* | Port to the new QUrl APIThiago Macieira2012-03-301-23/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The use of any broken-down components of the query now needs QUrlQuery. The QUrl constructor and toString() are now rehabilitated and the preferred forms. Use toEncoded() and fromEncoded() now only when we need to store data in a QByteArray or the data comes from a QByteArray anyway. Change to toString() or the constructor if the data was in a QString.

| | | | | | | | | | | | | | | | | | | | | | | | The code was only allocating memory for the next insertion leading to a reallocation of the whole data for every single insertion.

* | Rewrite QMap to use a RB treeLars Knoll2012-03-233-0/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QMap used to use a skiplist in Qt 4.x, which has variable sized nodes and we can thus not optimise using custom allocators. The rewrite now uses a red-black tree, and all allocations and tree operations happen in the cpp file. This will allow us to introduce custom allocation schemes in later versions of Qt. Added some more tests and a benchmark. Memory consumption of the new QMap implementation is pretty much the same as before. Performance of insertion and lookup has increased by 10-30%. iteration is slower, but still extremely fast and should not matter compared to the work usually done when iterating.

* | Rename QMetaMethod::signature() to methodSignature()Kent Hansen2012-02-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

| * Drop file-engine abstraction from public APIJoão Abecasis2012-02-222-5/+43

In particular, by allowing file names to be arbitrarily hijacked by different file engines, and requiring engines to be instantiated in order to decide, it imposed unnecessary overhead on all file operations. Another flaw in the design with direct impact on performance is how engines have no way to provide (or retain) additional information obtained when querying the filesystem. In many places this has meant repeated operations on the file system, where useful information is immediately discarded to be queried again subsequently. For Qt 4.8 a major refactoring of the code base took place to allow bypassing the file-engine abstraction in select places, with considerable performance gains observed. In Qt 5 it is expected we'll be able to take this further, reaping even more benefits, but the abstraction has to go. [Dropping this now does not preclude that virtual file systems make an appearance in Qt at a later point in Qt 5's lifecycle. Hopefully with a new and improved abstraction.] Forward declarations for QFileExtension(Result) were dropped, as the classes were never used or defined. Tests using "internalized" classes will only fully run on developer builds. QFSFileEngine was removed altogether from exception safety test, as it isn't its intent to test internal API.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently QMetaType API contains almost only static methods. This works nice until someone needs more information or needs to do more operations on a type. In this case every function call has to do type dispatch. This API allows to avoid redundant type dispatching, by caching a type information in a QMetaType instance. It gives significant performance boost especially for custom types (up to 9x).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This includes padding necessary to align the data array, but excludes the first element as was done before. Size of header is the interesting piece of information, anyway. This simplifies calculations in a couple of places, harmonizes code with the QRawVector fork and paves the way for further changes in QVector, namely the memory layout. When Q_ALIGNOF is not available, default to pointer-size alignment. This should be honoured by malloc and won't trigger use of more expensive aligned allocation.
