A few major themes here:
- We remove short_name from UserProfile
and add the appropriate migration.
- We remove short_name from various
cache-related lists of fields.
- We allow import tools to continue to
write short_name to their export files,
and then we simply ignore the field
at import time.
- We change functions like do_create_user,
create_user_profile, etc.
- We keep short_name in the /json/bots
API. (It actually gets turned into
an email.)
- We don't modify our LDAP code much
here.
Log RealmAuditLog in do_set_realm_property and do_remove_realm_domain.
Tests for the changes are written in test_events because it will save
duplicate code for test_change_realm_property.
Added new Event Type in AbstractRealmAuditLog STREAM_CREATED.
Since we finally create streams in create_stream_if_needed function
in zerver/lib/streams.py so logged realm_audit there.
Passed acting_user when create_stream_if_needed or ensure_stream
function is called.
Added tests in test_audit_log.
This fixes our triggering a RabbitMQ event to send a push notification
to remove the empty set of push notifications, resulting from not
using the correct data structure to determine which message IDs to look at.
This was causing a lot of visible exceptions when running
the `test_messages.py` test suite.
For users who are unsubscribed from the new stream but are in
the old stream, we delete the UserMessage.
We send the delete_message event only to guest users,
who have completely lost asses to the moved messages, for other
users we send the normal update_message event which moves
the messages to the new unsubed stream which
otherwise would look broken to the
user without reloading to the webpage.
We remove support for the old clients which required an event for
each message to clear notification.
This is justified since it has been around 1.5 years since we started
supporting the bulk operation (and so essentially nobody is using a
mobile app version so old that it doesn't support the batched
approach) and the unbatched approach has a maintenance and reliability
cost.
This commit removes bugdown alias and do proper imports from markdown
module. Also remove bugdown word and replace it with markdown in
comments.
This commit is part of series of commits aimed at renaming bugdown to
markdown.
There is still some miscellaneous cleanup that
has to happen for things like analytics queries
and dead code in node tests, but this should
remove the main use of pointers in the backend.
(We will also still need to drop the DB field.)
This commit is first of few commita which aim to change all the
bugdown references to markdown. This commits rename the files,
file path mentions and change the imports.
Variables and other references to bugdown will be renamed in susequent
commits.
We send user_id of the referrer instead of email in the invites dict.
Sending user_ids is more robust, as those are an immutable reference
to a user, rather than something that can change with time.
Updates to the webapp UI to display the inviters for more convenient
inspection will come in a future commit.
We send a remove mobile push notification to the users who were
no longer mentioned after the content of the message was edited.
This also corrects the notification count for the mobile apps
where a user was prior mentioned in a muted stream / topic and the
message was edited and the user is no longer mentioned now.
Hence, fixing the case where user has read all his unreads
but the notification badge on the app is still positive.
Fixes#15428.
do_clear_mobile_push_notifications_for_ids can now be used to
clear push_notification for multiple users at once. This method
loops over users, so no performance optimization is gained.
We've been seeing an exception in server_event_dispatch.js in
production where in large organizations, sometimes when a new user
joined, every other browser in the organization would throw an
exception processing some sort of realm_user/update event.
It turns out the cause was that when a user copies their profile from
an existing user account with a user-uploaded avatar, the code path we
reused to set the avatar properly send a realm_user/update event about
the avatar change -- for a user that hadn't been fully created and
certainly hadn't have the realm_user/add event sent for.
We fix this and add tests and comments to prevent it recurring.
(Removed an incorrect docstring while working on this).
This commit changes do_get_user_invites function to not return
multiuse invites to non-admin users. We should only return multiuse
invites to admins, as we only allow admins to create them.
Streams can have lots of subscribers, meaning that the archiving process
will be moving tons of UserMessages per message. For that reason, using
a smaller batch size for stream messages is justified.
Some personal messages need to be added in test_scrub_realm to have
coverage of do_delete_messages_by_sender after these changes.
Old: a validator returns None on success and returns an error string
on error.
New: a validator returns the validated value on success and raises
ValidationError on error.
This allows mypy to catch mismatches between the annotated type of a
REQ parameter and the type that the validator actually validates.

