pnotes and notes not working from Apache::Registry to handler
Hi,
I'm trying to store data about a user who has authenticated in
$r->pnotes so that a perl logging phase handler can stick the user_id in
the db. I call $r->pnotes('keyname' => 'somevalue'); in an apache
registry script, and then call $r->pnotes('keyname') in the logging
handler later on during the logging phase, but am getting nothing back.
No errors, just undef. I've tried notes too, and no luck their either.
I'm using Apache::Request btw. I've also tried retreiving a tied hash
using $r->pnotes() and there are no key/values in that either.
Is it possible to use pnotes to pass data from an Apache::Registry
script to a handler? Perhaps thats the prob - didn't find anything that
said otherwise.
Did I forget to compile apache or mod_perl with an option of some sort?
I can't think of any other explanation. I compiled mod_perl with
EVERYTHING=1
Thanks,
Mark.

Found this piece of info in the archives. I'm also running 1.27. Is this
a known bug?
http://groups.yahoo.com/group/modperl/message/45472
*snip*
Subject: notes/pnotes broke between 1.25=>1.27
So I got the advisory about the Apache servers having a security hole,
so I
decided to upgrade some servers. I've been on v1.25 for awhile, so
decided
to upgrade to 1.27 while I was at it... big mistake.
NONE of my notes/pnotes were getting thru, on the new version.

thanks. :)
I've ploughed through the manual and I'm pretty sure I've been trying
both notes and pnotes correctly. There's also a fairly common mistake of
assuming you're dealing with the initial request, when in fact
Apache->request is a sub-request and you need to use $r->main to
retrieve the main request to access your pnotes. I'm not making that
mistake either.
The last option you mention about mod_perl compilation options: I've
compiled with EVERYTHING=1 and I even grep'd the apache and mod_perl
source just now for 'pnotes' to see if I could spot anything. Nothing
popped out at me.
I'll try to recompile with
PLUS_THAT_OTHER_LITTLE_THING_NOT_INCLUDED_IN_EVERYTHING=1 now and see if
I have better luck ;)

the mod_perl API book specifically said pnotes is the way to communicate
between handlers. As I have hte PDF version, I can't exactly cut & paste it
easily...
pnotes gets cleared after every request, so good thinking on trying notes, as
it apearently doesn't.
the basic usage is this:
$r->pnotes("MY_HANDLER" => [qw(one two)]);
my $val = $r->pnotes("MY_HANDLER");
print $val->[0]; # prints "one"
So basically, $r->pnotes("MY_HANDLER" => [qw(one two)]); will create a hash
where MY_HANDLER is a key to an anonymous array.
my $val = $r->pnotes("MY_HANDLER"); sets $val to be the reference to that
array.
print $val->[0]; dereferences the first spot in the array reference. The
dereferencing thing is key here. $val[0] will throw errors about globals not
being declared as arrays or something of that sort.

There is the problem right there. It needs to be compiled with "EVERYTHING=1
PLUS_THAT_OTHER_LITTLE_THING_NOT_INCLUDED_IN_EVERYTHING=1".
:P
