We didn't have thumbnailing for images coming from data import and this
commit adds the functionality.
There are a few fundamental issues that the implementation needs to
solve.
1. The images come from an untrusted source and therefore we don't want
to just pass them through to thumbnailing without checking. For that
reason, we cannot just import ImageAttachment rows from the export
data, even for zulip=>zulip imports.
The right way to process images is to pass them to maybe_thumbail(),
which runs libvips_check_image() on them to verify we're okay with
thumbnailing, creates ImageAttachment rows for them and sends them
to the thumbnailing queue worker. This approach lets us handle both
zulip=>zulip and 3rd party=>zulip imports in the same way,
2. There is a somewhat circular dependency between the Message,
Attachment and ImageAttachment import process:
- ImageAttachments would ideally be created after importing
Attachments, but they need to already exist at the time of Message
import. Otherwise, the markdown processor doesn't know it has to add
HTML for image previews to messages that reference images. This would
mean that messages imported from 3rd party tools don't get image
previews.
- Attachments only get created after Message import however, due to the
many-to-many relationship between Message and Attachment.
This is solved by fixing up some data of Attachments pre-emptively, such
as the path_ids. This gives us the necessary information for creating
ImageAttachments before importing Messages.
While we generate ImageAttachment rows synchronously, the actual
thumbnailing job is sent to the queue worker. Theoretically, the worker
could be very backlogged and not process the thumbnails anytime soon.
This is fine - if the app is loaded and tries to display a message with
such a not-yet-generated thumbnail, the code in `serve_file` will
generate the thumbnails synchronously on the fly and the user will see
the image preview displayed normally. See:

This commit reformats hashed medium static avatar files("-medium.png"
files). Unlike user-uploaded avatar files, avatars served alongside
static files are hashed by Django. To implement the URL patterns for
finding medium-size avatar URLs that are hardcoded into current
versions of the mobile apps, the medium avatar files need to be
adjusted to include the "-medium" string just before the file type.
For example, the URL format will now be:
Before: welcome-bot-medium.123123321.png
After: welcome-bot.123123123-medium.png
This commit introduces an assertion to verify that the avatar file for
system bots exists and findable.
In development, it'll assert that the avatar file exists in the static
directory. This isn't done in production environment to avoid
unnecessary overhead. It helps verify that the protocol to fetch system
bot avatars still works when making changes during development.
In production it'll check if the avatar file exists in the STATIC_ROOT
and return a default avatar png if it doesn't.
Previously, requesting system bots URLs did not return any -medium.png
variants and SVG file was also used for notification bots' avatar, which
was problematic.
In this commit, the -medium.png variants is added for the avatars of
system bots and zulip-icon-square.svg is also converted into
notification-bot.png for the notification bot. The get_avatar_url method
has been updated to return the "medium" file variants for the system
bots.
Additionally, the system bots' avatar files is moved to a dedicated
directory to simplify the hashing logic for these files. Now, all files
in the "images/static_avatars/" directory will be hashed.
This commit makes sure system bots avatar files are hashed when served
as static files. This way, requests for these avatar files will be
served with long-lived caching headers by our nginx (see #22275).
We don't need to worry about stale caches for these files because they
will only be used by system bots.
Fixes#31458.
This makes a Zulip server more isolated than relying on gravatar, and
avoids complex logistics if in the future we move system bots to live
inside individual realms.

This commit adds support to add subgroups to a group while
creating it.
User can add the subgroups to group irrespective of permissions
like user can add members during creating it.
This commit updates code to allow users with permission
to add members to add subgroups as well. And only users
with permission to manage the group can remove subgroups.
Also updated tests to check permissions in separate tests
and removed them from the existing test.
Users with permission to manage the group have all the permissions
including joining/leaving the group, adding others group which also
have a separate setting to control them.
So, it makes sense to just check managing permissions first in
access_user_group_for_update and then check the specific permission.
There is no behavioral change in this commit, it only changes the
order of checking permissions.
The main change is redefining ALLOW_GROUP_VALUED_SETTINGS to not
control code, but instead to instead control the configuration for
whether settings that have not been converted to use our modern UI
patterns should require system groups.
Fundamentally, it's the same for the realm/stream group-valued
settings, which don't have the new UI patterns yet.
We remove the visual hiding of the "can manage group" setting, which
was hidden only due to transitions being incomplete.
'realm_upload_quota_mib` is updated when `plan_type` changes.
Earlier, we were including 'upload_quota' to update
`realm_upload_quota_mib` in extra_data field of 'realm op: update'
event format when property='plan_type'.
This commit migrate those two parameters to `realm op: update_dict`
event format.
* None of the clients processes these fields, so no compatibility
code required.
* Renamed `upload_quota` to `upload_quota_mib` as it better aligns
with our goal to encode units in the client-facing API names.
