|
2018-12-23
| ||
| 21:27 | Split the code generation for the RHS of IN operators and for SELECT and EXISTS expressions into two separate subroutines, because there is now little commonality between those to functions.

| 20:30 | Remove the column-cache from the code generator. The column-cache has been a persistent source of bugs for years and with recent improvements in the performance of OP_Column, it no longer provides a benefit. After the column cache is removed, the binary is almost 2KB smaller and the speed-check.sh performance test is over 3 million cycles faster. (check-in: cdff3af7be user: drh tags: trunk) | |

| 15:16 | Ensure that all expressions that are to be evaluated once at the start of a prepared statement (the Parse.pConstExpr expressions) pass the sqlite3ExprIsConstantNotJoin() test. It is not sufficient to pass just the sqlite3ExprIsConstant() test as that would allow through column references that are bound to constants by the WHERE clause in the constant propagation optimization. This fixes a problem discovered by OSSFuzz. (check-in: 8bc7f84c39 user: drh tags: trunk) | |

| 23:04 | Completely remove the column cache logic, which has been a persistent source of bugs for many years. Due to recent enhancements to the performance of the OP_Column opcode, removing the column cache actually makes speed-check.sh run faster. Removing the column cache also saves about 1,800 bytes of code space. (check-in: 3f5f60cd75 user: drh tags: omit-column-cache) | |
| 20:19 | Fix the handling of sub-queries with LIMIT clauses by the optimization activated by compile-time symbol SQLITE_COUNTOFVIEW_OPTIMIZATION. (check-in: 21235d9a41 user: dan tags: trunk) | |
| 15:58 | Fix the OP_SeekRowid opcode so that it has no type-change side-effects on the key register in P3. This fixes an obcure problem that arises when doing equi-joins between a table with a TEXT column against another table with an INTEGER PRIMARY KEY. The original problem was discovered when OSSFuzz created such a query and hit an assert() in OP_VerifyTabCol that was specifically designed to catch these kinds of errors at run-time. Test cases for this fix are in TH3. (check-in: fa94b49e02 user: drh tags: trunk) | |

| 16:24 | Do not allow a column reference that is converted into a constant by the WHERE-clause constant propagation optimization to be moved to the init-time constant expression list, as the table reference will not work there. This fixes a problem found by OSSFuzz. (check-in: d30b2a9473 user: drh tags: trunk) | |

| 18:19 | Performance improvement to sqlite3ExprCollSeq(). With this change, the performance of speed-check.sh is within 400,000 cycles of trunk. (check-in: a5f86f49b7 user: drh tags: propagate-const-opt) | |
| 18:12 | Faster implementation of sqlite3IsBinary(). (check-in: be05d0db09 user: drh tags: propagate-const-opt) | |

| 16:57 | Constant propagation is now restricted to just the WHERE clause. The mechanism is changed to take affinity and collation into account. This seems to give correct answers. But the search for constant propagation costs 4 million cycles in the speed test. (check-in: 82c67efb72 user: drh tags: propagate-const-opt) | |

This then demonstrates that the current implementation is inadequate since it does not take into account collating sequences. (check-in: 57eb2abd5b user: drh tags: propagate-const-opt) | |
