This utilizes the generic `BaseNotes` we added for multipurpose
patching. With this migration as an example, we can further support
more types of notes to replace the monkey-patching approach we have used
throughout the codebase for type safety.
The motive of adding `BaseNotes` was to support monokey patching
temporary attributes to objects (such as `.trigger` on `Message`) when
working on the django-stubs migration in #18777.
This way, we no longer have to manually keep the upload path code in
sync with the upload path code in zerver/lib/upload.py.
This was originally suggested in
https://github.com/zulip/zulip/pull/19478#issuecomment-911479530.
This change fixes a bug when importing into a server using the local
file uploads backend, where the `import_realm.py` copy wasn't using
our standard 256-directory approach to avoid putting too many files in
a single directory.
de04f0ad67 changed now notifications recipients were calculated, in
a manner that caused them to be sent when they should not have been.
ac70a2d2e1 was supposed to resolve this, but appears to have been
insufficient, as all three of these cases have been observed to still
happen.
Add safety checks immediately before notification, until the
underlying logic error can be sussed out.
This information can be gleaned from the stacktrace, but making it
explicit in the stringification makes it much easier to differentiate
types of errors at a glance, particularly in Sentry.
We move the emojiset_choices method from UserProfile class to
UserBaseSettings class because emojiset_choices exists in
UserBaseSettings class and this would be used for realm-level
settings as well along with existing user-level settings.
We rename the user group in the example for 'GET /user_groups'
with is_system_group=True, to be 'Moderators' as is_system_group
will be set to True for role-based user groups only.
The default is kept as no retries. Since retries with exponential
backoff are a good thing to make easy, the int form defaults to
setting a backoff_factor.
Unfortunately, urllib3 retry backoff does not implement jitter.
Switching this to use the `backoff` library[1] rather than urllib3's
native Retry is left as future extension.

This adds the X-Smokescreen-Role header to proxy connections, to track
usage from various codepaths, and enforces a timeout. Timeouts were
kept consistent with their previous values, or set to 5s if they had
none previously.
This commits removes some unnecessary checks for `self.md.zulip_message`,
which were put there historically, as earlier we used to add the additional
properties like mentions_user_ids, alert_words, etc. to Message dict
only. These were later moved to MessageRenderingResult class in commit
75cea329b but the checks weren't removed.
This is important because while rendering the messages imported from
other chat tools (like Rocket.Chat), the Message dict is not passed to
the markdown, due to which the checks for `self.md.zerver_message` fails
and hence, things like user mentions, stream/topic mentions are not
rendered in the imported messages properly.
The `user_activity_interval` worker calls:
```python3
last = UserActivityInterval.objects.filter(user_profile=user_profile).order_by("-end")[0]
`````
Which results in a query like:
```sql
SELECT "zerver_useractivityinterval"."id", "zerver_useractivityinterval"."user_profile_id", "zerver_useractivityinterval"."start", "zerver_useractivityinterval"."end" FROM "zerver_useractivityinterval" WHERE "zerver_useractivityinterval"."user_profile_id" = 12345 ORDER BY "zerver_useractivityinterval"."end" DESC LIMIT 1
```
For users which have at least one matching row, this results in a
query plan like:
```
Limit (cost=0.56..711.38 rows=1 width=24) (actual time=0.078..0.078 rows=1 loops=1)
-> Index Scan Backward using zerver_useractivityinterval_7f021a14 on zerver_useractivityinterval (cost=0.56..1031399.46 rows=1451 width=24) (actual time=0.077..0.078 rows=1 loops=1)
Filter: (user_profile_id = 12345)
Rows Removed by Filter: 98
Planning Time: 0.059 ms
Execution Time: 0.088 ms
```
But for users that have just been created, with no matching rows, this
is considerably more expensive:
```
Limit (cost=0.56..711.38 rows=1 width=24) (actual time=10798.146..10798.146 rows=0 loops=1)
-> Index Scan Backward using zerver_useractivityinterval_7f021a14 on zerver_useractivityinterval (cost=0.56..1031399.46 rows=1451 width=24) (actual time=10798.145..10798.145 rows=0 loops=1)
Filter: (user_profile_id = 12345)
Rows Removed by Filter: (count of every single row in the table, redacted)
Planning Time: 0.053 ms
Execution Time: 10798.158 ms
```
Regular vacuuming can force the use of the index on `user_profile_id`
as long as there are few enough users, which is fast -- however, at
some point, the query planner decides that is insufficiently specific,
always chooses the effective-whole-table-scan.
Add an index on `(user_profile_id, end)`, which is expected to be
sufficiently specific that it is used even with large numbers of user
profiles.
Ref #19250.
The transforms called from `build_message_payload` use
`lxml.html.fromstring` to parse (and stringify, and re-parse) the HTML
generated by Markdown. However, this function fails if it is passed
an empty document. "empty" is broader than just the empty string; it
also includes any document made entirely out of control characters,
spaces, unpaired surrogates, U+FFFE, or U+FFFF, and so forth. These
documents would fail to parse, and raise a ParserError.
Using `lxml.html.fragment_fromstring` handles these cases, but does by
wrapping the contents in a <div> every time it is called. As such,
replacing each `fromstring` with `fragment_fromstring` would nest
another layer of `<div>`.
Instead of each of the helper functions re-parsing, modifying, and
stringifying the HTML, parse it once with `fragment_fromstring` and
pass around the parsed document to each helper, which modifies it
in-place. This adds one outer `<div>`, requiring minor changes to
tests and the prepend-sender functions.
The modification to add the sender is left using BeautifulSoup, as
that sort of transform is much less readable, and more fiddly, in raw
lxml.
Partial fix for #19559.
This is a roundabout way to appease a semgrep complaint about
‘error_msg = error_msg % (string_id,)’ while also improving the code.

