required files not in a namespace?

Are “required” files in a namespace under Apache::Registry in Mod_Perl? I have just done a simple test that seems to show that they are not in a namespace. In the documentation (http://perl.apache.org/docs/1.0/guide/intro.html#Apache__Registry) it says that the initial script is stored under a unique key to “prevent script name collisions”. This seems to work for the main script that you call but not for the “required” files that that script uses.

Here is my example:

Test1 Directory

test1.pl

libone.pl

Test2 Directory

test1.pl

libone.pl

test1.pl contains:

print "Content-type: text/html\n\n";

print "<html>";

print "<head>";

print "<title>Debug Test #1</title>";

print "</head>";

print "<body>";

require "libone.pl";

libone::A();

print "<h1>Debug Test #1 Successful</h1>";

print "</body>\n</html>\n";

libone.pl contains:

#!/usr/bin/perl

package libone;

sub A

{

print "Hello from A";

}

return 1;

In the 2^nd copy of libone.pl, contained under the Test2 directory I changed the output slightly to say "Hello from A - 2nd version".

I then restart Apache and try test1.pl from the Test1 directory and I see “Hello from A”. I then try the test1.pl from the Test2 directory and I still get "Hello from A”. If I restart Apache and try test1.pl from the Test2 directory first I see "Hello from A - 2nd version". If I then try test1.pl from the Test1 directory I still get "Hello from A - 2nd version".

So it appears as though Apache::Registry is caching the first instance of libone.pl and is not namespacing it as it does with the initial script test1.pl.

If this is the case what can I do to fix it? I view it as a big problem because if my script is deployed I do not know if my script is going to use my libone.pl or a libone.pl written by someone else that has already been stored in the cache.

I hope you understand my problem. Please help.

Thanks.
