* Fix failing assertion inside MSVC STL in debug buildsSimon Hausmann2014-05-211-2/+2
| | | | | | | | | | | | | | | When using FunctionObject's call() method, we use std::copy to copy the arguments over to the new call context. Unfortunately std::copy has an assertion in there to check that we're not copying out of bounds. What the STL doesn't know is that the Value args[1] array is dynamically allocated and easily expands beyond just one entry. Fall back to copying by hand to work around this issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 5dc7649f5ad7dca6e13707e827d001c3f118a6ef caused this regression, as a result of lazy binding evaluation and self-referencing objects: import QtQml 2.0 QtObject { property QtObject objectRef : subObject property QtObject blah: QtObject { id: subObject property int value: 42 property int blah: objectRef.value } } When blah is evaluated, we now lazily initialize objectRef - as opposed to previously throwing an exception and then when objectRef gets initialized we re-evaluate blah due to its dependency. So while evaluating "objectRef.value" for blah, we initialize objectRef by evaluating "subObject", and after doing that we write the "objectRef" property. That triggers a change notification, and since the objectRef reference for blah is a compile-time known dependency, the change notification triggers a re-evaluation of "blah", which is the binding loop. What's wrong here is that we register the pre-defined captures before the code execution, when we should register them after the evaluation, or strictly speaking after flushing pending bindings, like it is the case for individual properties in bindings where we could not pre-determine the depenencies.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Store a simple vector of Values in the array data, instead of a Vector of Property's. This halfes the memory consumption on 64bit and simplifies our code. If an indexed property gets converted to an accessor property, we simply convert the ArrayData into a SparseArrayData. Add support in SparseArrayData to allocate double slots (two Value's) to hold a full Property in case someone sets an accessor on an indexed property. Some methods still return a Property*, but this is safe, as only the first Value in the Property pointer will ever get accessed if the Property doesn't contain an accessor.
