Setting `ResponseContentDisposition=attachment` means that we override
the stored `ContentDisposition`, which includes a filename. This
means that using the "Download" link on servers with S3 storage
produced a file named the sanitized version we stored.
Explicitly build a `ContentDisposition` to tell S3 to return, which
includes both `attachment` as well as the filename (if we have it
locally).
Apparently, Outlook ignores height/width CSS rules, but does support
the attribute on the image element itself, so specify that instead.
I don't think there are likely to be image tag implementations that
don't support the attribute, given that's the only thing that works in
Outlook.
This test was written back when Django accepted view function names as
strings that might be wrong; that’s not possible in Django ≥ 1.10.

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.
This new property allows organization administrators to specify whether
users can modify the custom profile field value on their own account.
This property is configurable for individual fields.
By default, existing and newly created fields have this property set to
true, that is, they allow users to edit the value of the fields.

The `get_signed_upload_url` code is called for every S3 file serve
request, and is thus in the hot path. The boto3 client caching
optimization is thus potentially useful as a performance optimization.
This commit renames the 'send_event' function to
'send_event_rollback_unsafe' to reflect the fact that it doesn't
wait for the db transaction (within which it gets called, if any)
to commit and sends event irrespective of commit or rollback.
In most of the cases we don't want to send event in the case of
rollbacks, so the caller should be aware that calling the function
directly is rollback unsafe.
If do_delete_messages (and friends) are called for a massive number of
messages, the giant list of message ids is passed to Postgres even
though chunk_size makes all but the first chunk_size of message ids
useless.
This commit renames "allow_deactivated" parameter in
"GET /user_groups" endpoint to "include_deactivated_groups", so
that we can have consistent naming here and for client capability
used for deciding whether to send deactivated groups in register
response and how to handle the related events.
This commit adds code to handle guests separately for group
based settings, where guest will only have permission if
that particular setting can be set to "role:everyone" group
even if the guest user is part of the group which is used
for that setting. This is to make sure that guests do not
get permissions for actions that we generally do not want
guests to have.
Currently the guests do not have permission for most of them
except for "Who can delete any message", where guest could
delete a message if the setting was set to a user defined
group with guest being its member. But this commit still
update the code to use the new function for all the settings
as we want to have a consistent pattern of how to check whether
a user has permission for group-based settings.
We may not always have trivial access to all of the bytes of the
uploaded file -- for instance, if the file was uploaded previously, or
by some other process. Downloading the entire image in order to check
its headers is an inefficient use of time and bandwidth.
Adjust `maybe_thumbnail` and dependencies to potentially take a
`pyvips.Source` which supports streaming data from S3 or disk. This
allows making the ImageAttachment row, if deemed appropriate, based on
only a few KB of data, and not the entire image.
This commit introduced 'creator' and 'date_created'
fields in user groups, allowing users to view who
created the groups and when.
Both fields can be null for groups without creator data.
We only allow updating name of a deactivated group, and not
allow updating description, members, subgroups and any setting
of a deactivated user group.
Deactivated user groups cannot be a a subgroup of any group
or used as a setting for a group.
This is important to make sure that we handle cases when there
are two parallel requests - one for using a group for a setting
and one for deactivating the same group. This makes sure that
atleast one of the above task fails.
This param allows clients to specify how much presence history they want
to fetch. Previously, the server always returned 14 days of history.
With the recent migration of the presence API to the much more efficient
system relying on incremental fetches via the last_update_id param added
in #29999, we can now afford to provide much more history to clients
that request it - as all that historical data will only be fetched once.
There are three endpoints involved:
- `/register` - this is the main useful endpoint for this, used by API
clients to fetch initial data and register an events queue. Clients can
pass the `presence_history_limit_days` param here.
- `/users/me/presence` - this endpoint is currently used by clients to
update their presence status and fetch incremental data, making the new
functionality not particularly useful here. However, we still add the
new `history_limit_days` param here, in case in the future clients
transition to using this also for the initial presence data fetch.
- `/` - used when opening the webapp. Naturally, params aren't passed
here, so the server just assumes a value from
`settings.PRESENCE_HISTORY_LIMIT_DAYS_FOR_WEB_APP` and returns
information about this default value in page_params.
Earlier, the content of the "manage_preferences" block that includes
the unsubscribe_link, personal settings link, etc was missing in the
plaintext version of the custom emails.
This commit updates the logic to include the manage_preferences block
content in the plaintext version.
Renamed event types below in the enum class to use channel instead of
stream.
Event types moved: STREAM_CREATED, STREAM_DEACTIVATED, STREAM_NAME_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.

All endpoints have been migrated to the typed_endpoint decorator,
therefore the has_request_variables decorator and the REQ function are

