This commit renames "can_edit_topic_of_any_message" function
in models.py to "can_move_messages_to_another_topic" and
"user_can_edit_topic_of_any_message" function in settings_data.js
to "user_can_move_messages_to_another_topic".
This change is done since topic editing permission does not
depend on message sender now and messages are considered same
irrespective of whether the user who is editing the topic had sent
the message or not. This also makes the naming consistent with
what we use for the label of this setting in webapp and how we
describe this action in help documentation.
This explicitly enforces ordering on the linkifiers. This is useful when
there are overlapping linkifier patterns that matches the same text. In
our current linkifier implementation, this order affects how the
patterns are handled in the markdown processor, with the earlier ones
being prioritized.

This allows us to revoke MultiUseInvites by changing their .status

information on PreregistrationUsers about which MultiUseInvite they came
from).
Fixes#23517.
While this feature was added to Zulip very early, it has been troubled
for most of that time; it never looked great visually, had a lot of
implementation complexity around resize.js, and has a weird model (a
setting that changes the UI only in certain window sizes).
This option is not commonly used; while a significant portion of users
have it enabled, many of them just don't use window sizes where it
actually has an effect. So it's not clear that it will be missed if
removed; we got very few bug reports when it was completely broken for
a few days after we first integrated the new left sidebar private
messages design.
Even with it no longer being broken, it does not work very well with
the addition of the new PMs section in the left sidebar. (Having two
scrollbars in the sidebar looks quite awkward.) The new private
messages section in the left sidebar also addresses some of the use
cases for always keeping the Users list always visible, even in narrow
windows.
This option is only removed from frontend for now. To make this
decision easily reversible, the backend code of this feature
is still kept.
Storing a QuerySet rather than the list version of the result in it
has a large overhead -- and, as noted by the type annotations, the
result is only ever used as a list. This difference is particularly
important because the cached `get_realm_user_dicts` can get extremely
large for realms with large numbers of users, potentially overflowing
the 1MB default object limit in memcached.
Switch all cases of `cache_with_key` which return QuerySets to
returning the list values of them.
These were useful as a transitional workaround to ignore type errors
that only show up with django-stubs, while avoiding errors about
unused type: ignore comments without django-stubs. Now that the
django-stubs transition is complete, switch to type: ignore comments
so that mypy will tell us if they become unnecessary. Many already
have.

Previously, we type the model fields with explicit type annotations

stubs. This allows mypy to infer the types of the model fields for us.

Previously, we included all three message edit related settings
("allow_message_editing", "message_content_edit_limit_seconds" and
"edit_topic_policy") in the event data and api response irrespective
of which of these settings were changed. Now, we only include changed
settings and separate events are sent for each setting if more than
one of them is changed.
Note that the previous typed in event_schema.py for
`message_content_edit_limit_seconds` incorrectly did not allow `None`
as a value, which is used to encode no limit.

SCIMClient is a type-unsafe workaround for django-scim2’s conflation
of SCIM users with Django users. Given that a SCIMClient is not a
UserProfile, it might as well not be a model at all, since it’s only
used to satisfy django-scim2’s request.user.is_authenticated queries.
This doesn’t solve the type safety issue with assigning a SCIMClient
to request.user, nor the performance issue with running the SCIM
middleware on non-SCIM requests. But it reduces the risk of potential
consequences worse than crashing, since there’s no longer a
request.user.id for Django to confuse with the ID of an actual
UserProfile.

Previously, an active production Zulip server would experience a class
of deadlocks caused by two or more concurrent bulk update operations
on the UserMessage table.
This is because UPDATE ... SET ... WHERE statements that execute in
parallel take row-level UPDATE locks as they get results; since the
query plans may result in getting rows in different orders between two
queries, this can result in deadlocks.
Some databases allow ORDER BY on their UPDATE ... WHERE statements;
PostgreSQL does not. In PostgreSQL, the answer is to do a sub-select
with an ORDER BY ... FOR UPDATE to ensure consistent ordering on row
locks.
We do this all code paths using bitand or bitor as part of bulk
editing message flags, which should ensure that these concurrent
operations obtain row level locks on the table in the same order.

