could result in flakiness. Do you know if the order cached resources are created and persisted is fixed?

This is indeed causing flakiness.  We're getting a different order on the 3 bots that have run this test so far.  This is also why the ews bot failed.

[Timothy Hatcher]

Sigh. I'm going to disable the test. I want to keep the change.

[Timothy Hatcher]

Removed the test in r107720 and filed bug 78621 about making a better test.

[Timothy Hatcher]

Fixed in r107714.
