# Full Production Parity Design
|
||||
|
||||
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers-extended-cc:executing-plans to implement this plan task-by-task.
|
||||
|
||||
**Goal:** Close all remaining gaps between the Go NATS server and the .NET port — implementation code and test coverage — achieving full production parity.
|
||||
|
||||
**Current state:** 1,081 tests passing, core pub/sub + JetStream basics + MQTT packet parsing + JWT claims ported. Three major implementation gaps remain: RAFT consensus, FileStore block engine, and internal data structures (AVL, subject tree, GSL, time hash wheel).
|
||||
|
||||
**Approach:** 6-wave slice-by-slice TDD, ordered by dependency. Each wave builds on the prior wave's production code and tests. Parallel subagents within each wave for independent subsystems.
|
||||
|
||||

|
||||
|
||||
## Gap Analysis Summary
|
||||
|
||||
### Implementation Gaps
|
||||
|
||||
| Gap | Go Source | .NET Status | Impact |
|
||||
|-----|-----------|-------------|--------|
|
||||
| RAFT consensus | `server/raft.go` (5,800 lines) | Missing entirely | Blocks clustered JetStream |
|
||||
| FileStore block engine | `server/filestore.go` (337KB) | Flat JSONL stub | Blocks persistent JetStream |
|
||||
| Internal data structures | `server/avl/`, `server/stree/`, `server/gsl/`, `server/thw/` | Missing entirely | Blocks FileStore + RAFT |
|
||||
|
||||
### Test Coverage Gap
|
||||
|
||||
- Go server tests: ~2,937 test functions
|
||||
- .NET tests: 1,081 (32.5% coverage)
|
||||
- Gap: ~1,856 tests across all subsystems
|
||||
|
||||

|
||||
|
||||
## Wave 1: Inventory + Scaffolding
|
||||
|
||||
**Purpose:** Establish project structure, create stub files, set up namespaces.
|
||||
|
||||
**Deliverables:**
|
||||
- Namespace scaffolding: `NATS.Server.Internal.Avl`, `NATS.Server.Internal.SubjectTree`, `NATS.Server.Internal.Gsl`, `NATS.Server.Internal.TimeHashWheel`
|
||||
- Stub interfaces for FileStore block engine
|
||||
- Stub interfaces for RAFT node, log, transport
|
||||
- Test project directory structure for all new subsystems
|
||||
|
||||
**Tests:** 0 (scaffolding only)
|
||||
|
||||
---
|
||||
|
||||
## Wave 2: Internal Data Structures
|
||||
|
||||
**Purpose:** Port Go's internal data structures that FileStore and RAFT depend on.
|
||||
|
||||
### AVL Tree (`server/avl/`)
|
||||
- Sparse sequence set backed by AVL-balanced binary tree
|
||||
- Used for JetStream ack tracking (consumer pending sets)
|
||||
- Key operations: `Insert`, `Delete`, `Contains`, `Range`, `Size`
|
||||
- Go reference: `server/avl/seqset.go`
|
||||
- Port as `NATS.Server.Internal.Avl.SequenceSet`
|
||||
- ~15 tests from Go's `TestSequenceSet*`
|
||||
|
||||
### Subject Tree (`server/stree/`)
|
||||
- Trie for per-subject state in streams (sequence tracking, last-by-subject)
|
||||
- Supports wildcard iteration (`*`, `>`)
|
||||
- Go reference: `server/stree/stree.go`
|
||||
- Port as `NATS.Server.Internal.SubjectTree.SubjectTree<T>`
|
||||
- ~15 tests from Go's `TestSubjectTree*`
|
||||
|
||||
### Generic Subject List (`server/gsl/`)
|
||||
- Optimized trie for subscription matching (alternative to SubList for specific paths)
|
||||
- Go reference: `server/gsl/gsl.go`
|
||||
- Port as `NATS.Server.Internal.Gsl.GenericSubjectList<T>`
|
||||
- ~15 tests from Go's `TestGSL*`
|
||||
|
||||
### Time Hash Wheel (`server/thw/`)
|
||||
- Efficient TTL expiration using hash wheel (O(1) insert/cancel, O(bucket) tick)
