Sahil Batra 5f950e3efd models: Add create_web_public_stream_policy setting.
This commit adds create_web_public_stream_policy
field to Realm table which controls the roles that
can create web-public streams and by default its
value is set to POLICY_OWNERS_ONLY.

Sahil Batra 855f7158ea models: Remove redundant check for POLICY_EVERYONE.
We check whether policy value is POLICY_EVERYONE in
has_permission itself so there is no need to handle
that in can_edit_topic_of_any_message.

Alex Vandiver db934be064 CVE-2021-41115: Use re2 for user-supplied linkifier patterns.
Zulip attempts to validate that the regular expressions that admins
enter for linkifiers are well-formatted, and only contain a specific
subset of regex grammar.  The process of checking these
properties (via a regex!) can cause denial-of-service via
backtracking.

Furthermore, this validation itself does not prevent the creation of
linkifiers which themselves cause denial-of-service when they are
executed.  As the validator accepts literally anything inside of a
`(?P<word>...)` block, any quadratic backtracking expression can be
hidden therein.

Switch user-provided linkifier patterns to be matched in the Markdown
processor by the `re2` library, which is guaranteed constant-time.
This somewhat limits the possible features of the regular
expression (notably, look-head and -behind, and back-references);
however, these features had never been advertised as working in the
context of linkifiers.

A migration removes any existing linkifiers which would not function
under re2, after printing them for posterity during the upgrade; they
are unlikely to be common, and are impossible to fix automatically.

The denial-of-service in the linkifier validator was discovered by
@erik-krogh and @yoff, as GHSL-2021-118.

Ganesh Pawar fa928d5cd1 streams: Split setting for stream creation policy.
Users wanted a feature where they could specify
which users can create public streams and which users can
create private streams.

This splits stream creation code into two parts,
public and private stream creation.

Fixes #17009.

sahil839 9dd69c17ee settings: Add moderators and members option in delete_own_message_policy.
This commit adds moderators, full members and members options to
delete_own_message_policy in backend.

sahil839 909a3cde76 realm: Replace allow_message_deleting with delete_own_message_policy.
This commit replaces 'allow_message_deleting' boolean setting
with an integer setting 'delete_own_message_policy'. We have a
separate dropdown now for deciding which user-roles can delete
messages sent by themselves and the time-limit setting droddown
is different.

This new setting has two options - everyone and admins only. Other
options including moderators will be added further.

We also remove the "Never" option from the original time-limit
dropdown, as admins are always allowed to delete message. This
never option resembled the case of only admins being allowed to
delete but this state is now resembled by setting the dropdown
to "admins only" and we also disable the time-limit dropdown in
this case as admins are allowed to delete irrespective of limit.

Note, this setting is only for deleting messages sent by the
deleting user themselves, and only admins are allowed to delete
messages sent by others as before.

sahil839 b13bfa09c5 message: Make zero invalid value for message_content_delete_limit_seconds.
We make zero invalid value for message_content_delete_limit_seconds and
for handling the case of "Allow to delete message any time", the API-level
value of message_content_delete_limit_seconds is "anytime" and "None"
as the DB-level value. We also use these values for message retention
setting, so it helps maintain consistency.

Tim Abbott e556481ba0 streams: Remove duplicates of get_web_public_streams_queryset.
This is a somewhat subtle function, that deserves a few comments
explaining subtle details of its logic, and there's no good reason to
have multiple copies of that logic that are slightly inconsistent.

Because the main changes here are just checking for invariant
failures, the behavioral change here should be limited to ensuring
deactivated streams are not considered available even if they were
tagged as web public streams before deactivation.

Sahil Batra c233ee9935 settings: Migrate twenty_four_hour_time setting to RealmUserDefault.
This commit removes the existing default_twenty_four_hour_time field in

new user on joining and instead we now use the twenty_four_hour_time
field of RealmUserDefault table for the same.

With some tweaks by tabbott to clarify the documentation.

Mateusz Mandera 491f763f4e models: Improve conversion of CustomProfileField values.
These values are currently either a string already or a List[int]. We
should do the conversion in
do_update_user_custom_profile_data_if_changed properly: if the value is
already a string, it can be used directly - if it's not, orjson.dumps is
a more future-proof way of converting than str(). Using orjson.dumps
here also allows us to change the converter of the USER type
CustomProfileField to orjson.loads, which is nicer to have than
ast.literal_eval.
While orjson.dumps() and str() give the same output when
given the special case of List[int],
ast.literal_eval was previously used due to orjson.loads not being
a good inverse function to str in general. That gets straightened out
now.

