	[ruby/resolv] Fix confusion of received response message

	This is a follow up for commit 33fb966197f1 ("Remove sender/message_id
	pair after response received in resolv", 2020-09-11).

	As the @senders instance variable is also used for tracking transaction
	ID allocation, simply removing an entry without releasing the ID would
	eventually deplete the ID space and cause
	Resolv::DNS.allocate_request_id to hang.

	It seems the intention of the code was to check that the received DNS
	message is actually the response for the question made within the method
	earlier. Let's have it actually do so.

	Remove sender/message_id pair after response received in resolv

	Once a response for a given DNS request has been received (which
	requires a matching message id), the [sender, message_id] pair
	should be removed from the list of valid senders.  This makes it
	so duplicate responses from the same sender are ignored.

	Fixes [Bug #12838]

Deprecate taint/trust and related methods, and make the methods no-ops

2019-11-17T23:00:25+00:00

This removes the related tests, and puts the related specs behind
version guards.  This affects all code in lib, including some
libraries that may want to support older versions of Ruby.

Fallback to TCP in resolv if UDP bind raises EACCES

Get rid of LoadError with $DEBUG

Make Resolv::DNS#each_name accept Resolv::IPv{4,6} arguments

2019-06-09T03:31:12+00:00

These arguments were previously documented as supported, but not
actually supported.

resolv.rb: remove rangerand

resolv.rb: close socket

2018-03-06T02:48:17+00:00

* lib/resolv.rb (UnconnectedUDP#lazy_initialize): store new
  sockets before binding, so the sockets get closed when the
  requester is closing.

* lib/resolv.rb (ConnectedUDP#lazy_initialize): ditto.

* lib/resolv.rb (UnconnectedUDP#close): synchronize to get rid of
  race condition.

* lib/resolv.rb (ConnectedUDP#close): ditto.

resolv.rb: NUL hosts

2018-01-18T03:09:39+00:00

* lib/resolv.rb (Resolv::Hosts::DefaultFileName): fallback to NUL
  device when Win32::Resolv.get_hosts_path() returned nil, to get
  rid of TypeError in lazy_initialize.
