| 14:28 | If a subquery is used to drive an index, this change avoids making an extra copy of the result of that subquery. But, such situations are probably sufficiently unusual that the added complexity of this enhancement is not worth the performance gain. So I'm going to park this check-in on a branch. If we later find a use case to justify it, we can merge it to trunk then. This is the "further change" that was promised by the prior check-in comment. (Leaf check-in: 4488cb883e user: drh tags: copy-optimization) | |

If an error is found while analyzing a subquery expression, change the expression to TK_ERROR so inhibit further processing on that expression. dbsqlfuzz cf624b8c0484c66e0f552bf6475e3e3f2c22b24e.

Actually making this work, though, will involve a lot more code which will likely slow down processing for the common case where there is no RETURNING clause.

Instead, put such functions in an OP_Once block. This fixes ticket [3c9eadd2a6ba0aa5] and causes COALESCE() and CASE...END to be short-circuit. (check-in: c5f96a085d user: drh tags: trunk) | |

| 16:46 | Rework this changes so that instead of setting the WhereTerm.truthProb when a term is seen to be of low selectivity, it merely sets a new flag (the TERM_HIGHTRUTH flag) which causes whereLoopOutputAdjust() to ignore that term.

| 19:59 | Add support for "ORDER BY ... NULLS FIRST" and "ORDER BY ... NULLS LAST". Use this to fix ticket [f8a7060e]. (check-in: 94085fb3e7 user: dan tags: trunk) | |
| 17:59 | The ALWAYS() added by the previous check-in was incorrect. Take it back out. (check-in: 336235db2b user: drh tags: trunk) | |
| 17:28 | Add ALWAYS() to an always true conditional that results from the previous check-in. Add a test case for ticket [dbaf8a6820be1ece] to supplement those already checked into TH3. (check-in: aff2098047 user: drh tags: trunk) | |
| 17:01 | Omit the "x IN (y)" to "x==y" optimization of check-in [e68b427afbc82e20] (and ticket [e39d032577df6942]) as it causes difficult affinity problems as demonstrated by ticket [dbaf8a6820be1ece] and the original assertion fault is no longer a factor due to countless other changes of the previous 5 years. (check-in: 7f5168a76a user: drh tags: trunk) | |

| 16:12 | Simplification of the WHERE loop code generator for NULLS LAST saves a few CPU cycles and about a hundred bytes of code space. (check-in: e3ed2f496f user: drh tags: nulls-last) | |
| 13:32 | Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls. This enables the re-do jump at the bottom of the loop to be coded with a single OP_IfNotZero opcode, rather than a sequence of OP_If, OP_Integer, OP_Goto.

| ||
| 23:23 | When the query planner has the opportunity to use an IN operater constraint on a term of an index other than the left-most term, use the estimated number of elements on the right-hand side of the IN operator to determine if makes sense to use the IN operator with index lookups, or to just do a scan over the range of the table identified by the index terms to the left. Only do this if sqlite_stat1 measurements are available as otherwise the performance estimates will not be accurate enough to discern the best plan. Bias the decision slightly in favor of using index lookups on each element of the IN operator. (check-in: 2cbbabdf5e user: drh tags: trunk) | |

| 13:07 | Enhance the CLI to render EXPLAIN QUERY PLAN using an ASCII-art graph. This works with ".eqp" modes and when the query begins with exactly "EXPLAIN QUERY PLAN".

| 23:28 | I was a little concerned about this check-in. Though I could not generate a failure myself, I thought it was risky. I checked it in for further testing. Then, overnight, OSSFuzz found a failure case for me. So the change is now moved out into a deadend branch. Was: Use OP_SCopy rather than OP_Copy to transfer results from a co-routine to its consumer. This undoes an earlier fix for ticket [98825a79ce] by check-in [ec6a06246e] because that problem no longer occurs due to WHERE clause push-down.
