Hello

I am building a web application based on CGI::Application. Also using Plugin::Session to keep session state. In one run mode of the application users are allow to upload a file. I am also saving session state in my post run using:

sub cgiapp_postrun {
    my $self = shift;
    #die Dumper($self);
       $self->session->save_param();
       $self->session->flush();
}

my session Driver is file and I believe therefor uses Data::Dumper. Anytime I try to either Dump the session data using Dumper() or hit the pst run I get the following error:

Assertion ((buffer)->sv_flags & 0x00000400) failed: file "sv.c", line 
+1741 at /usr/lib/perl5/5.10.0/i386-linux-thread-multi/Data/Dumper.pm 
+line 190

Also if I die $q->param('bulk_upload'); the field is not populated. bulk_upload is the name of my upload field.

Has anyone seen this? I found this http://www.nntp.perl.org/group/perl.perl5.porters/2009/05/msg146341.html but don't know enough to know if this is the same issue.

Thanks in advance,

Cory

UPDATE:

perl 5.10.1 installed, getting same error, but found this post

Talks about deleting the FH pointer in the session, I have both 

 $self->session->clear(['bulk_upload']);and $q->param('bulk_upload',''
+);
$self->session->clear('bulk_upload');

funny thing is it gets past this the first time, and if I clear the CGI session file, 

 
_SESSION_REMOTE_ADDR' => '10.10.192.63','bulk_file' => bless( \*{'Fh::
+fh000018yy_import.txt'}, 'Fh' ),'_SESSION_CTIME' => 1261427840,'bntsu
+bmit' => 'Upload File','_SESSION_ATIME' => 1261427915,'bulk_upload' =
+> '','authen_loginbutton' => 'Sign In','Agree' => 'Agree','_SESSION_E
+XPIRE_LIST' => {}};;$D[rootvi /var/www/chkdwn/cgi-bin/Sup*/Index.pm

After that I get the following Do not know how to reconstitute blessed object of base type GLOB

UPDATE: PROBLEM SOLVED

on the advice from ikegami and others, of not including the CGI upload FH in the session data. I realized that the CGI param had to be copied to a variable and removed from the CGI param list before the CGI::Session config

Here is what the I had to do in the CGI::Application setup stage. 

my $q = $self->query();
$upload_file = $q->param('bulk_file');
$q->param('bulk_file','');
$self->session_config(...

Thanks again to all that helped
