即使文件未登台，git也会占用空间 [英] git use up space even when file is unstaged

问题描述

我想使用git-lfs将较大的二进制文件添加到我的git存储库中，但是失败了:

I wanted to use git-lfs to add a large binary into my git repository but that failed:

$ git add large-file.tar.xz

所以我取消了文件的存储

So I unstage the file

$ git checkout -- large-file.tar.xz
$ git status
On branch lfs
nothing to commit, working tree clean

但是git仍然会用完大文件的磁盘空间.

But the git still use up the disk space for the large file.

$ du -sh .git
101M    .git

回收空间

我尝试使用 BFG回购清洁器除去斑点，但没有任何操作被发现. (是的，BFG只扫描现有的提交，但是我很绝望)

Reclaiming the space

I tried using the BFG repo cleaner to remove the blob, but nothing is found. (Yes, BFG only scan for existing commits, but I was desperate)

$ bfg --strip-blobs-bigger-than 10M .

Using repo :path/to/project

Scanning packfile for large blobs: 725
Scanning packfile for large blobs completed in 31 ms.
Warning : no large blobs matching criteria found in packfiles - does the repo need to be packed?

git gc不能正常工作

$git reflog expire --expire=now --all && git gc --prune=now --aggressive
$ du -sh .git
101M    .git

推荐答案

不要忘记删除任何bfg或filter-branch操作留下的原始对象.

Don't forget to delete the original objects left as a backup by any bfg or filter-branch operation.

rm -Rf .git/refs/original

然后您可以修剪其余部分:

Then you can prune the rest:

git reflog expire --expire=now --all
git gc --prune=now
git gc --aggressive --prune=now
git repack -Ad      # kills in-pack garbage
git prune           # kills loose garbage
