        <rdar://problem/5415006> Command Left in a To Do causes caret to disappear

        The selection was ending up inside non-editable content at the To Do Options
        arrow image, rather then at the editable position just to the left of that image.
        The problem was that startPositionForLine looked only at line boxes, and there
        is no linebox for the editable position at the far left of a To Do, which is
        a table. Addressed by having startPositionForLine use table offset 0 instead

        REGRESSION: Undoing a deletion that is part of an open typing command fails to reinsert the caret
        
        We recently made Undo of a series of deletes select all of the 
        characters that were deleted, not just the most recently deleted
        character.  But the code that did this set a new starting selection 
        after every delete, even those that were part of an open typing 
        command that started with character insertions or forward deletes, 
        operations that when undone, remove the starting selection being 
        set from the document.
        
        After this change we only set a new starting selection if the open typing
        command was opened by a backward delete. The new behavior matches TextEdit.  
        We don't do something similar or forward deletes because TextEdit opens 
        and closes a new typing command on forward delete (added a FIXME about this).

        Tweaked the cache eviction model to better balance between live and 
        dead resources.
        
        For the sake of avoiding evictions during the PLT, the old model 
        required the sum of dead and live resources to grow to twice the cache 
        capacity before evicting, and would then evict dead or live down to 0 
        if necessary. This was a too-high high water mark, which would nullify 
        much of the value of eviction, and a too-low low water mark, which 
        would nullify much of the value of the LRU-SP strategy.
        
        This patch changes the model in 3 ways.
        
        1. The new model for dead resources is a flexible window with a fixed 
        minimum and maximum. The dead resource window is big when live resource 
        pressure is small, and vice versa. This has the immediate advantage of
        cutting the high water mark by up to 50%. It also enables the following
        tunable optimizations in future patches:
            a. A dead resource limit of 0 for clients who want that. (Just set
            the fixed maximum to 0.)
            b. A much higher low water mark. (Just set the fixed minimum to, 
            say, 25% of the cache's capacity.)
            c. A much lower high water mark for users who browse simple pages
            in one tab. (Just set the fixed maximum to, say, 50% of the cache's
            capacity.)
        
        I plan to make the changes that actually take advantage of these 
        tunable optimizations in another check-in.

        The new model won't hurt the PLT because it will notice the PLT's low
        live resource size, and up the dead resource capacity in response. For
        the same reason, the new model should establish a good balance in 
        real-world use.
        
        2. Live resource eviction is now based on size(), not encodedSize().
        So, a page with lots of large, encoded images will start evicting 
        resources, if necessary, even before all the images paint. This allows 
        you to more accurately stipulate an exact high water mark.
        
        3. When pruning, prune to a small percentage below capacity, to avoid
        just having to prune again immediately.

        Layout tests pass. PLT shows no regression.

        * history/PageCache.cpp:
        (WebCore::PageCache::releaseAutoreleasedPagesNow): Updated for rename.

        - fix <rdar://problem/5415029> In Mail, a crash occurs at WebCore::Node::isDescendantOf()
          when attempting to delete a selection in a table

        The bug was caused by createMarkup trying to operate on a range that
        has an endpoint in the delete button DOM, because it removes that DOM
        during its operation! Still working on a regression test -- it's hard
        to make the kind of bad selection that's needed with the DOM, so I might
        have to use the eventSender.

        * editing/DeleteButtonController.h: Made some of the identifiers private.
        We can make them public if we need to use them. Added a getter function
        for the container element so we can figure out if a given node is inside
        the DOM added for the delete button.

