We remove bot's subscriptions for private streams to which the
new owner is not subscribed and keep the ones to which the new
owner is subscribed on changing owner.
This commit also changes the code for sending subscription
remove events to use transaction.on_commit since we call
the function inside a transactopn in do_change_bot_owner and
this also requires some changes in tests in test_events.
For topic wildcard mentions, the 'wildcard_mentioned' flag is set
for those user messages having 'user_profile_id' in
'topic_participant_user_ids', i.e. all topic participants.
Earlier, the flag was set if the 'user_profile_id' exists in
'all_topic_wildcard_mention_user_ids'.
'all_topic_wildcard_mention_user_ids' contains the ids of those
users who are topic participants and have enabled notifications
for '@topic' mentions.
The earlier approach was incorrect, as it would set the
'wildcard_mentioned' flag only for those topic participants
who have enabled the notifications for '@topic' mention instead
of setting the flag for all the topic participants.
The bug was introduced in 4c9d26c.
This commit addresses the issue where the topic highlighting
in search results was offset by one character when an
apostrophe was present. The problem stemmed from the disparity
in HTML escaping generated by the function `func.escape_html` which
is used to obtain `topic_matches` differs from the escaping performed
by the function `django.utils.html.escape` for apostrophes (').
func.escape_html | django.utils.html.escape

To fix this SQL query is changed to return the HTML-escaped
topic name generated by the function `func.escape_html`.
Fixes: #25633.
Currently, we are displaying the "Complete the organization profile"
banner immediately after the organization was created. It's important to
strongly encourage orgs to configure their profile, so we should delay
showing the banner if the profile has not been configured after 15 days.
Thus also allows the users to check out Zulip and see how it works before
configuring the organization settings.
Fixes: #24122.
The number of affected objects may be quite high, and they are
selected by `id IN (...)` query, and updated with a giant `CASE`.
This turns out to be quadratic, and can cause large queries to take
hours, in a state where they cannot be terminated, when PostgreSQL >11
tries to JIT the query.
Set a batch_size as a stopgap performance fix before moving to
`.update()` as a real fix.
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 want to phase out the use of get_display_recipient
for streams, and this is the last place that I
eliminate it. The next commit will eliminate the
dead code and make mypy types tighter.
This change will make push notifications slightly
slower in some situations, but we avoid all the
complexity of a cache, and this code tends to run
offline.
We could always make this code a bit more efficient
by being a little smarter about what data we fetch
up front. For example, get_apns_alert_title gets
called by a function that already has the stream
name. It's just a bit of a pain to refactor when
you have all the DM codepath mucked up with the
stream codepath.
There's no need for the complexity and extra round
trips to call get_display_recipient in a testing
context.
We also eliminate the unnecessary call to check_string.
This function is poorly named, but that's a sweep
for another day.
The get_display_recipient helper is a clumsy way to get
stream names, and it's not even representative of how
most of our code retrieves stream names.
The new helper also double-checks that the Stream
object has the correct recipient id.
We no longer have to reason about the 12 possible
ways of invoking get_narrow_url. We also avoid
double computation in a couple places.
Finally, we get stricter type checks by just inlining
the calls.
We don't need to call get_display_recipient for
non-stream messages.
I will rename display_recipient in the next commit;
if I were to combine the steps the diff would be too
hard to read.

We only need ID of the recipient and not the full object, so we

This commit removes get_huddle_recipient function and we now use
get_or_create_huddle in get_recipient_from_user_profiles.
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.
We now fetch recipient object when querying "Huddle" object in
get_or_create_huddle_backend as this query is eventually used
to get the recipient object only in get_huddle_recipient.
This commit also updates the select_related call in the code to
populate Huddle objects in cache to pass "Recipient" as argument.
Previously no argument was passed to select_related and thus no
related objects were being fetched, with no non-null related fields
being present.
- Adds instructions block and relative link to Starred messages.

