* congestion: prevent uint64 overflow in pacer
This should never happen for bandwidths even remotely possible in
real-world scenarios, but it’s better to be safe.
* congestion: add a benchmark test for the pacer
* add a comment
* utils: initialize the {Smoothed, Latest, Min}RTT to 100ms
* utils: use time.Duration.Nanoseconds instead of uint64
No functional change expected.
* congestion: better check to avoid division by zero
This is needed for events such as recovery:loss_timer_updated, which
contain the timer expiration timestamp encoded as a difference from the
event time.
* qlog: implement a Trace and a Writer struct
* qlog: rename Trace to FileSeq
* split qlog trace writer and QUIC qlog events into separate packages
* use the new qlog.Recorder instead of the logging.ConnectionTracer
* qlog: use fork of encoding/json/jsontext instead of unmaintained gojay
* implement a minimal jsontext-compatible encoder
* qlogtext: improve fuzz test
* qlog: simplify JSON encoding error handling
* qlog: make use of jsontext.Bool
* ackhandler: implement a lost packet tracker
* logging: add ConnectionTracer.DetectedSpuriousLoss event
* ackhandler: detect spurious losses
* qlog: add support for logging spurious packet loss
* ackhandler: delete lost packets after detecting spurios loss
* guard against slice index underflow
* simplify timer resets
As of Go 1.23, timer resets work as expected, and there’s no need to
read a (potentially) stale value from the timer channel.
* don't save the last time
* track if blocked
* remove unblock after sendingScheduled
* fix unblock logic when sending
* don't use fallthrough
* track the blocking mode
* remove stale comment
* implement a memory-optimized time.Time replacement
* monotime: properly handle systems with bad timer resolution (Windows)
* monotime: simplify Since
* fix: return stream frames to pool on error paths
fixes potential memory leak where StreamFrames were not returned to
sync.Pool in error/cancellation paths.
root cause: frames are llocated via GetStreamFrame() but never returned
via PutBack() when streams enter terminal states without going through
normal OnAcked() cleanup.
fixed paths:
- CancelWrite(): return frames when reliableOffset == 0
- handleStopSendingFrame(): return frames on STOP_SENDING
- closeForShutdown(): return frames on connection shutdown
- OnLost(): return frame when stream reset with no data sent
* fix: clear slice before nil assignment, remove excessive tests
- add clear() call to properly release GC references per https://github.com/quic-go/quic-go/pull/5327#discussion_r2328451862
- remove excessive pool return tests per https://github.com/quic-go/quic-go/pull/5327#discussion_r2328453227
* do not allow use a closed transport
