  perf python: Initialize 'page_size' variable (2012-10-29 12:36:46 -0200)

----------------------------------------------------------------
perf/core improvements, fixes and code move

. Initialize 'page_size' variable in the python binding, this was sent
  for perf/urgent by mistake, then when merging Ingo removed it, fixing
  the problem for perf/urgent, but when perf/urgent was merged with
  perf/core, where that initialization is needed, made the python
  binding mmap call to fail, fix it by initializing page_size again.

. Add a browser for 'perf script' and make it available from the report
  and annotate browsers. It does filtering to find the scripts that
  handle events found in the perf.data file used. From Feng Tang

. Move some functions from symbol.c to more appropriate files, creating
  dso.[ch] in the process, no code changes. From Jiri Olsa

. Fix mmap error output message for when perf_mmap fails and returns
  !-EPERM, where the default for mmap_pages, INT_MAX, was causing a
  !power of 2 error message, fix from Jiri Olsa.

[PATCH 01/14] perf tools: Move parse_events error printing to parse_events_options

[Arnaldo Carvalho de Melo]

From: Andi Kleen <ak@linux.intel.com>

The callers of parse_events usually have their own error handling.  Move
the fprintf for a bad event to parse_events_options, which is the only
one who should need it.

[PATCH 06/14] perf tools: Move dso_* related functions into dso object

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@redhat.com>

Moving dso_* related functions into dso object.

Keeping symbol loading related functions still in the symbol object as
it seems more convenient.

[PATCH 07/14] perf tools: Add a global variable "const char *input_name"

[Arnaldo Carvalho de Melo]

From: Feng Tang <feng.tang@intel.com>

Currently many perf commands annotate/evlist/report/script/lock etc all
support "-i" option to chose a specific perf data, and all of them
create a local "input_name" to save the file name for that perf data.

Since most of these commands need it, we can add a global variable for
it, also it can some other benefits:

1. When calling script browser inside hists/annotation browser, it needs
to know the perf data file name to run that script.

2. For further feature like runtime switching to another perf data file,
this variable can also help.

[PATCH 08/14] perf script: Add more filter to find_scripts()

[Arnaldo Carvalho de Melo]

From: Feng Tang <feng.tang@intel.com>

As suggested by Arnaldo, many scripts have their own usages and need
capture specific events or tracepoints, so only those scripts whose
target events match the events in current perf data file should be
listed in the script browser menu.

This patch will add the event match checking, by opening "xxx-record"
script to cherry pick out all events name and comparing them with
those inside the perf data file.

[PATCH 09/14] perf scripts browser: Add a browser for perf script

[Arnaldo Carvalho de Melo]

From: Feng Tang <feng.tang@intel.com>

Create a script browser, so that user can check all the available
scripts for current perf data file and run them inside the main perf
report or annotation browsers, for all perf samples or for samples
belong to one thread/symbol.

Please be noted: current script browser is only for report use, and
doesn't cover the record phase, IOW it must run against one existing
perf data file.

The work flow is, users can use function key to list all the available
scripts for current perf data file in system and chose one, which will
be executed with popen("perf script -s xxx.xx",) and all the output
lines are put into one ui browser, pressing 'q' or left arrow key will
make it return to previous browser.

[Arnaldo Carvalho de Melo]

From: Feng Tang <feng.tang@intel.com>

Integrate the script browser into annotation, users can press function
key 'r' to list all perf scripts and select one of them to run that
script, the output will be shown in a separate browser.

[PATCH 11/14] perf hists browser: Integrate script browser into main hists browser

[Arnaldo Carvalho de Melo]

From: Feng Tang <feng.tang@intel.com>

Integrate the script browser into "perf report" framework, users can use
function key 'r' or the drop down menu to list all perf scripts and
select one of them, just like they did for the annotation.

[PATCH 12/14] perf header: Add is_perf_magic() func

[Arnaldo Carvalho de Melo]

From: Feng Tang <feng.tang@intel.com>

With this function, other modules can basically check whether a file is
a legal perf data file by checking its first 8 bytes against all
possible perf magic numbers.

Change the function name from check_perf_magic to more meaningful
is_perf_magic as suggested by acme.

[PATCH 13/14] perf record: Fix mmap error output condition

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@redhat.com>

The mmap_pages default value is not power of 2 (UINT_MAX).

Together with perf_evlist__mmap function returning error value different
from EPERM, we get misleading error message: "--mmap_pages/-m value must
be a power of two."

Fixing this by adding extra check for UINT_MAX value for this error
condition.

[PATCH 14/14] perf python: Initialize 'page_size' variable

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

The commit 0c1fe6b:

 'perf tools: Have the page size value available for all tools'

Broke the python binding because the global variable 'page_size' is
initialized on the main() routine, that is not called when using
just the python binding, causing evlist.mmap() to fail because it
expects that variable to be initialized to the system's page size.

Fix it by initializing it on the binding init routine.
