This extracts a function for computing show_invites and
show_add_streams, for better readability and testability.
This commit was substantially cleaned up by tabbott.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

This experimental setting disables sending private messages in Zulip
in a crude way (i.e. users get an error when they try to send one).
It makes no effort to adjust the UI to avoid advertising the idea of
sending private messages.
Fixes#6617.
We should take adventage of the recipient field being denormalized into
the Stream model. We don't need to make queries to figure out a stream's
recipient id, so we take advantage of that to eliminate some of
those redundant queries and simplify StreamRecipientMap.
For cross realm bots, explicitly set bot_owner_id
to None. This makes it clear that the cross realm
bots have no owner, whereas before it could be
misdiagnosed as the server forgetting to set the
field.
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 change makes it possible for users to control the notification
settings for wildcard mentions as a separate control from PMs and
direct @-mentions.
Fixes#1727.
With the server down, apply migrations 0245 and 0246. 0246 will remove
the pub_date column, so it's essential that the previous migrations
ran correctly to copy data before running this.
Apparently, our change in b8a1050fc4 to
stop caching responses on API endpoints accidentally ended up
affecting uploaded files as well.
Fix this by explicitly setting a Cache-Control header in our Sendfile
responses, as well as changing our outer API caching code to only set
the never cache headers if the view function didn't explicitly specify
them itself.
This is not directly related to #13088, as that is a similar issue
with the S3 backend.
Thanks to Gert Burger for the report.
In a gigantic realm where we send several MB of `page_params`, it’s
slightly better to have the rest of the `<body>` available to the
browser earlier, so it can show the “Loading…” spinner and start
fetching subresources.

