* Add QMetaType::type(QByteArray) functionKent Hansen2014-10-311-6/+19
| | | | | | | | | | | | | | | | | | | QMetaType::type(const char *) requires that the string argument is 0-terminated. This new overload makes it possible to query the type of a string with an explicit length. In particular, QByteArrays constructed by QByteArray::fromRawData(), for example from a substring of a normalized method signature (the "int" part of "mySlot(int"), can now be queried without making a copy of the string. Also, Qt5 meta-objects represent type names as QByteArray literals, which can be fed directly to this new QMetaType::type() overload (no need to call strlen).

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.
