the errors that can happen in one message. I have separated the message in 2 different messages.
1. When there is a parameter or a literal following the optional parameter.
2. when optional parameter is preceded by a literal other than period which is not allowed.
This change adds a feature needed for aspnet/Mvc#302
There's a new option in routing that allows link-generation to proceed
when the route values cannot be validated. The key scenario for this is
during development of an MVC site. Routing will refuse to generate a link
to actions which don't exists, this is a breaking change from the MVC5
behavior. Setting UseBestEffortLinkGeneration will allow routing to return
a value even when we can't match the action.
This option will remain off by default - setting this to on will impact
link-generation in a bunch of scenarios involving areas where we've
improved the logic for MVC6. If you're considering leaving this on outside
of development scenarios, then make sure to be as explicit with route values
as possible (don't rely on ambient values).
Functional tests to follow up in the MVC repo.
- `DefaultInlineConstraintResolver` has no need of a `IServiceProvider`
nits:
- add doc comments for changed `DefaultInlineConstraintResolver` ctor
- let VS add a dev server port to sample's .kproj
- add debugSettings.json and .vs/ to .gitignore
1. Template parser now allows a parameter to be an optional parameter in a complex segment if
it is the last and only optional parameter and it is followed by a period.
2. Template matcher modified to take into consideration the optional parameter in the complex
segment. Also the period shouldn't be present if the optional parameter is not present
Added OptionalRouteConstraint class to take care of optional inline parameter. It will create the OptionalRouteConstraint for a inline parameter that is optional with real constraint on the parameter as inner constraint of OptionalRouteConstraint.
The properties on TemplateRoute for DataTokens and Defaults are now
readonly. This prevents modifying these collections in a way that
invalidates cached data, or violates thread-safety.
To do the same for constraints, this change includes a substantial refactor
of how we realize inline constraints, and moves the constraint resolver
out of the parsing phase.
This allow creates a builder for the constraint map, that will make it
easier to implement features like optional constraints, and is reusable
for anyone building their own type of routing system.
This is the routing part of the fix. MVC will be updated as well
(attribute routing).
As the graph of routers is traversed, routers add themselves to the
current 'path', which unwinds on a failed path.
This mechanism is opt-in. Whoever adds something needs to remove it as
part of cleanup. If a router in the tree doesn't interact with the
.Routers property, then there are no consequences for those that do.
Additionally, fixing #116 as part of the same change. This means that we
create a nested 'RouteData' and then restore it on the way out. This is
simpler than just dealing with the .Routers property in isolation.
Changed the implementation of route template to merge the existing route data
with the values obtained from parsing the request path with the given template.
Restored original route data values in case the route template data does not match.