In places where the callee evaluates the `_StrPromise` object in all

`JsonableError` that ends up handled by the error handler middleware,
and `internal_send_stream_message` that depends on `check_stream_topic`,
requiring the `topic` to be evaluated anyway. In other siuations, the

We want to tie the prereg_user to the MultiUseInvite directly rather

Confirmation object, creating a confirmation link (via
create_confirmation_link) to which then the user is redirected to finish
account creation. This means that the PreregistrationUser is already

This is necessary for the migration 0386_fix_attachment_caches to run,
and likely makes more convenient any future parallel code interacting
with both Attachment and ArchivedAttachment.
Previously, Attachment.is_realm_public and its cousin,
Attachment.is_web_public, were properties that began as False and
transitioned to True only when a message containing a link to the
attachment was sent to the appropriate class of stream, or such a link
was added as part of editing a message.
This pattern meant that neither field was updated in situations where
the access permissions for a message changed:
* Moving the message to a different stream.
* Changing the permissions for a stream containing links to the message.
This correctness issue has limited security impact, because uploaded
files are secured both by a random URL and by these access checks.
To fix this, we reformulate these fields as a cache, with code paths
that change the permissions affecting an attachment responsible for
setting these values to the `None` (uncached) state. We prefer setting
this `None` state over computing the correct permissions, because the
correct post-edit permissions are a function of all messages
containing the attachment, and we don't want to be responsible for
fetching all of those messages in the edit code paths.
he possibility for it being null was likely an oversight -- it should
have been removed after the early migrations to backfill the field
when it was added.
We've confirmed there are no existing violations of this invariant in
Zulip Cloud.
This commit creates a new TypedDict RealmPlaygroundDict for realm
playground objects. Now the list of playgrounds in the events sent
to clients and the "added_playground" field of RealmAuditLog entry
use RealmPlaygroundDict instead of Dict.
This is in a separate commit to make deployment easier. It ensures that
this is only marked non-null after the backfill migration (backfilling
.uuid for all old UserProfiles) runs - which was added in the previous
commit.
This will make it convenient to add a handful of organizations to the
beta of this feature during its first few weeks to try to catch bugs,
before we open it to everyone in Zulip Cloud.
The correct return type of get_realm_domains should
be List[Dict[str, Union[bool, str]]] instead of
List[Dict[str, str]] because allowed_subdomains is
a bool field not str.
This model is by designed intended to exist on a 1:1 relationship with
Realms, and we attempt to ensure that with application code, but we
should have a unique constraint too, since a database with duplicate
such entries would be corrupted.
We do this via the standard Django OneToOneField.
The database value for expiry_date is None for the invite
that will never expire and the clients send -1 as value
in the API similar to the message retention setting.
Also, when passing invite_expire_in_days as an argument
in various functions, invite_expire_in_days is passed as
-1 for "Never expires" option since invite_expire_in_days
is an optional argument in some functions and thus we cannot
pass "None" value.
In English, compound adjectives should essentially always be
hyphenated. This makes them easier to parse, especially for users who
might not recognize that the words “web public” go together as a

The change to curl_param_value_generators.py warrants a brief
explanation. Stream permission changes now generate a notification
message. Our curl example test for removing a reaction comes after
the two tests for updating the stream permission changes, thus the
hardcoded message ID in that test needs to be incremented by 2 to
account for the two notification messages that now come before it.
This is a part of #20289.
An explanatory note on the changes in zulip.yaml and
curl_param_value_generators is warranted here. In our automated
tests for our curl examples, the test for the API endpoint that
changes the posting permissions of a stream comes before our
existing curl test for adding message reactions.
Since there is an extra notification message due to the change in
posting permissions, the message IDs used in tests that come after
need to be incremented by 1.
This is a part of #20289.
We now make it mandatory to pass in the Realm object.
If this function was ever called with None, I am scared

https://chat.zulip.org/#narrow/stream/378-api-design/topic/still_url/near/1302573

opening a link to a doc with an outdated Django version would show a

Most of these links are inside comments.
Following the replacement of these links in our docs, this commit uses
a search with the regex "docs.djangoproject.com/en/([0-9].[0-9]*)/"

