I found the previous model for computing what settings to use for
streams increasingly difficult to understand, which is generally a
recipe for future bugs.
Refactor to have a clear computation of what complete permissions
state the client is requesting, validate that state, and then pass
that state to the do_change_stream_permission.
We now allow changing access to history of the stream by only passing
"history_public_to_subscribers" parameter. Previously, "is_private"
parameter was also required to change history_public_to_subscribers
otherwise the request was silently ignored.
We also raise error when only history_public_to_subscribers parameter
is passed with value False without "is_private: True" for a public
or web-public stream since we do not allow public streams with
protected history.
We raise error when we try to change a public stream (except for
zephyr mirror realms) to be public with protected history, as we do
not support such streams yet.
Previously, in such case we changed nothing and a notification was
sent to the "stream events" topic with message being "stream is
changed from public to public" and was weird.
Note that this commit only handles the case when both is_private and
history_public_to_subscribers parameters are passed to API and commit
not covers the case when only "history_public_to_subscribers" with
value False is passed to API, since we currently ignore requests
which has only history_public_to_subscribers parameter with not None
and not is_private and is_web_public.
We would do this in further commits when we add support for accepting
only history_public_to_subscribers parameter.
We do not allow changing enable_spectator_access to True using API on
limited plan realms. Frontend changes have been done previously.
This is a follow-up of #22179.
This `mimetype` parameter was introduced in c4fa29a and its last
usage removed in 5bab2a3. This parameter was undocumented in the
OpenAPI endpoint documentation for `/user_uploads`, therefore
there shouldn't be client implementations that rely on it's
presence.
Removes the `request.GET` call for the `mimetype` parameter and
replaces it by getting the `content_type` value from the file,
which is an instance of Django's `UploadedFile` class and stores
that file metadata as a property.
If that returns `None` or an empty string, then we try to guess
the `content_type` from the filename, which is the same as the
previous behaviour when `mimetype` was `None` (which we assume
has been true since it's usage was removed; see above).
If unable to guess the `content_type` from the filename, we now
fallback to "application/octet-stream", instead of an empty string
or `None` value.
Also, removes the specific test written for having `mimetype` as
a url parameter in the request, and replaces it with a test that
covers when we try to guess `content_type` from the filename.
Updates `json_change_settings` so that the default value for the `email`,
`full_name`, `new_password` and `old_password` parameters is `None` instead
of an empty string, which also makes the type annotation `Optional[str]`.
Also, updates tests for email and full name changes to include an empty
string as one of the tested invalid values.
With the new signature of has_request_variables, we can now use
`HttpResponseBase` as the return type of the decorated function.

This makes `has_request_variables` more generic, in the sense of the return
value, and also makes it more accurate, in the sense of requiring the
first parameter of the decorated function to be `HttpRequest`, and
preserving the function signature without using `cast`.
This affects some callers of `has_request_variables` or the callers of its
decoratedfunctions in the following manners:
- Decorated non-view functions called directly in other functions cannot
use `request` as a keyword argument. Becasue `Concatenate` turns the
concatenated parameters (`request: HttpRequest` in this case) into
positional-only parameters. Callers of `get_chart_data` are thus
refactored.
- Functions to be decorated that accept variadic keyword arguments must
define `request: HttpRequest` as positional-only. Mypy in strict mode
rejects such functions otherwise because it is possible for the caller to
pass a keyword argument that has the same name as `request` for `**kwargs`.
No defining `request: HttpRequest` as positional-only breaks type safety
because function with positional-or-keyword parameters cannot be considered
a subtype of a function with the same parameters in which some of them are
positional-only.
Consider `f(x: int, /, **kwargs: object) -> int` and `g(x: int,
**kwargs: object) -> int`. `f(12, x="asd")` is valid but `g(12, x="asd")`
is not.

