Stephen Kelly 62c2061a50 Add automatic metatype registration for Q_PROPERTY types.
In Qt 4, the user needs to call qRegisterMetaType if the property
could otherwise be read before the type is registered with the metatype
system. This patch makes that unnecessary and automatic by registering
it when the first read indicates that it is not yet registered instead
or when QMetaProperty::userType is called before it is registered.

The types which are automatically registered exclude the built-in
types, which do not need to be registered, and include metatypes which
are automatically declared, such as pointers to QObject derived types
and containers of existing metatypes.

Kent Hansen 37db43f1c2 Add private API for working with meta-methods in signal index range
Internally, QObject and QMetaObject already leave out non-signal
methods when working with signals. This is possible because the
signals always come before other types of meta-method in the
meta-object data. Ignoring irrelevant methods is faster and can
save memory.

QMetaObject provides internal indexed-based connect() and
disconnect() functions. However, these functions currently take an
absolute method index as the signal specifier, instead of an
absolute _signal_ index. Hence, QMetaObject and friends must convert
from the method index range to the signal index range.

By providing an API that only considers signal indices, clients of
the index-based QMetaObject::connect()/disconnect() can provide the
proper signal index directly. Similarly, for the qtdeclarative
integration (QDeclarativeData hooks) the signal index can be passed
directly. This will eliminate most of the conversions back and forth
between signal index and method index, and some other redundant work
done by qtdeclarative's custom connection implementation.

There are some places where the behavior can't be changed; for
example,  QObject::senderSignalIndex() will still need to return an
index in the method range, since that function is public API.

Changing QMetaObject::connect()/disconnect() to take an index in
the signal range will be done in a separate commit; this commit is
only an enabler for porting existing usage of those functions to
the new behavior.

Kent Hansen 74c3517e6a Fix regression in connectNotify(const char *) emission
Reimplementations of connectNotify() and disconnectNotify() can
assume that the signal argument is in normalized form, but after the
introduction of the Qt5 meta-object format, it could happen that it's
not.

The problem is that the internal QArgumentType class, which attempts
to resolve a typename to a type id, was calling QMetaType::type().
QMetaType::type() falls back to trying the normalized form of the
typename if the original argument can't be resolved as a type (this
behavior isn't documented, but that's how it works). This means that
e.g. QMetaType::type("const QString &") returns QMetaType::QString.

Since QMetaObjectPrivate::indexOfMethodRelative() (more specifically,
the methodMatch() helper function) prefers to compare type ids
over typenames (since the type ids are stored directly in the meta-
object data for built-in types), the method lookup would *succeed*
for signatures with non-normalized built-in typenames as parameters.
QObject::connect() would then think that it did not have to
normalize the signature (see "// check for normalized signatures").
The consequence was that the original, non-normalized form got
passed to connectNotify().

This commit introduces an internal typename-to-type function that
is the same as QMetaType::type(), except it doesn't try to normalize
the name. This way, the only place where normalization can occur in
the signature-to-meta-method processing is through the calls to
QMetaObject::normalizedSignature() in QObject::connect() itself.

The implication is that there are now cases where the method
signature will be decoded and processed twice, where processing it
once was sufficient before. On the other hand, it is consistent with
the pre-Qt5-meta-object behavior, where we predict that the
signature is already normalized, and only perform (comparatively
costly) normalization if the initial lookup fails.

Kent Hansen 243ea09e4c Add QMetaMethod-based QObject::connect/disconnectNotify() API
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.

João Abecasis a959f34d71 Clean up constructors for "statics" in QString and QByteArray
There were two constuctors offering essentially the same functionality.
One taking the QStatic*Data<N> struct, the other what essentially
amounts to a pointer wrapper of that struct. The former was dropped and
the latter untemplatized and kept, as that is the most generic and
widely applicable. The template parameter in the wrapper was not very
useful as it essentially duplicated information that already maintained
in the struct, and there were no consistency checks to ensure they were
in sync.

In this case, using a wrapper is preferred over the use of naked
pointers both as a way to make explicit the transfer of ownership as
well as to avoid unintended conversions. By using the reference count
(even if only by calling deref() in the destructor), QByteArray and
QString must own their Data pointers.

Const qualification was dropped from the member variable in these
wrappers as it causes some compilers to emit warnings on the lack of
constructors, and because it isn't needed there.

To otherwise reduce noise, QStatic*Data<N> gained a member function to
directly access the const_cast'ed naked pointer. This plays nicely with
the above constructor. Its use also allows us to do further changes in
the QStatic*Data structs with fewer changes in remaining code. The
function has an assert on isStatic(), to ensure it is not inadvertently
used with data that requires ref-count operations.

With this change, the need for the private constructor taking a naked
Q*Data pointer is obviated and that was dropped too.

In updating QStringBuilder's QConcatenable specializations I noticed
they were broken (using data, instead of data()), so a test was added to
avoid this happening again in the future.

An unnecessary ref-count increment in QByteArray::clear was also
dropped.

Kent Hansen e1e0e83c5e Remove support for meta-object revisions < 7
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).

Kent Hansen 22d621dd99 QMetaMethod::typeName() should return "void" if the return type is void
QMetaMethod::typeName() is documented to return an empty string if
the return type is void. But after the introduction of
QMetaType::UnknownType (where void was made a distinct type),
returning an empty string causes the idiom

   QMetaType::type(method.typeName())

to break; the result will be QMetaType::UnknownType rather than
the expected QMetaType::Void for methods that return void.

New code should use the new function QMetaMethod::returnType()
instead, but it would be good if existing code still did the right
thing.

The consequence of returning "void" instead of an empty string is
that it breaks existing logic that uses the typeName() length to
determine whether a method returns void. But we judge this as the
lesser of the two evils; it's better to have a typeName() function
that is consistent and keeps the QMetaType::type(method.typeName())
idiom working, than to force the typeName() inconsistency for void
only to keep code that does "strlen(method.typeName()) == 0"
working.

The places in Qt that were relying on a zero-length typeName()
(testlib, dbus, declarative) have already been changed to use
returnType().

Also adapt QMetaObjectBuilder, which is internal API.

Kent Hansen 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,

Kent Hansen 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().

Kent Hansen 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.

This function provides a proper way of determining whether a function
returned by QMetaObject::method() is valid. (Checking whether
signature() returns a 0 pointer, which e.g. testlib does, is not an
ideal API -- especially given that signature() will soon be removed
and replaced by a function that returns a QByteArray.)

Jędrzej Nowacki 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.

Kent Hansen 00c8984b4e moc: Use QMetaType::QVariant as the type for QVariant
QMetaType::QVariant has existed as a proper type for almost two
years, but the qvariant_nameToType function was written in 2006.

Using QMetaType::QVariant means QVariant can be treated just like
any other type. We can get rid of those hacky checks for LastType,
and the remaining checks become more readable.

The fact that QMetaProperty::{type,userType}() returned LastType
(0xffffffff) for QVariants was never documented (LastType itself is
internal). But there are other Qt modules that assume so. I'll fix
the ones I know about (qtdeclarative, qtscript, activeqt).

This hack was there because symbian used to have a problem with
relocations in the data section, between libraries. Hence, this was needed
so the metaobject could have a pointer to the base metaobject, despite
being in another library.

Anyway, I was told that symbian was fixed eventually. but the hack had to
stay there because of compatibility. But now that we don't even support
symbian, we can get rid of this hack totally.

The old construct() is still kept for now, until
