`cachify` is essentially caching the return value of a function using only
the non-keyword-only arguments as the key.
The use case of the function in the backend can be sufficiently covered by
`functools.lru_cache` as an unbound cache. There is no signficant difference
apart from `cachify` overlooking keyword-only arguments, and
`functools.lru_cache` being conveniently typed.

do_deactivate_user can't be run in an atomic block due to concerns
around revoking session in a transaction. See

Without the change in this commit, the process of deactivating a user
via SCIM is broken.
Adds and updates changelog documentation for
`POST /users/me/status` feature level 86 addition
of new emoji parameters.
Makes description text for emoji `reaction_type` consistent
throughout API documentation and also adds better description
of the `unicode_emoji` namespace.
Redirects emoji field links in `user_status` event to go to
the parameters in `/update-status` endpoint, which was not a
documented endpoint when the event documentation was created.
It's natural that someone might try a wrong password 5 times, and then
go through a successful password reset; forcing such users to wait
half an hour before typing in the password they just changed the
account to seems unnecessarily punitive.
Clear the rate-limit upon successful password change.
Removes `token_kind` parameter being passed to
`remove_apns_device_token` and `remove_android_reg_id` code
paths / endpoints. Possibly missed in a refactor of this
function as the tests for adding these tokens do not pass
a `token_kind` parameter.
Removes `zulip_org_id` and `zulip_org_kay` from code testing
`deactivate_remote_server`. These parameters are passed when
a remote server is added, so possibly a copy and paste error
when these tests were written / last refactored.
`update_realm_custom_profile_field` does not take `field_type`
as a parameter, so this removes it from any related tests.
Possibly these test parameters were missed in a refactor of this
endpoint / code.
`service_interface` is not a parameter of `add_bot_backend`, but
`interface_type` is, and that has the same default value as what
was being provided by the test, so updated for the parameter name
change, which was possibly missed in a previous code refactor.
`update_default_stream_group_info` was being passed `op` and
`group_name` in various tests, which are not implemented as
parameters for that endpoint / code path. So this removes those
from the existing tests. This is not a documented API endpoint,
so perhaps these were just overlooked when these tests were
written / last refactored.
If an API request specified a `client` parameter, we were
already prioritizing that value over parsing the UserAgent.
In order to have these parameters logged in the `RequestNotes`
as processed parameters instead of ignored parameters, we add
the `has_request_variables` decorator to `parse_client` and
then process the potential `client` parameter through the REQ
framework.

We remove the StackOverflow link because it is now so dated as to be
irrelevant -- it does not use `self.ident`, and cargo-cults the return
value of PyThreadState_SetAsyncExc.
As noted in the docstring for this function, the timeout is
best-effort only -- if the thread is blocked in a syscall, it will not
service the exception until it returns. It can also choose to catch
and ignore the TimeoutExpired; in either case it will still be running
even after the `timeout()` function returns.
Raising a vare TimeoutExpired it still somewhat accurate, but obscures
that the backend thread may still be running along merrily. Notice
such cases, and log a warning about them.
Having just thrown an exception into the thread, it is often useful to
know _what_ was the slow code that we interrupted. Raising a bare
TimeoutExpired here obscures that information, as any `exc_info` will
end there.
Examine the thread for any exception information, and use that to
re-raise. This exception information is not guaranteed to exist -- if
the thread didn't respond to the exception in time, or caught it, for
instance.
The quote in question originates in python/cpython@b8b6d0c2c6, when
the code was added. However, the code stopped having that comment,
and was no longer able to return anything but 1 or 0, starting in
python/cpython@4643c2fda1 -- Python 2.5.
Remove the block.
Reformats two events (`reaction op: add` and `reaction op:remove`)
to follow the general format of events in the OpenAPI that are
returned by the `/get-events` endpoint.
Removes unneeded reference to `EmojiBase` schema in `user_status`
return value for the `/register-queue` endpoint. Also, clarifies
the text about the `user_status` object and fields being returned.
Adds a non-endpoint specific page to the API documentation about
organization-level roles and permissions for users in order to
highlight important and useful information for clients and API
users.
Also, adds links to new documentation page in related areas
of the API documentation.
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.
Instead of using request.POST to get any potential `sender`
parameters for `send_message_backend`, moves it to the REQ
framework parameters as `req_sender`.
Also, updates `create_mirrored_message_users` to take specific
parameters instead of an HTTP request parameter, which then
accessed parameters via request.POST. And updates existing tests
for those changes.

