* Avoid crash when a QML signal is connected to a non-void slotJ-P Nurmi2013-10-221-5/+3
| | | | | | | | | | Don't pass a QVariant pointer for the return value when we're not interested in it and the return type might not even be a QVariant (that would be only true for QML methods).

* Fix performance regression when doing property lookups for non-existant ↵Simon Hausmann2013-10-161-1/+1
| | | | | | | | | | | | | | | | | properties Commit 84627464eb11ca1149d46946b12e3c82eb54a8bf introduced a performance regression of falling back to reading the QMetaObject, when the lookup for a property in QML failed, after we've tried in the property cache. This is very very expensive to do and was only due to QQmlPropertyMap not correctly invalidating the property cache. Instead remove the property cache from the property map's QObject and on the lookup side rely on the property cache being correct in the result (positive or negative).

* Change exception handling APISimon Hausmann2013-10-021-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the exception handling API in the engine slightly, encapsulating any use of direct throw statements and catch blocks with concrete types. In the future we need to be able to change the way these are implemented, in order to ensure that the correct stack unwinding code is triggered for throw and re-throw. This patch separates the C++ exception object thrown from the V4 exception (that includes value, throwing context pointer) and stores the latter inside the engine. In order for that to compile, ExecutionEngine::StackTrace and StackFrame had to move into the QV4 namespace directly. In addition the syntax for catching exceptions changes from try { ... } catch (QV4::Exception &ex) { ex.accept(context); QV4::ScopedValue exceptionValue(scope, ex.value()); } to try { ... } catch (...) { QV4::ScopedValue exception(scope, context->catchException()); } Context::catchException() checks if there's a "current" exception in the engine, and if not assumes that we caught an unrelated exception and consequently re-throws. partiallyUnwind() is also gone and replaced with rethrowException(), in order to encapsulate the re-throw. Lastly, in the future nesting try/catch blocks isn't going to be possible due to limitations in the common C++ ABI with regards to foreign exceptions.
