#22458 [Opn->Fbk]: Proc_open hangs

ID: 22458 Updated by: wez@php.net Reported By: jlondon at mail dot mcg dot edu -Status: Open +Status: Feedback Bug Type: IIS related Operating System: Windows NT Server 4.0 PHP Version: 4.3.0 New Comment: Please try using the following for the command string: "C:\\php\\cli\\php.exe" Previous Comments: ------------------------------------------------------------------------ [2003-02-27 10:30:32] jlondon at mail dot mcg dot edu No change...still runs like mad and crashes IIS. I can't even do a "net stop". I'm running the CGI version if that makes any difference. Also I have to refer to php as c:/php/php otherwise error-output.txt has the message "he name specified is not recognized as an internal or external command, operable program or batch file." ------------------------------------------------------------------------ [2003-02-27 08:51:50] iliaa@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip ------------------------------------------------------------------------ [2003-02-27 08:26:25] jlondon at mail dot mcg dot edu proc_open hangs on the example that is in the manual. Here is the code. $descriptorspec = array( 0 => array("pipe", "r"), // stdin is a pipe that the child will read from 1 => array("pipe", "w"), // stdout is a pipe that the child will write to 2 => array("file", "c:/temp/error-output.txt", "a"), // stderr is a file to write to ); $process = proc_open("c:\php\php.exe", $descriptorspec, $pipes); if (is_resource($process)) { // $pipes now looks like this: // 0 => writeable handle connected to child stdin // 1 => readable handle connected to child stdout // Any error output will be appended to /tmp/error-output.txt fwrite($pipes[0], "<?php echo \"Hello World!\"; ?>" . chr(3)); fclose($pipes[0]); while(!feof($pipes[1])) { echo fgets($pipes[1], 1024); } fclose($pipes[1]); // It is important that you close any pipes before calling // proc_close in order to avoid a deadlock $return_value = proc_close($process); echo "command returned $return_value\n"; } I'm running NT4 Server/PHP4.3.2.2/IIS4. This bit of code opened up 54 php.exe/cmd.exe (that's 54 of each or 108 total) processes on my machine. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22458&edit=1
