This commit adds 'durable=True' to the outermost transaction
in 'delete_message_backend'.
It also adds 'savepoint=False' to inner transaction.atomic
decorator to avoid creating savepoint.
This is as a part of our plan to explicitly mark all the
transaction.atomic decorators with either 'savepoint=False' or
'durable=True' as required.
* 'savepoint=True' is used in special cases.
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.
f92d43c690 added uses of `@overload` to probide multiple type
signatures for `access_message`, based on the `get_user_message`
parameter. Unfortunately, mypy does not check the function body
against overload signatures, so it allows type errors to go
undetected.
Replace the overloads with two functions, for one of which also
returns the usermessage. The third form, of only returning if the
usermessage exists, is not in a high-enough performance endpoint that
a third form is worth maintaining; it uses the usermessage form.
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 adds code to not include original details of senders like
name, email and avatar url in the message objects sent through events
and in the response of endpoint used to fetch messages.
This is the last major commit for the project to add support for
limiting guest access to an entire organization.
Fixes#10970.
This commit adds support to allow bot-owners to delete messages
sent by their bots if they are allowed to delete their own messages
as per "delete_own_message_policy" setting and the message delete
time limit has not passed.
Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)

Previously we did not send notification for topic-only edits.
Now, we add backend support for sending notification to topic-only
edits as well.
We would add support for this in webapp in further commits since
message edit UI will be updated as well. We just make sure that no
notifications are sent when editing topic using pencil icon in
message header.
We also change the API default for moving a topic to only notify the
new location, not the old one; this matches the current defaults in
the web UI.
Includes many tests.
We also update the puppeteer tests to test only content edit as
we are going to change the UI to not allow topic editing from
message edit UI. Also fixing the existing tests to pass while
doing topic edits is somewhat complex as notification message
is also sent to new topic by default.
Fixes#21712.

This is preparatory commit for #18941.
Importing `do_delete_message` from `message_edit.py` was causing a
circular import error. In order to avoid that, we create a separate
message_delete.py file which has all the functions related to deleting
messages.
The tests for deleting messages are present in
`zerver/tests/test_message_edit.py`.
Fixes a part of #18941
We were not setting the `historical` flag correctly for
messages fetched via `json_fetch_raw_message` when used didn't
have any UserMessage.
Extended relevant tests to fetch check message flags too.
Previously, this URL just returned the `raw_content` field. It seems
cleanest to just make it a single-message variant of GET /messages,
deprecating the only format.
Since we've changed the database to contain these new fields, we just
need to stop dropping them in the API code.
This also changes the public API to match the database format again
by removing `prev_subject` from edit history API.
Adds an API changelog feature update for the renamed `prev_subject`
field (to `prev_topic`) and new fields (`topic` and `stream`)
in the message `edit_history`.
Also, documents said `edit_history` in the `MessagesBase` schema
in the api documentation, which is used by the `/get-messages`,
`/get-events` and `/zulip-outgoing-webhooks` endpoints.
Fixes#21076.

We fix the mutation of caller and other bad patterns, as well as
adding explicit typing to make the code readable.
We also update the OpenAPI documentation for previously
undocumented `prev_strem` field in the `/get-message-history`
endpoint for API validation testing.

Adds request as a parameter to json_success as a refactor towards
making `ignored_parameters_unsupported` functionality available
for all API endpoints.
Also, removes any data parameters that are an empty dict or
a dict with the generic success response values.
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 utilizes the generic `BaseNotes` we added for multipurpose
patching. With this migration as an example, we can further support
more types of notes to replace the monkey-patching approach we have used
throughout the codebase for type safety.
JsonableError has two major benefits over json_error:
* It can be raised from anywhere in the codebase, rather than
being a return value, which is much more convenient for refactoring,
as one doesn't potentially need to change error handling style when
extracting a bit of view code to a function.
* It is guaranteed to contain the `code` property, which is helpful
for API consistency.
Various stragglers are not updated because JsonableError requires
subclassing in order to specify custom data or HTTP status codes.
Further commits will start locking the message rows while
adding related fields like reactions or submessages,
to handle races caused by deleting the message itself at the
same time.
The message locking implemented then will create a possibility
of deadlocks, where the related field transaction holds a lock
on the message row, and the message-delete transaction holds a
lock on the database row of the related field (which will also
need to be deleted when the message is deleted), and both
transactions wait for each other.
To prevent such a deadlock, we lock the message itself while
it is being deleted, so that the message-delete transaction
will have to wait till the other transaction (which is about
to delete the related field, and also holds a lock on the
message row) commits.

As of now, editing a widget doesn't update the rendered content.
It's important to ensure that existing votes or options added later on
don't get deleted when rendered.
This seems more complex than it's worth.
For now, we just prevent edits to widgets.
This commit makes the UI clearer that editing widgets isn't allowed.

This wasn't being validated before. There wasn't any possibility to
actually succeed in moving a private message, because the codepath would
fail at assert message.is_stream_message() in do_update_message - but we
should have proper error handling for that case instead of internal
server errors.
Otherwise an admin can move a topic from a private stream they're no
longer a part of - including the newest messages in the topic, that
they're not supposed to have access to.
A bug in the implementation of the topic moving API resulted in
organization administrators being able to move messages to streams they
shouldn't be allowed to - private streams they weren't subscribed to and
streams in other organization hosted by the same Zulip installation.
In our current model realm admins can't send messages to private streams
they're not subscribed to - and being able move messages to a
stream effectively allows to send messages to that stream and thus the
two need to be consistent.
This makes it much more clear that this feature does JSON encoding,
which previously was only indicated in the documentation.

We always want to do these at the same time. Previously, message

Fixes#16284.
Most of the work for this was done when we implemented correct
behavior for guest users, since they treat public streams like private
streams anyway.
The general method involves moving the messages to the new stream with
special care of UserMessage.
We delete UserMessages for subs who are losing access to the message.
For private streams with protected history, we also create UserMessage
elements for users who are not present in the old stream, since that's
important for those users to access the moved messages.
