Tim Abbott e7cf1112c8 notifications: Enable online push notifications by default.
For new user onboarding, it's important for it to be easy to verify
that Zulip's mobile push notifications work without jumping through
hoops or potentially making mistakes.  For that reason, it makes sense
to toggle the notification defaults for new users to the more
aggressive mode (ignoring whether the user is currently actively
online); they can set the more subtle mode if they find that the
notifications are annoying.

Mateusz Mandera 9a42a83e15 streams: Remove get_stream_recipients function and its uses.
With the recipient field being denormalized into the UserProfile and
Streams models, all current uses of get_stream_recipients can be done
more efficiently, by simply checking the .recipient_id attribute on the
appropriate objects.

Mateusz Mandera 9995dab095 messages: Save a database query in check_message code path.
The flow in recipient_for_user_profiles previously worked by doing
validation on UserProfile objects (returning a list of IDs), and then
using that data to look up the appropriate Recipient objects.

For the case of sending a private message to another user, the new
UserProfile.recipient column lets us avoid the query to the Recipient
table if we move the step of reducing down to user IDs to only occur
in the Huddle code path.

Tim Abbott 299896b6ce notifications: Ignore mobile presence when sending notifications.
Previously, if the user had interacted with the Zulip mobile app in
the last ~140 seconds, it's likely the mobile app had sent presence
data to the Zulip server, which in turns means that the Zulip server
might not send that user mobile push notifications (or email
notifications) about new messages for the next few minutes.

The email notifications behavior is potentially desirable, but the
push notifications behavior is definitely not -- a private message
reply to something you sent 2 minutes ago is definitely something you
want a push notification for.

This commit partially addresses that issue, by ignoring presence data
from the ZulipMobile client when determining whether the user is
currently engaging with a Zulip client (essentially, we're only
considering desktop activity as something that predicts the user is
likely to see a desktop notification or is otherwise "online").

Tim Abbott 958f39a551 message_edit: Call check_attachment_reference_change unconditionally.
This removes the last of the messy use of regular expressions outside
bugdown to make decisions on whether a message contains an attachment
or not.  Centralizing questions about links to be decided entirely
within bugdown (rather than doing ad-hoc secondary parsing elsewhere)
makes the system cleaner and more robust.

Rohitt Vashishtha 3fbb050216 messages: Remove dependence on regex for claiming attachments.
This commit wraps up the work to remove basic regex based parsing
of messages to handle attachment claiming/unclaiming. We now use
the more dependable Bugdown processor to find potential links and
only operate upon those links instead of parsing the full message
content again.

Rohitt Vashishtha 3892a8afd8 messages: Set has_attachment correctly using Bugdown.
Previously, we would naively set has_attachment just by searching
the whole messages for strings like `/user_uploads/...`. We now
prevent running do_claim_attachments for messages that obviously
do not have an attachment in them that we previously ran.

For example: attachments in codeblocks or
             attachments that otherwise do not match our link syntax.

The new implementation runs that check on only the urls that
bugdown determines should be rendered. We also refactor some
Attachment tests in test_messages to test this change.

The new method is:

1. Create a list of potential_attachment_urls in Bugdown while rendering.
2. Loop over this list in do_claim_attachments for the actual claiming.
   For saving:
3. If we claimed an attachment, set message.has_attachment to True.
   For updating:
3. If claimed_attachment != message.has_attachment: update has_attachment.

We do not modify the logic for 'unclaiming' attachments when editing.

Mateusz Mandera 6dbd2b5fc3 auth: Merge RemoteUserBackend into external_authentication_methods.
We register ZulipRemoteUserBackend as an external_authentication_method
to make it show up in the corresponding field in the /server_settings
endpoint.

This also allows rendering its login button together with
Google/Github/etc. leading to us being able to get rid of some of the
code that was handling it as a special case - the js code for plumbing
the "next" value and the special {% if only_sso %} block in login.html.
An additional consequence of the login.html change is that now the
backend will have it button rendered even if it isn't the only backend
enabled on the server.
2019-12-10 20:16:21 +01:00
Mateusz Mandera a842968090 auth: Expand on the external_auth_method abstraction.
This commit builds a more complete concept of an "external
authentication method". Our social backends become a special case of an
external authentication method - but these changes don't change the
actual behavior of social backends, they allow having other backends
(that come from python-social-auth and don't use the social backend
pipeline) share useful code that so far only serviced social backends.
Most importantly, this allows having other backends show up in the
external_authentication_methods field of the /server_settings endpoint,
as well as rendering buttons through the same mechanism as we already
did for social backends.

This moves the creation of dictonaries describing the backend for the
API and button rendering code away into a method, that each backend in
this category is responsible for defining.

To register a backend as an external_authentication_method, it should
subclass ExternalAuthMethod and define its dict_representation
classmethod, and finally use the external_auth_method class decorator to
get added to the EXTERNAL_AUTH_METHODS list.

Rohitt Vashishtha 1229e69e9b bugdown: Reenable -,+ to begin a markdown list.
This commit has a side-effect that we also now allow mixed lists,
but they have different syntax from the commonmark implementation
and our marked output. For example, without the closing li tags:

  Input    Bugdown     Marked
-------------------------------------
         <ul>
- Hello    <li>Hello  <ul><li>Hello</ul>
+ World    <li>World  <ul><li>World
+ Again    <li>Again      <li>Again</ul>
* And      <li>And    <ul><li>And
* Again    <li>Again      <li>Again</ul>
         </ul>

The bugdown render is in line with what a user in #13447 requests.

