v0.99.3

April 14, 2020

🌟 New features

• Added RetryStrategy.onException() #2652
• Armeria clients can now send an OPTIONS * HTTP/1 request as an alternative to an HTTP/2 PING frame. #2636
  • This feature is disabled by default and you can enable it by:
    • specifying com.linecorp.armeria.defaultPingIntervalMillis system property
    • or calling ClientFactoryBuilder.pingIntervalMillis().

📈 Improvements

• DocService debug form now prettifies any JSON responses. #2635

🛠️ Bug fixes

• grpc-timeout gRPC client header is generated correctly now. #2643
• QueryParams.toQueryString() does not raise an exception anymore. #2644
• HealthCheckedEndpointGroup does not raise aConcurrentModificationException anymore. #2647
• Thrift TEXT protocol does not fail to handle a recursive union struct anymore. #2654
• MoreNamingConventions.prometheus() now appends the seconds suffix for LongTaskTimer correctly, when using legacy meter names. #2646
• Fixed a bug where DocService sends a request with a wrong HTTP method if a service specification contains duplicate methods. #2657

☢️ Breaking changes

• com.linecorp.armeria.defaultHttp2PingTimeoutMillis flag has been replaced with com.linecorp.armeria.defaultPintIntervalMillis.
• com.linecorp.armeria.defaultUseHttp2PingWhenNoActiveStreams flag has been removed without a replacement, because:
  • HTTP/2 can send PING frame regardless of whether there is an active stream or not.
  • HTTP/1 can only send OPTIONS * HTTP/1.1 when there is no active stream.
• ClientFactoryBuilder.http2PingTimeoutMillis() has been replaced with ClientFactoryBuilder.pingIntervalMillis().
• ServerBuilder.http2PingTimeoutMillis() has been replaced with ServerBuilder.pingIntervalMillis().
