| * wasm: add platform qsettingsLorn Potter2019-11-141-18/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the backend is async, the settings will not be ready to read/write instantly as on other platforms, but only be ready after the filesystem has been synced to the sandbox. This takes at least 250 to 500 ms. The QSettings status() or isWritable() can be used to discern when the settings are ready for use. This also fixes a crash in threaded wasm Task-number: QTBUG-70002 Fixes: QTBUG-63923 Fixes: QTBUG-79650 Change-Id: If24c6ada1b91b2a565ed6733da74972c3027f622 Reviewed-by: Edward Welbourne <edward.welbourne@qt.io> Reviewed-by: Morten Johan Sørvig <morten.sorvig@qt.io>
| * Make QObjectPrivate::threadData a proper atomicGiuseppe D'Angelo2019-11-131-56/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QObjectPrivate::threadData used to be a QThreadData *, and was read and written from multiple threads without proper synchronization. As an example, it was read from QCoreApplication::postEvent and written from QObject::moveToThread, therefore causing UB. Port threadData to a proper atomic, removing the races. Fix all usage points. In general, QObject is documented to be simply reentrant, not thread-safe, and certain bits (e.g. timers, moveToThread) are not even reentrant. The reasoning therefore is that a given QObject's threadData is not supposed to be touched by multiple threads without some synchronization happening elsewhere, and therefore relaxed loads should be sufficient. As drive-by change: refactor QCoreApplication::postEvent. It was particularly subtle, because it had a loop using a volatile to cope with the possibility of the receiver object switching thread while we tried to lock its thread's event queue. However, volatile does not achieve any synchronization, so drop it, and refactor the algorithm using better locking primitives. Put this algorithm in a common place, and also reuse it from removePostedEvents, which was lacking any synchronization.

| * Android: Fix loading of pluginsBogDan Vatra2019-09-221-10/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In 5bb178c479a247720fbc3fbb7f06a32b725193ac, the Android platform plugin was moved from platforms/android to platforms/. The unforeseen consequence of this was that the plugin loader for plugins/platforms would now find it, whereas before it would be ignored. It would therefore be detected as the appropriate plugin, but since it was intended to be loaded as a static plugin, loading it dynamically would fail. Instead of fixing the static plugin loading, we remove this hack.

This is easily fixed by splitting libraryPaths() into public libraryPaths() and private libraryPathsLocked(), the latter expecting to be called with the libraryPathMutex already held. And this is what this patch does. However, on second glance, the building of the initial app_libpaths calls a monstrous amount of code, incl. QLibraryInfo, and some of that code probably re-enters one of the library-path functions. So while this patch is a step towards making libraryPathMutex non-recursive, it's probably not the end.
