Zixuan James Li 641f60305d realm_playgrounds: Add url_template field.
As an intermediate step before we fully support url_template for realm
playgrounds, we populate url_template in the backend ensuring that all
the new entries will be validated. With a later backfilling migration,

we prepare the database such that all the records will have a valid URL
template.

Lauryn Menard 1cccdd8103 realm-settings: Make default_code_block_language empty string as default.
Updates the realm field `default_code_block_language` to have a default
value of an empty string instead of None. Also updates the web-app to
check for the empty string and not `null` to indicate no default is set.

This means that both new realms and existing realms that have no default
set will have the same value for this setting: an empty string.

Previously, new realms would have None if no default was set, while realms
that had set and then unset a value for this field would have an empty
string when no default was set.

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.

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.
2023-07-19 11:07:33 -07:00
Steve Howell 03557a5568 huddles: Find huddle user ids more efficiently.
We restrict the columns, avoid quadratic looping,
and don't bother with order_by.

We also return the user ids (per recipient) as
sets, since that's how the only caller uses the
info (albeit implicitly via set.union accepting
a list).

Prakhar Pratyush 21a5818765 mention: Soft-reactivate users receiving @topic mention notifications.
The long-term idle topic participants are soft-reactivated

Steve Howell 67cdf1a7b4 emojis: Use get_emoji_data.
The previous function was poorly named, asked for a
Realm object when realm_id sufficed, and returned a
tuple of strings that had different semantics.

I also avoid calling it duplicate times in a couple
places, although it was probably rarely the case that
both invocations actually happened if upstream
validations were working.

Note that there is a TypedDict called EmojiInfo, so I
chose EmojiData here.  Perhaps a better name would be
TinyEmojiData or something.

I also simplify the reaction tests with a verify
helper.

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.

migrations: Backfill extra_data_json for audit log entries.
This migration is reasonably complex because of various anomalies in existing
data.

Note that there are cases when extra_data does not contain data that is
proper json with possibly single quotes. Thus we need to use
"ast.literal_eval" to cover that.

There is also a special case for "event_type == USER_FULL_NAME_CHANGED",
where extra_data is a plain str. This event_type is only used for
RealmAuditLog, so the zilencer migration script does not need to handle
it.

The migration does not handle "event_type == REALM_DISCOUNT_CHANGED"
because ast.literal_eval only allow Python literals. We expect the admin
to populate the jsonified extra_data for extra_data_json manually
beforehand.

This chunks the backfilling migration to reduce potential block time.

The migration for zilencer is mostly similar to the one for zerver; except that
the backfill helper is added in a wrapper and unrelated events are
removed.

**Logging and error recovery**

We print out a warning when the extra_data_json field of an entry
would have been overwritten by a value inconsistent with what we derived
from extra_data. Usually this only happens when the extra_data was
corrupted before this migration. This prevents data loss by backing up
possibly corrupted data in extra_data_json with the keys
"inconsistent_old_extra_data" and "inconsistent_old_extra_data_json".
More roundtrips to the database are needed for inconsistent data, which are
expected to be infrequent.

This also outputs messages when there are audit log entries with decimals,
indicating that such entries are not backfilled. Do note that audit log
entries with decimals are not populated with "inconsistent_old_extra_data_*"
in the JSONField, because they are not overwritten.

For such audit log entries with "extra_data_json" marked as inconsistent,
we skip them in the migration.  Because when we have discovered anomalies in a
previous run, there is no need to overwrite them again nesting the extra keys
we added to it.

**Testing**

We create a migration test case utilizing the property of bulk_create
that it doesn't call our modified save method.

We extend ZulipTestCase to support verifying console output at the test
case level. The implementation is crude but the use case should be rare
enough that we don't need it to be too elaborate.

user groups. This gets audited as well.

Alex Vandiver d87895a3ef missed-message: Merge before calling handle_missedmessage_emails.
The MissedMessage queue worker is the single callsite of
`handle_missedmessage_emails`, which immediately transforms the list

Skip the intermediate list step, and use defaultdict and a dataclass
to simplify and make explicit the pieces.  This removes the unused
user_profile_id and message_id pieces of the data structure.

Prakhar Pratyush 0891f9f65a mention: Determine @topic mention during message rendering.
This commit adds a boolean field `mentions_topic_wildcard`
to the `MessageRenderingResult` dataclass.

The field is set to true only if message rendering determines
the message has an actual topic wildcard mention in it (and not,
e.g., topic wildcard mention syntax inside a code block).

The rendered content for topic wildcard mention is
'<span class="topic-mention">{wildcard}</span>'.

The 'topic-mention' class is the identifier for the wildcard
mention being a topic wildcard mention.

We don't use 'data-user-id="*"' and "user-mention" class for
topic wildcard mentions and eventually plan to remove them for
stream wildcard mentions too in a separate mini-project.

Prakhar Pratyush 806d8f2dc7 test_markdown: Merge similar tests into a single test case.
This prep commit merges separate tests for '**@all**',

into a single test named 'test_mention_stream_wildcard'.

