The JS::VM now owns the one Bytecode::Interpreter. We no longer have
multiple bytecode interpreters, and there is no concept of a "current"
bytecode interpreter.
If you ask for VM::bytecode_interpreter_if_exists(), it will return null
if we're not running the program in "bytecode enabled" mode.
If you ask for VM::bytecode_interpreter(), it will return a bytecode
interpreter in all modes. This is used for situations where even the AST
interpreter switches to bytecode mode (generators, etc.)
This was meant to be a temporary unit testuntil we could run test-js
in bytecode mode. This has been possible for a long time now, so let's
remove the unnecessary extra program.
This encoder is very naive as it only output SOF0 images and uses
pre-defined Huffman tables.
There is also a small bug with quantization which make using it
over-degrade the quality.
It's a little bit of a battle to fit all of the media controls in the
available width of the media element. We currently cram everything on
one horizontal line. We've made adjustments to be able to fit it all,
but the controls (in particular the media timeline) are rather squished.
This paints the timeline above the other media controls now. This
provides much more granular control over the playback position when
scrubbing, and makes it much more likely for the timeline to render at
all.
For example, on https://xboygeniusx.bandcamp.com/album/the-record, a
song with a duration of 03:52 would actually complete in 03:33 on my
machine. This issue only affects Ladybird on Lagom; on Serenity, we
already take the entire 03:52 to play the song.
This fixes the issue when size of abspos items is considered to be
resolvable without performing layout which is not correct in the
scenarious when top/right/bottom/left properties are not auto.
This implements the ability to drag the timeline and volume buttons on
UA-rendered media controls. The two behave a bit differently:
Volume is updated as the user drags the volume button. This isn't a very
expensive operation, so updating in real-time and hearing the volume
change feels nice.
The current time, on the other hand, is not committed until the user
releases the mouse button. Performing a seek every time we get a mouse-
move event is pretty laggy, especially for video. However, we still want
to render updates on the timeline itself (so the position of the button
and the timestamp update as you drag). To do so, we internally pause the
media and override the timestamp provided to the layout node.
In the future, we may be able to seek video periodically to provide some
visual feedback. For example, we can seek after every N seconds of
scrubbing, or when the user pauses scrubbing for a while.
It's currently possible to seek to the total sample count of an audio
loader. We must limit seeking to one less than that count.
This mistake was duplicated in both AudioCodecPluginSerenity/Ladybird,
so the computation was moved to a helper in the base AudioCodecPlugin.
The `report_time_in_ms` and `speed_update_time_in_ms` variables
weren't previously being respected. This was causing the progress
display to update too frequently, making it difficult to read.
The intent of the spec is that the output of console.dir is interactable
within the console. Our Printer implementation currently just prints the
provided object as a string, and doesn't check the provided `options`
argument. But having console.dir defined prevents exceptions from being
thrown on real websites.
This change adds the TTL value of the inbound packet to the output of
the userland ping program, bringing it more in line with other common
ping utilities. It also adds the (optional) -t option to configure the
TTL of the outgoing packet if desired.
Previously, touch would exit immediately if there was an error
changing file permissions. We now print an error to stderr and
continue when an error occurs.
Instead of a custom struct, use an AK::Variant for flex-basis.
A flex-basis is either `content` or a CSS size value, so we don't need
anything custom for that.
By using a CSS size, we also avoid having to convert in and out of size
in various places, simplifying the code.
This finally gets rid of the "Unsupported main size for flex-basis"
debug spam. :^)
Return error when input svg is not valid and SVGSVGElement is not
present in the tree instead of doing svg_root nullptr dereference.

When the default audio device changes on the host, it's convenient to
automatically switch to that device rather than needing to reload the
page to update.
To ensure actual PS2 code is not tied to the i8042 code, we make them
separated in the following ways:
- PS2KeyboardDevice and PS2MouseDevice classes are no longer inheriting
from the IRQHandler class. Instead we have specific IRQHandler derived
class for the i8042 controller implementation, which is used to ensure
that we don't end up mixing PS2 code with low-level interrupt handling
functionality. In the future this means that we could add a driver for
other PS2 controllers that might have only one interrupt handler but
multiple PS2 devices are attached, therefore, making it easier to put
the right propagation flow from the controller driver all the way to
the HID core code.
- A simple abstraction layer is added between the PS2 command set which
devices could use and the actual implementation low-level commands.
This means that the code in PS2MouseDevice and PS2KeyboardDevice
classes is no longer tied to i8042 implementation-specific commands,
so now these objects could send PS2 commands to their PS2 controller
and get a PS2Response which abstracts the given response too.
The HIDController class is removed and instead adding SerialIOController
class. The HIDController class was a mistake - there's no such thing in
real hardware as host controller only for human interface devices
(VirtIO PCI input controller being the exception here, but it could be
technically treated as serial IO controller too).
Instead, we simply add a new abstraction layer - the SerialIO "bus",
which will hold all the code that is related to serial communications
with other devices. A PS2 controller is simply a serial IO controller,
and the Intel 8042 Controller is simply a specific implementation of a
PS2 controller.
`FileSystem::absolute_path()` does `stat` the file, this commit runs
all `absolute_path` calls before touching the veil to make sure this
works as intended.
GCC's build fails in `libisl`'s configure step if `CC` is set to
Homebrew Clang with the message "Link Time Optimisation is not
supported". This is likely due to the fact that it tries to use ranlib
from Xcode, which is not compatible with the newer LLVM version's
bitcode format.
The toolchain build runs after `pick_host_compiler` is called, which
selects Homebrew Clang if the installed Xcode version is too old. We
need to unset `CC` and `CXX` for the toolchain build to sidestep the
issue.
