15:16
Changes to help ensure that a multiplication does not overflow when computing the number of bytes needed for a memory allocation, and cause a malfunction. No problems existing problems were discovered. However, these changes should help to ensure that no problems arise in the future. check-in: 17349a49 user: drh tags: safer-malloc

Ensure that the sqlite3StrAccumAppend() routine is never called with a NULL second argument. Doing so is harmless when N==0, but it causes an assert() to fail that was placed to quiet static analyzers. Closed-Leaf check-in: f03fbf37 user: drh tags: tkt-55746f9e

09:35
Modify internal function whereLoopAdjustCost() so that it does not prefer a skip-scan over a regular index scan even if the regular scan uses a subset of the WHERE terms used by the skip-scan. check-in: 88a5758d user: dan tags: experimental-costs
08:49
Fix an error in estimating of the number of rows visited by a range scan. check-in: d491de62 user: dan tags: experimental-costs
