Currently, Kernel::Graphics::FramebufferConsole is written assuming that
the underlying framebuffer memory exists in physically contiguous
memory. There are a bunch of framebuffer devices that would need to use
the components of FramebufferConsole (in particular access to the kernel
bitmap font rendering logic). To reduce code duplication, framebuffer
console has been split into two parts, the abstract
GenericFramebufferConsole class which does the rendering, and the
ContiguousFramebufferConsole class which contains all logic related to
managing the underling vm object.
Also, a new flush method has been added to the class, to support devices
that require an extra flush step to render.
Previously, whenever Editor::set_document() was called, we destroyed
the previous LanguageClient instance of the editor and created a new
one.
We now check if the language of the existing LanguageClient matches the
new document, and if so we do not create a new LanguageClient instance.
This fixes an issue where doing "goto definition" would crash
HackStudio. This was probably introduced in 44418cb351.
The crash occurred because when doing "goto definition", we called a
AK::Function callback from the LanguageClient, which internally called
Editor::set_document().
Editor::set_document() destroyed the existing LanguageClient, which
cased a VERIFY in Function::clear() to fail because we were trying to
destroy the AK::Function object while executing inside it.
This commit adds a loader for the FLAC audio codec, the Free Lossless
Audio codec by the Xiph.Org foundation. LibAudio will automatically
read and parse FLAC files, so users do not need to adjust.
This implementation is bare-bones and needs to be improved upon.
There are many bugs, verbatim subframes and any kind of seeking is
not supported. However, stereo files exported by libavcodec on
highest compression setting seem to work well.
Previously, ResampleHelper was fixed on handling double's, which makes
it unsuitable for the upcoming FLAC loader that needs to resample
integers. For this reason, ResampleHelper is templated to support
theoretically any type of sample, though only the necessary i32 and
double are templated right now.
The ResampleHelper implementations are moved from WavLoader.cpp to
Buffer.cpp.
This also improves some imports in the WavLoader files.
Previously, error_string() returned char* which is bad Serenity style
and caused issues when other error handling methods were tried. As both
WavLoader and (future) FLAC loader store a String internally for the
error message, it makes sense to return a String reference instead.
The existing InputBitStream methods only read in little endian, as this
is what the rest of the system requires. Two new methods allow the input
bitstream to read bits in big endian as well, while using the existing
state infrastructure.
Note that it can lead to issues if little endian and big endian reads
are used out of order without aligning to a byte boundary first.
Our Reference class now has the same fields as the spec:
- Base (a non-nullish value, an environment record, or `unresolvable`)
- Referenced Name (the name of the binding)
- Strict (whether the reference originated in strict mode code)
- ThisValue (if non-empty, the reference represents a `super` keyword)
The main difference from before is that we now resolve the environment
record that a reference interacts with. Previously we simply resolved
to either "local variable" or "global variable".
The associated abstract operations are still largely non-conforming,
since we don't yet implement proper variable bindings. But this patch
should at least fix a handful of test262 cases. :^)
There's one minor regression: some TypeError message strings get
a little worse due to doing a RequireObjectCoercible earlier in the
evaluation of MemberExpression.
This fixes a bug that occurs when the controller's ports are not
(internally) numbered sequentially.
This is done by checking the bits set in PI.
This bug was found on bare-metal, on a laptop with 1 Port that
was reported as port 4.
Multiboot only supports ELF32 executables. This changes the build
process to build an ELF32 executable which has a 32-bit entry point,
but consists of mostly 64-bit code.
Adds support for the :active pseudo-class for hyperlinks (<a> tags
only).
Also, since it was very similar to :focus and an element having a
focused state was already implemented, I went ahead and implemented
that pseudo-class too, although I cannot come up with a working
example to validate it.
This patch adds the alternate_shortcut member to LibGUI::Action, which
enables one Action to have two keyboard shortcuts.
Note that the string used in menus and tooltips only shows the main
shortcut, which is the same behaviour as in Firefox and Chrome.
At the moment these environments are always the same as the lexical
ones, so this didn't cause any trouble. Once we start separating them
we have to make sure both environments are protected.
