Client messages, which are always requests, are dispatched to Actor
instances one at a time via Actor::handle_message. Each request must be
paired with exactly one reply from the same actor the request was sent
to, where a reply is a message with no type (if a message from the
server has a type, it’s a notification, not a reply).
Failing to reply to a request will almost always permanently break that
actor, because either the client gets stuck waiting for a reply, or the
client receives the reply for a subsequent request as if it was the
reply for the current request. If an actor fails to reply to a request,
we want the dispatcher (ActorRegistry::handle_message) to send an error
of type `unrecognizedPacketType`, to keep the conversation for that
actor in sync. Since replies come in all shapes and sizes, we want to
allow Actor types to send replies without having to return them to the
dispatcher.
This patch adds a wrapper type around a client stream that guarantees
request/reply invariants. It allows the dispatcher to check if a valid
reply was sent, and guarantees that if the actor tries to send a reply,
it’s actually a valid reply (see ClientRequest::is_valid_reply). It does
not currently guarantee anything about messages sent via the TcpStream
released via ClientRequest::try_clone_stream or the return value of
ClientRequest::reply. We also send `unrecognizedPacketType`,
`missingParameter`, `badParameterType`, and `noSuchActor` messages per
the
[protocol](https://firefox-source-docs.mozilla.org/devtools/backend/protocol.html#error-packets)
[docs](https://firefox-source-docs.mozilla.org/devtools/backend/protocol.html#packets).

The specification moved around lately with how it defines its reports
and report bodies. They became dictionaries, but are currently missing
some fields [1].
Most tests won't be passing yet, since the `Reporting-Endpoints` header
isn't used yet. In fact, the specification leaves it up to the browser
to figure out when to run this task [2]. I am not sure if there some
background scheduling we can do here.
Confirmed with content-security-policy/reporting-api/
report-to-directive-allowed-in-meta.https.sub.html that the callback is
invoked. The test doesn't pass, since
the `describe_scripted_caller` is empty for HTML elements. Thus the
`source_file` is empty, whereas it should be equivalent to the current
document URL.

I'm getting an unused import warning when I use Rust-Analyzer in VS
Code. I also fixed the license text which I think had gotten changed by
accident.
Testing: I built and ran the example with `cargo build --example
winit_minimal` in the `components/servo` folder. There were some unused
code warnings but they don't show up in Rust-Analyzer's output and I
suspect they are used by other code.

The will-navigate message tells the devtools client to expect a
navigation for a browsing context. This makes the network monitor clear
any previous entries and show the requests for the new page that is
loaded. In order to support this correctly, we need to send the
navigation notification from the constellation instead of the script
thread, otherwise we silently ignore navigations triggered by the
browser URL bar.

Dealing with both path and builder makes code complicated and this is
backend internal specific anyway (we often do conversions between the
two just so we get specific functionality). Now I joined both into
single abstractions `Path`, that has all what one needs and let raqote
backend deal with path/pathbuilder coversions.
Motivation: Simplification and in Vello there is only
[BezPath](https://docs.rs/kurbo/0.11.2/kurbo/struct.BezPath.html) so we
use it as both path and pathbuilder.
Reviewable per commit.

[RootCause]:Tochdown executes normally, but touchup fails during hittest
and does not send a touchup event to the script, causing the script to
save an incorrect number of active_touch_points. The application
receives an incorrect event.touches.length, causing a logic error and
preventing the carousel from sliding.
[Solution]:
When hit test on compositor fails, we also need to send the
EmbedderToConstellationMessage::ForwardInputEvent message to
constellation. In the script's handle_touch_event, if it exits early, we
also need to update active_touch_points.

This pull request introduces changes to the storage subsystem to:
- Isolate sessionStorage per top-level browsing context (WebViewId), in
addition to origin.
- Copy sessionStorage when creating a new auxiliary browsing context
without

These changes bring Servo closer to spec compliance, matching expected
browser

I introduced snapshot in #36119 to pack raw bytes and metadata together,
now we take the next step and require for user to always specify what
kind of byte data they want when calling `as_bytes` or `to_vec`
(basically joining transform and data). There are also valid usages when
one might require just one property of bytes (textures can generally
handle both RGBA and BGRA). There are also valid usages of using just
raw bytes (when cropping). This PR tries to make such usages more
obvious.
This will make it easier to fix stuff around 2d canvas (we do not want
to assume any bytes properties in abstraction).
Testing: Code is covered by WPT tests.

This creates a new method in shared/compositing/lib to generate image
keys that are send over the webview. This does not immediately return
the keys but goes over the constellation to receive the keys from the
IOCompositor. To make this more efficient, we now cache the keys in
image_cache in a simple FIFO order. The old blocking method stays intact
for now but got renamed to make the blocking clear.
The blocking calls that are left are in:
- `components/canvas/canvas_data.rs`
- `components/script/dom/htmlmediaelement.rs`
Testing: WPT tests should cover this as this doesn't change any
functionality.

