We send user_id of the referrer instead of email in the invites dict.
Sending user_ids is more robust, as those are an immutable reference
to a user, rather than something that can change with time.
Updates to the webapp UI to display the inviters for more convenient
inspection will come in a future commit.
In zulip.yaml, add `deprecated` tags to all parameters/keys with
`Deprecated` in the description. Then add tests to ensure that deprecated
parameters/keys will always have the `deprecated` key. Also, in
the API docs, sort the parameters according to presence of `deprecated`
key, presenting the `deprecated` keys at the end and add a `deprecated`
tag next to them.
Change variable `name` to `date_sent` as `name` actually stores
the date sent. Also change the data types of `name` and `create_time`
to integer. As they actually have empty decimal value.
Due to authentication restrictions, a deployment may need to direct
traffic for mobile applications to an alternate uri to take advantage
alternate authentication mechansism. By default the standard realm URI
will be usedm but if overridden in the settings file, an alternate uri
can be substituted.
We send a remove mobile push notification to the users who were
no longer mentioned after the content of the message was edited.
This also corrects the notification count for the mobile apps
where a user was prior mentioned in a muted stream / topic and the
message was edited and the user is no longer mentioned now.
Hence, fixing the case where user has read all his unreads
but the notification badge on the app is still positive.
Fixes#15428.
do_clear_mobile_push_notifications_for_ids can now be used to
clear push_notification for multiple users at once. This method
loops over users, so no performance optimization is gained.
We've been seeing an exception in server_event_dispatch.js in
production where in large organizations, sometimes when a new user
joined, every other browser in the organization would throw an
exception processing some sort of realm_user/update event.
It turns out the cause was that when a user copies their profile from
an existing user account with a user-uploaded avatar, the code path we
reused to set the avatar properly send a realm_user/update event about
the avatar change -- for a user that hadn't been fully created and
certainly hadn't have the realm_user/add event sent for.
We fix this and add tests and comments to prevent it recurring.
(Removed an incorrect docstring while working on this).
The restart event was always handled pretty similarly
to pointer, so I use restart events now for this
test (in preparation of eliminating pointer events).
This eval function performs the inverse of the implicit
stringification that’s implied by this type-incorrect assignment in
do_update_user_custom_profile_data_if_changed:
field_value.value = field['value']
We believe there’s sufficient validation for the data being passed to
this eval that it could only have been exploited by a PostgreSQL
administrator editing the database manually.

This fixes an issues that causes HTML entities inside of inline code
blocks to be converted rather than being displayed literally.
The upstream python-markdown now handles this correctly, so we just use
their implementation with our changes for removing .strip(). As a result
of this migration, we switch backtick pattern to an inline processor
too.
Fixes#12056.

