[chef] Re: Overriding attributes

[DV < >]

Ran into this issue today so thought I'd revive this thread.

I'm using postgresql cookbook with chef-solo and cookbook attributes
aren't merged together with attributes set in .json file passed to
chef-solo. Instead .json file attributes override those set in
cookbook.

Here's what's in postgresql/attributes/default.rb:
...
default['postgresql']['pg_hba'] = [
  {:type => 'local', :db => 'all', :user => 'postgres', :addr => nil,
:method => 'ident'},
  {:type => 'local', :db => 'all', :user => 'all', :addr => nil,
:method => 'ident'},
  {:type => 'host', :db => 'all', :user => 'all', :addr =>
'127.0.0.1/32', :method => 'md5'},
  {:type => 'host', :db => 'all', :user => 'all', :addr => '::1/128',
:method => 'md5'}
]
...

Here's what in my .json file:
...
{
...
  "postgresql": {
...
    "pg_hba": [
      { "type": "host", "db": "replication", "user": "postgres",
"addr": "10.0.0.0/8", "method": "trust" }
    ],
...
  "run_list": [ "recipe[postgresql::server]" ]
}

Resulting pg_hba.conf has only one line in it:

host    replication     postgres        10.0.0.0/8              trust

Since node[:postgresq][:pg_hba] is an array attribute, it should be
merged rather than overwritten.

The behavior is same with chef-solo 10.28.0 and 11.6.0.

I'll go ahead and submit that as a defect unless someone thinks it's
intended behavior.
