* Add template text to \fn commands in qmap.cppMartin Smith2017-11-191-134/+146
| | | | | | | | | The \fn commands were not recognized by clang-qdoc because the template stuff was missing from the \fn commands. This update adds the correct template text and parameters. Change-Id: I7def18f35745b984cc1e2da7c351403d98d8668c Reviewed-by: Topi Reiniö <topi.reinio@qt.io>
* doc: Fix some "Cannot tie this..." errorsMartin Smith2017-11-173-5/+4
| | | | | | | | | | | | | These are errors where clangqdoc finds a qdoc comment, but it can't find anything in the API to associate it with. There are different causes. In many cases, soneone has documented a function that isn't in the public API so it should not be documented in the first place. In other cases, a function is platform-specific and we need to add || defined(Q_CLANG_QDOC) somewhere to make it visible.

* Avoid duplicate rules in QWinTimeZonePrivate::init()Edward Welbourne2017-11-151-2/+22
| | | | | | | | | | | | It was iterating the full range of years, adding a rule for each year. The rules have a startYear member and are used for later years until the next rule's startYear, so we don't need to duplicate them; and the system APIs we get them from do support recurrent rules (with wYear set to 0), that apply to ranges of years. So propagate that recurrence and reuse rules where we can. Change-Id: Ifdd292d3f3d3e07969d7a02bb01f2a0110d32950 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Restructure Dynamic TZ query to same form as Registry variantEdward Welbourne2017-11-151-17/+39
| | | | | | | | | | | | Break out the reading of an individual rule to a function and add a fall-back that tries to get a non-dynamic rule when there's no dynamic data for the zone. At the same time, change the first rule, in all cases to apply for all time (i.e. set its .startYear to MIN_YEAR, instead of 1970 or the advertised start range): we'll use it when extrapolating backwards into the past.

* Replace ruleForYear() method with a local index-based functionEdward Welbourne2017-11-152-16/+35
| | | | | | | | | | | Removed private method of QWinTimeZonePrivate in favor of a local static that returns a rule index rather than a rule; this prepares the way for smarter searching in transition-finding methods. In the process, re-work the function to use binary chop instead of a linear search through a potentially long sorted list.

* Add QFontMetrics(F)::horizontalAdvance() functionEskil Abrahamsen Blomfeldt2017-11-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | A source of constant confusion is the QFontMetrics::width() function, which does not return the bounding width of the text, but the advance width. We deprecate this and add horizontalAdvance() instead, to avoid the confusion in the future. Note that there was an internal width() overload which was only there for the purpose of supporting the Qt::TextBypassShaping flag. This flag has already been replaced by public API, so no such overload is added. Instead, we deprecate the TextBypassShaping flag as well, which makes sense, since a replacement has been made. Also note that there was a consistency problem with QFontMetrics and QFontMetricsF, which are supposed to be interchangeable. The QFontMetrics::width() functions for strings took an optional int length argument, while the floating point version did not. This error is corrected in the advance() functions. [ChangeLog][QtGui][Text] Added QFontMetrics::horizontalAdvance() and QFontMetricsF::horizontalAdvance() to replace the confusingly named width() function. The latter has now been deprecated.

* QDirIterator: Skip inconvertible file names on UnixAlexander Volkov2017-11-141-5/+12
| | | | | | | | | | | | | | | In the case when user's local encoding is UTF-8, QDirIterator may list entries which names can't be correctly converted from UTF-8 to UTF-16, e.g. for "\xC0\xB0" file name QDirIterator::fileName() returns "\uFFFD\uFFFD" (FFFD is a code of Replacement Character). The problem is that you can't do anything with such directory entries because there is no way to get the original entry names. List only those names that can be converted to QString and then back to the local encoding without corruption.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RENAME_NOREPLACE flag is supported for all Linux local filesystems, since that can be easily checked by the VFS layer (it knows which files exist and which ones don't). For non-local filesystems, the backend needs support and that might need server-side support too. So we may get EINVAL errors for those, in which case we fall back to link/unlink, which in turn can fall back to rename(). EINVAL can also happen if we attempt to make a directory a subdirectory of itself. In that case, we will attempt to link() it, which will result in EPERM as we can't hardlink directories. Then we try rename() again, which should result in the expected EINVAL.

Because the input was an unsigned 64-bit number, compilers needed to generate extra code to deal with HW instructions that only convert 64-bit signed input. And that was useless because a double uniformly distributed from 0 to 1 can only have 53 bits of randomness. The previous implementation did exactly what the Microsoft libstdc++ and libc++ implementations do. In my opinion, those implementations have an imperfect distribution, which is corrected in this commit. In those, all random input bigger than 0x20000000000000 has a different frequency compared to input below that mark. For example, both 0x20000000000000 and 0x20000000000001 produce the same result (4.8828125e-4). What's more, for the libc++ and MSVC implementations, input between 0xfffffffffffff001 and 0xffffffffffffffff results in 1.0 (probability 1 in 2⁵³), even though the Standard is very clear that the result should be strictly less than 1. GCC 7's libstdc++ doesn't have this issue, whereas the versions before would enter an infinite loop.

| | | * Improve performance in QThreadPoolSvenn-Arne Dragly2017-10-042-31/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When many runnables are executed, this improves the performance by not resizing the queue for each runnable, which was the case in the previous version, because of many calls to QVector::takeFirst(). Also add a test that makes sure tryTake() is safe to call and does not leave the queue in a bad state that tries to use nullptr entries.

* | | | QSemaphore: Improve waking up on 64-bit LinuxThiago Macieira2017-10-232-27/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By judiciously positioning of the bits, we can optimize for the case of threads trying to acquire a single token, which is what QSemaphore should be mostly used for, as it matches the POSIX Semaphore API (sem_wait, sem_timedwait and sem_trywait). If there are only waiters waiting for a single token, we know that adding n tokens means n threads can wake up. This optimizes for multi-token waiters too. For example, if we have 50 single-token waiters and 50 multi-token waiters, a sem.release(5) will wake up 55 threads instead of 100.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NSTimeInterval is a typedef for double, but the code stored its value in an int, and only then multiplied by 1000. Fix by only truncating NSTimeIntervals to int(64_t) *after* the multiplication by 1e3 to get milliseconds. While it's highly unlikely that a transition will have fractional seconds length, don't assume if you can just calculate the more exact result.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Auto-reset events are automatically reset to non-signaled when we get notified about the signaled state. This implies that we cannot check the event state again in activateEventNotifiers. Instead, store the signaled state in a QAtomicInt and test and decrement that. This amends commit 85403d0a.
