0.82.0 release notes

19th March 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
