新闻 gRPC 1.10.0 正式发布，Google 高性能 RPC 框架 下载

gRPC 1.10.0 已正式发布，该版本包含了大量改进和 bug 修复，具体如下：

Core

• 
  To provide a cleaner install with fewer public headers, several features of core have been removed from the surface or GPR API as they were not used in any wrapped language (except C++) or in external applications, such as:
  a. grpc_alarm (removed; the C++ grpc::Alarm now directly invokes core subsurface functions)
  b. gpr_join_host_port, gpr_cmdline, gpr_subprocess (moved to test/core/util)
  c. gpr_tls, gpr_avl (internalized)
  d. gpr_thd (internalized)
  
  
  • 
    Except gpr_thd_id and gpr_thd_currentid, which remain public
    
• 
  As a result of these changes, core is now at version 6.0.0
  
  
• 
  Fix memory leaks in max_age_filter (#14501) and http_proxy (#14137)
  
  
• 
  Changed resolver and LB policy APIs to C++
  
  
• 
  Added re-resolution into grpclb policy (#14438).
  
  
• 
  Extracted per LB-call data from grpclb policy (#13911)
  
  
• 
  Fixed C-core to immediately take ownership of slices when a send_message op is started
  
  
• 
  Fix a race condition causing freeze at shutdown with epollex polling strategy (#14177)
  
  
• 
  Improvements in CMake: find_package (#14353)
  
  
• 
  Portability fixes (#14136, #14198)
  
  
• 
  Test infrastructure cleanup (#14117)
  
  
• 
  Update BoringSSL submodule (#13948)
  
  
• 
  Make RR re-resolve when any of its subchannels fail (#14170)
  
  
• 
  DNS resolver caches results, allowing it to be hit arbitrarily often. Resolution frequency is controlled via channel arg GRPC_ARG_DNS_MIN_TIME_BETWEEN_RESOLUTIONS_MS. (#14228)

gRPC 是一个高性能、开源、通用的 RPC 框架，面向移动和 HTTP/2 设计，是由谷歌发布的首款基于 Protocol Buffers 的 RPC 框架。目前提供 C、Java 和 Go 语言版本，分别是：grpc, grpc-java, grpc-go. 其中 C 版本支持 C, C++, Node.js, Python, Ruby, Objective-C, PHP 和 C#。

gRPC 基于 HTTP/2 标准设计，带来诸如双向流、流控、头部压缩、单 TCP 连接上的多复用请求等特性。这些特性使得其在移动设备上表现更好，更省电且节省空间占用。



服务接口定义示例：

message HelloRequest {
string greeting = 1;
}

message HelloResponse {
string reply = 1;
}

service HelloService {
rpc SayHello(HelloRequest) returns (HelloResponse);
}
