在filter-branch --tree-filter之后从git repo删除refs / original / heads / master？

问题描述

我有同样的问题在这里问：

我在这里跟随了这个答案：

现在， gitk --all 显示了两个历史记录：一个在当前 master 结尾，另一个名为 original / refs / heads / master 。

我不知道第二个历史是什么，或者如何从回购中删除它。我不需要两个历史记录。

如何摆脱它？

要复制自己：

  mkdir -p project-root / path / to / module 
 cd project-root / path / to / module 
 mkdir dir1 dir2 dir3 
 for dir in *;请触摸$ dir / source-file- $ dir.py;完成
 git init 
 git add。 
 git commit -m'初始提交'
  

现在我们有原始海报的问题了。让我们将git repo的根移到project-root，使用上面的链接：过滤器'mkdir -p path / to / module; git mv dir1 dir2 dir3 path / to / module'HEAD
rm -rf path
cd ../../../＃现在PWD是项目根目录
mv path / to /模块/ .git。
git reset --hard

现在，看看我目前的问题：

  gitk --all& 
 git show-ref 
  

如何摆脱 refs / original / heads / master 和所有关联的历史记录？

解决方案

refs / original / * 是否存在备份，以防你搞乱你的过滤分支。相信我，这真的是个好主意。

一旦你检查了结果，并且你非常有把握地确信你拥有了你想要，你可以删除备份的ref：

  git update-ref -d refs / original / refs / heads / master 
  

或者如果你对很多参考文献都这样做了，并且想要全部清除：

  git for-each-ref --format =％（refname）refs / original / | xargs -n 1 git update-ref -d 
  

（这是直接从filter-branch手册页获取的。 ）这不适用于你，但对于其他人可能会发现这一点：如果你做一个过滤器分支删除内容采取增加大量的磁盘空间，你可能还想运行 git reflog expire --expire = now --all 和 git gc --prune = now 过期你的reflog并删除现在未使用的对象。 （警告：完全不可逆转，在做之前要非常确定。）

I had the same question as asked here: New git repository in root directory to subsume an exist 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

Now, gitk --all shows two histories: one culminating in the current master, and one named 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.

How do I get rid of it?

To reproduce yourself:

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:

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:

gitk --all &
git show-ref

How do I get rid of refs/original/heads/master and all associated history?

解决方案

refs/original/* is there as a backup, in case you mess up your filter-branch. Believe me, it's a really good idea.

Once you've inspected the results, and you're very confident that you have what you want, you can remove the backed up 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:

git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

(That's taken directly from the filter-branch manpage.)

This doesn't apply to you, but to others who may find this: If you do a filter-branch which removes content taking up significant disk space, you might also want to run git reflog expire --expire=now --all and git gc --prune=now to expire your reflogs and delete the now-unused objects. (Warning: completely, totally irreversible. Be very sure before you do it.)
