Can't upgrade request to websocket

I want to use a websocket in one of my middlewares. But I keep getting an error saying I can't upgrade my connection:

[uncaught application error]: TypeError - Invalid Header: 'upgrade' header must contain 'websocket'

[uncaught application error]: TypeError - Invalid Header: 'upgrade' header must contain 'websocket'

I've googled this error but only find old results relating this error to the version of deno or oak lib where I run the latest deno (1.37.2) and oak (12.6.1).

import {Application,Router} from 'https://deno.land/x/oak@v12.6.1/mod.ts'

function RefreshMiddleware() {
  return async (ctx,next) => {
    console.log('url',ctx.request.url.href)
    if (ctx.request.url.href.endsWith("/refresh")) {
      console.log(ctx.isUpgradable);
      console.log(ctx.request.headers.get("connection"));
      const socket = ctx.upgrade()
    } else next()
  }
}

const app = new Application()
app.addEventListener("error", e => console.error(e.error))

// Logger
app.use(async (ctx, next) => {
  const start = Date.now()
  await next()
  console.log(`${ctx.request.method} ${ctx.request.url} - ${Date.now() - start}ms`)
})
app.use(RefreshMiddleware())
app.use((ctx) => {ctx.response.body = "Hello World!"})

await app.listen({port: 8000})

BDD with async tests

I'd like to run some tests that all call the same helper function that wraps the bdd it function. Something like this:

describe('why u no work?', async ()=>{
  const test = async (s) => {let r = await Promise.resolve(0); it(s, ()=>assertEquals(0,r))}
  await test('a')
  await test('b')
  await test('c')
})

describe('why u no work?', async ()=>{
  const test = async (s) => {let r = await Promise.resolve(0); it(s, ()=>assertEquals(0,r))}
  await test('a')
  await test('b')
  await test('c')
})

It works with a non-async version but I'd like to know how to do this in a async way.

Read CSV files inside zip file using the web streams API

I need to read a number of csv files inside a zip file. The basic example I've got working so far is the following:

import {BlobReader,ZipReader,ZipWriter} from 'https://deno.land/x/zipjs/index.js'
import {readCSV} from 'https://deno.land/x/csv/mod.ts'
import {CsvParseStream} from 'https://deno.land/std@0.201.0/csv/mod.ts'

const srcFile = await Deno.open('/data.zip')
const zipReader = new ZipReader(srcFile)
for (let entry of (await zipReader.getEntries())) {
  console.log('filename ', entry.filename)
  let csvStream = new CsvParseStream({skipFirstRow:false,columns:undefined})
  if (entry.filename.startsWith('code')) {
    await entry.getData(csvStream.writable)
    for await (const chunk of csvStream.readable) {
      console.log(chunk)
    }
  }
}

import {BlobReader,ZipReader,ZipWriter} from 'https://deno.land/x/zipjs/index.js'
import {readCSV} from 'https://deno.land/x/csv/mod.ts'
import {CsvParseStream} from 'https://deno.land/std@0.201.0/csv/mod.ts'

const srcFile = await Deno.open('/data.zip')
const zipReader = new ZipReader(srcFile)
for (let entry of (await zipReader.getEntries())) {
  console.log('filename ', entry.filename)
  let csvStream = new CsvParseStream({skipFirstRow:false,columns:undefined})
  if (entry.filename.startsWith('code')) {
    await entry.getData(csvStream.writable)
    for await (const chunk of csvStream.readable) {
      console.log(chunk)
    }
  }
}

The problem is that the chunk is some weird array of strings of numbers and not the row I would expect.

[ "34",  "67", "97", ...1356838 more items

[ "34",  "67", "97", ...1356838 more items

Any help would be welcome.

Sanitize multiple test steps

Is it possible to sanitize multiple steps inside of one test. I want to test my DB with somthing like this:

test('db', {permissions:{net:true,env:true},sanitizeOps:false,sanitizeResources:false}, async t=>{
    await testDB(async sql => {
      assertOk(await ddl(sql))
      await sql`insert into task values ${sql(task)}`
      t.step('popTask', async ()=>assertEquals((await popTask(sql)).ok[0], task))
      t.step('upsertFiling', async ()=>assertOk(async()=>await upsertFiling(sql, {id:1})))
    })
  })

test('db', {permissions:{net:true,env:true},sanitizeOps:false,sanitizeResources:false}, async t=>{
    await testDB(async sql => {
      assertOk(await ddl(sql))
      await sql`insert into task values ${sql(task)}`
      t.step('popTask', async ()=>assertEquals((await popTask(sql)).ok[0], task))
      t.step('upsertFiling', async ()=>assertOk(async()=>await upsertFiling(sql, {id:1})))
    })
  })

But I get this error Started test step while another test step with sanitizers was running:

Deno hangs on error

Why does Deno hang when XML.parse throws an error?

let text = '<xml><xbrli:xbrl><hi>Hello</hi></xbrli:xbrl></xml>'
import * as XML from "https://deno.land/x/xml/mod.ts"

let parseXml = text => {
  try{
    return XML.parse(text)
  }catch(e){
    return null
  }
};

parseXml(text)
console.log('ok')
try{
  parseXml('fail')
}catch(e){
  console.log(e)
}

let text = '<xml><xbrli:xbrl><hi>Hello</hi></xbrli:xbrl></xml>'
import * as XML from "https://deno.land/x/xml/mod.ts"

let parseXml = text => {
  try{
    return XML.parse(text)
  }catch(e){
    return null
  }
};

parseXml(text)
console.log('ok')
try{
  parseXml('fail')
}catch(e){
  console.log(e)
}
