Well, didn't figure you would get literal on me...my fault for not being more clear.Like leaking memory large or just larger? Unfortunately, the latter, as you well know, is going to happen to some degree with any library cache technology.
Just large. I've never had a memory leak in any Perl. I've had canversations
with the Perl Developers and it seems to be all but impossible. The causes of most
emory "leaks" in Perl is with the code where you keep creating objects and never scope them out of the program. Misunderstanding of scope is a huge program with
mod_perl, because the damn program never ends.
I am not aware of any way for Perl to leak memory. But if you show me the modules,
id be happy to pass them to Mike.
They were all problems with scope. C/C++ memory allocation leaks are indeed impossible in Perl. Mine was accidental, since I understand the problem and scoping, thanks tho.
I generally go by the definition that a memory leak is anything that does not free memory use properly, resulting in ever increasing memory usage until all real and virtual memory has been used up and the program and/or the OS fails.
When talking about perl, my assumption is that the reader already knows that malloc() and friends do not apply here.
Going to skip a response to CS 101, been there, done that. Hope some people found it useful, it was a good write up.
Depending on the problem, I would probibly not attack this in this way in the first place. 80 megabytes of data need to be stored, IMO, in a database...not a flat file
Well, sometimes the problem dictates itself. Infact, one could almost see this as part of a slogan for perl.
A relatively new perl user had a problem to solve. He was trying to be heoric and introduce the glory of perl to his company by whiping out a script to parse some monster file they ended up with from a customer. He did, and by his calculations it would be done in 3 days, which wasn't going to cut it. The first person to respond to his plea for help said he should use C or C++. On perl monks even... Myself and one other poster cut down his runtime to a point that allowed him to do it in the time he had and still in perl.
Alas, I think we have managed to entirely hijack this thread.
I will check it out. Nice idea. Maybe you do it already, but finding donors for scholarships & systems might be a good way to help get in people who really could use the boost in education.Join us on NYLXS at http://ww.nylxs.com . The mane mail list is hangout. But be warned that we are not a technology group, but an educational non-profit. That means our emphaisis is on education, not the hot tech topic of the day :)