Mateusz Mandera cacff28578 types: Fix declared type of custom profile field values.
None of the existing custom profile field types have the value as an
integer like declared in many places - nor is it a string like currently
decalred in types.py. The correct type is Union[str, List[int]]. Rather
than tracking this in so many places throughout the codebase, we add a
new ProfileDataElementValue type and insert it where appropriate.

Mateusz Mandera c4edda016f models: Remove property decorator from UserProfile.profile_data.

Tim Abbott 8fe61674d4 settings: Add web_public_streams_enabled server setting.
This new setting both serves as a guard to allow us to merge API
support for web public streams to main before we're ready for this
feature to be available on Zulip Cloud, and also long term will
protect self-hosted servers from accidentally enabling web-public
streams (which could be a scary possibility for the administrators of
a corporate Zulip server).

shanukun 8c1ea78d7d invite: Extend invite api for handling expiration duration.
This extends the invite api endpoints to handle an extra
argument, expiration duration, which states the number of
days before the invitation link expires.

For prereg users, expiration info is attached to event
object to pass it to invite queue processor in order to
create and send confirmation link.
In case of multiuse invites, confirmation links are
created directly inside do_create_multiuse_invite_link(),

For filtering valid user invites, expiration info stored in
Confirmation object is used, which is accessed by a prereg
user using reverse generic relations.

Tim Abbott 517c2ed39d models: Make realm.name no longer nullable.
This was likely initiall created with null=True in
5c5ffd6ea3 just because we didn't have a
plan for backfilling this field, but I verified that Zulip Cloud has
no realms without a name set, and that's the place most likely to have
any form of super-legacy nameless realms.

So we can clean up this aspect of the data model without a special
migration to do something with existing realms with name=None (which I
suspect would have resulted in a 500 anyway).

Dinesh 430c5cb8e7 user_settings: Create _legacy dicts for existing settings.
Since 84742a0, all settings are sent in the `user_settings` dictionary
which were previously sent inline with other fields in /register
response.

In order to simplify the process of adding new personal settings, we
want to transition to a world where new settings only need to consider
the `property_types` object, and code that needs to reference the
legacy behavior interacts with an object with `legacy` in its name.

This way, contributors working on new settings don't need to think
about the legacy code paths at all.

See https://chat.zulip.org/#narrow/stream/378-api-design/topic/user.20settings.20response.20in.20.2Fregister

Alex Vandiver b011869777 migrations: Add a (profile,end) index on useractivityinterval.
The `user_activity_interval` worker calls:

```python3
    last = UserActivityInterval.objects.filter(user_profile=user_profile).order_by("-end")[0]
`````

Which results in a query like:
```sql
SELECT "zerver_useractivityinterval"."id", "zerver_useractivityinterval"."user_profile_id", "zerver_useractivityinterval"."start", "zerver_useractivityinterval"."end" FROM "zerver_useractivityinterval" WHERE "zerver_useractivityinterval"."user_profile_id" = 12345 ORDER BY "zerver_useractivityinterval"."end" DESC LIMIT 1
```

For users which have at least one matching row, this results in a
query plan like:
```
 Limit  (cost=0.56..711.38 rows=1 width=24) (actual time=0.078..0.078 rows=1 loops=1)
   ->  Index Scan Backward using zerver_useractivityinterval_7f021a14 on zerver_useractivityinterval  (cost=0.56..1031399.46 rows=1451 width=24) (actual time=0.077..0.078 rows=1 loops=1)
         Filter: (user_profile_id = 12345)
         Rows Removed by Filter: 98
 Planning Time: 0.059 ms
 Execution Time: 0.088 ms
```

But for users that have just been created, with no matching rows, this
is considerably more expensive:
```
 Limit  (cost=0.56..711.38 rows=1 width=24) (actual time=10798.146..10798.146 rows=0 loops=1)
   ->  Index Scan Backward using zerver_useractivityinterval_7f021a14 on zerver_useractivityinterval  (cost=0.56..1031399.46 rows=1451 width=24) (actual time=10798.145..10798.145 rows=0 loops=1)
         Filter: (user_profile_id = 12345)
         Rows Removed by Filter: (count of every single row in the table, redacted)
 Planning Time: 0.053 ms
 Execution Time: 10798.158 ms
```

Regular vacuuming can force the use of the index on `user_profile_id`
as long as there are few enough users, which is fast -- however, at
some point, the query planner decides that is insufficiently specific,
always chooses the effective-whole-table-scan.

Add an index on `(user_profile_id, end)`, which is expected to be
sufficiently specific that it is used even with large numbers of user
profiles.

