armeria-0.70.0

New features

• Added RequestContextCurrentTraceContext.newBuilder() which allows a user to customize the Zipkin context, such as decorating a trace scope #1328

• Armeria now provides Spring configuration metadata for better IDE integration. #1340

  

• Added a new utility class StartStopSupport which simplifies the implementation of asynchronous start-stop style life cycle #1344

  public class MyService implements AutoCloseable {
      private final StartStopSupport<Void, MyServiceListener> startStop = new StartStopSupport<>(ForkJoinPool.commonPool()) {
          @Override
          protected CompletableFuture<Void> doStart() { /* .. Implement startup .. */ }
          @Override
          protected CompletableFuture<Void> doStop() { /* .. Implement shutdown .. */ }
          @Override
          protected void notifyStarting(MyServiceListener listener) {
              listener.myServiceStarted(this);
          }
          ...
      };
  
      public CompletableFuture<Void> start() { return startStop.start(true /* fail if started */); }
      public CompletableFuture<Void> stop() { return startStop.stop(); }
      public void addListener(MyServiceListener listener) { startStop.addListener(listener); }
  
      @Override
      public void close() { startStop.close(); }
  }
  
  MyService myService = new MyService();
  CompletableFuture<Void> startFuture = myService.start();
  CompletableFuture<Void> stopFuture = myService.stop();

Bug fixes

• The level of the log message about missing hostname command should be lowered from WARN to DEBUG, because some distributions do not have hostname command. #1333 #1348
• RequestContext is not pushed for some gRPC callbacks such as onReady(). #1338

Deprecations

• RequestContextCurrentTraceContext.INSTANCE has been deprecated in favor of RequestContextCurrentTraceContext.DEFAULT. #1328
