为什么我的git存储库如此之大？ [英] Why is my git repository so big?

问题描述

145M = .git / objects / pack /

我写了一个脚本，将每次提交和提交的差异大小加起来，每个分支的尖端。我得到了129MB，这是没有压缩，没有考虑分支机构中的相同文件以及分支机构之间的共同历史记录。

Git考虑到了所有这些因素，所以我期望得到更多较小的存​​储库那么为什么.git这么大？

我已经完成：

  git fsck --full 
 git gc --prune = today --aggressive 
 git repack 
  

要回答关于多少个文件/提交，我有19个分支，每个分支大概有40个文件。
287提交，使用：

  git log --oneline --all | wc -l 
  

不应该花费10兆字节来存储有关此信息。

git remote add ... 和 git remote update ）。删除不需要的远程参考，分支和标签后，我的存储库中仍有1.4GB（！）的浪费空间。我只能用 git clone file：/// path / to / repository 克隆它。请注意，在克隆本地存储库时， file：// 会产生不同的效果 - 只有被引用的对象被拷贝到整个目录结构中，而不是整个目录结构中。 b
$ b

编辑：这是Ian的一个班轮，用于重新创建新回购中的所有分行：

  d1 =＃原始回购
 d2 =＃新回购（必须已经存在）
 cd $ d1 
 for $ in $（git branch | cut -c 3-）
 do 
 git checkout 
 $ bx = $（git rev-parse HEAD）
 cd $ d2 
 git checkout -b $ b $ x 
 cd $ d1 
完成
  

145M = .git/objects/pack/

I wrote a script to add up the sizes of differences of each commit and the commit before it going backwards from the tip of each branch. I get 129MB, which is without compression and without accounting for same files across branches and common history among branches.

Git takes all those things into account so I would expect much much smaller repository. So why is .git so big?

I've done:

git fsck --full
git gc --prune=today --aggressive
git repack

To answer about how many files/commits, I have 19 branches about 40 files in each. 287 commits, found using:

git log --oneline --all|wc -l

It should not be taking 10's of megabytes to store information about this.

解决方案

I recently pulled the wrong remote repository into the local one (git remote add ... and git remote update). After deleting the unwanted remote ref, branches and tags I still had 1.4GB (!) of wasted space in my repository. I was only able to get rid of this by cloning it with git clone file:///path/to/repository. Note that the file:// makes a world of difference when cloning a local repository - only the referenced objects are copied across, not the whole directory structure.

Edit: Here's Ian's one liner for recreating all branches in the new repo:

d1=#original repo
d2=#new repo (must already exist)
cd $d1
for b in $(git branch | cut -c 3-)
do
    git checkout $b
    x=$(git rev-parse HEAD)
    cd $d2
    git checkout -b $b $x
    cd $d1
done
