-// each time the menu is shown (e.g. AppMenuModel, TabContextMenuContents,
-// etc.) The case where the delegate object is persistent will be discussed
-// later.
-//
-//   // Menu model constructor:
-//   MyMenuModelDelegate::MyMenuModelDelegate(Browser* browser, ...) : ...
-//       new_badge_tracker_(browser->profile()),
-//
-//   // In OnMenuWillShow(menu):
-//   menu->SetIsNewFeatureAt(
-//       menu->GetIndexOfCommandId(IDC_MY_FEATURE),
-//       new_badge_tracker_.TryShowNewBadge(
-//           feature_engagement::kIPHMyFeatureNewBadge,
-//           &ui_features::kMyFeature));
-//
-//   // In ExecuteCommand():
-//   case IDC_MY_FEATURE:
-//     new_badge_tracker_.EventPerformed("my_feature_activated");
-//     ...
-//     break;
-//
-// If the New Badge is in the top-level menu, you can move the call to
-// SetIsNewFeatureAt() to immediately after the menu model is initialized
-// (typically in the constructor or "Init" method) and you will not have to
-// override OnMenuWillBeShown().
-//
-// If you are handling multiple New Badges for different features, you will
-// want to check the result of GetIndexOfCommand() to make sure the menu being
-// shown is the one that contains the item receiving the new badge.
-//
-// If the ui::SimpleMenuModel::Delegate is a persistent object and is not
-// created each time the menu is displayed, you will need to move the tracker
-// down into the ui::SimpleMenuModel for your menu, and move your code from
-// OnMenuWillShow() to MenuWillShow() and from ExecuteCommand() to
-// ActivatedAt(int, int). Be sure to invoke base class behavior when overriding
-// these methods!
-//
-// * Dialogs
-//
-// Add a ScopedNewBadgeTracker member variable to your DialogDelegateView.
-// Dialogs are typically not re-usable; we create a new DialogDelegateView for
-// each time we show them. If you are following this pattern, include this in
-// your constructor or "Init" function after creating the NewBadgeLabel (but
-// before showing the dialog):
-//
-//   new_badge_label_->SetDisplayNewBadge(
-//       new_badge_tracker_.TryShowNewBadge(
-//           feature_engagement::kIPHMyFeatureNewBadge,
-//           &ui_features::kMyFeature));
-//
-// Then in the callback for the button that activates the feature being
-// promoted, call:
-//
-//   new_badge_tracker_.EventPerformed("my_feature_activated");
-//
-// If for some reason you are re-using a dialog delegate, you must dynamically
-// create and destroy the tracker when the dialog is shown and hidden.

+// Works with the Feature Engagement system to determine when/how many times a
+// New Badge is displayed to the user. Wraps a feature_engagement::Tracker so
+// the correct calls are made to the Feature Engagement backend.
+//
+// Derive a subclass for a more convenient constructor (e.g. one that takes a
+// Browser or Profile rather than a raw feature_engagement::Tracker).
+//
+// The lifespan of a ScopedNewBadgeTracker should match the time the dialog or
+// menu containing the New Badge is visible to the user.
+//
+// You may use a single tracker for New Badges on multiple features in the same
+// menu or dialog, but make sure the feature flags and event names are distinct.
+//
+// Usage:
+//
+// * Menus
+//
+// Below is an example of using a ScopedNewBadgeTracker to add a New Badge to a
+// menu where the object implementing ui::SimpleMenuModel::Delegate is created
+// each time the menu is shown (e.g. AppMenuModel, TabContextMenuContents,
+// etc.) The case where the delegate object is persistent will be discussed
+// later.
+//
+//   // In OnMenuWillShow(menu):
+//   menu->SetIsNewFeatureAt(
+//       menu->GetIndexOfCommandId(IDC_MY_FEATURE),
+//       new_badge_tracker_.TryShowNewBadge(
+//           feature_engagement::kIPHMyFeatureNewBadge,
+//           &ui_features::kMyFeature));
+//
+//   // In ExecuteCommand():
+//   case IDC_MY_FEATURE:
+//     new_badge_tracker_.EventPerformed("my_feature_activated");
+//     ...
+//     break;
+//
+// If the New Badge is in the top-level menu, you can move the call to
+// SetIsNewFeatureAt() to immediately after the menu model is initialized
+// (typically in the constructor or "Init" method) and you will not have to
+// override OnMenuWillBeShown().
+//
+// If you are handling multiple New Badges for different features, you will
+// want to check the result of GetIndexOfCommand() to make sure the menu being
+// shown is the one that contains the item receiving the new badge.
+//
+// If the ui::SimpleMenuModel::Delegate is a persistent object and is not
+// created each time the menu is displayed, you will need to move the tracker
+// down into the ui::SimpleMenuModel for your menu, and move your code from
+// OnMenuWillShow() to MenuWillShow() and from ExecuteCommand() to
+// ActivatedAt(int, int). Be sure to invoke base class behavior when overriding
+// these methods!
+//
+// * Dialogs
+//
+// Add a ScopedNewBadgeTracker member variable to your DialogDelegateView.
+// Dialogs are typically not re-usable; we create a new DialogDelegateView for
+// each time we show them. If you are following this pattern, include this in
+// your constructor or "Init" function after creating the NewBadgeLabel (but
+// before showing the dialog):
+//
+//   new_badge_label_->SetDisplayNewBadge(
+//       new_badge_tracker_.TryShowNewBadge(
+//           feature_engagement::kIPHMyFeatureNewBadge,
+//           &ui_features::kMyFeature));
+//
+// Then in the callback for the button that activates the feature being
+// promoted, call:
+//
+//   new_badge_tracker_.EventPerformed("my_feature_activated");
+//
+// If for some reason you are re-using a dialog delegate, you must dynamically
+// create and destroy the tracker when the dialog is shown and hidden.

