-/* |
-** This program tests the ability of SQLite database to recover from a crash. |
-** This program runs under Unix only, but the results are applicable to all |
-** systems. |
-** |
-** The main process first constructs a test database, then starts creating |
-** subprocesses that write to that database. Each subprocess is killed off, |
-** without a chance to clean up its database connection, after a random |
-** delay. This killing of the subprocesses simulates a crash or power |
-** failure. The next subprocess to open the database should rollback |
-** whatever operation was in process at the time of the simulated crash. |
-** |
-** If any problems are encountered, an error is reported and the test stops. |
-** If no problems are seen after a large number of tests, we assume that |
-** the rollback mechanism is working. |
