636509 - PR_NewTCPSocketPair is hardcoded to use IPv4 on Windows, Symbian, and OS/2

Status: NEW

(NSPR :: NSPR, defect, P5)

Description

[Wan-Teh Chang]

PR_NewTCPSocketPair, used by PR_NewPollableEvent on non-Unix platforms,
is implemented with a pair of IPv4 (AF_INET) TCP sockets on non-Unix
platforms and Symbian.  On Unix PR_NewTCPSocketPair is implemented with
a Unix domain (AF_UNIX) socketpair.

This means on non-Unix platforms (such as Windows and OS/2) and Symbian,
PR_NewTCPSocketPair won't work if the computer doesn't have an IPv4
loopback interface.

The fix is to detect whether the computer has an AF_INET or AF_INET6
loopback interface and select an available address family.  This will
require the new NSPR wrapper function for getaddrinfo proposed in
bug 636504.

Could we fix this using the new API from bug 1769293 ?
