hi. When I use output=StringIO() in the tasks, it shared the same memory between the worker processes. How could I declare the isolated StringIO() for each worker? Thx a lot.

@app.task

def workon():

f = StringIO()

print(f)

f.close()

The log is:

sorry. I send multiple lines.

alas, unhappy with Celery. Love & Hate.

Can anyone suggest good video tutorial for using Celery with Django?

(I think hubert_'s StringIO() problem is just python, not celery)

(Yeah, he's definitely using the same StringIO object across all forks, because he tried to initialize it in the task method header, instead of using the recommended way of doing it in the method body.)

guyz need

SUP guyz

need help doing this next thing

@TauPan, even I packaged the stringio in the method body, not in the task header, it is the same object too.

I tried to use FORCE_EXECV , but I failed to build the billiard c extension with python 3.5.

I filed one issue: https://github.com/celery/celery/issues/3286

there is no software engineering channel but i know there are engineers here. I am starting my own IT consulting company and we want to propose and pitch to managers of a company. Assuming they agree we should build the software for them. Are to charge for consultation or say collect some initial payment before providing the Software Requirement Specification. Saying this because these could take days or so to prepare what if after this stage the

client doesn’t want the software for some reason?

hubert_: see https://www.toptal.com/python/top-10-mistakes-t... #1 is the mistake you made

hubert_: most likely, can't tell without seeing your code

oh... hm

hubert_: judging from the code in the issue there's a different problem here

if I kill -9 a child process, is there some opporunity to run some custom code on the parent process which notices and respawns?
