The project is currently developed under https://github.com/ZeruLight/Erupe
|
||||
|
||||
The project is currently developed under <https://github.com/ZeruLight/Erupe>
|
||||
|
||||
## History of development
|
||||
|
||||
Development of this project dates back to 2019, and was developed under various umbrellas over time:
|
||||
* Cappuccino (Fist/Ando/Ellie42) ("The Erupe Developers"), 2019-2020 (https://github.com/Ellie42/Erupe / https://github.com/ricochhet/Erupe-Legacy) (Still active closed source)
|
||||
* Einherjar Team, ????-2022 Feb (There is no git history for this period, this team's work was taken and used as a foundation for future repositories)
|
||||
* Community Edition, 2022 (https://github.com/xl3lackout/Erupe)
|
||||
* sekaiwish Fork, 2022 (https://github.com/sekaiwish/Erupe)
|
||||
* ZeruLight, 2022-2023 (https://github.com/ZeruLight/Erupe)
|
||||
|
||||
### Cappuccino (Fist/Ando/Ellie42) - "The Erupe Developers" (2019-2020)
|
||||
|
||||
<https://github.com/Ellie42/Erupe> / <https://github.com/ricochhet/Erupe-Legacy>
|
||||
|
||||
**Initial proof-of-concept** and foundational work:
|
||||
|
||||
* Basic server infrastructure (Sign, Entrance, Channel servers)
|
||||
* Account registration and character creation systems
|
||||
* Initial multiplayer lobby functionality
|
||||
* Core network communication layer
|
||||
* Save data compression using delta/diff encoding
|
||||
* Stage management and reservation systems for multiplayer quests
|
||||
* Party system supporting up to 4 players
|
||||
* Chat system (local, party, private messaging)
|
||||
* Hunter Navi NPC interactions
|
||||
* Diva Defense feature
|
||||
* Quest selection and basic quest support
|
||||
* PostgreSQL database integration with migration support
|
||||
|
||||
**Technical Details:**
|
||||
|
||||
* Repository created: March 6, 2020
|
||||
* Public commits: March 4-12, 2020 (9 days of visible development)
|
||||
* Total commits: 142
|
||||
* Status: Still active closed source
|
||||
|
||||
The original developers created this as an educational project to learn server emulation. This version established the fundamental architecture that all subsequent versions built upon.
|
||||
|
||||
### Einherjar Team (~2020-2022 Feb)
|
||||
|
||||
**Major expansion period** (estimated March 2020 - February 2022):
|
||||
|
||||
Unfortunately, **no public git history exists** for this critical development period. The Einherjar Team's work was used as the foundation for all subsequent community repositories. Based on features present in the Community Edition fork (February 2022) that weren't in the original Cappuccino version, the Einherjar Team likely implemented:
|
||||
|
||||
* Extensive quest system improvements
|
||||
* Guild system foundations
|
||||
* Economy and item distribution systems
|
||||
* Additional game mechanics and features
|
||||
* Stability improvements and bug fixes
|
||||
* Database schema expansions
|
||||
|
||||
This ~2-year period represents the largest gap in documented history. If anyone has information about this team's contributions, please contact the project maintainers.
|
||||
|
||||
### Community Edition (2022)

# Changelog
|
||||
|
||||
All notable changes to this project will be documented in this file.
|
||||
|
||||
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
|
||||
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
||||
|
||||
## [Unreleased]
|
||||
|
||||
### Added
|
||||
|
||||
- Catch-up migration (`0002_catch_up_patches.sql`) for databases with partially-applied patch schemas — idempotent no-op on fresh or fully-patched databases, fills gaps for partial installations
|
||||
- Embedded auto-migrating database schema system (`server/migrations/`): the server binary now contains all SQL schemas and runs migrations automatically on startup — no more `pg_restore`, manual patch ordering, or external `schemas/` directory needed
|
||||
- Setup wizard: web-based first-run configuration at `http://localhost:8080` when `config.json` is missing — guides users through database connection, schema initialization, and server settings
|
||||
- CI: Coverage threshold enforcement — fails build if total coverage drops below 50%
|
||||
- CI: Release workflow that automatically builds and uploads Linux/Windows binaries to GitHub Releases on tag push
|
||||
- Monthly guild item claim tracking per character per type (standard/HLC/EXC), with schema migration (`31-monthly-items.sql`) adding claim timestamps to the `stamps` table
|
||||
- API: `GET /version` endpoint returning server name and client mode (`{"clientMode":"ZZ","name":"Erupe-CE"}`)
|
||||
- Rework object ID allocation: per-session IDs replace shared map, simplify stage entry notifications
|
||||
- Better config file handling and structure
|
||||
- Comprehensive production logging for save operations (warehouse, Koryo points, savedata, Hunter Navi, plate equipment)
|
||||
- Disconnect type tracking (graceful, connection_lost, error) with detailed logging
|
||||
- Session lifecycle logging with duration and metrics tracking
|
||||
- Structured logging with timing metrics for all database save operations
|
||||
- Plate data (transmog) safety net in logout flow - adds monitoring checkpoint for platedata, platebox, and platemyset persistence
|
||||
- Unit tests for `handlers_data_paper.go`: 20 tests covering all DataType branches, ACK payload structure, serialization round-trips, and paperGiftData table integrity
|
||||
|
||||
### Changed
|
||||
|
||||
- Schema management consolidated: replaced 4 independent code paths (Docker shell script, setup wizard, test helpers, manual psql) with a single embedded migration runner
|
||||
- Setup wizard simplified: 3 schema checkboxes replaced with single "Apply database schema" checkbox
|
||||
- Docker simplified: removed schema volume mounts and init script — the server binary handles everything
|
||||
- Test helpers simplified: `ApplyTestSchema` now uses the migration runner instead of `pg_restore` + manual patch application
|
||||
- Updated minimum Go version requirement from 1.23 to 1.25
|
||||
- Improved config handling
|
||||
- Refactored logout flow to save all data before cleanup (prevents data loss race conditions)
|
||||
- Unified save operation into single `saveAllCharacterData()` function with proper error handling
|
||||
- Removed duplicate save calls in `logoutPlayer()` function
|
||||
|
||||
### Fixed
|
||||
|
||||
- Config file handling and validation
|
||||
- Fixes 3 critical race condition in handlers_stage.go.
|
||||

|
||||
- Fixed crash when sending empty packets in QueueSend/QueueSendNonBlocking
|
||||
- Fixed missing stage transfer packet for empty zones
|
||||
- Fixed save data corruption check rejecting valid saves due to name encoding mismatches (SJIS/UTF-8)
|
||||
- Fixed incomplete saves during logout - character savedata now persisted even during ungraceful disconnects
|
||||
- Fixed double-save bug in logout flow that caused unnecessary database operations
|
||||
- Fixed save operation ordering - now saves data before session cleanup instead of after
|
||||
- Fixed stale transmog/armor appearance shown to other players - user binary cache now invalidated when plate data is saved
|
||||
- Fixed client crash when quest or scenario files are missing - now sends failure ack instead of nil data
|
||||
- Fixed server crash when Discord relay receives messages with unsupported Shift-JIS characters (emoji, Lenny faces, cuneiform, etc.)
|
||||
- Fixed data race in token.RNG global used concurrently across goroutines
|
||||
|
||||

## Historical Context
|
||||
|
||||
This changelog documents all known changes from the Community Edition reupload (February 25, 2022) onwards. The period before this (Einherjar Team era, ~2020-2022) has no public git history.
|
||||
|
||||
Earlier development by Cappuccino/Ellie42 (March 2020) focused on basic server infrastructure, multiplayer systems, and core functionality. See [AUTHORS.md](AUTHORS.md) for detailed development history.
|
||||
|
||||
The project began following semantic versioning with v9.0.0 (August 3, 2022) and maintains tagged releases for stable versions. Development continues on the main branch with features merged from feature branches.

# CLAUDE.md
|
||||
|
||||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||
|
||||
## Project Overview
|
||||
|
||||
Erupe is a Go server emulator for Monster Hunter Frontier, a shut-down MMORPG. It handles authentication, world selection, and gameplay in a single binary running four TCP/HTTP servers. Go 1.25+ required.
|
||||
|
||||
## Build & Test Commands
|
||||
|
||||
```bash
|
||||
go build -o erupe-ce # Build server
|
||||
go build -o protbot ./cmd/protbot/ # Build protocol bot
|
||||
go test -race ./... -timeout=10m # Run tests (race detection mandatory)
|
||||
go test -v ./server/channelserver/... # Test one package
|
||||
go test -run TestHandleMsg ./server/channelserver/... # Single test
|
||||
go test -coverprofile=coverage.out ./... && go tool cover -func=coverage.out # Coverage (CI requires ≥50%)
|
||||
gofmt -w . # Format
|
||||
golangci-lint run ./... # Lint (v2 standard preset, must pass CI)
|
||||
```
|
||||
|
||||
Docker (from `docker/`):
|
||||
```bash
|
||||
docker compose up db pgadmin # PostgreSQL + pgAdmin (port 5050)
|
||||
docker compose up server # Erupe (after DB is healthy)
|
||||
```
|
||||
|
||||
## Architecture
|
||||
|
||||
### Four-Server Model (single binary, orchestrated from `main.go`)
|
||||
|
||||
```
|
||||
Client ←[Blowfish TCP]→ Sign Server (53312) → Authentication, sessions
|
||||
→ Entrance Server (53310) → Server list, character select
|
||||
→ Channel Servers (54001+) → Gameplay, quests, multiplayer
|
||||
→ API Server (8080) → REST API (/health, /version, V2 sign)
|
||||
```
|
||||
|
||||
Each server is in its own package under `server/`. The channel server is by far the largest (~200 files).
