* Restore compatibility with pre-5.9 Keccak calculationThiago Macieira2017-09-211-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 12c5264d9add1826d543c36d893db77262195fc6 fixed the calculation of SHA-3 in QCryptographicHash: we were previously calculating Keccak. Unfortunately, turns out that replacing the algorithm wasn't the best idea: there are people who need to compare with the result obtained from a previous version of Qt and stored somewhere. This commit restores the enum values 7 through 10 to mean Keccak and moves SHA-3 to 12 through 15. The "Sha3_nnn" enums will switch between the two according to the QT_SHA3_KECCAK_COMPAT macro. [ChangeLog][Important Behavior Changes] This version of Qt restores compatibility with pre-5.9.0 calculation of QCryptographicHash algorithms that were labelled "Sha3_nnn": that is, applications compiled with old versions of Qt will continue using the Keccak algorithm. Applications recompiled with this version will use SHA-3, unless QT_SHA3_KECCAK_COMPAT is #define'd prior to #include <QCryptographicHash>. [ChangeLog][Binary Compatibility Note] This version of Qt changes the values assigned to enumerations QCryptographicHash::Sha3_nnn. Applications compiled with this version and using those enumerations will not work with Qt 5.9.0 and 5.9.1, unless QT_SHA3_KECCAK_COMPAT is defined.

* | Unify and optimize QByteArray::to{Upper,Lower}Thiago Macieira2014-08-192-1/+189
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do a check first if we need to transform before doing the transform. This means we won't detach when transforming data that is already correct. And instead of using QChar, use our own hand-rolled table. In a proper LTO build, the QChar calls would be resolved to a lookup of the Unicode data, but not many people do LTO builds, Therefore, this means a great speed-up is achieved by simply avoiding the function call. The extra gain in performance comes from the simpler translation table instead of the more complex full-Unicode data. Also as a consequence, this changes the handling of two characters in Latin 1: 'ß' should be uppercased to "SS" but we won't do it, and 'ÿ' can't be uppercased in Latin 1 ('Ÿ' is outside the range). Benchmarking is included. Comparing the Qt 5.4 algorithm to the new code is almost 20x faster. Other alternatives are included in the benchmark and are all faster than the current code, though slower than the new one. While all of them could compress the tables to be smaller or shared between uppercasing and lowercasing, they would also expand to more code (though probably less than the extra bytes required in the full translation table). In the trade-off, I decided to go with simplicity and most efficient code. Change-Id: I002d98318d236de0d27ffbea39d662cbed359985 Reviewed-by: Marc Mutz <marc.mutz@kdab.com>

* Update the qHash function for strings to use the CRC32 instructionThiago Macieira2014-01-233-14/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to my profiling of Qt Creator, qHash and the SHA-1 calculation are the hottest spots remaining in QtCore. The current qHash function is not really vectorizable. We could come up with a different algorithm that is more SIMD-friendly, but since we have the CRC32 instruction that can read 32- and 64-bit entities, we're set. This commit also updates the benchmark for QHash and benchmarks both the hashing function itself and the QHash class. The updated benchmarks for the CRC32 on my machine shows that the hashing function is *always* improved, but the hashing isn't always. In particular, the current algorithm is better for the "numbers" case, for which the data sample differs in very few bits. The new code is 33% slower for that particular case. On average, the improvement (including the "numbers" case) is: compared to qHash only QHash Qt 5.0 function 2.54x 1.06x Qt 4.x function 4.34x 1.34x Java function 2.71x 1.11x Test machine: Sandybridge Core i7-2620M @ 2.66 GHz with turbo disabled for the benchmarks Change-Id: Ia80b98c0e20d785816f7a7f6ddf40b4b302c7297 Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@digia.com> Reviewed-by: Lars Knoll <lars.knoll@digia.com> Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | Changed the processing of non-character code handling in the UTF8 codec. Non-character codes are now accepted in QStrings, QUrls and QJson strings. Unit tests were adapted accordingly. For more info about non-character codes, see: http://www.unicode.org/versions/corrigendum9.html [ChangeLog][QtCore][QUtf8] UTF-8 now accepts non-character unicode points; these are not replaced by the replacement character anymore [ChangeLog][QtCore][QUrl] QUrl now fully accepts non-character unicode points; they are encoded as percent characters; they can also be pretty decoded [ChangeLog][QtCore][QJson] The Writer and the Parser now fully accept non-character unicode points.

* 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.
