We start by including functions that do custom
queries for topic history.
The goal of this library is partly to quarantine
the legacy "subject" column on Message.
This is a preparator refactor for supporting hosting different Tornado
processes on different servers; to look up which Tornado server we
should be sending the event to, we'll need the realm object.
This supports guest user in the user-info-form-modal as well as in the
role section of the admin-user-table.
With some fixes by Tim Abbott and Shubham Dhama.
Bots are not allowed to use the same name as
other users in the realm (either bot or human).
This is kind of a big commit, but I wanted to
combine the post/patch (aka add/edit) checks
into one commit, since it's a change in policy
that affects both codepaths.
A lot of the noise is in tests. We had good
coverage on the previous code, including some places
like event testing where we were expediently
not bothering to use different names for
different bots in some longer tests. And then
of course I test some new scenarios that are relevant
with the new policy.
There are two new functions:
check_bot_name_available:
very simple Django query
check_change_bot_full_name:
this diverges from the 3-line
check_change_full_name, where the latter
is still used for the "humans" use case
And then we just call those in appropriate places.
Note that there is still a loophole here
where you can get two bots with the same
name if you reactivate a bot named Fred
that was inactive when the second bot named
Fred was created. Also, we don't attempt
to fix historical data. So this commit
shouldn't be considered any kind of lockdown,
it's just meant to help people from
inadvertently creating two bots of the same
name where they don't intend to. For more
context, we are continuing to allow two
human users in the same realm to have the
same full name, and our code should generally
be tolerant of that possibility. (A good
example is our new mention syntax, which disambiguates
same-named people using ids.)
It's also worth noting that our web app client
doesn't try to scrub full_name from its payload in
situations where the user has actually only modified other
fields in the "Edit bot" UI. Starting here
we just handle this on the server, since it's
easy to fix there, and even if we fixed it in the web
app, there's no guarantee that other clients won't be
just as brute force. It wasn't exactly broken before,
but we'd needlessly write rows to audit tables.
Fixes#10509
We could migrate all the current PREMIUM_FREE organizations to have more
invites, but this setting mainly affects orgs right as they are starting, so
it's probably fine.
We use UserMessageLite to avoid Django overhead, and we
do updates in chunks of 10000. (The export may be broken
into several files already, but a reasonable chunking at
import time is good defense against running out of memory.)
Fixes the urgent part of #10397.
It was discovered that soft-deactivated users don't get mobile push
notifications for messages on private streams that they have configured
to send push notifications.
Reason: `handle_push_notification` calls `access_message`, and that
logic assumes that a user who is a recipient of a message has an
associated UserMessage row. Those UserMessage rows are created
lazily for soft-deactivated users, so they might not exist (yet)
until the user comes back.
Solution: Ensure that userMessage row is created for
stream_push_user_ids and stream_email_user_ids in create_user_messages.
In user type custom field, field value is list of user ids. We weren't
converting list to json object in update event payload. This throws
error in frontend, cause we store stringify representation of custom
field value. Therefore, after update event is recieved field-value-
type gets updated to array from string which throws json parsing error.
Using early-exit here allows us to more easily
comment why there are certain exemptions to
this logic.
We also only require callers to pass in realm,
not the whole user object.
This prevents leaking some variables into an already
cluttered function.
We also add test coverage for what's now an
early-exit condition in the new function--we exempt
public MIT streams from these events.
This change was partially driven by a quirk in Python
where peephole optimizations make `continue` lines
appear not to be covered.
I also think it's generally a good idiom to extract
functions for loop bodies when they don't actually
accumulate values or maintain other state. With this
commit we now prevent potential bugs for vars like
`is_stream` leaking between loop iterations.
We simulate a race condition by mocking create_user
to actually create a user, but then raise an
IntegrityError (as if another process had actually
created the user, not our test).
I also changed the real code to use explicitly
named parameters.
