It appears that QEMU on macOS doesn't have the VirtIO GPU variants that
support VGA functionality. Those variants are not especially important
to us, because we don't use any kind of VGA functionality in our kernel
anyway.
Therefore, for macOS, we could decide to use virtio-gpu-gl-pci and
virtio-gpu-pci devices instead.
Required by code that brand checks native constructors.
For example, Wistia brand checks XMLHttpRequest by doing:
```
XMLHttpRequest.prototype.constructor.toString()
```
It then checks if it matches either one of:
```
function XMLHttpRequest() { [native code] }
```
```
[object XMLHttpRequestConstructor]
```
If neither matches, it disables HLS playback and prints:
"The XMLHttpRequest constructor has been tampered with. Because this
affects CORS/Range XHR requests, HLS playback has been disabled.
To enable HLS playback and other important features, please remove code
that changes the definition of window.XMLHttpRequest."
We hit this path due to not giving generated constructors a name, as
we would provide `function () { [native code] }`.
This patch parses enough of GPOS tables to be able to support the
kerning information embedded in Inter.
Since that specific font only applies positioning offsets to the first
glyph in each pair, I was able to get away with not changing our API.
Once we start adding support for more sophisticated positioning, we'll
need to be able to communicate more than a simple "kerning offset" to
the clients of this code.
Currently, the WebAssemblyObject implements a visitor to keep its static
objects alive. This custom attribute will be used to hook the generated
namespace object's visitor to one that we define in non-generated code.
Interfaces with a LegacyNamespace extended attribute should have their
constructors defined on the namespace identified by the LegacyNamespace
attribute value.
This is used by WebAssembly IDL files. For now, we mostly use this for
error messages and cache keys (to ensure compatibility with existing
code as WebAssembly is ported to IDL).
For example, consider the attribute:
interface Element {
[PutForwards=value] readonly attribute DOMTokenList classList;
}
When `classList` is set, we should instead set the attribute `value` on
the `classList` attribute of the Element interface.
Don't try to reserve capacity for a variadic arguments list unless we
actually have enough arguments to fill it with anything. Otherwise we
may overflow to an extremely large size if, e.g., the argument count
is 0 and the start of the variadic arguments is index 1.
We can always read the basic format information (sample rate, bit depth,
etc.), but we will also print artist, album, and title if available in
the metadata.
Similar to POSIX read, the basic read and write functions of AK::Stream
do not have a lower limit of how much data they read or write (apart
from "none at all").
Rename the functions to "read some [data]" and "write some [data]" (with
"data" being omitted, since everything here is reading and writing data)
to make them sufficiently distinct from the functions that ensure to
use the entire buffer (which should be the go-to function for most
usages).
No functional changes, just a lot of new FIXMEs.
Before, some loader plugins implemented their own buffering (FLAC&MP3),
some didn't require any (WAV), and some didn't buffer at all (QOA). This
meant that in practice, while you could load arbitrary amounts of
samples from some loader plugins, you couldn't do that with some others.
Also, it was ill-defined how many samples you would actually get back
from a get_more_samples call.
This commit fixes that by introducing a layer of abstraction between the
loader and its plugins (because that's the whole point of having the
extra class!). The plugins now only implement a load_chunks() function,
which is much simpler to implement and allows plugins to play fast and
loose with what they actually return. Basically, they can return many
chunks of samples, where one chunk is simply a convenient block of
samples to load. In fact, some loaders such as FLAC and QOA have
separate internal functions for loading exactly one chunk. The loaders
*should* load as many chunks as necessary for the sample count to be
reached or surpassed (the latter simplifies loading loops in the
implementations, since you don't need to know how large your next chunk
is going to be; a problem for e.g. FLAC). If a plugin has no problems
returning data of arbitrary size (currently WAV), it can return a single
chunk that exactly (or roughly) matches the requested sample count. If a
plugin is at the stream end, it can also return less samples than was
requested! The loader can handle all of these cases and may call into
load_chunk multiple times. If the plugin returns an empty chunk list (or
only empty chunks; again, they can play fast and loose), the loader
takes that as a stream end signal. Otherwise, the loader will always
return exactly as many samples as the user requested. Buffering is
handled by the loader, allowing any underlying plugin to deal with any
weird sample count requirement the user throws at it (looking at you,
SoundPlayer!).
This (not accidentally!) makes QOA work in SoundPlayer.
headless-browser currently uses its own PageClient to load web pages
in-process. Due to this, it also needs to set up a whole bunch of other
objects needed to run LibWeb, e.g. image decoders, request servers, etc.
This changes headless-browser to instead implement a WebView to launch
WebContent out-of-process. This implementation is almost entirely empty,
but can be filled in as-needed. For example, we may want to print
JavaScript console messages.
At the moment, all it can do is read all image formats that LibGfx can
read and save to any image format that LibGfx can write (currently bmp,
png, qoi).
Currently, it drops all image metadata (including color profiles).
Over time, this could learn tricks like keeping color profiles,
converting an image to a different color profile, cropping out a part of
an image, and so on.
"image" was an alias for "qemu-image".
I want to add an `image` userland utility, which clashes with that
shortname.
So remove the existing "image" target. It was just an alias for
"qemu-image".
If you use serenity.sh to build, nothing changes. This only affects you
if you run ninja manually -- you now have to say `ninja qemu-image` to
build the disk image.
Commit: 2c84466ad8 ("Kernel/Storage: Introduce new boot device
addressing modes") changed the way we pass the boot device parameter.
That commit missed updating boot parameter in the run.sh script for NVMe
boot devices.
We should be able to run this locally, as long as ENABLE_LAGOM_LADYBIRD
is true, or if building ladybird from the ladybird source directory.
This removes a special case from the Lagom CI yml file.
