Overview
| Comment: | Remove some redundant code: Call sqlite3ResolveExprListNames() rather than calling sqlite3ResolveExprNames() in a loop - in two places. |

| 00:34 | Fix a memory leak that might occur when compiling with SQLITE_OMIT_CHECK. (check-in: 8f1d9f1f user: drh tags: trunk) | |
| 00:27 | Changes toward being able to process indexes on expressions. Not there yet - this check-in is just movement in that direction. Some tests are failing. (check-in: 0ad0f8d7 user: drh tags: index-expr) | |

| 20:21 | Enhances the parser so that it accepts arbitrary expressions for the arguments of an index, though the code generator still rejects everything other than simple column names. The sqlite3RestrictColumnListSyntax() routine is removed since that feature is now handled by the parser. (check-in: bed42116 user: drh tags: trunk) | |
