Steve Howell ba243416e3 stream_color: Make stream color assignment more efficient.
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.

Steve Howell 6035304619 Extract color_data.js.
This code is pretty distinct from all the color-picking UI,
and we want to get it to 100% coverage and optimize it
more.

Yashashvi Dave 8c72adc106 subscribers: Hide subscribers of non-subscribed stream for guest user in UI.
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).

Yashashvi Dave e489923d52 stream settings: Hide subscription button in case of guest user.
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.

Yashashvi Dave ee8948c3e1 default stream: Limit private streams in default stream suggestions.
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.

Steve Howell ecb3879d0c refactor: Break subs dependency in stream_data.
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`.
2018-08-04 14:06:19 -07:00
Steve Howell ab26e27fef Move stream-related uri helpers to hash_util.
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.

Steve Howell 6a4bacbd18 stream settings: Avoid redundant sorting step.
We don't need to get our original items in sorted

Steve Howell 51edcb02c8 Streamline typeahead for stream links.
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.
2018-07-30 11:25:32 -07:00
Steve Howell 064d0f3c89 Extract stream_data.sort_for_stream_settings().
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.

Armaan Ahluwalia 6d255efe4c app: Prepare JS files for consumption by webpack.
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.

Shubham Padia 10a65a62db compose: Display error for non-admin trying to post to announce_only stream.

Tim Abbott 7ab8a8e820 js: Fix a bunch of indentation issues found by eslint.
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.

Tim Abbott 0ada5fa9d8 stream_data: Fix exception when notifications_stream is private.
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.

YJDave 2cbfcbb740 subscription: Fix unexpected blueslip warnings on add subscriber.
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.

Steve Howell 46a49777c4 Add stream ids to urls for stream-related narrows.
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.

YJDave 1f8b6938a7 stream settings: Fix error in updates of stream description.
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).

Steve Howell 3e6bfe1b23 Use user_ids, not emails, for bulk stream operations.
We now return user_ids for subscribers to streams in add-stream

code that already wanted to use user_ids, not emails.

Steve Howell b32a9444dd js: Clean up how we track default stream names.
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.

Steve Howell bc0761b22b Extract topic_data.js.
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.
2017-07-27 14:26:22 -07:00
Steve Howell b95e785335 recent topics: Extract get_recent_topic_names().
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`.

Steve Howell efb35afeb7 Track recent topics (and active streams) using stream id.
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.
2017-05-15 14:47:41 -07:00
Steve Howell c125ba1d08 Fix how we find if streams are muted.
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.
2017-05-15 14:47:41 -07:00
Steve Howell 8b78f3f133 Look up old stream names in stream_data.get_name().
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.
2017-05-13 21:59:08 -07:00
Steve Howell 8ecfda9344 stream_data: Remember old stream names.
This is not a user-facing change, but it starts us down the

or for live-update scenarios.

Steve Howell 4762673929 Fix how we calculate fields in stream_data.js.
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.
2017-04-28 17:49:33 -07:00
Steve Howell 0ced7cfc55 Make newly subscribed streams appear active.
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.
2017-04-28 07:40:25 -07:00

Steve Howell b8caf45262 Improve error checking for peer_add/peer_remove events.
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.

Steve Howell 58fb9e45e4 Fix flaw when subscribing using "Add" button.
When we subscribe ourselves using the "Add" button in the

Steve Howell 477b4af39d Direct new users to the "new members" stream.
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.

Steve Howell 7509f73f02 Clean up stream renaming in the JS code.
We now use stream_id as our key to rename streams, which

stream_name as a key, so this is not perfect.)

Steve Howell 029682ec41 Fix stream_data.remove_subscriber().
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.

Steve Howell 4073ae09a1 streams: Use page_params.neversubbed_info client-side. 2016-10-18 17:33:58 -07:00
Steve Howell 7fd74c45d7 Clean up startup code for 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.
2016-10-17 19:58:23 -07:00
Steve Howell 869a124d7d Extract stream_data.get_streams_for_settings_page().
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.)
2016-10-17 19:58:23 -07:00
Steve Howell 965c6047db Move add_admin_options() to stream_data.js.
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.
2016-10-17 19:58:23 -07:00
Steve Howell cf08f04dbc Move receives_*_notifications() to stream_data.js.
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.

Steve Howell 90f6eb0661 Keep track of subs by stream_id inside of stream_data.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.

Steve Howell 583dae72a3 Change how the tutorial overrides the default stream color.
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.

Steve Howell 20c18d905d Rename internal subscribed_streams() to exports.subscribed_subs().
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
naming convention, which generally has functions returning objects
use "sub" in the name.

Steve Howell b55a2bfc58 Avoid reloading subscribers when opening Streams page.
For a large domain like HS, we were pulling back about 100k of
text with subscriber emails when we opened the Streams page.
This was unnecessary, as the subscribers aren't shown until
you expand the stream, and there's already an AJAX call.

Warn inside these functions when you get data on streams that you

The back end should be smart enough not to spam us with subscriber
info that we don't care about.

2. When a compose is aborted, unfade all users.
3. When the presence list is redrawn, fade/unfade the user list again.