Two things were broken here:
* we were using name(s) instead of id(s)
* we were always sending lists that only
had one element
Now we just send "stream_id" instead of "subscriptions".
If anything, we should start sending a list of users
instead of a list of streams. For example, see
the code below:
if peer_user_ids:
for new_user_id in new_user_ids:
event = dict(type="subscription", op="peer_add",
stream_id=stream.id,
user_id=new_user_id)
send_event(realm, event, peer_user_ids)
Note that this only affects the webapp, as mobile/ZT
don't use this.
The loop I added here in 5b49839b08 was
ill-conceived. The critical issue was that despite its name,
do_clear_mobile_push_notifications_for_ids does not immediately clear
push notifications (Except in our test suite, where `send_event`
immediately calls into the queue worker code!).
Instead, it queues work to clear those push notifications. Which
means that the first user to declare bankruptcy with a large number of
unreads will fill the queue, and then this will just be an infinite
loop adding more work to the queue.
This adds a new client_capability that clients such as the mobile apps
can use to avoid unreasonable network bandwidth consumed sending
avatar URLs in organizations with 10,000s of users.
Clients don't strictly need this data, as they can always use the
/avatar/{user_id} endpoint to fetch the avatar if desired.
This will be more efficient especially for realms with
10,000+ users because the avatar URLs would increase the
payload size significantly and cost us more bandwidth.
Fixes#15287.
This commit adds backend support for setting message_retention_days
while creating streams and updating it for an existing stream. We only
allow organization owners to set/update it for a stream.
'message_retention_days' field for a stream existed previously also, but
there was no way to set it while creating streams or update it for an
exisiting streams using any endpoint.
Fixes#14498.
When a topic is moved to a different stream, the message may no
longer be reachable to guest user, if the user is not subscribed
to the new stream.
We used to send message update event to the client in these cases,
which seems to be confusing both to the client updating the message
and the server sending push_notifications for it.
Now, we delete the UserMessage entry for these messages for the
user and send a delete message event to the client; which makes
both push_notification and the event handling client think that
the message was deleted and hence no confusion in the code is
raised.
The most import change here is the one in maybe_send_to_registration
codepath, as the insufficient validation there could lead to fetching
an expired PreregistrationUser that was invited as an administrator
admin even years ago, leading to this registration ending up in the
new user being a realm administrator.
Combined with the buggy migration in
0198_preregistrationuser_invited_as.py, this led to users incorrectly
joining as organizations administrators by accident. But even without
that bug, this issue could have allowed a user who was invited as an
administrator but then had that invitation expire and then joined via
social authentication incorrectly join as an organization administrator.
The second change is in ConfirmationEmailWorker, where this wasn't a
security problem, but if the server was stopped for long enough, with
some invites to send out email for in the queue, then after starting it
up again, the queue worker would send out emails for invites that
had already expired.
This commit removes is_old_stream property from the stream objects
returned by the API. This property was unnecessary and is essentially
equivalent to 'stream_weekly_traffic != null'.
We compute sub.is_old_stream in stream_data.update_calculated_fields
in frontend code and it is used to check whether we have a non-null
stream_weekly_traffic or not.
Fixes#15181.
This likely fix a bug that can leak thousands of messages into the
invalid state where:
* user_message.flags.active_mobile_push_notification is True
* user_message.flags.read is True
which is intended to be impossible except during the transient process
between marking messages as read sending the "remove push
notifications" event.
The bug is that if a user who is declaring bankruptcy with 10,000s of
unreads ends up having the database query to mark all of those as read
take 60s, the Django/uwsgi request will time out and kill the process.
If the postgres transaction still completes, we'll end up with the
second half of this function never being run.
A safer ordering is to do the smaller queries first.
We do this in a loop for correctness in the unlikely event there are
more than 10,000 of these.
This is designed to have no user-facing change unless the client
declares bulk_message_deletion in its client_capabilities.
Clients that do so will receive a single bulk event for bulk deletions
of messages within a single conversation (topic or PM thread).
Backend implementation of #15285.
Whenever we use API queries to mark messages as read we now increment
two new LoggingCount stats, messages_read::hour and
messages_read_interactions::hour.
We add an early return in do_increment_logging_stat function if there
are no changes (increment is 0), as an optimization to avoid
unnecessary database queries.
We also log messages_read_interactions::hour Logging stat
as the number of API queries to mark messages as read.
We don't include tests for the case where do_update_pointer is called
because do_update_pointer will most likely be removed from the
codebase in the near future.
Use read-only types (List ↦ Sequence, Dict ↦ Mapping, Set ↦
AbstractSet) to guard against accidental mutation of the default
value.

There seems to have been a confusion between two different uses of the
word “optional”:
• An optional parameter may be omitted and replaced with a default
value.
• An Optional type has None as a possible value.
Sometimes an optional parameter has a default value of None, or None
is otherwise a meaningful value to provide, in which case it makes
sense for the optional parameter to have an Optional type. But in
other cases, optional parameters should not have Optional type. Fix
them.

This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.
The only clients that should use the typing
indicators endpoint are our internal clients,
and they should send a JSON-formatted list
of user_ids.
We now enforce this, which removes some
complexity surrounding legacy ways of sending
users, such as emails and comma-delimited
strings of user_ids.
There may be a very tiny number of mobile
clients that still use the old emails API.
This won't have any user-facing effect on
the mobile users themselves, but if you type
a message to your friend on an old mobile
app, the friend will no longer see typing
indicators.
Also, the mobile team may see some errors
in their Sentry logs from the server rejecting
posts from the old mobile clients.
The error messages we report here are a bit
more generic, since we now just use REQ
to do validation with this code:
validator=check_list(check_int)
This also allows us to remove a test hack
related to the API documentation. (We changed
the docs to reflect the modern API in an
earlier commit, but the tests couldn't be
fixed while we still had the more complex
semantics for the "to" parameter.)

