perf tools: Use zfree to help detect use after free bugs

2013-12-27T20:08:19Z

Several areas already used this technique, so do some audit to consistently use it elsewhere.

perf tools: Finish the removal of 'self' arguments

2013-11-05T18:32:36Z

They convey no information, perhaps I was bitten by some snake at some point, complete the detox by naming the last of those arguments more sensibly.

perf hists: Add color overhead for stdio output buffer

2013-10-28T19:05:59Z

Following commit tightened up the buffer size for output to strict width of used format columns: 99cf666 perf hists: Fix formatting of long symbol names This works fine until you hit color overhead output which places extra bytes into output buffer. We need to account for color overhead in the output buffer. Adding maximum color byte size to the output buffer size.

perf hists: Fix formatting of long symbol names

2013-09-05T19:18:28Z

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).

perf tools: Move hist_entry__period_snprintf into stdio code

2013-07-12T16:54:18Z

Moving hist_entry__period_snprintf function into stdio code and making it static, as it's no longer used anywhere else.

perf tools: Add struct perf_hpp_fmt into hpp callbacks

2013-07-12T16:53:57Z

Adding 'struct perf_hpp_fmt' into hpp callbacks, so commands can access their private data. It'll be handy for diff command in future to be able to access file related data for each column.

perf report: Add --percent-limit option

2013-05-28T13:24:01Z

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.

perf hists: Rename hists__fprintf_nr_events to events_stats__fprintf

2013-01-24T19:40:11Z

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

perf hists: Introduce perf_hpp__list for period related columns

2012-12-09T11:46:05Z

Adding perf_hpp__list list to register and contain all period related columns the command is interested in. This way we get rid of static array holding all possible columns and enable commands to register their own columns. It'll be handy for diff command in future to process and display data for multiple files.
