// another nightly release which disables seccomp-bpf again.

/**
 * Session Storage and Restoration
 *
 * Overview
 * This service reads user's session file at startup, and makes a determination
 * as to whether the session should be restored. It will restore the session
 * under the circumstances described below.  If the auto-start Private Browsing
 * mode is active, however, the session is never restored.
 *
 * Crash Detection
 * The CrashMonitor is used to check if the final session state was successfully
 * written at shutdown of the last session. If we did not reach
 * 'sessionstore-final-state-write-complete', then it's assumed that the browser
 * has previously crashed and we should restore the session.
 *
 * Forced Restarts
 * In the event that a restart is required due to application update or extension
 * installation, set the browser.sessionstore.resume_session_once pref to true,
 * and the session will be restored the next time the browser starts.
 *
 * Always Resume
 * This service will always resume the session if the integer pref
 * browser.startup.page is set to 3.

/**
 * Allows a popup panel to host multiple subviews. The main view shown when the
 * panel is opened may slide out to display a subview, which in turn may lead to
 * other subviews in a cascade menu pattern.
 *
 * The <panel> element should contain a <panelmultiview> element. Views are
 * declared using <panelview> elements that are usually children of the main
 * <panelmultiview> element, although they don't need to be, as views can also
 * be imported into the panel from other panels or popup sets.
 *
 * The panel should be opened asynchronously using the openPopup static method
 * on the PanelMultiView object. This will display the view specified using the
 * mainViewId attribute on the contained <panelmultiview> element.
 *
 * Specific subviews can slide in using the showSubView method, and backwards
 * navigation can be done using the goBack method or through a button in the
 * subview headers.
 *
 * The process of displaying the main view or a new subview requires multiple
 * steps to be completed, hence at any given time the <panelview> element may
 * be in different states:
 *
 * -- Open or closed
 *
 *    All the <panelview> elements start "closed", meaning that they are not
 *    associated to a <panelmultiview> element and can be located anywhere in
 *    the document. When the openPopup or showSubView methods are called, the
 *    relevant view becomes "open" and the <panelview> element may be moved to
 *    ensure it is a descendant of the <panelmultiview> element.
 *
 *    The "ViewShowing" event is fired at this point, when the view is not
 *    visible yet. The event is allowed to cancel the operation, in which case
 *    the view is closed immediately.
 *
 *    Closing the view does not move the node back to its original position.
 *
 * -- Visible or invisible
 *
 *    This indicates whether the view is visible in the document from a layout
 *    perspective, regardless of whether it is currently scrolled into view. In
 *    fact, all subviews are already visible before they start sliding in.
 *
 *    Before scrolling into view, a view may become visible but be placed in a
 *    special off-screen area of the document where layout and measurements can
 *    take place asyncronously.
 *
 *    When navigating forward, an open view may become invisible but stay open
 *    after sliding out of view. The last known size of these views is still
 *    taken into account for determining the overall panel size.
 *
 *    When navigating backwards, an open subview will first become invisible and
 *    then will be closed.
 *
 * -- Active or inactive
 *
 *    This indicates whether the view is fully scrolled into the visible area
 *    and ready to receive mouse and keyboard events. An active view is always
 *    visible, but a visible view may be inactive. For example, during a scroll
 *    transition, both views will be inactive.
 *
 *    When a view becomes active, the ViewShown event is fired synchronously,
 *    and the showSubView and goBack methods can be called for navigation.
 *
 *    For the main view of the panel, the ViewShown event is dispatched during
 *    the "popupshown" event, which means that other "popupshown" handlers may
 *    be called before the view is active. Thus, code that needs to perform
 *    further navigation automatically should either use the ViewShown event or
 *    wait for an event loop tick, like BrowserTestUtils.waitForEvent does.
 *
 * -- Navigating with the keyboard
 *
 *    An open view may keep state related to keyboard navigation, even if it is
 *    invisible. When a view is closed, keyboard navigation state is cleared.
 *
 * This diagram shows how <panelview> nodes move during navigation:
 *

 * Creates a new object that manages search suggestions and their UI for a text

 *
 * The UI consists of an html:table that's inserted into the DOM after the given

 *
 * @param inputElement
 *        Search suggestions will be based on the text in this text box.
 *        Assumed to be an html:input.  xul:textbox is untested but might work.
 * @param tableParent
 *        The suggestion table is appended as a child to this element.  Since
 *        the table is absolutely positioned and its top and left values are set
 *        to be relative to the top and left of the page, either the parent and
 *        all its ancestors should not be positioned elements (i.e., their
 *        positions should be "static"), or the parent's position should be the
 *        top left of the page.
 * @param healthReportKey
 *        This will be sent with the search data for FHR to record the search.
 * @param searchPurpose
 *        Sent with search data, see nsISearchEngine.getSubmission.
 * @param idPrefix
 *        The IDs of elements created by the object will be prefixed with this

   *       c: 0

   * and again.
   *
   * @param aKeys the Array of keys to chain Objects together with.
   * @param aEndWith the value to assign to the last key.
   * @param aRoot the root object onto which we create/get the object chain

  *                    * __DEFAULT__ - until a new bucket is set
  * @param aTimeOffset Time offset, in milliseconds, from which to start
  *                    counting. For example, if the first time step is 1000ms,
  *                    and the time offset is 300ms, then the next time step
  *                    will become active after 700ms. This affects all

    // different data types, e.g. news/blogs (traditional feed), video/audio
    // (podcasts) and photos (photocasts, photostreams). Each of these is
    // different in that there's a different class of application suitable for
    // handling feeds of that type, but without a content-type differentiation
    // it is difficult for us to disambiguate.
    //
    // The other problem is that if the user specifies an auto-action handler
    // for one feed application, the fact that the content type is shared means
    // that all other applications will auto-load with that handler too,
    // regardless of the content-type.
    //
    // This means that content-type alone is not enough to determine whether
    // or not a feed should be auto-handled. This means that for feeds we need
    // to always use this stream converter, even when an auto-action is
    // specified, not the basic one provided by WebContentConverter. This
    // converter needs to consume all of the data and parse it, and based on
    // that determination make a judgment about type.
    //
    // Since there are no content types for this content, and I'm not going to
    // invent any, the upshot is that while a user can set an auto-handler for
    // generic feed content, the system will prevent them from setting an auto-
    // handler for other stream types. In those cases, the user will always see
    // the preview page and have to select a handler. We can guess and show
    // a client handler, but will not be able to show web handlers for those
    // types.

 * A service that allows for the overriding, at runtime, of the newtab page's url.
 *
 * There is tight coupling with browser/about/AboutRedirector.cpp.
 *
 * 1. Browser chrome access:
 *
 * When the user issues a command to open a new tab page, usually clicking a button
 * in the browser chrome or using shortcut keys, the browser chrome code invokes the
 * service to obtain the newtab URL. It then loads that URL in a new tab.
 *
 * When not overridden, the default URL emitted by the service is "about:newtab".
 * When overridden, it returns the overriden URL.
 *
 * 2. Redirector Access:
 *
 * When the URL loaded is about:newtab, the default behavior, or when entered in the
 * URL bar, the redirector is hit. The service is then called to return the
 * appropriate activity stream url based on prefs and locales.
 *
 * NOTE: "about:newtab" will always result in a default newtab page, and never an overridden URL.
 *
 * Access patterns:
 *
 * The behavior is different when accessing the service via browser chrome or via redirector
 * largely to maintain compatibility with expectations of add-on developers.
 *
 * Loading a chrome resource, or an about: URL in the redirector with either the
 * LOAD_NORMAL or LOAD_REPLACE flags yield unexpected behaviors, so a roundtrip
 * to the redirector from browser chrome is avoided.

/**
 * The tab switcher is responsible for asynchronously switching
 * tabs in e10s. It waits until the new tab is ready (i.e., the
 * layer tree is available) before switching to it. Then it
 * unloads the layer tree for the old tab.
 *
 * The tab switcher is a state machine. For each tab, it
 * maintains state about whether the layer tree for the tab is
 * available, being loaded, being unloaded, or unavailable. It
 * also keeps track of the tab currently being displayed, the tab
 * it's trying to load, and the tab the user has asked to switch
 * to. The switcher object is created upon tab switch. It is
 * released when there are no pending tabs to load or unload.
 *
 * The following general principles have guided the design:
 *
 * 1. We only request one layer tree at a time. If the user
 * switches to a different tab while waiting, we don't request
 * the new layer tree until the old tab has loaded or timed out.
 *
 * 2. If loading the layers for a tab times out, we show the
 * spinner and possibly request the layer tree for another tab if
 * the user has requested one.
 *
 * 3. We discard layer trees on a delay. This way, if the user is
 * switching among the same tabs frequently, we don't continually
 * load the same tabs.
 *
 * It's important that we always show either the spinner or a tab
 * whose layers are available. Otherwise the compositor will draw
 * an entirely black frame, which is very jarring. To ensure this
 * never happens when switching away from a tab, we assume the
 * old tab might still be drawn until a MozAfterPaint event
 * occurs. Because layout and compositing happen asynchronously,
 * we don't have any other way of knowing when the switch
 * actually takes place. Therefore, we don't unload the old tab
 * until the next MozAfterPaint event.

   * Add a listener object that will get fired for various events regarding
   * customization.
   *
   * @param aListener the listener object to add
   *
   * Not all event handler methods need to be defined.
   * CustomizableUI will catch exceptions. Events are dispatched
   * synchronously on the UI thread, so if you can delay any/some of your
   * processing, that is advisable. The following event handlers are supported:
   *   - onWidgetAdded(aWidgetId, aArea, aPosition)
   *     Fired when a widget is added to an area. aWidgetId is the widget that
   *     was added, aArea the area it was added to, and aPosition the position
   *     in which it was added.
   *   - onWidgetMoved(aWidgetId, aArea, aOldPosition, aNewPosition)
   *     Fired when a widget is moved within its area. aWidgetId is the widget
   *     that was moved, aArea the area it was moved in, aOldPosition its old
   *     position, and aNewPosition its new position.
   *   - onWidgetRemoved(aWidgetId, aArea)
   *     Fired when a widget is removed from its area. aWidgetId is the widget
   *     that was removed, aArea the area it was removed from.
   *
   *   - onWidgetBeforeDOMChange(aNode, aNextNode, aContainer, aIsRemoval)
   *     Fired *before* a widget's DOM node is acted upon by CustomizableUI
   *     (to add, move or remove it). aNode is the DOM node changed, aNextNode
   *     the DOM node (if any) before which a widget will be inserted,
   *     aContainer the *actual* DOM container (could be an overflow panel in
   *     case of an overflowable toolbar), and aWasRemoval is true iff the
   *     action about to happen is the removal of the DOM node.
   *   - onWidgetAfterDOMChange(aNode, aNextNode, aContainer, aWasRemoval)
   *     Like onWidgetBeforeDOMChange, but fired after the change to the DOM
   *     node of the widget.
   *
   *   - onWidgetReset(aNode, aContainer)
   *     Fired after a reset to default placements moves a widget's node to a
   *     different location. aNode is the widget's node, aContainer is the
   *     area it was moved into (NB: it might already have been there and been
   *     moved to a different position!)
   *   - onWidgetUndoMove(aNode, aContainer)
   *     Fired after undoing a reset to default placements moves a widget's
   *     node to a different location. aNode is the widget's node, aContainer
   *     is the area it was moved into (NB: it might already have been there
   *     and been moved to a different position!)
   *   - onAreaReset(aArea, aContainer)
   *     Fired after a reset to default placements is complete on an area's
   *     DOM node. Note that this is fired for each DOM node. aArea is the area
   *     that was reset, aContainer the DOM node that was reset.
   *
   *   - onWidgetCreated(aWidgetId)
   *     Fired when a widget with id aWidgetId has been created, but before it
   *     is added to any placements or any DOM nodes have been constructed.
   *     Only fired for API-based widgets.
   *   - onWidgetAfterCreation(aWidgetId, aArea)
   *     Fired after a widget with id aWidgetId has been created, and has been
   *     added to either its default area or the area in which it was placed
   *     previously. If the widget has no default area and/or it has never
   *     been placed anywhere, aArea may be null. Only fired for API-based
   *     widgets.
   *   - onWidgetDestroyed(aWidgetId)
   *     Fired when widgets are destroyed. aWidgetId is the widget that is
   *     being destroyed. Only fired for API-based widgets.
   *   - onWidgetInstanceRemoved(aWidgetId, aDocument)
   *     Fired when a window is unloaded and a widget's instance is destroyed
   *     because of this. Only fired for API-based widgets.
   *
   *   - onWidgetDrag(aWidgetId, aArea)
   *     Fired both when and after customize mode drag handling system tries
   *     to determine the width and height of widget aWidgetId when dragged to a
   *     different area. aArea will be the area the item is dragged to, or
   *     undefined after the measurements have been done and the node has been
   *     moved back to its 'regular' area.
   *
   *   - onCustomizeStart(aWindow)
   *     Fired when opening customize mode in aWindow.
   *   - onCustomizeEnd(aWindow)
   *     Fired when exiting customize mode in aWindow.
   *
   *   - onWidgetOverflow(aNode, aContainer)
   *     Fired when a widget's DOM node is overflowing its container, a toolbar,
   *     and will be displayed in the overflow panel.
   *   - onWidgetUnderflow(aNode, aContainer)
   *     Fired when a widget's DOM node is *not* overflowing its container, a
   *     toolbar, anymore.
   *   - onWindowOpened(aWindow)
   *     Fired when a window has been opened that is managed by CustomizableUI,
   *     once all of the prerequisite setup has been done.
   *   - onWindowClosed(aWindow)
   *     Fired when a window that has been managed by CustomizableUI has been
   *     closed.
   *   - onAreaNodeRegistered(aArea, aContainer)
   *     Fired after an area node is first built when it is registered. This
   *     is often when the window has opened, but in the case of add-ons,
   *     could fire when the node has just been registered with CustomizableUI
   *     after an add-on update or disable/enable sequence.
   *   - onAreaNodeUnregistered(aArea, aContainer, aReason)
   *     Fired when an area node is explicitly unregistered by an API caller,
   *     or by a window closing. The aReason parameter indicates which of
   *     these is the case.

   *                  passing the document from which it was removed. This is
   *                  useful especially for 'view' type widgets that need to
   *                  cleanup after views that were constructed on the fly.
   * - onBeforeCommand(aEvt): A function that will be invoked when the user
   *                          activates the button but before the command
   *                          is evaluated. Useful if code needs to run to
   *                          change the button's icon in preparation to the
   *                          pending command action. Called for both type=button
   *                          and type=view.
   * - onCommand(aEvt): Only useful for button widgets; a function that will be
   *                    invoked when the user activates the button.
   * - onClick(aEvt): Attached to all widgets; a function that will be invoked
   *                  when the user clicks the widget.
   * - onViewShowing(aEvt): Only useful for views; a function that will be
   *                  invoked when a user shows your view. If any event
   *                  handler calls aEvt.preventDefault(), the view will
   *                  not be shown.
   *
   *                  The event's `detail` property is an object with an
   *                  `addBlocker` method. Handlers which need to
   *                  perform asynchronous operations before the view is
   *                  shown may pass this method a Promise, which will
   *                  prevent the view from showing until it resolves.
   *                  Additionally, if the promise resolves to the exact
   *                  value `false`, the view will not be shown.
   * - onViewHiding(aEvt): Only useful for views; a function that will be
   *                  invoked when a user hides your view.
   * - tooltiptext:   string to use for the tooltip of the widget
   * - label:         string to use for the label of the widget
   * - localized:     If true, or undefined, attempt to retrieve the
   *                  widget's string properties from the customizable
   *                  widgets string bundle.
   * - removable:     whether the widget is removable (optional, default: true)
   *                  NB: if you specify false here, you must provide a

   * - overflows:     whether widget can overflow when in an overflowable
   *                  toolbar (optional, default: true)
   * - defaultArea:   default area to add the widget to

   * - shortcutId:    id of an element that has a shortcut for this widget
   *                  (optional, default: null). This is only used to display
   *                  the shortcut as part of the tooltip for builtin widgets

   * The customize mode transition has 4 phases when entering:
   * 1) Pre-customization mode
   *    This is the starting phase of the browser.
   * 2) LWT swapping
   *    This is where we swap some of the lightweight theme styles in order
   *    to make them work in customize mode. We set/unset a customization-
   *    lwtheme attribute iff we're using a lightweight theme.
   * 3) customize-entering
   *    This phase is a transition, optimized for smoothness.
   * 4) customize-entered
   *    After the transition completes, this phase draws all of the
   *    expensive detail that isn't necessary during the second phase.
   *
   * Exiting customization mode has a similar set of phases, but in reverse
   * order - customize-entered, customize-exiting, remove LWT swapping,
   * pre-customization mode.
   *
   * When in the customize-entering, customize-entered, or customize-exiting
   * phases, there is a "customizing" attribute set on the main-window to simplify

   * Each migration resource should provide:
   * - a |type| getter, returning any of the migration types (see
   *   nsIBrowserProfileMigrator).
   *
   * - a |migrate| method, taking a single argument, aCallback(bool success),

   *   aCallback(bool aSuccess) when it's done.  In the case of an exception
   *   thrown from |migrate|, it's taken as if aCallback(false) is called.
   *
   *   Note: In the case of a simple asynchronous implementation, you may find
   *   MigrationUtils.wrapMigrateFunction handy for handling aCallback easily.
   *
   * For each migration type listed in nsIBrowserProfileMigrator, multiple
   * migration resources may be provided.  This practice is useful when the
   * data for a certain migration type is independently stored in few
   * locations.  For example, the mac version of Safari stores its "reading list"
   * bookmarks in a separate property list.
   *
   * Note that the importation of a particular migration type is reported as
   * successful if _any_ of its resources succeeded to import (that is, called,
   * |aCallback(true)|).  However, completion-status for a particular migration
   * type is reported to the UI only once all of its migrators have called
   * aCallback.
   *
   * @note  The returned array should only include resources from which data
   *        can be imported.  So, for example, before adding a resource for the
   *        BOOKMARKS migration type, you should check if you should check that the
   *        bookmarks file exists.
   *
   * @param aProfile

/**
 * A single page action.
 *
 * Each action can have both per-browser-window state and global state.
 * Per-window state takes precedence over global state.  This is reflected in
 * the title, tooltip, disabled, and icon properties.  Each of these properties
 * has a getter method and setter method that takes a browser window.  Pass null
 * to get the action's global state.  Pass a browser window to get the per-
 * window state.  However, if you pass a window and the action has no state for
 * that window, then the global state will be returned.
 *
 * `options` is a required object with the following properties.  Regarding the
 * properties discussed in the previous paragraph, the values in `options` set
 * global state.
 *
 * @param id (string, required)
 *        The action's ID.  Treat this like the ID of a DOM node.
 * @param title (string, required)
 *        The action's title.
 * @param anchorIDOverride (string, optional)
 *        Pass a string to override the node to which the action's activated-
 *        action panel is anchored.
 * @param disabled (bool, optional)
 *        Pass true to cause the action to be disabled initially in all browser
 *        windows.  False by default.
 * @param extensionID (string, optional)
 *        If the action lives in an extension, pass its ID.
 * @param iconURL (string or object, optional)
 *        The URL string of the action's icon.  Usually you want to specify an
 *        icon in CSS, but this option is useful if that would be a pain for
 *        some reason.  You can also pass an object that maps pixel sizes to
 *        URLs, like { 16: url16, 32: url32 }.  The best size for the user's
 *        screen will be used.
 * @param nodeAttributes (object, optional)
 *        An object of name-value pairs.  Each pair will be added as an
 *        attribute to DOM nodes created for this action.
 * @param onBeforePlacedInWindow (function, optional)
 *        Called before the action is placed in the window:
 *        onBeforePlacedInWindow(window)
 *        * window: The window that the action will be placed in.
 * @param onCommand (function, optional)
 *        Called when the action is clicked, but only if it has neither a
 *        subview nor an iframe:
 *        onCommand(event, buttonNode)
 *        * event: The triggering event.
 *        * buttonNode: The button node that was clicked.
 * @param onIframeHiding (function, optional)
 *        Called when the action's iframe is hiding:
 *        onIframeHiding(iframeNode, parentPanelNode)
 *        * iframeNode: The iframe.
 *        * parentPanelNode: The panel node in which the iframe is shown.
 * @param onIframeHidden (function, optional)
 *        Called when the action's iframe is hidden:
 *        onIframeHidden(iframeNode, parentPanelNode)
 *        * iframeNode: The iframe.
 *        * parentPanelNode: The panel node in which the iframe is shown.
 * @param onIframeShowing (function, optional)
 *        Called when the action's iframe is showing to the user:
 *        onIframeShowing(iframeNode, parentPanelNode)
 *        * iframeNode: The iframe.
 *        * parentPanelNode: The panel node in which the iframe is shown.
 * @param onLocationChange (function, optional)
 *        Called after tab switch or when the current <browser>'s location
 *        changes:
 *        onLocationChange(browserWindow)
 *        * browserWindow: The browser window containing the tab switch or
 *          changed <browser>.
 * @param onPlacedInPanel (function, optional)
 *        Called when the action is added to the page action panel in a browser
 *        window:
 *        onPlacedInPanel(buttonNode)
 *        * buttonNode: The action's node in the page action panel.
 * @param onPlacedInUrlbar (function, optional)
 *        Called when the action is added to the urlbar in a browser window:
 *        onPlacedInUrlbar(buttonNode)
 *        * buttonNode: The action's node in the urlbar.
 * @param onRemovedFromWindow (function, optional)
 *        Called after the action is removed from a browser window:
 *        onRemovedFromWindow(browserWindow)
 *        * browserWindow: The browser window that the action was removed from.
 * @param onShowingInPanel (function, optional)
 *        Called when a browser window's page action panel is showing:
 *        onShowingInPanel(buttonNode)
 *        * buttonNode: The action's node in the page action panel.
 * @param pinnedToUrlbar (bool, optional)
 *        Pass true to pin the action to the urlbar.  An action is shown in the
 *        urlbar if it's pinned and not disabled.  False by default.
 * @param subview (object, optional)
 *        An options object suitable for passing to the Subview constructor, if
 *        you'd like the action to have a subview.  See the subview constructor
 *        for info on this object's properties.
 * @param tooltip (string, optional)
 *        The action's button tooltip text.
 * @param urlbarIDOverride (string, optional)
 *        Usually the ID of the action's button in the urlbar will be generated
 *        automatically.  Pass a string for this property to override that with
 *        your own ID.
 * @param wantsIframe (bool, optional)
 *        Pass true to make an action that shows an iframe in a panel when
 *        clicked.

