| 20:06 | Fixes to the logic for constraint check reordering during upsert. Improved comments on constraint check bytecode. Add an assert that prevents the same label from being resolved more than once. (check-in: 1ddbb0ff55 user: drh tags: upsert) | |
| 19:29 | During PRAGMA vdbe_addoptrace=ON, show calls to sqlite3VdbeResolveLabel() in the debugging output. (check-in: 9ff07a06ce user: drh tags: upsert) | |
| 18:50 | TK_REGISTER expressions nodes are probably not constant. Make sure sqlite3ExprIsConstant() knows this. (check-in: f3d91cad92 user: drh tags: upsert) | |
