Mateusz Mandera 2d55c7e0d5 home: Don't assume user agent header is set for insecure_desktop_app.
The header may not be set - this leads to CI failures on 2.1.x branch,
but in any case is a real bug.

Tim Abbott d79a7a8c35 panels: Show a banner for users with legacy desktop apps.
Users who are using ZulipDesktop or haven't managed to auto-update to
ZulipElectron should be strongly encouraged to upgrade.

We'll likely want to move to something even stricter that blocks
loading the app at all, but this is a good start.

Mateusz Mandera f2903e9c70 auth: Refactor - convert remote_username to email in remote_user_sso.
So far the conversion was in a very random place -
register_remote_user(). All other codepaths that use
login_or_register_remote_user() call it with the user's email address.
Making remote_user_sso convert remote_username to the email address
before calling login_or_register_remote_user makes this usage consistent
across the board.

Mateusz Mandera 98ae2fb940 auth: Remove redundant realm argument to finish_desktop_flow.
finish_desktop_flow is called with the assumption that the request
successfully proved control over the user_profile and generates a
special link to log into the user_profile account. There's no reason to
pass the realm param, as user_profile.realm can be assumed.

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* urls: django.urls.resolvers.RegexURLPattern has been replaced by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.

Steve Howell 1b6578cafd messages: Fix bug with commas in stream names.
We now validate streams with a separate
function from PM recipients.

It's confusing enough all the ways you can
encode a stream or encode the PM recipients,
but trying to do it all in one function was
hard to reason about and led to at least one
bug.

In particular, there was a bug where streams
with commas in them would get split.  Now
we just don't ever split on commas inside
of `extract_stream_indicator`.

Steve Howell a5093be867 presence: Rename get_status_list.
The word "status" is vague, and this isn't
actually returning a list, so we now name it
get_presence_response.

I originally was gonna rename this to
get_presence_dict, but there's a function
called get_status_dict that returns a subset
of the response, so I think it's a bit more
clear that this is the bigger dict that
actually gets sent back.

Steve Howell 8a1fb2dcd6 presence: Calculate server_timestamp slightly earlier.
We want to err on the side of server_timestamp being
old, since we may eventually use this to make responses
just include incremental changes, and we don't want a
time window (however small) when we miss presence rows.
The clients will be able to deal with duplicate data
to the extent that the time windows are overlapping.

Also, extracting the other local var here
(for `presences`) will set up a subsequent commit
where we re-format the data for clients with
slim_presence=True.

Ryan Rehman 174b2abcfd settings: Migrate to stream_post_policy structure.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.

It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.

This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.

Ray Kraesig d7b900ca52 register: Ensure future client_capabilities fields are optional.
The `notification_settings_null` field of the `client_capabilities`
parameter is, apparently unintentionally, required.

This is mostly harmless. However, if any _future_ fields are made
required, all existing clients using this parameter will break, and it
will be needlessly difficult for new clients to specify new
capabilities in a backwards-compatible way.

Attempt to stave that possibility off with warnings.

(No functional changes.)

Tim Abbott b25fea24e7 messages: Simplify API for use_first_unread_anchor.
Now that we have the type situation of having anchor support passing a
string, this is a much more natural way to implement
use_first_unread_anchor.

We still support the old interface to avoid breaking compatibility
with legacy versions of the mobile apps.

Tim Abbott 05108760f6 narrow: Add support for passing oldest/newest for anchor.
A wart that has long been present inin Zulip's get_messages API is how
to request "the latest messages" in the API.  Previously, the
recommendation was basically to pass anchor=10000000000000000 (for an
appropriately huge number). An accident of the server's implementation
meant that specific number of 0s was actually important to avoid a
buggy (or at least wasteful) value of found_newest=False if the query
had specified num_after=0 (since we didn't check).

This was the cause of the mobile issue
https://github.com/zulip/zulip-mobile/issues/3654.

The solution is to allow passing a special value of anchor='newest',
basically a special string-type value that the server can interpret as
meaning the user precisely just wants the most recent messages.  We
also add an analogous anchor='oldest' or similar to avoid folks
needing to write a somewhat ugly anchor=0 for fetching the very first
messages.

We may want to also replace the use_first_unread_anchor argument to be
a "first_unread" value for the anchor parameter.

