+
+    Split sweep into two passes: one that walks the handle list without locking and finds candidate handles to close, and a second pass holding the handle list lock that removes dead handles.

+
+    Add statistics to track internal/overflow/leaf pages in cache.
+    
+    It is often useful to know if a cache is full of internal pages. I could have added page count tracking, but byte count tracking seems more useful (enough to justify the extra performance overhead).

+
+    Update the eviction server to not set stuck if it isn't full.
+    
+    When only looking for pages to force out, the cache isn't really stuck.  The trouble is that if we set stuck the eviction server doesn't clear walks which can lead to it always holding a reference t othe page we (really) want to evict.

+    Add a test case for checkpoint consistency.
+    
+    We recently fixed a bug where updating a page after the write leaves phase of a checkpoint had completed, then either checkpointed again or closed the database. We would end up with inconsistent data. That was the case because we weren't marking trees dirty all the time.

+    This test case reproduces the scenario so we don't reintroduce the failure.

+
+    This does not mean WT_SESSION.truncate can't return WT_NOTFOUND in some cases, the first thing cursor truncate does is a cursor remove call in order to acquire the page's write generation information -- that remove call does the usual "discard my current reference and get a new one" work, which allows another deleting thread to race and remove one of the truncate's start/stop keys.

+
+    When doing truncates, if we see a clean page in memory, try to evict it before truncating.  It should be cheap (just freeing memory), and if the eviction succeeds, the fast truncate code can kick in and mark the whole page deleted immediately.  Otherwise, truncate will mark each record on the page deleted, and the next time through will try to force that page out, which has to go through reconciliation to figure out that all of the records are deleted.

+
+    There's a problem that went in in #1282, the key difference is that we are setting a split boundary at the end of the first page when there is more than a page worth of data. See also #1630 and #1631. This is an alternate approach to #1631: the real change is to fallthrough into the split case if the next item won't fit, callers of the split code can't handle failure from split, it has to create enough room for the next item to be entered into the buffer.

+    Fixes for split cache accounting: multi-page splits weren't correctly accounting for the allocated WT_REFs, insert splits weren't correctly handling the new right-page's instantiated key (the parent needs to be incremened by both the left- and right-hand page's keys, and cannot assume it's the same size as the original WT_REF's key), insert splits need to increment the parent page's WT_REF size by two, not one.

+
+    Start with clean trees so we can detect updates racing with sweep.
+
+    Use a deleted ref to a leaf page that is created on first update, which is the same state the tree should be in if an empty leaf page is evicted.  The only wrinkle is that bulk operations expect to find a leaf page in the tree: create it explicitly before the bulk insert starts.  This was probably a bug before: if we had created a tree and kept it around for long enough with cache pressure before a bulk load started, the initial leaf page could have been evicted.

+
+    We no longer calculate allocation overhead per allocation chunk, revert the workaround the problem with page memory size calculations during splits where we forced the new parent page memory size to 5% of its current value; reference #1564, #1565. This fixes a problem where 5% of a page's memory footprint isn't large enough to accommodate the cache decrements that will be done in the page's future, leading to page underflow.
+
+    Minor cleanups: we no longer calculate allocation overhead per allocation chunk, the macro WT_MEMSIZE_ADD is no longer needed at all, and WT_MEMSIZE_TRANSFER is renamed to WT_MEM_TRANSFER.

+
+    I believe we can race with pages being marked clean or dirty, which means we need to entirely divorce the page's dirty-byte count from page state: the page's dirty-byte count is just a value that tells us how many dirty bytes this page has contributed to the cache's total dirty-bytes count.  Sync the cache's information to that value when possible, but don't worry if we can't.

+
+    The size of the file is decreasing each time, so compacting 10 times, at 10%, is not sufficient to drive a file to its smallest size. The right fix is probably to get better information from the block manager as to exactly how much the size of the file has decreased, but that's messy, especially when you consider the checkpoints requires to get to that smallest size. For now, do 100 compaction attempts instead of 10, and depend on the no-progress state and/or the compaction timeout to limit the amount of time we spend here.

+
+    Changes in #1204, #1288 mistakenly changed the values for some error defines, which breaks backward compatibility. (The WT_DEADLOCK error name sorted differently from WT_ROLLBACK, and we were assigning error values based on the sort order in a script.) Revert the change, and make sure it doesn't happen again.