/**
 * PermissionUI is responsible for exposing both a prototype
 * PermissionPrompt that can be used by arbitrary browser
 * components and add-ons, but also hosts the implementations of
 * built-in permission prompts.
 *
 * If you're developing a feature that requires web content to ask
 * for special permissions from the user, this module is for you.
 *
 * Suppose a system add-on wants to add a new prompt for a new request
 * for getting more low-level access to the user's sound card, and the
 * permission request is coming up from content by way of the
 * nsContentPermissionHelper. The system add-on could then do the following:
 *
 * Cu.import("resource://gre/modules/Integration.jsm");
 * Cu.import("resource:///modules/PermissionUI.jsm");
 *
 * const SoundCardIntegration = (base) => ({
 *   __proto__: base,
 *   createPermissionPrompt(type, request) {
 *     if (type != "sound-api") {
 *       return super.createPermissionPrompt(...arguments);
 *     }
 *
 *     return {
 *       __proto__: PermissionUI.PermissionPromptForRequestPrototype,
 *       get permissionKey() {
 *         return "sound-permission";
 *       }
 *       // etc - see the documentation for PermissionPrompt for
 *       // a better idea of what things one can and should override.
 *     }
 *   },
 * });
 *
 * // Add-on startup:
 * Integration.contentPermission.register(SoundCardIntegration);
 * // ...
 * // Add-on shutdown:
 * Integration.contentPermission.unregister(SoundCardIntegration);
 *
 * Note that PermissionPromptForRequestPrototype must be used as the
 * prototype, since the prompt is wrapping an nsIContentPermissionRequest,
 * and going through nsIContentPermissionPrompt.
 *
 * It is, however, possible to take advantage of PermissionPrompt without
 * having to go through nsIContentPermissionPrompt or with a
 * nsIContentPermissionRequest. The PermissionPromptPrototype can be
 * imported, subclassed, and have prompt() called directly, without
 * the caller having called into createPermissionPrompt.

 * ============================
 *
 * The Policies object below is where the implementation for each policy
 * happens. An object for each policy should be defined, containing
 * callback functions that will be called by the engine.
 *
 * See the _callbacks object in EnterprisePolicies.js for the list of
 * possible callbacks and an explanation of each.
 *
 * Each callback will be called with two parameters:
 * - manager
 *   This is the EnterprisePoliciesManager singleton object from
 *   EnterprisePolicies.js
 *
 * - param
 *   The parameter defined for this policy in policies-schema.json.
 *   It will be different for each policy. It could be a boolean,
 *   a string, an array or a complex object. All parameters have
 *   been validated according to the schema, and no unknown
 *   properties will be present on them.
 *
 * The callbacks will be bound to their parent policy object.

 * This module implements the policy to block websites from being visited,
 * or to only allow certain websites to be visited.
 *
 * The blocklist takes as input an array of MatchPattern strings, as documented
 * at https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Match_patterns.
 *
 * The exceptions list takes the same as input. This list opens up
 * exceptions for rules on the blocklist that might be too strict.
 *
 * In addition to that, this allows the user to create a whitelist approach,
 * by using the special "<all_urls>" pattern for the blocklist, and then
 * adding all whitelisted websites on the exceptions list.
 *
 * Note that this module only blocks top-level website navigations. It doesn't
 * block any other accesses to these urls: image tags, scripts, XHR, etc.,
 * because that could cause unexpected breakage. This is a policy to block
 * users from visiting certain websites, and not from blocking any network
 * connections to those websites. If the admin is looking for that, the recommended
 * way is to configure that with extensions or through a company firewall.

 * This module implements the content side of session restoration. The chrome

 * by content-sessionStore.js based on messages received from SessionStore.jsm
 * (or, in one case, based on a "load" event). Each tab has its own
 * ContentRestore instance, constructed by content-sessionStore.js.
 *
 * In a typical restore, content-sessionStore.js will call the following based
 * on messages and events it receives:
 *
 *   restoreHistory(tabData, loadArguments, callbacks)
 *     Restores the tab's history and session cookies.
 *   restoreTabContent(loadArguments, finishCallback)
 *     Starts loading the data for the current page to restore.
 *   restoreDocument()
 *     Restore form and scroll data.
 *
 * When the page has been loaded from the network, we call finishCallback. It
 * should send a message to SessionStore.jsm, which may cause other tabs to be
 * restored.
 *
 * When the page has finished loading, a "load" event will trigger in
 * content-sessionStore.js, which will call restoreDocument. At that point,
 * form data is restored and the restore is complete.
 *
 * At any time, SessionStore.jsm can cancel the ongoing restore by sending a
 * reset message, which causes resetRestore to be called. At that point it's
 * legal to begin another restore.

/**
 * Helper function to swap the text of a TranslationItem
 * between its original and translated states.
 * How it works:
 *
 * The function iterates through the target array (either the `original` or
 * `translation` array from the TranslationItem), while also keeping a pointer
 * to a current position in the child nodes from the actual DOM node that we
 * are modifying. This pointer is moved forward after each item of the array
 * is translated. If, at any given time, the pointer doesn't match the expected
 * node that was supposed to be seen, it means that the original and translated
 * contents have a different ordering, and thus we need to adjust that.
 *
 * A full example of the reordering process, swapping from Original to
 * Translation:
 *
 *    Original (en): <div>I <em>miss</em> <b>you</b></div>
 *
 * Translation (fr): <div><b>Tu</b> me <em>manques</em></div>
 *
 * Step 1:
 *   pointer points to firstChild of the DOM node, textnode "I "
 *   first item in item.translation is [object TranslationItem <b>]
 *
 *   pointer does not match the expected element, <b>. So let's move <b> to the
 *   pointer position.
 *
 *   Current state of the DOM:
 *     <div><b>you</b>I <em>miss</em> </div>
 *
 * Step 2:
 *   pointer moves forward to nextSibling, textnode "I " again.
 *   second item in item.translation is the string " me "
 *
 *   pointer points to a text node, and we were expecting a text node. Match!
 *   just replace the text content.
 *
 *   Current state of the DOM:
 *     <div><b>you</b> me <em>miss</em> </div>
 *
 * Step 3:
 *   pointer moves forward to nextSibling, <em>miss</em>
 *   third item in item.translation is [object TranslationItem <em>]
 *
 *   pointer points to the expected node. Match! Nothing to do.
 *
 * Step 4:
 *   all items in this item.translation were transformed. The remaining
 *   text nodes are cleared to "", and domNode.normalize() removes them.
 *
 *   Current state of the DOM:
 *     <div><b>you</b> me <em>miss</em></div>
 *
 * Further steps:
 *   After that, the function will visit the child items (from the visitStack),
 *   and the text inside the <b> and <em> nodes will be swapped as well,
 *   yielding the final result:
 *
 *     <div><b>Tu</b> me <em>manques</em></div>
 *
 *
 * @param item     A TranslationItem object
 * @param target   A string that is either "translation"
 *                 or "original".

    // If it's not pointing to it, that means some sort of node reordering
    // will be necessary to produce the correct translation.

    // this better aligns the resulting translation with the DOM content of the
    // page, avoiding cases that would need to be unecessarily reordered.
    //
    // An example of how this helps:

    //   1 - start pointer at textnode 1
    //   2 - move item 1 to first position inside the <div>
    //
    //       Node now looks like: <div><b>Hello </b>[         ][ world.]</div>

    //   1 - start pointer at item 1
    //   2 - item 1 is already in position
    //   3 - replace textnode 2 with " Welt."

<!-- This overlay provides a downloads view that lists both session downloads,
     using the DownloadsView API, and history downloads, using places queries.
     The view also implements a command controller and a context menu for
     managing the downloads list.  In order to use this view:
     1. Apply this overlay to your window.
     2. Insert in all the overlay entry-points, namely:
        <richlistbox id="downloadsRichListBox"/>
        <commandset id="downloadCommands"/>
        <menupopup id="downloadsContextMenu"/>
    3. Make sure your window has the editMenuOverlay overlay applied,
       because the view implements cmd_copy and cmd_delete.
    4. Make sure your window has the globalOverlay.js script loaded.
    5. To initialize the view
        let view = new DownloadsPlacesView(document.getElementById("downloadsRichListBox"));
        // This is what the Places Library uses. It could be tweaked a bit as long as the
        // transition-type is set correctly
        view.place = "place:transition=7&sort=4";

/**
 * A few words on focus and focusrings
 *
 * We do quite a few hacks in the Downloads Panel for focusrings. In fact, we
 * basically suppress most if not all XUL-level focusrings, and style/draw
 * them ourselves (using :focus instead of -moz-focusring). There are a few
 * reasons for this:
 *
 * 1) Richlists on OSX don't have focusrings; instead, they are shown as
 *    selected. This makes for some ambiguity when we have a focused/selected
 *    item in the list, and the mouse is hovering a completed download (which
 *    highlights).
 * 2) Windows doesn't show focusrings until after the first time that tab is
 *    pressed (and by then you're focusing the second item in the panel).
 * 3) Richlistbox sets -moz-focusring even when we select it with a mouse.
 *
 * In general, the desired behaviour is to focus the first item after pressing
 * tab/down, and show that focus with a ring. Then, if the mouse moves over
 * the panel, to hide that focus ring; essentially resetting us to the state
 * before pressing the key.
 *
 * We end up capturing the tab/down key events, and preventing their default
 * behaviour. We then set a "keyfocus" attribute on the panel, which allows
 * us to draw a ring around the currently focused element. If the panel is
 * closed or the mouse moves over the panel, we remove the attribute.

  <h2 id="license-grants-and-conditions">2. License Grants and
  Conditions</h2>

  <h3 id="grants">2.1. Grants</h3>

  <p>Each Contributor hereby grants You a world-wide, royalty-free,
  non-exclusive license:</p>

  <ol type="a">
    <li>
      <p>under intellectual property rights (other than patent or trademark)
      Licensable by such Contributor to use, reproduce, make available,
      modify, display, perform, distribute, and otherwise exploit its
      Contributions, either on an unmodified basis, with Modifications, or as
      part of a Larger Work; and</p>
    </li>

    <li>
      <p>under Patent Claims of such Contributor to make, use, sell, offer
      for sale, have made, import, and otherwise transfer either its
      Contributions or its Contributor Version.</p>
    </li>
  </ol>

  <h3 id="effective-date">2.2. Effective Date</h3>

  <p>The licenses granted in Section 2.1 with respect to any Contribution
  become effective for each Contribution on the date the Contributor first
  distributes such Contribution.</p>

  <h3 id="limitations-on-grant-scope">2.3. Limitations on Grant Scope</h3>

  <p>The licenses granted in this Section 2 are the only rights granted under
  this License. No additional rights or licenses will be implied from the
  distribution or licensing of Covered Software under this License.
  Notwithstanding Section 2.1(b) above, no patent license is granted by a
  Contributor:</p>

  <ol type="a">
    <li>
      <p>for any code that a Contributor has removed from Covered Software;
      or</p>
    </li>

    <li>
      <p>for infringements caused by: (i) Your and any other third party's
      modifications of Covered Software, or (ii) the combination of its
      Contributions with other software (except as part of its Contributor
      Version); or</p>
    </li>

    <li>
      <p>under Patent Claims infringed by Covered Software in the absence of
      its Contributions.</p>
    </li>
  </ol>

  <p>This License does not grant any rights in the trademarks, service marks,
  or logos of any Contributor (except as may be necessary to comply with the
  notice requirements in Section 3.4).</p>

  <h3 id="subsequent-licenses">2.4. Subsequent Licenses</h3>

  <p>No Contributor makes additional grants as a result of Your choice to
  distribute the Covered Software under a subsequent version of this License
  (see Section 10.2) or under the terms of a Secondary License (if permitted
  under the terms of Section 3.3).</p>

  <h3 id="representation">2.5. Representation</h3>

  <p>Each Contributor represents that the Contributor believes its
  Contributions are its original creation(s) or it has sufficient rights to
  grant the rights to its Contributions conveyed by this License.</p>

  <h3 id="fair-use">2.6. Fair Use</h3>

  <p>This License is not intended to limit any rights You have under
  applicable copyright doctrines of fair use, fair dealing, or other
  equivalents.</p>

  <h3 id="conditions">2.7. Conditions</h3>

  <p>Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
  in Section 2.1.</p>

  <h2 id="responsibilities">3. Responsibilities</h2>

  <h3 id="distribution-of-source-form">3.1. Distribution of Source Form</h3>

  <p>All distribution of Covered Software in Source Code Form, including any
  Modifications that You create or to which You contribute, must be under the
  terms of this License. You must inform recipients that the Source Code Form
  of the Covered Software is governed by the terms of this License, and how
  they can obtain a copy of this License. You may not attempt to alter or
  restrict the recipients' rights in the Source Code Form.</p>

  <h3 id="distribution-of-executable-form">3.2. Distribution of Executable
  Form</h3>

  <p>If You distribute Covered Software in Executable Form then:</p>

  <ol type="a">
    <li>
      <p>such Covered Software must also be made available in Source Code
      Form, as described in Section 3.1, and You must inform recipients of
      the Executable Form how they can obtain a copy of such Source Code Form
      by reasonable means in a timely manner, at a charge no more than the
      cost of distribution to the recipient; and</p>
    </li>

    <li>
      <p>You may distribute such Executable Form under the terms of this
      License, or sublicense it under different terms, provided that the
      license for the Executable Form does not attempt to limit or alter the
      recipients' rights in the Source Code Form under this License.</p>
    </li>
  </ol>

  <h3 id="distribution-of-a-larger-work">3.3. Distribution of a Larger
  Work</h3>

  <p>You may create and distribute a Larger Work under terms of Your choice,
  provided that You also comply with the requirements of this License for the
  Covered Software. If the Larger Work is a combination of Covered Software
  with a work governed by one or more Secondary Licenses, and the Covered
  Software is not Incompatible With Secondary Licenses, this License permits
  You to additionally distribute such Covered Software under the terms of
  such Secondary License(s), so that the recipient of the Larger Work may, at
  their option, further distribute the Covered Software under the terms of
  either this License or such Secondary License(s).</p>

  <h3 id="notices">3.4. Notices</h3>

  <p>You may not remove or alter the substance of any license notices
  (including copyright notices, patent notices, disclaimers of warranty, or
  limitations of liability) contained within the Source Code Form of the
  Covered Software, except that You may alter any license notices to the
  extent required to remedy known factual inaccuracies.</p>

  <h3 id="application-of-additional-terms">3.5. Application of Additional
  Terms</h3>

  <p>You may choose to offer, and to charge a fee for, warranty, support,
  indemnity or liability obligations to one or more recipients of Covered
  Software. However, You may do so only on Your own behalf, and not on behalf
  of any Contributor. You must make it absolutely clear that any such
  warranty, support, indemnity, or liability obligation is offered by You
  alone, and You hereby agree to indemnify every Contributor for any
  liability incurred by such Contributor as a result of warranty, support,
  indemnity or liability terms You offer. You may include additional
  disclaimers of warranty and limitations of liability specific to any
  jurisdiction.</p>

  <h2 id="inability-to-comply-due-to-statute-or-regulation">4. Inability to
  Comply Due to Statute or Regulation</h2>

  <p>If it is impossible for You to comply with any of the terms of this
  License with respect to some or all of the Covered Software due to statute,
  judicial order, or regulation then You must: (a) comply with the terms of
  this License to the maximum extent possible; and (b) describe the
  limitations and the code they affect. Such description must be placed in a
  text file included with all distributions of the Covered Software under
  this License. Except to the extent prohibited by statute or regulation,
  such description must be sufficiently detailed for a recipient of ordinary
  skill to be able to understand it.</p>

  <h2 id="termination">5. Termination</h2>

  <h3>5.1.</h3>

  <p>The rights granted under this License will terminate automatically
  if You fail to comply with any of its terms. However, if You become
  compliant, then the rights granted under this License from a particular
  Contributor are reinstated (a) provisionally, unless and until such
  Contributor explicitly and finally terminates Your grants, and (b) on an
  ongoing basis, if such Contributor fails to notify You of the
  non-compliance by some reasonable means prior to 60 days after You have
  come back into compliance. Moreover, Your grants from a particular
  Contributor are reinstated on an ongoing basis if such Contributor notifies
  You of the non-compliance by some reasonable means, this is the first time
  You have received notice of non-compliance with this License from such
  Contributor, and You become compliant prior to 30 days after Your receipt
  of the notice.</p>

  <h3>5.2.</h3>

  <p>If You initiate litigation against any entity by asserting a patent
  infringement claim (excluding declaratory judgment actions, counter-claims,
  and cross-claims) alleging that a Contributor Version directly or
  indirectly infringes any patent, then the rights granted to You by any and
  all Contributors for the Covered Software under Section 2.1 of this License
  shall terminate.</p>

  <h3>5.3.</h3>

  <p>In the event of termination under Sections 5.1 or 5.2 above, all
  end user license agreements (excluding distributors and resellers) which
  have been validly granted by You or Your distributors under this License
  prior to termination shall survive termination.</p>

  <h2 id="disclaimer-of-warranty">6. Disclaimer of Warranty</h2>

  <p><em>Covered Software is provided under this License on an "as is" basis,
  without warranty of any kind, either expressed, implied, or statutory,
  including, without limitation, warranties that the Covered Software is free
  of defects, merchantable, fit for a particular purpose or non-infringing.
  The entire risk as to the quality and performance of the Covered Software
  is with You. Should any Covered Software prove defective in any respect,
  You (not any Contributor) assume the cost of any necessary servicing,
  repair, or correction. This disclaimer of warranty constitutes an essential
  part of this License. No use of any Covered Software is authorized under
  this License except under this disclaimer.</em></p>

  <h2 id="limitation-of-liability">7. Limitation of Liability</h2>

  <p><em>Under no circumstances and under no legal theory, whether tort
  (including negligence), contract, or otherwise, shall any Contributor, or
  anyone who distributes Covered Software as permitted above, be liable to
  You for any direct, indirect, special, incidental, or consequential damages
  of any character including, without limitation, damages for lost profits,
  loss of goodwill, work stoppage, computer failure or malfunction, or any
  and all other commercial damages or losses, even if such party shall have
  been informed of the possibility of such damages. This limitation of
  liability shall not apply to liability for death or personal injury
  resulting from such party's negligence to the extent applicable law
  prohibits such limitation. Some jurisdictions do not allow the exclusion or
  limitation of incidental or consequential damages, so this exclusion and
  limitation may not apply to You.</em></p>

  <h2 id="litigation">8. Litigation</h2>

  <p>Any litigation relating to this License may be brought only in the
  courts of a jurisdiction where the defendant maintains its principal place
  of business and such litigation shall be governed by laws of that
  jurisdiction, without reference to its conflict-of-law provisions. Nothing
  in this Section shall prevent a party's ability to bring cross-claims or
  counter-claims.</p>

  <h2 id="miscellaneous">9. Miscellaneous</h2>

  <p>This License represents the complete agreement concerning the subject
  matter hereof. If any provision of this License is held to be
  unenforceable, such provision shall be reformed only to the extent
  necessary to make it enforceable. Any law or regulation which provides that
  the language of a contract shall be construed against the drafter shall not
  be used to construe this License against a Contributor.</p>

  <h2 id="versions-of-the-license">10. Versions of the License</h2>

  <h3 id="new-versions">10.1. New Versions</h3>

  <p>Mozilla Foundation is the license steward. Except as provided in Section
  10.3, no one other than the license steward has the right to modify or
  publish new versions of this License. Each version will be given a
  distinguishing version number.</p>

  <h3 id="effect-of-new-versions">10.2. Effect of New Versions</h3>

  <p>You may distribute the Covered Software under the terms of the version
  of the License under which You originally received the Covered Software, or
  under the terms of any subsequent version published by the license
  steward.</p>

  <h3 id="modified-versions">10.3. Modified Versions</h3>

  <p>If you create software not governed by this License, and you want to
  create a new license for such software, you may create and use a modified
  version of this License if you rename the license and remove any references
  to the name of the license steward (except to note that such modified
  license differs from this License).</p>

  <h3 id=
  "distributing-source-code-form-that-is-incompatible-with-secondary-licenses">
  10.4. Distributing Source Code Form that is Incompatible With Secondary
  Licenses</h3>

  <p>If You choose to distribute Source Code Form that is Incompatible With
  Secondary Licenses under the terms of this version of the License, the
  notice described in Exhibit B of this License must be attached.</p>

  <h2 id="exhibit-a---source-code-form-license-notice">Exhibit A - Source

<h3><a id="SEC2">Preamble</a></h3>

<p>
  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
</p>
<p>
  This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it.  You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
</p>
<p>
  When we speak of free software, we are referring to freedom of use,
not price.  Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
</p>
<p>
  To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights.  These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
</p>
<p>
  For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you.  You must make sure that they, too, receive or can get the source
code.  If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it.  And you must show them these terms so they know their rights.
</p>
<p>
  We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
</p>
<p>
  To protect each distributor, we want to make it very clear that
there is no warranty for the free library.  Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
</p>
<p>
  Finally, software patents pose a constant threat to the existence of
any free program.  We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder.  Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
</p>
<p>
  Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License.  This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License.  We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
</p>
<p>
  When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library.  The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom.  The Lesser General
Public License permits more lax criteria for linking other code with
the library.
</p>
<p>
  We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License.  It also provides other free software developers Less
of an advantage over competing non-free programs.  These disadvantages
are the reason we use the ordinary General Public License for many
libraries.  However, the Lesser license provides advantages in certain
special circumstances.
</p>
<p>
  For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard.  To achieve this, non-free programs must be
allowed to use the library.  A more frequent case is that a free
library does the same job as widely used non-free libraries.  In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
</p>
<p>
  In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software.  For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
</p>
<p>
  Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
</p>
<p>
  The precise terms and conditions for copying, distribution and
modification follow.  Pay close attention to the difference between a
"work based on the library" and a "work that uses the library".  The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
</p>

<h3><a id="SEC3">TERMS AND CONDITIONS FOR COPYING,
DISTRIBUTION AND MODIFICATION</a></h3>


<p>
<strong>0.</strong>
This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
</p>
<p>
  A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
</p>
<p>
  The "Library", below, refers to any such software library or work
which has been distributed under these terms.  A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language.  (Hereinafter, translation is
included without limitation in the term "modification".)
</p>
<p>
  "Source code" for a work means the preferred form of the work for
making modifications to it.  For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
</p>
<p>
  Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it).  Whether that is true depends on what the Library does
and what the program that uses the Library does.
</p>
<p>
<strong>1.</strong>
You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
</p>
<p>
  You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
</p>
<p>
<strong>2.</strong>
You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
</p>

