问题描述
我有一个带有子模块的仓库.对于给定的子模块SHA，我想在存在该子模块并具有给定SHA的存储库中查找提交.
I have a repo which has a submodule. For a given SHA of the submodule, I want to find commits in the repo where this submodule exists and has the given SHA.
我该如何使用最新版本的git?
How would I do this with the most recent version of git?
推荐答案
您可以使用 git ls-tree 读取 gitlink (a )以读取子模块的SHA1:
You can use git ls-tree to read that gitlink (a special entry in the index) to read the SHA1 of a submodule:
git ls-tree HEAD mysubmodule
160000 commit c0f065504bb0e8cfa2b107e975bb9dc5a34b0398 mysubmodule
这将包括在子存储库中记录子模块的SHA1.
That will include the SHA1 at which the submodule is recorded in the parent repo.
知道，您可以将其与 git filter-branch 结合使用，使用索引过滤器(以避免每次提交都必须签出父仓库)
Knowing that, you can combine it with a git filter-branch, using an index filter (to avoid having to checkout the parent repo for each commit)
git filter-branch --prune-empty --index-filter 'git ls-tree mysubmodule' -- --all|grep <yourSHA1>
结合 git rev-list 和 git ls-tree 可能更干净:
A shell approach combining git rev-list and git ls-tree is probably cleaner:
#!/bin/sh
for r in $(git rev-list FIRST_REV..LAST_REV)
do
git ls-tree $r mysubmodule
done | grep <yourSHA1>
使用 git 2.7，您很快就会得到:
git for-each-ref --contains <SHA1>
那应该更容易.
