Bug description: non blocking sockets reading doesn't work on WIN32
i have the following script:
$g_ssock=fsockopen($server,$port,$errno,$errstr,30);
socket_set_blocking($g_ssock,0);
while(!feof($g_ssock))
echo fgets($g_ssock,4096);
if you uncomment the socket_set_blocking line it will work fine on win32, but with non blocking
sockets, feof will always return true. by digging through the code, it appears that fsock.c uses
the errno() function for determining any socket error as seen in function php_sockread_internal:
} else if(nr_bytes == 0 || (nr_bytes < 0 && errno != EWOULDBLOCK)) {
sock->eof = 1;
}
the problem is that win32 doesn't report socket errors with _errno() but with WSAGetLastError()
so here is my fix:
in fsock.c, line 46, replace:
#ifdef PHP_WIN32
#include <winsock.h>
#else
with:
#ifdef PHP_WIN32
#include <winsock.h>
#undef errno
#define errno (WSAGetLastError())
#else
