[jruby-dev] [jira] (JRUBY-6966) Open3.popen3 does not take optional environment hash as first argument

Thu, 25 Oct 2012 14:40:20 -0700

Issue Type: Bug Bug
Affects Versions: JRuby 1.7.0
Assignee: Thomas E Enebo
Components: Standard Library
Created: 25/Oct/12 4:39 PM
Description:

Here I try to use Open3.popen3() to execute a bash script which prints out the environment variable FOO.

Here are the contents of the bash script /tmp/tst.sh :

#!/bin/bash

echo $FOO



Here I am able to successfully execute it using MRI ruby 1.9.3-p194 :




1.9.3p194 :001 > require 'open3'
 => true 
1.9.3p194 :002 > r = nil; Open3.popen3({'FOO' => 'bar'}, '/tmp/tst.sh') { |sin, sout, serr, wthr| r = sout.gets }
 => "bar\n" 
1.9.3p194 :003 > 






Here it fails using jruby 1.7.0 :




jruby-1.7.0 :001 > require 'open3'
 => true 
jruby-1.7.0 :002 > r = nil; Open3.popen3({'FOO' => 'bar'}, '/tmp/tst.sh') { |sin, sout, serr, wthr| r = sout.gets }
IOError: Cannot run program "{"FOO"=>"bar"}" (in directory "/Users/tim/git/1/jux"): error=2, No such file or directory
