Tushar912 dfafdda9b3 api: Add REST API endpoint for looking up a user by email address.
Add new rest api endpoint GET users/{email} for looking up a user by
email, which is useful especially for corporate API applications that
might already have a user's email address.

Fixes #14302.

m-e-l-u-h-a-n 0e6343c071 users: Clarify readability issues related to access_user_by_id.
zerver/lib/users.py has a function named access_user_by_id, which is
used in /users views to fetch a user by it's id. Along with fetching
the user this function also does important validations regarding
checking of required permissions for fetching the target user.

In an attempt to solve the above problem this commit introduces
following changes:
1. Make all the parameters except user_profile, target_user_id
   to be keyword only.
2. Use for_admin parameter instead of read_only.
3. Adds a documentary note to the function describing the reason for
   changes along with recommended way to call this function in future.
4. Changes in views and tests to call this function in this changed
   format.

Changes were tested using ./tools/test-backend.

Fixes #17111.

Mateusz Mandera 160cc5120a api: Require can_create_users permission to create users via API.
Allowing any admins to create arbitrary users is not ideal because it
can lead to abuse issues.  We should require something stronger that
requires the server operator's approval and thus we add a new
can_create_users permission.

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.

Steve Howell c60f4236a9 api: Do not require short_name to create user.

An upcoming commit will eliminate it from the
database.

Steve Howell 80c057d91d REQ: Use check_dict_only in update_user_backend.
Update the REQ check for profile_data in
update_user_backend by tweaking `check_profile_data`
to use `check_dict_only`.

Here is the relevant URL:

    path('users/<int:user_id>', rest_dispatch,
         {'GET': 'zerver.views.users.get_members_backend',

It would be nice to unify the validator
for these two views, but they are different:

    update_user_backend
    update_user_custom_profile_data

It's not completely clear to me why update_user_backend
seems to support a superset of the functionality
of `update_user_custom_profile_data`, but it has
this code to allow you to remove custom profile fields:

    clean_profile_data = []
    for entry in profile_data:
        assert isinstance(entry["id"], int)
        if entry["value"] is None or not entry["value"]:
            field_id = entry["id"]
            check_remove_custom_profile_field_value(target, field_id)
        else:
            clean_profile_data.append({
                "id": entry["id"],
                "value": entry["value"],
            })

Whereas the other view is much simpler:

def update_user_custom_profile_data(
    <snip>
) -> HttpResponse:

    validate_user_custom_profile_data(user_profile.realm.id, data)
    do_update_user_custom_profile_data_if_changed(user_profile, data)
    # We need to call this explicitly otherwise constraints are not check
    return json_success()

Hashir Sarwar 5200598a31 events: Don't send avatar URLs of long term idle users.
This adds a new client_capability that clients such as the mobile apps
can use to avoid unreasonable network bandwidth consumed sending
avatar URLs in organizations with 10,000s of users.

Clients don't strictly need this data, as they can always use the
/avatar/{user_id} endpoint to fetch the avatar if desired.

This will be more efficient especially for realms with
10,000+ users because the avatar URLs would increase the
payload size significantly and cost us more bandwidth.

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.

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

sahil839 6d667dbe53 realm owner: Add ability to change realm owner status of user.
This commit adds some basic checks while adding or removing
realm owner status of a user and adds code to change owner
status of a user using update_user_backend.

This also adds restriction on removing owner status of the
last owner of realm. This restriction was previously on
revoking admin status, but as we have added a more privileged
role of realm owner, we now have this restriction on owner
instead of admin.

We need to apply that restriction both in the role change code path
and the deactivate code path.

sahil839 7de23b8b5c users: Remove short_name and client_id from get_profile_backend.
This commit removes short_name and client_id fields from the user
objects returned by get_profile_backend because neither of them
had a purpose.

* short_name hasn't been present anywhere else in the Zulip API for
  several years, and isn't set through any coherent algorithm.
* client_id was a forgotten 2013-era predecessor to the queue_id field
  returned by the register_event_queue process.

have the exact same format as other endpoints fetching a user object.

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.

Mateusz Mandera 0c2cc41d2e CVE-2019-18933: Fix insecure account creation via social authentication.
A bug in Zulip's new user signup process meant that users who
registered their account using social authentication (e.g. GitHub or
Google SSO) in an organization that also allows password
authentication could have their personal API key stolen by an
unprivileged attacker, allowing nearly full access to the user's
account.

Zulip versions between 1.7.0 and 2.0.6 were affected.

This commit fixes the original bug and also contains a database
migration to fix any users with corrupt `password` fields in the
database as a result of the bug.

Out of an abundance of caution (and to protect the users of any
installations that delay applying this commit), the migration also
resets the API keys of any users where Zulip's logs cannot prove the
user's API key was not previously stolen via this bug.  Resetting
those API keys will be inconvenient for users:

* Users of the Zulip mobile and terminal apps whose API keys are reset
  will be logged out and need to login again.
* Users using their personal API keys for any other reason will need
  to re-fetch their personal API key.

We discovered this bug internally and don't believe it was disclosed
prior to our publishing it through this commit.  Because the algorithm
for determining which users might have been affected is very
conservative, many users who were never at risk will have their API
keys reset by this migration.

To avoid this on self-hosted installations that have always used
e.g. LDAP authentication, we skip resetting API keys on installations
that don't have password authentication enabled.  System
administrators on installations that used to have email authentication
enabled, but no longer do, should temporarily enable EmailAuthBackend
before applying this migration.

The migration also records which users had their passwords or API keys
reset in the usual RealmAuditLog table.
