Here's some more information. I added debug output to
sqsession_register and sqsession_unregister
register gettext_php_loaded
unregister gettext_php_loaded
error unsetting _SESSION gettext_php_loaded
Notice: Undefined variable: _SESSION in /mnt/www/squirrelmail-1.2.10/src/global.php on
line 113
register gettext_php_domain
unregister gettext_php_domain
register gettext_php_dir
unregister gettext_php_dir
register gettext_php_translateStrings
unregister gettext_php_translateStrings
register gettext_php_loaded_language
unregister gettext_php_loaded_language
register gettext_php_short_circuit
unregister gettext_php_short_circuit
which is being called from gettext.php via i18n.php
It looks like $_SESSION isn't a defined global variable. How is that
possible? Well I had a look around and it doesn't look like
session_start(); is being called anywhere from the login page before
the require_once('../functions/i18n.php');
Adding session_start() before that require got rid of the warning.
However I do not think this is a good patch, and suspect there are many
other places missing a session_start
Another fix I just thought of, is to change session.auto_start = 1
in php.ini. The default was off. This also seems to eliminate the
warning, but I'm not sure what other consequences it might have
(probably slowing down the vast majority of php scripts I have which do
not use sessions)
Anyway, seems to be a serious bug.
Thanks
