[Bug Report] Wiki as submodule

[schorsch13]

Introduction

When adding the wiki of a repo to the repo itself as a submodule, you will get a 404 error in the web UI when clicking on the submodule. This occurs due to the fact that the wiki is no real repo.

Example

Here are two example repositories. One on codeberg and one on try.gitea

• https://try.gitea.io/schorsch/test-wiki-submodule
• https://codeberg.org/moenavigator/moenavigatorengine (the ./doc folder)

Proposal

The wiki has the exact same name as the original repo but with the suffix .wiki. When accessing https://gitea-instace.example/user/repo.wiki just redirect to https://gitea-instance.example/user/repo/wiki

Credits

The bug was discovered by the codeberg user ncc1988. They also suggested the workaround. For further information have a look at the issue on codeberg: https://codeberg.org/Codeberg/Community/issues/217

But this maybe a break for those repositories have suffix .wiki but in fact it's not a wiki of some repositories.

@lunny .wiki has been reserved.
