* Fix Managed::as<>() methodLars Knoll2014-07-221-6/+6
| | | | | | | | | | | | | | | The as<> casting method was not doing the right thing in 100% of the cases. It only checked if the object in question was exactly of the type being asked for. It however didn't check if the object was derived from the type. This commit fixes this by adding a parent chain to the vtables, that is then being used to check this safely at runtime.

* Fix XHR auto tests always failingSimon Hausmann2014-04-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | The test (rightly so) expects that even for a 400 response, the responseBody must be preserved - as per commit 0949071f13e7bcbc16a0f07f496e0b6a23b04edd. However before commit fd5dd2712656cbc674c8360754394e41dd82e40c in qtbase, 400 was mapped to QNetworkReply::UnknownContentError, which is "handled" by QQmlXMLHttpRequest::error in the sense that the body is preserved. After the qtbase behavioral change, 400 now maps to QNetworkReply::ProtocolInvalidOperationError, which was _not_ handled, the body was cleared and the test failed. The revdep of qtdeclarative for qtbase should've caught the behavioral change in qtbase, but unfortunately the auto-test was disabled (marked insignificant). This patch adjusts the xhr implementation to the behavioral change in qtbase and also re-activates the xhr auto-test (we really should be testing our xhr implementation in the CI system...).

* Avoid side effects when en exception has been thrown.Lars Knoll2013-10-291-18/+24
| | | | | | | | | | | | | | 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 Hausmann2013-10-021-12/+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.