<ul>
  <li><strong>a)</strong>
       The modified work must itself be a software library.</li>
  <li><strong>b)</strong>
       You must cause the files modified to carry prominent notices
       stating that you changed the files and the date of any change.</li>

  <li><strong>c)</strong>
       You must cause the whole of the work to be licensed at no
       charge to all third parties under the terms of this License.</li>

  <li><strong>d)</strong>
       If a facility in the modified Library refers to a function or a
       table of data to be supplied by an application program that uses
       the facility, other than as an argument passed when the facility
       is invoked, then you must make a good faith effort to ensure that,
       in the event an application does not supply such function or
       table, the facility still operates, and performs whatever part of
       its purpose remains meaningful.
       <p>
       (For example, a function in a library to compute square roots has
       a purpose that is entirely well-defined independent of the
       application.  Therefore, Subsection 2d requires that any
       application-supplied function or table used by this function must
       be optional: if the application does not supply it, the square
       root function must still compute square roots.)</p></li>
</ul>

<p>
These requirements apply to the modified work as a whole.  If identifiable
sections of that work are not derived from the Library, and can be
reasonably considered independent and separate works in themselves, then
this License, and its terms, do not apply to those sections when you
distribute them as separate works.  But when you distribute the same
sections as part of a whole which is a work based on the Library, the
distribution of the whole must be on the terms of this License, whose
permissions for other licensees extend to the entire whole, and thus to
each and every part regardless of who wrote it.
</p>
<p>
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works
based on the Library.
</p>
<p>
In addition, mere aggregation of another work not based on the Library with
the Library (or with a work based on the Library) on a volume of a storage
or distribution medium does not bring the other work under the scope of
this License.
</p>
<p>
<strong>3.</strong>
You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library.  To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License.  (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.)  Do not make any other change in
these notices.
</p>
<p>
  Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
</p>
<p>
  This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
</p>
<p>
<strong>4.</strong>
You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
</p>
<p>
  If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
</p>
<p>
<strong>5.</strong>
A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library".  Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
</p>
<p>
  However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library".  The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
</p>
<p>
  When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library.  The
threshold for this to be true is not precisely defined by law.
</p>
<p>
  If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work.  (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
</p>
<p>
  Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
</p>
<p>
<strong>6.</strong>
As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
</p>
<p>
  You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License.  You must supply a copy of this License.  If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License.  Also, you must do one
of these things:
</p>

<ul>
    <li><strong>a)</strong> Accompany the work with the complete
    corresponding machine-readable source code for the Library
    including whatever changes were used in the work (which must be
    distributed under Sections 1 and 2 above); and, if the work is an
    executable linked with the Library, with the complete
    machine-readable "work that uses the Library", as object code
    and/or source code, so that the user can modify the Library and
    then relink to produce a modified executable containing the
    modified Library.  (It is understood that the user who changes the
    contents of definitions files in the Library will not necessarily
    be able to recompile the application to use the modified
    definitions.)</li>

    <li><strong>b)</strong> Use a suitable shared library mechanism
    for linking with the Library.  A suitable mechanism is one that
    (1) uses at run time a copy of the library already present on the
    user's computer system, rather than copying library functions into
    the executable, and (2) will operate properly with a modified
    version of the library, if the user installs one, as long as the
    modified version is interface-compatible with the version that the
    work was made with.</li>

    <li><strong>c)</strong> Accompany the work with a written offer,
    valid for at least three years, to give the same user the
    materials specified in Subsection 6a, above, for a charge no more
    than the cost of performing this distribution.</li>

    <li><strong>d)</strong> If distribution of the work is made by
    offering access to copy from a designated place, offer equivalent
    access to copy the above specified materials from the same
    place.</li>

    <li><strong>e)</strong> Verify that the user has already received
    a copy of these materials or that you have already sent this user
    a copy.</li>
</ul>

<p>
  For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it.  However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
</p>
<p>
  It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system.  Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
</p>
<p>
<strong>7.</strong> You may place library facilities that are a work
based on the Library side-by-side in a single library together with
other library facilities not covered by this License, and distribute
such a combined library, provided that the separate distribution of
the work based on the Library and of the other library facilities is
otherwise permitted, and provided that you do these two things:
</p>

<ul>
    <li><strong>a)</strong> Accompany the combined library with a copy
    of the same work based on the Library, uncombined with any other
    library facilities.  This must be distributed under the terms of
    the Sections above.</li>

    <li><strong>b)</strong> Give prominent notice with the combined
    library of the fact that part of it is a work based on the
    Library, and explaining where to find the accompanying uncombined
    form of the same work.</li>
</ul>

<p>
<strong>8.</strong> You may not copy, modify, sublicense, link with,
or distribute the Library except as expressly provided under this
License.  Any attempt otherwise to copy, modify, sublicense, link
with, or distribute the Library is void, and will automatically
terminate your rights under this License.  However, parties who have
received copies, or rights, from you under this License will not have
their licenses terminated so long as such parties remain in full
compliance.
</p>
<p>
<strong>9.</strong>
You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Library or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
</p>
<p>
<strong>10.</strong>
Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
</p>
<p>
<strong>11.</strong>
If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all.  For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
</p>
<p>
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
</p>
<p>
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
</p>
<p>
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
</p>
<p>
<strong>12.</strong>
If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded.  In such case, this License incorporates the limitation as if
written in the body of this License.
</p>
<p>
<strong>13.</strong>
The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
</p>
<p>
Each version is given a distinguishing version number.  If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation.  If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
</p>
<p>
<strong>14.</strong>
If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission.  For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this.  Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
</p>
<p>
<strong>NO WARRANTY</strong>
</p>
<p>
<strong>15.</strong>
BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
</p>
<p>
<strong>16.</strong>
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.

<p>This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.</p>

<h3><a id="section0">0. Additional Definitions</a></h3>

<p>As used herein, &ldquo;this License&rdquo; refers to version 3 of the GNU Lesser
General Public License, and the &ldquo;GNU GPL&rdquo; refers to version 3 of the GNU
General Public License.</p>

<p>&ldquo;The Library&rdquo; refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.</p>

<p>An &ldquo;Application&rdquo; is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.</p>

<p>A &ldquo;Combined Work&rdquo; is a work produced by combining or linking an
Application with the Library.  The particular version of the Library
with which the Combined Work was made is also called the &ldquo;Linked
Version&rdquo;.</p>

<p>The &ldquo;Minimal Corresponding Source&rdquo; for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.</p>

<p>The &ldquo;Corresponding Application Code&rdquo; for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.</p>

<h3><a id="section1">1. Exception to Section 3 of the GNU GPL.</a></h3>

<p>You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.</p>

<h3><a id="section2">2. Conveying Modified Versions.</a></h3>

<p>If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:</p>

<ul>
<li>a) under this License, provided that you make a good faith effort to
   ensure that, in the event an Application does not supply the
   function or data, the facility still operates, and performs
   whatever part of its purpose remains meaningful, or</li>

<li>b) under the GNU GPL, with none of the additional permissions of
   this License applicable to that copy.</li>
</ul>

<h3><a id="section3">3. Object Code Incorporating Material from Library Header Files.</a></h3>

<p>The object code form of an Application may incorporate material from
a header file that is part of the Library.  You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:</p>

<ul>
<li>a) Give prominent notice with each copy of the object code that the
   Library is used in it and that the Library and its use are
   covered by this License.</li>

<li>b) Accompany the object code with a copy of the GNU GPL and this license
   document.</li>
</ul>

<h3><a id="section4">4. Combined Works.</a></h3>

<p>You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:</p>

<ul>
<li>a) Give prominent notice with each copy of the Combined Work that
   the Library is used in it and that the Library and its use are
   covered by this License.</li>

<li>b) Accompany the Combined Work with a copy of the GNU GPL and this license
   document.</li>

<li>c) For a Combined Work that displays copyright notices during
   execution, include the copyright notice for the Library among
   these notices, as well as a reference directing the user to the
   copies of the GNU GPL and this license document.</li>

<li>d) Do one of the following:

<ul>
<li>0) Convey the Minimal Corresponding Source under the terms of this
       License, and the Corresponding Application Code in a form
       suitable for, and under terms that permit, the user to
       recombine or relink the Application with a modified version of
       the Linked Version to produce a modified Combined Work, in the
       manner specified by section 6 of the GNU GPL for conveying
       Corresponding Source.</li>

<li>1) Use a suitable shared library mechanism for linking with the
       Library.  A suitable mechanism is one that (a) uses at run time
       a copy of the Library already present on the user's computer
       system, and (b) will operate properly with a modified version
       of the Library that is interface-compatible with the Linked
       Version.</li>
</ul></li>

<li>e) Provide Installation Information, but only if you would otherwise
   be required to provide such information under section 6 of the
   GNU GPL, and only to the extent that such information is
   necessary to install and execute a modified version of the
   Combined Work produced by recombining or relinking the
   Application with a modified version of the Linked Version. (If
   you use option 4d0, the Installation Information must accompany
   the Minimal Corresponding Source and Corresponding Application
   Code. If you use option 4d1, you must provide the Installation
   Information in the manner specified by section 6 of the GNU GPL
   for conveying Corresponding Source.)</li>
</ul>

<h3><a id="section5">5. Combined Libraries.</a></h3>

<p>You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:</p>

<ul>
<li>a) Accompany the combined library with a copy of the same work based
   on the Library, uncombined with any other library facilities,
   conveyed under the terms of this License.</li>

<li>b) Give prominent notice with the combined library that part of it
   is a work based on the Library, and explaining where to find the
   accompanying uncombined form of the same work.</li>
</ul>

<h3><a id="section6">6. Revised Versions of the GNU Lesser General Public License.</a></h3>

<p>The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.</p>

<p>Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License &ldquo;or any later version&rdquo;
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.</p>

<p>If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.</p>

<pre>Version 3, 29 June 2007

Copyright &copy; 2007 Free Software Foundation, Inc.
&lt;<a href="http://fsf.org/">http://fsf.org/</a>&gt;

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.</pre>

<h2><a name="preamble"></a>Preamble</h2>

<p>The GNU General Public License is a free, copyleft license for
software and other kinds of works.</p>

<p>The licenses for most software and other practical works are designed
to take away your freedom to share and change the works.  By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.  We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors.  You can apply it to
your programs, too.</p>

<p>When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.</p>

<p>To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights.  Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.</p>

<p>For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received.  You must make sure that they, too, receive
or can get the source code.  And you must show them these terms so they
know their rights.</p>

<p>Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.</p>

<p>For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software.  For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.</p>

<p>Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so.  This is fundamentally incompatible with the aim of
protecting users' freedom to change the software.  The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable.  Therefore, we
have designed this version of the GPL to prohibit the practice for those
products.  If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.</p>

<p>Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary.  To prevent this, the GPL assures that
patents cannot be used to render the program non-free.</p>

<p>The precise terms and conditions for copying, distribution and
modification follow.</p>

<h2><a name="terms"></a>TERMS AND CONDITIONS</h2>

<h3><a name="section0"></a>0. Definitions.</h3>

<p>&ldquo;This License&rdquo; refers to version 3 of the GNU General Public License.</p>

<p>&ldquo;Copyright&rdquo; also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.</p>

<p>&ldquo;The Program&rdquo; refers to any copyrightable work licensed under this
License.  Each licensee is addressed as &ldquo;you&rdquo;.  &ldquo;Licensees&rdquo; and
&ldquo;recipients&rdquo; may be individuals or organizations.</p>

<p>To &ldquo;modify&rdquo; a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy.  The resulting work is called a &ldquo;modified version&rdquo; of the
earlier work or a work &ldquo;based on&rdquo; the earlier work.</p>

<p>A &ldquo;covered work&rdquo; means either the unmodified Program or a work based
on the Program.</p>

<p>To &ldquo;propagate&rdquo; a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy.  Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.</p>

<p>To &ldquo;convey&rdquo; a work means any kind of propagation that enables other
parties to make or receive copies.  Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.</p>

<p>An interactive user interface displays &ldquo;Appropriate Legal Notices&rdquo;
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License.  If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.</p>

<h3><a name="section1"></a>1. Source Code.</h3>

<p>The &ldquo;source code&rdquo; for a work means the preferred form of the work
for making modifications to it.  &ldquo;Object code&rdquo; means any non-source
form of a work.</p>

<p>A &ldquo;Standard Interface&rdquo; means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.</p>

<p>The &ldquo;System Libraries&rdquo; of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form.  A
&ldquo;Major Component&rdquo;, in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.</p>

<p>The &ldquo;Corresponding Source&rdquo; for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities.  However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work.  For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.</p>

<p>The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.</p>

<p>The Corresponding Source for a work in source code form is that
same work.</p>

<h3><a name="section2"></a>2. Basic Permissions.</h3>

<p>All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met.  This License explicitly affirms your unlimited
permission to run the unmodified Program.  The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work.  This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.</p>

<p>You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force.  You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright.  Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.</p>

<p>Conveying under any other circumstances is permitted solely under
the conditions stated below.  Sublicensing is not allowed; section 10
makes it unnecessary.</p>

<h3><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h3>

<p>No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.</p>

<p>When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.</p>

<h3><a name="section4"></a>4. Conveying Verbatim Copies.</h3>

<p>You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.</p>

<p>You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.</p>

<h3><a name="section5"></a>5. Conveying Modified Source Versions.</h3>

<p>You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:</p>

<ul>
<li>a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.</li>

<li>b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    &ldquo;keep intact all notices&rdquo;.</li>

<li>c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.</li>

<li>d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.</li>
</ul>

<p>A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
&ldquo;aggregate&rdquo; if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit.  Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.</p>

<h3><a name="section6"></a>6. Conveying Non-Source Forms.</h3>

<p>You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:</p>

<ul>
<li>a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.</li>

<li>b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.</li>

<li>c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.</li>

<li>d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.</li>

<li>e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.</li>
</ul>

<p>A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.</p>

<p>A &ldquo;User Product&rdquo; is either (1) a &ldquo;consumer product&rdquo;, which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling.  In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage.  For a particular
product received by a particular user, &ldquo;normally used&rdquo; refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product.  A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.</p>

<p>&ldquo;Installation Information&rdquo; for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source.  The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.</p>

<p>If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information.  But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).</p>

<p>The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed.  Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.</p>

<p>Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.</p>

<h3><a name="section7"></a>7. Additional Terms.</h3>

<p>&ldquo;Additional permissions&rdquo; are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law.  If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.</p>

<p>When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it.  (Additional permissions may be written to require their own
removal in certain cases when you modify the work.)  You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.</p>

<p>Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:</p>

<ul>
<li>a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or</li>

<li>b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or</li>

<li>c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or</li>

<li>d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or</li>

<li>e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or</li>

<li>f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.</li>
</ul>

<p>All other non-permissive additional terms are considered &ldquo;further
restrictions&rdquo; within the meaning of section 10.  If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term.  If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.</p>

<p>If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.</p>

<p>Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.</p>

<h3><a name="section8"></a>8. Termination.</h3>

<p>You may not propagate or modify a covered work except as expressly
provided under this License.  Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).</p>

<p>However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.</p>

<p>Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.</p>

<p>Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License.  If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.</p>

<h3><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h3>

<p>You are not required to accept this License in order to receive or
run a copy of the Program.  Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance.  However,
nothing other than this License grants you permission to propagate or
modify any covered work.  These actions infringe copyright if you do
not accept this License.  Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.</p>

<h3><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h3>

<p>Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License.  You are not responsible
for enforcing compliance by third parties with this License.</p>

<p>An &ldquo;entity transaction&rdquo; is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations.  If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.</p>

<p>You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License.  For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.</p>

<h3><a name="section11"></a>11. Patents.</h3>

<p>A &ldquo;contributor&rdquo; is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based.  The
work thus licensed is called the contributor's &ldquo;contributor version&rdquo;.</p>

<p>A contributor's &ldquo;essential patent claims&rdquo; are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version.  For
purposes of this definition, &ldquo;control&rdquo; includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.</p>

<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.</p>

<p>In the following three paragraphs, a &ldquo;patent license&rdquo; is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement).  To &ldquo;grant&rdquo; such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.</p>

<p>If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients.  &ldquo;Knowingly relying&rdquo; means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.</p>

<p>If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.</p>

<p>A patent license is &ldquo;discriminatory&rdquo; if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License.  You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.</p>

<p>Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.</p>

<h3><a name="section12"></a>12. No Surrender of Others' Freedom.</h3>

<p>If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all.  For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.</p>

<h3><a name="section13"></a>13. Use with the GNU Affero General Public License.</h3>

<p>Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work.  The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.</p>

<h3><a name="section14"></a>14. Revised Versions of this License.</h3>

<p>The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.</p>

<p>Each version is given a distinguishing version number.  If the
Program specifies that a certain numbered version of the GNU General
Public License &ldquo;or any later version&rdquo; applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation.  If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.</p>

<p>If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.</p>

<p>Later license versions may give you additional or different
permissions.  However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.</p>

<h3><a name="section15"></a>15. Disclaimer of Warranty.</h3>

<p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM &ldquo;AS IS&rdquo; WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>

<h3><a name="section16"></a>16. Limitation of Liability.</h3>

<p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.</p>

<h3><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h3>

<p>If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.</p>

<p>END OF TERMS AND CONDITIONS</p>

<h2><a name="howto"></a>How to Apply These Terms to Your New Programs</h2>

<p>If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.</p>

<p>To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the &ldquo;copyright&rdquo; line and a pointer to where the full notice is found.</p>

<pre>    &lt;one line to give the program's name and a brief idea of what it does.&gt;
    Copyright (C) &lt;year&gt;  &lt;name of author&gt;

    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License
    along with this program.  If not, see &lt;http://www.gnu.org/licenses/&gt;.
</pre>

<p>Also add information on how to contact you by electronic and paper mail.</p>

<p>If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:</p>

<pre>    &lt;program&gt;  Copyright (C) &lt;year&gt;  &lt;name of author&gt;
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.
</pre>

<p>The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License.  Of course, your program's commands
might be different; for a GUI interface, you would use an &ldquo;about box&rdquo;.</p>

<p>You should also get your employer (if you work as a programmer) or school,
if any, to sign a &ldquo;copyright disclaimer&rdquo; for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
&lt;<a href="http://www.gnu.org/licenses/">http://www.gnu.org/licenses/</a>&gt;.</p>

<p>The GNU General Public License does not permit incorporating your program
into proprietary programs.  If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library.  If this is what you want to do, use the GNU Lesser General
Public License instead of this License.  But first, please read

   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

   1. Definitions.

      "License" shall mean the terms and conditions for use, reproduction,
      and distribution as defined by Sections 1 through 9 of this document.

      "Licensor" shall mean the copyright owner or entity authorized by
      the copyright owner that is granting the License.

      "Legal Entity" shall mean the union of the acting entity and all
      other entities that control, are controlled by, or are under common
      control with that entity. For the purposes of this definition,
      "control" means (i) the power, direct or indirect, to cause the
      direction or management of such entity, whether by contract or
      otherwise, or (ii) ownership of fifty percent (50%) or more of the
      outstanding shares, or (iii) beneficial ownership of such entity.

      "You" (or "Your") shall mean an individual or Legal Entity
      exercising permissions granted by this License.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

 #
 #  A large portion of the dictionary entries
 #  originate from ICOT Free Software.  The following conditions for ICOT

 #
 #  Each User may also freely distribute the Program, whether in its
 #  original form or modified, to any third party or parties, PROVIDED
 #  that the provisions of Section 3 ("NO WARRANTY") will ALWAYS appear
 #  on, or be attached to, the Program, which is distributed substantially

 #  contravene any of the laws and regulations of the countries having
 #  jurisdiction over the User or the intended distribution itself.
 #
 #  NO WARRANTY
 #
 #  The program was produced on an experimental basis in the course of the
 #  research and development conducted during the project and is provided
 #  to users as so produced on an experimental basis.  Accordingly, the
 #  program is provided without any warranty whatsoever, whether express,

 #  includes, but is not limited to, any warranty of the quality,
 #  performance, merchantability and fitness for a particular purpose of
 #  the program and the nonexistence of any infringement or violation of
 #  any right of any third party.
 #
 #  Each user of the program will agree and understand, and be deemed to
 #  have agreed and understood, that there is no warranty whatsoever for
 #  the program and, accordingly, the entire risk arising from or
 #  otherwise connected with the program is assumed by the user.
 #
 #  Therefore, neither ICOT, the copyright holder, or any other
 #  organization that participated in or was otherwise related to the

 #  and consequential damages, arising out of or otherwise in connection
 #  with the use or inability to use the program or any product, material
 #  or result produced or otherwise obtained by using the program,
 #  regardless of whether they have been advised of, or otherwise had
 #  knowledge of, the possibility of such damages at any time during the
 #  project or thereafter.  Each user will be deemed to have agreed to the
 #  foregoing by his or her commencement of use of the program.  The term
 #  "use" as used herein includes, but is not limited to, the use,
 #  modification, copying and distribution of the program and the
 #  production of secondary products from the program.
 #
 #  In the case where the program, whether in its original form or
 #  modified, was distributed or delivered to or received by a user from
 #  any person, organization or entity other than ICOT, unless it makes or
 #  grants independently of ICOT any specific warranty to the user in
 #  writing, such person, organization or entity, will also be exempted

5. Time Zone Database

  ICU uses the public domain data and code derived from Time Zone
Database for its time zone support. The ownership of the TZ database
is explained in BCP 175: Procedure for Maintaining the Time Zone
Database section 7.

