* QRegularExpression: refactor pattern optimizationGiuseppe D'Angelo2018-06-222-77/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the move to PCRE2, optimizing patterns has been a thorn in the side due to the fact that PCRE2's JIT compiler modifies the pattern object itself (instead of returning a new set of data, like PCRE1 did). To make this fit with the existing behavior, a read/write lock was introduced, with the read part locking when matching and the write when compiling (or JIT-compiling) the pattern. This locking strategy however introduced a performance issue, as we needed: * to acquire a write lock to compile/optimize the pattern (incl. the common case where the pattern was already compiled, so bailing out immediately); * to acquire a read lock during the actual match, to prevent some other thread from optimizing the pattern under our nose. This was due to the "lazy" optimization policy of QRegularExpression -- optimize a pattern after a certain number of usages. The excessive amount of locking effectively limited scalability. Simplify the code, and drop that policy altogether: since JIT compiling in PCRE2 is faster and pretty much "always recommended", just always do it for any pattern (unless it gets disabled via env variables) when compiling it. This allows to go back to a plain QMutex, and now the actual matching doesn't require acquiring any locks any longer. Of course, there is still a mutex acquired just before matching for checking whether the pattern needs recompiling in the first place; this can probably be further optimized via double-checked locking (using atomics), but not doing it right now. This shift makes a couple of pattern options controlling optimization useless, and allows to centralize the 3 QRegularExpression tests (which were actually the very same test, just setting slightly different optimizations strategies). While at it, install a stress-test for threading, with the idea of running it under TSAN or helgrind to catch bugs in QRegularExpression's locking. [ChangeLog][Important Behavior Changes][QRegularExpression] Regular expressions are now automatically optimized (including JIT compiling) on their first usage. The pattern options OptimizeOnFirstUsageOption and DontAutomaticallyOptimizeOption no longer have any effect, and will get removed in a future version of Qt. QRegularExpression::optimize() can be still used to compile and optimize the regular expression in advance (before any match), if needed.

* Add ObjectMode coordinate mode to QGradientEirik Aavitsland2018-06-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | The ObjectBoundingMode coordinate mode of QGradient allows specifying the gradient coordinates relative to the object being painted. But if the gradient brush also has a transformation, that transformation is applied in the logical, not object, coordinate space. That behavior is counterintuitive. However, changing it now would break existing code. Instead, we introduce a new coordinate mode enum with the expected behavior, and document the old one as deprecated. This prepares to fix the bugs below in qtsvg, by making it possible to specify the same behavior in Qt as SVG has.

* Make the stub implementation of QThread compile againUlf Hermann2018-06-223-10/+40
| | | | | | | | | | | | | | | | We cannot inline methods of QThreadPrivate because QThreadData has to be declared before. The global QThreadData needs to be accessible to QThreadData::clearCurrentThreadData(), and QAdoptedThread::run() has to be moved inside the #ifndef QT_NO_THREAD block as run() doesn't exist in the stub and Q_DECL_OVERRIDE would be wrong. We also fix the QThreadData::current() method to take and use the same parameters as in the non-stub case.

| * QLocale: only use LANGUAGE if it contradicts LC_ALL/LC_MESSAGES/LANGEdward Welbourne2018-05-231-3/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If LANGUAGE specified only the language, without any script or country, and matched the value we'd got from other environment variables, we were throwing away their knowledge of script and country, leading to falling back on the default script and country for that language, which might be at odds with what other environment variables had told us. Changed to only use LANGUAGE if it contradicts (or extends) what we would otherwise have used. Clarified some comments in the process. [ChangeLog][QLocale][Unix] When using LANGUAGE would lose information about script or country, without changing language, use the locale implied by LC_ALL, LC_MESSAGES or LANG.

| | | | | | | | | | | | | | | | | | Turns out that the non-AVX2 code was beating the performance of the AVX2 because the simdTestMask function did a little too much. So just use the same VPMOVMSKB technique for it. Change-Id: I0825ff5b5f6f4c85939ffffd152f3b636ab998db Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io>