+/**
+ * Overview:
+ *
+ * This module is designed to add support for an async `setValue` API and
+ * `disconnected` callback to directives with the least impact on the core
+ * runtime or payload when that feature is not used.
+ *
+ * The strategy is to introduce a `AsyncDirective` subclass of
+ * `Directive` that climbs the "parent" tree in its constructor to note which
+ * branches of lit-html's "logical tree" of data structures contain such
+ * directives and thus need to be crawled when a subtree is being cleared (or
+ * manually disconnected) in order to run the `disconnected` callback.
+ *
+ * The "nodes" of the logical tree include Parts, TemplateInstances (for when a
+ * TemplateResult is committed to a value of a ChildPart), and Directives; these
+ * all implement a common interface called `DisconnectableChild`. Each has a
+ * `_$parent` reference which is set during construction in the core code, and a
+ * `_$disconnectableChildren` field which is initially undefined.
+ *
+ * The sparse tree created by means of the `AsyncDirective` constructor
+ * crawling up the `_$parent` tree and placing a `_$disconnectableChildren` Set
+ * on each parent that includes each child that contains a
+ * `AsyncDirective` directly or transitively via its children. In order to
+ * notify connection state changes and disconnect (or reconnect) a tree, the
+ * `_$notifyConnectionChanged` API is patched onto ChildParts as a directive
+ * climbs the parent tree, which is called by the core when clearing a part if
+ * it exists. When called, that method iterates over the sparse tree of
+ * Set<DisconnectableChildren> built up by AsyncDirectives, and calls
+ * `_$notifyDirectiveConnectionChanged` on any directives that are encountered
+ * in that tree, running the required callbacks.
+ *
+ * A given "logical tree" of lit-html data-structures might look like this:
+ *
+ *  ChildPart(N1) _$dC=[D2,T3]
+ *   ._directive
+ *     AsyncDirective(D2)
+ *   ._value // user value was TemplateResult
+ *     TemplateInstance(T3) _$dC=[A4,A6,N10,N12]
+ *      ._parts[]
+ *        AttributePart(A4) _$dC=[D5]
+ *         ._directives[]
+ *           AsyncDirective(D5)
+ *        AttributePart(A6) _$dC=[D7,D8]
+ *         ._directives[]
+ *           AsyncDirective(D7)
+ *           Directive(D8) _$dC=[D9]
+ *            ._directive
+ *              AsyncDirective(D9)
+ *        ChildPart(N10) _$dC=[D11]
+ *         ._directive
+ *           AsyncDirective(D11)
+ *         ._value
+ *           string
+ *        ChildPart(N12) _$dC=[D13,N14,N16]
+ *         ._directive
+ *           AsyncDirective(D13)
+ *         ._value // user value was iterable
+ *           Array<ChildPart>
+ *             ChildPart(N14) _$dC=[D15]
+ *              ._value
+ *                string
+ *             ChildPart(N16) _$dC=[D17,T18]
+ *              ._directive
+ *                AsyncDirective(D17)
+ *              ._value // user value was TemplateResult
+ *                TemplateInstance(T18) _$dC=[A19,A21,N25]
+ *                 ._parts[]
+ *                   AttributePart(A19) _$dC=[D20]
+ *                    ._directives[]
+ *                      AsyncDirective(D20)
+ *                   AttributePart(A21) _$dC=[22,23]
+ *                    ._directives[]
+ *                      AsyncDirective(D22)
+ *                      Directive(D23) _$dC=[D24]
+ *                       ._directive
+ *                         AsyncDirective(D24)
+ *                   ChildPart(N25) _$dC=[D26]
+ *                    ._directive
+ *                      AsyncDirective(D26)
+ *                    ._value
+ *                      string
+ *
+ * Example 1: The directive in ChildPart(N12) updates and returns `nothing`. The
+ * ChildPart will _clear() itself, and so we need to disconnect the "value" of
+ * the ChildPart (but not its directive). In this case, when `_clear()` calls
+ * `_$notifyConnectionChanged()`, we don't iterate all of the
+ * _$disconnectableChildren, rather we do a value-specific disconnection: i.e.
+ * since the _value was an Array<ChildPart> (because an iterable had been
+ * committed), we iterate the array of ChildParts (N14, N16) and run
+ * `setConnected` on them (which does recurse down the full tree of
+ * `_$disconnectableChildren` below it, and also removes N14 and N16 from N12's
+ * `_$disconnectableChildren`). Once the values have been disconnected, we then
+ * check whether the ChildPart(N12)'s list of `_$disconnectableChildren` is empty
+ * (and would remove it from its parent TemplateInstance(T3) if so), but since
+ * it would still contain its directive D13, it stays in the disconnectable
+ * tree.
+ *
+ * Example 2: In the course of Example 1, `setConnected` will reach
+ * ChildPart(N16); in this case the entire part is being disconnected, so we
+ * simply iterate all of N16's `_$disconnectableChildren` (D17,T18) and
+ * recursively run `setConnected` on them. Note that we only remove children
+ * from `_$disconnectableChildren` for the top-level values being disconnected
+ * on a clear; doing this bookkeeping lower in the tree is wasteful since it's
+ * all being thrown away.
+ *
+ * Example 3: If the LitElement containing the entire tree above becomes
+ * disconnected, it will run `childPart.setConnected()` (which calls
+ * `childPart._$notifyConnectionChanged()` if it exists); in this case, we
+ * recursively run `setConnected()` over the entire tree, without removing any
+ * children from `_$disconnectableChildren`, since this tree is required to
+ * re-connect the tree, which does the same operation, simply passing
+ * `isConnected: true` down the tree, signaling which callback to run.

