Subject: [PATCH v2 15/38] qapi/common.py: move build_params into gen.py
Date: Tue, 22 Sep 2020 17:00:38 -0400	[thread overview]
Message-ID: <20200922210101.4081073-16-jsnow@redhat.com> (raw)
In-Reply-To: <20200922210101.4081073-1-jsnow@redhat.com>

Including it in common.py creates a circular import dependency; schema
relies on common, but common.build_params requires a type annotation
from schema. To type this properly, it needs to be moved outside the
cycle.
