Alex Vandiver d55240e543 topic: Add comments calling out case-sensitive index usage. 2023-09-27 10:22:42 -07:00
Hemant Umre be653dd5b4 org_settings: Add backend for `realm_jitsi_server_url` setting.
This commit adds a `jitsi_server_url` field to the Realm model, which
will be used to save the URL of the custom Jitsi Meet server. In
the database, `None` will encode the server-level default. We can't
readily use `None` in the API, as it could be confused with "field not
sent". Therefore, we will use the string "default" for this purpose.

We have also introduced `server_jitsi_server_url` in the `/register`
API. This will be used to display the server's default Jitsi server
URL in the settings UI.

The existing `jitsi_server_url` will now be calculated as
`realm_jitsi_server_url || server_jitsi_server_url`.

Fixes a part of #17914.

Alex Vandiver 3518d31797 migrations: Add indexes with realm_id.
This is designed to help PostgreSQL have better specificity and
locality in its indexes.  Subsequent commits will adjust the code to
make sure that we use these indexes rather than the `realm_id`-less
versions.

We do not add a `realm_id` variation to the full-text index, since
it is a GIN index; multi-column GIN indexes are not terribly
performant, require the `btree_gin` extension for `int` types (which
requires superuser privileges on PostgreSQL 12 and earlier), and
cannot be consistently added concurrently on running instances.

After all indexes have been made, we also run `CREATE STATISTICS` in
order to give PostgreSQL the opportunity to realize that recipient and
sender are highly correlated with message realm, allowing it to
estimate that `(realm_id, recipient_id)` is likely as specific as
matching a given `recipient_id`, instead of as likely as matching
`realm_id` times matching a `recipient_id`.  Finally, those statistics
must be filled by `ANALYZE zerver_message`, which is run last.

Anders Kaseorg 2cd018ce57 models: Remove duplicate index definition for date_sent.
Commit cf0eb46afc added this to let
Django understand the CREATE INDEX CONCURRENTLY statement that had
been hidden in a RunSQL query in migration 0244.  However, migration
0245 explained that same index to Django in a different way by setting
db_index=True.  Move that to 0244 where the index is actually created,
using SeparateDatabaseAndState.

Also remove the part of the SQL in 0245 that was mirrored by dummy
state_operations, and replace it with real operations.

Sahil Batra 7295028194 message: Access realm object directly from message.
We can directly get the realm object from Message object now
and there is no need to get the realm object from "sender"
field of Message object.

After this change, we would not need to fetch "sender__realm"
field using "select_related" and instead only passing "realm"
to select_related when querying Message objects would be enough.

This commit also updates a couple of cases to directly access
realm ID from message object and not message.sender. Although
we have fetched sender object already, so accessing realm_id
from message directly or from message.sender should not matter,
but we can be consistent to directly get realm from Message
object whenever possible.

Zixuan James Li 30495cec58 migration: Rename extra_data_json to extra_data in audit log models.
This migration applies under the assumption that extra_data_json has
been populated for all existing and coming audit log entries.

- This removes the manual conversions back and forth for extra_data
throughout the codebase including the orjson.loads(), orjson.dumps(),
and str() calls.

- The custom handler used for converting Decimal is removed since
DjangoJSONEncoder handles that for extra_data.

- We remove None-checks for extra_data because it is now no longer
nullable.

- Meanwhile, we want the bouncer to support processing RealmAuditLog entries for
remote servers before and after the JSONField migration on extra_data.

- Since now extra_data should always be a dict for the newer remote
server, which is now migrated, the test cases are updated to create
RealmAuditLog objects by passing a dict for extra_data before
sending over the analytics data. Note that while JSONField allows for
non-dict values, a proper remote server always passes a dict for
extra_data.

- We still test out the legacy extra_data format because not all
remote servers have migrated to use JSONField extra_data.
This verifies that support for extra_data being a string or None has not
been dropped.