 # 7.  Database Ownership
 #
 #    The TZ database itself is not an IETF Contribution or an IETF
 #    document.  Rather it is a pre-existing and regularly updated work
 #    that is in the public domain, and is intended to remain in the
 #    public domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do
 #    not apply to the TZ Database or contributions that individuals make
 #    to it.  Should any claims be made and substantiated against the TZ
 #    Database, the organization that is providing the IANA
 #    Considerations defined in this RFC, under the memorandum of
 #    understanding with the IETF, currently ICANN, may act in accordance
 #    with all competent court orders.  No ownership claims will be made
 #    by ICANN or the IETF Trust on the database or the code.  Any person
 #    making a contribution to the database or code waives all rights to
 #    future claims in that contribution or in the TZ Database.</pre>

 * The panel is initialized based on data given in the js object passed
 * as window.arguments[0]. The object must have the following fields set:
 *   @ action (String). Possible values:
 *     - "add" - for adding a new item.
 *       @ type (String). Possible values:
 *         - "bookmark"
 *           @ loadBookmarkInSidebar - optional, the default state for the
 *             "Load this bookmark in the sidebar" field.
 *         - "folder"
 *           @ URIList (Array of nsIURI objects) - optional, list of uris to
 *             be bookmarked under the new folder.
 *         - "livemark"
 *       @ uri (nsIURI object) - optional, the default uri for the new item.
 *         The property is not used for the "folder with items" type.
 *       @ title (String) - optional, the default title for the new item.
 *       @ description (String) - optional, the default description for the new
 *         item.
 *       @ defaultInsertionPoint (InsertionPoint JS object) - optional, the
 *         default insertion point for the new item.
 *       @ keyword (String) - optional, the default keyword for the new item.
 *       @ postData (String) - optional, POST data to accompany the keyword.
 *       @ charSet (String) - optional, character-set to accompany the keyword.
 *      Notes:
 *        1) If |uri| is set for a bookmark/livemark item and |title| isn't,
 *           the dialog will query the history tables for the title associated
 *           with the given uri. If the dialog is set to adding a folder with
 *           bookmark items under it (see URIList), a default static title is
 *           used ("[Folder Name]").
 *        2) The index field of the default insertion point is ignored if
 *           the folder picker is shown.
 *     - "edit" - for editing a bookmark item or a folder.
 *       @ type (String). Possible values:
 *         - "bookmark"
 *           @ node (an nsINavHistoryResultNode object) - a node representing
 *             the bookmark.
 *         - "folder" (also applies to livemarks)
 *           @ node (an nsINavHistoryResultNode object) - a node representing
 *             the folder.
 *   @ hiddenRows (Strings array) - optional, list of rows to be hidden
 *     regardless of the item edited or added by the dialog.
 *     Possible values:
 *     - "title"
 *     - "location"
 *     - "description"
 *     - "keyword"
 *     - "tags"
 *     - "loadInSidebar"
 *     - "folderPicker" - hides both the tree and the menu.
 *
 * window.arguments[0].performed is set to true if any transaction has
 * been performed by the dialog.

      populate the searchbox list of available engines and to perform queries.
      That list is accessed here via this.SearchService, and it's that sort of
      Engine that is passed to this binding's observer as aEngine.

      In addition, browser.js fills two lists of autodetected search engines
      (browser.engines and browser.hiddenEngines) as properties of
      mCurrentBrowser.  Those lists contain unnamed JS objects of the form
      { uri:, title:, icon: }, and that's what the searchbar uses to determine
      whether to show any "Add <EngineName>" menu items in the drop-down.

      The two types of engines are currently related by their identifying
      titles (the Engine object's 'name'), although that may change; see bug
      335102.  -->

        This handles key presses specific to the one-off buttons like Tab and
        Alt+Up/Down, and Up/Down keys within the buttons.  Since one-off buttons
        are always used in conjunction with a list of some sort (in this.popup),
        it also handles Up/Down keys that cross the boundaries between list
        items and the one-off buttons.

        If this method handles the key press, then event.defaultPrevented will
        be true when it returns.

        @param event
               The key event.
        @param numListItems
               The number of items in the list.  The reason that this is a
               parameter at all is that the list may contain items at the end
               that should be ignored, depending on the consumer.  That's true
               for the urlbar for example.
        @param allowEmptySelection
               Pass true if it's OK that neither the list nor the one-off
               buttons contains a selection.  Pass false if either the list or
               the one-off buttons (or both) should always contain a selection.
        @param textboxUserValue
               When the last list item is selected and the user presses Down,
               the first one-off becomes selected and the textbox value is
               restored to the value that the user typed.  Pass that value here.
               However, if you pass true for allowEmptySelection, you don't need
               to pass anything for this parameter.  (Pass undefined or null.)

  //
  // We only ever want to send a message to the parent after
  // onLocationChange has fired, since the parent uses the
  // onLocationChange update to clear transient notifications.
  // Sending the message before onLocationChange will result in
  // us creating the notification, and then clearing it very
  // soon after.
  //
  // To account for both cases (onRefreshAttempted before
  // onLocationChange, and onRefreshAttempted after onLocationChange),
  // we'll hold a mapping of DOM Windows that we see get
  // sent through both onLocationChange and onRefreshAttempted.
  // When either run, they'll check the WeakMap for the existence
  // of the DOM Window. If it doesn't exist, it'll add it. If
  // it finds it, it'll know that it's safe to send the message
  // to the parent, since we know that both have fired.
  //
  // The DOM Window is removed from blockedWindows when we notice
  // the nsIWebProgress change state to STATE_STOP for the
  // STATE_IS_WINDOW case.
  //
  // DOM Windows are mapped to a JS object that contains the data
  // to be sent to the parent to show the notification. Since that
  // data is only known when onRefreshAttempted is fired, it's only
  // ever stashed in the map if onRefreshAttempted fires first -

        Search results arrive asynchronously, which means that keypresses may
        arrive before results do and therefore not have the effect the user
        intends.  That's especially likely to happen with the down arrow and
        enter keys due to the one-off search buttons: if the user very quickly
        pastes something in the input, presses the down arrow key, and then hits
        enter, they are probably expecting to visit the first result.  But if
        there are no results, then pressing down and enter will trigger the
        first one-off button.  To prevent that undesirable behavior, certain

// Distributed under an MIT license: http://codemirror.net/LICENSE

// Glue code between CodeMirror and Tern.
//
// Create a CodeMirror.TernServer to wrap an actual Tern server,
// register open documents (CodeMirror.Doc instances) with it, and
// call its methods to activate the assisting functions that Tern
// provides.
//
// Options supported (all optional):
// * defs: An array of JSON definition data structures.
// * plugins: An object mapping plugin names to configuration
//   options.
// * getFile: A function(name, c) that can be used to access files in
//   the project that haven't been loaded yet. Simply do c(null) to
//   indicate that a file is not available.
// * fileFilter: A function(value, docName, doc) that will be applied
//   to documents before passing them on to Tern.
// * switchToDoc: A function(name, doc) that should, when providing a
//   multi-file view, switch the view or focus to the named file.
// * showError: A function(editor, message) that can be used to
//   override the way errors are displayed.
// * completionTip: Customize the content in tooltips for completions.
//   Is passed a single argument—the completion's data as returned by
//   Tern—and may return a string, DOM node, or null to indicate that
//   no tip should be shown. By default the docstring is shown.
// * typeTip: Like completionTip, but for the tooltips shown for type
//   queries.
// * responseFilter: A function(doc, query, request, error, data) that
//   will be applied to the Tern responses before treating them
//
//
// It is possible to run the Tern server in a web worker by specifying
// these additional options:
// * useWorker: Set to true to enable web worker mode. You'll probably
//   want to feature detect the actual value you use here, for example
//   !!window.Worker.
// * workerScript: The main script of the worker. Point this to
//   wherever you are hosting worker.js from this directory.
// * workerDeps: An array of paths pointing (relative to workerScript)
//   to the Acorn and Tern libraries and any Tern plugins you want to
//   load. Or, if you minified those into a single script and included
//   them in the workerScript, simply leave this undefined.

  /**
   * An extension of the "same-value" algorithm as [described for use by ES6 Map
   * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
   *
   * NaN is considered the same as NaN, however -0 and 0 are considered the same
   * value, which is different from the algorithm described by
   * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
   *
   * This is extended further to allow Objects to describe the values they
   * represent, by way of `valueOf` or `equals` (and `hashCode`).
   *
   * Note: because of this extension, the key equality of Immutable.Map and the
   * value equality of Immutable.Set will differ from ES6 Map and Set.
   *
   * ### Defining custom values
   *
   * The easiest way to describe the value an object represents is by implementing
   * `valueOf`. For example, `Date` represents a value by returning a unix
   * timestamp for `valueOf`:
   *
   *     var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
   *     var date2 = new Date(1234567890000);
   *     date1.valueOf(); // 1234567890000
   *     assert( date1 !== date2 );
   *     assert( Immutable.is( date1, date2 ) );
   *
   * Note: overriding `valueOf` may have other implications if you use this object
   * where JavaScript expects a primitive, such as implicit string coercion.
   *
   * For more complex types, especially collections, implementing `valueOf` may
   * not be performant. An alternative is to implement `equals` and `hashCode`.
   *
   * `equals` takes another object, presumably of similar type, and returns true
   * if the it is equal. Equality is symmetrical, so the same result should be
   * returned if this and the argument are flipped.
   *
   *     assert( a.equals(b) === b.equals(a) );
   *
   * `hashCode` returns a 32bit integer number representing the object which will
   * be used to determine how to store the value object in a Map or Set. You must
   * provide both or neither methods, one must not exist without the other.
   *
   * Also, an important relationship between these methods must be upheld: if two
   * values are equal, they *must* return the same hashCode. If the values are not
   * equal, they might have the same hashCode; this is called a hash collision,
   * and while undesirable for performance reasons, it is acceptable.
   *
   *     if (a.equals(b)) {
   *       assert( a.hashCode() === b.hashCode() );
   *     }
   *
   * All Immutable collections implement `equals` and `hashCode`.

 * The Transition component lets you describe a transition from one component
 * state to another _over time_ with a simple declarative API. Most commonly
 * it's used to animate the mounting and unmounting of a component, but can also
 * be used to describe in-place transition states as well.
 *
 * By default the `Transition` component does not alter the behavior of the
 * component it renders, it only tracks "enter" and "exit" states for the components.
 * It's up to you to give meaning and effect to those states. For example we can
 * add styles to a component when it enters or exits:
 *
 * ```jsx
 * import Transition from 'react-transition-group/Transition';
 *
 * const duration = 300;
 *
 * const defaultStyle = {
 *   transition: `opacity ${duration}ms ease-in-out`,
 *   opacity: 0,
 * }
 *
 * const transitionStyles = {
 *   entering: { opacity: 0 },
 *   entered:  { opacity: 1 },
 * };
 *
 * const Fade = ({ in: inProp }) => (
 *   <Transition in={inProp} timeout={duration}>
 *     {(state) => (
 *       <div style={{
 *         ...defaultStyle,
 *         ...transitionStyles[state]
 *       }}>
 *         I'm A fade Transition!
 *       </div>
 *     )}
 *   </Transition>
 * );
 * ```
 *
 * As noted the `Transition` component doesn't _do_ anything by itself to its child component.
 * What it does do is track transition states over time so you can update the
 * component (such as by adding styles or classes) when it changes states.
 *
 * There are 4 main states a Transition can be in:
 *  - `ENTERING`
 *  - `ENTERED`
 *  - `EXITING`
 *  - `EXITED`
 *
 * Transition state is toggled via the `in` prop. When `true` the component begins the
 * "Enter" stage. During this stage, the component will shift from its current transition state,
 * to `'entering'` for the duration of the transition and then to the `'entered'` stage once
 * it's complete. Let's take the following example:
 *
 * ```jsx
 * state= { in: false };
 *
 * toggleEnterState = () => {
 *   this.setState({ in: true });
 * }
 *
 * render() {
 *   return (
 *     <div>
 *       <Transition in={this.state.in} timeout={500} />
 *       <button onClick={this.toggleEnterState}>Click to Enter</button>
 *     </div>
 *   );
 * }
 * ```
 *
 * When the button is clicked the component will shift to the `'entering'` state and
 * stay there for 500ms (the value of `timeout`) when finally switches to `'entered'`.
 *
 * When `in` is `false` the same thing happens except the state moves from `'exiting'` to `'exited'`.

  selectorFactory is a func that is responsible for returning the selector function used to
  compute new props from state, props, and dispatch. For example:
     export default connectAdvanced((dispatch, options) => (state, props) => ({
      thing: state.things[props.thingId],
      saveThing: fields => dispatch(actionCreators.saveThing(props.thingId, fields)),
    }))(YourComponent)
   Access to dispatch is provided to the factory so selectorFactories can bind actionCreators
  outside of their selector as an optimization. Options passed to connectAdvanced are passed to
  the selectorFactory, along with displayName and WrappedComponent, as the second argument.
   Note that selectorFactory is responsible for all caching/memoization of inbound and outbound
  props. Do not use connectAdvanced directly without memoizing results between calls to your
  selector, otherwise the Connect component will re-render on every state or props change.

  connect is a facade over connectAdvanced. It turns its args into a compatible
  selectorFactory, which has the signature:

    (dispatch, options) => (nextState, nextOwnProps) => nextFinalProps
  
  connect passes its args to connectAdvanced as options, which will in turn pass them to
  selectorFactory each time a Connect component instance is instantiated or hot reloaded.

  selectorFactory returns a final props selector from its mapStateToProps,
  mapStateToPropsFactories, mapDispatchToProps, mapDispatchToPropsFactories, mergeProps,
  mergePropsFactories, and pure args.

  The resulting final props selector is called by the Connect component instance whenever
  it receives new props or store state.

/**
 * A generic tree component. See propTypes for the public API.
 *
 * This tree component doesn't make any assumptions about the structure of your
 * tree data. Whether children are computed on demand, or stored in an array in
 * the parent's `_children` property, it doesn't matter. We only require the
 * implementation of `getChildren`, `getRoots`, `getParent`, and `isExpanded`
 * functions.
 *
 * This tree component is well tested and reliable. See the tests in ./tests
 * and its usage in the performance and memory panels in mozilla-central.
 *
 * This tree component doesn't make any assumptions about how to render items in
 * the tree. You provide a `renderItem` function, and this component will ensure
 * that only those items whose parents are expanded and which are visible in the
 * viewport are rendered. The `renderItem` function could render the items as a
 * "traditional" tree or as rows in a table or anything else. It doesn't
 * restrict you to only one certain kind of tree.
 *
 * The tree comes with basic styling for the indent, the arrow, as well as hovered
 * and focused styles which can be override in CSS.
 *
 * ### Example Usage
 *
 * Suppose we have some tree data where each item has this form:
 *
 *     {
 *       id: Number,
 *       label: String,
 *       parent: Item or null,
 *       children: Array of child items,
 *       expanded: bool,
 *     }
 *
 * Here is how we could render that data with this component:
 *
 *     class MyTree extends Component {
 *       static get propTypes() {
 *         // The root item of the tree, with the form described above.
 *         return {
 *           root: PropTypes.object.isRequired
 *         };
 *       },
 *
 *       render() {
 *         return Tree({
 *           itemHeight: 20, // px
 *
 *           getRoots: () => [this.props.root],
 *
 *           getParent: item => item.parent,
 *           getChildren: item => item.children,
 *           getKey: item => item.id,
 *           isExpanded: item => item.expanded,
 *
 *           renderItem: (item, depth, isFocused, arrow, isExpanded) => {
 *             let className = "my-tree-item";
 *             if (isFocused) {
 *               className += " focused";
 *             }
 *             return dom.div({
 *               className,
 *             },
 *               arrow,
 *               // And here is the label for this item.
 *               dom.span({ className: "my-tree-item-label" }, item.label)
 *             );
 *           },
 *
 *           onExpand: item => dispatchExpandActionToRedux(item),
 *           onCollapse: item => dispatchCollapseActionToRedux(item),
 *         });

/**
 * A partial implementation of the MenuItem API provided by electron:
 * https://github.com/electron/electron/blob/master/docs/api/menu-item.md.
 *
 * Missing features:
 *   - id String - Unique within a single menu. If defined then it can be used
 *                 as a reference to this item by the position attribute.
 *   - role String - Define the action of the menu item; when specified the
 *                   click property will be ignored
 *   - sublabel String
 *   - accelerator Accelerator
 *   - icon NativeImage
 *   - position String - This field allows fine-grained definition of the
 *                       specific location within a given menu.
 *
 * Implemented features:
 *  @param Object options
 *    Function click
 *      Will be called with click(menuItem, browserWindow) when the menu item
 *       is clicked
 *    String type
 *      Can be normal, separator, submenu, checkbox or radio
 *    String label
 *    Boolean enabled
 *      If false, the menu item will be greyed out and unclickable.
 *    Boolean checked
 *      Should only be specified for checkbox or radio type menu items.
 *    Menu submenu
 *      Should be specified for submenu type menu items. If submenu is specified,
 *      the type: 'submenu' can be omitted. If the value is not a Menu then it
 *      will be automatically converted to one using Menu.buildFromTemplate.
 *    Boolean visible
 *      If false, the menu item will be entirely hidden.

// ## Token types

// The assignment of fine-grained, information-carrying type objects
// allows the tokenizer to store the information it has about a
// token in a way that is very cheap for the parser to look up.

// All token type variables start with an underscore, to make them
// easy to recognize.

// The `beforeExpr` property is used to disambiguate between regular
// expressions and divisions. It is set on all token types that can
// be followed by an expression (thus, a slash after them would be a
// regular expression).
//
// The `startsExpr` property is used to check if the token ends a

/**
 * An IndexedSourceMapConsumer instance represents a parsed source map which
 * we can query for information. It differs from BasicSourceMapConsumer in
 * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
 * input.
 *
 * The only parameter is a raw source map (either as a JSON string, or already
 * parsed to an object). According to the spec for indexed source maps, they
 * have the following attributes:
 *
 *   - version: Which version of the source map spec this map is following.
 *   - file: Optional. The generated file this source map is associated with.
 *   - sections: A list of section definitions.
 *
 * Each value under the "sections" field has two fields:
 *   - offset: The offset into the original specified at which this section
 *       begins to apply, defined as an object with a "line" and "column"
 *       field.
 *   - map: A source map definition. This source map could also be indexed,
 *       but doesn't have to be.
 *
 * Instead of the "map" field, it's also possible to have a "url" field
 * specifying a URL to retrieve a source map from, but that's currently
 * unsupported.
 *
 * Here's an example source map, taken from the source map spec[0], but
 * modified to omit a section which uses the "url" field.
 *
 *  {
 *    version : 3,
 *    file: "app.js",
 *    sections: [{
 *      offset: {line:100, column:10},
 *      map: {
 *        version : 3,
 *        file: "section.js",
 *        sources: ["foo.js", "bar.js"],
 *        names: ["src", "maps", "are", "fun"],
 *        mappings: "AAAA,E;;ABCDE;"
 *      }
 *    }],

 * ToolSidebar provides methods to register tabs in the sidebar.
 * It's assumed that the sidebar contains a xul:tabbox.
 * Typically, you'll want the tabbox parameter to be a XUL tabbox like this:
 *
 * <tabbox id="inspector-sidebar" handleCtrlTab="false" class="devtools-sidebar-tabs">
 *   <tabs/>
 *   <tabpanels flex="1"/>
 * </tabbox>
 *
 * The ToolSidebar API has a method to add new tabs, so the tabs and tabpanels
 * nodes can be empty. But they can also already contain items before the
 * ToolSidebar is created.
 *
 * Tabs added through the addTab method are only identified by an ID and a URL
 * which is used as the href of an iframe node that is inserted in the newly
 * created tabpanel.
 * Tabs already present before the ToolSidebar is created may contain anything.
 * However, these tabs must have ID attributes if it is required for the various
 * methods that accept an ID as argument to work here.
 *
 * @param {Node} tabbox
 *  <tabbox> node;
 * @param {ToolPanel} panel
 *  Related ToolPanel instance;
 * @param {String} uid
 *  Unique ID
 * @param {Object} options
 *  - hideTabstripe: Should the tabs be hidden. Defaults to false
 *  - showAllTabsMenu: Should a drop-down menu be displayed in case tabs
 *    become hidden. Defaults to false.
 *  - disableTelemetry: By default, switching tabs on and off in the sidebar
 *    will record tool usage in telemetry, pass this option to true to avoid it.
 *
 * Events raised:
 * - new-tab-registered : After a tab has been added via addTab. The tab ID
 *   is passed with the event. This however, is raised before the tab iframe
 *   is fully loaded.
 * - <tabid>-ready : After the tab iframe has been loaded
 * - <tabid>-selected : After tab <tabid> was selected
 * - select : Same as above, but for any tab, the ID is passed with the event
 * - <tabid>-unselected : After tab <tabid> is unselected

/**
 * Model representing JIT optimization sites from the profiler
 * for a frame (represented by a FrameNode). Requires optimization data from
 * a profile, which is an array of RawOptimizationSites.
 *
 * When the ThreadNode for the profile iterates over the samples' frames, each
 * frame's optimizations are accumulated in their respective FrameNodes. Each
 * FrameNode may contain many different optimization sites. One sample may
 * pick up optimization X on line Y in the frame, with the next sample
 * containing optimization Z on line W in the same frame, as each frame is
 * only function.
 *
 * An OptimizationSite contains a record of how many times the
 * RawOptimizationSite was sampled, as well as the unique id based off of the
 * original profiler array, and the RawOptimizationSite itself as a reference.
 * @see devtools/client/performance/modules/logic/tree-model.js
 *
 * @struct RawOptimizationSite
 * A structure describing a location in a script that was attempted to be optimized.
 * Contains all the IonTypes observed, and the sequence of OptimizationAttempts that
 * were attempted, and the line and column in the script. This is retrieved from the
 * profiler after a recording, and our base data structure. Should always be referenced,
 * and unmodified.
 *
 * Note that propertyName is an index into a string table, which needs to be
 * provided in order for the raw optimization site to be inflated.
 *
 * @type {Array<IonType>} types
 * @type {Array<OptimizationAttempt>} attempts
 * @type {?number} propertyName
 * @type {number} line
 * @type {number} column
 *
 *
 * @struct IonType
 * IonMonkey attempts to classify each value in an optimization site by some type.
 * Based off of the observed types for a value (like a variable that could be a
 * string or an instance of an object), it determines what kind of type it should be
 * classified as. Each IonType here contains an array of all ObservedTypes under `types`,
 * the Ion type that IonMonkey decided this value should be (Int32, Object, etc.) as
 * `mirType`, and the component of this optimization type that this value refers to --
 * like a "getter" optimization, `a[b]`, has site `a` (the "Receiver") and `b`
 * (the "Index").
 *
 * Generally the more ObservedTypes, the more deoptimized this OptimizationSite is.
 * There could be no ObservedTypes, in which case `typeset` is undefined.
 *
 * @type {?Array<ObservedType>} typeset
 * @type {string} site
 * @type {string} mirType
 *
 *
 * @struct ObservedType
 * When IonMonkey attempts to determine what type a value is, it checks on each sample.
 * The ObservedType can be thought of in more of JavaScripty-terms, rather than C++.
 * The `keyedBy` property is a high level description of the type, like "primitive",
 * "constructor", "function", "singleton", "alloc-site" (that one is a bit more weird).
 * If the `keyedBy` type is a function or constructor, the ObservedType should have a
 * `name` property, referring to the function or constructor name from the JS source.
 * If IonMonkey can determine the origin of this type (like where the constructor is
 * defined), the ObservedType will also have `location` and `line` properties, but
 * `location` can sometimes be non-URL strings like "self-hosted" or a memory location
 * like "102ca7880", or no location at all, and maybe `line` is 0 or undefined.
 *
 * @type {string} keyedBy
 * @type {?string} name
 * @type {?string} location
 * @type {?string} line
 *
 *
 * @struct OptimizationAttempt
 * Each RawOptimizationSite contains an array of OptimizationAttempts. Generally,
 * IonMonkey goes through a series of strategies for each kind of optimization, starting
 * from most-niche and optimized, to the less-optimized, but more general strategies --
 * for example, a getter opt may first try to optimize for the scenario of a getter on an
 * `arguments` object -- that will fail most of the time, as most objects are not
 * arguments objects, but it will attempt several strategies in order until it finds a
 * strategy that works, or fails. Even in the best scenarios, some attempts will fail
 * (like the arguments getter example), which is OK, as long as some attempt succeeds
 * (with the earlier attempts preferred, as those are more optimized). In an
 * OptimizationAttempt structure, we store just the `strategy` name and `outcome` name,
 * both from enums in js/public/TrackedOptimizationInfo.h as TRACKED_STRATEGY_LIST and
 * TRACKED_OUTCOME_LIST, respectively. An array of successful outcome strings are above
 * in SUCCESSFUL_OUTCOMES.
 *
 * @see js/public/TrackedOptimizationInfo.h
 *
 * @type {string} strategy
 * @type {string} outcome

/**
 * A simple schema for mapping markers to the timeline UI. The keys correspond
 * to marker names, while the values are objects with the following format:
 *
 * - group: The row index in the overview graph; multiple markers
 *          can be added on the same row. @see <overview.js/buildGraphImage>
 * - label: The label used in the waterfall to identify the marker. Can be a
 *          string or just a function that accepts the marker and returns a
 *          string (if you want to use a dynamic property for the main label).
 *          If you use a function for a label, it *must* handle the case where
 *          no marker is provided, to get a generic label used to describe
 *          all markers of this type.
 * - fields: The fields used in the marker details view to display more
 *           information about a currently selected marker. Can either be an
 *           object of fields, or simply a function that accepts the marker and
 *           returns such an object (if you want to use properties dynamically).
 *           For example, a field in the object such as { "Cause": "causeName" }
 *           would render something like `Cause: ${marker.causeName}` in the UI.
 * - colorName: The label of the DevTools color used for this marker. If
 *              adding a new color, be sure to check that there's an entry
 *              for `.marker-color-graphs-{COLORNAME}` for the equivilent
 *              entry in "./devtools/client/themes/performance.css"
 *              https://developer.mozilla.org/en-US/docs/Tools/DevToolsColors
 * - collapsible: Whether or not this marker can contain other markers it
 *                eclipses, and becomes collapsible to reveal its nestable
 *                children. Defaults to true.
 * - nestable: Whether or not this marker can be nested inside an eclipsing
 *             collapsible marker. Defaults to true.

