From: jlondon at mail dot mcg dot edu Operating system: Windows NT Server 4.0 PHP version: 4.3.0 PHP Bug Type: IIS related Bug description: Proc_open hangs
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 bug report at http://bugs.php.net/?id=22458&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=22458&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=22458&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=22458&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=22458&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=22458&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=22458&r=support Expected behavior: http://bugs.php.net/fix.php?id=22458&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=22458&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=22458&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=22458&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=22458&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=22458&r=dst IIS Stability: http://bugs.php.net/fix.php?id=22458&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=22458&r=gnused
