Bug description: read() buffer memory not freed
Using the following code:
<?
/* Allow the script to hang around waiting for connections. */
set_time_limit (0);
##### Connect to DB
mysql_connect('localhost','chatscript','jen481');
##### Open log file
$fp=fopen('chat_log','a');
$outMsgHeader="HTTP/1.1 200 OK\r\nDate: ";
$outMsgAfterDate=" GMT\r\nServer: PHP\r\nConnection: close\r\nTransfer-Encoding:
chunked\r\nContent-Type: text/html\r\n\r\n";
$outMsgFooter="\r\n\r\n";
$sock=open_listen_sock(1089);
if ($sock<0)
{
echo "socket() failed: reason: " . strerror ($sock) . "\n";
exit;
}
if (($ret = listen ($sock, 5)) < 0)
{
echo "listen() failed: reason: " . strerror ($ret) . "\n";
shutdown($sock,2);
exit;
}
do
{
if (($msgsock = accept_connect($sock)) < 0)
{
echo "accept_connect() failed: reason: " . strerror ($msgsock) . "\n";
shutdown($sock,2);
exit;
}
$ret=read($msgsock,$buf,2048);
$isPost=strpos($buf,'POST');
if ($isPost===false)
{
$isGet=strpos($buf,'GET');
if ($isGET===false)
{
write($msgsock,' HTTP/1.1 405\r\n',13);
}
else
{
$startQS=strpos($buf,'?')+1;
$endQS=strpos($buf,' ',$startQS);
$lenQS=$endQS-$startQS;
$QS=substr($buf,$startQS,$lenQS);
}
}
else
{
do
{
$ret=read($msgsock,$buf,2048);
if (substr($buf,0,15)=="Content-length:")
{
$conLen=substr($buf,16);
}
} while ($buf != "\n");
// through with headers, now get actual content
$ret=read($msgsock,$buf,$conLen);
// $buf now contains the query string
$QS=$buf;
}
$msgToSend=urlencode(procMsg($QS));
$msgLen=dechex(strlen($msgToSend));
$sendDate=gmdate('D, d M Y H:i:s');
$send=$outMsgHeader.$sendDate.$msgLen."\r\n".$msgToSend.$outMsgFooter;
write($msgsock,$send,strlen($send));
$log=$sendDate."\t".$QS."\t".$msgToSend."\n";
fwrite($fp,$log);
close ($msgsock);
} while (true);
?>
(The function procMsg() is not relevent as for bug testing is set to return 'test')
Running this script causes memory to be consumed and not released with each
connection. I've narrowed the problem down to the read() function as I can affect the
rate of memory consumption by modifying the length argument. Evidently the buffer is
not freed.
