Some of the work here was done Tomasz Kolek.
When we click on "more conversations" in "Private Messages,"
we call it being "zoomed in." Before this change, when
new PMs arrived, we would rebuild the list and zoom out
again. Now we track the zoomed_in state with a variable.
Also, if you are zoomed in and switch from one PM narrow
to another, we also keep you zoomed in.
This fix also removes some extraneous/redundant code.
Fixes: #2561
I forgot to remove this code in a recent refactoring that copied
this code into activity.js. It should not have caused any errors,
but it's no longer needed.
From subs.js we don't redundantly try to remove an element
from ths sidebar; we just trigger the event.
In stream_list.js we continue to remove the element from
the DOM, and we also remove the widget from our internal
Dict of sidebar rows, so that if we re-subscribe, we know
we'll automatically re-build the widget from the template
and the latest data from stream_data.js.
We used to have hacky code where various functions would call
build_stream_sidebar_row() to get a jQuery object, and then they
would attach the jQuery object to the "sub" object from stream_data.js.
Now build_stream_sidebar_row() localizes the hack of attaching
a UI object to the "sub" object to just one function (and we can
clean this up in a follow-up commit).
Also, the UI object is now a JS object that can close on some useful
state information like the stream name and encapsulate how we
toggle the inactive_stream class.
Finally, we don't have build_stream_sidebar_row() needlessly append
list items to $('#stream_filters') when we know that our callers are
going to re-build the list anyway.
The code removed in this commit added pinned streams to a list
of elems, only to have them added again by the next block of code
(but more concisely). Through some strange quirk of appendTo() this
never created user-facing bugs, but you could clearly see in the console
that it was doing double work.
For cases where we are zoomed in to a stream and then go
to a different narrow (Home, PMs, etc.), we now let
topic_list.zoom_out orchestrate the removal of the topic list
instead of stream_list.zoom_out.
This will help us when we move to a world where topic_list
redraws topic lists on zoom-in/zoom-out, because we won't
waste effort rebuilding lists that are about to be removed.
The flow for topic list zooming is kind of complicated now, but
it's mostly a consequence of the way the UI works.
* stream_list tells topic_list to set up the topic list
click handlers to have callbacks to stream_list
* topic_list click handlers call to stream_list zoom methods
to hide/show all the other streams
* stream_list zoom methods call back to topic_list methods to
redraw topics as needed (this isn't happening yet, but allowing
topic_list.js to know that it's zoomed will set the stage for
this to happen in a more controlled manner)
We no longer use active_stream_name(), which was mostly a
duplicate of narrow.stream(). For nonsensical queries like
"stream:foo stream:bar" the behavior may change slightly here.
We know that we don't handle non-sensical queries particularly
well, but at least if we always go through narrow.stream(),
the behavior will be consistent.
I did test this with some sensible compound narrows, like searching
for a keyword within a stream.
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.)
This change makes most of the logic on set_count() live
on our per-stream topic list widget. We can find the
jQuery object directly now rather than using the
complicated iterate_to_find() method.
This also brought along:
iterate_to_find (copied, see large comment explaining why)
activate_topic (extracted from a one-liner)
set_count (formerly stream_list.set_subject_count)
For get_topic_filter_li, we now pass in stream_li instead of
stream to decouple parent/child responsibilities between the
components.
Also, I made some s/subject/topic/ fixes.
This creates the new topic_list.js module, and the first
function that we extract is topic_list.update_count_in_dom().
This function needed to be decoupled from some non-topic-list
stuff which was overly complicated.
I make server_events slimmer by not handling a specific
property when subs.update_subscription_properties() should
do all the dispatching (and mostly did).
And then since update_subscription_properties() has
a "sub" already, I can call directly to stream_list code
and remove a function from subs.js. Since I lose the
wrapper function in subs.js, I rename the stream_list
function as part of this commit.
The only code that gets slightly heavier here is that
we have two lines in the 'pin_to_top' case instead of one.
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 replaces add_stream_to_sidebar(), which was kind of a misleading
name, and it also adds a couple lines of code that were always
called right after calling add_stream_to_sidebar().
Assigns hotkey 'w' to search streams.
Only show search box when active. Activate with hotkey or by clicking
STREAMS.
Filter matches at the beginning of words in stream name.
Behaviour is otherwise almost identical to user search.
Casper tests.
Like the Stream Subject lists, Private messages are now shown
when the user clicks on the "Private message" link. User can drill in
to get more than 5 conversations. Selecting PMs from the user or group
PM lists on the right sidebar also opens the list & highlights the
selected conversation.
[Edited by tabbott@mit.edu to fix some small bugs.]
Before this change, we were using sequentially generated ids
on the client side to identify streams. Now we just use
the ids from the server. The goal here is to reduce the
confusion of having two different ids attached to a stream.
Also, not that it matters a ton, but this also means that
the browser basically has an immutable id for each stream
that is future-proof to reloads, multiple create_sub calls, etc.
It also a bit easier to grep for ".stream_id" than ".id".

