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.

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().
modified_user=sub_info.user and modified_stream=sub_info.stream, added

The old name `push_notify_user_ids` was misleading, because
it does not contain user ids which should be notified for
the current message, but rather user ids who have the online
push notifications setting enabled.
When the Tornado server is restarted during an upgrade, if
server has old events with the `push_notify_user_ids` fields,
the server will throw error after this rename. Hence, we need
to explicitly handle such cases while processing the event.
We should only show the referrer name in subject of invitation emails,
and show only 'Zulip' in the 'From' header. This helps in preventing
the email from being marked as suspicious by the detection systems
when they see an employee's name as sender of an email sent from an
unrelated domain.
The behavior is already the same for reminder invitation emails where
we do not show name and only 'Zulip' in the 'From' header.
Fixes#18256.
?dl=1 causes Dropbox to send Content-Type: application/binary, which

Commit 1a7ddd9ea3 “Fix
UserActivityInterval overlap bug” introduced a mathematically
incorrect assertion about how intervals work. There’s a third way two
intervals could overlap: both the start and end of the old interval
could be inside the new interval. This probably can’t happen here
because the old interval should be at least as long as the new
interval. However, a correct overlap test can be formulated in a
simpler way anyway.

This is will make it easier to systematically use Django's
`capturOnCommitCallbacks` in tests outside of the main
`test_events` file which involve assertions on events.
Convert this function that absolutely makes a stream web public.
We already have do_change_stream_invite_only to convert
streams to public and private streams.
We also update all the fields that should be set when a stream
is made web public.
Since this is currently only useful to interpret presence data, we
send this only if presence is requested.
I'm not sure that server_timestamp is the right name for this field,
but ultimately it should match the main presence API format.
After re-assignment, mypy will still think the type of
`widget_content` to be `str`, not `Dict`. So we need to
create a new variable.
This is a prep change for stronger type checking in this
code.
This parameter has never been used, and causes an unnecessary database
query.
We keep the num_push_devices_for_user function, since we may have uses
for it down the line.
Fixes part of #14166.

Prior to this, we only supported direct mention to
the user groups. This commit extends that support
to silent mention for the user groups.
A related test case is also added.
Fixes: #11711.
Earlier, USER_GROUP_MENTIONS_RE was:
r"(?<![^\s\'\"\(,:<])@(\*[^\*]+\*)"
For the syntax: *foo*, this was unnecessarily capturing it as
*foo* and the extraction of `foo` was done using another helper
function: `extract_user_group`.
This is now changed as:
r"(?<![^\s\'\"\(,:<])@(\*(?P<match>[^\*]+)\*)"
and extraction of `foo` can be done just by using the named capture
group `match`.
This change also helps to simplify its related code path.
Earlier, MENTIONS_RE was:
r"(?<![^\s\'\"\(,:<])@(?P<silent>_?)(?P<match>\*\*[^\*]+\*\*)"
For the syntax: **foo**, this was unnecessarily capturing it as
**foo** and adding extra operation for the extraction of `foo`.
This is now changed as:
r"(?<![^\s\'\"\(,:<])@(?P<silent>_?)(\*\*(?P<match>[^\*]+)\*\*)"
and extraction of `foo` can be done just by using the named capture
group `match`.
This change also helps to simplify its related code path.
Earlier wildcard mentions were used as: @all, @everyone, @stream.
This syntax is deprecated and we will no longer support
this syntax in future. See the commits:
1. 7a4c3c1a5c
2. b650b6b38c
When we started to use these syntaxes for wildcard mentions.
Following the convention, we use uppercase for
regex. Also, `user_group_mentions` is given a
conventional name ending with `*_RE`: `USER_GROUP_MENTIONS_RE`.
These logs were pretty spammy, and there have long been much better
ways to communicate to system administrators that the incoming email
gateway is great, including, most importantly, in the section of the
emails themselves that explains how replying works.
Previously only admins were allowed to move messages between streams
and admins are allowed to post in any stream irresepctive of stream
post policy, so there was no need to check for stream post policy.
But as we now allow other members to also move messages, we need
to check whether the user who is moving the message is allowed
to post to the target stream (i.e. stream to which the messages
are being moved) and thus we allow moving messages only if the
user is allowed to post in target stream.
b7b1ec0aeb made our checks of the response
format stronger, to enforce that the json translates to a valid dict.
However, old client code (zulip_botserver) was using "" as equivalent to
response_not_required - so we need to keep backward-compatibility to not
break things built on it.
Currently, moving messages between streams is an action limited to
organization administrators. A big part of the motivation for that
restriction was to prevent users from moving messages from a private
stream without shared history as a way to access messages they should
not have access to.
Organization administrators can already just make the stream have
shared history if they want to access its messages, but allowing
non-administrators to move messages between would have
introduced a security bug without this change.
This completes the effort to make it possible to use
bulk_access_message in contexts where there are more than a handful of
messages without creating performance issues.
