The new Stream administrator role is allowed to manage a stream they
administer, including:
* Setting properties like name, description, privacy and post-policy.
* Removing subscribers
* Deactivating the stream
The access_stream_for_delete_or_update is modified and is used only
to get objects from database and further checks for administrative
rights is done by check_stream_access_for_delete_or_update.
We have also added a new exception class StreamAdministratorRequired.
This commit modifies the /streams endpoint so that the web-public
streams are included in the default list of streams that users
have access to.
This is part of PR #14638 that aims to allow guest users to
browse and subscribe themselves to web public streams.
Now we are consistent about validating color/description.
Ideally we wouldn't need to validate the
`streams_raw` parameters multiple times per
request, but the outer function here changes
the error messages to explicitly reference
the "delete" and "add" request variables.
And for the situation where the user-supplied
parameters are correct, the performance penalty
for checking them twice is extremely negligible.
So it's probably fine for now to just make sure
we use the same validators in all the relevant
places.
There's probably some deeper refactor that we
can do to eliminate the whole `compose_views`
scheme. And it's also not entirely clear to
me that we really need to support the update
endpoint. But that's all out of the scope of
this commit.
Currently, we use -1 as the Realm.message_retention_days value to retain
message forever unless specified at stream level for a particular stream,
that is, no policy set at the realm level. But this is incoherent with what
we use for Stream.message_retention_days where -1 means
> disable retention policy for this stream unconditionally
that can be confusing from an API standpoint.
So instead of trying some hack to reset the value to NULL or using some
other value like -2 for RETAIN_MESSAGE_FOREVER and use that for API. It is
much more intuitive to use a string like 'forever' that can be mapped to
RETAIN_MESSAGE_FOREVER at the backend. And this is similar to what we use
for streams settings as well.
Old: a validator returns None on success and returns an error string
on error.
New: a validator returns the validated value on success and raises
ValidationError on error.
This allows mypy to catch mismatches between the annotated type of a
REQ parameter and the type that the validator actually validates.

Rename the validator to check_union, to conform
more to Python typing nomenclature.
And we rename one of the test helpers to the
simpler `check_types`. (The test helper
was using "variable" in the "var" sense.)
This commit adds backend support for setting message_retention_days
while creating streams and updating it for an existing stream. We only
allow organization owners to set/update it for a stream.
'message_retention_days' field for a stream existed previously also, but
there was no way to set it while creating streams or update it for an
exisiting streams using any endpoint.
Fixes#2665.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split

This commit extracts removing_someone_else logic to the function

This is a follow up to 2187c84.
This commit modifies the backend to accept user ids when subscribing
users to streams.
It also migrates all existing tests to use this API, aside from a
small set of tests for the legacy API.
Since production testing of `message_retention_days` is finished, we can
enable this feature in the organization settings page. We already had this
setting in frontend but it was bit rotten and not rendered in templates.
Here we replaced our past text-input based setting with a
dropdown-with-text-input setting approach which is more consistent with our
existing UI.
Along with frontend changes, we also incorporated a backend change to
handle making retention period forever. This change introduces a new
convertor `to_positive_or_allowed_int` which only allows positive integers
and an allowed value for settings like `message_retention_days` which can
be a positive integer or has the value `Realm.RETAIN_MESSAGE_FOREVER` when
we change the setting to retain message forever.
This change made `to_not_negative_int_or_none` redundant so removed it as
well.
Fixes: #14854