Fix the stringification, make it case-insensitive, append with a dash

`disable-message-edit-history`: Remove text about EDITED label
and link to `view-a-messages-edit-history` instead.
`edit-or-delete-a-message`: Reformat 'EDITED' and '(deleted)'
to be bold instead of using backticks. Make link to view
edit history clearer.
Note that the text used in the `OpenGraphTest` in
`test_middleware.py` had to be updated for the changes to
`disable-message-edit-history`.
This avoids an error when a user has already muted the new topic name.
We do this by ignoring duplicates, rather than catching the
IntegrityError, because this edit happens in a transaction, and that
would abort the transaction.
This is necessary for the migration 0386_fix_attachment_caches to run,
and likely makes more convenient any future parallel code interacting
with both Attachment and ArchivedAttachment.
Our original implementation of moving muted topic records when a topic
is moved took a shortcut of treating all change_later usage as
something with intent to move the whole topic.
This works OK when moving the whole topic via this interface, but not
when moving a last off-topic message in the topic.
Address this by changing the rule to match the existing
moved_all_visible_messages variable.
Adds tab for web-public streams in documentation for setting
who can create new streams, as well as some text about why
this is limited to certain roles.
Removes list of actions that can be restricted to full members
due to maintainability concerns for that type of list in the
documentation and replaces it with a short descriptive text
explaining that many settings in Zulip support this restriction.
This migration needs to be run after the previous commit is deployed
to a given Zulip installation, to fix any stale values of
is_realm_public and is_web_public.
Previously, Attachment.is_realm_public and its cousin,
Attachment.is_web_public, were properties that began as False and
transitioned to True only when a message containing a link to the
attachment was sent to the appropriate class of stream, or such a link
was added as part of editing a message.
This pattern meant that neither field was updated in situations where
the access permissions for a message changed:
* Moving the message to a different stream.
* Changing the permissions for a stream containing links to the message.
This correctness issue has limited security impact, because uploaded
files are secured both by a random URL and by these access checks.
To fix this, we reformulate these fields as a cache, with code paths
that change the permissions affecting an attachment responsible for
setting these values to the `None` (uncached) state. We prefer setting
this `None` state over computing the correct permissions, because the
correct post-edit permissions are a function of all messages
containing the attachment, and we don't want to be responsible for
fetching all of those messages in the edit code paths.
When the credentials are provided by dint of being run on an EC2
instance with an assigned Role, we must be able to fetch the instance
metadata from IMDS -- which is precisely the type of internal-IP
request that Smokescreen denies.
While botocore supports a `proxies` argument to the `Config` object,
this is not actually respected when making the IMDS queries; only the
environment variables are read from. See
https://github.com/boto/botocore/issues/2644
As such, implement S3_SKIP_PROXY by monkey-patching the
`botocore.utils.should_bypass_proxies` function, to allow requests to
IMDS to be made without Smokescreen impeding them.

`prepare_linkifier_pattern`, as of db934be064, adds a match to the
end of the regex, of either the end of string, or a non-word character
-- this is in place of a negative look-ahead, which is no longer
possible in re2. This causes the regex to consume trailing
whitespace, and thus not be able to match twice in succession with
`pattern.finditer` -- "#1234#5678" fails to match because the space
is consumed by the first match of the regex.
Rather than use `pattern.finditer`, write own own version, which
rewinds over the non-word character consumed after the match, if any.
This allows the same "after" non-word character to also satisfy the
"before" of the next match.
Fixes#21502.
Extends the linking to Zulip documentation to cover:
- Getting URLs to messages via the message timestamp.
- Getting links to topics via the three-dots menu.
- Getting links to streams via right-click context menu.
Creates a new tabbed section for using the browser
address bar to copy URLs.
* Don't print the empty list for the vast majority of realms where
this is a noop.
* Make output a little more clear that this isn't revoking all
Confirmations, just those associated with deactivated users.
Add support for moving MutedTopic entries to another stream where
the user has access to shared history in both streams and
`propagate_mode != "change_one"`.
Also, we delete them the current user does not have access to the
target stream.
This is intended for rare situations where one is creating multiple
realms via a script.
After all the preparatory refactoring in this last several commits, we
can now provide a working implementation of a create_realm management
command.
We set nocoverage for the new function. Ideally it'd eventually get an
automated test, but we don't want to block this helpful refactoring on
doing so.
We remove a bit of error handling for cases where someone provided
only one of the email and full name parameters, with the benefit of
this being a lot cleaner.
We now call this function inside do_create_user(...,
realm_creation=True), which generally improves readability and
robustness of the codebase.
This fixes a bug where this onboarding content was not correctly done
when creating a realm via LDAP, and also will be important as we add
new code paths that might let you create a realm.
This improves robustness of any code paths calling do_create_realm,
which previously needed to call this correctly to achieve the same
results as creating a user via the UI.
This also fixes a bug where this code was not called if a realm were
created using the LDAP code path.
This parameter was introduced in
ea11ce4ae6, and no longer serves a
purpose. Zulip will already correctly record that the user has not
agreed to ToS, and either prompt them on first login or not depending
whether the server is configured to require ToS.
This is an important design detail, so we document this aspect of
creating users via both the management command and API code paths with
an explicit parameter value and comment.
Ordinary organization administrators shouldn't be allowed to change
ownership of a bot with the can_create_users permission.
This is a special permission that is granted manually by server
administrators to an organization (to a UserProfile of the org owners'
choice) after approval by a server administator. The code comments
provide more detail about why this is sensitive.
The BigBlueButton integration had a problem with generating
the random password with only 12 characters. This would
cause the attendeePW to be the same as the moderatorPW,
which might be fine but seems like something that could be an
error in a future version of BigBlueButton.
The name for a BigBlueButton meeting is now generated from the stream
name and topic name.
The createTime option is used to have the user redirected to a link
that is only valid for this meeting.
Even if the same link in Zulip is used again, a new createTime
parameter will be created, as the Meeting on the BigBlueButton server
has to be recreated.
Fixes#16498.

