$defout and $deferr are not changed when $stdout and $stderr modified
---------------------------------------------------------------------
Key: JRUBY-1849
URL: http://jira.codehaus.org/browse/JRUBY-1849
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.x
Environment: Latest JRuby 1.1b1
Reporter: Vladimir Sizikov
Attachments: defout-deferr-values.patch
Consider the following example, where $stdout and $stderr are redefined, but
$defout and $deferr are not.
{noformat}
class CaptureOutput < String
def write(*str)
self << str.to_s
end
end
$stdout = CaptureOutput.new
$stderr = CaptureOutput.new
$defout.puts "DEFOUT\n"
$deferr.write "DEFERR\n"
{noformat}
MRI 1.8.6, MRI 1.9 print nothing.
JRuby prints:
DEFOUT
DEFERR
This leads to additional noise when running rubinius specs for getoptlong:
{noformat}
#>bin/mspec -V -t j ruby/spec/1.8/library/getoptlong/
Started
ruby/spec/1.8/library/getoptlong//each_option_spec.rb.

ruby/spec/1.8/library/getoptlong//ordering_spec.rbtmp/last_mspec.rb: argument

{noformat}
The proposed patch fixes the problem and eliminates the extra noise when
running the specs.
