Apache::DBI Segmentation fault
I am getting a segmentation fault on configtest when using Apache::DBI (using the startup.pl example in Apache::DBI Distribution). When trying to start the server I get no error messages but the server isn't running afterwards: root@ganja:/home/www/server/conf ../bin/apachectl start ../bin/apachectl start: httpd started root@ganja:/home/www/server/conf ps -ef | grep httpd lengerke 5787 27877 0 12:11 pts/500:00:00 vi httpd.conf root 6434 5760 0 12:57 pts/11 00:00:00 grep httpd root@ganja:/home/www/server/conf ../bin/apachectl configtest Syntax OK ../bin/apachectl: line 184: 6436 Segmentation fault $HTTPD -t root@ganja:/home/www/server/conf When I comment out the 'use Apache::DBI' in startup.pl all works fine. Setting $Apache::DBI::DEBUG = 2 makes no difference even in verbosity of the error_log - the server will die without any warning or error. The setup is: SuSE Linux 6.3 (i386) Apache/1.3.20 (Unix) # (enabled proxy, rewrite, so, ssl) PHP/4.0.6 # apxs-built DSO mod_perl/1.26 # apxs-built DSO mod_jk # apxs-built DSO mod_ssl/2.8.4 OpenSSL/0.9.4 Perl 5.005_03 Apache::DBI 0.88 DBI 1.14 # works fine without Apache::DBI Any help or pointers are appreciated.

Re: Apache::DBI Segmentation fault
I am getting a segmentation fault on configtest when using Apache::DBI (using the startup.pl example in Apache::DBI Distribution). When trying to start the server I get no error messages but the server isn't running afterwards Do you know that your DBI works without Apache::DBI? It would be helpful if you could post the relevant parts of your httpd.conf and startup.pl too. - Perrin
Re: Apache::DBI Segmentation fault
Hi,
I actually got this to work now. The segfault happens when I load
Apache::Registry before Apache::DBI. However, I have used the
eg/startup.pl from the Apache::DBI distribution and that has
Apache::Registry loaded before Apache::DBI... Maybe this is a bug?
My httpd.conf Perl* relevant parts:
LoadModule perl_module libexec/libperl.so
[...]
PerlRequire /home/www/server/conf/startup.pl
PerlFreshRestart on
[...]
PerlModule Apache::Registry
DirectoryMatch /home/www/hosts/[^/]*/cgi-perl
Options FollowSymLinks ExecCGI
SetHandler perl-script
PerlHandler Apache::Registry
PerlSendHeader On
AllowOverride None
Order allow,deny
Allow from all
/DirectoryMatch
[...]
Location /perl-status
SetHandler perl-script
PerlSetVar StatusOptionsAll On
PerlHandler Apache::Status
/Location
and the (fixed) startup.pl:
#!/usr/local/bin/perl -w
$ENV{GATEWAY_INTERFACE} =~ /^CGI-Perl/ or die GATEWAY_INTERFACE not Perl!;
use Apache::DBI;
use Apache::Registry;
use strict;
$Apache::DBI::DEBUG = 2;
Now if Apache::Registry is loaded before Apache::DBI in startup.pl I get
the segfault. Also, If I don't use startup.pl and put a 'PerlModule
Apache::DBI' _after_ the 'PerlModule Apache::Registry' in my httpd.conf
I also get the segfault. I am aware that any modules that use DBI must
be loaded _after_ Apache::DBI but I didn't think Apache::Registry uses
DBI, or does it?
