igbinary session support?

[kkretsch]

If I try to enable the current (PHP 7.0.8-1~dotdeb+8.1) php7 runtime my TYPO3 throws this error:

PHP Warning: session_start(): Cannot find serialization handler 'igbinary' - session startup failed in /var/www/typo3_src-7.6.9/typo3/sysext/backend/Classes/Controller/LoginController.php line 93

The igbinary module is installed (cli and fpm configuration both use the igbinary.ini):

php -i|grep igbinary

Additional .ini files parsed => /etc/php/7.0/cli/conf.d/10-igbinary.ini, igbinary igbinary support => enabled igbinary version => 1.2.2-dev igbinary APC serializer ABI => no igbinary session support => no igbinary.compact_strings => On => On session.serialize_handler => igbinary => igbinary

But it doesn't seem to support session handling.

As my TYPO3 site relies on a redis cache I have to enable the php7.0-redis module which in turn uses/needs the php7.0-igbinary module.

Any idea how I can combine those to a running mix?

Currently I still use a self compiled php7 version withour any igbinary which runs OK.

Could you please try to set session.serialize_handler to anything else than igbinary? php_serialize, php, php_binary or wddx (just make sure you installed php7.0-xmlfor this last one), whatever suits your needs.

I tried that switching to php_binary and got:

PHP Warning: igbinary_unserialize_header: unsupported version: 1631203895, should be 1 or 2 in /var/www/typo3_src-7.6.9/typo3/sysext/core/Classes/Cache/Frontend/VariableFrontend.php line 102

as the next error. Even cleaning all redis data didn't help. Or does it read some other source?

Unfortunately, it's an upstream issue. We should both keep an eye on it.

I'll provide new igbinary packages as soon as :

• this upstream issue is fixed
• or if session serialization is finally supported.
