Add FrameworkReference to Microsoft.AspNetCore.App to enable Kestrel
Minimal APIs for the monitoring HTTP server. Remove the now-redundant
Microsoft.Extensions.Logging.Abstractions PackageReference (it is
included transitively via the framework reference).
Add monitoring config properties (MonitorPort, MonitorHost,
MonitorBasePath, MonitorHttpsPort) and TLS config properties (TlsCert,
TlsKey, TlsCaCert, TlsVerify, TlsHandshakeFirst, etc.) to NatsOptions.
Add TlsRequired, TlsVerify, and TlsAvailable fields to ServerInfo so
the server can advertise TLS capability in the INFO protocol message.
Move max payload validation from the parser to ProcessPubAsync so the
server sends -ERR 'Maximum Payload Violation' and closes the connection
(matching Go reference client.go:2442). In pedantic mode, reject PUB
with wildcard subjects via -ERR 'Invalid Publish Subject' (client.go:2869).
Add disposed guard to SubList.Remove to prevent crash during shutdown.
Covers /varz, /connz endpoints via Kestrel Minimal APIs,
full TLS support with four modes (none/required/first/mixed),
cert pinning, rate limiting, and testing strategy.
Four tasks: -ERR infrastructure, MaxConnections enforcement,
pedantic subject validation + max payload on PUB, PING keepalive.
Full TDD steps with exact code and commands.
Replace empty catch blocks with meaningful log statements in NatsServer,
NatsClient, and Program. Add WaitForReadyAsync() to NatsServer for
deterministic server startup. Replace Task.Delay/Thread.Sleep in tests
with PING/PONG protocol flush and SubscribeCoreAsync for reliable
subscription synchronization.
Remove template UnitTest1.cs placeholder. Add actual project structure,
run commands for the NATS server host, and update test command examples
to reference the real project paths.
Validates the server against the official NATS .NET client library with
tests for basic pub/sub, wildcard (* and >) matching, fan-out to
multiple subscribers, and PING/PONG keepalive. All 5 tests pass without
requiring any server changes.
Add NatsParser that reads NATS protocol commands from
ReadOnlySequence<byte>. Identifies commands by first 2 bytes using
case-insensitive bit masking. Handles PUB/HPUB payload reading with
stateful _awaitingPayload for split-packet scenarios. Uses Span<Range>
for zero-allocation argument splitting and ParseSize for ASCII decimal
parsing. Includes CommandType enum, ParsedCommand struct, and
ProtocolViolationException.
14 tests covering PING, PONG, CONNECT, INFO, SUB (with/without queue),
UNSUB (with/without max), PUB (with/without reply, zero payload),
HPUB, multiple commands, and case insensitivity.
10 tasks from scaffolding through integration tests, each with
TDD steps, exact file paths, and complete code. Bottom-up order:
SubList → Parser → Client → Server → Integration.