Fixes#20804.
Previously, when a topic was edited (including being resolved), it
would become unmuted for any users who had muted it, which was
annoying.
While it's not possible to determine the user's intent completely,
this is clearly incorrect behavior in the `change_all` case, such as
resolving a topic.
The comments discuss some scenarios where we might want to enhance
this further, but this is the best we can do without large increases
in complexity.
Fixes#15210.

he possibility for it being null was likely an oversight -- it should

when it was added.
We've confirmed there are no existing violations of this invariant in
Zulip Cloud.
This is a natural follow-up to

This commit adds the backend functionality to
mark messages as unread through update_message_flags
with `unread` flag and `remove` operation.
We also manage incoming events in the webapp.
Tweaked by tabbott to simplify the implementation and add an API
feature level update to the documentation.
This commit was originally drafted by showell, and showell
also finalized the changes. Many thanks to Suyash here for
the main work here, which was to get all the tests and
documentation work moving forward.
This commit creates a new TypedDict RealmPlaygroundDict for realm
playground objects. Now the list of playgrounds in the events sent
to clients and the "added_playground" field of RealmAuditLog entry
use RealmPlaygroundDict instead of Dict.
This commit modifies the notify_realm_playgrounds function to accept
realm_playgrounds as argument from the caller instead of computing it
in the function to avoid duplicate queries since the realm playgrounds
list will be required in its caller functions as well in further commits.
Clearing the sessions inside the transaction makes Zulip vulnerable to
a narrow window where the deleted session has not yet been committed,
but has been removed from the memcached cache. During this window, a
request with the session-id which has just been deleted can
successfully re-fill the memcached cache, as the in-database delete is
not yet committed, and thus not yet visible. After the delete
transaction commits, the cache will be left with a cached session,
which allows further site access until it expires (after
SESSION_COOKIE_AGE seconds), is ejected from the cache due to memory
pressure, or the server is upgraded.
Move the session deletion outside of the transaction.
Because the testsuite runs inside of a transaction, it is impossible
to test this is CI; the testsuite uses the non-caching
`django.contrib.sessions.backends.db` backend, regardless. The test
added in this commit thus does not fail before this commit; it is
merely a base expression that the session should be deleted somehow,
and does not exercise the assert added in the previous commit.

These error messages weren't marked for translation.
DEACTIVATED_ACCOUNT_ERROR and PASSWORD_TOO_WEAK_ERROR are used in
several places and imported, so we can't move them to be in-line errors
and we keep them at top-level, marked with gettext_lazy.
Using mark_safe on errors with content in them taken from user-input is
a clearly bad idea. With that said, this code
was not exploitable in the current state, given that username is a value
you have to POST to /login/, and the endpoint is CSRF-protected.
We also remove use of mark_safe from the errors without user input them,
but that are just plaintext and thus don't need it.
Adds documentation for admins to manage users via the user profile
modal for these actions:
- Deactivating a user
- Changing a user's role
- Changing a user's name
Creates two new tab sections because we still want to document
the ability to do these actions through the users section in
the organizational settings modal.
Also cleans up some text in the help center article for changing
a user's role.

This commit adds a cron job which runs every hour to add the users to
full members system group if user is promoted to a full member.
This should ensure that full member status is available no more than
an hour after configuration suggests it should be.
There can be cases when system groups data is not present while
importing, like when importing from other products, so this
commit adds code to create system user groups and add users to
it according to their role.
This commit adds users to the appropriate system user group
based on their role. We also change the user groups when
changing role of the user.
We also add migration to add existing users to the appropriate
user groups.
This commit adds update_users_in_full_members_system_group which
is currently used to update the full members group on changing
role of a user. This function will be modified in next commit such
that it can be used to update full members group on changing
waiting_period_threshold setting of realm.
We pass list of user ids instead of user profile objects to
remove_members_from_user_group. We still need to call user_id_to_users
in the views function instead of directly passing the ids to
remove_members_from_user_group to make sure we check whether all
ids are valid or not.
We pass list of user ids instead of user profile objects to
bulk_add_members_to_user_group. We still need to call user_id_to_users
in the views function instead of directly passing the ids to
bulk_add_members_to_user_group to make sure we check whether all
ids are valid or not.
Previous behavior was logging only the uuid if it was provided by the
remote server, but that's insufficient, because the user may actually
have no devices registered with uuis and we (at the bouncer) end up
sending notifications to id-based registrations. Not having that id
logged makes it impossible to figure out what's going on.
Fixes#18017.
In previous commits, the change to the bouncer API was introduced to
support this and then a series of migrations added .uuid to
UserProfiles.
Now the code for self-hosted servers that makes requests
to the bouncer is changed to make use of it.
This is in a separate commit to make deployment easier. It ensures that
this is only marked non-null after the backfill migration (backfilling
.uuid for all old UserProfiles) runs - which was added in the previous
commit.
This is the first step to making the full switch to self-hosted servers
use user uuids, per issue #18017. The old id format is still supported
of course, for backward compatibility.
This commit is separate in order to allow deploying *just* the bouncer
API change to production first.
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.
This will make it convenient to add a handful of organizations to the
beta of this feature during its first few weeks to try to catch bugs,
before we open it to everyone in Zulip Cloud.
The correct return type of get_realm_domains should
be List[Dict[str, Union[bool, str]]] instead of
List[Dict[str, str]] because allowed_subdomains is
a bool field not str.
A user can subscribe to a stream and sometimes (depending
on stream permissions) see messages from the stream
that were sent before they subscribed, and that user
won't have a UserMessage row for that message.
In order to do things like star a message, we need
to create UserMessage records on the fly.
In the past we wisely constrained this logic to the
specific use cases. But I think we can generalize
the logic now. For example, we are now building a
feature to mark messages as unread, and it motivates
the same need to auto-create UserMessage rows.
So now we handle this in a more generalized fashion.
Refactors and cleans up the shared `MessagesBase` schema in
the OpenAPI so that it accurately reflects the general base
for message objects for endpoints that use it as a reference.
A follow-up to adding `edit_history` as a property of message
objects. And a prepartory commit for `GET /messages/{msg_id}`
to return not only the raw content of the message but also
the message object.
When removing notifications, we skip the access control on if the user
still can read them -- they should not have a notification of them,
both because they currently cannot read the message, as well as
because they have already done so.
Translators found it confusing, since it's not at all obvious that the
word "quote" should not be translated.
I'm not altogether happy with the code formatting for this.
While we're changing this, also standardize on the "```` quote" style
of quote blocks to ensure code/quote blocks in stream descriptions are
unlikely to conflict with this syntax.
In steady-state, requests to FCM take about a second; however, in
cases where the remote FCM server is unstable, the request has been
observed to block for more than a minute.
As noted in the previous commit, pushes must complete within 30s;
fail fast, and let the retries and exponential backoff handle errors.
The worst-case total time taken with timeouts and errors for an FCM
notification is 19.5s. Unfortunately, `aioapns` does not appear to
have any timeouts, and thus this commit cannot guarantee a total of
fewer than 30s.
This reverts bc15085098 (which provided
not justification for its change) and moves further, down to 2 retries
from the default of 5.
10 retries, with exponential backoff, is equivalent to sleeping 2^11
seconds, or just about 34 minutes (though the code uses a jitter which
may make this up to 51 minutes). This is an unreasonable amount of
time to spend in this codepath -- as only one worker is used, and it
is single-threaded, this could effectively block all missed message
notifications for half an hour or longer.
This is also necessary because messages sent through the push bouncer
are sent synchronously; the sending server uses a 30-second timeout,
set in PushBouncerSession. Having retries which linger longer than
this can cause duplicate messages; the sending server will time out
and re-queue the message in RabbitMQ, while the push bouncer's request
will continue, and may succeed.
Limit to 2 retries (APNS currently uses 3), and results expected max
of 4 seconds of sleep, potentially up to 6. If this fails, there
exists another retry loop above it, at the RabbitMQ layer (either
locally, or via the remote server's queue), which will result in up to
3 additional retries -- all told, the request will me made to FCM up
to 12 times.
This model is by designed intended to exist on a 1:1 relationship with
Realms, and we attempt to ensure that with application code, but we
should have a unique constraint too, since a database with duplicate
such entries would be corrupted.
We do this via the standard Django OneToOneField.
It was there to work around https://bugs.python.org/issue17519. This
workaround with del seems like a partial improvement.

