| 14:59 | Deleted: Merge the latest enhancements from trunk. (check-in: [7c328e8894] user: drh branch: begin-concurrent, size: 0) | |
|
2019-04-05
| ||
| 20:56 | Deleted: Eliminate the tool/addopcodes.tcl script. The purpose of that script was to keep the number of parser codes below 256 in order to save parser table space. But we have long since blown through that ceiling so the addopcodes.tcl script was just needless complexity. There is no longer any reason to keep it around.

| 00:36 | [6ea8e01bd7] part of check-in [bad4d7a0d9] Attempt to optimize the resolveExprStep() routine by mapping Expr opcodes into a subset of opcodes that resolveExprStep() cares about and only calling the routine when those opcodes are encountered. Is slightly faster, but it seems like the very slight performance bump is not worth the added complexity. Saved on a dead-end branch for historical reference.

| 19:41 | [ffa614f3ea] part of check-in [a52ef2ad7c] Proof of concept for the ability to use the expression columns in an index on expressions in place of equivalent expressions in the result set or in the WHERE clause.

| 15:36 | [10c889c4a6] part of check-in [b40b202c1f] Since the TK_VECTOR token is not actually used by the parser, make it an extra token code added by the tool/addopcodes.tcl script during parser build. (check-in: [b40b202c1f] user: drh branch: rowvalue, size: 1510) | |
