Subject: [ruby-core:105504] [Ruby master Bug#18232] Ractor.make_shareable is broken in code loaded with RubyVM::InstructionSequence.load_from_binary
Date: Thu, 30 Sep 2021 11:47:45 +0000 (UTC) [thread overview]
Message-ID: <redmine.issue-18232.20210930114744.7941@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-18232.20210930114744.7941@ruby-lang.org
Issue #18232 has been reported by byroot (Jean Boussier).
----------------------------------------
Bug #18232: Ractor.make_shareable is broken in code loaded with RubyVM::InstructionSequence.load_from_binary
https://bugs.ruby-lang.org/issues/18232
* Author: byroot (Jean Boussier)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.0.2p107, ruby 3.1.0dev
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
This was first reported as a Bootsnap bug: https://github.com/Shopify/bootsnap/issues/376
But I reduced it to:
```ruby
source = <<~RUBY
x = :foo
pr = Proc.new { p x }
Ractor.make_shareable(pr)
pr.call
RUBY
RubyVM::InstructionSequence.compile(source).eval # :foo
RubyVM::InstructionSequence.load_from_binary(RubyVM::InstructionSequence.compile(source).to_binary).eval # false
```
The bug is present on both 3.0.2 and 3.1.0-dev. I have no idea what might cause this.