This function can redraws the lock icon (or lack of lock icon)

The new name is more descriptive of what the function does, and it
also has the side benefit of cleaning up greps for the backend
function called build_narrow_filter().

The type parameter was always passed in as "stream", and we

We now call add_stream_to_sidebar() instead. The old function was

This is a node test that verifies that
stream_list.add_stream_to_sidebar() creates the right
DOM when it renders the stream_sidebar_row template.
The test also makes sure that the DOM gets put in the
correct place to be retrieved by stream_list.get_stream_li()
calls.

In the first cut at topic zoom, I was re-rendering the
streams list, but this created glitches with orphaned
list items. The reproducible bug was that unread counts
on unshown streams weren't updating.
In the new approach, I keep the elements more permanent, and
I just hide and show them as needed, either through jQuery
show/hide or permanent CSS selectors.
I got rid of toggle_zoom(), so that we just explicitly zoom
in and zoom out in all situations. In particular, when we
narrow, it's more clear now that only stay zoomed in when
we're narrowing to the same stream as before (including topic
narrows within that stream).
When you zoom in, the number of topics is no longer limited
to 30, since that was kind of arbitrary anyway. (In practice,
the number of topics is usually well under 30, anyway, due to
the way we track them on the client.)
(imported from commit 5b6c143dee9ba9fe557d8cc36335ff28efb4b0de)
This link lets you zoom in to more topics. We only show it if
there are topics that we had to hide to respect the max-5 limit
along with other rules of when you show topics.

If you double-click on a stream that you've narrowed to, it
will either zoom in or zoom out the left sidebar view. Zooming
in shows just that stream; zooming out shows all streams.

This commit doesn't actually add the final UI to zoom/unzoom
topics, because I want to keep those in separate commits, in
case we change how to enable the feature. But this commit
adds a toggle_zoom() function that zooms/unzooms topics.
Zooming is minimally invasive, because we don't really introduce
many extra elements to the UI; instead, we just make the list of
streams be a list of length one (i.e. the active stream). This
gives us a lot of stuff for free, basically, like unread counts, etc.

Show up to 10 of your recent group PM conversations in the right

Some of this code was written by Allen before commits were squashed.

We want to deprecate reload_subscriptions(), which was kind
of a big hammer to use when only a single stream is being
renamed. Now we call stream_list.rename_stream() to update
the sidebar.

Before this change, you could narrow to an old topic, and it would
not show up in the sidebar unless it had unread messages.

The old code was looping through recent_subjects to find the
original subject name, but we already have logic in get_subject_filter_li()
to be case-insensitive. I tried this with various casings of topics,
narrowing to topics, as well as narrowing to a stream (so no active topic)
and narrowing to an old topic.

This was broken in two ways:
1. Commit ad59d6f78042ce89, "Make the left sidebar and right sidebar
more consistent", pushed last Monday, changed the markup for the right
sidebar without changing a selector in stream_list.js that was looking
for the old markup.
2. Even then, whenever new user presence information came in, we would
rerender the user list and blow away the unread counts. This commit
patches around that by updating unread counts after rendering the user
list. I'm not sure what broke this or how it was working before.

There are also one or two places we don't need to use it for security

In a few cases the $.each was doing something imperatively that was
terser and easier to understand by using a different Underscore method,
so a few of these I rewrote.
Some code was using the fact that jQuery sets `this` in the callback to
be the item; I rewrote those to use an explicit parameter.
Some code was using $(some selector).each(callback). I converted these
to _.each($(some selector), callback).
One function, ui.process_condensing, was written to be a jQuery $.each
callback despite being in a totally different module from code using it.
I noticed this and updated the function's args.
