IO#reopen should be able to handle argument of arbitrary type if it responds to
"to_io"
----------------------------------------------------------------------------------------
Key: JRUBY-1909
URL: http://jira.codehaus.org/browse/JRUBY-1909
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1b2
Environment: Latest JRuby 1.1b1
Reporter: Vladimir Sizikov
Consider the following example:
{noformat}
obj = Object.new
def obj.to_io
File.open("/tmp/some-file", "w+")
end
p "Before reopen"
$stdout.reopen(obj)
p "After reopen"
{noformat}
MRI prints:
"Before reopen"
JRuby prints:
"Before reopen"
"After reopen"
MRI correctly forwards "After repopen" message to the object, specified in
to_io. In our case - to a file.
JRuby doesn't understand argument of non-IO type, doesn't call the to_io
method, and just
silently ignores the whole reopen thing in this case, not changing anything.
Fix is coming.