|
||||
- Used for message expiry in MemStore and FileStore
|
||||
- Go reference: `server/thw/thw.go`
|
||||
- Port as `NATS.Server.Internal.TimeHashWheel.TimeHashWheel<T>`
|
||||
- ~15 tests from Go's `TestTimeHashWheel*`
|
||||
|
||||
**Total tests:** ~60
|
||||
|
||||
---
|
||||
|
||||
## Wave 3: FileStore Block Engine
|
||||
|
||||
**Purpose:** Replace the flat JSONL FileStore stub with Go-compatible block-based storage.
|
||||
|
||||
### Design Decisions
|
||||
- **Behavioral equivalence** — same 64MB block boundaries and semantics, not byte-level Go file compatibility
|
||||
- **Block format:** Each block is a separate file containing sequential messages with headers
|
||||
- **Compression:** S2 (Snappy variant) per-block, using IronSnappy or equivalent .NET library
|
||||
- **Encryption:** AES-GCM per-block (matching Go's encryption support)
|
||||
- **Recovery:** Block-level recovery on startup (scan for valid messages, rebuild index)
|
||||
|
||||
### Components
|
||||
1. **Block Manager** — manages block files, rotation at 64MB, compaction
|
||||
2. **Message Encoding** — per-message header (sequence, timestamp, subject, data length) + payload
|
||||
3. **Index Layer** — in-memory index mapping sequence → block + offset
|
||||
4. **Subject Index** — per-subject first/last sequence tracking using SubjectTree (Wave 2)
|
||||
5. **Purge/Compact** — subject-based purge, sequence-based purge, compaction
|
||||
6. **Recovery** — startup block scanning, index rebuild
|
||||
|
||||
### Go Reference Files
|
||||
- `server/filestore.go` — main implementation
|
||||
- `server/filestore_test.go` — test suite
|
||||
|
||||
**Total tests:** ~80 (store/load, block rotation, compression, encryption, purge, recovery, subject filtering)
|
||||
|
||||
---
|
||||
|
||||
## Wave 4: RAFT Consensus
|
||||
|
||||
**Purpose:** Faithful behavioral port of Go's RAFT implementation for clustered JetStream.
|
||||
|
||||
### Design Decisions
|
||||
- **Faithful Go port** — not a third-party RAFT library; port Go's `raft.go` directly
|
||||
- **Same state machine semantics** — leader election, log replication, snapshots, membership changes
|
||||
- **Transport abstraction** — pluggable transport (in-process for tests, TCP for production)
|
||||
|
||||
### Components
|
||||
1. **RAFT Node** — state machine (Follower → Candidate → Leader), term/vote tracking
|
||||
2. **Log Storage** — append-only log with compaction, backed by FileStore blocks (Wave 3)
|
||||
3. **Election** — randomized timeout, RequestVote RPC, majority quorum
|
||||
4. **Log Replication** — AppendEntries RPC, leader → follower catch-up, conflict resolution
|
||||
5. **Snapshots** — periodic state snapshots, snapshot transfer to lagging followers
|
||||
6. **Membership Changes** — joint consensus for adding/removing nodes
|
||||
7. **Transport** — RPC abstraction with in-process and TCP implementations
|
||||
|
||||
### Go Reference Files
|
||||
- `server/raft.go` — main implementation (5,800 lines)
