…acket loss The original implementation used a "last-write-wins" pattern that stored only the most recent datagram, causing approximately 75% packet loss in relay scenarios with multiple subscribers. This change: - Replaces `latest: Option<Datagram>` with `queue: VecDeque<Datagram>` - Adds configurable buffer size (MAX_DATAGRAM_BUFFER = 1024) - Implements proper multi-reader support using absolute position tracking - Each reader maintains `consumed_count` to track its position independently - Buffer overflow drops oldest datagrams while preserving reader positions This enables proper QUIC datagram relay for real-time media applications where packet throughput is critical.
- Add debug logging for SUBSCRIBE_OK handling to trace track_alias mapping - Fix potential deadlock by releasing subscribes lock before acquiring alias_map lock - Log alias_map state for troubleshooting datagram routing issues - Convert extension header logging from info to debug level
