When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.

To make search more efficient, users don't need to move the actual
keyboard focus away from the search entry to activate the first
result. However the shift+f10 shortcut to pop up the context menu
via keyboard still acts on the actually focused widget, which is
the entry. It makes more sense to open the context menu of the
selected result instead, as that's what's highlighted and responds
to keyboard activation.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

Having descriptions with multiple lines will clutter
the view and make it more confusing for the user. Apart
from that, it also makes the search result a lot bigger,
potentially losing general vertical alignment.

The classes extending the SearchResult can now connect
to the 'terms-changed' signal emitted by the SearchResult
class. This signal enables each object to update its
internal description in order to apply the bold style
onto strings that match the search terms.
https://bugzilla.gnome.org/show_bug.cgi?id=749957
In order to prepare for applying the bold style to the part
of the description that matches the search terms, we need
to listen for the signal that announces the fact that the
search terms have changed. Given the fact that the
SearchResults class is aware of the changes regarding the
search terms, the classes that extent SearchResult need
to have a reference to it in order to listen for the
to-be-implemented 'terms-changed' signal.

Since results are now much more concise and take up less
space, we can use the 'saved' space to provide the user
with more search results for each provider.
https://bugzilla.gnome.org/show_bug.cgi?id=749957
The current separator uses a gradient effect as a separator
between search results. As the mockups suggest, the gradient
separator is no longer needed, in favor of a more simple one,
which is a thin semitransparent line.

In order to match the current mockups, the providerIcon
class needed to include both the name of the provider
and the label that informs the user about how many more
search results are available for that specific provider.
The latter replaces the plus sign icon that has been
used so far.

In order to make gnome-shell search functionality fit on
smaller screens, like those of devices, search results
need to take advantage of more horizontal space so that
any extra space can be used efficiently.
In order to do so, change the layout of the ListSearchResult
class from a vertical one, to a horizontal one and also
decrease the padding of the list-search-result-content css
class.

Some search providers such as GNOME Characters want to copy search
results to clipboard. However, on Wayland, clipboards are only
accessible from applications that have a visible surface on display.
This patch allows a search provider to request the shell to copy a
search result to clipboard when 'clipboardText' is included in the meta
of the result.

In recent glib, change notifications don't actually happen unless all
keys have been read, in an effort to reduce unnecessary dbus
traffic for shortlived GSettings object and avoid AddMatch calls.
But we care about changes here, so we need to make sure we're
subscribed, and an easy way to do so is to reuse the same object
to watch for changes and to load the active providers at startup.

When introducing support for "default disabled" search providers
this part was overlooked, so enabling a default disabled provider
would be ignored until the next login.
https://bugzilla.gnome.org/show_bug.cgi?id=746509
We check for (metasNeeded.length == 0) at the beginning of the function,
which is only ever called when when a non-zero number of results is
received back from the provider. Effectively, this means that
(metas.length != metasNeeded.length) will also catch (metas.length == 0)
and print a nicer message to the log.
The updateSearch() function is called in SearchResults every time new
search hits are available from a search provider; SearchResults will
wait for updateSearch() to complete in a callaback, to update the
overall progress of the search operation.
updateSearch() will call _ensureResultActors(), which will in turn call
getResultMetas() on the search provider, which is an operation that can
fail arbitrarily or return inconsistent data, as it's entirely in the
hands of the search provider.
In case _ensureResultActors() returns a failure, updateSearch() is
currently failing to notify the passed-in callback, which might leave
SearchResults in an inconsistent state: make sure the asynchronous flow
always ends up with a notification to the updateSearch() callback.
Checks for a duplicate search before setting the current search
to true and before cancelling the current search. This ensures that
if a duplicate search occurs while the previous search is still active,
the duplicate search will not incorrectly cancel or change the state
of the previous search.
When the overview is created, search is populated with one actor for
each provider. As they're not hidden though, they will contribute to the
overall size request of the search page, which will shift upwards the
overview grid.

This lets us considerably clean up the event flow here and change how
things are structured. It also makes sure that we never show "No
Results" -- search.js not being aware of the timeout means that it might
not think that any work was being done when we show the page.
Keep a flag depending on whether a provider is in-flight, and use that
to determine what status label to show.
This ensures that we only show "No Results" when we're done searching
and we're sure that all providers have returned results back to us.
The complexities of tracking these two things separately, with the
display on one half, and the searching on the other half, is difficult
to manage. Squash it all together.
Providers that need drag-and-drop behavior can implement this via the
createResultObject() hook (as the app search provider already does), no
need to duplicate that code in the generic result objects
(ListSearchResult already does not implement DND).

The existing code broke when commit 792b963bda changed the custom
result actor hook to return an object instead of an actor - stop
trying to go through a _delegate to make it work again.
Search providers that should be disabled by default come with
a DefaultDisabled=true key in their keyfile, and are enabled

Currently to know how many results we could show for GridResults
we use the width of the bin containing those results. Since it's
expanding it shouldn't be a problem. But it becomes a problem when
no results are displayed, thus the container becomes hidden and
it losts its allocation.
In the next introduction of terms in search we call again
maxDisplayedResults but it doesn't have allocation yet, and therefore no
results are displayed (currently a bug on IconGrid makes the min size =
one icon, so actually we show one and only one icon in this case).
To solve that use the parent container which contains the search results
of all providers or the text label with not displayed results, so it
always have the real available width to calculate maxDisplayedResults.
Thanks Alban Browaeys for the debugging footwork.