Our get_streams_traffic function used to query
all streams in the StreamCount table if you
passed in `None` for `streams`.
Now we require that you pass in a list of
stream_ids.
I don't know how much work this will save
the database, since probably the bulk of
the work is aggregating. If we need to fine
tune DB performance, we could possibly add
`realm` as an argument and add it to the filter.
What we'll immediately get, for large multi-realm
installations, is less data over the wire and
less work for the ORM.
The prior code uses an awkward idiom that
pre-dates the `exists()` function, and it
had an unreachable line of code.
The new version should be faster, since we
don't create a throwaway heavy Django object
or send needless data over the wire.
This functions appears to be redundant to
`access_stream_by_name`. The only
meaningful line of code in the function that we're
removing, the code that raises an error,
appears to be unreachable, despite reasonably
extensive tests.
The only thing the function was restricting
was that the case where the bot's owner was
unsubscribed to a private stream, which
is already locked down in
`access_stream_by_name` calls inside of
`patch_bot_backend`.
This commit increases test coverage
by removing unreachable code.
It's possible this function had
some theoretical value before we
introduced the `require_non_guest_human_user`
decorator to the `patch_bot_backend`
view, since in theory the bot itself
could have subscribed to a stream that
the owner didn't subscribe to. Even
then it's not clear that allowing the
bot to set that as a default stream
would have been harmful, since they
can already access it.
We want our methodology for extracting the last message
id to be consistent, particularly in terms of how we
handle edge cases. (I'll concede that the
`bulk_remove_subscriptions` codepath never hits that
corner case in practice, but it's harmless to handle
the theoretical case.)
It may also be nice to have this function show up
clearly in profiling.
This also adds some direct testing to the function.
It's not clear to me why we don't use `latest('id')`
in the implementation, but that's outside the scope
of this commit.
This de-clutters check_message a bit and also makes
it easy to audit our rules for who can write to a
stream.
Also, this works around a bug with Python where its
optimizations for the `pass` instruction make them
not appear to run and show up as uncovered in
coverage reports.
Right now it only has one function, but the function
we removed never really belonged in actions.py, and
now we have better test coverage on actions.py, which
is an important module to get to 100%.
This uses the recently introduced active_mobile_push_notification
flag; messages that have had a mobile push notification sent will have
a removal push notification sent as soon as they are marked as read.
Note that this feature is behind a setting,
SEND_REMOVE_PUSH_NOTIFICATIONS, since the notification format is not
supported by the mobile apps yet, and we want to give a grace period
before we start sending notifications that appear as (null) to
clients. But the tracking logic to maintain the set of message IDs
with an active push notification runs unconditionally.
This is designed with at-least-once semantics; so mobile clients need
to handle the possibility that they receive duplicat requests to
remove a push notification.
We reuse the existing missedmessage_mobile_notifications queue
processor for the work, to avoid materially impacting the latency of
marking messages as read.
Fixes#7459, though we'll need to open a follow-up issue for
using these data on iOS.
Fixes a regression introduced in 23246ff816.
However, we'll be shortly removing this feature, since it's legacy
support for an app that no longer is supported.
The "/stats" command doesn't actually do anything
interesting yet, and it also writes to the message
feed instead of replying directly to the user.
The history of this command was that it was
written during a PyCon sprint. It was mainly intended
as an example for subsequent slash commands. The
ones we built after "/stats" have sort of outgrown
"/stats" and don't follow the original structure
for "/stats". (The "/day", "/ping", and "/settings"
commands were built shortly after.)j
We probably want to ressurect "/stats" fairly soon,
after figuring out some useful stats and refining
the UI.
As you can see from this commit, resurrecting the
code here shouldn't be too difficult, but it
may actually be pretty rare that we just translate
slash commands into fleshed out messages.
random_api_key, the function we use to generate random tokens for API
keys, has been moved to zerver/lib/utils.py because it's used in more
parts of the codebase (apart from user creation), and having it in
zerver/lib/create_user.py was prone to cyclic dependencies.
