The only reason to use typeof foo === "undefined" is when foo is a
global identifier that might not have been declared at all, so it
might raise a ReferenceError if evaluated. For a variable declared
with const or let or import, a function argument, or a complex
expression, simply foo === undefined is equivalent.
Some of these conditions have become impossible and can be removed
entirely, and some can be replaced more idiomatically with default
parameters (note that JavaScript does not share the Python misfeature
of evaluating the default parameter at function declaration time).

These were introduced in ff9a929d7a
with no explanation of why they were necessary.
Generally you only render a few things, and it's
important that they're up to date.
We weren't doing a good job of invalidating the cache.
Eliminating the cache will fix bugs (like presence circles
being out of date) and break some dependencies.
I removed some very fragile test code that was relying
on invalid values taken out of the cache. (We now have
less line coverage, but if we want to test our rendering,
there are much cleaner ways to do it.)
As part of testing this, I renamed Hamlet to "aaron", so
that there are two aarons, and then I logged on as Iago
to see the "secondary" code in action that shows their
emails to distinguish them.
This add the schema checker, openapi schema, and also a test for
realm/deactivated event.
With several block comments by tabbott explaining the logic behind our
behavior here.
Part of #17568.
This helper was added in eac6463031 and
used by the "message.handlebars" file. This is no current call for
this helper in the codebase, hence it is removed to improve coverage.
This commit also marks template.js to have 100% test coverage.
This adds support for unstarring all (starred)
messages from a particular topic, from the topic
popover.
The earlier implementation of this in #16898
was reverted in bc55aa6a01 (#17429)
because it had two problems-
1. The crash reported in bc55aa6a01
was due to message_store returning undefined. This happens
when the message itself hasn't been fetched from the server
yet, but we know that the message is starred from the ids
in `page_params` in `starred_messages.js`.
This commit handles this case explicitly.
Note that, we simply ignore those messages which
we haven't fetched, and because of this, it may
happen that we don't unstar some messages from that
topic. The correct implementation for this would
be to ask the backend for starred IDs in a topic.
2. The earlier implementation actually unstarred **all**
messages. This was because it grabbed the topic and stream_id
from the topic popover `data` attributes, after the topic
popover had been closed. This passed `undefined`, which
the function then interpreted as an action to unstar all
messages.
With this commit, we use the confirm_dialog widget,
which eliminates the need to store this data in the DOM.
* Currently, the confirm_dialog is used only in
the settings pane, which already has the `new-style`
class in the main `settings_overlay.hbs` file. So,
the confirm modal is rendered correctly there. But to
make it available for use outside of the settings pane,
we add the `new-style` class to the confirm container
itself, without which, the buttons look ugly.
* The other change here is the click handler for
removing the modal element. Previously, when the
modal was closed (with any of the "yes"/"no"/"cross"
buttons), there was a small time interval of around
a second during which the modal had disappeared,
but the background content was still in the faded-out
state. This change fixes this glitch. This glitch was
probably not noticable earlier, because the settings
pane itself causes the background to be slightly faded
out.
This code was added in 2d414fa897, after
the `window.exports` variable was removed from
`stream_popovers.js`, while converting it to an ES6 module
in c71af35461. This resulted
in opening the starred messages or all messages
popovers throw `Error: exports in undefined.`.
Follow up to #14768. This feature was already non-functional due to
.alert-display { display: none; }, and if we want to reimplement it,
we should do it using a modern library.

Remove the unused notifications-area wrapper. Remove the feature
detection code as all browsers recognize the <audio> element. Create
the <audio> statically with the page template. Use multiple <source>s
to let the browser detect the appropriate format instead of trying to
do its job for it. Remove the absurd loop="yes" attribute, which had
fortunately been specified on the wrong element.

