* Reduce memory usage for object literals with integral keysSimon Hausmann2014-02-161-2/+7
| | | | | | | | | | | | Be more aggressive about using sparse arrays for object literals than for regular array handling, to reduce the memory usage in this use case. The current heuristic is that indices over 0x1000 switch to sparse, which means a simple { "3000" : "test" } creates a long vector instead of a sparse array.

| | | | | | | | | | | | | | | | This makes the ArrayData class 'pure virtual'. SimpleArrayData now contains the implementation of simple arrays. This makes the separation between simple and sparse arrays a lot cleaner. It also allows us to move len and offset from the base class into the SimpleArrayClass. This fixes some bugs where we accessed len for sparse arrays leading to some buggy behavior. Added a virtual length() method to ArrayData to query the highes used index in the Array.

* Avoid side effects when en exception has been thrown.Lars Knoll2013-10-293-16/+14
| | | | | | | | | | | | | | We don't want to check for exceptions after every single line on our runtime methods. A better way to handle this is to add the check in all methods that have direct side effects (as e.g. writing to a property of the JS stack). We also need to return whereever we throw an exception. To simplify the code, ExecutionContext::throwXxx methods now return a ReturnedValue (always undefined) for convenience.

* Change exception handling APISimon Hausmann2013-10-021-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
