* Tooling: Fix integer range checksUlf Hermann2018-06-061-7/+3
| | | | | | | | | | | | | | | | | The packet protocol should check if the number of bytes to be read is positive. Also, a Q_ASSERT on the return value of read() is too brutal. The device can have failed for any number of reasons and we don't want to crash the application because of that. Finally, the number of bytes to be read includes the bytes read to determine the number. Make that clearer by subtracting the actual count, not sizeof(qint32). The check in QQmlProfilerTypedEvent is supposed to happen before we cast the number to the more restrictive type. Furthermore, if subtype doesn't fit the range constraint, we don't have to do anything at all as the default rangeType is already set before.

* V4 debugger: Allow retrieval of non-CallContext scopesUlf Hermann2018-05-232-25/+23
| | | | | | | | | | | | | | We need to encode the scope type properly and we need to return something from the "scope" command. Previously the client didn't even get notified about QML contexts and couldn't actually retrieve anything but call context. The other scope types are not terribly interesting right now, but at least for the global context it should be possible to provide more data in the future.

* Make QPacketProtocol independent of QmlUlf Hermann2018-04-2315-24/+44
| | | | | | | | | | Just because we need a data stream version for QQmlDebugPacket, we don't need to add such a huge dependency. Using a template here adds some boiler plate to all users of QQmlDebugPacket, but this is worth it.

* QML Tooling: Don't send StartTrace if we haven't started any profilersUlf Hermann2018-03-271-2/+1
| | | | | | | | | | If the client requested the trace to be started before any engines were registered, this would result in a StartTrace with an empty list of engines, which would never be matched by an EndTrace. This is rather confusing. It's better to send nothing at all. Change-Id: I8728628bd7c9fe068f7275c499440f95542dcc11 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

* Fix crash with the software renderer and windows with QObject parentSimon Hausmann2018-02-152-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a QQuickWindow is a child of another QObject (such as a Loader) and is scheduled for deletion using a deferred delete event, then a deletion via the parent ends up calling the window's destructor, which will finally end up in ~QObject(), which takes care of removing the posted deferred deletion event from the event queue. In the case of QQuickWindow, the destructor - called before ~QObject - calls windowDestroyed(this) on the SG render loop. The implementation in the software renderer calls QCoreApplication::sendPostedEvents() with QEvent::DeferedDelete, which ends up deleting the same window a second time and resulting in a crash. I can't see a good reason for the existence of the sendPostedEvents() call there. It is not present in the other render loops and according to git blame it stems from the very early first implementation of the software renderer where surely copy & paste from other render loop code was involved back then. The same fix is applied to the single-threaded VG and D3D12 render loops, as they are most likely copy & paste from the software render loop implementation.

| * | | | Re-enable Debug instructions and locations for QML functionsUlf Hermann2017-11-063-1/+3

We also need to insert Debug instructions before Ret, so that we can step out. We also need to assign line numbers to the entry and return points of "abbreviated" QML functions (by simulating lbrace and rbrace) so that we can set break points on them. The line numbers on Ret need to be negative, so that you cannot (accidentally) set break points on them. A typical signal handler or binding in QML consists of only one line and if you set a break point on that line, you want it to hit only once, when entering the function. If the line numbers on Ret were positive, it would be hit again on exit. Some of the tests in tst_qqmldebugjs implicitly check for that. Also the new interpreter does something on the left brace, so a function actually starts there, not on the first statement.

Instead, these instructions not return the old context, that is then stored in a temporary. Get rid of Engine::current and Engine::currentContext. The StackFrame structures do now contain the only and authoritive data. This finally gives us a nice setup where we create and destroy frames on the stack when entering/leaving functions.
