Firefox/Projects/Asynchronous Add Visit

Implement a way to add visits to Places with. This will replace what nsIGloablHistory2::addURI and nsIGlobalHistory3::addDocumentRedirect does now.

Current API design looks something like this (added to IHistory):

enum VisitFlags {
  /**
   * Whether the URI was loaded in a top-level window.
   */
  TOP_LEVEL = 0 << 1,
  /**
   * Whether the URI was loaded as part of a permanent redirect.
   */
  REDIRECT_PERMANENT = 0 << 2,
  /**
   * Whether the URI was loaded as part of a temporary redirect.
   */
  REDIRECT_TEMPORARY = 0 << 3,
};

/**
 * @param aURI
 *        The URI of the page being visited.
 * @param aReferrer
 *        The URI of the referring page.
 * @param aFlags
 *        The VisitFlags describing this visit.
 * @param aRedirectedFrom [optional]
 *        The URI this URI was redirected from, or NULL if not a re-direct.
 */
NS_IMETHOD VisitURI(
  nsIURI* aURI,
  nsIURI* aReferrer,
  PRUint32 aFlags,
  nsIURI* aRedirectedFrom = NULL
) = 0;

Status

• IN FLIGHT. See bug 556400 for more details for now!
• Problem is a bit big and frecency updates has been split off into bug 556631

Goals

• Remove synchronous I/O off of the main thread
• Collect all the data we need in one call from docshell

Non-Goals

• Replace nsINavHistoryService::AddVisit with this new API

Requirements

• No synchronous I/O is to be done with the new API
• Implement this on IHistory
• IHistory should dispatch NS_LINK_VISITED_EVENT_TOPIC instead of docshell
• VisitURI should add the referrer if we do not have it in the database
