( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I have the END{} block on some module.
It is use()d by some script, to 'todo' script.
The 'preload' script does the do() on it. Both execute the code in the context of the package main;
The 'preload' script fork()s then and the compiled module's machine code is shared among the forks.
The problem is: if I put the 'use module;' or 'do "";' on the 'preload' script no matter if it is before the do() of the or after, the END{} of the module gets to be executed twice.
I suppose there should be the built-in variable that keeps the used modules each time they use to be loaded. This is not the %INC because the is the key of that hash.
There is certainly a condition on the rest of the code that influenced the code to behave like that, I could not reproduce all of that at the moment being with the vanilla plain module, todo and preload files to put them here as a simple sample of the code. Although the reproduceable code itself is a no secret at all. I am sure it should be obvious for some kind Monk to know such a stuff. ;-)
Thank you.
