This commits fixes the code which checks group mention permission
to handle anonymous user groups correctly. Basically we were
not checking whether the UserGroup is linked to a NamedUserGroup
and directly accessing named_user_group which results in an
error.
We also update the error messages to include the group name
which has permission to mention the groups since now there
might be a comnbination of groups and users who has permission
to mention the group.
This commit also adds tests to check sending and editing messages
when can_mention_group is set to a anonymous user group.
Earlier, we were using 'send_event' & 'queue_json_publish' in
'do_send_messages' which can lead to a situation where we enqueue
events but the transaction fails at a later stage.
Events should not be sent until we know we're not rolling back.
This commit renames are_both_setting_values_equal function
to are_both_group_setting_values_equal to make it clear
that this function is used to compare value of group
settings.
This commit moves validate_group_setting_value_change,
are_both_setting_values_equal and parse_group_setting_value
functions, which are used for updating the group settings, to
"zerver.lib.user_groups" as these functions will also be used for
group based realm and stream settings and "zerver.lib.user_groups"
file seems a better place to place such functions which are used
at multiple places.
For same reasons, we also move GroupSettingChangeRequest dataclass
to "zerver.lib.user_groups" file.
If an invalid timezone (such as +32h) was provided, the
timestamp.astimezone call would throw an exception, causing the
message send to fail. Replace that with a user-facing error.
Fixes#19658.
This is a follow-up to #29425. It assigns creator to three streams
that are used in tests and another two that aren't. For tests,
we assign a guest, an admin and an owner as creator.
To help users focus on the onboarding experience, we no longer
send the introductory "Zulip updates" message as a part of
onboarding.
Now, we send the introductory message just before the first
update message.
Fixes#30053.
This commit adds support to pass object containing both old and new
values of the can_mention_group setting, as well as detailed API
documentation for this part of the API system.

When importing a Stream, UserProfiles don't yet exist. so trying to
import stream.creator fails with something like:
```
psycopg2.errors.ForeignKeyViolation: insert or update on table
"zerver_stream" violates foreign key constraint
"zerver_stream_creator_id_65aeba7e_fk_zerver_userprofile_id"
DETAIL: Key (creator_id)=(5) is not present in table "zerver_userprofile".
```
In 'send_initial_realm_messages', the topics names were not
being translated properly as they were computed outside the
with `override_language` block.
Now, we use 'send_initial_realm_messages' inside a with
'override_language' block in the caller. This fixes the bug.
Note: We are using 'override_language' block in the caller
and not within the function as it helps to avoid indenting
everything inside the function.
The query to fetch one of the greetings message based on
content wasn't taking translation into account that would
result in a bug in realms using non-english language.
This commit updates the query to fix the bug.
- Tighten up the content.
- Use pretty quotes.
- Reorder "experiments" topic to appear after "start a conversation"
in Inbox.
- Drop reference to messages being starred (not implemented yet).
Instead of applying 'remove_single_newlines()' to individual
contents when declared, we use it once while prepping up
message in 'internal_prep_stream_message_by_name'.
Just for the code to be less finnicky.
The function is used for any type of onboarding step
i.e. not limited to Hotspot.
This commit updates the function and variables name
to reflect the above mentioned behaviour.
Mark the channel name of the initial channel created during
realm creation for translation.
It doesn't mark the topic names and description for translation
because we are planning to remove these topics and update the
description as a part of improving the onboarding experience.
We no longer create the 'core team' private channel when
a realm is created.
Earlier, "New user announcements" channel was set to the
"core team" channel. Now it is disabled by default.
populate_db still creates the 'core team' channel to
represent a private channel.
This commit updates access_user_group_for_setting
to support setting anonymous user groups for
different settings.
There are some lines without coverage as of this
commit, but the next few commits would add tests
covering those.
This commit fixes the queries to get members and subgroups for
user group objects returned by user_groups_in_realm_serialized
to not include the UserGroup objects which are not linked to a
NamedUserGroup object, since the function only returns data for
NamedUserGroup objects.
The naming `uri` is deprecated while `url` should be used in order to
satisfy URL standards. For this reason, four endpoints are affected:
* The response content of three endpoints `/server_settings`,
`/register` and `/realm` that contain a field `realm_uri` is
changed to `realm_url`.
* In one of the common fields for all mobile push notifications payloads,
`realm_url` field is now added as an alias to `realm_uri`.
For backwards compatibility, we keep the field `realm_uri` and add
an alias `realm_url`.

