> Router ID text name is not restricted
> -------------------------------------
>
> Key: DISPATCH-1553
> URL: https://issues.apache.org/jira/browse/DISPATCH-1553
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Router Node
> Affects Versions: 1.10.0
> Reporter: Charles E. Rolke
> Priority: Major
>
> The router allows unicode, punctuation, and escaped characters in the Router
> ID attribute string. It is possible to construct an ID that becomes
> python-escaped when displayed in qdstat and log files. The output is
> confusing to read and hard to consume with automated tools since the strings
> are different in a) the config file, b) over the wire between routers, and c)
> in qdstat and logs.
> The proposal here is to limit the characters allowed in a Router ID to the
> following printable ASCII characters:
> * A-Z - uppercase letters
> * a-z - lowercase letters
> * 0-9 - numeric digits
> * '-' - hyphen
> * '.' - period