This commit adds a new setting to the user's notification settings that
will change the behaviour of the unread count in the title bar and
desktop application.
When enabled, the title bar will show the count of unread private messages
and mentions. When disabled, the title bar will act as before, showing
the total number of unread messages.
Fixes#1736.
Add new custom profile field type, External account.
External account field links user's social media
profile with account. e.g. GitHub, Twitter, etc.
Fixes part of #12302
Namely, here we add the "plan_includes_wide_organization_logo" and
"upgrade_text_for_wide_organization_logo" to the page_params (which
is set in zerver/lib/events.py).
"plan_includes_wide_organization_logo" is True if the plan is not of
the Realm.LIMITED type. We need to add this extra boolean parameter
instead of just using "realm_plan_type" to make things a lot easier
to work with on the frontend side, especially considering that
handlebars won't allow checking for equality in its {{#if}} blocks.
Rename notification property `enable_stream_sounds` to
`enable_stream_audible_notifications` to match with other
notification property patterns.
Fixes part of #12304
This adds a setting to control Zulip's default behavior of sorting to
bottom and graying out inactive streams. The previous logic is still
the default "automatic", but this gives users more control. See the
models.py comment for details.
Fixes#11524.
This commit replaces the `create_stream_by_admins_only` setting with a
new `create_stream_policy` setting, which mirroring the structure of
the existing `invite_to_stream_policy`.
This is important preparation for migrating the waiting period feature
to be its own independent setting.
Fixes#12236.
Fixes#12251.
Previously when disabling name changes in server settings, instead
of realm settings, the name edit button did not get disabled.
Changing name resulted in a message stating `no changes made`.
Fixes#12132.
Realm setting to disable avatar changes is already present.
The `AVATAR_CHANGES_DISABLED` setting now follows the same
2-setting model as `NAME_CHANGES_DISABLED`.
This is useful when syncing avatars from an integrated LDAP/active
directory.
The upload avatar and delete avatar buttons are hidden if avatar
changes are disabled and the user is a non-admin.
If the user has a gravatar set, then the user will not be able to
upload an image as their avatar if avatar changes are disabled.
Part of #12132.
This commit creates a new organization setting that determines whether
a user can invite other users to streams. Previously this was linked
to the waiting period threshold, but this was both not documented and
overly limiting.
With significant tweaks by tabbott to change the database model to not
involve two threshhold fields, edit the tests, etc.
This requires follow-up work to make the create stream policy setting
work how this code implies it should.
Fixes#12042.
This adds experimental support in /register for sending key
statistical data on the last 1000 private messages that the user is a
participant in. Because it's experimental, we require developers to
request it explicitly in production (we don't use these data yet in
the webapp, and it likely carries some perf cost).
We expect this to be extremely helpful in initializing the mobile app
user experience for showing recent private message conversations.
See the code comments, but this has been heavily optimized to be very
efficient and do all the filtering work at the database layer so that
we minimize network transit with the database.
Fixes#11944.
Previously, we had some expensive-to-calculate keys in
zulip_default_context, especially around enabled authentication
backends, which in total were a significant contributor to the
performance of various logged-out pages. Now, these keys are only
computed for the login/registration pages where they are needed.
This is a moderate performance optimization for the loading time of
many logged-out pages.
Closes#11929.
The night logo synchronization on the settings page was perfect, but
the actual display logic had a few problems:
* We were including the realm_logo in context_processors, even though
it is only used in home.py.
* We used different variable names for the templating in navbar.html
than anywhere else the codebase.
* The behavior that the night logo would default to the day logo if
only one was uploaded was not correctly implemented for the navbar
position, either in the synchronization for updates code or the
logic in the navbar.html templates.
Add all the stop words to page_params, reading from the
`zulip_english.stop` database, with caching to avoid loading the file
on every page load.
Part of #10592.
This adds a setting under "Notification" section of
"Organization settings" tab, which enables Organization administrator to
control whether the missed message emails include the message content or
not.
Fixes: #11123.
You can now pass in an info field with a value
like "out to lunch" to the /users/me/status,
and the server will include that in its outbound
events.
The semantics here are that both "away" and
"status_text" have to have defined values in order
to cause changes. You can omit the keys or
pass in None when values don't change.
The way you clear info is to pass the empty
string.
We also change page_params to have a dictionary
called "user_status" instead of a set of user
ids. This requires a few small changes on the
frontend. (We will add "status_text" support in
subsequent commits; the changes here just keep
the "away" feature working correctly.)
This adds a new realm_logo field, which is a horizontal-format logo to
be displayed in the top-left corner of the webapp, and any other
places where we might want a wide-format branding of the organization.
Tweaked significantly by tabbott to rebase, fix styling, etc.
Fixing the styling of this feature's loading indicator caused me to
notice the loading indicator for the realm_icon feature was also ugly,
so I fixed that too.
Fixes#7995.
This form isn't actively used, which is how it ended up broken, but it
basically didn't display its content properly at all.
Convert it to use our standard white-box framework.
This still doesn't look great in various ways, but it's at least not
obviously totally busted now.
Also, add a new notification sound, "ding". It comes from
https://freesound.org, where the original Zulip notification sound comes
from as well. In the future, new sounds can be added by adding audio
files to the `static/audio/notification_sounds` directory.
Tweaked significantly by tabbott:
* Avoided removing static/audio/zulip.ogg, because that file is
checked for by old versions of the desktop app.
* Added a views check for the sound being valid + tests.
* Added additional tests.
* Restructured the test_events test to be cleaner.
* Removed check_bool_or_string.
* Increased max length of notification_sound.
* Provide available_notification_sounds in events data set if global
notifications settings are requested.
Fixes#8051.
This is preparatory work for settings controlling who can see user
emails; it includes the API-level support for editing it, but no code

This adds a feature in the "Notification" section of "Settings" tab,
which lets user enable or disable login emails notification.
Tweaked by tabbott to simplify the test.
Fixes: #5795, progress towards #5854.
If `TEXT_EMOJISET` is currently selected emojiset then fallback to
`GOOGLE_EMOJISET` for displaying emojis in emoji picker and
composebox typeahead. We should pre-load the spritesheets in`emoji.js`
even in case of text emojiset otherwise on slow networks emoji picker
will appear empty initially.
Fixes#10124.
Users in the waiting period category cannot subscribe other users to
a stream. When a user tries to mention another unsubscribed user, a
warning message appears with a subscribe button on it to subscribe
the other user.
This commit removes the subscribe button and changes the warning text
for users in the waiting period category.
This ensures that the format of this data structures matches that for
in-realm bots in the main users data structure (including avatars,
etc.).
Fixes#10138.

