Hi, I wish to setup a GUI debugging environment for my CGI, which is running
using apache mod_perl
I update the following file (/usr/local/apache_modperl/conf/httpd.conf) to the
below content :-
### Start to hack by Cheok
<Perl>
use Apache::DB();
Apache::DB->init;
</Perl>
<Location />
PerlFixupHandler Apache::DB
</Location>
### End to hack by Cheok
and the following file (/usr/local/lib/perl/5.8.8/Apache/DB.pm)
if (!$loaded_db) {
# Fallback
# require 'Apache/perl5db.pl';
# Hacked by Cheok
require Devel::ptkdb;
}
When I launch a web site, I get the following error log :-
[yanchengdev] [modperl] Prototype mismatch: sub CORE::GLOBAL::exit: none vs
(;$) at /usr/local/lib/perl/5.8.8/Tk.pm line 414. [failed] [Connection refused]
[yanchengdev] [modperl] [Wed Nov 5 10:48:53 2008] [notice] child pid 15698 exit
signal Segmentation fault (11) [success]
[yanchengdev] [modperl] Prototype mismatch: sub CORE::GLOBAL::exit: none vs
(;$) at /usr/local/lib/perl/5.8.8/Tk.pm line 414. [failed] [Connection refused]
[yanchengdev] [modperl] [Wed Nov 5 10:48:54 2008] [notice] child pid 15699 exit
signal Segmentation fault (11) [success]
OK. I temporary solve the problem by comment out the line
## *CORE::GLOBAL::exit = \&exit;
I try to test whether TK/Perl debugging tool still work by
(1) ssh -X [EMAIL PROTECTED]
(2) cat cheok.cgi
#!/usr/bin/perl5 -Twd:ptkdb
print "Hello World From Cheok.\n";
print "Good Bye World.\n";
(3) /usr/bin/perl5 -T cheok.cgi
OK. The GUI windows shown up, and I can perform step debugging.
Now, I try to test on the web site. I want to start my apache in single process
mode. Hence, I edit the following files
/usr/local/apache_modperl/bin/apachectl
/etc/init.d/apache
to content (I just add -X flag)
case "$1" in
start)
log_begin_msg "Starting $NAME 1.3 web server..."
if $ENV $SSD --start --pidfile $PIDFILE --make-pidfile $PIDFILE --exec $DAEMON
--oknodo --verbose -- -X -f $CONF; then
Then I run
yanchengdev:/$ /usr/local/apache_modperl/bin/apachectl stop
Stopping apache 1.3 web server....
yanchengdev:/$ /usr/local/apache_modperl/bin/apachectl start
Starting apache 1.3 web server...GnuPlot already exists in [/tmp/]. Skipping
copy.

Regenerating autold...done.
[notice] Apache::DB initialized in child 17975
GnuPlot already exists in [/tmp/]. Skipping copy.
PRELOADING SCRIPTS...
Regenerating autold...done.
I use my browser to request cheok.cgi
The web page is displayed at browser. But there are no GUI debugger windows at
all.
I check the error log file in apache, there isn't any error :(
Any hint? I am lost...