The function has also been renamed to generate_api_key to have an
imperative name, that makes clearer what it does.
Now reading API keys from a user is done with the get_api_key wrapper
method, rather than directly fetching it from the user object.
Also, every place where an action should be done for each API key is now
using get_all_api_keys. This method returns for the moment a single-item
list, containing the specified user's API key.
This commit is the first step towards allowing users have multiple API
keys.
Renaming a user group to a name shared by other group wasn't a scenario
handled by the backend, and the server errored whenever this was
attempted.
Now a json_error is returned, letting the user know that a user group
with that name already exists.
When last user(only in case of admin) unsubscribe from private stream,
stream page doesn't get updated. Cause we delete the private stream
as soon as last user unsubscribe from stream.
So `sub` get undefined in frontend, cause that stream is deleted
before unsubscribe-user-from-stream event is received.
Fix this by changing order of events sent to frontend. Event
`subscription: remove` should be sent before `stream: delete` event
from backend.
This ensures that the format of this data structures matches that for
in-realm bots in the main users data structure (including avatars,
etc.).
Fixes#10138.
We were getting event-handling exceptions in JS in production if a new
user was created and then went and set a custom profile field, because
there was no `.profile_data` on their user object. We were able to
trace the issue down to the fact that our events didn't include that
field when creating a new user.
This renames Realm.restricted_to_domain field to
emails_restricted_to_domains, for greater clarity as to what it does
just from seeing the setting name, without having to look it up.
Fixes part of #10042.
A stream created in the last few hours likely won't be in StreamCount
(since that gets updated once a day), and hence won't be in the
recent_traffic dict.
However, get_average_weekly_stream_traffic should be None in this case,
not 0.
This refactors the generate_topic_history_from_db_rows function to not
depend upon the assumption of rows passed as parameter to be sorted in
reverse order of max_message_id field.
Additionally, we add sorting and some tests that verify correct
handling of these cases.
In this commit we add a new endpoint so as to have a way of fetching
topic history for a given stream id without having to be logged in.
This can only happen if the said stream is web public otherwise we
just return an empty topics list. This endpoint is quite analogous
to get_topics_backend which is used by our main web app.
In this commit we also do a bit of duplication regarding the query
responsible for fetching all the topics from DB. Basically this
query is exactly the same as what we have in the
get_topic_history_for_stream function in actions.py. Basically
duplicating now is the right thing to do because this query is
really gonna change when we add another criteria for filtering
messages which is:
Only topics for messages which were sent during the period the
corresponding stream was web public should be returned.
Now when we will do this, the query will change and thus it won't
really be a code duplication!
Fixes#7665
In case of invitation events, 'invites_changed' event without
any real payload is sent to all the realm admins and the user.
The event is handled by reloading the list to view recent changes.
Commit tweaked by shubhamdhama:
* Send an `invite_changed` event when an user accept an invite.
Also, added the test for the same.
* No need to delete the invite list in frontend, current logic
handles the case when the invite data is changed properly.
* Extracted the common logic for sending an event into
`notify_invites_changed`.
This is all the plumbing that makes it possible to enable the
stream_email_notifications setting via the Zulip API. The flag still
doesn't do anything yet, but this is a nice checkpoint along the way
to implementing this feature.
This commit creates a new field called delivery_email. For now, it is
exactly the same as email upon user profile creation and should stay
that way even when email is changed, and is used only for sending
outgoing email from Zulip.
The purpose of this field is to support an upcoming option where the
existing `email` field in Zulip becomes effectively the user's
"display email" address, as part of making it possible for users
actual email addresses (that can receive email, stored in the
delivery_email field) to not be available to other non-administrator
users in the organization.
