git：找不到blob - 想从包中删除它 [英] git: can't find blob - want to get rid of it from pack

问题描述

我有一大块我想摆脱的！
我以为我使用这个解决方案删除了​​文件：
http://dound.com/2009/04/git-forever-remove-files-or-folders-from-history/
（我用过 - --all 而不是 HEAD 以便从所有分支中删除文件）

  rm -rf .git / refs / original /&& git reflog expire --all&& 
 git gc --aggressive --prune 
  

我已经在包文件夹中查找这为为什么我的git仓库如此之大？

  $ git verify-pack -v .git / objects / pack / pack  -  *。idx |排序-k3n 
 ......最后4行：
 bc7ae9801052180b283cd81880753549f0f92587 BLOB 19464809 749446 305054873 
 acd5f09a35846bec25ebc324738139e5caabc50f BLOB 294278199 71381636 39607483

 ba9d1d27ee64154146b37dfaf42ededecea847e1 BLOB 761172819 27430741 277589990 
  

脚本 git-find-blob 是来自哪个提交有这个blob？

  $ ./git-find-blob ba9d1d27ee64154146b37dfaf42ededecea847e1 
  

但它没有找到任何东西。

任何想法如何从我的存储库中删除它？

git repack -Ad 来强制git重建您的包，并将任何不可访问的对象解包为松散对象。此时，您可以使用 git gc --prune = now 来放弃无法访问的对象。

您还应该仔细检查你是否真的过期了你的推荐日志。我相信 git reflog expire --all 将默认为90天（或30个用于不可访问的对象），因此您可能需要使用 git reflog expire - -expire-unreachable = now --all 改为（这需要在重新包装+ gc之前完成）。

I've a large blob that I want to get rid of! I thought I removed the file using this solution: http://dound.com/2009/04/git-forever-remove-files-or-folders-from-history/ (I've used -- --all instead of HEAD so that files are removed from all branches)

rm -rf .git/refs/original/ && git reflog expire --all &&  
    git gc --aggressive --prune

I've looked in the pack folder via this Why is my git repository so big?

$ git verify-pack -v .git/objects/pack/pack-*.idx | sort -k3n

The script git-find-blob is taken from Which commit has this blob?

$ ./git-find-blob ba9d1d27ee64154146b37dfaf42ededecea847e1

But it doesn't find anything.

Any ideas how to get rid of it from my repository?

解决方案

You can use git repack -Ad to force git to reconstruct your packs, and to unpack any unreachable objects into loose objects. At this point you can use git gc --prune=now to discard the unreachable objects.

You should also double-check that you actually expired your reflogs. I believe git reflog expire --all will default to 90 days (or 30 for unreachable objects), so you may want to use git reflog expire --expire-unreachable=now --all instead (this needs to be done before the repack+gc).
