[RFC PATCH 2/2] status: improve info for detached HEAD after clone

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When a remote ref or a tag is checked out, HEAD is automatically
detached, and "git status" says 'HEAD detached at ...', instead of
'Not currently on any branch.'; this is done by traversing the reflog
and parsing an entry like 'checkout: moving from ... to ...'.

In certain situations, HEAD can be detached after "git clone": for
example, when "--branch" specifies a non-branch (e.g. a tag). It is
preferable to avoid displaying 'Not currently on any branch.', so
'HEAD detached at $sha1' is shown instead.
