Uploaded images are now saved even if the rest of the form
has errors.
If errors are found in the form then a message is printed up
the top to make it clearer that they need to fix something.
pluggable modules in the 'auth' directory.
Everything is done through authentication_user_login in lib/moodlelib.php
As well as the old default "email" confirmation, I added a new type of
confirmation "none", which basically does no confirmation at all.
servers that have register_globals turned off (this is the
default setting on newer version of PHP).
In fact it's partly a hack that globalises all GET, POST, FILES
AND COOKIE variables. Unfortunately though the SESSION and
USER global session variables are only available as $_SESSION["USER"]
and $_SESSION["SESSION"], which is cumbersome to use.
So, for every request I now make a copy of these two session variables
into $USER and $SESSION. Whenever I update them thoughout Moodle I
now have to call save_session("USER") which copies them back to the
session variable. This seems to be working well now.
Because I'm using $_SESSION etc now this will raise
the required minimum version of PHP to 4.1.0
rely on the administrator to tell us which is installed because PHP
is not reliable (eg GD 2.* functions are available in 4.0.6 and later
EVEN WHEN gd 2 is not present ... sigh).
So, new config variable $CFG->gdversion
