查找特定提交的分支并检出该分支

Question

How could I easily find a branch with a particular commit and checkout to it with rugged so that I won't end with 'detached HEAD' state?

Step by step I'd like to:

• Clone repository
• repo.lookup commithash to return catch exception and exit if Rugged::OdbError: Object not found happens
• find a branch containing given commit hash
• checkout to that branch

I had the same problem but in my case was when I was trying to run a script on CircleCi, so to avoid the error you should run [[ ! -s \\"$(git rev-parse --git-dir)/shallow\\" ]] || git fetch --unshallow [[ ! -s \\"$(git rev-parse --git-dir)/shallow\\" ]] || git fetch --unshallow [[ ! -s \\"$(git rev-parse --git-dir)/shallow\\" ]] || git fetch --unshallow , maybe in your case you just should run just git fetch --unshallow and then run the task that you want.
