Hi all,
This PR disables recursive session save handler function calls (any
multiple/invalid session save handler function calls)
https://github.com/php/php-src/pull/2196
This patch disables many kinds of save handler function abuses and
user script bugs. We have/had many bugs related to this patch,
including number of save handler function related crashes. It also
allows to call session_create_id() in user save handler function.
Currently, SID creation save handler assumes to generate session ID
from scratch. With this patch, users can use session_create_id() to
generate new ID of their own. e.g. User ID prefixed session ID, $newid
= $user_id.session_create_id() in SID creation save handler.
I would like to merge this fix from 7.1, at least required module
global var definition so that it can be fixed later.
