Intermittent error in Included script
All:
1) I'm getting an intermittent error while executing a script. Here is
the code:
#==================================
<h1>Test</h1>
<%
print <<EOF;
The following is a test of ASP and the
use of a handrolled PM file NOT on the perl/site path.<P>
EOF
print "Current week of year: " . WeekOfYear();
print "Week of year for May 1, 2002: " . WeekOfYear(2002,5,1);
print "<p>";
%>
# =====================================
2) Intermittently, the script works, or fails with a "Undefined
subroutine" error associated with "WeekOfYear"
3) The subroutine "WeekOfYear" is contained in a handrolled PM file. On
this server I don't have admin access, so I'm PUSHing the location of
the PM file onto the INC using the following code in my global.asa:
==========
BEGIN{
push @INC,"/export/admin/jleonard/globals/ISG/CourseTools/blib/lib";
}
use HTML::TreeBuilder;
use ISG::CourseTools;
==========
My Script_OnStart, etc. are empty.
4) I'm running mostly defaults in the .htaccess file:
PerlSetVar Global /export/admin/jleonard/globals/200202
PerlSetVar IncludesDir /export/admin/jleonard/globals/common
PerlSetVar StateDir /tmp/200202
PerlSetVar Debug -3
PerlSetVar TimeHiRes 1
PerlSetVar UseStrict 1
5) Here is a log dump when the script works:

Sorry to take so long to get back to you on this. I am still getting
caught up from the holidays!
The only thing I can think of is that maybe StatScripts was set to 0, but
I didn't see the config info in your Debug error_log output to confirm.
So make sure that PerlSetVar StatScripts 1 is set ( which is the default )...
If there was a global.asa compiled that did not import WeekOfYear, and
StatScripts was set to 0 & then you added the WeekOfYear import to global.asa,
I could see how you might get this error if only intermittently.
If you continue to have problems with this, try to emails a bit of
error_log with Debug set to -3 from a fresh server restart to this
problem occuring, that could help diagnose this better.

No, just for including ASP includes.

Let me know if I can help any more.

WeekOfYear()is exported in ISG::CourseTools. The ISG::CourseTools
module was created using "h2xs" from the command line. My module test
script "t/weekofyear.t" works properly. Here is the top of my module:
===================================
package ISG::CourseTools;
require 5.005_62;
use strict;
use warnings;
require Exporter;
use AutoLoader qw(AUTOLOAD);
use Time::Local;
use Time::localtime;
our @ISA = qw(Exporter);
# Items to export into callers namespace by default. Note: do not export
# names by default without a very good reason. Use EXPORT_OK instead.
# Do not simply export all your public functions/methods/constants.
# This allows declaration use ISG::CourseTools ':all';
# If you do not need this, moving things directly into @EXPORT or
@EXPORT_OK
# will save memory.
our %EXPORT_TAGS = ( 'all' => [ qw(
WeekOfYear
) ] );
our @EXPORT_OK = ( @{ $EXPORT_TAGS{'all'} } );
our @EXPORT = qw(
WeekOfYear
);
================================

Does "IncludeDir" also apply to any and all "use" commands?

StatINC is set to the default (0). I explicitly set it and still get
the same intermittent problem.
I'll keep plugging.

In what package is WeekOfYear() defined and how it is supposed to be
exported into the global.asa package? Is it using Exporter?
Make sure that the package that defines WeekOfYear() and exports
it is used in global.asa so the import of WeekOfYear() can occur.
Also make sure that WeekOfYear is being explicitly exported.
Instead of BEGIN {}, try using "use lib qw(/path/)" for the
same effect. This is not related to your problem, just cleaner.

FYI, Global acts an an IncludesDir... IncludesDir is nice when
you want to share includes accross applications.
If you get to the end of the line, and you need to make this work
try something like this in global.asa:
use Package;
*WeekOfYear = *Package::WeekOfYear;
This is by no means ideal, but if this works, and nothing else
does, this may give us some clues.
If you are using StatINC or StatINCMatch settings, try turning
them off & see if that makes a difference.
