我在这里看到过类似的问题，但是当您处理缓慢/不稳定的网络连接时，它们并没有真正解释如何克隆大型git存储库。
到目前为止，基本上我所做的是：
$ git clone --depth=1 https://salsa.debian.org/kernel-team/linux.git/
Cloning into 'linux'...
remote: Enumerating objects: 1089, done.
remote: Counting objects: 100% (1089/1089), done.
remote: Compressing objects: 100% (738/738), done.
remote: Total 1089 (delta 48), reused 651 (delta 31)
Receiving objects: 100% (1089/1089), 1.49 MiB | 66.00 KiB/s, done.
Resolving deltas: 100% (48/48), done.
该命令只创建了最后一次提交的shallow本地存储库：
$ git log --all --oneline
7d94791 (grafted, HEAD -> refs/heads/master, refs/remotes/origin/master, refs/remotes/origin/HEAD) Update to 4.20.7
现在我应该使用以下命令之一（或它们的某种组合）：
$ git fetch --deepen=100
$ git fetch --depth=100
第一个将获取另外100个提交，因此本地存储库现在将具有101个提交。第二个将获取99个提交，本地存储库将总共有100个提交。
我一直在使用价值观，直到最终得到这个：
$ git fetch --depth=10000
remote: Total 0 (delta 0), reused 0 (delta 0)
$ git fetch --unshallow
fatal: --unshallow on a complete repository does not make sense
它说我有一个完整的存储库，但事实并非如此。阅读git stats（在线），我可以看到它具有 13,746次提交，29个分支，1,418个，标签和 2.2 GB 文件。根据类似问题中的信息，如果这是完整克隆，则应该有--depth=13746，但没有事件有10000。
这里的问题出在29 Branches中，而我仅克隆了master。
这里的问题实际上是：如何以类似的方式克隆其余分支，以便获得整个存储库？
我注意到在.git/config文件中，我具有以下内容：
[remote "origin"]
url = https://salsa.debian.org/kernel-team/linux.git/
fetch = +refs/heads/master:refs/remotes/origin/master
当我将第三行更改为：
fetch = +refs/heads/*:refs/remotes/origin/*
它将获取其余的分支。
我也尝试使用以下内容：
fetch = +refs/heads/master:refs/remotes/origin/master
fetch = +refs/heads/sid:refs/remotes/origin/sid
仅提取了sid分支：
$ git remote update && git status
Fetching origin
remote: Enumerating objects: 209, done.
remote: Counting objects: 100% (209/209), done.
remote: Compressing objects: 100% (72/72), done.
remote: Total 209 (delta 92), reused 199 (delta 89)
Receiving objects: 100% (209/209), 260.34 KiB | 136.00 KiB/s, done.
Resolving deltas: 100% (92/92), done.
From https://salsa.debian.org/kernel-team/linux
* [new branch] sid -> origin/sid
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean
现在我有
$ git branch -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/master
remotes/origin/sid
我认为这里缺少一些内容，但是我真的不知道该做什么以及是否仅添加另外fetch = +refs...行是正确的方法。
我可以通过以下方式获取分支列表：
$ git ls-remote --heads origin

如何添加和获取（以某种自动化方式）每个分支？