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.
Fixes the URLRedirects for "help/about-streams-and-topics" and
"help/streams-and-topics" to go to "/help/introduction-to-topics"
since "help/channels-and-topics" has been redirected to that URL.
Ideally this would besplit up into two commits, but it's hard to split
into self-contained, atomic chunks now that this segment of the
import/export system is generally kind of broken after thumbnailing
system changes.
1. 3rd party export converters don't make .original image files.
Insteadthey provide a single file, which the import should treat as if
it's .original.
2. 3rd party converters create all the records with is_animated=False.
That's an issue, because without setting that correctly on the
RealmEmoji objects, Zulip doesn't know that it should use the "still"
thumbnail when the emoji is being used in a user's status. Which leads
to incorrectly displaying the user status with the distracting
animation.
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.
Convert `message_send.py` use `typed endpoint`.
Disable `message_send` endpoint `to` parameter in the `openapi`
`validate_json_schema` check, because it is a special case where the
content type of the parameter is application/json but the
parameter may or may not be JSON encoded since previously we also
accepted a raw string and some ad-hoc bot might still depend on sending
a raw string.
Remove unused validators from `validator.py`.
This commit make changes in code to include can_manage_group
field to UserGroup objects passed with response of various endpoints
including "/register" endpoint and also in the group object
send with user group creation event.
Earlier there was only a realm level setting for configuring
who can edit user groups. A new group level setting is also added
for configuring who can manage that particular group.
Now, a user group can be edited by a user if it is allowed from
realm level setting or group level setting.
This commit make changes to also use group level setting
in determining whether a group can be edited by user or not.
Also, updated tests to use api_post and api_delete helpers instead
of using client_post and client_delete helpers with different users
being logged in.
This commit adds a new group level setting can_manage_group
for configuring who can manage a group. This commit only adds
the field in database and make changes to automatically create
single user groups corresponsing to acting user
which will be the default value for this setting.
Fixes part of #25928.
This commit refactors code in user_groups_in_realm_serialized
such that we do not prefetch "can_mention_group__direct_members"
and "can_mention_group__direct_subgroups" using prefetch_related
and instead fetch members and subgroups for all groups in separate
queries and then use that data to find the members and subgroups
of the group used for that setting.
This change helps us in avoiding two prefetch queries for each
setting when we add more group settings.
Previously, this logic did the database queries to look up UserProfile
objects in a loop.
Fixes#21820.
Significantly improves Stream creation time and also unsusbcribing users.

Add a test case for user unsubscribing themself.
Show user card popover for scheduled messages overlay, compose box
preview, message edit preview, message edit history.
`.messagebox` was chosen as the selector since that was the nearest
parent class that was common for all of the above.
`@all` does not have a popover and that's why it will have the same
pointer as its parent element. We also introduce a new class called
`.user-mention-all` for managing css rules specific to that mention.
The 'tutorial_status' field on 'UserProfile' model is
no longer used to show onboarding tutorial.
This commit removes the 'tutorial_status' field,
'POST users/me/tutorial_status' endpoint, and
'needs_tutorial' parameter in 'page_params'.
Fixes part of zulip#30043.
We plan to remove the 'tutorial_status' field from UserProfile
table as it is no longer used to show tutorial.
The field is also used to narrow a new user in DM with
welcome bot on the first load.
This prep commit updates the logic to use a new OnboardingStep
for the narrowing behaviour on the first load. This will help
in removing the 'tutorial_status' field.
Other than reformatting documentation for Open Collective, this

This commit removes create_web_public_stream_policy setting
since web-public channel creation permissions are now
handled by group-based setting.
We still pass "realm_create_web_public_stream_policy" in
"/register" response though for older clients with its
value being set depending on the value of group based
setting. If we cannot set its value to an appropriate enum
corresponding to the group setting, then we set it to
"Admins and moderators" considering that server will not
allow the users without permissions to create web-public
channels but the client can make sure that UI is
available to the users who have permission.
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).
Earlier, we were immediately enqueueing event in
'do_remove_alert_words' which can lead to a situation, if any
db operation is added after enqueueing event in future, where the

Providing a signed Camo URL for arbitrary URLs opened the server up to
being an open redirector. Return 403 if the URL is not a user upload,
and the backend image if it is. Since we do not have ImageAttachment
rows for uploads at a time we wrote `/thumbnail?` URLs, return the
full-size content.
47683144ff switched the web client to prefer the 840x560 size, as the
mobile apps prefer; remove the now-unused 300x200 size. No client was
using the generated `.jpg` formats, as all clients support `.webp`, so
remove the unused `.jpg` thumbnail as well.
Modern browsers respect the EXIF orientation information of images,
applying rotation and/or mirroring as specified in those tags. The
the `width="..."` and `height="..."` tags are to size the image
_after_ applying those orientation transformations.
The `.width` and `.height` properties of libvips' images are _before_
any transformations are applied. Since we intend to use these to hint
to rendering clients the size that the image should be _rendered at_,
change to storing (and providing to clients) the dimensions of the
rendered image, not the stored bytes.
If the email subject is something like `Fwd:`, it gets stripped to an
empty string, activating the "(no topic)" override. This however leads
to failure if the organization enables the setting forcing every message
to have a topic. Such emails should still go through, so we should just
change the topic value used.
This allows clients to potentially lay out the thumbnails more
intelligently, or to provide a better "progressive-load" experience
when enlarging the thumbnail.
In 'fetch_initial_state_data' we were doing one database query
per announcement stream.
This commit updates the logic to prefetch those streams using
select_related hence avoiding the extra db queries.
Fixes#28909.
The libvips cache is 100MB, 100 operations, or 100 files, whichever is
less. A single Django process or worker is extremely unlikely to ever
see the same image twice, much less within those timeframes.
Disable the cache, since it is mostly useless memory usage for our use
case.
The emoji dir is present in the data from our export tool. This was
added in 468afe4840.
This comment hasn't been updated since

In an interleaved view when composing a message we fade messages
which the user is not replying to, to reduce the chance they send
a message to a recipient they didn't intend to.
Also, it reduces the visual/cognitive processing required
to figure out where their message is going to go.
But, it's not necessarily clear to users that what the
fading means, so this commit adds a one-time compose banner
to explain what's going on the first time this comes up.

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.
This commit improves the assert statements to verify
that the table name is not "usermessage' instead of
verifying that table name doesn't include a substring
"usermessage".
This prep commit will help to avoid assertion error when
importing "onboardingusermessage" table.
Earlier, the export tool was logging a warning:
"??? NO DATA EXPORTED FOR TABLE zerver_onboardingusermessage!!!"
This bug was due to not configuring a Config object for
'OnboardingUserMessage' in 'get_realm_config()'.
This commit fixes the bug to export the table properly.
