| 21:15 | For lsmtest, use a more portable means of setting open() files to binary. check-in: aea6e0ff user: mistachkin tags: trunk | |
| 20:35 | Adjust copy_file() lsmtest function so it works properly for locked database files on Win32. check-in: 54a38555 user: mistachkin tags: trunk | |
| 20:06 | Add the "PRAGMA secure_delete=FAST" option, which overwrites most deleted content without increasing the amount of I/O. Deleted content might persist on the free page list, however. And extra CPU cycles are used for zeroing, of course. check-in: 38978ce6 user: drh tags: trunk | |
