Unreleased Release Notes

10.7.0

New Features

• There is now new sample_min and sample_max attributes to the int configuration object. They may be use to replace the min and max values when generating the configuration file with oslo-config-generator. For example, if one wants max=processutils.get_worker_count(), it is desirable to set a sample_max value (ie: sample_max=’<WORKER_COUNT>’) to avoid that the number of CPU of the builder machine leaks in the generated configuration file.

10.6.0

New Features

• ConfigOpts instances can now export and import a serialized state and use that state for pickle serialization. This allows configuration state to be passed to multiprocessing workers that use the spawn start method. The serialized state preserves registered options and groups, parsed command-line and config-file values, defaults, overrides, and setup metadata.

  Process-local helpers such as argparse parsers, caches, extension managers, mutation hooks, and environment drivers are intentionally excluded from the serialized state. Loaded configuration source objects, typically created through the config_source option or --config_source argument, are rejected with ConfigOptsSerializationError instead of being silently dropped.

10.5.0

Upgrade Notes

• Support for Python 3.10 has been removed. Now the minimum python version supported is 3.11.

Deprecation Notes

• The oslo_config.version module and associated objects has been deprecated for removal. Prefer use of importlib.metadata to inspect version information for installed packages.
