# The following tests verify that hot-journal rollback works. As follows:
#
# 1. Create a large database.
# 2. Set the pager cache to be very small.
# 3. Open a transaction.
# 4. Run the following 100 times:
# a. Update a row.
# b. Copy all files on disk to a new db location, including the journal.
# c. Verify that the new db can be opened and that the content matches
# the database created in step 1 (proving the journal was rolled
# back).
