Hello Maik,
As Michal already said, it is very nice that you would like to
contribute such a great feature :)! I am moving this discussion to PDT
development mailing group (please join via
https://dev.eclipse.org/mailman/listinfo/pdt-dev) as I think that other
team members may also add value to this topic.
As a first step I would like to describe briefly what I think we can do
to add another profiler based on Xdebug. First of all, the currently
available profiler is based on Zend Debugger and all supporting code was
moved from Zend Studio and added as a separate feature for PDT. As you
have probably already noticed, there is no common API in PDT core
plug-ins for profiling support. Everything is packed in new feature for
Zend Profiler. As I am not too familiar yet with internals for Xdebug
profiling in general (and differences with Zend Debugger profiler data)
I can not say what would be needed to create a common API that would
work for both profilers. Anyway as you already started some analysis I
guess that you will be able to tell me what is missing or would have to
be refactored to handle Xdebug profiler data.
As an entry point I suggest to take a look at
/org.eclipse.php.profile.core.engine/ and
/org.eclipse.php.profile.core.data/ packages and related
classes/interfaces (especially ProfilerDB interface which I think may be
reworked to serve both profilers as an entry point for profiling result
data). If you would be able to provide Xdebug implementation for this
interface then everything else should be a little bit straight forward.
But as I already said it would be nice if you can investigate/suggest
what need to be changed to create common API that would serve both
profilers. If you find it possible to provide such implementation we can
think about extracting some common part of API for both profilers and
moving it directly to PDT core plug-ins.
Greetings,
Bartlomiej Laczkowski
