Improve quic:stream_state_updated #374

Open rmarx opened 8 months ago

rmarx commented 8 months ago

As reported by @hlandau on the mailing list:

quic:stream_state_updated:

I think this needs to be clarified a little that an event logged here with both a stream_id field and a stream_side field is expressing a state for that component of the stream and from the perspective of the specified vantage point (also, what about the network vantage point?); whereas an event logged here with a stream_id field but no stream_side field is expressing a state for both stream components as a whole.

If my interpretation here is correct, I think it would also help to note that the valid values of StreamState depend on the value and presence of stream_side.

Specifically for the "network vantage point" aspect of the question: the intent was that a network observer would use "sending" vs "receiving" depending on which party opened the stream, but that indeed falls down when using bidi streams...

I think there is some overlap here with the stream_state values and their implied-ness for either one or both sides, but I think @LPardue has a better grasp on this than me.

@LPardue could use some input on this here :)
