[chef] Re: Array attributes merge

[Michael Glenney < >]

I don't have a complete answer but I know that:

1)  The doc you linked to specifically calls out roles and environments. Might be a clue

2)  When writing a provider for a cookbook attributes are mutable. So maybe this will work for you within a recipe: 

node.default['foo'] << 'bar'

Hi guys!

According to this: http://docs.opscode.com/essentials_node_object_deep_merge.html#addition

Array attributes are merged, i have checked out that this is the behaviour when using default attributes on attribute files and roles.

But when i try to define a default attribute on one recipe:

node.default['foo'] = ['bar']

The one that i have already on defaults.rb attribute file:

node.default['foo'] = ['littlebar']

Is overrided by the one i defined on the recipe, resulting node['foo'] = ['bar']

Defining on  a role:

default_attributes (:foo => ['bar'])

Works as expected, and results on node['foo']  = ['littlebar','bar']

So what exactly node.default['x'] = value do on recipes? Looks like a direct override... O_o
