#35233 [NEW]: session_name gives bad result with session.auto_start=true

From: gandalf at flock dot com Operating system: All PHP version: 5.0.5 PHP Bug Type: Session related Bug description: session_name gives bad result with session.auto_start=true Description: ------------ As mentioned in bugs 1988 and 16389 when you set up session.auto_start=true, then you can't play with session_name. It's ok. But if so, then session_name() should return the REAL name, not the false one. It's totally misleading to accept session name change (without an Exception). Reproduce code: --------------- 1) Set session.auto_start=true in php.ini 2) <?php session_name('foo'); session_start(); print('Session name: '.session_name()); ?> Expected result: ---------------- Session name: PHPSESSID Actual result: -------------- Session name: foo 'session_name()' should give the real session cookie name. -- Edit bug report at http://bugs.php.net/?id=35233&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=35233&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=35233&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=35233&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=35233&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35233&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35233&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35233&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35233&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35233&r=support Expected behavior: http://bugs.php.net/fix.php?id=35233&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35233&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35233&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35233&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35233&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35233&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35233&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35233&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35233&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35233&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35233&r=mysqlcfg
