`Core::Stream::File` shouldn't hold any utility methods that are
unrelated to constructing a `Core::Stream`, so let's just replace the
existing `Core::File::exists` with the nicer looking implementation.
Note that js_rope_string() has been folded into this, the old name was
misleading - it would not always create a rope string, only if both
sides are not empty strings. Use a three-argument create() overload
instead.
Gfx::Color is always 4 bytes (it's just a wrapper over u32) it's less
work just to pass the color directly.
This also updates IPCCompiler to prevent from generating
Gfx::Color const &, which makes replacement easier.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
The runtime environment of the WASM REPL does not have time zone
information; the file system is virtual (does not have /etc/localtime),
and the TZ environment variable is not set. This causes LibTimeZone to
always fall back to UTC.
Instead, we can get the time zone from the user's browser before we
enter this limited environment. The REPL website will pass the time zone
into the WASM REPL.
Without this, we were in a weird state where LibTimeZone believed it had
TZDB data, but that data wasn't actually available to it. This caused
functions like JS::get_named_time_zone_offset_nanoseconds() to trip an
assertion when entering "new Date();" into the REPL.
This now prepares all the needed (fallible) components before actually
constructing a LoaderPlugin object, so we are no longer filling them in
at an arbitrary later point in time.
These are used by esvu, and it is sad that we don't have macOS binaries
availble for consumption by esvu users. Add a matrix job to handle this
separately from the test262 results.
This was forgotten to be added in the LibWeb GC conversion.
This caused some brand checks to fail in skribbl.io's JavaScript and
thus caused unexpected exceptions.
The Demuxer class was changed to return errors for more functions so
that all of the underlying reading can be done lazily. Other than that,
the demuxer interface is unchanged, and only the underlying reader was
modified.
The MatroskaDocument class is no more, and MatroskaReader's getter
functions replace it. Every MatroskaReader getter beyond the Segment
element's position is parsed lazily from the file as needed. This means
that all getter functions can return DecoderErrors which must be
handled by callers.
As new demuxers are added, this will get quite full of files, so it'll
be good to have a separate folder for these.
To avoid too many chained namespaces, the Containers subdirectory is
not also a namespace, but the Matroska folder is for the sake of
separating the multiple classes for parsed information entering the
Video namespace.
This adds command line flags for WebDriver to pass its IPC socket path
(if running on Serenity) or its FD passing socket (if running elsewhere)
for the headless-browser to connect to.
Hand-picking the smallest index type that fits a particular generated
array started with commit 3ad159537e. This
was to reduce the size of the generated library.
Since then, the number of types using UniqueStorage has grown a ton,
creating a long list of types for which index types are manually picked.
When a new UCD/CLDR/TZDB is released, and the current index type no
longer fits the generated data, we fail to generate. Tracking down which
index caused the failure is a pretty annoying process.
Instead, we can just use size_t while in the generators themselves, then
automatically pick the size needed for the generated code.
When an IPC message returns a single value, we generate a class with a
constructor that is something like:
class MessageResponse {
MessageResponse(SingleReturnType value)
: m_value(move(value))
{
}
};
If that IPC message wants to return a value that SingleReturnType is
constructible from, you have to wrap that return call with braces:
return { value_that_could_construct_single_return_type };
That isn't really an issue except for when we want to mix TRY semantics
with the return type. If SingleReturnType is constructible from an Error
type (i.e. something similar to ErrorOr), the following doesn't work:
TRY(fallible_function());
Because MessageResponse would not be constructible from Error. Instead,
we must do some workaround with a custom TRY macro, as in 31bb792.
This patch generates a constructor that makes TRY usable as-is without
any custom macros. We perform a very similar trick in ThrowCompletionOr
inside LibJS. This constructor will allow you to create MessageResponse
from any type that SingleReturnType is constructible from.
Previously each emoji had its own symbol in the library which was then
referred to by another symbol. This caused thousands of avoidable data
relocations at load time.
This saves about 122kB RAM for each process which uses LibUnicode.
Previously the s_decomposition_mappings variable would refer to other
data in s_decomposition_mappings_data. This would cause thousands of
avoidable relocations at load time.
This saves about 128kB RAM for each process which uses LibUnicode.
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
The class is virtual and has one subclass, SubsampledYUVFrame, which
is used by the VP9 decoder to return a single frame. The
output_to_bitmap(Bitmap&) function can be used to set pixels on an
existing bitmap of the correct size to the RGB values that
should be displayed. The to_bitmap() function will allocate a new bitmap
and fill it using output_to_bitmap.
This new class also implements bilinear scaling of the subsampled U and
V planes so that subsampled videos' colors will appear smoother.
We currently have two build-time parsers for the UCD's emoji-test.txt
file. To prepare for future changes, this removes the Bash parser and
moves its functionality to the newer C++ parser.
There were some notable changes to the CLDR JSON format and data in this
release.
The patterns for a date at a specific time, i.e. "{date} at {time}", now
appear under the "atTime" attribute of the "dateTimeFormats" object.
Locale specific changes that affected test-js:
All locales:
* In many patterns, the code points U+00A0 (NO-BREAK SPACE) and U+202F
(NARROW NO-BREAK SPACE) are now used in place of an ASCII space. For
example, before the "dayPeriod" fields AM and PM.
* Separators such as U+2013 (EN DASH) are now surrounded by U+2009 (THIN
SPACE) in place of an ASCII space character.
Locale "en":
* Narrow localizations of time formats are even more narrow. For
example, the abbreviation "wk." for "week" is now just "wk".
Locale "ar":
* The code point U+060C (ARABIC COMMA) is now used in place of an ASCII
comma.
* The code point U+200F (RIGHT-TO-LEFT MARK) now appears at the
beginning of many localizations.
* When the "latn" numbering system is used for currency formatting, the
currency symbol more consistently is placed at the end of the pattern.
Locale "he":
* The "many" plural rules category has been removed.
Locales "zh" and "es-419":
* Several display-name localizations were changed.