9ac55a8cf6 introduced support for
batch updates to stories. However, that commit didn't skip label
removals, as we already do in non-batch story payloads. This led
to an exception for batch story update payloads where labels were
removed but none were added.
maybe_send_batched_emails handles batches of emails from different
users at once; as it processes each user's batch, it enqueues messages
onto the `email_senders` queue. If `handle_missedmessage_emails`
raises an exception when processing a single user's email, no events
are marked as handled -- including those that were already handled and
enqueued onto `email_senders`. This results in an increasing number
of users being sent repeated emails about the same missed messages.
Catch and log any exceptions when handling an individual user's
events. This guarantees forward progress, and that notifications are
sent at-most-once, not at-least-once.
This commit indicates that the realm_message_retention_days field can have
a special value, similar to its stream counterpart, and also explains how
the special value changed over different server versions.

The ability to use multiple ports has been removed a long time ago.
And the "optional" note in the help message is in fact incorrect
since `addrport` being `None` is not supported.
We do not allow any user to edit the system user groups (including
renaming, deleting, adding or removing members, etc.) from the
API. These user groups will change only by the code when a new
user is added or role of a user is changed.
This is implemented by rejecting access_user_group_by_id always
except the case when it is use to get the user group for sending
email and push notifications, as we would need to send notifications
to the mentioned user group.
We make the description parameter in create_user_group as keyword-only
to improve readability. We would also keep the is_system_group
parameter which will be added in future keyword-only.
Tuples cannot be deserialized from JSON.
While we do use these validators for other things, like event
dictionaries, we have migrated the API away from using those. The
last use was removed in 4f3d5f2d87

