* QMetaMethod::invoke: compare the QMetaType id of the return typesOlivier Goffart2013-08-291-2/+7
| | | | | | | | | | | | | | | | | | | | | | Since Qt5, the QMetaObject do not contains the string name of the builtin types, but only the QMetaType id. QMetaMethod::typeName convert back from the id to the string. But if the type is aliased, the string of the main type is returned. This was the case for example for qint64 which is transformed to "qlonglong". This causes a regression in QMetaType::invoke when trying to invoke a method which return an aliased type, since the string comparison would fail. Fix the problem by also comparing the metatype id.

* Add private API for working with meta-methods in signal index rangeKent Hansen2012-06-011-16/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix regression in connectNotify(const char *) emissionKent Hansen2012-05-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

* Clean up constructors for "statics" in QString and QByteArrayJoão Abecasis2012-04-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Change-Id: I9b92fbaae726ab9807837e83d0d19812bf7db5ab Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Remove support for meta-object revisions < 7Kent Hansen2012-03-221-297/+67
| | | | | | | | | | | | | | | | | | | | | | | | | 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).

* QMetaMethod::typeName() should return "void" if the return type is voidKent Hansen2012-03-211-10/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QMetaType::Void was ambiguous, it was pointing to a valid type (void) and in the same time it was signaling errors in QMetaType.

So it will be easy to distinguish between: void mySlot(); MyUnregisteredType mySlot(); Change-Id: I73ff097f75585a95e12df74d50c6f3141153e771 Reviewed-by: Kent Hansen <kent.hansen@nokia.com> Reviewed-by: Olivier Goffart <ogoffart@woboq.com>

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.

* | Rename QMetaMethod::signature() to methodSignature()Kent Hansen2012-02-291-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* | Change the representation of meta-object string dataKent Hansen2012-02-291-38/+76
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
