| 21:07 | Avoid incrementing the SQLITE_LOOKASIDE_MISS_SIZE stat before sqlite3_open() returns. Fix test script problem in lookaside.test. (check-in: 3bd94e4317 user: drh tags: branch-3.25) | |

| 19:47 | Have each open database allocate its pTmpSpace when the first write cursor is opened, rather than on each insert or delete, for a small space savings and performance boost. (check-in: 99323552c0 user: drh tags: trunk) | |
| 18:31 | Small performance and size optimization for btreeUnlockIfUnused(). (check-in: 13c746f85d user: drh tags: trunk) | |

| 04:38 | Experiment using linear interpolation, instead of a strict binary search, when looking for integer-keyed rows on a single b-tree page. The experiment was not successful. The number of key comparisons is reduced by about 15%, but the added complexity of the search logic causes an overall reduction in performance. The patch is saved for historical reference only. (Closed-Leaf check-in: c705cf856d user: drh tags: linear-interpolation) | |
| 02:05 | Have the clearCell() routine return the cell size to the caller, rather than have the caller make a separate call to cellSizePtr(). (check-in: f21d217583 user: drh tags: trunk) | |

| 10:42 | Use sqlite3FkOldmask() in delete.c instead of assuming that foreign key constraints always require all columns of the deleted row to be stored in registers. (check-in: ce554a3934 user: dan tags: trunk) | |
| 09:05 | Remove unused parameter from sqlite3CodeRowTrigger(). Fix header comments for this function and CodeRowTriggerDirect(). (check-in: 0443f7c911 user: dan tags: trunk) | |
