Steve Howell a3d3d08a80 refactor: Avoid positional params for MessageList.
We used to have positional parameters for table_name
and filter, but we don't use them for message_list.all
and we're about to replace filter in some cases.

Passing everything in on opts is more consistent and
self-documenting in the calling code, plus lots of
unit tests can get away with passing in `{}` now
for situations where table_name does not matter.

All of our callers pass in muting_enabled, so we
remove the default value for it.  And then the
collapse_messages variable doesn't have to live on
`this` as it's only being passed through down to the
view.

Steve Howell f61ecef138 refactor: Cleanly divide data/view for add_messages.
Before this change, the way to add messages had a lot
of ping-pong-ing between MessageList and MessageListData,
where first the data got triaged, but not actually
inserted into data structures, and then subsequent
calls would add the data and get filtered results.

Now we have a simple API for MessageListData.add_messages
that does all the data stuff up front.  Having a fully
function MLD.add_messages not only makes the ML.add_messages
function about four lines shorter, it also sets us up
to easily build standalone MLD objects before making
the heavier ML objects.

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.

Steve Howell 264dcb6f40 refactor: Extract MessageListData class.
Most of this was straightforward.

Most functions that were grabbed verbatim and whole from
the original class still have one-line wrappers.

Many functions are just-the-data versions of functions that
remain in MessageList:  see add, append, prepend, remove as
examples.  In a typical pattern the MessageList code becomes
super simple:

    prepend: function MessageList_prepend(messages) {
        var viewable_messages = this.data.prepend(messages);
        this.view.prepend(viewable_messages);
    },

Two large functions had some minor surgery:

    triage_messages =
            top half of add_messages +
            API to pass three lists back

    change_message_id =
            original version +
            two simple callbacks to list

For the function update_muting_and_rerender(), we continue
to early-exit if this.muting_enabled is false, and we copied
that same defensive check to the new function
named update_items_for_muting(), even though it's technically
hidden from that codepath by the caller.

Steve Howell da0c01e4ba Fix regression with topic edits clearing narrows.
We had a recent regression that had kind of a funny symptom.
If somebody else edited a topic while you were in a topic
narrow, even if wasn't your topic, then your narrow would
mysteriously go empty upon the event coming to you.

The root cause of this is that when topic names change,
we often want to rerender a lot of the world due to muting.
But we want to suppress the re-render for topic narrows that
don't support the internal data structures.

This commit restores a simple guard condition that got lost
in a recent refactoring:

        see 3f736c9b06

From tabbott: This is not the correct ultimate place to end up,
because if a topic-edit moves messages in or out of a topic, the new
behavior is wrong.  But the bug this fixes is a lot worse than that,
and no super local change would do the right thing here.

Tim Abbott 3f736c9b06 message_list: Clean up API for rerender_after_muting_changes.
This was only called from two places in one function, and we can just
check muting_enabled in the caller.

This refactor is important, because we might need to update muting
after other changes (specifically, message editing to move a topic to
be muted/non-muted).
2018-04-27 08:52:24 -07:00
Tim Abbott dbbd3627b5 message_list: Show empty narrow notice after emptying narrow.
If muting, topic editing, or deletion causes a narrow loses its last
message, we should show the empty-narrow notice; similarly, if
un-muting adds the first message, we should hide the notice.

We do this in `rerender()` since that's the common code path for
re-rendering the message list after events that might change this.

This has likely been broken since the very first muting
and topic editing implementations.

2018-03-30 11:52:14 -07:00
Steve Howell bcdd12773e Ignore new messages when lists are behind.
If individual messages arrive before we get the latest
messages from the server, they can create gaps in rendering,
and would often be offscreen anyway, so we just ignore them.

Fixes #8669.
2018-03-13 08:22:42 -04:00
Steve Howell 616a06e5b2 Use msg_list.fetch_status instead of load_enabled.
We now attach a fetch_status to message lists, so that they
can track their fetch status individually.  When you go
back in a narrow and get all the older messages, we turn
off future fetches.

The narrow.js code no longer needs to orchestrate anything
here.  The "home" message list won't have as many redundant
fetches after this commit, because we don't need to reset
flags every time we do `narrow.deactivate`.

And then actual narrows get a new message list every time
you narrow, so their fetch status gets reset implicitly
as part of constructing the MessageList object.

