#45406 [NEW]: Session.serialize_handler declared by shared extension in php.ini don't work

From: oleg dot grenrus at dynamoid dot com Operating system: PHP version: 5.2.6 PHP Bug Type: Session related Bug description: Session.serialize_handler declared by shared extension in php.ini don't work Description: ------------ PHP warnings are issued as PHP Warning: session_start(): Unknown session.serialize_handler. Failed todecode session object. in - on line 2 PHP Warning: Unknown: Unknown session.serialize_handler. Failed to encode session object. in Unknown on line 0 These happen because session module try's to find serialize_handler before serializer module is loaded (and registered itself as valid serialize_handler) There are check for save_handler (PS(mod) != NULL) in the PHP_RINIT_FUNCTION(session), but not for PS(serializer) I wrote a short patch http://phadej.daug.net/php-5.2.6-serialize_handler.patch against php-5.2.6. PHP_RINIT_FUNCTION seems to be same in php-5.2 and php-5.3 brances. Reproduce code: --------------- php -d "extension=wddx.so" -d 'session.serialize_handler=wddx' <<\EOF <?php var_dump(session_start()); ?> EOF Expected result: ---------------- bool(true) Actual result: -------------- PHP Warning: session_start(): Unknown session.serialize_handler. Failed to decode session object. in /home/phadej/dev/php-sess-bug/- on line 2 bool(true) PHP Warning: Unknown: Unknown session.serialize_handler.
