[rabbitmq-discuss] Bug in management plugin escaping

[Lionel Cons]

I've found a bug in the way the RabbitMQ plugin handles escaping.

Here is how to reproduce it with RabbitMQ 2.7.1.

I use the web-based management interface to create a user.

I then set the permissions to be everything starting with "test.".
According to http://www.rabbitmq.com/access-control.html, I type in
the relevant field: test\..*

When I press "Set permission", the web interface reports:

Got response code 500 with body
Internal Server Error
The server encountered an error while processing this request:

{error,{error,undef,
              [{xmerl_ucs,from_utf8,[<<"test\\..*">>]},
               {mochijson2,json_encode_string,2},
               {mochijson2,'-json_encode_proplist/2-fun-0-',3},
               {lists,foldl,3},
               {mochijson2,json_encode_proplist,2},
               {mochijson2,'-json_encode_array/2-fun-0-',3},
               {lists,foldl,3},
               {mochijson2,json_encode_array,2}]}}

FWIW, I get the same problem using rabbitmqadmin.

Cheers,
