Not able to set registry_key value being passed from ruby_block

sjethvani · July 12, 2021, 2:10pm

I have recipe , where I am basically trying to update multi_string windows registry using registry_key chef resource . I have to make some conditional checks on existing value before updating it & hence I am using ruby_block for doing so.
However I am facing an issue where in node attributes are not getting evaluated lazily , I am using this lazy node attr for setting registry value.

For more detailed info , I am pasting a full recipe code here for analysis

# Cookbook:: myCookbook
# Recipe:: myrecipe-rectify-java-param-tomcat-service
# In brief , this recipe does simple things 
### 1 Fetch existing value of registry(HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\ABC\Parameters\Java)
### 2 Check if it has '-Dsun.net.maxDatagramSockets' in it , if yes then update its value , if no then add -Dsun.net.maxDatagramSockets=1024 entry in it
### 3 Update registry(HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\ABC\Parameters\Java)


node.default['myCookbook']['options_value'] = nil
node.default['myCookbook']['existing_java_key_value'] = nil

#1 
ruby_block "fetching JAVA options of ABC tomcat service" do
  block do
    node.override['myCookbook']['existing_java_key_value'] = registry_get_values('HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\ABC\Parameters\Java', :x86_64)
    node['myCookbook']['existing_java_key_value'].each{|e| 
      if e[:name] == "Options"
          node.override['myCookbook']['options_value'] = e[:data]
          Chef::Log.info("1--- herrreeee options value is ")
          Chef::Log.info(node['myCookbook']['options_value'])
      end
    }
  end
  action :run
end

#2
ruby_block "modifying JAVA reg key value through ruby block" do
  block do
    Chef::Log.info("2--- here in ruby lblockck ")
    Chef::Log.info("2.1 --- options_value is ")
  
    doesItemExist = false
      indexis = 0
    node['myCookbook']['options_value'].each_with_index { |item,index| 
      if (item.include? "-Dsun.net.maxDatagramSockets")
        Chef::Log.info("item is "+item)
        doesItemExist = true
            indexis = index
        break
      end
    }
    if (doesItemExist)
      Chef::Log.info("hey registry already has maxDatagramSockets thing at index #{indexis} , so need to replace it")
        node.override['myCookbook']['options_value'][indexis]="-Dsun.net.maxDatagramSockets=#{node['myCookbook']['abcservice']['max_datagram_socket']}"
    else
      Chef::Log.info("Seems it is first time we are adding maxDatagramsocket")
      node.override['myCookbook']['options_value'].insert(-1, "-Dsun.net.maxDatagramSockets=#{node['myCookbook']['abcservice']['max_datagram_socket']}")
    end
    Chef::Log.info("2.2 ##### #{node['myCookbook']['options_value']} #####")
    Chef::Log.info(node['myCookbook']['options_value'])
  end
  action :run
end

#3
registry_key 'HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\ABC\Parameters\Java' do
  values [{
    name: 'Options',
    type: :multi_string,
    #data: options_value
    data: lazy { node[myCookbook][:options_value] }
  }]
  action :create
end

Error , which I receive when running this recipe through chef solo , I face an issue at Step#3 (i.e setting registry with updated value) , it seems that lazy node attribute node[myCookbook][:options_value] is still having nil value & doesn't persist the value , which I am setting in ruby_block

Can some one please reply on this .

I know that undefined method 'to_a' is because node[myCookbook][:options_value] is not having any value at convergence (2nd phase) phase of execution . However I still don't understand why that is the case , since I am using 'lazy' evaluation . That's what lazy is used for . Right ?
