rpc_dart_framework 0.3.3

Client and server framework for rpc_dart — modules, DI, lifecycle, graceful shutdown, rate limiting, isolate workers, and test harness.

0.3.3

Fixes (audit):

• RpcApp._setupEndpoint no longer swallows a buildContracts() failure. Previously a throwing buildContracts was logged and ignored, then endpoint.start() ran anyway, leaving a live endpoint missing its services (clients got "method not found" instead of a startup failure). The error is now logged with context and rethrown, so start() aborts and the normal rollback runs; endpoint.start() is not reached.
• RpcApp.start() is now single-shot. Previously, after a failed start, calling start() again re-entered and reassigned the late final lifecycle fields (_modules, _container, _env, _autoInterceptors), throwing LateInitializationError and masking the original failure. A failed start now surfaces the ORIGINAL exception, and any later start() (after success or failure) throws a clear StateError ("RpcApp.start() can only be called once; create a new RpcApp to restart."). Note: true restart of an RpcApp instance was never supported (the lifecycle fields are late final); create a new instance to restart.

0.3.2

• Fixed RpcAppConfig.logController not being wired to endpoints -- context.log now works in responder handlers when logController is set in config.

Fixes (audit):

• RpcApp.start() now rolls back on a partial startup failure: already-started modules get onStop(), the transport server is stopped, and spawned isolates are terminated (in reverse order) before the error is rethrown. Previously these resources leaked and the app could not be restarted.
• health() now factors endpoint health into the overall RpcAppHealthLevel -- an inactive/closed endpoint degrades the app to unhealthy instead of reporting healthy.
• RpcContainer.tryGet<T>() no longer swallows a StateError thrown inside a registered factory (it now checks has<T>() first), so factory failures propagate instead of being misreported as "not registered".

New API:

• RpcContainer.registerLazySingleton<T>() -- memoizes a single shared instance on first get() (registerFactory keeps its per-call semantics).
