11 # This file implements regression tests for SQLite library. The | |
12 # focus of this file is testing the operation of the library in | |
13 # "PRAGMA journal_mode=WAL" mode. | |
14 # | |
15 # More specifically, this file contains regression tests for the | |
16 # sqlite3_wal_hook() mechanism, including the sqlite3_wal_autocheckpoint() | |
17 # and "PRAGMA wal_autocheckpoint" convenience interfaces. | |
