Git历史既重写又不变吗？

Question

所以我一夜之间让Git重写了我所有分支的历史，当我查看结果时，我看到了：

​

      E:\zeus>git filter-branch -f --tree-filter "rm -rf ZeusSRC_Hardware_RPi_image_Raspberry Pi_außen_20.05.2019.zip" --prune-empty -- --all

所以基本上，git向我展示了它既改变了东西，又没有改变东西，不知何故？

到目前为止，我可以看到，本地部分完全改变了，而远程部分只有部分改变。存储库的大小保持不变(8G)，但应该减少到4G。

所以有两件事:首先，有人知道造成这种混合结果的原因是什么吗？我在Win10上运行，没有管理员权限，来自git CMD。第二，这样的结果是否“有问题”？我的意思是，有些东西变了，有些还没变。我是否应该删除然后再次克隆存储库，以便为下一次尝试提供干净的基础？

Answer 1

1. 如果引用未更改，则自第一次提交以来，该引用的历史记录中从未包含已删除的文件和目录。
2. 大小未变小，因为相关对象仍在存储库中。它们将在那里存在很长一段时间，直到有一天它们被垃圾收集。如果它们立即被清除，这意味着您不能回滚refs，以防您后悔或错误地运行git filter-branch。
