|
2020-05-26
| ||
| 11:10 | Changes to sqlite3SelectNew() to work around a false-positive warning from GCC-10. The code is very slightly larger and slower as a result. (check-in: 04e1edd8 user: drh tags: trunk) | |
|
2020-05-25
| ||
| 12:02 | Make sure variable declarations are at start of scope even when SQLITE_ENABLE_SNAPSHOT is used. (check-in: a77ceaf6 user: drh tags: trunk) | |
| 01:31 | Attempt to work around a false-positive warning in the CGo compiler. (Closed-Leaf check-in: d4bf60f4 user: drh tags: cgo-warning-workaround) | |
|
2020-05-24
| ||
| 12:36 | Version number to 3.32.1. (check-in: 56e5063c user: drh tags: trunk) | |
| 03:38 | When rewriting a query for window functions, if the rewrite changes the depth of TK_AGG_FUNCTION nodes, be sure to adjust the Expr.op2 field appropriately. Fix for ticket [7a5279a25c57adf1] (check-in: ad7bb70a user: drh tags: trunk) | |
Changes to src/select.c.
