#918 Fix WantReadError in _bootstrap_ssl_from_server Pull request opened by jeevb Summary • Fix

WantReadError

/

WantWriteError

raised by pyOpenSSL's

do_handshake()

when

socket.create_connection()

leaves the fd in non-blocking mode (O_NONBLOCK set for any timeout > 0). Restore blocking mode with

sock.settimeout(None)

before the TLS handshake. • Improve resource cleanup: close the raw socket if

SSL.Connection()

fails before

conn

is assigned. • Add tests for empty cert chain, successful close, and socket cleanup on connection setup failure. • Assert that

settimeout(None)

is called on the socket, directly covering the core fix. Test plan •

pytest tests/flyte/remote/test_session.py::TestBootstrapSslFromServer

— all 5 tests pass • Manual verification against a Flyte cluster with

insecure_skip_verify=True
