[CORE?] Heap Low - Page 2

Wouldnt a bug in the compiler be what causes a heap low error anyways?

BAILOPAN · 10-24-2006 , 17:55 Re: [CORE?] Heap Low

Unfortunately the error is a bit ambiguous and I think I'll change the message next major release. Heap low should mean "there is no heap space left," which can mean a memory leak in the VM or a native. But in some cases it also erroneously means "heap error," as in the heap crossed under its own minimum boundary.

Only the latter is usually a compiler a bug.

hmm... "there is no heap space left." could that mean that i am overrunning the memory constrictions my machine allocates me? my plugins are QUITE QUITE QUITE (quite quite quite) large, using LOADS of memory. (very inefficiant, i ought to recode them -_-).

Yeah, but basically, can heap low mean no more memory left?

No, that won't happen. The only thing you can be doing is running out of plugin memory (allocated with #pragma dynamic).

doubleM · 11-06-2006 , 07:18 Re: [CORE?] Heap Low

ok... so would running out of plugin memory do a heap low?

BAILOPAN · 11-06-2006 , 13:45 Re: [CORE?] Heap Low

It could. Although as I said, the error message is ambiguous, so I have to change it in the next major release (1.77) to know for sure.

If you would like I can attach an early build here that has the change.

yes, please! 8| lol

oh, also as sorta off topic, would you recommend the array 3.14 module? i use lots of giant static arrays in my plugins (meant to be dynamically sized -_-) that i usually use in a push-pop method (this is what is causing my giant memory usage). I was just wondeing what you thought of the module, i havnt seen many people using it.

BAIL any chance you can make a recommendation on how to determine what you should set

#pragma dynamic

to? I'm having this exact same issue with war3x and have never been able to figure out how to get it to go away :/ (It happens after playing for a while, not really debuggable I don't think)

BAILOPAN · 11-11-2006 , 14:01 Re: [CORE?] Heap Low

My mistake. Core is already differentiating these errors correctly. For some reason in my mind I thought it wasn't. Changing the plugin memory should not affect this error. Proof: You should be able to output the value of heapspace() periodically, preferably close to where you get the error, and you should never see it dip seriously below what your requirements are.

There's a lot of things I can do to help you debug - the best off the top of my head would be having Core log heap info before and after each function call. But before I do that, I found an interesting bug in the forward API dealing with the heap. In theory it's unrelated but I'd like to see if it's a surprise magic fix.

If the attached binary doesn't work, I'll start making heap logging ones for you. But ultimately the best thing would still be me having a copy of your setup which can reproduce the problem ;)

TY bail, I"m going to run war3x w/32 bots w/this to test it out...
