Subject: [ruby-core:79124] [Ruby trunk Bug#13115][Assigned] `YAML.dump` outputs deperecated message even with delegated object
Date: Wed, 18 Jan 2017 12:30:16 +0000 [thread overview]
Message-ID: <redmine.journal-62536.20170118123015.1c283912c690baf2@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-13115.20170108115036@ruby-lang.org
Issue #13115 has been updated by Nobuyoshi Nakada.
Status changed from Open to Assigned
Assignee set to Aaron Patterson
Psych warns if `to_yaml` method is defined by other than psych itself, and delegated methods are defined in `delegate.rb`.
You can avoid the warning by `undef to_yaml` in `class Delegated`.
----------------------------------------
Bug #13115: `YAML.dump` outputs deperecated message even with delegated object
https://bugs.ruby-lang.org/issues/13115#change-62536
* Author: Fumiaki Matsushima
* Status: Assigned
* Priority: Normal
* Assignee: Aaron Patterson
* Target version:
* ruby -v: ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
`YAML.dump` outputs deprecated message if it calls with delegated object
but doesn't with inherited object:
~~~ ruby
require 'yaml'
require 'delegate'
$VERBOSE = true
class Delegated < DelegateClass(Object)
def initialize
super(Object.new)
end
end
puts 'YAML.dump(Delegated.new)'
YAML.dump(Delegated.new)
class Inherited < Object
end
puts 'YAML.dump(Inherited.new)'
YAML.dump(Inherited.new)
# $ ruby test.rb
# YAML.dump(Delegated.new)
# implementing to_yaml is deprecated, please implement "encode_with"
# YAML.dump(Inherited.new)
~~~
Is this intentional?
