File Handle Issues in Mod_Perl 2.0

["Justin Luster" <suppressed>]

Hi,

 

A while back I posted an issue that I was having with mod_perl 2.0 regarding file handles.  Today I found an interesting clue to the problem.

 

In my test script below I’m opening the same file twice in a row on purpose without closing it.  I’m trying to replicate a possible error condition where the file might not be closed properly.  When I run this script on Apache 1.3 outside of Mod_Perl it works fine.  When I run this script on Apache 1.3 with Mod_Perl 1.0 it works fine.  When I run this script under Apache 2.0 Mod_Perl 2.0 it breaks (I’m on Red Hat Linux).  Basically on the 2^nd open the file offset does not start at the beginning of the file as it does in my other tests.  Further more it is not consistent but starts doing the Mod_Perl weirdness of sometimes working and sometimes not.

 

The code that is breaking has been working for years but has started to show errors when run under Mod_Perl 2.0 Apache 2.0.

Does anyone know what might have changed in Mod_Perl 2.0 to have caused this problem?

 

Thanks for your help, 

 

Justin

 

Here is my test script:

 

            my $strCGIPath = "";

 

            if ((exists($ENV{'SCRIPT_FILENAME'}) || (defined ($ENV{'SCRIPT_FILENAME'}))))

            {

                        #Get absolute path to cgi-bin

                        $strCGIPath = $ENV{'SCRIPT_FILENAME'};

            }

 

            $strCGIPath =~ s/\/test.pl//;

 

            my $strFileName = $strCGIPath . "/" . "test.txt";

 

            open (QUESTIONFILE,'<' . $strFileName) or print "Cant find file";

            binmode QUESTIONFILE;

 

            #Get first line

            $_ = <QUESTIONFILE>;

 

            open (QUESTIONFILE,'<' . $strFileName) or print "Cant find file";

            binmode QUESTIONFILE;

            seek QUESTIONFILE, 0, 0;

 

            #Get first line

            $_ = <QUESTIONFILE>;

 

            print $_;