        * editing/markup.cpp:
        (WebCore::moveEndpointsBeforeNode): Added. General purpose helper function
        that moves endpoints of a range to before a given node -- we do this before
        removing the delete button, so the endpoint is where the delete button was,
        rather than having an endpoint that's not in the document.
        (WebCore::createMarkup): Always return empty string, not null string.
        Get the document by calling ownerDocument on the range rather than getting
        the document of the commonAncestorContainer. That's because we need to
        get at the delete button before calling commonAncestorContainer. Call
        moveEndpointsBeforeNode to move the range endpoints out of the delete
        button interface before calling disable() which will remove it from the
        DOM if it's in there. Added an early return for the case where commonAncestor
        is non-0. If this happens, we would crash later because pastEndNode would
        not be in the tree. This change alone would prevent the crash, but we'd get
        bad markup, so we need the moveEndpointsBeforeNode fix. Added null checks
        for the frame to the range version as in the single-node version so this
        won't crash immediately on documents that are not in a frame. For the
        single-node version, added a check if a ndoe of 0 and a node inside the
        delete button user interface, and return the empty string for those cases.

        <rdar://problem/5394708> - Crash on launch with corrupt icon database

        The main part of the fix is to not disable SQLite's default level of protection - to leave the sync options at their normal,
        mostly safe levels.  

        But in case lightning strikes at the exact right moment and someone ends up with a corrupt database, add some support code to
        detect that condition and recover from it.  

        This is mainly accomplished by exposing the "PRAGMA integrity_check;" facilities of sqlite through IconDatabase SPI as well as
        running that integrity check if a journal file is detected at launch (a strong indication that the last quit was not clean).
        There's also a method exposed to allow clients to tell the icon database "I suspect something bad happened, please check integrity"

        * loader/icon/IconDatabase.cpp:
        (WebCore::IconDatabase::checkIntegrityBeforeOpening): Allow clients to suggest an integrity check
        (WebCore::IconDatabase::open): Add a check to see if the journal file for the database exists.  If it does, run the integrity
          check.  Also run the check if a client has suggested it to be necessary.
          If the integrity-check fails, we sadly have to destroy the database and recreate from scratch.
          Also - quite importantly - do not adjust the default sync preferences for the SQLDatabase.  They were an optimization that 
          might have been valid at one time but no longer affects any benchmarks we care about.

        Fix for <rdar://problem/5404899> REGRESSION: Mail crash in 
        WebCore::FontFallbackList::fontDataAt() after dragging image into 
        text multiple times

        We were crashing because style information was not up-to-date. This 
        patch fixes the problem in two ways:

        Style information was not up to date at the time of the crash 
        because the document thought there was still a pending style sheet. 
        The pending style sheet counter was incremented when a call to 
        cloneNode from Mail cloned a style node with an imported style 
        sheet. Because Mail disables the cache, the style sheet did not 
        load immediately for the cloned node, and we do not check again to 
        see if it has loaded in time to decrement the pending style sheet 
        counter before the crash point. The fix here is only to increment 
        the pending style sheet counter for elements that are already in 
        the document.
        * dom/StyleElement.cpp:
        (WebCore::StyleElement::insertedIntoDocument): If we have a CSS 
        style sheet that is currently loading, increment the pending style 
        sheet counter. This should keep the counter accurate in the case 
        where a style node is cloned and then immediately inserted into the 
        document.
        (WebCore::StyleElement::removedFromDocument): If we have a CSS 
        style sheet that is currently loading, decrement the pending style 
        sheet count. This is required to keep the correct balance, given 
        the change above.
        (WebCore::StyleElement::createSheet): Only addPendingSheet() and 
        checkLoaded() if we are in the document.

        Here is Darin's original fix. It seems worth keeping this fix too. 
        Font style information should not cause a crash if there are still 
        pending style sheets. This is good belt-and-suspenders in case 
        there is another way to run into this bug with a wacky timing 
        issue.

        better decisions about what data to evict when the cache is small. For

        Refactored live decoded resource eviction to be more modular /

        This fixes one known place where we forgot to hook into the live 
        decoded eviction mechanism -- canvas. There might be other, unknown 
        places. In a canvas test page, which I broke off from the Safari 
        pageout test, I saw an RPRVT reduction of ~10MB.
        
        A few renames:
        - "m_lastLiveAccessTime" => "m_lastDecodedAccessTime" because the data
        point we're recording is access to the resource in decoded form.
        
        - "liveResourceAccessed" => "didAccessDecodedData" for the same reason.

