* script: Create a `CrossProcessInstant` to enable serializable monotonic time ↵Martin Robinson2024-09-051-103/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#33282) Up until now, Servo was using a very old version of time to get a cross-process monotonic timestamp (using `time::precise_time_ns()`). This change replaces the usage of old time with a new serializable monotonic time called `CrossProcessInstant` and uses it where `u64` timestamps were stored before. The standard library doesn't provide this functionality because it isn't something you can do reliably on all platforms. The idea is that we do our best and then fall back gracefully. This is a big change, because Servo was using `u64` timestamps all over the place some as raw values taken from `time::precise_time_ns()` and some as relative offsets from the "navigation start," which is a concept similar to DOM's `timeOrigin` (but not exactly the same). It's very difficult to fix this situation without fixing it everywhere as the `Instant` concept is supposed to be opaque. The good thing is that this change clears up all ambiguity when passing times as a `time::Duration` is unit agnostic and a `CrossProcessInstant` represents an absolute moment in time. The `time` version of `Duration` is used because it can both be negative and is also serializable. Good things: - No need too pass around `time` and `time_precise` any longer. `CrossProcessInstant` is also precise and monotonic. - The distinction between a time that is unset or at `0` (at some kind of timer epoch) is now gone. There still a lot of work to do to clean up timing, but this is the first step. In general, I've tried to preserve existing behavior, even when not spec compliant, as much as possible. I plan to submit followup PRs fixing some of the issues I've noticed. Signed-off-by: Martin Robinson <mrobinson@igalia.com>

* Remove use of unstable box syntax.Simon Sapin2017-10-161-1/+1
| | | | | | | | | | | | | | | | | | | | http://www.robohornet.org gives a score of 101.36 on master, and 102.68 with this PR. The latter is slightly better, but probably within noise level. So it looks like this PR does not affect DOM performance. This is expected since `Box::new` is defined as: ```rust impl<T> Box<T> { #[inline(always)] pub fn new(x: T) -> Box<T> { box x } } ``` With inlining, it should compile to the same as box syntax.

* Convert various helper traits from &JSRef to JSRefCameron Zwarich2014-09-201-2/+2
| | | | | | | | | | | | | | | I converted them all with a few exceptions: - Methods that were used by trait objects, since trait objects don't work with `self` methods. - Methods that take an &'b JSRef<'a, T> and return an &'b. In reality, many (all?) could return an &'a instead, but this isn't allowed by the Deref trait. - Methods that internally rely on the same issue with Deref. - I left out the traits involved in layout entirely, even though not all of their methods suffer from one of the above problems. There will probably be solutions to all of these problems in the future.

* First steps of &JSRef -> JSRef conversionCameron Zwarich2014-09-191-2/+2
| | | | | | | | | Replace &JSRef with JSRef in the bulk of the generated code. This will remove a level of indirection throughout all DOM code. This patch doesn't change methods implemented on JSRef<T> to take `self` rather than `&self`, and it leaves a few other uses of &JSRef, but those changes can be made incrementally.
