Switch to openstackdocstheme 2.2.1 and reno 3.1.0 versions. Using these versions will allow especially: * Linking from HTML to PDF document * Allow parallel building of documents * Fix some rendering problems Update Sphinx version as well. Disable openstackdocs_auto_version to not auto-version the documents. Disable openstackdocs_auto_name to use 'project' variable as name. Change pygments_style to 'native' since old theme version always used 'native' and the theme now respects the setting and using 'sphinx' can lead to some strange rendering. Remove docs requirements from lower-constraints, they are not needed during install or test but only for docs building. openstackdocstheme renames some variables, so follow the renames before the next release removes them. A couple of variables are also not needed anymore, remove them.

ldappool
A simple connector pool for python-ldap.
The pool keeps LDAP connectors alive and let you reuse them, drastically reducing the time spent to initiate a ldap connection.
The pool has useful features like:
- transparent reconnection on failures or server restarts
- configurable pool size and connectors timeouts
- configurable max lifetime for connectors
- a context manager to simplify acquiring and releasing a connector
You need python-ldap in order to use this library
Quickstart
To work with the pool, you just need to create it, then use it as a context manager with the connection method:
from ldappool import ConnectionManager
cm = ConnectionManager('ldap://localhost')
with cm.connection('uid=adminuser,ou=logins,dc=mozilla', 'password') as conn:
.. do something with conn ..The connector returned by connection is a LDAPObject, that's binded to the server. See https://pypi.org/project/python-ldap/ for details on how to use a connector.
It is possible to check the state of the pool by representing the pool as a string:
from ldappool import ConnectionManager
cm = ConnectionManager('ldap://localhost', size=2)
.. do something with cm ..
print(cm)This will result in output similar to this table:
+--------------+-----------+----------+------------------+--------------------+------------------------------+
| Slot (2 max) | Connected | Active | URI | Lifetime (600 max) | Bind DN |
+--------------+-----------+----------+------------------+--------------------+------------------------------+
| 1 | connected | inactive | ldap://localhost | 0.00496101379395 | uid=tuser,dc=example,dc=test |
| 2 | connected | inactive | ldap://localhost | 0.00532603263855 | uid=tuser,dc=example,dc=test |
+--------------+-----------+----------+------------------+--------------------+------------------------------+ConnectionManager options
Here are the options you can use when instanciating the pool:
- uri: ldap server uri [mandatory]
- bind: default bind that will be used to bind a connector. default: None
- passwd: default password that will be used to bind a connector. default: None
- size: pool size. default: 10
- retry_max: number of attempts when a server is down. default: 3
- retry_delay: delay in seconds before a retry. default: .1
- use_tls: activate TLS when connecting. default: False
- timeout: connector timeout. default: -1
- use_pool: activates the pool. If False, will recreate a connector each time. default: True
The uri option will accept a comma or whitespace separated list of LDAP server URIs to allow for failover behavior when connection errors are encountered. Connections will be attempted against the servers in order, with retry_max attempts per URI before failing over to the next server.
The connection method takes two options:
- bind: bind used to connect. If None, uses the pool default's. default: None
- passwd: password used to connect. If None, uses the pool default's. default: None
