Re: Patch that corrects non blocked socket reading on WIN32

I think the code itself should be fixed (with #ifdef or add it to the socket abstraction). It's dangerous to redefine errno because other code uses it too. Andi At 01:01 PM 1/14/2001 -0800, Christophe Thibault wrote:

I just came across a bug still present in the latest php 4 release. 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 and now it works like a charm :) please submit my patch to the cvs server so i can benefit of it in the next php releases bye, -christophe -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: php-dev-unsubscribe@lists.php.net For additional commands, e-mail: php-dev-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
