From aspects to TPTP [message #86072]

I need to port my aspect-based logging application to TPTP.

My application basically saves information on data exchanged between
methods calls.

I used Aspectwerkz and so i could attach my aspects with a very fine
granularity: i could select the class/method from which the method is
called and the class/method that is effectively called.

The construct I used in aspectwerkz was something like this:

<aspect class="MyAspect">
<pointcut name="pc0" expression="call(public *
package.ClassTo.*(..)) AND within( package.ClassFrom.. )" />
<advice name="myAdvide" type="before" bind-to="pc0" />
</aspect>

with this aspect i can instrument all call from
package.ClassFrom.everyMethods() to package.ClassTo.aMethod()

It seems that TPTP probes are very similar to aspects, but it also seems
to me that with probes i can only select the target but not the method
doing the call.
So, I have these consequences:
1) more code instrumented
2) I have to write code that do checks needed

I don't want to add such code.

Is there a way to have such kind of fine grainularity?

Thanks in advance

Actually you can instrument the methods that are making the call by using
callsite probes. See the following help document for more info:
Monitoring and profiling applications -> Collecting runtime data with
user-defined probes -> Probe definitions -> Probe fragements -> Probe
fragment types -> Method probes versus callsite probes

Yes, but i need to track someting like:
"all calls from p1.A.b to p2.B.*"

or

"all calls from p1.A.b"

And It seems to me that this is not possible (without adding control in
my probes).

Another question: probekit is still not working with the new agent
controller for linux (x86_64ù) and tptp versuion 4.3, right?

Thanks in advance

Yes, that's right. You can't do this with your filtering criteria. You=20
need to add some control checking to your probes in order to be able to do =

this.

There is no official support for Probekit on the new technology Agent=20
Controller for 64-bit Linux.

 Yes, that's right.  You can't do

Last couple of questions (OT i know):

There will be support for Probekit for 64-bit Linux?

Probes will remain or is a feature that will be dismissed in the future?

Is there any architectural documentation on TPTP's components or there
is only that on eclipse.org/tptp?

Thank you for all

Regards

Fabrizio

I doubt that Probekit will be dropped from TPTP in the future. There are
a number of enhancements open to support Probekit on 64-bit Linux. Here's
what I could find:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=108584
https://bugs.eclipse.org/bugs/show_bug.cgi?id=121658

Feel free to add yourself to the CC list of these bugs.