Old topic of the msg edit event can be used to help the client
calculate useful information such as if a change
in current narrow is required.
This fixes our re narrow logic after a stream edit of a topic, with
no change in topic name itself, since the original topic was not
present in the event received and hence the `orig_topic` was
undefined in this case.
Option to disable breadcrumb messages were given in both message edit
form and topic edit stream popover.
User now has the option to select which stream to send the notification
of stream edit of a topic via checkboxes in the UI.
We pipe realm_id through functions where it is available,
this helps us avoid doing query for realm_id in loop when
multiple messages are being processed.
This reimplements our Zoom video call integration to use an OAuth
application. In addition to providing a cleaner setup experience,
especially on zulipchat.com where the server administrators can have
done the app registration already, it also fixes the limitation of the
previous integration that it could only have one call active at a time
when set up with typical Zoom API keys.

We change do_create_user and create_user to accept
role as a parameter instead of 'is_realm_admin' and 'is_guest'.
These changes are done to minimize data conversions between
role and boolean fields.
This commit changes the person dict in event sent by do_change_user_role
to send role instead of is_admin or is_guest.
This makes things much more straightforward for our upcoming primary
owners feature.
This commit changes do_change_user_role to support adding or removing
the realm owner status of user and sending an event.
We also extend the existing test for do_change_user_role to do a bit
more validation to confirm the audit log records all values of role.
The new realm_owner role is added as option for role field in
UserProfile model and is_realm_owner is added as property for the user
profile.
Aside from some basic tests validating the logic, this has no effect
as users cannot end up with set as realm owners.
If a user receives more than one invite to join a
realm, after that user registers, all the remaining
invitations should be revoked, preventing them to be
listed in active invitations on admin panel.
To do this, we added a new prereg_user status,
STATUS_REVOKED.
We also added a confirmation_link_expired_error page
in case the user tries click on a revoked invitaion.
This page has a link to login page.

This commit merges do_change_is_admin and do_change_is_guest to a
single function do_change_user_role which will be used for changing
role of users.
do_change_is_api_super_user is added as a separate function for
changing is_api_super_user field of UserProfile.
During events such as stream / topic name edit for a topic, we were
running queries to db in loop for each message for reactions,
submessages and realm_id. This commit reduces the queries to be
done only for realm_id, which is yet to be fixed.
This is accomplished by building messages with empty reactions
and submessages and then updating them in the messages using bulk
queries.
The `email` field for identifying the user being modified in these
events was not used by either the webapp or other official Zulip
clients. Instead, it was legacy data from before we switched years
ago to sending user_id fields as the correct way to uniquely identify
a user.
When a user changes its avatar image, the user's avatar in popovers
wasn't being correctly updated, because of browser caching of the
avatar image. We added a version on the request to get the image in
the same format we use elsewhere, so the browser knows when to use the
cached image or to make a new request to the server.
Edited by Tim to preserve/fix sort orders in some tests, and update
zulip_feature_level.
Fixes: #14290
We remove the `owner` field from `page_params/realm_bots`
and bot-related events.
In the recent commit 155f6da8ba
we added `owner_id`, which we now use everywhere we need
bot owners for.
We also bump the `API_FEATURE_LEVEL` to 5 here. We
had already documented this in the prior commit to
add `owner_id`.
Note that we don't have to worry about mobile/ZT clients
here--we only deal with bot data in the webapp.
For the below payloads we want `owner_id` instead
of `owner`, which we should deprecate. (The
`owner` field is actually an email, which is
not a stable key.)
page_params.realm_bots
realm_bot/add
realm_bot/update
IMPORTANT NOTE: Some of the data served in
these payloads is cached with the key
`bot_dicts_in_realm_cache_key`.
For page_params, we get the new field
via `get_owned_bot_dicts`.
For realm_bot/add, we modified
`created_bot_event`.
For realm_bot/update, we modified
`do_change_bot_owner`.
On the JS side, we no longer
look up the bot's owner directly in
`server_events_dispatch` when we get
a realm_bot/update event. Instead, we
delegate that job to `bot_data.js`.
I modified the tests accordingly.
When editing a message where we mention a usergroup, we would remove
the 'mentioned' flag from messages, resulting in the message being
hidden from your mentions in the UI. This was reported by Greg Price in
https://chat.zulip.org/#narrow/stream/9-issues/topic/missing.20mention.
We add the same code that we use in do_send_messages to calculate the
updated mentions_user_ids. We add some tests alongside other user group
mention tests in test_bugdown.
These changes should be included in bd9b74436c,
as it makes sure that Zulip limited plan realm won't be able to change the
`message_retention_days` setting.
Member of the org can able see list of invitations sent by him/her.

Fixes#14007.
Prior to this change, there were reports of 500s in
production due to `export.extra_data` being a
Nonetype. This was reproducible using the s3
backend in development when a row was created in
the `RealmAuditLog` table, but the export failed in
the `DeferredWorker`. This left an entry lying
about that was never updated with an `extra_data`
field.
To fix this, we catch any exceptions in the
`DeferredWorker`, and then update `extra_data` to
encode the failure. We also fix the fact that we
never updated the export UI table with pending exports.
These changes also negated the use for the somewhat
hacky `clear_success_banner` logic.
The logic in do_set_realm_property would previously "change" the email
addrssees of every user in the realm, even if they hadn't actually
changed.
We fix this by skipping the logic when it's unnecessary.
bulk_update is used to update the email of user_profile objects in
database when email_address_visibility is changed.
This helps resolve the problem of timeout errors in realms with large
number of users due to large number of database queries run in a
loop.
Since bulk_update doesn't flush caches, we need our own bit of code to
do that.
Fixes a part of #14600.
We add URLs to the `links_for_embed set`, only when
the `url_embed_preview_enabled` flag is turned on.
So, it is sufficient to check if `links_for_embed`
is not empty.
Previously, the message and event APIs represented the user differently
for the same reaction data. To make this more consistent, I added a
user_id field to the reaction dict for both messages and events. I
updated the front end to use the user_id field rather than the user
dict. Lastly, I updated front end and back end tests that used user
info.
I primarily tested this by running my local Zulip build and
adding/removing reactions from messages.