|
||||
|
||||
### Channel Server Packet Flow
|
||||
|
||||
1. `network/crypt_conn.go` decrypts TCP stream (Blowfish)
|
||||
2. `network/mhfpacket/` deserializes binary packet into typed struct (~453 packet types, one file each)
|
||||
3. `handlers_table.go` dispatches via `buildHandlerTable()` (~200+ `PacketID → handlerFunc` entries)
|
||||
4. Handler in appropriate `handlers_*.go` processes it (organized by game system)
|
||||
|
||||
Handler signature: `func(s *Session, p mhfpacket.MHFPacket)`
|
||||
|
||||
### Layered Architecture
|
||||
|
||||
```
|
||||
handlers_*.go → svc_*.go (service layer) → repo_*.go (data access)
|
||||
(where needed) ↓
|
||||
repo_interfaces.go (21 interfaces)
|
||||
↓
|
||||
repo_mocks_test.go (test doubles)
|
||||
```
|
||||
|
||||
- **Handlers**: Parse packets, call services or repos, build responses. Must always send ACK (see Error Handling below). Simple CRUD operations call repos directly; multi-step or cross-repo logic goes through services.
|
||||
- **Services**: Encapsulate business logic that spans multiple repos or requires orchestration beyond simple CRUD. Not a mandatory pass-through — handlers call repos directly for straightforward data access.
|
||||
- **Repositories**: All SQL lives in `repo_*.go` files behind interfaces in `repo_interfaces.go`. The `Server` struct holds interface types, not concrete implementations. Handler code must never contain inline SQL.
|
||||
- **Sign server** has its own repo pattern: 3 interfaces in `server/signserver/repo_interfaces.go`.
|
||||
|
||||
#### Services
|
||||
|
||||
| Service | File | Methods | Purpose |
|
||||
|---------|------|---------|---------|
|
||||
| `GuildService` | `svc_guild.go` | 6 | Member operations, disband, resign, leave, scout — triggers cross-repo mail |
|
||||
| `MailService` | `svc_mail.go` | 4 | Send/broadcast mail with message type routing |
|
||||
| `GachaService` | `svc_gacha.go` | 6 | Gacha rolls (normal/stepup/box), point transactions, reward resolution |
|
||||
| `AchievementService` | `svc_achievement.go` | 2 | Achievement fetch with score computation, increment |
|
||||
| `TowerService` | `svc_tower.go` | 3 | Tower gem management, tenrourai progress capping, guild RP donation |
|
||||
| `FestaService` | `svc_festa.go` | 2 | Event lifecycle (expiry/cleanup/creation), soul submission filtering |
|
||||
|
||||
Each service takes repo interfaces + `*zap.Logger` in its constructor, making it testable with mocks. Tests live in `svc_*_test.go` files alongside the service.
|
||||
|
||||
### Key Subsystems
|
||||
|
||||
| File(s) | Purpose |
|
||||
|---------|---------|
|
||||
| `sys_session.go` | Per-connection state: character, stage, semaphores, send queue |
|
||||
| `sys_stage.go` | `StageMap` (`sync.Map`-backed), multiplayer rooms/lobbies |
|
||||
| `sys_channel_server.go` | Server lifecycle, Raviente shared state, world management |
|
||||
| `sys_semaphore.go` | Distributed locks for events (Raviente siege, guild ops) |
|
||||
| `channel_registry.go` | Cross-channel operations (worldcast, session lookup, mail) |
|
||||
| `handlers_cast_binary.go` | Binary state relay between clients (position, animation) |
|
||||
| `handlers_helpers.go` | `loadCharacterData`/`saveCharacterData` shared helpers |
|
||||
| `guild_model.go` | Guild data structures |
|
||||
|
||||
### Binary Serialization
|
||||
|
||||
`common/byteframe.ByteFrame` — sequential big-endian reads/writes with sticky error pattern (`bf.Err()`). Used for all packet parsing, response building, and save data manipulation. Use `encoding/binary` only for random-access reads at computed offsets on existing `[]byte` slices.
|
||||
|
||||
### Database
|
||||
|
||||
PostgreSQL with embedded auto-migrating schema in `server/migrations/`:
|
||||
- `sql/0001_init.sql` — consolidated baseline
|
||||
- `seed/*.sql` — demo data (applied via `migrations.ApplySeedData()` on fresh DB)
|
||||
- New migrations: `sql/0002_description.sql`, etc. (each runs in its own transaction)
|
||||
|
||||
The server runs `migrations.Migrate()` automatically on startup.
|
||||
|
||||
### Configuration
|
||||
|
||||
Two reference files: `config.example.json` (minimal) and `config.reference.json` (all options). Loaded via Viper in `config/config.go`. All defaults registered in code. Supports 40 client versions (S1.0 → ZZ) via `ClientMode`. If `config.json` is missing, an interactive setup wizard launches at `http://localhost:8080`.
|
||||
|
||||
### Protocol Bot (`cmd/protbot/`)
|
||||
|
||||
Headless MHF client implementing the complete sign → entrance → channel flow. Shares `common/` and `network/crypto` but avoids `config` dependency via its own `conn/` package.
|
||||
|
||||
## Concurrency
|
||||
|
||||
Lock ordering: `Server.Mutex → Stage.RWMutex → semaphoreLock`. Stage map uses `sync.Map`; individual `Stage` structs have `sync.RWMutex`. Cross-channel operations go exclusively through `ChannelRegistry` — never access other servers' state directly.
|
||||
|
||||
## Error Handling in Handlers
|
||||
|
||||
The MHF client expects `MsgSysAck` for most requests. Missing ACKs cause client softlocks. On error paths, always send `doAckBufFail`/`doAckSimpleFail` before returning.
|
||||
|
||||
## Testing
|
||||
|
||||
- **Mock repos**: Handler tests use `repo_mocks_test.go` — no database needed
|
||||
- **Table-driven tests**: Standard pattern (see `handlers_achievement_test.go`)
|
||||
- **Race detection**: `go test -race` is mandatory in CI
|
||||
- **Coverage floor**: CI enforces ≥50% total coverage
|
||||
|
||||
## Adding a New Packet
|
||||
|
||||
1. Define struct in `network/mhfpacket/msg_*.go` (implements `MHFPacket` interface: `Parse`, `Build`, `Opcode`)
|
||||
2. Add packet ID constant in `network/packetid.go`
|
||||
3. Register handler in `server/channelserver/handlers_table.go`
|
||||
4. Implement handler in appropriate `handlers_*.go` file
|
||||
|
||||
## Adding a Database Query
|
||||
|
||||
1. Add method signature to the relevant interface in `repo_interfaces.go`
|
||||
2. Implement in the corresponding `repo_*.go` file
|
||||
3. Add mock implementation in `repo_mocks_test.go`
|
||||
|
||||
## Adding Business Logic
|
||||
|
||||
If the new logic involves multi-step orchestration, cross-repo coordination, or non-trivial data transformation:
|
||||
|
||||
1. Add or extend a service in the appropriate `svc_*.go` file
|
||||
2. Wire it in `sys_channel_server.go` (constructor + field on `Server` struct)
|
||||
3. Add tests in `svc_*_test.go` using mock repos
|
||||
4. Call the service from the handler instead of the repo directly
|
||||
|
||||
Simple CRUD operations should stay as direct repo calls from handlers — not everything needs a service.
|
||||
|
||||
## Known Issues
|
||||
|
||||
See `docs/anti-patterns.md` for structural patterns and `docs/technical-debt.md` for specific fixable items with file paths and line numbers.

|
||||
```
|
||||
|
||||
## Code Contribution Workflow
|
||||
|
||||
1. **Create a branch** for your changes:
|
||||
|
||||
```bash
|
||||
git checkout -b feature/your-feature-name
|
||||
```
|
||||
|

|
||||
|
||||
2. **Make your changes** and commit them with clear, descriptive messages:
|
||||
|
||||
```bash
|
||||
git commit -m "feat: add new quest loading system"
|
||||
git commit -m "fix: resolve database connection timeout"
|
||||
git commit -m "docs: update configuration examples"
|
||||
```
|
||||
|
||||
3. **Test your changes** (see [Testing Requirements](#testing-requirements))
|
||||
|
||||
4. **Push to your fork**:
|
||||
|
||||
```bash
|
||||
git push origin feature/your-feature-name
|
||||
```
|
||||
|
||||
5. **Create a Pull Request** on GitHub with:
|
||||
- Clear description of what changes you made
|
||||
- Why the changes are needed
|
||||
- Any related issue numbers
|
||||
|
||||
6. **Respond to code review feedback** promptly
|
||||
|
||||
## Coding Standards
|
||||
|
||||
### Go Style
|
||||
|
||||
- Run `gofmt` before committing:
|
||||
|
||||
```bash
|
||||
gofmt -w .
|
||||
```
|
||||
|
||||
- Use `golangci-lint` for linting:
|
||||
|
||||
```bash
|
||||
golangci-lint run ./...
|
||||
```
|
||||
|
||||
- Follow standard Go naming conventions
|
||||
- Keep functions focused and reasonably sized
|
||||
- Add comments for exported functions and complex logic
|
||||
- Handle errors explicitly (don't ignore them)
|
||||
|
||||
### Code Organization
|
||||
|
||||
- Place new handlers in appropriate files under `server/channelserver/`
|
||||
- Keep database queries in structured locations
|
||||
- Use the existing pattern for message handlers
|
||||
|
||||
## Testing Requirements
|
||||
|
||||
Before submitting a pull request:
|
||||
|
||||
1. **Run all tests**:
|
||||
|
||||
```bash
|
||||
go test -v ./...
