[Bug] RSS URI Access Encoding Issues

[OdinVex]

Description

Attempting to access the RSS feed of a user that has a period in their name results in a 404. Encoding the URI with %2e works. The problem exists on try.gitea.io and my own self-hosted Gitea, as well as other publicly-facing Gitea instances.

Gitea Version

1.17.2

Can you reproduce the bug on the Gitea demo site?

Yes

How are you running Gitea?

Database

I looked a bit into this. This line is weird:

gitea/services/context/user.go

Line 40 in 3fef47b

username := ctx.Params(":username")

If the user has a dot in their name, it returns username.rss instead of username. Perhaps, a maintainer could say why this happens?

Got this problem while adding a new package type. I found the issue but I'm not sure what could be a solution. I have created an issue: go-chi/chi#781

Definitely seems a 'same' situation. In your case, greedy seems best, assuming there is always a .extension.
