You need to remove the type-hint from the constructor, and probably add an exception instead where the matching methods are called to ensure that either ``UrlMatcherInterface``, or ``RequestMatcherInterface`` were passed. Alternatively, you could also add such a check to the constructor.

Reverted the changes to UrlMatcher.php.

@niklasf: it looks good now except for the listener constructor (see @schmittjoh suggestion above). Can you fix that and add some unit tests to ensure that everything works as expected? Thanks.

Another solution could be to make the ``RequestMatcherInterface`` extend the ``MatcherInterface`` to keep the typehint in the constructor

---------------------------------------------------------------------------

by fabpot at 2012-05-25T13:52:26Z

I thought about that as well, but that does not make sense.

Well, the RouterInterface extends UrlMatcherInterface anyway (and it should stay this way as it would be a huge BC break) so I guess most people will implement both interfaces when implementing the RquestMatcherInterface

Can you add a note in the CHANGELOG of the component?

@fabpot: Sorry, not sure how: Under 2.1.0 or in a new section? As the first or last entry of the list?

by stof at 2012-05-26T10:20:23Z

@niklasf the new interface should be mentioned in the changelog of the Routing component

Ah ... so there were two pitfalls:

- PHPUnit clones the arguments of mocked functions. So they wouldn't equal.
- createGetResponseEventForUri() disables routing on purpose. So not using that helper, now.

Tests should be passing.
