2016-11-30
| ||
| 16:54 | Add the remember(V,PTR) extension function which copies an SQL value into an application variable. (check-in: d2d30914d8 user: drh tags: trunk) | |
| 16:39 | Merge all the latest changes from trunk. (check-in: 7ca58a07d3 user: drh tags: est_count_pragma) | |
| 14:47 | Fix then handling of the (oversized) integer literal -0x8000000000000000. (check-in: 3816bb415e user: drh tags: trunk) | |
| 05:08 | Change the OP_DecrJumpZero opcode back to its old behavior of always decrementing, except top the decrementing when it reaches the largest negative number. (check-in: 9d0d8c2e7c user: drh tags: trunk) | |
| 04:07 | More improvements to boundary cases in the date/time functions, flowing out of branch coverage testing. (check-in: 1218005ab7 user: drh tags: trunk) | |
| 01:05 | Prevent a warning about integer overflow when using a very large negative LIMIT. (check-in: 96106d5620 user: drh tags: trunk) | |
| 00:48 | Further changes to the date/time functions to suppress harmless signed integer overflow warnings that could have occurred when doing out-of-range date calculations which, according to the docs, give undefined results. (check-in: dc453b3403 user: drh tags: trunk) | |
|
2016-11-29
| ||
| 20:39 | The documentation says that the built-in date-time functions give undefined results for dates before 0000-01-01 and after 9999-12-31. Change the actually implementation so that the answer given is really NULL. This also avoids unnecessary hand-wringing over an signed integer overflow that might otherwise occur when processing out-of-bound dates. (check-in: d410a83975 user: drh tags: trunk) | |
|
