Apparently, if you tried running manage.py as a non-root user that
isn't the main zulip user, you'll get a confusing Django exception
about `SECRET_KEY` not being configured.
This change provides a clean, understandable exception for this case.
Except in:
- docs/writing-bots-guide.md, because bots are supposed to be Python 2
compatible
- puppet/zulip_ops/files/zulip-ec2-configure-interfaces, because this
script is still on python2.7
- tools/lint
- tools/linter_lib
- tools/lister.py
For the latter two, because they might be yanked away to a separate repo
for general use with other FLOSS projects.
This saves us from spending 200-250ms of CPU time importing Django
again just to log that we're running a management command. On
`scripts/restart-server`, this saves us from one thundering herd of
Django startups when all the queue workers are restarted; but there's
still the Django startup for the `manage.py` process itself for each
worker, so on a machine with e.g. 2 (virtual) cores the restart is
still painful.
This causes `upgrade-zulip-from-git`, as well as a no-option run of
`tools/build-release-tarball`, to produce a Zulip install running
Python 3, rather than Python 2. In particular this means that the
virtualenv we create, in which all application code runs, is Python 3.
One shebang line, on `zulip-ec2-configure-interfaces`, explicitly
keeps Python 2, and at least one external ops script, `wal-e`, also
still runs on Python 2. See discussion on the respective previous
commits that made those explicit. There may also be some other
third-party scripts we use, outside of this source tree and running
outside our virtualenv, that still run on Python 2.
Django, by default, prints these exceptions as a giant traceback,
which is really ugly and scary to sysadmins. We really just want to
print the error message to stdout for convenient viewing by the user.
The manage.py change effectively switches the Zulip production server
to use the virtualenv, since all of our supervisord commands for the
various Python services go through manage.py.
Additionally, this migrates the production scripts and Nagios plugins
to use the virtualenv as well.
This automatically loads settings, zerver.models.* and
zerver.lib.actions.* when you start `manage.py shell`, which should
save a bit of time basically every time someone uses it.
Fixes#275.
This could potentially help with debugging exactly what happened with
some issue down the line.

This includes a hack to preserve humbug/backends.py as a symlink, so
that we don't need to regenerate all our old sessions.

I first made --traceback the default in my patches to django, but this
broke several regressions tests (when Luke built .deb packages), so he reverted that change,
and I'm putting this default into our manage.py instead
