Hi Neil,
A publish/subscribe mechanism would be nice to have, at this stage I won't
be able to add this mechanism in TPTP 4.4 as we try to keep it stable, and
only blocker/critical defects should get in with minimum amount of change
associated with them.
Post 4.4 I'll bring back the discussion on the new DMS API and I would
like to provide a light way notification mechanism there.
Thanks !

Re: [tptp-tracing-profiling-tools-dev] Bug 179157
72Hi Marius,
Thanks for the quick reply. I can understand there are complexities to
solving this problem so appreciate that it will take some time to fix. I
think you are right in that EMF notifications are too heavyweight. In my
opinion the solution is therefore to create your own notification system
with a sensible subscribe/callback mechnisim. For example if I wanted to
know whenever a new method called event occurs I should be able to
subscribe to this with ease.
Personally I find the EMF stuff totally confusing and overly complex for
something that I think could be much simpler. Maybe when you consider a
fix you might consider making some sort of publish/subscribe mechnisim for
events and give it a simple interface so not so smart people like myself
can get a hold on profiling events!
Cheers

Hi Neil,
Thanks for your interest and help to TPTP.
I'm working on this and other memory leak problems, I plan to have this
fixed in TPTP 4.4 as this has been a long standing problem.
There are two sides of this problem:
- show progress in the Profiling Monitor view
- automatically refresh the views at specific intervals
Because we need to handle large amounts of data we tried to avoid EMF
notification (which could give us the most detailed notification events)
for two reasons:
- adds processing overhead (also you need to aggregate the events
in order to create a high level notification event)
- adds footprint overhead (an adapter needs to be added to the
adapters list each objects that needs to be monitored)
Thanks !

[tptp-tracing-profiling-tools-dev] Bug 179157
Hi Guys,
Has anyone made any progress on bug 179157
https://bugs.eclipse.org/bugs/show_bug.cgi?id=179157 185 or at least
thought about it?
I think it's important because it represents a rather big hole in the
design of the TPTP GUI plugins. If TPTPs own GUI can't work out a nice
way to get updates from the profiling and update its view how is
anyone else meant to do any better?
Regards,
Neil