Tim Abbott c1f12e3f8a scrolling: Fix out-of-order bug in the message list.
The issue has a lot of extra details, but in short, if several
messages were sent at very close to the same time, it's possible that
the event queues will receive the "new message" events out-of-order.
This, in turn, could cause `get_events` to return an incorrectly
sorted block of messages.  These would then be passed into
`message_list.add_messages`, which doesn't handle that sort of
unsorted situation correctly (in short, the `self.first.id()`
comparison checks are not accurate for that situation, since we don't
update the boundaries after the first messages is processed).

The end result of this bug was that it was possible for the message
list to be out-of-order, which in turn would cause exceptions when
scrolling with the mouse.

Fixes #6948.

Tim Abbott 3c8eb3c743 message_edit: Create recipient_bar_controls span.
This refactor will facilitate making it possible to set CSS properties
on this controls span; in particular, we're hoping to disable user
selection of the whitespace in this region.

The main side effect of this refactor is that we need to add JS code
to also hide the icon-vector-pencil element, since it's now in a new
span.

Akhil b6b22fbb47 message-edit: Trigger mouseleave on row when hiding message_edit div.
For the pencil icon to appear, message_unhover has to be called before
message_hover (both in ui_init.js). This happens when the mouseleave
event is triggered on a row. But, when clicking the save button and
the edit box is hidden, the mouseleave event is not triggered and
hence message_unhover not called.

Fix this with a manual mouseleave event.

Fixes: #4287.

Steve Howell 8eb86335b9 Extract narrow_state.js.
Despite the length of this commit, it is a very straightforward
moving of code from narrow.js -> narrow_state.js, and then
everything else is just s/narrow.foo()/narrow_state.foo()/
(with a few tiny cleanups to remove some code duplication
in certain callers).

The only new functions are simple setter/getters that
encapsulate the current_filter variable:

    narrow_state.reset_current_filter()
    narrow_state.set_current_filter()
    narrow_state.get_current_filter()

We removed narrow.predicate() as part of this, since it was dead
code.

Also, we removed the shim for narrow_state.set_compose_defaults(),
and since that was the last shim, we removed shim.js from the app.

Steve Howell 293c89ba94 message edit: Only enable left-arrow-editing for content.
We no longer let the left arrow put you into the message edit
UI for a message where you can only edit topics, since that is
just confusing to most users.

This change also improves error handling a bit, and it removes
an unnecessary call to rows.id().

Finally, it moves some logic out of message_list.js, so that we
don't have a circular dependency for this codepath.

Fixes #4259

Tim Abbott 5e39ccd642 js: Rename viewport.js to message_viewport.js.
This fixes the mobile web experience for Chrome on iOS.

Apparently, Chrome-on-iOS silently has a `viewport` module that
overrides and user-defined module by that name, causing all of our
code that accesses the viewport module to not work on that platform.
We fix this by renaming it.

Steve Howell 03386f1485 avatar live updates: Do full re-render.
We now sweep all active messages for avatar changes and update
the message items and re-render, rather than patching the
DOM.  This avoids some quirks that happen when subsequent messages
get sent and we re-render previous messages out of the message
store.

Our approach here is similar to how we do full-name updates.

Steve Howell 90fa797f9b Use stream id to live-update messages for name changes.
When we change a stream name, we now use the stream id as the

This commit introduces message_live_update.js.

The new call stack is this:

    subs.update_subscription_properties
    subs.update_stream_name
    message_live_update.update_stream_name

Zev Benjamin 3f0fa363f9 Add explanatory comment
Leo and I were looking over this code and I couldn't remember what it
was doing.  So after I re-derived its purpose, we figured that an
explanatory comment was in order.

Kevin Mehall bd58861b09 Ignore summarized messages when calculating rendering windows.
Summary blocks can contain hundreds of messages. When the rendering window
code didn't take this into account, it would lead to all kinds of
unpleasant behavior when you scroll.

Trac #1888

Unfortunately, this replaces a subtraction with a function that iterates
through all the messages.

Steve Howell ec1c82d6d7 Select closest id in MessageList.rerender().
When we call rerender() on MessageList, it is usually because
something big has happened, so it's reasonable that the pointer
may now be invalid.  As an example, the old pointed-to message
may been removed from the home view.  We have always just
moved the pointer under the hood, but now we do it in a way
that doesn't generate spurious blueslip errors.

Steve Howell f67acb3157 Filter duplicate messages more aggresively.
This fixes a blueslip error where we were trying to add the same
message into a MessageList twice.  Muting complicates our duplicate
detection, because empty() can return true even when we already
are storing messages that just aren't shown (because of muting).

The name empty() should probably be fixed in light of muting,
but filtering with self.get() is not really a problem here.