While it's not always ideal to make a value have a variable type like
this, in this case it seems like a really clean way to express the
idea of what the user is asking for in the API.

Tim Abbott e2810d7549 narrow: Fix server handling of other larger anchor values.
This fixes a bug where that clients using the legacy approach of a
"very large anchor" value with the intent to only get the most recent
messages would only get found_newest=True if they used the specific
value LARGER_THAN_MAX_MESSAGE_ID.  Now any value at least that large
will work.

In upcoming commits, we plan to replace this with passing the string
"last", but it seems worth removing the buggy "special value" behavior
while we're touching this code.

Tim Abbott a3f08f01ec django: Use request.user.is_authenticated consistently.
In Django 2.0, request.user.is_authenticated stops supporting
`.is_authenticated()` and becomes just a property.  In 1.11, it's a
CallableProperty (i.e. can be used either way), and we already use it
as a property in several other places, so we should just switch to
using it consistently now to get it off of our Django 2.x migration
checklist.

Mateusz Mandera 8d987ba5ae auth: Use tokens, with data stored in redis, for log_into_subdomain.
The desktop otp flow (to be added in next commits) will want to generate
one-time tokens for the app that will allow it to obtain an
authenticated session. log_into_subdomain will be the endpoint to pass
the one-time token to. Currently it uses signed data as its input
"tokens", which is not compatible with the otp flow, which requires
simpler (and fixed-length) token. Thus the correct scheme to use is to
store the authenticated data in redis and return a token tied to the
data, which should be passed to the log_into_subdomain endpoint.

In this commit, we replace the "pass signed data around" scheme with the
redis scheme, because there's no point having both.

Anders Kaseorg ea6934c26d dependencies: Remove WebSockets system for sending messages.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013.  We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not.  Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.

While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.

This WebSockets code path had a lot of downsides/complexity,
including:

* The messy hack involving constructing an emulated request object to
  hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
  needs and must be provisioned independently from the rest of the
  server).
* A duplicate check_send_receive_time Nagios test specific to
  WebSockets.
* The requirement for users to have their firewalls/NATs allow
  WebSocket connections, and a setting to disable them for networks
  where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
  been poorly maintained, and periodically throws random JavaScript
  exceptions in our production environments without a deep enough
  traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
  server restart, and especially for large installations like
  zulipchat.com, resulting in extra delay before messages can be sent
  again.

As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients.  We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.

If we later want WebSockets, we’ll likely want to just use Django
Channels.

Nat1405 d5f005fd61 wildcard_mentions_notify: Add per-stream override of global setting.
Adds required API and front-end changes to modify and read the
wildcard_mentions_notify field in the Subscription model.

It includes front-end code to add the setting to the user's "manage
streams" page. This setting will be greyed out when a stream is muted.
The PR also includes back-end code to add the setting the initial state of
a subscription.

New automated tests were added for the API, events system and front-end.
In manual testing, we checked that modifying the setting in the front end
persisted the change in the Subscription model. We noticed the notifications
were not behaving exactly as expected in manual testing; see
https://github.com/zulip/zulip/issues/13073#issuecomment-560263081 .

Mateusz Mandera fcc91ae370 ldap: Disallow creating non-ldap accounts matching LDAP_APPEND_DOMAIN.
In configurations with LDAP_APPEND_DOMAIN, we don't want people creating
non-ldap accounts with emails matching the ldap domain.
So in the registration flow, if the email isn't found in LDAP, but
matches LDAP_APPEND_DOMAIN, we stop, rather than proceeding with account
creation. In case of emails not matching LDAP_APPEND_DOMAIN, we will
still continue to make a normal, non-ldap account.

Mateusz Mandera 82674b9b83 register: Improve handling of non-ldap users in LDAPPopulator configs.
The problem was that, for example, given a configuration of social
backend + LDAPPopulator, if a user that's not in ldap was being
registered, the Full Name field in the registration form would be
empty instead of getting prefilled with the name provided by the
social backend.

This fixes it - first we try to get the name from ldap. If that
succeeds, a form is created pre-filled with that name.  Otherwise, we
proceed to attempt to pre-fill with other means.

This also has a nice side effect of reorganizing most of the logic to
be more parallel between LDAP and other sources of name data.

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.

