Extracting the function makes it a bit easier to
test and use in a generic way.
Also, I wanted this to live in stream_data, so that
it's easier to find if we change how we model
subscriber data.
Finally, I use _.every to do the subset check
instead of `_.difference`, since _.difference
is actually N-squared:
_.difference = restArguments(function(array, rest) {
rest = flatten(rest, true, true);
return _.filter(array, function(value){
return !_.contains(rest, value);
});
});
And we don't actually want to build a list only
to check that it's zero vs. nonzero length.
We now do this, which short circuits as soon
as it finds any key that is only in sub1:
return _.every(sub1.subscribers.keys(), (key) => {
return sub2_set.has(key);
});
We have ~5 years of proof that we'll probably never
extend Dict with more options.
Breaking the classes into makes both a little faster
(no options to check), and we remove some options
in FoldDict that are never used (from/from_array).
A possible next step is to fine-tune the Dict to use
Map internally.
Note that the TypeScript types for FoldDict are now
more specific (requiring string keys). Of course,
this isn't really enforced until we convert other
modules to TS.
This should make any operation on subscribed
streams faster (we won't need to filter out
unsubscribed streams every time).
I started writing this before I realized we
had a bug where we call `subscribed_streams`
in a nested loop.
After fixing the bugs, this is not as much of
a bottleneck, but it's still a speedup in many
important places:
* build left sidebar
* every keystroke in search bar
* first keystroke in making #stream_links
* every keystroke in compose stream box
The streams settings code is kinda complicated.
It does a non-deterministic sort of the "others"
bucket when you add elements to the left panel.
They get hidden, anyway. Our values() call now
puts subscribed streams first. It never guaranteed
order, but putting subscribed streams first is
probably a good behavior for most situations.
This defers O(N*S) operations, where
N = number of streams
S = number of subscribers per stream
In many cases we never do an O(N) operation on
a stream. Exceptions include:
- checking stream links from the compose box
- editing a stream
- adding members to a newly added stream
An operation that used to be O(N)--computing
the number of subscribers--is now O(1), and we
don't even pay O(N) on a one-time basis to
compute it (not counting the cost to build the
array from JSON, but we have to do that).
Calling `set_filter_out_inactives` is expensive, since we
count up the number of subscribed streams, which iterates
through all your streams, creates a new list of subscribed
streams, then counts them.
In my dev setup, I created 700 streams, and this shaved
about 700ms off of the initial call to `build_stream_list`.
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 .

This commit was originally automatically generated using `tools/lint
--only=eslint --fix`. It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

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 migrates the Subscription's notification fields from a
BooleanField to a NullBooleanField where a value of None means to
inherit the value from user's profile.
Also includes a migrations to set the corresponding settings to None
if they match the user profile's values. This migration helps us in
getting rid of the weird "Apply to all" widget that we offered on
subscription settings page.
The mobile apps can't handle None appearing as the stream-level
notification settings, so for backwards-compatibility we arrange to
only send True/False to the mobile apps by applying those defaults
server-side. We introduce a notification_settings_null value within a
client_capabilities structure that newer versions of the mobile apps
can use to request the new model.
This mobile compatibility code is pretty effectively tested by the
existing test_events tests for the subscriptions subsystem.
This makes the "more topics" option which appears below the list of
known topics in the left sidebar appear only when it's possible there
are actually more topics to be displayed. Two specific cases it
resolves completely include:
* Newly created realms; this widget was a common source of confusion
for new organization administrators.
* Newly created streams.
There are still some corner cases this doesn't handle, e.g. if you
just joined a private stream with protected history, but there isn't
as easy a fix for those.
Essentially rewritten by tabbott to fix code duplication and comment
extensively.
Fixes#10265.
Use the results of commit #73d26c8 to remove the method
`render_stream_description` in static/js/stream_data.js and instead
use the rendered_description attribute now being sent by the backend.
This will be a valuable optimization and a step towards removing the
need for the marked.js markdown parser and speeding up the client end.
This function unlike `invite_streams()` returns an array of objects having
various info (name, stream_id, invite_only, default_stream) related to
streams rather than an array of names of streams.
Add explanation in popover on disabled add-subscriptions input elements,
admin can't add subscribers to non subscribed private streams, only
subscribed users can.
Fixes#10593
This function used to be called initialize_from_page_params(),
and we called it indirectly through `subs.js`.
Now we call it directly from `ui_init.js`, which gives us a
bit more control over how things are initialized. In fact,
this sets us up for the next commit, where I fix a recent
regression I introduced.
