* bpo-1054041: Exit properly by a signal after a ^C. An uncaught KeyboardInterrupt exception means the user pressed ^C and our code did not handle it. Programs that install SIGINT handlers are supposed to reraise the SIGINT signal to the SIG_DFL handler in order to exit in a manner that their calling process can detect that they died due to a Ctrl-C. https://www.cons.org/cracauer/sigint.html After this change on POSIX systems while true; do python -c 'import time; time.sleep(23)'; done can be stopped via a simple Ctrl-C instead of the shell infinitely restarting a new python process. What to do on Windows, or if anything needs to be done there has not yet been determined. That belongs in its own PR. TODO(gpshead): A unittest for this behavior is still needed. * Do the unhandled ^C check after pymain_free. * Return STATUS_CONTROL_C_EXIT on Windows. * Fix ifdef around unistd.h include. * 📜🤖 Added by blurb_it. * Add STATUS_CTRL_C_EXIT to the os module on Windows * Add unittests. * Don't send CTRL_C_EVENT in the Windows test. It was causing CI systems to bail out of the entire test suite. See https://dev.azure.com/Python/cpython/_build/results?buildId=37980 for example. * Correct posix test (fail on macOS?) check. * STATUS_CONTROL_C_EXIT must be unsigned. * Improve the error message. * test typo :) * Skip if the bash version is too old. ...and rename the windows test to reflect what it does. * min bash version is 4.4, detect no bash. * restore a blank line i didn't mean to delete. * PyErr_Occurred() before the Py_DECREF(co); * Don't add os.STATUS_CONTROL_C_EXIT as a constant. * Update the Windows test comment. * Refactor common logic into a run_eval_code_obj fn.
