We were translating the pattern [\⪾-\⫀] to [\\u2abe-\\u2ac0], which
is a very different pattern; as a code unit converted to the \uhhh
format has no meaning when escaped, this commit makes us simply skip
escaping it when translating the pattern.
These are required for porting over Document from DeprecatedString to
String. We unfortunately can't port this completely over yet as
ParentNode is included by the Element IDL interface, which has not yet
been ported over from DeprecatedString.
This prevents the menu and toolbar action state getting out of sync,
which could happen previously. The menu item also now shows the
appropriate icon rather than a checkbox.
The Kernel/API directory in general shouldn't include userspace code,
but structure definitions that both are shared between the Kernel and
userspace.
All users of the ioctl API obviously use LibC so LibC is the most common
and shared library for the affected programs.
The Kernel/API directory in general shouldn't include userspace code,
but structure definitions that both are shared between the Kernel and
userspace.
LibC is the most appropriate place for these methods as they're already
included in the sys/sysmacros.h file to create a set of convenient
macros for these methods.

This update includes a new set of code point properties, Indic Conjunct
Break. These may have the values Consonant, Linker, or Extend. These are
used in text segmentation to prevent breaking on some extended grapheme
cluster sequences.
If a navigable has been destroyed during a navigation process, we
should early return from it. The introduced checks are not in
the spec because, as explained in
https://github.com/whatwg/html/issues/9690 the spec is not written
with such a level of detail.
Replaces direct "apply the history step" calls with new functions from
the spec:
- "update for navigable creation/destruction"
- "apply the push/replace history step"
- "apply the reload history step"
Fixes a crash in `get_session_history_entries()` that happens when
it attempts to find entries for a navigable that hasn't been fully
initialized and therefore doesn't have a nested history entry yet.
Callback running on the session history queue should capture necessary
pointers by value instead of reference, because navigate_to_a_fragment
stack will have been destroyed by the time it will be executed.
for_each_cell_among_possible_pointers() was taking HashTable by value
instead of by const reference for no reason.
The copying was soaking up ~4% of CPU time while loading https://x.com/
Previously, we used `on_load_finish` to determine when the text test
was completed. This method did not allow testing of async functions
because there was no way to indicate that the runner should wait for
the async call to end.
This change introduces a function in the `internals` object that is
intended to be called when the text test execution is completed. The
text test runner will now ignore `on_load_finish` which means a test
will timeout if this new function is never called.
`test(f)` function in `include.js` has been modified to automatically
terminate a test once `load` event is fired on `window`.
new `asyncTest(f)` function has been introduces. `f` receives function
that will terminate a test as a first argument.
Every test is expected to call either `test()` or `asyncTest()` to
complete. If not, it will remain hanging until a timeout occurs.
This fixes the sizing of the arrow icons displayed to the left of
parent sections on a table of contents on Wikipedia articles, which
are sized using the equation `calc(max(0.75em, 12px))`. Now, the icon
will not expand past the edges of the box they are within, avoiding
clipping the edges of the arrows.
We shouldn't be putting generated pseudo elements inside elements that
can't have children in the first place.
This patch fixes two issues:
- We stop generating pseudo elements for layout nodes that can't have
children anyway.
- We mark Layout::BreakNode as not being able to have children.
Instead of running a big switch statement on the opcode when checking
how long an instruction is, we now simply store that in a member
variable at construction time for instant access.
This yields a 10.2% speed-up on Kraken/ai-astar :^)
These apply to any elements that have some kind of open/closed state.
The spec suggests `<details>`, `<dialog>`, and `<select>`, so that's
what I've supported here. Only `<details>` is fleshed out right now,
but once the others are, these pseudo-classes should work
automatically. :^)
The CSS Selectors-4 spec suggests that `:open` and `:closed` should
apply to `<select>` elements, so let's add a way of storing and
exposing that state. We don't yet actually generate any layout for
`<select>` elements, so they will always report that they are closed.
The spec requires that details elements be assigned a shadow tree with
two slots. The first slot is assigned the first summary child element of
the details element. The second slot is assigned all other children.
Most events on a slottable are composed, meaning they propagate from the
slottable and through its shadow tree before bubbling up to the parent
of the slottable.
This implements looking up a slottable's assigned slot, and a slot's
list of assigned slottables. For the latter, only unflattened lookups
are implemented so far.
This implements automatic slottable assignment by way of hooking into
the element attribute change steps. When the `name` attribute of a slot
or the `slot` attribute of a slottable changes, assignment is performed.
This implements manual slottable assignment by way of HTMLSlotElement's
`assign` API. This includes all of the slottable-related AOs needed to
perform the assignment.
A slottable is either a DOM element or a DOM text node. They may be
assigned to slots (HTMLSlotElement) either automatically or manually.
Automatic assignment occurs by matching a slot's `name` attribute to
a slottable's `slot` attribute. Manual assignment occurs by using the
slot's (not yet implemented) `assign` API.
This commit does not perform the above assignments. It just sets up the
slottable concept via IDL and hooks the slottable mixin into the element
and text nodes.
This is similar to the run activation behavior in that elements may
define these steps themselves. HTMLSlotElement is one such element. The
existing (ad-hoc) Element::attribute_changed() method is not sufficient
there as the steps require knowledge of the attribute's old value and
its namespace, which this extension provides.
Unlike the run activation behavior, we store these steps in a list. An
element may end up defining multiple attribute change steps. For example
all DOM elements must define steps to handle the "slot" attribute, and
HTMLSlotElement must define steps to handle the "name" attribute.
The spec now has a "toggle task tracker" to coalesce rapid changes to
this attribute. It also now has an explicit ToggleEvent to encapsulate
the old and new state of the element.
This further handles the attribute being added/removed using a override
of Element::attribute_changed(), rather than being the only element to
instead override Element::set/remove__attribute().
Each ref test now links to its reference page with a link tag, in the
same format as WPT:
`<link rel="match" href="reference-page.html" />`
The reference pages have all been moved into a separate `reference/` dir
so that we can just treat every file in `ref/` as a test. There's no
filter to only look at .html files, because we also have a .svg file in
there, and there may be other formats we want to use too. But it's not
too hard to add one if we need it.
This attempts to load the URL of the first `<link rel="match" href=""/>`
it finds. If that tag is missing, we load an error page to make sure
the ref-test fails. (And to provide some feedback if someone looks at
the screenshot somehow.) Wrong URLs will instead end up loading the
default 404 error page.
Previously, when there were more rows or columns than the BoardWidget
could contain, nothing was displayed. The BoardWidget minimum size is
now set whenever the number of rows or columns changes.
This change also ensures that the redo stack is cleared when a move is
made, so that it isn't possible to redo a previous move after having
made a new one.
Call them from the helpers for strings. We'll have other object classes
soon that need to serialize ByteBuffers, so let's take advantage of the
encoding scheme we are already using for Strings.
We skip serializing any of the internal state of the Regex<ECMA262>
object, because that state is all computable from the input pattern
and flags. If it turns out that this is really, really slow, we can add
some optimizations to serialize more of the regex parse result.
If we serialize a string followed by some other object, the deserialize
helper would just happily keep appending bytes to the string until the
end of the serialization buffer. Avoid doing that by checking the string
length for figuring out when the string actually ends.
Instead of caching start-of-line offsets, we now cache byte offsets
at regular intervals. This fixes an issue where we had terrible
performance on large minified JS, since that often means one very,
VERY long line (with no line endings to cache).
My machine was spending ~35ms per stack frame when throwing errors
on some heavy minified websites, and after this patch, we now spend
<1ms per stack frame.