Now that we have code to support reading prev_topic, this is no longer
necessary.
We'll want to deploy this change to production before running the
migration to remove prev_subject from edit history entries, so that
prev_subject can be fully purged from the database.
We modify the message_edit_history marshalling code so that this
commit does not change the API, since we haven't backfilled the data
yet.
FormattedEditHistoryEvent, introduced in the previous commit, doesn't
directly inherit fields from EditHistoryEvent, so no changes are
required there.
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.

These types will help make iteration on this code easier.
Note that `user_id` can be null due to the fact that
edit history entries before March 2017 did not log
the user that made the edit, which was years after

Moves the encodeHashComponent and decodeHashComponent functions out of
hash_util and into internal_url which belongs to shared. This is to
accommodate sharing of this code with mobile or any other codebases that
do not wish to duplicate logic.
TestMaybeSendToRegistration needs tweaking here, because it wasn't
setting the subdomain for the dummy request, so
maybe_send_to_registration was actually running with realm=None, which
is not right for these tests.
Also, test_sso_only_when_preregistration_user_exists was creating
PreregistrationUser without setting the realm, which was also incorrect.
create_preregistration_user is a footgun, because it takes the realm
from the request. The calling code is supposed to validate that
registration for the realm is allowed
first, but can sometimes do that on "realm" taken from something else
than the request - and later on calls create_preregistration_user, thus
leading to prereg user creation on unvalidated request.realm.
It's safer, and makes more sense, for this function to take the intended
realm as argument, instead of taking the entire request. It follows that
the same should be done for prepare_activation_url.
In these tests, the code ends up with a logged in session when it's
undesired - later on these tests make requests to a different subdomain
- where a logged in session is not supposed to exist. This leads to an
unintended, strange situation where request.user is a user from the old
subdomain but the request itself is to a *different* subdomain. This
throws off get_realm_from_request, which will return the realm from
request.user.realm - which is not what these tests want and can lead to
these tests failing when some of the production code being tested
switches to using get_realm_from_request instead of
get_realm(get_subdomain).
The codepaths for joining an organization via a multi-use invitation
(accounts_home_from_multiuse_invite and maybe_send_to_registration)
weren't validating whether
the organization the invite was generated for matches the organization
the user attempts to join - potentially allowing an attacker with access
to organization A to generate a multi-use invite and use it to join
organization B within the same deployment, that they shouldn't have
access to.
The database value for expiry_date is None for the invite
that will never expire and the clients send -1 as value
in the API similar to the message retention setting.
Also, when passing invite_expire_in_days as an argument
in various functions, invite_expire_in_days is passed as
-1 for "Never expires" option since invite_expire_in_days
is an optional argument in some functions and thus we cannot
pass "None" value.
A migration should not import zerver.lib.streams at all, but this
solves the immediate problem with check-database-compatibility.py.

