I think it's fine to just mention it in the changelog. Alternatively, maybe we could detect such dead routes at compile time and drop them to keep the same behavior, emitting a deprecation warning? Then we drop that extra code for 2.0. |
This pull request compiles routes by verb, which speeds up
compilation times for large routes. This is done by making
sure `match/forward` statements always come last.
Therefore, this pull request changes the semantics of *dead
routes*. If you had this code:
match "/foo"
get "/foo"
The second route would never be matched but it is now as part
of this pull request. However, `get "/foo"` should not be there
in the first place. So the routes should either be rearranged
or removed anyway.

However, note that `get "/foo"` should not exist in the first place: it should be either removed or moved first. We recommend checking for any `match :*` in your router and moving them to the end of the file. |

This pull request groups compiled routes by verb, which speeds up compilation times for large routers up to 3x. A side-effect is that
match/forwardroutes are always matched last.Therefore, this pull request changes the semantics of dead routes. If you had this code:
The second route would never be matched but it is now as part of this pull request. However,
get "/foo"should not be there in the first place. It is effectively a dead route.Currently WIP. We should either document this pitfall or put this change behind an option. I am fine with documenting this in the CHANGELOG as the code above should either not exist or be correct anyway.
