| 01:35 | Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine. This is a stop-gap means of controlling the decision to manifest while we try to work out a better to make that decision automatically. (check-in: a29e117d7e user: drh tags: trunk) | |

This involves a rewrite of the implementation of the CAST operator. (check-in: 91d8a8d0b7 user: drh tags: trunk) | |

| 23:33 | Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine into two with the second routine named sqlite3BtreeCursorRestore(). The first now only reports whether or not the cursor has moved and the second tries to restore the cursor. This allows the sqlite3VdbeCursorMoveto() routine to be refactored to avoid stack pointer movements, for a noticable performance gain. (check-in: ce123b5c59 user: drh tags: trunk) | |

| 20:37 | Clarify the computation of compatible isOrdered by in the plan solver of the query planner. (Closed-Leaf check-in: b5e8fd575a user: drh tags: query-planner-fix) | |
| 20:25 | Remove the extraneous debugging printf() from the previous check-in. (check-in: 8f04d2c008 user: drh tags: query-planner-fix) | |
| 16:50 | Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm.

| 18:50 | A couple more harmless compiler warnings eliminated. (check-in: bcf6d775f9 user: drh tags: trunk) | |
| 17:49 | Fix two more harmless compiler warnings. Make sure the fts3_unicode2.c file is in sync with mkunicode.tcl. (check-in: a2a60307ea user: drh tags: trunk) | |
| 14:36 | Fix harmless compiler warnings. In the command-line shell, report if the ".system" command returns a non-zero result. (check-in: 1202e9771f user: drh tags: trunk) | |
| 11:58 | Fix an obsolete comment in the func.c source file. No changes to code. (check-in: 5c6bb57d90 user: drh tags: trunk) | |
| 11:57 | On the windows VFS, do not try to make InterlockedCompareExchange an overloadable function, since sometimes it is a macro. (check-in: ab1a751e13 user: drh tags: trunk) | |
| 11:49 | Fix an obsolete comment in the func.c source file. No changes to code. (check-in: 7a145c9409 user: drh tags: sessions) | |
| 03:06 | In the Win32 VFS, work around InterlockedCompareExchange() being a macro on some platforms (e.g. x64). (check-in: 7be244ce12 user: mistachkin tags: trunk) | |
| 02:03 | Merge all recent changes from trunk. (check-in: a353a8515f user: drh tags: threads) | |
| 01:08 | Fix typos in the opcode documentation. Comment changes only. No changes to code. (check-in: 717245d487 user: drh tags: trunk) | |
| 00:29 | A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. (check-in: 0ad1ed8ef0 user: drh tags: trunk) | |
