Subject: [PATCH 02/15] python/aqmp: add .empty() method to EventListener
Date: Fri, 17 Sep 2021 01:40:34 -0400	[thread overview]
Message-ID: <20210917054047.2042843-3-jsnow@redhat.com> (raw)
In-Reply-To: <20210917054047.2042843-1-jsnow@redhat.com>

Synchronous clients may want to know if they're about to block waiting
for an event or not. A method such as this is necessary to implement a
compatible interface for the old QEMUMonitorProtocol using the new async
internals.
