[pywbem-devel] M2Crypto issue & cim_provider2 usage

[Andreas M. <ma...@de...>]

Remi,
On your pywbem upgrade problem:

   If you use the Python package M2CryptoWin32/64 instead of M2Crypto, you
   get a binary installation that does not invoke Swig. This is what the
   setup.py of Pywbem does automatically. However, because we provide
   pywbem as a wheel-type package, its setup.py does not get invoked at
   install time anymore. Instead, its dependencies have been gathered at
   package build time and have been transformed into a data format that is
   part of the wheel package. In that data format, the runtime-dependent
   distinction between M2Crypto and M2CryptoWin32/64 gets lost, and the
   wheel package selects M2Crypto also when being installed on Windows. I
   don't know yet how to improve that situation.

   In the mean time, if you can ensure somehow that M2CryptoWin32/64 is
   installed instead of M2Crypto, your upgrade problem will be solved.

   An alternative would be to go with M2Crypto and to provide the missing
   include files for the Swig processing during M2Crypto installation. The
   specific file showing up as missing is from openssl. See this article:
   http://stackoverflow.com/questions/25110774/how-to-install-m2crypto-on-windows

On the CIMError:

   It seems your provider is a Python provider based upon the cim_provider2
   Python package. That package is no longer part of the pywbem PyPI
   package. We moved it into an "attic" subdirectory, because we were not
   aware of any usage. For now, please copy the file cim_provider2.py from
   the "attic" subdirectory of a pywbem repo clone into the Python
   site-packages directory that is used with that CIMOM. Ensure that you
   can do an import of the "cim_provider2" module. Which CIMOM are you
   using with that?

Hi All

I am using on Windows with Python 2.7  this version of wbem
>>> pywbem.__version__
'0.8.0-dev'

... and I cannot upgrade pywbem due to this error when installing m2crypto:


pip install pywbem --upgrade
...
    SWIG/_m2crypto_wrap.c(6519) : fatal error C1083: Cannot open include
file: 'poll.h': No such file or directory

So here is my problem:

>>> conn = pywbem.WBEMConnection("https://192.168.1.88:5989" ,
('my-user','my-pass') )
>>> lst = conn.EnumerateInstanceNames
(ClassName="CIM_Process",namespace="root/cimv2")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\pywbem\cim_operations.py", line 926,
in EnumerateInstanceNames
    **params)
  File "C:\Python27\lib\site-packages\pywbem\cim_operations.py", line 672,
in imethodcall
    raise CIMError(code, tt[1]['DESCRIPTION'])
pywbem.cim_operations.CIMError: (1, u'CIM_ERR_FAILED: Error initializing
CMPI MI /home/rchateau/TestProviderOpenLMI/tutorial_final/T
UT_UnixProcess.py, the following MI factory function(s) returned an error:
_Generic_Create_InstanceMI, message was: cmpi:Traceback (
most recent call last):<br>  File
"/usr/lib64/python2.7/site-packages/cmpi_pywbem_bindings.py", line 34, in
<module><br>    from pyw
bem.cim_provider2 import ProviderProxy<br>ImportError: No module named
cim_provider2<br>')

With other classes such as LMI_Account or PG_UnixProcess (Which is a
derived class of CIM_Process), it works fine.

Any clue, please ?

Thanks

Remi

PS: Also, still with the same fault command, sometimes it loses a
connection with the message:

EnumerateInstanceNames: entity_host=http://192.168.1.88:5988
nameSpace=root/cimv2 className=CIM_UnixProcess. Caught:(1,
u'CIM_ERR_FAILED: Lost connection with cimprovagt "pyCmpiProvider".')
