celery run old code and new code at same time

[steinliber]

Hi,all!!
I use celery to run my django task. After i change my code yesterday, i find celery run both my old code and new code.So when i pass same parameter to task, sometimes i get error, sometimes it excutes successfully. i have tryd purge, restart celery, but all uesless.
Can anyone tell me what happened

Purge should have purged everything (celery -A projectName purge), but if you're using the Django Database Scheduler in Django Admin area, and have not removed unwanted tasks using this, it might be re-instating them.
I'm not an expert, just trying to help.

I faced with the same problem today. The steps that helped me:

1. Stop all workers.
2. Clear python cache in project dir. This command will clear pychache content across all dirs:
   find . | grep -E "(__pycache__|\.pyc|\.pyo$)" | xargs rm -rf
3. Restart a server.

Same problem. The above solution is not working for me. Any help?

Would love to have a solution on that. That'a a big problem for me

Is there any fix for this issue? Or is there any workaround to stop making celery pick up old code.

[pkrakesh]

Make sure that you don't have any commented codes in any task. If there is any, delete it. This made my head spin and at last I found the problem was this.

@pkrakesh was the issue resolved after that? For me when i pushed new changes in task the celery is exicuting old code. If this issue got resolved do let me know thank you.

So, I found that after killing (control+c) the process, it was still on the background. I had hundreds! so I killed it all and it started to get the new code again

I have encountered with the same issue once, there may be chances that celery is running somewhere else too, please be sure your task is executing by the same celery worker.

I am running a email queue task using celery and rabbitmq as broker when i pushed new changes to the code celery is picking old code and failing the task when the task is triggered again then its taking new code. So is there anyway to resolve this , only new changes in task is getting affected and getting failed.
