18:13 | Allow deterministic functions in the WHERE clause of a partial index. (check-in: c6e9b942 user: drh tags: trunk) | |
16:33 | Size and performance optimizations on the sqlite3ExprAssignVarNumber() routine. (check-in: 109852e5 user: drh tags: trunk) | |
15:28 | Avoid unnecessary strlen() calls in sqlite3ExprAssignVarNumber() by passing in the token length from the parser. (check-in: d15ae2e5 user: drh tags: trunk) | |
14:44 | Avoid unnecessary memset() calls in the query optimizer. (check-in: 5bb7cde0 user: drh tags: trunk) | |
12:56 | Fix an obsolete comment on a variable definition in expr.c. No code changes. (check-in: 012ff6dd user: drh tags: trunk) | |
02:59 | Make sure the sqlite_sequence table is updated when an optional xfer optimization is used. Fix for ticket [7b3328086a5c1]. (check-in: 81e4d4f8 user: drh tags: trunk) | |
01:21 | Allocate Parse objects off of the stack where appropriate for a substantial performance increase and a size reduction. (check-in: ea8affa9 user: drh tags: trunk) | |

| ||
23:55 | Add SQLITE_USE_ALLOCA to the --lean configuration in speed-check.sh. (check-in: fe07609e user: drh tags: trunk) | |
21:43 | Rearrange fields in the Parse object to reduce the amount of initialization required. (check-in: 361940b4 user: drh tags: trunk) | |
20:43 | Reduce the width of a memset() to avoid double-initializing some variables. (check-in: 34edbfd1 user: drh tags: trunk) | |
19:32 | Remove an unnecessary memset() call. (check-in: a76bff74 user: drh tags: trunk) | |
19:21 | Use sqlite3DbMallocRawNN() where appropriate, instead of sqlite3DbMallocRaw(). (check-in: 54a449a4 user: drh tags: trunk) | |
16:53 | Make sure deleting an unused prepared statement does not reference uninitialized fields in the structure. (check-in: 7983eef0 user: drh tags: trunk) | |
11:39 | Avoid accessing Vdbe.pc if it is uninitialized. Check Vdbe.magic first. (check-in: 6ac6e446 user: drh tags: trunk) | |
00:37 | Avoid unnecessary zeroing of fields in the Vdbe object when it is allocated. (check-in: 1e21bbe8 user: drh tags: trunk) | |

22:24 | Avoid initializing the column-cache section of the Parse object, since entries in the cache will be initialized as they are used, and avoiding the initial memset() saves many CPU cycles. (check-in: 63cf7eaf user: drh tags: trunk) | |
21:20 | Fix an always-true conditional left over from the previous commit. (check-in: ab12fce3 user: drh tags: trunk) | |
20:22 | Fix the Parse.aColCache column cache so that all of the valid entries are in the first Parse.nColCache slots. (check-in: 60285020 user: drh tags: trunk) | |
19:14 | Another simplification to the Parse object. (check-in: c1419727 user: drh tags: trunk) | |
18:35 | Remove unnecessary fields from the Parse object. (check-in: 814e41da user: drh tags: trunk) | |
17:46 | Avoid unnecessary Mem initializations when generating a new sqlite3_stmt object. (check-in: 47ae1cda user: drh tags: trunk) | |