|
||||
- `server/raft_test.go` — test suite
|
||||
|
||||
**Total tests:** ~70 (election, log replication, snapshots, membership, split-brain, network partition simulation)
|
||||
|
||||
---
|
||||
|
||||
## Wave 5: JetStream Clustering + Concurrency
|
||||
|
||||
**Purpose:** Wire RAFT into JetStream for clustered operation; add NORACE concurrency tests.
|
||||
|
||||
### Components
|
||||
1. **Meta-Controller** — cluster-wide RAFT group for stream/consumer placement
|
||||
- Ports Go's `jetStreamCluster` struct
|
||||
- Routes `$JS.API.*` requests through meta-group leader
|
||||
- Tests from Go's `TestJetStreamClusterCreate`, `TestJetStreamClusterStreamLeaderStepDown`
|
||||
|
||||
2. **Per-Stream RAFT Groups** — each R>1 stream gets its own RAFT group
|
||||
- Leader accepts publishes, proposes entries, followers apply
|
||||
- Tests: create R3 stream, publish, verify all replicas, step down, verify new leader
|
||||
|
||||
3. **Per-Consumer RAFT Groups** — consumer ack state replicated via RAFT
|
||||
- Tests: ack on leader, verify ack floor propagation, consumer failover
|
||||
|
||||
4. **NORACE Concurrency Suite** — Go's `-race`-tagged tests ported to `Task.WhenAll` patterns
|
||||
- Concurrent pub/sub on same stream
|
||||
- Concurrent consumer creates
|
||||
- Concurrent stream purge during publish
|
||||
|
||||
### Go Reference Files
|
||||
- `server/jetstream_cluster.go`, `server/jetstream_cluster_test.go`
|
||||
- `server/norace_test.go`
|
||||
|
||||
**Total tests:** ~100
|
||||
|
||||
---
|
||||
|
||||
## Wave 6: Remaining Subsystem Test Suites
|
||||
|
||||
**Purpose:** Port remaining Go test functions across all subsystems not covered by Waves 2-5.
|
||||
|
||||
### Subsystems
|
||||
|
||||
| Subsystem | Go Tests | Existing .NET | Gap | Files |
|
||||
|-----------|----------|---------------|-----|-------|
|
||||
| Config reload | ~92 | 3 | ~89 | `Configuration/` |
|
||||
| MQTT bridge | ~123 | 50 | ~73 | `Mqtt/` |
|
||||
| Leaf nodes | ~110 | 2 | ~108 | `LeafNodes/` |
|
||||
| Accounts/auth | ~64 | 15 | ~49 | `Accounts/` |
|
||||
| Gateway | ~87 | 2 | ~85 | `Gateways/` |
|
||||
| Routes | ~73 | 2 | ~71 | `Routes/` |
|
||||
| Monitoring | ~45 | 7 | ~38 | `Monitoring/` |
|
||||
| Client protocol | ~120 | 30 | ~90 | root test dir |
|
||||
| JetStream API | ~200 | 20 | ~180 | `JetStream/` |
|
||||
|
||||
### Approach
|
||||
- Each subsystem is an independent parallel subagent task
|
||||
- Tests organized by .NET namespace matching existing conventions
|
||||
- Each test file has header comment mapping to Go source test function names
|
||||
- Self-contained test helpers duplicated per file (no shared TestHelpers)
|
||||
- Gate verification between subsystem batches
|
||||
|
||||
**Total tests:** ~780-850
|
||||

## Dependency Graph
|
||||
|
||||
```
|
||||
Wave 1 (Scaffolding) ──┬──► Wave 2 (Data Structures) ──► Wave 3 (FileStore) ──► Wave 4 (RAFT) ──► Wave 5 (Clustering)
|
||||
│
|
||||
└──► Wave 6 (Subsystem Suites) [parallel, independent of Waves 2-5]
|
||||
```
|
||||
|
||||
Wave 6 subsystems are mutually independent and can execute in parallel. Waves 2-5 are sequential.
