    Reland "Extend bookmark sync code with support for favicon deletion" · 55b3fe20
    Mikel Astiz authored
    This is a reland of d63652c8
    
    The new version reverts a change in tests (removal of
    urls_with_favicons_) which presumably introduces flakiness on Mac.
    My hypothesis is that using urls_with_favicons_ hides a race
    condition that predates my patch, because the failing test is
    unrelated to favicons, TwoClientBookmarksSyncTest.Sanity, and the
    failing logs surface title mismatches as well:
    [...:bookmarks_helper.cc(377)] Title mismatch: Yahoo vs. Google
    
    Original change's description:
    > Extend bookmark sync code with support for favicon deletion
    > 
    > Recent patches have introduced new favicon scenarios by handling cases
    > where a site's content changes to not contain favicons.
    > 
    > Updating sync code to handle these events is needed to prevent sync
    > from resurrecting the favicon, due to not knowing about the deletion
    > and hence sync-ing it back to the local cache.
    > 
    > One notable change is that the new logic will introduce the concept of
    > sync-ed bookmark protos having neither an icon URL (field |icon_url|)
    > nor favicon image data (field |favicon|). Ancient versions of chrome
    > (prior to M25) didn't sync these fields and would be incompatible
    > (although not really badly) but too old for us to care.
    > 
    > Manually tested sync-ing across two patched instances of Chrome desktop
    > (Linux):
    > - Propagate deletions of bookmark favicons (after page content changes).
    > - Restoring deleted bookmark favicons (after page content changes).
