I would prefer to keep the test but make sure that TIOCSWINSZ is positive.

I wrote a different fix: #119840

if not pty:
raise unittest.SkipTest('pty module required')
mfd, sfd = pty.openpty()
try:
if termios.TIOCSWINSZ < 0:
set_winsz_opcode_maybe_neg = termios.TIOCSWINSZ
set_winsz_opcode_pos = termios.TIOCSWINSZ & 0xffffffff
else:
set_winsz_opcode_pos = termios.TIOCSWINSZ
set_winsz_opcode_maybe_neg, = struct.unpack("i",
struct.pack("I", termios.TIOCSWINSZ))

our_winsz = struct.pack("HHHH",80,25,0,0)
# test both with a positive and potentially negative ioctl code
new_winsz = fcntl.ioctl(mfd, set_winsz_opcode_pos, our_winsz)
new_winsz = fcntl.ioctl(mfd, set_winsz_opcode_maybe_neg, our_winsz)
finally:
os.close(mfd)
os.close(sfd)