-        //   case and removals would be handled in the final while loop
-        //   without needing to generate the map.
-        //
-        // * Example below: The key at `oldTail` was removed (no longer
-        //   in the `newKeyToIndexMap`), so remove that part from the
-        //   DOM and advance just the `oldTail` pointer.

-        //         newHead ^           ^ newTail
-        //
-        // * Once head and tail cannot move, any mismatches are due to
-        //   either new or moved items; if a new key is in the previous
-        //   "old key to old index" map, move the old part to the new
-        //   location, otherwise create and insert a new part. Note
-        //   that when moving an old part we null its position in the
-        //   oldParts array if it lies between the head and tail so we
-        //   know to skip it when the pointers get there.
-        //
-        // * Example below: neither head nor tail match, and neither
-        //   were removed; so find the `newHead` key in the
-        //   `oldKeyToIndexMap`, and move that old part's DOM into the
-        //   next head position (before `oldParts[oldHead]`). Last,
-        //   null the part in the `oldPart` array since it was
-        //   somewhere in the remaining oldParts still to be scanned
-        //   (between the head and tail pointers) so that we know to
-        //   skip that old part on future iterations.
-        //
-        //         oldHead v        v oldTail

-        //         newHead ^           ^ newTail
-        //
-        // * Note that for moves/insertions like the one above, a part
-        //   inserted at the head pointer is inserted before the
-        //   current `oldParts[oldHead]`, and a part inserted at the
-        //   tail pointer is inserted before `newParts[newTail+1]`. The
-        //   seeming asymmetry lies in the fact that new parts are
-        //   moved into place outside in, so to the right of the head
-        //   pointer are old parts, and to the right of the tail
-        //   pointer are new parts.
-        //
-        // * We always restart back from the top of the algorithm,
-        //   allowing matching and simple updates in place to
-        //   continue...
-        //
-        // * Example below: the head pointers once again match, so
-        //   simply update part 1 and record it in the `newParts`
-        //   array.  Last, advance both head pointers.
-        //
-        //         oldHead v        v oldTail

