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:
1b47134d0d/zerver/views/upload.py (L333-L342)
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.
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`.
For exporting full with consent:
* Earlier, a message advertising users to react with thumbs up
was sent and later used to determine the users who consented.
* Now, we no longer need to send such a message. This commit
updates the logic to use `allow_private_data_export` user-setting
to determine users who consented.
Fixes part of #31201.
Renamed event types below in the enum class to use channel instead of
stream.
Event types moved: STREAM_CREATED, STREAM_DEACTIVATED, STREAM_NAME_CHANGED
STREAM_REACTIVATED, STREAM_MESSAGE_RETENTION_DAYS_CHANGED
STREAM_PROPERTY_CHANGED, STREAM_GROUP_BASED_SETTING_CHANGED
The export tool was only exporting the already-thumbnailed emoji file,
omitting the original one. Now we make sure to export the .original file
too, like we do for avatars, and make the import tool process it
directly, to thumbnail it directly and generate a still in the case of
animated emojis.
Otherwise, the imported realm wouldn't have the <emoji>.png.original
file that we generally expect to have accessible, and stills for
animated emojis were completely missing.
Instead of the PUSH_NOTIFICATIONS_BOUNCER_URL and
SUBMIT_USAGE_STATISTICS settings, we want servers to configure
individual ZULIP_SERVICE_* settings, while maintaining backward
compatibility with the old settings. Thus, if all the new
ZULIP_SERVICE_* are at their default False value, but the legacy
settings are activated, they need to be translated in computed_settings
to the modern way.
This commit renames the "Huddle" Django model class to
"DirectMessageGroup", while maintaining the same table --
"zerver_huddle".
Fixes part of #28640.
Hash the salt, user-id, and now avatar version into the filename.
This allows the URL contents to be immutable, and thus to be marked as
immutable and cacheable. Since avatars are served unauthenticated,
hashing with a server-side salt makes the current and past avatars not
enumerable.
This requires plumbing the current (or future) avatar version through
various parts of the upload process.
Since this already requires a full migration of current avatars, also
take the opportunity to fix the missing `.png` on S3 uploads (#12852).
We switch from SHA-1 to SHA-256, but truncate it such that avatar URL
data does not substantially increase in size.
Fixes: #12852.
This commit performs a sweep on the first batch of non API
files to rename "huddle" to "direct_message_group`.
It also renames variables and methods of type -
"huddle_message" to "group_direct_message".
This is a part of #28640
Fixes#26369.
There are two important fixes to make to the dicts in edit_history:
1. Update the user_id so that it points to the imported sender.
2. Apply fix_message_rendered_content to the prev_rendered_content data
to fix up mentions and other such syntax.
When importing a Stream, UserProfiles don't yet exist. so trying to
import stream.creator fails with something like:
```
psycopg2.errors.ForeignKeyViolation: insert or update on table
"zerver_stream" violates foreign key constraint
"zerver_stream_creator_id_65aeba7e_fk_zerver_userprofile_id"
DETAIL: Key (creator_id)=(5) is not present in table "zerver_userprofile".
```
The reactions added to messages in the test database are
random in nature, so there is a possibility of any number
of reaction records in the exported user data.
The test now verifies the reaction which was added in the test
itself.
Earlier, the test was assuming the reaction added in the test
is the only record in the exported data.
That would result in a flaky behavior. This commit fixes the
flaky behavior.
When the export is NOT generated by another zulip server,
while importing:
* Set the 'zulip_update_announcements_level' to the latest level
as we don't want to send all the older update messages to them.
* Send a group DM to admins, suggesting them to configure the
stream in order to avoid missing future update messages.
Fixes#29041.
This commit removes name, description, is_system_group and
can_mention_group fields from UserGroup model and rename
them in NamedUserGroup model.
Fixes#29554.
Replaced HUDDLE attribute with DIRECT_MESSAGE_GROUP using VS Code search,
part of a general renaming of the object class.
Fixes part of #28640.

Only affects zulipchat, by being based on the BILLING_ENABLED setting.
The restricted backends in this commit are
- AzureAD - restricted to Standard plan
- SAML - restricted to Plus plan, although it was already practically
restricted due to requiring server-side configuration to be done by us
This restriction is placed upon **enabling** a backend - so
organizations that already have a backend enabled, will continue to be
able to use it. This allows us to make exceptions and enable a backend
for an org manually via the shell, and to grandfather organizations into
keeping the backend they have been relying on.
This leads to significant speedups. In a test, with 100 random unique
event classes, the old code processed a batch of 100 rows (on average
66-ish unique in the batch) in 0.45 seconds. Doing this in a single
query processes the same batch in 0.0076 seconds.
This is preparatory work towards adding a Topic model.
We plan to use the local variable name as 'topic' for
the Topic model objects.
Currently, we use *topic as the local variable name for
topic names.
We rename local variables of the form *topic to *topic_name
so that we don't need to think about type collisions in
individual code paths where we might want to talk about both
Topic objects and strings for the topic name.
This commit creates a RealmAuditlog entry with a new event_type
'RealmAuditLog.REALM_IMPORTED' after the realm is reactivated.
It contains user count data (using realm_user_count_by_role)
stored in extra_data.
This helps to have an accurate user count data for the billing
system if someone tries to signup just after doing an import.
