* Plumb public permission APIs to Android backendTor Arne Vestbø2022-11-092-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | The lock and unlock of the Android deadlock mutex is now part of the internal implementation instead of limited to the enum based permission API. It is unclear why 8bca441b6f65 added the guard only to this API and not to the string based API as well. The check for isBackgroundLocationApi29 has been removed, as the logic seemingly resulted in accepting every single permission type except location permissions if used via the enum-based API. Since Android's platform permission API doesn't have an Undetermined status, we keep a hash of the status for each permission type, and by default checkPermission() would return Undetermined, until a requestPermission() call is done which updates the internal hash, and after that checkPermission() would return properly Granted/Denied.

* Add permission API backend for macOS and iOSTimur Pocheptsov2022-11-032-0/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When submitting applications to the iOS and macOS AppStore the application goes through static analysis, which will trigger on uses of various privacy protected APIs, unless the application has a corresponding usage description for the permission in the Info.plist file. This applies even if the application never requests the given permission, but just links to a Qt library that has the offending symbols or library dependencies. To ensure that the application does not have to add usage descriptions to their Info.plist for permissions they never plan to use we split up the various permission implementations into small static libraries that register with the Qt plugin mechanism as permission backends. We can then inspect the application's Info.plist at configure time and only add the relevant static permission libraries. Furthermore, since some permissions can be checked without any usage description, we allow the implementation to be split up into two separate translation units. By putting the request in its own translation unit we can selectively include it during linking by telling the linker to look for a special symbol. This is useful for libraries such as Qt Multimedia who would like to check the current permission status, but without needing to request any permission of its own.

* Long live QPermissions!Tor Arne Vestbø2022-11-012-0/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many features of today's devices and operating systems can have significant privacy, security, and performance implications if misused. It's therefore increasingly common for platforms to require explicit consent from the user before accessing these features. The Qt permission APIs allow the application to check or request permission for such features in a cross platform manner. The check is always synchronous, and can be used in both library and application code, from any thread. The request is asynchronous, and should be initiated from application code on the main thread. The result of the request can be delivered to lambdas, standalone functions, or regular member functions such as slots, with an optional context parameter to manage the lifetime of the request. Individual permissions are distinct types, not enum values, and can be added and extended at a later point.

It is also common in such applications to offer a shortcut editor in the preferences or separately in a dialog.
