[Bug 1869929] Re: RuntimeError: maximum recursion depth exceeded while calling a Python object
Think this isn't a bug but was related to SELinux. This issue happend
when I upgraded nova on our compute node and then this occured. So I
removed the @db.select_db_reader_mode decorator usage in
nova/objects/service.py to make it start.
I then proceeded to upgrade Neutron and Ceilometer on the compute nodes,
Neutron requires the following SELinux packages to be updated in order
for it to work:
libselinux libselinux-python libselinux-utils selinux-policy selinux-
policy-targeted
When I upgraded that, neutron and ceilometer I didn't bother testing again.
I removed the commented decorators now and restart nova-compute and it worked.
This is the install log:

The possibility of any of the additional packages after nova-compute
there fixed it is very low.
The only thing I did manually except for that was to upgrade the SELinux
packages mentioned above because that's required by Neutron.

Title:
RuntimeError: maximum recursion depth exceeded while calling a Python
object
Status in OpenStack Compute (nova):
Invalid
Status in oslo.config:
Invalid
Bug description:
When testing upgrading nova packages from Rocky to Train the following
issue occurs:
versions:
oslo.config 6.11.2
oslo.concurrency 3.30.0
oslo.versionedobjects 1.36.1
oslo.db 5.0.2
oslo.config 6.11.2
oslo.cache 1.37.0
Happens here https://github.com/openstack/oslo.db/blob/5.0.2/oslo_db/api.py#L304
where it register_opts for options.database_opts
This cmp operation:
https://github.com/openstack/oslo.config/blob/6.11.2/oslo_config/cfg.py#L363
If I edit above cmp operation and add print statements before like this:
if opt.dest in opts:
print('left: %s' % str(opts[opt.dest]['opt'].name))
print('right: %s' % str(opt.name))
if opts[opt.dest]['opt'] != opt:
raise DuplicateOptError(opt.name)
It stops here:
$ nova-compute --help
left: sqlite_synchronous
right: sqlite_synchronous
Traceback (most recent call last):
....same exception
