Hello,

Thanks a lot for the contribution. Did you manage to run the tests because it's all red on travis ? https://travis-ci.org/github/noplay/python-mysql-replication/builds/754423590

(by the way I need to fix the travist integration it should have post the test result here sorry)

I tested it by referring to the documentation.

While modifying the code, I didn't consider the python 2 version.

I tried the test but the test did not finish successfully. I need your help.

mac OS(Big Sur)
python3.8

setup virtual environment 3.8

python -v venv venv
. venv/bin/activate
python setup.py install
pip install pytest

Running mysql in docker (main):

docker run --name python-mysql-replication-tests -e MYSQL_ALLOW_EMPTY_PASSWORD=true -p 3306:3306 --rm percona:latest --log-bin=mysql-bin.log --server-id 1 --binlog-format=row --gtid_mode=on --enforce-gtid-consistency=on --log_slave_updates

Run test with:

py.test -k "not test_no_trailing_rotate_event"

Docker log:

[Note] Start binlog_dump to master_thread_id(6) slave_server(1024), pos(mysql-bin.000001, 4)

py.test log:

After going so far, the test was stuck.