-        //            newHead ^        ^ newTail
-        //
-        // * As mentioned above, items that were moved as a result of
-        //   being stuck (the final else clause in the code below) are
-        //   marked with null, so we always advance old pointers over
-        //   these so we're comparing the next actual old value on
-        //   either end.
-        //
-        // * Example below: `oldHead` is null (already placed in
-        //   newParts), so advance `oldHead`.
-        //
-        //            oldHead v     v oldTail

-        //               newHead ^     ^ newTail
-        //
-        // * Note it's not critical to mark old parts as null when they
-        //   are moved from head to tail or tail to head, since they
-        //   will be outside the pointer range and never visited again.
-        //
-        // * Example below: Here the old tail key matches the new head
-        //   key, so the part at the `oldTail` position and move its
-        //   DOM to the new head position (before `oldParts[oldHead]`).

- * and ShadyCSS (https://github.com/webcomponents/shadycss) polyfills are used
- * or when the webcomponentsjs
- * (https://github.com/webcomponents/webcomponentsjs) polyfill is used.
- *
- * Adds a `scopeName` option which is used to scope element DOM and stylesheets
- * when native ShadowDOM is unavailable. The `scopeName` will be added to
- * the class attribute of all rendered DOM. In addition, any style elements will
- * be automatically re-written with this `scopeName` selector and moved out
- * of the rendered DOM and into the document `<head>`.
- *
- * It is common to use this render method in conjunction with a custom element
- * which renders a shadowRoot. When this is done, typically the element's
- * `localName` should be used as the `scopeName`.
- *
- * In addition to DOM scoping, ShadyCSS also supports a basic shim for css
- * custom properties (needed only on older browsers like IE11) and a shim for
- * a deprecated feature called `@apply` that supports applying a set of css
- * custom properties to a given location.
- *
- * Usage considerations:
- *
- * * Part values in `<style>` elements are only applied the first time a given
- * `scopeName` renders. Subsequent changes to parts in style elements will have
- * no effect. Because of this, parts in style elements should only be used for
- * values that will never change, for example parts that set scope-wide theme
- * values or parts which render shared style elements.
- *
- * * Note, due to a limitation of the ShadyDOM polyfill, rendering in a
- * custom element's `constructor` is not supported. Instead rendering should
- * either done asynchronously, for example at microtask timing (for example
- * `Promise.resolve()`), or be deferred until the first time the element's
- * `connectedCallback` runs.
- *
- * Usage considerations when using shimmed custom properties or `@apply`:
- *
- * * Whenever any dynamic changes are made which affect
- * css custom properties, `ShadyCSS.styleElement(element)` must be called
- * to update the element. There are two cases when this is needed:
- * (1) the element is connected to a new parent, (2) a class is added to the
- * element that causes it to match different custom properties.
- * To address the first case when rendering a custom element, `styleElement`
- * should be called in the element's `connectedCallback`.
- *
- * * Shimmed custom properties may only be defined either for an entire
- * shadowRoot (for example, in a `:host` rule) or via a rule that directly
- * matches an element with a shadowRoot. In other words, instead of flowing from
- * parent to child as do native css custom properties, shimmed custom properties
- * flow only from shadowRoots to nested shadowRoots.
- *
- * * When using `@apply` mixing css shorthand property names with
- * non-shorthand names (for example `border` and `border-width`) is not
- * supported.