When the export is NOT generated by another zulip server,
while importing:
* Set the 'zulip_update_announcements_level' to the latest level
as we don't want to send all the older update messages to them.
* Send a group DM to admins, suggesting them to configure the
stream in order to avoid missing future update messages.
Fixes#29041.
Earlier, we were creating RealmAuditLog with REALM_EXPORTED
event_type when export of public data took place via organization
settings panel.
We were not creating the audit log when the export was executed
via shell i.e './manage.py export'.
This commit creates the audit log in that case too. It will
help during import to distinguish readily between imports
from another Zulip server vs imports from another product.
In #23380, we are changing all occurrences of uri with url in order to
follow the latest URL standard. Previous PRs #25038 and #25045 has
replaced the occurences of uri that has no direct relation with realm.
This commit changes just the model property, which has no API
compatibility concerns.
Also create dedicated channels and topics sections in sidebar.
Makes 'start a new topic', a section in introduction to topics
page.

Updates the base hash for the streams setting overlay to be
"channels" instead of "streams".
Because there are Welcome Bot and Notification Bot messages that
would have been sent with the "/#streams" hash, we will need to
support parsing those overlay hashes as an alias for "/#channels"
permanently.

This fixes the annoying behaviour where a task title with a url in it,
for example, "Fix issue https://github/com/zulip/zulip/issues/1234"
would be wrongly split into a description at the `:` in the url.
The returns plugin hasn’t been updated for mypy ≥ 1.6. This
annotation is more limited in that it only supports a fixed number of

Creates an IncompatibleParametersError to be used in cases where
there are two (or more) optional parameters for an endpoint that
are incompatible with each other, e.g. there's a parameter for a
user name and a user ID but only one should be sent in the request
to identify the user.
Documents the error on the /api/rest-error-handling article.
Updates the PATCH users/me/subscriptions/muted_topics endpoint to
use this error when both the stream and stream_id parameters are
passed (note this endpoint is currently deprecated).
This commit removes name, description, is_system_group and
can_mention_group fields from UserGroup model and rename
them in NamedUserGroup model.
Fixes#29554.
This commit updates code to access name from named_user_group
field which points to the "NamedUserGroup" instead of directly
accessing name from "UserGroup", since name field will only
be present on NamedUserGroup objects in further commits.
This commit adds get_recursive_strict_subgroups function
which returns all the subgroups but not includes the user
group passed to the function.
We also update the test to check subgroups of named user
groups using the get_recursive_strict_subgroups function.
This is fine as we already test the get_recursive_subgroups
function.
Changes url from /help/all-messages to /help/combined-feed.
Also renames files "all-messages.md" and "go-to-all-messages.md"
to "combined-feed.md" and "go-to-combined-feed.md" respectively.
Fixes#27802.
Earlier, we didn't soft-reactivate users for group mentions
at all because it wasn't easy to calculate group size.
Now, we will soft reactivate if the user group mentions has
less than 12 members.
We don't reactivate all users because a user group can have a
very large size, which can lead to large backlogs in the
deferred-work queue.
Fixes part of #27586.
This commit updates the code in 'handle_push_notifications'
to use a common lib function 'get_mentioned_user_group'.
The code logically does the same thing in both the places,
hence the change.
Earlier, in 'get_mentioned_user_group_name()' we were using
'get_user_group_direct_member_ids' function which just checks
the number of direct members and not the recursive membership
of the group.
We should instead use 'get_user_group_member_ids' to calculate
the correct members count of the user group.
Factor out the repeated pattern of taking a lock, or immediately
aborting with a message if it cannot be acquired. The exit code in
that situation is changed to be exit code 1, rather than the successful
0; we are likely missing new work since that process started.
We move the lockfiles to a common directory under `/srv/zulip-locks`
rather than muddy up `/home/zulip/deployments`.

