Trace python asyncio tasks exceptions live
Project description
aio-live-tasks-exceptions
Trace python asyncio tasks exceptions live!
Installation
Install the last released version using pip
:
python3 -m pip install -U aio-live-task-traces
Or install the latest version from sources:
git clone git@github.com:matan1008/aio-live-task-traces.git
cd aio-live-task-traces
python3 -m pip install -U -e .
Usage
Usually, if you run a task that throws exception using asyncio you will not be aware of the exception until the task is awaited or deleted. For example:
import asyncio
async def faulty_task():
raise Exception('foo')
async def main():
task = asyncio.create_task(faulty_task())
await asyncio.sleep(3600)
await task
if __name__ == '__main__':
# The exception will be printed after 3600 seconds
asyncio.run(main())
This package, will wrap each task you run so the exception will be traced the moment it raises:
import asyncio
from aio_live_task_traces import set_live_task_traces
async def faulty_task():
raise Exception('foo')
async def main():
set_live_task_traces(True)
task = asyncio.create_task(faulty_task())
await asyncio.sleep(3600)
await task
if __name__ == '__main__':
# The exception will be printed both immediately and after 3600 seconds
asyncio.run(main())
