[Development] Feature freeze exception for QTBUG-95587
Hello, due to the magnitude of the above mentioned bug, I'm considerng to introduce a new feature in Qt 6.2.1. The new "@" operator in QML relieves you from typing "Qt.resolvedUrl" over and over. See https://codereview.qt-project.org/c/qt/qtdeclarative/+/369987 Now the question is whether we want to relax the feature freeze for this particular issue or not. Some background: In Qt5, the QML engine resolves a relative URL as soon as it is assigned to any property of type "url" or QUrl. This means that you cannot store relative URLs in such properties, and reading such a property back in QML gives you a different value than the one you have written. The base URL used for resolving is the URL of the QML document where the assignment happens. This is often not the place where the URL is meant to be resolved. There were a number of bug reports about these shortcomings in Qt5, especially when combined with URL interception and/or redirection. See for example QTBUG-81244 QTBUG-88965 QTBUG-66690 QTBUG-76879 In Qt6, URLs are simply not resolved anymore when assigning them to a property. This conveniently gets rid of all the cruft and inconsistency resulting from the Qt5 behavior. Instead the individual elements using URLs (Image, ShaderEffect, ...) are free to resolve them to their liking. There is suitable functionality exported from QtQml to do that. Now, there is one problem, QTBUG-95587: The original context where a URL was first assigned to a property is not easily available to the final consumer of the URL. At the same time, the element consuming the URL might be deeply nested in the implementation details of some module and might have a rather internal base URL. In this case, the URL as resolved by the consumer is not very useful. A user can fix this by explicitly calling Qt.resolvedUrl() in order to resolve the URL in a specific context and make it absolute. As we need URLs rather often in QML, we will see much more Qt.resolvedUrl() in Qt6 than we have seen in Qt5. As Qt.resolvedUrl() is quite a mouthful, there should be a shorthand for it: the '@' operator. So, is this bad enough for an exception, or should we rather live with Qt.resolvedUrl() in 6.2. I'm tentatively in favor of the exception because 6.2 is a rather important release and this is a rather ugly wart in the QML language. best regards, Ulf ___ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
