(#36533)
This reverts commit 4c55104b36c7b858a117a6dd90a5dc21b74324d1.
This commit introduced an issue where messages from script to the
compositor no longer woke up the embedder. There is a larger issue
here, but this change exacerbated it.
Fixes #36528.

Because there used to be two traits exposing messages to the compositor,
there were two kinds of messages that could be sent:
1. In-process messages from the `Constellation`
2. Cross-process messages from other parts of Servo
Now these two types of messages can be unified into one type. With that
done the compositor can simply keep a single `IpcReceiver` for all
messages, instead of having to set up a route for the cross-process
messsages. This decreases overhead of cross proceses messages a bit, but
more importantly solves an issue where Servo would rely on the
compositor's cross-process message route after the `Constellation` had
called `ROUTER.shutdown()`.
This is part of #36442.
Testing: This is covered by existing WPT tests.

These two traits both exposed different parts of the compositing API,
but now that the compositor doesn't depend directly on `script` any
longer and the `script_traits` crate has been split into the
`constellation_traits` crate, this can be finally be cleaned up without
causing circular dependencies. In addition, some unit tests for the
`IOPCompositor`'s scroll node tree are also moved into
`compositing_traits` as well.
Testing: This just combines two crates, so no new tests are necessary.
Fixes: #35984.

This is the last big change necessary to create the
`constellation_traits` crate. This moves the data structure for messages
that originate from the `ScriptThread` and are sent to the
`Contellation` to `constellation_traits`, effectively splitting
`script_traits` in half. Before, `script_traits` was responsible for
exposing the API of both the `ScriptThread` and the `Constellation` to
the rest of Servo.
- Data structures that are used by `ScriptToConstellationMsg` are moved
to `constellation_traits`. The dependency graph looks a bit like this:
`script_layout_interface` depends on `script_traits` depends on
`constellation_traits` depends on `embedder_traits`.
- Data structures that are used in the embedding layer
(`UntrustedNodeAddress`, `CompositorHitTestResult`, `TouchEventResult`
and `AnimationState`) are moved to embedder_traits, to avoid a
dependency cycle between `webrender_traits` and
`constellation_traits`.
- Types dealing with MessagePorts and serialization are moved to
`constellation_traits::message_port`.
Testing: This is covered by existing tests as it just moves types
around.

So far the memory reporter aggregates reports from all processes, and
runs the system reporter only in the main process. Instead it is
desirable to have per-process reports. We do so by:
- creating a ProcessReports struct that holds includes the pid in
addition to the reports themselves.
- running the system memory reporter also in content processes.
- updating the about:memory page to create one report per process, and
add useful information like the pid and the urls loaded in a given
process.

This introduces a process manager that holds for each process a
"lifeline": this is the receiving end of a ipc channel that is not used
to send anything, but only to monitor the process presence. We turn that
ipc receiver into a crossbeam one to integrate the monitoring into the
constellation run loop. The sender side is made part of the initial
"UnprivilegedContent" data structure sent to the new process, both for
content and for service worker processes.
When a process dies we currently wait() on it to let the OS do a clean
shutdown.

(#36312)
The `Constellation` previously held a `window_size` member, but this
assumes that all `WebView`s have the same size. This change removes that
assumption as well as making sure that all `WebView`s pass their size
and HiDIP scaling to the `Constellation` when they are created.
In addition
- `WindowSizeData` is renamed to `ViewportDetails`, as it was
holding more than just the size and it didn't necessarily correspond to
a "window." It's used for tracking viewport data, whether for an
`<iframe>` or the main `WebView` viewport.
- `ViewportDetails` is stored more consistently so that conceptually an
`<iframe>` can also have its own HiDPI scaling. This isn't something
we necessarily want, but it makes everything conceptually simpler.
The goal with this change is to work toward allowing per-`WebView` HiDPI
scaling and sizing. There are still some corresponding changes in the
compositor to make that happen, but they will in a subsequent change.
Testing: This is covered by existing tests. There should be no behavior
changes.
Fixes: This is part of #36232.

