[3.9] bpo-42296: On Windows, fix CTRL+C regression (GH-23257)#23259
Merged
Conversation
On Windows, fix a regression in signal handling which prevented to interrupt a program using CTRL+C. The signal handler can be run in a thread different than the Python thread, in which case the test deciding if the thread can handle signals is wrong. On Windows, _PyEval_SignalReceived() now always sets eval_breaker to 1 since it cannot test _Py_ThreadCanHandleSignals(), and eval_frame_handle_pending() always calls _Py_ThreadCanHandleSignals() to recompute eval_breaker.
