03:53 AM Revision 37fa88d7 (git): Remove flaky test_escape_html_allocates_same_as_escapeHTML
- It's causing ruby CI to flake, because it's a badly designed test,
a lot of thing can cause acouple extra allocation there and there
so even if you invoke the exact same code twice, you might still
allocate a bit more or a bit less. -

- Add lib/rubygems/vendor/uri to the gem's files so Bundler carries the

09:17 PM Revision bb75c289 (git): ZJIT: Inline String#ascii_only? and #valid_encoding?

on UNKNOWN. Drops the call, ~20% faster on ZJIT. -
- Get rid of the CFUNC overhead in String#ascii_only? and #valid_encoding?. Define them as leaf Primitive.cexpr! builtins in a new string.rb, following the pattern of numeric.rb.

Ruby's GC sweep implementation is currently incremental and lazy. This is to reduce pause times when sweeping. However, the sweep implementation doesn't take advantage of parallelism (multi-core). Sweeping in a GC is not a... -
- By moving the `rb_intern` to the caller, we allow compilers to
precompute the `strlen` part of `rb_intern` which isn't a huge win,
but happens quite a lot as part of Ruby's boot process and when
requiring native gems. -
- Merge it with `rb_define_module_under` to reduce duplication.
-
- Merge it with `rb_define_class_under` to reduce duplication.
-
- By inlining the `rb_intern()` call, we allow it to be replaced
by `rb_intern_const()` which with most compiler will allow to
save the `strlen` call when invoked with a string literal.
This is a small optimization, but during program boo... -
