<h1 class="title">Multi-Threaded Quixote Applications</h1>
<p>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.</p>
<p>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:</p>
<pre class="literal-block">
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())
</pre>
<p>Using ThreadedPublisher, you now have one current request per thread,
rather than one for the entire process.</p>
