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
Currently, we want to ask users if they would like to delete their
attachments after they have removed the attachments while editing. These
changes are preparatory changes on the backend to return a list of removed
attachments after the user has removed attachments while editing.
Fixes part of #25525.
As guest users are charged at a different rate on Zulip Cloud, it
makes sense to track these changes in our LicenseLedger table so
that we can have an accurate record of the use of licenses that
a realm has purchased.
We used 'savepoint=False' in #31169 which was prior to our discussion
in CZO to use 'durable=True' instead.
This commit makes changes to use 'durable=True' in the outermost
transaction.atomic block.
This commit removes the 'prev_rendered_content_version'
field from:
* the 'edit_history' object within message objects in the
API response of `GET /messages`, `GET /messages/{message_id}`
and `POST /zulip-outgoing-webhook`.
* the 'update_message' event type
as it is an internal server implementation detail not used
by any client.
Note: The field is still stored in the 'edit_history' column
of the 'Message' table as it will be helpful when making
major changes to the markup rendering process.
Thumbnails are usually enqueued in the worker when the image is
uploaded. However, for images which were uploaded before the
existence of the thumbnailing worker, and whose metadata was
backfilled (see previous commit) this leaves a permanent spinner,
since nothing triggers the thumbnail worker for them.
Enqueue a thumbnail worker for every spinner which we render into
Markdown. This ensures that _something_ is attempting to resolve the
spinner which the user sees. In the case of freshly-uploaded images
which are still in the queue, this results in a duplicate entry in the
thumbnailing queue -- this is harmless, since the worker determines
that all of the thumbnails we need have already been generated, and it
does no further work. However, in the case of historical uploads, it
properly kicks off the thumbnailing process and results in a
subsequent message update to include the freshly-generated thumbnail.
While specifically useful for backfilled uploads, this is also
generally a good safety step for a good user experience, as it also
prevents dropped events in the queue from unknown causes from leaving
perpetual spinners in the message feed.
Because `get_user_upload_previews` is potentially called twice for
every message with spinners (see 6f20c15ae9), we add an additional
flag to `get_user_upload_previews` to suppress a _second_ event from
being enqueued for every spinner generated.
Since each loop may add more than one file to the `storage_paths`
list, this may result in more than 1000 files being sent to
delete_message_attachments. Since the S3 backend only supports 1000
elements being deleted at once, we must partition the list into chunks
which are no more than 1000 elements long.
There are a few places where we want to set the max invites for a
realm to the default for a realm's plan type, so this creates a
helper function that can be used consistently to get that default
value.
Adds some validation for changing the realm's max invites via the
support view so that it is not set below the default max for the
realm's plan type, and so that if it's currently set to the default
max it's not reset to that same value.

This commit updates the db transaction to be durable for
do_update_user_custom_profile_data_if_changed to avoid
addition of any outer atomic block.
While adding any outer atomic block this will raise a runtime error
and we can replace the durable argument with 'savepoint=False'
otherwise we'll have to manually track down the action functions
getting called in that outer atomic block and set the savepoint=False
otherwise it'll lead to creation of savepoints which we don't want.
We can't set savepoint=False before hand to the outermost action
function because it leads to rollback of transaction in tests when
an error is raised in action function.

Messages are rendered outside of a transaction, for performance
reasons, and then sent inside of one. This opens thumbnailing up to a
race where the thumbnails have not yet been written when the message
is rendered, but the message has not been sent when thumbnailing
completes, causing `rewrite_thumbnailed_images` to be a no-op and the
message being left with a spinner which never resolves.
Explicitly lock and use he ImageAttachment data inside the
message-sending transaction, to rewrite the message content with the
latest information about the existing thumbnails.
Despite the thumbnailing worker taking a lock on Message rows to
update them, this does not lead to deadlocks -- the INSERT of the
Message rows happens in a transaction, ensuring that either the
message rending blocks the thumbnailing until the Message row is
created, or that the `rewrite_thumbnailed_images` and Message INSERT
waits until thumbnailing is complete (and updated no Message rows).

Previously, if someone changed the font-size or line height
settings to some value other than the legacy values, we set
dense_mode to False if it was True. This commit changes the
code to require clients to pass dense_mode as False in such
cases and raise an error otherwise.
We should flush the cache after commiting changes to DB to
make sure that the cache does not contain stale data when
updating multiple settings in a single request.
A new table is created to track which path_id attachments are images,
and for those their metadata, and which thumbnails have been created.
Using path_id as the effective primary key lets us ignore if the
attachment is archived or not, saving some foreign key messes.
A new worker is added to observe events when rows are added to this
table, and to generate and store thumbnails for those images in
differing sizes and formats.
We thumbnail and serve emoji with the same format as they were
uploaded. However, we preserved the original extension, which might
mismatch with the provided content-type.
Limit the content-type to a subset which is both (a) an image format
we can thumbnail, and (b) a media format which is widely-enough
supported that we are willing to provide it to all browsers. This
prevents uploading a `.tiff` emoji, for instance.
Based on this limited content-type, we then reverse to find the
reasonable extension to use when storing it. This is particularly
important because the local file storage uses the file extension to
choose what content-type to re-serve the emoji as.
This does nothing for existing emoji, which may have odd or missing
file extensions.
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 fixes the bug where the "topic unresolved" notification
is wrongly triggered when moving a message between a resolved and
unresolved topic, except for when the topics have the same name.
To resolve this issue, the commit ensures that resolved/unresolved
notifications are not sent if a message has been moved to a new
topic. This is achieved by comparing the names of the old and new
topics without considering the "resolved prefix".
The commit also accounts for the scenario where `new_topic_name`
has been truncated, indicating that it was resolved and the name
had to change to accommodate the "resolved prefix".
This solution does not try to specially handle the possible case that
a stream has two topics with the same name, even if one is resolved
and another unresolved.
Fixes#29007.
This commit updates the code so that only the moved notification is
triggered when moving a message between a resolved and unresolved
topic in different streams or when moving a topic itself.
This change takes place even when both stream change and resolve
or unresolve a topic takes place in the same API request, as we
now consider it only a move operation.
This fixes a case where a message is moved between topics that
have the same name, but one resolved and another unresolved and
in different streams. Previously a resolved or unresolved
notification would also be sent. Now, this will not happen,
ensuring only the move operation is notified.
Fixes part of #29007.
Previously, when a referrer's invitation to Zulip was accepted,
they got a notification from notification-bot indicating

