This fixes some tracebacks I got while testing the Zulip htpasswd SSO
functionality.
I think that this stopped working as a result of the Jinja2 migration.
We would like to know which kind of authentication backends the server
supports.
This is information you can get from /login, but not in a way easily
parseable by API apps (e.g. the Zulip mobile apps).
This prototype from Dropbox Hack Week turned out to be too inefficient
to be used for realms with any significant amount of history, so we're
removing it.
It will be replaced by https://github.com/zulip/zulip/pull/673.
This reverts commit e985b57259.
This commit will break production when we next do a release, because
we haven't done a migration to create Attachment objects for
previously uploaded files.
For a long time, rest_dispatch has had this hack where we have to
create a copy of it in each views file using it, in order to directly
access the globals list in that file. This removes that hack, instead
making rest_dispatch just use Django's import_string to access the
target method to use.

generate_random_token used to return a value of type six.binary_type
and its return type was annotated as `str`. This commit fixes that
by making it return a value of type `six.text_type` and updating
the annotation accordingly.
Also fix clashing annnotations.
This changes the type annotations for the cache keys in Zulip to be
consistently text_type, and updates the annotations for values that
are used as cache keys across the codebase.
Previously, uploaded files were served:
* With S3UploadBackend, via get_uploaded_file (redirects to S3)
* With LocalUploadBackend in production, via nginx directly
* With LocalUploadBackend in development, via Django's static file server
This changes that last case to use get_uploaded_file in development,
which is a key step towards being able to do proper access control
authorization.
Does not affect production.
Also, fixed a a small type annotation in users.py because email must
be a string because emails don't support UTF-8 at this time (according
a comment in gravatar_hash in avatar.py).
Previously, api_fetch_api_key would not give clear error messages if
password auth was disabled or the user's realm had been deactivated;
additionally, the account disabled error stopped triggering when we
moved the active account check into the auth decorators.
The security model for deactivated users (and users in deactivated
realms) being unable to access the service is intended to work via two
mechanisms:
* All active user sessions are deleted, and all login code paths
(where a user could get a new session) check whether the user (or
realm) is inactive before authorizing the request, preventing the
user from accessing the website and AJAX endpoints.
* All API code paths (which don't require a session) check whether the
user (and realm) are active.
However, this security model was not implemented correctly. In
particular, the check for whether a user has an active account in the
login process was done inside the login form's validators, which meant
that authentication mechanisms that did not use the login form
(e.g. Google and REMOTE_USER auth) could succeed in granting a session
even with an inactive account. The Zulip homepage would still fail to
load because the code for / includes an API call to Tornado authorized
by the user's token that would fail, but this mechanism could allow an
inactive user to access realm data or users to access data in a
deactivated realm.
This fixes the issue by adding explicit checks for inactive users and
inactive realms in all authentication backends (even those that were
already protected by the login form validator).
Mirror dummy users are already inactive, so we can remove the explicit
code around mirror dummy users.
The following commits add a complete set of tests for Zulip's inactive
user and realm security model.
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.
To avoid the potential for introducing regressions here, we carefully
pass a default to REQ or not based on how the existing webhook's
parsing code worked. In the longer term, we'll want to make the
behavior consistent.
This integration relies on the Teamcity "tcWebHooks" plugin which is
available at
https://netwolfuk.wordpress.com/category/teamcity/tcplugins/tcwebhooks/
It posts build fail and success notifications to a stream specified in
the webhook URL.
It uses the name of the build configuration as the topic.
For personal builds, it tries to map the Teamcity username to a Zulip
username, and sends a private message to that person.
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.
Add a function email_allowed_for_realm that checks whether a user with
given email is allowed to join a given realm (either because the email
has the right domain, or because the realm is open), and use it
whenever deciding whether to allow adding a user to a realm.
This commit is not intended to change any behavior, except in one case
where the Zulip realm's domain was not being converted to lowercase.
The previous implementation didn't work because HomepageForm rejected
the email as not having a domain. Additionally, the logic in
accounts_register didn't work with Google auth because that code path
doesn't pass through accounts_home. Since whether there's a unique
open realm for the server is effectively a configuration property, we
can fix the bug and make the logic clearer by moving it into the
"figure out the user's realm" function.
The browser registers for events via loading the home view, not this
interface, and this functionality is available via the API-format
register route anyway.
This makes it possible to use DevAuthBackend when doing
performance/scalability testing on Zulip with many thousands of users.
It's unlikely that anyone testing this backend will find it valuable
to have more than 100 login buttons on the same page, and if they do,
they can always just change this limit.
Thanks to @dbiollo for the suggestion!
Previously we only did this when new human users were created via the
login process, which meant the management command to create a user did
not add the user to default streams (for example) and any future code
that might want to register a new Zulip user (such as the LDAP
integration) would need to import views/__init__.py in order to
properly set this up.
In b59b5cac35, we upgraded our Google
Oauth code to support new python-requests, but because Ubuntu precise
still has old python-requests, this broke the codepath for older
systems.
requests 1.0 changed response.json attribute to response.json()
instancemethod. The code wasn't updated to match that change,
causing a TypeError when attempting to use the Google OAuth
Authenticator backend.
This is fixed simply by using response.json() instead of response.json.
These features are in most cases possible to setup directly via our
GitHub services integration UI, and the customers aren't using Zulip
anymore, so this is worth doing to clean up the code.
