Bug #2021: Returning boolean not always possible
/issues/2021
Author: immerda
Status: Unreviewed
Priority: Normal
Assigned to:
Category: binary
Target version: 1.5.4
Complexity: Unknown
Keywords: boolean, return
assume the following code:
<pre>
#cat facter/selinux.rb
Facter.add("selinux") do
confine :kernel => :linux
setcode do
result = false
if FileTest.exists?("/selinux/enforce")
result = true
end
result
end
end
</pre>
one time it is working, the other time not:
<pre>
# export RUBYLIB=`pwd`
# facter selinux
false
# facter
/usr/lib/ruby/site_ruby/1.8/facter/util/confine.rb:37:in `true?': undefined
method `downcase' for false:FalseClass (NoMethodError)
from /usr/lib/ruby/site_ruby/1.8/facter/util/confine.rb:36:in `each'
from /usr/lib/ruby/site_ruby/1.8/facter/util/confine.rb:36:in `true?'
from /usr/lib/ruby/site_ruby/1.8/facter/util/resolution.rb:101:in
`suitable?'
from /usr/lib/ruby/site_ruby/1.8/facter/util/ip.rb:145:in `detect'
from /usr/lib/ruby/site_ruby/1.8/facter/util/resolution.rb:101:in `each'
from /usr/lib/ruby/site_ruby/1.8/facter/util/resolution.rb:101:in
`detect'
from /usr/lib/ruby/site_ruby/1.8/facter/util/resolution.rb:101:in
`suitable?'
from /usr/lib/ruby/site_ruby/1.8/facter/util/fact.rb:72:in `value'
... 10 levels...
from /usr/lib/ruby/site_ruby/1.8/facter/util/collection.rb:103:in
`to_hash'
from /usr/lib/ruby/site_ruby/1.8/facter.rb:92:in `send'
from /usr/lib/ruby/site_ruby/1.8/facter.rb:92:in `to_hash'
from /usr/bin/facter:125
</pre>
if I debug it I can see that value/values is one time a string and the other
time a FalseClass or TrueClass
Please note that returning a string isn't possible due to a bug in puppet I'll
report shortly.
This worked on 1.3.8.
