Subject: Fixes Issue #15507: test_subprocess's test_send_signal could fail if the test
X-Git-Tag: v3.4.0a2~77
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6cc50391a600b010d3cdc944d5355c93654da43f;p=python

Fixes Issue #15507: test_subprocess's test_send_signal could fail if the test
runner were run in an environment where the process inherited an ignore
setting for SIGINT.  Restore the SIGINT handler to the desired
KeyboardInterrupt raising one during that test.