- Remove `EmbedderMethods::get_user_agent_string`. This is now part of
the `Preferences` data structure, which should allow it to be
per-`WebView` in the future.
- Remove `EmbedderMethods::get_version_string`. This was used to include
some data along with WebRender captures about the Servo version. This
isn't really necessary and it was done to replace code in the past
that output the WebRender version, so also isn't what the original
code did. I think we can just remove this entirely.
The idea with these changes is that `EmbedderMethods` can be removed
in a followup and the rest of the methods can be added to
`ServoDelegate`. These two methods are ones that cannot be added to a
delegate as they are used during `Servo` initialization.
Testing: There is currently no testing for libservo. These changes are
meant
as preparation for adding a suite of `WebView` unit tests.

This is a clean up after #36062 and #35985. It removes the script
channel for each pipeline from the compositor. Now all messages are sent
via the `Constellation` first, which will allow breaking the dependency
on script in the compositor.
In addition, scroll states are actually sent via the `Constellation`,
which was an oversight from #36062. Finally, a typo in a method name is
fixed.

This change creates a `constellation_traits` crate. Previously messages
to the `Constellation` were in the `compositing_traits` crate, which
came about organically. This change moves these to a new crate which
also contains data types that are used in both compositing/libservo and
script (ie types that cross the process boundary). The idea is similar
to `embedding_traits`, but this is meant for types not exposed to the
API.
This change allows deduplicating `UntrustedNodeAddress`, which
previously had two versions to avoid circular dependencies.

Simply how `ProgressiveWebMetrics` works:
1. Keep only a single struct instead of one in layout and one script
that both implement the `ProgressiveWebMetrics` trait. Since layout
and script are the same thread these can now just be a single
`ProgressiveWebMetrics` struct stored in script.
2. Have the compositor be responsible for informing the Constellation
(which informs the ScripThread) about paint metrics. This makes
communication flow one way and removes one dependency between the
compositor and script (of two).
3. All units tests are moved into the `metrics` crate itself since there
is only one struct there now.

(#35701)
This is one of the first big steps toward making the compositor work
per-WebView. It moves the collection of pipelines into the per-WebView
data structure in the compositor as well as the pending paint metrics.
This means that more messages need to carry information about the
WebView they apply to. Note that there are still a few places that we
need to map from `PipelineId` to `WebViewId`, so this also includes a
shared mapping which tracks this. The mapping can be removed once event
handling is fully per-WebView.

At some point in the past this message was only sent from the
`Constellation` to `script`, but nowadays this is sent from various
parts of servo to the `ScriptThread`, so this is a better name. In
particular, the current name makes it seeem like this message controls
the `Constellation`, which it does not.

Flatten and simplify Servo's preferences code. In addition, have both
preferences and options passed in as arguments to `Servo::new()` and
make sure not to use the globally set preferences in `servoshell` (as
much as possible now).
Instead of a complex procedural macro to generate preferences, just
expose a very simple derive macro that adds string based getters and
setters.
- All command-line parsing is moved to servoshell.
- There is no longer the concept of a missing preference.
- Preferences no longer have to be part of the resources bundle because
they now have reasonable default values.
- servoshell specific preferences are no longer part of the preferences
exposed by the Servo API.

Create two new data structures in the `script` crate to hold senders and
receiver:
- `ScriptThreadSenders`: holds all outgoing channels from the
`ScriptThread` including a channel to the `ScriptThread` itself. The
ultimate goal with this is to reduce duplication by giving a boxed
version of this this to `Window`s.
- `ScriptThradReceivers`: holds all incoming channels to the
`ScriptThread`. This isn't cloenable like the senders. This is used to
abstract away `recv()` and `try_recv()` methods used to make the
`ScriptThread` event loop easier to read.
In addition:
- The many duplicated `ScriptThread` self-senders for the `TaskManager`
have been removed and, in general, a lot of boilerplate is removed as
well.
- Visibilty of all methods affected by this change is changed to
`pub(crate)` in order to take advantage of dead code detection. Some
dead code produced from macros is removed.
- Some conversion code is refactord into implementations of the `From`
trait.
- The names of channels uses a standard "sender" and "receiver" naming
as well as trying to be descriptive of where they go in `ScriptThread`
as well as `InitialScriptState`

Before all timers were managed by the Constellation process, meaning
that they had to trigger IPC calls to be scheduled and fired. Currently,
timers are only used in the `ScriptThread`, so it makes sense that they
are per-process.
This change restores the timer thread functionality that existed before
avoided entirely. Completion is done using a callback that is sent to
the timer thread similarly to how fetch is done. This allows reusing the
existing task queue without making any new channels.
Fixes #15219.