Fixes: #20398
To improve onboarding experience following onboarding
messages are marked as starred:
* First message in each onboarding topic.
* Initial DM sent by Welcome bot
Note: The onboarding topic messages needs to be tracked
in 'OnboardingUserMessage' model to get starred.
Fixes#29298.
We give the user some messages in their feed, so that they can
learn how to use the home view in a realistic way.
For realms having older onboarding messages, we mark the very
most recent messages as unread.
This commit updates the logic to ONLY mark the tracked onboarding
messages (if present) i.e. messages tracked in 'OnboardingUserMessage'
as unread.
Fixes part of #29298.
This prep commit reorders code blocks in 'do_create_user'
to call the function 'send_initial_realm_messages' before
'process_new_human_user'.
This is required because for the first user (who creates realm)
we need to send the onboarding messages before adding message
history (performed by process_new_human_user) otherwise messages
won't be starred as required.
This commit also takes care of NOT marking the onboarding
messages as 'historical' for the realm creator.
This commit adds the missing historical flag to recent
messages added in a new user's feed.
Reason:
* User didn't receive when they were sent, so semantically
the 'historical' flag should be present.
* It helps to avoid the "You (un)subscribed to.." bookend
while reading older messages.
The bookend appears whenever the historical flag flips
between adjacent messages. Earlier, the bookend was visible
between 'recent messages' and 'older messages'. This makes
sure that the bookend is visible only at the moment new
message is sent by the user after account creation.
This commit renames the constants:
MAX_NUM_ONBOARDING_MESSAGES to MAX_NUM_RECENT_MESSAGES
MAX_NUM_ONBOARDING_UNREAD_MESSAGES to MAX_NUM_RECENT_UNREAD_MESSAGES
ONBOARDING_RECENT_TIMEDELTA to RECENT_MESSAGES_TIMEDELTA
The term 'onboarding' is preffered to be used for the
new messages sent during realm creation or new user creation.
These constants are related to already present recent messages.
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
Earlier, a one-time 'visibility_policy_banner' was displayed to
existing as well as new users to inform them about the new
"follow/unmute topics" feature.
It makes sense to educate only the existing Zulip users about
the new feature using this banner. New users don't need to know
about following topics right away.
This commit makes changes to NOT show the banner to new users.
This will also help to avoid banner overload in the new user
experience.
Fixes#30615.
Creates a new "realm_deactivated" email that can be sent to realm
owners as part of `do_deactivate_realm`, via a boolean flag,
`email_owners`.
This flag is set to `False` when `do_deactivate_realm` is used for
realm exports or changing a realm's subdomain, so that the active
organization owners are not emailed in those cases.
This flag is optional for the `deactivate_realm` management command,
but as there is no active user passed in that case, then the email
is sent without referencing who deactivated the realm.
It is passed as `True` for the support analytics view, but the email
that is generated does not include information about the support
admin user who completed the request for organization deactivation.
When an active organization owner deactivates the organization, then
the flag is `True` and an email is sent to them as well as any other
active organization owners, with a slight variation in the email text
for those two cases.
Adds specific tests for when `email_owners` is passed as `True`. All
existing tests for other functionality of `do_deactivate_user` pass
the flag as `False`.
Adds `localize` from django.util.formats as a jinja env filter so
that the dates in these emails are internationlized for the owner's
default language setting in the "realm_deactivated" email templates.
Fixes#24685.
This is done in as much of a drop-in fashion as possible. Note that
libvips does not support animated PNGs[^1], and as such this
conversion removes support for them as emoji; however, libvips
includes support for webp images, which future commits will take
advantage of.
This removes the MAX_EMOJI_GIF_SIZE limit, since that existed to work
around bugs in Pillow. MAX_EMOJI_GIF_FILE_SIZE_BYTES is fixed to
actually be 128KiB (not 128MiB, as it actually was), and is counted
_after_ resizing, since the point is to limit the amount of data
transfer to clients.

This was discussed in the review of #29999:
https://github.com/zulip/zulip/pull/29999#discussion_r1620818568
The previous way of handling wasn't entirely correct, as unnecessary
events were omitted, with a bad guarantee of even being in the correct
order.
This is an improvement as now the function detects that it ended up
doing nothing and can skip sending an event.
The race condition is hard to make up in an automated test, but we can
hackily simulate it by injecting a side_effect which will create a
conflicting UserPresence row when the function requests a cursor. Aside
of that, the actual race was simulated in manual testing to verify the
expected behavior.
