Spec: https://html.spec.whatwg.org/multipage/#dom-textarea/input-setrangetext
In order to do this, we need to define the SelectionMode enum in WebIDL:
https://html.spec.whatwg.org/multipage/#selectionmode
Since the enum is used by HTMLTextAreaElement and HTMLInputElement, it
doesn't seem to make sense to define it in the WebIDL file for one or
other of those.
However, we also can't create a stand-alone SelectionMode.webidl file,
because the current binding-generation code won't generate a "pub mod
SelectionMode;" line in mod.rs unless SelectionMode.webidl contains
either an interface or a namespace. (This logic happens in
components/script/dom/bindings/codegen/Configuration.py:35, in the
Configuration.__init__ method.)
I thought about changing the binding-generation code, but that seems
difficult. So I settled for placing the enum inside
HTMLFormElement.webidl, as that seems like a "neutral" location. We
could equally settle for putting it under HTMLTextAreaElement or
HTMLInputElement, it probably doesn't really matter.
The setRangeText algorithm set the "dirty value flag" on the
input/textarea. I made some clean-ups related to this:
1. HTMLTextAreaElement called its dirty value flag "value_changed"; I
changed this to "value_dirty" to be consistent with the spec.
2. HTMLInputElement had a "value_changed" field and also a "value_dirty"
field, which were each used in slightly different places (and
sometimes in both places). I consolidated these into a single
"value_dirty" field, which was necessary in order to make some of the
tests pass.
TextControl::set_dom_range_text replaces part of the existing textinput
content with the replacement string (steps 9-10 of the algorithm). My
implementation changes the textinput's selection and then replaces the
selection. A downside of this approach is that we lose the original
selection state from before the call to setRangeText. Therefore, we have
to save the state into the original_selection_state variable so that we
can later pass it into TextControl::set_selection_range. This allows
TextControl::set_selection_range to correctly decide whether or not to
fire the select event.
An alternative approach would be to implement a method on TextInput
which allows a subtring of the content to be mutated, without touching
the current selection state. However, any such method would potentially
put the TextInput into an inconsistent state where the edit_point and/or
selection_origin is a TextPoint which doesn't exist in the content. It
would be up to the caller to subsequently make sure that the TextInput
gets put back into a valid state (which would actually happen, when
TextControl::set_selection_range is called).
I think TextInput's public API should not make it possible to put it
into an invalid state, as that would be a potential source of bugs.
That's why I didn't take this approach. (TextInput's public API does
currently make it possible to create an invalid state, but I'd like to
submit a follow-up patch to lock this down.)
Root sequence<any> params using CustomAutoRooter
<!-- Please describe your changes on the following line: -->
Attempt at https://github.com/servo/servo/issues/16678. At the moment this pulls an external [remove-handle-conv](https://github.com/Xanewok/rust-mozjs/tree/remove-handle-conv) branch for rust-mozjs (removing `FromJSValConvertible` implementation for `HandleValue` and adding one for `*mut JSObject`)
In short, this roots the `sequence<any>` and `sequence<object>` function arguments using `CustomAutoRooter` (introduced in https://github.com/servo/rust-mozjs/pull/382).
As per https://github.com/servo/servo/issues/16678#issuecomment-302224110 the underlying vector contains raw gc thing pointers instead of handles. To do that, this introduces new possible `isMember = "AutoRoot"` value in CodegenRust.py.
The rooted argument is passed to a function wrapped in a `CustomAutoRooterGuard` [RAII root guard](ed5e37a288/src/rust.rs (L586-L588)) (e.g. as `CustomAutoRooterGuard<Vec<JSVal>>`)
I felt quite out of my depth when trying to adapt CodegenRust.py code, so I'd appreciate any help with how can be done better/in a more clean manner.
Also the name `CustomAutoRooterGuard` is quite lengthy, so I'm also open to changing it (`AutoRoot`? `AutoRootGuard`?)

When a paint worklet thread takes too long, we would like to move on,
since we have a ~16ms budget for rendering @60fps. At the moment, there
is no provision in the paintworklet spec to signal such timeouts to the
developer. ajeffrey opened an [issue][1] for this, but it got punted to
v2 of the spec. Hence we are silently timing out unresponsive paint
scripts.
The timeout value is chosen to be 10ms by default, and can be overridden
by setting the `dom.worklet.timeout_ms` pref.
In the absence of such a timeout, the reftest in this commit would fail
by timing out the testrunner itself, since the paint script never
returns. From my discussions with ajeffrey, this should do until we spec
out a way to signal timeouts to the script developer.
Since we did not have a better way to trigger a timeout than a busy
waiting loop (which would hog one core of the test machine until the
timeout was reached), we decided to implement a test only blocking
sleep, available to the PaintWorkletGlobalScope. Since
`dom.worklet.enabled` enables worklets in general, we also decided to
have another pref `dom.worklet.blockingsleep.enabled`, which, in
addition to `dom.worklet.enabled`, would be required for the blocking
sleep to be available.
This fixes#17370.
[1]: https://github.com/w3c/css-houdini-drafts/issues/507
The selection API only applies to certain <input> types:
https://html.spec.whatwg.org/multipage/#do-not-apply
This commit ensures that we handle that correctly.
Some notes:
1. TextControl::set_dom_selection_direction now calls
set_selection_range(), which means that setting selectionDirection will
now fire a selection event, as it should per the spec.
2. There is a test for the firing of the select event in
tests/wpt/web-platform-tests/html/semantics/forms/textfieldselection/select-event.html,
however the test did not run due to this syntax error:
(pid:26017) "ERROR:script::dom::bindings::error: Error at http://web-platform.test:8000/html/semantics/forms/textfieldselection/select-event.html:50:11 missing = in const declaration"
This happens due to the us of the "for (const foo of ...)" construct.
Per https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of
this should actually work, so it's somewhat unsatisfying to have to
change the test.
4. If an <input>'s type is unset, it defaults to a text, and the
selection API applies. Also, if an <input>'s type is set to an
invalid value, it defaults to a text too. I've expanded the tests
to account for this second case.

Fix Const IDL value compilation errors in codegen
<!-- Please describe your changes on the following line: -->
I found that some const WebIDL values fail at rust compile time.
Example:
const long long TIMEOUT_IGNORED = -1;
```
906 | ConstantSpec { name: b"TIMEOUT_IGNORED\0", value: ConstantVal::DoubleVal(-1) }]
| ^^ expected f64, found integral variable
|
= note: expected type `f64`
found type `{integer}`
```
I added a explicit cast to to fix the problem in conversions that may fail to compile.

PerformanceObserverInit.buffered
Per #18108, add `buffered` flag in the `PerformanceObserverInit` dict.
Per W3C spec, when `buffered` is set, `PerformanceObserver.observe()` method adds the entries buffered in the `Performance` instance into the observer's entry buffer.
One step is the implementation of the [filter by name and type](https://w3c.github.io/performance-timeline/#filter-buffer-by-name-and-type) algorithm. Don't think that the sort operation is useful in this case, but the spec states that this algorithm is to be used.

We parse when assigning using the namespaces of the stylesheet. It isn't
clear if the spec says to do that (Firefox doesn't support the setter at
all, Chrome does, Safari doesn't); the spec issue is here:

Also fix ToCss implementation of AttrSelectorOperator to not pad with
spaces, to conform with CSSOM. This means we have to update some unit
tests that expect operators with spaces around them in attribute
selectors to roundtrip.
