Organization of test case files:
lsmtest1.c: Data tests. Tests that perform many inserts and deletes on a
database file, then verify that the contents of the database can
lsmtest2.c: Crash tests. Tests that attempt to verify that the database
recovers correctly following an application or system crash.
lsmtest3.c: Rollback tests. Tests that focus on the explicit rollback of
transactions and sub-transactions.
lsmtest4.c: Multi-client tests.
lsmtest5.c: Multi-client tests with a different thread for each client.
lsmtest6.c: OOM injection tests.
lsmtest7.c: API tests.
lsmtest8.c: Writer crash tests. Tests in this file attempt to verify that
the system recovers and other clients proceed unaffected if
a process fails in the middle of a write transaction.
The difference from lsmtest2.c is that this file tests
live-recovery (recovery from a failure that occurs while other
clients are still running) whereas lsmtest2.c tests recovery
from a system or power failure.
lsmtest9.c: More data tests. These focus on testing that calling
lsm_work(nMerge=1) to compact the database does not corrupt it.
In other words, that databases containing block-redirects
can be read and written.