This commit reuses the existing infrastructure for moving a topic

another.
Split from the original full-feature commit so that we can merge just
the backend, which is finished, at this time.

The feature is incomplete, in that we don't have real-time update of
the frontend to handle the event, documentation, etc., but this commit

The distinction between ValueError and TypeError
is not useful in these functions:
- extract_stream_indicator
- extract_private_recipients (or its callees)
These are always invoked in views to validate
user input.
When we use REQ to wrap the validators, any
Exception gets turned into a JsonableError, so
the distinction is not important.
And if we don't use REQ to wrap the validators,
the errors aren't caught.
Now we just let these functions directly produce
the desired end result for both codepaths.
Also, we now flag the error strings for translation.
This improves the error handling for invalid values of the
propagate_mode parameter to our message editing endpoints.
Previously, invalid values would just work like change_one rather than
doing nothing.
We don't need `do_create_user` to send a partial
event here for bots. The only caller to `do_create_user`
that actually creates bots (apart from some tests that
just need data setup) is `add_bot_backend`, which
sends the more complete event including bot "extras"
like service info.
The modified event tests show the simplification
here (2 events instead of 3).
Also, the bot tests now use tuple unpacking, which
will force a ValueError if we duplicate events
again.
Using an Exists subquery to avoid scanning the entire Subscription
table seems to speed things up greatly.
Set up with:
./manage.py populate_db --extra_users 2000 --extra-streams 1000
Tested on my computer, the original function was taking ~1.2seconds,
the optimized version only ~0.05-0.06.
Likely fixes#13874; we can re-open if after production testing we
feel more work is warranted.
This extends our email address visibility settings to deny access to
user email addresses even to organization administrators.
At the moment, they can of course change the setting (which leaves an
audit trail), but in the future only organization owners will be able
to change that setting.
While we're at this, we rewrite the settings_data.js test to cover all
the cases in a more consistent way.
Fixes#14111.
We were using `code` to pass around messages.
The `code` field is designed to be a code, not
a human-readable message.
It's possible that we don't actually need two
flavors of messages for these type of validations,
but I didn't want to change that yet.
We **definitely** don't need to put two types of
message in the exception, so I fix that. Instead,
I just have the caller ask what level of detail
it needs.
I added a non-verbose message for the case of
system bots.
I removed the non-translated version of the message
for deactivated accounts, which didn't have test
coverage and is slightly more prone to leaking
email info that we don't want to leak.
In the prep commits leading up to this, we split
out two new helpers:
validate_email_is_valid
get_errors_for_new_emails
Now when we validate invites we use two separate
loops to filter our emails.
Note that the two extracted functions map to two
of the data structures that used to be handled
in a single loop, and now we break them out:
errors = validate_email_is_valid
skipped = get_errors_for_new_emails
The first loop checks that emails are even valid
to begin with.
The second loop finds out whether emails are already
in use.
The second loop takes advantage of this helper:
get_errors_for_new_emails
The second helper can query all potential new emails
with a single round trip to the database.
This reduces our query count.
We are trying to kill off `validate_email`, so
we no longer call it from these tests.
These tests are already kind of low-level in
nature, so testing the more specific helpers
here should be fine.
Note that we also make the third parameter
to `validate_email` non-optional in this commit,
to preserve 100% coverage. This is really just
refactoring noise--we will soon eliminate the
entire function, but I didn't want to do everything
in a huge commit.
This is a prep commit that will allow us
to more efficiently validate a bunch of
emails in the invite UI.
This commit does not yet change any
behavior or performance.
A secondary goal of this commit is to
prepare us to eliminate some hackiness
related to how we construct
`ValidationError` exceptions.
It preserves some quirks of the prior
implementation:
- the strings we decided to translate
here appear haphazard (and often
get ignored anyway)
- we use `msg` in most codepaths,
but use `code` for invites
Right now we never actually call this with
more than one email, but that will change
soon.
Note that part of the rationale for the inner
method here is to avoid a test coverage bug
with `continue` in loops.
This has two goals:
- sets up a future commit to bulk-validate
emails
- the extracted function is more simple,
since it just has errors, and no codes
or deactivated flags
This commit leaves us in a somewhat funny
intermediate state where we have
`action.validate_email` being a glorified
two-line function with strange parameters,
but subsequent commits will clean this up:
- we will eliminate validate_email
- we will move most of the guts of its
other callee to lib/email_validation.py
To be clear, the code is correct here, just
kinda in an ugly, temporarily-disorganized
intermediate state.
We now use the `get_realm_email_validator()`
helper to build an email validator outside
the loop of emails in our invite list.
This allows us to perform RealmDomain queries
only once per request, instead of once per
email.
Now called:
validate_email_not_already_in_realm
We have a separate validation function that
makes sure that the email fits into a realm's
domain scheme, and we want to avoid naming
confusion here.
Without the fix here, you will get an exception
similar to below if you try to invite one of the
cross realm bots. (The actual exception is
a bit different due to some rebasing on my branch.)
File "/home/zulipdev/zulip/zerver/lib/request.py", line 368, in _wrapped_view_func
return view_func(request, *args, **kwargs)
File "/home/zulipdev/zulip/zerver/views/invite.py", line 49, in invite_users_backend

