GRPC 1.15.0 发布,Google 高性能 RPC 框架

必威平台 www.gddgtsmy.com GRPC 1.15.0 已发布,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。?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。

该版本包含优化、改进和 bug 修复,亮点包括:

Core

  • Document SSL portability and performance considerations. 详情
  • Simplify call arena size growth. (#16396)
  • Make gRPC buildable with AIX and Solaris (no official support). (#15926)
  • PF: Check connectivity state before watching. (#16306)
  • Added system roots feature to load roots from OS trust store. (#16083)
  • Fix c-ares compilation under windows (but doesn’t yet enable windows DNS queries), and then enables address sorting on Windows. (#16163)
  • Fix re-resolution in pick first. (#16076)
  • Allow error strings in final_info to propagate to filters on call destruction. (#16104)
  • Add resolver executor . (#16010)
  • Data race fix for lockfree_event. (#16053)
  • Channelz: Expose new Core API. (#16022)

C++

  • cmake: disable assembly optimizations only when necessary. (#16415)
  • C++ sync server: Return status?RESOURCE_EXHAUSTED?if no thread quota available. (#16356)
  • Use correct target name for gflags-config.cmake. (#16343)
  • Make should generate pkg-config file for gpr as well. (#15295)
  • Restrict the number of threads in C++ sync server. (#16217)
  • Allow reset of connection backoff. (#16225)

C#

  • Add experimental support for Xamarin.Android and Xamarin.iOS, added Helloworld example for Xamarin. 详情
  • Add experimental support for Unity Android and iOS. 详情
  • Add server reflection tutorial. 详情
  • Avoid deadlock while cancelling a call. (#16440)
  • Subchannel sharing for secure channels now works as expected. (#16438)
  • Allow dot in metadata keys. (#16444)
  • Avoid shutdown crash on iOS. (#16308)
  • Add script for creating a C# package for Unity. (#16208)
  • Add Xamarin example. (#16194)
  • Cleanup and update C# examples. (#16144)
  • Grpc.Core: add support for x86 android emulator. (#16121)
  • Xamarin iOS: Add libgrpc_csharp_ext.a for iOS into Grpc.Core nuget. (#16109)
  • Xamarin support improvements . (#16099)
  • Mark native callbacks with?MonoPInvokeCallback. (#16094)
  • Xamarin.Android: add support. (#15969)

Objective-C

  • Make BoringSSL symbols private to gRPC in Obj-C so there is no conflict when linking with OpenSSL. (#16358)
  • Use environment variable to enable CFStream. (#16261)
  • Surface error_string to ObjC users. (#16271)
  • Fix?GRPCCall?refcounting issue. (#16213)

Python

  • Added support for client-side fork on Linux and Mac by setting the environment variable?GRPC_ENABLE_FORK_SUPPORT=1. Applications may fork with active RPCs, as long as no user threads are currently invoking gRPC library methods. In-progress RPCs continue in the parent process, and the child process may use gRPC by creating new channels. (#16264)
  • Improve Pypy compatibility. (#16364)
  • Segmentation fault caused by?channel.close()?when used with connectivity-state subscriptions. (#16296)
  • Add server reflection guide for Python. 详情
  • Refresh pb2 files in examples/python/multiplex. (#16253)
  • Adding python version environmental markers in the new style. (#16235)
  • Add a matching?_unwrap_grpc_arg. (#16197)
  • Add Cython functionality to directly wrap?grpc_arg. (#16192)