The auth attempt rate limit is quite low (on purpose), so this can be a
common scenario where a user asks their admin to reset the limit instead
of waiting. We should provide a tool for administrators to handle such
requests without fiddling around with code in manage.py shell.
Calling `email.save()` is only needed if we altered `email.address`;
it is unnecessary if we called `email.users.add(...)` which will have
done its own INSERT.
This fixes two bugs: the most obvious is that there is a race where a
ScheduledEmail object could be observed in the window between creation
and when users are added; this is a momentary instance when the object
has no users, but one that will resolve itself.
The more subtle is that .save() will, if no records were found to be
updated, _re-create_ the object as it exists in memory, using an
INSERT[1]. Thus, there is a race with `deliver_scheduled_emails`
between when the users are added, and when `email.save()` runs:
1. Web request creates ScheduledEmail object
2. Web request creates ScheduledEmailUsers object
3. deliver_scheduled_emails locks the former, preventing updates.
4. deliver_scheduled_emails deletes both objects, commits, releasing lock
5. Web request calls `email.save()`; UPDATE finds no rows, so it
re-creates the ScheduledEmail object.
6. Future deliver_scheduled_emails runs find a ScheduledEmail with no
attending ScheduledEmailUsers objects
Wrapping the logical creation of both of these in a single transaction
avoids both of these races.
[1] https://docs.djangoproject.com/en/3.2/ref/models/instances/#how-django-knows-to-update-vs-insert
Only clear_scheduled_emails previously took a lock on the users before
removing them; make deliver_scheduled_emails do so as well, by using
prefetch_related to ensure that the table appears in the SELECT. This
is not necessary for correctness, since all accesses of
ScheduledEmailUser first access the ScheduledEmail and lock it; it is
merely for consistency.
Since SELECT ... FOR UPDATE takes an UPDATE lock on all tables
mentioned in the SELECT, merely doing the prefetch is sufficient to
lock both tables; no `on=(...)` is needed to `select_for_update`.
This also does not address the pre-existing potential deadlock from
these two use cases, where both try to lock the same ScheduledEmail
rows in opposite orders.
No codepath except tests passes in more than one user_profile -- and
doing so is what makes the deduplication necessary.
Simplify the API by making it only take one user_profile id.
This fixes a bug where email notifications were sent for wildcard
mentions even if the `enable_offline_email_notifications` setting was
turned off.
This was because the `notification_data` class incorrectly considered
`wildcard_mentions_notify` as an indeoendent setting, instead of a wrapper
around `enable_offline_email_notifications` and `enable_offline_push_notifications`.
Also add a test for this case.
While the STREAM_LINK_REGEX and STREAM_TOPIC_LINK_REGEX
identifies the stream and topic mentions in the content
correctly (tested by printing out the matches), the
stream/topic mentions are still not linked to the
corresponding streams/topics for imported messages, as
a `zulip_message` instance is required for linking these
mentions to actual streams/topics (see `StreamPattern`
class in `markdown/__init__.py`) which is not provided
while processing the markdown for imported messages.
This commit updates both the stream-level and realm-level message
retention setting to use 'unlimited' instead of 'forever' to set
message retention setting to "retain messages forever".
We incorrectly include many realm settings in the data section of
'realm/update_dict' schema. It should only contain the settings
related to message edit, realm icon, realm logo and authentication
methods and not other settings, becausea all the other settings send
'realm/update' event and not 'realm/update_dict' event.
This commit only removes 'message_retention_days' and others will
be removed separately.
Closes#19287
This endpoint allows submitting multiple addresses so we need to "weigh"
the rate limit more heavily the more emails are submitted. Clearly e.g.
a request triggering emails to 2 addresses should weigh twice as much as
a request doing that for just 1 address.
Previously, the output would make it look like we sent an actual email
to the first user in the dry_run output, which is very confusing.
The `dry_run` code path already prints all the accounts that would
have been emailed at the end, so there's no reason to have this line
before the dry_run check.
Additionally, we move after the `get_connection` check because
failures at that stage shouldn't result in logging an attempt to send
an email.
This way we can stop reading as soon as we get to the body. Also,
send an Accept header, check that the request was actually successful,
use lxml.etree.iterparse instead of a broken hand-rolled state
machine, and support XHTML, all for negative 28 lines of code.

While it should be an invariant that message.rendered_content is never
None for a row saved to the database, it is possible for that
invariant to be violated, likely including due to bugs in previous
versions of data import/export tools.
While it'd be ideal for such messages to be rendered to fix the
invariant, it doesn't make sense for this has_link migration to crash
because of such a corrupted row, so we apply the similar policy we
already have for rendered_content="".

Slack bot emails generated by us can be duplicate for two bots.
If such a case occur, append a counter to the email to make it
unique.
For maintaining the counter of duplicate emails and the final
email assigned to each bot, a class based approach is used with
static variables and static (class) methods. This keeps all the
data related to slack bot emails at the same place and easily
accessible from anywhere inside the module (without defining any
class object and passing it around).

These checks suffer from a couple notable problems:
- They are only enabled on staging hosts -- where they should never
be run. Since ef6d0ec5ca, these supervisor processes are only
run on one host, and never on the staging host.
- They run as the `nagios` user, which does not have appropriate
permissions, and thus the checks always fail. Specifically,
`nagios` does not have permissions to run `supervisorctl`, since
the socket is owned by the `zulip` user, and mode 0700; and the
`nagios` user does not have permission to access Zulip secrets to
run `./manage.py print_email_delivery_backlog`.
Rather than rewrite these checks to run on a cron as zulip, and check
those file contents as the nagios user, drop these checks -- they can
be rewritten at a later point, or replaced with Prometheus alerting,
and currently serve only to cause always-failing Nagios checks, which
normalizes alert failures.
Leave the files installed if they currently exist, rather than
cluttering puppet with `ensure => absent`; they do no harm if they are
left installed.
This is more efficient than get_lexer_by_name, since we don’t need to
instantiate the class just to get its name.

