"""Verifies the commit hash for an interim Zaqar build.
This function may be used to verify that the version of the zaqar
package, as imported from an environment's site-packages, is the
expected build. This allows continuous integration scripts to
detect out-of-date installations of the package.
Note that this function will ALWAYS return False for Zaqar packages
that were not installed from git.
:param expected: The expected commit object name. May be either a full
or abbreviated SHA hash. If abbreviated, at least 7 digits are
required.
:returns: True if the package's version string contains a hash, and
that hash matches `expected`. Otherwise returns False.
"""
# NOTE(kgriffs): Require 7 digits to avoid false positives. In practice,
# Git's abbreviated commit oject names will always include at least
# 7 digits.

# NOTE(kgriffs): Git usually abbreviates hashed to 7 digits, but also
# check 8 digits in case git decides just 7 is ambiguous. Accordingly,
# try the longer one first since it is more specific than the other.
