| * Change almost all other uses of qrand() to QRandomGeneratorThiago Macieira2017-11-082-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vast majority is actually switched to QRandomGenerator::bounded(), which gives a mostly uniform distribution over the [0, bound) range. There are very few floating point cases left, as many of those that did use floating point did not need to, after all. (I did leave some that were too ugly for me to understand) This commit also found a couple of calls to rand() instead of qrand().

| * 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.

Really, there isn't too much specific to benchmark here, but we're interested in one specific case: that of pushing and popping a single item repeatedly. With the current QVector behavior, this causes constant deallocation, which makes it morbidly slow. This behavior will be reviewed in a subsequent commit. Results (not that anyone really cares) for me: PASS : tst_QStack::qstack_push() RESULT : tst_QStack::qstack_push(): 1.9 msecs per iteration (total: 61, iterations: 32) PASS : tst_QStack::qstack_pop() RESULT : tst_QStack::qstack_pop(): 8.2 msecs per iteration (total: 66, iterations: 8) PASS : tst_QStack::qstack_pushpopone() RESULT : tst_QStack::qstack_pushpopone(): 80 msecs per iteration (total: 80, iterations: 1) Change-Id: I3530888abbfcfcef39318d6be6d5b07306a4704e Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Add QMetaType::type(QByteArray) functionKent Hansen2014-10-311-0/+18
| | | | | | | | | | | | | | | | | | | QMetaType::type(const char *) requires that the string argument is 0-terminated. This new overload makes it possible to query the type of a string with an explicit length. In particular, QByteArrays constructed by QByteArray::fromRawData(), for example from a substring of a normalized method signature (the "int" part of "mySlot(int"), can now be queried without making a copy of the string. Also, Qt5 meta-objects represent type names as QByteArray literals, which can be fed directly to this new QMetaType::type() overload (no need to call strlen).

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
