diana 0.15.1

Spring-inspired, annotation-driven backend framework for Dart: compile- time dependency injection, declarative controllers, middleware and validation.

Changelog

0.15.1

• Package metadata for pub.dev: MIT license, repository/documentation links, topics, and an example/.
• xml constraint now admits 7.x.
• Shorter pub.dev description; dart format applied (no behavior change).

0.15.0

• Version bump only (kept in lockstep with the workspace).

0.14.0

• STOMP 1.2 over WebSockets (stomp/frame.dart, stomp/broker.dart): a StompFrame codec, an in-memory StompBroker, the StompEndpoint base, StompPublisher, StompMessage and StompRelayEvent. Topic publishes relay across isolates through the event bus.

0.13.0

• Version bump only (kept in lockstep with the workspace).

0.12.0

• New dependency-free CronExpression (cron.dart): 6-field Spring-style parser with macros, nextAfter in local time. DianaScheduler.schedule gains a cron parameter (exactly one of fixedRate/fixedDelay/cron); cron runs are re-armed after completion so they never overlap.

0.11.0

• New pluggable @Cacheable backend contract in aspects.dart: DianaCacheStore (wrap-style run<V>(spec, key, miss)), CacheSpec, and InMemoryCacheStore (the exposed per-isolate default).

0.10.0

• New aspect runtime (aspects.dart): runTimed, MethodCache (TTL+LRU, single-flight, errors never cached), RetryPolicy, CircuitBreakerPolicy and CircuitOpenException — the helpers behind the generated $Aspect$X proxies. DianaObserver gains the observeTimedMethod no-op hook.

0.9.0

• Request body size limit: server.maxBodyBytes (default 10 MiB) caps every non-multipart body read through DianaRequest with streaming enforcement (413); server.multipart.maxSize now bounds the raw multipart stream, part headers included.
• Shutdown drains in-flight remote-event dispatches before dispose(); dispatchRemote tolerates listeners registered mid-dispatch. Hijacked streaming responses send a real reason phrase and strip CR/LF from header values.
• Multi-isolate startup is coordinated and fail-closed: no isolate serves until all are initialized, and a startup failure shuts down already-spawned workers before rethrowing.

0.8.1

• Multi-isolate shutdown never hangs: worker dispose failures are reported, hung workers are killed after DianaRuntime.workerShutdownTimeout, dead worker isolates are detected and skipped. Scheduler: no more Timer leak on fixedDelay re-arms; synchronous task throws reach onError. Multipart fields decode as UTF-8; zero-length chunks no longer truncate streamed responses; SSE source errors stop the heartbeat; denied CORS responses carry Vary: Origin; the event bus tolerates listeners registered mid-dispatch.

0.8.0

• Added the neutral DianaObserver contract (observer.dart) and threaded an optional observer through DianaServer, DianaScheduler and DianaEventBus; DianaScheduler.schedule gained name. New livenessEndpointHandler/readinessEndpointHandler.

0.7.0

• DianaScheduler.schedule gains perIsolate (default false): with multi-isolate serving, leader-only tasks are skipped in worker isolates so a schedule runs once per process. New DianaRuntime.isWorkerIsolate (set before a worker's bootstrap runs).

0.6.0

• Version bump only (kept in lockstep with the workspace; diana_data builds on this release).

0.5.0

• Added principalAttributeKey and bindPrincipal<T>(DianaRequest) to binding.dart — the cross-package contract used by diana_auth's authentication middleware and by generated @Principal() adapters.

0.4.0

• Application events: DianaEventPublisher (injectable interface) and DianaEventBus — awaited local dispatch in registration order with subtype matching (publish), plus broadcast for cross-isolate delivery.
• DianaRuntime bridges broadcast events hub-and-spoke across worker isolates (exactly-once per isolate); DianaRunnable gains an optional eventBus. Unsendable broadcast events fail fast with ArgumentError.

0.3.0

• Content negotiation: pluggable BodyCodec interface with a BodyCodecRegistry; codecs are discovered through DI (any singleton implementing BodyCodec). New helpers decodeMapBody/decodeListBody (415/400 semantics) and negotiatedResponse (Accept-driven, 406 via NotAcceptableException).
• XML out of the box: XmlCodec (application/xml, text/xml) with a documented Map↔XML convention — register it with @Component() class AppXmlCodec extends XmlCodec {}.
• Server-Sent Events: ServerSentEvent (+ .json), spec-compliant encoder (encodeSse, id/event/retry/multi-line data, heartbeats) and sseResponse. Streamed responses use DianaResponse.stream with a new bodyStream field; the relic adapter serves them over a hijacked socket with chunked framing so events flush immediately.
• New config key server.sse.heartbeatSeconds (default 15, 0 disables).
• DianaRequest now carries the codec registry (codecs) alongside limits.

0.2.0

• Application lifecycle: @PostConstruct/@PreDestroy, DianaApp, DianaRuntime.run with graceful shutdown, DianaOverrides for tests.
• Configuration profiles, typed lists and section().
• HTTPS (TLS) and experimental multi-isolate serving.
• CORS (@CrossOrigin, global config, automatic preflight).
• Static file serving with SPA fallback.
• Multipart uploads, raw String bodies and 406 Accept negotiation.
• Native JSON codegen (@Json/@JsonField).
• OpenAPI 3 document generation and /openapi.json.
• Actuator endpoints /actuator/health and /info.
• @Scheduled tasks (fixedRate/fixedDelay).
• WebSocket handshake interceptors.

0.1.0

• Initial release: compile-time DI, controllers/routing on relic, parameter/body binding, DTO validation, middleware chains, configuration, HttpException hierarchy with @ControllerAdvice, WebSocket support.
