Bug #14378: Expressions in Augeas context cause optimisation matching error
https://projects.puppetlabs.com/issues/14378#change-65401

Author: Dominic Cleal
Status: In Topic Branch Pending Review
Priority: Normal
Assignee: Dominic Cleal
Category: augeas
Target version: 3.0.0
Affected Puppet version: 3.0.0rc3
Keywords: augeas error
Branch: https://github.com/puppetlabs/puppet/pull/835


When an augeas resource has a context given that contains a complex path 
expression, this causes the optimisation added in #7285 to break as it doesn't 
escape quotes.

An example that I hit it on:

    augeas { 'sudowheel':
      context => "/files/etc/sudoers/spec[user = '%wheel' and host_group/host = 
'ALL']",
      changes => [
        "set user %wheel",
        "set host_group/host ALL",
        "set host_group/command ALL",
        "set host_group/command/runas_user root",
      ],
    }

Generates:
    err: /Stage[main]//Augeas[sudowheel]: Could not evaluate: unknown error - 
Matching path expression '/augeas/load/*['/etc/sudoers/spec[user = '%wheel' and 
host_group/host = 'ALL']/' !~ glob(incl) + regexp('/.*')]' failed

Either the optimisation should be disabled with anything reasonably complex 
(probably best), or it'd have to escape any problematic characters (would need 
to check the pathx parser to see what it understands).
