IO.popen4 reading from the wrong socket results in wrong error message
----------------------------------------------------------------------
Key: JRUBY-4932
URL: http://jira.codehaus.org/browse/JRUBY-4932
Project: JRuby
Issue Type: Bug
Reporter: Roger Pack
Assignee: Thomas E Enebo
Priority: Minor
>> p,i,o,e = IO.popen4("..\\vendor\\gocr048.exe")
=> [444, #<IO:0x10980e7>, #<IO:0xedbe39>, #<IO:0x639bf1>]
irb(main):002:0> r.read
Java::JavaNioChannels::NonReadableChannelException:
#<Java::JavaNioChannels::NonReadableChannelException:0xc017e9>
from sun.nio.ch.FileChannelImpl.read(FileChannelImpl.java:134)
from
org.jruby.util.io.ChannelDescriptor.read(ChannelDescriptor.java:542)
It probably wants to look like this:
>> i.read
IOError: not opened for reading
from (irb):7:in `read'
Since that's what MRI's popen3 input streams do.
Cheers!
