Hello, Graham,
OK. I will use modwsgi group.
Answers to your questions:
My wsgi program executes "pypy-c" program in separate process.
I was trying to use both embedded and daemon modes. Config is very simple:
<VirtualHost *>
ServerName py.sandbox.lt
ServerAdmin [email protected]
ServerSignature Off
AddDefaultCharset utf-8
CustomLog /var/log/apache2/py-access.log combined
ErrorLog /var/log/apache2/py-error.log
LogLevel info
WSGIScriptAlias / /home/dalius/wsgi/py.wsgi
</VirtualHost>
py.wsgi looks like this:
from pypysandboxserver import PyPyApp
application = PyPyApp()
That's very pure and basic wsgi application. I will try version 2.X with
daemon mode and will report result.
Thank you for very quick answer.
Regards,
Dalius