        - "pruneAllResources" => "pruneDeadResources" because this function 
        does not prune live resources.
        
        And the fix:
        Instead of updating cache metadata at the call site whenver drawing an 
        image, just have an image notify its observer whenever it draws. The 
        observer, which is a CachedResource, can then update the metadata.

        Use the ScrollView/Widget design of the Windows port to only use one
        native window for the whole page. This will make it possible to implement
        FrameLoaderClientGdk::createFrame.

        In contrast to the windows port the ScrollBars are GtkWidgets. To paint them
        at the right position we need to position them correctly. To not scroll the
        ScrollBar's belonging to the ScrollView a ScrollViewScrollbar is introduced with
        a different geometryChanged method.

        To allow the Gtk+ way of scrolling the ScrollView allows to get GtkAdjustments
        set. In this case no ScrollViewScrollbar will be created.

        - fix <rdar://problem/4889753> REGRESSION: Selection doesn't continue with drag selecting
          when autoscrolling vertically (in Notes as well as Safari)

        The bug doesn't happen inside DumpRenderTree, so I was unable to make an automated
        regression test.

        * manual-tests/autoscroll-when-outside-window.html: Added.

        check for the layer's renderer and the document, neither of which can be null. Call
        the new updateSelectionForMouseDrag instead of doing selection updating here.

        * page/EventHandler.h:
        * page/EventHandler.cpp:
        (WebCore::EventHandler::handleMouseDraggedEvent): Refactored most of the logic
        about updating the selection into updateSelectionForMouseDrag.
        (WebCore::EventHandler::updateSelectionForMouseDrag): Added. The public version of
        this function takes no parameters, and is for use from auto-scrolling code. The
        private version of this function takes node and point parameters and contains the
        shared code, including everything from updateSelectionForMouseDragOverPosition.
        Aside from the code motion, variable name changes, and sharing more code, this
        differs from the old code in RenderLayer::autoscroll in the following ways:

          1) The old code did hit testing only in the layer that was auto-scrolling,
             and the new code instead starts the hit testing at the root layer, which is
             better because it's the same thing we do for mouse moved events. Further,
             the code to do this by calling convertToLayerCoords had a bug  because the
             x and y variables were uninitialized.
          2) The old code passed false for active to HitTestRequest, which was wrong.
             The new code passes true. This flag needs to be true for hit testing done
             while the mouse is down and false for hit testing done while the mouse is up.
          3) The old code did not have the SVG-specific logic to match the mouse moved case.
          4) The old code wouldn't do any selection updating if the return value from hitTest
             was false, which is incorrect. The new code ignores the return value as it should.

        Added a thrash check to live decoded resource eviction.
        
        Here's the strategy: Stamp every image with its paint time. Don't evict 
        a live decoded resource until another resource paints with a reasonably
        (1 second) larger time stamp. 
        
        If no other resource paints, or another resource paints, but very soon 
        after the resource in question, the resource in question is very likely 
        to paint again soon. In fact, it's probably still on screen. So we 
        leave it alone. (Previously, we evicted it on a timer, but that would 
        evict a resource that was still on screen, hurting speed without 
        helping memory use.)

        In theory, this algorithm allows a single large resource or closely 
        related set of resources to linger in the live decoded cache even 
        though the cache is over its limit. However, that can only happen as 
        long as no other resource ever paints again, which guarantees an 
        absolute cap on cache memory usage from then on. Also, the resources 
        will only linger as long as they remain live. Upon going dead, they 
        will flush. Also, these circumstances are so rare that they are almost 
        impossible to encounter in the wild. So don't sweat it.
        
        Stop evicting if the next resource painted too recently:

        Fix for <rdar://problem/5354689>

        - Use document variable to determine permissions instead
          of traversing the frame tree.

        Make sure to clear out the parent of the ellipsis box so that it doesn't
        trigger the consistency check for line boxes.

        Back out fix for <rdar://problem/5366582> and replace it with the correct
        fix.  Make sure to delete the line box tree before splitting an inline flow
        into a continuation.  The added layout test for the original checkin covers
        the problem.
