Aman Agrawal 9965ad2ea3 registration: Track create organization page in GA.
This will help us track if users actually clicked on the
email confirmation link while creating a new organization.

Replaced all the `reder` calls in `accounts_register` with
`TemplateResponse` to comply with `add_google_analytics`
decorator.

Aman Agrawal 37431cf0b5 urls: Provide `email` as a GET parameter.
Since we want to use `accounts/new/send_confirm` to know how many
users actually register after visiting the register page, we
added it to Google Tag Manager, but GTM tracks every user
registration separately due <email> in the URL
making it harder to track.

To solve this, we want to pass <email> as a GET parameter which
can be easily filtered inside GTM using a RegEx and all the
registrations can be tracked as one.

Mateusz Mandera 582d5b0aa3 realm_creation: Rework error pages.
The previous error page was inadequate for serving the two different
scenarios where we show errors in realm_creations, in particular
containing a misleading sentence about realm creation being disabled
(even in the case where it was actually enabled and the user simply had
an expired link).

Mateusz Mandera 2c693f3bd9 billing: Fix licenses amount check during user signup/invitation.
Our seat count calculation is different for guest user than normal users
(a number of initial guests are free, and additional marginal guests are
worth 1/5 of a seat) - so these checks we apply when a user is being
invited or signing up need to know whether it's a guest or non-guest
being added.

Zixuan James Li c9f54766c3 rate_limiter: Extract rate limit related functions.
This refactors rate limit related functions from `zerver.decorator` to
zerver.lib.rate_limiter.

We conditionally import `RemoteZulipServer`, `RequestNotes`, and
`RateLimitedRemoteZulipServer` to avoid circular dependency.

Most instances of importing these functions from `zerver.decorator` got
updated, with a few exceptions in `zerver.tests.test_decorators`, where
we do want to mock the rate limiting functions imported in
`zerver.decorator`. The same goes with the mocking example in the
"testing-with-django" documentation.

Mateusz Mandera 0e2691815e confirmation: Prevent re-use of email change links.
The .status value of EmailChangeStatus was not being looked
at anywhere to prevent re-use of email change confirmation links. This
is not a security issue, since the EmailChangeStatus object has a fixed
value for the new_email, while the confirmation link has expiry time of
1 day, which prevents any reasonable malicious scenarios.

We fix this by making get_object_from_key look at
confirmation.content_object.status - which applies
generally to all confirmations where the attached object has the .status
attribute. This is desired, because we never want to
successfully get_object_from_key an object that has already been used or
reused.
This makes the prereg_user.status check in check_prereg_key redundant so
it can be deleted.

Mateusz Mandera 39d8a81e51 registration: Tie PreregistrationUser to the original MultiUseInvite.
Fixes #21266.

We want to tie the prereg_user to the MultiUseInvite directly rather
than to the MultiUserInvite's confirmation object, because the latter is
not possible. This is because the flow is that after going through the
multiuse invite link, the PreregistrationUser is created together with a
Confirmation object, creating a confirmation link (via
create_confirmation_link) to which then the user is redirected to finish
account creation. This means that the PreregistrationUser is already
tied to a Confirmation, so that attribute is occupied.

Mateusz Mandera cd1e062878 registration: Return proper error page if a registration link is reused.
Before this, a link still couldn't be re-used because it would trip up
exception further down user creation codepaths, but that was still a
bug. check_prereg_key is supposed to correctly validate the key - and
trigger an error page being returned if a key (or for any other reason,
the attached PreregistrationUser object) is reused.

test_validate_email_not_already_in_realm needs to be adjusted, because
it was actually re-using a key.

Zixuan James Li ab1bbdda65 typing: Broaden type annotations for QuerySet compatibility.
To explain the rationale of this change, for example, there is
`get_user_activity_summary` which accepts either a `Collection[UserActivity]`,
where `QuerySet[T]` is not strictly `Sequence[T]` because its slicing behavior
is different from the `Protocol`, making `Collection` necessary.

Similarily, we should have `Iterable[T]` instead of `List[T]` so that
`QuerySet[T]` will also be an acceptable subtype, or `Sequence[T]` when we
also expect it to be indexed.

Mateusz Mandera 7b795b6338 registration: Change create_preregistration_user to take realm as arg.
create_preregistration_user is a footgun, because it takes the realm
from the request. The calling code is supposed to validate that
registration for the realm is allowed
first, but can sometimes do that on "realm" taken from something else
than the request - and later on calls create_preregistration_user, thus
leading to prereg user creation on unvalidated request.realm.

