<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>
