Remove refs/original/heads/master from git repo after filter-branch --tree-filter?
提问by goofeedude
I had the same question as asked here: New git repository in root directory to subsume an exist repository in a sub-directory
我在这里问了同样的问题：New git repository in root directory to subsume an existing repository in a sub-directory
I followed this answer here: New git repository in root directory to subsume an exist repository in a sub-directory
我在这里遵循了这个答案：New git repository in root directory to subsume an existing repository in a sub-directory
Now, gitk --allshows two histories: one culminating in the current master, and one named original/refs/heads/master.
现在，gitk --all显示了两种历史：一种以当前master为高潮，另一种名为original/refs/heads/master。
I don't know what this second history is, or how to remove it from the repo. I don't need two histories in my repository.
我不知道这第二个历史是什么，也不知道如何从 repo 中删除它。我的存储库中不需要两个历史记录。
How do I get rid of it?
我该如何摆脱它？
To reproduce yourself:
要重现自己：
mkdir -p project-root/path/to/module
cd project-root/path/to/module
mkdir dir1 dir2 dir3
for dir in * ; do touch $dir/source-file-$dir.py ; done
git init
git add .
git commit -m 'Initial commit'
Now we have the original poster's problem. Let's move the root of the git repo to project-root using the answer linked above:
现在我们有了原始海报的问题。让我们使用上面链接的答案将 git repo 的根目录移动到 project-root ：
git filter-branch --tree-filter 'mkdir -p path/to/module ; git mv dir1 dir2 dir3 path/to/module' HEAD
rm -rf path
cd ../../../ # Now PWD is project-root
mv path/to/module/.git .
git reset --hard
Now, see my current problem:
现在，看看我目前的问题：
gitk --all &
git show-ref
How do I get rid of refs/original/heads/masterand all associated history?
我如何摆脱refs/original/heads/master和所有相关的历史？

refs/original/*is there as a backup, in case you mess up your filter-branch. Believe me, it's a reallygood idea.
refs/original/*是否有备份，以防您弄乱过滤器分支。相信我，这真是个好主意。
Once you've inspected the results, and you're very confident that you have what you want, you can remove the backed up ref:
一旦您检查了结果，并且您非常有信心拥有您想要的东西，您就可以删除备份的 ref：
git update-ref -d refs/original/refs/heads/master
or if you did this to many refs, and you want to wipe it all out:
或者，如果您对许多裁判这样做了，并且想将其全部清除：
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d
(That's taken directly from the filter-branch manpage.)
（这直接取自过滤器分支联机帮助页。）
This doesn't apply to you, but to others who may find this: If you do a filter-branch which removescontent taking up significant disk space, you might also want to run git reflog expire --expire=now --alland git gc --prune=nowto expire your reflogs and delete the now-unused objects. (Warning: completely, totally irreversible. Be very sure before you do it.)
这不适用于您，但适用于可能会发现此问题的其他人：如果您执行过滤器分支删除占用大量磁盘空间的内容，您可能还希望运行git reflog expire --expire=now --all并使git gc --prune=now您的引用日志过期并删除现在未使用的对象. （警告：完全，完全不可逆。在你做之前要非常确定。）

And if you're in Windows PowerShell:
如果您使用的是 Windows PowerShell：
git for-each-ref --format="%(refname)" refs/original/ | foreach-object -process { git update-ref -d $_ }

filter-branchkeeps backups so repository need to clean up reflogs and garbage collect. Make sure that have no need in this backups before deletion:
filter-branch保留备份，因此存储库需要清理引用日志和垃圾收集。确保在删除之前不需要此备份：
rm -Rf .git/refs/original
git gc --aggressive --prune=now
