Clara Dantas 05bf72a75c attachments: Add is_web_public field.
This commit adds the is_web_public field in the AbstractAttachment
class. This is useful when validating user access to the attachment,
as otherwise we would have to make a query in the db to check if
that attachment was sent in a message in a web-public stream or not.

sahil839 78da9fd3ab subscription: Add role field to Subscription class.
This commit adds role field to the Subscription class. Currently,
there are two option of roles - STREAM_ADMINISTRATOR and MEMBER.

We also add a property 'is_stream_admin' for checking whether the
user is stream admin or not.

Hemanth V. Alluri 0e893b9045 models/drafts: Add a model for storing Draft messages.
Also add a Draft object-to-dictionary conversion method.
The following commits will provide an API around this
model using which our clients can sync drafts across each
other (if they so wish too). As of making this commit, we
haven't finalized exactly how our clients will use this.

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

      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 1b96af2987 cache: Fix type: ignore issues.
This was hiding an actual type error in test_cache: a mismatch between
the object ID type, which is str, and the default id_fetcher, which
returns int.

Mypy’s insufficient support for default generic arguments basically
means we can’t use them without a lot of overloading, and there are
not enough callers here to justify that.

https://github.com/python/mypy/issues/3737

We avoid this being super messy where the code calls this by adding
some less generic wrappers for generic_bulk_cached_fetch.

Pragati Agrawal 1562ec758e org settings: Use 'forever' value instead of -1 for message_retention_days.
Currently, we use -1 as the Realm.message_retention_days value to retain
message forever unless specified at stream level for a particular stream,
that is, no policy set at the realm level. But this is incoherent with what
we use for Stream.message_retention_days where -1 means

> disable retention policy for this stream unconditionally

that can be confusing from an API standpoint.

So instead of trying some hack to reset the value to NULL or using some
other value like -2 for RETAIN_MESSAGE_FOREVER and use that for API. It is
much more intuitive to use a string like 'forever' that can be mapped to
RETAIN_MESSAGE_FOREVER at the backend. And this is similar to what we use
for streams settings as well.

Mateusz Mandera 7a03e2a7fe retention: Replace Realm.message_retention_days None value with -1.

value for Realm.message_retention_days in favor of the value -1 to
represent the "don't delete messages" default policy.

Mateusz Mandera 8d2d64c100 CVE-2020-14215: Fix validation in PreregistrationUser queries.
The most import change here is the one in maybe_send_to_registration
codepath, as the insufficient validation there could lead to fetching
an expired PreregistrationUser that was invited as an administrator
admin even years ago, leading to this registration ending up in the
new user being a realm administrator.

Combined with the buggy migration in
0198_preregistrationuser_invited_as.py, this led to users incorrectly
joining as organizations administrators by accident.  But even without
that bug, this issue could have allowed a user who was invited as an
administrator but then had that invitation expire and then joined via
social authentication incorrectly join as an organization administrator.

The second change is in ConfirmationEmailWorker, where this wasn't a
security problem, but if the server was stopped for long enough, with
some invites to send out email for in the queue, then after starting it
up again, the queue worker would send out emails for invites that
had already expired.

of open redirects within Zulip code. Additionally, this commit

work. This commit also puts `mark_sanitized` to work removing known

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

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.

sahil9001 328caf1ad5 api: Simplify format of realm_emoji author data.
There's no reason to send data beyond the user `id` of the uploader,
and reason not to, as the previous model was both awkward when
`author=None` and resulted in unecessary parsing complexity for
clients.

Modified by tabbott to add the frontend changes and API documentation.

Fixes #15115.

"dropdown_options_widget".

Alex Vandiver 0288002b84 models: Comment call to python2-esque `iteritems()`.
This method is called on a `bitfield.types.BitHandler` object, not a dict; as
such, it is not a runtime failure.

This was missed in 035ed93111 and adjacent commits because it was not
`six.iteritems()` but just a bare `iteritems()` -- having been added
after 9e3c3e14f5 moved all other calls from `iteritems()` to
`six.iteritems()`.

Comment on why this is not a leftover python2-ism.

Grep finds no other remaining callsites to `iteritems` or friends:

Aside from some basic tests validating the logic, this has no effect

Pragati Agrawal bd9b74436c org settings: Enable message_retention_days in org settings UI.
Since production testing of `message_retention_days` is finished, we can
enable this feature in the organization settings page. We already had this
setting in frontend but it was bit rotten and not rendered in templates.

Here we replaced our past text-input based setting with a
dropdown-with-text-input setting approach which is more consistent with our
existing UI.

Along with frontend changes, we also incorporated a backend change to
handle making retention period forever. This change introduces a new
convertor `to_positive_or_allowed_int` which only allows positive integers
and an allowed value for settings like `message_retention_days` which can
be a positive integer or has the value `Realm.RETAIN_MESSAGE_FOREVER` when
we change the setting to retain message forever.

This change made `to_not_negative_int_or_none` redundant so removed it as
well.