We added "user_settings" object containing all the user settings in
previous commit. This commit modifies the code to send the existing
setting fields in the top-level object only if user_settings_object
client_capabilities field is False.
This commit adds "user_settings_object" field to
client_capabilities which will be used to determine
if the client needs 'update_display_settings' and
'update_global_notifications' event.
We send a event with type 'user_settings' on updating user's display
and notification settings.
The old event types - 'update_global_notifications' and
'update_display_settings', are still supported for backwards
compatibility.
We do not require separate tests for checking events when changing
"enable_drafts_synchronization" as we already do this in the display
settings test because this setting is included in property_types.
Return zulip_merge_base alongside zulip_version
in `/register`, `/event` and `/server_settings`

clients.
These were added at some point in the past, but were not complete, and
it makes sense to document the current feature level as and when they
become available, since clients should not use the drafts endpoints on
older feature levels.
The main reason why this is needed is because this seems to be
convention and because we can't easily test event creation without
doing this.

This commit allows to import the following from rocketchat:
* All users
* All public/private channels
* All teams and its public/private channels
* All discussion rooms as topics in their parent channel
* All the messages in all the channels
* All private conversations
* Reactions on messages (except for custom emojis)
* Mentions in messages (except @all, @here mentions)
Previously, we checked for the `enable_offline_email_notifications` and
`enable_offline_push_notifications` settings (which determine whether the
user will receive notifications for PMs and mentions) just before sending
notifications. This has a few problem:
1. We do not have access to all the user settings in the notification
handlers (`handle_missedmessage_emails` and `handle_push_notifications`),
and therefore, we cannot correctly determine whether the notification should
be sent. Checks like the following which existed previously, will, for
example, incorrectly not send notifications even when stream email
notifications are enabled-
```
if not receives_offline_email_notifications(user_profile):
return
```
With this commit, we simply do not enqueue notifications if the "offline"
settings are disabled, which fixes that bug.
Additionally, this also fixes a bug with the "online push notifications"
feature, which was, if someone were to:
* turn off notifications for PMs and mentions (`enable_offline_push_notifications`)
* turn on stream push notifications (`enable_stream_push_notifications`)
* turn on "online push" (`enable_online_push_notifications`)
then, they would still receive notifications for PMs when online.
This isn't how the "online push enabled" feature is supposed to work;
it should only act as a wrapper around the other notification settings.
The buggy code was this in `handle_push_notifications`:
```
if not (
receives_offline_push_notifications(user_profile)
or receives_online_push_notifications(user_profile)
):
return
// send notifications
```
This commit removes that code, and extends our `notification_data.py` logic
to cover this case, along with tests.
2. The name for these settings is slightly misleading. They essentially
talk about "what to send notifications for" (PMs and mentions), and not
"when to send notifications" (offline). This commit improves this condition
by restricting the use of this term only to the database field, and using
clearer names everywhere else. This distinction will be important to have
non-confusing code when we implement multiple options for notifications
in the future as dropdown (never/when offline/when offline or online, etc).
3. We should ideally re-check all notification settings just before the
notifications are sent. This is especially important for email notifications,
which may be sent after a long time after the message was sent. We will
in the future add code to thoroughly re-check settings before sending
notifications in a clean manner, but temporarily not re-checking isn't
a terrible scenario either.

We incorrectly include many realm settings in the data section of

Instead of directly changing the `POST` attribute of a request, we
utilize the `HostRequestMock` initializer to produce requests with
different post data.
The decorators require the decorated function to be a valid view
function. This changes the way the mocked view functions and requests
are implemented such that we can invoke view functions without future
type errors.
`export_realm` accepts an HttpRequest as the first argument,
while `self.client_post` conflicts with it. Though the argument is
unused in `export_realm`, we keep it to be compliant with the
view function type.
As we only return the actual decorator as-is only if `function` is
`None`, we can use `@overload` to accurately annotate the return type
for the decorator.
When calling some functions or assigning values to certain attributes,
the arguments/right operand do not match the exact type that the
functions/attributes expect, and thus we fix that by converting types
beforehand.
Of the two other logging mocks left in this file, one checks
a logging call isn't made and another makes sure errors
aren't allowed by raising an exception as a side_effect
to the logger.
Cross realm bots will soon stop being a thing. This param is responsible

right way to handle the situation.
We will likely want to rename the `cross_realm_bots` section as well,
but that is a more involved API migration.
The code didn't account for existence of SOCIAL_AUTH_SUBDOMAIN. So the
redirects would happen to endpoints on the SOCIAL_AUTH_SUBDOMAIN, which

user came.
This fixes a batch of mypy errors of the following format:
'Item "None" of "Optional[Something]" has no attribute "abc"
Since we have already been recklessly using these attritbutes
in the tests, adding assertions beforehand is justified presuming
that they oughtn't to be None.
