-# This file implements regression tests for SQLite library.

-# This file implements tests to make sure SQLite does not crash or
-# segfault if it sees a corrupt database file.  It specifically focuses
-# on loops in the B-Tree structure. A loop is formed in a B-Tree structure
-# when there exists a page that is both an a descendent or ancestor of
-# itself.
-#
-# Also test that an SQLITE_CORRUPT error is returned if a B-Tree page
-# contains a (corrupt) reference to a page greater than the configured
-# maximum page number.
