eog caches too many images

Thanks for your bug. How do you know what image is cached? Do you use the "image collection" option? That seems a feature to me, if you use the image collection you probably want the option to browse the other pictures from the same directory. If you don't want that maybe you should not activate the image collection pane?

I agree with the reporter. If you open say a CD with a large folder of photos, eog quite happily eats all available CPU, I/O and memory caching the photos in the folder.
The intention of caching is to improve responsiveness however what ends up happening is that eog uses lots of virtual memory.

I think that the caching thread probably needs to be a lot more conservative, maybe it should have a little sleep between reading images. Also it probably needs to only read a few files before and after the displayed image.

Martin, do you use the collection option or not?

I know it's caching because when I run eog from a command line it outputs a message as it caches each image.

As far as the "collection option" goes, the only place where I see an option is under the view menu--and it is not checked. My preferred default behavior is to view a single image at a time.

Even so, the problem is not so much the collection option as it is that ***eog caches every image in the directory even though only 1 image was selected for viewing***. When 2 or more are selected, it only caches the selected images.

No, I don't know nothing about the collection option. (This is from a fresh dapper install). If you just insert a CD of images and start viewing them , this undesirable caching occurs

the collection option is the banner with the previews you get on the bottom of the window, you can activate it by using the "F9" key of your keyboard or the menu

marking as unconfirmed if somebody wants to take that upstream which is the right place for it
