When applied, corresponding interface object will not be exposed on the
global object, e.g. for the following IDL:
```
Exposed=(Window,Worker), LegacyNoInterfaceObject]
interface ANGLE_instanced_arrays {
};
```
executing `"ANGLE_instanced_arrays" in window` will return `false`.
PlatformObjects with named properties does not qualify as 'has own
property' just by virtue of a named property existing.
This fixes at least one WPT test, which is imported.
This change does replacement of ARIA roles that have newer synonyms.
There are a number of newer ARIA roles that are synonyms for older
roles. https://wpt.fyi/results/wai-aria/role/synonym-roles.html has a
number of subtests which expect that when retrieving the value of an
explicitly- specified role attribute, if the value is one of the older
role values, implementations must replace that with its newer synonym.
This commit enables warnings when using variable length arrays. For
disabling this warning locally use -Wno-vla, as it will work both across
Clang and GCC.
There are some special values for CSS::Selector::PseudoElement::Type
which are after `KnownPseudoElementCount` and therefore not present in
various arrays of pseudo elements, this leads to some errors, if a type
after `KnownPseudoElementCount` is used without checking first. This
adds explicit checks to all usages
Ensure becomes `m1` greater than `m2` even when smaller by more than
one `p`. Since the next operations on `m1` are modulus `p` we can add it
as many times as it's needed.
The official WPT runner supports a `<meta name=timeout content=long>`
tag to let tests opt-in to a longer timeout. Modify our harness to pass
that custom timeout to our runner, so that we don't incorrectly time
out if our default time is shorter than the requested one.
Some tests take longer than others, and so may want to set a custom
timeout so that they pass, without increasing the timeout for all other
tests. For example, this is done in WPT.
Add an `internals.setTestTimeout(milliseconds)` method that overrides
the test runner's default timeout for the currently-run test.
If we have a valid PNG header with geometry info etc, we should still
display it as *something*, even if the image data itself is missing or
corrupted.
This matches the behavior of other browsers, and is something that
Cloudflare Turnstile checks for.
To achieve this, we split the PNG decoder's initialization into two
steps: "everything except reading frame data" and "reading frame data".
If the latter step fails, we yield a transparent bitmap with the
geometry from the PNG's IHDR chunk.
This would fail with EINVAL earlier, due to an attempt to create a
zero-length Core::AnonymousBuffer.
We fix this by transferring the buffer length separately, and only
going down the AnonymousBuffer allocation path if the length is
non-zero.
When message encoding failed for some reason, we'd just swallow the
error without saying a word, and carry on without sending anything.
This led to some very confusing situations.
`WebIDL::invoke_callback()` now takes an `exception_behavior`
parameter, which can be set to `report` to report an exception before
returning. Setting `exception_behavior` to `rethrow` retains the
previous behavior.
This way we could be sure that context object won't be deallocated
before any of the objects that belong to it.
Having a context pointer is also going to be used in upcoming changes
to generate an INVALID_OPERATION error if an object does not belong to
the context it's being used in.
Make sure that `HashAlgorithmIdentifier` is passed through
`normalize_an_algorithm` to verify that the hash is valid and supported.
This is required by the spec, but we are not following it very strictly
in `normalize_an_algorithm` because it is pretty convoluted.
Fixes ~60 tests.
