python regex negative lookahead assertions problems
Hi List,
I'm trying to match lines in python using the re module.
The end goal is to have a regex which enables me to skip lines which have ok
and warning in it.
But for some reason I can't get negative lookaheads working, the way it's
explained in http://docs.python.org/library/re.html;.
Consider this example:
Python 2.6.4 (r264:75706, Nov 2 2009, 14:38:03)
[GCC 4.4.1] on linux2
Type help, copyright, credits or license for more information.
import re
line='2009-11-22 12:15:441 lmqkjsfmlqshvquhsudfhqf qlsfh qsduidfhqlsiufh
qlsiuf qldsfhqlsifhqlius dfh warning qlsfj lqshf lqsuhf lqksjfhqisudfh
qiusdfhq iusfh'
re.match('.*(?!warning)',line)
_sre.SRE_Match object at 0xb75b1598
I would expect that this would NOT match as it's a negative lookahead and
warning is in the string.
Thanks,

SimpleXMLRPCServer and creating a new object on for each new client request.
Hi list,
My goals is to have concurrent and separated client sessions using xmlrpc.
Initially my though was that SimpleXMLRPCServer was able to create a new
object instance for each incoming request.
But this doesn't appear to be the case, unless I'm overlooking something,
if so please point me out.
Concider following simplified code
#!/usr/bin/python
from SimpleXMLRPCServer import SimpleXMLRPCServer
from SimpleXMLRPCServer import SimpleXMLRPCRequestHandler
import random
# Restrict to a particular path.
class RequestHandler(SimpleXMLRPCRequestHandler):
rpc_paths = ('/RPC2',)
# Create a simple example class
class Randomizer:
def __init__(self):
self.random=random.randrange(0,10)
def show_random(self):
return self.random
# Create server
server = SimpleXMLRPCServer((localhost,
8000),requestHandler=RequestHandler,allow_none=1)
server.register_introspection_functions()
server.register_instance(Randomizer())
server.serve_forever()
I start python interactively:
import xmlrpclib
session1=xmlrpclib.ServerProxy('http://localhost:8000')
session2=xmlrpclib.ServerProxy('http://localhost:8000')
print session1.show_random()
13930
print session2.show_random()
13930
I though that session1 and session2 would be 2 different Randomizer objects
each having a different result for self.random
But as the example shows this is not the case.
How can I solve this?
Thanks
Jelle