The set of objects in the `users` object can be very large (in some
cases, literally every object in the database) and making them into a
giant `id in (...)` to handle the one tiny corner case which we never
use is silly.
Switch the `--users` codepath to returning a QuerySet as well, so it
can be composed. We pass a QuerySet into send_custom_email as well,
so it can ensure that the realm is `select_related` in as well, no
matter how the QuerySet was generated.
Substituting the rendered body via Jinja2 means that it cannot
perform any interpolation itself. While the string replacement is
hacky, it is the only solution which avoids running Jinja2 more than
once, and also allows the user-supplied content to have Jinja2
substitutions in it.
In this commit, we introduce a new option in the stream creation
UI - a 'Default stream for new users' checkbox. By default, the
checkbox is set to 'off' and is only visible to admins. This
allow admins to easily designate a stream as the default stream
for new users during stream creation.
Fixes#24048.
Adds a test for when a value for a user's custom profile field is
removed and not set to a new value. The omission of this event in
the tests was noted as a possibility in #22103, which updated the
API documentation for these events having `null` for the field
value.
When adding the test discovered that the events logic was not
deleting the field from the user object and instead setting it to
`None`, so fixes that logic as well. There was a similar bug fixed
in commit 96c61a1a41 for when custom profile fields are removed
from a realm.
When applying realm_user update events, some of the event fields
for the person object were being updated to the same value in a
loop. Unnests those calls from the loop over the existing fields
so that they are only updated once.
The original nesting was introduced in commit 649fccde6b and
was expanded in other additions to the logic for these events.
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.
This will help clients to correctly display the stream
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.
This commit changes the code to not use get_client_data
function and instead use `stream_to_dict` function to
get the stream data in a dictionary form. This is a
prep commit add stream traffic data to Stream objects.
This commit adds stream_to_dict method which is same as
Stream.to_dict method as of now. This is a prep commit
to include stream traffic data in stream objects.
I move the helper user_ids_to_users to the only
place that it's used, and then I simplify it to
do a direct database query.
These endpoints aren't hit often enough to justify
caching complexity, and for really large user groups,
hitting the cache can actually be counterproductive.
Particularly when you add new users to an existing
group, the bulk of the cost is sending out
notification messages to users.
The only change to the test is that I added an
assertion on the query count.
The cross-realm bots rarely change, and there are only
a few of them, so we just query them all at once and
put them in the cache.
Also, we put the dictionaries in the cache, instead of
the user objects, since there is nothing time-sensitive
about the dictionaries, and they are small. This saves
us a little time computing the avatar url and things
like that, not to mention marshalling costs.
This commit also fixes a theoretical bug where we would
have stale cache entries if somebody somehow modified
the cross-realm bots without bumping KEY_PREFIX.
Internally we no longer pre-fetch the realm objects for
the bots, but we don't get overly precise about picking
individual fields from UserProfile, since we rarely hit
the database and since we don't store raw ORM objects
in the cache.
The test diffs make it look like we are hitting the
cache an extra time, but the tests weren't counting
bulk fetches. Now we only use a single key for all
bots rather a key per bot.
The bulk_get_users() function was only being used to
get cross-realm bots.
It appears that it was introduced in
f02e5b90f6 for that
specific use case.
Now we make the function more specific and test it more
accurately.
We also eliminate a lot of janky code and comments,
including some code that never had test coverage.
Incidentally, it appears that we did not have any code
to invalidate the cache keys here, and that is still
the case. In practice I assume people rarely
re-configure their cross-realm bots unless they are
upgrading the server, and then KEY_PREFIX comes into
play. 25fd4c5508 seems
to have caused that hopefully harmless regression.
A further step will be to make this cache more coarse,
since there are only a few cross-realm bots. The next
commit will hopefully simplify the code and address the
validation pitfall.
Earlier the API endpoints related to user_group accepts and returns a
field `can_mention_group_id` which represents the ID
of user_group whose members can mention the group.
This commit renames this field to `can_mention_group`.
Earlier the API endpoints related to streams accepts and returns a
field `can_remove_subscribers_group_id` which represents the ID
of user_group whose members can remove subscribers from stream.
This commit renames this field to `can_remove_subscribers_group`.
Dropping support for url_prefix for RealmPlayground, the server now uses

This commit removes the stray strings used to refer to
various types of notification triggers.
We use the attributes of the 'NotificationTriggers' class instead.
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.
Expands support for the message ID operand for id" operator to be either
a string or an integer. Previously, this operand was always validated as

