how to find out which git-branch a dependency in go.mod belongs to by command-line?

Question

I want to write a shell program to check whether all go module dependencies in my project are on newest master version in their repositories. In particular, I want to know which branch each module is on. There is a file "go.mod" containing each dependency listed as {module}-{commit time}-{commit ID} . How can I get their git-branch name from SHA-1(commit id) or other message by shell program.

I have tried go list -m -u all , only showing the newest edition if the dependency is not up-to-date. etc. git.xxx.com/project v0.0.0-20191119034146-e894bf51bdcd [v0.0.0-20200609070643-fd412b12b811] . Without cloning the repos, can go module tools resolve this quetion?

Answer 1

I couldn't figure out how to find which branch the current dependency belongs to using only go tools. But there is a way to find which branch the commit is on using git.

git clone <repo-url> && cd <repo> && git branch -a --contains <commit>
