Hi Cristiano,

According to the PHP manual, http://php.net/manual/en/function.session-
id.php

"Depending on the session handler, not all characters are allowed within
the session id. For example, the file session handler only allows
characters in the range a-z A-Z 0-9 , (comma) and - (minus)!"

So it sounds like we should allow more characters for the session paths.

Looking at
http://php.net/manual/en/session.configuration.php#ini.session.sid-
length it seems that a few new options were introduced in PHP 7.1

Currently our session bits_per_character is set to handle the option '4'

We will need to expand this so it handles option '5', and '6' as well

Cheers

Robert

Title:
  Sessions directories missing after upgrade to 16.10 and php 7.1 on
  Ubuntu 16.04 LTS

Status in Mahara:
  In Progress

Bug description:
  Hello,

  I updated my mahara installation to 16.10. At the same time I did an
  upgrade to from Ubuntu 14.04 to 16.04 and to php 7.1.

  Suddenly users where not able to login, I checked the error log and I
  found this:

  2017/03/07 11:01:35 [error] 19414#19414: *100640 FastCGI sent in
  stderr: "PHP message: [WAR] 72 (auth/session.php:457)
  session_regenerate_id():
  open(/data/maharadata/sessions/8/e/h/sess_8ehlbf3hbll0tjjiatl25d69i7,
  O_RDWR) failed: No such file or directory (2)

  I checked the session store structure and just directories between 0
  and f where there. I had to create the whole structure with all
  subdirectories from 0 to z.

  I don't know if the session format comes form php 7.1 or from mahara,
  anyway the folder structure should be created accordingly to
  accomodate this format.
