os-brick fail to get password from config file

[hamza]

for the change https://wiki.openstack.org/wiki/OSSN/OSSN-0086
in os-brick this line
https://github.com/openstack/os-brick/blob/b5891702cc24b0c9cedf6961d3223a37830341b9/os_brick/privileged/scaleio.py#L99
gives an error
Error getting ScaleIO connector password from configuration file: ConfigParser instance has no attribute '__getitem__'

i think it should be config.get(config_option, 'san_password')

steps to reproduce
openstack server add volume <server-id> <volume-id>

[hamza (alqtaishat)]

this fails on os-brick 2.8.5 using nova rocky

[Sean McGinnis (sean-mcginnis)]

These changes to os-brick have not been included in a stable release yet. Need to make sure nova, cinder, and os-brick all get updated with the credential handling change.

[hamza (alqtaishat)]

i already created the configuration file with the password and got all the changes needed
and changed the code to config.get(config_option, 'san_password') and it worked

[Brian Rosmaita (brian-rosmaita)]

I think the problem is that the parser['group']['key'] syntax was introduced in Python 3, so when you run under python 2.7 (which is still supported in Rocky), you get the "ConfigParser instance has no attribute '__getitem__'" error.

See https://docs.python.org/3/whatsnew/3.2.html#configparser

    Fix "Remove VxFlex OS credentials" regression

    Change Ia1d2b2151e5676037d40bfaf388b54023fc37093 uses a ConfigParser
    instance in a way that is incompatible with python 2.7, resulting in
    a "ConfigParser instance has no attribute '__getitem__'" error. This
    patch accesses the ConfigParser using the "old" API that works in both
    Python 2.7 and Python 3 and adds some tests.
