Affected Puppet version: 2.7.6
Keywords:
Branch:
On a fresh install of Puppet Enterprise 2.0 on CentOS 5.5 x86_64:
<pre>
[root@localhost ~]# puppet ca list --trace --debug --verbose
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/face/ca.rb:78:in
`list_when_rendering_console'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/application/face_base.rb:43:in `call'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/application/face_base.rb:43:in
`render'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/application/face_base.rb:236:in `main'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/application.rb:314:in `run_command'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/application.rb:306:in `run'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/application.rb:410:in `hook'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/application.rb:306:in `run'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/application.rb:401:in `exit_on_fail'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/application.rb:306:in `run'
/opt/puppet/lib/ruby/site_ruby/1.8/puppet/util/command_line.rb:69:in `execute'
/usr/local/bin/puppet:4
err: undefined method `+' for nil:NilClass
err: Try 'puppet help ca list' for usage
</pre>
The errant line appears to be:
<pre>
length = hosts.map{|x| x.name.length }.max + 1
</pre>
[].max is nil, so this line needs some safeguards in place when there are no
hosts found to display.
