QUESTION
I have a project that worked on ubuntu 16.04 with python 3.6 but now we are trying to make it run on ubuntu 20.04 with same python version. I need to install all requirements on the venv and apparently its only mysqlclient==1.3.12 that fails.
Went through lots of articles on stackoverflow but none of them seem to solve the problem.
Error for pip3 install mysqlclient==1.3.12
...ANSWER
Answered 2021-Oct-01 at 14:15You're using old mysqlclient 1.3.12 with new MySQL 8. Either you need to downgrade MySQL to version 5.6. Or you need to use later mysqlclient.
The incompatibility was fixed in commit a2ebbd2 on Dec 21, 2017 so you need a later version of mysqlclient.
mysqlclient 1.3.13 was released on Jun 27, 2018. Try it or any later version.
QUESTION
i have a weird error and can't find a fix for it. I'm searching since weeks for a solution, I found a few other stackoverflow articles about it, but sadly they doesn't helped me. Aside from this, I can't find many articles in google about my problem. I even tried to switch MySQL drivers to avoid this error, but it doesn't help. It's really frustrating, because it looks like there's no reason for this error.
I tried aiomysql, asyncmy and even peewee-async. I'm using Python 3.8 on Linux Debian 10. And I found a Pull Request that "should" help to solve this error for aiomysql, but it was never finished/published/whatever.
So everytime I build a async mysql connection, execute a few queries and try to close the connection after it, I still get everytime the error An open stream object is being garbage collected; call "stream.close()" explicitly
So first of all, that's my function to start the async connection:

QUESTION
i have a problem. I want to make a task for my giveaway-bot for checking if a giveaway ended. So I created a task for doing it and it runs many lines of code and everything is working. But I noticed that my code is pretty slow. Can anyone help me and say what I can improve and how to speed this up?
I use aiomysql for connecting to my mariadb database and time.time() for checking the code speed.
Sorry if I'm making something wrong, I'm new on this site, feel free to comment if you need anything from me. :)

...ANSWER
Answered 2021-Aug-10 at 22:15I see you have a lot of quarry's in the your loop that's the reason why its so slow. cant you make one big quarry? your mysql database will be quicker in sorting data of python.
maybe some hints to begin:
- i see you sort out non nitro account but i dont see it in your first quarry.
- i see you select all messages, maybe only take the messages after the start of the give away? so your script doesn't have to go through all the data.
- almost all if statements (about sorting data) can be written in a quarry's
im not that good whit databases myself, but if i can see your database and specifically know what you want from the query (i suspect a list of possible winners), maybe i can help. and how long takes this script right now?

ANSWER
Answered 2021-Jun-26 at 09:45The problem seems to be that aiomysql is trying to close its connection after the event loop has closed. I could make the code in the question work by ensuring that the session was closed and the engine disposed.

QUESTION
I am writing a REST API using aiohttp.
Some of the coroutines need to call the database using the aiomysql library. The documentation for aiomysql has the following example:
ANSWER
Answered 2020-Nov-11 at 15:21loop argument should go.
aiomysql should be updated to don't accept the loop.
You can just skip loop=... in your code right now because aiomysql.connect() has the default loop=None value for the argument.
In general, asyncio.get_event_loop() will be deprecated; asyncio.get_running_loop() is recommended for the usage from an async code when needed. Passing an explicit loop to asyncio API is deprecated starting from Python 3.8.

Install aiomysql
You can use aiomysql like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
