Deprecation: Launchd hash Property (CHEF-12)
The launchd resource has a property called hash which conflicts with
the already-existing Ruby hash method that exists on every object.
The CHEF-11 deprecation
warns whenever a resource property is named the same as an existing Ruby
method. Chef’s core launchd resource is guilty of this behavior. The
hash property accepts a Ruby Hash containing the data to be output to
the launchd property list. However, hash is an already-existing Ruby
method.
A deprecation warning is logged when the hash property is used. In
Chef Client 13, this will raise an exception and your Chef run will
fail.
The Cookstyle cop ChefDeprecations/LaunchdDeprecatedHashProperty has been introduced to detect and autocorrect this deprecation.
Remediation
When using the launchd resource and passing a hash for the launchd
property list, use the plist_hash property instead of the hash
property.
