Reopening a file descriptor on a socket doesn't work (gives "could not reopen:
null (IOError)")
-----------------------------------------------------------------------------------------------
Key: JRUBY-5222
URL: http://jira.codehaus.org/browse/JRUBY-5222
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.5.5, JRuby 1.1.6
Environment: Tested under Ubuntu 10.04, OpenJDK 1.6.0_18
Reporter: Matthew Bloch
Priority: Minor
STDIN.reopen doesn't work for me if I specify an open TCP socket, as it does in
MRI. Here's a test:
{code:title=reopen|borderStyle=solid}
p RUBY_VERSION
begin
p JRUBY_VERSION
p Java::java::lang::System.getProperty("java.vendor")
p Java::java::lang::System.getProperty("java.version")
rescue NameError => name
end
require 'socket'
server = TCPServer.new("127.0.0.1",11112)
another_thread = Thread.new { TCPSocket.new("127.0.0.1",11112).write("x"*99) }
client = server.accept
STDIN.reopen(client)
p STDIN.read(99)
{code}
And here's me running it under a couple of different Javas, and JRuby 1.5.5.
The same thing happened under the ancient system JRuby (1.1.6):