TypeError: 'NoneType' object is not subscriptable
Obviously, you shouldn't try to invite a cross
realm bot to your realm, but we want a reasonable
error message.
RESOLUTION:
Populate the `code` parameter for `ValidationError`.
BACKGROUND:
Most callers to `validate_email_for_realm` simply catch
the `ValidationError` and then report a more generic error.
That's also what `do_invite_users` does, but it has the
somewhat convoluted codepath through `validate_email`
that triggers this code:
try:
validate_email_for_realm(user_profile.realm, email)
except ValidationError as error:
return None, (error.code), (error.params['deactivated'])
The way that we're using the `code` parameter for
`ValidationError` feels hacky to me. The intention
behind `code` is to provide a descriptive error to
calling code, and it's not intended for humans, and
it feels strange that we actually translate this in
other places. Here are the Django docs:
https://docs.djangoproject.com/en/3.0/ref/forms/validation/
And then here's an example of us actually translating
a code (not part of this commit, just providing context):
raise ValidationError(_('%s already has an account') %
(email,), code = _("Already has an account."),
params={'deactivated': False})
Those codes eventually get put into InvitationError, which
inherits from JsonableError, and we do actually display
these errors in the webapp:
if skipped and len(skipped) == len(invitee_emails):
# All e-mails were skipped, so we didn't actually invite anyone.
raise InvitationError(_("We weren't able to invite anyone."),
skipped, sent_invitations=False)
I will try to untangle this somewhat in upcoming commits.
/delete_topic endpoint could be used to request the deletion of a topic,
that would cause do_delete_messages to be called with an empty set in
these cases:
1. Requesting deletion of an empty stream.
2. Requesting deletion of a topic in a private stream with history not
public to subscribers, if the requesting admin doesn't have access to
any of the messages in that topic.
This function slims down the data that we get
from the database in order to create the
streams part of our client payload.
We also fix a typo.
We also clearly distinguish between queries
and lists here.
This new method prevents us from getting fat
objects from the database.
Instead, now we just get ids from the database
to build our subqueries.
Note that we could also technically eliminate
the `set(...)` wrappers in this code to have
Django make a subquery and save a round trip.
I am postponing that for another commit (since
it's still somewhat coupled to some other
complexity in `do_get_streams` that I am trying
to cut through, plus it's not the main point
of this commit.)
BEFORE:
# old, still in use for other codepaths
def get_stream_subscriptions_for_user(user_profile: UserProfile) -> QuerySet:
# TODO: Change return type to QuerySet[Subscription]
return Subscription.objects.filter(
user_profile=user_profile,
recipient__type=Recipient.STREAM,
)
user_subs = get_stream_subscriptions_for_user(user_profile).filter(
active=True,
).select_related('recipient')
recipient_check = Q(id__in=[sub.recipient.type_id for sub in user_subs])
AFTER:
# newly added
def get_subscribed_stream_ids_for_user(user_profile: UserProfile) -> QuerySet:
return Subscription.objects.filter(
user_profile_id=user_profile,
recipient__type=Recipient.STREAM,
active=True,
).values_list('recipient__type_id', flat=True)
subscribed_stream_ids = get_subscribed_stream_ids_for_user(user_profile)
recipient_check = Q(id__in=set(subscribed_stream_ids))
For historical reasons we were creating Recipient
objects at some point in the typing-notifications
codepath. Now we just work with UserProfiles.
This removes some queries, as indicated by
the change to `len(queries)` in a couple of the
tests.
The one subtle thing that changes here is huddles.
If user 10 sends a typing notification that they
are talking to users 20 and 30, there might not
actually be a huddle for users 10/20/30, but
we were actually creating huddles on the fly!
There is no need to create huddles just for
typing notifications, since we don't even
share huddle ids with our clients. The clients
just infer the huddles.
Some of the code that gets killed off here as
somewhat "collateral damage" is some
defensive code related to formerly supporting streams
in typing indicators. The support for streams
was killed off almost as soon as we released
the feature, and the codepath is pretty clearly
user-centric at this point.
I actually like this pattern:
def check_send_typing_notification(...):
typing_notification = check_typing_notification(...)
do_send_typing_notification(...)
It can help divide responsibilities nicely and make it easy
to write detailed unit tests against each of the two helpers.
Unfortunately, the good things didn't really happen here, and
instead we got the worst aspects of the pattern:
- The responsibilities for validation leaked into
the second function.
- Both functions were doing sane things individually
that became not-so-sane in the big picture (namely,
we ended up making Recipient objects for no reason,
but if you read each of the helpers, it was just one
step that seemed reasonable).
- Passing around dictionaries for results can be annoying.
Also, the pattern made a lot more sense when the validation
for typing was a lot more complicated. My prior commit makes
it so that we only ever deal with a list of user_ids.
Anyway, now I'm inlining it. :)
Subsequent commits will clean up the more substantive issue
here, which is that we are building Recipients for no reason.
This field wasn't accessed by any clients and was a less robust
version of the user_id field. Any client hoping to be interested in
who did message edits should be able to handle working with user IDs
rather than email addresses.
This is mostly refactoring, but we also prevent a new
type of value error (list of non-int-or-string). The
new test code helps enforce that.
Cleanup includes:
- Use early-exit for email case.
- Rename helpers to get_validate_*.
- Avoid clumsy rebuilding of lists in helpers.
- Avoid the confusing `recipient` name (which
can be confused with the model by the same
name).
- Just delegate duplicate-id/email-removal to
the helpers.
The cleaner structure allows us to elminate a couple
mypy workarounds.
Credits to @xpac1985 for reporting, debugging and proposing fix to the
issue. The proposed fix was modified slightly by @hackerkid to set the
