| 17:50 | If a call is made to sqlite3PagerAcquire when there are no outstanding references to any pages and the pager is in the error-state, try to exit the error-state at this point. Previously this was only attempted if the pager was configured to use exclusive mode. (CVS 6788) (check-in: 62db08bc user: danielk1977 tags: trunk) | |
