Re: Django gracefully shutdown

[fuxter fuxter]

I found this solution pretty easy and to my likings:

$ uwsgi ... --touch-reload /var/run/any_file_actually.pid ... # launching 
uwsgi
$ touch /var/run/any_file_actually.pid # anytime i want to reload all the 
python code

I'm using using uWSGI in master mode with handfull of small sites and this 
approach reloads all workers, so it might not be for everybody.

PicklingError: Can't pickle : it's not the same object as pytz._UTC

[fuxter fuxter]

Hello all,

Did anybody encounter the error above after upgrading to 1.4 and switching 
to timezones? Some pages start 500 randomly, really randomly. I've tried 
switching to pickle from cPickle. I've tried changing pickle protocols in 
the memcached module. I've tried pylibmc. All the same. As a half measure 
I'm forced to use locmem for now.

Couldn't google something useful on the topic apart from problems with lazy 
objects with pickling.

Some info:
Django 1.4
pytz pytz==2012b
python-memcached==1.48
