	resolv.rb: close socket

	* 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.

	[ruby-core:85901] [Bug #14571]

resolv.rb: byte buffer

2017-01-14T02:26:49+00:00

* lib/resolv.rb (Resolv::DNS::Message::MessageDecoder): treat the
  data as a byte buffer.

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57326 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

Made #decode_rdata client to catch errors

2017-01-14T02:26:48+00:00

* lib/resolv.rb (Resolv::DNS::Message::MessageDecoder#get_rr):
  re-raise an exception from decode_rdata as DecodeError, so it
  can report them to the top in more informative way.  It was not
  reflecting on errors of data and thus breaking.  Client code
  expects `DecodeError` and knows how to handle broken messages.

resolv: use safe navigation operator to avoid extra hash lookups

2016-11-23T23:57:30+00:00

@addr2name is a private Hash and never changes its default_proc,
so only pay the hash lookup cost once; we know missing entries
in the hash will be nil.

* lib/resolv.rb (each_name): use safe navigation operator

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@56890 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

Use `&.` instead of modifier if

resolv: use symbol proc when possible

2016-11-21T23:50:31+00:00

This reduces both human code and bytecode.

lib/resolv.rb (sender_for, Config.parse_resolv_conf): use symbol proc
