after a sequence of repetitive actions i realized the entire nodejs build process (which is largely not the nodejs build process but the v8 build process) is not actually compiling c++ code but instead
(1) generating header files from a combinatorial arrangement of shared stubs
(2) ordering the generated files to maximize the time the c++ compiler takes to iterate over non-matching entries for each #include
(3) directing the c++ compiler to include the maze of generated headers at the top of each source file

so the entire build process is stuck in VFS iteration, intentionally

why would google do this? this issue contains a clue: https://github.com/nodejs/node/issues/62676

but not an easy one! you must search again: https://github.com/nodejs/node/pull/61806#issuecomment-4208315579

Enabling Temporal support requires cargo and rustc, which are new build toolchain requirements.

what is Temporal?

build: enable Temporal by default by richardlau · Pull Request #61806 · nodejs/node

Enabling Temporal support requires cargo and rustc, which are new build toolchain requirements. Add a --v8-disable-temporal-support option to configure.py to explicitly opt-out of Temporal support ...

Temporal does not compile with shared ICU or no ICU · Issue #62676 · nodejs/node

When Node.js is configured with --with-intl=none (or --without-intl) or --with-intl=system-icu the build fails when Temporal is enabled. e.g. --with-intl=system-icu: https://ci.nodejs.org/job/node-...

it's the most fucking obnoxious non-solution to javascript having no fucking integer counter variable in the history of the universe. huge bonus points for this line:

However, some of these concepts may not apply when you are working with another calendar system, such as the Hebrew calendar, the Chinese calendar, the Japanese calendar, etc.

"etc" indeed

Temporal - JavaScript | MDNMDN

The Temporal object enables date and time management in various scenarios, including built-in time zone and calendar representation, wall-clock time conversions, arithmetics, formatting, and more. It is designed as a full replacement for the Date object.

note! https://tc39.es/proposal-temporal/#sec-temporal-calendars

At minimum, ECMAScript implementations must support a built-in calendar named "iso8601", representing the ISO 8601 calendar. In addition, implementations may support any number of other built-in calendars corresponding with those of the Unicode Common Locale Data Repository (CLDR).

sounds like a lot of calendars!

ECMAScript implementations identify built-in calendars using a calendar type as defined by Unicode Technical Standard #35, Part 4, Section 2. Their canonical form is a string containing only Unicode Basic Latin lowercase letters (U+0061 LATIN SMALL LETTER A through U+007A LATIN SMALL LETTER Z, inclusive) and/or digits (U+0030 DIGIT ZERO through U+0039 DIGIT NINE, inclusive), with zero or more medial hyphens (U+002D HYPHEN-MINUS).

but all calendars are still identified in ASCII

Temporal

Introduction The venerable ECMAScript Date object has a number of challenges, including lack of immutability, lack of support for time zones, lack of support for use cases that require dates only or times only, a confusing and non-ergonomic API, and many other challenges. The Temporal set of

they provided a babel plugin that translates a JS big-integer polyfill call into a non-polyfill call to BigInt https://github.com/GoogleChromeLabs/babel-plugin-transform-jsbi-to-bigint

...just so they can avoid having any actual fucking polyfill https://github.com/js-temporal/temporal-polyfill/issues/155

There's a babel plug-in for it, but it would be nice to have a ready-to-import version.
