[Puppet Users] Re: Issue with puppet file serving api not parsing yaml content correctly
Unfortunately, it does not work. That was the first thing I had tried
to try and reproduce the problem in ruby outside a puppet run.
Also, here are the ruby util modules for puppet in 0.25.4:
/opt/ruby-1.8.6-p287/lib/ruby/site_ruby/1.8/puppet/util
autoload
autoload.rb
backups.rb
cacher.rb
checksums.rb
classgen.rb
config_store.rb
constant_inflector.rb
diff.rb
docs.rb
errors.rb
execution.rb
feature.rb
file_locking.rb
fileparsing.rb
filetype.rb
graph.rb
inifile.rb
instance_loader.rb
ldap
ldap.rb
loadedfile.rb
logging.rb
log_paths.rb
log.rb
metaid.rb
methodhelper.rb
metric.rb
monkey_patches.rb
nagios_maker.rb
package.rb
pidlock.rb
posix.rb
provider_features.rb
pson.rb
queue
queue.rb
rails
rdoc
rdoc.rb
reference.rb
resource_template.rb
selinux.rb
settings
settings.rb
storage.rb
subclass_loader.rb
suidmanager.rb
tagging.rb
user_attr.rb
warnings.rb
Also, I did not see anything in the monkey_patches.rb file pertaining
to a yaml like patch only rdoc.:
module RDoc
def self.caller(skip=nil)
in_gem_wrapper = false
Kernel.caller.reject { |call|
in_gem_wrapper ||= call =~ /#{Regexp.escape $0}:\d+:in
`load'/
}
end
end
I think at this point we will probably upgrade puppet anyways so I
will just add "require puppet/util/yaml" once we have upgraded.

[Puppet Users] Re: Issue with puppet file serving api not parsing yaml content correctly
Thanks. Unfortunately, it seems I will need to wait until we upgrade
puppet as version 0.25.4 does not seem to have 'puppet/util/zaml'.
