os.write exception errno 22

[Paul Hampson]

Hi,

I am trying to use the winpexpect library as a compatible drop in for pexpect for some test scripts we have.

You can see the relevant code here - https://github.com/xcore/sc_multi_uart/tree/automated_testing/test/serial_test/src in telnet_test.py

When the script is run I get the following exception:

Traceback (most recent call last):

  File "s2e_test.py", line 260, in <module>

    main()

  File "s2e_test.py", line 252, in main

    handle_telnet_tests(args, seed)

  File "s2e_test.py", line 162, in handle_telnet_tests

    test_pass += telnet_test.app_start_up_check_using_telnet()

  File "C:\Documents and Settings\User1\sandbox\sc_multi_uart\test\serial_test\s

    telnet_session = self.telnet_s2e_connect()

  File "C:\Documents and Settings\User1\sandbox\sc_multi_uart\test\serial_test\s

    telnet_session.sendline("")

  File "c:\Python27\lib\site-packages\winpexpect-1.5-py2.7.egg\pexpect.py", line

    n = n + self.send (os.linesep)

  File "c:\Python27\lib\site-packages\winpexpect-1.5-py2.7.egg\pexpect.py", line

 953, in send

    c = os.write(self.child_fd, s.encode('ascii'))

OSError: [Errno 22] Invalid argument

(This is reported as a bug here  - https://bitbucket.org/geertj/winpexpect/issue/7/oserror-errno-32-broken-pipe)

I am running this on windows XP with python2.7

Is there any progress on this issue/work around?

Thanks,

Paul
