* style: Make MatchingContext generic over SelectorImpl.Emilio Cobos Álvarez2017-10-191-20/+26
| | | | | This will help Xidorn implement tree pseudos, and in general makes sense, allowing to put specific matching data in a selectors implementation.
* Replace all uses of the `heapsize` crate with `malloc_size_of`.Nicholas Nethercote2017-10-181-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Servo currently uses `heapsize`, but Stylo/Gecko use `malloc_size_of`. `malloc_size_of` is better -- it handles various cases that `heapsize` does not -- so this patch changes Servo to use `malloc_size_of`. This patch makes the following changes to the `malloc_size_of` crate. - Adds `MallocSizeOf` trait implementations for numerous types, some built-in (e.g. `VecDeque`), some external and Servo-only (e.g. `string_cache`). - Makes `enclosing_size_of_op` optional, because vanilla jemalloc doesn't support that operation. - For `HashSet`/`HashMap`, falls back to a computed estimate when `enclosing_size_of_op` isn't available. - Adds an extern "C" `malloc_size_of` function that does the actual heap measurement; this is based on the same functions from the `heapsize` crate. This patch makes the following changes elsewhere. - Converts all the uses of `heapsize` to instead use `malloc_size_of`. - Disables the "heapsize"/"heap_size" feature for the external crates that provide it. - Removes the `HeapSizeOf` implementation from `hashglobe`. - Adds `ignore` annotations to a few `Rc`/`Arc`, because `malloc_size_of` doesn't derive those types, unlike `heapsize`.

* Overhaul MallocSizeOf and related things.Nicholas Nethercote2017-09-121-43/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the MallocSizeOf stuff in Stylo work more like the HeapSizeOf stuff already in Servo, except better. In particular, it adds deriving support for MallocSizeOf, which will make it easier to improve coverage. The patch does the following. - Combines servo/components/style/stylesheets/memory.rs and the heapsize crate into a new crate, malloc_size_of. - Forks the heapsize_derive crate, calling it malloc_size_of, so that MallocSizeOf can be derived. - Both the new crates have MIT/Apache licenses, like heapsize, in case they are incorporated into heapsize in the future. - Renames the methods within MallocSizeOf and the related traits so they are more concise. - Removes MallocSizeOfWithGuard. - Adds `derive(MallocSizeOf)` to a lot of types, in some cases replacing an equivalent or almost-equivalent hand-written implementation. - Adds stuff so that Rc/Arc can be handled properly.
* stylo: Add uses of fallible Vec, SmallVec and HashMap facilities.Julian Seward2017-09-101-10/+25

* style: remove selector_map::find_push.Emilio Cobos Álvarez2017-09-091-10/+4
| | | | | It has a single caller and is overly generic, which is going to make harder to add fallible allocations to it.

| | | | | | | | | | | | This shaves a fair amount of time of stylist rebuild. Most of the extra remaining overhead are memory allocations... I'll try to get those sorted out next, though fixing that may overlap quite a bit with the work Cameron is doing in bug 1382925.

| | | | | | | | | | | This commit also removes the old restyle_hints module and splits it into multiple modules under components/style/invalidation/element/.
