Subject: [PULL 10/15] qapi/parser: Fix token membership tests when token can be None
Date: Thu, 20 May 2021 19:52:51 +0200	[thread overview]
Message-ID: <20210520175256.1119684-11-armbru@redhat.com> (raw)
In-Reply-To: <20210520175256.1119684-1-armbru@redhat.com>

From: John Snow <jsnow@redhat.com>

When the token can be None (EOF), we can't use 'x in "abc"' style
membership tests to group types of tokens together, because 'None in
"abc"' is a TypeError.

Easy enough to fix. (Use a tuple: It's neither a static typing error nor
a runtime error to check for None in Tuple[str, ...])

Add tests to prevent a regression. (Note: they cannot be added prior to
this fix, as the unhandled stack trace will not match test output in the
CI system.)
