The reason for this change is that, this is where `Filter` and
actual tracking of what messages are contiguous lives. This
will be beneficial when we will to move to a model where we
cache `MessageListData` objects for a large number of views.
We shouldn't add redundant data to page_params. Since we already have
page_params.realm_notifications_stream_id, we can use that value instead
of creating page_params.notifications_stream.
We, however, still need the name of the notifications stream to render
it in templates. Thus we create stream_data.get_notifications_stream().
This change adds a toggle widget to the "add streams" page that
lets the user change the sort order of the streams list. So far,
this supports sorting by stream name, by number of subscribers,
or by estimated weekly traffic.
`stream_topic_history` is a more appropriate name as this
module will contain information about last message of a
stream in upcoming commits. Function and variable names
are changed accordingly like:
* topic_history() -> per_stream_history()
* get_recent_names() -> get_recent_topic_names()
* name -> topic_name
We now use `assert.throws()` to test that we're
properly calling `blueslip.fatal`.
In order to not break line coverage here, we have
to remove an unreachable `return` in `stream_data.js`.
Usually we test `fatal` for line coverage reasons.
Most places where we use `blueslip.fatal` fall in
these categories:
* the code is theoretically unreachable, but
we have `blueslip.fatal` for defensive reasons
* we have some upstream bug that we should just
fix
* the code should recover gracefully and just
use blueslip.errors()
It's possible that we should eliminate `blueslip.fatal`
from our API and just throw errors when really important
invariants get broken. This will make it more obvious
to somebody reading the code that we're not going to
continue after the call, and `blueslip` already knows
how to catch exceptions and report them.
This function returns a list of objects to create a
list_render object, and each item contains the streams
whose atleast one notification setting differs from the
default set by the user.
This is done by comparing the global settings in the
`#settings/notifications` page with those settings
present in the subscribed streams.
Work towards #9228.
We now only use `page_params.realm_default_streams` during
initialization, and then after that we use `stream_data`
APIs to get default stream ids and related info. (And
for the event that replace the data, we just update our
internal data structures as well.)
Long term we should have the server just send us ids here,
since we are now hydrating info from stream data in all places.
This code is a bit simpler.
The previous code was concatenating two lists
and then removing duplicates by calling filter().
Now we just have two loops that append to a single
list, and the second loop detects duplicates
before inserting into the list.
We also now use `default_stream_ids` instead of
`page_params` data, which is convenient for two
reasons:
- working with sets of ids is convenient
- we don't need to maintain `page_params`
data any more
We only used get_default_stream_names() in a
test, so now it's being replaced with a function
that just gets ids.
We'll have use for get_default_streams_ids()
in an upcoming commit.
We want to move more logic to stream_data to facilitate
testing.
Both before and after this commit, we essentially build a
new list of users for typeahead, but now the new list
excludes subscribed users. We can do even better than
this in a follow-up commit.
This cleans up the handoff of page_params
data between ui_init and modules that
take over ownership of page_params-derived
data.
Read the long comment in ui_init for a bit
more context.
Most of this diff is actually test cleanup.
And a lot of the diff to "real" code is
just glorified `s/page_params/params/`
in the `initialize` functions.
One little oddity is that we don't actually
surrender ownership of `page_params.user_id`
to `people.js`. We could plausibly sweep
the rest of the codebase to just use
`people.my_user_id()` consistently, but it's
not a super high priority thing to fix,
since the value never changes.
The stream_data situation is a bit messy,
since we consume `page_params` data in the
initialize() function in addition to the
`params` data we "own". I added a comment
there and intend to follow up. I tried
to mostly avoid the "word soup" by extracting
three locals at the top.
Finally, I don't touch `alert_words` yet,
despite it also doing the delete-page-params-data
dance. The problem is that `alert_words`
doesn't have a proper `initialize()`. We
should clean that up and have it use a
`Map` internally, too.
This is not always a behavior-preserving translation: _.defaults
mutates its first argument. However, the code does not always appear
to have been written to expect that.

This moves some code from settings_display.js
into the new module settings_config.js.
Extracting this module breaks some dependencies
on settings_display.js (which has some annoying
transitive dependencies, including jQuery).
In particular this isolates stream_data from
from settings_display.js.
Two of the three structures that we moved here
weren't even directly used by settings_display.js,
since we do a lot of rendering in the modules
admin.js and setting.js.
We make get_all_display_settings() a function
to avoid a require-time dependency on page_params.
Breaking the dependencies simplifies a few
node tests.
Most of the node test complexity came from the
following commit in March 2019:
5a130097bf
The commit itself seems harmless enough, but
dependencies can have a somewhat "viral" nature,
where making stream_data depend on settings_display
caused us to modify four different node tests.
We now treat util like a leaf module and
use "require" to import it everywhere it's used.
An earlier version of this commit moved
util into our "shared" library, but we
decided to wait on that. Once we're ready
to do that, we should only need to do a
simple search/replace on various
require/zrequire statements plus a small
tweak to one of the custom linter checks.
It turns out we don't really need util.js
for our most immediate code-sharing goal,
which is to reuse our markdown code on
mobile. There's a little bit of cleanup
still remaining to break the dependency,
but it's minor.
The util module still calls the global
blueslip module in one place, but that
code is about to be removed in the next
few commits.
I am pretty confident that once we start
sharing things like the typeahead code
more aggressively, we'll start having
dependencies on util. The module is barely
more than 300 lines long, so we'll probably
just move the whole thing into shared
rather than break it apart. Also, we
can continue to nibble away at the
cruftier parts of the module.
We just get the stream_name from the sub struct now.
This mostly affects node tests.
The only place in real code where we called add_sub()
was when we initialized data from the server.
Babel strict generates more code for [...x] than you’d like, while
Babel loose mode assumes x is an array.

This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.
It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.
This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.
With many tweaks by tabbott to documentation under /help, etc.
Fixes#13616.
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 .
Tweaked by tabbott to fix real-time synchronization issues.
Fixes: #13429.
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.
