* QSlotObjectBase: combat virtual function "bloat"Marc Mutz2012-08-151-18/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This was pointed out in review by Thiago.

* Call QObject::disconnectNotify() when receiver is destroyedKent Hansen2012-06-281-0/+4
| | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Remove support for meta-object revisions < 7Kent Hansen2012-03-221-136/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For Qt5 we no longer want to support the older revisions due to the dual codepaths that must be maintained, and because the format of the meta-object data is quite different in revision 7. The dual codepaths have been replaced by asserts that indicate the revision in which the feature was introduced, and the older-revision fallbacks have been removed. It's not possible to build code generated by moc that has revision <= 6 with Qt5 because the type of the QMetaObject::stringdata member changed from const char * to const QByteArrayData *. For the same reason it's not possible to build a dynamic meta-object generator targeting revision <= 6 with Qt5. Hence, too old meta-objects will be caught at compile time, and the code will have to be ported to generate revision 7 (e.g., by running Qt5's moc on the original class declaration).