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.
This commit updates code to pass "realm" and "bot_owner" args to
select_related call in get_users. We pass "realm" and "bot_owner"
args to get_users because the caches which this function is used
to populate are used for get_user and get_user_profile_by_api_key
functions and they also select both these fields when querying for
UserProfile objects.
This commit updates the select_related calls in queries to
get UserProfile objects in get_user function called in
management commands to pass "realm" as argument to
select_related call.
There are some management commands like deactivate_user,
change_full_name, etc. which might need fields like
"default_sending_stream" when changing full name of a bot
or something similar, but we don't think that would happen
often and we can afford to have a DB round trip to get
these fields if needed.
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.
This commit updates select_related call to pass "realm" as
argument in select_related call in fetch_users_by_id function
as we only require realm for the UserProfile objects fetched
using fetch_users_by_id.
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.
We do not use any related fields for the UserProfile objects
fetched by get_active_users, so we can simply remove the
select_related call.
The user object from get_active_users was used to get realm
but since get_active_users called from a realm object we can
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.
This commit removes select_related call from
get_soft_deactivated_users_for_catch_up as
we do not use any related fields for the
UserProfile objects fetched using this call.

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.
The only overlap between how we fetched streams and
users was to share some really complicated data
structures.
We can also short-circuit some logic if a message
batch is either all-stream or all-DM.
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).
It’s unclear what was supposed to be “safe” about this wrapper. The
hashlib API is fine without it, and we don’t want to encourage further
use of SHA-1.

- Adds `message_handle_match` function to handle new pattern for
relative help links to "Drafts" and "Scheduled messages" for logged-in

`remove_denormalized_recipient_column_from_data` removes the
`recipient` data from `zerver_userprofile`, but did not remove it from
`zerver_userprofile_mirrordummy`, which was later appended to the list
of `zerver_userprofile` objects. This led to failure when inserting,
as the mirrordummy objects still tried to reference their previous
`recipient_id`s.
Move the merging of the two sets earlier, before we call
`remove_denormalized_recipient_column_from_data`.
If there are two huddles, with users A + B + C + D and A + B + C, and
user D is deleted, it is replaced with a mirrordummy user. If
mirrordummy subscriptions are not included in exports, then the two
huddles have duplicate member sets, and will not be able to be
imported successfully.
Include huddle subscriptions for mirrordummy users in exports.
The long-term idle topic participants are soft-reactivated
after email/push notifications are sent due to @topic mention.
The reason being that, generally, @topic mentions are going to
reach a small set of users who have a decent chance of being
reactivated by the notifications.
This commit completes the notifications part of the @topic
wildcard mention feature.
Notifications are sent to the topic participants for the
@topic wildcard mention.
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.
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.
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.

This tracks user group membership changes when the realm is first set
up, either through an import or not. This happens when we add users to
the system user groups by their roles.
For an imported realm, we do extra handling when the data doesn't include
user groups. This gets audited as well.
Django seems to have an aggressive check on the type of a field when
setting it through an relation, requiring the argument to be a UserGroup in
our case.

The MissedMessage queue worker is the single callsite of
`handle_missedmessage_emails`, which immediately transforms the list
of events into a dict keyed by message-id.
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.
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.
This commit adds the 'topic_wildcard_mention_user_ids' and
'topic_wildcard_mention_in_followed_topic_user_ids'
attributes to the 'RecipientInfoResult' dataclass.
Only topic participants are notified of @topic mentions.
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
enabled the wildcard mention notifications for followed topics.
'topic_wildcard_mention_user_ids' stores the ids of the topic
participants for whom 'user_allows_notifications_in_StreamTopic'
with setting 'wildcard_mentions_notify' returns True.
This commit adds a 'has_topic_wildcards' instance variable
to the 'MentionData' class for the detection of

"stream:" prefix for stream based groups in future.
Fixes part of #26148.
Previously we had database level restriction on length of
user group names. Now we add the same restriction to API
level as well, so we can return a better error response.
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.
We want to avoid Django going back to the database to
get a realm object that the caller already has.
It's actually currently the case that we often
pre-fetch realm objects when we get stream objects
using get_stream (using a call to select_related() with
no arguments), but that is an expensive operation that
we want to avoid going forward.
This commit prepares us to just fetch slim objects.
This add audit log entries when any group based setting of a user group
is updated. We store both the old and new values in extra_data, along
with the name of that setting. Entries populated during user group creation
are hardcoded to track "can_mention_group".
Potentially we can adjust "set_defaults_for_group_settings" so that it
populates realm audit logs with it, but that is out of scope for this change.
We use an atomic transaction so that the audit logs are committed
together with the updates.

This is mostly the same as tracking subgroup changes, except that now
modified_user_group is the subgroup.

