了解 git 子模块和“冻结”它位于特定的提交哈希或版本
假设以下项目布局：-
mainrepo_git
|____ .git
|____ .gitmodules
|____ proj <------- directory containing the code files for mainrepo
|____ 3rdpartysourcecode <-- directory containing upstream open source code
| |____ .git
| |____ 3rdpartyfiles
|
|____ mainrepofilesanddirectories
mainrepo_git 包含我直接负责的源代码。我有读/写访问权限，可以直接推送和拉取我管理的远程 git 存储库。
嵌套在 mainrepo_git 中的是一个我命名为 3rdpartysourcecode 的目录。这个 3rdpartysourcecode 目录实际上是另一个 git 存储库（通常也称为“git 子模块”），它指向由其他开发人员管理的开源第 3 方 git 存储库。我只有读取权限。没有写权限。
有什么方法可以“冻结”与我的主存储库中所做的提交相关的 git 子模块的特定提交哈希吗？
例如，如果我在主存储库中提交（或恢复）a12ucak，我的 git 子模块也会恢复到与提交a12ucak 相关的特定版本？当我切换到提交 b349jdsak 时，我的 git 子模块也会恢复到与 b349jdsak 绑定的版本？
所以我的问题是：有一种方法可以在主存储库中的特定提交与 git 子模块中的相应提交之间创建链接吗？这样，当我在主 git 存储库中签出特定提交时，git 子模块中相应的提交也将被签出。
Assuming the following project layout:-
mainrepo_git
|____ .git
|____ .gitmodules
|____ proj <------- directory containing the code files for mainrepo
|____ 3rdpartysourcecode <-- directory containing upstream open source code
| |____ .git
| |____ 3rdpartyfiles
|
|____ mainrepofilesanddirectories
mainrepo_git contains source code I am directly responsible for. I have read/write access and can push and pull directly to a remote git repository which I manage.
Nested inside mainrepo_git is a directory which I named 3rdpartysourcecode. This 3rdpartysourcecode directory is in fact another git repo (also commonly referred to as a "git submodule") which is pointing to an open source 3rd party git repository managed by other developers. I only have read access to it. No write access.
Is there any way of 'freezing' a specific commit hash of the git submodule in relation to a commit made in my main repository?
For example, if I am at (or I revert to) commit a12ucak in my mainrepo, my git submodule also gets reverted to a specific version which I tie to commit a12ucak? And when I switch to commit b349jdsak, my git submodule also gets reverted to a version which I tie to b349jdsak?
So my question is: there is a way to create a linkage between a specific commit in the main repo with a corresponding commit in the git submodule? In such a way where when I checkout that specific commit in the main git repo, the corresponding commit in the git submodule will also be checkout.

冻结是子模块的全部要点。您确实应该阅读有关它的教程。简而言之，
git add 3rdpartysourcecode（重要的是没有尾部斜杠！）后跟一个提交，将当前签出的子模块提交锁定到超级模块提交。然后，您可以使用 git submodule update 来检查该修订版。Freezing is the whole point of submodules. You should really read a tutorial on it. In a nutshell,
git add 3rdpartysourcecode(important no trailing slash!) followed by a commit locks the currently checked out submodule commit to the supermodule commit. Then later you usegit submodule updateto check out that revision.
