* Revert "Fix QtSharedPointer::ExternalRefCountData object leaks"J-P Nurmi2015-12-232-11/+2
| | | | | | | | | | This reverts commit 839d2d3e2368bc8e107d22203b0611c852f54319, which has been causing crashes in qtquickcontrols2 auto tests and making it nearly impossible to integrate anything over the past few days.

| | | | | | | | | | | Call destroyObject() for every QV4::Heap::QObectWrapper object in heap in QV4::MemoryManager::sweep() to make sure the QPointer object contained in QV4::Heap::QObjectWrapper is properly destructed. We also keep track of QObjectWrapper in QV4::Heap::ModelObject to make sure we destory them in QV4::MemoryManager::sweep() Change-Id: I3b3e96cfc300c2e21ab691762879ac2970afa90c Reviewed-by: Simon Hausmann <simon.hausmann@theqtcompany.com>

* Improve algorithm to handle GC of StringsLars Knoll2015-09-251-6/+7
| | | | | | | | | | | | The old algorithm could lead to excessive garbage collection in cases where lots of strings are being created. The new algorithm is a bit more agressive in doubling the GC limit for string data. This doubles the performance of both the v8 regexp and splay benchmarks.

* Inline property data into the objectLars Knoll2015-09-221-9/+52
| | | | | | | | | | | | Append the part of the objects property data that is known ad instantiation time to the object itself and by that avoid creating a separate MemberData. Saves some memory and should speed up object creation. Currently implemented only for Object and ArrayObject.

* Store the stack of executioncontext's on the JS stackLars Knoll2015-09-151-3/+3
| | | | | | | | | | | | | | | | This saves one pointer per allocated execution context. Now every execution context that is pushed, allocates two Values on the js stack. One contains the context itself, the other one the offset to the parent context. Things are a bit tricky for with and catch scopes, as those are called from the generated code, and can't open a Scope anymore. In addition, all methods iterating over the js stack frames need to work with ExecutionContext pointers, not ScopedContext's.

* Fix performance of ListModel::get()Simon Hausmann2015-08-191-4/+2
| | | | | | | | | | | | | | | | | | When called, the function would return a full-fledged QObject that maps the list element addressed. It would contain a _copy_ of all values in the list item and it would create a new meta-object for each list element. This function exists for the JavaScript API, and therefore we now return a much more lightweight object. For compatbility reasons it still has to be a QObject, but the meta-object of it is created on-demand, i.e. only when accessing properties from the C++ side or when connecting to the changed signal of a property. Otherwise the JavaScript wrapper will return the live values from the model without copying them.
