Description Marius Slavescu

This is the placeholder for improvements like (it might  be split later in
several features):
- support for agent side aggregated profiling traces (similar with execution and
heap statistics workbench modes)
- support for agent side compressed call chains (with
- support for snapshot based profiling traces, snapshot interval and duration
should be configurable
- support triggered profiling traces, triggers could be set on number of calls,
new objects, base time, cumulative time for methods/classes/packages and also on
combinations of heap state and call chain state
- improved heap model (using compressed data structures)
- improved execution model (using compressed data structures)

Details will follow on each topic, also other items might be added.

Targeting to 4.2i1. Owners plese adjust for any exceptions by targeting to 4.2i2.

Bug 90951 covers the support for agent side compressed call chains item, if we decide to do this in 4.2 we can mark this bug as dependent on Bug 90951.

Bug 108646 add support for agent side aggregated profiling traces.

This two will be covered in this feature as described in the URL:
- improved heap model (using compressed data structures)
- improved execution model (using compressed data structures)

All the others will be deffered.

In 4.2i1 I've done an initial investigation of the possible techniques that can be used, the rest of the work would be done in 4.2i2.

Moved to i3 for remaining which doesn't impact the UI, the behavior will be transparent to the user.

As of TPTP 4.6.0, TPTP is in maintenance mode and focusing on improving quality by resolving relevant enhancements/defects and increasing test coverage through test creation, automation, Build Verification Tests (BVTs), and expanded run-time execution. As part of the TPTP Bugzilla housecleaning process (see http://wiki.eclipse.org/Bugzilla_Housecleaning_Processes), this enhancement/defect is verified/closed by the Project Lead since this originator of this enhancement/defect has an inactive Bugzilla account and considered to be fixed. If this enhancement/defect is still unresolved and reproducible in the latest TPTP release (http://www.eclipse.org/tptp/home/downloads/), please re-open.
