segfault with perl 5.10 + MasonX::Request::WithApacheSession
[this message elicited no answers so far from mason-users, so maybe the
modperl community might be of help, thanks]
Hi,
Since I've upgraded to perl 5.10 on my debian unstable/sid box I get a
segfault when using MasonX::Request::WithApacheSession:
[Sat May 17 16:14:55 2008] [notice] Apache/2.2.8 (Debian) mod_apreq2-20051231/2.6.0 mod_perl/2.0.4 Perl/v5.10.0 configured -- resuming normal operations
[Sat May 17 16:15:03 2008] [notice] child pid 25786 exit signal Segmentation fault (11)

[Sat May 17 16:15:12 2008] [notice] child pid 25789 exit signal Segmentation fault (11)
etc...
I marked the problematic handler.pl block with comments:
my $ah = new HTML::Mason::ApacheHandler(
autohandler_name=>'ah.mc',
dhandler_name=>'dh.mc',
comp_root=>'/var/www',
data_dir=>'/tmp/mason',
error_mode=>'output',
args_method=>'mod_perl',
## When commented out perl 5.10 works fine
request_class => 'MasonX::Request::WithApacheSession',
session_class => 'Apache::Session::Postgres',
session_data_source => 'dbi:Pg:dbname=sessions',
session_user_name => '',
session_password => '',
session_use_cookie => 1,
session_cookie_expires => undef,
## When commented out perl 5.10 works fine
);
When using a vanilla request_class all is well, but then I have to roll
my own %session object (which is not a huge problem).
I upgraded to libmasonx-request-withapachesession-perl_0.31-1_all.deb
with no difference.
Does someone have an idea about that segfault?
Thanks,

I'm using debian packages which are rebuilt with perl 5.10:
libapache2-request-perl 2.08-5+b1
Depends: perl (>= 5.10.0-9)
libapache2-mod-perl2 2.0.4-1
Depends: perl (>= 5.10.0-9)
and anyway mod_perl seems to work fine except when using
request_class => 'MasonX::Request::WithApacheSession'

Did you rebuild mod_perl and libapreq with perl 5.10?

I thought about that too, but declaring in my handler.pl:
sub handler {
....
$HTML::Mason::Commands::dbc = DBI->connect("dbi:Pg:dbname=critik", "",
"", {RaiseError=>1, PrintError=>1, AutoCommit=>1});
....
}
and using $dbc in my mason code works fine.

My guess would be that your Postgres driver has a problem. Try
running some Pg queries from Mason.

Thanks for the pointer and fine investigative work on reducing the
problem to a perl one-liner!
Awaiting upstream now...

This looks very similar to <http://bugs.debian.org/480480>, Cc'd as
480480@bugs.debian.org . I just sent a stack backtrace there, no idea
yet if the fault is with perl or mod_perl2.
