[IPython-user] implementing non-blocking thread execution for something other than toolkits
Wed Feb 25 04:56:20 CST 2009
Sorry I was not very specific there.
At the moment I am working with web.py. If I do a:
run <scriptname> <portnum>
I get the output in the ipython window, but control is taken over by
the web.py process, and I lose the interactivity of the prompt.
All I would like to do is be able to run the script in the same way I
would run it using the -wthread flag, so it runs, I see output, but I
also have access to the prompt and the instance is bound to app, so I
can query the environment while it is running.
This has become crucial at the moment because the application is
hooking into another set of libraries and something very strange is
going on with the globals() variable, and I have no way of asking it
its value at various events being triggered in the script (i.e. a
request coming into the server).
web.py essentially runs as a cgi script, if that is any help.
I hope this describes what I am looking for. I am actually looking
for a generic way to do this, so it would work just as well with
something like pylons etc. but for now web.py is my puzzle as it tries
to avoid a lot of magic.
Thanks for your response,
