|
|
|
|
The returned list includes all oslo.config options which may be registered
|
|
at runtime by the library.
|
|
|
|
Each element of the list is a tuple. The first element is the name of the
|
|
group under which the list of elements in the second element will be
|
|
registered. A group name of None corresponds to the [DEFAULT] group in
|
|
config files.
|
|
|
|
This function is also discoverable via the 'oslo.messaging' entry point
|
|
under the 'oslo.config.opts' namespace.
|
|
|
|
The purpose of this is to allow tools like the Oslo sample config file
|
|
generator to discover the options exposed to users by this library.
