Igor Postelnik 2c480a72db TUN-6280: Don't wrap qlog connection tracer for gatethering QUIC metrics since we're not writing qlog files. 2022-05-24 16:59:03 -05:00

Nuno Diegues ed2bac026d TUN-5621: Correctly manage QUIC stream closing
Until this PR, we were naively closing the quic.Stream whenever
the callstack for handling the request (HTTP or TCP) finished.
However, our proxy handler may still be reading or writing from
the quic.Stream at that point, because we return the callstack if
either side finishes, but not necessarily both.

This is a problem for quic-go library because quic.Stream#Close
cannot be called concurrently with quic.Stream#Write

Furthermore, we also noticed that quic.Stream#Close does nothing
to do receiving stream (since, underneath, quic.Stream has 2 streams,
1 for each direction), thus leaking memory, as explained in:
https://github.com/lucas-clemente/quic-go/issues/3322

This PR addresses both problems by wrapping the quic.Stream that
is passed down to the proxying logic and handle all these concerns.
