In both cases, `args` is a local variable that goes out of scope
immediately after the assignment. Since the variable isn't captured by
a closure either, the assignment has no effect.
This fixes a confusing bug where administrators would be offered the
convenient topic-edit pencil even if message editing was actually
disabled.
This doesn't yet fix the real-time sync issues of changing the setting
without reloading.
Fixes#5946.
Normally the "n" key skips over muted streams, but if we
are currently narrowed inside a muted stream, it will now
go to the next topics within that stream.
For me the use case was that I have a stream I check up on
about once a day, and "n" would be super useful for me to
clear out unread counts while still skimming some content,
and without having to temporarily unmute the stream.
This causes `upgrade-zulip-from-git`, as well as a no-option run of
`tools/build-release-tarball`, to produce a Zulip install running
Python 3, rather than Python 2. In particular this means that the
virtualenv we create, in which all application code runs, is Python 3.
One shebang line, on `zulip-ec2-configure-interfaces`, explicitly
keeps Python 2, and at least one external ops script, `wal-e`, also
still runs on Python 2. See discussion on the respective previous
commits that made those explicit. There may also be some other
third-party scripts we use, outside of this source tree and running
outside our virtualenv, that still run on Python 2.
We now use similar code for A/D hotkeys as we do for the "n"
key.
The old code was using jQuery operations that got tripped up
by our splitters between active and inactive streams.
Fixes#4569
This allows us to traverse a list backwards, cycling to the
bottom as needed.
This code is going to be used for the "A" key that cycles
upward in the stream sidebar. It's probably overkill for
that use case, but it does give us O(1) behavior and avoids
the pitfall of accidentally mutating a list when reversing it.
This is the first part of a larger migration to convert Zulip's
reactions storage to something based on the codepoint, not the emoji
name that the user typed in, so that we don't need to worry about
changes in the names we're using breaking the emoji storage.
Here are the functions in top_left_corner:
get_global_filter_li: pure code move
update_count_in_dom: simplifed copy of similar function in stream_list.js
update_dom_with_unread_counts: pure code move, split out from function
of same name in stream_list.js
delselect_top_left_corner_items: pure code move
handle_narrow_activated: pure code move + rename
handle_narrow_deactivated: pure code move, split out from from function
of smae name in stream_list.js
Until we have an easy way to consistently determine whether a
stream has more topics than have been loaded already, we err
on the side of showing a "more topics" link. This in some ways
leads to a more consistent experience where you can zoom in on
any stream, even one that's really new.
This fix simplifies how we re-render topic lists when we
re-narrow or zoom out from a topic list.
* The topic_list.zoom_out() no longer gets called as
part of re-narrowing, and we eliminate the clear_topics
option.
* For all situations where we narrow to a filter that does
not have a topic, we simply call the new function
clear_topics().
* The stream_list code no longer calls remove_expanded_topics()
in cases where the new narrow has a topic. This allows us
to optimize away scroll/flicker churn a little more easily.
As part of this, we rename maybe_activate_stream_item() to
update_stream_sidebar_for_narrow(), since the function clears
stuff as well as turning stuff on.
We have code that can automatically scroll an element into "view"
in its container. We use this for stream sidebar rows inside the
stream list.
Generally the stream sidebar rows are small enough to fit into
the container, and the prior algorithm worked correctly for that
scenario.
If you have lots of topics, however, and a short screen, the
algorithm was being too aggressive. For example, if the top
wasn't showing, it would scroll the top into view, but at the
cost of scrolling the bottom out of view.
This fix makes the general scrolling algorithm more tame.
Part of the user-facing problem is that the element we pass
into the scrolling code for the stream sidebar rows is bigger
than the part of the row that actually should be shown on
screen. Nevertheless, it makes sense here to make the general
algorithm more robust.
If you read a message, then got a topic edit for it, we were
adding the message to our data structure of unread stream/topic
messages.
Now we guard against this in unread.update_unread_topics. I
no longer expose an update() method in unread_topic_counter,
since we really want to do the unread check at a higher level
to keep other data structures consistent.
We no longer use real jQuery to test topic_list. This changes
the nature of the tests to be higher level checks on how the DOM
is constructed. The actual details of how templates get
rendered should be in templates.js.
We are phasing out the following in tests:
add_dependencies - this is just kind of a clunky UI
require - normal JS requires cause test leaks
In order to plug require leaks, we are effectively doing what
we always have done inside of add_dependencies, which is to
keep track of which modules we have done `require` on, and
these get cleared between tests.
Now we just use `zrequire` every time we want to pull in real
code to our global namespace.
This code adds 'read' to message.flags and sets message.unread
to false.
It's not clear that the boolean message.unread is used in any
meaningful way, but we set it to false to avoid confusion. The
bankruptcy code was not doing this before.
Another quirk that existed before was that you could get two
'read' flags in a message when you declared bankruptcy. It's
also plausible that this could happen if you marked a message
as read via two different ways. It probably did not cause
user-facing bugs, but it would be confusing for troubleshooting.
Fixes#5032.
The new method borrows some code from the event loop
and unread_ops.mark_messages_as_read, and it is now
flexible about message_ids being marked as unread
even when there is no corresponding message in the
message store. For that scenario we still want to
update our data structures, which wasn't happening
before this change. (Generally, this was a non-issue
up until now, but it will become a bigger issue when
we start loading unread message ids from the server.)
This function allows us to see whether unread.js thinks a message
id is unread (as opposed to looking at the message itself). This
method is useful when we get notifications from the server that a
message has been read. In the future, we may not actually have
a local copy of an unread message, but we'll still know that it is
unread based on page_params. We'll want to update the data in that
case.
Going forward, we'll want to deprecate message.flags for most use
cases and just use the unread.js data structures to track unread
messages.
The prior implementation was needlessly complex. Both del() and
add() are cheap and idempotent.
With this change we no longer bother to delete a topic from a
dictionary when its last message is mark as read, since it doesn't
really help performance. We add a line to the tests to maintain
100% line coverage.
It's not always clear whether user_ids are strings or integers, so
we explicitly convert them to integers for sorting when creating
keys for PMs.
To keep the tests passing, this commit removes some unneeded
defensive code in message_store.js that only applies to contrived
test input.
