Subject: [PATCH v4 11/19] qapi/expr.py: Modify check_keys to accept any Collection
Date: Thu, 25 Mar 2021 02:03:48 -0400
Message-ID: <20210325060356.4040114-12-jsnow@redhat.com> (raw)
In-Reply-To: <20210325060356.4040114-1-jsnow@redhat.com>

This is a minor adjustment that allows the 'required' and 'optional'
keys fields to take a default value of an empty, immutable sequence (the
empty tuple).

This reveals a quirk of this function, which is that "a + b" is
list-specific behavior. We can accept a wider variety of types if we
avoid that behavior. Using Collection allows us to accept things like
lists, tuples, sets, and so on.

(Iterable would also have worked, but Iterable also includes things like
generator expressions which are consumed upon iteration, which would
require a rewrite to make sure that each input was only traversed once.)
