Question

我设置了.gitattributes来制作一些二进制文件LFS。没意识到我已经有了一些git钩子，所以我没有git lfs钩子。我进行了一次推送，现在在上游仓库中，所有二进制文件只是空指针，实际上没有文件上传。

所以我现在安装了正确的git lfs挂钩，但是现在我该怎么做才能实际上传文件？ git lfs push表示一切都是最新的，尽管不是最新的。

我尝试了git rm --cached file.bin && git add file.bin，但是却什么也没做（状态仍然是最新的）。

Answer 1

我知道了。只需执行git lfs push <remote> <branch> --all即可推送文件。

Answer 2

我想补充一点。我经常发现，对于非常大的提交（例如，让我们拥有20GB的文件）如果网络连接完全中断，则git lfs将部分通过推送失败。推送20GB的文件需要很长时间，因此很容易发生。

我编写了这些脚本（mac和Windows）来分别推送每个文件，因此每次上传都是原子的。如果确实失败，则至少可以从您所在的位置重新启动，并且通过原子推送，在单个推送上失败的可能性较小。

Windows（在Git bash上运行）


#!/bin/sh

# This script is for adding files to Git LFS and then pushing them to a repo.
# It assumes you have already initalized git lfs. 
#
# Why do you need this script?
# If you need to push a loooooooot of dependencies to Git LFS. 
# If you try to push all your files at once in a single commit, any sort of 
# interruption in network connectivity could cause the push to fail and then 
# you will have to start all over again. This happened to me several times as I # tried to push 24 GB of files via git lfs to a repository. I wrote this script
# to commit and then push each file individually so I could get past that hurdle
# and move on to other things. 

# Cons: this makes the commit history rather long, but after you do it once, 
# it should be smooth sailing from there. I've never had this con cause me any
# trouble.

如何从失败的git lfs push中恢复？