* Reordered the settings relevant without stream creation to the top.
* Removed useless/misleading defaults for optional parameters.
* Clarified description of the announce and authorization_errors_fatal settings.
* Clarified that `invite_only` only applies for stream creation.
(It's annoying to do so for its friends because they are including
common description content and OpenAPI doesn't have a way to have
extra content in a place you included something)
Fixes#14705.
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.
Note that I don't actually convert the
checker from check_dict to check_dict_only,
because that would be a user-facing change,
but I think we can sweep a lot of things
like this after the next release.
This avoids some code duplication as well
as adding some missing fields.
We also use check_dict_only to prevent
folks from adding new fields to the
relevant events without updating these
tests. (A bigger sweep comes later.)
As the code comment indicates, we just
use a strict check here rather than
pretending that the test exercises a
more complicated schema for the config
data, which is dynamic in nature.
Cleaning up config_data is outside the
scope of this PR; my main goal is to
eliminate check_dict calls (usually in favor
of check_dict_only).
Because of other validation on these values, I don't believe any of
these does anything different, but these changes improve readability
and likely make GitHub's code scanners happy.
The helper should be used instead of constructing the dict manually.
Change get_account_data_dict, on GitHubAuthBackendTest
class, so it has a third argument, user_avatar_url.
This is a preparation for support using GitHub avatar
upon user resgistration (when the user logs using
GitHub).
Update the REQ check for profile_data in
update_user_backend by tweaking `check_profile_data`
to use `check_dict_only`.
Here is the relevant URL:
path('users/<int:user_id>', rest_dispatch,
{'GET': 'zerver.views.users.get_members_backend',
It would be nice to unify the validator
for these two views, but they are different:
update_user_backend
update_user_custom_profile_data
It's not completely clear to me why update_user_backend
seems to support a superset of the functionality
of `update_user_custom_profile_data`, but it has
this code to allow you to remove custom profile fields:
clean_profile_data = []
for entry in profile_data:
assert isinstance(entry["id"], int)
if entry["value"] is None or not entry["value"]:
field_id = entry["id"]
check_remove_custom_profile_field_value(target, field_id)
else:
clean_profile_data.append({
"id": entry["id"],
"value": entry["value"],
})
Whereas the other view is much simpler:
def update_user_custom_profile_data(
<snip>
) -> HttpResponse:
validate_user_custom_profile_data(user_profile.realm.id, data)
do_update_user_custom_profile_data_if_changed(user_profile, data)
# We need to call this explicitly otherwise constraints are not check
return json_success()
This tightens our checking of user-supplied data
for this endpoint:
path('users/me/profile_data', rest_dispatch,
{'PATCH': 'zerver.views.custom_profile_fields.update_user_custom_profile_data',
...
We now explicitly require the `value` field
to be present in the dicts being passed in
here, as part of `REQ`. There is no reason
that our current clients would be sending
extra fields here, and we would just ignore
them anyway, so we also move to using
check_dict_only.
Here is some relevant webapp code (see settings_account.js):
fields.push({id: field.id, value: user_ids});
update_user_custom_profile_fields(fields, channel.patch);
settings_ui.do_settings_change(method, "/json/users/me/profile_data",
{data: JSON.stringify([field])}, spinner_element);
The webapp code sends fields one at a time
as one-element arrays, which is strange, but
that is out of the scope of this change.
After some discussion, everyone seems to agree that 3.0 is the more
appropriate version number for our next major release. This updates
our documentation to reflect that we'll be using 3.0 as our next major
release.
`/api/v1/fetch_api_key`'s response had a key `email` with the user's
delivery email. But its JSON counterpart `/json/fetch_api_key`, which
has a completely different implementation, did not return `email` in
its success response.
So to avoid confusion, the non-API endpoint, `/json/fetch_api_key`
response has been made identical with it's `/api` counterpart by
adding the `email` key. Also it is safe to send as the calling user
will only see their own email.
We now have our muted topics use tuples internally,
which allows us to tighten up the annotation
for get_topic_mutes, as well as our schema
checking.
We want to deprecate sub_validator=None
for check_list, so we also introduce
check_tuple here. Now we also want to deprecate
check_tuple, but it's at least isolated now.
We will use this for data structures that are tuples,
but which are sent as lists over the wire. Fortunately,
we don't have too many of those.
The plan is to convert tuples to dictionaries,
but backward compatibility may be tricky in some
places.
This commit changes do_get_user_invites function to not return
multiuse invites to non-admin users. We should only return multiuse
invites to admins, as we only allow admins to create them.
This commit changes the PreregistrationUser.invite_as dict to have
same set of values as we have for UserProfile.role.
This also adds a data migration to update the already exisiting
PreregistrationUser and MultiuseInvite objects.
Streams can have lots of subscribers, meaning that the archiving process
will be moving tons of UserMessages per message. For that reason, using
a smaller batch size for stream messages is justified.
Some personal messages need to be added in test_scrub_realm to have
coverage of do_delete_messages_by_sender after these changes.
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.
To be more consistent with the meaning in the Stream model, and to make
it easier to have a reasonable settings API, we get rid of the None
value for Realm.message_retention_days in favor of the value -1 to
represent the "don't delete messages" default policy.
In 5200598a31, we introduced a new
client capability that can be used to avoid unreasonable network
bandwidth consumed sending avatar URLs of long term idle users in
organizations with 10,000s members.
This commit enables this feature and adds support for it to the web
client.
subdomain=None didn't make much sense as a value, and wasn't actually in
use anywhere, except one test where it was accidental. All tests specify
the subdomain explicitly, so we should change the type to str, and make
it an obligatory kwarg.
Adds the ability to set a SAML attribute which contains a
list of subdomains the user is allowed to access. This allows a Zulip
server with multiple organizations to filter using SAML attributes
which organization each user can access.
Cleaned up and adapted by Mateusz Mandera to fit our conventions and
needs more.

