Steve Howell a175ce65cf minor: Inline add_sub into create_sub_from_server_data.
We now use add_sub only in tests.

The line to defensively initialize subscribers does
not get copied from add_sub, since we know that
create_sub_from_server_data always initializes
subscribers via set_subscribers.

Anders Kaseorg d72423ef21 eslint: Replace empty-returns with consistent-return.
Instead of prohibiting ‘return undefined’ (#8669), we require that a
function must return an explicit value always or never.  This prevents
you from forgetting to return a value in some cases.  It will also be
important for TypeScript, which distinguishes between undefined and
void.

sahil839 67ea4bd937 stream: Fix incorrect dispaly of stream notifications settings.
The stream notification settings checkboxes were not checked
even when the notifications were turned on for the stream.
This was happening because we were passing stream name to

This commit fixes the bug by passing stream id to
receives_notifications. This change should have been done
in f3604fb while refactoring receives_notifications to use
stream id instead of name.

sahil839 66dc712830 compose: Modify validate_stream_message to check invalid stream name early.
We change validate_stream_message to check the existence of stream from
the stream name in compose box early and we then pass stream_id or the
obtained sub objects accordingly to other validate functions.

Passing stream_id or sub objects to these functions, enables us to use
stream_id instead of stream name in stream_data.get_subscriber_count.

stream_data.get_stream_post_policy is also removed as we only used it in
validate_stream_message_policy, but we do not need it now as we can get
stream_post_policy directly from sub object obtained by early check of
valid stream name.

sahil839 791e5de5de api: Remove is_old_stream property from the stream objects.
This commit removes is_old_stream property from the stream objects
returned by the API. This property was unnecessary and is essentially
equivalent to 'stream_weekly_traffic != null'.

We compute sub.is_old_stream in stream_data.update_calculated_fields
in frontend code and it is used to check whether we have a non-null
stream_weekly_traffic or not.

Fixes #15181.

Ryan Rehman 3dff6c0de7 subscriptions: Update wildcard mentions notify on stream create.
The `wildcard_mentions_notify` key was missing from the initial
sub data when a new stream was created. Thus `wildcard_mentions_notify`
was undefined and `wildcard_mentions_notify_display` was false.
(This key is used to render the data in the templates)

This caused a bug where the wildcard notifications was unchecked
in the stream personal settings and the newly created stream was
displayed in the stream specific notifications table.

We shouldn't add redundant data to page_params. Since we already have

of creating page_params.notifications_stream.

it in templates. Thus we create stream_data.get_notifications_stream().

Steve Howell 9943a07e8c node tests: Improve handling of blueslip.fatal().
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.

Ryan Rehman c759083cb8 notification settings: Add helper function for stream notifications.
This function returns a list of objects to create a

This is done by comparing the global settings in the
`#settings/notifications` page with those settings
present in the subscribed streams.

Steve Howell 2cd9c77979 refactor: Stop using page_params.realm_default_streams.
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.

Steve Howell ba495e57eb refactor: Simplify get_invite_stream_data().
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

excludes subscribed users.  We can do even better than

Steve Howell da79fd206a ui_init: Handle page_params more cleanly.
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.

Steve Howell 5e8279c2fb refactor: Extract settings_config.
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.
2020-02-21 12:06:31 -08:00
Steve Howell 9ab07d1038 util.js: Remove util from window.
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.

Ryan Rehman 174b2abcfd settings: Migrate to stream_post_policy structure.
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.

Steve Howell c2af2c1fd1 refactor: Extract is_subscriber_subset().
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);
    });

Steve Howell ee3e488e02 js: Extract FoldDict class.
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.

Steve Howell 631811e686 streams: Add BinaryDict for stream_data.
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.

Steve Howell a3512553a8 streams: Add LazySet for subscribers.
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).

Steve Howell e804f39f0e performance: Avoid expensive call in stream_data.is_active.
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`.

Nat1405 d5f005fd61 wildcard_mentions_notify: Add per-stream override of global setting.
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.

Harshit Bansal b553507412 subscriptions: Migrate notification setting defaults model.
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

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.
