重要变更介绍
新特性
1. 泛化调用：泛化 Client 支持流式调用，一个 Client 搞定流式/非流式调用场景
泛化 Client 支持流式泛化调用，适配 gRPC/TTHeader Streaming 并支持 map / json 和 protobuf 二进制泛化调用。
简要代码示例如下：
cli, err := genericclient.NewClient("actualServiceName", g)
// Ping-Pong 泛化
resp, err := cli.GenericCall(ctx, "PingPongTest", req)
// ClientStreaming 泛化
cliStream, err := cli.ClientStreaming(ctx, "ClientStreamingTest")
// ServerStreaming 泛化
srvStream, err := cli.ServerStreaming(ctx, "ServerStreamingTest", req)
// BidiStreaming 泛化
bidiStream, err := cli.BidiStreaming(ctx, "BidiStreamingTest")各场景使用细节请参考泛化调用。
功能/体验优化
1. Streaming： 观测/排错体验优化
TTHeader Streaming
- 若配置了 Tracer，创建 Stream 失败将打点上报
- 当 Server 侧发生 panic 时，将打印完整堆栈，方便排查问题
gRPC Streaming
若配置了 Tracer，创建 Stream 失败将打点上报
其他
1. 产物简化
Kitex Tool 不再生成 fastpb，只影响 protobuf 的用户。若有高性能 protobuf 编解码需求，可配置环境变量 KITEX_TOOL_USE_PRUTAL_MARSHAL=1启用 prutal。
