| 16:03 | Query planner tuning: When deciding between two plans with the same cost, bias the selection toward the one that does not use the sorter. (check-in: f0ec36d4 user: drh tags: trunk) | |
| 13:31 | Make sure enough memory is allocated for pathological quoting cases when computing a quoted table name in the command-line shell. (check-in: 0583b84a user: drh tags: trunk) | |
|

| 15:47 | When generating individual loops for each ORed term of an OR scan, move any constant WHERE expressions outside of the loop, as is done for top-level loops. (check-in: 712267c9 user: dan tags: trunk) | |

| 16:51 | When generating individual loops for each ORed term of an OR scan, move any constant WHERE expressions outside of the loop, as is done for top-level loops. (Closed-Leaf check-in: e4a022be user: dan tags: or-optimization) | |
|
2017-06-21
| ||
| 01:36 | Enable pragma virtual tables for the integrity_check, quick_check, and foreign_key_check pragmas. (check-in: 118f7bb3 user: drh tags: trunk) | |
|

| 18:19 | Rename the azCompileOpt global constant to avoid a harmless compiler warning about a name conflict with a local variable. (check-in: 94e420ec user: drh tags: trunk) | |
| 17:43 | Ensure that the query planner knows that any column of a flattened LEFT JOIN can be NULL even if that column is labeled with "NOT NULL". Fix for ticket [892fc34f173e99d8]. (check-in: 48346268 user: dan tags: trunk) | |

| 11:44 | Experimental "PRAGMA secure_delete=FAST" pragma. The intent is to overwrite deleted content with zeros without increasing the amount of disk I/O. (Closed-Leaf check-in: f1682f0f user: drh tags: fast-secure-delete) | |

| 19:06 | Avoid adding an artifical "LIMIT 1" on scalar subqueries that do not need it. This seems like a pointless optimization as it makes minimal run-time difference but does increase code complexity. Parked on a branch for historical reference. (Leaf check-in: c21628e9 user: drh tags: subquery-limit-opt) | |
| 18:49 | Fix a missing comma in the previous check-in. (check-in: f3db02f4 user: drh tags: trunk) | |
| 17:55 | Rework the code in ctime.c a bit to report on more compile time options. And to only output configuration options passed in to SQLite, not the default values of #define symbols set automatically. Also generate the large array in ctime.c using new script tool/mkctime.tcl, instead of entering it manually. (check-in: 9a443397 user: dan tags: trunk) | |
| 17:29 | Ensure that the value of the THREADSAFE symbol is always included when reporting compile time options, even if it was not explicitly configured. (Closed-Leaf check-in: 95141c64 user: dan tags: ctime-refactor) | |
