iDste:创建android本地版本库

android系统的源代码是通过git和repo来进行组织和管理的，官方提供通过从官网上获取源码的repo工具。

由于国内网路环境的原因，从国内获取android源码库变得较为困难。为了方便后续使用和开发，需要在本地建立一个官网的版本镜像，本文主要是介绍在本地建立android的版本库镜像和从本地版本库获取源代码的方法。

建立本地版本镜像

1. 在ubuntu系统上安装git-core

apt-get install git-core
apt-get install git-daemon-run

2. 创建本地源码库的存放路径

mkdir -p /pub/gittree

3. 修改配置：

$sudo gedit /etc/sv/git-daemon/run
将该文件中的
/usr/lib/git-core/git-daemon –verbose –base-path=/var/cache /var/cache/git
改为
/usr/lib/git-core/git-daemon –verbose –export-all –base-path=/pub/gittree /pub/gittree

4. 重启git服务

sv stop git-daemon
sv stop git-daemon

5. 确认服务已经正确运行

ps -ef | grep git
输出

root3378 3333 0 10:29 ?00:00:00 runsv git-daemon
gitlog3379 3378 0 10:29 ?00:00:00 svlogd -tt /var/log/git-daemon
1073391 3378 0 10:36 ?00:00:00 /usr/lib/git-core/git-daemon –verbose –reuseaddr –export-all –base-path=/pub/gittree /pub/gittree

6. 将源码库从官网上同步到本地

curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

注：
由于防火墙的作用， 国内无法直接访问这个地址， 这里必须要通过国外的代理服务器来完成\\。 我们是在国外购买了一个云主机，然后自行安装代理服务器完成的。

7. 初始化和同步源码库

cd /pub/gittree
~/bin/repo init -u https://android.googlesource.com/platform/manifest -mirror
~/bin/repo sync

一共近30G的内容， 时间较长，请耐心等待。

8. 添加4.4.1的分支的工程同步完成后， 默认是将最新版本库同步到了本地。在做imx上的android系统开发时， 系统源码需要 android-4.4.2_r1分支。 在这个分支上，有一些老版本的工程， 默认在做镜像时不会被同步到本地， 因此需要手动添加:

在/pub/gittree.repo/manifest.xml中添加如下内容：

再次执行：
~/bin/repo sync

从本地库中checkout源码

1. 创建本地的开发目录

$mkdir ~/android_branck

2. 获取repo工具

git clone git://192.168.1.125/git-repo.git
注：
192.168.1.125 为本地源码镜像库的ip地址

3. 修改repo的源地址

vi git-repo/repo
将 REPO_URL = https://gerrit.googlesource.com/git-repo
修改为 REPO_URL = git://192.168.1.125/git-repo

4. 配置git的用户信息

git config –global user.email “zhanhl@idste.cn”
git config –global user.name “zhanhl”

5. 初始化和checkout源代码

./git-repo/repo init -u git:192.168.1.125/platform/manifest -b android-4.4.2_r1
./git-repo/repo sync
