Anders Kaseorg c734bbd95d python: Modernize legacy Python 2 syntax with pyupgrade.
Generated by `pyupgrade --py3-plus --keep-percent-format` on all our
Python code except `zthumbor` and `zulip-ec2-configure-interfaces`,
followed by manual indentation fixes.

Mateusz Mandera 9911c6a0f0 rate_limiter: Put secs_to_freedom as message when raising RateLimited.
That's the value that matters to the code that catches the exception,
and this change allows simplifying the plumbing somewhat, and gets rid
of the get_rate_limit_result_from_request function.
2020-04-08 10:29:18 -07:00
Mateusz Mandera 8069133f88 rate_limit: Remove __str__ methods of RateLimitedObjects.
These were clunky from the start and are no longer used, as keys are now
used directly for logging purposes.
2020-03-22 18:42:35 -07:00
Mateusz Mandera 4e9f77a6c4 rate_limit: Adjust keys() of some RateLimitedObjects.
type().__name__ is sufficient, and much readable than type(), so it's
better to use the former for keys.
We also make the classes consistent in forming the keys in the format
type(self).__name__:identifier and adjust logger.warning and statsd to
take advantage of that and simply log the key().
2020-03-22 18:42:35 -07:00
Mateusz Mandera 2c6b1fd575 rate_limit: Rename key_fragment() method to key(). 2020-03-22 18:42:35 -07:00
Mateusz Mandera 9c9f8100e7 rate_limit: Add the concept of RateLimiterBackend.
This will allow easily swapping and using various implementations of
rate-limiting, and separate the implementation logic from
RateLimitedObjects.
2020-03-22 18:42:35 -07:00
Mateusz Mandera 85df6201f6 rate_limit: Move functions called by external code to RateLimitedObject. 2020-03-22 18:42:35 -07:00
Steve Howell 62fb3ad801 refactor: Move validate_email_not_already_in_realm.
We move this to email_validation.py.

Steve Howell 4f5b07a7e6 refactor: Extract zerver/lib/email_validation.py. 2020-03-06 11:53:22 -08:00
Steve Howell 57f1aa722c refactor: Rename validate_email_for_realm.
Now called:

    validate_email_not_already_in_realm

We have a separate validation function that
makes sure that the email fits into a realm's
domain scheme, and we want to avoid naming
confusion here.

rht 41e3db81be dependencies: Upgrade to Django 2.2.10.
Django 2.2.x is the next LTS release after Django 1.11.x; I expect
we'll be on it for a while, as Django 3.x won't have an LTS release
series out for a while.

Because of upstream API changes in Django, this commit includes
several changes beyond requirements and:

* urls: django.urls.resolvers.RegexURLPattern has been replaced by
  django.urls.resolvers.URLPattern; affects OpenAPI code and related
  features which re-parse Django's internals.
  https://code.djangoproject.com/ticket/28593
* test_runner: Change number to suffix. Django changed the name in this
  ticket: https://code.djangoproject.com/ticket/28578
* Delete now-unnecessary SameSite cookie code (it's now the default).
* forms: urlsafe_base64_encode returns string in Django 2.2.
  https://docs.djangoproject.com/en/2.2/ref/utils/#django.utils.http.urlsafe_base64_encode
* upload: Django's File.size property replaces _get_size().
  https://docs.djangoproject.com/en/2.2/_modules/django/core/files/base/
* process_queue: Migrate to new autoreload API.
* test_messages: Add an extra query caused by .refresh_from_db() losing
  the .select_related() on the Realm object.
* session: Sync SessionHostDomainMiddleware with Django 2.2.

There's a lot more we can do to take advantage of the new release;
this is tracked in #11341.

Many changes by Tim Abbott, Umair Waheed, and Mateusz Mandera squashed
are squashed into this commit.

Fixes #10835.

