Pull updates with git after cloned with --depth 1
提问by matec
This morning I made a shallow clone of the Linux sources
今天早上我对 Linux 源代码做了一个浅薄的克隆
git clone --depth 1 https://github.com/torvalds/linux.git
which resulted in a linuxfolder of 851Mb.
这导致了一个linux851Mb的文件夹。
Now I would like to pull the latest changes, but
现在我想提取最新的更改，但是
git pull
starts a seemly huge download. After 60Mb I'm at 3% which extrapolates to 2Gb. However, the 5 commits since my clone change only a bunch of lines.
开始一个看似巨大的下载。在 60Mb 之后，我处于 3%，推断为 2Gb。但是，由于我的克隆只更改了一堆行，所以 5 次提交。
Am I doing something wrong? What are the 2Gb that gittries to download?
难道我做错了什么？git尝试下载的 2Gb 是什么？

I think you can use --depth 1in git pulltoo, so it gets just what's needed for the newest commit in the repository.
我认为您也可以使用--depth 1in git pull，因此它可以获取存储库中最新提交所需的内容。
I don't know if the default behaviour is to pull everything missing, because my git help pullshows this option:
我不知道默认行为是否是拉出所有丢失的东西，因为我git help pull显示了这个选项：
git pull --unshallow
or
或者
git fetch --unshallow
--unshallow Convert a shallow repository to a complete one, removing all the limitations imposed by shallow repositories.
--unshallow 将浅存储库转换为完整存储库，消除浅存储库强加的所有限制。
I'm running git version 1.8.5.2 (Apple Git-48), and maybe this is some sort-of-new behaviour, and changing a bit between versions.
我正在运行git version 1.8.5.2 (Apple Git-48)，也许这是某种新行为，并且在版本之间有所改变。

Could any of the new commits be merge-commits pointing to commits not present in your tree? Perhaps --depth 1000would work better and still be small enough.
是否有任何新提交是指向树中不存在的提交的合并提交？也许--depth 1000会工作得更好，而且仍然足够小。
