Inconsistent DynamicScope instances in evalScriptlet
----------------------------------------------------
Key: JRUBY-3127
URL: http://jira.codehaus.org/browse/JRUBY-3127
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1.5
Reporter: Yoko Harada
Attachments: Ruby.patch
Since JRuby 1.1.5, ManyVarsDynamicScope has been introduced in evalScriptlet
and is used to parse scripts. However, implementations of a Node.interpret
method remain unchanged and use different instance of DynamicScope from the one
used for parsing. This causes the trouble posted in jruby-users ml,
http://www.nabble.com/JRuby-1.1.5-%2B-BSF%3A-local-variables-no-longer-persist-between-calls-to-eval%28%29-td20337547.html.
To resolve this issue completely, Node.interpret probably should have some way
of receiving DynamicScope type instance so that the same DynamicScope instance
will be used in both parsing and interpreting.
Attached patch is the fix to make parser use the same DynamicScope instance as
interpreter.
