def pkg_commit_hash(pkg_path):
''' Get short form of commit hash given directory `pkg_path`
There should be a file called 'COMMIT_INFO.txt' in `pkg_path`. This is a
file in INI file format, with at least one section: ``commit hash``, and two
variables ``archive_subst_hash`` and ``install_hash``. The first has a
substitution pattern in it which may have been filled by the execution of
``git archive`` if this is an archive generated that way. The second is
filled in by the installation, if the installation is from a git archive.
We get the commit hash from (in order of preference):
* A substituted value in ``archive_subst_hash``
* A written commit hash value in ``install_hash`
* git's output, if we are in a git repository
If all these fail, we return a not-found placeholder tuple
Parameters
-------------
pkg_path : str
directory containing package
Returns
---------
hash_from : str
Where we got the hash from - description
hash_str : str
short form of hash
