when installing MariaDB Server 10.5.17 or 10.5.18 on a CentOS 7 host, the mariadb connector is throwing this error to us during our connect.

>10.6 is not throwing this issue.

During initialization mariadb module loads the client version via mysql_get_client_info into mariadbapi_version.

mysql_get_client_info uses MARIADB_PACKAGE_VERSION macro, which is defined in mariadb_version.h. It has the format major.minor.patch.

Obviously someone changed this to another format when building ES packages, instead of 3.3.3 it was changed to 10.5.17-12,which explains this issue.

This change in ES also has other impacts, e.g. it is impossible to determine if a feature is supported by checking the client version (10 is always > 3)

cole.busby Could you please attach output from mariadb_config and the include file mariadb_version.h from ES installation?

MariaDB Connector/Python v1.1.3 requires MariaDB Connector/C >= 3.2.4, actual version (v.1.1.5) requires 3.3.1 (3.2 is discontinued).

in mariadb_posix.py (v1.1.3)
required_version = "3.2.4"

MariaDB ES 10.5.x ships Connector/C 3.1 - which is < 3.2.4. If the installation passed, it indicates that the C/C version was modified (and bumped) and all further capability checks (in mostly every product) will return wrong results.

The problem is that MariaDB Connector/Python was built with the required minimum version of Connector/C, but an older connector/c client library is in default path.

Comment by Georg Richter [ 2023-01-16 ]

Not a bug, since the correct version of Connector/C is not in default place, so the unsupported Connector/C shared library from ES will be loaded instead.

Fix for CONPY-244 will now throw an exception during module initialization if an incompatible library was loaded.

This is Connector/C bug, it was returning a wrong version to the Connector/Python.

Fixed in https://github.com/mariadb-corporation/mariadb-connector-c/commit/d204e83104222844251b221e9be7eb3dd9f8d63d