Because the `email` field is used in numerous places in display code,
in the API, and in database queries, the shortest path to implementing
this "private email" feature is to keep "email" as-is in those parts
of the codebase, and just set the existing "email" ("display email")
model field to be something generated like
"username@zulip.example.com" for display purposes.
Eventually, we'll want to do further refactoring, either in the form
of having both `display_email` and `delivery_email` as fields, or
renaming "email" to "username".
We extract out the logic for generating a list of all historical
topics for a given stream as a separate function. This avoids code
duplication when we add the similar code path for grabbing all topics
for web public streams.
The main remaining todo for correctly populating
RealmAuditLog.requires_billing_update is supporting the de-seating (and
corresponding re-seating) that happens after being offline for two weeks.
The only changes visible at the AST level, checked using
https://github.com/asottile/astpretty, are
zerver/lib/test_fixtures.py:
'\x1b\\[(1|0)m' ↦ '\\x1b\\[(1|0)m'
'\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n'
which is fine because re treats '\\x1b' and '\\n' the same way as
'\x1b' and '\n'.

An estimated traffic of 0 suggests a stream is dead, and has pretty
different semantics from any non-zero value. So we should round up any
number between 0 and 1 to 1.
We don't ever use this value, but it's confusing to have the incorrect
calculation in the code.
Ideally we would set this to "None", but I don't know the code well enough
to be confident nothing would break.
We've for a long time had the behavior that a bot mentioned in a
stream message receives the notification, regardless of whether the
bot was actually subscribed to the stream.
Apparently, this behavior also triggered if you mentioned a bot in a
private message (i.e. the bot would be delievered the private message
and would probably respond unhelpfully in a new group private message
thread with the PMs original recipients plus the bot).
The fix for this bug is simple: To exclude this feature for private
messages.
This fixes an issue where if you make #announce (the default
announcement stream) announce-only, then creating a new stream will
throw an exception (because notification-bot can't send there).
Fixes#9636.
The user can now specify the value while creating a stream.
An admin can later change it via `Change stream permissions`
modal. Add is_announcement_only to subscription type text.
For some reason in my original version I was sending both
content and data to the client for submessage events,
where data === JSON.parse(content). There's no reason
to not just let the client parse it, since the client
already does it for data that comes on the original
message, and since we might eventually have non-JSON
payloads.
The server still continues to validate that the payload
is JSON, and the client will blueslip if the server
regressses and sends bad JSON for some reason.
API users, particularly bots, can now send a field
called "widget_content" that will be turned into
a submessage for the web app to look at. (Other
clients can still rely on "content" to be there,
although it's up to the bot author to make the
experience good for those clients as well.)
Right now widget_content will be a JSON string that
encodes a "zform" widget with "choices." Our first
example will be a trivia bot, where users will see
something like this:
Which fruit is orange in color?
[A] orange
[B] blackberry
[C] strawberry
The letters will be turned into buttons on the webapp
and have canned replies.
This commit has a few parts:
- receive widget_content in the request (simply
validating that it's a string)
- parse the JSON in check_message and deeply
validate its structure
- turn it into a submessage in widget.py
This should significantly improve the user experience for creating
additional accounts on zulipchat.com.
Currently, disabled in production pending some work on visual styling.
We extract the entire operations of the management command to a
function create_if_missing_realm_internal_bots in the
zerver/lib/onboarding.py. The logic for determining if there are any realm
internal bots which have not been created is extracted to a function
missing_any_realm_internal_bots in actions.py.
If a user's account has been deactivated, we want to provide a special
error message that makes clear what's going on.
Future work is to provide some administrative controls on whether a
user should be able to re-activate their account.
The only slash command implemented in this initial
version is an extremely crippled version of a
"/stats" slash command that reports that you are
running 1 server.
- do_change_is_admin now raises AssertionError when a non-admin
permission is given.
- adds test to test_users to ensure admin asserts on invalid
permission values.
