ruby.git/scheduler.c, branch v4.0.2

[DOC] Enhance Fiber::Scheduler docs (#15708)

2025-12-24T00:53:08+00:00

Fewer calls to `GET_EC()` and `GET_THREAD()` (#15506)

2025-12-12T19:47:43+00:00

The changes are to `io.c` and `thread.c`.
I changed the API of 2 exported thread functions from `internal/thread.h` that
didn't look like they had any use in C extensions:

* rb_thread_wait_for_single_fd
* rb_thread_io_wait

I didn't change the following exported internal function because it's
used in C extensions:

* rb_thread_fd_select

I added a comment to note that this function, although internal, is used
in C extensions.

Yield to scheduler if interrupts are pending. (#14700)

Fix `io_pwrite` fiber scheduler hook. (#15428)

2025-12-06T07:35:08+00:00

Fix io_pwrite fiber scheduler hook.

Use `ec->interrupt_mask` to prevent interrupts. (#14588)

2025-09-18T02:24:29+00:00

Disallow pending interrupts to be checked during `FiberScheduler#unblock`.

Ractors can send signals at any time, so the previous debug assertion
can fail if a Ractor sends a signal.
