之前对于node-red代码的备份都是复制~/.node-red/flows_xxx.json文件并保存n个版本，很烦，即使使用Beyond Compare这种对比软件去对比未美化格式的json文件查看更改内容也是一团糟，
搜索时发现可以通过更改~/.node-red/settings.js中的设置使flows_xxx.json文件保存时就美化格式。
在视图删除某个远程分支的时候显示：remote ref does not exist
解决方案是首先清除远程分支的本地缓存：git fetch -p origin
可以看到，我们要删除的远程分支其实已经删除了。
Gitlab 服务器刚进行完数据恢复
所有的旧仓库无法进行git push操作
错误提示error: unpack failed: unable to create temporary object directory
但是新增的仓库，可以正常进行git push
升级时会清空环境设置
这一点群晖有点。。。
基本上只要把
GITLAB_HTTPS=true
SSL_SELF_SIGNED=true
给加回来
再把端口号从80改为443即可
今天打算把 Gitlab 从 11 版本升级到 12 版本，按默认的步骤试了很多次都没成功。
