# TEST test112

# TEST Test database compaction with a deep tree.

# TEST

# TEST This is a lot like test111, but with a large number of
|
||||
# TEST entries and a small page size to make the tree deep.
|

# TEST To make it simple we use numerical keys all the time.
|
||||
# TEST
|
||||
# TEST Dump and save contents. Compact the database, dump again,
|
||||
# TEST and make sure we still have the same contents.
|
||||
# TEST Add back some entries, delete more entries (this time by
|
||||
# TEST cursor), dump, compact, and do the before/after check again.