Supporting URL percent-encoded bytes is possible using `%%20`, but this
is not necessarily very understandable to end-users, even those that
understand percent encoding.
Allow `%20` in linkifier URL format strings, and transform them into
`%%20` in the pattern just before they are applied in markdown
translation. Care must be taken here, such that already-escaped `%`s
are not escaped an extra time.
We do this before rendering, and not before storage, as
a simplification; the JS-side linkifier at present only understands
`%(foo)s` and thus needs no changes, and to avoid an un-escaping pass
before showing in the admin UI.
User-supplied custom realm filter has had some sort of regex-based
validation of the format URL since their introduction in
d7e1e4a2c0 -- and this has always been
in addition to the URLValidator. The URLValidator is the one which
does the security-relevant work of validating that the schema is
reasonable, and that the overall shape of the URL is well-formed. The
regex has served primarily to arbitrary limit the characters that can
appear in the URL, in the mistaken name of safety.
Adjust the regex, such that its only purpose is to verify that the
usages of `%` characters in the URL are reasonable, and leave the URL
validation to the URLValidator, which can do a far better job. This
includes broadening the support to include `%%` as an escape
character; this is likely such a niche case as to be unnecessary, but
costs little.

This commit adds related_name parameter to UserGroup.direct_members

This commit also sets related_name of UserGroupMembership.user_group
and UserGroupMembership.user_profile to "+" which means that we will
not be having backward relations for these. This change is correct
since we would need to use the recursive queries to get all the
groups of a user and all the members of a group after we add the
subgroups concept in next commit. This leads to us using direct_members
field of UserGroup instead of usergroupmembership_set in mention code,
but this will soon be replaced with the recursive query function to
include subgroup's members as well.