Also, `send_message` example is altered to send a message to the
stream 'social' to avoid getting a "first_message_id: null"
in the response for `get_subscriptions` example, that caused
`validate_against_openapi_schema` to throw an error.
The `EXCLUDE_PROPERTIES` is a dictionary in `zerver/openapi/openapi.py`
which holds the undocumented properties of our API. Document all
properties other than:
*`delivery_email` which is in another PR.
*'events' and 'register'.
*'/setting/notification' since its response is about to undergo heavy
changes.
A generator that yields values without receiving or returning them is
an Iterator. Although every Iterator happens to be iterable, Iterable
is a confusing annotation for generators because a generator is only
iterable once.

In a decorator annotated with generic type (ViewFuncT) -> ViewFuncT,
the type variable ViewFuncT = TypeVar(…) must be instantiated to
the *same* type in both places. This amounts to a claim that the
decorator preserves the signature of the view function, which is not
the case for decorators that add a user_profile parameter.
The corrected annotations enforce no particular relationship between
the input and output signatures, which is not the ideal type we might
get if mypy supported variadic generics, but is better than enforcing
a relationship that is guaranteed to be wrong.
This removes a bunch of ‘# type: ignore[call-arg] # mypy doesn't seem
to apply the decorator’ annotations. Mypy does apply the decorator,
but the decorator’s incorrect annotation as signature-preserving made
it appear as if it didn’t.

