For more information about SCGI and mod_scgi for Apache1/Apache2, see <http://www.mems-exchange.org/software/scgi/>. For more information about the Web Server Gateway Interface, see <http://www.python.org/peps/pep-0333.html>. Example usage: #!/usr/bin/env python import sys from myapplication import app # Assume app is your WSGI application object from scgi import WSGIServer ret = WSGIServer(app).run() sys.exit(ret and 42 or 0) See the documentation for WSGIServer for more information. About the bit of logic at the end: Upon receiving SIGHUP, the python script will exit with status code 42. This can be used by a wrapper script to determine if the python script should be re-run. When a SIGINT or SIGTERM is received, the script exits with status code 0, possibly indicating a normal exit. Example wrapper script: #!/bin/sh STATUS=42 while test $STATUS -eq 42; do python "$@" that_script_above.py STATUS=$? done z Allan Saddi <allan@saddi.com>z $Revision$� N)�BaseSCGIServer� Connection� NoDefault)� PreforkServer� WSGIServerc �8 � e Zd ZdZeddddej dfd�Zd� ZdS )r a SCGI/WSGI server. For information about SCGI (Simple Common Gateway Interface), see <http://www.mems-exchange.org/software/scgi/>. This server is similar to SWAP <http://www.idyll.org/~t/www-tools/wsgi/>, another SCGI/WSGI server. It differs from SWAP in that it isn't based on scgi.scgi_server and therefore, it allows me to implement concurrency using threads. (Also, this server was written from scratch and really has no other depedencies.) Which server to use really boils down to whether you want multithreading or forking. (But as an aside, I've found scgi.scgi_server's implementation of preforking to be quite superior. So if your application really doesn't mind running in multiple processes, go use SWAP. ;) N)� localhosti� Tc � � t j | |||dd|||||�� � dD ] } | | v r| | = � t j | ft | fd�| �� dS )a scriptName is the initial portion of the URL path that "belongs" to your application. It is used to determine PATH_INFO (which doesn't seem to be passed in). An empty scriptName means your application is mounted at the root of your virtual host. environ, which must be a dictionary, can contain any additional environment variables you want to pass to your application. bindAddress is the address to bind to, which must be a string or a tuple of length 2. If a tuple, the first element must be a string, which is the host name or IPv4 address of a local interface. The 2nd element of the tuple is the port number. If a string, it will be interpreted as a filename and a UNIX socket will be opened. If binding to a UNIX socket, umask may be set to specify what the umask is to be changed to before the socket is created in the filesystem. After the socket is created, the previous umask is restored. allowedServers must be None or a list of strings representing the IPv4 addresses of servers allowed to connect. None means accept connections from anywhere. loggingLevel sets the logging level of the module-level logger.
