BCP 47 will be the single source of truth for known calendar and number
system keywords, and their aliases (e.g. "gregory" is an alias for
"gregorian"). Move the generation of available keywords to where we
parse the BCP 47 data, so that hard-coded aliases may be removed from
other generators.
We have a fair amount of hard-coded keywords / aliases that can now be
replaced with real data from BCP 47. As a result, the also changes the
awkward way we were previously generating keys. Before, we were more or
less generating keywords as a CSV list of keys, e.g. for the "nu" key,
we'd generate "latn,arab,grek" (ordered by locale preference). Then at
runtime, we'd split on the comma. We now just generate spans of keywords
directly.
This package was originally meant to be included in CLDR version 40, but
was missed in their release scripts. This has been resolved:
https://unicode-org.atlassian.net/browse/CLDR-15158
Unfortunately, the CLDR was re-released with the same version number. So
to bust the build's CLDR cache, change the "version" used to detect that
we need to redownload the CLDR.
Parse JSON floating point literals properly,
No longer throwing a SyntaxError when the decimal portion
of the number exceeds the capacity of u32.
Added tests to AK/TestJSON and LibJS/builtins/JSON/JSON.parse
The ECMA verbiage for modulus is the mathematical definition implemented
by fmod, so let's just use that rather than trying to reimplement all
the edge cases.
The same expression is not allowed to contain both the
logical && and || operators, and the coalescing ?? operator.
This patch changes how "forbidden" tokens are handled, using a
finite set instead of an Vector. This supports much more efficient
merging of the forbidden tokens when propagating forward, and
allowing the return of forbidden tokens to parent contexts.
If we're waiting for the client (typically Browser) to respond to a
synchronous IPC message from our side (e.g window.alert()) and the
client disconnects instead, just exit peacefully.
Ultimately a WebContent process lives to serve its client. When the
client dies, there is no need for WebContent anymore.
gethostbyname() and gethostbyaddr() now set h_errno (per spec) and try
to recover and return (with an error) instead of choking in VERIFY()
whenever an I/O or protocol error occurs in the communication with
LookupServer.
As noted, this is not entirely right, since we are using the computed
font's metrics instead of the initial font's metrics, but we do not
have a good way to obtain the latter.
We already supported "<input id=id><label for=id>".
This patch implements the other labeling mode, where the first labelable
descendant of the <label> element becomes the labeled control.
If we find a timer that needs to be fired immediately, we can stop
looking through the remaining timers.
This significantly reduces time spent in get_next_timer_expiration()
on ACID3. Of course, with a better data structure, we could reduce
time spent further. I've left a FIXME about that.
Pages such as https://html5test.com are testing all sorts of weird,
incomplete, and wrong HTML but can be useful or at least interesting for
development - let's try to avoid crashing the process.
This is needed to access the 'adjusted current node' in the 'Markup
declaration open state'. We don't want to create a full parser for
something like syntax highlighting, so it's optional (null) by default.
ACID3 test page throws exception about document.write. Let's at least
get rid of it by defining these stubs.
I added document.writeln too because it is similar.
Problem:
- `memset` is used to initialize data instead of using default
initialization.
Solution:
- Default initialize all member variables.
- Eliminate use of `memset` in favor of C++ braced initialization.
Problem:
- The getters and setters duplicate code for conversions.
- Getters are returning `const StringView` rather than non-`const`.
Solution:
- Factor out common code to helper functions.
- Return `StringView` as non-`const`.
We shouldn't let copy/move ctors or assignments be instantiated if the
assignee type does not have a copy/move constructor (even if they're not
used anywhere).
If we try to <link> a stylesheet that was already cached, we'll get a
synchronous resource_did_load() callback. Because of this, it's
necessary to set up the document load event delayer *before* calling
set_resource(), as otherwise we'd be stuck without a load event forever.

This ensures that the layout information is current, even when the
scroll request happens immediately upon page load.
This fixes an issue where reloading ACID2 wouldn't scroll down to the
"#top" anchor point.
