12:08 | Two if statements should be asserts. GCC was silently ignoring them, hence the problem did not show up in coverage testing. Ticket #3333. (CVS 5607) (check-in: 635933b1ca user: drh tags: trunk) | |

07:12 | If the sector size is greater than the database page size, SQLite journals all pages that lie within a sector before writing to any of them. This change ensure that a journal sync does not occur halfway through journalling the set of pages that belong to a single sector. (CVS 5605) (check-in: 16f612d61e user: danielk1977 tags: trunk) | |
