# Simple test:
|
||||
#
|
||||
# Test cases *.1 - *.6:
|
||||
#
|
||||
# + Create a database of blobs roughly 50 pages in size.
|
||||
#
|
||||
# + Set the db cache size to something much smaller than this (5 pages)
|
||||
#
|
||||
# + Within a transaction, loop through the set of blobs 5 times. Update
|
||||
# each blob as it is visited.
|
||||
#
|
||||
# + Test that the wal file is roughly 50 pages in size - even though many
|
||||
# database pages have been written to it multiple times.
|
||||
#
|
||||
# + Take a copy of the database and wal file. Test that recovery can
|
||||
# be run on it.
|
||||
#
|
||||
# Test cases *.7 - *.9:
|
||||
#
|
||||
# + Same thing, but before committing the statement transaction open
|
||||
# a SAVEPOINT, update the blobs another 5 times, then roll it back.
|
||||
#
|
||||
# + Check that if recovery is run on the resulting wal file, the rolled
|
||||
# back changes from within the SAVEPOINT are not present in the db.
|
||||
#
|
||||
# The above is run twice - once where the wal file is empty at the start of
|
||||
# step 3 (tn==1) and once where it already contains a transaction (tn==2).