/**
 * A fast, generic, expandable and collapsible tree component.
 *
 * This tree component is fast: it can handle trees with *many* items. It only
 * renders the subset of those items which are visible in the viewport. It's
 * been battle tested on huge trees in the memory panel. We've optimized tree
 * traversal and rendering, even in the presence of cross-compartment wrappers.
 *
 * This tree component doesn't make any assumptions about the structure of your
 * tree data. Whether children are computed on demand, or stored in an array in
 * the parent's `_children` property, it doesn't matter. We only require the
 * implementation of `getChildren`, `getRoots`, `getParent`, and `isExpanded`
 * functions.
 *
 * This tree component is well tested and reliable. See
 * devtools/client/shared/components/test/mochitest/test_tree_* and its usage in
 * the performance and memory panels.
 *
 * This tree component doesn't make any assumptions about how to render items in
 * the tree. You provide a `renderItem` function, and this component will ensure
 * that only those items whose parents are expanded and which are visible in the
 * viewport are rendered. The `renderItem` function could render the items as a
 * "traditional" tree or as rows in a table or anything else. It doesn't
 * restrict you to only one certain kind of tree.
 *
 * The only requirement is that every item in the tree render as the same
 * height. This is required in order to compute which items are visible in the
 * viewport in constant time.
 *
 * ### Example Usage
 *
 * Suppose we have some tree data where each item has this form:
 *
 *     {
 *       id: Number,
 *       label: String,
 *       parent: Item or null,
 *       children: Array of child items,
 *       expanded: bool,
 *     }
 *
 * Here is how we could render that data with this component:
 *
 *     class MyTree extends Component {
 *       static get propTypes() {
 *         // The root item of the tree, with the form described above.
 *         return {
 *           root: PropTypes.object.isRequired
 *         };
 *       }
 *
 *       render() {
 *         return Tree({
 *           itemHeight: 20, // px
 *
 *           getRoots: () => [this.props.root],
 *
 *           getParent: item => item.parent,
 *           getChildren: item => item.children,
 *           getKey: item => item.id,
 *           isExpanded: item => item.expanded,
 *
 *           renderItem: (item, depth, isFocused, arrow, isExpanded) => {
 *             let className = "my-tree-item";
 *             if (isFocused) {
 *               className += " focused";
 *             }
 *             return dom.div(
 *               {
 *                 className,
 *                 // Apply 10px nesting per expansion depth.
 *                 style: { marginLeft: depth * 10 + "px" }
 *               },
 *               // Here is the expando arrow so users can toggle expansion and
 *               // collapse state.
 *               arrow,
 *               // And here is the label for this item.
 *               dom.span({ className: "my-tree-item-label" }, item.label)
 *             );
 *           },
 *
 *           onExpand: item => dispatchExpandActionToRedux(item),
 *           onCollapse: item => dispatchCollapseActionToRedux(item),
 *         });
 *       }

/**
 * A generic tree component. See propTypes for the public API.
 *
 * This tree component doesn't make any assumptions about the structure of your
 * tree data. Whether children are computed on demand, or stored in an array in
 * the parent's `_children` property, it doesn't matter. We only require the
 * implementation of `getChildren`, `getRoots`, `getParent`, and `isExpanded`
 * functions.
 *
 * This tree component is well tested and reliable. See the tests in ./tests
 * and its usage in the performance and memory panels in mozilla-central.
 *
 * This tree component doesn't make any assumptions about how to render items in
 * the tree. You provide a `renderItem` function, and this component will ensure
 * that only those items whose parents are expanded and which are visible in the
 * viewport are rendered. The `renderItem` function could render the items as a
 * "traditional" tree or as rows in a table or anything else. It doesn't
 * restrict you to only one certain kind of tree.
 *
 * The tree comes with basic styling for the indent, the arrow, as well as hovered
 * and focused styles which can be override in CSS.
 *
 * ### Example Usage
 *
 * Suppose we have some tree data where each item has this form:
 *
 *     {
 *       id: Number,
 *       label: String,
 *       parent: Item or null,
 *       children: Array of child items,
 *       expanded: bool,
 *     }
 *
 * Here is how we could render that data with this component:
 *
 *     class MyTree extends Component {
 *       static get propTypes() {
 *         // The root item of the tree, with the form described above.
 *         return {
 *           root: PropTypes.object.isRequired
 *         };
 *       },
 *
 *       render() {
 *         return Tree({
 *           itemHeight: 20, // px
 *
 *           getRoots: () => [this.props.root],
 *
 *           getParent: item => item.parent,
 *           getChildren: item => item.children,
 *           getKey: item => item.id,
 *           isExpanded: item => item.expanded,
 *
 *           renderItem: (item, depth, isFocused, arrow, isExpanded) => {
 *             let className = "my-tree-item";
 *             if (isFocused) {
 *               className += " focused";
 *             }
 *             return dom.div({
 *               className,
 *             },
 *               arrow,
 *               // And here is the label for this item.
 *               dom.span({ className: "my-tree-item-label" }, item.label)
 *             );
 *           },
 *
 *           onExpand: item => dispatchExpandActionToRedux(item),
 *           onCollapse: item => dispatchCollapseActionToRedux(item),
 *         });
 *       }

 * @param {Object} options
 *    Options for the editable field, including:
 *    {Element} element:
 *      (required) The span to be edited on focus.
 *    {Function} canEdit:
 *       Will be called before creating the inplace editor.  Editor
 *       won't be created if canEdit returns false.
 *    {Function} start:
 *       Will be called when the inplace editor is initialized.
 *    {Function} change:
 *       Will be called when the text input changes.  Will be called
 *       with the current value of the text input.
 *    {Function} done:
 *       Called when input is committed or blurred.  Called with
 *       current value, a boolean telling the caller whether to
 *       commit the change, and the direction of the next element to be
 *       selected. Direction may be one of Services.focus.MOVEFOCUS_FORWARD,
 *       Services.focus.MOVEFOCUS_BACKWARD, or null (no movement).
 *       This function is called before the editor has been torn down.
 *    {Function} destroy:
 *       Called when the editor is destroyed and has been torn down.
 *    {Function} contextMenu:
 *       Called when the user triggers a contextmenu event on the input.
 *    {Object} advanceChars:
 *       This can be either a string or a function.
 *       If it is a string, then if any characters in it are typed,
 *       focus will advance to the next element.
 *       Otherwise, if it is a function, then the function will
 *       be called with three arguments: a key code, the current text,
 *       and the insertion point.  If the function returns true,
 *       then the focus advance takes place.  If it returns false,
 *       then the character is inserted instead.
 *    {Boolean} stopOnReturn:
 *       If true, the return key will not advance the editor to the next
 *       focusable element.
 *    {Boolean} stopOnTab:
 *       If true, the tab key will not advance the editor to the next
 *       focusable element.
 *    {Boolean} stopOnShiftTab:
 *       If true, shift tab will not advance the editor to the previous
 *       focusable element.
 *    {String} trigger: The DOM event that should trigger editing,
 *      defaults to "click"
 *    {Boolean} multiline: Should the editor be a multiline textarea?
 *      defaults to false
 *    {Function or Number} maxWidth:
 *       Should the editor wrap to remain below the provided max width. Only
 *       available if multiline is true. If a function is provided, it will be
 *       called when replacing the element by the inplace input.
 *    {Boolean} trimOutput: Should the returned string be trimmed?
 *      defaults to true
 *    {Boolean} preserveTextStyles: If true, do not copy text-related styles
 *              from `element` to the new input.
 *      defaults to false
 *    {Object} cssProperties: An instance of CSSProperties.
 *    {Object} cssVariables: A Map object containing all CSS variables.
 *    {Number} defaultIncrement: The value by which the input is incremented
 *      or decremented by default (0.1 for properties like opacity and 1 by default)

 * - TYPE_URI: a URI (e.g. <a href="uri">).
 * - TYPE_URI_LIST: a space separated list of URIs (e.g. <a ping="uri1 uri2">).
 * - TYPE_IDREF: a reference to an other element in the same document via its id
 *   (e.g. <label for="input-id"> or <key command="command-id">).
 * - TYPE_IDREF_LIST: a space separated list of IDREFs (e.g.
 *   <output for="id1 id2">).
 * - TYPE_JS_RESOURCE_URI: a URI to a javascript resource that can be opened in
 *   the devtools (e.g. <script src="uri">).
 * - TYPE_CSS_RESOURCE_URI: a URI to a css resource that can be opened in the
 *   devtools (e.g. <link href="uri">).

/**
 * This file defines functions to add the ability for redux reducers
 * to broadcast specific state changes to a non-React UI. You should
 * *never* use this for new code that uses React, as it violates the
 * core principals of a functional UI. This should only be used when
 * migrating old code to redux, because it allows you to use redux
 * with event-listening UI elements. The typical way to set all of
 * this up is this:
 *
 *  const emitter = makeEmitter();
 *  let store = createStore(combineEmittingReducers(
 *    reducers,
 *    emitter.emit
 *  ));
 *  store = enhanceStoreWithEmitter(store, emitter);
 *
 * Now reducers will receive a 3rd argument, `emit`, for emitting
 * events, and the store has an `on` function for listening to them.
 * For example, a reducer can now do this:
 *
 * function update(state = initialState, action, emitChange) {
 *   if (action.type === constants.ADD_BREAKPOINT) {
 *     const id = action.breakpoint.id;
 *     emitChange('add-breakpoint', action.breakpoint);
 *     return state.merge({ [id]: action.breakpoint });
 *   }
 *   return state;
 * }
 *
 * `emitChange` is *not* synchronous, the state changes will be
 * broadcasted *after* all reducers are run and the state has been
 * updated.
 *
 * Now, a non-React widget can do this:
 *
 * store.on('add-breakpoint', breakpoint => { ... });

 * waits until all reducers have run and the store has updated the
 * state, and then fires any enqueued events. Events *are* fired
 * synchronously, but just later in the process.
 *
 * This is important because you never want the UI to be updating in
 * the middle of a reducing process. Reducers will fire these events
 * in the middle of generating new state, but the new state is *not*
 * available from the store yet. So if the UI executes in the middle
 * of the reducing process and calls `getState()` to get something

	 * A BasicSourceMapConsumer instance represents a parsed source map which we can

	 * position in the generated source.
	 *
	 * The first parameter is the raw source map (either as a JSON string, or
	 * already parsed to an object). According to the spec, source maps have the
	 * following attributes:
	 *
	 *   - version: Which version of the source map spec this map is following.
	 *   - sources: An array of URLs to the original source files.
	 *   - names: An array of identifiers which can be referrenced by individual mappings.
	 *   - sourceRoot: Optional. The URL root from which all sources are relative.
	 *   - sourcesContent: Optional. An array of contents of the original source files.
	 *   - mappings: A string of base64 VLQs which contain the actual mappings.
	 *   - file: Optional. The generated file this source map is associated with.
	 *
	 * Here is an example source map, taken from the source map spec[0]:
	 *
	 *     {
	 *       version : 3,
	 *       file: "out.js",
	 *       sourceRoot : "",
	 *       sources: ["foo.js", "bar.js"],
	 *       names: ["src", "maps", "are", "fun"],
	 *       mappings: "AA,AB;;ABCDE;"
	 *     }
	 *
	 * The second parameter, if given, is a string whose value is the URL
	 * at which the source map was found.  This URL is used to compute the
	 * sources array.

	 * An IndexedSourceMapConsumer instance represents a parsed source map which
	 * we can query for information. It differs from BasicSourceMapConsumer in
	 * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
	 * input.
	 *
	 * The only parameter is a raw source map (either as a JSON string, or already
	 * parsed to an object). According to the spec for indexed source maps, they
	 * have the following attributes:
	 *
	 *   - version: Which version of the source map spec this map is following.
	 *   - file: Optional. The generated file this source map is associated with.
	 *   - sections: A list of section definitions.
	 *
	 * Each value under the "sections" field has two fields:
	 *   - offset: The offset into the original specified at which this section
	 *       begins to apply, defined as an object with a "line" and "column"
	 *       field.
	 *   - map: A source map definition. This source map could also be indexed,
	 *       but doesn't have to be.
	 *
	 * Instead of the "map" field, it's also possible to have a "url" field
	 * specifying a URL to retrieve a source map from, but that's currently
	 * unsupported.
	 *
	 * Here's an example source map, taken from the source map spec[0], but
	 * modified to omit a section which uses the "url" field.
	 *
	 *  {
	 *    version : 3,
	 *    file: "app.js",
	 *    sections: [{
	 *      offset: {line:100, column:10},
	 *      map: {
	 *        version : 3,
	 *        file: "section.js",
	 *        sources: ["foo.js", "bar.js"],
	 *        names: ["src", "maps", "are", "fun"],

  /**
   * An extension of the "same-value" algorithm as [described for use by ES6 Map
   * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
   *
   * NaN is considered the same as NaN, however -0 and 0 are considered the same
   * value, which is different from the algorithm described by
   * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
   *
   * This is extended further to allow Objects to describe the values they
   * represent, by way of `valueOf` or `equals` (and `hashCode`).
   *
   * Note: because of this extension, the key equality of Immutable.Map and the
   * value equality of Immutable.Set will differ from ES6 Map and Set.
   *
   * ### Defining custom values
   *
   * The easiest way to describe the value an object represents is by implementing
   * `valueOf`. For example, `Date` represents a value by returning a unix
   * timestamp for `valueOf`:
   *
   *     var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
   *     var date2 = new Date(1234567890000);
   *     date1.valueOf(); // 1234567890000
   *     assert( date1 !== date2 );
   *     assert( Immutable.is( date1, date2 ) );
   *
   * Note: overriding `valueOf` may have other implications if you use this object
   * where JavaScript expects a primitive, such as implicit string coercion.
   *
   * For more complex types, especially collections, implementing `valueOf` may
   * not be performant. An alternative is to implement `equals` and `hashCode`.
   *
   * `equals` takes another object, presumably of similar type, and returns true
   * if the it is equal. Equality is symmetrical, so the same result should be
   * returned if this and the argument are flipped.
   *
   *     assert( a.equals(b) === b.equals(a) );
   *
   * `hashCode` returns a 32bit integer number representing the object which will
   * be used to determine how to store the value object in a Map or Set. You must
   * provide both or neither methods, one must not exist without the other.
   *
   * Also, an important relationship between these methods must be upheld: if two
   * values are equal, they *must* return the same hashCode. If the values are not
   * equal, they might have the same hashCode; this is called a hash collision,
   * and while undesirable for performance reasons, it is acceptable.
   *
   *     if (a.equals(b)) {
   *       assert( a.hashCode() === b.hashCode() );
   *     }
   *
   * All Immutable collections implement `equals` and `hashCode`.

   JSOL stands for JavaScript Object Literal which is a string representing
   an object in JavaScript syntax.

   For example:

   {foo:"bar"} is equivalent to {"foo":"bar"} in JavaScript. Both are valid JSOL.

   Note that {"foo":"bar"} is proper JSON[1] therefore you can use one of the many
   JSON parsers out there like json2.js[2] or even the native browser's JSON parser,
   if available.

   However, {foo:"bar"} is NOT proper JSON but valid Javascript syntax for
   representing an object with one key, "foo" and its value, "bar".
   Using a JSON parser is not an option since this is NOT proper JSON.

   You can use JSOL.parse to safely parse any string that reprsents a JavaScript Object Literal.
   JSOL.parse will throw an Invalid JSOL exception on function calls, function declarations and variable references.

   Examples:

   JSOL.parse('{foo:"bar"}');  // valid

   JSOL.parse('{evil:(function(){alert("I\'m evil");})()}');  // invalid function calls

