Matteo Vaccari 5225da7001 expvar: avoid conflict with user-defined "GET /" route. ... With the new routing style in go 1.22, declaring http.Handle("GET /", h) generates a conflict with route "/debug/vars" declared in the expvar package. You get an error such as: panic: pattern "GET /" (registered at ...) conflicts with pattern "/debug/vars" (registered at ...expvar.go:384): GET / matches fewer methods than /debug/vars, but has a more general path pattern This patch prevents that error. Adding GET is correct because no other method makes sense with /debug/vars. We preserve the traditional behaviour when GODEBUG=httpmuxgo121=1 is specified.