Mateusz Mandera 8c065d1fcd ldap: Ensure django_to_ldap_username returns username that is in ldap.
This changes the way django_to_ldap_username works to make sure the ldap
username it returns actually has a corresponding ldap entry and raise an
exception if that's not possible. It seems to be a more sound approach
than just having it return its best guess - which was the case so far.
Now there is a guarantee that what it returns is the username of an
actual ldap user.

This allows communicating to the registration flow when the email being
registered doesn't belong to ldap, which then will proceed to register
it via the normal email backend flow - finally fixing the bug where you
couldn't register a non-ldap email even with the email backend enabled.

These changes to the behavior of django_to_ldap_username require small
refactorings in a couple of other functions that call it, as well as
adapting some tests to these changes. Finally, additional tests are
added for the above-mentioned registration flow behavior and some
related corner-cases.

Tim Abbott d364891894 ldap: Fix password prompt when configured only to populate data.
Previously, the logic for determining whether to provide an LDAP
password prompt on the registration page was incorrectly including it
if any LDAP authentication was backend enabled, even if LDAP was
configured with the populate-only backend that is not responsible for
authentication (just for filling in name and custom profile fields).

We fix this by correcting the conditional, and add a test.

There's still follow-up work to do here: We may still end up
presenting a registration form in situations where it's useless
because we got all the data from SAML + LDAP.  But that's for a future
issue.

Mateusz Mandera d70e1bcdb7 settings: Add FAKE_EMAIL_DOMAIN setting.
Fixes #9401.

This adds a FAKE_EMAIL_DOMAIN setting, which should be used if
EXTERNAL_HOST is not a valid domain, and something else is needed to
form bot and dummy user emails (if email visibility is turned off).
It defaults to EXTERNAL_HOST.

get_fake_email_domain() should be used to get this value. It validates
that it's correctly set - that it can be used to form valid emails.

If it's not set correctly, an exception is raised. This is the right
approach, because it's undesirable to have the server seemingly
peacefully operating with that setting misconfigured, as that could
mask some hidden sneaky bugs due to UserProfiles with invalid emails,
which would blow up the moment some code that does validate the emails
is called.

We fix this by excluding the path type parameters in both places from

I doubt this is the correct long-term fix; in particular, I don't
think we're actually running the validators for these path-only

Priyank Patel 0307b6d684 refactor: Make get_stream_name_from_narrow return stream.
This function was used only once in exclude_muting_conditions where
it returned stream name so the function to fetch stream id.
Since we exepect the narrow to also include stream id we refactor it to
return a stream object and since we use get_stream_by_narrow_operand_access_unchecked
we don't need to worry about handling cases where stream id is passed since
the function handles it.

it should be used with caution.

meiomorphism 1af72a2745 subscriptions: Avoid sending unneeded subscriber information.
The `users/me/subscriptions` endpoint accidentally started returning
subscriber information for each stream.  This is convenient, but
unnecessarily costly for those clients which either don't need it
(most API apps) or already acquire this information via /register
(including Zulip's apps).

This change removes that data set from the default response.  Clients
which had come to rely on it, or would like to rely on it in future,
may still access it via an additional documented API parameter.

Fixes #12917.

Anders Kaseorg 13a2ac7b8e request: Remove ExtractRecipients type safety hole on REQ.

(and are) called with a list of `int` as `notification_to`, not just a
list of `str`.

The problem it was working around already had a better solution using
the dummy `type` argument.  Use that.

Rishi Gupta 8167b5b645 email: Remove special integration doc behavior when gateway not set.
The current code looks like it's trying to redirect /integrations/doc/email
to /integrations when EMAIL_GATEWAY_PATTERN is not set.

I think it doesn't currently do this. The test for that pathway has a bug:
self.get_doc('integrations/doc-html/email', subdomain='zulip') needs a
leading slash, and putting the slash back in results in the test failing.

This redirection is not really desired behavior -- better is to
unconditionally show that the email integration exists, and just point the
user to https://zulip.readthedocs.io/en/latest/production/email-gateway.html
(this is done in a child commit).

Hemanth V. Alluri ede73ee4cd streams: New stream messages should be auto marked as read by creator.
When a person creates a new realm, they'll likely want to create a
bunch of initial streams at once. When doing so, it could be annoying
to have to mark all of the new stream notification messages as read.

Thus to make this process smoother, we should automatically mark
the messages generated by the Notification Bot in the notifications
(announcements) stream, as well as in the newly created stream itself
as read by the stream creator.

