# This is designed to provoke a special case in the pager code:
#
# If an error (specifically, a FULL or IOERR error) occurs while writing a
# dirty page to the file-system in order to free up memory, the pager enters
# the "error state". An IO error causes SQLite to roll back the current
# transaction (exiting the error state). A FULL error, however, may only
# rollback the current statement.
#
# This block tests that nothing goes wrong if a FULL error occurs while
# writing a dirty page out to free memory from within a statement that has
# opened a statement transaction.
