devel/ruby-io-event 1.22.0 NetBSD

1.22.1 (2026-09-23) * Fix an infinite loop in the ready queue flush when a queued fiber is resumed out of band, e.g. by a stale unblock racing a timeout, while another fiber re-queues itself on every iteration. * Preserve each ready queue flush's boundary with its own placeholder so newly queued fibers are deferred even when earlier entries are removed. Nested native flushes skip other placeholders, processing work queued before their own boundary. Native selectors ignore placeholders when checking readiness and remove them if a fiber raises.

1.22.0 (2026-09-10) * Reject non-finite timer times (NaN and positive or negative infinity), preventing invalid heap ordering and permanently retained timer handles.

1.20.0 (2026-08-26) Add compatibility with Ruby 4.1's fiber scheduler interface version 4. Buffered IO operations now use (offset, length), perform a single transfer of at most length bytes, return short transfers directly, and report -EAGAIN without waiting. Earlier Ruby versions retain the existing minimum-progress behavior. 1.20.1 (2026-08-26) * Fix io_uring scheduler v4 compilation. (#214) 1.21.0 (2026-08-26) * Handle interrupted io_uring process waits. (#215) 1.21.1 (2026-08-27) * Fix the URing completion free-list empty check so its sole entry can be reused instead of unnecessarily allocating a new completion. * Keep cancelled URing completion records allocated until both the operation and cancellation completions have been processed.

1.19.5 (2026-08-14) * Preserve the original exception or non-local control flow when IO::Event::WorkerPool cancellation interrupts a blocked fiber, while still cancelling and draining the in-flight blocking operation before returning control to Ruby.

1.19.4 (2026-07-27) * Capture errno immediately after epoll_wait / kevent, preventing stale or subsequently clobbered values from raising a spurious Errno::* when a native selector wait is interrupted or skipped.
