Subject: [ruby-core:117027] [Ruby master Bug#20319] Singleton class is being frozen lazily in some cases
Date: Fri, 01 Mar 2024 11:52:13 +0000 (UTC) [thread overview]
Message-ID: <redmine.issue-20319.20240301115212.13553@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-20319.20240301115212.13553@ruby-lang.org
Issue #20319 has been reported by andrykonchin (Andrew Konchin).
----------------------------------------
Bug #20319: Singleton class is being frozen lazily in some cases
https://bugs.ruby-lang.org/issues/20319
* Author: andrykonchin (Andrew Konchin)
* Status: Open
* ruby -v: 3.2.2
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
I've noticed suspicious behaviour (it doesn't affect anything in practice for me though) when an object becomes frozen only its own singleton class becomes frozen immediately.
A singleton class of the immediate singleton class becomes frozen lazily after `#singleton_class` method call:
```ruby
o = Object.new
klass = o.singleton_class.singleton_class
o.freeze
puts klass.frozen? # false <== here we expect true
puts o.singleton_class.singleton_class.frozen? # true
puts klass.frozen? # true
```
I would expect all created singleton classes in an object singleton classes chain to become frozen immediately.
