From: Pekka Paalanen Date: Thu, 21 Apr 2016 13:47:20 +0000 (+0300) Subject: tests: check for NULL surface in keyboard and pointer handlers X-Git-Tag: upstream/5.0.0~1154 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fd01ba055d118eaf9b51aac2f93b9a9b697e31a8;p=platform%2Fupstream%2Fweston.git tests: check for NULL surface in keyboard and pointer handlers When a test destroys a wl_surface, it is still possible to get events referring to the destroyed surface. The surface in such cases will be NULL. Handle NULL surface gracefully in keyboard and pointer enter/leave handlers. Touch-down handler is already NULL-safe. This fixes a SEGV in a test I am writing for wp_viewport.
