Mateusz Mandera 884ff425da cache: Remove dead code for caching recipients.
With recipient column denormalized into all three of Stream, UserProfile
and Huddle, there is no more use for this caching.

Mateusz Mandera b4ce167a88 models: Add recipient foreign key to Huddle.
This follows the already tested approach from

Mateusz Mandera 0255ca9b6a middleware: Log user.id/realm.string_id instead of _email. 2020-03-09 13:54:58 -07:00
Tim Abbott 9230213bde settings: Add EMAIL_ADDRESS_VISIBILITY_NOBODY.
This extends our email address visibility settings to deny access to
user email addresses even to organization administrators.

At the moment, they can of course change the setting (which leaves an
audit trail), but in the future only organization owners will be able
to change that setting.

While we're at this, we rewrite the settings_data.js test to cover all
the cases in a more consistent way.

Fixes #14111.

Steve Howell 1b4cac6734 models: Cache failures to find user in get_user_by_api_key.
We will cache failed lookups with None.  The
use case here is that broken API clients may
continually ask for the same wrong API key, and
we want to handle that as quickly as possible.

Steve Howell 220c2a5ff3 performance: Add get_users_by_delivery_email().
The main purpose of this new function is to allow
us to validate emails in bulk, which we don't do
yet (still setting the stage for that).

This is still a speedup, though, since in our
caller we grab only three fields now.

And other than that, we're essentially doing
the same query for the single-email case, just
outside the loop.

Steve Howell ce8f6797c7 performance: Optimize get_realm_email_validator.
We now query RealmDomain objects up front.  This
change is minor in most circumstances--it sometimes
saves a round trip to the database; other times,
it actually brings back slightly more data
(optimistically).

The big win will come in a subsequent commit,
where we avoid running these queries in a loop
for every callback.

Note that I'm not sure if we intentionally
omitted checks for emails with "+" in them
for some circumstances, but I just preserved
the behavior.

Steve Howell ddbc536739 refactor: Extract get_realm_email_validator.
This change sets us up to use the same realm
data for multiple email validations.

Steve Howell 94192395fb perf: Extract Stream.get_client_data.
This function slims down the data that we get
from the database in order to create the
streams part of our client payload.

We also fix a typo.

We also clearly distinguish between queries
and lists here.

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 d68052b68d presence: Add realm/timestamp index to UserPresence.
It adds this index:

    "zerver_userpresence_realm_id_timestamp_25f410da_idx" btree (realm_id, "timestamp")

We expect this index to provide a major performance improvement when
fetching presence data for the whole realm from the database on
servers like zulipchat.com hosting several realms.
2020-02-11 13:11:28 -08:00
Steve Howell c4e3cfebb0 presence: Add realm_id to UserPresence.
This index is intended to optimize the performance of the very
frequently run query of "what is the presence status of all users in a
realm?".

Main changes:
    - add realm_id to UserPresence
    - 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.

There's also a minor tweak to the populate_db script.

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.

With many tweaks by tabbott to documentation under /help, etc.

Fixes #13616.

Tim Abbott 51706bdc3a stream: Deduplicate lists of stream/subscriptions fields.
While the result of this change doesn't completely do what we need, it
does remove a huge amount of duplicated lists of fields.  With a bit
more similar work, we should be able to eliminate a broad category of
potential bugs involving Stream and Subscription objects being
represented inconsistently in the API.

Work towards #13787.

Ryan Rehman 17413bd390 refactor: Add is_new_member property.

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
with a hacked-up settings module.

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
so that we can use them in clear_database.

We also fix a mypy erorr in flush-memcached that matches the same
issue fixed in clear_database.

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.

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.
2020-01-07 13:03:22 -08:00
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.

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 01288ede9e recipients: Remove bulk_get_recipients function and its uses.
With the recipient field being denormalized into the UserProfile and

appropriate objects.

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 fe24f4ee65 messages: Remove update_calculated_fields method.
This infrastructure is no longer needed following reworking of how
has_link and friends work.
2019-12-11 11:03:49 -08:00
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.

Tim Abbott 0c21855af8 models: Move Recipient model before UserProfile.

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.

Rohitt Vashishtha 85c669e366 markdown: Remove redundant checks from /me.
If a message begins with /me, we do not have any cases where the

Rohitt Vashishtha 3df18c365d markdown: Bring /me python code up to date with frontend.
It appears we forgot to make identical changes to the backend

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.
