5.7. Git Large File Storage

https://git-lfs.github.com/

Git Large File Storage | Git Large File Storage (LFS) replaces large files such as audio samples, videos, datasets, and graphics with text pointers inside Git, while storing the file contents on a remote server like GitHub.com or GitHub Enterprise.

	
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew install git-lfs	
	
	

5.7.1. 安装 LFS 支持

		
git lfs install
git lfs track "*.psd"
git add .gitattributes

git add file.psd
git commit -m "Add design file"
git push origin master	
		
		

5.7.2. LFS lock

文件锁的用途是用户可以对一个文件进行加锁,阻止其他用户同一时间对该文件进行修改操作。因为在GIT仓库中同时编辑一个文件,会发生冲突,然而解决二进制大文件的冲突,合并操作极其困难。

		
neo@MacBook-Pro ~/workspace/java-project % git lfs lock test.psd  
Locked test.psd

neo@MacBook-Pro ~/workspace/java-project % git lfs locks
test.psd	bg7nyt	ID:55777		
		
		

如果Push被锁的文件,提示 Remote "origin" does not support the LFS locking API

		
neo@MacBook-Pro /tmp/java % git commit -a -m 'aaa'
[master b832eb3] aaa
 1 file changed, 2 insertions(+), 2 deletions(-)
neo@MacBook-Pro /tmp/java % git push
Remote "origin" does not support the LFS locking API. Consider disabling it with:
  $ git config 'lfs.https://github.com/bg7nyt/java.git/info/lfs.locksverify' false
Post https://github.com/bg7nyt/java.git/info/lfs/locks/verify: EOF
error: failed to push some refs to 'https://github.com/bg7nyt/java.git'		
		
		

解锁后Push成功

		
neo@MacBook-Pro ~/workspace/java-project % git lfs unlock test.psd    
Unlocked test.psd

neo@MacBook-Pro /tmp/java % git push
