I have a public page which allows users to sign up for their
own sitegroup. My basic algorithm looks like this... (not exact code)
------------------------
mgd_auth_midgard( ROOT, ROOT_PASS, 0);
$sg = mgd_create_sitegroup( $newsitename);
mgd_unsetuid();
mgd_auth_midgard( ROOT."!".$newsitename, ROOT_PASS, 0);
$ag = mgd_create_group( $newsitename." admins", ...);
$ug = mgd_create_group( $newsitename." users", ...);
mgd_unsetuid();
mgd_auth_midgard( ROOT, ROOT_PASS, 0);
$rc = mgd_update_sitegroup( $sg, $newsitename, $ag, "");
-------------------------------
So, I notice a couple of things...
1. The final mgd_auth_midgard _SOMETIMES_ fails mysteriously, for no good reason.
Printing mgd_errstr() shows something like "Object does not exist". As a result the
mgd_update_sitegroup also fails.
2. I notice that doing: unset( $midgard);
After the mgd_unsetuid() seems to help. Can anyone explain why?
3. Documentation on midgard functions seems to be out of date:
- mgd_update_sitegroup seems to take 4 args, not 3.
4. Could someone elaborate on the $midgard global var? Is it always advised to set it
after doing a mgd_auth_midgard???? E.g.
$midgard = mgd_get_midgard();
5. I've also noticed that when switching sitegroups, PHP variables get clobbered. E.g.
mgd_auth_midgard( ROOT."!sitethree". ROOT_ADMIN, 0);
$art = mgd_get_article( 12);
mgd_auth_midgard( ROOT."!sitefive". ROOT_ADMIN, 0);
sometimes even causes apache to segfault!
TIA for any insight into these subjects...
