StringIO#rewind doesn't clear EOF flag, fails new rubyspec
----------------------------------------------------------
Key: JRUBY-2362
URL: http://jira.codehaus.org/browse/JRUBY-2362
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.1
Environment: Latest JRuby 1.1
Reporter: Vladimir Sizikov
Assignee: Vladimir Sizikov
Fix For: JRuby 1.1.1
The following example:
{noformat}
require 'stringio'
@io = StringIO.new("hello\nworld")
str = @io.string
p @io.read(@io.string.length + 1)
@io.rewind
p @io.read(@io.string.length + 1)
{noformat}
Returns on MRI:
"hello\nworld"
"hello\nworld"
But on JRuby:
"hello\nworld"
nil
It causes one rubyspec failure too:
{noformat}
#>bin/mspec ci -t j -X /opt/work/jruby.git/test/spec_excludes
spec/ruby/1.8/library/stringio/rewind_spec.rb
..F
1)
StringIO#rewind should make the contents of the stream accessible again when
stream was read beyond its end FAILED
Expected nil
to equal "hello\nworld"
