Omit all use of Expr nodes for TK_AS, as those nodes no longer served a useful purpose and in fact interferred with the query planner. (check-in: 7ab0b258 user: drh tags: trunk)

Experiment with a different fts5 leaf page format that allows faster seeks. (check-in: a1f4c3b5 user: dan tags: fts5-incompatible)

Fix over-length source code lines in Lemon. (check-in: 1efece95 user: drh tags: trunk)

Rename SQLITE_FUNC_VARYING to SQLITE_FUNC_SLOCHNG - a more descriptive name for what that bit means. (check-in: ff5137a6 user: drh tags: index-expr)

Fix a bug in error reporting when a UNIQUE index on expressions fails its uniqueness test. (check-in: 5a2c0e90 user: drh tags: index-expr)
21:16
Not only date/time functions, but also functions like sqlite_version() and changes() need to be prohibited from use inside of indexes. (check-in: 48713130 user: drh tags: index-expr)
19:38
Always assume that indexed expressions can generate a NULL. Get indexed expressions working for the case of two or more expressions in the same index. (check-in: cc60321a user: drh tags: index-expr)

Case should not be significant when comparing function names. (check-in: e2f1caf1 user: drh tags: index-expr)
17:34
Make the distinction between truly deterministic functions and date/time functions which only return the same answer for a single query. Only truly deterministic functions are allowed in indexes. Add new expression index test cases. (check-in: c77554b5 user: drh tags: index-expr)
15:58
Improved analysis and usage of indexed expressions in the query planner. (check-in: f8893696 user: drh tags: index-expr)

Fix the OR-optimization so that it always ignores subplans that do not use an index. (check-in: cf452028 user: drh tags: index-expr)

Fix problems in the indexed-expression handling in the optimizer. (check-in: 03375017 user: drh tags: index-expr)

Add code to maintain indexes with expression arguments across DELETE, INSERT, and UPDATE statements. Legacy tests pass, but the new code paths are still largely untested. The query planner currently makes no effort to use expression indexes. (check-in: efaabdb7 user: drh tags: index-expr)