   JSOL.parse('{fn:function() { }}'); // invalid function declarations

   var bar = "bar";
   JSOL.parse('{foo:bar}');  // invalid variable references

   [2] http://www.json.org/json2.js

 *
 * - `level`
 * - `windowBits`
 * - `memLevel`
 * - `strategy`
 * - `dictionary`
 *
 * [http://zlib.net/manual.html#Advanced](http://zlib.net/manual.html#Advanced)
 * for more information on these.
 *
 * Additional options, for internal needs:
 *
 * - `chunkSize` - size of generated data chunks (16K by default)
 * - `raw` (Boolean) - do raw deflate
 * - `gzip` (Boolean) - create gzip wrapper
 * - `to` (String) - if equal to 'string', then result will be "binary string"
 *    (each char code [0..255])
 * - `header` (Object) - custom header for gzip
 *   - `text` (Boolean) - true if compressed data believed to be text
 *   - `time` (Number) - modification time, unix timestamp
 *   - `os` (Number) - operation system code
 *   - `extra` (Array) - array of bytes with extra data (max 65536)
 *   - `name` (String) - file name (binary string)
 *   - `comment` (String) - comment (binary string)
 *   - `hcrc` (Boolean) - true if header crc should be added
 *
 * ##### Example:
 *
 * ```javascript
 * var pako = require('pako')

 *   See constants. Skipped or `false` means Z_NO_FLUSH, `true` meansh Z_FINISH.
 *
 * Sends input data to deflate pipe, generating [[Deflate#onData]] calls with
 * new compressed chunks. Returns `true` on success. The last data block must have
 * mode Z_FINISH (or `true`). That will flush internal pending buffers and call
 * [[Deflate#onEnd]]. For interim explicit flushes (without ending the stream) you
 * can use mode Z_SYNC_FLUSH, keeping the compression context.
 *
 * On fail call [[Deflate#onEnd]] with error code and return false.
 *
 * We strongly recommend to use `Uint8Array` on input for best speed (output
 * array format is detected automatically). Also, don't skip last param and always
 * use the same type in your code (boolean or number). That will improve JS speed.
 *
 * For regular `Array`-s make sure all elements are [0..255].

   Decode literal, length, and distance codes and write out the resulting
   literal and match bytes until either not enough input or output is
   available, an end-of-block is encountered, or a data error is encountered.
   When large enough input and output buffers are supplied to inflate(), for
   example, a 16K input buffer and a 64K output buffer, more than 95% of the
   inflate execution time is spent in this routine.

   Entry assumptions:

        state.mode === LEN
        strm.avail_in >= 6
        strm.avail_out >= 258
        start >= strm.avail_out
        state.bits < 8

   On return, state.mode is one of:

        LEN -- ran out of enough output space or enough available input
        TYPE -- reached end of block code, inflate() to interpret next block
        BAD -- error in block data

   Notes:

    - The maximum input bits used by a length/distance pair is 15 bits for the
      length code, 5 bits for the length extra, 15 bits for the distance code,
      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
      Therefore if strm.avail_in >= 6, then there is enough input to avoid
      checking for available input while decoding.

    - The maximum bytes that a single length/distance pair can output is 258
      bytes, which is the maximum length that can be coded.  inflate_fast()
      requires strm.avail_out >= 258 for each loop to avoid checking for
      output space.

 when a window is already in use, or when output has been written during this

 It is also called to create a window for dictionary data when a dictionary

 Providing output buffers larger than 32K to inflate() should provide a speed
 advantage, since only the last 32K of output is copied to the sliding window
 upon return from inflate(), and since all distances after the first 32K of
 output will fall in the output data, making match copies simpler and faster.
 The advantage may be dependent on the size of the processor's data caches.

   Process a set of code lengths to create a canonical Huffman code.  The
   code lengths are lens[0..codes-1].  Each length corresponds to the
   symbols 0..codes-1.  The Huffman code is generated by first sorting the
   symbols by length from short to long, and retaining the symbol order
   for codes with equal lengths.  Then the code starts with all zero bits
   for the first code of the shortest length, and the codes are integer
   increments for the same length, and zeros are appended as the length
   increases.  For the deflate format, these bits are stored backwards
   from their more natural integer increment ordering, and so when the
   decoding tables are built in the large loop below, the integer codes
   are incremented backwards.

   This routine assumes, but does not check, that all of the entries in
   lens[] are in the range 0..MAXBITS.  The caller must assure this.
   1..MAXBITS is interpreted as that code length.  zero means that that
   symbol does not occur in this code.

   The codes are sorted by computing a count of codes for each length,
   creating from that a table of starting indices for each length in the
   sorted table, and then entering the symbols in order in the sorted
   table.  The sorted table is work[], with that space being provided by
   the caller.

   The length counts are used for other purposes as well, i.e. finding
   the minimum and maximum length codes, determining if there are any
   codes at all, checking for a valid set of lengths, and looking ahead
   at length counts to determine sub-table sizes when building the
   decoding tables.

   Create and fill in decoding tables.  In this loop, the table being
   filled is at next and has curr index bits.  The code being used is huff
   with length len.  That code is converted to an index by dropping drop
   bits off of the bottom.  For codes where len is less than drop + curr,
   those top drop + curr - len bits are incremented through all values to
   fill the table with replicated entries.

   root is the number of index bits for the root table.  When len exceeds
   root, sub-tables are created pointed to by the root entry with an index
   of the low root bits of huff.  This is saved in low to check for when a
   new sub-table should be started.  drop is zero when the root table is
   being filled, and drop is root when sub-tables are being filled.

   When a new sub-table is needed, it is necessary to look ahead in the
   code lengths to determine what size sub-table is needed.  The length
   counts are used for this, and so count[] is decremented as codes are
   entered in the tables.

   used keeps track of how many table entries have been allocated from the
   provided *table space.  It is checked for LENS and DIST tables against
   the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
   the initial root table size constants.  See the comments in inftrees.h
   for more information.

   sym increments through all symbols, and the loop terminates when
   all codes of length max, i.e. all codes, have been processed.  This
   routine permits incomplete codes, so another loop after this one fills
   in the rest of the decoding tables with invalid code markers.

    /**
     * Creates a `lodash` object which wraps `value` to enable implicit method
     * chain sequences. Methods that operate on and return arrays, collections,
     * and functions can be chained together. Methods that retrieve a single value
     * or may return a primitive value will automatically end the chain sequence
     * and return the unwrapped value. Otherwise, the value must be unwrapped
     * with `_#value`.
     *
     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
     * enabled using `_.chain`.
     *
     * The execution of chained methods is lazy, that is, it's deferred until
     * `_#value` is implicitly or explicitly called.
     *
     * Lazy evaluation allows several methods to support shortcut fusion.
     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
     * the creation of intermediate arrays and can greatly reduce the number of
     * iteratee executions. Sections of a chain sequence qualify for shortcut
     * fusion if the section is applied to an array and iteratees accept only
     * one argument. The heuristic for whether a section qualifies for shortcut
     * fusion is subject to change.
     *
     * Chaining is supported in custom builds as long as the `_#value` method is
     * directly or indirectly included in the build.
     *
     * In addition to lodash methods, wrappers have `Array` and `String` methods.
     *
     * The wrapper `Array` methods are:
     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
     *
     * The wrapper `String` methods are:
     * `replace` and `split`
     *
     * The wrapper methods that support shortcut fusion are:
     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
     *
     * The chainable wrapper methods are:
     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

/**
 * Summary of `ReactBrowserEventEmitter` event handling:
 *
 *  - Top-level delegation is used to trap most native browser events. This
 *    may only occur in the main thread and is the responsibility of
 *    ReactDOMEventListener, which is injected and can therefore support
 *    pluggable event sources. This is the only work that occurs in the main
 *    thread.
 *
 *  - We normalize and de-duplicate events to account for browser quirks. This
 *    may be done in the worker thread.
 *
 *  - Forward these native events (with the associated top-level type used to
 *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
 *    to extract any synthetic events.
 *
 *  - The `EventPluginHub` will then process each event by annotating them with
 *    "dispatches", a sequence of listeners and IDs that care about that event.
 *
 *  - The `EventPluginHub` then dispatches the events.

/**
 * We listen for bubbled touch events on the document object.

 * Firefox v8.01 (and possibly others) exhibited strange behavior when

 * element. The symptoms were that if your mouse is not moving over something
 * contained within that mount point (for example on the background) the
 * top-level listeners for `onmousemove` won't be called. However, if you
 * register the `mousemove` on the document object, then it will of course
 * catch all `mousemove`s. This along with iOS quirks, justifies restricting
 * top-level listeners to the document object only, at least for these
 * movement types of events and possibly all events.
 *
 * @see http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html

 * Also, `keyup`/`keypress`/`keydown` do not bubble to the window on IE, but

/**
 * A very generic and low-level tree view implementation. It is not intended
 * to be used alone, but as a base class that you can extend to build your
 * own custom implementation.
 *
 * Language:
 *   - An "item" is an instance of an AbstractTreeItem.
 *   - An "element" or "node" is an nsIDOMNode.
 *
 * The following events are emitted by this tree, always from the root item,
 * with the first argument pointing to the affected child item:
 *   - "expand": when an item is expanded in the tree
 *   - "collapse": when an item is collapsed in the tree
 *   - "focus": when an item is selected in the tree
 *
 * For example, you can extend this abstract class like this:
 *
 * function MyCustomTreeItem(dataSrc, properties) {
 *   AbstractTreeItem.call(this, properties);
 *   this.itemDataSrc = dataSrc;
 * }
 *
 * MyCustomTreeItem.prototype = extend(AbstractTreeItem.prototype, {
 *   _displaySelf: function(document, arrowNode) {
 *     let node = document.createElement("hbox");
 *     ...
 *     // Append the provided arrow node wherever you want.
 *     node.appendChild(arrowNode);
 *     ...
 *     // Use `this.itemDataSrc` to customize the tree item and
 *     // `this.level` to calculate the indentation.
 *     node.style.marginInlineStart = (this.level * 10) + "px";
 *     node.appendChild(document.createTextNode(this.itemDataSrc.label));
 *     ...
 *     return node;
 *   },
 *   _populateSelf: function(children) {
 *     ...
 *     // Use `this.itemDataSrc` to get the data source for the child items.
 *     let someChildDataSrc = this.itemDataSrc.children[0];
 *     ...
 *     children.push(new MyCustomTreeItem(someChildDataSrc, {
 *       parent: this,
 *       level: this.level + 1
 *     }));
 *     ...
 *   }
 * });
 *
 * And then you could use it like this:
 *
 * let dataSrc = {
 *   label: "root",
 *   children: [{
 *     label: "foo",
 *     children: []
 *   }, {
 *     label: "bar",
 *     children: [{
 *       label: "baz",
 *       children: []
 *     }]
 *   }]
 * };
 * let root = new MyCustomTreeItem(dataSrc, { parent: null });
 * root.attachTo(nsIDOMNode);
 * root.expand();
 *
 * The following tree view will be generated (after expanding all nodes):
 * ▼ root
 *   ▶ foo
 *   ▼ bar
 *     ▶ baz
 *
 * The way the data source is implemented is completely up to you. There's
 * no assumptions made and you can use it however you like inside the
 * `_displaySelf` and `populateSelf` methods. If you need to add children to a
 * node at a later date, you just need to modify the data source:
 *
 * dataSrc[...path-to-foo...].children.push({
 *   label: "lazily-added-node"
 *   children: []
 * });
 *
 * The existing tree view will be modified like so (after expanding `foo`):
 * ▼ root
 *   ▼ foo
 *     ▶ lazily-added-node
 *   ▼ bar
 *     ▶ baz
 *
 * Everything else is taken care of automagically!
 *
 * @param AbstractTreeItem parent
 *        The parent tree item. Should be null for root items.
 * @param number level
 *        The indentation level in the tree. The root item is at level 0.

/**
 * Base class for all graphs using a canvas to render the data source. Handles

 *
 * Language:
 *   - The "data" represents the values used when building the graph.
 *     Its specific format is defined by the inheriting classes.
 *
 *   - A "cursor" is the cliphead position across the X axis of the graph.
 *
 *   - A "selection" is defined by a "start" and an "end" value and
 *     represents the selected bounds in the graph.
 *
 *   - A "region" is a highlighted area in the graph, also defined by a
 *     "start" and an "end" value, but distinct from the "selection". It is
 *     simply used to highlight important regions in the data.
 *
 * Instances of this class are EventEmitters with the following events:
 *   - "ready": when the container iframe and canvas are created.
 *   - "selecting": when the selection is set or changed.
 *   - "deselecting": when the selection is dropped.
 *
 * @param nsIDOMNode parent
 *        The parent node holding the graph.
 * @param string name
 *        The graph type, used for setting the correct class names.
 *        Currently supported: "line-graph" only.
 * @param number sharpness [optional]

/**
 * Tooltip widget.
 *
 * This widget is intended at any tool that may need to show rich content in the
 * form of floating panels.
 * A common use case is image previewing in the CSS rule view, but more complex
 * use cases may include color pickers, object inspection, etc...
 *
 * Tooltips are based on XUL (namely XUL arrow-type <panel>s), and therefore
 * need a XUL Document to live in.
 * This is pretty much the only requirement they have on their environment.
 *
 * The way to use a tooltip is simply by instantiating a tooltip yourself and
 * attaching some content in it, or using one of the ready-made content types.
 *
 * A convenient `startTogglingOnHover` method may avoid having to register event
 * handlers yourself if the tooltip has to be shown when hovering over a
 * specific element or group of elements (which is usually the most common case)
 */

/**
 * Tooltip class.
 *
 * Basic usage:
 *   let t = new Tooltip(xulDoc);
 *   t.content = someXulContent;
 *   t.show();
 *   t.hide();
 *   t.destroy();
 *
 * Better usage:
 *   let t = new Tooltip(xulDoc);
 *   t.startTogglingOnHover(container, target => {
 *     if (<condition based on target>) {
 *       t.content = el;
 *       return true;
 *     }
 *   });
 *   t.destroy();
 *
 * @param {XULDocument} doc
 *        The XUL document hosting this tooltip
 * @param {Object} options
 *        Optional options that give options to consumers:
 *        - consumeOutsideClick {Boolean} Wether the first click outside of the
 *        tooltip should close the tooltip and be consumed or not.
 *        Defaults to false.
 *        - closeOnKeys {Array} An array of key codes that should close the
 *        tooltip. Defaults to [27] (escape key).
 *        - closeOnEvents [{emitter: {Object}, event: {String},
 *                          useCapture: {Boolean}}]
 *        Provide an optional list of emitter objects and event names here to
 *        trigger the closing of the tooltip when these events are fired by the
 *        emitters. The emitter objects should either implement
 *        on/off(event, cb) or addEventListener/removeEventListener(event, cb).
 *        Defaults to [].
 *        For instance, the following would close the tooltip whenever the
 *        toolbox selects a new tool and when a DOM node gets scrolled:
 *        new Tooltip(doc, {
 *          closeOnEvents: [
 *            {emitter: toolbox, event: "select"},
 *            {emitter: myContainer, event: "scroll", useCapture: true}
 *          ]
 *        });
 *        - noAutoFocus {Boolean} Should the focus automatically go to the panel
 *        when it opens. Defaults to true.
 *
 * Fires these events:
 * - showing : just before the tooltip shows
 * - shown : when the tooltip is shown
 * - hiding : just before the tooltip closes
 * - hidden : when the tooltip gets hidden
 * - keydown : when any key gets pressed, with keyCode

 *
 * The supplied widget can be any object implementing the following
 * methods:
 *   - function:nsIDOMNode insertItemAt(aIndex:number, aNode:nsIDOMNode,
 *                                      aValue:string)

 *
 * Optional methods that can be implemented by the widget:
 *   - function ensureElementIsVisible(aChild:nsIDOMNode)
 *
 * Optional attributes that may be handled (when calling
 * get/set/removeAttribute):
 *   - "emptyText": label temporarily added when there are no items present
 *   - "headerText": label permanently added as a header
 *
 * For automagical keyboard and mouse accessibility, the widget should be an
 * event emitter with the following events:

 * Gecko provides a list of both property names and their corresponding values.
 * We take out a list of matching selectors using the Inspector actor's
 * `getSuggestionsForQuery` method. Now the only thing is to parse the CSS being
 * edited by the user, figure out what token or word is being written and last
 * but the most difficult, what is being edited.
 *
 * The file 'css-parsing-utils' helps to convert the CSS into meaningful tokens,
 * each having a certain type associated with it. These tokens help us to figure
 * out the currently edited word and to write a CSS state machine to figure out
 * what the user is currently editing. By that, I mean, whether he is editing a
 * selector or a property or a value, or even fine grained information like an
 * id in the selector.
 *
 * The `resolveState` method iterated over the tokens spitted out by the
 * tokenizer, using switch cases, follows a state machine logic and finally
 * figures out these informations:
 *  - The state of the CSS at the cursor (one out of CSS_STATES)
 *  - The current token that is being edited `cmpleting`
 *  - If the state is "selector", the selector state (one of SELECTOR_STATES)
 *  - If the state is "selector", the current selector till the cursor
 *  - If the state is "value", the corresponding property name
 *
 * In case of "value" and "property" states, we simply use the information
 * provided by Gecko to filter out the possible suggestions.
 * For "selector" state, we request the Inspector actor to query the page DOM
 * and filter out the possible suggestions.
 * For "media" and "keyframes" state, the only possible suggestions for now are
 * "media" and "keyframes" respectively, although "media" can have suggestions
 * like "max-width", "orientation" etc. Similarly "value" state can also have
 * much better logical suggestions if we fine grain identify a sub state just
 * like we do for the "selector" state.

/**
 * The `edit` command opens the toolbox to the style editor, with a given
 * stylesheet open.
 *
 * This command is tricky. The 'edit' command uses the toolbox, so it's
 * clearly runAt:client, but it uses the 'resource' type which accesses the
 * DOM, so it must also be runAt:server.
 *
 * Our solution is to have the command technically be runAt:server, but to not
 * actually do anything other than basically `return args;`, and have the
 * converter (all converters are runAt:client) do the actual work of opening
 * a toolbox.
 *
 * For alternative solutions that we considered, see the comment on commit
 * 2645af7.

  /**
   * This module emits various events when state changes occur.  The basic event
   * naming scheme is that event "X" means "X has changed" or "X is available".
   * Some names are more detailed to clarify their precise meaning.
   *
   * The events this module may emit include:
   *   before-project:
   *     The selected project is about to change.  The event includes a special
   *     |cancel| callback that will abort the project change if desired.
   *   connection:
   *     The connection status has changed (connected, disconnected, etc.)
   *   project:
   *     The selected project has changed.
   *   project-started:
   *     The selected project started running on the connected runtime.
   *   project-stopped:
   *     The selected project stopped running on the connected runtime.
   *   project-removed:
   *     The selected project was removed from the project list.
   *   project-validated:
   *     The selected project just completed validation.  As part of validation,
   *     many pieces of metadata about the project are refreshed, including its
   *     name, manifest details, etc.
   *   runtime:
   *     The selected runtime has changed.
   *   runtime-global-actors:
   *     The list of global actors for the entire runtime (but not actors for a
   *     specific tab or app) are now available, so we can test for features
   *     like preferences and settings.
   *   runtime-details:
   *     The selected runtime's details have changed, such as its user-visible
   *     name.
   *   runtime-list:
   *     The list of available runtimes has changed, or any of the user-visible
   *     details (like names) for the non-selected runtimes has changed.
   *   runtime-telemetry:
   *     Detailed runtime telemetry has been recorded.  Used by tests.
   *   runtime-targets:
   *     The list of remote runtime targets available from the currently
   *     connected runtime (such as tabs or apps) has changed, or any of the
   *     user-visible details (like names) for the non-selected runtime targets
   *     has changed.  This event includes |type| in the details, to distinguish
   *     "apps" and "tabs".

/**
 * Runtime and Scanner API
 *
 * |RuntimeScanners| maintains a set of |Scanner| objects that produce one or
 * more |Runtime|s to connect to.  Add-ons can extend the set of known runtimes
 * by registering additional |Scanner|s that emit them.
 *
 * Each |Scanner| must support the following API:
 *
 * enable()
 *   Bind any event handlers and start any background work the scanner needs to
 *   maintain an updated set of |Runtime|s.
 *   Called when the first consumer (such as WebIDE) actively interested in
 *   maintaining the |Runtime| list enables the registry.
 * disable()
 *   Unbind any event handlers and stop any background work the scanner needs to
 *   maintain an updated set of |Runtime|s.
 *   Called when the last consumer (such as WebIDE) actively interested in
 *   maintaining the |Runtime| list disables the registry.
 * emits "runtime-list-updated"
 *   If the set of runtimes a |Scanner| manages has changed, it must emit this
 *   event to notify consumers of changes.
 * scan()
 *   Actively refreshes the list of runtimes the scanner knows about.  If your
 *   scanner uses an active scanning approach (as opposed to listening for
 *   events when changes occur), the bulk of the work would be done here.
 *   @return Promise
 *           Should be resolved when scanning is complete.  If scanning has no
 *           well-defined end point, you can resolve immediately, as long as
 *           update event is emitted later when changes are noticed.
 * listRuntimes()
 *   Return the current list of runtimes known to the |Scanner| instance.
 *   @return Iterable
 *
 * Each |Runtime| must support the following API:
 *
 * |type| field
 *   The |type| must be one of the values from the |RuntimeTypes| object.  This
 *   is used for Telemetry and to support displaying sets of |Runtime|s
 *   categorized by type.
 * |id| field
 *   An identifier that is unique in the set of all runtimes with the same
 *   |type|.  WebIDE tries to save the last used runtime via type + id, and
 *   tries to locate it again in the next session, so this value should attempt
 *   to be stable across Firefox sessions.
 * |name| field
 *   A user-visible label to identify the runtime that will be displayed in a
 *   runtime list.
 * |prolongedConnection| field
 *   A boolean value which should be |true| if the connection process is
 *   expected to take a unknown or large amount of time.  A UI may use this as a
 *   hint to skip timeouts or other time-based code paths.
 * connect()
 *   Configure the passed |connection| object with any settings need to
 *   successfully connect to the runtime, and call the |connection|'s connect()
 *   method.
 *   @param  Connection connection
 *           A |Connection| object from the DevTools |ConnectionManager|.
 *   @return Promise
 *           Resolved once you've called the |connection|'s connect() method.
 * configure() OPTIONAL
 *   Show a configuration screen if the runtime is configurable.

/**
 * The BoxModelHighlighter draws the box model regions on top of a node.
 * If the node is a block box, then each region will be displayed as 1 polygon.
 * If the node is an inline box though, each region may be represented by 1 or
 * more polygons, depending on how many line boxes the inline element has.
 *
 * Usage example:
 *
 * let h = new BoxModelHighlighter(env);
 * h.show(node, options);
 * h.hide();
 * h.destroy();
 *
 * Available options:
 * - region {String}
 *   "content", "padding", "border" or "margin"
 *   This specifies the region that the guides should outline.
 *   Defaults to "content"
 * - hideGuides {Boolean}
 *   Defaults to false
 * - hideInfoBar {Boolean}
 *   Defaults to false
 * - showOnly {String}
 *   "content", "padding", "border" or "margin"
 *   If set, only this region will be highlighted. Use with onlyRegionArea to
 *   only highlight the area of the region.
 * - onlyRegionArea {Boolean}
 *   This can be set to true to make each region's box only highlight the area
 *   of the corresponding region rather than the area of nested regions too.
 *   This is useful when used with showOnly.

/**
 * The ShapesHighlighter draws an outline shapes in the page.
 * The idea is to have something that is able to wrap complex shapes for css properties
 * such as shape-outside/inside, clip-path but also SVG elements.
 *
 * Notes on shape transformation:
 *
 * When using transform mode to translate, scale, and rotate shapes, a transformation
 * matrix keeps track of the transformations done to the original shape. When the
 * highlighter is toggled on/off or between transform mode and point editing mode,
 * the transformations applied to the shape become permanent.
 *
 * While transformations are being performed on a shape, there is an "original" and
 * a "transformed" coordinate system. This is used when scaling or rotating a rotated
 * shape.
 *
 * The "original" coordinate system is the one where (0,0) is at the top left corner
 * of the page, the x axis is horizontal, and the y axis is vertical.
 *
