| 23:20 | In ORDER BY LIMIT queries, try to evaluate the ORDER BY terms first, and it it becomes clear that the row will not come in under the LIMIT, then skip evaluation of the other columns. (check-in: c381f0ea57 user: drh tags: trunk) | |
| 22:52 | Fix a branch that has become unreachable due to recent enhancements. (check-in: 81ab5e0d10 user: drh tags: trunk) | |
| 21:51 | Improved security for VACUUM. This check-in combines the fixes of [ab0d99d0b5ede] and [27754b74ddf646] in a way that is less likely to to be broken by future changes. (check-in: 260fc69653 user: drh tags: trunk) | |
| 19:56 | Overhaul of EXPLAIN QUERY PLAN. The output is now in the form of a tree. More details of the query plan are shown, and what is shown is truer to what actually happens. (check-in: ff01bbdabc user: drh tags: trunk) | |
| 19:47 | Optimizations to the new EQP framework. (Closed-Leaf check-in: 956fef361a user: drh tags: rework-EQP) | |
| 16:56 | Fix various error handling conditions on the cell overwrite optimization. Fix a test case so that it works with the new optimization. (check-in: f89b54f414 user: drh tags: cell-overwrite-prototype) | |
| 14:07 | The BtCursor.info fields are only valid if info.nSize!=0. (check-in: 54c537eead user: drh tags: cell-overwrite-prototype) | |
| 13:56 | Add more corruption checking to the cell overwrite logic. (check-in: 58d14afe1e user: drh tags: cell-overwrite-prototype) | |
| 12:57 | Bug fixes in the overwrite optimization. (check-in: 0cb6cd2a6a user: drh tags: cell-overwrite-prototype) | |
| 03:59 | The sqlite3BtreeInsert() routine tries to overwrite an existing cell with modified content if the new content is the same size. Pages are only dirtied if they change. This prototype works some, but still has issues. (check-in: 489451b378 user: drh tags: cell-overwrite-prototype) | |
| 01:37 | Enhance EXPLAIN QUERY PLAN to report the generation of constant rows using VALUES or just a SELECT without FROM. (check-in: c75eee69fa user: drh tags: rework-EQP) | |

| 19:42 | More test case updates. Tests are all running now. (check-in: dab5e52948 user: drh tags: rework-EQP) | |
| 18:00 | Fix test cases so that they work with the new EXPLAIN QUERY PLAN output format. Only some of the cases have been fixed. This is an incremental check-in. (check-in: 5f0e803e33 user: drh tags: rework-EQP) | |

| 15:00 | Prevent VACUUM from running any commands in sqlite_master.sql other than CREATE statements. That is all that should be there anyhow. This fixes a problem discovered by OSSFuzz. Test cases in TH3. (check-in: ab0d99d0b5 user: drh tags: trunk) | |
| 14:24 | Fix a dangling-else problem that was causing recursive CTEs to malfunction. Begin fixing test cases to work with the new EQP output. (check-in: 82ca44b82f user: drh tags: rework-EQP) | |
| 08:12 | Fix a problem in the xBestIndex method of the closure extension causing it to allocate non-contiguous argvIndex values in some cases (an "xBestIndex malfunction" error). (check-in: 0c67150749 user: dan tags: trunk) | |
| 03:03 | Add sqlite3_win32_set_directory8() and sqlite3_win32_set_directory16() functions. (check-in: 6cf0f4e2b4 user: mistachkin tags: branch-3.23) | |

| 18:39 | The SQLITE_ALLOW_SQLITE_MASTER_INDEX compile-time option allows a CREATE INDEX statement against the sqlite_master table. Once created, the index works, and is usable by legacy instances of SQLite. (check-in: 853f316359 user: drh tags: trunk) | |
| 01:18 | The ".selecttrace 0x4000" command causes the AST to be output to stdout as a table with four columns. (Leaf check-in: 2a75e631ee user: drh tags: ast-trace-demo) | |

| 19:32 | Defer loading result column values into registers on an ORDER BY LIMIT until we know that the LIMIT does not exclude the current row. (Closed-Leaf check-in: ce4ef46058 user: drh tags: faster-order-by-limit) | |
|
2018-04-28

