- // Bug 1247100 - When a refresh is caused by an HTTP header,
- // onRefreshAttempted will be fired before onLocationChange.
- // When a refresh is caused by a <meta> tag in the document,
- // onRefreshAttempted will be fired after onLocationChange.
- //
- // 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 -
- // otherwise, null is set as the value of the mapping.