 * The "transformed" coordinate system is the one where (0,0) is at the top left
 * corner of the current shape. The x axis follows the north edge of the shape
 * (from the northwest corner to the northeast corner) and the y axis follows
 * the west edge of the shape (from the northwest corner to the southwest corner).
 *
 * Because of rotation, the "north" and "west" edges might not actually be at the
 * top and left of the transformed shape. Imagine that the compass directions are
 * also rotated along with the shape.
 *
 * A refresher for coordinates and change of basis that may be helpful:
 * https://www.math.ubc.ca/~behrend/math221/Coords.pdf

   * In addition, the cursor CSS property is applied to .shapes-root because if
   * it were attached to .shapes-marker, the cursor change no longer applies if
   * you are for example resizing the shape and your mouse goes off the point.
   * Also, if you are dragging a polygon point, the marker plays catch up to your

/**
 * Here's the server side of the remote inspector.
 *
 * The WalkerActor is the client's view of the debuggee's DOM.  It's gives
 * the client a tree of NodeActor objects.
 *
 * The walker presents the DOM tree mostly unmodified from the source DOM
 * tree, but with a few key differences:
 *
 *  - Empty text nodes are ignored.  This is pretty typical of developer
 *    tools, but maybe we should reconsider that on the server side.
 *  - iframes with documents loaded have the loaded document as the child,
 *    the walker provides one big tree for the whole document tree.
 *
 * There are a few ways to get references to NodeActors:
 *
 *   - When you first get a WalkerActor reference, it comes with a free
 *     reference to the root document's node.
 *   - Given a node, you can ask for children, siblings, and parents.
 *   - You can issue querySelector and querySelectorAll requests to find
 *     other elements.
 *   - Requests that return arbitrary nodes from the tree (like querySelector
 *     and querySelectorAll) will also return any nodes the client hasn't
 *     seen in order to have a complete set of parents.
 *
 * Once you have a NodeFront, you should be able to answer a few questions
 * without further round trips, like the node's name, namespace/tagName,
 * attributes, etc.  Other questions (like a text node's full nodeValue)
 * might require another round trip.
 *
 * The protocol guarantees that the client will always know the parent of
 * any node that is returned by the server.  This means that some requests
 * (like querySelector) will include the extra nodes needed to satisfy this
 * requirement.  The client keeps track of this parent relationship, so the
 * node fronts form a tree that is a subset of the actual DOM tree.
 *
 *
 * We maintain this guarantee to support the ability to release subtrees on
 * the client - when a node is disconnected from the DOM tree we want to be
 * able to free the client objects for all the children nodes.
 *
 * So to be able to answer "all the children of a given node that we have
 * seen on the client side", we guarantee that every time we've seen a node,
 * we connect it up through its parents.

/* Root actor for the remote debugging protocol. */

/**
 * Create a remote debugging protocol root actor.
 *
 * @param connection
 *     The DebuggerServerConnection whose root actor we are constructing.
 *
 * @param parameters
 *     The properties of |parameters| provide backing objects for the root
 *     actor's requests; if a given property is omitted from |parameters|, the
 *     root actor won't implement the corresponding requests or notifications.
 *     Supported properties:
 *
 *     - tabList: a live list (see below) of tab actors. If present, the
 *       new root actor supports the 'listTabs' request, providing the live
 *       list's elements as its tab actors, and sending 'tabListChanged'
 *       notifications when the live list's contents change. One actor in
 *       this list must have a true '.selected' property.
 *
 *     - addonList: a live list (see below) of addon actors. If present, the
 *       new root actor supports the 'listAddons' request, providing the live
 *       list's elements as its addon actors, and sending 'addonListchanged'
 *       notifications when the live list's contents change.
 *
 *     - globalActorFactories: an object |A| describing further actors to
 *       attach to the 'listTabs' reply. This is the type accumulated by
 *       DebuggerServer.addGlobalActor. For each own property |P| of |A|,
 *       the root actor adds a property named |P| to the 'listTabs'
 *       reply whose value is the name of an actor constructed by
 *       |A[P]|.
 *
 *     - onShutdown: a function to call when the root actor is destroyed.
 *
 * Instance properties:
 *
 * - applicationType: the string the root actor will include as the
 *      "applicationType" property in the greeting packet. By default, this
 *      is "browser".
 *
 * Live lists:
 *
 * A "live list", as used for the |tabList|, is an object that presents a
 * list of actors, and also notifies its clients of changes to the list. A
 * live list's interface is two properties:
 *
 * - getList: a method that returns a promise to the contents of the list.
 *
 * - onListChanged: a handler called, with no arguments, when the set of
 *             values the iterator would produce has changed since the last
 *             time 'iterator' was called. This may only be set to null or a
 *             callable value (one for which the typeof operator returns
 *             'function'). (Note that the live list will not call the
 *             onListChanged handler until the list has been iterated over
 *             once; if nobody's seen the list in the first place, nobody
 *             should care if its contents have changed!)
 *
 * When the list changes, the list implementation should ensure that any
 * actors yielded in previous iterations whose referents (tabs) still exist
 * get yielded again in subsequent iterations. If the underlying referent
 * is the same, the same actor should be presented for it.
 *
 * The root actor registers an 'onListChanged' handler on the appropriate
 * list when it may need to send the client 'tabListChanged' notifications,
 * and is careful to remove the handler whenever it does not need to send
 * such notifications (including when it is destroyed). This means that
 * live list implementations can use the state of the handler property (set
 * or null) to install and remove observers and event listeners.
 *
 * Note that, as the only way for the root actor to see the members of the
 * live list is to begin an iteration over the list, the live list need not
 * actually produce any actors until they are reached in the course of
 * iteration: alliterative lazy live lists.

/**
 * A SourceActor provides information about the source of a script. There
 * are two kinds of source actors: ones that represent real source objects,
 * and ones that represent non-existant "original" sources when the real
 * sources are sourcemapped. When a source is sourcemapped, actors are
 * created for both the "generated" and "original" sources, and the client will
 * only see the original sources. We separate these because there isn't
 * a 1:1 mapping of generated to original sources; one generated source
 * may represent N original sources, so we need to create N + 1 separate
 * actors.
 *
 * There are 4 different scenarios for sources that you should
 * understand:
 *
 * - A single non-sourcemapped source that is not inlined in HTML
 *   (separate JS file, eval'ed code, etc)
 * - A single sourcemapped source which creates N original sources
 * - An HTML page with multiple inline scripts, which are distinct
 *   sources, but should be represented as a single source
 * - A pretty-printed source (which may or may not be an original
 *   sourcemapped source), which generates a sourcemap for itself
 *
 * The complexity of `SourceActor` and `ThreadSources` are to handle
 * all of thise cases and hopefully internalize the complexities.
 *
 * @param Debugger.Source source
 *        The source object we are representing.
 * @param ThreadActor thread
 *        The current thread actor.
 * @param String originalUrl
 *        Optional. For sourcemapped urls, the original url this is representing.
 * @param Debugger.Source generatedSource
 *        Optional, passed in when aSourceMap is also passed in. The generated
 *        source object that introduced this source.
 * @param Boolean isInlineSource
 *        Optional. True if this is an inline source from a HTML or XUL page.
 * @param String contentType
 *        Optional. The content type of this source, if immediately available.

/**
 * Creates a TabActor whose main goal is to manage lifetime and
 * expose the tab actors being registered via DebuggerServer.registerModule.
 * But also track the lifetime of the document being tracked.
 *
 * ### Main requests:
 *
 * `attach`/`detach` requests:
 *  - start/stop document watching:
 *    Starts watching for new documents and emits `tabNavigated` and
 *    `frameUpdate` over RDP.
 *  - retrieve the thread actor:
 *    Instantiates a ThreadActor that can be later attached to in order to
 *    debug JS sources in the document.
 * `switchToFrame`:
 *  Change the targeted document of the whole TabActor, and its child tab actors
 *  to an iframe or back to its original document.
 *
 * Most of the TabActor properties (like `chromeEventHandler` or `docShells`)
 * are meant to be used by the various child tab actors.
 *
 * ### RDP events:
 *
 *  - `tabNavigated`:
 *    Sent when the tab is about to navigate or has just navigated to
 *    a different document.
 *    This event contains the following attributes:
 *     * url (string) The new URI being loaded.
 *     * nativeConsoleAPI (boolean) `false` if the console API of the page has
 *                                          been overridden (e.g. by Firebug),
 *                                  `true`  if the Gecko implementation is used.
 *     * state (string) `start` if we just start requesting the new URL,
 *                      `stop`  if the new URL is done loading.
 *     * isFrameSwitching (boolean) Indicates the event is dispatched when
 *                                  switching the TabActor context to
 *                                  a different frame. When we switch to
 *                                  an iframe, there is no document load.
 *                                  The targeted document is most likely
 *                                  going to be already done loading.
 *     * title (string) The document title being loaded.
 *                      (sent only on state=stop)
 *
 *  - `frameUpdate`:
 *    Sent when there was a change in the child frames contained in the document
 *    or when the tab's context was switched to another frame.
 *    This event can have four different forms depending on the type of change:
 *    * One or many frames are updated:
 *      { frames: [{ id, url, title, parentID }, ...] }
 *    * One frame got destroyed:
 *      { frames: [{ id, destroy: true }]}
 *    * All frames got destroyed:
 *      { destroyAll: true }
 *    * We switched the context of the TabActor to a specific frame:
 *      { selected: #id }
 *
 * ### Internal, non-rdp events:
 * Various events are also dispatched on the TabActor itself that are not
 * related to RDP, so, not sent to the client. They all relate to the documents
 * tracked by the TabActor (its main targeted document, but also any of its
 * iframes).
 *  - will-navigate
 *    This event fires once navigation starts.
 *    All pending user prompts are dealt with,
 *    but it is fired before the first request starts.
 *  - navigate
 *    This event is fired once the document's readyState is "complete".
 *  - window-ready
 *    This event is fired in various distinct scenarios:
 *     * When a new Window object is crafted, equivalent of `DOMWindowCreated`.
 *       It is dispatched before any page script is executed.
 *     * We will have already received a window-ready event for this window
 *       when it was created, but we received a window-destroyed event when
 *       it was frozen into the bfcache, and now the user navigated back to
 *       this page, so it's now live again and we should resume handling it.
 *     * For each existing document, when an `attach` request is received.
 *       At this point scripts in the page will be already loaded.
 *     * When `swapFrameLoaders` is used, such as with moving tabs between
 *       windows or toggling Responsive Design Mode.
 *  - window-destroyed
 *    This event is fired in two cases:
 *     * When the window object is destroyed, i.e. when the related document
 *       is garbage collected. This can happen when the tab is closed or the
 *       iframe is removed from the DOM.
 *       It is equivalent of `inner-window-destroyed` event.
 *     * When the page goes into the bfcache and gets frozen.
 *       The equivalent of `pagehide`.
 *  - changed-toplevel-document
 *    This event fires when we switch the TabActor targeted document
 *    to one of its iframes, or back to its original top document.
 *    It is dispatched between window-destroyed and window-ready.
 *  - stylesheet-added
 *    This event is fired when a StyleSheetActor is created.
 *    It contains the following attribute :
 *     * actor (StyleSheetActor) The created actor.
 *
 * Note that *all* these events are dispatched in the following order
 * when we switch the context of the TabActor to a given iframe:
 *  - will-navigate
 *  - window-destroyed
 *  - changed-toplevel-document
 *  - window-ready
 *  - navigate
 *
 * This class is subclassed by ContentActor and others.
 * Subclasses are expected to implement a getter for the docShell property.
 *
 * @param connection DebuggerServerConnection
 *        The conection to the client.

/**
 * Multiple actors that use a |Debugger| instance come in a few versions, each
 * with a different set of debuggees. One version for content tabs (globals
 * within a tab), one version for chrome debugging (all globals), and sometimes
 * a third version for addon debugging (chrome globals the addon is loaded in
 * and content globals the addon injects scripts into). The |makeDebugger|
 * function helps us avoid repeating the logic for finding and maintaining the
 * correct set of globals for a given |Debugger| instance across each version of
 * all of our actors.
 *
 * The |makeDebugger| function expects a single object parameter with the
 * following properties:
 *
 * @param Function findDebuggees
 *        Called with one argument: a |Debugger| instance. This function should
 *        return an iterable of globals to be added to the |Debugger|
 *        instance. The globals may be wrapped in a |Debugger.Object|, or
 *        unwrapped.
 *
 * @param Function shouldAddNewGlobalAsDebuggee
 *        Called with one argument: a |Debugger.Object| wrapping a global
 *        object. This function must return |true| if the global object should
 *        be added as debuggee, and |false| otherwise.
 *
 * @returns Debugger
 *          Returns a |Debugger| instance that can manage its set of debuggee
 *          globals itself and is decorated with the |EventEmitter| class.
 *
 *          Events emitted by the returned |Debugger| instance:
 *
 *            - "newGlobal": Emitted when a new global has been added as a
 *               debuggee. Passes the |Debugger.Object| wrapping the new
 *               debuggee global to listeners.
 *
 *          Existing |Debugger| properties set on the returned |Debugger|
 *          instance:
 *
 *            - onNewGlobalObject: The |Debugger| will automatically add new
 *              globals as debuggees if calling |shouldAddNewGlobalAsDebuggee|
 *              with the global returns true.
 *
 *            - uncaughtExceptionHook: The |Debugger| already has an error
 *              reporter attached to |uncaughtExceptionHook|, so if any
 *              |Debugger| hooks fail, the error will be reported.
 *
 *          New properties set on the returned |Debugger| instance:
 *
 *            - addDebuggees: A function which takes no arguments. It adds all
 *              current globals that should be debuggees (as determined by
 *              |findDebuggees|) to the |Debugger| instance.

 *
 * This object also takes care of listening for TabClose events and
 * onCloseWindow notifications, and exiting the BrowserTabActors concerned.
 *
 * (See the documentation for RootActor for the definition of the "live
 * list" interface.)
 *
 * @param connection DebuggerServerConnection
 *     The connection in which this list's tab actors may participate.
 *
 * Some notes:
 *
 * This constructor is specific to the desktop browser environment; it
 * maintains the tab list by tracking XUL windows and their XUL documents'
 * "tabbrowser", "tab", and "browser" elements. What's entailed in maintaining
 * an accurate list of open tabs in this context?
 *
 * - Opening and closing XUL windows:
 *
 * An nsIWindowMediatorListener is notified when new XUL windows (i.e., desktop
 * windows) are opened and closed. It is not notified of individual content
 * browser tabs coming and going within such a XUL window. That seems
 * reasonable enough; it's concerned with XUL windows, not tab elements in the
 * window's XUL document.
 *
 * However, even if we attach TabOpen and TabClose event listeners to each XUL
 * window as soon as it is created:
 *
 * - we do not receive a TabOpen event for the initial empty tab of a new XUL
 *   window; and
 *
 * - we do not receive TabClose events for the tabs of a XUL window that has
 *   been closed.
 *
 * This means that TabOpen and TabClose events alone are not sufficient to
 * maintain an accurate list of live tabs and mark tab actors as closed
 * promptly. Our nsIWindowMediatorListener onCloseWindow handler must find and
 * exit all actors for tabs that were in the closing window.
 *
 * Since this is a bit hairy, we don't make each individual attached tab actor
 * responsible for noticing when it has been closed; we watch for that, and
 * promise to call each actor's 'exit' method when it's closed, regardless of
 * how we learn the news.
 *
 * - nsIWindowMediator locks
 *
 * nsIWindowMediator holds a lock protecting its list of top-level windows
 * while it calls nsIWindowMediatorListener methods. nsIWindowMediator's
 * GetEnumerator method also tries to acquire that lock. Thus, enumerating
 * windows from within a listener method deadlocks (bug 873589). Rah. One
 * can sometimes work around this by leaving the enumeration for a later
 * tick.
 *
 * - Dragging tabs between windows:
 *
 * When a tab is dragged from one desktop window to another, we receive a
 * TabOpen event for the new tab, and a TabClose event for the old tab; tab XUL
 * elements do not really move from one document to the other (although their
 * linked browser's content window objects do).

 * belong to the closing XUL window, rather than trying to somehow track which
 * XUL window each tab belongs to.
 *
 * - Title changes:
 *
 * For tabs living in the child process, we listen for DOMTitleChange message
 * via the top-level window's message manager. Doing this also allows listening
 * for title changes on Fennec.
 * But as these messages aren't sent for tabs loaded in the parent process,

  /**
   * Evaluates a string using the debugger API.
   *
   * To allow the variables view to update properties from the Web Console we
   * provide the "bindObjectActor" mechanism: the Web Console tells the
   * ObjectActor ID for which it desires to evaluate an expression. The
   * Debugger.Object pointed at by the actor ID is bound such that it is
   * available during expression evaluation (executeInGlobalWithBindings()).
   *
   * Example:
   *   _self['foobar'] = 'test'
   * where |_self| refers to the desired object.
   *
   * The |frameActor| property allows the Web Console client to provide the
   * frame actor ID, such that the expression can be evaluated in the
   * user-selected stack frame.
   *
   * For the above to work we need the debugger and the Web Console to share
   * a connection, otherwise the Web Console actor will not find the frame
   * actor.
   *
   * The Debugger.Frame comes from the jsdebugger's Debugger instance, which
   * is different from the Web Console's Debugger instance. This means that
   * for evaluation to work, we need to create a new instance for the Web
   * Console Commands helpers - they need to be Debugger.Objects coming from the
   * jsdebugger's Debugger instance.
   *
   * When |bindObjectActor| is used objects can come from different iframes,
   * from different domains. To avoid permission-related errors when objects
   * come from a different window, we also determine the object's own global,
   * such that evaluation happens in the context of that global. This means that
   * evaluation will happen in the object's iframe, rather than the top level
   * window.
   *
   * @param string string
   *        String to evaluate.
   * @param object [options]
   *        Options for evaluation:
   *        - bindObjectActor: the ObjectActor ID to use for evaluation.
   *          |evalWithBindings()| will be called with one additional binding:
   *          |_self| which will point to the Debugger.Object of the given
   *          ObjectActor.
   *        - selectedObjectActor: Like bindObjectActor, but executes with the
   *          top level window as the global.
   *        - frameActor: the FrameActor ID to use for evaluation. The given
   *        debugger frame is used for evaluation, instead of the global window.
   *        - selectedNodeActor: the NodeActor ID of the currently selected node
   *        in the Inspector (or null, if there is no selection). This is used
   *        for helper functions that make reference to the currently selected
   *        node, like $0.
   *         - url: the url to evaluate the script as. Defaults to
   *         "debugger eval code".
   * @return object
   *         An object that holds the following properties:
   *         - dbg: the debugger where the string was evaluated.
   *         - frame: (optional) the frame where the string was evaluated.
   *         - window: the Debugger.Object for the global where the string was
   *         evaluated.
   *         - result: the result of the evaluation.
   *         - helperResult: any result coming from a Web Console commands
   *         function.

 * Creates a TabActor for debugging all the contexts associated to a target WebExtensions

 * Most of the implementation is inherited from ChromeActor (which inherits most of its
 * implementation from TabActor).
 * WebExtensionChildActor is created by a WebExtensionParentActor counterpart, when its
 * parent actor's `connect` method has been called (on the listAddons RDP package),
 * it runs in the same process that the extension is running into (which can be the main
 * process if the extension is running in non-oop mode, or the child extension process
 * if the extension is running in oop-mode).
 *
 * A WebExtensionChildActor contains all tab actors, like a regular ChromeActor
 * or TabActor.
 *
 * History lecture:
 * - The add-on actors used to not inherit TabActor because of the different way the
 * add-on APIs where exposed to the add-on itself, and for this reason the Addon Debugger
 * has only a sub-set of the feature available in the Tab or in the Browser Toolbox.
 * - In a WebExtensions add-on all the provided contexts (background, popups etc.),
 * besides the Content Scripts which run in the content process, hooked to an existent
 * tab, by creating a new WebExtensionActor which inherits from ChromeActor, we can
 * provide a full features Addon Toolbox (which is basically like a BrowserToolbox which
 * filters the visible sources and frames to the one that are related to the target
 * add-on).
 * - When the WebExtensions OOP mode has been introduced, this actor has been refactored
 * and moved from the main process to the new child extension process.

/*
 * About the objects defined in this file:
 * - CssLogic contains style information about a view context. It provides
 *   access to 2 sets of objects: Css[Sheet|Rule|Selector] provide access to
 *   information that does not change when the selected element changes while
 *   Css[Property|Selector]Info provide information that is dependent on the
 *   selected element.
 *   Its key methods are highlight(), getPropertyInfo() and forEachSheet(), etc
 *
 * - CssSheet provides a more useful API to a DOM CSSSheet for our purposes,
 *   including shortSource and href.
 * - CssRule a more useful API to a DOM CSSRule including access to the group
 *   of CssSelectors that the rule provides properties for
 * - CssSelector A single selector - i.e. not a selector group. In other words
 *   a CssSelector does not contain ','. This terminology is different from the
 *   standard DOM API, but more inline with the definition in the spec.
 *
 * - CssPropertyInfo contains style information for a single property for the
 *   highlighted element.
 * - CssSelectorInfo is a wrapper around CssSelector, which adds sorting with
 *   reference to the selected element.

   *

   *        deprecated and will result in eagerly loading the actor module
   *        with the memory overhead that entails.
   *        An object with 3 mandatory attributes:
   *        - prefix (string):
   *          The prefix of an actor is used to compute:

   *            (See ActorPool.addActor)
   *          - the actor name in the listTabs request. Sending a listTabs
   *            request to the root actor returns actor IDs. IDs are in
   *            dictionaries, with actor names as keys and actor IDs as values.
   *            The actor name is the prefix to which the "Actor" string is
   *            appended. So for an actor with the `console` prefix, the actor
   *            name will be `consoleActor`.
   *        - constructor (string):
   *          the name of the exported symbol to be used as the actor
   *          constructor.
   *        - type (a dictionary of booleans with following attribute names):
   *          - "global"
   *            registers a global actor instance, if true.
   *            A global actor has the root actor as its parent.
   *          - "tab"
   *            registers a tab actor instance, if true.
   *            A new actor will be created for each tab and each app.

// easy to recognize.

// The `beforeExpr` property is used to disambiguate between regular
// expressions and divisions. It is set on all token types that can
// be followed by an expression (thus, a slash after them would be a
// regular expression).

// The `startsExpr` property is used to check if the token ends a
// `yield` expression. It is set on all token types that either can
// directly start an expression (like a quotation mark) or can
// continue an expression (like the body of a string).
//

// to know when parsing a label, in order to allow or disallow
// continue jumps to that label.

// Acorn: Loose parser
//
// This module provides an alternative parser (`parse_dammit`) that
// exposes that same interface as `parse`, but will try to parse
// anything as JavaScript, repairing syntax error the best it can.
// There are circumstances in which it will raise an error and give
// up, but they are very rare. The resulting AST will be a mostly
// valid JavaScript AST (as per the [Mozilla parser API][api], except
// that:
//
// - Return outside functions is allowed
//
// - Label consistency (no conflicts, break only to existing labels)
//   is not enforced.
//
// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
//   the parser got too confused to return anything meaningful.
//
// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
//
// The expected use for this is to *first* try `acorn.parse`, and only
// if that fails switch to `parse_dammit`. The loose parser might
// parse badly indented code incorrectly, so **don't** use it as
// your default parser.
//
// Quite a lot of acorn.js is duplicated here. The alternative was to
