如何在filter-branch --subdirectory-filter之后从我的repo中删除不需要的对象 [英] how can I remove the unwanted objects from my repo after filter-branch --subdirectory-filter

问题描述

我正在使用

I'm using

git filter-branch --subdirectory-filter dir/name -- --all

构建一个只包含与该目录/名称相关的历史记录的仓库。在我做这个过滤器之前，我把原始的repo（这是非常大的）克隆到tmp目录中。在过滤分支之后，回购看起来就像我想要的那样，但有一个例外：它似乎仍包含原始回购的所有对象，即使它们没有显示在git log中。

to build a repo that only has history relating to that dir/name. Before I do the filter, I clone the original repo (which is very much bigger) into a tmp dir. After the filter-branch, the repo looks just how I want it, with one exception: It seems to still contain all the objects from the original repo even though they're not shown in "git log."

如何完全删除所有这些不需要的对象？

How can I remove all those unwanted objects completely?

我试过这样的事情：

git reflog expire --expire=now --all
git gc --aggressive --prune=now

我很清楚，我不知道他们为什么仍然存在，或者意味着要删除它们，但我确实希望。有些可能与我有关的信息是我曾经在我的源代码仓库上做过一次git repack -a，并且似乎将该packfile复制到新的仓库中。似乎我应该仍然可以做我想做的事情。

It's clear to me that I don't know why they're still there or what it means to remove them, but I'd sure like to. A bit of possibly related information working against me is that I had done a git repack -a on my source repo a while back and it seems to copy that packfile over to the new repo. Seems like I should still be able to do what I want though.

推荐答案

filter-branch还将备份参数保存在.git / refs / original，你必须在gc'ing

filter-branch also keeps backup refs in .git/refs/original, which you'll also have to remove before gc'ing