- * custom properties (needed only on older browsers like IE11) and a shim for
- * a deprecated feature called `@apply` that supports applying a set of css
- * custom properties to a given location.
- *
- * Usage considerations:
- *
- * * Part values in `<style>` elements are only applied the first time a given
- * `scopeName` renders. Subsequent changes to parts in style elements will have
- * no effect. Because of this, parts in style elements should only be used for
- * values that will never change, for example parts that set scope-wide theme
- * values or parts which render shared style elements.
- *
- * * Note, due to a limitation of the ShadyDOM polyfill, rendering in a
- * custom element's `constructor` is not supported. Instead rendering should
- * either done asynchronously, for example at microtask timing (for example
- * `Promise.resolve()`), or be deferred until the first time the element's
- * `connectedCallback` runs.
- *
- * Usage considerations when using shimmed custom properties or `@apply`:
- *
- * * Whenever any dynamic changes are made which affect
- * css custom properties, `ShadyCSS.styleElement(element)` must be called
- * to update the element. There are two cases when this is needed:
- * (1) the element is connected to a new parent, (2) a class is added to the
- * element that causes it to match different custom properties.
- * To address the first case when rendering a custom element, `styleElement`
- * should be called in the element's `connectedCallback`.
- *
- * * Shimmed custom properties may only be defined either for an entire
- * shadowRoot (for example, in a `:host` rule) or via a rule that directly
- * matches an element with a shadowRoot. In other words, instead of flowing from
- * parent to child as do native css custom properties, shimmed custom properties
- * flow only from shadowRoots to nested shadowRoots.
- *
- * * When using `@apply` mixing css shorthand property names with
- * non-shorthand names (for example `border` and `border-width`) is not
- * supported.

- * Here's an example of using the `repeat()` directive factory that takes an

- * array and a function to render an item:

- *

- * ```js

- * html`<ul><${repeat(items, (item) => html`<li>${item}</li>`)}</ul>`

- * ```

- *

- * When `repeat` is invoked, it returns a directive function that closes over

- * `items` and the template function. When the outer template is rendered, the

- * return directive function is called with the Part for the expression.

- * `repeat` then performs it's custom logic to render multiple items.

- *

- * @param f The directive factory function. Must be a function that returns a

- * function of the signature `(part: Part) => void`. The returned function will

- * be called with the part object.

- *

- * @example

- *

- * import {directive, html} from 'lit-html';

- *

- * const immutable = directive((v) => (part) => {

- *   if (part.value !== v) {

- *     part.setValue(v)

- *   }

- * });

- * and ShadyCSS (https://github.com/webcomponents/shadycss) polyfills are used

- * or when the webcomponentsjs

- * (https://github.com/webcomponents/webcomponentsjs) polyfill is used.

- *

- * Adds a `scopeName` option which is used to scope element DOM and stylesheets

- * when native ShadowDOM is unavailable. The `scopeName` will be added to

- * the class attribute of all rendered DOM. In addition, any style elements will

- * be automatically re-written with this `scopeName` selector and moved out

- * of the rendered DOM and into the document `<head>`.

- *

- * It is common to use this render method in conjunction with a custom element

- * which renders a shadowRoot. When this is done, typically the element's

- * `localName` should be used as the `scopeName`.

- *

- * In addition to DOM scoping, ShadyCSS also supports a basic shim for css

- * custom properties (needed only on older browsers like IE11) and a shim for

- * a deprecated feature called `@apply` that supports applying a set of css

- * custom properties to a given location.

- *

- * Usage considerations:

- *

- * * Part values in `<style>` elements are only applied the first time a given

- * `scopeName` renders. Subsequent changes to parts in style elements will have

- * no effect. Because of this, parts in style elements should only be used for

- * values that will never change, for example parts that set scope-wide theme

- * values or parts which render shared style elements.

- *

- * * Note, due to a limitation of the ShadyDOM polyfill, rendering in a

- * custom element's `constructor` is not supported. Instead rendering should

- * either done asynchronously, for example at microtask timing (for example

- * `Promise.resolve()`), or be deferred until the first time the element's

- * `connectedCallback` runs.

- *

- * Usage considerations when using shimmed custom properties or `@apply`:

- *

- * * Whenever any dynamic changes are made which affect

- * css custom properties, `ShadyCSS.styleElement(element)` must be called

- * to update the element. There are two cases when this is needed:

- * (1) the element is connected to a new parent, (2) a class is added to the

- * element that causes it to match different custom properties.

- * To address the first case when rendering a custom element, `styleElement`

- * should be called in the element's `connectedCallback`.

- *

- * * Shimmed custom properties may only be defined either for an entire

- * shadowRoot (for example, in a `:host` rule) or via a rule that directly

- * matches an element with a shadowRoot. In other words, instead of flowing from

- * parent to child as do native css custom properties, shimmed custom properties

- * flow only from shadowRoots to nested shadowRoots.

- *

- * * When using `@apply` mixing css shorthand property names with

- * non-shorthand names (for example `border` and `border-width`) is not

- * supported.
