@elcallio maybe you have some ideas about this

It probably defaulted to Asyncio event loop in python driver, which does not work with SSL. It should work if you install libev (unless cqlsh manually selects the asyncio impl).

We should disable the fallback to asyncio, as I was trying to do in my PR to sync with upstream.

Also if we had release wheels for 3.13, it would also avoided

fruch commented Jan 19, 2025

as @Lorak-mmk mentioned, this is probably

scylladb/python-driver#330

@avikivity if it's for the toolchain, the quickest way around it, is to install libev libev-devel

@Lorak-mmk we still need sync with upstream logic as suggested in scylladb/python-driver#312
or we keep running into this, on every new version of python being released before we have wheels for it

also we should release wheels for 3.13

Thanks, I'll try that

Doesn't appear to work. Does the last released driver support libev?

No, user error here.

Now I get: Connection error: ('Unable to connect to any servers', {'127.0.0.1:9042': PermissionError(1, "Tried connecting to [('127.0.0.1', 9042)]. Last error: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1018)")})

We have a test case that is supposed to cover that

Can you share how scylla is configured ?
Which version of scylla is it ?

Does the test run with cqlsh/driver using Python 3.13? It fails for me (scylladb/scylladb#22380).

I've tested it locally with python 3.13, and everything was working as expected (those dtest passed)

I would assume some other parts of the system inside dbuild that were used to built are slightly different

I ran cqlsh after installing libev-devel and reinstalling the driver with pip. It doesn't look like it's used.

===============================================================================
WARNING: could not compile The cassandra.io.libevwrapper extension.

The C extensions are not required for the driver to run, but they add support
for libev and token-aware routing with the Murmur3Partitioner.

Linux users should ensure that GCC and the Python headers are available.

On Ubuntu and Debian, this can be accomplished by running:

    $ sudo apt-get install build-essential python-dev

On RedHat and RedHat-based systems like CentOS and Fedora:

    $ sudo yum install gcc python-devel

On OSX, homebrew installations of Python should provide the necessary headers.

libev Support
-------------
For libev support, you will also need to install libev and its headers.

On Debian/Ubuntu:

    $ sudo apt-get install libev4 libev-dev

On RHEL/CentOS/Fedora:

    $ sudo yum install libev libev-devel

On OSX, via homebrew:

    $ brew install libev