Removes `client` parameter from backend tests using the
`POST /messages` endpoint when the test can use the default
`User-Agent` as the client, which is set to `ZulipMobile` for API
requests and a browser user agent string for web app requests.
Various tests use the `PATCH /stream/{stream_id} endpoint in
`test_subs.py`. Because the stream id is in the URL path, it
does not also need to be passed as a query parameter.
Removes instances of `stream_name` being passed as a query
parameter to tests.
Removes `topic_name` parameter in `test_message_flags.py`
where is being passed to a test for marking a stream as
read because it is an ignored parameter for that endpoint.
This was only used for upgrading from Zulip < 1.9.0, which is no
longer possible because Zulip < 2.1.0 had no common supported
platforms with current main.
If we ever want this optimization for a future migration, it would be
better implemented using Django merge migrations.

After failing to notice a place where we wanted to hide timezone
information, we decided to add timezones to some of the test
users, so that we can better consider the effects of timezones
when manually testing.
Testing:
* ran populate_db and confirmed users had timezones in the UI
* updated test_populate_db.py
Adds `realm_web_public_access_enabled` as a realm-specific server
setting potentially returned by the `/get-server-settings` endpoint
so that clients that support browsing of web-public stream content
without an account can generate a login page that supports that
type of access.
Various backend tests use the `PATCH /messages/{msg_id}` endpoint.
For that endpoint, the message ID is encoded in the URL path and
ignored if provided as a parameter in the the query.
Verified that the tests were providing the same message ID to both
the path and then removed the ignored parameter in the query.
This commit refactors get_user_by_email function
to use access_user_by_email which is similar to
already existing access_user_by_id and thus using
get_user_data function added recently.
We also remove the unnecessary check for email as
email will always be passed to this endpoint.
Preparatory commit for #10970.
This commit adds get_user_data which is called by
get_members_backend to compute the client_gravatar
value and then return the data of a single user or
all accessible users.
This function will also be used by get_user_by_email
in further commtis.
When pulling batches out of the ScheduledEmail list in a single
transaction, an unexpected failure to send an email will result in the
whole batch getting retried. This will result in infinite email
sending loops.
Pull a single row off at a time and send it. We continue without
retries to the next email on EmailNotDeliveredException, but will
retry infinitely on other exceptions.
Fixes: #20943.
Putting all of the logic in a `finally` block is equivalent to a bare
`except` block, which silently consumes all exceptions.
Move only the most-necessary parts into the except; this lets
`BadImageError` exceptions from `zerver/lib/upload.py` to escape,
allowing better the generic "Image file upload failed" to be replaced
with a more specific message.
It also allows unexpected exceptions, as the previous commit resolved,
to escape and 500. This lets them be detected and resolved, rather
than give users a silently bad experience.
5dab6e9d31 began honoring the list of disposals for every frame.
Unfortunately, passing a list of disposals for a non-animated image
raises an exception:
```
File "zerver/lib/upload.py", line 212, in resize_emoji
image_data = resize_gif(im, size)
File "zerver/lib/upload.py", line 165, in resize_gif
frames[0].save(
File "[...]/PIL/Image.py", line 2212, in save
save_handler(self, fp, filename)
File "[...]/PIL/GifImagePlugin.py", line 605, in _save
_write_single_frame(im, fp, palette)
File "[...]/PIL/GifImagePlugin.py", line 506, in _write_single_frame
_write_local_header(fp, im, (0, 0), flags)
File "[...]/PIL/GifImagePlugin.py", line 647, in _write_local_header
disposal = int(im.encoderinfo.get("disposal", 0))
TypeError: int() argument must be a string, a bytes-like object or a
number, not 'list'
```
`check_add_realm_emoji` calls this as:
```
try:
is_animated = upload_emoji_image(image_file, emoji_file_name, a
uthor)
emoji_uploaded_successfully = True
finally:
if not emoji_uploaded_successfully:
realm_emoji.delete()
return None
# ...
```
This is equivalent to dropping _all_ exceptions silently. As such,
Zulip has silently rejected all non-animated images larger than 64x64
since 5dab6e9d31.
Adjust to only pass a single disposal if there are no additional
frames. Add a test for non-animated images, which requires also
fixing the incidental bug that all GIF images were being recorded as
animated, regardless of if they had more than 1 frame or not.
The deferred_work events can't be processed in the test suite
environment, since it tries to make requests to the host <realm.uri>
which is "zulip.testserver" and obviously not going to work. Since the
test suite base data set has no animated emoji, there's nothing to do,
and we can skip this step.
This code only runs when applying the migration to an already
provisioned test db - because during an initial db set up there are no
realms yet, so no events get pushed by the migration.
The previous random strategy for picking 5 emails would result in
collisions in 1 out of 10000.35 tests, leading to
psycopg2.errors.UniqueViolation.

A recent Postgres upstream release appears to have broken PGroonga.
While we wait for https://github.com/pgroonga/pgroonga/issues/203 to

Sometimes we may get data to import, due to export bugs, malformed data

The tool needs to run this function, since it uses django's send_email
directly instead of going through our zerver.lib.send_email.send_email
codepath.
The message ID is encoded in the URL, not the PATCH parameters, so
this argument was ignored. I verified that it appears to have always
matched the value present in the URL.
The new logic better matches reasonable user expectations, that if you
move all the messages, that's a whole-topic move, regardless of which
propagation mode you selected.
When moving only part of a topic, it's useful to display that
information to users in these notifications so that it's clear what's
happening.
The most important consequence is actually just increasing confidence
that when you see that the whole topic was moved, that's accurate.
Substantially modified by tabbott.
Fixes#20575.
To avoid an uncaught IntegrityError causing a 500 HTTP response in a
race between two processes trying to mute a topic, we catch the
integrity error and raise the error exception with status 400 we'd
have gotten if the second request had been a bit later.
Fixes#21011.
The S3 backend implementation of upload_emoji_image was accessing
emoji_file.name - which is redundant because emoji_file_name already
gets passed in and can be used, and an object of type IO[bytes] may not

