如何删除像VSTS这样的远程git存储库中的悬空提交 [英] How to remove dangling commits in remote git repository like VSTS

问题描述

我一直在尝试通过将一些文件移动到git LFS来减小Git存储库的大小.再有几百个命令，这是git LFS中的文件，在我的git commit中不再包含这些文件的历史记录.

I've been trying to decrease the size of my Git repository by moving some files to git LFS. A few 100 commands further, here we are with files in git LFS and no more history of these files in my git commits.

但是，每当克隆存储库时，我仍会下载约3gb的对象.我通过在Visual Studio Team Services中创建一个新的存储库来解决此问题，然后在本地对存储库进行修剪和垃圾回收，然后将其推送到该存储库中，该存储库已减小到300mb. (在本文中本地找到的执行此操作的命令:

However, whenever I clone the repository I am still downloading about 3gb of objects. I worked around this issue by creating a new repository in Visual Studio Team Services and after pruning and garbage collecting my repository locally, then doing a push to there, it was reduced to 300mb. (Command to do this locally found in this post: Git: what is a dangling commit/blob and where do they come from?)

但是我无法想象您总是必须删除/重新创建一个完整的存储库才能删除悬空的提交.

However I can't imagine that you always have to delete / recreate a complete repository to remove dangling commits.

我还尝试过执行git init，然后将其推送到现有存储库中，但这只会进一步增加对象数.

What I also tried was doing a git init, and then pushing that over the existing repository, but it only increased the object count further.

对于同样遇到类似问题的任何人，这些都是我执行的创建新存储库而无需悬而未决提交的命令，但是我想了解如何在现有存储库中执行此操作而不必删除它:

For anyone also running into similar issues, these were the command I executed to create a new repository without dangling commits, I would however like to find out how to do this in the existing repository without having to delete it:

git clone https://avavedse.visualstudio.com/Test/_git/TestRepository
cd blahblah
git reflog expire --expire=now --all
git gc --prune=now
git remote add newrepo https://avavedse.visualstudio.com/Test/_git/TestRepositoryNewEdition
git push newrepo

推荐答案

这可能是 GitHub将定期垃圾收集无法从顶级引用访问的对象.因此，随着时间的流逝，它们会消失.但这不能保证.这是我在此找到的最好的信息.

GitHub will periodically garbage collect objects that cannot be reached from a top-level reference. So over time, they'll disappear. But this is not guaranteed. That's the best info I've found on this.

您可以手动将reflog的到期日期现在更正，然后运行垃圾收集器:

You can manually correct reflogs expiry date to now and run garbage collector:

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

但这只会影响本地存储库.

But this will only affect the local repo.

很明显，垃圾收集器远非理想，因为除非您不介意删除和创建新的回购协议并丢失所有问题，拉取请求等，否则您必须联系

Apparently, the garbage collector is far from being ideal, insomuch that unless you don't mind deleting and creating a new repo and losing all issues, pull requests, etc., you have to contact Github Support :

您可以永久删除缓存的视图和对 通过联系GitHub支持在GitHub上的请求中获取敏感数据 或GitHub高级支持. ^{[docs.github.com]}

you can permanently remove cached views and references to the sensitive data in pull requests on GitHub by contacting GitHub Support or GitHub Premium Support.^{[docs.github.com]}