Fixes: #14854

The new settings lies in the "Other notification

Tim Abbott 03fecba917 alert_words: Fix cache flushing behavior and add tests.
The post_init cache-flushing behavior in the original alert words
migration was subtly wrong; while it may have passed tests, it didn't
have the right ordering for unlikely races.

We use post_save rather than post_init hooks precisely because they
ensure that we flush the cache after we know the database has been
updated and any future reads from the database will have the latest
state.
2020-04-27 11:48:32 -07:00
Tim Abbott 8e5b0351b3 alert_words: Fix case-sensitivity of alert words.
Previously, alert words were case-insensitive in practice, by which I
mean the Markdown logic had always been case-insensitive; but the data
model was not, so you could create "duplicate" alert words with the
same words in different cases.  We fix this inconsistency by making
the database model case-insensitive.

I'd prefer to be using the Postgres `citext` extension to have
postgres take care of case-insensitive logic for us, but that requires
installing a postgres extension as root on the postgres server, which
is a pain and perhaps not worth the effort to arrange given that we
can achieve our goals with transaction when adding alert words.

We take advantage of the migrate_alert_words migration we're already
doing for all users to effect this transition.

Fixes #12563.

Abhishek-Balaji 052368bd3e alert_words: Move alert_words from UserProfile to separate model.
Previously, alert words were a JSON list of strings stored in a
TextField on user_profile.  That hacky model reflected the fact that
they were an early prototype feature.

This commit migrates from that to a separate table, 'AlertWord'.  The
new AlertWord has user_profile, word, id and realm(denormalization so
we can provide a nice index for fetching all the alert words in a
realm).

This transition requires moving the logic for flushing the Alert Words
caches to their own independent feature.

Note that this commit should not be cherry-picked without the
following commit, which fixes case-sensitivity issues with Alert Words.

Puneeth Chaganti 8f32db81a1 home: Don't use pointer to compute furthest_read_time.
When a user is reading messages only in stream or topic narrows, the pointer
can be left far behind. Using this to compute the furthest_read_time causes
the banckruptcy banner to be shown even when a user has been actively
reading messages. This commit switches to using the sent time on the last

Rohitt Vashishtha f9caf522f0 markdown: Allow setting a default language for code blocks.
This adds a new realm setting: default_code_block_language.

This PR also adds a new widget to specify a language, which
behaves somewhat differently from other widgets of the same
kind; instead of exposing methods to the whole module, we
just create a single IIFE that handles all the interactions
with the DOM for the widget.

We also move the code for remapping languages to format_code
function since we want to preserve the original language to
decide if we override it using default_code_clock_language.

Django 2.2.x is the next LTS release after Django 1.11.x; I expect

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.

* 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().

* process_queue: Migrate to new autoreload API.
* test_messages: Add an extra query caused by .refresh_from_db() losing

This index is intended to optimize the performance of the very

    - add index for realm_id
    - backfill realm_id for old rows
    - change all writes to UserPresence to include
      realm_id

The index is of this form:

    "zerver_userpresence_realm_id_5c4ef5a9" btree (realm_id)

We will create an index on (realm_id, timestamp) in a
future commit, but I think it's a bit faster if you do
the backfill before the index.

Tim Abbott 571ce2f5cb populate_db: Fix handling of memcached flushing.
Our recent fixes to using the system's configured memcached settings
broke populate_db, because its hacky clear_database helper is called

We fix this by first moving this out-of-place code from models.py into
populate_db, and then saving the settings required to access memcached

Tim Abbott 79f18138f5 realm: Add private_message_policy setting.
This experimental setting disables sending private messages in Zulip
in a crude way (i.e. users get an error when they try to send one).
It makes no effort to adjust the UI to avoid advertising the idea of
sending private messages.

Fixes #6617.

Mateusz Mandera c011d2c6d3 email_mirror: Migrate missed message addresses from redis to database.
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 9077bbfefd models: Add MissedMessageEmailAddress class.
Preparatory commit for making the email mirror use the database instead
of redis for missed message addresses.

This model will represent missed message email addresses, which
currently have their data stored in redis.
The redis data will be converted and migrated into these models and
the email mirror will start using them in the main commit.

Tim Abbott 7ccc8373e2 bugdown: Fix logic for extracting attachment path_id.
In 3892a8afd8, we restructured the
system for managing uploaded files to a much cleaner model where we
just do parsing inside bugdown.

That new model had potentially buggy handling of cases around both
relative URLs and URLS starting with `realm.host`.

We address this by further rewriting the handling of attachments to
avoid regular expressions entirely, instead relying on urllib for
parsing, and having bugdown output `path_id` values, so that there's
no need for any conversions between formats outside bugdowm.

The check_attachment_reference_change function for processing message
updates is significantly simplified in the process.

The new check on the hostname has the side effect of requiring us to
fix some previously weird/buggy test data.

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.

Tim Abbott f3c224058f models: Use unlimited .select_related() for Stream and DefaultStream.
Previously, these accesses used e.g. .select_related("realm"), which
was the only foreign key on the Stream model.  Since the intent in
these code paths is to attach the related models for efficient access,
we should just do that for all related models, including Recipient.

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 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 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.

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.
