git - BFG Repo Cleaner 未按预期工作

Question

我正在尝试减小较大存储库(~3.4 G)的大小，而 bfg-repo-cleaner 似乎是减小其大小的完美工具。

我按照文档中的描述运行了该工具，但只看到存储库的大小略有减少。特别令人惊讶的是，该工具已删除的一些(但不是全部)博客 (deleted-files.txt) 仍然在存储库中。我真的不想开始搞乱 git filter-branch，所以任何帮助将不胜感激。

我特意使用激进的 --no-blob-protection 选项来最大化效果。我在截断的输出中包含了我运行的命令。

Protected commits
-----------------

You're not protecting any commits, which means the BFG will modify the contents of even *current* commits.

This isn't recommended - ideally, if your current commits are dirty, you should fix up your working copy and commit that, check that your build still works, and only then run the BFG to clean up your history.

我已经解决了这个问题。我们有很多旧 Twig 仍然指向有大 Blob 的树。删除这些并重新运行 bfg 使我减少了数 GB。

我原以为 --no-blob-protection 标志会解决这个问题。
