#39198 [Com]: is_dir seem to have permission problems

ID: 39198 Comment by: legolas558 at users dot sourceforge dot net Reported By: php dot spam at frogblender dot net Status: No Feedback Bug Type: Directory function related Operating System: Windows 2003 PHP Version: 5.1.6 New Comment: The problem seems affecting only the temporary directory's subdirectories; please fix this bug because it is causing a lot of weird effects on scripts which verify paths existance and eventually create them. I am using PHP 5.2.0 and running this script: <?php // bug #39198 testcase, see http://bugs.php.net/bug.php?id=39198 // @author legolas558 if ( !function_exists('sys_get_temp_dir') ) { // Based on http://www.phpit.net/ // article/creating-zip-tar-archives-dynamically-php/2/ function sys_get_temp_dir() { // Try to get from environment variable if ( !empty($_ENV['TMP']) ) return realpath( $_ENV['TMP'] ); else if ( !empty($_ENV['TMPDIR']) ) return realpath( $_ENV['TMPDIR'] ); else if ( !empty($_ENV['TEMP']) ) return realpath( $_ENV['TEMP'] ); // Detect by creating a temporary file else { // Try to use system's temporary directory // as random name shouldn't exist $temp_file = tempnam( md5(uniqid(rand(), TRUE)), '' ); if ($temp_file) { $d_temp = realpath( dirname($temp_file) ); unlink( $temp_file ); return $d_temp; } else return FALSE; } } } $d_temp= sys_get_temp_dir(); if ($d_temp===false) die('Cannot retrieve temporary path'); $d_temp = str_replace('\\','/', $d_temp); if ($d_temp[strlen($d_temp)-1]!='/') $d_temp .= '/'; // now $d_temp contains a correctly formatted path e.g. C:/Windows/TEMP/ $my_temp_subdir = $d_temp.'39198_exists'; if (@rmdir($my_temp_subdir)) echo "I just removed a previous <strong>$my_temp_subdir</strong> folder, now "; // create a directory under the temporary path if (!mkdir($my_temp_subdir)) die("I could not create <strong>$my_temp_subdir</strong>"); else echo "<strong>$my_temp_subdir</strong> was created "; // use here temp_is_dir() to see how the script should work instead $b = is_dir($my_temp_subdir); if (!$b) echo "but the folder is not a dir (through is_dir())!"; else echo "and is recognized as a dir (through is_dir())"; // workaround function function temp_is_dir($dir) { // check directory existance under temp folder (tested on Windows) // see bug #31918 http://bugs.php.net/bug.php?id=39198 // by legolas558 if (!@mkdir($dir)) return true; rmdir($dir); return false; } ?> I get this talkative output: [code] C:/WINDOWS/Temp/39198_exists was created but the folder is not a dir (through is_dir())! [/code] But the correct talkative output would be instead: [code] C:/WINDOWS/Temp/39198_exists was created and is recognized as a dir (through is_dir()) [/code] Note that using the workaround function "temp_is_dir()" in place of "is_dir()" the correct output would be returned instead. Please ask me more if necessary.

Surely you can. Just create all the required directories in the script itself, don't left us guessing which directories exist and which don't. ------------------------------------------------------------------------ [2006-11-09 09:58:45] php dot spam at frogblender dot net I don't have your directory structure either so I can't adapt the script for your machine. The Temp directory will be there in a standard installation of Windows. You then search and replace in my script to adapt to your environment. Finally you create one directory RP_Compile and give Everyone full rights on that directory. It shouldn't take more than five minutes for anyone who knows how to log in to Windows. ------------------------------------------------------------------------ [2006-11-08 21:21:32] tony2001@php.net This script is no enough, as we don't have your directory structure. ------------------------------------------------------------------------ [2006-11-03 19:58:57] php dot spam at frogblender dot net You've already got the reproducing script in my original post. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
