armeria-0.12.2.Final

Bug fixes

• #130 Fix NPE while recording tracing annotations

armeria-0.12.1.Final

Bug Fixes

• #127 Propagate all non-null ServerSpans (Zipkin integration)

armeria-0.12.0.Final

New features

• #122 Make EventLoop available to RemoteInvoker.invoke()
  • NB: This is a breaking change due to the signature change of RemoteInvoker.invoke(). You won't notice this at all if you did not implement RemoteInvoker by yourself to write a decorator.
• #125 Allow registering callbacks when propagating a ServiceInvocationContext
  • You can add callbacks to a ServiceInvocationContext via onEnter(Runnable) and onExit(Runnable).

armeria-0.11.0.Final

New features

• #114 Distributed tracing via Zipkin/Brave

This release introduces distributed tracing capability to Armeria clients and servers using Brave, a distributed tracing library compatible with Zipkin. This enables us to watch timing data among the whole Armeria RPC chain.

Decorating a client

// Create a brave instance with service name, span collector, and sampling rate.
Brave brave = new Brave.Builder("MyClientMain")
        .spanCollector(new ScribeSpanCollector("127.0.0.1", 9410))
        .traceSampler(Sampler.create(0.01f))
        .build();

MyService.Iface client =
        new ClientBuilder("tbinary+http://127.0.0.1:8080/thrift/myService")
                .decorator(HttpTracingClient.newDecorator(brave))
                .build(MyService.Iface.class);

Decorating a server

// Create a brave instance with service name, span collector, and sampling rate.
Brave brave = new Brave.Builder("MyServiceMain")
        .spanCollector(new ScribeSpanCollector("127.0.0.1", 9410))
        .traceSampler(Sampler.create(0.01f))
        .build();

ServerBuilder builder = new ServerBuilder();
builder.port(8080, SessionProtocol.HTTP);
builder.serviceAt("/thrift/myservice",
                  ThriftService.of(new MyServiceHandler(brave))
                               .decorate(HttpTracingService.newDecorator(brave));

Bug fixes

• #118 Default maxFrameLength differs between client and server side.
• #119 Unexpected exceptions are not logged properly.

armeria-0.10.0.Final

New features

• #110 Provide a way to create a TomcatService from an existing Tomcat Connector

  • Useful when using an embedded Tomcat already with other library such as Spring Boot:

  ServerBuilder sb = new ServerBuilder();
  sb.serviceUnder("/tomcat", TomcatService.forConnector("example.com", springBootConnector));

• #115 DropWizard Metrics support

  • Use MetricCollectingClient and MetricCollectingService to collect the metrics of your clients and services:

  ServerBuilder sb = new ServerBuilder();
  sb.serviceAt(
      "/thrift/foo", ThriftService.of(...).decorate(
          MetricCollectingService.newDropwizardDecorator("fooService", metricRegistry));
  
  ClientBuilder cb = new ClientBuilder(...);
  cb.decorator(MetricCollectingClient.newDropwizardDecorator("barService", metricRegistry));

Improvements

• #117 Upgrade Netty to 4.1.0.CR3

armeria-0.9.0.Final

New features

• #96 Add more configuration properties to TomcatService
• #97 Add a way to create a derived client
  • You can create a new client with different ClientOptions more efficiently using Clients.newDerivedClient().
• #107 More efficient and correct H1C-to-H2C upgrade
  • SessionProtocolNegotiationCache now keeps the recent HTTP/2 upgrade failures so that Armeria does not send an upgrade request to the hosts known to be incapable of HTTP/2. This should reduce the number of HEAD / HTTP/1.1 upgrade requests in your H1C connections.

Improvements

• #102 Upgrade to Netty 4.1.0.CR1
• #105 Reduce the unnecessarily noisy/long exceptions

Bug fixes

• #99 Check all interfaces, including ancestor interfaces, when analyzing Thrift handler
• #100 Send the correct 'Host' header when upgrading

Documentation

• #108 Missing SLF4J version in example pom.xml
• #109 Update the project setup guide / Update dependencies

armeria-0.8.0.Final

New features

• #93 Revamp the client-side decorator API
  • It is now as convenient as for the server side to decorate a client.
  • See ClientBuilder.decorator() for more information.
• #84 Add Server.nextEventLoop() so that a user can get one of the available Netty EventLoops.

Bug fixes

• #81 #82 Fix missing remote/local addresses in TomcatService
• #94 Fix an intermittent problem with CachedEntry in HttpFileService

armeria-0.7.0.Final

• #77 More robust resolution/rejection of an invocation promise
• #78 Use jetty-alpn-agent to simplify pom.xml
• #79 Add methods to ServiceInvocationContext for propagating context into callbacks

armeria-0.6.4.Final

• #73 Redirect from /path to /path/
• #74 Fix missing query string conversion in TomcatService
• #75 Pass through non-200 HTTP responses for SimpleHttpClient
• #76 Fix wrong call depth in TomcatService.forCurrentClassPath()
