| 15:53 | Renamed the SQLITE_SHELL_WASM_WEB_MODE to SQLITE_SHELL_FIDDLE, which seems to be more in line with project convensions and indicates that that flag is only intended for /fiddle mode, as opposed to arbitrary wasm-on-the-web use. (check-in: d1d019bf user: stephan tags: trunk) | |

| 09:40 | Renamed SQLITE_SHELL_WASM_MODE to SQLITE_SHELL_WASM_WEB_MODE and no longer automatically enable it if __EMSCRIPTEN__ is defined, in order to facilitate using Emscripten to build the shell for CLI-based WASM runtimes (which cannot make use of the web-specific user input changes). The fiddle build now explicitly passes the new flag on at compile-time. (check-in: ee059ad5 user: stephan tags: trunk) | |
| 07:13 | Back out the pager performance enhancement at [a1c090e08139f99d3], because it turns out we should never allow a zero key into the pcache interface according to the design specs, even if that page is immediately released without ever being used.

| 18:18 | wasm: lots of doc additions and refactoring. Refactored the WASM memory heap usage to hopefully eventually account for a runtime-growable heap. Differentiate between supported TypedArray types for input SQL strings vs binding/fetching blobs. Might (untested) have implemented the ability to bind UtfNNArray values as blobs, where NN is one of 16 or 32. (check-in: e10d57df user: stephan tags: wasm-cleanups) | |