Also, it helps to avoid extra code to update 'realm_upload_quota_mib`
in web client, web client simply aligns with
'realm["realm_" + key] = value'.
Earlier we use to restrict admins, moderators or members of a group to
manage that group if they were part of the realm wide
`can_manage_all_groups`. We will not do that anymore and even
non-members of a group regardless of role can manage a group if they are
part of `can_manage_all_groups`.
See
https://chat.zulip.org/#narrow/stream/101-design/topic/Group.20add.20members.20dropdown/near/1952902
to check more about the migration plan for which this is the last step.
Removing members will be controlled by `can_manage_group` until we add
`can_remove_members_group` in the future.
Users with permission to manage a group can add members to that group by
default without being present in `can_add_members_group`.
Earlier, only public data export was possible via `POST /export/realm`
endpoint. This commit adds support to create full data export with
member consent via that endpoint.
Also, this adds a 'export_type' parameter to the dictionaries
in `realm_export` event type and `GET /export/realm` response.
Fixes part of #31201.
Document setting the keys that will send a message or create a new
line when composting a message via the compose box and via the
personal settings overlay.
Updates links and redirect from former help center article about
this feature.
Fixes#31620.
This commit updates backend code to not allow adding deactivated
users to groups including when creating groups and also to not
allow removing deactivated users from groups.
There is no behavioral changes to deactivated users as we do
not create UserMessage rows or call the notification code path
for deactivated users in a user group mention. But it is better
to not include the deactivated users in fields like
"mention_user_ids", so this commit updates the code to not
include deactivated users in the computed mention data.
This commit updates code to not include deactivated users in the
anonymous group settings data sent to clients, where the setting
value is sent as a dict containing members and subgroups of the
anonymous group.
This commit updates code to not include deactivated users in
members list in the user groups object sent in "/register"
and "GET /user_groups" response and also in the response
returned by endpoint like "GET /user_groups/{group_id}/members".
The events code is also update to handle this -
- We expect clients to update the members list on receiving
"realm_user/update" event on deactivation. But for guests
who cannot access the user, "user_group/remove_members"
event is sent to update the group members list on deactivation.
- "user_group/add_members" event is sent to all the users on
reactivating the user.
We previously did not update the subscribers list for unsubscribed
and never subscribed streams when a user is deactivated or a
guest user loses access to some user.
We show a confirmation dialog explaining the "resolve topics"
feature when the user marks a topic resolved for the first time.
If the user confirms the action, we mark the
topic resolved, else we don't.
We don't show anything the first time a topic is marked
unresolved.
Fixes#31242
Limiting lookups by delivery_email to users with "everyone" email
visibility is overly simplistic. We can successfully do these lookups
whenever the requester has the permission to view the real email address
of the user they're looking up.
This is helpful for taking an "acting user" and getting the list of
email_address_visibility values such that the UserProfiles with those
values of the setting permit the acting user to view their
deliver_email.
This can be used for a query "all users whose delivery_email is viewable
by <requester>" in an upcoming commit.
The added code is ugly, but at least it lets us simplify some similarly
ugly logic in can_access_delivery_email.
Earlier, we were sending 'delete_message' event to all active
subscribers of the stream.
We shouldn't send event to those users who don't have access
to the deleted message in a private stream with protected history.
This commit fixes that bug.
Also, now we use 'event_recipient_ids_for_action_on_messages'.
It helps to add hardening such that if the invariant "no usermessage
row corresponding to a message exists if the user loses access to the
message" is violated due to some bug, it has minimal user impact.
Earlier, we used to store the key data related to realm exports
in RealmAuditLog. This commit adds a separate table to store
those data.
It includes the code to migrate the concerned existing data in
RealmAuditLog to RealmExport.
Fixes part of #31201.
This commit updates code to store the realm export stats in
json format instead of plain text.
This will help in storing the stats as JsonField in RealmExport table.
Because the main indexes on end_time either don't include realm_id or
do include subgroup, passing an explicit subgroup=None for
single-realm queries to read CountStats that don't use the subgroups
feature greatly improves the query plans.
We create an unnamed user group with just the group creator as it's
member when trying to set the default. The pattern I've followed across
most of the acting_user additions is to just put the user declared
somewhere before the check_add_user_group and see if the test passes.
If it does not, then I'll look at what kind of user it needs to be set
to `acting_user`.
This commit does not add the logic of using this setting to actually
check the permission on the backend. That will be done in a later
commit.
Only owners can modify this setting, but we will add that logic in a
later commit in order to keep changes in this commit minimal.
Adding the setting breaks the frontend, since the frontend tries to find
a dropdown widget for the setting automatically. To avoid this, we've
added a small temporary if statement to `settings_org.js`.
Although, most lists where we insert this setting follow an unofficial
alphabetical order, `can_manage_all_groups` has been bunched together
with `can_create_groups` since keeping those similar settings together
would be nicer when checking any code related to creating/managing a
user group.
