Shutdown handler not working

[matt24smith]

Bug Description

Code in shutdown_handler is never executed at shutdown. If a database connection is left open at time of shutdown/restart and --dev is given, a process is left hanging, preventing further use of the port.

Steps to Reproduce

For example, no message is printed upon receiving SIGINT:

from robyn import Robyn

app = Robyn(__file__)

@app.get('/')
async def index(request):
    return 'hello world'

@app.startup_handler
async def startup_handler():
    print('Starting up...')

@app.shutdown_handler
async def shutdown_handler():
    print('Shutting down...')

app.start(port=8081)

Your operating system

Linux

Your Python version (python --version)

3.12

Your Robyn version

latest

@VishnuSanal , can you have a look at this?

[VishnuSanal]

aight, I can reproduce this on my machine too.

@app.shutdown_handler
def shutdown_handler():
    print('Shutting down...')

but, works normally if I remove the async keyword. @matt24smith can you please try it & report back?

Thanks for looking into this!

My use case requires the async keyword, as I'm trying to terminate an async database connection. I can confirm that the non-async case works as expected
