Reviewed by Darin Adler. Should make use of purge priorities for different resource types https://bugs.webkit.org/show_bug.cgi?id=48684 Assign purge priorities to CachedResource objects. JavaScript and CSS stylesheets are more important than images so hint to the kernel to purge them last. We do this by repurposing the previously unused function, PurgeableBuffer::setPurgePriority(). It now just sets the priority field and does not have side-effects like calling makePurgeable(true). Also, remove unusued PurgeableBuffer::create(const Vector<char>&) function and move the purgeable memory size threshold from CachedResource to PurgeableBuffer. * WebCore.xcodeproj/project.pbxproj: Add new PurgePriority.h header and mark it as private header. * loader/CachedCSSStyleSheet.h: (WebCore::CachedCSSStyleSheet::purgePriority): * loader/CachedImage.h: (WebCore::CachedImage::purgePriority): * loader/CachedResource.cpp: (WebCore::CachedResource::makePurgeable): Set the purge priority on the PurgeableBffer. Also, move the check for purgeable size threshold to PurgeableBuffer. * loader/CachedResource.h: (WebCore::CachedResource::purgePriority): Added. New virtual method that lets the class specify its purge priority. * loader/CachedScript.h: (WebCore::CachedScript::purgePriority): * platform/PurgePriority.h: Added. Move the PurgePriority enum from PurgeableBuffer class to its own header file. (WebCore::): * platform/PurgeableBuffer.h: (WebCore::PurgeableBuffer::setPurgePriority): Update this previously unused function to just set the priority and not call makePurgeable(true). * platform/mac/PurgeableBufferMac.cpp: Update size threshold to 16KB which is what CachedResource was using. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@71318 268f45cc-cd09-0410-ab3c-d52691b4dbfc