The stream_list test that was fixed here was sort of
broken. It accomplished the main goal of verifying
what gets rendered, but now the data setup part is
more like the actual app code (and simpler, too).
This is definitely a micro-optimization, but avoiding
creating an extra object speeds up page loads by about
20ms per 1000 streams.
It's slightly sketchy to mutate the value in place, but
the original value never gets used again.
We now let color_data keep its own state for
unused_colors, so that we longer have to pass in
a large list of unused_colors every time we want
to assign a new stream color.
This mostly matters at startup, where we might
be cycling through 5000 streams. We claim all
the unused colors up front.
Each operation now has an upper bound of expensiveness,
where the worst case scenario is basically popping
off the first element of a list of <= 24 colors.
The algorithm is now deterministic, too, to make
it easier to test. It's unclear whether random color
assignment ever had much benefit, and it made unit
testing the algorithm difficult. Now we have 100%
line coverage.
Fixes part of #10902.
Guest users can't access subscribers of any(public or private)
non-subscribed streams. Therefore, hide subscribers list
of all non-subscribed streams from guest users in UI.
Fixes#10749 (the previous parts were fixed already).
Guest users can't subscribe themselves to any stream, so we hide the
"Subscribe" button. Previously, it was showing Subscribe button after
a guest user unsubscribed from a stream.
Fixes part of #10749.
Admin users can't add private unsubscribed streams to the default
streams list. Therefore, we shouldn't include private streams the
user is not subscribed to in the default stream suggestions.
We move remove_deactivated_user_from_all_streams
into stream_events.js. There were some minor changes
to rename variables and also to not rely on using
`stream_info`.
This allows several modules to no longer need
to import `narrow` (or, in our current pre-import
world, to not have to use that global).
The broken dependencies are reflected in the node
tests, which should now run slightly faster.
We don't need to get sorted streams in the "source"
function for typeahead, since we sort them later,
and we don't need to recalculate values.
This preserves the behavior that we include
unsubscribed streams in the typeahead, which is
probably intentional.
We move some data code from subs.js to stream_data.js.
It's not clear we have been using the optimal sort for
dealing with locales, but this change preserves the
current behavior. The only subtle change here is that
we look up subs using a Dict now instead of a plain
JS object.
Previous commits have fully implemented the logic for stream email
notifications; this final commit adds support for configuring it to
the UI.
Fixes#6511.
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
Now that we've moved it into a bulleted set of options inside a modal,
there's no good reason to have separate variables for the corner cases
around who can manage a stream.
Partially fixes#4708.
Implements a first version (v1) for the feature. The next step would be
to allow admins to toggle `is_announcement_only` in the UI.
This is preparation for enabling an eslint indentation configuration.
90% of these changes are just fixes for indentation errors that have
snuck into the codebase over the years; the others are more
significant reformatting to make eslint happy (that are not otherwise
actually improvements).
The one area that we do not attempt to work on here is the
"switch/case" indentation.
If notifications_stream is private and the current user has never been
subscribed, then we would throw an exception when trying to look up
notifications_stream. In this situation, we should just treat it like
the stream doesn't exist for the purposes of this user.
Currently, stream subscriptions aren't getting updated without
hard reload when user is deactivated in realm.
Fix this issue by updating stream subscription widgets on user
deactivation event.
Fixes#5623
In stream settings, if user add subscriber to unsubscribed public
stream from `Add` input widget it gives lots of blueslip warnings,
cause user isn't subscribed to public stream.
Fix this by changing condition to `sub.can_access_subscriber` from
`sub.subscribed` in blueslip warning, cause user can access
subscribers in such cases even if not subscribed to stream.
Tweaked by tabbott to make the node tests pass.
This will allow realm admins to access subscribers of unsubscribed
private stream. This is a preparatory commit for letting realm admins
remove those users.
This will allow realm admins to update the names and descriptions of
private streams even if they are not subscribed, which fixes the buggy
behavior that previously nobody could(!).
Also adds a custom rule to eslint. Since the recommended way of extending
eslint is to create plugins as standalone npm packages, the separate rule
is published as 'eslint-plugins-empty-returns'.
Fixes#8669.
For public stream, always show stream preview link.
For private stream, only show stream preview link if user is currently
subscribed or previously subscribed to private stream.
Private streams were not included in stream suggestions for default streams
in org settings.
Remove function, which exclude private streams from stream suggestions
for default streams.
This commit prefixes stream names in urls with stream ids,
so that the urls don't break when we rename streams.
strean name: foo bar.com%
before: #narrow/stream/foo.20bar.2Ecom.25
after: #narrow/stream/20-foo-bar.2Ecom.25
For new realms, everything is simple under the new scheme, since
we just parse out the stream id every time to figure out where
to narrow.
