Local Redfish does not correctly transition between bytes and string in Python 3

Hi,

I’m trying to use this library for monitoring the health of some servers I’m using. I began adapting the simple redfish-quickstart file that’s available under the examples directory. As per instructions, I also have hprest_chif.so available on my system. The relevant part of the script is below:

import redfish

# When running on the server locally use the following commented values
iLO_host = "blobstore://."
iLO_account = "None"
iLO_password = "None"


redfish_obj = redfish.redfish_client(base_url=iLO_host,
                                     username=iLO_host,
                                     password=iLO_password)

redfish_obj.login(auth="session")

When I try to run this with python3.6, I get the following errors:

Traceback (most recent call last): 
  File "/usr/lib/python3.6/site-packages/redfish/rest/v1.py", line 955, in __init__
    password=password) 
  File "/usr/lib/python3.6/site-packages/redfish/hpilo/risblobstore2.py", line 858, in initializecreds
    dll = BlobStore2.gethprestchifhandle()
  File "/usr/lib/python3.6/site-packages/redfish/hpilo/risblobstore2.py", line 837, in gethprestchifhandle
    raise ChifDllMissingError(excp)
redfish.hpilo.risblobstore2.ChifDllMissingError: '_Environ' object has no attribute 'has_key'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "check_memory_status.py", line 16, in <module>
    password=iLO_password)
  File "/usr/lib/python3.6/site-packages/redfish/rest/v1.py", line 1226, in get_client_instance
    is_redfish=is_redfish, cache=cache, proxy=proxy)
  File "/usr/lib/python3.6/site-packages/redfish/rest/v1.py", line 966, in __init__
    if excp.message == 'chif': 
AttributeError: 'ChifDllMissingError' object has no attribute 'message'

When I try running with python 2.7:

Traceback (most recent call last): 
  File "check_memory_status.py", line 16, in <module>
    password=iLO_password) 
  File "/usr/lib/python2.7/site-packages/redfish/rest/v1.py", line 1226, in get_client_instance

    dll = BlobStore2.gethprestchifhandle()
  File "/usr/lib/python2.7/site-packages/redfish/hpilo/risblobstore2.py", line 835, in gethprestchifhandle
    BlobStore2.setglobalhprestchifrandnumber(libhandle)
  File "/usr/lib/python2.7/site-packages/redfish/hpilo/risblobstore2.py", line 846, in setglobalhprestchifrandnumber
    libbhndl.updaterandval.argtypes = [c_ushort]
  File "/usr/lib64/python2.7/ctypes/__init__.py", line 373, in __getattr__
    func = self.__getitem__(name)
  File "/usr/lib64/python2.7/ctypes/__init__.py", line 378, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self)) 
AttributeError: /lib64/hprest_chif.so: undefined symbol: updaterandval

Remote connections (using an explicit IP address) to connect to the iLO works fine but I want to avoid using hardcoded IPs and account credentials in my script. Any help to fix these issues would be greatly appreciated.

@rirze A fix for the local python 3 issues have been committed. Please pull the master and see if that fixes your issue. https://github.com/HewlettPackard/python-ilorest-library/commit/1b02fad86ebe6a8e681d791fe7838104f2a6d371

@rirze Yes. We are working on a fix now. I will update the issue once it has been addressed. In the meantime, if you need it to work now, can you try running it with the latest Python 2?
