From 1d90f2e707e75afdb6b644f774cf5e54dc9c33fc Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 9 Jun 2010 07:13:16 -0300 Subject: [PATCH] perf record: Don't call newt functions when not initialized MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When processing events we want to give visual feedback to the user when using the newt browser, so there are ui_progress calls in __perf_session__process_events, but those should check if newt is being used.
