* QMacStyle: workaround NSSliderCell's cached/stale geometryTimur Pocheptsov2019-07-251-0/+35
| | | | | | | | | | | | It's a bit cheesy solution, but works as I've noticed first on QSlider's with a ticks direction 'both'. Works because we were already using numberOfTickMarks property to trigger a special behavior for HIG non-compliant widgets. Works for our case too - we trigger a geometry update.

* Implement 'preconnect-https' and 'preconnect-http' for H2Timur Pocheptsov2019-07-243-18/+52
| | | | | | | | | | | | | | | | | | | | | | | | QNetworkAccessManager::connectToHostEncrypted()/connectToHost() creates 'fake' requests with pseudo-schemes 'preconnect-https'/ 'preconnect-http'. QHttp2ProtocolHandler should handle this requests in a special way - reporting them immediately as finished (so that QNAM emits finished as it does in case of HTTP/1.1) and not trying to send anything. We also have to properly cache the connection - 'https' or 'http' scheme is too generic - it allows (unfortunately) mixing H2/HTTP/1.1 in a single connection in case an attribute was missing on a request, which is wrong. h2c is more complicated, since it needs a real request to negotiate the protocol switch to H2, with the current QNetworkHttpConnection(Channel)'s design it's not possible without large changes (aka regressions and new bugs introduced). Auto-test extended. Fixes: QTBUG-77082 Change-Id: I03467673a620c89784c2d36521020dc9d08aced7 Reviewed-by: Edward Welbourne <> Reviewed-by: Mårten Nordheim <>

* Optimize and fix handling of QtMessageHandlersMarc Mutz2019-07-111-15/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A function may almost always have static storage duration, but that does not necessarily mean that we can store and load pointers to them without memory ordering. Play it safe and use store-release and load-acquire for them (which combines to ordered for the fetchAndSet call in qInstall*Handler(), as we don't know what the caller will do with the returned function pointer). Also change the initial value of the atomic pointer to nullptr. Nullptr already signified the default handler in qInstall*Handler(), so the API doesn't change. But by using nullptr to mean default, we place these variables in the BSS segment instead of TEXT, save dynamic init, or at least a relocation, and we dodge the smelly comparison of function pointers, using comparison against nullptr instead. Also, as a drive-by, put the call to ungrabMessageHandler() in a scope-guard. Both the message handler, as well as the Qt code calling it (toLocal8Bit()!), may throw, and that would stop all further logging. In Qt 5.9, we can't use qScopeGuard(), yet, so use a local struct calling ungrabMessageHandler() in its dtor. The code still has one problem: When a logging action is underway, and another thread exchanges the message handler, we might still execute code in the old handler. This is probably not a problem in practice, since no-one will use a dynamically-compiled function for logging (right? :), but should probably be documented or fixed. This patch does not address this issue, though.

But on APFS, the filesystem is normalization- insensitive but preserves it, so our transformation caused valid files to be rejected. This commit also optimizes the solution for all systems too. Instead of converting from 8-bit to UTF-16 then back to 8-bit (allocating memory in both steps), we only convert to UTF-16. And if we detect the locale is UTF-8, then we use the further optimized QUtf8::isValidUtf8 function that doesn't allocate any memory at all (ditto for US-ASCII, the case of someone running with LANG=C).

| | | | | | | | | | | | | | | | | | | | | | In auto-test-enabled builds, QHostInfoCache can be enabled and disabled using qt_qhostinfo_enable_cache() at any time.

Under the assumption, then, that QHostInfoCache::enabled can be set by any thread at any time, and is read by any thread using QHostInfo::lookupHost(), we're presented with a data race, thus UB. Fix by making the accesses to QHostInfoCache::enabed atomic. Relaxed operations are suffcient, as the bool is the only data of interest in these situations. In particular, access to the cache itself is protected by the cache's mutex. We use std::atomic<bool> because QAtomicInteger<bool> doesn't exist on all implementations, but std::atomic<bool> must.

* Don't set the mouse cursor for items that are disabledVolker Hilsheimer2019-07-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | As with widgets, items that are disabled should not receive any input events. Similar to QGraphicsScene, which ignores disabled items when handling mouse presses, the view should also ignore them when handling mouse moves to update the cursor. Since QGraphicsView only adjusts the cursors on mouse moves, reenabling an item that is currently under the mouse will not change the cursor. This is consistent with other changes of item attributes that would position the item under the mouse (such as moving it). The overhead of hit-testing items for every such attribute change would be too large, and applications can generate a mouse move event if they really need to adjust the cursor in all situations.

| | | | | | | | | | | | | | | | | | | | | | | The plain bool variable wasDeleted is set to true in the QHostLookupManager dtor before the call to clear(), which calls waitForDone() on the thread pool performing the lookups.

But the check was outside the mutex-protected area, so as a non-atomic load, without a happens-before relation to the write, this is a Data Race, thus UB. Fix by moving the check past the mutex locking into the critical section. This way, tasks that were waiting for the mutex after seeing no wasDeleted before get the message reliably. This does not introduce a dead-lock, since the call to waitForDone() is outside any mutex protection leaving a window for the tasks to obtain the mutex and react on wasDeleted.

| | | | | | | | | | | | | A previous change to QLineEdit::sizeHint() has caused the QSpinBox arrows to break the widget frame on a high-DPI display with some particular scale values like 150 or 175%. This change updates QLineEdit::sizeHint() so that it has a minimum height, using the same values used in 5.11.

* Support pen color with color fontsEskil Abrahamsen Blomfeldt2019-07-0512-34/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Color fonts may also contain regular alphabet characters that should be rendered with the current pen. In Qt, however, these characters were drawn into the cache with a default pen color of black. Since all characters in a font is currently backed by the same cache, and it would require a lot of plumbing to get around this, a step in the right direction is to include the current pen color in the cache as long as it is an RGB cache. This means that drawing text with the color font with different pen colors will create different caches. There is no API to select font color on Freetype currently, but this problem has also not been observed there, as the fonts in question, with both regular and color glyphs, are not being detected as color fonts (so the text color will be correct). So Freetype will be left out for now. [ChangeLog][QtGui][Text] Fixed bug where regular text rendered with a color font would always display in black.

* Windows QPA: Fix blinking dot on Windows 7/8/8.1Andre de la Rocha2019-07-041-1/+8
| | | | | | | | | | | | | | | | A blinking white dot could appear on dark backgrounds on Windows 7/8/8.1. It was caused by a workaround added to trigger the on-screen keyboard on the Microsoft Surface. This change effectively restricts that workaround to Windows 10, where the blinking dot was not an issue. And anyway, impact over the Surface functionality should be minimal, as all models produced since 2015 only support Windows 10 (and it's unknown if the workaround was ever necessary for early models running Windows 8.1).

* Mark QObject::deleteLater() as \threadsafeMarc Mutz2019-07-031-0/+2
| | | | | | | | | | | | | | | | | | | | | Because it is. It's just QCoreApplication::postEvent(), which is thread-safe. It also _has_ to be, because we recommend to use deleteLater() to delete QObjects that live in another thread: Quoting the ~QObject() docs: > Warning: Deleting a QObject while pending events are waiting to be delivered > can cause a crash. You must not delete the QObject directly if it exists in > a different thread than the one currently executing. Use deleteLater() > instead, which will cause the event loop to delete the object after all > pending events have been delivered to it. If deleteLater() is not thread-safe, it cannot be used for one of its intended purposes. Change-Id: I333d506b42bdfcdff00fe6cefa234c21865625a6 Reviewed-by: Mårten Nordheim <>
