An _environment source is added that looks in os.environ for values. Using the environment is on by default, but can be shut down by setting `use_env` to False when __call__ is called. The enviroment is inspected before any other sources of config data but the value is used after command line arguments and before config file options. This is done by checking both the command line and config files and then inspecting the location of the result. If it is command_line, we use it. If not, we use the environment value (if any). If there's no environment value, the config file value is used. If checking the command line and config file results in a KeyError, the environment value is used, if set. The names of the environment variables follow the rules described in oslo_config.sources._environment. A new exception has been added: ConfigSourceValueError, this is the superclass of the existing ConfigFileValueError. The code in _do_get has been updated to only use ConfigFileValueError when it is in fact a file from whence a ValueError came. Documentation has been updated and a rlease note created to indicate the new functionality. Change-Id: I3245c40ebdcc96f8e3b2dc0bab3b4aa71d07ad15 |
