determining oslo_config_project changed in commit f8c150a9cc9b407b2df87244daf3342177260e90

[Alfredo Moralejo]

I'm installing aodh from master repo. I'm using following configuration for aodh.conf:

[DEFAULT]
debug = True
log_dir = /var/log/aodh
rpc_backend = rabbit

[oslo_messaging_notifications]
topics = notifications

[oslo_policy]
policy_file = /etc/aodh/policy.json

[service_credentials]
auth_url = http://localhost:5000/
region_name = RegionOne
project_name = services
password = 470ba4223ca94df3
project_domain_id = default
user_domain_id = default
username = aodh
auth_type = password

[oslo_messaging_rabbit]
rabbit_host = 127.0.0.1
rabbit_port = 5672
rabbit_use_ssl = True
rabbit_userid = guest
rabbit_password = guest

[keystone_authtoken]
auth_uri = http://127.0.0.1:5000
project_domain_name = Default
project_name = services
user_domain_name = Default
password = 470ba4223ca94df3
username = aodh
auth_url = http://127.0.0.1:35357
auth_type = password

[database]
connection = mongodb://192.168.121.96:27017/aodh

[api]
pecan_debug = False

When i try to list alarms (or any other api call), i get following error from cli:

# aodh alarm list
Traceback (most recent call last):
  File "/usr/lib64/python2.7/logging/__init__.py", line 851, in emit
    msg = self.format(record)

    return fmt.format(record)
  File "/usr/lib64/python2.7/logging/__init__.py", line 464, in format
    record.message = record.getMessage()
  File "/usr/lib64/python2.7/logging/__init__.py", line 324, in getMessage
    msg = str(self.msg)
  File "/usr/lib/python2.7/site-packages/aodhclient/exceptions.py", line 32, in __str__
    formatted_string = "%s (HTTP %s)" % (self.message, self.http_status)
AttributeError: 'ClientException' object has no attribute 'http_status'
Logged from file app.py, line 351

And i see following messages in apache error log:

Note that it's trying to connect to https://127.0.0.1:35357 while i've configured http://127.0.0.1:35357.

If i revert keystonemiddleware to a commit before https://github.com/openstack/keystonemiddleware/commit/f8c150a9cc9b407b2df87244daf3342177260e90, it works fine.

For example using, https://github.com/openstack/keystonemiddleware/commit/20b4a87e874361d6e28076b994ec06d472dfb0b3:

# aodh alarm list
+--------------------------------------+-----------+--------+-------------------+----------+---------+
| alarm_id | type | name | state | severity | enabled |
+--------------------------------------+-----------+--------+-------------------+----------+---------+
| f2d98900-1298-49af-ab86-0d41deea90f6 | threshold | alarm1 | insufficient data | low | True |
+--------------------------------------+-----------+--------+-------------------+----------+---------+

    Fix an issue with oslo_config_project paste config

    When oslo_config_project is specified in the paste config, we need to
    lookup the configuration file properly. Commit
    f8c150a9cc9b407b2df87244daf3342177260e90 changed the way we looked up
    for the default config files, and passed an empty list instead of None,
    which means that no look were done anymore. This restores the previous
    behavior.
