| 11:22 | If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". check-in: 3da10328 user: drh tags: branch-3.28 | |
| 10:56 | If a query uses an index where one or more of the columns of the index is an expression or a virtual column, and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it.

| 04:44 | Apply considerable acrobatics to get the JS/WASM deliverables building to and loadable from a directory other than the one which contains the app-level code. Requires an only-slightly-leaky abstraction of passing a URL argument when loading sqlite3.js but provides much greater flexibility in where the JS/WASM files are located. check-in: 6d468dab user: stephan tags: trunk | |
| 01:07 | Considerable wasm/js build cleanups and reworking. Remove wasmfs builds from the end-user deliverables and disable the wasmfs build by default, per /chat discussion, as it doubles our deliverable count for only marginal gain. Attempt to move the sqlite3.js/wasm files into subdirectories but rediscovered that that breaks loading in Worker mode because URI resolution of the wasm files differs depending on whether the main script is loaded from a script tag or a Worker. check-in: 5b23e067 user: stephan tags: trunk | |
