We use metaclass for building on the fly new rendering pages and
we found a memory leak.
Managing with garbage collector we found that new classes are not released
for unknown reason.
Here a basic source that leak memory:
#-----------------------
print 'running server'
import nevow
from nevow import appserver
from twisted.application import service
from twisted.application import internet
class Controller(nevow.rend.Page):
def locateChild(self,context,segments):
return
type('Leaker',(nevow.rend.Page,),{'docFactory':nevow.loaders.stan(nevow.tags.h1['I
leak memory'])})(),[]
application=service.Application('leaker')
webservice = internet.TCPServer(12345,appserver.NevowSite(Controller()))
webservice.setServiceParent(application)
##AND USE THIS FOR SEE MEMORY LEAK
##import urllib
##for i in range(99999):
## urllib.urlopen('http://localhost:12345/')
#-----------------------
Is it a bug?
Is there any way to avoid the memory leak?
