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.
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.
A malicious or buggy client could send arbitrarily large payloads
that get written directly to PostgreSQL, wasting disk and memory.
Each save handler now rejects payloads exceeding a generous upper
bound derived from the known data format sizes.
Covers all remaining items from #158: partner, hunternavi,
savemercenary, scenariodata, platedata, platebox, platemyset,
rengokudata, mezfes, savefavoritequest, house_furniture, mission.
Closes#158
