Subroutine xxx redefined

[Bart van Kuik <b....@sron.nl>]

Hi list,

I'm using Apache::PerlRun to run my Perl scripts. I'm getting the 
following error:

Subroutine xxx redefined at /path/to/sirq.pl line 100.
Subroutine xxy redefined at /path/to/sirq.pl line 200.
Subroutine xxz redefined at /path/to/sirq.pl line 300.

I can't find in the guide what I'm doing wrong.

Some version info:
Slackware Linux 10.1 with a custom compiled Apache/1.3.33 and 
mod_perl/1.29. Perl version 5.8.6.

Piece of httpd.conf for the directory concerned:

<Directory /home/*/public_html>
     Options MultiViews Indexes FollowSymlinks ExecCGI
     <Files *pl>
         SetHandler perl-script
         PerlHandler Apache::PerlRun
         Options ExecCGI FollowSymLinks
         allow from all
         PerlSendHeader On
     </Files>
</Directory>

Thanks,
Bart

The same every time?  That's very strange.  I'd start adding some debug
statements to Apache::PerlRun to make sure it really is handling this
script.  In particular, I'd put some warnings in the flush_namespace()
sub to see if it is trying to clear out that sub or not.

One possible explanation for this behavior is that something which did
not warn in older versions of perl (when it was more likely to be
running mod_perl 1 and Apache::PerlRun) now does.  In that case, it
should be possible to patch PerlRun to suppress the warning.  But first,
make sure PerlRun is really running your script and clearing the symbol
table afterward.

Apologies, it shows a lot more detail for Apache::Registry but not for
PerlRun.  You can browse the symbol table of loaded packages though, I
believe, which would include the package generated for your script.

No.

The before-mentioned piece of script gives the following warning:
Subroutine testsub redefined at /home/bartvk/public_html/tscu/test.pl 
line 7.

I installed this module, went to the main screen -> Loaded Modules. For 
Apache::PerlRun, it says:

Apache::PerlRun	0.00	Sat Mar 8 03:11:09 2003 
/home/apache_mod_perl/lib/perl5/site_perl/5.8.6/i486-linux/Apache/PerlRun.pm

Clicking on the module name gives a screen with a list of functions; I 
don't really see how to get more information on PerlRun.

Thanks,
Bart
