We were miscalculating the length of the buffer in pointer-sized chunks,
which is what the conservative root scan cares about.
This could cause some values to be prematurely garbage-collected.
This was preventing https://ubereats.com/ from fully loading, because
they are attempting to overwrite setItem. They seem to be trying to add
error logging to setItem if it throws, as all they do is add a
try/catch block that emits an error log to their monitoring service if
it throws.
However, because Storage is a legacy platform object with a named
property setter (setItem), it will call setItem with the stringified
version of the function. This is actually expected as per the spec,
Firefox (Gecko) and Epiphany (WebKit) does this too, but Chromium does
not as it actually overwrites the function with the new function and
does not store the stringified function.
The problem is that we had the LegacyOverrideBuiltIns flag accidentally
set, so it would return the stored string instead of the built-in
function (hence the name), then it would try and call it and throw a
"not a function" error. This prevented their JS from going any further.
This fix allows their UI to fully load and be fully interactive, though
it is quite slow at the moment!
This change removes the append_without_space, append_with_space,
prepend_without_space, and prepend_with_space functions from DOM::Node.
All those methods were added with the initial “Implement Accessible Name
and Description Calculation” commit in da5c918 and were only used in the
code related to accessible-name computation. But subsequent changes to
that code have removed all the calls to those functions — so now they’re
all completely unused.
This change ensures that when the aria-labelledby attribute is used, the
expected text from the element referenced in the aria-labelledby value
appears in the computed accessible name. Otherwise, without this change,
the expected text doesn’t appear in the computed accessible name.
This change fixes handling for substep ii of the “F. Name From Content”
step at https://w3c.github.io/accname/#step2F in the “Accessible Name
and Description Computation” spec — to correctly include any ::before
and ::after pseudo-element content in the computation of accessible
names. Otherwise, without this change, accessible names unexpectedly
don’t include that pseudo-element content.
This change implements the https://w3c.github.io/accname/#comp_append
step in the “Accessible Name and Description Computation” spec — so that
when an accessible name is computed from multiple sources in a document
subtree, the parts of the computed text are joined together with spaces.
Otherwise without this change, in accessible names computed from
multiple sources in a document subtree, the parts of the computed text
are unexpectedly run together, with no spaces between the parts.
This is really just a type alias for NonnullGCPtr<T>, but it provides
a way to have non-owning non-visited NonnullGCPtr<T> without getting
yelled at by the Clang plugin for catching GC errors.
We were previously dumping the address of the cell pointer instead of
the address of the cell itself. This was causing mysterious orphans
in GC dumps, and it took me way too long to figure this out.
compute_inset() was incorrectly retrieving the containing block size
because containing_block() is unaware of grid areas that form a
containing block for grid items but do not exist in the layout tree.
With this change, we explicitly pass the containing block into
compute_inset(), allowing it to correctly provide the containing block
sizes for grid items.
Explicitly pass containing block width in
resolve_vertical_box_model_metrics() instead of doing containing block
box lookup.
This is a part of refactoring towards removing containing_block() usage
that will allow us introduce partial layout.
The following syntax is valid:
```js
e?.example / 1.2
```
Previously, the `/` would be treated as a unterminated regex literal,
because it was calling the regular `consume` instead of
`consume_and_allow_division`.
This is what is done when parsing IdentifierNames in
parse_secondary_expression when a period is encountered.
Allows us to parse clients-main-[hash].js on https://ubereats.com/
We now skip so many tests that the list of skipped tests exceeds the
height of my terminal. Let's skip logging these by default, as it is
too noisy to find actually relevant information.
We currently compile the Qt event loop files multiple times, for every
target which wants to use them. This patch moves these to LibWebView as
a central location to avoid this.
If available space is definite it should always match the size of the
containing block. Therefore, there is no need to do containing block
node lookup.
The inline capacity on ThreadEventQueue::Private::queued_events caused
us to reserve (and importantly, not initialize!) 2 KiB of stack memory
when entering ThreadEventQueue::process().
This was causing any leftover pointers to GC-allocated objects within
that memory range to keep those objects alive, even when all other
references were gone.
