I believe I have found a bug - my site was working great prior to adding
support for localization/timezones and if a user encountered a 500
internal server error, I'd get an email about it and could fix it. I
added support for timezones, and **stopped getting the alert emails** --
and the users are no longer sent to my 500 page.
Here's some information:
* debug=True causes things to work correctly (no email sent, debug info
displayed to the user)
* this does not happen in a development environment at all as far as I can
tell
* I am using Channels and Daphne to serve content behind an Nginx reverse
proxy
* When 500 errors happen, the user gets redirected to a very generic
Daphne "exception inside application" page. Before you blame this on
Daphne, please keep reading...
* The error log traceback points to `site-
packages/django/templatetags/tz.py`
If I change this class to look as follows:
{{{
def render(self, context):
try:
with timezone.override(self.tz.resolve(context)):
output = self.nodelist.render(context)
return output
except:
return self.nodelist.render(context)
}}}
the correct 500 error page is rendered and the email goes out to me
telling me where the error occurred. That suggests to me that something
in timezone.override isn't working as it should be.
I could just make a PR with this but I am not really sure what
consequences this change has.
I know there's a lack of info in this, and I apologize in advance. Because
I only see this issue on my production server, I have to take my whole
site down to try to test and troubleshoot it.