|
||||
```
|
||||
|
||||
2. **Check for race conditions**:
|
||||
|
||||
```bash
|
||||
go test -v -race ./...
|
||||
```
|
||||
|
||||
3. **Ensure your code has adequate test coverage**:
|
||||
|
||||
```bash
|
||||
go test -v -cover ./...
|
||||
```
|
||||
|
||||
### Writing Tests
|
||||
|
||||
- Add tests for new features in `*_test.go` files
|
||||
- Test edge cases and error conditions
|
||||
- Use table-driven tests for multiple scenarios
|
||||
- Mock external dependencies where appropriate
|
||||
|
||||
Example:
|
||||
|
||||
```go
|
||||
func TestYourFunction(t *testing.T) {
|
||||
tests := []struct {
|
||||
name string
|
||||
input int
|
||||
want int
|
||||
}{
|
||||
{"basic case", 1, 2},
|
||||
{"edge case", 0, 0},
|
||||
}
|
||||
for _, tt := range tests {
|
||||
t.Run(tt.name, func(t *testing.T) {
|
||||
got := YourFunction(tt.input)
|
||||
if got != tt.want {
|
||||
t.Errorf("got %v, want %v", got, tt.want)
|
||||
}
|
||||
})
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Database Schema Changes
|
||||
|
||||
Erupe uses an embedded auto-migrating schema system in `server/migrations/`.
|
||||
|
||||
When adding schema changes:
|
||||
|
||||
1. Create a new file in `server/migrations/sql/` with format: `NNNN_description.sql` (e.g. `0002_add_new_table.sql`)
|
||||
2. Increment the number from the last migration
|
||||
3. Test the migration on both a fresh and existing database
|
||||
4. Document what the migration does in SQL comments
|
||||
|
||||
Migrations run automatically on startup in order. Each runs in its own transaction and is tracked in the `schema_version` table.
|
||||
|
||||
For seed/demo data (shops, events, gacha), add files to `server/migrations/seed/`. Seed data is applied automatically on fresh databases and can be re-applied via the setup wizard.
|
||||
|
||||
## Documentation Requirements
|
||||
|
||||
### Always Update
|
||||
|
||||
- **[CHANGELOG.md](CHANGELOG.md)**: Document your changes under "Unreleased" section
|
||||
- Use categories: Added, Changed, Fixed, Removed, Security
|
||||
- Be specific about what changed and why
|
||||
|
||||
### When Applicable
|
||||
|
||||
- **[README.md](README.md)**: Update if you change:
|
||||
- Installation steps
|
||||
- Configuration options
|
||||
- Requirements
|
||||
- Usage instructions
|
||||
|
||||
- **Code Comments**: Add or update comments for:
|
||||
- Exported functions and types
|
||||
- Complex algorithms
|
||||
- Non-obvious business logic
|
||||
- Packet structures and handling
|
||||

|
||||
|
||||
Erupe is a community-maintained server emulator for Monster Hunter Frontier written in Go. It is a complete reverse-engineered solution to self-host a Monster Hunter Frontier server, using no code from Capcom.
|
||||
|
||||
## Quick Start
|
||||
|
||||
Pick one of three installation methods, then continue to [Quest & Scenario Files](#quest--scenario-files).
|
||||
|
||||
### Option A: Docker (recommended)
|
||||
|
||||
Docker handles the database automatically. You only need to provide quest files and a config.
|
||||
|
||||
1. Clone the repository and enter the Docker directory:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/Mezeporta/Erupe.git
|
||||
cd Erupe
|
||||
```
|
||||
|
||||
2. Copy and edit the config (set your database password to match `docker-compose.yml`):
|
||||
|
||||
```bash
|
||||
cp config.example.json docker/config.json
|
||||
# Edit docker/config.json — set Database.Host to "db"
|
||||
```
|
||||
|
||||
3. Download [quest/scenario files](#quest--scenario-files) and extract them to `docker/bin/`
|
||||
|
||||
4. Start everything:
|
||||
|
||||
```bash
|
||||
cd docker
|
||||
docker compose up
|
||||
```
|
||||
|
||||
pgAdmin is available at `http://localhost:5050` for database management.
|
||||
|
||||
See [docker/README.md](./docker/README.md) for more details (local builds, troubleshooting).
|
||||
|
||||
### Option B: Pre-compiled Binary
|
||||
|
||||
1. Download the latest release for your platform from [GitHub Releases](https://github.com/Mezeporta/Erupe/releases/latest):
|
||||
- `erupe-ce` for Linux
|
||||
- `erupe.exe` for Windows
|
||||
|
||||
2. Set up PostgreSQL and create a database:
|
||||
|
||||
```bash
|
||||
createdb -U postgres erupe
|
||||
```
|
||||
|
||||
The server will automatically apply all schema migrations on first startup.
|
||||
|
||||
3. Copy and edit the config:
|
||||
|
||||
```bash
|
||||
cp config.example.json config.json
|
||||
# Edit config.json with your database credentials
|
||||
```
|
||||
|
||||
4. Download [quest/scenario files](#quest--scenario-files) and extract them to `bin/`
|
||||
|
||||
5. Run: `./erupe-ce`
|
||||
|
||||
### Option C: From Source
|
||||
|
||||
Requires [Go 1.25+](https://go.dev/dl/) and [PostgreSQL](https://www.postgresql.org/download/).
|
||||
|
||||
1. Clone and build:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/Mezeporta/Erupe.git
|
||||
cd Erupe
|
||||
go mod download
|
||||
go build -o erupe-ce
|
||||
```
|
||||
|
||||
2. Set up the database (same as Option B, steps 2–3)
|
||||
|
||||
3. Copy and edit the config:
|
||||
|
||||
```bash
|
||||
cp config.example.json config.json
|
||||
```
|
||||
|
||||
4. Download [quest/scenario files](#quest--scenario-files) and extract them to `bin/`
|
||||
|
||||
5. Run: `./erupe-ce`
|
||||
|
||||
## Quest & Scenario Files
|
||||
|
||||
**Download**: [Quest and Scenario Binary Files](https://files.catbox.moe/xf0l7w.7z)
|
||||
|
||||
These files contain quest definitions and scenario data that the server sends to clients during gameplay. Extract the archive into your `bin/` directory (or `docker/bin/` for Docker installs). The path must match the `BinPath` setting in your config (default: `"bin"`).
|
||||
|
||||
**Without these files, quests will not load and the client will crash.**
|
||||
|
||||
## Client Setup
|
||||
|
||||
1. Obtain a Monster Hunter Frontier client (version G10 or later recommended)
|
||||
2. Point the client to your server by editing `host.txt` or using a launcher to redirect to your server's IP
|
||||
3. Launch `mhf.exe`, select your server, and create an account
|
||||
|
||||
If you have an **installed** copy of Monster Hunter Frontier on an old hard drive, **please** get in contact so we can archive it!
|
||||
|
||||
## Updating
|
||||
|
||||
### From Source
|
||||
|
||||
```bash
|
||||
git pull origin main
|
||||
go mod tidy
|
||||
go build -o erupe-ce
|
||||
```
|
||||
|
||||
Database schema migrations are applied automatically when the server starts — no manual SQL steps needed.
|
||||
|
||||
### Docker
|
||||
|
||||
```bash
|
||||
cd docker
|
||||
docker compose down
|
||||
docker compose build
|
||||
docker compose up
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
Edit `config.json` before starting the server. The essential settings are:
|
||||
|
||||
```json
|
||||
{
|
||||
"Host": "127.0.0.1",
|
||||
"BinPath": "bin",
|
||||
"Language": "en",
|
||||
"ClientMode": "ZZ",
|
||||
"Database": {
|
||||
"Host": "localhost",
|
||||
"Port": 5432,
|
||||
"User": "postgres",
|
||||
"Password": "your_password",
|
||||
"Database": "erupe"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
| Setting | Description |
|
||||
|---------|-------------|
|
||||
| `Host` | IP advertised to clients. Use `127.0.0.1` for local play, your LAN/WAN IP for remote. Leave blank in config to auto-detect |
|
||||
| `ClientMode` | Target client version (`ZZ`, `G10`, `Forward4`, etc.) |
|
||||
| `BinPath` | Path to quest/scenario files |
|
||||
| `Language` | `"en"` or `"jp"` |
|
||||
|
||||
`config.example.json` is intentionally minimal — all other settings have sane defaults built into the server. For the full configuration reference (gameplay multipliers, debug options, Discord integration, in-game commands, entrance/channel definitions), see [config.reference.json](./config.reference.json) and the [Erupe Wiki](https://github.com/Mezeporta/Erupe/wiki).
|
||||
|
||||
## Features
|
||||
|
||||
- **Multi-version Support**: Compatible with all Monster Hunter Frontier versions from Season 6.0 to ZZ
|
||||
- **Multi-platform**: Supports PC, PlayStation 3, PlayStation Vita, and Wii U (up to Z2)
|
||||
- **Complete Server Emulation**: Entry/Sign server, Channel server, and Launcher server
|
||||
- **Gameplay Customization**: Configurable multipliers for experience, currency, and materials
|
||||
- **Event Systems**: Support for Raviente, MezFes, Diva, Festa, and Tournament events
|
||||
- **Discord Integration**: Optional real-time Discord bot integration
|
||||

||||
- **Developer Tools**: Comprehensive logging, packet debugging, and save data dumps
|
||||
|
||||
## Architecture
|
||||
|
||||
Erupe consists of three main server components:
|
||||
|
||||
- **Sign Server** (Port 53312): Handles authentication and account management
|
||||
- **Entrance Server** (Port 53310): Manages world/server selection
|
||||
- **Channel Servers** (Ports 54001+): Handle game sessions, quests, and player interactions
|
||||
|
||||
Multiple channel servers can run simultaneously, organized by world types: Newbie, Normal, Cities, Tavern, Return, and MezFes.
