| 13:35 | Remove the ill-designed "-end" option from the command-line shell. Instead, allow multiple SQL or dot-commands as command-line arguments. Any -cmd commands are processed first, followed by other command-line arguments, for backwards compatibility. check-in: 24fa2e98 user: drh tags: trunk | |
| 11:54 | Add the -end option to the command-line shell, which forces it to exit after reading prior command-line options (presumably including one or more -cmd options) and without reading standard input. check-in: b59397b1 user: drh tags: trunk | |

|
2014-11-18
| ||

| 20:16 | Update a couple of test cases to account for the fact that ROLLBACK does not always abort all running SELECT statements. check-in: abccda76 user: drh tags: trunk | |
