Joseph Doherty 88b1391ef0 feat: port session 07 — Protocol Parser, Auth extras (TPM/certidp/certstore), Internal utilities & data structures
Session 07 scope (5 features, 17 tests, ~1165 Go LOC):
- Protocol/ParserTypes.cs: ParserState enum (79 states), PublishArgument, ParseContext
- Protocol/IProtocolHandler.cs: handler interface decoupling parser from client
- Protocol/ProtocolParser.cs: Parse(), ProtoSnippet(), OverMaxControlLineLimit(),
  ProcessPub/HeaderPub/RoutedMsgArgs/RoutedHeaderMsgArgs, ClonePubArg(), GetHeader()
- tests/Protocol/ProtocolParserTests.cs: 17 tests via TestProtocolHandler stub

Auth extras from session 06 (committed separately):
- Auth/TpmKeyProvider.cs, Auth/CertificateIdentityProvider/, Auth/CertificateStore/

Internal utilities & data structures (session 06 overflow):
- Internal/AccessTimeService.cs, ElasticPointer.cs, SystemMemory.cs, ProcessStatsProvider.cs
- Internal/DataStructures/GenericSublist.cs, HashWheel.cs
- Internal/DataStructures/SubjectTree.cs, SubjectTreeNode.cs, SubjectTreeParts.cs

All 461 tests pass (460 unit + 1 integration). DB updated for features 2588-2592 and tests 2598-2614.

Session 16: Gateways

Summary

Gateway connections — inter-cluster message routing. Gateways enable NATS super-clusters where messages flow between independent clusters.

Scope

Go File Features Feature IDs Go LOC
server/gateway.go 91 12631353 2,816

.NET Classes

  • GatewayHandler — gateway connection management
  • GatewayCfg — gateway configuration
  • ServerGateway — per-server gateway state
  • GatewayInterestMode — interest/optimistic mode tracking
  • GwReplyMapping — reply-to subject mapping for gateways
  • ClientConnection (partial — gateway-specific methods)

Dependencies

  • Session 01 (Foundation Types)
  • Session 07 (Protocol Parser)
  • Session 08 (Client Connection)
  • Session 09 (Server Core Part 1)
  • Session 11 (Accounts — for interest propagation)
  • Session 14 (Routes)

.NET Target Location

  • dotnet/src/ZB.MOM.NatsNet.Server/Gateway/

Notes

  • Gateway protocol has optimistic and interest-only modes
  • Account-aware interest propagation is complex
  • 88 tests — thorough coverage of gateway scenarios
