This commit makes the `loading_older_messages_indicator` similar
to the `loading_newer_messages_indicator`.
Now all the decisions about whether to show a loading indicator
will be made from the `fetch_status` API. We still hide the
indicators everytime the view is changed, as explained in the
previous commit.
As explained in 67053ff479,
multiple message fetches may be taking place at the same time.
So some other narrows / the home message list's indicator might
get shown for the current narrow.
This commit moves the updation of the indicators display logic
to the `fetch_status` API.
Now the `loading_newer_messages_indicator` gets displayed along
with the `loading_newer` = true updation for that narrow's message
list, i.e. just before we send the API request. But only if the
message list we are fetching matches with our current message list.
The same indicator is hidden similarly, along with the
`loading_older` = false updation for that narrow's message list,
i.e. just after the success response is recieved. But only if
the message list whose data we recieved matches with our current
message list.
Also the indicators are hidden everytime we activate narrow
or deactivate narrow (`home_msg_list`). And on entering
`narrow.activate` we fetch for it's messages so they get
displayed again, if need be.
This is the reason `message_scroll.hide_indicators();` was
moved to a location above `fetch_messages`.
Fixes#15374.
The streams:all advertisement notice in search should only appear
after all results have been fetched to indicate we've gotten to the
beginning of the target feed.
The notice gets hidden at the start of `narrow.activate` and is
shown just after we've fetched an older batch of messages if the
"oldest" message has been found.
Previously it would get displayed after the first fetch which
takes place from `narrow.activate`. Thus we move this logic to
`notifications.hide_or_show_history_limit_message` which gets
called after a successful message fetch.
Since the home message view contains all the messages we are not
required to display this notice. However if it is already shown
we hide it as a part of `handle_post_narrow_deactivate_processes`.
To accomplish this we need to add `has_found_oldest` key to the
`fetch_status` API.
We also removed the `pre_scroll_cont` parameter as this was it's
only use case and is now redundant.
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.

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

Like the other similar commits, we were doing the same work in all
code paths, just with a much more error-prone approach.
We can also now remove the now-unused finish_initial_narrow function.
Like the other commits in this series, we were already doing this in
all of the callers of load_messages; this centralizes that logic in a
less ad-hoc feeling way.
We no longer use or need the start_initial_narrow function.
Previously, each individual caller of load_messages that passed
num_before > 0 would do its own manual management of fetch_status;
now, we just do it inside load_messages.
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
This reverts commit bcdd12773e.
We need to do some improvements in handling FetchStatus for initial
narrows before this will be safe to deploy in production.
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.