We had a bug in `validate_against_openapi_schema` that prevented it
from correctly inspecting nested arrays.
Fix the bug and address all the exceptions, either via
EXCLUDE_PROPERTIES or fixing them when simple. Also add a test case
for nested verification.
Attachment objects in production are only created in one place, which
passses a size. Additionally, I verified in multiple production
environments with old data that this never actually happens (or has
happened).
So we should make the data model correctly reflect the possibilities here.
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.)
We assert that the post was successful, to give
more immediate feedback for tests that don't
bother to check the return value and may be
implicitly assuming this method just works in
all cases.
And we also make it more convenient for tests
that are happy-path tests--they don't have to
do the assertion themselves. (And they're still
free to do deeper checks on the json.)
We opt out with allow_fail=True. We probably want
a more direct API eventually for tests that are
clearly trying to test the failure path for
subscribing to streams.
It's possible that a couple tests here that I added
allow_fail=True to just have flawed data setup--
I don't have time to investigate all cases, but
hopefully they will at least stand out more.
The non-search code path here was simulating the response and escaping
logic from get_search_fields by duplicating what it would do with an
empty set of highlight locations.
We can produce much more readable code by just passing an empty list
of locations in this case.
Two things were broken here:
* we were using name(s) instead of id(s)
* we were always sending lists that only
had one element
Now we just send "stream_id" instead of "subscriptions".
If anything, we should start sending a list of users
instead of a list of streams. For example, see
the code below:
if peer_user_ids:
for new_user_id in new_user_ids:
event = dict(type="subscription", op="peer_add",
stream_id=stream.id,
user_id=new_user_id)
send_event(realm, event, peer_user_ids)
Note that this only affects the webapp, as mobile/ZT
don't use this.
Currently the API docs do not specify whether a given API parameter
is to be specified in `query` or in `path`. Edit the docs so as
to show the type of argument right beside argument name.
Currently, the OpenAPI extension for rendering description in docs
cannot parse {!api-admin-only.md!}. Edit order of markdown extensions
in app_filters.py so that rendering of OpenAPI elements takes place
before substitution of files using `include`.
The loop I added here in 5b49839b08 was
ill-conceived. The critical issue was that despite its name,
do_clear_mobile_push_notifications_for_ids does not immediately clear
push notifications (Except in our test suite, where `send_event`
immediately calls into the queue worker code!).
Instead, it queues work to clear those push notifications. Which
means that the first user to declare bankruptcy with a large number of
unreads will fill the queue, and then this will just be an infinite
loop adding more work to the queue.
This fixes a missing unique constraint on the Reactions data model
state when using multiple aliases for an emoji code. As with any
missing unique constraints, we first need to apply a migration that
eliminates violations of the rule; in this case, deleting the
duplicates is correct.
Added unique constraint for "user_profile", "message",
"reaction_type", "emoji_code".
Fixes#15347.
Mostly, this is a change in ordering to make more sense, but we also
fix several names that were clearly confusing.
We restore the convention that each endpoint has the same title at the
top of the page as what we have in the sidebar menu, which appears to
have been violated in many recent updates to API documentation.
api docs filenames are basically the operationId of their endpoint
in zulip.yaml with `_` replaced by `-`. But some operationIds have
changed, so change the affected filenames. Make changes in other
files accordingly.
This adds a new client_capability that clients such as the mobile apps
can use to avoid unreasonable network bandwidth consumed sending
avatar URLs in organizations with 10,000s of users.
Clients don't strictly need this data, as they can always use the
/avatar/{user_id} endpoint to fetch the avatar if desired.
This will be more efficient especially for realms with
10,000+ users because the avatar URLs would increase the
payload size significantly and cost us more bandwidth.
Fixes#15287.
We need this field to avoid O(N) database operations
while fetching realm user data for clients with
`user_avatar_url_field_optional` flag enabled.
Part of #15287.
This extends get_accounts_for_email test by adding a deactivated
user and assert that get_accounts_for_email doesn't return any accounts
for that deactivated user.
Fixes#14807.
With #14378, we regressed back to the state of that
prior to 7e0ea61b00.
We fix this by getting our avatar bucket on
object initialization, and use the appropriate means
of gathering the network location for the urls.
Fixes#14484.
_setup_export_files modifies the zulip realm. We used to
call realm.refresh_from_db in tests after _setup_export_files was
called to make sure that the change is reflected. But sometimes
calling refresh_from_db was missed out here and there.
This commit makes calling refresh_from_db after _setup_export_files
unnecessary.
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.
Previously, we had implemented:
<span class="timestamp" data-timestamp="unix time">Original text</span>
The new syntax is:
<time timestamp="ISO 8601 string">Original text</time>
<span class="timestamp-error">Invalid time format: Original text</span>
Since python and JS interpretations of the ISO format are very
slightly different, we force both of them to drop milliseconds
and use 'Z' instead of '+00:00' to represent that the string is
in UTC. The resultant strings look like: 2011-04-11T10:20:30Z.
Fixes#15431.
The term `parameter` is a better word than `argument` for data passed
to an API endpoint; this is why OpenAPI uses in their terminology.
Replace `argument` with `parameter` in the API docs to improve their
readability.
Fixes#15435.
Fixes#14498.
When a topic is moved to a different stream, the message may no
longer be reachable to guest user, if the user is not subscribed
to the new stream.
We used to send message update event to the client in these cases,
which seems to be confusing both to the client updating the message
and the server sending push_notifications for it.
Now, we delete the UserMessage entry for these messages for the
user and send a delete message event to the client; which makes
both push_notification and the event handling client think that
the message was deleted and hence no confusion in the code is
raised.
This makes the system store and track PushDeviceToken objects on
the local Zulip server when using the push notifications bouncer
and includes tests for this.
This is something we need to implement end-to-end encryption for
push notifications. We'll add the encryption key as an additional
property on the local PushDeviceToken object.
It also likely adds some value in the case that a server were to
switch between using the bouncer service and sending notifications
directly, though in practice that's unlikely to happen.
This migration fixes any PreregistrationUser objects that might have
been already corrupted to have the administrator role by the buggy
original version of migration 0198_preregistrationuser_invited_as.
Since invitations that create new users as administrators are rare, it
is cleaner to just remove the role from all PreregistrationUser
objects than to filter for just those older invitation objects that
could have been corrupted by the original migration.
This migration incorrectly swapped the role associated with invitation
objects between members and organization administrators, resulting in
most invitation objects that existed before the upgrade to Zulip
2.0.0-rc1 or later to be incorrectly administrator invitations.
Fixing the migration is safe and will help those installations
upgrading directly from 1.9.x to 2.1.5 or later.
A migration to fix the corrupted records will appear in an upcoming
commit.
The most import change here is the one in maybe_send_to_registration
codepath, as the insufficient validation there could lead to fetching
an expired PreregistrationUser that was invited as an administrator
admin even years ago, leading to this registration ending up in the
new user being a realm administrator.
Combined with the buggy migration in
0198_preregistrationuser_invited_as.py, this led to users incorrectly
joining as organizations administrators by accident. But even without
that bug, this issue could have allowed a user who was invited as an
administrator but then had that invitation expire and then joined via
social authentication incorrectly join as an organization administrator.
The second change is in ConfirmationEmailWorker, where this wasn't a
security problem, but if the server was stopped for long enough, with
some invites to send out email for in the queue, then after starting it
up again, the queue worker would send out emails for invites that
had already expired.
Google has removed the Google Hangouts brand, thus we are removing
them as video chat provider option.
This commit removes Google Hangouts integration and make a migration

