Bug #10054: Net::HTTPGenericRequest sets host even if it was set before by user

* Author: Dmitriy Semenyuk

# there is SSH tunnel that forwards 127.0.0.1:9293 to google.com:80
request = Net::HTTP::Post.new(URI("http://127.0.0.1:9293")).tap do |req|
req.form_data = {q: "ruby"}
req["Host"] = "google.com"
end
~~~
This code ignores host that was already set (it uses "#{host}:#{uri}"):
~~~
Net::HTTP.start(uri.hostname, uri.port) { |http| http.request(request) }
~~~
I encountered this bug when tried to connect to remote server using SSH tunnel (/etc/hosts isn't available to edit).
Resolution:
https://bugs.ruby-lang.org/projects/ruby-trunk/repository/entry/lib/net/http/generic_request.rb line 119
~~~
def exec(sock, ver, path) #:nodoc: internal use only
- if @uri
+ if @uri && !self['host']
if @uri.port == @uri.default_port