|
||||
|
||||
---
|
||||
|
||||
## Estimated Totals
|
||||
|
||||
| Metric | Value |
|
||||
|--------|-------|
|
||||
| New implementation code | ~15,000-20,000 lines |
|
||||
| New test code | ~12,000-15,000 lines |
|
||||
| New tests | ~1,160 |
|
||||
| Final test count | ~2,241 |
|
||||
| Final Go parity | ~75% of Go test functions |
|
||||
|
||||
## Key Conventions
|
||||
|
||||
- xUnit 3 + Shouldly assertions (never `Assert.*`)
|
||||
- NSubstitute for mocking
|
||||
- Go reference comments on each ported test: `// Go: TestFunctionName server/file.go:line`
|
||||
- Self-contained helpers per test file
|
||||
- C# 14 idioms: primary constructors, collection expressions, file-scoped namespaces
|
||||
- TDD: write failing test first, then minimal implementation
|
||||
- Gated commits between waves

# Full Production Parity Implementation Plan
|
||||
|
||||
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers-extended-cc:executing-plans to implement this plan task-by-task.
|
||||
|
||||
**Goal:** Close all remaining implementation and test gaps between the Go NATS server and the .NET port, achieving full production parity.
|
||||
|
||||
**Architecture:** 6-wave slice-by-slice TDD, ordered by dependency. Waves 2-5 are sequential (each depends on prior wave's production code). Wave 6 subsystem suites are parallel and can begin alongside Wave 2.
|
||||
|
||||
**Tech Stack:** .NET 10 / C# 14, xUnit 3, Shouldly, NSubstitute, System.IO.Pipelines
|
||||

|
||||
- Create: `src/NATS.Server/Raft/RaftNode.cs`
|
||||
- Create: `src/NATS.Server/Raft/RaftState.cs`
|
||||
- Create: `tests/NATS.Server.Tests/Internal/Avl/` (directory)
|
||||
- Create: `tests/NATS.Server.Tests/Internal/SubjectTree/` (directory)

|
||||
- Create: `tests/NATS.Server.Tests/Internal/TimeHashWheel/` (directory)
|
||||
- Create: `tests/NATS.Server.Tests/Raft/` (directory)
|
||||
|
||||
**Step 1: Create namespace stub files with minimal type skeletons**
|
||||
|
||||
Each stub file contains the namespace declaration, a public class/interface with a `// TODO: Port from Go` comment, and the Go reference file path.
|
||||
|
||||
**Step 2: Create test directory structure**
|
||||
|
||||
```bash
|
||||
mkdir -p tests/NATS.Server.Tests/Internal/Avl
|
||||
mkdir -p tests/NATS.Server.Tests/Internal/SubjectTree
|
||||
mkdir -p tests/NATS.Server.Tests/Internal/Gsl
|
||||
mkdir -p tests/NATS.Server.Tests/Internal/TimeHashWheel
|
||||
mkdir -p tests/NATS.Server.Tests/Raft
|
||||
```
|
||||
|
||||
**Step 3: Verify build succeeds**
|
||||
|
||||
Run: `dotnet build NatsDotNet.slnx`
|
||||
Expected: Build succeeded, 0 errors
|
||||
|
||||
**Step 4: Commit**
|
||||
|
||||
```bash
|
||||
git add -A && git commit -m "feat: scaffold namespaces for data structures, FileStore, and RAFT"
|
||||
```
|
||||

|
||||
|
||||
## Task 1: AVL Tree / SequenceSet
|
||||
|
||||
**Files:**
|
||||
- Create: `src/NATS.Server/Internal/Avl/SequenceSet.cs`
|
||||
- Create: `tests/NATS.Server.Tests/Internal/Avl/SequenceSetTests.cs`
|
||||
- Test: `tests/NATS.Server.Tests/Internal/Avl/SequenceSetTests.cs`
|
||||
