checkpoint_1:
create two dbs, db_test (observed) and db_control (expected)
loop n times:
modify both dbs
checkpoint db_test
modify db_test only
copy db_test file (system(cp)) to db_temp
compare db_temp with db_control
continue test using db_temp as db_test instead of db_test
delete old db_test
checkpoint_2,3 were subsumed into 1.
TODO: Add callback to toku_checkpoint(), called after ydb lock is released.
(Note, checkpoint_safe_lock is still held.)
checkpoint_4:
Callback can do some inserts, guaranteeing that we are testing that inserts
are done "during" a checkpoint.
checkpoint_5:
Callback does unrelated open, close, and related close.
checkpoint_6:
Callback triggers a thread that will perform same operations as:
* checkpoint_4
* checkpoint_5
* delete (relevant db)
* delete (irrelevant db)
* take checkpoint safe lock using YDB api, do something like insert and release it
but those operations happen during execution of toku_cachetable_end_checkpoint().
checkpoint_7
take atomic operation lock
perform some inserts
on another thread, call toku_checkpoint()
sleep a few seconds
perform more inserts
release atomic operations lock
wait for checkpoint thread to complete
verify that checkpointed db has all data inserted
