# Multi-Threaded Quixote Applications

Starting with Quixote 0.6, it's possible to write multi-threaded Quixote applications. In previous versions, Quixote stored the current HTTPRequest object in a global variable, meaning that processing multiple requests in the same process simultaneously was impossible.

However, the Publisher class as shipped still can't handle multiple simultaneous requests; you'll need to subclass Publisher to make it re-entrant. Here's a starting point:

    import thread
    from quixote.publish import Publisher

    [...]

    class ThreadedPublisher (Publisher):
        def __init__ (self, root_namespace, config=None):
            Publisher.__init__(self, root_namespace, config)
            self._request_dict = {}

        def _set_request(self, request):
            self._request_dict[thread.get_ident()] = request

        def _clear_request(self):
            try:
                del self._request_dict[thread.get_ident()]
            except KeyError:
                pass

        def get_request(self):
            return self._request_dict.get(thread.get_ident())

Using ThreadedPublisher, you now have one current request per thread, rather than one for the entire process.