* GoogleMobileOauth2Backend, the ancient code path for mobile
  authentication last used by the EOL original Zulip Android app.

* The `finish_google_oauth2` code path in zerver/views/auth.py, which
  was the webapp (and modern mobile app) Google authentication code
  path.

This change doesn't fix any known bugs; its main benefit is that we
get to remove hundreds of lines of security-sensitive semi-duplicated

happening was that the view functions weren't imported and hence
the arguments map was not filled. Thus the test complained that

missing in the code. Also, for the events register endpoint, we
have renamed one of the documented request parameters from
"stream" to "topic" (the API itself was not modified though).

that confirmation links were taking the user to the /register form on
the Apache server, which of course doesn't work because the Apache
server architecture we have is intended to only serve a single
endpoint, /accounts/login/sso, and not any static assets (etc.).

This manifested as users getting a broke page with a bunch of JS
errors about missing static assets when trying to sign up for an
account.  The right fix is to ensure that we serve these confirmation
links (and maybe in the future, redirects) to the nginx server.

Roman Godov a50824e031 models: Rename Subscription.in_home_view field to is_muted.
This renames Subscription.in_home_view field to is_muted, for greater
clarity as to what it does just from seeing the setting name, without
having to look it up.

Also disabled an obsolete test_migrations test.

Fixes #10042.

Harshit Bansal b553507412 subscriptions: Migrate notification setting defaults model.
This commit migrates the Subscription's notification fields from a
BooleanField to a NullBooleanField where a value of None means to
inherit the value from user's profile.

Also includes a migrations to set the corresponding settings to None
if they match the user profile's values. This migration helps us in
getting rid of the weird "Apply to all" widget that we offered on
subscription settings page.

The mobile apps can't handle None appearing as the stream-level
notification settings, so for backwards-compatibility we arrange to
only send True/False to the mobile apps by applying those defaults
server-side.  We introduce a notification_settings_null value within a
client_capabilities structure that newer versions of the mobile apps
can use to request the new model.

This mobile compatibility code is pretty effectively tested by the
existing test_events tests for the subscriptions subsystem.

vinitS101 18a424be79 uploads: Remove unusable UI elements if file uploading is disabled.
If MAX_FILE_UPLOAD_SIZE is set to 0, then UI elements like the upload

A different error message is also displayed if a user tries to drag and
drop or paste a file into the compose message box.

David Wood 34d810aac3 settings: Migrate to create_stream_policy structure.
This commit replaces the `create_stream_by_admins_only` setting with a
new `create_stream_policy` setting, which mirroring the structure of
the existing `invite_to_stream_policy`.

This is important preparation for migrating the waiting period feature
to be its own independent setting.

Shubham Padia 4994a6c2c9 realm: Add setting to disable avatar changes.
This is useful when syncing avatars from an integrated LDAP/active
directory.

The upload avatar and delete avatar buttons are hidden if avatar
changes are disabled and the user is a non-admin.
If the user has a gravatar set, then the user will not be able to
upload an image as their avatar if avatar changes are disabled.

neiljp (Neil Pilgrim) 47de637c3d mirrors: Refactor create_mirrored_message_users to use new Exception.
This enables the function to either return a valid UserProfile or raise
InvalidMirrorInput, which is clearer and more pythonic than the previous
approach of a tuple of a bool and Optional[UserProfile].

In making the type clearer, this improves checking with mypy.

Tests updated.

David Wood 272ed90685 settings: Create an explicit invite_to_stream_policy setting.
This commit creates a new organization setting that determines whether
a user can invite other users to streams. Previously this was linked
to the waiting period threshold, but this was both not documented and
overly limiting.

With significant tweaks by tabbott to change the database model to not
involve two threshhold fields, edit the tests, etc.

This requires follow-up work to make the create stream policy setting
work how this code implies it should.

Fixes #12042.

Wyatt Hoodes d4715f23d7 public_export: Add backend API endpoint for triggering export.
An endpoint was created in zerver/views.  Basic rate-limiting was
implemented using RealmAuditLog.  The idea here is to simply log each
export event as a realm_exported event.  The number of events
occurring in the time delta is checked to ensure that the weekly
limit is not exceeded.

The event is published to the 'deferred_work' queue processor to
prevent the export process from being killed after 60s.

Upon completion of the export the realm admin(s) are notified.