// add a *lot* of extra cruft to that file, making it less readable
// and slower. Copying and editing the code allowed me to make
// invasive changes and simplifications without creating a complicated
// tangle.

 *
 * Adapted from https://github.com/mozilla-b2g/gaia/blob/f09993563fb5fec4393eb71816ce76cb00463190/shared/js/async_storage.js
 * (converted to use Promises instead of callbacks).
 *
 * This file defines an asynchronous version of the localStorage API, backed by
 * an IndexedDB database.  It creates a global asyncStorage object that has
 * methods like the localStorage object.
 *
 * To store a value use setItem:
 *
 *   asyncStorage.setItem("key", "value");
 *
 * This returns a promise in case you want confirmation that the value has been stored.
 *
 *  asyncStorage.setItem("key", "newvalue").then(function() {
 *    console.log("new value stored");
 *  });
 *
 * To read a value, call getItem(), but note that you must wait for a promise
 * resolution for the value to be retrieved.
 *
 *  asyncStorage.getItem("key").then(function(value) {
 *    console.log("The value of key is:", value);
 *  });
 *
 * Note that unlike localStorage, asyncStorage does not allow you to store and
 * retrieve values by setting and querying properties directly. You cannot just
 * write asyncStorage.key; you have to explicitly call setItem() or getItem().
 *
 * removeItem(), clear(), length(), and key() are like the same-named methods of
 * localStorage, and all return a promise.
 *
 * The asynchronous nature of getItem() makes it tricky to retrieve multiple
 * values. But unlike localStorage, asyncStorage does not require the values you
 * store to be strings.  So if you need to save multiple values and want to
 * retrieve them together, in a single asynchronous operation, just group the
 * values into a single object. The properties of this object may not include
 * DOM elements, but they may include things like Blobs and typed arrays.

/**
 * Connection Manager.
 *
 * To use this module:
 * const {ConnectionManager} = require("devtools/shared/client/connection-manager");
 *
 * # ConnectionManager
 *
 * Methods:
 *  . Connection createConnection(host, port)
 *  . void       destroyConnection(connection)
 *  . Number     getFreeTCPPort()
 *
 * Properties:
 *  . Array      connections
 *
 * # Connection
 *
 * A connection is a wrapper around a debugger client. It has a simple
 * API to instantiate a connection to a debugger server. Once disconnected,
 * no need to re-create a Connection object. Calling `connect()` again
 * will re-create a debugger client.
 *
 * Methods:
 *  . connect()             Connect to host:port. Expect a "connecting" event.
 *                          If no host is not specified, a local pipe is used
 *  . connect(transport)    Connect via transport. Expect a "connecting" event.
 *  . disconnect()          Disconnect if connected. Expect a "disconnecting" event
 *
 * Properties:
 *  . host                  IP address or hostname
 *  . port                  Port
 *  . logs                  Current logs. "newlog" event notifies new available logs
 *  . store                 Reference to a local data store (see below)
 *  . keepConnecting        Should the connection keep trying to connect?
 *  . timeoutDelay          When should we give up (in ms)?
 *                          0 means wait forever.
 *  . encryption            Should the connection be encrypted?
 *  . authentication        What authentication scheme should be used?
 *  . authenticator         The |Authenticator| instance used.  Overriding
 *                          properties of this instance may be useful to
 *                          customize authentication UX for a specific use case.
 *  . advertisement         The server's advertisement if found by discovery
 *  . status                Connection status:
 *                            Connection.Status.CONNECTED
 *                            Connection.Status.DISCONNECTED
 *                            Connection.Status.CONNECTING
 *                            Connection.Status.DISCONNECTING
 *                            Connection.Status.DESTROYED
 *
 * Events (as in event-emitter.js):
 *  . Connection.Events.CONNECTING      Trying to connect to host:port
 *  . Connection.Events.CONNECTED       Connection is successful
 *  . Connection.Events.DISCONNECTING   Trying to disconnect from server
 *  . Connection.Events.DISCONNECTED    Disconnected (at client request,
 *                                      or because of a timeout or connection error)
 *  . Connection.Events.STATUS_CHANGED  The connection status (connection.status)
 *                                      has changed
 *  . Connection.Events.TIMEOUT         Connection timeout
 *  . Connection.Events.HOST_CHANGED    Host has changed
 *  . Connection.Events.PORT_CHANGED    Port has changed
 *  . Connection.Events.NEW_LOG         A new log line is available
 *

   * Transmit streaming data via a bulk request.
   *
   * This method initiates the bulk send process by queuing up the header data.
   * The caller receives eventual access to a stream for writing.
   *
   * Since this opens up more options for how the server might respond (it could
   * send back either JSON or bulk data), and the returned Request object emits
   * events for different stages of the request process that you may want to
   * react to.
   *
   * @param request Object
   *        This is modeled after the format of JSON packets above, but does not
   *        actually contain the data, but is instead just a routing header:
   *          * actor:  Name of actor that will receive the packet
   *          * type:   Name of actor's method that should be called on receipt
   *          * length: Size of the data to be sent
   * @return Request
   *         This object emits a number of events to allow you to respond to
   *         different parts of the request lifecycle.
   *
   *         Events emitted:
   *         * bulk-send-ready: Ready to send bulk data to the server, using the
   *           event data object containing:
   *           * stream:   This output stream should only be used directly if
   *                       you can ensure that you will write exactly |length|
   *                       bytes and will not close the stream when writing is
   *                       complete
   *           * done:     If you use the stream directly (instead of |copyFrom|

 * This implements a UDP mulitcast device discovery protocol that:
 *   * Is optimized for mobile devices
 *   * Doesn't require any special schema for service info
 *
 * To ensure it works well on mobile devices, there is no heartbeat or other
 * recurring transmission.
 *
 * Devices are typically in one of two groups: scanning for services or
 * providing services (though they may be in both groups as well).
 *
 * Scanning devices listen on UPDATE_PORT for UDP multicast traffic.  When the
 * scanning device wants to force an update of the services available, it sends
 * a status packet to SCAN_PORT.
 *
 * Service provider devices listen on SCAN_PORT for any packets from scanning
 * devices.  If one is recevied, the provider device sends a status packet
 * (listing the services it offers) to UPDATE_PORT.
 *
 * Scanning devices purge any previously known devices after REPLY_TIMEOUT ms
 * from that start of a scan if no reply is received during the most recent
 * scan.
 *
 * When a service is registered, is supplies a regular object with any details
 * about itself (a port number, for example) in a service-defined format, which
 * is then available to scanning devices.

 * This term is used because carries the notion of a work-flow, or process to
 * getting the information to execute a command correct.
 * There is little point in a requisition for parameter-less commands because
 * there is no information to collect. A Requisition is a collection of
 * assignments of values to parameters, each handled by an instance of
 * Assignment.
 *
 * @param system Allows access to the various plug-in points in GCLI. At a
 * minimum it must contain commands and types objects.
 * @param options A set of options to customize how GCLI is used. Includes:
 * - environment An optional opaque object passed to commands in the
 *   Execution Context.
 * - document A DOM Document passed to commands using the Execution Context in
 *   order to allow creation of DOM nodes. If missing Requisition will use the
 *   global 'document', or leave undefined.
 * - commandOutputManager A custom commandOutputManager to which output should
 *   be sent
 * @constructor

 * So we have to do something fancy to get the sharing but not mess up the web.
 *
 * This file requires 'gcli/types/fileparser', and there are 4 implementations

 * - '/lib/gcli/types/fileparser.js', the default web version that uses XHR to
 *   talk to the node server
 * - '/lib/server/gcli/types/fileparser.js', an NodeJS stub, and ...
 * - '/mozilla/gcli/types/fileparser.js', the Firefox implementation both of
 *   these are shims which import
 * - 'gcli/util/fileparser', does the real work, except the actual file access
 *
 * The file access comes from the 'gcli/util/filesystem' module, and there are
 * 2 implementations of this:

 * A selection allows the user to pick a value from known set of options.
 * An option is made up of a name (which is what the user types) and a value
 * (which is passed to exec)
 * @param typeSpec Object containing properties that describe how this
 * selection functions. Properties include:
 * - lookup: An array of objects, one for each option, which contain name and
 *   value properties. lookup can be a function which returns this array
 * - data: An array of strings - alternative to 'lookup' where the valid values
 *   are strings. i.e. there is no mapping between what is typed and the value
 *   that is used by the program
 * - stringifyProperty: Conversion from value to string is generally a process
 *   of looking through all the valid options for a matching value, and using
 *   the associated name. However the name maybe available directly from the
 *   value using a property lookup. Setting 'stringifyProperty' allows
 *   SelectionType to take this shortcut.
 * - cacheable: If lookup is a function, then we normally assume that
 *   the values fetched can change. Setting 'cacheable:true' enables internal
 *   caching.

 *   Its key methods are highlight(), getPropertyInfo() and forEachSheet(), etc

 *
 * - CssSheet provides a more useful API to a DOM CSSSheet for our purposes,
 *   including shortSource and href.
 * - CssRule a more useful API to a DOM CSSRule including access to the group
 *   of CssSelectors that the rule provides properties for
 * - CssSelector A single selector - i.e. not a selector group. In other words

 CSS Beautifier
---------------

    Written by Harutyun Amirjanyan, ([email protected])

    Based on code initially developed by: Einar Lielmanis, <[email protected]>
        http://jsbeautifier.org/

    Usage:
        css_beautify(source_text);
        css_beautify(source_text, options);

    The options are (default in brackets):
        indent_size (4)                   — indentation size,
        indent_char (space)               — character to indent with,
        selector_separator_newline (true) - separate selectors with newline or
                                            not (e.g. "a,\nbr" or "a, br")
        end_with_newline (false)          - end with a newline

    e.g

    css_beautify(css_source_text, {
      'indent_size': 1,
      'indent_char': '\t',
      'selector_separator': ' ',
      'end_with_newline': false,

 Style HTML
---------------

  Written by Nochum Sossonko, ([email protected])

  Based on code initially developed by: Einar Lielmanis, <[email protected]>
    http://jsbeautifier.org/

  Usage:
    style_html(html_source);

    style_html(html_source, options);

  The options are:
    indent_inner_html (default false)  — indent <head> and <body> sections,
    indent_size (default 4)          — indentation size,
    indent_char (default space)      — character to indent with,
    wrap_line_length (default 250)            -  maximum amount of characters per line (0 = disable)
    brace_style (default "collapse") - "collapse" | "expand" | "end-expand"
            put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line.
    unformatted (defaults to inline tags) - list of tags, that shouldn't be reformatted
    indent_scripts (default normal)  - "keep"|"separate"|"normal"
    preserve_newlines (default true) - whether existing line breaks before elements should be preserved
                                        Only works before elements, not inside tags or for text.
    max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk
    indent_handlebars (default false) - format and indent {{#foo}} and {{/foo}}

    e.g.

    style_html(html_source, {
      'indent_inner_html': false,
      'indent_size': 2,
      'indent_char': ' ',
      'wrap_line_length': 78,
      'brace_style': 'expand',
      'unformatted': ['a', 'sub', 'sup', 'b', 'i', 'u'],
      'preserve_newlines': true,
      'max_preserve_newlines': 5,
      'indent_handlebars': false
    });

 JS Beautifier
---------------


  Written by Einar Lielmanis, <[email protected]>
      http://jsbeautifier.org/

  Originally converted to javascript by Vital, <[email protected]>
  "End braces on own line" added by Chris J. Shull, <[email protected]>
  Parsing improvements for brace-less statements by Liam Newman <[email protected]>


  Usage:
    js_beautify(js_source_text);
    js_beautify(js_source_text, options);

  The options are:
    indent_size (default 4)          - indentation size,
    indent_char (default space)      - character to indent with,
    preserve_newlines (default true) - whether existing line breaks should be preserved,
    max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk,

    jslint_happy (default false) - if true, then jslint-stricter mode is enforced.

            jslint_happy       !jslint_happy
            ---------------------------------
            function ()        function()

    brace_style (default "collapse") - "collapse" | "expand" | "end-expand"
            put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line.

    space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)",

    unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65"

    wrap_line_length (default unlimited) - lines should wrap at next opportunity after this number of characters.
          NOTE: This is not a hard limit. Lines will continue until a point where a newline would
                be preserved if it were present.

    e.g

    js_beautify(js_source_text, {
      'indent_size': 1,
      'indent_char': '\t'
    });

// Here we introduce new require contexts for each possible locale
// directory.  Then we use the correct context to load the property

 * A helper class to deduplicate old-version profiles.

 * The main functionality provided is deduplicating frames and stacks.
 *
 * For example, given 2 stacks
 *   [A, B, C]
 * and
 *   [A, B, D]
 *
 * There are 4 unique frames: A, B, C, and D.
 * There are 4 unique prefixes: [A], [A, B], [A, B, C], [A, B, D]
 *
 * For the example, the output of using UniqueStacks is:
 *
 * Frame table:
 *   [A, B, C, D]
 *
 * That is, A has id 0, B has id 1, etc.
 *
 * Since stack prefixes are themselves deduplicated (shared), stacks are
 * represented as a tree, or more concretely, a pair of ids, the prefix and
 * the leaf.
 *
 * Stack table:
 *   [
 *     [null, 0],
 *     [0,    1],
 *     [1,    2],
 *     [1,    3]
 *   ]
 *
 * That is, [A] has id 0 and value [null, 0]. This means it has no prefix, and
 * has the leaf frame 0, which resolves to A in the frame table.
 *
 * [A, B] has id 1 and value [0, 1]. This means it has prefix 0, which is [A],
 * and leaf 1, thus [A, B].
 *
 * [A, B, C] has id 2 and value [1, 2]. This means it has prefix 1, which in
 * turn is [A, B], and leaf 2, thus [A, B, C].
 *
 * [A, B, D] has id 3 and value [1, 3]. Note how it shares the prefix 1 with
 * [A, B, C].

	/**
	 * An IndexedSourceMapConsumer instance represents a parsed source map which
	 * we can query for information. It differs from BasicSourceMapConsumer in
	 * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
	 * input.
	 *
	 * The first parameter is a raw source map (either as a JSON string, or already
	 * parsed to an object). According to the spec for indexed source maps, they
	 * have the following attributes:
	 *
	 *   - version: Which version of the source map spec this map is following.
	 *   - file: Optional. The generated file this source map is associated with.
	 *   - sections: A list of section definitions.
	 *
	 * Each value under the "sections" field has two fields:
	 *   - offset: The offset into the original specified at which this section
	 *       begins to apply, defined as an object with a "line" and "column"
	 *       field.
	 *   - map: A source map definition. This source map could also be indexed,
	 *       but doesn't have to be.
	 *
	 * Instead of the "map" field, it's also possible to have a "url" field
	 * specifying a URL to retrieve a source map from, but that's currently
	 * unsupported.
	 *
	 * Here's an example source map, taken from the source map spec[0], but
	 * modified to omit a section which uses the "url" field.
	 *
	 *  {
	 *    version : 3,
	 *    file: "app.js",
	 *    sections: [{
	 *      offset: {line:100, column:10},
	 *      map: {
	 *        version : 3,
	 *        file: "section.js",
	 *        sources: ["foo.js", "bar.js"],
	 *        names: ["src", "maps", "are", "fun"],
	 *        mappings: "AAAA,E;;ABCDE;"
	 *      }
	 *    }],
	 *  }
	 *
	 * The second parameter, if given, is a string whose value is the URL
	 * at which the source map was found.  This URL is used to compute the
	 * sources array.
	 *
	 * [0]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit#heading=h.535es3xeprgt

/**
 * This module implements a subset of "Task.js" <http://taskjs.org/>.
 * It is a copy of toolkit/modules/Task.jsm.  Please try not to
 * diverge the API here.
 *
 * Paraphrasing from the Task.js site, tasks make sequential, asynchronous
 * operations simple, using the power of JavaScript's "yield" operator.
 *
 * Tasks are built upon generator functions and promises, documented here:
 *
 * <https://developer.mozilla.org/en/JavaScript/Guide/Iterators_and_Generators>
 * <http://wiki.commonjs.org/wiki/Promises/A>
 *
 * The "Task.spawn" function takes a generator function and starts running it as
 * a task.  Every time the task yields a promise, it waits until the promise is
 * fulfilled.  "Task.spawn" returns a promise that is resolved when the task
 * completes successfully, or is rejected if an exception occurs.
 *
 * -----------------------------------------------------------------------------
 *
 * const {Task} = require("devtools/shared/task");
 *
 * Task.spawn(function* () {
 *
 *   // This is our task. Let's create a promise object, wait on it and capture
 *   // its resolution value.
 *   let myPromise = getPromiseResolvedOnTimeoutWithValue(1000, "Value");
 *   let result = yield myPromise;
 *
 *   // This part is executed only after the promise above is fulfilled (after
 *   // one second, in this imaginary example).  We can easily loop while
 *   // calling asynchronous functions, and wait multiple times.
 *   for (let i = 0; i < 3; i++) {
 *     result += yield getPromiseResolvedOnTimeoutWithValue(50, "!");
 *   }
 *
 *   return "Resolution result for the task: " + result;
 * }).then(function (result) {
 *
 *   // result == "Resolution result for the task: Value!!!"
 *
 *   // The result is undefined if no value was returned.
 *
 * }, function (exception) {
 *
 *   // Failure!  We can inspect or report the exception.
 *
 * });
 *
 * -----------------------------------------------------------------------------
 *
 * This module implements only the "Task.js" interfaces described above, with no
 * additional features to control the task externally, or do custom scheduling.
 * It also provides the following extensions that simplify task usage in the
 * most common cases:
 *
 * - The "Task.spawn" function also accepts an iterator returned by a generator
 *   function, in addition to a generator function.  This way, you can call into
 *   the generator function with the parameters you want, and with "this" bound
 *   to the correct value.  Also, "this" is never bound to the task object when
 *   "Task.spawn" calls the generator function.
 *
 * - In addition to a promise object, a task can yield the iterator returned by
 *   a generator function.  The iterator is turned into a task automatically.
 *   This reduces the syntax overhead of calling "Task.spawn" explicitly when
 *   you want to recurse into other task functions.
 *
 * - The "Task.spawn" function also accepts a primitive value, or a function
 *   returning a primitive value, and treats the value as the result of the
 *   task.  This makes it possible to call an externally provided function and
 *   spawn a task from it, regardless of whether it is an asynchronous generator
 *   or a synchronous function.  This comes in handy when iterating over
 *   function lists where some items have been converted to tasks and some not.

   * arguments, and it requires the task to be a function.
   *
   * It simplifies the common pattern of implementing a method via a task,
   * like this simple object with a 'greet' method that has a 'name' parameter
   * and spawns a task to send a greeting and return its reply:

   *     }).bind(this);
   *   })
   * };
   *
   * With Task.async, the method can be declared succinctly:
   *
   * let greeter = {
   *   message: "Hello, NAME!",
   *   greet: Task.async(function* (name) {
   *     return yield sendGreeting(this.message.replace(/NAME/, name));
   *   })
   * };
   *
   * While maintaining identical semantics:
   *
   * greeter.greet("Mitchell").then((reply) => { ... }); // behaves the same
   *

/**
 * This helper function (and its companion object) are used by bulk senders and
 * receivers to read and write data in and out of other streams.  Functions that
 * make use of this tool are passed to callers when it is time to read or write
 * bulk data.  It is highly recommended to use these copier functions instead of
 * the stream directly because the copier enforces the agreed upon length.
 * Since bulk mode reuses an existing stream, the sender and receiver must write
 * and read exactly the agreed upon amount of data, or else the entire transport
 * will be left in a invalid state.  Additionally, other methods of stream
 * copying (such as NetUtil.asyncCopy) close the streams involved, which would
 * terminate the debugging transport, and so it is avoided here.
 *
 * Overall, this *works*, but clearly the optimal solution would be able to just
 * use the streams directly.  If it were possible to fully implement
 * nsIInputStream / nsIOutputStream in JS, wrapper streams could be created to
 * enforce the length and avoid closing, and consumers could use familiar stream
 * utilities like NetUtil.asyncCopy.
 *
 * The function takes two async streams and copies a precise number of bytes
 * from one to the other.  Copying begins immediately, but may complete at some
 * future time depending on data size.  Use the returned promise to know when
 * it's complete.
 *
 * @param input nsIAsyncInputStream
 *        The stream to copy from.
 * @param output nsIAsyncOutputStream
 *        The stream to copy to.
 * @param length Integer
 *        The amount of data that needs to be copied.
 * @return Promise
 *         The promise is resolved when copying completes or rejected if any
 *         (unexpected) errors occur.

   *        See: Debugger.Object.executeInGlobalWithBindings() for information

   *
   *        Use case: the variable view needs to update objects and it does so
   *        by knowing the ObjectActor it inspects and binding |_self| to the
   *        D.O of the OA. As such, variable view sends strings like these for

   *        - frameActor: a FrameActor ID. The FA holds a reference to
   *        a Debugger.Frame. This option allows you to evaluate the string in
   *        the frame of the given FA.
   *
   *        - url: the url to evaluate the script as. Defaults to
   *        "debugger eval code".
   *
   *        - selectedNodeActor: the NodeActor ID of the current
   *        selection in the Inspector, if such a selection
   *        exists. This is used by helper functions that can
   *        reference the currently selected node in the Inspector,

  This element contains the different toolbars in the console
    - primary, containing the clear messages button and the text search input.
      It can expand as much as it need.
    - filtered messages, containing the "X items hidden by filters" and the reset filters button.
      It should be on the same row than the primary bar if it fits there, or on its own 100% row if it is wrapped.
    - secondary, containing the filter buttons (Error, Warning, …).
      It should be on its own 100% row.

  Basically here's what we can have :

  -----------------------------------------------------------------------------------------------------------
  | Clear button - Open filter bar button - Filter Input | X items hidden by filters - Reset Filters button |
  -----------------------------------------------------------------------------------------------------------
  | Error - Warning - Log - Info - Debug - CSS - Network - XHR                                              |
  -----------------------------------------------------------------------------------------------------------

  or

  ------------------------------------------------------------------------------------
  | Clear button - Open filter bar button - Filter Input                             |
  ------------------------------------------------------------------------------------
  |                                X items hidden by filters  - Reset Filters button |
  ------------------------------------------------------------------------------------
  | Error - Warning - Log - Info - Debug - CSS - Network - XHR                       |

  Comment duplicated from browser-sets.inc:

  Search Command Key Logic works like this:

  Unix: Ctrl+J (0.8, 0.9 support)
        Ctrl+K (cross platform binding)
  Mac:  Cmd+K (cross platform binding)
        Cmd+Opt+F (platform convention)
  Win:  Ctrl+K (cross platform binding)
        Ctrl+E (IE compat)

  We support Ctrl+K on all platforms now and advertise it in the menu since it is
  our standard - it is a "safe" choice since it is near no harmful keys like "W" as
  "E" is. People mourning the loss of Ctrl+K for emacs compat can switch their GTK
  system setting to use emacs emulation, and we should respect it. Focus-Search-Box
  is a fundamental keybinding and we are maintaining a XP binding so that it is easy
  for people to switch to Linux.

     downloads and those of blocked downloads.

     A good rule of thumb is to try to determine the longest string possible
     that an in-progress download could display, and use that value in ch
     units.

     For example, in English, a long string would be:

     59m 59s left - 1022 of 1023 KB (120.5 KB/sec)

     Since Downloads Panel is redesigned to show the detail string including
     the hovering case for an item or an action button.
     Bug 1328519 is for discussing the detail rule of `downloadDetails.width`.
     -->
<!ENTITY downloadDetails.width            "50ch">

<!-- LOCALIZATION NOTE (downloadsSummary.minWidth2):
     Minimum width for the main description of the downloads summary,
     which is displayed at the bottom of the Downloads Panel if the
     number of downloads exceeds the limit that the panel can display.

     A good rule of thumb here is to look at the otherDownloads3 string
     in downloads.properties, and make a reasonable estimate of its
     maximum length. For English, this seems like a reasonable limit:

     999 files downloading

     that's 21 characters, so we set the minimum width to 21ch.
