Bug #53036 [NEW]: class_exists fails to return for missing dependent classes

From: Operating system: FreeBSD 8.1-RELEASE PHP version: 5.2.14 Package: Class/Object related Bug Type: Bug Bug description:class_exists fails to return for missing dependent classes Description: ------------ If you call class_exists( $sClass ) which in turn triggers an autoloader that fails to load a dependent class of $sClass e.g. where $sClass extends a missing class, then class_exists fails silently and never returns. Note this only fails on missing dependent classes if the original class fails to load then class_exists returns false as expected. Also tested on 5.3.3 same results Test script: --------------- Test case files here: http://www.multiplaygameservers.com/dropzone/php-autoload-failure.tar.gz Expected result: ---------------- factory: MyClass autoload: MyClass including: MyClass autoload: MyBaseClass including: MyBaseClass included: for MyBaseClass, Failed to autoload: MyClass Failed to load 'MyClass' Actual result: -------------- factory: MyClass autoload: MyClass including: MyClass autoload: MyBaseClass including: MyBaseClass included: for MyBaseClass, <-- Nothing more --> Running with missing initial class: factory: MyClass autoload: MyClass including: MyClass included: for MyClass, Failed to autoload: MyClass Failed to load 'MyClass' -- Edit bug report at http://bugs.php.net/bug.php?id=53036&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53036&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53036&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53036&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53036&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53036&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53036&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53036&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53036&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53036&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53036&r=support Expected behavior: http://bugs.php.net/fix.php?id=53036&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53036&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53036&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53036&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53036&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53036&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53036&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53036&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53036&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53036&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53036&r=mysqlcfg