as that will be updated as part of the help center changes for

plain text version of the email.
Updates the generated stream/channel url to use stream_narrow_url
in preparation for updating stream narrow urls for the rename.
Part of stream to channel rename project.
Generally updates variables that appear in translated strings that use
"stream" to instead use "channel".
Two exceptions are ErrorCode.STREAM_DOES_NOT_EXIST JsonableErrors as
changing the variable would also change the fields returned by these
errors to clients.
Changes to context variables in emails and variables in onboarding
welcome bot messages are addressed in separate commits.
Part of stream to channel rename project.
Adds nullable creator field, containing a reference to the user who
created the stream. When creating a stream, acting user is set as
the creator of the stream. Since API calls to create streams always
have an acting user, this field should always be set when streams
are created using the API.
Because streams can be created with no acting user, this field is
nullable. We try to backfill existing streams using RealmAuditLog table,
but not all streams are guaranteed to have a recorded create log. Thus
this new field is left null when it cannot be backfilled. We also set
this field to null when the creator user is deleted.
Fixes#28403
Uses redis to remember the last time push notifications were experienced
working. This needs to work across processes, so can't be done just in
memory.
As this is transient data that's fairly harmless to lose and thus
doesn't require the persistence benefits of the database, and we're
keeping a single "row", so don't need an entire new db table, we settle
on using redis instead of postgres. This is also consistent with how we
store other kinds of such transient data.
Earlier a extra audit log entry of type
USER_GROUP_GROUP_BASED_SETTING_CHANGED was made when a new user
group is created. This commit updates the code to not create
that audit log entry.
There is no need to create these entry as we would still
have the required data from the "OLD_VALUE" field in the
audit log entry created when changing the setting and this
also makes it consistent with the entries created for
other operations like stream creation.
This timeout strategy using asynchronous exceptions has a number of
safety caveats (read the docstring!!) and should only be used in very
specific circumstances.

soupsieve is a heavy-weight dependency, and Tornado pulls it in by way

9a682fb20a started performing message fetching in a read-only
transaction. However, our use of `get_or_create_huddle` can violate
the read-only promise, and result in a user-facing 500.
In the cases where we're attempting to narrow to a huddle that does
not exist, this is equivalent to a false condition; catch those,
without making the huddle row, and insert a false.
For simiplicty's sake, we can avoid trying to do cache invalidation in
the variety of events that can cause the seat count to change - since
having an up to 1 day delay between users being added and the upload
limit going up is quite reasonable.
Because loading boto3 is so slow, this saves a significant amount of
time (0.3s or so) in process startup on servers which are not using
the S3 file storage backend.
Uptil now, users could add tasks to a todo widget only after creating
it through the `/todo` command in the compose box.
Users can now add an initial list of tasks using the `/todo` command,
with each task on a new line in the compose box, where the 1st `:`
would separate a task from its (optional) description. Example:
`/todo\nTask1:description1\nTask2 without description`.
Fixes part of #20213.
Users can now name task lists by providing the task list title in the
`/todo` command on the same line. Example: `/todo School Work`. If no
title is provided by the user, "Task list" (which is also the
placeholder) is used as default.
The author of a task list can later edit / update the task list title
in the todo widget, just like the question in the poll widget.
Fixes part of #20213.
Uptil now, if the user did not specify a poll question, but included
options when using the `/poll` command, the 1st option wrongly
became the poll question.
Now on leaving the poll question space blank, the next line will not be
confused for it, and the poll widget will have an input for adding a
question.

f92d43c690 added uses of `@overload` to probide multiple type
signatures for `access_message`, based on the `get_user_message`
parameter. Unfortunately, mypy does not check the function body
against overload signatures, so it allows type errors to go
undetected.
Replace the overloads with two functions, for one of which also
returns the usermessage. The third form, of only returning if the
usermessage exists, is not in a high-enough performance endpoint that
a third form is worth maintaining; it uses the usermessage form.
The IntegrityError shows up in the database logs, which looks
unnecessarily concerning. Use `ON CONFLICT IGNORE` to mark this as
expected, especially since the return value is never used.
This commit adds a 'skip-delay' option to the
'send_zulip_update_announcements' management command.
It will be useful for self-hosted servers after 9.0 upgrade to
avoid the 24 hour delay to receive update messages after group
DM is sent to the admins.
One can run the management command with the --skip-delay flag
to immediately send the update messages.
When an organization (without open ability for anyone to join) invites a
guest user, the invitation prompts allows them to choose whether the
guest should be added to default streams or not. This is useful, because
since we don't have per-role default streams configs, they may want
default streams to be for full Members.
SCIM provisioning doesn't have this control, since a newly provisioned
user gets created via a direct do_create_user call, thus adding them to
the organization's default streams, with no workaround possible aside of
just getting rid of default streams in the organization.
To make provisioning guests in such an organization usable, we add a
simple config option to create them with no streams. It's configured by
adding
```
"create_guests_without_streams": True
```
to the config dict in settings.SCIM_CONFIG.
Creating a bot with a name that is already in use
will raise an error. However, by deactivating
the existing bot, creating a new bot with the
same name, and then reactivating the original bot,
it is possible to have multiple bots with the same name.
To fix this, we check if the bot name is already
in use in the active bots list. If it is,
an error will be raised, prompting either the
name of the existing bot to be changed or
the bot to be deactivated.