Similarly, it merges separate tests for '@all', '@stream',
and '@everyone' stream wildcard mentions into a single test
named 'test_mention_at_stream_wildcard'.

The aim is to finally have two separate tests for stream and
topic wildcard mentions (when we introduce topic wildcards)
instead of having separate tests for each mention text
(i.e. all, everyone, stream, topic).

Topic participants are anyone who sent a message to a topic
or reacted to a message on the topic.

'topic_wildcard_mention_in_followed_topic_user_ids' stores the
ids of the topic participants who follow the topic and have

Steve Howell 89381a8072 cache: Eliminate get-stream-by-name cache.
We remove the cache functionality for the
get_realm_stream function, and we also change it to
return a thin Stream object (instead of calling
select_related with no arguments).

The main goal here is to remove code complexity, as we
have been prone to at least one caching validation bug
related to how Realm and UserGroup interact. That
particular bug was more theoretical than practical in
terms of its impact, to be clear.

Even if we were to be perfectly disciplined about only
caching thin stream objects and always making sure to
delete cache entries when stream data changed, we would
still be prone to ugly situations like having
transactions get rolled back before we delete the cache
entry. The do_deactivate_stream is a perfect example of
where we have to consider the best time to unset the
cache. If you unset it too early, then you are prone to
races where somebody else churns the cache right before
you update the database. If you set it too late, then
you can have an invalid entry after a rollback or
deadlock situation. If you just eliminate the cache as
a moving part, that whole debate is moot.

As the lack of test changes here indicates, we rarely
fetch streams by name any more in critical sections of
our code.

The one place where we fetch by name is in loading the
home page, but that is **only** when you specify a
stream name. And, of course, that only causes about an
extra millisecond of time.

Steve Howell 046e4c715b cache: Use DB for all bulk get-stream-by-name queries.
This changes bulk_get_streams so that it just uses the
database all the time.  Also, we avoid calling
select_related(), so that we just get back thin and
tidy Stream objects with simple queries.

About not caching any more:

It's actually pretty rare that we fetch streams by name
in the main application. It's usually API requests that
send in stream names to find more info about streams.

It also turns out that for large queries (>= ~30 rows
for my measurements) it's more efficent to hit the
database than memcached. The database is super fast at
scale; it's just the startup cost of having Django
construct the query, and then having the database do
query planning or whatever, that slows us down. I don't
know the exact bottleneck, but you can clearly measure
that one-row queries are slow (on the order of a full
millisecond or so) but the marginal cost of additional
rows is minimal assuming you have a decent index (20
microseconds per row on my droplet).

All the query-count changes in the tests revolve around
unsubscribing somebody from a stream, and that's a
particularly odd use case for bulk_get_streams, since
you generally unsubscribe from a single stream at a
time. If there are some use cases where you do want to
unsubscribe from multiple streams, we should move
toward passing in stream ids, at least from the
application. And even if we don't do that, our cost for
most queries is a couple milliseconds.

Steve Howell 87d1208d53 tests: Improve test for default stream groups. 2023-07-10 13:41:28 -07:00
Steve Howell 8894ff89ac signup: Extract set_up_streams_for_new_human_user.
We extract code from process_new_human_user with
no modifications.

This has all the best outcomes of extracting a function:

    * better profile info
    * easier to test for query counts (signup gets real noisy)
    * simplifies a long, messy function

It has no real drawbacks, since the helper function doesn't need
to pass back any intermediate state to the parent for the rest
of what the parent does.

When you profile test_signup and test_invite, with a decent
sample size, the set_up_streams_for_new_human_user function
does about 20% of the work for process_new_human_user, which
is a lot considering that most tests don't create a ton of
pre-registered or default streams.

Steve Howell d6ef94f63f page load: Improve default_streams performance.
At least as measured by test_events.py, which has over 1000
calls to fetch initial data for page loads, this should
be about a 10% improvement in how much time the server
spends fetching data.

We mostly avoid a select_related() query that did this nastiness:

    INNER JOIN "zerver_realm" ON ("zerver_stream"."realm_id" = "zerver_realm"."id")
    INNER JOIN "zerver_usergroup" ON ("zerver_stream"."can_remove_subscribers_group_id" = "zerver_usergroup"."id")
    INNER JOIN "zerver_realm" T4 ON ("zerver_usergroup"."realm_id" = T4."id")
    INNER JOIN "zerver_usergroup" T5 ON ("zerver_usergroup"."can_mention_group_id" = T5."id")
    INNER JOIN "zerver_realm" T6 ON (T5."realm_id" = T6."id")
    INNER JOIN "zerver_usergroup" T7 ON (T5."can_mention_group_id" = T7."id")
    INNER JOIN "zerver_realm" T8 ON (T7."realm_id" = T8."id")
    INNER JOIN "zerver_usergroup" T9 ON (T7."can_mention_group_id" = T9."id")
    INNER JOIN "zerver_realm" T10 ON (T9."realm_id" = T10."id")
    INNER JOIN "zerver_usergroup" T11 ON (T9."can_mention_group_id" = T11."id")
    WHERE "zerver_stream"."id" IN (SELECT U0."stream_id" FROM "zerver_defaultstream" U0 WHERE U0."realm_id" = 2

2023-07-10 13:41:28 -07:00
Steve Howell 763b5e0741 default streams: Extract library functions.
I created zerver/lib/default_streams.py, so that various
views and events.py don't have to awkwardly reach into
an "actions" file.

