Bug #73835 [NEW]: Redis session handler bug

From: ben at ajmadison dot com Operating system: Centos 7.3 PHP version: 7.1.0 Package: *General Issues Bug Type: Bug Bug description:Redis session handler bug Description: ------------ There is a problem in the redis 3.1 extension in php 7+, when redis is used as a session handler. The problem only manifests itself when new session is being created, and has to do with php7 expecting a String. Please reference a related bug: https://bugs.php.net/bug.php?id=71187 which is for Memcached but Redis seems to have the same issue. The following php workaround fixed the problem: class RedisSession extends SessionHandler { public function read($session_id) { return (string)parent::read($session_id); } } $sess = new RedisSession(); session_set_save_handler($sess, true); Test script: --------------- in php.ini i have: session.save_handler = redis session.save_path = "tcp://localhost:6379?weight=1" in test.php i have: session_start(); Expected result: ---------------- I would expect new session to be initialized. Actual result: -------------- Warning: session_start(): Failed to read session data: redis (path: tcp://local -- Edit bug report at https://bugs.php.net/bug.php?id=73835&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73835&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73835&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73835&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73835&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73835&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73835&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73835&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73835&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73835&r=support Expected behavior: https://bugs.php.net/fix.php?id=73835&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73835&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73835&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73835&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73835&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73835&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73835&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73835&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73835&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73835&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73835&r=mysqlcfg
