perf tools: Remove unnecessary ctype.h inclusion

2012-01-30T20:37:35+00:00

There are unnecessary #include  out there, and they might cause
a nasty build failure in some environment. As we already have most of
ctype macros in util.h, just get rid of them.

A few of exceptions are util/symbol.c which needs isupper() macro util.h
doesn't provide and perl scripting support code which includes ctype.h
internally.

perf tools: Resolve machine earlier and pass it to perf_event_ops

2011-11-28T12:39:12+00:00

Reducing the exposure of perf_session further, so that we can use the
classes in cases where no perf.data file is created.

perf session: Pass evsel in event_ops->sample()

2011-03-23T22:28:58+00:00

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).

perf tool: Fix gcc 4.6.0 issues

2011-02-07T14:41:41+00:00

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.

perf: Rename 'perf trace' to 'perf script'

2010-11-16T18:37:44+00:00

Free the perf trace name space and rename the trace to 'script' which is a
better match for the scripting engine.

perf scripts python: Give field dict to unhandled callback

2010-06-01T09:12:35+00:00

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.

perf/trace/scripting: don't show script start/stop messages by default

2010-05-10T22:50:59+00:00

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

perf/scripts: Tuple was set from long in both branches in python_process_event()

2010-04-02T19:32:16+00:00

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.

perf/scripts: Remove unnecessary PyTuple resizes

2010-02-25T03:07:49+00:00

If we know the size of a tuple in advance, there's no need to resize
it - start out with the known size in the first place.