It's worth noting that instead of adding another field to the
RealmAuditLog model, we store the modified subgroup ids in extra_data as
a JSON encoded dict with the key "subgroup_ids". We don't create audit
log entries for supergroup changes at this point.

Basically, I eliminate the use of select_all() in a query
that still makes a single round trip. We have good test
enforcement that Django never needs to lazily fetch
objects off the Stream object. (It used to be common
to fetch stream.realm a while back, but we upgraded
bulk_add_subscription, in particular, a while back.)
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")

Future commits will address the codepath for creating users.
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.
Updates find_proper_insertion_index to check for the inline image
classes as matching at least one of the classes in the element's
attrib["class"] so that cases where an inline preview image has
multiple classes, like YouTube video previews, will have the
correct insertion index.
Fixes#26186.
By relocating helper methods into a mixin class, we can be more flexible
with managing transactions in test cases, without always forcing the
django.test.TestCase behavior of always putting the test case into an
atomic transaction.
We include a check for side effects in ZulipTransactionTestCase. It only
checks for the set of row ids in all tables before and after each test.
It is not a comprehensive check for side effects, but should be
sufficient for the basics without much performance overhead.
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.
The 'get_gcm_alert' and 'get_apns_alert_subtitle' functions
don't include the case when the trigger is
'NotificationTriggers.FOLLOWED_TOPIC_WILDCARD_MENTION'.
This commit updates the functions to include
'NotificationTriggers.FOLLOWED_TOPIC_WILDCARD_MENTION'.
This commit fixes the incorrect calculation of the
'senders' list.
The effect of 'followed_topic_wildcard_mention'
wasn't considered earlier.
The bug was introduced in b052c8980e.
This commit uses 'NotificationTriggers' class attributes
instead of directly using loose strings.
This should have been ideally included in the commit
c3319a5231.

We now upstream the conversion of legacy tuples
into the callers of do_events_register. For the
codepath that builds the home view, this allows
for cleaner code in the caller. For the /register
endpoint, we have to do the conversion, but that
isn't super ugly, as that's an appropriate place
to deal with legacy formats and clean them up.
We do have to have do_events_register downgrade
the format back to tuples to pass them into
request_event_queue, because I don't want to
change any serialization formats. The conversion
is quite simple, and it has test coverage.
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.
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.
Subsequent commits will add "on_delete=models.RESTRICT"
relationships, which will result in the AlertWord
objects being deleted after Realm has been deleted from
the database.
In order to handle this, we update realm_alert_words_cache_key,
realm_alert_words_automaton_cache_key, and flush_realm_alert_words
functions 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 these functions and there
is no need of the complete realm object.

only realm_id is used by this function and there is no
need of the complete realm object.
Subsequent commits will add "on_delete=models.RESTRICT"

In order to handle this, we update bot_dicts_in_realm_cache_key

no need of the complete realm object.
Make the import of `Realm`, `Stream` and `UserGroup` objects be
done in single transaction, to make the import process in general
more atomic.
This also removes the need to temporarily unset the Stream references
on the Realm object. Since Django creates foreign key constraints
with `DEFERRABLE INITIALLY DEFERRED`, an insertion of a Realm row can
reference not-yet-existing Stream rows as long as the row is created
before the transaction commits.

This commit adds default_group_name field to GroupPermissionSetting
type which will be used to store the name of the default group for
that setting which would in most cases be one of the role-based
system groups. This will be helpful when we would have multiple
settings and we would need to set the defaults while creating
realm and streams.
For tests that use the dev server, like test-api, test-js-with-puppeteer,
we don't have the consumers for the queues. As they eventually timeout,
we get unnecessary error messages. This adds a new flag, disable_timeout,
to disable this behavior for the test cases.
The `tabbed_instructions` widget used for both language toggles in our

This is primarily to prevent impersonation, such as `zulipteam`. We

9d97af6ebb addressed the one major source of inconsistent data which
would be solved by simply re-attempting the ScheduledEmail row. Every
other instance that we have seen since then has been a corrupt or
modified database in some way, which does not self-resolve. This
results in an endless stream of emails to the administrator, and no
forward progress.
Drop this to a warning, and make it remove the offending row. This
ensures we make forward progress.

