Not really, because things like
packedFD="0x0e00000073c6e946"
converted to a long long breaks sendfdport etc.
Truncating to 4 bytes seems to work:
patch at the end of twext.python.sendfd.recvfd:
---
unpackedFD = 0
int_size = calcsize("i")
log.debug(str('recvfd: socketfd=%d, data="%s", flags=0x%s, cmsg_level=0x%s,
cmsg_type=0x%s, packedFD="0x%s"'
% (socketfd, data, hex(long(flags)), hex(long(cmsg_level)),
hex(long(cmsg_type)), packedFD.encode('hex_codec'))))
if len(packedFD) != int_size:
err_msg = str("recvfd: packedFD [%d] not %d bytes long" %
(len(packedFD),int_size))
log.warn(err_msg)
if len(packedFD) > int_size:
[unpackedFD] = unpack("i", packedFD[0:int_size])
log.warn('recvfd: Truncating packedFD to %d bytes: %d.' %
(int_size, unpackedFD))
else:
raise ValueError(err_msg)
else:
[unpackedFD] = unpack("i", packedFD)
return (unpackedFD, data)

At least this shows to me, that shipping FDs via AF_UNIX sockets works.
To find the real bug, I need advice.