Abhijeet Prasad Bodas de04f0ad67 notifications: Calculate PMs/mentions settings like other settings.
Previously, we checked for the `enable_offline_email_notifications` and
`enable_offline_push_notifications` settings (which determine whether the
user will receive notifications for PMs and mentions) just before sending
notifications. This has a few problem:

1. We do not have access to all the user settings in the notification
handlers (`handle_missedmessage_emails` and `handle_push_notifications`),
and therefore, we cannot correctly determine whether the notification should
be sent. Checks like the following which existed previously, will, for
example, incorrectly not send notifications even when stream email
notifications are enabled-
```
if not receives_offline_email_notifications(user_profile):
    return
```
With this commit, we simply do not enqueue notifications if the "offline"
settings are disabled, which fixes that bug.

Additionally, this also fixes a bug with the "online push notifications"
feature, which was, if someone were to:
* turn off notifications for PMs and mentions (`enable_offline_push_notifications`)
* turn on stream push notifications (`enable_stream_push_notifications`)
* turn on "online push" (`enable_online_push_notifications`)

then, they would still receive notifications for PMs when online.
This isn't how the "online push enabled" feature is supposed to work;
it should only act as a wrapper around the other notification settings.

The buggy code was this in `handle_push_notifications`:
```
if not (
    receives_offline_push_notifications(user_profile)
    or receives_online_push_notifications(user_profile)
):
    return

    // send notifications
```

This commit removes that code, and extends our `notification_data.py` logic
to cover this case, along with tests.

2. The name for these settings is slightly misleading. They essentially
talk about "what to send notifications for" (PMs and mentions), and not
"when to send notifications" (offline). This commit improves this condition
by restricting the use of this term only to the database field, and using
clearer names everywhere else. This distinction will be important to have
non-confusing code when we implement multiple options for notifications
in the future as dropdown (never/when offline/when offline or online, etc).

3. We should ideally re-check all notification settings just before the
notifications are sent. This is especially important for email notifications,
which may be sent after a long time after the message was sent. We will
in the future add code to thoroughly re-check settings before sending
notifications in a clean manner, but temporarily not re-checking isn't
a terrible scenario either.

Abhijeet Prasad Bodas c3319a5231 notification_data: Create common source for trigger strings.
This reduces loose strings in the codebase, and allows us to not worry
about the exact naming (`stream_email_enabled` or `stream_emails_enabled`?)
and tense (`mentioned` or `mention`?).

Ideally this new class should have been in `lib/notification_data.py`,
which is our file for things like this. But, the next commit requires
using this data in `models.py`, and importing from `notification_data.py`
to `models.py` causes recursive imports.

Rohitt Vashishtha 98f8d94b25 linkifiers: Add joint validation for linkifier urls and patterns.
We now validate the linkifier urls and patterns together, and add
the following additional checks:

1. All groups in the pattern must be used in the URL format string.
2. All groups in the URL format string must be declared in the pattern.

Linkifier pattern is now validated inside the `clean` method.
`filter_pattern_validator` is moved from `clean_fields` to `clean`
method as a safe check. As a result of this, a Puppeteer test case
is updated.

NOTE: The changes here are IN ADDITION to the existing validations.

Fixes #16482.

Mateusz Mandera 1a8ad796f8 models: Replace __id syntax with _id where possible.
model__id syntax implies needing a JOIN on the model table to fetch the
id. That's usually redundant, because the first table in the query
simply has a 'model_id' column, so the id can be fetched directly.
Django is actually smart enough to not do those redundant joins, but we
should still avoid this misguided syntax.

The exceptions are ManytoMany fields and queries doing a backward
relationship lookup. If "streams" is a many-to-many relationship, then
streams_id is invalid - streams__id syntax is needed. If "y" is a
foreign fields from X to Y:
class X:
  y = models.ForeignKey(Y)

then object x of class X has the field x.y_id, but y of class Y doesn't
have y.x_id. Thus Y queries need to be done like
Y.objects.filter(x__id__in=some_list)

Tim Abbott 2e928a0853 markdown: Remove logic for creating markdown engines for all realms.
This logic likely never ran due to a combination of bugs.

* Running `maybe_update_markdown_engines` unconditionally meant that
  `if md_engine_key in md_engines` was likely always true.
* Introduced in 65838bb: DEFAULT_MARKDOWN_KEY could never be in
  md_engines, so should we have ever reached that code path, we'd have
  tried to rebuild all markdown engines every time.

And it also wasn't clearly helpful -- because we fetch all linkifiers
for a realm on every request anyway, we don't really save database
queries by doing a bulk fetch on startup, and doing so would likely
result in a material regression to Zulip's overall startup time that
we were creating markdown engines for large numbers of realms in bulk
during process startup.