correct value for max_invites and upload_quota_gb. Tests added by
@hackerkid.
Fixes#13974
We now validate streams with a separate
function from PM recipients.
It's confusing enough all the ways you can
encode a stream or encode the PM recipients,
but trying to do it all in one function was
hard to reason about and led to at least one
bug.
In particular, there was a bug where streams
with commas in them would get split. Now
we just don't ever split on commas inside
of `extract_stream_indicator`.
Fixes#13836
After removing internal_send_message() in a recent
commit, we now have only two callers for
extract_recipients, and they are both related
to our REQ mechanism that always passes strings
to converters. (If there are default values,
REQ does not call the converters.)
We therefore make two changes:
- use the more strict annotation of "str"
for the `s` parameter
- don't bother with the isinstance check
This index is intended to optimize the performance of the very
frequently run query of "what is the presence status of all users in a
realm?".
Main changes:
- add realm_id to UserPresence
- add index for realm_id
- backfill realm_id for old rows
- change all writes to UserPresence to include
realm_id
The index is of this form:
"zerver_userpresence_realm_id_5c4ef5a9" btree (realm_id)
We will create an index on (realm_id, timestamp) in a
future commit, but I think it's a bit faster if you do
the backfill before the index.
There's also a minor tweak to the populate_db script.
This is just a refactoring to the more modern API
for sending internal messages.
To make this work we now plumb the email_gateway
flag through `internal_send_stream_message` instead
of `internal_send_message`.
We also change `send_zulip` to have its callers
pass in a full UserProfile object (which one of
them already had).
We prefer this to internal_send_message().
We are trying to deprecate `internal_send_message`,
which has extra moving parts related to
`extract_recipients` and `Addressee.legacy_build`.
There are two chunks of code that I touch here
that look pretty similar, but I'm not quite
sure they're worth de-duplicating, since they
use different topics and different message
content.
Instead of having `notify_new_user` delegate
all the heavy lifting to `send_signup_message`,
we just rename `send_signup_message` to be
`notify_new_user` and remove the one-line
wrapper.
We remove a lot of obsolete complexity:
- `internal` was no longer ever set to True
by real code, so we kill it off as well
as well as killing off the internal_blurb code
and the now-obsolete test
- the `sender` parameter was actually an
email, not a UserProfile, but I think
that got past mypy due to the caller
passing in something from settings.py
- we were only passing in NOTIFICATION_BOT
for the sender, so we just hard code
that now
- we eliminate the verbose
`admin_realm_signup_notifications_stream`
parameter and just hard code it to
"signups"
- we weren't using the optional realm
parameter
There's also a long ugly comment in
`get_recipient_info` related to this code
that I amended for now.
We should try to take action in a subsequent
commit.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.
It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.
This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.
With many tweaks by tabbott to documentation under /help, etc.
Fixes#13616.
This flag affects page_params and the
payload you get back from POSTs to this
url:
users/me/presence
The flag does not yet affect the
presence events that get sent to a
client.
While the result of this change doesn't completely do what we need, it
does remove a huge amount of duplicated lists of fields. With a bit
more similar work, we should be able to eliminate a broad category of
potential bugs involving Stream and Subscription objects being
represented inconsistently in the API.
Work towards #13787.
This has the side of effect of making new fields we add to Stream be
automatically included, which will help maintain this code as we
upgrade it.
This commit adds is_web_public, history_public_to_subscribers, and
email_notifications fields to the dictionary.
This moves get_cross_realm_dicts (from zerver.lib.actions),
get_raw_user_data and get_custom_profile_field_values (from
zerver.lib.events) to zerver.lib.users.
This legacy cross-realm bot hasn't been used in several years, as far
as I know. If we wanted to re-introduce it, I'd want to implement it
as an embedded bot using those common APIs, rather than the totally
custom hacky code used for it that involves unnecessary queue workers
and similar details.
Fixes#13533.
Previously, if you tried to invite a user whose account had been
deactivated, we didn't provide a clear path forward for reactivating
the users, which was confusing.
We fix this by plumbing through to the frontend the information that
there is an existing user account with that email address in this
organization, but that it's deactivated. For administrators, we
provide a link for how to reactivate the user.
Fixes#8144.
This experimental setting disables sending private messages in Zulip
in a crude way (i.e. users get an error when they try to send one).
It makes no effort to adjust the UI to avoid advertising the idea of
sending private messages.
Fixes#6617.
We should take adventage of the recipient field being denormalized into
the Stream model. We don't need to make queries to figure out a stream's
recipient id, so we take advantage of that to eliminate some of
those redundant queries and simplify StreamRecipientMap.
For cross realm bots, explicitly set bot_owner_id
to None. This makes it clear that the cross realm
bots have no owner, whereas before it could be
misdiagnosed as the server forgetting to set the
field.
In 3892a8afd8, we restructured the
system for managing uploaded files to a much cleaner model where we
just do parsing inside bugdown.
That new model had potentially buggy handling of cases around both
relative URLs and URLS starting with `realm.host`.
We address this by further rewriting the handling of attachments to
avoid regular expressions entirely, instead relying on urllib for
parsing, and having bugdown output `path_id` values, so that there's
no need for any conversions between formats outside bugdowm.
The check_attachment_reference_change function for processing message
updates is significantly simplified in the process.
The new check on the hostname has the side effect of requiring us to
fix some previously weird/buggy test data.

