Lobby search now returns only quest-bound players (QuestReserved) instead
of all reserved slots, matching retail behavior. The new field is
pre-collected under server lock before stage iteration to respect
Server.Mutex → Stage.RWMutex lock ordering.
Replaced three TODOs with RE documentation from Ghidra decompilation of
mhfo-hd.dll ZZ:
- Log key off-by-one: putRecord_log/putTerminal_log pass size 0 for the
key field in ZZ, so the stored key is unused beyond issuance
- User search padding: ZZ per-entry parser confirms 40-byte block via
memcpy(dst, src+8, 0x28); G2 DLL analysis inconclusive (stripped)
- Player count: field at entry offset 0x08 maps to struct param_1[0xe]
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
