Centralizes all 31 direct users-table SQL queries from 11 handler
files into a single UserRepository, following the same pattern as
CharacterRepository and GuildRepository. The only excluded query is
the sign_sessions JOIN in handleMsgSysLogin which spans multiple
tables.
Silently ignored DB errors in handlers could cause data loss (frontier
point transactions completing without DB writes), reward duplication
(stamp exchange granting items on failed UPDATE), and crashes (tower
mission page=0 causing index-out-of-bounds). House access state
defaulting to 0 on DB failure also bypassed all access controls.
HIGH risk fixes:
- frontier point buy/sell now fails with ACK on DB error
- stamp exchange/stampcard abort on failed UPDATE
- guild meal INSERT returns fail ACK instead of orphaned ID 0
- mercenary/airou creation aborts on failed sequence nextval
MEDIUM risk fixes:
- tower mission page clamped to >= 1 preventing array underflow
- tower RP donation returns early on failed guild state read
- house state defaults to 2 (password-protected) on DB failure
- playtime read failure logged instead of silently resetting RP
Also cache userID on Session at login time, eliminating ~25 redundant
subqueries of the form WHERE u.id=(SELECT c.user_id FROM characters
c WHERE c.id=$1) across shop, gacha, command, and distitem handlers.
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
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/.
138 bare db.Exec calls across 22 handler files silently dropped write
errors. Each is now wrapped with error check and zap logging.
4 QueryRow sites that legitimately return sql.ErrNoRows during normal
operation (new player mezfes, festa rankings, empty guild item box)
now filter it out to reduce log noise.
Fix unchecked error returns on bf.Seek(), db.Exec(), QueryRow().Scan(),
pkt.Build(), logger.Sync(), and binary.Write() calls. The linter now
passes with 0 errors, build compiles, and all tests pass with -race.