Fixes#20132.
EMAIL_HOST_USER without EMAIL_HOST_PASSWORD is not going to be a valid
configuration, and may result from making mistake in correctly setting
it in the secrets file and end up being a non-obvious cause of failure
to send email. Logging an error will be useful for detecting it. Further
conditions can be added to the function in the future.
Calling `get_apns_context` opens (and caches) an open connection to
the APNs servers. Since `apns_enabled` is called from Django
codepaths, this means that the Django processes hold unnecessary
connections open to the APNs servers.
Switch `apns_enabled` to checking what `get_apns_context` checks when
we're just returning True/False.

The new release adds the commit:
20ac22b96d
Which allows us to get rid of the entire ugly override that was needed
to do this commit's job in our code. What we do here in this commit:
* Use django-scim2 0.17.1
* Revert the relevant parts of f5a65846a8
* Adjust the expected error message in test_exception_details_not_revealed_to_client
since the message thrown by django-scim2 in this release is slightly
different.
We do not have to add anything to set EXPOSE_SCIM_EXCEPTIONS, since
django-scim2 uses False as the default, which is what we want - and we
have the aforementioned test verifying that indeed information doesn't
get revealed to the SCIM client.

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.
As a preparatory step to refactoring json_success to accept
request as a parameter, change `do_report_error`, which is
called from the events queue for "error_reports", to return
None instead of json_success.
Adds an assertion error to `ErrorReporter` queue processor
and removes `JsonableError` from `do_report_error`.
It is likely that `do_error_report` was moved from a view in a
previous refactor, but was not updated to no longer return an
HttpReponse.
As a preparatory step to refactoring json_success to accept
request as a parameter, update helper function `compose_views`
in `views.streams.py` to return the response data and call
json_success from view functions that utilize `compose_views`.
Also, updates related test in `zerver.tests.test_subs.py`.
As a preparatory step to refactoring json_success to accept
request as a parameter, change interface of helper functions:
`handle_deferred_message` in `views.message_send.py` and
`mute_topic` and `unmute_topic` in `views.muting.py`, so
that they return None or data for json_success.
Instead call json_sucess in the caller function, which already
has the HttpRequest as a parameter.
Adds a check for `additionalProperties: true` when there are no
properties listed in the schema.
This currently only happens in one place, but will be helpful for
deduplicating text between the `register-queue` and `get-events`
endpoints.
Wordle has recently become a thing and it uses green, yellow and white (or
black in dark mode) large square unicode characters to let people share their
gameplay. Zulip converts the white and black large square unicode characters to
emojis, but not the green and yellow ones. This causes the Wordle grid to be
misaligned when shared on Zulip.
This commit adds green and yellow large square emojis to our emoji list to fix
the problem.
Previously, we only checked mandatory_topics setting before
sending message in frontend and there was no restriction in
backend. This commit adds the check in backend also making
sure messages without topic cannot be sent through API as
well if mandatory_topics setting is set to True.
Previously, users found it annoying that the automated "Resolve topic"
notifications triggered an unread for everyone in the stream; this
discouraged some users from using the feature on older threads for
fear of being annoying. We change this to a better default, of only
users who participated in the topic (via either messages or reactions)
being eligible for the new message being unread.
We will likely want to create global and stream-level notifications
settings to control this behavior as a follow-up -- some users, like
me, might prefer the simpler "Always unread" behavior in some streams.
Note that the automated notifications that a topic was resolved will
still result in the topic being moved to the top of the left sidebar.
This would be somewhat difficult to change, since the left sidebar
algorithm just looks at the highest message ID in the topic.
Fixes#19709.

There are three user settings that are integer enums:
`color_scheme`, `demote_inactive_streams` and
`desktop_icon_count_displays`.
Unlike the other user settings, these were using the `content`
keyword instead of the `schema` keyword in their definitions,
which caused them not to be rendered correctly in the api
documentation.
Changes the keyword to `schema` and fixes the indentation
for these three user settings in the two endpoints using
them.
Removes various instances of quotation marks that are not needed,
specifically looking at instances of arrays, e.g. `- "`, in the
OpenAPI documentation.
The target realm was not being passed to create_attachment in
upload_message_file implementations. This was a bug in the edge-case of
cross-realm messages - in particular, causing a bug in the email
gateway:
When an email with an attachment is sent, the message is mirrored to
Zulip with Email Gateway Bot as the message sender and uploader of the
attachment. Due to the realm not being passed to create_attachment, the
Attachment would get created with .realm being the system bot realm,
making the attachment inaccessible under some conditions due to failing
the following condition check (that's expected to pass, provided that
the .realm is set correctly):
```
if (
attachment.is_realm_public
and attachment.realm == user_profile.realm
and user_profile.can_access_public_streams()
):
# Any user in the realm can access realm-public files
return True
```
Fixes the rendering of enums to show strings with quotation marks,
while integers will continue to be rendered without quotation marks.
This allows for an empty string to be passed as an enum value and be
rendered as such in the documentation. Null will be rendered without
quotation marks, like integer values.
Makes `edit_timestamp` and `user_id` required fields for all
`update_message` events.
Adds `rendering_only` as another required field to signal if
events are only updating the rendered content of the message,
which is currently the case for adding inline url previews.
Updates `test_event.py` so that `do_update_message` and
`do_update_embedded_data` refer to the same testing schema
for `update_message` events, and therefore reflect the same
required fields for the `update_message` event.
The OpenAPI definition for `update_message` events is also
updated to reflect the required field and descriptions of
various properties are updated for the addition of the
`rendering_only` property.
Moves details about the rate limit error object and handling to
the OpenAPI documentation description for that common error.
Previously, this information was on the general rest error
handling documentation page without clear connection to the
specific rate limit error.
Fixes a typo in the changelog (feature 36) for that same error
and also fixes a misplaced colon in the description of the error
for missing request parameters.
Adds detailed definition of objects in the `subscription_data` parameter
array for the `/update-subscription-settings` endpoint.
Fixes#20825. Follow-up to #20409.
Formats and moves whether a field of an object in a request

