Add ShutdownAndDrain to the channel server (issue #179 non-breaking
subset): on SIGTERM/SIGINT, force-close all active sessions so that
logoutPlayer runs for each one (saves character data, cleans up stages
and semaphores), then poll until the session map empties or a 30-second
context deadline passes. Existing Shutdown() is unchanged.
Add ShutdownCountdownSeconds int config field (default 10) alongside
DisableSoftCrash so operators can tune the broadcast countdown without
patching code. A zero value falls back to 10 for safety.
Fix pre-existing test failures: MsgMhfAddRewardSongCount has a complete
Parse() implementation so it no longer belongs in the "NOT IMPLEMENTED"
parse test list; its handler test is updated to pass a real packet and
assert an ACK response instead of calling with nil.
A second Ctrl+C/SIGINT while the 10-second shutdown countdown is
running now exits immediately instead of being silently dropped.
The signal channel is buffered to 2 so the second signal is captured,
and the countdown select exits via os.Exit(1) on receipt.
The catch-up migration now creates the servers table if missing, like
sign_sessions. Startup cleanup queries in main.go use Exec instead of
MustExec so missing tables log warnings rather than panicking.
Instead of a generic "Failed to ping" message, detect the actual
cause and show a targeted fix:
- net error → PostgreSQL not reachable, check if it's running
- pq 28P01 → wrong password, update config.json
- pq 3D000 → database doesn't exist, create it
An MMO server without multiplayer defeats the purpose. PostgreSQL
is the right choice and Docker Compose already solves the setup
pain. This reverts the common/db wrapper, SQLite schema, config
Driver field, modernc.org/sqlite dependency, and all repo type
changes while keeping the dashboard, wizard, and CI improvements
from the previous commit.
Add zero-dependency SQLite mode so users can run Erupe without
PostgreSQL. A transparent db.DB wrapper auto-translates PostgreSQL
SQL ($N placeholders, now(), ::casts, ILIKE, public. prefix,
TRUNCATE) for SQLite at runtime — all 28 repo files use the wrapper
with no per-query changes needed.
Setup wizard gains two new steps: quest file detection with download
link, and gameplay presets (solo/small/community/rebalanced). The API
server gets a /dashboard endpoint with auto-refreshing stats.
CI release workflow now builds and pushes Docker images to GHCR
alongside binary artifacts on tag push.
Key changes:
- common/db: DB/Tx wrapper with 6 SQL translation rules
- server/migrations/sqlite: full SQLite schema (0001-0005)
- config: Database.Driver field ("postgres" or "sqlite")
- main.go: SQLite connection with WAL mode, single writer
- server/setup: quest check + preset selection steps
- server/api: /dashboard with live stats
- .github/workflows: Docker in release, deduplicate docker.yml
Extract a Session interface from *discordgo.Session so DiscordBot methods
can be tested with a mock — no live Discord connection required. Add
AddHandler, RegisterCommands, and UserID methods to DiscordBot so
external callers (main.go, sys_channel_server.go) no longer reach
through bot.Session directly. Rewrite tests with a mockSession,
raising discordbot coverage from 12.5% to 66.7%.
- Add Language default ("jp") so missing field no longer produces empty
string, and include language selector in setup wizard
- Add --setup flag to re-run wizard even when config.json exists,
providing a recovery path for corrupted configs
- Auto-apply seed data on fresh databases so users who skip the wizard
still get shops, events, and gacha
- Fix stale docs referencing non-existent init/setup.sh and
schemas/patch-schema/ in docker/README, CONTRIBUTING, and README
Replace 4 independent schema management code paths (Docker shell
script, setup wizard pg_restore, test helpers, manual psql) with a
single migration runner embedded in the server binary.
The new server/migrations/ package uses Go embed to bundle all SQL
schemas. On startup, Migrate() creates a schema_version tracking
table, detects existing databases (auto-marks baseline as applied),
and runs pending migrations in transactions.
Key changes:
- Consolidated init.sql + 9.2-update + 33 patches into 0001_init.sql
- Setup wizard simplified to single "Apply schema" checkbox
- Test helpers use migrations.Migrate() instead of pg_restore
- Docker no longer needs schema volume mounts or init script
- Seed data (shops, events, gacha) embedded and applied via API
- Future migrations just add 0002_*.sql files — no manual steps
When config.json is missing, Erupe now launches a temporary HTTP server
on port 8080 serving a guided setup wizard instead of exiting with a
cryptic error. The wizard walks users through database connection,
schema initialization (pg_restore + SQL migrations), and server settings,
then writes config.json and continues normal startup without restart.
