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.
Users without a Go toolchain can now download pre-built binaries
directly from GitHub Releases (closes#161). The workflow triggers
on v* tags, builds Linux and Windows amd64 archives, and attaches
them along with SCHEMA.sql to an auto-generated release.
Also fixes the README badge URL (go-improved.yml → go.yml).
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.
Replace vague "Alpelo object system backport" references in CHANGELOG
and AUTHORS with accurate descriptions of the per-session object ID
allocation rework. Remove stale test comment referencing the deleted
NextObjectID method.
When a quest or scenario file was missing, handleMsgSysGetFile sent nil
data via doAckBufSucceed, which crashed the game client. Now sends
doAckBufFail so the client can handle the missing file gracefully.
Closes#109
Wrap *rand.Rand in a mutex-protected SafeRand type to make the global
RNG safe for concurrent use across goroutines. The previous bare
*rand.Rand caused data races detected by go test -race.
UTF8ToSJIS panicked when encountering characters outside the Shift-JIS
range (emoji, Lenny faces, cuneiform, etc.), crashing the server when
such characters were sent via the Discord relay channel.
Replace the panic with graceful filtering that drops unmappable runes
and preserves valid content. Also fix ToNGWord index-out-of-range panic
on empty encoder output.
Closes#116
