在使用git filter-branch --subdirectory-filter后，我仍然如何使用旧回购和回收git空间？ [英] After using git filter-branch --subdirectory-filter how do I still use old repo and reclaim git space?

问题描述

我使用 git filter-branch 将一个子文件夹拆分成一个新的存储库，参考 https://help.github.com/articles/splitting-a-subfolder-out-into-a-new -repository / 和 https://stackoverflow.com/a/45983384/301513

I use git filter-branch to split a subfolder out into a new repository, refer to https://help.github.com/articles/splitting-a-subfolder-out-into-a-new-repository/ and https://stackoverflow.com/a/45983384/301513

我的问题是，根据文章中的步骤，我需要创建一个新的repo和 git pull the-subdirectory-filter-result

My question is, according to the steps in the article, I need to create a new repo and git pull the-subdirectory-filter-result into the new repo. But is it possible I can still use old repo and reclaim the git space, i.e to make the old .git only has that subdirectory related metadata? If I can, I don't need to create a new repo, after all the old one does not have much use now.

我试过Paul的第5步在 https://stackoverflow.com/a/359759/301513 上回答，但它不起作用。并且 git gc 不会为这些不相关的提交回收git历史记录。

I tried the step #5 in Paul's answer at https://stackoverflow.com/a/359759/301513, but it did not work. And git gc won't reclaim the git history for those un-related commits.

推荐答案

您可以将不需要的历史记录和文件夹归档，然后将文件移动到根目录。这里从git / GitHub的历史记录中删除文件夹及其内容是rm文件夹和文件的几个选项。

You could rm the history and folders you don't want then then move the files to the root. Here Remove folder and its contents from git/GitHub's history are several options to rm folders and files.
