From 4b3d3fc7412817e76808d9ef5eff59c5713f41c5 Mon Sep 17 00:00:00 2001 From: Richard Mudgett Date: Wed, 30 Nov 2016 18:25:11 -0600 Subject: [PATCH] res_pjsip_outbound_registration.c: Filter redundant statsd reporting. Increasing the testsuite shutdown timeout before forcibly killing Asterisk allowed more events to be sent out. Some tests failed as a result. The tests/channels/pjsip/statsd/registrations failed because we now get the statsd events that a comment in the test configuration stated couldn't be intercepted. Unfortunately, we get a variable number of events because of internal status state transition races generating redundant statsd events. We were reporting redundant statsd PJSIP.registrations.state changes for internal state changes that equated to the same thing publicly. * Made update_client_state_status() filter out redundant statsd updates.
