Which cache backend you're using?

Which cache backend you're using?

We use Redis.

I see that this issue is going to be resolve. Thanks

There is another problem too - when we use the cache (php8+Yii+Redis), we get this problem
Fatal error: Uncaught CDbException: The table "tablename" for active record class "TablenameRecord" cannot be found in the database. in /srv/www/htdocs/.../framework/db/ar/CActiveRecord.php on line 2391 CDbException: The table "tablename" for active record class "TablenameRecord" cannot be found in the database. in /srv/www/htdocs/.../framework/db/ar/CActiveRecord.php on line 2391
When we cancel the use of the cache, the error disappears. Just comment out these lines in main.conf:
'cache'=>array( 'class'=>'CRedisCache', 'hostname'=> 'localhost', 'port'=>6379, 'database'=>1, ),
The table is existed in DB.

Why it happens and what can we do?

Thank you!

@alexius We recently had a similar case in #4480 with unserialize(null) which turned out to be a problem in application code, not in framework code. Could you provide a bit more thorough reproducible sample code that demonstrates this issue so we can investigate?

There is another problem too (..)

Please create a new issue for this and fill out the required details.

@marcovtwout I did.

@wtommyw confirmed this issue is reproducable with CRedis and the correct fix by #4496

[marcovtwout]

Fixed by #4496
