error: BadResource: Bad resource ID

I'm writing tests for https://github.com/deno-libs/tinyhttp/pull/9.

import { describe, expect, it, run } from 'https://deno.land/x/tincan@1.0.1/mod.ts'
import { App } from '../../app.ts'

describe('Request properties', () => {
  it.only('should have default HTTP Request properties', async () => {
    const app = new App()
    app.get('/', (req, res) => {
      res.json({ url: req.url })
    })
    const listener = Deno.listen({ port: 8080, hostname: 'localhost' })

    setTimeout(() => {
      fetch(`http://localhost:8080`).then((res) => res.json()).then((json) => {
        expect(json).toEqual({ url: `http://localhost:8080/` }) 
      })
    }, 0)

    const conn = await listener.accept()
    const requests = Deno.serveHttp(conn)
    const { request, respondWith } = (await requests.nextRequest())!
    const response = await app.handler(request, conn)
    if (response) {
      respondWith(response)
      // Deno.close(conn.rid)
      
      listener.close()
    }
  })
})

import { describe, expect, it, run } from 'https://deno.land/x/tincan@1.0.1/mod.ts'
import { App } from '../../app.ts'

describe('Request properties', () => {
  it.only('should have default HTTP Request properties', async () => {
    const app = new App()
    app.get('/', (req, res) => {
      res.json({ url: req.url })
    })
    const listener = Deno.listen({ port: 8080, hostname: 'localhost' })

    setTimeout(() => {
      fetch(`http://localhost:8080`).then((res) => res.json()).then((json) => {
        expect(json).toEqual({ url: `http://localhost:8080/` }) 
      })
    }, 0)

    const conn = await listener.accept()
    const requests = Deno.serveHttp(conn)
    const { request, respondWith } = (await requests.nextRequest())!
    const response = await app.handler(request, conn)
    if (response) {
      respondWith(response)
      // Deno.close(conn.rid)
      
      listener.close()
    }
  })
})

When running this test I get either this:

Request properties > should have default HTTP Request properties => https://deno.land/x/tincan@1.0.1/src/runner.ts:166:10

or this, if I uncomment that line:

what I'm trying to do is to close the server once a request has been done

AapoAlas•2y ago

conn.close() would be the normal API to close the connection, I think.

v1rtlOP•2y ago

conn.close emits the same error as Deno.close(conn.rid)

AapoAlas•2y ago

Hmm... Maybe await the respondWith ... Not sure though.

v1rtlOP•2y ago

I fixed with Deno.close(conn.rid + 1)... weird but it works

AapoAlas•2y ago

That sounds absolutely dirty, unsafe and unsound 😄 Not to kick you down of course, just that calculating another rid from one is probably really easy to break semi-randomly.

v1rtlOP•2y ago

well nothing else worked lol

AapoAlas•2y ago

Yeah.
