Bug #19306: Puppet option parser accepts partial matches but doesn't use them
to alter configuration values
https://projects.puppetlabs.com/issues/19306
Author: Charlie Sharpsteen
Status: Unreviewed
Priority: Normal

Target version:
Affected Puppet version: 3.1.0
Keywords: options
Branch:
This popped up during investigation of #19153.
When a Puppet command such as `agent` encounters an unknown option, it throws a
warning:
# puppet agent --foo
Error: Could not parse application options: invalid option: --foo
Similarly, when it encounters a known option, it will alter a config value:
# puppet agent --configprint daemonize
true
# puppet agent --no-daemonize --configprint daemonize
false
However, the parser will also accept partial matches:
# puppet agent --no-daemoniz --configprint daemonize
true
# puppet agent --no-daemon --configprint daemonize
true
# puppet agent --no-da --configprint daemonize
true
Edge Cases:
# puppet agent --no-daemonizer --configprint daemonize
Error: Could not parse application options: invalid option: --no-daemonizer
# puppet agent --no-d --configprint daemonize
Error: Could not parse application options: ambiguous option: --no-d
The problems with partial matching is that the flags don't alter configuration
values and no warning or error is emitted to alert users that their input is
incorrect or that their intentions are not being honored.
