Subject: [PATCH v2 17/26] qapi: Move context-free checking to the proper place
Date: Fri, 27 Sep 2019 15:46:30 +0200	[thread overview]
Message-ID: <20190927134639.4284-18-armbru@redhat.com> (raw)
In-Reply-To: <20190927134639.4284-1-armbru@redhat.com>

QAPISchemaCommand.check() and QAPISchemaEvent().check() check 'data'
is present when 'boxed': true.  That's context-free.  Move to
check_command() and check_event().

Tweak the error message while there.

check_exprs() & friends now check exactly what qapi-code-gen.txt calls
the second layer of syntax.
