# Test organization:
|
|
#
|
|
# 1.*: Test superlock on a rollback database. Test that once the db is
|
|
# superlocked, it is not possible for a second client to read from
|
|
# it.
|
|
#
|
|
# 2.*: Test superlock on a WAL database with zero frames in the WAL file.
|
|
# Test that once the db is superlocked, it is not possible to read,
|
|
# write or checkpoint the db.
|
|
#
|
|
# 3.*: As 2.*, for WAL databases with one or more frames in the WAL.
|
|
#
|
|
# 4.*: As 2.*, for WAL databases with one or more checkpointed frames
|
|
# in the WAL.
|
|
#
|
|
# 5.*: Test that a call to sqlite3demo_superlock() uses the busy handler
|
|
# correctly to wait for existing clients to clear on a WAL database.
|
|
# And returns SQLITE_BUSY if no busy handler is defined or the busy
|
|
# handler returns 0 before said clients relinquish their locks.
|
|
#
|
|
# 6.*: Test that if a superlocked WAL database is overwritten, existing
|
|
# clients run the recovery to build the new wal-index after the
|
|
# superlock is released.
