| 22:12 | Performance improvement: Avoid using sqlite3WalkerSelectExpr() and sqlite3WalkerSelectFrom() twice, so that the compiler will in-line their implementation. (Closed-Leaf check-in: 2b9258b8 user: drh tags: ticket-f09fcd17810f) | |

| 19:56 | New test case that still hits an assertion fault, just to prove that the previous checkin merely made the problem more obscure and did not completely fix it. (check-in: a9a3b532 user: drh tags: ticket-f09fcd17810f) | |
| 19:15 | Simplify the query flattener so that it does not duplicate the WHERE clause of subquery that is being incorporated into the outer query - copies it directly. This is more efficient. And it also fixes the specific test case show for ticket [f09fcd17810f65f71789525] but it does not resolve the more general problem that sqlite3ExprDup() does not correctly duplicate expressions that contain subqueries with window functions. (check-in: f1b18d44 user: drh tags: ticket-f09fcd17810f) | |

| 14:24 | Bump the version number to 3.26.1. (check-in: e97e053b user: drh tags: branch-3.26) | |
| 14:11 | Fix a potential NULL pointer dereference that can occur in ALTER TABLE following an OOM. Test case in TH3. (check-in: 99a0951f user: drh tags: branch-3.26) | |
| 13:57 | Ensure that ALTER TABLE modifies table and column names embedded in WITH clauses that are part of views and triggers. (check-in: e066b4e1 user: drh tags: branch-3.26) | |
| 03:59 | Invoking the sqlite3_trace() or sqlite3_trace_v2() interfaces cancels any sqlite3_profile() that is running. (check-in: ec63d350 user: drh tags: trunk) | |
| 03:13 | Merge fixes from trunk. (check-in: f2083ee4 user: drh tags: begin-concurrent-pnu) | |
| 02:08 | Merge bug fixes from trunk. (check-in: 1e13aaa2 user: drh tags: begin-concurrent) | |

| 01:53 | Fix a potential NULL pointer dereference that can occur in ALTER TABLE following an OOM. Test case in TH3. (check-in: ea50815b user: drh tags: trunk) | |
| 01:08 | Fix a missing mutex in the sqlite3_normalized_sql() interface when it is called on a prepared statement that did not previously have a computed normalization of the input SQL. (check-in: 1a1a59c6 user: drh tags: trunk) | |
| 00:08 | Merge ALTER TABLE and sqlite3_normalized_sql() bug fixes from trunk. (check-in: 3793e5d5 user: drh tags: begin-concurrent-pnu) | |
| 00:05 | Merge ALTER TABLE and sqlite3_normalized_sql() fixes from trunk. (check-in: acf10b3f user: drh tags: begin-concurrent) | |

2018-12-05

| 23:56 | Get rid of the hash table used to track IN operators in the sqlite3_normalized_sql() implementation. Use simple integer variables instead. (check-in: 272dc74f user: drh tags: trunk) | |
| 23:45 | The sqlite3_normalized_sql() interface should not be transforming quoted identifier names into wildcards. Fix this, and at the same time simplify the code substantially. (check-in: e8540377 user: drh tags: trunk) | |
| 23:25 | Bungled checkin. Ignore. (Closed-Leaf check-in: 9b6e9a6e user: drh tags: mistake) | |

| 13:39 | Enhance the sqlite3_normalize_sql() interface so that it works even if the prepared statement was not initially compiled using SQLITE_PREPARE_NORMALIZED. Enhance the ".trace" command in the CLI so that it is able to access the full scope of functionality provided by sqlite3_trace_v2() and in particular so that it is able to show normalized SQL output using the newly enhanced sqlite3_normalize_sql() interface. (check-in: 7da617e9 user: drh tags: trunk) | |

| 21:16 | When compiled with SQLITE_ENABLE_NORMALIZE, always have sqlite3_exec() enable the SQLITE_PREPARE_NORMALIZE flag. (Leaf check-in: 28643d83 user: mistachkin tags: execWithNormalize) | |
| 19:41 | First attempt at making features work together. Only the most minimal testing so far. (check-in: fd707001 user: dan tags: begin-concurrent-wal2) | |
