讓gRPC源碼下得飛起

一、遇到的問題

按照github上的說明進行操作

grpc/BUILDING.md at master · grpc/grpc

Unix
 $ git clone -b v1.28.0-pre3 https://github.com/grpc/grpc
 $ cd grpc
 $ git submodule update --init

克隆最新release版本v1.28.0-pre3，但是克隆速度巨慢。

二、解決辦法

通過碼雲導入github地址之後克隆速度顯著提升。

我已經將https://github.com/grpc/grpc導入我的碼雲倉庫，可以直接克隆。

git clone https://gitee.com/chenwr2020/grpc.git 
git checkout -b grpc_v1.28.0-pre3 v1.28.0-pre3

克隆完畢之後再切換release版本tag分支，具體可以根據實際需求來選擇分支。

在grpc目錄下打開.gitmodules，默認爲：

[submodule "third_party/zlib"]
    path = third_party/zlib
    url = https://github.com/madler/zlib
    # When using CMake to build, the zlib submodule ends up with a
    # generated file that makes Git consider the submodule dirty. This
    # state can be ignored for day-to-day development on gRPC.
    ignore = dirty
[submodule "third_party/protobuf"]
    path = third_party/protobuf
    url = https://github.com/google/protobuf.git
    branch = 3.0.x

    url = https://github.com/libuv/libuv.git

git submodule update --init 會克隆一些子模塊倉庫。自動安裝這些第三方模塊倉庫還是很慢，我已經將第三方模塊的倉庫都導入我的碼雲倉庫。

速度提升不止一個檔次。
