Replace the five-goroutine session model (RunDialer, RunKeepalive,
RunReader, RunHeartbeatForwarder, RunStopMonitor, Session) with a single
DefaultWorker.runSession method containing two select loops: one
pre-connection and one connected. Ephemeral dial goroutines replace
RunDialer; the keepalive timer and heartbeat reset are inlined. No
exported building-block symbols remain.
Consolidate worker_dialer_test.go, worker_session_test.go, and
worker_start_test.go into worker_test.go. Add seven new behavioral
tests covering dial failure, keepalive-driven dial replacement,
pre-connection stop, message delivery with timestamp, sustained
activity and pong resetting the keepalive timer, keepalive-triggered
reconnect, and nil connection pointer after disconnect.
Update EXTEND.md and README.md to remove references to the deleted
building blocks and document the single worker replacement pattern
Replaces the flat key-value logging scheme with component-based structured
logging via go-mana-component. Each layer (pool, worker, connection) builds
its own component identity and derives a *slog.Logger from a caller-supplied
slog.Handler.
- Delete logging/ package (logging.go, logging_test.go)
- Strip LoggingEnabled and LogLevel from ConnectionConfig, PoolConfig,
WorkerConfig; remove associated option funcs
- Change NewConnection and NewConnectionFromSocket to accept ctx and
slog.Handler instead of *slog.Logger; constructors build component
identity via MustNew/MustExtend internally
- Change WorkerFactory, NewWorker, connect, and RunDialer to carry
slog.Handler; remove PoolPlugin.Handler
- Change NewPool to establish pool component identity via MustNew;
remove pool_id field, PoolPlugin.ID, and ErrInvalidPoolID
- Fix data race in MockSlogHandler: WithAttrs now shares parent mutex
pointer rather than allocating a new one per child
- Run go fix
