* This program performs unit tests for the update log functions in kdb_log.c.
* Right now it contains only a test for issue #7839, checking that
* ulog_add_update behaves appropriately when the last serial number is
* reached.
*
* The test program accepts one argument, which it unlinks and then maps with
* ulog_map(). This lets us test all of the update log functions except for
* ulog_replay(), which needs to open and modify a Kerberos database.
* ulog_replay is adequately exercised by the functional tests in t_iprop.py.
