Generate a sorted, compressed series of ranges in a match table for
character classes, and use a binary search to find the matches.
This is about a 3-4x speedup for character class match performance. :^)
These fonts are currently used by Browser in some cases. This patch adds
glyphs for the codepoints
ÄÖÜßäöü„“‚‘…
which appear very frequently on German webpages, and fixes the alignment
of '*'.
Since we expose these strings to web content via LengthStyleValue,
let's not have non-standard brackets in there to confuse anyone trying
to parse these values. :^)
We now set the realm (twice) on every console input. This can probably
be avoided if we use two executing contexts one for the website the
other for the console.
This achieves a similar behavior but is not really nice and not really
spec like.
This meant that if some program threw an uncaught exception VM still
had unwind_until set. This caused any further programs to not execute
correctly.
This will be fixed more thoroughly once we use Completions in the AST.
Fixes#10323
For this we store the global environment in which we can do a lookup
for the references variable. This is probably not entirely as the spec
would specify as we would need a running executing context at all times
you do things with references.
Fixes#10281
This patch adds the "has a rendering opportunity" concept from the spec
to BrowsingContext and uses it to filter out contexts that are unable
to render right now when doing the event loop's rendering updates.
Note that we actually consider all contexts to have a rendering
opportunity at all times right now. Coming up with reasons to avoid
rendering is left as a FIXME. :^)
DOM::Document has some special lifetime rules to support the DOM
lifetime semantics expected on the web. Any DOM node will keep its
document alive as well, even after the document's ref-count has reached
zero. This is achieved by the Document::m_referencing_node_count
counter.
Because of this mechanism, we can't VERIFY(m_ref_count) in TreeNode
where T may be a DOM::Document.
This will be used by LibWeb to squirrel away the stack while performing
a microtask checkpoint in some cases. VM will simply consider saved
execution context stacks as GC roots as well.
We now invoke DOM timer callbacks via HTML tasks. This brings callback
sequencing closer to the spec, although there are still many
imperfections in this area.
This change is another minor step towards removing `AK::String` from
the Kernel. Instead of dynamically allocating the storage_name we can
instead allocate it via a KString in the factory for each device, and
then push the device name down into the StorageDevice base class.
We don't have a way of doing `AK::String::formatted(..)` with a KString
at the moment, so cleaning that up will be left for a later day.
Previously there was a mix of returning plain strings and returning
explicit string views using `operator ""sv`. This change switches them
all to standardized on `operator ""sv` as it avoids a call to strlen.

A zero-initialized mbstate_t struct has to be a valid initial state, so
we can just zero-initialize it whenever we need to reset.
Having a helper function for resetting the struct might imply that you
can add additional setup operations afterwards, which is not the case.
Each TLS record has a limited max size, we should respect that and split
the packets.
Fixes RecordOverflow errors when a packet larger than 18432 bytes is
sent over.
