perf diff: Color the Weighted Diff column

2014-01-13T14:38:25Z

In $ perf diff -c wdiff:M,N color the numbers in the Weighted Diff column using color_snprintf(), picking the colors using get_percent_color().

perf diff: Color the Ratio column

2014-01-13T14:37:17Z

In $ perf diff -c ratio color the Ratio column using value_color_snprintf(), a new function that operates exactly like percent_color_snprintf(). At first glance, it looks like percent_color_snprintf() can be turned into a non-variadic function simplifying things; however, 53805ec (perf tools: Remove cast of non-variadic function to variadic, 2013-10-31) explains why it needs to be a variadic function.

perf diff: Color the Delta column

2014-01-13T14:36:46Z

Color the numbers in the Delta column using percent_color_snprintf(). Generalize the coloring function so that we can accommodate all three comparison methods in future patches: delta, ratio, and wdiff.

perf evlist: Introduce evlist__for_each() & friends

2014-01-13T13:06:25Z

For the common evsel list traversal, so that it becomes more compact. Use the opportunity to start ditching the 'perf_' from 'perf_evlist__', as discussed, as the whole conversion touches a lot of places, lets do it piecemeal when we have the chance due to other work, like in this case.

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 kvm: Make perf kvm diff support --guestmount.

2013-12-09T18:24:25Z

In manpage of perf-kvm, --guestmount is supported by diff command, but it does not work well. This patch change the extend the checking in buildid-diff from guestkallsyms or guestmodules to perf_guest. Then this checking can cover the all cases perf kvm is used for.

perf hists: Consolidate histsadd_*entry()

2013-11-04T23:59:09Z

The __hists__add_{branch,mem}_entry() does almost the same thing that __hists__add_entry() does. Consolidate them into one.

perf tools: Stop using 'self' in some more places

2013-10-23T12:55:37Z

As suggested by tglx, 'self' should be replaced by something that is more useful.

perf tools: Add data object to handle perf data file

2013-10-21T20:33:24Z

This patch is adding 'struct perf_data_file' object as a placeholder for all attributes regarding perf.data file handling. Changing perf_session__new to take it as an argument. The rest of the functionality will be added later to keep this change simple enough, because all the places using perf_session are changed now.
