# This file implements regression tests for SQLite library. The
|

|
|
# focus of this file is testing the operation of the library in
|

|
|
# "PRAGMA journal_mode=WAL" mode.
|
||
|
|
#
|
||
|
|
# More specifically, this file contains regression tests for the
|
||
|
|
# sqlite3_wal_hook() mechanism, including the sqlite3_wal_autocheckpoint()
|
||
|
|
# and "PRAGMA wal_autocheckpoint" convenience interfaces.