Zixuan James Li 37660dd0e7 linkifier: Support reordering linkifiers.
This adds API support to reorder linkifiers and makes sure that the
returned lists of linkifiers from `GET /events`, `POST /register`, and
`GET /realm/linkifiers` are always sorted with the order that they
should processed when rendering linkifiers.

We set the new `order` field to the ID with the migration. This
preserves the order of the existing linkifiers.

New linkifiers added will always be ordered the last. When reordering,
the `order` field of all linkifiers in the same realm is updated, in
a manner similar to how we implement ordering for
`custom_profile_fields`.

Steve Howell 51db22c86c per-request caches: Add per_request_cache library.
We have historically cached two types of values
on a per-request basis inside of memory:

    * linkifiers
    * display recipients

Both of these caches were hand-written, and they
both actually cache values that are also in memcached,
so the per-request cache essentially only saves us
from a few memcached hits.

I think the linkifier per-request cache is a necessary
evil. It's an important part of message rendering, and
it's not super easy to structure the code to just get
a single value up front and pass it down the stack.

I'm not so sure we even need the display recipient
per-request cache any more, as we are generally pretty
smart now about hydrating recipient data in terms of
how the code is organized. But I haven't done thorough
research on that hypotheseis.

Fortunately, it's not rocket science to just write
a glorified memoize decorator and tie it into key
places in the code:

    * middleware
    * tests (e.g. asserting db counts)
    * queue processors

That's what I did in this commit.

This commit definitely reduces the amount of code
to maintain. I think it also gets us closer to
possibly phasing out this whole technique, but that
effort is beyond the scope of this PR. We could
add some instrumentation to the decorator to see
how often we get a non-trivial number of saved
round trips to memcached.

Note that when we flush linkifiers, we just use
a big hammer and flush the entire per-request
cache for linkifiers, since there is only ever
one realm in the cache.

We generally want to avoid extra moving parts when we

stringify DM and huddle objects, and it's kind of ugly
how we do it, but that's outside the scope of my

This commit adds code to pass all the required arguments to
select_related call for Message objects such that only the

Previously, we did not pass any arguments to select_related,
so all the directly and indirectly related fields were fetched

As a result of this change, we do not fetch the recipient from
Huddle object but instead get it using the "id" and "recipient_id"
fields available from Huddle object like we do for a personal
message. This change allows us to not fetch recipient object
using select_related when querying the Huddle object.

related objects were being fetched, with no non-null related fields

This commit adds code to pass stream traffic data using
the "stream_weekly_traffic" field in stream objects.

We already include the traffic data in Subscription objects,
but the traffic data does not depend on the user to stream
relationship and is stream-only information, so it's better
to include it in Stream objects. We may remove the traffic
data and other stream information fields for Subscription
objects in future.

traffic data in case where client receives a stream
creation event and no subscription event, for an already
existing stream which the user did not have access to before.

Alex Vandiver b67108c8c6 retention: Prevent deletion of partially-archived messages.
Previously, this code:
```python3
old_archived_attachments = ArchivedAttachment.objects.annotate(
    has_other_messages=Exists(
        Attachment.objects.filter(id=OuterRef("id"))
        .exclude(messages=None)
        .exclude(scheduled_messages=None)
    )
).filter(messages=None, create_time__lt=delta_weeks_ago, has_other_messages=False)
```

...protected from removal any ArchivedAttachment objects where there
was an Attachment which had _both_ a message _and_ a scheduled
message, instead of _either_ a message _or_ a scheduled message.
Since files are removed from disk when the ArchivedAttachment rows are
deleted, this meant that if an upload was referenced in two messages,
and one was deleted, the file was permanently deleted when the
ArchivedMessage and ArchivedAttachment were cleaned up, despite being
still referenced in live Messages and Attachments.

Switch from `.exclude(messages=None).exclude(scheduled_messages=None)`
to `.exclude(messages=None, scheduled_messages=None)` which "OR"s
those conditions appropriately.

