Authorization question and subdirectories
Is it possible to have the same PerlAuthzHandler use different require's on a subdirectory once a user has been authorized for a parent directory? Here is what i would like to be acle to do: SetHandler perl-script AuthType MyAuth AuthName MyAuth PerlAuthenHandler MyAuth->authenticate PerlAuthzHandler MyAuth->authorize require valid-user SetHandler perl-script AuthType MyAuth AuthName MyAuthSupertight PerlAuthenHandler MyAuth->authenticate PerlAuthzHandler MyAuth->authorize require user administrator authenticate is working fine and when I debug the $r->requires in authorize it only returns the 'valid user' requirement and not the "user administrator" requirement even when i access /restricted. Right now the code in authorize just prints the requirements via $r->log_error() then returns OK; What am I missing? Why doesn't authorize see the second requirement for the URI /restricted?
Pnotes not working
I am having trouble getting pnotes to work and wonder if there is
something obvious I am missing. in PerlAuthenHandler I have gone back
to the Apache man page and tried to recreate the example given there but
to no avail. Below is the code:
package My::User;
sub handler{
my $r = new Apache::Request(shift);
$r->log_error("Are we actually here?");
$r->pnotes("MY_HANDLER" => [qw(one two three)]);
}
# seperate file
package My::Main;
sub handler{
my $r = new Apache::Request(shift);
my $var = $r->pnotes("MY_HANDLER");
$r->log_error("This is var $var->[0]");
}
in httpd.conf
SetHandler perl-script
AuthType test
AuthName test
PerlAuthenHandler My::User
require valid-user
PerlHandler My::Main
when I check the error log it is hitting the My::User::handler but
nothing is returned to $var in My::Main. if i just check $r->pnotes()
it returns an empty hash ref.
On another note i originally had My::User::handler named
My::User::authenticate but when called from httpd.conf I got an error
"Could not locate object method authenticate via package My::User."
even though I did preload both My::Main and My::User in startup.pl and
also added a PerlModule My::User to httpd.conf just to be sure. perhaps
the two are related but I cannopt figure out either for the life of me.
any help would be greatly appreciated.

Re: access log and the request object
How about writing your own log handler
PerlLogHandler My::LogModule
or in your code
$r->push_handler(PerlLogHandler => \&MyLoghandler);
sub MyLoghandler{
my $r=Apache::Request;
code to log info to file
}
the push_handler method does not pass the request object to the subroutine.

Hi, I

it be possible to modify the request object so that the url that gets logged

example, if a client requested /file which was redirected to this module
could it modify either the request object or some apache internal so that
it gets written in the access log as /file?session=1234567890abcdef

Storable question (More info)
Sorry, I am running mod_perl 1.24_01, Apache 1.3.19, on Redhat 7.0 Storable 1.011
Storable (lock_store lock_retrieve) question
I am currently using Storables lock_store and lock_retrieve to maintain
a persistent data structure. I use a session_id as a key and each data
structure has a last modified time that I use to expire it. I was under
the impression that these two functions would be safe for concurrent
access, but I seem to be getting 'bad hashes' returned after there is an
attempt at concurrent access to the storable file. Any pointers would
be appreciated. Below is a simplified example of what I am doing.
my $hr=lock_retrieve("my_file");
for(keys %{$hr}){
delete $hr->{$_} if ($hr->{$_}->{time} < time- $session_length)
}
# do stuff here
$hr->{sid}->{other_stuff}=$whatever;
# restore file
lock_store($hr,"my_file");
P.S. Thanks to all who contribute regularly on this list. I find it

Re: push_handlers question
Thanks all. My real question was not so much HOW to fix but more WHY do
i need to fix. I did not realize that using push_handlers would not
send the Apache request to the method handler.

Re: push_handlers question
Thanks for the suggestion, but what i really want to know is why is the request object passed if I call the module directly from http.conf and not when I use the push handlers method? Are the two methods not functionally equivalent? Everything works fine when the handler is set in httpd.conf.

push_handlers question
I am trying to sub class Apache::AuthCookieURL and would like to use $r->push_handlers(PerlAuthenHandler => My::Class->authenticate); the push_handler is set in a handler called from httpd.conf on the PerlInitHandler phase but the authenticate routine does not seem to be getting the apache request object passed to it as I get a can't call dir_config on an udefined value error. I'm sure I am missing something simple but can someone point it out to me. Thanks
