[1.9] YAML anchors & alias merging regression
---------------------------------------------
Key: JRUBY-5396
URL: http://jira.codehaus.org/browse/JRUBY-5396
Project: JRuby
Issue Type: Bug
Components: Ruby 1.9
Environment: jruby 1.6.0.RC1 (ruby 1.9.2 patchlevel 136) (2011-01-20
36b741d) (Java HotSpot(TM) 64-Bit Server VM 1.6.0_22) [darwin-x86_64-java]
Reporter: Matt Fletcher
Assignee: Thomas E Enebo
Attachments: test_yaml_merging.rb
Important note: this bug is showing up in the latest HEAD, but does not happen
in 1.6.0 RC1.
Attached is a test case where two hashes are defined: defaults and production.
The production hash attempts to merge in the contents of the defaults hash
using the <<: syntax. After the merge, the production hash only has the
contents of the defaults hash--the other stuff in production is lost.
This test passes in MRI 1.9.2, JRuby 1.6.0 RC1, and JRuby HEAD --1.8. It fails
under JRuby HEAD --1.9.
