Overview
| Comment: | Always use nanosleep() (instead of usleep() or sleep) if the _POSIX_C_SOURCE macro says it should be available. See Fossil Forum post ab2e2593ae307946 for driver behind this enhancement. |

| 18:21 | Rename some JS files from X.js to X.c-pp.js to keep the maintainer, and downstream build customizers, aware that those files contain constructs specific to the c-pp preprocessor and will not run as-is in JS. (check-in: 2eade7c7 user: stephan tags: trunk) | |

| 11:50 | Install sqlite3_malloc/sqlite3_free() as the JS-side WASM allocator (as opposed to replacing C-level's malloc()/free() with them). All tests work and this eliminates the potential for allocator discrepancies when using the (de)serialize APIs. (check-in: 95c78f6b user: stephan tags: trunk) | |
