sock v0.2.1 — Go 1.26+ and dependency updates

[hayabusa-cloud]

Introduction

• sock is a zero-allocation socket library for Go, providing TCP, UDP, Unix, SCTP, and raw socket types built directly on the zcall assembly syscall package.

  • All sockets are created with SOCK_NONBLOCK and SOCK_CLOEXEC flags and return iofd.FD file descriptors for integration with io_uring async I/O.
  • Address serialization is zero-allocation, encoding directly into kernel sockaddr structures without intermediate heap objects.

• The package implements an adaptive I/O model (Strike-Spin-Adapt) with network-tuned backoff for deadline-based retry.

Usage

// TCP
conn, _ := sock.DialTCP4(nil, raddr)
n, err := conn.Read(buf)
if err == iox.ErrWouldBlock {
    // Non-blocking — kernel not ready
}

// UDP with batch send
conn, _ := sock.ListenUDP("udp4", laddr)
n, oob, flags, addr, err := conn.ReadMsgUDP(buf, oob)
