Apparently, the filters implementation was doing some sort of strange
caching, where you would need to restart the server in order to
refresh for changes to the markdown content.
We fix this by switching to just calling the render_markdown_path
function from Jinja2.
Fixes#5974.
While we already don't link to /terms anywhere on the site, they can still be
accessed if you navigate to /terms directly. Now, those routes will only be
exported on the Zulip.com service.
We should ideally provide a mechanism for deployments to specify their own
terms without modifying source code; in the interim, sites that have already
customised the provided Zulip.com terms can simply carry a patch reverting this
commit.
This needs to be deployed to both staging and prod at the same
off-peak time (and the schema migration run).
At the time it is deployed, we need to make a few changes directly in
the database:
(1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr';
(2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr';
