MatchData#select bug
--------------------
Key: JRUBY-3045
URL: http://jira.codehaus.org/browse/JRUBY-3045
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Environment: OS X, jruby 1.1.4 (ruby 1.8.6 patchlevel 114) (2008-10-04
rev 7830) [i386-java]
Reporter: Daniel Berger
Fix For: JRuby 1.1.5
Looks like MatchData#select is busted. Below are the tests I'm using:
{noformat}
class TC_MatchData_Select_InstanceMethod < Test::Unit::TestCase
def setup
@string = 'THX1138'
@regex = /(.)(.)(\d+)(\d)/
@nested = /(\d(\w(\w)\w)\d)/
@plain = /\w+/
@match = @regex.match(@string)
end
def test_select_basic
assert_respond_to(@match, :select)
assert_nothing_raised{ @match.select{} }
assert_kind_of(Array, @match.select{})
end
def test_select
assert_equal(['HX1138', '113', '8'], @match.select{ |x| x =~ /\d/ })
assert_equal(['1abc2', '1abc2'], @nested.match('1abc2').select{ |x| x =~
/\d/ })
assert_equal([], @plain.match('hello').select{ |x| x =~ /\d/ })
end
def test_select_expected_errors
assert_raise(ArgumentError){ @match.select(1) }
assert_raise(LocalJumpError){ @match.select }
end
def teardown
@string = nil
@regex = nil
@nested = nil
@plain = nil
@match = nil
end
end
{noformat}
Here are the failures with JRuby:
{noformat}
4) Failure:
