Fix caching before the console is opened and stop sending messages
prematurely.
Fix line numbers not showing in console messages because of a missing
`rename_all`.
Remove `getCachedMessages` in favour of sending a list of messages as a
reply to the `watchResources` for `console-message`/`error-message` in
the watcher.
Remove `startListeners` and `stopListeners`. These are legacy methods of
watching properties before the watcher actor. It is preferred to enable
properties in `supported_resources` in the watcher than to use these
messages.
Remove `clearMessagesCache`, only `clearMessagesCacheAsync` seems to be
used now. Add a reply to `clearMessagesCacheAsync`.
Simplify a bit the structs for console messages and prefer serde's
annotations to manual serialization. Merge `handle_console_message` and
`handle_page_error`, and improve the usability of `ConsoleResource`.
Fix some fields in console messages. We are missing `source_id` for now.
This will be easier to add after better support for source actors. We
are also missing stack traces.

A warning has been showing up every time the DevTools client was
connected in Firefox Browser Console. Now not only the watcher can watch
resources, the root actor can too. Firefox was complaining about
[`extensions-backgroundscript-status`](https://searchfox.org/firefox-main/source/devtools/server/actors/resources/extensions-backgroundscript-status.js).
We don't have extensions running in the background, but even if we set
it to false, the warning persists. So instead this patch adds
boilerplate to "handle" this watch request.

Replace `RefCell` with `AtomicRefCell` for structs implementing Actor,
making them `Sync`.
Consolidate `register` and `register_later` into a single function,
removing the need to wait for a loop before accessing newly created
actors.
Now `ActorRegsitry` has improved locking. Instead of locking the entire
struct, each member can be locked separately. Additionally, since `find`
now returns `Arc`, we can `find` and `register` multiple actors
depending on each other, since the lock is only needed for the operation
and we can keep the reference after that.

Remove `find_mut` from `ActorRegistry`. Force that all actors must be
immutable after being inserted in the registry, only allowing changes
through internal mutability.
First step in refactoring `ActorRegistry` to make it more reliable,
easier to use and less error prone.
Depends on #41741. `NetworkEventActor` was more complicated to refactor

Now `NetworkEventActor`'s methods take a non mutable reference to self
(`add_request`, `add_response` and `add_security_info`). This actor now
has three different `RefCells` inside (`request`, `response` and
`security`), which group pieces of data that are updated separately via
the public methods.
For the actor functionality itself, it now follows Firefox more closely.
In the `resource-available` message it only sends the `*_available`
fields (i.e. `response_headers_available`), deferring the actual data to
the `get*` messages (i.e `getResponseHeaders`). There were also a few
slight changes I noticed along the way that I tried to fix.
Simplify some repeated logic calculating header sizes and listing
cookies.
`resource_updates` is updated to use `Serialize` structs instead of
manually adding values to a map. This is more in line with the rest of
the DevTools code and probably less prone to future errors.
Fix "Resource of network-event is missing a browsingContextID or
innerWindowId attribute" error that shows multiple times each time the
Network tab is open. Updated all messages to use the correct

Replace the previously hardcoded "name prefix" strings for actors with
[`type_name`](https://doc.rust-lang.org/std/any/fn.type_name.html).
Note that we aren't using the prefix directly as an unique identifier,
and `type_name` wouldn't be suitable for that. The suffix is an
incremental counter shared across all actors, so that alone is enough to
differentiate them.
The purpose of the prefix is to visually inspect the logs and see what
actors are involved. With this change the prefix will be slightly
different: "InspectorActor11" vs "inspector11", but that shouldn't
affect behaviour.
The eventual goal is to remove `new_name` and force the use of
`register/register_later` to create an actor. This is however a bit more
complicated, see #41768.
While I'd love to add `base_name` directly to the `Actor` trait, that
would unfortunately mean that it wouldn't be [dyn
compatible](https://doc.rust-lang.org/reference/items/traits.html#dyn-compatibility).
There are workarounds for this like separating the trait in two and
implementing it automatically, but I feel that would be too convoluted.
Testing: Manual testing, this patch shouldn't change behaviour.

