[pmwiki-devel] check authorization requirements for a given page

[Frank Schweickert]

Dear all,

I wanted to find out whether an edit password is set for a given page
and I learned from Hans that PageVar($pagename, '$PasswdEdit'))
should be empty if no edit password is set along the attr cascade.

While that seems to be a sufficient condition for no edit password,
it doesn't seem to be necessarily empty for unprotected pages.
Right now (version 2.2.6)  $PasswdEdit is set to "(protected)"
even for that anyone could edit right away, such as Main, PmWiki groups.
(And I would like to enable the captcha recipe in such cases)

However, I found that PasswdEdit will be empty again as soon as
I access the attr-page by sending my admin password.

So what is a sufficient and necessary condition for
"no edit password set"?

In pmwiki.php I found in function PasswdVar:

 SDV($PasswdVarAuth, 'attr');
 if ($PasswdVarAuth && !@$page['=auth'][$PasswdVarAuth]) return
'(protected)';

But I do not understand what that means.

Best regards,
Frank
