Unexpected Behavior When Migrating from Python 3.7 to 3.11 with Asyncio and SQLite
I've been working on this all day and I'm learning this framework and I've searched everywhere and can't find a clear answer... During the migration of a legacy application from Python 3.7 to 3.11, I've started to notice some unexpected behavior with database interactions, particularly when using `asyncio` with SQLite... In the original setup, I was leveraging `aiosqlite` for asynchronous database operations, and everything seemed to function as expected. However, since migrating, I've been encountering this error: ``` OperationalError: database is locked ``` This error appears intermittently when I perform multiple asynchronous writes to the database. I've ensured the database connections are being properly managed using context managers. Below is a snippet of how I'm implementing the writes: ```python import asyncio import aiosqlite async def insert_data(data): async with aiosqlite.connect('mydatabase.db') as db: await db.execute('INSERT INTO my_table (column1) VALUES (?)', (data,)) await db.commit() async def main(): tasks = [insert_data(i) for i in range(100)] await asyncio.gather(*tasks) if __name__ == '__main__': asyncio.run(main()) ``` To tackle this, I've implemented a retry mechanism when catching the `OperationalError`, but it doesn't seem to resolve the issue consistently. Additionally, I’ve enabled the `PRAGMA locking_mode = EXCLUSIVE;` setting, which is supposed to help with concurrency in SQLite, but the problem persists. The application is designed to handle high-frequency write operations, so I’m concerned about this bottleneck. Any insights into why this might be happening with the migration to Python 3.11, or how I can fine-tune the database interactions to avoid this locking issue would be immensely helpful. My development environment is Linux. Is there a better approach? I'm working on a CLI tool that needs to handle this. My team is using Python for this REST API. Is there a better approach? This is part of a larger mobile app I'm building. Thanks in advance! My development environment is macOS. I'd be grateful for any help.