Adds "channel" to the `stream_wildcards` frozenset for stream
wildcard notifications on the backend/server.
Updates frontend/web-app to handle "channel" as the other stream
wildcards are handled in the typeahead and composebox modules.

"channel" as a wildcard mention. But does not change any of the

This is a prep commit to add a 'recipient_users' parameter to
the 'internal_send_huddle_message' function.
'emails' is no longer a required parameter. We can use either
of the 'emails' or 'recipient_users' parameter. 'emails' is
eventually used to fetch 'recipient_users', so if the
'recipient_users' is already available we should use that to
skip database query.
For organizations with "Zulip update announcements" stream set
to a default value, we wait for one day after sending group
DM to admins to allow them to change the stream from it's
default value if they wish to.
This prep commit refactors the function
'is_group_direct_message_sent_to_admins_atleast_one_week_ago' to
'is_group_direct_message_sent_to_admins_within_days' allowing us
to use a flexible timeframe instead of hardcoded 1 week.
We will reuse this function as a part of determinig whether
group DM to admins was sent within 1 day.
Previously, users were allowed to signup or change their names to
those which already existed in the realm.
This commit adds an Organization Permission, that shall enforce
users to use unique names while signing up or changing their
names. If a same or normalized full name is found in realm,
then a validation error is thrown.
Fixes#7830.
For multiline strings in triple quotes, a '\n' is included
at the end of each line.
Earlier, to skip '\n' we used to add an escape character '\'
at the end of each line.
This commit adds a function to avoid manually adding '\'.
As a part of the zulip news feature, we send an initial
group DM to admins suggesting them to update or set
the 'zulip_update_announcements_stream'.
This commit updates those messages to make it better.
As noted in the docstring for `bulk_insert_ums`, this is at least one
order of magnitude faster than using `bulk_create`. This also
includes a `ON CONFLICT DO NOTHING` which allows multiple
soft-reactivations to run at once without failing. We also adjust the
update of `last_active_message_id` to be safe against races.
Rather than use a bulk insert via Django, use the faster
`bulk_insert_all_ums` that we already have. This also adds a `ON
CONFLICT` clause, to make the insert resilient to race conditions.
There are currently two callsites, with different desired `ON
CONFLICT` behaviours:
- For `notify_reaction_update`, if the `UserMessage` had already been
created, we would have done nothing to change it.
- For `do_update_message_flags`, we would have ensured a specific bit
was (un)set.
Extend `create_historical_user_messages` and `bulk_insert_all_ums` to
support `ON CONFLICT (...) UPDATE SET flags = ...`.
The bots do not exist in the user table to look up their active
status, and attempting to import them into the analytics table will
result in duplicate rows.
Replace the long string for organisations that have notification
body/content disabled (settings.PUSH_NOTIFICATION_REDACT_CONTENT
set to true) with "New message".
This allows more of the limited space on the mobile device screen to
be used for additional messages rather than this verbose content.
Fixes#29152
For the common case of not needing to reference the UserMessage row
later, and for being a stream without private history, the UserMessage
row is irrelevant. Convert `has_user_message` to a thunk, and defer
loading it unless necessary.
Replaced HUDDLE attribute with DIRECT_MESSAGE_GROUP using VS Code search,

This commit adds a management command that will run regularly
as a cron job to send zulip updates to realms based on their
current and latest zulip_update_announcements_level.
For realms with:
* level = None: Send a group DM to admins notifying them about
this new feature & suggestion to set the stream accordingly.
* level = 0:
* If stream is still not configured, wait for a week
before setting their level to latest level. They will
miss updates until their configure the stream.
* If stream is configured, send updates.
* level > 0: Send one message/update per level & increase
the level by 1 till the latest level.

