Re: [IronPython] multiprocessing in 2.7
Hi Markus, Thanks for your answer. I already know that and I have started to develop my solution based on threading module. But, there is always a but, I'm working with WebBrowser and I want to run multi concurrent instances and each instance must have its own session. Unfortunately to get a session independence for each WebBrowser instance I need to get a process per instance :(. That's why I need to use multiprocess module. Maybe someone can help me to find a way to get session isolation without multiprocess usage?

Re: [IronPython] multiprocessing in 2.7
Ok,
I have patched the corresponding line:
19a20
> from System.Text import UTF8Encoding
283c284,288
< self._authkey = AuthenticationString(os.urandom(32))
---
> bytes = os.urandom(32)
> encoding=UTF8Encoding()
> if isinstance(bytes, str):
> bytes = encoding.GetBytes(bytes)
> self._authkey = AuthenticationString(bytes)
but who can I add to my IronPython the _multiprocessing module ?
--
c:\temp>ipy test-ipy-multiprocessing.py
Traceback (most recent call last):
File "test-ipy-multiprocessing.py", line 1, in
File "c:\Program Files\IronPython
2.7\lib\site-packages\multiprocessing\__init__.py", line 83, in
ImportError: No module named _multiprocessing
--
Maybe It cannot be resolved that way.

Romain

Re: [IronPython] multiprocessing in 2.7
If it is a 'C' based extension then it won't directly work with IronPython.
Maybe someone has a workaround / alternative?
Cheers,
Davy

Re: [IronPython] multiprocessing in 2.7
Hi,
First of all thanks for your answer :). But after updated my *IRONPYTHONPATH
* as follow:
set IRONPYTHONPATH=c:\Python27\Lib
I get this error:
-

Re: [IronPython] multiprocessing in 2.7
Hi Romain,
AFAIK you have to download the Python standard library separately. See e.g.
http://www.ironpython.info/index.php/Using_the_Python_Standard_Library for
examples (I've done it a while ago, so had to Google around a bit).