Previously, these accesses used e.g. .select_related("realm"), which
was the only foreign key on the Stream model. Since the intent in
these code paths is to attach the related models for efficient access,
we should just do that for all related models, including Recipient.
With the recipient field being denormalized into the UserProfile and
Streams models, all current uses of get_stream_recipients can be done
more efficiently, by simply checking the .recipient_id attribute on the
appropriate objects.
With the recipient field being denormalized into the UserProfile and
Streams models, all current uses of bulk_get_recipients can be done more
efficient, by simply checking the .recipient_id attribute on the
appropriate objects.
The flow in recipient_for_user_profiles previously worked by doing
validation on UserProfile objects (returning a list of IDs), and then
using that data to look up the appropriate Recipient objects.
For the case of sending a private message to another user, the new
UserProfile.recipient column lets us avoid the query to the Recipient
table if we move the step of reducing down to user IDs to only occur
in the Huddle code path.
Previously, if the user had interacted with the Zulip mobile app in
the last ~140 seconds, it's likely the mobile app had sent presence
data to the Zulip server, which in turns means that the Zulip server
might not send that user mobile push notifications (or email
notifications) about new messages for the next few minutes.
The email notifications behavior is potentially desirable, but the
push notifications behavior is definitely not -- a private message
reply to something you sent 2 minutes ago is definitely something you
want a push notification for.
This commit partially addresses that issue, by ignoring presence data
from the ZulipMobile client when determining whether the user is
currently engaging with a Zulip client (essentially, we're only
considering desktop activity as something that predicts the user is
likely to see a desktop notification or is otherwise "online").
This removes the last of the messy use of regular expressions outside
bugdown to make decisions on whether a message contains an attachment
or not. Centralizing questions about links to be decided entirely
within bugdown (rather than doing ad-hoc secondary parsing elsewhere)
makes the system cleaner and more robust.
This commit wraps up the work to remove basic regex based parsing
of messages to handle attachment claiming/unclaiming. We now use
the more dependable Bugdown processor to find potential links and
only operate upon those links instead of parsing the full message
content again.
Previously, we would naively set has_attachment just by searching
the whole messages for strings like `/user_uploads/...`. We now
prevent running do_claim_attachments for messages that obviously
do not have an attachment in them that we previously ran.
For example: attachments in codeblocks or
attachments that otherwise do not match our link syntax.
The new implementation runs that check on only the urls that
bugdown determines should be rendered. We also refactor some
Attachment tests in test_messages to test this change.
The new method is:
1. Create a list of potential_attachment_urls in Bugdown while rendering.
2. Loop over this list in do_claim_attachments for the actual claiming.
For saving:
3. If we claimed an attachment, set message.has_attachment to True.
For updating:
3. If claimed_attachment != message.has_attachment: update has_attachment.
We do not modify the logic for 'unclaiming' attachments when editing.
Adds required API and front-end changes to modify and read the
wildcard_mentions_notify field in the Subscription model.
It includes front-end code to add the setting to the user's "manage
streams" page. This setting will be greyed out when a stream is muted.
The PR also includes back-end code to add the setting the initial state of
a subscription.
New automated tests were added for the API, events system and front-end.
In manual testing, we checked that modifying the setting in the front end
persisted the change in the Subscription model. We noticed the notifications
were not behaving exactly as expected in manual testing; see
https://github.com/zulip/zulip/issues/13073#issuecomment-560263081 .
Tweaked by tabbott to fix real-time synchronization issues.
Fixes: #13429.
This is adds foreign keys to the corresponding Recipient object in the
UserProfile on Stream tables, a denormalization intended to improve
performance as this is a common query.
In the migration for setting the field correctly for existing users,
we do a direct SQL query (because Django 1.11 doesn't provide any good
method for doing it properly in bulk using the ORM.).
A consequence of this change to the model is that a bit of code needs
to be added to the functions responsible for creating new users (to
set the field after the Recipient object gets created). Fortunately,
there's only a few code paths for doing that.
Also an adjustment is needed in the import system - this introduces a
circular relation between Recipient and UserProfile. The field cannot be
set until the Recipient objects have been created, but UserProfiles need
to be created before their corresponding Recipients. We deal with this
by first importing UserProfiles same way as before, but we leave the
personal_recipient field uninitialized. After creating the Recipient
objects, we call a function to set the field for all the imported users
in bulk.
A similar change is made for managing Stream objects.
This is a performance optimization, since we can avoid doing work
related to wildcard mentions in the common case that the message can't
have any. We also add a unit test for adding wildcard mentions in a
message edit.
This change makes it possible for users to control the notification
settings for wildcard mentions as a separate control from PMs and
direct @-mentions.
This includes adding a new endpoint to the push notification bouncer
interface, and code to call it appropriately after resetting a user's
personal API key.
When we add support for a user having multiple API keys, we may need
to add an additional key here to support removing keys associated with
just one client.
The function only used the user's realm anyway, so this is a cleaner
API.
This should also make it more convenient to permanently delete
messages manually, since one doesn't have to fetch a random user in
the realm in order to delete a message using the management shell.
No functional change.
Rather than subtracting sets in multiple places, it's simpler/cleaner
to just check which users are in the set when processing them.
This refactoring be helpful when we extend the get_recipient_info
logic to handle wildcard mentions as well.
Previously, we were using user_profile.email rather than
user_profile.delivery_email in all calculations involving Gravatar
URLs, which meant that all organizations with the new
EMAIL_ADDRESS_VISIBILITY_ADMINS setting enabled had useless gravatars
not based on the `user15@host.domain` type fake email addresses we
generate for the API to refer to users.
The fix is to convert these calculations to use the user's
delivery_email. Some refactoring is required to ensure the data is
passed through to the parts of the codebase that do the check;
fortunately, our automated tests of schemas are effective in verifying
that the new `sender_delivery_email` field isn't visible to the API.
Fixes#13369.
This is a follow-up to b69213808a.
We now actually send messages from the notification_bot, which
is the real usecase for this code.
Also, this cleans up the code and removes needless asserts like
`assertNotEqual(zulip_realm, lear_realm)` making the test easier
to read.
A confirmation object is already created when
do_send_confirmation_email is called just above.
Tweaked by tabbott to remove an unnecessary somewhat hacky database
query.
Fixes#1727.
With the server down, apply migrations 0245 and 0246. 0246 will remove
the pub_date column, so it's essential that the previous migrations
ran correctly to copy data before running this.
This is also a useful preparatory refactor for having a user setting
controlling whether one's own email address is publicly available
within the organization.
We don't actually need to go to the memcached (falling back to the
database) to fetch either user or client objects on every event. For
user objects, we actually can just pass through the user ID
transparently; for client objects, we can use an in-process cache,
since the mapping of string to ID never changes.
This simple backwards-compatible change saves approximately 12% in the
compressed size of the chat.zulip.org page_params. We can do much,
much better by changing the format, but this seems like a good
intermediate step.

