| 18:34 | The previous fix for ticket [d85fffd6ffe856092ed8da] in check-in [0a514e62ad1ebe5c12da8dae] did not completely address the probably in that it only worked for cases where the OP_SCopy that loaded the register was the last instruction in the sequence for the expression, which is not necessarily the case for expressions like CASE...END. This revision prevents the registered that will be recomputed from being cached in the first place. check-in: 9fd0faf5 user: drh tags: trunk | |
| 18:01 | Merge latest changes from trunk. Including the "ORDER BY ... LIMIT" optimization. check-in: 83a4c9f0 user: dan tags: begin-concurrent-pnu | |

| 17:43 | When processing an "ORDER BY ... LIMIT" that does not use an index, check whether or not a record may appear in the final result set before adding it to the temp b-tree used for sorting. check-in: 0fcfc36c user: dan tags: trunk | |
| 16:13 | When processing an "ORDER BY ... LIMIT" that does not use an index, check whether or not a record may appear in the final result set before adding it to the sorter. Closed-Leaf check-in: 71bf91c2 user: dan tags: sorter-limit-opt | |

| 18:53 | Fix a problem with processing "LEFT JOIN tbl ON tbl.a = ? AND (tbl.b=? OR tbl.c=?)" in cases where there are indexes on both tbl(a, b) and tbl(a, c). check-in: ce35e39c user: dan 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". To see the original output format, add extra space characters in between words of the initial "EXPLAIN QUERY PLAN". check-in: f53716ee user: drh tags: trunk | |
| 10:57 | Fix a memory leak following failure to open an external CSV file in the csv.c extension. check-in: 526ee07d user: drh tags: trunk | |
| 01:10 | In EXPLAIN QUERY PLAN output, do not show an EXECUTE LIST SUBQUERY line for IN operators where the RHS is a list and not a subquery, since in that case there is no SUBQUERY to execute. check-in: 8bc0207a user: drh tags: trunk | |

| 17:43 | The ".selecttrace 0x2000" command causes just the top-level parse tree to be displayed, after all transformations, and showing the EQP iSelectId at each level. check-in: ca34c2dd user: drh tags: trunk | |
| 17:18 | The ".selecttrace 4" command now shows only a single parse tree after name resolution. check-in: 5682146e user: drh tags: trunk | |
| 17:09 | Do not restore the iSelectId value until after the last SELECTTRACE when debugging Select processing. check-in: 8088d8ca user: drh tags: trunk | |
