# This file implements regression tests for the SQLite library, focusing
# on the incremental vacuum feature.
#
# The tests in this file were added at the same time as optimizations 
# were made to:
#
#   * Truncate the database after a rollback mode commit, and
#
#   * Avoid moving pages to locations from which they may need to be moved
#     a second time if an incremental-vacuum proccess is allowed to vacuum
#     the entire database.
