* QTimeZone: don't use QSet, use sorted QListMarc Mutz2015-02-171-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | QSet, as a node-based container, requires one memory allocation per element inserted. QList, as a contiguous-memory container (at least in the case of a QByteArray payload), requires one memory allocation per container. The higher lookup speed might still speak for using QSet, but there are only two uses of the sets: 1. Checking for existence (or lack thereof) of timezone names. For this, first generating a container full of data just to check for existence of one item of data is extremely wasteful. The QTZPrivate API should be extended to allow said lookup to be performed on the native data store instead. That leaves 2. Returning a sorted(!) list(!) from the public QTimeZone API. There is no reason why, during the construction of those sorted lists, the data should be held in a set. Instead, the well-known technique of first cramming everything into a result container, which is subsequently sorted and has its duplicates removed, can be used here. Saves more than 8K of text size on AMD64 stripped release builds. Change-Id: I71c2298e94e02d55b0c9fb6f7ebeaed79a1fe2db Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

* QTzTimeZonePrivate: replace an inefficient QList with QVector (IV)Marc Mutz2015-02-121-17/+17
| | | | | | | | | | | | | | The QTimeZonePrivate::Data type is larger than void*, so holding them in QLists is horribly inefficient. In addition, this type is held elsewhere in QVector, so do that here, too. As well as being faster, also saves 1.3K of text size on optimized AMD64 builds.

* QTzTimeZonePrivate: replace an inefficient QList with QVector (III)Marc Mutz2015-02-121-15/+16
| | | | | | | | | | | | | | The implementation-private QTzType type is larger than void*, so holding them in QLists is horribly inefficient. Fix by holding it in QVector instead (it was already marked as a primitive type before). Text size grows by ca. 0.5K, but of course we got rid of all those pesky heap allocations.

* QTzTimeZonePrivate: replace an inefficient QList with QVector (II)Marc Mutz2015-02-121-13/+12
| | | | | | | | | | | | | | | | | | The implementation-private QTzTransition type is larger than void*, so holding them in QLists is horribly inefficient. Fix by declaring it as a primitive types (it just contains various integers) and holding it in QVector instead. Also optimize parseTzTransitions() by preallocating the expected number of transitions and streaming directly into the container, resizing to the number of successful read items on error. Saves roughly 0.5K in text size, too.

* Update copyright headersJani Heikkinen2015-02-111-6/+6
| | | | | | | | | | | | | | | | | | 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 <matti.paaso@theqtcompany.com>
* Don't use QStringLiteral in comparisonsMarc Mutz2014-10-091-2/+2
| | | | | | | | | | | | | | For QLatin1String, operator== is overloaded, so comparing to a latin-1 (C) string literal is efficient, since strlen() is comparatively fast. OTOH, QStringLiteral, when not using RVO, litters the code with QString dtor calls, which are not inline. Worse, absent lambdas, it even allocates memory. So, just compare using QLatin1String instead. Change-Id: I7af3bf3a67c55dae33ffaf9922d004fa168a3f9c Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