Failing to remove all of the rules which were added causes action at a

Note that we use the DjangoJSONEncoder so that we have builtin support
for parsing Decimal and datetime.
During this intermediate state, the migration that creates
extra_data_json field has been run. We prepare for running the backfilling
migration that populates extra_data_json from extra_data.
This change implements double-write, which is important to keep the
state of extra data consistent. For most extra_data usage, this is
handled by the overriden `save` method on `AbstractRealmAuditLog`, where
we either generates extra_data_json using orjson.loads or
ast.literal_eval.
While backfilling ensures that old realm audit log entries have
extra_data_json populated, double-write ensures that any new entries
generated will also have extra_data_json set. So that we can then safely
rename extra_data_json to extra_data while ensuring the non-nullable
invariant.
For completeness, we additionally set RealmAuditLog.NEW_VALUE for
the USER_FULL_NAME_CHANGED event. This cannot be handled with the
overridden `save`.
This addresses: https://github.com/zulip/zulip/pull/23116#discussion_r1040277795
Note that extra_data_json at this point is not used yet. So the test
cases do not need to switch to testing extra_data_json. This is later
done after we rename extra_data_json to extra_data.
Double-write for the remote server audit logs is special, because we only
get the dumped bytes from an external source. Luckily, none of the
payload carries extra_data that is not generated using orjson.dumps for
audit logs of event types in SYNC_BILLING_EVENTS. This can be verified
by looking at:
`git grep -A 6 -E "event_type=.*(USER_CREATED|USER_ACTIVATED|USER_DEACTIVATED|USER_REACTIVATED|USER_ROLE_CHANGED|REALM_DEACTIVATED|REALM_REACTIVATED)"`
Therefore, we just need to populate extra_data_json doing an
orjson.loads call after a None-check.

This commit removes realm_community_topic_editing_limit_seconds

constant since it is no longer used.
This prevents `get_user_profile_by_api_key` from doing a sequential
scan.
Doing this requires moving the generation of initial api_key values
into the column definition, so that even bare calls to
`UserProfile.objects.create` (e.g. from tests) call appropriately
generate a random initial value.
Deleting a message can race with sending a push notification for it.
b47535d8bb handled the case where the Message row has gone away --
but in such cases, it is also possible for `access_message` to
succeed, but for the save of `user_message.flags` to fail, because the
UserMessage row has been deleted by then.
Take a lock on the Message row over the accesses of, and updates to,
the relevant UserMessage row. This guarantees that the
message's (non-)existence is consistent across that transaction.
Partial fix for #16502.

Backfill subscription realm audit log SUBSCRIPTION_CREATED events for
users which are currently subscribed but don't have any subscription
events, presumably due to some historical bug. This is important
because those rows are necessary when reactivating a user who is
currently soft-deactivated.
For each stream, we find the subscribed users who have no
subscription-related realm audit log entries, and create a
`backfill=True` subscription audit log entry which is the latest it
could have been, based on UserMessage rows. We then optionally insert
a `DEACTIVATION` if the current subscription is not active.
We were missing a few checks for raw_unread_msgs being present before
trying to parse and update it.
The test only covers 2/3 of the cases, but I wasn't convinced it was
worth adding another test just for the corner case of removing a
message flag; this seems fairly unlikely to regress.
Previously, it seemed possible for the scheduled messages API to try
to send infinite copies of a message if we had the very poor luck of a
persistent failure happening after a message was sent.
The failure_message field supports being able to display what happened
in the scheduled messages modal, though that's not exposed to the API
yet.
The comment was outdated, currently we import UserProfiles before
realm_tables - because some models in realm_tables have a dependency on
UserProfile.
Also makes sense to elaborate a bit more in the comment that it's just
an outline of the ordering, not an exhaustive list.

We add Attachment.scheduled_messages relation to track ScheduledMessages
which reference the attachment.
The import bits can be done after merging this, by updating #25345.
Because education organizations and users have slightly specialized

demo organization owner because the 30 day deletion text is only
definitely accurate when the organization is created.

