File Handle problems - mod_perl 2.0

["Justin Luster" <suppressed>]

Hi,

 

Recently I’ve noticed intermittent problems in the behavior of my code when running under Mod_Perl 2.0.  This particular code has been out there for years with no problems.  Recently I’ve seen a few problems and I’m wondering if it has anything to do with Mod_Perl 2.0, it has been running fine under Mod_Perl 1 for years.

 

Basically the problem that I see is once in a while when the file is opened the file offset does not appear to be at the beginning of the file.  After a file is opened I assume the file reader is at the beginning of the file but once in a while it seems like it is reading from the middle of the file after it is opened.  Most of the time the code works just fine.  Here is the code:

 

            open (authlib::QUESTIONFILE,'<' . $authlib::GlobalPaths[0] . $strQstName) or authlib::ssiDie("Can't open the file $strQstName,\n", $!, 1);

            binmode authlib::QUESTIONFILE;

 

            #Get first line

            $_ = <authlib::QUESTIONFILE>;

            # Here is where it fails from time to time getting a different line (not the first line in the file).

 

Does anyone have any idea what is going on?  Is this a Mod_Perl 2.0 thing?

 

We are only using Mod_Perl’s registry to speed up our Perl scripts.  Here is what we have in the Apache configuration file:

 

<IfModule mod_perl.c>

                                    <Files ~ (\.pl)>

                                                SetHandler perl-script

                                                PerlResponseHandler ModPerl::Registry

                                                PerlOptions +ParseHeaders

                                                Options +ExecCGI

                                                Order allow,deny

                                                Allow from all

                                    </Files>

                        </IfModule>

 

Thanks for your help,
