#46547 [NEW]: PHP doesn't decode cookies anymore when POST body grows large

From: rix0rrr at gmail dot com Operating system: Debian Linux PHP version: 5.2.6 PHP Bug Type: Session related Bug description: PHP doesn't decode cookies anymore when POST body grows large Description: ------------ When the body of a POST request grows too large, PHP stops decoding the passed-in cookies properly. Usually this results in a session that is dropped (the user being logged out, etc.) Reproduce code: --------------- <? session_start(); $FIELDS = 200; ?> PHP Version: <b><?= phpversion() ?></b><br> Cookies: <b><? print_r($_COOKIE);l ?></b><br> Session ID: <b><?= session_id() ?></b><br> <form method="post"> <input type="submit" value="Send"> <? for ($i = 0; $i < $FIELDS; $i++): ?> <input type="text" name="field[$i]" value="<?= md5(microtime()) ?>"> <? endfor ?> </form> Expected result: ---------------- Session id does not change between posts, cookies are displayed. Actual result: -------------- Depending on the setting of $FIELDS, PHP does or does not drop the cookies and therefore the session. On my setup, setting $FIELDS to 100 works fine and the session is maintained, setting $FIELDS to 200 exhibits the behaviour mentioned. -- Edit bug report at http://bugs.php.net/?id=46547&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46547&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46547&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46547&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46547&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46547&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46547&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46547&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46547&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46547&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46547&r=support Expected behavior: http://bugs.php.net/fix.php?id=46547&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46547&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46547&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46547&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46547&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46547&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46547&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46547&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46547&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46547&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46547&r=mysqlcfg
