The flow in recipient_for_user_profiles previously worked by doing
validation on UserProfile objects (returning a list of IDs), and then
using that data to look up the appropriate Recipient objects.
For the case of sending a private message to another user, the new
UserProfile.recipient column lets us avoid the query to the Recipient
table if we move the step of reducing down to user IDs to only occur
in the Huddle code path.
Previously, if the user had interacted with the Zulip mobile app in
the last ~140 seconds, it's likely the mobile app had sent presence
data to the Zulip server, which in turns means that the Zulip server
might not send that user mobile push notifications (or email
notifications) about new messages for the next few minutes.
The email notifications behavior is potentially desirable, but the
push notifications behavior is definitely not -- a private message
reply to something you sent 2 minutes ago is definitely something you
want a push notification for.
This commit partially addresses that issue, by ignoring presence data
from the ZulipMobile client when determining whether the user is
currently engaging with a Zulip client (essentially, we're only
considering desktop activity as something that predicts the user is
likely to see a desktop notification or is otherwise "online").
This removes the last of the messy use of regular expressions outside
bugdown to make decisions on whether a message contains an attachment
or not. Centralizing questions about links to be decided entirely
within bugdown (rather than doing ad-hoc secondary parsing elsewhere)
makes the system cleaner and more robust.
This commit wraps up the work to remove basic regex based parsing
of messages to handle attachment claiming/unclaiming. We now use
the more dependable Bugdown processor to find potential links and
only operate upon those links instead of parsing the full message
content again.
Previously, we would naively set has_attachment just by searching
the whole messages for strings like `/user_uploads/...`. We now
prevent running do_claim_attachments for messages that obviously
do not have an attachment in them that we previously ran.
For example: attachments in codeblocks or
attachments that otherwise do not match our link syntax.
The new implementation runs that check on only the urls that
bugdown determines should be rendered. We also refactor some
Attachment tests in test_messages to test this change.
The new method is:
1. Create a list of potential_attachment_urls in Bugdown while rendering.
2. Loop over this list in do_claim_attachments for the actual claiming.
For saving:
3. If we claimed an attachment, set message.has_attachment to True.
For updating:
3. If claimed_attachment != message.has_attachment: update has_attachment.
We do not modify the logic for 'unclaiming' attachments when editing.
The streams:all adveritsement notice in search should only appear
after we've already received the response from the server, to avoid a
mix of problems ranging from misplaced loading indicator to scrolling
issues to the notice just being distracting while you're waiting for
the server to return results.
We need to add a pre_scroll_cont parameter to the message_fetch API,
since adding this notice would otherwise potentially throw off the
scroll positioning logic for which message to select.
Fixes#13441.
In 452e226ea2 and
648a60baf6, we changed how `search:`
narrows work to:
(1) Never mark messages as read inside searches (search:)
(2) Take you to the bottom, not the first unread, if a `near:` or
similar wasn't specified.
This is far better behavior for these use cases, because in these
narrows, you can't actually see all the context around the target
messages, so marking them as read is counterproductive. This is
especially important in `has:mention` where you goal is likely
specifically to keep track of which threads mentioning you haven't
been read. But in many other narrows, the current behavior is
effectively (1) setting the read bit on random messages and (2) if the
search term matches many messages in a muted stream with 1000s of
unreads, making it hard or impossible to find recent search matches.
The new behavior is that any narrow that is structurally a search of
history (including everything that that isn't a stream, topic,
pm-with, "all messages" or "private messages") gets that new behavior
of being unable to mark messages as read and narrows taking you to the
latest matching messages.
A few corner cases of interest:
* `is:private` is keeping the old behavior, because users on
chat.zulip.org found it confusing for `is:private` to not mark
messages as read when one could see them all. Possibly a more
complex answer is required here.
* `near:` narrows are getting the new behavior, even if it's a stream:
+ topic: narrow. This is debatable, but is probably better than
what was happening before.
Modified significantly by tabbott for cleanliness of implementation,
this commit message, and unit tests.
Fixes#9893. Follow-up to #12556.
add_a, add_oembed_data and add_embed are only called by
InlineInterestingLinksProcessor and this commit allows
these methods to access self.markdown object.
In 1fe4f795af, we added the
wildcard_mentions_notify setting, which controls whether wildcard
mentions should be treated as mentions for the purposes of
notifications. The original implementation focused on the more
important area of email/push notifications, and neglected to address
desktop notifications for wildcard mentions.
This change makes the wildcard_mentions_notify flag behave correctly
for desktop/sound notifications, including unit tests.
Fixes#13073.
We register ZulipRemoteUserBackend as an external_authentication_method
to make it show up in the corresponding field in the /server_settings
endpoint.
This also allows rendering its login button together with
Google/Github/etc. leading to us being able to get rid of some of the
code that was handling it as a special case - the js code for plumbing
the "next" value and the special {% if only_sso %} block in login.html.