This makes it mandatory to narrow the type of the user to `UserProfile`

This effectively removes the `request.user` check. We do not call login_page

This commit renames admin_access_required parameter of
list_to_streams function to unsubscribing_others since that
parameter is used and passed as True only when calling
the function while unsubscribing others and in further
commits we would allow non-admins too to unsubscribe others
based on can_remove_subscribers_group setting.
The .status value of EmailChangeStatus was not being looked
at anywhere to prevent re-use of email change confirmation links. This
is not a security issue, since the EmailChangeStatus object has a fixed
value for the new_email, while the confirmation link has expiry time of
1 day, which prevents any reasonable malicious scenarios.
We fix this by making get_object_from_key look at
confirmation.content_object.status - which applies
generally to all confirmations where the attached object has the .status
attribute. This is desired, because we never want to
successfully get_object_from_key an object that has already been used or
reused.
This makes the prereg_user.status check in check_prereg_key redundant so
it can be deleted.
Type inference does not work when the default value of `REQ` is
non-optional while `ResultT` is optional. Mypy tries to unify
`json_validator` with `Validator[int]` in `invite_users_backend` instead
of the desired `Validator[Optional[int]]` because of the presence of the
default value `settings.INVITATION_LINK_VALIDITY_MINUTES`, which is
inferred to be an `int`. Mypy does not resort to a less specific type but
instead gives up early.
This issue applies to invite_users_backend and generate_multiuse_invite_backend
in zerver.views.invite.
There might be a way that we can add an overload to get around this, but
it's probably not worth the complexity until it comes up again more frequently.
We do in fact allow `invite_expires_in_minutes` to be `None` in places
like `do_invite_users`, `invite_users_backend`, etc, and we have
`settings.INVITATION_LINK_VALIDITY_MINUTES` as the default for them. So
it makes sense to allow having an optional value for this setting. And
since there isn't a way to independently set the value of this constant,
we move it to a different place.
TODO:
This is a temporary fix that should be refactored when the bug is fixed.

Fixes#21266.
We want to tie the prereg_user to the MultiUseInvite directly rather
than to the MultiUserInvite's confirmation object, because the latter is
not possible. This is because the flow is that after going through the
multiuse invite link, the PreregistrationUser is created together with a
Confirmation object, creating a confirmation link (via
create_confirmation_link) to which then the user is redirected to finish
account creation. This means that the PreregistrationUser is already
tied to a Confirmation, so that attribute is occupied.
Since we in fact are using the django test client to generate a response
here, the return type should be `TestHttpResponse` instead.

Before this, a link still couldn't be re-used because it would trip up
exception further down user creation codepaths, but that was still a
bug. check_prereg_key is supposed to correctly validate the key - and
trigger an error page being returned if a key (or for any other reason,
the attached PreregistrationUser object) is reused.
test_validate_email_not_already_in_realm needs to be adjusted, because
it was actually re-using a key.
This reverts commit 40fcf5a633.
This commit triggers bug that we haven't fully tracked down, where web
app clients will continually send `update_message_flags` requests,
that then send out via the events system "0 messages were marked as
read" notices, eventually leading to a load spike.
The Tornado part can likely be fixed by checking if
updated_message_ids is empty, but we need to track down the frontend
bug as well.
Instead of using `request.POST` to access `forward_address` for
the parameter used in `set_forward_address` in `email_page`, adds
`has_request_variable` decorator and an optional `forward_address`
parameter through the `REQ` framework.
Adds an assertion that `forward_address` is not `None` for `POST`
requests.
The supertype contains `*args` and `**kwargs`, this adapts the signature
of the `get` method to make MarkdownDirectoryView compatible with it.

The calling arguments here are completely wrong. The first argument
should be `request`, and `self` should never get passed to `.get`.
Because `TemplateView` happened to not use `request`, and we happened
to pass `article` as a keyword argument, this error slipped through.

This change ensures that we can call the validate and update helper for
custom profile data later.
Signed-off-by: Zixuan James Li <p359101898@gmail.com>
We refactor the validator of `update_user_custom_profile_data` to ensure
that the validated variable is properly typed as
a `ProfileDataElementUpdateDict`, so we can call
`validate_user_custom_profile_data` and
`do_update_user_custom_profile_data_if_changed` directly later (unlike
`update_user_backend`, where `value` is allowed to be `None`, the
validator already ensures that no further check is required).
Instead of mutating the original `QueryDict`, we shall create a new
one when updating the `QueryDict`.

This replaces user.is_verified with is_2fa_verified.
The helper does extra checks such that the user being checked for 2fa
authentication status is valid.
`request.user.is_verified` is functionally the same as `is_verified`
from `django_otp.middleware`, except that the former is monkey-patched
onto the user object by the 2FA middleware. We use the latter wrapped
in `is_2fa_verified` instead to avoid accessing the patched attribute.

To explain the rationale of this change, for example, there is
`get_user_activity_summary` which accepts either a `Collection[UserActivity]`,
where `QuerySet[T]` is not strictly `Sequence[T]` because its slicing behavior
is different from the `Protocol`, making `Collection` necessary.
Similarily, we should have `Iterable[T]` instead of `List[T]` so that
`QuerySet[T]` will also be an acceptable subtype, or `Sequence[T]` when we
also expect it to be indexed.
