| 22:44 | Fix minor OOM problems. (Closed-Leaf check-in: 8b23d80271 user: drh tags: persist-agginfo) | |
| 20:18 | AggInfo objects might be referenced even after the sqlite3Select() function that created them has exited. So AggInfo cannot be a stack variable. And it must not be freed until the Parse object is destroyed. (check-in: 3c840b4df3 user: drh tags: persist-agginfo) | |
| 17:33 | Alternative fix to ticket [c8d3b9f0a750a529]: Prior to deleting or modifying an Expr not that is referenced by an AggInfo, modify the AggInfo to get its own copy of the original Expr. (check-in: 7682d8a768 user: drh tags: persist-agginfo) | |

This change also coincidentally fixes ticket [0899cf62f597d7e7], even thought that was not the issue we were working on at the time. (check-in: 2cddb24e91 user: drh tags: early-winfunc-rewrite-dev) | |
| 14:29 | Fix an assert() failure that could occur if an ORDER BY expression attached to a compound query contains a subquery that (a) is itself a compound query, (b) uses window functions and (c) has an ORDER BY clause that includes another sub-query. (check-in: c96914ea02 user: dan tags: early-winfunc-rewrite-dev) | |
| 13:29 | Avoid no-op calls to sqlite3SelectPrep() when processing sqlite3Select() for subqueries. This simplifies the ".selecttrace" debugging output. (check-in: 3de19ee22a user: drh tags: early-winfunc-rewrite-dev) | |

| 04:01 | In the debugging treeview output, change the name of "SELECT-expr" expression nodes to be "subquery-expr", so as to not confuse them with actual SELECT nodes. (check-in: c1c8937a30 user: drh tags: trunk) | |
| 00:54 | Always use ?...? to indicate optional arguments in the output of ".help" in the CLI. Change ".mode column" so that it automatically activates ".headers on" if headers have not been previously turned on or off. (check-in: 2827c0a186 user: drh tags: trunk) | |

| 14:38 | Space to hold the ".width" of columns in the CLI is now obtained from malloc() and hence is not limited in the number of columns supported. (check-in: 445ed5dab2 user: drh tags: trunk) | |

| 00:45 | When the sqlite_stat1 data is missing for some indexes of a table but is present for the table itself or for other indexes in the same table, then do not let the estimated number of rows in that table get too small, as doing so can deceive the query planner into ignoring a perfectly good index.
