* Move QTriangulator and QTriangulatingStroker classes to paintingAndy Nichols2016-08-151-2377/+0
| | | | | | | | | | | | | | Previously the private APIs for QTriangulator and QTriangulatingStroker were located in src/gui/opengl because they were used by the OpenGL paint engine. These API's are not actually specific to OpenGL however, and were not being built when QT_NO_OPENGL was defined. It makes more sense for these classes to belong in the painting subgroup. Aside from the OpenGL paint engine, these private APIs are used by QtLocation to triangulate polylines to be rendered by QtQuick.

* Use C++ <cmath> instead of <math.h>Allan Sandfeld Jensen2015-02-161-5/+3
| | | | | | | | | | | | | | Including math.h can pollute the default namespace, and break some compilers if cmath versions of the method are declared as using. Switching to C++ math functions also greatly simplifies handling of float qreal as C++ automatically chooses the right method. [ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any sources depending on that indirect inclusion may fail to build.

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <[email protected]>
* QTriangulator: fix a potential out of bounds accessGiuseppe D'Angelo2014-10-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | primeForCount tries to calculate a rough base 2 logarithm of the argument, in order to access the array of deltas between primes. However, the usage of an arithmetic shift instead of a logical shift could cause "high" to stay at 32 -- if the argument is INT_MAX, for instance, the condition of the if clause in the loop is always true. The loop would go this way: * precond: low = 0 , high = 32 * i = 0 : mid = 16, if TRUE, low = 16, high = 32 * i = 1 : mid = 24, if TRUE, low = 24, high = 32 * i = 2 : mid = 28, if TRUE, low = 28, high = 32 * i = 3 : mid = 30, if TRUE, low = 30, high = 32 * i = 4 : mid = 31, if TRUE, low = 31, high = 32 and hence the subsequent access of the 33rd position of the array (by passing index 32) is out of bounds. Now the if at i = 4 is true because "1 << 31" is an arithmetic shift, not a logical one, and gives - (2^31) as result. Making it a logical shift fixes this (INT_MAX is 2^31-1, the shift gives 2^31, so the if is false). Spotted by Coverity.

* Remove custom sort implementation in QTriangulator in favour of std::sort.Robin Burchell2012-09-041-126/+3
| | | | | | | | | | | | | | qSort has terrible performance, especially on mostly-sorted input, which is presumably why a custom implementation was created. However, std::sort has much better performance than qSort in many cases. Benchmarking shows that std::sort beats out the custom sort by a very narrow margin (21-22ms for qSort, 14-15ms for sort, 14ms for std::sort) in a simple benchmark of sorting.
