Oslo.config cfg.py throws deprecation warning

[Doug Chivers]

I get a deprecation message when using oslo config:

$ .venv/bin/pecan serve config_pecan.py
2015-01-16 12:14:45,379 WARNI [py.warnings][21870/MainThread]
./.venv/lib/python2.7/site-packages/oslo_config/cfg.py:333: DeprecationWarning: The oslo namespace package is deprecated. Please use oslo_config instead.
  from oslo.config import iniparser

I am importing oslo config as follows:

from oslo_config import cfg

This is the latest availible oslo_config, installed using pip.

Can you provide more information about the ./.venv/lib/python2.7/site-package/ and ./.venv/local/lib/python2.7/site-package?

[Longjie_Cao (grasson1101)]

My test for pecan can work, please forgive me if I am not doing the same thing as you did:
virtualenv oslo-app
cd oslo-app
source bin/activate
pip install pecan
pip install oslo.config
pecan create pecanrest
cd pecanrest
python setup.py develop
pecan serve config.py

The result is as:
(oslo-app)root@ubuntu2:~/workdir/project/oslo-app/pecanrest# pecan serve config.py
Starting server in PID 15632
serving on 0.0.0.0:8080, view at http://127.0.0.1:8080

The reason this appeared in pecan is because I have debug enabled, which causes deprecation warnings to be shown. This can be demonstrated as follows.

Create a new virtual env and install oslo config:

$ virtualenv oslotest
$ . oslotest/bin/activate
$ pip install oslo.config

Configure python to show deprecation warnings:

$ python
>>> import logging, warnings
>>> from logging import captureWarnings
>>> logging.basicConfig()
>>> captureWarnings(True)
>>> warnings.simplefilter("default", DeprecationWarning)

Test a deprecation warning:

>>> warnings.warn('hello world',DeprecationWarning)
WARNING:py.warnings:__main__:1: DeprecationWarning: hello world

Import oslo.config:

>>> import oslo.config
WARNING:py.warnings:__main__:1: DeprecationWarning: The oslo namespace package is deprecated. Please use oslo_config instead.

please give a solution for my glance installation (image service installation) under ubuntu 14.04 lts openstack

When I am executing the command
      su -s /bin/sh -c "glance-manage db_sync" glance

Traceback (most recent call last):
  File "/usr/bin/glance-manage", line 6, in <module>
    from glance.cmd.manage import main
  File "/usr/lib/python2.7/dist-packages/glance/cmd/manage.py", line 41, in <module>
    from oslo.config import cfg
ImportError: No module named config

So I tried the command

$ python

and tried to execute the instruction
>>> import oslo.config
The system gives the error as given below

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named config

So please give a solution for this problem Please ......................

@sumesh stupid question, you do have oslo.config installed?

$ pip install oslo.config
