The
ResourceWarningfromtest_https_client_non_tls_response_ignored(the third case here) has a cause inhttp.client:HTTPConnection.connect()leavesself.sockopen whensetsockopt(TCP_NODELAY)fails, and on macOS that call raisesEINVALonce the peer has reset the connection, which is what that test's server does. Reported with details as gh-157174, fix in #157175. The twopreauthcases leak anSSLSocketand look like a different path.
