[python-ldap] Ldap connectors pool

[Tarek Ziadé]

Hey

I've been working on a pool class for ldap connectors, we're using for
the Firefox Sync server. It's a very simple class that provides a
context manager to create connectors, and offers features like:

- recycling existing connectors to avoid reconnections
- handles several connection binds
- retry a few times when the server is down or times out
- provides a max lifetime for connectors -- this is useful when you
have several ldap servers load balanced and you add a new one in the
pool: fresh connectors will use this new server **

It's been running in production for a few months now, except ** which
is to be introduced soon,

All those features are pretty generic and it seems to me that it would
be a good addition to the python-ldap project, since I haven't seen
such thing there when I started this.

If there's interest, I can isolate the pool, document it, and turn it
into a patch for Python-ldap

the code: https://hg.mozilla.org/services/server-core/file/tip/services/ldappool.py

Example of usage:

  cm = ConnectionManager('ldap://localhost')

  with cm.connection('bind', 'password') as conn:
      ... do something with conn...


Cheers
Tarek
