The old code is unnecessarily complex, and has many misuses. Old code "wraps" a lot, wrap wrap wrap, it's difficult to understand which kind of handler is used. The new code uses a general approach, we do not need to write all kinds of handlers into the "wrapper", do not need to wrap them again and again. New code, there are only 2 concepts: 1. HandlerProvider: `func (h any) (handlerProvider func (next) http.Handler)`, it can be used as middleware 2. Use HandlerProvider to get the final HandlerFunc, and use it for `r.Get()` And we can decouple the route package from context package (see the TODO). # FAQ ## Is `reflect` safe? Yes, all handlers are checked during startup, see the `preCheckHandler` comment. If any handler is wrong, developers could know it in the first time. ## Does `reflect` affect performance? No. https://github.com/go-gitea/gitea/pull/24080#discussion_r1164825901 1. This reflect code only runs for each web handler call, handler is far more slower: 10ms-50ms 2. The reflect is pretty fast (comparing to other code): 0.000265ms 3. XORM has more reflect operations already
