Bumps quic-go to v0.59.1 (chungthuang fork rebased from upstream v0.45 onto
v0.59.1). Upstream removed the `logging` package and replaced its
callback-based ConnectionTracer with the structured `qlog`/`qlogwriter` event
API, which required migrating cloudflared's QUIC metrics collection.
Migrations:
- quic/tracing.go: connTracer no longer fills a logging.ConnectionTracer
callback struct. It implements qlogwriter.Trace + qlogwriter.Recorder and
dispatches qlog events (PacketSent, PacketReceived, MetricsUpdated, ...) to
the collector through RecordEvent. NewClientTracer now returns a function
compatible with quic.Config.Tracer.
- quic/metrics.go: collector methods take qlog types (qlog.Frame,
qlog.PacketType, qlog.MetricsUpdated, ...) and plain int64 in place of the
removed logging.ByteCount/Frame/RTTStats/TransportParameters.
- quic/conversion.go: PacketType, PacketDropReason and PacketLossReason are
strings upstream rather than numeric iotas, so the converters become
pass-through allowlists. CongestionState is also a string;
congestionStateToFloat maps it back to the numeric gauge values cloudflared
exports.
- quic.Connection/quic.Stream became *quic.Conn/*quic.Stream; updated
ConnWithCloser, SafeStreamCloser and the connection package accordingly.
Tests and generated mocks (mocks/mock_quic_connection.go) were adapted to
the new pointer-based API.
Closes TUN-10557
The lucas-clemente/quic-go package moved namespaces and our branch
went stale, this new fork provides support for the new quic-go repo
and applies the max datagram frame size change.
Until the max datagram frame size support gets upstreamed into quic-go,
this can be used to unblock go 1.20 support as the old
lucas-clemente/quic-go will not get go 1.20 support.
