# Test this:
|
|
#
|
|
# 1. Page is DIRTY at the start of a transaction.
|
|
# 2. Page is written out as part of the transaction.
|
|
# 3. Page is then read back in.
|
|
# 4. Transaction is rolled back. Is the page now clean or dirty?
|
|
#
|
|
# This actually does work. Step 4 marks the page as clean. But it also
|
|
# writes to the database file itself. So marking it clean is correct -
|
|
# the page does match the contents of the db file.
