# 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.
|
|
#
|
|
# Specifically, it tests the case where a connection opens an empty
|
|
# file. Then, another connection opens the same file and initializes
|
|
# the connection as a WAL database. Following this, the first connection
|
|
# executes a "PRAGMA page_size = XXX" command to set its expected page
|
|
# size, and then queries the database.
|
|
#
|
|
# This is an unusual case, as normally SQLite is able to glean the page
|
|
# size from the database file as soon as it is opened (even before the
|
|
# first read transaction is executed), and the "PRAGMA page_size = XXX"
|
|
# is a no-op.
|