It makes sense to refactor out the last_reminder logic out of
send_pm_if_empty_stream and have a generic function that can send
rate-limited PM notifications to a bot owner and can be used by
methods other than send_pm_if_empty_stream.
We send add events on upload, update events when sending a message
referencing it, and delete updates on removal.
This should make it possible to do real-time sync for the attachments
UI.
Based in part on work by Aastha Gupta.
A typo in my reading of 6cc2e8bbff meant
that we were incorrectly doing database queries for each Service
object, just to get the user_profile.id, which we already had.
This eliminates the need to call user_ids_to_users inside the
get_service_dicts_for_bots code path, saving a database query.
This completes my refactor to fix backend performance issues in this
code path. Previously, our messy layering of queries that resulted in
Zulip doing work even if none of the bots actually had Services or
config_data.
This commit adds a new field history_public_to_subscribers to the
Stream model, which serves a similar function to the old
settings.PRIVATE_STREAM_HISTORY_FOR_SUBSCRIBERS; we still use that
setting as the default value for new streams to avoid breaking
backwards-compatibility for those users before we are ready with an
actual UI for users to choose directly.
This also comes with a migration to set the value of the new field for
existing streams with an algorithm matching that used at runtime.
With significant changes by Tim Abbott.
This is an initial part of our efforts on #9232.
The removed code path was only needed due to buggy setup code in the
test_cross_realm_scenarios test. We address that with a less buggy
workaround, and which lets us remove unnecessary complexity from this
important validation function.
Thanks for Umair Waheed for some preliminary work on this.
Fixes#7561.
Add realm setting to set time limit for message deleitng.
Set default value of message_content_delete_limit_seconds
to 600 seconds(10 min).
Thanks to Shubham Dhama for rebasing and reworking this. Some final
edits also done by Tim Abbott.
Fixes#7344.
This is a simple computed field. It's intended to more clearly
capture the meaning of this restriction for the users in zephyr mirror
realms, and eventually support guest user accounts in normal Zulip
realms.
This is part of the effort to remove the use of is_zephyr_mirror_realm
across the code path for situations that might be relevant for other
users. It helps keep the code readable.
This commit sends the event for renaming of a private stream to
organization admins of the realm, in addition to the obvious list of
subscribers of the private stream.
Normally, admins can manage a private stream (e.g. unsubscribing a
user). But when the admin tried to unsubscribes a user from a
previously renamed stream, we previously were throwing a JS error, as
the webapp hadn't been notified about the new stream name.
Fixes#9034.
Remove models.get_user_profiles_by_ids() and
obtain user's bots profiles in actions.get_service_dicts_for_bots() by
users.user_ids_to_users() instead of models.get_user_profiles_by_ids().
Fixes#8939
Implement few optimizations for reading admin's bot dicts from database
for a constants number of requests:
- add models.get_user_profiles_by_ids() for reading bots profiles
by single query from database
- add models.get_services_for_bots() for reading services for bots
by single query from database
- add bot_config.get_bot_configs() for reading config data for bots
by single query from database
Fixes#8838
Fixes#8853.
In certain cases, the browser is not able to look up the message.
Include the recipient data for the message in the delete_message event,
so look up of those attributes by the browser isn't required.
This bot was basically a duplicate of NOTIFICATION_BOT for some
specific corner cases, and didn't add much value. It's better to just
eliminate it, which also removes some ugly corner cases around what
happens if the user account doesn't exist.
webhook-errors.log file is cluttered with Stream.DoesNotExist
errors, which hides the errors that we actually need to see. So,
since check_message already sends the bot_owner a PM if the webhook
bot tries to send a message to a non-existent stream, we can ignore
such exceptions.
Add function in user-groups.py for getting member ids
for a group.
Update view to enforce checks for modifying user-groups.
Only admins and user group members can modify user-groups.
There were two instances of `ensure_stream` being called and assigned to
a variable with the variable not being used elsewhere. pyflakes picked
up on this (where it didn't in the previous version likely due to tuple
unpacking), so the the variable assignment has been replaced with a call
to `ensure_stream`.
