* Doc: Change instances of '(Mac) OS X' to 'macOS'Topi Reinio2016-08-1289-304/+304
| | | | | | | | | | | | | | | As of version 10.12 (Sierra), the name of Apple's desktop operating system will be macOS. Change the occurrences where the Mac platform is discussed to use a macro \macos, which expands to 'macOS'. This helps with adapting to future renaming. Update the instructions on mac-specific Q_OS_* macro usage. Add a \target for the old 'Qt for OS X' topic to keep links working for other documentation modules that try to link with the old name.

* QStringListModel: fix dataChanged's roles parameterMarc Mutz2016-08-121-1/+7
| | | | | | | | | | | | | In QStringListModel, the display and the edit roles are synonyms, so when one is changed, the other changes with it. However, in setData() we only emitted a vector with just the role that was passed in by the user. Fix by always passing both roles, regardless of which one was used to set the data.

* QTabBar: Cache title text sizesGabriel de Dietrich2016-08-102-32/+58
| | | | | | | | | | | | | | | | | | | The first part adds QTabBarPrivate::initBasicStyleOption() which is basically QTabBar::initStyleOption() but without the expensive QFontMetrics::elidedText() call. That is because QTabBar::tabSizeHint() would call initStyleOption() and then immediately discard the result of that computation. Then, QTabBar::tabSizeHint() is modified to cache the calls to QFontMetrics::size(), which is also expensive. The cache is invalidated when the style or the font changes, or when the elide mode is set.

| | | | | | | | | | | | | | | | | | | | | | 8a33077 made QUrl::resolved() follow its documentation ("If relative is not a relative URL, this function will return relative directly.", where relative means scheme is empty). However there is much code out there (e.g. qtdeclarative) which relies on QUrl::fromLocalFile("fileName.txt") to be treated as relative, so for now, we still allow this (in Qt 5.6.x). For Qt 5.8, this commit will be reverted. [ChangeLog][QtCore][QUrl] [EDITORIAL: replaces 8a33077] QUrl::resolved() no longer treats a URL with a scheme as a relative URL if it matches this URL's scheme. For now it still treats "file:name.txt" as relative for compatibility, but be warned that in Qt 5.8 it will no longer consider those to be relative. Both isRelative() and RFC 3986 say that such URLs are not relative, so starting from Qt 5.8, resolved() will return them as is.

| | | | | | | | | | | | | | | | | | | | | | | | | | | We can't forward a VerticalSortHint or HorizontalSortHint hint, because we might be filtering extra items. The documentation of QAbstractItemModel::LayoutChangeHint states: Note that VerticalSortHint and HorizontalSortHint carry the meaning that items are being moved within the same parent, not moved to a different parent in the model, and not filtered out or in. And some of the views rely on this assumption (QQmlDelegateModel for example) What happens in the test is the following: - 'model' emit the dataChanged signal when its data is changed. - 'proxi1' QSortFilterProxyModelPrivate::_q_sourceDataChanged does not forward the dataChanged signal imediatly, it will instead first re-sort the model and call layoutAboutToBeChanged / layouChanged with the VerticalSortHint - 'proxy2' would forward the layoutAboutToBeChanged with the hint, but in QSortFilterProxyModelPrivate::_q_sourceLayoutChanged, it will redo the mapping which will cause the changed data to be filtered. So proxy2 can't forward the VerticalSortHint as it removed rows in the process.

This would in turn invalidate the cache for every empty glyph, causing all glyphs to be rerendered for every isolated word. This change adds back a cut off. This is only needed in the lockedAlphaMapForGlyph() function, since the superclass implementation of the other alpha map functions already contains a cut off for width/height == 0.

* QColor: Fix UB (left shift of negative number)Marc Mutz2016-07-311-14/+20
| | | | | | | | | | | | | | | | | | | | | | If hex2int(const char*) is called with invalid input, it is expected to return a negative value. However, it didn't check the return value of h2i() before attempting a left-shift on it, leading to UB when the first digit was already invalid. UBSan agrees: qcolor_p.cpp:55:23: runtime error: left shift of negative value -1 This is particularly worrisome as the function can be called with unsanitized input. Fix by checking each value for non-negativity, returning -1 early when errors are detected. Also port to QtMiscUtils::fromHex() and add some docs.

| | | | | | | | | | | | | | | | | | | | Left-shifts of negative values are undefined in C++. In particular, they don't behave arithmetically. Reported by UBSan: qrasterizer.cpp:609:48: runtime error: left shift of negative value -640/-2240 qrasterizer.cpp:982:38: runtime error: left shift of negative value -2 Fix by using ordinary multiplication instead, because negative left-hand-side values don't look like they are an error. No errors were actually reported for a.y << 10, but I changed it nonetheless, since all a missing error means is that the test data didn't excercise this code path with negative Y values.

| | | | | | | | | | | | | | They look relative because the path doesn't start with a '/' but they have a scheme so they shouldn't be combined as if it was one absolute and one relative URL. [ChangeLog][QtCore][QUrl] QUrl::resolved() no longer treats a URL with a scheme as a relative URL if it matches this URL's scheme. This special casing was incompatible with RFC 3986 and broke resolving data: URLs, for instance.

* Fix for race condition in signal activationDenis Kormalev2016-07-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a race condition between QObject::disconnect() and QMetaObject::activate() which can occur if there are multiple BlockingQueued connections to one signal from different threads and they connect/disconnect their connections often. What can happen in this case is: T1 is in activate() method and T2 is in disconnect() method T1 T2 locks sender mutex selects next connection unlocks sender mutex locks sender mutex sets isSlotObject to false creates QMetaCallEvent derefs connection posts event Two things can happen here: 1. Connection can still be valid, but it will have isSlotObject==false and callFunction will be used instead of slotObj 2. Connection can already be invalid To fix it mutex unlock should be moved after QMetaCallEvent creation. Also there is another case, when we don't disconnect but delete the receiver object. In this case it can already be invalid during postEvent, so we need to move mutex unlock after postEvent.
