Cannot connect to local database in 2024a

Bug Report

I cannot connect to my local mysql database

Description

I couldn't see in the documentation https://datajoint.github.io/datajoint-docs-original/matlab/index.html how I am supposed to connect but running dj.conn() does not seem to work, regardless of setting name, pw, host.

Reproducibility

Include:

• OS (WIN

• MATLAB Version 2024a

• MySQL Version 8.0.38

• MySQL Deployment Strategy (local-native

• DataJoint Version 3.5.1

• Minimum number of steps to reliably reproduce the issue dj.conn()

• Complete error stack as a result of evaluating the above steps

Error using mym SSL connection error: unknown error number

Additional Research and Context

I solved this by running the following on my mysql connection on localhost:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newrootpassword'

and then connecting through dj with TLS set to false.

I just ran into this issue as well, it is because inside of conn.m

elseif ~isstruct(use_tls)
    use_tls = 'none';

And the string 'none' is not handled. If you comment this out and or/change 'none' to 'false', it will work. Maybe one of the maintainers can let us know if that is a problematic fix, happy to make a PR if it seems useful.

Thank you, @stephenholtz . We will review and merge. As you know, we are focusing on datajoint-python and your contribution to datajoint-matlab is most appreciated.

Gotcha, I'll try to do it over the weekend
