Before this change, every CSS @supports rule would keep the containing
JS realm alive via a JS::Handle. This led to a GC reference cycle and
the whole realm leaked.
Since we only need the realm at construction time, we can take it as a
parameter instead, and stop storing it.
...and use HeapFunction instead of SafeFunction for task steps.
Since there is only one EventLoop per process, it lives as a global
handle in the VM custom data.
This makes it much easier to reason about lifetimes of tasks, task
steps, and random stuff captured by them.
Part of this issue was fixed in 89877b3f40
but that only addressed the first layer of deferred_invoke, ignoring the
second one (which would cause a race if a request was sent to a host
immediately following a timeout event from the same host).
Fixes#23840.
This allows you to click on a <img> that has an ismap attribute, and
will result in the navigation URL having the coordinates appended as a
query to the URL.
It's a little bit confusing and awkward that we have `url` _and_
`url_string` here, but let's just fix the typo so that we correctly pass
through the URL with the given suffix (if any).
Currently, nothing is actually passing through this suffix - so it
doesn't fix anything yet, but it becomes relevant in the next commit.
This is often used on login forms, for example, to toggle the visibility
of a password. The site will change the <input> element's type to "text"
to allow the password to show.
...in the generic region decoding procedure (not yet in the generic
refinement region procedure). Not yet for EXTTEMPLATE though.
I haven't seen these being used in the wild, but:
* I want to optimize this code some, and it's probably good if it
is feature complete (and well-tested) before being optimized
* Other PDF engines implement support for this
* The Pattern/Halftone feature (which we don't yet implement either,
but which I'd like to implement because see previous two bullets)
calls the generic region decoding procedure with custom adaptive
template pixels
After some uptime the total_time_scheduled can get too big for accurate
float subtraction.
It's better to do the subtraction in u64 and use float only for the
division later on.
The intialization of Definition::value allocates a string that we were
holding a view into. Store the result as a String to keep it alive; its
only usage is passing it to GenericLexer in another function.
No need to force an allocation. This makes a future patch a bit simpler,
where we will have the encoding as a String. With this patch, we won't
have to convert it to a ByteString.
All string types currently have to invoke this function as:
stream.write_until_depleted("foo"sv.bytes());
This isn't very ergonomic, but more importantly, this overload will
allow String/ByteString instances to be written in this manner once
e.g. `ByteString::view() &&` is deleted.
Rather than making a copy of the held string, this returns a reference
so that expressions like the following:
do_something(json.as_string().view());
are not disallowed once `ByteString::view() &&` is deleted.
clang doesn't make all `Base::visit_edges()` calls CXXMemberCallExprs
This would lead to false positives like in HeapFunction,
where the matcher would fail to match and report a warning.
Also previously the matcher would succeed
if the visited class is missing the call to `Base::visit_edges()`
but an included class has a correct method.
The new matcher checks the current class for `visit_edges`-overrides
and matches all `visit_edges`-memberExprs inside,
checking those for starting with `Base::`.
This seems to get rid of the false positives
and should be more correct detecting missing calls.
When building, clang would throw errors about dangling references.
Extracting `template_args` to a variable before the loop and
indexing into that seems to fix the errors.
This patch implements the File API spec's supplemental steps for
document's "unloading document cleanup steps" so that we now remove blob
URLs associated with the document's relevant settings object when the
document is being unloaded.
Fixes two realm leaks when running our test suite.
f66d33423b was not sufficient to ensure
document destruction when a child navigable is destroyed. This is
because a navigable was remove from the set of all navigables too early
which led to `Navigable::navigable_with_active_document()` being unable
to find a navigable that is still in the process of destruction.
This change solves that by making all steps of a navigable destruction
to happen in afterAllDestruction callback.
Unfortunately, writing a test to verify document destruction is
challenging because no events are emitted to indicate that it has
happened.
