I'm in need of knowing hardare specs (pagesize, memory size, cpus) to create a dynamic limit for history entries, so i can adapt history storage capabilities based on hardware we are running on. I thought system-info was exposing them, but instead it's only exposing a subset of the available data. Names are arguable, maybe instead of "cpus" could be "cpucount", not sure. I added a small test just to ensure all expected properties are there, i can run on tryserver to check how various archs respond to this. But first of all i'd like to have a guess if this could be fine or not.

Comment on attachment 409100 [details] [diff] [review] patch v1.0 I'm a little skeptical that NSPR is going to give us good data for all of these properties, but that's probably a different bug.

yeah i still have to check how "real" are them, but for now i need them exposed, especially the memsize, that we already use in Places to size the number of cached pages, should work fine. what about names? do you think "cpucount" is better than "cpus"?

pushed with "cpucount" as name, since sounds better and more widely used. http://hg.mozilla.org/mozilla-central/rev/b7ad076f2d62
