git  clone出现 "fatal: The remote end hung up unexpectedly" 
设置
 git config --global http.postBuffer 104857600000
后git clone报错
fatal: Out of memory, malloc failed (tried to allocate 1778384896 bytes)
 又把postBuffer改了回去 git config --global http.postBuffer 10485760000
采用深度为1来控制
git clone xxx.git xxxxx --depth 1
