NDB: Route is not found when using destination with prefixlen

[mawiegand]

Getting a route via ndb.routes[{"dst": "10.0.4.0/24"}] seems to be no longer working:

>>> ndb.routes[{"dst": "10.0.4.0/24"}]
{'dst': '10.0.4.0/24'}
{'dst': '10.0.4.0/24', 'target': 'localhost'}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/pyroute2/ndb/auth_manager.py", line 69, in guard
    return f(obj, *argv, **kwarg)
  File "/usr/lib/python3/dist-packages/pyroute2/ndb/main.py", line 551, in __getitem__
    ret = self.template(key, table)
  File "/usr/lib/python3/dist-packages/pyroute2/ndb/main.py", line 392, in template
    auth_managers=self.auth_managers)
  File "/usr/lib/python3/dist-packages/pyroute2/ndb/objects/route.py", line 525, in __init__
    super(Route, self).__init__(*argv, **kwarg)
  File "/usr/lib/python3/dist-packages/pyroute2/ndb/objects/__init__.py", line 327, in __init__
    raise KeyError('object does not exists')
KeyError: 'object does not exists'

The same applies to ndb.routes.get({"dst": "10.0.4.0/24"}).

When using

>>> ndb.routes["10.0.4.0/24"]
{'dst': '10.0.4.0', 'dst_len': 24, 'target': 'localhost'}
{'multipath': [], 'metrics': {}, 'dst': '10.0.4.0', 'dst_len': 24, 'target': 'localhost', 'table': 254, 'tflags': 0, 'family': 2, 'tos': 0, 'scope': 253, 'oif': 4, 'priority': 0, 'via': '', 'newdst': '', 'src_len': 0, 'proto': 2, 'type': 1, 'flags': 0, 'src': None, 'iif': None, 'gateway': None, 'prefsrc': '10.0.4.15', 'protoinfo': None, 'flow': None, 'mark': None, 'pref': None, 'encap_type': None, 'route_id': None, 'gc_mark': None}

the route is found.

Tested with pyroute2 version 0.5.19 and 0.6.2.

Would be nice if this could be fixed and maybe patched for version 0.5 which we are using. 🙂

Thanks!

Thanks, fixing!

Thank you! 6aa174e seems to fix it. 😄
Any plans for a new release in the near future? Otherwise we will patch it on our own. 🙂
