I think the current neutron implementation could benefit from some refactoring.
It is however already marked as production ready and used, so some of the
changes might break user code. So this is a big problem, obviously - I need
some help figuring out if it is worth it.
Other upcoming neutron work is of course adding the extension code from
previous PRs that were not merged completely (such as [1]), as well as the rest
of the extensions. There are quite a few.
Things currently already merged that I am considering for changes:
Remove Reference and ReferenceWithName [2];
These will be refactored by moving the name/id/tenant_id fields to the
respective classes (such as Network or Port in the examples I use here).
This is needed for the next step.
Ensure class inheritance follows, for example,
Network extends CreateNetwork
where CreateNetwork or List<CreateNetwork> would be the parameter object in
NetworkApi.create (instead of CreateNetworkOptions) and Network, again, will be
the result.
In this example Network extends CreateNetwork to add fields such as id,
tenant_id, name (these were mentioned above) as well as *other* fields that the
service returns.
This change might also improve on an issue mentioned here [3]
The two steps above will help move validation to the domain objects
constructors, and hopefully remove the need to use explicit JSON binders and
options code.
Also (I could be missing something) I don't see the need for BulkPort and
BulkNetwork - these should be similar enough to the refactored CreateNetwork
and CreatePort.
Example:
Network Create json request:
{
"network":
{
"name": "sample_network",
"admin_state_up": false
}
}
bulk network create:
{
"networks":[
{
"name":"sample_network_1",
"admin_state_up":false
},
{
"name":"sample_network_2",
"admin_state_up":false
}
]
}
The questions is: is this worth it? The code seems functional enough. Thanks!
