hmm
i figured it out my self :D
no more deferToThread !
use directly the PythonThread bubu :D
def render_GET(self, request):
#d = threads.deferToThread(self.processRequest, request)
self.processRequest(request)
return server.NOT_DONE_YET
def processRequest(self, request):
t=PythonThread(target=self.doSearch, args=(request,))
t.start()
and in doSearch at the end of the thread i call:
request.finish() to finish the Twisted Web output !
PyLucene rocks :D
very nice !
keep up the good work.
Yes, for using threads other than the main thread, you must use a
PyLucene.PythonThread. For the same reasons, a PyLucene.PythonThread can only
be created from the main thread or from another PyLucene.PythonThread.
This is because libgcj's garbage collector insists on needed to initialize the
thread before it gets used. A thread cannot be used with libgcj 'after the
fact', it has to be created by libgcj.
Does processRequest start a thread for every request ?
In Chandler, where we use Twisted and PyLucene together, we created a thread
pool whose threads are Python.PyLucene thread instances and it seems to work
well.
Andi..

i am trying to run the search in a twisted web application.
in my twisted resource i have:
def render_GET(self, request):
d = threads.deferToThread(self.processRequest, request)
return server.NOT_DONE_YET
this seems not to be compatible with PyLucene.
i also tryed running a PythonThread but i get another error:
eg:
def processRequest(self, request):
print "inside process Request"
t=PythonThread(target=self.doSearch, args=(request,))
print "Starting PyThread"
t.start()
t.join()
print "Done PyThread"
request.finish()
File "/usr/lib/python2.4/site-packages/PyLucene.py", line 3479, in start
assert (current.getName() == 'MainThread' or
isinstance(current, PythonThread)), "PythonThread can only be
started from main thread of from another PythonThread"
exceptions.AssertionError: PythonThread can only be started from
main thread of from another PythonThread
Any help would be very appreciated.
10x.
