Qbit Versions Save

QBit Java Reactive Microservices Lib.

Updated to match Reakt 1.0.0.RELEASE. You can now use Reakt Reactor instead of QBit Reactor on new projects.

This is mostly to fix an issue with the maven pom that was introduced in the QBit Release 0.9.4. There is also some code formatting.

QBit Java Reactive Microservices Lib Release 0.9.4.

Added support for Reakt and started using it. Also changed QBit Callbacks to be more compatible with Reakt Callbacks to make the transition easier.

• 660 Report back HttpClient connection issues
• Implemented new Vertx EventBus bridge so QBit Microservice lib services can be called over the event bus.
• 659 Improved WebSocket connection open handling of QBit microservices exposed over websocket
• 656 Added Reactor One Shot task

        /* Add a task that repeats every ten seconds. */
        reactor.addOneShotAfterTask(10, TimeUnit.SECONDS, () -> {
            test.set(true);
            count.incrementAndGet();
        });

• 635 Improved Dispatch so creating things like Vertx EventBus bridge to QBit Microservices Lib possible
• 631 Improved Serialization JSON strictness
• 620 Added ability to filter requests before body is read to do things like filter on HttpRequest body size
• 618 Fixed Hibernate Annotation breaking QBit problem
• 614 Filters for HttpRequest and HttpResponse was added to support things like CORS response filters
• 610 WebSocket RPC call fixes
• Implemented Reactive Streams support
• 591 Fixed form handling issue when running embedded in Vertx instead of using Vertx as lib
• 589 JSON list serialization was not working with nulls in list properly
• 587 implement form params as part of http request
• 586 issue warning if there is an attempt to create an interface with a blocking cal
• 583 ServiceQueue should empty queue on stop
• 582 EventManager.joinService needs a corresponding EventManager.leaveService
• 576 addResponseDecorator is creating duplicate http headers
• 575 of NoCache Header entry increments in every request if @NoCacheHeader is uses.
• 574 missing uri params was throwing an index out of bounds exception
• 571 improved health system so it is fit to track errors and report them to monitoring systems
• Added MDC support so that REST/WebSocket services can pass Logging MDC support to other downstream services. Request headers, request id, request info, etc. can be tracked in log to track down log message to originating request. See MDC support documents. There were several Github issues/tasks with this effort. MDC is essential for reactive Java Microservices.

final ManagedServiceBuilder managedServiceBuilder = managedServiceBuilder().setRootURI("/");

managedServiceBuilder.enableLoggingMappedDiagnosticContext();

• 533 Added base service class that takes a reactor, timer and statsCollector
• 529 Map<String, Object> does not allow deeply nested lists and maps for JSON serialization / deserialization
• 528 Take out hostname as an option for StatsReplication (some stats system encode the host name, some don't)

• 499 Create websocket service client (ClientFactory) that is ServiceDiscovery aware

• Admin: Added support for suggest GC.
• Queue: Added warning messages if queue has not been started and you are sending items to a stopped queue
• Health: Added a info message if you start more than one health system, and debug support.
• Spring: Fixed bug with not starting health service
• REST: Added @HideMethod annotation. Any method annotated with @HideMethod will not show up as REST end point, and will not be processes by Swagger.
• Added chained predicates support for HttpServer
• Admin: Fixed issue with stats for Heroku
• Added better URI param handling (issue fixed resource handling with URI params)
• Issue fixed with callback from REST (not getting sent to client). BoonServiceMethodCallHandler was missing onTimeout and onError. (Bug fix)
• Admin GC stats collection and GC stat count fixed
• (EndpointServer, REST support, HttpServer) Finished with response decorator and handling response in a callback.
• Added spring support for discovery and construction os QBit Services
• Added javax.inject support

• Admin: Added Buffered StatsCollector for performance of stats collection
• Admin: Wrapped construction of stats collector with statscollectorbuffer
• Added better error handling: QBit does not support method overloading and should give a warning instead of failing silently
• Admin: Added support for more endpoints about the OS and VM for debugging.
• Admin: Added password screen from property map.
• Admin: Added black list for env variables and system properties
• Swagger: Clean up error handling for admin and meta-data reader
• HttpServer / EndpointServer: Improve info message so it does not say null for host
• Admin: Added admin port env var
• REST support now works with Map<String, Object>, and can converts all Value types to non-value types and sub-maps (Map<String, Object>)

• Improved swagger
• Added JVM stats collection
• Created auto service discovery / consul checkin for endpoint servers and http servers

• Exposed swagger through admin • Added admin endpoint to ManagedServiceBuilder • Exposed admin endpoint as __admin to make it consistent with local stats collections and health • Added support for Map<String, String> to swagger support • Added ssl support to http server and client • Fixed bug in BasicQueue when dealing with ArrayBlockingQueue • Fixed ServiceBuilder so you can pass beforeMethodCall or beforeMethodCallAfterTransform • Fixed health check NPE which was happening every hour or so • Auto registry with endpoint builder to service discovery and health implemented • EventBusCluster now uses Service Discovery instead of using Consul direct

• Added support for annotations by default like @JsonIgnore, @SerializedName, etc.
• Health Service was sending too many pings. The timer was not reset after send.

• Documented and tested removing /serivces to / or /whatever
• Switched Consul client to use HTTP and not to use connection pools
• got rid of extra call to flush which was failing for proxies from stats service. This was filling up logging for non-remote stats.
• Added utility class to implement /__health and /__stats/instance endpoints
• Improved statsd replicator. making it less chatty. fixed timing.
• Improved ServiceContext support and added ability to mark a service as down for health system auto-checkins.
