As already determined in #2259, it would make sense to start phasing out
gorilla/mux
in all of incus, this PR aims to do just that.Worth noting that
http.ServeMux
does not implement aNotFoundHandler
, but since we already overwriteServeHTTP
, I tried to do a trivial reimplementation of it, which just checks if aHandler
for a given route exists and executes a supplied function if not.Most of the other changes here consist of replacing
mux.Vars(r)[]
withr.PathValue()
. This all builds fine, but I have not extensively tested this yet, which is on my to-do list for the next coming days.
