BSF does not retain local scope between eval calls
--------------------------------------------------
Key: JRUBY-3215
URL: http://jira.codehaus.org/browse/JRUBY-3215
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.1.5, JRuby 1.1.6
Environment: Windows Vista and OS X 10.5.5 with JRuby 1.1.5 / 1.1.6RC1
Reporter: Adam Murray
Priority: Minor
Fix For: JRuby 1.1.6
Attachments: LocalVariableTest.java
I expect that when using BSF, the local scope will persist between eval calls
until I call the bsfManager.terminate() method. The use case for this is an
irb-like interface implemented in Java.
A test case LocalVariableTest is attached that demonstrates this issue. Up
until JRuby 1.1.5, this worked, but starting with version JRuby 1.1.5 and in
1.1.6RC1 it has the following behavior:
1.1.6RC1
Failed to evaluate: puts x
Exception: (java):2: undefined local variable or method `x' for main:Object
(NameError)
...internal jruby stack elided...
from (unknown).(unknown)(:1)
A patch for this issue was provided for 1.1.5 by Yoko Harada in this mailing
list thread:
http://www.ruby-forum.com/topic/170058
Using that solution, I thought this issue could be resolved for 1.1.6RC1 by
changing org.jruby.Ruby.jave line 223 from
Node node = parseEval(script, "<script>", newScope, 0);
to
Node node = parseEval(script, "<script>", newScope.getNextCapturedScope(), 0);
However, I tried this and it does not seem to work.
Can this be fixed for 1.1.6? If not, what are my options for supporting this
use case? Should I be using JavaEmbedUtils?