- Warn at startup when quest files are missing (clients crash without
them) and point users to the download link
- Fix Host config description: it's the advertised IP, not a bind
address — 0.0.0.0 was wrong advice
- Load bundled schemas (shops, events, gacha) in Docker init so new
users get working demo data out of the box
- Renumber duplicate patch schema 28 → 32 to resolve numbering
collision
- Fix patch schema example filename to use hyphens matching actual
files
main.go always sets both Channels and Registry together, making the
Channels fallback paths dead code. This removes:
- Server.Channels field from the Server struct
- 3 if/else fallback blocks in handlers_session.go (replaced with
Registry.FindChannelForStage, SearchSessions, SearchStages)
- 1 if/else fallback block in handlers_guild_ops.go (replaced with
Registry.NotifyMailToCharID)
- 3 method fallbacks in sys_channel_server.go (WorldcastMHF,
FindSessionByCharID, DisconnectUser now delegate directly)
Updates anti-patterns.md #6 to "accepted design" — Session struct is
appropriate for this game server's handler pattern, and cross-channel
coupling is now fully routed through the ChannelRegistry interface.
The config package used `package _config` with a leading underscore,
which is unconventional in Go. Rename to `package config` (matching the
directory name) and use `cfg` as the standard import alias across all
93 importing files.
sqlx.Open was called with no pool configuration, risking PostgreSQL
connection exhaustion under load. Set max open/idle conns and lifetimes.
CreatePost INSERT + soft-delete UPDATE were two separate queries with
no transaction, risking inconsistent state on partial failure.
CollectAdventure used SELECT then UPDATE without a lock, allowing
concurrent guild members to double-collect. Now uses SELECT FOR UPDATE
within a transaction.
Replace the mutable global `_config.ErupeConfig` with dependency
injection across 79 files. Config is now threaded through existing
paths: `ClientContext.RealClientMode` for packet encoding, `s.server.
erupeConfig` for channel handlers, and explicit parameters for utility
functions. This removes hidden coupling, enables test parallelism
without global save/restore, and prevents low-level packages from
reaching up to the config layer.
Key changes:
- Enrich ClientContext with RealClientMode for packet files
- Add mode parameter to CryptConn, mhfitem, mhfcourse functions
- Convert handlers_commands init() to lazy sync.Once initialization
- Delete global var, init(), and helper functions from config.go
- Update all tests to pass config explicitly
Enable multiple Erupe instances to share a single PostgreSQL database
without destroying each other's state, fix existing data races in
cross-channel access, and lay groundwork for future distributed
channel server deployments.
Phase 1 — DB safety:
- Scope DELETE FROM servers/sign_sessions to this instance's server IDs
- Fix ci++ bug where failed channel start shifted subsequent IDs
Phase 2 — Fix data races in cross-channel access:
- Lock sessions map in FindSessionByCharID and DisconnectUser
- Lock stagesLock in handleMsgSysLockGlobalSema
- Snapshot sessions/stages under lock in TransitMessage types 1-4
- Lock channel when finding mail notification targets
Phase 3 — ChannelRegistry interface:
- Define ChannelRegistry interface with 7 cross-channel operations
- Implement LocalChannelRegistry with proper locking
- Add SessionSnapshot/StageSnapshot immutable copy types
- Delegate WorldcastMHF, FindSessionByCharID, DisconnectUser to Registry
- Migrate LockGlobalSema and guild mail handlers to use Registry
- Add comprehensive tests including concurrent access
Phase 4 — Per-channel enable/disable:
- Add Enabled *bool to EntranceChannelInfo (nil defaults to true)
- Skip disabled channels in startup loop, preserving ID stability
- Add IsEnabled() helper with backward-compatible default
- Update config.example.json with Enabled field
Re-enable the golangci-lint job in CI (disabled Oct 2025), update to
Go 1.25 and golangci-lint-action v7. Fix errcheck, gosimple S1009,
staticcheck SA4031 and SA2001 errors across 54 files. Remaining ~39
lint errors will be addressed in follow-up commits.
Move time utilities (TimeAdjusted, TimeMidnight, TimeWeekStart, TimeWeekNext,
TimeGameAbsolute) from channelserver into common/gametime to break the
inappropriate dependency where signserver, entranceserver, and api imported
the 38K-line channelserver package just for time functions.
Replace all fmt.Printf debug logging in sys_session.go and handlers_object.go
with structured zap logging for consistent observability.
