From 83c73c39c5c6b115fc80e6133433b70753499bab Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 23 Jan 2019 10:16:26 +0200 Subject: tests: Test event dispatcher interruption by signal MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a test to verify that the event dispatcher correctly restarts event processing when interrupted by a signal. The test currently fails as this feature isn't implemented.
