RegistryLoader Segmentation fault
Hello,
I'm trying to follow the script in section 214 of the book mod_perl
Developer's Cookbook in order to pre-load my Apache::registry scripts
using Apache::RegistryLoader I'm getting a seg fault when I attempt to
start apache
My startuppl is as follows:
#!/usr/local/bin/perl
use lib qw(/usr/local/apache/lib/perl);
use Apache::DBI;
use Apache::Registry;
use Apache::RegistryLoader;
use DBI;
use DBD::Pg;
use strict;
use CGI qw(-compile :all);
use DirHandle;
my $rl = Apache::RegistryLoader-new;
my $dh = DirHandle-new(/usr/local/apache/cgi-bin/chimpkit/) or die $!;
foreach my $file ($dh-read) {
next unless $file =~ m/\pl$/;
print STDOUT Pre-loading $file\n;
$rl-handler(/cgi-bin/chimpkit/$file,/usr/local/apache/cgi-bin/chimpkit/$file);
}
1;
When I attempt to start apache, I get the following messages on STDOUT:
[root@castle bin]# /apachectl start
Pre-loading chimpworkspl
Apache::Debug: [level 1]
Compiled package Apache::ROOT::cgi_2dbin::chimpkit::chimpworks_2epl
for process 27233 at
/usr/lib/perl5/site_perl/560/i386-linux/Apache/RegistryLoaderpm line 76
/apachectl: line 171: 27233 Segmentation fault (core dumped) $HTTPD
/apachectl start: httpd could not be started
[root@castle bin]#
Nothing has been written to the error log The format of my
$rl-handler() call seems ok to me I perused the archives for a while
and tried a couple of things that fixed other people's RegistryLoader
problems, to no avail Everything works fine if I comment out the call
to handler() except of course now each child has a copy of the compiled
code Any thoughts?
Thanks,
Fran

Re: RegistryLoader Segmentation fault
Ged, using Apache::RegistryLoader I'm getting a seg fault when I attempt to start apache Read mod_perl/SUPPORT Ok I've looked through it I've tried some of the quicker suggestions gdb -core core and gdb httpd core tell me: Core was generated by `/usr/local/apache/bin/httpd' Program terminated with signal 11, Segmentation fault #0 0x80ca6b6 in Perl_gv_init () I'll try some of the more involved stuff here in a moment Did you compile your own Perl, mod_perl and Apache? Yes Perl 560, mod_perl 125, apache 1319 You might be better off with Perl version 561 instead I will upgrade and see what happens Are you using DSO? No Thanks for the pointers thus far! -Fran

whoops, forgot to CC the list, but it seems Ged stepped in with the same info Fran Fabrizio wrote: Hello, I'm trying to follow the script in section 214 of the book mod_perl Developer's Cookbook in order to pre-load my Apache::registry scripts using Apache::RegistryLoader I'm getting a seg fault when I attempt to start apache I've never seen a segfault with RegistryLoader, but there are a few avenues that might help see Recipe 919 for a general introduction into using gbd and getting a backtrace, as well as the SUPPORT document in the mod_perl sources maybe someone else has seen this before and can offer more help --Geoff
