[execnet-dev] Problem using execnet 1.0.5 with Jython 2.5.1 on WinXP

[Akkratat Sintavarattana]

Hello,

I have problem using execnet 1.0.5 to execute the code within Jython 2.5.1
on WinXP platform. I wonder whether anyone experience the same problem. I
include the simple test program below with it's output. Initially, I tried
to fixed this myself without success. I thought it might be the problem with
the Jython and not execnet. But since the documentation states that it's
tested with Jython 2.5.1, I guess it work on platforms other than Windows.
Has anyone gotten this to work Windows?

If you want me to help test the experimented code or something, I'm willing
to help. This is a very useful and powerful library !

Thanks for creating this.

=== Test Code ===
===========================================================
import execnet

code = """
import sys
channel.send(sys.version)
"""
specs = (
    r'popen//python=c:\python25\python.exe',
    r'popen//python=c:\python26\python.exe',
    r'popen//python=jython.bat',
)
# my jython is in c:\jython2.5.1, which is set in PATH

for spec in specs:
    gw = execnet.makegateway(spec)
    ch = gw.remote_exec(code)
    print ch.receive()
    print '-' * 70
