* QDateTime - Add QTimeZone supportJohn Layt2013-09-231-1/+90

* Iterate over the smaller set in QSet::intersect().Mitch Curtis2013-06-052-0/+145
| | | | | | | | | | | | | | | | | | | | | | | | When calling intersect() on a large (1000000 items) QSet, with a small (1000 items) QSet as the argument, the function takes signifcantly longer than when the operand and the argument are reversed. This is because the operand set is always iterated over in its entirety. This patch changes intersect() to iterate over the smaller set. This reduces the large operand scenario's benchmark to ~0.000063 milliseconds, compared to the current ~134 milliseconds: 1000000.intersect(1000) = empty: 0.000063 (was 134) 1000.intersect(1000000) = empty: 0.000039 (was 0.000036) 1000000.intersect(1000) = 500: 0.10 vs (was 130) 1000.intersect(1000000) = 500: 0.023 vs (was 0.093) 1000000.intersect(1000) = 1000: 0.20 vs (was 139) 1000.intersect(1000000) = 1000: 0.017 vs (was 0.016) Task-number: QTBUG-22026 Change-Id: I54b25c49c78c458fef355e9c6222da8a64c7681f Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@digia.com> Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Remove QLocalePrivate::m_localeIDhjk2013-04-233-0/+89
| | | | | | | | | | | | | | It was only used for toUpper/toLower but always computed in the constructor, including QString::toLatin1 conversion and allocations. This needlessly slows down all other uses, including supposedly "cheap" operations QString::toDouble, or accesses inside QResourceFileEngine. The benchmarks indicates that doing it always when needed is bearable. There's still a lot of improvement potential on these code paths.

| | | | | | | | | | | | | | | | | | | | | 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().

* | 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.

| * tests: do not run benchmarks by default in 'make check'Sergio Ahumada2012-02-021-1/+0
| | | | | | | | | | | | | | | | | | `make check' is intended primarily for running functional tests. For the most part, it does not make sense to run benchmarks in the same test environment as the functional tests.

| * Allow function types to be registered without workaroundsJoão Abecasis2012-01-311-15/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 4b8ceb41aed352f10d36db5284453f425dbc5f3f added the requirement that pointed-to types need to be registered when registering pointer types. Unfortunately, the implementation also affects function pointer types. This change whitelists 0, 1, 2 and 3 argument functions as not deriving from QObject, forgoing the need to workaround details of the type registration implementation when registering those function pointer types.