|
||||
|
||||
## Client Compatibility
|
||||
|
||||
### Platforms
|
||||
|
||||
- PC
|
||||
- PlayStation 3
|
||||
- PlayStation Vita
|
||||
- Wii U (Up to Z2)
|
||||
### Versions (ClientMode)
|
||||
- All versions after HR compression (G10-ZZ) have been tested extensively and have great functionality.
|
||||
- All versions available on Wii U (G3-Z2) have been tested and should have good functionality.
|
||||
- The second oldest found version is Forward.4 (FW.4), this version has basic functionality.
|
||||
- The oldest found version is Season 6.0 (S6.0), however functionality is very limited.
|
||||
|
||||
If you have an **installed** copy of Monster Hunter Frontier on an old hard drive, **please** get in contact so we can archive it!
|
||||
### Versions
|
||||
|
||||
## Setup
|
||||
- **G10-ZZ** (ClientMode): Extensively tested with great functionality
|
||||
- **G3-Z2** (Wii U): Tested with good functionality
|
||||
- **Forward.4**: Basic functionality
|
||||
- **Season 6.0**: Limited functionality (oldest supported version)
|
||||
|
||||
If you are only looking to install Erupe, please use [a pre-compiled binary](https://github.com/ZeruLight/Erupe/releases/latest).
|
||||
## Database Schemas
|
||||
|
||||
If you want to modify or compile Erupe yourself, please read on.
|
||||
Erupe uses an embedded auto-migrating schema system. Migrations in [server/migrations/sql/](./server/migrations/sql/) are applied automatically on startup — no manual SQL steps needed.
|
||||
|
||||
## Requirements
|
||||
- **Migrations**: Numbered SQL files (`0001_init.sql`, `0002_*.sql`, ...) tracked in a `schema_version` table
|
||||
- **Seed Data**: Demo templates for shops, distributions, events, and gacha in [server/migrations/seed/](./server/migrations/seed/) — applied automatically on fresh databases
|
||||
|
||||
- [Go](https://go.dev/dl/)
|
||||
- [PostgreSQL](https://www.postgresql.org/download/)
|
||||
## Development
|
||||
|
||||
## Installation
|
||||
### Branch Strategy
|
||||
|
||||
1. Bring up a fresh database by using the [backup file attached with the latest release](https://github.com/ZeruLight/Erupe/releases/latest/download/SCHEMA.sql).
|
||||
2. Run each script under [patch-schema](./schemas/patch-schema) as they introduce newer schema.
|
||||
3. Edit [config.json](./config.json) such that the database password matches your PostgreSQL setup.
|
||||
4. Run `go build` or `go run .` to compile Erupe.
|
||||
- **main**: Active development branch with the latest features and improvements
|
||||
- **stable/v9.2.x**: Stable release branch for those seeking stability over cutting-edge features
|
||||
|
||||
## Docker
|
||||
### Running Tests
|
||||
|
||||
Please see [docker/README.md](./docker/README.md). This is intended for quick installs and development, not for production.
|
||||
```bash
|
||||
go test -v ./... # Run all tests
|
||||
go test -v -race ./... # Check for race conditions (mandatory before merging)
|
||||
```
|
||||
|
||||
## Schemas
|
||||
## Troubleshooting
|
||||
|
||||
We source control the following schemas:
|
||||
- Initialization Schema: This initializes the application database to a specific version (9.1.0).
|
||||
- Update Schemas: These are update files that should be ran on top of the initialization schema.
|
||||
- Patch Schemas: These are for development and should be run after running all initialization and update schema. These get condensed into `Update Schemas` and deleted when updated to a new release.
|
||||
- Bundled Schemas: These are demo reference files to give servers standard set-ups.
|
||||
### Server won't start
|
||||
|
||||
Note: Patch schemas are subject to change! You should only be using them if you are following along with development.
|
||||
- Verify PostgreSQL is running: `systemctl status postgresql` (Linux) or `pg_ctl status` (Windows)
|
||||
- Check database credentials in `config.json`
|
||||
- Ensure all required ports are available and not blocked by firewall
|
||||
|
||||
### Client can't connect
|
||||
|
||||
- Verify server is listening: `netstat -an | grep 53310`
|
||||
- Check firewall rules allow traffic on ports 53310, 53312, and 54001+
|
||||
- Ensure client's `host.txt` points to correct server IP
|
||||
- For remote connections, set `"Host"` in config.json to `0.0.0.0` or your server's IP
|
||||
|
||||
### Database schema errors
|
||||
|
||||
- Schema migrations run automatically on startup — check the server logs for migration errors
|
||||
- Check PostgreSQL logs for detailed error messages
|
||||
- Verify database user has sufficient privileges
|
||||
|
||||
### Quest files not loading
|
||||
|
||||
- Confirm `BinPath` in config.json points to extracted quest/scenario files
|
||||
- Verify binary files match your `ClientMode` setting
|
||||
- Check file permissions
|
||||
|
||||
### Debug Logging
|
||||
|
||||
Enable detailed logging in `config.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"DebugOptions": {
|
||||
"LogInboundMessages": true,
|
||||
"LogOutboundMessages": true
|
||||
}
|
||||
}
|
||||
```

# Docker for Erupe
|
||||
|
||||
## Quick Start
|
||||
|
||||
1. From the repository root, copy and edit the config:
|
||||
|
||||
```bash
|
||||
cp config.example.json docker/config.json
|
||||
```
|
||||
|
||||
Edit `docker/config.json` — set `Database.Host` to `"db"` and `Database.Password` to match `docker-compose.yml` (default: `password`). The example config is minimal; see `config.reference.json` for all available options.
|
||||
|
||||
2. Place your [quest/scenario files](https://files.catbox.moe/xf0l7w.7z) in `docker/bin/`.
|
||||
|
||||
3. Start everything:
|
||||
|
||||
```bash
|
||||
cd docker
|
||||
docker compose up
|
||||
```
|
||||
|
||||
The database schema is automatically applied on first start via the embedded migration system.
|
||||
|
||||
pgAdmin is available at `http://localhost:5050` (default login: `user@pgadmin.com` / `password`).
|
||||
|
||||
## Building Locally
|
||||
|
||||
By default the server service pulls the prebuilt image from GHCR. To build from source instead, edit `docker-compose.yml`: comment out the `image` line and uncomment the `build` section, then:
|
||||
|
||||
## Building the container
|
||||
Run the following from the route of the source folder. In this example we give it the tag of dev to seperate it from any other container verions.
|
||||
```bash
|
||||
docker build . -t erupe:dev
|
||||
docker compose up --build
|
||||
```
|
||||
## Running the container in isolation
|
||||
This is just running the container. You can do volume mounts into the container for the `config.json` to tell it to communicate to a database. You will need to do this also for other folders such as `bin` and `savedata`
|
||||
|
||||
## Stopping the Server
|
||||
|
||||
```bash
|
||||
docker run erupe:dev
|
||||
docker compose stop # Stop containers (preserves data)
|
||||
docker compose down # Stop and remove containers (preserves data volumes)
|
||||
```
|
||||
|
||||
## Docker compose
|
||||
Docker compose allows you to run multiple containers at once. The docker compose in this folder has 3 things set up.
|
||||
- postgres
|
||||
- pg admin (Admin interface to make db changes)
|
||||
- erupe
|
||||
To delete all persistent data, remove these directories after stopping:
|
||||
|
||||
We automatically populate the database to the latest version on start. If you you are updating you will need to apply the new schemas manually.
|
||||
- `docker/db-data/`
|
||||
- `docker/savedata/`
|
||||
|
||||
Before we get started you should make sure the database info matches whats in the docker compose file for the environment variables `POSTGRES_PASSWORD`,`POSTGRES_USER` and `POSTGRES_DB`. You can set the host to be the service name `db`.
|
||||
## Updating
|
||||
|
||||
Here is a example of what you would put in the config.json if you was to leave the defaults. It is strongly recommended to change the password.
|
||||
```txt
|
||||
"Database": {
|
||||
"Host": "db",
|
||||
"Port": 5432,
|
||||
"User": "postgres",
|
||||
"Password": "password",
|
||||
"Database": "erupe"
|
||||
},
|
||||
```
|
||||
After pulling new changes, rebuild and restart. Schema migrations are applied automatically on startup.
|
||||
|
||||
Place this file within ./docker/config.json
|
||||
|
||||
You will need to do the same for your bins place these in ./docker/bin
|
||||
|
||||
# Setting up the web hosted materials
|
||||
Clone the Severs repo into ./docker/Severs
|
||||
|
||||
Make sure your hosts are pointing to where this is hosted
|
||||
|
||||
|
||||
|
||||
## Turning off the server safely
|
||||
```bash
|
||||
docker-compose stop
|
||||
docker compose down
|
||||
docker compose build
|
||||
docker compose up
|
||||
```
|
||||
|
||||
## Turning off the server destructive
|
||||
```bash
|
||||
docker-compose down
|
||||
```
|
||||
Make sure if you want to delete your data you delete the folders that persisted
|
||||
- ./docker/savedata
|
||||
- ./docker/db-data
|
||||
## Turning on the server again
|
||||
This boots the db pgadmin and the server in a detached state
|
||||
```bash
|
||||
docker-compose up -d
|
||||
```
|
||||
if you want all the logs and you want it to be in an attached state
|
||||
```bash
|
||||
docker-compose up
|
||||
```
|
||||
## Troubleshooting
|
||||
|
||||
|
||||
# Troubleshooting
|
||||
Q: My Postgres will not populate. A: You're setup.sh is maybe saved as CRLF it needs to be saved as LF.
|
||||
**Postgres won't start on Windows**: Ensure `docker/db-data/` doesn't contain stale data from a different PostgreSQL version. Delete it and restart to reinitialize.

