Subject: [execnet-dev] Problem using execnet 1.0.5 with Jython 2.5.1 on WinXP
Message-ID: <6a56a10b1003220308y27a035e9sdec32047df79379@mail.gmail.com>

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.

execnet has a test suite which you should run to narrow down the
problem. Install the py-lib[1] and run py.test in the execnet source
directory. If your having problems you can ask on the py-dev mailing
list[2].

Hello Ronny,

Thanks for having a look. I has no idea too. I tried figuring this out  
without success.

 From the traceback, it seem like the problem is with the POpenGateway  
bootstrapping, it expect that 1 byte value 1, but instead it got EOF.

Looking into the _remote_bootstrap_gateway method of the POpenGateway class  
suggests that it tries to import things, test stdout by sending 1, and  
startup exec/eval. This seem fine and work well with different versions of  
cpython (I have 2.4, 2.5, 2.6 to work), however, with Jython, it seem like  
Jython execution of sys.stdout.write('1') statement doesn't reach the  
forker side.

Trying to run similar bootstrap code from console seem to work for both  
cpython and jython.

=================================================================
C:\>echo 'print "hello"' | c:\python26\python.exe -c "import sys;  
sys.stdout.write('1'); sys.stdout.flush(); exec(eval(sys.stdin.readline()))"
1hello

C:\>echo 'print "hello"' | c:\jython2.5.1\jython.bat -c "import sys;  
sys.stdout.write('1'); sys.stdout.flush(); exec(eval(sys.stdin.readline()))"
1hello
=================================================================

I'm still wonder why does it not work inside execnet. My guess is that it  
might be a problem with Jython stdout.


Regards,



Akkratat S.
