Description of problem: Python 3.10 and python-qt5-5.15.0-13 fail when doing this: >>> from PyQt5.QtCore import QByteArray >>> import pickle >>> pickle.dumps(QByteArray(b"test")) Traceback (most recent call last): File "<stdin>", line 1, in <module> SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats The bug has been fixed upstream and will be released in the next "snapshot", without having yet been formally released by the PyQt5 developer. The developer says the fix affects both PyQt5 and Pyqt5-sip. See for details https://www.riverbankcomputing.com/pipermail/pyqt/2021-October/044317.html This affects all PyQt5 programs in the Fedora archive that attempt to pickle QByteArray, such as Rapid Photo Downloader. Version-Release number of selected components: python-qt5-5.15.0-13.fc35 python3.10-3.10.0-1.fc35
The PyQt5 developer has released PyQt 5.15.6, which I can confirm has fixed the bug.
I'll look into updating the stack for f35 thanks.
