• 9e69c2108   perf session: Pass evsel in event_ops->sample() ... Browse Code »

  Resolving the sample->id to an evsel since the most advanced tools,
  report and annotate, and the others will too when they evolve to
  properly support multi-event perf.data files.

  Good also because it does an extra validation, checking that the ID is
  valid when present. When that is not the case, the overhead is just a
  branch + function call (perf_evlist__id2evsel).

• fb7d0b3ce   perf tool: Fix gcc 4.6.0 issues ... Browse Code »

  GCC 4.6.0 in Fedora rawhide turned up some compile errors in tools/perf
  due to the -Werror=unused-but-set-variable flag.

  I've gone through and annotated some of the assignments that had side
  effects (ie: return value from a function) with the __used annotation,
  and in some cases, just removed unused code.

  In a few cases, we were assigning something useful, but not using it in
  later parts of the function.

  Free the perf trace name space and rename the trace to 'script' which is a

• c02514850   perf scripts python: Give field dict to unhandled callback ... Browse Code »

  trace_unhandled() callback does not allow to access event fields, this patch
  resolves the problem.

  It can also been used as a more pythonic and flexible way for script writters
  to demux event types

  This will for example greatly simplify pytimechart event demux.

  Only print the script start/stop messages in verbose mode - users
  normally don't care and it just clutters up the output.

• b1dcc03cb   perf/scripts: Tuple was set from long in both branches in python_process_event() ... Browse Code »

  This is a fix to the signed/unsigned field handling in the
  Python scripting engine, based on a patch from Roel Kluin.

  Basically, Python wants to use a PyInt (which is internally a
  long) if it can i.e. if the value will fit into that type. If
  not, it stores it into a PyLong, which isn't actually a long,
  but an arbitrary-precision integer variable.

  The code below is similar to to what Python does internally, and
  it seems to work as expected on the x86 and x86_64 sytems I
  tested it on.

  If we know the size of a tuple in advance, there's no need to resize
