Previously, VirtualFileSystem::resolve_path() could return a non-null
RefPtr<Custody>* out_parent even if the function errored because the
path has been veiled.
If code relies on recieving the parent custody even if the path is
veiled, it should just call resolve_path_without_veil and do the veil
validation manually. This is because it could be that the parent is
unveiled but the child isn't or the other way round.
I noticed after upgrading my machine that the QEMU is no longer building
due to GCC enabling `-fcf-protection` by default, even for targets that
don't support it.
The included patch came from the QEMU development list, but hasn't be
included in any patch releases at the time of writing.

Until QEMU patches, lets fix it on our end by patching before we build.
This also switches to checking out a specific commit instead of just the
master HEAD, as the port linter requires a hash (which is imo pointless
in this case), and we can't provide a stable hash for the master branch
HEAD.
This reverts commit 3a184f7841.
This broke a number of test262 tests under "TypedArrayConstructors".
The issue is that the CanonicalNumericIndexString AO should not fail
for inputs like "1.1", despite them not being integral indices.
The difference should be between m_utf8_iterator and the
the new position, if m_prev_utf8_iterator is used one fewer
source position is popped than required.
This issue was not apparent on most pages since restore_to
used for tokens such <!doctype> that are normally
followed by a newline that resets the column to zero,
but it can be seen on pages with minified HTML.
Putting everything in the global scope will lead to mayhem and failing
tests with an actually correct implementation of scoping :^)
Also adds in a tiny debug log of the exception, otherwise we'd be
staring at failing tests with no info on what failed.
Now we emit CreateVariable and SetVariable with the appropriate
initialization/environment modes, much closer to the spec.
This makes a whole lot of things like let/const variables, function
and variable hoisting and some other things work :^)
Instead of crashing on the spot, return a descriptive error that will
eventually continue its days as a javascript "InternalError" exception.
This should make random crashes with BC less likely.
This patch makes check_identifier_name_for_assignment_validity()
take a FlyString instead of a StringView. We then exploit this by
passing FlyString in more places via flystring_value().
This gives a ~1% speedup when parsing the largest Discord JS file.
When parsing identifiers, we ultimately want to sink the token string
into a FlyString anyway, and since Token may have a FlyString already
inside it, this allows us to bypass the costly FlyString(StringView).
This gives a ~3% speedup when parsing the largest Discord JS file.
Everyone who calls this already has a FlyString, so we were doing *way*
more work by pessimizing it to a StringView.
This gives a ~2% speedup when parsing the largest Discord JS file.
If the current character under the lexer cursor is ASCII, we don't need
to create a Utf8View to consume a full code point.
This gives a ~3% speedup when parsing the largest Discord JS file.
The vast majority of objects do not, and are unlikely to ever need
indexed property storage. By delaying the creation of the backing
store of IndexedProperties we reduce the memory used by each object
and reduce allocation and deallocation by somewhere between 20 and
30%
When performing GetValue on a primitive type we do not need to perform
the ToObject conversion as it will resolve to a property on the
prototype object.
To avoid this we skip the initial ToObject conversion on the base value
as it only serves to get the primitive's boxed prototype. We further
specialize on PrimitiveString in order to get efficient behaviour
behaviour for the direct properties.
Depending on the tests anywhere from 20 to 60%, with significant loop
overhead.
The spec version of canonical_numeric_index_string is absurdly complex,
and ends up converting from a string to a number, and then back again
which is both slow and also requires a few allocations and a string
compare.
Instead lets use the logic we already have as that is much more
efficient.
This improves performance of all non-numeric property names.
Previously we required there to be a focused widget so it would have
been able to opt out. In case the isn't a focused widget there is no way
for it to opt out anyways, so let's allow CommandPalette to work in this
case :^)
This stops all GML files from appeared under the "Changes not staged
for commit" section of the commit message comment due to the changed
last-modified timestamp of the file.
Specifically:
* Properties must precede sub-object declarations.
* There shouldn't be any newlines in-between properties.
* There should be a newline in-between each sub-object.
* Object declarations must include the curly braces.
* There should be a newline between the properties of an object and
it's sub-objects.
getClientRects supposed to return a list of bounding DOMRect
for each box fragment of Element's layout, but most elements have
only one box fragment, so implementing it with getBoundingClientRect
is useful.
