21 check-ins using file src/vdbe.c version 51e754ee

2016-10-03
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)
2016-10-01
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)
2016-09-30
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)
