v0.82.0

March 19, 2019

New features

• You can now include or exclude service methods using DocServiceFilter when building a DocService. See our documentation for more information. #1609

  ServerBuilder sb = new ServerBuilder();
  ...
  sb.serviceUnder("/docs", new DocServiceBuilder()
          // Include Thrift services and Annotated services.
          .include(DocServiceFilter.ofThrift().or(DocServiceFilter.ofAnnotated()))
          // Exclude the method whose name is "foo" in Thrift services.
          .exclude(DocServiceFilter.ofThrift().and(DocServiceFilter.ofMethodName("foo")))
          .build());

• HttpHeaderNames now forks from Guava's HttpHeaders instead of Netty's HttpHeaderNames because it has more recent HTTP headers which may be useful to service authors.

• You can use SystemInfo utility class in order to get the system information. #1656

  // Java version
  SystemInfo.javaVersion();
  
  // Hostname
  SystemInfo.hostname();
  
  // The current process ID
  SystemInfo.pid();
  
  // The current time in microseconds
  SystemInfo.currentTimeMicros();

Improvements

• Set 0.5 to the default failure rate threshold of a circuit breaker. #1657
• Various documentation updates. #1657 #1654 #1651

Bug fixes

• Strip a leading slash in an HttpFile resource path. #1661 #1650

  // Will strip the leading slash
  HttpFile.ofResource(ClassLoader.getSystemClassLoader(), "/java/lang/Object.class");

• ByteBufs are no longer leaked when you use Spring WebFlux integration. #1658 It was possible to leak a ByteBuf if a client closes a connection before reading the body of an HTTP response.

Breaking Change

• DocServicePlugin interface now has name() method and generateSpecification() method signature has changed. #1609

  // Before:
  ServiceSpecification generateSpecification(Set<ServiceConfig> serviceConfigs);
  // After:
  String name();
  ServiceSpecification generateSpecification(Set<ServiceConfig> serviceConfigs, DocServiceFilter filter);

• Some header names in HttpHeaderNames were removed, although it is very unlikely to be used by users: #1660
• Keep-Alive
• Proxy-Connection
• Content-Transfer-Encoding
