CharacterSaveData.Save() silently returned on failure (nil decompressed
data, compression error, DB error) while the caller unconditionally
logged "Saved character data successfully". This made diagnosing save
failures difficult (ref #163).
Save() now returns an error, and all six call sites check it. The
success log in saveAllCharacterData only fires when the save actually
persisted.
Eliminate the last three direct DB accesses from handler code:
- CharacterRepo.LoadSaveData: replaces db.Query in GetCharacterSaveData,
using QueryRow instead of Query+Next for cleaner single-row access
- EventRepo.GetEventQuests, UpdateEventQuestStartTime, BeginTx: moves
event quest enumeration and rotation queries behind the repo layer
- UserRepo.BanUser: consolidates permanent/temporary ban upserts into a
single method with nil/*time.Time semantics
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.
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
The protbot sent "DSGN:\x00" as the sign request type, but the server
strips the last 3 characters as a version suffix. Send "DSGN:041"
(ZZ client mode 41) to match the real client format.
The entrance channel entry parser read 14 bytes for remaining fields
but the server writes 18 bytes (9 uint16, not 7), causing a panic
when parsing the server list.
The channel server panicked on disconnect when a session had no
decompressed save data (e.g. protbot or early client disconnect).
Guard Save() against nil decompSave.
Also fix docker-compose volume mount for Postgres 18 which changed
its data directory layout.
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/.
Move SavePointer type/constants, CharacterSaveData struct, getPointers,
Compress, Decompress, and save data serialization methods out of
handlers_character.go into a dedicated model file.
Add explicit error discards (_ =) for Close() calls on network
connections, SQL rows, and file handles across 28 files. Also add
.golangci.yml with standard linter defaults to match CI configuration.
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.