This is a prep commit for making use of same choices for
create_stream_policy and invite_to_stream_policy as both fields
have same set of choices.
This will be useful as we add other fields using these same types.
This commit replaces the WAITING _PERIOD with FULL_MEMBERS from
create_stream_policy and invite_to_stream_policy choices to
achieve consistency and making the variables more descriptive.
This is a full-stack change:
- server
- JS code
- templates
It's all pretty simple--just use stream_id instead
of stream_name.
I am 99% sure we don't document this API nor use it
in mobile, so it should be a safe change.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.
It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.
This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.
With many tweaks by tabbott to documentation under /help, etc.
Fixes#13616.
Adds required API and front-end changes to modify and read the
wildcard_mentions_notify field in the Subscription model.
It includes front-end code to add the setting to the user's "manage
streams" page. This setting will be greyed out when a stream is muted.
The PR also includes back-end code to add the setting the initial state of
a subscription.
New automated tests were added for the API, events system and front-end.
In manual testing, we checked that modifying the setting in the front end
persisted the change in the Subscription model. We noticed the notifications
were not behaving exactly as expected in manual testing; see
https://github.com/zulip/zulip/issues/13073#issuecomment-560263081 .

The function only used the user's realm anyway, so this is a cleaner
API.
This should also make it more convenient to permanently delete
messages manually, since one doesn't have to fetch a random user in
the realm in order to delete a message using the management shell.
No functional change.
Previously, our OpenAPI documentation validation was failing for some
endpoints because it didn't account for the `in: path` type of
parameter, resulting in a mismatch between what was declared via REQ
and what was declared in the OpenAPI docs.
We fix this by excluding the path type parameters in both places from
what's considered by documentation using the `path_only` flag.
I doubt this is the correct long-term fix; in particular, I don't
think we're actually running the validators for these path-only
parameters. The examples that exist today are all IDs with validators
for being non-negative numbers, but longer-term I think we'll want to
do something different (possibly at the REQ layer, see the TODO).
The `users/me/subscriptions` endpoint accidentally started returning
subscriber information for each stream. This is convenient, but
unnecessarily costly for those clients which either don't need it
(most API apps) or already acquire this information via /register
(including Zulip's apps).
This change removes that data set from the default response. Clients
which had come to rely on it, or would like to rely on it in future,
may still access it via an additional documented API parameter.
Fixes#12917.
When a person creates a new realm, they'll likely want to create a
bunch of initial streams at once. When doing so, it could be annoying
to have to mark all of the new stream notification messages as read.
Thus to make this process smoother, we should automatically mark
the messages generated by the Notification Bot in the notifications
(announcements) stream, as well as in the newly created stream itself
as read by the stream creator.
Fixes#12765.
We implicitly assume settings.NOTIFICATION_BOT is not None just a few lines
above, in
sender = get_system_bot(settings.NOTIFICATION_BOT)
notifications.append(
internal_prep_private_message(
realm=user_profile.realm,
sender=sender,
...
This will make it easier to have access to the stream creator.
The indirection also isn't really adding anything, especially given that the
announce message is inlined just above.
This renames Subscription.in_home_view field to is_muted, for greater
clarity as to what it does just from seeing the setting name, without
having to look it up.
Also disabled an obsolete test_migrations test.
Fixes#10042.
This commit creates a new organization setting that determines whether
a user can invite other users to streams. Previously this was linked
to the waiting period threshold, but this was both not documented and
overly limiting.
With significant tweaks by tabbott to change the database model to not
involve two threshhold fields, edit the tests, etc.
This requires follow-up work to make the create stream policy setting
work how this code implies it should.
Fixes#12042.
This is important for situations such as with our Zapier app,
where the requesting user may be a bot that would like to access
its owner's subscriptions.
Tweaked by tabbott to eliminate the 2^N growth of cases in
do_get_streams.
We do not anticipate our UI for showing stream descriptions looking
reasonable for multi-line descriptions, so we should just ban creating
them.
Given the frontend changes, multi-line descriptions are only likely to
show up from importing content from other tools, in which case
replacing newlines with spaces is cleaner than the alternative.
For internal stream messages, most of the time, we have access to
a Stream object. For the few corner cases where we don't, it is a
