v0.81.0

March 8, 2019

New features

• A user now can generate cache-control header value programmatically. #1615

  HttpHeaders headers = HttpHeaders.of();
  HttpFileBuilder fileBuilder = HttpFileBuilder.of(...);
  HttpFileServiceBuilder fileServiceBuilder = HttpFileServiceBuilder.forFileSystem(...);
  
  // Before:
  headers.set(HttpHeaderNames.CACHE_CONTROL, "no-cache, no-store, must-revalidate"));
  fileBuilder.setHeader(HttpHeaderNames.CACHE_CONTROL,
                        "max-age=86400, no-cache, must-revalidate");
  fileServiceBuilder.setHeader(HttpHeaderNames.CACHE_CONTROL, "public, max-age=3600");
  
  // After:
  headers.setObject(HttpHeaderNames.CACHE_CONTROL, ServerCacheControl.DISABLED);
  fileBuilder.cacheControl(new ServerCacheControlBuilder()
                                   .maxAgeSeconds(86400)
                                   .noCache()
                                   .mustRevalidate()
                                   .build());
  fileServiceBuilder.cacheControl(new ServerCacheControlBuilder()
                                          .cachePublic()
                                          .maxAgeSeconds(3600)
                                          .build());

• Armeria supports gRPC Server Reflection. #1623

  ServerBuilder sb = new ServerBuilder();
  sb.service(new GrpcServiceBuilder().addService(new MyHelloService())
                                     .addService(ProtoReflectionService.newInstance())
                                     .build());

• Added StreamMessage.drailAll(...) to simply collect all the elements from the StreamMessage. #1620

  HttpResponse res = HttpResponse.of(HttpHeaders.of(HttpStatus.OK)
                                                .contentType(PLAIN_TEXT_UTF_8),
                                     HttpData.ofUtf8("bob"),
                                     HttpHeaders.of(CONTENT_MD5, "hash"));
  // Simply collect all the elements.
  List<HttpObject> drained = res.drainAll().join();
  assertThat(drained).containsExactly(
          HttpHeaders.of(HttpStatus.OK)
                     .contentType(PLAIN_TEXT_UTF_8),
          HttpData.of(StandardCharsets.UTF_8, "bob"),
          HttpHeaders.of(CONTENT_MD5, "hash"));

• A user is able to see the HTTP trailers in a RequestLog. #1614

Improvements

• Added more logging to SamlService to inform the reasons of the failure. #1629
• Various documentation updates. #1604, #1607, #1610, #1611, #1613, #1618, #1626, #1627, #1628

Bug fixes

• Fixed a bug where HTTP trailers is added to message headers. #1620
• Fixed a bug where the TLS handshake exception pollutes the log message. #1612
• Fixed a bug where Server-Sent Events messages miss the end-of-line character. #1610
• Fixed an API design flaw where a user cannot specify more than one decorator when adding a ServiceWithPathMappings. #1627
• Fixed a bug where contentPreview is not working correctly. #1624
• Fixed a bug where a StackOverFlowError is raised while finding annotations in AnnotationUtil. #1635
• Fixed a bug where the Armeria actuator sends the response with the incorrect media type. #1641

Breaking Change

• The HttpHeaders is added to get() in HttpVfs as a parameter. #1615
  • A user can easily add the HttpHeaders when building an HttpFile.
