Route constraints invoked for paths which do not use the route constraint

[onionhammer]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Using a {parameter} in one route and a {*catchall} in another route causes a RouteHandlers to be invoked unrelated requests

Example:

/tiles/{**path} 
/{partner:my_route_constraint}/{form}.js

the my_route_constraint will be invoked with "tiles" as the routeKey value of partner even though the path is not using that constraint, and is more specific (starts with /tiles/) for certain requests

example:

GET /tiles/one_segment <-- this hits the route constraint
GET /tiles/one_segment/two_second <-- this does not hit the route constraint

Expected Behavior

If you specify a prefixed route, it should not hit a route constraint?

@onionhammer thanks for contacting us.

This is by design. Routing evaluates the current path against all potential matches as a first step and then applies matcher policies and ordering to get a final result.
/tiles/{**path} might not match because it has an HTTP POST constraint and, in that case, /tiles/sample.js will still match and can't be discarded.

Why was the choice made to not just route to a more specific path?