Fixes: #15298.
Fixes#14828.
Giving the /subdomain/<token>/ url there could feel buggy if the user
ended up using the token in the desktop app, and then tried clicking the
"continue in browser" link - which had the same token that would now be
expired. It's sufficient to simply link to /login/ instead.
This adds support for a "spoiler" syntax in Zulip's markdown, which
can be used to hide content that one doesn't want to be immediately
visible without a click.
We use our own spoiler block syntax inspired by Zulip's existing quote
and math block markdown extensions, rather than requiring a token on
every line, as is present in some other markdown spoiler
implementations.
Fixes#5802.

This adds a new function `get_apns_badge_count()` to
fetch count value for a user push notification and
then sends that value with the APNs payload.
Once a message is read from the web app, the count is
decremented accordingly and a push notification with
`event: remove` is sent to the iOS clients.
Fixes#10271.
Mocking `get_base_payload()` verifies the wrong output
when the code is actually correct. So, its better that
we call the real function here, especially when we are
adding the Apple case.
This line was effectively hardcoding a specific stream_post_policy,
overriding the value already present in the event, to no purpose.
(I believe it got here via cargo-culting induced by #13787.)
This commit removes is_old_stream property from the stream objects
returned by the API. This property was unnecessary and is essentially
equivalent to 'stream_weekly_traffic != null'.
We compute sub.is_old_stream in stream_data.update_calculated_fields
in frontend code and it is used to check whether we have a non-null
stream_weekly_traffic or not.
Fixes#15181.
This likely fix a bug that can leak thousands of messages into the
invalid state where:
* user_message.flags.active_mobile_push_notification is True
* user_message.flags.read is True
which is intended to be impossible except during the transient process
between marking messages as read sending the "remove push
notifications" event.
The bug is that if a user who is declaring bankruptcy with 10,000s of
unreads ends up having the database query to mark all of those as read
take 60s, the Django/uwsgi request will time out and kill the process.
If the postgres transaction still completes, we'll end up with the
second half of this function never being run.
A safer ordering is to do the smaller queries first.
We do this in a loop for correctness in the unlikely event there are
more than 10,000 of these.
Fixes#15285
This event will be used more now for guest users when moving
topic between streams (See #15277). So, instead of deleting
messages in the topic as part of different events which is
very slow and a bad UX, we now handle the messages to delete in
bulk which is a much better UX.

This is designed to have no user-facing change unless the client
declares bulk_message_deletion in its client_capabilities.
Clients that do so will receive a single bulk event for bulk deletions
of messages within a single conversation (topic or PM thread).
Backend implementation of #15285.
This commits adds restriction on admins to set message retention policy.
We now only allow only organization owners to set message retention
policy.
Dropdown for changing retention policy is disabled in UI for admins also.
Whenever we use API queries to mark messages as read we now increment
two new LoggingCount stats, messages_read::hour and
messages_read_interactions::hour.
We add an early return in do_increment_logging_stat function if there
are no changes (increment is 0), as an optimization to avoid
unnecessary database queries.
We also log messages_read_interactions::hour Logging stat
as the number of API queries to mark messages as read.
We don't include tests for the case where do_update_pointer is called
because do_update_pointer will most likely be removed from the
codebase in the near future.
This uses `where_active_push_notification()` instead of
the flag condition to keep it consistent with the app
code as we use the same function to filter active push
notifications everywhere else.
Overrides some of internal functions of python-social-auth
to handle native flow.

This adds a powerful end-to-end test for Zulip's API documentation:
For every documented API endpoint (with a few declared exceptions that
we hope to remove), we verify that every API response received by our
extensive backend test suite matches the declared schema.
This is a critical step towards being able to have complete, high
quality API documentation.
Fixes#15340.
When doing query for same topic names in a stream, we should do a
case-insensitive exact match for the topic, since that's the data
model for topics in Zulip.
This is a test case verifying the current codebase produces incorrect
results. All the messages should have been edited in this case
regardless of the topic's case unless they belong to a different
stream.

