Bug #75047 [NEW]: session_regenerate_id fails with redis

From: bartosz at kibilko dot pl Operating system: Ubuntu / Docker Container PHP version: 7.0.22 Package: Unknown/Other Function Bug Type: Bug Bug description:session_regenerate_id fails with redis Description: ------------ PHP 7.0.21 phpredis 3.1.2 redis 3.0.7 / 3.2.4 Magento 1.14.2.4 Context: There are some problems with session_regenerate_id function when redis is used as session adapter. Currently, I'm trying to login in Magento and session_id is stored in redis and in cookies but nothing happens - user is not logged in. When I remove the cookie, PHP throws this: Recoverable Error: session_regenerate_id(): Failed to create(read) session ID: redis (path: tcp://redis:6379/?database=2). It can be also related to phpredis, because version 3.1.3 has another bug :) - https://github.com/phpredis/phpredis/issues/1211 Expected result: ---------------- No errors, user logged in Actual result: -------------- Recoverable Error: session_regenerate_id(): Failed to create(read) session ID: redis (path: tcp://redis:6379/?database=2) in /var/www/mage/magento/app/code/core/Mage/Core/Model/Session/Abstract/Varien.php on line 141 #0 [internal function]: mageCoreErrorHandler(4096, 'session_regener...', '/var/www/magent...', 141, Array) #1 /var/www/mage/magento/app/code/core/Mage/Core/Model/Session/Abstract/Varien.php(141): session_regenerate_id(false) #2 /var/www/mage/magento/app/code/core/Mage/Core/Model/Session/Abstract/Varien.php(222): Mage_Core_Model_Session_Abstract_Varien->start('frontend') #3 /var/www/mage/magento/app/code/core/Mage/Core/Model/Session/Abstract.php(84): Mage_Core_Model_Session_Abstract_Varien->init('core', 'frontend') #4 /var/www/mage/magento/app/code/core/Mage/Core/Model/Session.php(42): Mage_Core_Model_Session_Abstract->init('core', 'frontend') #5 /var/www/mage/magento/app/code/core/Mage/Core/Model/Config.php(1354): Mage_Core_Model_Session->__construct(Array) #6 /var/www/mage/magento/app/Mage.php(471): Mage_Core_Model_Config->getModelInstance('core/session', Array) #7 ......... -- Edit bug report at https://bugs.php.net/bug.php?id=75047&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75047&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75047&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75047&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75047&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75047&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75047&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75047&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75047&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75047&r=support Expected behavior: https://bugs.php.net/fix.php?id=75047&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75047&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75047&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75047&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75047&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75047&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75047&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75047&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75047&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75047&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75047&r=mysqlcfg
