git hooks : is there a clone hook?
提问by maxmelbin
We want to store some meta-information about the commit in an external database. During a clone or a checkout, this database should be referred and we copy the meta information to a file in the repo which is cloned. The database is required rather than just using a file is for the sake of indexing and searches etc ...
我们想在外部数据库中存储一些关于提交的元信息。在克隆或结帐期间，应该引用该数据库，我们将元信息复制到被克隆的 repo 中的文件中。数据库是必需的，而不仅仅是使用文件是为了索引和搜索等......
I thought if there is a clone hook, we could trigger this. I couldn't find the clone hooks in the sample in .git/hooks. is there one? is post-checkout hook the only possibility at client side?
我想如果有一个克隆钩子，我们可以触发它。我在 .git/hooks 中的示例中找不到克隆钩子。有吗？结帐后挂钩是客户端的唯一可能性吗？

ok, one way to do this is to use the clone --templateoption.
好的，一种方法是使用该clone --template选项。
Specify the location where the client side hooks will be stored as value to the --templateswitch. The hooks are copied to the clone, and the post-checkout hook is fired immediately!
指定客户端挂钩将作为值存储到--template交换机的位置。钩子被复制到克隆中，结帐后钩子立即被触发！

When you clonea remote repository, you can't run any client-side hooks because hooks are local to your working copy, and you're creating one from scratch. When you pullnew changes from a remote repository, git will run your local post-mergehook if it exists.
当您克隆远程存储库时，您无法运行任何客户端钩子，因为钩子对于您的工作副本是本地的，并且您是从头开始创建的。当您从远程存储库中提取新更改时，git 将运行您的本地post-merge钩子（如果存在）。
There is nothing run on the server as the result of a pulloperation. A pushoperation will trigger the servers's updateand post-updatehooks.
作为拉取操作的结果，服务器上没有运行任何内容。一推操作将触发服务器的update和post-update挂钩。
See the Git Bookfor more information.

No, there isn't any clone hook.
不，没有任何克隆钩子。

Since git version 1.6.3, the post-checkouthook runs on git-clone (when run without --no-checkout).
从 git 版本 1.6.3 开始，结帐后挂钩在 git-clone 上运行（不带 运行时--no-checkout）。
It is also run after git-clone[1], unless the --no-checkout (-n) option is used. The first parameter given to the hook is the null-ref, the second the ref of the new HEAD and the flag is always 1.
它也在 git-clone[1] 之后运行，除非使用了 --no-checkout (-n) 选项。给钩子的第一个参数是空引用，第二个参数是新 HEAD 的引用，标志总是 1。

I'm late but there is a workaround:
我迟到了，但有一个解决方法：
Capture
git cloneexecution and set a variable usingtrap set_var_on_git_clone DEBUGwhereset_var_on_git_cloneis a user-defined function. (e.g. https://gist.github.com/KeyAmam/a6afcabc3a724fc4a541aca7629c3ff6)Check the variable in
post-checkoutscript and do some stuff in the case. Clear the variable at the end of the script. (e.g. https://gist.github.com/KeyAmam/6a0e8805c0b6a662adb6bcf8118a089a)
捕获
git clone执行并使用trap set_var_on_git_clone DEBUGwhereset_var_on_git_clone是用户定义的函数设置变量。（例如https://gist.github.com/KeyAmam/a6afcabc3a724fc4a541aca7629c3ff6）检查
post-checkout脚本中的变量并在案例中做一些事情。清除脚本末尾的变量。（例如https://gist.github.com/KeyAmam/6a0e8805c0b6a662adb6bcf8118a089a）
This only works in Bash but you can do a similar thing in other shells.
这仅适用于 Bash，但您可以在其他 shell 中做类似的事情。
