2013-09-05perf hists: Fix formatting of long symbol namesArnaldo Carvalho de Melo1-6/+17
We had a hardcoded buffer for formatting histogram entries, truncating long symbol names (C++ anyone?). Fix it by using hists__sort_list_width() before formatting the first histogram entry to calculate the max lenght needed by traversing the overheads and columns lists (sort order).

The --percent-limit option is for not showing small overhead entries in the output. Maybe we want to set a certain default value like 0.1.

As this function deals exclusively with hists->stats. Preparatory patch for removing the by now needless session->hists, that should be just session->stats.

2012-10-04perf hists: Separate overhead and baseline columnsJiri Olsa1-2/+9
Currently the overhead and baseline columns are handled within single function and the distinction is made by 'baseline hists' pointer passed by 'struct perf_hpp::ptr'. Since hists pointer is now part of each hist_entry, it's possible to locate paired hists pointer directly from the passed struct hist_entry pointer. Also separating those 2 columns makes the code more obvious.

When a field separator is given, the output format doesn't need to be fancy like aligning to column length, coloring the percent value and so on.

2012-09-08perf hists: Introduce perf_hpp for hist period printingNamhyung Kim1-197/+41
Current hist print functions are messy because it has to consider many of command line options and the code doing that is scattered around to places. So when someone wants to add an option to manipulate the hist output it'd very easy to miss to update all of them in sync. And things getting worse as more options/features are added continuously. So I'd like to refactor them using hpp formats and move common code to ui/hist.c in order to make it easy to maintain and to add new features.
