"git status branch" reports detached HEAD

[mknejp]

Hi,

we used to use "git lfs clone" in a custom clone script but started getting "git lfs clone is deprecated" warnings.
So we ditched our custom script in favor of the appveyor default, however we now have problems getting the branch number in our build scripts. The branch number is part of our detailed version and is read using "git status branch" (so that it works everywhere, not just on the CI).

However it seems that even though appveyor does use the branch name in the clone, it does not use it in the checkout:

git clone -q --branch=XXX git@bitbucket.org:user/repo.git C:\projects\project
Filtering content:  ...
git checkout -qf 01234abcd...

I don't know why the git checkout command is there but that's responsible for dropping us on a detached HEAD. If the clone script already has a --branch specified, what is the purpose of git checkout?

Thanks

Makes sense. After all, if one needs the first commit in the branch git log --pretty=format:%H -1 or git log --pretty=format:%h -1 can be used...

git checkout -qf 01234abcd... is required to checkout build's specific commit; otherwise you'll be getting the latest commit on XXX branch.

Understood. Although I can understand the mentioned issue, you need the checkout for when several commits are done faster than the builds run, assuming a build is done for every commit.

How about doing git reset --hard -q 01234abcd... instead? Would that not also rewind the current branch's head?
