19:38 | Fix problems in estimating the number of rows visited by a range query using sqlite_stat4 data when the column subject to the range query is not the leftmost of the index. (check-in: 9228aaf5 user: dan tags: sqlite_stat4) | |
16:17 | Use a binary search instead of a linear scan when comparing a sample key against data from the sqlite_stat4 table. (check-in: e50dc305 user: dan tags: sqlite_stat4) | |
12:21 | Fix a segfault in "ALTER TABLE t1 ADD COLUMN b DEFAULT (-+1)". Also an assert() failure that could occur if SQLITE_ENABLE_STAT4 were not defined. (check-in: 9fec3e38 user: dan tags: sqlite_stat4) | |

15:57 | Remove the unused sqlite3Utf8to16() utility function. (check-in: 9159b43e user: drh tags: sqlite_stat4) | |
15:52 | When estimating the number of rows scanned using data from the sqlite_stat4 table, avoid allocating UnpackedRecord and KeyInfo structures until they are definitely required. (check-in: 353950a5 user: dan tags: sqlite_stat4) | |
