"""The config_factory takes a dictionary containing the command line arguments
|
|
and should return the same dictionary after modifying any of the settings it wishes.
|
|
At the very least the config_factory must set the 'app_factory' key in the returned
|
|
argument dictionary, which should be the dotted path to the function which will be
|
|
called to actually return the wsgi application which will be served. Also, the
|
|
config_factory can look at the 'args' key for any additional positional command-line
|
|
arguments that were passed to spawn, and modify the configuration dictionary
|
|
based on it's contents.
|
|
|
|
Return value of config_factory should be a dict containing:
|
|
app_factory: The dotted path to the wsgi application factory.
|
|
Will be called with the result of factory_qual as the argument.
|
|
host: The local ip to bind to.
|
|
port: The local port to bind to.
|
|
num_processes: The number of processes to spawn.
|
|
num_threads: The number of threads to use in the threadpool in each process.
|
|
If 0, install the eventlet monkeypatching and do not use the threadpool.
|
|
Code which blocks instead of cooperating will block the process, possibly
|
|
causing stalls. (TODO sigalrm?)
|
|
dev: If True, watch all files in sys.modules, easy-install.pth, and any additional
|
|
file paths in the 'watch' list for changes and restart child
|
|
processes on change. If False, only reload if the svn revision of the
|
|
current directory changes.
|
|
watch: List of additional files to watch for changes and reload when changed.
