Replying to myself, the upgrade is not finished yet, but I can confirm that
there is cases where pgwin32_waitforsinglesocket() return and the WSARecv
immediatly fail. I-ve modified the end of pgwin32_recv() :
/* No error, zero bytes (win2000+) or error+WSAEWOULDBLOCK (<=nt4) */
for(;;) {
if (pgwin32_waitforsinglesocket(s, FD_READ | FD_CLOSE | FD_ACCEPT,
INFINITE) == 0)
return -1;
r = WSARecv(s, &wbuf, 1, &b, &flags, NULL, NULL);
if (r == SOCKET_ERROR)
{
printf("SOCKERROR");
if (WSAGetLastError() != WSAEWOULDBLOCK)
{
TranslateSocketError();
return -1;
}
}
else
{
return b;
}
}
The printf("SOCKERROR") line have been hit two times.
Any though ?
Once this upgrade is finished, I will make another try removing FD_ACCEPT from
the pgwin32_waitforsinglesocket() call.
