Backport #5415: YAML serialization problem for Exception

• Status: Closed
• Assignee: -

[jingweno (Owen Ou)]

The implementation of YAML.object_maker allocates an object and
instance_variable_set the instance variables passed as the second
argument, while Exception doesn't seem to use such instance variable to
return the exception message (Exception#message). This bug can be
reproduced by typing
YAML::load(YAML::dump(Exception.new('test_message'))) in IRB.

this bug can be reproduced in Ruby 1.8 as well

[jingweno (Owen Ou)]

To reproduce the bug, try this on IRB:

ruby-1.9.2-p290 :001 > require 'yaml'
=> true
ruby-1.9.2-p290 :002 > YAML::load(YAML::dump(Exception.new('test_message')))
=> #<Exception: Exception>

I expect to see #<Exception: "test_message"> while the result is #<Exception: Exception>.

I have fixed this problem with a pull request on August 09 2011 which hasn't been merged in till now: https://github.com/ruby/ruby/pull/41
