[Bug]: mongodb module not working with pymongo v4 #68659
Description
Context
I was migrating my mongodb server to mongodb v8. I am using the native mongodb module where there is a dependency for pymongo. In order to work with mongodb v8, the minimal version of pymongo would be v4.9. When I have tried to execute I faced an issue on the _connect function of the mongodb module.
P.S.: missed the log error since it was some days ago, sorry for it.
How to reproduce
Install any pymongo v4 in onedir of salt and try to create any user using the mongodb_user.present state using the fields password and user:
mongodb_user_myusername:
mongodb_user.present:
- name: 'myuser'
- passwd: 'mypasswd'
- host: 'localhost'
- user: 'myusername' // <- it must be here to reproduce the bug
- password: 'mypassword' // <- it must be here to reproduce the bug
- authdb: 'admin'
- database: 'admin'
- roles:
- readWrite
- dbOwnerIn your salt master, execute:
$ salt {{ minion target }} state.applyRoot cause
On pymongo v4 the function MongoClient.Database.authenticate was removed and it is still in use by the mongodb._connect function:
def _connect(
user=None, password=None, host=None, port=None, database="admin", authdb=None
):
"""
Returns a tuple of (user, host, port) with config, pillar, or default
values assigned to missing values.
"""
if not user:
user = __salt__["config.option"]("mongodb.user")
if not password:
password = __salt__["config.option"]("mongodb.password")
if not host:
host = __salt__["config.option"]("mongodb.host")
if not port:
port = __salt__["config.option"]("mongodb.port")
if not authdb:
authdb = database
try:
conn = pymongo.MongoClient(host=host, port=port)
mdb = pymongo.database.Database(conn, database)
if user and password:
mdb.authenticate(user, password, source=authdb)
except pymongo.errors.PyMongoError:
log.error("Error connecting to database %s", database)
return False
return connWorkaround
I found a workaround to allow you to work with mongodb v8 and pymongo v4.9+:
The MongoClient allows the use of mongodb URI in the host parameter. With that in mind, you probably have an idea what we can do:
mongodb_user_myusername:
mongodb_user.present:
- name: 'myuser'
- passwd: 'mypasswd'
- host: 'mongodb://myusername:mypassword@localhost'
- authdb: 'admin'
- database: 'admin'
- roles:
- readWrite
- dbOwnerWith this state, we are bypassing the MongoClient.Database.authenticate function since the user and the password are not being set but I suppose it would not be the correct way to use the mongodb module.