There seems to have been a confusion between two different uses of the
word “optional”:
• An optional parameter may be omitted and replaced with a default
value.
• An Optional type has None as a possible value.
Sometimes an optional parameter has a default value of None, or None
is otherwise a meaningful value to provide, in which case it makes
sense for the optional parameter to have an Optional type. But in
other cases, optional parameters should not have Optional type. Fix
them.

And then we still get the implicit assertion

This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.
This commit adds 'add_query_to_redirect_url' to one additional
function which had not yet been written when
'add_query_to_redirect_url' was introduced. This helper centralizes
URL manipulation for redirects, making it easier to add Pysa
sanitization in subsequent commits.
This new endpoint returns a 'user' dictionary which, as of now,
contains a single key 'is_subscribed' with a boolean value that
represents whether the user with the given 'user_id' is subscribed
to the stream with the given 'stream_id'.
Fixes#14966.
The only clients that should use the typing
indicators endpoint are our internal clients,
and they should send a JSON-formatted list
of user_ids.
We now enforce this, which removes some
complexity surrounding legacy ways of sending
users, such as emails and comma-delimited
strings of user_ids.
There may be a very tiny number of mobile
clients that still use the old emails API.
This won't have any user-facing effect on
the mobile users themselves, but if you type
a message to your friend on an old mobile
app, the friend will no longer see typing
indicators.
Also, the mobile team may see some errors
in their Sentry logs from the server rejecting
posts from the old mobile clients.
The error messages we report here are a bit
more generic, since we now just use REQ
to do validation with this code:
validator=check_list(check_int)
This also allows us to remove a test hack
related to the API documentation. (We changed
the docs to reflect the modern API in an
earlier commit, but the tests couldn't be
fixed while we still had the more complex
semantics for the "to" parameter.)
Currently there are no checks in validate_against_openapi_schema
to check whether the `content` it received actually matched with
the `response code`. For example during testing if a certain endpoint
was returning 400 but it was expected to return 200, then it would
pass schema validation as it would only have `msg` and `result` keys.
Add this validation and fix the wrong response returning points.
Add test to validate example responses in zulip.yaml. Also change
zulip.yaml for some wrong examples or for cases which were not
covered by `test-api`. Also enhance `validate_against_openapi_schema`.
Prevent `JsonableError(_("Missing content"))` from
ever being triggered.
That error wasn't handle by anything, and thus just threw a 500, as
it's not a response to an HTTP request.
The right fix is to adjust the caller to ban the empty string in
content (or content that strips to the empty string).
Closes#15145.
ACCESS_TOKEN_URL works a different for apple authentication, so,
we removed and remocked the ACCESS_TOKEN_URL mock in
`register_extra_endpoints` override of apple auth test class.
It is cleaner to have it as generic feature of `social_auth_test`.
So, this commit adds a function that returns token_data_dict that
we had earlier and is called in the ACCESS_TOKEN_URL mock.
This function is overriden in apple auth test class to generate
payload of the format that apple auth expects.

This commit adds some basic checks while adding or removing
realm owner status of a user and adds code to change owner
status of a user using update_user_backend.
This also adds restriction on removing owner status of the
last owner of realm. This restriction was previously on
revoking admin status, but as we have added a more privileged
role of realm owner, we now have this restriction on owner
instead of admin.
We need to apply that restriction both in the role change code path
and the deactivate code path.
This commit sets the role of the user creating the realm as
realm owner after the realm is created.
Previously, the role of user creating the realm was set as admin.
But now we want it to be owner because owners have the highest
privilege level.
The test_management_commands use in particular was causing pickling
errors when the test failed, because Python 3 filter returns an
iterator, not a list.