When we unregistered providers, like when we refreshed the list of
active remote providers, we would forget to destroy the old provider
display after the fact. This left an empty "skeleton" provider display
still in the search results that would never be filled in. Make sure
to destroy it properly.
https://bugzilla.gnome.org/show_bug.cgi?id=728597
We can't let live (ie, never destroyed) actors undergo GC, because
they will emit :destroy signals during finalization and assert/crash
libmozjs. Properly destroy all actors before letting the GC
free them.

There's a potential race condition in the search code: if we have an
outstanding search call to a provider for search "A", and if before it comes
back we do a subsearch for "AB", we won't have any results to pass along.
Previously, we used an empty list when storing the provider results, so we
effectively told the remote search app to filter through this empty list for
any search results that meet the new query, meaning we showed the user 0
results for the provider in this case.
Now that we don't store an empty list, but instead store `undefined`, this race
raises a warning. Solve it by doing an initial search query in this case
instead.
The search code isn't too smart about chained subsearches: now, if we hit this
race while already on a subsearch, we'll do an initial search for the subsearch
query instead, but that is much better than showing the user nothing. This
could be fixed in the future for a performance improvement.

Long ago, the search system worked in a synchronous manner: providers
were given a query, and results were collected in a single array of
[provider, results] pairs, and then the search display was updated
from that.
We introduced an asynchronous search system when we wanted to potentially
add a Zeitgeist search provider to the Shell in 3.2. For a while, search
providers were either async or sync, which worked by storing a dummy array
in the results, and adding a method for search providers to add results
later.
Later, we removed the search system entirely and ported the remaining
search providers to simply use the API to modify the empty array, but the
remains of the synchronous search system with its silly array still
lingered.
Finally, it's time to modernize. Promises^WCallbacks are the future.
Port the one remaining in-shell search engine (app search) to the new
callback based system, and simplify the remote search system in the
process.
When we create a result actor, cache it, so it can be used for
subsearches of the same initial. For now, to keep memory usage
and the stage graph relatively clean, don't persist the actors
across searches, but maybe we should do this in the future.
This also means that we don't query getResultMetas for items
that we've seen in the same initial search.

The existing provider system is split between a confusing mess of
RemoteSearch, SearchSystem, SearchDisplay, and ViewSelector, partly
because of the vestigal in-shell search system. Move most of the
logic to search.js so it's easier to read.
We fetch and store the list of providers from the search system when we
construct SearchResults, but we never update this list when providers are
changed at runtime, causing various bugs making the search not seem as
snappy as it should be. Make sure to always fetch the list of providers
from the search system.
search.js used to do a lot more, but now that most of the
functionality has been moved to the remote search system,
it doesn't do a lot. Merge searchDisplay.js into it.
When we reload the remote search providers, we currently try to remove
all remote providers, and then re-scan. It turns out that we sometimes
remove the wrong providers from the remote provider list, causing us to
have some providers not correctly unloaded.

pushResults, and the original async search API, were originally intended
so search results that weren't immediate could be added as they come in.
Since then, we've decided that the design of search results is that they
should finish at once with all results. Thus, the code was modified so
that pushResults always overwrote the current result set. As such, it makes
sense to rename the method so that the name matches the behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=693836
Early on, search was based on a list of terms, which was like a set
of tags, in that terms were OR'd, and that order didn't matter. As
such, modifying any one of the terms wouldn't produce new results.
Nowadays, providers take the order into account, so a substring
should only be the case if new terms are added to the end.

These are for all search results except apps (and Wanda).
We also simplify a bit the packing of search results, which removes some

The original design for the overview had buttons for searching for

As shown in the previous commits, synchronous search is easily implemented
by the asynchronous search API. The only reason we still have a

To allow this to happen, we need to make sure that we don't overwrite the
previousResults when calling the async method. Note that this is a bug of

We will allow applications to hook into shell's search by registering
a service which implements a well-known DBus interface.
"search-providers" is a reasonable directory name for applications to
drop their registration files, but it conflicts with "search_providers"
used by open search providers - rename the latter to avoid confusion.
https://bugzilla.gnome.org/show_bug.cgi?id=663125
Currently, asynchronous search providers are expected to call
startAsync() in getInitialResultSet()/getSubsearchResultSet(),
which will trigger async mode until the search is canceled or
updated. Switching between synchronous and asynchronous mode like
this makes asynchronous search an implementation detail, but being
transparent to the searchDisplay means that certain optimizations
don't work as expected. Namely, updating asynchronous search results
causes flickering, and the automatic selection never focuses
asynchronous results.
So change the API to require providers being either synchronous (with
the current getInitialResultSet()/getSubsearchResultSet() methods)
or asynchronous (with asynchronous variants), and handle asynchronous
providers explicitly in searchDisplay.
