Robert Gleeson created JRUBY-6409:
-------------------------------------
Summary: Open3.popen3(...) is broken in 1.9 mode
Key: JRUBY-6409
URL: https://jira.codehaus.org/browse/JRUBY-6409
Project: JRuby
Issue Type: Bug
Components: Standard Library
Affects Versions: JRuby 1.6.5
Environment: Mac OSX.
Reporter: Robert Gleeson
Assignee: Thomas E Enebo
It appears Open3.popen3(...) is broken on JRuby in 1.9 mode.
On 1.8.7, it returns three arguments (stdin, stdout, and stderr).
On 1.9.X, it returns (stdin, stdout, stderr, and a thread).
You can use the thread argument to access a Process::Status object,
and the PID of the spawned command.
To reproduce:
stdin, stdout, stderr, thr = Open3.popen3 "ls"
thr.value # => NoMethodError (called on nil)
Thanks!