Fixes #13477.

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 .

Tweaked by tabbott to fix real-time synchronization issues.

Mateusz Mandera dda3ff41e1 messages: Optimize get_recent_private_conversations.
Previously, get_recent_private_messages could take 100ms-1s to run,
contributing a substantial portion of the total runtime of `/`.

We fix this by taking advantage of the recent denormalization of
personal_recipient into the UserProfile model, allowing us to avoid
the complex join with Recipient that was previously required.

The change that requires additional commentary is the change to the
main, big SQL query:
1. We eliminate UserMessage table from the query, because the condition
m.recipient_id=%(my_recipient_id)d
implies m is a personal message to the user being processed - so joining
with usermessage to check for user_profile_id and flags&2048 (which
checks the message is private) is redundant.
2. We only need to join the Message table with UserProfile
(on sender_id) and get the sender's personal_recipient_id from their
UserProfile row.

Fixes #13437.

Mateusz Mandera 8acfa17fe6 models: Add recipient foreign key in UserProfile and Stream.
This is adds foreign keys to the corresponding Recipient object in the
UserProfile on Stream tables, a denormalization intended to improve
performance as this is a common query.

In the migration for setting the field correctly for existing users,
we do a direct SQL query (because Django 1.11 doesn't provide any good
method for doing it properly in bulk using the ORM.).

A consequence of this change to the model is that a bit of code needs
to be added to the functions responsible for creating new users (to
set the field after the Recipient object gets created).  Fortunately,
there's only a few code paths for doing that.

Also an adjustment is needed in the import system - this introduces a
circular relation between Recipient and UserProfile. The field cannot be
set until the Recipient objects have been created, but UserProfiles need
to be created before their corresponding Recipients. We deal with this
by first importing UserProfiles same way as before, but we leave the
personal_recipient field uninitialized. After creating the Recipient
objects, we call a function to set the field for all the imported users
in bulk.

A similar change is made for managing Stream objects.

Mateusz Mandera 586a5facc9 models: Add is_realm_admin and is_guest setters.
Fixes #13452.

The migration from UserProfile.is_realm_admin/UserProfile.is_guest in
e10361a832 broke our LDAP-based support
for setting a user's role via LDAP properties, which relied on setting
those fields.  Because the django-auth-ldap feature powering that only
supports booleans (and in any case, we don't want to expose constants
like `ROLE_REALM_ADMINISTRATOR` to the LDAP configuration interface),
it makes sense to provide setters for these legacy fields for
backwards-compatibility.

We lint against using these setters directly in Zulip's codebase
directly.  The issue with using these is that when changing user's
.role we want to create appropriate RealmAuditLog entries and send
events. This isn't possible when using these setters - the log entries
and events should be created if the role change in the UserProfile is
actually save()-ed to the database - and on the level of the setter
function, it's not known whether the change will indeed be saved.

It would have to be somehow figured out on the level of post_save
signal handlers, but it doesn't seem like a good design to have such
complexity there, for the sake of setters that generally shouldn't be
used anyway - because we prefer the do_change_is_* functions.

The purpose of this change is narrowly to handle use cases like the
setattr on these boolean properties.

Vishnu KS c8ede33fc3 openapi: Specify securityScheme for the API in root level.
We used to specify the securityScheme for each REST operation seperately.
This is unecessary as the securityScheme can be specified in root level
and would be automatically applied to all operations. This also prevents
us accidentally not specifying the securityScheme for some operations and
was the case for /users/me/subscriptions PATCH endpoint. The root level
securityScheme can be also overriden in the operational level when
necessary.

Mateusz Mandera 7d0444f903 push_notifs: Improve handling of errors when talking to the bouncer.
We use the plumbing introduced in a previous commit, to now raise
PushNotificationBouncerRetryLaterError in send_to_push_bouncer in case
of issues with talking to the bouncer server. That's a better way of
dealing with the errors than the previous approach of returning a
"failed" boolean, which generally wasn't checked in the code anyway and
did nothing.
The PushNotificationBouncerRetryLaterError exception will be nicely
handled by queue processors to retry sending again, and due to being a
JsonableError, it will also communicate the error to API users.
2019-12-04 09:58:22 -08:00
Mateusz Mandera 20b30e1503 push_notifs: Set up plumbing for retrying in case of bouncer error.
We add PushNotificationBouncerRetryLaterError as an exception to signal
an error occurred when trying to communicate with the bouncer and it
should be retried. We use JsonableError as the base class, because this
signal will need to work in two roles:
1. When the push notification was being issued by the queue worker
PushNotificationsWorker, it will signal to the worker to requeue the
event and try again later.
2. The exception will also possibly be raised (this will be added in the
next commit) on codepaths coming from a request to an API endpoint (for
example to add a token, to users/me/apns_device_token). In that case,
it'll be needed to provide a good error to the API user - and basing
this exception on JsonableError will allow that.

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.
2019-12-02 17:44:11 -08:00
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.
