背景:
在使用Oracle VM VirtualBox,进行Linux开发时,随着使用内存越来越少,空间已不足拉取整个代码库。
Ubuntu1604内存够,Ubuntu18.04内存不够。
思路:
第一步:从问题本身出发,先能满足编译需要。
方法1,手动从Ubuntu16.04上拉取最新代码,删掉不需要的文件,仅保留Ubuntu18.04需要,然后一次scp
方法2,从Ubuntu16.04上拉取最新代码,在Ubuntu18.04,多次scp所需文件
第二步:考虑自动化脚本。
方法1:从Ubuntu16.04上拉取最新代码,Ubuntu18.04上编写脚本一次执行,传输所需文件
方法2:打个疑问"git 能不能实现文件或文件夹的拉取,而且只拉取最新的?" 查阅资料,整理解决方案并验证
方法:
建立一个空的git 本地仓库:
$ git init new.project && cd new.project
在本地仓库里面启用sparse-checkout:
$ git config core.sparseCheckout true
设定你要checkout 哪些文件夹(如/xxx/*表示xxx文件夹下所有文件)(也可以用vim直接打开 .git/info/sparse-checkout写入)
$ echo '/xxx/*' >> .git/info/sparse-checkout
设定remote (要从哪里clone/pull?):
$ git remote add origin git://github.com/xxx/xxx.git
然后就可以开始pull 了(这边可以加上后面说的shallow pull,加上--depth=n
$ git pull origin master
整理:
命令行方式
git init project && cd project
git config core.sparseCheckout true
git remote add origin ssh://neal.shen@XXX.XXX.XXX.XXX:XXXXXX/SDK/SDK.git
echo '/complieLinux.sh' >> .git/info/sparse-checkout
echo '/sources/include/*' >> .git/info/sparse-checkout
echo '/sources/config/*' >> .git/info/sparse-checkout
echo '/sources/json/*' >> .git/info/sparse-checkout
echo '/sources/log/*' >> .git/info/sparse-checkout
echo '/sources/sensor/*' >> .git/info/sparse-checkout
echo '/sources/platforms/*' >> .git/info/sparse-checkout
echo '/sources/src/*' >> .git/info/sparse-checkout
echo '/sources/3rdparty/libjpeg-turbo-2.0.2/*' >> .git/info/sparse-checkout
echo '/sources/3rdparty/opencv/bulid/include_3.4.16/*' >> .git/info/sparse-checkout
echo '/sources/3rdparty/opencv/bulid/x64/ubuntu18.04/lib_3416/*' >> .git/info/sparse-checkout
echo '/sources/3rdparty/algorithm/PC_ImgPreProc/ImgPreProcess/*' >> .git/info/sparse-checkout
echo '/sources/3rdparty/algorithm/imgpreproc/include/*' >> .git/info/sparse-checkout
录取全部记录
git pull origin v3
只拉取最近一次的变更,忽略以前的变更记录,在拉取时可以加参数depth
git pull --depth=1 origin v3
sparse-checkout文件内容:
/complieLinux.sh
/sources/include/*
/sources/config/*
/sources/json/*
/sources/sensor/*
/sources/platforms/*
/sources/3rdparty/libjpeg-turbo-2.0.2/*
/sources/3rdparty/opencv/bulid/include_3.4.16/*
/sources/3rdparty/opencv/bulid/x64/ubuntu18.04/lib_3416/*
/sources/3rdparty/algorithm/PC_ImgPreProc/ImgPreProcess/*
/sources/3rdparty/algorithm/imgpreproc/include/*

gitpull()
print ('end')
补充知识点:
python os.system("cd 目录") 不起效
使用os提供的os.chdir('目录')
总结:
Ubuntu18.04已验证OK
