Changes In Branch tkt-a8a0d2996a Excluding Merge-Ins
This is equivalent to a diff from db7d62c8 to 0b95b7a8
|
2014-03-24
| ||
| 15:00 | Fix arithmetic operators so that they do not change the affinity of their input operands. Ticket [a8a0d2996a]. (check-in: 221f8f94 user: drh tags: trunk) | |
| 12:33 | Cancel column-cache entries that are involved in a comparison operator since the comparison might have forced an affinity change. Originally proposed as a fix for ticket [a8a0d2996a], but later determined to be incorrect. (Closed-Leaf check-in: 0b95b7a8 user: drh tags: tkt-a8a0d2996a) | |
| 11:23 | Avoid attempting to mmap memory from an offset that is not a multiple of the system page size on systems with page sizes larger than 32KB. (check-in: db7d62c8 user: dan tags: trunk) | |
|
2014-03-23
| ||
| 16:29 | Avoid a possible use of an uninitialized variable following an I/O or OOM error. (check-in: 641408a1 user: drh tags: trunk) | |
|
2014-03-20
| ||
| 09:42 | Add a test to ensure os_unix.c works with 64KiB OS pages. (Closed-Leaf check-in: e3d2be3b user: dan tags: shm-mapping-fix) | |
Changes to src/expr.c.