Replace a separate call to subprocess, starting `node` from scratch,
with an optional standalone node Express service which performs the
rendering. In benchmarking, this reduces the overhead of a KaTeX call
from 120ms to 2.8ms. This is notable because enough calls to KaTeX in
a single message would previously time out the whole message
rendering.
The service is optional because he majority of deployments do not use
enough LaTeX to merit the additional memory usage (60Mb).
Fixes: #17425.
Just shows a config error page if the bouncer is not enabled. Uses a new
endpoint for this so that it can work nicely for both browser and
desktop app clients.
It's necessary, because the desktop app expects to get a json response
with either an error or billing_access_url to redirect to. Showing a
nice config error page can't be done via the json error mechanism, so
instead we just serve a redirect to the new error page, which the app
will open in the browser in a new window or tab.
Only affects zulipchat, by being based on the BILLING_ENABLED setting.
The restricted backends in this commit are
- AzureAD - restricted to Standard plan
- SAML - restricted to Plus plan, although it was already practically
restricted due to requiring server-side configuration to be done by us
This restriction is placed upon **enabling** a backend - so
organizations that already have a backend enabled, will continue to be
able to use it. This allows us to make exceptions and enable a backend
for an org manually via the shell, and to grandfather organizations into
keeping the backend they have been relying on.
Adds a re-usable lockfile_nonblocking helper to context_managers.
Relying on naive `os.mkdir` is not enough especially now that the
successful operation of this command is necessary for push notifications
to work for many servers.
We can't use `lockfile` context manager from
`zerver.lib.context_managers`, because we want the custom behavior of
failing if the lock can't be acquired, instead of waiting.
That's because if an instance of this gets stuck, we don't want to start
queueing up more processes waiting forever whenever the cronjob runs
again and fail->exit is preferrable instead.
LoggingCountStats with a daily duration and that are directly stored
on the RealmCount table (not via aggregation in process_count_stat),
can be in a state, after the hourly cron job to update analytics
counts, where the logged value will be live-updated later, because
the end time for the stat is still in the future.
As these logging counts are designed to be used on the self-hosted
installation for either debugging or rate limiting, sending these
partial/incomplete counts to the bouncer has low value.

