Req #73202 [NEW]: Pass origin (callee) as second parameter to autoloading implementations

From: philippwrann at gmail dot com Operating system: all PHP version: Next Major Version Package: SPL related Bug Type: Feature/Change Request Bug description:Pass origin (callee) as second parameter to autoloading implementations Description: ------------ At the moment it is not possible to implement dependency managers that can handle different versions of the same package. If the callee (file location) would be provided as second parameter for autoload callbacks a autoloading implementation could determine the correct version to load. Some real world example: You start a new composer based project and require some third party package. That package requires another package, for example some api. So long all is good Now you require one more package, that requires the same package but in another version => not possible. A fix would be downwards compatible because the additional parameter would simply be ignored by current implementations. Test script: --------------- // something like this spl_autoload_register(function($className, $originPath){ get_real_autoloader($originPath)->load($className); }); -- Edit bug report at https://bugs.php.net/bug.php?id=73202&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73202&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73202&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73202&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73202&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73202&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73202&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73202&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73202&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73202&r=support Expected behavior: https://bugs.php.net/fix.php?id=73202&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73202&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73202&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73202&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73202&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73202&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73202&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73202&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73202&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73202&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73202&r=mysqlcfg