much cleaner approach to have a separate function that accepts a
stream name than having one multi-option helper that accepts both
names and objects.
If the caller has access to a Stream object, it is wasteful to
query a database for a stream by ID or name. In addition, not
having to go through stream names eliminates various classes of
possible bugs involved with getting a Stream object back.
This is primarily a feature for onboarding, where an organization
administrator might send a bunch of random test messages as part of
joining, but then want a pristine organization when their users later
join.
But it can theoretically be used for other use cases (e.g. for
moderation or removing threads that are problematic in some way).
Tweaked by tabbott to handle corner cases with
is_history_public_to_subscribers.
Fixes#10912.
This doesn't have any security impact, since we overwrote any other
fields in any case, and also this step happens before the security
part of input validation for stream creation. But this does improve
error messages if one tries to specify other arguments, and also makes
more clear that the `description` argument is supported here.
This fixes an annoying bug where clicking to subscribe to a stream
would change the color shown in the "manage streams" UI immediately
after you click.
Fixes#11072.
Previously, the subscription color attribute had a validator of
check_string, but this is insufficient. Hence this commit update the
validator used to check_color. Fixes#11268.
Feature of sending notification to the stream using notification bot
is added. user_profile is also passed to do_rename_stream for using
the name of user who renamed the stream in notification.
Notification is sent to the stream using
internal_send_stream_message in do_rename_stream.
Fixes#11034.
We start by including functions that do custom
queries for topic history.
The goal of this library is partly to quarantine
the legacy "subject" column on Message.
This fixes a bug where administrators couldn't remove private
unsubscribed streams from the "default streams" list, because
access_stream_by_name didn't give them access to the stream object.
This is all the plumbing that makes it possible to enable the
stream_email_notifications setting via the Zulip API. The flag still
doesn't do anything yet, but this is a nice checkpoint along the way
to implementing this feature.
We're adding more stream types, e.g. splitting private streams into
with/without shared history, adding publicly-archived streams, adding
announce-only streams, etc. So maintaining this text is going to get more
complicated over time.
Also, the right place to explain this stuff is in the stream header, or near
the z-in-a-circle.
This commit also adds translation tags to the messages.
This query was incorreclty not checking whether a user was deactivated
before managing their subscriptions.
This isn't an important bug, but should prevent some weird corner
cases (like trying to send a notification PM to a deactivated user,
which fails).
These decorators will be part of the process for disabling access to
various features for guest users.
Adding this decorator to the subscribe endpoint breaks the guest users
test we'd just added for the subscribe code path; we address this by
adding a more base-level test on filter_stream_authorization.
This removes a check on invite_only, that should have been a check on
history_public_to_subscribers. In addition to fixing a bug for zephyr
realms, it also makes "more topics" work correctly for realms using
the new settings for stream history being public to subscribers.
This commit adds a new field history_public_to_subscribers to the
Stream model, which serves a similar function to the old
settings.PRIVATE_STREAM_HISTORY_FOR_SUBSCRIBERS; we still use that
setting as the default value for new streams to avoid breaking
backwards-compatibility for those users before we are ready with an
actual UI for users to choose directly.
This also comes with a migration to set the value of the new field for
existing streams with an algorithm matching that used at runtime.
With significant changes by Tim Abbott.
This is an initial part of our efforts on #9232.
This will allow realm admins to remove others from private stream to
which the realm administrator is not subscribed; this is important for
managing those streams, because previously nobody could remove users
from private streams that didn't have any realm administrators
subscribed.
This will allow realm admins to access subscribers of unsubscribed
private stream. This is a preparatory commit for letting realm admins
remove those users.
This will allow realm admins to update the names and descriptions of
private streams even if they are not subscribed, which fixes the buggy
behavior that previously nobody could(!).
Apparently, we did essentially all the work to support showing full
topic history to newly subscribed users from a data flow perspective,
but didn't actually enable this feature by having the topic history
endpoint grant access to historical topics. This fixes that gap.
I'm not altogether happy with how the code and tests read for this
feature; the code itself has more duplication than I'd like, and the
tests do too, but it works.
There might be case that NOTIFICATION_BOT is none, so before sending stream
announce notification, check first if settings.NOTIFICATION_BOT is not none.