documentation.
Follow up to #20409.

The change to curl_param_value_generators.py warrants a brief
explanation. Stream permission changes now generate a notification
message. Our curl example test for removing a reaction comes after
the two tests for updating the stream permission changes, thus the
hardcoded message ID in that test needs to be incremented by 2 to
account for the two notification messages that now come before it.
This is a part of #20289.

revoke_invites_generated_by_user should send invites_changed event if it
actually revokes some invitations. This is called in the user
deactivatoin codepath.
Event of type "realm_user", op "remove", emitted by do_deactivate_user
should remove the user id from subscriptions in the state. We weren't
catching this bug, because test_do_deactivate_bot uses a newly created
bot, so no stream subscriptions are affected. The bug shows up if
deactivating e.g. cordelia - thus we want to have two tests instead,
one for testing bot deactivation and one for user deactivation.
We now use recipient_id % 24 for new stream colors
when users have already used all 24 of our canned
colors.
This fix doesn't address the scenario that somebody
dislikes one of our current canned colors, so if a
user continually changes canned color N to some other
color for new streams, their new streams will continue
to include color N (and the user will still need to
change them).
This fix doesn't address the fact that it can be expensive
during bulk-add situations to query for all the colors
that users have already used up.

The limit here is purely to prevent breakage in case of a pathological
number of images in a single message; 5 images is entirely possible in
a reasonable message, and causes user confusion when they are not

using the link they've created for themselves.
do_revoke_user_invite and do_revoke_multi_use_invite were using objects

should avoid that. The function was only using the .realm attribute of
the received objects, so it's simpler to make it just take realm as its

An explanatory note on the changes in zulip.yaml and
curl_param_value_generators is warranted here. In our automated
tests for our curl examples, the test for the API endpoint that
changes the posting permissions of a stream comes before our
existing curl test for adding message reactions.
Since there is an extra notification message due to the change in
posting permissions, the message IDs used in tests that come after
need to be incremented by 1.
This is a part of #20289.
Prior to this commit, we wrapped all incoming messages from Slack
in backticks. This led to weird formatting errors when an incom-
ing message from Slack contains backticks, to refer to a function
name, for instance.
Moves `flags` field to top part of object description because
it is always included in the event.
If a field is present only for certain types of message updates,
the description begins by stating when the field is present:
"Only present if ...".
These fields are organized by the type of message update:
stream, stream and/or topic, topic, content.
If a field is not present due to a special event, the description
ends by stating when the field is not present:
"Not present if ...".
Adds documentation for fields currently required to be returned
with any `update_message` event.
do_delete_users had two bugs:
1. Creating the replacement dummy users
with active=True
2. Creating the replacement dummy users with email domain set to
realm.uri, which may not be a valid email domain.
Prior commits fixed the bugs, and this migration fixes the pre-existing
objects.
Otherwise the dummy user can be created with an invalid email domain -
e.g. in development environment with the domain
"@http://localhost:9991". get_fake_email_domain exists exactly for
handling these kinds of scenarios.
Stop using `access_user_group_by_id` in notifications codepaths, as it
is meant to be used to check for _write_ access, not read
access (which is not limited). In the notification codepaths, there
are no ACLs to apply, and the ID is known-good; just load it
directly. The `for_mention` flag is removed, as it was not used in the
mention codepaths at all, only the notification ones.
get_remote_server_by_uuid (called in validate_api_key) raises
ValidationError when given an invalid UUID due to how Django handles
UUIDField. We don't want that exception and prefer the ordinary
DoesNotExist exception to be raised.
APNs payloads nest the zulip-custom data further than the top level,
as Android notifications do. This led to APNs data silently never
being truncated; this case was not caught in tests because the mocks
provided the wrong data for the APNs structure.
Adjust to look in the appropriate place within the APNs data, and
truncate that.
This replaces the temporary (and testless) fix in
24b1439e93 with a more permanent
fix.
Instead of checking if the user is a bot just before
sending the notifications, we now just don't enqueue
notifications for bots. This is done by sending a list
of bot IDs to the event_queue code, just like other
lists which are used for creating NotificationData objects.
Credit @andersk for the test code in `test_notification_data.py`.
As explained in the comments in the code, just doing UUID(string) and
catching ValueError is not enough, because the uuid library sometimes
tries to modify the string to convert it into a valid UUID:
>>> a = '18cedb98-5222-5f34-50a9-fc418e1ba972'
>>> uuid.UUID(a, version=4)
UUID('18cedb98-5222-4f34-90a9-fc418e1ba972')
This diff looks slightly noisy, but the main chunk of
code that we moved here has the same logic as before,
and it just gets realm_id from MentionBackend now, instead
of having our markdown processor have to supply it.
We basically want MentionData to be the gatekeeper of
mention data, and then we delegate backend tasks to
MentionBackend.
Soon we will add a cache to MentionBacked, which will
justify this change a bit more.
We now make it mandatory to pass in the Realm object.
If this function was ever called with None, I am scared
to know what the expected results were at the time of
writing.
It's slightly annoying to plumb Optional[MentionBackend]
down the stack, but it's a one-time change.
I tried to make the cache code relatively unobtrusive
for the single-message use case.
We should be able to eliminate redundant stream queries
using similar techniques.
I considered caching at the level of rendering the message
itself, but this involves nearly as much plumbing, and
you have to account for the fact that several users on
your realm may have distinct default languages (French,
Spanish, Russian, etc.), so you would not eliminate as
many query hops. Also, if multiple streams were involved,
users would get slightly different messages based on
their prior subscriptions.
When our handlers specifically reference self.md.zulip_db_data,
we now use an explicit type.
We probably want a more robust solution here, such as a semgrep
rule.
We now serialize still_url as None for non-animated emojis,
instead of omitting the field. The webapp does proper checks
for falsiness here. The mobile app does not yet use the field
(to my knowledge).
We bump the API version here. More discussion here:

