fix(runtime): bigint's limb loops build with GCC before 14 (no __builtin_addcll there)richiemcilroy · Oct 11, 2026 feat: bigint, as TypeScript has it: 123n literals, arithmetic, bitwise operators and comparisons, BigInt(x) (try: SyntaxError for a string that isn't an integer, RangeError for a number that isn't), Number(x), int(x) and the sized conversions (trapping when it doesn't fit), toString(radix), BigInt.asIntN/asUintN; mixing with numbers is an error whose fix adds the nrichiemcilroy · Oct 11, 2026 docs: the README's program and media server numbers from today's runs, with json, async_calls and async_tasks (Rust ahead on the async two, by 3 ms and 1 ms), and where Linux results arerichiemcilroy · Oct 10, 2026 docs(bench): npm and Cap media server results from today's runs on macOS and Linux, on Tov's own JavaScriptCore, with where Bun is ahead (npm startup and its memory, the call-heavy loop, and on Linux the media server's startup and memory)richiemcilroy · Oct 10, 2026 docs(bench): every program's results on macOS (M4 Max) and Linux (x86-64, Ryzen 9950X), Rust now in each, and where Tov is behindrichiemcilroy · Oct 10, 2026

fix(bench): the npm benchmark says why a command failed (the load generator's stderr), not just its exit statusrichiemcilroy · Oct 10, 2026

fix(npm): Tov's JavaScriptCore starts with TVInitialize, which makes the thread its contexts run on the engine's main run loop: on Linux the first full collection crashed without one (its timer asks the memory pressure handler, whose own timer goes on the main run loop); rebuild the engine with scripts/jsc/build.shrichiemcilroy · Oct 10, 2026

fix(runtime): a server's sockets are close-on-exec, so a child it starts (ffmpeg, say) doesn't hold its connections or its port: on Linux epoll kept reporting a connection closed here while a child held a copy, and the server used the freed connection (Cap's media server crashed, 'double free or corruption', under /audio/extract); accepted with accept4 there, one syscall instead of threerichiemcilroy · Oct 10, 2026

fix(bench): map_insert's C runs on Linux (strdup, undeclared under -std=c11 with glibc, returned an int and the program crashed)richiemcilroy · Oct 10, 2026

fix(bench): the npm service benchmark waits until the server answers instead of a second (a first run on a fresh machine took longer, and the load found nothing listening)richiemcilroy · Oct 10, 2026
