[TIMOB-2281] iOS: option to download directly to a file

Currently it is not possible to download files larger than free memory, and XHR is prone to leaking (see http://developer.appcelerator.com/helpdesk/view/50581">http://developer.appcelerator.com/helpdesk/view/50581 for a reproducible test case). Providing the ability to save directly to a file (which is supported by ASIHTTPRequest) would work around these issues.

Big bump! Can't believe this is still a bug after so long. Hope to see this resolved soon.

Can I humbly suggest this should be more than low priority? The leak is severe and can cause devices to actually reboot if the OOM handler doesn't fire in time. If file-backing is too much work for now, I'd settle for a fix for the leak described on that helpdesk ticket.

Sure. Ralf just hasn't triaged it yet. I'll go ahead and bump this one.

Thanks a lot for this. I'm still seeing my app's memory consumption creep up over time, but it's a lot slower with this fix in place, and it should go a long ways towards reducing crashes due to memory issues.

We're aware of the memory leak problems involving XHR and will work on them as soon as possible. Bug #2299 will allow you to track our progress on this.
