* 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
* 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
* 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
* implement a memory-optimized time.Time replacement
* monotime: properly handle systems with bad timer resolution (Windows)
* monotime: simplify Since
This allows for more accurate packet number difference calculations,
which is especially important once we attempt to detect spurious loss
detection events.
* ackhandler: optimize memory layout of packet struct
The packet number can be derived from the position that this packet is
stored at in the packets slice in the sent packet history. There is no
need to store the packet number, saving 8 bytes per packet.
* ackhandler: avoid copying the packet struct
* update to Go 1.25, drop support for Go 1.23
* ci: update golangci-lint to v2.4.0
* use new go tool command for gomock / mockgen
* also update Go version used for oss-fuzz
* ackhandler: check for missing packets below reordering treshold
No functional change expected.
With the Acknowledgement Frequency extension, the reordering threshold
will become configurable. With this change, it will be easy to use the
peer-requested value instead of the predefined constant.
* improve documentation
* call HighestMissingUpTo in randomized test
* remove unused bool return value from sentPacketHandler.getPTOTimeAndSpace
* ackhandler: implement timer logic for path probing packets
Path probe packets are treated differently from regular packets: The new
path might have a vastly different RTT than the original path.
Path probe packets are declared lost 1s after they are sent. This value
can be reduced, once implement proper retransmission logic for lost path
probes.
* ackhandler: declare path probes lost on OnLossDetectionTimeout
The packet number generator for the application data packet number
space randomly skips packet numbers. We need to be careful to not
acknowledge a skipped packet when acknowledging a range of packets in
the sent packet handler tests.
* ackhandler: use slice instead of linked list to track received packets
* ackhandler: add benchmark test for received packet history
* ackhandler: use the slices package for slice manipulations
