Apache2::Cookie odd return values

[John ORourke <jo...@o-rourke.org>]

(mp 2.0.1, libapreq2-2.06-dev, httpd 2.0.51, Fedora Core 2)

Hi folks,

I've spent 2 days trying simply to read and write cookies!  Just before 
I pack it in and become a paper boy, can anyone help?

If you haven't time to read below but have some working cookie 
read/write freeze/thaw code or URLs I'd be grateful!

It seems I can bake cookies no problem, they're appearing in the browser:

$c_out_val=Apache2::Cookie->freeze($my_hash_ref);
Apache2::Cookie->new( blah blah )->bake();

But I just can't unfreeze them!  I've tried the following ways to get my 
cookies:

$jar=Apache2::Cookie::Jar->new($r)
$jar=Apache2::Cookie->fetch($r)
(I also tried using APR::Request::Cookie but it seems to be for Apache 
experts only, quite a confusing interface)

...but the cookie value is always "cookie_name=cookie_value", and with 
some variations I was getting a second cookie, with a blank value and 
the name was "cookie_name=cookie_value".

Anyway, even when I strip the "cookie_name=" off the cookie value,  
Apache2::Cookie->thaw($value) just returns $value!

Any help gratefully accepted,

John O'Rourke

Likely this change in the API caught you (2.05-dev and up)

Perl API [joes]
   Move bake, bake2 to Apache2::Cookie, now requiring
   an extra $r argument.  Also ""-operator is mapped
   to as_string() for Apache2::Cookie;  but APR::Request::Cookie
   maps it to value().

AND/OR

(2.06-dev and up)
Perl API [joes]
Drop support for Apache2::Cookie::Jar::new's VALUE_CLASS. 2.05-dev broke 
that API, and it's not worth trying to fix. People who need that should 
use APR::Request::Cookie::Table's cookie_class() API instead.

Strangely enough, everything you talk about here is by design.
And it's also why we recommend the new APR::Request:: modules
over Apache2::Cookie and friends, because it's IMO a simpler API.

Right, I've solved my problem with a hack and some RTFSing, but I think 
I've found a bug either in the docs or Apache2::Cookie...

Basically if I read cookies like this:
$cookie_hash_ref = APR::Request::Apache2->handle($r)->jar();
it works, I can treat the return as a hash of cookies.

However, if I (following the Apache2::Cookie man page) go:
$jar=Apache2::Cookie->new($r);
foreach $name ($jar->cookies()){ blah blah }
then the names are actually the full baked header value (eg. "name=value")

I have to crack on with my project but I'll leave that one with you.  
Phil, thanks for the pointers and the cookie recipes in the FAQ!

Lets move this to apreq-dev (at) httpd.apache.org

Not an issue, but httpd 2.0.54 is out since you're using the rest current :)

I don't know about freeze/thaw, but I wrote this FAQ :)

HA, I know you're not calling me an apache expert :)
