The test was assuming that "data()" is a special function in autotests,
but that hasn't been the case since early prototypes of testlib.

15c13b91e6 Add Q_IS_ENUM(), and provide as flag in QMetaType::typeFlags()
Add Q_IS_ENUM() macro to determine if a given type is an
enumeration. Use information from that in QMetaType::registerType()
to store whether custom registered metatypes are enums or not.
This information can then be accessed by calling
QMetaType::typeFlags(int type). This is used by the declarative
code to determine whether a custom type in a variant can be safely
cast to an integer, which is required to allow passing non-local
enums as signal/slot params.

eb24dfcccb Add template specialization of QMetaType for QObject derived pointers.
This makes it possible to do things like

QVariant::fromValue(new SomeObject);

without first using Q_DECLARE_METATYPE(Something*)

This functionality was originally part of
http://codereview.qt-project.org/#change,11710 but was rejected
because the functionality was based on specialization of
QVariant::fromValue which could be dangerous.

This new implementation doesn't have such danger.

362bde8e8e Introduce QMetaType::UnknownType.
QMetaType::Void was ambiguous, it was pointing to a valid type (void)
and in the same time it was signaling errors in QMetaType. There was
no clean way to check if returned type was valid void or some
unregistered type.

This feature will be used by new QMetaObject revision which will
store type ids instead of type names. So it will be easy to
distinguish between:
 void mySlot();
 MyUnregisteredType mySlot();

f95181c7bb Long live Qt5 meta-object method/property descriptors
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.

96f2365cf4 Rename QMetaMethod::signature() to methodSignature()
In Qt5 the meta-data format will be changed to not store the
method signature string explicitly; the signature will be
reconstructed on demand from the method name and parameter type
information.

The QMetaMethod::signature() method returns a const char pointer.
Changing the return type to QByteArray can lead to silent bugs due to
the implicit conversion to char *. Even though it's a source-
incompatible change, it's therefore better to introduce a new
function, methodSignature(), and remove the old signature().

3f7a222414 Change the representation of meta-object string data
Up to and including meta-object revision 6, string data have been
stored as 0-terminated C-style strings, that were made directly
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.

0d9714f445 moc: Only generate IndexOfMethod for signals.
moc is currently generating code to convert from a pointer to member
function of a slot or signal to its index.

The idea was that it could be usefull for slots to have the new syntax
do the same as the old one (connecting signal index to slot index). But
in practice, the new syntax do not use the IndexOfMethod for slots.

Also, it does not work for all the slots (no Q_PRIVATE_SLOT,
no static slots)

So since it is not used, and that it would take room in the binaries to
generate all the code to get the index of slots, we remove it.

If ever we need it, we can still add it later.

nice until someone needs more information or needs to do more operations

This API allows to avoid redundant type dispatching, by caching a

performance boost especially for custom types (up to 9x).

3f74aea9bb Fix tst_QSocketNotifier on Mac OS X
Socket notifier behavior is very OS-dependent. QtNetwork uses non-
immediately (it will return -1 w/ errno=EINPROGRESS). We have to wait
with select(2) to indicate that the connection is ready, then call
connect(2) again. When this happens, we need another call to select(2)
to get notification on the listening socket so that we can call
accept(2) to complete the connection.

The mixingWithTimers() failure happens due to the test expecting a
single processEvents() call to be able to completely connect a TCP
socket. But as described above, this may not happen. The test should
QTRY_COMPARE() to give the test a chance to let all this happen.

The posixSockets() test can fail due to the same connect() behavior. The
test already has a comment about the write notifier behavior being very
OS dependent. This caused the first enterLoop() to return too early,
before the read notifier fired (which is what the test is checking for,
that the read notifier fired). Move creation of the write notifier to
where we expect it to fire, just before writing to the posix socket.

In the same test, the read notifier inside QTcpSocket may not fire after
the write notifier on the posix socket. Use the waitForReadyRead()
function to give the socket a chance to read the data written to the
posix socket.

allowing the test to pass, while clang evaluates the arguments in order
from left to right, causing the test to fail.

ae85d7c965 Treat pointers to QObject derived types in QVariant specially.
It is possible to do this for example:

QVariant v = QVariant::fromValue<MyCustomQObject*>();
QObject *object = v.value<QObject*>();

This means that if a QVariant contains a pointer to a QObject
derived type, third parties can extract a QObject* and use its
properties without knowing the concrete type.

This is a source compatible change.

5a92dd6124 Detect incompatibilities in repeated type registration
QMetaType used to register a typeName and factory functions for
creation/destruction of objects. While it would be possible for a single
type name to be registered matching different actual types and memory
layouts, there was little that could be done about it.

Now that QMetaType is tracking type information with a direct impact on
data layout and ABI (size and type flags) it is important that we check
and detect binary incompatibilities as early as possible.

[Such incompatibilities could arise from type name re-use (technically,
ODR violations) or, more commonly, as version mismatch between different
shared libraries or plugins.]

Only type size and flags are checked as function pointers to inline and
template or otherwise non-exported functions could trivially differ
across translation units and shared libraries.

When registering typedef types, a check is made to ensure the same name
doesn't get registered as different types.

b8cf1d6bdc Remove QMetaType::unregisterType().
The function hasn't been working properly. It was not well tested, for
example it is undefined how QVariant should behave if it contains an
instance of an unregistered type.

Concept of unregistering types was inspired by plug-in system, but in
most supported platforms we do not unload plug-ins.

Idea of type unregistering may block optimizations in meta object
system, because it would be not possible to cache a type id.
QMetaType::type() could return different ids for the same name.

Currently QMetaType::unregisterType() is not used in Qt.

56265031b7 Align QVariant::UserType and QMetaType::User
There is no point in keeping separate values which should mean the
same.

QVariant::UserType was used also to construct a valid, null QVariant,
containing an instance of unknown custom type. The concept was strange
and useless as there was no operation that could be done on such
QVariant. Therefore it was dropped.

Please note that the patch slightly changes behavior of different
functions accepting a type id as parameter. Before QVariant::UserType
was an invalid type from QMetaType perspective (id 127 was not assigned
to any built-in type), but QMetaType::User points to the first registered
custom type.

b184dd0a01 Bring qmetaobjectbuilder in sync with moc
qmetaobjectbuilder should generate meta-objects of the same version
as moc; in the future, when the moc version is bumped, QMOB has to
be adapted at the same time.

QMOB was generating version 4 meta-objects. This patch makes it
generate version 6 (the current version). This also fixes a bug with
using qt_static_metacall with QMOB (setStaticMetacallFunction()); it
was already using the version 6 qt_static_metacall signature, which
isn't compatible with version 4.

Also add tests that ensure that the QMOB-generated meta-object works
with real objects; in particular we want to test the codepaths in Qt
that check for version >= 4.

is added to both QEventLoop and QCoreApplication.

This allows, for example, an event loop to quit() when there is
no more work for it to do.

quitOnLastWindowClosed is implemented in terms of the refcount in
QCoreApplication so that jobs can be completed before the
application quits.

2bf186a2e5 Allow function types to be registered without workarounds
Commit 4b8ceb41ae added the requirement
that pointed-to types need to be registered when registering pointer
types. Unfortunately, the implementation also affects function pointer
types.

This change whitelists 0, 1, 2 and 3 argument functions as not deriving
from QObject, forgoing the need to workaround details of the type
registration implementation when registering those function pointer
types.
