Created attachment 577193 [details] [diff] [review] patch I'm converting existing memory reporters to use mallocSizeOf. See https://wiki.mozilla.org/Memory_Reporting for details about why I'm doing this. This patch changes the "prefixset" memory reporter accordingly. As part of this change, I removed nsUrlClassifierPrefixSet::SizeOfIncludingThis from the IDL, because there's no need for SizeOf-style functions to be exposed via IDL; no other such functions are exposed in this way. That change simplifies it significantly.
Gian-Carlo, can you do this review soon? It's a very small patch and it's blocking several pieces of my memory reporter work. Thanks!
Comment on attachment 577193 [details] [diff] [review] patch You changed the UUID without updating everything. You'll need to update toolkit/components/build/nsToolkitCompsCID.h as well or things are going to break. r+ if that is fixed.
