#37027 [Bgs]: mkdir($dir, 0777, true) does NOT chmod created directory

ID: 37027 User updated by: spambox at gery dot pl -Reported By: mateusz at heleniak dot net +Reported By: spambox at gery dot pl Status: Bogus Bug Type: Documentation problem Operating System: Apache, Unix PHP Version: 5.1.2 New Comment: Email update (because of spam). Previous Comments: ------------------------------------------------------------------------ [2006-04-10 14:15:23] vrana@php.net It is already documented: "The mode is also modified by the current umask, which you can change using umask()." ------------------------------------------------------------------------ [2006-04-09 20:37:58] tony2001@php.net Reclassified as docu problem. mkdir(dir, mode) actualy sets permissions to (mode & ~umask & 0777). So you have to use umask() to 1) unset the correct umask; 2) create the directory with mode 0777; 3) reset umask to it's old value. OR you can use chmod() to change the permissions. See also man 2 mkdir. ------------------------------------------------------------------------ [2006-04-09 20:20:48] spambox at gery dot pl Description: ------------ Directory files/tmp/ has 777 chmod. Script creates files/tmp/tpl-cache/ with 755 chmod! I use recursive because $foo can be 'admin/asf.tpl' too - then there are 2 directory to create. I have seen this bug on PHP Version 5.0.4. It wasn't reported here so probably newest version of PHP has this bug too. PHP5 is installed as CGI or something similar. Please help! I see now this: http://bugs.php.net/bug.php?id=19757 But I can reed on php.net/umask that: "Avoid using this function in multithreaded webservers. It is better to change the file permissions with chmod() after creating the file. Using umask() can lead to unexpected behavior of concurrently running scripts and the webserver itself because they all use the same umask." So.. maybe we can change something to easier using mkdir()? Reproduce code: --------------- define('ROOT', dirname(__FILE__).'/'); $foo = 'asf.tpl'; // sample data $dir = dirname(ROOT.'files/tmp/tpl-cache/'.$foo.'.html'); if(!is_dir($dir) && !mkdir($dir, 0777, true)) { die('Can not create directory structure for cached files.'); } Expected result: ---------------- Directory with 777 chmod. Actual result: -------------- Directory with 755 chmod. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37027&edit=1
