Hello, @Nothing4You, I think I can try to do it if there is still a need for it.
But I have a little problems with aiomysql:

• When I run the make test command I get an error message:
  • python -m twine check --strict dist/*
ERROR InvalidDistribution: Cannot find file (or expand pattern): 'dist/*'
• In the aiomysql/connection.py cannot import
  • EOFPacketWrapper
  • LoadLocalPacketWrapper
  • OKPacketWrapper
  • TEXT_TYPES
  • MAX_PACKET_LEN
  • _auth
  • CR
  • escape_bytes_prefixed
  • through

It will be great if you help me with these problems so that I can start dealing with the issue faster.

@DavidRomanovizc I see that you still have your fork available, though it's last update on main (the only branch there) was in March 6th. If you could push the changes to create a reproducible environment, I think this would help in creating a solution, and others as well as I could take a look too.

Yes, I will try to update the my branch soon

Hi @DavidRomanovizc,
the Makefile has not been updated when updating the CI/test changes when it was migrated to GitHub actions, so not everything may be working properly currently.
As I'm working on macOS, it's not as easy for me to use containers for testing, as they're not natively supported, so for myself I've mostly been running pytest manually.
I've been using on my local machine e.g. MYSQL_ROOT_PASSWORD="" python -m pytest --color=yes --verbosity 2 --cov aiomysql --cov tests ./tests --mysql-address tcp.mysql80=localhost:3306 --mysql-unix-socket unix.mysql80=/tmp/mysql.sock --cov-report html -s -W always before pushing code to GitHub and letting GH actions process across different databases.
You can find the command used by GitHub actions here.
