减少 git 存储库大小 [英] Reduce git repository size

问题描述

我试图寻找一个关于减少 repo 大小的好教程，但没有找到.我如何减少我的 repo 大小...大约 10 MB，但问题是 Heroku 只允许 50 MB，而且我还没有完成我的应用程序的开发.

I tried looking for a good tutorial on reducing repo size, but found none. How do I reduce my repo size...it's about 10 MB, but the thing is Heroku only allows 50 MB and I'm no where near finished developing my app.

我已经在 .gitignore 中添加了常见的可疑对象(日志、供应商、文档等).虽然我最近才加了.gitignore.

I added the usual suspects (log, vendor, doc etc) to .gitignore already. Although I only added .gitignore recently.

有什么建议吗?

推荐答案

git gc --aggressive 是强制修剪过程发生的一种方法(可以肯定的是:git gc --aggressive --prune=now).您有其他命令要清理回购也是.但不要忘记，有时 git gc 单独可以 增加仓库的大小！

git gc --aggressive is one way to force the prune process to take place (to be sure: git gc --aggressive --prune=now). You have other commands to clean the repo too. Don't forget though, sometimes git gc alone can increase the size of the repo!

也可以用在filter-branch之后，标记一些要从历史记录中删除的目录(进一步增加空间)；请参阅此处.但这意味着没有人从您的公共回购中提取.filter-branch 可以在 .git/refs/original 中保留备份 refs，这样目录也可以被清理.

It can be also used after a filter-branch, to mark some directories to be removed from the history (with a further gain of space); see here. But that means nobody is pulling from your public repo. filter-branch can keep backup refs in .git/refs/original, so that directory can be cleaned too.

最后，正如本评论中提到的和这个问题；清理 reflog 会有所帮助:

Finally, as mentioned in this comment and this question; cleaning the reflog can help:

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

更完整但可能更危险的解决方案是从 git 存储库中删除未使用的对象

An even more complete, and possibly dangerous, solution is to remove unused objects from a git repository

2021 年 2 月更新，十一年后:新的 git maintenance 命令(手册页) 应该取代 git gc 和 可以安排.

Update Feb. 2021, eleven years later: the new git maintenance command (man page) should supersede git gc, and can be scheduled.
