* Updated JavaScriptCore from /home/khansen/dev/qtwebkit to ↵Kent Hansen2009-10-051-1/+1
| | | | | | jsc-for-qtscript-4.6-staging-05102009 ( 38c2b17366f24220d9ae0456a7cfe2ac78a9f91c ) Adapt src/script to src/3rdparty/javascriptcore changes
* Reset timeout-checker before evaluating when processEventsInterval is usedKent Hansen2009-10-011-0/+2
| | | | | | | | | | | | | | | | When the timeout-checker was not reset, it could take a while (e.g. 1-2 seconds) before the next timeout occurred, depending on what the tick counter happened to be after the previous evaluate(). When a processEventsInterval of e.g. 100 milliseconds has been specified, we want the timeout to happen much sooner, thus we need to reset the checker. This will cause the first timeout to happen quickly, and then at steady intervals (processEventsInterval ms) after that. The tst_QScriptEngine::processEventsWhileRunning() test was sporadically failing due to this issue. Reviewed-by: Olivier Goffart
* Fix column number provided to QScriptEngineAgentKent Hansen2009-10-011-64/+3
| | | | | | | | Introduced a helper function in our custom source provider, columnNumberFromOffset(), that maps an absolute offset in the source input to a relative column number. Reviewed-by: Jedrzej Nowacki

* QScript: fix the way the js stack is advanced.Olivier Goffart2009-09-291-4/+2
| | | | | | | | | It is possible to call QScriptEngine::pushContext before we start any evaluation. We need to change JSC so it doesn't always start at the beginning of the stack. Also fix QScriptContext::pushContext not to waste space between callframes. Reviewed-by: Kent Hansen
* QScript: Fix strange bugs and crashes.Olivier Goffart2009-09-281-7/+10
| | | | | | | | | | I was assuming that the default return value register was always set to 0 for native calls. But this is not the case. So we must ensure this. Also be consistend in the way the stackframe grow and shrink. This expose another bug in the way the call frame is created in JSC Reviewed-by: Kent Hansen

* make sure the engine's currentFrame is in sync when calling out to public APIKent Hansen2009-09-221-0/+2
| | | | | | | The currentFrame pointer is used e.g. by QScriptValue::toString(). It needs to be in sync, otherwise we will crash. Reviewed-by: Olivier Goffart
* use JSObject::inherits() instead of JSObject::isObject()Kent Hansen2009-09-211-2/+2
| | | | | | 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.
* initialize the this-register of the global contextKent Hansen2009-09-181-0/+1
| | | | | | | | | | | QScriptEnginePrivate::thisForContext() relies on the this-register of the global context to contain an invalid JSValue. The default Register constructor (used to initialize the registers of the global context) only invalidates its value when NDEBUG is not defined (but we define it). Therefore, we must explicitly set the this-register to an invalid value. Reviewed-by: Olivier Goffart

* Fix compilation with winscwSimon Hausmann2009-09-101-1/+1
| | | | | | | | Winscw gets very confused when the name of an enum value is the same as the name of an entire namespace, JSC in this case. Renaming the enum value to JavaScriptCore fixes this. Rubber-stamped-by: Kent
* Fix the bactkrace in the QScript DebuggerOlivier Goffart2009-09-091-0/+5
| | | | | | | | | | | | | | | | | | 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

* handle memory management of QScriptValuePrivate in engine if possibleKent Hansen2009-08-241-2/+23
| | | | | | | | | Avoid calling malloc() and free() so often. The premise is that QScriptValue is usually a short-lived type, and only a few QScriptValues exist at a time, so if we cache privates in the engine, QScriptValues will be much faster to create and destroy. Reviewed-by: Olivier Goffart
