I rewrote my PR 13515: * threading.excepthook() now gets a single argument which has multiple attributes: (exc_type, exc_value, exc_traceback, thread) * The default threading.excepthook() implementation in written in C which reduces the risk of missing symbol during Python shutdown. There is also a simple implementation in Python, for other Python implementations which don't want to implement _thread._excepthook() in C. * New _make_invoke_excepthook() function which handles the gory details for daemon threads. It creates a "local namespace" with references to all required functons and creates a _invoke_excepthook() function. * _invoke_excepthook() packs arguments as a C structseq / Python namedtuple (depending on the implementation), calls threading.excepthook(). If threading.excepthook() raises an exception, sys.excepthook() is called to handle it. -- First I also added a "stderr" argument to the arguments passed to threading.excepthook(): sys.stderr, or an old copy of sys.stderr if sys.stderr no longer exists or is set to None. But I decided to keep this as an implementation detail instead. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue1230540> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