Issue #2088 asked for a wrapper to be created for
`create_stream_if_needed` (called `ensure_stream`) for the 25 times that
`create_stream_if_needed` is called and ignores whether the stream was
created. This commit replaces relevant occurences of
`create_stream_if_needed` with `ensure_stream`, including imports.
The changes weren't significant enough to add any tests or do any
additional manual testing.
The refactoring intended to make the API easier to use in most cases.
The majority of uses of `create_stream_if_needed` ignored the second
parameter.
Fixes: #2088.
This commit migrates realm emoji to be addressed by their `id` rather
than their name. This fixes a long standing issue which was causing
an error on uploading an emoji with same name as a deactivated realm
emoji.
Fixes: #6977.
We disabled the original "colorized HTML edit-history" feature way
back in 2013 in c51056ff8e.
That original feature involved showing what had been edited inline in
message bodies, so one could easily see what had been changed.
That old feature has since been replaced with the "view edit history"
menu option, and we're unlikely to ever want the old feature back.
So, we can just remove its code. There's a few supporting variables
that were created to help implement this; we can clean those up and
simplify the `update_message` code now that this feature is fully
removed.
This applies only on a server open for anyone to create a realm.
Moreover, if the server admins have granted any given realm a
max_invites greater than the default, that realm is exempt too.
This fixes an unpleasant regression in
f5edeb01ae, where we stopped correctly
filtering users who have an open browser session that's idle. These
users are tagged as "UserPresence.IDLE" with an current timestamp in
the database, and should be treated as idle for presence purposes.
As a result, if you had an open Zulip browser session, you incorrectly
wouldn't get missed-message emails for PMs and mentions before this fix.
Currently, when other private stream subscriber add realm admin to
stream, new copy private stream is created in realm admin's streams.
Which resulted in error, cause there are two similar stream element
in stream settings.
If new subscriber is added to private stream, we first send them
stream `create` event, cause private stream are not visible until
user don't get subscribed at least once. But realm admins can now
always access private stream, so when realm admin is subscribed to
stream, realm admin get stream `create` event even if stream already
exist in on realm admin client side.
Fix this by extracting realm admins from stream `create` event on
`add` subscription operation and sending private stream `create`
event to all realm admins on stream creation operation.
Fixes#8695
This commit adds a generic function called check_send_webhook_message
that does the following:
* If a stream is specified in the webhook URL, it sends a stream
message, otherwise sends a PM to the owner of the bot.
* In the case of a stream message, if a custom topic is specified
in the webhook URL, it uses that topic as the subject of the
stream message.
Also, note that we need not test this anywhere except for the
helloworld webhook. Since helloworld is our default example for
webhooks, it is here to stay and it made sense that tests for a
generic function such as check_send_webhook_message be tested
with an actual generic webhook!
Fixes#8607.
This will allow realm admins to access subscribers of unsubscribed
private stream. This is a preparatory commit for letting realm admins
remove those users.
Apparently, we did essentially all the work to support showing full
topic history to newly subscribed users from a data flow perspective,
but didn't actually enable this feature by having the topic history
endpoint grant access to historical topics. This fixes that gap.
I'm not altogether happy with how the code and tests read for this
feature; the code itself has more duplication than I'd like, and the
tests do too, but it works.
If new private stream is created by realm admin without realm admin
subscribed to it, then it doesn't automatically add created stream to
realm admin's stream list. We have to reload the browser to get newly
created stream in stream list. Cause private stream creation event is
only sent to the subscribed users to private stream, so even if realm
admin is acting user, they don't get creation event.
We should send private stream creation event to realm admin users along
with subscribed user to stream, as realm admins can access unsubscribed
private streams.
Tweaked by tabbott to fix various typos and clean up the code.
