From 9cba9844547731d2f14d79485c43192ffaa37b76 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 25 Oct 2016 01:21:10 +0900 Subject: perf hist browser: Fix hierarchy column counts The perf report/top on TUI supports horizontal scrolling using LEFT and RIGHT keys. But it calculate the number of columns incorrectly when hierarchy mode is enabled so that keep pressing RIGHT key can make the output disappeared. In the hierarchy mode, all sort keys are collapsed into a single column, so it needs to be applied when calculating column numbers.

Looking at the code, I found a dubious code which affects the symptoms. When --hierarchy option is used, the last column length might be inaccurate since it skips to update the length on leaf entries. I cannot remember why it did and looks like a leftover from previous version during the development. Anyway, updating the column length often is not harmful. So let's move the code out.