|
||||
**Go reference:** `server/avl/seqset.go` + `server/avl/seqset_test.go` (16 test functions)
|
||||
|
||||
**Public API to port:**
|
||||
|
||||
```csharp
|
||||
namespace NATS.Server.Internal.Avl;
|
||||
|
||||
public class SequenceSet
|
||||
{
|
||||
public void Insert(ulong seq);
|
||||
public bool Exists(ulong seq);
|
||||
public bool Delete(ulong seq);
|
||||
public void SetInitialMin(ulong min);
|
||||
public int Size { get; }
|
||||
public int Nodes { get; }
|
||||
public void Empty();
|
||||
public bool IsEmpty { get; }
|
||||
public void Range(Func<ulong, bool> callback);
|
||||
public (int Left, int Right) Heights();
|
||||
public (ulong Min, ulong Max, ulong Num) State();
|
||||
public (ulong Min, ulong Max) MinMax();
|
||||
public SequenceSet Clone();
|
||||
public void Union(params SequenceSet[] others);
|
||||
public static SequenceSet Union(params SequenceSet[] sets);
|
||||
public int EncodeLength();
|
||||
public byte[] Encode();
|
||||
public static (SequenceSet Set, int BytesRead) Decode(ReadOnlySpan<byte> buf);
|
||||
}
|
||||
```
|
||||
|
||||
**Step 1: Write failing tests**
|
||||
|
||||
Port all 16 Go test functions:
|
||||
- `TestSeqSetBasics` → `Basics_InsertExistsDelete`
|
||||
- `TestSeqSetLeftLean` → `LeftLean_TreeBalancesCorrectly`
|
||||
- `TestSeqSetRightLean` → `RightLean_TreeBalancesCorrectly`
|
||||
- `TestSeqSetCorrectness` → `Correctness_RandomInsertDelete`
|
||||
- `TestSeqSetRange` → `Range_IteratesInOrder`
|
||||
- `TestSeqSetDelete` → `Delete_VariousPatterns`
|
||||
- `TestSeqSetInsertAndDeletePedantic` → `InsertAndDelete_PedanticVerification`
|
||||
- `TestSeqSetMinMax` → `MinMax_TracksCorrectly`
|
||||
- `TestSeqSetClone` → `Clone_IndependentCopy`
|
||||
- `TestSeqSetUnion` → `Union_MergesSets`
|
||||
- `TestSeqSetFirst` → `First_ReturnsMinimum`
|
||||
- `TestSeqSetDistinctUnion` → `DistinctUnion_NoOverlap`
|
||||
- `TestSeqSetDecodeV1` → `DecodeV1_BackwardsCompatible`
|
||||
- `TestNoRaceSeqSetSizeComparison` → `SizeComparison_LargeSet`
|
||||
- `TestNoRaceSeqSetEncodeLarge` → `EncodeLarge_RoundTrips`
|
||||
- `TestNoRaceSeqSetRelativeSpeed` → `RelativeSpeed_Performance`
|
||||
|
||||
**Step 2: Run tests to verify they fail**
|
||||
|
||||
Run: `dotnet test tests/NATS.Server.Tests --filter "FullyQualifiedName~SequenceSetTests" -v quiet`
|
||||
Expected: FAIL (types not implemented)
|
||||
|
||||
**Step 3: Implement SequenceSet**
|
||||
|
||||
Port the AVL tree from `server/avl/seqset.go`. Key implementation details:
|
||||
- Internal `Node` class with `Value`, `Height`, `Left`, `Right`
|
||||
- AVL rotations: `RotateLeft`, `RotateRight`, `Balance`
|
||||
- Run-length encoding for `Encode`/`Decode` (sequences compress into ranges)
|
||||
- The tree stores ranges `[min, max]` in each node, not individual values
|
||||
|
||||
**Step 4: Run tests to verify they pass**
|
||||
|
||||
Run: `dotnet test tests/NATS.Server.Tests --filter "FullyQualifiedName~SequenceSetTests" -v quiet`
|
||||
Expected: PASS (16 tests)
|
||||
|
||||
**Step 5: Commit**
|
||||
|
||||
```bash
|
||||
