#45328 [NEW]: post_max_size of 6144M of greater causes $_POST to fail

From: corry dot gellatly at ncl dot ac dot uk Operating system: Linux (Fedora Core 8) PHP version: 5.2.6 PHP Bug Type: Session related Bug description: post_max_size of 6144M of greater causes $_POST to fail Description: ------------ Setting post_max_size to a value of 6144M or greater causes $_POST to fail, for example to log in and start a session with the simple code below: <?php session_start(); $username = $_POST['username']; $password = $_POST['password']; ...etc. ?> It will also cause the login to phpMyAdmin to fail with the error message: Warning: Unknown: POST Content-length of 81 bytes exceeds the limit of -2147483648 bytes in Unknown on line 0 At a guess, perhaps to due to the post_max_size variable type? Although 6144M is perhaps an excessive post size maximum, a comment in the php.ini file warning of the maximum limit would be helpful. Reproduce code: --------------- Can be reproduced with the index.php page of phpMyAdmin 2.10.0.2 and above Expected result: ---------------- Failed login when post_max_size >= 6144M -- Edit bug report at http://bugs.php.net/?id=45328&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45328&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45328&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45328&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45328&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45328&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45328&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45328&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45328&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45328&r=support Expected behavior: http://bugs.php.net/fix.php?id=45328&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45328&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45328&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45328&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45328&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45328&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45328&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45328&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45328&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45328&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45328&r=mysqlcfg
