Bug in pattern matching for registration?

[Steve Ditlinger]

Two registrations:

"get.flights.." with wildcard matching

"get.flight" with prefix matching

A call to "get.flights.chicago.boston" matches the "get.flight" registration resulting in that RPC being called

This should not be the case, correct?

I change the second registration to:

"get.flight." with wildcard matching

Now a call to get.flights.chicago.boston matches the "get.flights.." registration as intended and expected


Shouldn't prefix matching require a "." in the RPC call at the point where the prefix ends?  Or should "get.flightABCDE" also match "get.flight" with prefix matching?

Thanks,
Steve

Hi Steve,

this is expected behavior. Registrations are matched in a hierarchy: exact, prefix, wildcard. In your example "get.flight" with "prefix" matching takes precedence over any wildcard registration (see http://crossbar.io/docs/Pattern-Based-Registrations/).

Regards,

Alex

Matching method hierarchy aside, I must admit that I, like Steve here, thought that the prefix had to cover entire components of the URI for it to be considered a prefix match at all.

I guess I was confused by this page  http://crossbar.io/docs/Pattern-Based-Registrations/

where it is explained that, with prefix matching, com.myapp.manage will match

com.myapp.manage.add, com.myapp.manage.store, com.myapp.manage.retrieve, and com.myapp.manage.ship

Left unsaid is that it will also match com.myapp.manager and com.myapp.manages

This makes sense, as it creates a greater distinction between prefix and wildcard matching, i.e.

"com.myapp.manage" registration with prefix is different from "com.myapp.manage." registration with wildcard. The page at the link above should be modified to emphasize that point.