Adds realm_bot delete event. On bot ownership change, add event is
sent to the bot_owner(if not admin) and delete event to the
previous bot owner(if not admin). For admin, update event is sent.
This sets up a new test class with a simple
test, mostly for increasing coverage. The class
should in the future be extended to properly
verify the handle_feedback() logic.
Previously, when a user updated the config data of an
embedded bot, only the updated fields were dispatched
back to the client. Dispatching all config data fields
makes the client updating code less brittle.
models.py should only contain thin wrapper functions. Furthermore,
this move allows us to remove the circular imports. The two moved
functions are interdependent and are thus moved in one commit.
Creating the very first organization administrator user and
subscribing them to streams before any messages were sent resulted in
RealmAuditLog entries being created with a `event_last_message_id` of
None, because that's the maximum ID in the empty set.
We correct this by fixing the incorrectly created RealmAuditLog
entries, both for new servers and also fixing old broken entries on
existing servers.
This fixes an issue where if a user setup a Zulip server with just the
organization administrator, and then forgot about it (so that the
initial user became soft-deactivated), trying to sign in 3 weeks later
would throw an exception.
This fixes the issue reported here:
https://chat.zulip.org/#narrow/stream/9-issues/subject/500.20error.20on.20login/near/511981
This adds button under "Organization profile" settings, which
deactivates the organization and sends an "event" to all the
active user and log out them.
Fixes: #8212.
This is based on usage in bulk_change_user_names.py, and that
the RealmAuditLog acting_user field is Optional[UserProfile].
This could be more meaningfully changed in future, perhaps to
indicate that the command was run by a specific zulip user.
In order to get test coverage on topic name checks, we
do them in Addressee, so that we don't hit an assertion
first. The assertion in question is in Addressee.topic(),
and it was added partly to appease mypy.
Adds a check for newline that was present on backend, but missing in the
frontend markdown implementation. Updating messages uses is_me_message flag
received from server instead of its own partial test. Similarly, rendering
previews uses markdown code.
Fixes#6493.
This is the first step for allowing users
to edit a bot's service entries, name the
outgoing webhook configuration entries. The
chosen data structures allow for a future
with multiple services per bot; right now,
only one service per bot is supported.
We add two functions:
1.) check_schedule_message(): This function is responsible for
doing the essential initial checkes to verify the validity of
the message. These checkes include things like if user is
allowed to send messages to some stream or not or if the user is
a super_user. All this is basically done by further calling
check_message() with appropriate parameters. This is on the same
lines as is check_send_message().
2.) do_schedule_messages(): This function is responsible for
creating ScheduleMessage table rows for a list of messages that
are to be scheduled. This basically accumulates the ScheduleMessage
objects in a list and then bulk creates the rows.
The original logic is buggy now that emails can belong to (and be
invited to) multiple realms.
The new logic in the `invites` queue worker also avoids the bug where
when the PreregistrationUser was gone by the time the queue worker got
to the invite (e.g., because it'd been revoked), we threw an exception.
[greg: fix upgrade-compatibility logic; add test; explain
revoked-invite race above]
This code changes frequently enough that errors are bound to creep in. The
main change is that this sends the original invitation email instead of the
reminder email, but I think that's fine.
[Modified by greg to (1) keep `USERNAME_FIELD = 'email'`,
(2) silence the corresponding system check, and (3) ban
reusing a system bot's email address, just like we do in
realm creation.]
As we migrate to allow reuse of the same email with multiple realms,
we need to replace the old "no email reuse" validators. Because
stealing the email for a system bot would be problematic, we still ban
doing so.
This commit only affects the realm creation logic, not registering an
account in an existing realm.
We would allow a user with a valid invitation for one realm to use it
on a different realm instead. On a server with multiple realms, an
authorized user of one realm could use this (by sending invites to
other email addresses they control) to create accounts on other
realms. (CVE-2017-0910)
With this commit, when sending an invitation, we record the inviting
user's realm on the PreregistrationUser row; and when registering a
user, we check that the PregistrationUser realm matches the realm the
user is trying to register on. This resolves CVE-2017-0910 for
newly-sent invitations; the next commit completes the fix.