An additional consequence of the login.html change is that now the
backend will have it button rendered even if it isn't the only backend
enabled on the server.
This commit builds a more complete concept of an "external
authentication method". Our social backends become a special case of an
external authentication method - but these changes don't change the
actual behavior of social backends, they allow having other backends
(that come from python-social-auth and don't use the social backend
pipeline) share useful code that so far only serviced social backends.
Most importantly, this allows having other backends show up in the
external_authentication_methods field of the /server_settings endpoint,
as well as rendering buttons through the same mechanism as we already
did for social backends.
This moves the creation of dictonaries describing the backend for the
API and button rendering code away into a method, that each backend in
this category is responsible for defining.
To register a backend as an external_authentication_method, it should
subclass ExternalAuthMethod and define its dict_representation
classmethod, and finally use the external_auth_method class decorator to
get added to the EXTERNAL_AUTH_METHODS list.
The previous documentation was essentially wrong, in that it
recommended copying certain settings that would cause significant
problems post-import if they were indeed copied.
This commit has a side-effect that we also now allow mixed lists,
but they have different syntax from the commonmark implementation
and our marked output. For example, without the closing li tags:
Input Bugdown Marked
-------------------------------------
<ul>
- Hello <li>Hello <ul><li>Hello</ul>
+ World <li>World <ul><li>World
+ Again <li>Again <li>Again</ul>
* And <li>And <ul><li>And
* Again <li>Again <li>Again</ul>
</ul>
The bugdown render is in line with what a user in #13447 requests.
Fixes#13477.
Adds required API and front-end changes to modify and read the
wildcard_mentions_notify field in the Subscription model.
It includes front-end code to add the setting to the user's "manage
streams" page. This setting will be greyed out when a stream is muted.
The PR also includes back-end code to add the setting the initial state of
a subscription.
New automated tests were added for the API, events system and front-end.
In manual testing, we checked that modifying the setting in the front end
persisted the change in the Subscription model. We noticed the notifications
were not behaving exactly as expected in manual testing; see
https://github.com/zulip/zulip/issues/13073#issuecomment-560263081 .
Tweaked by tabbott to fix real-time synchronization issues.
Fixes: #13429.
Previously, get_recent_private_messages could take 100ms-1s to run,
contributing a substantial portion of the total runtime of `/`.
We fix this by taking advantage of the recent denormalization of
personal_recipient into the UserProfile model, allowing us to avoid
the complex join with Recipient that was previously required.
The change that requires additional commentary is the change to the
main, big SQL query:
1. We eliminate UserMessage table from the query, because the condition
m.recipient_id=%(my_recipient_id)d
implies m is a personal message to the user being processed - so joining
with usermessage to check for user_profile_id and flags&2048 (which
checks the message is private) is redundant.
2. We only need to join the Message table with UserProfile
(on sender_id) and get the sender's personal_recipient_id from their
UserProfile row.
Fixes#13437.
This is adds foreign keys to the corresponding Recipient object in the
UserProfile on Stream tables, a denormalization intended to improve
performance as this is a common query.
In the migration for setting the field correctly for existing users,
we do a direct SQL query (because Django 1.11 doesn't provide any good
method for doing it properly in bulk using the ORM.).
A consequence of this change to the model is that a bit of code needs
to be added to the functions responsible for creating new users (to
set the field after the Recipient object gets created). Fortunately,
there's only a few code paths for doing that.
Also an adjustment is needed in the import system - this introduces a
circular relation between Recipient and UserProfile. The field cannot be
set until the Recipient objects have been created, but UserProfiles need
to be created before their corresponding Recipients. We deal with this
by first importing UserProfiles same way as before, but we leave the
personal_recipient field uninitialized. After creating the Recipient
objects, we call a function to set the field for all the imported users
in bulk.
A similar change is made for managing Stream objects.
Fixes#13452.
The migration from UserProfile.is_realm_admin/UserProfile.is_guest in
e10361a832 broke our LDAP-based support
for setting a user's role via LDAP properties, which relied on setting
those fields. Because the django-auth-ldap feature powering that only
supports booleans (and in any case, we don't want to expose constants
like `ROLE_REALM_ADMINISTRATOR` to the LDAP configuration interface),
it makes sense to provide setters for these legacy fields for
backwards-compatibility.
We lint against using these setters directly in Zulip's codebase
directly. The issue with using these is that when changing user's
.role we want to create appropriate RealmAuditLog entries and send
events. This isn't possible when using these setters - the log entries
and events should be created if the role change in the UserProfile is
actually save()-ed to the database - and on the level of the setter
function, it's not known whether the change will indeed be saved.
It would have to be somehow figured out on the level of post_save
signal handlers, but it doesn't seem like a good design to have such
complexity there, for the sake of setters that generally shouldn't be
used anyway - because we prefer the do_change_is_* functions.
The purpose of this change is narrowly to handle use cases like the
setattr on these boolean properties.
