Make CI green again

[ojab]

httpstat.us switched to HTTPS and returning 301 for plain HTTP and now
there is no X-Powered-By header, use HTTPS + Server header instead.

http.rb >= 5.0.2 expects stream result to be in the proper encoding after httprb/http#653, force encoding in Streamer.

Ok, apparently httpstat.us made some changes a month ago and now there is no Content-Length header.
httpbin.org doesn't return status message, only status code.

I guess we can run https://github.com/aaronpowell/httpstatus/pkgs/container/httpstatus in GHA, but it would complicate local development.

Any hints what's the desired solution? I can try to find another service that could be used or file a bug for https://github.com/aaronpowell/httpstatus, but it's fragile anyway.

Filed an issue aaronpowell/httpstatus#105

httpstat.us issue with missing Content-Length is fixed, also fixed encoding issue in http.rb adapter. CI run in my fork is green https://github.com/ojab/webmock/actions/runs/1696366879

@ojab I wonder why the builds fail on Ruby 3.0.

[ojab]

spec/acceptance/async_http_client/async_http_client_spec.rb hangs 😿
I'm gonna take a look at it this week.

[ojab]

Okay, looks like Async is incompatible with RSpec in ruby >= 3.0.

require 'async'
require 'async/http'

RSpec.describe 'qwe' do
  let(:endpoint) { Async::HTTP::Endpoint.parse('http://www.example.com') }
  let(:protocol) { Async::HTTP::Protocol::HTTP10 }
  let(:requests_count) { 1 }

  subject do
    puts "In subject"
    responses = {}
    Async do |task|
      puts "In Async"
      Async::HTTP::Client.open(endpoint, protocol) do |client|
        puts "In Client"
        requests_count.times do |index|
          response = client.get "/foo#{index}"
          responses[index] = response_to_hash(response)
        end
      end
    end
    responses
  end

  specify do
    puts "Running!"
    expect(subject).not_to be_nil
  end
end

this spec in empty project with Gemfile

# frozen_string_literal: true

source "https://rubygems.org"

# gem "rails"

gem 'async-http'
gem 'rspec'

hangs the same way. async-2.0 switched to fiber scheduler and dropped ruby<3.0 support, so I don't see value in reporting it.

Anyway, not a webmock bug, workarounded by replacing let with let! in the last commit.

[ojab]

And some RSpec changes broken two specs, fixed in the last commit.
CI in my fork is green https://github.com/ojab/webmock/actions/runs/1824337706 with all the changes.

Thank you @ojab
