Bug #75737 [NEW]: Opcache has corrupt method signatures after invalidation via files

From: stephan dot lueckl at niceshops dot com Operating system: Debian 8 PHP version: 7.1.12 Package: opcache Bug Type: Bug Bug description:Opcache has corrupt method signatures after invalidation via files Description: ------------ Some examples from the error log (error log is full with this): 1) PHP Fatal error: Uncaught TypeError: Argument 1 passed to ServiceDb_Session::__construct() must be an instance of DB_Generated_ShopWAWIProduct, instance of ServiceDb_Connection given, called in Factory.php on line 25 and defined in Session.php:41 2) PHP Fatal error: Uncaught TypeError: Argument 1 passed to ServiceDb_Session::__construct() must be an instance of Smarty_Internal_Template, instance of ServiceDb_Connection given, called in Factory.php on line 25 and defined in Session.php:41 3) PHP Fatal error: Uncaught TypeError: Argument 1 passed to ServiceDb_Session::__construct() must be an instance of ServiceDb_Connection, instance of ServiceDb_Connection given, called in Factory.php on line 25 and defined in Session.php:41 The session classes are part of an overwritten session handler, that implements the SessionHandlerInterface. You can see - the method signature of the class somehow is corrupted (interesting in example 3: expectation and actual value is equal) This happens after we reinvalidate the opcache via files (reinvalidation script below) - within the reinvalidation this type of session with the overwritten sessionhandler is started. At the moment this problem only occurs within this session classes. As this happens once - all requests to the server are having this error (the overwritten session system is used in every case). Problem can be fixed by calling opcache_reset(); This problem did not occur prior to PHP 7.1.9 Test script: --------------- Method Signature class ServiceDb_Connection { /** * @var ServiceDb_Connection */ private $connection; public function __construct(ServiceDb_Connection $connection) { $this->connection = $connection; } } Opcache Invalidation Script (invalidates the cache from the project base root): $opStatus = opcache_get_status(true); if (is_array($opStatus["scripts"])) { foreach ($opStatus["scripts"] as $file => $info) { if (strpos($file,BASE_ROOT) === 0) { opcache_invalidate($file); } } } -- Edit bug report at https://bugs.php.net/bug.php?id=75737&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75737&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75737&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75737&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75737&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75737&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75737&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75737&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75737&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75737&r=support Expected behavior: https://bugs.php.net/fix.php?id=75737&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75737&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75737&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75737&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75737&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75737&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75737&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75737&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75737&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75737&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75737&r=mysqlcfg
