MariaDB Python OperationalError: This feature is not implemented or disabled - mariadb

Question

I've compiled and installed Python 3.10.9 (from .tar) and mariadb-c-connector (from official Github repo) on my Debian 11 (bullseye) machine.
I also installed: ufw, fail2ban, mariadb-server, mariadb-client.
Now if i install mariadb in my Python pipenv and run i got the error: mariadb.OperationalError: This feature is not implemented or disabled.
On my Manjaro it works fine. This is how i create a connection to the database.
def connect(self):
if self.conn:
return
# Connect to MariaDB Platform
try:
self.conn = mariadb.connect(
user=self.user,
password=self.password,
host=self.host,
port=self.port,
database=self.database,
reconnect=True,
)
except mariadb.Error as e:
log.exception(f"Error connecting to MariaDB Platform: {e}")
self.conn = None
return
What i do wrong or what is missing?
Thank you in advance.

Answer 1

This is the check in source code:
#if MARIADB_PACKAGE_VERSION_ID > 30301
if (mysql_optionsv(self->mysql, MARIADB_OPT_STATUS_CALLBACK, MrdbConnection_process_status_info, self))
goto end;
#endif
It fails, since mysql_optionsv doesn't support the option MARIADB_OPT_STATUS_CALLBACK and returns error CR_NOT_IMPLEMENTED.
Update (after more details were added to the original question):
So it looks like you built (installed) the mariadb module with the correct required Connector/C version (> 3.3.1) , however there is an older Connector/C version in your default library path libmariadb.so.3 => /lib/x86_64-linux-gnu/libmariadb.so.3 (which was likely installed with package libmariadb-dev)

Answer 2

I had the same problem in a docker environment with python 3.11-slim and mariadb 10.11-rc. I also installed mariadb==1.1.5.post3.
I updated the MariaDB Connector/C using the following instruction.
Here's what I did in my Dockerfile
RUN apt-get update && apt-get install -y gcc curl wget
RUN wget https://downloads.mariadb.com/MariaDB/mariadb_repo_setup
RUN chmod +x mariadb_repo_setup
RUN ./mariadb_repo_setup \ --mariadb-server-version="mariadb-10.6"
RUN apt install -y libmariadb3 libmariadb-dev
These commands helped me update the library to the new version.
In my connection code, I also replaced host with the name of the service from the docker-compose.yml file. In my case it will be db
from os import getenv
import mariadb
con = mariadb.connect(
host='db',
user=getenv('DB_USER', default=''),
password=getenv('DB_PASS', default=''),
database=getenv('DB_NAME', default=''),
)
cur = con.cursor()
I hope these commands help resolve the issue in your environment
