This is a bit of a chonkier commit as it results in both:
clean_up_after_running_callback and prepare_to_run_callback being
changed to accept a realm instead of an environment settings object,
which has a bunch of fallout, particuarly for IDL abstract operations.
Instead of a settings object. This matches updates to the HTML spec as
part of the shadow realm proposal, and begins the refactor of running
scripts on a realm instead of a settings environment object.
Some of the spec steps are slightly messy here (such as in
MainThreadVM.cpp) as this partially implements the ShadowRealm changes
but not other pieces which we have not implemented yet, such as
preparing to run a script also being based on a realm instead of an
environment. But this will be addressed in further commits.
In terms of the 'current principal realm' definition.
No functional impact, as we still need to implement current principal
realm once the surrounding infrastructure is in place. But it is one
less place which needs to be updated when that is all in place :^)
Aligning the name with the the PR implementing the javascript
shadow realm proposal into the web platform. This commit
simply performs the rename before implementing the behaviour
change.
The actual change to the behaviour of the AO is not implemented in this
commit to support 'synthetic' shadow realms as the surrounding
infrastructure is not in place yet.
Not all specs have a MR open to align with this proposed change to the
HTML standard. But in this case we can just apply the same mechanical
change everywhere.
At some point we must have broken the ability of running XHTML test
cases, so the whitespace expectation changes have not been rebaselined
for this test case.
This is an attempt to bring the size of Parser.cpp down. No code
changes, just moves and some explicit template instantiations now that
we're using them from a different file.
With a8077f79cc Selection object is no
longer aware of selection state inside text controls (<textarea> and
<input>), so this change makes them responsible for dispatching
`selectionchange` if their selection state was changed.
This change switches the Meta/import-wpt-test.py script to using the
standard html.parser module rather than BeautifulSoup.
Otherwise, without this change, when a contributor first tries to run
the script, if they don’t have BeautifulSoup installed, it will fail.
Note that this patch also includes an unrelated small change that
switches to using os.path.normpath — rather than Path.absolute() — to
“normalize” the destination names of the downloaded test files.
This is not in the spec, but I did see a null pointer dereference here
while browsing the web, and it seems completely harmless for this
function to skip over navigables without an active document.
This is just a wrapper to easily construct an Array from a span. This
avoids creating a Vector of values that are possiby Objects. One such
case is in ArrayIteratorPrototype::next.
This is not safe from GC. Unfortunately we cannot add a test to capture
the issue, as the allocation which may trigger GC is internal and not
observable from JS.