## 1. God Files — Massive Handler Files
|
||||
|
||||
The channel server has large handler files, each mixing DB queries, business logic, binary serialization, and response writing with no layering. Actual line counts (non-test files):
|
||||
|
||||
| File | Lines | Purpose |
|
||||
|------|-------|---------|
|
||||
| `server/channelserver/handlers_session.go` | 794 | Session setup/teardown |
|
||||
| `server/channelserver/handlers_data_paper_tables.go` | 765 | Paper table data |
|
||||
| `server/channelserver/handlers_quest.go` | 722 | Quest lifecycle |
|
||||
| `server/channelserver/handlers_house.go` | 638 | Housing system |
|
||||
| `server/channelserver/handlers_festa.go` | 637 | Festival events |
|
||||
| `server/channelserver/handlers_data_paper.go` | 621 | Paper/data system |
|
||||
| `server/channelserver/handlers_tower.go` | 529 | Tower gameplay |
|
||||
| `server/channelserver/handlers_mercenary.go` | 495 | Mercenary system |
|
||||
| `server/channelserver/handlers_stage.go` | 492 | Stage/lobby management |
|
||||
| `server/channelserver/handlers_guild_info.go` | 473 | Guild info queries |
|
||||
|
||||
These sizes (~500-800 lines) are not extreme by Go standards, but the files mix all architectural concerns. The bigger problem is the lack of layering within each file (see [#3](#3-no-architectural-layering--handlers-do-everything)), not the file sizes themselves.
|
||||
|
||||
**Impact:** Each handler function is a monolith mixing data access, business logic, and protocol serialization. Testing or reusing any single concern is impossible.
|
||||
|
||||
---
|
||||
|
||||
## 2. Missing ACK Responses on Error Paths (Client Softlocks)
|
||||
|
||||
Some handler error paths log the error and return without sending any ACK response to the client. The MHF client uses `MsgSysAck` with an `ErrorCode` field (0 = success, 1 = failure) to complete request/response cycles. When no ACK is sent at all, the client softlocks waiting for a response that never arrives.
|
||||
|
||||
### The three error handling patterns in the codebase
|
||||
|
||||
**Pattern A — Silent return (the bug):** Error logged, no ACK sent, client hangs.
|
||||
|
||||
```go
|
||||
if err != nil {
|
||||
s.logger.Error("Failed to get ...", zap.Error(err))
|
||||
return // BUG: client gets no response, softlocks
|
||||
}
|
||||
```
|
||||
|
||||
**Pattern B — Log and continue (acceptable):** Error logged, handler continues and sends a success ACK with default/empty data. The client proceeds with fallback behavior.
|
||||
|
||||
```go
|
||||
if err != nil {
|
||||
s.logger.Error("Failed to load mezfes data", zap.Error(err))
|
||||
}
|
||||
// Falls through to doAckBufSucceed with empty data
|
||||
```
|
||||
|
||||
**Pattern C — Fail ACK (correct):** Error logged, explicit fail ACK sent. The client shows an appropriate error dialog and stays connected.
|
||||
|
||||
```go
|
||||
if err != nil {
|
||||
s.logger.Error("Failed to read rengoku_data.bin", zap.Error(err))
|
||||
doAckBufFail(s, pkt.AckHandle, nil)
|
||||
return
|
||||
}
|
||||
```
|
||||
|
||||
### Evidence that fail ACKs are safe
|
||||
|
||||
The codebase already sends ~70 `doAckSimpleFail`/`doAckBufFail` calls in production handler code across 15 files. The client handles them gracefully in all observed cases:
|
||||
|
||||
| File | Fail ACKs | Client behavior |
|
||||
|------|-----------|-----------------|
|
||||
| `handlers_guild_scout.go` | 17 | Guild recruitment error dialogs |
|
||||
| `handlers_guild_ops.go` | 10 | Permission denied, guild not found dialogs |
|
||||
| `handlers_stage.go` | 8 | "Room is full", "wrong password", "stage locked" |
|
||||
| `handlers_house.go` | 6 | Wrong password, invalid box index |
|
||||
| `handlers_guild.go` | 9 | Guild icon update errors, unimplemented features |
|
||||
| `handlers_guild_alliance.go` | 4 | Alliance permission errors |
|
||||
| `handlers_data.go` | 4 | Decompression failures, oversized payloads |
|
||||
| `handlers_festa.go` | 4 | Festival entry errors |
|
||||
| `handlers_quest.go` | 3 | Missing quest/scenario files |
|
||||
|
||||
A comment in `handlers_quest.go:188` explicitly documents the mechanism:
|
||||
|
||||
> sends doAckBufFail, which triggers the client's error dialog (snj_questd_matching_fail → SetDialogData) instead of a softlock
|
||||
|
||||
The original `mhfo-hd.dll` client reads the `ErrorCode` byte from `MsgSysAck` and dispatches to per-message error UI. A fail ACK causes the client to show an error dialog and remain functional. A missing ACK causes a softlock.
|
||||
|
||||
### Scope
|
||||
|
||||
A preliminary grep for `logger.Error` followed by bare `return` (no doAck call) found instances across ~25 handler files. However, a thorough manual audit (2026-02-20) revealed that the vast majority are Pattern B (log-and-continue to a success ACK with empty data) or Pattern C (explicit fail ACK). Only one true Pattern A instance was found, in `handleMsgSysOperateRegister` (`handlers_register.go`), which has been fixed.
|
||||
|
||||
**Status:** ~~Players experience softlocks on error paths.~~ **Fixed.** The last Pattern A instance (`handlers_register.go:62`) now sends `doAckBufSucceed` with nil data before returning. The ~87 existing `doAckSimpleFail`/`doAckBufFail` calls and the helper functions (`loadCharacterData`, `saveCharacterData`, `stubEnumerateNoResults`) provide comprehensive ACK coverage across all handler error paths.
|
||||
|
||||
---
|
||||
|
||||
## 3. No Architectural Layering — Handlers Do Everything
|
||||
|
||||
Handler functions directly embed raw SQL, binary parsing, business logic, and response building in a single function body. For example, a typical guild handler will:
|
||||
|
||||
1. Parse the incoming packet
|
||||
2. Run 3-5 inline SQL queries
|
||||
3. Apply business logic (permission checks, state transitions)
|
||||
4. Manually serialize a binary response
|
||||
|
||||
```go
|
||||
func handleMsgMhfCreateGuild(s *Session, p mhfpacket.MHFPacket) {
|
||||
pkt := p.(*mhfpacket.MsgMhfCreateGuild)
|
||||
|
||||
// Direct SQL in the handler
|
||||
var guildCount int
|
||||
err := s.Server.DB.QueryRow("SELECT count(*) FROM guilds WHERE leader_id=$1", s.CharID).Scan(&guildCount)
|
||||
if err != nil {
|
||||
s.logger.Error(...)
|
||||
return
|
||||
}
|
||||
|
||||
// Business logic inline
|
||||
if guildCount > 0 { ... }
|
||||
|
||||
// More SQL
|
||||
_, err = s.Server.DB.Exec("INSERT INTO guilds ...")
|
||||
|
||||
// Binary response building
|
||||
bf := byteframe.NewByteFrame()
|
||||
bf.WriteUint32(...)
|
||||
doAckSimpleSucceed(s, pkt.AckHandle, bf.Data())
|
||||
}
|
||||
```
|
||||
|
||||
There is no repository layer, no service layer — just handlers.
|
||||
|
||||
**Impact:** Testing individual concerns is impossible without a real database and a full session. Business logic can't be reused. Schema changes require updating dozens of handler files.
|
||||
|
||||
**Recommendation:** Introduce at minimum a repository layer for data access and a service layer for business logic. Handlers should only deal with packet parsing and response serialization.
|
||||
|
||||
---
|
||||
|
||||
## 4. ~~Magic Numbers Everywhere~~ (Substantially Fixed)
|
||||
|
||||
**Status:** Two rounds of extraction have replaced the highest-impact magic numbers with named constants:
|
||||
|
||||
- **Round 1** (commit `7c444b0`): `constants_quest.go`, `handlers_guild_info.go`, `handlers_quest.go`, `handlers_rengoku.go`, `handlers_session.go`, `model_character.go`
|
||||
- **Round 2**: `constants_time.go` (shared `secsPerDay`, `secsPerWeek`), `constants_raviente.go` (register IDs, semaphore constants), plus constants in `handlers_register.go`, `handlers_semaphore.go`, `handlers_session.go`, `handlers_festa.go`, `handlers_diva.go`, `handlers_event.go`, `handlers_mercenary.go`, `handlers_misc.go`, `handlers_plate.go`, `handlers_cast_binary.go`, `handlers_commands.go`, `handlers_reward.go`, `handlers_guild_mission.go`, `sys_channel_server.go`
|
||||
|
||||
**Remaining:** Unknown protocol fields (e.g., `handlers_diva.go:112-115` `0x19, 0x2D, 0x02, 0x02`) are intentionally left as literals until their meaning is understood. Data tables (monster point tables, item IDs) are data, not protocol constants. Standard empty ACK payloads (`make([]byte, 4)`) are idiomatic Go.
|
||||
|
||||
**Impact:** ~~New contributors can't understand what these values mean.~~ Most protocol-meaningful constants now have names and comments.
|
||||
|
||||
---
|
||||
|
||||
## 5. ~~Inconsistent Binary I/O Patterns~~ (Resolved)
|
||||
|
||||
**Status:** Non-issue on closer inspection. The codebase has already standardized on `byteframe` for all sequential packet building and parsing.
