*Summary* Expose a property on navigator called hardwareConcurrency that returns the number of logical cores on a machine. *Motivation* All native platforms expose this property, It's reasonable to expose the same capabilities that native applications get so web applications can be developed with equivalent features and performance. *Mozilla bug* https://bugzilla.mozilla.org/show_bug.cgi?id=1008453 The patch is currently not behind a runtime flag, but I could add it if requested. *Concerns* The original proposal required that a platform must return the exact number of logical CPU cores. To mitigate the fingerprinting concern, the proposal was updated so a user agent can "lie" about this. In the case of WebKit, it will return a maximum of 8 logical cores so high value machines can't be discovered. (Note that it's already possible to do a rough estimate of the number of cores) *Compatibility Risk* Blink: approved for implementation and shipping [1] WebKit: almost approved for implementation [2] Internet Explorer: No public signals Web developers: Positive 1: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/xwl0ab20hVc 2: https://bugs.webkit.org/show_bug.cgi?id=132588 https://lists.webkit.org/pipermail/webkit-dev/2014-May/026511.html _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
