Hi,

I found edge case where making http request to one of the remote servers can raise Zlib::BufError.The case is about blank body returned by a server for 204 No Content together with header Content-Encoding: gzip .

Can be reproduced this way:

require 'socket'
server = TCPServer.new 8000
loop do

client = server.accept
client.puts <<-EOT
HTTP/1.1 204 No Content
Content-Encoding: gzip
Content-Type: application/json;charset=utf-8

EOT
client.close
end

Call like:

HTTP.use(:auto_inflate, logging: { logger: Logger.new(STDOUT) }).get('http://0.0.0.0:8000')

raise an error ... /gems/http-5.0.0.pre3/lib/http/response/inflater.rb:19:in 'finish': buffer error (Zlib::BufError).
