| Summary | 0002870: Logbook: crashes when connecting to down MySQL server instance | ||||
| Description | The MySQL ODBC drivers cause the Logbook to crash if the Logbook is configured to use a MySQL database that's not available at the startup of the Logbook. The Logbook crashes, but the problem is that the Logbook's code (inside MFC, actually -- internal to the library) queries the MySQL ODBC driver for error information. When it does so, the drivers cause a crash instead of returning a useful error message. The callstack shows that the crash is when the Logbook tries to connect to the database (with the OpenEx() call). There's no way for the Logbook to know not to make that call -- it has to make that call, and expects an exception or a failure to be reported. | ||||
| Steps To Reproduce | 1) Start up the Logbook 2) Configure the Logbook to use a MySQL server instance 3) Set that MySQL Server instance as the Default database 4) Close the Logbook 5) Stop your MySQL server instance 6) Start the Logbook BUG#1) Crash at startup with the attached call stack | ||||