Mateusz Mandera 7c78d8a966 rate_limiter: Limit the amount of password reset emails to one address.
This limits the possibility to use the password reset form to make us
spam an email address with password reset emails.
2020-02-02 19:15:13 -08:00
Mateusz Mandera 06198af5b9 auth: Handle rate limiting in OurAuthenticationForm and user_settings.
These parts of the code should catch the RateLimited exception and
generate their own, apprioprate user-facing error message.
2020-02-02 19:15:13 -08:00
Mateusz Mandera 677764d9ca auth: Pass request kwarg in authenticate() calls with username+password.
These authenticate() calls use either Email or LDAP backends, which will
be rate limited and will need access to the request object.
2020-02-02 19:15:00 -08:00
Mateusz Mandera 06c2161f7e auth: Use zxcvbn to ensure password strength on server side.
For a long time, we've been only doing the zxcvbn password strength
checks on the browser, which is helpful, but means users could through
hackery (or a bug in the frontend validation code) manage to set a
too-weak password.  We fix this by running our password strength
validation on the backend as well, using python-zxcvbn.

In theory, a bug in python-zxcvbn could result in it producing a
different opinion than the frontend version; if so, it'd be a pretty
bad bug in the library, and hopefully we'd hear about it from users,
report upstream, and get it fixed that way. Alternatively, we can
switch to shelling out to node like we do for KaTeX.

Fixes #6880.

Anders Kaseorg becef760bf cleanup: Delete leading newlines.
Previous cleanups (mostly the removals of Python __future__ imports)
were done in a way that introduced leading newlines.  Delete leading
newlines from all files, except static/assets/zulip-emoji/NOTICE,
which is a verbatim copy of the Apache 2.0 license.

Rishi Gupta d84238ce74 ktlo: Contact org admin instead of server admin for wrong subdomain error. (#12543)
Did a quick pass through the codebase; I think this is the only place we
suggest contacting server admin instead of org admin for an issue like this.

Anders Kaseorg 9efda71a4b get_realm: raise DoesNotExist instead of returning None.
This makes the implementation of `get_realm` consistent with its
declared return type of `Realm` rather than `Optional[Realm]`.

Rishi Gupta 0844c9a6ec emails: Update text for password_reset.
Note that a pretty common use case for this is a realm admin sending this to
everyone after an import from HipChat or Slack. So this adds the realm_name
to the title (so that there is something they might recognize) and kept the
wording generic enough to accommodate the user not having clicked anything
to get this email.

Also strengthens the tests a bit to better test the complicated template
logic.

Tim Abbott b2fc017671 i18n: Use the recipient's language when sending outgoing emails.
It appears that our i18n logic was only using the recipient's language
for logged-in emails, so even properly tagged for translation and
translated emails for functions like "Find my team" and "password
reset" were being always sent in English.

With great work by Vishnu Ks on the tests and the to_emails code path.

Tim Abbott e603237010 email: Convert accounts code to use delivery_email.
A key part of this is the new helper, get_user_by_delivery_email.  Its
verbose name is important for clarity; it should help avoid blind
copy-pasting of get_user (which we'll also want to rename).
Unfortunately, it requires detailed understanding of the context to
figure out which one to use; each is used in about half of call sites.

Another important note is that this PR doesn't migrate get_user calls
in the tests except where not doing so would cause the tests to fail.
This probably deserves a follow-up refactor to avoid bugs here.

Raymond Akornor 92dc3637df send_email: Add support for multiple recipients.
This adds a function that sends provided email to all administrators
of a realm, but in a single email. As a result, send_email now takes
arguments to_user_ids and to_emails instead of to_user_id and
to_email.

We adjust other APIs to match, but note that send_future_email does
not yet support the multiple recipients model for good reasons.

Tweaked by tabbott to modify `manage.py deliver_email` to handle
backwards-compatibily for any ScheduledEmail objects already in the
database.

Tim Abbott 3842404cc0 ldap: Don't allow password reset for users in LDAP domain.
This is the analog of the last commit, for the password reset flow.
For these users, they should be managing/changing their password in
the LDAP server.

The error message for users doing the wrong thing here is nonexistent
isn't great, but it should be a rare situation.

Tim Abbott 336ad0fbb1 password reset: Handle deactivated users and realms.
Since this is a logged-out view, need to actually write code for the
case of deactivated realms.

The change to get_active_user is more for clarity; the Django password
reset form already checks for whether the user is active earlier.
