* use JSObject::inherits() instead of JSObject::isObject()Kent Hansen2009-09-211-3/+3
| | | | | | The functions are identical, but in recent WebKit trunk isObject() doesn't exist anymore. So this renaming is done to prepare for the import of a more recent JavaScriptCore.

* Fix the bactkrace in the QScript DebuggerOlivier Goffart2009-09-091-6/+1
| | | | | | | | | | | | | | | | | | This patch remove the 'fake' context that appears in the debugger backtrace when there is a break point in the global context. This problem never appeared in the tests because the QScriptContext::backtrace has always at least two items in the backtrace as it needs the native 'bt' function to be called. Changed QScriptEnginePrivate::contextForFrame to skip the fake frame (instead of QScriptContext::parentContext). So we never have a QScriptContext pointing to that frame. The changes in QScriptContextInfo are for retreiving the right filename information for the global context when the global context is on top. Reviewed-by: Kent Hansen

* push the right object when the argument is the Global ObjectKent Hansen2009-08-141-4/+13
| | | | | | | | | Since the internal Global Object is never exposed to the public, we need to do like we do in setActivationObject(): if the object passed is the Global Object proxy, use the internal Global Object as the "real" argument. (JSC requires that the initial object pushed onto the scope chain is an instance of JSC::JSGlobalObject, and the Global Object proxy is not; hence, we can't push the proxy.)

* make sure QScriptContext::scopeChain() returns the right objectKent Hansen2009-08-141-2/+9
| | | | | | | | Follow-up to commit e0a86dc604b87921652b844a5f85889bb6291ed9. Just like in the activationObject() function, we need to check if the activation object is actually a proxy to another object, and return that other object if that's the case (the proxy object should not be exposed to the public).
* make it possible for any script object to serve as activation objectKent Hansen2009-08-141-6/+23
| | | | | | | This was possible in the old back-end. In JSC, activation objects have to be instances of JSC::JSVariableObject. So the way we solve it is by having our QScriptActivationObject be able to act as a proxy to any other JSObject.
* Fix compilation on WindowsSimon Hausmann2009-08-141-0/+1

* Lazily construct the QScriptActivationObjectOlivier Goffart2009-08-131-23/+36
| | | | | | | | | | | We can store flags on the ReturnValueRegister entry in the stackframe header (as native function don't use that) Then when requesting an activation object we can lookup the flags to know if we should create it. This reduce a lot the cost of a native call. Reviewed-by: Kent Hansen

* make it possible to pop all items in a scope chain and then push to itKent Hansen2009-08-111-8/+24
| | | | | | | | | | | | | A lot of the JSC::ExecState functions rely on scopeChain() not being 0. This means we shouldn't pop the scope chain if doing so would make it empty; otherwise when you call e.g. pushScope() or evaluate(), you will crash. So instead of popping the chain completely, we now set the sole scope chain item's object pointer to 0 and add appropriate checks elsewhere. A second issue, not solved in this commit, is that JSC expects the Global Object to always be the last item in every scope chain. If it's not, you will crash.
* Fix line number and arguments in QScriptContext::toStringOlivier Goffart2009-08-111-5/+2
| | | | | | | | | | | | For arguments, we always need to skip the implicit 'this' argument For line number, we walk thought the stack frames from the top to find the one above the requested one, which contains the returnPC we need.

* add configure options for (not) building the QtScript moduleKent Hansen2009-08-071-4/+0
| | | | | | | | | | | | | | | | | | -script (default) and -no-script. This means we can get rid of the SCRIPT feature from qfeatures, since it's now handled by the new configure variable. It also allows us to get rid of all the QT_NO_SCRIPT ifdefs from the source files, since qmake isn't going to include those files for compilation when you configure with -no-script. The QtScriptTools module will be disabled if the QtScript module is not built. You'll have to build the old QtScript back-end (will be made available in a separate package), then build the QtScriptTools module yourself. Reviewed-by: Simon Hausmann
