如何检查当前存储库是否是顶级git repo [英] How to check if the current repository is the top level git repo

问题描述

我正在尝试检查当前仓库不是子模块而是顶层 git存储库.我尝试了以下命令:git submodule init

I'm trying to check if the current repo is not a submodule but the top level git repository. I have tried the following command: git submodule init

输出:

You need to run this command from the toplevel of the working tree.

但是它将初始化子模块.如果不是子模块而是顶层git存储库，如何在不更改存储库的情况下检查当前存储库?

But it will init the submodule. How can I check the current repository if it isn't a submodule but the top level git repository, without making a change in the repository?

推荐答案

如果您要做使用git rev-parse --show-superproject-working-tree，请确保使用Git 2.20(2018年第四季度)，以避免出现错误消息"returned path string doesn't match cwd"

If you do use git rev-parse --show-superproject-working-tree, make sure to use Git 2.20 (Q4 2018), in order to avoid the error message "returned path string doesn't match cwd"

rev-parse:--show-superproject-working-tree应该在合并期间起作用

调用'git rev-parse --show-superproject-working-tree'退出

rev-parse: --show-superproject-working-tree should work during a merge

Invoking 'git rev-parse --show-superproject-working-tree' exits with

"fatal: BUG: returned path string doesn't match cwd?"

当超级项目具有当前子模块的未合并条目时，而不是显示超级项目的工作树.

when the superproject has an unmerged entry for the current submodule, instead of displaying the superproject's working tree.

(这是在这里首次报道)

该问题是由于以下事实造成的:当子模块引用合并时 正在进行中时，"git ls-files --stage —full-name <submodule-relative-path>"为子模块返回三个单独的条目(每个阶段一个)，而不是单个条目；例如，

The problem is due to the fact that when a merge of the submodule reference is in progress, "git ls-files --stage —full-name <submodule-relative-path>" returns three seperate entries for the submodule (one for each stage) rather than a single entry; e.g.,

$ git ls-files --stage --full-name submodule-child-test
160000 dbbd2766fa330fa741ea59bb38689fcc2d283ac5 1       submodule-child-test
160000 f174d1dbfe863a59692c3bdae730a36f2a788c51 2       submodule-child-test
160000 e6178f3a58b958543952e12824aa2106d560f21d 3       submodule-child-test

此修补程序使它在使用多个条目的情况下使用第一个条目返回.

The code in get_superproject_working_tree() expected exactly one entry to be returned;
this patch makes it use the first entry if multiple entries are returned.
