When setting an element attribute to the value it already had, we don't
need to update style or invalidate anything that depends on the DOM
version counter.
This was a source of much pointless busywork.
You can now build with STYLE_INVALIDATION_DEBUG and get a debug stream
of reasons why style invalidations are happening and where.
I've rewritten this code many times, so instead of throwing it away once
again, I figured we should at least have it behind a flag.
Instead of switching on the PropertyID and doing a boatload of
comparisons, we reorder the PropertyID enum so that all inherited
properties are in two contiguous ranges (one for shorthands,
one for longhands).
This replaces the switch statement with two simple range checks.
Note that the property order change is observable via
window.getComputedStyle(), but the order of those properties is
implementation defined anyway.
Removes a 1.5% item from the profile when loading https://hemnet.se/
It would be nice if we could somehow move this work to the GPU, but even
with some basic local optimization (mostly coalescing bounds checks and
inlining pixel data access), this knocks a 13% item down to 9% in a
profile of loading https://vercel.com/
When accessed on the root/document element, the following properties are
derived from the viewport, not layout-dependent metrics:
- scrollLeft
- scrollTop
- scrollWidth
- scrollHeight
We now avoid synchronous layout in such cases. This was causing some
unnecessary layout work when loading https://vercel.com/
Before this change, we were cascading custom properties for each layer,
and then replacing any previously cascaded properties for the element
with only the set from this latest layer.
The patch fixes the issue by making each pass of the custom property
cascade add to the same set, and then finally assigning that set of
properties to the element.
Looking at the spec it doesn't seem like there's a chance for a service
worker client to be an environment but not an environment settings
object. In the case that that changes in the implementation, we can
move it.
This API is a relic from the time when it was important for objects to
have easy access to the Window, and to know it was the global object.
We now have more spec-related concepts like relevant_global_object and
current_global_object to pull the Window out of thin air.
This adds a storage tab which contains just a cookie viewer for now. In
the future, storage like Local Storage and Indexed DB can be added here
as well.
In this patch, the cookie table is read-only.
Cookies are typically deleted by setting their expiry time to an ancient
time stamp (i.e. this is how WebDriver is required to delete cookies).
Previously, we would update the cookie in the cookie jar, which would
mark the cookie as dirty. We would then purge expired cookies from the
jar's transient storage, which removed the cookie from the dirty list.
If the cookie was also in the persisted storage, it would never become
expired there as it was no longer in the dirty list when the timer for
synchronization fired.
Now, we don't remove any cookies from the transient dirty list when we
purge expired cookies. We hold onto the dirty cookie until sync time,
where we now update the cookie in the persisted storage *before* we
delete expired cookies.
It's getting a bit unwieldy to maintain as an inlined string. Move it to
its own file so it can be edited with syntax highlighting and other IDE
features.
This header held a bunch of utility functions shared across several code
generators. The only user of any of these utilities now is the public
suffix generator. Move the one used function to that generator, and
remove the common header.
This change adds green and red pass/fail emoji indicators to an in-tree
test — to make it easier to manually scan through the test results and
quickly see which cases are passing, and which are failing.
This change makes the aria-relevant content attribute the ariaRelevant
IDL/DOM attribute get reflected — which makes the Ladybird behavior
interoperable with the implemented behavior in other existing engines.
Otherwise, without this change, Ladybird fails the relevant test case in
https://wpt.fyi/results/html/dom/aria-attribute-reflection.html — which
other existing engines all pass.
Before this change, we were only checking for actual glyph containment
in a font if unicode ranges were specified. However that is not
sufficient for emoji support, where we want to continue searching for
a font until one containing emojis is found.
This change updates `ExecuteScript::execute_script()` and
`ExecuteScript::execute_script()` to bring their behavior in line with
each other and the current specification text.
Instances of the variable `timeout` have also been renamed to
`timeout_ms`, for clarity.
I didn't want to add another set of boilerplatey tree-walking methods,
so here's a general-purpose one. :^)
`for_each_effective_rule()` walks the tree of effective style rules, and
runs the callback on each one, in either pre- or postorder. The
previous `for_each_effective_style/keyframes_rule()` methods of
`CSSStyleSheet` are then reimplemented in terms of
`for_each_effective_rule()`, and we can get rid of their equivalents
elsewhere.
Depending on usage, `@layer` has two forms, with two different CSSOM
types. One simply lists layer names and the other defines a layer with
its contained rules.