|
||||
|
||||
The 12 remaining `encoding/binary` call sites (across `sys_session.go`, `handlers_session.go`, `model_character.go`, `handlers_quest.go`, `handlers_rengoku.go`) are all cases where `byteframe` is structurally wrong:
|
||||
|
||||
- **Zero-allocation spot-reads on existing `[]byte`** — reading an opcode or ack handle from an already-serialized packet for logging, or sentinel guard checks on raw blobs. Allocating a byteframe for a 2-byte read in a log path would be wasteful.
|
||||
- **Random-access reads/writes at computed offsets** — patching fields in the decompressed game save blob (`model_character.go`) or copying fields within quest binaries during version backport (`handlers_quest.go`). Byteframe is a sequential cursor and cannot do `buf[offset:offset+4]` style access.
|
||||
|
||||
Pattern C (raw `data[i] = byte(...)` serialization) does not exist in production code — only in test fixtures as loop fills for dummy payloads.
|
||||
|
||||
---
|
||||
|
||||
## 6. ~~Session Struct is a God Object~~ (Accepted Design)
|
||||
|
||||
`sys_session.go` defines a `Session` struct (~30 fields) that every handler receives. After analysis, this is accepted as appropriate design for this codebase:
|
||||
|
||||
- **Field clustering is natural:** The ~30 fields cluster into 7 groups (transport, identity, stage, semaphore, gameplay, mail, debug). Transport fields (`rawConn`, `cryptConn`, `sendPackets`) are only used by `sys_session.go` — already isolated. Stage, semaphore, and mail fields are each used by 1-5 dedicated handlers.
|
||||
- **Core identity is pervasive:** `charID` is used by 38 handlers — it's the core identity field. Extracting it adds indirection for zero benefit.
|
||||
- **`s.server` coupling is genuine:** Handlers need 2-5 repos + config + broadcast, so narrower interfaces would mirror the full server without meaningful decoupling.
|
||||
- **Cross-channel operations use `Registry`:** The `Channels []*Server` field has been removed. All cross-channel operations (worldcast, session lookup, disconnect, stage search, mail notification) now go exclusively through the `ChannelRegistry` interface, removing the last direct inter-server coupling.
|
||||
- **Standard game server pattern:** For a game server emulator with the `func(s *Session, p MHFPacket)` handler pattern, Session carrying identity + server reference is standard design.
|
||||
|
||||
**Status:** Accepted design. The `Channels` field was removed and all cross-channel operations are routed through `ChannelRegistry`. No further refactoring planned.
|
||||
|
||||
---
|
||||
|
||||
## 7. ~~Mutex Granularity Issues~~ (Stage Map Fixed)
|
||||
|
||||
~~`sys_stage.go` and `sys_channel_server.go` use coarse-grained `sync.RWMutex` locks on entire maps:~~
|
||||
|
||||
```go
|
||||
// A single lock for ALL stages
|
||||
s.stageMapLock.Lock()
|
||||
defer s.stageMapLock.Unlock()
|
||||
// Any operation on any stage blocks all other stage operations
|
||||
```
|
||||
|
||||
The Raviente shared state uses a single mutex for all Raviente data fields.
|
||||
|
||||
**Status:** **Partially fixed.** The global `stagesLock sync.RWMutex` + `map[string]*Stage` has been replaced with a typed `StageMap` wrapper around `sync.Map`, providing lock-free reads and concurrent writes to disjoint keys. Per-stage `sync.RWMutex` remains for protecting individual stage state. The Raviente mutex is unchanged — contention is inherently low (single world event, few concurrent accessors).
|
||||
|
||||
---
|
||||
|
||||
## 8. Copy-Paste Handler Patterns
|
||||
|
||||
~~Many handlers follow an identical template with minor variations but no shared abstraction.~~ **Substantially fixed.** `loadCharacterData` and `saveCharacterData` helpers in `handlers_helpers.go` now cover all standard character blob load/save patterns (11 load handlers, 6 save handlers including `handleMsgMhfSaveScenarioData`). The `saveCharacterData` helper sends `doAckSimpleFail` on oversized payloads and DB errors, matching the correct error-handling pattern.
|
||||
|
||||
Remaining inline DB patterns were audited and are genuinely different (non-blob types, wrong tables, diff compression, read-modify-write with bit ops, multi-column updates, or queries against other characters).
|
||||
|
||||
---
|
||||
|
||||
## 9. Raw SQL Strings Scattered in Handlers
|
||||
|
||||
SQL queries are string literals directly embedded in handler functions with no constants, no query builder, and no repository abstraction:
|
||||
|
||||
```go
|
||||
err := s.Server.DB.QueryRow(
|
||||
"SELECT id, name, leader_id, ... FROM guilds WHERE id=$1", guildID,
|
||||
).Scan(&id, &name, &leaderID, ...)
|
||||
```
|
||||
|
||||
The same table is queried in different handlers with slightly different column sets and joins.
|
||||
|
||||
**Impact:** Schema changes (renaming a column, adding a field) require finding and updating every handler that touches that table. There's no way to ensure all queries stay in sync. SQL injection risk is low (parameterized queries are used), but query correctness is hard to verify.
|
||||
|
||||
**Recommendation:** At minimum, define query constants. Ideally, introduce a repository layer that encapsulates all queries for a given entity.
|
||||
|
||||
**Status:** ~~Substantially fixed.~~ ~~Nearly complete.~~ **Complete.** 21 repository files now cover all major subsystems: character, guild, user, house, tower, festa, mail, rengoku, stamp, distribution, session, gacha, event, achievement, shop, cafe, goocoo, diva, misc, scenario, mercenary. All guild subsystem tables (`guild_posts`, `guild_adventures`, `guild_meals`, `guild_hunts`, `guild_hunts_claimed`, `guild_alliances`) are fully migrated into `repo_guild.go`. Zero inline SQL queries remain in handler files — the last 5 were migrated to `charRepo.LoadSaveData`, `userRepo.BanUser`, `eventRepo.GetEventQuests`, and `eventRepo.UpdateEventQuestStartTimes`.
|
||||
|
||||

|
||||
|
||||
## 10. init() Function for Handler Registration
|
||||
|
||||
`handlers_table.go` uses a massive `init()` function to register ~200+ handlers in a global map:
|
||||
|
||||
```go
|
||||
func init() {
|
||||
handlers[network.MsgMhfSaveFoo] = handleMsgMhfSaveFoo
|
||||
handlers[network.MsgMhfLoadFoo] = handleMsgMhfLoadFoo
|
||||
// ... 200+ more entries
|
||||
}
|
||||
```
|
||||
|
||||
**Impact:** Registration is implicit and happens at package load time. It's impossible to selectively register handlers (e.g., for testing). The handler map can't be mocked. The `init()` function is ~200+ lines of boilerplate.
|
||||
|
||||
**Recommendation:** Use explicit registration (a function called from `main` or server setup) that builds and returns the handler map.
|
||||
|
||||
---
|
||||
|
||||
## 11. Panic-Based Flow in Some Paths
|
||||
|
||||
~~Some error paths use `panic()` or `log.Fatal()` (which calls `os.Exit`) instead of returning errors.~~ **Substantially fixed.** The 5 production `panic()` calls (4 in mhfpacket `Build()` stubs, 1 in binpacket `Parse()`) have been replaced with `fmt.Errorf` returns. The `byteframe.go` read-overflow panic has been replaced with a sticky error pattern (`ByteFrame.Err()`), and the packet dispatch loop in `sys_session.go` now checks `bf.Err()` after parsing to reject malformed packets cleanly.
|
||||
|
||||
**Remaining:** The `recover()` in `handlePacketGroup` is retained as a safety net for any future unexpected panics.
|
||||
|
||||
---
|
||||
|
||||
## 12. Inconsistent Logging
|
||||
|
||||
The codebase mixes logging approaches:
|
||||
|
||||
- `zap.Logger` (structured logging) — primary approach
|
||||
- Remnants of `fmt.Printf` / `log.Printf` in some packages
|
||||
- Some packages accept a logger parameter, others create their own
|
||||
|
||||
**Impact:** Log output format is inconsistent. Some logs lack structure (no fields, no levels). Filtering and aggregation in production is harder.
|
||||
|
||||
**Recommendation:** Standardize on `zap.Logger` everywhere. Pass the logger via dependency injection. Remove all `fmt.Printf` / `log.Printf` usage from non-CLI code.
|
||||
|
||||
---
|
||||
|
||||
## 13. ~~Tight Coupling to PostgreSQL~~ (Decoupled via Interfaces)
|
||||
|
||||
~~Database operations use raw `database/sql` with PostgreSQL-specific syntax throughout:~~
|
||||
|
||||
- ~~`$1` parameter placeholders (PostgreSQL-specific)~~
|
||||
- ~~PostgreSQL-specific types and functions in queries~~
|
||||
- ~~`*sql.DB` passed directly through the server struct to every handler~~
|
||||
- ~~No interface abstraction over data access~~
|
||||
|
||||
**Status:** **Fixed.** All 20 repository interfaces are defined in `repo_interfaces.go` (`CharacterRepo`, `GuildRepo`, `UserRepo`, `GachaRepo`, `HouseRepo`, `FestaRepo`, `TowerRepo`, `RengokuRepo`, `MailRepo`, `StampRepo`, `DistributionRepo`, `SessionRepo`, `EventRepo`, `AchievementRepo`, `ShopRepo`, `CafeRepo`, `GoocooRepo`, `DivaRepo`, `MiscRepo`, `ScenarioRepo`, `MercenaryRepo`). The `Server` struct holds interface types, not concrete types. Mock implementations in `repo_mocks_test.go` enable handler unit tests without PostgreSQL. SQL is still PostgreSQL-specific within the concrete `*Repository` types, but handlers are fully decoupled from the database.
