Derived Attributes Non-Functional in Chef 12+

[joshburt]

Validated that the 11.x Chef clients work fine, and the issue is present only in 12+ environments.

Within the cookbook attribute file: iis/attributes/default.rb

This is currently defined:
default['iis']['home'] = "#{ENV['WINDIR']}\\System32\\inetsrv"
default['iis']['conf_dir'] = "#{iis['home']}\\config"
default['iis']['pubroot'] = "#{ENV['SYSTEMDRIVE']}\\inetpub"
default['iis']['docroot'] = "#{iis['pubroot']}\\wwwroot"
default['iis']['log_dir'] = "#{iis['pubroot']}\\logs\\LogFiles"
default['iis']['cache_dir'] = "#{iis['pubroot']}\\temp"

As of chef 12 only the first derived attribute is properly calculated. Printing out the values within a run is enough to see the issue:
DEBUG: default['iis']['home'] = C:\Windows\System32\inetsrv
DEBUG: default['iis']['conf_dir'] = C:\Windows\System32\inetsrv\config
DEBUG: default['iis']['pubroot'] = C:\inetpub
DEBUG: default['iis']['docroot'] = \wwwroot
DEBUG: default['iis']['log_dir'] = \logs\LogFiles
DEBUG: default['iis']['cache_dir'] = \temp

You can see that only the first attribute is properly calculated be reversing the order of declaration and running again:
default['iis']['pubroot'] = "#{ENV['SYSTEMDRIVE']}\\inetpub"
default['iis']['docroot'] = "#{iis['pubroot']}\\wwwroot"
default['iis']['log_dir'] = "#{iis['pubroot']}\\logs\\LogFiles"
default['iis']['cache_dir'] = "#{iis['pubroot']}\\temp"
default['iis']['home'] = "#{ENV['WINDIR']}\\System32\\inetsrv"
default['iis']['conf_dir'] = "#{iis['home']}\\config"

In this scenario only iis[home] will be empty.

If you fully declare the attributes as below it works in other recipes:
default['iis']['home'] = "#{ENV['WINDIR']}\\System32\\inetsrv"
default['iis']['conf_dir'] = "#{ENV['WINDIR']}\\System32\\inetsrv\\config"
default['iis']['pubroot'] = "#{ENV['SYSTEMDRIVE']}\\inetpub"
default['iis']['docroot'] = "#{ENV['SYSTEMDRIVE']}\\inetpub\\wwwroot"
default['iis']['log_dir'] = "#{ENV['SYSTEMDRIVE']}\\inetpub\\logs\\LogFiles"
default['iis']['cache_dir'] = "#{ENV['SYSTEMDRIVE']}\\inetpub\\temp

@joshburt thanks for bringing this to my attention, i've added a pull request...

@smurawski I have to believe this is a real issue as without test-kitchen I do not test chef 12+. I'll be at chef con attending the test-kitchen training so hopefully we can get this repo better tested.

[joshburt]

Thanks for the quick response! We're re-factoring code to support a Chef 12 upgrade, and this was definitely something we needed help with.

@joshburt never a problem, as we are working to make iis@3 a release bugs need to be resolved.

I don't actually see any of those attributes, save for iis home being referenced anywhere else in this cookbook. Do we need these attributes at all? @joshburt - how are you using these attributes? Do you need them in this cookbook or can you just generate them yourself within your recipes?

[EasyAsABC123]

@ksubrama you are correct only ['iis']['home'] is in use, however a lot of the other attributes should likely be used as the default logging path and cache path.
