in reply to Re^2: symbols, scope, and mod_perl
in thread symbols, scope, and mod_perl

Furthermore each script running under registry gets its own namespace, ex

ModPerl::ROOT::ModPerl::Registry::D_3a_ro_sham_bo_theEXAMPLEXPORTERtes +t::my_dirt_sneaky_object_reference

Re^4: symbols, scope, and mod_perl

    You are right. To be more precise, I am actually allocating the object on thread symbol table, but under mod_perl objects in "main" threads functions are persistent between calls. So it gets messed on subsequent calls. To avoid this it is needed to use a lexical variable, that does not allocate on the symbol table. To achieve the same behavior as per cgi environment, I should manipulate what it is called "stack scratchpad", but I do not have such skills.

      You are right. ...

      Are you saying you're using threads in your program?

        I am testing the trick also in mod_perl, under Worker MPM. So, yes, I am definitely using threads.

      Well, you really shouldn't be exporting this object if its not a singleton

      use EXAMPLE(); my $poop = EXAMPLE->new; $poop->my_example_method; print "mission accomplished\n";
        If you have a look at the code I posted, you can see that the trick I am testing consists actually in putting an instance of the object in the "main" namespace without using Exporter and without declaring/instantiating the object from the cgi. In fact the class calls its own constructor when you use it.