The `ActorRegistry::shareable` field is a copy of the
`Arc<Mutex<ActorRegistry>>` in `DevtoolsInstance`. It seemed to only be
used for the timeline actor. That adds complexity to `ActorRegistry` for
only one actor (which we aren't even using at the moment, the entire
`timeline.rs` is marked as dead code), and it is possible to avoid it by
storing the `Arc<Mutex<..>>` copy directly on the timeline actor when it
is created.
The same goes for `start_stamp`, it is only used in the timeline and it
is ok to have it there instead. Since (if used) the timeline would have
to be created alongside the registry there wouldn't be a noticeable time
difference.
Rename the field in `DevtoolsInstance` from `actors` to `registry` for
consistency with (most) of the other code in the crate.

Inspector sub-actors (walker, highlighter and page-style) had an overly
complicated creation mechanism using `RefCell<Option<...>>` and
instantiating these actors afterwards. Since the client always asks for
the three actors and instantiating them isn't that expensive, we aren't
saving anything from delaying this, and it introduces unnecessary
complexity.
For `*Msg`, make inspector sub-actors follow the rest and implement
`ActorEncode` instead of manually creating the struct in
`handle_message`.
Note that this change doesn't fix the issue with navigation/reloading
breaking the inspector. I am planning to send a patch for that, but it
is cleaner to separate this refactor and merge it before.
Testing: Manually test that the inspector still works.

For all upcoming and already-processed deferred fetches, we now
implement a quota. We don't support policy headers yet to configure the
quota, hence we use the default quota. That's why we have some tests
failing again.
It involves computing which document to compute the quota for, as well
as computing total length of requests. Additionally, the DevTools
computation for headers now uses the same logic for headers as deferred
fetches.

incorrect or outdated messages, such as an error with `reflow`.
The only meaningful change I could find is that the performance actor is
now called "perf" instead of "performance". It is part of a set of
global actors that the root handles. I made it more explicit and moved
the global actor registration inside of the root actor, it makes more
sense to have it there.
Finally, I ordered the message handling alphabetically. The only changed
entry is `getRoot` because of the global actors.

Unify various `encodable` and `encode` methods from actors in an
`ActorEncode` trait, making it more consistent.
Add an `ActorRegistry::encode` method that finds an actor by name and
then returns its serialized version.
Add an `ActorMsg` struct to avoid creating repeated structs for simple
serializations.
There are two exceptions: `EncodableConsoleMessage` and `NodeInfo`.
These also have an `encode` method, but they are not actors, so
including them in this trait doesn't make much sense. Besides, they have
special requirements so it is better to keep them separate.

#38614 was reverted due to CI flakiness, but it also included several
improvements to the devtools tests. this patch relands those
improvements, described below.
we make three changes that speed up the devtools tests from 73 → 65 → 56
→ 51 seconds:
- we replace the hardcoded sleep(1) after starting servoshell with a
loop that waits until the devtools port is open (this also fixes
intermittent failures when servoshell starts too slowly, especially on
macOS)
- we start the internal web servers once, and reuse them across all
tests
- we run servoshell in headless mode (this is also required because most
CI runners have no GUI)
and we fix two bugs that cause very noisy but not very interesting error
messages:
- in the test code, we use a [context
manager](https://docs.python.org/3/reference/datamodel.html#context-managers)
to ensure the devtools client is disconnected unconditionally, even if
test methods or assert helper methods raise exceptions (this was causing
errors on all platforms)
- in the devtools server, we treat “connection reset” errors when
reading from the client like a normal EOF, rather than as a failure
(this was causing errors on Windows)
on self-hosted linux builds, there are still spurious error messages
like the following, but we can fix them later:
```
error: XDG_RUNTIME_DIR not set in the environment.
libEGL warning: egl: failed to create dri2 screen
```

their coverage
