| 23:56 | • Fixed ticket [40812aea]: Incorrect result for comparison of large number plus 6 other changes (artifact: 0dea4a6a user: drh) | |
| 23:56 | When the affinity of a table column is INT or REAL, make the affinity of corresponding index columns NUMERIC. This increases the precision of index lookups for large numbers so that it matches the precision of ordinary comparison operators. Ticket [40812aea1fde9594] (check-in: e0d909c7 user: drh tags: trunk) | |
| 23:15 | • Fixed ticket [5a3dba81]: REINDEX causes "UNIQUE constraint failed" error plus 6 other changes (artifact: fedacb2d user: drh) | |
| 23:15 | Make sure OP_RealAffinity has been applied to all columns of type REAL in the excluded.* pseudo-table of an UPSERT. Ticket [5a3dba8104421320] (check-in: 67381dad user: drh tags: trunk) | |
| 21:52 | Improvements to VDBE tracing. No changes to code in normal deliverables. (check-in: 54553bf1 user: drh tags: trunk) | |
| 20:28 | • New ticket [40812aea] Incorrect result for comparison of large number. (artifact: 8188b7b4 user: mrigger) | |
| 19:45 | Add test case to window8.test. Also fix an error in a comment in window.c. (check-in: 2925bfa5 user: dan tags: trunk) | |

| 18:02 | Back out the change at [47cd634c98b502d4] which was incorrect. Add a test case so that we don't accidently back out that change again. (check-in: 596ac2a4 user: drh tags: trunk) | |
| 17:28 | Add further comments to window.c. (check-in: 90046456 user: dan tags: trunk) | |

| 16:14 | Fix a bug in RANGE window functions that use "ORDER BY <expr> DESC NULLS FIRST" as the window-frame ORDER BY clause. (check-in: 39b4cad4 user: dan tags: trunk) | |
| 16:01 | • Fixed ticket [f8f472cb]: Partial index and BETWEEN issue plus 6 other changes (artifact: 03079b14 user: drh) | |
| 16:00 | The expression "(X IS FALSE) IN (FALSE)" does not imply that X is NOT NULL. Ticket [f8f472cbc77ba9c9] (check-in: dd661348 user: drh tags: trunk) | |
| 15:43 | • New ticket [f8f472cb] Partial index and BETWEEN issue. (artifact: bac71624 user: mrigger) | |
| 15:11 | • Fixed ticket [fba33c8b]: Partial index causes row to not be fetched in BETWEEN expression plus 6 other changes (artifact: 9f4bc62d user: drh) | |
| 15:11 | The expression "(X IS FALSE) BETWEEN FALSE AND TRUE" does not implie that X is not NULL. Ticket [fba33c8b1df6a915] (check-in: 057fb8b1 user: drh tags: trunk) | |
| 14:33 | • New ticket [fba33c8b] Partial index causes row to not be fetched in BETWEEN expression. (artifact: aa648476 user: mrigger) | |
| 13:07 | • Fixed ticket [a6408d42]: Partial index causes row to not be fetched plus 6 other changes (artifact: 8b2e986d user: drh) | |
| 13:07 | The expression "(x IS FALSE) IS FALSE" does not imply that X is not NULL. Ticket [a6408d42b9f44462] (check-in: 45ff2b1f user: drh tags: trunk) | |
| 11:33 | • New ticket [a6408d42] Partial index causes row to not be fetched. (artifact: ba5257e3 user: mrigger) | |

| 20:03 | Test the schema after renaming a table. Ensure that temp database triggers and views are updated when renaming a column. (check-in: f3c27d91 user: dan tags: alter-table-rename-table) | |
| 18:53 | Give the debugging routine print_pager_stats() external linkage in order to suppress harmless compiler and TSAN warnings. (check-in: ff4dc082 user: drh tags: trunk) | |
| 16:26 | Fix an ALTER TABLE problem with processing temp schema views and triggers. (check-in: 72cfb1be user: dan tags: alter-table-rename-table) | |

| 22:15 | Provide hints to the btree layer during the creation of transient tables for when it is possible for those tables to use a hash rather than a binary tree. No use is currently made of those hints, though assert() statement verify their accuracy. (check-in: 4fead8e7 user: drh tags: trunk) | |
