#44936 [Ctl]: BC break: ini_set() changes 'access' value

ID: 44936 Updated by: stas@php.net Reported By: romain dot dorgueil at sensio dot net Status: Critical Bug Type: *General Issues Operating System: linux 2.6.22-14 PHP Version: 5.2.6 Assigned To: iliaa New Comment: Why it is a problem? As far as I can see, there was a change that now uses some previously unused bits in the access mask, but why it is a bug? Does something that worked before doesn't work now? Previous Comments: ------------------------------------------------------------------------ [2008-05-26 20:31:31] jani@php.net Ilia, I think this is the patch that causes the side-effect: http://cvs.php.net/viewvc.cgi/ZendEngine2/zend_ini.c?r1=1.39.2.2.2.26&r2=1.39.2.2.2.27&pathrev=PHP_5_2 ------------------------------------------------------------------------ [2008-05-07 18:11:18] romain dot dorgueil at sensio dot net Description: ------------ ini_set changes the 'access' parameter of configuration entry to 63 without any reason. This behaviour did not exist in previous versions and is very easy to reproduce. It is not documented and not in the php 5.6.3 changelog. Reproduce code: --------------- <?php define('CONFIG_ENTRY', 'magic_quotes_runtime'); function dumpini() { $configs = ini_get_all(); echo 'access value: '.$configs[CONFIG_ENTRY]['access']."\n"; } dumpini(); echo 'ini_set(\''.CONFIG_ENTRY.'\', 0);'."\n"; ini_set(CONFIG_ENTRY, 0); dumpini(); Expected result: ---------------- access value: 7 ini_set('magic_quotes_runtime', 0); access value: 7 Actual result: -------------- access value: 7 ini_set('magic_quotes_runtime', 0); access value: 63 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44936&edit=1
