perf scripting perl: Force to use stdbool

2015-01-21T13:05:00+00:00

When building perf for arm64 I hit a warning (and be treated as an
error) like below:

 aarch64-oe-linux-gcc -o .../scripts/perl/Perf-Trace-Util/Context.o -c -Wbad-function-cast \
         ... scripts/perl/Perf-Trace-Util/Context.c

 In file included from .../usr/lib64/perl/5.14.3/CORE/perl.h:2464:0,
                  from Context.xs:23:
 /.../usr/lib64/perl/5.14.3/CORE/handy.h:108:0: error: "bool" redefined [-Werror]
  #  define bool char
  ^

    #define bool _Bool

Looks like the failure is caused by arm64 uapi/asm/sigcontext.h, which
includes linux/types.h while other archs not.

Current perl consider this problem:

http://perl5.git.perl.org/perl.git/commit/bd31be4baa3ee68abdb92c0db3200efe0fad903b

However there are users which use old version of perl.

This patch includes stdbool.h before Context.xs and define HAS_BOOL to
prevent perl'e headers define its own 'bool'. Code is learn from perl's
git tree.

perf script: Fix broken include in Context.xs

perf script: Finish the rename from trace to script

2010-12-25T13:29:02+00:00

The scripts have calls to 'perf trace' that need to be converted to 'perf script', do it.

This problem was introduced in 133dc4c.

perf trace/scripting: Add rwtop and sctop scripts

2010-04-14T09:56:08+00:00

A couple of scripts, one in Python and the other in Perl, that
demonstrate 'live mode' tracing.  For each, the output of the
perf event stream is fed continuously to the script, which
continuously aggregates the data and reports the current results
every 3 seconds, or at the optionally specified interval.  After
the current results are displayed, the aggregations are cleared
and the cycle begins anew.

To run the scripts, simply pipe the output of the 'perf trace
record' step as input to the corresponding 'perf trace report'
step, using '-' as the filename to -o and -i:

 $ perf trace record sctop -o - | perf trace report sctop -i -

Also adds clear_term() utility functions to the Util.pm and
Util.py utility modules, for use by any script to clear the
screen.

perf/scripts: Move common code out of Perl-specific files

2010-02-23T19:37:29+00:00

This stuff is needed by all scripting engines; move it from the Perl
engine source to a more common place.

perf trace/scripting: Add Fedora libperl install note to doc

2009-11-30T08:04:01+00:00

Fedora needs perl-ExtUtils-Embed for Perl scripting, which also
brings along libperl-devel; note this info for the convenience
of Fedora users.

perf trace/scripting: Fix Perl common_* access functions

2009-11-30T08:04:00+00:00

The common_* functions (e.g. common_pc(), etc) are exported as
common_* but named get_common_*, resulting in unresolved
subroutine errors when executing scripts.

Make the internal and external names match.

perf trace: Add interface to access perf data from Perl handlers

2009-11-28T09:04:27+00:00

The Perl scripting support for perf trace allows most of a trace
event's data to be accessed directly as handler arguments, but
not all of it e.g. the less common fields aren't passed in.  To
give scripts access to the other fields and/or any other data or
metadata in the main perf executable that might be useful, a way
to access the C data in perf from Perl is needed; this patch
uses the Perl XS facility to do it for the common_xxx event
fields not passed to handler functions.

Context.pm exports three functions to Perl scripts that access
fields for the current event by calling back into perf:
common_pc(), common_flags() and common_lock_depth().  Support
for common_flags() field values was added to Core.pm and a
script used to sanity check these and other basic scripting
features, check-perf-trace.pl, was also added.
