[webkit-dev] Regarding cache memory leaks

[sumanrapolu at aim.com]

 Hi Holger,



 When we use the default cache model i.e 8MB cache size in this case it is storing the images beyond the 8MB that is untill complete RAM memory. So we disabled the cache by using WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER  even though the images and JS are storing in the Cache. We observed this by printing dumpStats output.

Can you please suggest us how to disable the cache properly ?


we are using webkit-1.2.3 and cross compiled for MIPS platform with gtk-directfb backend.

Thanks In Advance.

Thanks,
Suman

Dear All,

We are working on webkitGtk ( with gtk-directfb backend )  and ported for MIPS 
platform. We observed there are memory leaks with PNG/JPG image rendering. I am 
using webkit-1.2.3 version and I set cache model to WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER.

When I am printing the dumpStats I could able to see the Image count and live && 
decoded image sizes. Even I disabled the cache it is storing on to cache.
could you please suggest me is there any patch to avoid image related memory 
leaks with webkitGtk. Please help me on this.

Thanks In Advance.

How do you know it is leaked? If you are currently viewing these images you
will most likely have the encoded and decoded version around. Do you have a
test case to show the memory leak?

I don't see a Tiger buildbot anymore.  Does that mean I'm allowed to
break the Tiger build?  If so, can we rip out all the Tiger-specific
code?

Adam
