Add // stub: unimplemented to 70 empty game-feature handlers and
// stub: reserved to 56 protocol-reserved slots in handlers_reserve.go,
making them discoverable via grep. Add docs/unimplemented.md listing all
unimplemented handlers grouped by subsystem with descriptions.
Move scan loops from handlers into repository methods so that interfaces
return typed slices instead of leaking database cursors. This fixes
resource leaks (7 of 12 call sites never closed rows) and makes all
12 methods mockable for unit tests.
Affected repos: CafeRepo, ShopRepo, EventRepo, RengokuRepo, DivaRepo,
ScenarioRepo, MiscRepo, MercenaryRepo. New structs: DivaEvent,
MercenaryLoan, GuildHuntCatUsage. EventRepo.GetEventQuests left as-is
(requires broader Server refactor).
Several handlers discarded errors from rows.Scan() and db.Exec(),
masking data corruption or connection issues. Scan failures in diva
schedule, event quests, and trend weapons are now logged or returned.
InitializeWarehouse now surfaces its insert error to the caller.
The userBinary and minidata maps with their locks were spread across
Server as raw fields with manual lock management. Cross-channel session
searches also required acquiring nested locks (server lock + binary
lock). Encapsulating in dedicated types eliminates the nested locking
and reduces Server's field count by 4.
Move remaining raw s.server.db.* queries from handler files into
dedicated repository structs, completing the repository extraction
effort. Also adds SaveCharacterData and SaveHouseData to
CharacterRepository.
Fixes guild_hunts query to select both cats_used and start columns
to match the existing two-column Scan call. Adds slot index
validation in GoocooRepository to prevent SQL injection via
fmt.Sprintf.
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.
Add 18 new typed methods to CharacterRepository (ReadTime, SaveTime,
SaveInt, SaveBool, SaveString, ReadBool, ReadString, LoadColumnWithDefault,
SetDeleted, UpdateDailyCafe, ResetDailyQuests, ReadEtcPoints, ResetCafeTime,
UpdateGuildPostChecked, ReadGuildPostChecked, SaveMercenary, UpdateGCPAndPact,
FindByRastaID) and migrate ~56 inline SQL queries across 13 handler files.
Pure refactor — zero behavior change. Each handler produces identical SQL
with identical parameters. Cross-table JOINs and bulk CharacterSaveData
operations are intentionally left out of scope.
Add readCharacterInt/adjustCharacterInt helpers for single-column
integer operations on the characters table. Eliminates fmt.Sprintf
SQL construction in handlers_misc.go and replaces inline queries
across cafe, kouryou, and mercenary handlers.
Second round of protocol constant extraction: adds constants_time.go
(secsPerDay, secsPerWeek), constants_raviente.go (register IDs,
semaphore constants), and named constants across 14 handler files
replacing raw hex/numeric literals. Updates anti-patterns doc to
mark #4 (magic numbers) as substantially fixed.
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
Several handlers used packet fields as array indices or SQL column
names without bounds checking, allowing crafted packets to panic the
server or produce malformed SQL.
Panic fixes (high severity):
- handlers_mail: bounds check AccIndex against mailList length
- handlers_misc: validate ArmourID >= 10000 and MogType <= 4
- handlers_mercenary: check RawDataPayload length before slicing
- handlers_house: check RawDataPayload length in SaveDecoMyset
- handlers_register: guard empty RawDataPayload in OperateRegister
SQL column name fixes (medium severity):
- handlers_misc: early return on unknown PointType
- handlers_items: reject unknown StampType in weekly stamp handlers
- handlers_achievement: cap AchievementID at 32
- handlers_goocoo: skip goocoo.Index > 4
- handlers_house: cap BoxIndex for warehouse operations
- handlers_tower: fix MissionIndex=0 bypassing normalization guard
UserBinary type1-5 and EnhancedMinidata are transient session state
resent by the client on every login. Persisting them to the DB on
every set was unnecessary I/O. Both are now served exclusively from
server-scoped in-memory maps (userBinaryParts, minidataParts).
Includes a schema migration to drop the now-unused type2/type3
columns from user_binary and minidata column from characters.
Ref #158
Add package-level documentation (doc.go) to all 22 first-party
packages and godoc comments to ~150 previously undocumented
exported symbols across common/, network/, and server/.
