RE'd putDisplayed_achievement from ZZ client DLL via Ghidra: the packet
sends opcode + 1 zero byte with no achievement ID, acting as a blanket
"I saw everything" signal.
Server changes:
- Track per-character last-displayed levels in new displayed_levels
column (migration 0008)
- GetAchievement compares current vs displayed levels per entry
- DisplayedAchievement snapshots current levels to clear notifications
- Repo, service, mock, and 3 new service tests
Protbot changes:
- New --action achievement: fetches achievements, shows rank-up markers,
sends DISPLAYED_ACHIEVEMENT, re-fetches to verify notifications clear
- Packet builders for GET/ADD/DISPLAYED_ACHIEVEMENT
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]
Alliance applications were hardcoded to always-open. Add a `recruiting`
column to guild_alliances and handle OperateJoint actions 0x06 (Allow)
and 0x07 (Deny) confirmed via Wii U debug symbols. Only the parent
guild leader can toggle the setting, matching the existing disband guard.
Filed #164-#168 for all 8 remaining TODOs. Added Tracker column
with issue links, fixed stale line numbers, added MhfAddUdPoint
stub entry, and expanded the suggested execution order.
Codecov requires an account and token to function. Replace it with
a self-contained `go tool cover` step that fails the build if total
coverage drops below 50% (currently ~58%). This catches test
regressions without external service dependencies.
The 5 remaining handler files (seibattle, kouryou, scenario, distitem,
guild_mission) were already covered by commit 6c0269d but the doc
was not updated at the time.
Add 30 new tests to handlers_commands_test.go covering previously
untested paths: raviente with semaphore (start, multiplier, ZZ-only
sed/res commands, version gating), course enable/disable/locked/alias,
reload with other players and objects, help filtering for non-op vs op,
ban error paths and long-form duration aliases, and disabled-command
gating for all 12 commands. Total: 62 tests, all passing with -race.
The guild daily RP rollover TODO in handlers_guild_ops.go was stale —
the feature was already implemented via lazy rollover in
handlers_guild.go. Several other items in technical-debt.md were also
resolved in prior commits (typos, db guard investigation). Updated
the doc to reflect current state and bumped codecov-action to v5.
Add SJISToUTF8Lossy() that wraps SJISToUTF8() and logs decode errors at
slog.Debug level. Replace all 31 call sites across 17 files that previously
discarded the error with `_, _ =`. This makes garbled text from malformed
SJIS client data debuggable without adding noise at default log levels.
Replace db.Begin() with db.BeginTxx(context.Background(), nil) across all
8 remaining call sites in repo_guild.go, repo_guild_rp.go, repo_festa.go,
and repo_event.go. Use deferred Rollback() instead of explicit rollback
at each error return, eliminating 15 manual rollback calls.
Players could never claim monthly guild items because the handler
always returned 0x01 (claimed). Now tracks per-character per-type
(standard/HLC/EXC) claim timestamps in the stamps table, comparing
against the current month boundary to determine claim eligibility.
Adds MonthStart() to gametime, extends StampRepo with
GetMonthlyClaimed/SetMonthlyClaimed, and includes schema migration
31-monthly-items.sql.
fmt.Sprintf inside zap logger calls defeats structured logging,
making log aggregation and filtering harder. All 6 sites now use
proper zap fields (zap.Uint32, zap.Uint8, zap.String).
LoopDelay had no viper.SetDefault, so omitting it from config.json
caused a zero-value (0 ms) busy-loop in the recv loop. Default is
now 50 ms, matching config.example.json.