Updates the objects in the API for scheduled messages so that those
for stream messages return the `to` property as an integer since it

Also makes small update so that web app scheduled messages overlay
has the correct stream ID.
This commit places the email CSS into the `style` tag located in the

In #23380 we want to change all ocurrences of `uri` to `url`. This
commit changes the ocurrences of `uri` appeared in files related to
email, including templates (`.html`, `.txt`) and backend (`.py`)
codes.
In `email.md`, `base_images_uri` is changed to `images_base_url` -
the words `base` and `images` are swapped and plural form is added
for `image`. This is becasue the former is not found anywhere in
the codebase while the later appears a lot. To reduce confusion,
this doccumentation changed accordingly.
This also removes the error in one of these functions that was using a
different constant instead of
PRESENCE_LEGACY_EVENT_OFFSET_FOR_ACTIVITY_SECONDS.
This implements the core of the rewrite described in:
For the backend data model for UserPresence to one that supports much
more efficient queries and is more correct around handling of multiple
clients. The main loss of functionality is that we no longer track
which Client sent presence data (so we will no longer be able to say
using UserPresence "the user was last online on their desktop 15
minutes ago, but was online with their phone 3 minutes ago"). If we
consider that information important for the occasional investigation
query, we have can construct that answer data via UserActivity
already. It's not worth making Presence much more expensive/complex
to support it.
For slim_presence clients, this sends the same data format we sent
before, albeit with less complexity involved in constructing it. Note
that we at present will always send both last_active_time and
last_connected_time; we may revisit that in the future.
This commit doesn't include the finalizing migration, which drops the
UserPresenceOld table.
The way to deploy is to start the backfill migration with the server
down and then start the server *without* the user_presence queue worker,
to let the migration finish without having new data interfering with it.
Once the migration is done, the queue worker can be started, leading to
the presence data catching up to the current state as the queue worker
goes over the queued up events and updating the UserPresence table.

In a previous commit, the frontend of the web app was updated for
URLs with `#narrow/dm/...` for direct messages (group and 1-on-1).
Updates the URLs generated for email notifications and outgoing
webhook notification messages to use the new `/dm/...` format.
Adds backend support for `dm-including` operator. This will
deprecate the `group-pm-with` operator, but we keep support
for backwards-compatibility.
For testing updates, because the messages returned by these
two operators are different, most of the tests for `group-pm-with`
remain unchanged, but added comments about deprecated state.
Also, cleans up remaining instance of "PM" in `narrow.py` to
be "DM".
The general API changelog and documentation updates will be done
in a final commit in the series of commits that adds support for
the various new direct message narrows.
Adds backend support for `dm` operator. This will deprecate the
`pm-with` operator, but we keep support for backwards-compatibility.
For testing updates, updates the existing tests for `pm-with` to
use `dm`, and adds one basic test for `pm-with` in the `add_term`
tests as the two operators refer to the same `by_*` method.
The general API changelog and documentation updates will be done

the various new direct message narrows.
Adds backend support for `is` operator with the `dm` operand. This
will deprecate the `is` operator with the `private` operand, but we
keep support for backwards-compatibility.
Note that there is some clean up of references to private messages
in the updated backend test. In commit 43ec7ed, the documentation
for `build_narrow_filter` wasn't updated for the rename of
`BuildNarrowFilterTest` to `NarrowLibraryTest`, so that's also
corrected in these changes.
The general API changelog and documentation updates will be done

This swaps out url_format_string from all of our APIs and replaces it
with url_template. Note that the documentation changes in the following
commits will be squashed with this commit.
We change the "url_format" key to "url_template" for the
realm_linkifiers events in event_schema, along with updating
LinkifierDict. "url_template" is the name chosen to normalize
mixed usages of "url_format_string" and "url_format" throughout
the backend.
The markdown processor is updated to stop handling the format string
interpolation and delegate the task template expansion to the uri_template
library instead.
This change affects many test cases. We mostly just replace "%(name)s"
with "{name}", "url_format_string" with "url_template" to make sure that
they still pass. There are some test cases dedicated for testing "%"
escaping, which aren't relevant anymore and are subject to removal.
But for now we keep most of them as-is, and make sure that "%" is always
escaped since we do not use it for variable substitution any more.
Since url_format_string is not populated anymore, a migration is created
to remove this field entirely, and make url_template non-nullable since
we will always populate it. Note that it is possible to have
url_template being null after migration 0422 and before 0424, but
in practice, url_template will not be None after backfilling and the
backend now is always setting url_template.
With the removal of url_format_string, RealmFilter model will now be cleaned
with URL template checks, and the old checks for escapes are removed.
We also modified RealmFilter.clean to skip the validation when the
url_template is invalid. This avoids raising mulitple ValidationError's
when calling full_clean on a linkifier. But we might eventually want to
have a more centric approach to data validation instead of having
the same validation in both the clean method and the validator.

So far, we've used the BitField .authentication_methods on Realm
