11 # This file implements regression tests for SQLite library.
12 #
13 # This file implements tests to make sure SQLite does not crash or
14 # segfault if it sees a corrupt database file. It specifically focuses
15 # on loops in the B-Tree structure. A loop is formed in a B-Tree structure
16 # when there exists a page that is both an a descendent or ancestor of
17 # itself.
18 #
19 # Also test that an SQLITE_CORRUPT error is returned if a B-Tree page
20 # contains a (corrupt) reference to a page greater than the configured
21 # maximum page number.