Previously, our Servo-specific spatial tree scroll offsets were opposite
to
that of WebRender and also the web platform. This is due to the fact,
likely, that `winit` wheel directionality is also flipped. This change
has both the Servo spatial tree and the API take offsets that are
consistent with the web.
Any possible changes to the meaning of wheel directionality will be
handled in a followup change.
This is a breaking change to the Servo API.

This change:
- Adds a new type of LayoutDamage that signifies that a box needs its
children recollected, because one or more of them need to be rebuilt.
- During restyle damage propagation, propagate this new damage upward in
the tree. Then box tree construction should be able to preserve any
still-valid box tree nodes from box slots.
- During BlockLevelBox job finalization, if a box slot is valid and
there is not LayoutDamage to the element, use the old box slot,
ensuring that its fragment cache is invalidated.

by existing WPT tests.

This PR adds backtrace demangling to background hang monitor, thereby
removing a `TODO` in the component source.
The required `rustc-demangle` crate dependency is gated behind
`#[cfg(feature = "sampler")]` as it is my understanding that the
surrounding code is only called when `sampler` is enabled.
Testing: testing was done manually - I suppose a substring match for a
known demangled string could be used for adding a proper test case, and
checking `RUSTFLAGS` to discern whether `v0` demangling should be
expected? Open to suggestions. Manual testing was done by printf
debugging (not part of the PR):

In layout, some parts of the code were still using parallel iterators
from Rayon even when single-thread layout was activated. This change
modifies those parts to use non-parallel iterators when
`LayoutContext::use_rayon` is not active.
Testing: It's very hard to make an automated test for this, but I've
manually
verified this by building with tracing and observing that layout runs
only on
a single thread now when loading https://servo.org.

Only Firefox has this quirk, Chrome and Safari don't. So it's simpler to
just remove it.

1. Rename `GetWindowSize` to `GetWindowRect`
2. Return the WindowRect in device pixels correctly. Previously, it
returns `(0, 0, ScreenWidth, ScreenHeight)` which is a static value.
3. Add `fn window_rect` to `WindowPortsMethods`. Implement it for both
Headless Window and Headed Window.
Testing: Tested manually with powershell script. Result is now dynamic
and reflects the truth.
Fixes: Task 1 & 2 of https://github.com/servo/servo/issues/37804

We were also enforcing that in limited-quirks mode, but no other browser
does that. In fact, Blink and WebKit don't have this quirk at all, so we
should consider removing it too, but for now restrict it to quirks mode
like Firefox.
Testing: adding new tests

Follow the HTML specification and reject the pending image decode
promises
on any current request mutation.

18)
https://html.spec.whatwg.org/multipage/#dom-img-decode (step 3)
Fulfill and reject image decode promises by queueing
a global tasks on the DOM manipulation task source.

While this makes our implementation deviate slightly from the
specification, this clarifies an invariant with the code itself. This
helps to resolve some confusion as seen in
https://github.com/servo/servo/issues/37695#issuecomment-3013823350.
Testing: This should not change behavior and is thus covered by existing
WPT tests.

Currently, HTMLImageElement uses as an image source
(ImageBitmapSource, CanvasImageSource, TexImageSource)
in various canvas2D/WebGL operations, and there is a small
inconsistency in how we get the image data of the 'img' element:
usability checking and retrieving the image data from the image cache.
To simplify and avoid state inconsistency between the window's image
cache and the 'img' element, let's retrieve the image data (as a raster)
from the HTMLImageElement itself.
Testing: No expected changes in testing results, except the
'drawimage_svg_image_with_foreign_object_does_not_taint.html'
which is 'false' passed because drawing of the non supported vector
image
is silently skip instead of throwing the 'InvalidState' exception
anymore.

This implementation is quite confusing as it makes it harder to tell
that we are just looking for the case that `Contents` contains
`NonReplacedContents`.
Testing: This shouldn't have any functional change, so is covered by
existing tests.

While raqote does already passes this test, but small line is still

this.

1. Remove the unnecessary new thread which use GetWindowRect command and
blocks for 500ms. Previously this is necessary because constellation
forward "resize" to embedder, and WebDriver wait for a constant
sufficient time to `GetWindowRect` in the new thread. This caused long
delay because there are many subtests and SetWindowRect is called
between each.
2. Remove `resize_timeout`
3. Return current dimension instead of 0 from embedder when it fails to
resize.
4. Do resizing as long as one of width/height is `Some`, according to
spec.
Testing: All Conformance test with new passing cases.
