Finally solved, I had to disable the `--threads:on` switch and mark procs with
`gcsafe` and it works with `--mm:orc` and without. It's single threaded but I
for my needs it's enough.
Just wonder why compiler that proc is GC safe, and requires explicit proc
annotation with `.gcsafe.`.
The working code, works with both `nim r play.nim` and `nim r --mm:orc play.nim`
import std/[httpcore, asynchttpserver, asyncnet, tables, asyncdispatch,
locks]
type Session* = ref object
id*: string
count*: int
var sessions: Table[string, Session]
proc http_handler(req: Request): Future[void] {.async, gcsafe.} =
let id = "1"
if id notin sessions:
sessions[id] = Session(id: id)
let session = sessions[id]
await respond(req, Http200, $session.count)
proc background_processing(_: AsyncFD): bool {.gcsafe.} =
for _, session in sessions:
session.count += 1
var server = new_async_http_server()
async_check serve(server, Port(5000), http_handler, "localhost")
add_timer(1000, false, background_processing)
run_forever()
Run
