6e4d7bbb0b QMap 5.0 - keep track of leftmost node (BIC)
This suggestion keeps track of the most left node.
The point is that constBegin() becomes a lot faster.

That speeds up iteration a bit, and makes it O(1) to get the
first element. The penalty in insert and remove is very small.
On large trees it seems to be less than 1%.

It should be noticed that constBegin() is a very common hint
on my planned change to 5.1, and this opperation will without
this patch cost 2 x log N. One when the user calls the hint
with begin - and one where it is compared with begin.

Other std::maps has a very fast begin(). E.g
http://www.cplusplus.com/reference/stl/map/begin/
(begin with constant time)

We now consider all format range edges to generate the

the additionnal formats mechanism.

Adds an autotest that checks that this works with font capitalization.

51d40d7e9b Make gui/math3d classes use float rather than qreal
This corrects the mismatch between using floats for internal storage
and qreal in the API of QVector*D which leads to lots of implicit
casts between double and float.

This change also stops users from being surprised by the loss of
precision when using these classes on desktop platforms and removes
the need for the private constructors taking a dummy int as the final
argument.

The QMatrix4x4 and QQuaternion classes have been changed to use float
for their internal storage since these are meant to be used in
conjunction with the QVector*D classes. This is to prevent unexpected
loss of precision and to improve performance.

The on-disk format has also been changed from double to float thereby
reducing the storage required when streaming vectors and matrices. This
is potentially a large saving when working with complex 3D meshes etc.

This also has a significant performance improvement when passing
matrices to QOpenGLShaderProgram (and QGLShaderProgram) as we no
longer have to iterate and convert the data to floats. This is
an operation that could easily be needed many times per frame.

This change also opens the door for further optimisations of these
classes to be implemented by using SIMD intrinsics.

This needs to be applied in conjunction with

0102f34f1e Optimize QTextLayout/QTextEngine usage outside of QTextDocument.
When QTextLayout is used in a QTextDocument, many code paths use
special caches and thus greatly outperform the raw QTextLayout version
that operates directly on a QString.

This patch brings some of these optimizations also to the raw version.
We now also use a QFormatCollection in such cases and enable the
functionality of QTextEngine::indexAdditionalFormats() and
QTextEngine::resolveAdditionalFormats(). Thanks to that, we can greatly
speed up QTextEngine::format(), which now uses an amort O(1) hash table
lookup instead of a O(N) linear search.

The added benchmark shows a gain in the order of one magnitude:

./tst_bench_QText formattedLayout:long-many

before applying the patch:
378.19 msecs per iteration (total: 37,820, iterations: 100)
after applying the patch:
25.80 msecs per iteration (total: 2,580, iterations: 100)

Note: This change is source-incompatible for applications using the private
QTextEngine API.

b9ef4a9c30 Speed up sorting of dir entries when sorted by date
QDateTime will attempt to convert unknown types of date to UTC time, which isn't
exactly a fast process. As we don't care about local timezones in the process of
sorting (as this is purely for ordering, not display to the end user), we can
force the dates to use UTC time, avoiding the unnecessary local timezone lookup.

This also adds a benchmark covering this case.

Benchmark results, Qt 5:
 - before: 11, 489ms
 - after: 273ms

Qt 4.8:
 - before: 20, 848ms
 - after: 278ms

79b742b7e0 QtNetwork: use nullary version of qRegisterMetaType<T>("T")
Using the nullary version has the advantage that multiple calls
during a program run are much more efficient, since an inlined
atomic is used to store the result. It also ensures that
Q_DECLARE_METATYPE(T) has been used, whereas qRegisterMetaType<T>("T")
will happily register anything. So I've added the macro where it
was missing, or moved it to a central place when it existed
hidden.

In tst_qnetworkreply, this became a bit tricky, because a private
header is conditionally included, so moved the Q_DECLARE_METATYPE()
into a conditional section, too.

d359b0af2b Call QObject::disconnectNotify() when receiver is destroyed
Store the signal index in QObjectPrivate::Connection, thereby making
it available in "implicit" disconnect contexts (i.e., receiver
deletion).

This change does not cause the size of QObjectPrivate::Connection
to grow (still 40 bytes on 32-bit Linux, 72 bytes on 64-bit Mac).

Valgrinding the new benchmark indicates that the percentage of the
time spent in the QObject destructor increased from 7.8% to 8.4%
on ia32, for that particular stress test; the increase is the
combined cost of calling metaObject(), QMetaObjectPrivate::signal(),
and disconnectNotify() for one connection. In practice, the measured
wallclock time increased by about 3ms for a 500ms run (which
repeatedly constructs, connects, and destroys an object).

5230d62feb Partial fix for WebKit compilation on Windows
qdatetime.h uses std::min/max and on Windows windows.h (or some subsequent
header file) may under certain circumstances define min/max as macros.

The easiest way to prevent the windows header files from doing that is to
define NOMINMAX in the place right before windows.h is included. The other
way is to define min and max to min/max themselves to prevent windows.h
from doing its evil thing.

If a user of Qt (WebKit in this case) chooses the approach of defining
min/max to themselves and then includes qdatetime.h, then a subsequent
inclusion of windows.h doesn't work because qdatetime.h undefines min/max.

We should not enforce the type of workaround needed, therefore this patch
removes the workaround from qdatetime.h and requires user code that
happens to include windows header files before qdatetime.h (seldom case)
to choose either workaround.

7be255156f Deprecate qMemCopy/qMemSet in favour of their stdlib equivilents.
Just like qMalloc/qRealloc/qFree, there is absolutely no reason to wrap these
functions just to avoid an include, except to pay for it with worse runtime
performance.

On OS X, on byte sizes from 50 up to 1000, calling memset directly is 28-15%
faster(!) than adding an additional call to qMemSet. The advantage on sizes
above that is unmeasurable.

For qMemCopy, the benefits are a little more modest: 16-7%.

5cb0368516 Rewrite QMap to use a RB tree
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.

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().

The new layout matches that of QByteArrayData and QStringData, except
for offset which is measured from the beginning of QVectorData, whereas
in those classes it (still?) references the end of the header data.

The new layout uses an extra member for storing an offset into the data,
which will allow introducing QVector::fromRawData, similar to the same
functionality already existing in QString and QByteArray.

By not using an actual array to index array members, we also steer clear

7bbe79fe5f Drop file-engine abstraction from public API
This abstraction imposed serious performance penalties and is being
dropped from the public API.

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.

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.

5635823e17 Remove "All rights reserved" line from license headers.
As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

aee1f6cc41 Cleanup mess in public type ids.
There is no reason to keep two separated core types sets. It
couldn't be fixed before Qt5 because of binary compatibility promise.

This patch merges QMetaType core types with ext core types.

This "simple" operation consists of:
- QDataStream version was incremented, because type ids are
saved in QVariant's data stream.
- QMetaType LastExtCoreType and FirstExtCoreType were replaced by
LastCoreType, FirstCoreType and new QMetaType::HighestInternalId.
- New tests checking QVariant data stream for Qt4 and for Qt5 versions
were added.

Keep a QT_MODULE(x) define so other modules continue compiling.

This imports the JSON support for Qt 5 from
playground/qtbinaryjson.

It adds a fast, fully compliant json parser, a
convenient C++ API, conversion to and from
QVariants and a binary format for JSON that is
extremely fast to use together with the C++ API.
