ebf1ae1bdc mdbx: backport - mdb_drop optimization. 
If we know there are no sub-DBs and no overflow pages, skip leaf scan.

2016-03-30 19:46 GMT+03:00 Howard Chu <hyc@symas.com>:

That logic is backwards because I was preserving existing behavior,
i.e. make the page - including unused portions - look the same with
put() in the child txn as put() in the parent.  So with MDB_RESERVE
the entire page must be copied in case the user peeks at it before
writing to it.  Without MDB_RESERVE, the initial part of the page
body need not be copied since LMDB is about to overwrite it.

I'll comment that, unless that code should just go away.  Don't know
if this is the best behavior or it was just easier to code it than
to decide whether to cater to such obscure user behavior.  But
people do come up with special things do do about overflow pages.

aeea7ebb08 mdbx: backport - ITS#8321 a lot for cursor tracking. 
Multiple bugs were fixed in the cursor fixups which
adjust other open cursors in response to various write ops.

Includes:

 - ITS#8321 Fix del/dupsort.
   When deleting a dupsort key, if other cursors pointed at that key,
   set them to uninit'd, not EOF. They no longer have anything to
   point at.

 - ITS#8321 don't skip fixups on splitting cursors.
   Adjustments can't be skipped, in recursive calls each level must
   fixup their own level.

 - ITS#8321 fix mdb_cursor_chk().
   It was reporting spurious errors due to uninit'd cursors

 - ITS#8321 fix mdb_cursor_shadow().
   Set a valid txn so that cursor fixup code works on the shadows

 - ITS#8321 fix mdb_cursor_put.
   Ignore sub-cursors that shouldn't be fixed up

 - ITS#8321 track temporary cursors.
   In rebalance/split operations, temporary cursors need to be visible
   to propagate fixups

 - ITS#8321 simplify page_split fixups.

 - ITS#8321 reorganize page_split fixups.
   DUPFIXED fixups needed to occur after separator update.
   MDB_RESERVE handling moved after split fixup.
