Treats builtin ops (
op_resources
,op_close
) and js (core.js
,error.js
) as a regularJsRuntime
Extension
that's always loaded (first, see the.insert(0 ...
)This guarantees that
op_close
,op_resources
(andop_print
with #10436) are ready to use afterJsRuntime::new
Though builtins are special, they're not "that special", streamlining them will simplify things like moving JS src off heap generically for all extension provided JS without having to treat
core.js
,error.js
as edge casesNotes
JsRuntime::new
will no longer have anOpId
of 1 since those builtin ops will have taken those slots. I fixed the tests that relied on that assumption and in general it's strongly discouraged to rely on specific OpIds
