Mention the "Open Project Wizard" where you can set
the CMake options before making the cache.
Remind users to use the "Default" build type
and to build the Toolchain so CMake does not complain.
This patch implements spec-compliant runtime semantics for the following
constructs:
- super.property
- super[property]
The MakeSuperPropertyReference AO is added to support this. :^)
Right now we're using the FS segment for our per-CPU struct. On x86_64
there's an instruction to switch between a kernel and usermode GS
segment (swapgs) which we could use.
This patch doesn't update the rest of the code to use swapgs but it
prepares for that by using the GS segment instead of the FS segment.
These small changes fix the remaining warnings that come up during
kernel compilation with Clang. These specific fixes were for benign
things: unused lambda captures and braces around scalar initializers.
Aggregate initialization with brace-enclosed parameters is a
[C++20 feature][1] not yet implemented by Clang. This caused compile
errors if we tried to use the factory functions to create smart pointers
to aggregates.
As a (temporary) fix, [the LWG's previously proposed solution][2] is
implemented by this commit.
Now, wherever it's not possible to direct-initialize, aggregate
initialization is performed.

When creating uninitialized storage for variables, we need to make sure
that the alignment is correct. Fixes a KUBSAN failure when running
kernels compiled with Clang.
In `Syscalls/socket.cpp`, we can simply use local variables, as
`sockaddr_un` is a POD type.
Along with moving the `alignas` specifier to the correct member,
`AK::Optional`'s internal buffer has been made non-zeroed by default.
GCC emitted bogus uninitialized memory access warnings, so we now use
`__builtin_launder` to tell the compiler that we know what we are doing.
This might disable some optimizations, but judging by how GCC failed to
notice that the memory's initialization is dependent on `m_has_value`,
I'm not sure that's a bad thing.
The `#pragma GCC diagnostic` part is needed because the class has
virtual methods with the same name but different arguments, and Clang
tries to warn us that we are not actually overriding anything with
these.
Weirdly enough, GCC does not seem to care.
ResolveBinding now matches the spec, while the non-conforming parts
are moved to GetIdentifierReference.
Implementing this properly requires variable bindings.
This adds a test case for String::find and String::find_all with empty
needles. The expected behavior is in line with what the C++ standard
library (and other languages standard libraries) expect.
This implements StringUtils::find_any_of() and uses it in
String::find_any_of() and StringView::find_any_of(). All uses of
find_{first,last}_of have been replaced with find_any_of(), find() or
find_last(). find_{first,last}_of have subsequently been removed.
This adds the String::find_last() as wrapper for StringUtils::find_last,
which is another step in harmonizing the String and StringView APIs
where possible.
This also inlines the find() methods, as they are simple wrappers around
StringUtils functions without any additional logic.
This implements the StringView::find_all() method by re-implemeting the
current method existing for String in StringUtils, and using that
implementation for both String and StringView.
The rewrite uses memmem() instead of strstr(), so the String::find_all()
argument type has been changed from String to StringView, as the null
byte is no longer required.
This removes StringView::find_first_of(char) and find_last_of(char) and
replaces all its usages with find and find_last respectively. This is
because those two methods are functionally equivalent.
find_{first,last}_of should only be used if searching for multiple
different characters, which is never the case with the char argument.
This also adds the [[nodiscard]] to the remaining find_{first,last}_of
methods.
This patch reimplements the StringView::find methods in StringUtils, so
they can also be used by String. The methods now also take an optional
start parameter, which moves their API in line with String's respective
methods.
This also implements a StringView::find_ast(char) method, which is
currently functionally equivalent to find_last_of(char). This is because
find_last_of(char) will be removed in a further commit.
This patch refactors StringImpl::to_{lower,upper}case to use the new
static methods StringImpl::create_{lower,upper}cased if they have to use
to create a new StringImpl. This allows implementing StringView's
to_{lower,upper}case_string using the same methods.
It also replaces the usage of hand-written to_ascii_lowercase() and
similar methods with those from CharacterTypes.h.
This is used by VM::call_internal() and VM::construct() which roughly
map to function objects' [[Call]] and [[Construct]] slots in the spec.
Reorganizing this code revealed something weird: NativeFunction gets
its strictness by checking VM::in_strict_mode(). In other words,
it inherits the strict flag from the caller context. This is quite
weird, but many test-js tests rely on it, so let's preserve it until
we can think of something nicer.
This patch adds an override for NewExpression::execute() in the AST
interpreter to separate the logic from CallExpression. As a result,
both evaluation functions are simplified.
Both expressions are still largely non-conforming, but this makes
it easier to work on improving that since we can now deal with them
separately. :^)
Previously when opening an image with layers that had properties like
visibility set, PixelPaint would crash when trying to trigger
layer_did_modify_properties() without in image. Avoid this by
adding the layer to the image before setting the properties.
Sometimes you don't care about `joining()` the result of a thread. The
underlying pthread implementation already existed for detaching and
now we expose it to the higher level API.
It turns out that ccache caches are highly compressible (total size is
reduced by about 65%), so we should be able to increase the cache limit
for some free speedups. :^)
Specifically, instead of using the internal {get, put}_by_index methods
we now use the GetValueFromBuffer and SetValueInBuffer abstract
operations, as required by the specification.
While i was here i also replaced a couple custom detached array buffer
error messages with the existing ErrorType::DetachedArrayBuffer.
When searching in Assistant, we now dispatch some background jobs to
query the whole filesystem. Activating a result will use the Desktop
launcher's default way of opening that file or directory.
When launching Terminal via Taskbar we change to the users home
directory. For consistency, let's also `chdir` to `/home/anon` when
launching apps via Assistant's AppProvider.