For old realms, any old URLs will still work under the new scheme,
assuming the stream hasn't been renamed (and of course old urls
wouldn't have survived stream renaming in the first place). The one
exception is the hopefully rare case of a stream name starting with
something like "99-" and colliding with another stream whose id is 99.
The way that we enocde the stream name portion of the URL is kind
of unimportant now, since we really only look at the stream id, but
we still want a safe encoding of the name that is mostly human
readable, so we now convert spaces to dashes in the stream name. Also,
we try to ensure more code on both sides (frontend and backend) calls
common functions to do the encoding.
Fixes#4713
When removing the description from a stream (i.e. setting it to ""),
the UI was not correctly updating the description. This is because we
were checking incorrectly for a falsey value, rather than the specific
value undefined (which means the description wasn't changed).
Display warning, saying "You can not access private stream subscribers,
in which you aren't subscribed", if user can not access subscribers;
instead of showing zero subscriber to stream.
For public stream, always show subscription option.
For private stream, if user is subscribed display unsubscribe option.
If user is not subscribe, do not display subscription option.
Only show edit option for stream name and description if user is admin and
either stream is public or stream is private and admin is subscribed to
private stream.
As per backend restrictions for editing stream name/description.
We now return user_ids for subscribers to streams in add-stream
events. This allows us to eliminate the UserLite class for
both bulk adds and bulk removes. It also simplifies some JS
code that already wanted to use user_ids, not emails.
Fixes#6898
We continue to have page_params.realm_default_streams, but
now we do lookups on whether a stream is a default stream
by using a Dict indexed by stream_id.
We are also careful to update that during live updates.
This fixes a flaw that we weren't updating the list of realms
correctly for events that remove a default stream.
This new module tracks the recent topic names for any given
stream.
The code was pulled over almost verbatim from stream_data.js,
with minor renames to the function names.
We introduced a minor one-line function called stream_has_topics.
We now have all of our callers into recent_topics code just
receive a list of topic names from get_recent_topic_names().
This is more encapsulated than handing off tiny little
structures to the three callers, two of whom immediately
mapped the objects to names, and one of whom needlessly
used the now defunct name canon_subject field.
The consolidation here removes some "subject" references, and
now all lookup are by stream id, not stream name.
The diff here is a bit daunting, but it's mostly simplification
of tests and calling code. Two of the callers now need to look
up stream ids, but they are otherwise streamlined.
The main change here is to stream_data.js, and we replace the
`canon_subject` and `subject` fields with `name`.
This commit changes the key for recent_topics to be a
stream id. For streams that have been renamed, we will now
get accurate data on recent topics and active streams as
long as stream_data.get_stream_id(stream_name) returns a
valid value.
This commit changes stream_data.in_home_view() to
take a stream_id parameter, which will make it more
robust to stream name changes.
This fixes a bug. Now when an admin renames a stream
you are looking at, it will correctly show itself to
be un-muted. (Even with this fix, though, the stream
appears to be inactive.)
Some callers still do lookups by name, and they will
call name_in_home_view() for now, which we can
hopefully deprecate over time.
This change fixes a few small things related to stream
renames, such as what happens if you hit the back button
to go to a narrow where the stream had been renamed. You
will now get the correct behavior in terms of filtering
and searching. Unfortunately, this will only last until
you reload.
This is not a user-facing change, but it starts us down the
path to having the JS client be able to look up old stream
names for situations like people clicking old external links
or for live-update scenarios.
We used to have code scattered in multiple places to
calculate things like admin options, preview urls,
subscriber counts, and rendered descriptions for
streams before we rendered templates in the "Manage
Stream" code.
These are all consolidated into a new function
called stream_data.update_calculated_fields().
This is mostly code cleanup, but it also fixes a bug where
the "View Stream" button would not work for a newly created
stream.
When you subscribe to a stream, we now set a newly_subscribed
flag on the object, and we return true during the is_active()
call.
This solves the problem that immediately after you subscribe, you
don't have any messages in the stream, so it would appear active
by our old criteria.
This is still something of a workaround, as once you reload, the
stream will become inactive again, unless other messages come in.
A more permanent solution here would be to have the backend
indicate newly subscribed streams to us (apart from the initial
event), but we may not really need that in practice.
This fixes two bugs:
* If a user is not subscribed to a default stream, he or she would not
be have the option to invite users to that default stream.
