Changes In Branch fast-secure-delete Excluding Merge-Ins
This is equivalent to a diff from f3db02f490 to f1682f0faf

| 20:06 | Add the "PRAGMA secure_delete=FAST" option, which overwrites most deleted content without increasing the amount of I/O. Deleted content might persist on the free page list, however. And extra CPU cycles are used for zeroing, of course. (check-in: 38978ce65b 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: 483462682d 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: f1682f0faf 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 Parked on a branch for historical reference.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: c21628e9c1 user: drh tags: subquery-limit-opt) | |
| 18:49 | Fix a missing comma in the previous check-in. (check-in: f3db02f490 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: 9a443397a6 user: dan tags: trunk) | |