This was previously hardcoded with agreement between the Zulip backend
and frontend as 86400 seconds (1 day). Now, it's still hardcoded in
the backend, but arranged in a way where we could add a setting
without any changes to the mobile and terminal apps to update logic.
Fixes#15278.
This was implemented in 2012 to avoid showing a loading indicator for
fetching messages for users with no message history. However, the
Zulip onboarding UI always creates some message history, and fetching
history is fast, so this is likely clutter more than a useful
optimization.
This was written by Rishi for a very brief purpose a few years ago,
and it doesn't serve much purpose now other than to be a place we
update in code sweeps.
We're migrating to using the cleaner zulip.com domain, which involves
changing all of our links from ReadTheDocs and other places to point
to the cleaner URL.
Adds a top-level logger in `settings.LOGGING` `zulip.auth`
with the default handlers `DEFAULT_ZULIP_HANDLERS` and
an extra hanlder that writes to `/var/log/zulip/auth.log`.
Each auth backend uses it's own logger, `self.logger` which
is in form 'zulip.auth.<backend name>'.
This way it's clear which auth backend generated the log
and is easier to look for all authentication logs in one file.
Besides the above mentioned changes, `name` attribute is added to
`ZulipAuthMixin` so that these logging kind of calls wouldn't raise
any issues when logging is tried in a class without `name` attribute.
Also in the tests we use a new way to check if logger calls are made
i.e. we use `assertLogs` to test if something is logged.
Thanks to Mateusz Mandera for the idea of having a seperate logger
for auth backends and suggestion of using `assertLogs`.
Since owners have the highest privilege level, it made little sense to
sandwich them between administrators and guests.

This commit removes short_name and client_id fields from the user
objects returned by get_profile_backend because neither of them
had a purpose.
* short_name hasn't been present anywhere else in the Zulip API for
several years, and isn't set through any coherent algorithm.
* client_id was a forgotten 2013-era predecessor to the queue_id field
returned by the register_event_queue process.
The combination of these changes gets us close to having `get_profile`
have the exact same format as other endpoints fetching a user object.
This commit changes get_profile_backend to be based on format_user_row
such that it's a superset of the fields for our other endpoints for
getting data on a user.
To be clear, this does not removes any of the exisiting fields, that
were returned by this endpoint.
This change adds some fields to the User object returned by the
endpoint. API docs are updated accordingly for the added fields.
Slack owners and primary owners will be mapped to zulip

Old topic of the msg edit event can be used to help the client
calculate useful information such as if a change
in current narrow is required.
This fixes our re narrow logic after a stream edit of a topic, with
no change in topic name itself, since the original topic was not
present in the event received and hence the `orig_topic` was
undefined in this case.
This adds 'target_users' parameter to 'attempt_unsubscribe_of_principal`
function in test_subs.py, which accepts list of UserProfile objects to be
unsubscribed, instead of defining users in the function itself.
This change makes the code cleaner and more readable.
Also, 'other_user_subbed' parameter is changed to 'target_users_subbed'
to clearly depict the use of this parameter.
This commit extracts removing_someone_else logic to the function
'check_if_removing_someone_else' for better readability.

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

There's no reason to send data beyond the user `id` of the uploader,
and reason not to, as the previous model was both awkward when
`author=None` and resulted in unecessary parsing complexity for
clients.

This commit changes the person dict in event sent by do_change_user_role

to its ID. Because we had in-process caching of the immutable Client
objects, this isn't a material performance win, but it will eventually
let us delete that caching logic and have a simpler system.

This commit changes do_change_user_role to support adding or removing

We also extend the existing test for do_change_user_role to do a bit
more validation to confirm the audit log records all values of role.
The new realm_owner role is added as option for role field in
UserProfile model and is_realm_owner is added as property for the user
profile.
Aside from some basic tests validating the logic, this has no effect
as users cannot end up with set as realm owners.
If the key paramenter on POST isn't correct we won't be

We handle fenced code blocks in a preprocessor, and > style blockquotes
are parsed in a blockprocessor. Pymarkdown doesn't run the preprocessors
again on any blocks that it is parsing, and is unlikely to accept our
solution upstream; they intend to convert fenced_code to a block parser.
We simply run all the preprocessors on the text again, with the exception
of NormalizeWhitespace which removed delimiters used by HtmlStash to mark
preprocessed html code. To counter this, we subclass NormalizeWhitespace
and use our customized version for when it is called from a blockparser.

This commit merges do_change_is_admin and do_change_is_guest to a
single function do_change_user_role which will be used for changing
role of users.
do_change_is_api_super_user is added as a separate function for
changing is_api_super_user field of UserProfile.
This is important, because lack of this meant that the POST request in
our tests still had the old session, with various params stored in it.
This mechanism doesn't work in reality in SAML, so the backend uses
redis to store and recover the params from redis. Without flushing the
session, these tests would fail to catch some breakages in the
redis-based mechanism.
This will protect us in case of some kinds of bugs that could allow
making requests such as password authentication attempts to tornado.
Without restricting the domains to which the in-memory backend can
be applied, such bugs would lead to attackers having multiple times
larger rate limits for these sensitive requests.
