Migrated issue, originally created by Christopher Sang (csang)

Run a downgrade on an initially empty db, using a command like:

python -Wall `which alembic` downgrade base

The following DeprecationWarning occurs:

/usr/local/lib/python3.6/site-packages/alembic/script/base.py:348: DeprecationWarning: generator 'RevisionMap._iterate_revisions' raised StopIteration
    migration.MigrationStep.downgrade_from_script(

Environment:

alembic 0.9.5
python 3.6.2
postgresql 9.6.5 (probably does not make a difference)
psycopg2 2.7.3.1

Clean up all Python 3.6 warnings

Fixed a few Python3.6 deprecation warnings by replacing StopIteration with return, as well as using getfullargspec() instead of getargspec() under Python 3.

Additionally fixed docstrings with backslashes needing r'', filehandles not explicitly closed, accommodate for .pyc files not necessarily present.
