How to make openapi server implementation revisable?

[schlichtanders]

Hi there, I cannot get Revise work together with OpenAPI.jl generated code and corresponding handler implementation.
Is this is just not supported? (Or may I just be confused and it works for others seamlessly?)

Revise should work, but it needs you to use invokelatest on your side. Revise does update your handler. The problem is the running server uses the method version that the server task started with. HTTP.jl 1.x hid this by calling every handler through Base.invokelatest whereas HTTP.jl 2.x, which OpenAPI.jl 1.x uses, does not.

The right way to do it now it to wrap the generated handlers with Base.invokelatest for register!. It is not the default anymore because Base.invokelatest cannot be compiled with Julia's --trim option, and we want generated servers to stay usable there.

using Revise
includet("Handlers.jl")
include("ExampleServer.jl")

router = HTTP.Router()
ExampleServer.register!(router, Handlers;
    middleware = h -> (request -> Base.invokelatest(h, request)))
server = HTTP.serve!(router, "127.0.0.1", 8080)
