PHP7 site/login session_regenerate_id

[githubjeka]

Related to #1812

I spent two days to get to this error

session_regenerate_id(): Failed to create(read) session ID: user (path: )

on PHP7RC8 site/login & site/logout just return 500 Error . There are no messages in any log.

All because of this @. https://github.com/yiisoft/yii2/blob/master/framework/web/Session.php#L260

I'm very indignant

P.S. https://bugs.php.net/bug.php?id=70520

i met the same problem on mac osx with php7RC5. I use yii2 framework with redis as session storage.It is ok when i install php7RC2, but get error session_regenerate_id(): Failed to create session ID: user (path: ). Is this issue fixed after RC3?

UPD: updated to php 7.0.0 . Same error.

UPD2:

I commented the code

    'components' => [       
        //'session' => [
        //    'class' => 'yii\redis\Session',
        //    'timeout' => 60 * 60 * 24 * 30,
        //],

And now users can login & logout in site.

Problems

1. What is wrong with yii\redis\Session .
2. Too much @ in vendor/yiisoft/yii2/web/Session.php which hinder debugging

Too much @ in vendor/yiisoft/yii2/web/Session.php which hinder debugging

[samdark]

Any idea how to fix that?

[githubjeka]

In this case
Warning: session_regenerate_id(): Session object destruction failed

I also stumbled at this. This related with public function destroySession($id)
http://php.net/manual/ru/function.session-set-save-handler.php

Similar fix is need as PR:

 $data = $this->redis->executeCommand('DEL', [$this->calculateKey($id)]);
 return $data === '' || $data === null ? false : true;

But I have burdened #1812 (comment)

Another @ have no comment and therefore not very clear why hide the display of errors.

[samdark]

@githubjeka I think all these @ are used in alike race condition cases.

[githubjeka]

But It just hide error, not fix in this case:

on PHP7RC8 site/login & site/logout just return 500 Error in browser . There are no messages in any log.

Last thing I thought that Yii2 have @ for understand why 500.

[samdark]

Well, in these cases, it's obviously wrong.