* The initial streams checked in the invite modal were the
non-invite-only streams the user was subscribed to, not their
default streams.
Fixes: #4209.
If a url is present in stream description, it will be
rendered as a clickable link under /streams page.
Tweaked by tabbott to use the separate rendered_description element to
avoid duplicate rendering and to live-update.
Fixes#1435.
This adds a button to #subsciption page called "View Stream"
that narrows the user to that particular stream.
This fix involves typical changes to JS/CSS to add new features,
and we also add a "preview_url" field to the sub object in
stream_data.js.
Fixes#3878
If we get invalid events related to stream subscribers, we now
exit earlier to prevent ugly tracebacks. We may eventually
want to upgrade some of these warnings to errors, once we fix some
of our live-update bugs. In particular, we don't yet live-update
users when streams go from private to public, so if you add/remove
subscribers to a newly-public stream that a user still thinks is
private, they will not be able to handle the event through no
fault of the codepath that happens during the add/remove.
When an admin deactivate a stream, we now remove the
appropriate row from the default streams tables for other
folks viewing default streams in the admin tables.
(There was a method with the same name before, but it wasn't
being used. The new version will accept stream_id instead
of name, and we will use it as part of deactivating streams.)
When we subscribe ourselves using the "Add" button in the
right pane of "Stream settings", we now call
stream_data.subscribe_myself(), which properly updates our
data structures (more than just sub.subscribed) and prevents
some console errors when you un-subscribe yourself using
the check mark.
If a new user is auto-subscribed to a stream called "new
members", we will automatically narrow them to that stream
after the tutorial. Otherwise, we fall back to the code's
previous behavior, which is to direct them to the notifications
stream (often called "announce").
This is somewhat experimental. If we try this concept out on
the public Zulip realm and it works well, we will create a nice
realm setting for the "new members" stream.
This is a major change to the /#subscriptions page, converting it to
by a side-by-side list of streams and their settings in an overlay.
There are no new features added/removed, but it's a huge changeset,
because it replaces the old navigation logic and moves the stream
creation modal to appear in the right side of this overlay.
We now use stream_id as our key to rename streams, which
should prevent a few race conditions long term. (We are
still possibly contending with other events that use
stream_name as a key, so this is not perfect.)
We get events to delete subscribers for streams we are not
necessarily subscribed to, and it is now important to
process those events to produce the correct UI for showing
the number of subscribers to streams.
The startup code in subs.js used to intermingle data
stuff and UI stuff in a loop inside a called function,
which made the code hard to reason about.
Now there is a clear separation of concerns, with these methods
being called in succession:
stream_data.initialize_from_page_params();
stream_list.create_initial_sidebar_rows();
The first method was mostly extracted from subs.js, but I simplified
some things, like not needing to make a copy of the hashes
we were passed in, plus I now garbage collect email_dict. Also,
the code path that initialize_from_page_params() mostly replaces
used to call create_sub(), which fired a trigger, but now it
just does data stuff.
Once the data structure is built up, it's a very simple matter
to build the initial sidebar rows, and that's what the second
method does.
This function will make it easier to unit test upcoming
changes related to stream counts.
This was mostly moving code, but one change is that we
don't call create_subs() in subs.js any more (which would
have been kind of circular dependency), since the only thing
that it did besides calling a more appropriate function
in stream_data.js was to generate a trigger that was
subsequently ignored and possibly a UI trap, as we don't
want to be messing with the stream sidebar when we go into
the stream settings page.
We now simply call exports.create_sub_from_server_data() for
newly encountered unsubscribed streams (which don't belong in
the sidebar anyway.)
This function used to live in subs.js. It's mostly a code move,
but I simplified the logic to determine whether it's subscribed
not to do a lookup into the same data structure that the sub
already came from.
I also added some tests.
This moves these functions from subs.js to stream_data.js:
receives_desktop_notifications
receives_audible_notifications
This makes notifications.js no longer dependent on the
bloated subs.js.
The JS code can now call stream_data.get_sub_by_id() to get
a sub from a stream_id. Subs have stream_id due to a prior commit,
and we keep track of the mapping in stream_data's subs_by_stream_id
variable.

The tutorial introduces "engineering" messages that might not
be in the user's normal subscription, and they would get a gray
border if we did not override the stream color. Before this change,
we accomplished this by overriding the core data structure in
stream_data.js. Now we are a bit more future-proof; we only
override stream_color.default_color.

I want to make subscribed_streams() external, but it conflicts with
a legacy name in the same module (stream_data.js), so I have to rename
it in the same commit. The new name conforms better to the current

use "sub" in the name.