Instead of exposing many different kinds of messages to the compositor
that are routed through the constellation, expose a single message type
which can be sent across IPC channels. In addition, this IPC channel and
the route to the crossbeam channel with the compositor is created along
with the `CompositorProxy`, simplifying what needs to be passed around
during pipeline initialization.
Previously, some image updates (from video) were sent over IPC with a
special serialization routine and some were sent via crossbeam channels
(canvas). Now all updates go over the IPC channel `IpcSharedMemory` is
used to avoid serialization penalties. This should improve performance
and reduce copies for video, but add a memory copy overhead for canvas.
This will improve in the future when canvas renders directly into a
texture.
All-in-all this is a simplification which opens the path toward having a
standard compositor API and reduces the number of duplicate messages and
proxying that had to happen in libservo.

This changes modifes the way that font data is sent over IPC channels.
Instead of serializing the data or sending it via IPC byte senders, font
data is copied into shared memory and a copy of the handle is sent over
the channel.
There is also the idea of sending the file handle of the on disk data of
system fonts. This could be implemented as a further followup once there
is an abstraction in `ipc-channel` over file handles.
To accomplish this, a `FontData` abstraction is added, which also allows
caching an in-memory shared `Arc<Vec<u8>>` version of the data (neeeded
by some APIs). This could also be a place for caching font tables in the
future.
Finally, the `FontCacheThread` is renamed to the `SystemFontService`
while the proxy for this is now named `SystemFontServiceProxy`.

For a long time, `gfx_traits` has held a lot of things unrelated to graphics
and also unrelated to the `gfx` crate (which is mostly about fonts).
This is a cleanup which does a few things:
1. Move non `gfx` crate things out of `gfx_traits`. This is important in
order to prevent dependency cycles with a different integration between
layout, script, and fonts.
2. Rename the `msg` crate to `base`. It didn't really contain anything
to do with messages and instead mostly holds ids, which are used
across many different crates in Servo. This new crate will hold the
*rare* data types that are widely used.
Details:
- All BackgroundHangMonitor-related things from base to a new
`background_hang_monitor_api` crate.
- Moved `TraversalDirection` to `script_traits`
- Moved `Epoch`-related things from `gfx_traits` to `base`.
- Moved `PrintTree` to base. This should be widely useful in Servo.
- Moved `WebrenderApi` from `base` to `webrender_traits` and renamed it
to `WebRenderFontApi`.

* script: Do not run layout in a thread
Instead of spawning a thread for layout that almost always runs
synchronously with script, simply run layout in the script thread.
This is a resurrection of #28708, taking just the bits that remove the
layout thread. It's a complex change and thus is just a first step
toward cleaning up the interface between script and layout. Messages are
still passed from script to layout via a `process()` method and script
proxies some messages to layout from other threads as well.
Big changes:
1. Layout is created in the script thread on Document load, thus every
live document is guaranteed to have a layout. This isn't completely
hidden in the interface, but we can safely `unwrap()` on a Document's
layout.
2. Layout configuration is abstracted away into a LayoutConfig struct
and the LayoutFactory is a struct passed around by the Constellation.
This is to avoid having to monomorphize the entire script thread
for each layout.
3. Instead of having the Constellation block on the layout thread to
figure out the current epoch and whether there are pending web fonts
loading, updates are sent synchronously to the Constellation when
rendering to a screenshot. This practically only used by the WPT.
A couple tests start to fail, which is probably inevitable since removing
the layout thread has introduced timing changes in "exit after load" and
screenshot behavior.