[greg: rewrote commit message]
This fixes some subtle JavaScript exceptions we've been getting in
zulipchat.com, caused by the system bot realm there not being "zulip"
interacting with get_cross_realm_users.
This should help protect us from future issues with the way that
`bulk_get_users` does caching.
It's likely that we'll want to further restructure `bulk_get_users` to
not have this base_query code path altogether (since it's kinda
buggy), but I'm going to defer that for a time when we have another
user.
We include ERROR_BOT in this set, even though it's not technically
cross-realm (it just lives in the admin realm).
This code path does not correctly handle emails that correspond to
multiple accounts (because `get_system_bot` does not). Since it's
intended to only be used by system bots, we add an appropriate
assertion to ensure it is only used for system bots.
Previously, this was a ValidationError, but that doesn't really make
sense, since this condition reflects an actual bug in the code.
Because this happened to be our only test coverage the ValidationError
catch on line 84 of registration.py, we add nocoverage there for now.
This fixes a bug where, when a user is unsubscribed from a stream,
they might have unread messages on that stream leak. While it might
seem to be a minor problem, it can cause significant problems for
computing the `unread_msgs` data structures, since it means we need to
add an extra filter for whether the user is still subscribed, either
in the backend or in the UI.
Fixes#7095.
This often can cause minor caching problems.
Obviously, it'd be better if we had access to the AST and thus could
do this rule for UserProfile objects in general.
This endpoint will allow us to add/delete emoji reactions whose emoji
got renamed during various emoji infra changes. This was also a
required change for realm emoji migration.
This commit was tweaked significantly by tabbott for greater clarity
(with no changes to the actual logic).
In remove_members_from_group_backend, we are passing user group to
remove_members_from_user_group. In remove_members_from_user_group,
expect user_group_id.
This fixes a regression in ae5ba7f4fd,
where Zulip would 500 if the newly added system bots didn't exist on
the server.
This also fixes a moderate size performance problem where we'd fetch 5
users from memcached or the database in a loop.
Generally emails are not written with markdown in mind and hence
sometimes render in strange ways. This commit fixes a particular
issue that was causing whitespace before paragraphs to be treated
as code block due to which email content was being rendered in a
box that scrolls in right direction a lot.
Fixes: #7045.
The original PR to allow generic bots to be mentioned had
some merge issues that we detected about a week after the
fact. This commit restores the logic from the original PR.
The reason we didn't detect this bug earlier is that the
merge issues didn't break any existing behavior. Instead,
they made it so that only UserMessage rows got written for
bots, but no events were being set. The part of the commit
that got lost is restored here, so now events get sent as
well.
Thanks to @derAnfaenger for reporting this and being patient
as we tracked it down.
Fixes#7140
We extract get_bulk_stream_subscriber_info() from this
function to remove some of the complexity. Also, in that
new function we avoid a hop to the database by querying
on stream ids instead of recipient ids. The query that
gets changed here does require a join to the recipient
table (to get the stream id), so it's a little bit of a
tradeoff.
There's an implicit assumption in bulk_remove_subscriptions
that all users belong to the same realm. We use the realm
for things like comparing occupied streams before and
after our main operation of deactivating streams.
Before this change, we just used the user_profile variable
that leaked from some prior loop to look up the realm, which
was super brittle.
Now we're a bit more explicit.
Note that this code leads to a slightly different query, because
we join to one row in the small Recipient table to match
stream_id to recipient.type_id.
The first method we extract to this library is
get_active_subscriptions_for_stream_id().
We also move num_subscribers_for_stream_id() to here, which
is slightly annoying (having the method on Stream was nice)
but avoids some circular dependency issues.