It's safer, and makes more sense, for this function to take the intended
realm as argument, instead of taking the entire request. It follows that
the same should be done for prepare_activation_url.

problem was that validation was happening in the check_prereg_key_and_redirect

Erik Tews 1ecb87ec80 auth: show _OR_ during login only when other methods are available.
There might be good reasons to have other external authentication
methods such as SAML configured, but none of them is available.

This happens, for example, when you have enabled SAML so that Zulip is
able to generate the metadata in XML format, but you haven't
configured an IdP yet. This commit makes sure that the phrase _OR_ is
only shown on the login/account page when there are actually other
authentication methods available. When they are just configured, but
not available yet, the page looks like as if no external
authentication methods are be configured.

We achieve this by deleting any_social_backend_enabled, which was very
similar to page_params.external_authentication_methods, which
correctly has one entry per configured SAML IdP.

this can even trigger a 500 error from PostgreSQL.

Stop calling `validate_email_not_already_in_realm` in the form
validation. The form is currently only used in two places -- in
`accounts_home` and in `maybe_send_to_registration`.  The latter is
only called if the address is known to not currently have an account,
so checking in there is unnecessary; and in the former case, we wish
different behaviour (the redirect) than just validation failure, which
is all the validator can do.

Steve Howell 9df9934ed6 refactor: Pass realm to bulk_add_subscriptions.
I think it's important that the callers understand
that bulk_add_subscriptions assumes all streams
are being created within a single realm, so I make
it an explicit parameter.

This may be overkill--I would also be happy if we
just included the assertions from this commit.

Tim Abbott 6be3fca037 auth: Remove short_name from LDAP API.
As best I can tell, we fetched this field and then ignored it, so
unlike the last few commits, this is more a code cleanup than a
functional change.

Steve Howell c44500175d database: Remove short_name from UserProfile.
A few major themes here:

    - We remove short_name from UserProfile
      and add the appropriate migration.

    - We remove short_name from various
      cache-related lists of fields.

    - We allow import tools to continue to
      write short_name to their export files,
      and then we simply ignore the field
      at import time.

    - We change functions like do_create_user,
      create_user_profile, etc.

    - We keep short_name in the /json/bots
      API.  (It actually gets turned into
      an email.)

    - We don't modify our LDAP code much
      here.

Anders Kaseorg 69c0959f34 python: Fix misuse of Optional types for optional parameters.
There seems to have been a confusion between two different uses of the
word “optional”:

• An optional parameter may be omitted and replaced with a default
  value.
• An Optional type has None as a possible value.

Sometimes an optional parameter has a default value of None, or None
is otherwise a meaningful value to provide, in which case it makes
sense for the optional parameter to have an Optional type.  But in
other cases, optional parameters should not have Optional type.  Fix
them.

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

Graham Bleaney 461d5b1a3e pysa: Introduce sanitizers, models, and inline marking safe.
This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.

Graham Bleaney 56345f98cb registration: Incorporate redirect URL building helper function.
This commit adds 'add_query_to_redirect_url' to one additional

'add_query_to_redirect_url' was introduced. This helper centralizes
URL manipulation for redirects, making it easier to add Pysa
sanitization in subsequent commits.

clarammdantas f0c85c5796 registration: Show error if invalid key is posted on /accounts/register.
If the key paramenter on POST isn't correct we won't be
able to find the confirmation object, which will lead to
an exception. To deal with it more gracefully, we are
catching the exception and redirecting to the
confirmation_link_expired_error page.

clarammdantas edcf4f0ea2 invitations: Revoke remaining invitations after user registers.
If a user receives more than one invite to join a
realm, after that user registers, all the remaining
invitations should be revoked, preventing them to be
listed in active invitations on admin panel.
To do this, we added a new prereg_user status,
STATUS_REVOKED.

We also added a confirmation_link_expired_error page
in case the user tries click on a revoked invitaion.
This page has a link to login page.

Mateusz Mandera f1ec02b40a auth: Add ExternalAuthResult to manage data in authentication flows.
This new type eliminates a bunch of messy code that previously
involved passing around long lists of mixed positional keyword and
arguments, instead using a consistent data object for communicating
about the state of an external authentication (constructed in
backends.py).

The result is a significantly more readable interface between
zproject/backends.py and zerver/views/auth.py, though likely more
could be done.

This has the side effect of renaming fields for internally passed
structures from name->full_name, next->redirect_to; this results in
most of the test codebase changes.

Modified by tabbott to add comments and collaboratively rewrite the
initialization logic.

We can likely further refine the remaining pieces with some testing.
