Tim Abbott b7b173d2ae realm: Fix type-checking for message_retention_days.
The best way to handle this is to have the potentially string-typed
value be a separate variable.

Tim Abbott 4fff858aa2 templates: Fix missing quoting of attributes in HTML templates.
This fixes a bundle of issues where we were missing "" around
attributes coming from variables.  In most cases, the variables were
integers or fixed constants from the Zulip codebase (E.g. the name of
an installed integration), but in at least one case it was
user-provided data that could potentially have security impact.

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.

memcached 1.5.22 in Ubuntu 20.04 has a bug where it looks for its SASL

Steve Howell 43e5b2d28b right sidebar: Remove "GROUP PMs" section.
We remove the "GROUP PMs" section that used
to be in the lower right sidebar.

Most of this is straightforward code removal.

A couple quick notes:

    - The message fetching code now just
      calls `huddle_data.process_loaded_messages`,
      which we still need for search suggestions.
      We removed `activity.process_loaded_messages`.

    - The `huddle_data.process_loaded_messages`
      function no longer needs to return `need_resize`.

    - In `resize.js` we now just calculate
      `res.buddy_list_wrapper_max_height` directly
      from `usable_height`.

Anders Kaseorg 68cfcd6446 CVE-2020-9444: Prevent reverse tabnabbing attacks.
While we could fix this issue by changing the markdown processor,
doing so is not a robust solution, because even a momentary bug in the
markdown processor could allow cached messages that do not follow our
security policy.

This change ensures that even if our markdown processor has bugs that
result in rendered content that does not properly follow our policy of
using rel="noopener noreferrer" on links, we'll still do something
reasonable.

Steve Howell 7ec5fbab2e node tests: Remove templates test.
I believe we can remove these and rely on
other parts of our testing/code-review
to ensure template quality.

These tests never really exercised our
app code, as evidenced by us not regressing
any of the 100%-line-coverage files.

We have a couple other ways that we verify
the correct format of the templates:

    - webpack (can they compile?)
    - check-templates (are they nicely indented?)

For deep testing, we have Casper, which
exercises most of our most important templates
in some meaningful way.

I think it's pretty rare that we get bugs
now that are directly caused by bad templates,
and an even smaller subset of them would
have been caught by the node tests.

If that trend changes in the future, I would prefer to
just do something "greenfield" to address
any common problems rather than resurrect
this code, but we could always resurrect it
from git.

The template node tests did check a little bit of
detail about which fields are there, but not
in an integrated way, so that aspect of the tests
wasn't very useful either.

There are two chunks of code that I touch here

sure they're worth de-duplicating, since they
use different topics and different message
content.

Steve Howell b33552997e cross realm bots: Simplify notify_new_user.
Instead of having `notify_new_user` delegate
all the heavy lifting to `send_signup_message`,
we just rename `send_signup_message` to be
`notify_new_user` and remove the one-line
wrapper.

We remove a lot of obsolete complexity:

    - `internal` was no longer ever set to True
      by real code, so we kill it off as well
      as well as killing off the internal_blurb code
      and the now-obsolete test

    - the `sender` parameter was actually an
      email, not a UserProfile, but I think
      that got past mypy due to the caller
      passing in something from settings.py

    - we were only passing in NOTIFICATION_BOT
      for the sender, so we just hard code
      that now

    - we eliminate the verbose
      `admin_realm_signup_notifications_stream`
      parameter and just hard code it to
      "signups"

    - we weren't using the optional realm
      parameter

There's also a long ugly comment in
`get_recipient_info` related to this code
that I amended for now.
We should try to take action in a subsequent
commit.

Steve Howell eeee6edf41 pm_list: Simplify redraws for Private Messages.
We now use vdom-ish techniques to track the
list items for the pm list.  When we go to update
the list, we only re-render nodes whose data
has changed, with two exceptions:

    - Obviously, the first time we do a full render.
    - If the keys for the items have changed (i.e.
      a new node has come in or the order has changed),
      we just re-render the whole list.

If the keys are the same since the last re-render, we
only re-render individual items if their data has
changed.

Most of the new code is in these two modules:

    - pm_list_dom.js
    - vdom.js

We remove all of the code in pm_list.js that is
related to updating DOM with unread counts.

For presence updates, we are now *never*
re-rendering the whole list, since presence
updates only change individual line items and
don't affect the keys.  Instead, we just update
any changed elements in place.

The main thing that makes this all work is the
`update` method in `vdom`, which is totally generic
and essentially does a few simple jobs:

    - detect if keys are different
    - just render the whole ul as needed
    - for items that change, do the appropriate
      jQuery to update the item in place

Note that this code seems to play nice with simplebar.

Also, this code continues to use templates to render
the individual list items.

FWIW this code isn't radically different than list_render,
but it's got some key differences:

    - There are fewer bells and whistles in this code.
      Some of the stuff that list_render does is overkill
      for the PM list.

    - This code detects data changes.

Note that the vdom scheme is agnostic about templates;
it simply requires the child nodes to provide a render
method.  (This is similar to list_render, which is also
technically agnostic about rendering, but which also
does use templates in most cases.)

These fixes are somewhat related to #13605, but we
haven't gotten a solid repro on that issue, and
the scrolling issues there may be orthogonal to the
redraws.  But having fewer moving parts here should
help, and we won't get the rug pulled out from under
us on every presence update.

There are two possible extensions to this that are
somewhat overlapping in nature, but can be done
one a time.

    * We can do a deeper vdom approach here that
      gets us away from templates, and just have
      nodes write to an AST.  I have this on another
      branch, but it might be overkill.

    * We can avoid some redraws by detecting where
      keys are moving up and down.  I'm not completely
      sure we need it for the PM list.

If this gets merged, we may want to try similar
things for the stream list, which also does a fairly
complicated mixture of big-hammer re-renders and
surgical updates-in-place (with custom code).

BTW we have 100% line coverage for vdom.js.

Addresses point 1 of #13533.

MissedMessageEmailAddress objects get tied to the specific that was
missed by the user. A useful benefit of that is that email message sent
to that address will handle topic changes - if the message that was
missed gets its topic changed, the email response will get posted under
the new topic, while in the old model it would get posted under the
old topic, which could potentially be confusing.

Migrating redis data to this new model is a bit tricky, so the migration
code has comments explaining some of the compromises made there, and
test_migrations.py tests handling of the various possible cases that
could arise.

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.

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.
