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.

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

The dual codepaths have been replaced by asserts that indicate the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

Hence, too old meta-objects will be caught at compile time, and the

Qt5's moc on the original class declaration).

This commit introduces two significant changes to the meta-object
data format:
1) Meta-type information (QMetaType type/name) information is
stored directly in the meta-data for both properties and methods;
2) The original signature (string) of a method is no longer stored
in the meta-data, since it can be reconstructed from the method
name and parameter type info.
The motivation for this change is to enable direct access to method
names and type information (avoiding string-based lookup for types
if possible), since that's typically the information language
bindings (e.g. QML) need. (moc already had all the desired
information about methods, but it threw it away!)
This change keeps support for the older (6 and below) meta-object
revisions, but the support will be removed after a short grace
period.
The following public QMetaMethod functions have been added:
name() : QByteArray
returnType() : int
parameterCount() : int
parameterType(int index) : int
The following internal QMetaMethod function has been added:
getParameterTypes(int *types) : void
This commit extends the meta-method data to include explicit
type/name data for methods. The new data follows the existing
(5-word) method descriptors in the meta-data. The method descriptor
format was modified to enable this. First, the descriptor now
contains the meta-data index where the method's type/name information
can be found. Second, the descriptor contains the number of
parameters. Third, the descriptor has a reference to the name of the
method, not the full signature.
Each entry of a method's type/name array contains either the type id
(if it could be determined at meta-object definition time), or a
reference to the name of the type (so that the type id can be
resolved at runtime).
Lastly, instead of storing the method parameter names as a
comma-separated list that needs to be parsed at runtime (which was
how it was done prior to this commit), the names are now stored as
separate entries in the meta-object string table, and their indexes
are stored immediately after the method type info array. Hence,
parameter names can be queried through the public API without
parsing/allocating/copying, too.

Up to and including meta-object revision 6, string data have been

accessible as const char pointers through the public API
(QMetaMethod and friends).
This commit changes moc to generate an array of QByteArrayData
instead, and adapts the QObject kernel accordingly.
Generating an array of QByteArrayData (byte array literals)
means that the strings can now be returned from public (or private)
API as QByteArrays, rather than const char *, with zero allocation or
copying. Also, the string length is now computed at compile time
(it's part of the QByteArrayData).
This commit only changes the internal representation, and does
not affect existing public API. The actual (C) string data that the
byte array literals reference still consists of zero-terminated
strings. The benefit of having the QByteArrayData array will only
become apparent in the upcoming meta-object data format change, which
changes the format of property and method descriptors.
Support for the old meta-object string data format was kept; the
codepaths for old revisions (6 and below) will be removed in a
separate commit, once all the other meta-object changes are done and
affected code has been adapted accordingly.

QBasicTimer becomes even more low-level. It cannot use
QObject::startTimer() anymore, since we do not have a way to call

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

The connections are now type safe (no more problems with namespaces

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.

Q_WS_QPA is the only active code path after merging
refactor, other Q_WS-macros are no longer used.
Enable compilation without -qpa.
- Remove Q_OS_MSDOS, Q_OS_OS2
- Remove Q_WS_QWS
- Remove/replace definitions/conditionals of Q_WS_XX
- Remove qpa branches from profiles
- Replace Q_WS_MAC by Q_OS_MAC

create() is symmetric with destroy().
Also rename the internal methods and fields to be
consistent (qDeleteHelper already had the "right"
name, though!).
This change will allow us to use construct() and
destruct() for something else: Placement new-style
allocation (QTBUG-12574).
The old construct() is still kept for now, until
the other repositories have been updated to use
create().

Most of these changes are search-and-replace of d->ref ==, d->ref !=

The QBasicAtomicPointer in QObjectPrivate::Connection didn't need to
be basic, so I made it QAtomicPointer.

For property notify signals, QtDeclarative can manage connections
in a more special case - and more performant - way. This patch
adds a callback hook so that QtDeclarative can intercept signals
being emitted by declarative objects.

Since we now have QBasicMutex as a POD, we can simplify the mutexpool.
This remove the call the the Q_GLOBAL_STATIC and some others tests that
are taking CPU cycles when activating a signal.
The QMutexPool class itself can't be simplified because its mutex are
recursive mutexes, and the size is dynamic. also it is harder to get all
the mutexes initialized to 0.

The d pointer is not anymore always a QMutexPrivate.
If d == 0x0: the mutex is unlocked
If d == 0x1: the mutex is locked, uncontended
On linux:
if d == 0x3: the mutex is locked contended, waiting on a futex
If d is a pointer, it is a recursive mutex.

This has two direct benefits:
1) compiles regardless of -fno-exceptions: no need for #ifndef
QT_NO_EXCEPTIONS or QT_TRY/QT_CATCH
2) no QT_RETHROW either, which means the backtrace of an application
crashing due to an uncaught exception will include the actual throw
point.

Some functions (such as QObject::moveToThread) did not keep
the event ordered by priority.
And because qUpperBound is used to add events, that mean new
events would not be inserted in order.
