Port 36 Go-parity tests covering redelivery, NAK, push consumer
heartbeats, interest retention with wildcards, ack-all with large
first seq, deliver last-per-subject, work-in-progress acks, flow
control stall, KV operations, multi-account isolation, and subject
transforms.
Go refs: TestJetStreamRedeliverAndLateAck, TestJetStreamInterestRetention,
TestJetStreamKVDelete, TestJetStreamMultipleAccountsBasics, and 23+ more.
Port Go client_test.go and server_test.go tests. Cover client connect,
pub/sub, protocol parsing, max payload validation, slow consumer
detection, TLS, auth timeout, server startup/shutdown, version parsing,
and write deadline enforcement.
42 new tests ported from client_test.go and server_test.go.
Port Go consumer_test.go and jetstream_test.go consumer lifecycle tests.
Cover pause/resume state machine, replay rate config, priority pull
requests, max delivery, ephemeral recovery, durable reconnect, and
consumer file store state persistence.
49 new tests ported from consumer_test.go and jetstream_test.go.
Port Go jetstream_test.go storage/recovery/encryption tests. Add stream
recovery stubs, encryption key management, direct-get with time queries,
and subject delete marker handling.
23 new tests ported from jetstream_test.go.
Port Go store_test.go contract tests for IStreamStore interface using
MemStore. Fix CompactInternal to correctly walk forward to find new
FirstSeq before backward cleanup (matching Go behavior).
21 new tests ported from store_test.go.
Port Go filestore tombstone/deletion tests, consumer state encode/decode,
consumer file store persistence, and message TTL enforcement. Adds
ConsumerStateCodec and ConsumerFileStore implementations.
17 new tests ported from filestore_test.go.
Ports 34 Go FileStore tests from filestore_test.go to
FileStoreRecovery2Tests.cs (31 pass, 4 skipped). Tests cover block
recovery, compaction, PSIM indexing, skip-msg handling, TTL expiry,
corrupt index/state detection, and read-only permission checks.
Updates docs/test_parity.db with mapped/skipped status for all 34 tests.
Extended the BecomeLeader() fix to JetStreamClusterFixture,
ClusterFailoverFixture, and LeaderFailoverParityFixture. All three
fixtures now auto-simulate leader election after stepdown, matching
the MetaControllerFixture fix from the previous commit.
Re-enabled the leader check in JetStreamApiRouter.Route() that was
commented out during B8 agent work. Added BecomeLeader() method to
JetStreamMetaGroup for single-process test fixtures to simulate
winning the post-stepdown election. MetaControllerFixture now
auto-calls BecomeLeader() after a successful meta leader stepdown.
- RaftGroup, StreamAssignment, ConsumerAssignment types matching Go structs
(jetstream_cluster.go:154-266)
- PlacementEngine.SelectPeerGroup: topology-aware peer selection with cluster
affinity, tag filtering, exclude tags, and storage-weighted sorting
(Go ref: selectPeerGroup at line 7212)
- JetStreamMetaGroup: backward-compatible rewrite with full assignment tracking,
consumer proposal workflow, and delete operations
- 41 new tests in ClusterAssignmentAndPlacementTests
- ProposeAddPeerAsync/ProposeRemovePeerAsync: single-change-at-a-time membership
changes through RAFT consensus (Go ref: raft.go:961-1019)
- RaftLog.Compact: removes entries up to given index for log compaction
- CreateSnapshotCheckpointAsync: creates snapshot and compacts log in one operation
- DrainAndReplaySnapshotAsync: drains commit queue, installs snapshot, resets indices
- Pre-vote protocol skipped (Go NATS doesn't implement it either)
- 23 new tests in RaftMembershipAndSnapshotTests
- CommitQueue<T>: channel-based queue for committed entries awaiting state machine application
- RaftPeerState: tracks replication and health state (nextIndex, matchIndex, lastContact)
- RaftNode: CommitIndex/ProcessedIndex tracking, election timer with randomized 150-300ms interval,
peer state integration with heartbeat and replication updates
- 52 new tests across RaftApplyQueueTests, RaftElectionTimerTests, RaftHealthTests
D6: Add ExportSubjects/ImportSubjects allow-lists to LeafHubSpokeMapper alongside
existing DenyExports/DenyImports deny-lists. When an allow-list is non-empty, subjects
must match at least one allow pattern; deny always takes precedence. Updated
LeafNodeOptions, LeafHubSpokeMapper (5-arg constructor), and LeafNodeManager to wire
through the new allow-lists. Added 13 new unit + integration tests covering allow-list
semantics, deny precedence, bidirectional filtering, and wire-level propagation.
D7: Existing NetworkingGoParityTests.cs (50 tests) covers gateway interest mode,
route pool accounting, and leaf node connections. Parity DB already up to date.
E6: Add IsSystemAccount property to Account, mark $SYS account as system,
add IsSystemSubject/IsSubscriptionAllowed/GetSubListForSubject helpers to
route $SYS.> subjects to the system account's SubList and block non-system
accounts from subscribing.
E7: Add ConfigReloader.ReloadAsync and ApplyDiff for structured async reload,
add ConfigReloadResult/ConfigApplyResult types. SIGHUP handler already wired
via PosixSignalRegistration in HandleSignals.
E8: Add PropagateAuthChanges to re-evaluate connected clients after auth
config reload, disconnecting clients whose credentials no longer pass
authentication with -ERR 'Authorization Violation'.
E4: AccountImportExport with DFS cycle detection for service imports,
RemoveServiceImport/RemoveStreamImport, and ValidateImport authorization.
E5: AccountLimits record with MaxStorage/MaxConsumers/MaxAckPending,
TryReserveConsumer/ReleaseConsumer, TrackStorageDelta on Account.
20 new tests, all passing.
- Consumer priority groups and pull timeout/filter mappings
- Route pool accounting and S2 compression mappings
- MQTT session persistence, QoS 2, and retained message mappings
- Total mapped: 924 → 938 of 2,937
Add MqttSessionStore with save/load/delete/list operations, flapper
detection (backoff on rapid reconnects), and TimeProvider-based testing.
Add MqttRetainedStore for per-topic retained messages with MQTT wildcard
matching (+/# filters). Add MqttQos2StateMachine tracking the full
PUBREC/PUBREL/PUBCOMP flow with duplicate rejection and timeout detection.
19 new tests: 9 session persistence, 10 QoS/retained message tests.
D2: Add FNV-1a-based ComputeRoutePoolIdx to RouteManager matching Go's
route.go:533-545, with PoolIndex on RouteConnection and account-aware
ForwardRoutedMessageAsync that routes to the correct pool connection.
D3: Replace DeflateStream with IronSnappy in RouteCompressionCodec, add
RouteCompressionLevel enum, NegotiateCompression, and IsCompressed
detection. 17 new tests (6 pool + 11 compression), all passing.
