Fwd: [PHP] proc_open and buffer limit?

I asked this last night on the general mailing list and also have asked around about it. Nobody seems to know. I normally wouldn't ask a support quesiton on a developers mailing list, but nobody else seems to know so I thought that perhaps a developer knows. Why would I be running into this STDIN data size limit when using proc_open? I've tried setting the limits for apache to unlimited in /etc/security/limits.conf just to see if its a system limit. ----- Forwarded message from Mark Krenz <mark@suso.org> ----- Date: Sun, 22 Jan 2006 00:25:33 +0000 From: Mark Krenz <mark@suso.org> To: php-general@lists.php.net Subject: [PHP] proc_open and buffer limit? I'm using PHP 5.1.1 on Apache 2.0.54 on Gentoo Linux. I've been trying to write a program to pass information to a program using proc_open, however when I do, it only passes the first 65536 bytes of the stream and then cuts off the rest. To make sure its not the program I'm trying to send to, I tries using /bin/cat instead and get the same problem. Below, I've included the code that I'm using, which for the most part is from the proc_open documentation page. For testing, I'm reading from a word dictionary which is over 2MB in size. Is there something I'm missing about using proc_open? ------------------------------------------------------------------------- $program = "/bin/cat"; $descriptorspec = array( 0 => array("pipe", "r"), 1 => array("pipe", "w"), 2 => array("file", "/tmp/error-output.txt", "a") ); $cwd = '/var/www'; $env = array('HOME' => '/var/www'); $process = proc_open($program, $descriptorspec, $pipes, $cwd, $env); if (is_resource($process)) { stream_set_blocking($pipes[0], FALSE); stream_set_blocking($pipes[1], FALSE); $handle = fopen("/usr/share/dict/words", "r"); while (!feof($handle)) { $input .= fread($handle, 8192); } fwrite($pipes[0], $input); fclose($handle); fclose($pipes[0]); while (!feof($pipes[1])) { $output .= fgets($pipes[1], 8192); } fclose($pipes[1]); print "<PRE>$output</PRE><BR><BR>\n"; $return_value = proc_close($process); echo "command returned $return_value\n"; } ------------------------------------------------------------------------- -- Mark S.
