# This file implements regression tests for SQLite library. The
|
||
|
|
# focus of this file is testing the operation of the library when
|
||
|
|
# recovering a database following a simulated system failure in
|
||
|
|
# "PRAGMA journal_mode=WAL" mode.
|
||
|
|
#
|
||
|
|
|
||
|
|
#
|
||
|
|
# These are 'warm-body' tests of database recovery used while developing
|
||
|
|
# the WAL code. They serve to prove that a few really simple cases work:
|
||
|
|
#
|
||
|
|
# walcrash-1.*: Recover a database.
|
||
|
|
# walcrash-2.*: Recover a database where the failed transaction spanned more
|
||
|
|
# than one page.
|
||
|
|
# walcrash-3.*: Recover multiple databases where the failed transaction
|
||
|
|
# was a multi-file transaction.
