KProgressDialog will be displayed. Its progress bar will be updated whenever another
|
|
table's data compacting is performed. User can click "Cancel" button in any time
|
|
(except the final committing) to cancel the operation. In this case,
|
|
it's guaranteed that the original file remains unchanged.
|
|
|
|
This is possible because we rely on SQLite's VACUUM SQL command, which itself temporarily
|
|
creates a copy of the original database file, and replaces the orginal with the new only
|
|
on success.
