清理git存储库BFG Repo-Cleaner ---推送后repo大小仍然很大

Question

我正在尝试用BFG repo清理器清理我的git存储库。所以我做了： git clone --mirror https://github.com/FourierFlows/FourierFlows.jl.git 使用BFG，例如， java -jar bfg-1.13.0.jar --delete-files 'twodturb*.png' FourierFlows.jl.git 然后 cd FourierFlows.jl.git git reflog expire --expire=now --all && git gc --prune=now --aggressive

存储库现在要小得多（1.9MB而不是880MB）。但是当我再次推回并再次尝试git clone --mirror时，我仍然得到了我开始使用的存储库。

但是，如果我将存储库推送到空的git repo，然后从那里克隆它，那确实很小。

任何想法为什么会这样？显然我不知道git是否已经放弃了存储库中的文件...

Answer 1

这是清理GitHub repos的常见问题。问题的关键是：

! [remote rejected] refs/pull/10/head -> refs/pull/10/head (deny updating a hidden ref)

因此，在GitHub遥控器中没有清理已清理的Pull Requests中的所有历史记录。

这在how to remove sensitive data的GitHub文档（强调我的）中进行了简要讨论：

  

本文将告诉您如何使用GitHub存储库中任何分支或标记无法访问敏感数据的提交。但是，重要的是要注意，这些提交仍然可以在存储库的任何克隆或分支中访问，直接通过GitHub上的缓存视图中的SHA-1哈希，以及引用它们的任何拉取请求 。您无法对存储库的现有克隆或分支执行任何操作，但您可以通过联系GitHub支持永久删除所有存储库的缓存视图并在GitHub上提取请求。

因此，如果你想要你的Pull请求，以及他们引用的所有提交/历史记录，那么你在GitHub上的总回购大小可以缩小（除了已经缩小的默认克隆的大小），你需要联系GitHub支持。