I copied over two functions verbatim from actions/default_streams.py:

    get_default_streams_for_realm
    streams_to_dicts_sorted

The latter only remains as an internal detail in the new library.

I also created two new helpers:

    get_default_stream_ids_for_realm:

        This is both faster and easier to use in all the places
        where we only need to get a set of default stream ids.

    get_default_streams_for_realm_as_dicts:

        This just wraps the prior calls to
        streams_to_dicts_sorted(get_default_streams_for_realm(...)),
        and it doesn't yet address the slowness of the underlying
        code.

        All the "real" code should be functionally the same.

        In a few tests I now use this wrapper instead of
        calling get_default_streams_for_realm, just to get
        slightly deeper coverage.

Prakhar Pratyush 179d5cb37d mention: Replace 'wildcards' with 'stream_wildcards'.
This prep commit replaces the 'wildcard' keyword in the codebase
with 'stream_wildcard' at some places for better readability, as
we plan to introduce 'topic_wildcards' as a part of the
'@topic mention' project.

Currently, 'wildcards = ["all", "everyone", "stream"]' which is an
alias to mention everyone in the stream, hence better renamed as
'stream_wildcards'.

Eventually, we will have:
'stream_wildcard' as an alias to mention everyone in the stream.
'topic_wildcard' as an alias to mention everyone in the topic.
'wildcard' refers to 'stream_wildcard' and 'topic_wildcard' as a whole.

Steve Howell ae9303ab3f doc tests: Remove landing_missing_strings.
dbe930394f changed the
"missing string" from "Log in" to "xyz" for some
unknown reason.  The current code makes no sense.

Also, even the original test code here had the common
pitfall of only testing one side of the condition.
Presumably if you are testing that a certain string
is missing in a landing-page scenario, then you also
want to check that it **does** exist in other
scenarios.  Otherwise, the flag would have been
named something more generic. Of course, I am mostly
guessing due to lack of comments.

If there is some test logic here that we need to
resurrect, then we should just write a custom test
for the /hello page rather than crufting up
all our helpers.

For the two strange exceptions to the normal policy,
I now handle them together in the helper function with
a comment.

I also disentangle the logic to look for og tags from
the robot logic, and this should also lead to more
thorough testing.

There is some code duplication between the two new

Steve Howell cea5e67262 narrows: Use dataclasses in a couple internal functions.
This is a first step toward two goals:
    * support dictionary-like narrows when registering events
    * use readable dataclasses internally

This is gonna be a somewhat complicated exercise due to how
events get serialized, but fortunately this interim step
doesn't require any serious shims, so it improves the codebase
even if the long-term goals may take a while to get sorted
out.

The two places where we have to use a helper to convert narrows
from tuples to dataclasses will eventually rely on their callers
to do the conversion, but I don't want to re-work the entire
codepath yet.

Note that the new NarrowTerm dataclass makes it more explicit
that the internal functions currently either don't care about
negated flags or downright don't support them.  This way mypy
protects us from assuming that we can just add negated support
at the outer edges.

OTOH I do make a tiny effort here to slightly restructure
narrow_filter in a way that paves the way for negation support.

The bigger goal by far, though, is to at least support the
dictionary format.

Steve Howell d64d1c81a4 tests: Eliminate narrow.json fixture.
In 2484d870b4 I created tests
using a fixture called narrow.json.  I believe my intention
was to eventually use the fixture for similar tests on the
frontend, but that never happened.

Almost seven years later, I think it's time to just use
straightforward code in Python to test build_narrow_filter.
In particular, we want to move to dataclasses, so that would
create an addition nuisance for fixture-based tests.  The
fixture was already annoying in terms of being an extra moving
part, being hard to read, and not being type-safe.

In order to avoid typos, I mostly code-generated the new
Python code by instrumenting the old test:

                 narrow_filter = build_narrow_filter(narrow)
    +            print("###\n")

Steve Howell 8ea0c5bbad narrow_filter: Pass message/flags to narrow_filter.
We no longer pass in a big opaque event to narrow_filter
(which is inside build_narrow_filter). We instead explicitly
pass in message and flags. This leads to a bit more type
safety, and it's also more flexible. There's no reason to
build an entire event just to see if a message belongs to
a narrow.

The changes to the test work around the fact that the fixtures
are sloppy with types. I plan a subsequent commit to clean
up those tests significantly.

Ujjawal Modi f7346f36fc attachments: Refactor code for flushing used_upload_space cache.
Subsequent commits will add "on_delete=models.RESTRICT"
relationships, which will result in the Attachment
objects being deleted after Realm has been deleted from
the database.

In order to handle this, we update
get_realm_used_upload_space_cache_key function to accept
realm_id as parameter instead of realm object, so that
the code for flushing the cache works even after the
realm is deleted. This change is fine because eventually
only realm_id is used by this function and there is no
need of the complete realm object.