Abhijeet Prasad Bodas b140c17441 mute user: Cache list of muter IDs.
This commit defines a new function `get_muting_users`
which will return a list of IDs of users who have muted
a given user.
Whenever someone mutes/unmutes  a user, the cache will be
flushed, and subsequently when that user sends a message,
the cache will be populated with the list of people who
have muted them (maybe empty).

This data is a good candidate for caching because-

1. The function will later be called from the message send
codepath, and we try to minimize database queries there.

2. The entries will be pretty tiny.

3. The entries won't churn too much. An average user will
send messages much more frequently than get muted/unmuted,
and the first time penalty of hitting the db and populating
the cache should ideally get amortized by avoiding several
DB lookups on subsequent message sends.

The actual code to call this function will be written in
further commits.

Abhijeet Prasad Bodas 9602aa1467 mute user: Record entries in RealmAuditLog.
This makes it so that RealmAuditLog entries are
created when a user mutes/unmutes someone.

We don't really need to store the time, but we
do so anyways, because the `event_time` field
is currently a non-nullable one in the `RealmAuditLog`
model, and making it nullable would risk allowing
not specifying the time in other more important
code which also creates `RealmAuditLog` entries.

This also fixes an incorrect test of successfully
unmuting with the API. Earlier it did not mock
the time in the `views/muting.py` code to return
`mute_time`.

Sumanth V Rao 1ac8fe7538 events/tests/api: Send realm_playground events to clients.
We send the whole data set as a part of the event rather than
doing an add/remove operation for couple of reasons:
    * This would make the client logic simpler.
    * The playground data is small enough for us to not worry
      about performance.

Tweaked both `fetch_initial_state_data` and `apply_events` to
handle the new playground event.

Tests added to validate the event matches the expected schema.

Documented realm_playgrounds sections inside /events and
/register to support our openapi validation system in test_events.

Tweaked other tests like test_event_system.py and test_home.py
to account for the new event being generated.

Lastly, documented the changes to the API endpoints in
api/changelog.md and bumped API_FEATURE_LEVEL.

Tweaked by tabbott to add an `id` field in RealmPlayground objects
sent to clients, which is essential to sending the API request to
remove one.

WookieMonkeys 1b6f68bb59 stream: Add entropy to deactivated streams.
Adding an additional `!` to the stream name each time a stream is
deactivated, to a maximum of 21 times, effectively limits number of
times a stream with a given name can be deactivated.  This is unlikely
to come up in common usage, but may be confusing when testing.

Change what we prepend to deactivated stream names to something with
more entropy than just `!`, by instead prepending a substring of hash
of the stream's ID.  `!`s.  Using 128 bits of the hash means that it
will require more than 10^18th renames to have a 1% chance of collision.

Because too-long stream names are also truncated at 60 characters,
having this entropy in the beginning of the name also helps address
potential issues from stream names that differed only in, e.g. the
60th character.

Fixes #17016.

Aman Agrawal e587c029f6 display_settings: Allow user to set default_view.
TextField is used to allow users to set long stream + topic narrow
names in the urls.

We currently restrict users to only set "all_messages" and
"recent_topics" as narrows.

This commit achieves 3 things:
* Removes recent topics as the default view which loads when
  hash is empty.
* Loads default_view when hash is empty.
* Loads default_view on pressing escape key when it is unhandled by
  other present UI elements.

NOTE: After this commit loading zulip with an empty hash will
automatically set hash to default_view.  Ideally, we'd just display
the default view without a hash, but that involves extra complexity.

One exception is when user is trying to load an overlay directly,
i.e. zulip is loaded with an overlay hash. In this case,
we render recent topics is background irrespective of default_view.

We consider this last detail to be a bug not important enough to block
adding this setting.

Anders Kaseorg b7b7475672 python: Use standard secrets module to generate random tokens.
There are three functional side effects:

• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.

• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.

• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.

(The base32 alphabet is A-Z 2-7.  We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

    - We change functions like do_create_user,

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.

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.

This allows mypy to catch mismatches between the annotated type of a

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.

This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used

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

status of a user using update_user_backend.

This also adds restriction on removing owner status of the

instead of admin.

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.

The post_init cache-flushing behavior in the original alert words
migration was subtly wrong; while it may have passed tests, it didn't

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

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

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.

following commit, which fixes case-sensitivity issues with Alert Words.

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.

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.

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.

While the result of this change doesn't completely do what we need, it

potential bugs involving Stream and Subscription objects being
represented inconsistently in the API.

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.

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

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.
