Re: Django Celery throwing runtime warnings for naive times

2014-04-28 Thread John DeRosa

I suggest you file a ticket in the celery project 
(https://github.com/celery/celery/issues), or ask for help on the #celery IRC 
channel. (See 
http://celery.readthedocs.org/en/latest/getting-started/resources.html for 
"help" resources...) They'd be more profitable avenues for you, given the code 
path that's in the stack dump.

Django Celery throwing runtime warnings for naive times

2014-04-28 Thread heidi


  
I run an online game with Django 1.6 and Celery 3.1.11. Kombu is 3.0.15.

Recently I had problems with Celery and DST, so I decided to run the whole 
site on UTC and save myself the bother of worrying about timezones.

The relevant parts of my settings.py:

TIME_ZONE = 'UTC'
USE_TZ = True
CELERY_ENABLE_UTC = True
CELERY_TIMEZONE = 'UTC'

Now, whenever I send *any* delayed task, I see a bunch of RuntimeWarnings 
that complain about naive datetimes. I went into my settings.py and turned 
this into an exception, and this is the traceback that resulted:

[2014-04-18 15:03:49,748: INFO/MainProcess] Received task: sometask[sometaskid]

As you can see, none of the traceback is due to my code, so I do not know 
how to proceed. I could merely leave the warnings in (if I recall 
correctly, Celery defaults time offsets to the CELERY_TIMEZONE in 
settings.py, and this is what I want anyway) but my OCD is screaming out at 
me to get this fixed. Plus, I can't ctrl-F to find any warning that *are*due to 
my code.

Any advice?
