perf evlist: Introduce poll method for common code idiom

2014-09-25T19:46:55Z

Since we have access two evlist members in all these poll calls, provide a helper. This will also help to make the patch introducing the pollfd class more clear, as the evlist specific uses will be hiden away perf_evlist__poll().

perf tools: Move pr_* debug macros into debug object

2014-07-17T15:58:39Z

Moving pr_* debug macros to have it with in same object as debug variables, becase we will change them to use verbose variable in next patch.

perf record: Rename --no-delay to --no-buffering

2014-01-14T20:57:04Z

That is how the option summary describes it and so that we can free --delay to replace --initial-delay and then be consistent with stat's --delay equivalent option.

perf evlist: Auto unmap on destructor

2014-01-13T13:06:22Z

Removing further boilerplate after making sure perf_evlist__munmap can be called multiple times for the same evlist.

perf evlist: Close fds on destructor

2014-01-13T13:06:22Z

Since it is safe to call perf_evlist__close() multiple times, autoclose it and remove the calls to the close from existing tools, reducing the tooling boilerplate.

perf evlist: Move destruction of maps to evlist destructor

2014-01-13T13:06:21Z

Instead of requiring tools to do an extra destructor call just before calling perf_evlist__delete.

perf tools: Rename 'perf_record_opts' to 'record_opts

2013-12-19T17:43:45Z

Reduce typing, functions use class__method convention, so unlikely to clash with other libraries. This actually was discussed in the "Link:" referenced message below.

perf evsel: Remove idx parm from constructor

2013-11-11T18:56:39Z

Most uses of the evsel constructor are followed by a call to perf_evlist__add with an idex of evlist->nr_entries, so make rename the current constructor to perf_evsel__new_idx and remove the need for passing the constructor for the common case. We still need the new_idx variant because the way groups are handled, with evsel->nr_members holding the number of entries in an evlist, partitioning the evlist into sublists inside a single linked list. This asks for a clarifying refactoring, but for now simplify the non parser cases, so that tool writers don't have to bother with evsel idx setting.

perf tools: Fixup mmap event consumption

2013-10-28T19:06:00Z

The tail position of the event buffer should only be modified after actually use that event. If not the event buffer could be invalid before use, and segment fault occurs when invoking perf top -G.