git add src/NATS.Server/Internal/Avl/ tests/NATS.Server.Tests/Internal/Avl/
|
||||
git commit -m "feat: port AVL SequenceSet from Go with 16 tests"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Task 2: Subject Tree (ART)
|
||||
|
||||
**Files:**
|
||||
- Create: `src/NATS.Server/Internal/SubjectTree/SubjectTree.cs`
|
||||
- Create: `src/NATS.Server/Internal/SubjectTree/Node.cs` (node4, node10, node16, node48, node256, leaf)
|
||||
- Create: `tests/NATS.Server.Tests/Internal/SubjectTree/SubjectTreeTests.cs`
|
||||
|
||||
**Go reference:** `server/stree/stree.go` + 8 node files + `server/stree/stree_test.go` (59 test functions)
|
||||
|
||||
**Public API to port:**
|
||||
|
||||
```csharp
|
||||
namespace NATS.Server.Internal.SubjectTree;
|
||||
|
||||
public class SubjectTree<T>
|
||||
{
|
||||
public int Size { get; }
|
||||
public SubjectTree<T> Empty();
|
||||
public (T? Value, bool Existed) Insert(ReadOnlySpan<byte> subject, T value);
|
||||
public (T? Value, bool Found) Find(ReadOnlySpan<byte> subject);
|
||||
public (T? Value, bool Found) Delete(ReadOnlySpan<byte> subject);
|
||||
public void Match(ReadOnlySpan<byte> filter, Action<byte[], T> callback);
|
||||
public bool MatchUntil(ReadOnlySpan<byte> filter, Func<byte[], T, bool> callback);
|
||||
public bool IterOrdered(Func<byte[], T, bool> callback);
|
||||
public bool IterFast(Func<byte[], T, bool> callback);
|
||||
}
|
||||
```
|
||||
|
||||
**Step 1: Write failing tests**
|
||||
|
||||
Port all 59 Go test functions. Key groupings:
|
||||
- Basic CRUD: `TestSubjectTreeBasics`, `TestSubjectTreeNoPrefix`, `TestSubjectTreeEmpty` → 5 tests
|
||||
- Node growth/shrink: `TestSubjectTreeNodeGrow`, `TestNode256Operations`, `TestNode256Shrink` → 8 tests
|
||||
- Matching: `TestSubjectTreeMatchLeafOnly`, `TestSubjectTreeMatchNodes`, `TestSubjectTreeMatchUntil` + 10 more → 15 tests
|
||||
- Iteration: `TestSubjectTreeIterOrdered`, `TestSubjectTreeIterFast` + edge cases → 8 tests
|
||||
- Delete: `TestSubjectTreeNodeDelete` + edge cases → 6 tests
|
||||
- Intersection: `TestSubjectTreeLazyIntersect`, `TestSubjectTreeGSLIntersection` → 3 tests
|
||||
- Edge cases and bug regression: remaining 14 tests
|
||||
|
||||

||||
|
||||
Run: `dotnet test tests/NATS.Server.Tests --filter "FullyQualifiedName~SubjectTreeTests" -v quiet`
|
||||
Expected: FAIL
|
||||
|
||||
**Step 3: Implement SubjectTree**

||||
- 5 node types: `Node4`, `Node10`, `Node16`, `Node48`, `Node256` (capacity-tiered)
|
||||
- Generic `Leaf<T>` for values
|
||||
- `Parts` helper for subject tokenization (split on `.`)
|
||||
- `MatchParts` for wildcard matching (`*` single, `>` multi)
|
||||
- Node interface: `AddChild`, `FindChild`, `DeleteChild`, `IsFull`, `Grow`, `Shrink`, `Iter`
|
||||
|
||||
**Step 4: Run tests to verify they pass**
|
||||
|
||||
Run: `dotnet test tests/NATS.Server.Tests --filter "FullyQualifiedName~SubjectTreeTests" -v quiet`
|
||||
Expected: PASS (59 tests)
|
||||
|
||||
**Step 5: Commit**
|
||||
|
||||
```bash
|
||||

|
||||
- `*` and `>` wildcard child pointers
|
||||
- Thread-safe via `ReaderWriterLockSlim`
|
||||
