----------------------------------------
Bug #20901: puppet --version is unnecessarily slow
https://projects.puppetlabs.com/issues/20901#change-94904

* Author: Josh Cooper
* Status: Closed
* Priority: Normal
* Assignee: 
* Category: 
* Target version: 3.2.3
* Affected Puppet version: 3.2.1
* Keywords: webrick
* Branch: https://github.com/puppetlabs/puppet/pull/1667
----------------------------------------
As of 2.7.0, puppet agents POST fact data avoiding the maximum GET URI length 
imposed by most proxy & webservers, see #6117. In 3.2.1, a patch was added to 
increasee webrick's MAX_URI_LENGTH enabling puppet masters to accept facts from 
older agents, see #18781. However, the patch requires 'webrick' during puppet 
startup (as opposed to when starting webrick). And webrick performs a reverse 
DNS lookup of the local IP, which may take awhile depending on your DNS 
configuration. As a result, some users have seen `puppet --version` take 
upwards of 10 seconds.

One fix would be to move webrick monkey patching to the puppet's 
`lib/network/http/webrick` code. However, Puppet 3 does not support 2.6 agents, 
so we can drop this patch entirely.

Note this issue is similar to issue #20194, except that issue was about 
puppet's webrick performing reverse DNS lookups of each connected client, and 
this is about webrick performing a reverse lookup of its local IP address.