This setting isn't intended to exist long term, but instead to make it
possible to merge our search pills code before we're ready to cut over
production environments to use it.
This commit moves all files previously under the 'app' bundle in
the Django pipeline to being compiled by webpack under the 'app'
entry point. In the process, it moves assets under the app entry
to a file called app.js that consumes all relevant css and js files.
This commit also edits the webpack config to be able to expose certain
variables for third party libraries that are currently required by
some modules. This is bad coding form and should be refactored to
requiring whatever dependencies a module may have; we're just
deferring that to the future to simplify the series of transitions we
need to do here. The variable exposure is done using expose-loader in
webpack.
The app/index.html template is edited to override the newly introduced
'commonjs' block in the base template. This is done as a temporary
measure so as not to disrupt other pages on the app during the transition.
It also fixes the value of the 'this' context that was being inferred
as window by third party libraries. This is done using imports-loader
in the webpack config. This is also messy and probably isn't how we
want things to work long term.
The only changes visible at the AST level, checked using
https://github.com/asottile/astpretty, are
zerver/lib/test_fixtures.py:
'\x1b\\[(1|0)m' ↦ '\\x1b\\[(1|0)m'
'\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n'
which is fine because re treats '\\x1b' and '\\n' the same way as
'\x1b' and '\n'.

We now have a simple algorithm: First, look at the URL path
(e.g. /de/, which is intended to be an override). Second, look at the
language the user has specified in their settings.
This should make it easier for us to iterate on a less-dense Zulip.
We create two classes on body, less_dense_mode and more_dense_mode, so
that it's easy as we refactor to separate the two concepts from things
like colors that are independent.
This is primarily useful for the mobile app, but could also be used to
control whether we display push-notifications related settings to
users in the web UI.
We only use this data in a rarely-used settings screen, and it can be
large after years of posting screenshots.
So optimize the performance of / by just loading these data when we
actually visit the page.
This saves about 300ms of runtime for loading the home view for my
user account on chat.zulip.org.
This eliminates the need to call user_ids_to_users inside the
get_service_dicts_for_bots code path, saving a database query.
This completes my refactor to fix backend performance issues in this
code path. Previously, our messy layering of queries that resulted in
Zulip doing work even if none of the bots actually had Services or
config_data.
This commit changes the tests based on the fact that pygments.css
will no longer be found in the template during testing. pygemnts.css
is being compiled by webpack under app-styles and so we look for the
stubentry for app-styles instead.
Tweaked by tabbott to do a cleaner test.
The handlebars error message is just for the manual development
environment; this prevents the state of compiling handlebars templates
from run-dev.py from potentially causing the unit tests to fail.
Add realm setting to set time limit for message deleitng.
Set default value of message_content_delete_limit_seconds
to 600 seconds(10 min).
Thanks to Shubham Dhama for rebasing and reworking this. Some final

Fixes#7344.
Implement few optimizations for reading admin's bot dicts from database
for a constants number of requests:
- add models.get_user_profiles_by_ids() for reading bots profiles
by single query from database
- add models.get_services_for_bots() for reading services for bots
by single query from database
- add bot_config.get_bot_configs() for reading config data for bots
by single query from database
Fixes#8838
This bot was basically a duplicate of NOTIFICATION_BOT for some
specific corner cases, and didn't add much value. It's better to just
eliminate it, which also removes some ugly corner cases around what
happens if the user account doesn't exist.
This number is way too high, because of a recent regression. Adding a
test here lets us prevent similar regressions in the future and
provides an easy way to be sure if we've fixed the issue.