Appending to bytes in a loop leads to a quadratic slowdown since
Python doesn’t optimize this for bytes like it does for str.

While accepting an invitation from a user, there was no condition in
place to check if the user sending the invitation was now
now-deactivated.
Skip sending notifications about newly-joined users to users who are
now disabled.
Fixes#18569.
We don't have to go to the database to get the Recipient
fields for `user_profile.recipient`.
See also 85ed6f332a from a little
over a year ago--it's very similar.
The bug here probably didn't come up too much in
practice, but if we were adding a user to multiple
streams when they already had used all N available
colors, all the new streams would be assigned the same
color, since the size of used_colors would stay at N,
thwarting our little modulo-len hackery.
It's not a terrible bug, since users can obviously
customize their stream colors as they see fit.
Usually when we are adding a user to multiple streams,
the users are fairly new, and thus don't have many
existing streams, so I have never heard this bug
reported in the field.
Anyway, assigning the colors in bulk seems to make more
sense, and I added some tests.
For the situations where all the colors have already
been used, I didn't put a ton of thought into exactly
which repeated colors we want to choose; instead, I
just ensure they're different modulo 24. It's possible
that we should just have more than 24 canned colors, or
we should just assign the same default color every time
and let users change it themselves (once they've gone
beyond the 24, to be clear). Or maybe we can just do
something smarter here. I don't have enough time for a
deep dive on this issue.
Part of our codepath for subscribing users involves
fetching the users' existing subscriptions to make sure
we can do things like properly report to the clients
that the users were already subscribed. This codepath
used to be coupled to code that helped users maintain
unique stream colors.
Suppose you are creating a new stream, and you are
importing users from an older stream with 15k
subscribers, and each of your users is subscribed to
about 20 streams.
The prior code, instead of filtering on recipient_id,
would literally look at every subscription for every
user, which was kind of crazy if you didn't understand
the pick-stream-color complications.
Before this commit, we would fetch 300k rows with 15
columns each (granted, all but one of the columns are
bool/int). That's a total of 4.5 million tiny objects
that we had to glom into Django ORM objects and slice
and dice.
After this commit, we would fetch exactly zero rows
for the are-they-already-subscribed logic.
Yes, ZERO.
If we were to mistakenly try to re-add the same 15k
subscribers to the new stream (under the new code), we
will now fetch 15k Sub rows instead of 300k.
It is worth looking at the prior commit. We go through
great pains to ensure that users get new stream colors
when we invite them to a stream, and we still fetch a
bunch of data for that. Instead of 4.5 million cells,
it's more like 600k cells (2 columns per row), and it's
less than that insofar as some users may only
have 24 distinct colors among their many streams.
It's a lot of work.
This commit sets us up for the next commit, which will
save us a very expensive query.
If you are adding 15k users to a stream, and each user
has about 20 existing streams, then we need to retrieve
300k rows from the database to figure out which stream
colors they already have. We don't need all the extra
fields from Subscription, so now we get just the two
values we need for making a color map.
In the next commit we'll eliminate the other use case
for the big query, and I will explain in greater
depth how splitting out the color-picking code can
be a huge win. It is possible that some product decisions
could make this codepath easier. We could also do some
engineering specific to stream colors, such as caching
which colors users have already used.
This does cost us an extra round trip to the database.
Having the `wildcard_mentions_notify` setting turned on does
not necessarily mean that the user will receive notification
for that message. There is more nuance to this, as explained
in the updated comment.
We recently ran into a payload in production that didn't contain
an event type at all. A payload where we can't figure out the event
type is quite rare. Instead of letting these payloads run amok, we
should raise a more informative exception for such unusual payloads.
If we encounter too many of these, then we can choose to conduct a
deeper investigation on a case-by-case basis.

Given that these values are uuids, it's better to use UUIDField which is
meant for exactly that, rather than an arbitrary CharField.
This requires modifying some tests to use valid uuids.
We avoid repeating the same calculations over and
over again for the same stream.
This helps, but the real bottleneck in this function
is that send_event usually takes at least a millisecond,
and that adds up quickly if you're doing something
like subscribing 5k users to a new stream.
