Message 332389 - Python tracker (original) (raw)

Python builds on MacOS do not expose the IPV6_RECVPKTINFO flag specified in [RFC3842], which is required for UDP protocols that need control over their servers' sending ports like CoAP.

While I don't own Apple hardware and thus can't test it, the nginx code indicates that this API is available on OSX and is just gated behind -D__APPLE_USE_RFC_3542. Searching the web for that define indicates that other interpreted langues and applications use the flag as well (PHP, Ruby; PowerDNS, nmap, libcoap).

Please consider enabling this on future releases of Python on OSX.
