* Encapsulate the current context and fix it's usageLars Knoll2013-12-043-16/+16
| | | | | | | | | | | Encapsulate accesses to the current context, and rework the way we push and pop this context from the context stack. Largely a cleanup, but simplifies the code in the long term Change-Id: I409e378490d0ab027be6a4c01a4031b2ea35c51d Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Fixup the implementation mess for QJSValue(QString)Lars Knoll2013-12-043-10/+111
| | | | | | | | | | | | | | | Until now we were using a QV4::String without engine to represent this case. But this leads to lots of quirks, where we ended up trying to access the engine (or the internalclass/vtable) of this string anyway. Now just represent it by using an QString in QJSValuePrivate, and use an empty value to represent it. This adds a little bit of code to QJSValue and QJSEngine, but is more stable and maintainable in the longer term.

| | | | | | | | | | The code in the Exception class operates entirely on the engine's data, so move it into ExecutionEngine instead.

* Change exception handling APISimon Hausmann2013-10-023-32/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
