From 570b1c79942b237022be3594ae3a25e7b833cb73 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Fri, 18 Apr 2014 14:47:00 -0700 Subject: test: [v2] Validate server log reading more carefully in signal-logging test Check return value from fgets and strchr instead of assuming they worked. [v2] Don't do any necessary work inside the assert call. Also make sure the return value was long enough.
