bd29c529a8 feat: add WebSocket frame reader state machine 2026-02-23 04:51:54 -05:00

1a1aa9d642 fix: use byte-length for close message truncation, add exception-safe disposal 
- CreateCloseMessage now operates on UTF-8 byte length (matching Go's
  len(body) behavior) instead of character length, with proper UTF-8
  boundary detection during truncation
- WsCompression.Compress now uses try/finally for exception-safe disposal
  of DeflateStream and MemoryStream

d49bc5b0d7 feat: add WebSocket permessage-deflate compression 
Implement WsCompression with Compress/Decompress methods per RFC 7692.
Key .NET adaptation: Flush() without Dispose() on DeflateStream to produce
the correct sync flush marker that can be stripped and re-appended.

Port WsConstants from golang/nats-server/server/websocket.go lines 41-106.
Includes opcodes, frame header bits, close status codes, compression
constants, header names, path routing, and the WsClientKind enum.

dab8004d6b feat: cache INFO serialization — build once at startup instead of per-connection 
Avoids re-serializing the same ServerInfo JSON on every new connection. The
cache is rebuilt when the ephemeral port is resolved. Connections that carry a
per-connection nonce (NKey auth) continue to serialize individually so the nonce
is included correctly.

0ec5583422 fix: address code quality review findings for batch 1 
- SubjectsCollide: split tokens once upfront instead of O(n²) TokenAt calls
- NatsHeaderParser: manual digit accumulation avoids string allocation and overflow
- NatsHeaders: use IReadOnlyDictionary for Headers, immutable Invalid sentinel
- PermissionLruCache: add missing Count property

3941c85e76 Merge branch 'feature/core-lifecycle' into main 
Reconcile close reason tracking: feature branch's MarkClosed() and
ShouldSkipFlush/FlushAndCloseAsync now use main's ClientClosedReason
enum. ClosedState enum retained for forward compatibility.

2fb14821e0 feat: add no-responders CONNECT validation and tests 
Reject connections that send no_responders:true without headers:true,
since the 503 HMSG response requires header support. Add three tests:
connection rejection, acceptance with headers, and 503 delivery flow.

04305447f9 feat: implement verbose mode (+OK after commands) 
When a client sends CONNECT {"verbose":true}, the server now responds
with +OK\r\n after successfully processing CONNECT, PING, SUB, UNSUB,
and PUB/HPUB commands, matching the Go NATS server behavior.

bce793fd42 perf: batch stat increments per read cycle in ProcessCommandsAsync 
Accumulate InMsgs/InBytes locally per ReadAsync cycle and flush once,
reducing from 4 Interlocked operations per published message to 2 per
read cycle. This matches the Go server's approach of batching stats.

c522ce99f5 feat: add delivery tracking and no-responders 503 support to ProcessMessage 
When a PUB with a reply-to subject has no matching subscribers and the
sender opted into no_responders, send a 503 HMSG back on the reply
subject so request-reply callers can fail fast instead of timing out.
