Changes for version 0.576 - 2026-09-07
- Release Summary
- This release introduces the Sys#pipepair method, which creates a pair of connected, bidirectional anonymous pipes supporting non-blocking I/O. On Unix-like systems, it leverages native socketpair with specified streams, while on Windows, it emulates anonymous pipes using securely named named pipes generated via GUIDs.
- Incompatibe Changes
- Sys#socketpair set FD_CLOEXEC flag on non-Windows.
- New Features
- Add Sys#pipepair method.
- Add Sys::IO#pipepiar method.
