Steve Howell 7c8dd45da3 node tests: Simplify message_list overrides. 2020-07-26 12:50:07 -04:00
Steve Howell b8b2e31463 zjsunit: Require explicit set_global for overrides.
This forces us to more explicitly document at the
top of the file what dependencies we are stubbing,
plus it's less magical.

Also, we may want to do occasional audits of
set_global to clean up places where we mock
things like stream_data, which are probably just
easier to use the real version of now that we
have cleaner APIs to set up stream data.

The modules most affected by this change are our
dispatch-oriented tests--basically, all the
modules that test handling of Zulip events
plus hotkey.js.

Ryan Rehman 3b5ba6b2c1 message list: Change locally echoed message ids synchronously.
There is a bug and race issue that occurs when a message is selected
while we are in the process of reifying a locally echoed message,
raising the "Selected message id not in MessageList" error.
The code flow to get the exception is as follows:

* A user sends a message to the current narrow we are in.
* Before the new message event is received, we sent a message to
  the same message list which renders it with a locally echoed id.
* One of the ways of getting the exception is to already have the
  locally sent message selected, before receiving an acknowledgment
  from the server.
* Thus the Message List Data's `selected_id` now points to the new
  message id. The exception is raised on entering the `was_selected`
  if block inside `message_list_view` which tries to re-select the
  message.

Updating the `_rerender_message` code for this special case won't fix
the entire bug because, as mentioned above there are other ways of
getting the exception:

Ideally, after all our synchronous work (`echo.process_from_server`)
has completed we would expect the re-order and re-render work of the
`change_message_id` would occur first, due to the timer of the
setTimeout being set to 0.

However as evident from the race condition existing, this isn't always
the case. `change_message_id` function is responsible for 3 things:
updation, re-ordering and re-rendering.
The first one which is responsible for updating the message list's
local cache, occurs synchronously while for the latter two, they both
occur asynchronously.

Before the setTimeout which is responsible for the latter two actions,
is encountered the user might select the message by clicking or more
commonly by scrolling, which causes this message selection event to be
ahead of the setTimeout in the callback queue.
During this time frame, our race condition takes place.

And even though the message id is updated it's Message List is not
in the correct sort order, which leads to `closest_id` !== `id` in
`MessageList_select_id` being true and raising the exception.

Now, we only asynchronously call the re_render function, to guarantee
the data is always correct and UI updates should be done at the end.

Extended by tabbott to comment the setTimeout call.

Fixes #15346.

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.

Anders Kaseorg 28f3dfa284 js: Automatically convert var to let and const in most files.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`.  It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

Tim Abbott edee1251c8 message_list: Replace buggy rerender_the_whole_thing.
As it turns out, our rerender_the_whole_thing function (used whenever
we were adding messages and discovered that the resulting message list
would be out-of-order) was just broken and scrolled the browser to a
random location.

This caused two user-facing bugs:

* On very fast networks, if two users sent messages at very close to
  the same time, we could end up with out-of-order message deliveries,
  triggering this code path, which was intended to silently correct
  the situation, but failed.

* In some narrows to streams with muted topics in the history but some
  recent traffic, the user's browser-cached history might have some
  gaps that mean the server fetch we do after narrowing discovers the
  history is out-of-order, again triggering the
  rerender_the_whole_thing code path.

The fix is to just remove that function, adding a new option to the
well-tested rerender_preserving_scrolltop (which has explicit logic to
preserve the scroll position) instead.

Fixes #12067.  Likely also fixes #12498.

Steve Howell 37c78abe14 frontend: Use topic on message.
This seems like a small change (apart from all the
test changes), but it fundamentally changes how
the app finds "topic" on message objects.  Now
all code that used to set "subject" now sets "topic"
on message-like objects.  We convert incoming messages
to have topic, and we write to "topic" all the way up
to hitting the server (which now accepts "topic" on
incoming endpoints).

We fall back to subject as needed, but the code will
emit a warning that should be heeded--the "subject"
field is prone to becoming stale for things like
topic changes.

Steve Howell a8718c9051 muting: Use stream_id for internal data structures.
This fixes the most core data structures inside of
muting.js.  We still use stream names for incoming
data to set_muted_topics and outgoing data from
get_muted_topics.

This will make us more resilient to stream name changes.
Before, if you were logged on when a stream rename
occured, topics that were muted under that stream would
appear to be unmuted.  (You could fix it with a reload,
but it can be jarring to have a bunch of unread messages
appear in your feed suddenly.)

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.

This run_test helper sets up a convention that allows

complications, since we often intentionally leak
setup in tests.)

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.

Tim Abbott 459421d045 eslint: Update node tests to use new comma-dangle rules.
* In most cases, eslint --fix with the right comma-dangle settings was

* The exceptions were cases where the parser incorrectly treated the
  arguments to functions like `assert_equal` as arguments; we fixed
  these manually.  Since this is test code, we can be reasonably
  confident that just fixing the failures suffices to correct any bugs
  introduced by making changes automatically.
