Previously, we could 500 if an organization administrator scanned
possible PreregistrationUser IDs looking for a valid invitation they
can interact with.
They couldn't do anything, so no security issue, but this fixes that
case to just be a 400 error as it should be.
These functions don't really belong in actions.py, so we move them out,
into email_mirror_helpers.py. They can't go directly into
email_mirror.py or we'd get circular imports resulting in ImportError.
There were several problems with the old format:
* The sender was not necessarily the sender; it was the person who did
the deletion (which could be an organization administrator)
* It didn't include the ID of the sender, just the email address.
* It didn't include the recipient ID, instead having a semi-malformed
recipient_type_id under the weird name recipient_user_ids.
Since nothing was relying on the old behavior, we can just fix the
event structure.
Fixes#9840.
Old addresses caused bugs in some cases with non-latin characters in
stream names (see issue number above). We switch to using django's
slugify helper function to convert stream names to full ascii, while
also getting rid of problematic non-alphanumeric characters, in a
reasonable way. See Django's documentation for slugify to see more about
how this function works.
Tests extended by tabbott to cover cases where we do end up with ascii.
To prepare for changing how the stream name gets encoded into mirror
email addresses while making sure old addresses keep working, we ignore
the stream_name part when receiving emails into the mirror and we only
look at the email_token to identify into which stream to mirror the
email.
Follow up on 92dc363. This modifies the ScheduledEmail model
and send_future_email to properly support multiple recipients.
Tweaked by tabbott to add some useful explanatory comments and fix
issues with the migration.
This field is primarily intended to support avoiding displaying the
"more topics" feature in new organizations and streams, where we might
know that all messages in the stream are already available in the
browser.
Based on original work by Roman Godov, and significantly modified by
tabbott.
The second migration involved here could be expensive on Zulip Cloud,
but is unlikely to be an issue on other servers.
When a Zephyr user deactivates their account, they should be
automatically turned into a mirror dummy user (so that other users can
continue to interact with them as normal for a Zephyr user who isn't
using Zulip).
Fixes part 3 of #10612. When sending an email to the email mirror to a
stream address, if "+show-sender" is added in the address, the stream
message will now include "From: <sender>" at the top.
In commit de65a04 we can see that if the need ever arises to modify
how stream descriptions are rendered, we would need to make changes
at 5 different call points which can be quite cumbersome. So this
functionality has been extracted to a new method called
'render_stream_descriptions'.
This commit leverages the ahocorasick algorithm to build a set of user_ids
that have their alert_words present in the message. It runs in linear time
of the order of length of the input message as opposed to number of
alert_words. This is after building a ahocorasick Automaton which runs
in O(number of alert_words in entire realm) which is usually cached.
This is important for situations such as with our Zapier app,
where the requesting user may be a bot that would like to access
its owner's subscriptions.
Tweaked by tabbott to eliminate the 2^N growth of cases in
do_get_streams.
We want to use the baseline features of bugdown, but not fancy things
like inline URL previews, since the whole structure of stream
descriptions is to have a single-line thing supporting some
formatting.
The migration part of this change fixes a bug encountered by some
organizations upgrading from older versions of Zulip.
This allows us to have some features using bugdown rendering where
inline image previews will not be rendered (which would be problematic
for e.g. stream descriptions).
Guest users will just get an empty list of default streams; we also
hide the "Default streams" organization view from the guest users UI.
This is for consistency with not providing guest users the full list
of streams in an organization.
Fixing this involves fixing the backend to handle unchanged field
submissions of the Zoom credentials without trying to re-validate the
credentials (for performance) as well as to fetch the already-sent
secret.
When a bunch of messages with active notifications are all read at
once -- e.g. by the user choosing to mark all messages, or all in a
stream, as read, or just scrolling quickly through a PM conversation
-- there can be a large batch of this information to convey. Doing it
in a single GCM/FCM message is better for server congestion, and for
the device's battery.
The corresponding client-side logic is in zulip/zulip-mobile#3343 .
Existing clients today only understand one message ID at a time; so
accommodate them by sending individual GCM/FCM messages up to an
arbitrary threshold, with the rest only as a batch.
Also add an explicit test for this logic. The existing tests
that happen to cause this function to run don't exercise the
last condition, so without a new test `--coverage` complains.
ACCOUNT_ACTIVATION_DAYS doesn't seems to be used anywhere.
INVITATION_LINK_VALIDITY_DAYS seems to do it's job currently.
(It was only ever used in very early Zulip commits).
For internal stream messages, most of the time, we have access to
a Stream object. For the few corner cases where we don't, it is a
much cleaner approach to have a separate function that accepts a
stream name than having one multi-option helper that accepts both
names and objects.
If the caller has access to a Stream object, it is wasteful to
query a database for a stream by ID or name. In addition, not
having to go through stream names eliminates various classes of
possible bugs involved with re-fetching the Stream object by name.
If the caller has access to a Stream object, it is wasteful to
query a database for a stream by ID or name. In addition, not
having to go through stream names eliminates various classes of
possible bugs involved with getting a Stream object back.
The name for_stream_name is more appropriate here. The name
for_stream is more suitable for a function that takes in a Stream
object, which we're about to add.
Our hash-naming of production assets interacted badly with the "look
at files in a directory" algorithm used to determine what sound
options exist for the "notification sound" feature. For lack of a
better solution, we fix this by excluding files with an extra `.` in
their name.
This causes changing the email_address_visibility field to actually
modify what user_profile.email values are generated for users, both on
user creation and afterwards as email addresses are edited.
The overall feature isn't yet complete, but this brings us pretty close.
This commit does the following three things:
1. Update stream model to accomodate rendered description.
2. Render and save the stream rendered description on update.
3. Render and save stream descriptions on creation.
Further, the stream's rendered description is also sent whenever the
stream's description is being sent.
This is preparatory work for eliminating the use of the
non-authoritative marked.js markdown parser for stream descriptions.
Ever since we implemented support for stream IDs in Addressee,
Addressee.stream_name() can now return None. This commit ensures
that _internal_prep_message only calls ensure_stream when
Addressee.stream_name() is not None.
This commit also contains the following auxiliary changes:
* Adds a custom exception, StreamWithIDDoesNotExist for when
a stream with a given ID does not exist because the error
message returned by StreamDoesNotExist only makes with stream
names, not IDs.
* Adds a new helper, get_stream_by_id_in_realm, which is similar
to get_user_profile_by_id_in_realm (introduced in #10391).
* Adds a helper, validate_stream_id_with_pm_notification, which
returns the Stream object associated with a given ID and also
handles PM notifications to the bot owner if the message was
sent by a bot and if the stream does not exist or has no
subscribers.
* Modifies the message sent by send_pm_if_empty_stream to
accommodate stream IDs.
Note that all of the above changes are required before check_message
can be modified to support stream IDs.