Zulip attempts to validate that the regular expressions that admins
enter for linkifiers are well-formatted, and only contain a specific
subset of regex grammar. The process of checking these
properties (via a regex!) can cause denial-of-service via
backtracking.
Furthermore, this validation itself does not prevent the creation of
linkifiers which themselves cause denial-of-service when they are
executed. As the validator accepts literally anything inside of a
`(?P<word>...)` block, any quadratic backtracking expression can be
hidden therein.
Switch user-provided linkifier patterns to be matched in the Markdown
processor by the `re2` library, which is guaranteed constant-time.
This somewhat limits the possible features of the regular
expression (notably, look-head and -behind, and back-references);
however, these features had never been advertised as working in the
context of linkifiers.
A migration removes any existing linkifiers which would not function
under re2, after printing them for posterity during the upgrade; they
are unlikely to be common, and are impossible to fix automatically.
The denial-of-service in the linkifier validator was discovered by
@erik-krogh and @yoff, as GHSL-2021-118.
Users wanted a feature where they could specify
which users can create public streams and which users can
create private streams.
This splits stream creation code into two parts,
public and private stream creation.
Fixes#17009.
This commit replaces 'allow_message_deleting' boolean setting
with an integer setting 'delete_own_message_policy'. We have a
separate dropdown now for deciding which user-roles can delete
messages sent by themselves and the time-limit setting droddown
is different.
This new setting has two options - everyone and admins only. Other
options including moderators will be added further.
We also remove the "Never" option from the original time-limit
dropdown, as admins are always allowed to delete message. This
never option resembled the case of only admins being allowed to
delete but this state is now resembled by setting the dropdown
to "admins only" and we also disable the time-limit dropdown in
this case as admins are allowed to delete irrespective of limit.
Note, this setting is only for deleting messages sent by the
deleting user themselves, and only admins are allowed to delete
messages sent by others as before.
We make zero invalid value for message_content_delete_limit_seconds and
for handling the case of "Allow to delete message any time", the API-level
value of message_content_delete_limit_seconds is "anytime" and "None"
as the DB-level value. We also use these values for message retention
setting, so it helps maintain consistency.
This is a somewhat subtle function, that deserves a few comments
explaining subtle details of its logic, and there's no good reason to
have multiple copies of that logic that are slightly inconsistent.
Because the main changes here are just checking for invariant
failures, the behavioral change here should be limited to ensuring
deactivated streams are not considered available even if they were
tagged as web public streams before deactivation.
This commit removes the existing default_twenty_four_hour_time field in
Realm table which was used to set the twenty_four_hour_time setting of
new user on joining and instead we now use the twenty_four_hour_time
field of RealmUserDefault table for the same.
With some tweaks by tabbott to clarify the documentation.
These values are currently either a string already or a List[int]. We
should do the conversion in
do_update_user_custom_profile_data_if_changed properly: if the value is
already a string, it can be used directly - if it's not, orjson.dumps is
a more future-proof way of converting than str(). Using orjson.dumps
here also allows us to change the converter of the USER type
CustomProfileField to orjson.loads, which is nicer to have than
ast.literal_eval.
While orjson.dumps() and str() give the same output when
given the special case of List[int],
ast.literal_eval was previously used due to orjson.loads not being
a good inverse function to str in general. That gets straightened out
now.
None of the existing custom profile field types have the value as an
integer like declared in many places - nor is it a string like currently
decalred in types.py. The correct type is Union[str, List[int]]. Rather
than tracking this in so many places throughout the codebase, we add a
new ProfileDataElementValue type and insert it where appropriate.
This new setting both serves as a guard to allow us to merge API
support for web public streams to main before we're ready for this
feature to be available on Zulip Cloud, and also long term will
protect self-hosted servers from accidentally enabling web-public
streams (which could be a scary possibility for the administrators of
a corporate Zulip server).
This is a follow-up to #19388.
We will in the future allow patch requests to change the visibility
of an existing topic, so `last_updated` is better name for this field.
This commit does not affect the API or events in any way, but only the
database.
Now, when we add a custom animated emoji to the realm
we also save a still image of it (1st frame of the gif). So
we can avoid showing an animated emoji every time.
This extends the invite api endpoints to handle an extra
argument, expiration duration, which states the number of
days before the invitation link expires.
For prereg users, expiration info is attached to event
object to pass it to invite queue processor in order to
create and send confirmation link.
In case of multiuse invites, confirmation links are
created directly inside do_create_multiuse_invite_link(),
For filtering valid user invites, expiration info stored in
Confirmation object is used, which is accessed by a prereg
user using reverse generic relations.
Fixes#16359.
This commit adds do_set_realm_user_default_setting which
will be used to change the realm-level defaults of settings
for new users.
We also add a new event type "realm_user_settings_defaults"
for these settings and a "realm_user_settings_default" object
in '/register' response containing all the realm-level default
settings.
This was likely initiall created with null=True in
5c5ffd6ea3 just because we didn't have a
plan for backfilling this field, but I verified that Zulip Cloud has
no realms without a name set, and that's the place most likely to have
any form of super-legacy nameless realms.
So we can clean up this aspect of the data model without a special
migration to do something with existing realms with name=None (which I
suspect would have resulted in a 500 anyway).
This fixes a regression where one could end up deactivating all owners
of a realm when trying to synchronize LDAP with the `is_realm_admin`
flag configured in `AUTH_LDAP_USER_FLAGS_BY_GROUP`.
With tweaks by tabbott to add is_moderator as well.
Fixes#18677.
