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. |