This is mostly a refactoring to break the unnecessary
dependency of bot_data on settings_bots.
This is a bit more than a refactoring, as I remove all
the debounced calls to render bots during the
initialization of bot_data. (The debouncing probably
meant we only rendered once, but it was still needless
work.)
We don't need to explicitly render bots during
bot_data.initialize(), which you can verify by loading
"#settings/your-bots" as the home page. It was just an
artifact of how add() was implemented.
Note that for the **admin** screen, we did not and
still do not do live updates for add/remove; we only do
it for updates. Fixing that is out of the scope of this
change. The code that was moved here affects
**personal** bot settings.
Note that the debounce code is quite fragile. See my
code comment that explains it. I don't have time to go
down the rabbit hole of a deep fix here. The puppeteer
tests would fail without the debounce, even though I
was able to eliminate the debounce in an earlier
version of this fix and see good results during manual
testing. (My testing may have just been on the "lucky"
side of the race.) I created #17743 to address this
problem.
The keyboard-shortcuts icon currently has a fix position
causing design related bugs such as overlapping with userlist
in the sidebar.
The fix wraps the invite-more-users link and keyboard icon inside
a div with display property as flex instead of just using the anchor
tags inside the side-bar items.
This mainly extracts a new module called
browser_history. It has much fewer dependencies
than hashchange.js, so any modules that just
need the smaller API from browser_history now
have fewer transitive dependencies.
Here are some details:
* Move is_overlay_hash to hash_util.
* Rename hashchange.update_browser_history to
brower_history.update
* Move go_to_location verbatim.
* Remove unused argument for exit_overlay.
* Introduce helper functions:
* old_hash()
* set_hash_before_overlay()
* save_old_hash()
We now have 100% line coverage on the extracted
code.
I moved four functions, verbatim, to a new module.
They were in message_util before, which led to
filter.js having several accidental indirect
dependencies.
I considered just putting these four functions in
filter.js, but I think it's a nice abstraction boundary
that filter.js delegates actual message parsing, and
the original author apparently had a similar thought
process.
I also wanted to make it so that a casual reader of
filter.js doesn't think we are manipulating DOM. It's
true that we still indirectly require jquery here, but
it's only for parsing, and it seems plausible we would
eventually use a more low-level parser.
I can see us maybe using these functions in something
like MessageListData in the future, so speculatively
splitting them out might future-proof us from some
cyclical dependencies.
I also think it's plausible that we will just modify
our two markdown processors to attach that kind of
metadata to the messages.
Last but not least, I think there might be opportunity
here to simplify the filter tests and remove some of
the zjquery hacks. We would instead just mock the
message_has_* helpers for the filter tests, and then
do more detailed direct testing on the functions
themselves.
The only caller for this function was settings_config,
so we put it there.
For the stream_edit test we no longer mock the function.
(The reason we mocked the function was more about avoiding
the heavy settings_notifications import than the function
itself.) This gives some incidental coverage, but then I
also add some more real coverage on it.
We extract compose_fade_users and compose_fade_helper.
This is a pretty verbatim extraction of code, apart from adding a few
exports and changing the callers.
This change makes the buddy_data module no longer sit "above" these
files in the dependency graph (at least not via compose_fade):
* jquery
* lodash (not a big deal)
* compose_state
* floating_recipient_bar
* message_viewport
* rows
The new moules have dependencies that buddy_data already
had directly for other reasons:
* people
* util
And then buddy_data still depends on stream_data indirectly through
the compose-fade logic for stream_data. Even without compose-fade, it
would depend indirectly on stream_data via hash_util.
Note that we could have lifted the calls to compose_fade out of
buddy_data to move some dependencies around, but it's useful to have
buddy_data fully encapsulate what goes into the buddy list without
spreading responsibilities to things like activity.js and
buddy_list.js. We can now unit-test the logic at the level of
buddy_data, which is a lot easier than trying to do it via modules
that delegate drawing or do drawing (such as activity.js and
buddy_list.js).
Note that we still don't have 100% line coverage on the
compose_fade.js module, but all the code that we extracted now is
covered, mostly via buddy_data tests.
Previously, it was tedious to create actual message
objects in message_store for use in node tests.
This was mainly because, `add_message_metadata`
in message_store has many dependencies and
validation checks. Since it was difficult to create
actual message objects, many tests just mocked
the `message_store.get()` method to return the desired
message.
This commit adds a new helper method (`create_mock_message`)
to message_store, for use in node tests. This just stores
the object passed to it in the `stores_messages` map,
without any validation. We do not add any
default fields to the message object before saving
it from this helper, because doing so would decrease
the utility of this helper, and, if a test
depends on some field having a particular value,
then it would be better to just pass the field: value
pair from the test itself, for readability, rather
than relying on the helper to add the field for us.
This helper allows us to write deeper tests.
This commit also replaces some instances of mocking
`message_store.get()` to use this new helper method.
Previously, if a user had zero total starred messages,
we would still show the "Unstar all messages" in the
left sidebar on opening the starred messages popover.
This commit adds a check to show button only if the
user had non-zero starred messages. This is done
because-
1. The button, when shown when the user has zero
starred messages, is redundant and may be confusing.
2. Clicking on the button when having zero starred
messages sends a zero-length array to the backend,
resulting in HTTP 400 error.
Computed indexing into an object, especially with a user-provided key,
can be dangerous in JavaScript because of nonsense features like
obj["__proto__"]. In this case there’s no vulnerability because the
possible keys are strictly limited by the regex, but it’s always
better practice to use a Map for computed indexing.

This commit removes the unless msg/locally_echoed condition for the
edit content div, which has the consequence of making the "view
message source" widget always available for locally echoed
messages. This ensures that the message source can be seen if a very
long message has been drafted and it fails due to a server-side error
(See #17425 for the original report).
Fixes#17650.
