* only keep one hash of named routesAaron Patterson2015-08-141-1/+1
| | | | | The outer router object already keeps a hash of named routes, so we should just use that.

* Remove (another) array allocationschneems2015-07-301-5/+14
| | | | | | We don't always need an array when generating a url with the formatter. We can be lazy about allocating the `missing_keys` array. This saves us: 35,606 bytes and 889 objects per request
* Remove array allocationschneems2015-07-301-2/+2
| | | | | | THe only reason we were allocating an array is to get the "missing_keys" variable in scope of the error message generator. Guess what? Arrays kinda take up a lot of memory, so by replacing that with a nil, we save: 35,303 bytes and 886 objects per request
* Avoid calling to_s on nil in journey/formatterschneems2015-07-301-2/+2
| | | | | | | | When `defaults[key]` in `generate` in the journey formatter is called, it often returns a `nil` when we call `to_s` on a nil, it allocates an empty string. We can skip this check when the default value is nil. This change buys us 35,431 bytes of memory and 887 fewer objects per request. Thanks to @matthewd for help with the readability
* Speed up journey missing_keysschneems2015-07-291-3/+15
| | | | | | | | Most routes have a `route.path.requirements[key]` of `/[-_.a-zA-Z0-9]+\/[-_.a-zA-Z0-9]+/` yet every time this method is called a new regex is generated on the fly with `/\A#{DEFAULT_INPUT}\Z/`. OBJECT ALLOCATIONS BLERG! This change uses a special module that implements `===` so it can be used in a case statement to pull out the default input. When this happens, we use a pre-generated regex. This change buys us 1,643,465 bytes of memory and 7,990 fewer objects per request.
* Speed up journey extract_parameterized_partsschneems2015-07-291-2/+3
| | | | | | | | Micro optimization: `reverse.drop_while` is slower than `reverse_each.drop_while`. This doesn't save any object allocations. Second, `keys_to_keep` is typically a very small array. The operation `parameterized_parts.keys - keys_to_keep` actually allocates two arrays. It is quicker (I benchmarked) to iterate over each and check inclusion in array manually. This change buys us 1774 fewer objects per request
* sort_by instead of sortYang Bo2015-04-081-1/+1
| | | | | | it is avoid sort errot within different and mixed keys. used `sort_by` + `block` to list parameter by keys. keep minimum changes
* Remove deprecated option `use_route` in controller testsRafael Mendonça França2015-01-041-15/+0

* Don't show the warning if we're already raising the error anywayGodfrey Chan2014-11-231-8/+13
| | | | | | | | | If the route set is empty, or if none of the routes matches with a score > 0, there is no point showing the deprecation message because we are already be raising the `ActionController::UrlGenerationError` mentioned in the warning. In this case it is the expected behavior and the user wouldn't have to take any actions.
* Deprecate passing an invalid name to `Formatter#generate`Godfrey Chan2014-11-231-0/+10
| | | | | | | | The internal tests that (incorrectly) relied on this were already fixed in 938d130. However, we cannot simply fix this bug because the guides prior to b7b9e92 recommended a workaround that relies on this buggy behavior. Reference #17453

* `recall` should be `path_parameters`, also make it requiredAaron Patterson2014-07-171-3/+3
| | | | | | | | "recall" is a terrible name. This variable contains the parameters that we got from the path (e.g. for "/posts/1" it has :controller => "posts", :id => "1"). Since it contains the parameters we got from the path, "path_parameters" is a better name. We always pass path_parameters to `generate`, so lets make it required.
* Remove AD::Journey::Formatter#verify_required_parts!Viktar Basharymau2014-05-231-5/+0
| | | | | Nobody uses this private method, maybe it is a leftover from some old refactoring. Let's delete it.

* / Use `break` instead of `next` in AD::Journey::Formatter#match_routeViktar Basharymau2014-05-221-1/+1
|/ | | | | | The array is sorted in descending order, so there is no point in iterating further if we met a negative item - all the rest will be negative too.

* Show full route constraints in error messageAndrew White2014-01-051-2/+2
| | | | | | | | When an optimized helper fails to generate, show the full route constraints in the error message. Previously it would only show the contraints that were required as part of the path. Fixes #13592
* Skip Rack applications and redirects when generating urlsAndrew White2013-07-161-1/+5
| | | | | | | | | | When generating an unnamed url (i.e. using `url_for` with an options hash) we should skip anything other than standard Rails routes otherwise it will match the first mounted application or redirect and generate a url with query parameters rather than raising an error if the options hash doesn't match any defined routes. Fixes #8018

| | | | It'd be a nice convention to mark the unused variables like this, now that Ruby 2 will issue no warnings for such vars being unused.
* Raise correct exception now Journey is integrated.Andrew White2013-01-151-1/+6
| | | | | | | Now that Journey has been integrated into ActionDispatch we can raise the exception ActionController::UrlGenerationError directly rather than raising the internal Journey::Router::RoutingError and then have ActionDispatch::Routing::RouteSet#generate re-raise the exception.

Move the Journey code underneath the ActionDispatch namespace so that we don't pollute the global namespace with names that may be used for models. Fixes rails/journey#49.
