* Introduce QMetaType::UnknownType.Jędrzej Nowacki2012-03-021-9/+11
| | | | | | | | | | | | | | | | | 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(); Change-Id: I73ff097f75585a95e12df74d50c6f3141153e771 Reviewed-by: Kent Hansen <kent.hansen@nokia.com> Reviewed-by: Olivier Goffart <ogoffart@woboq.com>
* Long live Qt5 meta-object method/property descriptorsKent Hansen2012-02-291-60/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Change the representation of meta-object string dataKent Hansen2012-02-291-72/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* moc: Only generate IndexOfMethod for signals.Olivier Goffart2012-02-281-4/+8
| | | | | | | | | | | | | | | | | | | | 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. Change-Id: Ia417e3e524d7915ca86433ea86c66ac2b299c81a Reviewed-by: Kent Hansen <kent.hansen@nokia.com>

* Bring qmetaobjectbuilder in sync with mocKent Hansen2012-02-031-1/+1
| | | | | | | | | | | | | | | | | | | 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.

* moc: Use QMetaType::QVariant as the type for QVariantKent Hansen2012-01-251-2/+0
| | | | | | | | | | | | | | | | | | | 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.

* Remove the Q_NO_DATA_RELOCATION hackOlivier Goffart2012-01-131-13/+0
| | | | | | | | | | | | | | 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.