Pull the relevant test into its own file, and expand it significantly
to cover this, and other, corner cases.

Sahil Batra c11cf8eb54 users: Directly access id of foreign keys instead of full object.
We used to access the complete objects for UserProfile foreign
keys like "bot_owner" and "default_sending_stream", where we only
needed ID of them.

This commit fixes some of such instances and now we directly get
the id using "bot_owner_id" and "default_sending_stream_id" so
that we can avoid the unnecessary complexity of accessing the
complete object.

Sahil Batra 3e09a21929 models: Pass realm and bot_owner as args to select_related.
This commit updates the select_related calls in queries to get
UserProfile objects in get_user, get_user_by_delivery_email,
get_user_profile_by_id, get_user_profile_by_id_in_realm and
get_user_profile_by_api_key functions to pass "realm" and
"bot_owner" as arguments to select_related call.

These functions are used in different parts of code to get
the UserProfile object and realm is accessed using the user
object at many places.

"bot_owner" field is also used in some places like to check
whether a bot can access a stream, to check whether a user
can change modify another user, in webhooks code to send the
message to the bot owner, and in tests as well. There can be
some places where the bot owner is not required and in most
such cases the code would only be accessed for human users,
which means the bot_owner will be null for these cases and
would avoid complexity and performance issues.

Note that previously, no arguments were passed to select_related
and thus only realm field was fetched during the query.

This commit updates the select_related calls in queries to
get UserProfile object in get_syste_bot function pass "realm"
as argument to select_related call.

The "get_system_bot" call function is mostly used to get cross
realm bot which are used as senders to send messages.
The fields like default_events_register_stream and recipient
are not required for these cases. The bot_owner field is used
to check access to a stream to send message but the cross-realm
bots are handled differently and the bot_owner check is not
required.

Also, note that "realm" is the only non-null foreign key field
in UserProfile object, so select_related() was only fetching
realm object previously as well. But we should still pass
"realm" as argument in select_related call so that we can make
sure that only required fields are selected in case we add
more foreign keys to UserProfile in future.

The user object from get_active_users was used to get realm

directly use that realm object. This change also leads to
some changes in the cache code where we now pass the realm
to the function instead of selecting it from UserProfile object.

Steve Howell d19c1f7438 message fetching: Avoid duplicate cache layers.
This code removes a lot of complexity with very likely
positive overall impact on system performance and
negligible downside.

We already cache display recipients on a per-user
level, so there's no need for another cache layer on
top of that that keys them with recipient ids.

We avoid strange things where Alice/Bob and Bob/Charlie
get put into the top layer cache and then we still have
a cache miss on Alice/Charlie despite the lower level
cache being able to support per-user lookups.

This change does introduce an extra database round trip
if any of our messages have a huddle, but the query is
extremely cheap, and we can always try to cache that
function more directly or try to re-use some of our
other huddle-based caches.

As part of this, we clean up the names for the
lower-level per-user cache of display recipients, and
we simplify the cache keys.

We also stop passing in a full Recipient object to the
`bulk_get_huddle_user_ids` functions.

The local impact of this change should be easy to
measure (at least approximately), since we use this
function every time a user gets messages via the
/messages endpoint.

Steve Howell b742f1241f realm emoji: Use a single cache for all lookups.
The active realm emoji are just a subset of all your
realm emoji, so just use a single cache entry per
realm.

Cache misses should be very infrequent per realm.

If a realm has lots of deactivated realm emoji, then
there's a minor expense to deserialize them, but that
is gonna be dwarfed by all the other more expensive
operations in message-send.

I also renamed the two related functions.  I erred on
the side of using somewhat verbose names, as we don't
want folks to confuse the two use cases. Fortunately
there are somewhat natural affordances to use one or
the other, and mypy helps too.

Finally, I use realm_id instead of realm in places
where we don't need the full Realm object.
