Test failures with webrick 1.7

[dleidert]

We see the tests in httpclient run into timeouts with webrick 1.7.0. I was able to track it down to this line in lib/httpclient/session.rb:

    799     StatusParseRegexp = %r(\AHTTP/(\d+\.\d+)\s+(\d\d\d)\s*([^\r\n]+)?\r?\n\z)
    800     def parse_header(socket)
    801       ::Timeout.timeout(@receive_timeout, ReceiveTimeoutError) do
    802         initial_line = nil
    803         begin
    804           begin
=>  805             initial_line = socket.gets("\n")
    806             if initial_line.nil?
    807               close
    808               raise KeepAliveDisconnected.new(self)
    809             end
    810           rescue Errno::ECONNABORTED, Errno::ECONNRESET, Errno::EPIPE, IOError

Here it "stalls". The problem is caused by this small change in webrick:

I have just been informed by a colleague that the commit has been reverted in webrick: https://github.com/ruby/webrick/issues/67, but there is not yet a new version of it. So you'll probably try to stay clear of version 1.7.0.

Thanks for noting this! I was running the tests on Ruby 3.0 to test compatibility with that version of Ruby, and the tests pass when I add Webrick 1.6.1 to the Gemfile. So I guess it's compatible with Ruby 3.0 even though it hasn't been updated in a while.

webrick-1.8.0 and webrick-1.8.1 have been released in the meantime.
