Re: $r->requires and register_auth_provider

[A. Warnier]

Hi Sergei.
My turn to thank you for providing the information below (and also to Michael Schout of 
course). That will also be invaluable to me, when I get around to update my own mod_perl 
AAA modules.

Yep, I can see what I should do now. For the benefit of others here are the 
differences:

OLD STYLE
=========

<Location blah>
     PerlAuthzHandler YOUR_MODULE->YOUR_METHOD
     require user fred
     require group fred
</Location>```


Then in your YOUR_METHOD you would do something like:

my $requires = $r->requires
process your requires ..


​NEW STYLE:
​==========​

PerlAddAuthzProvider user YOUR_MODULE->YOUR_USER_AUTHZ_METHOD
PerlAddAuthzProvider group YOUR_MODULE->YOUR_GROUP_AUTHZ_METHOD

<Location blah>
    require user fred
    required group fred
</Location>```


And in your YOUR_MODULE:

sub YOUR_USER_AUTHZ_METHOD {
    my ($self, $r, @requires) = @_;
}

sub YOUR_GROUP_AUTHZ_METHOD {
    my ($self, $r, @requires) = @_;
}

Thanks, André for helping me finally solve this problem. From your link on
Apache-AuthCookie, I also found this:
​ ​
http://search.cpan.org/~mschout/Apache-AuthCookie-3.23/README.apache-2.4.pod 
and in there
I read under APACHE 2.4 PORTING NOTES.


​Thanks again,​

    Hi.

    I don't have anything very precise to tell you, but here is what I know :
    The AAA part has been significantly changed in Apache httpd 2.4, as 
compared to 2.2.
    Therefore I suspect - but I am not sure - that some corresponding changes 
had to be
    made in mod_perl, to adapt to these changes.
    One of the changes that I see when looking at the Apache 2.4 vs 2.2 on-line
    documentation (for Apache, not for mod_perl), concerns the syntax - and who 
handles -
    the "Require" directives.

    I also believe that the on-line mod_perl documentation does not yet reflect 
these
    changes, and it seems a bit hard to find an up-to-date documentation yet.

    But anyway, I just found this on CPAN :
    
https://metacpan.org/source/MSCHOUT/Apache-AuthCookie-3.23/lib/Apache2_4/AuthCookie.pm

    That - along with the module name - seems to show a way to obtain the 
"Require" that
    you need.  Why don't you give it a try ?

    Another way that I can think of, would be to use the Apache2::Directive 
module
    (http://perl.apache.org/docs/2.0/api/Apache2/Directive.html), to obtain the 
Require
    via the server's configuration tree.
    That should be independent of the specific Apache version being used.

        Hello,

        I’m using mod_perl-2.0.8-10 and I’ve been googling for days for this 
info w/o any
        luck.

        I need to access the value for the Require directive in the apache 
configs. I need
        to access that info in my authorization handler (PerlAuthzHandler). It 
used to be
        that $r->requires provided that information, but it’s gone now 
according to the
        changelog. It has been replaced with register_auth_provider and 
according to this:

        perl -MModPerl::MethodLookup -e print_method register_auth_provider
        To use method 'register_auth_provider' add:
                  use Apache2::RequestUtil ();

        … it should be in Apache2::RequestUtil. But I can’t find anything about 
that
        method in the description of Apache2::RequestUtil. Further, I get 
“undefined
        method” when I try to even mention it in my handler.

        I must be missing something really simple? Can somebody point me to a 
full example
        of using that method?

        Thanks!
