12:36 AM Feature #21981 (Open): Remove CREF rewriting for methods on cloned classes/modules
- When a class or module is cloned, Ruby currently rewrites the CREF chain of each copied method so that it points at the new class instead of the original. I don't think this should happen, and methods on a cloned class should retain thei...

11:27 PM Revision a6c6e563 (git): Fix random timeout in test_thread_join_during_finalizers on Windows (#16650)

timeout from 30s to 60s. Process creation is expensive on Windows, and
the combination caused the test to exceed the 30s limit on Windows CI. -
- The default limit of 2.0 is too tight for RSS measurements on macOS,

- This gets rid of the copying of the entire opt_table in
function_stub_hit() since it only reads one element. HIR builder
still does a copy and that's unchanged. It needs to read the whole

02:40 PM Revision f0f92435 (git): Use ubuntu-latest for macOS result jobs
- The result jobs in macOS workflows only check if other jobs failed
(just runs `exit 1`). They don't need macOS runners. Using
ubuntu-latest instead frees up macOS runner slots and starts faster
due to shorter queue times. -
- Move compilation steps from the heaviest jobs to the lightest to reduce
the critical path of the Compilations workflow.
