The headings for return values were currently hardcoded
in cases where they occur, but they can be rendered directly
in the markdown extension if the return values exist.
This causes avatars and emoji which are hosted by Zulip in S3 (or
compatible) servers to no longer go through camo. Routing these
requests through camo does not add any privacy benefit (as the request
logs there go to the Zulip admins regardless), and may break emoji
imported from Slack before 1bf385e35f,
which have `application/octet-stream` as their stored Content-Type.
Earlier, the notification-blocking for messages from muted senders
was a side-effect of we never sending notifications for messages
with the "read" flag.
This commit decouples these two things, as a prep for having new
settings which will allow users to **always** receive email
notifications, including when/if they read the message during the
time the notifications is in the queue.
We still mark muted-sender messages as "read" when they are sent,
because that's desirable anyways.
Fixes#17277.
The main limitation of this implementation is that the sync happens if
the user authing already exists. This means that a new user going
through the sign up flow will not have their custom fields synced upon
finishing it. The fields will get synced on their consecutive log in via
SAML in the future. This can be addressed in the future by moving the
syncing code further down the codepaths to login_or_register_remote_user
and plumbing the data through to the user creation process.
We detail that limitation in the documentation.
The old type in default_settings wasn't right - limit_to_subdomains is a
List[str]. We define a TypeDict for capturing the typing of the settings
dict more correctly and to allow future addition of configurable
attributes of other non-str types.
This is a prep change for importing (and using) `dataclasses.field`
elsewhere in the same file, because pyflakes would throw "Import
module shodowed" errors otherwise.
Rename poll_timeout to event_queue_longpoll_timeout_seconds
and change its value from 90000 ms to 90 sec. Expose its
value in register api response when realm data is fetched.
Bump API_FEATURE_LEVEL to 74.
Expose the boolean value server_needs_upgrade in the
responses for register api so that it can be used
by mobile and terminal clients as well.
Highlighted in api changelog as part of
feature level 74 in commit fb93c96
(next commit).
Shift functions used for compatibility from
zerver.lib.home (is_outdated_server) and
zerver.view.compatibility (pop_numerals,
version_lt, find_mobile_os,
is_outdated_desktop_app, is_unsupported_browser)
to zerver.lib.compatibility module.
This locks the message row while a reaction is being added/removed,
which will handle race conditions caused by deleting the message
at the same time.
We make sure that events work happens outside the transaction,
so that in case there's some problem with the queue processor, the
locks aren't held for too long.
As a nice side-effect, we also handle race conditions from double
adding reactions, because once the message is locked, a duplicate
request will wait till the earlier transaction commits, and hence
will not throw `IntegrityErrors`s (rather, will be handled in our
safety check in the /views code itself), which earlier had to be
handled explicitly.
This locks the message while creating a submessage, which
will handle race conditions caused by deleting the message
simultaneously.
We make sure that events work happens outside the transaction,
so that in case there's a problem with the queue processor,
the locks aren't held for too long.
Further commits will start locking the message rows while
adding related fields like reactions or submessages,
to handle races caused by deleting the message itself at the
same time.
The message locking implemented then will create a possibility
of deadlocks, where the related field transaction holds a lock
on the message row, and the message-delete transaction holds a
lock on the database row of the related field (which will also
need to be deleted when the message is deleted), and both
transactions wait for each other.
To prevent such a deadlock, we lock the message itself while
it is being deleted, so that the message-delete transaction
will have to wait till the other transaction (which is about
to delete the related field, and also holds a lock on the
message row) commits.
https://chat.zulip.org/#narrow/near/1185943 has more details.
Further commits will hook `send_event` calls to `on_commit`
in some cases. This change will make it easier to test such
situations.
We don't need to actually capture the callbacks, because the
events sent are already tested via the list in which they are
captured by `tornado_redirected_to_list`.
This commit fixes a bug where moving messages between streams was
not allowed for non-admins when allow_community_topic_editing was
set to false and move_messages_between_streams_policy was set to
Realm.POLICY_MEMBERS_ONLY.
The bug is fixed by calling can_edit_content_or_topic only when
topic or content edit is there and not in the case where only
message is moved from one stream to another.
This commit extracts the logic of checking the message edit permissions,
like whether the sender is same as user, whether it is a (no topic)
message or whether community topic editing is allowed, into a separate
function.
This is a prep commit for fixing a bug where permission to move messages
between streams is affected by permission of editing topics.
Previously when enforcing the check to do not allow editing topics
after a certain time, we were checking whether 'content is None' and
considering it as that if content is None then there must be topic
edit.
But after adding support for moving messages between streams it can be
the case that we are neither changing topic nor content and just moving
streams, and the original code raises error if this is done after the
time limit of editing topics, which is wrong.
This commit fixes this by actually checking 'topic_name is not None'.
This should help with #17425, where messages with lots of LaTeX are
lost, due to the large expansion factor.
This isn't a total fix for this - large messages with lots of LaTeX
can still end up larger than 1MB, and rendering could timeout, but
this fix should help significantly.
1MB is still small enough that I don't expect we'll run into any DOS
problems - my testing didn't show any problems rendering messages that
contain ~1MB of LaTeX.
This will offer users who are self-hosting to adjust
this value. Moreover, this will help to reduce the
overall time taken to test `test_markdown.py` (since
this can be now overridden with `override_settings`
Django decorator).
This is done as a prep commit for #18641.
Checked the email looked OK in `/emails` for both creating realm and
registering within an existing one.
Not sure zerver/tests/test_i18n.py test has been suppressed correctly.
Fixes#17786.
d66cbd2832 added these mentioning
"always_notify" for some reason, but always_notify clearly isn't a real
thing in this context so the comments need to be fixed to eliminate this
potential source of confusion.
Our current logic only allows S3 block storage providers whose
upload URL matches with the format used by AWS. This also allows
other styles such as the "virtual host" format used by Oracle cloud.
Fixes#17762.
These checks are more related to the API than the editability
or permissions logic, so it makes sense to handle them first
before further processing the request.
Also split the main test class to separate out the tests for
this logic.
This also simplifies some tests by reducing the data setup
required to reach failure.
Tweaked by tabbott to avoid losing the topic_name.strip().
