This changeset implements the beginnings of fine-grained measurement of Servo's data structures. - It adds a new `SizeOf` trait, which is used to measure the memory used by heap data structures, and implements it for some std types: Box, String, Option, Arc, Vec, and DList. - It adds a new `MemoryReporter` trait which is used to report memory measurements from other threads to the memory profiler. Reporters are registered and unregistered with the memory profiler, and the memory profiler makes measurement requests of reporters when necessary. - It plumbs a MemoryProfilerChan through to the layout task so it can register a memory reporter. - It implements the `SizeOf` trait for `DisplayList` and associated types, and adds a memory reporter that uses it. The display list hits 14.77 MiB when viewing tests/html/perf-rainbow.html, and 2.51 MiB when viewing the Guardians of the Galaxy Wikipedia page from servo-static-suite. Example output: 0.29: display-list::http://www.reddit.com/ 0.00: display-list::http://static.adzerk.net/reddit/ads.html?sr=-reddit.com,loggedout&bust2#http://www.reddit.com 0.00: display-list::http://www.reddit.com/static/createadframe.html There are a number of FIXME comments indicating sub-optimal things. This is a big enough change for now that doing them as follow-ups seems best. |
