Regarding subs and global.asa
Hello all,
I am sure this is quite the newbie question, but alas, a newbie I am :)
I keep getting errors that say I am trying to use an undefined sub. The
error (regardless of which sub it points out) is in the following form in
the error log:
<quote>
[Sat Oct 5 08:34:24 2002] [error] [asp] [2246] [error] Undefined subroutine
&Apache::ASP::Compiles::__ASP__tmpx9936a616c549519afe239b14a8568b6c::mysub
called at index.asp line 210. <--> ,
/usr/lib/perl5/site_perl/5.6.0/Apache/ASP.pm line 1413
</quote>
In this case, I am calling the sub in this manner in the program:
&mysub()
My global.asa is set up as follows:
#global.asa
sub mysub{
...lots o' code...
}
I have tried with all my might to find the answer to this conundrum on the
web site and archives, but I am newbie enough not to be able to put together
the clues...
Any ideas, comments, tongue-lashings? <g>
Thanks in advance,
Thom Crane

At least on my server, I can add PerlSetVar configs to .htaccess.

Where is PerlSetVar defined? I don't have access to the server, therefore I
can make no changes to httpd.conf. Can I define it in .htaccess?

As dave pointed out, this is where the ASP events definitions reside.
However, since the global.asa is also compiled into the same perl
package as the rest of the scripts & includes in your application,
common subroutines & globals can be defined in there too for use
in your application.
The trick with getting global.asa to be compiled is your PerlSetVar Global
setting needs to point to the location it resides at. If your
global.asa resides in the same directory as your scripts, then set
Global to . If you would like your $Session & $Application files
not stored in ./.state in this case ( the default ), then you can
set StateDir to some other directory ( like /tmp/my_asp_app )

Doing a require on global.asa has a similar effect, but you should allow
for Apache::ASP to reload your global.asa, which it will do correctly
whenever you change it.

Josh

Thom:
I think global.asa is only supposed to contain event-triggered
(*_On*) subroutines and maybe local subs called by the _On subs. The
best place I've found for non-event-triggered subs is in separate
modules. You can pre-load and pre-compile frequently used modules in
Application_OnStart though and then refer to them from any page.
Application_OnStart is only for GLOBAL stuff though, and I think
changes require an Apache restart (in contrast to Script_OnStart,
which is apparently re-compiled/executed every time). This also
means changes to the modules being loaded will require an Apache
restart since they are only loaded and compiled once. (I could be
wrong as I'm not the expert; this is just the behavior I've observed.)
For example, part of my global.asa might look like this.
#global.asa
sub Application_OnStart {
use InputProcessor;
use UserCheck;
# read in global config params (e.g. db connect strings)
open (CFG, '/outside/of/web/tree/app.cfg');
while (<CFG>) {
chomp;
my ($key, $value) = split;
$Application->{$key} = $value;
}
close CFG;
}
Then, for example, in login.asp I just say
#login.asp
...(html)...
<%
my $userCheck = new UserCheck;
if ($userCheck->checkUser($ASPObjects)) {
$Response->Redirect(...)
}
else { #...etc.
%>
hope this helps! If not, at least I tried :)

Please forgive my hastiness to get this problem solved.
I have used require "global.asa" to get my problem worked out, but this
doesn't seem to be the proper way of handling this file from the reading I
have done.
Although not stated explicitly, it has been my feeling from reading at the
site and on this list that global.asa has some higher purpose than just
being another include file.
Is using a require the proper way to handle this? If not, would some kind
soul (who has nothing better to do this weekend), please help out a
burgeoning Apache::ASP user with some basics?
Thanks so much.
Thom
