I'm writing an application that interacts with ldap, and I'm looking
for advice on how to handle the connection. Specifically, how to
close the ldap connection when the application is done.
I wrote a class to wrap an LDAP connection, similar to this:
import ldap
import ConfigParser
class MyLDAPWrapper(object):
def __init__(self):
config = ConfigParser.SafeConfigParser()
config.read('sample.conf')
uri = config.get('LDAP', 'uri')
user = config.get('LDAP', 'user')
password = config.get('LDAP', 'password')
self.ldapClient = ldap.initialize(uri)
self.ldapClient.simple_bind_s(user, password)
My question is this: what is the best way to ensure the ldap connection
gets closed when it should? I could write an explicit close() method,
but that seems a bit messy; there would end up being lots of calls to
close() scattered around in my code (primarily inside exception handlers.)
Or I could write a __del__ method:
def __del__(self):
self.ldapClient.unbind_s()
This seems like a much cleaner solution, as I don't ever have to worry
about closing the connection; it gets done automatically.
I haven't ever used __del__ before. Are there any 'gotchas' I need to
worry about?
Thanks!