After a new user joins an active organization, it isn't obvious what
to do next; this change causes there to be recent unread messages in
the stream sidebar for the user to click on to get a feel for what's
happening in the organization and experiment with Zulip.
Fixes#6512.
Apparently, get_active_presence_idle_user_ids, which is carefully
optimized to only fetch data for users who might actually need
notification processing, was only considering PMs and direct mentions,
not wildcard mentions or alert words.
This caused some pretty weird failure modes when working on adding
support for broader mention notifications, because users who had one
of these types of notifications would be treated as never
presence-idle, which was just confusing.
This is part of adding support for notifications for wildcard mentions
and alert words; it's worth merging this as an early commit because
the consequence of not doing this are very difficult to debug.
The `users/me/subscriptions` endpoint accidentally started returning
subscriber information for each stream. This is convenient, but
unnecessarily costly for those clients which either don't need it
(most API apps) or already acquire this information via /register
(including Zulip's apps).
This change removes that data set from the default response. Clients
which had come to rely on it, or would like to rely on it in future,
may still access it via an additional documented API parameter.
Fixes#12917.
It was allowing us to get away with wrong types on a few functions:
`check_send_typing_notification` and `send_notification_backend` can be
(and are) called with a list of `int` as `notification_to`, not just a
list of `str`.
The problem it was working around already had a better solution using
the dummy `type` argument. Use that.

This feature is intended to cover all of our ways of exporting a
realm, not just the initial "public export" feature, so we should name
things appropriately for that goal.
Additionally, we don't want to include data exports in page_params;
the original implementation was actually buggy and would have.
When a person creates a new realm, they'll likely want to create a
bunch of initial streams at once. When doing so, it could be annoying
to have to mark all of the new stream notification messages as read.
Thus to make this process smoother, we should automatically mark
the messages generated by the Notification Bot in the notifications
(announcements) stream, as well as in the newly created stream itself
as read by the stream creator.
Fixes#12765.
