* Flickable: handle child mouse ungrab when hidden or disabledJ-P Nurmi2017-02-081-1/+4
| | | | | | | | | | | | If Flickable got hidden while a child had mouse grab, it ignored the mouse ungrab event of the child mouse grabber, and got therefore stuck in pressed state. Consequently, item view transitions were not executed since the item view though it was being pressed.

* QQuickMouseArea: only start pressAndHoldTimer for accepted eventsRichard Moe Gustavsen2017-02-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | Most likely because of changes done to mouse event handling in 5.8, a QQuickMouseArea can now get a mousePressEvent call without a subsequent mouseReleaseEvent call if the press event was rejected. A regression seen from this is that QQuickMouseArea starts a pressAndHold timer upon receiving mouse press, which will never be 'cancelled' since the following mouse release is sent elsewhere. As a result, TextArea in QtQuickControls will e.g receive a pressAndHold signal each time the user touches the control, which again will cause weird behavior like selecting words and messing with focus on iOS. This patch will instead change this so that we only start the pressAndHold timer if QQuickMouseArea accepts the mouse press event.

* Fix move ordering while resolving edges in register allocationErik Verbruggen2017-02-044-67/+104
| | | | | | | | | | | | | | | | | | When register allocation on an IR in SSA form is done, the last step is to turn the Phi nodes into moves and swaps and put those instructions in the predecessors. As the Phi nodes are conceptually "executed in parallel", this can result in cycles: r1 <- r0 r0 <- r1 These have to be turned into a swap instruction. Also, the moves have to be ordered in order to make sure that no values are overwritten: r1 <- r0 r2 <- r1 Here the two moves need to be switched. The comments in the code document the algorithm.

| | | | | | | | | | | | | | | | | | Transitions contain both an id and a set of flags, but the sorting failed to take the flags into account in the operator<. As a result we would some times end up with duplicate entries if the same id was added multiple times with different flags. If the same id was added again and again with varying flags, this could lead to an ever expanding list filled with duplicate entries. Fix this by also taking flags into account in operator< so that operator< and operator== are symetric and the list gets correctly sorted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a regression from commit 7e14b531b294650733a61a9365eb9ef74f8a7a90, that replaced a QHash<temp, liveInterval> with a vector of intervals. When an interval is split, it may happen that during one interval a temp is stored in a register and in the second interval it ends up in a different register or the stack. The _liveIntervals variable, formerly the _intervalForTemp hash, tracked the intervals per temp when going through the basic blocks and statements during the renumbering phase. Indexing uniquely by temp is important therefore for _liveIntervals and addNewIntervals violated that by replacing the QHash replacement _intervalForTemp[i->temp()] = i; with _liveIntervals.push_back(i); This is how we may end up with multiple intervals for the same temp (in different locations), and when doing the linear lookup we'd only find the first. Restoring the replacement behavior and thus ensuring uniqueness by temp fixes the miscompilations.

Therefore, deleting a top level layout might trigger item change listeners for *all* its descendants, not only its direct children. This behavior might even cause crashes: The visibility changes will then trigger an invalidation of the layout, which will propagate up the parent hierarchy, and potentially call invalidate() on a partially-destroyed layout, which then might crash.

* | Fix QML cache not being invalidated when source path changesSimon Hausmann2017-01-021-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | When somebody renames the directory name underneath a QML file and its cache file, then we need to re-generate the cache as it contains the fully path of the source path. That is sometimes used to resolve relative URLs (such as images) and therefore needs updating (by re-creating the cache).

* | QQuickWindow flushFrameSynchronousEvents: don't hover if nothing dirtyShawn Rutledge2016-12-281-2/+3

For example, any QtQuick-based Wayland compositor needs to notify its client windows when hover state changes, so calling this method too often would impose extra work to double-check whether it really changed or not.
