Bug #20987 for Clone: Severe memory leak

Subject:

Severe memory leak

I just thought I should create a bug so other people don't waste time debugging their code for memory leak (took me a while to figure out the problem is with Clone). Someone else has noticed a severe memory leak in this module. He tried to patch this one but lost contact the author; so he has created a new cpan module: Clone::More. This module should not be used any more.

How about some code examples or a least a brief explanation of where you saw the memory leak? Do I get at least one shot at fixing the leak? And just for the record I was not contacted with a patch, I was contacted with a request to take over ownership of the Clone module. On Mon Aug 14 13:19:39 2006, hpham wrote: Show quoted text

Sorry, I thought you weren't maintaining this module anymore. The bug occurs in mod_perl (2.0.2) environment on Apache 2.0.58, Windows XP. Over a thoudsand requests on the same page, it leaks around 10MBs. Our set up is a bit complicated, I will see if I can get a strip down version. Also, even though Clone::More reduces lots of leak, I believe it mysteriously crashes mod_perl (and so Apache) once in a while. On Fri Aug 18 23:16:04 2006, RDF wrote: Show quoted text

Hi. I've created experimental patch that should fix at least one leak in Clone module I know about. You can download it from a ticket [*]. Can you test that it works for you?

Hi Ruslan, I did test that your patch fixes the leak. I'm on vacation right now, I'll try to get a new version uploaded sometime next week after I get home. Ray Finch finchray@nventure.com Show quoted text
