* Avoid side effects when en exception has been thrown.Lars Knoll2013-10-291-4/+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 Hausmann2013-10-021-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
