This works around a nasty problem with Webpack that you can't run two
copies of the Webpack development server on the same project at the
same time (even if on different ports). The second copy doesn't fail,
it just hangs waiting for some lock, which is confusing; but even if
that were to be solved, we don't actually need the webpack development
server running to run the Casper tests; we just need bundle.js built.
So the easy solution is to just run webpack manually and be sure to
include bundle.js in the JS_SPECS entry.
As a follow-up to this change, we should clean up how test_settings.py
is implemented to not require duplicating code from settings.py.
Fixes#878.
Apparently, there are like 5 independently developed jquery-caret
plugins, none of which are great. The previous one we were using was
last modified in 2010. This new one comes from
https://github.com/acdvorak/jquery.caret and at least doesn't use
deprecated jQuery syntax and has a repository on GitHub.
This plugin is way larger than it needs to be for what it does, but we
can deal with that later.
This results in a substantial performance improvement for all of
Zulip's backend templates.
Changes in templates:
- Change `block.super` to `super()`.
- Remove `load` tag because Jinja2 doesn't support it.
- Use `minified_js()|safe` instead of `{% minified_js %}`.
- Use `compressed_css()|safe` instead of `{% compressed_css %}`.
- `forloop.first` -> `loop.first`.
- Use `{{ csrf_input }}` instead of `{% csrf_token %}`.
- Use `{# ... #}` instead of `{% comment %}`.
- Use `url()` instead of `{% url %}`.
- Use `_()` instead of `{% trans %}` because in Jinja `trans` is a block tag.
- Use `{% trans %}` instead of `{% blocktrans %}`.
- Use `{% raw %}` instead of `{% verbatim %}`.
Changes in tools:
- Check for `trans` block in `check-templates` instead of `blocktrans`
Changes in backend:
- Create custom `render_to_response` function which takes `request` objects
instead of `RequestContext` object. There are two reasons to do this:
1. `RequestContext` is not compatible with Jinja2
2. `RequestContext` in `render_to_response` is deprecated.
- Add Jinja2 related support files in zproject/jinja2 directory. It
includes a custom backend and a template renderer, compressors for js
and css and Jinja2 environment handler.
- Enable `slugify` and `pluralize` filters in Jinja2 environment.
Fixes#620.
In theory these should be the same, but in misconfigured environments
(such at Travis CI) where /etc/hosts has multiple entries for
"localhost", 127.0.0.1 is safer than "localhost".
Camo is a caching image proxy, used in Zulip to avoid mixed-content
warnings by proxying HTTP image content over HTTPS. We've been using
it in zulip.com production for years; this change makes it available
in standalone Zulip deployments.
In theory, tools like populate_db should probably be in zerver, not
zilencer, but until we migrate them out, we need to include these in
EXTRA_INSTALLED_APPS in development.
As documented in https://github.com/zulip/zulip/issues/441, Guardian
has quite poor performance, and in fact almost 50% of the time spent
running the Zulip backend test suite on my laptop was inside Guardian.
As part of this migration, we also clean up the old API_SUPER_USERS
variable used to mark EMAIL_GATEWAY_BOT as an API super user; now that
permission is managed entirely via the database.
When rebasing past this commit, developers will need to do a
`manage.py migrate` in order to apply the migration changes before the
server will run again.
We can't yet remove Guardian from INSTALLED_APPS, requirements.txt,
etc. in this release, because otherwise the reverse migration won't
work.
Fixes#441.
