`git clone --depth=1` 之后怎样获取完整仓库?

Question

只拿到了一个分支一个 commit, 再运行 fetch 也拿不到其他的分支和 commits 了.
尝试了 git fetch --all git fetch origin 无效.
用什么命令来获取完整的仓库呢?

A shallow repository (one with short history) cannot be further cloned,

Answer 1

参考 @Leedy 和 @依云 的答案, 找到有个 unshallow 参数:

git fetch --help


--unshallow
           Convert a shallow repository to a complete one, removing all the limitations imposed by shallow repositories.

Answer 2

（你们就在评论里解决问题了？）

$ git version
git version 1.8.5.3

$ git help clone
...
       --depth <depth>
           Create a shallow clone with a history truncated to the specified
           number of revisions. A shallow repository has a number of
           limitations (you cannot clone or fetch from it, nor push from nor
           into it), but is adequate if you are only interested in the recent
           history of a large project with a long history, and would want to
           send in fixes as patches.
...

可见 git shallow clone 只能 clone 当前 remote/HEAD 的目录结构，不包括历史，因此不是完整的 repo。

However，Git 1.9/2.0 已经去除了这个限制，见 https://github.com/git/git/commit/82fba2b9d39163a0c9b7a3a2f35964cbc039e1a。

--深度=

使用 --depth= 选项（请参阅 git-clone(1)）加深或缩短由 git clone 创建的浅存储库的历史记录，以从每个远程分支历史记录的提示开始指定的提交次数。未获取加深提交的标签。

Answer 4

git fetch --depth=1000000

stackoverflow上看到个解决办法，但我尝试后还是不好使。
