Still relevant in 7.2.1 too. TIA, Matteo Previous Comments: ------------------------------------------------------------------------ [2017-12-05 08:48:07] damyon at moodle dot com Sorry the test script has "S>" lines in it (copy / paste problem). ------------------------------------------------------------------------ [2017-12-05 08:38:34] damyon at moodle dot com Description: ------------ When unit testing session-related code in a CLI environment, appropriate PHP ini settings combined with passing false to session_cache_limiter should allow the session handler to be changed even if output has been already sent. With PHP 7.2.0RC5 calling session_set_save_handler prints warning messages, regardless of php ini settings.
