Landed fixes in GCC & Clang for [expr.static.cast]/8 wrong-code bugs when investigating a V8 bug related to it. Previously: enum Flag : bool { kNo, kYes }; static_cast<Flag>(2); // kNo in GCC ❌, kYes in Clang ✅ static_cast<Flag>(0.5); // kNo in GCC and Clang ❌

Gem of my trip to Astorga: Palacio de Gaudí! Beautiful inside out and there is a very interesting epigraph museum in the basement 😇 Cathedral is great too, but if you put it next to Gaudí…😬

Chapel in Palacio de Gaudí, very stunning

Inscription from a 3rd Roman procurator of Hispania Citerior fulfilling his vow to a mix of Greco-Egyptian Serapis + Egyptian Isis + Greek Kore + Greco-Roman/Celtic Apollo Grannus + Roman Mars, and he has two other inscriptions thanking Roman official gods and Nemeses of Smyrna (in Greek). That’s a lot of gods 🤣

Added some new commands to the GDB & LLDB plugin for V8.. `v8 source`: shows the JS source of the selected frame `v8 isolate`: find the isolate address in the current thread, works from the coredump too (implementing that in LLDB was quite a bit of challenge!)

There wasn’t a heatwave in the forecast when I planned my vacation in Burgos but there will be one soon according to the current forecast 😅 Anyways it’s fun to walk around here and see the tomb of El Cid, who was the first Spanish figure I knew (from playing AOE2 when I was a very small kid)!

An impressive dome in the Burgos cathedral

The place where according to legend, El Cid forced Alfonso VI to swear he didn’t assassinate Sancho II - a story that was referenced in AOE2

Made the new debug helper plugins work for Node.js + bleeding edge V8 🌟 Verified it works in LLDB (Linux, macOS) & GDB (Linux), both in live and coredump debugging Going to backport the patches to Node.js when the object inspection is more polished and it stablizes bit more..

Using the plugin, bt in gdb shows the JS source info of JIT-compiled frames, mostly from the CJS loader (without plugin gdb only shows ???)

In the plugin's `v8 inspect` command, it shows the this argument of the first frame is a function named "Module" (the CJS loader class i.e. require('module').Module)

Landed a few improvements to the error reporting for require(esm) with top-level await (behind --experimental-print-required-tla for now): - No longer need to run the code to collect the TLA locations, so it can be enabled by default soon - Added require stack and location metadata to the error

Before: extra noisy arrow pointing to internals, no require stack, needs to run the code to find the top-level await location
After: no more noisy arrows, added require stacks to the output, finds location without running the code

New ERR_REQUIRE_ASYNC_MODULE includes error.requireStack and error.topLevelAwaitLocations metadata properties

Somehow I find myself starving here again, this time sent by an ambulance to the emergency (two very nice people called the ambulance when they saw me in pain after spraining my ankle). Now that I’ve waited past 11pm, maybe I should just go to bed (if I can do that today) on an empty stomach..

A while back when I was sharing my screen my sister asked: why do you programmers use dark backgrounds? Last week I was projecting my terminal/editor to my team and to make it easier to see on the projector screen I switched to light themes. Now I start to wonder why I even use dark themes too 🧐

I re-watched last year Joyee's @webengineshackfest.org talk. I can't recommend it enough. There are many lessons on the require(esm) story. If you want adoption, meet developers where they are, build bridges for them to move to the future you want.

Moving along with the debug_helper-based LLDB & GDB V8 plugins...this now supports basic object inspection! It was fun to write tests that deliberately corrupt the memory and make sure the plugin falls back gracefully, something I've never tried before when maintaining other plugins :D

Landed a set of LLDB & GDB plugins in V8 to help inspect JS states in a live process/coredump together with native states ✨ The initial implementation just supports JS stack trace annotations in bt; support for object inspection is coming up! chromium.googlesource.com/v8/v8.git/+/...

Without the plugin, debugging a coredump from a release build of V8 shows no JS-level information in the stack trace; with the plugin the stack trace is annotated with JS source positions of the functions on the frames.

Joyee Cheung @joyeecheung.bsky.social · 05/05/2026

For those who build or redistribute Node.js - as the V8 implementation of temporal depends on temporal_rs, this also means starting from v26 building Node.js fully requires a Rust toolchain. See github.com/nodejs/node/...
