如何访问 Perl 哈希的引用计数? [英] How can I access the ref count of a Perl hash?

问题描述

我试图让我的脚本的垃圾收集器做得更好.它应该能够回收大量内存，但有些东西阻止了它.

I'm trying to enable the garbage collector of my script to do a better job. There's a ton of memory that it should be able to reclaim, but something is stopping it.

我使用过Devel::Cycle，这让我能够靠近一点，但我还没到.

I've used Devel::Cycle a bit and that's allowed me to get closer but I'm not quite there.

如何找出 Perl 哈希(我的对象的存储)的当前引用计数?

How do I find out the current reference count for a Perl hash (the storage for my objects)?

有没有办法跟踪谁持有对象的引用?也许是一种领带说，每当有人指出这个对象时，记住那个人是谁.

Is there a way to track who is holding a reference to an object? Perhaps a sort of Tie that says, whenever someone points are this object, remember who that someone is.