5c96f94206 mistakenly appended, rather than prepended, the edit to
the history. This caused AssertionErrors when attempting to view the
history of moved messages, which check that the `last_edit_time`
matches the timestamp of the first edit in the list.
Fix the ordering, and update the `edit_history` for messages that were
affected. We limit to only messages edited since the commit was
merged, since that helps bound the affected messages somewhat.
The widening of the time between when a process is marked for
reload (at Tornado startup) and when it sends reload events makes it
unlikely-to-impossible that a single `/` request will span both of
them, and thus hit the WebReloadClientError corner case.
Remove it, as it is not worth the complication. The bad behaviour it
is attempting to prevent (of a reload right after opening `/`) was
always still possible -- if the `/` request completed right before
Tornado restarted -- so it is not clear that it was ever worth the
complication.
Having a non-identity `cache_transformer` is no different from running
it on every row of the query_function. Simplify understanding of the
codepath used in caching by merging the pieces of code.
Rather than pass around a list of message objects in-memory, we
instead keep the same constructed QuerySet which includes the later
propagated messages (if any), and use that same query to pick out
affected Attachment objects, rather than limiting to the set of ids.
This is not necessarily a win -- the list of message-ids *may* be very
long, and thus the query may be more concise, easier to send to
PostgreSQL, and faster for PostgreSQL to parse. However, the list of
ids is almost certainly better-indexed.
After processing the move, the QuerySet must be re-defined as a search
of ids (and possibly a very long list of such), since there is no
other way which is guaranteed to correctly single out the moved
messages. At this point, it is mostly equivalent to the list of
Message objects, and certainly takes no less memory.
Rather than use `bulk_update()` to batch-move chunks of messages, use
a single SQL query to move the messages. This is much more efficient
for large topic moves. Since the `edit_history` field is not yet
JSON (see #26496) this requires that PostgreSQL cast the current data
into `jsonb`, append the new data (also cast to `jsonb`), and then
re-cast that as text.
For single-message moves, this _increases_ the SQL query count by one,
since we have to re-query for the updated data from the database after
the bulk update. However, this is overall still a performance
improvement, which improves to 2x or 3x for larger topic moves. Below
is a table of duration in seconds to run `do_update_message` to move a
topic to a new stream, based on messages in the topic, for before and
after this change:
| Topic size | Before | After |
| ---------- | -------- | ------- |
| 1 | 0.1036 | 0.0868 |
| 2 | 0.1108 | 0.0925 |
| 5 | 0.1139 | 0.0959 |
| 10 | 0.1218 | 0.0972 |
| 20 | 0.1310 | 0.1098 |
| 50 | 0.1759 | 0.1366 |
| 100 | 0.2307 | 0.1662 |
| 200 | 0.3880 | 0.2229 |
| 500 | 0.7676 | 0.4052 |
| 1000 | 1.3990 | 0.6848 |
| 2000 | 2.9706 | 1.3370 |
| 5000 | 7.5218 | 3.2882 |
| 10000 | 14.0272 | 5.4434 |
This applies access restrictions in SQL, so that individual messages
do not need to be walked one-by-one. It only functions for stream
messages.
Use of this method significantly speeds up checks if we moved "all
visible messages" in a topic, since we no longer need to walk every
remaining message in the old topic to determine that at least one was
visible to the user. Similarly, it significantly speeds up merging
into existing topics, since it no longer must walk every message in
the new topic to determine if the user could see at least one.
Finally, it unlocks the ability to bulk-update only messages the user
has access to, in a single query (see subsequent commit).
The problem was that earlier this was just an uncaught JsonableError,
leading to a full traceback getting spammed to the admins.
The prior commit introduced a clear .code for this error on the bouncer
side, meaning the self-hosted server can now detect that and handle it
nicely, by just logging.error about it and also take the opportunity to
adjust the realm.push_notifications_... flags.
- Renames "Bots and integrations" to "Bots overview" everywhere
(sidebar, page title, page URL).
- Adds a copy of /api/integrations-overview (symbolic link) as the
second page in the Bots & integrations section, titled
"Integrations overview".

The previous query suffered from bad corner cases when the user had
received a large number of direct messages but sent very few,
comparatively. This mean that the first half of the UNION would
retrieve a very large number of UserMessage rows, requiring fetching a
large number of Message rows, merely to throw them away upon
determining that the recipient was the current user.
Instead of merging two queries of "last 1k received" + "last 1k sent",
we instead make better use of the UserMessage rows to find "last 1k
sent or received." This may change the list of recipients, as large
disparities in sent/received messages may result in pushing the
most-recently-sent users off of the list. These are likely uncommon
edge cases, however -- and the disparity is the whole reason for the
performance problem.
This also provides more correct answers. In the case where a user's
1001'th message sent was to person A today, but my most recent message
received was from them yesterday, the previous plan would show the
message I received yesterday message-id as the max, and not the more
recent message I sent today.
While we could theoretically raise the `RECENT_CONVERSATIONS_LIMIT` to
more frequently match the same recipient list as previously, this
increases the cost of the most common cases unreasonably. With a
1000-message limit, the common cases are slightly faster, and the tail
latencies are very much improved; raising `RECENT_CONVERSATIONS_LIMIT`
would increase the result similarity to the old algorithm, at the cost
of the p50 and p75.
| | Old | New |
| ------ | ------- | ------- |
| Mean | 0.05287 | 0.02520 |
| p50 | 0.00695 | 0.00556 |
| p75 | 0.05592 | 0.03351 |
| p90 | 0.14645 | 0.08026 |
| p95 | 0.20181 | 0.10906 |
| p99 | 0.30691 | 0.16014 |
| p99.9 | 0.57894 | 0.19521 |
| max | 22.0610 | 0.22184 |
On the whole, however, the much more bounded worst case are worth the
small changes to the resultset.
This is preparatory work towards adding a Topic model.
We plan to use the local variable name as 'topic' for
the Topic model objects.
Currently, we use *topic as the local variable name for
topic names.
We rename local variables of the form *topic to *topic_name
so that we don't need to think about type collisions in
individual code paths where we might want to talk about both
Topic objects and strings for the topic name.