|
||||

## Summary by Severity
|
||||
|
||||
| Severity | Anti-patterns |
|
||||
|----------|--------------|
|
||||
| **High** | ~~Missing ACK responses / softlocks (#2)~~ **Fixed**, no architectural layering (#3), ~~tight DB coupling (#13)~~ **Fixed** (21 interfaces + mocks) |
|
||||
| **Medium** | ~~Magic numbers (#4)~~ **Fixed**, ~~inconsistent binary I/O (#5)~~ **Resolved**, ~~Session god object (#6)~~ **Accepted design** (Channels removed, Registry-only), ~~copy-paste handlers (#8)~~ **Fixed**, ~~raw SQL duplication (#9)~~ **Complete** (21 repos, 0 inline queries remain) |
|
||||
| **Low** | God files (#1), ~~`init()` registration (#10)~~ **Fixed**, ~~inconsistent logging (#12)~~ **Fixed**, ~~mutex granularity (#7)~~ **Partially fixed** (stage map done, Raviente unchanged), ~~panic-based flow (#11)~~ **Fixed** |
|
||||
|
||||
### Root Cause
|
||||
|
||||
Most of these anti-patterns stem from a single root cause: **the codebase grew organically from a protocol reverse-engineering effort without introducing architectural boundaries**. When the primary goal is "make this packet work," it's natural to put the SQL, logic, and response all in one function. Over time, this produces the pattern seen here — hundreds of handler functions that each independently implement the full stack.
|
||||
|
||||
### Recommended Refactoring Priority
|
||||
|
||||
1. ~~**Add fail ACKs to silent error paths**~~ — **Done** (see #2)
|
||||
2. ~~**Extract a character repository layer**~~ — **Done.** `repo_character.go` covers ~95%+ of character queries
|
||||
3. ~~**Extract load/save helpers**~~ — **Done.** `loadCharacterData`/`saveCharacterData` in `handlers_helpers.go`
|
||||
4. ~~**Extract a guild repository layer**~~ — **Done.** `repo_guild.go` covers all guild tables including subsystem tables
|
||||
5. ~~**Define protocol constants**~~ — **Done** (see #4)
|
||||
6. ~~**Standardize binary I/O**~~ — already standardized on `byteframe`; remaining `encoding/binary` uses are correct (see #5)
|
||||
7. ~~**Migrate last 5 inline queries**~~ — **Done.** Migrated to `charRepo.LoadSaveData`, `userRepo.BanUser`, `eventRepo.GetEventQuests`, `eventRepo.UpdateEventQuestStartTimes`
|
||||
8. ~~**Introduce repository interfaces**~~ — **Done.** 20 interfaces in `repo_interfaces.go`, mock implementations in `repo_mocks_test.go`, `Server` struct uses interface types
|
||||
9. ~~**Reduce mutex contention**~~ — **Done.** `StageMap` (`sync.Map`-backed) replaces global `stagesLock`. Raviente mutex unchanged (low contention)

|
||||
|
||||
## 1. Fix swallowed errors with nil-dereference risk
|
||||
|
||||
**Priority:** High — latent panics triggered by any DB hiccup.
|
||||
|
||||
~30 sites use `_, _` to discard repo/service errors. Three are dangerous because the returned value is used without a nil guard:
|
||||
|
||||
| Location | Risk |
|
||||
|----------|------|
|
||||
| `handlers_guild_adventure.go:24,48,73` | `guild, _ := guildRepo.GetByCharID(...)` — no nil guard, will panic on DB error |
|
||||
| `handlers_gacha.go:56` | `fp, gp, gt, _ := userRepo.GetGachaPoints(...)` — balance silently becomes 0, enabling invalid transactions |
|
||||
| `handlers_house.go:167` | 7 return values from `GetHouseContents`, error discarded entirely |
|
||||
|
||||
Additional sites that don't panic but produce silently wrong data:
|
||||
|
||||
| Location | Issue |
|
||||
|----------|-------|
|
||||
| `handlers_distitem.go:35,111,129` | `distRepo.List()`/`GetItems()` errors become empty results, no logging |
|
||||
| `handlers_guild_ops.go:30,49` | `guildService.Disband()`/`Leave()` errors swallowed (nil-safe due to `result != nil` guard, but invisible failures) |
|
||||
| `handlers_shop.go:125,131` | Gacha type/weight lookups discarded |
|
||||
| `handlers_discord.go:34` | `bcrypt.GenerateFromPassword` error swallowed (only fails on OOM) |
|
||||
|
||||
**Fix:** Add error checks with logging and appropriate fail ACKs. For the three high-risk sites, add nil guards at minimum.
|
||||
|
||||
**Status:** **Done.** All swallowed errors fixed across 7 files:
|
||||
|
||||
- `handlers_guild_adventure.go` — 3 `GetByCharID` calls now check error and nil, early-return with ACK
|
||||
- `handlers_gacha.go` — `GetGachaPoints` now checks error and returns zeroed response; `GetStepupStatus` logs error
|
||||
- `handlers_house.go` — `GetHouseContents` now checks error and sends fail ACK; `HasApplication` moved inside nil guard to prevent nil dereference on `ownGuild`; `GetMission` and `GetWarehouseNames` now log errors
|
||||
- `handlers_distitem.go` — 3 `distRepo` calls now log errors
|
||||
- `handlers_guild_ops.go` — `Disband` and `Leave` service errors now logged
|
||||
- `handlers_shop.go` — `GetShopType`, `GetWeightDivisor`, `GetFpointExchangeList` now log errors
|
||||
- `handlers_discord.go` — `bcrypt.GenerateFromPassword` error now returns early with user-facing message
|
||||
|
||||
---
|
||||
|
||||
## 2. Fix bookshelf data pointer for three game versions
|
||||
|
||||
**Priority:** High — corrupts character save reads.
|
||||
|
||||
From `technical-debt.md`: `model_character.go:88,101,113` has `TODO: fix bookshelf data pointer` for G10-ZZ, F4-F5, and S6 versions. All three offsets are off by exactly 14810 vs the consistent delta pattern of other fields. Needs validation against actual save data.
|
||||
|
||||
**Fix:** Analyze save data from affected game versions to determine correct offsets. Apply fix and add regression test.
|
||||
|
||||
**Status:** Pending.
|
||||
|
||||
---
|
||||
|
||||
## 3. Add error feedback to parseChatCommand
|
||||
|
||||
**Priority:** Medium — improves operator experience with low effort.
|
||||
|
||||
`handlers_commands.go:71` is a 351-line switch statement dispatching 12 chat commands. Argument parsing errors (`strconv`, `hex.DecodeString`) are silently swallowed at lines 240, 256, 368, 369. Malformed commands silently use zero values instead of giving the operator feedback.
|
||||
|
||||
**Fix:** On parse error, send a chat message back to the player explaining the expected format, then return early. Each command's branch already has access to the session for sending messages.
|
||||
|
||||
**Status:** **Done.** All 4 sites now validate parse results and send the existing i18n error messages:
|
||||
|
||||
- `hex.DecodeString` (KeyQuest set) — sends kqf.set.error on invalid hex
|
||||
- `strconv.Atoi` (Rights) — sends rights.error on non-integer
|
||||
- `strconv.ParseInt` x/y (Teleport) — sends teleport.error on non-integer coords
|
||||
|
||||
---
|
||||
|
||||
## 4. Reconcile service layer docs vs reality
|
||||
|
||||
**Priority:** Medium — documentation mismatch causes confusion for contributors.
|
||||
|
||||
The CLAUDE.md architecture section shows a clean `handlers → svc_*.go → repo_*.go` layering, but in practice:
|
||||
|
||||
- **GuildService** has 7 methods. **GuildRepo** has 68. Handlers call `guildRepo` directly ~60+ times across 7 guild handler files.
|
||||
- The 4 services (`GuildService`, `MailService`, `AchievementService`, `GachaService`) were extracted for operations requiring cross-repo coordination (e.g., disband triggers mail), but the majority of handler logic goes directly to repos.
|
||||
|
||||
This isn't necessarily wrong — the services exist for multi-repo coordination, not as a mandatory pass-through.
|
||||
|
||||
**Fix:** Update the architecture diagram in `CLAUDE.md` to reflect the actual pattern: services are used for cross-repo coordination, handlers call repos directly for simple CRUD. Remove the implication that all handlers go through services. Alternatively, expand service coverage to match the documented architecture, but that is a much larger effort with diminishing returns.
|
||||
|
||||
**Status:** **Done.** Updated three files:
|
||||
|
||||
- `Erupe/CLAUDE.md` — Layered architecture diagram clarified ("where needed"), handler description updated to explain when to use services vs direct repo calls, added services table listing all 6 services with method counts and purpose, added "Adding Business Logic" section with guidelines
|
||||
- `server/CLAUDE.md` — Repository Pattern section renamed to "Repository & Service Pattern", added service layer summary with the 6 services listed
|
||||
- `docs/improvements.md` — This item marked as done
|
||||
|
||||
---
|
||||
|
||||
## 5. Consolidate GuildRepo mocks
|
||||
|
||||
**Priority:** Low — reduces friction for guild test authoring.
|
||||
|
||||
`repo_mocks_test.go` (1004 lines) has two separate GuildRepo mock types:
|
||||
|
||||
- `mockGuildRepoForMail` (67 methods, 104 lines) — used by mail tests
|
||||
- `mockGuildRepoOps` (38 methods, 266 lines) — used by ops/scout tests, with configurable behavior via struct fields
|
||||
|
||||
The `GuildRepo` interface has 68 methods. Neither mock implements the full interface. Adding any new `GuildRepo` method requires updating both mocks or compilation fails.
