I inherited a cookbook utilizing another cookbook with a custom resource.

I'm trying to figure out the use of the new_resource in this code.

In the code below, path new_resource.fullpath causes a "non-defined method."

When I changed that line to simply path fullpath to reference the local variable, it worked just fine. I can't figure out what the previous intent was.

I'm sure this is an easy one. Looking for an ELI5. Thanks!

Full code Block.

resource_name :mb_worker_role
default_action :create

property :service_name, String, name_property: true
property :root_path, String, required: true
property :executable, String, required: true
property :wcf_port, [Integer, String], default: 808
property :health_port, [Integer, String], default: 8000
property :use_dummy, [TrueClass, FalseClass], default: true

action :create do
 # Create firewall allow for WCF port
 windows_firewall_rule "#new_resource.service_name - WCF" do
 localport new_resource.wcf_port.to_s
 protocol 'TCP'
 firewall_action :allow
 end

 # Create firewall allow for health port
 windows_firewall_rule "#new_resource.service_name - Health" do
 localport new_resource.health_port.to_s
 protocol 'TCP'
 firewall_action :allow
 end

 # Full path to service executable at root_pathexecutable
 fullpath = "#new_resource.root_path\#new_resource.executable"

 # Create directory for worker role application root
 directory new_resource.root_path do
 recursive true
 action :create
 end

 # Set NetTCPPortSharing to start on demand
 windows_service 'NetTCPPortSharing' do
 action :configure_startup
 startup_type :manual
 end

 # Stage the dummy worker role executable if requested
 # Only used to verify this resource when testing
 if property_is_set?(:use_dummy)
 cookbook_file 'Stage dummy worker role executable' do
 # path new_resource.fullpath
 path fullpath
 cookbook 'mb_worker_role'
 source 'WorkerRole.Default.exe'
 only_if new_resource.use_dummy 
 action :create
 end
 end

 # Create windows service if it does not exist
 powershell_script "Installing Windows service #new_resource.service_name" do
 code <<-EOH
 # Create the Windows service
 sc.exe create "#new_resource.service_name" binPath="#fullpath"
 EOH
 not_if "(Get-Service -Name #new_resource.service_name).Name -eq '#new_resource.service_name'"
 end

 # Set service to automatic and make sure it's running
 windows_service new_resource.service_name do
 action [:configure_startup, :enable, :start]
 startup_type :automatic
 end
end

path fullpath is a magical alias system that we actively discourage at this point. It was a nice thing to try, but the syntax has a lot of problems that result in unexpected behavior. Use new_resource.fullpath, far fewer footguns.
