This is a vestige of the transition from 2015 to 2018 edition Rust.
`async` was added as a keyword in 2018 edition Rust, so `cargo fix`
changed the variable name here to `r#async`.
In the previous Promise.all way, we registered a promise for every
module script which means we will need to do many complex checkings like
"is this top level?" and it will make us much more difficult to understand
how the module script algorithm works.
In the new manual checking way, we will only register promises for top
level modules to notify its owner (e.g. the script element) to finish
the load. So, we can understand it much more easily and would be more
spec-aligned.
Also, I think the `Ready` and `FetchFailed` status are quite confusing
and we actually don't need them so they're removed in this patch. Then,
we will always go to `Finished` instead.
It would basically be following steps:
+-----------------+
| Failed to fetch | ----------+
+--------------+ +----------+ / +-----------------+ |
| Fetch module | ----> | Fetching | ---+ v
+--------------+ +----------+ \ +---------+ +---------------------+
| Fetched | | Advance to Finished |
+---------+ +---------------------+
| ^
v |
+-------------------+ |
| Fetch descendants | ----- if no descendants
+-------------------+
|
V
+----------------------+
| Fetching Descendants |
+----------------------+
In `Advance to Finished`, it means that module script is about to finished so it will
1. Notify all of its `ready` and `not finished` parents to finish
2. Link (instantiate) the module
3. Resolve its promise to notify owner(s) to finish
I misunderstood the test case when I worked on #23545. That test case is
actually not related to dynamic import; instead, the reason why it
crashes is, `currentScript` should be updated to `null`.
Update content-security-policy.
This allows hubs.mozilla.org to load instead of panicking due to unimplemented CSP features.

- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix#24702
- [x] These changes do not require tests because we never enabled the CSP testsuite
This needs a lot more hooks before it'll actually be a good
implementation, but for a start it can help get some feedback on if this
is the right way to go about it.
Part of servo/servo#4577
- this conforms to follow-hyperlinks spec step 13
- this conforms to window-open spec step 14.3
- replace uses of `referrer_url` with `referrer`
- in Request class, change "no-referrer" to ""
- set websocket fetch referrer to "no-referrer"
Do not unwrap empty unminified_js_dir in HTMLScriptElement.unminify_js.
Calling unwrap caused a panic when a directory could not be created.

The following IDLs have the src/href attributes typed as a DOMString
while in the spec the attribute has been updated to be a USVString:
- HTMLIFrameElement
- HTMLImageElement
- HTMLInputElement
- HTMLLinkElement
- HTMLMediaElement
- HTMLScriptElement
refactoring with ResourceFetchMetadata
implemented deprecated window.timing functionality
created ResourceTimingListener trait
fixed w3c links in navigation timing
updated include.ini to run resource timing tests on ci
I moved away from the `Window` struct all the logic to handle task
sources, into a new struct called `TaskManager`. In a happy world, I'd
be able to just have there two functions, of the types:
```rust
fn task_source<T: TaskSource>(&self, name: TaskSourceName) -> Box<T>
fn task_source_with_canceller<T: TaskSource>(&self, name: TaskSourceName)
-> (Box<T>, TaskSourceCanceller)
```
And not so much duplicated code. However, because TaskSource can't be a
trait object (because it has generic type parameters), that's not
possible. Instead, I decided to reduce duplicated logic through macros.
For reasons[1], I have to pass both the name of the function with
canceller and the name of the function without, as I'm not able to
concatenate them in the macro itself. I could probably use
`concat_idents` to create both types already defined and reduce the
amount of arguments by one, but that macro is nightly only. At the same
time, not being able to declare macros inside `impl` forces me to pass
`self` as an argument.
All this makes this solution more verbose than it would be ideally. It
does reduce duplication, but it doesn't reduce the size of the file.
