#48493 [NEW]: spl_autoload_unregister() removes all autoloaded methods when prepending

From: craig dot marvelley at boxuk dot com Operating system: Windows XP PHP version: 5.3.0RC2 PHP Bug Type: SPL related Bug description: spl_autoload_unregister() removes all autoloaded methods when prepending Description: ------------ The spl_autoload_register function was recently modified (I don't think it's documented, though) to allow the pre-pending of functions to the stack (see bug #42823). I'm using pre-pending and am later trying to remove a registered function from the end of the stack. This removes ALL methods, not just the method I'd intended. Reproduce code: --------------- function autoload1() {} function autoload2() {} spl_autoload_register('autoload2'); // register autoload1 at the bottom of the stack spl_autoload_register('autoload1', true, true); // Output: Array ( [0] => autoload1 [1] => autoload2 ) print_r(spl_autoload_functions()); // unregister autoload2 - autoload1 _should_ be left behind spl_autoload_unregister('autoload2'); Expected result: ---------------- When running spl_autoload_functions(), I'd expect a single entry to be left: array([0] => 'autoload1'); Actual result: -------------- The array is empty: array(); -- Edit bug report at http://bugs.php.net/?id=48493&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48493&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48493&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48493&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48493&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48493&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48493&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48493&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48493&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48493&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48493&r=support Expected behavior: http://bugs.php.net/fix.php?id=48493&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48493&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48493&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48493&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48493&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48493&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48493&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48493&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48493&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48493&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48493&r=mysqlcfg
