Vinutha Nayak created JRUBY-6301:
------------------------------------
Summary: scripting_lang.jruby:undefined method in test_loop_1_9.rb
Key: JRUBY-6301
URL: https://jira.codehaus.org/browse/JRUBY-6301
Project: JRuby
Issue Type: Bug
Components: Launcher
Affects Versions: JRuby 1.7
Reporter: Vinutha Nayak
Assignee: Thomas E Enebo
Fix For: JRuby 1.7
Again this testcase seems to be part of the one that is shipped with ruby 1.7.0
source .
require 'test/unit'
class TestLoop19 < Test::Unit::TestCase
def test_loop_catches_rescues_iteration_and_does_not_export_scope
loop do
n = 1
raise StopIteration
end
assert_raises NameError do n end <--------------------------------
end
end
While running this against Java 7 SR1 , I get the following error
test_loop_catches_rescues_iteration_and_does_not_export_scope(TestLoop19):
NoMethodError: undefined method `foo' for #<TestLoop19:0xcf5a8ceb>
<--------------------------------------------------
/home/vinunaya/ruby/test/test_loop_1_9.rb:6:in
`test_loop_catches_rescues_iteration_and_does_not_export_scope'
org/jruby/RubyKernel.java:1342:in `loop'
/home/vinunaya/ruby/test/test_loop_1_9.rb:5:in
`test_loop_catches_rescues_iteration_and_does_not_export_scope'
org/jruby/RubyKernel.java:1944:in `send'
org/jruby/RubyArray.java:1603:in `each'
org/jruby/RubyArray.java:1603:in `each'
So if we observed the lines pointed out in the above failure message , it is
basically getting a "NoMethodError" from the "do...end" block rather than the
"NameError" expected.
So further looking into the issue , the above can be recreated even with a
simple change to testcase .
class TestLoop19 < Test::Unit::TestCase
def test_loop_catches_rescues_iteration_and_does_not_export_scope
loop do
puts foo <--------------------------
raise StopIteration
end
end
So here I have removed the assertion and added a "puts " statement instead. If
I run this with Java 7 SR1 , I get the error as mentioned above where as with
Java 6 I get "NameError" as expected .
As per http://www.ruby-doc.org/core-1.9.3/NameError.html documentation we
should be getting the "NameError" error itself .
Again here also ,when I tried running jruby with "--debug" option ( on Java7
SR1 line) I see the testcase passes .
I have raised JRUBY-6300 which was for slightly different issue but there too
with "--debug" option it was passing . So I am not sure if these are related .
If yes can you please let me know the build number where this is fixed . If not
, can you please help with this issue . ?
