[Catalyst] about catalyst authentication

Because you're using Session::Store::FastMmap and the session cache file
didn't exist before your app started, so Cache::FastMmap deletes it on exit?

Andrew

Thanks. I think so, too. But why Cache::FastMmap deletes it? Where can set
it?

I just use all config default.

use Catalyst qw/-Debug
ConfigLoader::MultiState
Static::Simple

StackTrace
Authentication

Session
Session::Store::FastMmap
Session::State::Cookie/;

Plugin-Authentication.conf:

$default_realm = 'default';
$realms = {
'default' => {
'credential' => {
'class' => 'Password',
'password_field' => 'password',
'password_type' => 'hashed',
'password_hash_type' => 'MD5',
},
'store' => {
'class' => 'DBI',
'user_table' => 'qy_user',
'user_key' => 'id',
'user_name' => 'username',
'user_password' => 'password',
},
},
};

$use_session = 1;

Hi Andrew

debian:/tmp/qy# ls
session_data

The point is, your sessions are going to be cleared out upon server restart.

Yep. but how to fix this problem?

If your data needs to be more persistent save it in the database

I think something is wrong. Please check:

I have two apps wc and qy:

* WC:*

debian:/tmp/wc# /etc/init.d/apache2 start
Starting web server: apache2.
debian:/tmp/wc# ls
session_data
debian:/tmp/wc# /etc/init.d/apache2 stop
Stopping web server: apache2 ... waiting .
debian:/tmp/wc# ls
session_data

*The session_data is there and user needn't login again.*

Read the docs.

http://search.cpan.org/~robm/Cache-FastMmap-1.28/FastMmap.pm

If the share_file exists when the process starts it won't be deleted on
exit. If it doesn't exist the default is to delete it when the process
exits.

If you want to be sure of it existing pass undelete_on_exit => 0 to the
constructor.

S.

Thanks all.

It's ok now.

I find:

debian:/tmp/qy# ls
session_data
debian:/tmp/qy# /etc/init.d/apache2 stop
Stopping web server: apache2 ... waiting .
debian:/tmp/qy# ls
debian:/tmp/qy#

The session file is cleared out when apache stop.

How to fix this problem?

probably because the session is cleared out
