* QSlotObjectBase: combat virtual function "bloat"Marc Mutz2012-08-151-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In C++, the compiler creates extra functions and data for classes with virtual functions. This can lead to "virtual function bloat": http://www.boost.org/doc/libs/1_47_0/doc/html/function/misc.html#id1382504 This is especially true when the number of instances is of the same order of magnitute as the number of derived classes, such as is common with type erasure techniques. One such case is the QSlotObjectBase hierarchy, which this patch tackles. The mechanics of this optimisation are simple: re-implement the virtual function call mechanism by hand, with function pointers. But we go one step further and collapse the vtable into a single pointer to a function that implements all three currently-defined operations, swtching on an 'int which' argument. This even allows us to extend this in a BC way, should that become necessary later, by adding a new Operation and using the void** argument to transport arguments, if any. This approach was inspired by: Ulrich Drepper: How To Write Shared Libraries, Section 2.4.4 http://www.akkadia.org/drepper/dsohowto.pdf Also move the QSlotObjectBase hierarchy out of QObject so as not to export all the derived classes.

* Call QObject::disconnectNotify() when receiver is destroyedKent Hansen2012-06-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Store the signal index in QObjectPrivate::Connection, thereby making it available in "implicit" disconnect contexts (i.e., receiver deletion). This change does not cause the size of QObjectPrivate::Connection to grow (still 40 bytes on 32-bit Linux, 72 bytes on 64-bit Mac). Valgrinding the new benchmark indicates that the percentage of the time spent in the QObject destructor increased from 7.8% to 8.4% on ia32, for that particular stress test; the increase is the combined cost of calling metaObject(), QMetaObjectPrivate::signal(), and disconnectNotify() for one connection. In practice, the measured wallclock time increased by about 3ms for a 500ms run (which repeatedly constructs, connects, and destroys an object).

* Add QMetaMethod-based QObject::connect/disconnectNotify() APIKent Hansen2012-05-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This API will fully replace the const char *-based connectNotify() and disconnectNotify() in Qt5; the old functions will be REMOVED before Qt 5.0 final. The new implementation fixes the long-standing issue of connectNotify() not being called when using the (internal) index-based QMetaObject::connect() (e.g., from QML). As with the old API, there are still two "unintuitive" behaviors concerning disconnectNotify(): - disconnectNotify() is not called when the signal is disconnected using the QObject::disconnect(QMetaObject::Connection) overload. - disconnectNotify() is not called when a receiver is destroyed (i.e., when a connection is implicitly removed). The old versions of connectNotify() and disconnectNotify() are kept for now, and they are still called. They will be removed once known existing reimplementations (e.g., QtNetwork, QtDBus) have been ported to the new API.

* Don't release timer ids in event dispatcher codeBradley T. Hughes2012-01-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 3rdparty event dispatchers are impossible to write without using the internal API QAbstractEventDispatcherPrivate::releaseTimerId(). Fix this by having each QObject keep track of its own timer ids, and release them when they are no longer used. As a side effect, this makes the QObjectData::pendTimer bit unnecessary. This also removes the QObjectData::inThreadChangeEvent hack that the event dispatchers used to avoid releasing timer ids when moving timers to a new thread. QBasicTimer becomes even more low-level. It cannot use QObject::startTimer() anymore, since we do not have a way to call QObject::killTimer() from QBasicTimer::stop(). QBasicTimer uses the QAbstractEventDispatcher interface directly, and releases the timer id explicitly as well when stopping the timer. This change also fixes some rare timer id "leaks" when destroying or stopping timers after a thread has exited and destroyed its event dispatcher (the timer ids would never be released when no dispatcher exists). Globally destructed QObjects that have running timers may try to release their timer ids after the timer id freelist has been destroyed. This commit accomodates such objects by avoiding the null dereference in QAbstractEventDispatcherPrivate::releaseTimerId().

* Remove QMetaObject guards and deprecate QPointer.Bradley T. Hughes2011-12-101-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | QWeakPointer is superior and preferred. Remove QMetaObject::addGuard(), QMetaObject::changeGuard(), QMetaObject::removeGuard(), and QObjectPrivate::clearGuards(). Implement QPointer using QWeakPointer<T> instead. This changes the behavior of QPointer in 2 ways: - During destruction of a QWidget. Previously, the destructor of QWidget would reset all QPointers so that they would return zero when destroying children. Update tst_QPointer to account for this change. - When constructing a QSharedPointer to take ownership of an object after a QPointer is already tracking the object. Previously, the shared pointer construction would not be affected by the QPointer, but now that QPointer is implemented using QWeakPoiner, constructing the QSharedPointer will cause an abort(). Fix tst_QSharedPointer by removing the use of QPointer in the objectCast() test. These behavior changes are documented in the QPointer class documentation and in the changes file.

* New QObject connection syntaxOlivier Goffart2011-11-251-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In addition to the old connection syntax, you can now connect using function pointers. connect(sender, &Sender::valueChanged, receiver, &Receiver::updateValue ); You can connect also to functor or C++11 lambdas The connections are now type safe (no more problems with namespaces or typedefs). Implicit type conversion is also supported. The new syntax forces us to change the meaning of signal form protected to public, in order to be able to access the signal's address everywhere The way it works is by introducing new overload of QObject::connect that take function pointer as parametter. Those new overload are template function, that are implemented inline. The actual implementation is in QObject::connectImpl which take a QObject::QSlotObject* as parametter for the slot. That slot object contains a virtual function which call the slot which has to be implemented in the header as it depends on the template parametter. So the internals of QObjectPrivate::Connection will store this QObjectSlot* in order to be able to make the call.

QObjectPrivate::Connection is now reference counted. tst_qglobal.cpp: This test set up an internal callback, and the callback do not set any proper connection handle (and tbh, it would be hard for it to do so). So the returned QMetaObject::Connection is invalid, and ok is false (Internal callbacks are only used for jambi and should probably be removed) Change-Id: I111626fb4f47efc4db5e2ea5bff9da15f08fea7b Reviewed-by: Bradley T.