| 19:08 | Test cases added for SQLITE_DBCONFIG_RESET_DATABASE. (check-in: 08665a9e2e user: drh tags: trunk) | |
| 18:20 | Fix an RBU problem causing spurious SQLITE_CONSTRAINT errors when restarting an RBU update in which more than one source table writes to a single target database table. (check-in: 564ae8297d user: dan tags: trunk) | |
| 13:21 | Add the SQLITE_DBCONFIG_RESET_DATABASE control for resetting a corrupt database file without closing any database connections. Added the ".dbconfig" command to the CLI. (check-in: a200a49ede user: drh tags: trunk) | |
| 12:43 | Add the SQLITE_DBCONFIG_RESET_DATABASE control as a replacement for the reset_database pragma. Resetting the database should be hard enough to do that it cannot be done by accident. (Leaf check-in: ff836cb8b0 user: drh tags: reset-database) | |
| 11:22 | Merge updates from trunk. (check-in: 94877e495c user: drh tags: reset-database) | |
| 04:16 | Prevent deep recursions on nested COLLATE operators. (check-in: 6e098ee415 user: drh tags: trunk) | |

| 01:48 | Document and expose sqlite3_win32_set_directory() function for use on Win32. (check-in: f677065aab user: mistachkin tags: branch-3.23) | |
| 01:46 | Document and expose sqlite3_win32_set_directory() function for use on Win32. (check-in: 7626b59340 user: mistachkin tags: trunk) | |
| 01:44 | Add comments about the intended use of the sqlite3_data_directory variable as it pertains to the sqlite3_win32_set_directory function. (Closed-Leaf check-in: d11c419756 user: mistachkin tags: win32dir) | |
| 01:37 | Bump the version number to 3.23.2. (check-in: 242dc910b0 user: drh tags: branch-3.23) | |
| 01:27 | Add the "PRAGMA reset_database=ON|OFF" command. When on, it causes the database to appear to be empty, causing the next transaction to reset it to an empty database. (check-in: 02e1a13c1f user: drh tags: reset-database) | |

| 22:42 | Document and expose sqlite3_win32_set_directory() function for use on Win32. (check-in: cbce7180ee user: mistachkin tags: win32dir) | |
| 20:49 | Better comments on the bindvtab.c implementation. All the two-argument version of the .set command. All bindings from .set and -D are still string. (Leaf check-in: 7b2a65a654 user: drh tags: shell-bindings) | |
| 18:05 | Update test script fts3expr4.test so that it always creates fts3 tokenizers in the "en_US" locality. (check-in: 576a8f69ae user: dan tags: trunk) | |
| 17:39 | Add the ability to use bind parameters in the CLI. The new ".set KEY=VALUE" dot-command works to set bindings. Or use the "-Dkey=value" command-line option. Or use the built-in shell_bindings(k,v) virtual table to set, delete, or changing bindings. (check-in: 1f2944d1d6 user: drh tags: shell-bindings) | |
| 16:35 | Fix a test script error causing tests to fail in soak.test. (check-in: 462b52b121 user: dan tags: trunk) | |

| 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: 9fd0faf517 user: drh tags: trunk) | |
| 18:01 | Merge latest changes from trunk. Including the "ORDER BY ... LIMIT" optimization. (check-in: 83a4c9f088 user: dan tags: begin-concurrent-pnu) | |
| 17:54 | Merge latest changes from trunk. Including the "ORDER BY ... LIMIT" optimization. (check-in: d8ae7ba083 user: dan tags: begin-concurrent) | |
| 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: 0fcfc36ceb 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: 71bf91c218 user: dan tags: sorter-limit-opt) | |
| 15:50 | Ensure that new.* values of an UPDATE do not get clobbered after the BEFORE triggers run when unmodified columns of the row being updated are reloaded. Fix for ticket [d85fffd6ffe856092ed8da] (check-in: 0a514e62ad user: drh tags: trunk) | |
| 15:04 | Clarification of the behavior of a BEFORE UPDATE trigger when the trigger changes the values of some of the columns used to compute new columns in the UPDATE. (check-in: 7bb23c2a3d user: drh tags: trunk) | |