|
||||
|
||||
**Fix:** Merge into a single `mockGuildRepo` with all 68 methods as no-op defaults. Use struct fields (as `mockGuildRepoOps` already does for ~15 methods) for configurable returns in tests that need specific behavior.
|
||||
|
||||
**Status:** **Done.** Merged into a single `mockGuildRepo` (936 lines, down from 1004). All 12 test files updated. Adding a new `GuildRepo` method now requires a single stub addition.
|
||||
|
||||
---
|
||||
|
||||
## 6. Add mocks for 8 unmocked repo interfaces
|
||||
|
||||
**Priority:** Low — enables isolated handler tests for more subsystems.
|
||||
|
||||
8 of the 21 repo interfaces have no mock implementation: `TowerRepo`, `FestaRepo`, `RengokuRepo`, `DivaRepo`, `EventRepo`, `MiscRepo`, `MercenaryRepo`, `CafeRepo`.
|
||||
|
||||
Tests for those handlers either use stub handlers that skip repos or rely on integration tests. This limits the ability to write isolated unit tests.
|
||||
|
||||
**Fix:** Add no-op mock implementations for each, following the pattern established by existing mocks.
|
||||
|
||||
**Status:** **Done.** Added 8 mock implementations to `repo_mocks_test.go`: `mockTowerRepo`, `mockFestaRepo`, `mockRengokuRepo`, `mockDivaRepo`, `mockEventRepo`, `mockMiscRepo`, `mockMercenaryRepo`, `mockCafeRepo`. All follow the established pattern with no-op defaults and configurable struct fields for return values and errors.
|
||||
|
||||
---
|
||||
|
||||
## 7. Extract inline data tables from handler functions
|
||||
|
||||
**Priority:** Low — improves readability.
|
||||
|
||||
`handlers_items.go:18` — `handleMsgMhfEnumeratePrice` (164 lines) embeds two large `var` data blocks inline in the function body. These are static data tables, not logic.
|
||||
|
||||
**Fix:** Extract to package-level `var` declarations or a dedicated data file (following the pattern of `handlers_data_paper_tables.go`).
|
||||
|
||||
**Status:** **Done.** Extracted 3 inline data tables (LB prices, wanted list, GZ prices) and their anonymous struct types to `handlers_items_tables.go`. Handler function reduced from 164 to 35 lines.

## High Priority
|
||||
|
||||
### 1. Broken game features (gameplay-impacting TODOs)
|
||||
|
||||
These TODOs represent features that are visibly broken for players.
|
||||
|
||||
| Location | Issue | Impact |
|
||||
|----------|-------|--------|
|
||||
| `model_character.go:88,101,113` | `TODO: fix bookshelf data pointer` for G10-ZZ, F4-F5, and S6 versions | Wrong pointer corrupts character save reads for three game versions. Offset analysis shows all three are off by exactly 14810 vs the consistent delta pattern of other fields — but needs validation against actual save data. |
|
||||
| `handlers_achievement.go:125` | `TODO: Notify on rank increase` — always returns `false` | Achievement rank-up notifications are silently suppressed. Requires understanding what `MhfDisplayedAchievement` (currently an empty handler) sends to track "last displayed" state. |
|
||||
| `handlers_guild_info.go:443` | `TODO: Enable GuildAlliance applications` — hardcoded `true` | Guild alliance applications are always open regardless of setting. Needs research into where the toggle originates. |
|
||||
| `handlers_session.go:394` | `TODO(Andoryuuta): log key index off-by-one` | Known off-by-one in log key indexing is unresolved |
|
||||
| `handlers_session.go:535` | `TODO: This case might be <=G2` | Uncertain version detection in switch case |
|
||||
| `handlers_session.go:698` | `TODO: Retail returned the number of clients in quests` | Player count reported to clients does not match retail behavior |
|
||||
|
||||
### 2. Test gaps on critical paths
|
||||
|
||||
**All handler files now have test coverage.**
|
||||
|
||||
**Repository files with no store-level test file (17 total):**
|
||||
|
||||
`repo_achievement.go`, `repo_cafe.go`, `repo_distribution.go`, `repo_diva.go`, `repo_festa.go`, `repo_gacha.go`, `repo_goocoo.go`, `repo_house.go`, `repo_mail.go`, `repo_mercenary.go`, `repo_misc.go`, `repo_rengoku.go`, `repo_scenario.go`, `repo_session.go`, `repo_shop.go`, `repo_stamp.go`, `repo_tower.go`
|
||||
|
||||
These are validated indirectly through mock-based handler tests but have no SQL-level integration tests.
|
||||
|
||||
---
|
||||
|
||||
## Medium Priority
|
||||
|
||||
### 3. Logging anti-patterns
|
||||
|
||||
~~**a) `fmt.Sprintf` inside structured logger calls (6 sites):**~~ **Fixed.** All 6 sites now use `zap.Uint32`/`zap.Uint8`/`zap.String` structured fields instead of `fmt.Sprintf`.
|
||||
|
||||
~~**b) 20+ silently discarded SJIS encoding errors in packet parsing:**~~ **Fixed.** All call sites now use `SJISToUTF8Lossy()` which logs decode errors at `slog.Debug` level.
|
||||
|
||||
---
|
||||
|
||||
## Low Priority
|
||||
|
||||
### 4. CI updates
|
||||
|
||||
- ~~`codecov-action@v4` could be updated to `v5` (current stable)~~ **Removed.** Replaced with local `go tool cover` threshold check (no Codecov account needed).
|
||||
- ~~No coverage threshold is enforced — coverage is uploaded but regressions aren't caught~~ **Fixed.** CI now fails if total coverage drops below 50% (current: ~58%).
|
||||
|
||||
---
|
||||
|
||||
## Completed Items
|
||||
|
||||
Items resolved since the original audit:
|
||||
|
||||
| # | Item | Resolution |
|
||||
|---|------|------------|
|
||||
| ~~3~~ | **Sign server has no repository layer** | Fully refactored with `repo_interfaces.go`, `repo_user.go`, `repo_session.go`, `repo_character.go`, and mock tests. All 8 previously-discarded error paths are now handled. |
|
||||
| ~~4~~ | **Split `repo_guild.go`** | Split from 1004 lines into domain-focused files: `repo_guild.go` (466 lines, core CRUD), `repo_guild_posts.go`, `repo_guild_alliance.go`, `repo_guild_adventure.go`, `repo_guild_hunt.go`, `repo_guild_cooking.go`, `repo_guild_rp.go`. |
|
||||
| ~~6~~ | **Inconsistent transaction API** | All call sites now use `BeginTxx(context.Background(), nil)` with deferred rollback. |
|
||||
| ~~7~~ | **`LoopDelay` config has no Viper default** | `viper.SetDefault("LoopDelay", 50)` added in `config/config.go`. |
|
||||
| — | **Monthly guild item claim** (`handlers_guild.go:389`) | Now tracks per-character per-type monthly claims via `stamps` table. |
|
||||
| — | **Handler test coverage (4 files)** | Tests added for `handlers_session.go`, `handlers_gacha.go`, `handlers_plate.go`, `handlers_shop.go`. |
|
||||
| — | **Handler test coverage (`handlers_commands.go`)** | 62 tests covering all 12 commands, disabled-command gating, op overrides, error paths, raviente with semaphore, course enable/disable/locked, reload with players/objects. |
|
||||
| — | **Handler test coverage (`handlers_data_paper.go`)** | 20 tests covering all DataType branches (0/5/6/gift/>1000/unknown), ACK payload structure, earth succeed entry counts, timetable content, serialization round-trips, and paperGiftData table integrity. |
|
||||
| — | **Handler test coverage (5 files)** | Tests added for `handlers_seibattle.go` (9 tests), `handlers_kouryou.go` (7 tests), `handlers_scenario.go` (6 tests), `handlers_distitem.go` (8 tests), `handlers_guild_mission.go` (5 tests in coverage5). |
|
||||
| — | **Entrance server raw SQL** | Refactored to repository interfaces (`repo_interfaces.go`, `repo_session.go`, `repo_server.go`). |
|
||||
| — | **Guild daily RP rollover** (`handlers_guild_ops.go:148`) | Implemented via lazy rollover in `handlers_guild.go:110-119` using `RolloverDailyRP()`. Stale TODO removed. |
|
||||
| — | **Typos** (`sys_session.go`, `handlers_session.go`) | "For Debuging" and "offical" typos already fixed in previous commits. |
|
||||
| — | **`db != nil` guard** (`handlers_session.go:322`) | Investigated — this guard is intentional. Test servers run without repos; the guard protects the entire logout path from nil repo dereferences. Not a leaky abstraction. |
|
||||
|
||||
---
|
||||
|
||||
## Suggested Execution Order
|
||||
|
||||
Based on remaining impact:
|
||||
|
||||
1. ~~**Add tests for `handlers_commands.go`**~~ — **Done.** 62 tests covering all 12 commands (ban, timer, PSN, reload, key quest, rights, course, raviente, teleport, discord, playtime, help), disabled-command gating, op overrides, error paths, and `initCommands`.
|
||||
2. **Fix bookshelf data pointer** (`model_character.go`) — corrupts saves for three game versions (needs save data validation)
|
||||
3. **Fix achievement rank-up notifications** (`handlers_achievement.go:125`) — needs protocol research on `MhfDisplayedAchievement`
|
||||
4. ~~**Add coverage threshold** to CI~~ — **Done.** 50% floor enforced via `go tool cover` in CI; Codecov removed.
