Using 2 of the above answers (How to clone git repository with specific revision/changeset? and How to clone git repository with specific revision/changeset?) Helped me to come up with a definative. If you want to clone up to a point, then that point has to be a tag/branch not simply an SHA or the FETCH_HEAD gets confused. Following the git fetch set, if you use a branch or tag name, you get a response, if you simply use an SHA-1 you get not response. Here's what I did:- create a full working clone of the full repo, from the actual origin

cd <path to create repo>
git clone git@<our gitlab server>:ui-developers/ui.git 

然后在有趣的地方创建一个本地分支

git checkout 2050c8829c67f04b0db81e6247bb589c950afb14
git checkout -b origin_point

然后创建我的新的空白回购，我的本地副本作为它的起源

cd <path to create repo>
mkdir reduced-repo
cd reduced-repo
git init
git remote add local_copy <path to create repo>/ui
git fetch local_copy origin_point

那时我得到了这样的回应。我指出这一点是因为如果使用SHA-1来代替上面的分支，什么也不会发生，所以响应意味着它工作了

/var/www/html/ui-hacking$ git fetch local_copy origin_point
remote: Counting objects: 45493, done.
remote: Compressing objects: 100% (15928/15928), done.
remote: Total 45493 (delta 27508), reused 45387 (delta 27463)
Receiving objects: 100% (45493/45493), 53.64 MiB | 50.59 MiB/s, done.
Resolving deltas: 100% (27508/27508), done.
From /var/www/html/ui
 * branch            origin_point -> FETCH_HEAD
 * [new branch]      origin_point -> origin/origin_point

现在在我的情况下，我需要把它放回gitlab，作为一个新的repo，所以我做了

git remote add origin git@<our gitlab server>:ui-developers/new-ui.git

这意味着我可以通过使用git——git-dir=../ui/从origin_point重建我的repo。Git format-patch -k -1——stdout <sha1> | Git am -3 -k来远程拾取樱桃，然后使用Git push origin将整个lot上传到它的新家。

希望这能帮助到别人

从Git 2.5.0开始，下面描述的功能可以在服务器端通过配置变量uploadpack启用。allowReachableSHA1InWant，这里是GitHub特性请求和GitHub提交启用该特性。注意，一些Git服务器默认激活这个选项，例如Bitbucket Server从5.5+版本开始启用它。有关如何激活配置选项的示例，请参阅Stackexchange上的回答。

如果你不想获取完整的存储库，那么你可能不应该使用clone。你可以使用fetch来选择你想要获取的分支。我不是hg专家，所以我不知道-r的细节，但在git中你可以做这样的事情。

# make a new blank repository in the current directory
git init

# add a remote
git remote add origin url://to/source/repository

# fetch a commit (or branch or tag) of interest
# Note: the full history up to this commit will be retrieved unless 
#       you limit it with '--depth=...' or '--shallow-since=...'
git fetch origin <sha1-of-commit-of-interest>

# reset this repository's master branch to the commit of interest
git reset --hard FETCH_HEAD

$ git clone $URL
$ cd $PROJECT_NAME
$ git reset --hard $SHA1

再次返回到最近的提交

$ git pull

为了在线(远程)保存还原的提交，你必须强制执行origin:

git push origin -f

在一个特定的分支或标签上只克隆一个特定的提交:

git clone --depth=1 --branch NAME https://github.com/your/repo.git

不幸的是，NAME只能是分支名称或标记名称(不能提交SHA)。

省略——depth标志来下载整个历史记录，然后签出分支或标记:

git clone --branch NAME https://github.com/your/repo.git

这适用于最新版本的git(我使用2.18.0版本)。
