[Flashcoders] Memory leaks using XML in Flash Lite 3
I've been fighting memory leaks. I've narrowed it down to use of XML class, but only if I actually parse the data. Using onData doesn't leak, onLoad leaks, parseXML leaks and new XML(str) leaks. Any Ideas? Thanks ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
[Flashcoders] Memory Leaks
Hi Flashcoders, What techniques do list members use for tracking down memory leaks in AS2? It's a problem with repetitive functions called by setInterval events. It's slow and cumulative but if you leave it on you can see the PF and Mem Usage, creep up. Can anyone out there share any of their tips, I'm tearing my hair out here, Thanks, Michael Michael Trim Senior Producer Instant Business a: 8-10 Colston Avenue, Bristol, UK, BS1 4ST t: +44 (0) 117 915 5175 msn: [EMAIL PROTECTED] w: www.ibltd.com Company number: 03857884 Registered office: Prospero House 46 -48 Rothesay Road, Luton, Bedfordshire, LU1 1QZ VAT Registration No. GB 753 1706 40 The information in this email is confidential and is intended solely for the addressee.

Re: [Flashcoders] Memory Leaks
Usually I just track them down, figure out where my setInterval calls are and try to plot out in what situations they aren't being cleared. You could also put some trace calls in the classes or methods you think are clearing, and if it stops tracing then you know it's gone from memory. Additionally you might want to look into better organizing your setInterval. Maybe put them in an array that you can query. When you clear the interval set that index to null. You could trace the array and see all the non-null values. Maybe you could also make a class to manage your setInterval calls better. A clearAllIntervals method in a interval management class could help out a great deal. I've also had problems before with Delegate memory leaks. There was a great article on Delegate memory management in the last year or so - I can't remember where it was, but you can find a similar one here: http://teknision.blogspot.com/2005/07/delegatesbe-careful.html ben Michael Trim wrote: Hi Flashcoders, What techniques do list members use for tracking down memory leaks in AS2?

Use while instead of for loop statements. for will eat your resources, big time. --Carl On 5/9/07, ben gomez farrell [EMAIL PROTECTED] wrote: Usually I just track them down, figure out where my setInterval calls are and try to plot out in what situations they aren't being cleared.

Re: [Flashcoders] Memory Leaks
Look into the BitmapData memory leak issue. http://www.gskinner.com/blog/archives/2005/10/major_flash_pla.html Failing that, look for circular references, or unused objects that you never delete. --- Michael Trim [EMAIL PROTECTED] wrote: Hi Flashcoders, What techniques do list members use for tracking down memory leaks in AS2?
